Description

Structure that combines the ice making water tank in the cleaning unit of the drum type the ice maker}

The present invention relates to a combined structure of an ice maker and a washing unit of a modular ice maker in which an ice maker is rotatably installed in a washing unit of the drum type ice maker.

In the past, domestic patent registration No. 10-0178693 (November 24, 1998), Patent Registration No. 10-0691027 (February 27, 2007) and Patent Registration No. 10-1268911 (May 23, 2013) A drum-type ice maker has been known for producing snow ice (powdered ice) used as a material for red bean ice or ice cream at home or in stores.

Such a drum rotary ice maker includes: a cylindrical ice-making drum that rotates while supplying raw material water from a raw material water supply tank installed on the upper surface and partially submerged in an ice-making water tank in which the raw material water is temporarily stored; and the ice-making drum while supporting the ice-making drum A refrigerant pipe for injecting a refrigerant into the interior, a recovery pipe for recovering the refrigerant injected into the ice-making drum, a cutting member for cutting frozen ice on an outer circumferential surface of the ice-making drum, a driving motor for rotating and driving the ice-making drum; It consists of an outer casing that surrounds it.

The drum type ice maker is a heat pump that transfers thermal energy from a low temperature region to a high temperature region by circulation (compression → condensation (high temperature region) → expansion → evaporation (low temperature region) → compression) of the cooling medium (refrigerant). The four elements, namely, the compressor, the condenser (heat dissipation from the high temperature part), the expansion valve, and the evaporator (heat absorption from the low temperature part, the cooler), freeze (ice) the ice making water in contact with the refrigerant passage through which it passes. It is called (A).

The most difficult problem in such a drum type ice maker is washing the ice making drum and the ice making dish after ice making. Conventionally known washing structures of drum-type ice makers are known in Patent Nos. 10-2042860 (November 4, 2019), and Patent Nos. 10-2190026 (020.12.07).

In the latter case of the above guns, although the ice-making dish and the washing structure are formed as one body, it has a disadvantage that it is difficult to provide a rotational space for the entire washing machine. There was a cumbersome problem in that the ice-making dish was placed under the ice-making drum, and the ice-making dish was separated separately and then a washing unit was attached to perform washing.

The driving unit 46 of the combined structure of the ice-making plate and the washing unit of the drum-type ice maker according to this embodiment includes a third driving motor 461 and a third driving motor 461 at a predetermined position on the supporting edge 26 of the washing unit 20 as shown. , as an eccentric shaft 462 eccentrically connected to the driving motor 461, it is rotatably connected to a predetermined position on the support edge 26 of the washing unit 20 by a hinge, and the other side of the ice-making plate 30 has a fixed hinge It is installed rotatably as (34), and the support member 28 is installed to be slippery from the lower side of the ice-making plate 30. The slip member (symbol omitted) may be a ball bearing or the like.

With such a connection structure, the washing unit 20 moves forward or backward by left and right switching rotation of the third driving motor 461, and accordingly, the fixed hinge 34 of the ice-making plate 30 is It is tilted downward by the horizontal plane part 33 as an axis, and the ice-making water filled inside is emptied. After that, when the washing unit 20 is returned to its original position by driving the third driving motor 461 , the ice-making plate 30 rises to its original position, and the ice-making drum 10 is positioned on the curved portion 32 and at the same time The ice-making water is filled in the ice-making water supply and washing nozzle 70 so that the ice-making drum 10 is immersed, so that the ice-making operation can be started.

Although the embodiments of the present invention have been described with reference to the above, those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential characteristics thereof.
