Description

[Detailed Description of the Invention] The present invention relates to a filter cleaning tool for a juicer that allows the flow rate of cleaning water introduced into the main body case of the juicer to be easily checked.

Generally, a juicer houses a centrifugal separator in its main case and rotates it at high speed, cutting the vegetables, fruits, and other materials fed into the separator into fine pieces using a cutter installed on the inner bottom of the separator. The juice that has passed through the filter on the separation wall is allowed to flow out from the juice outlet.

However, with conventional juicers of this type, each time the juicer is used, the lid that closes the upper opening of the main body case is removed, the centrifugal separation capacity is also taken out, and the inner surface of the main body case, filter, etc. are cleaned. The disadvantage is that it has to be reassembled, which requires a lot of time and effort for cleaning and assembling after use.

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

This is done by filling water in the main case and rotating the centrifugal separation function to generate a rotating water flow inside the main case, and this water flow removes juice and dregs that adhere to the inner surface of the main case through a juice outlet or a separate outlet. It is configured to be discharged to the outside through a drain port.

However, it is difficult to remove dregs that have adhered to the inner surface of the filter using only the rotating water stream, and a large amount of water is required. It has been proposed to insert a brush and bring it into contact with the inner surface of the filter, supply water into the main body case, and rotate the centrifugal separator to remove the dregs adhering to the inner surface of the filter.

By the way, one possible way to supply water in this case is to introduce the tip of a flexible hose connected to a water faucet into the material input port or a separately provided water supply port, but depending on the drainage flow rate, It is difficult to adjust the water supply flow rate, and if the water supply flow rate is too high, water will overflow from the brush insertion port or material input port, and if it is too low, the desired cleaning cannot be performed.

The present invention was developed to solve these problems, and its purpose is to make it possible to visually check at a glance the amount of water being supplied into the juicer's main case, and to easily obtain the appropriate flow rate. An object of the present invention is to provide a filter cleaning tool for a juicer.

Furthermore, an L-shaped stopper 46 is fixed to the connecting member 39 to limit the range of rotation of the brush 40.

Therefore, in order to make juice of vegetables, fruits, etc. using this juicer, first place a tap 47 below the outlet 33 of the cock 29, turn the operating knob 32, and turn the valve body 3.
1, the opening 31a of the water supply nozzle 3B is aligned with the discharge port, and the cleaning tool 37 is pulled up as shown in FIG. The lower opening of the nozzle 38 is aligned with the upper through hole 18a.

Then, the brush 40 separates from the filter 11, comes into contact with the guide surface 19a, and is held in a substantially vertical state.

Therefore, the motor 1 is driven to generate the stirring blade 7 and the centrifugal separation capacity 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 receiver section 24, and is discharged from the outflow pipe 6 to the tap 47.
flow inward.

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

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

That is, the filter cleaning tool 37 is lowered, the upper annular groove 44a is locked with the locking edge 22C of the cap 22, and the lower opening of the water supply nozzle 38 is aligned with the lower through hole 18b.

Then, the brush 40 comes into contact with the inner surface of the filter 11, so in this state, position the outlet 33 of the cock 29 above the sink, and connect the upper end of the transparent pipe 41 to the water faucet via the flexible hose 4B. , supply water.

Then, the resistor 42 moves in the direction of the nozzle 38 against the spring 43 due to the pressure of the water flow, a flow path is formed around the resistor 42, and cleaning water is supplied into the main body case 4 through the nozzle 3B. be done.

At this time, a part of the cleaning water is injected into the material input cylinder 15 through the through hole 18b to clean the inside of the material input cylinder 15, and the other part is injected along the inner surface of the lid body 5 to clean the inside of the material input cylinder 15. Clean the inside,
The lees receiver flows down into the container 23.

In this state, when the motor 1 is driven to rotate the stirring blades 7 and the centrifugal separator 10 at high speed, a rotating water flow is generated inside the main body case 4.

The lees receiver is the step portion 25 formed in the container 23 and the blocking wall 2B is the lees receiver is the rotating water flow (counterclockwise) generated inside the container 23.
Since the lees receiver acts as a resistor against the water, the rotating water flow inside the container 23 is rebounded by the stepped portion 25 and the blocking wall 28, and the juice receiver flows out into the portion 24 through the cutout portion 26.

Therefore, the lees in the lees receiver container 23 quickly flows out through the notch 26 to the juice receiver 24, and the juice outlet pipe 6
is discharged to the outside.

Note that 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 on the stirring blades 7, so the outflow pipe 6 The lees that are discharged more often do not contain large particles,
Therefore, it can be disposed of directly into the drain, eliminating the hassle of garbage disposal.

Also, the dregs adhering to the inner surface of the filter 11 are removed by a brush 32.
and is discharged to the outside together with the dregs and juice that have adhered everywhere inside the main body case 4.

By the way, when cleaning the inside of the main body case 4 as described above, it is necessary to adjust the water supply flow rate to be approximately the same as the drainage flow rate discharged from the juice outlet 6, but as the water supply flow rate increases, As the resistor 42 lowers, the water supply flow rate can be checked at a glance, and while the position of the resistor 42 is visually checked from the outside, the opening degree of the water valve can be adjusted so that the position falls within a predetermined range. By adjusting
Appropriate flow rate can be easily obtained.

Note that the present invention is not necessarily limited to the configuration of the embodiment.

For example, the transparent tube 41 does not need to be entirely transparent, but only needs to be partially transparent to the extent that the position of the resistor 42 can be visually recognized from the outside.
