Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic cleaning juicer that can perform lees disposal and cleaning without disassembly, and particularly relates to an improvement for increasing cleaning efficiency with a simple structure.

Generally, a juicer rotates a centrifugal separation basket at high speed inside the main body case, finely cuts the material to be made into juice at the inner bottom of the basket, discharges the juice through a part of the filter on the peripheral wall of the basket, and then flows it into the juice stream. The strained lees is discharged to the outside from the outlet and discharged from the upper opening edge of the basket to a lees receiving portion provided around the upper opening edge of the basket.

Therefore, after use, it must be disassembled, the squeezed lees accumulated in the lees receiver must be discarded, and the inside of the main body case must be cleaned and reassembled. It had the disadvantage of requiring a lot of time and effort.

Therefore, in recent years, an automatic cleaning type juicer has been developed that can dispose of the dregs and clean it after use without having to disassemble it.

After use, water is poured into the main case and the basket is rotated to generate a rotating water flow inside the main case.The rotating water flow cleans the inside of the main case and removes the lees from the lees receiver into the juice receiver. The juice was then discharged to the outside through the juice outlet.

However, in this case, the lees in the lees receiver will flow out over the peripheral wall of the lees receiver, which requires a large amount of water, and it takes a long time for all the lees in the lees receiver to flow out. The drawback was that the cleaning efficiency was very poor.

In order to eliminate this drawback, an opening for discharging lees is provided on the peripheral wall of the lees receiver, and this opening is normally closed with an opening/closing plate.When cleaning, this opening is opened and the inside of the lees receiver is opened. A conceivable structure is to allow the lees to quickly flow out from the opening, and after cleaning, close the container again to prepare for the next use.

However, in this case, there is a hassle of opening and closing the opening/closing plate.
Moreover, if you forget to close the lid after washing, there is a problem that the next time you make juice, lees will get mixed into the juice.

Therefore, the inventors of the present invention mounted the opening/closing plate rotatably, kept it in the closed position at all times with a spring, and created a rotating water flow inside the lees receiving part when cleaning. The idea was to have the opening/closing plate automatically pushed open from the inside by the pressure of the water flow.

In this way, the opening/closing plate can be opened automatically, and the opening/closing plate can be automatically closed due to the disappearance of the rotating water flow, so that the above-mentioned disadvantages can be solved.

However, in this case, when the opening/closing plate is in the closed position, the pressure of the rotating water flow is applied almost perpendicularly to the inner surface, so it rotates relatively easily in the opening direction at first, but the amount of rotation increases. Accordingly, the pressing force of the water flow comes to act on the inner surface of the opening/closing plate at an acute angle, and the actual pressure for opening the opening/closing plate, that is, the component force in the direction perpendicular to the inner surface of the opening/closing plate, gradually decreases. become.

For this reason, the opening/closing plate cannot be opened wide enough,
As a result, there was a problem in that the lees in the lees receiving section could not be quickly drained out.

This invention was developed based on these circumstances.
The purpose of this is to provide an automatic cleaning juicer in which the lees in an annular lees receiver disposed around a centrifugal separation basket is discharged by a rotating water flow. This opening is always closed by a rotatable opening/closing plate, and is opened wide by the rotating water flow to quickly drain the dregs, thereby improving cleaning efficiency.

Hereinafter, the structure of the present invention will be explained based on embodiments shown in the drawings.

The brush 32 is rotatably supported at the tip of the link 31, and its range of rotation is restricted by an L-shaped stopper 35 provided on the link 31.

Therefore, when making juice of vegetables, fruits, etc. using this juicer, place a cup 36 or the like below the juice outflow pipe 6, and pull up the cleaning tool 29 as shown in FIG. The groove 34b is locked by the locking edge 22C of the cap 22, and the lower end opening of the water supply pipe 30 is aligned with the upper through hole 18a.

Then, the brush 32 separates from the filter 11, contacts the guide surface 19H, and is held in a substantially vertical state.

Therefore, the motor 1 is driven to drive the stirring blades 7 and the centrifugal separation cage 10.
When the material to be made into juice is put into the material input cylinder 15 and pressed against the cutting blade 12 with a push rod (not shown), the material is finely cut by the cutting blade 12 rotating at high speed. The juice passes through the filter 11 and is discharged to the juice receiving portion 24, and then flows out from the outflow pipe 6 into the cup 36.

On the other hand, the squeezed lees squeezed by the filter 11 is
1 and is discharged into the lees receiving container 23.

After making juice in this way, the juicer body 3
The inside can be cleaned as follows.

Therefore, the motor 1 is driven to drive the stirring blades 7 and the centrifugal separation cage 10.
When the main body case 4 is rotated at high speed, a rotating water flow is generated inside the main body case 4.

As a result, the opening/closing plate 26 is pushed from the inside by the rotating water flow and rotates in the opening direction as shown by the imaginary line in FIGS. 3 and 4.

As the amount of rotation increases, the pressing force of the rotating water flow comes to act on the inner surface of the opening/closing plate 26 at an acute angle.
1 acts as a resistance to the rotating water flow, and in particular, since this protrusion 27 is provided near the rotating end of the opening/closing plate 26, the opening/closing plate 2
6 opens wide under the strong pressure of the rotating water stream, and the lees in the lees receiving container 23 quickly flows out into the juice receiving part 24 and is discharged to the outside from the juice outflow pipe 6.

Note that some of the lees may contain large particles such as the thin skin of an apple, but such coarse lees are finely cut by the blades formed in the stirring blades 7, so that the lees does not flow through the outflow pipe. The lees discharged from 6 does not contain large particles,
Therefore, it can be disposed of directly into the drain, eliminating the hassle of garbage disposal.

Further, the dregs adhering to the inner surface of the filter 11 are removed by the brush 32 and discharged to the outside together with the dregs and juice adhering to various parts within the main body case 4.

As described above based on the embodiments, according to the present invention, the annular lees receiving part (
In an automatic cleaning type juicer in which the lees in the lees receiving container 23) is discharged by a rotating water flow, a lees discharge port 25 is formed in the lees receiving portion, and the lees discharge port 25 is rotatably kept closed at all times. By providing the protrusion 27 on the inner surface of the opening/closing plate 26, the opening/closing plate 26 can be opened wide with a small amount of water, allowing the lees in the lees receiver to quickly flow out, making cleaning and lees disposal inside the main case more efficient. can do well.
