[0063] Combine the following Figures 1 to 3The filtering and sterilizing component of this embodiment is described in detail. Figure 1 It is a schematic diagram of the structure of the sterilizing cotton in the filtering and sterilizing assembly according to one embodiment of the utility model; Figure 2 It is an exploded schematic diagram of a fresh air mechanism in a vertical air conditioner indoor unit according to an embodiment of the utility model; Figure 3 is along Figure 2 Enlarged schematic diagram of point "A" in the figure.

[0064] Reference Figure 1 , Figure 2 In this embodiment, the filter sterilization assembly 100 includes a filter body 110 and a sterilizing cotton 120. The filter body 110 is used to filter the airflow passing through it; the sterilizing cotton 120 is used to sterilize the airflow passing through it, and a receiving cavity 121 is provided in the sterilizing cotton 120, and a replacement port 122 connected to the receiving cavity 121 is provided on the sterilizing cotton 120. The filter body 110 is provided in the receiving cavity 121, and the replacement port 122 is used to allow the filter body 110 to be loaded into the receiving cavity 121 from the outside of the sterilizing cotton 120, and the replacement port 122 is used to allow the filter body 110 to be removed from the receiving cavity 121 to the outside of the sterilizing cotton 120.

[0065] Since the filter sterilization component 100 of this embodiment has sterilizing cotton 120, a receiving cavity 121 for receiving the filter body 110 is provided in the sterilizing cotton 120, and a replacement port 122 connected to the receiving cavity 121 is provided on the sterilizing cotton 120. That is, the sterilizing cotton 120 is in the shape of a pocket. Therefore, when the user / maintenance and repair personnel replace the sterilizing cotton 120 or the filter body 110, they can directly load the filter body 110 from the outside of the sterilizing cotton 120 into the receiving cavity 121 from the replacement port 122, and there is no need to fix the sterilizing cotton 120 and the filter body 110 to each other; or when the filter body 110 is directly removed from the receiving cavity 121 from the replacement port 122, there is no need to clean the adhesive, and at the same time, the situation of the sterilizing cotton 120 being disassembled is effectively avoided. Therefore, the filter sterilization component 100 of this embodiment can ensure the replaceability of the sterilizing cotton 120, and the convenience of the filter body 110 or the sterilizing cotton 120 being replaceable.

[0066] In addition, in the prior art, since the sterilizing cotton 120 is attached / bonded to the filter body 110 (filter element / filter screen) in a single layer, when the airflow flows through such a filter component, the sterilizing effect on the airflow is poor. In addition, sterilizing cotton 120 can be placed in front and behind the filter body 110 to achieve at least two sterilizations of the airflow passing through it. However, in this way, when replacing the filter body 110 or the sterilizing cotton 120, two replacement operations are required, resulting in an inconvenient replacement process. Moreover, the front and rear sterilizing cotton 120 can also be directly set as an integrated product with the filter body 110. In this way, the filter body 110 or the sterilizing cotton 120 cannot be replaced, and the replaceability of the sterilizing cotton 120 is difficult to ensure.

[0067] Reference Figure 1 , Figure 2 In this embodiment, the sterilization cotton 120 includes a first sterilization layer 123 located on the front side of the filter body 110 and a second sterilization layer 124 located on the rear side of the filter body 110. The first sterilization layer 123 and the second sterilization layer 124 are used to sterilize the airflow flowing through the filter sterilization component 100 twice.

[0068] It is understandable that since the sterilizing cotton 120 is a pocket-shaped structure with a containing cavity 121 and a replacement port 122, that is, the sterilizing cotton 120 is wrapped around the filter body 110. Furthermore, such a filter sterilization component 100 may at least include a first sterilization layer 123 located on the front side of the filter body 110 and a second sterilization layer 124 located on the rear side of the filter body 110. Therefore, in the process of replacing the filter body 110 / sterilizing cotton 120, the filter body 110 can be directly loaded with the sterilizing cotton 120 or the sterilizing cotton 120 can be taken off from the filter body 110. While ensuring that the airflow can be sterilized at least twice, the filter body 110 / sterilizing cotton 120 can be replaced at one time, and the replacement process is very convenient. In addition, the replaceability of the filter body 110 / sterilizing cotton 120 can be well guaranteed.

[0069] Reference Figure 1 , Figure 2 In this embodiment, the replacement port 122 is located at the left end, right end, top end or bottom end of the sterilization cotton 120.

[0070] It is understandable that, since the filter 110 is in the shape of a plate or paper, by setting the replacement port 122 at the left end, right end, top end or bottom end of the sterilizing cotton 120, the filter 110 can be smoothly loaded into or removed from the sterilizing cotton 120. In addition, if the replacement port 122 is set at the front side or rear side of the sterilizing cotton 120, the airflow may pass through the sterilizing cotton 120 through the replacement port 122, and thus the sterilization effect will be greatly reduced. Therefore, the present sterilizing cotton 120 can have a good sterilization effect.

[0071] In this embodiment, the filter body 110 may be a filter screen.

[0072] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the filter body 110 is a filter element, and the filter element has a filter surface 111 located behind the first sterilization layer 123, and the filter surface 111 is wavy.

[0073] It is understandable that setting the filter surface 111 to be wavy can well ensure the effective filter surface area of ​​the filter surface 111 to ensure the sterilization effect of the filter element / filter sterilization component 100.

[0074] In this embodiment, aromatherapy material is attached to the filter surface 111 to adjust the smell of the airflow passing through the filter body 110 .

[0075] It is understandable that, through the setting of aromatherapy materials, the air in the indoor space where the air treatment equipment works can be kept fresh continuously, so as to greatly ensure the user experience. In particular, when the air treatment equipment is an indoor unit of an air conditioner, the filter sterilization component 100 can be used to filter and sterilize the fresh air flow, or it can be the indoor air flow that is circulated indoors through heating and cooling. Since the indoor air flow needs to circulate indoors within a certain period of time, there is no outdoor fresh air flow to supplement the indoor space. Therefore, the long-term operation of the air conditioner will make the air in the indoor space unacceptable to the user. Furthermore, the airflow through the filter sterilization component 100 with aromatherapy materials attached can carry the odor molecules of the aromatherapy materials to the indoor space to cover the original smell of the indoor space, thereby ensuring the user experience.

[0076] In this embodiment, the aromatherapy material is located at the bottom of the wave structure of the filter surface 111 .

[0077] It can be understood that when the airflow to be processed passes through the wavy filter surface 111, the airflow will be guided by the wave structure from the top of the wave structure to the bottom of the wave structure. Therefore, setting the aromatherapy material at the bottom of the wave structure of the filter surface 111 can ensure that the airflow can carry a larger amount of gas molecules of the aromatherapy material, ensure the effect of covering the original smell of the indoor space, and ensure user experience.

[0078] Reference Figure 1 , Figure 2In this embodiment, the filter sterilization component 100 includes a first filter support 130 and a second filter support 140. A filter cavity 131 is provided on the first filter support 130, and a first through hole 132 communicating with the filter cavity 131 is provided on the rear side of the first filter support 130, and a placement opening 133 communicating with the filter cavity 131 is provided on the front side of the first filter support 130. The sterilization cotton 120 is provided in the filter cavity 131, and the first sterilization layer 123 is provided toward the placement opening 133; the second filter support 140 is detachably provided at the placement opening 133, and a second through hole 141 communicating with the filter cavity 131 is provided on the second filter support 140.

[0079] It is understandable that by providing the first filter support 130 and the second filter support 140, the stability of the assembly of the filter body 110 and the sterilizing cotton 120 can be ensured, while ensuring the convenience and assembly stability of the filter sterilization component 100 when assembled into the air treatment equipment.

[0080] Reference Figure 1 , Figure 2 In this embodiment, a replacement handle 134 is provided on the first filter support 130 to facilitate the replacement operation of the filter sterilization component 100.

[0081] Combine the following Figures 4 to 11 The air duct components of the air conditioner indoor unit of this embodiment will be described in detail. Figure 4 This is one of the structural schematic diagrams of the air duct member according to one embodiment of the utility model; Figure 5 yes Figure 4 An enlarged schematic diagram of the area "B" in the figure; Figure 6 It is a partial structural schematic diagram of an air duct shell in an air duct member according to an embodiment of the utility model; Figure 7 This is one of the structural schematic diagrams of the second housing in the air duct member according to one embodiment of the utility model; Figure 8 yes Figure 7 The enlarged schematic diagram of the "C" in the middle; Fig. 9 This is a second structural schematic diagram of the second shell of the air duct member according to an embodiment of the utility model; Fig.10 3 is a schematic diagram of the structure of the second shell of the air duct member according to an embodiment of the utility model, wherein Fig.10 The dotted frame in the figure indicates two rotation positions / rotation states of the air guide body; Fig.11 It is a structural schematic diagram of an air guide body in an air duct member according to an embodiment of the utility model.

[0082] In the prior art, this type of air handling equipment may cause the problem of too hard airflow when delivering air to the indoor space. For example, when the user corresponds to the air outlet of the air handling equipment, or when the treated airflow is directed toward the user's location, the treated airflow blows directly onto the user, causing great discomfort to the user, resulting in a significant reduction in the user experience of the air handling equipment.

[0083] Reference Figure 4 and Figure 5 In the present embodiment, the duct member of the indoor unit of the air conditioner includes a duct shell 200, in which a duct cavity 210 is arranged, and the duct cavity 210 is used to transport the outlet air flow to the indoor space where the indoor unit of the air conditioner is located through the air outlet portion of the indoor unit of the air conditioner, and the inner wall surface of the duct cavity 210 is recessed to be provided with at least one soft air cavity 211, and the soft air cavity 211 is used to guide the outlet air flow to flow therethrough, so as to slow down the flow velocity of the outlet air flow flowing out of the air outlet portion.

[0084] Since the inner wall surface of the duct cavity 210 of the duct shell 200 of the air duct member of the air conditioner indoor unit of this embodiment is recessed and provided with at least one soft air cavity 211, the soft air cavity 211 can guide the outlet air flow to flow therein, so as to slow down the flow rate of the outlet air flow out of the air outlet portion. Therefore, the air duct member of the air conditioner indoor unit of this embodiment can soften the outlet air flow of the vertical air conditioner indoor unit, the air conditioner indoor unit and its air duct member, so that when the outlet air flow blows on the user, the user will not feel that the air flow is too hard, thereby ensuring the user experience of the vertical air conditioner indoor unit and the air conditioner indoor unit.

[0085] It should be noted that the air outlet may be the first vent 530 and / or the second vent 540 in the following embodiments.

[0086] In some embodiments, the shape of the soft wind chamber 211 may be rectangular.

[0087] In other embodiments, the cavity wall of the soft wind cavity 211 may be an irregular concave-convex surface.

[0088] It should be understood that when the duct member delivers the outlet airflow to the indoor space through the duct cavity 210, if the angle between the inner wall of the soft wind cavity 211 and the inner wall of the duct cavity 210 is too large, and the connection between the inner wall of the soft wind cavity 211 and the inner wall of the duct cavity 210 is not smooth enough, it is difficult for the outlet airflow to flow from the duct cavity 210 into the soft wind cavity 211, or it is difficult for the outlet airflow to flow back from the soft wind cavity 211 to the duct cavity 210. Alternatively, if the cavity wall of the soft wind cavity 211 is irregular, the outlet airflow is likely to be turbulent in the soft wind cavity 211 after entering the soft wind cavity 211. Furthermore, when the shape of the soft wind cavity 211 is rectangular or the cavity wall of the soft wind cavity 211 is irregular, the outlet airflow will suffer great wind loss when flowing through the soft wind cavity 211. This will reduce the working performance of the air handling equipment, such as the indoor heating performance and cooling performance of the air conditioner, the dehumidification performance of the dehumidifier, the purification performance of the purifier, etc.

[0089] Reference Figure 4 , Figure 5 and Figure 6 In the present embodiment, the cavity wall surface of the soft wind cavity 211 is spherical to guide the outgoing air flow into and out of the soft wind cavity 211 and to regularize the flow path of the outgoing air flow in the soft wind cavity 211 .

[0090] It should be understood that when the wall surface of the soft wind chamber 211 is spherical, the angle between the inner wall of the soft wind chamber 211 and the inner wall of the air duct chamber 210 is very small, and the connection between the inner wall of the soft wind chamber 211 and the inner wall of the air duct chamber 210 is very gentle, and the outlet airflow can easily flow from the air duct chamber 210 into the soft wind chamber 211, or the outlet airflow can easily flow back from the soft wind chamber 211 into the air duct chamber 210. Moreover, at this time, the wall of the soft wind chamber 211 is regular, and after the outlet airflow enters the soft wind chamber 211, a regular gas vortex will be generated in the soft wind chamber 211, and along the flow of the vortex and the flow of the outlet airflow in the air duct chamber 210, it will flow smoothly back to the air duct chamber 210. Furthermore, by setting the cavity wall surface of the soft wind cavity 211 to be a spherical surface, the wind loss of the outlet air flow when flowing through the soft wind cavity 211 can be greatly reduced or even eliminated, so as to ensure the working performance of the air treatment equipment.

[0091] Reference Figure 4 , Figure 5 and Figure 6 In this embodiment, the depth G of the soft wind cavity 211 ranges from 0.25 mm to 0.35 mm.

[0092] It should be understood that the depth of the soft wind cavity 211 can determine the length of time that the outlet airflow flows in the soft wind cavity 211, and as the depth of the soft wind cavity 211 increases, the length of time that the outlet airflow flows in the soft wind cavity 211 increases. If the outlet airflow flows in the soft wind cavity 211 for a long time, it may cause the outlet airflow in the soft wind cavity 211 to have a large wind loss. If the outlet airflow flows in the soft wind cavity 211 for a short time, the function of the soft wind cavity 211 to soften the outlet airflow is difficult to ensure.

[0093] Therefore, the depth of the soft wind chamber 211 is set to be in the range of 0.25 mm to 0.35 mm. Then, the depth of the soft wind chamber 211 is appropriate, and the flow time in the soft wind chamber 211 is appropriate, which can well ensure the softening effect of the soft wind chamber 211 on the outlet airflow and greatly reduce the wind loss of the outlet airflow.

[0094] Reference Figure 4 , Figure 5 and Figure 6 In this embodiment, the angle H between the tangent line at any point where the cavity wall surface and the inner wall surface are connected and the inner wall surface is in the range of 9 degrees to 11 degrees.

[0095] It is understandable that by setting the angle between the tangent line at any point of the connection between the cavity wall and the inner wall and the inner wall to 9 to 11 degrees, a large angle between the inner wall of the soft wind cavity 211 and the inner wall of the air duct cavity 210 can be avoided, and the outlet airflow can have a more suitable flow time in the soft wind cavity 211. The softening effect of the soft wind cavity 211 is ensured, and wind loss of the outlet airflow in the soft wind cavity 211 is avoided.

[0096] Reference Figure 4 and Figure 5 In this embodiment, the number of the soft wind chambers 211 is set to be multiple, and the multiple soft wind chambers 211 are arranged adjacent to each other to ensure the overall performance of the air duct member in softening the outlet air flow.

[0097] Reference Figure 4 and Figure 5 In this embodiment, the shape of the cavity opening of the soft wind cavity 211 is hexagonal, and the cavity openings of two adjacent soft wind cavities 211 have a common edge, and the adjacent multiple soft wind cavities 211 are honeycomb-shaped as a whole.

[0098] It can be understood that through the hexagonal cavity opening and the honeycomb structure of the inner wall of the air duct cavity 210, if noise propagates in the air duct cavity 210, the noise will be reflected, refracted and dispersed by the honeycomb structure multiple times, and the sound wave energy of the noise will be absorbed and dissipated to eliminate the noise in the air duct cavity 210 to ensure the user experience.

[0099] Reference Figure 4In the present embodiment, the air duct shell 200 is provided with an air duct inlet 220 connected to the air duct cavity 210 , and the air duct cavity 210 includes a plurality of air outlet ducts connected to the air duct inlet 220 , and the plurality of air outlet ducts are connected at the air duct inlet 220 .

[0100] It can be understood that the air duct cavity 210 of this embodiment can be configured as a plurality of air outlet ducts, so that the air duct member can supply air to a plurality of components / directions of the air handling device (eg, a vertical air conditioner indoor unit).

[0101] Reference Figure 7 , Fig. 9 and Fig.10 In the present embodiment, the duct shell 200 is provided with an duct inlet 220 connected to the duct cavity 210 , and the duct cavity 210 includes a first air outlet duct 212 and a second air outlet duct 213 connected to the duct inlet 220 , and the first air outlet duct 212 and the second air outlet duct 213 are connected at the duct inlet 220 .

[0102] It is understandable that the duct cavity 210 of this embodiment can be set as a first air outlet duct 212 and a second air outlet duct 213, so that the duct member of this embodiment can supply air to multiple components / directions of the air handling equipment (for example, a vertical air conditioner indoor unit).

[0103] Reference Figure 7 , Fig. 9 and Fig.10 In this embodiment, the first air outlet duct 212 and the second air outlet duct 213 extend in opposite directions from the air duct inlet 220, so that the air duct member of this embodiment can supply air in two opposite directions, or supply air to two oppositely arranged components of the air handling device (for example, a vertical air conditioner indoor unit).

[0104] However, due to the large arrangement angles between the multiple outlet ducts, the airflow from the fan needs to change direction when flowing to the multiple outlet ducts. Especially when the duct structure is to deliver air in two opposite directions, the airflow is prone to impact and form vortices at the intersection of the fan and the multiple outlet ducts. This will reduce the air outlet efficiency of the duct structure and affect the working performance of the air handling equipment with the duct structure. In addition, since the shape of the intersection is fixed, the flow rate of the airflow from the fan to each outlet duct is fixed and cannot meet the user's demand for changes in the airflow flow in any direction, greatly reducing the user experience.

[0105] Reference Figure 7 , Fig. 9 and Fig.10In this embodiment, the air duct component of the air conditioner indoor unit includes an air guide body 300. The air guide body 300 is rotatably disposed in the air duct cavity 210, the air guide body 300 is disposed corresponding to the air duct inlet 220, and the air guide body 300 is located between the first air outlet duct 212 and the second air outlet duct 213, the air guide body 300 has a first air guide slope 310 facing the air duct inlet 220 and the first air outlet duct 212, and the air guide body 300 has a second air guide slope 320 facing the air duct inlet 220 and the second air outlet duct 213, the air guide body 300 also has a connecting end 330 facing the air duct inlet 220, and the first air guide slope 310 and the second air guide slope 320 are connected at the connecting end 330, and the connecting end 330 is rotatably disposed around the rotation center axis of the air guide body 300 toward the first air outlet duct 212 or the second air outlet duct 213 to adjust the flow rate of airflow entering the first air outlet duct 212 and the second air outlet duct 213.

[0106] The air duct member of the indoor unit of the air conditioner of the utility model has an air guide body 300 arranged in the air duct cavity 210 thereof. Specifically, the air guide body 300 is arranged corresponding to the air duct inlet 220 and is located between the first air outlet duct 212 and the second air outlet duct 213 of the air duct cavity 210. In addition, the air guide body 300 has a first air guide slope 310 facing the air duct inlet 220 and the first air outlet duct 212, and has a second air guide slope 320 facing the air duct inlet 220 and the second air outlet duct 213, and also has a connecting end 330 facing the air duct inlet 220, so that the air guide body 300 can guide the airflow entering the air duct cavity 210 from the air duct inlet 220 to the first air outlet duct 212 and the second air outlet duct 213 respectively, so as to suppress the generation of vortex. Meanwhile, the air guide body 300 is rotatably disposed in the air duct cavity 210. Specifically, the connection end 330 is rotatably disposed around the rotation center axis of the air guide body 300 toward the first air outlet duct 212 or the second air outlet duct 213, so that the air guide body 300 can adjust the flow rate of the airflow entering the first air outlet duct 212 and the second air outlet duct 213. Therefore, the utility model can ensure the air outlet efficiency of the air duct member and the (vertical) air conditioner indoor unit, ensure the working performance of the (vertical) air conditioner indoor unit, and at the same time, enable the air duct member and the (vertical) air conditioner indoor unit to meet the user's demand for variable airflow in any direction, thereby ensuring user experience.

[0107] Reference Figure 7 , Fig. 9 and Fig.10In the present embodiment, the air duct inlet 220 is located at the bottom of the air duct shell 200, and the first air outlet duct 212 extends forward, the second air outlet duct 213 extends backward, and the rotation center axis of the air guide body 300 is arranged in the middle of the air duct inlet 220 in the front-to-back direction; and, the angle M between the first air guide slope 310 and the second air guide slope 320 is in the range of 25 degrees to 35 degrees; and, the maximum angle N of the connection end 330 rotating around the rotation center axis of the air guide body 300 toward the first air outlet duct 212 is in the range of 10 degrees to 20 degrees, and the maximum angle P of the connection end 330 rotating around the rotation center axis of the air guide body 300 toward the second air outlet duct 213 is in the range of 10 degrees to 20 degrees.

[0108] It should be understood that the angle between the first air guiding slope 310 and the second air guiding slope 320 is in the range of 25 degrees to 35 degrees, so that the air guiding body 300 can achieve the function of guiding the airflow entering the air duct cavity 210 from the air duct inlet 220 to the first air outlet duct 212 and the second air outlet duct 213 respectively, while the airflow entering the air duct cavity 210 from the air duct inlet 220 to the first air outlet duct 212 and the second air outlet duct 213 will not be affected by the excessive angle between the first air guiding slope 310 and the second air guiding slope 320. For example, the angle between the first air guiding slope 310 and the second air guiding slope 320 can be 10 degrees, 15 degrees, 20 degrees, 35 degrees, etc. Preferably, the angle between the first air guiding slope 310 and the second air guiding slope 320 is in the range of 30 degrees.

[0109] Furthermore, the air guide body 300 may have a first state in which the airflow rate flowing into the first air outlet duct 212 is adjusted to a maximum value and the airflow rate flowing into the second air outlet duct 213 is adjusted to a minimum value, in which the connection end 330 rotates to a maximum angle around the rotation center axis of the air guide body 300 toward the second air outlet duct 213. Furthermore, the air guide body 300 may have a second state in which the airflow rate flowing into the second air outlet duct 213 is adjusted to a maximum value and the airflow rate flowing into the first air outlet duct 212 is adjusted to a minimum value, in which the connection end 330 rotates to a maximum angle around the rotation center axis of the air guide body 300 toward the first air outlet duct 212. Furthermore, the maximum angle of the connection end 330 rotating around the rotation center axis of the air guide body 300 toward the first air outlet duct 212 is in the range of 10 to 20 degrees, and the maximum angle of the connection end 330 rotating around the rotation center axis of the air guide body 300 toward the second air outlet duct 213 is in the range of 10 to 20 degrees. Within this range, the air guide body 300 can simultaneously play a role in the airflow flowing to the first air outlet duct 212 and the second air outlet duct 213 to ensure the normal operation of the air duct member. For example, the maximum angle can be 10 degrees, 12 degrees, 14 degrees, 16 degrees, 18 degrees, 20 degrees, etc. Preferably, the maximum angle can be set to 15 degrees.

[0110] Reference Fig.11 In this embodiment, the air guide body 300 includes a first air guide plate 340, a second air guide plate 350, a first connecting plate 360 ​​and a second connecting plate 370. The bottom end of the second air guide plate 350 is connected to the bottom end of the first air guide plate 340, and the second air guide plate 350 and the first air guide plate 340 are arranged at a preset angle, the first air guide slope 310 is located on the outer side of the first air guide plate 340, and the second air guide slope 320 is located on the outer side of the second air guide plate 350; the first connecting plate 360 ​​is connected to the left end of the first air guide plate 340 and the left end of the second air guide plate 350; the second connecting plate 370 is connected to the right end of the second air guide plate 350 and the right end of the second air guide plate 350.

[0111] It can be understood that the value of the preset angle may be the same as the value of the included angle between the first wind guiding slope 310 and the second wind guiding slope 320 .

[0112] Reference Fig.11 In the present embodiment, a weight reduction cavity 341 is provided on the air guide body 300, and the weight reduction cavity 341 is located between the first air guide plate 340, the second air guide plate 350, the first connecting plate 360 ​​and the second connecting plate 370, and the weight reduction cavity 341 is in a closed state at the first air guide plate 340, the second air guide plate 350, the first connecting plate 360 ​​and the second connecting plate 370.

[0114] Reference Figure 4 and Fig.11 In this embodiment, the air duct member further includes a driving device 400. The driving device 400 is disposed on the air duct housing 200 and is drivingly connected to the air guide body 300. The driving device 400 is used to drive the air guide body 300 to rotate. In this way, the air guide body 300 is driven to rotate.

This enables the air duct member to transport airflow in two opposite directions.

[0117] Reference Figure 7 , Fig. 9 and Fig.10 In the present embodiment, a portion of the first air outlet duct 212 close to the first air outlet 230 has a width I in at least the up-down direction that is greater than a width J in a portion of the first air outlet duct 212 close to the air duct inlet 220; and a portion of the second air outlet duct 213 close to the second air outlet 240 has a width K in at least the up-down direction that is greater than a width L in a portion of the second air outlet duct 213 close to the air duct inlet 220.

[0122] In this embodiment, the vertical air conditioner indoor unit comprises a housing 500 and the air duct member of the above embodiment. Furthermore, the vertical air conditioner indoor unit of the utility model also has the beneficial technical effects of the above air duct member.

[0123] Reference Fig.12 , Fig.14 and Fig.18 In this embodiment, a heat exchange air inlet 510 is provided on the shell 500, and a heat exchange air outlet 520 is provided on the front side of the shell 500, and a heat exchange air duct is connected between the heat exchange air inlet 510 and the heat exchange air outlet 520 inside the shell 500, and the indoor heat exchanger is arranged in the heat exchange air duct, so that the heat exchange air outlet 520 can flow out the heat exchange airflow that flows through the indoor heat exchanger of the vertical air conditioner indoor unit.

[0124] It can be further understood that when the indoor heat exchanger is configured as an evaporator, the vertical air conditioner indoor unit of this embodiment can cause the indoor airflow to enter the heat exchange air duct through the heat exchange air inlet 510, and the indoor airflow forms a heat exchange airflow, i.e., a cooling airflow, after heat exchange with the indoor heat exchanger, and the cooling airflow is blown out to the indoor space through the heat exchange air outlet 520, so as to realize the operation of the cooling mode. When the indoor heat exchanger is configured as a condenser, the vertical air conditioner indoor unit of this embodiment can cause the indoor airflow to enter the heat exchange air duct through the heat exchange air inlet 510, and the indoor airflow forms a heat exchange airflow, i.e., a heating airflow, after heat exchange with the indoor heat exchanger, and the heating airflow is blown out to the indoor space through the heat exchange air outlet 520, so as to realize the operation of the heating mode. When the indoor heat exchanger is not working, the vertical air conditioner indoor unit of this embodiment can simply blow air into the room, so as to realize the ventilation mode of neither cooling nor heating.

[0125] Reference Fig.12 , Fig.13 , Fig.16 and Fig.17 In this embodiment, the vertical air conditioner indoor unit includes a fresh air mechanism 600. A first vent 530 is provided on the front side of the housing 500; the fresh air mechanism 600 is provided in the housing 500, the fresh air mechanism 600 is connected to the first vent 530 and the outdoor space, and the fresh air mechanism 600 is used to introduce the fresh air flow of the outdoor space into it; and the air duct shell 200 is provided in the housing 500, the air inlet end (air duct air inlet 220) of the first air outlet duct 212 of the air duct member is connected to the fresh air mechanism 600, and the air outlet end (first air outlet 230) of the first air outlet duct 212 is connected to the first vent 530, and the first air outlet duct 212 is used to transport the air flow in the fresh air mechanism 600 forward to the indoor space through the first vent 530.

[0126] It is understandable that the vertical air conditioner indoor unit of this embodiment can transport the fresh air flow from the outdoor space to the indoor space through the arrangement of the fresh air mechanism 600, so as to ensure the physical and mental health of the user and improve the user experience. The user will feel the fresh air blowing on his face, which further improves the user experience.

[0127] At present, in the prior art, during most of the time when the air conditioner is running, there is a large difference between the ambient temperature of the indoor space and the ambient temperature of the outdoor space. For example, in winter, when the air conditioner is running in cooling mode; or in summer, when the air conditioner is running in heating mode. In this way, there is a large temperature difference between the fresh air flow delivered to the room by the fresh air module and the ambient temperature of the indoor space, which will cause great discomfort to the user of the air conditioner, resulting in a reduced user experience.

[0128] Reference Fig.14 , Fig.15In this embodiment, a first circulation air outlet 550 is provided on the shell 500, and the fresh air mechanism 600 is connected to the first circulation air outlet 550; and the fresh air mechanism 600 is also used to introduce the indoor air flow of the indoor space where the vertical air conditioner indoor unit is located into it through the first circulation air outlet 550, and the fresh air mechanism 600 is used to promote the mixing of the fresh air flow and the indoor air flow to form a mixed air flow.

[0129] It is understandable that the first air outlet duct 212 can deliver the mixed airflow to the indoor space through the first vent 530. Furthermore, the vertical air conditioner indoor unit of this embodiment can first mix the fresh airflow with the indoor airflow circulating in the room before delivering it to the indoor space, which can reduce the temperature difference between the fresh airflow and the indoor airflow, effectively reduce the user's discomfort caused by the inconsistency between the outdoor fresh airflow and the ambient temperature of the indoor space, and thus the vertical air conditioner indoor unit of this embodiment can effectively improve the user's experience.

[0130] However, after the fresh air flow is mixed with the indoor air flow in the fresh air mechanism 600 to form a mixed air flow, after being blown out of the housing 500 into and out of the indoor space, there is still a certain difference with the indoor temperature, which may still cause a temperature difference sensation to the human body.

[0131] Figure 7 , Figure 8 , Fig. 9 and Fig.10 In the present embodiment, a first air outlet duct 212 is provided in the air duct shell 200 (i.e., the air duct cavity 210 includes the first air outlet duct 212), and an air guide surface 715 is provided in the first air outlet duct 212 and / or at the first vent 530, and an air outlet end of the air guide surface 715 is inclined toward the first vent 530 to guide the mixed air flow to flow toward the front of the heat exchange air outlet 520 and mix with the heat exchange air flow.

[0132] Reference Fig.18 The vertical air conditioner indoor unit of this embodiment has a fresh air mechanism 600 and an air duct shell 200, and the fresh air mechanism 600 can mix the fresh air flow and the indoor air flow once and then deliver them to the indoor space, so as to reduce the temperature difference between the fresh air flow and the ambient temperature of the indoor space. At the same time, an air guide surface 715 is provided in the first air outlet duct 212 and / or at the first vent 530, and the air outlet end of the air guide surface 715 is inclined toward the first vent 530, and then the air guide surface 715 can mix the mixed air flow formed by the primary mixing with the heat exchange air flow in front of the heat exchange outlet 520 for a second time, and then deliver the mixed air flow after the second mixing to the indoor space, so as to further reduce the temperature difference between the fresh air flow and the ambient temperature of the indoor space. At the same time, the discomfort caused to the user by the temperature difference zone described in the following embodiments will be greatly reduced. Therefore, the vertical air conditioner indoor unit of this embodiment can greatly improve the user experience.

[0133] Reference Fig.19 In this embodiment, the vertical air conditioner indoor unit further includes at least one first air mixing outlet grille 810 disposed at the first vent 530. The shapes of the air outlet holes on each first air mixing outlet grille 810 may be different, for example, the air outlet holes may be arranged in a circular, triangular, strip, etc. And the first air mixing outlet grille 810 may divide the mixed air flow flowing out of the first vent so that the mixed air flow will not make the user feel too hard, soften the mixed air flow, and ensure the user experience. In addition, multiple first air mixing outlet grilles 810 may be arranged to be stacked at the first vent 530 to further soften the mixed air flow and ensure the user experience.

[0134] In some embodiments, the first vent 530 is located below the heat exchange outlet 520; and the vertical air conditioner indoor unit includes an air induction plate. The air induction plate is disposed at the first vent 530 and is arranged upwardly in an inclined direction from the back to the front, and the air guide surface 715 includes the top side of the air induction plate.

[0135] Furthermore, the vertical air-conditioning indoor unit of the present embodiment can guide the mixed air flow toward the front of the heat exchange air outlet 520 to be mixed with the heat exchange air flow for the second time by disposing the air guide plate.

[0136] In addition, the air induction plate may be a portion of the first air mixing outlet grille 810 where no air outlet holes are provided.

[0137] In other embodiments, the first ventilation port 530 is located below the heat exchange outlet 520 ; and the first air outlet duct 212 is arranged obliquely upward from the back to the front, and the air guide surface 715 includes an inner bottom wall of the first air outlet duct 212 .

[0138] Furthermore, the vertical air-conditioning indoor unit of this embodiment can achieve secondary mixing of the mixed air flow with the heat exchange air flow by tilting the first air outlet duct 212 to guide the mixed air flow toward the front of the heat exchange air outlet 520 .

Specifically, the air guide plate, the first air outlet duct 212, and / or the first guide plate 711 may be arranged obliquely to guide the mixed air flow toward the front of the heat exchange outlet 520 for secondary mixing with the heat exchange air flow.

[0142] For example, when the first vent 530 is set on the left side of the heat exchange air outlet, and the air induced plate is set vertically, and the air outlet end of the air induced plate is tilted to the right, and / or the air outlet end of the first air outlet duct 212 is tilted to the right, and / or the air outlet end of the first guide plate 711 is tilted to the right; when the first vent 530 is set on the right side of the heat exchange air outlet, and the air induced plate is set vertically, and the air outlet end of the air induced plate is tilted to the left, and / or the air outlet end of the first air outlet duct 212 is tilted to the left, and / or the air outlet end of the first guide plate 711 is tilted to the left; when the first vent 530 is set above the heat exchange air outlet, and the air induced plate is set horizontally, and the air outlet end of the air induced plate is tilted downward, and / or the air outlet end of the first air outlet duct 212 is tilted downward, and / or the air outlet end of the first guide plate 711 is tilted downward.

The right end of the second air guide plate 712 is connected to the right inner wall of the second shell 260, the left end of the second air guide plate 712 extends to the left inner wall of the second shell 260, and the second air guide plate 712 is arranged obliquely upward along the direction of the mixed air flow flowing in the first air outlet duct 212, and the air guide surface 715 also includes the top side surface of the second air guide plate 712; the first support plate 713 is arranged in the up-down direction, the end of the first support plate 713 is connected to the top wall and / or the bottom wall of the first shell 250, the first support plate 713 is located between the first air guide plate 711 and the second air guide plate 712, and the right end of the first air guide plate 711 is connected to the first support plate 713; the second support plate 714 is arranged in the up-down direction, and the end of the second support plate 714 is connected to the top wall and / or the bottom wall of the second shell 260, located between the first air guide plate 711 and the second air guide plate 712, and the left end of the second support plate 714 is connected to the second support plate 714.

[0146] It is understandable that the air duct housing 200 is formed by the first housing 250 and the second housing 260 being buckled and connected left and right. This can make the air duct housing 200 less difficult to manufacture during production, ensure that the air duct housing 200 can have a lower production cost, reduce the difficulty of assembling the air duct member, and reduce the difficulty of maintaining the (vertical) air conditioner indoor unit or air handling equipment with the air duct member during the later maintenance process.

[0147] Moreover, in this embodiment, due to the snap-fit ​​connection between the first shell 250 and the second shell 260, the left end / right end of the first air guide plate 340 cannot be connected to the air duct shell 200 in an integral manner. At this time, the air guide surface 715 may only include the top side surface of the first air guide plate 711, that is, the second air guide plate 712 is not provided. Specifically, the left end of the first air guide plate 711 is connected to the left inner wall of the first shell 250, and the right end of the first air guide plate 711 extends to contact the right inner wall of the second shell 260; or the right end of the first air guide plate 711 is connected to the right inner wall of the second shell 260, and the left end of the first air guide plate 711 extends to contact the left inner wall of the first shell 250. However, in the process of guiding the mixed airflow by the guide surface 715 of the first guide plate 711, the mixed airflow will generate a reaction force on the first guide plate 711. If the flow rate of the mixed airflow is too large, the first guide plate 711 may vibrate, causing the guiding effect of the first guide plate 711 on the mixed airflow to be greatly reduced, affecting the secondary air mixing effect of the mixed airflow and the heat exchange airflow. Therefore, the left and right widths of the first guide plate 711 can be set short, and the first support plate 713 can be added. This can avoid the possibility of the first guide plate 711 vibrating, ensure the guiding effect of the first guide plate 711 on the mixed airflow, and ensure the secondary air mixing effect of the mixed airflow and the heat exchange airflow. At the same time, a second guide plate 712 and a second support plate 714 are added, so that the guide surface occupies a larger proportion of the width of the first air outlet duct 212 in the left and right directions, further ensuring the guiding effect of the first guide plate 711 on the mixed airflow, and ensuring the secondary mixing effect of the mixed airflow and the heat exchange airflow.

[0148] In addition, the second air outlet duct 213 is also located between the first shell 250 and the second shell 260 .

[0149] Reference Fig. 20 In this embodiment, the number of the first guide plate 711 and the second guide plate 712 can be set to multiple. And the multiple first guide plates 711 are arranged between the first support plate 713 and the left inner wall of the first shell 250 in the vertical direction, and the multiple second guide plates 712 are arranged between the second support plate 714 and the right inner wall of the second shell 260 in the vertical direction. This further ensures the guiding effect of the first guide plate 711 and the second guide plate 712 on the mixed air flow, and ensures the secondary air mixing effect of the mixed air flow and the heat exchange air flow.

[0150] Reference Fig.12 , Fig.13 and Fig. 20 In this embodiment, the outlet end of the first air outlet duct 212 is disposed on the right side of the first vent 530, and the front end of the second support plate 714 is inclined to the left.

[0151] It is understandable that, since other components of the vertical air conditioner occupy the arrangement space between the air outlet of the fresh air mechanism 600 and the first vent 530, the first air outlet duct 212 as a whole can be arranged biased to the right side of the first vent 530, resulting in the outlet end of the first air outlet duct 212 being arranged biased to the right side of the first vent 530. At this time, in order to ensure that the mixed air flow flows forward / towards the front of the heat exchange air outlet 520, the front end of the second support plate 714 can be tilted to the left to ensure the secondary air mixing effect of the mixed air flow and the heat exchange air flow.

[0152] Reference Fig.14 , Fig.15 , Fig.16 and Fig.17 In the present embodiment, a second vent 540 is provided on the rear side of the shell 500; and, the air duct shell 200 extends backward to the second vent 540, and a second air outlet duct 213 is provided in the air duct shell 200, that is, the air duct cavity 210 includes a second air outlet duct 213, the air inlet end of the second air outlet duct 213 is connected to the fresh air mechanism 600, and the air outlet end of the second air outlet duct 213 is connected to the second vent 540, and the second air outlet duct 213 is used to transport the mixed air flow to the indoor space through the second vent 540.

[0153] It can be understood that, by providing the duct member including the first air outlet duct 212 and the second air outlet duct 213, the air conditioner indoor unit of this embodiment can deliver fresh air flow / mixed air flow forward and backward. Among them, by providing the second air outlet duct 213 and the second vent 540, the vertical air conditioner indoor unit of this embodiment can deliver the fresh air flow / mixed air flow backward to the indoor space, and then at this time, the fresh air flow / mixed air flow delivered to the indoor space will not blow to the user regardless of whether there is a temperature difference with the indoor ambient temperature, which greatly reduces the user's sense of temperature difference and further ensures the user's use experience.

[0154] Reference Fig.14 and Fig.15 In this embodiment, the heat exchange air inlet 510 is arranged on the rear side of the housing 500, and the second vent 540 is located below the heat exchange air inlet 510; and the vertical air conditioner indoor unit further includes a second air guide 720. The second air guide 720 is arranged at the second vent 540, and the second air guide 720 includes a third guide plate 721, and the third guide plate 721 is arranged obliquely upward along the direction of the mixed air flow.

[0155] It is understandable that, under the action of the third guide plate 721, the mixed air flow flowing out of the second vent 540 flows to the rear of the heat exchange air inlet 510, and the mixed air flow can pass through the indoor heat exchanger together with the indoor air flow to flow into the heat exchange air inlet 510. At this time, the air flow flowing out of the heat exchange air outlet 520 includes the fresh air flow, but the temperature of the fresh air flow can be consistent with the ambient temperature of the indoor space. The fresh air function of the mixed air flow flowing out of the first vent 530 can greatly eliminate the temperature difference between the fresh air flow and the indoor air flow, reduce the user's discomfort caused by the inconsistency between the outdoor fresh air flow and the ambient temperature of the indoor space, and greatly improve the user's experience.

[0156] In addition, the second air guide 720 may be a second air mixing outlet grille disposed at the second vent 540 .

[0157] In this embodiment, the air guide body 300 can be configured to the second state. At this time, the air flow rate flowing from the fresh air mechanism 600 into the second air outlet duct 213 is at a maximum value and the air flow rate flowing from the fresh air mechanism 600 into the first air outlet duct 212 is at a minimum value. The flow rate of the mixed air flow delivered forward by the vertical air-conditioning indoor unit is the minimum, and the flow rate of the mixed air flow delivered backward by the vertical air-conditioning indoor unit is the maximum. This can further reduce the user's discomfort caused by the inconsistency between the outdoor fresh air flow and the ambient temperature of the indoor space, thereby greatly improving the user experience.

[0158] In this embodiment, the vertical air conditioner indoor unit may include the filter sterilization component 100 in the above embodiment. Therefore, the vertical air conditioner indoor unit in this embodiment also has the beneficial technical effects of the filter sterilization component 100 in the above embodiment.

[0159] Reference Figure 2 , Fig. 22 In this embodiment, the filter sterilization component 100 is disposed in the fresh air mechanism 600, and the filter sterilization component 100 can be used to filter and sterilize the fresh air flow flowing into the fresh air mechanism 600, so as to ensure the cleanliness and low bacteria level of the fresh air flow, ensure the physical and mental health of the user, and ensure the user experience.

[0160] In this embodiment, the filtering and sterilizing component 100 is used to filter and sterilize the indoor airflow flowing into the fresh air mechanism 600, so as to ensure the cleanliness and low bacteria level of the indoor airflow, ensure the physical and mental health of the user, and ensure the user experience.

[0161] Reference Figure 2 , Fig.16 and Fig.17In this embodiment, the fresh air mechanism 600 includes a fresh air duct 610 and a centrifugal fan 620. The air inlet end of the fresh air duct 610 is connected to the outdoor space, so that the fresh air mechanism 600 can introduce the fresh air flow from the outdoor space into it; the centrifugal fan 620 is arranged in the housing 500, the air inlet 621 of the centrifugal fan 620 is connected to the air outlet end of the fresh air duct 610 and the first circulation air outlet 550, and the air outlet 622 of the centrifugal fan 620 is connected to the air inlet end (first air outlet 230) of the first air outlet duct 212 and the air inlet end (second air outlet 240) of the second air outlet duct 213, so as to realize the connection between the first air outlet duct 212 and the fresh air mechanism 600, and the connection between the second air outlet duct 213 and the fresh air mechanism 600.

[0162] Reference Figure 2 , Fig.16 , Fig.17 , Fig.21 and Fig. 22 In this embodiment, the fresh air mechanism 600 further includes a connecting piece 630, which is disposed in the housing 500, connected to the fresh air duct 610 and the centrifugal fan 620, and a connecting air cavity 631 is disposed in the connecting piece 630, which is connected between the air outlet end of the fresh air duct 610 and the air inlet 621. A second circulation air port 632 is provided on the connecting piece 630, and the second circulation air port 632 is connected to the first circulation air port 550, so as to realize the connection between the fresh air mechanism 600 and the first ventilation port 530.

[0163] It is understandable that the connection between the fresh air duct 610 and the centrifugal fan 620 can be facilitated by the arrangement of the connecting piece 630. Specifically, a fresh air port 633 is provided on the connecting piece 630, and the fresh air duct 610 is connected to the connecting air cavity 631 through the fresh air port 633. In addition, the connecting air cavity 631 can provide a configuration space for the filtration and sterilization assembly 100.

[0164] In addition, the location where the indoor airflow and the fresh air flow are mixed once in the fresh air mechanism 600 may be in the connecting air cavity 631 and / or in the centrifugal fan 620 .

[0165] Reference Fig.17 and Fig. 22 In this embodiment, the filtering and sterilizing component 100 is arranged in the connecting air cavity 631, and the filtering and sterilizing component 100 is located between the second circulating air outlet 632 and the air inlet 621 and between the fresh air outlet 633 and the air inlet 621, so that the filtering and sterilizing component 100 can filter and sterilize the fresh air flow and indoor air flow flowing into the fresh air mechanism 600.

[0166] Specifically, when the filtration and sterilization assembly 100 is arranged in the connecting air cavity 631, the first sterilization layer 123 of the sterilization cotton 120 can be arranged toward the second circulation air port 632 and the fresh air port 633. Alternatively, the second sterilization layer 124 of the sterilization cotton 120 can also be arranged toward the second circulation air port 632 and the fresh air port 633.

[0167] Reference Figure 2 , Fig.14 , Fig.16 , Fig.17 and Fig.23 In the present embodiment, since the fresh air duct 610 is extended in the front-to-back direction, the fresh air outlet 633 and the second circulation air outlet 632 are located behind the air inlet 621 to ensure the smoothness of the fresh air flow from the fresh air duct 610 into the fresh air mechanism 600; and, a first disassembly port 560 is provided on the side of the outer shell 500 at a position corresponding to the first filter bracket 130 of the filter sterilization component 100, and a second disassembly port 634 is provided on the connecting piece 630 at a position corresponding to the first filter bracket 130. The first disassembly port 560 and the second disassembly port 634 are used to allow the filter sterilization component 100 to be loaded into the connecting air cavity 631 from the outside of the outer shell 500 and to be disassembled from the connecting air cavity 631 to the outside of the outer shell 500.

[0168] It is understandable that the filter and sterilization assembly 100 can be replaced on the indoor unit of the vertical air conditioner by replacing the handle 134, the first disassembly opening 560 and the second disassembly opening 634.

[0169] Reference Figure 2 and Fig. 22 In this embodiment, the fresh air mechanism 600 further includes a grille stopper 650 disposed between the connecting member 630 and the air inlet 621 of the centrifugal fan 620. The grille stopper 650 cooperates with the connecting member 630 to promote the connecting air cavity 631 to form a relatively closed space, thereby ensuring the configuration of the filter sterilization component in the connecting air cavity 631.

[0170] Reference Fig.21 and Fig. 22 In this embodiment, the fresh air outlet 633 is adjacent to the second circulating air outlet 632; and the fresh air mechanism 600 further includes an adjusting plate 640. The adjusting plate 640 is movably arranged in the connecting air cavity 631 along the direction in which the fresh air outlet 633 and the second circulating air outlet 632 are relatively arranged. The adjusting plate 640 covers the fresh air outlet 633 and / or the second circulating air outlet 632. The adjusting plate 640 is used to adjust the air inlet area of ​​the fresh air outlet 633 and / or the second circulating air outlet 632 to adjust the flow rate of the fresh air flow and / or the indoor air flow flowing into the connecting air cavity 631.

[0171] It can be known that by setting the adjustment plate 640, the primary mixed air ratio of the fresh air flow and the indoor air flow can be adjusted to meet the user's requirements for the fresh air ratio in the indoor space and the heating speed / cooling speed of the vertical air-conditioning indoor mechanism, thereby ensuring the user experience.

[0172] Moreover, in the present embodiment, the adjustment plate 640 can be in a first position in which the fresh air outlet 633 is completely blocked and the air inlet area of ​​the second circulation air outlet 632 is maximized; it can also be in a second position in which the second circulation air outlet 632 is completely blocked and the air inlet area of ​​the fresh air outlet 633 is maximized; it can also be in a third position in which part of the fresh air outlet 633 is blocked and part of the second circulation air outlet 632 is blocked.

[0173] It should be understood that when the adjustment plate 640 is in the second position, the vertical air conditioner indoor unit can introduce the fresh air flow into the fresh air mechanism 600. At this time, the fresh air flow will no longer mix with the indoor air flow, but can be directly discharged to the front side of the heat exchange air outlet 520 and mix with the heat exchange air flow in the indoor space. To reduce the temperature difference between the fresh air flow and the indoor air flow. However, in this way of mixing air, there is still a temperature difference zone (cold air zone / warm air zone) after the fresh air flow flows out of the second vent 540 and before it mixes with the heat exchange air flow. In certain situations, such as taking something near the air conditioner, the user will still feel the temperature difference.

[0174] Furthermore, when the adjustment plate 640 is in the third position, the vertical air conditioner indoor unit will run the aforementioned double-mixed fresh air mode, that is, after the fresh air flow and the indoor air flow are mixed once in the fresh air mechanism 600, the formed mixed air flow will be mixed twice with the heat exchange air flow in the indoor space (in front of the heat exchange air outlet 520). Compared with the fresh air mode run by the vertical air conditioner indoor unit when the adjustment plate 640 is in the second position; or compared with the fresh air mode in which the fresh air flow and the heat exchange air flow are only mixed once indoors, the double-mixed fresh air mode will greatly reduce the discomfort caused to the user by the temperature difference zone, and greatly ensure the user experience of using the vertical air conditioner indoor unit.

[0175] Reference Fig.14 and Fig.15 In this embodiment, the vertical air conditioner indoor unit further includes an indoor circulation air inlet grille 820, and the indoor circulation air inlet grille 820 is disposed at the first circulation air outlet 550. The first circulation air outlet 550 is disposed on the rear side of the housing 500, and the first circulation air outlet 550 is disposed below the heat exchange air inlet 510.

[0176] Since the space at the rear bottom of the vertical air conditioner indoor unit is narrow and the indoor air volume is small, a fourth guide plate 821 is provided on the indoor circulation air inlet grille 820. The fourth guide plate 821 is arranged upwardly and tilted from front to rear to guide the indoor air flow in the upper space at the rear side of the vertical air conditioner indoor unit to flow into the housing 500. This ensures the inflow of air flow and ensures the operation of the vertical air conditioner in the mixed air fresh air mode.

[0177] In addition, the indoor circulation air inlet grille 820 and the second air mixing outlet grille can be an integrated structure.

[0178] Reference Fig.14 , Fig.15 , Fig.16 and Fig.17 In this embodiment, the second circulation air outlet 632 and the first circulation air outlet 550 may be connected without constructing an air duct. After the indoor air flow enters the housing 500, it flows to the second circulation air outlet 632 in the space where the fresh air mechanism 600 is arranged, and then enters the connecting air cavity 631.

[0179] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention.
