[0039] The technical solutions of the present utility model will be described clearly and completely below with reference to the accompanying drawings. Obviously, the following described embodiments are some embodiments of the present utility model, not all embodiments.

[0040] Refer to Figure 1 As shown, the top-mounted air conditioner 10 provided by the embodiment of the present utility model includes a chassis 100 and a top cover (not shown in the figure). The top cover is connected to the chassis 100, and an air inlet 110 and an air outlet 120 are provided at the bottom of the chassis 100. The top-mounted air conditioner 10 is installed on the top of the vehicle, and the chassis 100 is connected to the outside of the top of the vehicle. An installation opening (not shown in the figure) is provided on the top of the vehicle, and the air inlet 110 and the air outlet 120 are respectively communicated with the indoor environment of the vehicle through the installation opening. Specifically, the air inlet 110 is an indoor air inlet, and the air outlet 120 is an indoor air outlet.

[0041] Refer to Figure 1As shown, the overhead air conditioner 10 further includes a panel 300. The panel 300 is installed on the inner side of the vehicle top and covers the installation opening, that is, the panel 300 is located in the interior environment of the vehicle. The panel 300 is provided with an air supply opening 310 and an air return opening 320. Among them, the air supply opening 310 is communicated with the air outlet 120, and the air return opening 320 is communicated with the air inlet 110. Indoor air flow enters the air conditioner interior successively through the air return opening 320 and the air inlet 110, and after heat exchange, it sends air to the interior successively through the air outlet 120 and the air supply opening 310.

[0042] Referring to Figure 1 As shown, an installation member 200 is provided at the bottom of the chassis 100. The chassis 100 is connected to the vehicle through the installation member 200. The installation member 200 is provided with an opening 210. The opening 210 is disposed opposite to the installation opening. The air supply opening 310, the installation opening, the opening 210, and the air outlet 120 are communicated in sequence from bottom to top to form an air supply channel, and the air return opening 320, the installation opening, the opening 210, and the air inlet 110 are communicated in sequence from bottom to top to form an air return channel.

[0043] Exemplarily, the installation member 200 is a plate body or a bracket structure to ensure that the chassis 100 can be stably fixed on the vehicle top.

[0044] Exemplarily, the air supply opening 310 and the air return opening 320 can be provided on different panels 300. For example, an air outlet panel and an air return panel are provided inside the vehicle. The air outlet panel is provided with the air supply opening 310, and the air return panel is provided with the air return opening 320.

[0045] Referring to Figure 3 As shown, in some embodiments, a sealing member 500 is added between the chassis 100 and the panel 300. The air supply channel and the air return channel are separated by the sealing member 500. For example, the sealing member 500 can be made of materials such as sponge and foam, which has an effective sealing effect and avoids interference between the air supply and air return of the air conditioner. In addition, the sealing member 500 can also be disposed on the side of the installation member 200 facing the panel 300 and is arranged around the opening 210 to improve the sealing performance between the chassis 100 and the vehicle top.

[0046] In other embodiments, a first opening and a second opening can also be provided on the installation member 200. The first opening and the second opening are spaced apart. The first opening communicates the air supply opening 310 with the air outlet 120, and the second opening communicates the air return opening 320 with the air inlet 110 to adapt to different installation requirements.

[0047] It is understandable that an installation cavity is defined between the chassis 100 and the top cover. Components such as the compressor, evaporator, condenser, and wind wheel 400 of the roof-mounted air conditioner 10 are all arranged in the installation cavity. Among them, when the wind wheel 400 operates, it can generate negative pressure, enabling indoor air flow to enter the air conditioner and be sent out from the air outlet 310 after heat exchange. In the embodiment, the wind wheel 400 is arranged at a position in the installation cavity close to the air outlet 120, and the air supply efficiency is higher.

[0048] Considering that since the wind wheel 400 is exposed at the air outlet 120, a person's finger or other object can reach into the interior of the air conditioner from the air outlet 120 to touch the wind wheel 400. Although the installation opening is blocked by the panel 300 inside the vehicle, there is still a risk that a finger can reach through the air outlet 310 and touch the wind wheel 400, presenting a safety hazard. With the continuous improvement of safety regulations in various countries or regions, the prevention requirements for reaching in through the panel 300 to touch the wind wheel 400 are also getting higher and higher. Therefore, in the embodiment of the present utility model, by adding a protective net 220 at the installation part 200, it can prevent fingers or other objects from reaching through the air outlet 310 to touch the wind wheel 400, effectively improving the protection performance of the roof-mounted air conditioner 10 and greatly reducing the safety hazard.

[0049] Specifically, the protective net 220 is connected to the installation part 200 and is located at the opening 210. Along the direction of the opening 210 towards the air outlet 120, the protective net 220 covers at least part of the air outlet 120, that is, the protective net 220 can cover a part of the air outlet 120 or the entire air outlet 120.

[0050] For Figure 1 the illustrated example for explanation, the air outlet 310, installation opening, opening 210, and air outlet 120 are distributed in sequence from bottom to top. The direction of the air outlet 310 towards the air outlet 120 is from bottom to top. When the protective net 220 covers a part of the air outlet 120, it means that in the direction from bottom to top, the projection of the protective net 220 coincides with part of the air outlet 120. When the protective net 220 covers the entire air outlet 120, it means that the projection of the protective net 220 completely covers the air outlet 120, so that the protective net 220 can block part of the air supply channel or completely block the air supply channel.

[0051] When the protective net 220 covers a part of the air outlet 120, part of the air supply channel is blocked, reducing the risk of fingers or other objects reaching through the air outlet 310 to touch the wind wheel 400. For example, the part of the air outlet 120 directly opposite to the air outlet 310 is covered by the protective net 220, making it difficult for fingers to reach from the air outlet 310 to the air outlet 120.

[0052] When the protective net 220 completely covers the air outlet 120, it can effectively prevent fingers or other objects from reaching into the air supply port 310 to touch the wind wheel 400, improve the protection performance of the top-mounted air conditioner 10, and greatly reduce potential safety hazards.

[0053] Refer to Figure 2 as shown in Figure 2 It shows a simulation test experiment of the protective net 220 blocking an object from touching the wind wheel 400. Using a long strip-shaped object 600 to imitate a human finger, when the long strip-shaped object 600 extends into the air supply channel from the air supply port 310 from bottom to top, the protective net 220 can block the long strip-shaped object 600 from continuing to extend upward, preventing the long strip-shaped object 600 from contacting the wind wheel 400, effectively improving safety and meeting the requirements of safety regulations.

[0054] It should be noted that in the embodiment, the protective net 220 is a mesh structure capable of ventilation. Specifically, the protective net 220 can be formed by cross-connecting multiple mesh strips 222. The protective net 220 has multiple mesh holes 221. The mesh holes 221 can allow air flow to pass through the protective net 220 and can block fingers or objects with sizes close to that of fingers from passing through, which not only meets the protection requirements but also reduces the impact on the air outlet of the air outlet 120.

[0055] Refer to Figure 1 as shown in

[0056] The mounting member 200 is a plate body 201. The plate body 201 is a sheet metal part and is generally square. The mounting opening is formed in the middle of the plate body 201. The plate body 201 is fixedly connected to the chassis 100, playing a role in strengthening the chassis 100. During assembly, multiple bolts pass through the vehicle roof and are connected to the plate body 201 and the chassis 100, making the connection between the chassis 100 and the vehicle more reliable. The plate body 201 is arranged around the air inlet 110 and the air outlet 120, and the size of the mounting opening can meet the requirement of being connected to the air inlet 110 and the air outlet 120 simultaneously. Figure 4 as shown in

[0057] Here is only an example. The shape of the mesh hole 221 is not limited to a rectangle, and it can also be a square, a rhombus, a circle, etc.

[0058] Figure 4In the illustrated embodiment, the protective net 220 is rectangular, and the size of the protective net 220 can cover at least part of the air outlet 120. Specifically, the size of the protective net 220 is set according to the size of the air outlet 120. Since the protective net 220 and the plate body 201 are of a split structure, the installation position of the protective net 220 can be adjusted according to the position of the air outlet 120 to meet different installation requirements.

[0059] Referring to Figure 5 As shown, in some embodiments, the protective net 220 is a metal net, and the plate body 201 is a metal plate. The plate body 201 and the protective net 220 adopt an integrally formed structure. For example, an installation opening and a grille are formed on the metal plate by stamping, and the grille is the protective net 220. The integral structure is more stable and reduces the installation process.

[0060] It can be understood that the smaller the mesh holes 221 are, the greater the resistance of the protective net 220 to air will be, and the ventilation effect will be correspondingly weakened. When the size of the mesh holes 221 is too small, the air circulation will be restricted, so that the air needs to overcome greater resistance when passing through the protective net 220, affecting the air outlet of the air outlet 120. On the contrary, the larger the mesh holes 221 are, the smaller the resistance of the protective net 220 to air will be, and the ventilation effect will be correspondingly enhanced. However, when the mesh holes 221 are too large, although the obstacle to air flow is reduced, the blocking effect on objects is reduced, and fingers or other objects can easily pass through the mesh holes 221 and extend into the air supply channel, posing a safety hazard.

[0061] Therefore, in the embodiment, it is necessary to optimize the size of the mesh holes 221 of the protective net 220 to avoid the size of the mesh holes 221 being too large or too small. Specifically, the size of the mesh holes 221 of the protective net 220 satisfies being greater than or equal to 18 mm and less than or equal to 24 mm.

[0062] Taking Figure 4 the illustrated protective net 220 as an example for illustration, the mesh holes 221 are rectangular, and the size of the mesh holes 221 includes length and width. That is to say, both the length and width ranges of the mesh holes 221 satisfy being greater than or equal to 18 mm and less than or equal to 24 mm. The length of the mesh holes 221 is L, and the width is W. The value ranges of the length L and the width W satisfy: 18 mm ≤ L ≤ 24 mm, 18 mm ≤ W ≤ 24 mm. For example, the length L is 22 mm and the width W is 18 mm. The length and width of the mesh holes 221 can be specifically selected according to actual application requirements.

[0063] It can be understood that when the length or width of the mesh hole 221 is less than 18 mm, it means that the size of the mesh hole 221 is too small, which will limit the air circulation at this time and affect the air outlet of the air outlet 120. When the length or width of the mesh hole 221 is greater than 18 mm, it means that the size of the mesh hole 221 is too large, and the finger is easy to pass through the mesh hole 221, resulting in a decline in the protection effect. Therefore, when the mesh hole 221 is in the shape of a polygon such as a rectangle, a square, or a rhombus, the side length dimension range is greater than or equal to 18 mm and less than or equal to 24 mm, meeting the requirements of protection and smooth ventilation.

[0064] In some embodiments, the shape of the mesh hole 221 can also be circular. The size of the mesh hole 221 can be understood as the diameter size of the mesh hole 221. When the diameter size meets the conditions of being greater than or equal to 18 mm and less than or equal to 24 mm, it can not only have better protection performance and effectively block fingers or other objects from passing through the mesh hole 221, but also have better ventilation effect.

[0065] It should be noted that since the protective net 220 is constructed with multiple mesh bars 222 to form the mesh holes 221, the smaller the diameter of the mesh bar 222, the thinner the mesh bar 222, which will reduce the overall structural strength of the protective net 220; the larger the diameter of the mesh bar 222, the thicker the mesh bar 222, although it has higher structural strength, it will hinder the air flow and reduce the air outlet effect of the air outlet 120. Therefore, in the embodiments, it is necessary to optimize the size of the mesh bars 222 of the protective net 220 to avoid the diameter of the mesh body being too large or too small. Specifically, the diameter value range of the mesh bars 222 is 0.5 mm to 1 mm, meeting the strength requirements of the protective net 220 and having less impact on the air outlet of the air outlet 120.

[0066] Refer to Figure 4 As shown, taking Figure 4 the shown protective net 220 as an example for illustration, the diameter of the mesh bar 222 is D. When the diameter D of the mesh bar 222 is less than 0.5 mm, it means that the mesh bar 222 is too thin, reducing the structural strength of the protective net 220; when the diameter D of the mesh bar 222 is greater than 1 mm, it means that the mesh bar 222 is too thick, which will hinder the air outlet of the air outlet 120. Therefore, the value range of the diameter D of the mesh bar 222 is 0.5 mm to 1 mm, specifically it can be 0.5 mm, 0.8 mm or 1 mm, and the specific size can be selected according to the strength and air volume requirements of the protective net 220.

[0067] Refer to Figure 1 and Figure 2As shown, the panel 300 is provided with a wind deflector 330. The wind deflector 330 is rotatably connected to the air outlet 310, and the wind deflector 330 can open or close the air outlet 310. When the ceiling-mounted air conditioner 10 operates, the wind deflector 330 is opened, and air is sent into the room through the air outlet 310. When the ceiling-mounted air conditioner 10 stops operating, the wind deflector 330 is closed to play a role in dust prevention.

[0068] Referring to Figure 1 As shown, in some embodiments, the wind deflector 330 includes a cover plate 331 and a plurality of wind guide vanes 332 connected to the cover plate 331. The cover plate 331 is rotatably connected to the panel 300. The plurality of wind guide vanes 332 are arranged at intervals along the length direction of the cover plate 331 on the surface of the cover plate 331 to form a wind guiding structure. The plurality of wind guide vanes 332 can be inclined in different directions to meet the wind guiding requirements in different directions. This is only an example here. The wind guiding structure is not limited to the combination of the above-mentioned plurality of wind guide vanes 332. In some other embodiments, the wind deflector 330 can also be formed by arranging a plurality of wind guide strips, and specific selection can be made according to actual application requirements.

[0069] It can be understood that the wind deflector 330 not only plays a role in guiding the wind. When the wind deflector 330 is opened, since the wind guiding structure occupies a certain space at the air outlet 310, it can also play a role in blocking hands from reaching into the air supply channel.

[0070] Therefore, in the embodiment, the protection net 220 covers a part of the air outlet 120. When the wind deflector 330 is in the state of opening the air outlet 310, the wind deflector 330 can be located inside the air outlet 310 and opposite to the other part of the air outlet 120. That is to say, along the direction of the air outlet 310 towards the air outlet 120, the projection of the protection net 220 coincides with a part of the air outlet 120, and the projection of the wind deflector 330 coincides with the other part of the air outlet 120. During operation, the protection net 220 and the wind deflector 330 play a protective role at the same time. In this way, the protection net 220 does not need to completely cover the air outlet 120, the area of the protection net 220 can be reduced, the obstruction to the air outlet of the air outlet 120 can be reduced, and the requirements of both protection and ensuring smooth air outlet can be taken into account.

[0071] Referring to Figure 6 and Figure 7As shown, it can be understood that the air outlet 120 and the air supply outlet 310 are respectively arranged to extend along the width direction of the top-mounted air conditioner 10. The air outlet 120 and the air supply outlet 310 are generally rectangular in shape. The protective net 220 is arranged to extend along the length direction of the air outlet 120. The protective net 220 is rectangular, and the length of the protective net 220 is greater than or equal to the length of the air outlet 120, so that the protective net 220 covers the air outlet 120 in the length direction of the air outlet 120; the width of the protective net 220 is smaller than the width of the air outlet 120. In the width direction of the air outlet 120, the protective net 220 covers a part of the air outlet 120. When the air deflector 330 is in the state of opening the air supply outlet 310, the projection of the air deflector 330 covers another part of the air outlet 120, that is, when the air deflector 330 is opened, it is arranged along the width direction of the air outlet 120 with the protective net 220, and the layout is more reasonable. The cooperation of the protective net 220 and the air deflector 330 can play an effective protective role and ensure that the air outlet 120 has a better air outlet effect.

[0072] Referring to Figure 7 As shown, specifically, when the air deflector 330 is in the open state, the cover plate 331 rotates to a state close to being perpendicular to the plane where the air supply outlet 310 is located. A plurality of air deflector vanes 332 are arranged at intervals along the length direction of the air supply outlet 310 in the air supply outlet 310 to form an air guiding area 333. The air guiding area 333 and the protective net cooperate to cover the entire air outlet 120.

[0073] Figure 7 In the embodiment shown, the air guiding area 333 is located on one side of the air supply outlet 310. The air deflector vanes 332 are used to guide air in the air guiding area 333. Along the direction from the air supply outlet 310 towards the air outlet 120, the protective net 220 covers a part of the air outlet 120, and the air guiding area 333 can cover another part of the air outlet 120. Specifically, the projection of the air guiding area 333 and the projection of the protective net 220 can partially overlap, ensuring that the protective net 220 covers a part of the air outlet 120, and the projection of the air guiding area 333 covers another part of the air outlet 120.

[0074] In some embodiments, the projection of the air deflector 330 and the projection of the protective net 220 can be arranged to be close but not overlapping, meeting the requirement that the protective net 220 covers a part of the air outlet 120 and the air deflector 330 covers another part of the air outlet 120.

[0075] In a preferred embodiment, the projection of the protection net 220 covers half of the air outlet 120, and the air guiding area 333 covers the other half of the air outlet 120.
