Abstract

A liquid heater comprises a body and a display portion. A photosensitive component is arranged on the body and used for adjusting brightness of the display portion. The photosensitive component consists of a photosensitive sensor, a single chip microcomputer circuit is disposed at a position, which corresponds to that of the photosensitive sensor, inside the body, and a brightness signal input circuit of the photosensitive sensor is electrically connected with the single chip microcomputer circuit. The liquid heater has the advantages of simple and reasonable structure, environmental protection, energy conservation, simplicity and convenience in operation and long service life, brightness of ambient light is induced by the additionally arranged photosensitive sensor, brightness signals are fed back to a single chip microcomputer for processing, the brightness of a liquid crystal display screen on the outer surface of the liquid heater is automatically adjusted, the purposes that the brightness of the display screen is increased in daylight or when the ambient light is strong and the brightness of the display screen is decreased at night or when the ambient light is dark are realized, and the problems that a user cannot see displayed content in daylight when light is strong and a displayed portion is dazzling to hurt eyes at night or when the ambient light is dark are solved.

Description

Liquid heater

Technical field

The utility model relates to a kind of liquid heater.

Background technology

Along with the increasingly extensive application of liquid heater, the household electrical appliances of band function display screen become a kind of trend, and it is attractive in appearance that this both can increase product, can improve product specification again.But the display screen of liquid heater can't be regulated display brightness according to ambient brightness in the market, because when the light of daytime or environment is too strong, may occur seeing that the content on the display screen is just not obvious, when evening or light are too dark, may occur seeing that the content on the display screen can be dazzling especially.Therefore, be necessary to be further improved and perfect.

The utility model content

The purpose of this utility model aims to provide a kind of simple and reasonable, low cost of manufacture and the good liquid heater of display effect, to overcome weak point of the prior art.

A kind of liquid heater by this purpose design comprises main structure body and display unit, and its architectural feature is that described main body is provided with photosensitive-member, to regulate the brightness of display unit.

Described photosensitive-member comprises light sensor, and the position of the corresponding light sensor of body interior is provided with single chip circuit; The luminance signal input circuit of this light sensor is electrically connected with single chip circuit.

Described light sensor is arranged on the outer surface of main body, and is mutually permanently connected with main body; The number of light sensor is more than one.

Described body interior is provided with the LCDs circuit, and the LCDs circuit is electrically connected with display unit and single chip circuit; This display unit is a LCDs, and LCDs is arranged at the front of main body.

The utlity model has the characteristics of simple and reasonable, environmental protection and energy saving, easy and simple to handle and long service life; It is by setting up light sensor induced environment light luminance light and shade, and luminance signal is fed back to single-chip microcomputer handle, automatically regulate the light and shade brightness of the LCDs that is arranged on the liquid heater outer surface, realize that daytime or ambient light are strong, brightness of display screen increases, evening or ambient light are dark, and brightness of display screen weakens.Can avoid can't see when daytime, light was strong displaying contents and evening ambient light secretly see the problem that the display part is too dazzling, hinder eyes.

Description of drawings

Fig. 1 is an embodiment perspective view of the present utility model.

Fig. 2 is the workflow frame diagram of Fig. 1.

Among the figure: 1 is light sensor, and 2 is main body, and 3 is LCDs.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described.

Referring to Fig. 1-Fig. 2, this liquid heater comprises main body 2 and display unit, and display unit is a LCDs 3, and LCDs 3 is arranged at the front of main body 2.Main body 2 inside are provided with the LCDs circuit, and the LCDs circuit is electrically connected with LCDs 3.Also be provided with photosensitive-member on the main body 2, to regulate the brightness of display unit.

Photosensitive-member comprises light sensor 1, and the position of main body 2 inner corresponding light sensors 1 is provided with single chip circuit, and the luminance signal input circuit of this light sensor 1 is electrically connected with single chip circuit.Light sensor 1 is arranged on the outer surface of main body 2, and is mutually permanently connected with main body 2.Light sensor 1 is electrically connected with single chip circuit, LCDs circuit and LCDs 3 respectively, and the number of light sensor 1 is one.

Operation principle of the present utility model is: by light sensor 1 induced environment light luminance light and shade, the luminance signal input circuit feeds back to single-chip microcomputer with luminance signal and handles, automatically regulate the light and shade brightness of the LCDs 3 that is arranged on main body 2 outer surfaces, realize that daytime or ambient light are strong, brightness of display screen increases, evening or ambient light are dark, and brightness of display screen weakens.Can avoid can't see when daytime, light was strong displaying contents and evening ambient light secretly see the problem that the display part is too dazzling, hinder eyes, very the consumer that considers of science neither is subjected to the strong influence of external environment light when making electrical appliance, and don't can be subjected to from the brightness of display screen of electrical equipment own in the dazzling injury to the people of night time operation.
