Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor air purification device incorporated in a wall of a building such as a house, and more particularly to an indoor air purification device for purifying and regenerating indoor air polluted with odors and dust.

[0002]

2. Description of the Related Art With the increase in the industrial production rate of buildings, the wall of a building such as a house is first assembled with an upper frame, a lower frame and a vertical frame to form a wall frame. In many cases, it is constructed by attaching wall materials to both the inside and outside of the wall framework. According to this type of construction method, a predetermined space is created inside the wall, which is partitioned by the upper frame, the lower frame, the left and right vertical frames, and the inner and outer wall members. Therefore, in recent years, for example, as described in Japanese Utility Model Laid-Open No. 55-57645,
The space inside the wall formed as described above is used as a circulation air duct for promoting convection of indoor air, or as a ventilation air passage for exchanging dirty indoor air with clean outside air. A circulating ventilation system has been proposed. In this circulation ventilation system, an air inlet and an outlet are provided in the lower part and the upper part of the indoor side wall surface, and a ventilation port is provided in the outdoor side wall surface, respectively. And the ventilation port are in communication with each other via an air passage in the wall (a space in the wall). A fan for blowing air and a fan motor for driving the fan are installed in the air passage in the wall.

The above-mentioned circulation ventilation system is used in response to the cooling and heating operation of a separately arranged air conditioner in summer or winter. That is, when the air-conditioning operation of the air conditioner is performed and the fan for blowing air in the air passage in the wall is operated, the indoor air is sucked from the suction port, and the sucked indoor air rises (or falls) in the air passage in the wall. After being guided to the air outlet, it is again blown out into the room from the air outlet. As a result, mechanical convection is promoted and the room air is further agitated, so that a comfortable temperature and humidity environment is spread to every corner of the room. In addition, since the above-mentioned circulation ventilation system is installed in the wall as a part of the wall, the interior of the wall is not narrowed, and therefore it does not become an obstacle and does not spoil the aesthetics of the room. Have

[0004]

By the way, since the circulation ventilation system having the above-mentioned conventional structure is not provided with the damper at the ventilation port, the adjusted air in the room is exhausted as it is, and the cooling and heating efficiency in the room is deteriorated. Was invited. In order to solve the problem of lowering the cooling and heating efficiency, it is conceivable to provide a damper at the ventilation port and install a drive control device that selectively controls the ventilation operation mode and the circulation operation mode. However, by installing the drive control device and the damper, even if the problem of cooling and heating efficiency is solved, when a bad odor or dust occurs in the room during the circulation operation of the room air,
It is not possible to quickly remove the offensive odors and dust generated while maintaining the heating and cooling conditions. (Switching to ventilation operation mode can normally remove the offensive odors and dust, but this does not improve the cooling and heating conditions. Therefore, the cooling and heating efficiency will be reduced.) Therefore, in recent air-tightened houses, for example, the smell and smoke of cigarettes stay in the room forever, and the discomfort of residents is only aggravated. On the other hand, the ventilation operation in the area where the outside air is more permanently polluted than the indoor air results in the invasion of pollutants, and the ventilation has the opposite effect. Even in the suburbs where the air is clean, it can happen that the outside air is contaminated with bad odors and dust due to accidental temporary factors, and once it is contaminated, ventilation is required until the outside air returns to its original clean state. Cannot be done.

The present invention has been made in view of the above circumstances, and is a wall-embedded indoor air purifying device having a function of purifying and regenerating indoor air polluted with odors and dust without relying on ventilation. Is intended to provide.

Next, the operation of the indoor air purifying device having the above structure will be described. Figure 5 shows the building unit (Figure 1)
It is an indoor scene map of a residential room part in which is incorporated.
In this room, a wall-mounted room air conditioner R is provided in addition to the indoor air purifying device incorporated in the wall portion. [A] Circulating Operation Now, assume that a bad odor and a large amount of smoke are contained due to being inside the room during a heating operation (or a cooling operation) of the room air conditioner R. In this scene, a person operates the operation panel 72 to turn on the power of the indoor air purification device of this example and sets the operation mode to the circulation operation mode.

When power is supplied and the circulation operation mode is set, the control section 71 controls the suction motor and the blowing motor to control the suction fan 41 and the blowing fan 4.
Start 2 and turn it into a rotating state. Further, as shown in FIG. 3, the opening / closing drive of the discharge control electric damper 61, the intake control electric damper 62, and the wind path dividing electric damper 63 is controlled to discharge the exhaust louver (opening for discharging indoor air). 34 and the intake louver (opening for outside air intake) 36 are closed, while the air passage D in the wall is opened. As a result, the indoor air polluted by the foul odor and smoke will be discharged into the suction fan 41.
Is mainly sucked into the air passage D in the wall through the suction louver 31, and first, the deodorizing and dust collecting filter 5 in the front stage is
It is filtered by No. 1 to remove bad smell and smoke. The air purified by the deodorizing and dust collecting filter 51 is
The inside air passage D in the wall rises from the floor portion side to the ceiling portion side, and is filtered again by the deodorizing and dust collecting filter 52 in the subsequent stage by the main function of the blowing fan 42. By this re-filtration,
The air that has risen in the air passage D in the wall is purified more reliably and returned to the room from the blowout louver 32. In this way, when the indoor air purification device of this example is operated in the circulation operation mode, the contaminated indoor air is forcibly recirculated and filtered, so that foul odors and smoke can be quickly generated even without relying on ventilation. Can be removed. Therefore, the heating state (or the cooling state) of the room is not deteriorated.

[B] Ventilation operation At the time of oxygen deficiency, a person operates the operation panel 72,
The indoor air purification device is turned on and the operation mode is set to the ventilation operation mode. When the power is supplied and the ventilation operation mode is set, the control unit 71
By controlling the suction motor and the blowing motor, the suction fan 41 and the blowing fan 42 are started and brought into a rotating state. Further, as shown in FIG. 4, the opening / closing drive of the discharge control electric damper 61, the intake control electric damper 62, and the wind path dividing electric damper 63 is controlled to open the discharge louver 34 and the intake louver 36. Meanwhile, the air passage D in the wall is closed at its intermediate portion. As a result, the air passage D in the wall is divided into a lower indoor air discharge passage and an upper air introduction passage.

Therefore, the oxygen-deficient indoor air is sucked into the air passage D in the wall through the suction louver 31 by the action of the suction fan 41, passes through the deodorizing and dust collecting filter 51, and then the discharge louver 34. Is discharged outdoors. On the other hand, by the action of the blowing fan 42, the outside air is taken into the air passage D in the wall via the intake louver 36, and the deodorizing and dust collecting filter 52 is provided.
Be led to. Then, the bad odor and smoke are removed (depending on the degree of pollution of the outside air), and the air is introduced into the room as fresh outside air from the blowout louver 32.

As described above, according to the configuration of this example, even the outside air contaminated with a bad smell and dust is introduced into the room after being purified by the deodorizing and dust collecting filter, so that comfortable ventilation can be performed. it can. In addition, the contaminated indoor air is discharged after the bad odor and dust are removed by the deodorizing and dust collecting filter 51, so that it does not disturb the neighborhood.

As a modified example of the first embodiment, the intake fan operation mode is set in which only the blowing fan 42 is operated to perform only the intake operation of the outside air, and only the suction fan 41 is operated to be contaminated. It is also possible to adopt a configuration in which an exhaust operation mode in which only indoor air exhaust operation is performed can be set.
Both of these modes can be set instead of the above-mentioned ventilation operation mode or in addition to the ventilation operation mode. Further, a room air diversion mechanism may be provided so as to partially recirculate and partially discharge (ventilate) in the air passage in the wall.

As another modification of the first embodiment, as shown in FIG. 6, an exhaust louver (opening for indoor air exhaust) 34, an intake louver (opening for external air intake) 36, etc. The configuration may be simplified by omitting. In the configuration shown in FIG. 6, ventilation must be performed by another means, but the indoor air contaminated with bad odors and dust can be purified and regenerated quickly without impairing the heating and cooling conditions.

Second Embodiment Next, a second embodiment of the present invention will be described. 7 and 9 are vertical cross-sectional views showing a schematic configuration of an indoor air purification apparatus according to a second embodiment of the present invention, and FIG. 8 is a in FIG.
-A line, b-b line, cc line, d-d line and ee line cross-sectional view along line, respectively, FIG. 10, a'-a 'line of FIG.
It is a transverse cross section which each follows the b'-b 'line, the c'-c' line, the d'-d 'line, and the e'-e' line. The indoor air purifier of this example is greatly different from that of the above-described first embodiment in that the heat exchanger 8 for exchanging heat between the exhausted indoor air and the introduced outside air during the ventilation operation is used. This is a point provided in the wind passage D in the wall of the girder side wall panel. In addition,
7 and 9, the same components as those of the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

The heat exchanger 8 is made of a rectangular tube made of a copper plate or an aluminum plate. As shown in FIG. 8, a comb-shaped partition wall 81 is inserted inside the heat exchanger 8 and is discharged through the suction louver 31. An indoor air exhaust passage 82 for guiding the indoor air to the exhaust louver 34 and an external air introduction passage 83 for guiding the external air introduced from the intake louver 36 to the blowout louver 32 are provided. Here, the comb-shaped partition wall 81 functions as a heat exchange medium, and as shown in the figure, it has a bent shape with a comb-shaped cross section, thereby expanding the chances of contact between room air and the outside air. It is designed to enhance heat exchange efficiency.

In this example, since the heat exchanger 8 is added, the positional relationship between the opening for discharging indoor air and the opening for taking in outside air is replaced with that of the first embodiment. That is, in the first embodiment, the opening for discharging indoor air, the discharge louver 34 with the eaves 33 corresponding thereto, the electric damper 61 for discharge control, and the like are provided in the vicinity of the lower end on the outdoor side of the air passage D in the wall. However, in this example, it is provided in the vicinity of the outdoor upper end portion of the in-wall wind passage D.
On the other hand, the opening for intake of outside air and the intake louver 36 with the eaves 35 corresponding thereto, the intake control electric damper 62, etc.
In the first embodiment, it is provided near the outdoor-side upper end portion of the in-wall air passage D, but in this example, it is provided near the outdoor-side lower end portion of the in-wall air passage D.

In the heat exchanger 8, the indoor air exhaust passage 8
One end (open end) of 2 is arranged at a position near the lower end of the in-wall air passage D and communicates with the suction louver 31. Also,
The other end (open end) is connected to the discharge louver 34 via the discharge control electric damper 61. On the other hand, one end (opening end) of the outside air introduction passage 83 has an intake control electric damper 6
It is connected to the intake louver 36 via 2. Also,
The other end (opening end) is arranged at a position near the upper end of the in-wall air passage D and communicates with the blowout louver 32.

An area other than the area occupied by the heat exchanger 8 in the middle portion of the air passage D in the wall is an indoor air recirculation path Da, and a ventilation operation is performed at an intermediate portion of the indoor air recirculation path Da. An electric damper 64 for shutting off the air passage is provided for shutting off and closing the air passage D in the wall at the intermediate portion in the mode.

Next, the operation of the indoor air purifying device having the above structure will be described. [C] Circulation Operation In the same configuration as that shown in FIG. 5, when the power is supplied and the circulation operation mode is set, the control unit controls the suction motor and the blowing motor to control the suction fan 41.
And the blowing fan 42 is started to bring it into a rotating state. Further, as shown in FIG. 7 and FIG. 8C, the opening / closing drive of the discharge control electric damper 61, the intake control electric damper 62, and the air passage blocking electric damper 64 is controlled to control the indoor air discharge passage 82. And the outside air introduction passage 83 are closed, while the indoor air return passage Da is opened.

As a result, the indoor air polluted by the foul odor and smoke is sucked into the air passage D in the wall via the suction louver 31 by the main function of the suction fan 41, and first, the deodorant collection in the preceding stage is performed. The dust filter 51 filters the odor and smoke. Deodorant dust filter 51
The air purified by the ascends from the floor side to the ceiling side in the indoor air recirculation path Da (FIGS. 8A to 8E), and the main function of the blow-out fan 42 serves to eliminate the air in the latter stage. It is filtered again by the odor dust filter 52. By this re-filtration, the air that has risen in the indoor air recirculation path Da is purified more reliably and returned to the room from the blowout louver 32. 8 (a) to 8 (e), the arrow ↑ indicates
It shows that the air flow is generated from the floor side toward the ceiling side. As described above, when the indoor air purification device of this example is operated in the circulation operation mode, the same effect as in the case of the circulation operation mode in the first embodiment can be obtained.

[D] Ventilation operation At the time of oxygen deficiency, a person operates the operation panel to turn on the power of the indoor air purification device and sets the operation mode to the ventilation operation mode. When the power is supplied and the ventilation operation mode is set, the control unit controls the suction motor and the blowing motor to start the suction fan 41 and the blowing fan 42 to bring them into a rotating state. Further, as shown in FIGS. 9 and 10 (c '), the opening / closing drive of the discharge control electric damper 61, the intake control electric damper 62, and the wind passage blocking electric damper 64 is controlled to control the indoor air discharge passage. 82 and the outside air introduction passage 83 are opened,
The indoor air return passage Da is closed.

From this, the room air in the oxygen-deficient state passes through the suction louver 31 by the action of the suction fan 41,
The air is sucked into the air passage D in the wall, and is guided to the indoor air exhaust passage 82 through the deodorizing and dust collecting filter 51. Then, the air is exhausted to the outside from the exhaust louver 34 through the inside air exhaust passage 82 (Fig. 10 (a ') to Fig. 10 (e')). On the other hand, by the action of the blowing fan 42, the outside air is taken into the inside air passage D through the intake louver 36, and further passes through the outside air introduction passage 83 to the deodorizing and dust collecting filter 52. Be guided. Then, the bad odor and smoke are removed (depending on the degree of pollution of the outside air), and the air is introduced into the room as fresh outside air from the blowout louver 32. At this time, the outside air flowing through the outside air introduction passage 83 is
Heat is exchanged with the room air flowing through the room air discharge passage 82 through the comb-shaped partition wall 81 (FIG. 10 (a ′) to FIG.
(e ')). 10 (a ') to 10 (e'), the arrow ↑ indicates that the air flow is generated from the floor side toward the ceiling side.

As described above, according to the configuration of this example, the first
The same effect as described in the embodiment can be obtained. In addition, in ventilation during heating, with the help of the heat exchanger, the preheated outside air flows into the room from the warm indoor air discharged, so that it is possible to reduce the deterioration of the heating efficiency or the deterioration of the heating state. Similarly, in the ventilation during cooling, with the help of the heat exchanger, the outside air precooled by the discharged cold room air flows into the room, so that the reduction of the cooling efficiency or the deterioration of the cooling state can be reduced. Note that some of the modified examples described in the first embodiment are

Furthermore, as shown in FIG. 12, the opening / closing drive of the discharge control electric damper 61, the intake control electric damper 62, and the wind path dividing electric damper 63 is controlled to open the discharge louver 34 and the intake louver 36. Meanwhile, the air passage D in the wall is closed at its intermediate portion. As a result, the air passage D in the wall is divided into a lower indoor air discharge passage and an upper air introduction passage.

As a result, the oxygen-deficient indoor air is sucked into the air passage D in the wall via the suction louver 31 by the action of the suction fan 41, passes through the deodorizing and dust collecting filter 51, and then the discharge louver 34. Is discharged outdoors. On the other hand, by the action of the blowing fan 42, the outside air is taken into the air passage D in the wall via the intake louver 36, and the deodorizing and dust collecting filter 52 is provided.
Be led to. Then, the bad odor and smoke are removed (depending on the degree of pollution of the outside air), and the air is introduced into the room as fresh outside air from the blowout louver 32. As described above, when the indoor air purification device of this example is operated in the ventilation operation mode, the same effect as in the ventilation operation mode of the first embodiment can be obtained.

As a modified example of the third embodiment, an air conditioner indoor unit having a humidity adjusting function may be provided in the air duct in the wall instead of or in addition to the above temperature adjusting function. May be. Further, the air conditioner indoor unit may be provided not only in the air passage in the wall but also in the vertically long space in the adjacent wall.

As another modification of the third embodiment, a simple structure may be adopted in which the exhaust louver (opening for indoor air exhaust) 34, the intake louver (opening for external air intake) 36, etc. are omitted. good. With such a configuration, although ventilation must be performed by another means, it is possible to quickly perform purification / regeneration of indoor air contaminated with bad odors and dust. There is no need to separately deploy an air conditioner as shown in FIG.
There is also the effect of making the room spacious.

As yet another modification of the third embodiment, the outside air introduced during the ventilation operation may be heated or cooled by this type of air conditioner indoor unit.

Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific structure is not limited to this embodiment, and there are design changes and the like within the scope not departing from the gist of the present invention. Also included in the present invention. For example, instead of the louver, a grill may be fitted in each opening of the air passage in the wall. Further, not only the wall panel on the girder side but also the wall panel on the gable side may be incorporated with the indoor air purifying device of the present invention. Further, instead of the suction fan and the blow-out fan capable of only normal rotation, a suction blow-out fan capable of both normal rotation and reverse rotation is used, so that the recirculation direction of the indoor air can be appropriately changed. Further, either one of the suction fan and the blowing fan can be omitted as necessary. Further, each electric damper may use either an electric actuator or a hydraulic actuator as long as the actuator is electrically controlled.

In order to ensure waterproofness in the wall,
The inner surface of the air passage in the wall may be covered with a waterproof sealing material. Further, in the above-mentioned embodiment, the case where the vertically long space in the wall is used as it is as the air passage in the wall is described. The duct may be housed in a vertically long space in the wall for use. Alternatively, the non-combustible duct or the blower pipe may be provided only in a part of the vertically long space in the wall (for example, in the vicinity of the opening for intake of indoor air or the opening for intake of outside air).

Further, the present invention is not applied only to a wall portion of a building formed by a wall-type construction method (where a chimney-shaped vertically long space portion is generated in the wall) or a construction method similar to the wall-type construction method. The present invention can be applied even to a wall portion formed by a construction method in which a vertically long space portion does not occur, as long as it has a thickness that allows an existing duct to be buried.

Further, the deodorant dust collecting filter is not limited to the sheet type, but may be a granular type, a non-woven type or a cotton type.
Further, the deodorizing and dust collecting filter is not limited to the laminated composite of the deodorizing filter and the dust collecting filter, and may be made of a single material having both deodorizing property and dust collecting property. The deodorizing and dust collecting filter of the present invention includes a case where the deodorizing filter and the dust collecting filter are separately arranged with a predetermined distance from each other. When the deodorizing filter and the dust collecting filter are separately arranged, the malodor (dust) is first removed, and then the
Dust (bad smell) will be removed, but in the end,
This is because the laminated composite of the deodorizing filter and the dust collecting filter has the same function and effect in that both the bad odor and the dust are removed.

Further, in the above-described embodiment, the deodorizing and dust collecting filter is provided on the downstream side (immediately rearward) of the suction fan, but it is provided on the upstream side (immediately forward) of the suction fan. You can In this way, the deodorant dust collecting filter can be easily replaced. Similarly, in the above-described embodiment, the deodorant dust collecting filter is provided on the upstream side (immediately rearward) of the blowing fan, but is provided on the downstream side (immediately forward) of the blowing fan. Is also good.
