Abstract

The embodiment of the invention provides an ice machine and an ice blockage detecting method and device, and relates to the field of ice-making systems. According to the ice machine and the ice blockage detecting method and device, pressure detecting values of different positions in the ice machine are acquired, then different values between the pressure detecting values and pressure preset values are calculated, and then whether the difference values meet preset conditions or not are judged, so that whether ice blockage exists in the ice machine or not is clearly and rapidly learned, and meanwhile, the position where ice blockage occurs can be accurately judged; and accordingly, the ice blockage judging and removing speeds of the ice machine are greatly increased. Therefore, the operating state of the ice machine is safer, and the service life of the ice machine is prolonged.

Description

technical field [0001] The invention relates to the field of ice-making systems, in particular to an ice machine and a method and device for detecting ice blockage. Background technique [0002] The ice machine is a kind of equipment that adopts a refrigeration system and uses water as a carrier to produce ice when it is powered on. It is a refrigeration mechanical device that generates ice after water is cooled by the refrigerant of the refrigeration system through an evaporator. [0003] The existing ice machines have the following disadvantages: firstly, it is impossible to accurately determine the position of the ice blockage, so that the problem of ice blockage cannot be solved quickly, which brings an additional burden to the ice machine; Whether there is ice blockage inside the ice machine; finally, the detection accuracy is low, and the degree of ice blockage cannot be accurately judged, so it is impossible to decide whether to run the deicing program according to th...
