Refrigerator and control method thereof, ice making assembly of refrigerator and control methods thereof

Abstract

The invention provides an ice making assembly of a refrigerator. The ice making assembly comprises a tray, a pressure sensor, a water supplying device and an ice making assembly control module, wherein the tray comprises at least one ice groove; the pressure sensor is arranged at the bottom of the tray and is used for measuring the weight of water in the tray; the water supplying device is used for supplying the water into the ice groove of the tray; the ice making assembly control module is connected with the water supplying device and the pressure sensor respectively, and is used for controlling the opening and the closing of the water supplying device according to the water weight measured by the pressure sensor. Furthermore, the invention further provides a refrigerator containing the ice making assembly and also provides respective control methods based on the ice making assembly and the refrigerator. With the adoption of the technical scheme, the accurate ice making amount can be provided in the ice making process.

Description

technical field [0001] The invention relates to a refrigerator, in particular to an ice-making assembly of the refrigerator and a control method thereof, a refrigerator including the ice-making assembly and a control method thereof. Background technique [0002] Most of the existing refrigerators have ice making assemblies. In the ice making assembly of the prior art, the additional water tank is arranged on a predetermined side of the refrigerator, and the additional water tank is connected to the ice making tray (Ice making tray) through a pipe to supply water to the ice making tray, or the water tank is directly connected to the ice making tray through a pipe. A tap (Tap) from an external water source is connected to the ice maker tray. Both tank water supply and faucet water supply involve the control of water supply. [0003] figure 1 For existing water supply control devices. The control device adopts a mechanical control method, wherein the switch device 12 has a ...

AI Technical Summary

Problems solved by technology

[0004] However, there are some defects in the above-mentioned water supply device: 1) Since the cam 11 is driven by a motor, whether the current of the motor is stable will affect the rotation speed of the cam 11, and the speed of the rotation of the cam 11 will cause the protrusion 121 corresponding to the shape of the same notch 111 The non-contact time of the outer surface of the cam 11 is different, which leads to different lengths of water supply time, that is, the water supply volume of the tray cannot be precisely controlled; 2) If the water is supplied by a faucet, due to the different water pressures in different periods, the water supply time for the same water supply time is different. 3) During the production process of the gap 111 on each cam 11, due to different precision and size, the corresponding water supply time is different; 4) As the use time increases, the contact between the protrusion 121 and the cam 11 Poor performance, resulting in different water supply time

The above defects will lead to inaccurate ice production
