[0056] The following embodiments of the technical solution of the present application are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

[0058] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0059] At present, the chassis and side panels of the outdoor unit are usually fixedly connected by multiple screws. This screw connection method not only requires more materials, but also is cumbersome to operate, thus reducing the production efficiency of the outdoor unit.

[0060] In order to solve the above technical problems, the embodiment of the present application provides an outdoor unit and a heat pump device. The outdoor unit and the heat pump device provided by the embodiment of the present application will be described in detail with reference to the accompanying drawings.

[0061] Heat pump equipment is a device that exchanges heat through refrigerant, which can be applied to air conditioners, water heaters, floor heating, etc. Heat pump equipment usually includes a compressor, a hot water heat exchange device, a throttling device, an outdoor heat exchanger, a water tank and a circulating water pump. When the heat pump equipment is working, the refrigerant is compressed by the compressor into a high-temperature and high-pressure gas, and the high-temperature and high-pressure gas enters the hot water heat exchanger. The circulating water pump pumps the water in the water tank to the hot water heat exchanger for heat exchange with the high-temperature and high-pressure gas, and the hot water after heat exchange flows back to the water tank for use. After the refrigerant after the hot water heat exchanger is throttled by the throttling device, a low-temperature and low-pressure liquid is formed. The low-temperature and low-pressure liquid refrigerant evaporates in the outdoor heat exchanger, absorbs heat from the outside air, and is converted into a gaseous refrigerant and returns to the compressor. Among them, the outdoor heat exchanger is arranged outdoors in the form of an outdoor unit. Since the compressor, the hot water heat exchange device, the throttling device, the outdoor heat exchanger, the water tank and the circulating water pump are not the focus of this application, they will not be described in detail.

[0062] See also Figure 1 The outdoor unit includes a chassis 1, side panels 2 and a top cover (not shown). The chassis 1 is the basic component of the outdoor unit and bears the weight of the entire outdoor unit. The chassis 1 is usually made of sheet metal, so it can reduce weight while having high strength. Of course, designers can also use other high-strength metal parts to process and manufacture the chassis 1 according to actual needs. Figure 2 In order to increase the rigidity of the chassis 1, the outer periphery of the chassis 1 may be provided with a flange 102 by stamping or the like. In order to further increase the rigidity of the chassis 1, see Figure 1 The middle part of the chassis 1 may also be formed into a recessed portion 101 by stamping or the like, and a plurality of protrusions 1011 may be provided on the recessed portion 101. The embodiment of the present application does not specifically limit the size, shape and arrangement of the protrusions 1011. For example, Figure 1As shown, three rectangular protrusions 1011 are provided on the recessed portion 101 . Figure 1 It can be seen that the protrusion 1011 protrudes in the opposite direction to the depression 101. The chassis 1 can be in various shapes. For example, the shape of the chassis 1 can be Figure 1 The rectangle in the figure is not specifically limited in the embodiments of the present application.

[0063] The top cover is spaced above the bottom plate 1. The side plate 2 surrounds the bottom plate 1 and the top cover to define a chamber for accommodating components such as the outdoor heat exchanger. The side plate 2 can be an integral structure or a split structure. When the side plate 2 is a split structure, Figure 1 The rectangular chassis 1 shown can be provided with a side panel 2 at the front, back, left, and right sides of the chassis 1, that is, a total of four side panels 2 are provided. It can be understood that for chassis 1 of different shapes, a corresponding number of side panels 2 can be provided. Similar to the chassis 1, considering lightweight design, structural strength and reduced processing difficulty, the top cover and the side panels 2 can also be made of sheet metal.

[0064] The side panel 2 includes an outer panel 21 and an inner panel 22 connected to each other; the inner panel 22 is located between the chassis 1 and the outer panel 21. In other words, the outer panel 21 is closer to the outside of the outdoor unit than the inner panel 22, so it can cover the inner panel 22, making the outdoor unit have a simpler appearance. The inner panel 22 can serve as the installation base for the clamp 11 or the connector 221, that is, the connector 221 or the clamp 11 can be installed on the side panel 2 through the inner panel 22. Correspondingly, the clamp 11 or the connector 221 can also be set on the chassis 1. Specifically, see Figure 1 , a connector 221 may be provided on the inner plate 22 , and a clamping member 11 may be provided on the chassis 1 . Alternatively, a clamping member 11 may be provided on the inner plate 22 , and a connector 221 may be provided on the chassis 1 .

[0065] An escape space 3 for installing the plug-in component 221 or the clamping component 11 is reserved between the inner plate 22 and the outer plate 21, which can facilitate the processing of fixing the plug-in component 221 or the clamping component 11 on the inner plate 22. The escape space 3 can be formed by setting a connecting plate 23 connecting the inner plate 22 and the outer plate 21. Figure 2 For example, the inner plate 22 and the connecting plate 23 can be processed and the avoidance space 3 can be formed by two bending processes. In order to facilitate the disassembly between the side plate 2 and the chassis 1, see Figure 4In the height direction of the outdoor unit, the connecting plate 23 is lower than the bottom surface of the chassis 1 and higher than the bottom surface of the recessed portion 101. That is, the inner plate 22 has a downwardly protruding holding structure relative to the chassis 1, and a working space is reserved between the holding structure and the mounting surface 4 of the chassis 1. In this way, when the side plate 2 needs to be removed, the inner plate 22 can be directly grasped by hand, and then force is applied to overcome the clamping force of the clamping portion 111 clamping the plug connector 221, so that the side plate 2 can be removed by hand without using any tools.

[0066] The embodiment of the present application can realize screwless connection between the chassis 1 and the side panel 2 of the outdoor unit by clamping the connector 221 on the chassis 1 and the inner panel 22 with the clamping member 11, that is, a reliable connection between the side panel 2 and the chassis 1 can be achieved without screws, thereby avoiding the problem of large amount of materials required for screw connection and cumbersome operation, and can effectively improve the production efficiency of the outdoor unit.

[0067] In addition, it should be noted that see Figure 2 When the outer periphery of the chassis 1 has a flange 102, a limiting hole 1021 is provided at the flange 102 corresponding to the plug-in component 221 or the clamping component 11. The limiting hole 1021 can provide a movement channel for the plug-in component 221 or the clamping component 11 on the one hand, and can also limit the movement of the plug-in component 221 or the clamping component 11 in the up-down and left-right directions on the other hand.

[0068] like Figure 2 As shown, the clamping member 11 may include two clamping portions 111 disposed opposite to each other, and the clamping portions 111 are used to clamp the plug connector 221. The clamping portion 111 has a fixed end 1111 and a cantilever end 1112; the fixed end 1111 is fixedly connected to the chassis 1, and can provide mounting support for the cantilever end 1112, and can make the cantilever end 1112 swing relative to the fixed end 1111. Since the cantilever end 1112 itself has flexibility, the cantilever end 1112 deformed by external force will show a tendency to return to the original position, so that when the plug connector 221 is inserted between the two cantilever ends 1112, the two clamping portions 111 can provide a clamping force for clamping the plug connector 221. In order to increase the clamping force, the distance between the two cantilever ends 1112 can also be set to be smaller than the distance between the two fixed ends 1111, so that the clamping portion 111 forms a structure similar to a figure eight. In this way, the cantilever end 1112 can achieve a greater deformation relative to the fixed end 1111, thereby obtaining a greater clamping force to restore to the original position.

[0069] On the basis of the structure of the above-mentioned clamping member 11, the clamping member 11 may further include a guide portion 112 for receiving the plug-in connector 221. The guide portion 112 is fixedly connected to the cantilever end 1112. In the direction toward the plug-in connector 221, the distance between the two guide portions 112 gradually increases. When the plug-in connector 221 moves relative to the clamping member 11, if the guide portion 112 and the cantilever end 1112 are misaligned, the plug-in connector 221 will first contact the guide portion 112, and under the action of the guide portion 112, move toward the cantilever end 1112 until it is engaged with the cantilever end 1112. In this way, the accurate engagement of the plug-in connector 221 with the clamping member 11 can be achieved, and the accurate installation of the side panel 2 and the chassis 1 can be achieved.

[0070] Please continue to see Figure 2 In some embodiments of the present application, the clamping member 11 may further include a connecting portion 113. The connecting portion 113 is vertically arranged and fixedly connected to the chassis 1, and the connecting portion 113 is fixedly connected to the fixed ends 1111 of the two clamping portions 111. Compared with the fixed end 1111 of the clamping portion 111 being directly connected to the chassis 1, resulting in a smaller connection surface and prone to failure such as fracture, the embodiment of the present application is fixedly connected to the chassis 1 through the connecting portion 113, and then the fixed end 1111 of the clamping portion 111 is fixedly connected to the connecting portion 113, which can increase the connection surface of the fixed end 1111 and improve the connection strength.

[0071] It should be noted that when the clamping member 11 is installed on the chassis 1, the installation position of the connecting portion 113 can be in different forms. In a possible implementation, the connecting portion 113 is farther away from the plug-in connector 221 than the cantilever end 1112. In other words, the cantilever end 1112 is located between the plug-in connector 221 and the connecting portion 113, see Figure 2 Thus, when the plug-in connector 221 is moved relative to the clamp 11 , the plug-in connector 221 first contacts the cantilever end 1112 in this case.

[0072] In another possible implementation, the connection portion 113 may be closer to the connector 221 than the cantilever end 1112. In other words, the connection portion 113 is located between the connector 221 and the cantilever end 1112. In this way, when the connector 221 is moved relative to the clamp 11, the connector 221 first contacts the connection portion 113 in this case. Therefore, in order to prevent the connection portion 113 from blocking the connector 221, an avoidance hole 1131 for the connector 221 to pass through is provided on the connection portion 113. In this way, the connector 221 first passes through the avoidance hole 1131 of the connection portion 113 and then contacts the cantilever end 1112. It can be understood that, in addition to playing a role of avoidance, the avoidance hole 1131 can also limit the connector 221 in the front-to-back and left-to-right directions, further improving the installation accuracy of the side panel 2 and the chassis 1.

[0073] In order to further improve the connection strength between the clamping member 11 and the chassis 1, see Figure 2 The clamping member 11 may further include a mounting portion 114. The mounting portion 114 may be a plate-shaped structure having a large area, for example Figure 2 and Figure 3 The mounting portion 114 can be fixedly connected to the chassis 1 by gluing, welding, etc. At this time, the connecting portion 113 is fixedly arranged on the mounting portion 114, such as Figure 2 As shown, the lower end of the connecting portion 113 is fixedly connected to the mounting portion 114 , and the left and right ends of the connecting portion 113 are respectively connected to a fixed end 1111 of the clamping portion 111 .

[0074] It should be noted that the clamping member 11 is a special-shaped member. If the components are first processed and manufactured separately using a split structure and then the components are fixedly connected, the processing difficulty, manufacturing cost and production efficiency will be significantly increased. Therefore, in some embodiments of the present application, the clamping portion 111, the guide portion 112, the connecting portion 113 and the mounting portion 114 can be formed by integral stamping. In this way, the clamping member 11 can be processed and manufactured at low cost and high efficiency.

[0075] The connector 221 can adopt a variety of structural forms, for example, a rod-shaped structure, a tubular structure, a block structure, a conical structure, etc. Considering factors such as the degree of ease of processing, structural strength, and processing economy, in some embodiments of the present application, the connector 221 can adopt a pin. One end of the connector 221 close to the inner plate 22 can be fixedly connected to the inner plate 22, and the other end protrudes from the inner plate 22. A slot 2211 can be provided on the outer periphery of the connector 221 corresponding to the cantilever end 1112, and the slot 2211 is used to position the cantilever end 1112 of the clamping portion 111. When the connector 221 is inserted between the two cantilever ends 1112, the end of the cantilever end 1112 can be inserted into the slot 2211, so that the cantilever end 1112 and the connector 221 are clamped more tightly. The slot 2211 on the outer periphery of the connector 221 can be set to two, and the two slots 2211 correspond to the two cantilever ends 1112 respectively. Considering the convenience of processing, the slot 2211 can be arranged around the outer circumference of the connector 221 .

[0076] When the connector 221 is not inserted between the two cantilever ends 1112, two different states may exist between the two cantilever ends 1112. Figure 3As shown, when the connector 221 is not inserted between the two cantilever ends 1112, the two cantilever ends 1112 are spaced apart and the distance between them is less than the diameter of the connector 221. In this case, when the connector 221 is inserted between the two cantilever ends 1112, the two cantilever ends 1112 continue to expand on the basis of the original spacing under the action of the connector 221 until the distance between the two cantilever ends 1112 is equal to the diameter of the connector 221. In the second embodiment of the present application, when the connector 221 is not inserted between the two cantilever ends 1112, the two cantilever ends 1112 abut against each other. In this case, when the connector 221 is inserted between the two cantilever ends 1112, the two cantilever ends 1112 are first separated, and then the distance between them is gradually expanded under the action of the connector 221 until the distance between the two cantilever ends 1112 is equal to the diameter of the connector 221. It can be understood that since the cantilever end 1112 in the second embodiment deviates from the original position to a greater extent, the connection between the side panel 2 and the chassis 1 in the second embodiment is tighter than that in the first embodiment, that is, the clamping force of the clamping portion 111 clamping the connector 221 is greater.

[0077] In addition, it can be understood that, for the two cantilever ends 1112 arranged at intervals, when the plug connector 221 is provided with a clamping slot 2211, the distance between the bottoms of the clamping slot 2211 is greater than or equal to the distance between the two cantilever ends 1112. In this way, when the plug connector 221 is inserted between the two cantilever ends 1112, it can be ensured that the cantilever ends 1112 tightly clamp the plug connector 221.
