Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an improvement of the header of a mat for hot water floor heating, which is used to distribute hot water between an outgoing path and an incoming path.

[Problems that conventional technologies and ideas try to solve]

Conventionally, as a device for keeping warm in the winter, there has been a movable or foldable floor heating mat that has a built-in heat source and is placed on the top of the floor.

By the way, there are two types of floor heating mats: electric heating type mats with a built-in heater, and mats with built-in water pipes for supplying hot water into the mat.

Of these, the former has the advantage of being easy to handle, easy to adjust temperature, and is highly safe, but has the disadvantage of high heating costs such as electricity.

An example of a floor heating mat having the latter structure is shown in FIG. In other words, stove b uses water stored in tank a as a heating source.
The waste heat is used to heat the water to make it hot.
This hot water is then pressure-fed by a pump P, distributed to, for example, two water pipes f and f arranged in parallel inside the water-conducting main pipe c, the header body d, and the mat e, and then sequentially sent to this water pipe. After heat is radiated through the two water pipes f and f, the cooled hot water is returned to the tank a through the drain pipe g, and is circulated by being sent to the header body d again, thereby providing warmth.

However, in the conventional hot water heating mat having such a structure, the two water pipes f, f are disposed in the same direction, facing each other in the mat e, so the water pipes f,
The hot water flowing in f is on the outlet side f ₂ , rather than the inlet side f ₁ , f ₁
The temperature of f ₂ becomes lower. Therefore, there was a drawback that the heat radiation temperature from the pine e was uneven, and the temperature distribution of the pine e was not uniform.

[Purpose of invention]

The present invention was developed in view of the above-mentioned points, and its purpose is to reverse the forward and return paths of adjacent flow paths among the plurality of hot water flow paths flowing inside the mat. To provide a header of a pine for hot water heating, which allows even distribution of heat radiation by hot water from the pine.

For this reason, as shown in Fig. 1, the outgoing path A and the incoming path B of hot water sent through two rows of water pipes f and f arranged inside the mat e are different from the conventional header in which the outgoing path A and the returning path B are arranged in the same direction. The difference is that there is a stove B inside Matsutto e.
This is because hot water from the inlets 6a, 6a, which has a high temperature and is sent by the main pipe 4, and hot water from the outlets 6b, 6b, whose temperature has decreased due to heat radiation, interact with each other. The heat radiation from the pine e has an evenly averaged distribution.

In this case, the number of water guide passages formed on the outer circumferential surface of the water divider body 3 must correspond to the number of water guide tubes and drain tubes to be connected. In addition, in the above embodiment, the water guide passages 3a, 3b, 3 to form the flow passages are
c are formed so as not to three-dimensionally intersect with the outer peripheral surface of the water divider body 3;
It may be formed so that it does not three-dimensionally intersect inside the.

[Effect of idea]

As mentioned above, the present invention connects some of the plurality of water conduction slave pipes and drainage slave pipes branched from the water conduction main pipe and drainage main pipe connected to the header body to the water supply pipe inside the mat. In addition, a water guide passage as a flow path is formed on the outer peripheral surface of the water divider body, which is inserted into the header body so as to cut at least one of the water guide tube and the drain tube so as not to intersect with each other three-dimensionally. Since the water pipes are connected to at least one of the water conduction sub-tubes and the drainage sub-tubes, the forward and return routes of the plurality of water pipes disposed within the mat are in opposite directions. Therefore, the heat radiation distribution of hot water from the pine can be evened out evenly.
