Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a drum type ice making machine, and more particularly to a drum type ice making machine in which powdered ice is produced together with ice pieces during ice making.
[0002]
[Prior art]
A conventional drum type ice making machine 1 will be described with reference to FIG. The drum type ice making machine 1 includes a cylindrical drum 3 in an ice making tank 2, and ice making water is filled between the ice making tank 2 and the cylindrical drum 3 to a predetermined water level. The cylindrical drum 3 rotates while being cooled by an evaporator (not shown). As a result, layered ice grows on the surface of the cylindrical drum 3, and the ice is peeled off by the cutter 4 fixed to the ice making tank 2, becomes a scale, slides down the slope 5, and passes through the chute 6 to store ice. It is a mechanism to enter the warehouse.
[0003]
[Problems to be solved by the invention]
By the way, when the ice is peeled off by the cutter 4, powdery scrap ice is produced together with the scaly ice pieces. As shown in FIG. 7, the scaly ice pieces move on the parabola as indicated by the arrow a. On the other hand, the powdered ice accumulates to some extent, falls almost directly from the end of the slope 5 as shown by the arrow b, and adheres to the wall surface 6 a of the chute 6. The powdered ice thus attached becomes water droplets with the passage of time and falls to the ice storage along the chute wall surface 6a. Therefore, this water droplet melts the ice in the ice storage, and as a result, there is a possibility of causing arching in the ice storage.
The present invention was made to solve such problems, and an object of the present invention is to provide a drum type ice making machine capable of preventing powdered ice and melted water thereof from flowing into an ice storage. To do.
[0004]

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
With reference to FIGS. 1-3, the outline of the drum type ice making machine 11 which concerns on embodiment of this invention is demonstrated. The drum type ice making machine 11 includes a cylindrical drum 13 in an ice making tank 12, and ice making water is filled between the ice making tank 12 and the cylindrical drum 13 to a predetermined water level. The cylindrical drum 13 is driven to rotate in the direction indicated by the broken line arrow in FIG. 1 and incorporates an evaporator for cooling the drum 13 body. On the other hand, a cutter 14 for peeling ice is firmly fixed to the ice making tank 12, and a metal blade having sufficient strength to peel off the ice is used as the cutter 14. Further, a slope 15 for guiding ice is fixed to the cutter 14 so as not to make a boundary with the cutter 14, so that the ice moves without being caught by the boundary between the cutter 14 and the slope 15. Further, guards 16 are provided on both sides of the slope 15 so as to be fixed to the ice making tank 12 and regulate the direction of the ice. Since ice always adheres to the slope 15 and the guard 16, the ice A resin material having a low heat transfer property is used so as not to dissolve. Further, a chute 17 for guiding ice falling from the slope 15 to an ice storage (not shown) is fixed to the ice making tank 12. The exit of the chute 17 extends outside the machine room, and the ice falling in the chute 17 enters the ice storage as it is. In addition, a gap 18 is provided between the wall surfaces 17a and 17b of the chute 17 on the ice making tank 12 side for collecting powdered ice or melted water generated when the ice is peeled off. Further, a drain pan 19 for receiving water droplets collected by the gap 18 is provided below the ice making tank 12.
As shown in FIG. 4, the gap 18 serving as the powder ice collecting means divides the wall surface on the ice making tank 12 side of the chute 17 into two vertically, and the upper divided wall surface 17a is divided from the lower wall surface 17b. Is also provided by offsetting to the ice making tank 12 side. In addition, a guide 20 is provided at the upper portion of the lower wall surface 17 b, that is, the defining portion of the gap 18, and guides the powdered ice or its molten water to a predetermined location. The guide 20 is inclined toward the outside of the chute 17. It has a slope shape that extends downward.
[0006]
Next, the operation of the drum type ice making machine 11 having the above configuration will be described. When the cylindrical drum 13 is cooled by operating the refrigerant circuit, layered ice grows on the surface of the drum 13 below the surface of the ice making water filled in the ice making tank 12. This ice moves onto the water surface by the rotation of the cylindrical drum 13 and is supercooled to become dry ice containing no moisture. Then, the ice is peeled off by the cutter 14 to become thin scale-like ice, and is pushed out along the slope 15 toward the chute 17 by the newly peeled and generated ice. Therefore, the ice slides down the slope 15 while the direction is regulated by the guard 16, passes through the chute 17 and enters the ice storage.
When the ice is peeled off by the cutter 14, scale-like ice is generated, and at the same time, powdery scrap ice is generated from cracks at the time of peeling. As shown in FIG. 1, the scaly ice pieces fall on a parabola as indicated by arrow a and enter the ice storage as it is. At this time, since the chute 17 has a sufficient width and guards 16 are provided on both sides of the slope 15 to restrict the traveling direction of ice, the scaly ice pieces do not collide with each wall surface of the chute 17. Absent. On the other hand, since the powdered ice does not slide on the slope 15 and accumulates to a certain extent and falls at a stroke, it falls almost directly from the tip of the slope 15 as indicated by the arrow b, and falls on the wall surface 17a of the chute 17 on the ice making tank 12 side. Adhere to. The powdered ice adhering in this way is melted with the passage of time and becomes water droplets, and is discharged to the outside of the chute 17 through the gap 18 provided between the upper wall surface 17a and the lower wall surface 17b. Drain pan 19 is drained. Further, even if powdered ice accumulates in the gap 18, not only does the melted water not enter the ice storage through the wall surface 17 b, but water droplets discharged from the chute 17 to the outside of the chute 17 will not leak. It becomes possible to drain into the drain pan 19.
As described above, since the wall surface of the chute 17 on the ice making tank 12 side is offset and the gap 18 is provided between the upper wall surface 17a and the lower wall surface 17b which are divided in this way, the powdered ice or its melting Water can be prevented from flowing into the ice storage, and as a result, arching in the ice storage can be prevented. In addition, the guide 20 provided on the lower wall surface 17b can more reliably guide the powdered ice or the molten water thereof to the outside of the chute.
[0007]
Note that the present invention is not limited to the above-described embodiment, and various modifications can be made. That is, instead of the guide 20 provided on the lower wall surface 17b of the chute 17 in the above-described embodiment, a guide 30 having a fold line 30a (or a groove) as shown in FIG. As shown in (b), a guide 40 having wall plates 40a on both sides, and a guide which is not shown, but has wall plates on both sides, and the interval between the wall plates becomes narrower toward the falling end. Etc., and water droplets may be more reliably guided to a desired place. Moreover, as shown in FIG. 6, you may use the guide 50 which the upper end protrudes into the inside of the chute | shoot 17. In this case, it becomes easy to collect | recover powdered ice. Further, instead of guiding the water droplets from the gap 18 to the drain pan 19, it is also possible to guide the water to an apparatus that can be reused for ice making.
