Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a structure of an electric cooking machine.

[0002]

2. Description of the Related Art A conventional electric cooker, for example, as shown in FIG. 10, has a drive connector 4 attached to an output shaft 3 of an electric motor 2 incorporated in a main body 1 via a driven connector 6 provided in a cooking container 5. In a configuration for cooking food by rotating the cooking tool 7, an intake port 8 provided on the bottom surface of the main body 1 and an exhaust port 9 provided around the output shaft 3 are provided, and provided on the outer peripheral edge of the drive connector 4. By the rotating action of the exhaust fan 10, the hot air from the electric motor 2 is discharged to the outside of the main body 1 as indicated by the arrow in the figure.

However, according to the above construction, the exhaust port 9 is provided when the cooking container 5 is removed from the main body 1.
There is a problem that water and the like accidentally spilled into the main body 1 from the portion of (1) and (2) adversely affects the electric cooker.

[0004]

SUMMARY OF THE INVENTION In view of the above problems of the prior art, it is an object of the present invention to provide an electric cooker having an intake / exhaust structure in which water is less likely to enter the main body through an exhaust port.

[0005]

In order to solve the above-mentioned problems, the electric cooker according to the present invention closes the exhaust port when the drive connector is stopped and closes the exhaust port when the drive connector is rotated by centrifugal force generated by the rotation. A shutter member for opening the exhaust port is provided.

As a result, since the shutter member closes the exhaust port when the drive connector is stopped, it is possible to prevent water from entering the main body through the exhaust port, and when the drive connector rotates, the centrifugal force generated by the rotation. Thus, the shutter member opens the exhaust port and exhausts from the exhaust port, so that hot air generated by the electric motor can be discharged to the outside of the main body.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The object of the present invention can be achieved by making the configurations described in the claims as embodiments.

That is, according to the first aspect of the present invention, the driving tool provided on the output shaft of the electric motor built into the main body rotates the cooking tool through the driven connector of the cooking container to rotate the cooking tool around the output shaft. And an exhaust port formed between the main body and a portion of the main body that faces the output shaft. The exhaust port is operated by an exhaust fan that sucks air from the intake port provided in the main body and rotates with the rotation of the drive connector. A structure in which a shutter member is provided for exhausting air in the main body, and for the drive connector to close the exhaust port when the drive connector is stopped and to open the exhaust port by the centrifugal force generated by the rotation when the drive connector rotates Since the shutter member closes the exhaust port when the drive connector is stopped, it is possible to prevent water from entering the main body through the exhaust port,
When the drive connector rotates, the shutter member opens the exhaust port by the centrifugal force and the air in the main body can be exhausted from the exhaust port.

Therefore, in the invention according to claim 1,
The shutter member means a member that can open the exhaust port by centrifugal force when the drive connector rotates and closes the exhaust port when the drive connector is stopped, without specifying its form.

According to a second aspect of the present invention, in the configuration of the first aspect, the shutter member is moved in the radial direction of the output shaft of the electric motor by the centrifugal force generated by the rotation of the drive connector to open the exhaust port. It is configured.

By moving the shutter member in the radial direction of the output shaft, which is the same direction as the direction in which the centrifugal force generated by the rotation of the drive connector directly acts, the centrifugal force can be efficiently used for the movement of the shutter member.

According to a third aspect of the present invention, in the configuration of the second aspect, the shutter member is formed by combining a plurality of pieces.

Since the shutter member for opening and closing the exhaust port can be divided into a plurality of combined pieces, the movement amount of the shutter member can be increased and a larger opening for exhaust can be obtained.

According to a fourth aspect of the present invention, in the configuration of the first aspect, the shutter member is made of a material having rubber elasticity.

Since the shutter member is made of a material having rubber elasticity, the shutter member itself can be deformed by its elasticity to close or open the exhaust port, thus simplifying the structure of the shutter member itself. It can be manufactured at low cost.

According to a fifth aspect of the present invention, in the structure of the first aspect, the shutter member is moved in a direction parallel to the output shaft of the electric motor by the centrifugal force generated by the rotation of the drive connector to open the exhaust port. It is something that is done.

Since the shutter member is moved in the direction parallel to the output shaft to open or close the exhaust port, the exhaust passage itself can have a simple structure and the exhaust resistance can be reduced.

According to a sixth aspect of the present invention, in the fifth aspect, the shutter member is made of a material having rubber elasticity.

The shutter member made of a material having rubber elasticity opens and closes the exhaust port by moving it in a direction parallel to the output shaft, so that the shutter member is moved in the radial direction of the output shaft. A large movement amount of the shutter member can be obtained for the same centrifugal force.

According to a seventh aspect of the present invention, in the structure of the first aspect, the shutter member is integrally provided with an exhaust fan.

Since the shutter member is integrally provided with the exhaust fan, the structure of the entire drive connector including the shutter member and the exhaust fan can be simplified.
