本発明は室内の空調状態を確保しつつ、室内空
気の浄化を目的として、ひとつの送風機により室

This is what we provide.

持費が高くなる欠点があつた。 In recent years, with the spread of new construction materials, the airtightness of rooms has improved, making it difficult to replace indoor air with one-sided air supply or exhaust, and simultaneous intake and exhaust ventilation has become necessary. Conventionally, as a device to ventilate a room,
There is a ventilation fan, which is very effective for ventilation purposes. However, there was a drawback that it hindered the effectiveness of indoor heating and cooling. To improve this drawback, a ventilation fan with a built-in total heat exchanger has a complicated equipment configuration and requires two blowers, making it expensive and requiring a large ventilation opening in the wall of the room. Therefore, the disadvantage was that construction costs were high. Furthermore, conventional ventilation fans have the disadvantage of poor room temperature distribution because they do not have a function to circulate indoor air. On the other hand, an air purifier that purifies the air by circulating indoor air has been devised with a ventilation function.
Since it is simply a combination of a simultaneous intake/exhaust ventilation fan and an air purifier, the equipment configuration is complicated and large, similar to a ventilation fan with a built-in total heat exchanger, and it is expensive because it requires two or more blowers. The drawback was that maintenance costs were high.

To provide a blower device that purifies indoor air while ensuring indoor air conditioning. Embodiments of the present invention will be described below with reference to the drawings.

とを羽根車で同時に可能ならしめたものである。 Figure 1 shows an example using a double suction type centrifugal impeller, and Figure 2 is a sectional view taken along line A-A' in Figure 1 and line B-
A sectional view of B′ is shown. In Figures 1 and 2,
Reference numeral 1 designates a box body, which includes an indoor air intake port 3 having a filter 2, an indoor air discharge port 5 having a filter 4, and a ventilation tube 6 forming a flow path partitioned by a temperature/humidity exchange member or a heat conductive material. A ventilation port 7 is provided to connect the Inside the box body 1, a double suction type centrifugal impeller 9 driven by a motor 8 and a fan casing 12 forming two fan suction ports 10, 10' and a fan discharge passage 11 are housed. A room air suction passage 19 is formed between the port 10' and the room air intake port 3. Ventilation tube 6
A temperature/humidity exchange member or a heat conductive material is laminated in parallel at intervals to form a parallel passage, and an outside air supply passage 14 in which the fan suction port 10 and the outdoor air suction port 13 communicate with each other, and a fan discharge passage. An outdoor exhaust pipe 21 having an outdoor exhaust port 15 opening to the outside and an outdoor exhaust passage 17 communicating with an outdoor discharge port 16 disposed in the ventilation pipe 6 are configured in multiple layers. Reference numeral 18 indicates a wall having an opening through which the ventilation tube 6 passes. In such a configuration, the impeller 9 is driven by the motor 8.
When driven, indoor air a is sucked into the impeller 9 from the fan suction port 10' through the suction port 3 and the filter 2, and through the indoor air suction passage 19. At the same time, fresh outdoor air b is sucked into the impeller 9 through the fan suction port 10'. The outdoor air is sucked into the air supply passage 14 through the outdoor air suction port 13 , and into the impeller 9 through the fan suction port 10 . Indoor air a and outdoor air b drawn into the impeller 9 are mixed within the fan casing 12 and blown to the fan discharge passage 11 . The mixed air c in the fan discharge passage 11 is blown into the room from the discharge port 5 through the filter 4 and mixed at the same time as indoor air is circulated through the outdoor exhaust port 15 of the outdoor exhaust pipe 21 located in the fan discharge passage 11. A part of the air c is exhausted to the outside through the outdoor exhaust passage 20 and from the outdoor discharge port 16. At this time, the exhaust passage 1 in the ventilation tube 6
7 and the air supply passage 14 are temperature/humidity exchange members or
Since the parallel passages are partitioned with a heat conductive material, the outdoor air b sucked into the air supply passage 14 exchanges heat with the air c in the exhaust passage 17, and reaches the impeller in a state close to the temperature and humidity of the air c. It will be inhaled within 9 days. Therefore, the air blown into the room from the discharge port 5 is hardly affected by the fresh outside air taken in through the exhaust passage 14, and is circulated in the room at the same temperature and humidity as the indoor air a.
In other words, the present invention is a blower device that mixes indoor air and outdoor fresh air, which has been brought close to the indoor air condition through an air supply passage, inside a box, blows it indoors, and exhausts a part of it outdoors. This allows ventilation and indoor circulation to be performed at the same time using an impeller.

This is a cross-sectional view of B′, and the names of the same parts as in FIGS. 1 and 2 are indicated by the same symbols. In this embodiment, the ventilation pipe 6 is configured as a double pipe using a heat conductive material or a temperature/humidity exchange member to form an air supply passage 14 and an exhaust passage 17, and the air supply passage 14 is formed in an indoor air suction passage 19. The air supply port is located within the fan discharge passage 11, and the exhaust passage is located within the fan discharge passage 11.
5 is opened. In the above embodiment, since the air supply passage 14 and the exhaust passage 17 are constructed of simple double pipes, the cost is reduced and the flow resistance is the first.
Since the amount of air is greatly reduced compared to the embodiment shown in the figure, it is possible to increase the air supply/exhaust volume or to make the ventilation pipe 6 smaller. On the other hand, the total heat exchange rate of the air in the air supply passage 14 and the exhaust passage 17 in the ventilation tube 6 is low because the exchange area is much smaller than in the embodiment shown in FIG. It has been experimentally confirmed that by setting the suction air volume to be approximately twice or more than the outside air supply air volume, there is almost no influence on indoor air conditioning conditions due to the suction of outdoor air. In addition, the indoor air ventilation condition according to the present invention increases the oxygen concentration of the indoor air from 18% to 19.5% by increasing the air supply and exhaust air volume to 30 m 3 /H or more when burning a kerosene stove in a room equivalent to 6 tatami mats. By increasing the circulation air volume to 90m 3 /H or more, the room temperature distribution can be improved.
It can be improved from 14deg to 8deg.

や吸排の抵抗を増すこともない。 As described above, the blower device of the present invention includes a box body in which an intake port, a discharge port, and a ventilation port are arranged, and a ventilation tube having two or more flow paths, and includes a suction path for indoor air, a supply path for outdoor air, and a ventilation tube having two or more flow paths. , the exhaust passage to the outdoors and the discharge passage to the interior are connected to each other, and a single impeller has the functions of simultaneous supply/exhaust ventilation and indoor circulation, so that indoor air is always directed to the outdoors. In order to supply fresh air and circulate it inside the room, it must be maintained in a clean state, and the ventilation tube must form two channels separated by a temperature/humidity exchange member or a heat conductive material. Therefore, when inhaling outside air, the air can be inhaled in a state similar to indoor air using the exhausted indoor air, which prevents loss of energy for heating and cooling, which in turn saves operating costs for air conditioners and ventilation pipes. Since it has a cylindrical shape, the opening in the wall of the room can be circular with a diameter of about 100 mm, which has the excellent effect of making construction extremely easy.
In addition, since the ventilation tube is used to take air in and out of the room, the hole in the wall can be made smaller.Also, the ventilation tube has an outdoor suction port on the end and an outdoor discharge port on the side, so that the intake and exhaust air can be mixed. As a result, it will not be sucked in again and will not increase the resistance to suction and expulsion.
