Device with ice crusher and refrigerator

Abstract

The invention relates to a device with an ice crusher and a refrigerator, aiming at ensuring the ice-crushing ability and realizing the purposes of saving energy and enhancing reliability in the device with the ice crusher. The device with the ice crusher is provided with: an ice crusher which positively rotates a rotating blade and clamps ice with a fixed blade for crushing, a driving device fordriving the rotating blade, a control device for controlling the driving device and a detection unit for detecting the constraint status of the driving device, wherein, the control device is controlled as below: in case of detecting the constraint status of the driving device by the detection unit, the rotating blade is caused to implement positive rotation subsequent to reversed rotation and thetransition from the reversed rotation to the positive rotation is repeatedly controlled, and in case of the repeating times exceeding the prescribed times, the driving device stops operating.

Description

technical field [0001] The present invention relates to a device and a refrigerator provided with an ice crusher, and is particularly suitable for a freezer-refrigerator in which an ice crusher is arranged in a freezing chamber. Background technique [0002] Conventional devices equipped with ice crushers include a type in which ice cubes are crushed between a rotating blade rotated by a drive device such as a motor and a fixed blade fixed to the ice crusher housing. In this type of device equipped with an ice crusher, the driving device may be in a restrained state because the ice cubes are not broken all at once, or the ice cubes are piled up between the rotating blade and the fixed blade. [0003] Then, the ice crusher described in Unexamined-Japanese-Patent No. 5-180548 (patent document 1) was researched. Patent Document 1 discloses that an ice crusher for making ice flakes by rotating the rotary blades to crush ice thrown into the hopper is equipped with a motor that r...

Problems solved by technology

[0005] However, in the ice crusher of Patent Document 1, the driving device is stopped when the ice cannot be crushed by one forward rotation of the rotary cutter, so the ice crushing ability is low.

[0006] On the other hand, in the ice crusher of Patent Document 2, when ice enters in an uncrushable state or an uncrushable foreign object enters, the reverse rotation and forward rotation of the movable teeth are continuously repeated, thereby Causes a waste of energy and a decrease in the reliability of the movable part

[0007] Moreover, with regard to Patent Documents 1 and 2, when a foreign object of the same size as an ice cube enters and the ice cannot be crushed, the user must put his hand into the ice crusher to take out the foreign object, and there is a problem that it costs money to restore the ice crusher. a matter of time
