[0049] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0051] An embodiment of the present application provides a control method, device, equipment and storage medium for an air conditioner. The air conditioner includes a water receiving container for collecting condensed water and a drain pump for discharging condensed water in the water receiving container, aiming to effectively detect the blockage state of the drain pump and improve the service life of the drain pump.

[0052] Before describing the control method of the air conditioner according to the embodiment of the present application, the air conditioner is first described by way of example.

[0053] When the indoor unit of the air conditioner is cooling, its internal temperature is lower than the room temperature, and the water vapor in the air will condense on the surface of each internal structure. In order to prevent the condensed water from corroding the equipment, a water receiving container is provided, wherein the water receiving container can be a water receiving tray for condensed water, and a condensed water drainage pump is provided to discharge the condensed water in the water receiving tray. The drainage pump is fixed on the structure above the water receiving tray.

[0054] A drainage pump is a machine that transports liquid or pressurizes liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the liquid energy. It is mainly used to transport liquid. According to different working principles, it can be divided into positive displacement water pumps, vane pumps and other types. Positive displacement pumps use the change in the volume of their working chambers to transfer energy; vane pumps use the interaction between rotating blades and water to transfer energy. There are centrifugal pumps, axial flow pumps and mixed flow pumps. Centrifugal pumps and diaphragm pumps are commonly used to drain condensate in air conditioners.

[0055] The air conditioner also includes a water level switch, which is a switch used to control the water level. In terms of form, it is mainly divided into contact type and non-contact type. Commonly used non-contact switches include capacitive liquid level switch, magnet reed switch float type (the float has a built-in magnet, and the float floats with the water level. When it approaches the reed switch, the built-in magnetic field of the float changes the on-off state of the reed switch and outputs a switch signal). The contact float type liquid level switch is the most widely used. Electrode type liquid level switch, electronic liquid level switch, and capacitive liquid level switch can also be implemented by contact method. The float type water level switch is commonly used in air conditioners.

[0056] When the amount of condensed water turns on the water level switch, the drain pump starts to drain; when the water level is not enough to turn on the water level switch, the drain pump stops draining, thereby ensuring that the condensed water in the water tray does not overflow.

[0057] In the related art, the design is based on the premise that the drainage pump can continue to work normally, and the situation where the drainage pump is dirty and blocked is not taken into consideration.

[0058] The present application provides a control method for an air conditioner, wherein the air conditioner comprises a water receiving container for collecting condensed water and a drainage pump for draining the condensed water in the water receiving container. Figure 1 As shown, the method includes:

[0059] Step 101: When the air conditioner is in a cooling state, it is determined that the water level in the water receiving container is greater than or equal to a first water level, and the drainage pump is controlled to be in a running state.

[0060] For example, when the air conditioning device is in a startup state, it can be determined whether the air conditioning device is in a cooling working state.

[0061] In other embodiments, when the air-conditioning device is not in the cooling working state, it is re-determined whether the air-conditioning device is in the cooling working state.

[0062] Exemplarily, based on the first switch state of the first water level switch in the air conditioner being in the on state, it can be determined that the water level in the water receiving container is greater than or equal to the first water level, wherein the first water level may be a high water level.

[0063] In other embodiments, based on the first switch state of the first water level switch in the air conditioner being the off state, it can be determined that the water level in the water receiving container is less than the first water level, and the drainage pump is controlled to be in the off state.

[0064] Step 102: If it is determined that the first operation time of the drainage pump is greater than or equal to the preset time and the water level in the water receiving container is greater than or equal to the second water level, a first alarm message is generated; the first alarm message is used to indicate that the drainage pump is in a first state of blockage.

[0065] In other embodiments, when the drainage pump is in operation, the timing device of the air conditioner is controlled to be in operation; the operation time of the timing device is determined as the first time length D1. The timing device being in operation may be reset and start timing; the timing device may be a timer.

[0066] Exemplarily, based on the second switch state of the second water level switch in the air conditioner being in the on state, it can be determined that the water level in the water receiving container is greater than or equal to the second water level, wherein the second water level can be a low water level. The preset time length T1 can be the maximum time required for the water level in the water receiving container to drop from the first water level to the second water level. In this way, it can be determined that the drain pump is in the first state of obstruction, and a first alarm message is generated to prompt the user to repair the drain pump and extend the service life of the drain pump, when the maximum time required for the water level in the water receiving container to drop from the first water level to the second water level is exceeded and the water level in the water receiving container has not dropped to the second water level.

[0067] In other embodiments, if it is determined that the first time duration is less than the preset time duration and the second water level is greater than or equal to the second water level, the drain pump is controlled to be in operation; until it is determined that the first time duration of the drain pump operation is greater than or equal to the preset time duration and the water level in the water receiving container is greater than or equal to the second water level, a first alarm message is generated. In this way, the drain pump can be continuously operated within the maximum time required for the water level in the water receiving container to drop from the first water level to the second water level, and if the water level in the water receiving container has not dropped to the second water level, the condensed water in the water receiving container can be effectively discharged.

[0068] In other embodiments, if it is determined that the first time duration is less than the preset time duration and the second water level is less than the second water level, the drain pump is controlled to be in an off state. In this way, the drain pump can be stopped within the maximum time required for the water level in the water receiving container to drop from the first water level to the second water level, and when the water level in the water receiving container has dropped to the second water level, the life of the drain pump can be effectively extended.

[0069] Exemplarily, the drain pump being in a first state of being blocked may include: the drain pump being in a second state of having its water inlet blocked, the drain pump being in a third state of having its water inlet blocked, and the drain pump being in a fourth state of having its water outlet blocked.

[0070] In an application example, after determining that the first operation time of the drainage pump is greater than or equal to the preset time and the water level in the water receiving container is greater than or equal to the second water level, the method further includes:

[0071] Get the working current of the drainage pump;

[0072] If it is determined that the working current is less than or equal to the first preset current, a second alarm message is generated; the second alarm message is used to indicate that the drainage pump is in a second state where the water inlet is blocked;

[0073] The drainage pump is controlled to be in a closed state based on the second alarm information.

[0074] Exemplarily, the first preset current may be the normal operating current of the drain pump. As an example, the first preset current may be any current in the range of 191 mA-196 mA. The drain pump is in the second state of blocked water inlet, which may be that the water inlet of the drain pump is partially blocked, resulting in less water entering the drain pump, thereby causing the working current of the drain pump to be less than the normal operating current of the drain pump.

[0075] In this way, when the working current is less than or equal to the normal operating current of the drainage pump, it can be determined that the water inlet of the drainage pump is partially blocked, and a second alarm message can be generated to prompt the user to repair the water inlet of the drainage pump, thereby accurately locating the blockage position and reducing the difficulty of maintenance work and maintenance cycle.

[0076] In an application example, after determining that the first operation time of the drainage pump is greater than or equal to the preset time and the water level in the water receiving container is greater than or equal to the second water level, the method further includes:

[0077] If it is determined that the working current is less than or equal to the second preset current, a third alarm message is generated; the third alarm message is used to indicate that the drainage pump is in a third state where the water inlet is blocked;

[0078] Controlling the drainage pump to be in a closed state based on the third alarm information;

[0079] The second preset current is smaller than the first preset current.

[0080] Exemplarily, the second preset current may be a dead-time current of the drain pump. As an example, the dead-time current may be 10 mA. The drain pump is in the third state of blocked water inlet, which may be that the water inlet of the drain pump is completely blocked, resulting in almost no water entering the drain pump, and the speed of the impeller in the drain pump is reduced, or even almost stopped, resulting in the working current of the drain pump being equal to the dead-time current of the drain pump.

[0081] In this way, when the working current is less than or equal to the shutdown current of the drainage pump, it can be determined that the water inlet of the drainage pump is completely blocked, and a third alarm message can be generated to prompt the user to repair the water inlet of the drainage pump, thereby accurately locating the blockage position and reducing the difficulty of maintenance work and maintenance cycle.

[0082] In an application example, after determining that the first operation time of the drainage pump is greater than or equal to the preset time and the water level in the water receiving container is greater than or equal to the second water level, the method further includes:

[0083] If it is determined that the working current is greater than the first preset current, a fourth alarm message is generated; the fourth alarm message is used to indicate that the drainage pump is in a fourth state where the water outlet is blocked;

[0084] Based on the fourth alarm information, the drainage pump is controlled to be in a closed state.

[0085] Exemplarily, the drain pump is in the fourth state of blocked water outlet, which may be that the water outlet of the drain pump is partially blocked, resulting in less water discharged from the drain pump, and further causing the working current of the drain pump to be greater than the normal operating current of the drain pump.

[0086] In this way, when the working current is greater than the normal operating current of the drainage pump, it can be determined that the water outlet of the drainage pump is partially blocked, and a fourth alarm message can be generated to prompt the user to repair the water outlet of the drainage pump, thereby accurately locating the blockage position and reducing the difficulty of maintenance work and maintenance cycle.

[0087] In an application example, the method further includes:

[0088] Determine that the water level in the water receiving container is lower than the second water level, and control the drainage pump assembly to be in a closed state.

[0089] For example, the water level in the water receiving container can be determined to be less than the second water level based on the second switch state of the second water level switch in the air conditioner being in the off state. In this way, when the water level in the water receiving container has dropped to the second water level, the drain pump is stopped, effectively prolonging the life of the drain pump.

[0090] Step 103: Based on the first alarm information, the drainage pump is controlled to be in an off state.

[0091] It can be understood that controlling the drainage pump to be in an off state based on the first alarm information may be generating a control instruction based on the first alarm information, and controlling the drainage pump to be in an off state according to the control instruction.

[0092] In an application example, the air conditioner includes a first water level switch and a second water level switch; the method further includes:

[0093] Acquire a first switch state of the first water level switch and a second switch state of the second water level switch;

[0094] When the first switch state is in the on state, determining that the water level in the water receiving container is greater than or equal to the first water level;

[0095] When the second switch state is in the on state, determining that the water level in the water receiving container is greater than or equal to the second water level;

[0096] When the second switch state is the off state, it is determined that the water level in the water receiving container is less than the second water level.

[0097] In other embodiments, when the first switch state is the off state, it is determined that the water level in the water receiving container is less than the first water level.

[0098] In an application example, the method further includes:

[0099] Determining a first ratio of the operating current to the first preset current;

[0100] When the first ratio is greater than or equal to the first preset ratio, a first prompt message is generated; the first prompt message is used to instruct to clean the water outlet of the drainage pump;

[0101] When the first ratio is less than or equal to the second preset ratio, a second prompt message is generated; the second prompt message is used to instruct to clean the water inlet of the drainage pump;

[0102] Among them, the first preset ratio is greater than the second preset ratio.

[0103] Exemplarily, the first preset ratio may be a ratio corresponding to a 50% blockage of the water outlet of the drain pump. As an example, the first preset ratio may be 1.1. The second preset ratio may be a ratio corresponding to a 50% blockage of the water inlet of the drain pump. As an example, the second preset ratio may be 0.8. In this way, when the first ratio of the working current to the first preset current is greater than or equal to the first preset ratio of 1.1, it can be determined that the water outlet of the drain pump is blocked by 50%, and a first prompt message is generated to prompt the user to clean the water outlet of the drain pump; when the first ratio of the working current to the first preset current is less than or equal to the second preset ratio of 0.8, it can be determined that the water inlet of the drain pump is blocked by 50%, and a second prompt message is generated to prompt the user to clean the water inlet of the drain pump, which can extend the user's cleaning cycle of the water pump as much as possible and improve the user experience.

[0104] In an application example, the method further includes:

[0105] When the air conditioner is in a cooling stop state, determining a second operation time of the drain pump assembly;

[0106] The drainage pump is controlled to be in an operating state based on the second time period.

[0107] For example, the second time duration T2 may be the shortest time required for the water level in the water receiving container to drop from the second water level to the empty water level. The second time duration may be greater than the preset time duration. In this way, when the air conditioner stops running, the drainage pump may be controlled to run for the second time duration to drop the water level in the water receiving container from the second water level to the empty water level, thereby effectively draining the water in the water receiving container.

[0108] In order to understand the embodiment of the present invention, a control method for a dirty drainage pump is used as an example for description. The control method is applied to a control system such as Figure 2 As shown, the control system includes a power supply component, a central processing unit, a storage component, a display component, a control component, a drainage pump, etc. The power supply component supplies power to the system to ensure the normal execution of functions; the central processing unit receives input information, packages and sends information instructions to other components, and controls the normal operation of the entire system; the storage component is used to store important information required for the operation of the system; the display component can display the error information issued when the system reports an error, as well as the various parameter information when the air conditioner is operating normally; after receiving the instruction information, the control component can control the operation of the drainage pump; the drainage pump can discharge the condensed water generated by the air conditioner refrigeration out of the equipment.

[0109] The control system works as follows: After the air conditioner starts cooling and runs normally for a period of time, when the water level in the water tray reaches the high water level (L1), the drain pump starts running, the timer is reset and starts timing. During the operation of the drain pump, the water level is monitored at any time. During the period of 0≤D1≤T1, if it is found that the water level in the water tray has reached the low water level (L2), the drain pump stops running, the timer D1 is reset again, and when the water level reaches L1 again, the timer starts timing again; when D1≥T1, the water level in the water tray is detected. If the water level reaches L2, the drain pump stops running and the timer D1 is reset; if the water level does not reach L2, the system reports an error, indicating that the drain pump is dirty and blocked.

[0110] like Figure 3 , Application Example 1 of the Control Method for Dirty Blockage of Drainage Pump:

[0112] Step 302: determine whether the air conditioner is in cooling mode. If yes, execute step 303; if no, repeat step 302.

[0120] Step 3010: the system reports an error, indicating that the drainage pump is blocked by dirt, and then executes step 3013;

[0121] Step 3011, determine whether the air conditioner is turned off for cooling, if so, execute step 3012; otherwise, execute step 303;

[0122] Step 3012, the drainage pump runs again for a period of T2;

[0123] Step 3013: the drainage pump stops running;

[0124] Step 3014: Turn off the air conditioner.
