Description

[Detailed description of the invention] This invention relates to an ice shaver.

As a conventional ice shaving machine, there is a base 1 as shown in Figure 1.
A drive shaft 4 is rotatably mounted between the lower end of the frame 2 and the shaving plate 3 via a ball bearing 5.6, and a rotating hopper 7 in the shape of a truncated cone is attached to the upper end of the drive shaft 4. A truncated cone-shaped casing 8 is mounted and fixed on the L edge, and a large pulley 9 is fixed on the lower end of the drive shaft 4, and is attached to the wall of the frame 2. A belt 12 is wound around a small pulley 11 fixedly attached to a rotating shaft 10a of a motor 10.

In order to cut ice cubes with the ice shaving machine, the ice cubes are supplied to the casing 8, and then the motor 10 is driven to transmit the rotation from the small pulley 11 to the drive shaft 4 via the belt 12 and the large pulley 9. The casing 8 is rotated in a predetermined direction and successively scraped off by a cutting blade (not shown).

However, in this case, the large and small pulleys 9,
11 and the belt 12 are indirectly connected to the casing 8 via the drive shaft 4, the number of parts increases, the structure becomes complicated and large, and the manufacturing cost increases.

Furthermore, the above-mentioned large and small boos IJ 9, 11 and belt 12
etc. are installed below the casing 8, that is, on the base 1 side, so cutting powder or splashes from the cut ice blocks may fall onto the large and small pulleys 9.
, 11, belt 12, etc., which is undesirable because it becomes a cause of slippage, rust, etc.

In addition, since the conventional ice shaving machine described above has a rotating hopper 7 in the shape of a truncated cone on the top surface of the casing 8, the number of parts increases, the labor required for manufacturing and assembly increases, and the manufacturing cost is high. The tube had various drawbacks.

This invention is an improvement on the conventional ice shaving machine in view of the above-mentioned drawbacks, and the structure of this invention will be explained below based on an embodiment shown in the drawings.

In Figures 2 to 5, 13 is the ice shaver body, 14
Reference numeral 16 denotes a frame that is installed upright on the ice shaving machine main body 130 and the base block 15, and 16 is a shaving plate that is fixedly installed above the frame 14 and has a substantially U-shaped cross section. A cutting blade mounting groove (not shown) is bored.

Reference numeral 17 denotes a truncated cone-shaped casing that is rotatably mounted on a shaft 18 that stands upright in the center of the shaving plate 16. A plurality of casings (three in the drawing) are attached to the lower half of the casing at predetermined positions on the inner circumferential wall 17a. ) are formed radially and at equal intervals.

That is, the upper half of the casing 17 is made a part of the hopper.

Further, the upper end edge of the rotary blade 19 is configured to be inclined in the direction of rotation of the casing 17, and the lower end edge of the rotary blade 19 is located close to the upper surface of the shaving plate 16.

Furthermore, since the above-mentioned lifting sink 17 is formed into an integral truncated conical shape (-7) as described above, the rotating hopper of the conventional ice shaver can be eliminated and the structure can be simplified. 1 and 20 are dog pulleys installed at predetermined positions on the outer circumferential surface of the casing 17, and 21 is a motor for rotating the casing 17, with its rotating shaft 21a being above the motor body and a shaft erected on the shaving plate 16. 18
Place the shaving plate 16 parallel to the
The motor mounting board 22 is installed on the side wall of a motor mounting board 22 that is erected in parallel with the frame 14 at the rear lower part of the motor mounting board 22 .

A small pulley 23 is installed on the rotating shaft 21a of the motor 21 so as to face the large pulley 20, and a belt 24 is wrapped around the small pulley 23.

25 is a guide tube for discharging shaved ice provided at a position facing the cutting blade mounting groove provided on the shaving plate 16;
26 is a lower base block 15 facing the guide tube 25.
A container is placed on this tray with a saucer placed on top.

Reference numeral 27 denotes a blade cover having a fitting hole 27a attached to the open L edge of the shaving plate 16, and 28 stands at the upper outer peripheral edge of the blade cover 27 and between the large pulley 20 and the small pulley 23. The waterproof plate 29 is a head cover installed on the shaving play 1/16, 30 is a cap provided on the head cover 29 so as to be openable and closable, and 31 is a drive switch provided on the upper surface of the head cover 29 directly above the motor 21.

32 represents a front cover, and 33 represents a motor cover.

In the above configuration, the cap 30 is opened, ice cubes are supplied from the upper end of the opening of the casing 17 to the upper end of the opening, and the drive switch 31 is turned on to drive the motor 21, and its rotation is transferred from the small pulley 23 to the belt 24, The signal is transmitted to the casing 17 via the large pulley 20, and the casing 17 is rotated in a predetermined direction.

At this time, the casing 17 rotates the ice block supplied therein by generating centrifugal force by the rotary blades 19, and also rotates the ice block along its inner surface due to the inclination angle of the inner circumferential wall 17a of the casing 17. The guide tube 2 is lowered and cut by the cutting blade installed below.
5 to a suitable container placed on a saucer 26.

As explained above, the present invention has a casing equipped with a dog pulley at a predetermined position on the outer circumferential surface of the casing, which is rotatably mounted on the shaving play 1 and the shirt I installed upright, so that the rotation shaft of the motor is located above the motor body. A motor is installed at the bottom of the main body below the shaving plate so as to be parallel to the shaft, and a small boob iJ is mounted on the rotating shaft of the motor, facing the dog pulley. A belt is wrapped around the dog pulley and the small pulley, a waterproof plate is provided between the dog pulley and the small pulley, and a drive switch is provided directly above the motor.
The single can be directly rotated by the motor via large and small pulleys and belts, eliminating the need for other intermediate members for power transmission and power transmission direction conversion, improving power transmission efficiency and significantly reducing the number of parts. The structure is simple,
As a result, the space above the motor becomes larger, so a switch can be provided using this space, and an ice shaver that is easy to manufacture, inexpensive, and compact can be provided.

In addition, in order to rotate the casing at high speed, the small pulley must be made relatively large in diameter so that the reduction ratio between the dog pulley and the small pulley is small, but there is a large space above the motor, so the small diameter pulley can be made to any size. can.

Furthermore, since large and small pulleys and belts are provided on the upper part of the casing, it is possible to relatively reduce the adhesion of splashes, etc., to the large and small pulleys and belts, etc. in the area of cutting powder from ice blocks, thereby reducing the occurrence of slips, rust, etc. In addition, even if the belt is contaminated with droplets, the drive mechanism can be adjusted to any size by installing it on the top of the casing, increasing the contact area between the belt and large and small pulleys, and reducing the coefficient of friction. By increasing the size, it is possible to eliminate the occurrence of slips and the like.

Furthermore, the existence of a waterproof plate installed between the large and small pulleys can block water droplets from scattering from the casing.
In addition to improving the rust prevention effect of small pulleys, motor rotation shafts, and drive switch contacts, the heavy motor can be installed at the bottom of the main unit by pressing the machine with the hand that operates them. One of the things that can be achieved is that it works stably and well.
