[Industrial applications]

 The present invention relates to an improved technique for a hot and cold water mixing valve with a water purifier.

[0002]

[Prior art]

 In order to equip a hot water mixer with a water purifier, conventionally, a branch pipe with a water shutoff plug is provided on the lateral side of the mixer tap body in a state of communicating with the water flow path of the mixer tap body. Takes the form of connecting the water purifier to.

[0003]

[Problems to be solved by the device]

 However, in such a configuration, the water purifier cartridge overhangs to the lateral side of the mixing stopper main body, and the water purifier cartridge is relatively heavy and has poor stability. It is necessary to take measures, and in addition, the number of parts is increased because the supporting means and the branch pipe with a water stopcock are required, and there is room for improvement in that the cost of the hot and cold water mixer itself is high. The present invention has been made in view of such circumstances, and an object thereof is to make the hot and cold water mixing valve with a water purifier compact and reduce the cost by rational improvement.

The mixing stopper body 1 is formed on the stopper main body 1 and is provided with the water stopcock 2 for opening and closing the raw water outlet passage C, while the upper wall portion of the mixing stopper main body 1 constituting the raw water outlet passage C is formed. Assemble the water purifier 3 into 1a, open the stopcock 2 and take out the raw water from the water channel 14 and take out the raw water for water purification into the channel C, and introduce this into the water purifier 3 to introduce the purified water into the faucet for water purification. I am trying to make it flow out from 9.

As shown in FIG. 1, the water purifier 3 has a lower cover 4 screwed into a mounting hole 7 formed in an upper wall portion 1a constituting the raw water outlet channel C, and a lower cover 4 of the lower cover 4. 4 is composed of an upper cover 5 which is detachably mounted, and a lower end portion of which is a water purifier cartridge 6 which is watertightly mounted to a screwing portion of the lower cover 4. On the other hand, in the water purifier cartridge 6, the lower opening of the outer chamber 6A of the casing 61, which has a double chamber structure with partition walls, serves as the raw water intake port 65, and the lower opening of the inner chamber 6B serves as the purified water intake port. The outer chamber 6A is filled with a first filter 62 such as activated carbon, and the inner chamber 6B is filled with a second filter 63 made of polyethylene hollow fiber membrane or the like. A third filter 66 such as a nonwoven fabric is provided so as to cover the upper and lower portions.

At the portion of the lower wall portion 1b constituting the raw water withdrawing passage C facing the mounting hole 7, the water purification outlet 64 of the cartridge 6 becomes watertight as the water purifier cartridge 6 is attached. A connecting pipe 8 that communicates is provided, and the downwardly projecting portion 81 of the connecting pipe 8 is provided with the water purification faucet 9 rotatably. That is, the base 91 side of the water purification faucet 9 is fitted into the protruding portion 81 of the connecting pipe 8 via a plurality of seal members 92, and the peripheral groove 82 is provided in the outer peripheral portion of the protruding portion 81. A stop pin 93 is inserted into the circumferential groove 82 so that the water purification faucet 9 is rotatable in a watertight manner with respect to the connecting pipe 8.

The mounting structure for the upper wall portion 1a of the lower cover 4 can be modified as shown in FIG. 5, for example. That is, the support pipe 51 with the flange 52 is screwed into the mounting hole 7 formed in the upper wall portion 1a, the lower cover 4 is attached to the support pipe 51, and the lower cover 4 and the support pipe 51 are formed. Modifications such as fitting the nut 53 to the common screw portions 4a and 52a are possible.

FIG. 6 shows another embodiment in which a stand-type hot and cold water mixing tap is applied to the present invention. The water flow on the upstream side of the hot and cold water mixing portion 15 of the hot and cold water mixing tap attached to the deck 10 such as a sink is shown. The raw water withdrawal passage C for purification is branched from the passage 14, and the water stopcock 2 for opening and closing the raw water withdrawal passage C is provided, and the raw water inlet 65 of the water purifier cartridge 6 is provided with the raw water withdrawal flow. In the state of communicating with the channel C, the water purifier cartridge 6 is detachably provided on the upper wall portion 1a constituting the raw water withdrawing channel C, and the lower wall portion 1b constituting the raw water withdrawing channel C is A connection pipe 8 is provided which is connected to the purified water outlet 64 when the water purifier cartridge 6 is attached, and the connection pipe 8 is further provided with a water purification faucet 9.

In FIGS. 5 and 6, members corresponding to the constituent members shown in FIGS. 1 to 4 are designated by the same reference numerals and will be redundantly described.

[Effect of the invention]

 As described above, the hot and cold water mixing tap with a water purifier of the present invention is a hot and cold water mixing tap having a faucet for letting out mixed water, and the raw water extraction flow path for purification is provided from the water flow path upstream of the hot and cold water mixing section. In addition to branching to form the mixing tap body, a water stopcock for opening and closing the raw water extraction flow path to switch the water flow path is provided at the branching position, while the hot water supply pipe and the water supply pipe support both sides of the installation. It is characterized in that the mixing stopper main body with high strength is used as a supporting member, and the water purifier is equipped on the upper wall of the mixing stopper main body itself. That is, (i) a water purifier (water purifier cartridge) is equipped on the upper wall of the mixing tap body itself, (ii) a water purifier is detachably provided on the upper wall, and (iii) a faucet is for mixing water. And two for water purification, and (iv) One water stop is used to switch the water flow path to form a branch, which is compact because there is almost no overhang of the water purifier from the mixing tap body. In addition, the mounting posture of the water purifier can be stabilized without any additional support measures, and the number of parts can be reduced by eliminating the need for support means and a branch pipe with a water stopcock. Since this is achieved, cost reduction can be achieved.
