Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to an air supply device for supplying warm air to each room of a house, and particularly to a technique for purifying intake air.

[0002]

[Prior art]

 With the increase in airtight houses, the demand for indoor ventilation is increasing recently. Conventionally, for ventilation of indoor air, ventilation holes are provided in the outer wall to penetrate inside and outside, and a hood (ventilator) is provided at the outdoor opening of the ventilation hole to prevent rainwater from entering, while the ventilation port is on the indoor side. Often has a structure provided with a ventilation device (register) for opening and closing.

However, in a cold region such as Hokkaido, the outside air temperature is extremely low in the winter, so that such a structure has a problem that heating efficiency is lowered.

Therefore, a ventilation unit that warms the introduced outside air and sends it to each room is desired. It is desirable to install such a ventilation unit under the floor of the building in consideration of the efficiency of heating the outside air. FIG. 3 shows an example of the structure of a ventilation device based on such a method.

In the figure, reference numeral 1 is a ventilation unit incorporating a heater device (not shown), 2 is an air supply duct, 3 is an underfloor space, 4 is a hood attached to an outer wall, and R is an indoor space. Reference numerals S1 and S2 are humidity sensors mounted on the wall surface in the room, S3 is a noisy gas sensor, S4 is a human sensor, and G is an intake grill. A fan motor for ventilation is provided in each of the sensors S1 to S4, and the indoor air is forcibly exhausted if necessary due to air pollution. Therefore, the ventilation unit 1 need not be provided with a fan motor.

The air in the underfloor space 3 is relatively warm in the winter and cool in the summer. Therefore, it is possible to use the heater of the ventilation unit 1 to warm the outside air in the winter and to send the cool outside air to the room R in the summer. As the heater device used in such a ventilation unit 1, various means such as a hot water circulation system and an electric heating system can be used.

[0007]

[Problems to be solved by the invention]

 Such a ventilator is satisfactory in terms of adjusting the temperature of the introduced outside air. However, since the underfloor is difficult to clean and is a shaded area, molds and germs are liable to be generated, and there is a problem that these are sucked from the ventilation system and sent into the room.

[0008] In order to solve such a problem, it is possible to provide a filter means at the air inlet or the air supply opening of the ventilation device to remove dust and germs, but the ventilation unit 1 is installed in the underfloor 3. The filter is not easy to replace because it is installed. It is also possible to install a filter on the route of the air supply duct, but there are practical problems such as imposing excessive maintenance costs on the user.

Further, since the outside air has a high humidity in the summer and is dry in the winter, it is difficult to adjust the humidity in the room only by the ventilation unit.

Therefore, an object of the present invention is to purify intake air and to adjust humidity without providing a filter in a ventilation unit or an air supply duct system.

[0011]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the ventilator according to the present invention has an air supply device equipped with an air heating means inside, installed under the floor, and is provided in each room via an air supply pipe connected to the air supply device. It is a device for sending in air, and a charcoal mat in which a charcoal piece and / or charcoal powder is enclosed in a bag body made of a breathable sheet is arranged at an appropriate position under the floor.

[0012]

[Function] Since charcoal has a large number of fine voids, it has a so-called humidity control property of absorbing moisture when the humidity is high and discharging the moisture when the outside air is dry. In addition, it has recently become known that charcoal has a far-infrared emitting property that has antibacterial effects, antiseptic effects, and antirust effects.

Therefore, an appropriate size of charcoal pieces or charcoal powder is covered with a breathable sheet and placed under the floor. As a result, the humidity of the air around the ventilation unit is adjusted to a desirable state, and it is possible to keep the underfloor air clean at all times by the action of antibacterial, antiseptic and rust prevention.

Charcoal does not deteriorate in action and effect even if left for a long time. Therefore, the charcoal mat placed under the floor may be left as it is without any maintenance.

[0015]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an example of a ventilation device according to the present invention. The ventilation device according to the present invention includes a ventilation unit 1 having a built-in heater device, an air supply duct 2, an outer wall hood 4, and the like, as in the case shown in FIG. A plurality of charcoal mats 10 are provided under the floor 7. Reference numeral 8 is the foundation concrete of the house, and 9 is the foundation opening.

As shown in FIG. 2, the charcoal mat 10 is a bag 11 made of a breathable sheet material, for example, a linen cloth or a paper bag, into which charcoal pieces 14 or charcoal powder 15 are loaded. Please keep closed. In terms of the dehumidifying action and antibacterial action of the charcoal, it is not necessary to seal it in the bag 11. However, if the charcoal pieces 14 and the charcoal powder 15 are directly sprayed under the floor, the ventilation unit 1 inhales the dust of the charcoal as it is, so the charcoal is enclosed in the bag 11 and placed under the floor.

The charcoal mat 10 may be left under the floor as it is and need not be moved. Therefore, the bag 11 may have a simple one pocket structure, and need not be divided into a plurality of pockets by quilting or the like. Needless to say, the structure of the bag 11 may be appropriately selected because the function and effect of charcoal will not be reduced even if it is divided into a plurality of pockets. The charcoal according to the present invention is not particularly limited in size of charcoal pieces or charcoal powder.

Since the partition of the basic concrete 8 is different for each house, the size of the charcoal mat 10 can be freely set. Also in FIG. 1, a small charcoal mat 10 (S) is arranged in the underfloor 7 (S) having a small partition, and a large charcoal mat 10 (L) is arranged in the large underfloor space 7 (L). Of course, it is also possible to use the charcoal mat 10 in the same size. For example, the size of one piece is set to about 45 × 45 × 6 cm in length / width / width, and this is made the size of a small charcoal mat 10 (S), while four pieces of this are laid to make a large charcoal mat 10 (L) and so on.

The charcoal mat 10 is not limited to the underfloor portion where the ventilation unit 1 is installed, but is preferably placed under the entire floor. In FIG. 1, the charcoal mat 10 should be arranged not only in the central floor 7 (M) where the ventilation unit 1 is arranged but also in the floors 7 (S) (L) on both sides. This is to dehumidify, humidify, and purify the air under the floor.

For this purpose, it is desirable that the charcoal mat 10 is laid under the entire floor without any space. However, if only the function of the charcoal mat 10 is taken into consideration, it is sufficient to lay it appropriately at least in the vicinity of the foundation opening 9 through which the outside air flows and in the center under the floor. Further, when laying, it is efficient to arrange the charcoal mats 10 so as to draw a triangle.

Therefore, according to such a configuration, the underfloor air is absorbed by the charcoal mat 10 when the humidity is high to reduce the humidity, and when the outside air is dried, the humidity is discharged and retained, so that the air is sent indoors. The air humidity to be taken care of will always be adjusted to a favorable condition. In addition, the antibacterial, antiseptic, and deodorizing effects of charcoal prevent the growth of mold and other bacteria, so that the air sent can always be kept clean.

The ventilation unit 1 arranged under the floor sends the underfloor air into the room by the operation of the fan motors arranged in each room. It can supply warm and clean air with appropriate humidity, heated by any type of hot water. Since the purpose of the ventilator is to send clean air to the room and to discharge dirty air to the room, the charcoal mat 10 placed under the floor can further enhance the original purpose of the ventilator. Become.

The charcoal mat according to the present invention has the advantages of low cost, easy laying work, and no need for maintenance.

The charcoal mat according to the present invention may be mixed with wood pieces such as cypress in addition to charcoal. This is because cypress also has a humidity control property and a deodorizing effect. Also, as already explained, charcoal has its original function and effect semipermanently, so filter-like charcoal loading sheets may be placed in the intake opening, air supply opening and duct path of the ventilation unit body. Absent.

[0025]

[Effect of the invention]

 As described above, since the ventilation device according to the present invention has the charcoal mat placed under the floor, it can purify the intake air without installing a filter in the ventilation unit or the air supply duct system, and at the same time keep the air supply air clean. It can be maintained at an appropriate humidity.
