[0032] Existing heat pump mainframe chassis are usually equipped with access panels. In order to take into account both aesthetics and convenient disassembly and maintenance, existing access panels are usually equipped with buckles, and the access panels are fixed by buckling with the structures on the chassis corresponding to the two sides of the access panels. In actual operation, the assembly of the whole machine is affected by the processing errors of the various components of the chassis, or by the errors of manual assembly, or by the unreasonable design and fixing method. There are usually problems of excessive gaps and uneven gaps between the buckles of the access panels and the connected structures after assembly, which leads to fluctuations in the access panel during transportation, wear of plastic parts caused by friction between the access panel and plastic parts, and noise caused by vibration during unit operation, which affects the quality of the product.

[0033] like Figure 1-7 As shown, this embodiment provides a heat pump chassis, including:

[0034] The access panel 1 comprises an access panel body 11, a first buckle 12 and a second buckle 13, wherein the access panel body 11 has a first connecting side and a second connecting side opposite to each other, the first buckle 12 is connected to the first connecting side, and the second buckle 13 is connected to the second connecting side;

[0035] A first connecting plate, a first card slot 21 is provided on one side connected to the inspection plate 1, the first card slot 21 is of a gradually tapered design, the wide end of the first card slot 21 allows the first clip 12 to be inserted, and the narrow end of the first card slot 21 clamps the first clip 12;

[0036] The second connecting plate is provided with a second slot 31 on one side connected to the inspection plate 1 . The second slot 31 is designed with a gradually tapered opening. The wide end of the second slot 31 allows the second buckle 13 to be inserted, and the narrow end of the second slot 31 clamps the second buckle 13 .

[0037] Specifically, the heat pump chassis includes a chassis bottom plate 5, a chassis top cover 6 and a surrounding wall plate connected between the chassis bottom plate 5 and the chassis top cover 6. The surrounding wall plate is generally composed of multiple plates connected together, and the inspection panel 1 is one of the plates. When the heat pump unit fails, the inspection panel 1 can be removed separately to inspect the internal unit.

[0038] The first connecting plate and the second connecting plate are two plates in the surrounding wall plate respectively connected to the two sides of the inspection plate 1. The first connecting plate and the second connecting plate can provide stable support for the inspection plate 1 to ensure the reliability of the installation of the inspection plate 1.

[0039] In the present embodiment, the first buckle 12 and the second buckle 13 are respectively provided on both sides of the access panel 1, which can be engaged and fixed with the first slot 21 and the second slot 31 provided on the first connecting plate and the second connecting plate on both sides to realize the installation of the access panel 1. Importantly, the first slot 21 and the second slot 31 of the present embodiment are both of a gradual shrinking design. During installation, the first buckle 12 and the second buckle 13 can be inserted from the wider end of the first slot 21 and the second slot 31, respectively, and then the entire access panel 1 is pushed to make the first buckle 12 and the second buckle 13 respectively snap into the narrower part of the first slot 21 and the second slot 31, and the first buckle 12 and the second buckle 13 are clamped by the narrowed slot, thereby avoiding the gap between the buckle and the slot after installation, improving the tightness of the access panel 1 after installation, thereby avoiding the problems of plastic parts wear and noise caused by the shaking of the access panel 1 during transportation and use.

[0040] It can be understood that, in order to facilitate installation and ensure the stability of the access panel 1 after installation, the wider end of the first slot 21 and the first buckle 12 are clearance fit, and the first buckle 12 can be easily passed through the first slot 21 for disassembly and assembly; the narrower end of the first slot 21 and the first buckle 12 are interference fit, and the first buckle 12 can be tightly clamped after installation. Similarly, the wider end of the second slot 31 and the second buckle 13 are clearance fit, and the second buckle 13 can be easily passed through the second slot 31 for disassembly and assembly; the narrower end of the second slot 31 and the second buckle 13 are interference fit, and the second buckle 13 can be tightly clamped after installation.

[0041] In one embodiment, referring to Figure 3The first buckle 12 has a first hook 121, and the second buckle 13 has a second hook 131. The first hook 121 is buckled on the inner side of the first connecting plate, and the second hook 131 is buckled on the inner side of the second connecting plate.

[0042] The first clip 12 and the second clip 13 are respectively provided with a first hook 121 and a second hook 131. After the inspection panel 1 is installed in place, the first hook 121 and the second hook 131 can just buckle onto the inner sides of the first connecting plate and the second connecting plate respectively to prevent the installed inspection panel 1 from being separated from between the first connecting plate and the second connecting plate, thereby reinforcing the installation of the inspection panel 1.

[0043] In one embodiment, referring to Figure 5 and Figure 6 The first card slot 21 and the second card slot 31 are gradually contracted from bottom to top, and the first hook 121 and the second hook 131 are extended from bottom to top, so that the installation direction of the access panel 1 is to push up and buckle from bottom to top.

[0044] The first card slot 21 and the second card slot 31 are both configured to be narrow at the top and wide at the bottom. During installation, the first clip 12 and the second clip 13 can be inserted into the wider sections of the first card slot 21 and the second card slot 31, respectively. Then, the entire access panel 1 is pushed upward, so that the first clip 12 and the second clip 13 are simultaneously clamped by the narrower sections of the first card slot 21 and the second card slot 31, and at the same time, the first hook 121 and the second hook 131 are respectively buckled to the inner sides of the first connecting plate and the second connecting plate. In one embodiment, a positioning hole 1141 is provided at the lower end of the access panel body 11, and the connecting nail locks the access panel body 11 to the chassis bottom plate 5 through the positioning hole 1141 to limit the downward movement of the access panel 1.

[0045] A positioning hole 1141 is provided at the lower end of the access panel body 11. After the access panel 1 is mounted in place, a connecting nail is passed through the positioning hole 1141 and then locked to the chassis bottom plate 5, which can limit the up and down movement of the access panel 1, thereby limiting the first buckle 12 and the second buckle 13 from being disengaged, and effectively strengthening the installation of the access panel 1. The connecting nail is preferably a detachable screw, and a threaded hole is correspondingly provided on the chassis bottom plate 5.

[0046] In one embodiment, the inspection panel body 11 includes a main panel body 111 and an inner folding plate 114 connected to the lower edge of the main panel body 111 , the inner folding plate 114 is L-shaped, and the positioning hole 1141 is provided on the inner folding plate 114 .

[0047] An inwardly collapsed inner folding plate 114 is provided on the bottom side of the inspection panel body 11, and a positioning hole 1141 is provided on the inner folding plate 114. The connecting nails after installation will not protrude from the outer surface of the main panel body 111. Therefore, this arrangement can hide the connecting nails to a certain extent.

[0048] In one embodiment, referring to Figure 7 The first clip 12 extends in a first direction relative to the access panel body 11, and the second clip 13 extends in a second direction relative to the access panel body 11. There is an angle between the first direction and the second direction, and the angle ranges from 70° to 90°.

[0049] With such a configuration, after the first buckle 12 and the second buckle 13 are engaged, they can respectively restrict the movement of the access panel 1 from different degrees of freedom. Specifically, after being engaged, the first buckle 12 can restrict the reciprocating movement of the access panel 1 in the first direction, and the second buckle 13 can restrict the reciprocating movement of the access panel 1 in the second direction. Moreover, the angle between the first direction and the second direction is in the range of 70° to 90°. The combination of the two can just restrict the movement of the access panel 1 in all directions parallel to the ground. Therefore, this structure can effectively improve the stability of the access panel 1 clamping.

[0050] In one embodiment, the first direction is perpendicular to the access panel body 11 , and the angle between the second direction and the access panel body 11 is 3° to 10°.

[0051] Reference Figure 7 , the angles between the first direction and the second direction and the access panel body 11 are based on the plane where the outer surface of the access panel body 11 is located, the angle between the second direction and the access panel body 11 is a, and the range of ∠a is 3° to 10°, which can facilitate the assembly of the access panel 1. Specifically, during assembly, the second buckle 12 can be aligned with the second card slot 31 and inserted while keeping the access panel 1 tilted, so that the first buckle 12 and the first connecting plate are kept at a distance to avoid interference between the first connecting plate and the first buckle 12, and then the side of the access panel 1 with the first buckle 12 is pushed toward the first connecting plate, so that the first buckle 12 is inserted into the first card slot 21, and then the entire access panel 1 is pushed up and clamped. Preferably, ∠a is 4°, 5° or 6°.

[0052] In one embodiment, the inspection panel body 11 includes a main board body 111 and a first folded edge 112 and a second folded edge 113 that are vertically bent to the same side relative to the main board body 111, the first folded edge 112 is located on the first connection side, the second folded edge 113 is located on the second connection side, the first buckle 12 is connected to the first folded edge 112, and the second buckle 13 is connected to the second folded edge 113.

[0053] In the structure of the access panel body 11, the first folded edge 112 and the second folded edge 113 are respectively bent on both sides of the main board body 111, which can effectively improve the anti-bending and anti-deformation capabilities of the access panel body 11 while keeping the main board body 111 itself thin, thereby improving the reliability of the access panel 1. Therefore, the access panel 1 of this solution has the advantages of less consumables, light weight, and good reliability.

[0054] In one embodiment, referring to Figure 5 The first connecting plate is a water inlet plate 2, and a connecting portion 22 matching the first folded edge 112 is provided on one side of the first connecting plate connected to the inspection plate 1, and the first card slot 21 is provided on the connecting portion 22, and a receiving recess is provided on the side of the connecting portion 22 away from the center of the heat pump chassis, and the first folded edge 112 is embedded in the receiving recess so that the first buckle 12 can be inserted into the first card slot 21, and the outer surface of the inspection plate body 11 is flush with the outer surface of the first connecting plate.

[0055] A connecting portion 22 is provided on the side of the water inlet plate 2, which is convenient for setting the first slot 21 to engage with the first buckle 12, and can accommodate the thickness of the inspection plate 1, so that the outer surface of the inspection plate 1 after installation is flush with the outer surface of the water inlet plate 2, thereby optimizing the appearance of the heat pump chassis.

[0056] In one embodiment, it also includes a front panel 4, which is connected to the second connection side; the second connection plate is a support column 3 supported between the chassis bottom plate 5 and the chassis top cover 6, and the second connection plate is hidden in the inspection panel 1 and the front panel 4.

[0057] The support column 3 is arranged inside the connection between the front panel 3 and the access panel 1, which can provide reliable support for the top chassis cover 6. Under the condition of ensuring the reliability of the chassis cover 6, the front panel 3 can directly use a lower-cost injection molded part to achieve the effect of reducing costs. The support column 3 is a sheet metal part with reliable strength. The support column 1 is used as the second connecting plate for clamping the access panel 1 to ensure the reliability of the installation of the access panel 1. The support column 3 is hidden inside the access panel 1 and the front panel 4, which can ensure the flatness of the appearance of the heat pump chassis.

[0058] In another embodiment, the second connecting plate is a front panel 4, and a side of the front panel 4 connected to the inspection panel 1 is provided with a connecting fold extending inwardly perpendicular to the main board body 111, and the second buckle 13 is arranged on the connecting fold.

[0059] By directly using the front panel 4 as the second connecting plate for supporting the inspection panel 1 , the number of structural parts of the heat pump chassis can be reduced, and the structure of the heat pump chassis can be simplified.

[0060] In the description of this article, it should be understood that the terms "upper", "lower", "left", "right", etc., and other directions or positional relationships are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of this application.
