Description

  The present invention relates to a hot water supply apparatus and a floor heating system. More specifically, the present invention has a simple configuration, and is floor-mounted and portable, yet lightweight and can easily apply a considerable amount of water in a short time. The present invention relates to an economical and maintenance-free eco-type water heater and floor heating system that can be heated.

  Conventionally, as a means for warming water, it is formed using a material having a suitable high thermal conductivity, and water is poured into a container such as a pot, a kettle or a pan, and an electric heating stove or gas stand is used. Heat the water inside the container to warm it, or apply a flame from a gas to the pipe from the outside of the pipe while flowing the water through a pipe formed using a material with appropriate thermal conductivity. The method of warming the instant water heater type that heats the flowing water inside the pipe is common, but in such conventional warming method, the heat exchange rate is remarkably low, so the amount of heat energy loss is at a high level. Because it remains, economic loss is incredible and it cannot be denied that it is uneconomical.

As a method for improving such an economically disadvantageous situation, for example, a linear electric heating element including a heating wire, that is, a two-chrome wire is directly immersed in the water in the container, and the electric heating energy is directly supplied. A method of heating to water by transferring to water, or a method in which an electric heating element is directly attached or attached to a part of the water-containing container and water is heated from that part is also adopted. However, the heat exchange rate is only about 20% at best, and the situation where it is still impossible to escape from an economically disadvantageous situation continues.

On the other hand, in recent years, as a technique for using a heating element having a higher heat exchange rate, an appropriate electrode is connected to a heating layer in which electrical resistor particles are printed on a substrate, and the heating layer is energized to generate heat. A method of boiling warm water using a heating element, for example, a heating element called PTC, is disclosed in, for example, JP-A-2002-204749 (Patent Document 1), JP-A-2008-168098 (Patent Document 2), Or it is disclosed by Unexamined-Japanese-Patent No. 2011-88506 (patent document 3) etc.

For example, in Patent Documents 1 and 2, instead of using a conventional dichrome wire, an example of using a heating element in which an ink made of an electrical resistor mainly composed of a metal oxide is screen-printed on an appropriate substrate is used. However, there is no disclosure or suggestion regarding the technology using the carbon-based fine particles having the highest heat generation efficiency.

On the other hand, Patent Document 3 discloses a technology that uses a PTC heating element using carbon-based fine particles in a hot water generator, and the heating element of such a system certainly has a relatively high temperature due to low power. Although an economic merit is expected in that a heat generation effect can be obtained, in Patent Document 3, basically, both the front and back surfaces of the PTC heat generating element are covered with electrodes. Further, since the outer surface is used in the form of being covered with a considerably thick coating material, the heat generated by the PTC heating element is not sufficiently transferred to the liquid. It is extremely difficult to obtain a heat exchange rate of more than 10%.

On the other hand, Japanese Patent No. 3894577 (Patent Document 4) discloses a technique of using a soot layer as a part of a heating element of a water heater, but in Patent Document 4, the soot layer is It is formed on a suitable substrate, and the heat generation layer is only formed on the soot layer, and the technology that the soot layer covers the surface of the heating element made of carbon-based fine particles. There is no disclosure or suggestion regarding.
Therefore, at present, the related art is only applied to a small water capacity container such as a desktop small water heater or a hot water generator mounted on an automobile, and a larger water tank, for example, 20 to 40 liters. For example, a hot water generator equipped with a water tank of a level that can be used for a floor heating system cannot be used at all.

Hereinafter, the configuration of each specific example of the hot water supply apparatus according to the present invention and the floor heating system using the same will be described in detail with reference to the drawings.
That is, FIG. 1 is a diagram showing a configuration of a specific example of a hot water supply apparatus 1 according to the first aspect of the present invention, in which a predetermined size (for example, its length and width are respectively shown). A predetermined thickness and a predetermined thickness made of a material including at least conductive particles, which is formed on at least a part 5 'on at least one surface 5 of the substrate 4 made of an insulating member having a heat insulating property having a thickness of about 20 cm to 100 cm. A sheet-like heat generating layer 6 having a width and a length, a pair of electrode parts 8 provided at appropriate portions of the sheet-like sheet-like heat generating part 7, and the pair of electrodes A heating element 50 composed of an electric wiring part 9 electrically connected to each of the parts 8, and the amount of heat emitted from the heating element 50 that generates heat by energization is directly Consists of appropriate members either manually or indirectly The temperature of the liquid 18 is raised or kept at a predetermined temperature by being transmitted to the liquid 18 containing water-like liquid contained in the water tank 2 having an appropriate internal capacity. The hot water supply apparatus 1 comprised by is shown.
In the specific example of the present invention, as the predetermined dimension of the belt-like heat generating layer portion 6, for example, the length in the longitudinal direction is 20 to 100 cm, and the length in the width direction is It is desirable that the thickness is 3 to 100 cm and the thickness is 0.1 mm to 3.0 mm.

  That is, as described above, the hot water supply apparatus 1 according to the present invention is a general electric pot configured with a small liquid capacity of a desktop type or an in-vehicle type for boiling water using conventional electricity or keeping warm. , A hot water generator having a slightly large liquid capacity of about 20 to 40 liters, which is used in a field that is fundamentally different from electric water heaters, electric hot water feeders, etc. In the floor heating panel group, which is arranged on the floor surface to circulate the hot water and keep the floor surface temperature at a predetermined temperature level, and an appropriate hot water circulation pipe or pipe is built in the floor surface. The hot water having a predetermined temperature is supplied into the circulation pipe, and the liquid containing the water in which the water temperature once circulated and returned through the floor heating panel group is reduced to a predetermined temperature or less is stored. Again, the return liquid In a system where the temperature is raised to a predetermined temperature, the floor can be placed at any place, indoors or outdoors, which can reduce costs related to management and maintenance efficiently and economically. This is a hot water supply device 1 that is lightweight and portable.

Further, a further feature of the hot water supply device 1 according to the present invention is that conventionally, electric energy is used to heat a heat generating portion made of electrically conductive conductive particles, for example, called PTC or NTC. The method of using a linear heating element is also known in the above prior art documents, etc., but in the conventional configuration of the heating element, the heating part 7 made of the conductive particles is fragile. Therefore, since the outer periphery of the heat generating part 7 is used by completely covering a coating layer made of a considerably thick electrical insulator, the heat exchange rate for the input electric energy is extremely low. In addition to the inefficiency, the structure of the water heater is complicated accordingly, so that it becomes expensive and at the same time a considerable loss is caused economically.

However, the heating layer portion 6 itself is strong, has excellent wear resistance, Since it becomes possible to form the heat generating layer 6 having a large peel strength from the surface, it is necessary to cover the heat generating layer 6 with a covering made of a thick insulator as in the prior art. Since it functions as the heat generating layer part 6 as it is, most of the heat energy released from the heat generating part 7 comprising the heat generating layer 6 is transmitted to the liquid part in the water tank part 2, for example, water. As a result, the heat exchange rate is significantly improved compared to the conventional technology. .

Furthermore, in the present invention, since the area of the planar shape of the heat generating layer portion 6 can be set large, as an extreme example, the size is equal to the outer surface of one side wall portion of the water tank portion 2. It is possible to form the heat generating layer portion 6 having the area of 5 mm on the heat insulating material layer portion 4 and to have the heat generating body portion 50 that has become the heat generating portion 7.
