Conventional water pumps generally discharge water from the wheel side. In order to facilitate the connection of the water outlet pipe, an elbow pipe needs to be added, which increases the overall size of the water pump, occupies a large installation space, and the connection of the elbow pipe increases the number of parts involved in the assembly, increasing the assembly time. Summary of the Utility Model
[0003] The main purpose of the utility model is to propose a water pump structure and an air conditioner, aiming to adjust the water outlet part of the water pump structure, making it convenient to connect the water outlet pipe, eliminating the need to add an elbow pipe, reducing the occupied space, and saving the assembly time.
[0004] To achieve the above object, the water pump structure proposed by the utility model for an air conditioner includes:
[0005] A water pump main body with a pump cavity formed inside. An inlet is provided on the wall of the pump cavity.

[0013] In one embodiment, an installation cavity is formed inside the pump housing, and a motor for driving the impeller is installed in the installation cavity;

[0021] In one embodiment, the cross-sectional area of the second channel segment gradually increases in a direction away from the first channel segment.
[0022] In one embodiment, the cross-sectional area of the end of the extension channel close to the water outlet is larger than the cross-sectional area of the other end of the extension channel.
[0023] The present utility model further provides an air conditioner, including the above-mentioned water pump structure, and the water pump structure at least includes:
[0024] A water pump main body, in which a pump cavity is provided, a water inlet is provided on the wall of the pump cavity, a water outlet is provided at a position where the water pump main body deviates from the pump cavity in a first direction, and an extension channel communicating the water outlet and the pump cavity is provided inside the water pump main body; and

[0042] During the operation of the air conditioner in the refrigeration condition, condensed water will be generated on the surface of the heat exchanger, and the condensed water will drip along the surface of the heat exchanger into the lower condensate tank below. In order to drain the condensed water, a water pump for drainage is installed at the condensate tank of the air conditioner. Conventional water pumps generally discharge water at the wheel edge, that is, the water inlet 1a is at the axial end of the impeller 2, and the water outlet 1b is at the side of the impeller 2. The interval between the two is relatively small. Therefore, in order to facilitate the connection of the outlet pipe, an elbow pipe needs to be added. The elbow pipe straddles the whole water pump, making the overall dimensions of the water pump increase in height and diameter, occupying a large installation space, and the connection of the elbow pipe increases the number of parts involved in the assembly, increasing the assembly time.
[0043] Based on this, the utility model proposes a water pump structure 100 and an air conditioner, which facilitates connection to a water outlet pipe by adjusting the water outlet portion of the water pump structure 100, without adding an elbow, thereby reducing the space occupied and saving assembly time.
[0044] The air conditioner includes an outdoor unit, a water receiving tank, a water pump structure 100 and a water outlet pipe. The water receiving tank is placed at the bottom of the outdoor unit to receive condensed water generated on the surface of the heat exchanger. The water inlet 1a of the water pump structure 100 is inserted downward into the water receiving tank, and the water outlet 1b of the water pump structure 100 is connected to the water outlet pipe to lead the condensed water to the outside for discharge.
[0045] It should be noted that the type of the air conditioner is not limited in the present invention, and it can be a cabinet unit, a wall unit, a central air conditioner, etc.
[0046] Specifically, the water pump structure 100 includes a water pump body 1 and an impeller 2, wherein a pump cavity is arranged inside the water pump body 1, a water inlet 1a is arranged on the wall of the pump cavity, a water outlet 1b is arranged on the water pump body 1 at a position deviating from the pump cavity in a first direction, an extension channel 13 connecting the water outlet 1b and the pump cavity is arranged inside the water pump body 1, the impeller 2 extends axially along the first direction, and the impeller 2 is rotatably installed in the pump cavity.
[0047] In the technical solution of the utility model, the impeller 2 rotates so that water is sucked from the water inlet 1a, and discharged from the water outlet 1b through the pump chamber and the extension channel 13. The water outlet 1b is used to connect to the external water outlet pipe, and the water inlet 1a is used to extend into the water receiving tank of the air conditioner. By setting the water outlet 1b and the pump chamber to deviate in the first direction, the interval between the water outlet 1b and the water inlet 1a is extended compared with the conventional water pump, thereby compensating for the distance difference between the water outlet 1b and the water outlet pipe, thereby providing sufficient space for the connection of the water outlet pipe. The setting of the extension channel 13 extends the water flow passage to ensure the smooth water discharge. As a result, the water pump structure 100 can be connected to the water outlet pipe without the need to install a bend pipe, reducing the number of assembled parts and saving assembly time. In addition, the external dimensions of the water pump structure 100 itself increase slightly or without significant increase, which can save assembly space.
[0048] Based on the above structure, it can be known that the extension channel 13 is to guide the water in the pump chamber to the water outlet 1b, so the extension channel 13 at least partially extends along the axial direction of the impeller 2, that is, at least part of the extension channel extends along the first direction.
[0049] Further, the water inlet 1a is provided at one end of the pump chamber in the first direction, and the water outlet 1b is located on the side where the other end of the pump chamber is located. That is, there is at least the pump chamber between the water inlet 1a and the water outlet 1b, so the distance between the two is greater than the size of the pump chamber in the first direction. For a conventional water pump with wheel-side water outlet, the distance between the water outlet 1b and the water inlet 1a is equal to or less than the size of the pump chamber in the first direction. Therefore, this application has a significant increase compared with the conventional water pump.
[0050] Specifically, the axis where the water inlet 1a is located is perpendicular to the axis where the water outlet 1b is located.
[0051] In this application, the water pump main body 1 is a splicing structure. Specifically, the water pump main body 1 includes a pump housing 11 and an end cover 12. The end cover 12 has a receiving cavity 121 with one end open. The end cover 12 is arranged to cover the open end of the receiving cavity 121 and jointly encloses the pump chamber with the pump housing 11. Among them, the water inlet 1a is provided on the end cover 12, the water outlet 1b is provided on the side of the pump housing 11, and the extension channel 13 is formed inside the pump housing 11. By respectively arranging the water inlet 1a and the water outlet 1b on two components constituting the water pump main body 1, the distance between the two can be made large enough. At the same time, the extension channel can be processed only based on the pump body alone, which is convenient for manufacturing.
[0052] It should be understood that the end cover 12 and the pump body are in sealing cooperation, and the two can be assembled by means of step positioning and seal ring cooperation. This application does not elaborate on this.
[0053] Further, an installation cavity 111 is formed inside the pump housing 11, and a motor 3 for driving the impeller 2 is installed in the installation cavity 111; the extension channel 13 is located on the side of the installation cavity 111. The main body of the motor 3 is located inside the installation cavity 111, and the output shaft of the motor 3 can extend out of the installation cavity 111 and extend into the receiving cavity 121 of the end cover 12 to be connected with the impeller 2. The extension channel 13 and the installation cavity 111 are independent of each other and not connected, so as to ensure the sealing performance of the installation cavity 111 and protect the internal motor 3.
[0054] The pump housing 11 can be integrally formed or combined. In some embodiments, the pump housing 11 is spliced and synthesized by an intermediate shell and a bottom shell. Please refer to Figure 4 , one side of the intermediate shell is open and spliced with the bottom shell, which is convenient for the installation of the motor 3. The extension channel 13 is integrated on the intermediate shell. It should be understood that the bottom shell and the intermediate shell should be in sealing cooperation, and the two can be through step positioning and seal ring cooperation. The present utility model does not elaborate on this.
[0055] It should be noted that the present utility model does not limit the specific form of the extension channel 13. A circular chamber can be provided around the installation cavity 111 as the extension channel 13, or a tubular passage can be provided on the side of the installation cavity 111 as the extension channel 13, without affecting the diversion function of the extension channel 13.
[0056] Please refer to Figure 2 , an impeller passage 2a is defined between the impeller 2 and the inner side of the end cap 12, and the impeller passage 2a communicates with the extension channel 13; a groove 14 is formed in the inner wall of the pump chamber, and the groove 14 is located at the connection between the impeller passage 2a and the extension channel 13. The groove 14 serves to guide the turning of the water flow. Preferably, the groove 14 is formed as an arc-shaped groove, so that the transition is smoother.
[0057] Please refer to Figure 3 , in this embodiment, a part of the end cap 12 protrudes to form the groove 14 on the inner side of the end cap 12.
[0058] In an embodiment of the present utility model, the impeller passage 2a is annularly arranged, and in a first direction, the cross-sectional area of the impeller passage 2a is variably arranged.
[0059] Furthermore, the extension channel 13 includes a plurality of extension segments, and at least some of the extension segments have different directions. Such an arrangement facilitates adapting to water inlets 1a and outlets 1b with different orientations, and at the same time, the shape of the water pump main body 1 can be closely fitted by relying on the orientation change of the extension segments.
[0060] Please refer to Figure 4 , in an embodiment of the present utility model, the extension channel 13 includes a first channel segment 131 and a second channel segment 132. The first channel segment 131 is located on the side of the pump chamber away from the water inlet 1a and extends in a first direction, and the first channel segment 131 communicates with the pump chamber; the second channel segment 132 extends in a second direction for communicating with the water outlet 1b. That is, the extension channel 13 is L-shaped, and the second channel segment 132 adapts to the water outlet direction of the water outlet 1b.
[0061] It should be understood that the connection between the first channel segment 131 and the second channel segment is in an arc transition.
[0062] Moreover, the cross-sectional area of the second channel segment 132 gradually increases in a direction away from the first channel segment 131. That is, the second channel segment 132 is in a trumpet shape, which is beneficial to increasing the water flow rate and flow rate.
[0063] In this embodiment, the cross-sectional area of the first channel segment 131 is uniformly arranged in the first direction, an arc for transition is provided at its end, and its side is communicated with the second channel segment 132.
[0064] Furthermore, the cross-sectional area of the end of the extension channel 13 close to the water outlet 1b is larger than the cross-sectional area of the other end of the extension channel 13, so as to improve the water outlet effect.
[0065] In the technical solution of the present utility model, the projection of the extension channel 13 on the horizontal plane is located on the side of the pump chamber. And, a connecting pipe 112 is provided on the side of the pump housing 11, the end of the connecting pipe 112 serves as the water outlet 1b, and the inside of the connecting pipe 112 serves as a part of the extension channel 13. Such a setting provides sufficient assembly space around the water outlet 1b.
[0066] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
