Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric flour sieve for sieving 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 directly immerse the sieve and container in water to wash them because the motor, battery, etc. are fixed inside the container, and as a result,
The drawback was that it was unsanitary.

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 and fixes a motor, battery, switch, etc. in a handle, rotatably attaches a sieve to a support in a container, A substantially U-shaped rib is formed on a part of the outer periphery, an eccentric shaft is fixed to the motor shaft of the motor, and the handle is detachably attached to the container so that the eccentric shaft fits into the gap between the substantially U-shaped ribs. The lower end surface of the handle is formed to match or protrude from 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 amount of eccentricity of the eccentric shaft is changed. The sieve was made to vibrate with twice the amplitude.

Function By removing the handle containing the motor, battery, and switch from the container, the sieve and container can be soaked in water and washed. In addition, the fitting direction of the handle and the container is set in a direction opposite to the sieving direction of the powder, taking into consideration the state of use, so that the handle will not come off due to the weight of the powder etc. during use.

In addition, as mentioned above, when the handle is fitted into the container, the lower end of the handle is aligned with or protrudes from the lower end of the container, so even if the product is placed on a table and pressure is applied from the top of the container, the handle will not move. will not come out of the container.

Embodiment Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 3.

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 integrally with the container 21 at the center where these ribs 21a are concentrated. 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 top, a battery 25 and a motor 22 are housed and fixed inside, and a positive lead 29, a switch 26, a minor lead 34, and a common lead 35 are used to connect the battery 25.
and the motor 22 are connected. 38 is battery 2
This is the lid of the battery compartment that houses the battery. An eccentric shaft 32 is fixed to a motor shaft 31 of the motor 22.
Then, a pawl 36 formed on a part of the handle 27 is attached to the container so that the eccentric shaft 32 fits into the gap of the substantially U-shaped rib 28 formed on a part of the outer periphery of the sieve 24.
A fitting hole 37 bored in a protrusion protruding from the outside of 1
The handle 27 and the container 21 are integrally fitted together. The positional relationship between the pawl 36 and the fitting hole 37 is set such that the lower end surface A of the handle 27 coincides with or protrudes from the lower end surface A of the container 21 in the fitted state.

The substantially U-shaped rib 28 and the eccentric shaft 32 are connected to the sieve 24.
They fit together with a slight gap in the direction of rotation, and with a free gap in the direction perpendicular to the direction of rotation. Therefore, the switch 26 is closed and the battery 2
5 is supplied to the motor 22, the eccentric shaft 3
2 rotates integrally with the motor shaft 31 and slidingly contacts the inner wall of the substantially 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, the handle 27 is removed from the container 21 by pressing the claw 36 with a finger in the direction of arrow A and lowering the handle 27 in the direction of arrow B. Handle 2
The container 21 with the 7 removed can be washed with water together with the sieve 24.

By arranging the attachment/detachment direction of the container 21 and the handle 27 opposite to the sieving direction as in the present invention, the container 21
Due to the weight of the powder in the container 1, the handle 27 will not be detached from the container 21 during use.

Further, as mentioned above, since the lower end surface of the handle 27 is made to protrude beyond the lower end surface of the container 21, the handle 27 will not come off from the container 21 when placed on the table, and will not stick to the lower part of the inner wall of the container 21. Powder does not stick to the table.

Effects of the Invention As described above, according to the present invention, the motor, the battery, and the switch part are housed in the handle, the handle is removably fitted into the container, and the lower end surface of the handle is aligned with the lower end surface of the container. Or, since it is made to protrude, it not only makes it possible to wash the container and sieve with water, but also
The handle does not come off the container even if it is used abnormally, making it very easy to use.
