Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electric cooking device for cooking food by slicing or kneading it with a rotating member such as a rotating cutter blade or a stirring member.

[Prior art]

The conventional electric cooking device disclosed in JP-A-60-14832 has a bearing member centered around a hollow shaft that is fitted with a small gap to the rotating shaft of a motor built into the main body of the drive unit. a connector for high-speed rotation coupled to the rotating shaft, a connector for low-speed rotation coupled to the rotating shaft via a transmission means, and a connector for high-speed rotation or low-speed rotation depending on the cooking purpose. It is composed of at least two types of cooking device bodies that are selectively connected. For example, in the case of a cooking device such as a juicer that rotates the cutter at a relatively low speed for cooking, the rotating shaft of the cutter can be connected to the connector for low-speed rotation by attaching the cooking device to the drive unit main body. For example, in the case of a cooking device such as a mixer that rotates a cutter at a relatively high speed for cooking, the rotating shaft of the cutter can be connected to a connector for high-speed rotation by attaching the cooking device to the drive main body. are doing.

There is. Further, a pressing portion 7c is provided at the lower end of the bottle cover 7.
is formed, and when the bottle cover 7 is attached to the drive unit main body 3, the actuating rod 3 is pressed by the pressing portion 7c so that the locking groove 7b locks with the engaging protrusion 41a.
Press down on 3 to turn on bottle switch 39.

Next, the operation of the electric cooking device 1 configured as described above will be explained with reference to FIGS. 2 to 5.

To explain the effect of rotating the cutter blade 53 at high speed when the electric cooking device 1 is used as a mixer, for example, in FIGS. wall 5b
are fitted so that the first engagement piece 43b and the first locking groove 5c correspond to each other. At this time, since the bottle part 5 is attached to the drive part main body 3 in a state located above, the high speed gear 29 is connected to the internal teeth 47b in the recess 47a. In the above state, the bottle cover 7 is attached to the first support step 41 of the drive unit main body 3.
covers the upper end opening of the bottle part 5 and the entire outer peripheral surface of the bottle part 5, and also covers the locking groove 7b and the engaging protrusion 41a.
When the bottle cover 7 is attached in a corresponding manner, the pressing portion 7c of the bottle cover 7 comes into contact with the actuating rod 33 and pushes the actuating rod 33 downward against the elastic force of the compression spring 37. As a result, the pressing piece 35 comes into contact with the bottle switch 39, and the bottle switch 39 is activated.
Turn ON. As a result, the electric motor 11 is driven to rotate, the connecting gear 47 connected to the high-speed gear 29 rotates at high speed according to the rotation speed of the electric motor 11, and as the cutter blade 53 rotates at high speed, the bottle portion 5
Food placed inside is cooked.

Next, to explain the effect of rotating the cutter blade 53 at low speed when the electric cooking device 1 is used as a juicer, for example, FIG. In FIG. 5, which shows the connected state of the low-speed gear 27, the hanging wall 5b of the bottle part 5 is connected to the outer circumferential surface of the second support step 43, and the first engagement piece 43b and the second locking The grooves 5d, the second engaging pieces 43c and the first locking grooves 5c, and the rib locking grooves 5e and the ribs 43d are fitted so as to correspond to each other. At this time, the first engagement piece 43b and the second engagement piece 43c are formed with an interval in the vertical direction corresponding to the height difference between the low-speed gear 27 and the low-speed gear 29. As shown in FIG. 5, the connecting gear 47 is located lower than in the connected state during high speed rotation (see FIG. 2). For this reason,
The low speed gear 2 is connected to the internal teeth 47b of the connecting gear 47.
7 are connected. At this time, the high-speed gear 29 is located within the recess 47a and is disconnected from the internal teeth 47b. When the bottle cover 7 is attached to the drive section main body 3 in the above state, the electric motor 11 is rotationally driven in the same way as the operation described above. At this time, the driving force of the electric motor 11 is transmitted to the connecting gear 47 via the gear 11b, the planetary gear 19, the internal teeth 21a, the hollow shaft 23, and the low-speed gear 27. Therefore, the connecting gear 47 rotates at a speed with a reduction ratio corresponding to the difference in the number of teeth between the internal teeth 21a and the planetary gear 19 with respect to the speed of the electric motor 11, and rotates the cutter blade 53 at a low speed. As a result, the food placed in the bottle portion 5 is cooked by the cutter blade 53 rotating at a low speed.

In this way, this embodiment uses a single bottle part 5, and by changing the mounting position of the bottle part 5 with respect to the drive part main body 3 in the vertical direction, the connecting gear 47
It is possible to cook by selectively connecting the cutter blade 53 to the low-speed gear 27 or the high-speed gear 29 to rotate the cutter blade 53 at a low speed or a high speed depending on the respective cooking purpose.

〔Effect of the invention〕

For this reason, the present invention uses a single bottle part,
It is possible to provide an electric cooking device in which the rotation speed of the rotating member can be changed by changing the mounting position of the bottle part with respect to the drive part main body.
