Ice making module of vertical auger type ice maker

The present invention relates to an ice module of a vertical auger type ice maker (Icing module, an auger type ice maker assembly unit in which an ice maker, an ice maker and a bearing unit are integrated, hereinafter referred to as an ice maker), and in particular, It is limited to two, and the number of bearings (bearing, bearing, hereinafter referred to as the number of rotation shafts) supporting the upper rotation shaft of the auger (integrated with the rotation shaft and spiral blade, hereinafter referred to as auger) of the vertically installed ice maker is deleted. ) relates to an ice-making module of a compact vertical auger type ice maker with improved hygiene and removal of wear and foreign substances caused by contact of rotating shafts with ice.

Auger-type ice maker is an auger (a rotating shaft and a spiral blade integrated together, hereinafter referred to as auger) consisting of an auger (screw shape, hereinafter referred to as a spiral blade) coupled to a circular shaft member (Auger shaft, hereinafter, referred to as a rotating shaft) of the ice maker. ), a cylindrical ice-making cylinder surrounding the auger (an outer cylinder member through which ice-making water can circulate, and an auger is installed inside, hereinafter referred to as the inner cylinder member), and one or more spirals positioned between the inner wall of the inner cylinder member and the auger A guide rib (hereinafter referred to as a guide rib) formed in the compressed section of auger shaft (located on the upper part of the inner cylinder member, hereinafter referred to as the compression unit) and a guide rib for ice growing by cooling the coolant flowing through the blade It guides the growing ice between them to a passage (hereinafter referred to as a compression passage) that rises by the auger rotational force, and at the same time dehydrates in this compression passage, removes moisture, pushes it up to a hard ice column, and at the same time pushes it up to the upper pressure head (inner cylinder member upper part) It has a structure in which the ice on the column is cut into chips by contacting the lower inclined surface of the finishing member separately configured in the , hereinafter referred to as the pressure head) and discharged to the storage.

The cooling principle of this auger type ice maker is a refrigeration cycle, 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 a heating medium called refrigerant. In the following, the ice making water in contact with the refrigerant passage through which the refrigerant circulated to the four elements constituting the This is called a cooling cycle (A).

The cooling structure using such a cooling cycle (A) is provided with an outer cylinder 131 having a refrigerant inlet and outlet, and an inner cylinder 130 spaced apart from the outer cylinder 131 at a predetermined interval, and the shorter length of the inner cylinder 130 and the outer cylinder 131 . It has a vertical double cylinder structure in which both ends are sealed as a standard, and when ice making water freezes on the inner wall surface of the vertical double cylinder inner cylinder 130 by the cold air circulating in the spaced apart space of the vertical double cylinder, the inner side of the inner cylinder 130 In order to continuously scrape the ice frozen on the wall and compress it in the longitudinal direction of the vertical double cylinder, it has an outer diameter that can form a certain gap with the inner side of the inner cylinder 130 and the inner side of the inner cylinder 130, and has a spiral blade of 1 pitch or more on the outer periphery. A rotating auger 10 formed with 102 is installed to circulate refrigerant in the outer cylinder member formed on the outer periphery of the inner cylinder member to cool the inner cylinder member to below the freezing point to freeze the ice-making water flowing into the inner cylinder member, and by this freezing The growing ice layer is scraped upward by an auger and introduced into the compression passage of the pressure head while being transported, and compressed (dehydrated) in the compression passage to be compressed into a hard ice column from which moisture has been removed, and the ice column is transferred to the compression passage It comes into contact with the inclined surface of the upper pressing head with a pressing force, is cut into chips of an appropriate size, and is stored as a standardized ice mass (hereinafter referred to as chipped ice), and the chipped ice is stored in the storage chamber.

The chipped ice stored in the storage chamber must be maintained in the form of chips for the quality of the ice until it is discharged for drinking.

However, in conventionally known storage chambers, there is a problem in that some of the stored ice is essentially melted due to inaccurate cooling management, and the ice on the chip that has just been stored and the ice in a state in which each side of the ice has a longer storage time is discharged first or together.

Moreover, a stirring blade is installed on the bottom side of the storage chamber to prevent the sticking of ice cubes and to discharge them smoothly to the ice exit. Although the ice rotates in the rotational direction of the stirring blade, there is a problem in that some melted ice rises and exits in the gap between the end of the stirring blade and the inner wall of the storage chamber.

For example, the force (F, kg) applied in the lateral direction of the auger can be known from the output (P, watt) of the motor, the radius (R, cm) and the number of revolutions (N, rpm) of the auger. When P = 15 (watt), auger radius R = 1.5 cm, and auger rotation number N = 10 rpm, the lateral force (F) applied to the auger on the ice exit side that takes the most force is,

F = (P x 10.2)÷(2 x 3.14 x N÷60)÷R

(L ₀ =L ₁ +L ₂ , where L ₁ is When the one smaller than L ₂ will calculate tentatively)

<Table 1>

* F2 & F3

F1 x 10 = F2 x 4, F2 = F1(97.5kg) x 10 ÷ 4 = 243.75kg

F2 = F1 + F3, F3 = F2 - F1 = 243.75- 975 = 146.25 kg

1) Deformation σ= F1 x 6 ³ ÷(3 x E x(3.14 xd ⁴ /64))

= 97.5 x 6 ³ ÷(3 x 2100000 x(3.14 x 1.7 ⁴ /64)) = 0.008 cm = 0.08 mm

2) Bending moment M = F1 x 6 = 97.5 x 6 = 585kgcm = ð x Z (section modulus of the axis where the force is applied)

3) Bending stress ð = M÷Z, Z=3.14 x 1.7 ³ /32=0.482 = 585÷0.482= 1213kg/cm2 (It is safe because it is less than 1/4 of the material stress, which is the standard for general engineering safety judgment)
