DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric ice crusher for breaking ice blocks formed in a freezer or the like into small pieces of ice.

[0002]

2. Description of the Related Art An electric ice crusher disclosed in Japanese Patent Application Laid-Open No. 2-130370 is known. This ice crusher has a bottomed cylindrical case with an upper end opened, a lid for opening and closing the upper end opening of the case, and a rotating shaft provided through the bottom wall of the case and rotated by the power of an electric motor. An ice block input cylinder which is disposed in the case and has upper and lower ends opened, and is attached to the rotating shaft to form an ice piece exit gap between the lower end of the input cylinder and
And a crushed body having a crushing projection on the upper surface.

When the electric motor is operated in this ice crusher, the crushing projection of the crushed body that rotates together with the rotating shaft collides with the ice blocks thrown into the ice block charging cylinder, and crushes them to form ice chips (crush ice). The ice chips smaller than the ice chip outlet gap can be discharged through the gap to the outside of the ice block charging cylinder by the centrifugal force of the crushed body or the like, and can be collected at the bottom of the case. When obtaining the required amount of ice pieces produced in this manner, the above-described operation is repeated by repeatedly supplying ice blocks into the ice block charging cylinder with the attachment and detachment of the lid.

[0004]

However, in the ice crusher described in the above-mentioned publication, since the ice block storage portion of the ice block charging cylinder has a cylindrical structure whose diameter does not change, the ice crushed upward by the crushing projections. Pieces easily adhere to the inner surface of the lid through the upper end opening of the ice block charging cylinder. Therefore, when the lid is attached and detached to replenish the ice blocks, there is a problem that ice pieces adhered to the inner surface of the lid fall and wet the surroundings, and the amount attached to the inner surface of the lid is wasted, and There is a problem that the yield of one piece is not good. Also,
In the ice crusher described in the above publication, since the diameter of the upper end opening of the ice block insertion cylinder is relatively large, it is possible to erroneously insert a hand into the ice block insertion cylinder in the open state. However, if the hand is erroneously inserted into the ice block loading cylinder as described above in a state where the rotation of the crushed body by the electric motor is continued, there is a possibility that the ice block splashed on the hand may collide. SUMMARY OF THE INVENTION An object of the present invention is to provide an ice crusher that can produce ice pieces with a good yield, can reduce the amount of wetting around, and can ensure the safety of work.

[0005]

In order to achieve the above object, an ice crusher according to the present invention is arranged such that an upper part of an ice block charging cylinder disposed on a partition in a case is placed inside the ice block charging cylinder. And formed in an annular ice return portion surrounding the inlet formed by the upper end opening of the ice block input cylinder.

[0006]

According to the present invention, the upper portion of the ice block input cylinder is formed.
Since the annular ice return portion is protruded toward the inside of the charging cylinder, the diameter of the charging port can be reduced. for that reason,
This makes it difficult to accidentally insert a hand through the input port into the ice block input cylinder when inputting an ice block. In addition, since the input port has a small diameter, ice pieces splashed upward by the crushed body can be less likely to pass directly through the input port. In addition, as described above, since the ice return portion is protruded toward the inside of the ice block input cylinder, the ice block or ice pieces flipped upward by the crushed body out of the upper inner periphery of the ice block input box. What is hit obliquely upward on the surface can be bounced downward at the ice turning part.
In addition, the circular ice return forms the upper part of the ice block loading cylinder.
Since it is not at the middle position of this loading cylinder in the height direction, the loading port
The circular ice return is in the way of the ice block that has been thrown through
Ice blocks can be reliably supplied to the crushed body side
You.

Next, a procedure for making crash ice will be described. First, as shown in FIG. 15, the ice piece receiving container 91 is placed below the ice piece taking-out opening body 51, and the lid 75 is removed. An appropriate number is supplied through the input port 70. Next, after covering the lid 75 as shown in FIG.
2 is pressed downward as shown in FIG. 2 to fix the ice block loading cylinder 61 and turn on the switch 22 to start the electric motor 12.

Then, while the lid 75 is being pushed by hand, the crushed body 8 connected to the rotating shaft 13 of the electric motor 12 is
1 is rotated at a high speed, so that the crushing projections 84, 85
Repeatedly hits the ice block. Due to this collision, the ice blocks are crushed one after another into small pieces of ice (crash ice),
The disk portion 82 is moved outward by the centrifugal force and the crushing projections 84 and 85. And the ice block loading cylinder 6
The crushed ice, which has become smaller than the gap G between the lower end of the first piece 1 and the disk portion 82, is supplied to the ice piece passage 87 through the gap G, and then moves through the ice piece passage 87. The ice pieces are moved by the ice pieces 86, and are discharged from the ice piece outlet 37 to the ice piece take-out passage body 45 in a vigorous manner. Therefore, the crushed ice passes through the ice piece take-out opening 51 from the ice piece passage 87, and the ice-piece receiving container 9 arranged below the opening 51.
One after another, it is taken out one after another.

Therefore, it is not necessary to take out the crushed ice produced in the case 31 from the case 31 each time, so that it is easy to use.

When a large amount of ice chips are to be produced, after the above-mentioned ice chips are taken out, the lid 75 is opened to stop the operation of the electric motor 12, and then the ice blocks are again thrown in. Just repeat. In addition, in the charging of the ice block,
The upper part of the ice block charging cylinder 61 is formed by an annular ice return section 63.
The inlet 70 provided in the center of the
The ice turner 63 interferes with the ice blocks thrown through
Therefore, the ice blocks can be surely crushed 81
Can be supplied to the side.

By the way, in the process of obtaining the crushed ice as described above, the ice blocks or ice pieces are splashed upward by the crushing projections 84 and 85 in the ice block charging cylinder 61. However, the ice block input cylinder 61 is provided with an ice return portion 62 protruding inward at the upper portion thereof, and the opening area of the input port 70 is reduced by the overhang, so that the input port 70 can be placed without hitting the ice block input cylinder 61. The amount of ice chips passing directly can be reduced. In addition, as shown by the arrow D in FIG. 2, ice pieces or pieces of ice that have been flipped upward and that have hit the inner peripheral surface of the upper portion of the ice block charging cylinder 61 and have been bounced obliquely upward are subjected to the ice return section 63. Can bounce down. Therefore, through the inlet 70, the lid 7
5 can reduce the amount of ice chips attached to the inner surface. Moreover,
In the present embodiment, since the ice returning portion 63 has the downward portion 71, the ice block or the ice piece that has hit the upper inner peripheral surface of the ice block input cylinder 61 and is obliquely upwardly bounced passes through the input port 70. High shielding effect.

For these reasons, the amount of ice chips unnecessarily attached to the inner surface of the cover 75 can be reduced, the yield of the formed ice chips can be improved, and the cover 7 for replenishing ice blocks can be obtained.
With the attachment / detachment of the cover 5, the surroundings can be less likely to be wet by the ice pieces attached to the inner surface of the lid 75.

As described above, the ice return portion 63 for reducing the adhesion of ice pieces to the lid 75 is provided so as to protrude inside the ice block charging cylinder 61 as described above.
The height of 3 itself does not need much. Therefore, the height of the ice block charging cylinder 61 can be reduced. In addition, the ice turning part 63
Is wrapped inward from its periphery toward the inlet 70, so that it can guide ice blocks or pieces of ice along its inner surface and quickly return to the crushed body 81 side, so that the ice blocks can crash. The processing time for making ice can be shortened.

Further, by providing the ice return portion 63 as described above, the diameter of the input port 70 of the ice block input cylinder 61 can be reduced. It can make it difficult to reach out by mistake. Therefore, when the switch 22 is turned off with the removal of the lid 75 and the ice block is supplied to the ice block charging cylinder 61 under the condition that the rotation axis of the electric motor 12 is rotating by inertia, the crushed The ice block bounced off at 81 does not hit the hand, and the ice block can be supplied safely.

In the structure of the present embodiment, when making the crushed ice as described above, in order to obtain the crushed ice having a small roughness, the first concave portion 65 of the ice chunk charging cylinder 61 is connected to the operation rod cover 57. And the charging cylinder 61 is
The first procedure is to be carried out after storing in the first set position. In this case, as shown in FIG. 11, the ice piece passing portion 69 of the ice chunk charging cylinder 61 is displaced from the ice piece outlet 37 and is positioned so as not to face, and the lower cylindrical portion 68 is connected to the ice piece outlet 37. It opposes and covers a part (upper part).
Therefore, the size of the crushed ice passing through the ice piece outlet 37 is limited to the size of the gap G or less.

In order to obtain crushed ice having a large roughness, the second concave portion 66 of the ice chunk charging cylinder 61 is fitted to the operation rod cover portion 57, and this charging cylinder 61 is connected to the second rod of the case 31.
And the above-described procedure may be performed. In this case, as shown in FIG.
Ice piece passing section 69 is located opposite to the ice piece exit 37,
The whole outlet 37 is opened. Therefore, the disk portion 8 of the ice piece outlet 37 is not restricted by the gap G.
Crush ice of size of opening of upper part than 2,
That is, an ice piece larger than the ice piece passing through the gap G can be passed through the ice piece outlet 37 and taken out.

The present invention is not limited to the above embodiment. For example, the body housing the motor and the case may be integrated. Further, the present invention does not include an ice piece outlet, an ice piece taking-out passage, and the like.
As described in Japanese Patent Application Laid-Open Publication No. H10-209, the present invention can also be implemented in an ice crusher having a configuration in which ice pieces cannot be automatically removed. Further, in the present invention, the downward bent portion of the ice return portion may be omitted.

[0042]

As described above, the ice crusher according to the present invention is characterized in that the upper part of the ice block charging cylinder disposed on the partition wall in the case is projected toward the inside of the ice block charging cylinder so as to project the ice block. Because it is characterized by a configuration formed by an annular ice return part surrounding the input port consisting of the upper end opening of the input cylinder,
The ice block thrown into the ice block loading cylinder is trapped in the
In addition to preventing the hand from being hung and making it difficult for a hand to be accidentally inserted into the ice block input cylinder through the input port when the ice block is input into the ice block input cylinder, it is possible to secure operational safety. The ice return portion not only reduces the amount of the ice pieces splashed upward by the crushed body and directly passes through the input port, but also the ice blocks or the ice pieces of the ice pieces flipped upward. What hits the upper inner peripheral surface and is bounced obliquely upward can be bounced downward, so that ice pieces can be produced with good yield and the surroundings can be prevented from getting wet with the attachment and detachment of the lid.
