Description

Technical Field

[0001] The utility model relates to the field of electric water heaters, in particular to an electric water heater equipped with a panel assembly with a screw hiding function. Background Art

[0002] With the continuous improvement of people's living standards and the continuous expansion of the electric water heater market, consumers are pursuing higher and higher quality for electric water heaters. In terms of the protection of live parts of electric water heaters, the "General Requirements for Safety Part 1 of Household and Similar Electrical Appliances" stipulates the protection requirements for touching live parts, that is, it is not allowed to touch live parts without the help of tools. This means that, for example, the panel assembly is purely detachable by buckles, which does not meet the safety requirements. Therefore, at least one screw needs to be added to fix the structure. In this regard, most manufacturers usually fix the screws directly on the appearance surface, and then cover it by adding screw covers, patches, etc. This not only affects the appearance of the product, reduces consumers' purchasing desire, but also leads to poor waterproof effect. Specifically, adding a screw cover to the screw on the appearance surface will still destroy the integrity of the appearance of the electric water heater like a patch; using patches to hide the screws on the appearance surface, although it solves the aesthetic problem, it can only be used on specific products with patches, which has great limitations and brings another problem, that is, it is very inconvenient to repair, and the patch needs to be torn off for repair, and a new patch needs to be replaced after repair. The above methods are the result of mutual compromise, and do not fundamentally solve this problem. Moreover, this compromise has affected product quality to a certain extent and reduced consumers' purchasing desire.

[0003] In order to comply with safety regulations and solve various problems caused by exposed screws, it is urgent to develop a panel assembly for electric water heaters that is both beautiful, waterproof and easy to maintain, so as to improve product quality and increase consumers' purchasing desire.

[0004] For example, the Chinese invention application with application publication number CN116465090A and titled electric water heater discloses: For the panel assembly 4, it includes: a front panel 41, the upper part of the front panel 41 is provided with a card slot 411, and the bottom of the front panel 41 is provided with a second mounting hole 412; a control panel 42, the control panel 42 is arranged on the front panel 41; a decorative panel 43, the bottom of the decorative panel 43 is provided with a card connection portion 431, the upper part of the decorative panel 43 is provided with an auxiliary plug-in portion 432, and the card connection portion 431 is carded in the card slot 41. The front part of the housing 1 is provided with a limiting hole 14. In the actual assembly process, the control panel 42 is assembled with the front panel 41, and the decorative panel 43 is also pre-assembled on the front panel 41, so that the front panel 41, the control panel 42 and the decorative panel 43 form a modular structure, and then the panel assembly 4 is assembled to the housing 1 as a whole. Among them, the decorative plate 43 is clamped together by the clamping part 431 and the clamping slot 411, so there is no need to connect and fix the two by screws to reduce the use of screws. In addition, the housing 1 is provided with a corresponding limiting hole 14. When assembling the panel assembly 4, the auxiliary plug-in part 432 of the decorative plate 43 is inserted into the limiting hole 14 to achieve the top limit, and then the screw is inserted into the second mounting hole 412 to fix it on the housing to achieve the bottom fixation, thereby fixing the panel assembly 4 on the housing 1. Although the invention application adopts the clamping method in many places to reduce the use of screws, the bottom of the panel assembly 4 cannot avoid being installed on the housing 1 by screws, that is, the appearance is still unsightly and the waterproof effect is poor.
