The refrigerator also comprises a solenoid valve, a water level probe, and a controller. The solenoid valve is located at a water intake end of the water storage tank. The water level probe is located in the water storage tank, and is be used for detecting an actual water level in the water storage tank. The controller is electrically connected to the solenoid valve and the water level probe, and is used for controlling the solenoid valve to be closed when the actual water level is higher than or equal to a preset water level, and controlling the solenoid valve to be opened when the actual water level is lower than a preset water level. By means of the refrigerator, purified water can be prepared, and the amount of the prepared purified water can be automatically controlled, so that a user can take the purified water to prepare clean ice/ice water any time.

Abstract

A hot tank and a water treatment device, the hot tank comprising a tank body (1), a heat generating assembly (2) and a barrier layer (3); a top cover (4) and a bottom cover (5) are provided at two ends of the tank body (1), respectively; the heat generating assembly (2) and the barrier layer (3) are disposed within the tank body (1); the barrier layer (3) is disposed adjacent to the top cover (4) and forms a barrier cavity (6) between the top cover (4); the top cover (4) is provided thereon with an exhaust port and a water outlet pipe (42) that are in communication with the barrier cavity (6); a water outlet hole that is in communication with the barrier cavity (6) is opened on the barrier layer (3), and the water outlet hole is arranged directly opposite to a pipe opening of the water outlet pipe (42) so that a water flow that is ejected from the water outlet hole is introduced into the water outlet pipe (42). Hot water is ejected from the water outlet hole of the barrier layer (3) into the water outlet pipe (42), and the water is then directly discharged from the water outlet pipe (42). According to Bernoulli's principle, water flow within the water outlet pipe (42) has a high flow speed and low pressure intensity so as to form negative pressure, while thermally expanded water within the barrier cavity (6) is absorbed into the water outlet pipe (42) and then discharged; since the hot tank directly drives water discharge by means of water pressure, a water level difference in a water box is not required to drive water discharge, and thus a water box may be omitted, thereby reducing the volume of the whole device.
