Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 2 to 6, the warm air dryer for use with wood as a fuel according to the present invention includes a combustion chamber 101 and a main body 100 for burning wood, And a water supply unit 130 for supplying or circulating water into the main body 100. The water supply unit 130 includes a fuel supply unit 110 for supplying fuel to the main body 100, an external flue 120 for discharging the smoke generated in the combustion chamber 101 to the atmosphere,

The main part constitutes an inner flue 121 connecting the combustion chamber 101 and the outer flue 120 in order to discharge the flue gas generated in the combustion chamber 101. The inner flue 121 serves as a passage for discharging flue gas generated in the combustion chamber 101 and induces heat conduction in the process. And is located inside the casing 102 of the boiler body 100 so that heat can be directly transmitted to the jacket 103. Referring to FIG. 3, the combustion chamber 101 is installed vertically upright on the upper portion of the combustion chamber 101.

A casing 102 enclosing the outside of the combustion chamber 101 and a jacket 103 formed between the casing 102 and the outer wall of the combustion chamber 101 are formed. Referring to FIG. 3, the jacket 103 includes an outer space of the combustion chamber 101 and the casing 102, and an upper space of the combustion chamber 101. The jacket 103 is a space for storing water and causing heat exchange with the combustion heat in the combustion chamber 101 or forming a hot air flow, and the water is heated by heating and heat exchange in the combustion chamber 101, A hot air flow is formed through the combustion heat generated from the combustion chamber 101.

Then, a tank 104 for supplying and replenishing water into the jacket 103 is constructed. The tank 104 is a means for supplying water with water pressure through a water supply line 126 and filling water into the jacket 103 through a water supply port 104a in a natural dropping manner.

An air inflow airflow 105 is provided outside the casing 102 to introduce outside air into the jacket 103. The air inflow airflow 105 has a volume area for allowing a sufficient amount of air to flow in and an inlet port portion communicating with the casing 102 so as to prevent the water filled in the jacket 103 from overflowing on the basis of the atmospheric pressure water surface, 102).

An air exhaust airflow 106 connected to be in communication with the jacket 103 is configured to discharge the air flowing in the jacket 103 at a position away from the air inflow airflow 105. [

It is preferable to place the air discharge windings 106 on the lower side of the casing 102 so as to include most of the jacket 103 space regions as the air flow space in a state in which the water in the jacket 103 is removed, (Not shown) for discharging the air so as not to overflow at the atmospheric pressure water level when the water is filled in the jacket 103 is relatively higher than the height of the upper space of the jacket 103.

3, an inlet of the air inflow airflow 105 is located on the upper side and an outlet of the air discharge airflow 106 is located on the lower side, on the contrary, with reference to the casing 102.

4, the external flue 120 and the internal flue 121 are divided by the boiler main body 100 and include a water pipe 122 installed around the internal flue 121 do.

Further, a drain valve 123, which is in communication with the jacket 103, is provided for discharging the water filled in the jacket 103 to empty the internal space.

The tank 104 is located above the boiler body 100 to store water supplied from the outside and induce natural drop of water to supply water into the jacket 103.

The tank 104 includes a water supply line 126 for supplying water supplied from the water source and a floater 124 for interrupting the water supply to the water supply line in the water supply line 126 in accordance with the level of the supplied water. And a drain 125 which flows out when the water surface to be filled in the tank 104 overflows.

The water supply and interruption by the floater 124 is a well-known method for opening and closing the valve through the knitting action, so a detailed description is omitted. The condition in which the water filled in the tank 104 is at an appropriate water level is that the space in the jacket 103 of the boiler body 100 is filled with water and the replenishment is stopped. When the water level is lowered, the water supply is resumed. When the water level is filled with the full water level, the floater 124 floats up in the tank 104, and the water supply stops due to the valve intermittency.

The reason why the water level in the jacket 103 rapidly fluctuates is when water in the jacket 103 is drained through the outlet 123a. When the discharge port 123a is connected to the heating pipe circulating through the room and used as boiler hot water, the water level of the jacket 103 hardly fluctuates.

Another variation cause is when the jacket 103 is emptied and used as a hot air dryer, and the water in the jacket 103 is discharged through the drain valve 123. At this time, if the drain is performed while the water supply side water supply valve (not shown) for supplying water through the water supply line 126 is closed in advance, all the water remaining in the tank 104 and the jacket 103 is returned to the atmospheric pressure reference It is exhausted altogether.

One side of the water supply line 126 is connected to a water supply line 126 so that water can be supplied from the water supply line 126 and an internal cylinder 121 for discharging combustion gas to heat- And a water pipe 122 is provided so as to cause heat exchange. The heated water which has been heat-exchanged through the water pipe 122 can be used as washing water, washing water, general hot water, and the like.

7, a blower 127 for forcibly sucking the outside air into the jacket 103 is installed in the air inflow wind pattern 105 provided on the outside of the casing 102, So that air heated by the heat generated in the air exhaust vent 106 can be accelerated and exhausted.

The air characteristics heated and accelerated while flowing in the jacket 103 are warm air influenced by the ignition temperature of the combustion chamber, the volume of the jacket, the air retention time, and the atmospheric temperature atmosphere at the end outlet.

Such hot air can be used for various purposes such as indoor air composition for cultivating crops, warm air composition for warming indoor air, dryer for drying agricultural and marine products (eg, pepper, aquatic products), and industrial field.

Reference numeral 102a denotes a "heat insulating material" for inspecting the outside of the casing 102. [ And 104a is a water supply port installed in the tank 104. [ Reference numeral 111 denotes a " hinged handle " 112 is a door for discharging ashes. Reference numeral 113 denotes a 'cylinder' installed to open and close a door 112 for discharging ashes. Reference numeral 114 denotes a tuyere in which air flows into the combustion chamber 101. Reference numeral 128 denotes a "base" for supporting the main body 100 on the ground, and reference numeral 129 denotes a height adjuster for adjusting the base height. 140 is a blowing fan that blows air into the combustion chamber.

The function of the hot-air dryer combined with the heating boiler using the wood fuel according to the present invention will now be described in detail.

The present invention can be used as a heating boiler or a hot air dryer. (Not shown) circulating the room through the outlet 123a and opening a valve (not shown) provided in the water supply line 126 to supply water into the jacket 103 do.

At this time, the supply of water falls into the jacket 103 through the water supply port 104a to fill the jacket 103 while filling the tank 104 with water pressure when the valve of the water supply line 126 is opened.

When the jacket 103 is filled with water, the floater 124 of the tank 104 floats, closing the valve and stopping water supply.

When the wood is put into the combustion chamber 101 and ignited, the temperature of the combustion chamber 101 is increased by the combustion heat, and the heat increases the temperature of the water filled in the jacket 103.

The combustion gas generated in the combustion process is discharged through the inner flue 121 as shown in FIGS. 4 and 5, and is discharged into the hot water by heat-exchanging the water flowing along the water pipe 122 in this process. The hot water discharged through the water pipe 122 can be used for various purposes as hot water for indoor heating which is discharged through the discharge port 123a and as hot water separately.

The water pipe 122 is arranged in a manner to surround the inner flue 121 where the hot waste combustion gas is exhausted in order to utilize heat energy efficiently and to have a high heat exchanging area, thereby exhibiting good heat exchange performance.

The supply of water for filling the jacket 103 for heating is performed by opening the valve but the water level adjustment is automatically stopped when the water level reaches the limit level by the float 124 as shown in FIG. And the water overflowing the tank 104 is discharged to the drain port 125, so that the overflow of the tank 104 is prevented.

On the other hand, when the present invention is used as a hot air dryer, the valve of the water supply line 126 is shut off as shown in FIG. When the drain valve 123 is opened, the water filled in the tank 104 and the jacket 103 is discharged through the drain valve 123. At this time, the outlet 123a valve connected to the heating pipe is closed.

When the water that has filled the tank 104 and the jacket 103 passes through the drain valve 123 over time, the internal space of the jacket 103 becomes empty space.

The temperature of the combustion chamber 101 rises and the air flowing through the jacket 103 flows directly or indirectly to the radiant heat radiated from the outer wall of the combustion chamber 101. In this case, The temperature rises with contact.

When the blower 127 is operated to accelerate the warmed air in the jacket 103, the outside air is sucked through the air inflow airflow 105 to introduce new atmospheric air into the jacket 103, (106) while rapidly mixing with the flowed air heated in the air outlet (103).

At this time, the air discharged through the air exhaust airflow 106 is dried air whose temperature has been raised, and escapes with a warm air due to the movement pressure of the follower 127.

Such warm air can be used for drying or warm air can be used for indoor heating air conditioning. The air characteristics accelerated and discharged by the blower include the ignition temperature of the combustion chamber, the volume of the jacket, the air staying time, And is influenced by the atmospheric temperature atmosphere in the air.

Warm air can be used for a variety of purposes such as indoor air composition for cultivation of crops, air conditioning for indoor heating, drying for drying agricultural and marine products (eg, pepper, aquatic products), and industrial field.

The present invention is not limited to the embodiments described. And can be modified and modified without departing from the gist of the present invention. Modifications and variations are included in the technical scope of the present invention.
