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 configuration and problems Generally, this type of cooking machine combines a juicer cooking device body 2 with an 11-tass moving part main body 1 as shown in FIG. 1, or mixer cooking as shown in FIG. 2. The container 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 6 of the mixer cooker body 3 must be kept at a high speed of 1200 rpm. Two rotational outputs must be produced.

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 coupled 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 low-speed rotation connector 9 includes a pulley 1 rotatably supported by an oil-less metal 10 fitted to the rotating shaft 7.
It is connected to 1. A belt 12 is attached to the pulley 11 from the rotating shaft 7. Reduction pulley 13. The rotation is transmitted through the belt 14 at a reduced speed. The bearing 16 above the rotating shaft 7 is a ball bearing that can withstand the thrust load when the juicer cooker body 2 is used, that is, when material is pushed in from above.

In the conventional cooking machine with the above configuration, when liquid such as water or juice flows into the connector 9 for low speed rotation,
There is a problem in that the liquid enters between the rotating shaft 7 and the oil-less metal 10, causing the oil-less metal 1o 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 liquid distributed in the juicer cooking device body 2 to rotate at high speed, resulting in a very dangerous situation. becomes. In addition, when using the juicer cooking device body 2, the thrust force generated when pushing the material from above is applied directly to the bearing 16 of the motor 6, which often causes ball bearing trouble due to unbalanced load and causes abnormal noise. was. Furthermore, the heat of the motor 6 is transmitted from the rotating shaft 7 to the oilless metal 1o, causing a problem of seizure due to lack of oil in the oilless metal.

Purpose of the Invention The present invention takes into consideration the above-mentioned conventional problems, and aims to provide a cooking machine that can be used safely by preventing the low-speed rotation connector from rotating at high speed due to trouble. be.

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
The structure includes a hollow shaft that is fitted to the rotating shaft with a small gap and fixed to a fixed member, a bearing member provided on the outer periphery of the hollow shaft, and a connector that is rotationally held by the bearing member. The outer connector member can be rotated separately from the inner rotating shaft, which rotates at high speed.

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

In the figure, reference numeral 16 denotes a motor, which has a rotating shaft 17 and is pivotally supported in a frame 18 by obi-shaped bearings 19 and 20. A bracket 22 through which the rotating shaft 17 passes is fixed to the upper part of the frame 18, and a hollow shaft 23 that fits with the rotating shaft 17 with a small gap is fixed on the bracket 22. A connector 24 for high-speed rotation is connected to the upper end of the rotating shaft 17, and an oil-less metal 26, which is a bearing member, is fitted on the outside of the hollow shaft 23.
A connector 27 for low speed rotation is connected to a pulley 26 fitted on the outside of the rotor 6.

The pulley 26 is connected to a belt 29° and a reduction pulley 30. It is designed to transmit rotation at a lower speed than the belt 31. And the bottom of the oilless metal 25 is washer 3
2, so that it can be received by the bracket 22. Note that the juicer cooking device body and the mixer cooking device body are the same as those described above, so a description of their configuration will be omitted. The cooking machine with the above configuration has an oil-less metal 25 to which a 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. Therefore, even if liquid etc. enter, the oil-less metal 25 and the rotating shaft 17 will not rust. Therefore, the connector 27 for low-speed rotation does not rotate at high speed, and safety is ensured. In addition, the thrust load generated when the juicer cooker body is used is received by the bracket 22, and a large force is not applied to the bearing 19 etc., so this bearing 1
9 can be changed to an oil-free metal, and there is no problem with ball bearings or noise caused by uneven loading. Furthermore, the rotating shaft 17 has a small gap with respect to the hollow shaft 23, and the heat of the motor 16 is transferred to the oil-less metal 26 on the outer periphery of the hollow shaft 23.
Therefore, there is no seizure due to lack of oil in the oil-less metal 26.

In addition, although a belt and a pulley are used as a speed reduction means in the above embodiment, a speed reduction means using gears may also be used.

Effects of the Invention As is clear from the description of the embodiments above, the cooking machine of the present invention is equipped with a connector for high-speed rotation and a connector for low-speed rotation, and these are driven by a two-axis concentric mechanism. Since the rotating members on the low-speed side are completely separated by the hollow shaft, even if the low-speed side bearing becomes stuck due to trouble, the low-speed side will never rotate at high speed.
It is safe and useful, for example, when the mixer cooker body and juicer cooker body are used interchangeably.
