Description

Technical Field

[0001] The invention relates to the field of heat pumps, in particular to a chassis of an outdoor unit. Background Art

[0002] In the existing heat pump outdoor unit, some chassis shells are made of plastic material according to user needs. However, when encountering a relatively large heat pump unit, due to the large size of the chassis, the area of ​​the front panel and the rear panel of the chassis is too large. After injection molding, the large area of ​​the plastic panel is easy to cause the panel to bend forward and backward, resulting in the problem of poor assembly of the chassis. In addition, during production demolding, the front and rear panels are demolded to the outside, and this deformation will cause the front and rear panels to bulge, thereby affecting the assembly accuracy and appearance smoothness of the front and rear panels and the holes of the two side panels, resulting in poor assembly and unsightly appearance. Summary of the invention

[0003] Based on this, the object of the present invention is to provide an outdoor unit chassis, which has the advantages of easy assembly, good installation effect, smooth and beautiful appearance.

[0004] The present invention is achieved through the following technical solutions.

[0005] An outdoor unit chassis comprises a front panel and a rear panel arranged opposite to each other, wherein the front panel and the rear panel both comprise a panel body, and is characterized in that the panel body of at least one of the front panel and the rear panel is a curved panel, and the curved panel is arranged to protrude into the chassis.

[0006] The present invention sets the front panel and the rear panel to have a structure with a proper curvature toward the inside of the chassis to solve the problems of poor assembly and appearance caused by deformation of the panel after injection molding and during demoulding.

[0007] Furthermore, the upper edge and the lower edge of the arc panel are both arcs with the same structure and are roughly in the shape of "︵".

[0008] Furthermore, the upper edges of the front panel and the rear panel are intermittently provided with a plurality of grooves, the openings of the grooves facing the inner side of the chassis. The provision of the grooves facilitates the front panel and the rear panel to bend in an arc shape, and facilitates the production of the arc panel.

[0009] Furthermore, the width of the groove is 1cm-2cm.

[0010] Furthermore, the chassis further comprises a left side panel and a right side panel which are arranged opposite to each other, the left and right ends of the front panel and the rear panel are both provided with buckles, and the left and right side panels are provided with transverse buckle holes corresponding to the buckles, and the width of the buckle holes gradually increases from one end to the other end. The buckle holes are trapezoidal holes or holes formed by a combination of a large diameter arc and a small diameter arc. Through the cooperation between the buckles and the transverse buckle holes, the front panel, the rear panel and the side panel are easily and stably installed, and deformation of the panel during installation is avoided.

[0011] Furthermore, the front panel and the rear panel are both provided with a mounting hole 1, and the left panel and the right panel are both provided with a mounting hole 2 corresponding to the mounting hole 1, and the mounting hole 1 is threadedly connected with the corresponding mounting hole 2 by a fastener. The fastener may be a screw or a bolt. By further fastening with screws on the basis of the buckle and the buckle hole installation, the chassis is made more stable and strong. Furthermore, the mounting hole 1 is a countersunk hole. The setting of the countersunk hole improves the aesthetics of the chassis and also prevents the fastener from loosening due to external forces.

[0012] Furthermore, a plurality of positioning posts are arranged at intervals on the inner bottom of the front side panel and the rear panel, and mounting holes corresponding to the positioning posts are arranged on the bottom plate. Through the cooperation between the positioning posts and the positioning holes, convenient and stable installation of the front and rear panels and the bottom plate is achieved. Further, the positioning post includes a rod-shaped fixing member 1, one end of which is fixedly connected to the front panel or the rear panel, and a plurality of radially protruding plates are arranged on the outer circumferential surface of the fixing member 1, and the radial width of the plates gradually decreases from one end of the fixing member 1 to the end away from the rear panel. The positioning post also includes a fixing member 2 with an arc-shaped surface, the radial width of the fixing member 2 is greater than the radial width of the fixing member 1, and the other end of the fixing member 1 is fixedly connected to the fixing member 2. Through the positioning post structure of the above structure, the positioning post is inserted into the corresponding mounting hole and snapped into the hole to conveniently achieve a stable connection.

[0013] In the present invention, the panel curvature is set in advance, such as when the panel mold is designed, so that the panel has a certain curvature in advance, so as to avoid the deformation generated during the panel manufacturing process affecting the subsequent assembly and use of the panel.

DETAILED DESCRIPTION

[0027] The present invention discloses an outdoor unit chassis, wherein a plurality of components (not shown in the figure) such as a heat exchanger, a compressor, a fan, and a motor are installed inside the chassis.

[0028] exist Figure 1-3In the embodiment, the chassis includes a front panel 1 located in the front of the chassis, a rear panel 2 located in the rear, a left side panel 7 located on the left, a right side panel 3 located on the right, a top panel 4 located at the top, and a bottom panel 14 located at the bottom. The front panel 1, the rear panel 2, the left side panel 7, the right side panel 3, the top panel 4, and the bottom panel 14 together form an inner cavity of the chassis. Among them, the left side panel 7 and the right side panel 3 are flat. The front panel 1 includes a panel body 1-1 and side panels 1-2 on both sides. The panel body 1-1 is connected to the side panels 1-2 on both sides in an arc shape. The panel body 1-1 of the front panel 1 is an arc panel with a certain curvature. It can be seen from the figure that the curvature is relatively small. The panel body 1-1 protrudes into the inside of the chassis. The upper edge and the lower edge of the panel body 1-1 are both arcs with the same structure and the shape of the top view structure is roughly "︵". The left edge and the right edge of the panel body of the front panel 1 are both straight and vertically arranged. Further, the rear panel 2 has the same structural setting as the front panel 1 mentioned above. In this scheme, the curvature of the front panel 1 and the rear panel 2 is specially designed during the panel manufacturing process, such as when designing the panel mold, and the required panel curvature is processed through the processing technology.

[0029] exist Figure 3-4 In the figure, a plurality of grooves 8 are arranged on the upper edges of the front panel 1 and the rear panel 2. The grooves 8 are arranged at intervals, and one side of the grooves 8 is opened toward the interior of the chassis, that is, the side of the grooves 8 close to the interior of the chassis passes through the side wall of the panel, and the width of the grooves 8 is preferably set to 1cm-2cm.

[0030] exist Figure 3-7 In the figure, buckles 10 are provided at the left and right ends of the front panel 1 and the rear panel 2, and protrusions are provided at the ends of the buckles 10. Correspondingly, buckle holes 9 are provided at the corresponding positions of the left side panel 7 and the right side panel 3. It can be seen from the figure that the buckle holes 9 are arranged horizontally, and the width of the buckle holes 9 is wide at the outer ends of the left side panel 7 and the right side panel 3 and narrow at the inner ends. The shape of the buckle hole 9 can be a roughly trapezoidal hole, or it can be composed of two arc holes with a large arc diameter at the outer ends of the left side panel 7 and the right side panel 3 and a small arc diameter at the inner ends. During installation, the buckle 10 is pushed from the side with a larger width of the buckle hole 9 and gradually moves to the side with a smaller width until it is locked. At this time, the protrusions on the buckle 10 abut against the surfaces of the left side panel 7 and the right side panel 3 to form a fixation. This installation method can limit the up and down movement of the front panel 1 and the rear panel 2 and form a pre-installation. At the same time, the front panel 1 and the rear panel 2 are both provided with a mounting hole 1, and the left panel 7 and the right panel 3 are both provided with a mounting hole 2 corresponding to the mounting hole 1, and the mounting hole 1 is threadedly connected with the corresponding mounting hole 2 by a fastener, wherein the mounting hole 1 is a countersunk hole. During installation, after the pre-installation is formed, the front panel 1, the rear panel 2 and the left panel 7 and the right panel 3 are threadedly connected by the fastener, so as to form a stable installation.

[0031] exist Figure 8-10In the embodiment, a plurality of spaced positioning posts are provided at the inner bottom of the front side panel 1 and the rear panel 2, and a plurality of mounting holes corresponding to the positioning posts are provided on the bottom plate 14, and the front panel, the rear panel and the bottom plate are quickly installed by using the positioning posts and the mounting holes. The positioning posts include a rod-shaped fixing member 11, one end of which is fixedly connected to the front panel 1 and the rear panel 2, and a plurality of radially protruding plates 12 are provided on the outer circumferential surface of the fixing member 11, and the radial width of the plates 12 gradually decreases from one end of the fixing member 11 to the end away from the front panel 1 and the rear panel 2. In order to improve the stability of the installation, the positioning posts also include a fixing member 2 13 with an arc-shaped surface, the fixing member 11 is fixedly connected to the fixing member 2 13, and the radial width of the fixing member 2 13 is greater than the radial width of the fixing member 11.

[0032] exist Figure 1-2 In 11, a plurality of first ridges 5 are protrudingly provided on the upper surface of the top plate 4, and grooves 6 are formed between the first ridges 5. A plurality of second ridges 15 are also protrudingly provided on the bottom surface of the top plate 4. The first ridges 5 and the second ridges 15 are arranged at intervals and extend from one end of the top plate 4 to the other end. In the figure, the extension directions of the first ridges 5 and the second ridges 15 are the same, but the extension directions of the two can also be set to be different. In addition, the first ridges 5 are arranged in parallel, and the second ridges 15 are also arranged in parallel. The first ridges 5 and the second ridges 15 can be straight or wavy. Providing ridges on the surface of the top plate 4 is conducive to heat dissipation and increasing the load-bearing strength of the top plate.

[0033] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and the present invention is also intended to include these modifications and modifications.
