Description

[Detailed Description of the Invention] Ice-making water injected from the container body is supplied uniformly to the surface of the ice-making plate without any turbulence, making it possible to produce ice of uniform thickness. This invention relates to a new improvement for easily and accurately attaching a body.

The configuration shown in FIG. 1 is typical of this type of water sprinkler that has been used in the past.

That is, what is indicated by the symbol l in FIG. An L-shaped mounting plate having a sprinkler body 14i having a large number of injection holes 4 is attached with screws 6.

Further, a guide plate and an ice-making water tank g are provided below the ice-making plate l, and the ice-making water in the ice-making water tank g is supplied by a circulation pump. The ice-making water in the water-sprinkling plate is injected from the injection hole lIa onto the surface of the ice-making plate and falls downward, and after a certain period of time, ice is poured onto the surface of the ice-making plate. lθ is formed.

However, in the conventional configuration as described above, the injection hole lIa of the water sprinkler body and the ice-making plate are too far apart, so that the injection direction of the ice-making water to the ice-making plate l and the discharge of the ice-making water circulation pump 9 are limited. The degree of scattering of ice-making water changes greatly depending on the pressure, and furthermore, turbulence occurs in the ice-making water flowing down the ice-making plate, which prevents the growth of a uniform ice-making layer. The mounting position of the ice making device, the size of the injection hole, etc. had to be adjusted in every detail, making it extremely unsuitable for mass production of ice making devices. Furthermore, in the conventional configuration, the mounting plate S having the sprinkler body II is positioned on the holding part 3 of the ice-making plate L using only screws O, so it was impossible to obtain a highly accurate mounting position. .

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 sandwiched between the rising portion 9 and the holding protrusion so that the connection position between the water sprinkler body and the ice making plate can be determined accurately. It is something that you have.

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.

The same parts as in the conventional example will be described with the same reference numerals.

What is indicated by the symbol l in Figs. A plurality of guide ribs/b are formed in the longitudinal direction. A large number of injection holes 4 (
A water sprinkler body L is mounted, which is provided with water sprinkler bodies 1 and 3 at regular intervals in the longitudinal direction.

On the outside of the water sprinkler body q, there is a retaining plate I having an L-shape as a whole.

There is a gap d between the tip of the main body part DA θ of the water sprinkling guide plate lIc and the side surface /a of the ice making plate l, which is large enough to allow ice making water to fall.
are provided, and each watering guide plate 11aVi is arranged between each guide lip /b of the ice breaking plate l.

As shown in FIG. 2, the water sprinkling guide plate ea is detachably attached to each of the plurality of injection holes 4Ia formed in the water sprinkler body provided at the upper end of the elongated ice-making plate l. Positioned. Furthermore, the watering guide plate lI
c is constructed as shown in the perspective views shown in Figs. 5 to 7, and the main body part d of the water sprinkling guide plate Qa has a chevron-shaped protrusion extending from its edge so as to form a substantially triangular pyramid shape as a whole. Part l
If is formed, rising portions ai, which will be described later,
4(j) is formed so that the base of the pentagonal pyramid does not come into contact with the base of the pentagonal pyramid.A pair of rising portions lIi, &j are provided in a substantially vertical direction on both sides of the main body portion daθ of the water sprinkling guide plate 11a. The notches lIk formed in the rising parts lIi and 41j are provided corresponding to the corners of the sprinkler body q.Therefore, each watering kite is provided between the holding plate +b of the sprinkler body t and the corner. By fitting the top of the plate Qc (the side opposite to the chevron-shaped protrusion lIf) as shown in FIG. 3, it can be detachably attached to each sprinkler guide plate PC-12.

Furthermore, as shown in FIGS. 6 and 7, the tip of the chevron-shaped protrusion 4<f has a chamfered portion q1 that is obliquely chamfered on the back side (that is, the surface through which the ice-making water does not flow).
is formed so that the ice-making water falling on the surface of the chevron-shaped protrusion 44f does not go around to the back side.

Further, the bottom plate w of the water sprinkler body q is provided with an elastic holding protrusion llx that is formed to hang down in a vertical direction, and holds the water sprinkler body C at a predetermined position on the ice-making plate l. When fixing the sprinkling guide plate Qc to the joint 4 (
y and the joint portion 11z of the holding protrusion Qx are joined to each side surface /a of the ice-making plate l to clamp and fix the ice-making plate l.

The ice-making water in the tank g is fed under pressure to the inlet portion 11m of the water sprinkler body q by a circulation bomber.

In the above configuration, when operating the water sprinkler for an ice maker according to the present invention, first, the ice maker plate/refrigeration evaporator 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 bomber operates in this state, the ice-making water in the ice-making water tank g is supplied into the sprinkler body l from the inlet lIm of the sprinkler body da, and the ice-making water passes through the injection holes 4Zai to the main body of the water sprinkler guide plate lIC. After reaching da e, it is dispersed to the left and right by the chevron-shaped protrusion '%f,
It flows down evenly without concentrating especially in the center, and the ice making surface la
You will be guided upwards.

In the embodiment 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 layers are grown on both sides of the ice-making plate l. Exactly the same effect can be achieved with a configuration in which water is supplied.

That is, in FIGS. 9 to 9, a pair of L-shaped retaining plates qb and qb are formed immediately outside the water sprinkler body.

Each water spray guide plate <<c., 4 (C) is removably attached to llb in the manner described above.

A pair of holding protrusions 11x, 4x formed on the bottom plate 4(w) of the water sprinkling guide plate 11c and a joint portion 4(y) of each rising portion lIi, 17j of the water sprinkling guide plate 11c are held in the ice making plate/. As a result, the water sprinkler body DA is fixed to the upper end of the ice making plate L, and each of the water sprinkler guide plates C is constructed by means similar to the structure shown in FIGS. 2 and 3. The water sprinkler for an ice maker according to the present invention, which is independently arranged between each injection hole 4 (a) and between each guide lip/b, has the above-described structure and operation. Therefore, when attaching the sprinkler body to the ice-making plate, various experiments were carried out, and the angle of the joint between the holding protrusion of the sprinkler body and the sprinkling guide plate was adjusted so that the installation position would be at the optimal level for the flowing state of the ice-making water. After making the settings, each part can be manufactured, and any person can attach the sprinkler body to the ice-making plate with a single touch without requiring any adjustments, ensuring optimal ice-making at all times. It is possible to obtain a uniform flow of water, and it is possible to stably grow ice with a uniform thickness.
