Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ice shaving / crushing machine having two functions of ice shaving and crushing.

[0002]

2. Description of the Related Art An ice shaving and crushing machine is designed to rotate a plurality of cube-shaped ice blocks in a circular case, project a flat ice shaving blade into the case when shaving ice, and sharpen it when crushing ice. The ice-breaking blade is projected into the case. Various types of blade switching means have been proposed for such an ice shaving and crushing machine, but most switching means operate the ice shaving blade and the ice slicing blade with separate operating members, and therefore both blades are used. In order to prevent objects from protruding into the case at the same time, an erroneous operation prevention mechanism between the operation members is indispensable.

[0003]

SUMMARY OF THE INVENTION According to the present invention, an ice cutting blade and an ice breaking blade can be selectively put into and taken out of a case by a single operating member, so that both blades simultaneously project into the case. There is no need for a mechanism to prevent this, and the structure of the combined ice shaving and crushing machine is to be simplified.

[0004]

According to the present invention, a blade support is rotatably disposed in an opening formed in a surface on which ice blocks are forcibly transferred, and the blade support is provided on both sides of the axis of the blade support. A first structure in which an ice cutting blade and an ice breaking blade are disposed, a blade switching knob is attached to the blade supporting body to rotate the blade supporting body, and the ice supporting blade is projected from an opening by a locking means. The rotation position and the second rotation position where the ice cutting blade projects from the opening are selectively locked.

[0005]

When performing ice cutting, the blade support is rotated to the first rotation position by holding the blade switching knob to project the ice cutting blade from the opening, and at this position, the blade support is locked by the locking means. Lock it. When the ice block passes through the opening, it is cut by the ice cutting blade and discharged from the opening. When crushing ice, the knife support is rotated to the second rotation position by holding the knife switching knob to project the ice-crushing knife from the opening, and the knife support is locked by the locking means at this position. As the ice block passes through the opening, it is crushed by the ice-breaking blade and discharged from the opening. From the turning position of the blade switching knob, it is possible to determine at a glance which of the ice cutting blade and the ice breaking blade protrudes from the opening, so there is no fear of erroneous operation.

Are inserted into holes 84 formed in the rotating plate 54. Therefore, when the adjusting knob 70 is rotated, the rotating plate 54 rotates about the shaft portion 38b.

Next, the operation of the combined ice shaving / crushing machine 10 will be described.

When the dual-purpose machine 10 is used, first the cover plate 20 is used.
Open and put a plurality of ice blocks in the inlet 16. Next, the switching knob 52 is operated to select either ice shaving or crushed ice. When ice shaving is selected and the lock pin 64 of the switching knob 52 is inserted into the first lock hole 56 of the rotating plate 54, the ice shaving blade 40 is moved to the position shown in FIG.
As shown in (b), about 1 to 1.
It protrudes by 7 mm. At this time, the ice breaking blade 42 has an opening 36.
It is completely housed in the recess 50 of the trailing edge 36b. Further, when crushed ice is selected and the lock pin 64 of the switching knob 52 is inserted into the second lock hole 58 of the rotating plate 54, the crushed ice knife 42 projects from the opening 36 onto the bottom plate 32 as shown in FIG. 3A. . At this time, the ice cutting blade 40 moves below the opening 36.

In the case of ice shaving, the ice lumps rotated along the bottom plate 32 while being pushed by the blade portions 22c of the rotor 22 are cut by the ice shaving blade 40 and fall downward from the discharge gap S1. At this time, the protrusion amount of the ice cutting blade 40 can be increased or decreased by rotating the adjustment knob 70. That is, when the adjusting knob 70 is rotated clockwise, the adjusting screw 66 and the moving body 72 are moved leftward in FIG. 4, and the rotating plate 54 is rotated clockwise. At this time, since the lock pin 64 of the switching knob 52 is fitted into the first lock hole 56, the switching knob 52 and the blade support 3
8 rotates clockwise together with the rotating plate 54 in FIGS. 3B and 4, and reduces the amount of tip projection of the ice cutting blade 40. On the contrary, when the adjusting knob 70 is rotated in the counterclockwise direction, the adjusting screw 66 and the moving body 72 move to the right in FIG. 4, and the rotating plate 54 and the blade support 38 are moved in the counterclockwise direction together with the switching knob 52. It is rotated to increase the tip protrusion amount of the ice cutting blade 40. When this protrusion amount is about 1.7 mm or more, the impact force of the ice block against the ice cutting blade 40 becomes large and the blade 40
Since the stopper nut 86 may be screwed onto the adjusting screw 66 and the adjusting screw 66 moves to the right in FIG. 4 to some extent, the stopper nut 86 may be damaged.
The end wall 88 of No. 6 is abutted so that it cannot move further. The stopper nut 86 can freely determine the origin position during assembly.

On the other hand, in the case of crushed ice, an ice block that is rotated while being pressed by the blade portion 22c of the rotor 22 hits the crushed ice blade 42 and is crushed, and falls downward from the discharge gap S2. At this time, the ice-breaking blade 42 is largely projected on the bottom plate 32, but since the blade portion 22c of the rotor 22 is formed with the notch 23 through which the ice-breaking blade 42 can pass, the blade portion 22c is formed.
There is no risk of interference with.

Next, it is desirable to replace the ice cutting blade 40 periodically if it is used for a long time, since it will be spilled and deteriorate in sharpness. There is a feature that replacement of the cutting tool 40 is very easy. That is, when the ice cutting blade 40 is replaced, the switching knob 52 is rotated to move the lock pin 64 thereof.
4 and the third lock hole 60. At this rotating position, the ice cutting blade 40 becomes horizontal as shown by the one-dot chain line in FIG. 3B, and if the screw 41 is loosened with a screwdriver inserted from below, the ice cutting blade 40 can be easily removed from the blade support 38. To fall into.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above-described embodiment, the ice cutting blade 40 is provided separately from the blade support 38, but it is also possible to make them one piece. It is also possible to consider the replacement of the ice-breaking blade 42 as a separate piece from the blade support 38. Further, the lock means for locking the turning position of the blade support 38 is a lock pin 64 and lock holes 56, 58, 60.
Not limited to the combination of, various lock mechanisms can be adopted. Further, in the above-described embodiment, the direction of the axis of rotation of the blade support is set to the radial direction of the bottom plate 32, but it does not necessarily have to be this direction and is different from the radial direction depending on the size and type of the combined ice shaving / crushing machine 10. It may be in the direction of.

[0018]

As described above, according to the present invention, since the shaving blade and the crushing blade are arranged on the rotatable blade supporting body, the shaving blade or the crushing ice can be simply operated by rotating the blade supporting body. You can easily, reliably and speedily select any of the blades. Therefore, it is not necessary to dispose a separate operating means for each blade as in the prior art, and a mechanism for preventing erroneous operation between the operating means can be dispensed with, making it possible to structurally simplify an ice shaving / crushing machine. it can. Furthermore, from the rotational position of the blade switching knob attached to the blade support, it is possible to check at a glance which of the ice cutting blade and the ice breaking blade is selected, or whether these blades are rotating to the correct position, No worries about incorrect operation.
