Description

[Detailed description of the invention] The present invention relates to an automatic cleaning juicer that can be cleaned after use without removing the lid, centrifugal separation capacity, etc., and in particular, it is an improvement to improve the cleaning effect. Regarding.

Generally, a juicer has a juice receiver and a lees receiver in the main body case, and the case houses a centrifugal separation function to rotate the juicer at high speed. The materials to be made into juice are crushed at the inner bottom of the separation basket, and the juice is discharged into the juice receiver through the peripheral wall filter section of the separation basket, and the lees are removed from the upper opening edge of the separation basket. It is configured to be discharged into the room.

However, with conventional juicers of this type, the lid and centrifugal separation function are removed each time the juicer is used, and the lees container is used to discard the lees that has accumulated in the case. This has the disadvantage that cleaning and assembling after use requires more time and effort than making a reuse, as it requires rinsing off the water and juice and reassembling.

Therefore, in recent years, automatic cleaning juicers have been developed that can be cleaned after use without removing the lid, centrifugal separation function, etc.

As shown in FIG. 1, water is poured into a main body case 102 housing a centrifugal separator 101, and the centrifugal separator is rotated to generate a rotating water flow in a part 103 of an annular lees receiver provided around the basket. The rotating water flow causes the lees accumulated in the lees receiver to flow out into the juice receiver below the lees receiver.

However, when a rotating water flow is generated in the annular lees receiver, the lees inside the lees receiver are carried around by the water flow and circulate forever, while the juice receiver does not flow out quickly to the other part.

Therefore, the inventors of the present invention have previously developed a self-cleaning juicer that does not have such drawbacks.

For example, as shown in FIG. 2, the annular lees tray has a bottom wall of a part 103 formed in a spiral shape, and a part thereof has a vertically stepped part 104 which acts as a resistor against the rotating water flow. The lower opening of the portion 104 was used as a lees discharge port 105, and the lees in the portion 103 was configured to quickly flow out by opening the shielding plate 106 that blocked the lees discharge port 105. , this also had the following problems.

That is, if the lees receiver has a vertical step 104 formed in a part of the bottom wall of the portion 103 and the lower opening of the step 104 serves as the lees discharge port 105, the step 1
Since the upper bottom wall end 107 of 04 is shaped like an edge to face the rotating water flow generated inside the lees tray, relatively large lees 108 such as thin apple skin or fibrous material can be removed from the edge-shaped end of the lees tray. 107 and remains in the sludge discharge port 105 without flowing out. As a result, a new problem arises in that excellent cleaning effects cannot be obtained.

The present invention was developed based on these circumstances, and its purpose is to create a rotating water flow inside the ring-shaped lees receiver provided around the basket through the rotation of the centrifugal separation power, and to remove the lees. In an automatic cleaning type juicer in which the lees inside the receiver flows out to the juice receiver, the lees receiver has a vertical step formed on the bottom wall of the section as a resistor against the rotating water flow. The lower opening of the stepped part is used as a lees discharge port to quickly drain the lees in the lees receiver to the juice receiver, and a barrier wall is provided on the soil surface of the upper bottom wall of the step. The purpose is to improve the cleaning effect by preventing the end of the wall from facing the rotating water flow in an edge-like manner and preventing relatively large sludge from getting caught in that part.

When making juice of vegetables, fruits, etc. using the juicer configured as described above, first, the water supply pipe 64 is held in the upper position as shown in FIG.
Open the juice take-out valve 40, place a cup 76 to receive the juice under it, and connect the motor 4.
The material to be made into juice is put into the material input cylinder 54, and the material is pushed into the centrifugation area 25 using a push rod (not shown).
Press it against the inner cutting and raising blade 27.

Then, the material is finely scraped down by the cutting and raising blade 27 rotating at high speed, and the juice is discharged to the juice receiver section 34 through the peripheral wall filter section 26, and flows into the cup 76 from the juice outlet via the take-out valve 40. .

On the other hand, the squeezed lees extracted by the filter section 26 of the centrifugal separation capacity 25 passes over the upper opening edge of the separation capacity 25 and is discharged into the container 32.

Note that when making juice, rotational wind pressure is generated inside the container 32 of the lees receiver due to the rotation of the centrifugal separator 25;
Depending on this wind pressure, the shielding plate 37 cannot be opened.

After making the juice, the inside of the main body case 2 can be cleaned as follows.

That is, the water supply pipe 64 is held in a downward position as shown in FIG. 3, the brush 66 is pressed against the inner surface of the filter section 26, and the opening of the juice take-out valve 40 is positioned above the sink.

When water is supplied through the water supply hose 75, the pressure of the water flow causes the valve body 71 of the flow rate control valve 67 to move against the spring 7.
2, the water separates from the valve seat 73 and flows into the water supply hole 68 of the water supply pipe 64.

A part of it passes through the through hole 56b and enters the material input cylinder 54.
The other part is sprayed into the inside of the lid body 4 to clean the inside.
The lees receiver flows into the container 32 by being injected to the back side of the container 9, and when it overflows from the inner circumferential wall of the container 32, the juice receiver flows down into the part 34.

When the motor 4 is started, the stirring blades 22 and the centrifugal separator 25 rotate at high speed, and a rotating water flow is generated inside the main body case 2. helpful).

At this time, the stepped portion 35 serves as a resistance to the rotating water flow generated in the container 32, and water pressure acts strongly from the inside on the shielding plate 37 placed at the stepped portion 35.
The shielding plate 37 operates to open.

The lees collected in the container 32 is circulated by the rotating water flow, but because of the stepped portion 35, it does not circulate many times, and the lees accumulated in the container 32 is quickly transferred to the juice holder 34 through the discharge port 37a. flows inward.

In addition, the lees receiver has a relatively large amount of lees in the container 32 that can pass through the gap between the lower end of the material input tube 54 and the cut-out 27, such as thin apple peel or fibrous material. Although it is crowded, there is a blocking wall 36 on the upper surface of the upper bottom wall of the stepped portion 35.
is installed vertically, so that the end of the upper bottom wall does not face the rotating water flow in an edge-like manner, and therefore, even relatively large pieces of lees hit the blocking wall 36 and are carried away by the water flow to the lees drain located directly below. The juice receiver is led to the outlet 37a, and the juice receiver is in the section 3.
4 will quickly flow out.

Then, the relatively large lees that flowed into the juice receiver section 34 are finely cut by the blades of the stirring blades 22, and are discharged from the juice outlet 39 together with the juice and lees that have adhered to various parts of the main body case 2. It is discharged to the outside through the take-out valve 40.

When the cleaning of the main body case 2 is completed in this way and the water supply and motor 4 are stopped, the shielding plate 37 is rotated by the spring 38a and automatically returns to the closed position.

Then, if the water supply pipe 64 is locked in the upper position as shown in FIG. 8, juice can be made again.

As described above, according to this juicer, there is no need to remove the lid body 49, the centrifugal separator 25, etc., and the opening and closing of the shielding plate 37 is performed automatically, so almost no manual operation is required. The inside of the main body case 2 can be cleaned instantly, and juice can be made immediately after cleaning.

In addition, the lees receiver forms a partially downward stepped portion 35 on the bottom wall of the container 32 that resists the rotating water flow, and the lower opening of the step serves as the lees discharge port 37a. The cover plate 37 that closes the 37a is reliably opened by the rotating water flow generated by the rotation of the centrifugal separator 25, and the lees in the container 32 is quickly transferred to the lees receiver through the lees outlet 37a to the juice receiver 34. leak.

Furthermore, since a blocking wall 36 is erected on the soil surface of the upper bottom wall of the stepped portion 35, the juice receptacle flows into the portion 34 without being caught on the upper bottom wall end of the relatively large lees, resulting in an excellent A cleaning effect can be obtained.

Note that the shielding plate 37 that closes the lees discharge port is not opened and closed horizontally as in the previous embodiment, but is opened and closed vertically using the upper edge as a pivot as shown in FIG. 9 or 10. Good too.

That is, the upper edge of the shielding plate 77 shown in FIGS. 9 and 10 is attached to the lower end of the upper bottom wall of the stepped portion 35 so as to be rotatable in the vertical direction, and the lower end is provided with a weight 78 and an engaging recess 79. It is being

On the other hand, the recess 7 is provided on the lower surface of the terminal end of the lower bottom wall of the stepped portion 35.
A protrusion 80 is provided which engages with 9.

The shielding plate 77 is always in the closed position due to its own weight including the weight 78, and its recess 79 is engaged with the protrusion 80.

This shielding plate 77 has a recess 79 when making juice.
During cleaning, the lees tray is pushed from the inside by the rotating water flow generated in the container 32, disengaging from the engagement and opening upward. .

In addition, the bottom wall of the container 32 for the lees receiver is not formed in a spiral shape around the entire circumference as in the previous embodiment, but is partially lowered on one side of the stepped portion as shown in FIG. may be formed horizontally.

As explained above based on various embodiments, according to the present invention, the annular lees receiver provided around the centrifugal separation capacity quickly removes the lees in the part (the lees receiver is a container). It is possible to provide an automatic cleaning type juicer that allows the juice to flow to the surrounding area and provides an excellent cleaning effect.
