Description

[Detailed description of the invention] (Field of industrial application) This invention relates to an electric ice shaver that automatically shaves off a certain amount in relation to the roughness of the shaved ice.

(Prior art) Shaved ice made with an ice shaver uses ice blocks such as cube-shaped ice made in a refrigerator, commercially available block ice, etc., and a receiving container is prepared under the outlet provided on the cutting plate. , start a rotating mechanism driven by a motor to scrape off the ice block;
It is configured to receive and serve in a receiving container, and when the required amount is reached, the electric motor is switched off and the rotating mechanism is stopped.

In this case, the operator visually determines whether the required amount of shaved ice has been placed in the receiving container, and the amount of shaved ice placed on the receiving container may vary due to individual differences, resulting in irregularities in the amount of shaved ice placed on the receiving container.

The volume of the serving also differs depending on the coarseness of the shaved ice.

(Problems to be Solved by the Present Invention) The purpose of the present invention is to make it possible to maintain the same amount of cutting and the amount of material placed in the receiving container regardless of individual differences among workers, regardless of whether anyone is doing the work.

(Means for Solving the Problems) The present invention aims to solve the problems mentioned in the previous section. The system controls the operating time of the vehicle and allows the operating time to be variably adjusted. More precisely, a control mechanism is provided in the motor drive circuit, and a timer that can be set in advance for a predetermined time is interposed therebetween to operate the motor for the predetermined time.

(Function) The amount of shaved ice made by an ice shaver varies depending on the type of raw ice, the cutting rotation speed of the ice shaver, the installation state of the cutting blade, etc., but the measurement standards are as follows: It is more common and easier to understand to express it by weight.

Therefore, based on past experience, the standard serving amount of a container is determined by weight, and the cutting time of this amount of shaved ice is set in advance on the timer of the control mechanism.If the motor is driven for the set time, the predetermined amount of shaved ice will always be served. will be done.

In addition, shaved ice with a large roughness has a relatively small volume, and conversely, a shaved ice with a fine roughness has a relatively large volume, and the cutting time is proportional to the volume, and the cutting time for a shaved ice with a large roughness is relatively short. The thinner the material, the longer it takes. By making use of this correlation phenomenon and controlling the drive time of the motor by adjusting the setting time of the timer, the amount of shaved ice to be served will be exactly the predetermined amount even when the roughness differs as mentioned above.
Compared to conventional methods based on visual judgment, this method is automatic and ensures the same amount for each arrangement.

(Example) Fig. 1 shows an example of an ice cutting machine for cutting ice cubes.A drive shaft 2 rotated by a motor M is passed through the center of the bottom of a cutting plate 1 consisting of a conical ice case. A rotating mechanism 3 consisting of several blades that presses the cube ice blocks against the inner surface by rotation is fixed inside the plate 1, and a hopper 4 is attached to the upper end of each blade, above the upper and lower exterior plates 5 that cover the entire ice shaving mechanism. An opening/closing cover 6 provided in the section can be opened and closed to supply ice cubes to the hopper 4, and a vertical slit-shaped discharge port 7 is provided in the conical cutting plate 1.
A shaved ice discharge guide 8 protruding from the exterior plate 5 is attached to the discharge port 7, and a cutting blade 9 whose protrusion degree can be adjusted is provided outside the discharge port 7 within the cutting case. As shown in FIG. 2, the cutting blade 9 is a bent head of a cutting roughness adjustment plate 13 supported by a shaft 12 on a protruding arm 11 of a base plate 10 attached to the outside of the cutting plate 1 at the side of the discharge port 7. 14, and the cutting roughness adjustment plate 13 is located to the left of the shaft 12 (second
) is made almost parallel to the base plate 10, the adjustment screw 15 fixed to the base plate 10 is loosely inserted, and the spring 1 is inserted between the base plate 10 and the cutting roughness adjustment plate 13.
6, screw the adjustment handle 17 onto the adjustment screw 15 on the outside of the cutting roughness adjustment plate 13, and connect the dial part 18 of the handle to the side of the discharge guide 8 of the exterior plate 5 (see FIG. 1). It consists of a known structure that protrudes freely in rotation (not shown).

The present invention is such a device equipped with a motor control mechanism, and has a timer T with a dial 21 externally exposed on the upper front of the exterior plate 5, and a push button switch 24 as shown in FIG. Set up, dial 2
Displaying the cutting roughness, for example, a symbol 23 such as standard roughness, 1/2 roughness, double roughness, etc. on the exterior plate 5 at the outer periphery of 1,
A reference symbol 22 is provided on the dial 21.

FIG. 4 shows the control circuit for the motor M. Along with the operation of the push button switch 24, the reset type timer T operates for a preset time using its dial 21, and its output circuit operates the SSR to control the motor M. The timer T is driven until it reaches the set time limit. Incidentally, 25 is the main switch of the ice cutting mechanism.

The operation of this embodiment is as shown in FIG.
Rotate the dial part 18 of 7 to adjust the degree of protrusion of the cutting blade 9 to the cutting plate 1, set the cutting roughness to the standard roughness described later, and then turn the dial 21 to the reference symbol 2.
2 to set the operating time of the timer T, and then operate the push button switch 24 to drive the motor M until the time limit set for the timer T is reached.
The shaved ice which is cut and discharged from a discharge guide 8 is received and served in a receiving container, whereby the amount of served ice is always constant and there is no difference in serving due to individual differences.

Each time the degree of protrusion of the cutting blade 9 is adjusted to change the cutting roughness, the setting time of the timer T is adjusted by the dial 21, and the setting time of the timer T is adjusted by the dial 21 in order to keep the amount of filling constant.

That is, to describe the embodiment, the degree of protrusion of the cutting blade 9 differs slightly depending on the model of the ice cutting machine, but as a general example, the standard roughness is about 0.6 to 0.7 mm. The ice shaving capacity also varies depending on the model, but the standard for the model for ice cubes is 1.5Kg/min., and the standard amount of ice in the container is 200g. In this case, the setting time of the timer T is 8 seconds for the standard roughness shown in FIG. 3, 4 seconds for the double roughness, and 16 seconds for the 1/2 roughness.

It goes without saying that the present invention can also be easily applied to an ice shaver for block ice.

(Effects) This invention has a mechanism installed in the drive motor circuit of the ice shaver to control the operating time of the motor, so shaved ice can always be automatically dispensed in a fixed quantity into the container, making it easier for workers to This method not only eliminates the trouble of manually operating and visually determining the amount, and also prevents variations in the amount of serving, it also has the advantage of being able to match the roughness of the cutting to the time of motor drive.
