Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a water pumping device and a mobile air conditioner. Background Art

[0002] As a type of air conditioner, mobile air conditioners are different from common split air conditioners in that they integrate the compressor, evaporator and condenser into one air conditioner body. The room temperature can be adjusted by placing the air conditioner body indoors. Because there is only one air conditioner body, it is easy to move and more convenient to use.

[0003] In the prior art, in order to deal with the condensed water generated during the refrigeration operation of the mobile air conditioner, some mobile air conditioners will be equipped with a water tank and a water wheel on the chassis. The water tank is used to collect the condensed water generated during the operation of the mobile air conditioner. The water wheel is usually arranged between the two condensation plates of the condenser and is located in the water tank. The water wheel lifts the water in the water tank by rotation, and the lifted water can fall on the condensation plate and be evaporated by the heat of the condensation plate, thereby consuming the condensed water and dissipating the heat of the condenser. However, the current condensed water consumption efficiency needs to be further improved. Utility Model Content

[0004] One object of the utility model is to provide a water pumping device and a mobile air conditioner which can improve the condensed water consumption efficiency.

[0011] Optionally, the water-pumping wheel is formed with a back water surface corresponding to each water-pumping surface one by one, each back water surface is arranged facing the corresponding water-pumping surface, and the back water surface and the corresponding water-pumping surface are biased towards the same side of the water-pumping wheel.

[0012] Optionally, a sleeve shaft concentric with the water pumping wheel is provided on one side of the water pumping wheel, and the water pumping wheel is connected to the motor shaft of the water pumping motor via the sleeve shaft.

[0013] Optionally, a flat portion and a plurality of convex ribs are provided in the shaft hole of the sleeve shaft, and the sleeve shaft abuts against the motor shaft of the water pumping motor via the flat portion and the plurality of convex ribs.

[0020] The water pumping device of the utility model is provided with a plurality of water pumping surfaces on a water pumping wheel, and one of the two adjacent water pumping surfaces is tilted toward one side of the water pumping wheel, and the other water pumping surface is tilted toward the other side of the water pumping wheel. During the operation of the water pumping wheel, the water pumping surface faces the water in the water tank of the mobile air conditioner during the rotation of the water pumping wheel, and the water pumping surface enters the water in the water tank and then leaves the water as the water pumping wheel rotates. When the water pumping surface leaves the water, the water in the water tank is lifted. During the process of the water pumping surface lifting the water, for the two adjacent water pumping surfaces, one water pumping surface can guide the water to one side of the water pumping wheel, and the other water pumping surface can guide the water to the other side of the water pumping wheel.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] like Figures 1 to 3 As shown, in one embodiment, the mobile air conditioner includes a chassis 100, a condenser 200 and a water pumping device 300. A water tank 101 is provided on the chassis 100, and the water tank 101 is used to receive condensed water of the mobile air conditioner. The water pumping device 300 is arranged on the chassis 100. The water pumping device 300 includes two water pumping wheels 310 and a water pumping motor 320. After the water pumping device 300 is arranged in place on the chassis 100, the water pumping wheels 310 are located in the water tank 101, and the water pumping motor 320 is connected to the water pumping wheels 310 for driving the water pumping wheels 310 to rotate. The rotating water pumping wheels 310 can pump up the water in the water tank 101, so that the pumped water is sprinkled on the condenser 200 and evaporated.

[0038] in addition, Figure 1Only a partial structure of the mobile air conditioner is shown. It can be understood that the mobile air conditioner also includes multiple components such as an evaporator, a compressor, a heat dissipation fan, an air outlet fan, and a structure for guiding condensed water to flow to a water tank. Because for a mobile air conditioner, the above-mentioned components themselves are well known and easy to implement by those skilled in the art. In order not to cover up and blur the utility model points of the present application, the above-mentioned components themselves will not be described in detail.

[0039] Reference Figures 1 to 3 As shown, specifically, the condenser 200 includes a plurality of condensing plates 210, and the water-pumping wheel 310 is arranged between two condensing plates 210. The condenser 200 includes three condensing plates 210, and the three condensing plates 210 are arranged side by side on the chassis 100. The two water-pumping wheels 310 of the water-pumping device 300 are arranged coaxially, that is, the rotating shafts of the two water-pumping wheels 310 coincide. The water-pumping device 300 is installed on the chassis 100 in a manner that the extending direction of the rotating shaft of the water-pumping wheel 310 is parallel to the arrangement direction of the condensing plates 210, so that the two water-pumping wheels 310 can be respectively located between the two condensing plates 210.

[0040] Combination Figures 1 to 5 As shown, taking a water wheel 310 as an example, the water wheel 310 is provided with a plurality of water pumping surfaces 311, which are distributed around the axis of the water wheel 310. The water pumping surfaces 311 are used to face the water in the water tank 101 of the mobile air conditioner to raise the water during the rotation of the water wheel 310. One of the two adjacent water pumping surfaces 311 is inclined toward one side of the water wheel 310, and the other water pumping surface 311 is inclined toward the other side of the water wheel 310.

[0041] Combination Figures 1 to 5 As shown, the water wheel 310 is further provided with a plurality of water-pumping holes 301, and the side of the water-pumping holes 301 facing the water in the water tank 101 of the mobile air conditioner during the rotation of the water wheel 310 forms a water-pumping surface 311. In this embodiment, the water wheel 310 is provided with 28 water-pumping holes 301, that is, 28 water-pumping surfaces 311 are formed.

[0042] Reference Figures 3 to 5 As shown, specifically, the main body of the water wheel 310 is roughly a circular plate structure, and the two sides of the water wheel 310 are two side surfaces distributed along the thickness direction of the water wheel 310, or two side surfaces distributed along the extension direction of the rotating shaft. After the circular plate is punched along the thickness direction to punch out the water-pumping hole 301, the cut surface formed on the remaining part is the water-pumping surface 311, that is, the water-pumping surface 311 participates in forming the water-pumping hole 301. From the overall point of view, the water-pumping surface 311 extends from the axis of the water wheel 310 to the edge of the water wheel 310. Multiple water-pumping surfaces 311 are distributed around the axis of the water wheel 310, that is, distributed along the rotation direction of the water wheel 310.

[0043] Furthermore, the water pumping surface 311 faces the water in the water tank 101 of the mobile air conditioner during the rotation of the water pumping wheel 310. Figure 3 As an example, the water tank 101 (refer to Figure 2 The water wheel 310 is shown as a bottom side of the water wheel 310. The water wheel 310 rotates counterclockwise during operation, so each water-beating surface 311 faces or faces the water in the water tank 101. In other words, the water-beating surface 311 can collide with the water in the water tank 101 during the rotation of the water wheel 310. Therefore, when the water-beating surface 311 submerged in the water of the water tank 101 leaves the water of the water tank 101 as the water wheel 310 rotates, the water in the water tank 101 will be lifted up by the force.

[0044] Reference Figure 4 and Figure 5 As shown, further, one of the two adjacent water-pumping surfaces 311 is inclined toward one side of the water-pumping wheel 310, and the other water-pumping surface 311 is inclined toward the other side of the water-pumping wheel 310. Specifically, for ease of description, the two side surfaces of the water-pumping wheel 310 are referred to as a first side surface and a second side surface. For two adjacent water-pumping surfaces 311 along the rotation direction of the water-pumping wheel 310, one water-pumping surface 311 is inclined toward the first side surface of the water-pumping wheel 310, that is, the entire water-pumping surface 311 can be seen from the first side surface, and the other water-pumping surface 311 is inclined toward the second side surface of the water-pumping wheel 310, that is, the entire water-pumping surface 311 can be seen from the second side surface.

[0045] Combination Figures 1 to 5 As shown, during the operation of the water wheel 310, as the water wheel 310 rotates, a water pumping surface 311 enters the water in the water tank 101 from outside the water, and then leaves the water in the water tank 101 as the water wheel 310 rotates. When the water pumping surface 311 leaves the water, the water in the water tank 101 is lifted. During the process of the water pumping surface 311 lifting the water, the water pumping surface 311 inclined toward the first side of the water wheel 310 can also guide the water toward the first side of the water wheel 310, and the water pumping surface 311 inclined toward the second side of the water wheel 310 can also guide the water toward the second side of the water wheel 310. Because the water-pumping wheel 310 is arranged between the two condensation plates 210, that is, there are two condensation plates 210 respectively located on the first side and the second side of the water-pumping wheel 310, in this way, the water-pumping surface 311 inclined toward the first side of the water-pumping wheel 310 can pump more water toward the condensation plate 210 located on the first side of the water-pumping wheel 310, and the water-pumping surface 311 inclined toward the second side of the water-pumping wheel 310 can pump more water toward the condensation plate 210 located on the second side of the water-pumping wheel 310.

[0046] In the scheme of this embodiment, a plurality of water pumping surfaces 311 are provided in the water pumping wheel 310, and one of the two adjacent water pumping surfaces 311 is tilted toward one side of the water pumping wheel 310, and the other water pumping surface 311 is tilted toward the other side of the water pumping wheel 310. During the operation of the water pumping wheel 310, the water pumping surfaces 311 face the water in the water tank 101 of the mobile air conditioner during the rotation of the water pumping wheel 310. The water pumping surfaces 311 enter the water in the water tank 101 and then leave the water as the water pumping wheel 310 rotates. When the water pumping surfaces 311 leave the water, the water in the water tank 101 is lifted. During the process of the water pumping surfaces 311 lifting the water, for the two adjacent water pumping surfaces 311, one water pumping surface 311 can guide the water to one side of the water pumping wheel 310, and the other water pumping surface 311 can guide the water to the other side of the water pumping wheel 310.

[0047] Therefore, the water wheel 310 can pump more water to the condensation plates 210 on both sides, thereby improving the water consumption efficiency in the water tank 101 and also improving the heat dissipation effect of the condenser 200. In addition, the water pumped to both sides by the water wheel 310 is more uniform, which can fully utilize the heat of the condenser 200 and also can better dissipate the heat of the condenser 200.

[0048] Furthermore, by providing a plurality of water-pumping holes 301 on the water-pumping wheel 310 to form a water-pumping surface 311, the outer edge of the water-pumping wheel 310 is still a complete circular edge, which is beneficial to improving the structural strength of the water-pumping wheel 310 and improving the water-pumping effect.

[0049] In addition, by providing two water pumping wheels 310 , the amount of water pumped can be further increased, thereby further improving the water consumption efficiency in the water tank 101 .

[0050] It should be noted that, in some other embodiments, the water-pumping wheel may also directly cut off the portion from the axis to the edge to form the water-pumping surface, that is, the edge of the water-pumping wheel is discontinuous.

[0051] It should be noted that, in some other embodiments, the water pumping device may also be provided with a water pumping wheel. In addition, the number of water pumping surfaces of the water pumping wheel may also be other numbers, and those skilled in the art may design it as required according to the size of the water pumping wheel.

[0052] Reference Figure 4As shown, further, the width of the water-pumping hole 301 increases along the direction from the end close to the axis of the water-pumping wheel 310 to the end close to the edge of the water-pumping wheel 310. Specifically, the width of the water-pumping hole 301 is the size of the water-pumping hole 301 along the rotation direction of the water-pumping wheel 310. The width of the water-pumping hole 301 at the end close to the axis of the water-pumping wheel 310 is smaller, while the width of the water-pumping hole 301 at the end close to the edge of the water-pumping wheel 310 is larger. The above structure is conducive to improving the water-pumping effect of the water-pumping wheel 310.

[0053] like Figure 4 and Figure 5 As shown, further, the water-pumping surface 311 is arc-shaped, and the arc of the water-pumping surface 311 is convex along the rotation direction of the water-pumping wheel 310. Specifically, during the rotation of the water-pumping wheel 310, an arc-shaped convex surface of the water-pumping surface 311 faces the water tank 101 (refer to Figure 2 water in the form shown).

[0054] By setting the water-pumping surface 311 to be arc-shaped, the water-pumping surface 311 can guide the water to the edge of the water-pumping wheel 310 during the process of the water-pumping surface 311 lifting the water, which helps the water-pumping wheel 310 to pump the water farther, thereby increasing the scattering range on the condenser and facilitating more effective use of the heat of the condenser.

[0055] Reference Figure 4 and Figure 5 As shown, the water-pumping wheel 310 is formed with a back surface 312 corresponding to each water-pumping surface 311, each back surface 312 is arranged facing the corresponding water-pumping surface 311, and the back surface 312 and the corresponding water-pumping surface 311 are inclined to the same side of the water-pumping wheel 310. Specifically, a group of corresponding water-pumping surfaces 311 and back surfaces 312 are two opposite sides of the water-pumping hole 301 distributed along the rotation direction of the water-pumping wheel 310. For a group of corresponding water-pumping surfaces 311 and back surfaces 312, if the water-pumping surface 311 is inclined toward the first side of the water-pumping wheel 310, then the back surface is also inclined toward the first side of the water-pumping wheel 310, and if the water-pumping surface 311 is inclined toward the second side of the water-pumping wheel 310, then the back surface is also inclined toward the second side of the water-pumping wheel 310. Because the back surface 312 and the water-pumping surface 311 face each other, the inclination directions of the back surface 312 and the water-pumping surface 311 are opposite.

[0056] By setting the back surface 312 facing the water-pumping surface 311 to be on the same side of the water-pumping wheel 310 as the corresponding water-pumping surface 311, the back surface 312 can also guide the water in contact to one side of the water-pumping wheel 310 in the same direction as the corresponding water-pumping surface 311. Therefore, in the process of the water-pumping surface 311 lifting the water, the back surface 312 can also guide the water in contact to one side of the water-pumping wheel 310 for the water lifted and flying toward the back surface 312, further increasing the amount of water lifted to both sides by the water-pumping wheel 310, thereby further improving the water consumption efficiency in the water tank 101 and the heat dissipation effect of the condenser 200.

[0057] Reference Figures 3 to 6 As shown, further, a sleeve shaft 313 concentric with the water wheel 310 is provided on one side of the water wheel 310, and the water wheel 310 is connected to the motor shaft of the water pumping motor 320 via the sleeve shaft 313. Specifically, the sleeve shaft 313 and the water wheel 310 are integrally formed, the sleeve shaft 313 is a round rod-shaped structure, one end of the sleeve shaft 313 is connected to the main part of the water wheel 310, and the sleeve shaft 313 is provided with an axial hole 3131, and the axial hole 3131 penetrates the sleeve shaft 313 and the main part of the water wheel 310 along the axial direction.

[0058] Continue to refer to Figures 3 to 6 As shown, further, a flat portion 3132 and a plurality of convex ribs 3133 are provided in the shaft hole 3131 of the sleeve shaft 313, and the sleeve shaft 313 abuts against the motor shaft of the water pumping motor 320 via the flat portion 3132 and the plurality of convex ribs 3133. Specifically, the flat portion 3132 is a structure that makes the circular shape irregular when the circular shape is difficult to fix. In this embodiment, the cross-sectional shape of the shaft hole 3131 is roughly "D"-shaped, the flat portion 3132 is the horizontal side of the "D", and the plurality of convex ribs 3133 are arranged on the curved side of the "D". Although not shown in the figure, it can be understood that the shape of the motor shaft of the water pumping motor 320 matches the shape of the shaft hole 3131, that is, the cross-sectional shape of the motor shaft of the water pumping motor 320 is also "D"-shaped. The motor shaft of the water pumping motor 320 extends into the shaft hole 3131 to complete the assembly with the water pumping wheel 310 , and the flat part 3132 and the convex rib 3133 contact the motor shaft of the water pumping motor 320 to form a fixation in the rotation direction, so that the water pumping wheel 310 can rotate under the drive of the water pumping motor 320 .

[0059] By providing a sleeve shaft 313 on one side of the water pumping wheel 310, the water pumping wheel 310 is connected to the motor shaft of the water pumping motor 320 via the sleeve shaft 313, which is conducive to increasing the connection contact area between the water pumping wheel 310 and the motor shaft of the water pumping motor 320, and helps to improve the connection stability between the water pumping wheel 310 and the motor shaft of the water pumping motor 320. In addition, by providing a convex rib 3133 to abut against and fix the motor shaft of the water pumping motor 320, the other space in the shaft hole 3131 can be larger than the size of the motor shaft of the water pumping motor 320, so that the motor shaft of the water pumping motor 320 and the shaft hole 3131 are assembled more conveniently.

[0060] It should be noted that in some other embodiments, the shaft hole can also be other special-shaped shapes, as long as the motor shaft and the shaft hole of the water pumping motor are fixed in the rotation direction. In addition, the sleeve shaft can be formed separately from the water pumping wheel and then fixed together.

[0061] Reference Figures 1 to 3 , Figures 7 to 9 As shown, further, the water pumping device 300 further includes a motor assembly shell 330. The water pumping motor 320 has a first fitting 321. The motor assembly shell 330 is covered on the outside of the water pumping motor 320, and the motor assembly shell 330 is provided with a second fitting 331 and a third fitting 332. The motor assembly shell 330 is fixedly connected to the water pumping motor 320 through the cooperation of the second fitting 331 and the first fitting 321, and the motor assembly shell 330 is connected to the chassis 100 of the mobile air conditioner through the third fitting 332. The motor assembly shell 330 has a shielding portion 333 located between the water pumping wheel 310 and the water pumping motor 320, and the shielding portion 333 is provided with an avoidance area 3331 to shield the side of the water pumping motor 320 facing the water pumping wheel 310 and allow the motor shaft of the water pumping motor 320 to pass through the avoidance area 3331 and connect with the water pumping wheel 310.

[0062] Reference Figures 1 to 3 , Figures 7 to 9 As shown, specifically, the first matching piece 321 includes two mounting ears respectively arranged on opposite sides of the water pumping motor 320, and the mounting ears are provided with mounting holes. The second matching piece 331 includes two screw columns, and the screw columns are provided with screw holes. The two screw columns correspond to the two mounting ears one by one, and the first matching piece 321 and the second matching piece 331 are fixedly connected via screws passing through the mounting holes and embedded in the screw holes.

[0063] Specifically, the motor assembly shell 330 can be regarded as a box-like structure with bottom and rear openings, and the shielding portion 333 is the front plate of the box-like structure. The water pumping motor 320 is placed into the space surrounded by the motor assembly shell 330 from the bottom opening of the box-like structure.

[0064] Continue to refer to Figures 1 to 3 , Figures 7 to 9As shown, the mounting ears on both sides of the water pumping motor 320 are flat structures, and a through mounting hole is opened along the thickness direction. Two screw columns extending along the top and bottom directions are provided inside the motor assembly shell 330. During the assembly process of the water pumping motor 320 and the motor assembly shell 330, the water pumping motor 320 is placed into the space surrounded by the motor assembly shell 330 from the bottom opening of the motor assembly shell 330, so that the two mounting ears of the water pumping motor 320 fall on the two screw columns respectively, and the two mounting holes are aligned with the two screw holes respectively, and then the screws are passed through the mounting holes and inserted into the screw holes, and the assembly of the water pumping motor 320 and the motor assembly shell 330 is completed. Because the shielding portion 333 is provided with an avoidance area 3331, the motor shaft of the water pumping motor 320 can pass through the shielding portion 333 and be connected to the water pumping wheel 310. At the same time, the shielding portion 333 shields the side of the water pumping motor 320 facing the water pumping wheel 310.

[0065] In the solution of this embodiment, by providing a motor assembly shell 330, providing a first matching piece 321 on the water pumping motor 320, and providing a second matching piece 331 and a third matching piece 332 on the motor assembly shell 330, the motor assembly shell 330 is fixedly connected to the water pumping motor 320 through the matching of the second matching piece 331 and the first matching piece 321, and is connected to the chassis 100 of the mobile air conditioner through the third matching piece 332. The motor assembly shell 330 has a shielding portion 333 located between the water pumping wheel 310 and the water pumping motor 320, and the shielding portion 333 is provided with an avoidance area 3331 to shield the side of the water pumping motor 320 facing the water pumping wheel 310 and allow the motor shaft of the water pumping motor 320 to pass through the avoidance area 3331 and be connected to the water pumping wheel 310.

[0066] Therefore, on one hand, during the use of the water pumping device 300, the motor assembly shell 330 can play a waterproof role for the water pumping motor 320, thereby improving the safety of the water pumping motor 320. On the other hand, the water pumping device 300 can be installed on the chassis 100 as an assembled whole, that is, the water pumping device 300 and the chassis 100 have only one set of mounting structures. When the water pumping motor 320 is inspected and repaired, only one set of mounting structures is operated to dismantle the entire water pumping device 300, without first dismantling the external waterproof shell and then dismantling the motor, thereby improving the convenience of use.

[0067] It should be noted that, in some other embodiments, the first matching piece and the second matching piece may also be other matching fixing structures, such as a snap-fit ​​structure and the like.

[0068] like Figure 8 and Fig. 9As shown, the screw column is provided with two positioning ribs 3311, and the distance between the two positioning ribs 3311 matches the size of the mounting ear to position the mounting ear. Specifically, the two positioning ribs 3311 can clamp the mounting ear of the water pumping motor 320, so as to position the mounting ear of the water pumping motor 320 to an assembly position where the mounting hole is aligned with the screw hole of the screw column, thereby improving the convenience of assembling the water pumping motor 320 and the motor assembly housing 330.

[0069] Reference Figure 1 and Figure 2 , Figures 8 to 10 As shown, the third fitting member 332 includes mounting ears respectively arranged on both sides of the motor mounting shell 330, the mounting ears are provided with mounting holes, and the third fitting member 332 is connected to the chassis 100 of the mobile air conditioner via screws passing through the mounting holes.

[0070] Specifically, the assembly ears on both sides of the motor assembly shell 330 are flat structures, and a through assembly hole is opened along the thickness direction. Two longitudinally extending positioning columns are provided on the chassis 100, and the positioning columns are provided with threaded holes. During the assembly process of the water pumping device 300 and the chassis 100, the water pumping device 300 is placed on the chassis 100, and the two assembly ears of the motor assembly shell 330 fall on the two positioning columns respectively, and the two assembly holes are aligned with the two threaded holes respectively, and then the screws are passed through the mounting holes and embedded in the threaded holes, and the assembly of the water pumping device 300 and the chassis 100 is completed.

[0071] It should be noted that, in some other embodiments, the third matching piece may also be other matching fixing structures, such as a snap-fit ​​structure and the like.

[0072] like Figure 3 and Figure 8 As shown, further, the motor shaft of the water pumping motor 320 is provided with a waterproof sheet 322, and the waterproof sheet 322 matches the avoidance area 3331 to shield the avoidance area 3331. Specifically, the waterproof sheet 322 is a circular sheet, which is concentrically arranged with the motor shaft of the water pumping motor 320, and the circumferential length of the waterproof sheet 322 is greater than the circumferential length of the motor shaft of the water pumping motor 320. In addition, the area of ​​the waterproof sheet 322 is roughly equivalent to the area of ​​the avoidance area 3331, so that the waterproof sheet 322 can shield the avoidance area 3331, thereby playing a waterproof role together with the solid part of the shielding part 333, and improving the waterproof effect.

[0073] like Figure 3 and Figure 8 As shown, further, the motor shaft of the water pumping motor 320 is provided with a positioning piece (not marked in the figure), which is used to abut against the sleeve shaft 313 of the water pumping wheel 310 to prompt the water pumping wheel 310 and the motor shaft of the water pumping motor 320 to be installed in place.

[0074] like Figure 8 and Fig. 9 As shown, further, the motor assembly shell 330 is provided with a wire clamp 334, which is arranged at one end of the motor assembly shell 330 near the tail of the water pumping motor 320, and is used to gather the wires of the water pumping motor 320. Specifically, the wire clamp 334 is an elastic hook, and after the wires of the water pumping motor 320 are gathered, they can be clamped and fixed by the wire clamp 334, thereby preventing the wires from being scattered.

[0075] like Figure 1 , Figures 9 to 11 As shown, further, a clamping groove 3332 is provided at one end of the shielding portion 333 facing the chassis 100 of the mobile air conditioner, and the clamping groove 3332 is used to clamp the assembly protrusion 110 on the chassis 100 of the mobile air conditioner. Specifically, the clamping groove 3332 cooperates with the assembly protrusion 110 to position the installation of the water pumping device 300, and also improves the stability of the installation of the water pumping device 300 on the chassis 100. In addition, the shielding portion 333 and the assembly protrusion 110 jointly shield the side of the water pumping motor 320 facing the water pumping wheel 310, and together play a waterproof effect.
