Problems solved by technology

And once you press it once more, you have to go through a cycle again, which greatly reduces the convenience for users
[0011] In order to solve the above problems, the figure 1 The operation key 41 or operation key 43 described in is modified as figure 2 The temperature increase operation key 45b or the temperature decrease operation key 45a shown in , changes the one-way adjustment into a two-way adjustment. Even so, the user still needs to use fingers to repeatedly press the operation, which is still not very convenient for the user, and because With repeated pressing, the keys are more prone to wear and tear, resulting in a reduction in their lifespan

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] From image 3 We can see in the figure that the control device of the present invention includes a panel on which a display unit and operation keys are arranged. The display unit uses LEDs to display the working status of the refrigerator, and the operation keys are used to input various instructions for operating the refrigerator, such as quick freezing, child lock, etc. On the rear side of the panel, a single-chip microcomputer is arranged. The single-chip microcomputer is connected with the display part and the operation keys through wires, and the single-chip microcomputer is used to control the work of the refrigerator, and the operation keys are touch-type or button-type operation keys.

[0025] The set temperature of refrigerator is regulated by sliding thermostat 46, from image 3 As we can see in the figure, the sliding temperature adjustme...

Abstract

The invention provides a refrigerator operating device. The input operation of temperature increment and reduction of corresponding storage chambers of a refrigerator is realized by left and right slide of a finger of a user, and meanwhile, a euphotic passage is formed in an operating key to indicate a light source for irradiation so as to clearly display the position of the operating key on a panel. Compared with the prior art, the refrigerator operating device has the advantages that time and labor are saved in operation and the convenience for the use of the user is greatly improved.

Description

technical field [0001] The present invention relates to a refrigerator control device, more specifically to a control device for user operation to increase or decrease the temperature of a storage room corresponding to the refrigerator. Background technique [0002] In the prior art, in order to control components such as the refrigerant circulation device of the refrigerator, the lighting device of the storage room, and the temperature sensor, a control unit is provided in the refrigerator, such as figure 1 As shown, the control unit 4 includes: 1) a circuit (not shown in the figure), which is electrically connected to the above-mentioned devices; 2) a display unit 5, which is used to display the temperature inside the refrigerator and the operation content of the above-mentioned user, etc. Information; 3) Operation key 4a, which can transmit a signal to each circuit of the control unit 4 when the user operates the key. [0003] The display unit 5 is generally composed of ...
