Body for juicer {body for juice or crush apparatus}

The present invention relates to a juicer body in which a motor housing provided with a pair of foot in which an elastic member made of rubber is installed is fixed to a base plate.

In general, as shown in FIG. 8, the juicer is largely fitted into the main body 100, the screw rod 120, the screw rod 120, the screw rod 120, and the juice container 130 It consists of a housing 140, a cap 150 is coupled to the housing 140, the discharge cap 160 is coupled to the cap 150. The rotating shaft 122 of the screw rod 120 is coupled to the main body 100 to receive the rotational power.

One end of the housing 140 is coupled by a binding ring 114 of the main body 100, and the other end supports the cap 150. In the housing 140, an inlet 143 is formed on the upper surface, and a juice outlet 146 is formed on the lower surface. The inlet 143 is preferably provided with a hopper 144 to facilitate the injection of the adherent juice. The residue is discharged to the outside through the discharge cap 160 coupled to the cap 150. Here, it will be apparent that the juice container 130 may serve as a grinder when the juice container 130 intersects in a grinding container (not shown).

Through such a configuration, the juicer is a device for transferring juice to the outside through the juice container 140 in the order of grinding and pressing while transferring the adhered juice along the screw rod 120.

As described above, the main body 100 is coupled to the motor 101, the motor support motor housings 103a and 103b, and the motor housing 103b, and receives the rotational power of the motor 101 to receive a screw. It consists of a reduction gear device 105 to be transmitted to the rod 120, a base plate 107 on which the motor housings 103a and 130b are mounted, and a case 109 coupled to the base plate 107.

A downwardly protruding protrusion plate 105a is formed in the housing of the reduction gear device 105 coupled to the motor housing 103b. The protrusion plate 105a is provided with a through hole through which the male screw body 112a is fitted.

The base plate 107 is provided with the bracket 110 in the position which opposes this protrusion plate 105a. The bracket 110 is formed with a channel 110b at a position facing the through hole.

Therefore, the nut 112b is provided through the washer while the body of the male thread body 112a fitted to the protrusion plate 105a is supported at the bottom of the channel 110a while the protrusion plate 105a and the bracket 110 overlap each other. By engaging with, the power train is fixed to the base plate 107.

However, this fixing method is made of a material in which the protrusion plate 105a and the bracket 110 are hard to each other. Thus, friction occurs with each other due to vibrations caused by the rotation of the motor, thereby generating noise.

In addition, in the fastening method of the male screw 112a and the nut 112b, loosening of the nut 112b may occur due to vibration or friction. Therefore, the fixing of the power transmission device may be unstable, adversely affecting the main body, and significantly lowering the green juice efficiency.

In addition, the case 109 and the base plate 107 are coupled to each other so that the motor rotational vibration is transmitted from the base plate 107 to the case 109 and the case is shaken. Therefore, severe noise may be further generated to give a user an inconvenience such as stress.

In addition, since the protrusion plate 105a and the bracket 110 protrude from each other, the height of the case 109 may be increased, thereby increasing the size of the main body.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a juicer main body having a structure capable of absorbing the vibration generated by the rotation of the motor as much as possible and reducing the height of the case.
