DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The present application is further described in detail below in conjunction with the accompanying drawings.

[0021] The present application provides a mobile air-conditioning water pumping structure, such as Figure 1 and Figure 2 As shown, the mobile air conditioner water pumping structure includes: a motor 100 and a water pumping wheel 200 sleeved on the rotating shaft 110 of the motor 100. The water pumping wheel 200 includes a first wheel 210, a second wheel 220 and spokes 230, wherein the first wheel 210 is arranged at the center of the water pumping wheel 200 and sleeved on the rotating shaft 110 of the motor 100; the second wheel 220 is arranged around the outer side of the first wheel 210, and the second wheel 220 is connected to the first wheel 210 through a plurality of spokes 230, and the spokes 230 are extended and arranged corresponding to the involute of the first wheel 210 to form the water pumping structure of the water pumping wheel 200. By arranging spokes 230 extending along the involute direction of the first wheel 210 between the first wheel 210 and the second wheel 220, and utilizing the spokes 230 as a water-pumping structure, the accumulated water is lifted to both sides of the water-pumping wheel, thereby making it possible to utilize the evaporators on both sides of the water-pumping wheel with maximum efficiency, and ensuring the water-pumping effect without increasing the lift of the accumulated water. This ensures the water-pumping efficiency of the overall mobile air-conditioning water-pumping structure without changing the overall water-pumping wheel size and without increasing the motor power, thereby achieving a low-noise, low-power, and efficient water-pumping function.

[0022] Furthermore, 20-30 spokes 230 are evenly spaced between the first wheel 210 and the second wheel 220. The spokes 230 are evenly arranged between the first wheel 210 and the second wheel 220, thereby further improving the pumping efficiency of the entire water wheel and avoiding noise during the pumping process.

[0023] Furthermore, if Figure 6 and Figure 7As shown, the spoke 230 includes a water-hitting surface 231 and a water-receiving surface 232, wherein Figure 7 As shown, the water-pumping surface 231 includes a first water-pumping surface 2311 and a second water-pumping surface 2312 which are symmetrical with respect to the axial section of the water-pumping wheel 200, and the back water surface 232 includes a first back water surface 2321 and a second back water surface 2322 which are symmetrical with respect to the axial section of the water-pumping wheel 200, and the angles between the first water-pumping surface 2311, the second water-pumping surface 2312, the first back water surface 2321 and the second back water surface 2322 and the axial section of the water-pumping wheel 200 are greater than 90°, so as to lift the accumulated water to the two sides of the water-pumping wheel 200, thereby maximizing the utilization of the evaporators on both sides of the water-pumping wheel 200 and ensuring the evaporation efficiency of the evaporator on the lifted water mist without increasing the head of the accumulated water.

[0024] Furthermore, if Figure 3 and Figure 5 As shown, the first wheel 210 includes a body 211, an outer ring 212 and a connecting portion 213. The outer ring 212 is arranged around the body 211, and one end of the spoke 230 is fixed on the outside of the outer ring 212. The axial width of the outer ring 212 is greater than the axial width of the body 211. The connecting portion 213 is vertically arranged at the center of the body 211 and corresponds to the rotating shaft 110 of the motor 100 to achieve the sleeve connection between the first wheel 210 and the motor 100. The axial width of the body 211 is set to be smaller, while ensuring that the outer ring 212 has a larger axial width to ensure the connection stability between the outer ring 212 and the spoke 230, thereby reducing the weight of the overall water wheel while ensuring the water pumping efficiency, reducing the power required by the motor, and reducing noise.

[0025] Furthermore, the axial width of the second wheel 220 is equal to the axial width of the outer ring 212 of the first wheel 210. The two ends of the spokes 230 are respectively fixed on the outer rings 212 of the second wheel 220 and the first wheel 210, and the width of the spokes 230 is kept uniform, thereby ensuring the water pumping efficiency of the entire water wheel and avoiding noise due to vibration. Furthermore, the inner side of the second wheel 220 is provided with a first surface 221 and a second surface 222 symmetrical with respect to the axial section of the water wheel 200, and the angle between the first surface 221 and the second surface 222 and the axial section of the water wheel 200 is greater than 90°, so as to cooperate with the spokes 230 to lift the accumulated water to the two sides of the water wheel 200, thereby maximizing the use of the evaporators on both sides of the water wheel 200, and ensuring the evaporation efficiency of the evaporators on the lifted water mist without increasing the head of the accumulated water.

[0026] Furthermore, if Figure 3 and Figure 5 As shown, a through holding space 214 is formed in the interior of the connecting portion 213 along the axial direction, and the holding space 214 is matched with the top end 111 of the rotating shaft 110 of the motor 100, so as to realize the sleeve of the first wheel 210 on the rotating shaft 110 of the motor 100. By using the holding space 214 matching the rotating shaft 110, the detachable connection between the water wheel 200 and the motor 100 can be realized, and the loading and unloading operation is simple and fast.

[0027] Furthermore, if Figure 5 and Figure 8 As shown, the top end 111 of the rotating shaft 110 is a semi-cylindrical setting, and the clamping space 214 inside the connecting portion 213 is a corresponding semi-cylindrical through hole. The design of the semi-cylindrical body and the corresponding semi-cylindrical through hole ensures that the clamping space 214 corresponds to the top end 111 of the rotating shaft 110, making the positioning and installation easier, and ensuring that the water wheel 200 rotates synchronously with the rotating shaft 110 of the motor 100 after the assembly is completed.

[0028] Furthermore, if Figure 3 and Figure 8 As shown, the motor 100 further includes a fixing screw 120, and the top 111 of the rotating shaft 110 is provided with a thread 112. After the connecting portion 213 is sleeved on the top 111 of the rotating shaft 110, the water wheel 200 is fixed to the rotating shaft 110 through the cooperation of the fixing screw 120 and the thread 112. The cooperation of the fixing screw 120 and the thread 112 further enhances the connection stability between the water wheel 200 and the rotating shaft 110, thereby avoiding loss and reducing noise during operation.

[0029] Furthermore, if Figure 3 and Figure 5 As shown, the body 211 is provided with a plurality of through holes 215 along the axial direction to reduce the weight of the water wheel 200. By providing evenly distributed through holes 215 on the body 211, the weight of the water wheel 200 is reduced, and the power required by the motor 100 is further reduced while ensuring the water pumping efficiency.

[0030] Furthermore, if Figure 5 As shown, the motor 100 further includes a fixing structure 130, which is arranged around the motor 100 to fix the mobile air conditioner water pumping structure in the mobile air conditioner. By pre-arranging the fixing structure 130, the mobile air conditioner water pumping structure can be quickly installed in the mobile air conditioner, which is convenient for replacement.

[0031] The present application arranges spokes extending along the involute direction of the first wheel between the first wheel and the second wheel, utilizes the spokes as a water-pumping structure, and combines the structural design of other water-pumping wheels and a motor, thereby ensuring the water-pumping efficiency of the overall mobile air-conditioning water-pumping structure without changing the overall water-pumping wheel size and without increasing the motor power, thereby achieving a low-noise, low-power and efficient water-pumping function.

[0032] Furthermore, the embodiments of the present application also disclose a mobile air conditioner drainage-free structure. Fig. 9 As shown, it includes a chassis 300 of a mobile air conditioner and a water pumping structure of the mobile air conditioner fixed on the chassis 300, wherein the water pumping structure of the mobile air conditioner includes a motor 100 and a water pumping wheel 200, and the water pumping wheel 200 is sleeved on the rotating shaft 110 of the motor 100 and arranged above the chassis 300, so that when the motor 100 starts to work, the water pumping wheel 200 rotates synchronously with the rotating shaft 110, and the condensed water deposited in the chassis 300 is lifted to both sides and evaporated again, thereby realizing the function of no drainage. Further, as Fig.10 As shown, the drainage-free structure of the mobile air conditioner also includes an evaporator 400 vertically arranged above the water-pumping structure of the mobile air conditioner, and the evaporator 400 clamps the water-pumping wheel 200 in the middle position, that is, the evaporator 400 is respectively arranged on both sides of the water-pumping wheel 200, so that when the motor 100 starts to work, the water-pumping wheel 200 rotates synchronously with the rotating shaft 110, and the condensed water deposited in the chassis 300 is lifted to both sides, and secondary evaporation is performed on the evaporators on both sides to realize the drainage-free function, thereby reducing the drainage required for the mobile air conditioner, and can maximize the evaporation effect of the evaporator without increasing the water head. At the same time, the use steps are simplified to provide users with a more convenient use experience.

[0033] Furthermore, in the mobile air conditioner water pumping structure described in this embodiment, the water pumping wheel 200 includes a first wheel 210 , a second wheel 220 and a plurality of spokes 230 .

[0034] Specifically, if Figure 3 and Figure 5 As shown, the first wheel 210 is arranged at the center of the water wheel 200, and is arranged in a round pancake shape as a whole. Specifically, the first wheel 210 includes a body 211, an outer ring 212 and a connecting portion 213, wherein the body 211 is in a round pancake shape and is arranged coaxially with the rotating shaft 110, so that after the water wheel 200 is sleeved on the rotating shaft 110, the water wheel 200 can rotate evenly with the rotating shaft 110. Optionally, a plurality of through holes 215 are symmetrically arranged on the body 211 to reduce the weight of the body 211, thereby reducing the power required to be output by the motor 100, saving energy and protecting the environment, and reducing noise.

[0035] Furthermore, if Figure 3 and Figure 4 As shown, the outer ring 212 is arranged around the edge of the body 211, and one end of the spoke is fixedly arranged on the outside of the outer ring 212. The outer ring 212 is arranged along the edge of the body 211 and extends perpendicularly to the body 211, so that the axial width of the outer ring 212 is greater than the axial width of the body 211, and the weight of the first wheel 210 is further reduced on the basis of ensuring the stable connection between the outer ring 212 and the spoke 230, and the required water pumping effect can still be provided when the motor 100 outputs a lower power, thereby reducing the noise during operation.

[0036] Furthermore, if Figure 5 As shown, the connecting portion 213 is arranged at the center of the body 211 and is arranged perpendicular to the body 211 to correspond to the rotating shaft 110 of the motor 100. Specifically, the connecting portion 213 is a hollow cylindrical structure, and a through holding space 214 is arranged inside along the axial direction. The holding space 214 is matched with the rotating shaft 110, so that the rotating shaft 110 is held by the holding space 214, and the connecting portion 213 is sleeved on the rotating shaft 110 by passing the rotating shaft 110 through the holding space 214, so that the water wheel 200 is sleeved on the rotating shaft 110. Specifically, the holding space 214 is an asymmetric structure to ensure the positioning direction when the water wheel 200 is sleeved on the rotating shaft 110, reducing the difficulty of installation. Optionally, the holding space 214 is a semi-cylindrical through hole passing through the main body 211 to match the rotating shaft 110 set in the semi-cylinder, so that the user can more easily install the water wheel 200 on the rotating shaft 110 of the motor 100, and when the motor 100 starts to work, there will be no relative rotation between the rotating shaft 110 and the connecting part 213, so the water wheel 200 can rotate synchronously with the rotating shaft 110 to achieve the water pumping function.

[0037] Furthermore, if Figure 4 and Figure 5As shown, one end of the spoke 230 is fixed to the outside of the outer ring 212. Specifically, a plurality of spokes 230 are evenly arranged around the outside of the outer ring 212 at the same interval, and all the spokes 230 are extended along the involute direction of the first wheel 210. In other words, the contour of the outer ring 212 of the first wheel 210 forms the involute of the spoke 230. Specifically, the first wheel 210 is a circular structure, and the spokes 230 intersect with all tangents of the first wheel 210 at right angles, so that the shape of the spokes 230 can minimize noise while maximizing the pumping efficiency. Further, 20-30 spokes 230 are evenly arranged on the outer ring 212 of the first wheel 210, and each of the spokes 230 is extended corresponding to an involute of the first wheel 210. Preferably, 25 spokes 230 are evenly arranged on the outer ring 212 of the first wheel 210, and each spoke 230 is extended and arranged corresponding to an involute of the first wheel 210, so as to ensure the pumping efficiency of the water wheel 200 and reduce the noise during the pumping process. Optionally, the diameter of the first wheel 210 is 36-44 mm, and the spokes 230 are extended and arranged along the involute direction of a concentric circle with a diameter greater than that of the first wheel 210. For example, the diameter of the first wheel 210 is 40 mm, and the spokes 230 are extended and arranged along the involute direction of a circle with a diameter of 44 mm and concentric with the first wheel 210, so as to ensure the pumping efficiency of the water wheel 200 and reduce the noise during the pumping process.

[0038] Furthermore, if Figure 6 and Figure 7 As shown, the spoke 230 includes a water-spraying surface 231 and a water-receiving surface 232, wherein the axis of the spoke 230 is extended to correspond to the involute of the first wheel 210, and the water-spraying surface 231 and the water-receiving surface 232 are arranged parallel to the axis of the spoke 230, and the water-spraying surface 231 faces the rotation direction of the water-spraying wheel 200 following the rotation of the rotating shaft 110 to achieve the water-spraying air power of lifting the accumulated water, while the water-receiving surface 232 faces away from the rotation direction of the water-spraying wheel 200 following the rotation of the rotating shaft 110. Specifically, Figure 7As shown, the water-pumping surface 231 includes a first water-pumping surface 2311 and a second water-pumping surface 2312 symmetrical with respect to the axial section of the water-pumping wheel 200, and the angle between the first water-pumping surface 2311 and the second water-pumping surface 2312 and the axial section of the water-pumping wheel 200 is greater than 90°; the back water surface 232 includes a first back water surface 2321 and a second back water surface 2322 symmetrical with respect to the axial section of the water-pumping wheel 200, and the angle between the first back water surface 2321 and the second back water surface 2322 and the axial section of the water-pumping wheel 200 is greater than 90°. By setting the angles of the water-pumping surface 231 and the back water surface 232 on the spoke 230, it is ensured that when the water-pumping wheel 200 rotates following the rotating shaft 110, the accumulated water below can be lifted to both sides of the water-pumping wheel 200, thereby cooperating with the evaporator to achieve the function of free drainage. Optionally, an angle between the first water-pumping surface 2311 , the second water-pumping surface 2312 , the first back water surface 2321 , the second back water surface 2322 and the axial cross section of the water-pumping wheel 200 is 92°-94°.

[0039] Furthermore, if Figure 5 As shown, the second wheel 220 is a wheel-shaped structure, and the second wheel 220 is arranged around the outer side of the first wheel 210, the second wheel 220 is coaxial with the first wheel 210, and the second wheel 220 and the first wheel 210 are fixedly connected by the spokes 230. Specifically, the axial width of the second wheel 220 is the same as the axial width of the outer ring 212 of the first wheel 210, the two ends of the spokes 230 are respectively fixed to the outer side of the outer ring 212 and the inner side of the second wheel 220, and the width of the spokes 230 remains uniform. When the water-pumping wheel 200 rotates following the rotating shaft 110 of the motor 100, the first wheel 210, the spokes 230 and the second wheel 220 rotate synchronously, thereby avoiding vibration and noise during the water-pumping process and providing the required water-pumping effect.

[0040] Optionally, the axial width of the second wheel 220 is 3.6-4.4 mm, that is, the axial width of the outer ring 212 and the width of the spokes 230 are maintained at 3.6-4.4 mm to be the same as the axial width of the second wheel 220, so that the width of the spokes 230 remains uniform, to ensure that when the water-pumping wheel 200 follows the rotation of the rotating shaft 110 of the motor 100, the first wheel 210, the spokes 230 and the second wheel 220 rotate synchronously to ensure water-pumping efficiency.

[0041] Furthermore, if Figure 7As shown, the inner side of the second wheel 220 is provided with a first surface 221 and a second surface 222 which are symmetrical with respect to the axial section of the water-pumping wheel, and the angle between the first surface 221 and the second surface 222 and the axial section of the water-pumping wheel 200 is greater than 90°, so that when the water-pumping wheel 200 rotates synchronously with the rotating shaft 110, the inner side surface of the second wheel 220 cooperates with the water-pumping surface 231 and the water-repelling surface 232 of the spoke 230 to lift the accumulated water to the two sides of the water-pumping wheel 200, and cooperates with the evaporators on both sides of the water-pumping wheel 200 to evaporate the lifted water mist, thereby ensuring the evaporation efficiency without increasing the lift of the accumulated water, and providing a low-noise and high-efficiency drainage-free function. Optionally, the angle between the first surface 221 and the second surface 222 and the axial section of the water wheel 200 is 91°-93°, and is smaller than the angle between the first water-spraying surface 2311, the second water-spraying surface 2312, the first back water surface 2321 and the second back water surface 2322 and the axial section of the water wheel 200.

[0042] Optionally, the inner side diameter of the second wheel 220 is 60-70 mm, and the two ends of the spokes 230 are respectively fixed on the outer side of the outer ring 212 of the first wheel 210 and the inner side of the second wheel 220. Further, the outer side diameter of the second wheel 220 is 62-74 mm, that is, the radial thickness of the second wheel 220 is 2-4 mm, so as to ensure that the accumulated water can be smoothly lifted to both sides when the water wheel 200 rotates, so as to cooperate with the evaporators on both sides to evaporate the lifted water mist and realize the drainage-free function.

[0043] Furthermore, if Figure 2 and Figure 3 As shown, on the motor 100, the top end 111 of the rotating shaft 110 matches the clamping space 214 in the connecting portion 213 of the first wheel 210 in the water-pumping wheel 200. Optionally, the top end 111 of the rotating shaft 110 is a semi-cylindrical configuration to match the semi-cylindrical clamping space 214, so that the user can more easily install the water-pumping wheel 200 on the rotating shaft 110 of the motor 100, and when the motor 100 starts working, there is no relative rotation between the rotating shaft 110 and the connecting portion 213, so the water-pumping wheel 200 can rotate synchronously with the rotating shaft 110 to achieve the water-pumping function.

[0044] Furthermore, if Figure 3 and Figure 8As shown, the motor 100 also includes a fixing screw 120, and a thread 112 is correspondingly provided on the top end 111 of the rotating shaft 110.
