Description

[Detailed Description of the Invention] The present invention relates to an ice-making machine that generates ice cubes using an ice-making member in a tank filled with ice-making water, and discharges and stores the ice cubes outside the tank.

BACKGROUND ART Conventionally, ice makers of this kind have been known, in order to discharge the ice blocks out of the tank, those in which the tank itself is moved, or those in which the ice blocks are discharged by a scraping device that scrapes out the ice blocks.

The present invention is an improvement on the latter type, and aims to achieve miniaturization by defining various devices for driving or sensing within a predetermined range.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is the main body of the ice maker, which is surrounded by an outer box 2, an inner box 3, and a heat insulating material 4 filled between the boxes 2 and 3.

An ice block outlet 5 is formed on the front surface of the ice maker body 1, and a heat insulating door 6 is pivotally attached to the outlet 5.

On the other hand, a water supply tank 7 for supplying ice making water is provided in the upper part of the ice making machine main body 1 and can be inserted and removed from the outlet 5, and in the lower part there is an ice making section 8 that produces and discharges ice blocks, and a water storage section 9 that stores ice blocks. are divided into sections.

Here, the configuration of the ice making section 8 will be explained.

Reference numeral 10 denotes a substantially rectangular ice-making tank that is always filled with a predetermined amount of ice-making water by a water supply tank 7, and a number of ice-making cores 12, 12 on the bottom surface of which exchange heat with the evaporation tubes 11 of the refrigeration cycle.
is made to stand out.

Further, on the left side wall 10a of the ice making tank 10, there is a water supply chamber 14 for introducing ice making water in the water supply tank 7 by operating a valve 13 provided in the water supply tank 7, and a float 15 for controlling a drop in the water level in the ice making tank 10. A control room 16 is provided which detects the temperature and stops the ice making operation.

Reference numeral 17 denotes an ice block scraping device for scraping ice blocks floating on the water surface of the ice making tank 10 into the water storage portion 9, and a pair of ice block scraping devices 17 are arranged along the front and rear side walls 10C and 10d of the tank 10 on the opening side of the ice making tank 10. The scraping fins 19, 19 are connected to a parallel connecting arm 19.
a and 19a, and the rotating shaft of the motor 18 is fixed to the center of one of the connecting arms 19a.

Further, 20 is an ice thickness detection mechanism that detects the thickness of ice blocks generated by the ice making cores 12, 12, etc., and stops the ice making operation and starts the dehydration operation, and is synchronized with the rotation of the motor 18. The detection arm 21. The detection switch 22, etc., which is electrically connected to be activated by the detection arm 21 and perform the above operation, is used.

The ice block scraping device 17 and the ice thickness detection mechanism 20 are each fixed to the opening side of the ice making tank 10.

That is, the drive motor 18 is connected to the left side wall 1 of the ice making tank 10.
It is fixed inside a cylindrical mounting board 23 that is fixed to the flange 10a' of 0a and extends inside the tank.

Furthermore, the flange 10 on the right side wall 10 b of the ice making tank 10
A mounting board 24 symmetrical to the mounting board 23 is also fixed to b', and within this mounting board 24 are a detection switch 22, a detection arm 21 . In order to swing this arm 21, a fixed rotating shaft 25 is arranged at the center of the other connecting arm 19a.

Also, the rotation locus of the sweeping fins 19, 19 is naturally similar to that of the ice making tank 1.
It is within the extension line of the front and rear side walls 10C and 10d of 0.

As described above, the ice block scraping device 17 and the ice thickness detection mechanism 20 are installed on the left and right front and rear side walls 10a of the ice making tank 10, respectively.

10 b , 10 C, and 10 d.

Therefore, the constituent spaces inside the ice making machine body 1 include the water supply tank 7, the ice making tank 10 and its extension, and the water storage section 9.
The ice making tank 10 can be provided close to the internal left and right side walls 1', and the overall size can be reduced.

As is clear from the above description, the ice making machine of the present invention includes a substantially rectangular ice making tank filled with ice making water, and an ice making core that is arranged to protrude from the bottom surface of the ice making tank and generates ice blocks. at least a pair of scraping fins arranged along the front and rear walls of the ice-making tank on the opening side of the tank and scraping ice cubes floating on the water surface out of the tank;
A pair of substantially symmetrical mounting boards fixed to the left and right side walls of the ice-making tank and protruding inside the tank, and a rotating shaft fixed to substantially the center shaft of a connecting arm fixed to one of the mounting boards and connecting the scraping fin. Since it consists of a drive motor and an ice thickness detection mechanism fixed to the other side of the mounting board and driven by the rotational movement of the connection arm to detect the ice thickness of the ice blocks generated by the ice making member, it is similar to the conventional method. The drive motor etc. do not protrude outside the tank, and the space within the main body is limited to the width and depth of the tank, making it possible to reduce the overall size.
