Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to kitchen equipment used as water supply equipment such as sinks.

[Conventional technology]

2. Description of the Related Art Conventionally, single faucets installed in sinks, mixed faucets for hot and cold water, and the like have been used in which the water spouting portion can be pulled out and used from the faucet body.

As such a device, for example,
Some are described in Publication No. 16682. This is a hand spray type spout head that can be taken in and out of the faucet body, and a hose is arranged to connect the spout head to a water or hot water source. The spout head can be used like a normal faucet while attached to the faucet body, or it can be taken out and used for washing dishes, etc., depending on the purpose.

[Problem that the invention attempts to solve]

By the way, when the spout head is pulled out from the faucet main body and used, the hose is also pulled out at the same time, and water adheres to this hose during washing operations. When the spout head is returned to the faucet body after work, water remains attached to the hose. On the other hand, since the lower part of the faucet main body has a hose insertion port open for the movement of the hose, water adhering to the hose will flow along the surface of the hose and reach the sink at the lower part.

In this way, when the spout head is pulled out and used, it is inevitable that the inside of the sink will get wet from the water that adheres to it. In this case, since the lower part of the sink is used for storing items, there is a problem in that the stored tableware and utensils get wet. In particular, when food is stored, internal humidity increases, which promotes spoilage, which is also unfavorable from a sanitary perspective.

This invention was devised in view of these problems, and it prevents the water attached to the hose from leaking into the sink even when the spout head is pulled out and used, and also has a gasket that seals the hose. The purpose is to reduce the resistance caused by the gasket, thereby increasing usability and improving the durability of the gasket.

[Means and actions for solving problems]

In order to achieve the above object, the present invention includes a sink forming a sink and a water supply device fixed to the sink, and a spout head is detachably supported in a cylindrical holder provided in the main body of the water supply device. A hose hanging below the main body is connected to the base end of the spout head, a gasket that tightly contacts the circumferential surface of the hose is arranged in the holder, and a water drain hole is provided at a position closer to the tip of the holder than the gasket. The gasket includes a mounting seat held on the inner periphery of the holder, a hose support portion that closely contacts the outer peripheral surface of the hose, and a space between the mounting seat and the hose support portion. and a connection part, the hose support part has a substantially circular cross section with a curved surface in close contact with the hose, and the connection part has a wall thickness in the axial direction of each of the fixed seat and the hose support part. It is characterized by being small.

With this structure, when storing the hose, the packing wipes off water droplets adhering to the circumferential surface of the hose and prevents them from flowing downward, and the wiped water droplets are discharged from the drain hole to the sink side. Also,
Since the gasket has a thin connection part, the hose support part is easily deformed, and since the hose support part has a circular cross section, it reduces resistance when moving the hose both in and out.

〔Example〕

Hereinafter, the present invention will be specifically described based on embodiments shown in the drawings.

FIG. 1 is a longitudinal sectional view of the kitchen device according to the present invention, FIG. 2 is a partial front view of the water supply device, and FIG. 3 is a perspective view of the water supply device when it is placed in a sink.

In the figure, the kitchen device of the present invention is composed of a sink B equipped with a sink A, and a water supply device C placed on the sink B.

The water supply device C includes a main body 1 fixed through the upper surface of the sink B, and a spout head 3 connected to a valve part provided in the main body 1 through a hose 2.
It is equipped with The spout head 3 is a hand spray type that can spout water while fixed to the main body 1, or can be pulled out from the main body 1 and held in the hand to perform washing work.

A cylindrical portion 4 is opened at the lower end of the main body 1 and communicates with a storage cabinet D at the bottom of the sink B.
The water supply pipe 5 and the hot water supply pipe 6 are connected by inserting the water supply pipe 5 and the hot water supply pipe 6.
These water supply pipes 5 and hot water supply pipes 6 are connected to a valve unit 7 arranged on the upper side of the main body 1, and the mixing ratio and flow rate of the hot water and water are adjusted by operating a single lever type handle 8, and the hose 2 The mixed water is supplied to the spout head 3 from the spout head 3. The valve unit 7 is
It has a structure in which two ceramic valve plates 9 and 10 are arranged one over the other inside, and the upper valve plate 10 is linked to the handle 8. Then, by operating the handle 8, the matching ratio of the holes 11 and 12 formed in the valve plates 9 and 10, respectively, can be changed by moving the valve plate 10, thereby mixing hot water and water. The hot water and water thus mixed are discharged into a supply pipe 13 connected to the valve unit 7, and supplied to the spout head 3 through a hose 2 connected to the lower end of this supply pipe 13.

Furthermore, a cylindrical holder 20 for detachably supporting the spout head 3 is formed in the main body 1, and a synthetic resin sleeve 21 is inserted and fixed into the holder 20. Guides 22 and 23 having an annular cross section are formed on the inner periphery of the sleeve 21 to guide the outer periphery of the hose 2, and these guides 22 and 23
A packing 24 that closely contacts the outer peripheral surface of the hose 2 is arranged between them. A cylindrical drain piece 25 fixed to the holder 20 and the sleeve 21 is disposed at a position on the distal side of the guide 22 so as to face downward, and the drain piece 25 is used as a drain hole.

FIGS. 4a and 4b are a perspective view and a vertical cross-sectional view of the packing 24, in which a thick mounting seat 24a is formed on the outer periphery,
A hose support portion 24b having a substantially circular cross section is provided at the inner peripheral portion through which the hose 2 is inserted and comes into contact. Furthermore,
These mounting seats 24a and hose support portion 24b
A thin connecting portion 24c is integrally formed therebetween.

With such a cross-sectional shape of the packing 24, when the hose 2 moves, the hose support portion 24b can easily deform in the direction of movement of the hose 2. That is,
Since the connecting portion 24c is thin, this connecting portion 24c
The portion is easily elastically deformed so as to be inclined in the moving direction of the hose 2, and the hose 2 can be smoothly inserted and removed without chattering vibrations or the like. In addition, since the hose support portion 24a has a circular cross section with a curved contact surface with the circumferential surface of the hose 2, its posture changes so as to follow the circumferential surface of the hose 2, whether the hose 2 is taken out or stored. . Therefore, in addition to the connection part 24c being easily deformed, the hose support part 24b does not undergo unreasonable deformation, so it tightly adheres to the circumferential surface of the hose 2, and water can be squeezed out and removed reliably. . Further, since the circumferential surface of the hose support portion 24b is curved, it will not be torn or scratched.

The spout head 3 has a metal fitting 31 for connecting the hose 2 connected to the base end of a main body 30 made of synthetic resin, and a water spouting head 32 is provided at the tip. This water discharge head 32 is provided with a valve element 34 that switches the flow path by operating a handle 33. In the illustrated state, water is concentratedly spouted from the central spout 35 of the water spouting head 32 in the flow path. Further, when the valve body 34 is operated to move downward, water can be dispersed and spouted from the annular discharge port 36 arranged in a ring shape. Note that 2a is a weight for facilitating storage of the hose 2.

In the above configuration, by operating the handle 8,
The mixed water can be supplied to the spout head 3 and discharged from the water discharge head 32 in a desired water discharge form. Further, washing work can be carried out by pulling out the spout head 3 from the main body 1 and grasping it with the hand.

After the spout head 3 is pulled out and used in this manner, water adheres to the surface of the hose 2, but this adhered water is drained from the drain piece 25 when the spout head 3 is returned to the main body 1. That is,
Water adhering to the surface of the hose 2 as it moves downward is wiped off by the gasket 24 inside the sleeve 21 and remains inside the sleeve 21.
It is discharged from the drain piece 25 toward the sink A. In this way, there is no adhering water on the surface of the hose 2 that has passed through the packing 24, and water, water droplets, etc. flowing along the hose 2 can be eliminated. Therefore, water droplets do not fall into the storage cabinet D, the tableware and food can be stored without adversely affecting them, and corrosion of the storage cabinet D itself can be prevented.

Moreover, since the drain piece 25 is provided by passing through both the holder 20 and the sleeve 21, the sleeve 21 will not come off from the holder 20.
Further, since the sleeve 21 is fixed by the drain piece 25, there is no need to provide a special mounting structure, and the assembly work is simple.

FIG. 5 is a cross-sectional view of the main part of another embodiment, in which rollers 40 are arranged to make the hose 2 even more smooth to take in and take out. An attachment ring 41 fitted to the base end of the sleeve 21 is supported on the roller 40 and supports the lower surface portion of the hose 2 . Further, it is preferable that the roller 40 be arranged at a portion where the hose 2 is bent.

In the case where the roller 40 is provided in this way, when the hose 2 moves, the hose 2 moves on the surface of the roller 40.
Since the hose 2 is in a rolling state, the hose 2 can be taken in and out smoothly, making it easier to handle.

[Effect of idea]

In the present invention, the hose support part is easily deformed so as to be tilted in the direction of movement of the hose due to the deformation of the thin connection part of the packing, so the resistance when inserting and removing the hose is reduced, and the usability is improved. Also,
Since the hose connection part has a curved sealing surface, it follows the movement of the hose and prevents unreasonable deformation, maintaining a good seal and improving the durability of the seal. Water intrusion is reliably prevented.
