The present invention is a long-term period of the hot air blower in the hot air fan to supply a hot air circulated to the normal household heating apparatus or to supply a warm air (hot air) covered at a suitable temperature in a plastic house for growing various gardening crops, such as flowers, vegetables, fruit trees, etc. Wastewater such as soot deposited on the inner wall surface of each heat circulation chamber sealed by use can be removed by the washing water injected through the exhaust pipe, and the wastewater generated after the washing can be easily discharged to the outside of the main body of the warmer.

In particular, the present invention complements the applicant's cabin utility model registration No. 46003 and cabin model registration application No. 91-6154 to improve the efficient cleaning of the inner wall surface of the sealed heat circulation chamber of the hot air blower. .

In general, a hot air fan is equipped with a heating burner on one side and a blower on the other side so that heat generated from the heating burner and air blown from the blower are heat-exchanged with each other to supply the warm air. Each auxiliary cylinder of different cylinders with different circumferential sizes centering on the cylindrical main heating combustor in the center is interconnected by a connection while maintaining proper intervals for the air combustion path to be formed. The heat is caused to rise by each sub-heating combustion part in the main heating combustion part, and the combustion gas is discharged to the outside through the exhaust communication, and when the heat passes through the auxiliary combustion part, the air that is forcedly blown from the blower is warmed through the hot air discharge outlet. It is supposed to supply.

However, when the hot air fan is used for a long time, various harmful gases such as incomplete gas and soot that are not combusted by the combustion gas generated in the heating burner are generated. As it is deposited on the inner wall of the heat sink, it reduces the efficiency of the hot air blower, and as a result, sulfur dioxide is generated, which not only corrodes the heat circulation chamber, but also significantly shortens the life of the hot air blower. It was not possible to rule out the deadly harm.

Accordingly, Utility Model Registration No. 91-6154, filed by the present applicant as a means to solve the above problems, injects the washing water through the exhaust pipe to the heating combustion section of the heat exchange chamber mounted inside the main body to provide the heating combustion section. By washing the inner wall, the soot of various toxic gases deposited on the inner wall is washed out and discharged.Because the washed waste water is discharged through the inside of the main body, it is soot and toxic on the fabric paper deposited on the bottom inner surface of the main body. Wastes containing gases are collected and insufficient to achieve the desired purpose, and the problem of not being able to effectively clean the core heat circulation chamber is exposed.

The present invention was devised to solve all the problems of the prior art as described above, the heat circulation chamber by the repeated use of the hot air exhauster by the mutual heat exchange action of the heat generated in the heating burner and the air blown in the blower Various harmful gases that are repeatedly deposited and corroded on the inner wall of the product can be easily discharged to the outside of the main body after being washed by the washing water injected through the exhaust pipe to extend the service life of the hot air fan and to remove harmful gases to the human body and horticultural crops. The purpose is to provide a warm air heater capable of cleaning the inner wall of the heat circulation chamber.

A feature of the present invention for achieving the above object is that the heating burner and the blower are formed in the movable body so as to be in communication with the combustion chambers formed at both ends, respectively, by the first, second, and third heat circulation chambers. In the warm air heater having the second and air flow passages, the space in the upper portion of the first and second air flow passages 21 and 22 is wider than the space in the lower portion thereof, and the third heat circulation chamber 13 is provided. The discharge pipe 16 having a valve 17 is installed to communicate with the waste collection collecting passage 15 protruding outward to the lower center of the communication.

Hereinafter, the hot air heater according to the present invention will be described in detail with reference to the accompanying drawings.

In the central part of the main body 1, there is a cylindrical combustion chamber 10 mounted with a heating burner 2 on one side and an open side on the other side, and the first thermal circulation chamber 11 and the second thermal circulation chamber 12 on the outer side thereof. ) And the third heat circulation chamber 13 are spaced at appropriate intervals so that the first and second air flow passages 21 and 22 are formed and communicated with each other by the connection pipes 18, 18 'and 19, respectively. In particular, the first heat circulation chamber 11 and the second heat circulation chamber 12 communicate with each other at the upper and lower sides, and the second heat circulation chamber 12 and the third heat circulation chamber 13 are provided only at the lower side. The connecting tube 18 ′ which communicates with the first heat circulation chamber 11 and the second heat circulation chamber 12 at a lower side thereof may communicate with the second heat circulation chamber 12 and the third heat circulation chamber 13. The connecting pipes 19 communicate with each other and are not aligned on the same vertical line but are staggered and staggered.

In addition, the first and second air flow passages 21 and 22 formed between the respective heat circulation chambers are formed with a heat circulation chamber so that the upper space is slightly wider than the lower space, and the lower end of the third heat circulation chamber 13. In order to protrude outward, the wastewater collecting conduit 15 is provided, and the discharge pipe 16 having the valve 17 is in communication with each other. In addition, the support 6 is fixed in parallel to the lower part of the main body 1, and the wheels 7 are respectively condensed on both sides.

The operating state of the present invention thus constructed is shown in FIG.

When the heating burner 2 is operated, combustion heat exits the combustion chamber 10 and enters and circulates in the first heat circulation chamber 11, and the second heat circulation chamber 12 is connected to the second heat circulation chamber 18 through 18 ′. Inflow circulation into the third heat circulation chamber 13 through the connection pipe 19 again, the combustion gas is circulated with the heat of combustion and discharged to the outside through the exhaust pipe (14).

At this time, the cold air forcedly blown from the blower 4 passes through the air passages 21 and 22 between the first, second, and third heat circulation chambers 11, 12, and 13 heated by the combustion heat. When passing through it is changed into hot hot air, hot air is supplied to the circulation through the hot air outlet (5) to the duct (8) installed inside the plastic house.

However, when the hot air fan is operated for a long time, a part of the combustion gas, unburned gas, and soot generated in the heating burner 2 is not discharged to the outside, and is stuck to the inner wall of each heat circulation chamber, especially the heating burner. A large amount of vapor is deposited on the inner wall surface of the third heat circulation chamber 13 including the exhaust tube 14 of which thermal power and wind power are somewhat insignificant, thereby significantly reducing the performance of the hot air fan, and moisture and moisture generated in the greenhouse. By reacting and oxidizing each circulation chamber, not only shortening the life span, but also generating sulfurous acid gas, which causes fatal damage to human body and horticultural crops.

Therefore, in order to reduce such damage, it is fundamentally required to keep the interior of the heat cycle chamber clean. As a means for maintaining the clean state, water is injected into the interior to be washed. Washing water is to be able to efficiently discharge the waste water generated after washing various wastes to the outside of the main body.

That is, in FIG. 4, the state of washing the interior of the thermocycle chamber is illustrated, and the washing water is injected through the exhaust tube 14, and the injection method arbitrarily executes various methods such as a hose or an injection or injection method. When the washing water is injected, the washing water washes various foreign matters deposited on the inner wall surface of the third heat circulation chamber 13 to be collected in the waste water collecting passage 15 and to the outside of the main body of the hot air blower 1 through the discharge pipe 16. Drains easily

This cleaning method is most easily performed, and the cleaning time is short, so it can be cleaned from time to time.

However, when the hot air fan is used for a long time, various wastes are added to the inner wall surfaces of the first and second heat circulation chambers 11 and 12, so that the valve 17 installed in the middle of the discharge pipe 16 is closed to remove them. Then, the washing water is injected until it is completely filled inside each thermocycling chamber, and after a while, it is delayed a while, and when the waste is judged to have been completely peeled off and diluted from the inner wall by the washing water, the valve 17 is opened. The inner wall can be cleaned.

However, since this requires some time, it is effective to carry out when cleaning inside the hot air heater is required.

In this way, if the thermal circulation chamber is cleanly cleaned by washing water, it can be used while maintaining the efficiency of the hot air fan and can be used for a long time because it prevents corrosion, and it can prevent damage to human body and horticultural crops by sulfur dioxide. It is useful.
