Description

DETAILED DESCRIPTION OF THE INVENTION Conventionally, as shown in FIG. 1, a juicer cools a motor 4 by sucking or exhausting air through a cooling port 3 provided in a side wall 2 of a device main body 1. As a means for improving cooling efficiency, an air guiding body 5 is separately provided on the outer periphery of the motor 4, and air is forcedly taken in or exhausted by a cooling fan 6 to cool the motor 4. However, with this motor cooling method, the vibration noise of the motor 4 directly leaks out from the sides of the main body 1 through air propagation through the cooling port 3, resulting in high noise.In addition, the provision of a separate air guide body 5 reduces costs. It was connected to the up.

The present invention provides a juicer that reduces the noise and costs by improving the cooling port portion.

Hereinafter, one embodiment of the present invention will be described based on FIGS. 2 to 4. In the figure, 7 is a main body with legs 8, 9
11 is a motor mounting foot that is embedded in the bottom plate 10 of the main body 7 and has a boss 13; 14 is a motor mounting foot that is sandwiched between the motor mounting legs 9 and 11; Vibration-proof rubber holding the mounting plate 15, 16u Motor attached to the motor mounting plate 15 and built into the main body 7, 1
7 is a motor cooling fan rotatable integrally with the motor shaft 18 of the motor 16; 19 is a cooling port installed in the substantially annular cooling air guide portion 2o embedded in the bottom plate 1o of the main body 7; It communicates with an air guide section 21 that communicates with the outside of the air guide section 21 . Further, the cooling port 19 is open to the motor 16 side.

The cooling air guide section 2o is located on the outer circumference of the motor 16, and its height is set to reach the vicinity of the windings of the motor 16.

22 is a juice container which is placed on the main body 7 and has a juice container 23 inside and a juice outlet 24 at the bottom;
Reference numeral 5 denotes a tip for receiving the gies dripped from the giesse outlet 24.

Inside the container 22 of the gear receiver, a substantially cylindrical spinner 26 with a larger diameter and rotatable upward is arranged. 27 is a cutter fixed to the inner bottom surface of the spinner 26, and 28 is a substantially cylindrical filter detachably installed inside the spinner 26. The substantially cylindrical filter 26 has a plurality of slits 29 in the axial direction. 3.degree. is a hollow annular body that is coaxial and integrally constructed with the spinner 26. The hollow annular body 30 has a plurality of slits (not shown) to prevent rapid internal movement.
It is equipped with a liquid balancer. The spinner 26 is removably fitted to the output shaft 32 of the motor 16, and is further rotated by the output shaft 32. The juice receiver 33 is a charging cylinder provided on the container lid 34, and the inside thereof is hollow. Reference numeral 35 denotes a push rod for pressing fruits etc. guided into the input tube 33 against the cutter 27. 36 is motor mounting foot 9, 11
This is a mounting screw that connects the 3 is a forced exhaust or intake window provided on the bottom plate 1o, and 38 is a side wall of the main body 7.

Next, the operation of the juicer of the embodiment will be explained.

After the output shaft 32 of the motor 16 starts rotating in the direction of the arrow, the object to be cut, such as fruit, is pressed against the cutter 27 by the push rod 36 from the input cylinder 33 and crushed.

As the grinding continues, the motor 16 generates heat, but at this time, the motor cooling fan 17 also rotates in the direction of the arrow, causing cooling air to be exhausted (or taken in) through the window 37, and further through the air guide section 21. Cooling air is taken in (or exhausted) through the cooling port 19 in the direction of arrow Q (or in the opposite direction). The motor 16 is cooled by this cooling air. Needless to say, since there is no air window in the side wall 38, the vibration noise of the motor 16 is not transmitted through the air. Further, the lees (not shown) pulverized by the cutter 27 are applied with centrifugal force by the rotation of the spinner 26 and adhere to the inner surface of the substantially cylindrical filter 28, and the juice is separated.

The juice rises up the inner wall surface of the spinner 26 and is discharged from above 1, and is further dripped into the cup 25 from the juice outlet 24 via the juice receiver part 23. On the other hand, the dregs of the youth are stored inside the substantially cylindrical filter 28, that is, inside the spinner 26.

Next, another embodiment of the present invention will be described based on FIGS. 5 and 6. In the figure, reference numeral 39 indicates a plurality of cylindrical cooling air holes installed in the bottom plate 10 of the main body 7. Cooling ports provided in the guide part 40 are air guide parts 4 that communicate with the outside of the main body 7.
It communicates with 1. Further, the cooling port 39 is open to the motor 16 side. This embodiment differs from the previous embodiment in the configuration of the cooling air guide section 4ol, but is otherwise the same.

In this embodiment, as the motor cooling fan 17 rotates in the direction of the arrow, cooling air is exhausted (or taken in) through the window 37, and the cooling air is further directed in the direction of the arrow Q ( or in the opposite direction). The motor 16 is cooled by this cooling air. Further, since there is no air window in the side wall 38, the vibration noise of the motor 16 is not transmitted through the air.

As is clear from the above embodiments, in the GISA of the present invention, the vibration noise of the motor is not directly propagated through the air to the outside of the main body, so the noise is reduced, and the cooling air guide installed in the bottom plate of the main body Since the section also functions as a conventional separately installed air guiding body, it is possible to reduce costs.
