Description

[Detailed description of the invention] The present invention relates to air conditioners, and in particular improves the insulation material attached to the partition plate that divides the indoor and outdoor areas to improve the indoor and outdoor insulation and sound insulation effects. The insect screen that was previously installed at the ventilation openings was integrated into an integrated structure to reduce the number of parts.

In conventional air conditioners, a partition plate is installed on the main body base to separate the indoor side and the outdoor side, and a heat insulating material made of urethane foam is pasted on the outdoor side of this partition plate for insulation and sound insulation between the indoor and outdoor areas. However, since this insulation material is made of a breathable material, its insulation and sound insulation effects are insufficient. For this reason, a method has been proposed in which the above-mentioned heat insulating material is made of a cardboard-like cross section, and this insulating material is attached to the partition plate using a pin-shaped fixing member. Since a fixing member is required, the number of parts increases, resulting in high cost, and the installation work is extremely complicated. In addition, the above-mentioned partition plate is provided with a ventilation device, that is, a ventilation hole, to ventilate the indoor air, as well as an exhaust damper and an intake damper to open and close the ventilation hole. Since an insect screen is provided that also serves as an insect repellent screen, the installation work is not only very troublesome, but also increases the number of parts and costs.

The present invention eliminates the drawbacks of the above conventional type.
To explain one embodiment of the present invention shown in the figure below, 1
is the main body base of the air conditioner. On the same base 1, an indoor heat exchanger 2 and an outdoor heat exchanger 3, a fan motor 4, a compressor 5, etc. are arranged between these, and the indoor side At the rear of the heat exchanger 2, an indoor fan 6 and a partition plate 7 which also serves as a baffle plate and partitions an indoor side and an outdoor side are arranged. Reference numeral 8 denotes a heat insulating material attached to the outdoor side surface of the partition plate 7, which provides heat and sound insulation between the indoor and outdoor spaces. The partition plate 7 has a ventilation device, for example, a ventilation port 11 located outside the air guide path as shown in the figure, and a ventilation port 11 that is connected to an operating section (not shown) on the front of the main body, facing the ventilation port 11. A rotatable intake damper 12 is provided.

The heat insulating material 8 is formed by molding synthetic resin or the like and has a nail, for example, attached to the partition plate 7 on its surface facing the partition plate 7 as shown in FIGS. 2, 3, and 4. It is formed into a plate shape in which a shaped mounting portion 10 and a rib-shaped protruding portion 9 for forming a required air layer 15 between the partition plate 7 and the partition plate 7 are integrally formed. An insect repellent net section 14 is formed by a large number of small holes 13 opposite to the ventilation opening 11 formed. The partition plate 7 has a thin shape corresponding to the bending portion of the partition plate 7, so that it can be bent freely. On the other hand, the partition plate 7 is formed with a locking part 16 for engaging with the mounting part 10 of the heat insulating material 8.

To explain how the above structure is attached, first, the heat insulating material 8 is bent to fit the shape of the partition plate 7 and attached to the outer surface of the partition plate 7. Then, the heat insulating material 8 is attached to the partition plate 7 by pressing so that the attachment part 10 engages with the locking part 16 of the partition plate 7, and the work is completed. At this time, an air layer 15 is formed between the heat insulating material 8 and the partition plate 7 by the protruding part 9, and an insect screen part 14 is located opposite the ventilation opening 11 of the partition plate 7 to provide a ventilation system. During operation, outside air is sucked into the room through this insect screen section 14. As shown in FIG. 3, it is preferable to form the protrusion 9 on the periphery of the insect screen 14 so as to abut the periphery of the ventilation opening 11, so that the ventilation opening 11 and the insect screen 14 are more in communication with each other.

As described above, in the present invention, the heat insulating material is formed into a synthetic resin plate with mounting parts and protrusions integrally formed on the plate surface facing the partition plate, and small holes are formed opposite the ventilation holes of the partition plate. Since the insect screen part is formed by forming an insect repellent net part and is attached to the partition plate by engaging its mounting part with the locking part of the partition plate, the installation work can be extremely simplified and , The work of attaching an insect screen to the ventilation opening, which was conventionally done, can be omitted. Therefore, since no separate fixing member or insect screen is required, the number of parts can be reduced and costs can be reduced. In addition, when installed, the air layer between the partition plate and the protruding part can improve the insulation effect between indoors and outdoors, and the natural vibration of the partition plate can be improved by this air layer and the heat insulating material. Since the number can be changed, the sound insulation effect can be further improved. Furthermore, these devices can be implemented at low cost with extremely simple configurations as described above.
