Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a combined ice cutting and ice crushing machine, which is capable of both cutting and crushing ice cubes.

(Prior art) As shown in Japanese Patent Application Laid-Open No. 56-68773, a cutting blade is provided that always protrudes into the case from the outlet of the cutting case, and an ice-breaking blade is placed at the front side of the cutting blade in the direction of movement of ice cubes inside the case. The cutting edge is lower than that of the cutting blade and is fixed below the case surface, the front cover of both blades is rotated to hang down, the outlet is opened to crush ice, and the cover is held horizontally and the case surface and Since the ice is shaved using a small discharge outlet on the same plane, the ice-shaving blade acts even during ice-breaking, and a small amount of shaved ice gets mixed in.The blade also wears out quickly and there are many chances for the blade to spill. There is.

(Problems to be Solved by the Invention) In view of the above, the present invention allows the cutting blade and the ice-breaking blade to be alternately moved in and out of the ice case through an outlet of one ice case, and to control the ingress and egress of the ice case by a single switch. This is done by changing the direction of rotation of the rod, and the purpose is to make it possible to adjust the degree of protrusion of the cutting blade and the ice-breaking blade into the cutting case to a certain extent by using the switching rod.

(Means for Solving the Problems) The present invention has been made to meet the object stated in the previous section, and the small ice cubes supplied in the cutting case are rotated by a rotating body in the case and cut by a cutting blade. In the device for discharging cut snowflakes from the discharge port of the case, the cutting blade and the ice-breaking blade are slidably overlapped and fit into guide grooves provided in a holder base provided on the outside of the cutting case, and A first feed screw and a second feed screw formed with opposite thread directions on one switching rod rotatably supported by a base are respectively engaged with screw holes provided in the double-edged tool, By rotating the switching rod in a different direction, the cutting blade and the ice-breaking blade are alternately and selectively projected from the discharge port into the cutting case.

Preferred embodiments of the present invention will be described with reference to the accompanying drawings.

7 will be provided. A shaft pin 37 is inserted into the shaft hole 17 on the front surface of the base plate 15 as shown in FIG. A square rod-shaped support plate 20 is provided at a side position, and a hole 21 for insertion of a switching rod is formed in the latter. The base plate 16 has a guide groove 22 for ice-breaking blades.
The blade guide 19 is provided with a guide groove 23 for the cutting blade.

Reference numeral 24 denotes a cutting blade which is slidably passed through the guide groove 23 of the cutting blade, and is provided with a cutting blade block 25 projecting at right angles at the rear end thereof, which is aligned with the axis of the insertion hole 21. A screw hole 26 is provided (FIG. 4).

Reference numeral 27 denotes an ice-breaking blade which is slidably superimposed on the back of the cutting blade 24 and slidably passes through the guide grooves 22 and 23, and has a comb-shaped ice-breaking blade 28 at its tip. A mounting plate 29 that fits into the guide groove 22 is attached to this ice-breaking knife 27, and an ice-breaking block 30 that projects at right angles is provided at the rear end of the mounting plate 29, and the ice-breaking block 30 is aligned with the axis of the insertion hole 21. Spiral hole 3
1 (Figures 5-8).

Reference numeral 32 denotes a switching rod, which has a reduced diameter portion 33 provided at the center in the longitudinal direction, which is freely rotated through the insertion hole 21, and fixed in position by a screw 36.
For example, there is a rightward first
A feed screw 34 is provided, a second feed screw 35 is provided in the left direction behind the reduced diameter portion 33, and a first feed screw 34 is provided.
is screwed into the screw hole 26 provided in the cutting blade block 25 of the cutting blade 24, and the second feed screw 35 is inserted into the ice-breaking blade 27.
It is screwed into the screw hole 31 provided in the ice crushing block 30.

The cutting blade 24, the ice-breaking blade 27, and the switching rod 32 are combined into a block shape on the base plate 16.
The holder base 15 is attached to the support piece 10 by the shaft pin 37.
Attach to. At this time, the protrusion adjustment lever 18 is made to correspond to the cam 38 rotatably provided on the second arm 13, and between the lever 18 and the support piece 10,
Spring 39 for pressing the lever 18 against the cam 38
(Figures 7 and 8).

(Function) For example, when the switching rod 32 is rotated clockwise, the cutting blade 24
is projected into the case from the outlet 8 of the cutting case 3 by the first screw 34, and at the same time, the ice-breaking blade 27 is retracted to the outside of the outlet 8 by the second screw 35 (FIG. 7). When the switching rod 32 is rotated counterclockwise, the cutting blade 24 is retracted from the outlet 8 to the outside of the case, and the ice-breaking blade 27 is instead protruded into the case 1 from the outlet 8 (FIG. 8). Also, the cutting blade 24 in FIG.

(Effects) The present invention provides a holder base 15 that corresponds to the discharge port 8 on the outside of the cutting case 3 and has a knife guide groove 22 directed toward the discharge port 8, so that the cutting knife 24 and the ice-breaking knife 27 can be slid together. The cutting blade 24 and the ice-breaking blade 27 are provided with female threads 26 and 31, respectively, which are placed in a line with each other in the sliding direction of the blades, so that the cutting blade 24 and the ice-breaking blade 27 are stacked and pressed against the base 15 so as to be freely movable. The switching rod 32 is provided with a switching rod 32 formed with a first screw 34 and a second screw 35 with opposite thread directions, and the female screw 26 and the first screw 34 and the female screw 31 and the second screw 35 are screwed separately. By rotating the switching rod 32 in a different direction, either the cutting blade 24 or the ice crushing blade 27 is moved to the discharge port 8 by the action of the first screw 34 and the second screw 35.
One protrudes into the cutting case 3 from one side and at the same time withdraws the other side from the outlet 8 to the outside of the cutting case 3.
The knife that has retreated to the outside from the discharge port 8 has no relation to the ice inside the case 3. In addition, the above-mentioned blade can be changed easily by rotating the single switching rod 32, and the cutting blade 24 and the ice-breaking blade 27 are strongly supported by a single holder base 15, which increases durability. It has the effect of improving the
