[0001]

BACKGROUND OF THE INVENTION The present invention is particularly suitable for heating operation.
The present invention relates to an air conditioner capable of maintaining a blown wind direction as downward as possible.

[0002]

2. Description of the Related Art A conventional air conditioner, for example, as shown in FIG. 3, has an air passage connecting a suction port 2 provided on the front surface of a main body 1 and / or an upper portion with an air outlet 5 formed by a blower casing. A heat exchanger 3 and a blower fan 4 are provided, and the air that has been heat-exchanged by the heat exchanger 3 is sent to the blower outlet 5 by the blower fan 4, and a vertical wind direction plate pivotally supported by the blower outlet 5 is provided. 6, the wind direction in the vertical direction is deflected. With the above configuration, during the heating operation, by rotating the vertical airflow direction plate 6 so that the air outlet 5 is formed downward, warm air is sent toward the feet in the room to perform air conditioning. . However, the outlet 5
When the up-and-down airflow direction plate 6 is rotated so as to be formed downward, the air resistance increases due to the up-down airflow direction plate 6 and the lower ends of the air outlets 5, and it is difficult for warm air to reach the feet of the room. Had a problem.

[0003]

In the present invention, in view of the above-mentioned problems, air which can maintain the blowing direction toward the lower side as much as possible during the heating operation and allows warm air to reach the feet. The purpose is to provide a harmony machine.

[0004]

In order to solve the above-mentioned problems, a heat exchanger, a blower fan, etc. are provided in an air passage connecting a suction port and a blowout port formed in a main body, and the blowout port is vertically moved. In an air conditioner provided with a wind direction plate, an air guide passage for blowing the wind from the blower fan to the lower side of the main body is provided in front of the air outlet, and an openable air guide plate is provided in the air guide passage. It is characterized by Further, a support shaft portion is provided on both sides of the back surface of the baffle plate, and the support shaft portion is rotatably supported on both side walls of the suction port. In addition, the support shaft portion of the baffle plate is formed by an arm that is erected on the back surface of the baffle plate and a support shaft that projects outward from the tip end portion of the arm. Further, the arm and the support shaft are integrally formed with the baffle plate. Further, when the baffle plate is rotated, a rear end of the baffle plate is projected into the air passage. Further, a drive device is provided on the baffle plate. Further, the driving device is a motor.

[0005]

With the above structure, the air conditioner is capable of delivering warm air to the feet without receiving air resistance at the lower end of the air outlet during heating operation.

[0006]

Embodiments of the present invention will now be described in detail with reference to the drawings. In FIGS. 1 (A), (B) and 2, 1 is an indoor unit body of an air conditioner, 2 is a front cover detachably attached to the body 1 and a suction provided on an upper surface of the body 1. A port, 3 is a heat exchanger provided in the main body 1 for exchanging heat with the air sucked from the suction port 2, and 4 is a blower fan provided in an air passage for sending the heat-exchanged air to an outlet described later. , 5 are outlets for blowing air toward the room. Reference numeral 5a denotes an air guide passage provided in front of the air outlet 5 for efficiently ejecting warm air toward the lower side of the main body 1 particularly during heating operation. Reference numeral 6 denotes a vertical wind direction plate rotatably supported by both side walls of the outlet 5. Reference numeral 7 denotes an air guide plate pivotally supported by both side walls of the air guide path 5a so that the air guide path 5a can be opened and closed. 7a is the baffle plate 7
The arms 7b integrally projecting on both sides of the back surface of the same are support shafts integrally projecting outward at the tip of the arm. Since the arm 7a and the support shaft 7b are integrally formed with the baffle plate 7, the dimension and shape are accurately finished and the arm 7a and the support shaft 7b are pivotally supported so as to be smoothly rotated on both side walls of the baffle path 5a. Thus, the air guide path 5a can be opened and closed accurately, and the configuration is advantageous in terms of cost. As shown in FIGS. 1 (B) and 2, the baffle plate 7 opens the baffle path 5a by rotating around the support shaft 7b, especially at the time of heating operation, and the rear end thereof is the same. By projecting to the front upper part of the air guide path 5a, the projecting portion a guides the warm air to the same air guide path 5a so that the warm air can be efficiently delivered to the lower side of the main body 1. Also, the baffle plate 7
During the cooling operation, as shown by the solid line in FIG. 1 (A) and the broken line in FIG.
By closing 5a, the vertical airflow direction plate 6 rotated to a substantially horizontal position sends out cool air in a substantially horizontal direction so that air can be conditioned in the room. Reference numeral 8 denotes a drive device which is linked to the support shaft 7b of the baffle plate 7 and is a motor for driving the support shaft 7b. Since the drive device 8 is a motor, the air guide plate 7 is rotated to accurately open the air guide path 5a as shown in FIG. The projecting portion a by the rear end smoothly guides the warm air to the air guide passage 5a,
It has a structure that allows warm air to reach the feet of the room from 5a for air conditioning.

With the above structure, the heating operation shown in FIG.
(B), as shown in FIG. 2, the vertical wind direction plate 6 is rotated to a substantially vertical position, and the drive device 8 causes the support shaft 7b to rotate.
The air guide plate 7 is rotated by driving the air guide plate 7 so that the rear end of the air guide plate 7 is projected to the upper front part of the air guide path 5a, and warm air is directed to the air guide path 5a by the protruding portion a. The air conditioner guides the air and sends it downward from the air guide passage 5a and the air outlet 5 so that it can reach the feet sufficiently and becomes an air conditioner. During the cooling operation, the solid line shown in FIG.
As indicated by the broken line, the vertical wind direction plate 6 is rotated to a substantially horizontal position, and the wind guide path 5a is closed by the wind guide plate 7, so that the vertical wind direction plate 6 allows the cool air to flow in the horizontal direction in the room. It becomes an air conditioner that can be air-conditioned by deflecting and sending out.

[0008]

As described above, according to the present invention, during heating operation, air resistance is not applied to the lower end of the air outlet,
The air conditioner is capable of sufficiently delivering warm air to the feet and capable of deflecting and delivering the cool air in the horizontal direction during the cooling operation.
