Description

[Detailed description of the invention] [Field of industrial application] This invention relates to an air conditioner, in particular, the interior is divided into an indoor side and an outdoor side by a partition plate, an evaporator is placed on the indoor side, and a condenser and a condenser are placed on the outdoor side. This invention relates to an integrated (window type) air conditioner in which compressors are respectively arranged, and to improvements in the drain tray of the evaporator and its drainage mechanism.

[Conventional technology]

An integrated air conditioner is divided into an indoor side and an outdoor side by a partition plate, and an evaporator is placed on the indoor side, and a compressor and a condenser are placed on the outdoor side to form a refrigeration cycle. The condenser is cooled by a propeller fan rotated by a fan motor, and the indoor air is circulated through the evaporator by a Sirotskov fan housed in the casing on the indoor side to cool the room.

Also, during cooling operation of this type of air conditioner, the moisture contained in the circulating air is removed by condensation in the evaporator, and the drain generated by this condensation is
The water is collected in a drain tray provided at the bottom of the evaporator, guided to the outside through a drain pipe provided in the drain tray, and then discharged to the outside of the air conditioner through a drain pipe provided outside the room. Note that such an air conditioner is disclosed in, for example, Japanese Utility Model Publication No. 17256/1983.

[Problem that the invention attempts to solve]

In conventional air conditioners such as those mentioned above, in order to discharge the drain in the drain tray to the outdoor side, a long drainage pipe that penetrates the partition plate and reaches the outdoor side from the drain tray is formed integrally with the drain tray. In some cases, a drainage pipe with a separate structure was connected to the drain tray. For this reason, if the drain pipe has an integral structure with the drain tray, and the drain tray is made of styrofoam, etc., the drain pipe is likely to break, making handling and management troublesome, and the workability of assembling the tray is poor. There's a problem. In addition, when the drain pipe is constructed separately from the drain tray, it takes time and effort to connect the two, resulting in high costs and the problem that positioning the drain tray becomes troublesome.

[Purpose of invention]

This invention was made in order to solve the above-mentioned conventional problems.It does not require a pipe etc. to discharge the drain to the outdoor side of the drain tray, and it also simplifies the assembly work of the drain tray. An object of the present invention is to provide an air conditioner that is easy to position and hold.

[Means for solving problems]

In the air conditioner according to this invention, at least one drainage channel is formed in a dead space portion of a fan casing attached to a partition plate that divides the inside of the main body into an indoor side and an outdoor side so as to communicate between the indoor side and the outdoor side. The drainage port of the drain tray is fitted into this drainage channel, so that the drain in the drain tray is drained to the outside of the room.

[Effect]

In this invention, the drain channel formed in the fan casing becomes a path for discharging the drain in the drain tray to the outdoor side, and the two can be connected simply by fitting the drain port of the drain tray into the drain channel.

1 is formed, and the drain port 19 of the drain tray 18 is fitted into the end of the drain channel 21 on the notch 20 side. The bottom surface 21a of the drain channel 21 is formed lower than the protruding level of the drain port 19, as shown in FIG. 4, and an edge 22 for drain overflow is formed at the outdoor opening edge of the drain channel 21.

Reference numeral 23 denotes a front panel that covers the front surface of the air conditioner main body, and this front panel 23 includes a suction port 23a facing the evaporator 5 and a blowout hole located above the suction port 23a and communicating with the blowout guide frame 7a. 23b, respectively.

In the air conditioner of this embodiment configured as described above, when the air conditioner is in the cooling operation mode, when the Sirotskov fan 14 is rotated by starting the fan motor 12, the indoor air is sucked by its suction action. The air is sucked in through the suction port 23a of the front panel 23 and cooled while passing through the evaporator 5. This cooled air is sucked into the wind tunnel 16 of the fan casing 15 from the bell mouth 6, and is further discharged by the discharge action of the Sirotskov fan 14. The air is blown into the room from the circulation air path 17 through the blow-off hole 23b and the blow-off guide frame 7a, thereby cooling the room.

Moisture contained in the air passing through the evaporator 5 is condensed in the evaporator 5, and the resulting drain is collected in the drain tray 18, and is discharged from the tip of the drain port 19 as indicated by the arrow in FIG.
