Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a discharge part of a water faucet in which a water supply tube connecting a discharge port and a water supply source is made of a flexible member.

[Conventional technology]

Conventionally, as the faucet, in addition to the one in which the discharge part and the valve are integrally configured, the one in which the discharge part and the valve are separately attached and both are connected by a water supply pipe are used. For example,
Shown in FIG. 7 is an automatic faucet 30 attached to the washbasin 20, which is installed on the upper surface 21 of the washbasin 21 and below the washbasin 20. The valve part 33 is
You will be informed by water pipe 40. Then, the user can
When a hand is extended to the vicinity of the discharge port 32, a sensor (not shown) provided in the discharge unit 31 outputs a detection signal, and based on this, the valve unit 33 opens the flow path to discharge water. It is a thing.

[Problems to be solved by the device]

In the faucet 30 as described above, a metal pipe such as a copper pipe is conventionally used as the water supply pipe 40 that connects the discharge portion 31 and the valve portion 33. However, the metal tube is originally not only high in material cost, but also due to the difference in shape of the discharge part 21,
Since we have to prepare the kind that matches it,
It is difficult to reduce the manufacturing cost. Also, inventory management is troublesome.

Therefore, the present inventor tried to apply a tube made of a flexible material such as synthetic resin to the water supply pipe 40.

However, if the water supply pipe 40 is flexible, it may be displaced due to vibration during water passage, and the connection with the mouthpiece forming the discharge port 32 may be loosened or disconnected to cause water leakage. Therefore, in order to prevent displacement due to vibration, a new problem arises in that complicated work such as winding a band around the water supply pipe 40 and fixing the band to the discharge part 31 with screws or the like is required.

[Means for Solving the Problems]

The present invention is a flushing discharge part having a novel structure created in view of the above-mentioned problems, and its characteristic features are:
Each of the halves of the discharge part case is provided with a discharge part case formed by joining separable half parts, and a flexible water supply tube which is installed in the discharge part case and connects the discharge port and the water supply source. Ribs are provided opposite to each other, and a cutout portion for inserting the water supply tube is formed at each abutting end portion of each rib, and an edge portion of the cutout portion contacts the water supply tube to provide an appropriate friction resistance. That is what is being done.

[Action]

With the above configuration, the water supply tube installed in the discharge part is
It is inserted between the cutouts of the ribs provided in each half of the discharge part case. The cutout portion has an edge portion that comes into contact with the water supply tube to provide an appropriate frictional resistance. Therefore, the water supply tube is held in a predetermined posture between the ribs, and the water supply tube is prevented from vibrating and misaligning. Therefore, even when the mouthpiece is attached to the discharge port of the discharge unit and the water supply tube is connected to the mouthpiece, the connection state of the both is not loosened, let alone disconnected.

Further, as described above, since the water supply tube is held only by sandwiching it between the ribs of the respective half portions of the discharge part case, the work of assembling the discharge part becomes extremely simple. In other words, wrap the band around the tube as in the past,
No complicated work such as screwing this to the discharge part is necessary.

Further, since the rib case is reinforced, the ejection portion case is reinforced, so that the strength of the ejection portion is improved.

〔Example〕

Hereinafter, the details of the present invention will be described with reference to the drawings illustrating an embodiment.

FIG. 1 is a side sectional view showing a discharge part 1 of an automatic water faucet to which the present invention is applied.

Generally, an automatic faucet has a discharge part A installed on the upper surface of a washbasin, a counter 12, etc., and a valve part (not shown) provided separately from the discharge part A and arranged under the washbasin, the counter 12, etc. And consists of. In the present invention, the flexible water supply tube 4
Thus, the discharge port 7 of the discharge unit A and the valve unit are connected.

As shown in FIG. 2, the case 1 of the discharge part A is composed of an upper half body portion 1a and a lower half body portion 1b which are vertically separable.
Both are joined by screws 9, 13 (see FIG. 1) or the like at appropriate points. In each half 1a, 1b of the discharge part case 1,
The ribs 2 and 3 are provided so as to be opposed to each other, and as shown in FIG. 3, notches 2b and 3b are formed at the abutting ends 2a and 3a of the ribs 2 and 3, respectively. The notches 2b and 3b are for inserting the flexible water supply tube 4 that is housed in the discharge part case 1, and the size thereof is such that the respective edges 2c and 3c contact the water supply tube 4. It is set so that a proper frictional resistance can be imparted.

In the discharge part case 1 configured as described above, a discharge port member 6 forming a discharge port 7, a sensor 8 for detecting a human body, an operation part 11 of a pop-up type drain plug attached to a drain port of a washbasin or the like.
Etc. are incorporated. Then, the water supply tube 4 is connected to the discharge port member 6, the signal line 5 is connected to the sensor 8, and the operating portion of the drain plug.
Operation cables 14 are connected to 11 respectively.

In this embodiment, the upper and lower half parts 1a, 1b of the discharge part case 1 are
When the water supply tube 4 is inserted between the cutouts 2b and 3b of the ribs 2 and 3 that are joined and abutted with each other, the ribs 2 and 3 are angled with respect to the arrangement direction of the water supply tube 4. Has been formed. Therefore, by appropriately setting the sizes of the cutouts 2b and 3b, the edge portions 2c and 3c come into contact with the surface of the water supply tube 4 and an appropriate frictional resistance is generated between them. At this time, the water supply tube 4 may be slightly curved so as to come into contact with the edge portions 2c and 3c.

By the way, when the sensor 8 is incorporated in the ejection portion 1 as in the embodiment shown in FIG. 1, it is necessary to insert the ribs 2 and 3 into the signal line 5 as well. If the water supply tube 4 and the signal line 5 are covered together to form a single cord, the notches 2b and 3b may be provided in the ribs 2 and 3, respectively, as shown in FIG. Alternatively, as illustrated in FIG. 4, notches 2d and 3d for inserting the signal line 5 can be separately formed in the ribs 2 and 3.

Further, since the water supply tube 4 is flexible, it can be slightly compressed so as to come into contact with the edges 2c, 3c of the cutouts 2b, 3b. For example, the embodiment shown in FIG.
The opening areas of the cutouts 2b, 3b when they are butted are made slightly smaller than the outer diameter of the water supply tube 4, and the cutouts 2b, 3b are
The edges 2c and 3c of b are designed to hold the water supply tube 4 in a compressive manner. By doing this, the water supply tube 4
The holding state of is further strengthened.

Further, the ribs 2 and 3 may be formed not only to bring the end faces into close contact with each other when the respective half portions 1a and 1b of the discharge part 1 are joined, but also to overlap the front and rear sides as shown in FIG. Good. By adopting this configuration, the tolerance range of the height dimensions of the ribs 2 and 3 can be made large, so that the manufacturing efficiency can be improved.

In the above-described embodiment, the discharge case 1 is vertically separable, but instead of this, the discharge case 1 can be divided.
May have a structure that can be divided into left and right. Besides, the specific configuration of the present invention can be appropriately changed according to the embodiment.

[Effect of device]

As is clear from the above description, in the discharge part of the faucet according to the present invention, the flexible water supply tube is inserted into the notch part of the rib provided in the discharge part case, and this is provided at the edge part of the notch part. Since they are brought into contact with each other to provide a proper frictional resistance, it is possible to prevent the water supply tube from being displaced due to vibration during water passage. Therefore, since the connection between the water supply tube and the discharge port is not loosened or disconnected, there is no possibility of water leakage.

To install the water supply tube in the discharge part, it is only necessary to hold the water supply tube between the ribs and join each half of the discharge part case, so the assembly work of the discharge part is extremely easy. is there.

Further, since the rib provided on the discharge part case also functions as a reinforcing material, the strength of the discharge part is improved.

As described above, the present invention exhibits excellent practical effects.
