Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner that exhausts and circulates indoor air or cools and heats indoor air.

Traditionally, air conditioning equipment used to adjust indoor temperature.
There are ventilation systems that install electric fans on windows and walls to exhaust indoor air to the outside and suck in outdoor air into the room, and ventilation systems that are installed indoors to directly cool indoor air. Alternatively, an air conditioner/heater that heats the air is known. On the other hand, the increase in indoor temperature is caused by the fact that the air in the attic is heated through the roof, which receives sunlight during the day, and the heat of this heated air in the attic is further transferred to the indoor air through the ceiling. Therefore, in order to efficiently adjust the indoor temperature, for example, in order to prevent the indoor temperature from rising in the summer, it is necessary to eliminate the heated air in the attic. In order to raise the indoor air temperature in winter, it is preferable to actively take heated air from the attic into the room and circulate it.

However, as mentioned above, conventional ventilation systems can only provide ventilation between indoors and outdoors, and cannot process or utilize the heated air in the attic. Some devices directly cool or heat indoor air, and like the former, they cannot process or utilize heated air in the attic; The influence of air was not used to adjust the indoor temperature. In addition, in order to prevent the indoor temperature from rising due to the attic air in the summer and to use the attic air for indoor heating in the winter, ducts are installed inside the house by penetrating the ceiling and exterior walls to communicate between the attic, the outdoors, and the indoors. When installing a blower inside a duct, it is necessary to install a large-scale duct that penetrates the ceiling and exterior walls, which complicates equipment construction and increases equipment costs. Since the ducts are exposed and spoil the aesthetic appearance, it is necessary to conceal the ducts in order to fit them inside the house, which is difficult to implement.

This invention was made in view of the above-mentioned conventional circumstances, and includes forming a duct that communicates with the attic through an opening between the face plates of the upper part of the outer wall of the panel structure, and forming a duct that communicates with the attic through the face plate of the outer wall. A first ventilation hole, a second ventilation hole, and an exhaust hole communicating with the duct to the outdoors are formed, a blower is installed in the duct, and the opening and the first ventilation hole are selected at the top of the duct. a first damper that opens and closes automatically;
The above conventional problems are solved by providing a second damper in the lower part of the duct that selectively opens and closes the exhaust hole and the second ventilation hole, and providing a heat exchanger inside the duct. Yes, it prevents the indoor temperature from rising due to attic air in the summer, and achieves indoor heating using the attic air in the winter.In addition to being able to circulate indoor air and provide heating and cooling, it can be installed easily within the house and is easy to configure. The purpose is to provide an air conditioning system that is easy to implement.

Hereinafter, this invention will be explained in detail based on an embodiment shown in FIGS. 1 to 4.

In the figure, code 1 indicates a house, and this house 1
In this case, an indoor wall 10 and an outdoor space are partitioned by an outer wall W, and a ceiling 4 that abuts the upper part of the outer wall W on the indoor side partitions the indoor room 10 and an attic 5. The outer wall W is a panel-structured wall constructed by connecting a pair of parallel face plates M, M with a core material S, and the space between the face plates M, M of this outer wall W is utilized. The air conditioner 2 is constructed by using a duct 7 that communicates with the attic 5 near the eaves through an opening 6 at its upper end.
That is, the air conditioner 2 includes the duct 7 and a blower device 9 such as an electric fan disposed within the duct 7 by being supported by a support member 8.
The duct 7 is provided near the opening 6 of the duct 7 and above the air blower 9 (upper part in the figure).
and a first ventilation hole 11 communicating with the room 10;
A second ventilation hole 12 is provided below the air blower 9 in the duct 7 (lower in the figure) and communicates between the duct 7 and the room 10; The duct 7 is provided at a nearby position.
and an exhaust hole 14 communicating with the outside 13, and
Rotatably attached to the duct 7, the opening 6
and a first damper 15 that alternately closes either one of the first ventilation hole 11 and the second ventilation hole 12 and the exhaust hole 14, which are rotatably attached to the duct 7.
a second damper 16 that alternately closes one of the
Furthermore, within the duct 7, a second ventilation hole 1 is provided.
Heat exchanger 1 such as an air conditioner or heater placed near 2
It consists of 7. The support member 8 that supports the air blower 9 is attached by being fixed to the duct 7, and has a plurality of holes 18, 1 so as not to obstruct the flow of air within the duct 7.
8 is provided. Further, the first damper 1
5 and the second damper 16 are rotatable by being supported by shafts 19 and 20 fixed to the duct 7, and this rotation is performed by a rotary means such as a motor or a lever (see FIG. (not shown)
This can be done electrically or manually. (The rotation stop positions of the dampers 15 and 16 are shown in FIG. 1 by solid lines and two-dot chain lines). The reference numeral 21 indicates a ventilation hole, which is provided at an arbitrary position in the ceiling 4 and is located in the attic 5.
and the indoor room 10 are communicated with each other.

Next, the operation of this invention will be explained.

First, to explain the effect of raising the room temperature in the room 10 during the winter season, etc., as shown in FIG.
operating the rotation means to open the first ventilation hole 11 and close the first ventilation hole 11, and open the second damper 16 and the second ventilation hole 12;
Further, the rotating means is operated and rotated so as to close the exhaust hole 14. This establishes communication between the attic 5, the duct 7, and the indoor room 10, so if the blower device 9 is then driven, the air in the attic 5 will flow as indicated by the arrows B, C, D, and E in FIG. It is circulated along the route shown. On the other hand, the air in the attic 5 is heated through the roof 3, which is heated by sunlight during the day (indicated by arrow A in the figure).
The above-mentioned air circulation causes the air to be sent into the room 10 and raise the temperature of the room 10. At the same time, the second
If the heat exchanger 17 disposed near the ventilation hole 12 and within the above-mentioned air circulation path generates heat, the circulated air will be further heated and sent into the room 10.

Next, we will explain the effect of suppressing the temperature rise in the room 10 by discharging the heated air in the attic 5 outside the house 1 during the summer season, etc., as shown in the schematic diagram of FIG. , rotate the first damper 15 to close the first ventilation hole 11,
and closes the second ventilation hole 12 by opening the opening 6 of the duct 7 and rotating the second damper 16 to close the lower part of the duct 7;
In addition, the exhaust hole 14 is opened. As a result, the attic 5 and the outdoor area 13 are communicated via the duct 7, so if the blower device 9 is driven from this, the heated air in the attic 5 is discharged to the outdoor area 13 through the duct 7. (The air path at this time is shown by arrows F and G in FIG. 2). Next, to further explain the cooling operation in order to lower the temperature of the room 10, as shown in FIG. 3, the first damper 15 is rotated to close the opening 6 of the duct 7. At the same time, the first ventilation hole 11 is opened, and the second damper 16 is rotated to open the second ventilation hole 12 and the exhaust hole 1 is opened.
Close 4. With this, indoor 10 and duct 7
Since a circulation path for the air in the room 10 is formed by this, the blower device 9 is driven from this, and
When the heat exchanger 17 is operated to perform a cooling effect, the air in the room 10 is cooled while being circulated within the duct 7, and the room 10 is cooled. (The air path at this time is shown by arrows H and I in FIG. 3). This action for cooling is
It is also possible to carry out the operation explained in FIG. 2 in combination with the operation for discharging the heated air in the attic 5 to the outside. Moreover, the action for performing air conditioning can also be made into the action for heating the room 10 by switching the operation of the heat exchanger 17 to heating. This is effective when the temperature of the air in the attic 5 has decreased and the effect of utilizing the air in the attic 5 as shown in FIG. 1 is no longer necessary. Note that the air conditioner 2 configured as described above is configured to discharge air from the attic 5 to the outdoors through the inside of the outer wall W near the eaves of the roof. It is possible to ventilate the inside of the nearby exterior wall, increasing the ventilation inside the eaves and inside the exterior wall near the eaves, and has the effect of preventing rot in these parts.

Furthermore, the operation for discharging the air inside the room 10 to the outside 13 regardless of the season will be explained as follows.
As schematically shown in FIG. 4, the first damper 15 is rotated to close the opening 6 of the duct 7 and open the first ventilation hole 11, and the second damper 16 is rotated. The second ventilation hole 12 is closed by closing the lower part of the duct 7, and the exhaust hole 14 is opened. As a result, the indoor 10 and the outdoor 13 are communicated via the duct 7.
If the blower device 9 is driven from this point, the air inside the room 10 will be transferred to the outside 13 along the route shown by arrows J and K in the figure.
is discharged to.

In addition, in the case of the air conditioner 2 having the above configuration, since the internal space of the outer wall W is used for the duct 7, there is no need to perform special piping work for the installation of the duct 7. It is easy to install and fits well within the house 1. In addition, the face plates M, M of the outer wall W
By forming the ventilation holes 11, 12 and the exhaust hole 14, the duct 7 can be communicated with the attic 5, the room 10, and the outdoors, so construction such as piping is not necessary and construction is easy.

According to the device of the present invention configured as described above, the first damper closes the first ventilation hole and opens the duct opening, and the second damper closes the exhaust hole and opens the second ventilation hole. By operating the blower, warm air from the attic in winter can be sent into the room through the duct to heat the room. In addition, if the first damper closes the first ventilation hole and opens the opening, and the second damper opens the exhaust hole and operates the blower, warm air from the attic in summer can be exhausted outdoors. It is possible to suppress the rise in indoor temperature. By the way, since the air in the attic can be discharged outdoors through the inside of the outer wall near the eaves of the roof, it is possible to ventilate the inside of the eaves where moisture tends to accumulate and the inside of the outer wall near the eaves. This has the effect of increasing ventilation inside the exterior wall near the eaves and preventing rot in these areas. Furthermore, if the first damper closes the opening and opens the first ventilation hole, and the second damper closes the exhaust hole and operates the blower, indoor air is sucked into the duct from the first ventilation hole, and the second ventilation hole is closed. By ventilating the room into the room, indoor air can be circulated, and if a heat exchanger is operated at the same time, air conditioning can be achieved. In addition, the device of the present invention provides a duct by utilizing the internal space of the outer wall of the panel structure, and forms the first ventilation hole, the second ventilation hole, and the exhaust hole in the face plate of the outer wall, so that the duct can be connected between the attic and the indoor room. Since the duct can be communicated with the outdoors, there is no need to route the duct piping, making it easy to install and allowing the duct to be installed inconspicuously inside the house.
