Description

Technical Field

[0002] As a convenient refrigeration device, mobile air conditioners are widely used in homes, offices and other places. Compared with traditional fixed air conditioners, mobile air conditioners have the advantages of not being restricted by installation location and being easy to move.

[0003] Existing mobile air conditioners are usually provided with an air outlet cavity formed in an outer shell and an air outlet connected to the air outlet cavity on the outer shell. After the cold air is formed in the air outlet cavity, it is blown out through the air outlet. When the temperature in the air outlet cavity is low and the temperature outside the outer shell is low, the low temperature in the air outlet cavity will be transmitted outward through the outer shell, resulting in affecting the air outlet temperature. Some mobile air conditioners will lay thermal insulation cotton on the inside of the outer shell, but the production efficiency of such structure is relatively low and the cost is relatively high. In addition, when the temperature difference between the inside and the outside is large, condensation water will form on the outer shell, which will pollute the surrounding environment and affect the user experience.

This is a prior art and will not be described in detail. As shown in the figure, the housing 100 of the mobile air conditioner is a rectangular parallelepiped structure, and the air outlet cavity 101 is located in the upper half of the housing 100. The middle partition 130 is horizontally arranged in the housing 100, so that the housing 100 is partitioned to form the air outlet cavity 101. The top of the air outlet cavity 101 is the top surface of the housing 100, and the left and right sides are the side panels of the housing 100. The middle partition 130 serves as the bottom of the air outlet cavity 101. The front side of the air outlet cavity 101 is the air outlet assembly 110, and the rear side is the evaporator 120. The front and rear sides of the outer air duct cover 160 are respectively connected to the air outlet assembly 110 and the evaporator 120. When the first impeller 180 located in the center of the air outlet chamber 101 rotates, the external air is cooled by the evaporator 120 and then sucked into the inner air duct cover 170 by the first impeller 180, and then blown to the air outlet assembly 110 connected to the front section of the inner air duct cover 170. The outer air duct cover 160 wraps the inner air duct cover 170 therein. During the exhaust and blowing process of the first impeller 180, the air enters the outer shell 100 and only passes through the outer air duct cover 160. The outer air duct cover 160 can make the external air more concentrated after entering, and play a role in gathering and guiding the airflow. In the previous mobile air-conditioning structure, it is necessary to set thermal insulation cotton on the inner side of the outer shell for heat insulation. In the utility model, the flow of air is isolated by the outer air duct cover 160, which plays a role in heat insulation. Thermal effect: When the air conditioner is running in a hot and humid environment, due to the high external temperature and low internal temperature, condensation may appear on the outer shell of the air conditioner, polluting the outside and affecting the user experience. The utility model insulates through the function of the external air duct cover 160. When the temperature difference between the air between the external air duct cover 160 and the outer shell 100 and the air inside the external air duct cover 160 is large, especially when the air conditioner is used frequently in hot and humid weather, condensation will still form on the outside of the external air duct cover 160. At this time, the condensation on the outside of the external air duct cover 160 will drip downward along the side wall, and finally fall into the water receiving groove 131 on the outside of the middle partition 130 for collection, so as to prevent the condensation from dripping downward and polluting the components below the air outlet cavity 101 inside the outer shell 100.

[0026] Furthermore, the middle partition 130 divides the internal space of the outer shell 100 to form the air outlet chamber 101. The middle partition 130 is horizontally arranged in the outer shell 100 to divide the internal space of the outer shell 100 into two parts, the upper and lower parts. The part above the middle partition 130 is the air outlet chamber 101. The middle partition 130 is used to support and fix the outer air duct cover 160, the inner air duct cover 170 and other components; the outer air duct cover 160 is mounted on the middle partition 130, and the outer air duct cover 160 is a cover-like structure with the bottom sealed and connected to the middle partition 130. The outer air duct cover 160 isolates the inner air duct cover 170 inside it. A motor connected to a first impeller 180 is provided below the middle partition 130. The motor is fixed below the middle partition 130. The rotating shaft on the motor passes through the middle partition 130 and extends into the inner air duct cover 170. The first impeller 180 is connected to the rotating shaft of the motor.

[0027] Furthermore, openings corresponding to the air outlet assembly 110 and the evaporator 120 are respectively provided on both sides of the external air duct cover 160. The external air duct cover 160 is covered and fixed on the middle partition 130 and connects the air outlet assembly 110 and the evaporator 120. The air outlet assembly 110 and the evaporator 120 are respectively located at the openings of the external air duct cover 160 and close them. The external air duct cover 160 is covered and fixed on the middle partition 130 so that an independent cavity is formed inside it, which plays a role in heat preservation; an air outlet 111 is provided on the side of the air outlet assembly 110 close to the outer shell, and the outer shell 100 is provided with an opening matching the air outlet 111. The air outlet assembly 110 is connected to the outside of the outer shell 100 through the cooperation of the air outlet 111 and the opening. The first impeller 180 sucks the air in the inner air duct cover 170 through the air outlet assembly 110 and blows it toward the air outlet 111, and finally blows it out to the outside through the opening on the outer shell 100.

[0028] Furthermore, the inner air duct cover 170 is provided with a through hole 171 which runs through from top to bottom, the air outlet assembly 110 is provided with a first connecting hole 112 on one side close to the inner air duct cover 170, and the inner air duct cover 170 is provided with a second connecting hole 172 which matches the first connecting hole 112 on the side thereof, and the inner air duct cover 170 is connected to the air outlet assembly through the cooperation of the first connecting hole 112 and the second connecting hole 172, and the two are connected and the interior is connected, and the air flow can be transported from the inside thereof; the bottom of the inner air duct cover 170 is connected to the middle partition 130, and the middle partition The plate 130 closes the bottom of the through hole 171.
