In this manner, the heating efficiency can be improved, and the durability and water-resistance etc. can be improved, compared to the tatami mat.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a floor heating device using a hollow casing installed on the floor.

[Prior Art] Underfloor heating systems are ideal in terms of comfort, and have been widely used in the past, ranging from ondol-style heating systems designed to heat the building itself to simple heating systems such as electric heating carpets. ing. However, the former type, Ondol, requires high equipment costs, and the latter type, electric heating carpet, has drawbacks such as being susceptible to water and having relatively high heating costs.

[Object of the Invention] An object of the present invention is to provide a comfortable floor heating device that can be laid on the floor like a tatami mat, has good durability, has excellent heating efficiency, and is comfortable.

[Summary of the Invention] The gist of the present invention for achieving the above-mentioned object is to lay a flat hollow casing having an air inlet and an air outlet on the floor,
This floor heating device is characterized by circulating warm air through the hollow part of the hollow casing.

[Embodiments of the invention] The present invention will be explained in detail based on illustrated embodiments.

FIG. 1 shows an embodiment of the floor heating device according to the present invention, which includes a hollow mat 2 and a hollow rug 2 constructed by combining a number of hollow casings 1 of appropriate sizes on the floor as illustrated in FIG. 2 and below. It consists of a heat generating unit 3 and an exhaust unit 4, which feed air at an appropriate temperature into its interior.

Each hollow housing 1 is made of synthetic resin material or light metal with good heat resistance, and is, for example, a flat hollow body in the shape of a square or rectangle with a side length of approximately 30 cm and a thickness of approximately 3 cm. has an air inlet la and an air outlet lb,
When combined on the floor, each air outlet 1b is sequentially connected to the air inlet 1a of the adjacent hollow housing 1, so that the hollow parts of all the hollow housings 1 are arranged so as to communicate with each other, and a connecting member (not shown) is used. are fixed to each other. A heat generating unit 3 having a heater 3a and a blower 3b is connected to the air inlet 1a closest to the inlet side, and an exhaust unit 4 having an exhaust port is connected to the air outlet 1b closest to the outlet side.

For manufacturing reasons, each hollow casing l has a main body 1c and a bottom 1d.
The main body 1c and the bottom 1d are connected to each other.
They are not necessarily made of the same material, and the bottom portion 1d may be made of a flexible and heat-insulating material intended only for air sealing. Inside the hollow housing 1, a reinforcing body 1e for maintaining mechanical strength and a guide wall 1f for guiding air flow are provided.
etc., but the reinforcing body 1e and the guide wall 1f
can also be used for both purposes.

Furthermore, for the purpose of improving comfort, hiding the hollow casing 1, or improving the heating effect, a carpet 5 or other material is applied to the surface of each hollow casing 1, as shown in FIG. It can also be attached to many hollow casings.
After combining them as shown in FIG. 1, they can be collectively covered with a common carpet.

Each hollow casing 1 is provided with an appropriate uneven portion on the side for positioning when assembled, and the adjacent hollow casing l
The connecting member, which is a separate member, may be omitted so as to engage with the uneven portion of the connecting member. The air inlet 1a and air outlet 1b provided on the side wall of each hollow casing l may be simple holes or notches, or the air inlet 1a and air outlet 1b may be provided in uneven parts provided on the side wall that also serve as positioning. It's okay. Further, it is also possible to cover the side wall with metal foil in advance and tear the metal foil as necessary to form the air inlet 1a and the air outlet lb.

The heater 3a of the heat generating unit 3 that sends warm air into the hollow casing 1 can be used compactly and safely by using, for example, a ceramic heating element. This heat generating unit 3 may be installed at a location away from the hollow rug 2, and hot air may be sent into the hollow rug 2 by a hose. The air sent from the heat generating unit 3 into the hollow rug 2 undergoes heat exchange and is discharged indoors or outdoors from the exhaust unit 4. Further, the exhaust unit 4 may be provided with a suction fan to further improve ventilation efficiency.

In the embodiment shown in Fig. 1, the hollow casings l are laid over the entire surface so that warm air can flow through all the hollow casings l, but there are places where heating is not required, such as the bottom of a dresser or a room. A simple plate material of the same thickness may be placed at the corner of the hollow housing 1, or the airless inlet 1a or the air outlet 1b of the hollow housing 1 may not be connected to those of the adjacent hollow housing l. In addition, in the case of a Japanese-style room, a hollow casing 1 is placed in place of the two or three tatami mats in the center of the room, the heat generating unit 3 is housed in the hollow casing 1 closest to the entrance, and the exhaust unit 4 is placed closest to the entrance. It is also conceivable to have a configuration in which it is stored in a hollow casing l on the exit side and nothing is placed on the floor.

Furthermore, in the embodiment, a combination of a plurality of hollow casings 1 has been described, but it is also possible to use a single hollow casing 1 with a large area.In this case, the inside is appropriately partitioned and the air inlet 1 is
A and a plurality of air outlets 1b may be provided, and a plurality of heat generating units 3 and a plurality of exhaust units 4 may also be arranged. Further, the hollow casing 1 does not have to be square in shape, and may be triangular or a polygon of pentagon or more without any problem.

Furthermore, if a cooling unit is connected in place of the heat generating unit 3, cooling is also possible, and a considerable cooling effect can be achieved simply by blowing air with an air blower. Further, the hollow casing 1 can also be used for soundproofing in the direction below the floor.

[Effects of the Invention] As explained above, the floor heating device according to the present invention is configured such that the rug itself spread on the floor is hollow and warm air is circulated inside the rug, so that comfortable heating can be obtained. It has good heating efficiency and can significantly reduce costs. In addition, the hollow housing made of materials such as synthetic resin has superior durability and water resistance compared to conventional tatami mats, so it can be used hygienically for a long time. Another advantage is that heating can be done locally only where it is needed.
