Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electric meat grinder for general household and commercial use.

(Prior Art) Conventionally, this type of electric meat grinder is composed of a drive section 1 having a built-in electric motor 2 and a reduction gear 3, and a cylindrical meat grinding section 4, as shown in FIG. 3, for example. .
Although not shown, a screw unit, a rotary cutter, and a fixed cutter are provided inside the meat grinder 4.

The opening of the meat grinding section 4 is closed with a cover body 5 which is detachably attached by screw fitting, and by tightening the cover body 5, the rotary cutter and the fixed cutter are pressed together.

(Problems to be Solved by the Invention) In the above configuration, after the electric motor is operated to grind meat, the screw unit, rotary cutter, and fixed cutter inside the meat grinder 4 contain oil, fat, and scraps. Because of this, it is necessary to rotate the cover body 5 in the return direction, remove it from the meat grinder 4, take out the above-mentioned parts, and wash them.

However, since the threaded portion between the cover body 5 and the minced meat part 4 usually has 4 to 5 threads, the cover body 5
In order to remove the cover body 5, it is necessary to turn the cover body 5 four or five times, which is rather troublesome. In addition, the cover body 5 may have oils and fats attached to it, which causes the cover body 5 to easily slip, which poses a major problem in that attachment and detachment of the cover body 5 is even more complicated and time-consuming.

Therefore, the present invention was invented to solve the above-mentioned problems, and its purpose is to provide an electric meat grinder whose cover body can be removed quickly and accurately with a single touch operation. .

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a spiral spring around the outer periphery of the meat grinder, one end of which locks the meat grinder, and the other end of the spiral spring. The end is hooked onto a rib body protruding from the cover body, and the rib body can be engaged with a locking rod provided on the meat grinding section side, and the locking rod is connected between the rising walls on the meat grinding section. It is pivotably mounted using a pin and is normally biased to the upright position by a spring.

(Function) In the above means, when the cover body is tightened to the opening of the meat grinder, the helical spring is tightened and elastic energy is stored.

This elastic energy is retained by engaging the rib body with a locking rod provided on the meat grinder side.

Accordingly, when the cover body is removed from the meat grinder, the locking rod is swung backward against the spring to disengage the rib body from the locking rod.

Then, the cover body is instantaneously rotated in the return direction by the elastic energy stored in the helical spring, and is removed from the meat grinder.

(Example) An example of the present invention will be described below based on the accompanying drawings.

In FIGS. 1 and 2, reference numeral 11 denotes a drive section, which incorporates an electric motor 12 and a speed reduction device 13.

A substantially cylindrical minced meat part 14 is provided at the front of the drive part 11 in a detachable manner. Although not shown, a removable screw unit is disposed within the meat grinder 14, and a substantially cross-shaped rotary cutter and a fixed cutter with a large number of round holes are attached to the shaft of the screw unit.

The front side opening of the meat grinding section 14 is closed with a cover body 15 which is detachably attached by screw fitting, and by screwing this cover body 15 into the opening of the meat grinding section 14, the meat grinding section 14 can be opened. The screw unit, the rotary cutter, and the fixed cutter set in the cutter 14 are configured to be tightened and fixed.

Further, on the outer periphery near the opening end of the minced meat part 14,
A helical spring 16 is provided, one end 16a of which is engaged with the minced meat part 14, and the other end 16b of which is hooked onto a rib body 15a protruding from the cover body 15.

The spring 16 is wound up by tightening the cover body 15 to the opening of the meat grinder 14 to store elastic energy, and the outer periphery of the spring 16 is formed by a rotatable spring receiver 17. Surrounded. Note that the other end 16b of the spring 16 is
Projecting from an opening formed in the spring receiver 17,
It is adapted to be hooked onto the rib body 15a of the cover body 15.

The rib body 15a can be engaged with a locking rod 18 provided on the side of the meat grinder 14, and the rib body 15a
By engaging with the locking rod 18, the cover body 15 is locked to the minced meat portion 14. This locking rod 18 is pivotally connected to the standing walls 19, 19 on the minced meat part 14 by a pin 20, and is normally urged to the upright position by a spring 21. . In addition, 18a in the figure is a regulation projection when the locking rod 18 is in the upright position.

Since the present invention has the above-described configuration, by screwing the cover body 15 into the threaded part of the opening to attach it to the minced meat part 14, the helical spring 16 is wound and elastic energy is stored. . By engaging the rib body 15a of the cover body 15 with the locking rod 18 on the side of the meat grinder 14, attachment of the cover body 15 to the meat grinder 14 is locked. In this state, the meat is ground as appropriate, and when the meat grinding is finished, the locking rod 18 is swung backwards against the spring 21, and the rib body 1
5a is disengaged from the locking rod 18.

Then, the cover body 15 is instantaneously rotated in the return direction by the elastic energy stored in the helical spring 16, and is removed from the meat mincer part 14.

(Effects of the Invention) As described above, the present invention provides a cover body that is screwed and held in the front part of the meat grinder, a spiral spring is arranged between the two, and one end of the cover body is latched to the meat grinder. let me,
Hang the other end on the rib body that protrudes from the cover body,
By tightening the cover body, a helical spring is wound up and elastic energy is stored.Furthermore, it can be engaged with a locking rod provided on the meat grinding part side of the rib body. The stop rod is pivotally mounted between the upright walls on the meat grinder section with a pin, and is normally biased to the upright position by a spring.

Therefore, after grinding the meat, by unlatching the cover body to the meat grinding part side, the cover body is instantly loosened by the above-mentioned elastic energy, and the cover body can be turned 4 to 5 times by hand. This eliminates complicated and troublesome efforts such as
