Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, and in particular to a vertical air conditioning indoor unit. Background Technology

[0002] With the increasing demand for indoor air quality, floor-standing air conditioner indoor units are gradually integrating fresh air functions to achieve air circulation and pollutant filtration.

[0003] In existing technologies, in order to improve the efficiency of fresh air delivery and meet the needs of visualization, some designs place the fresh air outlet on the front side of the casing and adopt a double-sided fresh air outlet structure to increase the fresh air volume. However, when the fresh air is split into two fresh air outlets through a single fresh air channel, the fresh air flow will generate turbulence or impact due to differences in flow velocity or uneven paths, thereby generating noise and affecting the user experience. Utility Model Content

[0004] This application discloses a vertical air conditioner indoor unit that can improve noise and enhance user experience.

[0005] To achieve the above objectives, this application discloses a vertical air conditioner indoor unit, comprising:

[0006] The housing has an internal cavity and is provided with a fresh air inlet and a fresh air outlet.

[0007] A fresh air module, wherein the fresh air module is used to provide fresh air to the room, the fresh air module comprising:

[0008] The fresh air duct component is disposed in the receiving cavity. The fresh air duct component forms a first fresh air duct. The air inlet end of the first fresh air duct is connected to the fresh air inlet, and the air outlet end of the first fresh air duct is connected to the fresh air outlet.

[0009] The fresh air fan is installed inside the fresh air duct component. The fresh air fan is used to introduce fresh air into the first fresh air duct through the fresh air inlet and drive the fresh air to blow into the room through the fresh air outlet.

[0010] The fresh air outlet includes:

[0011] First fresh air outlet;

[0012] The second fresh air outlet is provided at a distance from the first fresh air outlet along the width direction of the housing;

[0013] The housing also contains:

[0014] Mounting base, the mounting base is connected to the air outlet end of the fresh air duct component, and a second fresh air duct is formed in the mounting base and communicates with the first fresh air duct. The second fresh air duct is also communicated with the first fresh air outlet and the second fresh air outlet respectively.

[0015] A partition plate is disposed on the mounting base and located within the second fresh air duct. The partition plate can divide the second fresh air duct into a first duct and a second duct. The first duct is connected to the first fresh air outlet, and the second duct is connected to the second fresh air outlet.

[0016] Because the partition can divide the second fresh air duct into a first duct and a second duct, with the first duct connected to the first fresh air outlet and the second duct connected to the second fresh air outlet, the fresh air flow in the first and second ducts is relatively more stable. Furthermore, the flow rate of the fresh air can be adjusted more precisely according to actual conditions. Compared to a scheme where the first and second fresh air outlets are each connected to a separate second fresh air duct, independent first and second ducts can reduce turbulence and impact at the outlet of the second fresh air duct, thereby effectively reducing wind noise, providing a quieter indoor environment, and ultimately improving the user experience.

[0017] In one possible implementation, the mounting base is detachably connected to the fresh air duct component.

[0018] The detachable connection to the fresh air duct component via the mounting bracket facilitates maintenance should the mounting bracket or the fresh air duct component be damaged.

[0019] In one possible implementation, the partition plate is located in the middle of the second fresh air duct in the width direction of the housing.

[0020] Therefore, by positioning the partition plate in the middle of the second fresh air duct in the width direction of the casing, the fresh airflow can be evenly distributed to the independent first and second air ducts, thereby ensuring that the fresh airflow is evenly delivered from the first and second fresh air outlets, which is beneficial to improving the uniformity of indoor air quality.

[0021] On the other hand, the partition in the middle allows the airflow path and resistance in the first and second air ducts to be roughly the same, which helps to balance the airflow pressure in the first and second air ducts, thereby reducing the risk of increased noise.

[0022] On the other hand, the partition being located in the middle helps to achieve a symmetrical design of the indoor unit of the vertical air conditioner, thereby enhancing the visual effect and quality of the product and meeting users' aesthetic needs for the product's appearance.

[0023] In one possible implementation, the partition plate is sealed to the inner wall of the housing on a first side away from the first fresh air duct.

[0024] Since the first side of the partition plate, which is away from the first fresh air duct, is sealed to the inner wall of the casing, on the one hand, it ensures that the fresh air flow can only be delivered through the independent first air duct and the corresponding first fresh air outlet, and the second fresh air outlet corresponding to the second air duct, thus avoiding air leakage at the connection between the partition plate and the inner wall of the casing.

[0025] On the other hand, the sealed connection allows the fresh air to flow stably in the first and second air ducts, preventing airflow disturbances, vortices, or backflows caused by the gap between the partition plate and the casing, thus further ensuring the quietness of the indoor space.

[0026] In one possible implementation, a flexible connecting portion is provided on the inner wall of the housing;

[0027] The first side of the partition plate abuts against the flexible connection portion to seal the partition plate against the housing.

[0028] Since the first side of the partition plate abuts against the flexible connection part to seal the partition plate with the housing, the flexible connection part can adaptively deform according to the installation position of the partition plate and the shape of the inner wall of the housing, and closely fit the first side of the partition plate. Even if there are certain manufacturing errors in the housing or minor deformation after installation, a good sealing effect can be guaranteed, effectively preventing fresh air leakage.

[0029] On the other hand, when the fresh air module is running, the casing or partition may undergo slight displacement due to factors such as vibration of the fresh air fan and temperature changes. The flexible connection part can compensate for these displacements through its own elastic deformation, maintain a sealed state, ensure that the fresh air flow follows the designed path, and improve the stability and reliability of the fresh air module.

[0030] On the other hand, because the flexible connection is elastic, it can absorb and buffer the vibration generated by the operation of the fresh air module to reduce the vibration amplitude of the casing. Therefore, the noise generated by vibration friction between the casing and the partition plate will also be reduced accordingly. At the same time, the flexible connection can also block the airflow noise in the duct from spreading outward, creating a quieter indoor environment.

[0031] In one possible implementation, the first side of the partition plate is flush with the end face of the second fresh air duct away from the first fresh air duct.

[0032] Since the first side of the partition plate is flush with the end face of the second fresh air duct away from the first fresh air duct, the flush design ensures that the ends of the independent first and second air ducts near the casing are on the same plane. This ensures that the flow conditions of the fresh air at the outlets of the first and second air ducts are basically the same, avoiding uneven airflow caused by differences in the flow conditions of the fresh air at the outlets of the first and second air ducts.

[0033] On the other hand, the flush design reduces the possibility of impurities accumulating in the gap between the partition plate and the end face of the casing, thus helping to maintain the cleanliness of the fresh air.

[0034] In one possible implementation, the partition plate is also sealed to the inner wall of the second fresh air duct.

[0035] The partition plate is also sealed to the inner wall of the second fresh air duct. On the one hand, it can effectively prevent the fresh air from leaking into the fresh air duct components, thereby avoiding the fresh air from mixing with other airflows (such as return airflow or outside airflow), which in turn improves the ventilation effect and air quality of the indoor space.

[0036] On the other hand, the sealed connection ensures that the fresh airflow can only flow out through the independently designed first and second air ducts, and is delivered in a predetermined proportion and direction, thereby improving the controllability and comfort of the fresh airflow.

[0037] On the other hand, it can make the flow of fresh air within the fresh air duct more stable and smooth, reducing the risk of noise, vibration and other phenomena caused by leakage or disturbance of fresh air flow.

[0038] In one possible implementation, the cross-sectional area of ​​the first fresh air duct is smaller than the cross-sectional area of ​​the second fresh air duct.

[0039] Since the cross-sectional area of ​​the first fresh air duct is smaller than that of the second fresh air duct, on the one hand, according to the principle of fluid continuity, under the condition of a certain fresh air flow rate, the larger cross-sectional area of ​​the second fresh air duct will slow down the flow rate of the fresh air at this point. Therefore, when the fresh air flows out of the second fresh air duct and enters the indoor space, it can diffuse at a lower speed, which is conducive to the design of the soft airflow at the fresh air outlet, thereby providing a more comfortable air environment for the people in the room.

[0040] On the other hand, since the cross-sectional area of ​​the second fresh air duct is larger than that of the first fresh air duct, and the air velocity of the fresh air in the second fresh air duct is lower than that in the first fresh air duct, the friction of the fresh air in the second fresh air duct and the inner wall of the fresh air duct component is reduced, thereby effectively reducing wind noise.

[0041] In one possible implementation, the mounting base is further provided with:

[0042] An insertion part is formed at the edge of the air inlet of the second fresh air duct, and the insertion part is sealed and inserted into the outlet of the first fresh air outlet so that the second fresh air duct and the first fresh air duct are sealed and connected.

[0043] Therefore, on the one hand, the design of the insertion part can guide the airflow from the first fresh air duct to the second fresh air duct more smoothly when it is delivered. This avoids the fresh air flow from becoming turbulent and eddy at the connection between the first and second fresh air ducts, thereby reducing the mutual interference between the fresh air flows, reducing the noise caused by airflow turbulence, and improving the delivery efficiency of the fresh air flow.

[0044] On the other hand, the insertion part is inserted into the outlet of the first fresh air outlet, forming a nested structure, which helps to enhance the sealing between the first fresh air duct and the second fresh air duct, thereby effectively preventing the fresh air flow from leaking at the connection of the fresh air duct components.

[0045] In one possible implementation, the two opposing surfaces of the partition plate are respectively opposite to the first fresh air outlet and the second fresh air outlet; the air inlet of the second fresh air duct is opposite to the casing.

[0046] This allows fresh air to flow out along both sides, improving the uniformity of fresh air in the indoor space.

[0047] In one possible implementation, the vertical air conditioner indoor unit further includes:

[0048] The first fresh air outlet is rotatably connected to the first fresh air outlet so that the first fresh air outlet can rotate between an open state and a closed state.

[0049] The second fresh air outlet is rotatably connected to the second fresh air outlet so that it can rotate between an open state and a closed state.

[0050] Therefore, by rotating the first and second fresh air outlet components, the air volume of fresh air can be adjusted according to actual needs. On the other hand, when fresh air is not needed, both the first and second fresh air outlet components can be rotated to the closed state to prevent dust, debris, insects and other foreign objects from entering the fresh air module. This helps to keep the fresh air duct components clean, thereby reducing the maintenance cost of the vertical air conditioner indoor unit and extending its service life.

[0051] Compared with the prior art, the beneficial effects of this application are as follows:

[0052] Because the partition can divide the second fresh air duct into a first duct and a second duct, with the first duct connected to the first fresh air outlet and the second duct connected to the second fresh air outlet, the fresh air flow in the first and second ducts is relatively more stable. Furthermore, the flow rate of the fresh air can be adjusted more precisely according to actual conditions. Compared to a scheme where the first and second fresh air outlets are each connected to a separate second fresh air duct, independent first and second ducts can reduce turbulence and impact at the outlet of the fresh air duct, thereby effectively reducing wind noise, providing a quieter indoor environment, and ultimately improving the user experience.

[0074] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0075] As described in the background section, in order to improve the efficiency of fresh air delivery and meet the needs of visualization, some designs place the fresh air outlet on the front side of the casing and adopt a double-sided fresh air outlet structure to increase the fresh air volume. However, when the fresh air is split into two fresh air outlets through a single fresh air channel, the fresh air flow will generate turbulence or impact due to differences in flow velocity or uneven paths, thereby generating noise and affecting the user experience.

[0076] Based on this, this application provides a vertical air conditioner indoor unit that can improve noise and enhance user experience.

[0077] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0078] See Figure 1 This application provides a vertical air conditioner indoor unit 100, which refers to the part of the air conditioning system installed indoors. It is mainly responsible for delivering treated air to the indoor space to achieve functions such as regulating indoor temperature, humidity and air quality.

[0079] Optionally, the vertical air conditioner indoor unit 100 includes a casing 110, which typically houses components such as an evaporator, a fan, a drain pan, an electrical control board, and a temperature sensor. The evaporator is used for heat exchange, the fan drives air circulation, the drain pan collects condensate, the electrical control board controls the operation, and the temperature sensor monitors the indoor temperature, enabling the vertical air conditioner indoor unit 100 to perform its functions.

[0080] Optionally, the indoor unit 100 of the vertical air conditioner also includes a fresh air module, which can filter and purify fresh outdoor air before delivering it indoors to improve indoor air quality and keep the air fresh.

[0081] In some possible embodiments, see Figure 2 The housing 110 has an internal cavity. The housing 110 is provided with a fresh air inlet and a fresh air outlet 111. The fresh air module includes a fresh air duct component 120 and a fresh air fan. The fresh air duct component 120 is disposed in the cavity and forms a first fresh air duct 122. The air inlet end of the first fresh air duct 122 is connected to the fresh air inlet, and the air outlet end of the first fresh air duct 122 is connected to the fresh air outlet 111. The fresh air fan is disposed in the fresh air duct component 120 and is used to introduce fresh air into the first fresh air duct 122 through the fresh air inlet and drive the fresh air to be blown into the room through the fresh air outlet 111.

[0082] Furthermore, the fresh air inlet is connected to the outdoor environment. Thus, under the action of the fresh air fan, fresh air from the outdoor environment can enter the first fresh air duct 122 through the fresh air inlet and be blown into the room through the first fresh air duct 122 and the fresh air outlet 111, thereby improving the indoor air quality.

[0083] In some possible embodiments, the fresh air outlet 111 includes a first fresh air outlet 1111 and a second fresh air outlet 1112, with the second fresh air outlet 1112 and the first fresh air outlet 1111 spaced apart along the width direction of the housing 110.

[0084] Wherein, the width direction of the housing 110 refers to the direction perpendicular to the height direction and the thickness direction of the housing 110, that is, as shown in the figure. Figure 1 As shown, the width direction of the housing 110 is the direction indicated by the X arrow, the thickness direction of the housing 110 is the direction indicated by the Y arrow, and the height direction of the housing 110 is the direction indicated by the Z arrow.

[0085] In addition, by setting a first fresh air outlet 1111 and a second fresh air outlet 1112, and setting the first fresh air outlet 1111 and the second fresh air outlet 1112 at intervals along the width direction of the casing 110, on the one hand, the air volume of fresh air can be increased, and on the other hand, fresh air can be introduced from two different positions, so that the fresh air can more comprehensively cover the indoor space. Compared with the setting of a single fresh air outlet 111, the dead corners of fresh air delivery can be reduced, avoiding the situation that some areas have sufficient fresh air while other places have difficulty in receiving fresh air, thereby improving the air quality of the indoor space.

[0086] In some possible embodiments, see Figure 2 and Figure 3The housing 110 is also provided with a mounting base 113 and a partition plate 130. The mounting base 113 is connected to the air outlet of the fresh air duct component. A second fresh air duct 123 is formed in the mounting base 113 and communicates with the first fresh air duct 122. The second fresh air duct 123 is also communicated with the first fresh air outlet 1111 and the second fresh air outlet 1112 respectively. The partition plate 130 is disposed on the mounting base 113 and located in the second fresh air duct 123. The partition plate 130 can divide the second fresh air duct 123 into a first air duct 120a and a second air duct 120b. The first air duct 120a is communicated with the first fresh air outlet 1111, and the second air duct 120b is communicated with the second fresh air outlet 1112.

[0087] Since the partition plate 130 can divide the second fresh air duct 123 into a first air duct 120a and a second air duct 120b, with the first air duct 120a connected to the first fresh air outlet 1111 and the second air duct 120b connected to the second fresh air outlet 1112, the fresh air flow in the first air duct 120a and the second air duct 120b is relatively more stable, and the flow rate of the fresh air flow can be adjusted more precisely according to the actual situation. Compared with the scheme where the first fresh air outlet 1111 and the second fresh air outlet 1112 are each connected to a second fresh air duct 123, the independent first air duct 120a and the second air duct 120b can reduce the turbulence and impact of the airflow at the outlet end of the second fresh air duct 123, thereby effectively reducing wind noise, providing a quieter indoor environment, and thus improving the user experience.

[0088] In some possible embodiments, see Figure 2 The mounting base 113 is detachably connected to the fresh air duct component 120.

[0089] The mounting base 113 is detachably connected to the fresh air duct component 120, which facilitates maintenance should either the mounting base 113 or the fresh air duct component 120 be damaged.

[0090] In some possible embodiments, see Figure 3 and Figure 4 In the width direction of the housing 110, the partition plate 130 is located in the middle of the second fresh air duct 123.

[0091] It should be noted that, in the width direction of the housing 110, the partition plate 130 is located in the middle of the second fresh air duct 123. It should be understood that, in the width direction of the housing 110, the partition plate 130 is located in the middle of the second fresh air duct 123, or the partition plate 130 is located around the middle of the second fresh air duct 123.

[0092] Therefore, by positioning the partition plate 130 in the middle of the second fresh air duct 123 in the width direction of the housing 110, the fresh air flow can be evenly distributed to the independent first air duct 120a and second air duct 120b, thereby allowing the fresh air flow to be evenly delivered from the first fresh air outlet 1111 and the second fresh air outlet 1112, which is beneficial to improving the uniformity of indoor air quality.

[0093] On the other hand, the partition plate 130 located in the middle can make the airflow path and resistance in the first air duct 120a and the second air duct 120b approximately the same, which helps to balance the airflow pressure in the first air duct 120a and the second air duct 120b, thereby reducing the risk of increased noise.

[0094] On the other hand, the partition 130 being located in the middle helps to achieve a symmetrical design of the appearance of the vertical air conditioner indoor unit 100, thereby enhancing the visual effect and quality of the product and meeting the user's aesthetic needs for the product's appearance.

[0095] In some possible embodiments, see Figure 5 The first side 131 of the partition plate 130, which is away from the first fresh air duct 122, is sealed to the inner wall of the casing 110.

[0096] Since the first side 131 of the partition plate 130, which is away from the first fresh air duct 122, is sealed to the inner wall of the casing 110, on the one hand, it ensures that the fresh air flow can only be delivered through the independent first air duct 120a and the corresponding first fresh air outlet 1111, and the second fresh air outlet 1112 corresponding to the second air duct 120b, thus avoiding air leakage at the connection between the partition plate 130 and the inner wall of the casing 110.

[0097] On the other hand, the sealed connection allows the fresh air to flow stably within the first air duct 120a and the second air duct 120b, preventing airflow disturbances, vortices, or backflows caused by the gap between the partition plate 130 and the casing 110, thus further ensuring the quietness of the indoor space.

[0098] In some possible embodiments, see Figure 5 A flexible connection portion 112 is provided on the inner wall of the housing 110; the first side 131 of the partition plate 130 abuts against the flexible connection portion 112 so that the partition plate 130 is sealed to the housing 110.

[0099] Since the first side 131 of the partition plate 130 abuts against the flexible connection part 112 to seal the partition plate 130 with the housing 110, the flexible connection part 112 can adaptively deform according to the installation position of the partition plate 130 and the shape of the inner wall of the housing 110, and closely fit the first side 131 of the partition plate 130. Even if the housing 110 has certain manufacturing errors or undergoes slight deformation after installation, it can still ensure a good sealing effect and effectively prevent fresh air leakage.

[0100] On the other hand, when the fresh air module is running, the casing 110 or partition plate 130 may be slightly displaced due to factors such as vibration of the fresh air fan and temperature changes. The flexible connection part 112 can compensate for these displacements through its own elastic deformation, maintain a sealed state, ensure that the fresh air flow follows the designed path, and improve the stability and reliability of the fresh air module.

[0101] On the other hand, since the flexible connection part 112 is elastic, it can absorb and buffer the vibration generated from the operation of the fresh air module to reduce the vibration amplitude of the housing 110. Therefore, the noise generated by vibration friction between the housing 110 and the partition plate 130 will also be reduced accordingly. At the same time, the flexible connection part 112 can also block the airflow noise in the duct from spreading outward, creating a quieter environment indoors.

[0102] It should be noted that the material of the flexible connection part 112 includes, but is not limited to, sponge, latex, etc.

[0103] In some possible embodiments, see Figure 6 The first side 131 of the partition plate 130 is flush with the end face of the second fresh air duct 123 away from the first fresh air duct 122.

[0104] Since the first side 131 of the partition plate 130 is flush with the end face of the second fresh air duct 123 away from the first fresh air duct 122, the flush design ensures that the ends of the independent first air duct 120a and second air duct 120b near the housing 110 are on the same plane. Therefore, it ensures that the flow conditions of the fresh air at the outlet of the first air duct 120a and the second air duct 120b are basically the same, avoiding the uneven airflow caused by the difference in the flow conditions of the fresh air at the outlet of the first air duct 120a and the second air duct 120b.

[0105] On the other hand, the flush design can reduce the possibility of impurities accumulating in the gap between the partition plate 130 and the end face of the housing 110, thereby helping to maintain the cleanliness of the fresh air.

[0106] In some possible embodiments, see Figure 6 The partition plate 130 is also sealed to the inner wall of the second fresh air duct 123.

[0107] The partition plate 130 is also sealed to the inner wall of the second fresh air duct 123. On the one hand, it can effectively prevent the fresh air flow from leaking into the fresh air duct component 120, thereby avoiding the fresh air flow from mixing with other air flows (such as return air flow or outside air flow), and thus improving the ventilation effect and air quality of the indoor space.

[0108] On the other hand, the sealed connection ensures that the fresh airflow can only flow out through the independently designed first air duct 120a and second air duct 120b, and is delivered in a predetermined proportion and direction, thereby improving the controllability and comfort of the fresh airflow.

[0109] On the other hand, it can make the flow of fresh air within the fresh air duct 120 more stable and smooth, reducing the risk of noise, vibration and other phenomena caused by leakage or disturbance of fresh air flow.

[0110] In some possible embodiments, see Figure 7 The cross-sectional area of ​​the first fresh air duct 122 is smaller than the cross-sectional area of ​​the second fresh air duct 123.

[0111] The cross-section of the first fresh air duct 122 refers to the cross-section along the extension direction perpendicular to the first fresh air duct 122. Similarly, the cross-section of the second fresh air duct 123 refers to the cross-section along the extension direction perpendicular to the second fresh air duct 123.

[0112] Since the cross-sectional area of ​​the first fresh air duct 122 is smaller than that of the second fresh air duct 123, on the one hand, according to the principle of fluid continuity, under the condition of a certain fresh air flow rate, the larger cross-sectional area of ​​the second fresh air duct 123 will slow down the flow rate of the fresh air at this point. Therefore, when the fresh air flows out of the second fresh air duct 123 and enters the indoor space, it can diffuse at a lower speed, which is conducive to the design of the soft wind at the fresh air outlet 111, thereby providing a more comfortable air environment for indoor occupants.

[0113] On the other hand, since the cross-sectional area of ​​the second fresh air duct 123 is larger than that of the first fresh air duct 122, and the air velocity of the fresh air flow in the second fresh air duct 123 is lower than that in the first fresh air duct 122, the friction of the fresh air flow in the second fresh air duct 123 on the inner wall of the fresh air duct component 120 is reduced, thereby effectively reducing wind noise.

[0114] In some possible embodiments, see Figure 7The mounting base 113 is also provided with an insertion part 1231, which is formed at the edge of the air inlet of the second fresh air duct 123. The insertion part 1231 is sealed and inserted into the outlet of the first fresh air outlet 1111 so that the second fresh air duct 123 and the first fresh air duct 122 are sealed and connected.

[0115] Based on the structure in this embodiment, on the one hand, the design of the insertion part 1231 allows the airflow from the first fresh air duct 122 to be guided by the insertion part 1231 when it is sent out, and is sent into the second fresh air duct 123 more smoothly. This avoids the fresh airflow from becoming turbulent and eddy at the connection between the first fresh air duct 122 and the second fresh air duct 123, thereby reducing the mutual interference between the fresh airflows, reducing the noise caused by airflow turbulence, and also improving the delivery efficiency of the fresh airflow.

[0116] On the other hand, the insertion part 1231 is sealed and inserted into the outlet of the first fresh air outlet 1111, forming a nested structure, which helps to enhance the sealing between the first fresh air duct 122 and the second fresh air duct 123, thereby effectively preventing the fresh air flow from leaking at the connection of the fresh air duct component 120.

[0117] In one possible embodiment, see Figure 5 and Figure 8 The two opposing surfaces of the partition plate 130 are respectively opposite to the first fresh air outlet 1111 and the second fresh air outlet 1112; the air inlet of the second fresh air duct 123 is opposite to the casing 110.

[0118] In this way, a portion of the fresh air flow delivered from the second fresh air duct 123 will collide with the casing 110, and then the fresh air flow that collided with the casing 110 will be reflected and flowed to the first fresh air outlet 1111 and the second fresh air outlet 1112 on both sides, thereby improving the uniformity of fresh air in the indoor space.

[0119] In some possible embodiments, see Figure 8 , Figure 9 and Figure 10 The vertical air conditioner indoor unit 100 also includes a first fresh air outlet 141 and a second fresh air outlet 142. The first fresh air outlet 141 is rotatably connected to the first fresh air outlet 1111 so that the first fresh air outlet 141 can rotate between an open state and a closed state. The second fresh air outlet 142 is rotatably connected to the second fresh air outlet 1112 so that the second fresh air outlet 142 can rotate between an open state and a closed state.

[0120] Therefore, by rotating the first fresh air outlet 141 and the second fresh air outlet 142, the air volume of fresh air can be adjusted according to actual needs. On the other hand, when fresh air is not needed, both the first fresh air outlet 141 and the second fresh air outlet 142 can be rotated to the closed state to prevent dust, debris, insects and other foreign objects from entering the fresh air module. This helps to keep the fresh air duct 120 clean, thereby reducing the maintenance cost of the vertical air conditioner indoor unit 100 and extending the service life of the vertical air conditioner indoor unit 100.
