[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an ice making machine for making ice cubes, and in particular, the invention relates to an ice making machine for making ice cubes, and in particular an ice making plate body made of a heat transfer material and a spacer made of a heat insulating material. The present invention relates to an improvement in a joining band for joining the ice making plates in an ice making machine equipped with ice making plates in which a large number of ice making compartments are partitioned by stacking ice making plates alternately in the vertical direction and joining them together.

(Prior art) As such an ice maker, for example,
One disclosed in Japanese Patent No. 190370 is known. That is, as shown in FIG. 1, there is an ice making plate main body 14 made of a heat transfer material such as aluminum with a plurality of vertical partition walls 12 protruding from the surface thereof, and an ice making plate main body 14 made of a heat transfer material such as aluminum with a plurality of vertical partition walls 12 protruding from the surface thereof, and an ice making plate main body 14 made of a heat transfer material such as aluminum with a plurality of vertical partition walls 12 protruding from the surface thereof. Partition wall 15
A spacer 17 made of a heat insulating material such as resin, which is provided with a horizontal partition wall 16 between adjacent vertical partition walls 15, 15, is stacked alternately in the vertical direction and joined together to form a front surface. The ice-making plate 10 has a large number of open ice-making chambers 18 divided into sections, and a cooling pipe 23 is heat-transferably attached to the surface of the ice-making plate body 14, and water flows down from the water spray tank 24 above. The ice-making capacity is made to freeze in each of the ice-making compartments 18, thereby preventing the ice produced in the upper and lower ice-making compartments 18, 18 from stacking up and down, and making it possible to freely change and select the ice-making capacity. be.

Conventionally, in order to configure the ice-making plate 10, the ice-making plate main body 14 and the spacer 17 are alternately stacked and combined to form an integral structure. As shown in FIG. 3, hook-shaped engaging portions 2 are provided at the upper and lower ends of the cylindrical portions 15a, 15a that protrude in the opposite direction.
By using a coupling band 27' having 7'a and 27'a and locking its upper and lower engaging parts 27'a and 27'a to the respective cylindrical parts 15a and 15a,
They are integrally coupled via the coupling band 27'.

Further, a water tank 28 is arranged below the ice-making plate 10 to receive water flowing down from the watering tank 24 and passing through each ice-making chamber 18 of the ice-making plate 10. In consideration of water flowing down along the coupling band 27', a water tank 2 is also placed below the coupling band 27'.
A part of 8 was located.

(Problems to be Solved by the Invention) However, in the conventional structure described above, the lower end of the coupling band 27' is formed into a hook-shaped engaging portion 27'a like the upper end, so that the band 2
At the lower end of the water flowing down through 7',
There is a problem in that the hook-like engaging portion 27'a protrudes to the side along the semicircularly curved lower surface as shown by the arrow in FIG. This water sometimes damaged the ice cubes that had accumulated in the ice storage compartment below.

Therefore, the present invention has been developed in view of this point, and its purpose is to improve the structure of the above-mentioned coupling band, especially the lower end, to ensure that the water flowing down the band is reliably drained into the water tank. The purpose is to contain the fall.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a solution to the problem, as shown in FIG. A guide piece 27b that hangs down toward a water tank 28 disposed below the ice-making plate 10 is configured to protrude from the lower end of the coupling band 27 for coupling the spacer 17 and the lowermost spacer 17. It is something.

(Function) With the above configuration, in the present invention, the watering tank 2
Even if some of the water from 4 flows down through the coupling band 27, the water is guided by a guide piece 27b at the lower end of the band 27 so that it flows down to the water tank 28 below. It is.

The guide piece 27b is integrally formed by folding a part of a leaf spring that constitutes the band 27. The coupling band 26 is also formed in the same shape as the band 27, and has engaging portions 26a, 26a at the upper and lower ends, and a water tank 22 at the lower end engaging portion 26a.
A guide piece 26b that hangs down toward 8 is integrally provided.

Therefore, in the above embodiment, the ice making plate 1
In each ice-making chamber 18 divided by the vertical partition wall 12 of the ice-making plate main body 14 and the vertical and horizontal partition walls 15 and 16 of the spacer 17, ice-making water flowing down from an upper watering tank 24 is provided. The ice-making chamber 1 is successively lowered along the upper and lower surfaces 16a, 16b of the horizontal partition wall 16 of the spacer 17 and the surface 11 of the ice-making plate main body 14.
However, since the ice making plate main body 14 is cooled by the cooling pipe 23 held in the recess 13 on the back side, the water flows down to the surface and left and right sides of the ice making plate main body 14 in the ice making chamber 18. Vertical partition wall 12
Ice cubes having a predetermined shape corresponding to the shape of the ice making chamber 18 are produced.

At this time, part of the water from the water tank 24 flows down through the connecting band 27 that connects the uppermost spacer 17 and the lowermost spacer 17, but this water is shown by the arrow in FIG. The band 27 is guided to flow down toward the water tank 28 by the guide piece 27b provided at the lower end of the band 27, and the water flows down from the lower end of the guide piece 27b into the water tank 28. will be definitely collected. The same can be said of water flowing down along the coupling band 26, and is reliably collected into the water tank 28 by the guide piece 26b. This prevents the ice cubes accumulated in the ice storage compartment from being damaged as in the conventional case. In addition, the ice maker of the above embodiment is configured so that a certain amount of water is initially supplied, and one cycle is completed by making ice until this water runs out.In this case, conventionally, ice is made by the amount of spilled water. Although the size of the ice cube that rises is small, this does not occur in this example, and the advantage is that the ice cube can be formed into a predetermined size.

Incidentally, the present invention is based on the cylindrical ice-making plate 1 as in the above embodiment.
Needless to say, the present invention can also be applied to ice-making plates having a rectangular parallelepiped shape.

(Effects of the invention) As explained above, according to the invention, in an ice making machine equipped with an ice making plate 10 formed by stacking the ice making plate main body 14 and the spacer 17 alternately and combining them into one, the ice making plate 10 top spacer 17 and bottom spacer 1
A guide piece 27b is provided at the lower end of the coupling band 27 that connects the band 27, and the water flowing down the band 27 is guided by the guide piece 27b at the lower end so that it flows down to the water tank 28 below. Therefore, water can be prevented from spilling out of the water tank 28 and can be reliably collected into the water tank 28, thereby preventing damage to the ice cubes in the ice storage compartment and preventing the resulting ice cubes from being small. It is possible to easily obtain ice cubes of a predetermined size without causing the ice cubes to become bulky.
