BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation type indoor temperature control device using a combination of a blind and a curtain.

[0002]

2. Description of the Related Art Venetian blinds and curtains arranged on windowsills are shielding films for controlling light quantity, shading and protecting the privacy of a room. It is typically used for the purpose of reducing the air conditioning load during cooling and heating,
It was not always enough.

For example, in summer, even if the windows are closed for the purpose of blocking direct sunlight, the light transmitted through the window glass impinges on the blinds and curtain surfaces, and the heat of sunlight is reflected or absorbed by them, or the heat is transmitted to the window glass and the blinds. A portion of the high-temperature air that stays between the curtains and enters the room from there, and a portion of the air enters the room from near the ceiling surface, thereby raising the room temperature and causing a cooling load.

[0004] Further, when there is no solar radiation in winter, downdraft occurs due to a difference in temperature between the inside and outside of the window glass, and the feet near the window are extremely cold and the heating load is large.

[0005] In order to prevent these problems, conventionally, a window glass sash is doubled, a blind is incorporated between the sashes, indoor air is drawn from a lower portion of the inner glass, and connected to a return air duct behind the ceiling for ventilation. There has been proposed a ventilation type indoor temperature control device called a so-called air flow window.

[0006]

However, this type of ventilated room temperature control device is not only expensive, but also twice or three times as large as a normal single sash, and has disadvantages such as complicated maintenance. was there.

The purpose of the present invention is to solve the above-mentioned problem. The purpose of the present invention is to make it cheaper than a double sash structure, to make the heat load at the time of cooling and heating equal to that of an air flow window, and to use only ordinary blinds. In addition to the energy-saving effect, a ventilation type air conditioning system that can be used to minimize or minimize the use of window-type air conditioners such as fan coils used for general air conditioning, and further improves the indoor thermal environment near the windows Is provided.

[0008]

In order to achieve the above object, a ventilated room temperature controller according to the present invention includes a blind having a plurality of tiltable slats disposed on the indoor side of a window glass. , Which is further disposed on the indoor side of the blind so that it can be opened and closed and can be moved up and down, and when it is lowered, the window guard is opened.
And curtains to form a duct between the lath, and a curtain box which is arranged on the ceiling surface to accommodate the upper portion of blinds and curtains, openings for connection to the ceiling instead of the gas duct in the curtain box A part is formed.

[0009]

According to the above arrangement, a kind of sealed duct which generates a vertical airflow is formed by the space surrounded by the window glass and the curtain. The blind serves both as a light-shielding and light-amount adjusting and rectifying plate function according to the inclination angle of the slat.

When it is desired to keep the room temperature low, such as in summer, light rays are blocked by blinds to prevent radiant heat from entering the curtain as much as possible, and consequently radiant heat from entering the room. Further, the heat reflected and absorbed by the blinds is confined in the space surrounded by the window glass and the curtain and does not enter the indoor living area, so that the cooling load is minimized. In addition, indoor air-conditioned air is drawn from the lower part of the curtain, and is exhausted to the air return duct behind the ceiling through the curtain box behind the ceiling. As a result, the surface temperature of the curtain facing the interior of the room becomes extremely close to room temperature, and radiant heat is hardly received from a high-temperature blind as in a general case, so that a favorable indoor thermal environment can be obtained even at a window.

On the other hand, when it is desired to keep the interior warm, such as in winter, the interior is cooled by the window glass due to the difference between the inside and outside temperatures. While being mixed with the indoor air induced from the ceiling, the air is discharged outside from the ceiling return air duct through the curtain box behind the ceiling. Therefore, the heating load can be minimized, and the indoor surface temperature of the curtain is very close to room temperature as in summer, so that a favorable indoor thermal environment can be obtained.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. 1 and 2 show an indoor temperature controller according to the present invention. This room temperature controller
A window glass 3 fitted to a sash 2 provided at an opening of an outer wall 1 of a building, a venetian blind 4 hung down along the indoor side of the window glass 3, and a venetian blind 4 arranged along the indoor side of the blind 4. A lower part has a roll curtain 5 having an opening on the indoor side, and a curtain box 8 buried in the indoor ceiling surface 6 so as to protrude from the ceiling back 7, and inside the curtain box 8, the blind is provided. 4 and a retractor (winding tool) 10 for the roll curtain 5 are fixed. Further, the curtain box 8 is provided with an opening 11 with a shutter for connecting the air ventilating the space A with the room air drawn from the lower part of the curtain 5 to the air return duct 12 above the ceiling.

As is well known, a plurality of plastic slats 4a are vertically suspended at predetermined intervals by suspending cords 4b, and each of the slats 4a is arbitrarily operated by operating an angle adjusting cord (not shown). By inclining the angle, the amount of incident light can be adjusted, and the slats 4a can be pulled up on the lower surface of the support 9 in a stacked state and fully opened by operating a pulling cord.

The roll curtain 5 is transparent or translucent.
Various materials can be selected that have a strength that does not undulate due to passing air. In addition, a fixing device is provided at a lower portion of the integrated rod 5a for securing a necessary opening 5d for attracting appropriate room air by a pulling operation of the operating cord 5b hanging down to the center of the rod 5a. When it is not necessary, it can be rolled up in the retractor 10 and fully opened.

The curtain box 8 is provided with an opening 11 with a shutter which is connected to the air duct 12 above and below the ceiling. The shutter has a window glass and a roll curtain which surround the air drawn from the room. The purpose of the present invention is to adjust the amount of passing air along the glass surface so as to flow uniformly in the space.

FIG. 1 shows a state of use in a case where the apparatus is exposed to direct sunlight during cooling in summer, for example. When the roll curtain 5 is fixed to a predetermined place, a space A surrounded by the roll curtain 5 and the window glass 3 is shown. This forms a kind of duct that produces a vertical airflow. If the slats 4a of the blind 4 are inclined to the side opposite to the light incident side, the back of the blind is shielded from light, and the roll curtain 5 is hardly affected by the radiant heat due to the direct light. The heat reflected and absorbed by the blind 4 and the heat entering from the glass 3 due to the temperature difference between the inside and outside of the window glass surface rise while being mixed with the air-conditioned air induced from the roll curtain 5d in the space A, and the blind box 8 The air is exhausted from the shutter 11 to the air return duct 12 above the ceiling. As a result, the direct sunlight and the amount of heat flowing through from the window glass 3 are sealed in the space A, thereby reducing the cooling load of the indoor living area and achieving energy saving. Further, regarding the thermal environment of the window, the indoor surface temperature of the roll curtain 5 can be made extremely close to the indoor temperature without direct sunlight, so that the thermal environment of the indoor window can be improved.

On the other hand, FIG. 2 shows a case where it is desired to keep the room temperature warm when there is no direct sunlight during winter heating, and the roll curtain 5 is fixed at a predetermined place as in the summer to form a space A. The blind 4 is pulled up on the lower surface of the support 9 in a laminated state, and is fully opened. At this time, it is impossible for the cool air cooled by the temperature difference between the inside and outside of the window glass 3 to leak out from the roll curtain 5d, which is an opening to the room, due to the induced indoor air flow velocity, and further mixed with the induced indoor air-conditioned air. As a result, the surface temperature of the roll curtain 5 facing the room becomes extremely close to the room temperature, and the room thermal environment around the window becomes very good. If direct sunlight is present during winter heating, energy can be saved by returning air from the return air duct to the air conditioner.

[0018]

As described in detail in the above embodiments, in the room temperature controller according to the present invention, a kind of duct which generates a vertical airflow is formed by the space surrounded by the window glass and the curtain. Cooling air from the space does not leak to the room side from the opening at the lower part of the curtain that is open to the room due to the airflow velocity drawn from the room. In addition, the blind can perform light shielding and light intensity adjustment according to the inclination angle of the slat, and when light shielding is necessary, there is no direct sunlight on the back, so the curtain itself is not directly affected by direct sunlight ,
If unnecessary, it can be wound up in a curtain box in a laminated state. In addition, the blind has a structure that also functions as a current plate.

As described above, while maintaining the same thermal characteristics as a double sash with a built-in blind called an air flow window, which is effective for energy saving and improving the thermal environment of the window, a ventilated room temperature which is inexpensive and easy to maintain. It has become possible to realize an adjusting device. Moreover, the curtain rises
Because it can be opened and closed, it is suitable only for the lower end of the curtain.
