2. Description of the Related Art The applicant of the present invention has disclosed a main body case having a holding portion on one side, a driving portion rotatably supported on a rotating shaft connected to a built-in electric motor, and an upper surface of the driving portion. It comprises a dish member to be covered, a blade disk that is exchangeably attached to the rotating shaft, and that cuts the cooking material into a desired state such as sliced, and a lid that is attached to the drive unit or the dish member so as to cover the blade disk. , Grate cooking ingredients while holding the body case with one hand,
A small electric cooking device that can be chopped or sliced was proposed.

[0003]

In this type of small-sized electric cooking device, in order to prevent an operator from being injured by a rotating blade disk, a lid is attached so as to cover the blade disk. Only requires a safety switch to rotate the blade disk.

The above-mentioned safety switch generally has a structure in which a limit switch or the like is mounted outside the power switch, and when the safety switch is first turned on by mounting the lid, the power switch can be turned on. is there.

However, in the case of a small electric cooking device, it is difficult to secure a space for mounting a safety switch outside the power switch because the device itself is small.

The present invention has been devised in order to solve the above-mentioned conventional drawbacks, and has as its object the object of the present invention when a lid is mounted without providing a safety switch outside a power switch. Only an object of the present invention is to provide a safety switch mechanism of a small electric cooking device that enables ON operation of a power switch to ensure worker safety.

SUMMARY OF THE INVENTION For this reason, the present invention provides a main body case having a driving part in which a rotating shaft connected to an electric motor on one side and an electric motor is rotatably supported on the other, A dish member attached to cover the upper surface of the driving unit by inserting the rotating shaft, and a knife disk detachably attached to the rotating shaft inserted through the dish member and having a knife for cooking the cooking material in a desired state; A small electric cooking device comprising: a drive unit or a lid member which is detachably attached to the dish member so as to cover the blade disk, and which has a charging portion for charging the blade with the cooking material. A switch button operably supported and provided with an operating rod having a large-diameter portion and a small-diameter portion from the upper part to the lower part at the lower part of the shaft, and is disposed relative to the lower end of the operating rod at a required interval. Switch member The switch button is normally positioned between the lower end of the operating rod and the switch member so as to maintain a required distance between the first elastic member that maintains the OFF state and the switch member. A long hole movably supported, having at one end an engaged portion engageable with an operating piece provided on the lid body, and having at the other end a substantially coincident with a small diameter portion of the operating rod and capable of being inserted therethrough; An operating plate having a through hole that is continuous with the long hole and that can be inserted in conformity with the large diameter portion of the operating rod, and the operating plate is attached so that the small diameter portion of the operating rod is always located in the long hole. And a second elastic member for biasing. When the lid is not attached to the driving unit or the dish member so as to cover the blade disk, the small diameter portion of the operating rod is inserted into the long groove of the operating plate urged by the second elastic member. Since the push-down of the operating rod is regulated by the large-diameter portion, the ON operation of the switch member is regulated even when the switch button is pushed down. On the other hand, when the lid is attached to the drive unit or the plate member, the operating plate is rotated against the elastic force of the first elastic member with the engagement of the lid with the operating piece. The large diameter portion of the operating rod is opposed to the through hole. For this reason, when the switch button is pressed down, the large-diameter portion is inserted into the through-hole, and the operating rod can be pressed down to turn on the switch member.
Activate.

Is inserted into the long hole 47a.

The other end of a wire spring 49 constituting a second elastic member whose one end is locked to the inner surface of the main body case 3 is locked to the operating plate 43, and the operating plate 43 is clocked by the elastic force of the wire spring 49. It is urged to rotate in the direction.

A power switch 51 is attached to the main body case 3 below the operating rod 39. When the power switch 51 is turned on, the electric motor 5 is driven to rotate.

Next, the operation of the small electric cooking device 1 will be described with reference to FIGS.
This will be described with reference to FIG.

FIG. 4 is a schematic perspective view showing the rotating state of the operation plate, and FIG. 5 is a schematic perspective view showing the pressed state of the switch button.

When the cover 23 is not mounted on the drive section 9, the operating plate 43 is urged to rotate clockwise (in the direction of the solid arrow A) shown in FIG. The small diameter portion 39 b of the rod 39 is inserted into the long hole 47 a of the operation plate 43.

In this state, when the switch button 37 is pressed down, as shown in FIG.
9a is in contact with the other end of the operation plate 43 corresponding to the periphery of the long hole 47a, and the movement in the axial direction downward is restricted. For this reason,
The power switch 51 is kept in the OFF state.

After the plate member 13 is mounted on the upper surface of the drive unit 9 and the blade disk 17 is mounted on the rotating shaft 11 passing through the through hole 13a, the lid 23 is engaged with the engagement groove 35a of the engagement piece 35 and the drive unit 9 When the lid 23 is rotated and attached to the drive unit 9 so that the engaging portion of the
Of the operating plate 43 enters the opening 42 and comes into contact with one end of the operating plate 43.

The operating plate 43 against which the operating piece 33 comes into contact is rotated counterclockwise (in the direction of the solid arrow B) shown in FIG. 33 are engaged.

With the rotation of the operating plate 43, the large-diameter portion 39a of the operating rod 39 is positioned in the large-diameter hole 47b at the other end of the operating plate 43.

When the switch button 37 is pressed in the above state, as shown in FIG. 5, the operating rod 39 moves downward along the axis (in the direction of the solid arrow C) with the insertion of the large-diameter portion 39a into the large-diameter hole 47b. Then, the lower end of the shaft contacts the power switch 51 to be turned ON.

Thus, the electric motor 5 is driven to rotate the blade disk 17 in a predetermined direction. At this time, the rotation of the operating plate 43 is restricted by the insertion of the large-diameter portion 39a of the operating rod 39 into the large-diameter hole 47b, and the blade disc 1 is
When the cover 7 rotates, the cover 23 is prevented from coming off.

When the cooking material is put on the rotating blade disk 17 through the charging cylinder 31 in the above state, the cooking material is cooked to a desired state by the rotating blade disk 17 and then discharged. It is discharged to the outside via the part 29.
