Description

[Detailed description of the invention] The present invention relates to an ice crusher that crushes small ice blocks such as ice cubes of approximately 3 cm, which are produced by a small ice maker, by adjusting the size of the crushed ice as necessary. A rotating body in which crushing blades are arranged and fixed in the axial direction at required intervals in an ice crushing case, and a comb-shaped blade receiver provided with a cut groove through which the crushing blades pass by rotation are disposed oppositely. A shaft protrudes from both sides of the blade receiver and is rotatably supported on the side wall of the case, and an operating arm is pinned to one side of the shaft so as to protrude forward along the side wall, and is attached to the front part of the side wall. A locking plate having a vertical groove on the operating arm and several stages of engagement teeth that engage the groove is attached, and a spring is provided between the operating arm and the side wall that forces the operating arm to fit into the engagement teeth. The ice crushing device is characterized in that the size of the crushed ice can be varied by providing a safety retaining member, moving the operating arm up and down to engage the engaging teeth, and adjusting the rotation angle of the blade receiver. It is a thing,
The above objective is achieved by easily adjusting the rotation angle of the comb-shaped blade receiver disposed opposite to the crushing blade using an operating arm outside the ice crushing case.

Some small ice crushers for restaurants are equipped with a device to appropriately adjust the size of crushed ice, but it is necessary to adjust the relative spacing between the crushing blade and the blade receiver, which places an extremely large load on it. It is not easy to create a structure that allows this and maintains the strength to withstand the load.

As explained in the examples below, the present invention enables the blade holder to be fixed at a desired rotation angle by the lever action of the operating arm connected to the shaft of the blade holder, thereby improving strength and durability. This is an attempt to increase the number of people.

An embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a square cylinder-shaped ice crushing case with both the top and bottom open,
The upper opening serves as an inlet 2 for small ice cubes and is provided with an opening/closing lid 6.

The lower opening serves as an outlet 3 for crushed ice, and the legs 5 allow a receiver to be inserted into the lower part of the outlet 3.

Inside the ice-breaking case 1, guide plates 7 and 8 for small ice cubes are fixed to the upper front and rear sides in a substantially intrusive manner to provide a falling hole 9, and a part of the guide plate 7 is provided below the falling hole. A rotary drum 10 rotating within the ice crushing case 1 is disposed, and central shafts 11 on both sides thereof are pivotally supported by side walls 4 on both sides of the ice crushing case 1, and a round handle 12 is fixed to the central shaft protruding from one wall surface.

A large number of conical crushing blades 13 are fixed to the outer periphery of the rotary drum 10 at regular intervals in the axial direction and arranged in a spiral shape in the circumferential direction so as to be inclined in the rotational direction.

Furthermore, a comb-shaped blade holder 14 is disposed at the bottom of the guide plate 8, and is provided with a cut groove 15 through which the above-mentioned crushing blade 13 passes.

The blade receiver 14 has a boat-shaped upper surface, and has a shaft 16 protruding from the middle part of both sides in the front-rear direction, supported by the side wall 4, and protruding on the opposite side of the round handle 12. As clearly seen in FIG. 2, a pin 17 is inserted into the shaft 16 in the diametrical direction and protrudes, and the pin 17 has a two-pronged portion 19 at the rear end of a nine-rod-shaped operating arm 18 with a grip 20 attached to the tip. through the grip 2 with its operating arm 18 along the outside of the side wall 4.
Connect so that 0 is at the front.

A cover 21 that loosely covers the operating arm 18 is attached to the outer surface of the side wall 4, and a vertical groove 23 through which the operating arm 18 is vertically movable is cut into the tip opening of the cover 21 from the outer groove edge of the groove. Several stages of engagement teeth 24a, 24b, 24
A locking plate 22 (Fig. 3) provided with C is attached, and two upper and lower headed guide rods 25 are installed slightly behind the locking plate 22.
is fixed to the side wall 4, and a push rod 26 is wound around the guide rod,
The upper and lower ends of the plate-shaped engagement member 27 pushed by the spring 26 are fitted loosely, and the operating arm 18 is brought into contact with the engagement member 27, and the engagement tooth 24 of the arm 18 is pushed by the elasticity of the spring 26. Forcibly engage any one of a to 24C.

The above-described retaining member 27 may be fixed to the operating arm 18 side so as to correspond to the outside of the side wall 4.

In that case, a leaf spring or the like may be fixed to the operating arm 18 as the spring-like engagement member 27.

In the embodiment described above, the grip 20 of the operating arm 18 is grasped, the engaging member 27 is swung to the right in FIG. After the blade escapes into the vertical groove 23, the grip 20 is moved in the vertical direction to fit into any of the engaging teeth 24a to 24C, and the blade holder 14 is moved to any one of the engaging teeth 24a to 24c as shown in FIG. After rotating to the angle shown by the dotted line or the two-dot chain line, the engagement teeth 24 a to 2 are again moved by the elasticity of the spring 26 and the locking member 27.
4C, and adjust the distance between the tip of the blade receiver 14 and the rotating barrel 10.

As clarified by the above description, the present invention has an operating arm 18 connected to the shaft 16 of the blade receiver 14 corresponding to the rotary barrel 10, which protrudes along the outside of one side wall of the ice crushing case 1. A retaining member 2 having a spring property for the arm 18
While pressing outward at 7, the blade holder 14 is fitted and locked into a large number of retaining teeth located far away from the axis of the shaft 16, for example, any one of 242 to 24C, thereby preventing the rotation of the blade holder 14. Since the blade receiver 14 is adjusted and strongly held at that angle, even if an impactful load of ice crushing is applied to the blade receiver 14, the engaging teeth 24a~ The pressure of the load applied to 24 C is reduced in inverse proportion to the length of the operating arm up to the part that engages with the retaining teeth, reducing the pressure burden on the retaining teeth and increasing the overall strength of the ice crusher. The durability can be improved, and the switching operation described above can be easily performed by operating the lever of the operating arm 18. Suitable for crushing ice blocks.
