DETAILED DESCRIPTION

[0055] Example

[0056] The embodiment of the present invention provides a mobile air conditioner 100 , which can reduce the processing cost and difficulty of the panel 130 .

[0057] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0058] Please refer to Figures 1 to 4, The mobile air conditioner 100 includes a rear housing 110, a panel 130, and a grille cover 150. The panel 130 is provided with air outlet holes 121, and a clamping structure 131 is provided at the periphery of the air outlet holes 121. The grille cover 150 is installed in the air outlet holes 121, and a mating structure 151 that cooperates with the clamping structure 131 is provided on the grille cover 150. The mating structure 151 is clamped to the clamping structure 131, and the panel 130 is installed on the rear housing 110.

[0059] In this embodiment, the panel 130 and the grille cover 150 are processed separately, which can reduce the processing difficulty and the cost of mold manufacturing. A clamping structure 131 is provided at the outer peripheral edge of the air outlet holes 121 of the panel 130, and a mating structure 151 is provided on the grille cover 150. In this way, the assembly of the grille cover 150 and the panel 130 can be conveniently realized through the clamping between the clamping structure 131 and the mating structure 151, making the installation convenient.

[0060] In this embodiment, the panel 130 and the grille cover 150 are prepared and formed by separate injection molding. The general shape of the panel 130 is in a U shape, and both sides of its horizontal section slightly protrude from the panel 130 to be connected to the rear housing 110. At the connection between the horizontal section and the vertical end, an arc surface is used for transition.

[0061] In this embodiment, the air outlet holes 121 are circular. The grille cover 150 is circular, and the value of the diameter ranges from 250 mm to 280 mm. The grille cover 150 first gradually protrudes outward from the edge towards the center, and then gradually concaves inward. The center of the grille cover 150 is concave, and the radius is slightly convex near the center, thus realizing an arc transition. And it fits with the arc transition of the panel 130, making it more beautiful and beneficial to air outlet. A plurality of air outlet grilles 153 are arranged on the grille cover 150 at intervals, and the air outlet grilles 153 extend from the center of the grille cover 150 towards the edge. And it bends and extends in the clockwise direction. Along the length direction of the air outlet grille 153, the width of the air outlet grille 153 first gradually becomes wider and then gradually becomes narrower. It can be understood that the air outlet grille 153 spirally extends from the center of the grille cover 150 towards the edge in the clockwise direction. The interval between adjacent two of the ends of the air outlet grilles 153 close to the center of the grille cover 150 ranges from 2 mm to 4 mm, the spacing at the widest part in the middle ranges from 8 mm to 12 mm, and the spacing at the other end ranges from 3 mm to 5 mm. For example, 3 mm, 10 mm, and 4 mm can be taken as a group.

[0062] Through the above optimization of the structure of the grille cover 150 and the shape and rotation direction of the air outlet grilles 153, the air output of the mobile fan can be improved.

[0063] Please refer to Figure 3 to Figure 4In this embodiment, the snap-fit ​​structure 131 is a snap 133, which is disposed on the inner side of the panel 130, and the matching structure 151 is a slot 155. The grille cover 150 is mounted on the inner side of the panel 130 and partially mounted in the air outlet 121. The snap 133 is snapped into the slot 155.

[0064] Since the panel 130 has a certain thickness, the buckle 133 is protruded on the inner side of the panel 130, which can reduce the cost of the mold and make the assembled structure invisible from the appearance of the assembled panel 130, making the appearance more complete and beautiful. Secondly, the cooperation between the buckle 133 and the slot 155 can achieve both snap connection and position limiting.

[0065] Of course, in some embodiments of the present application, the positions of the buckle 133 and the slot 155 may be swapped, that is, the buckle 133 may be set on the grille cover 150 , and the slot 155 may be set on the panel 130 .

[0066] In this embodiment, a plurality of connection blocks 157 are spaced apart on the outer periphery of the grille mesh cover 150 , and a slot 155 is disposed on the connection block 157 , and the slot 155 is hole-shaped, and the buckle 133 passes through the slot 155 and is engaged with the rear surface of the connection block 157 .

[0067] A connection block 157 is provided on the outer periphery of the grille cover 150, and a hole-shaped card slot 155 is provided on the connection block 157 so that the buckle 133 can be inserted into the hole and snapped onto the connection block 157, thereby making installation more convenient. Secondly, the hole-shaped card slot 155 can be matched and connected with the inserted buckle 133, thereby preventing the card connection from failing and falling off, and improving the connection strength.

[0068] Please refer to Figure 4 In this embodiment, the protrusion of the buckle 133 is convex toward the outside, and the buckle 133 is tilted toward the outside as a whole, with an inclination angle of 2°. The opening of the slot 155 is set in a structure with one side larger and the other side smaller, that is, the cross section of the slot 155 is roughly trapezoidal. In this way, when the grille cover 150 is installed, the buckle 133 can be easily inserted into the slot 155. Then, the grille cover 150 is pressed to guide the side wall of the slot 155 so that the buckle 133 is deformed and passes over the side wall of the slot 155, so as to be clamped on the end face of the connecting block 157.

[0069] Please refer to Figure 2 Specifically, three buckles 133 are provided, one is provided above the grille cover 150, and one is provided on both sides. In this way, the positioning and fixing of the grille can be achieved.

[0070] To ensure that the gap between the grille cover 150 and the panel 130 is uniform and the extended portion is balanced. In this embodiment, the outer periphery of the grille cover 150 is provided with a limiting boss 159, and the outer periphery of the air outlet 121 is provided with a limiting portion 135. The limiting boss 159 abuts against the limiting portion 135, so that the shell portion of the grille cover 150 extends out of the air outlet 121.

[0071] By using the limiting boss 159 protruding from the outer edge of the grille cover 150 and the limiting portion 135 provided on the outer periphery of the air outlet 173 to abut against each other, the grille cover 150 can extend out of the air outlet 121 to achieve an aesthetic effect while also achieving positioning and sealing between the two. Secondly, since the grille cover 150 has a high hollowing degree, the limiting boss 159 can also increase the mechanical lightness of the grille cover 150. It should be noted that the limiting portion 135 can be a ring platform or a ring groove.

[0072] Secondly, please refer to Figure 4 In this embodiment, the portion of the grille mesh 150 extending into the air outlet 173 has a certain taper, approximately about 10 degrees, and the side wall of the air outlet 121 is provided with a matching taper, so as to ensure that the gap between the two is uniform and the internal structure cannot be seen.

The fan casing 171 is a volute, and is installed in a cavity formed by the rear housing 110 and the panel 130. The fan casing 171 has an air outlet 173, and the air outlet 173 corresponds to the grille mesh 150. That is, the wind blown out from the air outlet 173 can be blown out through the grille mesh 150. The centrifugal blades 172 are rotatably installed in the fan casing 171. The upper side wall 174 of the air outlet 173 extends obliquely upward. The lower side wall 175 of the air outlet 173 extends obliquely downward.

[0074] The upper side wall 174 of the air outlet 173 extends upwardly and tilts, and the lower side wall 175 extends downwardly and tilts, so that the air outlet 173 is gradually enlarged, thereby increasing the air output.

[0075] Please refer to Figure 7 Generally, the inclination angle of the upper side wall 174 is in the range of 8°-15°, and can be 11°. The inclination angle of the lower side wall 175 of the air outlet 173 is in the range of 30°-40°, and can be 34°. This can correspond to the air outlet 121, thereby increasing the air volume.

[0076] Please refer to Figure 5 , Figure 6 and Figure 7In this embodiment, the end of the lower side wall 175 of the air outlet 173 is connected with a downwardly inclined guide slope 176. The guide surface is roughly arc-shaped, and its projection roughly corresponds to the edge of the grille mesh cover 150. The angle of the guide slope is roughly 3°. The upper side wall 174 of the air outlet 173 is connected with an air guide plate 177, so that the projection of the air outlet 173 of the fan housing 171 forms a quasi-circular shape corresponding to the air outlet hole 121.

[0077] A downwardly inclined guiding slope 176 is provided on the lower side wall 175 of the air outlet 173 so as to correspond to the shape of the air outlet hole 121, thereby increasing the air output.

[0078] In this embodiment, a water retaining rib 178 is protruded outwardly from the outer side of the lower side wall 175 of the air outlet 173. The water retaining rib 178 can guide the condensation formed on the outer side of the fan housing 171 to the water receiving tray below, avoiding flowing along the outer wall of the fan housing 171 and flowing to the air outlet 121.

[0079] Please refer to Figures 5 to 9 In this embodiment, an upper guide plate 179 is protruded inwardly on the upper side wall 174 of the air outlet 173, and a lower guide plate 181 is protruded inwardly on the lower side of the air outlet 173. The distance between the end faces of the upper guide plate 179 and the lower guide plate 181 and the end face of the air outlet 173 is about 30 mm. The angle between the upper guide plate 179 and the vertical plane ranges from 15° to 20°. The length of the upper guide plate 179 ranges from 40 mm to 60 mm, and the thickness of the upper guide plate 179 ranges from 1.5 mm to 2.5 mm. The height of the upper guide plate 179 ranges from 15 mm to 20 mm.

[0080] By providing the upper guide vane 179 and the lower guide vane 181 , whistling can be prevented and wind noise can be reduced.

[0081] Please refer to Figures 5 to 9In the present embodiment, the mobile air conditioner 100 further includes a protective grid 190.
