Description

Technical Field

[0001] This utility model relates to the field of water heaters, and more particularly to a water heater housing. Background Technology

[0002] Currently, water heaters on the market consist of a base shell and a front panel. The front panel is installed at the open front of the base shell. The panel typically requires multiple screws to be fixed to the base shell, inevitably leaving the screws exposed and affecting the water heater's appearance. Furthermore, the use of multiple screws for installation means that aligning the screw holes during panel installation also impacts assembly efficiency.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned problems. We provide a water heater shell that improves the installation structure of the bottom shell and the panel, and simplifies the installation steps of the panel.

[0005] To achieve the above objectives, this utility model provides a water heater housing, comprising a bottom shell and a front panel. The front panel is mounted on an opening on the front side of the bottom shell. The inner wall of the bottom shell is provided with a positioning step that abuts against the back of the front panel. The lower end of the bottom shell is provided with a slot, and the upper end of the bottom shell is provided with a locking pin that can move up and down. The bottom of the front panel is provided with an insertion part that mates with the slot, and the top of the front panel is provided with a positioning hole into which the locking pin can be inserted. Near the upper end of the bottom shell is provided an elastic part that abuts against the back of the front panel. When the positioning step abuts against the front panel, the locking pin aligns with the positioning hole.

[0006] In one or more embodiments, the elastic part is a spring, a spring mounting cavity is provided in the bottom shell, one end of the spring is fixed to the spring mounting cavity, and the other end of the spring abuts against the back of the panel.

[0007] In one or more embodiments, the bottom shell is provided with two elastic portions, which are respectively located on the top two sides of the bottom shell.

[0008] In one or more embodiments, the positioning step is annular, and when the back of the panel abuts against the positioning step, the front side of the panel is flush with the front end face of the bottom shell.

[0009] In one or more embodiments, the slot is located at the middle of the lower end of the bottom shell, and the locking pin is located at the middle of the upper end of the bottom shell.

[0010] In one or more embodiments, the upper end of the bottom shell has a mounting hole through which a locking pin passes, and the locking pin has a handle portion that abuts against the upper end surface of the bottom shell.

[0011] Compared with the prior art, the advantages of this utility model are: the panel is connected to the slot at the bottom of the base shell through the insertion part at the bottom, and the panel is connected to the locking pin on the base shell through the positioning hole at the top, so that the panel is firmly installed on the base shell. The installation process of the panel does not use screws, which simplifies the installation process and improves the installation efficiency of the panel. Attached Figure Description

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] See appendix Figure 1-3 This application provides a water heater housing, which includes a bottom shell 1 and a panel 2. The panel 2 is mounted on an opening on the front side of the bottom shell 1. The inner wall of the bottom shell 1 is provided with a positioning step 3 that abuts against the back of the panel 2. The lower end of the bottom shell 1 is provided with a slot 4, and the upper end of the bottom shell 1 is provided with a locking pin 5 that can move up and down. The bottom of the panel 2 is provided with an insertion part 6 that mates with the slot 4. The top of the panel 2 is provided with a positioning hole into which the locking pin 5 can be inserted. The bottom shell 1 is provided with an elastic part 7 near the upper end that abuts against the back of the panel 2. When the positioning step 3 abuts against the panel 2, the locking pin 5 corresponds to the positioning hole. During installation, the insertion part 6 on the panel aligns with the slot 4 on the bottom shell 1. Pull out the locking pin 5, and then push the upper end of the panel 2 towards the bottom shell 1 so that the panel 2 contacts the positioning step. When in contact, the positioning hole aligns with the reduction 5. Then insert the locking pin into the positioning hole to complete the installation. When removing the panel 2, pull the locking pin 5 upward to disengage it from the positioning hole. The upper end of the panel opens outward under the elastic force of the elastic part. After the panel 2 opens, pull the panel out diagonally upward.

[0017] The elastic part 7 is a spring, which is a common elastic component on the market. It has good deformation recovery ability and elasticity. The bottom shell 1 is provided with a spring mounting cavity 8. One end of the spring is fixed in the spring mounting cavity 8, and the other end of the spring abuts against the back of the panel 2. When the panel abuts against the positioning step 3, the spring is in a compressed state.

[0018] The bottom shell 1 is provided with two elastic parts 7, which are respectively located on the top two sides of the bottom shell 1, so as to ensure that the panel 2 can be quickly pushed open after the locking pin 5 is disengaged from the mounting hole.

[0019] The positioning step 3 is ring-shaped. When the back of the panel 2 abuts against the positioning step 3, the front side of the panel 2 is flush with the front end of the bottom shell 1, so as to prevent the panel from protruding from the front end of the bottom shell.

[0020] The slot 4 is located at the middle of the lower end of the bottom shell 1, and the locking pin 5 is located at the middle of the upper end of the bottom shell 1 to facilitate alignment and installation. The placement of the slot and locking pin at the middle of the bottom shell 1 ensures the structural stability of the panel after installation.

[0021] The upper end of the bottom shell 1 has an installation hole for the locking pin 5 to pass through. The locking pin 5 has a handle 9 that abuts against the upper surface of the bottom shell 1. The user can easily pull out the locking pin 5 with the help of the handle 9.

[0022] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
