Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an air conditioner, and particularly to an indoor unit of an air conditioner that performs air conditioning such as heating, cooling, and dehumidification.

(Prior Art) In recent years, the demand structure for air conditioners has been dominated by dual-purpose heating and cooling types, as electric heat pumps have been evaluated for their safety, economy, and ease of use as heaters. In order to provide comfortable air conditioning with this dual-purpose cooling/heating type,
When cooling, cold air needs to be blown from above, and when heating, warm air needs to be blown from the feet. Therefore, a floor-standing type air conditioner is effective, and a vertical type is preferable because it saves floor space. In addition, in pursuit of comfort during air conditioning, it is necessary to blow out cold air or hot air over a wide range, eliminate the feeling of air flow during heating, or ensure Suita air flow that meets the installation conditions.

This is a side sectional view showing the indoor unit shown in Publication No.-82125, in which 1 is the main body of the indoor unit, 2 is the suction part 3 that sucks indoor air in the center of the front, and the Suita port 4 is in the upper part of the front. In FIG. 7, 5 is a heat exchanger disposed facing the suction part 3, 6 is a front panel provided near the air outlet 4,
A line flow fan 8 is disposed horizontally on the downstream side (back side) of the suction flow of the heat exchanger 5 and is coaxially connected to a driving fan motor (not shown) 7. A plurality of wind direction vanes are rotatably supported at both ends and can change the wind direction; 9 is a casing that forms the outer shell of the indoor unit 1 together with the front panel 2 and forms an air passage; 10 is a heat exchanger 5; It is a drain pan located at the bottom of the
The other embodiment shown in FIG. 8 is an improved version of the above embodiment, and includes an air outlet 11 and a wind direction vane 13 at the bottom. The configuration includes a line flow fan 12.

Next, the operation of the conventional example will be explained using FIGS. 7 and 8.

In FIG. 7, when the line flow fan 6 is rotated by the drive of the fan motor (not shown) 7, indoor air flows into the indoor unit 1 from the suction part 3 of the front panel 2 and passes through the heat exchanger 35. The air is then heat-exchanged and blown into the room again from the air outlet 4, and by repeating this air circulation, indoor air conditioning is performed. Further, the direction of the blowing air is manually or automatically adjusted by the wind direction vane 8 so that it is directed upward during cooling and downward during heating, thereby improving comfort.

Also, in Fig. 8, the upper and lower line flow fans 6.1
2, the main stream of air is blown out from the upper air outlet 4 during cooling and from the lower air outlet 11 during heating, thereby improving comfort especially during heating.

In each figure, the same reference numerals indicate the same or corresponding parts.

Next, the operation of the air conditioner according to this embodiment will be explained in Figures 1 to 5.
This will be explained using figures.

When the indoor unit of the air conditioner of this embodiment is placed in a corner of a room with the suction section 3 facing the diagonal corner of the room as shown in Fig. 5, and cooling or heating is performed, the fan motor Due to the rotation of the line flow fan 19.20 driven by 25.26, the indoor air flows through the front panel 2.
The air is sucked in from the suction part 3 of the air, passes through the heat exchanger 5, undergoes heat exchange, is divided into left and right halves by the casing 9, passes through independent air passages 28 and 29, and is blown into the room again from the air outlet 15.16. Ru. Indoor air conditioning is achieved by repeating this circulation. In this case, as shown in Figure 5, the blown air is blown out in a vertically elongated airflow along the two walls forming the corner where the indoor unit is installed, and enters the room with a certain distance proportional to the blowing speed. It diffuses and homogenizes the indoor environment through convection.

In addition, the vertical wind direction vane 30 arranged at the air outlet 15.16
, 31, the wind direction is changed upward during cooling and downward during heating, thereby improving comfort. Further, if necessary, the left and right wind direction is adjusted by the left and right wind direction vanes 32, 33. For example, when the left and right wind direction vanes 32, 33
By operating continuously, it is possible to condition the air over a wide area with a cool feeling.

Further, by individually controlling the two blowers 23 and 24, operation according to the installation situation is possible.

For example, when installing in a corner of a rectangular room, efficient operation can be achieved by reducing the air volume on the short sides and increasing the air volume on the long sides. Moreover, it is also possible to stop the blower 23 or 24 on one side as necessary.

Furthermore, a rear case 14 that constitutes the outer shell of the indoor unit 1
Since the rear corner 34 of the indoor unit 1 is cut to match the shape direction of the air passage, the indoor unit 1 can be arranged to fit the corner of the room, and the indoor unit shape can also be made vertically long and slim. Since the floor space is small, installation space can be saved and indoor living space can be used effectively.

In addition, as mentioned above, since the Suita wind direction is configured to follow the wall surface, it prevents cold air from entering through the windows on the wall, especially during heating operation, and prevents air from blowing directly into the human body from blowing into non-residential spaces. Helps improve comfort, such as prevention. Furthermore, by independently controlling the two line flow fans, it is possible to achieve energy-saving operation by blowing air suited to the installation conditions and by spot air conditioning, which centrally airs only the areas where it is needed.

Although the fan motors 25 and 26 are connected to the lower side of the line flow fan 19 and 20 in this embodiment, they may be connected to the upper side. Although it is composed of parts, it may be integrated with the back case 14, and in either case, the same functions and effects as in the previous embodiment can be achieved.
