Description

  The present invention relates to a solar heating / drying system, and more particularly, in a system for indoor heating of a house with air heated by a solar heat collecting panel, the heated air is supplied to the floor under a route that does not penetrate the roof of the house. Solar heat collecting panel that can be used for heating, and at the same time, when the heated air is used for drying in the bathroom, it can be dried without causing pollen to adhere to the laundry suspended in the bathroom Is used for heating and drying (hereinafter sometimes referred to as a solar heating drying system).

Conventionally, a solar heat collection panel is installed on the roof or wall surface of a house body, outside air is supplied to the solar heat collection panel, and heated air (hereinafter sometimes referred to as heated air) is solar heat collection. A solar heating system (see, for example, Patent Documents 1 and 2) that is discharged from a panel, supplied to the floor under the house, and used for heating the interior of the house is used.
In addition, a solar heat collecting part is provided on the roof of the building, and a heat radiating part is provided on the foundation concrete part through a circulation path for returning the heat medium to and from the heat collecting part. An air circulation building provided with a hot water supply section through a circulation path for refluxing the heat medium, and provided with a switching valve for controlling the heat dissipation and the hot water supply by controlling the flow of the heat medium between the heat dissipation section and the hot water supply section In addition to thermal energy using midnight power), hot water warmed by using solar heat collected by a solar heat collector as a system heat source is stored in a heat storage tank in an electric boiler and directly It is used for heating and hot water supply in the interior of a house by a heat medium heated by solar heat collection, such as a heat storage type low temperature energy-saving heat energy system for high heat insulation and high airtight housing to be used (for example, see Patent Document 4). Solar system proposed To have.

  However, in a solar heating system using air as a heat medium, outside air is supplied directly into the solar heat collection panel, so when it is supplied under the floor of a house and used for heating in the house, it is scattered in the outside air. There was a serious drawback of taking the pollen in the room as it is. In other words, when pollen is scattered, if clothes or other laundry is sun-dried outdoors, the pollen will adhere to the clothes, so it is not possible to sun-dry clothes for people with pollen allergies outdoors. A dryer is used that dries laundry by heating or dehumidifying it. However, in recent years, there has been a demand for reducing the use of electrical energy as much as possible for heating the house and drying laundry because of the protection of the global environment. However, the number of people suffering from hay fever is increasing year by year, and the laundry is dried. Drying without touching the outside air with the machine is increasing.

Furthermore, when installing the solar heat collection panel on the roof of the house body, a duct for supplying heated air from the solar heat collection panel to the floor is installed through the roof. Therefore, it was necessary to give due consideration to measures against rain leaks on the roof. Furthermore, in a snowy area, such a solar heat collecting panel has a problem that it is difficult to acquire solar radiation due to snow.
On the other hand, when a solar heat collecting panel is installed on the wall of a house, there is a problem that the amount of solar radiation acquired is limited by the orientation of the wall and the distance to the adjacent house. Furthermore, there is also a problem that the installation of the solar heat collecting panel on the wall causes a problem in the appearance of the house.

  From the above situation, in the system that heats the interior of the house with the air heated by the solar heat collecting panel, the heated air is supplied to the floor under the roof without passing through the roof of the house body, and is used for heating. There is a need for a system capable of drying without using pollen on the laundry when the fresh air is used for drying in the bathroom.

The heated air exhausted from the solar heat collecting panel is used to heat the interior of the house by blowing air under the floor of the house. At the same time, at least a part of the air under the floor is blown into the bathroom to pass through the bathroom. When a system that blows air through a separate system, a drying system, or a path that supplies air directly under the floor of the house and a path that supplies air directly to the bathroom of the house, the system was heated by a solar heat collecting panel. When air is supplied under the floor without passing through the roof of the house body and used for heating, and at the same time, when the heated air is used for drying in the bathroom, pollen is applied to the laundry suspended in the bathroom. Adhere It can be dried by not found that the system is achieved utilizing a solar heat collector panel drying and heating, thus completing the present invention.

  That is, according to the first invention of the present invention, indoor air from which pollen has been removed by a filter is supplied from the lower part of a solar heat collecting panel installed on the roof of a building incidental to a house, while the solar heat collecting is provided. The heated air is discharged from the upper part of the heat panel, and then the heated air is blown under the floor of the house to heat the room, and at the same time, at least a part of the air under the floor is blown to the bathroom. Thus, there is provided a solar heating drying system (hereinafter sometimes referred to as “first system”) characterized in that the inside of the bathroom is dried.

  According to the second invention of the present invention, indoor air from which pollen has been removed by a filter is supplied from the lower part of a solar heat collecting panel installed on the roof of a building incidental to a house, while the solar heat collecting is provided. The heated air is discharged from the upper part of the heat panel, and then the heated air is individually blown through a path for supplying air directly to the floor of the house and a path for supplying air directly to the bathroom of the house. A solar heating / drying system (hereinafter, may be referred to as “second system”) is provided.

  According to the third invention of the present invention, in the first or second invention, when a temperature sensor is installed in the solar heat collecting panel and the temperature measured by the temperature sensor reaches a predetermined set temperature, A solar heating and drying system is provided that supplies air to a solar heat collection panel.

  The solar heating / drying system of the present invention is a system that heats indoors with air heated by a solar heat collecting panel, and heats the heated air under the floor without penetrating the roof of the housing body. At the same time, when the heated air is used for drying in the bathroom, the laundry suspended in the bathroom can be dried without adhering pollen. In addition, since the water vapor of the laundry is sent indoors, it is also effective in reducing indoor drying in winter.

Hereinafter, the solar heating drying system of the present invention will be described in detail.
The solar heating / drying system of the present invention is roughly classified into a first system and a second system, and both of them are provided with a solar heat collecting panel on a roof of a building incidental to a house, and the solar heat collecting panel. The indoor air from which pollen has been removed by a filter is supplied from the lower part of the solar heat collector, while the heated air is discharged from the upper part of the solar heat collecting panel, and the heated air is blown under the floor of the house to indoors. Is used for heating, and at the same time, it is used for the purpose of blowing air into the bathroom and drying the interior of the bathroom.
The main difference between the first system and the second system is that different methods are used for the flow path of the heated air. In the former, the heated air is blown under the floor of the house. However, while at least a part of the air under the floor is blown to the bathroom, in the latter, the heated air is directly supplied to the house floor and the house is directly supplied to the house bathroom. Thus, the air is blown through an individual route.

  In the first system, heated air is released into the underfloor space of the house and the room is heated as floor heating, or the heated air blower provided in the underfloor space is used to supply the heated air in the underfloor space in the house as well as in the bathroom. The air is controlled to a desired discharge amount in each room. That is, here, the blowing of heated air to the bathroom is performed by blowing a part or all of the air in the underfloor space to the bathroom.

  In the second system, for example, there is a method in which heated air is sent to the underfloor space of the house by piping and the discharge to the underfloor space and the amount of air blown to the piping to the bathroom are controlled by a distributor provided in the piping. Done. Thereby, the advantage that the ventilation conditions according to the degree of use in a bathroom can be secured is obtained.

  The building attached to the house used in the solar heating / drying system is not particularly limited, and is attached to the house for various purposes such as a terrace, a storeroom, a balcony having a separate roof from the housing body. The building is selected in consideration of the direction and the like so that good solar radiation can be obtained effectively.

  As a method for controlling the temperature of the solar heating / drying system, for example, when the temperature measured by the temperature sensor installed in the upper part of the solar heat collecting panel reaches the set temperature, the room air is supplied to the solar heat collecting panel. Is started. Here, 20-30 degreeC is used as preset temperature. As a result, the solar heating and drying system is efficiently used.

Hereinafter, examples of the present invention will be described in more detail with reference to the drawings. However, the present invention is not limited to these examples.
FIG. 1 is a schematic diagram showing an example of the first system of the present invention. Here, as the flow path of the heated air, at least a part of the air under the floor is blown to the bathroom while the heated air is blown under the floor of the house.
In FIG. 1, the embodiment of the first system includes a solar heat collecting panel 1 installed on a roof of a terrace attached to a house, a filter 2 that excludes pollen and house ducts from indoor air, and solar air collected from the indoor air. Panel blower 3 for supplying air to the heat panel, air supply port 9 for the duct for blowing indoor air to the solar heat collecting panel 1, and air outlet at the upper part of the solar heat collecting panel 1 for air heated by the solar heat collecting panel 1 A duct 5 that blows air from 10 to the underfloor 4, a bathroom blower 7 that blows air from the underfloor 4 to the bathroom 6, and a temperature sensor 8 that senses the temperature of the upper portion of the solar heat collecting panel 1.

  Here, the room air is supplied from the air inlet 9 in the lower part of the solar heat collecting panel 1 after removing pollen and house dust through the filter 2. After being heated by the solar heat collecting panel 1, it is discharged from the exhaust port 10 in the upper part of the solar heat collecting panel 1 and supplied to the underfloor 4 to the house to heat the underfloor 4. The underfloor 4 and the bathroom 6 are connected by a duct. The heated underfloor air without pollen is blown to the bathroom 6 by the bathroom blower 7 and the laundry suspended in the bathroom 6 is dried.

In FIG. 1, it is important to install a solar heat collecting panel on the roof of a building attached to a house. That is, by using the roof of a building incidental to the house as a place for installing the solar heat collection panel, the direction of the heat collection surface of the solar heat collection panel can be determined regardless of the direction of the house body. At this time, since the slope of the panel when installing the solar heat collection panel can be set freely, for example, even in a snowy area, it can be installed on the surface of the solar heat collection panel with a slope that is difficult to snow. Can increase the opportunity to get solar radiation. Thus, since the freedom degree of the setting of the azimuth | direction and gradient of a solar-heat collection panel is high, it can be made to acquire solar radiation more advantageously. For example, since the solar altitude is low in winter, increase the installation gradient of the solar heat collection panel, make the solar heat collection panel have a gradient that does not cover snow in snowy areas, or set the orientation of the roof of the incidental building Regardless of the azimuth, the orientation is determined so that the acquisition of solar radiation becomes large.
Furthermore, as the route of the heated air discharged from the solar heat collection panel, it can be blown under the floor of the house through the wall of the house, etc., thus preventing troubles such as rain leakage when passing through the roof of the house body Can do.

  The solar heat collection panel is not particularly limited, and a commercially available solar heat collection panel can be used. An example of this will be described using a conceptual diagram. 2, 3, and 4 respectively show a perspective view, a longitudinal sectional view, and a transverse sectional view from the back surface of the solar heat collecting panel. Here, an air supply port 9 and an exhaust port 10 are provided in the panel. In the panel, a metal corrugated plate 11 that absorbs solar heat rays is provided, and air flow paths 12 that recover heat by heat exchange are provided on both sides of the metal corrugated plate 11. Since the heated air rises along the gradient when the panel is installed, the panel is installed with an inclination so that the air supply port 9 is in the lower part and the exhaust port 10 is in the upper part.

Further, it is important to use room air as the air supplied to the solar heat collecting panel.
That is, indoor air is usually warmer than outside air, especially in winter, so when supplying indoor air to a solar heat collection panel, the heated air discharged from the solar heat collection panel rises to a higher temperature. Is done. For example, if indoor air that is about 5-10 ° C. higher than the outside air is blown to the solar heat collecting panel, air heated 5-10 ° C. higher than the case where the outside air is supplied can be obtained. Therefore, if this heated air is blown under the floor of the house and used for indoor heating, the underfloor can be heated more efficiently.

It is most important that the room air supplied to the solar heat collecting panel is blown after passing through a filter and excluding pollen and house dust floating in the air.
Thereby, clean air can be supplied to the floor and the bathroom. In particular, when this heated air is used for drying in the bathroom, it can be dried without causing pollen to adhere to the laundry suspended in the bathroom, so that the bathroom can be used as a drying room.

The filter used in the first system is not particularly limited, and any filter can be used as long as it can exclude pollen and house dust floating in the air. Various commercially available types and materials are used.
In the solar heating / drying system, since indoor air is circulated and used, there is an advantage that the content of pollen in the air can be suppressed unlike the outside air.

In FIG. 1, the temperature control of the first system of the present invention will be described.
When the house is heated (hereinafter referred to as the heating period), when the temperature sensor 8 in the upper part of the solar heat collecting panel 1 reaches a desired temperature or higher, the panel blower 3 is activated, and the room air is discharged. The solar heat collecting panel 1 is blown. The heated air heats the lower floor 4 of the house. At this time, when the laundry is dried in the bathroom 6, the underfloor air heated by manually operating the bathroom blower 7 can be supplied to the bathroom 6, and the laundry suspended in the bathroom 6 can be dried. .

  On the other hand, the laundry suspended in the bathroom 6 can be dried by manually operating the bathroom blower 7 at the time when the house is cooled (hereinafter referred to as the cooling period). During the cooling season, the temperature of the solar heat collecting panel 1 decreases due to radiative cooling. Therefore, when the temperature sensor 8 falls below a predetermined temperature, the panel blower 3 is activated, and the air whose temperature has decreased due to radiant cooling is discharged under the floor 4. It is possible to cool the house by cooling the bottom floor 4 by blowing air.

FIG. 5 is a schematic diagram showing an example of the second system of the present invention. Here, the flow path of the heated air is different from the first system shown in FIG.
As the flow path of the heated air in the second system, the heated air is blown through separate paths by a path for supplying air directly under the floor of the house and a path for supplying air directly to the bathroom of the house. Is.
In FIG. 5, the embodiment of the second system includes a solar heat collecting panel 1 installed on a roof of a terrace attached to a house, a filter 2 that excludes pollen and house ducts from indoor air, and solar air collected from the indoor air. Panel blower 3 for supplying air to the heat panel, air supply port 9 for the duct for blowing indoor air to the solar heat collecting panel 1, and air outlet at the upper part of the solar heat collecting panel 1 for air heated by the solar heat collecting panel 1 A duct 5 that blows air from the floor 10 to the underfloor 4 and the bathroom 6, a three-way switching shutter 13 installed in the duct, and a temperature sensor 8 that senses the temperature of the upper part of the solar heat collecting panel 1.

  Here, the duct 5 connected to the solar heat collecting panel 1 is connected to the bathroom 6 via the underfloor 4. Thereby, the heated air from the solar heat collecting panel 1 can be directly blown to the bathroom 6, and the laundry in the bathroom 6 can be dried. In this route, since the three-way switching shutter 13 is provided in the duct 5 in the underfloor 4, when the air is not blown into the bathroom 6, it is used for underfloor heating through a route for blowing heated air to the underfloor 4.

  As is clear from the above, the solar heating and drying system of the present invention is a system that heats the interior of a house with air heated by a solar heat collecting panel, and does not allow the heated air to penetrate the roof of the house body. While supplying air under the floor and using it for heating, when the heated air is used for drying in the bathroom, it can be dried without causing pollen to adhere to the laundry suspended in the bathroom. In a solar system used in the housing field, it is suitable as an energy saving technology having a pollen countermeasure.
