Description

[Detailed Description of the Invention] The present invention relates to an improvement of a conventional integrated air conditioner, and aims to simplify the structure and improve performance.

An all-in-one air conditioner has a conventional underframe with a partition plate on the board that separates the indoor and outdoor areas, and can be inserted into and pulled out of an outer box with one side open. In order to close the gap between
A sealing plate with an L-shaped cross section was fixed to the inner surface of the iron outer box by spot welding or the like along the inner partition plate. However, in order to seal between the indoor and outdoor sides by applying the sealing plate on the inner surface of the outer box to the partition plate of the underframe inserted into the outer box, the sealing plate must be fixed to the outer box in the correct position. This increases the number of manufacturing steps and makes the cost extremely expensive. Furthermore, since it is almost impossible to attach the seal plate completely along the complicatedly curved partition plate, incomplete sealing between the indoor side and the outdoor side inevitably occurs.
Therefore, there are major problems such as cold air from inside the room leaking to the outside through this part, resulting in a decrease in performance, and noise from the compressor or blower from outside entering the room, increasing the noise level. It was hot.

The present invention eliminates the above-mentioned conventional drawbacks.

Hereinafter, the present invention will be described with reference to FIGS. 1 to 4 of the accompanying drawings showing one embodiment thereof.

In the figure, reference numeral 1 denotes an underframe of an integrated air conditioner, which includes a board 2, a partition plate 3, etc., which is provided on this board 2 and separates an indoor ventilation system path A and an outdoor ventilation system path B. It is made up of. The outdoor ventilation system path B includes an outdoor heat exchanger 5 mounted facing the back surface 4, a motor 6 mounted with its rotating shaft perpendicular to the partition plate 3, and one end of this motor 6. An axial flow fan 7, a compressor 8, etc., which are attached to the indoor heat exchanger 5 and blow air toward the outdoor heat exchanger 5, are installed, and an indoor heat exchanger installed facing the front surface 9 is installed in the indoor ventilation system path A. a heat exchanger 10 attached to the other end of the motor 6;
A multi-blade fan 1 blows out the wind passing through the wind tunnel section 11.
There is a 2nd prize. The outer box 13 into which the underframe 1 is inserted has an opening 14 for insertion, and beads on the left side 16 and right side 17 of the top surface 15 so as to face the inside of the outer box 13 and follow the outer periphery of the partition plate 3. A protruding band 18 having a shape is provided.

In the above configuration, when the underframe 1 is inserted into the outer box 13, the outer periphery of the partition plate 3 is
8, and the protruding band 18 of the outer box 13 formed along the outer circumference of the inner partition plate 3 contacts the outer circumference of the inner partition plate 3, thereby forming an indoor ventilation system path A and an outdoor ventilation system path B. A seal is created between. Here the fourth
As shown in the figure, if the cross-sectional shape of the protruding band 18 of the outer box 13 is semicircular, there is an advantage that the strength of the outer box 13 is ensured. Further, as in another embodiment of the present invention shown in FIG. 5, if a sealing material 19 or the like is attached to the opening 14 side of the outer box 13 of the protruding band 18, the sealing performance can be further improved, and the indoor ventilation system Route A and outdoor ventilation system route B
can completely block wind circulation and noise leakage.

As mentioned above, the integrated air conditioner according to the present invention has the following features:
A protruding band is provided on the top and side surfaces of the outer box along the outer periphery of the partition plate of the underframe toward the inside of the outer box, so that when the underframe is inserted into the outer box, the outer periphery of the partition plate touches the protruding band. Because of this position, the mounting position of the underframe to the outer box can be maintained accurately, and the seal between the outer periphery of the partition plate and the protruding band can be ensured, preventing a decrease in capacity due to wind leakage and damage to the indoor side. This has the effect that there is no noise leakage, etc. Furthermore, since the outer box itself is provided with a protruding band, there is no need to attach a separate part to serve as the protruding band, and the structure is simple and inexpensive.
