Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioner water receiving tray and an air conditioner anti-condensation control method and device. Background Art

[0002] During the use of the air conditioner, a large amount of condensed water will be generated, and the condensed water needs to be discharged reliably. The air conditioner water receiving pan is used to collect the condensed water generated when the air conditioner heat exchanger is working. In the prior art, a water receiving pan is usually set under the heat exchanger, and the condensed water generated on the surface of the heat exchanger falls into the water receiving pan and is discharged through the drain port on the water receiving pan.

[0003] Since the condensate generation rate of the air conditioner is an important part of many air conditioning controls, the air conditioner water tray can directly reflect the condensate generation rate. In the existing air conditioner water tray, there is no corresponding relationship between the water level in the air conditioner water tray and the water inlet speed, and the water inlet speed cannot be directly determined by the water level. If you want to know the water inlet speed, you need to accurately measure the water inlet time and the real-time water level to calculate it. Although the accuracy obtained in this way is relatively high, the process is relatively complicated. Therefore, there is a need for an air conditioner water tray that can reflect the water inlet speed through the water level. Summary of the invention

[0004] The problem solved by the invention is that the existing water receiving tray of the air conditioner cannot reflect the water inflow speed through the water level.

[0005] To solve the above problems, the present invention provides an air conditioner water tray, comprising a water tray body and a drain port, wherein the drain port is arranged on the side wall of the water tray body, and the drainage cross-sectional area of ​​the drain port increases with the increase of the water accumulation depth in the water tray body.

[0006] In this way, the drainage cross-sectional area of ​​the drainage port is increased as the water depth of the water receiving pan body increases, that is, different drainage cross-sectional drainage ports are set corresponding to different water accumulation depths, and the change of the drainage port liquid level changes with the change of the water accumulation depth of the water receiving pan body, and the water receiving pan body is used to accommodate condensed water that directly drips or slides from the evaporator, so that the water accumulation depth of the water receiving pan body can reflect the generation speed of condensed water in the air conditioner evaporator to a certain extent. In addition, since different drainage cross-sectional drainage ports are set corresponding to different water accumulation depths, the condensed water can be effectively and timely discharged, preventing the generated condensed water from overflowing the water receiving pan body and causing unnecessary losses.

[0007] Optionally, the cross-sectional width of the drain outlet gradually decreases from top to bottom.

[0008] In this way, when the water level in the water receiving pan body is low, the cross-sectional width of the drain outlet is small, so that the water level can change rapidly, quickly accumulating from a low water level to a relatively high water level, so that the detection device can quickly identify the water depth position and avoid detection lag; and when the water level in the water receiving pan body is high, the cross-sectional width of the drain outlet is large, which can speed up the drainage speed and avoid water overflow.

[0009] Optionally, the cross-sectional width of the drain outlet gradually decreases from top to bottom in a stepped manner.

[0010] In this way, the cross-sectional width of the drain port gradually decreases in a step-like manner, which is conducive to providing a certain buffer space for the condensed water, avoiding a strong impact force when the condensed water is discharged, which is difficult to control. By setting the cross-sectional width of the drain port to gradually decrease in a step-like manner, the condensed water can be discharged evenly, which facilitates the discharge control operation of the condensed water.

[0011] Optionally, the air conditioner water receiving tray further comprises a water level detection device, and the water level detection device is arranged on the water receiving tray body to detect the depth of accumulated water in the water receiving tray body.

[0012] In this way, by providing the water level detection device, it is convenient to grasp the change of the water depth in the water receiving tray body in real time.

[0013] Optionally, the water receiving tray body includes a water storage portion and a detection portion, the drain port is arranged on a side wall of the water storage portion, and the water level detection device is arranged on the detection portion.

[0014] In this way, setting the drain port on the side wall of the water storage part can reduce interference with the detection of the water depth and reduce the detection error of the water depth, and it is convenient to set the drain port. Moreover, by setting the drain port on the side wall of the water storage part, the corresponding relationship between the drainage area and the water depth can be directly established, and the change of the water depth changes with the change of the side wall liquid level, which is convenient for grasping the change of the water depth of the condensed water at any time.

[0015] Optionally, the water storage portion and the detection portion are separated by a hollow partition.

[0016] In this way, the water storage part and the detection part are separated by a partition, and the partition is designed to be hollowed out to ensure that the water levels of the water storage part and the detection part are consistent. When the depth of the accumulated water is to be detected, since the water levels of the water storage part and the detection part are consistent, when detecting the depth of the accumulated water, it is only necessary to detect the detection part, which is convenient for detecting the depth of the accumulated water.

[0017] Optionally, the water level detection device includes a floating member, which is disposed in the detection portion, and a position of the floating member is consistent with a water surface of the detection portion.

[0018] In this way, a floating member is provided in the detection part, and the position of the floating member is consistent with the water surface of the detection part. The floating member is used to display the water level, so as to grasp the change of the depth of the accumulated water.

[0019] Optionally, the water level detection device further comprises a conductive structure and a water level detection circuit, wherein the conductive structure is arranged on a side where the floating member contacts the inner wall of the detection portion, and the water level detection circuit is arranged at a corresponding position on the inner wall where the detection portion contacts the floating member.

[0020] In this way, a conductive structure is provided on the side of the floating member that contacts the inner wall of the detection portion, and the water level detection circuit is turned on through the conductive structure, thereby facilitating the detection of the depth of accumulated water.

[0021] Optionally, a plurality of the water level detection circuits are arranged vertically on the inner wall of the detection portion and the water level detection circuits are turned on after contacting the conductive structure.

[0022] In this way, water level detection circuits are set up at different water level heights to facilitate the detection of water depths at different heights. When the water depths are different, only a very small number of water level detection circuits are set up, which will cause large errors in the detection data during the detection process, which is not conducive to the real-time detection of the water depth.

[0023] Optionally, the conductive structure is a metal sheet, and the length of the metal sheet is greater than the height difference between adjacent water level detection circuits.

[0024] Thus, when the metal sheet is located between adjacent water level detection circuits, the metal sheet fails to contact and conduct with any water level detection circuit, and thus the data of the water depth cannot be detected. By setting the length of the metal sheet to be greater than the height difference between the adjacent water level detection circuits, the situation where the metal sheet is located between adjacent water level detection circuits can be avoided, thereby ensuring that the water level detection circuit can be conducted at any position of the metal sheet, which is convenient for detecting the water depth.

[0025] Optionally, the conductive structure is a metal sheet, and the length of the metal sheet is smaller than the maximum height difference between three adjacent water level detection circuits.

[0026] In this way, the length of the metal sheet is smaller than the maximum height difference between three adjacent water level detection circuits, so as to reduce the detection interference caused by the simultaneous conduction of multiple water level detection circuits.

[0027] Secondly, an air conditioner anti-condensation control method is provided, wherein the air conditioner includes the air conditioner water receiving tray described above, and the anti-condensation control method includes:

[0028] In cooling mode, obtaining water level data of a water level detection device of the water receiving pan of the air conditioner;

[0029] Get the current operating parameters of the air conditioner;

[0030] The water depth of the water receiving pan of the air conditioner is determined according to the water level data, and the operating parameters are adjusted according to the water depth of the water receiving pan of the air conditioner.

[0031] In this way, water level data is obtained through the water level detection device of the air conditioner water tray, thereby obtaining the water accumulation depth of the water tray. The water tray is used to hold condensed water that drips or slides directly from the evaporator. The water accumulation depth of the water tray body reflects the speed of condensation water generation, thereby determining the difficulty of condensation generation at the air outlet of the air conditioner in the current environment, and then adjusting the operating parameters of the air conditioner for advance control, thereby effectively avoiding the formation of condensation water droplets around the air outlet of the air conditioner.

[0032] Optionally, determining the water depth of the air conditioner water tray according to the water level data, and adjusting the operating parameters according to the water depth of the air conditioner water tray includes:

[0033] Determine the water depth according to the water level data;

[0034] Determining whether the accumulated water depth exceeds a first water level threshold;

[0035] If the water accumulation depth does not exceed the first water level threshold, the air conditioner is controlled to operate according to the current operating parameters, and the step of obtaining the water level data of the water level detection device of the water tray of the air conditioner is re-executed.

[0036] In this way, when the depth of accumulated water does not exceed the first water level threshold, it means that the speed of condensation water generation is relatively slow and still within a safe range, and the operating parameters are relatively appropriate. In addition, by re-acquiring the water level data of the water level detection device of the air conditioner water tray, the depth of accumulated water is detected in real time, which facilitates timely adjustment of the operating parameters of the air conditioner.

[0037] Optionally, if the water accumulation depth exceeds the first water level threshold, the compressor frequency in the operating parameters of the air conditioner is reduced.

[0038] In this way, when the water accumulation depth is greater than the first water level threshold, the compressor frequency is reduced, and the refrigeration function is reduced to slow down the generation rate of condensation water, effectively prevent condensation generation, and improve user experience.

[0039] Optionally, the determining the water depth of the air conditioner water tray according to the water level data, and adjusting the operating parameters according to the water depth of the air conditioner water tray, further includes:

[0040] If the water depth exceeds the first water level threshold, determining whether the water depth exceeds a second water level threshold, the second water level threshold being greater than the first water level threshold;

[0041] If the water accumulation depth does not exceed the second water level threshold, the compressor frequency in the operating parameters of the air conditioner is reduced by a first frequency.

[0042] In this way, when the water accumulation depth is between the first water level threshold and the second water level threshold, the compressor frequency is reduced, and the refrigeration function is reduced to slow down the generation rate of condensation water, effectively prevent condensation generation, and improve user experience.

[0043] Optionally, the determining the water depth of the air conditioner water tray according to the water level data, and adjusting the operating parameters according to the water depth of the air conditioner water tray, further includes:

[0044] If the water accumulation depth exceeds the second water level threshold, the compressor frequency is reduced by a second frequency, and the second frequency is greater than the first frequency.

[0045] Determine whether the accumulated water depth exceeds a third water level threshold, the third water level threshold being greater than the second water level threshold;

[0046] If the water accumulation depth does not exceed the third water level threshold, the rotation speed of the internal fan in the operating parameters of the air conditioner is increased by a first rotation speed.

[0047] In this way, when the water depth exceeds the second water level threshold, the cooling capacity is reduced by reducing the compressor frequency to a second frequency with a larger amplitude, so that the generation rate of condensation water is slowed down; and when the water depth is between the second water level threshold and the third water level threshold, the water depth is relatively large and the generation rate of condensation water is relatively fast. By increasing the speed of the internal fan and reducing the refrigeration function, the generation rate of condensation water is slower.

[0048] Optionally, the determining the water depth of the air conditioner water tray according to the water level data, and adjusting the operating parameters according to the water depth of the air conditioner water tray, further includes:

[0049] If the accumulated water depth exceeds the third water level threshold, the rotation speed of the internal fan is increased to a second rotation speed; the second rotation speed is greater than the first rotation speed.

[0050] In this way, when the water depth exceeds the third water level threshold, the water depth is close to the maximum water level. By increasing the speed of the internal fan and setting the second speed greater than the first speed, the generation rate of condensation water is slowed down to prevent condensation water from overflowing.

[0051] A control device for an air conditioner is provided again, the air conditioner comprising the air conditioner water receiving tray described above, the control device for the air conditioner comprising:

[0052] An acquisition unit, which is used to acquire water level data of a water level detection device of the water receiving pan of the air conditioner in a cooling mode;

[0053] A detection unit, which is used to obtain the current operating parameters of the air conditioner;

[0054] An adjustment unit is used to determine the water depth of the air conditioner water tray according to the water level data, and adjust the operating parameters according to the water depth of the air conditioner water tray.

[0055] In this way, water level data is obtained through the water level detection device of the air conditioner water tray, thereby obtaining the water accumulation depth of the air conditioner water tray, and the water tray is used to hold condensed water that drips or slides directly from the evaporator. The water accumulation depth of the water tray body reflects the speed of condensation water generation, thereby determining the difficulty of condensation generation at the air outlet of the air conditioner in the current environment, and then adjusting the operating parameters of the air conditioner for advance control, thereby effectively avoiding the formation of condensation water droplets around the air outlet of the air conditioner.

[0056] An air conditioner is provided, comprising the air conditioner water receiving pan as described above.

[0057] In this way, the drainage cross-sectional area of ​​the drainage port is increased as the water depth of the water receiving pan body increases, that is, different drainage cross-sectional drainage ports are set corresponding to different water accumulation depths, and the change of the drainage port liquid level changes with the change of the water accumulation depth of the water receiving pan body, and the water receiving pan body is used to accommodate condensed water that directly drips or slides from the evaporator, so that the water accumulation depth of the water receiving pan body can reflect the generation speed of condensed water in the air conditioner evaporator to a certain extent. In addition, since different drainage cross-sectional drainage ports are set corresponding to different water accumulation depths, the condensed water can be effectively and timely discharged, preventing the generated condensed water from overflowing the water receiving pan body and causing unnecessary losses.

[0058] An air conditioner is provided again, comprising a computer-readable storage medium storing a computer program and a processor, wherein when the computer program is read and executed by the processor, the above-mentioned air conditioner anti-condensation control method is implemented.

[0059] In this way, water level data is obtained through the water level detection device of the air conditioner water tray, thereby obtaining the water accumulation depth of the air conditioner water tray, and the water tray is used to hold condensed water that drips or slides directly from the evaporator. The water accumulation depth of the water tray body reflects the speed of condensation water generation, thereby determining the difficulty of condensation generation at the air outlet of the air conditioner in the current environment, and then adjusting the operating parameters of the air conditioner for advance control, thereby effectively avoiding the formation of condensation water droplets around the air outlet of the air conditioner.

[0060] Finally, a computer-readable storage medium is provided, wherein the computer-readable storage medium stores a computer program, and when the computer program is read and executed by a processor, the above-mentioned air conditioner anti-condensation control method is implemented.

[0061] In this way, water level data is obtained through the water level detection device of the air conditioner water tray, thereby obtaining the water accumulation depth of the air conditioner water tray, and the water tray is used to hold condensed water that drips or slides directly from the evaporator. The water accumulation depth of the water tray body reflects the speed of condensation water generation, thereby determining the difficulty of condensation generation at the air outlet of the air conditioner in the current environment, and then adjusting the operating parameters of the air conditioner for advance control, thereby effectively avoiding the formation of condensation water droplets around the air outlet of the air conditioner.

[0077] During the use of the air conditioner, a large amount of condensed water will be generated, and the condensed water needs to be discharged reliably. The air conditioner water receiving pan is used to collect the condensed water generated when the air conditioner heat exchanger is working. In the prior art, a water receiving pan is usually set under the heat exchanger, and the condensed water generated on the surface of the heat exchanger falls into the water receiving pan and is discharged through the drain port on the water receiving pan.

[0078] Since the condensate generation rate of the air conditioner is an important part of many air conditioning controls, the air conditioner water tray can directly reflect the condensate generation rate. In the existing air conditioner water tray, there is no corresponding relationship between the water level in the air conditioner water tray and the water inlet speed, and the water inlet speed cannot be directly determined by the water level. If you want to know the water inlet speed, you need to accurately measure the water inlet time and the real-time water level to calculate it. Although the accuracy obtained in this way is relatively high, the process is relatively complicated. Therefore, there is a need for an air conditioner water tray that can reflect the water inlet speed through the water level.

[0079] In addition, as living standards improve, people's requirements for indoor environmental comfort also become higher. In order to improve the user experience, many air conditioners are designed with a windless blowing function. By setting many micro holes on the air guide plate of the air conditioner outlet, when the air guide plate is closed, the air speed of the air conditioner outlet is reduced after passing through the micro holes, realizing the windless function. However, when realizing the windless function, the air volume of the air conditioner is reduced, and the evaporation temperature and the air outlet temperature are reduced. Condensation is easily formed around the air outlet of the air conditioner and even drips onto the floor, causing property losses to users and affecting the user experience.

[0080] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0081] A coordinate system XYZ is provided in the drawings of the embodiments of the present invention, wherein X, Y, and Z represent different directions, and the directions or positional relationships indicated by the terms "upper" and "lower" etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0082] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0083] In the description of this specification, the description with reference to the terms "embodiment", "one embodiment" and "one implementation" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or implementation are included in at least one embodiment or implementation of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or implementation. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.

[0084] like Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 is a schematic diagram of a front view of a water receiving tray of an air conditioner according to an embodiment of the present invention, Figure 2 is a schematic diagram of a top view of a water receiving tray of an air conditioner according to an embodiment of the present invention, Figure 3 The present invention is a schematic diagram of a left view of an air conditioner water tray according to an embodiment of the present invention. The present invention discloses an air conditioner water tray, comprising a water tray body and a drain port 1, wherein the drain port 1 is arranged on a side wall of the water tray body, and the drainage cross-sectional area of ​​the drain port 1 increases with the increase of the depth of water accumulation in the water tray body.

[0085] The drainage cross-sectional area of ​​the drain port 1 increases with the increase of the depth of the accumulated water in the water receiving pan body, which means that the drainage cross-sectional area of ​​the drain port changes with the change of the depth of the accumulated water. When the depth of the accumulated water increases, the drainage cross-sectional area of ​​the drain port increases. The length direction of the water receiving pan body corresponds to the positive direction of the Y axis in the figure, and the direction of the accumulated water depth corresponds to the positive direction of the Z axis in the figure. The drainage cross-sectional area refers to the actual area occupied by the accumulated water discharged from the water receiving pan body, specifically, a plane is cut in a direction perpendicular to the direction of the accumulated water outflow, and the actual area of ​​the accumulated water on this cut plane that occupies the entire area is the drainage cross-sectional area.

[0086] In this way, the drainage cross-sectional area of ​​the drainage port is increased as the water depth of the water receiving pan body increases, that is, different water depths are set to correspond to drainage ports with different drainage cross-sections, and the change of the drainage port liquid level changes with the change of the water depth of the water receiving pan body, and the water receiving pan body is used to accommodate condensed water that directly drips or slides from the evaporator, so that the water depth of the water receiving pan body can directly reflect the generation speed of condensed water in the air conditioner evaporator. In addition, since different water depths are set to correspond to drainage ports with different drainage cross-sections, the condensed water can be effectively and timely discharged, preventing the generated condensed water from overflowing the water receiving pan body and causing unnecessary losses.

[0087] Since the water tray body is used to hold condensed water that drips or slides directly from the evaporator, the generation rate of condensed water in the air conditioner evaporator is calculated by detecting the water depth position of the water tray, and the speed of condensed water generation is reflected by the water level.

[0088] It should be noted that, under the premise that the amount of water inlet (i.e., the speed of condensing water in the evaporator) remains consistent, as the water level in the water pan rises, the amount of water discharged from the drain outlet will gradually increase, and eventually the balance between water inlet and water discharge will be maintained at a certain water level. Without considering the time scale from the beginning of water inlet to reaching equilibrium, the speed of condensed water generation can be reflected by the height of the water level. In addition, the cross-sectional size of the drain outlet of the air conditioner water pan can be gradually changed according to the different water depth positions. When the water pan is at a low water level, the cross-sectional size of the drain outlet can be set smaller, and when the water pan is at a high water level, the cross-sectional size of the drain outlet can be set larger to speed up the drainage and avoid overflowing.

[0089] Optionally, the water receiving pan body has a receiving space, and a water inlet is provided at the top of the water receiving pan body for condensed water to enter, and the inlet water is directly dripped or slid into the water receiving pan body from the evaporator. The water receiving pan body is used to receive condensed water, and the drain port is used to drain the condensed water in the water receiving pan body. The height of the drain port is lower than the height of the water receiving pan body, and the width of the drain port is smaller than the width of the water receiving pan body, so as to facilitate the rapid discharge of condensed water.

[0090] like Figure 4 and Figure 5 As shown, Figure 4 FIG. 1 is a schematic cross-sectional view of a drain outlet according to an embodiment of the present invention. Figure 1 , Figure 5 FIG. 1 is a schematic cross-sectional view of a drain outlet according to an embodiment of the present invention. Figure 2 . The drainage cross-sectional area of ​​the drain outlet 1 increases with the increase of the depth of water accumulation in the water receiving pan body. Optionally, the drain outlet can be set so that the cross-sectional width of the drain outlet is the same at the top and bottom. Alternatively, the drain outlet can also be set so that the cross-sectional width of the upper drain outlet is narrow and the cross-sectional width of the lower drain outlet is wide. Drain outlets with different drainage cross-sections are set according to different water accumulation depths, wherein the cross-sectional width of the drain outlet corresponds to the positive direction of the X-axis in the figure. In this way, the generated condensed water can be effectively prevented from overflowing the water receiving pan body and causing unnecessary losses.

[0091] Alternatively, if Figure 6 FIG. 1 is a schematic cross-sectional view of a drain outlet according to an embodiment of the present invention. Figure 3 The drain outlet can be arranged so that the cross-sectional width is wide at the top and narrow at the bottom. Specifically, the cross-sectional width of the drain outlet 1 gradually decreases from top to bottom. The direction from top to bottom refers to the direction along the gravity, or can be considered as the direction of the water depth in the water receiving tray body.

[0092] When the water level of the water receiving pan body is low, the cross-sectional width of the drain outlet is small, so that the water level can change rapidly, quickly accumulating from a low water level to a relatively high water level, so that the detection device can quickly identify the water depth position and avoid detection lag; and when the water level of the water receiving pan body is high, the cross-sectional width of the drain outlet is large, which can speed up the drainage speed and avoid water overflow.

[0093] When the cross-sectional width of the drain outlet 1 gradually decreases from top to bottom, specifically, the cross-sectional width of the drain outlet 1 gradually decreases in a step-like manner from top to bottom.

[0094] In this way, the cross-sectional width of the drain port gradually decreases in a step-like manner, which is conducive to providing a certain buffer space for the condensed water, avoiding a strong impact force when the condensed water is discharged, which is difficult to control. By setting the cross-sectional width of the drain port to gradually decrease in a step-like manner, the condensed water can be discharged evenly, which facilitates the discharge control operation of the condensed water.

[0095] The cross-sectional width of the drain outlet 1 is in a stepped shape, which means that each step surface corresponds to a different height, and there is a height difference between the vertices of each adjacent step surface.

[0096] Optionally, when the cross-sectional area of ​​the drain port increases with the depth of water accumulation in the water receiving pan body, different cross-sectional widths correspond to different water accumulation depths. When the cross-sectional width of the drain port 1 gradually decreases from top to bottom, the cross-sectional widths corresponding to the water depth positions L1, L2 and L3 are W1, W2 and W3, respectively. Such a setting speeds up the change of water depth position, quickly identifies condensation risks and avoids detection lag, while ensuring that the condensed water in the water receiving pan body can be discharged in time. Where W1<W2<W3.

[0097] Optionally, the cross-sectional widths of W1, W2 and W3 can be designed according to the condensation water generation rate during the actual operation of the air conditioner. Among them, W1 can be set to 10mm, W2 can be set to 15mm, and W3 can be set to 20mm. In this way, when the water level is low, W1 is set to 10mm, so that the low water level quickly accumulates to a relatively high water level, so that the detection device can quickly identify the water depth position and avoid detection lag; when the water level is between the low water level and the high water level, the corresponding W2 is set to 15mm, which can make the drainage speed relatively faster; and when the water tray body is at a high water level, the cross-sectional width of the drain port is large, and W3 is set to 20mm, which can speed up the drainage speed and avoid water overflow.

[0098] like Figure 7 FIG. 1 is a schematic cross-sectional view of a drain outlet according to an embodiment of the present invention. Figure 4 . Optionally, when the cross-sectional width of the drain outlet 1 gradually decreases from top to bottom, the cross-sectional width of the drain outlet 1 gradually decreases linearly from top to bottom. In this way, since the drain outlet is set to be wide at the top and narrow at the bottom, on the one hand, the detection device can quickly identify the water depth position at a low water level, and can speed up the drainage speed at a high water level to avoid water overflow; on the other hand, it is set to a linear change state, so that such high process precision is not required during the manufacturing process, which reduces the difficulty of the drain outlet design process.

[0099] Optionally, the air conditioner water tray further comprises a water level detection device 4, and the water level detection device 4 is arranged on the water tray body to detect the depth of accumulated water in the water tray body.

[0100] In this way, by providing a water level detection device, it is convenient to grasp the change of the depth of the accumulated water in the water receiving tray body in real time.

[0101] Regarding the arrangement of the water receiving tray body, specifically, the water receiving tray body includes a water storage portion 2 and a detection portion 3 , the drain port 1 is arranged on a side wall of the water storage portion 2 , and the water level detection device is arranged on the detection portion 3 .

[0102] In this way, setting the drain port on the side wall of the water storage part can reduce interference with the detection of the water depth and reduce the detection error of the water depth, and it is convenient to set the drain port. Moreover, by setting the drain port on the side wall of the water storage part, the corresponding relationship between the drainage area and the water depth can be directly established, and the change of the water depth changes with the change of the side wall liquid level, which is convenient for grasping the change of the water depth of the condensed water at any time.

[0103] The space of the water storage part 2 is larger than the space of the detection part 3. There is an inlet for condensed water to flow in at the top of the water storage part 2. The water storage part 2 is used to store the condensed water that flows in. Since the water storage part 2 and the detection part 3 are connected, the accumulated water in the water storage part 2 flows into the detection part 3 through the conductive channel, so that the water levels of the water storage part 2 and the detection part 3 are the same or nearly the same. A detection device is provided in the detection part 3 to detect the depth of accumulated water. Regarding the setting of the drain port, specifically, the drain port 1 is provided on the outer wall of the water storage part 2, and the outer wall is a side wall of the water storage part 2 away from the detection part 3. Since the detection part 3 is used to detect the depth of accumulated water, if the drain port 1 is provided on the side wall of the detection part, it will interfere with the detection of the depth of accumulated water, making the detection result inaccurate, and there is an error between the detected result and the actual result. Therefore, the drain port is provided on the side wall of the water storage part to reduce the interference with the detection of the depth of accumulated water and improve the accuracy of the detection. In addition, the drain outlet is arranged on the same side as the detection part, which facilitates the arrangement of the drain outlet.

[0104] A partition is provided between the water storage portion 2 and the detection portion 3 . Specifically, the water storage portion 2 and the detection portion 3 are separated by a hollow partition 21 .

[0105] In this way, the water storage part and the detection part are separated by a partition, and the partition is designed to be hollowed out to ensure that the water levels of the water storage part and the detection part are consistent, and the partition plays a role of limiting and restraining the floating member. When the depth of the accumulated water is to be detected, since the water levels of the water storage part and the detection part are consistent, when detecting the depth of the accumulated water, it is only necessary to detect the detection part, which is convenient for detecting the depth of the accumulated water.

[0106] The water storage part 2 and the detection part 3 are separated by a partition 21, which divides the water receiving tray body into two areas, the left area is the water storage area of ​​the water receiving tray body, and the right area is the detection area. The partition is set to be hollow so that the accumulated water in the water storage part 2 and the accumulated water in the detection part 3 can flow to ensure that the water levels of the water storage part and the detection part are consistent, which is convenient for the detection part to detect the depth of accumulated water.

[0107] Optionally, the water level detection device 4 includes a floating member 41 , which is disposed on the detection portion 3 , and a position of the floating member 41 is consistent with a water surface of the detection portion 3 .

[0108] In this way, a floating member is provided in the detection part, and the position of the floating member is consistent with the water surface of the detection part. The floating member is used to display the water level, so as to grasp the change of the depth of the accumulated water.

[0109] The floating member 41 partially floats on the water surface of the detection part 3. The floating member 41 can be a float placed in the detection part. The float is made of a low-density material or a hollow structure and can float on the water surface. The position of the float is consistent with the water level in real time.

[0110] The length and width of the floating member 41 are equal or nearly equal to the length and width of the detection part 3, and the height of the floating member 41 is different from the height of the detection part 3. The floating member 41 floats up and down as the water level of the detection part 3 changes. By setting the length and width of the floating member 41 equal or nearly equal to the length and width of the detection part 3, the detection part 3 restricts the floating member 41 to move within a certain area, which can prevent the floating member from shaking, and avoid the shaking of the floating member causing poor contact with other structures of the water level detection device, which is not conducive to the detection of the depth of accumulated water.

[0111] Specifically, one side of the floating member 41 contacts the inner wall of the detection part 3 .

[0112] In this way, one side of the floating member contacts the inner wall of the detection portion to conduct the water level detection circuit, thereby facilitating the detection of the depth of accumulated water.

[0113] like Figure 8 and Fig. 9 As shown, Figure 8 is a schematic diagram of the structure of a floating member according to an embodiment of the present invention, Fig. 9 Schematic diagram of the structure of a floating member according to another embodiment of the present invention. Optionally, the water level detection device 4 further includes a conductive structure 42 and a water level detection circuit 43, wherein the conductive structure 42 is arranged on the side where the floating member 41 contacts the inner wall of the detection part 3, and the water level detection circuit 43 is arranged at a corresponding position on the inner wall where the detection part 3 contacts the floating member 41.

[0114] In this way, a conductive structure is provided on the side of the floating member that contacts the inner wall of the detection part, and the water level detection circuit is turned on through the conductive structure, so as to facilitate the detection of the depth of the accumulated water. When the conductive structure is metal, it should be noted that due to the obvious difference in the conductivity of metal and water, when the current is small, the conductive effect of water is very weak, and the water and the water level detection circuit will not be turned on. For example, copper is taken as an example of metal, where the conductivity of copper is 59.6×106S / m, and the conductivity of water is 0.005S / m. The conductivity of copper is much greater than the conductivity of water. It can be seen that there is an order of magnitude difference between the conductivity of metal and the conductivity of water. Generally speaking, the so-called water level detection circuit is in a conductive state, which means that when the current of the branch where the water level detection circuit is located reaches a preset current threshold, the water level detection circuit is considered to be in a conductive state, and when the current value does not reach the current threshold, it can be considered to be non-conductive. In this embodiment, in order to achieve that the water is not conducting with the water level detection circuit, while the metal is conducting with the water level detection circuit, this can be achieved by increasing the conduction current threshold. Since there is an order of magnitude difference between the conductivity of the metal and the conductivity of the water, a suitable current threshold is set so that the metal can be conducting with the water level detection circuit, while the water and the water level detection circuit are considered to be non-conducting. Based on the above technical principles, the conduction process of the water level detection circuit is as follows: when the floating member floats up and down with the change of the water level, since the floating member and the conductive structure are an integrated structure, the conductive structure moves up and down with the conductive structure. In the process of the conductive structure moving up and down, it may contact the water level detection circuit at a certain height. When the conductive structure contacts the water level detection circuit at a certain height, the water level detection circuit is turned on, thereby detecting the depth of the accumulated water.

[0115] The conductive structure may be a metal sheet, and a metal sheet is provided on the side of the floating member in contact with the inner wall of the detection unit, and the water level detection circuit is conducted through the metal sheet, thereby realizing the detection of the depth of accumulated water. Of course, it is also possible to provide other conductive structures on the side of the floating member in contact with the inner wall of the detection unit, as long as they can conduct the water level detection circuit.

[0116] Optionally, in addition to the method of the previous embodiment, the conduction of the water level detection circuit can also be achieved in other ways, such as replacing the metal sheet with a hard material (as long as it is hard and conductive), and providing a waterproof coating on the trigger point of the water level detection circuit, so that the hard material contacts the waterproof coating of the trigger point, that is, the internal trigger point can be triggered by the waterproof coating, thereby conducting the water level detection circuit. The conduction process of the water level detection circuit is as follows: due to the provision of a waterproof coating, when the floating part drives the hard material to move up and down with the change of the water level, the hard material contacts the waterproof coating of the water level detection circuit at a certain height and squeezes the waterproof coating. The waterproof coating is deformed due to being squeezed, thereby making the internal circuit conductive, thereby achieving the conduction of the water level detection circuit. For example, the implementation method of making the internal circuit conductive by the deformation of the waterproof coating can be that a trigger switch is set inside the water level detection circuit. When the waterproof coating is not squeezed, the trigger switch of the water level detection circuit is in an open state, and when the waterproof coating is deformed due to squeezing, the trigger switch is in a closed state, so that the water level detection circuit is turned on. In order to ensure the conductive effect of the water level detection circuit, the length of the hard material is designed to be at least greater than the height difference between adjacent water level detection circuits and less than the maximum height difference between three adjacent water level detection circuits, so as to ensure that the water level detection circuit can be turned on at any position. Optionally, when the floating member itself is a hard material, there is no need for an additional conductive structure to trigger the water level detection circuit. At this time, the length of the floating member needs to meet the requirement that the length of the area where the floating member and the waterproof coating may contact is at least greater than the height difference between adjacent water level detection circuits and less than the maximum height difference between three adjacent water level detection circuits, so as to ensure that the water level detection circuit can be turned on at any position.

[0117] Optionally, a plurality of the water level detection circuits 43 are arranged vertically on the inner wall of the detection portion 3 and the water level detection circuits 43 are conductive after contacting with the conductive structure 42 .

[0118] In this way, water level detection circuits are set up at different water level heights to facilitate the detection of water depths at different heights. When the water depths are different, only a very small number of water level detection circuits are set up, which will cause large errors in the detection data during the detection process, which is not conducive to the real-time detection of the water depth.

[0119] The plurality of water level detection circuits are arranged at equal intervals inside the detection unit along the direction of the accumulated water depth, and each water level detection circuit corresponds to a different water level height. A water level detection circuit may not be provided at the lowest water level height, and a positioning detection circuit may be provided at the highest water level height.

[0120] The multiple water level detection circuits include three or more water level detection circuits. For example, there are four water level detection circuits. The water level heights corresponding to the four water level detection circuits are different. The four water level detection circuits can be arranged at equal intervals along the vertical direction. The lowest water level is L0, and no water level detection circuit is arranged at the lowest water level. The height corresponding to the first water level detection circuit is L1, the height corresponding to the second water level detection circuit is L2, the height corresponding to the third water level detection circuit is L3, and the height corresponding to the fourth water level detection circuit is L4, where L4 corresponds to the upper limit water level. Among them, L1<L2<L3<L4, where L1 can be 5mm, L2 can be 10mm, and L3 can be 15mm. The heights of L1, L2 and L3 are based on the lowest water level, and no water level detection circuit can be arranged at the lowest water level.

[0121] The conductive structure takes a metal sheet as an example. Regarding the setting of the length of the metal sheet, the length of the metal sheet is greater than the height difference between adjacent water level detection circuits 43 .

[0122] Thus, when the metal sheet is located between adjacent water level detection circuits, the metal sheet fails to contact and conduct with any water level detection circuit, and thus the data of the water depth cannot be detected. By setting the length of the metal sheet to be greater than the height difference between the adjacent water level detection circuits, the situation where the metal sheet is located between adjacent water level detection circuits can be avoided, thereby ensuring that the water level detection circuit can be conducted at any position of the metal sheet, which is convenient for detecting the water depth.

[0123] Among them, the shortest length of the metal sheet is at least greater than the height difference between the adjacent water level detection circuits 43. Taking four water level detection circuits as an example, the four water level detection circuits are arranged at equal intervals. The height difference between the two adjacent water level detection circuits is the height difference between the lowest water level L0 and L1, or the height difference between L2 and L1, or the height difference between L3 and L2, or the height difference between L4 and L3. The length of the metal sheet is set to be at least greater than the height difference between the adjacent water level detection circuits to ensure that the corresponding water level detection circuit is turned on. If the length of the metal sheet is less than or equal to the height difference between the adjacent water level detection circuits, when the metal sheet is located exactly between the adjacent water level detection circuits, the metal sheet will not be able to abut and conduct with any water level detection circuit because the length is not long enough, so that the data of the depth of water accumulation cannot be detected, which is not conducive to the detection of the depth of water accumulation. Therefore, the length of the metal sheet is set to be at least greater than the height difference between the adjacent water level detection circuits to ensure that the water level detection circuit is turned on at any position.

[0124] The length of the metal sheet is not necessarily longer, but needs to be limited to a certain length range. Specifically, the length of the metal sheet is smaller than the maximum height difference between three adjacent water level detection circuits 43 .

[0125] In this way, the length of the metal sheet is smaller than the maximum height difference between three adjacent water level detection circuits, so as to reduce the detection interference caused by the simultaneous conduction of multiple water level detection circuits.

[0126] Still taking the example of four water level detection circuits, the three adjacent water level detection circuits refer to the height difference between the lowest water levels L0 and L2, or the height difference between L1 and L3, or the height difference between L2 and L4.

[0127] The floating member 41 may be a float. When the water level in the water receiving tray body is at the water depth position L1, L2, L3 or L4, the metal sheet on the float turns on the water level detection circuit corresponding to the water depth position L1, L2, L3 or L4, and the air conditioner controller identifies the actual water depth position of the current water receiving tray by detecting the signal value such as the current or voltage of the corresponding detection circuit. When the float is in a position where the detection circuits of adjacent water levels are turned on at the same time, the controller receives the detection circuit signals of two water levels at the same time. At this time, the controller takes the detected high water level signal as the standard and controls according to the high water level signal.

[0128] An embodiment of the present invention provides an air conditioner, which includes the air conditioner water receiving tray as described above.

[0129] In this way, the drainage cross-sectional area of ​​the drainage port is increased as the water depth of the water receiving pan body increases, that is, different drainage cross-sectional drainage ports are set corresponding to different water accumulation depths, and the change of the drainage port liquid level changes with the change of the water accumulation depth of the water receiving pan body, and the water receiving pan body is used to accommodate condensed water that directly drips or slides from the evaporator, so that the water accumulation depth of the water receiving pan body can reflect the generation speed of condensed water in the air conditioner evaporator to a certain extent. In addition, since different drainage cross-sectional drainage ports are set corresponding to different water accumulation depths, the condensed water can be effectively and timely discharged, preventing the generated condensed water from overflowing the water receiving pan body and causing unnecessary losses.

[0130] like Fig.10 As shown, Fig.10 The flowchart of the air conditioner anti-condensation control method according to an embodiment of the present invention. The embodiment of the present invention also discloses an air conditioner anti-condensation control method, the air conditioner includes the air conditioner water receiving tray described above, and the anti-condensation control method includes:

[0131] S100, in cooling mode, obtaining water level data of the water level detection device 4 of the water receiving pan of the air conditioner.

[0132] The water level data is obtained by detecting the water level detection device 4 of the air conditioner water pan as described above.

[0133] S200, obtaining current operating parameters of the air conditioner.

[0134] Wherein, the operating parameter of the air conditioner may be a compressor frequency or an internal fan speed.

[0135] S300, determining the water depth of the water receiving pan of the air conditioner according to the water level data, and adjusting the operating parameters according to the water depth of the water receiving pan of the air conditioner.

[0136] Among them, the difficulty of current air condensation can be judged more intuitively according to the water accumulation depth of the air conditioner water tray, and then the operating parameters of the air conditioner can be adjusted to perform anti-condensation control.

[0137] In this way, water level data is obtained through the water level detection device of the air conditioner water tray, thereby obtaining the water accumulation depth of the water tray. The water tray is used to hold condensed water that drips or slides directly from the evaporator. The water accumulation depth of the water tray body reflects the speed of condensation water generation, thereby determining the difficulty of condensation generation at the air outlet of the air conditioner in the current environment, and then adjusting the operating parameters of the air conditioner for advance control, thereby effectively avoiding the formation of condensation water droplets around the air outlet of the air conditioner.

[0138] The speed of condensation water generation in the air conditioner evaporator can be calculated by detecting the water depth in the water tray, and the speed of condensation water generation can be reflected by the water level, so as to determine the difficulty of condensation generation at the air conditioner outlet in the current environment. Then, the compressor frequency and internal fan speed of the air conditioner can be controlled in advance, which can effectively avoid the formation of condensation droplets around the air conditioner outlet.

[0139] Under the premise that the water inflow (i.e. the speed of condensation of the evaporator) remains the same, as the water level in the water tray rises, the drainage volume of the drain outlet will gradually increase, and eventually the balance between water inflow and drainage will be maintained at a certain water level. That is, the speed of condensation water generation can be reflected by the water level.

[0140] Compared with judging condensation by humidity value, this solution does not need to use humidity sensor. In fact, judging condensation by temperature and humidity is also an indirect judgment. The present invention can judge the difficulty of current air condensation more intuitively by water level, and then perform anti-condensation control to avoid condensation formation.

[0141] like Fig.11 As shown, Fig.11 Flow chart of an air conditioner anti-condensation control method according to another embodiment of the present invention. Optionally, the step S300, determining the water depth of the air conditioner water tray according to the water level data, and adjusting the operating parameters according to the water depth of the air conditioner water tray, includes:

[0142] S310: Determine the water accumulation depth according to the water level data.

[0143] The water level data is detected by a water level detection device in the water tray of the air conditioner, and the current water depth is determined by the water level data.

[0144] S320, determining whether the accumulated water depth exceeds a first water level threshold.

[0145] Among them, when the depth of accumulated water corresponds to the first water level threshold, the speed of condensed water generation is slow and the depth of accumulated water is shallow, which means that condensation is not easy to generate at the air outlet of the air conditioner in the current environment. Since condensation is not easy to generate at the current air outlet of the air conditioner, the exceeding here means that when the depth of accumulated water is greater than the first water level threshold, it is considered to exceed the first water level threshold. If the depth of accumulated water is less than or equal to the first water level threshold, it is considered that the depth of accumulated water does not exceed the first water level threshold. The first water level threshold is L1, and L1 can be 5mm. At this time, when the depth of accumulated water is less than or equal to 5mm, it is considered that condensation is not easy to generate at the air outlet of the current environment and is within a safe range.

[0146] S330, if the water depth does not exceed the first water level threshold, control the air conditioner to operate according to the current operating parameters, and re-execute S100 to obtain water level data of the water level detection device of the water tray of the air conditioner.

[0147] When the water depth is less than or equal to L1, the current internal fan speed and compressor frequency of the air conditioner remain unchanged and continue to operate. Then, after a preset time period, the water level data of the water level detection device of the air conditioner water tray as described above is obtained again, so as to grasp the current condensation water generation speed in real time, judge the difficulty of condensation formation at the air outlet, control the air conditioner compressor frequency and internal fan speed and other parameters in advance, and avoid the formation of condensation water droplets around the air outlet of the air conditioner.

[0148] In this way, when the depth of accumulated water does not exceed the first water level threshold, it means that the speed of condensation water generation is relatively slow and still within a safe range, and the operating parameters are relatively appropriate. In addition, by re-acquiring the water level data of the water level detection device of the air conditioner water tray, the depth of accumulated water is detected in real time, which facilitates timely adjustment of the operating parameters of the air conditioner.

[0149] Optionally, if the water accumulation depth exceeds the first water level threshold, the compressor frequency in the operating parameters of the air conditioner is reduced.

[0150] In this way, when the water accumulation depth is greater than the first water level threshold, the compressor frequency is reduced, and the refrigeration function is reduced to slow down the generation rate of condensation water, effectively prevent condensation generation, and improve user experience.

[0151] Optionally, the step S300 of determining the water depth of the air conditioner water tray according to the water level data and adjusting the operating parameters according to the water depth of the air conditioner water tray further includes:

[0152] S340: If the water accumulation depth exceeds the first water level threshold, determine whether the water accumulation depth exceeds a second water level threshold, and the second water level threshold is greater than the first water level threshold.

[0153] Among them, when the water depth corresponds to the second water level threshold, the speed of condensation water generation is relatively fast, and the water depth becomes slightly deeper, but it is still within a relatively controllable range. The speed of condensation generation at the air outlet of the air conditioner in the current environment is medium. When the water depth is greater than the first water level threshold, then determine whether the water depth is greater than the second water level threshold. The second water level threshold is L2, and L2 can be 10mm. The exceeding here means that when the water depth is greater than L2, it is considered to be exceeded. When the water depth is less than or equal to L2, it is considered not to be exceeded.

[0154] S350: If the water accumulation depth does not exceed the second water level threshold, reducing the compressor frequency in the operating parameters of the air conditioner by a first frequency.

[0155] Among them, when the water depth is less than or equal to L2, the compressor frequency in the air conditioner is reduced. The reduction is to reduce the first frequency based on the currently running compressor frequency. The first frequency can be 5HZ. For example, the current compressor frequency is F. When the water depth is greater than L1 and less than or equal to L2, the compressor frequency is adjusted to F-5HZ. It should be noted that, if the compressor frequency F is lower than the minimum operating frequency Fmin, the current frequency is kept unchanged at Fmin, and Fmin can be 20HZ.

[0156] In this way, when the water accumulation depth is between the first water level threshold and the second water level threshold, the compressor frequency is reduced, and the refrigeration function is reduced to slow down the generation rate of condensation water, effectively prevent condensation generation, and improve user experience.

[0157] Among them, it should be noted that since the current application scenario is to achieve the windless function, in order to achieve the windless function, when the water depth is within a relatively safe depth range, the compressor frequency is adjusted to reduce the speed of condensation water generation. Of course, according to actual needs, in order to prevent condensation generation, it can be achieved not only by adjusting the compressor frequency, but also by adjusting the internal fan speed, or by adjusting the compressor frequency and the internal fan speed at the same time.

[0158] Optionally, the step S300 of determining the water depth of the air conditioner water tray according to the water level data and adjusting the operating parameters according to the water depth of the air conditioner water tray further includes:

[0159] S360: If the water accumulation depth exceeds the second water level threshold, the compressor frequency is reduced by a second frequency; the second frequency is greater than the first frequency.

[0160] The exceeding here means that only when the water depth is greater than the second water level threshold, it is considered to be exceeding. When the water depth is greater than L2, the compressor frequency is reduced, and the specific compressor frequency is less than the current compressor frequency by a second frequency, and the second frequency can be 10HZ.

[0161] S370, determining whether the accumulated water depth exceeds a third water level threshold, wherein the third water level threshold is greater than the second water level threshold.

[0162] Among them, when the water depth corresponds to the third water level threshold, the speed of condensation water generation is very fast, and the current water depth is deep, indicating that condensation is easy to form at the air outlet of the air conditioner in the current environment. The exceeding here also means that it is considered to be exceeded only when the water depth is greater than the third water level threshold. The third water level threshold is L3, and the value of L3 can be 15mm.

[0163] S380: If the water depth does not exceed the third water level threshold, the speed of the internal fan in the operating parameters of the air conditioner is increased by a first speed.

[0164] Among them, when the water depth is less than or equal to the third water level threshold, the internal fan speed of the air conditioner is increased, specifically the first speed is increased, and the first speed can be 50 rpm. It should be noted that if the internal fan speed R is higher than the maximum operating speed Rmax, the current speed is kept unchanged at Rmax, and Rmax can be 1100 rpm.

[0165] In this way, when the water depth exceeds the second water level threshold, the cooling capacity is reduced by reducing the compressor frequency to a second frequency with a larger amplitude, so that the generation rate of condensation water is slowed down; and when the water depth is between the second water level threshold and the third water level threshold, the water depth is relatively large and the generation rate of condensation water is relatively fast. By increasing the speed of the internal fan and reducing the refrigeration function, the generation rate of condensation water is slower.

[0166] Optionally, the step S300 of determining the water depth of the air conditioner water tray according to the water level data and adjusting the operating parameters according to the water depth of the air conditioner water tray further includes:

[0167] S390: If the water depth exceeds the third water level threshold, the rotation speed of the internal fan is increased to a second rotation speed; the second rotation speed is greater than the first rotation speed.

[0168] When the water depth is greater than the third water level threshold, the speed of the internal fan is adjusted to increase the speed of the internal fan to a second speed, which can be 100 rpm. It should be noted that if the speed R of the internal fan is higher than the maximum operating speed Rmax, the current speed is kept unchanged at Rmax, which can be 1100 rpm.

[0169] In this way, when the water depth exceeds the third water level threshold, the water depth is close to the maximum water level. By increasing the speed of the internal fan, and setting the second speed to be greater than the first speed, the speed of condensation water generation is slowed down to prevent condensation water from overflowing. Of course, considering that the water depth is close to the upper water level, in order to prevent condensation water from overflowing, the compressor frequency can be adjusted while adjusting the speed of the internal fan.

[0170] It should be noted that S100, S200, S300, etc. represent corresponding steps 100, 200, and 300, wherein the order of the steps here does not represent a limitation on the execution order.

[0171] like Fig.12 As shown, it is a flow chart of an air conditioner anti-condensation control method according to another embodiment of the present invention. Optionally, in S350, if the water depth does not exceed the second water level threshold, the compressor frequency in the operating parameters of the air conditioner is reduced by a first frequency, and after a preset time, S100 is re-executed to obtain the water level data of the water level detection device 4 of the air conditioner water tray.

[0172] Optionally, in S380, if the water accumulation depth does not exceed the third water level threshold, the internal fan speed in the operating parameters of the air conditioner is increased by the first speed, and after a preset time, S100 is re-executed to obtain the water level data of the water level detection device 4 of the water tray of the air conditioner.

[0173] Optionally, in S390, if the water accumulation depth exceeds the third water level threshold, the rotation speed of the internal fan is increased to the second rotation speed, and after a preset time, S100 is re-executed to obtain the water level data of the water level detection device 4 of the air conditioner water tray.

[0174] In this way, by re-circulating and acquiring the water level data of the water level detection device of the air conditioner water tray after a preset time period, the depth of accumulated water can be detected in real time, which facilitates real-time adjustment of the operating parameters of the air conditioner and avoids the formation of condensation droplets around the air outlet of the air conditioner.

[0175] Optionally, when adjusting the operating parameters of the air conditioner, the compressor frequency or the internal fan speed may be adjusted separately according to actual needs, or the compressor frequency and the internal fan speed may be adjusted simultaneously.

[0176] like Fig.13 As shown, it is a structural block diagram of a control device for an air conditioner according to an embodiment of the present invention. The embodiment of the present invention also discloses a control device for an air conditioner, the air conditioner includes the air conditioner water receiving tray described above, and the control device for the air conditioner includes:

[0177] An acquisition unit 10 is used to acquire water level data of the water level detection device 4 of the water receiving pan of the air conditioner in cooling mode;

[0178] A detection unit 20, which is used to obtain the current operating parameters of the air conditioner;

[0179] The adjustment unit 30 is used to determine the water depth of the air conditioner water tray according to the water level data, and adjust the operating parameters according to the water depth of the air conditioner water tray.

[0180] In this way, water level data is obtained through the water level detection device of the air conditioner water tray, thereby obtaining the water accumulation depth of the water tray. The water tray is used to hold condensed water that drips or slides directly from the evaporator. The water accumulation depth of the water tray body reflects the speed of condensation water generation, thereby determining the difficulty of condensation generation at the air outlet of the air conditioner in the current environment, and then adjusting the operating parameters of the air conditioner for advance control, thereby effectively avoiding the formation of condensation water droplets around the air outlet of the air conditioner.

[0181] Furthermore, the adjustment unit 30 is used to determine the water accumulation depth based on the water level data, and judge whether the water accumulation depth exceeds a first water level threshold; if the water accumulation depth does not exceed the first water level threshold, the air conditioner is controlled to operate according to the current operating parameters, and the water level data of the water level detection device 4 of the air conditioner water tray is re-acquired.
