Description of the Related Art The most basic type of hot and cold water mixing faucet is that a water valve and a hot water valve are incorporated in flow paths on a water side and a hot water side, respectively, and these are opened and closed by a rotary operation handle. Also, a thermostat mixing valve or the like incorporating an automatic temperature control mechanism has a structure in which a flow rate and a temperature are controlled by rotation of an operation handle provided on a main body side. The basic structure of a single-lever type hot and cold water mixing faucet is to adjust the flow rate and temperature by moving a lever provided at the upper end of the faucet body up and down and left and right.

のものが殆どである。[0003] In these hot and cold water mixing faucets, a handle or lever for operation thereof is attached to the faucet main body, and a discharge pipe protrudes forward from the faucet main body, and is attached to a sink or the like. Most of the hot and cold water mixing faucets have such a configuration.

っても使い辛い面がある。However, since the faucet main body is disposed on the counter or wall behind the sink, the user has to extend his arm when operating the handle or lever. For this reason, the user is required to work in a posture in which the waist is bent forward, so that a burden is easily applied to the waist, and there is a problem that the child is hard to use.

温度調整用のハンドルを設けた構成が記載されている。[0005] To solve the problem of operability of such a hot and cold water mixing faucet, for example, as described in US Pat. No. 3,415,280, a sleeve having a discharge portion facing downward and a valve mechanism built in. Is provided with a knob for operation at the tip of the nozzle, and the mixed water is discharged by rotating the knob. German Patent Publication DE 3120210A1 also discloses a configuration in which a lever for adjusting the flow rate and a handle for adjusting the temperature are provided at the end of a sleeve having a valve mechanism and the like.

したがって、スリーブは固定した姿勢とする以外にな
く、吐出部の位置が変えられないことからくる使い勝手
への影響は避けられない。However, in the former specification, since the base end of the sleeve is fixed, there is no mechanism for changing the position of the discharge section at the front end. That is, water and hot water flow paths are incorporated in the sleeve, and these flow paths are connected to the supply pipe on the building side. However, since the supply pipe side is fixed, the sleeve is rotated. Then, twisting or bending occurs at the connection point between the internal flow path and the supply pipe side.
Therefore, the sleeve has a fixed posture, and the influence on usability due to the inability to change the position of the discharge unit is inevitable.

ある。In the latter publication, the sleeve can be turned, and the position of the discharge section at the tip can be changed in the same manner as in a normal water discharge pipe. This is intended to cope with the turning operation of the sleeve by using flexible hoses for the supply pipes on the water side and the hot water side which pass through the member for fixing the base end of the sleeve.

ほか漏水の問題も無視できない。However, when the sleeve is turned, the elastic reaction force of the flexible hose itself also reaches the sleeve, so that the turning operation tends to be heavy. Especially,
The hose becomes stiff when the flexible hose is twisted or when the supply pressure of water and hot water is high.
It often interferes with light operation. In addition, since the flexible hose is repeatedly subjected to stress each time the sleeve is turned, the hose itself may be fatigued, the connection part with the supply pipe may be loosened, etc., resulting in poor durability and water leakage. Cannot be ignored.

特徴とする。According to the present invention, a valve is provided in the spout for opening and closing the flow paths of water and hot water, respectively, and an operating means for operating the valve is provided on the discharge end side. A hot-water mixing faucet, comprising a fixture for rotatably connecting the base end of the spout around its axis and fixing the spout to a faucet installation portion, the fitting connecting water supply and hot water supply piping, It is characterized by having a flow path structure capable of connecting the flow path of the water and hot water from the water supply and hot water supply pipes to the flow path to the valve side in the entire range of the rotation angle of the spout.

Can be maintained in a state where the flow path from is communicated with the mixing valve. Therefore, the spout turning operation, which has occurred in the case of connecting the flow paths by a flexible hose or the like, does not become heavy, and handling with a light touch is possible.

A flow path from one of the water supply and hot water supply pipes is opened at the bottom of the chamber and the flow from the other is provided. The passage is opened from the peripheral surface of the chamber, and the base end surface of the spout is set to have a clearance with the bottom surface of the chamber, and the flow paths of water and hot water are respectively opened at the base end and the peripheral surface of the spout. The flow path opened to the peripheral surface was connected to the flow path of water and hot water of the spout by aligning the water side and the hot water side via a swivel joint structure and the flow path opened to the bottom of the chamber via a gap. It may be a thing.

As shown in the cross-sectional view taken along the line B) and the exploded perspective view of the main part in FIG. 6, a ring 9c protruding the pin 9b is extrapolated, and the lever 10 is inverted U which can extrapolate the pin 9b from above. A hook 10a having a bifurcated portion is connected via a support shaft 10b. The pin 9b is inserted into a slit 8e formed at the tip of the movable valve body 8 to transmit the rotation of the spindle 9a to the movable valve body 8.

The movable valve element 8 is set at the rightmost position, and at this time, the water inlet 8b and the hot water inlet 8c are so arranged as to be shifted from the communication holes 7d and 7e toward the distal end. Accordingly, the flow path for the water supply and hot water supply flow paths 7c and 7d of the fixed valve body 7 is shut off, so that there is no discharge from the discharge head 6. When the lever 10 is pushed down in the direction indicated by the dashed line, the movable valve body 8 moves to the left, and the water and hot water inlets 8b, 8c are connected to the communication holes 7d, 7e, respectively.
To match. Therefore, since the degree of matching of the communication ports 7d and 7e increases in proportion to the amount of movement of the movable valve body 8, the supply flow rates of water and hot water also increase, and the lever 10
Can adjust the flow rate of the mixed water.

The pressure of water supply and hot water supply can be reduced. Therefore, these water supply and hot water supply hoses 1
6 and 17 are not excessively hardened by the supply pressure, and no resistance acts on the operation of rotating the sleeve 12. Therefore, the position of the water discharge head 13 can be easily changed by simply pushing the sleeve 12 lightly, and even if the hoses 16 and 17 are used for water supply and hot water supply, the usability thereof is not hindered. Also, in the case of using the hoses 16 and 17 for water supply and hot water supply as described above, a complicated swivel joint structure as in the previous example is not required, and the structure is further simplified.

This forms a downwardly convex loop. Around the hoses 16 and 17, there is provided a cover 21 that covers a portion from a connection point with the pressure reducing valve 20 to a base end of the water discharge head 13 through the inside of the sleeve 12.

Can guide you not to. Therefore, even if the water discharge head 13 is removed from the sleeve 12 when the water discharge head 13 is removed, the water discharge head 13 can be removed without tension because the hoses 16 and 17 have room for the loops, and the cover 21 can be connected to the hose 21 without tension. Since the guides 16 and 17 are guided, a quick movement is possible.

もので済むようになる。Further, in the case where a water supply and hot water supply hose is inserted into a hollow sleeve and these are connected to a water discharge head, a water supply pressure and a hot water supply pressure can be reduced by providing a pressure reducing valve upstream of the hose. As a result, the hose in the sleeve is prevented from becoming hard, and the turning operation of the sleeve can be performed lightly. Further, since the hose can follow the turning of the sleeve even if the hose is simply connected directly to the water discharge head due to the flexibility of the hose, the connection structure of the flow path can be simplified.
