A conventional air conditioner using a wall-mounted air conditioner has the following problems.
<1> A conventional wall-mounted air conditioner senses the temperature of the sucked air with a sensor and adjusts the temperature. Therefore, it is easy to suck in cool air and warm air immediately after being blown out from the lower part of the air conditioner through the suction port. If the air just after the blowout is sucked in through the air intake, there is a phenomenon (short circuit phenomenon) that the sensor misjudges that the temperature has reached the set temperature even though the cooling air is not sufficiently distributed in the living space. As a result, the air conditioning performance that the air conditioner originally has cannot be fully exhibited.
<2> In particular, when the installation location of the air conditioner is a narrow space such as the ceiling behind the roof, the short circuit phenomenon described above is likely to occur, and the interior of the house could not be sufficiently cooled or heated. .
<3> In the air conditioner disclosed in Patent Document 1, a short-length guide plate is provided in the vicinity of the air outlet of the air conditioner, and a ceiling material or wall is used to supply a part of the air to the room. A small hole must be provided in the material, which not only complicates the structure but also has a low effect of preventing a short circuit phenomenon.

A maintenance space is formed between the horizontal plate and the wall-mounted air conditioner.
In another form of this example, the horizontal plate is a non-porous plate having a transverse width larger than that of a wall-mounted air conditioner and a horizontal plate having a longitudinal width larger than the transverse width of the horizontal plate.
In another form of this example, the entire inner peripheral surface of the ceiling may be surrounded by a chamber.
In another form of the present example, the house has an underfloor space below the living space, and the interior space behind the ceiling and the underfloor space communicate with each other through an outer wall formed with an inner ventilation layer. A blower is additionally placed inside the back of the ceiling where the horizontal plate is placed, and the end of the air supply pipe connected to the blower is guided to the under floor space below the living space, and the interior of the back of the ceiling is passed through the blower. The cooling air or the warm air may be circulated around the living space, and air conditioning may be performed by radiant heat from the floor surface, the wall surface, and the ceiling surface of the living space.
In another form of the present example, the house has a plurality of living spaces in a hierarchical manner, and the space behind the ceiling and the living space on each floor so that the cool air or warm air on the ceiling can flow into the living space on each floor. The space may be communicated via an air supply tube.
In another form of the present example, the house has a roof with roof insulation above the ceiling, and the space in the ceiling and the roof are so that warm air from the ceiling can flow into the roof. You may communicate with the space.

<1> Even if the ceiling is extremely low and the ceiling is extremely low, it is possible to prevent the short circuit phenomenon by simply installing a horizontal plate facing the wall-mounted air conditioner in the space behind the ceiling with the wall-mounted air conditioner. Thus, the original performance of the wall-mounted air conditioner can be exhibited, and the living space can be efficiently cooled or heated using the radiant heat of the cool air or the warm air.
<2> By enclosing the entire inner peripheral surface of the ceiling with a chamber, the efficiency of cooling or heating of the living space using radiant heat becomes higher.
<3> Applicable to various types of houses, for example, when a blower is additionally arranged in the space behind the ceiling, and applied to a house that forms a circulating air flow around the living space, the ceiling is provided via the blower. Cooling or heating can be performed by radiating heat from the floor surface, wall surface, and ceiling surface of the living space by circulating the cool air or warm air inside the back space around the living space.
<4> When applied to a house having a plurality of living spaces hierarchically, the cooling or heating can be performed by flowing the cold air or warm air behind the ceiling into the living space of each floor.
<5> When applied to a house having a hut with roof insulation above the ceiling, not only heating of the living space but also melting of the roof can be performed efficiently.
