Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electric cooking device for slicing or kneading food.

[Prior Art] A conventional electric cooking device uses an electric motor built in a drive unit to rotate a rotating member such as a cutter or a stirring member attached to a bottle unit, thereby slicing food placed in the bottle unit. or kneading. In the above-mentioned electric cooking device, when the lid of the bottle part is removed, the bottle switch, which is activated in response to the lid removal, cuts off the supply of driving power to the electric motor, and also restricts the electric motor to direct current, thereby reducing inertia. The rotation of a rotating member that continues to rotate due to force is stopped.

[Problems to be Solved by the Invention] However, in order to ensure the safety of the operator, in the above-mentioned conventional electric cooking device, when the lid is removed and the top opening of the container body is open, the rotating member is completely turned off. It is required that it be stopped. In order to execute the above operation in a short time, a large electric power is applied to the electric motor to restrict direct current. Specifically, the UL standard requires that the rotating member completely stop rotating within about 2 seconds after the bottle switch detects the open state of the lid. As a result, the opening/closing member or element can output a large amount of power to 0N-O in a short period of time.
FF#JmI, and these opening/closing members or opening/closing elements have the problem of being easily damaged, and it is difficult to reliably stop the rotating member when the lid is removed from the container body. Ta.

[Object of the Invention] In view of the above-mentioned conventional drawbacks, an object of the present invention is to improve the safety of the operator by stopping the rotating member that continues to rotate due to inertia force in a short time when removing the lid from the container body. The purpose of the present invention is to provide an electric cooking device that can obtain the desired results.

[Means for Solving the Problems] Therefore, the present invention provides an operating member that rotates as the lid is attached to and removed from the container body, and the operating member.

a braking member that comes into pressure contact with the rotating part of the electric motor as the container rotates, and an elastic member that normally biases the braking member so that it comes into pressure contact with the rotating part of the electric motor, and the lid is attached to the container body. When installing, the braking member is moved away from the rotating part of the electric motor against the elastic force of the elastic member as the actuating member rotates in a desired direction, while the opposite is true when removing the lid from the container body. The electric cooking device is constructed by bringing the braking member into pressure contact with the rotating part of the electric motor by the elastic force of the elastic member as the actuating member rotates in the direction.

[Operation of the Invention] Since the present invention is configured as described above, when attaching the lid to the main body of the container into which food is put, 1, the braking member resists the elastic force of the elastic member as the actuating member rotates. It is possible to release the braking stop state of the electric motor by separating it from the rotating part of the electric motor. On the other hand, when removing the lid from the container body, as the operating member rotates, the elastic force of the elastic member presses the braking member against the rotating part of the electric motor, and the rotating member connected to the electric motor is pressed against the rotating part of the electric motor. Rotation can be stopped by braking. Therefore, when the upper end opening of the container body is in the open state, the rotating member can be reliably maintained in a stopped state, and the safety of the operator can be ensured.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

When the lid 25 is attached to the container body 21 and then rotated in a desired direction, the cam 39 comes into contact with the upper end of the actuating rod 27 and pushes the actuating rod 27 downward.

FIG. 3 is an exploded perspective view of the road body showing the braking mechanism. Four support holes 9C are formed concentrically in the center of the upper motor cover 9b of the electric motor 9. A support shaft 41a integrally formed on the upper end surface of the guide 41 is inserted into the pad receiver. A ring-shaped pad receiver 43 is attached to the guide 41 of the pad receiver. A circular support recess 43a is provided on the upper surface of the pad receiver 43.
A guide portion 41b of the guide 41 is supported in the support recess 43a so that the pad receiver is movable in the vertical direction. In the pad receiver, a compression spring 45 as an elastic member is attached between the guide 41 and the pad receiver 43, and the compression spring 45 always urges the pad receiver 43 downward by its elastic force. . A braking pad 47 made of hard urethane or the like, which is a braking member, is attached to the lower end surface of the pad receiver 43 so as to come into contact with the upper end surface of the rotor 9d of the electric motor 9 in the axial direction.

A pair of hook portions 43b are formed on the outer peripheral edge of the pad receiver 43 so as to face each other. This hook portion 43b projects outward from the electric motor 9 through an opening 9e formed in the upper motor cover 9b. An actuating lever 49 as an actuating member is rotatably supported in the recess 9f provided in the upper end surface of the upper motor cover 9b about its protrusion 498 as a fulcrum. and the operating lever 49

The main power switch 3 is provided with a main power switch (not shown), and driving power is supplied to the electric motor 9 when both the main power switch and the bottle switch 13 are in the ON state.

Next, the operation of the electric cooking device 1 configured as described above will be explained with reference to FIGS. 2 and 4.

In FIG. 2, after the lid 25 is attached to the upper end opening 22 of the container main body 21 attached to the upper part of the drive unit main body 3, the lid 25 is moved along the upper end opening edge of the container main body 21, for example in a counterclockwise direction. When the lid 25 is rotated to the engaging portion 21c, the lid 25
When the engaged portion 37 of the cam 39 is engaged, the cam 39 slides onto the upper end of the shaft of the actuating rod 27 supported in the hollow support portion 2Ib, and the actuating rod 27 is pushed downward against the elastic force of the compression spring 29. Press down. As a result, the lower end of the shaft of the actuating rod 27 comes into contact with the upper end of the actuating shaft 17a of the actuating body 17, and the actuating body 17
is pressed down, and the bottle switch 13 is turned on by contact between the movable electrode of the actuating body 17 and the fixed electrode attached to the switch case 15. Further, as the actuating body 17 remains stationary, the pressing shaft 17b is moved to the other arm portion 49d of the actuating lever 49.
Press down. As a result, the operating lever 49 rotates clockwise as shown in FIG. 2 around the protrusion 49a,
The pad receiver 43 is moved upward against the elastic force of the compression spring 45. As a result, the brake pad 47 separates from the rotor 9d, and the electric motor 9 enters the non-braking state. When the main power switch is turned on in the above state, the electric motor 9
is driven, the cutter 23 connected to the rotating shaft 9a and the connecting shaft 31 is rotated in a desired direction, and the food placed in the container body 21 is cooked.

In FIG. 4 showing the braking action of the braking mechanism 11, while the cutter 23 is rotating due to the above action, the lid 25 that closes the upper opening 22 of the container body 21 moves counterclockwise along the upper opening edge of the container body 21. When rotated in the direction, the engaging portion 21
c is disengaged from the engaged portion 37, the upper end of the shaft of the actuating rod 27 and the cam 39 are released from contact, and the elastic force of the compression spring 29 causes the actuating rod 27 to move upward.

As a result, the movable electrode and the fixed electrode of the bottle switch 13 are separated from each other to turn off the bottle switch 13, thereby interrupting the supply of driving power to the electric motor 9. In addition, the bottle switch 13 is OFF.
Even after the F operation, the electric motor 9 continues to rotate due to its inertia force. Further, since the actuating body 17 that contacts the lower end of the shaft of the actuating rod 27 moves upward due to the elastic force of the compression spring 18, the actuating lever 49 is centered around the protrusion 49a due to the elastic force of the compression spring 45, as shown in FIG. Rotate counterclockwise to move the pad receiver 43 downward. As a result, the brake pad 47 comes into pressure contact with the rotor 9d with a pressure corresponding to the elastic force of the compression spring 45, thereby braking the rotation of the rotor 9d. As a result, the cutter 23, which has continued to rotate due to inertia, is braked and stopped.

In this way, in this embodiment, when removing the lid 25 from the upper end opening of the container body 21, the operating lever 49 is rotated by the operating rod 27, which moves upward in conjunction with the removal operation of the lid 25.
A brake pad 47 is attached to the rotor 9d, which continues to rotate due to inertia.
The cutter 23 can be braked and stopped by pressing the cutter 23 into contact with the cutter 23.

In the above explanation, the brake pad 47 is brought into pressure contact with the rotor 9d by the operating lever 49 that rotates in conjunction with the removal operation of the cover 25, but the brake plate is fixed to the rotating shaft 9a located outside the motor cover. The rotation of the cutter 23, which continues to rotate due to inertial force, is braked and stopped by pressing the brake pad 47 against the brake plate by an operating lever 49 that rotates in conjunction with the removal operation of the lid 25. Good too.

[Effects of the Invention] Therefore, the present invention provides an electric cooking device that can ensure the safety of the operator by stopping the rotating member that continues to rotate due to inertia force in a short time when removing the lid from the container body. is possible.
