Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an attachment device for attaching a ventilation door of an air conditioner to a duct or the like made of a foam material such as expanded polystyrene.

Prior Art Conventionally, this type of ventilation door mounting device had a structure as shown in FIG.

That is, the fan casing and duct (not shown) are integrated into the upper and lower parts, and the ventilation hole is a square hole with no open part, so insert the ventilation door fixture 14 along the claw 15, and then press the claw 15. It was designed to be fixed by bending it as shown by the broken line.

Problems to be Solved by the Invention However, with such a structure, it is necessary to bend the claw 15 in order to fix the ventilation door fixture 14 to the duct (not shown), and in this case, a very large force is applied to the duct. This creates broken lines in the duct and requires a plurality of claws 15 to securely fix the ventilation door fixture 14 in place, making it very time consuming to fix the ventilation door fixture 14.

Therefore, the present invention is intended to prevent damage to the duct and to securely fix the ventilation door fixture in a short period of time.

Means to Solve the Problems The technical means of the present invention to solve the above problems is to divide the fan casing and duct into upper and lower halves, and to open the divided part of the duct to communicate between the indoor and outdoor areas. A U-shaped hole is provided.

Effect The effect of this technical means is as follows.

In other words, since a part of the ventilation hole (U-shaped hole) provided in the duct is open, the ventilation door mount can be installed by inserting it, and all you have to do is assemble the fan casing and duct, which is divided into upper and lower halves. It is also possible to prevent the ventilation door attachment from coming off, and it can be firmly fixed.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings.

In Figures 1 to 4, 1 is a suction port;
In a well-known air conditioner main body 11, an indoor heat exchanger 3, an air blower 4 provided opposite to the indoor heat exchanger 3, and further communicated with the indoor heat exchanger 3 and the air blower are provided. Air sent from 4 is sent to outlet 2
A fan casing 6 constituting a ventilation passage to guide the air in the direction, and a duct 5 integrated with the fan casing 6.
and. The fan casing 6 and duct 5 are each divided into a lower fan casing 6a, an upper fan casing 6b, a lower duct 5a, and an upper duct 5b, and are further divided into either the upper or lower duct 5 (in this case, the lower duct 5a will be explained later). The divided portion is open and a U-shaped hole 10 (ventilation hole) is provided to communicate between the indoor and outdoor areas.

With the above configuration, the ventilation door 7 is fixed to the duct 5a, and a ventilation door mounting tool 8 is used to open and close the ventilation door 7 by operating a wire or the like (not shown) to perform ventilation.
can be installed by simply inserting it into the open part of the U-shaped hole 10 of the lower duct 5a, and furthermore, by assembling and fixing the upper duct 5b on the lower duct 5a, the ventilation door fixture 8 can be prevented from coming off. It can be fixed securely.

Effects of the Invention As described above, the present invention allows the duct that constitutes the ventilation path to be moved up and down in order to guide the air sent from the indoor blower toward the outlet. In addition to dividing the duct into two parts, by opening a part of the duct and creating a U-shaped hole (ventilation hole) that connects the indoor and outdoor areas, the ventilation door mount can be used to open the U-shaped hole in the duct. Since it can be installed by simply inserting it from the bottom, it can be installed in a short time, and it can be installed without applying strong force to the duct, so there is no chance of damaging the duct. Furthermore, after attaching the ventilation door fixture to either the upper or lower duct, the ventilation door fixture can be held down by assembling and fixing the upper and lower ducts, which provides various advantages such as preventing it from coming off and ensuring secure fixation. It is something that you have.
