Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a water purifier for treating water such as tap water for active purification.

[0002]

[Prior art]

 Conventionally, a water purifier having a structure shown in FIG. 3 is generally known as a water purifier used at home. In this conventional water purifier, an upper lid 3 is provided at the upper end of the storage cylinder 2, a bottom member 4 is provided at the lower end, and a water inlet 5 communicating with the storage cylinder 2 is provided on the side surface of the bottom member 4 and the upper cover 3 is provided. A water reforming activator is contained in a filling cylinder 9 that accommodates a housing 1 having a water supply pipe 6 at the center of the housing 1 and an inner wall surface of the housing cylinder 2 so that the space 7 can be freely inserted into and taken out of the housing cylinder 2. 10A, activated carbon 10B, coral sand 10C, natural ion calcium 10D, and other treatment agents are filled in layers, and a cartridge filter 8 loaded in the housing 1 is provided. Reference numeral 11 designates an inflow hole 12, and a lid plate capped on the upper end of the filling cylinder 9; 13 a discharge pipe penetrating the bottom plate 14 and the lid plate 11 of the filling cylinder 9 and standing in the center of the cartridge filter 8; Reference numeral 15 is a through hole provided on the lower end side of the discharge pipe 13, 16 is a filter laid near the bottom of the filling cylinder 9, 16A is a filter placed on the upper end surface of the water treatment agent 10, and 17 is a bottom member 4. The formed drainage hole, 18 is a closing plug attached to the drainage hole 17, 19 is a connecting plug attached to the water inlet 5, and 20 is a housing, which is fitted in the upper end of the discharge pipe 13. A packing member 21 provided on the upper side of the upper lid 3 is provided for sealing the portion.

The conventional water purifier is configured as described above, and is used by connecting the connection plug 19 to a tap (not shown) of a water supply. When the faucet cock is opened, the water enters the water inlet 5 Is introduced into the housing 1, rises through the gap portion 7, flows into the cartridge filter 8 from the inflow hole 12 of the cover plate 11, passes through the water treatment agent 10, is purified, and passes through the filter 16. The water enters the discharge pipe 13 through the through hole 15, rises up the pipe 13 and is supplied from the water supply port 6. As a result, tap water can be treated with any water treatment agent and used as drinking water.

By the way, in this kind of water purifier, when the cock of the faucet or the like is closed, water remains in the running water channel in the housing. Therefore, when the cock is opened again, the water remains in the housing. The existing water will be delivered as drinking water. Therefore, it is sanitary to reduce the residual amount of water in the housing when the cock is closed, that is, when the water is not used.

However, in the conventional water purifier described above, the entire space 22 formed between the storage cylinder 2 and the filling cylinder 9 and the space 22 formed between the upper lid 3 and the upper surface of the cartridge filter 8 when not in use. Since it becomes a reservoir of water, there is a problem that a considerable amount of water remains in the housing.

[0006]

[Problems to be solved by the device]

 The present invention has been made in view of the above circumstances, and an object thereof is to provide a water purifier that can reduce the residual amount of water in the housing when not in use.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, a water purifier according to the present invention includes a housing in which an upper end of a container is closed by an upper lid and a lower end is closed by a bottom member, and a lower end of a pipe is fixed by being embedded in a bottom member. A discharge pipe is formed by projecting the upper end of the body from the upper lid, and a discharge pipe erected in the center of the housing and a central pipe body is installed vertically in the center of the filling cylinder whose upper and lower ends are closed. A cartridge filter that is filled with the agent and that is stored in and taken out from the housing cylinder of the housing and is housed automatically. A water inlet that communicates with the inside of the housing cylinder is formed on the side surface of the bottom member. Forms a flowing water passage between the central pipe body and the pipe body, fits the central pipe body into the pipe body, and hermetically seals the bottom peripheral edge of the filling cylinder to the inner wall surface of the lower end of the containing cylinder. It is contained in the container, An outlet hole is formed at the upper end of the center pipe body to connect the upper end of the filling cylinder to the running water passage, and the bottom of the cartridge filter is filled with water introduced from the water inlet into the storage cylinder. An inflow hole for receiving is formed, and a through hole is formed at a lower end portion of the discharge pipe to connect the flowing water passage and the pipe body.

[0008]

[Action]

 According to the present invention, the cartridge filter is accommodated by hermetically sealing the bottom peripheral edge of the filling cylinder to the inner wall surface of the lower end of the housing cylinder of the housing, so that the cartridge filter is introduced from the water inlet to the bottom of the housing. Water flows directly into the filling cylinder from the inflow hole at the bottom of the cartridge filter, passes through the water treatment agent in the cylinder, is processed, and flows out from the upper end in the filling cylinder to the running water passageway through the outflow hole. Water is supplied from the through hole through the pipe. As described above, according to the present invention, the space formed between the containing cylinder and the filling cylinder and between the upper lid and the upper surface of the cartridge filter is not a flowing water channel, and water does not flow in. . Therefore, the residual amount of water in the housing when not in use is small.
