Problems solved by technology

In order to ensure complete deicing, in order to ensure that the granular ice can all fall off, the existing commercial ice machines can only deicing by extending the deicing time to a sufficient fixed deicing time, resulting in low ice production and high energy consumption.

Abstract

The invention discloses a deicing method which is applied to an ice maker. The ice maker comprises an evaporation temperature sensor for detecting the temperature of an ice tray and a condensation temperature sensor for detecting the condensation temperature. The method comprises the following steps: acquiring an evaporation temperature of an ice tray working environment for a certain number of times according to a first condensation temperature after acquiring a deicing program starting signal, wherein the evaporation temperature is acquired through the evaporation temperature sensor; and outputting a deicing termination operation signal when the difference between the highest temperature and the lowest temperature in the obtained set number of evaporation temperatures is smaller than a threshold value. The deicing time node is more accurate, the ice production of the ice maker is improved, and energy is saved.

Description

Technical field: [0001] The invention relates to the technical field of deicing an ice machine, in particular to a method for deicing a granular ice machine. Background technique: [0002] Commercial ice machines generally include: compressors, defrosting valves, condensers, throttling mechanisms, ice trays, gas-liquid separators, controllers, water supply valves, water pumps, and fans. The refrigerant in the ice machine forms a circulating refrigeration circuit that liquefies and releases heat on the condenser side, evaporates and absorbs heat on the ice tray side; and the water system composed of water tanks, water pumps, water pipes, etc. introduces drinking water into the ice tray to absorb heat Cooling, so as to make ice, after the water is made into ice cubes in the ice tray, the ice cubes need to be separated from the ice tray. Inhale low-temperature and low-pressure gas and compress it to form high-temperature and high-pressure gas. After being discharged, the high-...
