[0057] Unless otherwise defined, all terms (including technical terms and scientific terms) used in the description of this embodiment have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0058] In the description of this embodiment, reference to terms such as "this embodiment," "some embodiments," or "implementation methods" means that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0059] The following combination Figures 1 to 3 The filtration and sterilization component of this embodiment is described in detail. Figure 1 This is a schematic structural diagram of the sterilizing cotton in the filter sterilization assembly according to one embodiment of the present utility model; Figure 2 This is an exploded schematic diagram of a fresh air mechanism in a vertical air conditioner indoor unit according to one embodiment of the present utility model; Figure 3 It is along Figure 2 Enlarged diagram of point "A" in the figure.

[0060] In the prior art, air handling equipment processes the air in the indoor space. And in the process of processing the air, the step of filtering the air is involved, and thus, these devices are equipped with filter assemblies. At present, some forms of filter assemblies are to configure a filter screen / filter element on the filter bracket, and to configure a piece of black sterilization cotton on the front side / back side of the filter screen / filter element. This type of filter assembly is generally configured at the air inlet / fresh air module of the air conditioner (such as a wall-mounted air conditioner indoor unit, a vertical air conditioner indoor unit) to filter and sterilize the indoor air / fresh air flow that needs to be heat exchanged. However, when this type of filter assembly assembles the sterilization cotton onto the filter screen / filter element, it needs to be achieved through adhesives / fittings. When replacing the filter screen, filter element or sterilization cotton, it is necessary to laboriously disassemble the sterilization cotton and clean the adhesives / fittings, and the probability of the sterilization cotton being damaged is very high. This greatly reduces the replaceability of the sterilizing cotton and the convenience of replacing the filter screen, filter element or sterilizing cotton of the filter component.

[0061] Reference Figure 1 、 Figure 2 In this embodiment, the filter sterilization assembly 100 includes a filter 110 and sterilizing cotton 120. The filter 110 is used to filter the airflow flowing through it; the sterilizing cotton 120 is used to sterilize the airflow flowing through it. The sterilizing cotton 120 is provided with a receiving cavity 121, and the sterilizing cotton 120 is provided with a replacement port 122 connected to the receiving cavity 121. The filter 110 is provided in the receiving cavity 121. The replacement port 122 is used to allow the filter 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 110 to be removed from the receiving cavity 121 to the outside of the sterilizing cotton 120.

[0062] The sterilizing filter assembly 100 of this embodiment includes sterilizing cotton 120, which is provided with a cavity 121 for accommodating the filter 110. Furthermore, the sterilizing cotton 120 is provided with a replacement port 122 connected to the cavity 121. In other words, the sterilizing cotton 120 is pocket-shaped. Therefore, when replacing the sterilizing cotton 120 or the filter 110, the user or maintenance personnel can directly insert the filter 110 from the outside of the sterilizing cotton 120 into the cavity 121 through the replacement port 122, without the need to secure the sterilizing cotton 120 and the filter 110 to each other. Alternatively, when directly removing the filter 110 from the cavity 121 through the replacement port 122, there is no need to clean the adhesive, effectively preventing damage to the sterilizing cotton 120. Therefore, the sterilizing filter assembly 100 of this embodiment ensures the replaceability of the sterilizing cotton 120 and the convenience of replacing the filter 110 or the sterilizing cotton 120.

[0063] 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 assembly, the sterilizing effect on the airflow is poor. 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. In addition, 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 guarantee.

[0064] 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.

[0065] It is understood that since the sterilizing cotton 120 has a pocket-like structure with a receiving cavity 121 and a replacement port 122, that is, the sterilizing cotton 120 is wrapped around the filter 110, such a filter sterilization assembly 100 can include at least a first sterilizing layer 123 located on the front side of the filter 110 and a second sterilizing layer 124 located on the rear side of the filter 110. Therefore, during the process of replacing the filter 110 / sterilizing cotton 120 in the filter sterilization assembly 100 of this embodiment, the filter 110 can be directly loaded with the sterilizing cotton 120 or the sterilizing cotton 120 can be removed from the filter 110. While ensuring that the airflow can be sterilized at least twice, the filter 110 / sterilizing cotton 120 can be replaced in one go, making the replacement process very convenient. Furthermore, the replaceability of the filter 110 / sterilizing cotton 120 can be well ensured.

[0066] 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.

[0067] It is understood that since the filter 110 is in a plate or paper shape, positioning the replacement port 122 at the left, right, top, or bottom end of the sterilizing cotton pad 120 allows the filter 110 to be smoothly inserted into or removed from the sterilizing cotton pad 120. Furthermore, if the replacement port 122 were positioned at the front or rear side of the sterilizing cotton pad 120, airflow could pass through the replacement port 122 through the sterilizing cotton pad 120, significantly reducing the sterilization effect. Therefore, the present sterilizing cotton pad 120 can still achieve excellent sterilization effectiveness.

[0068] In this embodiment, the filter body 110 may be a filter screen.

[0069] Reference Figure 1 、 Figure 2 and Figure 3 In this embodiment, the filter body 110 is a filter element, which has a filter surface 111 located behind the first sterilization layer 123, and the filter surface 111 is wavy.

[0070] It is understandable that setting the filter surface 111 to be wavy can well ensure the effective filter surface area 111 of the filter surface 111, so as to ensure the sterilization effect of the filter element / filter sterilization component 100.

[0071] 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 .

[0072] It is understandable that by setting up the aromatherapy material, the air in the indoor space where the air treatment equipment is working 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 and 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 after 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 replenish the indoor space. Therefore, if the air conditioner is running for a long time, the air in the indoor space will be unacceptable to the user. Furthermore, the air flow through the filter and sterilization component 100 with the aromatherapy material attached can carry the odor molecules of the aromatherapy material into the indoor space to cover the original smell of the indoor space, thereby ensuring the user experience.

[0073] In this embodiment, the aromatherapy material is located at the bottom of the wave structure of the filter surface 111 .

[0074] 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 wavy 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.

[0075] Reference Figure 1 、 Figure 2In this embodiment, the filter sterilization assembly 100 includes a first filter support 130 and a second filter support 140. The first filter support 130 is provided with a filter cavity 131, and a first through hole 132 communicating with the filter cavity 131 is defined on the rear side of the first filter support 130. A placement opening 133 communicating with the filter cavity 131 is defined on the front side of the first filter support 130. The sterilizing cotton 120 is disposed in the filter cavity 131, and the first sterilizing layer 123 is disposed toward the placement opening 133. The second filter support 140 is detachably disposed at the placement opening 133, and a second through hole 141 communicating with the filter cavity 131 is defined on the second filter support 140.

[0076] It can be understood that by setting the first filter bracket 130 and the second filter bracket 140, the stability of the assembly of the filter body 110 and the sterilization cotton 120 can be guaranteed, while the convenience and assembly stability of the filter sterilization component 100 when assembled into the air treatment equipment can be guaranteed.

[0077] 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.

[0078] The following combination 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 component according to one embodiment of the present utility model; Figure 5 yes Figure 4 An enlarged schematic diagram of point "B" in the middle; Figure 6 This is a partial structural diagram of an air duct shell in an air duct member according to one embodiment of the present utility model; Figure 7 This is one of the structural schematic diagrams of the second shell of the air duct member according to one embodiment of the present utility model; Figure 8 yes Figure 7 An enlarged schematic diagram of the “C” in the middle; Figure 9 This is a second structural diagram of the second shell of the air duct component according to one embodiment of the present utility model; Figure 10 This is a third structural diagram of the second shell of the air duct member according to an embodiment of the present invention, wherein Figure 10 The dotted box in the figure represents two rotation positions / rotation states of the air guide body; Figure 11 It is a structural schematic diagram of an air guide body in an air duct member according to one embodiment of the utility model.

[0079] Reference Figure 4 and Figure 5In this embodiment, the air duct component of the air-conditioning indoor unit includes an air duct shell 200, and an air duct cavity 210 is provided in the air duct shell 200. The air duct cavity 210 is used to transport the outlet air flow to the indoor space where the air-conditioning indoor unit is located through the air outlet portion of the air-conditioning indoor unit, and the inner wall surface of the air duct cavity 210 is recessed to provide at least one soft air cavity 211. The soft air cavity 211 is used to guide the outlet air flow to flow therethrough to slow down the flow rate of the outlet air flow out of the air outlet portion.

[0080] Because the inner wall surface of the duct cavity 210 of the duct housing 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 airflow therethrough, thereby slowing the flow rate of the outlet airflow out of the air outlet portion. Therefore, the air duct member of the air conditioner indoor unit of this embodiment can soften the outlet airflow of the vertical air conditioner indoor unit, the air conditioner indoor unit, and its air duct member, so that when the outlet airflow blows towards the user, the user does not feel the airflow is too hard, thus ensuring the user experience of the vertical air conditioner indoor unit and the air conditioner indoor unit.

[0081] It should be noted that the air outlet may be the first vent 530 and / or the second vent 540 in the following embodiments.

[0082] In some embodiments, the shape of the soft wind chamber 211 may be rectangular.

[0083] In other embodiments, the cavity wall of the soft wind cavity 211 may be an irregular concave-convex surface.

[0084] 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 into the duct cavity 210. Alternatively, if the cavity wall of the soft wind cavity 211 is irregular, the outlet airflow will easily become 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, and the purification performance of the purifier.

[0085] Reference Figure 4 、 Figure 5 and Figure 6 In this 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 regularize the flow path of the outgoing air flow in the soft wind cavity 211.

[0086] 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 smooth. 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. After the outlet airflow enters the soft wind chamber 211, a regular gas vortex will be generated in the soft wind chamber 211. Following the flow of the vortex and the flow of the outlet airflow in the air duct chamber 210, the outlet airflow will flow smoothly back into the air duct chamber 210. Furthermore, setting the cavity wall surface of the soft wind cavity 211 to a spherical surface can greatly reduce or even eliminate the wind loss of the outlet air flow when flowing through the soft wind cavity 211, so as to ensure the working performance of the air treatment equipment.

[0087] 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.

[0088] It should be understood that the depth of the soft wind chamber 211 can determine the length of time the outlet airflow flows within the soft wind chamber 211, and as the depth of the soft wind chamber 211 increases, the length of time the outlet airflow flows within the soft wind chamber 211 increases. If the outlet airflow flows within the soft wind chamber 211 for a long time, it may cause significant wind loss in the outlet airflow within the soft wind chamber 211. If the outlet airflow flows within the soft wind chamber 211 for a short time, the soft wind chamber 211 may not be able to soften the outlet airflow.

[0089] Therefore, the depth of the soft air chamber 211 is set to a range of 0.25 mm to 0.35 mm. This ensures that the soft air chamber 211 has an appropriate depth and a suitable flow time in the soft air chamber 211, thereby effectively ensuring the softening effect of the soft air chamber 211 on the outgoing air flow and greatly reducing wind loss of the outgoing air flow.

[0090] 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.

[0091] It is understood that setting the angle between the tangent line at any point where the cavity wall and the inner wall meet to 9 to 11 degrees can effectively avoid a large angle between the inner wall of the soft wind cavity 211 and the inner wall of the air duct cavity 210, and ensure that the outlet airflow has a relatively suitable flow time in the soft wind cavity 211. This ensures the softening effect of the soft wind cavity 211 and avoids wind loss of the outlet airflow in the soft wind cavity 211.

[0092] Reference Figure 4 and Figure 5 In this embodiment, the number of the soft air chambers 211 is set to be multiple, and the multiple soft air chambers 211 are arranged adjacent to each other to ensure the overall performance of the air duct member in softening the outgoing air flow.

[0093] 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 entirety of the adjacent multiple soft wind cavities 211 is honeycomb-shaped.

[0094] 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 multiple times by the honeycomb structure, 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.

[0095] Reference Figure 4 In this embodiment, the air duct shell 200 is provided with an air duct inlet 220 connected to the air duct cavity 210 . The air duct cavity 210 includes multiple air outlet ducts connected to the air duct inlet 220 . The multiple air outlet ducts are connected at the air duct inlet 220 .

[0096] It is understandable 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 multiple components / directions of the air handling equipment (eg, a vertical air conditioner indoor unit).

[0097] Reference Figure 7 、 Figure 9 and Figure 10 In this embodiment, the air duct shell 200 is provided with an air duct inlet 220 connected to the air duct cavity 210. The air duct cavity 210 includes a first air outlet duct 212 and a second air outlet duct 213 connected to the air duct inlet 220. The first air outlet duct 212 and the second air outlet duct 213 are connected at the air duct inlet 220.

[0098] 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).

[0099] Reference Figure 7 、 Figure 9 and Figure 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. This allows the duct member of this embodiment to deliver air in opposite directions, or to deliver air to two oppositely disposed components of an air handling device (e.g., a floor-standing air conditioner indoor unit).

[0100] However, due to the large angles between the multiple outlet ducts, the airflow from the fan must change direction significantly as it flows through the multiple outlet ducts. This is especially true when the duct structure delivers air in opposite directions. The airflow is prone to impact and form vortices at the intersection of the fan and the multiple outlet ducts. This reduces the airflow efficiency of the duct structure and affects the performance of the air handling equipment with this duct structure. Furthermore, due to the fixed shape of the intersection, the flow rate of the airflow from the fan to each outlet duct is fixed, which cannot meet the user's demand for changes in airflow in any direction, greatly reducing the user experience.

[0101] Reference Figure 7 、 Figure 9 and Figure 10 In 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 arranged in the air duct cavity 210, and the air guide body 300 is arranged 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. The connecting end 330 is rotatably arranged 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.

[0102] The duct member of the air conditioner indoor unit of the present invention includes an air guide body 300 disposed within the duct cavity 210 thereof. Specifically, the air guide body 300 is disposed corresponding to the duct inlet 220 and is located between the first air outlet duct 212 and the second air outlet duct 213 of the duct cavity 210. Furthermore, the air guide body 300 has a first air guide slope 310 facing the duct inlet 220 and the first air outlet duct 212, a second air guide slope 320 facing the duct inlet 220 and the second air outlet duct 213, and a connecting end 330 facing the duct inlet 220. Consequently, the air guide body 300 can guide the airflow entering the duct cavity 210 from the duct inlet 220 toward the first air outlet duct 212 and the second air outlet duct 213, respectively, to suppress the generation of eddy currents. At the same time, the air guide 300 is rotatably disposed within the air duct cavity 210. Specifically, the connecting end 330 is rotatably disposed about the rotational axis of the air guide 300 toward the first air outlet duct 212 or the second air outlet duct 213. Thus, the air guide 300 can adjust the flow rate of air entering the first air outlet duct 212 and the second air outlet duct 213. Therefore, the present invention can ensure the air outlet efficiency and operating performance of the air duct member and the (vertical) air conditioner indoor unit. At the same time, the air duct member and the (vertical) air conditioner indoor unit can meet the user's demand for variable airflow in either direction, thereby ensuring a better user experience.

[0103] Reference Figure 7 、 Figure 9 and Figure 10 In this 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 rearward, 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.

[0104] 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. This allows the air guiding body 300 to guide the airflow entering the air duct cavity 210 from the air duct inlet 220 toward the first air outlet duct 212 and the second air outlet duct 213, respectively, while preventing the airflow entering the air duct cavity 210 from the air duct inlet 220 from flowing toward the first air outlet duct 212 and the second air outlet duct 213 due to an excessively large 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.

[0105] Furthermore, the air guide 300 can have a first state in which the airflow rate into the first air outlet duct 212 is adjusted to a maximum value and the airflow rate into the second air outlet duct 213 is adjusted to a minimum value. In this state, the connection end 330 rotates to a maximum angle about the rotation center axis of the air guide 300 toward the second air outlet duct 213. Furthermore, the air guide 300 can have a second state in which the airflow rate into the second air outlet duct 213 is adjusted to a maximum value and the airflow rate into the first air outlet duct 212 is adjusted to a minimum value. In this state, the connection end 330 rotates to a maximum angle about the rotation center axis of the air guide 300 toward the first air outlet duct 212. Furthermore, the maximum angle that the connecting end 330 can rotate about the rotational 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 that the connecting end 330 can rotate about the rotational 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 act on the airflow toward the first air outlet duct 212 and the second air outlet duct 213, thereby ensuring the normal operation of the air duct component. 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.

[0106] Reference Figure 11In 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 is arranged at a predetermined angle to the first air guide plate 340. 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.

[0107] It is understandable that the value of the preset angle may be the same as the value of the angle between the first wind guiding inclined surface 310 and the second wind guiding inclined surface 320 .

[0108] Reference Figure 11 In this 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.

[0109] It can be understood that the weight-reducing cavity 341 and its semi-closed configuration can ensure that the air guide body 300 can guide the airflow to the first air outlet duct 212 and the second air outlet duct 213 respectively and adjust the flow rate of the airflow to the first air outlet duct 212 and the second air outlet duct 213 respectively, while also ensuring the smoothness of the rotation of the air guide body 300 in the air duct cavity 210.

[0110] Reference Figure 4 and Figure 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.

[0111] Reference Figure 4 and Figure 11In this embodiment, the air guide 300 further includes a rotating shaft 380 and a connecting shaft 390. The rotating shaft 380 is connected to the top of the second connecting plate 370 and is rotatably connected to the air duct housing 200. The connecting shaft 390 is connected to the top of the first connecting plate 360 ​​and is arranged colinearly with the rotating shaft 380. Furthermore, the driving device 400 includes a driving motor 410. The driving motor 410 is arranged outside the air duct housing 200. The driving shaft of the driving motor 410 passes through the air duct housing 200 and is connected to the air guide 300. The driving shaft and the connecting shaft 390 are arranged colinearly. This realizes the configuration of electrically driving the air guide 300.

[0112] Reference Figure 7 、 Figure 9 and Figure 10 In this embodiment, the air duct housing 200 is provided with a first air outlet 230 and a second air outlet 240. The air duct inlet 220 is located between the first air outlet 230 and the second air outlet 240. The first air outlet duct 212 and the second air outlet duct 213 extend from the air duct inlet 220 in opposite directions and are connected to the first air outlet 230 and the second air outlet 240, respectively. This enables the air duct member to transport air in two opposite directions.

[0113] Reference Figure 7 、 Figure 9 and Figure 10 In this embodiment, the width I of the portion of the first air outlet duct 212 close to the first air outlet 230 in the up-down direction is greater than the width J of the portion of the first air outlet duct 212 close to the air duct inlet 220 in the up-down direction; and the width K of the portion of the second air outlet duct 213 close to the second air outlet 240 in the up-down direction is greater than the width L of the portion of the second air outlet duct 213 close to the air duct inlet 220 in the up-down direction.

[0114] It can be understood that setting the first air outlet duct 212 and the second air outlet duct 213 to be trumpet-shaped, or setting the duct member to be double trumpet-shaped, can effectively ensure the air supply efficiency of the duct member and ensure the air outlet / working performance of the (vertical) air-conditioning indoor unit (or air handling equipment).

[0115] The air conditioner indoor unit of this embodiment will be described in detail below.

[0116] In this embodiment, the air conditioner indoor unit includes the duct member and / or the filter sterilization assembly 100 of the above embodiment. Furthermore, the air conditioner indoor unit of the present invention also has the beneficial technical effects of the duct member and / or the filter sterilization assembly 100.

[0117] The following combination Figure 2 、 Figures 7 to 10 as well as Figures 12 to 23The vertical air-conditioning indoor unit of this embodiment will be described in detail. Figure 12 This is one of the structural diagrams of a vertical air-conditioning indoor unit according to one embodiment of the present utility model; Figure 13 yes Figure 12 An enlarged schematic diagram of the point "D" in the middle; Figure 14 This is a second structural diagram of a vertical air-conditioning indoor unit according to an embodiment of the present utility model; Figure 15 yes Figure 14 An enlarged schematic diagram of the “E” in the middle; Figure 16 This is one of the internal structural diagrams of a vertical air-conditioning indoor unit according to one embodiment of the present utility model; Figure 17 yes Figure 16 An enlarged schematic diagram of the "F" in the middle; Figure 18 1 is a schematic diagram of the flow paths of the mixed airflow, indoor airflow, and fresh airflow in a vertical air conditioner indoor unit according to one embodiment of the present invention, wherein the dotted arrows in the figure represent the flow path of the fresh airflow, the solid straight arrows in the figure represent the flow path of the mixed airflow, the hollow arrows in the figure represent the flow path of the indoor airflow, and the solid arrows in the figure represent the flow path of the heat exchange airflow; Figure 19 This is a third structural diagram of a vertical air-conditioning indoor unit according to an embodiment of the present invention; Figure 20 This is a second structural diagram of an air duct component according to an embodiment of the present utility model; Figure 21 This is a structural diagram of a connecting piece in a vertical air-conditioning indoor unit according to one embodiment of the present utility model; Figure 22 It is a cross-sectional schematic diagram of a connecting piece in a vertical air-conditioning indoor unit according to one embodiment of the present utility model; Figure 23 This is a second schematic diagram of the internal structure of a vertical air-conditioning indoor unit according to an embodiment of the present utility model.

[0118] In this embodiment, the vertical air conditioner indoor unit includes a housing 500 and the air duct member of the above embodiment. Furthermore, the vertical air conditioner indoor unit of the present invention also has the beneficial technical effects of the above air duct member.

[0119] Reference Figure 12 、 Figure 14 and Figure 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. In addition, 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. The indoor heat exchanger is arranged in the heat exchange air duct, and then the heat exchange air outlet 520 can flow out the heat exchange air flow that has passed through the indoor heat exchanger of the vertical air conditioner indoor unit.

[0120] 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 force the indoor airflow through the heat exchange inlet 510 into the heat exchange duct. After the indoor airflow exchanges heat with the indoor heat exchanger, it forms a heat exchange airflow, i.e., a cooling airflow. The cooling airflow is blown into the indoor space through the heat exchange outlet 520, thereby achieving a cooling mode. When the indoor heat exchanger is configured as a condenser, the vertical air conditioner indoor unit of this embodiment can force the indoor airflow through the heat exchange inlet 510 into the heat exchange duct. After the indoor airflow exchanges heat with the indoor heat exchanger, it forms a heat exchange airflow, i.e., a heating airflow. The heating airflow is blown into the indoor space through the heat exchange outlet 520, thereby achieving a heating mode. When the indoor heat exchanger is not operating, the vertical air conditioner indoor unit of this embodiment can simply blow air into the room, thereby achieving a ventilation mode that neither cools nor heats the room.

[0121] Reference Figure 12 、 Figure 13 、 Figure 16 and Figure 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 disposed within the housing 500, connected to the first vent 530 and the outdoor space, and is used to introduce fresh air from the outdoor space into the indoor unit; and the air duct housing 200 is disposed within the housing 500, the air inlet end (air duct 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 in the fresh air mechanism 600 forward through the first vent 530 to the indoor space.

[0122] It is understood that the vertical air conditioner indoor unit of this embodiment can transport fresh air from the outdoor space forward into the indoor space through the provision of the fresh air mechanism 600, thereby ensuring the user's physical and mental health and improving the user experience. The user can also feel the fresh air blowing in their face, further improving the user experience.

[0123] Currently, with existing technologies, during most of the air conditioner's operation, there's a significant difference between the indoor and outdoor ambient temperatures. For example, in winter, when the air conditioner is operating in cooling mode, or in summer, when the air conditioner is operating in heating mode. This creates a significant temperature difference between the fresh air delivered into the room by the fresh air module and the indoor ambient temperature, causing significant discomfort to the user and reducing their experience.

[0124] Reference Figure 14 、 Figure 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.

[0125] It is understood 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 reducing user discomfort caused by the mismatch between the outdoor fresh airflow and the indoor ambient temperature. As a result, the vertical air conditioner indoor unit of this embodiment can effectively improve the user experience.

[0126] However, the mixed air flow formed by mixing the fresh air flow with the indoor air flow in the fresh air mechanism 600, after being blown out of the shell 500 and into the indoor space, still has a certain difference with the indoor temperature, which may still cause a temperature difference sensation to the human body.

[0127] Figure 7 、 Figure 8 、 Figure 9 and Figure 10 In this embodiment, a first air outlet duct 212 is provided in the air duct shell 200 (that is, 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. The 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 outlet 520 and mix with the heat exchange air flow.

[0128] Reference Figure 18 The vertical air conditioner indoor unit of this embodiment includes a fresh air mechanism 600 and an air duct housing 200. The fresh air mechanism 600 can mix the fresh air flow with the indoor air flow before delivering it to the indoor space, thereby reducing the temperature difference between the fresh air flow and the ambient temperature of the indoor space. Furthermore, an air guide surface 715 is provided within the first air outlet duct 212 and / or at the first vent 530. The outlet end of the air guide surface 715 is inclined toward the first vent 530. The air guide surface 715 can then direct the mixed air flow formed by the primary mixing toward the front of the heat exchange outlet 520 for secondary mixing with the heat exchange air flow. This secondary mixing is then delivered to the indoor space, further reducing the temperature difference between the fresh air flow and the ambient temperature of the indoor space. This significantly reduces the user discomfort caused by the temperature difference zones described in the following embodiments. Therefore, the vertical air conditioner indoor unit of this embodiment can significantly enhance the user experience.

[0129] Reference Figure 19 In this embodiment, the vertical air conditioning indoor unit further includes at least one first air mixing outlet grille 810 disposed at the first vent 530. The outlet holes on each first air mixing outlet grille 810 can have different shapes, for example, the outlet holes can be circular, triangular, or strip-shaped. Furthermore, the first air mixing outlet grille 810 can divide the mixed air flow from the first vent, so that the mixed air flow does not feel too hard on the user, softening the mixed air flow and ensuring a better user experience. Furthermore, multiple first air mixing outlet grilles 810 can be stacked at the first vent 530 to further soften the mixed air flow and ensure a better user experience.

[0130] 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 and obliquely from the back to the front. The air guide surface 715 includes the top side of the air induction plate.

[0131] Furthermore, the vertical air-conditioning indoor unit of this embodiment can guide the mixed air flow toward the front of the heat exchange air outlet 520 through the provision of the air guide plate to achieve secondary mixing with the heat exchange air flow.

[0132] In addition, the air induction plate may be a portion of the first air mixing and outlet grille 810 where no air outlet holes are provided.

[0133] In other embodiments, the first vent 530 is located below the heat exchange outlet 520 ; and the first air outlet duct 212 is arranged upwardly and tilted from back to front, and the air guide surface 715 includes the inner bottom wall of the first air outlet duct 212 .

[0134] Furthermore, the vertical air-conditioning indoor unit of this embodiment can guide the mixed airflow toward the front of the heat exchange air outlet 520 to be mixed with the heat exchange airflow for a second time by arranging the first air outlet duct 212 obliquely.

[0135] Reference Figure 8 and Figure 12 In this embodiment, the first ventilation port 530 is located below the heat exchange outlet 520; and the vertical air-conditioning indoor unit further includes a first air guide 710, which is arranged in the first air outlet duct 212, and the first air guide 710 is arranged close to the air outlet end of the first air outlet duct 212, and the first air guide 710 includes a first guide plate 711, which 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 includes the top side surface of the first guide plate 711.

[0136] Furthermore, the vertical air-conditioning indoor unit of this embodiment can guide the mixed air flow toward the front of the heat exchange air outlet 520 through the inclined arrangement of the first guide plate 711 to achieve secondary mixing with the heat exchange air flow.

[0137] In some other embodiments, the first vent 530 is located above, to the left, or to the right of the heat exchange outlet 520. Accordingly, the outlet end of the air guide surface 715 is directed downward, to the left, and / or to the right. Specifically, the air induction plate, the first air outlet duct 212, and / or the first guide plate 711 can be arranged at an angle to direct the mixed airflow toward the front of the heat exchange outlet 520 for secondary mixing with the heat exchange airflow.

[0138] For example, when the first vent 530 is set on the left side of the heat exchange air outlet, and the air duct plate is set vertically, and the air outlet end of the air duct 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 duct plate is set vertically, and the air outlet end of the air duct 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 duct plate is set horizontally, and the air outlet end of the air duct 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.

[0139] Reference Figure 8 In the first embodiment of the first deflector 711, the air duct housing 200 extends forward from the fresh air mechanism 600 to the first vent 530. The left and right ends of the first deflector 711 are respectively connected to the left and right inner walls of the first outlet duct 212. This allows the first deflector 711 to be disposed within the air duct cavity 210.

[0140] Reference Figure 8 In this embodiment, the number of the first guide plates 711 is set to be multiple, and the multiple first guide plates 711 are arranged in the up and down directions to ensure the guiding effect of the first guide plates 711 on the mixed air flow and ensure the secondary mixing effect of the mixed air flow and the heat exchange air flow.

[0141] Reference Figure 16 、 Figure 17 and Figure 20In the second embodiment of the first air guide plate 711, the air duct housing 200 extends forward from the fresh air mechanism 600 to the first vent 530. The air duct housing 200 includes a first shell 250 and a second shell 260 that are interlocked and connected. The first shell 250 is located to the left of the second shell 260, and the first air outlet duct 212 is located between the first shell 250 and the second shell 260. Furthermore, 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 toward the right inner wall of the second shell 260. The first air guide 710 also includes a second air guide plate 712, a first support plate 713, and a second support plate 714. The right end of the second air guide plate 712 is connected to the right inner wall of the second shell 260, and the left end of the second air guide plate 712 extends toward the left inner wall of the second shell 260. The second air guide plate 712 is arranged upwardly and obliquely along the direction of the mixed air flow in the first air outlet duct 212. 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 vertical direction, and the end of the first support plate 713 is connected to the top wall and / or 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 vertical direction, and the end of the second support plate 714 is connected to the top wall and / or 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.

[0142] It is understood that the duct housing 200 is formed by the left and right snap-fit ​​connection of the first shell 250 and the second shell 260. This can reduce the manufacturing difficulty of the duct housing 200, ensure that the duct housing 200 can have a lower production cost, reduce the difficulty of assembling the duct components, and reduce the maintenance difficulty of the (vertical) air conditioner indoor unit or air handling equipment equipped with the duct components during the subsequent maintenance process.

[0143] Furthermore, in this embodiment, due to the snap-fit ​​connection between the first housing 250 and the second housing 260, the left / right ends of the first air deflector 340 cannot be integrally connected to the air duct housing 200. In this case, the air deflector surface 715 may comprise only the top side surface of the first air deflector 711, i.e., the second air deflector 712 is not provided. Specifically, the left end of the first air deflector 711 is connected to the left inner wall of the first housing 250, and the right end of the first air deflector 711 extends and contacts the right inner wall of the second housing 260; or the right end of the first air deflector 711 is connected to the right inner wall of the second housing 260, and the left end of the first air deflector 711 extends and contacts the left inner wall of the first housing 250. However, when the guide surface 715 of the first guide plate 711 guides the mixed airflow, the mixed airflow will generate a reaction force on the first guide plate 711. If the velocity of the mixed airflow is too high, the first guide plate 711 may vibrate, significantly reducing its guiding effect on the mixed airflow and affecting the secondary air mixing effect between the mixed airflow and the heat exchange airflow. Therefore, the left and right widths of the first guide plate 711 can be shortened, and the first support plate 713 can be added. This can prevent the first guide plate 711 from vibrating, ensure the first guide plate 711's guiding effect on the mixed airflow, and ensure the secondary air mixing effect between 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 air flow, and ensuring the secondary mixing effect of the mixed air flow and the heat exchange air flow.

[0144] In addition, the second air outlet duct 213 is also located between the first shell 250 and the second shell 260 .

[0145] Reference Figure 20 In this embodiment, the number of first guide plates 711 and second guide plates 712 can be multiple. The multiple first guide plates 711 are vertically arranged between the first support plate 713 and the left inner wall of the first housing 250, while the multiple second guide plates 712 are vertically arranged between the second support plate 714 and the right inner wall of the second housing 260. This further ensures that the first guide plates 711 and second guide plates 712 guide the mixed airflow and the secondary air mixing effect between the mixed airflow and the heat exchange airflow is achieved.

[0146] Reference Figure 12 、 Figure 13 and Figure 20 In this embodiment, the outlet end of the first air outlet duct 212 is arranged on the right side of the first vent 530, and the front end of the second support plate 714 is arranged to be inclined to the left.

[0147] It is understandable that, because other components of the vertical air conditioner occupy the space between the outlet of the fresh air mechanism 600 and the first vent 530, the first air outlet duct 212 as a whole can be positioned offset to the right of the first vent 530, resulting in the outlet end of the first air outlet duct 212 being positioned offset to the right of the first vent 530. In this case, to ensure that the mixed airflow flows forward / toward the front of the heat exchange outlet 520, the front end of the second support plate 714 can be tilted to the left to ensure a secondary mixing effect between the mixed airflow and the heat exchange airflow.

[0148] Reference Figure 14 、 Figure 15 、 Figure 16 and Figure 17 In this embodiment, a second vent 540 is provided on the rear side of the shell 500; and the air duct shell 200 extends backward at 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 the 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 through the second vent 540 to the indoor space.

[0149] It is 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 / mixed air in a forward and backward direction. Specifically, 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 / mixed air backward into the indoor space. Furthermore, at this time, regardless of whether there is a temperature difference between the fresh air / mixed air delivered to the indoor space and the indoor ambient temperature, the fresh air / mixed air will not blow onto the user, thereby greatly reducing the user's sense of temperature difference and further ensuring the user's user experience.

[0150] Reference Figure 14 and Figure 15 In this embodiment, the heat exchange air inlet 510 is provided 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 provided at the second vent 540 and includes a third guide plate 721, which is arranged obliquely upward along the direction of the mixed air flow.

[0151] It is understood that, under the action of the third guide plate 721, the mixed airflow flowing out of the second vent 540 flows toward the rear of the heat exchange inlet 510, and the mixed airflow can pass through the indoor heat exchanger together with the indoor airflow that is about to flow into the heat exchange inlet 510. At this time, the airflow flowing out of the heat exchange outlet 520 includes fresh air, but the temperature of the fresh air can be consistent with the ambient temperature of the indoor space. Combined with the fresh air function of the mixed airflow flowing out of the first vent 530, it 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 indoor ambient temperature, and greatly improve the user experience.

[0152] In addition, the second air guide 720 may be a second air mixing grille provided at the second vent 540 .

[0153] 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 the maximum value and the air flow rate flowing from the fresh air mechanism 600 into the first air outlet duct 212 is at the 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.

[0154] In this embodiment, the vertical air conditioner indoor unit can include the filter sterilization assembly 100 in the above embodiment. Therefore, the beneficial technical effects of the filter sterilization assembly 100 in the above embodiment are also possessed by the vertical air conditioner indoor unit in this embodiment.

[0155] Reference Figure 2 、 Figure 22 In this embodiment, the filter sterilization assembly 100 is disposed within the fresh air mechanism 600 and can be used to filter and sterilize the fresh air flowing into the fresh air mechanism 600. This ensures that the fresh air is clean and low in bacteria, ensuring the user's physical and mental health and user experience.

[0156] In this embodiment, the filtration and sterilization assembly 100 is used to filter and sterilize the indoor air flowing into the fresh air mechanism 600 to ensure the cleanliness and low bacteria level of the indoor air, thereby ensuring the physical and mental health of the user and ensuring the user experience.

[0157] Reference Figure 2 、 Figure 16 and Figure 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, and 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 of the first air outlet duct 212 (the first air outlet 230) and the air inlet end of the second air outlet duct 213 (the second air outlet 240), so as to realize the communication between the first air outlet duct 212 and the fresh air mechanism 600, and the communication between the second air outlet duct 213 and the fresh air mechanism 600.

[0158] Reference Figure 2 、 Figure 16 、 Figure 17 、 Figure 21 and Figure 22 In this embodiment, the fresh air mechanism 600 further includes a connecting member 630 disposed within the housing 500. The connecting member 630 is connected to the fresh air duct 610 and the centrifugal fan 620. A connecting air cavity 631 is provided within the connecting member 630, connecting the air outlet of the fresh air duct 610 and the air inlet 621. Furthermore, a second circulating air port 632 is defined in the connecting member 630, which is connected to the first circulating air port 550, thereby establishing communication between the fresh air mechanism 600 and the first vent 530.

[0159] It is understood that the connection piece 630 facilitates communication between the fresh air duct 610 and the centrifugal fan 620. Specifically, the connection piece 630 is provided with a fresh air port 633, and the fresh air duct 610 is connected to the connecting air cavity 631 through the fresh air port 633. Furthermore, the connecting air cavity 631 provides space for the filtration and sterilization assembly 100.

[0160] In addition, the location where the indoor air flow 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 .

[0161] Reference Figure 17 and Figure 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.

[0162] Specifically, when the filtration and sterilization assembly 100 is placed in the ventilation cavity 631, the first sterilization layer 123 of the sterilization cotton 120 can be placed 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 placed toward the second circulation air port 632 and the fresh air port 633.

[0163] Reference Figure 2 、 Figure 14 、 Figure 16 、 Figure 17 and Figure 23 In this 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 and 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 and 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.

[0164] It is understandable that the filter and sterilization assembly 100 can be replaced on the vertical air conditioner indoor unit by replacing the handle 134, the first disassembly opening 560 and the second disassembly opening 634.

[0165] Reference Figure 2 and Figure 22 In this embodiment, the fresh air mechanism 600 further includes a grille block 650 disposed between the connecting member 630 and the air inlet 621 of the centrifugal fan 620. The grille block 650 cooperates with the connecting member 630 to form a relatively closed space in the connecting air cavity 631, thereby ensuring the placement of the filter and sterilization assembly within the connecting air cavity 631.

[0166] Reference Figure 21 and Figure 22 In this embodiment, the fresh air inlet 633 is adjacent to the second circulating air inlet 632; and the fresh air mechanism 600 further includes an adjustment plate 640. The adjustment plate 640 is movably disposed within the connecting air cavity 631 along the relative arrangement direction of the fresh air inlet 633 and the second circulating air inlet 632. The adjustment plate 640 covers the fresh air inlet 633 and / or the second circulating air inlet 632. The adjustment plate 640 is used to adjust the air inlet area of ​​the fresh air inlet 633 and / or the second circulating air inlet 632, thereby adjusting the flow rate of the fresh air and / or the indoor air flowing into the connecting air cavity 631.

[0167] It can be known that by setting the adjustment plate 640, the 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 user experience.

[0168] Moreover, in this 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 the largest; 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 the largest; 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.

[0169] It should be understood that when the adjustment plate 640 is in the second position, the vertical air-conditioning indoor unit can introduce the fresh air flow into the fresh air mechanism 600. At this time, the fresh air flow will no longer be mixed with the indoor air flow, but can be directly discharged into the front side of the heat exchange air outlet 520 and mixed with the heat exchange air flow in the indoor space. This is to reduce the temperature difference between the fresh air flow and the indoor air flow. However, with this air mixing method, 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 when taking something near the air conditioner, the user will still feel the temperature difference.

[0170] Furthermore, when the adjustment plate 640 is in the third position, the stand-alone air conditioner indoor unit operates in the aforementioned double-air mixing fresh air mode. That is, after the fresh air flow and the indoor air flow are mixed once within the fresh air mechanism 600, the resulting mixed air flow is mixed a second time with the heat exchange air flow in the indoor space (in front of the heat exchange air outlet 520). Compared to the fresh air mode operated when the adjustment plate 640 is in the second position, or compared to the fresh air mode in which the fresh air flow and the heat exchange air flow are only mixed once indoors, this double-air mixing fresh air mode significantly reduces user discomfort caused by temperature differences and greatly improves the user experience of the stand-alone air conditioner indoor unit.

[0171] Reference Figure 14 and Figure 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 inlet 550. The first circulation air inlet 550 is disposed on the rear side of the housing 500, and the first circulation air inlet 550 is disposed below the heat exchange air inlet 510.

[0172] Because the space at the rear bottom of the vertical air conditioner indoor unit is narrow and the amount of indoor air is low, a fourth deflector 821 is provided on the indoor circulating air inlet grille 820. The fourth deflector 821 is arranged upwardly and tilted from front to back to guide the indoor airflow from the upper space at the rear of the vertical air conditioner indoor unit into the housing 500. This ensures the inflow of air and enables the vertical air conditioner to operate in the mixed air fresh air mode.

[0173] In addition, the indoor circulation air inlet grille 820 and the second air mixing outlet grille can be an integrated structure.

[0174] Reference Figure 14 、 Figure 15 、 Figure 16 and Figure 17 In this embodiment, the second circulation air outlet 632 and the first circulation air outlet 550 do not need to be connected by an air duct. After the indoor air enters the housing 500, it flows through the space where the fresh air mechanism 600 is arranged to the second circulation air outlet 632 and then enters the connecting air cavity 631.

[0175] 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 consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention.
