Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to electronic switches for cooking appliances such as juicers, mixers and speed cutters.

Conventional structure and problems Juicers and mixers have traditionally been used as electric cooking machines to make juice by cutting ingredients with a knife.

Or there's a speed cutter that prepares food for cooking.

FIG. 3 shows a perspective view of the juicer.

A conventional juicer of this kind has a built-in electric motor (
A cutter (not shown) is driven, and the material is fed into the cutter (not shown) which is rotated at high speed by the electric motor through the input port 4a provided in the lid 4, and the material is fed into the push rod 5. By pushing the material X1, the juice is squeezed out and stored in the custom word 6. However, since the material is cut using a cutter that rotates at high speed, safety is an extremely important issue.
It was common to have a safety mechanism that enabled the switch 3 to operate.

On the other hand, since the structure of the switch 3 is conventionally mechanical, it is also possible to place it on the same plane as the main body 2 as shown in Fig. 4.
It was not possible to eliminate the gaps, and problems such as difficulty in cleaning and deterioration of insulation were caused when juice or water got on the circuit. A structure in which the surface 7 and the surface 8 are provided is considered.

Generally, devices equipped with an electronic switch 7 are equipped with a separate mechanical lock type power switch (not shown), and if this U switch is not turned on, the operation Fi of the electronic switch 7 will be disabled. The safety of the machine BR is ensured.

However, when this configuration is applied to a juicer, one power switch is required in addition to the conventional one, so when operating it, the power switch must be turned on and then the electronic switch 7 must be operated. There were two important cost issues.

Purpose of the Invention The present invention solves the above-mentioned conventional problems, and ensures the safety of the equipment without providing a switch such as a mechanical lock type power switch other than an electronic switch, and the operation method is also the same as the conventional one. The present invention provides an electronic switch for a cooker.

Structure of the Invention In order to achieve the above object, the electronic switch for the cooker of the present invention uses an electric contact interlocked with a clamp used as a safety mechanism as a switch for supplying power to the circuit section and the electric motor. The operation method is the same as the conventional one, so that the device can be operated only by operating an electronic switch after clamping, thereby maintaining the safety of the device.

DESCRIPTION OF EMBODIMENTS FIG. 1 shows a sectional view of a juicer according to an embodiment of the present invention, and FIG. 2 shows a block diagram of a circuit.

In Figure 1, what works the same as in Figure 3 -
C is given the same reference numeral, and the description thereof will be omitted here.

In FIGS. 1 and 2, reference numeral 10 denotes a printed circuit board (hereinafter referred to as a switch board) on which circuit components constituting an electronic switch are mounted, and is provided within the main body 2, although not shown. This switch board 10 includes an electronic switch 1
4, the fixed side electrical contact person 11, and the electrical contact A11.
An electric contact B12 on the movable side is provided on the elastic plate.

On the other hand, a contact actuating member 13 is coupled to a rotary support rod 15 that is pivotally connected to the main body 2 and supports the clamp 1.
The contact actuating member 13 is configured to rotate following the rotation. This contact operating member 13 is connected to the electrical contact A11. It is related to the operation of B12.

In the above configuration, when the device is not used, the clamp 1 is generally removed from the container lid 4, so the electrical contacts A11 and B12 are open as shown in Figure 1, and the switch board 1Q is No power is supplied to the electronic switch 14, so the operation of the electronic switch 14 is invalid and the motor remains stopped. When using the equipment,
Clamp 1 is clamped to container lid 4. Then, the contact actuating member 13 interlocked with the clamp 1 moves in the direction of ■ to close the electric contact 11 and the electric contact B12, so power is supplied to the switch board 1Q, enabling circuit operation, and allowing the electronic switch 14 to be operated. The electric motor can be controlled accordingly.

-i Furthermore, if the clamp 1 is removed while the electric motor is rotating, the electric contacts A11 and B12 open, so the electric motor automatically stops and the operation of the electronic switch 14 is also disabled.

Note that if the lamp is turned on when the electrical contact A11 and the electrical contact B12 are closed, the state of the contacts can be easily checked from the corner of the eye.

Furthermore, although the present embodiment has been described using a juicer as an example, the same applies to other household cooking appliances such as mixers and speed six-wheelers.

Effects of the Invention As is clear from the description of the above embodiments, the cooking +!

By using a moved contact actuating member, the operation method is no different from the conventional one, and the mechanical lock type power switch that was previously required for devices equipped with electronic switches is no longer necessary. This has the effect of ensuring sufficient safety for machine 2g.

Moreover, by using an electronic switch, the switch part can be protected with a top sheet, cleaning becomes easier, and safety can be ensured from the standpoint of insulation, which is not to be overstated.
