Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a fountain-type ice-making machine for spraying ice-making water from below into an ice-making small chamber or cell arranged with an opening facing downward, and in particular, such a fountain The present invention relates to a device for supplying ice-making water to a water tray that stores ice-making water to be spouted in a cell.

[Prior Art] In the ice making machine of the above-mentioned type, as can be understood from FIGS. 10 and 11, below a position-fixed ice making chamber 2 having a large number of cells 1 formed in a grid pattern, A water tray 4 is arranged so as to be rotatable around a fulcrum 3, and during the ice making cycle, the ice making water in the water tray 4 is pumped by a pump 5 to a fountain port 4b.
Fountain into cell 1 via the
It returns to the water tray 4 again via 4a, thus forming ice in the cell 1. When the ice in the cell 1 grows to a desired size, the ice making cycle is switched to the deicing cycle,
In order to drop the ice in the cell 1, hot gas is caused to flow through the evaporation pipe 6, and the water tray 4 is tilted in a direction away from the ice making chamber 2.

In this tilted state, ice may adhere not only to the surface 4c of the water tray 4 but also to the inside of the fountain port 4b and the return port 4a. Therefore, the water tray 4 is shown in FIG. When the ice making cycle is rotated upward to the position, the water tray 4 and the ice making chamber 2
Supports the water tray 4 because it causes various obstacles such as ice biting between and, and the ice making cycle progressing without spraying ice making water from a part of the fountain 4b. The bracket 7 is provided with a sprinkling pipe 8 to sprinkle water on the surface 4c of the tilted water tray 4 during the deicing cycle to remove the ice causing the obstacle and return the water to the return port 4a.
It is supplied to the water tray 4 through the water and used as ice making water for the next ice making cycle.

However, in general, when water is sent from the other end to the water sprinkling pipe 8 having one end closed and many discharge ports 8a, as shown in FIG. It is known that the water is discharged not at a right angle to the flow direction 8b but in a trajectory inclined toward the downstream side with respect to the flow direction 8b, and therefore a part of the surface 4c of the water tray 4 (see FIG. 10). It is also known that water is not sufficiently sprayed on the left side edge).

As a measure to eliminate inadequate water sprinkling, conventionally, the discharge port 8a at the end corresponding to the surface part of the water tray in which water sprinkling is insufficient is made horizontally longer than other ones to increase the flow rate or to increase the flow rate from the center to both ends Measures were taken to drain water toward it.

[Problems to be solved by the invention] However, when the discharge port is enlarged as in the former case,
Contrary to the intention, the water discharged from this large discharge port flows with a greater inclination than the water discharged from the other discharge ports, and tends to push the water of the other discharge ports toward the center of the water tray surface. There was a concern that the amount of water would become so large that it would flow over the weir plate 9 provided near the front end of the water tray 4 into the ice storage (not shown).

Also, when water is supplied from the center of the sprinkling pipe like the latter, the amount of water in the central part of the surface of the water tray becomes insufficient, or the amount of water at both ends becomes excessive, and it flows into the ice storage as in the former case. There was a concern that

Therefore, it is an object of the present invention to provide an ice making water supply device for a fountain type ice making machine, which allows water to flow evenly on the surface of a water tray.

[Problems to be Solved by the Invention] In order to achieve this object, an ice making water supply device according to the present invention has an ice making chamber having a cell arranged with an opening facing downward, and tiltable below the ice making chamber. In a fountain-type ice making machine, which comprises: a water tray disposed on the water tray, and water is sprayed from below onto the cell through the water tray, the water tray is disposed above the water tray along the width direction of the water tray. And a plurality of discharge ports are formed along the axis, and water is supplied to the inside of the spray nozzle across the plurality of discharge ports, and at least the discharge port on the most upstream side with respect to the water flow. And a next water outlet, the water guide member extending toward the surface of the water tray is provided, and the water from the most upstream discharge outlet collides with the water guide member. It is characterized in that the guide member is positioned.

[Operation] When water is made to flow inside the sprinkling pipe so as to cross the plurality of discharge ports, the water discharged from the discharge ports is inclined while flowing in the direction in which the water advances.

Therefore, if the present invention is not implemented, the position where the water discharged from the most upstream discharge port reaches the surface of the water tray is away from the edge of the water tray, and the water is evenly sprayed on the entire surface of the water tray. Not done.

However, as in the present invention, when a water guide member is disposed at least between the discharge port on the most upstream side with respect to the flow of water and the next discharge port, the water discharged from the discharge port on the most upstream side is the water. When it hits the guide member, it also flows into the area where water was not conventionally sprayed.

[Embodiment] Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals indicate the same or corresponding portions.

The water tray 4 has a water channel 11, a water reservoir 12, and a weir plate 9. The water channel 11 is sent by a pump 5 via a pipe 5a as indicated by an arrow. It is divided into a portion for supplying water inside the cells 1 through the fountain port 4b and a portion for returning water returning from each cell 1 to the water reservoir 12 through the return port 4a. Since it is disposed below the water tray 4, it is a residual water tank 13 that receives the residual water in the water tray 4 in the ice making cycle when the water tray 4 tilts downward during the deicing cycle. Further, the control plates 4d and 4e that prevent water from coming off from the surface 4c of the water tray 4 are disposed on both the left and right sides of the water tray 4 and vertically extend.

The water sprinkler or water supply pipe 14 of the ice making water supply device 10 has removable caps 14 at both ends for easy cleaning.
It has a and 14b, one end of the sprinkling pipe 14 extends through one regulating plate 4e, is supported by the regulating plate 4e, and is supported and guided relatively near the other regulating plate 4d. It penetrates through the plate (water guide member) 15 and is supported by this support / guide plate 15. The sprinkling pipe 14 has multiple outlets 14

The side surface 15c of the side guide portion 15b is preferably inclined with respect to the axial center of the sprinkling pipe 14 so that the tip end is closer to the regulation plate 4d.

Further, in FIG. 1, a water supply pipe 17 having a solenoid valve 16 is provided.
Is attached to the sprinkler pipe 14 from below, near the cap 14a, via a flexible U-shaped hose 18.

In the above ice making water supply device 10, the ice making water sent from the water supply pipe 17 to the sprinkling pipe 14 via the hose 18 is
From the outlets 14c-1, 14c-2, ...
Water is sprayed on each part to wash each part, but the regulation plate on the ice making water sending side
The water from the outlet 14c-1 closest to 4d hits the side surface 15c of the support / guide plate 15 and is reflected, otherwise effectively flowing towards the insufficient watering area 4f, resulting in Water is sprayed almost uniformly over the entire water tray.

In the first embodiment, the above-mentioned support / guide plate 15 is provided only between the two discharge ports 14c-1 and 14c-2 on the side of the regulating plate 4d, but it is provided between adjacent discharge ports or every other one. It may be provided in the.

Further, in the above-described first embodiment, one member 15 has both the function of supporting the water spray pipe 14 and the function of guiding water, but as shown in the modified embodiment of FIGS. 5 and 6, the water spray pipe 14 is used. Is formed in the regulation plates 4d and 4e in a substantially semi-circular recess, and the recess is provided as shown in the drawing. Water is guided by welding or sticking to the outer peripheral surface of the sprinkling pipe 14. The fin-shaped guide plate (water guide member) 20 may preferably be provided in an inclined shape as in the above-mentioned embodiment by an appropriate means, and this may be performed. In this case, the guide plate 20 terminates in the middle without engaging with the water tray surface 4c, and its shape is such that a portion where the water sprinkling pipe 14 is fitted is cut from a circular plate as shown in FIG. Although it is a crescent shape lacking, of course, other suitable shapes may be used, and the installation position of the guide plate 20 is not the one between the discharge ports, but the method described in connection with the first embodiment. Can be installed at.

Furthermore, in the above-mentioned first and second embodiments, the sprinkling pipe 14 is used.
Is supported by the water tray 4 and is configured to rotate integrally with the water tray 4, whereby the water spray pipe 14 is connected to the ice making mechanism frame 21.
Although the need for a member to be attached to (see FIGS. 7 and 10) has been eliminated, even if this configuration is desirable from the viewpoint of reducing manufacturing costs, it is not always an essential condition. And as shown in the third embodiment of FIG.
1 for supporting the water tray 4 as in the conventional example shown in FIGS. 10 and 11.
The water sprinkling pipe 14 may be inserted through the pair of brackets 7 and the water sprinkling pipe 14 may be supported by the bracket 7.

In this case, as shown in FIG. 8, the sprinkler pipe 14 in which the fixing plate 22 is fitted between the leftmost two outlets 14c-1 and 14c-2 is attached to the pair of brackets 7 and 7. A water guide plate (water guide member) 23 is attached to the fixed plate 22 side by an appropriate means such as a screw 24. The discharge port 14c-1 of the sprinkling pipe 14 is formed horizontally longer than the others (see FIG. 8).
The guide plate 23 is directly attached to the bracket 7 without using the fixing plate 22.
It may be fixed to.

The guide plate 23, as shown in FIG. 9A, has a mounting hole for the screw 24.
25, and a through hole 26 for inserting the sprinkling pipe 14,
As is clear from FIGS. 7 and 9A, the lower half portion thereof has a substantially triangular shape so that the tip is lowered toward the downstream of the flow of water from the discharge port. In addition, the guide plate 23 is
In the case of FIG. 9A, its front surface 23a drooped linearly from the top to the bottom, but as shown in FIG. 9C, the lower half of the guide plate 23 may be cut off along the slope 23b. Good.

In the third embodiment, the deicing cycle is entered, the water tray 4 is tilted in the direction away from the ice making chamber 2, and the sprinkler pipe 14 is moved.
From each of the outlets, water is sprayed toward the water dish surface 4c. The water discharged from the discharge port 14c-1 collides with the guide plate 23, but since the discharge port 14c-1 is relatively long, the streamline of the guide plate 23 of FIG. 9A is shown in FIGS. 8 and 9B. As indicated by the arrow, the streamline 14 'that originates near the left end of the major axis of the discharge port 14c-1 collides with the guide plate 23 at a position below the streamline 14 "that originates near the right end of the major axis. However, since the streamline 14 ″ is faster at the time of collision, the discharge port 14c-1
The water from the whole collides with and then spreads in a fan shape, part of which travels almost along the guide plate 23, and the rest of which is the front surface 23a.
And go around to the next discharge port 14c-2 side. However, this remaining portion is also due to the action of the guide plate 23, and the discharge port 14c-
Since the distance between 1 and 14c-2 is wider than the distance between the other outlets, it does not affect the flow of water that subsequently exits from outlet 14c-2.

Although the guide plate 23 in FIG. 9A has been described, the use of the guide plate in FIG. 9C not only achieves substantially the same action and effect, but also changes the slope and length of the slope 23b to change the bottom end. By changing the position, it is possible to change the condition of water injection onto the surface of the water tray as desired.

[Advantage of Invention] As described above, according to the present invention, since the water guide member is disposed at least between the discharge port on the most upstream side with respect to the flow of water and the next discharge port, the most upstream side is provided. The water discharged from the discharge port hits this water guide member, and water also flows to the area where water was not sufficiently sprinkled in the past. Therefore, various problems caused by insufficient water sprinkling were solved. (Since the residual ice on the surface, fountain and return port is eliminated and it is completely removed with a small amount of water, the amount of water used is reduced and the ice making cost is reduced.)
