Description

[Detailed description of the device]

[Industrial application] This invention is a small electric cooking device that can grate cooking material, slice it to the required thickness, or chop it, and in particular, has a handheld size. However, the present invention relates to a small electric cooking device including two types of blade members that can be rotated at different rotation speeds depending on a cooking state.

[Prior art]

The applicant of the present invention, for example, as shown in Japanese Utility Model Application Laid-Open No. 2-82245, covers a main body portion integrally provided with a grip portion having a grippable size and a drive portion to which a drive shaft is attached, and an upper surface of the drive portion, A dish member having a discharge opening at the tip, a blade member removably attached to a drive shaft that passes through the dish member, and a drive unit or a dish member attached to cover the blade member,
We proposed a small electric cooking device consisting of a lid with a charging part for charging cooking ingredients.

[Problems to be solved by the device]

Generally, when slicing the cooking material to a required thickness or when grazing, the blade member is rotated at a relatively low speed, while when the cooking material is chopped, the blade member is rotated at a relatively high speed. There is a need. However, in the above-mentioned handheld small-sized electric cooking device, a control circuit for switching the rotation speed of the electric motor between low speed rotation and high speed rotation or a switching means for switching the gear train from the electric motor to the drive shaft to low speed rotation or high speed rotation. It was difficult to secure a space for incorporating the. Therefore, in the hand-held electric cooking device, the rotation speed or the gear train of the electric motor is set in advance so that the rotation speed of the blade member becomes low speed rotation or high speed rotation. I had to prepare multiple small electric cooking devices. Further, a cooking device has been proposed which can switch between high-speed rotation and low-speed rotation, such as Japanese Utility Model No. 55-74532. However, in this cooking device, a shaft for high-speed rotation and a shaft for constant-speed rotation are simultaneously provided. Since the structure is provided, the container (container) and the blade must be replaced each time to cook in each cooking state, resulting in poor work efficiency. The present invention was devised in order to solve the above-mentioned conventional drawbacks, and its purpose is to provide two kinds of blade members with different predetermined rotation speeds according to their respective cooking conditions in a small space. It is to provide a small-sized electric cooking device that can be rotated and cooked at. Another object of the present invention is to provide a small-sized electric cooking apparatus that can perform cooking operations individually and can improve the efficiency of cooking operations.

Gear 55
The intermediate gear 57 meshed with b is connected to the first gear train 15 to rotate the first drive shaft 9 at a low speed. At this time, the small diameter gear
Since the mesh between the intermediate gear 57 meshed with 55b and the second gear train 17 is released, the rotation of the second drive shaft 11 is prohibited. On the contrary, when the second blade member 31 is rotated at a high speed to cook the cooking material, as shown in FIG. 7, the bearing portion 61 is moved to the lower position and the intermediate gear 5 meshed with the small diameter gear 55b.
By engaging 7 with the second gear train 17, the second drive shaft 11 is rotated at high speed. At this time, since the meshing between the intermediate gear 57 meshing with the small diameter gear 55b and the first gear train 15 is released, the rotation of the first drive shaft 9 is prohibited. As described above, in the second aspect, the first drive shaft 9 or the second drive shaft 9
Drive shaft 11 can be selectively rotated. For example, the first drive shaft 9 is provided with the first blade member 23, and the second drive shaft is provided.
When the second blade member 31 is attached to 11 and cooking is performed by one of the blade members, the rotation of the other blade member is prohibited, so that the safety of the cooking operation can be ensured. In the above description, the inclined groove 11 that is inclined from the lower side to the upper side along the rotation direction is formed on the inner peripheral surface of the shaft support hole 11a of the second drive shaft 11.
The protrusion 33a provided on the shaft 33 of the second blade member 31 is slidably contacted with the inclined groove 11b by the rotating second drive shaft 11 and is fixed by lifting it upward and fixing it to prevent rotation and slippage. However, as shown in FIG. 8, at least two split grooves 81b extending in the axial direction are formed in the second drive shaft 81 corresponding to the shaft support hole 81a formed in the lower end. An elastically deformable stop ring 83 is inserted into the outer periphery of the second drive shaft 81 corresponding to the split groove 81b, and the protrusion 33b is engaged with the split groove 81b to cause the second drive shaft 81 to move in the second direction. The tool member 31 is prevented from rotating, and the second drive shaft 81 is prevented from coming off from the second drive shaft 81 by the engagement between the stop ring 83 and the protrusion 33b that has been overcome by the elastic deformation of the stop ring 83. It may be.
