Description

Technical Field

[0001] The invention relates to a mobile air conditioner, in particular to a mobile air conditioner with obliquely installed coaxial cold and hot air ducts capable of changing the cold air outlet direction. Background Art

[0002] Mobile air conditioners do not need to be installed on windows or walls. They are placed on the ground and can be moved anytime and anywhere. They are easy to use and do not require professional installers. They only need to be simply placed and connected to the power supply. They are easy to operate. Therefore, the use of mobile air conditioners is becoming more and more widespread.

[0003] The wind cavity of the existing mobile air conditioner adopts a horizontal or vertical setting structure, and the air outlet is set on the top or side wall of the shell. When it is set on the side wall, the horizontal height of the outlet is lowered, thereby reducing the air supply distance; when it is set on the top, the angle between the air outlet and the wind cavity is too small, which will form wind resistance and wind noise, and at the same time, affect the air supply distance; or the air outlet is inclined, which increases the installation space, thereby increasing the length or width of the shell, that is, increasing the volume; therefore, the air duct design of the existing mobile air conditioner cannot take into account the air volume, air supply distance and volume.

The upper volute cavity adopts a double air inlet form, which increases the air intake and further increases the wind pressure and air supply distance. The volute assembly adopts a splicing form, which reduces the manufacturing process difficulty, improves the overall precision, and is easy to assemble, maintain and maintain. And low cost of use; side baffles are arranged on the upper volute to form a docking port for air intake and drainage, which reduces internal wind resistance and wind noise, ensures a sufficiently large air inlet diameter and air intake volume, and has low working noise; the upper volute assembly is arranged at the upper end of the lower volute assembly, and the top surface of the lower volute assembly serves as the bottom plate of the upper volute assembly, which reduces manufacturing cost and installation space and improves structural compactness; reinforcing ribs are arranged on the side baffles to improve the structural rigidity of the side baffles, avoid damage during assembly, improve structural reliability, and at the same time, avoid vibration and noise during operation, so as to achieve good use effect and long service life; the mobile air conditioner with obliquely installed coaxial hot and cold air ducts that can change the cold air outlet direction of the present invention has compact structure, small size, low manufacturing cost and use cost, easy assembly, high air outlet speed, long air supply distance, low working noise, good use effect and long service life.

[0084] Compared with the existing flat-mounted air duct, the oblique-mounted air duct used in the present application has a longer air supply distance and less wind noise.

[0085] The existing flat-mounted air duct is compared with the oblique-mounted air duct (with an inclination angle of 10 degrees) in this application. The two are tested in the same environment, where the test environment temperature is 25 degrees, there is no wind indoors, the hot air is drained to the outside through the air duct, the length of the air outlet duct at the cold air end is 1.5m, and its inclination angle with the horizontal plane is 30 degrees, see the following table:

[0086]

[0087] It can be seen from the above test data that compared with the existing air duct design, the present application adopts an oblique air duct, which makes the air outlet pressure (wind speed) greater, the air supply distance longer, and the use effect better; wherein, the above-mentioned felt air supply distance refers to the horizontal distance from the outlet end of the air duct to the end where there is no wind feeling; the obliquely mounted single-motor structure in the present application, compared with the existing air duct design, the air outlet wind speed is increased by about 15%-19%, the air supply distance is increased by 15%-20%, and the cooling effect is better, the performance is significantly improved, the use effect is better, and the experience is better.

The obliquely installed air duct is used to form an angle between the air outlet end and the volute cavity, thereby reducing wind resistance, increasing wind pressure (wind speed), delivering air to a farther distance and achieving better use effect. The upper end air outlet mode is adopted to increase the air outlet height, further increasing the air supply distance. The obliquely installed structure can increase the internal volume of the upper volute, increase the air intake and air outlet, and further increase the wind pressure and air supply distance. The single motor drive reduces the production and manufacturing costs, has low power consumption, and reduces the installation space at the same time, making the overall structure more compact, which is conducive to the miniaturization of the mobile air conditioner. The upper volute cavity adopts a double air inlet form, which increases the air intake and further increases the wind pressure and air supply distance. The volute assembly adopts a splicing form, which reduces the manufacturing process difficulty, improves the overall precision, and is easy to assemble, maintain and maintain. And low cost of use; side baffles are arranged on the upper volute to form a docking port for air intake and drainage, which reduces internal wind resistance and wind noise, ensures a sufficiently large air inlet diameter and air intake volume, and has low working noise; the upper volute assembly is arranged at the upper end of the lower volute assembly, and the top surface of the lower volute assembly serves as the bottom plate of the upper volute assembly, which reduces manufacturing cost and installation space and improves structural compactness; reinforcing ribs are arranged on the side baffles to improve the structural rigidity of the side baffles, avoid damage during assembly, improve structural reliability, and at the same time, avoid vibration and noise during operation, so as to achieve good use effect and long service life; the mobile air conditioner with obliquely installed coaxial hot and cold air ducts that can change the cold air outlet direction of the present invention has compact structure, small size, low manufacturing cost and use cost, easy assembly, high air outlet speed, long air supply distance, low working noise, good use effect and long service life.
