Description

[Detailed description of the invention] The present invention relates to an automatic cleaning type juicer that can dispose of lees and clean it after use without removing the lid or centrifugal separation function. It also relates to improvements to improve the efficiency of lees disposal and washing.

Generally, a juicer houses a centrifugal separation capacity within the main body case, and a lees holder is placed around the separation capacity.
The separation unit is rotated at high speed to cut vegetables, fruits, and other materials into thin pieces at the inner bottom of the separation unit, and the resulting juice is passed through the filter on the peripheral wall of the separation unit by centrifugal force, and then exits from the juice outlet provided in the main body case. The sludge is taken out to the outside and the sludge is discharged into the sludge tray from the upper opening edge of the separation capacity.

However, with conventional juicers of this type, the lid that blocks the upper opening of the juice receiver must be removed, the centrifugal separation function must be removed, the dregs must be discarded, and the inner surface of the main body case, filter, etc. must be removed each time the juicer is used. After cleaning, it has to be reassembled, which has the disadvantage of consuming a lot of time and effort for discarding scum after use, cleaning, and assembling.

Therefore, in recent years, self-cleaning juicers have been developed that allow the waste to be disposed of and cleaned after use without removing the lid or centrifugal separation function.

This is done by filling the main body case with water and rotating the centrifugal separation unit to generate a rotating water flow inside the lees receiver placed around the separation unit. It is configured to allow the juice to flow out and be discharged to the outside from the juice outlet.

However, using only a rotating water flow, a lees tray requires a large amount of water to flush out the lees inside, making it less efficient.

Therefore, the lees receiver has a lees discharge port in a part of the section, and this discharge port is normally closed with an opening/closing plate, and when cleaning, the lees discharge port is opened so that the lees inside the lees receiver can flow out quickly. However, it is troublesome to manually operate the opening/closing plate every time cleaning is performed, and there is also a risk that the opening/closing plate may be used in a state where the opening/closing plate is forgotten to be closed.

Furthermore, it is difficult to remove dregs and the like adhering to the filter using only a rotating water stream, and there is also the drawback that a large amount of water is required.

This idea was created based on these circumstances.
In addition to being equipped with a filter cleaning tool consisting of a brush connected to the tip of a holder that has a water supply channel inside, the lees receiver has a lees discharge port in a part of the part, and the discharge port is always closed with an opening/closing plate. , the lid body is provided with a brush insertion port, through which the brush of the cleaning tool is introduced into the centrifugal separation capacity, and the filter of the separation capacity can be cleaned with the brush;
Furthermore, cleaning water is sprayed near the opening/closing plate of the sludge tray through a water supply channel provided in the holder of the cleaning tool, and the opening/closing plate is opened at the same time as water is supplied, thereby solving the various drawbacks mentioned above at once. The purpose of the present invention is to provide a self-cleaning juicer that can clean the juicer.

This cleaning tool 29 has a brush 3 connected to one end of a tubular holder 30 having a water supply channel 30a inside through a connecting member 31.
2 are hingedly connected.

The water supply channel 30a intersects a hole drilled in the axial direction from one end of the holder 30 and a through hole drilled in the diametrical direction near the other end, so that water flows in from the one end side of the holder 30. The water is injected from side openings 30b and 30c near the other end.

Further, the outer diameter of the other end of the holder 30 is slightly smaller, and a flexible hose (for example, a bellows hose) 33 can be connected to this portion to connect it to a water faucet or the like.

Further, on the outer periphery of the holder 30, the l pairs of through holes 18a are provided.
, 18b are provided with a pair of upper and lower annular grooves 34a, 34b at approximately the same interval as the interval between the grooves 34a, 18b.

The connecting member 31 has both ends formed in a bifurcated shape, and one end of the connecting member 31 is hinge-connected with a pin 31a so as to sandwich one end of the holder 30, and the other end is connected to the back plate 32 of the brush 32.
It is hinge-connected with pins 31b so as to sandwich the parts a.

Further, a stopper 35 is provided on the side surface of the connecting member 31, so that the brush 32 can be moved approximately 90 degrees relative to the connecting member 31.
It can be rotated within a range of °.

Therefore, when making juice from vegetables, fruits, etc. using this juicer, place a spoon 36 below the juice outlet pipe 6, pull up the cleaning tool 29 as shown in FIG. b is locked to the locking edge 22C of the cap 22, and the side opening 30b of the water supply channel 30a provided in the holder 30 is aligned with the upper through hole 18H.

Then, the holder 30, the connecting member 31 and the brush 3
2 are almost in a straight line, and the brush 32 is connected to the filter 11.
The brush guide 19 is held at a position above the brush guide 19.

Therefore, the motor 1 is driven to generate stirring blades 7 and centrifugal separation capacity 10.
Rotate 1. Input the ingredients to be made into juice into the material input port 15.
a into the centrifugal separator 10, and push it through the push rod (
(not shown), the material is finely cut by the cutter 12 that rotates at high speed, and the juice passes through the filter 11 and is discharged into the juice receiver 24, and then passes through the juice outlet pipe 6 to the spout 36. flows inward.

On the other hand, the squeezed lees squeezed by the filter 11 passes over the upper edge of the filter 11 and is discharged into the container 23.

At this time, the brush 32 of the cleaning tool 29 is separated from the filter 11 with a centrifugal separation capacity of 10 and is held above the brush guide 19 provided on the outer surface of the material input cylinder 15, so when making juice The brush 32 and the connecting member 31 do not get in the way, and the juice and dregs do not get in the way.
There is no problem with it adhering to the surface.

Of course, when making juice, the cleaning tool 29 may be removed. To remove the cleaning tool 29, rotate the cap 22 and remove the locking edge 22 from the annular groove 34b of the holder 30. This can be easily done by pulling out the brush 32 as a unit from the introduction port 16.

When the cleaning tool 29 is removed to make juice,
Since the insertion port 16 is located directly above the brush guide 19, no juice will be splashed to the outside from here.

After producing juice in this manner, the inside of the juicer body 3 can be cleaned as follows.

That is, as shown in FIG. 6, with the lower annular groove 34b locked with the locking edge 22 of the cap 22, the open end of the juice outlet pipe 6 is positioned above the sink, and the hose 33 is connected to the holder. 30 to a water faucet to supply water.

Then, the cleaning water passes through the water supply channel 30a and a part of it flows through the side opening 30b and the through hole 18a into the material input tube 1.
5 to clean the inside of the charging cylinder 15, and the other part is sprayed from the side opening 30C to the opening/closing plate 26 in the container 23.
Spray nearby.

The washing water in the material input tube 15 passes through a filter 11 with a centrifugal separation capacity of 10, and the washing water in the lees container 23 flows down into the juice receiver 24 through a notch 26 or a draining hole 27.

Therefore, the motor 1 is driven to generate stirring blades 7 and centrifugal separation capacity 10.
When the juice receiver 24 and the lees receiver are rotated at high speed, a rotating water flow is generated inside the container 23. In particular, in the lees receiver, the water supply channel 3 of the brush holder 30 is located near the opening/closing plate 26 inside the container 23.
Since the washing water is injected through the sludge discharge port 25, the water pressure in the vicinity increases and presses the opening/closing plate 26 from the inside, causing the opening/closing plate 26 to quickly open as shown in Figure 4. to open.

The lees receiver is the lees outlet 25, and the rotating water flow inside the container 23 is the lees outlet 25.
The lees flows through the container 23 and flows into the juice receiver 24.
The lees accumulated inside the juice container are swept away by the water flow and are discharged into the juice receiver section 24.

Further, relatively coarse lees are finely cut by blades formed on the stirring blades 7 in the juice receiver section 24, and are discharged to the outside through the juice outlet pipe 6.

With the above, the inside of the material input cylinder 15 and the juice receiver are connected to the part 24.
The inner surface of the filter 1 is cleaned, and at the same time, the lees in the container 23 is automatically discharged from the lees receiver.
The dregs adhering to the inner surface of 1 can be removed as follows.

That is, in the state shown in FIG. 6, rotate the cap 22 to remove the locking edge 22C from the lower annular groove 34b,
When the holder 30 is lowered and the upper annular groove 34a is locked with the locking edge 22C, the side opening 30b of the water supply channel 30a provided in the holder 30 is inserted into the lower through hole 18b. Match.

On the other hand, as the holder 30 descends, the connections between the holder 30 and the connecting member 31 and between the connecting member 31 and the brush 32 are bent as shown in FIG. 1, and the back plate 32a of the brush 32 is bent. By slidingly contacting the guide surface 19a of the brush guide 19, the brush 32 comes into contact with the entire inner surface of the filter 11 with approximately equal pressure.

When water is supplied through the holder 30, part of the cleaning water is injected into the material input tube 15 through the side opening 30b and the through hole 18b, and the other part is injected into the material input cylinder 15 through the side opening 30b.
C and is injected to the inner surface of the filter 11.

Therefore, when the motor 1 is driven to rotate the centrifugal separator 10 at high speed, the dregs adhering to the entire inner surface of the filter 11 are reliably and quickly removed by the brush 32, and the lees receiver passes through the container 23 from the upper edge of the separator 10. Directly into the juice receiver 24 or through the filter 11
The juice is discharged into the interior and further discharged to the outside through the juice outlet pipe 6 by the rotating water flow.

As described above based on the embodiments, according to the juicer of the present invention, the lees outlet 25 is provided in a part of the lees receiver (the lees receiver is the container 23), and the lees outlet 25 is closed. Since the cleaning water is sprayed near the opening/closing plate 26, the opening/closing plate 26 can be opened quickly at the same time as the water is supplied, and with a small amount of water, the lees in the lees tray 23 can be quickly flushed out. be able to.

The opening/closing plate 26 is automatically opened by the rotating water flow generated in the lees tray 23, so there is no need for manual operation, and the opening/closing plate 26 closes at the same time as the rotating water flow disappears, so it can be used even if you forget to close it. There is no risk of doing so.

Furthermore, water is supplied to the brush holder 30 of the filter cleaning tool 29.
Since the washing is carried out through the water, the filter 11 can be washed with the washing tool 29, and the filter 11 can also be washed with a small amount of water.

Note that the present invention is not limited to the configuration of the embodiments, and can be implemented with various modifications.

For example, the filter cleaning tool 29 may have a brush 32 directly connected to the tip of the holder 30.

Further, the stirring blade 7 is not necessarily required.

Furthermore, the position of the lees discharge port 25 can also be changed as appropriate.
