Abstract

PURPOSE:To prevent entry of insects simply and positively by a construction wherein a member projecting towards the outdoor is formed integrally with a fan casing around its opening 8 formed therein to communicate the indoor with the outdoor, and the opening in the lower surface of the projecting member is formed integrally with lattice. CONSTITUTION:In a window mounted type air conditioner wherein an indoor heat exchanger 4 and an outdoor heat exchanger 4' are mounted in an integrally formed casing, a fan casing 5 forming air passage with air guider 7 of a fan 6 has an opening 8 formed to communicate the indoor with the outdoor. Formed as an integral unit of the fan casing 5 is a projecting member 11 which is located around the opening 8 and which projects to the outside of the room. Further, the projecting member 11 has an opening formed in the lower surface thereof and which has lattice 12 formed integrally with the fan casing 5. This arrangement eliminates the need for separate provision of an insect catching net for the opening 8 thus enabling a cost saving to be achieved.

Description

[Detailed Description of the Invention] The present invention relates to window-mounted air conditioners, especially those in which a ventilation device is provided in the fan casing and the partition material that partitions the inside of the air conditioner body into an indoor side and an outdoor side. , the material and shape of the fan casing have been improved to prevent dew from forming on the exhaust part due to the exhaust of cold air during cooling, prevent rust from forming due to this dew, and prevent rainwater, insects, etc. from entering the room from the outside. A structure that does not intrude into the interior of the room can be obtained at low cost.

Conventional window-mounted air conditioners of this type have been constructed as shown in FIGS. 6 to 8. In the figure, the fan casing a also serves as an air guider, and the indoor side and the outdoor side are separated by a partition member. The partition material is provided with a hole C that allows communication between the indoor and outdoor areas, and around this hole C, there is a waterproof plate d made of iron plate so that the bottom side is open.
Please weld. In addition, an insect screen e is fixed to the hole C of the partition member with screws f, or the insect screen is attached by welding or the like. Therefore, in the case of this conventional example, materials and processing costs for the waterproof plate d1 insect screen e or screw f, work costs for screwing or welding the waterproof plate d1 insect screen e or e' to the partition material, etc. are required. Yes, and because cold air is blown out during air conditioning, waterproof boards d insect screens e
The present invention provides a window-hung type air conditioner that eliminates the above-mentioned conventional drawbacks, and one embodiment thereof will be described below as a first embodiment. Figure~6th
The explanation will be explained with reference to the figure.

In the figure, 1 is the main body of the air conditioner, and the front side has an inlet 2. A blower outlet 3 is provided respectively. Reference numeral 4 denotes an indoor heat exchanger that constitutes a well-known refrigeration cycle together with a compressor (not shown), an outdoor heat exchanger (49, etc.), and is provided in a ventilation passage formed by the fan casing 5.

The fan casing 6 is molded from synthetic resin material.
The insulation properties are better than those formed by conventional metal plates.

6 is a multi-blade centrifugal type blower provided in the ventilation passage. Reference numeral 7 denotes an air guider of the blower 6, which forms a ventilation path together with the fan casing 5 and partitions the inside of the air conditioner main body 1 into an indoor side and an outdoor side. Reference numeral 8 is for exhausting part of the air passing through the ventilation passage by opening and closing an exhaust door 10 which is provided indoors and outdoors in the fan casing 6.

Reference numeral 11 denotes a convex portion located around the hole 8 of the fan casing 5 and integrally formed with the fan casing 6 on the outdoor side. is formed integrally with the fan casing 6.

The convex portion 11 prevents rainwater from entering from the outside when the exhaust door is opened to exhaust part of the wind passing through the ventilation path, and the grating 12 prevents rainwater from entering from the outside of the room. This is to prevent insects from entering from the outside when 1o is opened.

As is clear from the above structural description, the fan casing 6, the convex portion 11, and the lattice 12 provided at the lower opening of the convex portion
Since it is integrally molded with a heat insulating material such as a synthetic resin material, the material cost and processing cost are low, and the curved part of the ventilation path can be formed with a curved surface, which reduces ventilation resistance. In addition, even if the air discharged from the grid 12 is cold, dew is unlikely to condense on the convex part 11, and even if dew condenses, the convex part 11 and the grating 12
Since the fan casing 6 is made of a synthetic resin material, it does not rust, and the material and processing cost of the fan casing 6 is low.

As is clear from the description of the embodiments above, the air conditioner of the present invention includes an indoor heat exchanger and an indoor heat exchanger in a window-mounted air conditioner main body, which has an inlet and an outlet on the indoor side. A ventilation passage is configured to communicate with an indoor side blower provided corresponding to the inside heat exchanger and the front-distribution inside heat exchanger, and to guide the air sent from the blower toward the outlet. An air guider/inside/outside partition plate and a fan casing made of synthetic resin or the like are provided, and the fan casing is integrally provided with a hole through which the indoor and outdoor communicate with each other, and a convex portion located around this hole and protruding toward the outdoor side. , further forming an opening on the lower surface of the convex portion, and integrally forming a lattice in the opening,
Since a damper is provided to open and close the hole in the fan casing, a portion of the wind passing through the ventilation path is exhausted from the hole to provide good ventilation, and further prevents the intrusion of rainwater, insects, etc. Since the convex part and grid are integrated, it not only prevents rainwater and insects from entering, but also prevents rust from condensation caused by the cold air exhausted from the iron plate, as well as various other problems caused by condensation.\Various advantages It has the following.
