[0004]

[Problems to be solved by the device]

 However, the above-mentioned conventional water purifier has the following problems.

That is, in the conventional water purifier, since the water purifier main body 2 is provided separately from the body 1, not only a large installation space is required around the water tank such as a sink, but also in the water purifier main body 2. Replacing the provided filter unit was also very inconvenient because the water purifier body had to be disassembled into many parts.

The present invention has been made in view of such circumstances, and the water purifier main body can be easily attached to and detached from the body, and does not require a large installation space around a water tank such as a sink. The purpose is to provide.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has the following configuration.

That is, the present invention provides a faucet direct connection type water purifier in which a water purifier body for purifying raw water is integrally attached to a body for connecting a faucet, wherein (A) the body is the raw water from the faucet. A raw water inlet for receiving the raw water, a raw water feed port to the water purifier body, a raw water outlet, and a flow passage switching valve for switching the raw water to the water feed port or the flow passage to the raw water outlet, (B) the water purifier body, (C) the raw water inlet of the body and the raw water of the main body of the water purifier, having a raw water inlet for engaging the water outlet of the body, a filter unit for purifying the raw water, and a purified water outlet for supplying purified water. All of the water inlets project laterally, the water inlet is formed into a tubular body, and the raw water inlet has an inner diameter into which the tubular body of the water inlet is mounted, (D) Sending raw water from the body Between the mouth and the raw water inlet of the water purifier main body, wherein the connecting means for connecting said purifier body detachably attached to the body is provided.

In this case, it is preferable that the connecting means is a means for pressing and fixing the raw water feed port of the body and the raw water inlet port of the water purifier body in a direction in which they approach each other. Further, when the body is attached to a swing arm type faucet, it is convenient because a wide space around a water tank such as a sink can be used.

[0010]

[Action]

 According to the water purifier of the present invention, when the water purifier main body is attached to the body, the raw water inlet protruding from the water purifier main body is attached to the water supply port of the body formed in the tubular body, and both are attached. Connected by connecting means. In addition, when removing the water purifier body, the water purifier body is pulled out from the body after the connection means is released.

[0011]

DETAILED DESCRIPTION OF THE INVENTION A preferred embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a vertical cross-sectional view of a state in which a flow path switching valve is set so as to guide raw water supplied from a faucet to a water supply port to a water purifier body, and FIG. 2 is supplied from a faucet. It is a partial longitudinal cross-sectional view of the state where the flow path switching valve is set so as to guide the raw water to the raw water outlet.

This water purifier is of a faucet direct connection type in which a water purifier body 2 is integrally assembled to a body 1, and in the figure, the case is shown in which it is mounted on a swing arm type faucet 3. A raw water inlet 4 is provided on the upper portion of the body 1, and the faucet 3 is connected to the raw water inlet 4 via a nut 5a. A raw water inlet 6 is provided at the lower part of the body 1, and a foamer 7 is attached in the figure. Further, as shown in FIG. 1, a water supply port 8 is provided on the side of the body 1 inside a cylindrical body 8a protruding laterally. On the other hand, a raw water inlet 19a protruding laterally from the water purifier body 2 in the direction opposite to the body 1 is provided, and the raw water inlet 19a has an inner diameter sufficient to surround the tubular body 8a of the body 1. Have Further, 5c is a mounting member of the elastic ring 5d fixed to the outer peripheral surface of the tubular body 8a by screwing, and by screwing the nut 5b into the screw 14a formed on the outer peripheral surface of the base 14, The cylindrical body 8a of the body 1 is inserted into the raw water inlet 19a on the main body 2 side of the water purifier, and is fixed to the water outlet 8 The surface (contact surface) of the mounting member 5c and the end surface 19b of the raw water inlet 19a With the (abutting surface) abutting against each other, the mounting member 5c of the body 1 and the end surface 19b of the raw water inlet 19a are brought into surface contact with water honey in a direction approaching each other via the elastic ring 5d, This is to prevent the raw water sent from the water supply port 8 from leaking to the outside. That is, the nut 5b, the mounting member 5c, the elastic ring 5d and the screw 14a serve as a connecting means between the body 1 and the water purifier body 2 and prevent water leakage from the raw water sent from the water supply port 8 to the outside. It is also a means.

Inside the body 1, a state in which the raw water inlet 4 communicates only with the water supply port 8 by lateral slide (see FIG. 1) and a state in which the raw water inlet 4 communicates only with the raw water outlet 6 (see FIG. 2) A slide type flow path switching valve 9 that can be switched between and is incorporated. The sliding operation of the flow path switching valve 9 is set at the stroke end by pushing and pulling the knob 10 attached to the outer end of the valve.

Inside the flow path switching valve 9, there is provided a bypass path 13 for connecting the water supply port 8 and the raw water outlet 6, and in the middle of this bypass flow path 13, an internal spring 11 is provided. A safety valve 12 biased in a closed state is incorporated.

The water purifier main body 2 includes a base 14 connected to the body 1, a filter unit 15 that is attached to and detached from the base 14, and a cap 16 that houses the filter unit 15. The filter unit 15 includes a primary filter 17 containing antibacterial activated carbon as a main component and a secondary filter 18 including a bundle of hollow fiber membranes having ultrafine pores. The raw water sent from the water supply port 8 is guided to the primary filter 17 through the introduction port 19 and the stop valve 20, and here, the chlorine, organic substances and the like are removed. The raw water that has passed through the primary filter 17 is further supplied to a secondary filter 18, where fine impurities such as bacteria, iron rust, mold, and nigiri are removed, so that purified water is purified water outlet 21. Spilled from.

Next, the operation of the safety valve 12 of this embodiment will be described with reference to FIG.

FIG. 3 is a partial cross-sectional view showing the periphery of the flow path switching valve 9 in an enlarged manner.

When the filters 17 and 18 in the water purifier body 2 are clogged, the pressure in the water channel on the side connected to the water purifier body 2 gradually increases. When this water pressure becomes higher than the biasing force of the internal spring 11 that biases the safety valve 12 to the closed state, the safety valve 12 is displaced rightward in the figure. As a result, the raw water taken in from the raw water inlet 4 flows through the bypass passage 13 as shown by the arrow in the figure, and is discharged from the raw water outlet 6.

[0020]

EFFECT OF THE INVENTION According to the water purifier of the present invention, the body of the water purifier can be attached to or removed from the body by the raw water inlet protruding from the body of the water purifier at the water supply port of the body formed in the cylindrical body. It is very easy to attach and detach the body of the water purifier and the body, since after connecting and disconnecting, both members are connected or disconnected by the connecting means. Further, in the water purifier of the present invention, since the water purifier main body is integrally assembled to the body, the entire water purifier is compact and does not require a large installation space around a water tank such as a sink.
