[0016] In some embodiments of the present disclosure, an air conditioner is provided.

[0017] As shown in FIG. 1 , the air conditioner 1000 includes an indoor unit 10 and an outdoor unit 20. The indoor unit 10 and the outdoor unit 20 are connected by piping to transmit a refrigerant. The indoor unit 10 includes an indoor heat exchanger 400 and an indoor fan 600. The outdoor unit 20 includes a compressor 201, a four-way valve 202, an outdoor heat exchanger 203, an outdoor fan 204, and an expansion valve 205. The compressor 201, the outdoor heat exchanger 203, the expansion valve 205, and the indoor heat exchanger 400, which are connected in order, form a refrigerant circuit, and the refrigerant circulates within the refrigerant circuit and exchanges heat with air via the outdoor heat exchanger 203 and the indoor heat exchanger 400, respectively, thereby realizing the cooling mode or the heating mode of the air conditioner 1000.

[0018] The compressor 201 is configured to compress a refrigerant, thereby compressing a low-pressure refrigerant to form a high-pressure refrigerant.

[0019] The outdoor heat exchanger 203 is configured to exchange heat between outdoor air and the refrigerant transmitted within the outdoor heat exchanger 203. For example, in the cooling mode of the air conditioner 1000, the outdoor heat exchanger 203 operates as a condenser, and the refrigerant compressed by the compressor 201 condenses by releasing heat to the outdoor air through the outdoor heat exchanger 203. In the heating mode of the air conditioner 1000, the outdoor heat exchanger 203 operates as an evaporator, and the refrigerant after decompression absorbs heat from the outdoor air through the outdoor heat exchanger 203 and evaporates.

[0020] In some embodiments, the outdoor heat exchanger 203 further includes heat exchange fins, which increase the contact area between the outdoor air and the refrigerant transported within the outdoor heat exchanger 203 and improve the heat exchange efficiency between the outdoor air and the refrigerant.

[0021] The outdoor fan 204 is configured to draw outdoor air into the outdoor unit 20 through the outdoor air inlet of the outdoor unit 20, and send the outdoor air that has exchanged heat with the outdoor heat exchanger 203 out through the outdoor air outlet of the outdoor unit 20. The outdoor fan 204 supplies power to the flow of outdoor air.

[0022] The expansion valve 205 is connected between the outdoor heat exchanger 203 and the indoor heat exchanger 400, and the pressure of the refrigerant flowing between the outdoor heat exchanger 203 and the indoor heat exchanger 400 is adjusted by the opening degree of the expansion valve 205, thereby adjusting the flow rate of the refrigerant flowing between the outdoor heat exchanger 203 and the indoor heat exchanger 400. The flow rate and pressure of the refrigerant flowing between the outdoor heat exchanger 203 and the indoor heat exchanger 400 affect the heat exchange performance of the outdoor heat exchanger 203 and the indoor heat exchanger 400. The expansion valve 205 may be an electronic valve. The opening degree of the expansion valve 205 is adjustable, thereby controlling the flow rate and pressure of the refrigerant flowing through the expansion valve 205.

[0023] The four-way valve 202 is connected in the refrigerant circuit, and is configured to switch the flow direction of the refrigerant in the refrigerant circuit to cause the air conditioner 1000 to operate in a cooling mode or a heating mode.

[0024] The indoor heat exchanger 400 is configured to exchange heat between indoor air and the refrigerant transferred within the indoor heat exchanger 400. For example, in the cooling mode of the air conditioner 1000, the indoor heat exchanger 400 operates as an evaporator, and the refrigerant that has released heat through the outdoor heat exchanger 203 absorbs heat from the indoor air through the indoor heat exchanger 400 and evaporates. In the heating mode of the air conditioner 1000, the indoor heat exchanger 400 operates as a condenser, and the refrigerant that has absorbed heat through the outdoor heat exchanger 203 releases heat to the indoor air through the indoor heat exchanger 400 and condenses.

[0025] In some embodiments, the indoor heat exchanger 400 further includes heat exchange fins, which increase the contact area between the indoor air and the refrigerant transported within the indoor heat exchanger 400 and improve the heat exchange efficiency between the indoor air and the refrigerant.

[0026] The indoor fan 600 is configured to draw indoor air into the indoor unit 10 through the indoor air inlet of the indoor unit 10, and send out the indoor air that has exchanged heat with the indoor heat exchanger 400 through the indoor air outlet 12 of the indoor unit 10. The indoor fan 600 supplies power to the flow of indoor air.

[0027] For convenience of explanation, unless otherwise specified, the present disclosure refers to the direction expressions up, down, left, right, front, and rear with reference to the state when the air conditioner 1000 is in use. The side of the air conditioner 1000 that faces the user when in use is the front side, and the opposite side is the rear side. The height direction of the air conditioner 1000 is the up-down direction. The left-right direction of the air conditioner 1000 is opposite to the left-right direction of the user; for example, the left side of the air conditioner 1000 is the user's right side, and the right side of the air conditioner 1000 is the user's left side.

[0028] To introduce fresh air into a room, a fresh air device is typically integrated into an indoor unit, which increases the volume of the indoor unit and occupies a large amount of indoor space. Furthermore, installing a filter assembly on the indoor unit can easily cause secondary pollution inside the room when the filter assembly is removed. Alternatively, when a fresh air device is installed on an outdoor unit, the compressor inside the outdoor unit generates large vibrations during operation, which are transmitted directly to the fresh air device, making the volute housing and air guide duct inside the fresh air device susceptible to vibration and causing shaking, which in turn affects the airflow volume and reduces the operational stability of the fresh air device to some extent.

[0029] To solve the above problems, the present disclosure provides a fresh air device mounted on an outdoor unit, a filtration assembly removably mounted within the fresh air device, and additionally provides an elastic connector at the connection between the volute housing main body and the housing, and an additional buffer pad at the connection between the air guide duct and the housing, thereby reducing the impact of vibration on the volute housing main body and the outlet duct, thereby ensuring stable operation of the fresh air device. As shown in FIGS. 2 to 5 , an air conditioner 1000 further includes a fresh air device 100, which is mounted on an outdoor unit 20. The fresh air device 100 includes a housing 1, a filtration assembly 2, an electrical control assembly 3, and a suction assembly 4. The housing 1 includes a base 14 and an upper cover 15. The housing 1 has an inlet 11, an outlet 12, and an insertion port 13. The inlet 11, the outlet 12, and the insertion port 13 are each openly installed on the base 14. Inlet 11 and outlet 12 are provided on a first side and a second side of housing 1, respectively, and the first side and the second side face each other. For example, when inlet 11 is located on the right side of base 14, outlet 12 is located on the left side of base 14. Insertion opening 13 is located near inlet 11 on a third side (for example, the front side) of housing 1.

[0030] As shown in FIG. 3 , the outdoor unit 20 further includes a case 206. A first opening 207 is provided at the top of the case 206. Of course, the top of the case 206 may be sealed. If the first opening 207 is provided at the top of the case 206, the fresh air device 100 is attached to the top of the case 206 and fits over the first opening 207 of the case. That is, the fresh air device 100 is integrated into the outdoor unit 20, and the upper structure of the fresh air device 100 also forms the upper structure of the case 206, simplifying the overall structure of the outdoor unit 20. If the top of the case 206 is sealed, the fresh air device 100 is relatively independent from the outdoor unit 20, and the user can remove the fresh air device 100 according to actual needs without affecting the use of the air conditioner 100. In some embodiments, the air outlet 12 is provided on the housing 1 at a position close to the cavity where the compressor 201 is located inside the outdoor unit 20. For example, by arranging both the air outlet 12 and the compressor 201 on the left side of the housing 1, wiring can be made easier.

[0031] In some embodiments, as shown in FIGS. 4 and 5 , an open receiving groove 141 is provided on the top of the base 14. The filter assembly 2, the electrical control assembly 3, and the suction assembly 4 are sequentially mounted in the receiving groove 141 of the base 14 in a first direction (e.g., from right to left). The filter assembly 2 is slidably inserted into the housing 1 through the insertion opening 13, eliminating the need to remove the housing 1 before mounting or removing the filter assembly 2. The suction assembly 4 is located in the receiving groove 141 on a side closer to the air outlet 12. The electrical control assembly 3 is located between the filter assembly 2 and the suction assembly 4. The suction assembly 4 is coupled to the electrical control assembly 3. The suction assembly 4 draws in external air through the air inlet 11 and allows the external air to pass through the filter assembly 2 and flow out through the air outlet 12. The top cover 15 is mounted on the base 14 and covers the top of the receiving groove 141. For example, the upper cover 15 may be connected to the base 14 by providing a threaded post on the upper side edge of the base 14, providing a connection hole on the side end of the upper cover 15, and driving a screw into the side surface.

[0032] The fresh air device 100 is attached to the top of the outdoor unit 20 without occupying any indoor space. Because the fresh air device 100 is installed outdoors, the size of the indoor unit can be reduced, meeting the needs of Japanese users for compact indoor spaces and low noise. Furthermore, this disclosure focuses on the overall layout of the fresh air device 100; that is, the entire fresh air device 100 is located above the outdoor unit 20 and is externally formed as a single unit with the outdoor unit 20. Installing it in this manner increases the overall height of the outdoor unit 20 but not its length, making installation in a practical space easier. Installation requires only the installation of connecting ducts on both the indoor and outdoor sides; no other operations are required. In addition, the air intake 11, filter assembly 2, electrical control assembly 3, suction assembly 4, and air outlet 12 are installed in order from right to left in the fresh air device 100, which allows for rational use of horizontal space and fits the dimensions of the outdoor unit. The filter assembly 2 is installed by sliding into the housing 1 through an insertion port 13 at the front of the housing 1, making it easy to install and remove, making cleaning and replacement more convenient, and ensuring long-term filtering performance. Furthermore, by installing the filter assembly 2 inside the housing 1, it is possible to prevent erosion by light and rainwater, and also to avoid collision with foreign objects, thereby preventing damage and extending the lifespan. Furthermore, outdoor air flows in from the right side of the housing 1, is filtered and deodorized by the filter assembly 2, and then is sent into the room from the left side of the housing 1. The outdoor air ensures smooth gas flow through left and right convection within the housing 1, preventing phenomena such as vortexes from forming inside the housing 1, and guarantees the amount of intake air and ventilation efficiency.

[0033] In some embodiments, as shown in FIGS. 4 and 5 , the fresh air device 100 further includes a ventilation bracket 5, which is installed between the suction port 11 and the electric control assembly 3. For example, the ventilation bracket 5 and the base 14 may be detachably connected by engagement or screw fastening. The ventilation bracket 5 may be used to transport gas entering through the suction port 11 to the filter assembly 2. As shown in FIG. 5 , the ventilation bracket 5 includes an suction passage 51. The suction passage 51 has an suction end 511 and an outlet end 512. The suction end 511 is located on the suction passage 51 closer to the suction port 11 and is connected to the suction port 11, and the outlet end 512 is located on the suction passage 51 closer to the electric control assembly 3. The ventilation bracket 5 includes a passage opening 52. The passage opening 52 is located on the front side of the ventilation bracket 5 near the insertion opening 13, and the passage opening 52 communicates with the interior of the suction passage 51. The filter assembly 2 passes through the insertion port 13 and the passage port 52 in order, and then is slidably inserted into the suction passage 51. Under the action of the suction assembly 4, fresh air from the outdoor side passes through the suction port 11 and the suction end 511 in order, enters the suction passage 51, is filtered by the filter assembly 2, and finally flows out from the air outlet 12 into the indoor side.

[0034] As shown in FIGS. 8 and 11 , the ventilation bracket 5 further includes a plurality of guide rib plates 53. The plurality of guide rib plates 53 are provided on the inner wall of the suction passage 51 near the suction end 511, and are arranged in order along a direction perpendicular to the bottom surface of the housing 1 (e.g., the up-down direction). The plurality of guide rib plates 53 are provided at an incline; for example, the plurality of guide rib plates 53 are provided at an incline toward one side of the suction port 11. For example, the inclination angle of the guide rib plates 53 may be 30 to 45 degrees. Installing the inclined guide rib plates 53 at the suction end 511 can effectively reduce the intrusion of rainwater into the suction passage 51 and ensure the smooth passage of fresh air.

[0035] As shown in FIG. 8, the ventilation bracket 5 further includes a plurality of suction grilles 111. The plurality of suction grilles 111 are provided on the inner wall of the suction passage 51 on the side closer to the suction end 511. The plurality of suction grilles 111 are arranged in order along the vertical direction of the suction end 511. As shown in FIG. 8, the suction grilles 111 and the guide rib plate 53 are connected to each other in an overlapping manner. The suction grilles 111 ensure a good fitting connection between the suction port 11 and the suction end 511, and can prevent rainwater from entering the housing 1.

[0036] In some embodiments, as shown in FIGS. 7 to 12 , the suction passage 51 further includes an air passage cavity 513, a filtering cavity 514, and an air passage gap 515. The air passage cavity 513 is located on a side of the suction passage 51 closer to the suction end 511. The air passage cavity 513 is used to circulate airflow. The filtering cavity 514 is located on a side of the suction passage 51 closer to the outlet end 512. The air passage cavity 513 communicates with the filtering cavity 514. As shown in FIGS. 8 and 9 , the ventilation bracket 5 further includes a water stop 5131. The water stop 5131 is located on a side of the air passage cavity 513 closer to the suction end 511. The water stop 5131 separates the suction end 511 and the filtering cavity 514. For example, the water stop 5131 may be installed along the vertical direction of the housing 1. The upper side of the water stop 5131 may be connected to the upper side of the suction passage 51 , and the lower side of the water stop 5131 may be connected to the base 14 .

[0037] 10 and 12, air passage gaps 515 are provided between the water stop 5131 and both front and rear wall surfaces of the air passage cavity 513. The air passage gaps 515 are used to circulate air. The filter assembly 2 is inserted into the filter cavity 514, and the filter cavity 514 is used to accommodate the filter assembly. In the intake passage 51, rainwater in the fresh air flows downward along the water stop 5131 while colliding with the water stop 5131, and after removing the rainwater, the fresh air continues to flow forward from the air passage gaps 515 to the filter assembly 2, performing filtering.

[0038] As shown in FIG. 14, the bottom surface of the base 14 further has a drain hole 142. The drain hole 142 is used to drain pools of water inside the housing 1. For example, the drain hole 142 may be connected to a cavity in which the fan of the outdoor unit 20 is located. Water droplets on the water stop plate 5131 flow downward and are discharged downward through the drain hole 142 into the cavity in which the outdoor fan 204 of the outdoor unit 20 is located.

[0039] 8 and 13, the base 14 further includes a water collection groove 148. The water collection groove 148 is provided on the bottom surface of the receiving groove 141 of the base 14, and the drainage hole 142 is provided in the water collection groove 148. The water collection groove 148 serves to collect water, and allows residual water in the air passage cavity 513 to be discharged downward.

[0040] 8 and 13, the housing 1 further includes a water blocking part 147. The water blocking part 147 is provided on the bottom surface of the mounting groove 1461 and is located between the ventilation bracket 5 and the electrical control assembly 3, which further prevents rainwater from flowing into the mounting position of the electrical control assembly 3 and avoids the occurrence of electrical leakage.

[0041] As shown in FIGS. 5, 7, and 13, the housing 1 further includes a partition plate 143. The partition plate 143 is installed in the receiving groove 141 of the base 14 and is located between the ventilation bracket 5 and the electrical control assembly 3. For example, the partition plate 143 is located between the water stopper 147 and the electrical control assembly 3. When the filtering assembly 2 is removed, the partition plate 143 prevents fingers from reaching the filtering cavity 514 and accidentally touching the electrical control assembly 3, thereby preventing electric shock.

[0042] In some embodiments, as shown in FIGS. 6, 7, and 13, the housing 1 further includes a support base 144 and a support plate 145. The support base 144 is installed in the receiving groove 141 of the base 14 and is located between the electric control assembly 3 and the suction assembly 4. An air passage 1441 is provided in the support base 144. The air passage 1441 is used for circulating air. The support plate 145 is installed in the receiving groove 141 of the base 14 and is installed on a side of the suction assembly 4 closer to the upper cover 15 (e.g., above the upper cover 15). Both ends of the support plate 145 are detachably connected to the base 14. The ventilation bracket 5, the support base 144, and the support plate 145 together serve to support the upper cover 15.

[0043] In some embodiments, as shown in FIGS. 13 and 14 , the suction assembly 4 includes a volute housing 41, a motor 42, an elastic connector 43, and a buffer pad 44. The volute housing 41 includes a volute housing main body 411 and an air guide duct 412. As shown in FIG. 7 , the volute housing main body 411 is installed in the receiving groove 141. An open air intake port 4111 is installed on the volute housing main body 411. One end of the air guide duct 412 communicates with the volute housing main body 411. For example, the air guide duct 412 and the volute housing main body 411 are integrally molded members. The other end of the air guide duct 412 communicates with the air outlet 12. The elastic connector 43 is provided on the volute housing main body 411 and connected to the base 14. The elastic connector 43 is used to reduce the amplitude of the volute housing main body 411. 22 , the buffer pad 44 is fitted onto the outer periphery of the air guide duct 412. The buffer pad 44 is used to reduce the amplitude of the air guide duct 412. The air guide duct 412 is connected to the base 14 via the buffer pad 44. The motor 42 is attached to the volute housing main body 411, and the output shaft of the motor extends into the volute housing main body 411.

[0044] In some embodiments, as shown in FIGS. 13 , 14 , and 18 , the suction assembly 4 further includes a ventilation joint 45. The ventilation joint 45 is hollow and has open ends. One end of the ventilation joint 45 passes through the air outlet 12 from the outside of the housing 1 to the inside of the housing 1. The ventilation joint 45 is fitted onto the outer periphery of the air guide duct 412 with a gap therebetween. The inner diameter of the ventilation joint main body 451 is larger than the outer diameter of the air guide duct 412. That is, the ventilation joint 45 does not directly contact the air guide duct 412. For example, a gap of about 2 mm may be provided between the inner wall of the ventilation joint 45 and the outer periphery of the air guide duct 412, and the ventilation joint 45 abuts against the end face of the buffer pad 44, which seals the gap between the inner wall of the ventilation joint 45 and the outer periphery of the air guide duct 412. The outside of the volute housing 41 is connected to the piping via a ventilation joint 45, improving the connection seal between the volute housing 41 and the piping, so that fresh air generated by the fresh air device 100 is smoothly sent into the room through the piping.

[0045] 18, the ventilation joint 45 further includes a ventilation joint main body 451 and a connecting plate 452. The connecting plate 452 is located on the outer periphery of the ventilation joint main body 451, and the connecting plate 452 is connected to the outer surface of the base 14. For example, the connecting plate 452 may be detachably connected to the outer wall of the housing 1 by screws, engagement, or the like, thereby fixing the ventilation joint main body 451 to the housing 1 and preventing the ventilation joint 45 from shaking due to vibration during use, thereby improving connection stability.

[0046] 13 to 18, the fresh air device 100 further includes a mounting seat 146. The mounting seat 146 is installed in a position close to the air outlet 12 in the receiving groove 141 of the base 14.

[0047] In some embodiments, as shown in FIG. 15 , the mounting seat 146 has a mounting groove 1461. The underside of the buffer pad 44 is fitted into the mounting groove 1461 and is attached to the inner wall of the mounting groove 1461. The mounting seat 146 is used to fix the mounting groove 1461. The dimension of the buffer pad 44 along its axial direction is larger than the width of the mounting groove 1461, so that the buffer pad 44 is fitted into the mounting groove 1461 by an interference fit, thereby fixing the buffer pad 44 in the mounting groove 1461. As shown in FIGS. 21 and 22 , the suction assembly 4 further includes a clamp 46. The clamp 46 abuts against the upper side of the buffer pad 44 and is connected to the mounting seat 146. The clamp 46 and the mounting groove 1461 form a mounting passage, through which the air guide duct 412 is installed. The clamp 46 is used to direct the air duct 412 upward and restrict separation from the volute housing main body 411, so that the air duct 412 is stably fixed in the housing 1.

[0048] In some embodiments, the elastic connector 43 and the buffer pad 44 may be made of a material such as rubber or silicone, which has a stronger elastic potential energy and can absorb vibrations transmitted to the housing 1 or generated by the suction assembly 4.

[0049] By installing the elastic connector 43 between the air duct 412 and the base 14 and the buffer pad 44 between the volute housing main body 411 and the base 14, rigid contact between the volute housing main body 411 or the ventilation joint 45 and the base 14 is avoided. On the one hand, the impact of vibrations generated during operation of the suction assembly 4 on the base 14 and the ventilation joint 45 is reduced, preventing resonance noise. On the other hand, the impact of vibrations transmitted from the compressor 201 to the housing 1 on the suction assembly 4 is reduced, thereby improving the connection stability of the suction assembly 4 within the housing 1, thereby ensuring stable blowing and improving the operational stability of the air freshener 100. Furthermore, the buffer pad 44 elastically abuts against the end of the ventilation joint 45, providing sealing and joining functions. In some embodiments, as shown in FIG. 15 , the mounting seat 146 further includes an insertion groove 1462 and a screw hole 1463. The insertion groove 1462 and the screw hole 1463 are respectively provided at both ends of the mounting groove 1461. One end of the clamp 46 may be inserted into the insertion groove 1462, and the other end of the clamp 46 may be connected to the threaded hole 1463 via a screw. The mounting seat 146 is also used to secure the clamp 46. The process of attaching the clamp 46 and the mounting seat 146 may be as follows: First, one end of the clamp 46 is inserted into the insertion groove 1462. For example, the connection between the end of the clamp 46 and the insertion groove 1462 may be by an interference fit or engagement. The connection between the clamp 46 and the insertion groove 1462 positions the clamp 46. Next, the other end of the clamp 46 is connected to the threaded hole 1463. For example, a screw and the threaded hole 1463 may be used to thread the clamp 46 and the threaded hole 1463. The connection between the clamp 46 and the threaded hole 1463 secures the clamp 46. This improves assembly convenience between the clamp 46 and the mounting seat 146.

[0050] 19 and 20 , the housing 1 further includes a groove 121. The groove 121 is provided along the outer periphery of the air outlet 12 and is located outside the housing 1. The connecting plate 452 is provided in the groove 121 to fix the ventilation joint main body 451. The groove 121 is fitted with the connecting plate 452 to achieve positioning, improving the ease of assembly of the ventilation joint 45 on the housing 1.

[0051] In some embodiments, as shown in FIGS. 17 and 19 , the fresh air device 100 further includes a mounting post 149. The mounting post 149 is installed on the bottom surface of the receiving groove 141. For example, the mounting post 149 may be an integrally molded member with the housing 1. The elastic connector 43 is installed by fitting onto the mounting post 149. The mounting post 149 is used to fix the elastic connector 43. As shown in FIG. 13 , the spiral housing 41 further includes a plurality of connecting rings 413. The plurality of connecting rings 413 are installed on the outer periphery of the spiral housing main body 411. For example, the plurality of connecting rings 413 may be an integrally molded member with the spiral housing main body 411. A plurality of locking grooves are provided on the outer periphery of the elastic connector 43. The connecting rings 413 are installed by fitting into the locking grooves of the elastic connector 43. For example, the connecting ring 413 is installed by being fitted into the annular locking groove by an interference fit, so that the spiral housing main body 411 is stably fixed inside the case 1.
