The figure I is the domestic multi-purpose gas or coal burning drying box schematic diagram, and by casing X, thermoconverter RZ, combustion furnace RIS(sees the figure II) and the automatic controller composition.

X surface size 1500 * 600 * 400mm, the thick 20-30mm of case shell, internal layer makes with the higher fineness aluminium of thick 0.3mm skin, and cladding material is not limit, the most handy plastics.The intermediate layer is the heat insulation foamed plastic of thick 20-30mm.

With reference to the figure I, (1) is sizable steam vent.(2) clothing suspension can suspend 5 adult's western-style clothes or a double sheet in midair.(4) pendulous device, it can make (2) swing; Driven by motor can not swung with manual operation when having electricity, and its function is swung the clothing of suspension in casing, makes circulation in the casing air.

The figure II is thermoconverter RZ profilograph (i.e. figure I A-A ' section).(4) hot change-over panel makes with steel plate or cast iron, some copper sheets of end face weldering.(5) dividing plate makes with the 0.6-0.8mm aluminium sheet, its separated combustion waste gas and heated air; (6) air flow control plate makes with the 0.6-0.8mm aluminium sheet, and its effect is that the air that is admitted to is contacted with radiating copper sheet on (4) to greatest extent; (7) hot gas dispersion plate, the 0.6-0.8 aluminium sheet makes, and several apertures are arranged on it, and its effect is that the high temperature air flow point that is flowed out by the S chamber is loose; (8) the temperature homogenisation plate is used 0.6-0.8mm, and aluminium sheet makes, and countless apertures are arranged on it, and its effect is to make hot air temperature and the flow velocity homogeneous that is flowed out by the J chamber; (9) blast pipe, makes with aluminium by 4-5 side by side; (10) asbestos insulation plate, thick 5-10mm; (11) automatic controller (seeing the figure III for details): (12) thermoconverter shell, 0.6-0.8 aluminium sheet; (13) air feed chamber wall, the 0.6-0.8mm aluminium sheet; (14) air-flow direction; (15) exhaust gas flow direction; (16) guard shield is made with the chromium plating thin wire gauze, prevents that clothing from falling on (8); The FJ-blower fan, electronic, hand when not having electricity; The RIS-combustion furnace, it can be the fire coal steam stove, liquefied gas furnace dyes steam stove, coal dust ball stove, honeycomb briquet stove etc.; R chamber-combustion chamber, G chamber-air feed chamber, the burnt gas afterheat makes G chamber absorption of air through G chamber wall; Z chamber-dust-collecting cavity, storage waste gas dirt; S chamber-high temperature chamber, the air of being sent into by blower fan FJ heats in this chamber, finishes the heat conversion; J chamber-temperature homogenisation chamber, thermal current is at this chamber convection current, temperature homogeneous.

Finishing heat conversion and drying clothes process is: RIS work is passed to hot change-over panel (4) to main heat energy, and the burnt gas that produces in the R chamber enters the Z chamber along direction shown in (15), and useless dirt sinks, and waste gas is discharged.The high-temp waste gas that comes out in the R chamber will be passed to G chamber wall (13) to most of heat energy, and blast pipe (9) and dividing plate (5) are passed to the air that is used for drying clothes again by them, reduce the thermal losses that causes because of the waste gas discharge.Blower fan FJ outside air through the G chamber and airduct (9) send into the S chamber, absorbed partial heat energy on the way, temperature is existing to raise.Because hot change-over panel (4) temperature is up to 200-400 ℃, and has fin, S chamber air is heated to more than 100 ℃, and the volume several times that also thereupon expand enter the J chamber under the promotion of blower fan.Because the effect of air flow control plate (6) and hot gas dispersion plate (7), the hot gas flow direction is as (14) indication, under temperature homogenisation plate (8) effect, convection current takes place in hot gas in the J chamber, pass the hot air temperature homogeneous of temperature homogenisation plate (8), remain in the 60-80 ℃ of scope, flow into then among the casing X.Enter the hot gas of casing X, vapour pressure is extremely unsaturated, and (temperature has raise because air is heated the back, volumetric expansion, but moisture does not increase), make the wet wash moisture content rapid evaporation that hangs in the casing, the swing of pendulous device (3), make circulation in the air among the casing X, evaporation is further accelerated, and vapour pressure raises, near saturated, under the promotion of bottom blower fan FJ, discharge outside the case by steam vent (1).The extremely undersaturated hot gas of vapour pressure is sent constantly into casing, and the nearly saturated air of vapour pressure is constantly discharged, and makes the clothing oven dry.

With reference to the figure III, the figure III is the structural representation of the automatic controller (11) in the figure II.(11-1) heat transfer bar is made by copper or aluminium, and an end is tubular, and wherein rank has piston sleeve (11-2).Piston sleeve (11-2) end has the end, and the other end inserts piston boit (11-3), and brake fluid and air are housed in the piston sleeve.Be close tolerance seal between piston sleeve and the piston boit, but can move to also have oil sealing between the two.(11-4) be spring; (11-5) be the combustion furnace switch, it also can directly be promoted by piston boit (11-3); CA, DE are drive links, and tooth is arranged on the DE; C is a run-on point.

Automatic controller can be controlled combustion furnace switch (11-5) size, guarantees combustion furnace RIS(figure II) to determine the speed harmonious combustion.Realize that the automatic control process is as follows: heat transfer bar one end places high temperature S chamber (figure II).When the burning excess of combustion furnace, S cavity temperature superelevation, excessive heat is passed to piston sleeve (11-2) by heat transfer bar (11-1), and air expands in the sleeve, promotes piston boit (11-3) and moves, and CA rotates, and DE moves, and drives combustion furnace switch (11-5) and turns down.When the S cavity temperature was low, air shrank in the piston sleeve (11-2), under spring (11-4) effect, and the CA backward rotation, combustion furnace switch (11-5) leaves greatly.As long as change the length ratio of CB and BA, can reach debugging purpose during debugging.In addition, on automatic controller, also timing means can be installed, reach complete automatic control purpose.

This drying baker once can be dried adult's clothes 4-5 spare, and perhaps double bed is by single bed, preliminary test, and the double cotton sheet after dehydration of oven dry under the 3-8 ℃ of temperature condition only needs 0.8-1 small-sized honeycomb coal.When not drying by the fire clothing, cabinet space can be hung 5-6 spare western-style clothes; Combustion furnace can be used to heating or works as the cooking stove and use.
