Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a flour sifter for sifting flour such as flour at home, and furthermore, to a flour sifter that also serves as a strainer for soup, etc.

Prior Art The applicant previously filed a utility model registration application for a device related to a powder sieve as Utility Model Application No. 41148/1983. This powder sifter has a main body with a mesh stretched over a frame, and a rotating body with blades extending in the radial direction of the main body.
The blade is rotatably attached while contacting the mesh, and the surface of the blade facing the mesh is a flat surface, and a plurality of small protrusions are provided on the surface. This powder sieve was excellent in that it did not easily clog and had good sieving efficiency.

Furthermore, the main body of this powder sifter can also be used as a strainer by removing the rotating body.

Problems to be solved by the invention However, in the powder sieve with the above structure,
Once used as a strainer, the sieving efficiency was significantly reduced when used as a flour sieve.

That is, when the device is used as a strainer,
When exposed to a high temperature atmosphere or when hot soup is strained, the difference in thermal expansion coefficients between the frame and mesh may cause slight misalignment between the mounting parts of the two.
The mesh becomes loose. Once the mesh has loosened in this way, when using it as a flour sieve, the small protrusions on the rotating body will not contact the mesh properly and the mesh will not vibrate properly even when the rotating body is rotated, so make sure to thoroughly remove the powder. It becomes impossible to sieve.

The present invention was devised in view of the above circumstances, and the purpose is to provide a flour sifter that can be used as a strainer and which can efficiently sift powder without loosening the mesh even after being used as a strainer. It is something.

Means for Solving the Problems The powder sifter of the present invention has a main body with a mesh stretched over a frame, and a rotating body having blades extending in the radial direction of the main body, which can be attached and detached so as to be able to rotate while contacting the mesh. In those that can be installed,
It is characterized in that a stepped groove concentric with the frame is formed near the outer periphery of the mesh.

The present invention will be explained below with reference to the drawings. 1st to 3rd
The figure shows a powder sifter 1 of the present invention. Reference numeral 2 denotes a main body, which is a circular frame 3 with a mesh 4 stretched over it, and a handle 5 is formed on the outer periphery of the frame 3. An edge 6 is formed on the inner periphery of the frame 3, and the mesh 4 is fixed to the lower surface of the edge 6. Two locking protrusions 7 are provided slightly above the edge 6.

Reference numeral 8 denotes a rotating body, and a circular ring 9 is provided with radial blades 10, and a knob 11 is attached to one of the blades 10. The blade 10 has a flat lower surface 12 facing the mesh 4, and has a substantially triangular prism shape consisting of the lower surface 12 and two surfaces 13 and 14 that form an acute angle with respect to the lower surface 12. A plurality of small protrusions 15 are provided protrudingly. Note that some of the small protrusions 15 are located outside of the stepped grooves 18, which will be described later.

Further, the ring 9 is formed with notches 16 at two places, and the notches 16 are fitted into the locking protrusions 7 of the main body 2 to place the ring 9 on the edge 6, and the knob 11 is placed on the ring 9. The rotating body 8 can be rotated by gripping the rotating body 8. 17 is a container for storing the sifted powder.

In the present invention, a stepped groove 18 concentric with the frame 3 is formed near the outer periphery of the mesh 4.

Function To use the flour sieve 1 of the present invention for its intended purpose, the main body 2 is combined with the rotating body 8, and the flour sieve 1 is placed on the container 17. Then, the powder is placed on the powder sieve 1, and the rotating body 8 is rotated relative to the main body 2 by grasping the knob 11. As a result, the blade 10 stirs the powder on the mesh 4, and the small protrusion 15 protruding from the lower surface 12 of the blade 10
rotates while contacting the mesh 4, vibrating the mesh 4, and sieving the powder on the mesh 4 into the container 17.

When using this as a strainer, the rotating body 8 is removed from the main body 2, and the soup or the like is poured onto the mesh 4 and strained.

Therefore, in the present invention, even if heat is applied to the main body 2 when straining hot soup etc. and a large tensile force is applied to the mesh 4 due to the difference in coefficient of thermal expansion, the stepped grooves 18 absorb the tensile force. Metsuyu 4
There is no misalignment between the mesh 4 and the frame 3, and when it cools down, the mesh 4 becomes taut again and will not loosen.

Also, even if the mesh 4 becomes somewhat loose,
The loosening is mainly concentrated in the part inside the stepped groove 18, and the mesh 4 in the area between the stepped groove 18 and the frame 3 hardly loosens. Therefore, when using it as a powder sieve again, the small protrusions 15 of the rotating body 8 should be securely attached to the mesh 4 on the outside of the stepped grooves 18.
Since the mesh 4 comes into contact with the mesh 4 and vibrates, the vibration is transmitted to the entire mesh 4, and the powder can be sieved sufficiently.

Effects of the invention According to the invention, as mentioned above, the small protrusions 15 of the blades 10 vibrate the mesh 4, and the vibration sieves the powder, so the efficiency of sifting the powder is extremely high, and the sieving can be done quickly and cleanly. In addition, the mesh hardly loosens even after being used as a strainer, and even if it loosens to some extent, the powder sieving efficiency does not decrease and the mesh can be sieved satisfactorily.
