Furthermore, 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 water sprinkler body 4 via a circulation pump 9, The ice-making water in the 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, ice 10 is formed on the ice-making plate 1.

However, in the conventional configuration as described above, since the injection holes 4a of the water sprinkler body 4 and the ice-making plate 1 are too far apart, the injection direction of the ice-making water to the ice-making plate 1 and the discharge of the ice-making water circulation pump 9 are limited. The degree of scattering of the ice-making water changes greatly due to the pressure, and furthermore, turbulence occurs in the ice-making water flowing down the ice-making plate 1, which prevents the growth of an even ice-making layer, making it difficult to make stable ice. The installation 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 devices.

Furthermore, in the conventional configuration, since the plate 5 is positioned on the holding portion 3 of the ice-making plate 1 using only the screws 6, it is impossible to obtain a highly accurate mounting position. Ta. 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 a highly effective means for quickly eliminating the various drawbacks described above. a water sprinkler body, a water spray guide plate provided on the outer side of the water sprinkler body, a holding protrusion formed to hang down from the bottom plate of the water sprinkler body, and a pair of water sprinkler guide plates provided at both ends of the water sprinkler body. The ice-making plate is characterized by a configuration in which the ice-making plate is sandwiched between the rising portion and the holding protrusion, thereby accurately determining the connection position between the water sprinkler body and the ice-making plate. It is.

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 the same parts as in 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 large number of injection holes 4a are provided in the holding part 3 formed at the upper end of the ice making plate 1.
A water sprinkler body 4 is mounted, which is provided with water sprinkler bodies 4 at regular intervals in the longitudinal direction. A holding plate 4b having an 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 this holding plate 4b in a manner to be described later. It is being

As shown in FIG. 2, the water sprinkling guide plate 4c is detachable at 3 so as to correspond to each of the plurality of injection holes 4a formed in the water sprinkler body 4 provided at the upper end of the elongated ice-making plate 1. is positioned.

Furthermore, the water sprinkling guide plate 4c is constructed as shown in the perspective views shown in FIGS.
The main body part 4e of c is formed with a chevron-shaped protrusion 4f extending from its end edge so as to have a substantially triangular pyramid shape as a whole, and
The base of the triangular pyramid is formed so that it does not come into contact with rising portions 41 and 4j, which will be described later. Watering guide plate 4c
A pair of rising portions 41, 4 are provided at both ends of the main body portion 4e.
j is provided in a substantially vertical direction, and each rising portion 41, 4
The cutout portion 4k formed at j is provided corresponding to the corner portion of the water sprinkler body 4. Therefore, the retaining plate 4 of the sprinkler body 4
By fitting the top of each sprinkler guide plate 4c (on the opposite side of the chevron-shaped protrusion 4f) between the corner portion and the corner portion as shown in FIG. It can be detachably attached to. Furthermore, as shown in FIGS. 6 and 7, the tip of the chevron-shaped protrusion 4f has a chamfered portion 41 on its back side (that is, the surface through which ice-making water does not flow). The structure is such that ice-making water falling on the surface of the chevron-shaped protrusion 4f does not go around to the back side. Further, the bottom plate 4w of the sprinkler body 4 is provided with a holding protrusion 4x that is formed to hang down in a substantially vertical direction and has elasticity, and fixes the sprinkler body 4c at a predetermined position on the ice-making plate 1. As shown in the enlarged diagram in FIG.
The ice-making plate 1 is fixed by being joined to each side 1a of the ice-making plate 1.

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, when operating the water sprinkler for an ice making machine according to the present invention, first, the freezing evaporator 2 of the ice making plate 1 is cooled by the refrigerant sent by the compressor (not shown). Then, 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 ice is dispersed to the left and right by the chevron-shaped projections 4f, flows down uniformly without being particularly concentrated in the center, and is guided onto the ice-making surface 1a. In the embodiments detailed above, the case where the ice-making layer is grown only on one side of the ice-making plate has been described, but as shown in FIGS. 9 to 11, ice-making water is grown on both sides of the ice-making plate 1. Exactly the same effect can be achieved with a configuration in which the above is supplied.

That is, in FIGS. 9 to 11, a pair of L-shaped holding plates 4b, 4b are integrally formed on both outer sides of the sprinkler body 4, and each holding plate 4b, 4b has a respective watering guide. Board 4

It is arranged so as to correspond to the hole 4a and to be located between each guide rib 1b.

Since the water sprinkler for an ice maker according to the present invention has the above-described configuration and function, various experiments were repeated to attach the sprinkler body to the ice making plate, and the installation was performed so that the flow of ice making water was at an optimal level. After setting the angle of the holding protrusion of the sprinkler body and the joint of the sprinkler guide plate so as to match the position, each part can be manufactured and installed, and any person can easily install it without any adjustments. The water sprinkler body can be attached to the ice-making plate with a single touch, and the optimal ice-making water flow can always be obtained.

Therefore, the water guide plate makes it possible to obtain a uniform flow without phenomena such as turbulence, concentrated falling, or turning around to the back side, and it is possible to stably grow ice with a uniform thickness. .
