Description

[Detailed Description of the Invention] The present invention relates to a hot air floor heating device.

Conventionally, as a floor heating system, as shown in Fig. 8, a hot air fan d is blown through a duct c into a hollow floor panel a having a large number of blowing holes b, b, ... on an upper wall surface _a1 . A so-called hot-air type heating system is known in which heating is performed by connecting outlets (not shown) and blowing hot air from each blow-off hole b of the floor panel a. In this type of hot air floor heating system, a plurality of grooves e, e,... are formed on the upper wall surface _a1 of the floor panel a, and the outlet holes are formed on both side wall surfaces of each groove groove e. By providing the holes b, b, ..., it is possible to prevent each blow-off hole b from being blocked by dirt etc. attached to shoes, and to blow hot air through the blow-off holes c without applying vertical inertia force. The air is blown out almost horizontally from the heating element to suppress the rise of warm air to a gradual degree, thereby increasing the heating effect (see Japanese Utility Model Publication No. 56-56518).

However, in the conventional device, each concave groove portion e
Sufficient consideration has not been given to the mutual positional relationship of the blow-off holes b, b, ... on both side walls of the
Because the blow-off holes b, b... were provided facing each other in a direction orthogonal to the length direction of the grooved groove portion e solely from the viewpoint of workability, air was emitted from both the blow-off holes b, b facing each other. The warm air collides with each other and flows upward, making it impossible to sufficiently suppress the rise in warm air. In addition, since warm air does not accumulate well on the surface of the floor panel a, it is necessary to provide many concave grooves e for air outlet holes in order to heat the entire surface of the panel a, which makes the processing more complicated and However, there were problems in that it lacked practicality, such as its strength becoming weak and making the scaffolding unstable during use.

In view of this, the present invention is designed so that the hot air blown out from the respective blow-off holes on both side wall surfaces of the groove groove as described above flows almost horizontally along the surface of the floor panel without interfering with each other. The purpose of this invention is to improve the hot air heating effect by sufficiently suppressing the rise in warm air, and to reduce the required number of grooves and improve workability.

Therefore, the configuration of the present invention is such that, in a hot air floor heating device comprising a hollow floor panel and a hot air fan that supplies hot air into the floor panel, grooves are formed in the upper wall surface of the floor panel. However, a large number of blow-off holes for blowing out warm air are provided on both side wall surfaces of the concave groove section so as to be staggered with each other, thereby preventing the warm air blowing out from the blow-off holes on both side wall surfaces from colliding with each other. .

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 1 shows a hot air floor heating system according to the present invention, in which 1 is a hot air fan, and inside a casing 2 of the hot air fan 3, an oil burner 4, a heat exchanger 5, etc. are arranged. It is set up. In addition, a suction port 6 is provided at the bottom of the back surface (front side in FIG. 1) 2a of the casing 2, and a suction port 6 is provided at the bottom of the front surface (back side in FIG. 1) 2b and one side 2c of the casing 2. An air outlet (not shown) is provided. The air sucked in from the suction port 6 by the operation of the blower fan 3 is heated via the heat exchanger 5 by combustion in the oil burner 4, and is converted into warm air from the blowout port to a series of floor panels described below. 14.

Further, 7 is a floor panel unit configured to be connectable in series, and the floor panel unit 7 includes:
As shown in FIGS. 2 to 5, a panel body 8 in the form of a hollow panel with both end faces in the connection direction open;
The panel body 8 includes a rectangular cylindrical duct 10 disposed in the connecting direction of the central portion of the hollow portion 9 of the panel body 8. A plurality of outflow holes 11, 11, for example, four outflow holes 11, 11, . A well-known adjustment device such as a damper is provided to adjust the opening area. on the other hand,
The upper wall surface 8a of the panel main body 8 is provided with a plurality of grooves 12, 1, for example, five grooves, extending in the connection direction.
2, .
A, 12a have a large number of blowing holes 1 that blow out hot air.
3, 13,... are drilled so that they conflict with each other. Here, as the dimensions of each part of the floor panel unit 7, for example, the length of the panel main body 8 in the connection direction is
1800mm, the end face width is 900mm, and the height is 110mm, the adjacent grooves 12, 12, 12, .
12 interval is 206.5mm, the groove width of each groove part 12 is 24mm,
The groove depth was set to 21 mm, and blow-off holes 13 with a diameter of 9 mm were bored at a pitch of 30 mm on each of the side wall surfaces 12a, 12a of the groove portion 12.
The blow-off holes 13 on one side are made to face each other at an intermediate position between the blow-off holes 13, 13 on the other side, so that they conflict with each other.

Thus, a plurality of floor panel units 7, for example, four in FIG. 1, are connected in a series with their respective ducts 10 communicating with each other to form a series of floor panels 14, and the floor panels at one end in the connection direction are One end of the duct 10 of the unit 7 is bent in the horizontal direction so as to face the front outlet of the hot air fan 1, and the tip of the bent part 15 is connected to the front outlet of the hot air fan 1. (In this case, warm air fan 1
(The side air outlet is blocked). On the other hand, the other end surface of the floor panel unit 7 on the other end side in the connection direction and the other end of the duct 10 of the floor panel unit 7 on the other end side are closed by a closing member (not shown). Furthermore, the outflow holes 11, 11, . . . of the ducts 10 in each of the units 7, 7, . Note that 16 is a partition plate provided between the outflow holes 11 and 11 of the duct 10 in the hollow part 9 of each panel main body 8, and the hollow part 9 of each panel main body 8 is separated from the three partition plates 1.
6, 16, and 16 are divided into four equal parts in the connection direction.

Therefore, in the above embodiment, the hot air fan 1
The hot air blown out from the front air outlet flows through the duct 10 of each floor panel unit 7, and flows through each outlet hole 1 of the duct 10 in each floor panel unit 7.
1 to the panel body 8 and the hollow part 9 is dispersed.
Thereafter, the warm air in the hollow portion 9 of each panel body 8 is blown out almost evenly from each blow-off hole 13 on the upper wall surface 8a of the panel body 8, and as a result, the series of floor panels 1
Floor heating is performed over a long range of the total length in the connection direction of No. 4.

At this time, each of the blow-off holes 13 is connected to both side wall surfaces 12a, 12 of the concave groove portion 12 of the upper wall surface 8a of the panel main body 8.
Since they are provided so as to be offset from each other, the hot air blown out from each of the blow-off holes 13 is directed almost horizontally to the blow-off holes 13 on the opposing side wall surface 12a without being subjected to vertical inertial force. Since the warm air flows along the upper wall surface 8a of the panel main body 8 without colliding with the warm air from the panel main body 8, the warm air is easily retained on the upper wall surface 8a of the panel main body 8, and this is compatible with the fact that the attraction of cold air caused by the rise of warm air can be prevented. This allows you to effectively heat your feet. Furthermore, it goes without saying that there is no concern that the blow-off holes 13 will be blocked by dirt or the like adhering to shoes.

Moreover, since the warm air is well retained on the upper wall surface 8a of the panel main body 8, it is not necessary to provide many concave grooves 12 for the blow-off holes in order to evenly heat the entire upper wall surface 8a of the panel main body 8. As a result, the panel main body 8 can be easily processed, sufficient strength can be ensured, the scaffolding during use becomes stable, and safety can be improved.

FIG. 6 shows an example of the arrangement relationship between the warm air fan 1 and each floor panel unit 7, and FIG. An example is shown in which the front outlet of the hot air fan is arranged on one side in the connection direction of 7, 7, .... 6th
Figure b shows the series of floor panel units 7, 7,...
An example is shown in which the hot air fan 1 is disposed on one side in the connection direction by connecting one end of the duct of the floor panel unit 7 on one end side to the side outlet of the hot air fan 1.

Further, FIG. 6c shows the floor panel unit 7 at one end in the connection direction of the four floor panel units 7, 7, . . . connected in series and the side outlet of the hot air fan 1 in detail. An example is shown in which the side outlet of the warm air fan 1 and one end of the duct of the floor panel unit 7 on one end of the connection direction are connected via an auxiliary panel 18 having a curved duct 17 that communicates with the side outlet of the hot air fan 1.

Furthermore, FIG. 6d shows an arrangement example combining the above-mentioned FIGS. 6a and 6c, in which two connected floor panel units 7, 7 are arranged adjacent to each other, One side of the one connected floor panel unit 7, 7 in the connection direction is connected to the front outlet of the hot air fan 1, and the side outlet of the hot air fan 1 and the other connected floor panel unit 7, 7 are connected to each other. Auxiliary panel 1
They are connected via 8. In this case, the heating range can be expanded not only in the direction in which the floor panel units 7 are connected, but also in the orthogonal direction.

In the above embodiment, a series of floor panels 1 is constructed by connecting a plurality of floor panel units 7, 7, . . . to each other.
Although the explanation has been made regarding the warm air type floor heating system constituting No. 4, it goes without saying that the present invention can be similarly applied to a hot air type floor heating system that uses a normal single floor panel.

As explained above, according to the present invention, the hot air blown out from each outlet can be made to flow along the surface of the floor panel without colliding with each other, so that the retention of warm air on the surface of the floor panel can be effectively prevented. In addition to greatly improving the heating effect, the number of grooves for the outlet holes can be reduced.
It is possible to improve workability and safety during use.
