A vertical portion 5a, a rear inclined portion 5b formed by bending an upper end of the vertical portion 5a and inclining rearward, and an upper end of the rear inclined portion 5b A heat exchanger comprising a downwardly inclined portion 5c bent and inclined downward, 6 is a blower fan, and 7 is an air purifier.

Reference numeral 8 is provided at the bent portion a of the rear inclined portion 5b and the downward inclined portion 5c, and shields the bent portion a so that the suction air sucked from the second suction port 3B does not pass through. Reference numeral 1 denotes a shielding plate, and 9 denotes a second shielding plate provided on the ceiling side of the base 1 in order to shield the suction air from flowing in the front-rear direction in the space above the shielding plate 8. An opening / closing type air guide plate rotatably supported by a suction panel 2a constituting the opening 3B. The opening / closing type air guide plate 10 conceals the suction port 3B in a first state and sucks the same in a second state. The mouth 3B is configured to be opened, while the outside of the first suction port 3A is configured to conceal the suction port 3A in a first state and to be configured to open the suction port 3A in a second state. Retractable air guide plate 11

A suction port 3A is provided, and among the vertical bar 3a and the horizontal bar 3b provided in the suction port 3A as shown in FIG. It is characterized by being formed so as to be vertical.

Another feature is that, as described above, the openable / closable air guide plates 11 are provided on the upper and lower sides of the suction port 3A to conceal the suction port 3A in the first state and the second state. In this case, the suction port 3A is opened, and at the time of the opening, the openable / closable air guide plate 11 stands substantially vertically.

The present invention is characterized in that the second shielding plate 9 is provided between the ceiling of the base 1 and the first shielding plate 8. Although a thin elastic material having a thickness of about 1 mm is used for the second shielding plate 9, the present invention is not limited to this. For example, a cloth may be used.

With the above-described structure, the indoor air is guided to the suction port 3A by the action of the openable / closable baffle plate 11 standing substantially vertically, and the horizontal rail 3b provided in the suction port 3A is provided. By the action, the airflow toward the lower inclined portion 5c of the heat exchanger 5 is rectified, and the air flow can be made to proceed substantially evenly with respect to the lower inclined portion 5c, thereby increasing the heat exchange efficiency of the lower inclined portion 5c to the vertical portion 5a. And it can be improved to the same level as the rear inclined portion 5b or more.
