Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, in particular to a wall-mounted air conditioner. BACKGROUND

[0002] The wall-mounted air conditioner comprises an air conditioner indoor unit. The casing of the air conditioner indoor unit comprises at least an air conditioner air inlet and an air conditioner air outlet which are in communication with the indoor environment. Inside the casing, a heat exchange fan, a fresh air volute and an indoor heat exchanger are arranged. The heat exchange fan is used to introduce indoor air into the casing through the air conditioner air inlet, and the indoor air is exchanged by the indoor heat exchanger and then flows to the indoor environment through the air conditioner air outlet. The fresh air volute is provided with a fresh air fan. The fresh air volute comprises at least a fresh air inlet and an indoor outlet. The fresh air fan rotates to introduce outdoor fresh air into the fresh air volute through the fresh air inlet, and the outdoor fresh air flows to the indoor environment through the indoor outlet, thereby realizing the fresh air function.

[0003] The fresh air volute can further comprise a purification air inlet. The fresh air volute is provided with a filter assembly. The fresh air fan rotates to introduce indoor air into the fresh air volute through the purification air inlet. After being filtered and purified by the filter assembly, the indoor air flows to the indoor environment, thereby realizing the indoor air circulation and purification function.

[0004] In the related art, if the fresh air and purification functions are simultaneously provided, a separate valve or baffle is required for each air inlet and outlet. Correspondingly, a separate driving element is required to drive the movement of the valve or baffle. As a result, a large number of driving elements are required for the fresh air module to correspond to the valve or baffle, so as to independently control the opening and closing of the fresh air and purification functions. The driving elements generally have a large size, occupy a large space, and have a high cost. Therefore, the overall size of the fresh air module is large, and the cost is high. At the same time, the reliability of the driving elements is low, and faults are prone to occur during use. Too many driving elements increase the failure rate of the fresh air module, and the operation reliability of the fresh air module is low.

[0005] In addition, in the related art, there is a technical solution for controlling a valve or baffle by using one driving element to realize the mutual exclusion of the fresh air and purification functions. This technical solution reduces the cost to a certain extent, but cannot realize the simultaneous opening or closing of the fresh air and purification functions, and the user experience is poor. SUMMARY

[0006] The present application aims to at least partially solve one of the technical problems in the related art. To this end,

[0007] The present application provides a wall-mounted air conditioner, comprising:

[0008] a casing, an inner portion of the casing being provided with a first inner cavity and a second inner cavity along a length direction; the casing is provided with an air conditioner air inlet and an air conditioner air outlet at a top portion and a front bottom portion, respectively;

[0009] an indoor heat exchanger arranged in the first inner cavity, the indoor heat exchanger being used to exchange heat of air in the casing;

[0010] A heat exchange fan is arranged in the first inner cavity and below the indoor heat exchanger.

[0011] A fresh air volute is arranged in the second inner cavity, and a fresh air duct is formed in the fresh air volute. A fresh air inlet, an indoor outlet, and a purification inlet are arranged on the fresh air volute and communicate with the fresh air duct.

[0012] A fresh air fan is arranged in the fresh air duct.

[0013] A filter assembly is arranged in the fresh air duct.

[0014] A baffle assembly includes a first baffle and a second baffle movably arranged on the fresh air volute.

[0015] A first driving device is connected to the baffle assembly and used to drive the first baffle and the second baffle to move.

[0016] When the baffle assembly is in a first position, the first baffle blocks the communication between the fresh air inlet and the fresh air duct, and the second baffle blocks the communication between the purification inlet and the fresh air duct.

[0017] When the baffle assembly is in a second position, outdoor fresh air enters the fresh air duct through the fresh air inlet, indoor air enters the fresh air duct through the purification inlet, and the outdoor fresh air and the indoor air are mixed and output to the indoor through the indoor outlet by the operation of the fresh air fan.

[0018] The hanging air conditioner provided by the technical solution has a purification function and a fresh air function, and has a working mode of simultaneously opening and closing the purification function and the fresh air function, which is simple and convenient. The first driving device controls the movement of the first baffle and the second baffle, so that the baffle assembly moves between different positions, thereby solving the problem that the existing technology can only realize independent control of the fresh air function or the purification function by using one baffle controlled by one first driving device, and cannot realize simultaneous opening and closing of the fresh air function and the purification function.

[0019] The application further provides a hanging air conditioner, which includes:

[0020] A shell has a first inner cavity and a second inner cavity arranged in the length direction inside the shell. An air conditioner inlet and an air conditioner outlet are arranged on the top and the front bottom of the shell, respectively.

[0027] A first driving device is connected with the baffle assembly to drive the first baffle and the second baffle to move towards each other or away from each other.

[0028] When the baffle assembly is in a first position, the first baffle blocks the communication between the new air inlet and the new air duct, and the second baffle blocks the communication between the purification inlet and the new air duct.

[0029] When the baffle assembly is in a second position, outdoor new air enters the new air duct through the new air inlet by operating the new air fan, indoor air enters the new air duct through the purification inlet, and the outdoor new air and the indoor air are mixed and output to the indoor through the indoor air outlet.

[0030] When the baffle assembly is in a third position, the second baffle blocks the communication between the new air inlet and the new air duct, and indoor air enters the new air duct through the purification inlet and is output to the indoor through the indoor air outlet by operating the new air fan.

[0031] When the baffle assembly is in a fourth position, the first baffle blocks the communication between the purification inlet and the new air duct, and outdoor new air enters the new air duct through the new air inlet and is output to the indoor through the indoor air outlet by operating the new air fan.

[0032] The hanging air conditioner provided by the technical scheme can control the first baffle and the second baffle to move towards each other or away from each other by a first driving device, so that the baffle assembly moves between different positions, and the hanging air conditioner has four working modes, i.e., a single new air opening function, a single purification function, simultaneous opening of the purification function and the new air function, and simultaneous closing of the purification function and the new air function, which is simple and convenient.

[0034] In some embodiments, a partition is arranged between the first sliding part and the second sliding part, the partition is formed with a first channel and a second channel, the first channel is arranged corresponding to the fresh air inlet to connect the fresh air inlet and the fresh air duct, and the second channel is arranged corresponding to the purified air inlet to connect the purified air inlet and the fresh air duct.

[0035] In some embodiments, the first baffle is formed with a first opening, when the baffle assembly is in the second position, the fresh air inlet and the first channel are connected through the first opening.

[0036] In some embodiments, the first side wall extends along a thickness direction of the shell, the purified air inlet is arranged close to a front end of the first side wall relative to the fresh air inlet, and the first opening is arranged close to a rear end of the first baffle.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0089] The hanging air conditioner provided by the embodiment of the present application can have various implementation forms.

[0090] Among them, Figures 1-23 is an illustrative embodiment of the hanging air conditioner of the present application. The hanging air conditioner includes an air conditioner indoor unit, which is arranged in the indoor environment for heat exchange with the indoor environment. The hanging air conditioner can include an air conditioner outdoor unit, which is usually arranged in the outdoor environment for taking the heat of the indoor environment to the outdoor environment.

[0091] With reference to Figures 1-3 In this embodiment, the air conditioner indoor unit includes a shell 1. The shell 1 is installed in the indoor environment, and the shell 1 forms the overall appearance of the air conditioner indoor unit.

[0092] With reference to Figure 1 The shell 1 is generally arranged in the shape of a rectangular parallelepiped. The shell 1 has a top end and a bottom end, and the top end and the bottom end of the shell 1 are two ends arranged opposite to each other in the height direction of the shell 1. The left side of the shell 1 and the right side of the shell 1 are two sides arranged opposite to each other in the length direction of the shell 1, and the front side of the shell 1 and the back side of the shell 1 are two sides arranged opposite to each other in the thickness direction of the shell 1.

[0093] Among them, the shell 1 is arranged at the top of the indoor environment or the upper space of the indoor environment, the front side of the shell 1 is arranged towards the user, and the back side of the shell 1 is arranged towards the wall and is suitable for being connected with the wall.

[0094] It should be noted that the directions described in the present application are based on the direction that the user faces the air conditioner indoor unit, wherein the side of the air conditioner indoor unit facing the user during use is defined as the front side, and the opposite side is defined as the back side, and the left side and the right side are distinguished from each other in the direction that the user faces the air conditioner indoor unit.

[0095] A heat exchange air duct is formed inside the shell 1. The heat exchange air duct is used to accommodate and fix various components in the air conditioner indoor unit 100, so that collision between external objects and various components in the shell 1 can be avoided, thereby improving the reliability of the air conditioner indoor unit 100 during transportation or installation.

[0096] In some embodiments of the present application, referring to Figure 2 , the shell 1 can include an air conditioner air inlet 13.

[0097] The air conditioner air inlet 13 communicates with the heat exchange air duct. The air conditioner air inlet 13 serves as an entrance for air flow from outside the shell 1, allowing indoor air to enter the heat exchange air duct from the air conditioner air inlet 13.

[0098] In some embodiments of the present application, referring to Figure 2 , the shell 1 can include an air conditioner air outlet 14.

[0099] The air conditioner air outlet 14 communicates with the heat exchange air duct. The air conditioner air outlet 14 serves as an exit for air flow from the heat exchange air duct, allowing air flow in the heat exchange air duct to flow out from the air conditioner air outlet 14.

[0100] In some embodiments of the present application, referring to , the air conditioner air inlet 13 can be formed on the top of the shell 1. The air conditioner air outlet 14 can be formed on the front side of the shell 1 and arranged close to the bottom of the shell 1, i.e., the air conditioner air outlet 14 is located at the front bottom of the shell 1. In this embodiment, when the air conditioner indoor unit is working, the air conditioner indoor unit 100 takes in air from the top and discharges air to the front, which is convenient for arrangement.

[0101] The air conditioner air outlet 14 can be in the shape of a long strip, and the air conditioner air outlet 14 can be arranged along the length direction of the shell 1, thereby improving the appearance of the air conditioner indoor unit 100.

[0102] Figure 2 In some embodiments of the present application, referring to , the air conditioner indoor unit 100 can include an air deflector 15.

[0103] The air deflector 15 is rotatably connected to the shell 1 and arranged at the air conditioner air outlet 14. The air deflector 15 opens or closes the air conditioner air outlet 14, and when the air deflector 15 opens the air conditioner air outlet 14, the air deflector 15 is used to guide the heat exchange air flow.

[0104] In some embodiments of the present application, referring to

[0105] , the air conditioner indoor unit 100 can include an air inlet grille 16.

[0106] The air inlet grille 16 is arranged at the air conditioner air inlet 13 and used to filter air to prevent large impurities from entering the heat exchange air duct. Figure 4The air conditioner indoor unit 100 can include an indoor heat exchanger 2. The indoor heat exchanger 2 extends along the length direction of the shell 1, and is arranged in the heat exchange air duct for heat exchange with the air flow in the shell 1.

[0107] In some embodiments of the present application, the air conditioner indoor unit 100 can include a heat exchange fan 3.

[0108] The heat exchange fan 3 is arranged in the heat exchange air duct, and the axial direction of the heat exchange fan 3 extends along the length direction of the shell 1, for driving the indoor air outside the shell 1 to enter the heat exchange air duct in the shell 1 through the air inlet, and driving the air in the heat exchange air duct to flow along the air conditioner air inlet 13 towards the air conditioner air outlet 14.

[0109] With reference to Figure 4 , the heat exchange fan 3 is arranged below the indoor heat exchanger 2. The indoor heat exchanger 2 can be located on the inner side of the air conditioner air inlet 13. The heat exchange fan 3 can be located on the side of the indoor heat exchanger 2 away from the air conditioner air inlet 13. That is, in the direction of the air flow in the shell 1, the heat exchange fan 3 is located downstream of the indoor heat exchanger 2.

[0110] In some embodiments of the present application, the heat exchange fan 3 is a cross-flow fan.

[0111] When the air conditioner indoor unit 100 is running, under the driving of the heat exchange fan 3, the indoor air enters the heat exchange air duct through the air conditioner air inlet 13, the indoor air in the heat exchange air duct flows through the indoor heat exchanger 2 for heat exchange, and the heat exchanged air flows out of the air conditioner air outlet 14 to the indoor, so as to make the air conditioner refrigerate and heat, and play a role in adjusting the indoor temperature to achieve the user's comfortable temperature.

[0112] With reference to Figure 6 , in some embodiments of the present application, the shell 1 can include a base 11. The base 11 forms the rear side of the air conditioner indoor unit 100, and the base 11 is adapted to be hung on the wall.

[0113] With reference to Figure 5 , the shell 1 can include a cover 12. The cover 12 is arranged on the base 11, and the cover 12 and the base 11 form the heat exchange air duct.

[0114] In some embodiments of the present application, the cover 12 is substantially in the shape of a rectangular frame. The rear side of the cover 12 is open, and the cover 12 is arranged on the front side of the base 11 and connected with the base 11 to form the shell 1.

[0115] With reference to Figure 5 , the air conditioner air inlet 13 and the air conditioner air outlet 14 are both arranged on the cover 12. The indoor heat exchanger 2 and the heat exchange fan are both mounted on the base 11.

[0116] In some embodiments of the present application, the outer cover 12 can be provided integrally. Of course, in other embodiments, the outer cover 12 can be provided separately.

[0117] The outdoor unit of the air conditioner can include an outdoor housing. An outdoor heat exchange air duct can be provided in the outdoor housing.

[0118] An outdoor air inlet can be provided on the outdoor housing. The outdoor air inlet can be in communication with the outdoor heat exchange air duct. The outdoor air inlet can be used to introduce outdoor air into the outdoor heat exchange air duct.

[0119] An outdoor air outlet can be provided on the outdoor housing. The outdoor air outlet can be in communication with the outdoor heat exchange air duct. The outdoor air outlet can be used to introduce outdoor air into the outdoor heat exchange air duct.

[0120] The outdoor unit of the air conditioner can include an outdoor heat exchanger. The outdoor heat exchanger can be provided in the outdoor heat exchange air duct.

[0121] The outdoor unit of the air conditioner can include an outdoor fan. The outdoor fan can be provided in the outdoor heat exchange air duct.

[0122] Rotation of the outdoor fan causes outdoor air to enter the heat exchange air duct from the outdoor air inlet and exchange heat with the outdoor heat exchanger. The outdoor air after heat exchange flows out of the outdoor heat exchange air duct from the outdoor air outlet.

[0123] The air conditioner can include a compressor. The compressor is provided in the outdoor heat exchange air duct.

[0124] The air conditioner can include a throttling device. The throttling device is used for throttling. The throttling device can be provided in the indoor unit or the outdoor unit of the air conditioner.

[0125] The air conditioner performs a refrigeration cycle of the air conditioner by using the compressor, the condenser, the throttling device and the evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to air that has been adjusted and heat exchanged.

[0126] The compressor compresses the refrigerant gas in a low temperature and low pressure state to discharge refrigerant gas in a high temperature and high pressure state. The discharged refrigerant gas flows into the condenser.

[0127] The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0128] The throttling device expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser to a low-pressure liquid-phase refrigerant.

[0129] The evaporator evaporates the refrigerant expanded in the throttling device, and returns the refrigerant gas in a low temperature and low pressure state to the compressor.

[0130] The evaporator can achieve a refrigeration effect by exchanging heat with the material to be cooled using the latent heat of evaporation of the refrigerant. Throughout the cycle, the air conditioner can adjust the temperature of the indoor space.

[0131] In both the indoor heat exchanger and the outdoor heat exchanger, one of which is a condenser and the other of which is an evaporator, when the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.

[0132] Reference Figure 6 The housing 1 is internally provided with a first partition 111. The first partition 111 is located at one end in the axial direction of the heat exchange fan 3.

[0133] The housing 1 is internally provided with a second partition 112. The first partition 111 and the second partition 112 are correspondingly arranged along the length direction of the housing 1, and together define a first inner cavity 18 for mounting the heat exchange fan 3.

[0134] The heat exchange fan 3 can also be axially limited by the first partition 111 and the second partition 112, preventing the heat exchange fan 3 from moving along the length direction of the housing 1, thereby increasing the reliability of the heat exchange fan 3 installation.

[0135] In some embodiments of the present application, a second inner cavity 19 is formed in the housing 1. The second inner cavity 19 and the first inner cavity 18 are separated from each other by the first partition 111, so that the first inner cavity 18 and the second inner cavity 19 are arranged along the length direction.

[0140] In some embodiments of the present application, the air conditioner indoor unit 100 can include a fresh air inlet pipe. One end of the fresh air inlet pipe is connected to the fresh air inlet 41, and the other end extends to the outdoor environment.

[0141] The shell 1 can comprise an air conditioner fresh air outlet 17. The air conditioner fresh air outlet 17 is in communication with an indoor air outlet 42, so that outdoor fresh air in a fresh air duct 44 flows to the indoor air through the air conditioner fresh air outlet 17.

[0142] The fresh air module can comprise the indoor air outlet 42. The indoor air outlet 42 is formed on the fresh air volute 4 and is adapted to be in communication with the indoor environment. Through the operation of the fresh air fan 5, outdoor fresh air is introduced into the fresh air duct 44 through the fresh air inlet 41, passes through the indoor air outlet 42, and flows to the indoor air through the air conditioner fresh air outlet 17.

[0143] Reference Figure 8 The fresh air module can comprise a purification air inlet 40. The purification air inlet 40 is formed on the fresh air volute 4 and is adapted to be in communication with the indoor environment.

[0144] The fresh air inlet 41, the indoor air outlet 42, and the purification air inlet 40 are all in communication with the fresh air duct 44. Through the operation of the fresh air fan 5, outdoor fresh air and indoor air can be mixed in the fresh air duct 44 and then discharged to the indoor air through the indoor air outlet 42.

[0145] In some embodiments of the present application, the fresh air volute 4 is connected to the base. The fresh air volute 4 is connected to the base by fasteners such as screws or bolts. In order to prevent the vibration generated by the rotation of the fresh air fan 5 from being transmitted to the shell 1 and other components, a damping rubber is provided between the fastener and the base to buffer and absorb the vibration.

[0146] In some embodiments of the present application, with reference to Figure 10 The fresh air module can comprise a filter assembly 43. The filter assembly 43 is inserted into the fresh air duct 44.

[0147] The outdoor fresh air and / or indoor air entering the fresh air volute 4 is filtered and purified by the filter assembly 43 and then enters the indoor air through the indoor air outlet 42.

[0148] With reference to Figure 11 The fresh air duct 44 can comprise an air inlet cavity 441. The fresh air inlet 41 and the purification air inlet 40 are in communication with the air inlet cavity 441.

[0149] The fresh air duct 44 can comprise a fan cavity 442. The indoor air outlet 42 is in communication with the fan cavity 442, and the fan cavity 442 is in communication with the air inlet cavity 441 through an air suction port.

[0150] The fresh air fan 5 is arranged in the fan cavity 442. The filter assembly 43 is inserted into the air inlet cavity 441 to cover the air suction port, so as to filter and purify the airflow flowing into the fan cavity 442.

[0151] With reference to Figure 12 The filter assembly 43 can comprise a filter frame 431. The filter frame 431 is arranged on the fresh air volute 4 in a pullable manner.

[0152] The filtering assembly 43 can comprise a filtering screen 432. The filtering screen 432 is arranged on the filtering frame 431, and is configured to filter and purify the outdoor fresh air and the indoor air, so as to prevent impurities and flocculation in the outdoor fresh air from entering the indoor environment, and to purify the indoor air in an internal circulation manner, thereby improving the air quality of the indoor environment.

[0153] With reference to Figure 12 , the fresh air volute 4 can comprise a second volute 48. The second volute 48 is provided with an air inlet.

[0154] The fresh air volute 4 can comprise a first volute 47. The first volute 47 is tightly connected to one side of the second volute 48, and cooperates with the second volute 48 to define an air inlet cavity 441. The first volute 47 comprises a first side wall.

[0155] The fresh air volute 4 can comprise a third volute 49. The third volute 49 is tightly connected to the other side of the second volute 48, and cooperates with the second volute 48 to define a fan cavity 442.

[0156] In the embodiment, the first volute 47, the second volute 48 and the third volute 49 can be connected by fasteners and / or buckles, so as to reliably protect the fresh air fan and facilitate disassembly and assembly.

[0157] The fresh air module can comprise a baffle assembly. The baffle assembly is arranged on the fresh air volute 4, and is configured to open or close the fresh air function and / or the purification (indoor air internal circulation purification) function.

[0158] In some embodiments of the present application, with reference to Figure 10 , Figure 12 The baffle assembly can comprise a first baffle 6. The first baffle 6 is movably arranged on the fresh air volute 4. The first baffle 6 can move along the thickness direction of the housing 1.

[0159] In some embodiments of the present application, the baffle assembly can comprise a second baffle 7. The second baffle 7 is movably arranged on the fresh air volute 4. The second baffle 7 can move along the thickness direction of the housing 1.

[0160] In some embodiments of the present application, the fresh air module can comprise a first driving device 9. The first driving device 9 is connected to the baffle assembly, and is configured to drive the baffle assembly to move between different positions.

[0161] The first driving device 9 is connected to the first baffle 6 and the second baffle 7, and is configured to drive the first baffle 6 and the second baffle 7 to move.

[0162] In the embodiment, the first driving device 9 can drive the baffle assembly to switch between a first position and a second position.

[0163] refer to Figure 15 When the baffle assembly is in the first position, the first baffle 6 isolates the connection between the fresh air inlet 41 and the fresh air duct 44, and the second baffle 7 isolates the connection between the purification air inlet 40 and the fresh air duct 44.

[0164] In other words, when the baffle assembly is in the first position, the fresh air inlet 41 and the fresh air duct 44 are separated by the first baffle 6, so that the two are not connected; the purification air inlet 40 and the fresh air duct 44 are separated by the second baffle 7, so that the two are also connected; thus, the fresh air module is in the first state where the fresh air inlet and the purification air inlet are both closed. In this state, the fresh air function and the purification function of the wall-mounted air conditioner are both closed.

[0165] refer to Figure 16 When the baffle assembly is in the second position, the fresh air fan 5 operates, and the outdoor fresh air enters the fresh air duct 44 through the fresh air inlet 41. The indoor airflow enters the fresh air duct 44 through the purification inlet 40. After the outdoor fresh air and the indoor airflow are mixed, they are filtered by the filter assembly 43 and finally output to the room through the indoor air outlet 42.

[0166] in, Figure 16 The dashed lines depicted are used to represent the flow path of outdoor fresh air, and the arrows on the dashed lines are used to represent the flow direction of outdoor fresh air. Figure 16 The solid lines depicted are used to represent the airflow path in the room, and the arrows on the solid lines are used to represent the airflow direction in the room.

[0167] In other words, when the baffle assembly is in the second position, the first baffle 6 and the second baffle 7 will not separate the fresh air inlet 41 from the fresh air duct 44, or the purification air inlet 40 from the fresh air duct 44, so that the fresh air module is in the second state where the fresh air inlet and the purification air inlet are opened at the same time. In this state, the fresh air function and the purification function of the wall-mounted air conditioner are turned on at the same time.

[0168] The wall-mounted air conditioner provided in this embodiment uses a first driving device 9 to control the movement of a first baffle 6 and a second baffle 7, allowing the baffle assembly to move between different positions. When the baffle assembly is in the first position, the wall-mounted air conditioner is in a state where both the purification and fresh air functions are simultaneously off; when the baffle assembly is in the first position, the wall-mounted air conditioner is in a state where both the purification and fresh air functions are simultaneously on. The structure is simple and the operation is convenient. It effectively solves the defect in the prior art where controlling the baffle with a single first driving device 9 can only achieve independent control of either the fresh air or purification function, and cannot achieve simultaneous on / off operation of both functions.

[0169] In some embodiments of this application, the first driving device 9 can drive the baffle assembly to switch between a first position, a second position, a third position, and a fourth position.

[0170] Referring to Figure 17 , when the baffle assembly is in the third position, the second baffle 7 separates the fresh air inlet 41 from the fresh air duct 44. By operating the fresh air fan 5, indoor air flows from the purification air inlet 40 into the fresh air duct 44, is filtered by the filter assembly 43, and is output to the indoor space through the indoor air outlet 42.

[0171] That is, when the baffle assembly is in the third position, the fresh air inlet 41 is separated from the fresh air duct 44 by the second baffle 7, and the purification air inlet 40 is still connected to the fresh air duct 44, so that the fresh air module is in a third state in which the fresh air inlet is closed and the purification air inlet is open. In this state, the ceiling-mounted air conditioner only opens the purification function. Figure 17 The solid line in the figure represents the flow path of indoor air, and the arrow on the solid line represents the flow direction of indoor air.

[0172] Referring to Figure 18 , when the baffle assembly is in the fourth position, the first baffle 6 separates the purification air inlet 40 from the fresh air duct 44. By operating the fresh air fan 5, outdoor fresh air enters the fresh air duct 44 through the fresh air inlet 41 and is output to the indoor space through the indoor air outlet 42. In this state, the ceiling-mounted air conditioner only opens the fresh air function. Figure 18 The dashed line in the figure represents the flow path of indoor air, and the arrow on the dashed line represents the flow direction of indoor air.

[0173] That is, when the baffle assembly is in the fourth position, the purification air inlet 40 is separated from the fresh air duct 44 by the first baffle 6, and the fresh air inlet 41 is still connected to the fresh air duct 44, so that the fresh air module is in a third state in which the purification air inlet is closed and the fresh air inlet is open. In this state, the ceiling-mounted air conditioner only opens the fresh air function.

[0174] In this embodiment, when the baffle assembly moves from the first position to the second position, the first baffle 6 and the second baffle 7 move towards each other, and vice versa. When the baffle assembly moves from the third position to the fourth position, the first baffle 6 and the second baffle 7 move away from each other, and vice versa.

[0175] The ceiling-mounted air conditioner provided in this embodiment has a first driving device 9 to control the movement of the first baffle 6 and the second baffle 7, so that the first position, the second position, the third position, and the fourth position can be switched, and the ceiling-mounted air conditioner has four working modes, i.e., a single fresh air function, a single purification function, simultaneous opening of the purification function and the fresh air function, and simultaneous closing of the purification function and the fresh air function, which is simple and convenient.

[0176] In this embodiment, the ceiling-mounted air conditioner can simultaneously have the fresh air function and the purification function, and users can select different working modes according to their needs, thereby improving user experience.

[0177] In some embodiments of the present application, referring to Figure 19 , the fresh air volute 4 can include a first side wall 471.

[0178] In the present embodiment, referring to Figure 13 , the first side wall 471 is arranged to extend along the thickness direction of the housing 1, i.e., the length direction of the first side wall 471 is the thickness direction of the housing 1.

[0179] Referring to Figure 19 , the fresh air inlet 41 and the purification air inlet 40 are arranged on the first side wall 471, and the fresh air inlet 41 and the purification air inlet 40 are arranged along the length direction of the first side wall 471.

[0180] In some embodiments of the present application, referring to Figure 20 , the fresh air volute 4 is provided with a first sliding part 45. The first sliding part 45 is for the first baffle 6 to slide.

[0181] In some embodiments of the present application, the fresh air volute 4 is provided with a second sliding part 46. The second sliding part 46 is for the second baffle 7 to slide.

[0182] Referring to Figure 20 , the first sliding part 45 and the second sliding part 46 are arranged opposite to each other. By arranging the first sliding part 45 and the second sliding part 46, the first baffle 6 and the second baffle 7 are arranged to slide along the extension direction of the first sliding part 45 and the second sliding part 46 respectively, thereby improving the movement stability of the first baffle 6 and the second baffle 7.

[0183] In some embodiments of the present application, a separation part 8 is arranged between the first sliding part 45 and the second sliding part 46.

[0184] In the present embodiment, the first side wall 471 and the separation part 8 are arranged to be spaced apart, so that the first sliding part 45 for the first baffle 6 to slide is formed between the first side wall 471 and the separation part 8. A limiting part is arranged in the fresh air volute, and the limiting part and the separation part 8 are arranged to be spaced apart, so that the second sliding part 46 for the second baffle 7 to slide is formed between the limiting part and the separation part 8.

[0185] Of course, in other embodiments, the first sliding part 45 and the second sliding part 46 can be separately arranged as slide structures.

[0186] In some embodiments of the present application, referring to Figure 20 , a first passage 4431 is arranged on the separation part 8. The first passage 4431 is arranged corresponding to the fresh air inlet 41, and the first passage 4431 communicates the fresh air inlet 41 and the fresh air duct 44.

[0187] In some embodiments of the present application, the isolation portion 8 is provided with a second passage 4432. The second passage 4432 is arranged corresponding to the purification air inlet 40, and the second passage 4432 communicates the purification air inlet 40 and the fresh air duct 44.

[0188] With reference to Figure 21 , the first baffle 6 is provided with a first passage 61.

[0189] With reference to Figure 16 , when the baffle assembly is in the second position, the fresh air inlet 41, the first passage 61 and the first passage 4431 are sequentially communicated corresponding to each other, so that the fresh air inlet 41 is communicated with the fresh air duct 44, and the fresh air function is opened. In this position, the first baffle 6 and the second baffle 7 do not separate the purification air inlet 40 and the fresh air duct 44.

[0190] With reference to Figure 16 , when the baffle assembly is in the second position, the second baffle 7 is between the purification air inlet 40 and the fresh air inlet 41, and does not interfere with the fresh air inlet and the purification air inlet of the fresh air duct 44, and the purification function is opened.

[0191] In some embodiments of the present application, the first side wall 471 extends along the thickness direction of the shell 1.

[0192] It can be understood that the first sliding portion 45 and the second sliding portion 46 extend along the thickness direction of the shell 1. The first baffle 6 and the second baffle 7 move along the thickness direction of the shell 1.

[0193] With reference to Figure 15 , the two ends of the first side wall 471 in the length direction are respectively the front end and the rear end. The purification air inlet 40 is arranged close to the front end of the first side wall 471 relative to the fresh air inlet 41, and the first passage 61 is arranged close to the rear end of the first baffle 6.

[0194] When the baffle assembly is in the first position, the first baffle 6 moves to the rear end of the first sliding portion 45, so that the fresh air inlet 41 is separated from the first passage 4431, and the fresh air function is closed; the second baffle 7 moves to the front end of the second sliding portion 46, so that the second passage 4432 is separated from the fresh air duct 44, and the purification function is closed.

[0195] In some embodiments of the present application, the second baffle 7 is provided with a second passage 71. The second passage 71 is arranged in the middle of the first baffle 6.

[0196] When the baffle assembly is in the fourth position, the fresh air inlet 41 and the first passage 4431 are communicated through the second passage 71. With reference to Figure 18When the baffle assembly is in the fourth position, the fresh air inlet 41, the first passage 4431 and the second through hole 71 correspond to and communicate with each other in sequence, so that the fresh air inlet 41 communicates with the fresh air duct 44.

[0197] Specifically, when the baffle assembly is in the fourth position, the first baffle 6 moves to the front end of the first sliding part 45, so that the purification air inlet 40 is cut off from the second passage 4432, and the purification function is closed; the second baffle 7 moves to the rear end of the second sliding part 46, at this time, the fresh air inlet 41 communicates with the first passage 4431 through the second through hole 71, and the fresh air function is opened.

[0198] Reference Figure 17 When the baffle assembly is in the third position, the rear part of the second baffle 7 cuts off the communication between the first passage 4431 and the fresh air duct 44, so as to cut off the communication between the fresh air inlet 41 and the fresh air duct 44, and the fresh air function is closed; the first baffle 6 is located between the purification air inlet 40 and the fresh air inlet 41, and does not interfere with the fresh air inlet and the purification air inlet of the fresh air duct 44, and cooperates with the second baffle 7 to open the purification function.

[0199] In some embodiments of the present application, the ratio between the air inlet area of the fresh air inlet 41 and the air inlet area of the purification air inlet 40 ranges from 1 to 2. By setting the ratio between the air inlet area of the fresh air inlet 41 and the air inlet area of the purification air inlet 40 within a reasonable range, when the fresh air function and the purification function are opened, the fresh air inlet amount and the purification air inlet amount are roughly equivalent.

[0200] In some embodiments of the present application, with reference to Figure 21 , Figure 22 The first driving device 9 can include a first driving motor 91. The first driving motor 91 is installed on the fresh air volute 4, and the first driving motor 91 is located outside the fresh air duct 44.

[0201] The first driving motor 91 has a driving shaft 911.

[0202] The first driving device 9 can include a first gear 92. The first gear 92 is sleeved on the driving shaft 911 of the first driving motor 91, and the driving shaft 911 rotates to drive the first gear 92 to rotate.

[0203] The first driving device 9 can include a first rack 93. The first rack 93 is arranged on the side surface of the first baffle 6, and the first rack 93 is engaged with the first gear 92, and the first gear 92 rotates to drive the first rack 93 to move.

[0204] The first driving device 9 can include a second rack 94. The second rack 94 is arranged on the side of the second baffle 7 facing the first baffle 6, and the second rack 94 is engaged with the first gear 92, and the first gear 92 rotates to drive the second rack 94 to move.

[0205] The first gear 92 is engaged between the first rack 93 and the second first gear 92, and the first gear 92 rotates to drive the first baffle 6 and the second baffle 7 to move in opposite directions. Through the cooperation of the first driving motor 91, the first gear 92 and the rack, the movement of the first baffle 6 and the second baffle 7 can be realized, the number of the first driving motor 91 is reduced, and the cost is reduced.

[0206] It can be understood that the first rack 93 and the second rack 94 are straight racks.

[0207] In the embodiment, the isolation part 8 is provided with a containing space, and the first gear 92 is arranged in the containing space. The fresh air volute 4 is provided with an opening communicating with the containing space, and the driving shaft 911 of the first driving motor 91 penetrates the opening and is connected with the first gear 92.

[0208] In some embodiments of the present application, with reference to Figure 19 , the size of the fresh air inlet 41 in the thickness direction of the shell 1 is L, and L is not less than 15 mm, that is, L≥15 mm.

[0209] The size L cannot be too small, otherwise the fresh air inlet 41 is not conducive to air inlet, which leads to too small fresh air volume and poor fresh air function effect. In order to increase the fresh air inlet volume, the size L of the fresh air inlet 41 in the thickness direction of the shell 1 is set to be not less than a first parameter value. For example, the first numerical parameter can be 15 mm, 15.5 mm, or 16 mm. A suitable specific parameter is selected in specific design.

[0210] In some embodiments of the present application, the size of the fresh air inlet 41 in the thickness direction of the shell 1 is L, and L is not more than 40 mm, that is, L≤40 mm.

[0211] The size L cannot be too large, otherwise the thickness size of the fresh air module is too large, which leads to the thickness size of the air conditioner indoor unit 100 of the ceiling-mounted air conditioner being too large, and the overall size is increased. In order to reduce the overall size, the size L is set to be not more than a second parameter value. For example, the second numerical parameter can be 40 mm, 39 mm, or 38 mm. A suitable specific parameter is selected in specific design.

[0212] In some embodiments of the present application, the size of the fresh air inlet 41 in the thickness direction of the shell 1 is L, wherein 15 mm≤L≤40 mm.

[0213] In the embodiment, the size L of the fresh air inlet 41 is set to any value between 15mm and 40mm, which ensures sufficient fresh air inlet volume while reducing the size of the whole machine, and facilitates the processing of the fresh air inlet 41.

[0214] In some embodiments of the present application, the size of the fresh air inlet 41 in the thickness direction of the shell 1 is L, and the thickness size of the first side wall 471 of the fresh air volute 4 in the thickness direction of the shell 1 is M. Wherein, M is greater than or equal to 6L.

[0215] With reference to Figure 19 In the embodiment, the thickness size M of the first side wall 471 in the thickness direction of the shell 1 is substantially 6L. The fresh air inlet 41 is located at a position of 2L of the first side wall 471, and the purification air inlet 40 is located at a position of 6L of the first side wall 471, with the rear end of the first side wall 471 as the starting point.

[0216] The length size of the first baffle 6 and the second baffle 7 is not less than 3L. In the embodiment, the length size of the first baffle 6 and the second baffle 7 is substantially 3L. Wherein, the first opening 61 is located at a position of 1L of the first baffle 6, and the second opening 71 is located at a position of 2L of the second baffle 7, with the rear end of the baffle as the starting point.

[0217] The hanging air conditioner provided in the embodiment can maximize the utilization of the thickness size of the whole machine, and the fresh air inlet 41 and the purification air inlet 40 can obtain the maximum air inlet area under the condition of thickness size limitation.

[0218] In some embodiments of the present application, with reference to Figure 23 The air conditioner indoor unit 100 can include a third driving motor 113. Wherein, the third driving motor 113 is installed on the base 11.

[0219] The third driving motor 113 is connected to the heat exchange fan 3 at the end away from the fresh air volute 5, to drive the heat exchange fan 3 to rotate.

[0220] Wherein, the other end of the heat exchange fan 3 is connected to the fresh air fan 5 through the connecting shaft 31, and the heat exchange fan 3 drives the fresh air fan 5 to rotate.

[0221] In the embodiment, the single third driving motor 113 drives the fresh air fan 5 and the heat exchange fan 3 to rotate at the same time, which can reduce the use of fresh air motor, save the cost of motor, make the fresh air module miniaturization, and further reduce the length direction of the whole machine, the structure layout and design are more reasonable, the space utilization is higher, and the cost of plastic material is saved.

[0222] It can be understood that when the fresh air fan 5 and the heat exchange fan 3 are driven by the third driving motor 113, if the user does not want to introduce fresh air into the room and only wants to drive the heat exchange fan 3 to heat the indoor air, the baffle assembly is slid to the third position to close the fresh air inlet, so as to avoid introducing fresh air into the room.

[0223] At this time, the heat exchange fan 3 is opened to rotate and drive the fresh air fan 5 to rotate synchronously. Since the fresh air inlet 41 is closed, the rotation of the fresh air fan 5 drives the indoor air to enter the fresh air volute through the purification air inlet 40. The indoor air entering the fresh air volute 4 is filtered by the filter assembly 43 and discharged to the indoor air through the indoor air outlet 42, avoiding the overloading operation of the fresh air fan 5 when the fresh air inlet 41 is closed by the baffle, and avoiding the problem that the rotation of the fresh air fan 5 is accompanied by pneumatic noise, so that the airflow pressure in the fresh air module is kept stable.

[0224] Reference Figures 24-36 , which is an internal schematic view of another exemplary embodiment of the hanging air conditioner of the present application.

[0225] Reference Figure 26 The fresh air inlet 41 and the purification air inlet 40 are arranged on the first side wall 471, and the fresh air inlet 41 and the purification air inlet 40 are located in the middle of the first side wall 471. The fresh air inlet 41 and the purification air inlet 40 are arranged in the length direction of the first side wall 471.

[0226] In some embodiments of the present application, reference Figure 27 The baffle assembly can include a third baffle 8. The third baffle 8 is arranged on the fresh air volute 4 to open or close the fresh air function and / or the purification (indoor air internal circulation purification) function.

[0227] In some embodiments of the present application, the third baffle 8 is movably arranged on the fresh air volute 4.

[0228] The third baffle 8 can be moved in the thickness direction of the shell 1.

[0229] Reference Figure 29 Two openings are arranged on the third baffle 8, and the two openings are arranged in the length direction of the third baffle 8. One of the two openings can correspond to the fresh air inlet 41, and the other of the two openings can correspond to the purification air inlet 40.

[0230] It can be understood that when the third baffle 8 is in a certain position, the two openings are arranged one by one corresponding to the purification air inlet 40 and the fresh air inlet 41.

[0231] In some embodiments of the present application, the fresh air module can comprise a second driving device 10. The second driving device 10 is connected with the third baffle 8 to drive the third baffle 8 to move between different positions.

[0232] The positions where the third baffle 8 is located are defined as a fifth position, a sixth position, a seventh position and an eighth position. The second driving device 10 can drive the third baffle 8 to move and switch between the fifth position, the sixth position, the seventh position and the eighth position.

[0233] When the third baffle 8 is in the fifth position, the fresh air inlet 41 is separated from the fresh air duct 44, and the purification inlet 40 is separated from the fresh air duct 44.

[0234] Specifically, when the third baffle 8 is in the fifth position, the fresh air inlet 41 is separated from the fresh air duct 44 through the third baffle 8, so that the fresh air inlet 41 is in a closed state; the purification inlet 40 is separated from the fresh air duct 44 through the third baffle 8, so that the purification inlet 40 is in a closed state, and further so that the fresh air module is in a first state in which the fresh air function and the purification function of the wall-mounted air conditioner are simultaneously closed.

[0235] When the third baffle 8 is in the sixth position, the fresh air inlet 41 is connected with the fresh air duct 44 through one of the two openings, and the purification inlet 40 is separated from the fresh air duct 44.

[0236] Specifically, when the third baffle 8 is in the sixth position, the fresh air inlet 41 is connected with the fresh air duct 44 through the fourth opening 82 of the two openings, so that the fresh air inlet 41 is in an open state; the purification inlet 40 is separated from the fresh air duct 44 through the third baffle 8, so that the purification inlet 40 is in a closed state, so that the fresh air module is in a second state in which the fresh air inlet is opened and the purification inlet is closed, and in this state, the fresh air function of the wall-mounted air conditioner is opened, and the purification function is closed.

[0237] When the third baffle 8 is in the seventh position, the fresh air inlet 41 is connected with the fresh air duct 44 through one of the two openings, and the purification inlet 40 is connected with the fresh air duct 44 through the other opening.

[0238] Specifically, when the third baffle 8 is in the seventh position, the two openings are respectively and correspondingly arranged to be connected with the purification inlet 40 and the fresh air inlet 41, so that the fresh air inlet 41 and the purification inlet 40 are both in an open state, and further so that the fresh air module is in a third state in which the fresh air inlet and the purification inlet are simultaneously opened.

[0239] When the third baffle 8 is in the eighth position, the fresh air inlet 41 is disconnected from the fresh air duct 44, and the purification air inlet 40 is connected to the fresh air duct 44 through another one of the two openings in the sixth position.

[0240] Specifically, when the third baffle 8 is in the eighth position, the fresh air inlet 41 is disconnected from the fresh air duct 44 through the third baffle 8, so that the fresh air inlet 41 is in a closed state; the purification air inlet 40 is connected to the fresh air duct 44 through the third one of the two openings, so that the purification air inlet 40 is in an open state, so that the fresh air module is in a fourth state of fresh air inlet closed and purification air inlet open. In this state, the purification function of the wall-mounted air conditioner is opened, and the fresh air function is closed.

[0241] The wall-mounted air conditioner provided in the embodiment can control the movement of one third baffle 8 through one second driving device 10, so that the fifth position, the sixth position, the seventh position and the eighth position are switched, and the wall-mounted air conditioner has four working modes of single fresh air function, single purification function, purification function and fresh air function simultaneously opened, and purification function and fresh air function simultaneously closed, which is simple and convenient. The wall-mounted air conditioner can simultaneously carry the fresh air function and the purification function, and the user can select different working modes according to his own needs, thereby improving the user experience.

[0242] In some embodiments of the present application, the third baffle 8 can be moved from the fifth position to the sixth position, the seventh position and the eighth position in sequence, which facilitates the control of the second driving device 10.

[0243] In some embodiments of the present application, with reference to Figure 29 、 Figure 30 The second driving device 10 can include a second driving motor 101. The second driving motor 101 is installed on the fresh air volute 4.

[0244] The second driving device 10 can include a second gear 102. The second gear 102 is sleeved on the driving shaft of the second driving motor 101, and the driving shaft rotates to drive the second gear 102 to rotate synchronously.

[0245] The second driving device 10 can include a third rack 103. The third rack 103 is arranged on the third baffle 8, and the third rack 103 is engaged with the second gear 102. The second gear 102 rotates to drive the third rack 103 to move, and the third rack 103 moves to drive the third baffle 8 to move synchronously, so that the reciprocating movement of the third baffle 8 can be realized. Wherein, the third baffle 8 opens or closes the fresh air inlet 41 and / or the purification air inlet 40 through reciprocating movement.

[0246] In the embodiment, the first side wall is provided with a containing portion in communication with the fresh air duct 44. The containing portion is used for containing a gear, and a through hole is arranged on the containing portion, and the drive shaft of the second drive motor 101 is arranged in the through hole and fixedly connected with the second gear 102.

[0247] In some embodiments of the present application, with reference to Figure 30 , the fresh air volute 4 is provided with a third sliding portion 4434. The third sliding portion 4434 is used for sliding of the third baffle 8.

[0248] With reference to Figure 30 , the two ends of the first side wall 471 in the width direction are oppositely provided with the third sliding portion 4434. The third sliding portion 4434 can be in a sliding rail structure, and the two ends of the third baffle 8 in the width direction are respectively accommodated in the third sliding portion 4434.

[0249] In the embodiment, with reference to Figure 32 , the third sliding portion 4434 extends along the length direction of the first side wall 471.

[0250] The end of the third baffle 8 is accommodated in the third sliding portion 4434, and the third baffle 8 can slide along the extension direction of the third sliding portion 4434. By arranging the third sliding portion 4434, the movement track of the third baffle 8 is limited, and the linear motion of the third baffle 8 is realized, which is simple and convenient.

[0251] In some embodiments of the present application, when the third baffle 8 is in the fifth position, one end of the third baffle 8 in the length direction abuts against one end of the third sliding portion 4434 in the length direction. When the third baffle 8 is in the eighth position, the other end of the third baffle 8 abuts against the other end of the third sliding portion 4434.

[0252] With reference to Figure 32 , the two ends of the first side wall 471 in the length direction are respectively a front end and a rear end, and the two ends of the third baffle 8 in the length direction are respectively a front end and a rear end. Among them, the purification air inlet 40 is arranged relatively close to the front end of the first side wall 471 relative to the fresh air inlet 41.

[0253] Among the two through openings, the through opening arranged relatively close to the front end of the third baffle 8 is defined as the third through opening 81, and the through opening arranged relatively close to the rear end of the third baffle 8 is defined as the fourth through opening 82.

[0254] With reference to Figure 32 , when the third baffle 8 is in the fifth position, the rear end of the third baffle 8 abuts against the rear end of the third sliding portion 4434, and the front part of the third baffle 8 interrupts the communication between the fresh air inlet 41, the purification air inlet 40 and the fresh air duct 44, and simultaneously closes the fresh air and purification functions.

[0255] With reference to Figure 33When the third shutter 8 is in the sixth position, the fresh air inlet 41 is in communication with the fresh air duct 44 through the third through hole 81, and the front part of the third shutter 8 blocks the communication between the purification air inlet 40 and the fresh air duct 44, so that the fresh air function is turned on and the purification function is turned off.

[0256] When the third shutter 8 is in the sixth position, the fresh air fan 5 operates, outdoor fresh air enters the fresh air duct 44 through the fresh air inlet 41, and then flows to the indoor through the indoor air outlet 42 after being filtered by the filter assembly 43, so that the fresh air function of the wall-mounted air conditioner is turned on. Referring to Figure 33 , Figure 33 The dashed line depicted in FIG. 6 is used to represent the flow path of outdoor fresh air, and the arrow carried by the dashed line is used to represent the flow direction of outdoor fresh air.

[0257] When the third shutter 8 is in the seventh position, the purification air inlet 40 is in communication with the fresh air duct 44 through the third through hole 81, and the fresh air inlet 41 is in communication with the fresh air duct 44 through the fourth through hole 82, so that the fresh air function and the purification function are turned on at the same time.

[0258] Referring to Figure 34 When the third shutter 8 is in the seventh position, the fresh air fan 5 operates, outdoor fresh air enters the fresh air duct 44 through the fresh air inlet 41, and indoor air enters the fresh air duct 44 through the purification air inlet 40, and then the two are mixed and filtered by the filter assembly 43, and finally flow to the indoor through the indoor air outlet 42, so that the fresh air function and the purification function of the wall-mounted air conditioner are turned on at the same time, and outdoor fresh air introduction and indoor air internal circulation purification are realized.

[0259] In the eighth position of the third shutter 8, the front end of the third shutter 8 abuts against the front end of the third sliding part 4434, the rear part of the third shutter 8 blocks the communication between the fresh air inlet 41 and the fresh air duct 44, and the purification air inlet 40 is in communication with the fresh air duct 44 through the fourth through hole 82, so that the fresh air function is turned off and the purification function is turned on. Figure 34 Figure 34 The dashed line depicted in FIG. 6 is used to represent the flow path of outdoor fresh air, and the arrow carried by the dashed line is used to represent the flow direction of outdoor fresh air.

[0260] Referring to Figure 35 When the third shutter 8 is in the eighth position, the fresh air fan 5 operates, indoor air enters the fresh air duct 44 through the purification air inlet 40, and then flows to the indoor through the indoor air outlet 42 after being filtered by the filter assembly 43, so that the purification function of the wall-mounted air conditioner is turned on, and indoor air internal circulation purification is realized.

[0261] When the third shutter 8 is in the eighth position, the fresh air fan 5 operates, indoor air enters the fresh air duct 44 through the purification air inlet 40, and then flows to the indoor through the indoor air outlet 42 after being filtered by the filter assembly 43, so that the purification function of the wall-mounted air conditioner is turned on, and indoor air internal circulation purification is realized. Figure 35 , Figure 35 ​The solid line depicted in the figure represents the flow path of the indoor air, and the arrow on the solid line represents the flow direction of the indoor air.

[0262] In some embodiments of the present application, with reference to Figure 36 The distance between the purification air inlet 40 and the fresh air inlet 41 in the length direction of the first side wall 471 is a. Wherein, a≥6mm.

[0263] The distance a cannot be too small, otherwise it will cause air leakage between the fresh air inlet 41 and the purification air inlet 40 and make it inconvenient to connect the fresh air inlet 41. In order to separate the purification air inlet and the fresh air inlet and facilitate the connection of the fresh air inlet pipe, the distance a is set to be not less than a first parameter value. For example, the first numerical parameter can be 6mm, 6.5mm, or 7mm. A suitable specific parameter is selected in the specific design.

[0264] In some embodiments of the present application, with reference to Figure 36 The distance between the purification air inlet 40 and the fresh air inlet 41 in the length direction of the first side wall 471 is a. Wherein, a≤20mm.

[0265] The distance a cannot be too large, otherwise it will cause the thickness size of the fresh air module to be too large, and in turn cause the thickness size of the air conditioner indoor unit 100 of the wall-mounted air conditioner to be too large, increasing the overall machine size. In order to reduce the overall machine size, the distance a is set to be not more than a second parameter value. For example, the second numerical parameter can be 20mm, 19mm, or 18mm. A suitable specific parameter is selected in the specific design.

[0266] In some embodiments of the present application, with reference to Figure 36 The distance between the purification air inlet 40 and the fresh air inlet 41 in the length direction of the first side wall 471 is a. Wherein, 6mm≤a≤20mm. The distance a is set within a reasonable range, which effectively avoids air leakage between the two air inlets and effectively avoids increasing the overall machine thickness size.

[0267] In some embodiments of the present application, the first side wall 471 extends in the thickness direction of the shell, and the size of the fresh air inlet 41 in the thickness direction of the shell is L. Wherein, L≥15mm.

[0268] The size L cannot be too small, otherwise it will cause the fresh air inlet 41 to be not conducive to air inlet, and in turn cause the fresh air volume to be too small, the fresh air function effect to be not good, and the processing of the fresh air inlet 41 to be not conducive. In order to increase the fresh air inlet volume, the size L of the fresh air inlet 41 in the thickness direction of the shell 1 is set to be not less than a third parameter value. For example, the third numerical parameter can be 15mm, 15.5mm, or 16mm. A suitable specific parameter is selected in the specific design.

[0269] In some embodiments, the size of the fresh air inlet 41 in the thickness direction of the shell 1 is L. L≤40mm.

[0270] The size L cannot be too large, otherwise the thickness size of the fresh air module will be too large, and the thickness size of the air conditioner indoor unit 100 of the wall-mounted air conditioner will be too large, increasing the overall size. In order to reduce the overall size, the size L is set to be not more than a fourth parameter value. For example, the fourth numerical parameter can be 40mm, 39mm, or 38mm. A suitable specific parameter is selected in the specific design.

[0271] In some embodiments of the present application, the size of the fresh air inlet 41 in the thickness direction of the shell 1 is L. Wherein, L≥15mm, L≤25mm.

[0272] In the present embodiment, the size L of the fresh air inlet 41 is set to any value between 15mm and 25mm, which effectively avoids increasing the overall thickness size while ensuring the fresh air inlet amount.

[0273] In some embodiments of the present application, the size of the fresh air inlet 41 in the thickness direction of the shell 1 is L. Wherein, L>25mm, L≤40mm.

[0274] In the present embodiment, the size L of the fresh air inlet 41 is set to be greater than 15mm and between 15mm and 40mm, which can maximize the use of the overall thickness size. Under the limitation of the overall thickness size, the fresh air inlet 41 obtains the maximum air inlet area.

[0275] In some embodiments of the present application, the size of the fresh air inlet 41 in the thickness direction of the shell 1 is L, wherein 15mm≤L≤40mm.

[0276] In the present embodiment, the size L of the fresh air inlet 41 is set to any value between 15mm and 40mm, which ensures that the fresh air function has sufficient fresh air inlet amount while reducing the overall size, and facilitates the processing of the fresh air inlet 41.

[0277] In some embodiments of the present application, continuing to refer to Figure 36 , the size of the fresh air inlet 41 in the thickness direction of the shell 1 is L, and the thickness size of the first side wall 471 of the fresh air volute 4 in the thickness direction of the shell 1 is M, M≥8L.

[0278] In the present embodiment, the thickness size M of the first side wall 471 in the thickness direction of the shell 1 is approximately 8L. Taking the rear end of the first side wall 471 as the starting point, the fresh air inlet 41 is located at approximately the 4L position of the first side wall 471, and the purification air inlet 40 is located at approximately the 5L position of the first side wall 471.

[0279] The length of the third baffle 8 is not less than 5L. The third opening 81 is located at a position of 3L of the third baffle 8, and the fourth opening 82 is located at a position of 2L of the third baffle 8.

[0280] The hanging air conditioner provided in the embodiment can maximize the utilization of the thickness of the whole machine. Under the condition of the limited thickness, the fresh air inlet 41 and the purification air inlet 40 can obtain the maximum air inlet area.

[0281] In some embodiments of the present application, the air conditioner indoor unit 100 can include a third driving motor 113. The third driving motor 113 is installed on the base 11.

[0282] The third driving motor 113 is connected to one end of the heat exchange fan 3 away from the fresh air volute 4, and drives the heat exchange fan 3 to rotate. The other end of the heat exchange fan 3 is connected to the fresh air fan 5 through the connecting shaft 31.

[0283] In the embodiment, the use of the fresh air motor can be reduced by simultaneously driving the fresh air fan 5 and the heat exchange fan 3 with the single third driving motor 113, which saves the cost of the motor and makes the fresh air module smaller, thereby reducing the length of the whole machine, making the structure layout and design more reasonable, and saving the cost of plastic materials.

[0284] It can be understood that when the fresh air fan 5 and the heat exchange fan 3 are driven by the third driving motor 113, if the user does not want to introduce fresh air into the room and only wants to drive the heat exchange fan 3 to heat the indoor air, the third baffle 8 is slid to the eighth position to close the fresh air inlet 41, so as to avoid introducing fresh air into the room.

[0285] At this time, the heat exchange fan 3 is turned on to drive the fresh air fan 5 to rotate synchronously. Since the fresh air inlet 41 is closed, the rotation of the fresh air fan 5 drives the indoor air to enter the fresh air volute 4 through the purification air inlet 40. The indoor air entering the fresh air volute 4 is filtered by the filter assembly 43 and is discharged to the room through the indoor air outlet 42, avoiding the overloading operation of the fresh air fan 5 when the fresh air inlet 41 is closed by the third baffle 8, and further avoiding the problem that the rotation of the fresh air fan 5 is accompanied by aerodynamic noise, so that the airflow pressure in the fresh air module remains stable.

[0286] In some embodiments of the present application, the ratio of the air inlet area of the fresh air inlet 41 to the air inlet area of the purification air inlet 40 is in the range of 1-2. By setting the ratio of the air inlet area of the fresh air inlet 41 to the air inlet area of the purification air inlet 40 within a reasonable range, the fresh air function and the purification function are approximately equivalent when they are turned on.

[0287] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the present application; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
