The ice maker includes a ice maker frame 1, a ice-making drum 10, an ice-making water tank 20, a cooling unit 30, a blade unit 40, a water storage tank 50, And a pumping unit 100.

The ice making machine frame body 1 has a bottom portion 13 which is a dropping position after leaving the ice making compartment at the bottom of the front face, 13 except for the outlet portion 11, the bottom portion 13 and the opening portion 14 are formed of a casing having a predetermined shape for covering the inside thereof. Similar to the shape of a known small water purifier or domestic water purifier, the remainder except the front is made up of a casing of a cube. In particular, the viewing window 12 is formed on the front surface of the exit portion 11, and the direct downward air space in which the snowboard falls down forms the opening portion 14. A cup (hereinafter referred to as a container) And the inside of the bottom portion 13 is also covered to protect the driving motor 62 and the like described later.

The ice-making drum 10 is rotated and driven by known driving means. The ice making drum 10 may be provided with a coolant spray nozzle for cooling the outer circumferential surface so that ice (I) is formed on the outer circumferential surface. The cooling structure of the ice-making drum 10 is generally known, and therefore, it will be schematically described.

The cooling of the ice-making drum 10 can be installed in the horizontal center portion of the ice-making drum 10 so that the refrigerant expanded through the cooling unit 30 is injected as an atomizing nozzle through the evaporator in the center direction. In the ice making drum 10, the evaporator extends on the central axis in the cylindrical drum and sprays from the inside of the drum through the spray nozzle or the like to freeze the deicing water contacting the outer circumferential surface.

The configuration of the evaporation of the refrigerant disposed inside the ice-making drum 10 is already known in various ways, so a detailed description thereof will be omitted. As a technology of the coolant injection inside the ice-making drum, any one of well-known methods is selected as the prior art.

The ice-making water tank 20 contains de-iced water W through a water supply line of a separate water storage tank 50. The ice-making water (W) of the ice-making bath (20) is kept immersed so that the outer peripheral surface of the ice-making drum (10) is contacted with a predetermined depth. The ice-making tub 20 is positioned directly below the ice-making drum 10 so that the outer peripheral surface of the ice-making drum 10 contacts with the rotation.

The cooling unit (30) supplies the inside of the ice making drum (10) with coolant to cool the outer peripheral surface of the ice making drum (10).

In the drum type ice-making machine having such a structure, the ice-making drum 10 rotates as soon as the container is placed on the turntable 60, and at the same time, the ice-making drum 10 rotates for a predetermined time after the ice- 20 and the evaporated refrigerant applied to the inside of the ice making drum 10 freezes the outer circumferential surface of the ice making drum 10 so that a predetermined amount of snow falls by the blade 40 on one side of the ice making drum 10, The ice-making is performed until a certain amount of snowboard is filled in the container on the ice tray 60. At this time, the rotation of the turntable (60) in the bottom part (13) is carried out so that the snowing is uniformly accumulated in the vessel. The ice-making drum 10 is automatically stopped when the ice-making process is completed.

In addition to the operation of putting these snowboards in the container, the present invention should drive the ice drum again in order to put the snowboard in the container after a short or long wait. At this time, the inventive ice-making machine can lower the height of the ice-making bath 20 or reverse the ice-making water to the water storage tank 50 during the waiting time. So that even when the cooling unit 30 of the ice-making drum 10 is in operation, the ice-making drum 10 is prevented from freezing on the outer circumferential surface thereof, and the ice-making drum 10 is constantly cooled and discharged with good quality.

The formation of such ice lumps is caused by the fact that the ice making drum 10 is immersed in the ice making water tank 20, and various methods for preventing this are possible.

[ The link member 74 is rotatably connected to the first connection link 74a and one side of the ice-making water tank 20 so that the second link link 74b is rotatably connected to the other link link 74a. And the other side of the second connection link 74b is connected to the drive shaft 73. [

The guide portion 80 is formed with a guide protrusion 21 on the other side of the ice-making water tank 20. The guide protrusion 21 is provided at a predetermined distance from the guide slot 80 of the sliding bar 82 81 and engaged with the first and second connection paths 74a, 74b of the drive shaft 73 and the link member 74 when the rotational force is applied to the range determined by the step drive of the drive motor 71 Thereby lowering the ice-making water tank 20 a predetermined distance from its original position. Reference numeral 83 denotes a sliding groove.

The link member 74 may be a link means or the like which is appropriately eccentric to a distance at which the water level in the ice making drum 10 is lowered to a position where the water level of the ice making drum 10 is not in contact with the ice making drum 10. [

The installation structure of the low-bingo 90 is composed of a casing of a cuboid without the openings 14 of the above-described embodiment, and has a construction of a predictable ice maker. Since such an ice-maker has an ice-making structure for drawing the ice bank accumulated in the internal low ice bank 90, the low ice bank such as this ice bank is generally used in a low bingo provided in an ice maker such as the known Japanese Patent No. 10-1384482 and 10-1474544 . The description of the concrete construction and operation is merely the same as that of the first embodiment described above with respect to the low-bingo 90, and a detailed description thereof will be omitted.
