Description

  The present invention relates to a blower that blows out air sucked from a suction port from a blower outlet and an opening / closing mechanism for closing an opening provided in a housing so that the opening can be opened and closed by a turning operation of a door.

  Conventionally, many air conditioners equipped with a plurality of fans in a casing have been put into practical use. As literatures in which this type of air conditioner is disclosed, JP 2012-154494 A (Patent Literature 1) and JP 2012-37087 A (Patent Literature 2) are cited.

  The air conditioner disclosed in Patent Literature 1 includes a plurality of fans housed in a plurality of fan chambers provided on the front side inside the housing and a single heat provided on the rear side inside the housing. And a plurality of heat exchangers housed in the exchanger housing chamber. A blower outlet communicating with each of the plurality of fan chambers is provided on the front side of the casing, and a suction port communicating with the heat exchanger housing chamber is provided on the rear side of the casing. Each of the plurality of fan chambers communicates with the heat exchange storage chamber.

  The air sucked from the suction port is heat-exchanged by the heat exchanger. The heat-exchanged air is divided into a plurality of parts, each of which is blown out from a different outlet through a plurality of fan chambers.

  In the air conditioner disclosed in Patent Document 2, a suction port is formed in the upper part of the housing, a blow-out port is formed in the lower part of the front surface of the housing, and a plurality of downstream ports are formed on the downstream side of the suction port in the housing.

  In the air conditioner disclosed in Patent Document 1, for example, when the output of one fan is larger than that of other fans, the air suction force of the one fan is greater than the suction force of the other fan. Also grows.

  Since the plurality of fan chambers communicate with each other through the heat exchanger housing chamber, when the suction force of one fan becomes considerably large, air is sucked from the outlets of the other fan chambers. The sucked air enters the one fan chamber through the heat exchanger housing chamber. For this reason, it becomes difficult to blow out air of a desired air volume from each outlet. Further, since a filter for collecting dust contained in the air is not disposed at the air outlet, the dust enters the housing, and these are blown out from the one fan chamber and diffused into the room. .

  In the air conditioner disclosed in Patent Document 2, the plurality of wind direction adjusting blade portions are connected to a stepping motor. When the motor is driven in accordance with the number of command steps from the control device, the wind direction adjusting blade part swings.

  In general, in an air conditioner equipped with a wind direction adjusting blade part, after moving the wind direction adjusting blade part to the initial swing position considered to be optimal at the start of operation, the air direction adjusting blade part is blown while blowing air. Rock. When the stepping motor as described above is provided, it is swung in the swinging direction until the wind direction blade part stops moving, and the stepping motor is driven based on a predetermined number of steps from the position where the wind direction adjusting blade part stops moving. Let As a result, the wind direction adjusting blade portion moves to the initial swing position.

  However, since it takes time to move the wind direction adjusting blade portion to a position where it does not move, it takes a considerable amount of time to adjust the initial position of swing. In addition, when the user manually moves the wind direction adjusting blade part while the operation is stopped, the wind direction adjusting blade part may be adjusted to a position deviated from the initial position that seems to be optimal due to step-out. .

  In general, a filter for collecting dust and the like contained in the air is disposed at the air inlet of the air conditioner, and air from which dust and the like have been removed is blown out from the air outlet. When the filter is used for a long time, dust accumulates on the filter, so that it is necessary to clean or replace the filter.

Here, when it is set as the structure which fastens the side surface of a housing | casing to the main-body part of a housing | casing using a fastening member etc., attachment and removal of a side surface require time and effort, and become inconvenient.

  On the other hand, in the case of using a hinge mechanism constituted by a side member of the housing and the main body and a separate member, the number of parts increases, thereby increasing the cost. Further, a hinge mechanism having a cylindrical portion and a shaft portion inserted into the cylindrical portion is composed of a portion molded integrally with the side surface of the housing and a portion molded integrally with the main body portion of the housing. In some cases, the shaft portion is inserted into the tubular portion with the side surface inclined to some extent. For this reason, it takes time and effort to adjust the inclination. Moreover, since a considerable load is applied to the shaft portion during insertion, the shaft portion is easily damaged.

  The case 61 is composed of an upper case 62 and a lower case 63. The upper case 62 has accommodating portions 62a and 62b. In the accommodating space between the accommodating part 62a and the lower case 63, a substrate 69a for fixing the discharge electrodes 65a and 65b and the induction electrode 65e and the high voltage generating circuit part 66 are accommodated. A substrate 69b that fixes the discharge electrodes 65c and 65d is accommodated in the accommodation space between the accommodation portion 62b and the lower case 63.

  The ventilation space is formed by the inner peripheral surface of the case 61 with the communication portion 68 connecting the accommodation space between the accommodation portion 62a and the lower case 63 and the accommodation space between the accommodation portion 62b and the lower case 63 interposed therebetween. 64a and 64b are formed.

  The discharge electrode 65a and the discharge electrode 65c are accommodated in the case 61 so that the tips thereof are located in the blower space 64a. Further, the discharge electrode 65a and the discharge electrode 65c are arranged to face each other so that the central axes of the electrodes are located on the same straight line.

  The discharge electrode 65b and the discharge electrode 65d are accommodated in the case 61 so that the tips thereof are located in the air blowing space 64b. Further, the discharge electrode 65b and the discharge electrode 65d are arranged to face each other so that the central axes of the electrodes are located on the same straight line.

  These discharge electrodes 65a to 65d have a needle shape with a sharpened tip. The discharge electrodes 65a to 65d are provided in the same plane. The discharge electrodes 65a to 65d are arranged so that the central axes of the electrodes are parallel to each other.

  The discharge electrode 65a and the discharge electrode 65b are separated from each other in a direction orthogonal to the central axis of the electrode. The discharge electrode 65c and the discharge electrode 65d are arranged apart from each other in a direction orthogonal to the central axis of the electrode.

  The induction electrode 65e is disposed between the discharge electrode 65a and the discharge electrode 65b. The induction electrode 65e is provided at a position that is the same distance from the discharge electrode 65a and the discharge electrode 65b, and is provided at a position that is the same distance from the discharge electrode 65c and the discharge electrode 65d.

  The discharge electrode 65a and the discharge electrode 65c generate ions with different polarities, and the discharge electrode 65b and the discharge electrode 65d generate ions with different polarities. The discharge electrode 65a and the discharge electrode 65b generate ions having different polarities, and the discharge electrode 65c and the discharge electrode 65d generate ions having different polarities.

  When a positive or negative high voltage is applied to the discharge electrode 65a and a negative or positive high voltage is applied to the discharge electrode 65b, a corona discharge is generated between the discharge electrode and the induction electrode 65e, and positive ions and Negative ions are generated. Similarly, when a negative or positive high voltage is applied to the discharge electrode 65c and a positive or negative high voltage is applied to the discharge electrode 65d, a corona discharge is generated between the discharge electrode and the induction electrode 65e, Negative ions and positive ions are generated.

  Each of the discharge electrodes 65a to 65d is electrically connected to the high voltage generation circuit unit 66, and the high voltage generated by the high voltage generation circuit unit 66 is applied to the discharge electrodes 65a to 65d.

The positive ions are mainly composed of H ⁺ (H ₂ O) _n and the negative ions are mainly composed of O ₂ ⁻ (H ₂ O) m. n and m are integers. When positive ions and negative ions aggregate on the surface of airborne bacteria and odor components, a hydrogen peroxide solution H ₂ O ₂ or a hydroxyl radical [.OH], which is an active species, is generated by a chemical reaction. Since hydrogen peroxide and hydroxyl radicals have extremely strong activity, suspended bacteria and odor components are destroyed.

For example, the partition wall 45 is inserted and attached to the inside of the housing 10 from the opening 111 of the main body 110. The partition wall 45 includes a bottom 45a, a peripheral wall 45c, and a protrusion 46.

  The bottom portion 45a of the partition wall 45 is disposed so as to be in contact with the side surfaces of the blower side ducts 54A and 54B provided with the intake ports 7A and 7B. The bottom 45a has openings 45b1 and 45b2. The openings 45b1 and 45b1 are arranged with a distance from each other in the vertical direction.

  The peripheral wall portion 45c of the partition wall 45 is provided so as to stand from the peripheral edge of the bottom portion 45a toward the suction port 11 side. The protrusion part 46 is comprised by the plate-shaped protrusion piece, for example. The protruding portion 46 is provided at the approximate center of the bottom portion 45 a of the partition wall 45.

  The protruding portion 46 is provided so as to rise from the bottom 45a located between the opening 45b1 and the opening 45b2 toward the suction port 11 side. The protrusion 46 extends in the front-rear direction (Y-axis direction) and is provided so as to bridge the inner surface of the housing 10 in the front-rear direction. The tip of the protrusion 46 located on the suction port 11 side is fitted in a recess 43a of the filter unit 40 described later.

  As shown in FIGS. 9 and 10, the filter unit 40 includes a first filter portion 41A, a second filter portion 41B, and a holding frame 42 for holding them. The first filter portion 41A and the second filter portion 41B function as filter portions that capture dust when air passes. The first filter part 41A and the second filter part 41B are arranged apart from each other in the vertical direction.

  The holding frame 42 has a frame shape and has two windows arranged in the vertical direction. A first filter portion 41A and a second filter portion 41B are disposed in each of these two window portions. The holding frame 42 is provided with a rib 43 that protrudes toward the partition wall 45 at a portion located between the first filter portion 41A and the second filter portion 41B. The rib 43 has a recess 43a.

  The holding frame 42 has a protruding portion 49 that protrudes toward the suction port 11 on the side opposite to the side on which the rib 43 is provided. The protruding portion 49 is provided so as to reach the suction port 11. The protruding portion 49 is provided in the vicinity of the lower end side of the first filter portion 41A. The protruding portion 49 may be omitted.

  The filter unit 40 is detachably attached to the housing 10. The filter unit 40 is inserted and attached into the housing 10 through the opening 111 of the main body 110 after the partition wall 45 is attached. At this time, the tip of the protrusion 46 is fitted into the recess 43 a of the rib 43.

  After the filter unit 40 is attached, the opening 111 of the main body 110 is closed by the door 120. In this state, spaces defined by the inner wall portion of the housing 10 up to the filter unit 40, the inner peripheral surface of the holding frame 42, the peripheral wall portion 45c of the partition wall 45, and the blower side ducts 54A and 54B communicate with each other. The ventilation path R (refer FIG. 11) is comprised.

  FIG. 11 is a diagram schematically illustrating a blowing path of the blowing device illustrated in FIG. 9. With reference to FIG. 11, the ventilation path | route R is demonstrated.

  As shown in FIG. 11, the air blowing path R is provided inside the housing 10, and connects the first air passage R1 connecting the suction port 11 and the first air outlet 100A1, the air inlet 11 and the second air outlet 100B1. It connects to each of the suction inlet 11, the 1st blower outlet 100A1, and the 2nd blower outlet 100B1 so that 2nd wind path R2 to connect may be formed. The air blowing path R is defined by a duct 4 constituted by an upstream duct 4C and downstream ducts 4A and 4B, which will be described later.

  The first air path R <b> 1 and the second air path R <b> 2 are defined by a common upstream duct 4 </ b> C in the upstream portion of the air blowing path R connected to the suction port 11. The upstream duct 4 </ b> C is configured by an inner wall portion of the main body portion 110 from the suction port 11 to the first filter portion 41 </ b> A and the second filter portion 41 </ b> B and a part of the inner peripheral surface of the holding frame 42.

  The first air path R1 and the second air path R2 are respectively defined by the downstream ducts 4A and 4B on the downstream side of the air blowing path R connected to the first air outlet 100A1 and the second air outlet 100B1.

  The protrusions 46 of the partition wall 45 included in the housing 10 and the recesses 43a of the ribs 43 provided on the holding frame 42 of the filter unit 40 are fitted to each other, thereby forming the fitting part 47, thereby forming the blowing path R. Is defined by a downstream duct 4A (one duct) and a downstream duct 4B (the other duct).

  By fitting the protruding portion 46 of the partition wall 45 into the recess 43a of the rib 43, the rib 43 is located on the downstream side of the air flow from the first filter portion 41A and the second filter portion 41B, and is surrounded by the peripheral wall portion 45c of the partition wall 45. A partition wall 48 is formed that separates the space between the upper side and the lower side.

  Of the space surrounded by the peripheral wall 45c of the partition wall 45, the upper space separated by the partition wall 48 communicates with the blower side duct 54A independent of the blower side duct 54B. In addition, the space on the lower side separated by the partition wall portion 48 among the space surrounded by the peripheral wall portion 45c of the partition wall 45 communicates with the blower side duct 54B independent of the blower side duct 54A.

  In this manner, the partition wall portion 48 is formed by the protruding portion 46 of the partition wall 45 that is a part of the housing 10 and the rib 43 that is a part of the holding frame 42, thereby the first filter portion 41 </ b> A and the second filter. The first air path R1 and the second air path R2 are completely separated from the air blowing path R on the air blowing downstream side of the portion 41B.

  Further, when the projecting portion 49 provided on the holding frame 42 reaches the suction port 11, the air blowing path R defined by the upstream duct 4C is also separated into the first air path R1 and the second air path R2. .

  FIG. 12 is a diagram illustrating an example of air flow in the air blowing path illustrated in FIG. 11. With reference to FIG. 12, the flow of the air in the ventilation path | route R is demonstrated. In addition, in FIG. 12, the flow of the air when the rotation speed of the 1st air blower 51A is made higher than the rotation speed of the 2nd air blower 51B is shown.

  As shown in FIG. 12, when the rotation speed of the first blower 51A is made higher than the rotation speed of the second blower 51B, the suction force of the first blower 51A is larger than the suction force of the second blower 51B.

  In the present embodiment, the protrusions 46 of the partition wall 45 and the recesses 43a of the ribs 43 provided on the holding frame 42 of the filter unit 40 are fitted together, whereby the first filter part 41A and the second filter part 41B are The downstream side including air is completely separated.

  For this reason, it is prevented that 1st air path R1 and 2nd air path R2 connect in the ventilation downstream of 1st filter part 41A and 2nd filter part 41B. The air blowing upstream side of the first filter part 41 </ b> A and the second filter part 41 </ b> B is opened to the atmosphere via the suction port 11. Thereby, even when the suction force of the first blower 51A becomes considerably larger than the suction force of the second blower 51B, the air on the second air path R2 side is prevented from being sucked into the first air path R1 side. As a result, it is possible to prevent air from being sucked in from the second outlet 100B1 side.

  Therefore, when the rotation speed of the first blower 51A is made higher than the rotation speed of the second blower 51B, the air flow that passes through the first air passage R1 and is blown from the first outlet 100A1 stably. The air volume can be made larger than the air volume of the air flow that passes through the second air path R2 and is blown out from the second air outlet 100B1.

  Moreover, when making the rotation speed of the 2nd air blower 51B higher than the rotation speed of the 1st air blower 51A, it can prevent that the air by the side of 1st air path R1 is inhaled by the 2nd air path R2 side, and is stable. Thus, the air volume of the air flow blown from the second air outlet 100B1 through the second air passage R2 is larger than the air volume of the air flow blown from the first air outlet 100A1 through the first air passage R1. Can do a lot.

  Thus, in the blower device 1 according to the present embodiment, it is possible to prevent the backflow of air from the air outlets and to blow out air of a desired air volume from each air outlet.

  Further, the holding frame 42 is provided with a projecting portion 49 projecting toward the suction port 11 so as to reach the suction port 11, and the upstream duct 4C is completely connected to the first air path R1 and the second air path R2. By separating into two, the movement of air from the first air path R1 to the second air path R2 and the movement of air from the second air path R2 to the first air path R1 can be more reliably prevented. Thereby, while being able to prevent the backflow of the air from a blower outlet more reliably, the air of desired air volume can be reliably blown out from each blower outlet.

  FIG. 13 is a diagram showing the blower shown in FIG. 1 and the center lines of the first air flow and the second air flow blown out from the blower. With reference to FIG. 13, a mode that the airflow blown out from the air blower shown in FIG. 1 is spread | diffused indoors is shown.

  As shown in FIG. 13, the air blown out from the first outlet 100A1 passes through the first wind direction adjusting unit 20A in the wind direction adjusting unit 3A, thereby drawing an arc that is convex with respect to the blowing direction. It spreads radially in the vertical direction. In this manner, the fan-shaped first air flow 5 is blown out through the first wind direction adjusting unit 20A.

  The first air flow 5 has a predetermined thickness with respect to the horizontal direction (perpendicular to the paper surface), and has a band shape when viewed from the front. By constricting the air into such a shape, the first air flow 5 can be blown far away along a predetermined direction.

  The first air flow 5 has a center line 5a. Here, the center line 5a refers to a line connecting the fastest wind speed portions along the blowing direction in each section when the first air flow 5 is divided and divided in a substantially arc shape along the blowing direction. . There is a tendency that the wind speed of the air passing between the front end portion of the first air direction adjusting plate 21 and the front end portion of the second air direction adjusting plate 22 is increased.

  The air blown out from the second outlet 100B1 passes through the second wind direction adjusting unit 20B in the wind direction adjusting unit 3B, and spreads radially in the left-right direction so as to draw a circular arc that is convex with respect to the blowing direction. . In this way, the fan-shaped second air flow 6 is blown out through the second wind direction adjusting portion 20B.

  The second air flow 6 has a predetermined thickness with respect to the vertical direction, and has a belt-like shape when viewed from the front. By constricting the air into such a shape, the second air flow 6 can be blown far away along a predetermined direction.

  The second air flow 6 has a center line 6a. Here, the center line 6a refers to a line connecting the sections with the highest wind speed along the blowing direction in each section when the second air flow 6 is divided and divided in a substantially arc shape along the blowing direction. . There is a tendency that the wind speed of the air passing between the front end portion of the first air direction adjusting plate 21 and the front end portion of the second air direction adjusting plate 22 is increased.

  The blower device 1 according to the present embodiment is installed at the center on the side wall 600c side of the room 600. Moreover, the air blower 1 is installed on the floor surface 600b. The blower 1 has the first air flow 5 and the second air flow toward the other side wall 600d located on the side opposite to the installed side wall 600c side via the first wind direction adjusting unit 20A and the second wind direction adjusting unit 20B. Air stream 6 is blown out.

  The first wind direction adjusting unit 20A and the second wind direction are arranged so that the center line 5a of the first air flow 5 and the center line 6a of the second air flow 6 intersect in front of the blower 1 before reaching the other side wall 600d. An adjustment unit 20B is configured. At this time, the elevation angle of the center line 5a is smaller than the elevation angle of the center line 6a. Thereby, the ventilation range of the 1st airflow 5 and the ventilation range of the 2nd airflow 6 can be overlapped in a wider area.

  The first air flow 5 blown out through the first wind direction adjusting portion 20A located above moves toward the other side wall 600d while spreading radially in the vertical direction. The second air flow 6 blown out through the second wind direction adjusting portion 20B located below moves toward the other side wall 600d while spreading radially in the left-right direction.

  At this time, the first air flow 5 impinges on the second air flow 6 and moves toward the side wall 600d while diffusing the second air flow 6 toward the floor surface 600b. Further, the second air flow 6 travels toward the side wall 600d while colliding with the first air flow 5 to diffuse the first air flow 5 in the left-right direction.

  By using such a blowing method, air that has been squeezed so as to spread radially in the up-down direction and the left-right direction by the first wind direction adjusting unit 20A and the second wind direction adjusting unit 20B is caused to directly collide with the room. Can be diffused efficiently.

  In the present embodiment, the case where the center line 5a of the first air flow 5 and the center line 6a of the second air flow 6 intersect in the room has been described as an example. However, the present invention is not limited to this. As long as the blowing range of the first air flow 5 and the blowing range of the second air flow 6 can overlap, the elevation angle and direction of the center line 5a and the center line 6a can be appropriately selected.

  For example, the first wind direction adjusting unit 20A and the second wind direction adjusting unit 20B may be configured such that the elevation angle of the center line 5a is larger than the elevation angle of the center line 6a. In such a case, the center line 5a and the center line 6b do not intersect in the room, but a part of the blowing range of the first air flow 5 and a part of the blowing range of the second air flow 6 overlap. As described above, the first air flow 5 and the second air flow 6 can be diffused in the horizontal direction and the vertical direction. As a result, the air blown out from each outlet can be efficiently diffused into the room.

  Further, the first wind direction adjusting unit 20A and the second wind direction adjusting unit 20B may be configured such that the center line 5a and the center line 6a are in a twisted position. Even in such a case, a part of the air blowing range of the first air flow 5 and a part of the air blowing range of the second air flow 6 overlap, so that the first air flow 5 and the second air flow 6 are changed. It can be diffused in the horizontal and vertical directions. As a result, the air blown from each outlet can be efficiently diffused into the room.

  Furthermore, the first air direction adjusting unit 20A is swung in the left-right direction and the second air direction adjusting unit 20B is configured to be able to swing in the up-down direction, thereby changing the elevation angle of the center line 6a. The state where the center line 5a of the flow 5 intersects the center line 6a of the second air flow 6 and the state where the center line 5a of the first air flow 5 and the center line 6a of the second air flow 6 are in the torsion position. Can be produced as appropriate. Thereby, the air which blows off from each blower outlet can be diffused efficiently indoors over a wider area.

  In addition, a desired air volume can be blown out from the first outlet 100A1 and the second outlet 100B1 as described above. For this reason, when the air volume from the first air outlet 100A1 is increased, the air can be diffused further downward in the room, and when the air volume from the second air outlet 100B1 is increased, the air volume is increased. Air can be diffused upward.

  As shown in FIG. 17, the blower 1 </ b> C according to the present embodiment adjusts the initial swing position of the wind direction adjusting unit (wind direction adjusting unit) 3 when compared with the blower 1 according to the first embodiment. The second embodiment is different in that it further includes a photoelectric sensor 72 and a light shielding portion 77 that moves in conjunction with the swing of the wind direction adjusting unit 3. In addition, in FIG. 17, the blower outlet vicinity of the ventilation unit 2A side is illustrated in the ventilation unit 2A and the ventilation unit 2B which are contained in 1 C of ventilation apparatuses.

  Although the air blower 1C according to the present embodiment is not shown in FIG. 17, the first air blower 51A, the second air blower 51B, the air flow path R, which have the same configuration as the air blower 1 according to the first embodiment, Wind direction adjusting units 3A and 3B, a drive mechanism 71, and a control unit 70 are provided. The blower 1 </ b> C further includes a photoelectric sensor 72 and a light shielding unit 77.

  The ventilation path R is a part for blowing air sent out by the first blower 51A and the second blower 51B. The air direction adjusting units 3A and 3B are provided in the vicinity of the opening end (the opening end of the blowing ducts 100A and 100B) on the downstream side of the blowing path R. The wind direction adjusting units 3A and 3B are configured to be swingable so as to adjust the direction of the air blown from the blower path R and change the blowing direction.

  The drive mechanism 71, the photoelectric sensor 72, and the light shielding part 77 are provided in the air blowing unit 2A and the air blowing unit 2B, respectively. Each drive mechanism 71 swings the wind direction adjusting units 3A and 3B. For example, the drive mechanism 71 includes a drive motor 71a, a gear mechanism 75 attached to the rotation shaft of the drive motor 71a, and a gear mechanism 76 meshing with the gear mechanism 75. For example, a stepping motor can be used as the drive motor 71a. The wind direction adjusting units 3 </ b> A and 3 </ b> B are attached to the gear mechanism 76 so as to swing according to the rotation of the gear mechanism 76.

  When swinging the wind direction adjusting unit 3A, the drive motor 71a is driven, and the gear mechanism 75 is rotated in the DR3 direction via the rotation shaft of the drive motor 71a. As a result, the gear mechanism 76 rotates in the DR4 direction around the rotation axis C1. In response to the rotation of the gear mechanism 76, the wind direction adjusting unit 3A swings in the DR5 direction around the rotation axis C1.

  Specifically, when the gear mechanism 75 is rotated clockwise, the gear mechanism 75 is rotated counterclockwise. As a result, the wind direction adjustment unit 3A rotates counterclockwise. On the other hand, when the gear mechanism 75 is rotated counterclockwise, the gear mechanism 76 is rotated clockwise. As a result, the wind direction adjusting unit 3A rotates clockwise.

  The photoelectric sensor 72 includes a light emitting unit 73 and a light receiving unit 74. The photoelectric sensor 72 detects a light shielding state or a non-light shielding state depending on whether or not the detection light emitted from the light emitting unit 73 toward the light receiving unit 74 is shielded by the light shielding unit 77. In addition, it is preferable that the light emission part 73 and the light-receiving part 74 are provided so that it may rank with a rotation axis C1 direction.

  The light shielding portion 77 moves in conjunction with the swing of the wind direction adjusting unit 3A. The light shielding portion 77 is a plate-like portion provided in the gear mechanism 76 so as to be orthogonal to the direction of the rotation axis C1. The light shielding portion 77 rotates in the DR4 direction together with the gear mechanism 76.

  The light shielding portion 77 has an end portion 77a on one side in the rotation direction (DR4 direction), and an end portion 77b on the other side in the rotation direction. The rotation range of the gear mechanism 76 is configured to be larger than the range of the light shielding portion 77 from the one end portion 77a to the other end portion 77b.

  When at least a part of the light shielding part 77 is located on the optical path of the detection light emitted from the light emitting part 73, at least a part of the detection light is shielded. Thereby, the photoelectric sensor 72 detects a light shielding state. On the other hand, when the light shielding portion 77 is not positioned on the optical path of the detection light, the detection light is not shielded. Thereby, the photoelectric sensor 72 detects a non-light-shielding state.

  The control unit 70 receives the detection information from the photoelectric sensor 72 and controls the drive mechanism 71. The control unit 70 detects the position of the wind direction adjusting units 3A and 3B based on the detection information input from the photoelectric sensor 72, and controls the operation of the drive mechanism 71 based on the detected information.

  FIG. 19 is a diagram illustrating an example of a light shielding state, an example of a non-light shielding state, and other examples. 19A shows an example of a non-light-shielded state, FIG. 19B shows an example of a light-shielded state, and FIG. 19C shows another example of a non-light-shielded state. With reference to FIG. 19A, FIG. 19B, and FIG. 19C, the state of the photoelectric sensor 72 when the light shielding portion 77 rotates clockwise will be described.

  As shown in FIG. 19A, when one end 77a of the light shielding portion 77 is located behind the photoelectric sensor 72 in the clockwise rotation direction, the detection light L1 is not shielded. For this reason, the photoelectric sensor 72 detects a non-light-shielding state. From this state, when the light shielding portion 77 is rotated clockwise as indicated by the direction of the arrow A1, the end portion 77a reaches the optical path of the detection light L1. Thereby, a part of the detection light L1 is shielded, and the amount of light received by the light receiving unit 74 is reduced. Thereby, the photoelectric sensor 72 detects a light shielding state.

  When the light shielding portion 77 is further rotated clockwise, as shown in FIG. 19B, the light shielding portion 77 is positioned on the optical path of the detection light L1, and the detection light L1 is completely shielded. In this state, the photoelectric sensor 72 detects a light shielding state.

  When the light shielding portion 77 is further rotated clockwise, as shown in FIG. 19C, the other end 77b of the light shielding portion 77 is removed from the optical path of the detection light L1. Thereby, the detection light L1 is not shielded, and the amount of light received by the light receiving unit 74 is increased. Thereby, the photoelectric sensor 72 detects a non-light-shielding state.

  FIG. 20 is a diagram illustrating a flow for determining the initial swing position of the airflow direction adjusting unit of the blower illustrated in FIG. 17. With reference to FIG. 20, the flow for determining the initial swing position of the wind direction adjusting unit will be described.

  As shown in FIG. 20, first, in step (S1), the power is turned on, the control unit 70 can control the operation of various drive units, and the photoelectric sensor 72 is activated. Subsequently, in step (S2), the photoelectric sensor 72 determines whether the light emitted from the light emitting unit 73 is received by the light receiving unit 74, thereby detecting whether the light is in a light shielding state or a non-light shielding state.

  When it is detected in the step (S2) that the light is blocked, in the step (S3), the control unit 70 drives the drive mechanism 71 so that the wind direction adjusting unit 3A is moved in a predetermined direction around the rotation axis C1. Rock. Thereby, the light shielding part 77 is rotated in a predetermined direction in conjunction with the movement of the wind direction adjusting unit 3A. For example, the light shielding portion 77 is rotated clockwise around the rotation axis C1.

  Subsequently, in the step (S4), the photoelectric sensor 72 detects a non-light-shielding state when the light-shielding part 77 is removed from the optical path of the detection light L1. Based on the detection information input from the photoelectric sensor 72, the control unit 70 recognizes that the light shielding state has changed to the non-light shielding state, and detects the position of the wind direction adjusting unit 3A.

  On the other hand, when it is detected in the step (S2) that the light is not shielded, in the step (S5), the control unit 70 drives the drive mechanism 71 so that the wind direction adjusting unit 3A is moved around the rotation axis C1. Rock in the direction of. Thereby, the light shielding part 77 is rotated in a predetermined direction in conjunction with the movement of the wind direction adjusting unit 3A. For example, the light shielding portion 77 is rotated clockwise around the rotation axis C1.

  Subsequently, in step (S6), when the light shielding unit 77 reaches the optical path of the detection light L1, the photoelectric sensor 72 detects the light shielding state. Based on the detection information input from the photoelectric sensor 72, the control unit 70 recognizes that the non-light-shielding state has changed to the light-shielding state, and detects the position of the wind direction adjusting unit 3A.

  As described above, when the position of the wind direction adjusting unit 3A is detected in the step (S4) or the step (S6), the operation of the step (S7) is performed. In step (S7), the control unit 70 controls the operation of the drive mechanism 71 based on the detected position information of the wind direction adjusting unit 3A.

  Specifically, the control unit 70 controls the operation of the drive mechanism 71 so that a stepping motor as the drive motor 71a rotates a predetermined number of steps. Thereby, the control unit 70 moves the wind direction adjusting unit 3A to a predetermined swing start position. For example, when the blower 1C is installed at the approximate center of one of the side walls in the room, the initial swing position is preferably a central position within a swingable range of the air direction adjusting unit 3A.

  As described above, in the present embodiment, by providing the photoelectric sensor 72, the control unit 70 changes from the light shielding state to the non-light shielding state, or changes from the non-light shielding state to the light shielding state. Can recognize the position of the wind direction adjusting unit 3A. Similarly, the position of the wind direction adjusting unit 3B can be detected.

  For this reason, in this embodiment, the position is detected as compared with the case where the position of the wind direction adjusting units 3A and 3B is detected by moving the wind direction adjusting units 3A and 3B to a position where they cannot move. The movement range up to can be narrowed. As a result, it is possible to shorten the adjustment time of the initial swing position of the wind direction adjusting units 3A and 3B.

  Moreover, since the control part 70 can detect the exact position of wind direction adjustment unit 3A, 3B as mentioned above, when a user moves wind direction adjustment unit 3A, 3B manually during an operation stop, In addition, the position adjustment of the wind direction adjusting units 3A and 3B can be performed more reliably.

  The opening / closing mechanism 200 includes a first restriction mechanism 210, a second restriction mechanism 220 (see FIG. 27), and a third restriction mechanism 230. The first restriction mechanism 210 restricts the movement of the door 120 with respect to the main body 110 in a first direction (Z-axis direction) parallel to the virtual rotation axis C2. The second restriction mechanism 220 restricts the movement of the door 120 relative to the main body 110 in a second direction (Y-axis direction) orthogonal to the first direction and parallel to the opening surface 500 of the opening 111. The third restriction mechanism 230 restricts the movement of the door 120 relative to the main body 110 in a third direction (X-axis direction) orthogonal to the first direction and the second direction.

  As shown in FIGS. 23 to 25, the supported portion 300 includes a base portion 310, a first sandwiching portion 320, a bending portion 330, and a second sandwiching portion 340. The base part 310 has, for example, a staircase shape in which a flat part that faces the opening surface 500 of the opening part 111 has a step in the X-axis direction at the closed position.

  The first sandwiching part 320 is provided so as to stand in the X-axis direction from one side of the base part 310 in the Y-axis direction. The first sandwiching part 320 is constituted by a plate-like part 321 provided with a notch part 322. The notch 322 is notched from the one end 321a side to the other end 321b side at the substantially central portion of the plate-like portion 321.

  The bending portion 330 is provided so as to bend from the other end 321b side of the plate-like portion 321 so that the tip side faces the inner surface 400a of the main body portion 110 in the closed position. The curved portion 330 bends in the X-axis direction (X-axis negative direction) closer to the opening 111 as it goes in the Y-axis direction (Y-axis negative direction) away from the opening 111 at the closed position.

  The curved portion 330 is slidably provided on a curved surface 441 (see FIG. 26) of a rotation guide portion 440 (see FIG. 26) described later. The curved portion 330 is accommodated in a region surrounded by the curved surface 441 and the inner surface of the main body 110 at the closed position.

  The second sandwiching portion 340 includes an extension portion 341 that extends from the other end 321 b side of the plate-like portion 321 along the inner surface of the bending portion 330, and a plate-like portion 321. The plate-like portion 321 corresponds to one side portion of the second sandwiching portion 340 located on the side close to the opening 111 in the closed position. The extending portion 341 corresponds to the other side portion of the second sandwiching portion 340 located on the side farther from the opening 111 in the closed position.

  Between the extension part 341 and the plate-like part 321, there is provided a substantially triangular gap 342 whose interval becomes narrower toward the other end 321b side of the plate-like part 321. Thereby, the 2nd clamping part 340 can pinch the protrusion part 420 of the support part 400 mentioned later between the extension part 341 and the plate-shaped part 321 in a closed position.

  For example, two extending portions 341 are provided. The two extending portions 341 are provided so as to be aligned in the Z-axis direction. The two extending portions 341 are provided in the vicinity of both end portions in the Z-axis direction of the notch portion 322 provided in the plate-like portion 321.

  As shown in FIGS. 23, 24, and 26, the support part 400 includes a columnar protrusion part 410, a protrusion part 420, a step part 430, and a rotation guide part 440.

  The columnar protrusion 410 is provided on the one end 400c side of the opening end of the opening 111 in the Y-axis direction so as to protrude inside the main body 110 in the X-axis direction. The columnar protrusion 410 is provided so as to extend in the Z-axis direction. The columnar protrusion 410 has an upper surface 410a provided on one side in the Z-axis direction and a lower surface 410b provided on the other side.

  The protrusion 420 is provided so as to protrude inward of the main body 110 in the X-axis direction on one 400c side of the opening end of the opening 111 in the Y-axis direction. The protrusion 420 is provided so as to intersect the Y-axis direction. For example, two protrusions 420 are provided. The two protrusions 420 are provided on the upper surface 410a and the lower surface 410b of the columnar protrusion 410 so that portions close to the opening 111 side of the upper surface 410a and the lower surface 410b of the columnar protrusion 410 are exposed.

  The step portion 430 is formed by retreating the inner surface 400a of the main body 110 toward the outer surface 400b side on one 400c side of the opening end portion of the opening portion 111 in the Y-axis direction. The step portion 430 is provided so that one end side of the first sandwiching portion 320 abuts when the door 120 is located at the closed position.

  The rotation guide unit 440 has a curved surface 441. The curved surface 441 is located at a position facing the step portion 430 from the inner surface 400a of the main body portion 110 that is located farther from the opening portion 111 than the step portion 430 in the Y-axis direction when viewed from the inside of the main body portion 110. It curves toward the Y-axis direction (Y-axis positive direction) so as to approach the opening 111 as it travels in the X direction (X-axis positive direction) facing the inside of the main body 110 so as to reach.

  The curved surface 441 is provided along the circumferential direction about the virtual rotation axis C2. The curved surface 441 is provided such that the length in the radial direction from the virtual rotation axis C2 gradually increases from the position facing the step portion 430 toward the inner surface 400a side of the main body 110.

  The rotation guide unit 440 guides the rotation of the door 120 by having the curved surface 441 as described above. For example, two rotation guides 440 are provided. The two rotation guide portions 440 are provided so as to be aligned in the Z-axis direction. The two rotation guide portions 440 are provided such that the columnar protrusion portion 410 is positioned between the two rotation guide portions 440 when viewed from the Y-axis direction.

  FIGS. 27 to 29 are a perspective view and a partial cross-sectional top view of the opening / closing mechanism shown in FIG. 27 to 29 are a perspective view and a partial cross-sectional top view of a portion corresponding to a cross section taken along line AA shown in FIG.

  27A and 27B are a perspective view and a partial cross-sectional top view in the closed position of the opening / closing mechanism shown in FIG. FIG. 28A and FIG. 28B are a perspective view and a partial cross-sectional top view of the opening / closing mechanism shown in FIG. 29A and 29B are a perspective view and a partial cross-sectional view of the opening / closing mechanism shown in FIG. The opening / closing operation of the door 120 using the opening / closing mechanism 200 will be described with reference to FIGS. 27 (A), 27 (B) to 29 (A), 29 (B).

  As shown in FIGS. 27A and 27B, when the door 120 is in the closed position, the door 120 is moved by the first restriction mechanism 210, the second restriction mechanism 220, and the third restriction mechanism 230. It is regulated. On the other hand, the door 120 is rotatably supported around the virtual rotation axis C2.

  Specifically, the movement of the door 120 in the first direction is restricted by the first restriction mechanism 210 by the first pinching part 320 pinching the columnar protrusion 410 in the first direction.

  Further, the second sandwiching portion 340 sandwiches the projecting portion 420 in the second direction, whereby the movement of the door 120 in the second direction (Y-axis direction) is restricted by the second restricting mechanism 220. More specifically, the extending part 341 and the plate-like part 321 sandwich the protruding part 420.

  In this case, almost the entire area of the inner surface 341a of the extending portion 341 faces the outer surface 420a of the protruding portion 420 that is inclined with respect to the second direction. A part of the plate-like portion 321 on the other end 321 b side faces the tip side of the protruding portion 420.

  In addition, the one end 321 a side of the first sandwiching portion 320 abuts on the stepped portion 430, and the bending portion 330 positioned on the other end 321 b side of the first sandwiching portion 320 is in contact with the curved surface 441. The curved portion 330 is in contact with the curved surface 441 at a position P5 in the vicinity of the portion facing the step portion 430. As a result, the first sandwiching portion 320 and the bending portion 330 are sandwiched between the curved surface 441 and the step portion 430, and the movement of the door 120 in the third direction is restricted by the third restriction mechanism 230.

  As shown in FIG. 28A and FIG. 28B, when the door 120 is in the middle position from the closed position to the attach / detach position, the columnar protrusion 410 is sandwiched by the first sandwiching section 320. Maintained. Thereby, the state where the movement of the door 120 in the first direction by the first restriction mechanism 210 is restricted is maintained.

  The one end 321a side of the first sandwiching portion 320 is slightly separated from the step portion 430 in the positive X-axis direction as the door 120 rotates, but the curved portion 330 is maintained in contact with the position P5. . In this state, when the first sandwiching portion 320 moves in the negative X-axis direction, the one end 321a side abuts against the stepped portion 430, so that the movement of the door 120 in the second direction by the second restriction mechanism 220 is restricted. State is maintained.

  Further, as the door 120 rotates, the plate-like portion 321 rotates so as to follow the inclined direction of the protruding portion 420, and the extending portion 341 faces the outer surface of the inclined protruding portion 420 in the second direction. Rotate to reduce the area to play. In this state, since the extending part 341 and the outer surface side of the inclined projecting part 420 are opposed to each other, the state where the movement of the door 120 in the second direction is restricted by the second restricting mechanism 220 is maintained. The

  As shown in FIGS. 29A and 29B, when the door 120 is in the attachment / detachment position, the restriction of the movement of the door 120 relative to the main body 110 by the second restriction mechanism 220 is released and the first restriction is applied. When the movement of the door 120 is restricted by the mechanism 210 and the third restriction mechanism 230, the door 120 is moved away from the main body 110 in the second direction, so that the door 120 is removed from the main body 110. .

  Specifically, when the extending portion 341 is located on the tip side of the protruding portion 420 at the attachment / detachment position, the catch between the extending portion 341 and the protruding portion 420 is weakened. Thereby, the restriction | limiting of the movement to the 2nd direction of the door 120 by the 2nd control mechanism 220 is cancelled | released.

  On the other hand, the first sandwiching section 320 is movable in the second direction, although the columnar protrusion 410 is sandwiched in the first direction. In addition, the bending portion 330 is in contact with the curved surface 441 at the position P5, but is movable in the second direction.

  For this reason, the door 120 can be removed from the main body 110 by moving the door 120 generally in the second direction (Y-axis positive direction).

  In the state where the door 120 is removed from the main body 110, the door 120 is guided by the first restriction mechanism 210 and the third restriction mechanism 230, and the door 120 moves toward the main body 110 in the second direction. Thus, the door 120 is attached to the main body 110 when the door 120 reaches the attachment / detachment position.

  Specifically, the door 120 is moved in the second direction toward the main body 110 so that the first sandwiching section 320 sandwiches the columnar protrusion 410. At the same time as the first sandwiching portion 320 sandwiches the columnar protrusion 410, the bending portion 330 enters a space surrounded by the curved surface 441 and the inner surface of the main body 110. At this time, the extending portion 341 of the second sandwiching portion 340 gets over the tip of the protruding portion 420. Thereby, the door 120 reaches | attains an attachment / detachment position.

  In the present embodiment, the opening / closing mechanism 200 is constituted by the support part 400 provided integrally with the main body part 110 by injection molding or the like and the supported part 300 provided integrally with the door 120 by injection molding or the like. Since it is configured, the number of parts can be reduced as compared with the case where the opening / closing mechanism is configured by a separate member from the housing.

  In the present embodiment, the door 120 is guided by the first restricting mechanism and the third restricting mechanism 230 and moved so that the door 120 approaches the main body 110 in the second direction. The door 120 is rotatably attached to the main body 110 by reaching the attaching / detaching position. For this reason, the door 120 can be smoothly attached to the main body 110 as compared with the case of a hinge mechanism configuration in which the shaft portion is fitted into the cylindrical portion. As a result, convenience can be improved.

  In addition, compared to the case of a hinge mechanism configuration in which the shaft portion can be fitted into the cylindrical portion, the shaft portion is not subjected to a considerable load during installation, preventing damage and improving durability. It can also be made.
