[0018] figure 1 It is a block diagram of the structure of the control circuit in the refrigerator according to the first embodiment of the present invention, figure 2 It is the basic control flowchart of the refrigerator in the first embodiment of the present invention. As shown in the figure, the refrigerator of the present invention includes a controller 10 , a door opening detection switch 20 , a temperature sensor 30 and a color-changing LED 40 .

[0019] The door-opening detection switch 20 is linked with the refrigerator door, and when the refrigerator door is opened, the door-opening detection switch 20 is turned on and sends a signal to the controller 10 . Since the door opening detection switch 20 may be a mechanical switch or an electromagnetic induction switch, its configuration is the same as that of a conventional refrigerator, and thus its detailed description will be omitted. The color of the variable color LED 40 can be controlled by the controller 40 . And...

Abstract

The invention relates to a refrigerator and a control method thereof. The refrigerator is provided with a switch, a temperature sensor, an indicator light and a controller, wherein the switch is linked with the action of a door of the refrigerator; the temperature sensor is used for detecting the actual temperature inside the refrigerator; and the controller is provided with determined temperature and controls the shining state of the indicator according to the signals coming from the switch and the temperature sensor. When the door of the refrigerator is opened and the actual temperature is higher than the determined temperature, the controller changes the shining state of the indicator light so that a user can know the change of the actual temperature inside the refrigerator and is urged to close the door of the refrigerator in time so as to achieve the aim of reducing energy consumption.

Description

technical field [0001] The invention relates to a refrigerator and a control method thereof, which can remind the user of the temperature inside the refrigerator when the user opens the door of the refrigerator, so as to urge the user to close the door of the refrigerator as soon as possible to reduce energy consumption. Background technique [0002] In conventional refrigerators, after opening the door of the refrigerator, the user does not close it for a long time, causing the temperature inside the refrigerator to rise, thus consuming more electricity for cooling again, resulting in waste of energy. Contents of the invention [0003] In order to solve the above-mentioned problems, the refrigerator of the present invention has: a switch linked with the action of the door of the refrigerator; a temperature sensor for detecting the actual temperature in the refrigerator; an indicator light; A controller for controlling the lighting state of the indicator light by signals f...
