Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically providing a top cover assembly and a portable air conditioner. Background Technology

[0002] Currently, both wall-mounted and floor-standing air conditioners require fixed installation in a limited location and cannot be moved. Therefore, portable air conditioners have emerged. A portable air conditioner mainly consists of a casing, an indoor airflow assembly, and an outdoor airflow assembly. Both the indoor and outdoor airflow assemblies are housed within the casing. The casing has indoor air inlets and outlets corresponding to the indoor airflow assembly, and similarly, outdoor air inlets and outlets corresponding to the outdoor airflow assembly. Due to their small size, portable air conditioners can be moved to different locations or rooms to regulate the air temperature in those locations or rooms.

[0003] In portable air conditioners using related technologies, a deflector is installed on the top cover to guide the airflow. However, the deflector is usually a single-plate structure, and its limited rotation angle results in a limited airflow range. Furthermore, the fact that the airflow can only flow along one side of the windward side reduces the air volume. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problems of small air supply range and small air volume of the air outlet of the portable air conditioner.

[0005] In a first aspect, this utility model provides a top cover assembly for use in a portable air conditioner. The top cover assembly includes: a top cover plate with an indoor air outlet; and an air outlet grille detachably arranged at the indoor air outlet. The air outlet grille includes a first grille strip and a second grille strip that are cross-connected. The first grille strip extends circumferentially along the indoor air outlet and is arranged radially at intervals along the indoor air outlet. The second grille strip extends radially along the indoor air outlet and is fixedly connected to the first grille strip. The first grille strip is arranged inclined from the inside to the outside along the air outlet direction.

[0006] When the above technical solution is adopted, an air outlet grille is installed at the indoor air outlet. The air outlet grille is composed of a first grille bar and a second grille bar that are intersected and connected. This avoids obstruction of the airflow and increases the air delivery range and volume. By setting the first grille bar to be inclined upwards from the inside out, it is beneficial to further increase the air delivery range. At the same time, the air outlet grille can optimize the distribution of the airflow and improve the uniformity of the airflow, thereby improving the comfort of the airflow.

[0007] In an optional embodiment of the above-mentioned top cover assembly, the angle between the first grille strip and the plane where the top cover plate is located is α, and the angle of α ranges from 5° to 85°.

[0008] This design helps to further ensure the airflow range of the air outlet grille.

[0009] In an optional embodiment of the above-described top cover assembly, the inclination angles of the plurality of first grille strips are the same; or, along the radial direction of the indoor air outlet from the outside to the inside, the inclination angles of the plurality of first grille strips increase.

[0010] By setting the same tilt angle for the first grille strips, the uniformity of the airflow is improved. Along the radial direction of the indoor air outlet, the tilt angle of the first grille strips increases from the outside to the inside. This helps to concentrate the airflow near the interior, reduce airflow diffusion, and improve air delivery efficiency. Simultaneously, the angle of the outer first grille strips decreases, which helps to expand the coverage area of ​​the airflow and reduce blind spots.

[0011] In an optional embodiment of the above-mentioned top cover assembly, a connecting plate is provided in the middle of the air outlet grille, the connecting plate being arranged coaxially with the first grille strip and fixedly connected to the second grille strip.

[0012] By setting the connecting plate, a stable connection structure can be formed between it and the first and second grid bars, dispersing stress concentration points and improving structural stability.

[0013] In an optional embodiment of the above-mentioned top cover assembly, a connecting ring is provided on the outer periphery of the air outlet grille. The connecting ring is configured to be detachably connected to the top cover plate. The connecting ring is arranged coaxially with the first grille strip and fixedly connected to the second grille strip.

[0014] The connecting ring allows for a detachable connection between the air outlet grille and the top cover, facilitating installation and disassembly. Simultaneously, the connecting ring forms a stable connection structure with the first and second grille bars, dispersing stress concentration points and enhancing structural stability.

[0015] In an optional embodiment of the above-described top cover assembly, the distance between the upper end face of the plurality of first grille strips and the upper end face of the connecting ring increases radially from the outside to the inside along the indoor air outlet.

[0016] This configuration allows for higher airflow speeds near the center, reducing airflow loss.

[0017] In an optional embodiment of the above-mentioned top cover assembly, the lower end face of the first grille bar is provided with an inclined guide side.

[0018] The airflow guides the airflow, helping to direct airflow into the channel between adjacent first grille bars, thereby increasing the air intake volume of the air outlet grille.

[0019] In an optional embodiment of the above-described top cover assembly, the spacing between adjacent first grille bars is equal; and / or, the included angle between adjacent second grille bars is equal.

[0020] This arrangement helps improve the uniformity of airflow through the air outlet grille, avoiding problems such as excessively high local wind speeds or dead air zones; at the same time, it helps improve the structural stability of the air outlet grille, preventing deformation or damage caused by uneven stress.

[0021] In an optional embodiment of the above-mentioned top cover assembly, the first grille strip and the second grille strip are integrally formed.

[0022] By integrally molding the first and second grille bars, a uniform stress distribution can be formed, improving the structural strength of the air outlet grille and reducing production costs.

[0023] Secondly, this utility model provides a portable air conditioner, comprising: a housing, which at least defines an indoor heat exchange chamber inside, and the housing is provided with an indoor air inlet for the indoor heat exchange chamber; an indoor heat exchanger disposed in the indoor heat exchange chamber; and a top cover assembly as described above, the top cover assembly being disposed at the top of the housing, and the indoor air outlet communicating with the indoor heat exchange chamber.

[0024] When adopting the above technical solution, by installing an air outlet grille at the indoor air outlet, the air outlet grille is composed of a first grille bar and a second grille bar that are cross-connected. This avoids obstructing the airflow after it enters the indoor heat exchange chamber through the indoor air inlet and exchanges heat with the indoor heat exchanger, thereby increasing the air delivery range and air volume. Simultaneously, the air outlet grille optimizes the distribution of the airflow through diversion and dispersion, improving the uniformity of the airflow and thus enhancing the comfort of the airflow.

[0043] Firstly, combining Figures 1 to 8 As shown, this utility model provides a top cover assembly for use in portable air conditioners. The top cover assembly includes a top cover plate 100 and an air outlet grille 200.

[0044] An indoor air outlet 110 is provided on the top cover plate 100. An air outlet grille 200 is detachably arranged on the indoor air outlet 110. The air outlet grille 200 includes a first grille bar 210 and a second grille bar 220 that are cross-connected. The first grille bar 210 extends circumferentially along the indoor air outlet 110 and is arranged radially at intervals along the indoor air outlet 110. The second grille bar 220 extends radially along the indoor air outlet 110 and is fixedly connected to the first grille bar 210. The first grille bar 210 is arranged inclined from the inside to the outside along the air outlet direction.

[0045] Optionally, the indoor air outlet 110 is located in the middle of the top cover plate 100, that is, the indoor air outlet 110 and the top cover plate 100 are arranged coaxially. In this way, the structural strength of the top cover plate 100 and the uniformity of stress distribution can be improved.

[0046] Optionally, the air outlet grille 200 is detachably mounted on the indoor air outlet 110. For example, the air outlet grille 200 is connected to the top cover plate 100 by one or more of the following methods: snap-fit, screw connection, adhesive, riveting, plug-in connection, etc.

[0047] Optionally, the indoor air outlet 110 is configured as a circular opening. A circular opening has no right-angle dead corners, which can more effectively guide airflow and push the air evenly to all sides, and dust is less likely to adhere.

[0048] Alternatively, the indoor air outlet 110 can be configured as an opening in the shape of a square, polygon, or other shapes.

[0049] Optionally, the outline shape of the first grille strip 210 is consistent with the outline shape of the indoor air outlet 110. The first grille strip 210 extends along the axis of the indoor air outlet 110 to form a shape consistent with the outline of the indoor air outlet 110, thereby enabling the air outlet grille 200 to match the indoor air outlet 110. Further, multiple first grille strips 210 are arranged radially spaced along the indoor air outlet 110. In this way, an airflow channel can be formed between adjacent first grille strips 210. The airflow can be dispersed through the airflow channel and guided through the surface of the first grille strip 210, thereby enabling the air in the portable air conditioner to be dispersed into the indoor environment, since the air outlet grille 200 does not obstruct or block the airflow. Therefore, this solution can improve the air delivery range and air volume of the air outlet while ensuring the uniformity of the airflow.

[0050] Optionally, the first grille strip 210 is arranged inclined from the inside out along the air outlet direction. Specifically, "from the inside out" refers to the direction from the center of the indoor air outlet 110 to the outer perimeter. The first grille strip 210 being inclined from the inside out along the air outlet direction can be understood as the first grille strip 210 being inclined outward from the bottom to the top. In this way, air can be further guided along the surface of the inclined first grille strip 210. The air delivery angle of the first grille strip 210 is wider, therefore, the air delivery range of the first grille strip 210 is larger, which can make the indoor temperature more uniform.

[0051] Optionally, the surface of the first grid bar 210 may be provided with a plurality of spaced-apart guide bars or guide ribs. The guide ribs extend along the height direction of the first grid bar 210 and are provided on the sides of adjacent first grid bars 210 facing each other.

[0052] Alternatively, adjacent first grille bars 210 have multiple spaced protrusions on their sides facing each other, the protrusions being used to guide and disperse airflow.

[0053] Optionally, the air outlet grille 200 further includes a second grille strip 220. The second grille strip 220 extends radially along the indoor air outlet 110 and is fixedly connected to a plurality of first grille strips 210. This ensures the structural stability of the air outlet grille 200. Optionally, multiple second grille strips 220 are provided and arranged circumferentially around the indoor air outlet 110.

[0054] Optionally, the top cover assembly is used in a portable air conditioner. The portable air conditioner includes a housing and a base, with the top cover assembly, housing, and base collectively enclosing a cavity. The cavity is constructed as an independent indoor heat exchange cavity and an outdoor heat exchange cavity. In this design, the indoor and outdoor heat exchange cavities are positioned at their upper limits, and the top cover assembly is located at the top of the housing and correspondingly arranged with the indoor heat exchange cavity. This allows for the guidance of airflow from the indoor heat exchange cavity.

[0055] When adopting the above technical solution, an air outlet grille 200 is installed at the indoor air outlet 110. The air outlet grille 200 is formed by the cross connection of a first grille bar 210 and a second grille bar 220. By setting the first grille bar 210 to be inclined upwards from the inside to the outside along the air outlet direction, it is beneficial to further improve the air delivery range of the air outlet. In this way, it is possible to avoid obstructing the air outlet airflow and improve the air delivery range and air volume. At the same time, the air outlet grille 200 can optimize the distribution of the air outlet airflow through diversion and dispersion, improve the uniformity of the air outlet airflow, and thus improve the comfort of the air outlet airflow.

[0056] In an optional embodiment of the above-mentioned top cover assembly, the angle between the first grille strip 210 and the plane of the top cover plate 100 is α, and the angle α ranges from 5° to 85°.

[0057] This configuration, with the first grille bar 210 tilted upwards from the inside out, helps to further ensure the airflow range.

[0058] Preferably, α is 60°. Alternatively, α can be other angles.

[0059] In an optional embodiment of the above-mentioned top cover assembly, the inclination angles of the plurality of first grille bars 210 are the same; or, along the radial direction of the indoor air outlet 110 from the outside to the inside, the inclination angles of the plurality of first grille bars 210 increase.

[0060] By setting the same tilt angle for the first grille strip 210, it is beneficial to improve the uniformity of the airflow.

[0061] By setting the first grille bar 210 to have an increasingly larger tilt angle from the outside to the inside along the radial direction of the indoor air outlet 110, it helps to concentrate the airflow close to the inside, reduce airflow diffusion, and improve air supply efficiency; at the same time, the angle of the first grille bar 210 on the outside becomes smaller, which helps to cover the area of ​​the excessive airflow and reduce air supply blind spots.

[0062] In an optional embodiment of the above-mentioned top cover assembly, a connecting plate 230 is provided in the middle of the air outlet grille 200. The connecting plate 230 is coaxially arranged with the first grille bar 210 and fixedly connected to the second grille bar 220.

[0063] By setting the connecting plate 230, a stable connection structure can be formed between it and the first grid bar 210 and the second grid bar 220, which can disperse stress concentration points and improve structural stability.

[0064] In addition, this arrangement can concentrate the airflow near the connecting plate 230, reduce eddy current loss, and minimize losses.

[0065] Alternatively, connection plate 230 may not be provided.

[0066] In an optional embodiment of the above-mentioned top cover assembly, the outer periphery of the air outlet grille 200 is provided with a connecting ring 240, which is configured to be detachably connected to the top cover plate 110. The connecting ring 110 is coaxially arranged with the first grille strip 210 and fixedly connected to the second grille strip 220.

[0067] By setting the connecting ring 240, the air outlet grille 200 and the top cover plate 110 can be detachably connected, which is convenient for installation and disassembly; at the same time, the connecting ring 240 can form a stable connection structure with the first grille bar 210 and the second grille bar 220, dispersing stress concentration points and improving structural stability.

[0068] Optionally, the connecting ring 240 is detachably connected to the top cover plate 100. Specifically, the connection is made by means of snap-fit, welding, plugging, riveting, etc.

[0069] In an optional embodiment of the above-mentioned top cover assembly, the distance between the upper end face of the plurality of first grille strips 210 and the upper end face of the connecting ring 240 increases from the outside to the inside along the radial direction of the indoor air outlet 110.

[0070] This configuration allows for higher airflow velocity between the first grille bars 210 near the center, reducing airflow loss.

[0071] Alternatively, the upper end face of the plurality of first grid strips 210 is equidistant from the upper end face of the connecting ring 240.

[0072] It should be noted that the upper end face of the first grille strip 210 and the upper end face of the connecting ring 240 are both facing the indoor environment.

[0073] In an optional embodiment of the above-mentioned top cover assembly, the lower end face of the first grille bar 210 is provided with an inclined guide side 211.

[0074] Optionally, the first grille bar 210 includes two opposing sides, both of which face the adjacent first grille bar 210. A guide side 211 slopes upward from the bottom end of one of the sides to connect with the other side.

[0075] The airflow guide side 211 can guide the flow of air, helping to guide the air to flow into the channel between adjacent first grille bars, thereby increasing the air intake volume of the air outlet grille.

[0076] Alternatively, the flow guide side 211 may not be provided.

[0077] It should be noted that the lower end face of the first grille strip 210 is arranged opposite to the upper end face. When the top cover assembly is used in a portable air conditioner, the lower end face of the first grille strip 210 faces the indoor heat exchange chamber.

[0078] In an optional embodiment of the above-described top cover assembly, the spacing between adjacent first grille bars 210 is equal; and / or, the included angle between adjacent second grille bars 220 is equal.

[0079] This arrangement helps to improve the uniformity of airflow through the air outlet grille 200, avoiding problems such as excessively high local wind speeds or dead air zones; at the same time, it helps to improve the structural stability of the air outlet grille, preventing deformation or damage caused by uneven stress.

[0080] Specifically, the spacing between adjacent first grille bars 210 is equal, and the included angle between adjacent second grille bars 220 is equal. This ensures a more uniform airflow through the exhaust grille 200 and makes the structure of the exhaust grille 200 more stable.

[0081] Alternatively, the spacing between adjacent first grille bars 210 may be unequal, which can be determined by the designer according to actual needs or actual air volume; the included angle between adjacent second grille bars 220 may be equal.

[0082] Alternatively, the spacing between adjacent first grid bars 210 is equal; the included angle between adjacent second grid bars 220 is not equal.

[0083] In an optional embodiment of the above-mentioned top cover assembly, the first grille strip 210 and the second grille strip 220 are integrally formed.

[0084] By integrally molding the first grille bar 210 and the second grille bar 220, a uniform stress distribution can be formed, improving the structural strength of the air outlet grille 200 and reducing production costs.

[0085] Alternatively, the first grid strip 210 and the second grid strip 220 can be connected by welding, gluing, or other methods.

[0086] Secondly, this utility model provides a portable air conditioner, including a housing 10, an indoor heat exchanger 20, and a top cover assembly as described above. The housing 10 at least defines an indoor heat exchange chamber 11, and the housing 10 is provided with an indoor air inlet for the indoor heat exchange chamber 11. The indoor heat exchanger 20 is disposed in the indoor heat exchange chamber 11. The top cover assembly as described above is disposed at the top of the housing 10, and an indoor air outlet 110 communicates with the indoor heat exchange chamber 11.

[0087] When the above technical solution is adopted, an air outlet grille 200 is installed at the indoor air outlet 110. The air outlet grille 200 is composed of a first grille bar 210 and a second grille bar 220 that are cross-connected. In this way, the obstruction of the airflow entering the indoor heat exchange chamber 11 through the indoor air inlet and exchanging heat with the indoor heat exchanger 20 can be avoided, thereby improving the air supply range and air volume. At the same time, the air outlet grille 200 can optimize the distribution of the airflow and improve the uniformity of the airflow, thereby improving the comfort of the airflow.

[0088] Optionally, an indoor fan 30 is provided in the indoor heat exchange chamber 11. The indoor fan 30 is arranged coaxially with the indoor air outlet 110 to improve the uniformity and smoothness of the airflow.

[0089] Alternatively, the indoor fan 30 can also be other types of fans.

[0090] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings.
