Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioner, an operation control method, an operation control device and a storage medium. Background Art

[0002] Air conditioners generally use compressors to circulate refrigerant between heat exchangers to achieve cooling or heating. Condensation water is inevitable during the operation of the air conditioner. For example, when cooling, water vapor in the indoor air will condense into water when it hits the low-temperature indoor heat exchanger. When heating, water vapor in the outdoor air will condense into water or adhere to the outdoor heat exchanger to form frost when it hits the low-temperature outdoor heat exchanger, and turn into water after the air conditioner defrosts.

[0003] At present, when the water pan in the air conditioner collects a lot of condensed water, a water pump is generally used to pump the condensed water to the outdoor unit for treatment, such as spraying the outdoor heat exchanger for cooling or discharging it to the outside for atomization treatment. The water pump of the indoor unit has low noise when pumping water, but it will produce loud noise when pumping air, especially at night, which may affect the user's sleep and seriously affect the user's experience. Summary of the invention

[0006] The indoor water receiving tray is used to collect condensed water;

[0007] The water outlet of the first water pump is connected to the outdoor spray outlet through a water outlet pipe;

[0008] The three-way valve comprises a first inlet connected to the indoor water receiving pan via a first water inlet pipe, a second inlet connected to the outdoors via an air inlet pipe, and a first outlet connected to the water inlet of the first water pump;

[0009] The controller is used to control the conduction state of the three-way valve when the first water pump is working, so as to reduce the noise of the first water pump when pumping water.

[0010] The air conditioner provided according to the embodiment of the present invention has at least the following beneficial effects: by arranging a three-way valve upstream of the water inlet of the first water pump, and the two inlets of the three-way valve are respectively connected to the indoor water receiving tray and the outdoor, when the three-way valve is connected to the first inlet and the first outlet, the first water pump can extract the condensed water collected in the indoor water receiving tray through the first water inlet pipe and transport it to the outdoor spray outlet through the water outlet pipe, thereby atomizing and consuming the condensed water; in addition, when the water in the indoor water receiving tray is completely extracted, air will be extracted at the first water inlet pipe, causing the indoor unit of the air conditioner to generate a large noise, affecting the user experience; the three-way valve can be controlled by the controller to switch to connecting the second inlet and the first outlet, so that the water inlet of the first water pump is connected to the outdoor through the air inlet pipe, thereby transferring the location of extracting air to the outdoor, that is, transferring the location of generating noise to the outdoor, thereby reducing the noise of the first water pump when pumping water and improving the user experience.

[0011] The air conditioner provided according to some embodiments of the present invention further includes an outdoor water receiving pan for collecting condensed water and a second water pump for pumping condensed water in the outdoor water receiving pan to the indoor water receiving pan.

[0013] According to some embodiments of the air conditioner provided by the present invention, a temperature sensor is provided inside the outdoor water receiving tray.

[0014] According to the air conditioner provided in some embodiments of the present invention, the controller is further used to control the working states of the first water pump and the second water pump according to the liquid level height of the indoor water receiving tray and the liquid level height of the outdoor water receiving tray.

[0015] According to the air conditioner provided in some embodiments of the present invention, when the first water pump is in operation and there is no water in the first water inlet pipe, the three-way valve is controlled to connect the second inlet with the first outlet.

Therefore, when the air conditioner is cooling, the liquid level of the indoor water receiving pan will continue to rise. When the liquid level of the indoor water receiving pan is greater than the first preset height, it means that there is a lot of condensed water and it needs to be consumed. At this time, the three-way valve is controlled to connect the first inlet with the first outlet, and the first water pump is controlled to work, so that the first water pump can extract the condensed water collected in the indoor water receiving pan through the first water inlet pipe and transport it to the outdoor spray port through the water outlet pipe, thereby atomizing. The condensed water is consumed; in addition, when the air conditioner stops operating in the cooling mode, the first water pump is controlled to continue working for the first preset time, so that the condensed water remaining in the indoor water receiving tray, the first water inlet pipe and the water outlet pipe can be cleaned up to avoid the breeding of bacteria or freezing in winter and damaging the pipes and nozzles; in addition, the three-way valve is controlled to connect the second inlet with the first outlet after the second preset time, and the first preset time is greater than the second preset time, that is, in the first half of the period during which the first water pump continues to work, the condensed water remaining in the indoor water receiving tray and the first water inlet pipe is processed, and in the second half of the period during which the first water pump continues to work, the condensed water remaining in the water outlet pipe is processed and the location where the noise is generated is transferred to the outdoors, thereby reducing noise and improving the user experience.

[0039] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0040] In the description of the present invention, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0041] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0042] The embodiments of the present invention provide an air conditioner, an operation control method, an operation control device and a storage medium, which can reduce noise during water pumping and improve the user experience.

[0043] The embodiments of the present invention are further described below in conjunction with the accompanying drawings.

[0044] Reference Figure 1 The first aspect of the present invention provides an air conditioner, including an indoor water receiving tray 110, a first water pump 120, a three-way valve 130 and a controller, wherein: the indoor water receiving tray 110 is used to collect condensed water; the water outlet of the first water pump 120 is connected to the outdoor spray outlet 210 through the water outlet pipe 140; the three-way valve 130 includes a first inlet a connected to the indoor water receiving tray 110 through a first water inlet pipe 150, a second inlet b connected to the outdoor through an air inlet pipe 160, and a first outlet c connected to the water inlet of the first water pump 120; the controller is respectively connected to the first water pump 120 and the three-way valve 130, and the controller is used to control the conduction state of the three-way valve 130 when the first water pump 120 is working, so as to reduce the noise of the first water pump 120 when pumping water.

[0045] According to the air conditioner provided by the embodiment of the present invention, by arranging a three-way valve 130 upstream of the water inlet of the first water pump 120, and the two inlets of the three-way valve 130 are respectively connected to the indoor water receiving tray 110 and the outdoor, when the three-way valve 130 is connected to the first inlet a and the first outlet c, the first water pump 120 can extract the condensed water collected in the indoor water receiving tray 110 through the first water inlet pipe 150 and transport it to the outdoor spray port 210 through the outlet pipe 140, so as to atomize and consume the condensed water; in addition, when the water in the indoor water receiving tray 110 is completely extracted, air will be extracted at the first water inlet pipe 150, causing the indoor unit of the air conditioner to generate a large noise, affecting the user experience; the three-way valve 130 can be controlled by the controller to switch to connect the second inlet b and the first outlet c, so that the water inlet of the first water pump 120 is connected to the outdoor through the air inlet pipe 160, thereby transferring the location of extracting air to the outdoor, that is, transferring the location of generating noise to the outdoor, thereby reducing the noise of the first water pump 120 when pumping water, and improving the user experience.

[0046] Reference Figure 1 In some embodiments of the present invention, the air conditioner further includes an outdoor water receiving pan 220 for collecting condensed water and a second water pump 230 for pumping the condensed water in the outdoor water receiving pan 220 to the indoor water receiving pan 110 .

[0047] It is understandable that the indoor water receiving pan 110 collects condensed water generated by the indoor unit. Generally, when the air conditioner is cooling, water vapor in the indoor air will condense into water when it hits the low-temperature indoor heat exchanger, and then drip into the indoor water receiving pan 110; when the air conditioner is heating, water vapor in the outdoor air will condense into water or adhere to the outdoor heat exchanger to form frost when it hits the low-temperature outdoor heat exchanger, and turn into water after the air conditioner defrosts, and then drip into the outdoor water receiving pan 220. Because the outdoor ambient temperature is generally low when the air conditioner is heating, if the condensed water is not handled in time, it will easily freeze. Therefore, it is necessary to set a second water pump 230 to pump the condensed water in the outdoor water receiving pan 220 to the indoor water receiving pan 110, so that the condensed water generated outdoors is stored in the indoor water receiving pan 110. Refer to Figure 1 The second water pump 230 pumps the condensed water in the outdoor water receiving tray 220 to the indoor water receiving tray 110 through the water pipe 240; in some embodiments, the second water pump 230 is arranged in the outdoor water receiving tray 220, one end of the water pipe 240 is connected to the second water pump 230, and the other end of the water pipe 240 extends to the indoor water receiving tray 110.

[0048] It should be noted that the positions of the indoor water receiving tray 110 and the outdoor water receiving tray 220 can be adjusted according to actual application conditions. For example, in the above embodiment, the indoor water receiving tray 110 and the outdoor water receiving tray 220 can be arranged inside the air conditioner; and in another embodiment, the indoor water receiving tray 110 and the outdoor water receiving tray 220 can also be arranged outside the air conditioner, as long as the condensed water generated by the indoor unit and the outdoor unit can be collected; moreover, in one embodiment, a third water receiving tray, such as a bucket, a water tank or other device, can also be provided. The provision of the third water receiving tray can increase the volume of the original indoor water receiving tray 110 and the outdoor water receiving tray 220, thereby avoiding frequent starting and stopping of the water pump due to the small volume of the water receiving tray, causing noise and other problems.

[0049] It should be noted that the number and position of the spray nozzles of the air conditioner can be adjusted according to actual conditions, as long as the condensed water can be atomized and discharged into the outdoor air through the spray nozzle, and no specific limitation is made here. For example, in one embodiment, the air conditioner can be provided with only one spray nozzle, such as the outdoor spray nozzle 210; in this case, the water outlet of the first water pump 120 can be directly connected to the outdoor spray nozzle 210 through the water outlet pipe 140, and after extracting the condensed water from the indoor water receiving tray 110, the first water pump 120 can transport the extracted condensed water to the outside of the outdoor unit and atomize it through the outdoor spray nozzle 210 and discharge it into the outdoor air, so that the condensed water collected by the indoor water receiving tray 110 can be reasonably and properly consumed.

[0050] It should be noted that the first water pump 120 and the second water pump 230 refer to machines for conveying liquid or pressurizing liquid. It can transfer the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used for conveying liquid. According to different working principles, it can be divided into positive displacement water pumps, vane pumps and other types. Among them, the positive displacement pump uses the change of the volume of its working chamber to transfer energy; the vane pump uses the interaction between the rotating blades and water to transfer energy, and can include centrifugal pumps, axial flow pumps and mixed flow pumps. In this embodiment, the first water pump 120 and the second water pump 230 can be centrifugal pumps, diaphragm pumps, etc., and are not specifically limited here.

[0051] Reference Figure 1 In the air conditioner provided in some embodiments of the present invention, a first liquid level sensor 170 is disposed inside the indoor water receiving tray 110 , and a second liquid level sensor 250 is disposed inside the outdoor water receiving tray 220 .

[0052] It can be understood that a first liquid level sensor 170 is set inside the indoor water receiving pan 110, and a second liquid level sensor 250 is set inside the outdoor water receiving pan 220. The liquid level height of the condensed water in the indoor water receiving pan 110 can be detected by the first liquid level sensor 170, and the liquid level height of the condensed water in the outdoor water receiving pan 220 can be detected by the second liquid level sensor 250, and a corresponding control signal is given to the controller according to the liquid level height, so that the controller controls the operating status of the first water pump 120 and the second water pump 230, and can reasonably and properly handle the condensed water collected in the indoor water receiving pan 110 and the outdoor water receiving pan 220 according to the liquid level conditions.

[0053] It should be noted that the liquid level sensor can be divided into contact liquid level sensor and non-contact liquid level sensor. Common non-contact sensors include capacitive liquid level sensor, float liquid level sensor, etc. Common contact sensors include float liquid level sensor, electrode liquid level sensor and electronic liquid level sensor, etc. In one embodiment, the first liquid level sensor 170 and the second liquid level sensor 250 can be float liquid level sensors, and their working principle is: the float ball has a built-in magnet, and the float ball floats with the water level. When it approaches the reed switch, the built-in magnetic field of the float ball changes the on-off state of the reed switch and outputs a switch signal.

[0054] It should be noted that the number of the first liquid level sensors 170 can be adjusted according to actual conditions. For example, in one embodiment, two first liquid level sensors 170 can be arranged at different heights inside the indoor water receiving tray 110, respectively used to detect the upper water level height and the lower water level height of the indoor water receiving tray 110, and two second liquid level sensors 250 can be arranged at different heights inside the outdoor water receiving tray 220, respectively used to detect the upper water level height and the lower water level height of the outdoor water receiving tray 220.

[0055] Reference Figure 1 In the air conditioner provided in some embodiments of the present invention, a temperature sensor 260 is disposed inside the outdoor water receiving tray 220 .

[0056] It is understandable that a temperature sensor is provided inside the outdoor water receiving tray 220. In the heating mode, the temperature of the condensed water collected in the outdoor water receiving tray 220 can be detected by the temperature sensor 260, and a corresponding control signal can be given to the controller according to the temperature of the condensed water, so that the controller controls the operating state of the second water pump 230, thereby avoiding controlling the operation of the second water pump 230 when the condensed water in the outdoor water receiving tray 220 is frozen, thereby causing damage to the second water pump 230.

[0057] Reference Figure 1In the air conditioner provided in some embodiments of the present invention, the controller is also used to control the working state of the first water pump 120 and the second water pump 230 according to the liquid level height of the indoor water receiving tray 110 and the liquid level height of the outdoor water receiving tray 220.

[0058] In this embodiment, the controller can detect the liquid level of the condensed water in the indoor water receiving tray 110 through the first liquid level sensor 170, and detect the liquid level of the condensed water in the outdoor water receiving tray 220 through the second liquid level sensor 250, thereby controlling the operating status of the first water pump 120 and the second water pump 230, that is, the controller can reasonably and properly handle the condensed water collected in the indoor water receiving tray 110 and the outdoor water receiving tray 220 according to the liquid level conditions.

[0059] Reference Figure 1 In the air conditioner provided in some embodiments of the present invention, when the first water pump 120 is in operation and there is no water in the first water inlet pipe 150, the three-way valve 130 is controlled to connect the second inlet b with the first outlet c.

[0060] In this embodiment, the first water pump 120 is in the working state, which means that before this, the air conditioner is pumping condensed water in the indoor water receiving pan 110 to the outdoor spray port for atomization; when the water in the indoor water receiving pan 110 is pumped to a point lower than the pipe mouth of the first water inlet pipe 150, the first water inlet pipe 150 can no longer absorb the water in the indoor water receiving pan 110, or the water in the indoor water receiving pan 110 has been completely pumped out; at this time, in order to drain the residual water in the first water inlet pipe 150 and the water outlet pipe 140, the water in the water pipe will not be filled with water when winter comes. When water freezes and damages the water pipes and nozzles, the first water pump 120 will continue to be controlled to work for a period of time; at this time, the pipe mouth of the first water inlet pipe 150 is equivalent to pumping air, which will generate greater noise in the indoor unit. At this time, the three-way valve 130 is controlled to connect the second inlet b with the first outlet c, so that the water inlet of the first water pump 120 is connected to the outdoors through the air inlet pipe 160, thereby transferring the location of pumping air to the outdoors, and the location where the noise is generated to the outdoors, thereby reducing the noise of the first water pump 120 when pumping water and improving the user experience.

[0061] Next, combine Figure 1 A comprehensive and detailed introduction is given to the structure of the air conditioner provided in the embodiment of the present application.

[0062] The air conditioner includes an indoor unit, an outdoor unit and a controller, wherein:

[0063] The indoor unit includes: an indoor water receiving tray 110, a first water pump 120, a three-way valve 130 and a first liquid level sensor 170 arranged in the indoor water receiving tray 110, the indoor water receiving tray 110 is used to collect condensed water; the water outlet of the first water pump 120 is connected to the outdoor spray outlet 210 through the water outlet pipe 140; the three-way valve 130 includes a first inlet a connected to the indoor water receiving tray 110 through the first water inlet pipe 150, a second inlet b connected to the outdoors through the air inlet pipe 160, and a first outlet c connected to the water inlet of the first water pump 120;

[0064] The outdoor unit includes: an outdoor spray port 210, an outdoor water receiving tray 220 for collecting condensed water, a second water pump 230 for pumping condensed water in the outdoor water receiving tray 220 to the indoor water receiving tray 110, a second liquid level sensor 250 arranged in the outdoor water receiving tray 220, and a temperature sensor 260 arranged in the outdoor water receiving tray 220; the second water pump 230 pumps condensed water in the outdoor water receiving tray 220 to the indoor water receiving tray 110 through a water delivery pipe 240, the second water pump 230 is arranged in the outdoor water receiving tray 220, one end of the water delivery pipe 240 is connected to the second water pump 230, and the other end of the water delivery pipe 240 extends to the indoor water receiving tray 110;

[0065] The controller is respectively connected to the first water pump 120, the three-way valve 130, the first liquid level sensor 170, the second water pump 230, the second liquid level sensor 250 and the temperature sensor 260. The controller controls the operating status of the first water pump 120 and the second water pump 230 and the conduction status of the three-way valve 130 according to the liquid level height of the indoor water receiving tray 110 detected by the first liquid level sensor 170, the liquid level height of the outdoor water receiving tray 220 detected by the second liquid level sensor 250 and the condensed water temperature in the outdoor water receiving tray 220 detected by the temperature sensor 260.

[0066] Reference Figure 2 The second aspect of the present invention provides an operation control method, which is applied to the air conditioner of the first aspect of the present invention, for example, Figure 1 The operation control method of the air conditioner shown includes but is not limited to steps S210 to S230:

[0067] Step S210: Obtain the operating mode of the air conditioner.

[0068] It is understandable that the air conditioner has multiple working modes, and the parts where condensed water is generated in different working modes are different. For example, in the cooling mode, water vapor in the indoor air will condense into water when it hits the low-temperature indoor heat exchanger; in the heating mode, water vapor in the outdoor air will condense into water or adhere to the outdoor heat exchanger to form frost when it hits the low-temperature outdoor heat exchanger, and turn into water after the air conditioner defrosts. By obtaining the working mode of the air conditioner, the working state of the first water pump 120 and the conduction state of the three-way valve 130 can be controlled according to the working mode to reasonably and properly consume the condensed water collected by the indoor water receiving tray 110.

[0069] Step S220: When the air conditioner operates in cooling mode and the liquid level of the indoor water receiving pan 110 is greater than a first preset height, the three-way valve 130 is controlled to connect the first inlet a with the first outlet c, and the first water pump 120 is controlled to operate.

[0070] Step S230: When the air conditioner stops operating in the cooling mode, the first water pump 120 is controlled to continue to work for a first preset time and then stop working, and the three-way valve 130 is controlled to connect the second inlet b with the first outlet c after a second preset time;

[0071] The first preset time is greater than the second preset time.

[0072] According to the operation control method provided by the embodiment of the present invention, when the air conditioner is operating in the cooling mode, the temperature of the indoor heat exchanger of the indoor unit is low and is in a heat absorption state. The water vapor in the air passing through the indoor heat exchanger will be adsorbed on the indoor heat exchanger and condensed into condensed water, which will be collected by the indoor water receiving pan 110. Therefore, when the air conditioner is cooling, the liquid level of the indoor water receiving pan 110 will continue to rise. When the liquid level of the indoor water receiving pan 110 is greater than the first preset height, it means that there is a lot of condensed water and it needs to be consumed. At this time, the three-way valve 130 is controlled to connect the first inlet a with the first outlet c, and the first water pump 120 is controlled to work, so that the first water pump 120 can extract the condensed water collected in the indoor water receiving pan 110 through the first water inlet pipe 150 and transport it to the outdoor spray port 210 through the water outlet pipe 140, thereby atomizing and consuming the condensed water. ; In addition, when the air conditioner stops operating in the cooling mode, the first water pump 120 is controlled to continue working for the first preset time, so that the condensed water remaining in the indoor water receiving pan 110, the first water inlet pipe 150 and the water outlet pipe 140 can be cleaned up to avoid the breeding of bacteria or freezing in winter and damage to the pipeline and the nozzle; in addition, the three-way valve 130 is controlled to connect the second inlet b with the first outlet c after the second preset time, and the first preset time is greater than the second preset time, that is, in the first half of the period during which the first water pump 120 continues to work, the condensed water remaining in the indoor water receiving pan 110 and the first water inlet pipe 150 is processed, and in the second half of the period during which the first water pump 120 continues to work, the condensed water remaining in the water outlet pipe 140 is processed and the location where the noise is generated is transferred to the outdoors, thereby reducing noise and improving the user experience.

[0073] In some implementations of the present invention, the operation control method provided further includes:

[0074] In the cooling mode, when the liquid level of the outdoor water receiving pan 220 drops below a second preset height, the first water pump 120 is controlled to stop working.

[0075] In this embodiment, since the first water pump 120 will continuously extract condensed water from the outdoor water receiving pan 220 through the first water inlet pipe 150 when working in the cooling mode, the liquid level of the outdoor water receiving pan 220 will continue to decrease. When it drops below the second preset height, it means that there is less condensed water in the outdoor water receiving pan 220 in the current state and there is a larger collection space. At this time, the first water pump 120 is controlled to stop working to avoid the first water pump 120 from pumping air and generating noise. The outdoor water receiving pan 220 can continue to collect the condensed water generated in the cooling mode of the indoor mechanism until the liquid level of the indoor water receiving pan 110 is greater than the first preset height. Then the first water pump 120 is controlled to work again to extract the condensed water in the indoor water receiving pan 110 to the outdoor spray port 210 for consumption.

[0076] In some implementations of the present invention, the operation control method provided further includes:

[0077] When the air conditioner operates in heating mode, and the liquid level of the outdoor water receiving pan 220 is greater than the third preset height and the water temperature of the outdoor water receiving pan 220 is greater than the preset temperature, the second water pump 230 is controlled to operate, the three-way valve 130 is controlled to connect the first inlet a with the first outlet c, and the first water pump 120 is controlled to operate.

[0078] In this embodiment, the outdoor unit in the heating mode can generate condensed water and store it in the outdoor water receiving pan 220. The liquid level height of the outdoor water receiving pan 220 is greater than the third preset height, indicating that the condensed water is large and needs to be treated. In addition, the water temperature of the outdoor water receiving pan 220 is used as a control condition to avoid dry pumping caused by turning on the second water pump 230 when the condensed water is frozen, thereby causing damage to the water pipe and the water pump or causing the second water pump 230 to run too loudly. The preset temperature can be set to 4°C, for example. When the condensed water in the outdoor water receiving pan 220 is large and not frozen, the second water pump 230 is controlled to work so that the condensed water in the outdoor water receiving pan 220 can be pumped to the indoor water receiving pan 110. In addition, the three-way valve 130 is controlled to connect the first inlet a with the first outlet c, and the first water pump 120 is controlled to work so that the first water pump 120 can extract the condensed water collected in the indoor water receiving pan 110 through the first water inlet pipe 150 and transport it to the outdoor spray port 210 through the outlet pipe 140, thereby atomizing and consuming the condensed water.

[0079] In some implementations of the present invention, the operation control method provided further includes:

[0080] In the heating mode, when the liquid level of the indoor water receiving pan 110 is greater than the first preset height, or when the liquid level of the outdoor water receiving pan 220 drops below the fourth preset height, the second water pump 230 is controlled to stop working.

[0081] It can be understood that in the heating mode, when the second water pump 230 is working, it continuously pumps the condensed water collected in the outdoor water receiving pan 220 to the indoor water receiving pan 110. If the condensed water consumed by the first water pump 120 is less than the condensed water delivered by the second water pump 230, the condensed water in the indoor water receiving pan 110 will continue to increase. When the liquid level of the indoor water receiving pan 110 is greater than the first preset height, it means that there is too much condensed water in the indoor water receiving pan 110 and there is a risk of overflow. At this time, it is necessary to control the second water pump 230 to stop working and no longer deliver condensed water to the indoor water receiving pan 110. In addition, when the liquid level of the outdoor water receiving pan 220 drops to below the fourth preset height, it means that there is less condensed water or no condensed water in the outdoor water receiving pan 220. The second water pump 230 is controlled to stop working to avoid the second water pump 230 doing useless work and wasting energy.

[0082] In some implementations of the present invention, the operation control method provided further includes:

[0083] In the heating mode, when the liquid level of the indoor water receiving pan 110 drops below the second preset height, the three-way valve 130 is controlled to switch to connect the second inlet b with the first outlet c, and the first water pump 120 is controlled to continue working for a third preset time and then stop working.

[0084] In this embodiment, in the heating mode, when the liquid level of the indoor water receiving pan 110 drops to below the second preset height, the first water pump 120 is controlled to continue working for the third preset time, so that the residual condensed water in the first water inlet pipe 150 and the water outlet pipe 140 can be drained; in addition, the three-way valve 130 is controlled to switch to connect the second inlet b with the first outlet c, so that the water inlet of the first water pump 120 is connected to the outdoors through the air intake pipe 160, thereby transferring the air extraction location to the outdoors, and transferring the noise generation location to the outdoors, thereby reducing the noise of the first water pump 120 when pumping water, and improving the user experience.

[0109] The operation control method of the air conditioner provided in the embodiment of the present invention uses the three-way valve 130 to switch the position where the air extraction noise is generated to the pipe opening of the air inlet pipe 160 located outdoors when the first water pump 120 extracts the residual moisture in the air exhaust pipe through the first water inlet pipe 150, thereby reducing the noise of the first water pump 120 when working; the condensed water generated by outdoor defrosting is pumped to the indoor water receiving pan 110 by the second water pump 230, and then the condensed water is pumped to the outdoor spray port 210 by the first water pump 120 for atomization and spraying into the outdoor air; the condensed water collected in the indoor water receiving pan 110 is pressurized by the first water pump 120 and pumped to the indoor The external spray port 210 sprays the spray into the outdoor air; the condensed water in the indoor water receiving tray 110 is drained to avoid the breeding of bacteria; the water in the first water inlet pipe 150 and the water outlet pipe 140 is drained to avoid the water pipes and heads being damaged by freezing in winter; the liquid level detected by the first liquid level sensor 170 and the second liquid level sensor 250 is used to control the operation of the first water pump 120 and the second water pump 230; the temperature sensor 260 is used to detect the temperature of the condensed water collected in the outdoor water receiving tray 220 to reduce the dry pumping of the second water pump 230, which not only prolongs the life of the water pump, but also reduces the discomfort caused to users by the water pump noise.

[0110] Reference Figure 4 The third aspect of the present invention provides an operation control device 400, including a memory 410, a processor 420, and a computer program stored in the memory 410 and executable on the processor. The processor 420 executes the program to implement the operation control method of the second aspect of the present invention, for example, to execute Figure 2 Steps S210 to S230 of the method or execution Figure 3 The method flow in .

[0111] According to the operation control device 400 provided in the embodiment of the present invention, when the air conditioner is operated in the cooling mode, the temperature of the indoor heat exchanger of the indoor unit is low and is in a heat absorption state, and the water vapor in the air passing through the indoor heat exchanger will be adsorbed on the indoor heat exchanger and condensed into condensed water, which will be collected by the indoor water receiving pan 110. Therefore, when the air conditioner is cooling, the liquid level of the indoor water receiving pan 110 will continue to rise. When the liquid level of the indoor water receiving pan 110 is greater than the first preset height, it means that there is a lot of condensed water and it needs to be consumed. At this time, the three-way valve 130 is controlled to connect the first inlet a with the first outlet c, and the first water pump 120 is controlled to work, so that the first water pump 120 can extract the condensed water collected in the indoor water receiving pan 110 through the first water inlet pipe 150 and transport it to the outdoor spray port 210 through the water outlet pipe 140, thereby atomizing and consuming the cold water. Condensed water; in addition, when the air conditioner stops operating in the cooling mode, the first water pump 120 is controlled to continue working for the first preset time, so that the condensed water remaining in the indoor water receiving tray 110, the first water inlet pipe 150 and the water outlet pipe 140 can be cleaned up to avoid the breeding of bacteria or freezing in winter and damaging the pipeline and the nozzle; in addition, the three-way valve 130 is controlled to connect the second inlet b with the first outlet c after the second preset time, and the first preset time is greater than the second preset time, that is, in the first half of the period during which the first water pump 120 continues to work, the condensed water remaining in the indoor water receiving tray 110 and the first water inlet pipe 150 is processed, and in the second half of the period during which the first water pump 120 continues to work, the condensed water remaining in the water outlet pipe 140 is processed and the location where the noise is generated is transferred to the outdoors, thereby reducing noise and improving the user experience.

[0112] In addition, a fourth aspect of the present invention provides a computer-readable storage medium, the computer-readable storage medium stores computer-executable instructions, and the computer-executable instructions are used to enable a computer to execute the operation control method of the second aspect of the present invention, such as executing Figure 2 Steps S210 to S230 of the method or execution Figure 3 The method flow in .

Therefore, when the air conditioner is cooling, the liquid level of the indoor water receiving pan 110 will continue to rise. When the liquid level of the indoor water receiving pan 110 is greater than the first preset height, it means that there is a lot of condensed water and it needs to be consumed. At this time, the three-way valve 130 is controlled to connect the first inlet a with the first outlet c, and the first water pump 120 is controlled to work, so that the first water pump 120 can extract the condensed water collected in the indoor water receiving pan 110 through the first water inlet pipe 150 and transport it to the outdoor spray port 210 through the water outlet pipe 140, thereby atomizing and consuming the cold water. Condensed water; in addition, when the air conditioner stops operating in the cooling mode, the first water pump 120 is controlled to continue working for the first preset time, so that the condensed water remaining in the indoor water receiving tray 110, the first water inlet pipe 150 and the water outlet pipe 140 can be cleaned up to avoid the breeding of bacteria or freezing in winter and damaging the pipeline and the nozzle; in addition, the three-way valve 130 is controlled to connect the second inlet b with the first outlet c after the second preset time, and the first preset time is greater than the second preset time, that is, in the first half of the period during which the first water pump 120 continues to work, the condensed water remaining in the indoor water receiving tray 110 and the first water inlet pipe 150 is processed, and in the second half of the period during which the first water pump 120 continues to work, the condensed water remaining in the water outlet pipe 140 is processed and the location where the noise is generated is transferred to the outdoors, thereby reducing noise and improving the user experience.
