Abstract

PURPOSE:To improve comfortability and ensure safety of a floor-heating device utilizing an exhaust heat from a chimney type stove installed to the interior of a chamber, according to a method wherein a chimney is formed with an inner pipe, through combustion exhaust gas flows, and an outer pipe, through which an indoor air passes, the upper part of the outer pipe is released at the upper part of the interior of the chamber, and the lower part thereof is connected to a suction part. CONSTITUTION:A channel 2 forms a double pipe of an inner pipe 7 and an outer pipe 8, and the inner pipe 7 is connected to a stove 7, the outer pipe 8 being released at the upper part of the interior of a chamber. When the stove 1 is burnt and a blower 9 is actuated, the air in the upper part in the chamber is sucked through the upper part of the outer pipe 8, and the air is heat-exchanged with high-temperature combustion exhaust gas flowing through the inner pipe 7. The indoor air increased in temperature is fed through the lower part of the outer pipe 8 to a radiation panel 6 with the aid of the blower 9 for floor heating. The air in the upper part of the interior of the chamber is sucked, and the air is heat-exchanged with high-temperature combustion exhaust gas. The air increased in temperature is fed to the radiation panel 6 located to the lower part of the interior of the chamber, and this produces an effect that indoor temperature distribution is uniformized. Further, since, even if the blower 9, being a heat conveying means, is failed in operation, a thermal medium is the air, there is no risk of boiling occurring in the chimney 2 being a heat exchanger part.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a floor heating system that utilizes the exhaust heat of a so-called pot-type kerosene stove, which exhausts combustion exhaust gas outdoors through a chimney, as radiant heat from the floor surface. It is.

BACKGROUND OF THE INVENTION As shown in FIG. 2, a conventional floor heating system of this type includes a heat exchanger 3 installed in a chimney 2 that discharges combustion exhaust gas from a stove 1 to the outside, an open expansion tank 4, and a circulation system. pump 5
and a heat radiation panel 6 constitute a circulation circuit, the liquid medium is circulated by the operation of the circulation pump 5, and the temperature of the liquid medium is raised in the heat exchanger 3 by the combustion exhaust gas from the stove 1,
Radiant heat from the heat radiation panel 6 was used to provide floor heating.

Problems to be Solved by the Invention However, with the above configuration, the uniformity of indoor temperature distribution, which is a feature of floor heating, cannot be said to be sufficient because of the discharge and radiation from the stove 1. Also,
There is also a problem in that the liquid medium boils inside the heat exchanger a when the circulation pump 5 fails.

The present invention solves such conventional problems, and aims to improve comfort and ensure safety of a floor heating system that utilizes exhaust heat from a chimney-type stove installed indoors.

Means for Solving the Problems In order to solve the above problems, the floor heating system of the present invention has an inner pipe through which combustion exhaust gas passes through a stope chimney that exhausts combustion exhaust gas outdoors through a chimney, and an inner pipe through which indoor air passes. The upper part of the outer pipe is open at the upper part of the room, the lower part is connected to the suction part of the blower, and the discharge part of the blower is connected to the heat dissipation panel for floor heating. .

According to the above-described structure, the present invention sucks air from the upper part of the room through the outer tube by operating the blower, exchanges heat with high-temperature combustion exhaust gas passing through the inner pipe, and passes the heated indoor air through the blower from the lower part of the outer tube. Sent to the heat dissipation panel.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

In FIG. 1, a stove 1 is provided with a chimney 2 for exhausting combustion exhaust gas from the stove 1 to the outside, and a heat radiation panel 6 is installed on the indoor floor. The chimney 2 is a double pipe consisting of an inner pipe 7 and an outer pipe 8. The inner pipe 7 is connected to the stove 1, and the outer pipe 6 is open at the upper part of the room, and the lower part is used for the suction of the blower 9. The discharge part of the blower 9 is connected to the heat radiation panel 6.

In the above configuration, when the stove 1 burns and the blower 9 operates, air from the upper part of the room is sucked in through the upper part of the outer pipe 8, exchanges heat with the high temperature combustion exhaust gas passing through the inner pipe 7, and heats up the indoor air. is sent from the lower part of the outer tube 8 through the blower 9 to the heat radiation panel 6, and floor heating is performed. Stove 1
is inside the room, and due to convection, the temperature distribution inside the room is usually high at the top and low at the bottom, but with the configuration of the present invention, air from the top of the room is sucked in and exchanged heat with high-temperature combustion exhaust gas to raise the temperature. Since the air is sent to the heat radiation panel 6 at the lower part of the room, there is an effect that the indoor temperature distribution becomes uniform. Furthermore, even if the blower 9, which is the heat transfer means, breaks down, there is no risk of boiling in the chimney 2, which is the heat exchanger section, because the heat medium is air.

Effects of the Invention As described above, the floor heating apparatus of the present invention provides the following effects.

(1) The chimney is a double pipe consisting of an inner pipe and an outer pipe, and the air from the upper part of the room is sucked in from the top of the outer pipe, and the air from the upper part of the room is exchanged with the high temperature combustion exhaust gas passing through the inner pipe, and the heated indoor air is transferred to the outer pipe. Since the heat is sent from the bottom through the blower to the heat dissipation panel at the bottom of the room, the uniformity of the indoor temperature distribution, which is a feature of underfloor heating, is maintained and comfort is improved.

(2) The heat medium that exchanges heat in the chimney is air, so it is safe because there is no risk of boiling even in abnormal situations such as a blower failure.
