TECHNICAL FIELD The present invention relates to a bathroom, a kitchen,
The present invention relates to a heat insulating cover for a hot and cold water mixing tap that covers a hot water supply pipe connected to the hot and cold water mixing tap installed in a hand washing area or the like.

[0002]

2. Description of the Related Art Conventionally, various types of hot and cold water mixing taps have been provided for bathrooms, kitchens, hand washing areas, etc. Generally, hot water supply pipes and water supply pipes projecting from the wall surface are used. A form is known in which water is supplied from a water discharge pipe projecting from the mixing stopper main body after being connected to the mixing stopper main body, mixing hot water and water in the mixing stopper main body to reach an appropriate temperature.

[0003]

On the other hand, in these hot and cold water mixing taps, the surface of the end of the hot water supply pipe and the end of the mixing tap body to which the hot water supply pipe is connected is exposed.
It is said that the surface of the connection part of the hot water supply pipe to which high-temperature hot water of about 0 degrees is supplied and the mixing plug body to which the hot water supply tube is connected is at a high temperature of about 75 degrees and may be burned if touched by mistake. There was a problem. Therefore, it has been proposed to cover the hot water supply pipe laterally with a heat insulating cover. (Japanese Patent Application Laid-Open No. 8-246524) However, since only the conventional heat-insulating cover is covered, the flow rate adjusting part of the water stopcock and the lower part of the hot water supply pipe are exposed, which causes burns due to accidental touch when adjusting the amount of hot water or the temperature of the hot water. There was a problem that it might be

The present invention is intended to solve the above problems, and an object of the present invention is to provide a heat-insulating cover for a hot and cold water mixing tap which can prevent burns and is highly safe.
Another object of the present invention is to provide a heat-insulating cover for a hot and cold water mixing tap, which has high mountability and safety and can adjust the flow rate of the water stopcock without removing all the covers.

[0005]

In order to achieve the above object, in the invention of claim 1, the hot water supply pipe and the water supply pipe are installed between the wall surface and the mixing stopper body, and the mixing stopper body is also provided. A heat insulating cover made of synthetic resin for covering a hot and cold water mixing plug connected to, and at least four front, rear, upper and lower side surfaces are provided to cover all four side surfaces of the exposed surface of the hot water supply pipe. This is a heat insulation cover for a hot and cold water mixing tap.

As a result, it is possible to cover all the exposed surface portion of the hot water supply pipe, which has a high safety and enhances the prevention of burns.

In the invention of claim 2, the hot water supply pipe is connected to the back of the main body of the hot and cold water mixing tap by a connecting nut provided on the upper part of the main body of the hot water supply pipe, and the heat insulating cover covers the connecting nut. It is characterized by including.

As a result, it is possible to cover all exposed surface portions of the hot water supply pipe, which enhances the prevention of burns and provides a highly safe hot and cold water mixing tap. In particular, there is no danger of touching the connection nut of the hot water supply pipe that is hot when the hot water temperature adjusting unit is operated, and the operation can be performed with peace of mind.

In the invention of claim 3, the heat insulating cover is
It is divided into a lower cover and an upper cover, and this lower cover is provided with an engaging portion that engages with a joint portion between the wall surface and the hot water supply pipe, and the upper cover and the lower cover are provided with each other. It is characterized in that a locking portion to be engaged is formed.

As a result, the cover can be easily attached without any trouble and the clearance between the mating surfaces can be prevented. That is, it is possible to prevent the clearance of the mating surfaces and to clarify the position alignment of the upper and lower covers by matching with the engaging portions, thereby preventing the clearance of the mating surfaces and easily mounting.

According to a fourth aspect of the invention, the upper cover is
The lower cover has a substantially L shape in cross section having an upper surface and a front surface, the lower cover has a substantially L shape in cross section having a rear surface and a lower surface, and a rising portion is formed at a lower end of the front surface. While connecting the cover and the lower cover at the connecting part,
It is characterized in that the lower cover is fitted into the hot water supply pipe, and is rotated around the connecting portion so as to cover the upper cover from above.

Thus, by connecting the upper and lower separate parts whose upper side is substantially L-shaped in cross section and whose lower side is substantially L-shaped in cross section at the connecting portion, loss of each part can be prevented. . Further, with such a structure, it is possible to cover the entire hot water supply pipe and easily attach the cover.

According to the fifth aspect of the present invention, the upper cover and the lower cover are aligned at the front face with each other below the water stopper provided on the hot water supply pipe. It is characterized in that the flow rate can be adjusted.

Thus, in addition to the invention of claim 4, the lower cover is not removed and the water stop plug can be easily adjusted only by removing the upper cover. Moreover, since the alignment position is located below the center, the appearance is also improved.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below in detail with reference to the illustrated embodiments. The hot and cold water mixing valve A in the present invention is
As shown in FIG. 1, the hot water supply pipe 1 protruding from the wall surface 5 is connected to one end of the mixing stopper body 3, and the protruding water supply pipe 2 is connected to the other end of the mixing stopper 3 from the wall surface 5. The main body of the mixing stopper is formed, and the water discharge pipe 8 projects from the center of the front surface of the mixing stopper body 3. A water amount adjusting unit 6 for adjusting the amount of water discharged from the water discharge pipe 8 is provided at one end of the mixing tap body 3, and for adjusting the temperature of hot water at the other end of the mixing tap body 3. A hot water temperature adjusting unit 7 is provided.

The mixing stopper main body 3 is provided so as to project from the wall surface 5.
As shown in FIG. 4, the hot water supply pipe 1 is connected to the back surface of the mixing stopper body 3 by connecting the upper portion of the L-shaped main body pipe 1a to the back portion of the mixing stopper body 3 by means of the connecting nut 9. It is installed between 3 and. Although FIG. 3 shows the case of the hot water supply pipe 1, the hot water supply pipe 1 is also used for the water supply pipe 2.
It is installed between the wall surface 5 and the mixing stopper body 3 in the same manner as. Reference numeral 10 in the drawing is a water stop plug portion for adjusting the amount of water. Further, reference numeral 18 is a hot water supply pipe and a water drain plug for draining water from the inside of the water supply pipe.
