Description

Hot Air Heater {THE WARM AIR CIRCULATOR}

The present invention relates to a heating device of a plastic house or a greenhouse, and a method of circulating air in a heat exchanger heated by a burner to blow warm air into the greenhouse to propose a heating method.

As a conventional technique for greenhouse heating apparatus, Korean Utility Model Application No. 1991-0006154 (hot air heater) has been proposed, but heat exchanger that transfers heat generated by a burner is made in a round maze so that carbon soot There were a lot of inconveniences to remove. In addition, since the hot air outlet is not configured to be used in the form of a duct, it is not suitable for a large house because one hot air heater must be installed per greenhouse.

In addition, the heat collecting portion coupled to the heat exchanger tube is manufactured by cutting the iron plate in the shape of a box, so that the breakage caused by shrinkage expansion when high heat occurs frequently, there was also a problem that the heat of combustion is not easily circulated.

In addition, Korean Patent Application No. 1999-0060828 (Heater) is proposed, but since liquid is used as a heat transfer medium, the heating time is slower than that of air, which makes it difficult to properly adjust the temperature in a timely manner. Even though the heat preservation time is extended in a manner of generating warm air by heating and heating the heated liquid, the thermal efficiency is inferior.

Therefore, the present invention solves the above problems, the heat efficiency is high, energy can be saved, and the heat collecting unit is configured by a coupling device such as bolts / nuts, and easily detached, hot air that can be easily managed such as cleaning The purpose is to provide a heater.

The present invention consists of the first and second heat exchanger pipes (28a, 28b) of the hot air exchanger made of the same material to achieve the above object, and collects the heat of the burner 1,2,3rd heat collecting tank to supply to the pipe The cover was configured to be easily disassembled by the coupling device 29, such as bolts / nuts.

The hot air heater 10 of the present invention will be described in detail with reference to FIGS. 1 and 2.

First, the configuration of the outer case 17 is a blower 11 is installed on the upper outer case to blow outside air into the case, the control box 12 is installed on the front of the outer case to adjust the power and temperature, A burner 14 coupled to the burner connection 26 of the furnace barrel 22, a combustion sight-seeing window 13 inside the furnace barrel, a hot air discharge duct 16 at the lower periphery of both sides of the outer case, and a rear of the outer case The upper part is comprised by the exhaust cylinder 18 for burner gas discharge | emission.

In addition, the inside of the outer case is coupled to the burner at one end and the other end is the furnace barrel 22 connected to the primary collector 23, the base 21 for supporting the furnace barrel, and the primary and secondary collector 23 And a heat exchanger portion 20 composed of a first heat exchange tube 28b coupled laterally with the 24, and a second heat exchange tube 28a coupled with the second and third heat collecting portions 24 and 25 laterally. do.

Hereinafter, the hot air heater 10 of the present invention will be described in detail for each component.

The cover of the 1st and 2nd heat collecting parts 23 and 24 among the components of the invention is processed by pressing the steel plate with a press, so that there is no damage even in shrinkage / expansion due to high heat, and forms an angle of 15 to 30 degrees. Since the circulating heat can be easily passed, the coupling device 29 such as bolts / nuts is easily coupled and disassembled, so that the combustion can be easily decomposed to remove soot when the combustion rate decreases.

Next, the circulating air flow in the first and second heat exchange tubes 28a and 28b and the heat exchange chamber 30, which are the components of the present invention, will be described with reference to FIG.

The primary heat exchanger tube 28a comprises 8-10 pieces in one set. One end is welded with the primary collector and the other end is welded with the secondary collector and is arranged to match the flow direction to facilitate air circulation as shown in FIG. 3.

The secondary heat exchanger tube 28b comprises 8-10 pieces in one set. One end is welded to the secondary collector and the other end is welded to the third collector and is arranged to match the flow direction to smoothly circulate air as shown in FIG.

The size of the primary and secondary heat exchanger tubes is preferably 300 to 800 mm in diameter, 1 to 1.5 mm in thickness, and 1400 to 1600 cm in length, but the size of the pipe may be changed according to the use and capacity.

In addition, the material is made of copper, which can increase fuel efficiency and save fuel. It is also effective in killing bacteria and has a longer life than steel pipes.

The high thermal efficiency saves energy, extends the life of the boiler, and the user can easily clean himself by easily removing the cover of the 1st, 2nd and 3rd heat collectors.
