JP2002039628A - Heat-absorbing flue of firewood, gas, oil burning space heater - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a heat-absorbing flue of firewood, gas, or oil-burning space heater for increasing heating efficiency, contributing generally to conservation of resources and abatement of air pollution caused by flue-gas emission, in view of the fact that those heating appliances used in cold districts are operated in combination with other kinds of heating appliances, because of low efficiencies of the fuels considering the consumption. SOLUTION: The flue (1) is provided with an internal flue (3), a small ventilator (3) attached to the flue side, and a hot-gas exhaust port (5) made on the side opposite to the ventilator.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an endothermic chimney in which a chimney of an existing stove, gas or oil stove is provided with an interior chimney and a blower.

[0002]

2. Description of the Related Art A conventional chimney has a structure in which most of the fuel combustion heat is released to the outside together with the combustion exhaust gas, has a low thermal efficiency, consumes a large amount of fuel, increases the heating cost, and wastes resources in a large sense. Further, in recent years, there has been a concern that one of the causes of air pollution may be caused by a large amount of combustion exhaust gas being discharged to the outdoors.

[0003]

In the conventional chimney, about half of the fuel combustion heat was emitted to the outside. However, by installing and using this device, the chimney was fanned at the place where the chimney passed through the room. Depending on the utilization angle, it is possible to absorb the residual heat of the room and agitate the warm air that is high in the room (the ceiling part), while further improving the uniform heating temperature of the entire room and saving fuel. Ultimately, resources can be saved, and by reducing combustion exhaust gas, air pollution can be suppressed.

[0004]

Means for solving the problems An interior chimney (3) and an interior cylinder are formed by cutting a central portion of the chimney (1) to a size suitable for the small ventilation fan (2) and fixing the small ventilation fan (2) to the chimney (1). After assembling the fixing plates (6) and (7), the stove combustion heat is discharged to the outside together with the combustion exhaust gas with a device that is inserted into the chimney (1) so as to be inserted and fixedly mounted (this may be baked fixed mounting). It removes the heat from the chimney at the previous location and increases the heating effect.

[0005]

Embodiments of the present invention will be described below. (B) Cut and open the center of the chimney (1). (4) Attach a small ventilation fan (2). (B) Two interior chimneys are fixed inside the chimney (6) (7)
Attach and fix. (C) Cut the hot air outlet (5) into the chimney on the opposite side of the small ventilation fan. (D) The power of the small ventilation fan is electric. When the present invention is used with the above structure, it can be used during normal operation of the fuel stove ignition operation. In addition, a sirocco fan (used for a wall-mounted cooler, etc.) may be used instead of a small ventilation fan. To improve thermal efficiency, the interior chimney is an endothermic chimney with firewood, gas and oil stoves.

[0006]

[Examples] In the actual use of the invention, the fuel consumption was less than half that of the existing chimney.

[0007]

According to the invention, the indoor air can be agitated by fanning out the hot air from the chimney, so that the entire room can be uniformly heated, and the fuel consumption can be further reduced. It also reduces combustion gas emissions and reduces and prevents environmental air pollution.

Claims (1)

[Claims] 1. A small ventilation fan is installed in the center of the chimney (1). The small ventilation fan is cut open to fit to fit the small ventilation fan, and the interior chimney (3) is mounted inside the chimney (1). An endothermic chimney that uses a small ventilation fan (2) to remove the heat from the chimney at a location where most of the heat from the stove is vented outdoors, with a ventilation outlet (5) provided opposite the location.
