The controller 80 may determine whether the discharge flow path is blocked based on an average power consumption of the fan driving device 135 and a temperature change amount of heated air over time.

The controller 80 may calculate a discharge flow path blockage coefficient according to Equation 1 below based on the average power consumption of the fan driving device 135 and the temperature change amount of heated air over time.

FIG. 12 is a flowchart illustrating a control method of a clothes treating apparatus according to an embodiment of the disclosure.

Referring to FIG. 12, the clothes treating apparatus 1 according to an embodiment may start a drying operation based on a start condition of the drying operation being satisfied in operation 1100.

The controller 80 may drive the fan driving device 135 and/or the heater 120 based on the drying operation being started in operation 1200. In this case, the fan driving device 135 and the heater 120 may be driven simultaneously. In addition, the heater 120 may be driven after the fan driving device 135 is driven first. When the fan driving device 135 and the heater 120 are driven, heated air is supplied into the tub 20, and the air supplied into the tub 20 may be discharged to the outside of the housing 10 through the discharge flow path 146 after drying the laundry. In an embodiment of the disclosure, the controller 80 may control the driving device 36 to rotate the drum 30 during the drying operation.

When a washing course and a drying course are selected together and started according to user input, the controller 80 may perform the drying operation based on the washing course being terminated.

When only the drying course is selected and started independently according to user input, the controller 80 may perform the drying operation immediately.

In an embodiment of the disclosure, the controller 80 may calculate the average power consumption of the fan driving device 135 during a defined first unit time from a first time point in operation 1300. In this case, the first time point may be defined as an appropriate time point during the drying operation process. For example, the first time point may be defined as a time point when the drying operation is started.

In an embodiment of the disclosure, the controller 80 may calculate a heated air temperature change amount between a second time point and a third time point in operation 1400. The controller 80 may calculate the heated air temperature change amount based on temperatures obtained from the temperature sensor 86 at the second time point and the third time point. The second time point may correspond to a time point when the temperature obtained from the temperature sensor 86 reaches a defined reference temperature. In this case, the reference temperature may be defined as a specific temperature value (for example, 45° C.). According to various embodiments of the disclosure, the reference temperature may be defined as a temperature at a time point when the drying operation is started. Accordingly, the second time point may be the same time point as the first time point. The third time point may correspond to a time point when the temperature obtained from the temperature sensor 86 reaches a defined threshold temperature. In this case, the threshold temperature may be defined as a specific temperature value (for example, 90° C.). According to various embodiments of the disclosure, the threshold temperature may be defined as a temperature increased due to discharge flow path blockage compared to a state without discharge flow path blockage (i.e., a normal state).

In an embodiment of the disclosure, the controller 80 may determine whether the discharge flow path 146 is blocked based on the average power consumption of the fan driving device 135 and the calculated temperature change amount of the heated air over time in operation 1500. Specifically, the controller 80 may calculate a discharge flow path blockage coefficient Y based on the average power consumption of the fan driving device 135 and the calculated temperature change amount of the heated air over time according to Equation 1. Equation 1 is as follows.

Y = Y 2 / Y 1 × 1 ⁢ 0 ⁢ 0 Equation ⁢ 1

(Here, Y is a discharge flow path blockage coefficient, Y1 is an average power consumption of the fan driving device, and Y2 is a temperature change amount of heated air over time)

In an embodiment of the disclosure, the controller 80 may determine that the discharge flow path is blocked based on the magnitude of the discharge flow path blockage coefficient being equal to or greater than a defined threshold value. Accordingly, the controller 80 may control various components of the clothes treating apparatus 1 (for example, the heater 120, the fan driving device 135, and/or the thermostat 170) to perform an operation for clearing blockage of the discharge flow path 146.

In addition, the controller 80 may determine a discharge flow path blockage stage based on the magnitude of the discharge flow path blockage coefficient Y. Accordingly, the controller 80 may adjust an operation for clearing blockage of the discharge flow path 146 according to the discharge flow path blockage stage.

FIG. 13 is a flowchart illustrating discharge flow path blockage stages determined based on a degree of blockage in the discharge flow path of the clothes treating apparatus according to an embodiment of the disclosure.

Referring to FIG. 13, a table for determining whether a discharge flow path is blocked and a degree of discharge flow path blockage based on the magnitude of a discharge flow path blockage coefficient Y according to an embodiment is illustrated.

In an embodiment of the disclosure, the controller 80 may determine that the discharge flow path 146 is blocked based on the magnitude of the discharge flow path blockage coefficient Y being equal to or greater than a defined threshold value. Here, the defined threshold value may be defined as an appropriate value for calculating based on blockage of the discharge flow path 146. For example, the defined threshold value may be 14.

In addition, the controller 80 may determine a discharge flow path blockage stage based on the magnitude of the discharge flow path blockage coefficient Y. The discharge flow path blockage stage may be determined in stages according to a degree of blockage of the discharge flow path 146.

As an example, the discharge flow path blockage stage may include a first stage, a second stage, and a third stage. The smaller the degree of blockage of the discharge flow path 146, the smaller the number of stages (for example, the first stage), and the larger the degree of blockage of the discharge flow path 146, the larger the number of stages (for example, the third stage).

Hereinafter, the discharge flow path blockage stage having three stages is described as an example, but it should not be interpreted as being limited to the disclosure, and the discharge flow path blockage stage may have more or fewer than four stages.

For example, the controller 80 may determine the discharge flow path blockage stage as the first stage based on the magnitude of the discharge flow path blockage coefficient Y being equal to or greater than M1 and less than M2. For example, M1 and M2 may correspond to boundary values of the first stage.

For example, the controller 80 may determine the discharge flow path blockage stage as the second stage based on the magnitude of the discharge flow path blockage coefficient Y being equal to or greater than M2 and less than M3. For example, M2 and M3 may correspond to boundary values of the second stage.

For example, the controller 80 may determine the discharge flow path blockage stage as the third stage based on the magnitude of the discharge flow path blockage coefficient Y being equal to or greater than M3. For example, M3 may correspond to a boundary value of the third stage.

In this case, the controller 80 may determine a stage that is determined when the magnitude of the discharge flow path blockage coefficient Y is equal to or greater than a maximum value among a plurality of boundary values as a critical stage. For example, the controller 80 may determine a stage with the largest degree of blockage among the plurality of stages as the critical stage. In an example, the maximum value among the plurality of boundary values M1, M2, and M3 is M3, and the stage determined when the magnitude of the discharge flow path blockage coefficient Y is equal to or greater than M3 is the third stage, so the third stage may be determined as the critical stage.

The threshold value M1 for determining whether the discharge flow path is blocked and/or the boundary values M1, M2, and M3 for each discharge flow path blockage stage of the disclosure are merely examples and are not limited to the disclosure. According to various embodiments of the disclosure, the threshold value M1 for determining whether the discharge flow path is blocked and/or the boundary values M1, M2, and M3 for each degree of discharge flow path blockage may vary according to specifications of the clothes treating apparatus 1 or an installation environment of the clothes treating apparatus 1.

FIG. 14 is a flowchart for illustrating a process of performing a blockage clearing operation after detecting blockage in a discharge flow path in a method for controlling a clothes treating apparatus according to an embodiment of the disclosure.

Referring to FIG. 14, according to an embodiment of the disclosure, the controller 80 may determine a discharge flow path blockage stage in operation 2100. The controller 80 may determine the discharge flow path blockage stage according to the method described with reference to FIG. 13. In this case, the determined stage may be stored in the memory 82.

The controller 80 may determine whether the determined discharge flow path blockage stage corresponds to a critical stage in operation 2200. As described above, the critical stage may determine a stage with the largest degree of blockage among the plurality of stages as the critical stage.

The controller 80 may, based on the determined discharge flow path blockage stage not corresponding to the critical stage in No of operation 2200, adjust an output of the heater 120 according to the determined discharge flow path blockage stage in operation 2300. The output of the heater 120 corresponding to each stage may be defined and stored in the memory 82. For example, the output of the heater 120 for the first stage may be defined as 70% of the current output of the heater 120, the output of the heater 120 for the second stage may be defined as 50% of the current output of the heater 120, and the output of the heater 120 for the third stage may be defined as 30% of the current output of the heater 120. Accordingly, the controller 80 may determine an output value of the heater 120 based on the discharge flow path blockage stage. Thereafter, the controller 80 may control the heater 120 to reduce the output of the heater 120 to the determined output value of the heater 120. In this case, the controller 80 may change the output value at once for the heater 120 to have the determined output value. For example, when the determined output value of the heater 120 is 50% of the current output of the heater 120, the controller 80 may control the heater 120 to reduce the output of the heater 120 by 50% at once. In addition, the controller 80 may change the output value stepwise for the heater 120 to have the determined output value. For example, when the determined output value of the heater 120 is 50% of the current output of the heater 120, the controller 80 may control the heater 120 to reduce the output of the heater 120 stepwise from 100% to 70% to 50%. According to various embodiments of the disclosure, when the heater 120 is provided as a dual heater including a plurality of sub-heaters capable of operating independently, the controller 80 may independently control the plurality of sub-heaters to reduce a total output of the dual heater to the determined output of the heater 120.

Thereafter, the controller 80 may control at least one of a control temperature of the thermostat 170 or a rotation speed of the fan 130 in operation 2400.

The clothes treating apparatus 1 according to an embodiment may include a thermostat 170 configured to stop driving of the hot air supply device 110 based on a temperature of heated air supplied through the hot air supply device 110 exceeding a defined control temperature. In this case, the thermostat 170 may include a temperature sensor for detecting temperature. Accordingly, when the temperature detected by the thermostat 170 exceeds the control temperature, the controller 80 may terminate the drying operation.

The controller 80 may determine the control temperature according to the determined discharge flow path blockage stage. The control temperature corresponding to each stage may be defined and stored in the memory 82. For example, the control temperature may be defined as 90° C. for the first stage, 70° C. for the second stage, and 50° C. for the third stage. Accordingly, the controller 80 may determine the control temperature based on the discharge flow path blockage stage. Thereafter, the controller 80 may control the thermostat 170 according to the determined control temperature. In this case, the controller 80 may change the control temperature at once for the control temperature of the thermostat 170 to have the determined control temperature. For example, when the current temperature is 100° C. and the determined control temperature is 70° C., the controller 80 may control the thermostat 170 to change the control temperature of the thermostat 170 from 100° C. to 70° C. at once. In addition, the control temperature may be changed stepwise for the control temperature of the thermostat 170 to have the determined control temperature. For example, when the current temperature is 100° C. and the determined control temperature is 70° C., the controller 80 may control the thermostat 170 to reduce the control temperature of the thermostat 170 stepwise from 100° C. to 90° C. to 70° C.

The controller 80 may determine the rotation speed of the fan 130 according to the determined discharge flow path blockage stage. The rotation speed of the fan 130 corresponding to each stage may be defined and stored in the memory 82. For example, the rotation speed of the fan 130 may be defined as 3000 rpm for the first stage, 3200 rpm for the second stage, and 3400 rpm for the third stage. Accordingly, the controller 80 may determine the rotation speed of the fan 130 based on the discharge flow path blockage stage. Thereafter, the controller 80 may control the fan driving device 135 to increase rotation of the fan 130 based on the determined rotation speed. In this case, the controller 80 may change the rotation speed of the fan 130 at once for the fan 130 to rotate at the determined rotation speed. For example, when the current rotation speed is 2800 rpm and the determined rotation speed is 3200 rpm, the controller 80 may control the fan driving device 135 to change the rotation speed of the fan 130 from 2800 rpm to 3200 rpm at once. In addition, the controller 80 may change the rotation speed of the fan 130 stepwise to have the fan 130 rotate at the determined rotation speed. For example, when the current rotation speed is 2800 rpm and the determined rotation speed is 3200 rpm, the controller 80 may control the fan driving device 135 to increase the rotation speed of the fan 130 stepwise from 2800 rpm to 3000 rpm to 3200 rpm.

The controller 80 may determine whether a termination condition of the drying operation is satisfied in operation 2500. For example, when termination of the drying course is selected according to user input, the controller 80 may determine that the termination condition of the drying operation is satisfied. As another example, when a defined drying operation is completed or a defined drying operation time has elapsed, the controller 80 may determine that the termination condition of the drying operation is satisfied.

The controller 80 may, based on the termination condition of the drying operation being satisfied in Yes of operation 2500, terminate the drying operation. On the other hand, the controller 80 may, based on the termination condition of the drying operation not being satisfied in No of operation 2500, continue to perform the drying operation. The controller 80 may determine whether the discharge flow path is blocked and/or the discharge flow path blockage stage while performing the drying operation, and may perform an operation for clearing the discharge flow path blockage.

The controller 80 may, based on the determined discharge flow path blockage stage corresponding to the critical stage in Yes of operation 2200, determine whether the critical stage has been consecutively determined for a defined number of times based on information stored in the memory 82. Here, the defined number of times may be defined as an appropriate number of times in operation 2600. For example, the defined number of times may be defined as 4 times.

The controller 80 may, based on the controller 80 not having consecutively determined the critical stage for the defined number of times in No of operation 2600 adjust the output of the heater according to the determination as the critical stage in operation 2300. Simultaneously or sequentially, the controller 80 may adjust at least one of the control temperature of the thermostat 170 or the rotation speed of the fan 130.

The controller 80 may, based on the controller 80 having consecutively determined the critical stage for the defined number of times in Yes of operation 2600, control the hot air supply device 110 to terminate the drying operation in operation 2700. Here, the case where the critical stage has not been consecutively determined for the defined number of times may include a case where the critical stage is determined for fewer times than the defined number of times consecutively, or a case where the critical stage is determined non-consecutively even when determined for the defined number of times. The controlling of the hot air supply device 110 to terminate the drying operation may include stopping the driving of the heater 120 and/or the fan 130.
