BACKGROUND OF THE INVENTION
The present invention relates to a floor heating unit with an air layer, which is provided in a house or the like.
[0002]
[Prior art]
Various conventional wooden floor hot water type floor heating units have been proposed. For example, as disclosed in Japanese Patent Publication No. 7-18558, a U-shaped groove is formed in a panel base, and the U-shaped groove is cut at an end of the panel base. It is intended to make sure that the hot water pipe is easily provided by providing a notch. However, these have caused problems such as wooden floor noise, floor floating, squeaking noise, warpage, and deformation. Further, as disclosed in Japanese Patent Laid-Open No. 11-6629, in the underfloor space, a heat insulating material is laid on the soil, a meandering heat exchange pipe is placed on the upper surface of the heat insulating material, and further covered with livestock concrete. It is a heating system that blows air in the underfloor space with an air supply fan and sends warm air to each room with a warm air grill. In this system, the heat exchange pipe is covered with livestock concrete and the heat exchange efficiency is poor. Fans are required to heat up each room, the heat source is large, the fan cost and fuel costs are bulky, and maintenance costs are also difficult, and this is a heat exchange pipe (hot water pipe) from the boiler The concrete and air under the floor are heated and exhausted by wall pipes and warm air grills in each place to sequentially heat and exhaust the first and second floor rooms. Keep at room temperature Requires a uniform air flow, so it is limited to such buildings, and even a highly airtight and highly insulated structure can not cope with everything, and it is necessary to forcibly send air with an air supply fan In addition, since there is no correspondence to the cold draft under the window, there is a difference in room temperature depending on the presence / absence of the window in each room, and furthermore, the individual rooms cannot be sound-insulated, and the generated odor is transmitted to all rooms. Furthermore, there are some which use an air conditioner installed indoors as in Japanese Patent Application Laid-Open No. 10-54576 and Japanese Patent Application Laid-Open No. 9-310872, but this has an extra load on the air conditioner. It is necessary, and the warmth of the floor is slow, and as described in Japanese Patent Laid-Open No. 10-54576, the flow of temperature-controlled air from the air conditioner and partial floor heating are used. Further, in JP-A-7-229629, a floor is composed of a surface plate and a heat insulating plate opposed to the lower surface of the surface plate through a plurality of horizontal rails parallel to each other. The space surrounded by the two horizontal rails is used as a hot air passage, and a groove made of heat insulating material is provided on both sides of the heat insulating plate over the entire length of the room, and supplied from one end of one groove. The hot air is passed through each hot air passage and is discharged from the other end of the other groove. In this case, the floor heating of the room is uneven or it is necessary to supply hot air with a large capacity. This also generates warm air outside the floor, forcibly sends it to the floor with a fan, exhausts it from the opposite wall, and returns the air to the source of warm air. As above, it requires a forced circulation fan (power), and the return air in each room Mixed. Further, as disclosed in JP-A-63-273737, the underfloor space is enclosed by a partition plate, hot air is blown through a pipe, and the underfloor space and the above floor interior are communicated with a wall surface such as a window to eliminate unnecessary heating. In order to prevent dew condensation, the windows and their surroundings are doubled as in JP-A-5-141708, and air-conditioned air is supplied to block the influence of outside air, or JP-A-60-138337. As described in the publication, a heater is arranged near the lower end of the window, and the curtain is arranged such that the lower end of the curtain is located on the indoor side of the warm air outlet of the heater, and the blowout from the hot air outlet Although the room is heated by warm air, a forced circulation fan (power) is required or a heater is installed near the window, which has the above-mentioned various drawbacks. , Part of the room A bunch, it is necessary to the windows and peripheral to double, also increases the complexity and cost structure.
[0003]
The present inventor previously disclosed Japanese Patent Application Laid-Open No. 3-291426 as a wood-based panel unit for heating, and Japanese Patent Application Laid-Open No. 6-74472 for solving inconveniences such as wooden floor noise, floor floating, squeaking noise, warping, and deformation. And a registered utility model No. 3000557. In this structure, each air layer is formed between a wooden floor, a heat insulating plate, and a warm floor joist, and a hot water pipe disposed in the air layer is wrapped with a heat radiating plate such as an aluminum thin plate to heat and heat radiating portions. The present invention is to more actively utilize such an air layer. And it is said that it is ideal to install the heating equipment generally provided in a house etc. in a lower part of a window, whether it is a fan coil unit or a panel heater. The reason for this is to install a heating device in the lower part of the window in order to warm the air due to the cold draft from the glass window (the generation phenomenon of indoor air cooled by the cold glass window) to make a comfortable heating space. It has been found that it is possible to measure the rise in room temperature more quickly by paying attention to this. In the present invention, the convection speed can be varied by reversely utilizing the cold draft phenomenon and the temperature difference between the air under the window and the floor heating air layer. That is, when the room temperature is about 20 degrees C., the air layer temperature is 30 to 35 degrees C. Therefore, the lower the outside air temperature, the lower the air temperature under the window. Ascending will slow down the convection velocity. This structure allows the convection speed to be increased or decreased depending on the air temperature under the window without using a forced fan (power) as found in the prior art. Also, if the air under the window is warmed in reverse by sunlight and the air layer temperature reaches 30-35 ° C, the convection will stop, and if the air under the window rises further, it will become a reverse convection action and during cold draft The air inlet of the air turns into an air outlet and changes to work to quickly warm the cold room where the sun does not enter. In this way, it is possible to create a faster and more comfortable indoor heating environment by changing the convection speed, stopping it, or making it reverse flow according to the state of the air temperature under the window, and this creation (air convection) It has been found that it can provide a floor heating unit with a more energy-saving structure because it uses no power.

Air heated in the air layer The rising air tends to rise under the window 11, and the raised air is sucked in from the suction air inlet 10 of the opposing part not affected by the cold draft, and more active convection is generated. As shown in FIG. The convection action is performed. As described above, the floor heating according to the present invention can positively heat the cold air generated by the cold draft under the window in addition to the radiant heating from the original wooden floor. The warming convection action accelerates the indoor temperature rise at the start of heating, which is also an energy saving measure. In addition, the convection speed can be accelerated or slowed by the air temperature under the window, and if the air under the window is warmed to the air layer temperature by sunlight, the convection stops or the air under the window If it rises further, it will become a reverse convection action, and the suction air port at the time of a cold draft will turn into a discharge air port, and it will change so that it may work to warm up the cold room part where a sun does not enter quickly. In this way, it is possible to create a faster and more comfortable indoor heating environment by changing the convection speed, stopping it, or making it reverse flow according to the state of the air temperature under the window, and this creation (air convection) Can be used without power. Furthermore, by attaching fragrances, deodorants, etc. near the inside and outside of each air vent, you can take a natural bath with the circulated air during room heating, clean it, remove the smell, A fragrance can be created to create a more comfortable living environment.
