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 guide body 5 is separately provided on the outer circumference of the motor 4, and air is forcedly taken in or exhausted by a cooling fan 6 to cool the motor 4. However, in this motor cooling method, the vibration noise of the motor 4 directly leaks out of the apparatus main body 1 through air propagation through the cooling port 3, resulting in high noise. Furthermore, providing the air guide body 6 separately leads to an increase in cost.

The present invention provides a juicer that achieves the above-mentioned noise reduction and cost reduction by improving the cooling port portion.

Hereinafter, one embodiment of the present invention will be described based on FIGS. 2 and 3. In the figure, 7 is a main body with legs 8, 9
11 is a plurality of motor mounting feet implanted in the bottom plate 10 of the main body 7 and has a boss 13; 14 is the motor mounting foot 9.11.
anti-vibration rubber, 16, which is held between and holds the motor mounting plate 15;
17 is a motor cooling fan that is rotatable integrally with the motor shaft 18 of the motor 16; 19 is a cooling port provided on the motor mounting leg 9; , are open in the tangential direction arrows A, B, and C of the outer circumference of the motor 16. Reference numeral 20 denotes a juice container placed on the main body 7 and having a juice receptacle portion 21 and a juice outlet 22 at the bottom, and 23 a tip for receiving the juice dripped from the juice outlet 22.

In the juice receiver, a substantially cylindrical spinner 24 that is rotatable in a large diameter upward is arranged inside the container 2Q. 25 is a cutter fixed to the inner bottom surface of the spinner 24, and 26 is a substantially cylindrical filter detachably installed inside the spinner 24. The substantially cylindrical filter 26 has a plurality of slits 27 in the axial direction.

Reference numeral 28 is a hollow annular body coaxially and integrally formed with the bases 21-24. The hollow annular body 28 has an appropriate amount of liquid 29 inside, and is further provided with a plurality of slits (not shown) to prevent rapid movement of the liquid 29, thereby forming a liquid balancer. There is. The spinner 24 is
It is adapted to be removably fitted to the output shaft 30 of the motor 16, and further rotated by the output shaft 30. Reference numeral 31 denotes a feed tube provided on the container lid 32, and the inside thereof is hollow. Reference numeral 33 denotes a push rod for pressing fruits etc. guided into the input cylinder 31 against the cutter 25. Reference numeral 34 denotes a mounting screw that fastens between the motor mounting legs 9 and 11. 35 is a window for forced exhaust or intake provided on the bottom plate 1o. 36 is a side wall.

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

When the output shaft 3o of the motor 16 starts rotating in the direction indicated by the arrow, the object to be cut, such as fruit, is pressed against the cutter 25 by the push rod 33 from the input cylinder 31 and is crushed. As the grinding continues, the motor 16 generates heat, but at this time, the rotation of the motor cooling fan 17 in the direction of the arrow blows the cooling air to the window 35.
The motor 16 is cooled by exhausting (or taking in) air from the cooling port 19 and then taking in (or exhausting) air from the cooling port 19 . At this time, the air flows in the direction of arrow Q (or in the opposite direction), which is the same as the direction of rotation of the motor cooling fan 17, so that the air flows smoothly and provides effective cooling.

The lees (not shown) pulverized by the cutter 25 are applied with centrifugal force by the rotation of the spinner 24 and land on the inner surface of the substantially cylindrical filter 26, whereupon the juice is separated. The ghee ascends the inner wall surface of the spinner 24 and is discharged from above, and is further dripped into the spout 23 from the ghee outlet 22 via the ghee receiver 21.

On the other hand, the dregs of the jujube is stored inside the substantially cylindrical filter 26, that is, inside the washer 24.

As is clear from the above embodiments, the juicer of the present invention is
A motor cooling port is provided on the motor mounting foot to prevent the vibration noise of the motor from directly propagating through the air outside the main unit.
In addition to reducing noise, the motor mounting foot can be easily positioned near the motor, the cooling port can be placed closer to the motor, and there is no need to provide a separate air guide as in the past, resulting in lower costs. .
