On the other hand, during the air conditioning operation of the air conditioner, as shown in FIGS. 2A and 2B, the front panel 3 moves a predetermined distance in the direction away from the main body 2 to open the front opening 2a. Is configured to do.

  As shown in FIG. 1, inside the main body 2, the heat exchanger 4 and the indoor air taken in through the filter 6 from the front opening 2 a and the upper opening 2 b are heat-exchanged by the heat exchanger 4 and blown out into the room. Fan 5 is provided. The filter 6 provided between the front opening 2a and the upper surface opening 2b and the heat exchanger 6 is provided to remove dust contained in room air taken in from the front opening 2a and the upper surface opening 2b. ing.

  In the air outlet 2c for blowing out the air heat-exchanged indoors in the air conditioner of the present embodiment, the air outlet 2c can be opened and closed and the air blowing direction can be changed in the vertical direction. A blade 10 is provided. Furthermore, left and right wind direction changing blades 9 that can change the air blowing direction to the left and right are provided inside the air outlet 2c.

  The up / down wind direction changing blade 10 includes a lower blade 11 that is an example of a first blade and an upper blade 12 that is an example of a second blade provided above the lower blade 11. The up-and-down air direction changing blade 10 is configured so that the lower blade 11 and the upper blade 12 cooperate to control the blowing direction of the air blown out from the air outlet 2c. The lower blade 11 is fixed to the lower blade drive shaft 13, and is provided to rotate about the lower blade drive shaft 13 by the rotation operation of the lower blade drive shaft 13. The upper blade 12 is configured to move toward and away from the lower blade 11 while being held substantially parallel to the lower blade 11 by a function of a link arm (main arm 14 and sub arm 15) described later. .

  The left and right wind direction changing blades 9 include, for example, a pair of blades positioned on the left side when viewed from the front of the indoor unit 1 and a pair of blades positioned on the right side. Each set of blades is composed of a plurality of (for example, five) blades. Each set of blades is connected to a separate drive source (for example, drive motor) 16 and is independently controlled by each drive source 16.

  When the air conditioner starts the air conditioning operation, the up / down air direction changing blade 10 opens and the air outlet 2c is opened. Thus, the fan 5 is driven in a state where the air outlet 2c is opened, and the indoor air is taken into the indoor unit 1 through the front opening 2a and the upper opening 2b. The taken indoor air passes through the filter 6, is heat-exchanged in the heat exchanger 4, and is sucked into the fan 5. The heat-exchanged air sucked into the fan 5 passes through the ventilation path 17 formed on the downstream side of the fan 5 and is blown out from the air outlet 2c.

  FIG. 3 is a perspective view showing an overall schematic configuration of the indoor unit 1 in the air conditioner of the present embodiment, and shows a human sensor unit by cutting a part of the indoor unit 1. In the indoor unit 1 according to the present embodiment, a human sensor unit 18 is provided on the front panel 3 as an example of an activity amount detection device that detects an activity amount of a person. Here, the “activity amount of a person” is a concept indicating the degree of movement of a person, such as “activity amount rest”, “activity amount large”, “activity amount”, “activity amount small”, etc. It is classified into multiple activity level. “Activity rest” refers to a case where there is almost no activity, such as when relaxing on a sofa. “Large amount of activity” refers to a case where the person is active frequently and widely in a wide area, such as when cleaning. “Activity amount” means a case where the user is active in a small area such as cooking. “Small amount of activity” refers to a case where there is some activity such as when eating. The human sensor unit 18 includes an infrared sensor that detects the presence or absence of a person by detecting infrared rays emitted from a human body, for example, and is based on a pulse signal corresponding to a change in the amount of infrared rays detected by the infrared sensor. Thus, the presence / absence of a person is determined. The specific configuration of the human sensor unit 18 is not particularly limited. For example, the human sensor unit disclosed in Japanese Patent Application Laid-Open No. 2008-215764 can be used.

  Next, the configuration of the up / down wind direction changing blade 10 will be described in more detail. FIG. 4 is a schematic diagram showing the configuration of the up / down airflow direction changing blade 10.

  As described above, the vertical wind direction changing blade 10 includes the lower blade 11 and the upper blade 12, and the lower blade 11 and the upper blade 12 are rotated and integrated in the vicinity of the outlet 2c. An airflow guide operation using single blades or an airflow guide operation using two blades is performed. In the up-and-down wind direction changing blade 10 in a single blade state, the lower blade 11 on the upstream side of the air blown out from the air outlet 2c is made of a resin material having a hollow inside, has rigidity, and has a heat insulating structure. It has a lightweight structure and a structure that prevents the occurrence of condensation. On the other hand, the upper blade 12 on the downstream side of the air blown out from the air outlet 2c is formed by processing one plate material, and has rigidity and weight reduction.

  The lower blade 11 and the upper blade 12 are connected by a link mechanism so as to maintain a substantially parallel state. In the present embodiment, the lower blade 11 and the upper blade 12 are connected to each other by a pair of link arms configured by a main arm 14 and a sub arm 15 so as to be separated from each other. Accordingly, the lower blade 11, the upper blade 12, the main arm 14, and the slave arm 15 constitute a four-bar linkage mechanism. The main arm 14 and the slave arm 15 are provided at positions separated by a predetermined distance in the flow direction of the airflow in the vertical airflow direction changing blade 10, and the turbulence of the airflow generated by the main arm 14 and the slave arm 15 is reduced as much as possible. It is configured as follows.

  The “substantially parallel state” means that the lower blade 11 and the upper blade 12 include not only a completely parallel state but also a substantially parallel state when viewed macroscopically. This is because, as the lower blade 11 and the upper blade 12, not only those having a linear shape or the same thickness but also those having a curved shape or a stepped portion can be used.

  The lower blade 11 is fixed to the lower blade drive shaft 13 and is configured to rotate by the lower blade drive shaft 13. The lower blade drive shaft 13 is disposed in the vicinity along the edge of the lower end 2d (see FIG. 4) on the wall side of the outlet 2c, and a lower blade drive source (not shown) provided in the main body 2. It is comprised so that rotation is possible. The lower blade drive source will be described later.

  The main arm 14 is configured to rotate by a predetermined angle by an upper blade drive shaft 19 disposed coaxially with the lower blade drive shaft 13. The upper blade drive shaft 19 is configured to rotate by an upper blade drive source (not shown) provided in the main body 2. The upper blade drive source will be described later.

  In the up-and-down wind direction changing blade 10 configured as described above, when the lower blade driving shaft 13 is rotated by the lower blade driving source, the lower blade is in a state in which the positional relationship between the lower blade 11 and the upper blade 12 is maintained. Is configured to rotate. Further, when the upper blade driving shaft 19 is rotated by the upper blade driving source, the main arm 14 is rotated, and the upper blade 12 performs a separating operation (approaching operation or separating operation) with respect to the lower blade 11.

  FIG. 5 is a view showing the rotation operation of the lower blade 11 and the upper blade 12 when the lower blade drive shaft 13 is rotated. FIG. 6 is a diagram showing the separation / contact operation between the lower blade 11 and the upper blade 12 when only the upper blade drive shaft 19 is rotated.

  As shown in FIG. 5, when the lower blade drive shaft 13 is rotated, the entire upper and lower wind direction changing blades 10 are kept in a state where the lower blade 11 and the upper blade 12 maintain the same distance (a state in which the interval is kept constant). Perform a pivoting motion. On the other hand, as shown in FIG. 6, when the upper blade drive shaft 19 is rotated, the upper blade 12 is maintained substantially parallel to the lower blade 11 while the position of the lower blade 11 is maintained. , Perform separate operation.

  FIG. 7 is an exploded perspective view showing the configuration of the up / down airflow direction changing blade 10 including the lower blade 11 and the upper blade 12. As shown in FIG. 7, gear units 20 and 21 serving as blade driving sources are provided on both sides of the lower blade 11. In FIG. 7, the first gear unit 20 disposed on the right side of the lower blade 11 is a lower blade drive source that rotates the lower blade drive shaft 13. On the other hand, the second gear unit 21 disposed on the left side of the lower blade 11 is an upper blade drive source that rotates the upper blade drive shaft 19. An air conditioner control device (not shown) controls the first and second gear units 20 and 21 to control the up-and-down airflow direction change blades 10, that is, the lower blade drive shaft 13 and the upper The lower blade 11 and the upper blade 12 are controlled via the blade drive shaft 19.

  In the present embodiment, the pair of the main arm 14 and the secondary arm 15 constituting the four-bar linkage mechanism is provided at three locations on both sides and the center of the up / down air direction changing blade 10. A through hole formed in one end portion of each main arm 14 is penetrated and engaged by the upper blade drive shaft 19 and is configured to be driven by a predetermined angle in accordance with the rotation of the upper blade drive shaft 19. Yes. The other end portion of each main arm 14 is pivotally supported at a predetermined position corresponding to the upper blade 12 so as to be rotatable. Further, both end portions of each slave arm 15 are pivotally supported at corresponding predetermined positions on the lower blade 11 and the upper blade 12 so as to be rotatable.

  The main arm 14 and the slave arm 15 constituting the four-bar linkage mechanism are configured to be housed in a recess formed in the lower blade 11 in a single blade state. Further, in the single blade state, the main arm 14 and the slave arm 15 are set so that the shaft support positions are arranged substantially in a straight line on one straight line, and the straight line is formed in the concave portion of the lower blade 11. It is the structure accommodated in a shape.

  In the air conditioner of the present embodiment, the control device (not shown) of the air conditioner controls the up / down wind direction changing blade 10, so that the lower blade 11 and the upper blade 12 rotate with the same distance maintained. And / or the upper blade 12 and the lower blade 11 are separated from each other. By the up-and-down air direction changing blade 10 controlled in this way, the air blown out from the outlet 2c is distributed into an air flow substantially in one direction or two directions (for example, the direction of the upper space and the direction of the lower space). It becomes possible.

  As shown in FIG. 5, when the entire lower and upper wind direction changing blades 10 rotate while the lower blade 11 and the upper blade 12 are kept at the same distance, the lower blade 11 and the upper blade 12 are moved between the lower blade 11 and the upper blade 12. The direction of the main stream flowing through the space can be changed in the vertical direction. At this time, the flow direction of the air passing between the upper blade 12 and the upper wall of the air outlet 2c (that is, the stabilizer 8) is the direction of the upper space.

  In addition, as shown in FIG. 6, the upper blade 12 performs a separation operation while maintaining the state of being substantially parallel to the lower blade 11 in a state where the position of the lower blade 11 is maintained. It is possible to distribute the air blown from 2c into an airflow that is directed substantially in one direction or in two directions (for example, the direction of the upper space and the direction of the lower space) and change the air volume. For example, when the upper blade 12 approaches the lower blade 11, the distance between the lower blade 11 and the upper blade 12 is reduced, and the distance between the upper blade 12 and the stabilizer 8 (the upper wall of the outlet 2c) is increased. Thereby, the flow rate of the air which passes between the lower blade | wing 11 and the upper blade | wing 12 toward the indoor lower space becomes small, passes between the upper blade | wing 12 and the stabilizer 8, and the air which goes to the indoor upper space. The flow rate increases.

  Thus, according to the air conditioner of the present embodiment configured as described above, it is possible to freely vary the ratio of the amount of air blown to the indoor upper space and the amount of air blown to the lower space, A comfortable air-conditioned space can be realized.

  As shown in FIG. 2A, when the distance between the lower blade 12 and the upper blade 11 is zero, that is, the up / down airflow direction changing blade 10 is located on the upstream side of the lower blade 11 and the downstream side of the upper blade 12. When the blades overlap with each other, the length of the up / down airflow direction changing blade 10 in the air flow direction is maximized. As a result, the air blown out from the outlet 2c can be supplied further.

  From here, operation | movement of the up-and-down air direction change blade | wing 10 at the time of heating and air_conditioning | cooling is demonstrated.

  FIG. 8 is a diagram illustrating an example of a specific rotation operation and separation operation of the up-and-down air direction changing blade 10 (lower blade 11 and upper blade 12) during heating. In FIG. 8, the main arm 14 and the sub arm 15 are omitted, and the lower blade 11 and the upper blade 12 are illustrated. FIG. 9 shows the upper and lower airflow direction changing blades 10 during cooling (the lower blade 11 and the upper blade). It is a figure which shows the example of the concrete rotation operation | movement of 12), and a separation / contact operation | movement. FIG. 8 and FIG. 9 show “high activity amount” and “medium activity amount” as human activity level for each of the “normal”, “strong” or “weak” operation levels of the air conditioner of the present embodiment. Or the operation | movement of the up-and-down wind direction change blade | wing 10 when the human sensitive sensor unit 18 detects "activity amount rest" is shown.

  The operation level of the air conditioner is set by the user. For example, a controller (remote controller) for operating the air conditioner is provided with a button for selecting an operation level of the air conditioner.

  During heating, it is considered that the temperature at the user's feet is high for the user. For this reason, during heating, as shown in FIG. 2B and FIG. 8, while maintaining the state in which the lower blade 11 and the upper blade 12 are parallel to each other, the vertical airflow direction changing blade 10 is directed downward (or Through the first gear unit 20 and the second gear unit 21 so that the main flow direction of the air passing between the lower blade 11 and the upper blade 12 is downward). It is preferable to control the up / down wind direction changing blade 10.

  The air (warm air) warmed inside the indoor unit 1 during heating tends to float upward from the air outlet 2c, while maintaining the state in which the lower blade 11 and the upper blade 12 are parallel to each other, Further, by controlling the up / down airflow direction changing blade 10 to be downward (or obliquely downward), the flow direction of a large amount of air blown from the air outlet 2c can be downward (or obliquely downward). As a result, as shown in FIGS. 10 to 12, the air (warm air) blown out from the air outlet 2 c of the indoor unit 1 can be supplied toward the floor surface, and the temperature at the user's feet can be increased. It becomes possible.

  In addition, during heating, when the amount of activity is large, it is preferable to warm not only the feet but also the entire room by circulating hot air over the entire wall surface including the ceiling surface and the floor surface. For this reason, as shown in FIG. 8, in the air conditioner of the present embodiment, the upper and lower airflow direction changing blades 10 are turned downward (obliquely downward) in a state of two blades, In this way, in the air conditioner of the present embodiment, air is blown out from the air outlet 2c of the indoor unit 1 as shown in FIG. 11 or FIG. Can be distributed in two directions, the direction toward the user's head and the direction toward the user's feet, and the room can be efficiently warmed to realize a heater with high energy saving performance. .

  During heating, as shown in FIG. 8, the lower blade 11 and the upper blade are rotated by rotating the main arm 14 via the upper blade drive shaft 19 with the lower blade 11 fixed obliquely downward. The control device performs control for changing the interval with the control unit 12.

  Specifically, during heating, the interval between the lower blade 11 and the upper blade 12 is based on the amount of activity of a person detected by a human sensor unit 18 which is an activity amount detection device, as shown in FIG. It is changed by a control device (not shown) of the air conditioner.

  For example, when the air conditioner is performing a heating operation at a “normal” operation level (when the user selects a heating operation at a “normal” operation level), the control device for the air conditioner is The larger the human activity level (activity level) detected by the sensation sensor unit 18 is, the closer the upper blade 12 is to the lower blade 11 and the smaller the distance between the lower blade 11 and the upper blade 12 is.

  Thereby, for example, it is suppressed that a large amount of warm air hits the feet of an active person, that is, a person with a large amount of activity and a warm body (person with a large amount of activity). More specifically, if the distance between the lower blade 11 and the upper blade 12 is reduced while the lower blade 11 is fixed obliquely downward, it passes between the lower blade 11 and the upper blade 12 and enters the lower space in the room. The flow rate of the air that flows (air flow of warm air) decreases, and the flow rate of air that passes between the upper blade 12 and the stabilizer 8 toward the indoor upper space (air flow of hot air) increases. Therefore, as shown in FIG. 12, it is suppressed that an active person ("active mass" person) existing in the lower space of the room feels excessive heat due to a large amount of hot air hitting his feet. Is done. In addition, FIG. 11 shows the case of “active amount”.

  On the other hand, when the distance in the parallel direction between the lower blade 11 and the upper blade 12 is increased in a state where the lower blade 11 is fixed obliquely downward, the amount of warm air toward the indoor lower space increases, and the indoor upper space is increased. The amount of warm air flowing toward Accordingly, as shown in FIG. 10, for example, the feet of a resting person, that is, a person with a small amount of activity and a cold body (a person with “small amount of activity”) can be warmed by a large amount of hot air.

  Thus, the person who exists indoors can obtain a comfortable heating feeling according to the amount of activity.

  In addition, when the air conditioner is performing the heating operation at the “strong” operation level, that is, when the user selects the heating operation at the “strong” operation level, as shown in FIG. Regardless of the amount of human activity detected by the human sensor unit 18, the control device of the harmony machine has a parallel distance between the lower blade 11 and the upper blade 12 with the lower blade 11 fixed obliquely downward. Is maintained in a relatively large state (for example, a maximum state). On the other hand, when the user has selected the “low” level heating operation, the lower blade 11 and the lower blade 11 are fixed obliquely downward regardless of the amount of human activity detected by the motion sensor unit 18. The distance in the parallel direction between the upper blades 12 is kept relatively small. Thereby, the person who exists indoors can obtain a desired feeling of heating.

  On the other hand, at the time of cooling, for example, when the user selects the cooling operation of the “normal” operation level, if the human activity level detected by the human sensor unit 18 is large, the control device for the air conditioner (Not shown) places the lower blade 11 obliquely downward via the lower blade drive shaft 13 and causes the upper blade 12 to be separated from the lower blade 11 by a predetermined distance via the upper blade drive shaft 19. On the other hand, when “activity rest” is detected as the activity amount level by the human sensor unit 18, the control device arranges the lower blade 11 in the substantially horizontal direction via the lower blade drive shaft 13 and the upper blade. 12 is placed on the lower blade 11, that is, the vertical wind direction changing blade 10 is put into a single blade state.

  When “high activity amount” or “medium activity amount” is detected by the human sensor unit 18, a person existing in the room is hot because the activity amount is large, and the cold air blown out from the indoor unit 1 is directly hit. It is thought that he wants. Therefore, the lower blade 11 is disposed obliquely downward, and the upper blade 12 is separated from the lower blade 11. Thereby, as shown in FIG. 14 or FIG. 15, a part of the air (cold air) blown out from the blowout port 2 c of the indoor unit 1 is blown out in the direction toward the user's head and blown out toward the user. Is done. Note that FIG. 14 shows a case where the activity amount is large, and FIG. 15 shows a case where the activity amount is medium.

  On the other hand, when “activity rest” is detected, that is, when there is a resting person, the temperature difference between the indoor upper space and the lower space is eliminated, and cold air is directly applied to the body as shown in FIG. It is considered comfortable to rest for those who are resting. Therefore, in the situation of “activity amount rest”, as shown in FIG. 2A, it is preferable to arrange the up-and-down wind direction changing blades 10 in a substantially horizontal direction in a single blade state.

  During cooling, the air (cold air) cooled inside the indoor unit 1 is heavier than warm air, and therefore descends from the air outlet 2c toward the floor. However, by arranging the vertical wind direction changing blade 10 in a substantially horizontal direction in a single blade state, the length of the vertical wind direction changing blade 10 (the length in the direction of air flow) is increased to blow out the air from the outlet 2c. Cold air can flow along the indoor ceiling. As a result, as shown in FIG. 13, it is possible to supply air (cold air) blown out from the outlet 2 c of the indoor unit 1 along the ceiling surface to the wall surface facing the wall surface on which the indoor unit 1 is installed. Become. As a result, the temperature of the indoor upper space and the lower space can be made more uniform, and air conditioning in which cold air is not directly applied to a resting person can be realized.

  When the user selects the cooling operation at the “strong” operation level, as shown in FIG. 9, the user activity detected by the air conditioner control device (not shown) human sensor unit 18. Regardless of the amount, the blades 11 are arranged obliquely downward, and the upper blades 12 are separated from the lower blades 11. On the other hand, when the user has selected the “low” level cooling operation, regardless of the amount of human activity detected by the motion sensor unit 18, the downwind direction change blade 10 is in a single blade state in a substantially horizontal direction. Deploy. Thereby, the person who exists indoors can obtain a desired cooling feeling.

  Moreover, the operation | movement of the up-and-down air direction change blade | wing 10 shown to above-mentioned FIG.8 and FIG.9 is an example operation | movement at the time of heating and air_conditioning | cooling, and operation | movement of the up-and-down air direction change blade | wing 10 is not limited to these. For example, the operation | movement which makes the up-and-down wind direction change blade | wing 10 a single blade state is not limited at the time of air_conditioning | cooling, It can be used also at the time of heating according to a condition. Moreover, the operation | movement by which the lower blade | wing 11 and the upper blade | wing 12 have a predetermined distance and are in a parallel state (two blade state) is also performed according to a condition.

  In this connection, the user selects, via the controller, whether or not to execute control of the up / down air direction changing blade 10 by the control device based on the detection result of the human sensor unit 18, that is, automatic control of the up / down air direction changing blade 10. You may comprise an air conditioner so that it can. For example, a controller (remote controller) for operating the air conditioner includes an “automatic operation start / stop button” for starting or stopping automatic control of the up / down airflow direction changing blade 10. For example, when the “automatic operation start / stop button” of the remote controller is pressed, a change in the distance between the lower blade 11 and the upper blade 12 by the control device based on the detection result of the human sensor unit 18 or the direction of the up-and-down wind direction blade 10 That is, the change in the direction of the main flow flowing through the space between the lower blade 11 and the upper blade 12 is stopped. Thereby, the user can stop the up / down wind direction changing blade 10 in a desired state by stopping the automatic control of the up / down air direction changing blade 10 at a predetermined timing. For example, the up-and-down air direction changing blade 10 can be stopped in a state where comfortable warm air is blown out toward the user. As a result, the user can obtain a desired feeling of heating.

  Moreover, you may enable a user to change the space | interval of a 1st blade | wing and a 2nd blade | wing with the controller (remote controller) which operates an air conditioner. For example, the controller includes a button for changing the interval between the lower blade 11 and the upper blade 12. Thereby, the user can adjust the space | interval of the lower blade | wing 11 and the upper blade | wing 12 as desired. Thereby, the user can obtain a desired feeling of heating.

  According to the present embodiment, it is possible to give a comfortable heating feeling to a person existing indoors, for example, a person who is active or a person who is resting.
