[0028] Embodiments of the present invention are described in detail below, 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 invention, and should not be construed as limiting the present invention.

[0029] The following describes an air conditioning device and a drainage control method and device thereof, and a storage medium according to an embodiment of the present invention with reference to the accompanying drawings.

[0030] In a drainage control method for air conditioning equipment proposed by the present invention, Figure 1 As shown, 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 arranged corresponding to the outdoor water tank 102, and the spray pump 104 is arranged 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 arranged on the wall of the outdoor unit.

[0031] More specifically, refer to Figure 1 It can be seen that the air conditioning device 100 includes an outdoor unit and an indoor unit, wherein the outdoor unit also includes a condenser 109, and the indoor unit includes an evaporator 110. The outdoor water storage tank 102 is arranged below the condenser 109 to facilitate the collection of condensed water generated by the condenser 109 during operation. When it rains outdoors, the outdoor water storage tank 102 will also collect some rainwater. The indoor water storage tank 101 is also correspondingly arranged below the evaporator 110 to facilitate the collection of condensed water generated by the evaporator 110 during operation. It can be understood that the indoor unit and the outdoor unit are also respectively provided with an external fan 111 and an internal fan 112 to improve the air conditioning effect.

[0032] Figure 2 It is a flow chart of a drainage control method of an air conditioning device according to one embodiment of the present invention.

[0033] like Figure 2As shown, the drainage control method of the air conditioning equipment in this embodiment includes the following steps:

[0034] 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, control the drainage pump to operate at a first preset frequency to drain the water in the outdoor water storage tank into the indoor water storage tank for water storage.

[0035] Specifically, combined Figure 1 This embodiment is described. First, the water level switch involved in this embodiment has the function of automatically generating 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 water pump, may also be included. When water accumulates in the outdoor water storage 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 discharge the water in the outdoor water storage tank 102 into the indoor water storage tank 102. When the water level in the indoor water storage tank 102 reaches the water level of the first indoor water level switch 105, the spray pump 104 can be controlled to discharge the water in the indoor water storage tank 101 to the outdoors.

[0036] 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 drainage pump 103 can be controlled to work at the first preset frequency. For example, during the heating process, water will accumulate in the outdoor water tank 102. When the 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 drainage 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 drained outdoors through the spray pump 104 later.

[0037] The first preset frequency in this embodiment can be to shut down for 10 seconds if there is no work for 50 seconds. That is to say, when the drain 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 drain pump 103 from working for a long time and increase the working life of the drain pump 103.

[0038] 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 continue working at a second preset frequency for a second preset time to discharge the water in the indoor water tank to the outside.

[0039] Specifically, when the drainage pump 103 is discharging water from the outdoor water storage tank 102 to the indoor water storage tank 101, the water level in the outdoor water storage tank 102 will normally become lower and lower, and in this embodiment, it can be set that during normal operation, the drainage pump 103 discharges water from the outdoor water storage tank 102 to the indoor water storage tank 101, and when the first indoor water level switch 107 of the indoor water storage tank 101 is triggered, the first outdoor water level switch 105 of the outdoor water storage tank 102 will no longer be triggered. In this embodiment, if the first indoor water level switch 107 has been triggered, and the second outdoor water level switch 106 is still in the triggered state within the first preset time, it means that although the drainage pump 103 is currently discharging water from the outdoor water storage tank 102 to the indoor water storage tank 101, the water in the outdoor water storage tank 102 is not decreasing, so it can be determined that it is currently raining weather. The first preset time in this embodiment can be a relatively short time, for example, it can be 10 seconds, 30 seconds, 2 minutes, 5 minutes, and can be determined according to the specific volume of the outdoor water storage tank 102. In rainy weather, the spray pump 104 can be controlled to work continuously for a second preset time at a second preset frequency, wherein the second preset frequency can be 30 seconds of work and 10 seconds of shutdown, and the second preset time can be 20 minutes, that is, when it is determined to be rainy weather, the spray pump 104 can be controlled to shut down for 10 seconds every 30 seconds of work within 20 minutes. Within the second preset time, due to rainy weather, the first outdoor water level switch 105 or the second outdoor water level switch 106 will always be in a triggered state, so it is not necessary to perform specific repeated detection on it, simplifying the control logic.

[0040] 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 be set according to actual usage and are not specifically limited here.

[0041] In this embodiment, the drainage control method includes: when controlling the spray pump to operate, turning off the drainage pump, and when controlling the drainage pump to operate, turning off the spray pump.

[0042] Specifically, when the drainage pump 103 drains 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 drains 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.

[0043] It can be understood 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 the conventional control logic, the drainage pump 103 and the spray pump 104 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.

[0044] In some embodiments of the present invention, Figure 3 As shown, when the spray pump operates at the second preset frequency, the drainage control method further includes:

[0045] S301, obtaining the number of times the spray pump operates and the duration for which the first indoor water level switch is continuously triggered.

[0046] Specifically, combined Figure 1 This embodiment is described. During the process of the spray pump 104 working at the second preset frequency, the number of times the spray pump 104 runs can be obtained, wherein the time for each operation of the spray pump 104 can be understood as one working time plus one shut-down time, wherein one working time can be 30 seconds and one shut-down time can be 10 seconds. This embodiment also obtains the time when the first indoor water level switch 107 is continuously triggered. It can be understood that when the first indoor water level switch 107 detects that the water level in the indoor water storage tank 101 reaches the position where the first indoor water level switch 107 is located, it means that the first indoor water level switch 107 is triggered, thereby starting to count to obtain the time when the first indoor water level switch 107 is continuously triggered. When the water level in the indoor water storage tank 101 is lower than the position where the first indoor water level switch 107 is located, it means that the current first indoor water level switch 107 has not been triggered, so the timing can be reset to zero and the timing can be restarted when it is triggered next time.

[0047] 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.

[0048] Specifically, after obtaining the number of times the spray pump 104 has been operated and the time the first indoor water level switch 107 has been continuously triggered, a judgment is made. If the number of times the spray pump 104 has been operated is greater than or equal to the first preset number of times, or the time the first indoor water level switch 107 has been continuously triggered is greater than or equal to the third preset time, the spray pump 104 can be turned off. It can be understood that the first preset number of times in this embodiment can be 30 times, and the third preset time can be 10 minutes. In the normal working process, the spray pump 104 has worked 30 times, and the water in the indoor water storage tank 101 will be drained or at least will not continuously trigger the first indoor water level switch 107 for 10 minutes. If the spray pump 104 has been continuously operated 30 times or the first indoor water level switch 107 has been continuously triggered for 10 minutes, it can be determined that the current spray pump 104 has a fault and cannot normally drain the water in the indoor water storage tank 101 to the outside. Therefore, the spray pump 104 is turned off first, and a fault alarm can be issued, wherein the alarm content may include a fault in the spray pump 104 and / or a fault in the spray head 108.

[0049] In some embodiments of the present invention, the drainage control method further includes: when a shutdown control signal of the spray pump is obtained, controlling the spray pump to continue running for a fourth preset time and then shutting down the spray pump.

[0050] 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 obtain 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, first, after receiving the shutdown control signal of the spray pump, the air conditioner 100 further controls the spray pump to continue running for a fourth preset time, 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 discharged, so that the water will not freeze in the spray head 108 and / or the water pipe, causing the spray pump 104 to fail to work normally when it is started next time.

[0051] Optionally, the fourth preset time in this embodiment may be one operation time of the spray pump 104, and the operation time may be 30 seconds. Further, in some embodiments, during the last preset time of the operation time of the spray pump 104, the spray pump 104 may be controlled to discharge air to the outside to reduce the risk of freezing and clogging of the spray head. Specifically, during the operation time of the spray pump 104, the first two-thirds of the time may be used for normal drainage, and the last one-third of the time may be used for blowing air to the outside.

[0052] In some embodiments of the present invention, 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, controlling the spray pump to operate at a second preset frequency to discharge the water in the indoor water tank to the outside.

[0053] Specifically, when the drainage pump 103 drains the water in the outdoor water storage tank 102 to the indoor water storage tank 101, that is, when the indoor water storage tank 101 is storing water, the water in the outdoor water storage tank 102 will become less and less, while the water in the indoor water storage tank 101 will become more and more. At this time, if the first indoor water level switch 107 is not triggered, but the first outdoor water level switch 105 changes from the triggered state to the untriggered state, it means that the water in the outdoor water storage tank 102 is already less, while the water in the indoor water storage tank 101 is already stored more, so the spray pump 104 can be controlled to work to drain the water in the indoor water storage tank 101 to the outside. 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.

[0054] In this embodiment, if Figure 4 As shown, the drainage control method of the air conditioning equipment also includes:

[0055] S401: If the first indoor water level switch is not triggered and the first outdoor water level switch is triggered, then the triggering state of the second outdoor water level switch is detected after a fifth preset time.

[0056] S402, when the second outdoor water level switch is triggered, an outdoor high water level alarm message is issued.

[0057] 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, and therefore an outdoor high water level alarm message can be issued.

[0058] It should be noted that the fifth preset time in this embodiment may 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 may be a voice alarm or a light alarm.

[0059] S403, when the second outdoor water level switch is not triggered, obtaining the number of times the drainage pump is operated and the time for which the first outdoor water level switch is continuously triggered.

[0060] Specifically, if the second outdoor water level switch 106 is not triggered after the fifth preset time, the number of times the drainage pump 103 is run and the time when the first outdoor water level switch 105 is continuously triggered are further obtained. In the process of the drainage pump 103 running at the first preset frequency, the time when the drainage pump 103 is not run once can be understood as one working time plus one shutdown time, wherein one working time can be 50 seconds and one shutdown time can be 10 seconds. This embodiment also obtains the time when the first outdoor water level switch 105 is 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 where the first outdoor water level switch 105 is located, it means that the first outdoor water level switch 105 is triggered, so the timing starts to obtain the time when the first outdoor water level switch 105 is continuously triggered. When the water level in the outdoor water storage tank 102 is lower than the position where the first outdoor water level switch 105 is located, it means that the current first outdoor water level switch 105 has not been triggered, so the timing can be reset and the timing can be restarted when it is triggered next time.

[0061] 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.

[0062] Specifically, after obtaining the number of times the drain pump 103 is operated and the time the first outdoor water level switch 105 is continuously triggered, a judgment is made. If the number of times the drain pump 103 is operated is greater than or equal to the second preset number of times, or the time the first outdoor water level switch 105 is continuously triggered is greater than or equal to the sixth preset time, the drain pump 103 can be turned off. It can be understood that the second preset number of times in this embodiment can be 30 times, and the sixth preset time can be 15 minutes. In the normal working process, if the drain pump 103 works 30 times, the water in the outdoor water storage tank 102 will be drained or at least the first outdoor water level switch 105 will not be continuously triggered for 15 minutes. If the drain pump 103 works continuously for 30 times or the first outdoor water level switch 105 is continuously triggered for 15 minutes, it can be determined that the current drain pump 103 has a fault and cannot normally drain the water in the outdoor water storage tank 102 to the indoor water storage tank 101. Therefore, the drain pump 103 is turned off first, and a drainage fault alarm can be issued.

[0063] In some embodiments of the present invention, the air-conditioning equipment also includes an indoor humidification water tank and a humidification water pump, and the humidification water pump is arranged corresponding to the indoor water storage tank. The drainage control method also includes: when the humidification function start instruction of the air-conditioning equipment is obtained, the humidification water pump is controlled to work so as to drain the water in the indoor water storage tank into the indoor humidification water tank.

[0064] Specifically, Figure 1 As shown, the air conditioner 100 also includes an indoor humidification water tank 113 and a humidification water pump 114. The humidification water pump 114 is arranged corresponding to the indoor water storage tank 101, and can pump the water in the indoor water storage tank 101 into the indoor humidification water tank 113. The indoor humidification water tank 113 and the humidification water pump 114 are both arranged in the indoor unit. The air conditioner 100 can obtain the humidification function start instruction issued by the user through the remote control or the wire controller, and then control the humidification water pump 114 to work according to the humidification function start instruction to discharge the water in the indoor water storage tank 101 into the indoor humidification water tank 113 for subsequent humidification operations. 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 indoors by the indoor fan 112 to complete the humidification of the indoor air.

[0065] Optionally, the air conditioner 100 of the present invention may also be provided with a humidity detector 115 for detecting the indoor air humidity to help the user determine whether to start the humidification function. In addition, the indoor water storage tank 101 of the present invention may also be provided with a second indoor water level switch 116, which may replace the first indoor water level switch 107 to complete the above embodiment.

[0066] In summary, the drainage control method of the air-conditioning equipment in the embodiment of the present invention 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.
