Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner having an improved conditioned air blowing structure.

In conventional air conditioners, the air volume above the air outlet and the air volume below the air outlet are set to be almost the same, and no particular consideration is given to the difference in air volume. Therefore, during heating, when the blowout temperature rises and the temperature difference with the indoor air becomes large, the blowout airflow on the upper side of the outlet and the airflow on the lower side rise in parallel, and the reaching distance is shortened. As a result, the temperature distribution in the room worsens, resulting in an uncomfortable feeling of being hotter at the head and colder at the feet. Figure 8 shows the state of the room at this time, and the airflow above the outlet (arrow P) and the airflow below it (arrow P') rise in the same way, resulting in a high temperature area in the upper part of the room. It can be seen that a wide low-temperature area has formed in the lower part of the room, creating an uncomfortable situation.

The present invention improves the shortcoming of the above-mentioned conventional methods, which is the insufficient reach of the airflow when the difference between the airflow temperature and the room temperature becomes large, and improves the indoor temperature distribution to provide highly comfortable air conditioning. The purpose is to

Therefore, the present invention includes a heat exchanger, a blower, and a
A blowout temperature detection means having a blowout outlet on the front surface of the main body, a blowout temperature detection means for detecting the blowout air temperature, a blowout air volume control means for controlling the distribution of the air volume passing through the blowout outlet, and when the blowout temperature detection means detects a constant temperature. A drive means for operating the blowout air volume control means is provided. With this configuration, the blowout temperature can be detected,
Based on the value, the driving means drives the blowout air volume control means, and has the effect of providing an airflow distribution at the blower outlet, increasing the reach of the blowing airflow, and enhancing the effect of stirring the air in the room. Hereinafter, an embodiment of the present invention will be described in which a vertically elongated air outlet is provided, and a plurality of dampers are provided below the air outlet as means for controlling the amount of air blown out.

1 is the air conditioner main body, inside which is a heat exchanger 2,
It has a blower 3. Further, a damper 4 is provided at approximately the lower half of the air outlet 5, and a motor 6 is attached as a device for driving the damper 4.

Further, the motor 6 is rotated via a relay 8 in response to a signal from a blowout temperature detector 7.

When heating is started in the above configuration, the suction port 9
The indoor air sucked in from the inside is heated by the heat exchanger 2 and is blown out from the outlet 5 as warm air.
At this time, when the blowout temperature detector 7 detects that the blowout temperature has exceeded a certain value and sends a signal to the relay 8, the switch 10 of the motor 6 is turned on, the motor 6 rotates, and the damper 4 is driven. The volume of the blown air below the outlet 5 is controlled by the damper 4, resulting in an air volume distribution as shown by the solid line in FIG. In the figure, the conventional blowout air volume distribution is shown by a broken line, but at this time,
The overall air volume of this embodiment and the conventional example are equal. (However, when the air volume is controlled by the damper 4, it is necessary to increase the rotation speed of the blower.) However, since the air flow above the air outlet 5 in this embodiment has a large air volume, the reaching distance is longer than in the conventional example. Long, outlet 5
The lower airflow, which tends to rise with a small air volume, also gets mixed in with the indoor air.

Therefore, in this embodiment, even if the overall air volume is the same as the conventional one, the reach of the discharged airflow is increased, so the discharged airflows P, P' on the upper and lower sides of the outlet 5 are increased while maintaining the heating capacity. flows out as shown in Figure 7, improving the temperature distribution in the room, eliminating uncomfortable high and low temperatures, and providing a comfortable heating effect. And this method is especially useful after the room temperature reaches the set value and stabilizes.
This is extremely effective when operating at low airflow and wanting to maintain a good indoor temperature distribution.

Although this embodiment has been described with respect to an air conditioner having a vertically elongated air outlet, similar effects can be obtained in an air conditioner having a square or horizontally elongated air outlet.

As is clear from the above description, the air conditioner of the present invention includes an air outlet provided on the front surface of the main body provided with a heat exchanger and a blower, an air outlet temperature detection means for detecting the temperature of the air blown out, and an air conditioner provided at the air outlet. and a drive means for operating the blowout air volume control means when the blowout temperature detection means detects a constant temperature. Based on the temperature value, the blowout airflow control means is used to create an airflow distribution in the blowout airflow, thereby increasing the reach of the blowout airflow, enhancing the effect of stirring with the indoor air, and improving the indoor temperature distribution. . In particular, when the air flow rate is small for heating and the air temperature rises, if the air flow rate above the outlet is increased and the air flow rate below the outlet is reduced,
Compared to when the air is blown out uniformly, the reach distance is significantly increased, and the effect of improving indoor temperature distribution is remarkable.
