A water supply control system and control method for an automatic ice maker

Abstract

The invention relates to a water supply control system and method of an automatic ice making machine. The water supply control system comprises a water case, a water pump, a water guide mechanism, an ice making mechanism and a controller which are connected sequentially, wherein the water guide mechanism is provided with a heating device and a temperature sensor; the controller is respectively connected to the water pump, the heating device and the temperature sensor; the controller controls the operation of the ice making machine according to a temperature difference signal collected by the temperature sensor. The control method of the water supply control system is characterized in that the temperature difference signal of the water guide mechanism is collected by the temperature sensor so as to detect whether the water case is in a state of being lack of water; when the water case is in the state of being lack of water, the controller controls the ice making machine to stop operating, and can perform water adding prompt. According to the invention, the state of being lack of water for the water case is detected and controlled through collecting the temperature difference, the idle rotation of the ice making mechanism is prevented; the energy consumption is lowered effectively; the service life of the ice making machine is prolonged; water adding is prompted at the first time after water is lack; and the ice making capability of the ice making mechanism is improved.

Description

technical field

[0001] The present invention relates to the technical field of ice machines, and more particularly, to a water supply control system and control method for an automatic ice machine. Background technique

[0002] The operation of the ice machine requires water supply. In the prior art, a water box is usually installed in the water supply system of the ice machine, and a water pump is used to transport the water in the water box to the ice machine for ice making. There are roughly two types of existing ice machines that use water pumps to supply water. One type is not equipped with a water level detection and control device. It is in the state of water shortage until the human inspection is performed to add water. This method causes extra energy consumption when the ice machine is idling, and the idling of the ice machine reduces its service life. After water shortage, the inability to add water in time reduces the ice making capacity of the ice machine; The o...
