Description

  The present invention relates to a wind direction control mechanism for an air outlet suitable for use in an air outlet provided on an indoor ceiling in a residential ventilation system, and a ductless ventilation system using the same.

  In order to prevent the occurrence of so-called sick house syndrome due to volatile organic compounds such as formaldehyde, acetaldehyde, toluene and xylene generated from building materials and their adhesives or termite inhibitors in recent years, it is legally newly built detached houses. Also for apartment houses, it is required to ventilate 0.5 times / hr continuously for 24 hours.

  By the way, as a conventional ventilation system in a house, for example, as shown in FIG. A fan 4 is provided, and the discharge side of the exhaust fan 4 is connected to the exhaust port 4b through an exhaust duct 4a provided in the ceiling 5 and between the living room 1 and the sanitary space 3, and between the sanitary space 3 and the corridor 6 In addition, there is known one in which a ventilation portion 7 is provided between the hallway 6 and the living room 2. Incidentally, the ventilation portion 7 is a gap at the lower portion of the door provided between the two chambers, a door gallery or the like.

  This is called a third type ventilation system, and the exhaust fan 4 forcibly exhausts the air in the sanitary space 3 from the exhaust port 4b to the outside through the exhaust duct 4a provided in the ceiling 5. As a result, outdoor air naturally flows into the living rooms 1 and 2 from the air supply openings 1a and 2a, and further flows from the ventilation portion 7 to the corridor 6 and the sanitary space 3, so that the entire air in the dwelling unit is ventilated. It is a thing.

  In the conventional ventilation system, the exhaust fan 4 and the exhaust duct 4a may be installed on the ceiling of the sanitary space 3 and in the ceiling 5; however, although there is an advantage that the structure is simple and economical, As described above, if ventilation is performed 0.5 times / hr continuously for 24 hours, a comfortable air-conditioning environment cannot be maintained in the living rooms 1, 2, etc. Since it was continuously introduced into the dwelling unit, there was a problem that it could not endure the residence at all.

As a conventional ventilation system for solving such problems, a first type ventilation system shown in FIG. 15 is known.
In this ventilation system, a heat exchange unit 8 having an exhaust fan built in the ceiling 5 is provided, and the air in the sanitary space 3 is sent to the heat exchange unit 8 through the exhaust duct 3a provided in the ceiling 5 and then the exhaust duct. 4a and the exhaust port 4b were exhausted, and along with this, the outside air flowing in from the air supply port 9 was installed in the ceiling 5 after exchanging heat with the indoor air to be exhausted in the heat exchange unit 8. Through the air supply duct 9a, the air is supplied into the room from an air outlet 9b provided in the ceiling of the living rooms 1 and 2.

  According to the above conventional ventilation system, in the heat exchange unit 8, after the outside air taken into the dwelling unit through the air supply port 9 is heat-exchanged with the air exhausted from the room, the air is supplied into the living rooms 1 and 2. Therefore, compared with what was shown in FIG. 14, it can supply outside air to the living room 1, 2 grade | etc., After approaching indoor temperature more.

  However, even in the ventilation system described above, the air flow path in the heat exchange unit 8 is narrow, and thus the air flow rate is increased. On the other hand, it is difficult to ensure a large heat exchange area. It is difficult to reduce the temperature difference between the outside air and the exhaust gas, and there is a problem that the energy cost required for air conditioning increases in order to maintain the desired air conditioning environment.

  In addition, since it is necessary to provide the air supply duct 9a, the exhaust ducts 3a, 4a, etc. in the ceiling 5, the ceiling 5 becomes narrow and obstructs maintenance and inspection, and the construction cost increases. There was also a point.

Therefore, the present inventors previously proposed a ductless ventilation system for a detached house as seen in Patent Document 1 below.
This ductless ventilation system uses the inside of the ceiling as an air supply duct. A circulation type air supply fan is provided in the ceiling, and an outside air intake duct and a corridor are provided on the suction side of the circulation type air supply fan. A recirculation duct for exhausting air is connected, and the discharge side of the circulating air supply fan is opened in the ceiling, and an air outlet for introducing the air in the ceiling into the room is provided in the living room. An exhaust fan is provided on the ceiling to exhaust the internal air directly to the outside.

  In the ductless ventilation system, the circulation type air supply fan allows the outside air of 0.5 times / hr from the outside air intake duct and the corridor of 0.5 times / hr to be exhausted through the circulation duct. The air is mixed and sent into the ceiling, which becomes the air supply duct. Then, the air in the ceiling is supplied to the living room from the air outlet and flows to the sanitary space and the hallway through the ventilation portion. In parallel with this, the air in the sanitary space of 0.5 times / hr corresponding to the intake of outside air is exhausted from the exhaust fan to the outside.

  As a result, according to the above ductless ventilation system, ventilation can be performed at an amount of 1.0 times / hr in the dwelling unit. In addition to being able to secure the amount, the indoor air and the outside air from the reflux duct are mixed in a wide space in the ceiling, so that there is an advantage that the heat shock due to the temperature difference between the inside and outside can be greatly relieved. . In addition, since the number of ducts to be installed in the ceiling can be greatly reduced, the economy is excellent.

  By the way, in the ductless ventilation system, since air in the ceiling serving as the air supply duct is supplied from the air outlet provided in the ceiling of the living room, a draft (air flow) directed downward is provided in the room. There was a drawback that it would occur. In particular, in the above room, since the air outlet is provided at the corner of the room because the lighting is provided in the center of the room, the air cooled by the draft through the wall, the window glass and the like is 24. There was a problem in that the air was continuously supplied over time, causing discomfort to the residents.

In addition, since the air inside the ceiling, which is the air supply duct, becomes positive pressure due to the air supplied from the circulation type air supply fan, some air is transmitted from the inside of the ceiling to the inside of the wall and from appliances such as outlets and terminal connectors. Although it may be ejected and the flow rate itself is very small, depending on the arrangement of the chair, the bed, etc., there is a risk that the resident may be uncomfortable.
