[0038] 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.

[0040] 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.

[0041] For ease of description, spatial relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "front side", "lower side", "back side", "upper side", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure.

[0042] At present, the top cover and the side plate 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.

[0043] 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.

[0044] 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, a circulating water pump and a cooling fan. 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 and the cooling fan can be set 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, the circulating water pump and the cooling fan are not the focus of this application, they will not be described in detail.

[0045] The following combination Figures 1 to 4 The specific structure of the outdoor unit is introduced in detail.

[0046] See also Figure 1 , Figure 1The top cover and side panels of an outdoor unit provided in an embodiment of the present application are separated. The outdoor unit includes a top cover 1, a side panel 2 and a chassis (not shown). The chassis is the base of the outdoor unit and bears the weight of the entire outdoor unit. The top cover 1 is arranged above the chassis. The side panel 2 surrounds the chassis and the top cover 1 to define a chamber for accommodating components such as an outdoor heat exchanger and a cooling fan. For example, Figure 1 The side panel 2 located at the front side of the top cover 1 is shown. The top cover 1, the side panel 2 and the chassis are usually made of sheet metal, so they can reduce weight while having high strength. Of course, designers can also use other high-strength metal parts to process and manufacture the top cover 1, the side panel 2 and the chassis according to actual needs. The top cover 1, the side panel 2 and the chassis can be in various shapes. For example, the shape of the top cover 1 and the side panel 2 can be Figure 1 The quadrilateral in the embodiment of the present application is not specifically limited thereto.

[0047] As can be seen from the above, currently, the top cover 1 and the side panel 2 are connected by screws, which not only requires a large number of screws, but also requires corresponding manual screwdrivers or electric screwdrivers, that is, more materials are required, and the operation of installing the screws is boring and cumbersome, which consumes a lot of manpower costs and reduces the production efficiency of the outdoor unit.

[0048] Therefore, the present application forms a limiting protrusion 11 and a limiting groove 12 on the top cover 1, and sets a limiting member 22 on the connecting portion 21 of the side panel 2, so as to realize a screwless connection between the top cover 1 and the side panel 2 through the cooperation of the limiting member 22 with the limiting protrusion 11 and the limiting groove 12.

[0049] See also Figure 1 and Figure 2 , Figure 2 The embodiment of the present application provides a partial cross-sectional view of a top cover and a side panel of an outdoor unit after assembly. The side panel 2 includes a side panel body 20 , a connecting portion 21 and a stopper 22 .

[0050] When the side panel 2 is the side panel 2 on the front side of the indoor unit, Figure 1 As shown, a ventilation hole 201 can be provided on the side plate body 20, and a guide ring 3 is provided on the inner side of the side plate body 20 corresponding to the ventilation hole. The guide ring 3 can play a certain role in guiding the airflow generated by the cooling fan in the outdoor unit to flow out of the outdoor unit more smoothly. At the same time, a grille 4 can be provided on the outer side of the side plate body 20 corresponding to the ventilation hole 201. The grille 4 serves as a barrier for the ventilation hole 201, which can prevent foreign objects such as mosquitoes from entering the outdoor unit and avoid affecting the normal operation of the indoor unit. In addition, the grille 4 can also beautify the appearance of the outdoor unit.

[0051] The connection part 21 is used as a mounting carrier of the stopper 22 and is at least partially disposed on the top of the side plate body 20. The connection part 21 can be fixedly connected to the side plate body 20 by welding or the like. Considering the processing convenience, the connection part 21 can also be formed by bending the side plate body 20. For example, see Figure 1 , the edge of the side plate body 20 can be bent as a whole to form a connecting portion 21 surrounding the edge of the side plate body 20. Figure 1 The top and both left and right sides of the middle side panel body 20 are formed with connecting parts 21. The connecting part 21 located at the top of the side panel body 20 can be connected to the top cover 1, and the connecting parts 21 located on both sides of the side panel body 20 can be connected to other adjacent side panels 2. The connecting part 21 can be made of sheet metal. Of course, the designer can also use other materials to process and manufacture the connecting part 21 according to factors such as connection strength and weight requirements, and this application does not make specific restrictions on this.

[0052] The stopper 22 is fixed to the lower side of the connecting portion 21 and partially protrudes from the connecting portion 21. The stopper 22 can be a plastic structural member or a metal structural member, and the shape of the stopper 22 can be a block or a column, etc. The stopper 22 can be integrally formed with the connecting portion 21, or can be fixedly connected to the connecting portion 21 by gluing or other methods.

[0053] When the limiting member 22 is placed in the limiting groove 12, the connecting portion 21 can be limited by the limiting protrusion 11 and cannot move upward freely. Figure 3 , Figure 3 yes Figure 2 The limiting protrusion 11 is located above the limiting groove 12 and is further back than the limiting groove 12 on the top cover 1, that is, the limiting protrusion 11 is located on the upper side of the limiting groove 12 and is staggered with the limiting groove 12, so that the limiting groove 12 can be at least partially exposed. Figure 3 The end of the limiting protrusion 11 has a first stop surface 111. When the limiting member 22 is placed in the limiting groove 12, the first stop surface 111 can be matched with the top surface of one end of the limiting member 22 protruding from the connecting portion 21, that is, the first stop surface 111 of the limiting protrusion 11 is located on the upward movement path of one end of the limiting member 22 protruding from the connecting portion 21, which can prevent the limiting member 22 from freely moving toward the upper side of the outdoor unit, and further prevent the connecting portion 21 and the side plate 2 from freely moving toward the upper side of the outdoor unit.

[0054] See also Figure 4 , Figure 4 yes Figure 2Schematic diagram of the enlarged structure of part I in another outdoor unit. Considering the convenience of processing the limiting protrusion 11 and improving the durability of the limiting protrusion 11, the limiting protrusion 11 can be set slightly longer. At this time, in order to ensure that the limiting member 22 can be smoothly placed in the limiting groove 12, the embodiment of the present application can also set an avoidance notch 222 at the end of the limiting protrusion 11 corresponding to the top surface of the limiting member 22. The depth and shape of the avoidance notch 222 can be flexibly designed according to the shape structure of the limiting protrusion 11, and the present application does not make specific restrictions on this.

[0055] Please continue to see Figure 3 The side of the limiting protrusion 11 close to the side plate 2 is a second stop surface 112, and the second stop surface 112 can be a plane or a curved surface. Figure 3 As shown, in order to prevent the edges and corners of the limiting protrusion 11 from scratching people when installing and using the outdoor box, the limiting protrusion 11 can be provided with a circular arc transition structure such as a chamfer or a rounded corner. In this case, the second stop surface 112 can be a curved surface. The side wall surface of the limiting groove 12 away from the first stop surface 111 is the third stop surface 121, that is, Figure 3 The side wall surface on the right side of the middle limiting groove 12 is a third stop surface 121. The end of the connecting portion 21 close to the limiting protrusion 11 has a first end surface 211, that is, Figure 3 The end face of the position-limiting member 22 adjacent to the position-limiting protrusion 11 is a first end face 211. The end of the position-limiting member 22 away from the position-limiting protrusion 11 has a second end face 221, that is, Figure 3 The right end surface of the middle limiting member 22 is a second end surface 221 .

[0056] When the limiting member 22 is placed in the limiting groove 12, the first end surface 211 and the second end surface 221 are matched with the second stop surface 112 and the third stop surface 121 respectively. Figure 3 , the second stop surface 112 of the left limiting protrusion 11 is located on the path of the connection part 21 moving to the left, and the third stop surface 121 of the right limiting groove 12 is located on the path of the limiting member 22 moving to the right. When the connection part 21 moves to the left, the second stop surface 112 of the left limiting protrusion 11 contacts the first end surface 211 of the connection part 21, which can limit the side plate 2 from moving toward the rear side of the outdoor unit. When the limiting member 22 moves to the right, the third stop surface 121 of the right limiting groove 12 contacts the second end surface 221 of the limiting member 22, which can limit the side plate 2 from moving toward the front side of the outdoor unit. In summary, the present application can limit the limiting member 22 in both the upper and lower side directions and the front and rear side directions toward the outdoor unit, thereby preventing the side plate 2 from moving significantly in both the upper and lower side directions and the front and rear side directions toward the outdoor unit.

[0057] It is understandable that in order to allow the limiting member 22 to be smoothly inserted into the limiting groove 12, the distance between the second stop surface 112 and the third stop surface 121 is greater than the distance between the first end surface 211 and the second end surface 221. In this way, when the side panel 2 is installed on the top cover 1, it is only necessary to tilt the side panel 2, extend the limiting member 22 obliquely into the limiting groove 12, and then put the tilted side panel 2 straight, so that the side panel 2 and the top cover 1 can be connected without screws.

[0058] It can be seen that the present application scheme can realize screwless connection between the top cover 1 and the side panel 2 of the outdoor unit through the cooperation between the connecting part 21 and the limiting member 22 of the side panel 2 and the limiting protrusion 11 and the limiting groove 12 of the top cover 1, that is, reliable connection between the top cover 1 and the side panel 2 can be achieved without screws, thereby avoiding the problems of large amount of materials required for screw connection and cumbersome operation, and can effectively improve the production efficiency of the outdoor unit.

[0059] It should be noted that the height of the side wall of the limiting groove 12 is less than or equal to the height of the limiting member 22. In this way, when the limiting member 22 is placed in the limiting groove 12, the bottom of the limiting groove 12 can abut against the bottom of the limiting member 22. In other words, after the side panel 2 is connected to the top cover 1, the bottom of the limiting groove 12 can provide effective support for the side panel 2.

[0060] In addition, in order to make the entire outdoor unit look neat and regular after the side panel 2 is connected to the top cover 1, and to avoid the appearance of protrusions or other irregular structures on the surface, in some embodiments of the present application, the first portion 10 of the top cover 1 with the limiting groove 12 can be set to be lower than other portions of the top cover 1. For example, see Figure 1 , the first part 10 on the right side of the top cover 1 is recessed downward relative to the surface of the top cover 1, so that the part of the top cover 1 close to the front side of the outdoor box is stepped. In this way, when the limiting member 22 is placed in the limiting groove 12, after the side panel 2 and the top cover 1 are connected, the connecting part 21 of the side panel 2 is located in the first part 10 and can be flush with the other parts of the top cover 1 except the first part 10, so that the entire appearance of the outdoor unit is regular.

[0061] Finally, in order to improve the connection reliability between the side panel 2 and the top cover 1, the embodiment of the present application can also arrange multiple limit members 22 at intervals on the connection portion 21 of the side panel 2, and correspondingly, arrange multiple limit grooves 12 and limit protrusions 11 matching the limit members 22 on the top cover 1. Figure 1 The exemplary embodiment shows that three limiting members 22 and three limiting grooves 12 corresponding to the three limiting members 22 are provided. It can be understood that when the side panel 2 is connected to the top cover 1, the plurality of limiting members 22 cooperate with the plurality of limiting grooves 12 and the limiting protrusions 11, and even if the limiting members 22 or the limiting protrusions 11 are damaged, the effective connection between the side panel 2 and the top cover 1 can be ensured.

[0062] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application is described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application.
