Abstract

PROBLEM TO BE SOLVED: To reduce a falling sound of ice and prevent stored ice from being deformed by disposing a heat insulation member around an inner box in which ice is stored for insulating fresh air, and further disposing a sound absorbing member on a falling surface of ice on the side of the heat insulation member of the inner box. SOLUTION: A flat plane shaped sound absorbing member 7 is sticked to a falling surface of ice 5 of an inner box 2 on the side of the heat insulating member 3. As the sound absorbing member 7 there is used one having protrusions on its surface or one having through-holes vertically in its surface. The sound absorbing member 7 is disposed such that it has a slope from a center lower part toward opposite sides thereof and ice formed on the slope falls down along the slope. The ice 5 is made in an ice making apparatus 4, and the ice moves downward and is divided into small pieces with an ice cutting apparatus 6 which ice pieces are fallen down on a bottom of the inner box 2. Thereupon, the sound absorbing member 7 is sticked to the back surface of the inner box 2 so that a falling sound is restricted. Thus, sound vibration is suppressed by sticking the sound absorbing member to the falling surface of ice on the side of the heat insulating member of the inner box and hence a falling sound of the ice is reduced.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ice making machine for producing ice, and more particularly to a structure for reducing the falling sound of ice generated during the production.

[0002]

2. Description of the Related Art In recent years, there has been a problem that the falling sound of ice is large in an ice producing cycle of an ice making machine, and it has become essential to reduce this sound. As a conventional ice machine, Jiko 60
There is one disclosed in JP-A-11414.

Hereinafter, an example of the above-described conventional ice making machine will be described with reference to the drawings. FIG. 11 shows a conventional ice maker. In FIG. 11, reference numeral 1 denotes an outer box. 2 is the inner box,
Reference numeral 3 denotes a heat insulating material provided between the outer box 1 and the inner box 2. 4
Is an ice making device provided on the upper part of the inner box 2 to generate ice 5. 6
Is an ice breaking device which is arranged below the ice making device 4.

[0004] Regarding the ice making machine configured as described above,
The operation will be described below. First, ice 5 is generated by the ice making device 4. Next, the ice 5 moves downward, is divided into small pieces by the ice breaking device 6, and falls to the bottom of the inner box 2. The ice 5 is accumulated in the inner box 2 by repeating this cycle.

[0005]

However, in the above-mentioned conventional configuration, since the ice 5 dropped from the ice breaking device 6 directly collides with the bottom of the inner box 2, a loud noise is generated every time it falls. There were drawbacks.

An object of the present invention is to solve the conventional problems, and a first object of the present invention is to provide an ice making machine with reduced ice falling noise.

[0007] A second object is to prevent deformation of ice stored in ice. A third object is to improve the ability to take out the stored ice.

A fourth object is to improve the cleanability of the inside of the refrigerator.

[0009]

In order to achieve this object, an ice making machine according to the present invention comprises an inner box for storing ice and a heat insulating material disposed around the inner box for blocking outside air. An ice making device for generating ice, an ice breaking device for dividing the generated ice, and a sound absorbing member provided on the ice falling surface on the heat insulating material side of the inner box.

[0010] Further, the inner box has a structure in which a sound absorbing member is provided on the ice falling surface. Further, the sound absorbing member has a structure having projections on the surface.

Further, the sound absorbing member has a through hole in the vertical direction.

Further, the sound absorbing member has an inclined surface from the lower center to both side surfaces, and the sound absorbing member is arranged such that the generated ice falls on the inclined surface.

Further, instead of disposing the sound absorbing member directly at the bottom of the inner box, a structure is provided in which a storage box having an opening on the upper surface and a sound absorbing member provided on the inner surface is provided.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION In the ice making machine of the present invention, a sound absorbing member is arranged on the surface of the inner box where the ice falls on the side of the heat insulating material. Reduced.

Further, since the sound absorbing member is provided on the surface of the inner box on which the ice is dropped on the heat insulating material side, the dropped ice falls directly on the sound absorbing member and the falling sound is absorbed.

Further, since the surface of the sound absorbing member disposed on the falling surface of the ice on the side of the heat insulating material of the inner box has a projection, the accumulated ice has a small contact area with the sound absorbing member, and the ice is reduced. As it becomes difficult to melt, it becomes difficult for the melted water to come into contact with ice, thereby suppressing the occurrence of deformed ice.

Further, since the sound absorbing member arranged on the falling surface of the ice on the inner box has a through hole in a vertical direction, the ice melted from the ice on the sound absorbing member is immediately caused to flow to the lower surface. Prevents melted water from touching ice and suppresses the occurrence of deformed ice.

The sound absorbing member disposed on the ice falling surface inside the inner box has an inclined surface from the lower center to both side surfaces, and is arranged such that the generated ice falls on the inclined surface. As a result, the sound of falling ice is reduced, and the ice is collected and stored at one place, so that the ability to take out the ice is improved.

In addition, instead of disposing the sound absorbing member directly at the bottom of the inner box, a storage box having an opening on the upper surface and a sound absorbing member provided on the inner surface is provided. It falls on the sound absorbing member inside, and the generation of the falling sound is suppressed, and the storage box can be taken out.
