Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water sprinkler for an ice-making machine, and in particular, the present invention relates to a water sprinkler for an ice-making machine, and in particular, the water sprinkler body sprays ice-making water uniformly onto the ice-making plate surface.
The present invention also relates to a novel improvement for making ice that is fed without turbulence and has a uniform thickness.

This type of water sprinkler that was conventionally used is:
The configuration shown in FIG. 1 was a typical one.

That is, what is indicated by the reference numeral 1 in FIG. , an L-shaped mounting plate 5 having a sprinkler body 4 with a large number of injection holes 4a is attached with screws 6.

Further, a guide plate 7 and an ice-making water tank 8 are provided below the ice-making plate 1, and the ice-making water in the ice-making water tank 8 is sent to the sprinkler body 4 via a circulation pump 9, The ice-making water in the container body 4 is injected from the injection hole 4a onto the ice-making plate 1 and falls downward, and after a certain period of time, the ice-making water is sprayed onto the ice-making plate 1.
Ice 10 forms on the surface.

However, in the conventional configuration as described above, the injection holes 4a of the sprinkler body 4 and the surface of the ice-making plate 1 are too far apart, so that the injection direction of the ice-making water to the ice-making plate 1 and the circulation pump 9 of the ice-making water are difficult. The degree of scattering of the ice-making water changes greatly depending on the discharge pressure, and furthermore, turbulence occurs in the ice-making water flowing down the ice-making plate 1, which impedes the growth of a uniform ice-making layer, making it difficult to make stable ice. However, the position of the sprinkler body, the size of the injection hole, etc. had to be finely adjusted, making it extremely unsuitable for mass production of ice making equipment.

The purpose of the present invention is to provide extremely effective means for quickly eliminating the various drawbacks described above, and in particular, it is an object of the present invention to provide extremely effective means for quickly eliminating the various drawbacks described above. , a water sprinkler for an ice making machine having a plurality of guide ribs formed vertically on the ice making plate and provided at regular intervals in the horizontal direction, the water sprinkler being disposed at the upper end of the ice making plate; a sprinkler body, a sprinkler guide plate provided on the outer side of the sprinkler body and disposed between the adjacent guide ribs, and the guide ribs so as to fit between the adjacent guide ribs. a pair of rising portions formed substantially parallel to each other and provided at both ends of each of the sprinkler guide plates, and a plurality of injection holes arranged in the longitudinal direction of the wall plate of the sprinkler body, The ice-making water spouted from the injection hole is characterized by a configuration in which the ice-making water is uniformly flowed down on the ice-making plate via the water sprinkling guide plate, the rising portion, and the guide rib.

Hereinafter, preferred embodiments of the water sprinkler for an ice maker according to the present invention will be described in detail with reference to the drawings.

Note that parts that are the same as or correspond to those of the conventional example will be described with the same reference numerals.

What is indicated by the reference numeral 1 in FIGS. 2 to 4 is an ice-making plate that has a refrigeration system evaporator 2 and is installed vertically. A plurality of guide ribs 1b are formed in the longitudinal direction. A mounting plate 5 having a sprinkler body 4 having a large number of injection holes 4a at regular intervals in the longitudinal direction is attached to a holding part 3 formed at the upper end of the ice-making plate 1 with screws 6. .

A holding plate 4b having an approximately L-shape as a whole is integrally formed in an inclined state on the outer side of the sprinkler body 4, and a watering guide plate 4c is detachably attached to the holding plate 4b in a manner described later. installed. A gap is provided between the tip of the main body 4e of the water sprinkling guide plate 4c and the side surface 1a of the ice making plate 1 to allow ice making water to fall. It is arranged between each guide rib 1b.

As shown in FIG. 2, the water sprinkling guide plate 4c is removably positioned in correspondence with each of the plurality of injection holes 4a formed in the water sprinkler body 4 provided at the upper end of the ice making plate 1. There is. Further, the water sprinkling guide plate 4c is constructed as shown in the perspective views shown in FIGS. 5 to 7, and the main body portion 4e of the water sprinkling guide plate 4c has a substantially triangular pyramid shape as a whole from its edge. A chevron-shaped protrusion 4f extending as shown in FIG. A pair of rising portions 4i and 4j are provided in a substantially vertical direction on both sides of the main body portion 4e of the sprinkler guide plate 4c, and the notches 4k formed in each of the rising portions 4i and 4j are formed at the corners of the sprinkler body 4. The shape corresponds to the part. Therefore, by fitting the top of each sprinkler guide plate 4c (on the opposite side of the chevron-shaped protrusion 4f) between the holding plate 4b and the corner of the sprinkler body 4 as shown in FIG. Each watering guide plate 4
c can be detachably attached to the sprinkler body 4.

Furthermore, a sixth
As shown in FIG. 7 and FIG. 7, an obliquely chamfered chamfer 41 is formed on the back side (that is, the surface through which ice-making water does not flow), and a chevron-shaped protrusion 4
The structure is such that the ice-making water falling on the surface f does not go around to the back side.

Further, a guide plate 7 and an ice-making water tank 8 are provided below the ice-making plate 1, and the ice-making water in the ice-making water tank 8 is pumped to the inlet portion 4m of the sprinkler body 4 by a circulation pump 9.

In the above configuration, the case where the water sprinkler for an ice maker according to the present invention is operated is as follows.
First, when the freezing evaporator 2 of the ice-making plate 1 is cooled by a refrigerant sent by a compressor (not shown), the ice-making plate 1 is cooled to a temperature at which ice can be made. When the circulation pump 9 operates in this state, the ice-making water in the ice-making water tank 8 is supplied into the sprinkler body 4 from the inlet portion 4m of the sprinkler body 4, and the ice-making water passes through the injection hole 4a to the water sprinkler guide plate 4c. After reaching the main body portion 4e, the chevron-shaped protruding portion 4f and the rising portion 4
By providing ice-making water i and 4j, the ice-making water flows uniformly without concentrating in one place, especially in the center, and the chamfered portion 4l guides the ice-making water without going around to the back side, and the ice-making plate 1 and the water sprinkling guide Board 4
The ice falls through the gap with the tip of the ice-making plate 1 onto the side surface 1a of the ice-making plate 1 without causing turbulence, and an ice-making layer grows uniformly on the side surface 1a of the ice-making plate 1.

In the embodiments detailed above, the ice-making water is supplied to only one side of the ice-making plate in order to grow an ice-making layer on only one side of the ice-making plate. As shown in the figure, a configuration in which ice-making water is supplied to both sides of the ice-making plate 1 produces exactly the same effect.

That is, in FIGS. 8 to 10, a pair of L-shaped holding plates 4 are provided on both outer sides of the sprinkler body 4.
b, 4b are integrally formed, each holding plate 4b, 4
Each water spray guide plate 4c, 4c is removably held on b in the manner described above.

The ice-making plate 1 is held between a pair of locking protrusions 4n, 4n formed at the lower part of the water sprinkler body 4, and the tip of the water-sprinkling guide plate 4 and both sides 1a of the ice-making plate 1 are connected to each other.
