[0038] At present, the dehumidifier water tank on the market will issue an alarm when it is full of water to remind the user to clean the water tank in time. The designer of the present application found in the research that when the water full alarm is issued, there will be residual condensate in the evaporator or waterway, and when the user takes out the water tank, the residual water will still flow out through the water outlet hole and fall to the chassis. In addition, there may be frost during use, and the water full alarm cannot determine the frost, and the water formed during the defrosting process will still flow out through the water outlet hole and fall to the chassis. The above-mentioned situations will affect the user experience.

[0039] Therefore, the embodiment of the present application provides a dehumidifier water tank water full alarm control method, device and dehumidifier, which can control the dehumidifier to delay alarm in the presence of frost or no frost on the evaporator, so as to ensure that the water on the evaporator or waterway can completely flow into the water tank, prevent the residual water from flowing out through the water outlet hole after the user takes out the water tank, and improve the user experience.

[0040] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0041] Please refer to Figure 1 The dehumidifier water tank water full alarm control method provided by the embodiment of the present application is applied to a dehumidifier, which can be a household dehumidifier or the like. The dehumidifier water tank water full alarm control method comprises the following steps:

[0042] Step S100, in the case that the water tank of the dehumidifier reaches a water full state, it is judged whether the evaporator is frosted.

[0043] In step S100, the water full state of the water tank can be detected by the water level sensor arranged in the water tank, and when it is detected that the water in the water tank reaches the water full level, it can be considered that the water tank reaches the water full state. At this time, it is judged whether the evaporator is frosted.

[0044] Step S200, according to the frost judgment result, the dehumidifier is controlled to delay issuing a water full alarm signal.

[0045] In step S200, the frost judgment result includes the presence of frost on the evaporator and the absence of frost on the evaporator, and according to the different frost judgment results, the dehumidifier is controlled accordingly, and the dehumidifier is controlled to delay issuing a water full alarm signal.

[0046] The dehumidifier water tank full alarm control method provided by the embodiment of the present application controls the dehumidifier to delay sending a water tank full alarm signal according to the result of the frosting determination of the evaporator when the water tank reaches the water full state. The control method controls the dehumidifier when the evaporator has frosting or no frosting, and can ensure that the water on the evaporator or water path can completely flow into the water tank by delaying sending the water tank full alarm signal, thereby preventing the residual water from flowing out of the water tank through the water outlet hole after the user takes out the water tank, and improving the user experience.

[0047] It should be noted that in the related art, the water tank full alarm is performed when the water tank reaches the water full state, without considering the frosting of the evaporator, and after the water tank full alarm, the residual water may still flow to the bottom plate through the water outlet hole regardless of whether the evaporator is frosted. In the embodiment of the present application, the frosting of the evaporator is determined when the water tank reaches the water full state, the frosting of the evaporator is considered, and the dehumidifier is controlled according to the different results of the frosting determination, and the dehumidifier is controlled to delay sending the water tank full alarm signal, to ensure that the residual water on the evaporator or water path or the water formed during the defrosting process flows into the water tank.

[0048] In addition, it should be noted that in order to ensure that the water tank can still receive the residual water on the evaporator or water path or the water formed during the defrosting process after the water tank reaches the water full state, the water tank has sufficient space above the water full level to ensure that the residual water or the water formed during the defrosting process falls into the water tank during the delay process, and does not overflow from the water tank.

[0049] Please refer to Figure 2 In order to improve the accuracy of the frosting determination of the evaporator, the optional embodiment of the present application can include the following sub-steps S110-S130.

[0050] In the sub-step S110, it is determined whether the evaporator coil temperature is greater than or equal to 0℃.

[0051] In the sub-step S110, the evaporator coil temperature is obtained by detecting the temperature sensor arranged on the evaporator. When the water tank reaches the water full state, the frosting determination is performed first, and it is determined whether the evaporator coil temperature is greater than or equal to 0℃, so as to determine whether the evaporator is frosted, thereby improving the accuracy of the frosting determination of the evaporator.

[0052] In the sub-step S120, if the evaporator coil temperature is greater than or equal to 0℃, it is determined that the evaporator has no frosting.

[0053] In the sub-step S120, if the evaporator coil temperature is greater than or equal to 0℃, the evaporator is not easy to frost, and at this time, it can be considered that the evaporator has no frosting.

[0054] If the evaporator coil temperature is less than 0℃, it is determined that the evaporator has frost.

[0055] In the sub-step S130, if the evaporator coil temperature is less than 0℃, i.e. the evaporator coil temperature is less than the frost temperature, the evaporator is prone to frost, and it is considered that the evaporator has frost.

[0056] Please refer to Figure 3 In addition, after the frost determination, in order to better control the dehumidifier according to the frost result, in the optional embodiment of the present application, the step S200 can include the following sub-step S210 to sub-step S220.

[0057] In the sub-step S210, if it is determined that the evaporator has no frost, it is considered that this is a normal water full delay alarm condition, and the dehumidifier is controlled to delay the first water full alarm delay time to send a water full alarm signal. The first water full alarm delay time is represented by t1, which can be set according to actual needs, for example, the value range of t1 can be changed according to the size of the evaporator and the environmental humidity. In this embodiment, the value range of the first water full alarm delay time t1 is optionally 3min < t1 < 10min. In this way, it can be ensured that the condensate water generated by the low temperature state of the evaporator during the delay process is completely dripped into the water tank.

[0058] Please refer to In addition, in order to further improve the user experience, the sub-step S210 can further include the following sub-step S211 and sub-step S212.

[0059] Figure 4

[0060] In the sub-step S211, during the delay of the first water full alarm delay time of the dehumidifier, the compressor is controlled to stop running.

[0061] In the sub-step S211, during the delay of the first water full alarm delay time of the dehumidifier, in order to prevent the evaporator from continuing to generate more condensate water, the compressor is controlled to stop running during the delay process, at this time the delay process does not refrigerate and no more condensate water is generated, further ensuring that the condensate water generated by the low temperature state of the evaporator during the delay process is completely dripped into the water tank.

[0062] In the sub-step S212, during the delay of the first water full alarm delay time of the dehumidifier, the fan is controlled to run.

[0063] ​In the sub-step S212, during the delay of the first water full alarm delay time, the fan can be controlled to operate, so that the water can flow to the water tank more quickly, and the wind can also take away part of the water vapor, and the user can not think that the delay of the water full alarm is a machine stop fault, and the use experience of the user can be improved.

[0064] Please refer to Figure 3 In the sub-step S220, if it is determined that the evaporator has frost, the air conditioner is controlled to delay a second water full alarm delay time to send a water full alarm signal, and the second water full alarm delay time is greater than the first water full alarm delay time.

[0065] In the sub-step S220, if it is determined that the evaporator has frost, the air conditioner is controlled to delay a second water full alarm delay time to send a water full alarm signal, and the second water full alarm delay time is greater than the first water full alarm delay time.

[0066] The second water full alarm delay time satisfies the following relationship:

[0067]

[0068] Wherein, t represents the second water full alarm delay time, a represents the delay correction coefficient, C represents the basic extension alarm time, and a<0, C>t1, t1 represents the first water full alarm delay time, T represents the evaporator coil temperature when the frost judgment is performed, and T<0℃.

[0069] It should be noted that the delay correction coefficient a and the basic extension alarm time C are both preset values set according to actual needs. Since the evaporator coil temperature T<0℃ and the delay correction coefficient a<0, t is a positive value, and as the evaporator coil temperature T decreases (the absolute value of T increases), the greater the value of t is.

[0070] In this way, the setting of the second water full alarm delay time can ensure that the delay is long enough to ensure that the remaining condensate water or water generated by defrosting can flow into the water tank. Moreover, the water full alarm delay time can be controlled according to the detection of different evaporator coil temperatures below 0℃.

[0071] Please refer to Figure 5 ​In addition, in order to defrost the dehumidifier effectively, in the optional embodiment of the present application, the sub-step S220 can further include the following sub-steps S221-S222.

[0072] In the sub-step S221, if it is determined that the evaporator has frost, the dehumidifier is controlled to defrost, and the defrosting time is equal to

[0073] In the sub-step S221, if it is determined that the evaporator has frost, the dehumidifier is controlled to defrost, and the defrosting time is set to be equal to In this way, the defrosting time can be increased with the decrease of the evaporator coil temperature T (T<0℃), that is, the lower the evaporator coil temperature T, the more the frost, the longer the defrosting time, and the longer the water full alarm delay time in the frost condition.

[0074] In the sub-step S222, after the dehumidifier is defrosted, the dehumidifier is controlled to send a water full alarm signal after the basic alarm time is delayed.

[0075] In the sub-step S222, after the dehumidifier is defrosted for , the basic alarm time is further delayed to ensure that the water generated after defrosting can flow into the water tank. The basic alarm time C is greater than the first water full alarm delay time t1, so that the water after defrosting can be effectively ensured to flow into the water tank. The water full alarm signal is sent after the basic alarm time is delayed.

[0076] In summary, the dehumidifier water tank water full alarm control method provided by the embodiment of the present application can accurately determine the frost condition and effectively defrost after the water tank reaches the water full state, and then accurately determine whether there is still condensed water in the flow channel after the water full state, intelligently control the water full delay alarm according to the evaporator coil temperature condition, and improve the overall use effect.
