Claims

[Scope of utility model registration request]

A refrigeration refrigerant circuit is formed from a compressor, a heat exchanger that condenses the refrigerant, a pressure reducing section, a heat exchanger that evaporates the refrigerant, etc., and heats to melt frost that has adhered to the heat exchanger that evaporates the refrigerant. a timer consisting of a clock pulse counter section and a clock pulse oscillator section constituted by a binary counter; a thermostat section that detects frost formation on the heat exchanger and drives the heating means; and a defrosting section of the thermostat section. comprising a zero time reset section that resets the timer by turning on the end output and the operation switch;
1. The timer, after being reset, energizes the thermistor of the thermostat section with a predetermined count output of the clock pulse counter section and stops oscillation of the clock pulse oscillator section; A second device for regulating the defrosting time by canceling the oscillation stop of the clock pulse oscillator section using the defrosting start output signal of the thermostat section.
Defrost control device with timer operation.
