Description

Technical Field

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

[0002] An air conditioner works by having the indoor unit absorb heat from the room and then transferring it to the outdoor unit for discharge through the compression or expansion of the refrigerant. The outdoor unit plays a crucial role as a component of the air conditioner. It typically uses a high-volume axial fan, with the condenser located on the air intake side of the fan. A fan cover is installed on the front panel of the outdoor unit corresponding to the air outlet of the axial fan. The fan cover protects the axial fan and prevents damage from foreign objects entering.

[0003] However, most front panels with fan covers have poor waterproofing. In rainy weather, rainwater can easily enter the indoor cavity of the outdoor unit through the ventilation holes of the fan cover, posing a safety hazard. Utility Model Content

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

Therefore, the example term "below" can include both upper and lower orientations.

[0046] 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, fan, condenser, and air outlet grille. The outdoor unit's fan generally uses a high-volume axial fan. The condenser is located on the air intake side of the outdoor fan, and a fan cover is installed on the front panel of the outdoor unit corresponding to the air outlet position of the axial fan. The fan cover protects the axial fan and prevents foreign objects from entering and damaging it.

[0047] However, most front panels with fan covers have poor waterproofing. In rainy weather, rainwater can easily enter the indoor cavity of the outdoor unit through the ventilation holes of the fan cover, posing a safety hazard.

[0048] like Figures 1-10 As shown, this utility model proposes a front panel assembly for installation on an outdoor unit 1, which can effectively solve the problem of poor waterproofing effect of the front panel 12 of the existing outdoor unit 1.

[0049] In terms of overall design, the front panel assembly includes a front panel 12 and an air outlet grille 20. The front panel 12 is provided with an air outlet 127 and a limiting recess 122 surrounding the air outlet 127. The air outlet grille 20 covers the air outlet 127 and is adapted to be embedded in the limiting recess 122. The air outlet grille 20 includes a cover body 21 and a frame 22. The frame 22 extends circumferentially along the cover body 21. The cover body 21 has a front surface and a rear surface arranged opposite to each other in a first direction Y. The frame 22 has a first end and a second end arranged opposite to each other in the first direction Y. The first end is connected to the front surface, and the second end abuts against the bottom surface of the limiting recess 122. The first end is closer to the central axis of the air outlet 127 than the second end.

[0050] Specifically, by placing the air outlet cover 20 over the air outlet 127 and embedding it in the limiting recess 122, the ease of installation of the air outlet cover 20 is improved. Moreover, the air outlet cover 20 has a frame 22 and a cover body 21. The first end of the frame 22 is connected to the front surface of the cover body 21, and the second end of the frame 22 can extend into the interior of the limiting recess 122 and abut against the bottom surface of the limiting recess 122. Since the first end is closer to the central axis of the air outlet 127 than the second end, the air outlet cover 20 can cooperate with the front panel 12 to form a roof-like structure after installation, thereby guiding rainwater and helping to reduce the amount of rainwater flowing into the body.

[0051] It is necessary to understand that, such as Figures 1-3As shown, the outdoor unit 1 includes a housing 10. An internal partition (not shown) divides the interior of the housing 10 into a first chamber and a second chamber. The first chamber houses a compressor and a four-way valve assembly. The second chamber houses a fan and a heat exchanger. In this embodiment, the housing 10 includes a front panel assembly, which comprises a front panel 12 and an air outlet grille 20. Specifically, the front panel 12 has an air outlet 127 that communicates with the interior of the outdoor unit 1. The air outlet 127 has a pipe extending into the housing 10, and the end of the pipe facing away from the front panel 12 is flared.

[0052] Still Figure 2 and Figure 3 As shown, a limiting recess 122 is provided on the side of the front panel 12 facing away from the interior of the housing 10. The limiting recess 122 is recessed towards the interior of the housing 10 and surrounds the air outlet 127. The aforementioned air outlet grille 20 is adapted to be embedded in the limiting recess 122 and connected to the bottom surface of the limiting recess 122. In this case, the air outlet grille 20 covers the outside of the air outlet 127.

[0053] The air outlet grille 20 includes a cover body 21 and a frame 22. Along the first direction Y, the cover body 21 has a front surface and a rear surface arranged opposite to each other, with the rear surface abutting against the bottom surface of the limiting recess 122. Simultaneously, along the first direction Y, the frame 22 has a first end and a second end arranged opposite to each other. The first end connects to the front surface, and the second end abuts against the bottom surface of the limiting recess 122, meaning the end face of the second end is on the same horizontal plane as the rear surface. The first end is closer to the central axis of the air outlet 127 than the second end. When the air outlet grille 20 is fitted into the limiting recess 122, the front panel 12, due to the limiting recess 122, can form a water-blocking flange 123 on the side of the frame 22 opposite to the cover body 21. This, combined with the frame 22, forms an eaves structure, thereby guiding rainwater and helping to prevent rainwater from flowing into the interior of the unit. In addition, the frame 22 extends circumferentially along the cover 21, which can improve the protection of the support column 202, reduce the damage of the external environment to the support column 202, and also improve the overall structural strength of the air outlet cover 20.

[0054] It should be noted that in this embodiment, the cover 21 is generally plate-shaped. 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.

[0055] Furthermore, the first direction Y mentioned above is the width direction of the outdoor unit 1. At this time, the side of the cover 21 facing the user (away from the outdoor unit 1) is the front surface, and the side of the cover 21 facing the outdoor unit 1 is the rear surface.

[0056] Because the existing assembly method between the front panel 12 and the air outlet grille 20 in the outdoor unit 1 of the air conditioner is adopted, it is easy to generate abnormal noise or squeaks due to vibration and collision. Especially when the outdoor unit 1 is under improper installation conditions such as tilting, the vibration of the front panel 12 is easily amplified.

[0057] It is important to further understand that multiple support protrusions 24 are spaced apart on the end face of the second end, and the support protrusions 24 abut against the bottom surface of the limiting platform 122. By providing support protrusions 24 on the end face of the second end, the contact area between the front panel 12 and the air outlet grille 20 can be effectively reduced, thereby reducing the transmission of vibration and the generation of abnormal noise. In this embodiment, the cover 21 is generally set as a square structure. At this time, the cover 21 has four side frames 22, and each side frame 22 is provided with multiple support protrusions 24, which are spaced apart. Since the second end of the side frame 22 is used to abut against the bottom surface of the limiting platform 122, the multiple support protrusions 24 can effectively reduce the contact area between the front panel 12 and the air outlet grille 20, thereby reducing the transmission of vibration and the generation of abnormal noise; in addition, the support protrusions 24 can also play a certain degree of buffering role or absorb some vibration through their own deformation, further reducing the vibration transmission of the front panel 12.

[0058] In this embodiment, the bottom surfaces of the cover 21 and the limiting platform 122 are spaced apart along the first direction Y. This arrangement helps to create an air outlet gap between the air outlet grille 20 and the front panel 12, which is beneficial for air outlet. Optionally, by providing a support protrusion 24 on the frame 22, the bottom surfaces of the cover 21 and the limiting platform 122 can be spaced apart. Alternatively, the second end of the frame 22 can be located on the side of the cover 21 facing the front panel 12, which also creates an air outlet gap between the air outlet grille 20 and the front panel 12.

[0059] It should be noted that when the cover 21 is configured with other structures, multiple support protrusions 24 can be set at equal intervals along the circumference of the frame 22, thereby ensuring the uniformity of the contact between the front panel 12 and the air outlet mesh cover 20.

[0060] In addition, an indicator 25 is provided on the side of the frame 22 away from the cover 21. In this embodiment, the indicator 25 is a raised structure, and the raised structure is arrow-shaped in general, so as to effectively improve the installation efficiency of the air outlet cover 20.

[0061] Furthermore, the cover 21 has a grille portion 211 and a mounting portion 212, with the mounting portion 212 located near the corner of the cover 21; the mounting portion 212 is provided with a first mounting hole 204, and the bottom surface of the limiting platform 122 is provided with four second mounting holes 124, with fasteners passing through the first mounting holes 204 and the second mounting holes 124 to connect the front panel 12 to the air outlet cover 20.

[0062] Specifically, by setting the grille 211, it can cooperate with the air outlet 127 of the front panel 12 to ensure the ventilation effect of the outdoor unit 1. At the same time, by setting the mounting part 212 at the four corners of the cover 21, the impact of the mounting part 212 on the ventilation of the outdoor unit 1 can be reduced. Moreover, the square cover 21 makes it easier to embed the air outlet cover 20, thereby helping to improve the assembly efficiency of the outdoor unit 1.

[0063] It should be understood that, in this embodiment, the cover 21 includes a central frame (not shown in the figure) and a surrounding panel (not shown in the figure). The central frame is cylindrical, and its front surface has an adhesive area where product logos, decorative layers, etc., can be pasted 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 the central frame. A ventilation channel is formed between the surrounding panel and the central frame, through which airflow can flow to the outside of the outdoor unit 1.

[0064] The cover 21 includes a grille portion 211 and a mounting portion 212, wherein the central frame and the surrounding panel are connected to form the grille portion 211 and the mounting portion 212. Optionally, the grille portion 211 is connected between the surrounding panel and the central frame, and the mounting portion 212 is disposed between the grille portion 211 and the surrounding panel. Figure 1 , Figure 2 , Figures 4 to 10 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.

[0065] In this embodiment, there are multiple mounting parts 212, and these mounting parts 212 are spaced apart circumferentially along the central frame. A first mounting hole 204 is provided on the rear surface of each mounting part 212, and the first mounting hole 204 communicates with the front surface of the mounting part 212. Simultaneously, four second mounting holes 124 are provided on the bottom surface of the limiting platform 122, and these four second mounting holes 124 are spaced apart with the axis of the air outlet channel as the center. In this case, the first mounting holes 204 correspond to the second mounting holes 124 of the front panel 12, and fasteners can pass through the first mounting holes 204 and be screwed into the second mounting holes 124, thereby achieving the connection and fixation between the air outlet grille 20 and the front panel 12.

[0066] It is 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. By placing the mounting parts 212 at the corners of the cover 21, the connection strength of the corners can be improved, thereby ensuring the structural strength of the air outlet mesh cover 20.

[0067] In this embodiment, the air outlet 127 has a circular structure, wherein the side length of the square structure is greater than the diameter of the air outlet 127. By setting the cover 21 to a square structure, making the air outlet 127 a circular structure, and making the side length of the square structure greater than the diameter of the air outlet 127, it is more conducive to air outlet.

[0068] It should be noted that the fastener can be a screw or stud, capable of passing through the first mounting hole 204 and being screwed into the second mounting hole 124. Of course, the fastener can also pass through the second mounting hole 124 and be screwed into the first mounting hole 204; no further restrictions are placed here.

[0069] Furthermore, the front surface of the mounting part 212 is provided with a clearance groove 201, and the rear surface of the mounting part 212 is provided with a support column 202. The end of the support column 202 facing away from the front surface is provided with a first mounting hole 204, and the first mounting hole 204 communicates with the clearance groove 201.

[0070] Specifically, by providing the clearance groove 201, fasteners can be effectively accommodated, thereby preventing rainwater flowing along the frame 22 from flowing to the fastener installation point, which can effectively reduce fastener corrosion and help improve the performance of the front panel 12.

[0071] It is necessary to understand that, such as Figures 6 to 9As shown, in this embodiment, the front surface of the mounting part 212 is provided with a clearance groove 201. The clearance groove 201 is configured as a near-triangular structure and has a first depth, which is at least greater than the thickness of the screw joint of the fastener. Simultaneously, the rear surface of the mounting part 212 is provided with a support column 202, which is positioned along the first direction Y, corresponding to the clearance groove 201. The support column 202 is used to abut against the bottom surface of the limiting countersunk platform 122. By providing the clearance groove 201 and the support column 202 in the mounting part 212, the mounting part 212 can have better structural strength. Since the mounting part 212 is located at the corner of the cover 21, it helps to further improve the connection strength of the corner, thereby ensuring the structural strength of the air outlet mesh cover 20.

[0072] It should be noted that the support column 202 can be set as a cylinder or a prism structure. At the same time, the support column 202 can also be set as a frustum to ensure the support effect of the support column 202 and thus improve the structural strength of the air outlet mesh cover 20.

[0073] 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.

[0074] 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.

[0075] It is necessary to understand that, such as Figures 6-9 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 20212.

[0076] like Figure 8 and Figure 9As 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.

[0077] 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 20212. Optionally, the radial cross-section of the receiving cavity 2021 is designed with a teardrop shape.

[0078] Furthermore, the outdoor unit 1 also includes a decorative element 23, which is adapted to be embedded in the clearance groove 201 to cover the first mounting hole 204.

[0079] Specifically, by setting decorative parts 23 in the clearance groove 201, on the one hand, it can reduce the backflow of rainwater into the receiving cavity 2021, thereby reducing the corrosion of the bolts, affecting the installation effect of the air outlet grille 20, and the convenience of subsequent maintenance and replacement of the air outlet grille 20; on the other hand, it can improve the aesthetics of the outdoor unit 1 and improve the user experience.

[0080] It is necessary to understand that, such as Figure 2 As shown, the outdoor unit 1 also includes a decorative component 23, which is fitted into the clearance groove 201.
