Description

Technical Field

[0001] This application belongs to the field of HVAC equipment technology, specifically relating to a panel assembly, an outdoor HVAC unit, and HVAC equipment. Background Technology

[0002] HVAC equipment includes outdoor units and indoor units. Outdoor units are typically installed outdoors and include a casing and heat exchange components and a fan housed within it. The casing usually has an air outlet, and an air outlet grille needs to be installed on the outside of the outlet.

[0003] In related technologies, conventionally designed air outlet grilles are usually composed of several horizontal and vertical grilles. To ensure ventilation efficiency, the grille spacing is usually set to be large, resulting in the entire air outlet grille not only having low rigidity and being easy to deform, but also being unsightly. Utility Model Content

[0004] The purpose of this application is to at least solve the problems of conventionally designed air outlet grilles having low rigidity, being prone to deformation, and being unsightly. This purpose is achieved through the following methods:

[0009] Multiple second connecting ribs are arranged in multiple rows along the first direction, with a row of second connecting ribs between two adjacent rows of first connecting ribs. The multiple second connecting ribs in each row are connected sequentially along the second direction. Along the second direction, the multiple second connecting ribs in each row are staggered from the multiple first connecting ribs in each row, and both ends of each second connecting rib are connected to two adjacent second connecting ribs, thus defining multiple ventilation holes.

[0010] The auxiliary connecting ribs located within the ventilation holes are respectively connected to two adjacent second connecting ribs.

[0011] In some embodiments of this application, the first connecting rib, the second connecting rib, and the auxiliary connecting rib are all arc-shaped ribs, and the first connecting rib, the second connecting rib, and the auxiliary connecting rib all protrude from one side of the panel body along the first direction to the other side.

[0013] And / or, along the first direction, the distance between two adjacent first connecting ribs is set in the range of 15mm-30mm.

[0014] In some embodiments of this application, the area of ​​the first pore accounts for 1 / 5 to 1 / 3 of the area of ​​the ventilation hole.

[0015] In some embodiments of this application, the area of ​​each of the ventilation holes accounts for 0.14% to 0.42% of the area of ​​the ventilation opening.

[0016] In some embodiments of this application, along the first direction, the distance between the auxiliary connecting rib and the first connecting rib in each of the ventilation holes is less than 8.1 mm.

Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0035] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0036] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0037] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0038] This application provides an embodiment of a heating, ventilation, and air conditioning (HVAC) system, which can be used as a cooling or heating device such as a household air conditioner, central air conditioner, heat pump system, or multi-split system. The HVAC system includes an outdoor unit and an indoor unit connected to the outdoor unit via piping. The indoor unit is typically installed indoors, while the outdoor unit is typically installed outdoors. The indoor and outdoor units work together to achieve the functions of cooling, heating, dehumidification, and air purification, thereby achieving comfortable air quality.

[0039] When HVAC equipment is used as a central air conditioning system, there is usually one outdoor unit, while there can be multiple indoor units. Each indoor unit has one or more exhaust vents to discharge cooled, heated, dehumidified, or purified air into the room. The indoor units typically contain an indoor heat exchanger, and the outdoor units typically contain an outdoor heat exchanger. The indoor and outdoor heat exchangers are usually connected by refrigerant pipes, allowing refrigerant to flow between them. In the cooling process of HVAC equipment, the indoor heat exchanger acts as an evaporator. The refrigerant in the evaporator changes from a liquid state to a gaseous state, absorbing heat during evaporation. During this process, the evaporator exchanges heat with the air flowing through it, carrying away the heat from the air in the indoor unit. As a result, the air discharged from the indoor unit is cooled and released heat, causing the indoor unit to blow out cold air. Simultaneously, the outdoor heat exchanger acts as a condenser. The refrigerant in the condenser changes from a gaseous state to a liquid state, releasing heat during condensation. During this process, the condenser exchanges heat with the air flowing through it, carrying the heat from the condenser to the outside of the outdoor unit, thus achieving the cooling process. In the heating process of HVAC equipment, the outdoor heat exchanger acts as an evaporator. The refrigerant in the evaporator changes from a liquid state to a gaseous state, absorbing heat during evaporation. During this process, the evaporator exchanges heat with the air flowing through it, transferring the heat carried by the air in the outdoor unit to the refrigerant. Simultaneously, the indoor heat exchanger acts as a condenser. The refrigerant in the condenser changes from a gaseous state to a liquid state, releasing heat during condensation. During this process, the condenser exchanges heat with the air flowing through it, allowing the air in the indoor unit to carry away the heat carried by the condenser and discharge it into the room, thus blowing hot air from the indoor unit. This achieves the heating process.

[0040] According to some embodiments of this application, the HVAC outdoor unit proposed in this application further includes a housing and a panel assembly 10. The housing is provided with an air outlet, and the panel assembly 10 is disposed at the air outlet and has a ventilation opening corresponding to and connected to the air outlet.

[0041] The casing contains components such as an outdoor heat exchanger, compressor, and refrigerant piping.

[0042] For example, an air outlet is provided on the side of the housing.

[0043] Please see Figures 1 to 3According to some embodiments of this application, a panel assembly 10 is provided, including a panel body 11 and a mesh cover 12. The panel body 11 has ventilation openings; the mesh cover 12 is disposed on one side of the panel body 11 in the thickness direction and has a ventilation area covering the ventilation openings. The mesh cover 12 includes a plurality of first connecting ribs 121, a plurality of second connecting ribs 122, and a plurality of auxiliary connecting ribs 123. A plurality of fish-scale-shaped ventilation holes 124 are defined between the plurality of first connecting ribs 121 and the plurality of second connecting ribs 122. Each ventilation hole 124 located in the ventilation area is provided with an auxiliary connecting rib 123, which is configured to divide the ventilation hole 124 into a first gap 1241 and a second gap 1242.

[0044] For example, the panel body 11 is in any shape, such as square or rectangular.

[0045] For example, the ventilation openings on the panel body 11 can be any shape, such as round or square.

[0046] For example, the first connecting rib 121, the second connecting rib 122 and the auxiliary connecting rib 123 can be flat ribs or circular ribs.

[0047] Understandably, the fish scale shape is similar to a fan shape, but all three sides are curved.

[0048] The panel body 11 has a ventilation opening, which is connected to the air outlet of the casing to allow the HVAC outdoor unit to ventilate with the outside. By providing a mesh cover 12 on one side of the panel body 11 in the thickness direction, the mesh cover 12 has a ventilation area corresponding to the vent, and includes multiple first connecting ribs 121, multiple second connecting ribs 122, and multiple auxiliary connecting ribs 123. Among them, multiple fish-scale-shaped ventilation holes 124 are defined between the multiple first connecting ribs 121 and the multiple second connecting ribs 122. The multiple fish-scale-shaped ventilation holes 124 are not only more aesthetically pleasing, but also have high structural strength and good compressive and bending resistance, thereby helping to improve the overall rigidity of the mesh cover 12. Furthermore, by providing auxiliary connecting ribs 123 in each ventilation hole 124 located in the ventilation area, the overall rigidity of the mesh cover 12 can be further improved, making it less likely to break or be crushed in the ventilation area. Moreover, the auxiliary connecting ribs 123 can divide the ventilation hole 124 into a first gap 1241 and a second gap 1242, thereby reducing the entry of external objects such as fingers into the air outlet, thus improving the safety of using the mesh cover 12.

[0049] Please see Figures 1 to 3According to some embodiments of this application, multiple first connecting ribs 121 are arranged in multiple rows, and the multiple rows of first connecting ribs 121 are spaced apart along a first direction. The multiple first connecting ribs 121 arranged in each row are connected sequentially along a second direction. Both the first direction and the second direction are perpendicular to the thickness direction of the panel body 11, and the second direction is perpendicular to the first direction. Multiple second connecting ribs 122 are arranged in multiple rows along the first direction. A row of second connecting ribs 122 is arranged between two adjacent rows of first connecting ribs 121. The multiple second connecting ribs 122 arranged in each row are connected sequentially along the second direction. Along the second direction, the multiple second connecting ribs 122 arranged in each row are staggered from the multiple first connecting ribs 121 arranged in each row. The two ends of each second connecting rib 122 are respectively connected to two adjacent second connecting ribs 122, and multiple ventilation holes 124 are defined. The auxiliary connecting ribs 123 located in the ventilation holes 124 are respectively connected to two adjacent second connecting ribs 122.

[0050] Specifically, in each ventilation hole 124 located in the ventilation area, an auxiliary connecting rib 123 is connected to two adjacent second connecting ribs 122 to form a first gap 1241, and a second gap 1242 is formed between the auxiliary connecting rib 123, the first connecting rib 121, and the two adjacent second connecting ribs 122. The first gap 1241 is also fish-scale shaped.

[0051] Please see Figures 1 to 3 According to some embodiments of this application, the first connecting rib 121, the second connecting rib 122 and the auxiliary connecting rib 123 are all arc-shaped ribs, and the first connecting rib 121, the second connecting rib 122 and the auxiliary connecting rib 123 all protrude from one side of the panel body 11 along the first direction to the other side.

[0052] That is, the bending directions of the first connecting rib 121, the second connecting rib 122 and the auxiliary connecting rib 123 are the same, which makes the overall structure of the mesh cover 12 more regular and helps to improve the overall aesthetics of the product.

[0053] According to some embodiments of this application, along the second direction, the distance between the two ends of the first connecting rib 121 is set in the range of 60mm-90mm; along the first direction, the distance between two adjacent first connecting ribs 121 is set in the range of 15mm-30mm.

[0054] By adopting the above-described arrangement of the first connecting rib 121, the speed of gas flow through the ventilation hole 124 is increased, thereby increasing the ventilation volume through the ventilation hole 124 per unit time, which in turn helps to improve the ventilation efficiency of the mesh cover 12.

[0055] According to some embodiments of this application, the area of ​​the first pore 1241 is 1 / 5 to 1 / 3 of the area of ​​the ventilation hole 124.

[0056] Understandably, the area of ​​the second pore 1242 is within 2 / 3 to 4 / 5 of the area of ​​the ventilation hole 124, and the area of ​​the first pore 1241 is smaller than the area of ​​the second pore 1242. Furthermore, the area of ​​the first pore 1241 is relatively smaller than the area of ​​the entire ventilation hole 124. This allows the auxiliary connecting rib 123 to help reduce the impact on the ventilation efficiency of the ventilation hole 124 while ensuring the safety of the mesh cover 12 in using the ventilation hole 124 located in the ventilation area by dividing the ventilation hole 124 located in the ventilation area into the first pore 1241 and the second pore 1242.

[0057] According to some embodiments of this application, the area of ​​each ventilation hole 124 accounts for 0.14% to 0.42% of the area of ​​the ventilation opening.

[0058] That is, the area of ​​each ventilation hole 124 located in the ventilation area is relatively small compared to the area of ​​the entire ventilation opening, and the area of ​​each ventilation hole 124 is also relatively small. Without affecting the ventilation efficiency, this helps to reduce the risk of external objects accidentally touching and entering the ventilation hole 124.

[0059] According to some embodiments of this application, along the first direction, the distance between the auxiliary connecting rib 123 and the first connecting rib 121 in each ventilation hole 124 is less than 8.1 mm.

[0060] By setting the distance between the auxiliary connecting rib 123 located in each ventilation hole 124 and the first connecting rib 121 along the first direction to less than 8.1mm, the spacing between the auxiliary connecting rib 123 and the first connecting rib 121 is small, which can meet the requirements of European safety standards and other relevant regulations, reducing the risk of external objects accidentally touching and entering the ventilation opening through the second hole 1242, and helping to improve the safety of the mesh cover 12.

[0061] According to some embodiments of this application, the auxiliary connecting rib 123 is sized in the range of 1.5mm-2mm along the thickness direction of the panel body 11.

[0062] By setting the auxiliary connecting rib 123 in the thickness direction of the panel body 11 within the range of 1.5mm-2mm, the auxiliary connecting rib 123 can have good bending and compressive strength, which helps to improve the overall rigidity of the ventilation area of ​​the mesh cover 12, thereby improving the service life of the mesh cover 12.

[0063] Please see Figure 1 In some embodiments of this application, the mesh cover 12 further includes a circumferential connecting rib 125, which surrounds the periphery of a plurality of first connecting ribs 121 and a plurality of second connecting ribs 122.

[0064] The circumferential connecting ribs 125 are arranged around the periphery of the multiple ventilation holes 124 and are connected to the multiple first connecting ribs 121 and second connecting ribs 122 located at the edge of the mesh cover 12. They play a supporting and protective role, and help to further improve the crush-resistant performance of the mesh cover 12. They can also reduce the risk of the multiple first connecting ribs 121 and multiple second connecting ribs 122 located at the edge of the mesh cover 12 scratching the operators.

[0065] Please see Figure 2 According to some embodiments of this application, the panel body is provided with a first connection hole 111, and the housing of the HVAC outdoor unit is provided with a second connection hole. Fasteners can pass through the first connection hole 111 and the second connection hole to fix the panel assembly 10 to the housing of the HVAC outdoor unit.

[0066] For example, there are multiple first connection holes 111, which are spaced apart along the circumference of the panel body and are fixedly connected to the housing of the HVAC outdoor unit by multiple fasteners.

[0067] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
