Of course, the embodiments described here are only a part of the embodiments of the present disclosure, not all embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art shall be included in the protection scope of the present disclosure.

[0008] Unless otherwise indicated in the context, in this specification and the claims, the term "comprise" and its other forms, for example, the third-person singular form "comprises" and the present participle form "comprising", should be interpreted in an open, inclusive sense, that is, "including but not limited to these". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example", or "some examples", etc., are intended to indicate that a specific feature, structure, material, or characteristic related to this embodiment or its example is included in at least one embodiment or example of the present disclosure.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present disclosure, unless otherwise specified, "a plurality" means two or more.

[0010] When describing some embodiments, the terms "coupled" and "connected" and their derived expressions may be used. The term "connected" should be understood in a broad sense. For example, "connected" may be a fixed connection, a removable connection, or may be integrated, may be a direct connection, or may be an indirect connection through an intermediate medium. The term "coupled" indicates that two or more components have direct physical or electrical contact with each other. The term "coupled" or "communicatively coupled" may also mean that two or more components do not directly contact each other but still cooperate or interact with each other.

[0012] "A and / or B" includes three combinations: only A, only B, and the combination of A and B.

[0013] In this specification, the use of "applied to..." or "arranged to..." means open and inclusive language and does not exclude an apparatus that is applied or arranged to perform additional tasks or steps.

[0014] As used herein, "about," "approximately," or "substantially" includes the recited value and the average value within an acceptable deviation range of the recited value, where the acceptable deviation range is determined in consideration of errors associated with the measurements being considered by one of ordinary skill in the art and the measurements of the particular quantities (i.e., the limitations of the measurement system).

[0015] As used herein, "parallel," "perpendicular," and "equal" include the described situation and situations approximating the described situation, where the range of the approximating situation is within an acceptable deviation range, and the acceptable deviation range is determined in consideration of errors associated with the measurements being considered by one of ordinary skill in the art and the measurements of the particular quantities (i.e., the limitations of the measurement system).

[0016] Some embodiments of the present disclosure provide an air conditioner.

[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 pipes to transmit 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 connected in sequence form a refrigerant circuit, and the refrigerant circulates in the refrigerant circuit and exchanges heat with air through 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 the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0019] The outdoor heat exchanger 203 is configured to exchange heat between the 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 dissipates heat to the outdoor air through the outdoor heat exchanger 203 and condenses. In the heating mode of the air conditioner 1000, the outdoor heat exchanger 203 operates as an evaporator, and the depressurized refrigerant absorbs the heat of 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, thereby expanding the contact area between the outdoor air and the refrigerant transmitted within the outdoor heat exchanger 203 and improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0021] The outdoor fan 204 is configured to suck outdoor air into the outdoor unit 20 through the outdoor suction port of the outdoor unit 20 and send out the outdoor air that has exchanged heat with the outdoor heat exchanger 203 through the outdoor blowout port of the outdoor unit 20. The outdoor fan 204 supplies power to the flow of the outdoor air.

[0022] The expansion valve 205 is connected between the outdoor heat exchanger 203 and the indoor heat exchanger 400. The pressure of the refrigerant flowing through the outdoor heat exchanger 203 and the indoor heat exchanger 400 is adjusted by the opening degree of the expansion valve 205, so that the flow rate of the refrigerant flowing between the outdoor heat exchanger 203 and the indoor heat exchanger 400 is adjusted. 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. Since the opening degree of the expansion valve 205 is adjustable, the flow rate and pressure of the refrigerant flowing through the expansion valve 205 are controlled.

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

[0024] The indoor heat exchanger 400 is configured to exchange heat between indoor air and the refrigerant transmitted 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 dissipated heat through the outdoor heat exchanger 203 absorbs the heat of 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 dissipates 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, thereby expanding the contact area between the indoor air and the refrigerant transmitted within the indoor heat exchanger 400 and improving the heat exchange efficiency between the indoor air and the refrigerant.

[0026] The indoor fan 600 is configured to suck indoor air into the indoor unit 10 through the indoor suction port 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 the indoor air.

[0027] For the sake of convenience in description, unless otherwise specified, in this disclosure, regarding the orientation expressions of up, down, left, right, front, and back, the state during the use of the air conditioner 1000 is used as a reference. The side facing the user during the use of the air conditioner 1000 is the front side, and the opposite side is the rear side. The height direction of the air conditioner 1000 is the vertical direction. The left and right directions of the air conditioner 1000 are opposite to the left and right directions of the user. For example, the left side of the air conditioner 1000 is the right side of the user, and the right side of the air conditioner 1000 is the left side of the user.

[0028] In order to introduce fresh air into the indoor space, it is common to integrate a fresh air device into the indoor unit. As a result, the volume of the indoor unit becomes large, occupying the indoor space. In addition, by installing a filtration assembly inside the indoor unit, secondary pollution is likely to occur indoors when the filtration assembly is removed. Alternatively, a fresh air device is attached to the outdoor unit, but external rainwater and the like are likely to enter the fresh air device through the suction port, so there is a risk of leakage to the charged parts inside the fresh air device, and the service life of the fresh air device may be reduced.

[0029] Moreover, since the suction air volume and ventilation efficiency of the fresh air device are low, the suction effect of fresh air entering the room is low. Furthermore, it is troublesome to attach and detach the filtration and deodorization assembly to and from the fresh air device, and it is difficult to disassemble, clean, and replace the filtration and deodorization assembly, resulting in a degraded user experience.

[0030] To solve the above problems, the present disclosure attaches a fresh air device to an outdoor unit, removably attaches a filtration assembly to the inside of the fresh air device through an insertion port, and further provides a locking tool and a locking groove, so that the removal or attachment of the filtration assembly can be easily performed manually, and the removal and attachment of the filtration assembly can be made more convenient. A guide rib plate, a suction grille, a water stop plate, and a water stop portion are installed on one side of the suction port, and the guide rib plate and the suction grille are overlapped and connected to each other to prevent rainwater from entering and reduce the risk of electric shock of the electric control assembly. Further, by providing the suction port and the air outlet facing each other on the left and right sides of the housing, the generation of vortex inside the housing is avoided, and the suction efficiency is guaranteed. As shown in FIGS. 2 to 6, the air conditioner 1000 further includes a fresh air device 100, and the fresh air device 100 is attached to the outdoor unit 20. The fresh air device 100 includes a housing 1, a filtration assembly 2, an electric control assembly 3, and a suction assembly 4. The housing 1 includes a base 14 and an upper cover 16. The housing 1 has a suction port 11, an air outlet 12, and an insertion port 13. The suction port 11, the air outlet 12, and the insertion port 13 are respectively opened and installed on the base 14. The suction port 11 and the air outlet 12 are respectively provided on the first side and the second side of the housing 1, and the first side and the second side face each other. For example, when the suction port 11 is located on the right side of the base 14, the air outlet 12 is located on the left side of the base 14. The insertion port 13 is located near the suction port 11 on the third side (for example, the front side) of the housing 1. The filtration assembly 2 is slidably inserted into the housing 1 through the insertion port 13, so that it is not necessary to remove the housing 1 to detach the filtration assembly 2, and it is easy for the filtration assembly 2 to be detached through the insertion port 13. By installing the filtration assembly 2 inside the housing 1, erosion by light and rainwater can be avoided, collision with foreign objects can also be avoided, damage can be prevented, and the service life can be extended. The electric control assembly 3 is installed inside the housing 1 and is located on the side away from the suction port 11 of the filtration assembly 2, thereby reducing the ingress of water into the electric control assembly 3. The suction assembly 4 is installed inside the housing 1 and is located on the side close to the air outlet 12 inside the housing 1. The suction assembly 4 is coupled to the electric control assembly 3, and the electric control assembly 3 is configured to control the operation of the suction assembly 4. The suction assembly 4 is used to suck external air from the suction port 11 and let the external air flow out from the air outlet 12 through the filtration assembly 2.

[0031] The fresh air device 100 is installed on the upper part of the outdoor unit 20 without occupying the indoor space. Also, in the fresh air device 100, the suction port 11, the filtration assembly 2, the electric control assembly 3, the suction assembly 4, and the air outlet 12 are installed in order along the direction from right to left, so that the horizontal space can be reasonably utilized, thus matching the dimensions of the outdoor unit. Also, the filtration assembly 2 is slidably inserted into the housing 1 through the insertion port 13 on the front side of the housing 1 for installation, which makes it easy to detach and attach, thereby making cleaning and replacement more convenient, ensuring long-term filtration effect, and improving the usage experience. Since the fresh air device 100 is installed outdoors, the size of the indoor unit can be reduced, meeting the needs of Japanese users for the compactness and low noise of the indoor space. Also, in the present disclosure, emphasis is placed 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 integrally formed with the outdoor unit 20 in appearance. By installing in this way, although the overall height of the outdoor unit 20 increases, the length does not increase, making the installation in the actual space easier. During installation, it is only necessary to install the connection ducts on both the indoor and outdoor sides, and no other operations are required.

[0032] At the same time, outdoor air flows in from the right side of the housing 1, and after being filtered and deodorized by the filtration assembly 2, it is sent into the room from the left side of the housing 1. The outdoor air ensures a smooth gas flow by means of left-right convection within the housing 1, avoiding phenomena such as the air generating a vortex within the housing 1, and guaranteeing the suction air volume and ventilation efficiency. The outdoor unit 20 further includes a box body 206. A first opening 207 is provided at the upper part of the box body 206. The fresh air device 100 is installed on the upper part of the box body 206 and is fitted to cover the first opening 207 of the box body. That is, the fresh air device 100 is integrally provided within the outdoor unit 20, and the upper structure of the fresh air device 100 simultaneously constitutes the upper structure of the box body 206, and the overall structure of the outdoor unit 20 can be simplified. In some embodiments, the upper part of the box body 206 may also be sealed, and the fresh air device 100 is relatively independent of 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 1000. Also, in some embodiments, the air outlet 12 is provided corresponding to the side close to the cavity where the compressor 201 is located within the outdoor unit 20 on the housing 1. For example, by arranging both the air outlet 12 and the compressor 201 on the left side of the housing 1, the wiring can be facilitated.

[0033] As shown in FIGS. 4, 5, and 6, a receiving groove 141 is provided open at the upper part of the base 14. The filtering assembly 2, the electric control assembly 3, and the suction assembly 4 are sequentially mounted in the receiving groove 141 of the base 14 in the first direction (for example, the direction from right to left). The upper cover 16 is mounted on the base 14 and covers the upper part of the receiving groove 141. For example, screw posts may be provided on the upper side edges of the base 14, connection holes may be provided at the side ends of the upper cover 16, and the upper cover 16 may be connected to the base 14 by screwing on the side surface.

[0034] In some embodiments, as shown in FIGS. 5 and 6, the fresh air device 100 further includes a ventilation bracket 5, and the ventilation bracket 5 is installed between the suction port 11 and the filtering assembly 2. The ventilation bracket 5 may be used to transport the external air entering from the suction port 11 to the filtering assembly 2. As shown in FIG. 6, the ventilation bracket 5 includes a suction passage 51. The suction passage 51 has a suction end 511 and a blowing end 512. The suction end 511 is located on the side closer to the suction port 11 of the suction passage 51, the suction end 511 is connected to the suction port 11, and the blowing end 512 is located on the side closer to the electric control assembly 3 of the suction passage 51. The ventilation bracket 5 has a through port 52. The through port 52 is provided on the front side closer to the insertion port 13 of the ventilation bracket 5, and the through port 52 communicates with the inside of the suction passage 51. The filtering assembly 2 is slidably inserted and installed in the suction passage 51 after sequentially passing through the insertion port 13 and the through port 52. Under the action of the suction assembly 4, the fresh air on the outdoor side enters the suction passage 51 through the suction port 11 and the suction end 511 in sequence, is filtered by the filtering assembly 2, and finally flows out to the indoor side from the air outlet 12.

[0035] In some embodiments, the assembly process of the fresh air device 100 may be as follows. First, the ventilation bracket 5, the electric control assembly 3, and the suction assembly 4 are fixedly installed in the accommodation cavity 161 respectively. Next, the upper cover 16 is attached to the upper part of the base 14 by bolts or engagement. Finally, the filtration assembly 2 is slidably inserted into the filtration cavity 514 of the ventilation bracket 5 from the insertion opening 13 on the front side of the base 14, thereby completing the assembly of the fresh air device 100 of the embodiment of the present application.

[0036] By installing the ventilation bracket 5 between the suction port 11 and the filtration assembly 2, the filtration assembly 2 can directly filter the air flowing into the housing 1, avoiding the accumulation of dust and odor molecules in the air inside the housing 1, maintaining the cleanliness inside the housing 1, and avoiding the generation of abnormal odors during the use process of the fresh air device 100 and affecting the filtration effect.

[0037] As shown in FIG. 14, 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 on the side close to the suction end 511 of the suction passage 51, and are arranged in sequence along the direction perpendicular to the bottom surface of the housing 1 (for example, the vertical direction). The plurality of guide rib plates 53 are provided obliquely. For example, the plurality of guide rib plates 53 are provided obliquely toward one side of the suction port 11. For example, the inclination angle of the guide rib plate 53 may be from 30 to 45°. Installing the inclined guide rib plate 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.

[0038] As shown in FIG. 9, the ventilation bracket 5 further includes a plurality of suction grills 111. The plurality of suction grills 111 are provided on the inner wall on the side close to the suction end 511 of the suction passage 51. The plurality of suction grills 111 are arranged in sequence along the vertical direction of the suction end 511. The suction grill 111 and the guide rib plate 53 are overlapped and connected to each other. The suction grill 111 can ensure a good fitting and joining effect between the suction port 11 and the suction end 511, and avoid the intrusion of rainwater into the housing 1.

[0039] In some embodiments, as shown in FIGS. 7 to 11, the suction passage 51 further has an air passage cavity 513, a filtration cavity 514, and an air passage gap 515. The air passage cavity 513 is located on the side closer to the suction end 511 of the suction passage 51. The air passage cavity 513 is used for the air flow to circulate. The filtration cavity 514 is located on the side closer to the blowing end 512 of the suction passage 51. The air passage cavity 513 communicates with the filtration cavity 514. As shown in FIGS. 8 and 9, the ventilation bracket 5 further includes a water stop plate 5131. The water stop plate 5131 is provided on the side closer to the suction end 511 in the air passage cavity 513. The water stop plate 5131 separates the suction end 511 from the filtration cavity 514. For example, the water stop plate 5131 may be installed along the vertical direction of the housing 1. The upper side of the water stop plate 5131 may be connected to the upper side of the suction passage 51, and the lower side of the water stop plate 5131 may be connected to the base 14.

[0040] As shown in FIGS. 11 and 13, air passage gaps 515 are provided between the water stop plate 5131 and both side wall surfaces of the front and rear of the air passage cavity 513. The air passage gaps 515 are used for the air flow to circulate. The filtration assembly 2 is inserted and installed in the filtration cavity 514, and the filtration cavity 514 is used to accommodate the filtration assembly 2. In the suction passage 51, the rainwater in the fresh air flows downward along the water stop plate 5131 during the collision with the water stop plate 5131. After removing the rainwater, the fresh air continues to flow forward from the air passage gap 515 to the filtration assembly 2 for filtration treatment.

[0041] In some embodiments, as shown in FIGS. 9 and 12, the housing 1 further includes a plurality of mounting posts 149. The plurality of mounting posts 149 are installed on the base 14. For example, the suction passage 51 includes two mounting posts 149, and the lower side of the water stop plate 5131 contacts the upper part of the mounting posts 149. That is, the water stop plate 5131 is installed in the suction passage 51, and there is also a ventilation interval between the bottom side of the water stop plate 5131 and the bottom wall surface of the suction passage 51.

[0042] In some embodiments, as shown in FIG. 12, the mounting post 149 includes a mounting post main body 1493 and an engaging portion 1491. The mounting post main body 1493 has a first connection hole 1492. The engaging portion 1491 is provided on the mounting post main body 1493. As shown in FIG. 13, the water stop plate 5131 has a positioning hole 5131A and a second connection hole 5131B. The positioning hole 5131A and the second connection hole 5131B are provided on the side of the water stop plate 5131 close to the mounting post main body 1493 (for example, the lower side). The positioning hole 5131A and the engaging portion 1491 are fitted and engaged with each other. By engaging the engaging portion 1491 and the positioning hole 5131A, the water stop plate 5131 is positioned. The water stop plate 5131 is connected to the base 14 through the first connection hole 1492 and the second connection hole 5131B. For example, using a screw member, after passing through the first connection hole 1492 and the second connection hole 5131B from bottom to top respectively, the water stop plate 5131 may be fixedly connected onto the base 14.

[0043] As shown in FIG. 12, on the bottom surface of the base 14, there is further a drain hole 142. The drain hole 142 is provided between the two mounting post main bodies 1493, and the drain hole 142 is used to discharge the water accumulation in the housing. For example, the drain hole 142 may communicate with the cavity where the outdoor fan 204 of the outdoor unit 20 is located. The water droplets on the water stop plate 5131 flow downward and are discharged downward through the drain hole 142 into the cavity where the outdoor fan 204 of the outdoor unit 20 is located from the fresh air device 100.

[0044] In some embodiments, as shown in FIGS. 9 and 12, the base 14 further has a water collecting groove 148. The water collecting groove 148 is provided on the bottom surface of the accommodating groove 141 of the base 14, and the drain hole 142 is provided in the water collecting groove 148. The water collecting groove 148 serves to collect water and can discharge the residual water in the air passage cavity 513 downward.

[0045] As shown in FIGS. 13 and 15, in some embodiments, the ventilation bracket 5 further includes a second locking groove 54 and a connecting protrusion 55. The second locking groove 54 and the connecting protrusion 55 are provided at the blowing end 512 of the ventilation bracket 5. The second locking groove 54 is located at the rear side of the blowing end 512, and the connecting protrusion 55 is located at the middle position of the blowing end 512. The second locking groove 54 is positioned by fitting and engaging with the base 14. The connecting protrusion 55 and the base 14 may be tightened and connected by screws. The ventilation bracket 5 and the base 14 are removably connected by engagement, screws, etc., and are easy to process, remove, and clean.

[0046] As shown in FIG. 9, the housing 1 further includes a water stop portion 147.
