Description

Ice making apparatus using rotation cutting blade {Ice making apparatus using rotational cutter}

The present invention relates to an ice making apparatus, and more particularly, to an ice making apparatus capable of cutting ice formed in a tube shape by a refrigerant into a predetermined size.

In general, an ice maker stores water in various ice trays having a plate, a tube, a cell, or a block to form water or the ambient temperature below the freezing temperature. It is a device to freeze the water stored in the ice making container.

It is largely divided into a method of producing ice by storing an ice maker in the same place as a freezer and a method of producing ice by applying the ice maker itself to an evaporator structure of a freezing cycle.

The method of producing ice by applying the ice making container itself to the evaporator structure of the refrigerating cycle is a compressor for compressing the refrigerant into a gas of high temperature and high pressure, and the temperature and pressure to promote the evaporation of the condensed refrigerant. In a general refrigeration cycle consisting of an expansion valve for descending and an evaporator for absorbing external heat to evaporate the refrigerant, the evaporation structure of the refrigerant is combined with the ice making vessel to reduce the temperature due to the evaporation of the refrigerant. To freeze the water.

As described above, the most widely applied form of the conventional ice making apparatus using the refrigerating cycle is as shown in FIG. 1. 1 is a side cross-sectional view showing a conventional tubular ice maker.

A plurality of ice making tubes 12 are installed in a cylindrical body, and a case 10 in which a coolant flow space is formed by upper and lower partitions 10a and 10b and the ice making tube 12, and the case ( 10 is provided with a distributor 11a at the top of the distribution tank 11 for supplying water into each ice-making tube 12, and is installed in the lower portion of the case 10 to each ice-making tube 12 It is composed of a discharge tank 14 for discharging the ice falling from the).

In addition, the discharge tank 14, the cutting member 17 for cutting the ice dropped from the ice making tube 12, and the ice cut to a predetermined size by the cutting member 17 of the discharge tank 14 An ice outlet 14a for discharging to the outside and a storage tank 15 for separating and storing water falling from the ice making tube 12 from the ice by the screen plate 16 are provided, and the cutting member 17 is provided. Is installed to be rotatably supported by the lower rotary shaft (17a) and the storage tank 15 is made of a configuration connected to the distribution tank 11 by a return pipe 19 having a circulation pump (18).

The conventional ice making device 1 is configured to introduce a refrigerant through a compressor, a condenser, and an expansion valve (not shown) into the refrigerant flow space 13 through a refrigerant inlet pipe 13a installed under the case 10. At the same time, water flows down from each of the distribution tanks 11 through the respective ice making tubes 12 so that ice gradually builds up from the inner surface of the ice making tube 12, and the refrigerant used in the ice making is Re-flowing into the compressor through the refrigerant discharge pipe (13b) installed on the upper side to continuously perform the ice-making operation by the refrigerant, the water not frozen in the ice-making tube 12 is stored through the screen plate (16) 15 is supplied to the distribution tank 11 through the circulation pump 18 and the return pipe 19.

When a continuous ice-making operation is performed and ice of a certain thickness is frozen inside the ice-making tube 12, some of the hot gas, which is sent from the compressor of the refrigerating cycle, to the condenser, is transferred through the refrigerant discharge pipe 13b. The ice flows into the refrigerant flow space 13 to de-ice the ice from each ice-making tube 12, and the ice-freed ice falls to the discharge tank 14 by its own weight and rotates at the same time as the cutting member 17. After cutting to a certain size by the centrifugal force is discharged to the outside through the ice discharge port (14a), after such a defrosting operation is completed, the refrigeration cycle is normally operated to perform the ice making operation again.

However, in the case of the conventional ice making apparatus, the cutting member has a problem that the cut surface of the ice is irregular because the cutting member is a structure that cuts strongly by cutting the ice.
