Abstract

Provided by the present inventionly be, a thermal chimney or hot-blast coil pipe are placed in the stove, and its inwall is blown to thermal chimney (pipe) import by small blast fan as the combustion chamber, discharge from outlet the heating back, delivers to the shutter hot blast box in each room to indoor discharging warm braw through heat-resistant hose.Constantly room air is sucked, heats, discharges by the what air blast, so just formed the circulation heating of room air, gradually room temperature is increased.

Effect of the present invention is that the room of the stove of not lighting a fire winter also can be obtained is warm, and its method is simple, economic, practical, need not install and fix pipeline and heat dissipation equipment.

Description

Domestic heating hot-air stove

The structure of this stove and accessory is that (as Fig. 1) is installed in a thermal chimney (2) or hot-blast coil pipe in the stove, and its inwall is as the combustion chamber (7) of stove.By small blast fan, discharge from outlet (9) through the thermal chimney heating then to thermal chimney import (8) air-supply (1), and the shutter hot blast box (5) that leads to each room through pipe (3) is to indoor discharging warm braw.

Because air blast, so just forms the continual circulation heating of room air constantly with room air suction, heating, discharge and gradually room temperature is raise, (the air quantity distribution in each room can be regulated by valve 4).

The effect of this stove and accessory is that the room of the stove of not lighting a fire winter also can be obtained is warm, and its method is simple, economic, practical.Need only not need a small blast fan to get final product by dress fixed-piping and heat dissipation equipment.The available heat-resisting plastic cement pipe of blowing, the position can arbitrarily be moved.

Below in conjunction with accompanying drawing Range structure is elaborated:

This Range structure size is that the coal stove by four honeycomb briquettes of burning provides with reference to (honeycomb briquette is roughly at φ 10-10.5 centimetre, about high 7.5-8 centimetre).As coal cinder quantity and dimensional variations, can change thereupon.

(1), structure of furnace body (as Fig. 2):

With the thermal chimney (O) of steel plate weldering knot or with the hot-blast coil pipe (Q) of steel tube bending, be installed in the center of body of heater, tube inwall (C) is as fire box, tube peripheral filled heat insulating material (E), outer garden with 1 millimeter galvanized iron sheet as outer furnace tube (J), inferior horn is fixed on the chassis (H) with screw, and two fire bars (I) weldering knot is on the internal diameter of thermal chimney bottom.(A, B) is into and out of the air port, (G) is flue, (K) for the stone or metal plate for standing a stove on as a precaution against fire lid, (F) is drawing and pulling type fire door iron plate.

(2) structure of thermal chimney (pipe):

Thermal chimney (as Fig. 4) inwall and on the available 6 millimeter steel plates of going to the bottom, outer wall is with 3 millimeters steel plates weldering knots, each ties import and export with the weldering of φ 40 millimeter molten iron pipes.As can make with steel tube bending hot-blast coil pipe (Fig. 3, Q).For reducing resistance, raise the efficiency, but two-way circle round, two is with connection pipe (A, B), weldering knot in parallel is into and out of the mouth of pipe.Hot-blast coil pipe efficient height, Heating Room is many, but requires blast also high, needs slightly bigger air blast.As when using thermal chimney, the air blast capacity gets final product about 100 watts.

After air duct or coil pipe are manufactured, should carry out more than 1 kilogram/square centimeter and lasting five minutes the water pressure test, ne-leakage is qualified.

(3) furnace bottom and bell dish structure:

Furnace bottom and bell dish can whole sand-cast pig irons, require flat, book scraping, (seeing Fig. 5, Fig. 6 for details).Three risers (L) are in order to supporting upper furnace body on the furnace bottom, and can be incubated, to improve the undergrate blast temperature.Terminal filament hole (H) joins together with screw and outer furnace tube on the footing.The upper end strikes up partnership with front jackscrew (N) the flue base plate (N) and screw (O) card of bell dish.The burner hearth upper end keeps 13 millimeter with the gap (P) of bell, can adapt to the smoke evacuation needs substantially, and hold concurrently and can save coal, as want to strengthen, but bed hedgehopping.

(4) shutter hot blast box (Fig. 7):

The wind box can be used duroplasts, or iron sheet is made the plastics curtain (2) that angle adjustable is equipped with in growth flat-square-shaped (1) front, blast pipe (3) is equipped with at the center at the bottom of the box, and air outlet makes flat trumpet type (4) in the box, by arc wind waveguide plate (5) and window leaf (2) to indoor discharging warm braw.The ivalon of shop 15 millimeters thick in the tank (6) of about 20 millimeters deep is left in wind box bottom in order to room air when dry, to water filling port (7) clear water of annotating, can increase air humidity.The wind box can be hung on the wall with link plate (8).

(5) other business:

1, wind box suspension height should be contour or slightly high with furnace roof, but be difficult for too high.The air-supply blower export should add one section flexible pipe leave stove and accessory (entrance housing, be placed on another chamber also can), and 10 to 15 centimeters above ground level, to keep away dust.

2, can adjust fire door arm-tie aperture control stove fire in the use, during without hot blast, stove fire should weaken.

3, behind inactive hot blast, or the night banking, should make the hot blast box be in open state, (should open) by valvular.

But 4, with the air draft of hot blast box evenly, humidification and attractive in appearance, as save need not, the also available mouth of pipe directly discharges warm braw.

5, the burning of stove and accessory and hot-air system are isolated fully, and the inlet and outlet of hot-air system is open all the time, are perfectly safe so use.

Claims

1, feature of the present invention is: in body of heater [J], a thermal chimney [D] or its inwall of hot-blast coil pipe [Q] combustion chamber [C] as stove is installed.By air inlet [A] air-supply of small blast fan to thermal chimney (pipe), heating.Discharge from air outlet [B] then, lead to the shutter hot blast box (or using the mouth of pipe) in each room by the road to indoor discharging warm braw.

2, by the burning coal stove of claim 1 regulation, it is characterized in that: form by body of heater ［ J ］, bell dish ［ K ］, furnace bottom ［ H ］ and fire door ［ F ］.

3, the shutter hot blast box by claim 1 regulation is characterized in that: the sun blind of angle adjustable are housed in wind box front, are provided with the humidification tank at the bottom of the box, air draft oviduct and arc wind waveguide plate are formed.
