Description

  The present invention relates to a configuration of a vertical direction wind direction changing blade in an air conditioner.

  Conventionally, as shown in FIG. 8 (a) or FIG. 9 (a), the configuration of the up-down direction wind direction changing blades of the home air conditioner is arranged so that the up-down direction wind direction changing blades 8 are rotatable around the diffuser 2. As shown in FIG. 8 (b) or FIG. 9 (b), the type is roughly classified into a type that is rotatably disposed near the water tray. FIGS. 8A and 9B show the rotation stop position of the vertical direction wind direction change blades during cooling in each type, and FIGS. 8B and 9A show the vertical direction wind direction changing blades during heating in each type. (Example) is shown.

  As another configuration, the upper and lower blades are provided as upper and lower airflow direction control plates, the upper and lower blades of the upper and lower airflow direction control plates are directed downward, and the upper blades of the upper and lower airflow direction control plates are An air conditioner that is directed downward from a position parallel to the lower blade of the vertical wind direction control plate, and directed downward from a position parallel to the upper blade of the vertical wind direction control plate. 10 (a) to 10 (c)) (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 5-60365

  However, in FIG. 8A, which is the above-described conventional configuration, during the cooling operation, the cool air 11 is blown in the horizontal direction or the upward direction along the vertical direction wind direction change blade and the shape of the blade. It is possible to carry cold air far from the room. As a result, a comfortable environment with less airflow feeling can be created without directly applying cold air to a person, and the entire room can be efficiently cooled. However, like the warm air 10 in FIG. 9A, during the heating operation, an air flow 10 'having a temperature higher and lighter than that of the surrounding air is generated and separated from the vertical direction wind direction change blades. Accordingly, the reachability to the floor surface direction is deteriorated as in the hot air 19 in FIG. 12, and the entire room cannot be efficiently heated, resulting in a problem that energy saving is deteriorated.

  Further, in the configuration of FIG. 8B, the warm air 10 that is lighter and warmer than the surrounding air during the heating operation is suppressed by the vertical wind direction changing blade and the blade shape, so that the warm air 20 in FIG. The reachability to the floor is improved. However, as shown in FIG. 13 (a), a resident who is relatively close to the air outlet of the air conditioner sets the normal air volume to reduce discomfort caused by feeling warm air on the body as much as possible. When the adjustment is made to weaken, the warm air reaches only to the occupants' feet, and the entire living room including the ceiling and the wall surface is not warmed, so that the feeling of heating is lowered. Under such circumstances, if the resident tries to increase the preset temperature to maintain the sensation, the resident has a problem that efficient heating cannot be performed and energy saving performance is deteriorated.

Further, as shown in FIG. 13B, when all the blowing air is blown downward, the blowing air hits the obstacle 16 and circulates in the space in front of the obstacle 16. The space is not warmed, and the feeling of heating of the occupants in the back of the obstacle 16 decreases. Further, under such circumstances, if a resident behind the obstacle 16 increases the set temperature to maintain the sensation, not only efficient heating cannot be performed and energy saving performance deteriorates, but also the obstacle 16 For the residents in the foreground, there was a problem that the comfort level was lowered due to being too warm.

  In the configuration of FIG. 9B, the cool air 11 having a temperature lower and heavier than that of the surrounding air during the cooling operation is peeled off from the vertical wind direction changing blades to generate the cool air 11 ′, as shown in FIG. 18 cannot be carried far away from the room, and the blown cold wind directly hits the occupants and makes them feel chilly. Also, the entire room cannot be cooled efficiently and energy savings are deteriorated. Was.

  In addition, as shown in FIG. 14, when the resident near the center of the living room makes adjustments to reduce the setting of the blowout air amount in order to weaken the feeling of cold wind directly hitting the body, However, since the entire living room including the ceiling and the wall surface is not cooled, the cooling feeling is lowered. Further, under such circumstances, if the resident tries to maintain the sensation by lowering the set temperature due to heat, there is a problem that efficient cooling cannot be performed and energy saving performance deteriorates.

  In the air conditioner described in the above-mentioned patent document 1, the wind speed can be increased by the effect of constricting the hot air, and the reachability of the cold air and the hot air can be improved. And the same problem as the configuration of FIG. 9B during cooling.

  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 problems, the present invention provides a blowout port formed on the outlet side of a blower circuit, a first vertical wind direction change blade that changes the vertical wind direction, and a second vertical wind direction change blade. A first arm portion for holding the first up-and-down wind direction changing blade, and an upstream end of the second up-and-down air direction changing blade on the other end side that is rotatably held in the main body. A second arm portion that rotatably holds the portion, and contacts an end portion of the first vertical wind direction change blade on the first arm portion side with an upper surface of the second vertical wind direction change blade as to the first vertical direction while being close to the junction of the air direction changing blade and said first said junction with the arm portion of the second vertical wind direction changing blade and said second arm portion in the position of the contiguous portion by changing between near the top and near the lower end of the outlet, the first Thereby changing the air volume distribution between the blowoff air flow passing through the lower side of the blowoff air flow passing through the upper surface side of the downward wind direction changing blades and the second vertical wind direction changing blade, while being the proximity, the second The airflow direction of the blowing air passing through the lower surface of the second airflow direction changing blade is changed by rotating the airflow direction changing blade .

  Thus, according to the present invention, it is possible to provide an air conditioner that achieves both comfort and energy saving in cooling and heating by freely driving two up-and-down airflow direction change blades.

The second arm portion 6b is rotatably held at one end side in the main body, and the second up-down direction wind direction changing blade 8b is rotatably held at the other end side. The first up / down direction wind direction changing blade 8a is attached to the first arm portion 6a so that the curved concave surface faces frontward or upward in a state of being horizontal with respect to the first arm portion 6a. On the other hand, the second up-and-down direction wind direction changing blade 8b is attached to the first arm portion 6a so that the curved convex surface faces forward or upward in a state where it is horizontal with respect to the second arm portion 6b.

  In addition, the air conditioner 1 is provided with a left-right airflow direction change blade, a heat exchange temperature detector, a microcomputer, and the like. Note that it is desirable to employ a cross flow fan as the blower fan 4.

  FIG. 2 is an exploded perspective view of the vertical direction wind direction changing blade and the arm portion. Since the basic structure of the two sets of the up / down direction wind direction changing blades and the arms is the same, the structure will be described based on the second up / down direction wind direction changing blades 8b and the second arm unit 6b. Description of the detailed structure of the change blade 8a and the first arm portion 6a is omitted.

  The second arm portion motor 13b, which is a drive device for rotating the second arm portion 6b, is disposed between the diffuser 2 and the water tray 12 in the depth direction of the drawing, and the second arm portion motor 13b. The second arm portion 6b coupled to the output shaft 13b ′ of the second up-down direction wind direction changing blade 8b is configured to freely rotate 7 in front of the air outlet 5 around the output shaft 13b ′. The arrangement can be freely moved between the vicinity of the upper end and the lower end of the outlet 5.

  In addition, a second blade motor 14b, which is a driving device for rotating the second vertical wind direction changing blade 8b, is disposed at one end of the second arm portion 6b, and the other end of the second arm portion 6b. The shaft of the arranged second up-down direction wind direction changing blade 8b and the output shaft 14b ′ of the second blade motor 14b are mechanically coupled. For this reason, the 2nd up-down direction wind direction change blade | wing 8b can rotate 9 freely, and can change the up-down direction wind direction of the airflow which passes the circumference | surroundings of the 2nd up-down direction wind direction change blade | wing 8b.

  Desirably, the shaft output transmission mechanism of the 2nd blade motor 14b which drives the 2nd up-and-down direction wind direction change blade 8b is built in the 2nd arm part 6b. The shaft output 14b ′ of the second blade motor 14b is connected to a pulley 23 built in the second arm portion 6b. The timing belt 24 and the second vertical direction change in the second arm portion 6b are connected to the timing belt 24. The pulley 22 connected to the shaft of the blade 8b is arranged, and the second vertical air direction changing blade 8b can be freely rotated 9 via the pulleys 22, 23 and the timing belt 24. The boss 21 of one second arm portion 6b is supported by a hole disposed in the main body of the air conditioner 1, and the boss of the other second arm portion 6b is the second arm portion motor 13b. It is connected to the output shaft 13b 'and can be rotated 7 freely.

  According to this desirable configuration, the second blade motor 14b can be disposed on the main body side of the air conditioner 1, and the weight of the second arm portion 6b is reduced, whereby the second arm portion. Compared with the case where the second blade motor is disposed at the tip of 6b, the torque of the second arm motor 13b is reduced with respect to the rotation of the second arm portion 6b. The motor 13b can be downsized.

  The shaft output transmission mechanism of the second blade motor 13b that drives the second vertical wind direction changing blade 8b is the same even if a driving force transmission mechanism using a combination of gears is used instead of a timing belt and a pulley. The effect of can be obtained.

  A drive device having the same structure as the drive device for the second up / down direction wind direction change blade 8b is provided separately for the first up / down direction wind direction change blade 8a, and the first arm portion 8a has the first arm portion 8a. The arm motor 6a can be driven independently of the second arm portion 8b, and the first vertical wind direction changing blade 8a is driven by the first blade motor 14a. The direction wind direction changing blade 8b can be driven independently.

  Next, FIGS. 3A to 3C show the airflow control operation during heating of the two vertical airflow direction changing blades by the airflow direction control device of the present embodiment. FIGS. 5A to 5C are diagrams showing the air flow in the room in each of these airflow control operations.

  In FIG. 3 (a), the end on the first arm portion 6a side of the first vertical wind direction change blade 8a is brought close to the upper surface of the second vertical wind direction change blade 8b, and the position of this close portion is also shown. Is moved slightly closer to the upper end than the center of the upper end and the lower end of the air outlet 5, so that the air volume distribution of the air blow 15 a passing through the upper surface side of the first vertical wind direction changing blade 8 a is about 30%. The air volume distribution of the blown air 15b passing through the lower surface side of the up / down direction wind direction changing blade 8b can be about 70%.

  Further, the vertical wind direction of the first vertical wind direction changing blade 8a is adjusted by the first blade motor 14a, and the vertical wind direction of the second vertical wind direction changing blade 8b is adjusted by the second blade motor 14b. Accordingly, as shown in FIG. 5 (a) -1, the blown air 15b passing through the lower surface side of the second up-and-down direction wind direction changing blade 8b is blown downward and directly heated to the resident near the center of the room. While blowing the foot, the blowing air 15a passing through the upper surface side of the first up-and-down direction wind direction changing blade 8a is blown out in a substantially horizontal direction and is applied to the wall where the air conditioner 1 is installed from the ceiling. By circulating the entire room along the facing wall, the room including the ceiling and wall surface can be warmed more efficiently, and more energy efficient heating can be realized.

  In FIG. 3A, when the second vertical wind direction changing blade 8b is moved to the position 8b 'shown by the broken line, the vertical wind direction is adjusted by the second blade motor 14b to the second vertical direction. By adjusting the direction wind direction changing blade 8b slightly upward, the blowing wind 15 '(shown by a broken line) is, for example, a residence slightly further from the vicinity of the center of the living room, as shown in FIG. 5 (a) -2. The person's feet can be warmed. Therefore, even if a resident's whereabouts change, it can always be adjusted to the optimal up-down direction according to a resident's request, and a more comfortable warm air can be delivered to a resident. If there is a means for detecting the position of a person with a sensor or the like, it is possible to automatically adjust the wind direction to the optimum vertical direction.

  In FIG.3 (b), while making the edge part by the side of the 1st arm part 6a of the 1st up-down direction wind direction change blade | wing 8a close to the upper surface of the 2nd up-down direction wind direction change blade | wing 8b, the position of this adjacent part Is moved slightly closer to the lower end than the center of the upper end and the lower end of the blowout port 5, so that the air volume distribution of the blown air 15 a passing through the upper surface side of the first vertical wind direction changing blade 8 a is about 70%, The air volume distribution of the blown air 15b passing through the lower surface side of the up / down direction wind direction changing blade 8b can be about 30%. In this control operation example, contrary to the control operation example of FIG. 3A, the blowing air from the lower part is distributed less than the blowing air from the upper part of the outlet.

As in these control operation examples, the joint between the first vertical wind direction changing blade 8a and the first arm portion 6a is used as the joint between the second vertical wind direction changing blade 8b and the second arm portion 6b. The air volume distribution between the air blow from the upper part of the air outlet and the air flow from the lower part can be freely changed by moving the position of the close part between the upper end and the lower end of the air outlet. Can do.

  Further, in FIG. 3B, the vertical direction of the first vertical wind direction change blade 8a is set by the first blade motor 14a, and the vertical direction of the second vertical direction change blade 8b is set by the second blade. By adjusting with the motor 14b, as shown in FIG. 5 (b) -1, the blown air 15b passing through the lower surface side of the second vertical airflow direction changing blade 8b is blown downward with a weaker airflow. The airflow 15a passing through the upper surface side of the first up / down direction wind direction changing blade 8a can be warmed while making the occupant near the center of the living room feel the warm air as much as possible. The entire room is circulated along the wall facing the wall where the air conditioner 1 is installed from the ceiling, and the room including the ceiling and walls is warmed more efficiently and saved. It is possible to realize the value of high heating.

  In addition, as shown in FIG. 5B-2, when a resident is present before and after an obstacle 16 such as furniture or furniture such as a sofa or storage shelf placed on the floor in the living room, the second The blowing air 15b passing through the lower surface side of the vertical wind direction changing blade 8b warms the resident's feet in front of the obstacle 16, and the blowing air 15a passing through the upper surface side of the first vertical air direction changing blade 8a is The warm air circulates from the ceiling along the opposite wall of the wall where the air conditioner 1 is installed without being obstructed by the obstacle 16 by being blown out in a substantially horizontal direction. You can also warm the space where you are.

  In this way, in the wind direction control device of the present embodiment, even when the resident is near or when the resident does not like the feeling of warm air flow, the air volume of the blowing air into the room is sufficiently secured and the entire room is While warming up efficiently, the warm air feeling can be weakened and the comfort of heating can be improved. In addition, even when the obstacle 16 that prevents the hot air from reaching the floor is on the floor, the hot air can be delivered not only to the resident in front of the obstacle 16 but also to the resident in the back. It is possible to perform heating that is more efficient and energy-saving while satisfying the heating feeling of the residents.

  In FIG.3 (c), while making the edge part by the side of the 1st arm part 6a of the 1st up-down direction wind direction change blade | wing 8a close to the upper surface of the 2nd up-down direction wind direction change blade | wing 8b, the position of this adjacent part Is moved to the upper end of the blowout port 5, so that the airflow distribution of the blown air passing through the upper surface of the first vertical airflow direction changing blade 8 a is approximately 0% when the airflow of the entire blown air is 100%. The air volume distribution of the blown air 15 passing through the lower surface side of the up / down direction wind direction changing blade 8b can be almost 100%.

  Further, by adjusting the vertical air direction of the second vertical air direction change blade 8b with the second blade motor 14b, all the blown air 5 is blown downward as shown in FIG. Can be concentrated at the feet of the residents near the center of the room. By this air flow control operation, for example, when the room temperature in the room does not reach the set temperature at the start of operation or when entering the room from the cold outdoors, the feet are intensively and rapidly warmed to make it feel faster Can be improved.

  4A to 4C show the airflow control operation during cooling of the two vertical airflow direction changing blades by the airflow direction control device of the present embodiment. FIGS. 6A to 6C are views showing the air flow in the room in each of these airflow control operations.

In Fig.4 (a), while making the edge part of the 1st arm part 6a side of the 1st up-down direction wind direction change blade | wing 8a close to the upper surface of the 2nd up-down direction wind direction change blade | wing 8b, the position of this adjacent part Is moved slightly closer to the upper end than the center of the upper end and the lower end of the air outlet 5, so that the air volume distribution of the air blow 15 a passing through the upper surface side of the first vertical wind direction changing blade 8 a is about 30%. The air volume distribution of the blown air 15b passing through the lower surface side of the up / down direction wind direction changing blade 8b can be about 70%.

  Further, the vertical wind direction of the first vertical wind direction changing blade 8a is adjusted by the first blade motor 14a, and the vertical wind direction of the second vertical wind direction changing blade 8b is adjusted by the second blade motor 14b. 6 (a) -1, the blowing air 15b passing through the lower surface side of the second up / down air direction changing blade 8b is blown downward and is located near the center of the room. A cool wind is directly applied to a resident who likes it, a hot resident, a resident who feels hot after taking a bath or exercising, etc., to enhance the cool feeling, and the first vertical wind direction change blade 8a The blown air 15a passing through the upper surface is blown horizontally or slightly upward and circulates throughout the living room along the opposite wall of the wall where the air conditioner 1 is installed. Inside the room It is possible to realize a cooling excellent in energy saving property than can be cooled efficiently.

  In FIG. 4A, when the second vertical wind direction changing blade 8b is moved to the position 8b 'shown by the broken line, the vertical wind direction is adjusted by the first blade motor 14a to the second vertical direction. By adjusting the direction wind direction changing blade 8b slightly upward, the blowing wind 15 ′ (shown by a broken line) is, for example, a resident slightly closer to the center of the room as shown in FIG. 6 (a) -2. You can direct cool air to 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 a more comfortable cold wind can be delivered to a resident. If there is a means for detecting the position of a person with a sensor or the like, it is possible to automatically adjust the wind direction to the optimum vertical direction.

  In FIG.4 (b), while making the edge part by the side of the 1st arm part 6a of the 1st up-down direction wind direction change blade | wing 8a close to the upper surface of the 2nd up-down direction wind direction change blade | wing 8b, the position of this adjacent part Is moved slightly closer to the lower end than the center of the upper end and the lower end of the blowout port 5, so that the air volume distribution of the blown air 15 a passing through the upper surface side of the first vertical wind direction changing blade 8 a is about 70%, The air volume distribution of the blown air 15b passing through the lower surface side of the up / down direction wind direction changing blade 8b can be about 30%. In this control operation example, in contrast to the control operation example of FIG. 4A, the blowing air from the lower part is distributed less than the blowing air from the upper part of the blowing outlet.

  As a result, as shown in FIG. 6B, the blown air 15b passing through the lower surface side of the second vertical airflow direction changing blade 8b is blown downward with a weaker air volume than in the case of FIG. 6A. Directly apply weak cold air to residents who are near the center of the room, for example, those who prefer a weaker airflow, those who are slightly hot, or those who feel a little hot after light work, etc. The blowing air 15a which gives a moderate cool feeling and passes through the upper surface side of the first up-and-down air direction changing blade 8a is blown out in a substantially horizontal direction and faces the wall where the air conditioner 1 is installed from the ceiling. By circulating the entire room along the wall, it is possible to cool the room including the ceiling and wall surface more efficiently and to simultaneously achieve cooling with higher energy savings.

  As in these control operation examples, the joint between the first vertical wind direction changing blade 8a and the first arm portion 6a is used as the joint between the second vertical wind direction changing blade 8b and the second arm portion 6b. The air volume distribution between the air blow from the upper part of the air outlet and the air flow from the lower part can be freely changed by moving the position of the close part between the upper end and the lower end of the air outlet. Can do.

As described above, the wind direction control device of the present embodiment can freely adjust the feeling of cool air to the occupant, thereby providing a comfortable cooling environment more suitable for each resident, and at the same time, blowing air blown into the living room. Excellent energy saving can be realized by securing a sufficient air volume and efficiently cooling the entire room.

  In FIG.4 (c), while making the edge part of the 1st arm part 6a side of the 1st up-down direction wind direction change blade | wing 8a close to the upper surface of the 2nd up-down direction wind direction change blade | wing 8b, the position of this adjacent part Is moved to the lower end of the blowout port 5, and the air volume distribution of the blown air passing through the upper surface side of the first vertical airflow direction changing blade 8 a is almost 100% when the airflow of the whole blown air is 100%. The air volume distribution of the blown air 15 passing through the lower surface side of the up / down direction wind direction change blades 8b can be almost 0%. Further, by adjusting the vertical air direction of the second vertical air direction changing blade 8b with the second blade motor 14b, all of the blowing air 5 is blown out horizontally or upward as shown in FIG. 6C. It is possible to prevent the cool air from hitting the residents near the center of the room at all.

  This air flow control operation makes it easier to feel cold because the resident is sitting or sleeping for a long time and the metabolic rate decreases and it is easy to feel cold in women and limbs. In the case of a resident or the like who does not like to hit directly, it is possible to eliminate the feeling of cold air by not directly hitting the cold air, and to improve the feeling of comfort during cooling.

  7 shows that the first up-down direction wind direction changing blade 8a and the second up-down direction wind direction changing blade 8b are driven and stored in the outlet 5 when the operation of the air conditioner of the present embodiment is stopped. The cross-sectional view of the air conditioner 1 is shown, and the first vertical wind direction change blade 8a and the second vertical wind direction change blade 8b do not protrude or protrude from the main body of the air conditioner 1 in a compact manner. It can be stored in a container and can have an appearance with excellent design.
