DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating system used for indoor heating and floor heating, and more particularly to a heating system utilizing hot air.

[0002]

Conventionally, as a heating apparatus for both indoor heating and floor heating, for example, a heating apparatus described in Japanese Patent Publication No. Sho 60-7181 is known. The heating device described in this publication uses a single heating heat source, an indoor blower that supplies the heat of the heating heat source onto the indoor floor as hot air, and the heat of the heating heat source is supplied to the floor. A floor blower for supplying warm air to a floor warm air path provided below is provided. The indoor blower and the floor blower are controlled by a common control device. However, the heating device described in Japanese Patent Publication No. Sho 60-7181 has a problem that the heating efficiency is poor because the indoor hot air path and the hot air path below the floor are separate systems.

[0003] Japanese Patent Application Laid-Open No. 4-139325 discloses a heating device for heating by circulating warm air heated by a heat source through a circulation path formed in a ceiling, a wall, or a floor. However, in this heating device, the room is heated by heat radiation from the ceiling, the wall, or the floor, and hot air is not directly supplied to the room, so that the entire room cannot be efficiently and effectively heated. Also, Japanese Patent Laid-Open No.
In the heating device of No. 9325, by providing a joist between the discarded floor plate and the floor finishing material, a circulation path as an in-floor air passage that is bent in a zigzag shape in the floor is formed. Since the formation of the circulation path, such as installation of joists, is performed by construction on site, there is a problem that a large number of man-hours are required to form the circulation path, which leads to an increase in construction costs.

An object of the present invention is to solve such a problem, and a first object of the present invention is to provide a heating apparatus capable of efficiently and effectively heating a room and a floor.
It is a second object of the present heating apparatus to easily form an in-floor air passage through which air for heating passes.

[0005]

According to a first aspect of the present invention, there is provided a heating apparatus, comprising: a heating device provided in a room; a suction port provided in an upper portion of the room; A discharge port provided in the lower part of the floor, a floor air passage provided in the floor and communicating with the discharge port, a descending air path communicating the suction port to the floor air path, and a descending air path from the descending air path. And a blower that blows air to the in-floor air passage.

At the time of heating, the room air is warmed by the heater and rises. By driving the blower, the air in the upper part of the room is sucked into the descending air passage from the suction port. The air is sent to the air passage, and flows into the room again from the discharge port through the in-floor air passage. In this air circulation, the floor is heated by the warm air passing through the in-floor air passage, and the air returned from the in-floor air passage to the room is reused for indoor heating.

According to a second aspect of the present invention, in the heating apparatus according to the first aspect of the present invention, in order to attain the second object, the in-floor air path has a panel having a space layer having its own air path. Or, it is constituted by a panel which has unevenness and forms a space layer which becomes an air passage when it comes into contact with a floor material or a floor base material by the unevenness.

[0008] Thus, the in-floor air passage can be formed by a simple operation mainly for laying panels.

It forms the floor of a room 2.
Also, in FIG. 1, reference numeral 18 denotes a floor structure material such as the above-mentioned upholstery 15, and reference numeral 21 shown in FIG. 1 denotes a heating device such as a fan heater provided in the room 2.

In the upper part of the room 2, a suction port 22 is provided on the surface of the wall 5 near the ceiling 4.
An electric fan 23 as a blower is attached to 22. In the wall 5, a falling duct 24, which is a descending air passage, is provided.
Is installed. The falling duct 24 has an upper end communicating with the suction port 22 and descends downward from the suction port 22.

The warm air convection panel 16 provided in the floor is in the form of a flat plate, but is unitized by providing a plurality of joists 27 between a pair of upper and lower plate members 26. In addition, as a space layer between the plurality of joists 27, an in-floor air passage 28 bent in a zigzag shape as shown in FIG. Note that a portion between the peripheral portions of the two plate members 26 is closed by a side wall 29. And this air passage in the floor
One end 28a of the floor 28 communicates with the lower end of the falling duct 24, and the other end 28b of the in-floor air passage 28 communicates with a discharge port 30 provided in the lower finishing flooring 17 in the room 2. I have.
The discharge port 30 is connected to the falling duct 24 in the room 2.
And located on the opposite side. In addition, the warm air convection panel 16
Furthermore, it is also possible to unitize with the finished flooring material 17.

Next, the operation of the above configuration will be described. In the drawings, the flow of air during heating is indicated by arrows. When heating, room 2 by heating equipment 21
The air inside is warmed and rises. And electric fan 23
, Warm air in the upper portion of the room 2 is drawn as warm air from the inlet 22 into the duct 24, and is sent downward through the falling duct 24. Further, the air flows from the falling duct 24 into the in-floor air passage 28 in the warm air convection panel 16 and flows through the joist 27 of the in-floor air passage 28 into the room 2 again from the discharge port 30. . In this way, the circulation of the air repeatedly passing through the falling duct 24 and the in-floor air passage 28 in the room 2 occurs.
The floor 3 is heated by passing warm air through the in-floor air passage 28. The warm air flowing out of the discharge port 30 is used again for heating the inside of the room 2.

As described above, according to the configuration of the above embodiment,

Further, since the in-floor air passage 28 is formed in the unitized warm air convection panel 16 composed of the plate material 26 and the joist 27, the in-floor air passage 28 is formed by the warm air convection. This can be easily performed by a simple operation mainly including the laying of the panel 16. In addition, the joist 27 allows the in-floor air passage 28 to be formed in a zigzag shape that is substantially uniformly distributed throughout the floor 3, so that the entire floor 3 can be heated substantially uniformly. Further, since the warm air convection panel 16 is provided directly below the finishing floor material 17, the finishing floor material 17 itself forming the floor surface in the room 2 is directly heated, so that the underfloor (soil) is heated. The floor 3 can be heated more effectively than in the case where the

FIGS. 4 and 5 show a modification of the warm air convection panel used in the heating device of the present invention. The warm air convection panel 41 is made of a plate material with irregularities having irregularities on one surface. When the finished flooring 17 is laid on the warm air convection panel 41 with the uneven surface facing upward, the tip surface of the convex portion 43 serving as a joist of the warm air convection panel 41 comes into contact with the finished flooring 17, A space layer serving as an in-floor air passage 28 is formed between the warm air convection panel 41 and the finished flooring material 17 between the mutually independent convex portions 43. As shown by arrows in FIG. 4, the in-floor air passage 28 allows air to pass therethrough, and allows convection of warm air in the present heating device. In the case of the embodiment shown in FIG. 5, the in-floor air passage 28 is formed directly below the finished floor material 17, so that the floor heating effect is further improved.

Further, as shown in FIG. 6, a warm air convection panel 41 having an uneven surface facing down may be laid on a floor base material 46. In this case, the distal end surface of the convex portion 43 of the warm air convection panel 41 is in contact with the floor base material 46, and forms the in-floor air passage 28 between the warm air convection panel 41 and the floor base material 46 between the plurality of convex portions 43. A space layer is formed. The finished flooring material 17 is laid on the warm air convection panel 41.

The warm air convection panel may have irregularities on both sides, and a space layer serving as an in-floor air passage may be formed between the warm air convection panel and the finished floor material and floor base material. . In addition, the shape and size of the convex portion are appropriate, and any shape may be used as long as a continuous space layer can be formed. Further, as a component of the warm air convection panel such as an uneven plate material, an appropriate component such as a resin molded product or a metal component can be used. A variety of other configurations of the warm air convection panel are possible.

Further, the present invention is not limited to the above embodiment, and various modifications can be made. For example, the type of the heating device 21 is not limited as long as it generates warm air. Furthermore, the system of the present heating device can be combined with an air cleaning system, a heat exchange system, or the like.
