DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the first means of the present invention will be described below with reference to FIG. Reference numeral 10 denotes a driving motor, and the motor bracket on the rotary shaft 12 side is a stand 24 of the cup stand 13.
Has become. The stand 24 is sandwiched by an elastic body 14 made of a cylindrical rubber material, and the outer peripheral portion of the elastic body 14 is sandwiched by a main body 15. In this way, the motor 10 is supported by the main body 15 in a vibration-proof manner.
A connector A16 is fixed to the upper end of the rotary shaft 12 of the motor 10. Reference numeral 17 denotes a cutter that crushes and cuts the cooking material by rotating at high speed, and is fixed to the upper end of the cutter shaft 18. The cutter shaft 18 is held by a bearing 11 provided on an upper plate portion 19 located at the center of the cup base 13. At the lower end of the cutter shaft 18, the connector B2
1 is fixed. In this way, the cup base 13 is attached to the main body 1
When mounted on the connector 5, the connector A16 and the connector B21 mesh with each other to connect the motor 10 and the cutter shaft 18. A cup 20 is screwed onto the upper portion of the cup base 13.
That is, the screw portion 2 provided inside the upper side wall of the cup base 13
2 and the screw portion provided on the outer periphery of the lower side of the cup 20 are screwed together, so that the cup 20 can be detachably attached to the cup base 13. The space between the cup 20 and the cup base 13 and the space between the cutter shaft 18 and the bearing 11 are sealed with a rubber-like sealing material (not shown). Therefore, even if a liquid material is put in the cup 20, it will not leak. 25
Is a cup lid, which has a cylindrical shape and is fixed by being fitted on the upper portion of the main body 15. Reference numeral 26 is an inner lid made of a cylindrical rubber plate attached to the cup lid 25, and closely adheres to the inner circumference of the cup 20 to serve as a seal for preventing the cooking material from splashing. The inner lid 26 has an air vent hole 27 near the center. The air vent hole 27 has a function of preventing an abnormal increase in pressure inside the cup 20 when the cooking material is cut and stirred. In this way, the cup stand 13 with the cup 20 attached is placed on the stand 24.
When the cup lid 25 is fitted and attached to the main body 15, a gap is maintained between the cup lid 25 and the cup 20 both in the upward direction and the circumferential direction.

Next, the operation of the structure of this embodiment will be described. A cup 20 containing cooking ingredients such as fruits, milk, ice, water, etc. is screwed onto a cup stand 13 and placed on a cup stand 24, and a cup lid 25 is fitted into a groove at the upper end of the main body 15 and attached. At this time, the connector A16 and the connector B2
1, and the cutter 17 rotates at high speed when the motor 10 is driven. In this way, the cooking material in the cup 20 is cut and ground. At this time, a very loud noise is generated in the cup 20, but the noise is not transmitted to the outside due to the sound insulation effect of the cup lid 25. Further, the cup 20 itself also causes a large vibration due to the violent collision of the cooking material, which is a noise source. However, in the present embodiment, as described above, since the cup 20 itself is surrounded by the cup lid 25 and the main body 15 and is sound-insulated, the noise generated from the cup 20 is not transmitted to the outside. Further, since the inner lid 26 is extremely flexible, the vibration is hardly transmitted to the cup lid 25 or the like by transmitting the inner lid 26. The noise of the motor 10 is also shielded by the cup lid 25 and the main body 15, and the vibration is hardly transmitted to the main body 15 and the cup lid 25 because the vibration is supported by the elastic body 14.

As described above, according to this embodiment, the noise generated from the electric cooking machine is insulated and the vibration is isolated.
Noise is greatly reduced. Further, since the cup table 13 is directly mounted on the table 24 which also serves as a motor bracket, the connector A12 and the connector B21 are fitted with high accuracy, and abnormal vibration does not occur. Further, the noise transmitted from the air vent hole 27 is not directly propagated to the outside because it is surrounded by the cup 20 and the main body 15. Further, in this embodiment, since the area of the air vent hole 27 can be set to be relatively large, pressure pulsation inside the cup 20 is reduced, which leads to noise reduction. In addition, the inner lid 26 is attached to the cup lid 25, and basically the number of parts of the configuration of this embodiment is the same as that of the conventional configuration. Therefore, the work such as preparation and rearrangement is not more troublesome than in the past.

The inner lid 26 may be a cylindrical seal attached to the upper surface of the cup 20 as shown in FIG.

Next, an embodiment of the second means of the present invention will be described with reference to FIG. The same parts as in the above embodiment include
The same numbers are attached and the description is omitted.

Reference numeral 30 denotes a cylindrical cup which is detachably screwed to the cup base 13 and has an outwardly bent back portion 33 at the upper end. 31 is a sound insulation case,
It is inserted with a gap in the outer periphery of the cup 30, and is fitted and fixed to the main body 34. 32 is a cup lid, to which a disc-shaped inner lid 35 made of a thin rubber plate is fixed. The inner lid 35 has a small hole 36 for venting air near the center,
The pressure inside the cup 30 is prevented from rising abnormally when the cooking material is cut and stirred. This cup lid 32
Are fitted and fixed to the outer periphery of the sound insulation case 31. At this time, the outer circumference of the inner lid 35 is in close contact with the inner circumference of the cup 30, and plays a role of a seal for preventing scattering of cooking ingredients and the like.

The operation of this embodiment will be described below. Place the cup base 13 on which the user has attached the cup 30 and the base 2
When mounted on 4, the outer circumference of the sound insulation case 31 is fitted and fixed to the main body 34. That is, since the sound insulation case 31 is fixed to the main body 34 and the cup 30 and the cup base 13 are fixed to the motor 10, a gap is maintained between the sound insulation case 31 and the cup 30.

The noise generated when the cooking material is agitated, cut and crushed is shielded by the cup lid 32, the sound insulation case 31, and the main body 34, and is not transmitted to the outside. Also, the cup lid 3
2. The elastic body 14 and the inner lid 35 are in contact with each other between the main body 34, the sound insulation case 31, the cup 30, the cup base 13, the motor 10 and the like. Since both the elastic body 14 and the inner lid 35 are flexible, the vibration is hardly transmitted, and therefore the noise during use is greatly reduced as compared with the conventional structure.

Also, when cleaning up after finishing the cooking,
Even if the sound insulation case 31 is held to remove the cup base 13, the upper end of the sound insulation case 31 is inserted into the folded portion 33 at the upper end of the cup 30, and the lower end is stopped in the gap with the cup base 13, It does not come off from the cup 30, and can be removed only after the cup base 13 is removed from the cup 30.

Also in this embodiment, the air vent hole 3
Since the noise does not directly propagate to the outside from 6 and the area of the air vent hole 36 can be set to be relatively large, the pressure pulsation inside the cup 30 is reduced, which leads to noise reduction.

[0020]

As described above, according to the first means of the present invention, the noise source can be shielded by the fitted cup lid and main body, and the basic number of parts does not change, and the simple structure is used. It is possible to provide an electric cooking machine that significantly reduces noise during use.

According to the second means of the present invention, the same effect as that of the first means can be exhibited by adding the sound insulation case.
