Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cooking machine, such as a juicer and a mixer, which is constructed by arbitrarily combining two cooking devices having different rotational speeds in a drive main body.

Conventional Structures and Problems Generally, this type of cooking machine consists of a combination of a drive part main body 1 and a Jouvoo cooking device body 2, as shown in FIG. 1, or a mixer cooking device, as shown in FIG. The bodies 3 are combined, that is, the drive unit main body 1 is shared.

By the way, the cutter 4 in the juicer cooking device body 2
must be rotated at a low speed of 4600 rpm, while the rotation of the cutter 5 of the mixer cooker body 3 must be rotated at a high speed of 1200 rpm. must produce two rotational outputs.

For this reason, the rotation output mechanism in the drive section main body 1 was constructed as shown in FIG. 3. That is, a connector 8 for high-speed rotation is directly connected to the upper end of the rotating shaft 7 of the motor 6, and a connector 9 for low-speed rotation is provided concentrically above the rotating shaft 7. The connector 9 for low speed rotation is coupled to a pulley 11 that is rotatably supported by an oilless metal 10 that is a bearing member fitted to the rotating shaft 7. The pulley 11 has a rotary shaft 7 and a shiveleaf'.

Belt 12. Reduction pulley 13. The rotation is transmitted through the belt 14 at a reduced speed. The bearing 15 above the rotating shaft 7 is a pole bearing that can withstand the thrust load when the juicer cooker body 2 is used, that is, when pushing the material upward.

In the conventional cooking machine with the above configuration, when liquid such as water or liquid gets into the connector 9 for low speed rotation,
There is a problem that the liquid enters between the rotating shaft 7 and the oil-less metal 10, causing the oil-less metal 1Q to rust on the rotating shaft 7. When the rust occurs, the belt 12 or 14 comes off, and the low-speed rotation connector 9 rotates at high speed together with the rotating shaft 7, causing the separation capacity of the juicer cooker body 2 to rotate at high speed, resulting in a very dangerous situation. becomes. When using the juicer cooker body 2, the thrust force generated when pushing the material from above is applied directly to the bearing 15 of the motor 6, causing many problems with the ball bearing ring due to uneven load, and causing abnormal noise. It became. Furthermore, motor 6
The heat is transmitted through the rotating shaft 7 to the oil-less metal 10, and there is a problem of seizure due to lack of oil in the oil-less metal.

Purpose of the Invention The present invention takes into account the above-mentioned conventional problems, and provides a connector for low-speed rotation that does not rotate at high speed due to trouble, and also provides a low-noise and low-noise connector that does not apply large thrust force to the bearing. The purpose is to provide a cooking machine that can be used safely.

Structure of the Invention In order to achieve the above-mentioned object, the present invention replaces two different cooker bodies with a drive unit main body, and uses a two-axis concentric rotating shaft member provided in the drive unit main body to cut the two cooker bodies. A cooking machine that rotates rotating parts such as
A hollow shaft fitted with this rotating shaft with a small gap,
The outer rotating member provided on the outer periphery of the hollow shaft is configured with multiple connectors, and independent connectors are connected to the inner rotating shaft and the outer rotating member, respectively, and the outer rotating member reduces the rotation of the inner rotating shaft. A deceleration mechanism for transmitting the transmission is provided, the hollow shaft is fixed, and the placket is configured to support the lower part of the outer rotating member, the placket has an opening in a part, and is fixed to the motor frame. It is something.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 4 and 6.

In the figure, 16 is a motor and an inner rotating member.
The motor has a rotating shaft 17, and the rotating shaft 17 is pivotally supported in a motor frame 18 by core-shaped bearings 19 and 20. A placket 22 through which the rotating shaft 17 passes is fixed to the upper part of the frame 18. This placket 22 is formed approximately in the shape of a cap, and has an opening 22' on one side opposite to the input port A of the juicer cooker body with respect to the center of rotation. On this bracket 22 is fixed a hollow shaft 23 that fits into the rotating shaft 17 with a small gap. At the upper end of the rotating shaft 1 is a connector 24 for high-speed rotation.
An outer rotating member is rotatably provided on the outside of the hollow shaft 23. This outer rotating member is a hollow shaft 23
A connector 27 for low-speed rotation is connected to the pulley 26, which is fitted to the outside of the oil-less metal 25 and functions as a bearing. The pulley 26 has a pulley 28 attached to the lower part of the placket 22 of the rotating shaft 17, and a seatbelt 29. Reduction pulley 30° belt 31
It is designed to transmit low speed rotation. The lower part of the oil-less metal 25 can be received by the placket 22 via the Wano 7 ear 32. Note that the simmering cooker body and the mixer cooker body are the same as those described above, so a description of their construction will be omitted.

In the cooking machine with the above configuration, the oil-less metal 26 to which the connector 27 for low-speed rotation is connected is fitted into the hollow shaft 23, that is, it is concentric with the rotating shaft 17 that rotates at high speed, but is separate from it. Even if the oil-less metal 25 and the rotating shaft 17 get intruded, the oil-less metal 25 and the rotating shaft 17 will not rust, and the connector 27 for low-speed rotation will not rotate at high speed, so safety is ensured. In addition, the thrust load generated when the juicer cooker body is used is received by the placket 22, and no large force is applied to the bearing 19, etc., so the bearing 19f! It can be changed to non-oil-less metal, and there is no problem with ball bearings or noise caused by uneven loading. Furthermore, the rotary shaft 17 has a gap of /J% with respect to the hollow shaft 23, so that the heat of the motor 16 is not transmitted to the oil-less metal 26 on the outer periphery of the hollow shaft 23.
There is no burning due to lack of oil. In addition, placket 2
2 has an opening 22' in a part thereof, and when the juicer cooker body is in operation, it acts as an anti-photograph against low-speed rotational vibrations and prevents abnormal vibrations.

In addition, although a belt and a pulley are used as the speed reduction means in the Toi example, a speed reduction means using gears may also be used. Effects of the invention As is clear from the description of the above example, the cooker of the present invention can rotate at high speed. A connector for high-speed rotation and a connector for low-speed rotation are provided, and these are driven by a two-axis concentric mechanism.The high-speed side and low-speed side rotating members are completely separated by a hollow shaft, so there is no problem in low-speed rotation. Even if the rotating member on the side becomes stuck, the low speed side will never rotate at high speed, making it safe. Further, the placket that fixes the hollow shaft receives the thrust load of the rotating member on the low-speed side, thereby preventing load movement from being applied to the bearing, and the opening has the effect of preventing abnormal vibrations during low-speed rotation.
