Abstract

PURPOSE:To suppress a noise at the time of using a mixer by forming a through hole for allowing an annular space and the inside of a bottle to communicate with each other on a cylindrical part, and forming a communicating hole for allowing the annular space and the outside to communicate with each other in a position separated from the through hole of a collar part. CONSTITUTION:An annular space surrounded by the inside surface of a bottle 4, a collar part 9, a cylindrical part 10 and a sealing part 11 is formed. A through hole 13 which is formed in the cylindrical part 10 and allows the inside of the bottle 4 and the annular space 12 to communicate with each other is formed to an area being smaller than a cross section of the annular space 12. A communicating hole 14 which is formed in the collar part 9 and allows the annular space 12 and the outside to communicate with each other is formed in a position separated most from the through hole 13, and this communicating hole 14 is formed smaller than the cross section of the annular space 12. Accordingly, a water flow sound generated by the convection of a material passes through the through hole 13 and reaches the annular space 12, passes through the long annular space 12 and is leaked to the outside from the communicating hole 14. In such a manner, the leakage of a noise to the outside is suppressed.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a mixer for making juice by cutting and mixing materials such as fruits.

(b) Conventional technology In this type of mixer, during operation, the material is flushed with the liquid,
This water sound leaked through the air vent hole formed in the lid and was the main cause of noise.

In order to solve this deficiency α, Utility Model Publication No. 62-21258 (\i7J 43104) was proposed. In other words, the lid body that covers the part between the upper surfaces of the bottle is composed of an outer lid and an inner lid that can move up and down with respect to the outer lid, so that when the pressure inside the bottle increases during the first operation, the inner lid moves upward. The air inside the bottle rises up and is discharged through the through hole formed in the inner lid. When the air escapes to the outside, the pressure inside the bottle decreases and the inner lid lowers, and the through hole in the inner lid closes, causing the sound of water flowing outside.・Designed to prevent leakage of ＼.

However, this configuration requires an outer cover and an inner cover, which has the disadvantage of complicating the structure.

(c) Problems to be Solved by the Invention The present invention has been made in view of the above drawbacks, and an object thereof is to provide a mixer that can reduce noise with a simple configuration.

Means for Solving the Problems The bottle includes a cutter that is rotatably driven by a drive means, and a lid that covers the top opening of the bottle, and the lid includes a flange that comes into contact with the top edge of the bottle; A cylindrical portion that fits loosely into the inner surface of the bottle and a seal portion that abuts the inner surface of the bottle are formed to form an annular space surrounded by the cylindrical portion, the flange, the seal portion, and the inner surface of the bottle. It is characterized by forming a through hole that communicates with the inside of the bottle, and also forming a communicating hole that communicates between the annular space and the outside at a position spaced apart from the through hole in the flange.

(e) The air in the working bottle is exhausted to the outside through the through hole, the annular space, and the communication hole.

On the other hand, water sound generated by convection of the material reaches the annular space through the through hole and leaks to the outside from the communication hole through the long annular space, so leakage to the outside is suppressed.

(F) Embodiment An embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 3.

1 is a main body that houses an electric motor 2, and has an opening formed on the top surface;
The output shaft 2a of the electric motor 2 passes through this opening and extends upwardly.
\It has been extended. 3 is a coupling attached to the tip of the output shaft 2a.

Reference numeral 4 denotes a bottle placed on the main body 1, and has a rotary shaft 5 rotatably supported approximately at the center of the bottom surface. A coupling 6 is attached to the lower end of the rotating shaft 5, and this coupling 6 is engaged with the coupling 3 to transmit the rotation of the electric motor 2 to the rotating shaft 5. 7 is the rotating shaft 5
- This is a cutter attached to the E end.

Reference numeral 8 denotes a lid made of synthetic resin that covers the top opening of the bottle 4, and includes a flange 9 that comes into contact with the edge of the top opening of the bottle 4, a cylindrical part 10 that fits loosely into the bottle 4, and a cylindrical part 10. It has a seal portion 11 that is formed toward the outer periphery and has an outer periphery in contact with the inner surface of the bottle 4 . An annular space 12 is defined by the inner surface of the bottle 4, the flange part 9, the cylindrical part 10, and the seal part 11. Reference numeral 13 denotes a through hole formed in the cylindrical portion lO, which communicates the inside of the bottle 4 with the annular space 12;
3 is formed to have an area smaller than the cross-sectional area of the annular space 12. A communication hole 14 is formed in the flange 9 and communicates the annular space 12 with the outside, and is formed at the farthest position from the through hole 13 (see FIG. 2).
4 is formed smaller than the cross-sectional area of the annular space 12.

Therefore, liquids such as water and milk and materials such as fruits are placed in the bottle 4.
When the electric motor 2 is driven, the pressure inside the bottle 4 increases at the beginning of operation, but the air inside the bottle 4 flows through the through hole 1.
3. The air is exhausted to the outside through the annular space 12 and the communication hole 14.

On the other hand, water flow noise caused by material convection is caused by narrow through holes 1
3, it reaches a wide annular space 12, goes halfway around the annular space 12, and leaks to the outside through a narrow communication hole 14, so that it passes alternately through narrow spaces and wide spaces, and passes through a long annular space 12. By doing so, it is possible to greatly attenuate and significantly reduce leakage to the outside.

Further, even if the juice layered above the bottle 4 passes through the through hole 13 together with the air, the juice will not jump out to the outside because the annular space 12 is formed long.

In addition, in the above embodiment, the communication hole 14 is approximately 18 mm in diameter with the through hole 13.
Although the through holes 13 are formed at different positions by 0', as shown in FIG.

Furthermore, by forming a plurality of ribs 15 from the cylindrical portion 10 toward the outer periphery to near the inner surface of the bottle 4 as shown in FIG. 4, and partitioning the annular space 12 into a plurality of narrow spaces and narrow spaces,
Leakage of water flow sound can be further suppressed.

(g) Effects of the Invention As described above, according to the present invention, it is possible to suppress leakage of water flow sound to the outside with a simple structure, and it is possible to suppress noise when the mixer is used.
