Description

Improved compressing structure of auger type ice maker

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auger ice machine. In particular, the ice conveyed by an auger disposed coaxially in an ice making cylinder is compressed at a low speed to form a hard ice column from which water is removed, An auger ice maker having an improved compression structure that separates and assembles an auger shaft outer-surface structure into a pressurized head and a cylindrical body.

Generally known auger ice maker cools ice making cylinders below freezing point by circulating pressure-reducing refrigerant in a spirally fixed evaporation tube which is in close contact with the outer circumference of the ice making cylinder. And a refrigerant circulation system connected to the refrigerant valve by a refrigerant pipe, hereinafter referred to as a cooling cycle, A) freezes ice-making water flowing into the ice-making cylinder, and lifts and transports the ice layer growing by the auger upwards by the auger. By introducing into the compression passage of the pressure head and compressing (dehydrating) in the compression passage, it is compressed and grows into the hard ice column M from which most of the water is removed, and this ice column M is pushed out of the compression passage. By contacting the upper ice cutting section (pressing head), the ice is cut into chips of moderate size by adding force to the outside direction. It is known that it becomes a lump (henceforth chip-shaped ice), and this chip-shaped ice is made to be stored in a storage part.

The pressurizing head for forming the compression passage of such an auger ice maker is radially radial from the outer periphery of the body part which consists of a bearing which rotatably supports the upper end side of an auger, for example in Unexamined-Japanese-Patent No. 8-189736. A plurality of compression ribs protruding and extending in the axial direction are provided in a cylindrical axial direction on the outer periphery of the auger shaft, and a compression passage having a cross section concave outwardly is formed between the respective compression ribs, and is perpendicular to the upper portion of the compression passage. To form a head portion to be connected is formed with an ice cutting unit having an inclined portion.

The auger ice maker provided with such a pressurizing head is an auger ice maker consisting of an ice maker cylinder, an auger and a refrigerant pipe, and has an inclination angle of 35 to 45 inclined angles of the outwardly inclined ice cut section provided on the upper side of the compression passage of the pressurizing head. It has also been proposed that the diameter should be set to, and the diameter of the upper head of the pressurizing head having the cut portion should be set to 27 to 37 mm.

Thus, the pressure head forming the ice pillar (M) forms a compression passage to form a bearing (bush) coupling structure between the upper auger shaft, but gradually grows due to freezing between the auger's spiral blade and the ice making cylinder. Due to the strong pressure in the direction of the auger axis (center axis) due to the ice making pressure of the ice layer, that is, radial radial load occurs due to the difference in the pressure generated between the ice making areas between the spiral blades. Left and right flows of the shaft center are generated in which the central axis of the auger shaft is slightly separated from the upper shaft number with respect to the lower shaft number. This left and right flow eventually causes friction between the rotating shaft and the lip members (compression ribs, compression ribs) in contact with the slip shaft, which causes the inner wall of the ice making cylinder and the abrasion.

In the related art, as shown in FIG. 1 of the accompanying drawings, a bush is inserted into and installed on the upper inner circumferential surface of the pressurizing head to prevent abrasion due to contact during rotation of the auger shaft between the pressurizing head and the auger shaft. The bush is installed between the rotating shaft and the fixed shaft of low speed rotation to prevent abrasion and damage of the part contacting the rotating shaft and the fixed shaft due to the friction of the other housing during rotation. Most Auger ice makers apply the above radial load Bushes have been adopted to prevent this.

On the other hand, since the compression passage of the pressing head (including the bushing) installed in the concentric cylindrical shaft on the auger rotation shaft in the ice making cylinder should be radially formed in the pressing head body, forming the compression passage at regular intervals on the outer circumferential surface of the cylindrical metal having the central shaft hole. In order to form several compressed ribs at radial precise intervals, the precision of mold design or metal processing is required by machining them, and the problems such as processing time for processing them and excessive labor due to precise mold processing have been considerable. .

As described above, since the bush mounting structure for preventing radial load due to the axle shaft tilting on the inner circumferential surface of the conventionally known pressure head has to be implemented in the pressure head, there is a problem of a complicated structural design due to the bushing insertion. There was a problem that it is difficult to compact the size of the auger ice maker according to the mounting. In addition, there is a problem in that the corroded foreign matter, gray material is generated due to prolonged contact wear with the bush.

In addition, since the cutting head pressurizing head has a structure in which the pressing head forming several compression passages is integrally formed in a cover shape covering the upper part of the ice making cylinder, the metal processing of the compression head integral with the pressing head of the cutting portion integral with the inclination angle is performed. The difficulty of the city is very high, and the manufacturing process takes a long time, and the processing of the compression part made of such precision metal material not only increases the labor cost, but also the cost of the metal material forming the cut part is very high. It also acted as a deterrent to purchasing and dissemination.

In addition, the connection structure of the lower end of the auger shaft and the drive shaft for transmitting rotational force is coupled to the spherical shaft as a cylindrical landing cover, as well as the problem of abrasion (bush) due to the radial load, as well as unnecessary complicated connection structure for coupling the spline shaft There has been a need for improvement.
