Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a water sprinkling device installed in an ice making machine to generate sheet ice on the lower surface of an ice making plate.

BACKGROUND OF THE INVENTION A conventional water sprinkling device for an ice maker will be described below with reference to the drawings.

Fig. 4 is a sectional view of a conventional ice maker, Fig. 5 is a sectional view of a water sprinkling device of a conventional ice maker, and Fig. 6 shows the flow of ice-making water introduced into the water storage section in the water sprinkling device of a conventional ice maker. FIG. In FIG. 4, reference numeral 1 denotes the main body of the ice maker, which is equipped with a water sprinkler 2 inside the refrigerator. A water solenoid valve 3 that is connected to the water supply and introduces tap water is arranged at the rear of the refrigerator, and a tank 4 that stores this tap water is connected to the water solenoid valve 3.
It is provided at the bottom. A pump 5 for delivering ice-making water from the tank 4 is provided in the tank 4, and a hose 6 is provided for guiding the ice-making water from the pump 5. This hose 6 is branched at a cheese 7 in the middle and connected to cylindrical portions 8 at both ends of the water sprinkler 2 . The water sprinkler device 2 is provided on the upper end side of the ice-making plate 9. The ice-making plate 9 is a flat plate installed at an angle inside the refrigerator, has an evaporator 10 of a refrigeration cycle on its upper surface, and forms ice cubes by flowing ice-making water on its lower surface.

The watering device 2 has a cylindrical portion 8 to which hoses 6 are connected on both sides.
and has a predetermined distance 11 from the lower surface of the ice making plate 9.
The guide part 11 extending so as to have a shape a and the water storage part 12 communicating with the guide part were integrally formed.

Problems to be Solved by the Invention Therefore, in this configuration, the ice-making water diverted from the pump 5 by the cheese 7 is introduced into the water storage part 12 from the cylinder parts 8 at both ends of the water sprinkler 2, but is not introduced. The ice-making water is stored in the water storage section 1 as shown by the arrow in Figure 6.
The ice-making water that collides with the center of the guide portion 2 and is blocked flows out toward the guide portion 11. The ice-making water that was flowing toward the center of the water storage section 12 within the water storage section 12 collides with the center of the water storage section 12, and the water surface of the ice-making water rises around the center of the water storage section 12.
The force that forces the ice-making water inside to flow out toward the guide section 11 becomes stronger as it moves toward the center of the water storage section 12. Therefore, as the water moves toward the center of the water storage section 12, the amount of water flowing toward the guide section 11 increases, and a uniform flow is not obtained, so that the sheet ice produced by the ice making plate 9 becomes uneven.

What is particularly important is that if the flow rate of the ice-making water fluctuates, the ice-making water will not be guided by the ice-making plate 9 and will fall directly, leading to product defects.

Therefore, the present invention provides a water sprinkling device that can maintain a constant flow rate in a water storage section and provide a uniform flow of water.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention forms the inner surface of the sloped upper end side of the ice-making plate in the water storage part so as to protrude into the water storage part as it goes toward the center of the water storage part. It is.

Function: In the present invention, the inner surface of the sloped upper end of the ice-making plate in the water storage part is formed so as to protrude into the water storage part as it goes toward the center of the water storage part. The cross-section of the ice-making water flow path has become smaller, and the ice-making water that used to flow toward the center of the water storage section has become smaller, causing the water surface of the ice-making water to swell and flow away from the center of the water storage section. The amount of outflow will increase compared to before. Moreover, the ice-making water flowing inside the water storage part toward the center of the water storage part has a flow direction closer to the guide part due to the inner surface of the sloped upper end of the ice-making plate in the water storage part, so this effect also causes the ice-making water to flow toward the center of the water storage part. The amount of outflow from areas far away from the guide portion to the guide section increases compared to the conventional method. Therefore, the amount of water that flows out from the center of the water storage section to the guide section increases compared to the conventional water sprinkler system, which had a relatively small amount of flow from the center of the water storage section to the guide section. Therefore, the amount of water flowing out from the water storage section toward the guide section is equalized, and a uniform flow of water is obtained.

Embodiment An embodiment of the present invention is shown below in Figs. 1, 2, and 3.
This will be explained with reference to the drawings, but since the only difference is the structure of the sprinkler device, this point will be explained in detail.

In the figure, reference numeral 13 denotes an elongated water sprinkler device fixed to the lower surface of the sloped upper end of the ice-making plate 9 with screws 14. The water sprinkling device 13 includes a cylindrical portion 15 to which a hose is connected, a guide portion 17 extending so as to have a predetermined distance 16 from the lower surface of the ice-making plate 9, and guiding ice-making water to the ice-making plate 9.
The water storage part 18 is composed of a water storage part 18 into which ice-making water is introduced from cylinder parts 15 provided at both left and right ends.
The inner surface 19 of the ice-making plate 9 on the sloped upper end side of the water storage portion 18 is formed to protrude into the water storage portion 18 as it goes toward the center portion 20 .

In this embodiment, the inner surface of the ice-making plate 9 on the sloped upper end side of the water storage section 18 is formed so as to protrude into the water storage section 18 as it goes toward the center of the water storage section 18, as shown in FIGS. 2 and 3. As in, water storage section 18
The flow cross section of the ice making water in the water storage section 18 becomes smaller as it goes towards the center of the water storage section 18, and the ice making water that was flowing towards the center of the water storage section 18 becomes smaller due to the decrease in the flow path cross section. Water surface rises and water storage part 1
The amount of outflow to the guide portion 17 from a portion away from the center of the guide portion 8 is increased compared to the conventional case. Moreover, as shown in FIG. 3, the ice-making water flowing inside the water storage section 18 toward the center of the water storage section 18 is directed toward the guide section 17 due to the inner surface of the sloped upper end of the ice-making plate 9 in the water storage section 18. Therefore, due to this influence as well, the amount of outflow to the guide portion 17 from a portion away from the center of the water storage portion 18 increases compared to the conventional case. Therefore,
The amount of outflow to the guide part 17 from a part away from the center of the water storage part 18 increases compared to the conventional water sprinkler device, which had a relatively small amount of outflow to the guide part from a part away from the center of the water storage part 18. , the ice-making water in the water storage section 18 is transferred to the water storage section 18 as shown by the arrow in FIG.
The amount of water flowing from the guide portion 17 toward the guide portion 17 is equalized, and a uniform flow of water is obtained.

Effects of the invention As is clear from the above explanation, in the present invention, the inner surface of the sloped upper end side of the ice-making plate in the water storage part is formed so as to protrude into the water storage part as it goes toward the center of the water storage part. Compared to conventional sprinklers, which had a small amount of outflow from the center of the water storage section to the guide section, the amount of outflow from the center of the water storage section to the guide section is increased, and the amount of flow from the water storage section to the guide section is increased. The amount of water flowing toward is equalized, resulting in a uniform flow of water.
