[0028] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] In view of the shortcomings of the prior art, this embodiment provides a portable air conditioner housing and a portable air conditioner, as detailed below: As attached Figure 1 Appendix Figure 2 and attached Figure 3 As shown, a portable air conditioner housing includes a front housing assembly 1, a cover plate 2, and a rear housing 3. The top of the front housing assembly 1 is provided with multiple first slots 11 and multiple screw fixing holes 12, providing a pre-positioning and final locking basis for top assembly. The cover plate 2 is located on the top of the front housing assembly 1, and the bottom of the cover plate 2 is provided with multiple first buckles 21 and multiple first fixing posts 22. The first slots 11 and the first buckles 21 correspond one-to-one and engage with each other, and the screw fixing holes 12 and the first fixing posts 22 correspond one-to-one and are locked by screws, realizing a step-by-step assembly structure of first engaging and positioning, and then screw locking. The rear housing 3 is assembled onto the front housing assembly 1 and the cover plate 2 by a plug-in engagement method, forming an external enclosure structure for the entire unit.

[0030] The front housing assembly 1 is the main load-bearing structure of the portable air conditioner, providing installation support for internal components such as the fan, evaporator, and electronic control system. A slot and screw holes are provided on the top for easy assembly of the cover plate 2. The cover plate 2 is the top decorative and protective component of the portable air conditioner, with a buckle and fixing post at the bottom for quick positioning and connection with the front housing assembly 1. The first slot 11 and the first buckle 21 form a pre-positioning engagement structure, which can stably lift and position the cover plate 2 before screwing, preventing slippage and displacement. The screw fixing hole 12 and the first fixing post 22 form the final locking structure, ensuring connection strength. The rear housing 3 is the back protection structure, assembled using a plug-in engagement method, eliminating the need for deep cavity screwing and simplifying the overall assembly process.

[0031] Specifically, during the overall assembly of the portable air conditioner housing, the operator first places the front housing assembly 1 stably on the assembly station. At this time, the front housing assembly 1 is in an independent and open state, with a completely open and unobstructed operating space. Then, the first buckle 21 at the bottom of the cover plate 2 is aligned with the first slot 11 at the top of the front housing assembly 1, and the cover plate 2 is pressed down evenly and gently so that all the buckles are simultaneously engaged in the slots, completing the initial positioning and support of the cover plate 2, ensuring that the cover plate 2 will not tilt, slip, or fall. After the cover plate 2 is stably positioned, the locking screws are passed through the screw fixing holes 12 in sequence and tightened with the first fixing post 22 to achieve a firm lock on the top. Finally, the rear housing 3 is smoothly pushed in from the rear or side of the front housing assembly 1 in a preset direction, so that the rear housing 3 forms a reliable plug-in engagement with the front housing assembly 1 and the cover plate 2. Without the need for any screw fastening operations in the closed deep cavity, the assembly process of the entire housing can be completed quickly, significantly reducing the assembly difficulty and improving the assembly efficiency.

[0032] Compared with existing technologies, traditional portable air conditioners first assemble the front and rear housings 3 to form a closed deep cavity, and then install the cover plate 2 from the top and tighten the screws. Due to the large assembly depth and narrow operating space, it is difficult to align the screws, poorly fasten them, warp the cover plate 2, and have uneven gaps, which seriously affects the assembly efficiency and appearance quality. This application uses a method of first pre-positioning with snap-fit, then fastening with screws, and finally inserting the rear housing 3. The cover plate 2 can be positioned and fastened before the front and rear housings 3 are assembled. The operating space is sufficient and the alignment is simple, which fundamentally solves the problems of difficult deep cavity assembly, poor fastening, and easy deformation of the cover plate 2.

[0033] Through the above technical solution, this application adopts a top assembly structure in which the first buckle 21 and the first slot 11 are first engaged and positioned, and then locked with screws. This avoids the defects of deep cavity closure and narrow operating space in traditional structures in terms of assembly process, making the assembly process of cover plate 2 more intuitive, smooth and reliable, effectively reducing the difficulty of manual alignment and assembly error rate, and greatly improving the production efficiency of the assembly line and the first pass rate of products. At the same time, it can ensure that the surface of cover plate 2 is flat, the gaps are uniform and consistent, and there is no warping or loosening after assembly, which significantly improves the appearance quality and structural connection strength of the whole machine, so that the portable air conditioner can maintain structural stability in long-term handling and operation vibration environment, and improve the overall reliability and service life of the product.

[0034] In this embodiment, as shown in the appendix Figure 1 As shown, the front housing assembly 1 includes a front panel 13, a panel 14, an air outlet panel 15, a control panel 16, and two handles 17. The front panel 13 has a first arc-shaped groove 131 at both ends of its top. The panel 14 is snapped onto the front end of the front panel 13 and is used for front appearance decoration and air intake protection. The air outlet panel 15 is rotatably disposed at the front end of the front panel 13 and located on top of the panel 14, and is used to adjust the air outlet direction. The control panel 16 is disposed at the front end of the front panel 13 and located on top of the air outlet panel 15, and is used to realize operation command input and status display. The two handles 17 are respectively disposed in the two first arc-shaped grooves 131 and connected to the front panel 13, and are used for moving and transporting the whole machine.

[0035] Among them, the front panel 13 is the main frame of the front shell assembly 1, providing structural strength and the foundation for the installation of various components. The first arc-shaped groove 131 at the top is used to avoid and accommodate the handle 17, ensuring a flat appearance. The front panel 13 is U-shaped in general. The panel 14 is a front decoration and protection component, which adopts a snap-fit ​​structure for easy disassembly and maintenance. The air outlet 15 is an adjustable air guide component to achieve multi-angle air delivery. The control panel 16 is a user interaction interface with a reasonable layout for easy operation. The handle 17 is a moving force-bearing component, which is embedded in the arc-shaped groove so as not to protrude and affect the appearance, while meeting the need for lifting.

[0036] Specifically, during the assembly of the front housing assembly 1, the front panel 13 is first fixed on the assembly fixture, and the front functional components are installed sequentially. The panel 14 is first pushed from top to bottom into the installation area at the front end of the front panel 13 along the positioning direction, so that it is snapped and fixed with the front panel 13, thereby achieving the sealing and protection of the front appearance. Next, the air outlet panel 15 is assembled to the corresponding position above the panel 14 through the pivot structure, ensuring smooth swing without jamming or abnormal noise. Then, the control panel 16 is fixed in the preset installation area above the air outlet panel 15, completing the wiring connection and position fixation. Finally, the two handles 17 are respectively embedded into the first arc-shaped grooves 131 at both ends of the top of the front panel 13, and the handles 17 are reliably connected to the front panel 13 through fasteners, so that the handles 17 are completely hidden inside the arc-shaped grooves and do not protrude from the housing surface, forming a front housing assembly 1 with a uniform appearance and complete structure, which facilitates subsequent final assembly.

[0037] Through the above technical solution, this application sets the front shell assembly 1 as a modular combination structure, so that the front panel 13, panel 14, air outlet panel 15, control panel 16, and handle 17 can all be independently assembled and replaced, which greatly improves production assembly efficiency and later maintenance convenience, and reduces maintenance costs; at the same time, the embedded arc groove is used to accommodate the handle 17, which not only ensures the smooth and simple appearance of the whole machine, reduces the packaging volume and transportation space, but also meets the needs of mobile carrying, achieving a unity of beautiful appearance, structural strength and ease of use, and improving the overall quality and market competitiveness of the portable air conditioner.

[0038] In this embodiment, as shown in the appendix Figure 5 and attached Figure 7 As shown, the front end of the front panel 13 is provided with a mounting groove 132, and the inner wall of the mounting groove 132 is provided with a plurality of second slots 133 and a guide plate 134; the end of the panel 14 near the front panel 13 is provided with a plurality of second buckles 141 and a guide groove 142, the second slots 133 and the second buckles 141 correspond one to one and engage with each other, and the guide plate 134 and the guide groove 142 cooperate with each other.

[0039] The mounting groove 132 provides space for the panel 14 to be embedded, ensuring that the panel 14 is flush with the front panel 13 and improving the overall appearance. The second slot 133 and the second buckle 141 are quick-connect structures for the panel 14, which can be firmly fixed without screws. The guide plate 134 and the guide groove 142 are insertion guide structures, which can ensure that the panel 14 is inserted in a precise direction, avoiding skew, jamming and uneven gaps, while improving the success rate of the connection.

[0040] Specifically, when assembling panel 14, the operator first precisely aligns the guide groove 142 on the back of panel 14 with the guide plate 134 in the mounting groove 132 of front panel 13, and then smoothly and slowly pushes panel 14 into the mounting groove 132 along the guide direction. During the pushing process, the guide plate 134 and the guide groove 142 continuously provide guiding constraints to ensure that panel 14 does not shift left or right or tilt. When panel 14 is pushed into place, the second buckle 141 automatically pops into the second buckle 133 under the action of elasticity, giving a clear indication of being in place. Panel 14 and the surface of front panel 13 are completely flush and fit together, without steps, warping, or looseness. The entire assembly can be completed without the use of any screws. Disassembly can also be completed without damage by directly prying the buckle.

[0041] Compared with existing technologies, traditional panel 14 assembly often uses screw fastening or direct snap-in without guidance, which is prone to problems such as misalignment, inconsistent gap size, incomplete snap-in, and easy breakage during disassembly and assembly. This application combines guided cooperation with multi-point snap-in to make panel 14 assembly positioning precise, snap-in firm, and easy to disassemble and assemble, with higher appearance consistency.

[0042] Through the above technical solution, this application adopts a panel 14 assembly structure that combines guiding and locking, realizing the rapid assembly of panel 14 with screwless, high precision and high firmness. It effectively avoids problems such as uneven gaps, panel 14 tilting and loose connection caused by manual alignment deviation, and improves the appearance quality and assembly consistency of the front of the machine. At the same time, the disassembly and assembly process is simple and quick, and it is not easy to damage the parts, which greatly improves production efficiency and after-sales maintenance convenience, and reduces the cost of use.

[0043] Furthermore, a first receiving groove is provided on the inner side of the front panel 13, and a screw mounting hole is provided on the first receiving groove. A fourth fixing post is provided on the side of the panel 14 near the front panel 13. The fourth fixing post is located in the first receiving groove and cooperates with the screw mounting hole. The screw mounting hole and the fourth fixing post can be fixed by screws, which further increases the connection stability between the panel 14 and the front panel 13.

[0044] In this embodiment, as shown in the appendix Figure 3 and attached Figure 6 As shown, multiple first slots 11 and multiple screw fixing holes 12 are located on the top of the front plate 13. Multiple third buckles 135 are provided on the top of the front plate 13, and multiple third slots 23 are provided on the top of the cover plate 2. The third buckles 135 and the third slots 23 correspond to each other and cooperate with each other.

[0045] The first slot 11 and screw fixing hole 12 at the top of the front plate 13 are used for positioning and locking the bottom of the cover plate 2; the third buckle 135 is set at the top of the front plate 13 to provide top auxiliary positioning for the cover plate 2; the third slot 23 is opened at the corresponding position of the cover plate 2, forming a top constraint with the third buckle 135, further limiting the front-back and left-right displacement and warping deformation of the cover plate 2, and improving the positioning accuracy and connection stability of the cover plate 2; the multiple first slots 11 are arranged in a U-shape, and the screw fixing hole 12 and the third buckle 135 are set at the front end of the front plate 13.

[0046] Specifically, during the assembly of cover plate 2, when the first snap 21 at the bottom of cover plate 2 engages with the first slot 11 of front plate 13, the third snap 135 at the top of front plate 13 will simultaneously align and engage with the third slot 23 at the top of cover plate 2, forming a double positioning constraint at the bottom and top. The double engagement structure will simultaneously restrict the displacement and deformation of cover plate 2 from both the top and bottom directions, so that cover plate 2 is in a completely stable, non-shaking, and non-warping state before the screws are fastened, providing a more accurate positional basis for subsequent screw fastening and effectively preventing cover plate 2 from shifting under force when the screws are fastened.

[0047] Compared with existing technologies, traditional cover plates 2 rely on bottom or one side for positioning, which is prone to problems such as top warping, front and back movement, and uneven gaps, affecting appearance and sealing performance. This application uses double-locking positioning at the bottom and top to make the cover plate 2 more accurately positioned and more firmly fixed, completely improving the warping and misalignment problems.

[0048] Through the above technical solution, this application adds a top third buckle 135 and a third slot 23 cooperation structure between the cover plate 2 and the front plate 13, forming an all-round dual positioning system with the bottom first buckle 21 and the first slot 11. This effectively restricts the warping deformation, left and right offset and front and back movement of the cover plate 2 during assembly and use, significantly improving the assembly accuracy and appearance flatness of the cover plate 2; at the same time, it enhances the overall structural stability of the shell, reduces the risk of loosening and abnormal noise caused by operating vibration, and improves the service life and user experience of the portable air conditioner.

[0049] In this embodiment, as shown in the appendix Figure 4 Appendix Figure 5 and attached Figure 8 As shown, a third fixing post 171 is provided at one end of the handle 17 near the front plate 13. A through hole 18 corresponding to the third fixing post 171 is provided on the front plate 13. The through hole 18 is connected to the third fixing post 171 by screws. One of the screw fixing holes 12 is provided at one end of the handle 17 away from the front plate 13 and is connected to the corresponding first fixing post 22 by screws.

[0050] The third fixing post 171 and the through hole 18 are the inner fixing structures of the handle 17, ensuring the connection strength between the handle 17 and the front plate 13; the screw fixing hole 12 at the outer end of the handle 17 is connected to the first fixing post 22 of the cover plate 2, so that the handle 17 is locked to the front plate 13 and the cover plate 2 at the same time, realizing three-point force and overall reinforcement, significantly improving the pull-out strength and service life of the handle 17.

[0051] Specifically, when assembling the handle 17, first insert the third fixing post 171 on the inner side of the handle 17 into the corresponding through hole 18 of the front plate 13, and use screws to lock and fix it from the inside, so that the inner side of the handle 17 and the front plate 13 form a rigid connection; then install the cover plate 2, and precisely align the screw fixing hole 12 at the outer end of the handle 17 with the first fixing post 22 at the bottom of the cover plate 2, and use screws to lock the handle 17 and the cover plate 2; through this method of locking on both sides, the handle 17 is fixed to the two main structures of the front housing assembly 1 and the cover plate 2 at the same time, forming a stable structure with multi-point support and overall force bearing, so that the force is more even when lifting and moving, and there will be no breakage or loosening caused by local stress concentration.

[0052] Through the above technical solution, this application adopts a structural design in which the handle 17 is simultaneously locked and fixed to the front plate 13 and the cover plate 2 in both directions. This makes the handle 17 no longer rely solely on the single-sided shell for support, but rather the lifting force is shared by the front shell assembly 1 and the cover plate 2. This significantly improves the pull-out strength, fatigue resistance and service life of the handle 17. It effectively avoids problems such as loosening, breakage and abnormal noise of the handle 17 caused by frequent movement, and improves the safety and reliability of the portable air conditioner. It is especially suitable for long-term and high-frequency moving use scenarios.

[0053] Furthermore, a snap-fit ​​block is provided on the inner side of the handle 17, and a snap hook is provided on the end of the cover plate 2 near the handle 17. The snap hook engages with the snap-fit ​​block, further increasing the connection stability between the handle 17 and the cover plate 2.

[0054] In this embodiment, as shown in the appendix Figure 2 Appendix Figure 6 and attached Figure 9 As shown, the cover plate 2 is provided with multiple fourth slots 24 and multiple first guide blocks 25 at one end near the rear housing 3, the front plate 13 is provided with multiple fifth slots 136 and multiple second guide blocks 137 at one end near the rear housing 3, and the rear housing 3 is provided with multiple fourth buckles 31 and multiple fifth buckles 32 at one end near the front plate 13; the fourth buckles 31 correspond one-to-one with the fourth slots 24 and engage with each other, and the fifth buckles 32 correspond one-to-one with the fifth slots 136 and engage with each other.

[0055] The fourth slot 24 and the first guide block 25 are located on the rear side of the cover plate 2 and face the rear housing 3, and are used to position and engage with the upper part of the rear housing 3; the fifth slot 136 and the second guide block 137 are located on the rear side of the front plate 13 and face the rear housing 3, and are used to position and engage with the lower part of the rear housing 3; the fourth buckle 31 and the fifth buckle 32 are set on the rear housing 3 to form a multi-point engagement structure; the first and second guide blocks are used for insertion guidance to ensure smooth assembly and accurate alignment of the rear housing 3.

[0056] Specifically, when assembling the rear housing 3, the operator smoothly pushes the rear housing 3 horizontally toward the front housing assembly 1 and the cover plate 2, so that the fourth buckle 31 on the rear housing 3 aligns with the fourth slot 24 on the rear side of the cover plate 2, and the fifth buckle 32 aligns with the fifth slot 136 on the rear side of the front plate 13. During the pushing process, the first guide block 25 and the second guide block 137 simultaneously provide guiding and limiting functions to ensure that the rear housing 3 will not be tilted, deviated, or jammed. When the rear housing 3 is pushed into place, the fourth buckle 31 and the fifth buckle 32 simultaneously spring into the corresponding slots, forming a multi-point synchronous clamping, and the rear housing 3 can be quickly assembled without any tools.

[0057] Through the above technical solution, this application adopts a plug-in rear housing 3 assembly structure with multiple sets of upper and lower buckles and slots in conjunction with double guide blocks, which realizes screwless, fully automatic, highly stable and rapid assembly of the rear housing 3, greatly reducing assembly difficulty, shortening assembly time and improving production line efficiency; at the same time, it ensures that the rear housing 3 is accurately positioned, has uniform gaps and is firmly connected after assembly, effectively avoiding problems such as vibration and abnormal noise, loosening of the housing, and falling off, and improving the overall structural stability and reliability of the machine.

[0058] In this embodiment, as shown in the appendix Figure 2 and attached Figure 9 As shown, a protrusion 138 is provided at the bottom of the front plate 13 near the rear housing 3, and a first slot 139 is provided on the protrusion 138. A second slot 33 is provided at the bottom of the rear housing 3 near the front plate 13. The first slot 139 and the second slot 33 correspond to each other and are connected by bolts.

[0059] Among them, the protrusion 138 and the first slot 139 are the bottom reinforcement connection structure of the front plate 13; the second slot 33 is correspondingly set at the bottom of the rear housing 3; the bottom of the front and rear housings 3 are locked by bolts to form a bottom reinforcement fixing point, which, together with the upper multiple sets of buckles, forms a fixed system that combines the upper and lower parts, further improving the structural strength and stability of the whole machine.

[0060] Specifically, after the rear housing 3 is inserted and engaged by the upper buckle, the protrusion 138 at the bottom of the front plate 13 will precisely fit with the corresponding position at the bottom of the rear housing 3, and the first slot 139 and the second slot 33 will automatically align. At this time, the operator can pass the bolt through the two sets of slots from the outside of the housing and lock it, so that the bottom of the front and rear housings 3 forms a rigid and fastened connection. The bottom locking point cooperates with the multiple upper buckles to form a composite fixing mode of upper locking and lower locking, making the connection between the front and rear housings 3 more stable and preventing separation, cracking, or widening of gaps due to external forces or vibrations.

[0061] Through the above technical solution, this application adds protrusions 138, slots and bolt locking structures to the bottom of the front panel 13 and the rear housing 3, forming an all-round composite fixing system with the upper multi-point buckle, which greatly improves the overall structural strength, deformation resistance and impact resistance; effectively avoids problems such as cracking at the bottom of the front and rear housings 3, widening of gaps, loosening and abnormal noise during movement and transportation, improves the overall structural stability, sealing and durability, and extends the service life of the portable air conditioner.

[0062] In this embodiment, as shown in the appendix Figure 9 As shown, a second arc-shaped groove 34 is provided at one end of the rear housing 3 near the front plate 13. The second arc-shaped groove 34 cooperates with the first arc-shaped groove 131 to accommodate the handle 17. A positioning hole 172 is provided at one end of the handle 17 near the rear housing 3. A positioning protrusion 35 is provided at one end of the rear housing 3 near the handle 17. The positioning protrusion 35 is engaged with the positioning hole 172.

[0063] The second arc-shaped groove 34 and the first arc-shaped groove 131 together form a complete space for the handle 17, so that the handle 17 is completely embedded, the appearance is simpler and smoother, and the packaging volume is not increased; the positioning hole 172 and the positioning protrusion 35 are auxiliary positioning structures at the rear end of the handle 17, which further restricts the shaking and displacement of the handle 17 and improves the installation stability of the handle 17.

[0064] Specifically, when the rear housing 3 is assembled in place, the second arc-shaped groove 34 on the rear housing 3 automatically aligns and surrounds the first arc-shaped groove 131 on the front plate 13, completely enclosing the handle 17 inside the housing, so that the handle 17 does not protrude from the overall outline of the machine; at the same time, the positioning protrusion 35 on the rear housing 3 will precisely engage with the positioning hole 172 at the end of the handle 17, forming a positioning constraint at the rear end of the handle 17, so that the handle 17 cannot wobble in the front-back and left-right directions, ensuring that the handle 17 is assembled stably and that there will be no play, shaking or abnormal noise during the lifting process.

[0065] Through the above technical solution, this application adopts a dual structure of front and rear shells surrounded by three arc-shaped grooves and positioning protrusions 35 and positioning holes 172, which enables the handle 17 to be fully embedded, making the appearance more neat, uniform, smooth and beautiful, while reducing the packaging volume and transportation costs; the rear positioning structure of the handle 17 can effectively eliminate shaking gaps and abnormal noises, improve the installation stability and user feel of the handle 17, and comprehensively improve the overall quality, user experience and product competitiveness of the portable air conditioner.

[0066] In this embodiment, as shown in the appendix Figure 4 As shown, a plurality of abutment plates 36 are provided on the inner wall of the rear housing 3 near the front plate 13, and the abutment plates 36 abut against the side wall of the first guide block 25.

[0067] Among them, the abutment plate 36 is an internal reinforcing rib plate of the rear shell 3, which is used to tightly abut against the first guide block 25 on the rear side of the cover plate 2; through surface contact support, it eliminates assembly gaps, limits shell deformation, improves structural rigidity, and at the same time ensures the assembly in place indication function.

[0068] Specifically, when the rear housing 3 is pushed in along the guide direction and the snap-fit ​​assembly is completed, the multiple abutment plates 36 on the inner wall of the rear housing 3 will simultaneously form a tight surface contact with the side wall of the first guide block 25 on the rear side of the cover plate 2, filling the assembly gap and providing uniform internal support. The supporting effect of the abutment plates 36 can prevent the rear housing 3 from denting inward when subjected to external pressure, while ensuring that the rear housing 3 is assembled in place without any play or looseness, thus significantly improving the rigidity and stability of the entire back housing.

[0069] Through the above technical solution, this application provides an abutment plate 36 on the inner wall of the rear housing 3 to form a tight support fit with the first guide block 25, effectively eliminating the assembly gap between the rear housing 3 and the cover plate 2, avoiding problems such as loosening, shaking, and abnormal noise; at the same time, it significantly enhances the structural rigidity and pressure resistance of the rear housing 3, preventing situations such as pressing indentation, deformation, and cracking during use, further improving the overall structural stability, sealing and durability, so that the portable air conditioner can still maintain stable and reliable operation in complex usage environments.

[0070] Furthermore, a first recessed groove is provided on the outer side of the rear housing 3. The shape of the first groove matches the outer contour of the rear end of the front plate 13. During the assembly of the front plate 13 and the rear housing 3, the rear edge of the front plate 13 can be precisely embedded into the first groove and tightly abut against it. The concave-convex fit structure forms a stable and reliable lateral snap-fit ​​structure, effectively limiting the relative displacement of the front plate 13 and the rear housing 3 in the left-right and up-down directions, avoiding problems such as housing misalignment, widening gaps, or loosening and abnormal noise after assembly. At the same time, a gap is reserved between the first guide plate 134 on the rear side of the cover plate 2 and the inner sidewall of the front plate 13 after assembly. A certain gap in the fit can easily lead to misalignment, wobbling, or poor sealing at the joint of the housing. However, after the rear housing 3 is fully assembled, the multiple abutment plates 36 set on the inner side of the rear housing 3 can precisely fill the gap between the first guide plate 134 and the inner wall of the front plate 13. The abutment plates 36 form a tight fit and support with the inner wall of the front plate 13 and the side wall of the first guide plate 134, respectively, eliminating misalignment and gap from the inside. This further improves the tightness and integrity of the joint between the front plate 13, the cover plate 2, and the rear housing 3, making the structure of the entire mobile air conditioner housing more stable and rigid, and maintaining stability and reliability during long-term operation, vibration, and transportation.

[0071] This application also provides a portable air conditioner, including the aforementioned portable air conditioner housing.
