Description

  The present invention relates to a vertical direction wind direction adjusting device in an air conditioner.

  2. Description of the Related Art Conventionally, the configuration of a vertical air direction adjusting device for a home air conditioner has two independent vertical air direction changing blades above and below the air outlet as shown in FIG. 6 (a) or (b). There are some which are rotatably arranged. FIG. 6A shows the state of the up / down airflow direction change blades when the heating operation starts, and FIG. 6B shows the state of the up / down air direction changing blades when the heating operation is stable. In FIG. 6 (a), the vertical wind direction changing blades 15a and 15b are both adjusted to tilt forward and downward so that all warm air is blown downward. In FIG. The wind direction changing blade 15a is adjusted to an inclination as close to the horizontal as possible so as to blow out in the horizontal direction, and the vertical wind direction changing blade 15b below the outlet is adjusted to an inclination downward so as to blow out directly below, so that the warm air is changed to the horizontal direction. There is an air conditioner that blows out in both directions downward (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 6-109312

  In FIG. 6A, which is the above-described conventional configuration, when the heating operation is started, all the warm air is blown toward the floor surface, so that the vicinity of the floor of the occupant's feet can be quickly warmed. In addition, as shown in FIG. 6B, when the heating operation is stable, the hot air flowing in the horizontal direction along the ceiling surface and the hot air flowing in the downward direction along the wall surface are blown to separate the living area. It is possible to prevent hot air from being applied to the human body.

  However, in the case where the resident is at a position away from the air conditioner even at the same stable time, as shown in FIG. 6 (b), if the warm air is blown directly downward, the vicinity of the floor near the air conditioner is well warmed. The vicinity of the distant floor where the occupants are located is difficult to heat, and there is a lack of a feeling of heating at the feet, and the residential area cannot be efficiently heated, resulting in a problem that energy savings deteriorate.

  Also, in such a situation, if the inclination of the up / down wind direction changing blade 15b in the downward direction from FIG. 6 (b) is adjusted to warm the vicinity of the feet of the resident who is far away, the up / down wind direction changing blade 15b And the lower width of the blower circuit formed in the main body, the opening width of the air outlet widens, so that the hot air diffuses and rises easily. Had problems.

  Further, in the process of the indoor temperature from rising to stable, when switching from the rising state of FIG. 6 (a) to the stable state of FIG. 6 (b), it is directed toward the floor near the occupants' feet. Since the warm air that had been transferred to the warm air along the wall surface, the heating feeling of the warm air that directly warmed the feet of the occupants was temporarily reduced, causing discomfort.

Further, as shown in FIG. 6B, since the upper wall surface of the blower circuit formed in the main body is inclined downward toward the blowout port, the blown air blown down to the vicinity of the blowout port along the blower circuit is Only with the up / down wind direction changing blades 15a above the outlet, the wind direction is difficult to bend suddenly from the downward direction to the horizontal direction. As a result, especially when there is a large amount of air or when the blowing temperature is low, not only during heating but also during cooling, the blowing air is not bent in the horizontal direction and blown downward from the horizontal only with the up / down air direction changing blades. As a result, there was a problem that the residents were uncomfortable when the blowing wind hit directly.

  This invention solves such a conventional subject, and it aims at providing the air conditioner excellent in the energy-saving property which creates a comfortable air-conditioning environment and air-conditions a room more efficiently.

  In order to solve the above-described conventional problems, an air conditioner according to the present invention includes a blowout port formed on an outlet side of a blower circuit, and a first vertical airflow direction provided so as to be rotatable about a first rotation axis. A change blade, a second up / down air direction change blade provided to be rotatable about the second rotation axis, and a third up / down air direction change blade provided to be rotatable about the third rotation axis. The first rotating shaft is provided between an upper end and a lower end of the outlet, the second rotating shaft is provided substantially close to the first rotating shaft, and the third rotating shaft is provided. Is provided near the lower end of the outlet.

  This makes it possible to adjust the strength and vertical direction of the hot and cold winds for the downward blowing air according to the occupants in the living room, and at the same time, the substantially horizontal or upward blowing air does not directly apply hot or cold air to the person. Thus, it becomes possible to circulate hot air and cold air more efficiently throughout the room.

  The air conditioner of the present invention can deliver more comfortable cold / warm air suitable for each resident in air conditioning, and at the same time, can efficiently air-condition the entire room, improving comfort and energy saving at the same time. be able to.

(Embodiment 1)
FIG. 1 shows a cross-sectional view of the air conditioner during operation. In the figure, an air conditioner 1 includes a heat exchanger 3 inside a main body and a blower fan 4 that circulates blown air in a room. The heat exchanger 3 is disposed on the upstream side of the blower fan 4. In addition, the air conditioner 1 has a suction port 6 for sucking indoor air on the top side of the main body, a blowout port 5 that blows out air-conditioned air arranged near the lower part on the front side of the main body from the front part on the bottom surface side of the main body, A front panel 7 is provided above the blowout port 5 on the front side of the main body.

  The blower circuit 2 from the blower fan 4 to the blowout port 5 includes an upper wall surface 12a and a lower wall surface 12b formed in the main body. The upper wall surface 12a is formed substantially horizontally or upward in the downstream direction of the air flow.

  The outlet 5 is provided with three first, second, and third up / down airflow direction changing blades 8a, 8b, and 8c. One end of each of these up-and-down air direction changing blades 8a, 8b, 8c is provided with first, second and third rotating shafts 9a, 9b, 9c which are mechanically coupled to the output shaft of the motor. ing. The first rotating shaft 9a of the first up / down air direction changing blade 8a and the second rotating shaft 9b of the second up / down air direction changing blade 8b are substantially close to each other between the upper end and the lower end of the outlet 5. Is arranged. The third up / down airflow direction changing blade 8 c is arranged with the third rotation shaft 9 c approximately close to the lower end of the outlet 5.

  Thereby, the 1st blowing air path 13a is formed between the upper side wall surface 12a of the ventilation circuit 2, and the upper surface side of the 1st up-and-down air direction change blade | wing 8a, and the lower surface side of the 2nd up-and-down air direction change blade | wing 8b A second blowing air passage 13b is formed between the third up / down air direction changing blade 8c.

  In addition, the air conditioner 1 is constituted by left and right wind direction changing blades, a heat exchange temperature detector, a microcomputer, and the like.

  Such an air conditioner 1 is installed and used with the back of the main body facing an indoor wall. The blower fan 4 circulates the indoor air that has entered through the suction port 6 through the heat exchanger 3 as warm air and cold air. And each up-and-down air direction change blade | wing 8a, 8b, 8c can be driven independently, and an up-and-down air direction can be changed.

  Next, FIGS. 2A to 2F show the air flow control operation during heating of the three up / down air direction change blades by the air direction control device of the air conditioner of the present embodiment.

  In FIG. 2A, the first up / down wind direction changing blade 8a is upstream with the other end (the end in the longitudinal direction opposite to the first rotating shaft 9a) facing the first rotating shaft 9a upward. The first blowout air passage 13a that blows out substantially horizontally or upward is closed by turning the end portion close to the upper wall surface 12a of the blower circuit 2.

  Further, the first up-and-down air direction changing blade 8a is inclined downward so as to continue to the upstream side of the second up-and-down air direction changing blade 8b that forms the upper wall surface of the second blowing air passage 13b that blows out downward. The upper wall surface of the second blowing air passage 13b is formed. At this time, the second up / down air direction changing blade 8b is substantially parallel to or slightly downward from the first up / down air direction changing blade 8a. The third up / down airflow direction changing blade 8c forms a lower side wall surface of the second blowout air passage 13b that is continuous with the lower side wall surface 12b of the blower circuit 2. At this time, the third up / down air direction changing blade 8c is substantially parallel to the second up / down air direction changing blade 8b.

As a result, all blown air from the blower circuit 2 is formed by the upper wall surface formed by the first up / down air direction changing blade 8a and the second up / down air direction changing blade 8b and the third up / down air direction changing blade 8c. Only the second blowing air 11 directed downward can be generated by passing through the second blowing air passage 13b between the lower wall surface.

  On the other hand, in FIG. 2B and FIG. 2C, the end portion in the longitudinal direction on the opposite side to the first rotating shaft 9a of the first vertical airflow direction changing blade 8a is arranged as shown in FIG. The first blowout air passage 13a that blows out substantially horizontally or upward is opened by rotating further downstream and opening between this end and the upper wall surface 12a of the blower circuit 2. As a result, the blower circuit 2 is branched into a second blowout air passage 13b that blows downward and a first blowout air passage 13a that blows out substantially horizontally or upward, and the first blowout air 10 that is substantially horizontal or upward and downward. The second blowing air 11 can be generated simultaneously.

  Thus, by adjusting the rotation angle of the first up / down air direction changing blade 8a, the longitudinal end and the upper side of the first up / down air direction changing blade 8a opposite to the first rotating shaft 9a are arranged. By changing the opening width between the wall surface 12a and the flow rate of the first blowing air passage 13a which blows out substantially horizontally or upward, the first blowing air 10 which is substantially horizontal or upward and the first air flow 10 which is downwardly directed. The air volume distribution with the two blowing airs 11 can be adjusted.

  For example, in FIG. 2B, when the air volume distribution of the first blown air 10 in a substantially horizontal or upward direction is adjusted to about 20% and the air volume distribution with the second blown air 11 downward is adjusted to about 80%. In FIG. 2 (c), by adjusting the opening width to a greater extent, the air volume distribution of the first blown air 10 in a substantially horizontal or upward direction is about 50%, and the second blown air 11 in the downward direction. When the air volume distribution is adjusted to about 50%.

  Since the upper wall surface 12a of the blower circuit 2 is formed substantially horizontally or upward in the downstream direction, the longitudinal direction opposite to the first rotating shaft 9a of the first up-and-down air direction changing blade 8a. Regardless of the variation of the opening width between the end of the upper wall 12a and the upper wall surface 12a, the air can always be blown out substantially horizontally or upward, and a comfortable heating environment in which the occupant does not feel the airflow can be provided.

  Further, the front panel 7 inclined forward is provided on the front side of the main body at the upper part of the outlet 5 of the air conditioner 1, thereby attracting the first blowing air 10 that is substantially horizontal or upward to the front panel 7. It is possible to blow out in a more upward direction, and it is possible to provide a comfortable heating environment that does not make the occupant feel a sense of airflow.

  Further, as shown in FIG. 2D, the opening width of the first blowing air passage 13a blown out substantially horizontally or upward is maintained at the same opening width as that in FIG. 2C, and the second blowing air blown out downward. The rotation angle of each of the second up / down air direction changing blade 8b and the third up / down air direction changing blade 8c forming the path 13b is set so that the second up / down air direction changing blade 8b is more downward than in FIG. No. 3 vertical wind direction changing blade 8c is adjusted to be more upward.

  As a result, the end portion of the second up-and-down air direction changing blade 8b on the opposite side to the second turning shaft 9b and the third turning shaft 9c of the third up-and-down air direction changing blade 8c on the opposite side. Is adjusted so that the opening width of the second blowing air passage 13b is made narrower, and the air flow rate of the second blowing air passage 13b blowing downward is reduced. As a result, it is possible to adjust the air volume distribution to be larger in the first blowing air 10 that is substantially horizontal or upward than in the second blowing air 11 that is downward. For example, FIG. 2D shows a case where the air volume distribution of the first blown air 10 that is substantially horizontal or upward is adjusted to about 70%, and the air volume distribution with the downward air flow is adjusted to about 30%.

As described above, in this embodiment, in any of the cases shown in FIGS. 2B to 2D, the first direction to the substantially horizontal or upward direction is not changed without changing the wind direction of the downward blowing air 11. The air volume distribution between the blowing air 10 and the second blowing air 11 downward can be varied.

  Further, in FIG. 2E, the second up-and-down air direction is maintained with the opening width of the second blowing air passage 13b being substantially equal to the opening width of the second blowing air passage 13b in FIG. The change blade 8b and the third up / down wind direction change blade 8c are adjusted downward. Thus, the vertical airflow direction of the second blown air 11 is maintained while maintaining the air volume distribution between the first blown air 10 that is substantially horizontal or upward and the second blown air 11 that is directed downward in FIG. Can be adjusted downward.

  In FIG. 2 (f), the second up / down air direction change is performed while the opening width of the second blowing air passage 13b is substantially equal to the opening width of the second blowing air passage 13b in FIG. 2 (b). The blade 8b and the third up / down air direction changing blade 8c are adjusted upward. Thus, the vertical airflow direction of the second blown air 11 is maintained while maintaining the air volume distribution between the first blown air 10 that is substantially horizontal or upward in FIG. 2B and the second blown air 11 that is directed downward. Can be adjusted more upward.

  As described above, in the present embodiment, the second blowing air 11 is maintained while maintaining the air volume distribution between the first blowing air 10 that is substantially horizontal or upward and the second blowing air 11 that is downward. Up and down wind direction can be changed.

  Next, Fig.3 (a)-(f) shows the flow of the air in a room in each airflow control operation at the time of heating in Fig.2 (a)-(f).

  In FIG. 3 (a), all the blowing winds can be concentrated in the direction of the floor where the occupants are located to quickly warm the living area where the occupants are located near the center of the room. It is possible to provide a more comfortable heating environment when entering.

  3 (b) to 3 (d), the substantially horizontal or upward blowing air circulates from the ceiling to the floor facing the wall where the air conditioner 1 is installed and further to the floor behind the occupant. Heating and air conditioning with excellent energy efficiency by warming the entire room efficiently, and at the same time, the downward blowing air blows out toward the floor in front of the occupant's feet so that the occupant is not directly exposed to the warm air Accordingly, the area around the feet of the occupants can be warmed, and a more comfortable heating environment can be provided without causing the occupants to feel the airflow.

  Further, in a situation where the resident wants to warm his feet, adjust the air volume distribution of the blowing air to be lower than the blowing air to be almost horizontal or upward, as shown in FIG. 3 (b). Can do. On the other hand, in a situation where the resident wants to feel as little as possible the warm airflow to the feet, as shown in FIG. 3 (d), the amount of the blowing air that is directed downward rather than the blowing air that is substantially horizontal or upward. The distribution can be adjusted to be smaller, and in any case, the intensity of the heating feeling and the warm air can be adjusted without changing the direction of the downward blowing air that is optimally adjusted according to the location of the resident. Since the amount of hot air blown out according to the resident's preference such as the strength of the airflow can be adjusted, an optimal heating environment can be provided for each resident.

In addition, when a resident who prefers to feel as little as possible the warm air flow in FIG. 3D moves to a place close to the air conditioner as shown in FIG. While maintaining a state where the air volume distribution of the downward blowing air flow is less adjusted than the upward blowing air flow, the downward blowing air flow direction is adjusted so that it blows out in front of the resident. In addition, by heating the vicinity of the feet so as not to feel the warm air feeling, it is possible to provide a comfortable heating environment even when the resident moves nearby. In addition, by blowing out a substantially horizontal or upward blowing air that does not directly hit the occupant's body at the same time, it is possible to secure a sufficient amount of air to circulate in the living room without reducing the entire air volume of the blowing air. Heating and air-conditioning that is efficiently heated and excellent in energy saving can be realized.

  In addition, when a resident who wants to warm his feet in FIG. 3 (b) moves to a location farther away from the air conditioner as shown in FIG. 3 (f), the blowing air is almost horizontal or upward. While maintaining a state where the air volume distribution of the downward blowing air is more adjusted, the downward blowing air direction is adjusted so that it blows upward slightly toward the distance, and warm air is blown around the resident's feet. By warming the vicinity of the feet in such a way that it can be delivered sufficiently, a comfortable heating environment can be provided even when the resident moves far away.

  Therefore, even if a resident's whereabouts change, it can always adjust to the optimal up-and-down direction according to a resident's demand, and can provide a more comfortable heating environment according to a resident's liking. . In addition, when a means for detecting the position of a person with a sensor or the like is provided, it is possible to automatically adjust the wind direction to the optimum vertical direction.

  FIG. 3 (g) shows the air flow by each air flow control operation during heating in FIG. 2 (e), but furniture such as sofas and storage shelves placed on the floor in the living room. The case where the resident was before and behind the obstacles 14, such as a fixture, is shown.

  In this case, the downward blowing wind warms the vicinity of the feet of the resident in front of the obstacle 14, and the substantially horizontal or upward blowing wind is not obstructed by the obstacle 14 and faces the wall of the air conditioner 1 from the ceiling. The warm air circulates along the path, and the space where the occupants are behind the obstacle 14 can also be warmed. As a result, even when the obstacle 14 that hinders the arrival of hot air is on the floor, not only the resident in front of the obstacle 14 but also the resident in the back can deliver hot air at the same time. While satisfying the feeling of heating of both residents, it is possible to realize a more efficient and energy efficient heating air conditioning.

  In addition, even when the preferred temperature differs between the resident in the front and the resident in the back, for example, if the resident's living area in the back prefers a higher temperature than the resident in the front, the downward By adjusting the air volume distribution of the blowing air to be almost horizontal or upward rather than the blowing air, the living area of the resident in the back can be made higher than the living area of the resident in the foreground. Even if there are residents with different preferred temperatures in the same room, both residents can provide a comfortable heating environment by adjusting the temperature around each residents to the preferences of each residents. it can.

Further, as the room temperature detected by a room temperature sensor (not shown) provided in the air conditioner 1 is determined in advance by a resident and approaches a set temperature stored in a memory or the like of a control device (not shown). The airflow control operation of the airflow direction control device is controlled so as to be automatically changed in the order of FIGS. 2A, 2B, 2C, and 2D. That is, at the start of operation, the end of the first up / down air direction changing blade 8a is brought close to the upper wall surface 12a of the blower circuit 2, thereby closing the first blowing air passage 13a that blows out substantially horizontally or upward. The second up / down air direction changing blade 8b forms the upper wall surface of the second blowing air passage 13b together with the first up / down air direction changing blade 8a. The third up / down air direction changing blade 8c is substantially parallel to the second up / down air direction changing blade 8b (FIG. 2A). Thereafter, the first up / down airflow direction changing blade 8a is further rotated to increase the opening width of the first blowing air passage 13a (FIGS. 2B to 2C). Thereafter, the second up-and-down air direction changing blade 8b is lowered and the second up-and-down air direction changing blade 8c is raised, thereby reducing the opening width of the second blowing air passage 13b (FIG. 2D).

  As a result, the air volume distribution of the first blown air 10 that is substantially horizontal or upward is gradually increased as it approaches the stable time from the start of operation. In this way, in the process from the rise to the stability of the room temperature, the resident is compensated for the decrease in the feeling of heating by gradually decreasing the amount of downward warm air directed toward the floor of the resident's feet. Increases the amount of warm air in a generally horizontal or upward direction that circulates throughout the room without direct hot air, gradually warming the entire room and maintaining a feeling of heating without causing the residents to feel the airflow Therefore, it is possible to realize a heating and air-conditioning system that always achieves both comfort and energy saving from the rise to the stability of the room temperature without requiring the operation of the resident.

  Next, FIGS. 4A to 4G show air flow control operations at the time of cooling of the three up / down air direction changing blades by the air direction control device of the air conditioner of the present embodiment.

  In FIG. 4A, the other end of the first up / down airflow direction changing blade 8a with respect to the first rotation shaft 9a (the end portion in the longitudinal direction opposite to the first rotation shaft 9a) is directed upstream. The first blowout air passage 13a that blows out substantially horizontally or upward is closed by turning the end portion close to the upper wall surface 12a of the blower circuit 2.

  Further, the first up-and-down air direction changing blade 8a is inclined downward so as to continue to the upstream side of the second up-and-down air direction changing blade 8b that forms the upper wall surface of the second blowing air passage 13b that blows out downward. The upper wall surface of the second blowing air passage 13b is formed. At this time, the second up / down air direction changing blade 8b is substantially parallel to or slightly upward from the first up / down air direction changing blade 8a. The third up / down airflow direction changing blade 8c forms a lower side wall surface of the second blowout air passage 13b that is continuous with the lower side wall surface 12b of the blower circuit 2. At this time, the third up / down air direction changing blade 8c is substantially parallel to the second up / down air direction changing blade 8b.

  As a result, all the blown air from the blower circuit 2 is formed by the upper wall surface formed by the first up / down air direction changing blade 8a and the second up / down air direction changing blade 8b, and the bottom formed by the third up / down air direction changing blade 8c. Only the second blowing air 11 that is directed downward is generated through the second blowing air passage 13b between the side wall surface and the second blowing air passage 13b.

  On the other hand, in FIG. 4B and FIG. 4C, the end portion in the longitudinal direction on the opposite side to the first rotating shaft 9a of the first up-and-down air direction changing blade 8a is arranged as shown in FIG. The first blowout air passage 13a that blows out substantially horizontally or upward is opened by rotating further downstream and opening between this end and the upper wall surface 12a of the blower circuit 2. As a result, the blower circuit 2 is branched into a second blowout air passage 13b that blows downward and a first blowout air passage 13a that blows out substantially horizontally or upward, and the first blowout air 10 that is substantially horizontal or upward and downward. The second blowing air 11 can be generated simultaneously.

  Thus, by adjusting the rotation angle of the first up / down air direction changing blade 8a, the longitudinal end of the first up / down air direction changing blade 8a opposite to the rotating shaft 9a and the upper wall surface 12a The first blowing air 10 that is substantially horizontal or upward and the second blowing air that is downward are changed by increasing or decreasing the air flow rate of the first blowing air passage 13a that blows out substantially horizontally or upward. The air volume distribution with the wind 11 can be adjusted. For example, in FIG. 4B, when the air volume distribution of the first blown air 10 in a substantially horizontal or upward direction is adjusted to about 20% and the air volume distribution to the second blown air 11 in the downward direction is adjusted to about 80%. Indicates.

Further, in FIG. 4C, the opening width between the end portion in the longitudinal direction opposite to the first rotation shaft 9a of the first up / down air direction changing blade 8a and the upper wall surface 12a is adjusted to be larger. At the same time, the rotation angle of each of the second up / down air direction changing blade 8b and the third up / down air direction changing blade 8c forming the second blowing air passage 13b that blows downward is set to a second up / down direction from FIG. 4 (b). The wind direction changing blade 8b is adjusted downward, and the third vertical wind direction changing blade 8c is adjusted upward.

  As a result, the end portion of the second up-and-down air direction changing blade 8b on the opposite side to the second turning shaft 9b and the third turning shaft 9c of the third up-and-down air direction changing blade 8c on the opposite side. Is adjusted so that the opening width of the second blowing air passage 13b is made narrower, and the air flow rate of the second blowing air passage 13b blown downward is reduced. It can be adjusted so that the air volume distribution is larger in the first blowing air 10 in the horizontal or upward direction than in the second blowing air 11 in the downward direction. For example, in FIG. 4C, when the air volume distribution of the first blown air 10 in a substantially horizontal or upward direction is adjusted to about 70% and the air volume distribution with the second blown air 11 downward is adjusted to about 30%. Indicates.

  As described above, in the present embodiment, in either case of FIG. 2B or FIG. 2C, the first direction to the substantially horizontal or upward direction is changed without changing the wind direction of the blowing air 11 downward. The air volume distribution between the one blowing air 10 and the second blowing air 11 downward can be varied.

  Since the upper wall surface 12a of the blower circuit 2 is formed to be substantially horizontal or upward in the downstream direction, the first vertical airflow direction changing blade 8a is in the longitudinal direction opposite to the first rotating shaft 9a. Regardless of the variation in the opening width between the end of the upper wall 12a and the upper wall surface 12a, the air can be blown out substantially horizontally or upward, and a comfortable cooling environment in which the occupant does not feel the airflow can be provided.

  Further, by providing the front panel 7 inclined forward on the front side of the main body above the outlet 5 of the air conditioner 1, the first blowing air 10 that is substantially horizontal or upward is attracted to the front panel 7. The air can be blown upward, and a comfortable cooling environment that does not make the occupant feel a further airflow can be provided.

  Further, in FIG. 4D, the opening width between the end portion in the longitudinal direction opposite to the first rotating shaft 9a of the first up / down air direction changing blade 8a and the upper wall surface 12a is adjusted to be larger. In addition, a lower side wall surface of the first blowing air passage 13a that is substantially horizontal or upward is formed, and the second vertical air direction changing blade 8b is also adjusted to substantially the same rotational angle as the first vertical air direction changing blade 8a. In addition, the lower side wall surface of the upward first blowing air passage 13a is formed, and the end in the longitudinal direction on the side that is not substantially close to the vicinity of the lower end of the blowing port 5 of the third up / down air direction changing blade 8c By making it close to the up-and-down air direction changing blade 8b, the downward second blowing air passage 13b is closed, and the first up-and-down air direction changing blade 8a and the second up-and-down air direction changing blade 8b are substantially horizontal or upward. 1st blowing air passage 13a To form the lower wall.

  Accordingly, all the blown air from the blower circuit 2 is formed by the first blown air passage formed by the first up / down air direction changing blade 8a, the second up / down air direction changing blade 8b, and the third up / down air direction changing blade 8c. Only the first blown air 10 which is ventilated between the lower side wall surface 13a and the upper wall surface 12a of the blower circuit 2 and substantially horizontal or upward can be generated.

  Further, in FIG. 4 (e), the second up-and-down air direction is maintained with the opening width of the second blowing air passage 13b being substantially equal to the opening width of the second blowing air passage 13b in FIG. 4 (c). The change blade 8b and the third up / down wind direction change blade 8c are adjusted downward. Accordingly, the vertical airflow direction of the second blown air 11 is maintained while maintaining the air volume distribution between the first blown air 10 that is substantially horizontal or upward and the second blown air 11 that is directed downward in FIG. Can be adjusted downward.

  In FIG. 4 (f), the second up-and-down air direction is maintained with the opening width of the second blowing air passage 13b being substantially equal to the opening width of the second blowing air passage 13b in FIG. 4 (b). The change blade 8b and the third up / down air direction change blade 8c are adjusted more upward. Accordingly, the vertical airflow direction of the second blown air 11 is maintained while maintaining the air volume distribution between the first blown air 10 that is substantially horizontal or upward and the second blown air 11 that is directed downward in FIG. Can be adjusted more upward.

  As described above, in the present embodiment, the second blowing air 11 is maintained while maintaining the air volume distribution between the first blowing air 10 that is substantially horizontal or upward and the second blowing air 11 that is downward. Up and down wind direction can be changed.

  Further, in FIG. 4G, the opening width between the end portion in the longitudinal direction opposite to the first rotating shaft 9a of the first up / down air direction changing blade 8a and the upper wall surface 12a is adjusted to be larger. In addition, a lower side wall surface of the first blowing air passage 13a that is substantially horizontal or upward is formed, and the second vertical air direction changing blade 8b is also adjusted to substantially the same rotational angle as the first vertical air direction changing blade 8a. Or a lower side wall surface of the upward first blowing air passage 13a, and the third up-and-down air direction changing blade 8c and the second end in the longitudinal direction on the side not substantially close to the vicinity of the lower end of the blowing port 5 By opening the space between the up / down airflow direction changing blades 8b and adjusting the rotation angle to be substantially horizontal, a lower side wall surface of the second blowing air passage 13b that is substantially horizontal or upward is formed.

  As a result, the blowing air 10 from the first blowing air passage 13a and the blowing air 11 from the second blowing air passage 13b can be substantially horizontal or upward blowing air, as shown in FIG. Similarly, only a substantially horizontal or upward blowing wind can be generated.

  Next, FIGS. 5A to 5F show the air flow in the room in each airflow control operation during cooling in FIGS. 4A to 4F.

  In addition, since the air flow of FIG.4 (g) is the same as that of FIG.5 (d) which shows the airflow of FIG.4 (d), illustration is abbreviate | omitted.

  In Fig. 5 (a), it is possible to quickly cool the living area where there is a resident near the center of the room by concentrating the blowout air in the direction where the resident is 100%. It is possible to provide a more comfortable air-conditioning environment when it comes to the site.

  5B to 5C, the substantially horizontal or upward blowing air is circulated from the ceiling through the facing wall to the floor behind the occupant to efficiently cool the entire room for energy saving. At the same time as realizing excellent cooling and air conditioning, the downward blowing air blows out toward the resident's upper body, making it possible to cool the resident's upper body while preventing the cold air from directly hitting the resident's feet. It is possible to provide a more comfortable cooling environment that gives a feeling of coolness without cooling the person's feet.

  Furthermore, in a situation where the resident wants to strengthen the cold wind that hits the upper body, as shown in FIG. 5B, adjustment is made so that the air volume distribution of the blowing air downward is larger than the blowing air blowing substantially horizontally or upward. can do. On the other hand, in a situation where the resident wants to weaken the cold wind that hits the upper body, as shown in FIG. 5C, adjustment is made so that the air volume distribution of the downward blowing air is smaller than the substantially horizontal or upward blowing air. In any case, it can meet the resident's preference such as the strength of the cooling feeling and the strength of the feeling of airflow without changing the direction of the downward blowing air that is optimally adjusted according to the location of the resident. Since the amount of cool air blown out can be adjusted, it is possible to provide an optimal cooling environment for each resident.

  In addition, when a resident who prefers that the weak cold air in FIG. 5 (c) hits the upper body moves to a place close to the air conditioner as shown in FIG. While maintaining a state where the air volume distribution of the blowing air to the downward direction is less adjusted than the blowing air, the downward blowing air direction is adjusted to blow slightly toward the upper body of a nearby resident. However, it is possible to provide a comfortable cooling environment even when the resident moves nearby by making the upper body of the resident feel weak cold air. In addition, by blowing out a substantially horizontal or upward blowing air that does not directly hit the occupant's body at the same time, it is possible to secure a sufficient amount of air to circulate in the living room without reducing the entire air volume of the blowing air. Cooling air-conditioning that is efficiently cooled and excellent in energy saving can be realized.

  When a resident who prefers the strong cold air in FIG. 5B to hit the upper body moves to a location farther away from the air conditioner as shown in FIG. Maintaining a state where the air volume distribution of the blowout air is adjusted more downward than the wind, and further adjusting the direction of the blowout air flow downward so that it blows upward slightly toward the distance, stronger cold air on the upper body of the resident It is possible to provide a comfortable cooling environment even when a resident moves far away.

  Therefore, even if a resident's whereabouts change, it can always adjust to the wind direction of the optimal up-and-down direction according to a resident's demand, and a resident can deliver more comfortable cold wind to a resident. In addition, when a means for detecting the position of a person with a sensor or the like is provided, it is possible to automatically adjust the wind direction to the optimum vertical direction.

  Moreover, in FIG.5 (d), the more comfortable cooling environment which makes a resident feel no airflow at the time of cooling can be provided by blowing all the blowing winds upward toward the ceiling.

  Further, as the room temperature detected by the room temperature sensor provided in the air conditioner approaches the set temperature, the airflow control operation of the wind direction control device is shown in FIGS. 4 (a), 4 (b), 4 (c), Control is performed so as to be automatically varied in the order of FIG. That is, at the start of operation, the end of the first up / down air direction changing blade 8a is brought close to the upper wall surface 12a of the blower circuit 2, thereby closing the first blowing air passage 13a that blows out substantially horizontally or upward. The second up / down air direction changing blade 8b forms the upper wall surface of the second blowing air passage 13b together with the first up / down air direction changing blade 8a. The third up / down air direction changing blade 8c is substantially parallel to the second up / down air direction changing blade 8b (FIG. 4A). Thereafter, the first up / down airflow direction changing blade 8a is further rotated to increase the opening width of the first blowout air passage 13a (FIGS. 4B to 4C). Thereafter, the second up / down air direction changing blade 8b and the second up / down air direction changing blade 8c are raised, and the downward second blowing air passage 13b is closed (FIG. 4D).

  As a result, the air volume distribution of the first blown air 10 that is substantially horizontal or upward is gradually increased as it approaches the stable time from the start of operation. As a result, in the process from the rise of the room temperature to the stability, the resident directly receives cold air to compensate for the decrease in cooling sensation caused by gradually reducing the amount of downward cold air directed toward the upper body of the resident. The entire room is gradually cooled by increasing the amount of cold air that circulates through the entire room without hitting it, and the cooling feeling is maintained without causing the occupant to feel a sense of airflow. Therefore, it is possible to realize a cooling air-conditioning that always achieves both comfort and energy saving from the rise to the stability of the room temperature without the need for labor.

According to the above embodiment, by adjusting the air volume distribution and the up and down wind direction of the downward blowing air and the substantially horizontal or upward blowing air, the downward blowing air can be used for the resident's preference, activity status, and whereabouts in the room. Furthermore, to provide an air conditioning environment suitable for each person's experience by adjusting the strength of the hot and cold air and the vertical direction of the wind in accordance with the installation conditions of the furniture in the living room, the operating condition of the air conditioning, etc. At the same time, the substantially horizontal or upward blowing air can always efficiently circulate hot air and cold air throughout the room, thereby realizing air-conditioning and air-conditioning with more energy saving.

  The air conditioner according to the present invention can achieve efficient and energy-saving air conditioning without impairing the comfort of each resident in air conditioning in a living room. It can be applied not only to a harmony machine, but also to a business air conditioner used in an office or the like.
