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 difference in air temperature between the upper side of the outlet and the lower side of the outlet is not particularly taken into consideration, and the temperatures are almost the same, so during heating, the airflow above the outlet and that below the outlet rise in the same way. However, the reach distance is short, and the indoor air cannot be sufficiently stirred, resulting in poor indoor temperature distribution, resulting in the discomfort of feeling hotter at the head and colder at the feet. In other words, Figure 6 shows the state of the indoor temperature distribution in a conventional air conditioner with a vertically elongated outlet, where both the airflow above the outlet and that below the outlet rise in parallel as shown by the arrows. As a result, the high temperature region in the upper part of the room and the low temperature region in the lower part of the room are wide, creating an uncomfortable situation.

The object of the present invention is to improve the above-mentioned conventional drawback of insufficient reach of the blown air flow, improve the indoor temperature distribution, and perform air conditioning with high comfort.

That is, the main body has a heat exchanger, a blower auxiliary heat exchanger, and an outlet on the front surface of the main body, and by providing the auxiliary heat exchanger unevenly below the outlet, the air at the outlet during heating can be heated. The blowout temperature is distributed to be low at the upper side of the outlet and higher at the lower side, thereby increasing the reach of the blowout airflow. Hereinafter, an embodiment of the present invention in which a vertically elongated outlet is provided and an auxiliary heater is provided as an auxiliary heat exchanger unevenly distributed below the outlet will be described with reference to FIGS. 1 to 5. .

1 is the air conditioner main body, inside which is a heat exchanger 2,
It has a blower 3. In addition, the auxiliary heater 4 is connected to the air outlet 5.
It is provided close to the heat exchanger 2 at a position below the heat exchanger 2 .

When heating is started in the above configuration, the suction port 6
Indoor air sucked in is heated by a heat exchanger 2 and an auxiliary heater 4, and is blown out from an outlet 5 as warm air. However, at this time, the airflow from above the air outlet 5 passes only through the heat exchanger 2, and that from the lower side of the air outlet 5 passes through both the heat exchanger 2 and the auxiliary heater 4. Figure 4 shows the outlet temperature distribution at the outlet 5 as a solid line. As can be seen from the figure, the temperature of the air flowing from the upper side of the outlet 5 is lower than the overall average outlet temperature; taller than. Here, the conventional blowout temperature distribution is shown by a broken line, and at this time, the heating capacities of this embodiment and the conventional example are equal. However, since the temperature difference between the air flow above the air outlet 5 and the indoor air in this embodiment is smaller than that of the conventional air flow, it is difficult to rise and has a long reach.
On the other hand, the airflow below the outlet 5 tries to rise due to its high temperature, but cannot rise because it is blocked by the airflow above the outlet 5, and is mixed with the indoor air.

Therefore, in this embodiment, while maintaining the same heating capacity as the conventional one, it is possible to increase the reach of the blown airflow, so as shown in Fig. 5, the temperature distribution in the room is improved, and uncomfortable high and low temperatures are avoided. is eliminated, and a comfortable heating effect can be obtained.

Furthermore, this embodiment is a heat pump type air conditioner, and since the auxiliary heater for heating has been used in the past, there is no increase in cost simply by changing its mounting position.

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 has a heat exchanger, a blower, an auxiliary heat exchanger in the main body, and an outlet on the front of the main body, and the air temperature at the outlet during heating is Since the auxiliary heat source is unevenly distributed below the outlet so that it is distributed low above the outlet and high below the outlet, the reach of the outlet air can be extended, and the indoor air It sufficiently stirs the air and greatly improves the temperature distribution in the room, making it extremely effective in creating a comfortable air-conditioned space.
