Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a water tray of a so-called reverse cell type ice making machine.

[0002]

2. Description of the Related Art In this type of ice making machine, one fountain hole is conventionally arranged in the center of the opening of each ice making small chamber, and return holes are arranged close to both sides of the fountain hole. It is arranged. For this reason, the ice making water sprayed from the fountain holes collides with the ceiling of the cell and diffuses in a circular shape over the entire ceiling, and then flows down the side wall and is collected in the water tank through the return hole. Has become. Due to its structure, the ice making water sprayed from the fountain holes is less likely to diffuse to the corners of the ceiling of the cell, and the pressure of the ice making water sprayed from the fountain holes is increased by increasing the size of the circulation pump to deal with it. Alternatively, as disclosed in Japanese Patent Application Laid-Open No. 4-254175, a plurality of fountain holes are provided for each ice making chamber along an equal dividing line that divides the opening of the ice making chamber into two rectangles. ing.

[0003]

The former method not only has the problem of increasing the size of the ice-making machine when the size of the circulation pump is increased, but also increases the amount of heat generated from the drive motor of the circulation pump, thereby increasing the amount of water used for ice-making. Since the temperature of the ice making section and the atmosphere temperature of the ice making section are also raised, the growth time of the ice cubes in each ice making small chamber is lengthened and the production efficiency is lowered. In the latter method, the ice making water can be accurately jetted to the corners of the ceiling of each ice making chamber, but since there are multiple fountain holes, the ceiling of the ice making chamber directly above the fountain holes and the fountain holes in the vicinity of them. Because the fountain pressure is higher than in the corners,
It becomes an ice with a slender elliptical dent, which leads to deterioration in quality as ice cubes.

[0004]

In order to solve the above-mentioned problems, the invention according to claim 1 is such that a plurality of rectangular ice making small chambers are formed downward by a partition plate and a cooler is provided on the upper surface. An ice making chamber, having a fountain hole for supplying water for ice making provided on the diagonal line of the ice making small chamber corresponding to each of the ice making small chambers and a return hole provided in the vicinity of the fountain hole, and during the ice making operation, the ice making chamber A water tray that closes the chamber and tilts downward to open the ice making chamber during deicing operation, a water tank provided under the water tray for storing ice making water, and the ice making water in the water tank is used as the fountain There is provided a water tray of an ice making device comprising a circulation pump for circulatingly supplying each of the ice making small chambers through a hole.

According to a second aspect of the present invention, a plurality of rectangular ice making chambers having downward openings and a partition plate are formed, and an ice making chamber provided with a cooler on the upper surface, and ice making water is supplied to the ice making chamber. Therefore, a water channel extending in the longitudinal direction and having a plurality of fountain holes for supplying water for ice making corresponding to each of the ice making small chambers and a plurality of rows for each ice making small chamber, and a return hole provided at a side portion of the water passage. And a water tray that closes the ice making chamber during the ice making operation and tilts downward to open the ice making chamber during the deicing operation, and a water tank provided below the water tray for storing ice making water,
A water tray of an ice making device comprising a circulation pump for circulating the ice making water in the water tank through the fountain holes to each of the ice making small chambers.

[0006]

When the ice making water sprayed from the fountain holes provided along the diagonal line in each ice making small chamber collides with the ceiling of the ice making small chamber and diffuses, it is divided into two strips in a direction substantially orthogonal to the diagonal line. It is accurately guided to the corners of the ceiling of the small ice making room, and the ice grows from the part close to the cooling surface of each ice making small room, preventing the generation of elongated elliptical dents as much as possible and the quality as ice cubes. It can prevent the deterioration.

Further, since a plurality of rows and a plurality of fountain holes are provided in one fountain pipe in the longitudinal direction of each ice making compartment, the sprayed ice making water collides with the ceiling of the ice making compartment and diffuses. Since it is divided into two parts in the direction perpendicular to the row of holes and is accurately guided to the corners of the ceiling of the ice making chamber, the occurrence of elongated elliptical dents is prevented as much as possible and the quality of ice cubes is reduced. It can be prevented.
