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 object of the present invention is to solve the above-mentioned conventional problems and to provide a radiant heating device that can perform uniform heating and does not cause the risk of building walls becoming hot.

(Means for Solving the Problems) The present invention aims to achieve the above objects by: 1. An inlet collecting pipe and an outlet collecting pipe arranged parallel to each other, and an inlet which is twisted and bent so that they do not overlap when viewed from the front. A plurality of heat radiating tubes connecting a collecting pipe and an outlet collecting pipe, a combustion chamber formed inside a wall at an inlet portion of the inlet collecting pipe, and positioning for insertion into the combustion chamber through the wall. A radiant heating device 2 comprising a burner and a combustion chamber according to claim 1, wherein a combustion chamber is formed in an inner cylinder that is an inlet part of an inlet collecting pipe and protrudes from the burner side inside the wall. This paper proposes a radiant heating device.

(Function) (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. Become.

(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 combustion chamber is formed inside the wall at the entrance of the inlet collecting pipe, there is no risk of the building wall becoming hot.

(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.

Next, at the inlet part of the inlet collecting pipe 3, the wall 18
A combustion chamber 10 is formed inside.

The combustion chamber 10 has a burner 9 extending through the wall 18.
is positioned for insertion.

Further, the combustion chamber 10 is insulated by a heat insulating material 13 to prevent the temperature of the wall 18 from rising.

On the other hand, in the illustrated embodiment, the burner 9 uses a premix combustion method in which it is ignited by an igniter 14.

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 used to flow combustion gas from the inlet manifold 3 to the outlet manifold 4 via the heat radiation tube 5.

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 by combustion in the burner 9 flows into the inlet manifold pipe 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.

In other words, when the burner 9 inserted and positioned through the wall 18 is located close to the heat radiation tube 5 as shown in the figure, the flame directly flows into the heat radiation tube 5 on the closer side, and the plurality of heat radiation tubes 5 mutually interact. Temperature unevenness will occur.

To prevent this, an inner cylinder 3a made of a heat-resistant material such as stainless steel is installed inside the inlet collecting pipe 3 as shown in the figure.
may be made to protrude from the burner 9 side.

In this case, the combustion chamber 1 will be formed within the inner cylinder 3a.

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 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.

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 combustion chamber is formed inside the wall at the entrance of the inlet collecting pipe, there is no risk of the building wall becoming hot.
