[0038] Air conditioner compressors generate considerable noise during operation, and sheet metal soundproofing covers are often installed to reduce this noise. These covers are typically heavy, and require multiple screws to secure them to the plastic air conditioner chassis. However, tightening these multiple screws takes a long time, making installation of these covers inefficient.

[0039] The utility model provides an air conditioner.

[0040] See also Figures 1 to 5In one embodiment of the present invention, the air conditioner includes a chassis 300, a compressor (not shown) and a compressor cover 100, wherein the chassis 300 can be the chassis 300 of the indoor unit of the air conditioner, or the chassis 300 of the outdoor unit of the air conditioner. The compressor is installed on the chassis 300, that is, the compressor can be installed in the indoor unit of the air conditioner, or it can be installed in the outdoor unit of the air conditioner. The compressor cover 100 covers the outside of the compressor to accommodate the compressor in the accommodating cavity 150, so as to reduce the outward propagation of the compressor system noise and reflect the noise as much as possible in the compressor cover 100. In one embodiment, the entire compressor cover 100 wraps the compressor and piping inside. Except for the connecting port for the piping and wires to pass through, the rest are all solid structures. The high sealing feature can reduce the sound leakage area, avoid sound energy leakage and diffraction, and thus greatly improve the noise reduction effect.

[0041] In one embodiment, to enhance noise reduction, sound insulation cotton (not shown) is provided on the inner side of the compressor cover 100. The sound insulation cotton can be secured to the compressor cover 100 using various methods, such as glue, double-sided tape, 3M adhesive, rivet nuts, tightening straps, and screws. The sound insulation cotton can be made from one or more of PP / PET two-component sound insulation cotton, glass fiber cotton, non-woven fiber cotton, needle-punched felt cotton, polyester fiber cotton, rock wool, and slag wool. The present invention utilizes high-performance sound insulation cotton material. The porous structure of the sound insulation cotton can convert sound energy into heat energy through viscosity and friction, thereby absorbing and dissipating it.

[0042] In one embodiment, to further enhance the noise reduction effect, at least one compressor cover 100 and at least one layer of sound insulation cotton are disposed outside the compressor, with the sound insulation cotton disposed closest to the compressor. It is understood that the compressor generates vibration and noise during operation. The primary function of the sound insulation cotton is to absorb noise, while the primary function of the compressor cover 100 is to seal the noise. Placing the sound insulation cotton directly near the compressor allows for more direct and rapid noise absorption. In the present invention, the sound insulation cotton is made of a soft, porous, and highly sound-absorbing material. When sound waves enter the pores, they cause the fibers to vibrate, converting the sound energy into heat energy through viscosity and friction, thereby being absorbed and dissipated. The provision of the compressor cover 100 can reduce the outward propagation of compressor system noise and reflect the noise as much as possible within the compressor cover 100. The compressor cover 100 is constructed of a dense, heavy material to increase mid- and low-frequency sound insulation and noise reduction, thereby blocking and sealing the noise within the internal space so that it is repeatedly absorbed by the sound insulation cotton, isolating it from the surrounding air.

[0043] In one embodiment, the sound insulation cotton has two layers, and the compressor cover 100 has two layers. One sound insulation cotton is used to wrap the compressor, and one compressor cover 100, another sound insulation cotton, and another compressor cover 100 are sequentially arranged on its outer side. In another embodiment, the sound insulation cotton has two layers, and the compressor cover 100 has one layer. One sound insulation cotton is used to wrap the compressor, and the compressor cover 100 and another sound insulation cotton are sequentially arranged on its outer side; or another sound insulation cotton and the compressor cover 100 are sequentially arranged on its outer side. In yet another embodiment, the sound insulation cotton has one layer, and the compressor cover 100 has two layers. The sound insulation cotton is used to wrap the compressor, and one compressor cover 100 and another compressor cover 100 are sequentially arranged on its outer side.

[0044] In one embodiment, the compressor cover 100 is made of metal, including but not limited to one or more of damping steel plate, vibration-damping composite steel plate, hot-dip galvanized steel plate, aluminum plate, and stainless steel plate. The metal compressor cover 100 can be formed using sheet metal technology. It is understandable that the chassis 300 of the air conditioner is generally made of plastic. The metal compressor cover 100 is generally heavy. When the heavy metal parts are connected to the plastic parts, many screws are generally required to fix them, which affects the assembly efficiency. The compressor cover 100 and the chassis 300 in the present invention are fixed by a snap connection, thereby improving the assembly efficiency of the air conditioner. Of course, the compressor cover 100 can also be made of non-metallic materials, including but not limited to one or more of ABS plastic, PP plastic, HIPS plastic, hard rubber, etc. The non-metal compressor cover 100 and the chassis 300 can also be connected by a snap connection.

[0045] The technical solution of the present invention is to provide a chassis 300, a compressor, and a compressor cover 100 in the air conditioner. The compressor is mounted on the chassis 300, and the compressor cover 100 is disposed outside the compressor. The compressor cover 100 is snap-fitted to the chassis 300. Thus, compared to the prior art method of fastening the compressor cover 100 and chassis 300 with multiple screws, the compressor cover 100 and chassis 300 in the present invention are connected by snapping, thus eliminating the tedious operation of fastening multiple screws, saving time, and improving the assembly efficiency of the air conditioner.

[0046] In the embodiments of the present invention, please refer to Figure 2 and Figure 3One of the compressor cover 100 and the chassis 300 is provided with a pin 180, and the other is provided with a slot 310. The pin 180 engages with the slot 310. In one embodiment, the compressor cover 100 is made of metal and the chassis 300 is made of plastic. Considering the structural strength and ease of processing of metal and plastic materials, the pin 180 may be provided on the compressor cover 100, while the slot 310 may be provided on the chassis 300. However, the present design is not limited to this. In other embodiments, the compressor cover 100 may be provided with both the pin 180 and the slot 310, while the chassis 300 may be provided with a corresponding slot 310 and pin 180. This is sufficient as long as the pin 180 and slot 310 engage in a one-to-one correspondence. Of course, in other embodiments, one of the compressor cover 100 and the chassis 300 may be provided with a latching pin, while the other may be provided with a latching hole. The latching pin engages with the latching hole to connect the compressor cover 100 and the chassis 300.

[0047] As will be appreciated, when pins 180 are mounted on the compressor cover 100, the compressor cover 100 comprises the cover body and pins 180, with pins 180 and the cover body being coplanar. When pins 180 are mounted on the chassis 300, they are located at the upper ends of the sidewalls of the chassis 300 and coplanar with the sidewalls. This facilitates precise mold processing and ensures accurate assembly of the compressor cover 100 and chassis 300.

[0048] In the embodiments of the present invention, please refer to Figure 4 Slot 310 is provided with a guide structure, comprising a guide rib 320 mounted on one sidewall of slot 310. The guide rib 320 extends along the depth of slot 310, and a guide slope 321 is provided on one end of the guide rib 320, near the notch of slot 310. The guide slope 321 extends obliquely along the depth of slot 310 toward the other sidewall of slot 310. This guide structure provides precise guidance for the connection between pin 180 and slot 310, improving the efficiency of the engagement between pin 180 and slot 310.

[0049] In the embodiment shown in the drawings of the present invention, the guide structure is configured as a guide rib 320 installed within the slot 310. Along the depth of the slot 310, the guide rib 320 is provided with a connected guide slope 321 and a locking surface 322. The guide slope 321 is inclined from the slot opening to the bottom of the slot 310, gradually approaching the other sidewall of the slot 310. When the pin 180 is to be inserted into the slot 310, the pin 180 is aligned with the slot 310 and moved downward. The pin 180 first contacts the guide slope 321 and then slides along the guide slope 321, causing one side of the pin 180 to abut against the locking surface 322 of the guide rib 320. The locking surface 322 extends parallel to the insertion direction of the pin 180, facilitating accurate insertion of the pin 180 into the slot 310. In this manner, the pin 180 is inserted into the slot 310, achieving the locking connection between the compressor cover 100 and the chassis 300.

[0050] In one embodiment, multiple guide ribs 320 are provided within the slot 310. The guide ribs 320 are spaced apart along a side wall of the slot 310 to provide more precise guidance and positioning for the insertion of the pin 180. However, the present design is not limited thereto. In other embodiments, the slot 310 may also be configured as a V-shaped groove to achieve a guiding function.

[0051] In an embodiment of the present invention, multiple pins 180 are provided, spaced apart along the circumference of the compressor cover 100, with slots 310 corresponding to the pins 180. This arrangement of multiple pins 180 and slots 310 improves the connection stability between the compressor cover 100 and the chassis 300. In one embodiment, a pin 180 is provided on each side of the compressor cover 100, and slots 310 are provided at corresponding positions on the chassis 300. This improves the balance of force applied to the connection between the compressor cover 100 and the chassis 300, thereby enhancing the overall structural strength of the air conditioner.

[0052] In the embodiments of the present invention, please refer to Figure 1 The compressor cover 100 includes a first side panel 110, a second side panel 120 detachably connected to the first side panel 110, and a top cover 130 detachably connected to the first side panel 110 and the second side panel 120. The first side panel 110, the second side panel 120, and the top cover 130 enclose a receiving cavity 150. In this way, the difficulty of producing the compressor cover 100 is reduced by dividing the compressor cover 100 into several splicing parts. In another embodiment, the compressor cover 100 may further include an upper end cover and a side panel, wherein the side panel is cylindrical and has an opening at both ends. The upper end cover is detachably connected to an open end of the side panel. In this way, the split setting of the compressor cover 100 can also be realized, thereby improving the efficiency of disassembly and assembly of the compressor cover 100. However, the present design is not limited to this. In other embodiments, the compressor cover 100 is an integrally molded component.

[0053] In one embodiment, the first side panel 110 and the second side panel 120 are connected via a snap-fit structure. This fastening allows the first and second side panels 110, 120 to be quickly joined together, making installation and removal of the compressor cover 100 easier. This also facilitates assembly of the compressor cover 100's internal structure, fully utilizing the space available. Efficient assembly of the compressor cover 100 can also meet the high production speeds of air conditioner production lines. However, this design is not limited to this. In other embodiments, the first and second side panels 110, 120 are screwed together to enhance the stability of their connection.

[0054] In one embodiment, see Figure 2 One of the first side panel 110 and the second side panel 120 is provided with a hook 121, and the other is provided with a slot 111. The hook 121 engages with the slot 111 to connect the first side panel 110 and the second side panel 120. In one embodiment, multiple slots 111 are spaced apart on the first side panel 110, and multiple hooks 121 are spaced apart on the second side panel 120. The number and position of the slots 111 and the hooks 121 correspond. This improves the stability and reliability of the connection between the first side panel 110 and the second side panel 120. Of course, it is also possible to provide both the slots 111 and the hooks 121 on the first side panel 110, and correspondingly provide the hooks 121 and the slots 111 on the second side panel 120. As long as the hooks 121 and the slots 111 engage in a one-to-one correspondence, it will suffice.

[0055] However, the present design is not limited thereto. In other embodiments, one of the first side panel 110 and the second side panel 120 may be provided with a snap-fit pin, and the other one may be provided with a snap-fit hole. In this way, the snap-fitting of the first side panel 110 and the second side panel 120 can also be achieved.

[0056] In one embodiment, the card slot 111 includes a connected insertion slot (not shown) and a connecting slot (not shown), the diameter of the connecting slot is smaller than the insertion slot, and the hook 121 is inserted into the connecting slot. Specifically, the card slot 111 is a special-shaped slot, which includes a connected insertion slot and a connecting slot. When the hook 121 is connected to the card slot 111, the hook 121 first extends into the insertion slot portion of the card slot 111, and then slides into the connecting slot portion, thereby inserting the hook 121 into the connecting slot. The setting of the insertion slot having a diameter larger than the connecting slot allows the hook 121 to easily enter the insertion slot, eliminating the need to accurately align the hook 121 and the card slot 111 in advance, thereby improving the simplicity of connecting the hook 121 and the card slot 111.

[0057] In one embodiment, the diameter of the engaging slot gradually decreases in the direction away from the insertion slot, so that the engagement between the hook 121 and the engaging slot is more secure, preventing the hook 121 from falling out of the engaging slot.

[0058] In one embodiment, see Figure 2 The hook 121 is provided on the second side panel 120. The hook 121 includes a contact portion 122 and an anti-slip portion 123. The hook 121 is inserted into the snap-fit groove so that the contact portion 122 contacts the bottom wall of the snap-fit groove. The anti-slip portion 123 is located on the side of the first side panel 110 away from the second side panel 120.

[0059] As will be appreciated, the abutment portion 122 and the anti-slip portion 123 are arranged at an angle. In one embodiment, the abutment portion 122 and the anti-slip portion 123 are arranged in an "L" shape. When the hook 121 is inserted into the slot 111, the abutment portion 122 contacts the bottom wall of the slot, and the anti-slip portion 123 contacts the side of the first side panel 110 facing away from the second side panel 120. The abutment portion 122 ensures that the hook 121 and the slot 111 are securely connected, while the anti-slip portion 123 prevents the hook 121 from being dislodged from the slot 111, thereby preventing the connection between the first and second side panels 110, 120 from being lost.

[0060] In one embodiment, see Figure 2 The hook 121 is provided with a rib 124, which is used to abut against the sidewalls of the engaging slot. Specifically, the rib 124 can be convex or concave on the hook 121. When the hook 121 is engaged with the engaging slot 111, the rib 124 abuts against the sidewalls of the engaging slot. The provision of the rib 124 reduces the precision of the fit between the hook 121 and the engaging slot 111, and reduces the difficulty of manufacturing the hook 121 and the engaging slot 111.

[0061] In one embodiment, see Figure 5 The first side panel 110 and the second side panel 120 both include a panel body 171. The panel body 171 is connected to an extension section 172 at one end close to the top cover 130. The extension section 172 is concave relative to the panel body 171, and a step portion 173 is formed between the two. The extension section 172 extends into the top cover 130, and the cover edge of the top cover 130 abuts against the step portion 173.

[0062] As will be appreciated, when the first and second side panels 110, 120 are combined, the circumference of the extended section 172 along the circumference of the compressor cover 100 is smaller than the circumference of the panel body 171. Thus, when the top cover 130 is connected to the first and second side panels 110, 120, the top cover 130 extends beyond the extended section 172, allowing the extended section 172 to extend into the top cover 130, with the cover edge of the top cover 130 abutting the step 173. In one embodiment, the outer surface of the side wall of the top cover 130 is flush with the outer surface of the step 173, that is, the outer surface of the side wall of the top cover 130 is flush with the outer surface of the panel body 171. This improves the aesthetic appearance of the compressor cover 100 and the aesthetic appearance of the noise reduction structure.

[0063] In one embodiment, see Figure 5 The extending section 172 is provided with a guide structure at the end away from the plate body 171. The guide structure is configured as an inwardly inclined guide flange 174. The provision of the guide flange 174 provides precise guidance for the connection between the top cover 130 and the first and second side panels 110, 120, thereby improving the connection speed of the top cover 130, the first and second side panels 110, 120, and the assembly efficiency of the compressor cover 100.

[0064] In one embodiment, multiple guide flanges 174 are provided, and the multiple guide flanges 174 are spaced apart along the circumference of the compressor cover 100. Thus, a buffer groove 175 is formed between two adjacent guide flanges 174. The provision of the buffer groove 175 allows the guide flanges 174 to have a certain degree of deformation force, thereby facilitating the installation of the top cover 130 on the first and second side panels 110, 120, and reducing the matching precision requirements between the top cover 130, the first and second side panels 110, 120, thereby improving the ease of assembly and disassembly of the top cover 130, the first and second side panels 110, 120.

[0065] In one embodiment, see Figure 1 The first side panel 110 and the top cover 130 are connected by bolts, and / or the second side panel 120 and the top cover 130 are connected by bolts; and / or, in the circumferential direction of the compressor cover 100, the length of one of the first side panel 110 and the second side panel 120 is greater than the length of the other.

[0066] Specifically, after the first and second side panels 110 and 120 are fastened together, the top cover 130 is placed over the first and second side panels 110 and 120. To enhance the connection stability between the first and second side panels 110 and 120, connection holes are provided in the first and second side panels 110 and 120, respectively. Bolts are inserted through the holes to connect the first and second side panels 110 and 120. To enhance the connection stability between the second and second side panels 120 and 120, connection holes are provided in the second and second side panels 120 and 120, respectively. Bolts are inserted through the holes to connect the second and second side panels 120 and 120, respectively. Furthermore, the shape and size of the first and second side panels 110 and 120 can be adjusted according to the configuration of the compressor; they can be the same size or different sizes.

[0067] In the embodiment shown in the drawings of the present invention, the length of the first side panel 110 is greater than that of the second side panel 120 in the circumferential direction of the compressor cover 100. In this case, the first side panel 110 can be connected to the top cover 130 using two screws, while the second side panel 120 can be connected to the top cover 130 using one screw. Once the screws are locked, the components of the noise reduction structure cannot move relative to each other, ensuring a strong connection. Pins 180 can be provided on each of the three sides of the first side panel 110 to engage with the chassis 300. Since the multiple hooks 121 of the second side panel 120 engage with the multiple slots 111 on the first side panel 110, the first and second side panels 110, 120, are connected together. In this case, the pins 180 do not need to be provided on the second side panel 120.

[0068] In this way, the first side panel 110, the second side panel 120, and the top cover 130 are detachably connected through snap-fitting, while the screw fastening improves the stability and reliability of the connection. In one embodiment, the three components can be fastened with only three screws, reducing the number of screws used, saving screw fastening time, and improving assembly efficiency.

[0069] In one embodiment, see Figure 1 The lower end of the compressor cover 100 has an opening 140, and the noise reduction structure also includes a base 160 provided in the opening 140. The base 160 is mounted on the chassis 300. The material of the base 160 is configured as an elastic member, and the base 160 is used to install the compressor. In this way, the provision of the elastic member helps to reduce the transmission of compressor vibration to the outside. In one embodiment, the elastic member is configured as rubber.

This facilitates installation of the compressor cover 100 and the sound insulation.

[0071] In the embodiments of the present invention, please refer to Figure 1 The air conditioner further includes an air duct housing 400 mounted on the chassis 300. The air duct housing 400 is arranged side by side with the compressor cover 100 and is connected to the first side panel 110. Compared to connecting the air duct housing 400 to the top cover 130, connecting the air duct housing 400 to the first side panel 110 improves the stability of the connection between the air duct housing 400 and the compressor cover 100. In one embodiment, the air duct housing 400 and the first side panel 110 are detachably connected, thereby facilitating the inspection, maintenance, and replacement of the air duct housing 400, the compressor cover 100, and the compressor.

[0072] In the embodiments of the present invention, please refer to Figure 5 The duct housing 400 is provided with a stopper pin 410, and the first side panel 110 is provided with a stopper hole 114. The stopper pin 410 is inserted into the stopper hole 114 to connect the duct housing 400 and the first side panel 110. When connecting the duct housing 400 and the first side panel 110, the stopper hole 114 is positioned outside the stopper pin 410, thereby securing the first side panel 110 to the duct housing 400. The stopper pin 410 serves as the main load-bearing structure, limiting the front, back, left, and right positions of the compressor cover 100.

[0073] In the embodiments of the present invention, please refer to Figure 5 The duct housing 400 has a first connection hole 420 formed near the stop pin 410, and the first side panel 110 has a second connection hole 115 formed near the stop hole 114. A connecting member passes through the first connection hole 420 and the second connection hole 115 to connect the duct housing 400 and the first side panel 110. Specifically, to improve the connection reliability between the duct housing 400 and the compressor cover 100, the first connection hole 420 is formed near the stop pin 410 on the duct housing 400, and the second connection hole 115 is formed near the stop hole 114 on the first side panel 110. The position of the second connection hole 115 corresponds to the first connection hole 420. A connecting member, such as a bolt, passes through the first connection hole 420 and the second connection hole 115 in sequence, thereby connecting the duct housing 400 and the first side panel 110 together, thereby improving the stability of the front-to-back and left-to-right limiting of the compressor cover 100.

[0074] In the embodiments of the present invention, please refer to Figure 2 and Figure 3 A first mounting hole 116 is provided on the first side panel 110, and a first through hole 331 is adapted to be provided on the chassis 300. The connecting member passes through the first mounting hole 116 and the first through hole 331 to connect the first side panel 110 and the chassis 300; a second mounting hole 125 is provided on the second side panel 120, and a second through hole 332 is adapted to be provided on the chassis 300. The connecting member passes through the second mounting hole 125 and the second through hole 332 to connect the second side panel 120 and the chassis 300.

[0075] Specifically, the first side panel 110 and the second side panel 120 are clamped together, and the first side panel 110 and the chassis 300 are clamped together through the pin 180 and the slot 310. In order to improve the connection stability between the compressor cover 100 and the chassis 300, a screw is used to lock the first side panel 110 and the chassis 300, and a screw is used to lock the second side panel 120 and the chassis 300, thereby limiting the compressor cover 100 in the up and down directions.

[0076] In one embodiment, compared to a structure that requires an additional flange on the compressor cover 100 and then provides mounting holes in the flange, the present invention directly provides first mounting holes 116 and second mounting holes 125 on the first side panel 110 and second side panel 120, respectively. This allows for precise hole opening and facilitates alignment with the through-holes on the chassis 300. Furthermore, the first through-holes 331 and second through-holes 332 on the chassis 300 are both located on the side of the chassis 300, facilitating production line operation without interfering with existing structures.

[0077] In one embodiment, when assembling the chassis 300, the compressor cover 100 and the duct housing 400, the duct housing 400 is first installed on the chassis 300, then the base 160 is inserted into the chassis 300, and then the first side panel 110 is installed on the chassis 300. At this time, it is necessary to ensure that the limiting hole 114 on the first side panel 110 is inserted outside the limiting pin 410 of the duct housing 400, and the three pins 180 at the lower end of the first side panel 110 are respectively inserted into the three slots 310 of the chassis 300. A screw is passed through the first connecting hole 420 on the duct housing 400 and the second connecting hole 115 on the first side panel 110 to lock the duct housing 400 and the first side panel 110; a screw is passed through the first mounting hole 116 on the first side panel 110 and the first through hole 331 on the chassis 300 to lock the first side panel 110 and the chassis 300. The second side panel 120 is then snapped onto the first side panel 110, and a screw is inserted through the second mounting hole 125 on the second side panel 120 and the second through-hole 332 on the chassis 300 to secure the second side panel 120 to the chassis 300. Finally, the top cover 130 is placed over the first and second side panels 110, 120, completing the assembly of the chassis 300, compressor cover 100, and duct housing 400. In this air conditioner, the various components are connected through snap-fit and screw-fitting. Only three screws are used throughout the entire structure to achieve a stable and secure connection. Compared to methods using multiple screws, this significantly reduces the number of screws used, thereby reducing the time required for screw fastening and improving assembly efficiency.

[0078] In the embodiments of the present invention, please refer to Figure 1 The compressor cover 100 is connected to a wiring harness fixture 190 for securing the air conditioner's wiring harness. The wiring harness fixture 190 facilitates the straightening and securing of the air conditioner's wiring harness, facilitates wiring harness management and maintenance, and improves the aesthetics of wiring.

[0079] In one embodiment, the harness fixing member 190 is configured as a flexible metal strip. The flexible metal strip can be deformed to clamp the harness, facilitating harness fixation. However, the present invention is not limited thereto. In other embodiments, the harness fixing member 190 may also be a binding band, a cable tie, or the like.

[0080] In one embodiment, the flexible metal strip is coated with an adhesive layer. This adhesive layer improves the feel of the wire harness fixture 190, prevents accidental injury to the user, and prevents wear and tear on the wire harness. In one embodiment, the adhesive layer is configured as a silicone layer, a rubber layer, or the like.

[0081] In an embodiment of the present invention, the air conditioner includes an indoor air conditioner unit and an outdoor air conditioner unit; wherein, the indoor air conditioner unit includes a chassis 300; and / or, the indoor air conditioner unit and the outdoor air conditioner unit are connected through a flexible refrigerant pipe, and the flexible refrigerant pipe is pre-filled with refrigerant.

[0082] The air conditioner of the present invention can be a split-type air conditioner for easy user installation. The indoor unit includes a chassis 300, on which a compressor is mounted. This arrangement reduces the weight of the outdoor unit and facilitates installation. Accordingly, the compressor is located within the indoor unit, and to ensure comfortable operation and low noise interference, a noise reduction mechanism is required for the compressor.

[0083] The air conditioner uses a flexible refrigerant pipe to connect the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit. Refrigerant is injected into the refrigerant circuit before the unit leaves the factory. This allows users to install the unit themselves by simply securing the indoor and outdoor units separately, eliminating the need to assemble refrigerant pipes or add refrigerant. This reduces installation complexity and facilitates user-friendly installation. However, the present design is not limited to this. In other embodiments, the air conditioner of the present invention can also be a conventional split-type air conditioner.

[0084] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention.
