Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric powder sifter for sifting lumps of flour, cocoa, etc., which can be easily used at home.

BACKGROUND ART A conventional electric powder sieve of this type has a structure as shown in FIG. The details will be explained with reference to FIG.

In the figure, 1 is a cylindrical container for storing powder to be sieved, and a motor 2 is connected to the center bottom by a screw 10.
A motor case 3 is formed to house and fix the sieve 4, and a sieve 4 is fixed to the lower part of the motor case 3. A battery 5 and a switch 6 are installed on the outside of the container 1.
The battery 5 and the motor 2 are connected via a switch 6 and lead wires 8 and 9.

Further, an eccentric weight 12 is fixed to the motor shaft 11 of the motor 2. Therefore, when the switch 6 is closed and the motor 2 is rotated, the motor shaft 1
1 and the eccentric weight 12 rotates, causing the motor 2 to vibrate. This vibration caused the sieve 4 to vibrate via the motor case 3, and the powder such as wheat flour collected in the container 1 was sieved.

However, with this configuration, it is impossible to wash the sieve and container by directly immersing them in water because the motor, battery, etc. are fixed inside the container, resulting in the problem of unsanitary conditions.

Problems to be Solved by the Invention The present invention solves the above-mentioned conventional problems.
To provide an electric powder sieve in which a part contaminated by powder, that is, a container and a sieve part, can be separated from a part housing a motor, a battery, etc., and the container and sieve can be washed by soaking them in water. With the goal.

Means for Solving the Problems In order to achieve the above object, the present invention accommodates a motor, a battery, and a switch in the handle, rotatably attaches the sieve to a support in the container, and A roughly U-shaped rib is formed in a portion, an eccentric shaft is fixed to the motor shaft of the motor, and the handle is removably fitted into the container so that the eccentric shaft fits into the gap between the roughly U-shaped ribs. Moreover, the lower end surface of the handle is formed so that it is recessed than the lower end surface of the container in the fitted state, and the eccentric shaft is rotated by the rotation of the motor, and the eccentric shaft is rotated by an amount twice as eccentric as the eccentric shaft. The sieve was made to vibrate as the amplitude.

Function: After the powder has been sieved, the handle containing the motor, battery, switch, etc. can be removed from the container, and the sieve and container can be soaked in water and washed. In addition, the fitting direction of the handle and container should be determined by considering the usage condition.
By arranging the handle in a direction opposite to the sieving direction of the powder, the handle will not come off due to the weight of the powder during use.

Embodiment Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 4.

In the figure, 21 is a cylindrical container for storing the powder to be sieved. Inside the lower end opening of the container 21, ribs 21a extending toward the center and a support portion 23 are formed at the center where the ribs 21a are concentrated, integrally with the container 21. A support shaft 30 that projects downward is fixed to the support portion 23.

A sieve 24 is rotatably mounted on the support shaft 30, and a retaining ring 33 positions the sieve 24 and prevents it from falling off. In addition, a part of the outer periphery of the sieve 24 is
A substantially U-shaped rib 28 is formed that extends in a direction perpendicular to the rotation direction of 4 and has spaced apart walls.

27 is a handle, a switch 26 is attached to the upper part, a battery 25 and a motor 22 are housed and fixed inside, and the battery 2 is connected by a positive lead 29, a switch 26, a negative lead 34, and a common lead 35.
5 and the motor 22 are connected. 38 is a lid of a battery chamber that accommodates the battery 25. motor 22
An eccentric shaft 32 is fixed to the motor shaft 31 of the motor. A pawl 36 formed on a part of the handle 27 was provided so as to protrude from the outside of the container 21 so that the eccentric shaft 32 fit into the gap between the substantially U-shaped ribs 28 formed on a part of the outer periphery of the sieve 24. It is removably fitted into a fitting hole 37 bored in the protrusion, and the handle 27 and container 21 are fitted integrally. A plurality of convex portions 21b are formed at the lower end of the container 21 so that the lower end surface A of the handle 27 is recessed more than the lower end surface A of the container 21 when the handle 27 is fitted.

The substantially U-shaped rib 28 and the eccentric shaft 32 are connected to the sieve 2.
4 with a slight gap in the direction of rotation, and a free gap in the direction perpendicular to this direction of rotation. Therefore, when the switch 26 is closed and power from the battery 25 is supplied to the motor 22, the eccentric shaft 32 rotates integrally with the motor shaft 31 and slides against the inner wall of the U-shaped rib 28, so that the sieve 24
vibrates horizontally with an amplitude twice the eccentricity of the eccentric shaft 32, and sieves the powder in the container 21.

When washing the container 21, as shown in FIG. 1, the lower end surface A of the handle 27 is recessed than the lower end surface A of the container 21. The handle 27 is detached from the container 21 by simply pushing down the handle 27. The container 21 from which the handle 27 has been removed can be washed together with the sieve 24. In addition, several protrusions 21b are formed on the lower end surface of the container 21.
, the powder adhering to the lower end surface of the container 21 will not stick to the table.

If the stopper 39 of the handle 27 is removably arranged on the container 21 at the lower end of the handle as shown in FIG. 4, the handle will not be accidentally detached from the container when the powder sieve is used.

Effects of the Invention As described above, the present invention accommodates and fixes a motor, battery, switch, etc. in the handle, and detachably engages the handle with the container, thereby making it possible to wash the container and the sieve as a whole. By recessing the lower end surface of the handle more than the lower end surface of the container in this state, the handle can be removed with one touch on the table, making it easy to use.
