Description

[Detailed description of the invention] The present invention relates to an automatic cleaning type juicer that can dispose of waste and clean it without disassembling it, and in particular, it relates to an improvement to improve cleaning efficiency and operability 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 from the peripheral filter part of the basket, and then sends it to the juice outlet. The strained lees is 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 after use and clean it without disassembling 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 surrounding 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. However, 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. It is conceivable to have a structure in which the dregs are quickly flowed out from the opening, and after cleaning, the opening is closed or operated again to prepare for the next use.

However, in this case, the structure becomes complicated due to the provision of the opening/closing plate, and troublesome opening/closing operations are required.Furthermore, if the closing operation is forgotten after cleaning, lees may get mixed into the juice the next time the juice is made. There was a problem that could lead to this.

The present invention was developed based on these circumstances, and its purpose is to generate a rotating water flow in the lees receiver provided around the centrifugal separation basket and to cause the lees in the lees receiver to flow out to the juice receiver. In the self-cleaning juicer,
The purpose is to improve the efficiency and operability of waste disposal and cleaning through a simple structure.

In addition, on the outer periphery of the water supply pipe 30, the pair of through holes 18 a,
A pair of upper and lower annular grooves 34 are provided at an interval equal to 18 b.
a, 34b are provided, and the center hole of the water supply pipe 30 is opened at the lower end of the side surface.

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, a cup 36 or the like is placed below the juice outflow pipe 6, and the cleaning tool 29 is pulled up as shown in FIG. 34 b cap 2
2, 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 19a, 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 cut into thin pieces 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, and due to the wind pressure generated by the rotation of the separation basket 10, the lees rotating inside the lees receiving container 23 in the direction of the lees discharge port 25 as indicated by the arrow in FIG.

While the lees discharge port 25 is upstream, there is a full board 2.
7 is provided, most of the lees is loaded on the upstream side of the baffle plate 27, and the remaining lees is also loaded on the baffle plate 27.
It hits the partition plate 26 by riding the low-speed wind that bypasses it, and is deposited on the surface of the partition plate 26.

Therefore, when making juice, the lees discharged from the upper edge of the centrifugal separation basket 10 will not pass through the outlet 25 of the lees receiving container 23 and be discharged to the juice receiving portion 24.

Juicer body 3 after making juice in this way
The inside can be cleaned as follows.

That is, the cleaning tool 29 is lowered and the upper annular groove 34 a
is locked by the locking edge 22C of the cap 22 to align the lower end opening of the water supply pipe 30 with the lower through hole 18b.

Then, the brush 32 comes into contact with the inner surface of the filter 11, so in this state, the open end of the juice outflow pipe 6 is positioned above the sink, and water is supplied into the main body case 4 through the cleaning tool 29.

Then, a part of the cleaning water is injected into the material input tube 15 through the through hole 18b to clean the inside of the material input tube 15, and the other part is injected along the inner surface of the lid body 5 to clean the inside of the material input tube 15. is washed and flows down into the lees receiving container 23.

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.

Then, this rotating water flow swirls inside the lees receiving container 23, bypasses the baffle plate 27, flows out from the lees discharge port 25, and sweeps the lees in the lees receiving part 23 into the juice receiving part 24.

Of the lees flowing into the juice receiving portion 24, coarse ones such as thin apple skins are finely cut by the blades of the stirring blades 7, and are discharged to the outside through the outflow pipe 6 along with other lees.

Furthermore, the dregs adhering to the inner surface of the filter 11 can also be removed by the brush 3.
2, it is peeled off and discharged to the outside together with other dregs.

As described above based on the embodiments, the juicer of the present invention has a radial stepped portion formed on the inner peripheral wall of the annular lees receiving portion (lees receiving container 23), and an opening ( Since a lees discharge port 25) is provided and a baffle plate 21 is provided on the upstream side of the rotating water flow near the opening, the lees can be quickly discharged through the opening.
Cleaning can be made more efficient.

Also, the opening is always open, but when making juice, the lees are not discharged from the opening due to wind pressure, and when washing, the lees are discharged from the opening by the rotating water flow. The desired effects can be achieved, such as eliminating the trouble of opening and closing the opening and eliminating the risk of forgetting to close the opening.

If the partition plate 26 is bent downstream to form a shape 26' as shown in FIG. This makes it possible to more reliably prevent the lees from being discharged from the opening (the lees discharge port 25).
