Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, specifically to an air outlet grille, an outdoor unit, and HVAC equipment. Background Technology

[0002] When assembling the air outlet grille of a traditional air conditioner outdoor unit with the whole unit, structural limitations can easily lead to difficulties in the installation and positioning of the air outlet grille. Therefore, most existing air outlet grilles are equipped with positioning structures to facilitate the pre-positioning installation of the air outlet grille and the outdoor unit.

[0003] However, during transportation (handling), multiple air outlet covers need to be stacked. The positioning structure on the air outlet covers can easily cause them to tip over, wear and deform, thus affecting the pass rate of the air outlet covers. Utility Model Content

[0004] The purpose of this invention is to at least solve the problem of reduced pass rate in existing air outlet mesh covers due to the installation of positioning structures. This purpose is achieved through the following technical solution:

[0044] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0045] 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 mean including 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.

[0046] 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.

[0047] 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. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0048] Split-type air conditioners consist of an indoor unit and an outdoor unit. Typically, the indoor unit includes components such as an evaporator, fan, air filter, and heater. The outdoor unit mainly includes components such as the casing, compressor, condenser, and air outlet grille. Traditional outdoor unit air outlet grilles, due to structural limitations, often present difficulties in positioning during assembly with the main unit, making it impossible to achieve the standard installation position. Therefore, most existing air outlet grilles incorporate positioning structures to facilitate pre-positioning of the grille with the outdoor unit.

[0049] However, during transportation (handling), multiple air outlet covers with the above structure need to be stacked. The positioning structure makes it easy for the air outlet covers to tip over, wear and deform, which in turn affects the pass rate of the air outlet covers.

[0050] like Figures 1-9 As shown, this utility model proposes an air outlet grille 20, which is used to install on the outdoor unit 1, so as to effectively solve the problem of reduced pass rate of existing air outlet grilles 20 due to the setting of positioning structure.

[0051] In terms of overall design, the air outlet grille 20 includes a cover body 21, a support column 202, and a positioning member 203. The cover body 21 has a front surface and a rear surface arranged opposite to each other along a first direction Y. The front surface has a clearance groove 201. The support column 202 is disposed on the rear surface of the cover body 21, and along the first direction Y, the support column 202 corresponds to the clearance groove 201. The support column 202 is used to connect to the outdoor unit 1. The positioning member 203 is disposed at the end of the support column 202 opposite to the front surface, and along the first direction Y, the length of the positioning member 203 is less than or equal to the depth of the clearance groove 201.

[0052] Specifically, by setting a positioning element 203 on the support column 202, the hood 21 can be pre-inserted into the outdoor unit 1 during connection and installation, thus achieving pre-positioning installation and helping to ensure the convenience of installing the air outlet grille 20. At the same time, by setting a clearance groove 201 on the hood 21, and setting the clearance groove 201 and the positioning element 203 on opposite sides of the hood 21 respectively, the positioning element 203 can be accommodated in the clearance groove 201 of the adjacent air outlet grille 20 during transportation (stacking), which can prevent the air outlet grille 20 from being worn and deformed. Moreover, the stacked air outlet grilles 20 are not easy to tip over, which helps to improve the reliability of transporting the air outlet grille 20. Thus, the air outlet grille 20 has both a positioning function and can reduce wear and deformation when stacked.

[0053] It is necessary to understand that, such as Figure 1 As shown, the outdoor unit 1 includes a housing 10. The housing 10 includes a front panel 12, on which the aforementioned air outlet grille 20 is mounted. The front panel 12 has a second mounting hole 124 and a positioning hole 125. The air outlet grille 20 includes a cover 21, a support column 202, and a positioning element 203. In this embodiment, the cover 21 has a plate-like structure. Optionally, the cover 21 can be constructed into various shapes, such as circular, rectangular, square, triangular, etc., and its specific shape can be determined according to the specific structure of the outdoor unit 1.

[0054] In this embodiment, the cover 21 includes a central frame (not shown) and a surrounding panel (not shown). The central frame is cylindrical, and its front surface has an adhesive area where product logos, decorative layers, etc., can be affixed to improve the visibility of the air outlet cover 20. The surrounding panel is fitted onto the outer periphery of the central frame and is connected to it. A ventilation channel is formed between the surrounding panel and the central frame, through which airflow can exit to the outside of the outdoor unit 1.

[0055] It should be noted that the first direction Y is the width direction of the outdoor unit 1. In this case, the side of the center frame facing the user (away from the outdoor unit 1) is the front surface, and the side of the center frame facing the outdoor unit 1 is the rear surface. Correspondingly, along the width direction of the outdoor unit 1, the cover 21 has a front surface and a rear surface arranged in opposite directions. The front surface is the side of the cover 21 away from the outdoor unit 1, and the rear surface is the side of the cover 21 facing the outdoor unit 1.

[0056] It needs to be further understood that the cover 21 has a grille portion 211 and a mounting portion 212, wherein the grille portion 211 is connected and disposed between the surrounding panel and the central frame, and the mounting portion 212 is disposed between the grille portion 211 and the surrounding panel. Figures 1-8 As shown, the grille section 211 includes multiple annular air guide strips and multiple curved air guide strips. The annular air guide strips are spaced apart around the axis of the central frame, and the curved air guide strips intersect with the annular air guide strips and are spaced apart circumferentially along the central frame. The angle between the guiding surface of each curved air guide strip and the axis of the frame 22 gradually increases from the center of the frame 22 towards its edge. Optionally, the grille section 211 also includes multiple long air guide strips and multiple short air guide strips, which are staggered. One end of each long air guide strip is connected to the circumferential surface of the central frame, and the other end is connected to the surrounding panel.

[0057] Still Figures 1-4 As shown, there are multiple mounting parts 212, which are spaced apart circumferentially along the central frame. The front surface of each mounting part 212 has a clearance groove 201, and the rear surface has a support post 202 for abutting against the front panel 12. The end of the support post 202 facing away from the front surface has a first mounting hole 204, which corresponds to a second mounting hole 124 on the front panel 12, and communicates with the clearance groove 201. A screw can then pass through the first mounting hole 204 and be screwed into the second mounting hole 124, thereby achieving the connection and fixation between the air outlet grille 20 and the front panel 12.

[0058] The support column 202 is provided with a positioning element 203, which can be inserted into the front panel 12. That is, the positioning element 203 can be inserted into the positioning hole 125, thereby realizing the correspondence between the first mounting hole 204 and the second mounting hole 124, so as to facilitate the subsequent tightening and fixing of the screwed parts. Optionally, the positioning element 203 can be set as a cylindrical structure.

[0059] It should be noted that the positioning component 203 can also be configured with other structures, such as a square tube column structure or a triangular prism structure. Furthermore, the positioning component 203 can also be configured as a snap-fit ​​structure 221, so that it can be inserted into the positioning hole 125 and then connected and fixed to the front panel 12. Among these, the aforementioned round tube column structure provides good assembly results and effectively reduces the manufacturing difficulty of the air outlet grille 20.

[0060] In addition, the aforementioned positioning component 203, support column 202, cover 21, etc. are integrally formed structures, and the air outlet cover 20 is a plastic part. At this time, the air outlet cover 20 has good structural strength.

[0061] It needs to be further understood that the aforementioned cover 21 has a square structure, and in this case, the mounting parts 212 are arranged near the corners of the cover 21. That is, there are four mounting parts 212, and the four mounting parts 212 are respectively arranged at the four corners of the cover 21. In this embodiment, the cover 21 has a square structure, and in this case, the cover 21 has a centrally symmetrical structure. This arrangement facilitates the installation of the air outlet mesh cover 20 in any direction, so as to effectively improve the production efficiency of the workshop. Moreover, since the mounting parts 212 are provided with clearance grooves 201 and support columns 202, the mounting parts 212 have good structural strength. Placing the mounting parts 212 at the corners of the cover 21 can improve the connection strength of the corners, thereby ensuring the structural strength of the air outlet mesh cover 20.

[0062] Furthermore, the clearance groove 201 has a limiting sidewall 2011, the contour of which matches the contour of the outer peripheral surface of the positioning member 203.

[0063] Specifically, by setting a limiting sidewall 2011 and matching the outline of the limiting sidewall 2011 with the outline of the outer peripheral surface of the positioning member 203, it helps to improve the convenience and accuracy of stacking multiple air outlet screens 20. Due to the limiting effect of the limiting sidewall 2011, combined with the accommodation of the positioning member 203 by the relief groove 201, the reliability of the air outlet screens 20 when stacked can be effectively improved, and it is not easy to tip over. It also improves the protection of the positioning member 203, making it less likely to be damaged, which helps to improve the pass rate of the air outlet screens 20.

[0064] It is necessary to understand that, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in this embodiment, the clearance groove 201 is configured as a triangular structure, and the limiting sidewall 2011 is located at the corner of the clearance groove 201 away from the axis of the cover 21. Optionally, when multiple air outlet covers 20 are stacked, the outer peripheral surface of the positioning member 203 is in close contact with the wall surface of the limiting sidewall 2011. At the same time, since the length of the positioning member 203 is less than or equal to the depth of the clearance groove 201, the positioning member 203 will not abut against the bottom surface of the clearance groove 201, thereby forming a supporting connection.

[0065] Furthermore, the air outlet mesh cover 20 also includes a frame 22, which extends circumferentially along the cover body 21. Along the first direction Y, the height of the support column 202 is the same as the height of the frame 22.

[0066] Specifically, by setting a frame 22 and making the height of the frame 22 the same as the height of the support column 202, it helps to improve the contact effect between the air outlet cover 20 and the front panel 12. At the same time, by extending the frame 22 along the circumference of the cover 21, the protection effect of the support column 202 can be improved, the damage of the external environment to the support column 202 can be reduced, and the overall structural strength of the air outlet cover 20 can also be improved.

[0067] It is necessary to understand that, such as Figure 3 , Figure 4 and Figure 7 As shown, the support column 202 is connected to the surrounding panel, and the aforementioned frame 22 is connected to the front end of the surrounding panel and extends towards the rear end of the surrounding panel, which helps to improve the structural strength of the air outlet grille 20. Simultaneously, the frame 22 extends circumferentially along the cover 21, and the height of the frame 22 is the same as the height of the support column 202. Therefore, during the installation of the air outlet grille 20, the frame 22 and the support column 202 can simultaneously abut against the front panel 12, which helps to increase the contact area between the air outlet grille 20 and the front panel 12. Furthermore, the frame 22 effectively reduces the contact between the external environment and the support column 202, thereby protecting the support column 202.

[0068] In this embodiment, the frame 22 is angled to the surrounding panel, giving the frame 22 good variability so that it can be adapted and connected to the limiting recess 122 of the front panel 12. At the same time, after the air outlet cover 20 is installed and fixed, the frame 22 at the top of the air outlet cover 20, together with the edge of the limiting recess 122, can form a guide structure, which helps to reduce the flow of external rainwater into the connection between the air outlet cover 20 and the front panel 12, thereby improving the performance of the air outlet cover 20.

[0069] Furthermore, the support column 202 has a receiving cavity 2021. Along the first direction Y, one end of the receiving cavity 2021 communicates with the first mounting hole 204, and the other end of the receiving cavity 2021 communicates with the relief groove 201.

[0070] Specifically, by providing the receiving cavity 2021, the material cost of manufacturing the support column 202 can be reduced, and the receiving cavity 2021 can also be used to accommodate the screw connection, thereby avoiding the screw connection occupying the space of the clearance groove 201.

[0071] It is necessary to understand that, such as Figures 5-7 As shown, the front surface of the support column 202 is the bottom surface of the clearance groove 201, and the front surface of the support column 202 has a receiving cavity 2021 communicating with the clearance groove 201. That is, the bottom surface of the clearance groove 201 is recessed towards the back of the air outlet grille 20 to form the receiving cavity 2021. At this time, one end of the receiving cavity 2021 communicates with the first mounting hole 204, and the other end of the receiving cavity 2021 communicates with the clearance groove 201. This arrangement helps to reduce the manufacturing difficulty of the support column 202 and the manufacturing cost of the air outlet grille 20. In this embodiment, the receiving cavity 2021 has a side wall 20212 and a bottom wall 20211, wherein the side wall 20212 is arranged around the bottom wall 20211, and the bottom wall 20211 is provided with a first mounting hole 204. At this time, the screw can pass through the first mounting hole 204 and be screwed into the second mounting hole 124, thereby fixing the air outlet grille 20 to the front panel 12. Among them, the side wall 20212 is connected to the limiting side wall 2011.

[0072] like Figure 4 and Figure 7 As shown, a reinforcing groove (not shown in the figure) is provided on the side of the support column 202 away from the receiving cavity 2021. The reinforcing groove helps to improve the structural strength of the support column 202. At the same time, multiple connecting ribs are also provided on the outer peripheral surface of the support column 202. The support column 202 is connected to the bottom of the frame 22 and the mounting part 212 through multiple reinforcing ribs, so as to further improve the structural strength of the air outlet mesh cover 20.

[0073] It is important to further understand that the sidewall 20212 is designed with a sloping structure, meaning that the inner diameter of the receiving cavity 2021 gradually decreases from the front end of the cover 21 towards the rear end. This design helps to form a guiding structure, which in turn facilitates the installation of the screw-in components. In this embodiment, the receiving cavity 2021 is located on the side of the mounting portion 212 away from the axis of the cover 21 and is smoothly connected to the limiting sidewall 2011. Optionally, the radial cross-section of the receiving cavity 2021 is designed with a teardrop shape.

[0074] The second aspect of this utility model proposes an outdoor unit 1, such as... Figure 1 , Figure 2 , Figure 8 and Figure 9As shown, the outdoor unit 1 includes a front panel 12 and an air outlet grille 20. The front panel 12 has multiple second mounting holes 124 and multiple positioning holes 125. Each second mounting hole 124 and each positioning hole 125 forms a group, i.e., an assembly part. In this embodiment, the front panel 12 has four assembly parts, arranged in a rectangular array. The air outlet grille 20 is the aforementioned air outlet grille 20. The air outlet grille 20 has four mounting parts 212. A support column 202 is provided on the rear surface of each mounting part 212. Along the first direction Y, a positioning element 203 and a first mounting hole 204 are provided on the end face of the support column 202 facing away from the front surface. The positioning element 203 is suitable for insertion into the positioning hole 125, and at this time, the first mounting hole 204 and the second mounting hole 124 are correspondingly arranged.

[0075] Specifically, when connecting the air outlet grille 20 to the outdoor unit 1, the positioning part 203 of the air outlet grille 20 needs to be inserted into the outdoor unit 1 in advance to achieve pre-positioning installation. Then, the screws pass through the first mounting hole 204 and the second mounting hole 124 to achieve the connection and fixation between the air outlet grille 20 and the outdoor unit 1. This setting helps to ensure the convenience of installing the air outlet grille 20.

[0076] Furthermore, since the cover 21 is provided with a clearance groove 201, and the clearance groove 201 and the positioning member 203 are respectively set on opposite sides of the cover 21, the positioning member 203 can be accommodated in the clearance groove 201 of the adjacent air outlet cover 20 during transportation (stacking). This can prevent the air outlet cover 20 from being worn and deformed, and the stacked air outlet cover 20 is not easy to tip over, which helps to improve the reliability of the air outlet cover 20 during transportation. Thus, the air outlet cover 20 has both a positioning function and can reduce wear and deformation when the air outlet cover 20 is stacked.

[0077] What needs further understanding is, such as Figure 2 As shown, a limiting recess 122 is provided on the front panel 12, and the air outlet grille 20 is adapted to be embedded in the limiting recess 122. By providing the limiting recess 122, the ease of installation of the air outlet grille 20 is further improved. Moreover, the use of a square air outlet grille 20 facilitates installation of the air outlet grille 20 in any direction, thereby improving workshop production efficiency. Furthermore, the setting of the limiting recess 122, together with the aforementioned frame 22, can form an eaves structure, which helps prevent rainwater from flowing back into the interior of the outdoor unit 1.

[0078] like Figure 2 and Figure 8As shown, further, the bottom surface of the limiting platform 122 is provided with a mounting hole 126, and the air outlet grille 20 has a frame 22. A snap-fit ​​structure 221 is provided on the side of the frame 22 facing the front panel 12. The snap-fit ​​structure 221 is adapted to be installed in the mounting hole 126. Specifically, the snap-fit ​​structure 221 is provided on the side of the frame 22 facing the front panel 12. The snap-fit ​​structure 221 extends in a direction perpendicular to the front panel 12, and at least a portion of the snap-fit ​​structure 221 extends into the mounting hole 126. Optionally, the snap-fit ​​structure 221 and the mounting hole 126 are interference fit, which helps to improve the reliability of the fit between the cover 21 and the front panel 12, so that the cover 21 can be stably installed at the ventilation opening of the front panel 12. This can, to a certain extent, prevent the cover 21 from shifting relative to the front panel 12 during the operation of the outdoor unit 1, thereby improving the structural reliability of the air outlet grille 20.

[0079] In this embodiment, there are four snap-fit ​​structures 221, and the four snap-fit ​​structures 221 are arranged at intervals along the circumference of the cover 21, that is, the four snap-fit ​​structures 221 are respectively arranged on the four sides of the air outlet grille 20.
