Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention according to specific situations.

In addition, the technical solutions of the various embodiments of the present invention can be combined with each other, but it must be based on the realization of those skilled in the art. When the combination of technical solutions is contradictory or cannot be realized, it should be considered as a combination of technical solutions. Does not exist, nor is it within the scope of protection required by the present invention. Regarding the control method of the laundry treatment equipment, the control method of the laundry treatment equipment is applied to the laundry treatment equipment with a drying system and a laundry system, wherein it can be understood that the laundry treatment equipment includes a clothes dryer or an integrated washer-dryer and the like. Among them, clothes dryers include heat pump clothes dryers, condensation clothes dryers and inline clothes dryers. Taking the heat pump dryer as an example, the heat pump dryer includes a condenser, an evaporator, a fan, a water tank, and a water storage box. Drying, the dried low-temperature and high-humidity air flows through the evaporator, and condenses the water vapor on the surface of the evaporator. The water generated by the condensation is discharged into the water tank for temporary storage, and then discharged into the water storage box through the drainage device. User removal processing.

Referring to FIG. 1 , it is a schematic structural diagram of the drainage device of the clothes treatment device. It can be seen from FIG.

Wherein, during the clothes drying process of the clothes treatment device, the airflow discharged from the barrel of the clothes treatment device will be condensed into condensed water and flow into the water tank 1 for storage, and the condensed water collected in the water tank 1 will be pumped by the drain pump 3 through the drain pipe 4 into the water storage box 2.

The working principle of the drainage pump 3 pumping the condensed water to the water storage box 2 is: during the operation of the drainage pump 3, relying on the high-speed rotating impeller, the water obtains energy under the action of the inertial centrifugal force, increases the pressure, and flies from the blades. After the water in the drainage pump 3 is thrown out, the central part of the impeller forms a vacuum area, and the water in the water tank 1 is pressed in under the action of atmospheric pressure, so that the cycle is endless, and the condensed water in the water tank 1 is pumped continuously into the water storage box 2.

In addition, after the drying of the clothes treatment device is completed, when the water in the water storage box 2 is full, if the user forgets to pour out the water in the water storage box 2, the water in the water storage box 2 will flow back through the return pipe 5 into sink 1.

At present, in the process of drying clothes in the clothes processing device, under normal circumstances, the drain pump 4 starts to drain water at regular intervals, for example, every 6 minutes, the drain pump 4 runs for 30 seconds to drain water.

Moreover, during the stoppage of the drainage pump 4, the water level in the water tank 1 will be detected in real time, and when the detected water level exceeds the upper water level limit, even if it has not reached the running time of the drainage pump 4, the operation of the drainage pump 4 will also be controlled. , and continue for a relatively long period of time, for example, continuously run for 1 minute, if the water level in the water tank 1 still exceeds the high water level limit after the drain pump 4 continues to run for a relatively long period of time, the clothes processing device will alarm and stop.

The reason for the above alarm and shutdown is: under certain working conditions, when there is air in the drainage pump, the air will form an air bag in the drainage pump, block the flow channel, and the working ability of the impeller will decrease, and the condensed water cannot be discharged in time, resulting in The water level in the tank has been rising. When it is detected that the water level in the sink is higher than the maximum water level limit, the laundry treatment device can only alarm and stop. Therefore, the existing drainage program cannot solve this problem, so for those who cannot achieve real-time monitoring It will cause waste of time and resources for users.

In order to solve the above-mentioned technical problems, the present invention proposes a drainage control method of a clothes treatment device. When the water tank full alarm signal for collecting condensed water in the clothes treatment device is detected, the drainage pump in the clothes treatment device is controlled to perform intermittent drainage. run to allow air to escape from the drain pump.

Based on the above description, it can be seen that when the water tank is full alarm signal is detected, it means that the drain pump may be unable to discharge the condensed water in the tank according to the normal drainage procedure due to trapped air. The drain pump is controlled to run intermittently, especially when the drain pump stops running. During this time, the water will flow back to fill the drain pump, which will push the air in the drain pump down the drain. In this way, when the drainage pump runs again, part of the condensed water in the water tank can be discharged, so that the water tank is full and the alarm signal is eliminated, and then the drainage pump returns to the drainage procedure under normal conditions.

In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

Embodiment one:

Fig. 2 is a schematic flow chart of an embodiment of a drainage control method for a laundry treatment device according to an exemplary embodiment of the present invention. The laundry treatment device to which the drainage control method is applicable includes the drainage device shown in Fig. 1 , as shown in FIG. As shown in Figure 2, the drainage control method includes the following steps:

Step 201: Detect whether there is an alarm signal of full water in the water tank in the laundry treatment device, if yes, execute step 202, if not, continue to execute step 201.

In the embodiment of the present application, combined with the above-mentioned FIG. 1, the water full alarm signal indicates that even if the drain pump 3 is started for a period of time to drain water every certain period of time according to the normal situation, the condensed water collected in the water tank 1 is also full. It shows that the drain pump 3 may be unable to discharge the condensed water in the water tank 1 according to the normal drain procedure due to trapped air.

The principle of trapped air in the drainage pump 3 is as follows: when the drainage pump 3 starts running, if there is air in the drainage pump 3, since the density of the air is very low, the centrifugal force generated after the rotation of the impeller is very small, so the center of the impeller forms The low pressure is not enough to suck the condensed water in the water tank 1 into the drain pump 3, so the drain pump 3 will be trapped and cannot pump out the condensed water.

It can be understood that, if no water full alarm signal is detected, it means that the condensed water collected in the water tank 1 can be discharged according to the start cycle of the drain pump 3 under normal conditions.

It should be noted that, for the specific generation process of the water full alarm signal, reference may be made to the detailed description of the following embodiments, which will not be described in detail in this application.

Step 202: Control the drainage pump of the laundry treatment device to run intermittently.

Among them, the intermittent operation of the drainage pump refers to running for a period of time and then stopping for a period of time, especially during the stoppage of the drainage pump, after the high pressure at the outlet of the drainage pump is balanced with the low pressure at the center of the impeller, the water will flow back to fill the drainage pump, Thereby, the air in the drain pump is discharged along the drain pipe, so that when the drain pump is restarted, the water can be pumped normally.

It should be noted that, for the specific process of controlling the drainage pump to perform intermittent operation, reference may be made to the detailed description of the following embodiments, which will not be described in detail in this application.

So far, the control process shown in Figure 2 above is completed. Through the control process shown in Figure 2, when the water tank full alarm signal of the laundry treatment device is detected, it means that the drainage pump may be unable to discharge the water tank according to the normal drainage procedure due to trapped air. The condensed water in the drain pump is intermittently operated by controlling the drain pump, especially when the drain pump stops running, the water will flow back to fill the drain pump, so that the air in the drain pump will be discharged along the drain pipe. In this way, when the drainage pump runs again, part of the condensed water in the water tank can be discharged, so that the water tank is full and the alarm signal is eliminated, and then the drainage pump returns to the drainage procedure under normal conditions.

Embodiment two:

Fig. 3 is a schematic flowchart of an embodiment of another drainage control method of a laundry treatment device according to an exemplary embodiment of the present invention. Based on the above embodiment shown in Fig. 2, as shown in Fig. 3, the clothes The drainage control method of the treatment device includes the following steps:

Step 301: When it is detected that the water level in the water tank is continuously higher than the preset water level, a water full alarm signal is generated.

In the embodiment of the present application, referring to the above-mentioned FIG. 1 , the drainage device may further include a water level sensor disposed in the water tank 1 for detecting the water level of the condensed water in the water tank 1 .

In an optional specific implementation manner, the process of detecting that the water level in the water tank is continuously higher than the preset water level includes the following steps:

Step 3011: start timing according to detecting that the water level in the water tank is higher than the preset water level.

Wherein, the preset water level is the maximum water level limit value of the water tank, and if the water level is higher than the preset water level, it means that the water tank is full.

Step 3012: During the timing period, detect the water level in the water tank according to the preset cycle.

Wherein, the preset period is the detection period of the water level sensor, for example, the water level sensor can detect the water level of the condensed water in the water tank every 20 milliseconds.

Step 3013: Stop the detection according to the timing reaching the first preset duration, and determine that the water level in the water tank is continuously higher than the preset water level according to the detected water levels during the timing period being higher than the preset water level.

Among them, the first preset duration can be set according to actual needs. The longer it is set, the more times the water level will be detected continuously. Of course, it cannot be set too long to avoid overflow of condensed water in the water tank during the continuous detection period.

It can be understood that if the detected water level is higher than the preset water level each time during the timing period, it means that the condensed water in the sink cannot be drained according to the normal drainage procedure.

Step 302: Based on the water full alarm signal, control the drain pump of the laundry treatment device to perform intermittent operation.

So far, the above-mentioned control flow shown in Figure 3 is completed. Through the control flow shown in Figure 3, the application detects that the water level in the water tank is continuously higher than the preset water level, and generates a water full alarm signal, that is, Only when the water level in the water tank is detected to be higher than the preset water level for several times in a row, the water full alarm signal is generated, so that the problem of false alarm can be avoided. In order to eliminate the problem of water tank full alarm due to trapped air in the drain pump, intermittent operation is performed by controlling the drain pump, especially during the stop operation of the drain pump, the water will flow back to fill the drain pump, so that the air in the drain pump will be drained along tube discharge. In this way, when the drainage pump runs again, part of the condensed water in the water tank can be discharged, so that the water tank is full and the alarm signal is eliminated, and then the drainage pump returns to the drainage procedure under normal conditions.

Embodiment three:

Fig. 4 is a schematic flow chart of another embodiment of a drainage control method for a laundry treatment device according to an exemplary embodiment of the present invention. Based on the above embodiments shown in Fig. 2 to Fig. 3 , as shown in Fig. 4 , The drainage control method of the laundry treatment device includes the following steps:

Step 401: Obtain the number of times the drainage pump alternates between stopping and running during the intermittent operation process according to the detected water tank full alarm signal.

It should be noted that, for the process of detecting the water tank full alarm signal, reference may be made to the relevant descriptions in the above embodiments, and the present application will not describe it in detail here.

In an optional specific implementation, for the process of obtaining the number of alternate times of stop and run during the intermittent operation of the drainage pump, the number of alternate times may be preset according to experimental calibration. For example, after the experimental test calibration, in the case of the drainage pump trapped air, after the drainage pump goes through the process of running → stopping → running, the air in the drainage pump is discharged, and the water level in the tank is also discharged to be lower than the maximum water level The limit value and the number of alternations can be preset to 2 times.

In another optional specific implementation, the number of alternations can also be determined in real time according to the current situation of the laundry treatment device. For example, the number of alternations for the intermittent operation of the drainage pump can be determined according to the current water level in the tank. There is a positive correlation.

Step 402: Control the drainage pump to perform intermittent operation according to the alternate times.

In an optional specific implementation manner, the process of controlling the drainage pump to perform intermittent operation according to the number of alternations includes the following steps:

Step 4021: Decrease the number of alternations by 1 each time the drain pump is controlled to run for a second preset time and then stop for a third preset time.

Step 4022: When the number of alternations is 0, end the intermittent operation process of the drainage pump.

Among them, in order to ensure the intermittent operation of the drainage pump, the water level in the tank can be discharged below the maximum water level limit value, the total running time of the drainage pump needs to exceed the minimum drainage time.

That is to say, the product of the second preset duration and the number of alternations is greater than the preset minimum drainage duration.

Wherein, the minimum drainage time refers to the minimum time required to drain the water level in the water tank below the maximum water level limit value.

For example, assuming that the minimum drainage duration is 1 minute and the number of alternations is set to 2, then the second preset duration is required to be 30 seconds, and if the third preset duration is set to 10 seconds, that is, the intermittent operation process of the drainage pump is running 30 seconds → stop for 10 seconds → run for 30 seconds.

So far, the above-mentioned control flow shown in Figure 4 is completed. Through the control flow shown in Figure 4, when the water full alarm signal is detected, the number of times the drainage pump stops and runs during intermittent operation is obtained, and according to the described Alternate times control the drainage pump to run intermittently to ensure that the air in the drainage pump is completely discharged, and at the same time, the water level in the tank can be discharged below the maximum water level limit value, and the water full alarm signal can be eliminated.

Embodiment four:

Step 501: Control the drain pump of the laundry treatment device to run intermittently according to the detected water tank full alarm signal.

It should be noted that, for the process of step 501, reference may be made to the relevant descriptions of the foregoing embodiments, which will not be described in detail in this application.

Step 502: When it is detected that the water level in the water tank is continuously higher than the preset water level, an alarm is issued, and the clothes processing device is switched from the running state to the closed state.

In an optional specific embodiment, an alarm component can be set in the clothes processing device. If the water level in the water tank is still higher than the preset water level after the intermittent operation of the drain pump, the alarm reminder will be issued through the alarm component, and timely Remind users to pay attention.

So far, the above-mentioned control process shown in Figure 5 is completed. Through the control process shown in Figure 5, according to the detection of the water tank full alarm signal, after controlling the drainage pump of the clothes treatment device to perform intermittent operation, if it is detected that the water level in the water tank is still If the water level continues to be higher than the preset water level, an alarm will be issued, and the clothes treatment device will be switched from the running state to the off state, so as to remind the user to pay attention in time, and avoid the problem of overflowing the sink caused by the continuous operation of the clothes treatment device.

Step 602: Based on the water full alarm signal, obtain the number of times the drain pump alternately stops and runs during the intermittent operation.

Step 603: Control the drainage pump to perform intermittent operation according to the alternate times.
