Problems solved by technology

[0006] The prior art with the above-mentioned structure has the following disadvantages: in the power failure compensation circuit with the memory 6, a power failure occurs during the kimchi ripening mode, and the memory 6 is in the state of storing the ripening mode
When a power failure occurs during the kimchi ripening process, it has nothing to do with the time period of the power failure. As long as the power is turned on again, it will be converted into a storage mode, so for a short-term power failure, there will be a problem that the kimchi is not cooked.

Embodiment Construction

[0015] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0016] Such as figure 2 As shown, the circuit has the following structure: the transformer 26 is connected to the power supply 24 to step down the voltage generated by the power supply 24 . Diodes D1 to D4 are connected to the transformer 26 , and the diodes D1 to D4 rectify the waveform of the alternating current passing through the transformer 26 . A capacitor C1 is connected to the diodes D1-D4. Capacitor C1 is composed of electrolytic capacitors, which eliminates the clutter in the voltage waveform and makes the voltage waveform smoother. The current smoothed by the capacitor C1 is input to the constant voltage circuit IC1. The constant voltage circuit IC1 is an element that always outputs a constant voltage regardless of the input voltage. The voltage passed through the constant voltage circuit IC1 is input to the Vdd terminal of the m...

Abstract

An "electric power lost" compensating circuit and method for the refrigerator used to prepare kimchi is disclosed. Its method includes judging if the electric power is lost by microcomputer which receives a "power lost" signal from "power lost" circuit, judging if the kimchi has done according to time when electric power is lost, outputting a signal from charge / discharge circuit to said microcomputer when the electric power is restored, and running the preparing mode for short lost of electric power or the preserving mode for long lost of electric power.

Description

technical field [0001] The invention relates to a refrigerator power failure compensation circuit and a compensation method, especially an invention on determining the refrigerator power failure compensation circuit and compensation method according to the power failure time. Background technique [0002] The kimchi refrigerator is to make the kimchi ripen by maintaining the appropriate temperature, and then store the kimchi at an appropriate temperature, so as to achieve the purpose of preserving the kimchi for a long time. After flooding the pickles, the pickles are put into the pickle refrigerator to make it through a certain period of ripening process. The above-mentioned ripening process is to provide an appropriate temperature for the soaking ripening of the pickles by the heat generated by the heater. After the kimchi is soaked and matured, the evaporator is maintained at a low temperature by means of a refrigeration cycle, and the preservation process of the kimchi i...
