Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a radiant heating device used in saunas, industrial drying, etc.

(Prior Art) As a conventional radiation heating device, for example, Japanese Patent Publication No. 62-48767 is known.

However, since this conventional device has only one heat radiating tube, the inlet portion is high temperature and the outlet portion is low temperature, resulting in temperature unevenness and cannot be used when uniform heating is particularly required.

(Problems to be Solved by the Invention) The purpose of the present invention is to solve the above-mentioned conventional problems and provide a radiation heating device capable of uniform heating.

(Means for Solving the Problems) In order to achieve the above object, the present invention has an inlet collecting pipe and an outlet collecting pipe arranged parallel to each other, and the inlet collecting pipe is twisted and bent so that they do not overlap when viewed from the front. The present invention proposes a radiant heating device comprising a plurality of heat radiation tubes connecting a pipe and an outlet collecting pipe, and a burner connected to the inlet collecting pipe and installed across a wall.

(Function) The radiation heating device of the present invention has the structure described in the claims of the utility model registration, and in particular, since it has a plurality of heat radiation tubes, uniform heating is possible with the heat rays from the heat radiation tubes.

The radiation heating device of the present invention has the same configuration as above, and in particular, since the heat radiation tubes are twisted and bent so that they do not overlap when viewed from the front, the uniformity of the heat rays is further promoted.

The radiation heating device of the present invention has the same configuration as above, and in particular, since the heat radiation tubes are provided with apertures, the plurality of heat radiation tubes uniformly radiate heat rays and fully exhibit their function as heat radiation tubes.

The radiation heating device of the present invention has the same configuration as above, and in particular, since it uses collecting pipes, it can easily accommodate an increase in the number of heat radiating pipes.

(Example) The radiation heating device of the present invention will be described below according to an example shown in the drawings.

FIG. 1 shows a radiation heating device according to the present invention, which has a heat radiator 2 installed in a heating chamber 1 such as a sauna room.

The heat radiator 2 has an inlet manifold 3 and an outlet manifold 4 arranged parallel to each other.

The inlet manifold pipe 3 and the outlet manifold pipe 4 are connected by a plurality of heat radiating pipes 5 which protrude upward and are twisted and bent so that they do not overlap when viewed from the front, as is clear from FIG.

The flow path resistance of each of the plurality of heat radiation tubes 5 can be adjusted by a throttle 7.

In the illustrated embodiment, a far-infrared ray paint is applied to the surface of the heat radiation tube 5 so as to radiate far-infrared rays as the heat rays 20.

Said inlet collecting pipe 3 is then connected to the burner 9 via an inlet channel 3a passing through the wall 18.

The burner 9 is completely connected to the heating chamber 1 across a wall 18.
Since it is installed outside, the illustrated embodiment uses a premixed combustion method ignited by an igniter 14.

Furthermore, since the burner 9 (including the combustion chamber 10) is completely installed outside the heating chamber 1, it does not need to be bent.

Said outlet collecting pipe 4 is then connected to an outlet channel 4a passing through the wall 18.

On the other hand, a fan 15 is provided, and the fan 15 is for flowing combustion gas from the inlet manifold pipe 3 to the outlet manifold pipe 4.

Next, in the illustrated embodiment, a temperature sensor 17 for detecting the temperature of the heating chamber 1 is shown.

The action of the radiation heating device of the present invention shown in the above embodiments is as follows.

That is, the combustion gas produced in the combustion chamber 10 of the burner 9 flows from the inlet passage 3a to the inlet manifold 3.

This combustion gas flows through the plurality of heat radiating tubes 5, and since there is a restriction 7, it flows equally into each of the heat radiation tubes 5.

That is, in the one shown in FIG. 1, the pressure of the combustion gas is higher on the left side, so the resistance of the throttle 7 becomes higher toward the left side.

As a result of the above, the temperature of the plurality of heat radiating tubes 5 rises uniformly and the heat rays 20 are radiated.

Furthermore, since each of the heat radiation tubes 5 is twisted and bent so that they do not overlap when viewed from the front, the heat rays 20 are radiated from the heat radiation tubes 5 to the front without waste.

FIG. 3 shows another radiant heating device of the present invention, which has the following features compared to that of FIG.

That is, in the apparatus of FIG. 1, the inlet passage 3a and the outlet passage 4a extend laterally with respect to the heat radiator 2.

On the other hand, in the device of FIG. 3, the inlet channel 3a and the outlet channel 4a extend behind the heat radiator 2.

That is, the difference is that the connecting portion between the inlet passage 3a and the inlet manifold pipe 3 and the connecting part between the outlet passage 4a and the outlet manifold pipe 4 are both moved from the side to the back.

Other than the above-mentioned differences, the apparatus of FIG. 3 is similar to the apparatus of FIG. 1.

(Effects of the invention) The embodiments of the radiation heating device of the invention are as described above, and the effects thereof are listed below.

(1) The radiation heating device of the present invention has the configuration described in the claims for utility model registration, and in particular, since it has a plurality of heat radiation tubes, uniform heating is possible with the heat rays from the heat radiation tubes.

(2) The radiation heating device of the present invention has the same configuration as above,
In particular, since the heat radiation tubes are twisted and bent so that they do not overlap when viewed from the front, the uniformity of the heat rays is further promoted.

(3) The radiation heating device of the present invention has the same configuration as above,
In particular, since the heat radiating tubes are provided with apertures, the plurality of heat radiating tubes radiate heat rays uniformly and fully demonstrate their function as heat radiating tubes.

(4) The radiation heating device of the present invention has the same configuration as above,
In particular, since collecting pipes are used, it is possible to easily accommodate an increase in the number of heat radiating pipes.
