Abstract

A hot-air cylinder is a novel warming device, and the hot-air cylinder is arranged on the common domestic stove for supply hot-air without influencing the original purposes of the stove. The utility model is characterized in that the hot-air cylinder is double-layer, and an inner cylinder and an outer cylinder form an interlayer. The inner of the interlayer is provided with spirality heat dispersing pieces. The utility model utilizes a chimney to discharge soot heat. A minitype blower drives into cold air from the top to form compulsive converse-flow heat exchanging, and the hot-air is discharged from a hot-air mouth at the bottom with the highest temperature 280 DEG C. And the hot-air mouth is provided with a water-pouring box to control the indoor temperature.

Description

Hot-air cylinder

The utility model belongs to heating technology, is the part of domestic briquet stove and a kind of device of application thereof, the equipment of particularly suitable heating of house in winter.

Present domestic briquet stove generally is made up of stove body and chimney.Hold concurrently for heating in the winter time, but this heating mode is unfavorable for to each room heat supply owing to adopt the freely-movable heat exchange, and the thermal efficiency is very low, and most of heat is fallen by flue gas loss, and a kind of known native heating installation is arranged at present, it adopts intermediate medium water, Natural Circulation in radiator and pipeline, the heat of absorption stove body and chimney, by radiator to air freely-movable heat exchange, but it makes in the room temperature rise too slow because water temperature is low, and circulation rate is slow, and the cost height takies floor space; Another utility model hot blast domestic heating stove (application number 85203991) adopts double-layer furnace body and double-deck chimney, utilize the natural circulation heating air to guide the heating of top, room into, but its circulation rate is slow, and Btu utilization is less, and the price height; Also have a kind of utility model warm-air type to use kitchen range (application number 87201345), it only makes bilayer with the stove body, force the following current heat exchange to guide top, room into blower fan, and flue gas loss is not utilized, and cost is also higher more.

Task of the present utility model is in order to overcome above-mentioned shortcoming, to utilize on the basis of original coal stove, design one simple in structure, cost is lower, heating is rapid, and renewable room air, regulates the thermal chimney of indoor air humidity.

Feature of the present utility model is: change the single thin layer iron sheet chimney of general domestic briquet stove into bilayer, its inner core is still the chimney that is used to discharge fume, overlap the urceolus of a sheet iron system outside again, make and form a space interlayer between chimney and urceolus, the spirality fin that is fixed on the stack extension outer surface is arranged in this interlayer, seal between outer top and internal layer chimney, air from mini fan (or indoor) from top (or bottom) squeeze into the space interlayer, carry out counter-flow heat exchange along spirality fin rotation decline (or rising), hot blast is discharged by bottom (or upper end) and is delivered to each room, increase the disturbance quantity of air, the heat transfer rate accelerates.And on hot-blast outlet pipe, adorn a trickle box, to regulate air humidity.The warm-air pipe that is upturned is arranged at the top of urceolus.

Below contrast accompanying drawing again, be described further in conjunction with the embodiments.

Shown in the accompanying drawing integral body of thermal chimney, the normal domestic use coal stove is directly installed on the A place of elbow (5), do not change the original purposes of coal stove, the hot flue gas that utilizes coal stove to produce enters flue (or atmosphere) through stack extension (1) by the B place, simultaneously, by outdoor gentle breeze machine (9) fresh air is squeezed into the interlayer that is made of special urceolus (3) and stack extension (1) through cool air hose (10), descend along spirality fin (4) rotation that is fixed on the stack extension (1), cold air and stack extension (1) and fin (4) force the reverse flow surface heat exchanging, cold air is heated gradually, finally the C from elbow (6) discharges hot blast, be sent to the bottom in each room again through pipeline, this makes 38% of flue gas loss obtain utilization, the hot blast temperature of discharging is up to 280 ℃, suppose not outwards heat radiation (under the adiabatic condition) of room, when hot air flow is 1m ³/ minute, by 200 ℃ of calculating of general hot blast temperature, per hour discharge the heat of 1224 kilocalories, can be with 40m ²Room (high 3 meters) be heated to 50.12 ℃ by 10 ℃ because hot blast enters from the bottom in room, room, strengthened the air agitation in room, indoor temperature is evenly risen.When room air was dry, the water in the water box (7) splashed in the hot blast through adjusting screw(rod) (8) and to vaporize, and has increased the humidity of hot-air, to reach the purpose of regulating indoor humidity.When having a power failure or not driving the gentle breeze machine, open detachable cap (2) at this moment cold air enter interlayer from elbow (6) C, rise along the spirality fin, carry out the freely-movable heat exchange, the detachable cap (2) of the warm-air pipe (11) that hot-air is upturned from urceolus (3) top through opening discharged, and can install pipeline additional, guides each room into, reach the purpose of heating, but this mode is not as the former thermal efficiency height.

The utility model is rational in infrastructure, installs simple and easyly, easy to use, does not take the interior space, the heat transfer rate is fast, and thermal efficiency height can be regulated indoor humidity, is that general heating equipment can not be compared, price is low, can save a large amount of metal materials, is another characteristics of the present utility model.
