Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a cooling/heating air supply device for heating and cooling a desired small indoor space using air under the floor.

The device of the present invention economically and efficiently cools and heats indoor rooms using the air accumulated in the underfloor spaces of buildings with underfloor spaces. Heating involves supplying and combusting air under the floor. By using the air in the underfloor space, the air under the floor of the building can be exhausted, so it has the effect of removing moisture from the underfloor air, and can be used as an air control for general houses and buildings with large underfloor spaces. be.

BACKGROUND ART Conventional air-conditioning and heating devices use indoor air to heat the entire room, such as oil stoves, and are designed to heat and cool each room individually.

This is uneconomical from the point of view of energy conservation, and actually results in excessive cooling and excessive heating.

Purpose of the invention The present invention provides a device that performs heating and cooling using the air under the floor.Summer cooling is performed by sucking the air under the floor with a temperature difference of 5 to 10 degrees Celsius into the room.
Winter heating is performed by supplying underfloor air as combustion oxygen and sucking and releasing hot air into a predetermined space.

The first purpose of the cooling/heating air supply device using underfloor air according to the present invention is to save energy such as fuel savings and improve economic efficiency.

In other words, a heater installed in one place supplies warm air to several places, or cold air under the floor is used to supply cold air to several places, and the cooled and warm air is discharged into a relatively small space, eliminating waste. The purpose is to achieve cooling and heating effects.

The second purpose is to provide heating and cooling without polluting the indoor air.

The purpose is to take combustion air from under the floor outdoors, release hot and cold air into a relatively small space for heating and cooling, and discharge it to the outside as necessary to perform heating and cooling without consuming indoor air.

The third purpose is to collect air under the floor while preventing odors, and to guide air from relatively humid directions of the underfloor air, such as the center of the house or the kitchen, to collect the air under the floor. The idea is to agitate the air and increase the moisture-proofing effect under the floor.

Structure of the invention The cooling/heating air supply device using under-floor air according to the present invention connects an intake pipe that penetrates the floor and is installed vertically under the floor and a suction blower installed indoors to transfer and utilize the under-floor air indoors. It is.

The suction pipe and the suction blower are connected directly through a pipe or with an air conditioner such as a kerosene stove or cooler, and utilize the underfloor air for combustion, cooling, etc.

The suction pipe is installed vertically through the floor so as to be connected directly below the combustion part of a kerosene stove, etc. The suction pipe is equipped with activated carbon to prevent odors, and has an inlet opening in a predetermined direction. It is configured to be oriented in the direction of underfloor air flow.

Embodiment The embodiment shown in FIG.
A heater 2 such as a kerosene stove is connected to the suction pipe 1 installed vertically in the air, and air is supplied to the combustion section 3 for combustion, and the heated air is passed through a suction port 4 opened at the top of the back of the heater 2 through a pipe. 5 with a suction blower 6, discharges the air into a relatively small space 7 to perform partial heating, and exhausts the air to the outside with an exhaust pipe 8 as required.

Figure 2 shows an example of its construction.
This figure shows a configuration in which warm air is transferred from a vertically installed heater 2 to a small space 7 in each room through pipes 5, 5 using respective suction blowers 6.

The suction cylinder 1 is vertically installed through a through hole drilled in the floor F, and has a structure in which activated carbon 15 is inserted between an outer cylinder 12 having a small hole 11 and an inner cylinder 14 having a small hole 13, or in a fixed direction. An outer cylinder 12 with an opening 16 formed therein and a mesh 1
A configuration is devised in which the inner cylinder 14 is equipped with 7 and 18. The air under the floor has a temperature difference of 5 to 10 degrees Celsius from room temperature in both summer and winter, and that air is heated using activated carbon.
It removes the smell and uses it.

Providing flow to the air under the floor is also important for building management purposes such as preventing rot and exterminating pests. In particular, it is preferable to form an opening 16 opening in a certain direction in the outer cylinder 12 so as to form a flow of air by sucking the air toward a lower part of a water area such as a kitchen.

The heater 2 has a unique structure due to the configuration of the present invention.

As shown in FIGS. 1 and 3, the heater 2 has an air intake port 20 opened below the center of the combustion section 3, and is connected to the intake pipe 1 vertically installed under the floor and fixed with screws etc. will be installed.

An annular recess 21 is provided around the combustion section 3, and a horizontal scale 22 is provided on the inner surface of the recess 21.

The annular recess 21 is used as a level when installing the heater 2 by filling water 23 therein.

The annular recess 21 may normally be left empty, but it can also be filled with water 23 for safety and to provide steam.

24 in the figure is a packing, which connects the intake pipe 1 and the air intake port 20 without play.

The front surface of the heater 2 is closed with a reflecting plate 26 attached as shown by an arrow 25 so as to be openable and closable. A small window 27 for checking for fire may be provided in the front part.

The reflective plate 26 forms a reflective surface on its inner surface to reflect heat as indicated by an arrow 28, and the hot air from the combustion section 3 is directed toward the suction port 4 provided on the back surface of the heater 2. .

In other words, the heater 2 is configured to mainly send hot air to the suction port 4 rather than heating its surroundings or the room in which it is installed.

Of course, if the reflector plate 26 is opened, it can be used as a normal heater.

A pipe 5 made of synthetic resin, such as a square vinyl pipe, is connected to the suction port 4.

A suction blower 6 is connected to the pipe 5, and when the suction blower 6 operates, hot air from the heater 2 is sucked through the suction port 4.

A pipe 5 is further connected to the suction blower 6, and hot air is discharged into the small space 7.

The small space 7 is formed of a kotatsu type or a heat insulating material.

A discharge pipe 8 to the outside is provided in the small space 7 as required.

By providing the discharge pipe 8, the hot air can be smoothly transferred.

The pipe 5 connecting the heater 2 and the small space 7 is preferably a rectangular pipe and is laid on a tatami mat.
It is fixed in several places.

The stopper 30 can be inserted into the tatami mat and fixed with a pin, and can be easily removed for disassembly and assembly.

What is shown in Fig. 4 is for using underfloor air as cold air, and shows a pipe 5 connected directly to the intake pipe 1 or a cooler 40 shown by a dashed line, and a suction blower. 6 for transferring cold air to each small space 7.

When the suction blower 6 is operated and the heater 2 is combusted, the underfloor air is sent in the order of arrows A, B, C, D, and E, supplying cool and warm air to the small space 7.

The suction blower 6 is capable of adjusting the temperature of hot air by taking in outside air.

Effects of the Invention The present invention is capable of heating and cooling air generated by one air conditioner/heater by enclosing it into a small space without wasting it, and has the following effects.

Thermal energy generated by air conditioners and heaters can be used without waste.

For example, in a home, if each room has a small kotatsu-shaped space, efficient and sufficient heating can be achieved.

Since the air under the floor is used while creating a flow, it is preferable for preservative management under the floor where humidity is high.

It is clean because it provides combustion heating without consuming indoor air.

Heaters and the like are highly safe because their combustion parts are not directly exposed.

Since the intake cylinder is connected directly below the heating part of the heater, air supply is smooth, and since it is equipped with activated carbon, there is no odor.
