an electric water heater

Abstract

The invention relates to an electric water heater. The electric water heater includes a display box with a display screen. A decorative board is arranged outside the display box. The display surface of the display screen faces the inner side of the decorative board. The diaphragm of the circuit, the control circuit is connected with the display box through the connecting circuit passing through the decorative board. In the present invention, the control circuit is printed on the diaphragm used for injection molding the decorative board, which saves the diaphragm, spring or foam button, and omits steps such as manual sticking. The cost optimization is obvious, and the installation is simpler and faster. The control circuit arranged between the outer surface of the decorative board and the inner surface of the diaphragm makes the touch sensitivity higher, and the user's hand only needs to pass through the ultra-thin diaphragm to complete the touch operation, and the experience is better and there is no time. Latency and small key active area issues. The connection circuit is connected with the display box in the form of a contact piece, so that the connection of the circuit is simpler, more regular 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.
