Next, the support unit 80 will be described with reference to FIGS. 1 to 4. FIG. 3 is a side view of the microwave grill device 100 as viewed from a right side. FIG. 4 is a side view of the microwave grill device 100 from which the right panel 61 and the left panel 62 are removed, as viewed from the right side. FIG. 5 is a view illustrating a positional relationship among the first heating unit 20, the operation unit 40, and the support unit 80. FIG. 6 is an exploded perspective view illustrating the positional relationship among the first heating unit 20, the operation unit 40, and the support unit 80.
As illustrated in FIGS. 3 to 6, the support unit 80 includes placement portions 81A and 81B and column portions 82A and 82B. The first heating unit 20 is placed on the placement portion 81A and the placement portion 81B. The column portions 82A and 82B extend downward from the placement portion 81A and the placement portion 81B, respectively.
Specifically, the placement portion 81A and the placement portion 81B are provided below the lower wall 33 so as to be in contact with the lower wall 33. The placement portion 81A and the placement portion 81B are provided so as to extend over the entire width of the first heating unit 20 along the left-right direction (second direction D2).
In the present embodiment, the width of the placement portion 81A and the placement portion 81B in the front-rear direction (first direction D1) is shorter than the width of the first heating unit 20 (plate 30) in the front-rear direction (first direction D1). That is, the width of the placement portion 81A and the placement portion 81B in the front-rear direction (first direction D1) occupies only a part of the width of the first heating unit 20 (plate 30) in the front-rear direction (first direction D1). In this manner, the first heating unit 20 can be supported with a simple configuration. In addition, the first heating unit 20 and the support unit 80 can be moved together, and the microwave grill device 100 can be installed at a wider range of locations.
As illustrated in FIG. 4, the placement portion 81A extends below the first radiant heater 21 and the second radiant heater 22 (first heating device) in the left-right direction (second direction D2). The placement portion 81A is an example of the first placement portion. The placement portion 81B extends below the third radiant heater 23, the fourth radiant heater 24, and the fifth radiant heater 25 (second heating device) in the left-right direction (second direction D2). The placement portion 81B is an example of the second placement portion. In this manner, the placement portion 81A and the placement portion 81B are positioned apart from each other in the front-rear direction (first direction DI). Therefore, the placement portion 81A and the placement portion 81B can support the first heating unit 20 while balancing the weight in the front-rear direction (first direction D1).
More specifically, the placement portion 81A is provided at a position not including a position C1 indicating the center of the first radiant heater 21 and the center of the second radiant heater 22 in the front-rear direction (first direction D1). Specifically, the placement portion 81A is provided on the front side of the position C1. The placement portion 81B is provided at a position including a position C2 indicating the center of the third radiant heater 23, the center of the fourth radiant heater 24, and the center of the fifth radiant heater 25 in the front-rear direction (first direction D1). Specifically, the placement portion 81B is provided over the front side of the third radiant heater 23, the fourth radiant heater 24, and the fifth radiant heater 25 including the position C2 in the front-rear direction (first direction D1) and the rear side of the third radiant heater 23, the fourth radiant heater 24, and the fifth radiant heater 25. That is, the placement portion 81B passes below the position C2. In addition, the placement portion 81B is provided to support the rear side of the second heating device.
Therefore, the placement portion 81A and the placement portion 81B can support the first heating unit 20 while balancing the weights of the first heating device, the second heating device, and the operation unit 40 in the front-rear direction (first direction D1).
As illustrated in FIGS. 4 and 6, the column portion 82A includes a pair of columns 82a and 82b. The pair of columns 82a and 82b of the column portion 82A face each other in the left-right direction (second direction D2). The column portion 82B includes a pair of columns 82a and columns 82b. The pair of columns 82a and 82b of the column portion 82B face each other in the left-right direction (second direction D2). The widths of the column portion 82A and the column portion 82B in the front-rear direction (first direction D1) are the same as the widths of the placement portion 81A and the placement portion 81B in the front-rear direction (first direction D1), respectively.
The microwave heating/cooking chamber 70 is disposed between the column 82a and the column 82b of the column portion 82A and between the column 82a and the column 82b of the column portion 82B. The column 82a of the column portions 82A is connected to the right wall 71 of the microwave heating/cooking chamber 70. The column 82a of the column portion 82B is connected to the right wall 71 of the microwave heating/cooking chamber 70. The column 82b of the column portion 82A is connected to the left wall 72 of the microwave heating/cooking chamber 70. The column 82b of the column portion 82B is connected to the left wall 72 of the microwave heating/cooking chamber 70.
For example, the column portion 82A and the column portion 82B are directly attached to the microwave heating/cooking chamber 70. Accordingly, the first heating unit 20 can be disposed above the microwave heating/cooking chamber 70 with a small number of components.
In the present embodiment, the placement portion 81A and the placement portion 81B have the same shape. In addition, the column portion 82A and the column portion 82B have the same shape. Specifically, the column 82a of the column portion 82A and the column 82a of the column portion 82B have the same shape. The column 82b of the column portion 82A and the column 82b of the column portion 82B have the same shape. Further, the pair of columns 82a and 82b have the same shape. That is, the column 82a of the column portion 82A, the column 82a of the column portion 82B, the column 82b of the column portion 82A, and the column 82b of the column portion 82B have the same shape. Therefore, a plurality of the same components can be easily manufactured, and manufacturing cost can be reduced.
Note that in the present embodiment, the number and combination of the placement portions and the column portions provided in the microwave grill device 100 are not particularly limited. For example, two placement portions and a pair of column portions may be provided, or two or more pairs of column portions may be provided for one placement portion. In addition, the widths of the placement portion and the column portion in the front-rear direction (first direction D1) may be different from each other. Further, the widths of the placement portion and the column portion in the front-rear direction (first direction D1) may occupy the entire width of the first heating unit 20 (plate 30) in the front-rear direction (first direction D1).
Next, a panel member 60 provided in the microwave grill device 100 will be described with reference to FIGS. 3 to 5.
In the present embodiment, the lengths of the column portion 82A and the column portion 82B in the up-down direction (third direction D3) are larger than the lengths of the microwave heating/cooking chamber 70 in the up-down direction (third direction D3). As a result, as illustrated in FIG. 4, a space S1 is formed between the upper wall 73 of the microwave heating/cooking chamber 70 and the lower wall 33 of the grill chamber 39 and between the upper wall 73 of the microwave heating/cooking chamber 70 and the placement portions 81A and 81B.
In the microwave grill device 100, the panel member 60 is provided so as to close at least a part of the front side of the space S1. Specifically, in the microwave grill device 100, the operation housing 400 and the front door 76 are positioned apart from each other in the up-down direction (third direction D3). The panel member 60 is provided between the operation housing 400 and the front door 76. The panel member 60 is a substantially rectangular plate-shaped member. Typically, the panel member 60 is attached above the opening 701 in the microwave heating/cooking chamber 70. The operation housing 400 and the panel member 60 are provided so as to close the front side of the space S1.
The heat generated from the first heating unit 20 by heating by the first heating unit 20 and the heat generated from the microwave heating/cooking chamber 70 by heating by the microwave supply unit 89 are transferred to the space S1. As a result, the space S1 tends to have a high temperature. Therefore, by providing the panel member 60, it is possible to block the high-temperature air in the space SI from moving to the front side. As a result, heat is less likely to be transferred to the cook positioned in front of the operation unit 40, and the cook can comfortably operate the operation unit 40.
Next, the appearance of the microwave grill device 100 from a front and obliquely upper view will be described with reference to FIGS. 3 to 5 and 7. FIG. 7 is a view illustrating the microwave grill device 100 as viewed from a front and obliquely upper side.
As illustrated in FIG. 3, the operation housing 400 has a first inclined surface F1 inclined upward from the lower surface of the operation housing 400 toward the front side. By providing the first inclined surface F1, for example, when the cook looks down on the operation panel 45 from an obliquely upper front view, the panel member 60 becomes easily noticeable. Typically, an end 761 of the front door 76 on the front side is positioned on the front side of a virtual plane F3 obtained by extending the first inclined surface F1. Therefore, when the cook looks down on the operation panel 45 from the obliquely upper front view, the front door 76 becomes easily noticeable in addition to the panel member 60.
Further, in the microwave grill device 100, the front end 761 of the front door 76 and the front end 601 of the panel member 60 are aligned in the front-rear direction (first direction D1). Accordingly, it is possible to give a visual sense of unity to the panel member 60 and the front door 76 while suppressing a decrease in visibility between the panel member 60 and the front door 76.
Next, details of the operation unit 40 will be described with reference to FIGS. 3 to 5 and FIGS. 8 to 10. FIG. 8 is a view illustrating a rear side of the operation unit 40. FIG. 9 is an exploded perspective view of the operation unit 40. FIG. 10 is an exploded perspective view of the operation unit 40 at another angle. Note that FIGS. 8 to 10 illustrate the front frame 63 in addition to the operation unit 40.
As illustrated in FIGS. 8 to 10, the operation housing 400 includes a base portion 401, a housing portion 402, and a cover portion 403. The base portion 401 constitutes a bottom of the operation housing 400. The lower surface and the first inclined surface F1 are formed on the base portion 401. For example, the base portion 401 is made of resin.
The housing portion 402 is disposed above the base portion 401. The first dial 41, the second dial 42, the third dial 43, the fourth dial 44, and the operation panel 45 are disposed in the housing portion 402. Specifically, the first dial 41, the second dial 42, the third dial 43, the fourth dial 44, and the display device (display surface) of the operation panel 45 are disposed to be exposed from the housing portion 402. In the operation housing 400, in a space surrounded by the housing portion 402 and the base portion 401, components other than the display device (display surface) of the operation panel 45 are housed. For example, the housing portion 402 is made of resin.
The housing portion 402 has a second inclined surface F2. As illustrated in FIGS. 3 to 5, the second inclined surface F2 is inclined with respect to the plate 30 of the first heating unit 20 in the up-down direction (third direction D3). Specifically, the second inclined surface F2 is inclined obliquely downward on the front side. The display device of the operation panel 45 is disposed on the second inclined surface F2. Accordingly, in a case where the length in the front-rear direction (first direction D1) is the same as that of the operation housing 400, the length of the display device in a longitudinal direction can be increased as compared with a case where the display device of the operation panel 45 is disposed on a horizontal plane. Therefore, the display area of the operation panel 45 can be increased.
The cover portion 403 covers the housing portion 402 and forms the second inclined surface F2. For example, the cover portion 403 is made of metal.
Next, attachment of the operation housing 400 will be described with reference to FIGS. 4, 5, 8, and 10.
As illustrated in FIGS. 4, 5, 8, and 10, the operation housing 400 has a pair of connection portions 410. The pair of connection portions 410 is connected to the first heating unit 20. Specifically, the pair of connection portions 410 is provided at both ends of the base portion 401 in the left-right direction (second direction D2) in the operation housing 400. Each of the pair of connection portions 410 is provided so as to protrude toward the rear side of the operation housing 400. The pair of connection portions 410 is attached to the front frame 63. Specifically, the front frame 63 includes a first support member 63A and a second support member 63B. The first support member 63A is in contact with the rear surface and the lower surface of the base portion 401. In addition, the first support member 63A has a shape extending along the pair of connection portions 410. The second support member 63B is disposed on the rear side of the first support member 63A.
Accordingly, the operation housing 400 is supported with respect to the first heating unit 20 at both ends in the left-right direction (second direction D2). Thus, the operation housing 400 can be stably supported as compared with a case where only the lower surface of the operation housing 400 is supported.
Specifically, each of the pair of connection portions 410 has a shape extending in the up-down direction (third direction D3). Typically, each of the pair of connection portions 410 is a substantially rectangular plate-shaped member. The connection portion 410 has at least two attachment portions 411 attached to the first heating unit 20. For example, the connection portion 410 is screwed to the first support member 63A. That is, a through hole through which a screw passes is provided as the attachment portion 411 in the connection portion 410. The two attachment portions 411 are disposed side by side in the up-down direction (third direction D3). Accordingly, the connection portion 410 is supported by the first heating unit 20 at least at two points arranged in the up-down direction (third direction D3). As a result, the operation housing 400 is less likely to rotate in the up-down direction (third direction D3), and the posture of the operation unit is likely to be stabilized.
As illustrated in FIGS. 8 and 9, the operation housing 400 includes a hook 421 which is hooked on the first support member 63A and the second support member 63B positioned on the front side of the first heating unit 20. Specifically, one or more through holes 341 are provided in the first support member 63A. The hook 421 corresponding to the through hole 341 is provided on the rear surface of the operation housing 400. In the present embodiment, the hook 421 is provided in the base portion 401, but may be provided in the housing portion 402 or the cover portion 403. The hook 420 has a shape that curves convexly upward. The hook 421 is hooked on an edge of the through hole 341. Note that the hook 421 may be hooked on the second support member 63B together with the edge of the through hole 341.
The hook 421 makes it difficult for the operation housing 400 to move with respect to the front wall 34 in the front-rear direction (first direction D1), and the posture of the operation unit is easily stabilized.
As illustrated in FIGS. 8 to 10, the operation housing 400 has a side wall portion 430. Typically, the side wall portions 430 are provided at both ends of the housing portion 402 in the left-right direction (second direction D2) in the operation housing 400. The side wall portion 430 has a vent hole 431. The vent hole 431 is formed by, for example, a plurality of slits 432 penetrating the side wall portion 430. Note that the vent hole 431 may be one through hole penetrating the side wall portion 430. The vent hole 431 is an example of the first vent hole. The size, shape, and number of the slits 432 are not particularly limited.
By providing the vent hole 431 in the operation housing 400, the air permeability of the operation housing 400 is improved. As a result, a rise in temperature of the operation housing 400 due to the heating of the first heating unit 20 or the heating of the microwave supply unit 89 can be suppressed. Note that the vent hole 431 is not limited to the side wall portion 430, and may be provided on any surface of the operation housing 400. For example, the vent hole 431 may be provided on the lower surface of the operation housing 400.
As illustrated in FIG. 9, the operation housing 400 includes a blower fan 440 that supplies air to the operation housing 400. In the present embodiment, the operation housing 400 includes two blower fans 440A and 440B. By providing the blower fan 440 in the operation housing 400, it is possible to efficiently exchange the air inside the operation housing 400 and improve the heat dissipation of the operation housing 400. Typically, the blower fans 440A and 440B are controlled by the control unit 50.
The operation housing 400 has an air supply chamber 450 connected to the vent hole 431. In the present embodiment, the operation housing 400 includes two air supply chambers 450A and 450B. The air supply chamber 450A is connected to the vent hole 431 provided in the right side wall portion 430 of the operation housing 400. The air supply chamber 450B is connected to the vent hole 431 provided in the left side wall portion 430 of the operation housing 400. That is, the air supply chamber 450A is provided on the right side of the operation housing 400. The air supply chamber 450B is provided on the left side of the operation housing 400.
Specifically, the operation housing 400 has a partition portion 451A facing the right side wall portion 430 and a partition portion 451B facing the left side wall portion 430. The partition portion 451A and the partition portion 451B are provided in the housing portion 402. The partition portion 451A is positioned on the left side of the right side wall portion 430. The partition portion 451B is positioned on the right side of the left side wall portion 430. Therefore, the air supply chamber 450A is formed between the right side wall portion 430 and the partition portion 451A. The air supply chamber 450B is formed between the left side wall portion 430 and the partition portion 451B.
The air supply chamber 450A has a vent hole 452A different from the vent hole 431. The air supply chamber 450B has a vent hole 452B different from the vent hole 431. In addition, the blower fan 440A is disposed in the air supply chamber 450A. The blower fan 440B is disposed in the air supply chamber 450B. When the blower fan 440A or 440B is driven, air is supplied from the vent holes 431 to the air supply chamber 450A or the air supply chamber 450B, and the air in the air supply chamber 450A or the air supply chamber 450B is exhausted from the air supply chamber 450A or the air supply chamber 450B through the vent hole 452A or the vent hole 452B, respectively. In this manner, air can be efficiently supplied into the operation housing 400. The vent holes 452A and 452B are an example of the second vent hole.
For example, the vent hole 452A is provided in the partition portion 451A. The vent hole 452B is provided in the partition portion 451B. That is, the vent hole 452A faces the right vent hole 431 in the left-right direction (second direction D2). The vent hole 452B faces the left vent hole 431 in the left-right direction (second direction D2). Therefore, an air passage from the right vent hole 431 to the vent hole 452A and an air passage from the left vent hole 431 to the vent hole 452B become linear, and air easily passes through the air supply chamber 450A or the air supply chamber 450B.
In the present embodiment, the vent hole 431 is provided on the front side of the vent hole 452A and the vent hole 452B. Specifically, the vent hole 431 is disposed on the front side in the front-rear direction (first direction D1) in the side wall portion 430. The vent hole 452A and the vent hole 452B are disposed on the rear side in the front-rear direction (first direction D1). In this manner, by providing the vent holes 431 at positions farther from the heat sources of the first heating unit 20 and the microwave supply unit 89 than the vent hole 452A and the vent hole 452B, colder air is easily supplied into the operation housing 400.
The operation housing 400 has a plurality of vent holes 470 on the lower surface. Air having passed through the air supply chamber 450A or the air supply chamber 450B is exhausted from the vent hole 470 to the outside of the operation housing 400. The vent hole 470 is an example of the third vent hole. For example, the vent hole 470 is positioned behind the front end 601 of the panel member 60. Therefore, the air exhausted from the vent hole 470 is less likely to directly hit the cook.
Next, the air supply chamber 450A and the air supply chamber 450B will be described with reference to FIGS. 8 to 12. FIG. 11 is an enlarged view of the air supply chamber 450A. FIG. 12 is an enlarged view of the air supply chamber 450B.
As illustrated in FIGS. 8 to 12, the direction of the blower fan 440A disposed in the air supply chamber 450A is different from the direction of the blower fan 440B disposed in the air supply chamber 450B. Accordingly, air blowing by the blower fan 440A and air blowing by the blower fan 440B are generated at different positions inside the operation housing 400. Therefore, air can easily pass through a wider range inside the operation housing 400.
For example, the blower fan 440A is disposed along the front-rear direction (first direction D1). The blower fan 440B is disposed along a direction intersecting the front-rear direction (first direction D1). Typically, the blower fan 440B is disposed along the up-down direction (third direction D3). Specifically, the blower fan 440B is a centrifugal fan (sirocco fan). The rotation shaft of the blower fan 440A and the rotation shaft of the blower fan 440B are disposed to extend along the front-rear direction (first direction D1) and the up-down direction (third direction D3), respectively.
The vent hole 452A of the air supply chamber 450A has a shape extending in the up-down direction (third direction D3). The vent hole 452B of the air supply chamber 450B has a shape extending in the front-rear direction (first direction D1). By making the shape of the vent hole 452A and the shape of the vent hole 452B correspond to the direction of the blower fan 440A and the direction of the blower fan 440B, respectively, air can be efficiently supplied into the operation housing 400.
For example, the vent hole 452A is provided on the first heating unit 20 side (rear side) of the operation housing 400. The vent hole 452B is provided on the second inclined surface F2 side. Accordingly, it is possible to suppress a rise in the temperatures of the front side of the plate 30 which tends to be hot and the second inclined surface F2 which is the operation surface of the operation unit.
The vent hole 431 includes a partition wall 460 which separates each of the plurality of slits 432.
The partition wall 460 is provided on the air supply chamber 450 side of the side wall portion 430. The partition wall 460 has a shape bent toward the side opposite to the blower fan 440A or the blower fan 440B. For example, the partition wall 460 is bent toward the front side. Accordingly, the air supplied to the air supply chamber 450A through the slit 432 also moves to the front side along the partition wall 460. This allows cool air to reach a wider area, and makes the blower fan 440A less visible from the outside of the operation housing 400.
As illustrated in FIG. 4, in the present embodiment, the microwave grill device 100 includes a wiring portion 501. A cable CA extending from the operation unit 40 is wired to the wiring portion 501. For example, the wiring portion 501 is a terminal block. The wiring portion 501 is disposed on a side opposite to the operation unit 40 with respect to the first heating unit 20. Specifically, the wiring portion 501 is attached to the rear side of the rear wall 35 of the grill chamber 39. In addition, a wiring hole 342 through which the cable CA extending from the operation unit 40 passes is provided on the rear surface of the operation housing 400. The cable CA passing through the wiring hole 342 passes, for example, below the grill chamber 39 and is wired to the wiring portion 501.
In this manner, by providing the wiring portion 501 outside the operation unit 40, it is easy to secure an air passage inside the operation housing 400.
