Abstract

PURPOSE:To cause ices in any ice block passages to be kept at a substantial constant compressed condition and to enable a continuous supplying of ice pieces having approximate constant ice quality to be performed by a method wherein a bottom surface of ice compressed piece is formed with a tapered part for generating a partial force for bending the ice and pushing it as ice piece. CONSTITUTION:Bottom surfaces of ice compressed pieces 22, 22... are formed with tapered portions 24, 24... inclined upwardly from a deep part of ice block passage toward a part before its opening. This ice generated at an inner surface of a cooling cylinder 1 is cut off by a helical blade 5 of a rotary body 4. The cut ice is compressed by a friction at an inner surface of the cooling cylinder 1, resulting in showing ice quality of slight solidified sherbet- like ice block and the ice block moves upwardly. Ice 23 having an inner force overcoming an initial spring force moves upwardly and is gradually solidified. As a coil spring 17 is compressed, the ice ascends and the ice compressed piece 22 moves to a certain position, a reaction force caused by compression of a coil spring exceeds a certain predetermined resilient force, resulting in that an outward-directed component force F acting against the ice block 23 is increased by the tapered part 24 arranged at the bottom surface of ice compressed piece, it is broken by that force F to form chip-ice pieces 23 and then the ices pieces are thrown outwardly.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention relates to an ice chip supply device for compressing ice produced in an auger ice maker and for dividing and discharging ice as wood chips.

(b) Conventional technology Auger-type ice makers, as exemplified in Jikkosho (il-289! Push the ice block into the passage of the compression head provided at the top opening of the cylinder,
Generally, the structure is such that a cutter that closes the outlet end of the ice block passage compresses the ice, and a rotating cutter cuts the ice into pieces and releases them. Due to differences in ice-making conditions (lower outside temperature, lower water temperature), a large amount of ice is produced.
In order to prevent the locking of the motor for rotating the spiral blade due to the blockage of the ice block in the over-compressed state, the increased load on the ice making cylinder, and the formation of crumbled ice due to uncompressed ice, we devised a way to allow the cutter to escape. The problem has been resolved. Furthermore, as another measure to solve the above-mentioned problems, attempts have been made to make the shape of the ice block passage tapered, and this method is gradually becoming mainstream.

(c) Problems to be Solved by the Invention As described above, the above-mentioned problems have conventionally been solved by improving the structure of the cutter and the shape of the ice block passage, but the present invention uses a method different from these methods. It is an object of the present invention to provide a wood chip supply device for an auger-type ice maker that eliminates the above-mentioned problems, has a relatively simple structure, and can produce wood chips of uniform water quality under any usage conditions.

(d) Means for Solving the Problems In the wood chip supply device for an auger-type ice maker according to the present invention, a rotating body having spiral blades rotates inside a cooling cylinder, scrapes ice from the inner wall of the cylinder, and the scraped ice is directed upward. A plurality of ice block passages are formed around the upper bearing that supports the rotating body, and each ice block passage is constantly filled with an elastic force so as to press down on the upper part of the ice block pushing up. An ice compression piece is provided that can move vertically to compress the ice, and the bottom of each ice compression piece has a set elasticity that allows the pressure of the ice block pushing up in this passage to be applied to the ice. When the force is exceeded, a tapered part is formed that acts on the ice block, causing it to break into pieces of wood and be ejected to the side.

(e) Operation The ice that is pushed up in the ice block passage is pressed down by the ice flake compression pieces and begins to be compressed. Furthermore, as the compression progresses and a force that exceeds the set elastic force of the ice compressed pieces acts on the ice block, a strong outward force is applied by the tapered portion of the lower surface of the ice compressed piece, causing the ice block to break into ice pieces. and is expelled to the outside. As the spiral blade rotates, this phenomenon occurs on the ice in the adjacent ice block passage one after another, and wood chips are continuously ejected.

(f) Example An embodiment of the present invention will be described below based on the drawings.

Reference numeral 1 denotes a cooling cylinder having an outer peripheral surface wrapped with evaporator W2 of a refrigeration cycle and further covered with a foamed heat insulating material 3, the upper part of which extends from the heat insulating part and has an open top surface. Reference numeral 4 denotes a rotating body provided in the cooling cylinder 1, which has a spiral blade 5, and as it rotates, the spiral blade 5 scrapes off the ice layer generated on the inner wall of the cooling cylinder 1, and moves the scraped ice upward. Push it away. Reference numeral 6 denotes an upper bearing which pivotally supports the upper part of the rotating shaft 7 of the rotating body 4, and is fixed to the cooling cylinder 1 by a bolt 8 inserted from outside the outer wall 1' of the cooling cylinder 1, with its upper half protruding. It is attached and fixed to the upper opening of the cooling cylinder l. Reference numeral 9 indicates an insertion hole for the bolt 8, and reference numeral 10 indicates a mounting screw portion thereof. A plurality of ice block passages 11.11... are formed around the upper bearing 6, and these ice block passages 11.11... The ice piece compression passages 12, 12... are formed with the ice piece compression pieces. Reference numeral 13 denotes a head member that is attached and fixed to the L end surface of the upper bearing 6 with three fixing screws 14, 14, and 14 inserted from above, and the fixing screws 14 are inserted into insertion holes formed in the head member 13. 15 and formed in the upper end surface of the upper bearing 6

The head member 13 includes coil springs 17, 17...
A circular recess 18.18... is recessed from the lower surface for storing the pins 19.19, 18. ... through holes 20, 20... are formed. Pin 19.19...
* has a threaded part 21.21... cut in the lower end of the shaft, and the pin 19.1 inserted through the insertion hole 20.20...
After the coil springs 17, 17, . 22.22
... is fixed with screws. In this way, ice compressed pieces 22.
In the normal state, the pin heads 19, 19... with 22... attached to the lower ends are brought into contact with the head member 13 as shown in FIG. 4, and the coil springs 17, 17... are expanded. In this state, the upper end of the receiver is fixed to the ceiling wall of the recess, and the lower end of the receiver is fixed to the ice compression piece 22, 22, . . . . Therefore, this pin 19.19... is the ice compressed piece 22.22.
When the ice block 23 pushing up the ice block passage receives a push-up blade from below, the coil spring 17.17.
Shrink...

The blade moves upward from the head member 13, and when the force is removed, it is pushed down by the spring force and returns to its original state, and moves down L depending on the degree of the push-up blade. Tapered portions 24, 24, . . . that slope upward from the back of the ice block passage toward the front of the opening side thereof are formed on the bottom surfaces of the ice compressed pieces 22, 22, . Due to the existence of the tapered portions 24, 24..., the compressive force from the coil springs 17, 17, which acts on the ice blocks that push the ice block passages 11, 11..., pushes the ice down. It can be divided into a downward force and a lateral force that tries to push the ice sideways.

Then, the ice gradually pushes down and the coil spring 17
．． When the compressive force received from 17... exceeds the set value and the ice block 23 receives that force, the lateral force F acting on the ice block 23 becomes considerably large, and finally, as shown in Fig. 6, the ice block 23 is broken near the open end of the cooling tube 1 and becomes ice pieces 23' which are emitted outside. In FIG. 2, only one ice compression piece 22, coil spring 17, and pin 19 are shown for convenience of explanation, but in reality, the remaining five identical parts W1 are provided.

Next, the effects of these configurations will be explained using FIGS. 4, 5, and 6.

The thin ice generated on the inner surface of the cooling cylinder 1 is removed by the g!
! The shaved ice is scraped off by the A turning blade 5, and is initially compressed by friction on the inner surface of the cooling cylinder 1, and becomes water with a quality similar to that of lightly hardened sherbet, and moves upward. The ice pushed up pushes into the ice block passages 11, 11... and the upper end of the ice 23 presses against the compressed ice piece 22 as shown in Figure 4, but in order to advance any further, the ice overcomes the coil spring 17. It must have just the inner side. Therefore, this inner part determines the water quality. The ice 23, which has an internal force sufficient to overcome the initial spring force, moves upward, and as the spring force increases, the ice 23 moves further upward while increasing its inward direction as shown in FIG. 5, and the ice becomes hard.

Then, when the coil spring 17 is compressed further and the ice rises and the ice compressor piece 22 moves to a certain position, the reaction force due to the compression of the coil spring exceeds the set elastic force, and as a result, the bottom of the ice compressor piece The outward component force F acting on the ice cube 23 increases due to the tapered part 24 provided in the cooling cylinder 1 as shown in FIG.
It breaks off at the open end and becomes ice chips 23', which are thrown outward. After this, the ice compressing piece 22 immediately descends, presses down the next piece of ice, and repeats the above operation. As the spiral blade 5 rotates, this operation is sequentially performed in the adjacent ice block passages 11, 11..., and the pieces of wood 23
' is continuously supplied and released.

By changing the force of the coil spring 17, it is possible to obtain ice of any hardness.In particular, by making the coil spring very weak, it is possible to obtain ice flakes that harden very poorly.

(G) Effects of the Invention] According to the present invention, the leading edge of the ice rising up the ice block passage is held down by elastic force in each ice block passage formed around the upper bearing of the spiral blade. A tapered part is formed on the bottom surface of the ice compressed piece to generate a force that breaks the ice outward and pushes it out as ice pieces, so that the ice in any ice block passage is It is subjected to a fixed compression state with an almost constant elastic force. After being compressed to a certain level, it is automatically released as ice chips. Therefore, with a simple structure, ice chips of almost constant water quality can be continuously supplied one after another. Moreover, by changing the coil spring or the like that imparts elastic force, it is possible to easily create wood chips with different water quality.
