Description

[Detailed Description of the Invention] The present invention relates to a drain drainage device for an air conditioner that does not require attachment or detachment of a drain hose to drain the drain from the air conditioner to the outside, and that eliminates the need for an extension to the outside.

Conventionally, in an air conditioner of the type that does not extend outside, a drain drainage system is installed at the bottom of the air conditioner main body 1, as shown in Fig. 1, to discharge the drain from the air conditioner to the outside. It was necessary to connect one end of the drain hose 3 to the port 2 and place the other end in a drain receiver 4 provided outdoors.

Not only is it very troublesome to attach and detach such a drain hose, but it is also necessary to store it when the air conditioner is not in operation.

The present invention was devised in view of the drawbacks of the conventional devices as described above, and its purpose is to provide a rotatable drain gutter below the drain outlet, and to attach the drain gutter to the main body of the air conditioner. It can be rotated by an actuating piece between the lower part and the drain receiver installed outside the window, eliminating the complicated operation of attaching and detaching the drain hose from the back of the air conditioner body as in the past. To provide a drain/drainage device for an air conditioner which not only allows the storage of a drain hose but also eliminates the need for storing a drain hose.

Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 2, an outer frame 10 is airtightly attached to the inside of the window frame 9 of the room (see FIG. 4), and a support base 11 is fixed to the lower part of the outer frame 10. An air conditioner 12 is placed on the support stand 11 so as not to protrude from the window.
A drain gutter 13 that drains drain from a drain outlet 8 provided at the bottom of the air conditioner 12
It is configured to be able to pivot in the space between the bottom surface of the main body and the support base 11.

As shown in FIG. 3, the drain gutter 13 consists of a socket 14 rotatably connected to the drain outlet 8 and a gutter section 15 extending a required length from the socket. The gutter part 15 may be a drain pipe, and its required length is the same as that of the drain receiver 16 provided outside the window when the drain of the drain gutter 13 is turned as described later.
The length was chosen to allow for a close-up view.

As described above, the mechanism for rotating the drain gutter 13 includes an operating rod 17 provided on the drain gutter 13 for rotating the drain gutter 13 around the rotatable socket 14. When operated, the drain outlet of the drain gutter 13 is moved in and out of the window from the air conditioner, and when it comes out of the window, it is configured to face the inside of the drain receiver 16.

The operating rod 17 includes an arm portion 18 protruding from the drain gutter 13, a first pivot shaft 19 provided at the base end of the arm portion 18, and fixed to the bottom of the air conditioner 12 or the support base 11. A long hole 20 provided in the arm portion 18, a second pivot shaft 21 fixed to the bottom of the air conditioner 12 or the support base 11, and one end of which is pivoted to the pivot shaft 21 and connected to the front surface of the air conditioner 12. It consists of an actuating piece (lever) 22 that protrudes from the lever, and a pin 23 that is implanted at the other end of the lever 22 and is movable along the elongated hole 20 of the arm portion 18.

The operation of the device of the present invention having the above-mentioned configuration will be described below.

When operating the air conditioner installed inside the room on the window frame 9, the back side of the air conditioner, which had been shut off from the outside air by the closed window, is brought into contact with the atmosphere by opening the window. Before and after the opening of the window, the actuating piece (lever) 22 is moved to the left in FIG. 4. In response to this, the operating rod 17 is moved to the right, and the drain gutter 13 is pivoted from below the air conditioner 12 to the outside, that is, to the drain receiver 16 outside the window. To explain this in detail, by moving the lever 22 to the left, the lever 22
rotates around the second pivot shaft 21. The pin 23 implanted at the rear end of the lever 22 moves within the elongated hole 20 of the arm portion 18 toward the base end of the arm portion 18 while moving the arm portion 18 to the first pivot shaft 19.
Rotate counterclockwise around the center. Therefore,
Since the drain gutter 13 also turns in a counterclockwise direction, the drain outlet of the drain gutter 13 also turns to the drain receptacle 16 outside the window and looks inside.

After the drain drainage is completed in this way or in parallel with this, the air conditioner starts operating. Drain generated during operation of the air conditioner flows from the drain outlet 8 through the drain gutter 13 to the drain receiver 16.
flows down to

When the operation of the air conditioner is stopped as described above, the window is closed to cut off the communication between the air conditioner and the atmosphere. will be moved to. Along with this, the pin 23 at the far end of the actuating piece 22 pivots counterclockwise about the second pivot shaft 21. The rotating pin 23 moves inside the elongated hole 20 into the arm portion 1.
The arm part 18 is rotated in a clockwise direction about the first pivot shaft 19 while sliding from the base end of the arm part 8 to the distal end thereof. Therefore, the drain gutter 13 also pivots clockwise about the first pivot shaft 19 to move its drain port below the air conditioner 12 and store it there.

Afterwards, the window is closed.

As mentioned above, since the drain gutter 13 is rotated so that it appears between the lower part of the air conditioner and the drain receiver 16 outside the window, the drain hose can be attached and detached from the drain outlet as in the conventional case. This eliminates the need for troublesome work, and also eliminates the need to store drain hoses.

In the above embodiment, an example in which the operating rod is configured with a link mechanism has been described, but in order to bias the drain gutter below the main body of the air conditioner, a coil spring is connected to the above-mentioned arm portion and the bottom of the air conditioner 12 or the support stand. The lever 22 may be replaced by a telescopic crank having a built-in coil spring, which may be pivotally connected to the arm portion.

As is clear from the above explanation, according to the present invention, there is no need to attach or detach the drain hose.

The effect can eliminate the danger in case of high installation location.

Therefore, it is no longer necessary to store the drain hose and secure space for it, which is a highly practical effect.
