Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a water pumping device, a portable air conditioner and an air conditioner control method. Background Art

[0002] At present, with the development of science and technology and the improvement of living standards, the traditional split air conditioner with the inner and outer units connected by copper tubes can no longer meet the users' outdoor use needs due to its difficult installation, huge size and immobility. Correspondingly, the new integrated portable air conditioner has been sought after by users due to its high comfort, multi-function and mobility.

[0003] In the prior art, since portable air conditioners need to be placed in corresponding usage scenarios (such as tents, desktops, etc.), their drainage design (mainly condensed water) has become a problem. The drainage methods that have been used can be roughly 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 shut down the machine and sound an alarm to remind the user to drain the water manually, thereby avoiding water damage to large electrical components caused by overflow of condensed water from the water tray.

[0005] Method 2: directly add a water pumping motor to the internal water receiving tray of the portable air conditioner, and use the water pumping motor to drive the water pumping wheel to rotate to disperse the evaporator condensate on the condenser fins for volatilization, so as to achieve uninterrupted discharge of the condensate.

[0006] However, the above drainage methods all have certain defects. For example, in method one, the user's manual drainage frequency is relatively high. During the user's rest period, it is very easy for the portable air conditioner to stop working and affect the user experience. For example, in method two, although the uninterrupted operation of the water wheel can ensure the continuous discharge of condensed water, its operation noise is relatively large, which also affects the user experience.

[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0042] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0043] In order to solve the problem in the prior art that the drainage method of a portable air conditioner may affect the user experience, the present 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 pumping device is arranged in the air conditioner body 200, and the water pumping device includes: a water pumping structure 10, which is rotatably arranged, and the water pumping structure 10 has a water pumping protrusion 11, and the water pumping protrusion 11 is used to pump 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 pumping structure 10; a driving device 20, which is connected to the water pumping structure 10 to drive the water pumping structure 10 to rotate; a detection member 30, which is arranged on the water receiving tray 210 to detect the liquid level 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 member 30; and / or, the detection member 30 is controlled to be powered on or off according to the detection value of the detection member 30.

[0045] Using the technical solution of this embodiment, a water pumping device is arranged in the air conditioner body 200, and a water pumping structure 10 of the water pumping device is rotatably arranged. The water pumping structure 10 has a water pumping protrusion 11. The water pumping protrusion 11 is used to pump 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 pumping structure 10. The driving device 20 is drivingly connected to the water pumping structure 10 to drive the water pumping structure 10 to rotate. The detection member 30 is arranged on the water receiving tray 210 to detect the liquid level 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 member 30; and / or, the detection member 30 is controlled to be powered on or off according to the detection value of the detection member 30. In this way, the portable air conditioner that uses the water pumping device in this embodiment for drainage can, on the one hand, use the water pumping structure 10 to pump the condensed water on the water receiving tray 210 onto the condenser 220, so as to continuously and stably discharge the condensed water on the water receiving tray 210 to the outside of the air conditioner main body 200 in the form of evaporation, thereby reducing the frequency of manual drainage by users and preliminarily improving the user experience; on the other hand, the detection member 30 and the driving device 20 for driving the water pumping structure 10 to rotate are controlled according to the detection value (liquid level) of the detection member 30, which can not only prevent the water pumping structure 10 from idling when the water level is too low and causing it to emit a large airflow noise; it can also prevent the detection member 30 from being flooded or damaged when the water level is too high, thereby reducing the operating noise of the portable air conditioner, improving the operating stability of the water pumping device, and further improving the user experience, thereby solving the problem in the prior art that the drainage method of the portable air conditioner will affect the user experience.

[0046] In this embodiment, the detection member 30 is a probe-type water level sensor having a probe 31 . The probe 31 can be inserted into the liquid to detect the liquid level.

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

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

[0049] Optionally, the driving device 20 is a servo motor.

[0050] Specifically, the detection member 30 may be disposed close to the water pumping structure 10 to ensure that the detection value of the detection member 30 is close to the liquid level value at the water pumping structure 10 to the greatest extent.

[0051] Specifically, the water splashed by the water-striking structure 10 will fall on the fins of the condenser 220, so that during the heat exchange process of the condenser 220, the liquid will evaporate through the condenser and flow out of the air conditioner body 200 with the internal air flow of the air conditioner body 200, thereby realizing the discharge of condensed water. At the same time, the condensed water with a lower temperature can also promote the heat exchange of the condenser 220, thereby improving the heat exchange efficiency of the condenser.

[0052] like Figure 4 and Figure 5 As shown, the water pumping structure 10 has a receiving portion 12 for receiving liquid, and the receiving portion 12 is arranged between the water pumping protrusion 11 and the rotation axis of the water pumping structure 10. In this way, the receiving portion 12 located between the water pumping protrusion 11 and the rotation axis of the water pumping structure 10 can allow the water supply liquid to flow into the receiving portion 12 after the water pumping protrusion 11 enters the water, and then during the rotation process of the water pumping structure 10, the water liquid is driven to splash, so as to form a water film on the outer surface of the water pumping structure 10, thereby improving the water pumping effect of the water pumping structure 10.

[0053] like Figures 4 to 6 As shown, the water-pumping structure 10 also has a wheel-shaped body 13, which is drivingly connected to the driving device 20, and a water-pumping protrusion 11 is arranged on the outer peripheral surface of the wheel-shaped body 13. The water-pumping protrusion 11 has at least two first side surfaces 111 arranged opposite to each other in the direction of the central axis of the wheel-shaped body 13, and the distance between the at least two first side surfaces 111 gradually increases along the direction from the water-pumping protrusion 11 to the central axis of the wheel-shaped body 13, so as to form a water-pumping surface 112 for striking the liquid surface. In this way, the above-mentioned arrangement of the water-pumping surface 112 can reduce the instantaneous shear force when the water-pumping protrusion 11 strikes the liquid surface, so as to reduce the disturbance of the water-pumping protrusion 11 to the water liquid, reduce the collision noise between the water-pumping structure 10 and the liquid surface when rotating at a high speed, and further improve the user experience.

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

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

[0056] like Figures 4 to 6 As shown, the first side surface 111 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 13, so as to form a water-breaking portion 1121 for breaking the liquid surface on the water-striking surface 112. In this way, the water-breaking portion 1121 can further reduce the instantaneous shear force when the water-striking protrusion 11 hits the liquid surface, thereby reducing the collision noise between the water-striking structure 10 and the liquid surface when rotating at a high speed, and improving the user experience.

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

[0058] Specifically, an arc-shaped chamfer may be provided at the connection between two first side surfaces 111 arranged opposite to each other, so as to further reduce the instantaneous shear force when the water-striking protrusion 11 strikes the liquid surface.

[0059] like Figure 4 and Figure 5 As shown, the receiving portion 12 is a strip hole, which is arranged in an arc shape, and is arranged on the side of the wheel-shaped body 13. The protruding direction of the strip hole is opposite to the rotation direction of the water-pumping structure 10. There are multiple receiving portions 12, and the multiple receiving portions 12 are arranged at intervals around the rotation axis of the wheel-shaped body 13. In this way, the hole-shaped receiving portion 12 is not only conducive to promoting the liquid to flow into the receiving portion 12 after it enters the water surface (that is, the water can flow through the receiving portion 12), thereby preliminarily increasing the amount of liquid brought up by the receiving portion 12 during the rotation of the water-pumping structure 10, but also can achieve a lightweight design of the water-pumping structure 10. At the same time, since the protruding direction of the strip hole is opposite to the rotation direction of the water-pumping structure 10, the opening direction of the receiving portion 12 during the water discharge process is inclined upward, that is, the arc-shaped inner wall of the receiving portion 12 protrudes toward the oblique downward, so that the receiving portion 12 is easier to bring out the water, and the amount of liquid brought up by the receiving portion 12 during the rotation of the water-pumping structure 10 is further increased.

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

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

[0062] like Figure 8 As shown, this embodiment also provides a portable air conditioner, which includes an air conditioner body 200 and a water pumping device 100. The detection member 30 and the driving device 20 of the water pumping 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 the direction of the driving device 20 according to the detection value of the detection member 30; and / or controls the detection member 30 to be powered on or off according to the detection value of the detection member 30; the water pumping structure 10 of the water pumping device 100 is located in the water receiving tray 210 of the air conditioner body 200, the bottom wall of the water receiving tray 210 is an arc surface and has a confluence, and the height of the bottom wall of the water receiving tray 210 gradually decreases along the outer peripheral surface of the water receiving tray 210 to the confluence. Among them, the water pumping device 100 is the above-mentioned water pumping device. In this way, on the one hand, the above-mentioned setting provides a control basis (control module) for the control process of the water pumping device 100; on the other hand, the bottom wall setting of the water receiving tray 210 can ensure that the condensed water falling onto the water receiving tray 210 can flow smoothly to the confluence and be drained through the water pumping device 100, thereby preventing the condensed water from accumulating in the water receiving tray 210 and breeding bacteria, thereby improving the user experience.

[0063] In this embodiment, a through hole is also provided at the confluence, and the through hole is connected to the drainage nozzle. The user can operate the drainage nozzle to open it to realize manual drainage operation.

[0064] In this embodiment, the water receiving tray 210 is arranged on the base tray 240, and a mounting bracket is also provided on the water receiving tray 210. The mounting bracket is used to install 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 condensed water does not flow back into the evaporator 230, thereby extending the service life of the evaporator 230.

[0065] Specifically, the method for establishing the arc surface is as follows: a spatial rectangular coordinate system O-XYZ is established with the confluence of the water receiving tray 210 as the origin, O-XY divides the bottom wall of the water receiving tray 210 into four planes, and 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, and 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), and then any one of the two points is used as the reference point to create the fourth point of the right-angle side in the above manner, and then the four points are connected in pairs to create a curve, and finally a curved surface (arc surface) is created by boundary blending. This curved surface is different from a 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 origin O as the reference and the distance between the above two points as the radius in the X and Y directions to the origin O, thereby effectively ensuring that the condensed water on the bottom wall of the water receiving tray 210 flows quickly to the confluence.

[0066] like Figure 8 As shown, the confluence is located below the condenser assembly of the air conditioner body 200, and the condenser assembly includes at least two condensers 220 arranged opposite to each other, and at least two condensers 220 arranged opposite to each other surround and form a receiving space 221. Among them, the water pumping structure 10 of the water pumping device 100 is located in the receiving space 221. In this way, the two condensers 220 can block the water liquid hit and splashed by the water pumping structure 10 to prevent the water liquid from splashing onto other electrical components (such as the evaporator 230) and affecting the normal operation of other electrical components, thereby improving the operating stability of the portable air conditioner. At the same time, due to the large depth of the confluence, the size of the water pumping structure 10 can also be set larger, further improving the reliability of the water pumping structure 10.

[0067] Specifically, since the confluence is located below the condenser assembly and the water pumping structure 10 of the water pumping device 100 is located in the accommodating space 221, the liquid that has splashed onto the outer surface of the condenser 220 and has not evaporated in time can quickly flow back to the confluence, thereby realizing rapid circulation water pumping of the water pumping structure 10.

[0068] Specifically, the control module is a main board of the portable air conditioner.

[0069] like Fig. 9 As shown, this embodiment also provides an air conditioner control method, which is applicable to the above-mentioned portable air conditioner. The air conditioner control method includes:

[0070] Acquire the detection value of the detection component 30 of the water pumping device 100 of the portable air conditioner;

[0071] Determine the magnitude relationship between the detection 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 driving device 20 of the water pumping device 100 is controlled to 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 driving device 20 is controlled to drive the water pumping structure 10 of the water pumping device 100 to rotate;

[0074] If the detected value is greater than the third preset value, the driving device 20 is controlled to stop running and the drainage prompting device of the portable air conditioner is controlled to run.

[0075] Specifically, if the detection value is less than or equal to the first preset value, it means that the water pumping structure 10 is not in contact with the liquid surface. At this time, the driving device 20 is controlled to stop running, which can not only effectively avoid the water pumping structure 10 from idling and emitting airflow noise, but also reduce the power consumption of the portable air conditioner, thereby improving the user experience. When the detection 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 condensed water is stored in the water receiving tray 210 and the water pumping structure 10 is in contact with the liquid surface. At this time, the water pumping structure 10 is driven to rotate, which ensures that the water pumping structure 10 can effectively pump water and discharge the condensed water on the water receiving tray 210 as soon as possible; and when the detection value is greater than the third preset value, it means that the liquid level in the water receiving tray 210 is too high. At this time, even if the water pumping structure 10 is driven to rotate, it is impossible to effectively pump water. Therefore, the driving device 20 is controlled to stop running, and the drainage prompt device of the portable air conditioner is controlled to run to prompt the user to perform manual drainage operation.

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

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

[0078] Specifically, if the detection 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 detection 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; if the detection 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 a height value H1 of the lowest position of the water pumping 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-collecting area 14 between multiple accommodating portions 12, obtaining a height value H2 of the lowest position of the inner circle contour line of the annular water-collecting area 14 relative to the bottom wall of the water receiving tray 210, and the second preset value is the height value H2, and if it is greater than the height value, the liquid will submerge the accommodating portion 12, and the water-pumping structure 10 cannot effectively pump water.

[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 member 30, the third preset value is greater than the second preset value and less than the maximum detection height H3, so as to avoid detection failure and water damage to the detection member 30.

[0082] like Fig. 9 As shown, after the driving device 20 is controlled to stop running and the drainage prompting device of the portable air conditioner is controlled to run, the air conditioner control method further includes:

[0083] Controlling the detection member 30 to be powered on at intervals of a first preset time T1, so as to switch the detection member 30 to an intermittent detection mode, and the detection member 30 in the intermittent detection mode detects the liquid level once at intervals of the 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 be continuously powered on, and the detection value of the detection element 30 is re-acquired;

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

[0086] In this way, since the portable air conditioner is in a "full water" state, the liquid level is close to the detection limit of the detection component 30, and the detection component 30 is easily damaged by water. Therefore, the detection component 30 is switched to the intermittent detection mode to reduce the detection frequency of the "full water" detection component 30 and reduce its damage probability, thereby improving the operating stability of the water pumping device and avoiding damage to the detection component 30, which may cause errors in its detection results, thereby affecting the subsequent control accuracy.

[0087] Specifically, if the detection value of the detection component 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 performed manual drainage. At this time, the detection component 30 is restored to the continuous detection state (continuously powered on), and the detection value of the detection component 30 is re-obtained to re-run the air conditioner control method.

[0088] Specifically, if the detection values ​​of the detection component 30 in the intermittent detection mode within the second preset time T2 are all greater than the third preset value, it means that the user is temporarily unable to manually drain the water. That is, if the portable air conditioner continues to run, it may cause the condensation water level to be too high, and then cause other electrical components to be damaged by water. At this time, switching the portable air conditioner to standby mode (that is, the electrical components and the detection component 30 inside the portable air conditioner are all in a power-off state, and the user needs to restart the machine before it can be powered on and run again) can ensure to the greatest extent 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] When the detection value is less than or equal to the first preset value and the driving device 20 is controlled to stop running, the detection value of the detection member 30 is acquired again;

[0091] When the detection value is greater than the first preset value and less than or equal to the second preset value, and the driving device 20 is controlled to drive the water pumping structure 10 to rotate for a third preset time T3, the detection value of the detection member 30 is acquired again.

[0092] In this way, when the portable air conditioner is in the "water-free" state, the control module can continuously obtain the detection value of the detection component 30 to obtain the condensed water level in real time and respond quickly. After the water-pumping structure 10 rotates for the third preset time T3 in the portable air conditioner in the "water" state (after the third preset time T3 of drainage), the control module can re-obtain the detection value of the detection component 30 to re-obtain the condensed water 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 detection value and the third preset value includes: reacquiring at least two consecutive detection values ​​of the detection element 30; if at least two consecutive detection values ​​are greater than the third preset value, determining that the detection value is greater than the third preset value; if any one consecutive detection value is less than or equal to the third preset value, reacquiring the detection value of the detection element 30; and / or, the air conditioner control method also includes: if the detection value is greater than the second preset value and less than or equal to the third preset value, controlling the drive device 20 to stop running.

[0094] In this way, on the one hand, the above-mentioned setting can improve the accuracy of judging the size relationship between the detection value and the third preset value, that is, avoid the shaking of the liquid surface and cause the detection member 30 to have an instantaneous detection error, and further improve the control accuracy of the air conditioner control method; on the other hand, if the detection 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 at this time, and will emit a loud noise, so the control drive device 20 is stopped to reduce the operating noise of the portable air conditioner.

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

[0096] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0097] A water pumping device is arranged in the air conditioner body, and a water pumping structure of the water pumping device is rotatably arranged. The water pumping structure has a water pumping protrusion, and the water pumping protrusion is used to pump 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 pumping structure. The driving device is connected to the water pumping structure to drive the water pumping structure to rotate. The detection element is arranged on the water receiving tray to detect the liquid level height value on the water receiving tray, so as to control at least one of the rotation speed or direction of the driving device according to the detection value of the detection element; and / or, the detection element is controlled to be powered on or off according to the detection value of the detection element. In this way, the portable air conditioner that uses the water-pumping device in the present application for drainage, on the one hand, can use the water-pumping structure to blow the condensed water on the water receiving tray onto the condenser, so as to continuously and stably discharge the condensed water on the water receiving tray to the outside of the air conditioner body through evaporation, thereby reducing the frequency of manual drainage by users and preliminarily improving the user experience; on the other hand, the detection member and the driving device for driving the water-pumping structure to rotate are controlled according to the detection value (liquid level) of the detection member, which can not only prevent the water-pumping structure from idling when the water level is too low and causing it to emit a large airflow noise; it can also prevent the detection member from being flooded or damaged when the water level is too high, thereby reducing the operating noise of the portable air conditioner, improving the operating stability of the water-pumping device, and further improving the user experience, thereby solving the problem in the prior art that the drainage method of the portable air conditioner will affect the user experience.
