Description

Technical Field

[0001] This invention relates to the field of water heater technology, and in particular to an anti-electric shock wall cover structure and a water heater. Background Technology

[0002] Various control labels and switches on a water heater are usually located on the control panel. The control panel is installed on the outer shell of the water heater tank through an anti-electric shock wall cover. The control panel and the anti-electric shock wall cover are usually fastened with screws or fixed with clips.

[0003] Figure 1 An exploded view of the installation of an anti-electric shock wall cover and control panel in the prior art, such as... Figure 1 As shown, the display panel 30' is first installed with the display panel back cover 40', then the assembly of the display panel 30' and the display panel back cover 40' is installed on the control panel 20', and then the control panel 20' is installed on the anti-electric shock wall cover 10'. The display panel back cover 40' is set in and connected to the pre-reserved mounting slot 50' in the anti-electric shock wall cover 10'. The purpose of setting the display panel back cover 40' is to protect the internal display panel 30' and to provide waterproofing from the rear.

[0004] In the existing technology, the display panel back cover 40' needs to be designed and manufactured separately. The corresponding control panel 20' and anti-electric shock wall cover 10' need to be designed with mounting structures that match the display panel back cover 40', which increases production costs and assembly processes. Moisture inside the anti-electric shock wall cover 10' can easily enter the display panel 30' through the mounting groove 50', affecting the waterproof effect. Summary of the Invention

[0005] To address the aforementioned problems, one objective of this invention is to propose an anti-electric shock wall cover structure that is simple in structure and has good waterproof performance.

[0006] Another objective of this invention is to provide a water heater that employs the aforementioned anti-electric shock wall cover structure, which, compared to the prior art, saves costs because it eliminates the need for a display panel back cover.

[0007] The present invention adopts the following technical solution:

[0008] An anti-electric shock wall cover structure includes a rear wall and a top wall, a bottom wall and two side walls protruding from the edge of the rear wall. The rear wall, top wall, bottom wall and side walls enclose an installation space. Water-blocking ribs are protruding on the top wall and side walls, and overflow holes are provided on the bottom wall.

[0009] As a preferred embodiment of the present invention, the rear wall is set at an angle to the vertical direction.

[0010] As a preferred embodiment of the present invention, the water-blocking ribs protruding on the top wall and the water-blocking ribs protruding on the side wall are connected to form an integral structure.

[0011] As a preferred embodiment of the present invention, the water-blocking ribs protruding from the top wall are arranged at an angle to the top wall.

[0012] As a preferred embodiment of the present invention, multiple slots are provided at intervals on the top wall and / or bottom wall and / or side wall.

[0013] As a preferred embodiment of the present invention, multiple reinforcing ribs are provided at intervals at the connection between the rear wall and the bottom wall and / or the connection between the rear wall and the top wall and / or the connection between the rear wall and / or the side wall.

[0014] As a preferred embodiment of the present invention, through holes for passing wires are provided on the rear wall and / or top wall and / or bottom wall and / or side wall.

[0015] As a preferred embodiment of the present invention, the anti-electric shock wall cover structure is integrally formed.

[0016] A water heater includes a control panel and a display panel, employing the aforementioned anti-electric shock wall cover structure. The display panel is installed within the installation space, and the control panel is snapped into the anti-electric shock wall cover structure.

[0017] As a preferred embodiment of the present invention, the control panel is located at the center of the anti-electric shock wall cover structure.

[0018] The beneficial effects of this invention are as follows:

[0019] This invention proposes an anti-electric shock wall cover structure. By setting a rear wall and a top wall, a bottom wall, and two side walls protruding from the edge of the rear wall, the rear wall, top wall, bottom wall, and side walls can enclose an installation space to waterproof the components in the installation space. At the same time, water-blocking ribs are protruding on the top wall and side walls, and overflow holes are provided on the bottom wall. When the anti-electric shock wall cover structure is installed in conjunction with other structures, liquid entering from the top wall and side walls is guided by the water-blocking ribs to the overflow holes on the bottom wall, further ensuring the waterproof effect and making the structure simpler.

[0020] This invention proposes a water heater that employs the aforementioned anti-electric shock wall cover structure. The display panel is installed within the installation space, and the control panel is directly snapped onto the anti-electric shock wall cover structure, thus enabling the control panel to be mounted on the anti-electric shock wall cover structure. Compared with existing technologies, there is no need for a rear shell for the display panel, saving costs. Attached Figure Description

[0031] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] Figure 2 This is an exploded view of the water heater provided by the present invention, such as... Figure 2 As shown, the water heater mainly includes an anti-electric shock wall cover 10, a control panel 20, and a display panel 30. The display panel 30 is installed on the control panel 20, and the control panel 20 is then installed on the anti-electric shock wall cover 10. Compared with the prior art, there is no need to set a back cover for the display panel, which saves costs.

[0035] Furthermore, the anti-electric shock cover 10 includes a rear wall 1 and a top wall 2, a bottom wall 3, and two side walls 4 protruding from the edge of the rear wall 1. The rear wall 1, top wall 2, bottom wall 3, and side walls 4 enclose an installation space for accommodating the display panel 30. Specifically, the entire anti-electric shock cover 10 is integrally molded by injection molding. Both the top wall 2 and side walls 4 are provided with water-retaining ribs 5, and the bottom wall 3 is provided with an overflow hole 6. When the anti-electric shock cover 10 is installed in conjunction with the control panel 20, liquid entering from the top wall 2 and side walls 4 is guided to the bottom wall 3 by the water-retaining ribs 5 and flows out through the overflow hole 6, further ensuring the waterproof effect and simplifying the structure.

[0036] Specifically, from Figure 2 As can be seen, one side of the anti-electric shock wall cover 10 is an open frame structure, formed by a rear wall 1 and a top wall 2, a bottom wall 3, and two side walls 4 protruding from the edge of the rear wall 1. The other side is an arc-shaped mounting part, which is used for mounting with the water heater's cylinder. This mounting part includes a water inlet 101 for accommodating the water inlet pipe and a water outlet 102 for accommodating the water outlet pipe. It is foreseeable that when the water heater is operating, water may enter through the water inlet 101 and water outlet 102 due to pipe damage. Since the rear wall 1 is a single planar structure, it can prevent water from the water inlet 101 and water outlet 102 from entering the display panel 30. Figure 3 This is a schematic diagram of the anti-electric shock wall cover and control panel provided by the present invention. Figure 3 As can be seen, the rear wall 1 is set at an angle to the vertical direction, such as... Figure 3The included angle α. Since the water heater is usually installed at a height higher than the user's head, and since the rear wall 1 is set with an inclined structure, the control panel 20 is also inclined, with the control panel 20 tilted towards the user for easy operation.

[0037] Figure 4 This is a structural schematic diagram of the anti-electric shock wall cover provided by the present invention, as shown below. Figure 4 As shown, the water-blocking ribs 5 protruding on the top wall 2 and the water-blocking ribs 5 protruding on the side wall 4 are connected to form an integral structure, that is, the water-blocking ribs 5 are connected to form a "U-shaped" structure, with the opening facing downward; an overflow hole 6 is provided on the bottom wall 3.

[0038] It is expected that when the control panel 20 is installed together with the anti-electric wall cover 10, there will be gaps in the installation. Liquid may enter the interior of the anti-electric wall cover 10 through the gaps. However, by setting the water-blocking ribs 5, the liquid entering from the gaps at the top wall 2 and the side wall 4 is guided by the water-blocking ribs 5 to the overflow hole 6 on the bottom wall 3 and discharged from the anti-electric wall cover 10, without affecting the display panel 30.

[0039] Furthermore, Figure 5 yes Figure 3 The enlarged view at point A shows that the water-retaining rib 5 protruding from the top wall 2 is angled to the top wall 2. This allows the water-retaining rib 5 to catch liquid entering from the gap in the top wall 2, preventing liquid from overflowing from the rib 5. The liquid is better blocked by the water-retaining rib 5 and guided to the overflow hole 6 on the bottom wall 3. This invention does not limit the specific shape, inclination angle, or installation position of the water-retaining rib 5. Any structure that can prevent liquid from overflowing from the water-retaining rib 5 and guide it to the overflow hole 6 for discharge is within the protection scope of this invention.

[0040] Furthermore, to ensure better installation of the anti-electric shock wall cover 10 with the control panel 20, bolt connection or other connection methods can be selected. In this embodiment, a snap-fit ​​connection is preferred. Specifically, as shown... Figure 2 As shown, multiple slots 7 are spaced apart on both the top wall 2 and the bottom wall 3, and a locking protrusion 201 is provided on the control panel 20. The locking protrusion 201 can be engaged and fixed with the slots 7. It can be expected that the present invention does not specifically limit the position and number of slots 7. The slots 7 can be provided on the top wall 2 and / or the bottom wall 3 and / or the side wall 4. In this embodiment, since the top wall 2 and the bottom wall 3 are relatively long, it is preferable to provide multiple slots 7 on the top wall 2 and the bottom wall 3.

[0041] Furthermore, multiple reinforcing ribs 8 are provided at intervals at the connection between the rear wall 1 and the bottom wall 3, and / or the connection between the rear wall 1 and the top wall 2, and / or the connection between the rear wall 1 and / or the side wall 4, to enhance the structural strength of the connection. This embodiment only shows that multiple reinforcing ribs 8 are provided at intervals at the connection between the rear wall 1 and the bottom wall 3 to ensure structural strength.

[0042] To allow the wires of the display panel 30 to connect to the outside, a through hole 9 is provided on the rear wall 1 for wire passage. The wires of the display panel 30 are neatly arranged and pass through the through hole 9. It can be expected that a sealing ring or other structure is also provided around the through hole 9 to achieve a waterproof effect. In this embodiment, the specific location of the through hole 9 is not limited. The through hole 9 can be opened on the rear wall 1, or it can be opened in other locations such as the top wall 2, bottom wall 3, and side wall 4. No specific limitation is made here.

[0043] Furthermore, since the control panel 20 is installed on the anti-electric shock wall cover 10, in order to prevent the control panel 20 or the anti-electric shock wall cover 10 from deforming due to internal or external reasons, which would greatly affect the structural strength of the entire water heater, it is preferable to set the control panel 20 at the center of the anti-electric shock wall cover 10.

[0044] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
