Description

[Detailed description of the invention] This invention relates to a flour mill for sprinkling, which can automatically grind dry foods such as dried sardines and seaweed for sprinkling, and is mainly suitable for home use.

Conventionally, when using the above-mentioned sprinkling crusher, the upper opening of the crushing chamber is closed by a lid, so that a safety switch is turned on, and the ON operation of the power switch becomes effective. The lid and the opening end of the crushing chamber are provided with a dispensing opening that is aligned with each other by rotating the lid. The above safety switch is designed to turn OFF only when the lid is removed. Therefore, if you turn on the power switch with the dispensing spout open, for example, after grinding and cooking, turn the lid to remove the rice. If you accidentally turn on the power switch when you are trying to sprinkle powder on something like the above, the powder in the grinding chamber will fly out of the spout due to the rotating action of the grinding blade and stain the surroundings, such as the desk top.

This idea solves the above drawbacks by blocking the upper opening of the grinding chamber with the lid but not allowing electricity to be applied even if the power switch is turned on unless the outlet is closed, i.e. by preventing the grinding blades from rotating. The purpose is to eliminate the problem.

An embodiment of this invention will be described below based on the drawings. In Fig. 1, 10 is the lower case 11
This is a main case consisting of an upper case 12 and an upper case 12. A motor 14 is supported on the lower surface of the upper wall portion 13 of the lower case 11. A rotating shaft 15 of the motor 14 projects above the upper wall portion 13, and a drive shaft 16 is fixed to the projecting portion. 17 is a power source stored below the motor 14, such as a dry battery; 18 is a lead piece connected to one pole 19 of the power source 17;
A power switch 22 is constituted by the tip end 20 of this lead piece 18 and one external terminal 21 of the motor 14. An operating knob 24 protruding from the side wall of the lower case 11 is provided on the tip 20 side of the lead piece 18 .

The inside of the upper case 12 is configured as a crushing chamber 25, and a lid 26 is detachably attached to the outer peripheral portion 46 of the upper opening of the crushing chamber 25. As shown in FIG. 2, a spout 27 and a recess 28 are formed on the side of the lid 26, and a spout 29 corresponding to the spout 27 is formed at the open end of the grinding chamber 25. In this case, the outer peripheral portion 46 is made circular, and the lid 2 that is attached to the outer peripheral portion 46 is circular.
6 also have the same circular shape, the openings 27 and 29 can be brought into alignment by rotating the lid 26 while maintaining the attached state.

The outer circumferential portion 46 is made into a polygonal shape, and the lid body 26 is also made into a polygonal shape as shown in FIG.
6 is removed once, the direction is changed and it is attached again, and the swinging port 29
can also be made to match, and in this way, the lid body 26 will not be inadvertently rotated during crushing or shaking out.

30 is a blade holder in which a crushing blade 31 is provided in a wing shape. The blade holder 30 has a cylindrical portion 3 that protrudes downward.
2 is rotatably provided in the center of the bottom wall 33 of the crushing chamber 25, and is fitted onto the drive shaft 16 so as to be integrally rotatable.

Reference numeral 34 denotes an operating rod which is provided on the main body case 10 so as to be movable up and down, and at least its lower end portion is made of a conductive material. A collar 35 is provided at the bottom of the operating rod 34, and this collar 35 is elastically supported by a spring member 36. The upper end 37 of the operating rod 34 is allowed to move upward when the two swinging openings 27 and 29 are aligned, that is, it protrudes from the lid support step 47 of the upper case 12 and reaches the recess 28 of the lid 26. It is said that it can be inserted into. Lower end 38 of operating rod 34
A normally open contact type safety switch 44 is constituted by a tip 41 of a lead piece 40 connected to the other pole 39 of the power source 17 and a contact piece 43 connected to the other external terminal 42 of the motor 14. There is.

In the above configuration, after the sprinkling material is put into the crushing chamber 25, the lid 26 is attached. At this time, as shown in FIG. 4, if the outlet ports 27 and 29 are not aligned with each other, that is, in the closed state, the upper end 37 of the operating rod 34 is
is pushed down against the spring force of the spring member 36,
The lower end 38 of the operating rod 34 is pushed between the tip 41 of the lead piece 40 and the contact piece 43. That is, the safety switch 44 is turned on. Motor 1
4. Since the power supply 17, power switch 22, and safety switch 44 constitute a series circuit, when the safety switch 44 is in the ON state, the operation knob 24
When the power switch 22 is turned on, the circuit becomes a closed circuit, the power source 17 is connected to the motor 14, the blade holder 30 rotates, and the crushing blade 31 starts milling. In this state, both the shaking out ports 27 and 29 are in a closed state, so that the powder in the grinding chamber 25 does not fly out to the outside.

On the other hand, even if the lid body 26 is attached, if both the swing out openings 27 and 29 are aligned and in the open state as shown in FIG. Then, it is fitted into the recess 28 by the spring force of the spring member 36. At this time, the end wall of the recess 28 in the rotation direction is inclined, and the upper end 3 of the operating rod 34
Since the head part 7 is rounded, the operating rod 34 can be smoothly moved up and down simply by rotating the lid body 26. As a result, the lower end 3 of the operating rod 34
8 is removed from between the tip 41 of the lead piece 40 and the contact piece 43, and the safety switch 44 is turned off. Therefore, in this case, even if the circuit becomes open and the power switch 22 is turned on, the motor 14 is not energized, and the crushing blade body 31 rotates and the crushing chamber 25 is turned on.
The powder inside will not fly out from the outlet 27, 29.

When the lid 26 is removed after milling, the operating rod 34 is moved upward by the elastic force of the spring member 36. That is, the safety switch 44 is turned off.

As described above, according to this invention, even if the upper opening of the crushing chamber is closed with the lid, the crushing blade will not be able to rotate unless the outlet is closed.
It is possible to provide a sprinkling flour mill that can prevent powder in a grinding chamber from flying out from a spout during grinding.
