Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a radiant heater device used for drying, food processing, and various other heating purposes.

[Prior art and issues] Since there was no radiant heater used for each of the above-mentioned purposes that was versatile enough to be installed according to the various conditions of the object to be heated, it was necessary to design and produce it each time. The production costs were high.

In addition, as a radiation burner, for example, there is one described in Publication No. 16034 of 1971, which is
Since it is a burner, that is, a combustor, and uses a pre-mixing method, it requires a gas pipe, an air pipe, an exhaust pipe, and a mixing flame holding area surrounded by a mixing plate. , the burner combustion chamber shall be constructed of refractory material. In other words, each element necessary for combustion must be configured, which makes the device complex, and the shape and configuration are fixed, making it difficult to adapt to the shape and size of the object to be heated. There are some tasks that cannot be done. This invention provides a compact radiant heater with small capacity.
It can be installed in any way depending on the purpose and situation of the object to be heated.

[Means for solving the problem] A partition member is installed inside the radiator having a spherical radiant part, and the front part is divided into a heating chamber and the rear part is divided into an insulation chamber, and one end of the hot air introduction pipe is connected to the insulation chamber. The hot air outlet tube is penetrated and protruded into the heating chamber, and a hot air outlet is provided in the protruding part, and the hot air outlet tube is installed in the hot air introduction tube coaxially therewith and is made to protrude beyond the hot air introduction tube,
It has a configuration in which a spherical hot air guide member is installed around the outer periphery of the protrusion.

[Function] The hot air effectively heats the spherical radiant portion by the spherical hot air guide plate, and the spherical radiant portion heats the object to be heated over a large radiant range. Since a heat insulating chamber is provided on the rear side of the heating chamber by a partition member, the rear side is not heated and can be installed at any location.

[Example] Reference numeral 1 denotes a radiator having a spherical radiant portion 2 . A partition member 3 is installed inside the radiator 1 to partition the front into a heating chamber 4 and the rear into a heat insulating chamber 5 filled with a heat insulating material or the like. Reference numeral 6 denotes a hot air introduction pipe, one end of which passes through the heat insulating chamber 5 and projects into the heating chamber 4, and a hot air outlet 8 is provided in the protruding portion 7. Hot air introduction pipe 6
A spherical hot air guide member 10 is installed inside the hot air introduction pipe 7, coaxially with the hot air introduction pipe 6, and protruding from the hot air introduction pipe 6, and around the outer periphery of the protrusion 7'. The heat insulating chamber 5 may be appropriately filled with a heat insulating material, and the hot air blowing holes 8 may be formed so as to blow out in the axial direction. Further, the radiation part 2 may be provided with radiation promoting means to increase the radiation effect.

[Function] In the above configuration, a hot air generation source (not shown)
The hot air introduced from the radiator passes through the hot air introduction pipe 6 and is ejected from the ejection hole 8 into the heating chamber 4, is guided by the guide member 10 as indicated by the arrow in the figure, heats the radiant section 2, and enters the hot air outlet pipe 9. It is emitted from the radiator 1. In this case, the hot air is guided by the spherical hot air guide plate 10 to uniformly heat the radiant section 2 throughout, and since the radiant section 2 is spherical, the radiant range is widened. Further, since the rear of the radiator 1 is configured as a heat insulating chamber 5, overheating of the rear portion of the radiator 1 can be avoided.

[Effects of the invention] Since the present invention is as described above, there is no need for any components necessary for combustion, and it can be made entirely of metal, which is easy to manufacture. The radiant section has the advantage that effective heating can be carried out over a large radiant range.
