Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to a water pumping device, a portable air conditioner, and an air conditioner control method. Background Technology

[0002] Currently, with the development of science and technology and the improvement of living standards, traditional split-type air conditioners, whose indoor and outdoor units are connected by copper pipes, can no longer meet users' outdoor needs due to their difficult installation, large size, and inability to move. Correspondingly, new portable air conditioners with integrated structures have gained popularity among users due to their advantages of high comfort, multi-functionality, and portability.

[0003] In existing technologies, because portable air conditioners need to be placed in specific usage scenarios (such as tents, desktops, etc.), their drainage design (mainly condensate) has become a problem. The drainage methods already in use can be broadly divided into two types:

[0004] Method 1: Add a float sensor to the water tray inside the portable air conditioner. The float sensor is connected to the main board terminal. When the water level in the water tray reaches the set maximum water level, the float sensor will send a signal to the main board to stop the machine and alarm the user to manually drain the water. This can prevent water damage to large electrical components caused by overflowing condensate from the water tray.

[0005] Method 2: Add a water pump motor directly to the internal water tray of the portable air conditioner. The water pump motor drives the water pump wheel to rotate, so as to disperse the condensate water of the evaporator onto the condenser fins for evaporation, thereby achieving uninterrupted discharge of condensate water.

[0006] However, all of the above drainage methods have certain drawbacks. For example, in method one, the user manually drains the water frequently, which can easily cause the portable air conditioner to stop working during the user's rest period, thus affecting the user experience. In method two, although the continuous operation of the water wheel can ensure the continuous discharge of condensate, its operating noise is relatively loud, which also affects the user experience. Summary of the Invention

[0007] The main objective of this invention is to provide a water-discharging device, a portable air conditioner, and an air conditioner control method to solve the problem that the drainage method of portable air conditioners in the prior art affects the user experience.

[0008] To achieve the above objectives, according to one aspect of the present invention, a water-spraying device is provided, disposed within an air conditioner body. The water-spraying device includes: a water-spraying structure rotatably disposed, the water-spraying structure having a water-spraying protrusion for spraying liquid on a water receiving tray located in the air conditioner body onto the condenser of the air conditioner body during rotation of the water-spraying structure; a driving device drivenly connected to the water-spraying structure to drive the water-spraying structure to rotate; a detection element disposed on the water receiving tray to detect the liquid level height value on the water receiving tray, and to control at least one of the rotational speed or direction of the driving device according to the detection value of the detection element; and / or, to control the detection element to be powered on or off according to the detection value of the detection element.

[0009] Furthermore, the water-spraying structure has a container for containing liquid, which is disposed between the water-spraying protrusion and the rotation axis of the water-spraying structure.

[0010] Furthermore, the water-spraying structure also includes: a wheel-shaped main body, which is driven and connected to a driving device, and a water-spraying protrusion disposed on the outer peripheral surface of the wheel-shaped main body; wherein, the water-spraying protrusion has at least two opposing first side surfaces in the direction of the central axis of the wheel-shaped main body, and the distance between the at least two first side surfaces gradually increases along the direction from the water-spraying protrusion to the central axis of the wheel-shaped main body to form a water-spraying surface for striking the liquid surface.

[0011] Furthermore, the first side has a water-breaking area, and the distance between at least two water-breaking areas gradually increases in the opposite direction of the rotation direction of the wheel-shaped body, so as to form a water-breaking part on the water-spraying surface for breaking the liquid surface.

[0012] Furthermore, the receiving part is a strip-shaped hole, which is arc-shaped and located on the side of the wheel-shaped main body. The protruding direction of the strip-shaped hole is opposite to the rotation direction of the water-spraying structure. There are multiple receiving parts, which are spaced apart around the rotation axis of the wheel-shaped main body.

[0013] According to another aspect of the present invention, a portable air conditioner is provided. The portable air conditioner includes an air conditioner body and a water-spraying device. The detection element and the driving device of the water-spraying device are both connected to the control module of the air conditioner body. The control module controls at least one of the rotation speed or direction of the driving device according to the detection value of the detection element; and / or controls the detection element to be powered on or off according to the detection value of the detection element. The water-spraying structure of the water-spraying device is located in the water receiving tray of the air conditioner body. The bottom wall of the water receiving tray is an arc-shaped surface and has a confluence point. The height of the bottom wall of the water receiving tray gradually decreases along the direction from the outer peripheral surface of the water receiving tray to the confluence point. The water-spraying device is the water-spraying device described above.

[0014] Furthermore, the junction is located below the condenser assembly of the air conditioner body, the condenser assembly includes at least two oppositely arranged condensers, the at least two oppositely arranged condensers surround to form a receiving space; wherein, the water pumping structure of the water pumping device is located within the receiving space.

[0015] According to one aspect of the present invention, an air conditioner control method is provided, applicable to the aforementioned portable air conditioner, the air conditioner control method comprising:

[0016] Obtain the test values ​​of the test components of the water dispensing device of a portable air conditioner;

[0017] Determine the magnitude relationship between the detected value and the first preset value, the second preset value, and the third preset value;

[0018] If the detected value is less than or equal to the first preset value, the drive device of the water pumping device will stop running.

[0019] If the detected value is greater than the first preset value and less than or equal to the second preset value, the drive device is controlled to drive the water-spraying structure of the water-spraying device to rotate.

[0020] If the detected value is greater than the third preset value, the control drive device will stop running and the drainage indicator device of the portable air conditioner will be activated.

[0021] Furthermore, after controlling the drive unit to stop operating and controlling the drain indicator device of the portable air conditioner to operate, the air conditioner control method also includes:

[0022] The control sensor is powered on at a first preset time T1 to switch the sensor to intermittent detection mode. The sensor in intermittent detection mode detects the liquid level once at a first preset time T1.

[0023] If the detection value of the detection device in the intermittent detection mode is less than or equal to the first preset value or the second preset value, the detection device is controlled to continue to be powered on and the detection value of the detection device is reacquired.

[0024] If the detection value of the detection device in intermittent detection mode is greater than the third preset value multiple times within the second preset time T2, the portable air conditioner will be controlled to switch to standby mode.

[0025] Furthermore, the air conditioner control method also includes: after the detected value is less than or equal to a first preset value and the control drive device stops running, reacquiring the detected value of the detection element; after the detected value is greater than the first preset value and less than or equal to a second preset value, and the control drive device drives the water-spraying structure to rotate for a third preset time T3, reacquiring the detected value of the detection element.

[0026] Furthermore, the method for determining the magnitude relationship between the detected value and the third preset value includes: reacquiring at least two consecutive detected values ​​of the detected component; if both consecutive detected values ​​are greater than the third preset value, then the detected value is determined to be greater than the third preset value; if any consecutive detected value is less than or equal to the third preset value, then the detected value of the detected component is reacquiring; and / or, the air conditioner control method further includes: if the detected value is greater than the second preset value and less than or equal to the third preset value, then the control drive device is stopped.

[0027] According to the technical solution of the present invention, the water-spraying device is installed inside the air conditioner body. The water-spraying structure of the water-spraying device is rotatably installed. The water-spraying structure has a water-spraying protrusion. The water-spraying protrusion is used to strike the liquid on the water receiving tray of the air conditioner body onto the condenser of the air conditioner body during the rotation of the water-spraying structure. The driving device is drivenly connected to the water-spraying structure to drive the water-spraying structure to rotate. The detection element is installed on the water receiving tray to detect the liquid level height value on the water receiving tray. The driving device is controlled to operate at least one of the following based on the detection value: the rotation speed or the direction of the driving device; and / or, the detection element is powered on or off based on the detection value. Thus, the portable air conditioner using the water-discharging device described in this application can, on the one hand, use the water-discharging structure to push the condensate on the drip tray onto the condenser, continuously and stably discharging the condensate from the drip tray to the air conditioner body through evaporation, thereby reducing the frequency of manual drainage by the user and initially improving the user experience; on the other hand, by controlling the detection element and the drive device for driving the water-discharging structure to rotate according to the detection value (liquid level), it can not only prevent the water-discharging structure from spinning idly when the water level is too low, causing it to emit large airflow noise, but also prevent the detection element from being damaged by water when the water level is too high, thereby reducing the operating noise of the portable air conditioner, improving the operational stability of the water-discharging device, further improving the user experience, and thus solving the problem that the drainage method of portable air conditioners in the prior art affects the user experience.

[0041] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0043] To address the issue that the drainage method of existing portable air conditioners affects the user experience, this application provides a water pumping device, a portable air conditioner, and an air conditioner control method.

[0044] like Figures 1 to 7As shown, the water-spraying device is installed inside the air conditioner body 200. The water-spraying device includes: a water-spraying structure 10, which is rotatably arranged and has a water-spraying protrusion 11. The water-spraying protrusion 11 is used to spray liquid on the water receiving tray 210 of the air conditioner body 200 onto the condenser 220 of the air conditioner body 200 during the rotation of the water-spraying structure 10; a drive device 20, which is drivenly connected to the water-spraying structure 10 to drive the water-spraying structure 10 to rotate; a detection element 30, which is arranged on the water receiving tray 210 to detect the liquid level height value on the water receiving tray 210, and to control at least one of the rotation speed or direction of the drive device 20 according to the detection value of the detection element 30; and / or to control the detection element 30 to be powered on or off according to the detection value of the detection element 30.

[0045] Applying the technical solution of this embodiment, the water-spraying device is installed inside the air conditioner body 200. The water-spraying structure 10 of the water-spraying device is rotatably installed. The water-spraying structure 10 has a water-spraying protrusion 11, which is used to spray the liquid on the water receiving tray 210 of the air conditioner body 200 onto the condenser 220 of the air conditioner body 200 during the rotation of the water-spraying structure 10. The driving device 20 is drivenly connected to the water-spraying structure 10 to drive the water-spraying structure 10 to rotate. The detection element 30 is installed on the water receiving tray 210 to detect the liquid level height value on the water receiving tray 210, so as to control at least one of the rotation speed or direction of the driving device 20 according to the detection value of the detection element 30; and / or, to control the detection element 30 to be powered on or off according to the detection value of the detection element 30. Thus, the portable air conditioner using the water-discharging device in this embodiment can, on the one hand, use the water-discharging structure 10 to push the condensate on the water tray 210 onto the condenser 220, continuously and stably discharging the condensate from the water tray 210 to the outside of the air conditioner body 200 through evaporation, thereby reducing the frequency of manual drainage by the user and initially improving the user experience; on the other hand, by controlling the detection element 30 and the drive device 20 for driving the water-discharging structure 10 to rotate according to the detection value (liquid level) of the detection element 30, it can not only avoid the water-discharging structure 10 from spinning idly when the water level is too low, causing it to emit large airflow noise, but also prevent the detection element 30 from being damaged by water when the water level is too high, thereby reducing the operating noise of the portable air conditioner, improving the operating stability of the water-discharging device, further improving the user experience, and thus solving the problem that the drainage method of portable air conditioners in the prior art affects the user experience.

[0046] In this embodiment, the detection element 30 is a probe-type water level sensor, which has a probe 31 that can be inserted into the liquid to detect the liquid level.

[0047] In other embodiments not shown in the accompanying drawings, the detection element 30 may also be a three-probe water level sensor, wherein the three probes can detect whether there is water at the first preset value, the second preset value and the third preset value respectively, so as to indirectly determine the liquid level height range.

[0048] In this embodiment, the air conditioner body 200 also has a chassis 240, a water receiving tray 210 is disposed on the chassis 240, and the chassis 240 is provided with a mounting recess for fixing the drive device 20.

[0049] Optionally, the drive unit 20 is a servo motor.

[0050] Specifically, the detection element 30 can be positioned close to the water spraying structure 10 to ensure that the detection value of the detection element 30 is as close as possible to the liquid level value at the water spraying structure 10.

[0051] Specifically, the water splashed by the water-spraying structure 10 falls onto the fins of the condenser 220. During the heat exchange process in the condenser 220, the liquid evaporates through the condenser and flows out of the air conditioner body 200 with the internal airflow, thus achieving the discharge of condensate. At the same time, the low-temperature condensate can also promote heat exchange in the condenser 220, thereby improving the heat exchange efficiency of the condenser.

[0052] like Figure 4 and Figure 5 As shown, the water-spraying structure 10 has a receiving portion 12 for containing liquid, which is disposed between the water-spraying protrusion 11 and the rotation axis of the water-spraying structure 10. Thus, when the protrusion 11 is immersed in water, the receiving portion 12 allows water to flow into it, and during the rotation of the water-spraying structure 10, the water splashes, forming a water film on the outer surface of the water-spraying structure 10, thereby improving the water-spraying effect of the water-spraying structure 10.

[0053] like Figures 4 to 6 As shown, the water-spraying structure 10 also has a wheel-shaped body 13, which is driven and connected to the drive device 20. A water-spraying protrusion 11 is disposed on the outer circumferential surface of the wheel-shaped body 13. The water-spraying protrusion 11 has at least two opposing first side surfaces 111 along the central axis of the wheel-shaped body 13. The distance between the at least two first side surfaces 111 gradually increases along the direction from the water-spraying protrusion 11 to the central axis of the wheel-shaped body 13, forming a water-spraying surface 112 for striking the liquid surface. This arrangement of the water-spraying surface 112 reduces the instantaneous shear force when the water-spraying protrusion 11 strikes the liquid surface, thereby reducing the disturbance of the water-spraying protrusion 11 to the liquid, reducing the collision noise between the water-spraying structure 10 and the liquid surface during high-speed rotation, and further improving the user experience.

[0054] In this embodiment, the wheel-shaped body 13 is circular.

[0055] In this embodiment, the wheel-shaped body 13 is also provided with a connecting recess for connecting with the drive shaft of the drive device 20.

[0056] like Figures 4 to 6 As shown, the first side surface 111 has a water-breaking area. Along the opposite direction of rotation of the wheel-shaped main body 13, the distance between at least two water-breaking areas gradually increases, forming a water-breaking part 1121 on the water-spraying surface 112 for breaking the liquid surface. In this way, the water-breaking part 1121 can further reduce the instantaneous shear force when the water-spraying protrusion 11 hits the liquid surface, thereby reducing the collision noise between the water-spraying structure 10 and the liquid surface when rotating at high speed and improving the user experience.

[0057] Specifically, the above-mentioned arrangement of the water-beating surface 112 actually makes the water-beating surface 112 present as the structure at the tip of the bottom of the boat, which greatly improves the water-breaking effect of the water-beating protrusion 11 and reduces the collision noise between the water-beating protrusion 11 and the liquid surface.

[0058] Specifically, an arc-shaped chamfer can be provided at the connection point of the two opposing first side surfaces 111 to further reduce the instantaneous shear force when the water-spraying protrusion 11 strikes the liquid surface.

[0059] like Figure 4 and Figure 5 As shown, the receiving portion 12 is a strip-shaped hole, which is arc-shaped and located on the side of the wheel-shaped main body 13. The protruding direction of the strip-shaped hole is opposite to the rotation direction of the water-spraying structure 10. Multiple receiving portions 12 are spaced apart around the rotation axis of the wheel-shaped main body 13. This perforated arrangement of the receiving portions 12 not only facilitates the flow of liquid into the receiving portions 12 after the water enters the water surface (i.e., water can flow through the receiving portions 12), thus initially increasing the amount of liquid carried by the receiving portions 12 during the rotation of the water-spraying structure 10, but also enables a lightweight design of the water-spraying structure 10. Simultaneously, because the protruding direction of the strip-shaped hole is opposite to the rotation direction of the water-spraying structure 10, the opening of the receiving portion 12 faces obliquely upward during water discharge, meaning the arc-shaped inner wall of the receiving portion 12 protrudes obliquely downward. This makes it easier for the receiving portion 12 to carry out water, further increasing the amount of liquid carried by the receiving portion 12 during the rotation of the water-spraying structure 10.

[0060] In this embodiment, there are 22 receiving portions 12 and 22 water-spraying protrusions 11.

[0061] It should be noted that the number of receiving sections 12 and water-spraying protrusions 11 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, there may be two, three, four, five, six, or more receiving sections 12. Optionally, there may be two, three, four, five, six, or more water-spraying protrusions 11.

[0062] like Figure 8 As shown, this embodiment also provides a portable air conditioner, which includes an air conditioner body 200 and a water-spraying device 100. The detection element 30 and the drive device 20 of the water-spraying device 100 are both connected to the control module of the air conditioner body 200. The control module controls at least one of the rotation speed or direction of the drive device 20 based on the detection value of the detection element 30; and / or controls the detection element 30 to be powered on or off based on the detection value of the detection element 30. The water-spraying structure 10 of the water-spraying device 100 is located within the water receiving tray 210 of the air conditioner body 200. The bottom wall of the water receiving tray 210 is an arc-shaped surface and has a confluence point. Along the direction from the outer circumference of the water receiving tray 210 to the confluence point, the height of the bottom wall of the water receiving tray 210 gradually decreases. The water-spraying device 100 is the aforementioned water-spraying device. In this way, the above-mentioned settings provide a control basis (control module) for the control process of the water pumping device 100. On the other hand, the bottom wall of the water receiving tray 210 can ensure that the condensate falling into the water receiving tray 210 can flow smoothly to the confluence point and be drained through the water pumping device 100, thereby preventing the condensate from accumulating in the water receiving tray 210 and breeding bacteria, thus improving the user experience.

[0063] In this embodiment, the confluence is also provided with a through hole, which is connected to the drain nozzle, allowing the user to operate the drain nozzle to open for manual drainage.

[0064] In this embodiment, the water receiving tray 210 is mounted on the chassis 240, and the water receiving tray 210 is also provided with a mounting bracket for mounting the evaporator 230, so that there is a certain gap between the evaporator 230 and the bottom wall of the water receiving tray 210, thereby ensuring that the condensate will not flow back into the evaporator 230 and extending the service life of the evaporator 230.

[0065] Specifically, the method for establishing the arc-shaped surface is as follows: A spatial rectangular coordinate system O-XYZ is established with the confluence point of the water receiving pan 210 as the origin. O-XY divides the bottom wall of the water receiving pan 210 into four planes. In each plane, the O-XZ plane or the O-YZ plane is used as the reference plane, and the lowest point (point O) is used as the reference point. Two drop points with a slope difference of 1° are arbitrarily created in the direction perpendicular to the reference plane (the angle between the line connecting the drop point and point O and the horizontal plane is the slope). Then, using any one of these two points as the reference point, a fourth point of the right angle side is created in the same way as above. Then, these four points are connected in pairs to create a curve. Finally, a curved surface (arc-shaped surface) is created by boundary blending. This curved surface is different from the traditional inclined plane. That is, the height difference between any point on this curved surface is the same as the height difference between the point on the circle with the distance between the two points as the radius in the X and Y directions with the origin O as the reference, so as to effectively ensure that the condensate on the bottom wall of the water receiving pan 210 flows quickly to the confluence point.

[0066] like Figure 8 As shown, the manifold is located below the condenser assembly of the air conditioner body 200. The condenser assembly includes at least two opposing condensers 220, which surround and form a receiving space 221. The water-spraying structure 10 of the water-spraying device 100 is located within the receiving space 221. In this way, the two condensers 220 can block the water splashed by the water-spraying structure 10, preventing water from splashing onto other electrical components (such as the evaporator 230) and affecting their normal operation, thereby improving the operational stability of the portable air conditioner. Simultaneously, due to the greater depth of the manifold, the size of the water-spraying structure 10 can also be set larger, further improving the water-spraying reliability of the water-spraying structure 10.

[0067] Specifically, since the confluence point is located below the condenser assembly and the water-spraying structure 10 of the water-spraying device 100 is located within the accommodating space 221, liquid that splashes onto the outer surface of the condenser 220 and does not evaporate in time can quickly flow back to the confluence point, thereby achieving rapid circulation water spraying by the water-spraying structure 10.

[0068] Specifically, the control module is the motherboard of the portable air conditioner.

[0069] like Figure 9 As shown, this embodiment also provides an air conditioner control method, applicable to the aforementioned portable air conditioner. The air conditioner control method includes:

[0070] Obtain the test value of the test piece 30 of the water dispensing device 100 of the portable air conditioner;

[0071] Determine the magnitude relationship between the detected value and the first preset value, the second preset value, and the third preset value;

[0072] If the detected value is less than or equal to the first preset value, the drive device 20 of the water pumping device 100 will stop running;

[0073] If the detected value is greater than the first preset value and less than or equal to the second preset value, the control drive device 20 drives the water-spraying structure 10 of the water-spraying device 100 to rotate.

[0074] If the detected value is greater than the third preset value, the control drive device 20 will stop running and the drainage indicator device of the portable air conditioner will start running.

[0075] Specifically, if the detected value is less than or equal to the first preset value, it means that the water-dispensing structure 10 is not in contact with the liquid surface. At this time, the control drive device 20 stops running, which can not only effectively prevent the water-dispensing structure 10 from idling and generating airflow noise, but also reduce the power consumption of the portable air conditioner, thereby improving the user experience. When the detected value is greater than the first preset value and less than or equal to the second preset value, it means that a certain amount of condensate is stored in the water tray 210 and the water-dispensing structure 10 is in contact with the liquid surface. At this time, driving the water-dispensing structure 10 to rotate ensures that the water-dispensing structure 10 can effectively dispense water and quickly drain the condensate on the water tray 210. When the detected value is greater than the third preset value, it means that the liquid level in the water tray 210 is too high. At this time, even if the water-dispensing structure 10 is driven to rotate, it cannot dispense water effectively. Therefore, the control drive device 20 stops running, and the control drain indicator device of the portable air conditioner is activated to prompt the user to perform manual draining operation.

[0076] Specifically, in this embodiment, the air conditioner control method is controlled by the motherboard (control module) of the portable air conditioner.

[0077] Specifically, the drainage indicator is a drainage indicator light on the portable air conditioner to remind the user to perform manual drainage.

[0078] Specifically, if the detected value is less than or equal to the first preset value, the control module determines that the portable air conditioner is in a "no water" state; if the detected value is greater than the first preset value and less than or equal to the second preset value, the control module determines that the portable air conditioner is in a "water" state; and if the detected value is greater than the third preset value, the control module determines that the portable air conditioner is in a "full water" state.

[0079] like Figure 4 and Figure 7 As shown, the method for determining the first preset value includes: obtaining the height value H1 of the lowest position of the water-spraying structure 10 relative to the bottom wall of the water receiving tray 210, and the first preset value is the height value H1.

[0080] like Figure 4 and Figure 7As shown, the method for determining the second preset value includes: forming an annular water-receiving area 14 between multiple receiving portions 12, obtaining the height value H2 of the lowest position of the inner contour line of the annular water-receiving area 14 relative to the bottom wall of the water receiving tray 210, the second preset value being the height value H2, and if it is greater than the height value, the liquid will submerge the receiving portion 12, and the water-spraying structure 10 will not be able to spray water effectively.

[0081] like Figure 4 and Figure 7 As shown, the method for determining the third preset value includes: obtaining the maximum detection height H3 of the detection component 30. The third preset value is greater than the second preset value and less than the maximum detection height H3, so as to avoid the detection component 30 from failing to detect or being damaged by water ingress.

[0082] like Figure 9 As shown, after the control drive device 20 stops operating and the control of the portable air conditioner's drainage indicator device starts operating, the air conditioner control method further includes:

[0083] The detection element 30 is powered on at a first preset time T1 to switch the detection element 30 to intermittent detection mode. The detection element 30 in intermittent detection mode detects the liquid level once at a first preset time T1.

[0084] If the detection value of the detection element 30 in the intermittent detection mode is less than or equal to the first preset value or the second preset value, the detection element 30 is controlled to continue to be powered on and the detection value of the detection element 30 is reacquired.

[0085] If the detection value of the detection element 30 in the intermittent detection mode is greater than the third preset value multiple times within the second preset time T2, then the portable air conditioner is controlled to switch to standby mode.

[0086] Since the portable air conditioner is in a "full water" state, the liquid level is close to the detection limit of the detection element 30. The detection element 30 is prone to water ingress and damage. Therefore, the detection element 30 is switched to intermittent detection mode to reduce the detection frequency of the "full water" detection element 30, reduce its damage probability, and thus improve the operational stability of the water dispensing device. This also avoids the detection element 30 being damaged, which would cause errors in its detection results and affect the accuracy of subsequent control.

[0087] Specifically, if the detection value of the detection element 30 in the intermittent detection mode is less than or equal to the first preset value or the second preset value, it means that the user has manually drained the water. At this time, the detection element 30 is restored to the continuous detection state (continuous power-on), and the detection value of the detection element 30 is obtained again to re-run the air conditioner control method.

[0088] Specifically, if the detection value of the detection element 30 in the intermittent detection mode is greater than the third preset value multiple times within the second preset time T2, it means that the user cannot manually drain the water temporarily. If the portable air conditioner continues to run, the condensate level may be too high, which may lead to water damage to other electrical components. At this time, switching the portable air conditioner to standby mode (that is, the internal electrical components and detection element 30 of the portable air conditioner are in a power-off state, and the user needs to turn it on again before it can be powered on and run) can ensure that the liquid in the portable air conditioner is manually drained before it continues to work, thereby extending the service life of the portable air conditioner.

[0089] In this embodiment, the air conditioner control method further includes:

[0090] After the detected value is less than or equal to the first preset value and the control drive device 20 stops running, the detected value of the detection element 30 is reacquired;

[0091] After the detected value is greater than the first preset value and less than or equal to the second preset value, and after the control drive device 20 drives the water spraying structure 10 to rotate for a third preset time T3, the detected value of the detection component 30 is reacquired.

[0092] In this way, when the portable air conditioner is in a "waterless" state, the control module can continuously acquire the detection value of the detection element 30 to obtain the condensate level in real time and make a quick response. After the water pumping structure 10 rotates for a third preset time T3 in the portable air conditioner in a "water-containing" state (after draining for a third preset time T3), the control module can reacquire the detection value of the detection element 30 to reacquire the condensate level in the portable air conditioner and re-execute the corresponding steps.

[0093] In this embodiment, the method for determining the magnitude relationship between the detected value and the third preset value includes: reacquiring at least two consecutive detected values ​​of the detection element 30; if both consecutive detected values ​​are greater than the third preset value, then the detected value is determined to be greater than the third preset value; if any consecutive detected value is less than or equal to the third preset value, then the detected value of the detection element 30 is reacquiring; and / or, the air conditioner control method further includes: if the detected value is greater than the second preset value and less than or equal to the third preset value, then the drive device 20 is controlled to stop operating.

[0094] In this way, the above settings can improve the accuracy of judging the relationship between the detected value and the third preset value, that is, avoid the instantaneous detection error of the detection element 30 caused by the sloshing of the liquid surface, and further improve the control accuracy of the air conditioner control method. On the other hand, if the detected value is greater than the second preset value and less than or equal to the third preset value, the water pumping structure 10 cannot effectively pump water and will make a lot of noise. Therefore, the control drive device 20 stops running to reduce the operating noise of the portable air conditioner.

[0095] Specifically, the operating time of the water-spraying structure 10 is controlled through the above control process, so that the operating time of the water-spraying structure 10 can match the overall operating status of the portable air conditioner, ensuring that the water-spraying structure 10 can effectively hit and splash condensate onto the fins of the condenser 220, thereby improving the heat exchange efficiency of the condenser 220.

[0096] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0097] A water-spraying device is installed inside the air conditioner body. The water-spraying structure of the water-spraying device is rotatably configured. The water-spraying structure has a water-spraying protrusion. The water-spraying protrusion is used to strike the liquid on the water receiving pan located in the air conditioner body onto the condenser of the air conditioner body during the rotation of the water-spraying structure. A drive device is driven and connected to the water-spraying structure to drive the water-spraying structure to rotate. A detection element is installed on the water receiving pan to detect the liquid level height value on the water receiving pan. The drive device's rotation speed or direction is controlled according to the detection value of the detection element; and / or, the detection element is powered on or off according to the detection value of the detection element. Thus, the portable air conditioner using the water-discharging device described in this application can, on the one hand, use the water-discharging structure to push the condensate on the drip tray onto the condenser, continuously and stably discharging the condensate from the drip tray to the air conditioner body through evaporation, thereby reducing the frequency of manual drainage by the user and initially improving the user experience; on the other hand, by controlling the detection element and the drive device for driving the water-discharging structure to rotate according to the detection value (liquid level), it can not only prevent the water-discharging structure from spinning idly when the water level is too low, causing it to emit large airflow noise, but also prevent the detection element from being damaged by water when the water level is too high, thereby reducing the operating noise of the portable air conditioner, improving the operational stability of the water-discharging device, further improving the user experience, and thus solving the problem that the drainage method of portable air conditioners in the prior art affects the user experience.
