[0031] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0032] The following describes an air-conditioning device, a drainage control method and device thereof, and a storage medium according to an embodiment of the present disclosure with reference to the accompanying drawings.

[0033] In a drainage control method for an air-conditioning equipment proposed in the present disclosure, as shown in Figure 1, the air-conditioning equipment 100 includes an indoor water tank 101, an outdoor water tank 102, a drainage pump 103 and a spray pump 104. The drainage pump 103 is set corresponding to the outdoor water tank 102, and the spray pump 104 is set corresponding to the indoor water tank 101. The outdoor water tank 102 is provided with a first outdoor water level switch 105 and a second outdoor water level switch 106, and the indoor water tank 101 is provided with a first indoor water level switch 107. The drainage pump 103 can pump water in the outdoor water tank 102 into the indoor water tank 101, and then discharge the water in the indoor water tank 101 to the outdoors through the spray pump 104, wherein the spray head 108 of the spray pump 104 can be set on the wall of the outdoor unit.

[0034] More specifically, referring to FIG1 , air conditioning equipment 100 includes an outdoor unit and an indoor unit. The outdoor unit includes a condenser 109, and the indoor unit includes an evaporator 110. An outdoor water storage tank 102 is located below condenser 109 to collect condensed water generated by condenser 109 during operation. When it rains outdoors, outdoor water storage tank 102 also collects some rainwater. Indoor water storage tank 101 is also located below evaporator 110 to collect condensed water generated by evaporator 110 during operation. It is understood that the indoor and outdoor units are also equipped with an outdoor fan 111 and an indoor fan 112, respectively, to enhance the air conditioning effect.

[0035] FIG2 is a flow chart of a drainage control method for an air-conditioning device according to an embodiment of the present disclosure.

[0036] As shown in FIG2 , the drainage control method of the air-conditioning equipment in this embodiment includes the following steps:

[0037] S101, when the first indoor water level switch is not triggered and the first outdoor water level switch or the second outdoor water level switch is triggered, controlling the drainage pump to operate at a first preset frequency to drain water in the outdoor water tank into the indoor water tank for storage.

[0038] Specifically, this embodiment is described in conjunction with FIG1 . First, the water level switch involved in this embodiment is used to automatically generate a water level signal when water is detected, so that the controller can use the water level signal to control the corresponding water pump, wherein the water pump refers to the drainage pump 103 and the spray pump 104. In some embodiments, other pump bodies, such as a humidification pump, may also be included. When water accumulates in the outdoor water tank 102 and the water level of the accumulated water reaches the water level of the first outdoor water level switch 105, the drainage pump 103 can be controlled to drain the water in the outdoor water tank 102 into the indoor water tank 102. When the water level in the indoor water tank 102 reaches the water level of the first indoor water level switch 105, the spray pump 104 can be controlled to drain the water in the indoor water tank 101 to the outside.

[0039] More specifically, if the first indoor water level switch 105 is not triggered, and the first outdoor water level switch 105 or the second outdoor water level switch 106 is triggered at this time, the drain pump 103 can be controlled to operate at a first preset frequency. For example, during the heating process, water accumulates in the outdoor water tank 102. When this accumulated water triggers the first outdoor water level switch 105 or the second outdoor water level switch 106, and the first indoor water level switch 107 is not triggered, the drain pump 103 can be controlled to drain the water in the outdoor water tank 102 to the indoor water tank 101, so that the water in the indoor water tank 101 can be subsequently drained to the outside via the spray pump 104.

[0040] The first preset frequency in this embodiment can be to shut down for 10 seconds if it does not work for 50 seconds. That is to say, when the drainage pump 103 is in working state, its specific working method is to work continuously for 50 seconds and then shut down for 10 seconds. Working at this frequency can avoid the drainage pump 103 from working for a long time and improve the working life of the drainage pump 103.

[0041] S102, during the water storage process of the indoor water tank, if the first indoor water level switch is triggered and the second outdoor water level switch is still triggered within the first preset time, it is determined to be rainy weather, and the spray pump is controlled to operate continuously at a second preset frequency for a second preset time to discharge the water in the indoor water tank to the outside.

[0042] Specifically, during the process of drain pump 103 draining water from outdoor water tank 102 to indoor water tank 101, the water level in outdoor water tank 102 will normally decrease. In this embodiment, it is configured that during normal operation, when drain pump 103 drains water from outdoor water tank 102 to indoor water tank 101, and when first indoor water level switch 107 of indoor water tank 101 is triggered, first outdoor water level switch 105 of outdoor water tank 102 will no longer be triggered. In this embodiment, if first indoor water level switch 107 is triggered but second outdoor water level switch 106 remains triggered within the first preset time, this indicates that although drain pump 103 is draining water from outdoor water tank 102 to indoor water tank 101, the water level in outdoor water tank 102 is not decreasing, and therefore it can be determined that it is currently raining. In this embodiment, the first preset time can be a relatively short time, such as 10 seconds, 30 seconds, 2 minutes, or 5 minutes, and can be determined based on the specific volume of the outdoor water storage tank 102. In rainy weather, the spray pump 104 can be controlled to operate continuously for a second preset time at a second preset frequency, wherein the second preset frequency can be 30 seconds on and 10 seconds off, and the second preset time can be 20 minutes. In other words, when it is determined to be rainy weather, the spray pump 104 can be controlled to operate for 30 seconds and then off for 10 seconds within 20 minutes. During the second preset time, due to the rainy weather, the first outdoor water level switch 105 or the second outdoor water level switch 106 will remain in a triggered state, so repeated testing can be omitted, simplifying the control logic.

[0043] It should be noted that the first preset frequency, the second preset frequency, the first preset time, and the second preset time in this embodiment can all be set according to actual usage and are not specifically limited here.

[0044] In this embodiment, the drainage control method includes: turning off the drainage pump when controlling the spray pump to operate, and turning off the spray pump when controlling the drainage pump to operate.

[0045] Specifically, when the drainage pump 103 discharges the water in the outdoor water tank 102 to the indoor water tank 101, the spray pump 104 is turned off, that is, the spray pump 104 is controlled not to work, and when the spray pump 104 discharges the water in the indoor water tank 101 to the outside through the spray head 108, the drainage pump 103 is turned off, that is, the drainage pump 103 is controlled not to work.

[0046] It is understandable that controlling the drainage pump 103 and the spray pump 104 to work at different times can improve the service life of the water pump. Specifically, in rainy weather, the water level switch in the outdoor water tank 102 and the water level switch in the indoor water tank 101 are continuously in the triggered state. According to conventional control logic, the drainage pump 103 and the spray pump 104 both need to be in the on state. However, due to rain, it is very likely that the drainage pump 103 and the spray pump 104 will run for a long time depending on the duration of the rain, thereby reducing the service life of the water pump. Therefore, this embodiment limits the drainage pump 103 and the spray pump 104 to work at different times.

[0047] In some embodiments of the present disclosure, as shown in FIG3 , when the spray pump operates at the second preset frequency, the drainage control method further includes:

[0048] S301, obtaining the number of times the spray pump has been operated and the duration for which the first indoor water level switch has been continuously triggered.

[0049] Specifically, in conjunction with FIG1 , this embodiment is described. During the operation of the spray pump 104 at the second preset frequency, the number of times the spray pump 104 has operated can be obtained. The duration of each operation of the spray pump 104 can be understood as one operating time plus one shutoff time. The operating time can be 30 seconds, and the shutoff time can be 10 seconds. This embodiment also obtains the duration of the first indoor water level switch 107 being continuously triggered. It is understood that when the first indoor water level switch 107 detects that the water level in the indoor water tank 101 reaches the position at which the first indoor water level switch 107 is located, it indicates that the first indoor water level switch 107 has been triggered, thereby starting a timer to obtain the duration of the first indoor water level switch 107 being continuously triggered. When the water level in the indoor water tank 101 falls below the position at which the first indoor water level switch 107 is located, it indicates that the first indoor water level switch 107 is no longer triggered. Therefore, the timer can be reset to zero and restarted upon the next triggering.

[0050] S302: When the spray pump operates for a number of times greater than or equal to a first preset number of times, or when the first indoor water level switch is continuously triggered for a time greater than or equal to a third preset time, turn off the spray pump and determine that the spray pump is in a fault state.

[0051] Specifically, after obtaining the number of times the spray pump 104 has operated and the duration for which the first indoor water level switch 107 has been continuously triggered, a determination is made. If the number of times the spray pump 104 has operated is greater than or equal to a first preset number of times, or the duration for which the first indoor water level switch 107 has been continuously triggered is greater than or equal to a third preset time, the spray pump 104 may be shut down. It is understood that in this embodiment, the first preset number of times may be 30 times, and the third preset time may be 10 minutes. During normal operation, if the spray pump 104 has operated 30 times, the water in the indoor water tank 101 will be completely drained, or at least the first indoor water level switch 107 will not be continuously triggered for 10 minutes. If the spray pump 104 has operated continuously 30 times or the first indoor water level switch 107 has been continuously triggered for 10 minutes, it is determined that the spray pump 104 is faulty and cannot properly drain the water in the indoor water tank 101 to the outside. Therefore, the spray pump 104 is shut down and a fault alarm may be issued, wherein the alarm content may include a fault in the spray pump 104 and / or a fault in the spray head 108.

[0052] In some embodiments of the present disclosure, the drainage control method further includes: when a shutdown control signal of the spray pump is obtained, controlling the spray pump to continue operating for a fourth preset time and then shutting down the spray pump.

[0053] Specifically, during the operation of the spray pump 104, the user can control the spray pump 104 or the air conditioner 100 to stop working at any time through a control device such as a remote controller or a wired controller. It is understandable that the air conditioner 100 will also receive a shutdown control signal of the spray pump 104 when it stops working, so as to further control the spray pump 104 to shut down. In the process of controlling the spray pump 104 to shut down, the air conditioner 100 first controls the spray pump to continue running for a fourth preset time after receiving the shutdown control signal of the spray pump, and then shuts down the spray pump 104 to ensure that the water in the water pipe connecting the spray head 108 and the spray pump 104 can be drained, so that the water does not freeze in the spray head 108 and / or the water pipe, causing the spray pump 104 to malfunction when it is next started.

[0054] Optionally, the fourth preset time in this embodiment may be the operating time of the spray pump 104, which may be 30 seconds. Furthermore, in some embodiments, during the last preset time of the operating time of the spray pump 104, the spray pump 104 may be controlled to exhaust air to the outside to reduce the risk of the spray head freezing and clogging. Specifically, the spray pump 104 may be operated to drain air normally for the first two-thirds of the operating time, and to exhaust air to the outside for the last one-third of the operating time.

[0055] In some embodiments of the present disclosure, the drainage control method includes: during the water storage process of the indoor water tank, if the first indoor water level switch is not triggered and the first outdoor water level switch changes from a triggered state to an untriggered state, then controlling the spray pump to operate at a second preset frequency to discharge the water in the indoor water tank to the outside.

[0056] Specifically, as the drain pump 103 drains water from the outdoor water tank 102 to the indoor water tank 101, i.e., as the indoor water tank 101 accumulates water, the water in the outdoor water tank 102 decreases, while the water in the indoor water tank 101 increases. At this time, if the first indoor water level switch 107 is not triggered, but the first outdoor water level switch 105 changes from a triggered state to an untriggered state, this indicates that the water in the outdoor water tank 102 is already relatively low, while the water in the indoor water tank 101 is already relatively high. Therefore, the spray pump 104 can be controlled to operate to drain the water in the indoor water tank 101 outdoors. More specifically, in this embodiment, the spray pump 104 is still controlled to operate at the second preset frequency, wherein the second preset frequency has been described in detail in the above embodiment and will not be repeated here.

[0057] In this embodiment, as shown in FIG4 , the drainage control method of the air conditioning equipment further includes:

[0058] S401: If the first indoor water level switch is not triggered and the first outdoor water level switch is triggered, then detect the triggering state of the second outdoor water level switch after a fifth preset time.

[0059] S402: When the second outdoor water level switch is triggered, an outdoor high water level alarm message is issued.

[0060] Specifically, when it is determined that it is not raining weather at present, and the drainage pump 103 drains water from the outdoor water tank 102 to the indoor water tank 101, under normal circumstances, the water in the outdoor water tank 102 will become less and less, while the water in the indoor water tank 101 will become more and more. If the first indoor water level switch 107 is not triggered and the first outdoor water level switch 105 is triggered, timing is performed, and after the timing time reaches the fifth preset time, it is further detected that the second outdoor water level switch 106 is in a triggered state, which indicates that the water in the current outdoor water tank 102 is increasing, so an outdoor high water level alarm message can be issued.

[0061] It should be noted that the fifth preset time in this embodiment can be 5 minutes, and the fifth preset time is greater than the first preset time. In addition, the outdoor high water level alarm information in this embodiment can be a voice alarm or a light alarm.

[0062] S403: When the second outdoor water level switch is not triggered, obtain the number of times the drainage pump has been run and the time for which the first outdoor water level switch has been continuously triggered.

[0063] Specifically, if the second outdoor water level switch 106 is not triggered after the fifth preset time, the number of times the drain pump 103 has run and the duration of the first outdoor water level switch 105 being continuously triggered are further obtained. During the process of the drain pump 103 operating at the first preset frequency, the time during which the drain pump 103 has not run once can be understood as one operating time plus one shutdown time, wherein one operating time can be 50 seconds and one shutdown time can be 10 seconds. This embodiment also obtains the duration of the first outdoor water level switch 105 being continuously triggered. It can be understood that when the first outdoor water level switch 105 detects that the water level in the outdoor water storage tank 102 reaches the position of the first outdoor water level switch 105, it indicates that the first outdoor water level switch 105 has been triggered, and thus a timer is started to obtain the duration of the first outdoor water level switch 105 being continuously triggered. When the water level in the outdoor water storage tank 102 is lower than the position of the first outdoor water level switch 105, it indicates that the first outdoor water level switch 105 is no longer triggered. Therefore, the timer can be reset to zero and restarted when it is next triggered.

[0064] S404: When the drain pump runs for a number of times greater than or equal to a second preset number of times, or when the first outdoor water level switch is continuously triggered for a time greater than or equal to a sixth preset time, turn off the drain pump and determine that the drain pump is in a fault state.

[0065] Specifically, after obtaining the number of times the drain pump 103 has operated and the duration for which the first outdoor water level switch 105 has been continuously triggered, a determination is made. If the number of times the drain pump 103 has operated is greater than or equal to a second preset number of times, or the duration for which the first outdoor water level switch 105 has been continuously triggered is greater than or equal to a sixth preset time, the drain pump 103 may be shut down. It is understood that in this embodiment, the second preset number of times may be 30 times, and the sixth preset time may be 15 minutes. During normal operation, if the drain pump 103 has operated 30 times, the water in the outdoor water tank 102 will be completely drained, or at least the first outdoor water level switch 105 will not be continuously triggered for 15 minutes. If the drain pump 103 has operated 30 times or the first outdoor water level switch 105 has been continuously triggered for 15 minutes, it is determined that the drain pump 103 is faulty and cannot properly drain the water in the outdoor water tank 102 to the indoor water tank 101. Therefore, the drain pump 103 is shut down and a drainage fault alarm may be issued.

[0066] In some embodiments of the present disclosure, the air-conditioning equipment also includes an indoor humidification water tank and a humidification water pump. The humidification water pump is set corresponding to the indoor water storage tank. The drainage control method also includes: when the humidification function start-up instruction of the air-conditioning equipment is obtained, the humidification water pump is controlled to work to drain the water in the indoor water storage tank into the indoor humidification water tank.

[0067] Specifically, as shown in FIG1 , the air conditioner 100 further includes an indoor humidification water tank 113 and a humidification water pump 114. The humidification water pump 114 is provided in correspondence with the indoor water storage tank 101 and can pump water from the indoor water storage tank 101 into the indoor humidification water tank 113. Both the indoor humidification water tank 113 and the humidification water pump 114 are provided in the indoor unit. The air conditioner 100 can receive a humidification function activation command issued by the user via a remote control or wired controller, and then control the humidification water pump 114 to operate according to the humidification function activation command, thereby draining the water from the indoor water storage tank 101 into the indoor humidification water tank 113 for subsequent humidification operation. More specifically, the bottom of the indoor humidification water tank 113 in this embodiment is hollowed out, and the indoor humidification water tank 113 is arranged at the upper end of the evaporator 110, so that the water in the indoor humidification water tank 113 can pass through the evaporator 110 and then be blown into the room by the indoor fan 112 to complete the humidification of the indoor air.

[0068] Optionally, the air conditioner 100 of the present disclosure may further include a humidity detector 115 for detecting indoor air humidity to help the user determine whether to activate the humidification function. Furthermore, the indoor water storage tank 101 of the present disclosure may further include a second indoor water level switch 116, which may replace the first indoor water level switch 107 to complete the above-described embodiment.

[0069] In summary, the drainage control method of the air-conditioning equipment in the embodiment of the present disclosure can reduce the operating time of the water pump, increase the service life of the water pump, while providing the user with a better usage experience, and also ensure that the spray head will not be blocked by freezing, thereby ensuring that the air-conditioning equipment can operate normally.

[0070] Furthermore, the present disclosure proposes a computer-readable storage medium on which a drainage control program for an air-conditioning device is stored.
