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. 15, air supply ports 1a and 2a are provided on the outer walls of the living rooms 1 and 2 and exhausted to the ceiling of the sanitary space 3 such as a bathroom, washroom or toilet. 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. 16 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. 15, it can supply outside air to room 1, 2, etc., after approaching outside temperature more closely to indoor temperature.

  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.

In the room terminal fan 25, a motor 25a is disposed at the center of the opening 27, and a blade 25b is attached to an output shaft facing downward. Further, a cylindrical guide member 32 is erected on the mounting plate 31 so as to surround the room terminal fan 25, and a suction port 33 is formed at the top of the guide member 32 having a reduced diameter. . Thereby, the room terminal fan 25 feeds the air sucked from the suction port 33 downward.

  Under the room terminal fan 25, four moving members 35 to 38 are movably disposed on the upper surface of the fixed plate 28. Each of the moving members 35 to 38 is formed in a quadrangular pyramid shape in which each of the bottom plates 35 a to 38 a has the same dimensions as the fixed plate 28, and each of the moving members 35 to 38 has an axis line at the ridge line. It is formed in a shape divided in the direction. And each moving member 35-38 positions each top part below the center part of the room terminal fan 25, and positions the outer periphery of the baseplates 35a-38a in parallel with each outer edge 27a of the opening 27. It is provided so as to be able to advance and retreat toward the outer edge 27a. Thereby, the wall surface which inclines from the top part to each blower outlet 34a-34d of an outer peripheral side is formed in the side surface of each moving member 35-38.

  Each moving member 35 to 38 is formed hollow as shown in FIG. 7, and inner walls 35 b to 38 b are vertically provided in an intermediate portion in the moving direction. A cam mechanism (drive mechanism) 39 is provided in the internal space surrounded by the inner walls 35b to 38b.

  As shown in FIGS. 7 to 12, the cam mechanism 39 is inserted into the central portion of the fixed plate 28 and has a rotation shaft (drive rod) 40 provided with a knob 40 a for rotation operation at the lower end portion. The four cam plates 41a to 41d fixed at equal intervals in the axial direction of the rotating shaft 40 and the inner walls 35b to 38b of the moving members 35 to 38 are fixed and extended in the horizontal direction. Engagement plates 42a to 42d that contact the outer peripheral surfaces of the cam plates 41a to 41d, and one end portions are rotatably attached to the outer periphery of the rotation shaft 40, and the other end portions are attached to the inner walls 35c to 38c. By being fixed, the engaging plates 42a to 42d are constituted by springs (biasing members) 43a to 43d that urge the engaging plates 42a to 42d in a direction to contact the cam plates 41a to 41d.

In addition, the roller contact | abutted to the outer peripheral surface of each cam plate 41a-41d is rotatably integrated in the front-end | tip part of each engagement plate 42a-42d.
Furthermore, two guide grooves 45a to 45d extending in the moving direction are formed in parallel on the bottom plates 35a to 38a of the moving members 35 to 38, and the guide grooves 45a to 45d are formed on the other fixed plate 28. Pins 46a to 46d projecting inwardly project. Incidentally, the guide grooves 45 a to 45 d are formed to have a length dimension substantially equal to the distance between the outer peripheral edge of the bottom plates 35 a to 38 a and the outer edge side 27 a of the opening 27.

  Here, the shape of the cam curve of each of the cam plates 41a to 41d corresponding to the four moving members 35 to 38 will be described in detail with reference to FIGS. 8 to 12 show the rotation positions of the cam plates 41a to 41d and the moving members when the rotation angle of the rotation shaft 40 is 0 °, 90 °, 180 °, 270 °, and 360 °, respectively. The relationship between the positions 35 (each figure a), 36 (each figure b), 37 (each figure c), and 38 (each figure d) is shown.

  First, as shown in FIG. 8, when the rotation angle is 0 °, the outer peripheral surfaces of the cam plates 41a to 41d are positions where the moving members 35 to 38 are retracted from the outer edge 27a of the opening 27, that is, The air outlets 34a to 34d are formed to have a radius r 'where the air outlets 34a to 34d are opened.

  Next, as shown in FIG. 9, the outer peripheral surface of the cam plate 41 a is formed at a radius r that moves the moving member 35 to the outer edge 27 a of the opening 27 at a position where the rotation shaft 40 is rotated by 90 °. At the same time, the other cam plates 41 b to 41 d are formed at the radius r ′ where the moving members 36 to 38 are still retracted from the outer edge 27 a of the opening 27. Thereby, at the said rotation angle of 90 degrees, while the one blower outlet 34a is closed, the other blower outlets 34b-34d are hold | maintained.

  As shown in FIG. 10, the outer peripheral surfaces of the cam plates 41 a and 41 b move the moving members 35 and 36 to the outer edge 27 a of the opening 27 at the position where the rotation shaft 40 is rotated 180 °. The other cam plates 41 c and 41 d are formed at a radius r ′ where the moving members 37 and 38 are still retracted from the outer edge 27 a of the opening 27. As a result, at the rotation angle of 180 °, the two adjacent outlets 34a and 34b are closed and the other outlets 34c and 34d are kept open.

  Next, from this state, the outer peripheral surfaces of the three cam plates 41a to 41c are moved to the moving members 35 to 37 at a position where the rotating shaft 40 is rotated to 270 ° as shown in FIG. The other cam plate 41d is formed at a radius r ′ where the moving member 38 is retracted from the outer edge 27a of the opening 27 as it is. . Thus, at the rotation angle of 270 °, the three adjacent outlets 34a to 34c are closed and the other outlet 34d is kept open.

  Further, at the position where the rotation shaft 40 is further rotated to the position immediately before 360 ° as shown in FIG. 12, the outer peripheral surfaces of all the cam plates 41 a to 41 d open the moving members 35 to 38 with the openings 27. The radius r is made to move to the outer edge 27a. Thereby, in the said rotation angle, all the four outlets 34a-34d close.

  On the other hand, as shown in FIG. 3 and FIG. 4, support shafts 50 are provided upright at three positions among the four corners of the frame member 29 so as to penetrate the ceiling 11 a and extend upward from the suction port 33 of the guide member 32. In another place, a height adjustment shaft 51 having a height dimension equal to that of the support shaft 50 and having a screw portion 51a formed on the upper portion is erected rotatably. A plate-like air volume adjusting plate 52 is disposed above the suction port 33.

  In the air volume adjusting plate 52, the support shaft 50 is loosely inserted into holes formed at three positions in the four corners, and a nut 53 is fixed at the other one position. When the height adjustment shaft 51 is screwed onto the nut 53, the air volume adjustment plate 52 is provided so as to be movable in the vertical direction along the support shaft 50 by the rotation of the knob 51b of the height adjustment shaft 51. It has been.

In the airflow direction control mechanism of the air outlet and the ductless ventilation system using the same, the moving members 34 of the airflow direction control mechanism 26 are first arranged in accordance with the arrangement of the air supply openings 27 in the living room 11. Adjust the position.
For example, as shown in FIG. 5, when the opening 27 is formed in the vicinity of the window glass 47 and one of the four outlets 34 a to 34 d is located on the window glass 47 side. The air outlet 34a is closed.

  In this case, the knob 40a is operated from the indoor side to rotate the rotation shaft 40 to a rotation angle of 90 ° as shown in FIG. Thereby, the one moving member 35 corresponding by the cam board 41a is extruded to the blower outlet 34a side, and can close the blower outlet 34a located in the window glass 47 side.

  Further, as in the present embodiment shown in FIGS. 2 and 6, when the air outlet direction control mechanism 26 having the room terminal fan 25 is provided at the corner of each living room 11, the rotation axis 40 is further rotated by 90 ° to be positioned at a rotation angle of 180 ° as shown in FIG. 10. As a result, the moving member 36 corresponding to the cam plate 41b is also pushed out, so that it is already blocked by the moving member 35. The blower outlet 34b adjacent to the blower outlet 34a is also closed. As a result, the two outlets 35 and 36 located in the adjacent wall part 48a, 48b side can be closed.

In this way, the setting of the wind direction control mechanism 26 at the outlet is completed by closing the outlets 35 and 36 located on the side of the walls 48a and 48b.
Next, in this ductless ventilation system, the circulation type air supply fan 16 cleans the outside air in an amount of 0.5 times / hr sucked from the air inlet 17 through the outside air intake duct 18 and the filter 21. After that, the air in the corridor 13 having an amount of 0.5 times / hr exhausted through the reflux duct 19 is mixed and sent to the void space 14 in the ceiling serving as an air supply duct. Then, the air in the void space 14 is supplied from the blower outlet 35 into each room 11 by the room terminal fan 25.

  Then, the air in the living room 11 flows to the sanitary space 12 and the corridor 13 through the ventilation part 15, and in parallel with this, the air in the sanitary space 12 corresponding to the intake amount of outside air is 0.5 times / hr. Flows to the exhaust duct 23 piped to the void space 14 by the exhaust fan 22 and is exhausted from the exhaust port 24 to the outside.

  As a result, according to the above ductless ventilation system, the ventilation of 1.0 times / hr can be performed in the dwelling unit, so that a larger ventilation amount can be ensured than before, and the circulation duct 19 Since the sucked air in the corridor 13 and the outside air are mixed in the wide void space 14 in the ceiling, the heat shock due to the temperature difference between the inside and outside can be surely mitigated. In addition, since the number of ducts to be installed in the ceiling can be greatly reduced, the economy is excellent.

  In addition, since the room terminal fan 25 is provided for each air outlet direction control mechanism 26 installed in each room 11, the air in the void space 14 for supplying air is forcibly supplied to each room 11. Therefore, it is possible to reliably prevent the void space 14 from becoming an excessively positive pressure and a part of the supply air from being ejected from a wall outlet or the like.

  In addition to the operational effects of the ductless ventilation system described above, according to the airflow direction control mechanism 26 of the air outlet provided in the living room 11, the wall members 48a, 48b are moved by moving the moving members 35, 36 by the cam mechanism 39. Since the two outlets 34a and 34b located on the side can be closed, it is possible to prevent a downward draft along the walls 48a and 48b from occurring.

In addition, if the rotation shaft 40 of the cam mechanism 39 is further rotated, the other two outlets 34c and 34d can be sequentially closed.
In addition, a cylindrical guide member 32 is erected so as to surround the room terminal fan 25, and a suction port 33 is formed at the reduced diameter top portion of the guide member 32, and close to the suction port 33. Since the air volume adjusting plate 52 is provided, the height adjusting shaft 51 that supports the air volume adjusting plate 52 is rotated by the knob 51b to bring the air volume adjusting plate 52 into and out of contact with the suction port 33, for example. Even in the case where the opening 27 is arranged in the center of the living room 11, the amount of air supplied to the room can be easily adjusted without closing the air outlets 34a to 34d.

In addition, about the structure of the wind direction control mechanism of the blower outlet which concerns on this invention, it is possible to employ | adopt various structures besides the wind direction control mechanism 26 mentioned above.
For example, FIGS. 13 and 14 show another embodiment of the wind direction control mechanism, and components that are common to the wind direction control mechanism 26 including the cam mechanism 39 are given the same reference numerals. .

The wind direction control mechanism 60 differs from the wind direction control mechanism 26 in that the size of the fixing plate 28 that closes the central portion of the opening 27, the point that a sealing wall portion 61 is provided above the partition member 30, and further movement. It exists in the shape of the members 62-65.
That is, in this wind direction control mechanism 60, a rectangular tubular sealing wall 61 is provided at the upper end of the partition member 30 erected on the void space 14 side.

The sealing wall 61 is fixed to a flat fan mounting plate 31 for mounting the room terminal fan 25 at its upper end, and its lower end is positioned below the joining position with the partition member 30. It is formed as follows.
Further, the fixing plate 28 is formed in a square having a smaller outer dimension than those shown in FIGS. 3 and 4, and thereby each outer edge 27 a that defines the outer periphery of the fixing plate 28 and the opening 27. Between the two, four wide outlets 66a to 66d are formed.

On the fixed plate 28, moving members 62 to 65 are provided so as to be movable in the horizontal direction.
These moving members 62 to 65 include a bottom plate having a square shape as a whole, square cylindrical side walls 62a to 65a integrated on the outer peripheral edges of the bottom plates, and from the upper end portion to the top portion of the side walls 62a to 65a. It is formed in a shape comprising an inclined quadrangular pyramid-shaped top plate (inclined wall surface).

  And each moving member 62-65 is formed in the shape divided into four in the axial direction in the ridgeline of the said quadrangular pyramid, and the corner | angular part of a square cylinder. Further, the square formed by the bottom plate is formed smaller than the fixed plate 28. Further, the side plates 62 a to 65 a are formed in a height dimension such that the upper portion thereof faces the lower portion of the sealing wall portion 61.
