An ice-making plate e formed by forming a plurality of ice cube ice-making chambers d... (cells) at least in the vertical direction by ... is erected in a substantially vertical direction, and water supplied from above is passed through a horizontal partition plate c. upper surface c ₁ , outer end surface c ₂ , lower surface c ₃ and substrate a
A so-called vertical ice-making plate type is known in which ice is made in each ice-cube ice-making chamber d by wetting each surface along the surface a ₁ of the ice cube and flowing it along the surface.

However, in the conventional vertical ice making plate type, the horizontal partition plate c forming the ice cube making chamber d is made of a material with high heat conductivity such as copper, either integrally with the substrate a or separately, and Since the ice flows over the outer end surface _c2 of the horizontal partition plate c and flows from the upper ice cube making compartment d to the lower ice cube making compartment d, ice is also made on the outer end face _c2 of the horizontal partition plate c, During ice making, the ice s in the upper and lower ice cube ice making chambers d and d are connected as shown in the figure, and as a result, after the ice is made, a separate crushing means (cutting grid, crusher, etc.) crushes the ice into cubes. It was necessary to do so.

In addition, although ice removal after ice making is performed efficiently and quickly, the quality of ice in the ice storage chamber cannot be maintained at a good level.

The present invention was developed in view of the above, and it is possible to make ice cubes using the ice making plate itself during ice making in the vertical ice making plate type ice maker as described above, without requiring a separate crushing means. To provide an ice maker which eliminates the need for crushing after ice making, and which can quickly release ice cubes from the ice maker while maintaining good quality of ice in an ice storage chamber that has already been removed. That is.

That is, in the present invention, in particular, the ice-making plate A includes a substrate 1 made of a thermally conductive material and having the surface 1a as an ice-making surface.
a cooling pipe 4 thermally attached to the back surface of the substrate 1; At least a plurality of corners are formed in the vertical direction by a plurality of vertical partition plates 2 provided and horizontal partition plates 6 made of plastic protruding from the substrate surface 1a at intervals corresponding to the vertical width of an ice cube. The horizontal partition plate 6 is formed into a hollow body having a hollow part 6d for discharging water during ice-making, and a water supply tank for ice-breaking provided above the ice-making plate A. 13
The water flowing from the water tank 1 is passed through the hollow part 6d.
It is characterized by forming a waterway that flows down to 8.

By having the present invention configured in this way, when making ice,
The water sprinkled from the watering chamber 14 onto the ice-making plate A flows along the horizontal partition plate 6, and then flows through the substrate 1 and the vertical partition plate 2.
This makes it impossible to make ice on the horizontal partition plate 6 made of plastic, and prevents the ice cubes in the vertical ice cube compartments from joining together. Get an ice cube.

At the time of ice removal, hot gas flows through the cooling tube 4 thermally attached to the back surface of the substrate 1 of the ice making plate A, and the substrate 1
The vertical partition plate 2, which is continuous with this, is rapidly heated by the hot gas and the ice is removed from them, and at the time of the ice removal, a horizontal partition plate made of plastic is removed from the ice removal water supply tank 13. Water flows into the hollow body 6 to promote efficient ice removal with its auxiliary heat, and all of this water flows down to the water tank 18 without scattering in the middle of the hollow body or the flow channel.

Water is uniformly sprinkled onto the ice making plate A from the water sprinkling holes 14a, and water flows vertically through each ice cube making chamber 10 of the ice making plate A to make ice.

Next, the operation of the above embodiment will be explained.
When making ice cubes, first, a liquid refrigerant is made to flow through the cooling pipe 4, and the substrate surface 1a and the vertical partition plate 2 forming the ice cube ice making chamber 10 in the ice making plate main body B.
The plate walls 2a and 2b are cooled. On the other hand, water is uniformly sprinkled onto the upper circumferential surface of the spacer C ₁ at the uppermost end from the numerous water sprinkling holes 14a of the inner water sprinkling chamber 14 of the water tank D, and the upper surface of the horizontal partition plate 6 of the spacer C ₁ is sprayed uniformly. 6a, outer end surface 6c,
By sequentially wetting each surface from the bottom surface 6b to the substrate surface 1a of the ice making plate main body B, ice cubes are made in each ice cube making chamber 10. At this time, since the horizontal partition plate 6 facing the water flow direction is made of plastic, ice is not made on the outer end surface 6c of the horizontal partition plate 6, and therefore the upper and lower corners are The ice cubes in the ice cube compartments 10, 10 are not connected vertically, and ice cubes can be made independently in each ice cube compartment 10.

Therefore, after ice cubes are made, hot gas of the refrigerant is flowed through the cooling pipe 4 to cover the substrate surface 1a and the vertical partition plate 2.
By heating the plate walls 2a, 2b of the ice cubes, the ice cubes are independently released from each ice cube making chamber 10 and naturally fall into the ice storage chamber at the bottom. This eliminates the need for crushing. In particular, when ice is removed, water is flowed from the water sprinkling ports 13a of the outer ice-releasing water supply tank 13 of the water spray tank D to the hollow portion of each spacer C through the water pipes 16, and the water flows into the ice below the ice making plate A. All of the ice is used to promote ice removal without flowing into the storage room, making it easier to remove ice. Moreover, since the horizontal partition plate 6 of the cylindrical spacer C is made of plastic, ice cubes do not stick together during ice making, and the ice can be removed effectively by supplementary use of the heat of running water, which is effective. In addition, ice cube ice making room 1
The inner surface of the vertical partition plate 2 that constitutes the side wall of 0 (plate wall 2
a, 2b) and the inner surface of the horizontal partition plate 6 (upper and lower surfaces 6
By forming portions a and 6b) into tapered surfaces that widen outward, the above-mentioned ice removal can be carried out even more easily.

In the above embodiment, the cylindrical vertical ice plate A
Although the case has been described, the present invention is not limited to this, and the ice-making plate may be plate-shaped, and the same can be said if the above-mentioned cylindrical plate is expanded to be plate-shaped.

As explained above, according to the present invention, in a vertical ice making plate type ice making machine having a plurality of ice cube making chambers at least in the vertical direction, the horizontal partition plate constituting the ice cube making chamber is made of plastic. Since ice cubes can be made independently by the ice making plate itself, a separate crushing means for forming ice cubes is not required, and thus the structure can be simplified and ice cube making can be made more efficiently.

In addition, the horizontal partition plate is a hollow body having a hollow part for water to flow during ice removal, and is configured to form a flow channel through which water from the ice release water supply tank flows down to the water tank through the hollow part. Therefore, ice cubes can be efficiently and quickly removed after ice cube production using supplementary heat from running water, while maintaining good quality of the ice in the ice storage chamber that has already been removed.
