Description

Technical Field

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

[0002] Traditional window air conditioner condensate reuse methods include pumping water and spraying heat exchangers. By collecting and consuming condensate, the purpose of eliminating the need for drainage is achieved. For cooling-only air conditioners, only the condensate on the evaporator side needs to be collected for reuse; for heating-cooling air conditioners, the condensate in cooling mode is on the indoor side, and the condensate in heating mode is on the outdoor side. The condensate consumption needs to be concentrated on the indoor side or the outdoor side, and then reused. By reusing condensate, the efficiency of the heat exchanger can be improved and the problem of condensate discharge can be solved.

[0003] When the air conditioner is running in heating mode in a cold environment, when the condensed water is consumed by the outdoor fan blades, it is easy to cause problems such as insufficient consumption, splashing water, and easy freezing or damage of the fan blades. In the related art, heating spray is used to consume condensed water, but the humidity of the indoor environment will increase. At the same time, spray humidification consumes less water, takes a long time to consume, and is prone to water tank overflow. In the related art, water consumption can be achieved by high-pressure atomization without connecting a drain pipe, but high-pressure atomization requires water flow pipes and temporary water tanks. When there is residual water in the water pipe or sink and it cannot be drained for a long time, there will be problems such as freezing, clogging, odor, bacteria, and noise.

[0035] 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.

[0036] The following describes a method for controlling an air conditioner, a control device for an air conditioner, a computer-readable storage medium, and an air conditioner according to embodiments of the present invention with reference to the accompanying drawings.

[0037] Figure 1 is a flow chart of a method for controlling an air conditioner according to some embodiments of the present invention.

[0038] In some embodiments of the present invention, Figure 2 As shown, the air conditioner 100 may include: a second water tank 11 and a spray pump 12 arranged in the indoor unit 110, and a first water tank 13 and a first water pump 14 arranged in the outdoor unit 120, the spray pump 12 is configured to spray and discharge the condensed water in the second water tank of the indoor unit, and the first water pump 14 is configured to pump the condensed water in the first water tank 11 into the second water tank 13.

[0039] Continue to refer Figure 2 The air conditioner 100 of the embodiment of the present invention further includes: a second water pump 15 arranged on the indoor unit 110 and a humidifying water tank 17 arranged on the indoor heat exchanger 16, the second water pump 15 is configured to pump the condensed water in the second water storage tank 11 into the humidifying water tank 17, and the humidifying water tank 17 is configured to spray the condensed water onto the indoor heat exchanger 16.

[0040] The air conditioner 100 of the embodiment of the present invention may further include: a first water level detection switch 18 disposed in the second water storage tank 11, a spray head 19 disposed on the outdoor unit 120 and a second water level detection switch ( Figure 2 not specifically shown).

[0041] When the air conditioner is running in cooling mode, the condensed water in the second water storage tank 11 will gradually increase. When the water level detection switch 18 is triggered, the second water pump 15 and the spray pump 12 are controlled to start working, wherein the second water pump 15 is used to pump the condensed water in the second water storage tank 11 into the humidifying water tank 17, so as to spray the condensed water to the indoor heat exchanger 16 through the humidifying water tank 17, which can reduce the temperature of the indoor heat exchanger on the one hand, and consume the condensed water in the second water storage tank on the other hand. The spray pump 12 discharges the condensed water in the second water storage tank 11 through the spray head 19 to consume the condensed water in the second water storage tank.

[0042] When the air conditioner is running in heating mode, the condensed water in the first water tank 13 gradually increases. When the second water level detection switch is triggered, the first water pump 14 is controlled to start, and the condensed water in the first water tank 13 is pumped into the second water tank 11. The spray pump 12 is controlled to start, and the condensed water in the second water tank 11 is sprayed into atomized water with high pressure and discharged through the spray head 19.

[0043] In some embodiments of the present invention, a portion of the pipeline of the indoor heat exchanger 16 extends to the outdoors and is coiled in the first water tank 13, and is used to heat the space of the first water tank 13. When the air conditioner is heating at low temperature, in order to prevent the pipes of the spray pump 12 and the first water pump 14 from freezing, the spray flow path (the pipe from the spray pump to the spray head is called the spray flow path) and the water pipe flow path of the first water pump 14 are closely attached to the extended section of the indoor heat exchanger 16 to achieve heating and heat preservation in the heating mode. However, in the case of ultra-low temperature, defrosting, shutdown, etc., the space of the first water tank 13, the spray flow path, and the flow path of the first water pump 14 may be frozen, resulting in the inability to consume water normally.

[0044] like Figure 3 As shown, the second water pump 14 may include a water inlet 144, a cavity 141, a water outlet 143 and an impeller 142 provided at the water outlet 143. In a low temperature environment, residual water may accumulate at the water outlet 143, which may cause the impeller 142 to freeze and stop rotating, ice debris may occur in the cavity 141, causing the impeller 142 to be unable to rotate or rub against the ice debris, causing noise, and freezing of the water outlet 143 and the water outlet pipeline. The frozen first water pump cannot drain water or is difficult to drain water, and thawing the frozen first water pump requires special heating antifreeze measures and heating time, which increases the complexity of the system and reduces the user experience. If the temperature of the refrigerant pipe is low, the water outlet 143 that is in contact with the refrigerant pipe also has the risk of instantaneous freezing and causing the pipe to freeze. At this time, the frozen pipe cannot drain water, and heating and thawing also require a certain amount of time. Among them, Figure 3 What is shown is only a schematic diagram of the internal structure of the water pump, and it can also be a pump body with other structures that can achieve drainage.

[0045] like Figure 4As shown, since part of the spray pipeline is on the outdoor side, in a low temperature environment, when there is residual water accumulation, the spray pipeline will cause ice to clog, or ice expansion will cause the pipeline to rupture, so the spray pipeline can be fitted with the refrigerant pipe to achieve the purpose of heating and heat preservation. If the residual water in the spray pipeline cannot be completely emptied, the spray pipeline will freeze during shutdown and defrosting. Among them, the aperture of the spray hole 191 of the spray head 19 is small, and a small amount of residual water will freeze and clog the nozzle. In addition, the spray head 19 is set on the outside of the air conditioner, and direct heating and heat preservation cannot be achieved. It may also freeze during operation due to insufficient heat supply, and the thawing time after freezing is long. Therefore, it is necessary to eliminate the residual water to better prevent freezing.

[0046] To this end, an embodiment of the present invention proposes a control method for an air conditioner, which can control the rotation direction of the first water pump and / or the spray pump in combination with different operating modes of the air conditioner to eliminate water accumulation in the spray pipeline and eliminate water accumulation in the water pipe between the first water pump and the second water tank, thereby achieving the purpose of preventing freezing.

[0047] like Figure 1 As shown, the control method of the air conditioner according to the embodiment of the present invention may include the following steps:

[0048] S1, obtaining the operating mode of the air conditioner.

[0049] S2, controlling the rotation direction of the first water pump and / or the spray pump according to the operation mode of the air conditioner.

[0050] Specifically, during the operation of the air conditioner, the operation mode of the air conditioner is first obtained, and the operation mode of the air conditioner may include a heating mode and a defrosting mode. When the air conditioner is operated in the heating mode, the condensed water in the first water tank gradually increases. When the water level detection switch in the first water tank is triggered, the first water pump is started to pump the condensed water from the first water tank to the second water tank, and the spray pump rotates forward to spray the condensed water into atomized water at high pressure and discharge it through the spray head. In order to prevent water accumulation in the spray pipeline, the spray pump can be controlled to reverse and suck outdoor air, so as to absorb pure air, take away the residual water in the pipeline, dry the spray pipeline, and prevent the spray pipeline from freezing. Regardless of whether the air conditioner is operating in the cooling mode or the heating mode, by controlling the spray pump to reverse, not only can the spray pipeline be dried, but also the spray pipeline can be dredged, so as to avoid debris and dust staying in the spray pipeline for a long time, and debris and dust continue to accumulate in the nozzle, resulting in dirty and blocked spray pipelines. For another example, when the air conditioner is in defrost mode, the first water pump can be controlled to reverse, driving the rotation of the rotor to disturb and avoid freezing and jamming, maintaining the normal operation of the pipeline, and when reversing, no defrosting water passes through the pump body and pipeline, which can avoid the noise problem caused by water freezing in the cavity. Therefore, by combining the operating mode of the air conditioner, the rotation direction of the first water pump and the spray pump can be controlled to avoid water freezing in the spray pipeline and water pipe.

[0051] The control method of the air conditioner according to the embodiment of the present invention is described in detail below.

[0052] According to some embodiments of the present invention, the rotation direction of the first water pump is controlled according to the operation mode of the air conditioner, including: when the operation mode of the air conditioner is the defrost mode, the first water pump is controlled to rotate in reverse, and when the air conditioner exits the defrost mode, the first water pump is controlled to rotate forward for a first preset time. The first preset time can be calibrated according to actual conditions.

[0053] Furthermore, in some embodiments of the present invention, after controlling the first water pump to rotate forward for a first preset time, the method further includes: when the air conditioner is operated in a heating mode for a second preset time, controlling the first water pump to rotate forward for a third preset time. The second preset time and the third preset time can be calibrated according to actual conditions.

[0054] Specifically, Figure 2 Taking the air conditioner shown as an example, a part of the refrigerant pipeline of the indoor heat exchanger extends to the outdoor water tank. In the heating mode, the indoor heat exchanger is a high-temperature device. The extended refrigerant pipeline can be used to heat and insulate the water tank space. At the same time, the first water pump and the spray pump are attached to the extended refrigerant pipeline, and the high temperature of the refrigerant pipeline can be used to prevent freezing.

[0055] After the air conditioner enters defrost mode, the indoor heat exchanger becomes a low-temperature element due to the switching of the reversing valve of the air conditioner, and the lower the outdoor environment, the lower the temperature of the indoor extended refrigerant pipeline circling the first water tank, and the temperature of the refrigerant pipeline is always lower than the outdoor ambient temperature. At this time, the defrost water enters the first water tank for temporary storage. During the period when the defrost water is stored in the first water tank, the defrost water in the first water tank may freeze due to the low temperature of the outdoor environment and the low temperature of the refrigerant pipeline circling the first water tank, which will cause the impeller and the cavity to freeze. Eventually, the impeller cannot rotate or the cavity expands and pushes the plastic parts of the pump body. After the pump body freezes, when the defrost mode of the air conditioner ends and switches to the heating mode, defrosting requires a higher temperature and a longer time, resulting in poor performance and user experience of the air conditioner. If the water pump is continuously turned on during defrosting, the impeller disturbance can prevent the pump body from freezing. However, in a low temperature environment (such as below -20°C), the disturbance range caused by this continuous rotation method is small. At this time, part of the cavity will freeze, but the rotor will not freeze due to the rotation disturbance and will be stuck, resulting in the phenomenon that the rotor rubs against ice debris and makes noise. In addition, during defrosting, the temperature of the refrigerant pipeline is lower than the outdoor ambient temperature. Before the water discharged by the first water pump reaches the indoor side, the low temperature of the refrigerant pipeline causes instant freezing and blocking the pipeline, or the ice expansion causes the pipeline to rupture.

[0056] Therefore, when the operating mode of the air conditioner is the defrost mode, the first water pump is controlled to continuously reverse. The continuous reversal of the first water pump can make the rotor rotate, and the disturbance brought about can avoid freezing and jamming, thus solving the problem that higher temperature and longer time are required for thawing after freezing. In addition, when the first water pump is controlled to continuously reverse, the rotor is driven to rotate, so no defrost water passes through the pump body and pipelines, thus avoiding the noise problem caused by water accumulation and ice residue in the cavity. At the same time, since no defrost water passes through the pipeline, there is no problem of water freezing and blocking the pipeline, thus maintaining the pipeline unobstructed. When the air conditioner exits the defrost mode, the first water pump is controlled to rotate forward for the first preset time (A minutes), and the drainage is turned on, that is, the defrost water in the first water tank is pumped into the second water tank. After the water level detection switch in the second water tank is triggered, the spray pump is turned on to consume the defrost water in the second water tank. Part of the defrost water may freeze into "frozen defrost water" (a thin layer of ice) during the defrosting period. When the air conditioner runs in heating mode for the second preset time (B minutes), the water pump rotates forward for the third preset time (C minutes), and the "frozen defrost water" can be thawed by continuously heating the spiral refrigerant pipeline. If there is no drainage process for the defrosted defrost water, it will become residual water and accumulate in the second water storage tank. Therefore, after the air conditioner runs in heating mode for a period of time, the first water pump is turned on again to complete the drainage and reduce the residual defrost water.

[0057] As a specific example, Figure 5 As shown, the control method of the air conditioner of the present invention may include the following steps:

[0058] S101, the air conditioner operates in a heating mode.

[0059] S102, determine whether the water level detection switch in the first water storage tank is triggered. If yes, execute step S103; if not, execute step S104.

[0060] S103, controlling the first water pump to rotate forward for A minutes.

[0061] S104, determining whether the air conditioner has entered the defrost mode. If yes, executing step S105; if no, executing step S108.

[0062] S105, controlling the first water pump to continuously reverse until the air conditioner exits the defrost mode.

[0063] S106, control the first water pump to rotate forward for B minutes.

[0064] S107, after the air conditioner runs in the heating mode for E minutes, control the first water pump to rotate forward for C minutes.

[0065] S108, determining whether the air conditioner has received a shutdown instruction. If yes, executing step S109; if no, returning to step S101.

[0066] S109, the air conditioner is turned off.

[0067] It should be noted that the specific numerical values ​​mentioned above are only used as examples to illustrate the implementation of the present invention in detail, and should not be understood as limiting the present invention. In other examples or implementations or embodiments, other numerical values ​​can be selected according to the present invention, and are not specifically limited here.

[0068] In some embodiments of the present invention, the rotation direction of the first water pump and the spray pump is controlled according to the operation mode of the air conditioner, including: when the operation mode of the air conditioner is the heating mode, if the water level in the first water storage tank is greater than the first preset water level, the first water pump is controlled to rotate forward for a fourth preset time, and the spray pump is controlled to rotate forward for a fifth preset time. The first preset water level, the fourth preset time, and the fifth preset time can be calibrated according to actual conditions.

[0069] In some embodiments of the present invention, the spray pump is controlled to rotate forward for a fifth preset time and then reversed for a sixth preset time, wherein the sixth preset time can be calibrated according to actual conditions.

[0070] Specifically, Figure 2Taking the air conditioner shown in the figure as an example, the spray pipeline part draws water from the indoor side and sprays on the outdoor side. Therefore, part of the spray pipeline is located on the outdoor side, and the spray pipeline also needs to be close to the refrigerant pipe for heating and insulation. In the spray head part, the spray aperture is small, and a small amount of residual water can freeze and block the nozzle. In addition, the nozzle needs to be outside the air conditioner, and direct heating and insulation cannot be achieved. The operation process may also cause freezing due to insufficient heating. The thawing time after freezing is long, so eliminating residual water can better prevent freezing. When the air conditioner is running in defrost mode, due to the switching of the reversing valve, the indoor heat exchanger becomes a low-temperature element. At this time, if there is residual water accumulated in the spray pipeline, it will freeze. During the defrost period of the air conditioner, if the continuous flow disturbance is achieved by continuously opening the spray to prevent freezing, when the water volume at the spray water inlet gradually decreases to the water absorption stage, the spray pipeline continues to spray water gas, and it is impossible to extract pure air to take away the liquid. Therefore, this method can only reduce the antifreeze of the spray pump during defrost. Since it is impossible to pump pure air, a small amount of residual water will still accumulate in the spray head during the spraying process, forming small droplets. When the heat supply is insufficient, the small droplets freeze and form a blockage. In addition, during the pumping period, the spray pump will produce obvious noise when the water level gradually decreases to the mixed state of water and gas, affecting the user experience. For the spray pipeline, if the filtered fine dust stays in the pipeline or nozzle for a long time, it will become dirty and clogged. The pipeline can be unblocked by repeated airflow to reduce the risk of dirt and blockage.

[0071] When the operation mode of the air conditioner is the heating mode, if the water level in the first water tank is greater than the first preset water level (the water level detection switch in the first water tank is triggered), the first water pump is controlled to rotate forward for the fourth preset time to pump the condensed water in the first water tank into the second water tank. In the process of pumping the condensed water in the first water tank into the second water tank, in order to prevent the condensed water in the second water tank from increasing and causing overflow, the spray pump is controlled to rotate forward for the fifth preset time to ensure that part of the water in the second water tank is sprayed and drained to complete the pumping function. At the same time, it is necessary to ensure that there is still a certain water level in the second water tank and that the pumping and gas mixing stage has not been entered. While controlling the spray pump to rotate forward, the second water pump is also controlled to rotate forward to pump the condensed water in the second water tank into the humidification tank to consume the condensed water in the second water tank. At the same time, the condensed water in the humidification tank can be used to spray and cool the indoor heat exchanger. After that, the spray pump is controlled to continuously reverse for the sixth preset time. The spray pump is controlled to continuously reverse so as to suck back the residual water in the spray pipeline and continuously reverse to suck back the outdoor air, so as to absorb pure air, take away the residual water in the pipeline and dry the spray pipeline. The spray pump is controlled to rotate forward and reverse to cooperate to realize the process of drainage and drying, and at the same time avoid the stage of absorbing water and air mixing, so as to reduce the running noise. The spray pump is controlled to continuously reverse so as to dredge the spray pipeline, and avoid the debris and dust from staying in the spray pipeline for a long time, and the debris and dust from continuously accumulating in the nozzle, which leads to the dirty blockage of the spray pipeline.

[0072] When a shutdown command is received, the residual water in the spray pipe and nozzle will also freeze due to the low outdoor ambient temperature. Therefore, it is necessary to control the spray pump to rotate forward for a period of time to discharge the condensed water in the spray pipe and reduce the residual water in the pipe to prevent freezing.

[0073] In some embodiments of the present invention, the air conditioner includes: a second water pump provided in the indoor unit and a humidifying water tank provided on the indoor heat exchanger, the second water pump is configured to pump the condensed water in the second water storage tank into the humidifying water tank, the humidifying water tank is configured to spray the condensed water to the indoor heat exchanger, and the rotation direction of the spray pump is controlled according to the operation mode of the air conditioner, including: when the operation mode of the air conditioner is the cooling mode, if the water level information of the second water tank is greater than the second preset water level, the spray pump is controlled to rotate forward for the seventh preset time and then reverse for the eighth preset time; when the spray pump is controlled to rotate forward, the second water pump is controlled to rotate forward. The second preset water level, the seventh preset time and the eighth preset time can be calibrated according to actual conditions.

[0074] Furthermore, in some embodiments of the present invention, the control method of the air conditioner further comprises: upon receiving a shutdown command, controlling the spray pump to rotate forward for a ninth preset time, wherein the eighth preset time can be calibrated according to actual conditions.

[0075] Specifically, when the operation mode of the air conditioner is the cooling mode, the water level information in the second water tank is detected. If the water level information of the second water tank is greater than the second preset water level (the water level detection switch in the second water tank), the spray pump is controlled to rotate forward for the seventh preset time to discharge the condensed water in the second water tank by high-pressure spraying. After the seventh preset time, the spray pump is controlled to rotate reversely for the eighth preset time to achieve the process of drainage and drying by the coordination of forward and reverse rotation while avoiding the stage of absorbing water and gas mixing, thereby reducing the operating noise and avoiding debris and dust from staying in the spray pipeline for a long time, and debris and dust from continuously accumulating in the nozzle, resulting in dirty blockage of the spray pipeline. When the spray pump is controlled to rotate forward, the second water pump is controlled to rotate forward to pump the condensed water in the second water tank into the humidification tank to consume the condensed water in the second water tank, and at the same time, the indoor heat exchanger is sprayed and cooled through the humidification tank.

[0076] Regardless of whether the air conditioner is operating in heating mode or cooling mode, when a shutdown command is received, the spray pump is controlled to rotate forward for the ninth preset time to drain the condensed water in the second water tank to prevent the condensed water accumulated in the second water tank from having odor.

[0077] As a specific example, Figure 6 As shown, the control method of the air conditioner of the present invention may include the following steps:

[0078] S201, the air conditioner is turned on and operated.

[0079] S202, control the spray pump to rotate forward for D minutes.

[0080] S203, control the spray pump to reverse for E minutes.

[0081] S204, determine whether the water level detection switch in the second water storage tank is triggered. If yes, execute step S205; if not, execute step S208.

[0082] S205, control the spray pump to rotate forward for F minutes.

[0083] S206, control the spray pump to reverse for G minutes.

[0084] S207, controlling the second water pump to rotate forward.

[0085] S208, determining whether the air conditioner receives a shutdown signal. If yes, executing step S209; if no, returning to step S204.

[0086] S209, control the spray pump to rotate forward for H minutes and then exit.

[0087] It should be noted that the specific numerical values ​​mentioned above are only used as examples to illustrate the implementation of the present invention in detail, and should not be understood as limiting the present invention. In other examples or implementations or embodiments, other numerical values ​​can be selected according to the present invention, and are not specifically limited here.

[0088] In some embodiments of the present invention, the air conditioner further includes: a plurality of water level detection components arranged in a water tank, the plurality of water level detection components being configured to detect water level information of a first water tank, and the method further includes: determining a tilt angle of the first water tank based on the water level information of the first water tank detected by the plurality of water level detection components; and issuing a reminder message when the tilt angle of the first water tank does not meet a preset condition.

[0089] Specifically, the horizontal and vertical directions of the first water tank during installation have a greater impact on drainage. When the installation of the first water tank does not meet the design requirements, or when the position of the first water tank is offset during use, the water storage capacity of the tank will change, and the drainage water level, warning water level, and drainage volume will all differ from the design values. When water accumulates in the first water tank, the accumulated water continues to remain in the first water tank and cannot be drained away. The accumulated water will cause a variety of health problems such as odor and bacteria, reduce the effective volume of the tank, and freeze at low temperatures. In a low-temperature environment, after a long period of water accumulation and freezing, the ice expands to occupy more volume, continuously reducing the water storage capacity. When the heating capacity in the tank is insufficient and the thickness of the ice continues to accumulate, there will be a risk of overflow.

[0090] In order to solve the above problems, Figure 7 As shown in (a top view of the first water storage tank and the water level detection switch arranged in the first water storage tank), multiple water level detection components are installed in the first water storage tank, and the multiple water level detection components are used to adjust the horizontal inclination angle and the vertical degree. Take the arrangement of three water level detectors, water level switch 1, water level switch 2 and water level switch 3, and the calibration at the first start-up after installation as an example to illustrate how to adjust the position of the first water storage tank. Prompt the user to add water to the first water storage tank, and then the three water level detectors are in the detection state until any water level detector begins to detect the water level to cancel the prompt. When any water level reaches the value of L, it is prompted to stop adding water. When any water level height value is greater than M, it means that too much water is added, and there is a risk of overflow during the adjustment process. Therefore, it is necessary to start the first water pump to extract some excess water. When any water level reaches H, the first water pump stops. Adjust the horizontal installation inclination, judge the water level height values ​​of water level switch 1 and water level switch 2, and it is necessary to meet the requirement that the water level value of water level switch 1 is greater than that of water level switch 2, and the height difference is within the set range. Adjust the vertical installation tilt angle to determine the water level values ​​of water level switch 2 and water level switch 3. The water level value of water level switch 2 must be greater than that of water level switch 3, and the height difference must be within the set range. By adjusting the water level detector, the installation tilt angle of the first water tank can be made to meet the design angle, so that water can flow to one end of the first water pump and avoid residual water accumulation in the first water tank. The number and position of the water level switches can be adjusted according to the shape of the first water tank.

[0091] As a specific example, Figure 8 As shown, the control method of the air conditioner of the present invention may include the following steps:

[0092] S301, the air conditioner is turned on for the first time.

[0093] S302, prompt "add water to the sink".

[0094] S303, three water level detectors are enabled.

[0095] S304, any water level detector detects a water level value.

[0096] S305, when any water level reaches the L value, a prompt stops.

[0097] S306, determine whether any water level value is greater than M. If yes, execute step S307; if not, execute step S308.

[0098] S307, controlling the first water pump to rotate forward.

[0099] S308, controlling the first water pump to stop.

[0100] S309, Determine whether the water level height of water level switch 2 < the water level height of water level switch 1 holds. If so, execute step S311; if not, execute step S310.

[0101] S310, Prompt "The right end goes up or the left end goes down".

[0102] S311, Determine whether F1 < |the water level height of water level switch 2 - the water level height of water level switch 1| < F2 holds. If so, execute step S313; if not, execute step S312.

[0103] S312, Prompt "The right end goes down or the left end goes up".

[0104] S313, Determine whether the water level height of water level switch 3 < the water level height of water level switch 2 holds. If so, execute step S315; if not, execute step S314.

[0105] S314, Prompt "The front end goes up or the back end goes down".

[0106] S315, Determine whether F1 < |the water level height of water level switch 3 - the water level height of water level switch 2| < F2 holds. If so, execute step S317; if not, execute step S316.

[0107] S316, Prompt "The front end goes down or the back end goes up".

[0108] S317, The position adjustment of the first water storage tank is completed.
