Description

Technical Field

[0001] The utility model relates to the technical field of mobile air conditioners, and more specifically to an air outlet structure of a mobile air conditioner. Background Art

[0002] Mobile air conditioners are a convenient cooling device widely used in homes, offices, and other places. Compared with traditional fixed air conditioners, mobile air conditioners have advantages such as being free from installation location restrictions and easy to move.

[0003] Existing mobile air conditioners are provided with an impeller and an air outlet cavity. The rotation of the impeller generates airflow in the air outlet cavity, and the airflow in the air outlet cavity is directly blown out through the air outlet provided on the outer shell. In this type of structure, the airflow is only guided and blown out through the air guide blades provided in the air outlet. However, since the structure of the air outlet cavity does not have an airflow guiding structure, the blown airflow may undergo unstable convection, affecting the air outlet effect and resulting in a poor user experience.

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0025] A mobile air conditioner air outlet structure, please refer to Figure 1-4, including a shell 100, the shell 100 is a rectangular parallelepiped structure, an air outlet cavity 101 is formed in the shell 100, an air outlet cover 200 is provided on the front side of the air outlet cavity 101, an air duct cover body 300 is connected to the rear side of the air outlet cover 200, an impeller 310 is provided in the air duct cover body 300, a first connecting port 320 is provided on the side of the air duct cover body 300 close to the air outlet cover 200, a second connecting port 210 matching the first connecting port 320 is provided on the side of the air outlet cover 200 close to the air duct cover body 300, an air outlet 220 is provided on the front side of the air outlet cover 200, and a first air guide arc surface 230 and a second air guide arc surface 240 are provided on the left and right sides of the air outlet cover 200 respectively; in addition to the air outlet cavity 101, the space in the shell 100 is generally also provided with a compressor , circuit boards, condensers, heat dissipation channels and other components. This is the existing technology and will not be elaborated on in detail. When the mobile air conditioner is working, the impeller 310 in the air outlet chamber 101 rotates to blow the air flow in the direction of the first connecting port 320. Then the air flow enters the air outlet cover 200 through the second connecting port 210. After the air flow enters the air outlet cover 200, it is blown out of the air outlet 220 through the guidance of the first air guide arc surface 230 and the second air guide arc surface 240. The air outlet cover 200 guides the air flow evenly and then blows it out. The air outlet of the mobile air conditioner is more stable and smooth. When the air is out, the air flow is blown out in a positive direction to the outside through the guidance of the first air guide arc surface 230 and the second air guide arc surface 240, which has a good user experience. In conjunction with the air outlet 220, it can be set to an outward-expanding arc surface structure to increase the wind range.

[0026] Furthermore, an oblique air guide cover plate 250 is formed on the air outlet cover 200 between the second air guide arc surface 240 and the second connecting port 210. Since the second connecting port 210 on the air outlet cover 200 is located on the right side, when the airflow formed in the air duct cover body 300 enters the air outlet cover 200, part of the airflow is blown forward through the guidance of the first air guide arc surface 230, and part of the airflow is guided toward the direction of the second air guide arc surface 240 through the oblique air guide cover plate 250, and then guided and blown forward through the second air guide arc surface 240. The overall guiding structure on the air outlet cover 200 allows the airflow entering therein to be blown out evenly, ensuring the stable air supply of the mobile air conditioner. The air supply effect is improved through structural improvements, which has a relatively energy-saving effect.

[0027] Furthermore, a grille cover 106 connected to the air outlet 220 is provided at a position on the outer shell 100 corresponding to the air outlet hood 200. The grille cover 106 is the air outlet position on the outer shell 100. The gas in the air outlet cavity 101 is sent to the air outlet hood 200 through the impeller 310 and is blown forward through the guide, and finally blown out of the outer shell 100 through the grille cover 106. The grille cover 106 can prevent foreign objects from entering the air outlet hood 200, or prevent children from reaching into the air outlet hood 200 or even the air duct cover body 300; a plurality of rotatable air guide blades 260 are provided on the air outlet hood 200, and the plurality of air guide blades 260 are connected with a linkage rod so that the plurality of air guide blades 260 can rotate at the same time. According to actual needs, the air guide blades 260 can be rotated manually or electrically, and the left and right air outlet adjustment of the mobile air conditioner can be achieved by swinging the air guide blades 260.

[0028] Furthermore, the air duct cover 300 is provided with a cavity 330 that passes through from top to bottom, the impeller 310 is located in the cavity 330, the air duct cover 300 is connected to the air outlet cavity 101 through the top of the cavity 330, the bottom of the air outlet cavity 101 is provided with a motor 102 connected to the impeller 310, the air outlet cavity 101 is provided with an evaporator 103 on the side away from the air outlet cover 200, and the shell 100 is provided with a middle partition 104, which forms a partition for the internal space of the shell 100. The air outlet cavity 101, the bottom of the air duct cover 300 is sealed and connected to the middle partition 104, and the middle partition 104 is fixed horizontally in the shell 100, so that the space in the shell 100 is divided into two parts, the upper part is the air outlet cavity 101, and the motor 102 is located below the middle partition 104. The rotating shaft on the motor 102 passes through the middle partition 104 and extends into the air outlet cavity 101 and connects to the impeller 310. The air duct cover 300 wraps the impeller 310 through the cavity 330. The bottom of the air duct cover 300 is sealed and connected to the middle partition 104. When the motor 102 is running, it drives the impeller 310 to rotate. When the impeller 310 rotates, it draws air from the air outlet cavity 101 through the opening at the top of the air duct cover 300 and blows it toward the air outlet cover 200. The air duct cover 300 forms a ventilation channel for the air flow. After the air flow enters the air duct cover 300, it can be concentrated and blown toward the air outlet cover 200. Compared with a structure without the air duct cover 300, the air flow can be blown to the air outlet cover 200 more stably and concentratedly. With the function of the air outlet cover 200, the air outlet speed of the air conditioner is higher at the same rotation speed of the impeller 310. The evaporator 103 on the rear side of the air outlet cavity 101 is used to cool the air. The housing 100 is provided with a ventilation hole 105 connected to the air outlet cavity 101. Air outside the housing 100 can enter the air outlet cavity 101 through the ventilation hole 105, which is conducive to the flow balance of the air inside and outside the air outlet cavity 101 when the mobile air conditioner is working.

[0029] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
