Electric water heater

Abstract

The invention relates to an electric water heater comprising a displaying box with a display screen. A decoration plate is arranged on the exterior of the displaying box, the displaying face of the displaying screen faces the inner side of the decoration plate, and a film piece provided with a control circuit in a printed mode is arranged on the outer side of the decoration plate. The control circuit is connected with the displaying box through a connecting circuit penetrating out of the decoration plate. In the electric water heater, the control circuit is printed on the film piece for decoration plate injection molding, film pieces, springs or foam keys are omitted, the steps of manual pasting and the like are omitted, the cost is obviously reduced, and mounting is easier and rapider. The touch control flexibility is higher through the control circuit arranged between the outer surface of the decoration plate and the inner surface of the film piece, a hand of a user only needs to penetrate through the ultra-thin film piece, then touch control operation can be completed, experience is better, and the problems of time delaying and a small key effective area do not exist. The connecting circuit is connected with the displaying box in a contact piece mode, and thus circuit connecting is easier, tidier and more reliable.

Description

technical field [0001] The invention relates to an electric water heater, in particular to an electric water heater in which a control circuit and a decorative board are integrated. Background technique [0002] With the rapid development of modern science and technology and the improvement of people's material living standards, users have put forward higher requirements for the refinement of the appearance of water heaters. Through market research, it is found that many users report that the touch effect of water heaters on the market is not good, and they need to be pressed hard to be effective. Analysis of the reasons found that the main reason is that the key lines for controlling the local water heater are generally made on the display board or pasted on the inner surface of the outer decorative board, and there are problems such as touch control and cost. [0003] The touch problem is manifested in the fact that the fingers have to pass through the 2-3mm thick outer d...

AI Technical Summary

Problems solved by technology

[0003] The touch problem is manifested in the fact that the fingers have to pass through the 2-3mm thick outer decorative plate to touch the button spring or foam, and the touch sensitivity decreases, which will cause a delay in time. At the same time, it is affected by the size of the spring and foam. The effective area is small, and it is prone to non-action phenomenon, which brings bad experience to users

[0004] The cost problem is that the current solution needs to increase the price of button springs or foam. If the conductive film is attached to the inner surface of the base material of the outer decorative board, the diaphragm and labor costs will also need to be increased.
