is provided.

A flange 48 and a guide pin 49 are protruded from the outer peripheral surface of the transparent tube 38, and a flow rate display scale 50 is attached.

Therefore, the brush 41 of this filter cleaning tool 36 is introduced into the main body case 4 through the brush insertion port 1B at a nearly right angle to the inner surface of the filter 11, as shown in FIG.
It comes to closely face the inner surface of the filter 11 of the centrifugal separation cage 10.

Further, a guide pin 49 protruding from the transparent tube 38 is fitted into the guide recess 26, and the filter cleaning tool 36 has a certain inclination due to the engagement between the guide pin 49 and the recess 26, that is, the material input port 17a. It is held at a position crossing above the filter 11, and the amount of movement toward the filter 11 is regulated.

Then, the spout 47 is located above the material input port 17a.

Further, a bellows-shaped elastic cylinder 51 is fitted on the outer periphery of the transparent tube 38 between the flange 48 and the guide pin 49.
By abutting one end of the elastic cylinder 51 against the flange 48 and the other end against the bracket 25, the brush 41 of the cleaning tool 36 is spaced apart from the inner surface of the filter 11.

Note that the transparent tube 38 is connected to a water supply source, for example, a water faucet, via a flexible hose 52.

Therefore, in order to make juice of vegetables, fruits, etc. using this juicer, first pull out the filter cleaning tool 36 from the brush insertion port 18, place a cup or the like below the outlet 31 of the cock device 6, and turn the operating knob 34. Inlet 2

Therefore, when the cock device 6 is opened and the motor 1 is driven to rotate the stirring blades 7 and the centrifugal separation basket 10, a rotating water flow is generated inside the juice receiving section 28 and the lees receiving container 27, and the lees receiving container 27 is rotated. The lees inside is swept away from the notch 29 to the juice receiving part 2B.

Also, relatively coarse lees are finely cut by blades formed on the stirring blades 7 and discharged to the outside through the flow path 32 of the cock device 6.

At this time, the dregs and juice adhering to the inner surface of the material input cylinder 17 are removed by the cleaning water sprayed from the spray port 47.

Also, the resistor 39 inside the transparent tube 38 moves downstream against the spring 40 due to water pressure, and the amount of movement is measured by the display scale 5.
0, it can be visually recognized from the outside.

Therefore, it is possible to fully open the cock device 6 and adjust the water supply flow rate while visually checking the position of the resistor 39 to obtain a water supply flow rate that corresponds to the drainage flow rate.

Further, when the cleaning tool 36 is pushed against the elasticity of the elastic cylinder 51 and the brush 41 is brought into contact with the inner surface of the filter 11, the scum adhering to the filter 11 is quickly peeled off, and the notch groove 46 and the flow path 44a are removed. , 44 b and is washed away by water jetted through the tubes and discharged by centrifugal force.

Moreover, when the pressing force from an external operation is released, the brush 41 is separated from the filter 11 due to the elasticity of the elastic cylinder 51.

As described above based on the embodiments, the cock device of the present invention includes a cylindrical case 30 that is open at one end, has an inlet 29 at the other end, and an outlet 31 on the peripheral wall;

Since the case 30 and the valve body 33 are in contact with each other only at the protrusions 35a and 35b, the contact resistance is small, and therefore the valve body 33 can be easily rotated. .

Note that the present invention is not limited to the embodiments and can be modified in various ways.

For example, the valve body 33 only needs to have elasticity in at least the protrusions 35a, so the protrusions made of an elastic material may be attached to the surface of a hard member.

Further, the operating knob 34 and the valve body 33 may be formed entirely of an elastic material.

Further, at least one annular protrusion 35a is required on both sides of the outlet 31, and the linear protrusion 35b is not necessarily required.

The cocking device of the present invention can be widely applied to other applications than juicers.
