Description

[Detailed description of the invention] This invention is an ice crusher in which falling ice piece roughness limiting members are arranged on the forward and reverse rotation sides of a crushing cutter that rotates in both forward and reverse directions to catch ice blocks larger than a predetermined size and crush them by the crushing cutter. Regarding.

This type of ice crusher was first proposed by the applicant, and the crushing cutter and falling ice flake roughness limiting member are designed to meet the crushing conditions between opposing parts on the normal rotation side and between the opposing parts on the reverse rotation side. By simply selecting the direction of operation of the crushing vine, whether the crushing vine is rotated in the forward direction or in the reverse direction, the crushing conditions at
Two types of crushed ice are freely available.

However, since there are only two types of roughness adjustment, it is still not satisfactory for obtaining crushed ice with a roughness suitable for drinking, cooking, or tastes.

In order to achieve the above-mentioned purpose, this invention has two parts on the forward and reverse rotation sides of the forward and reverse rotation crushing vine.
In an ice crusher equipped with a falling ice piece roughness limiting member that receives ice blocks and crushes them with a crusher cutter, the base of the roughness adjusting member is rotatably attached to the rotating shaft of the crusher cutter, and the roughness adjustment member is attached to the peripheral wall of the ice block input hopper. The present invention is characterized in that positioning portions are provided for positioning the member on the forward and reverse sides.

First, the embodiment shown in FIGS. 1 to 3 will be described. A hopper 2 into which ice cubes are placed is fitted into the upper part of a main body 1 formed into a cylindrical shape. The hopper 2 is screwed 4 to the inner sole 3 of the main body 1, and has an outlet portion 5b facing downward and communicating with a drop opening 5a formed in the inner sole 3. This outlet portion 5b is provided with a falling ice piece roughness limiting member 7 that partitions the outlet portion 5b into ice piece falling gaps 6 of appropriate widths, and a forward and reverse rotating crushing cutter 8 that passes through each ice piece falling gap 6. ing.

The crushing cutter 8 attaches the shaft 9 at different rotational positions to a non-circular cross section 9a in which a part of the rotating shaft 9 installed horizontally at the outlet portion 5b is cut off.
It is fitted so as to rotate together with the shaft 9, and is fixed at a predetermined position on the shaft 9 at regular intervals by a pair of snap rings 10 and a plurality of spacers 11. The shaft 9 is connected to the hopper 2 and the midsole 3.
A passive gear 14 is supported by a pair of bushes 12 held between them, and is fitted into the end of the non-circular cross-sectional portion 9a and prevented from coming off by a snap spring 13.
A drive gear 1 on a drive shaft 17 is directly connected to an external operating handle 15 and is supported by a pair of bushes 16 sandwiched between the hopper 2 and the inner sole 3.
8 to the passive gear 14, the handle 1
According to the direction of operation shown in Fig. 5, either the normal rotation is made in the direction a or the reverse rotation is made in the direction b shown in Fig. 2.

The falling ice piece roughness limiting member 7 has a center portion that is connected to the adjacent spacer 1 located between the crushing vines 8.
The crush cutter 8 and the passive gear 1 are fitted into an annular groove 19 formed on the outer periphery between the ends of 1 and 11.
4 and can be handled as one combination. The end of each falling ice piece roughness limiting member 7 is
It is clamped between two split recesses 20 formed between the outlet portion 5b and the drop opening 5a of the hopper 2 and the midsole 3, and is firmly held without causing chatter.

The falling ice piece roughness limiting member 7 and the crushing cutter 8 have two crushing teeth 7a and 8a, respectively, in the portions that face each other on the normal rotation side and crush ice blocks.
Also, on the reverse side, in the part that crushes ice blocks facing each other,
Three crush teeth 7b, 8b are formed respectively, and the teeth 7a, 8b are formed on the forward rotation side and the reverse rotation side.
The crushing conditions differ depending on the number of teeth 8a and teeth 7b, 8b.
It is possible to crush coarsely between teeth 8a, and finely crush between teeth 7b and 8b, which have more teeth on the reverse side, and which of these teeth to crush is determined by selecting the direction in which the handle 15 is operated.

Below the drop opening 5b, an ice receiver 22, which is taken in and taken out from an inlet/outlet 21 on the front surface of the main body 1, is arranged so as to be received on the bottom plate 23 of the main body 1. 24 is a lid of the hopper 2, which is removably fitted.

The outlet portion 5b further includes a roughness whose attitude is changed to be alternatively parallel to one of the normal rotation side portion 7 ₁ and the reverse rotation side portion 7 ₂ of each falling ice piece roughness limiting member 7. An adjustment member 25 is provided. The roughness adjusting member 25 is provided adjacent to each crushing cutter 8, and the base portion 25c is connected to a stepped portion 2 formed on the outer periphery of the end of the spacer 11 adjacent to the crushing cutter 8.
6, and by rotating around the shaft 9, it is possible to select between a reverse rotation side position shown by a solid line in the figure and a forward rotation side position shown by a phantom line in FIG. I am trying to change my posture. In each of these positions, the roughness adjusting member 25 has its free end 25d at the outlet portion 5.
b It is positioned by being received by an upward step 27 in the middle.

Each roughness adjusting member 25 has a free end 25d.
The two operating pieces 28 are connected with pins 29, so that the operating pieces 28 can change the posture without the risk of touching the crushing cutter 8 or the teeth 8a, 8b, or 7a, 7b of the falling ice flake roughness limiting member 7. The operation piece 28 has a perforated operation part 28a at its free end, and is elastically fitted into a trapezoidal dovetail groove 30 carved in the front wall of the forward rotation side and the reverse rotation side of the outlet part 5b. The free end 25d of the roughness adjusting member 25 is pressed onto the stepped portion 27 because the groove 30 is trapezoidal and prevents upward movement of the operating piece 28. , the member 25 is fixed at each attitude change position,
Chattering caused by impact during crushing work is also prevented.

The roughness adjustment member 25 further divides the ice piece falling gap 6 into half width, regardless of the forward rotation side or the reverse rotation side, and reduces the size of the ice pieces that fall due to crushing to about 1/2.
Therefore, depending on whether or not the roughness adjustment member 25 is used for crushing on the forward rotation side and reverse rotation side, two types of crushing can be performed each, and it is possible to perform two types of crushing on the forward rotation side and reverse rotation side. As a result, crushed ice pieces with four types of roughness are obtained.

The illustrated roughness adjustment member 25 has two crushing teeth 25a on the normal rotation side facing the crushing cutter 8 on the normal rotation side, and three crushing teeth 25a on the reverse side portion facing the crushing cutter 8 on the reverse rotation side.
5b are respectively formed, and when the roughness adjusting member 25 is involved in crushing as a roughness adjusting member on the forward rotation side or the reverse rotation side, the roughness is averaged together with the crushing cutter 8 and the falling ice piece roughness limiting member 7. It acts so that crushing is done efficiently.

In addition to the above, for example, as shown in FIG. 4, holding the operating piece 28 in the forward rotation side and reverse rotation side positions and preventing the upward movement is performed by moving the shoulder portion 28b of the operating piece 28 downward toward the inner surface of the hopper outlet portion 5b. It may be configured to engage elastically with the engagement step portion 31, and in this case, upward movement of the operating piece 28 is more reliably prevented.

5 and 6 show an example in which the roughness adjusting member 25 is arranged adjacent to the falling ice flake roughness limiting member 7, and the roughness adjusting member 25 is placed on the normal rotation side or the reverse rotation side where it is positioned. Then, the ice piece falling gap 6 partitioned by the falling ice piece roughness limiting member 7 is controlled by the roughness adjusting member 25.
The coarseness of the crushed ice pieces thus obtained is made slightly finer. Further, the roughness adjusting member 25 includes crush teeth 25 similar to those described above.
It has a, 25b.

The free end 25d of the roughness adjusting member 25 is only received by the step 27 of the hopper 2, but since the roughness adjusting member 25 is pressed against the step 27 during ice crushing, there is no particular problem. The operating piece for changing the posture is not connected either, but it can be moved directly by hand or by drilling a hole 32 in the free end and engaging the bent end of the operating rod. The structure is often much simpler. Further, the roughness adjusting member 25 has its base 25c fitted to the spacer 11 to the extent that it receives a light frictional transmission, and if the spacer 11 is made to rotate together with the rotating shaft 9, the rotating shaft 9 can be rotated. The roughness adjusting member 25 is rotated in this direction and comes into contact with the stepped portion 27 and stops. By this,
By turning the shaft 9 at least half a turn in the desired direction before throwing ice cubes into the hopper 2, the roughness adjusting member 25 can be changed to a desired position between the normal rotation side and the reverse rotation side, thereby improving the structure. is simple and convenient to handle. From the spacer 11 to the roughness adjustment member 2
As the light friction transmission structure for the transmission mechanism 5, various conventionally known structures may be selected and adopted.

The roughness adjustment member 25 has crush teeth 25a, 2
The roughness can be adjusted by changing the conditions for crushing ice blocks and the number and presence of 5b, and the same goes for the falling ice piece roughness limiting member 7, and various combinations can be used to adjust the roughness. Conceivable. FIGS. 7 to 10 show other examples of such combinations.

According to this invention, in an ice crusher in which falling ice flake roughness limiting members are disposed on the forward and reverse sides of a crushing vine that rotates in both forward and reverse rotation directions, falling ice flakes roughness limiting members are arranged to catch ice blocks and crush them by the crushing vine, and the crushing vine has a rotating shaft for adjusting the roughness. Attach the base of the member so that it can rotate, and attach it to the peripheral wall of the ice block charging hopper.
Since each positioning part for positioning the roughness adjustment member on the forward and reverse sides is provided, a simple structure of just providing the roughness adjustment member can correct the crushing vines caused by the falling ice flake roughness limiting members and the crushing vines on the forward and reverse sides. In addition to the two-step roughness adjustment of rotating or reversing, it is possible to perform a further two-step roughness adjustment depending on whether or not a roughness adjusting member is used at each time of crushing on the forward and reverse sides. Moreover, the roughness adjustment operation can be easily performed.

In addition, the degree of roughness adjustment of the roughness adjustment members can be set in various ways by selecting the number and position of the roughness adjustment members, or the presence or absence of crush teeth, number, shape, etc.
