Description

[Detailed explanation of the invention] [Industrial application field] This invention is a small electric cooking device that grates or cuts (slices) cooking ingredients in a hand-held state. It relates to a switch structure that maintains the ON state of the switch and the OFF state of the power switch when not cooking.

[Conventional technology]

In Utility Model Application No. 63-160180, the present applicant proposed a small electric cooking device that allows the power switch to be turned on only when a lid covering the cutter disc of a small electric cooking device for cooking ingredients in a hand-held state is attached. We proposed a switch structure for cooking equipment. That is, the elastic member is always moved by the elastic force of the elastic member and comes into contact with the switch button, regulating the ON operation of the switch button, and the contact between the switch button and the switch button due to the contact with the operating piece provided on the lid body. The structure includes a regulating member that allows the switch button to be turned on by slipping out from the switch button.

[The problem that the idea attempts to solve]

However, with the above-described switch structure, the switch button must be held in the power ON position during cooking. In other words, when cooking ingredients while holding up the small electric cooking device, the operator must hold the grip of the drive unit with one hand and hold the switch button in the power ON position while holding the switch button in the power ON position with the other hand. The cooking ingredients are put in by hand through the input opening, and the cooking ingredients are pressed against the blade disk while cooking. For this reason, when pressing the cooking ingredients against the cutter disk, it is difficult to hold the switch button in the power ON position with the hand holding the drive unit body, resulting in the problem that the power switch turns OFF during the cooking process. . In addition, during cooking, it is necessary to firmly grasp the main body of the drive unit with one hand against the pressing force of the cooking ingredients against the blade disk, and to maintain the state in which the switch button is moved. It was my fault.

This invention was devised to solve the above-mentioned conventional drawbacks, and its purpose is to ensure that the power is turned on and off in a small electric cooking device that cooks ingredients while handheld. To provide a switch structure that allows cooking materials to be easily cooked while being held in one hand.

[Means for solving problems]

For this reason, the present invention provides a small electric cooking device that cooks input cooking ingredients to a desired state using a blade disc that rotates while gripping a main body of a drive unit in which an electric motor is built-in. a power switch, a slide member that is movably supported by the case of the drive unit main body and turns on the power switch as the slide member moves, and a first slide member that is provided according to a power ON position and a power OFF position. and a second engaged portion, and an elastic member that selectively engages the engaging portion with the first and second engaged portions and maintains the engaged state by elastic force. It is characterized by forming a structure.

[Effect of invention]

Since the present invention is configured as described above, when the power switch is in the OFF state, the engaging part biased by the elastic member engages with the second engaged part, and the engaged state is maintained. is retained. On the other hand, when the slide member is moved when the electric motor is driven to rotate the blade disk, the power switch is turned on by the slide member. At this time, the engaging part that was engaged with the second engaged part resists the elastic force of the elastic member and is released from the engaged state, and then the engaging part that has moved to the power ON position becomes the first engaged part. is engaged with the engaged portion of. The engaging portion is biased by the elastic member and maintained in the engaged state with the first engaged portion. Therefore, even if the operation to move the slide member is released, the power switch remains in the ON state, so that the cooking ingredients can be cooked while firmly holding the drive unit main body with one hand.

Next, the operation of the small electric cooking device 1 configured as described above will be explained with reference to FIGS. 6 to 8.

6 to 8 are explanatory diagrams showing the moving state of the slide plate. First, the state in which the lid body 21 is not attached to the main body case 3, that is, the state in which the blade disc 1 is
7 is exposed, the regulating plate 37 is connected to the wire spring 39
It is biased by the elastic force of , and is located in front of the shaft portion 41c. Therefore, switch button 45 turns on the power.
When the slide plate 41 is operated to move in the direction, the movement of the slide plate 41 is regulated by the abutment of the shaft portion 41c against the regulation plate 37. Also, switch button 45
In the OFF state, the engaging portion 41a is in the first recessed portion 31f.
, and the slide plate 41 is held in the power OFF position. As a result, when the lid body 21 is not attached to the main body case 3, the power switch 27 is maintained in the OFF state.

Next, to explain the cooking operation, the dish member 15 is attached to the upper surface of the attachment part 3b of the main body case 3, and the cutter disk 17 is attached to the drive shaft 9 passing through the through hole 15a. On the other hand, when the lid 21 is attached by rotating the lid 21, the operating piece 23 of the lid 21 enters into the introduction opening 25. At this time, the actuating piece 23 rotates the regulating plate 37 that comes into contact with it against the elastic force of the wire spring 39.
The shaft portion 41c is separated from the front. This makes the slide plate 41 movable.

In order to rotationally drive the cutter disk 17 in order to grate the cooking material inputted from the input cylindrical portion 21f, when the switch button 45 is moved to the power ON position in the above state, the slide plate 41 is moved. After the engaging portion 41a is disengaged from the first recess 31f and moved due to the elastic deformation of the rib 41f, when the engaging portion 41a is located in the second recess 31g, the above-mentioned elastic return is performed. The engaging portion 41a is engaged with the second recess 31g by the rib 41f.
As a result, the slide plate 4 in the power ON position
A moving state of 1 is maintained. Therefore, even if the moving operation of the switch button 45 is released, the moving state of the slide plate 41 at the power ON position is maintained. Furthermore, the shaft portion 41c enters the recess 23a of the actuating piece 23, allowing the slide plate 41 to move, and the actuating protrusion 41d presses the actuating rod 27a to turn on the power switch 27. As a result, the cutter disk 17 is rotated by the rotationally driven electric motor 5, and the cooking material that comes into contact with the cutter disk 17 is grated.

The grated cooking material passes through the gap between the support rib 17a and the wall surface of the lid 21 and the dish member 15 and is moved onto the dish member 15, and then is removed by the scraping plate 17d into the discharge notch 15c. is discharged to the outside through the
