Description

[Detailed description of the invention] The present invention relates to a coffee mill for grinding roasted coffee beans into powder.In particular, when the lid is open, the electric motor is driven and the rotary blades do not rotate even if the power switch is pressed. It's something I did.

Referring to the drawings below, reference numeral 1 denotes a mechanical part 3 containing an electric motor 2 of the coffee mill main body, and a bean grinding part 6 forming a storage chamber 5 in which a rotary blade 4 connected to the electric motor 2 is provided.
and a lid body 8 which covers the upper surface opening 7 of the bean grinding part 6 in an openable and closable manner.

A compartment 9 is formed in the bean grinding section 6 adjacent to the storage chamber 5, and a support section 10 having a U-shaped cross section is integrally formed on the bottom wall of the compartment 9.

A sliding body 12 having a pressing piece 11 is disposed in the support part 10 so as to move up and down, and a swinging rod 14 is attached to the sliding body 2 via a first shaft 13, so that the inside of the support part 10 can be moved up and down. It is said that

A spring 15 is wound around the pressing piece 11 to constantly urge the swinging rod 14 upward together with the sliding body 12.

An operating rod 1 is connected to one end of the swing rod 14 via a second shaft 16.
7 is set upright so that its tip 18 always protrudes beyond the upper step 19 of the storage chamber 5, and the lid body 8 is placed on the upper step 19 to cover the upper surface opening 7. sometimes,
The operating rod 17 is pressed downward by the lid 8.

Further, a horizontal portion 20 is integrally formed at the other end of the swinging rod 14, and a pressing rod 21 whose tip abuts on the horizontal portion 20 is erected, and the other end of the pressing rod 21 is connected to the bean grinding portion. It protrudes from 6 and is connected to the power switch section 22.

Further, an opening/closing contact 23 for driving the electric motor 2 is disposed below the pressing piece 11, and when the pressing piece 11 is pressed downward, the opening/closing contact 23 closes and the electric motor 2 is driven. It is.

24. 24 is a lead wire that electrically connects the electric motor 2 and the drive switching contact 23.

According to such a configuration, the power switch 22 can be operated without placing the lid 8 on the top opening 7 of the bean grinding section 6 as shown in FIG.
Even if the swinging rod 14 is pressed by hand in the direction of the arrow, the spring 1
5, the pressing piece 11 is also located above, and this pressing piece 11 does not close the opening/closing contact 23, and as a result, the electric motor 2 is not driven.

Therefore, even if the user falls down and presses the power switch 22 with his/her hand inside the storage chamber 5, the rotary blade 4 will not rotate and no injury will occur.

Also, as shown in FIGS. 4 and 5, the lid 8 is first placed in the storage chamber 5.
When placed on the upper step 19 so as to cover the upper opening 7, the lower end of the lid 8 keeps the operating rod 17 pressed downward, and when the power switch 22 is then pressed, the pressing rod 21 is pushed downward. As a result, the swinging rod 14 descends downward, the sliding body 12 also descends downward, the pressing piece 11 is pushed down against the spring 15, and the driving switching contact 23 closes. As a result, the electric motor 2 is driven and the rotary blade 4 is rotated to grind coffee beans.

Since the present invention is constructed as described above, if the lid is not placed so as to cover the top opening of the coffee mill, the rotary blade will not rotate even if the pressing rod is pressed, and the lid will fall. Even if you press the pressure rod and bring your hand close to the rotary blade without placing it, the rotary blade will not rotate and there is no risk of injury, providing a coffee mill with excellent safety. be.

Claims (1)

[Scope of utility model registration request] In a coffee mill that is equipped with an electric motor that drives a rotary blade and whose top opening is covered with a lid, there is provided an operating rod that is lowered by the covering of the lid, a pressing rod that is manually lowered, and a connection between the operating rod and the pressing rod. A swinging rod that is capable of moving up and down in conjunction with both ends thereof is installed therein, a pressing piece is connected to the swinging rod, and an opening/closing contact for driving the electric motor is arranged, which is closed by the descent of the pressing piece. A coffee mill characterized in that the swinging rod is lowered when the operating rod and the pressing rod are lowered simultaneously.
