Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a floor heating device for heating a floor finishing surface such as a cork tile, and particularly to a floor heating device in which a heat storage mortar layer under the floor is heated by hot water.

[0002]

[Prior art]

 What is called an ondol is known for heating a house. This is to burn a fire at the mouth and heat the floor by passing smoke through the flue provided under the floor, and it seems to be commonly used as housing equipment in North Korea and the northeastern part of the Chinese mainland. By heating the floor surface, heat is radiated from the feet, so that it is possible to uniformly heat the room and obtain a so-called room temperature distribution of head cold foot heat, which is preferable.

[0003]

[Problems to be solved by the device]

 However, because of differences in culture and customs in Japan, Ondol has not been adopted as a housing style and has not spread. Also, although Ondol burns firewood, coal, etc. as fuel, it was troublesome and troublesome to keep burning because it did not match the current energy situation. Moreover, it is inefficient to heat the floor with smoke.

The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to heat a floor surface with high efficiency, to perform operation management easily and easily and to automate the floor heating device. To provide.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is for heating a floor finishing surface such as a cork tile, and is a hot water pipe which is embedded in a heat storage mortar layer under the floor and serves as a hot water flow passage, and the hot water pipe. It is characterized in that it is equipped with a boiler that is connected to and supplies hot water.

[0006]

[Action]

 To describe the operation of the present invention, in a floor heating system, a hot water pipe is embedded in a heat storage mortar layer under the floor to form a hot water flow passage, and hot water is supplied from a boiler to the hot water pipe. The heat storage mortar layer is warmed by the hot water flowing through the pipe, and heat is stored. In this case, since the heat storage mortar layer is warmed with hot water, the heat exchange efficiency is good, and since the mortar has a high heat storage effect, the heat loss can be minimized.

Since the hot water from the boiler is used, it is easy to automatically control the operation of the boiler using a thermostat and a timer.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a block diagram showing a preferred embodiment of a floor heating system according to the present invention. This floor heating device is for heating a floor finish surface such as a cork tile. Basically, a hot water pipe 1 that serves as a hot water flow passage and a hot water pipe 1 are connected to the hot water pipe 1. The boiler 2 for supplying hot water is provided.

A pump 20 for transferring hot water is attached to the boiler 2, and hot water is circulated between the pump 20 and the hot water pipe line 1 connected thereto. The boiler 2 is preferably of a type that burns kerosene or gas, but an electric water heater that obtains hot water with an electric heater may be used.

The hot water pipeline 1 is made of a flexible pipe material, and a copper pipe may be used as the pipe material, but it is not optimal because it expands and contracts due to heat. For example, a seamless long plastic pipe Is preferred. In this embodiment, three systems are provided as hot water flow passages, and as shown in FIG. 2, a first system 11 that goes from the kitchen to the living room half and the dining room, and the remaining half of the living room to the hall and toilet. A second system 12 that goes through the housework room and a third system 13 that goes through each room on the second floor (not shown) are connected in parallel to the boiler 2. On the outward path 14 and the return path 15 extending from the boiler 2, on-off valves 34 and 35 are provided in series, and vent valves 44 and 45 are branched and provided, respectively. Further, three-way open / close control valves 51, 52, 53 are provided on the return path side connection portion of each system on the forward path side.

By the way, the hot water conduit 1 is not simply laid under the floor, but is embedded in the heat storage mortar layer 6 under the floor as shown in FIG. That is, on the ground on the inner side of the foundation, the embankment 70 is first applied, the crushed stone layer 71 is provided, and the soil concrete 72 having a predetermined thickness is placed thereon, and the heat insulating material 73 and the moistureproof sheet 74 are provided. The thermal storage mortar layer 6 is laid in order and provided thereon. The hot water pipeline 1 is embedded in the heat storage mortar layer 6, and wire meshes 8 for reinforcement and support are provided above and below the hot water pipeline 1, respectively.

On the heat storage mortar layer 6, a cork tile 9 is attached as a floor finishing material. As the floor finish, cork tile 9 is preferable from the viewpoint of heat conduction, but it is also considered to finish the floor with a wood flooring material although the drying efficiency is poor.

As described above, as the floor heating device, the hot water pipe line 1 is embedded in the heat storage mortar layer 6 under the floor to form a hot water flow passage, and the hot water pipe line 1 is supplied with hot water from the boiler 2. Therefore, the heat storage mortar layer 6 is warmed by the hot water flowing through the hot water pipeline 1 to store heat. As a result, heat can be radiated to the floor surface, the room can be evenly heated, and a room temperature distribution of so-called head cold foot heat can be obtained. In this case, since the heat storage mortar layer 6 is warmed with warm water, the heat exchange efficiency is good, and since the mortar has a high heat storage effect, heat loss can be minimized, that is, the floor surface can be made highly efficient. Can be warmed. Further, since the hot water conduit 1 is buried and protected in the heat storage mortar layer 6, it is excellent in safety.

Since the hot water from the boiler 2 is used, it is easy to automatically control the operation of the boiler 2 by using a thermostat and a timer, and at this time, each valve is controlled appropriately. As a matter of fact, it is easy to keep the room temperature at a predetermined level by automatic control or to start it at a preset time. That is, the operation management can be easily performed without any trouble, and the automation can be achieved.

[0015]

[Effect of device]

 As described in detail above, according to the floor heating apparatus of the present invention, the hot water pipe is embedded in the heat storage mortar layer under the floor to form the hot water flow passage, and the hot water is supplied from the boiler to the hot water pipe. The heat storage mortar layer is warmed and stored by the hot water flowing through the hot water pipeline. As a result, heat can be radiated to the floor surface, the room can be evenly heated, and so-called room temperature distribution of head cold foot heat can be obtained. In this case, since the heat storage mortar layer is heated with warm water, the heat exchange efficiency is good, and since the heat storage effect of mortar is high, heat loss can be minimized, that is, the floor surface can be heated with high efficiency. be able to. Since it uses hot water from the boiler, it is easy to automate the operation of the boiler using a thermostat and a timer, etc., so that the room temperature is kept at a predetermined level or preset. It can be easily activated at time. In other words, operation management can be performed easily and easily, and automation can be achieved.
