Control method for making rice in refrigerator

Abstract

The invention discloses a control method for making ice in a refrigerator. The specific method is characterized in that the temperature in an ice making box is detected by adopting an infrared temperature sensor; and the ice making process in the ice making box is controlled by the detected temperature signal. Due to high response speed of the infrared temperature sensor, current actual temperature in the ice making box in the ice making process can be detected in time; the ice making process of the ice making box is controlled by adopting the current actual temperature in the ice making box;and the control method has higher reliability, and further the ice making efficiency can be effectively improved, and the ice making effect is ensured.

Description

technical field [0001] The invention relates to the application field of household appliances, in particular to a method for controlling ice production of a refrigerator. Background technique [0002] A refrigerator is a household appliance that refrigerates and / or freezes food through a refrigeration cycle. With the increasing diversification needs of users, quickly making ice cubes has become an important function of the refrigerator in addition to food preservation. [0003] The ice-making room used to make ice cubes is generally located at the storage room or the door of the refrigerator. The ice-making room has an ice-making box and a temperature sensor for measuring the temperature inside the ice-making box. in the control signal. The ice-making process is: the water supply system of the refrigerator supplies water to the ice-making chamber. After the water is supplied to the ice-making box, the cold air is introduced into the ice-making chamber through a fan or a fix...

Problems solved by technology

[0004] However, the temperature sensor generally used in the current industry is an NTC resistance temperature sensor. This temperature sensor is installed at the bottom of the ice box, and its response time is slow (often more than half a minute), that is, it cannot sense the actual temperature in the ice box in real time. , the sensed temperature signal often has a large hysteresis

In this way, the existing design cannot achieve precise control during the ice-making process of the ice-making box, resulting in problems such as low ice-making efficiency and high energy consumption.
