Description

[Detailed Description of the Invention] This invention relates to an air conditioner, and particularly to a dew prevention device.

This invention will be explained in detail below with reference to embodiments shown in FIGS. 1 and 2.

1 is an air conditioner, and 2 is the bottom base of this main body, which is formed into a box shape. 3 is a back panel with a U-shaped cross section that is fixed to the inner wall of this base; 4
5 is a suction grill, 5 is an air outlet, 6 is a heat exchanger, 7 is a blower such as a single-intake Sirotskov fan, 8 is a casing, 9 is a back plate of this casing, and air spaces 10 are provided at both side bends of the back panel 3. It is installed to form a 11 is a drain pan, and 12 is a bent portion, which is formed at the lower end of the casing back plate 9 so as to face the drain pan 11 side. Reference numeral 13 denotes ventilation holes, and a plurality of openings are formed in rows at both ends of the back panel 3, respectively. Reference numeral 14 denotes an air circulation hole, which is bored in the lower part of the casing back plate 9, and forms an outside air ventilation path 15 together with the ventilation hole 13 of the back panel 3. 16 is the ceiling panel,
17 is a baffle plate.

The dew formation prevention device configured in this way has the ventilation holes 13, the air layer 10, and the air circulation holes 14 during cooling operation.
Outside air (indoor) air is sucked in through the outside air ventilation path 15 formed by the casing back plate 9 which is cooled because high temperature air passes through the air layer 10 at this time.
This further prevents heat conduction to the back panel 3. Further, dew adhering to the back plate 9 is collected into a drain pan 11. Moreover, the air sucked into the main body from the outside air ventilation path 15 passes through the heat exchange air 4, mixes with the cooled air, and is blown out forward from the outlet 5.

This invention is constructed as described above, and includes a back panel, a base, a casing back plate, a drain pan, and an air guide plate.The casing back plate and the back panel form an air layer, and the lower part of the casing back plate Since air circulation holes are formed in the back panel and ventilation holes are formed in the back panel, the outside air flow passage prevents heat transfer to the back panel and reliably prevents dew droplets from adhering to the back panel. Furthermore, the air layer 10 has the effect of reducing the depth of the main body because it has only the minimum size that allows air to flow.
