2. Description of the Related Art In general, a faucet installed on a washing place side of a bathroom has a shower hose extending from the faucet main body, a shower head connected to the tip thereof, and based on an operation of an operation section of the faucet main body. Water is guided from the faucet body to the shower head through the shower hose, and the shower water can be discharged therefrom.

[0003] In this type of faucet, there is a problem that residual water remains in the shower hose after use of the shower. Particularly, when the shower is not used for a long time until the next use, bacteria grow in the residual water. There was a problem that there was a risk of being unsanitary.

When the temperature of the bathroom becomes high due to steam or the like, there is a possibility that hot water may flow out of the shower head. To prevent this, it has been proposed to provide a water faucet body with a water drainage mechanism for draining residual water in the shower hose.

[0005]

However, when the faucet body is provided with a drainage mechanism as described above, the water in the shower hose can be drained to some extent, but the remaining water in the slackened portion of the shower hose must be drained. However, if residual water remains in the same area for a long period of time, there is a problem that the problem of bacterial generation or growth there cannot be solved.

Although the above description has been made by taking the shower hose as an example, this problem is a problem that can commonly occur in a hose that guides the water sent from the water supply section toward the water discharge section at the tip.

[0007]

The invention of the present application has been made to solve such a problem. According to the first aspect of the present invention, there is provided a hose which guides water sent from a water supply section toward a water discharge section at a distal end, and after the supply of water from the water supply section is stopped, the residual water inside is supplied to a base end side. And a squeezing means for squeezing water from the water discharge portion at the front end.

According to a second aspect of the present invention, in the first aspect, the hose is a shower hose that connects a faucet main body and a shower head in a faucet with a shower.

According to a third aspect of the present invention, in any one of the first and second aspects, the water flow pipe in the hose is made of an elastic material and has a flat cross section in advance and has a thick wall thickness from the proximal end to the distal end. From the base end side to the tip end side by the elastic restoring force of itself after stopping the water supply. The remaining water is squeezed toward the water discharge section on the distal end side, and the elasticity and shape of the flow pipe constitute the squeezing means.

According to a fourth aspect of the present invention, in the third aspect, the hose has a double pipe structure of an inner pipe and an outer pipe, and the inner pipe is used as the flow pipe for the water. Features.

A fifth aspect of the present invention is characterized in that, in the fourth aspect, an air hole through which air enters and exits from the space between the inner pipe and the outer pipe is provided.

[0012]

As described above, the hose according to the first aspect of the present invention squeezes the remaining water inside from the base end toward the front end after the water supply from the water supply section is stopped, and discharges the water from the water discharge section at the front end. In this hose, after the water supply is stopped, the squeezing means squeezes the remaining water inside and discharges it from the water discharge section at the tip, so that no bacteria are generated in the remaining water portion remaining inside. The problem of multiplication and unsanitation can be solved.

As described above, especially in a faucet with a shower installed in a bathroom or the like, the shower hose is usually in a slack state, and a part thereof is located below the faucet main body. The present invention is particularly effective when applied to a shower hose in such a faucet with a shower (claim 2).

As described above, when the present invention is applied to a shower hose in a faucet with a shower, since residual water can be prevented from being generated in the shower hose after use of the shower, the generation or proliferation of bacteria in the residual water portion can be prevented. In addition to this, it is possible to simultaneously solve the problem that, for example, when the temperature of the bathroom becomes high due to steam or the like, the remaining water may become hot water and may come out of the shower head.

According to a third aspect of the present invention, the water flow pipe of the hose is formed of an elastic material so as to have a flat cross section and a thickness gradually increasing from the base end to the tip end. In the case of water supply, the flow pipe expands due to the water supply pressure and smoothly guides the water flow, and after water supply is stopped, its elastic restoring force causes its cross-sectional shape from the base end to the tip side. Has a flattened shape, and the shape change causes the residual water to be squeezed out toward the water discharge portion on the tip side.

That is, in the hose according to the third aspect, the squeezing means is constituted by the elastic force and the shape of the flow pipe. When the hose is constituted as described above, the squeezing mechanism having a complicated structure is required. Even if it is not provided, the residual water inside the hose can be satisfactorily discharged after stopping the water supply.

According to a fourth aspect of the present invention, the hose has a double pipe structure of an inner pipe and an outer pipe, and the inner pipe is formed as the flow pipe of the water, that is, the inner pipe is formed from the base end to the distal end. The hose is formed from a thick wall to a thin wall and has a flattened cross-section toward the side. In the case of this hose, the outer pipe wraps the inner pipe which is usually in a flat state, so that it has a good appearance.

According to a fifth aspect of the present invention, there is provided a hose having a double-pipe structure of the inner pipe and the outer pipe, wherein an air hole for letting air in and out of a space between the inner pipe and the outer pipe is provided. By doing so, the inner pipe can be smoothly expanded or contracted, and the water can be satisfactorily guided for water flow and drained after water supply is stopped.

On the other hand, the distal end side is connected to the shower head 24 by a connection tool 36. Reference numeral 34 denotes an air hole for letting air in and out of the space between the outer tube 28 and the inner tube 30 in the shower hose 22.

The inner pipe 30 serves as a flow pipe for directly guiding the flow of water, and the outer pipe 28 serves as a protective pipe or a makeup pipe for the inner pipe 30 and has flexibility and a predetermined radius. It has a rigidity and is not easily crushed. On the other hand, the inner tube 30 is made of an elastic material such as rubber,
In a free state, it is formed into a flat cross section.

The inner tube 30 has a distal end inserted into the inside of the shower head 24 and is connected to a water discharge section 38 at the distal end of the shower head 24. Thus, the inner tube 30
As shown in FIG. 3, the wall thickness is large at the base end on the faucet main body 18 side, and the thickness is continuously reduced from the base end to the front end on the water discharge section 38 side.

In this embodiment, when the switching handle 27 of the faucet main body 18 is switched to the shower water discharge side, the mixed water is sent out from the faucet main body 18 to the shower hose 22, and the water discharge part 38 at the tip of the shower head 24 is discharged. Is spouted from the shower. At this time, the inner pipe 30 of the shower hose 22 is expanded in a circular cross section by the water supply pressure, and the mixed water from the faucet main body 18 is smoothly guided and guided to the shower head 24.

On the other hand, when the shower water is stopped by operating the switching handle 27, the water supply pressure does not act on the inner pipe 30, so that the inner pipe 30 contracts and deforms into a flat cross section based on its own elastic force. At this time, since the thickness of the inner tube 30 continuously changes from thick to thin from the proximal end to the distal end, the inner tube 30 moves from the proximal end to the distal end as shown in FIG. Continuously shrinks toward the inner tube 3
The water remaining in 0 is squeezed from the base end side toward the front end side, and the water is discharged from the water discharging section 38 to the outside.

As described above, in the shower hose 22 of the present embodiment, the remaining water in the hose is squeezed out of the hose after the water supply is stopped and discharged from the water discharging portion 38 at the tip. Conventional problems such as unsanitation can be solved. Further, when the temperature of the bathroom becomes high due to steam or the like, the problem that the residual water may become hot water and come out of the shower head 24 can be solved at the same time.

Further, in the shower hose 22 of this embodiment, since the squeezing means is constituted by the elastic force and the shape of the inner tube 30, it is not necessary to provide an squeezing mechanism having a complicated structure. Further, in the shower hose 22 of the present embodiment, since the air hole 34 for allowing air to flow in and out of the space between the inner pipe 30 and the outer pipe 28 is provided, the inner pipe 30 can be smoothly expanded or contracted, and as a result, it is possible to improve the performance. It is possible to perform a water distribution guide and a water draining operation after water supply is stopped.

Although the above embodiment is an example in which the present invention is applied to a shower hose in a faucet with a shower installed in a bathroom, the present invention can be applied to a hose for other uses. 4 and 5 show one example.
