Description

Detailed Description of the Invention The present invention relates to a cooker that stirs vegetables and liquids with a cutter.In particular, by improving the shape of the upper and lower rotation transmission joints, the power transmission is reliable and the switch can be operated intermittently. "
To provide a safe cooker in which a container and a container lid do not fly off even when turned on or off.

An embodiment of the present invention will be described below based on the drawings.

In the figure, reference numeral 1 denotes a main body with a built-in electric motor 2, and the electric motor 2 is fixed between a rib 1b of the main body 1 and a back plate 16 via two cushion rubbers 15 and a mounting plate 3.

Legs 17 are fixed to the back plate 16. A switch 13 for driving the electric motor 2 is attached to the mounting plate 3, and a coil spring 14 pushes the switch plate 12 upward.

The switch plate 12 is provided with a switch operation rib 12a at a position facing the switch 13.

A container 5 is placed on the upper part of the main body 1, and inside the container 5, a cutter unit 6 is provided, which is formed by forming two cutters 6a with a step.

The cylindrical container lid 4 that covers the upper opening and outer side of the container 5 forms a transparent lid 18 on the upper surface and has several protrusions 4 on the inner periphery.
The container 5 and the container lid 4 are removably fitted between the recess 5a and the recess 5a on the outer periphery of the upper portion of the container.

Moreover, an elastic body 19 such as rubber is interposed between the upper inner periphery of the container lid 4 and the lid 18, and when the container 5 is fitted to the container lid 4, the upper inner periphery and outer periphery of the container 5 are The rib portions of the elastic body 19 are in close contact and seal.

One cutter 6 is detachably attached to a main shaft 7 held via a bearing 8 fixed to the container 5 and an oil seal 9.

An upper rotation transmission joint 10 made of an elastic material such as rubber is fixed to the lower end of the main shaft 7, and the upper rotation transmission joint 10 is fitted into the inner circumference of a lower rotation transmission joint 11 fixed to the shaft 2a of the electric motor 2. ,
The rotation of the electric motor 2 is transmitted to one cutter 6 via the main shaft 7.

The lower end of the container lid 4 is provided with two or more protrusions 4b for operating a switch, and the upper surface of the main body 1 is provided with a switch hole 1a at a position opposite to the protrusions 4b for operating a switch.

At the bottom of the switch hole 1a, a switch plate 12 is pressed against the ceiling surface of the main body by a coil spring 14 in order to close the switch hole 1a.

Next, the operation and operation of the cooking device will be explained.

First, a cutter unit 6 is fitted to the main shaft 7 inside, a container lid 4 is fitted to the container 5 containing the object to be cut, and when placed on the main body 1, the rotation transmission joint 10.11 made of an elastic body Fit slightly.

Next, a protrusion 4 for operating a switch provided at the lower end of the container lid 4
When b is aligned with the switch hole 1a provided on the top surface of the main body 1 and the container lid 4 is pressed downward (as shown in Fig. 1), the switch hole 1a
The protrusion 4b for switch operation presses down the operation part 12b of the switch plate 12 through the switch plate 12 against the reaction force of the spring 14, so that the switch operation part 12a
closes the contact of the switch 13, and electric power is supplied to the electric motor 2, causing it to rotate.

One cutter 6 rotates via the lower rotation transmission joint 11, the upper rotation transmission joint 10, and the main shaft 7, and the object to be cut is cut and stirred by the cutter 6a.

When stopping the operation, the coil spring 14 pushes up the switch plate 12 by removing the pressure applied to the container lid 4, and the container 5 also lifts up, opening the contacts of the switch and cutting off the power to the motor 2, stopping rotation.

The upper rotation transmission joint 10 and the lower rotation transmission joint 11 are configured so that during rotation transmission, the inner part of the lower rotation transmission joint 11 and the outer part of the upper rotation transmission joint 10 slide in the vertical direction.
Particularly when the workpiece to be cut is small and has a light load, the upward force of the coil spring 14 is large except for the suppression of the container lid 4, so the inertia of the rotation of the electric motor 2 causes the container 5 and the container lid 4 to move upward. It rotates even when pushed up.

Therefore, the fit between the vertical rotation transmission joints 10 and 11 is shallow.

In addition, due to eccentricity of the upper end of the lower rotation transmission joint 11, etc., the center of rotation with the upper rotation transmission joint 10 tends to shift, causing problems such as the container 5 and container lid 4 being shaken on the main body 1 and falling from the top of the main body. occurs.

However, as shown in FIGS. 3 and 4, the upper rotation transmission joint 10 made of an elastic material such as rubber is provided with an upper stopper 10a in the vertical direction on its outer periphery, and the shape of this is reversed so that the lower part is wider. Even if the suppression of the container lid 4 is removed, the sliding resistance between the lower rotation stopper part 11a on the inner side of the lower rotation transmission joint 11 and the upper rotation transmission joint 10 increases, and the coil spring 14 is Even if the restoring force is large, the container 5,
Since the container lid 4 rises slowly, the vertical rotation transmission joint 1
When the fitting between 0 and 11 is shallow, the rotation is stopped or at a low rotation rate.

Therefore, the fitting between the switch hole 1a and the switch operation projection 4b does not come off, and the container 5 and container lid 4 are not swung around on the main body 1, making it safe.

In other words, even if the switch 13 is turned on and off, the container 5
, the container lid 4 will not fly off.

In addition, by making the central lower end of the upper rotation transmission joint 10 made of an elastic body hollow, the diameter expands due to centrifugal force during rotation, and the sliding resistance between the inside of the lower rotation transmission joint 11 and the upper rotation transmission joint 10 is further reduced. There is something called a dog that increases the effect.

Furthermore, if a protrusion 11b is provided at the center of the lower rotation transmission joint 11 and the protrusion 11b is fitted into the hollow part of the upper rotation transmission joint 10, the fitting of the upper rotation transmission joint 11 becomes more stable.

As described above, in the present invention, by improving the shape of the upper and lower rotation transmission joints, the two can be reliably fitted and safety can be ensured.
