2. Description of the Related Art As a device for controlling the temperature in a room, an air conditioner for heating and cooling is installed in a building or the like, and there is a general household equipped with so-called central heating. Even so, air conditioning equipment is installed in each room to obtain a comfortable room temperature.

[0003] No matter what kind of cooling and heating equipment is used, the temperature deviation of the room occurs because the temperature of the air is changed by the equipment. That is, the relatively cool air is heavier than the warm air and falls down, the warm air rises up, but the warm air that rises cools down and the original cold air that is relatively warm rises. The convection that goes up occurs.

However, such natural convection alone does not actually equalize the room air temperature, so that the area around the feet does not become warm during heating, while only the feet become cold during cooling. Inconvenience occurs.

In such a case, usually, the strength of heating or cooling is further increased, but if the temperature in the room is averaged, it is possible to sufficiently utilize the heating or cooling without increasing the strength of heating or cooling. You can

Therefore, conventionally, it is recommended to install a fan that promotes the circulation of air. This fan includes a sirocco fan installed at the Kamoi or the contact point between the ceiling and the wall, and a ceiling fan installed on the ceiling.

[0007]

However, since these fans are installed near the ceiling in any case, warm air near the ceiling can be moved downward, but even cold air near the floor can be moved. However, it has not reached the point where it is moved to make the temperature uniform. Therefore, extra heating energy and cooling energy are required, and improvement has been desired from the viewpoint of energy saving.

The present invention has been made in view of such a background, and an object thereof is to be attached to an indoor unit of an air conditioner and used to efficiently exchange heat energy to control the indoor temperature. An object of the present invention is to provide an indoor air circulation device that can achieve uniformity and promote energy saving, and an air conditioner including the device.

[0009]

Although it may be directly connected to the air intake chamber of the indoor unit, the air intake opening of the indoor unit is provided with a cover that covers the entire surface or a part of the air intake opening and is detachably attached. It may be attached to the indoor unit via. Furthermore, this indoor air circulation device can be configured integrally with the indoor unit of the air conditioner.

[0011]

For example, during heating in winter, by connecting the tubular body to the air intake chamber of the indoor unit and operating the air conditioner, cold air near the floor of the room is passed through the tubular unit through the tubular unit. Is sucked in, heated by the heat exchanger, and then discharged from the air outlet of the indoor unit.

On the other hand, during the cooling in the summer, the cold air staying near the floor is sucked into the indoor unit through the cylinder, passed through the heat exchanger, and then discharged from the air outlet of the indoor unit. To be done.

In any case, the cold air and the warm air are efficiently stirred, and the temperature in the room can be made uniform. At that time, since the indoor unit of the air conditioner installed indoors is used, it is very economical. Further, by integrally combining this indoor air circulation device with an indoor unit, an air conditioner with good air circulation efficiency can be obtained.
