Description

Technical Field

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

[0002] An air conditioner typically consists of two parts: an indoor unit and an outdoor unit. As the name suggests, the indoor unit is installed indoors, and the outdoor unit is installed outdoors. To protect the outdoor unit, it has a casing, making its internal structure less susceptible to damage. Specifically, the casing includes a top cover and side panels, which connect to form a cavity to house the internal structure of the outdoor unit.

[0003] When the compressor is running, it causes slight vibrations in the outdoor unit casing. Over time, these slight vibrations can cause minor collisions between the top cover and side panels, leading to scratches and paint chipping. In outdoor environments exposed to wind and rain, these scratched and chipped areas are prone to corrosion, affecting the lifespan of the outdoor unit. Furthermore, scratches and paint chipping are also common during transportation. Utility Model Content

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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 the outdoor unit itself. The outdoor unit's casing includes a top cover and side panels, which connect to form a cavity to house the other components of the outdoor unit.

[0042] However, when the compressor is running, it causes slight vibrations in the outdoor unit casing. Over time, these slight vibrations can lead to minor collisions between the top cover and side panels, resulting in scratches and paint peeling. In outdoor environments exposed to wind and rain, these scratched and peeled areas are prone to corrosion, affecting the lifespan of the outdoor unit. Furthermore, scratches and paint peeling are also common during transportation.

[0043] like Figures 1-6 As shown, the first aspect of this utility model proposes an outdoor unit 1 to solve the problem that existing outdoor units 1 are prone to scratches and paint peeling.

[0044] In terms of overall design, the outdoor unit 1 includes a top cover 14 and a surrounding panel assembly 100. The top cover 14 has a top plate portion 141 and a side plate portion 142 connected to the top plate portion 141. The top of the surrounding panel assembly 100 is sequentially provided with a bending portion 101, a support portion 102, and a folded edge portion 103. The support portion 102 is connected to the side plate portion 142. A first gap exists between the end of the side plate portion 142 facing away from the top plate portion 141 and the bending portion 101, and a second gap exists between the top plate portion 141 and the folded edge portion 103.

[0045] Specifically, by providing a bending portion 101 and a folded edge portion 103 on the top of the enclosure assembly 100, and ensuring that the bending portion 101 and the side plate portion 142, and the folded edge portion 103 and the top plate portion 141 are all clearance fits, the contact area between the enclosure assembly 100 and the top cover 14 can be effectively reduced. This avoids paint wear or even peeling of the enclosure assembly 100 or the top cover 14 due to the operation of the compressor or the handling of the whole unit, and helps to solve the problem of scratches and paint peeling that easily occur in the existing outdoor unit 1 during use.

[0046] It is necessary to understand that, such as Figure 1 As shown, the outdoor unit 1 includes a housing. The housing includes a top cover 14, a surrounding panel assembly 100, and a chassis assembly, with the top cover 14 and chassis assembly respectively connected to opposite sides of the surrounding panel assembly 100. An internal partition (not shown) divides the housing's interior space 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 motor and a heat exchanger. The internal structure of the housing is not shown in the figure.

[0047] Combination Figures 3-6 As shown, the top cover 14 includes a top plate portion 141 and a side plate portion 142. The side plate portion 142 extends circumferentially along the top plate portion 141 and folds towards the enclosure assembly 100. Meanwhile, the top of the enclosure assembly 100 is sequentially provided with a bending portion 101, a support portion 102, and a folded edge portion 103. In this embodiment, the support portion 102 is arranged parallel to the side plate portion 142, and the support portion 102 and the side plate portion 142 are connected together by screws. At this time, the end of the side plate portion 142 facing away from the top plate portion 141 is spaced apart from the bending portion 101 to form a first gap, and the top plate portion 141 is spaced apart from the folded edge portion 103 to form a second gap. This arrangement effectively reduces the contact area between the enclosure assembly 100 and the top cover 14, thus preventing paint wear or even peeling between the enclosure assembly 100 and the top plate portion 141 due to compressor operation or during machine handling.

[0048] It is important to further understand that the top plate 141 has multiple reinforcing areas, which are configured to enhance the structural strength of the top plate 141. These reinforcing areas can be arranged regularly or randomly to effectively increase their strength. Specifically, the thickness of the reinforcing areas of the top plate 141 is greater than that of the non-reinforced areas, or reinforcing ribs are provided in the reinforcing areas of the top plate 141 to increase its strength and prevent quality risks caused by insufficient clearance between the top plate 141 and internal components due to gravity sagging during use.

[0049] In this embodiment, a plurality of protrusions 144 are provided on the top plate portion 141, which are configured to strengthen the top plate portion 141. Each protrusion 144 is disposed in a strengthening region, and the top surface of the protrusion 144 is set as an arc surface, with the arc center correspondingly located close to the enclosure assembly 100. The arc surface design of the protrusions 144 can prevent the top plate portion 141 from sagging due to gravity, resulting in a small gap between it and the internal parts of the housing, thus preventing potential quality problems.

[0050] It should be noted that a number of reinforcing ribs (not shown in the figure) can also be provided on the top plate 141. The reinforcing ribs can further improve the structural strength of the top plate 141, thereby reducing the occurrence of the top plate 141 sagging due to gravity.

[0051] In addition, a chamfer 143 is provided at the connection between the top plate 141 and the side plate 142, which helps to improve the aesthetics of the top cover 14, and at the same time, it can prevent burrs from scratching the staff, and also helps to improve the structural strength of the top cover 14.

[0052] It needs to be further understood that the first gap is larger than the second gap, so that the second gap inside the housing is smaller than the first gap outside the housing. When the second gap disappears due to other conditions (such as gravity), that is, when the top plate 141 abuts against the folded edge 103, the first gap still exists because the support 102 is connected to the side plate 142. At this time, the top cover 14 collides with the enclosure assembly 100, causing scratches and paint peeling inside the housing, while no scratches or paint peeling will occur on the outside of the housing. This helps to reduce the corrosion of the outdoor unit 1 and ensure the service life of the outdoor unit 1.

[0053] Still Figure 1 As shown, the enclosure assembly 100 includes a front panel 12, a rear panel, a left side panel 131, and a right side panel 132. The top of each of the front panel 12, rear panel, left side panel 131, and right side panel 132 is provided with a bending portion 101, a support portion 102, and a folded edge portion 103. (Combined with...) Figure 2 and Figure 3 As shown, this embodiment will be described using the front panel 12 as an example. In this case, the top of the front panel 12 is provided with a bending portion 101, a support portion 102 and a folded edge portion 103 in sequence, wherein the folded edge portion 103 of the front panel 12 can be referred to as the first folded edge 121.

[0054] In this embodiment, a second gap exists between the first folded edge 121 and the top plate portion 141, and a first gap exists between the bent portion 101 and the side plate portion 142. Optionally, the value of the first gap ranges from 0.3mm to 1.5mm, and / or the value of the second gap ranges from 0.2mm to 0.8mm. In this embodiment, the first gap is 0.5mm and the second gap is 1mm. This arrangement helps to further ensure the size of the gap between the first and second gaps, thereby effectively preventing scratches and paint peeling on the exterior of the enclosure, further reducing the likelihood of rust on the outdoor unit 1, and ensuring the service life of the outdoor unit 1.

[0055] It should be noted that the value of the first gap can be set to 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, or 1.5mm. Meanwhile, the second gap can be set to 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, 0.55mm, 0.6mm, 0.65mm, 0.7mm, 0.75mm, or 0.8mm.

[0056] In addition, such as Figures 4-5 As shown, in this embodiment, the folded edge 103 on the left side plate 131 is called the second folded edge 1311, and the folded edge 103 on the right side plate 132 is called the third folded edge 1321. Along the length direction of the top cover 14, the extension length of the second folded edge 1311 is less than the extension length of the third folded edge 1321. On the one hand, this helps to reduce manufacturing costs. On the other hand, since the handle structure described below is set on the left side plate of the top cover 14, the top cover 14 is more likely to come into contact with the third folded edge 1321 during the handling of the outdoor unit 1. Therefore, setting the extension length of the third folded edge 1321 to be longer is more conducive to ensuring the support effect of the support part 102.

[0057] Furthermore, the support portion 102 extends along the first direction A, the bending portion 101 and the folded edge portion 103 extend along the second direction B respectively, and / or, the side plate portion 142 extends along the first direction A, and the top plate portion 141 extends along the second direction B, wherein the first direction A and the second direction B are perpendicular or at an angle.

[0058] Specifically, by arranging the support portion 102 and the bending portion 101 in different directions, it is helpful to adapt and connect them with the top cover 14, thereby helping to improve the installation effect of the outdoor unit 1.

[0059] It is necessary to understand that, such as Figure 1 and Figure 3As shown, the support portion 102 extends along a first direction A. In this embodiment, the first direction A is the vertical direction, and the support portion 102 is parallel to the front panel 12. Simultaneously, along the first direction (vertical direction), the bent portion 101 and the folded edge portion 103 are respectively provided at opposite ends of the support portion 102. Optionally, the bent portion 101 and the folded edge portion 103 extend along a second direction B, and the top plate portion 141 also extends along the second direction B. In this case, the bent portion 101 and the folded edge portion 103 are parallel, and simultaneously parallel to the top plate portion 141. In this embodiment, the bent portion 101 is perpendicular to the support portion 102. At this time, the bent portion 101 is parallel to the top plate portion 141. Simultaneously, along a direction perpendicular to the support portion 102, the bent portion 101 and the folded edge portion 103 are respectively provided on opposite sides of the support portion 102, thereby forming a U-shaped structure to facilitate the connection between the enclosure assembly 100 and the top cover 14. This arrangement helps increase the contact area between the folded edge portion 103 and the top plate portion 141 when the top plate portion 141 abuts against the folded edge portion 103, thereby improving the support effect of the support portion 102 on the top cover 14 and further preventing friction between the side plate portion 142 and the bent portion 101.

[0060] Furthermore, along the width direction of the top cover 14, a support portion 102 is provided on each side of the enclosure assembly 100. A first rib 124 is provided on the side of the support portion 102 facing the side plate portion 142, and the first rib 124 protrudes in the direction close to the side plate portion 142.

[0061] Specifically, by providing the first rib 124, the structural strength of the support portion 102 is improved, thereby enhancing its support effect on the folded edge portion 103. At the same time, by positioning the protrusion direction of the first rib 124 towards the side plate portion 142, the contact area between the support portion 102 and the side plate portion 142 is reduced, thereby reducing the contact area between the enclosure assembly 100 and the top cover 14.

[0062] It is necessary to understand that, such as Figure 1 , Figure 3 , Figure 4 and Figure 6As shown, along the width direction of the top cover 14, the two support portions 102 of the enclosure assembly 100 are the support portions 102 on the front panel 12 and the rear panel. Taking the support portion 102 on the front panel 12 as an example, the support portion 102 is provided with a first protruding rib 124. The protruding direction of the first protruding rib 124 is the direction close to the side panel portion 142 (towards the direction away from the interior of the housing). At the same time, the first protruding rib 124 is provided along the length direction of the top cover 14. Optionally, the first protruding rib 124 on the front panel 12 is provided as at least one segment. In this embodiment, along the length direction of the top cover 14, the first protruding rib 124 is three segments spaced apart. An installation structure and / or a reinforcing structure is provided between adjacent segments of the first protruding rib 124. The installation structure is a mounting hole for fixing the motor mounting bracket and the partition to the front panel 12 to ensure the assembly effect of the outdoor unit 1. Meanwhile, the reinforcing structure consists of reinforcing ribs, which are respectively set on opposite sides of the mounting hole along the length of the top cover 14. The protruding direction of the reinforcing ribs is set away from the side plate portion 142, which helps to improve the structural strength on both sides of the mounting hole, thereby ensuring the structural strength of the support portion 102.

[0063] It should be noted that the first protruding rib 124 on the front panel 12 can be set as a segment. In this case, the first protruding rib 124 and other structures (mounting holes and reinforcing ribs) are spaced apart in the vertical direction, which helps to reduce the influence of other structures on the first protruding rib 124 and ensure the connection between the front panel 12 and other components (motor bracket or side plate).

[0064] Furthermore, the first rib 124 on the rear panel has the same structure as the first rib 124 on the front panel 12, and its protrusion direction is opposite to that of the first rib 124 on the front panel 12. Meanwhile, the number and extension length of the first ribs 124 on the rear panel can be designed according to actual conditions, and no further restrictions are imposed here.

[0065] In addition, in this embodiment, the support portion 102 on the front panel 12 and the support portion 102 on the rear panel are spaced apart from the side panel portion 142. At this time, the support portion 102 on the left side panel 131 and the support portion 102 on the right side panel 132 are connected to the side panel portion 142 by screws to ensure the assembly effect of the outdoor unit 1 and to effectively reduce the contact area between the support portion 102 and the side panel portion 142, thereby helping to reduce the friction between the enclosure assembly 100 and the top cover 14.

[0066] Furthermore, the first rib 124 includes a reinforcing portion 1241 and an abutting portion 1242. The protruding length of the abutting portion 1242 is greater than the protruding length of the reinforcing portion 1241. The abutting portion 1242 is spaced apart from or abuts against the side plate portion 142.

[0067] Specifically, by configuring the first rib 124 into two parts, a reinforcing portion 1241 and an abutting portion 1242, and making the protruding length of the abutting portion 1242 greater than the protruding length of the reinforcing portion 1241, the contact between the first rib 124 and the side plate portion 142 can be further reduced, thereby helping to reduce friction between the front panel 12 and the side plate portion 142, as well as friction between the rear panel and the side plate portion 142. Simultaneously, by positioning the abutting portion 1242 at intervals or abutting against the side plate portion 142, the first rib 124 and the side plate portion 142 may either have point contact or form a space for movement, thereby further reducing the occurrence of scratches and paint peeling.

[0068] It is necessary to understand that, such as Figure 3 and Figure 4 As shown, the first rib 124 includes a reinforcing portion 1241 and an abutting portion 1242. The reinforcing portion 1241 is used to enhance the structural strength of the support portion 102. The abutting portion 1242 can directly abut against the side plate portion 142, or abut against the side plate portion 142 after the outdoor unit 1 vibrates or is subjected to external force. In this case, the abutting portion 1242 can both enhance the structural strength of the support portion 102 and provide support for the side plate portion 142, preventing the side plate portion 142 from rubbing against the entire support portion 102. Optionally, the first rib 124 includes at least one abutting portion 1242. In this embodiment, the first rib 124 is provided with two abutting portions 1242, which are respectively provided at opposite ends of the first rib 124 along the length direction of the top cover 14, which helps to further reduce the contact area between the front and rear panels and the side plate portion 142.

[0069] It should be noted that the first protruding rib 124 can all be set as the abutment part 1242, such as Figure 1 and Figure 6 Therefore, the rear panel includes a first part and a second part (not shown in the figure). The first part is connected to the left side panel 131 and is set as an integral part. The second part is connected to the right side panel 132 and is set as an integral part. Since the outdoor unit 1 requires a large ventilation channel, the first part and the second part have a shorter extension length along the length direction of the top cover 14. At this time, the first rib 124 can be set as the abutment part 1242 to ensure the structural strength of the support part 102 of the rear panel and reduce the contact area between the rear panel and the side panel part 142.

[0070] Furthermore, the first rib 124 has a first side facing the top plate portion 141 and a second side facing the bending portion 101. The first side has a first included angle α with the support portion 102, and the second side has a second included angle with the support portion 102. The first included angle is greater than the second included angle b.

[0071] Specifically, by setting the first included angle 'a' and the second included angle 'b', the manufacturing difficulty of the first protruding rib 124 on the front and rear panels is reduced. Moreover, the angled structure formed between the first protruding rib 124 and the support portion 102 helps to ensure the structural strength of the first protruding rib 124 and further improves the support effect of the support portion 102. At the same time, the first included angle 'a' is larger than the second included angle 'b', which facilitates the assembly of the top cover 14 and the enclosure assembly 100 and increases the difficulty of detaching the top cover 14 from the enclosure assembly 100, thus helping to improve the assembly effect of the outdoor unit 1.

[0072] It is necessary to understand that, such as Figure 3 As shown, along the vertical direction, the first side of the first rib 124 facing the top plate portion 141 is the upper side, and the second side of the first rib 124 facing the bent portion 101 is the lower side. The upper side forms a first angle α with the support portion 102, and the lower side forms a first angle b with the support portion 102. In this embodiment, both the first angle α and the second angle b are obtuse angles, and α > b. When the top cover 14 is installed on the surrounding panel assembly 100, the first angle α, being obtuse, guides the top cover 14, allowing it to be better assembled onto the surrounding panel assembly 100. Since the second angle b is also obtuse, it ensures the ease with which the top cover 14 can detach from the surrounding panel assembly 100. Furthermore, the second angle b is smaller than the first angle α and intersects the installation of the top cover 14, which helps to mitigate the detachment of the top cover 14.

[0073] Furthermore, along the length of the top cover 14, a side plate portion 142 is provided on each side of the top cover 14. A connecting recess 1421 is provided on the side plate portion 142, and a first connecting hole 14213 is provided on the bottom wall 14211 of the connecting recess 1421. At the same time, along the length of the top cover 14, a support portion 102 is provided on each side of the surrounding plate assembly 100. A second connecting hole 1302 is provided on the support portion 102, and the second connecting hole 1302 is used for fasteners to pass through and connect with the first connecting hole 14213.

[0074] Specifically, by providing the connecting recess 1421, the structural strength of two of the side plate portions 142 of the top cover 14 is improved, thereby enhancing the structural strength of the top cover 14. Simultaneously, by providing a first connecting hole 14213 on the bottom wall 14211 of the connecting recess 1421 to mate with the second connecting hole 1302 of the surrounding panel assembly 100, not only is the connection between the top cover 14 and the surrounding panel assembly 100 achieved, but the contact area between the support portion 102 and the side plate portion 142 is further reduced, thereby minimizing the occurrence of scratches.

[0075] It should be understood that, along the length of the top cover 14, the top cover 14 has two side plate portions 142, namely a left side plate portion and a right side plate portion. Each of the left and right side plate portions is provided with a connecting recess 1421. In this embodiment, as... Figure 1 and Figure 6 As shown, the connecting recess 1421 has a bottom wall 14211 and a side wall 14212. A first connecting hole 14213 is provided on the bottom wall 14211. A second connecting hole 1302 is provided on the right side plate 132. The number of second connecting holes 1302 is the same as the number of first connecting holes 14213, and they are arranged corresponding to the first connecting holes 14213. At this time, the screw connector can pass through the first connecting hole 14213 and be screwed into the second connecting hole 1302.

[0076] Furthermore, the number of connecting recesses 1421 is at least one. For example... Figure 6 As shown, taking the right side panel as an example, in this embodiment, two connecting recesses 1421 are provided on the right side panel. Along the width direction of the top cover 14, the two connecting recesses 1421 are respectively provided on opposite sides of the right side panel. At this time, the connecting recesses 1421 are connected to the top plate portion 141 of the top cover 14. By providing two connecting recesses 1421, the connection effect between the top cover 14 and the surrounding panel assembly 100 is improved.

[0077] At this time, a receiving groove is provided on the bottom wall 14211 of the recessed platform, and the receiving groove is arranged around the first connecting hole 14213. When the screw connector connects the side plate assembly 100 and the top cover 14, the screw head of the screw connector will be accommodated in the receiving groove. The setting of the receiving groove helps to further improve the structural strength of the side plate portion 142 and ensure the connection effect between the top cover 14 and the side plate assembly 100.

[0078] It is important to further understand that, along the length of the top cover 14, the two support portions 102 of the enclosure assembly 100 are each provided with a second rib 1301, and the second rib 1301 is spaced apart from the side plate portion 142. In this embodiment, both the right side plate 132 and the left side plate 131 are provided with the second rib 1301. Taking the right side plate 132 as an example, along the width of the top cover 14, the right side plate 132 is provided with two second connecting holes 1302, and the two second connecting holes 1302 are respectively located on opposite sides of the second rib 1301. By providing the second rib 1301, the structural strength of the left side plate 131 and the right side plate 132 is improved, and the impact of the second connecting holes 1302 on the support portion 102 is reduced. At the same time, the second rib 1301 is spaced apart from the side plate portion 142, which can reduce the communication effect between the external environment and the interior of the box, and also effectively reduce the contact area between the support portion 102 and the side plate portion 142.

[0079] It should be noted that the number of second ribs 1301 is at least one. When there is only one second connecting hole 1302, the second ribs 1301 and the second connecting hole 1302 can be arranged sequentially along the width direction of the top cover 14. Moreover, the number of second ribs 1301 can also be two or more, and they are correspondingly arranged on opposite sides of the second connecting hole 1302 to ensure the supporting effect of the support part 102. When there are multiple second connecting holes 1302, the second ribs 1301 and the second connecting holes 1302 can be staggered along the width direction of the top cover 14 to ensure the structural strength of the support part 102.

[0080] Still Figure 6 As shown, along the length of the top cover 14, two connecting recesses 1421 are provided on each of the two side plate portions 142 of the top cover 14. In this embodiment, two second connecting holes 1302 are provided on both the left side plate 131 and the right side plate 132. Since the connecting recesses 1421 are correspondingly provided with the second connecting holes 1302, there are also two connecting recesses 1421. Moreover, since the connecting recesses 1421 protrude towards the support portion 102, the recessed sidewalls 14212 of the two connecting recesses 1421 located on the same side plate portion 142 form a limiting space with the side plate portion 142. When the top cover 14 is installed on the top of the enclosure assembly 100, the second protruding rib 1301 is accommodated inside the limiting space, thereby restricting the movement of the second protruding rib 1301 along the width direction of the top cover 14, which helps to improve the connection effect between the top cover 14 and the enclosure assembly 100.

[0081] It should be noted that the left side panel has the same structure as the right side panel. However, the middle of the left side panel protrudes in a direction away from the right side panel to form a handle structure. Vertically, the bottom of the handle structure connects to the end of the left side panel away from the top cover 14, allowing the hand to reach between the left side panel and the left side panel 131. Optionally, the end of the handle structure away from the top cover 14 has a rolled edge to help prevent the top cover 14 from scratching the worker's hands.
