Description

  The present invention relates to a faucet with a branch port that is installed on a counter in a kitchen, a kitchen, or a bathroom, and is connected to an alkali ion generator or a dishwasher.

As a prior art, there is one already disclosed in JP-A-2002-4363 (Patent Document 1). As shown in FIG. 6, the configuration includes a faucet body 54 having a hot water channel 51 connected to a hot water supply pipe 50 and a water channel 53 connected to a water supply pipe 52, and hot water and water flow from the hot water channel 51. A water discharge pipe 55 that discharges mixed water mixed with water from the channel 53, a hub 56 that is rotatably assembled to the faucet body 54, and a hot water branch port 57 that communicates with the hot water flow path 51. There is disclosed a faucet with a branch port in which a hub 56 of a faucet with a branch port provided to the faucet body 54 is rotatably assembled with respect to the faucet body 54. ing.
Further, Patent Document 1 is characterized in that the rotation resistance of the hub 58 is larger than the rotation resistance of the hub 56.

  That is, with this configuration, even if various articles touch the hot water branch port 57 or the hose connected thereto, the rotation resistance of the hub 58 is made larger than the rotation resistance of the hub 56. Therefore, the hot water branch port 57 provided in the hub 58 does not rotate easily, and the user can solve the problem that the user touches the hot water branch port 57 located in an unexpected place and is burned. Yes.

JP 2002-4363 A

However, in the prior art, there is a possibility that the hot water branch port 57 may be rotated due to a strong impact, and as a result, there is a risk that the hose of other equipment connected to the hot water branch port 57 may be violated. Further, since the hub 58 is also a rotating member, there is a problem that the risk that the seal portion is broken and water leaks cannot be denied.
Accordingly, in order to solve the above-described problems in the present invention, an object is to provide a faucet with a branch port that does not cause a hose connected to other equipment to be violated and there is no risk of water leakage even when there is a strong impact. And

In Claim 1 of this invention, it has the main part which has the water side flow path connected to a water side piping, the hot water side flow path connected to a hot water side piping, and a hot water mixing flow path, and the spout which discharges hot water. The main body part has a branch channel communicating with the water side channel or the hot water side channel, and has a branch port for branching water to other devices and a branch member connected to the branch port. Because
The branch flow path communicating with the branch port is opened at two positions at opposing positions, and the branch port on the side where the branch member is not connected is closed with a cover.
Thereby, even if it is a case where a dishwasher is connected through the branch member from the branch port by the side of hot water, it becomes possible to install in either right and left. Further, since the branch member is fixed to either the left or right side and the branch member does not rotate, the hose of other equipment does not break.
Moreover, since there is no sliding part in a main-body part, there is no danger of the water leakage by a secular change.

According to a second aspect of the present invention, the main body is fitted with a cylindrical cover, the inner diameter of the cover is substantially the same as the outer diameter of the main body, and is rotatable with respect to the main body. Has one opening for fitting the capping lid at one branch port, and after fitting the capping lid, it is configured to rotate to the other branch port.
This makes it possible to hide the branch port on the unused side with the cover, thereby improving the design of the faucet itself and eliminating the risk of accidentally removing the capping lid and causing water leakage.

According to claim 3 of the present invention, the branching member can be installed on either the upper part or the lower part of the spout.
Thus, for example, if the connection position with other equipment to be used is above the faucet, the branching member is appropriately changed above the spout, and if it is below, the branching member is appropriately changed below the spout. This makes it possible to effectively use the kitchen space.

In Claim 4 of this invention, it has a main part which has the water side flow path or hot water side piping connected to a water side piping or a hot water side piping, and the spout which discharges water or hot water, The said main body part is a water side. A water faucet with a branch port having a branch channel communicating with the channel or the hot water side channel, and having a branch port branched to another device and a branch member connected to the branch port,
Two branch flow paths communicating with the branch port were opened at opposing positions, and the branch port on the side where the branch member was not connected was closed with a lid.

This makes it possible to install other devices on either the left or right, as appropriate, depending on the position of the single faucet that discharges water or hot water installed in the kitchen to be used. The hose will not run wild.
Moreover, since there is no sliding part in a main-body part, there is no danger of the water leakage by a secular change.

Even when there is a strong impact on the branch member connected to the faucet body, it is possible to provide a faucet with a branch port without causing a hose connected to another device to be violated and without risk of water leakage.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is an external perspective view showing an embodiment of the present invention. In FIG. 1, the faucet indicates a hot and cold water mixing faucet. That is, the faucet body 1 includes a rotating member 3 connected to a spout 2 for discharging hot water, a cartridge pressing cover 4 on the rotating member 3, and a handle 5 connected to an operation shaft 30 of a cartridge 29 described later. A branch member 6 communicated and connected to the main body 13 is provided at the lower part of the faucet main body 1. Furthermore, the spout 2 has a water outlet 7 for discharging hot water at the tip.

A cover 8 is fitted on the lower part of the faucet body 1, and a cap 9 for concealing a screw 25 for fixing the faucet body 1 is fitted on the front surface of the cover 8.
Further, the branching member 6 includes an opening / closing handle 10 and a coupler unit 11 for operating water discharge to other devices, and has a structure including a water stop valve 12 at a tip portion of the coupler unit 11.

FIG. 2 is a cross-sectional view of a branch joint portion in the case of a single water faucet according to an embodiment of the present invention.
A water-side flow path 14 communicating with the water-side pipe is formed in the main body 13, and a valve body (not shown) and a handle for operating the water discharge amount are provided on the upper portion of the main body 13. Yes.
The branch structure of the present invention will be described with reference to FIG. A water channel 14 is formed in the main body 13, and a branch channel 26 is provided so as to be orthogonal to the water channel 14. In the example shown in FIG. 2, the branch flow path 26 is provided in the left-right direction. That is, if the connection direction to the other device is the left side of the faucet body 1, the branch joint 15 is screwed into the left branch port 17 via the seal material 35 as shown in FIG. In other words, the lid 16 is fitted into the other branch port 17 via the sealing material 36, and the main body 13 is configured to fit the cover 8.

Next, the connection between the branch flow path 26 provided in the main body 13 and the cover 8 will be briefly described. An opening 18 having a diameter larger than that of the opening is provided in a side portion of the cover 8 at a portion corresponding to the opening of the branch channel 26. After the user determines the installation direction of the branch joint 15, the user aligns the opening 18 of the cover 8 with the branch port 17 that does not use it. Next, the cover 16 having a male screw is screwed into the branch port 17 through the seal member 36, and then the cover 8 is rotated. The branch joint 15 having the male screw at the tip is aligned with the other branch port 17 through the seal member 35. They are screwed together. A groove is formed in the cover 16 for a firm attachment using a screwdriver on the surface in order to improve water tightness with the branch flow path 16. Here, the sealing materials 35 and 36 use O-rings, but are not particularly limited to O-rings as long as they maintain water tightness.
Therefore, when the user installs another device on the right side of the faucet body 1, the right branch port 17 may be used, and the other branch port 17 may be blocked using the closing lid 16. And since the main-body part 13 does not slide and is fixed, since a seal part does not deteriorate by a secular change, there is no danger of leaking from a seal part.
Further, since the opening 18 of the cover 8 is not visible because the branch joint 15 is screwed into the opening 18 provided in the cover 8, the design of the faucet body 1 is improved and it is accidentally blocked. There is no risk of removing the lid and leaking water.

  In FIG. 2, a single faucet that discharges water has been described, but the present invention can also be implemented in a single faucet that discharges hot water. In that case, in the description of FIG. 2 described above, the water side pipe becomes the hot water side pipe, and the water side flow path 14 is replaced with the hot water side flow path.
