Description

Damping structure of motor vibration

The present invention relates to a juicer for producing fruit or vegetable juice by using a centrifugal separation method, and more particularly, having a dustproof member at a portion where the motor and the body which generate the centrifugal force through rotational force are fastened and coupled. It is related to the motor vibration damping structure of the juicer to be fixed to the body with a spring to reduce the horizontal component during the high speed rotation of the motor, to increase the vertical component, thereby minimizing the vibration generated when the motor is driven.

In general, juicers squeeze juice from foods such as fruits and vegetables, and it is most common to use the centrifugal force provided from the rotational force providing means to extract and extract juices with liquid components of food.

Here, a typical example of the juicer using the centrifugal separation method through the rotational force providing means as described above is shown in FIG. 1, which is briefly described below.

As shown, the juicer supports the motor 51 which generates the rotational force by the supplied electric force from the outside and forms the exterior of the product and the rotational force from the motor 51 of the body 52. Safety incident and isolation of the rotating centrifugation tank 53 from the outside while having a centrifugation tank (53) that is provided and rotated, and a material inlet (54) for supplying food to the centrifugation tank (53) and Cover 55 to form an appearance to prevent foreign matter from entering, press-fit rod 56 provided to press the food introduced through the material inlet 54 of the cover 55, and the press-in rod 56 as described above Filter 57 for filtering out particles of solid components, which are inserted into the inside of the centrifugation tank 53 and ground, with the aid of the filter, and the filter 57 and the centrifugation tank 53 The juice is extracted separately from the residue Is composed of a juice guide 58 to gather to the place, the juice guide (58) receiving the juice juice container (59) being gathered in and the like.

Of course, the power connection between the centrifugal tank 53 and the motor 51 fixed to the body 52 is limited to the movement in the rotational direction of each other and the linear movement facing each other in the free coupling structure and the body 52 and The decomposition and coupling with the centrifugation tank 53 can be made easily, and the inside of the centrifugation tank 53 is a rotary blade is actually installed to sculpt the food.

The juicer configured as described above is controlled by operating a power switch (not shown) provided in the body 52. When the power switch is turned on, the motor 51 rotates to When rotating the centrifugation tank 53, the food is fed into the centrifugation tank 53 is rotated as described above using the press-fit rod 56, the rotary blade of the centrifugation tank 53 is introduced. The food is sliced, the juice generated from the food broken into small particles as described above is extracted to the outside of the centrifugation tank 53 by the centrifugal force in accordance with the rotation of the centrifugation tank (53).

That is, the broken food is in a state in which the solid and liquid components are mixed with each other is moved to the inner wall side of the centrifugation tank 53 by the centrifugal force by the rotating centrifugation tank 53, the centrifugation tank 53 The solid component is filtered out by the filter 57 located on the inner wall of the filter, and the remainder is liquid juice, and then to the outside of the centrifugation tank 53 through the holes of the filter 57 and the centrifugation tank 53. Spills.

The juice extracted as described above is gathered at a predetermined position by the juice guide 58 to be guided into the juice container 59 so that the user can use the juice collected in the juice container 59.

In the juicer configured and operated as described above, referring to the coupling structure of the motor 51, as shown in FIG. 2, the upper end portion and the stop portion of the motor 51 have buffering members 61 and 62 having cushioning properties. It is supported on the inside of the body 52, the drive shaft of the motor 51 is coupled to the centrifugation tank 53 through the coupling 53a, the centrifugation tank 53 and the motor 51 Synchronously flows coaxially by the coupling 53a.

However, in the coupling structure of the motor as described above, there are some problems caused by the vibration of the motor. That is, when the motor rotates at a high speed, the centrifugal tank coupled vertically by the increased horizontal component is eccentric and deteriorates the vertical force to suppress the eccentricity of the motor and the centrifugal tank. There is a problem.

In addition, since the motor generating vibration as described above is simply supported by the fixing member, the vibration generated from the motor is transmitted to the body and the peripheral parts without being attenuated through the fixing member to induce noise. The problem is that the operation of is unstable and quiet.

Accordingly, the present invention is conceived in view of the above-described conventional problems, the motor vibration of the juicer to minimize the vibration generated when the motor is driven by reducing the horizontal component during high-speed rotation of the motor to increase the vertical component The purpose is to provide a damping structure.

Furthermore, it provides a motor vibration damping structure of the juicer, characterized in that the lower center of the motor is fixed to the body by elastic means.

Hereinafter, an embodiment of the present invention will be described in more detail based on the accompanying drawings.

As shown in FIGS. 3 and 4, the motor vibration damping structure of the juicer according to the embodiment of the present invention has a body 152 such that the motor 151 transmits the rotational force to the centrifugation tank 153 about the vertical direction. Applied to the juicer having a structure that is coupled to the inside of the dustproof member 163, 164 is fitted to the site where the motor 151 and the body 152 is coupled and coupled, the lower center of the motor 151 is elastic It is secured to the body 152 by means 170.

The dustproof members 163 and 164 have a cylindrical shape and are fitted to the screw 160 which fastens the upper end of the motor 151 and the body 152. That is, the anti-vibration members 163 and 164 are made of a buffer material such as rubber or silicon so as to be positioned at upper and lower surfaces of the through hole 152a of the body 152 into which the screw 160 is fitted, thereby penetrating the body 152. The screw 160 that is fastened to the fastening hole 151a of the motor 151 by passing through the ball 152a does not directly contact the body 152.

In addition, the elastic means 170 is made of a tension coil spring, one end is fixed to the bracket 151b attached to the center of the lower surface of the motor 151, and the other end is on the vertical axis of the motor 151, that is, It is fixed to the inner surface of the body 152 on the same axis as the center of the motor 151.

In the figure, reference numeral 153a is a coupling connecting the drive shaft of the motor 151 and the centrifugal tank 153, and 155 is a material inlet 154 for supplying food to the centrifugal tank 153. It is provided with a cover to form an exterior to isolate the rotating centrifugal tank 153 from the outside to prevent safety accidents and foreign matter inflow, 157 is inserted into the inside of the centrifugal tank 153 is ground food waste Is a filter for filtering particles of a solid component of phosphorus, 158 is a juice guide to collect the juice is separated from the residue by the filter 157 and the centrifugation tank 153 to one place, 159 is a juice guide It is a juice container that receives the juice gathered at (158).

Looking at the operation of the subject innovation is configured as follows.

First, when the power switch is "on" to operate the juicer, as the power is applied to the motor 151 coupled to the lower portion of the body 152 generates a rotational driving force. At this time, the rotational driving force of the motor 151 is transmitted to the centrifugation tank 153 integrally coupled through the coupling 153a while using the centrifugal force to extract the juice to extract the juice.

In this process, the centrifugal tank 153 is to be caused to be eccentric like the motor 151 by the horizontal component due to the high-speed rotation of the motor 151, the motor 151 at this time is the lower center of the elastic means ( By being fixed to the body 152 vertically by the tension coil spring (170) it is elastically suppressed that the centrifugation tank 153 and the motor 151 is eccentric.

That is, the tension coil spring for fixing the motor 151 to the body 152 is a rotating body of the motor 151 by suppressing and reducing the horizontal component to increase in the high-speed rotation of the motor 151 and increasing the vertical component ) And the centrifugation tank 153 to minimize the generation of vibration as the eccentric.

On the other hand, in the process of being attenuated as the vertical component is increased as described above, the motor 151 is in direct contact with the screw 160 and is not coupled to the body 152 and passes through the dustproof members 163 and 164. Since the vibration from the motor 151 is coupled to the body 152 is suppressed by the dustproof members 163 and 164 surrounding the screw 160 before being transmitted to the body 152 through the screw 160. It is destroyed. That is, the vibration transmitted from the motor 151 is transmitted to the body 152 while the energy is dissipated by the buffering force of the anti-vibration members 163 and 164 without reaching the body 152, thereby eventually reaching the body 152. Only vibration in a significantly reduced state is to be transmitted to the body 152.

As described above, the present invention has a vibration-proof member at a portion where the motor and the body generating the centrifugal force through the rotational force is fastened and coupled, and the lower center of the motor is fixed to the body with a spring to reduce the horizontal component during the high speed rotation of the motor. By increasing the vertical component, the vibration generated when the motor is driven can be minimized.

Therefore, the present invention can suppress the generation of noise due to the vibration from the motor, there is an effect to make the operation of the juicer more stable and quiet.
