Abstract

PURPOSE:To uniformize the room temperature distribution and consequently improve the comfortness during heating by a method wherein an auxiliary heat source is provided by drawing near to the lower side of a blowoff port so as to get higher blowoff temperature at the lower side than at the upper side of the blowoff port. CONSTITUTION:During heating, the air sucked from a suction port 6 is heated by a heat exchanger 4 and an auxiliary heat source heater 4 and blown-off from a blowoff port. In this case, because the auxiliry heater 4 is located at the lower side of the suction port 6 and consequently tha air in the upper side of the suction port 6 is not heated by the auxiliary heater 4, the air temperatures at the blowoff port are turned to be low at the upper side and high at the lower side, resulting in enlarging the throw of the upper side air due to its diffculty of ascend and in suppressing the ascending tendency of the lower side air from above and consequently in accelerating the mixing of the upper and lower airs. Accordingly, the room air temperature distribution can be uniformized and the comfortness improved.

Description

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

Conventional air conditioners do not take into account the difference in air temperature between the upper side of the outlet and the lower side of the outlet, and the temperature is almost the same, so during heating, the airflow above the outlet and the airflow below it rises as well. However, the reaching distance is short and there is not sufficient mixing with the indoor air, resulting in poor indoor temperature distribution and the head being hotter.
This has the disadvantage that the feet feel cold.

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 area at the top of the room and the low temperature area at the bottom 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, by having a heat exchanger, a blower auxiliary heat exchanger, and an outlet on the front of the main body, and providing the auxiliary heat exchanger unevenly below the outlet, the outlet temperature at the outlet during heating can be adjusted. is distributed low above the outlet and high below the outlet, thereby increasing the reach of the outlet airflow.

Hereinafter, an embodiment of the present invention in which a vertically elongated air outlet is provided and an auxiliary heater is provided unevenly below the air outlet as an auxiliary heat exchanger will be described with reference to FIGS. 1 to 6. .

1 is the main body of the air conditioner, with a heat exchanger 2 and a blower 3 inside.
has. Further, an auxiliary heater 4 is provided at a position below the air outlet 6 and close to the heat exchanger 2 .

When heating is started in the above configuration, indoor air sucked in through the suction port 6 is heated by the heat exchanger 2 and the auxiliary heater 4, and is blown out from the blowout port 6 as warm air. However, at this time, the airflow from the upper side of the Suita outlet 5 passes only through the heat exchanger 2, and the airflow from the lower side of the air outlet 6 passes through the heat exchanger 2.
and auxiliary peak 40. Figure 4 shows the outlet temperature distribution at the outlet 6 as a solid line, and as can be seen from the figure, the temperature of the air flowing from the upper side of the outlet 6 is lower than the overall average Suita temperature, and conversely, the temperature at the lower side is lower than the overall average Suita temperature. is higher. 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 6 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 6 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 outlet airflow, so as shown in Fig. 6, the temperature distribution in the room is improved, and uncomfortable high and low temperatures are eliminated. This eliminates the problem and provides a comfortable heating effect.

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, and an outlet on the front of the main unit in one body, and the outlet 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.
