Abstract

PURPOSE:To certainly perform water-tight seal, by such a simple structure that the raw water port and the purification port of a water purifier are arranged so as to be capable of being changed over when raw water is supplied and respective water passages are held in a water-tight state through packings. CONSTITUTION:When tablewares are washed, a guide pipe 25 is withdrawn into a main body case 1 and a raw water port 30 is opposed to a suction port 7. When raw water is directly supplied in this state, a first packing 32 is contacted with the inner wall of a branched pipe 11 under pressure and raw water from the suction port 7 is prevented from leaking to a rear part opening 9. When purified water is obtained as drinking water, a knob member 5 is drawn out and raw water from the suction port 7 is guided to the rear part opening 9 of the branched pipe 11, a purification filter 45, the purificiation port 31 of the guide pipe 25 and a supply port 18. At this time, a communication passage is perfectly sealed by a second packing 33 and no short-circuit is generated.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a water purifier that uses a purification filter to obtain purified water.

First Prior Art Conventionally, as shown in Japanese Utility Model Application Publication No. 49-41965, for example, a passage dedicated to purified water and a passage dedicated to raw water were formed separately, making the watertight seal for this complicated and the switching mechanism required. It had the disadvantage of being complicated.

(c) Purpose of the Invention Therefore, the present invention has a simple structure that allows switching to use for purified water or raw water, and also ensures a watertight seal.

B) Structure of the Invention The structure of the present invention includes a main body case having an inlet at the rear for communicating with a water faucet and a supply port for supplying raw water or purified water to the outside at the front; It consists of a guide pipe that moves back and forth and communicates with the suction ports 0 and 1, and a purification filter provided on the outer periphery of the guide pipe, and a rear portion of the guide pipe that selectively communicates with the suction ports. A raw water hole is formed in the middle part, a purification hole that communicates with the purification filter is formed in the middle part, and a drainage hole is formed in the front part that constantly communicates with the supply port, and sealing gaskets are wrapped on the upstream and downstream sides of the raw water hole. The suction port and the raw water hole are watertightly communicated when the guide pipe is retracted, and the suction port and the purification filter and the purification hole are watertightly communicated when the guide pipe is pulled out. It is.

@9 Example (1) is a medium-sized 9-shaped purifier main body, and the water faucet (2
)K connection member (3) and vA connection member (31
The main body member (4
) and a knob member (5) disposed at the tip of the main body member (4).

The connecting member (3) has a cylindrical shape with an open side, and when a connecting screw (6) is formed on the inner peripheral surface near the opening, a film is deposited on the faucet (2) on the top surface and the raw water is sucked. Mouth (7
) is formed. The mounting part (
8) projects into the interior of the connecting member (3) and forms a middle 9 branch pipe having a rear opening (9) and a front opening 1() at its lower end. A connecting groove 03 that is continuous with the suction port (7) is formed on the inner peripheral surface of the branch pipe a11.

The main body member (4) has a cylindrical shape with a diameter of 9 mm, and has a mounting screw A3 screwed onto the connecting screw (6) formed on the outer periphery of the rear part, and a ring-shaped glue packing A41 attached to the front part. is the tightening part (1G
is formed protrudingly.

The knob member (5) is molded from synthetic resin such as AES and has a chrome-plated surface, and has a connection opening (
lη and a supply port U at the lower front end.

Inside thereof, an abbreviated-shaped discharge pipe portion aCt is integrally formed so as to be double-layered as a whole. An arcuate bulge part (2) is integrally formed in the lower part of the inner wall of the discharge pipe part α9 in the longitudinal direction.

The surface of the bulging portion (4) is made into a flat curved surface with no inclination by utilizing its surface in the longitudinal direction of the front and back, and the other inner wall of the discharge pipe portion 0 widens and slopes toward the connection opening aη. Opposed screw holes t2n@ are formed at the lower end of the knob member (5) and the lower surface of the discharge pipe section a9, respectively, and a rectifier &(c) is installed inside the supply opening. .

(c) is a guide pipe with a straight 9-1 shape and a discharge hole 121t formed at the tip, and is screwed clnV so as to match the bulge (a) formed in the discharge pipe section 4 of the knob member (5).
C is inserted and fixed. The guide pipe (c) is supported and slid by the tightening part u61 and the branch pipe aD, and has six raw water holes drilled in the circumferential direction at the rear part thereof, which are connected to the suction port (7) J1b. Two purification holes C311 are bored in the middle part. The total opening area of the purification holes 011 is smaller than the total opening area between the raw water holes. A first packing 63 and a second packing 63 are fixed on the upstream and downstream sides of the raw water hole (to) and are in watertight pressure contact with the inner wall of the branch pipe aυ. Said guide pipe C2!19
On the distal end side of the discharge pipe part (11), a packing part (1143) which is watertightly pressed against the discharge pipe part (11) is fixed, and a locking groove is formed around the outer periphery near the upstream side thereof.

On the downstream side of the purification hole Gll, there are two locking pins C @ for preventing the guide pipe (C) from being removed from the main body case (11).
I'm counting the pieces.

(to) is a cylindrical connecting member that is screwed and fixed to the tightening part (161) of the main body member (4);
and three hook portions (4a) are integrally formed. The stepped portion f40 is normally covered with a knob member (5), and the hook portion θυ can be freely engaged and detached from the locking groove Chi of the guide pipe Q31. It is said that

(4 is a third packing that is inserted into the guide pipe (c) so as to be located between the connecting member (c) and the tightening part cIe of the main body member (4), and the stopper member (43G13
It is held in place. This stopper part (the 6th floor is on the 4th floor)
It moves between the connection member (to) and the locking bottle country together with the packing (4z).
prevents raw water from leaking into the knob member (5).

1 (4) is a cylindrical purification filter that is inserted into the guide pipe c!S.
It is filled with activated carbon to be removed, and elastic disks f4 (91Q) having elasticity are fixed to both ends thereof.

According to this configuration, when the water is not used for drinking but only for washing tableware, the internal vibrator 4 is drawn into the main body case (1) as shown in Figure 1, and the water is connected between the raw water hole and the inlet (
71 to face each other. At this time, the faucet (2)
The raw water supplied from the inlet (7), the communication groove (121,
This is because the raw water passes between the holes, the inside of the guide pipe (c), and the supply port a barrel, and is directly supplied to the outside. When this raw water is directly supplied,! Since the 51 gasket 0 is pressed against the inner wall of the branch pipe 1111, the raw water from the P inlet (7) will not leak into the rear opening (9) of the Choki vibrator 011. If you don't have this instant 1 patchkin 04, 1
Spring water t: Fe part opening (9) → purification filter (・1 gu →
This has the disadvantage that the purification hole Gll leaks, and purified water is always obtained even when purified water is not needed, and the purification filter (4) is rapidly worn out, resulting in a shortened service life.

Further, when obtaining purified water as a beverage, it can be achieved by pulling out the knob member (5) as shown in FIG. Note that the guide pipe 4 is prevented from popping out with a locking bottle holder. The raw water from the inlet (7) goes to the rear opening (9) of the branch pipe 0υ → purification filter 0! It passes through the purification hole C311 of the guide pipe (c) → the back part of the guide pipe (2) → the supply port a second, and is converted into purified water in the purification filter.

When obtaining this purified water, if there is no W42 gasket (c), the raw water from the rear opening (9) will pass through the guide pipe (c) rather than passing through the entire purification filter (49 and reaching the purification hole C31). More water flows between the raw water holes through the gap with the branch pipe αB, resulting in a short circuit, reaching the raw water hole (7) before being sufficiently purified by the purification filter (4c9), and not being purified. Raw water will be supplied outside.

Even if a large amount of raw water is supplied by opening the water supply mark more than necessary when obtaining purified water, the opening area of the purification holes C313 is smaller than the area between the raw water holes.

This purification hole C311 controls the flow of purified water at a certain point so that the raw water can always pass through the purification filter 09 in an optimal state.

Usually, the hook part of the connection member (to) (41J is the locking groove C39
Because it is locked to the main body case (1) when raw water is supplied.
The knob member (5) is not pulled forward even when the switch 1 is shaken from side to side, so that the purified water is not unnecessarily supplied.

Moreover, the knob member (5) is placed inside the discharge pipe portion α.
Because it has a double structure of synthetic resin so that it has g,
Even if you connect it to a water heater to supply hot water.

There is no risk of getting burned at the knob (51).

Furthermore, as shown in FIG. 9A2, when purified water is supplied, the stepped portion 410 of the connecting member C is exposed, so that the user can visually see that purified water is being supplied.

As shown in Fig. 1, when raw water is supplied, the space in which the purification filter (49 is installed) is completely sealed by the second packing (g) and the third packing (1). (c) Even if the raw water flowing inside tries to leak from the purification hole C311 into the 9-part area, the purification filter (raw water has already soaked into the 4 parts), so as a result, the inside of this 9-part part is This means that it is full of purified water, so even if some raw water may flow in from the purification hole GD, it is sent to the supply port ttS without ever flowing in.

(f) Effect of invention This is because the present invention is constructed as described above.

When raw water is supplied, t! ! J1 packing and 2nd packing prevent the raw water from leaking to the purification filter side and send it all to the guide pipe, and when supplying purified water, the 2nd packing prevents the raw water from short circuiting to the raw water hole. This allows raw water to reliably pass through the purification filter.
