Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an energy-saving indoor air circulating device which is designed to raise the temperature by diffusing indoor air.

[0002]

2. Description of the Related Art Generally, heating equipment is used to raise the temperature in a room such as a house. However, when the heating device is used, naturally, energy for heating (for example, oil, city gas, electric energy, etc.) is required. Further, depending on the heating method, the temperature distribution often becomes unevenly distributed in the room.

Further, such uneven distribution of temperature distribution is caused by the structure of the room. For example, in the east-facing or south-facing windows, even in winter, sunlight is taken in sufficiently during fine weather, so the temperature near the windows becomes high. On the other hand, in the north-facing window, the outside air is transmitted through the window, and the temperature near the window tends to be low.

For this reason, even in the conventional heating equipment, for example, an air conditioner or the like is provided with a blowing means to diffuse and circulate the air in the room. However, this is a separate structure in the room, especially a window or the like. Not considering the relationship with
It simply circulates the air in the room. As a result, the room temperature can be made uniform to some extent.

[0005]

However, in the above-mentioned conventional method, the operation of the heating equipment itself is a prerequisite, and since no attention is paid to the indoor structure, particularly the position of windows, etc. It was difficult.

On the other hand, the present inventor has
Pay particular attention to the position of the windows, and for example, from the sunrise to the daytime, the indoor air temperature around the windows rises in the eastward or southward direction, so this is actively diffused indoors. By circulating it, the indoor temperature was made uniform.
At the north-facing window, we focused on the outside air (cold air) and made it difficult for this cold air to propagate into the room so that the room temperature could be made uniform. Furthermore, even if the window is facing east or south, the outside air is still a problem on a cloudy day or at night, so the same approach was taken as for the window facing north.

The present invention has been made in view of such an idea, and basically, the air heated in the vicinity of the window in the room is positively utilized, while conversely, the air from the vicinity of the window is also used. It is intended to provide an indoor air circulation device that effectively prevents the cold air from propagating to the inside of the room and makes the indoor temperature uniform.

[0008]

According to a first aspect of the present invention, there is provided an air suction section installed in a high temperature distribution region of a room where temperature distribution is unevenly distributed, and an air blower installed on the floor side of the room. And an air-blowing tube arranged between the air suction section and the air blowing section, and the air suction section includes an air suction fan.

The present invention according to claim 2 is characterized in that the high temperature distribution region in the room where the air suction part is installed is near the ceiling of the room or near the hot air blowing part of the heating device. In the indoor air circulation device described.

According to a third aspect of the present invention, the air blowing portion is a horizontally long box body, and the front portion thereof has an upper air temporary storage chamber and a lower air blowing chamber partitioned by an insole. And a rear part is provided with an air blowout partition part partitioned by a plurality of partition plates, while the air from the blower tube is stored in the temporary air storage chamber, while the air blowout chamber is provided with the middle bottom. The air from the air temporary storage chamber is introduced by the ventilation holes opened at appropriate intervals, and further, the air from the blowout holes opened in the air blowout chamber is blown to the air blowout compartment. The indoor air circulation device according to claim 1 or 2.

According to a fourth aspect of the present invention, there is provided the indoor air circulation device according to the third aspect, wherein the vent holes of the temporary air storage chamber and the blow holes of the air blowing chamber are displaced from each other.

[0012]

1 to 4 show an embodiment of an indoor air circulation device according to the present invention. 10 in the figure
Is an air suction unit, 20 is an air blowing unit, and 30 is an air suction unit 1.
It is a blower tube that is piped between 0 and the air outlet 20.

For example, in the room 100 shown in FIGS. 1 and 2, when the window 110 (a glass window at the entrance or the like is also possible) faces east or south, it is near this window when it is lit from sunrise on a sunny day during the day. The temperature of the indoor air is raised. This is empirically clear.

Therefore, the air suction part 10 is installed on the ceiling part near the window 110, while the air blowing part 20 is installed on the floor side near the window 110. As shown in FIG. 2, the air suction section 10 includes an air suction fan 13 which is rotated by an electric motor 12 in a housing 11. Therefore, when the air suction fan 13 is rotated by the electric motor 12, the air near the ceiling is sucked and the blower tube 30 is blown.
And is sent to the air blowing unit 20. It should be noted that it is preferable to install a dust collecting filter 14 on the air intake side of the housing 11.

That is, according to the present invention, in the room 100 in which the temperature distribution is unevenly distributed, the air suction portion 10 is installed in a high temperature distribution region such as near the ceiling.

As is apparent from the enlarged views of FIGS. 3 to 4, the air blowing portion 20 has a horizontally long box body 21 as a whole.
The front portion (inside the room in the figure) is provided with the upper air temporary storage chamber R1 and the lower air outlet chamber R2 partitioned by the insole 22, and the rear part (the window side in the figure) has a plurality of Partition plate 23
It is provided with an air blow-out partition section R3 partitioned by.

Further, the inner bottom 22 of the air temporary storage chamber R1
In this case, for example, every other small ventilation hole 22a is provided for each of the plurality of air blowout partition portions R3 on the back side. Therefore, the air supplied through the blower tube 30 is once uniformly filled in the temporary air storage chamber R1,
After being stored, as shown in FIG. 3, it is introduced into the lower air blowing chamber R2 side through the ventilation hole 22a. That is, with this configuration, the air is introduced into the air outlet chamber R2 side in a substantially evenly distributed form.

In the air blow-out chamber R2, a plurality of air blow-out compartments R3 on the back side are displaced from the air holes 22a by one, and the inside of the air blow-out compartment R3 is the same. The plate 24 is provided with a small blowout hole 24a. As a result, the air from the ventilation hole 22a is divided into, for example, the left and right blowout holes 24a, 24a as shown in FIG. 3, and is guided to the corresponding air blowout section R3 on the back side through a longer path. . The longer this path is, the more efficiently the air is warmed. That is, this is because the air blowing unit 20 itself is installed in the temperature rising region of the window 110.

Here, more preferably, as shown in FIG. 4, an upward air receiving piece 25 may be provided on the air outlet section R3 side of the outlet hole 24a. This allows
The air blown out from the blowout hole 24a is effectively raised due to the interaction with the stack effect on the air blowout section R3 side.

That is, on the side of the air outlet section R3, which is continuously arranged on the side of the window 110, its back plate 26 is
Since it is heated by the temperature-increased air around 10 and sunlight, the air introduced into this becomes a thin air curtain state from the upper opening and is blown out into the room as an ascending air current. And it reaches the ceiling side. Even during this rising, the temperature is raised more smoothly without waste because it is heated by the heated air or sunlight near the window 110.

In addition, in the air blowing section R3,
If there is no blowout hole 24a, the bottom side is opened. Then, the heated air near the window 110 becomes
The air is blown up through the air blow-out partition R3 that penetrates vertically. There may be a difference between opening and closing in the side having the blowout hole 24a. If left open, outlet 24a
In addition to the air blown from the above, the heated air near the window 110 is also blown into the room together with the air without the blow holes 24a, and a greater air circulation effect is obtained. Of course, when it is closed, the air blown out from the blowout hole 24a is blown out mainly.

In any case, the air thus reaching the ceiling side is sucked by the above-mentioned air suction portion 10 and supplied again to the air blowing portion 20. By repeating this, an effective heating effect can be obtained from the sunrise to the daytime.

Moreover, in the present invention, since the air circulation is performed only by the rotation of the electric motor 12 of the air suction portion 10,
It is possible to raise the temperature with only a small amount of motor rotation energy. That is, it is possible to realize excellent energy-saving heating.

5 to 6 show another embodiment of the indoor air circulation device according to the present invention. In this case, when the window 110 of the room 100 faces north, the air blow-out section 20 is installed near this window 110, and the air suction section 10 is installed near other heating devices 200. is there.

In the room 100 having such a structure, the outside air is cold in winter and the like, so that if the cold air is transmitted to the room 100, the room temperature is lowered. Therefore, in the present invention, the air suction unit 10 sucks the heated air from the heating device 200 and introduces it into the air blowing unit 20 through the blower tube 30. Then, in the same manner as described above, a plurality of air blowout sections R of the air blowout section 20 are arranged.
From 3, it blows up near the window 110 and goes up and down. Since this rising airflow exhibits a kind of air curtain effect, the propagation of cold outside air into the room 100 is effectively blocked.

FIG. 7 shows still another embodiment of the indoor air circulation device according to the present invention. In this case,
As in the case of FIG. 2, the air outlets 20 are installed near the windows 110 facing east or south, while the air suction parts 10 are installed at two locations on the ceiling side and the heating device 200 side, and a sunrise on a clear day is provided. During the daytime, the air suction unit 10 on the ceiling side is operated. Then, the same heating effect as in the case of FIGS. 1 and 2 can be obtained. On the other hand, when the weather is a cloudy day, a snowy day, or night, the air suction unit 10 on the heating device 200 side is operated. Then, the propagation of cold outside air into the room 100 is effectively prevented, and as a result, a good heating effect is obtained.

In each of the above-described embodiments, a large number of partition plates 23 are used to form the air blowout partition R3, but the present invention is not limited to this. For example, as shown in FIGS. 8 to 9, this portion may be configured as a honeycomb structure 40.

That is, in the honeycomb structure 40 of FIG.
Middle plate 24 of upper and lower air temporary storage chambers R1 and air outlet chambers R2
On the other hand, a thin plate 41 bent into a curved shape is additionally provided, and as a result, a large number of cylindrical portions extending in the up-down direction serve as air blowout partition portions R3. On the other hand, the honeycomb structure 4 of FIG.
In 0, the bent thin plate 42 and the outer shielding plate 43 are attached to the middle plate 24 of the upper and lower air temporary storage chambers R1 and R2, whereby a large number of vertically extending parts are provided. The rectangular tube portion becomes the air blowout partition portion R3. In any case, with this honeycomb structure, the contact area with air becomes larger, so that a more excellent temperature raising effect can be obtained.

[0029]

According to the present invention described above, the following effects can be obtained. (1) First, the indoor air circulation device of the present invention can be provided at a low cost because the basic structural part has a simple structure including an air suction part, an air blowing part, and a blower tube.

(2) Further, it is possible to downsize each component. That is, since the air suction unit merely circulates the indoor air, a small electric motor can sufficiently cope with it, and the overall size can be reduced. Since the air blowing portion is also configured to only optimally distribute and blow out the air, it can be made thin and compact. Of course, the blast tube does not have to be so thick, and a relatively thin one can be used.
Therefore, it occupies a small volume and can be installed in an inconspicuous form in the room.

(3) In particular, paying attention to the structure of the room, the air outlet is installed near the window, while the air suction portion is located near the ceiling of the room or near the hot air outlet of the heating equipment. When the windows are installed facing east or south, the temperature inside the room can be made uniform by simply operating the air suction section from the sunrise to the daytime. That is, excellent energy saving can be achieved. On the other hand, even when the windows are facing east or south, on a cloudy day, a snowy day, or at night, or when the windows are facing north, the indoor temperature can be made uniform by combining with the heating device. . That is, since the hot air on the heating device side is only partially used, excellent energy saving can be achieved.

(4) The air blow-out part is a horizontally long box body, and the front part thereof is provided with an upper air temporary storage chamber and a lower air blow-out chamber partitioned by an insole, and at the rear part. It is equipped with an air blow-out partition section divided by a plurality of partition plates, while the air from the blower tube is stored in the temporary air storage chamber, while the air blow-out chamber is provided with air holes provided at appropriate intervals in the inner bottom. When the air is introduced from the temporary storage chamber and further the air is blown from the blowout holes opened in the air blowing chamber to the air blowing compartment, a plurality of air blowing compartments are arranged in series. Therefore, the air is optimally distributed, and there is an advantage that the air is blown out uniformly as a thin curtain state.

(5) When the positions of the vent holes of the temporary air storage chamber of the air blowing portion and the positions of the blowing holes of the air blowing chamber are shifted, the moving path of the air becomes long and a good temperature raising effect can be obtained.
