[0006]

Next, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a configuration diagram of a positive pressure air supply purifier 1 of the present invention. The positive pressure air supply purifier 1 of the embodiment is attached to a house (not shown), and forcibly introduces outside air into the room to increase the room pressure (positive pressure) from the outside pressure.
It has a function to prevent harmful substances such as pollen or dioxin from entering the room through the gaps in the house, a function to clean indoor air, and a function to humidify indoor air. It comprises a one-motor, two-fan type fan 8, a moisture adsorption element 2, and dampers 9A, 9B as air path switching means.

The fan 8, the moisture adsorbing element 2, the dampers 9A and 9B, and the like are provided in a housing having a predetermined air passage (not shown), and are mounted on a wall of a house (not shown). The fan 8 drives the outside air fan and the inside air fan at the same time by one motor. However, the present invention is not limited to this, and the outside air fan and the inside air fan may be configured separately by motors. .
The fan 8 has an outside air blowing capacity of at least 50 cubic meters / h. As a result, the interior of a normal house can be set at a positive pressure as described later.

A two-layer pipe 12 is connected to the housing, and the two-layer pipe 12 is attached so as to penetrate an outer wall (not shown) of the house, and communicates between the room and the outside. A partition plate 15 is provided in the double-layer pipe 12 to partition the inside into two parts in the longitudinal direction. The partition plate 15 has an intake hole 12A on one side and an exhaust hole 12B on the other side. . Inlet 1
2A is connected to the outside air suction side of a fan 8 through an air filter 3 for removing relatively large dust and the like contained in the outside air. The fan 8 removes the outside air through an intake hole 12A and the air filter 3. It is configured to suck.

The outside air discharge side of the fan 8 is connected to a damper 9.
A, and this damper 9A is connected to a first
Through the moisture adsorbing element 2 through the air passage, and communicates with an exhaust hole 12 </ b> B provided in the double-layer pipe 12. That is, by the damper 9A, the outside air sucked by the fan 8 from the intake hole 12A of the two-layer pipe 12 through the air filter 3 passes through the damper 9A and the moisture adsorption element 2 to the outside from the exhaust hole 12B of the two-layer pipe 12. An exhaust air path is formed.

The moisture adsorbing element 2 has a disk shape with a predetermined thickness, and is driven by a motor (not shown) as shown in FIG.
It is driven so as to rotate about half a clockwise (in the direction of the arrow) in the middle half a minute. The moisture adsorbing element 2 adsorbs moisture contained in the air when the air passes therethrough, and the adsorbed moisture is converted into heated air by the heated air passing through the moisture adsorbing element 2. It has a delivery function to absorb moisture.

An air passage provided around the moisture adsorbing element 2 rotated by the electric motor is partitioned by a region partition plate 2A, and is divided into the first air passage, the second air passage, and the third air passage. Three air passages are formed, and the portion of the moisture adsorbing element 2 located in the first air passage is a moisture adsorbing region 4, the portion of the moisture adsorbing element 2 located in the second air passage is a preheating region 5, and the third air passage is a third air passage. The portion of the moisture adsorbing element 2 located in the air passage is defined as a humidifying region 6.

Focusing on a certain portion of the moisture adsorbing element 2, the portion is moved from the moisture adsorbing region 4 to the humidifying region 6 by being rotated by the electric motor, and then moves to the preheating region 5 to again adsorb the moisture. The cycle of returning to region 4 is repeated.

The second air passage communicates with the inside air discharge side of the fan 8 via a damper 9B. The inside air suction side of the fan 8 is communicated with the room through the filter 21, and the air in the room is sucked by the fan 8. And
The sucked room air temporarily passes through the preheating area 5 of the moisture adsorption element 2 from the second air passage. The room air is preheated in the preheating area 5. Then, after once leaving the moisture adsorbing element 2 and heated by the electric heater (PTC heater) 7, it passes through the humidifying region 6 of the moisture adsorbing element 2, and then passes through the filters 22 and 23 from the third air passage. , So as to return to the room.

The filter 21 removes relatively large dust, similarly to the filter 3 described above. On the other hand, the filter 22 is, for example, a HEPA filter for removing harmful substances such as pollen and dioxin, and the filter 23 is formed of a deodorizing filter for removing odor.

Next, the operation of the positive pressure air purifier 1 having the above configuration will be described. The positive pressure air purifier 1 is configured to be able to select a positive pressure air supply / air cleaning mode and a humidification mode. It shall be executed by a control device that does not.

First, the humidification mode of the positive-pressure air purifier 1 will be described with reference to FIG. This humidification mode is effective when executed in winter, for example, from December to March.
In this case, the control device includes the fan 8 and the moisture adsorption element 2
And controls the dampers 9A and 9B to communicate the outside air discharge side of the fan 8 with the first air passage.
Then, the inside air discharge side of the fan 8 communicates with the second air passage, and the electric heater 7 generates heat.

As described above, the outside air is sucked from the intake hole 12A of the double-layer pipe 12 by the operation of the fan 8. The sucked air passes through the first air passage and the moisture adsorption area 4 of the moisture adsorption element 2 by the damper 9A, and the exhaust hole 12B of the two-layer pipe 12
(Indicated by a white arrow 14 in the figure). At this time, the moisture contained in the outside air is adsorbed by the moisture adsorbing element 2 in the portion that is the moisture adsorbing area 4 and is conveyed to the humidifying area 6 by rotation by the electric motor.

On the other hand, the room air sucked by the operation of the fan 8 once passes through the moisture adsorbing element 2 from the second air passage and the preheating area 5 of the moisture adsorbing element 2 by the damper 9B, and is heated by the electric heater 7. Thereafter, the air returns to the room through the humidification area 6 of the moisture adsorption element 2. At this time, the indoor air (indicated by a solid arrow 13 in the figure) returns to the room after receiving the moisture adsorbed by the moisture adsorption element 2 in the moisture adsorption area 4 in the humidification area 6 of the moisture adsorption element 2. .

That is, the moisture adsorbed on the moisture adsorbing element 2 in the moisture adsorbing area 4 is conveyed to the humidifying area 6 by the rotation of the moisture adsorbing element 2, where it is preheated in the preheating area 5, and furthermore, by the electric heater 7. It is absorbed by the heated room air and finally transported into the room. Thereby, the room is humidified. In the residual heat area 5, the room air before reaching the electric heater 7 is preheated and the water adsorption element 2 itself is cooled by the moisture adsorbing element 2 whose temperature is increased by the room air heated by the electric heater 7. As a result, the efficiency is improved.

As described above, in the humidification mode of the positive pressure air purifier 1, the moisture in the outside air taken in by the fan 8 is received by the moisture adsorption area 4 of the moisture adsorption element 2 and is circulated by the fan 8. Since the indoor air is humidified in the humidification area 6 and, as a result, the room is humidified, it is not necessary to supply water as in the case of a room humidifier using a normal humidifier, which is extremely convenient. . Then, the filters 22 and 23 also clean the indoor air.

Next, the positive pressure air supply / air cleaning mode of the positive pressure air supply purifier 1 will be described with reference to FIG. This positive pressure air supply / air cleaning mode is effective when executed during a period from April to November, for example. In this case, the control device similarly drives the fan 8 and controls the dampers 9A and 9B to control the outside air discharge side of the fan 8 and the filter 22 and the fan 8
The air passage between the inside air discharge side and the filter 22 is communicated.

The operation of the fan 8 causes the double-layer tube 1 to operate.
Outside air is sucked from the second air inlet 12A, and the sucked outside air is sequentially supplied to the room through the filters 22 and 23 via the damper 9A (open arrow 14 in the figure). When the outside air passes through the filters 22 and 23, harmful substances such as pollen and dioxin contained therein are removed to become clean air, which is taken into the room. In addition, due to the forced air supply, the indoor air pressure is higher than the external air pressure and becomes a positive pressure, so that the external air entering from the gaps between the walls and windows of the house is prevented or suppressed.

The air in the room is also sucked by the operation of the fan 8 and returns to the room again through the filters 22 and 23 via the damper 9B (solid arrow 13 in the figure). By such a circulation, when the indoor air passes through the filters 22 and 23, the smell of food or tobacco contained in the indoor air is removed by each filter, so that the cleanliness of the indoor air increases. .

As described above, in the positive pressure air supply / air cleaning mode, the outside air is introduced into the room by the fan 8 through the filters 3, 22, and 23, so that the room has a positive pressure. It is possible to effectively prevent harmful substances such as pollen and dioxin from entering the room. In addition, the fan 8 filters the indoor air into the filters 21 and 2.
Since the air is circulated through 2 and 23, it is possible to purify the indoor air even when the indoor air is contaminated by smoke of cigarettes or the like.

Further, since the inside of the room is at a positive pressure by the fan 8, it is possible to prevent outside air from entering the room for a short time when opening and closing the door.

[0026]

As described above in detail, according to the present invention, the outside air suction means for sucking the outside air, the inside air suction means for sucking the room air, the moisture adsorption area, the preheating area and the humidification area are arranged at fixed positions. The moisture adsorption element is rotated at a predetermined speed so as to sequentially transition from the moisture adsorption area to the humidification area and the preheating area, a filter, the air path of the outside air sucked by the outside air suction means, and suction by the inside air suction means. Air path switching means for switching the air path of the room air that has been provided, and the air path switching means causes the room air sucked by the inside air suction means to return to the room through the filter, and to the outside air suction means. Positive air supply / air cleaning mode for supplying the outside air sucked into the room via a filter, and discharging the outside air sucked by the outside air suction means to the outside after passing through the moisture adsorption area of the moisture adsorption element. And shy The indoor air that is drawn by the pull stage,
After passing through the preheating area of the moisture adsorption element and then heating and passing through the humidification area, the humidification mode to return to the room is switched and executed, so in the positive pressure air supply / air cleaning mode, the filter is By supplying the outside air through the room, the inside of the room is made to have a positive pressure, and the inconvenience of harmful substances, such as pollen, entering the room through a gap in a house or the like can be prevented or suppressed. And since indoor air is also circulated through a filter, further purification of indoor air is also achieved.

In the humidification mode, it is possible to absorb the moisture in the outside air adsorbed in the moisture adsorption area of the moisture adsorption element into the heated room air passed through the humidification area and return it to the room for humidification. become able to. In particular, in this case, there is no need to separately supply water like a normal humidifier,
It is extremely effective in dry seasons such as winter.
