Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioners, and particularly relates to a water spraying device and an air conditioner. Background Art

[0002] During the operation of an air conditioner, since the surface temperature of the evaporator is lower than the dew point temperature of the air, moisture in the air will condense and precipitate on the surface of the evaporator to form condensed water. Currently, in an integral air conditioner, the condensed water generated by the evaporator is often collected in a water receiving tray below the condenser. The water spraying impeller in the water receiving tray rotates at high speed under the drive of a motor to disperse the condensed water by striking, and the condensed water is splashed onto the condenser. The evaporation heat absorption of water is used to cool the condenser, thereby improving the heat dissipation efficiency of the condenser, and further obtaining higher cooling capacity and energy efficiency ratio. In a mobile air conditioner, a water storage tank is generally provided on the parts at the lower end of the condenser, and the condensed water generated during the heat exchange of the evaporator is introduced into the water storage tank. At the same time, a certain gap is reserved among multiple fins of the condenser, and a water spraying flywheel is placed in this gap. The motor drives the water spraying flywheel to disperse the condensed water in the water storage tank, making it splash onto the condenser fins to achieve the purpose of cooling the condenser. For a window air conditioner, water spraying ribs are generally designed on the outer ring of the axial flow fan blade. By using the high-speed rotation of the axial flow fan blade, the water spraying ribs strike the condensed water, making the condensed water splash onto the condenser and evaporate, thereby strengthening the heat exchange. No matter which of the above structural forms, the position of the water spraying device is fixed, and the best water spraying effect can only be obtained at a certain specific water level height. When the water level is relatively shallow, water cannot be sprayed; when the water level is relatively high, the water is sprayed too fast and cannot be dispersed; when the water level is too high, the resistance of the water spraying flywheel is even too large to drive the water. Summary of the Invention

[0003] Therefore, the present invention provides a water spraying device, which can solve the problem that the position of the water spraying device used in the air conditioner is fixed and cannot be adjusted according to the height of the water level, resulting in poor water spraying effect in many cases.

[0004] To solve the above problems, the present invention provides a water spraying device, including: a floating component and a water spraying assembly. The water spraying assembly includes a driving component and a water spraying impeller. The floating component has opposite first and second end faces. The driving component is arranged on the first end face, and the driving component is drivingly connected to the water spraying impeller. The driving component is used to drive the water spraying impeller to rotate. The water spraying impeller is located outside the floating component, and the floating component can drive the water spraying assembly to rise and fall by the buoyancy of the second end face.

[0005] In some embodiments, the water spraying device further includes a vertically arranged guiding component. The floating component is sleeved outside the guiding component, and the floating component can move along the height direction of the guiding component under the action of the buoyancy of the second end face.

[0006] In some embodiments, the floating member is made of foam, a fixing member is provided on the first end face, and the driving member is provided on the fixing member.

[0007] In some embodiments, the number of the guiding members is two, and the two guiding members are respectively located on both sides of the fixing member.

[0008] In some embodiments, a sliding groove is formed on the guiding member, the fixing member has a sliding fit portion, and the sliding fit portion is slidably limited in the sliding groove.

[0009] In some embodiments, a limiting structure is provided at the top of the guiding member, and the limiting structure is used to limit the movement of the fixing member in the height direction of the guiding member.

[0010] In some embodiments, a water level monitoring mechanism is further included, and the water level monitoring mechanism is used to monitor the water level in the water receiving tray where the water pumping device is located.

[0011] In some embodiments, the water level monitoring mechanism includes a magnetic member and a sensing member, the magnetic member is provided on the fixing member, and the sensing member is provided on the limiting structure.

[0012] In some embodiments, in the direction from the first end face to the second end face, the cross-sectional area of the floating member gradually increases.

[0013] The present invention also provides an air conditioner, including the above-mentioned water pumping device.

[0014] The present invention provides a water pumping device and an air conditioner. When the water pumping device of the present application is applied in the water receiving tray of the air conditioner, since the weights of the floating member, the driving member, and the water pumping impeller are constant, if the water level in the water receiving tray changes, under the buoyancy of the water, the floating member will also drive the driving member and the water pumping impeller to synchronously rise or fall following the change of the water level. That is, the water intake depth of the water pumping impeller remains unchanged all the time, realizing that within a certain water level height range, the water pumping effect is scattered, uniform, and continuous, and making the water pumping effect in the best state in most cases, thereby improving the heat exchange efficiency of the condenser and the energy efficiency ratio.

[0022] Referring to Figures 1 to 5 As shown, according to an embodiment of the present invention, a water pumping device is provided, including: a floating member 1 and a water pumping assembly. The water pumping assembly includes a driving member 2 and a water pumping impeller 3. The floating member 1 has opposite first and second end faces. The driving member 2 is disposed on the first end face. The driving member 2 is drivingly connected to the water pumping impeller 3. The driving member 2 is configured to drive the water pumping impeller 3 to rotate. The water pumping impeller 3 is located outside the floating member 1. The floating member 1 can drive the water pumping assembly to rise and fall by the buoyancy of the second end face. In this technical solution, when the water pumping device of the present application is applied in the water receiving tray 10 of an air conditioner, since the weights of the floating member 1, the driving member 2 and the water pumping impeller 3 are constant, if the water level in the water receiving tray 10 changes, under the action of the buoyancy of the water, the floating member 1 will also drive the driving member 2 and the water pumping impeller 3 to rise or fall synchronously with the change of the water level. That is, the water intake depth of the water pumping impeller 3 remains unchanged all the time, realizing that within a certain water level height range, the water pumping effect is dispersed, uniform and continuous, and making the water pumping effect in an optimal state in most cases, thereby improving the heat exchange efficiency of the condenser and the energy efficiency ratio. The floating member 1 can be made of a material with a density less than that of water, or can be made of a material with a density greater than that of water. When the floating member 1 is made of a material with a density greater than that of water, it can be made into a hollow structure to ensure that it can float on the water surface.

[0023] As a specific implementation manner, a through hole is formed in the floating member 1, and the water pumping device further includes a guiding member 4 vertically arranged. The guiding member 4 passes through the through hole of the floating member 1 and is fixed in the water receiving tray 10. The guiding member 4 plays a role in limiting and guiding the floating member 1, ensuring that when the floating member 1 rises or falls synchronously following the change of the water level, its position in the horizontal direction will not change too much. Furthermore, it ensures that the position of the water pumping impeller 3 in the horizontal direction will not change too much, guaranteeing the accuracy of the relative position between the water pumping impeller 3 and the condenser assembly 11. In a specific embodiment, the guiding member 4 is specifically a straight rod or a straight strip.

[0024] Preferably, the floating member 1 is made of foam, and the driving member 2 is a motor. Since the foam material is relatively soft and it is not suitable to directly fix the driving member 2 thereon, a fixing member 5 needs to be arranged on the floating member 1, and it is more appropriate to install the driving member 2 on the fixing member 5.

[0025] Referring to Figure 4 As shown, the number of the guiding members 4 is two, and the two guiding members 4 are respectively located on both sides of the fixing member 5. Since the floating member 1 moves along the height direction of the guiding member 4 under the buoyancy of water, there is a gap between the outer surface of the guiding member 4 and the through hole of the floating member 1. When the two guiding members 4 are respectively located on both sides of the fixing member 5, the two guiding members 4 also form a limit for the fixing member 5 in the horizontal direction, which can further ensure that the position of the floating member 1 in the horizontal direction will not change too much, and further ensure that the position of the water pumping impeller 3 in the horizontal direction will not change too much.

[0026] Referring to Figure 3 and Figure 4 As shown, a sliding groove 6 is formed in the guiding member 4, and the fixing member 5 has a sliding fit portion, and the sliding fit portion is slidably limited in the sliding groove 6. This can further ensure that the position of the floating member 1 in the horizontal direction will not change too much, and further ensure that the position of the water pumping impeller 3 in the horizontal direction will not change too much.

[0027] In a specific embodiment, a limiting structure 7 is arranged at the top of one of the guiding members 4. The limiting structure 7 is a baffle, which extends from the top of one of the guiding members 4 towards the direction where the other guiding member 4 is located, thereby forming a block for the fixing member 5 to have an upper limit and preventing the floating member 1 from driving the fixing member 5 and the water pumping assembly to float out of the track.

[0028] In this embodiment, the water pumping device further includes a water level monitoring mechanism for monitoring the water level height in the water receiving tray 10. When the water level in the water receiving tray 10 is relatively high, the water level monitoring mechanism will feedback to the control device of the air conditioner, and then the control device controls the driving component 2 to increase the rotation speed, accelerate the water pumping efficiency, and speed up the consumption speed of the condensed water; or the control device controls the compressor to temporarily stop working, so that the evaporator no longer generates condensed water, so as to prevent the water level in the water receiving tray 10 from overflowing too high and affecting the user experience. When the water pumping impeller 3 consumes the condensed water in the water receiving tray 10 to an appropriate water level height, the compressor is then controlled to continue working.

[0029] Referring to Figure 1 As shown, the water level monitoring mechanism includes a magnetic member 8 and a sensing member 9. The magnetic member 8 is arranged on the fixed member 5, and the sensing member 9 is arranged on the limiting structure 7. When the floating member 1 drives the fixed member 5 to rise under the buoyancy of water, the sensing member 9 will detect a change in the magnetic field intensity, thereby detecting that the water level reaches the high water level.

[0030] In a specific embodiment, in the direction from the first end face to the second end face, the cross-sectional area of the floating member 1 gradually increases. At the preset draft depth, the water entry angle of the water pumping impeller 3 is the same, the water pumping resistance is the same, and the dispersion effect of the splashed water is also basically the same. Obviously, the draft depth of the water pumping impeller 3 is related to the drainage volume of the floating member 1. The lower part of the floating member 1 is mainly for drainage, and the buoyancy of the floating member 1 can be adjusted by adjusting the size of the lower cross-sectional area of the floating member 1. When the floating member 1 is designed with a larger bottom and a smaller top structure, it can obtain greater buoyancy, so that the water pumping impeller 3 obtains the optimal draft depth, thereby strengthening the water pumping and cooling of the condenser and improving the refrigerating capacity and energy efficiency ratio of the air conditioner.

[0031] According to an embodiment of the present invention, an air conditioner is further provided, including the above-mentioned water pumping device.

[0032] It is easy for those skilled in the art to understand that, on the premise of no conflict, the above-mentioned advantageous ways can be freely combined and superimposed.

Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
