Abstract
The utility model discloses a colour displayer of an electric refrigerator, which is composed of a computer controller, a temperature measurement circuit and a colour display screen. The computer controller and the colour display screen are installed on an upper door of the electric refrigerator, or a top cover of the electric refrigerator, or the handle of the electric refrigerator, or between the upper door and a lower door. The colour display screen adopts a light-emitting diode as a display element. The utility model has simple structure and direct display. The utility model brings decorative beauty to the appearance mould of a traditional electric refrigerator and adds a new serial product on the family of the electric refrigerator.
Description
The utility model relates to kind of the colour display device that can simulate the household electrical appliance dynamic behavior.Be specially adapted to the demonstration of refrigerator dynamic behavior.
Refrigerator is one of the most frequently used household electrical appliance of Modern Family, and the operating temperature of refrigerator then is the topmost parameter of reaction refrigerator duty.Yet present widely used refrigerator generally all is not provided with the display unit that can directly react its dynamic behavior except that being provided with the temperature control equipment outside casing in its casing.Like this, not only can not make the user understand the dynamic behavior of refrigerator intuitively, and bring inconvenience for the setting and the operation of its temperature, that is: if will carry out different temperature settings, then must open refrigerator doors earlier, just can carry out the setting and the operation of temperature then.
In view of the above problems, the purpose of this utility model provides a kind of simple in structure, good reliability, and can react the colour display device of refrigerator dynamic behavior very intuitively.
The technical solution of the utility model is achieved like this:
The utility model includes computer controller, temperature measurement circuit and colorful display screen three parts, computer controller and colorful display screen are arranged to the doorstep or on the top cover of refrigerator, also can be arranged at refrigerator handle or the crosspiece between the upper and lower door of refrigerator on.Computer controller adopts commercially available 80 series monolithics.Colorful display screen adopts the LED light emitting diode as its display element.
Through not only simple in structure, the intuitive display of the utility model after the above-mentioned design, but also bring a kind of decorative beauty for the appearance and modeling of refrigerator, and increased new series of products for refrigerator family.
Embodiment of the present utility model is as shown in drawings:
Fig. 1, Fig. 2 are structural representations of the present utility model
Fig. 3 is a circuit diagram of the present utility model
Below in conjunction with the embodiment that provides in the accompanying drawing, concrete structure of the present utility model is elaborated:
The refrigerator colour display device includes computer controller, temperature measurement circuit and colorful display screen three parts.Computer controller 2 and colorful display screen 4 are arranged to the doorstep on 1 or on the crosspiece of the upper and lower door of the handle of top cover or refrigerator or refrigerator of refrigerator.Computer controller 2 adopts commercially available 80 series monolithics.On computer controller 2, be provided with operating key 3 and cover plate 5.Colorful display screen 4 adopts the LED light emitting diode as its display element, and it is by K switch 1, K2, K3, and triode T1-T8 and the four groups of luminous utmost point two pipes of LED are formed.The base stage of triode T1-T8 is connected with the PB mouth of single-chip microcomputer IC, and four groups of LED light emitting diodes are connected with the PA mouth of single-chip microcomputer by resistance.Temperature measurement circuit is arranged in the refrigerator.On temperature measurement circuit, be provided with sensing element B, C and resistance R 1, R2.
Working method of the present utility model is achieved like this:
The control circuit input voltage is 220V, after the DB-5 transformation, after the rectification circuit rectification via the D1-D4 formation, a stable operating voltage VDD is provided for single-chip microcomputer IC through mu balanced circuit A again.
A/D1 and A/D2 that the collected signal of sensing element BC in the temperature measurement circuit inputs to single-chip microcomputer connect, and are converted to temperature data by single-chip microcomputer.Output circuit drives relay J work by the delivery outlet PA7 of single-chip microcomputer through triode T0.
During use, the operator can carry out the setting of refrigerator work temperature by the button 3 (being K1, K2, K3) that is arranged on the outer computer controller of electric refrigerator housing body, and checks its duty curve.The colorful display screen of being made up of four groups of LED light emitting diodes then can reflect the dynamic duty situation of refrigerator very intuitively.
