Ice maker and refrigerator

Abstract

The invention provides an ice maker and a refrigerator. The ice maker comprises an ice making box, a temperature changing device and a hoisting appliance, wherein the interior of the ice making box is partitioned into at least one ice making grid to contain water for making ice blocks; the temperature changing device is positioned above the ice making box and comprises a semiconductor refrigerating plate, a first temperature changing surface, a second temperature changing surface, a first temperature changing part and a second temperature changing part, the first temperature changing surface and the second temperature changing surface are opposite to the semiconductor refrigerating plate respectively, the first temperature changing part and the second temperature changing part are in hot contact with the second temperature changing surface, and the semiconductor refrigerating plate is configured to be a refrigeration surface which enables the first temperature changing surface to be with reduced temperature in the ice making process; the hoisting appliance is connected with the temperature changing device, so that in the ice making process, the temperature changing device falls to the position at which the lower part of the first temperature changing part extends into the ice making box, and thus water from the ice making box is used for absorbing refrigerating capacity from the first temperature changing part to form ice blocks. According to the ice maker and the refrigerator, in the ice making process, the cold energy generated by the semiconductor refrigerating plate is directly introduced into water in the ice making box, so that water in the ice making box can be frozen rapidly, and further the instant freezing purpose can be achieved.

Description

technical field [0001] The invention relates to the technical field of ice making, in particular to an ice making device and a refrigerator. Background technique [0002] At present, household aluminum ice machines are generally refrigerated by a frost-free refrigeration system. Usually, the ice machine is directly installed in the freezer compartment of the refrigerator or in a closed compartment in the refrigerator room, and the cold air is blown directly to the ice box by the fan. , so that the water in the ice box freezes into ice. After the ice cubes are formed, the ice maker motor drives the ice rod or the ice making box to turn over to make the ice cubes fall off under the action of gravity. Usually, this ice-making method has low ice-making efficiency, and the water in the ice-making box generally freezes from the outside to the inside, and air bubbles are easily generated inside the ice cubes, making the ice cubes opaque. With the improvement of human living stand...

Problems solved by technology

Usually, this ice-making method has low ice-making efficiency, and the water in the ice-making box is generally frozen from the outside to the inside, and air bubbles are easily generated inside the ice cubes, making the ice cubes opaque.

With the improvement of human living standards, people's requirements for the quality of ice cubes and ice-making speed have increased, which has led to the fact that this type of ice machine cannot meet people's needs day by day.
