Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a heat insulating cap attached to the tip of a water discharge pipe of a mixing faucet.
[0002]
[Prior art]
The conventional mixing faucet is equipped with a heat insulating cap made of synthetic resin at the tip of the water discharge pipe when the water discharge pipe is swung horizontally when the water discharge pipe is hot due to continuous hot water discharge. , Even if you touch it, the heat of the hot water is not transmitted so that you will not get burned.
[0003]
However, normally the heat insulating cap is firmly connected so as not to come out of the water discharge pipe, and does not have the function of rotating only the heat insulation cap with respect to the water discharge pipe, and the water discharge direction is always downward and constant, and the water discharge range is narrow. It was inconvenient.
[0004]
[Problems to be solved by the invention]
The problem to be solved by the present invention is to improve the usability of a sink and a wash basin by widening the water discharge range even when a heat insulating cap is attached to the tip of the water discharge pipe of the mixing faucet.
[0005]
[Means for Solving the Problems]
In the heat insulating cap attached to the tip of the water discharge pipe of the mixing faucet according to the first aspect of the present invention, the heat insulating cap is attached to the tip of the water discharge pipe via a connecting member and a stopper member. Is attached to the distal end surface of the water discharge pipe with a screw to form a recessed portion into which the connecting member is inserted, and the connecting member is formed by adjoining the insertion groove and the flange portion to be inserted into the recessed portion of the retaining member. The connecting portion is attached so that the flange portion is sandwiched between the retaining member and the water discharge pipe so that the flange is rotatable and does not come out of the water discharge pipe, and a heat insulating cap is fitted to the connection member. Thus, the heat insulating cap is rotatable with respect to the water discharge pipe.
[0006]
According to a second aspect of the present invention, the angle of rotation of the heat insulating cap is restricted by the protrusion of the integrally connected connecting member rotating only between a pair of stopper portions formed on the inner peripheral surface of the water discharge pipe. It is.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
The mixing faucet 1 of this embodiment is fixed to a sink or a wash basin or the like, and a water discharge pipe 3 is attached so as to be pivotable in the horizontal direction as shown in FIG. Water can be supplied to the outside. As shown in FIGS. 2 to 4, a heat insulating cap 19 that is integrally coupled to the connecting member 6 via a retaining member 15 is attached to the tip of the water discharge pipe 3.
[0008]
The connecting member 6 is horizontally long and has a substantially cylindrical shape with a water passage 7 formed therein. A part of the connecting member 6 projects in a circular arc shape from the front end surface facing the outlet of the water discharge pipe 3 to form a protrusion 8, The insertion groove 9 and the flange portion 10 formed in the middle portion of the outer peripheral surface are adjacent to each other, and the water passage 7 is formed with an opening portion 11 communicating with the outside at the lower portion of the other end. In addition, a plurality of ring grooves 13 for fitting sealing O-rings 12 are formed on the outer peripheral surface of the connecting member 6 at appropriate intervals.
[0009]
The retaining member 15 is for rotatably attaching the connecting member 6 to the water discharge pipe 3 and prevents the connecting member 6 from coming out of the water discharging pipe 3. An inverted U-shaped concave notch 16 is formed by cutting a pair of screw holes 17, 17 at the left and right ends of the concave notch 16, and a connecting member 6 is attached to the water discharge pipe 3. Before coupling the heat insulating cap 19 to be connected to the connecting member 6, first, the recessed portion 16 of the retaining member 15 is inserted into the mounting groove 9 of the connecting member 6, and the screws 18, 18 are screw holes 17, 17 of the retaining member 15. If the connection member 6 is inserted into the screw holes 4 and 4 and fastened to the screw holes 4 and 4, the protrusions 8 of the connection member 6 are formed on the inner peripheral surface of the outlet of the water discharge pipe 3 at appropriate intervals. The connecting member 6 can be rotated within the range of contact with the By Nji portion 10 is pinched between the retaining member 15 exits the distal end of the water discharge pipe 3, never exit from the water discharge pipe 3.
[0010]
In addition, it is good also as a 360 degree rotation of the connection member 6 by deleting each stopper part 5 and 5a from the water discharge pipe 3, or deleting the protrusion 8 of the connection member 6. FIG.
[0011]
The heat insulating cap 19 is made of a horizontally long synthetic resin having heat insulating properties, and is fitted to the outer periphery of the connecting member 6 rotatably coupled to the water discharge pipe 3, and then the stopper 20 is screwed into the screw hole 21 of the heat insulating cap 19 from below. And is integrated with the screw hole 14 of the connection member 6 to prevent the connection member 6 from coming off and rotating, and the water discharge pipe 3 can be rotated together with the connection member 6.
[0012]
A water discharge portion 22 is provided on the lower surface of the front end of the heat insulating cap 19 so as to communicate vertically with the water passage 7 of the connection member 6. A rectifier 24 is interposed between the water discharge portion 22 and the water discharge cap 23 below the water discharge portion 22. In this state, the water discharge cap 23 is screwed, and the mixed water that has passed through the rectifier 24 is discharged to the outside.
[0013]
In this way, in the present invention, if the heat insulation cap 19 is held and rotated, it rotates together with the connecting member 6 and is held at an arbitrary position by the frictional resistance of the O-ring 12, and the direction of the water discharge cap 23 is only downward as shown in FIG. In addition, since it can be changed to the left or right or above, the water discharge area can be greatly expanded when used in a sink or a washstand.
[0014]
【The invention's effect】
Since the present invention has the above configuration, it has the following advantages.
(1) A heat insulating cap attached to the water discharge pipe tip of the mixing faucet is attached to the water discharge pipe front end via a connecting member and a retaining member, and the retaining member is attached to the front end surface of the water discharge pipe with screws, A recessed portion into which the connecting member is inserted is formed, and the connecting member is formed so that the insertion groove and the flange portion to be inserted into the recessed portion of the retaining member are adjacent to each other, and the flange portion is formed with the retaining member and the water discharge pipe. Since the connection member can be rotated and attached so as not to come out of the water discharge pipe , and the heat insulation cap is fitted to the connection member, the connection member is rotatable with respect to the water discharge pipe. Even when hot water is discharged, the heat insulating cap can be freely rotated to change the direction of water discharge, and the water discharge area is expanded, so that the usability of the mixed water faucet at the sink and wash basin is greatly improved.
(2) Since the rotation angle of the heat insulating cap is regulated by the stopper portion of the water discharge pipe, there is no possibility that the mixed water will protrude from the sink, the wash bowl, etc., and soak the floor and the like.
