DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a duct device for a mobile air conditioner that performs air cooling to exchange heat outside the room.

Conventional technology Conventionally, this type of mobile air conditioner has a water tank installed inside the air conditioner main body, and the water in the water tank is sprinkled onto an outdoor heat exchanger to collect latent heat of evaporation and perform heat exchange. I was going.

The seventh problem that the invention aims to solve is that the above-mentioned conventional mobile air conditioners always require water for heat exchange outside the room. Not only does it require regular replenishment of water with the installation of a tank, but the noise generated when water is sprinkled onto the outdoor heat exchanger is annoying, and the heat exchanger also becomes easily contaminated with limescale, making it a hassle. Regular maintenance is required, and since the water tank is provided, the main body size is large (necessitating wasted installation space and is heavy, making it difficult to move easily).

In view of the above-mentioned conventional problems, the present invention aims to make the outdoor heat exchange of a portable integrated air conditioner air-cooled, thereby making it easier to move and maintenance-free.

Means for Solving the Problems In order to solve the above problems, the present invention provides a mobile air conditioner with a duct on the outdoor side that divides the interior into two, one for intake air and the other for exhaust air. .

Further, in the present invention, the duct is of a bellows type, and the outer periphery of the peaks of the peaks is made hard, and the space between the peaks of the peaks is made of soft integral molding.

Further, in the present invention, the duct is divided into upper and lower halves, the upper part is the exhaust side, and the upper and lower ends of the air outlet are integrally formed with the duct and are formed upward.

Furthermore, in the present invention, seven flanges are integrally formed at the end of the duct and are spaced apart from the outer periphery of the duct by a predetermined distance.

For production The effects of the above means are as follows.

The present invention provides a portable, simple integrated air conditioner with a duct that divides the interior into two on the outdoor side, with one side for intake air and the other side for exhaust air, thereby making it possible to perform heat exchange on the outdoor side by air cooling. It becomes possible.

Further, in the present invention, by making the duct into a bellows type, the duct can move freely in the vertical and front-back directions, and by making the outer periphery of the top of the peak of the bellows hard, the opening of the duct can be cut easily. Deformation of the area can be prevented, and a predetermined intake and exhaust area can always be ensured.

Further, in the present invention, the duct is divided into upper and lower halves, the upper part is the exhaust side, and the upper and lower ends of the air outlet are integrally formed with the duct so as to face upward, thereby preventing high temperature exhaust air from being sucked into the intake side of the lower part. This enables efficient use of the outdoor heat exchanger.

Furthermore, in the present invention, a flange having a predetermined interval outwardly from the outer periphery of the duct is formed integrally with the duct at the end of the duct, so that when the air conditioner is operated, the gap to the window of the duct is reduced. Installation without using any other parts is easily possible.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

First, a first embodiment of the present invention will be described with reference to FIGS. 1 and 2.

In the figure, 1 is the main body of the air conditioner installed indoors,
An indoor air inlet 2 is provided on the front surface of the indoor air inlet 2, and air is sucked in from the indoor air inlet 2 by an indoor fan 8, cooled by an indoor heat exchanger 7, and then blown out from an outdoor air outlet 3.

Further, a duct 4 whose interior is divided into two is provided on the back side of the air conditioner main body 1, and the duct 4 is attached to a window or the like by an installation plate 5 provided at the end thereof.

In the above configuration, when the air conditioner main body 1 is operated,
Outdoor air sucked in from one outdoor side suction port 15 of the duct 4 whose interior is divided into two is heat exchanged by the outdoor side fan 10 in the outdoor side heat exchanger 9, guided by the outdoor side air guider 11, and then The air is discharged outdoors from the outdoor air outlet 14 on one side of the duct 4.

As is clear from the above, since the outdoor heat exchanger 9 is configured to be cooled with outdoor air, there is no need for water for outdoor heat exchange, and there is no need to provide a water tank inside the main body. (Furthermore, the sound of the cooling water during operation and the dirt caused by water scale on the heat exchanger are eliminated, so troublesome regular maintenance is no longer required.

Furthermore, since a water tank is not required, the size of the main body becomes smaller and the weight becomes lower, making it easier to move and install.

Next, a second embodiment of the present invention will be described with reference to FIG.

Here, the same parts as those in the first embodiment are given the same reference numerals and the description thereof will be omitted.

In the figure, reference numeral 4 denotes a bellows-type intake/exhaust duct, with soft duct parts 17 in the valleys and hard duct parts 16 in the outer layer at the peaks.
are integrally molded.

In the above configuration, the installation plate 5 provided at the extreme end of the duct 4 can be freely moved up and down, back and forth, etc., and can be attached to a window in any position.
By molding the outer periphery 16 of the peak of the duct 4 with hard material, the installation plate 5 attached to the air conditioner main body 1 and the window
It is possible to prevent the deformation of the opening cross-sectional area of the duct 4 that occurs due to the positional relationship with the duct 4, and because a predetermined intake and exhaust area can always be obtained, it is possible to easily secure a predetermined air volume that greatly affects performance.

Next, a third embodiment of the present invention will be described with reference to FIG.

In the same figure, 18 is integrated with the duct 4, and the duct 4 is integrated with the duct 4.
It is an outdoor blow-off guide provided at the extreme end of the duct 4, and is located on the exhaust side located above the interior of the duct 4, which is divided into two, and both the upper and lower sides of the exhaust port are formed upward.

In the above configuration, even if the high-temperature exhaust air that has been heat exchanged by the outdoor heat exchanger 9 is blown from the duct 4, it is blown out obliquely upward at the outdoor outlet 14, so that the exhaust air is located at the lower part of the outlet. High temperature exhaust air is not re-inhaled into the outdoor suction port 15.

Therefore, since air at the same outdoor temperature is taken in from the outdoor suction port 15, the outdoor heat exchanger 9 can exhibit a predetermined heat exchange capability, and efficient heat exchange is possible.

Furthermore, a fourth embodiment of the present invention will be described with reference to FIGS. 1 and 2.

In the figure, 5 is located at the end of the duct 4.
It is an installation plate provided with flanges having a predetermined interval on the outside from the outer periphery of the duct 4, and is formed integrally with the duct 4.

In the above configuration, the installation plate 5 makes it possible to attach the duct 4 to the window without using other members, and since the installation plate 5 can be cut according to the width of the window, it is possible to install the duct 4 to the window. It can be easily installed without any restrictions.

Effects of the Invention As is clear from the embodiments described above, the present invention provides a duct on the outdoor side of a mobile air conditioner that divides the interior into two, with one side for intake air and the other side for exhaust air. It is now possible to perform heat exchange by air cooling, which not only eliminates the need for maintenance such as installing a water tank inside the main unit and periodically replenishing water, but also significantly reduces the size and weight of the main unit. This makes it easier to move.

In addition, by making the duct into a bellows type, the duct can move freely in the vertical and front-back directions, making it easier to install the duct in windows, etc., and the outer periphery of the peak of the bellows is made hard. This prevents deformation of the duct opening cross-sectional area and always provides a predetermined intake/exhaust area, making it easy to ensure a predetermined air volume and always providing stable performance.

In addition, the inside of the duct is divided into two parts, with the upper part serving as the exhaust side, and the upper and lower blowout guides at the end of the blowout outlet being integrally formed with the duct and facing upward. There is no re-intake into the intake side, making it possible to ensure stable performance and efficient use of the outdoor heat exchanger.

Furthermore, by forming an installation plate at the end of the duct with a flange having a predetermined distance outward from the outer periphery of the duct, there is no need to use other components (the duct can be attached to windows, etc.). This is easily possible, and furthermore, since the installation plate can be cut to match the size of the window, it can be easily installed inside any window.
