[0034] like Figures 1 to 4 As shown, Figure 1In the first aspect of this utility model, a housing assembly is provided, including a housing 10 and a protective net 17. The housing 10 has a return air vent 113. The housing 10 is provided with a mating part 114 and a first connecting part. The mating part 114 is disposed around the return air vent 113. The protective net 17 covers the return air vent 113. The edge of the protective net 17 is provided with a plug-in part 171 and a second connecting part. The plug-in part 171 is plugged into the mating part 114. The mating part 114 supports the plug-in part 171 and restricts the axial movement of the plug-in part 171 along the return air vent 113. A connector is disposed on the side of the protective net 17 away from the mating part 114. The protective net 17 is detachably connected to the housing 10 through the connector.

[0035] Understandably, the housing assembly can be the outer shell of the outdoor unit 1 of the HVAC equipment. The interior of the housing 10 is used to house internal equipment such as the compressor, heat exchanger, fan, and electrical control devices. The housing 10 can be assembled from multiple sheet metal parts. Air outlets and return air inlets 113 can be respectively provided on the front and rear sides of the housing 10, forming a heat exchange channel between the air outlets and return air inlets 113. The heat exchanger is placed in the heat exchange channel and is positioned close to the return air inlet 113. The fan is placed in the heat exchange channel to provide heat exchange for the heat exchanger and is positioned close to the air outlet. To protect the heat exchanger and other internal equipment, a protective net 17 can be installed at the return air inlet 113 to prevent the heat exchanger from being bumped or scratched. The protective net 17 is adapted to the shape of the return air vent 113. The outer contour of the protective net 17 is roughly rectangular and is formed by welding multiple metal wires or metal rods. The edge of the protective net 17 can be detachably connected to the housing 10. To facilitate the installation and disassembly of the protective net 17, a support part is provided on the housing 10. The mating part 114 can be a hole-shaped structure, an L-shaped solid structure, or a U-shaped solid structure. Correspondingly, the insertion part 171 on the protective net 17 can be a rod-shaped structure or a insert structure, so that the insertion part 171 can be inserted into the hole or groove of the mating part 114, so that the insertion part 171 and the mating part 114 are inserted and mated. At the same time, the mating part 114 also has an upward-facing support surface in the height direction of the housing 10. The support surface abuts against the insertion part 171 to support the insertion part 171, thereby supporting the protective net 17. A second connecting part in the form of bolt holes or through holes can be provided on the other side along the length direction of the protective net 17, and it is connected to the first connecting part on the box body 10 through a connector. The connector secures one side of the protective net 17 to the box body 10 to prevent the protective net 17 from falling off accidentally. During installation, the side of the protective net 17 with the plug-in part 171 can be inserted into the mating part 114 for plug-in connection, and then the other side is connected to the box body 10 through the connector. The installation is convenient and requires few connectors.

[0036] The housing assembly proposed in this utility model has a protective net 17 that is easy to install and disassemble. One side of the protective net 17 is connected to the housing 10 through a connector. The insertion part 171 on the other side of the protective net 17 is inserted and engaged with the mating part 114 on the housing 10. The mating part 114 supports and limits the protective net 17, so that the protective net 17 can be installed by inserting one side into the support part and fastening the other side through the connector. There is no need to use a large number of screws to fasten the two or four sides of the protective net 17, making the installation convenient and quick.

[0037] like Figure 2 As shown, in some embodiments of the present invention, the mating part 114 includes a pin hole 1141, and the insertion part 171 includes a pin, which is inserted into the pin hole 1141.

[0038] Understandably, pin holes 1141 can be made on the housing 10. Pin holes 1141 can be rectangular or circular. Pin holes 1141 can be located on the bottom or left / right sides of the return air inlet 113. The axial direction of pin holes 1141 can be parallel to the return air inlet 113, so that the protective net 17 covers the return air inlet 113 after installation. The pin has a cylindrical structure and can be the edge part of the protective net 17. That is, the protective net 17 is composed of multiple rods, and the ends of the rods form pins, which are inserted into the pin holes 1141 to achieve the insertion and engagement of the protective net 17 with the housing 10.

[0039] like Figure 2 As shown, in some embodiments of the present invention, the housing 10 includes a back plate 115 located on the periphery of the return air vent 113, and the housing 10 also includes a fixing plate 1151, which is connected to the back plate 115, and a pin hole 1141 is formed between the fixing plate 1151 and the back plate 115.

[0040] Understandably, the enclosure 10 can be composed of a back panel 115 and two side panels arranged opposite each other. A return air vent 113 is provided on the back panel 115, and a fixing plate 1151 is provided on the back panel 115. The fixing plate 1151 can be an arc-shaped plate structure, with its two ends connected to the back panel 115, and a raised first part in the middle spaced from the back panel 115, forming a pin hole 1141. Specifically, the fixing plate 1151 can be formed by sheet metal shearing and stamping of the back panel 115, that is, by cutting two openings in the back panel 115 and stamping a raised portion of the back panel 115 between the two openings; this portion is the first part. The fixing plate 1151, being an integral structure with the back panel 115, has higher strength and better reliability.

[0041] like Figure 2 and Figure 4 As shown, in some embodiments of this utility model, along the axial direction of the pin hole 1141, the first end of the pin hole 1141 is used for the insertion of a pin, and the second end of the pin hole 1141 is in a closed state or a partially closed state.

[0042] Understandably, a solid structure can be provided at the end of the pin hole 1141 opposite to the insertion end of the pin to close the second end of the pin hole 1141, thereby preventing the pin from being further inserted into and exiting the pin hole 1141, serving as a guide and limit during installation and improving installation convenience. Specifically, the portion of the back plate 115 located at the second end of the pin hole 1141 can be bent to form a limiting flange 116. This limiting flange 116 can serve as a limit for the pin, and the limiting flange 116 can be an arc-shaped structure or a flat structure.

[0043] like Figure 3 As shown, in some embodiments of this utility model, the box body 10 is provided with at least one first bolt hole 115, the protective net 17 is provided with at least one second bolt hole 172 on the side away from the mating part 114, and the connecting member includes bolts, which are respectively inserted into the first bolt hole 115 and the second bolt hole 172.

[0044] It is understandable that the first bolt hole 115 can be set on the side opposite to the pin hole 1141 of the return air vent 113. The edge of the protective net 17 is provided with a second bolt hole 172. The part of the protective net 17 with the second bolt hole 172 can be widened to make the structure stronger and the bolt hole larger. One side of the return air vent 113 is connected to the housing 10 by connecting parts that pass through the first bolt hole 115 and the second bolt hole 172 in sequence, making the protective net 17 more reliably fixed. Based on the cooperation of the pin and the pin hole 1141 on one side, the reliability of the connection between the protective net 17 and the housing 10 is further improved.

[0045] like Figures 1 to 4 As shown, in some embodiments of this utility model, the plug-in part 171 and the connector are located on opposite sides of the protective net 17 along the length direction, and the length direction is perpendicular to the height direction of the box 10.

[0046] It is understandable that the plug-in part 171 and the connector can be respectively set on the left and right sides of the protective net 17, and the length direction can be the length direction of the box 10. This allows the installation process to be completed by first plugging the plug-in part 171 on one side of the protective net 17 into the box 10, then aligning the protective net 17 with the return air vent 113 and attaching the protective net 17 to the box 10, and finally fastening the other side of the protective net 17 to the box 10 through the connector. This makes assembly convenient and requires fewer screws.

[0047] In addition, the plug-in part 171 and the connector can also be set on the upper and lower sides of the protective net 17, that is, on both sides of the protective net 17 along the height direction of the housing 10. This allows the bottom end of the protective net 17 to be plugged into the mating part 114 on the housing 10 during installation, and the top end of the protective net 17 to be fastened to the return air vent 113 of the housing 10, and then fastened with the connector. This also achieves the effect of convenient assembly and requiring fewer screws.

[0048] like Figures 1 to 4 As shown, in some embodiments of this utility model, the protective net 17 includes a plurality of first support rods 173, the first support rods 173 extending along the length direction, and the plug-in portion 171 and the connector are respectively located at the two axial ends of the first support rods 173.

[0049] It is understandable that the protective net 17 is formed by multiple rods to form a mesh structure. Multiple first support rods 173 extend along the length of the box body 10. The left and right sides of the first support rods 173 are respectively provided with plug-in parts 171 and connectors. At the same time, multiple first support rods 173 can be connected by vertical connecting rods. The connecting rods can be U-shaped or straight and are connected to the first support rods 173 by welding.

[0050] like Figures 1 to 4 As shown, in some embodiments of this utility model, there are two first support rods 173, which are spaced apart along the height direction of the box 10. The protective net 17 also includes a plurality of second support rods 174, which extend along the length direction. The plurality of second support rods 174 are arranged between the two first support rods 173 and are spaced apart along the height direction of the box 10.

[0051] It is understandable that the first support rod 173 can be set on the upper and lower sides, and the second support rod 174 is set in the middle part. The second support rod 174 may not have the plug part 171 and the second bolt hole 172 to save costs. The first support rod 173 located at the edge is connected to the box body 10, so that the four corners of the protective net 17 are connected to the box body 10, which can improve the reliability of the connection.

[0052] like Figure 1 As shown, the second aspect of this utility model provides an outdoor unit 1, including a housing assembly, which is the same housing assembly proposed in the first aspect of this utility model.

[0053] The outdoor unit 1 proposed in the second aspect of this utility model can be an outdoor unit of an air conditioner, which has a protective net 17 that is easy to install and disassemble. One side of the protective net 17 is connected to the housing 10 through a connector, and the other side of the protective net 17 is slidably engaged with a support on the housing 10. The support supports the protective net 17, so that when installing the protective net 17, one side is aligned with the support and the other side is fastened by the connector to complete the installation. The installation is convenient and quick, and there is no need to use screws to fasten the two or four sides of the protective net 17.

[0054] The third aspect of this utility model provides a heating, ventilation and air conditioning (HVAC) device, including the outdoor unit 1 proposed in the second aspect of this utility model.

[0055] The heating and ventilation equipment proposed in the third aspect of this utility model can be an air conditioner. The outdoor unit 1 of the heating and ventilation equipment has a protective net 17 that is easy to install and disassemble. One side of the protective net 17 is connected to the housing 10 through a connector, and the other side of the protective net 17 is slidably engaged with the support part on the housing 10. The support part supports the protective net 17, so that when installing the protective net 17, one side is connected to the support part and the other side is fastened through the connector to complete the installation. The installation is convenient and quick, and there is no need to use screws to fasten the two or four sides of the protective net 17.

[0056] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
