Description

[Detailed description of the invention] This invention relates to an improvement of the ice-making plate in an ice-making machine.
In particular, in an ice-making board that creates a large number of ice-making compartments by alternately stacking the ice-making board body made of a heat-conducting material and the spacer made of a heat-insulating material, the ice cubes in each ice-making compartment are This aims to promote ice formation and ice removal.

By the way, by stacking the ice-making plate main body made of heat-transfer material and the spacer made of heat-insulating material alternately, a large number of ice-making compartments are created on the surface, and cooling pipes are installed on the back surface of the main body for heat transfer. The ice-making capacity of the ice-making plate configured to be held can be freely increased or decreased by appropriately selecting the stacked number of the main body and the spacer, and a spacer made of a heat-insulating material is generated in each ice-making chamber. This has the advantage of preventing ice cubes from forming in a row and forming completely separated ice cubes.
(See No. 27351).

However, since the spacer does not have a heat transfer function, it takes some time to generate ice, and it is especially difficult to separate the ice cubes generated from each ice making chamber by supplying hot gas to the cooling pipe. It takes a long time.

The purpose of this invention is to address the above-mentioned problems in ice-making plates that are constructed by stacking the ice-making plate body made of a heat-conducting material and the spacers made of a heat-insulating material alternately. By supplying water for ice removal to the ice cubes, the ice cubes generated in each ice making chamber are accelerated to ice cubes, and the water cooled by this ice removal is then used as water for ice making. This also reduces time.

As a distant relative of this purpose, in the present invention, the ice making plate main body made of heat transfer material and the spacer made of heat insulating material are stacked alternately,
In an ice-making plate which has a large number of ice-making compartments (on the front surface) and which has cooling pipes thermally held on the back surface of the main body by vertical and horizontal partition walls protruding between the main body and the spacer, each of the above-mentioned spacers is By forming the spacers hollow and sequentially connecting the hollow parts of each spacer, a series of ice-release water passages were formed.This allowed the hot gas passing through the cooling pipes to flow inside the spacers during ice-release. The water passing through the ice cube also melts the surface of the ice cubes in the ice making chamber, promoting ice removal. As mentioned above, the ice cubes are cooled by melting the surface of the ice cubes at the time of ice removal, so the ice cubes quickly freeze inside the ice making chamber.

Hereinafter, the present invention will be explained based on an embodiment of a cylindrical ice making machine shown in the figure. In FIG. An ice-making plate main body 4 having a plurality of vertical partition walls 2 protruding from each other at width intervals of

A large number of ice-making compartments 8 are constructed in which the ice-making plate bodies 4 are alternately stacked so as to be sandwiched therebetween, and each of the partition walls 2, 5, and 6 opens one side of the ice-making compartments 8.

Here, the ice making plate main body 4 is formed by cutting a drawn material made of a heat transfer material such as aluminum into a dimension corresponding to the vertical width of the ice cube to be manufactured, and each vertical partition wall 2 in the main body 4 is A heat insulating member 9 is attached to each tip.

Further, the spacer 7 is formed of a heat insulating material such as synthetic resin,
By joining the upper member 7' and the lower member 7'', which have the same shape and are concave on the inside, at their end faces as shown in FIG. The two predetermined vertical partition walls 5 have an open cylindrical part 5 at the tip end which communicates with the hollow part A.
a is provided, and a columnar body 5 is provided at the tip of the other vertical partition wall 5.
b is provided protrudingly.

Further, in FIG. 1, 10 is a water supply pipe connected to the cylindrical portion 5a of a predetermined vertical partition wall 5 of the spacer 7 located at the uppermost stage, and 11 is a predetermined vertical partition of the spacer 7 located at the lowermost stage. A drainage pipe 12 is connected to a cylindrical part (not shown) in the wall, and a U-shaped communication pipe 12 connects the corresponding cylindrical parts 5a, 5a in the upper and lower spacers 7, 7. As shown in the figure, a series of de-icing water passages B are formed from the water supply pipe 10, passing through the hollow portions A of each spacer 7 in sequence and reaching the drain pipe 11.

Reference numeral 13 denotes a meandering cooling pipe which is thermally fitted and held in the recess 3 provided on the back surface of the ice-making plate main body 4, and its both ends 1
3a and 13a are connected to a refrigerant circulation system (not shown), and 14 is an annular water tank disposed above the ice making plate 1, and is provided on the side thereof. A pump (
The water tank 14 is provided with an inlet 15a for ice-making water that is pumped under pressure (not shown) and a drain port 15b for discharging excess water.
4a is bored.

Further, a semi-cylindrical projection 14b is provided at a predetermined position on the side surface of the water tank 14, and the projection 14b and the spacer 7 at the lowermost stage are connected to each other.
The water sprinkling tank 14 is coupled to the ice-making plate 1 by locking the upper and lower ends of a coupling band 17 formed of a spring material to the columnar body 5b, respectively;
In addition, each ice-making plate main body 4 and spacer 7 that constitute the ice-making plate 1 are as follows:
Cylindrical portions 5a, 5 in the uppermost and lowermost spacers 7, 7
On the coupling band 18 formed of the same spring material as in a,
The lower end portions are respectively locked so that they are integrated.

Further 19. 20. Reference numeral 21 denotes a member for fixing the unit of the ice-making plate 1 and water tank 14, which are combined as described above, in a hanging manner within the case (not shown) of the ice-making machine;
Reference numeral 9 indicates a support member that supports the ice-making plate 9 from below, 20 indicates a hanging member constructed within the case, and 21 indicates both members 19.2.

According to the above configuration, each of the ice making chambers 8, which are separated by the vertical partition wall 2 of the ice making plate main body 4 and the vertical and horizontal partition walls 5.6 of the spacer 7 in the ice making plate 1, is provided with water from the upper watering tank 14. The ice-making water flowing down passes along the surface of the horizontal partition wall 6 of the spacer 7 and the surface of the ice-making plate main body 4, and flows into the lower chamber in sequence. 3, the water is frozen in each ice making chamber 8, thereby forming ice cubes corresponding to the shape of the chamber 8.

However, when ice cubes are placed in each ice making compartment 8 as described above,
By supplying hot gas to the cooling pipe 13, the surface of the ice cubes in each ice making chamber 8 is heated and melted through the ice making plate body 4, thereby separating the ice cubes from the ice making chamber 8. In this case, since the spacer 7 that constitutes the ice making chamber 8 together with the main body 4 is hollow, and a passage B for ice removal water is formed in the hollow portion A, the ice cubes in the ice making chamber 8 are The surface of the ice cube that is in contact with the spacer 7 is also melted by the water passing through the passage B, and in the end, the surface of the ice cube is heated and melted from all sides of the ice making chamber 8. This promotes ice removal and shortens the ice removal time.

Furthermore, the ice-release water that passes through the spacer 7 and flows out from the drain pipe 11 to the lower water storage tank 16 is reversed when the surface of the ice cubes is melted in the ice making chamber 8. When this water is cooled from the ice cubes and supplied from the water storage tank 16 to the ice making plate 1 via the upper water spray tank 14 by a pump (not shown), each ice making compartment 8 is cooled because it has already been precooled. In this way, the ice-making time can be shortened.

As described above, the present invention creates a large number of ice-making chambers on the front surface by stacking the ice-making board body made of a heat-transfer material and the spacer made of a heat-insulating material, and also creates ice-making compartments on the back side of the body. In the ice-making plate that holds the tubes in a heat-conductive manner, the spacers are formed in a hollow shape, and the hollow portions of the spacers are successively connected to form a series of ice-removing water passages. When ice cubes raw-hulled in each ice making chamber are released, the surface of the ice cubes is melted by hot gas supplied into the cooling pipe as well as ice for ice removal supplied to the passage, Furthermore, when this ice-releasing water is then supplied to the ice-making plates as water for ice-making, several of the ice-making plates are cooled in advance, so they are quickly frozen in each ice-making chamber. As a result, the ice-making time and the ice-making time are shortened, and the ice-making ability of the ice-making machine is improved.
