Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a vertical air conditioner. Background Art

[0002] A vertical air conditioner includes an indoor unit, which includes a housing having a first cavity formed therein. The housing is provided with a heat exchange inlet and a heat exchange outlet, wherein both the heat exchange inlet and the heat exchange outlet are connected to the first cavity. The indoor unit also includes an indoor heat exchanger and a heat exchange fan, both of which are disposed within the first cavity. The heat exchange fan is disposed in front of the indoor heat exchanger. Driven by the heat exchange fan, indoor air enters the first cavity through the indoor air inlet. The indoor air entering the first cavity exchanges heat with the indoor heat exchanger and then flows out through the heat exchange outlet. To improve the air quality of the indoor environment, a fresh air module can be added to the indoor unit. The fresh air module can be used to introduce fresh outdoor air into the room, thereby refreshing the indoor air and improving the quality of the indoor environment.

[0003] For the indoor unit of a vertical air conditioner, the fresh air module is typically located at the bottom of the unit to facilitate the introduction of fresh air and the arrangement of the unit's components. Specifically, a second chamber is typically positioned below the first chamber, with the fresh air volute positioned within the second chamber. The housing is provided with a fresh air inlet and outlet, both of which communicate with the second chamber. The fresh air module usually includes a fresh air fan and a fresh air volute. The fresh air fan of the fresh air fan is arranged in the fan cavity. The fresh air volute includes a volute air inlet and a volute air outlet connected with the fan cavity. In order to guide the fresh air from the fresh air volute to the fresh air outlet, the fresh air module also includes a guide member. The guide member includes a guide member air inlet connected with the fan cavity and a guide member air outlet for air outlet. Driven by the fresh air fan, outdoor fresh air enters the fan cavity from the fresh air inlet, then enters the guide member from the fan cavity, and then enters the room through the guide member air outlet.

[0004] At present, in order to achieve the mixed air function of mixing fresh air and heat exchange air and then outputting it, the guide member needs to be set at an angle relative to the horizontal plane. However, the indoor unit usually also needs to be equipped with a sliding door and a motion mechanism. The motion mechanism drives the sliding door to close or open the heat exchange air outlet. Since the heat exchange air outlet, the motion mechanism and the guide member are all arranged at intervals along the height direction of the casing, and the inclined guide member needs to occupy more space in the height direction, the indoor unit has insufficient space in the height direction. Utility Model Content

[0005] An embodiment of the present utility model discloses a vertical air conditioner, in which an air guide is arranged at an angle relative to a horizontal plane, so as to realize the air mixing function of mixing fresh air and heat exchange air. At the same time, a motion mechanism is arranged in an installation space formed between the air guide and the installation portion, and the structural arrangement is relatively compact, which can reduce the size of the indoor unit of the vertical air conditioner in the height direction.

[0006] In order to achieve the above object, the utility model discloses a vertical air conditioner, comprising:

[0007] Indoor unit;

[0008] Wherein, the indoor unit includes:

[0009] a casing, wherein a first cavity and a second cavity are formed in the casing, the first cavity is located above the second cavity, the casing has a heat exchange outlet and a fresh air outlet, and the heat exchange outlet and the fresh air outlet are spaced apart along the height direction of the casing, the heat exchange outlet is in communication with the first cavity, and the fresh air outlet is in communication with the second cavity;

[0010] a heat exchange volute, disposed in the first cavity;

[0011] an indoor heat exchanger for exchanging heat with indoor air entering the casing;

[0012] a heat exchange fan, disposed in the heat exchange volute and located in front of the indoor heat exchanger;

[0013] Fresh air module, the fresh air module includes:

[0014] A fresh air volute is disposed in the second cavity, the fresh air volute having a fan cavity, and the fresh air volute is provided with a volute air outlet located above the fan cavity and in communication with the fan cavity;

[0015] A fresh air fan is provided in the fresh air volute;

[0016] an air guide member disposed above the fresh air volute, the air guide member having an air guide duct, the air guide member having a front end and a rear end, the front end being provided with a first air outlet, the rear end being provided with a first air inlet, the first air outlet and the first air inlet being communicated with the air guide duct, the first air inlet being communicated with the volute air outlet, the first air outlet being communicated with the fresh air outlet, the air guide member being inclined relative to a horizontal plane, and the front end of the air guide member being located above the rear end of the air guide member, so as to form an installation space between the air guide member and the casing;

[0017] Wherein, the indoor unit further includes:

[0018] A motion mechanism, disposed in the installation space;

[0019] The door body is connected to the motion mechanism, and the motion mechanism is used to drive the door body to move so as to simultaneously open or close the heat exchange air outlet and the fresh air outlet.

[0020] In some embodiments of the present application, a vertical air conditioner is formed on a casing with a heat exchange outlet and a fresh air outlet spaced apart along the height direction of the casing. Driven by a heat exchange blower, indoor air in a first chamber exchanges heat with an indoor heat exchanger, and then flows out of the heat exchange outlet as heated air. Driven by the fresh air blower, fresh air flows out of a volute outlet of a fresh air volute. Furthermore, a guide member is provided, wherein a first air inlet at a rear end of the guide member is connected to the volute outlet, and a first air outlet at a front end of the guide member is connected to the fresh air outlet, thereby guiding the fresh air to flow out of the fresh air outlet. Furthermore, by tilting the guide member relative to a horizontal plane, the direction of the fresh air flowing out of the fresh air outlet is angled relative to the horizontal plane, thereby causing the heat exchange air flowing out of the heat exchange outlet to mix with the fresh air flowing out of the fresh air outlet, thereby achieving a mixed air function of heat exchange air and mixed air, thereby improving the user experience. In addition, an installation space is formed between the guide member that is inclined relative to the horizontal plane and the casing. The motion mechanism is set in the installation space. On the one hand, the internal space of the indoor unit can be reasonably utilized, and the structural arrangement is relatively compact. When the mixing function of heat exchange air and mixed air can be realized (that is, the guide member is inclined relative to the horizontal plane), the size of the indoor unit of the vertical air conditioner in the height direction can also be reduced; on the other hand, the motion device is located below the heat exchange outlet and the fresh air outlet, so that the door body driven by the motion mechanism opens or closes the heat exchange outlet and the fresh air outlet at the same time. Only one set of motion mechanism and door body needs to be set, and there is no need to set two sets of motion mechanisms and door bodies for the heat exchange outlet and the fresh air outlet respectively. This simplifies the structure of the vertical air conditioner and further reduces the size of the indoor unit of the vertical air conditioner in the height direction.

[0021] The utility model also discloses a vertical air-conditioning indoor unit, comprising:

[0022] Indoor unit;

[0023] Wherein, the indoor unit includes:

[0024] a casing, wherein a first cavity and a second cavity are formed in the casing, the first cavity is located above the second cavity, the casing has a heat exchange outlet and a fresh air outlet, and the heat exchange outlet and the fresh air outlet are spaced apart along the height direction of the casing, the heat exchange outlet is in communication with the first cavity, and the fresh air outlet is in communication with the second cavity;

[0025] a heat exchange volute, disposed in the first cavity;

[0026] an indoor heat exchanger for exchanging heat with indoor air entering the casing;

[0027] a heat exchange fan, disposed in the heat exchange volute and located in front of the indoor heat exchanger;

[0028] a motion mechanism, located in the second cavity;

[0029] a door body connected to the motion mechanism, wherein the motion mechanism is used to drive the door body to move so as to simultaneously open or close the heat exchange air outlet and the fresh air outlet;

[0030] Fresh air module, the fresh air module includes:

[0031] A fresh air volute is disposed in the second cavity, the fresh air volute having a fan cavity, and the fresh air volute is provided with a volute air outlet located above the fan cavity and in communication with the fan cavity;

[0032] A fresh air fan is provided in the fresh air volute;

[0033] The guide member is arranged above the fresh air volute, the guide member has a guide air duct, the guide member has a front end and a rear end, the front end is provided with a first air outlet, the rear end is provided with a first air inlet, the first air outlet and the first air inlet are connected with the guide air duct, the first air inlet is connected with the volute air outlet, the first air outlet is connected with the fresh air outlet, the guide member is inclined relative to the horizontal plane, and the front end of the guide member is located above the rear end of the guide member to form an installation space between the guide member and the casing, and the installation space is configured to accommodate at least part of the motion mechanism.

[0034] In some embodiments of the vertical air conditioner of the present application, a heat exchange outlet and a fresh air outlet are formed on the casing and are spaced apart along the height direction of the casing. Driven by the heat exchange fan, the indoor air in the first cavity exchanges heat with the indoor heat exchanger, and the heat exchange air can flow out from the heat exchange outlet. Driven by the fresh air fan, the fresh air can flow out from the volute outlet of the fresh air volute, and by setting a guide member, the first air inlet at the rear end of the guide member is connected with the volute outlet, and the first air outlet at the front end of the guide member is connected with the fresh air outlet, thereby guiding the fresh air to flow out from the fresh air outlet. At the same time, by making the guide member tilt relative to the horizontal plane, the direction of the fresh air flowing out of the fresh air outlet has a certain angle with the horizontal plane, so that the heat exchange air flowing out of the heat exchange outlet is mixed with the fresh air flowing out of the fresh air outlet, realizing the mixed air function of the heat exchange air and the mixed air, thereby improving the user experience. Furthermore, the inclined air guide relative to the horizontal plane creates an installation space between the air guide and the housing. This space is used to accommodate at least part of the motion mechanism. This, on the one hand, allows for more efficient use of the indoor unit's internal space, resulting in a more compact structural layout. While achieving the mixing function of heat exchange air and mixed air (i.e., the inclined air guide relative to the horizontal plane), it also reduces the height of the indoor unit of the vertical air conditioner. Furthermore, the motion mechanism is located below the heat exchange outlet and the fresh air outlet, allowing the door driven by the motion mechanism to simultaneously open or close both outlets. This simplifies the structure of the vertical air conditioner and further reduces the height of the indoor unit.

[0035] As an optional implementation, in an embodiment of the present utility model, the air guide comprises a first part and a second part connected to each other, the first part has the first air inlet, and the second part has the first air outlet;

[0036] The angle between the first portion and the horizontal plane is greater than the angle between the second portion and the horizontal plane.

[0037] On the one hand, when fresh air flows out from the volute outlet, it usually flows upward. By making the angle between the first part and the horizontal plane greater than the angle between the second part and the horizontal plane, in the process of the fresh air passing through the first part and the second part in sequence from the volute outlet and then flowing out from the fresh air outlet, the flow direction of the fresh air in the first part is changed from the vertical direction to a smaller angle with the vertical direction, and then the flow direction of the fresh air in the second part is changed from a smaller angle with the vertical direction to a larger angle with the vertical direction, which can play a transitional role in the change of the flow direction of the fresh air, reduce the loss of the flow velocity of the fresh air, and increase the flow velocity of the fresh air flowing out of the fresh air outlet; on the other hand, by making the angle between the second part and the horizontal plane relatively small, the size of the guide member in the height direction of the casing can be reduced, thereby reducing the size of the indoor unit of the vertical air conditioner in the height direction; on the other hand, due to the angle between the first part and the second part, the capacity of the installation space is relatively large (when the length of the base and the length of the side are the same, the area of ​​the quadrilateral is larger than that of the triangle), which is conducive to accommodating the motion mechanism.

[0038] As an optional implementation, in an embodiment of the present utility model, the second portion includes a first connecting plate, a second connecting plate, a third connecting plate, and a fourth connecting plate connected end to end in sequence to enclose and form the first air outlet, and the first connecting plate is located above the second connecting plate, the third connecting plate, and the fourth connecting plate;

[0039] The first connecting plate and the third connecting plate are arranged obliquely relative to the horizontal plane.

[0040] Since the shape of the fresh air outlet is usually rectangular, by setting the second part as a first connecting plate, a second connecting plate, a third connecting plate and a fourth connecting plate connected end to end in sequence, the shape of the first air outlet (and the cross-section of the guide air duct) is also rectangular, that is, the shape of the first air outlet matches the shape of the fresh air outlet, which can reduce the loss of fresh air volume. By setting the first connecting plate and the third connecting plate to be inclined relative to the horizontal plane, the first connecting plate and the third connecting plate can guide the flow of fresh air, so that the flow direction of the fresh air when flowing out of the fresh air outlet is inclined relative to the horizontal plane, thereby achieving mixing of fresh air and heat exchange air.

[0041] As an optional implementation, in an embodiment of the present utility model, the angle between the first connecting plate and the horizontal plane is a1, and the angle a1 satisfies: a1≤40°, and / or a1≥10°;

[0042] The included angle between the third connecting plate and the horizontal plane is a2, and the included angle a2 satisfies: a2≤40°, and / or a2≥10°.

[0043] On the one hand, the angle a1 between the first connecting plate and the horizontal plane is less than or equal to 40°, and the angle a2 between the third connecting plate and the horizontal plane is less than or equal to 40°. When the dimensions of the first connecting plate and the third connecting plate in the thickness direction of the casing remain unchanged, the dimensions of the first connecting plate and the third connecting plate in the height direction of the casing can be made relatively small, thereby making the dimension of the air guide member in the height direction of the casing relatively small, thereby reducing the dimension of the indoor unit of the vertical air conditioner in the height direction; on the other hand, the angle a1 between the first connecting plate and the horizontal plane is greater than or equal to 10°, and the angle a2 between the third connecting plate and the horizontal plane is greater than or equal to 10°, thereby ensuring that the flow direction of the fresh air flowing out of the fresh air outlet through the second part has a certain angle with the horizontal plane, that is, the flow direction of the fresh air has a certain angle with the flow direction of the heat exchange air, thereby ensuring that the fresh air and the heat exchange air have a better mixing effect.

[0044] As an optional implementation, in an embodiment of the present invention, a transition portion is provided between the first connecting plate and the second connecting plate, and / or a transition portion is provided between the first connecting plate and the fourth connecting plate.

[0045] Because the fresh air is mainly blocked by the first connecting plate of the second part during its flow from the first part to the second part, changing its flow direction, the fresh air is mainly concentrated in the upper half of the first part, that is, the fresh air is concentrated in the area close to the first connecting plate. This results in a more serious vortex phenomenon of the fresh air at the angle between the first connecting plate and the second connecting plate, and at the angle between the first connecting plate and the fourth connecting plate. This in turn causes the air guide to easily produce abnormal noise at this position, affecting the service life of the air guide and the user's experience. With this arrangement, the transition portion can reduce the vortex phenomenon of the fresh air at the angle between the first connecting plate and the second connecting plate, and at the angle between the first connecting plate and the fourth connecting plate, thereby reducing the abnormal noise phenomenon of the air guide at this position, improving the service life of the air guide and affecting the user's experience. At the same time, the transition portion can also reduce stress concentration at the connection between the first connecting plate and the second connecting plate, and at the connection between the first connecting plate and the fourth connecting plate, thereby improving the structural strength of the air guide.

[0046] As an optional implementation, in an embodiment of the present invention, the transition portion is an arc transition portion, the radius of the transition portion is R, and the radius R satisfies: R≥15mm, and / or, R≤25mm.

[0047] When the transition portion is an arc transition portion, the flow of fresh air at the angle between the first connecting plate and the second connecting plate and at the angle between the first connecting plate and the fourth connecting plate can be made more uniform, further reducing the vortex phenomenon of the fresh air at this position, thereby further reducing the abnormal noise phenomenon of the guide member at this position. By designing the radius of the transition portion. On the one hand, making the radius R of the transition portion greater than or equal to 15mm, the transition portion can have a sufficient size to make the transition at the angle between the first connecting plate and the second connecting plate smoother, thereby ensuring the effect of the transition portion in reducing the vortex phenomenon of the fresh air; on the other hand, making the radius R of the transition portion less than or equal to 25mm can avoid the size of the transition portion being too large, which greatly affects the size of the first air outlet, thereby ensuring the air volume of fresh air flowing out of the first air outlet.

[0048] As an optional implementation, in an embodiment of the present utility model, the fresh air module further includes an air outlet grille, and the air outlet grille is provided at the first air outlet;

[0049] The air outlet grille includes a plurality of grille bars spaced apart along a height direction of the housing, and the grille bars are inclined relative to the horizontal plane.

[0050] By providing an air outlet grille at the first air outlet, the air outlet grille includes multiple grille bars that can guide the fresh air, ensuring a more uniform flow of the fresh air flowing out of the first air outlet. Furthermore, by angling the grille bars relative to the horizontal plane, the grille bars can also guide the fresh air, further ensuring that the fresh air flowing out of the first air outlet has a certain angle with the horizontal plane, thereby improving the mixing effect of the fresh air and the heat exchange air.

[0051] As an optional implementation, in an embodiment of the present utility model, the angle between the grille bars and the horizontal plane is a3, and the angle a3 satisfies: a3≤40°, and / or a3≥10°.

[0052] On the one hand, making the angle a3 between the grille bars and the horizontal plane less than or equal to 40° can reduce the blocking area of ​​the grille bars on the fresh air and avoid the grille bars from excessively affecting the air output of the fresh air; on the other hand, making the angle a3 between the grille bars and the horizontal plane greater than or equal to 10° can ensure that the flow direction of the fresh air flowing out of the fresh air outlet through the grille bars has a certain angle with the horizontal plane, that is, the flow direction of the fresh air and the flow direction of the heat exchange air have a certain angle, thereby ensuring that the fresh air and the heat exchange air have a better mixing effect.

[0053] As an optional implementation, in an embodiment of the present utility model, in the width direction of the casing, the width of the heat exchange outlet is the same as the width of the fresh air outlet.

[0054] On the one hand, the width of the heat exchange air flowing out of the heat exchange outlet and the fresh air flowing out of the fresh air outlet can be made roughly the same, so that the heat exchange air and the fresh air can be better mixed in different areas in the width direction of the casing, thereby improving the uniformity of the mixing of the heat exchange air and the fresh air. On the other hand, the heat exchange outlet and the fresh air outlet can have better appearance consistency, and from the appearance, the heat exchange outlet and the fresh air outlet form a large outlet, thereby improving the aesthetics of the appearance.

[0055] As an optional implementation, in an embodiment of the present utility model, in the width direction of the casing, the width of the casing is d1, the width of the heat exchange outlet is d2, and the width of the fresh air outlet is d3;

[0056] The width d2 satisfies: d2≤1 / 2d1, and / or d2≥1 / 3d1, and the width d3 satisfies: d3≤1 / 2d1, and / or d3≥1 / 3d1.

[0057] On the one hand, making the width d2 of the heat exchange outlet greater than or equal to 1 / 3 of the width d1 of the casing, and making the width d3 of the fresh air outlet greater than or equal to 1 / 3 of the width d1 of the casing, can make the widths of the heat exchange outlet and the fresh air outlet relatively large, thereby increasing the widths of the outlet areas of the heat exchange air and the fresh air, and meeting the user's demand for air conditioning with large air outlets; on the other hand, making the width d2 of the heat exchange outlet less than or equal to 1 / 2 of the width d1 of the casing, and making the width d3 of the fresh air outlet less than or equal to 1 / 2 of the width d1 of the casing, can avoid the widths of the heat exchange outlet and the fresh air outlet being too large, resulting in insufficient space in the width direction between the first cavity and the second cavity of the casing, affecting the arrangement of other components in the casing (such as the heat exchange volute and the fresh air volute, etc.).

[0058] As an optional embodiment, in an embodiment of the present utility model, the casing includes an outer shell and a panel seat, the first cavity and the second cavity are formed in the outer shell, the panel seat is arranged in the outer shell, the panel seat has the heat exchange outlet and the fresh air outlet, the panel seat is provided with a mounting portion, the mounting portion is located below the fresh air outlet, and the mounting space is formed between the guide member and the mounting portion.

[0059] The housing, as the exterior structural component of the indoor unit, shields the unit's internal structure, enhancing its aesthetics. The panel seat, as an internal structural component, forms the heat exchange and fresh air outlets and serves as the mounting base for components such as the heat exchange volute, motion mechanism, and door. Furthermore, a mounting portion is provided on the panel seat, positioned below the fresh air outlet, creating a mounting space between the air guide and the mounting portion to accommodate the motion mechanism. The mounting portion also provides support for the motion mechanism, facilitating its installation on the housing.

[0060] As an optional embodiment, in an embodiment of the present invention, the casing further includes an air guide plate, which is arranged on the panel seat, and the air guide plate is extended along the height direction of the casing, and in the direction from the front side of the casing toward the rear side of the casing, the projection of the air guide plate on the panel seat at least covers the heat exchange outlet and the fresh air outlet.

[0061] By rotating the air guide plate, it can simultaneously guide the heat exchange air and fresh air, changing the outlet angle of the heat exchange air and fresh air, thus realizing the indoor unit's air sweeping function. In addition, because the air guide plate's projection on the panel seat covers the heat exchange air outlet and the fresh air outlet, it can to a certain extent block the casing between the heat exchange air outlet and the fresh air outlet, making the heat exchange air outlet and the fresh air outlet appear more like a large outlet, improving the indoor unit's appearance.

[0062] As an optional implementation, in an embodiment of the present utility model, the indoor unit further includes a water receiving tray, and the water receiving tray is provided between the heat exchange volute and the flow guide;

[0063] In the height direction of the casing, the distance between the heat exchange outlet and the fresh air outlet is L, and the distance L satisfies: L≤80mm, and / or, L≥60mm.

[0064] Since condensation is easily formed on the air guide plate when the heat exchange fan outputs heated air to the heat exchange outlet, a water collection tray is installed between the heat exchange volute and the air guide to collect condensation, preventing it from dripping directly from the air guide plate onto the floor and affecting the user experience. By designing the distance L between the heat exchange outlet and the fresh air outlet, on the one hand, by setting the distance L to less than or equal to 80 mm, the distance between the heat exchange outlet and the fresh air outlet can be kept relatively small, making it easier to mix the heat exchange air and the fresh air. At the same time, the heat exchange outlet and the fresh air outlet appear to be a single large outlet, improving the aesthetics of the indoor unit. On the other hand, by setting the distance L to greater than or equal to 60 mm, sufficient space is ensured within the first cavity corresponding to the heat exchange outlet and the fresh air outlet to accommodate components such as the water collection tray and the bottom shell of the heat exchange volute.

[0100] In some embodiments, an outdoor accommodation space is provided in the outdoor housing, wherein the outdoor fan and the outdoor heat exchanger are provided in the outdoor accommodation space.

[0101] In some embodiments, the outdoor housing is provided with an outdoor air inlet and an outdoor air outlet, wherein both the outdoor air inlet and the outdoor air outlet are in communication with the outdoor receiving space. The outdoor air inlet is used to introduce outdoor air into the outdoor receiving space, and the outdoor air outlet is used to draw air from the outdoor receiving space to the outside of the outdoor receiving space.

[0102] In some embodiments, the rotation of the outdoor fan causes outdoor air to enter the outdoor accommodation space from the outdoor air inlet and exchange heat with the outdoor heat exchanger, and the outdoor air after heat exchange flows out of the outdoor accommodation space from the outdoor air outlet.

[0103] In some embodiments, the air-conditioning outdoor unit further includes a compressor and a throttling device, and the compressor and the throttling device are both arranged in the outdoor accommodation space.

[0104] In some embodiments, a vertical air conditioner performs a refrigeration cycle of the vertical air conditioner using a compressor, a condenser, a throttling device, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0105] In some embodiments, the compressor compresses the refrigerant gas in a low-temperature and low-pressure state and discharges the refrigerant gas in a high-temperature and high-pressure state, and the discharged refrigerant gas flows into the condenser.

[0106] In some embodiments, the condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0107] In some embodiments, the throttling device expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant.

[0108] In some embodiments, the evaporator evaporates the refrigerant expanded in the throttling device and returns the refrigerant gas at a low temperature and low pressure to the compressor.

[0109] In some embodiments, the evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. Throughout the cycle, the vertical type can regulate the temperature of the indoor space.

[0110] In some embodiments, among both the indoor heat exchanger and the outdoor heat exchanger, one is a condenser and the other is an evaporator. When the indoor heat exchanger is used as a condenser, the stand-alone air conditioner is used as a heater in the heating mode, and when the indoor heat exchanger is used as an evaporator, the stand-alone air conditioner is used as a cooler in the cooling mode.

[0111] Please also refer to Figures 2 to 5 In some embodiments, the indoor unit 1 further includes a fresh air module 12, which is used to introduce outdoor air into the room.

[0112] In some embodiments, the casing 10 further has a fresh air inlet 104 and a fresh air outlet 105, the fresh air inlet 104 and the fresh air outlet 105 are connected to the second cavity 101, the heat exchange inlet 102 and the fresh air inlet 104 are both located on the rear side of the casing 10, the heat exchange outlet 103 and the fresh air outlet 105 are both located on the front side of the casing 10, and the heat exchange outlet 103 and the fresh air outlet 105 are spaced apart along the height direction X of the casing 10.

[0113] In some embodiments, the fresh air module 12 includes a fresh air volute 120 and a fresh air fan 121 , wherein the fresh air volute 120 is disposed in the second cavity 101 , the fresh air volute 120 has a fan cavity, and the fresh air volute 120 is disposed in front of the fresh air inlet 104 .

[0114] In some embodiments, the fresh air blower 121 is disposed in the fresh air volute 120 , and the fresh air blower 121 includes a fresh air fan and a fresh air motor, wherein the fresh air fan is disposed in the blower cavity.

[0115] In some embodiments, the rotation of the fresh air fan 121 allows outdoor fresh air to enter the housing 10 through the fresh air inlet 104, and the outdoor fresh air flows into the room through the fan cavity.

[0116] In some embodiments, the fan cavity can be connected to the heat exchange outlet 103. The rotation of the fresh air fan 121 allows outdoor fresh air to enter the housing 10 through the fresh air inlet 104. The outdoor fresh air flows through the fan cavity and the heat exchange outlet 103 to the indoor room. Alternatively, the housing 10 is formed with a fresh air outlet 105, which is connected to the volute outlet 1200 of the fan cavity. The rotation of the fresh air fan 121 allows outdoor fresh air to enter the housing 10 through the fresh air inlet 104. The outdoor fresh air flows through the fan cavity and the fresh air outlet 105 to the indoor room.

[0117] In some embodiments, the fresh air module 12 also includes a fresh air hood 122, which is arranged in the second cavity 101. The fresh air hood 122 is located between the fresh air volute 120 and the fresh air inlet 104, that is, the fresh air hood 122 is arranged behind the fresh air volute 120, and the fresh air hood 122 is arranged in front of the fresh air inlet 104.

[0118] In some embodiments, the rotation of the fresh air fan 121 causes outdoor fresh air to enter the casing 10 through the fresh air inlet 104, and the outdoor fresh air flows into the room through the fresh air cover 122 and the fan cavity.

[0119] In some embodiments, the fresh air module 12 also includes a first purification device (not shown), wherein the first purification device is inserted in the first cavity 100, and the first purification device is located on the rear side of the fresh air volute 120, and the first purification device is used to purify the fresh air entering the fan cavity.

[0120] In some embodiments, when the fresh air module 12 includes a fresh air cover 122 , the first purification device is inserted into the fresh air cover 122 , and the first purification device is used to purify the fresh air entering the fan cavity through the fresh air cover 122 .

[0121] In some embodiments, the fresh air module 12 further includes a flow guide 123 . The flow guide 123 is disposed above the fresh air volute 1120 . The flow guide 123 has a flow guide duct 1230 .

[0122] In some embodiments, the guide member 123 has a front end and a rear end, the front end is provided with a first air outlet 1232, and the rear end is provided with a first air inlet 1231, the first air outlet 1232 and the first air inlet 1231 are connected to the guide air duct 1230, and the first air inlet 1231 is connected to the volute air outlet 1200.

[0123] In some embodiments, the first air outlet 1232 is connected to the fresh air outlet 105, the guide member 123 is inclined relative to the horizontal plane, and the front end of the guide member 123 is located above the rear end of the guide member 123 to form an installation space 124 between the guide member 123 and the casing 10, and the moving mechanism 13 is at least partially arranged in the installation space 124.

[0124] In some embodiments, the motion mechanism 13 is used to drive the door body 14 to move, so as to open or close the heat exchange air outlet 103 and the fresh air outlet 105 at the same time.

[0125] The vertical air conditioner of the present application is adopted, by setting a guide member 123, the first air inlet 1231 at the rear end of the guide member 123 is connected to the volute air outlet 1200, and the first air outlet 1232 at the front end of the guide member 123 is connected to the fresh air outlet 105, thereby guiding the fresh air to flow out from the fresh air outlet 105. At the same time, by making the guide member 123 tilt relative to the horizontal plane, the direction of the fresh air flowing out of the fresh air outlet 105 has a certain angle with the horizontal plane, so that the heat exchange air flowing out of the heat exchange outlet 103 is mixed with the fresh air flowing out of the fresh air outlet 105, realizing the mixing function of the heat exchange air and the mixed air, thereby improving the user experience. In addition, an installation space 124 is formed between the guide member 123 and the casing 10, which are arranged at an angle relative to the horizontal plane. The movement mechanism 13 is arranged in the installation space 124. On the one hand, the internal space of the indoor unit 1 can be reasonably utilized, and the structural arrangement is relatively compact. When the mixing function of heat exchange air and mixed air can be realized (that is, the guide member 123 is arranged at an angle relative to the horizontal plane), the size of the indoor unit 1 of the vertical air conditioner in the height direction X can also be reduced. On the other hand, the movement device is located below the heat exchange air outlet 103 and the fresh air outlet 105, so that the door body 14 driven by the movement mechanism 13 opens or closes the heat exchange air outlet 103 and the fresh air outlet 105 at the same time. Only one set of movement mechanism 13 and door body 14 is required, and there is no need to set two sets of movement mechanisms 13 and door bodies 14 for the heat exchange air outlet 103 and the fresh air outlet 105 respectively. This simplifies the structure of the vertical air conditioner and further reduces the size of the indoor unit 1 of the vertical air conditioner in the height direction X.

[0126] Optionally, the motion mechanism 13 may be partially or completely disposed within the installation space 124. The specific selection may be made based on actual conditions and is not specifically limited in this embodiment. Preferably, the motion mechanism 13 may be completely disposed within the installation space 124 to better utilize the installation space 124 and minimize the size of the indoor unit 1 of the vertical air conditioner in the height direction X.

[0127] Please also refer to Figure 2 and Figure 3 In some embodiments, in the width direction Y of the casing 10 , the width of the heat exchange outlet 103 is the same as the width of the fresh air outlet 105 .

[0128] In this way, on the one hand, the width of the heat exchange air flowing out of the heat exchange outlet 103 and the fresh air flowing out of the fresh air outlet 105 can be roughly the same, so that in the width direction Y of the casing 10, the heat exchange air and the fresh air can be better mixed in different areas, thereby improving the uniformity of the mixing of the heat exchange air and the fresh air. On the other hand, the heat exchange outlet 103 and the fresh air outlet 105 can have better appearance consistency, and from the appearance, the heat exchange outlet 103 and the fresh air outlet 105 form a large outlet, thereby improving the aesthetics of the appearance.

[0129] In this embodiment, the width of the heat exchange outlet 103 is the same as the width of the fresh air outlet 105, which means that the width dimension of the heat exchange outlet 103 is roughly the same as the width dimension of the fresh air outlet 105, and it is not required that the width dimensions of the two are strictly equal, that is, the dimensions of the two are roughly the same within the acceptable error range of assembly tolerance, processing tolerance, etc.

[0130] In the width direction Y of the casing 10 , the width of the casing 10 is d1 , the width of the heat exchange air outlet 103 is d2 , and the width of the fresh air outlet 105 is d3 .

[0131] In some embodiments, the width d2 satisfies: d2≤1 / 2d1.

[0132] In this way, the width of the heat exchange air outlet 103 can be prevented from being too large, resulting in insufficient space in the first cavity 100 of the casing 10 in the width direction Y, affecting the arrangement of other components in the casing 10 (such as the heat exchange volute 11, etc.).

[0133] In some embodiments, the width d2 satisfies: d2 ≥ 1 / 3 d1.

[0134] In this way, the width of the heat exchange air outlet 103 can be made relatively large, thereby increasing the width of the heat exchange air outlet area and meeting the user's demand for an air conditioner with a large air outlet.

[0135] In some embodiments, the width d2 satisfies: 1 / 3d1≤d2≤1 / 2d1. For example, the width d2 may be 1 / 2d1, 5 / 12d1, or 1 / 3d1.

[0136] In this way, the width of the heat exchange air outlet 103 can be avoided from being too large, resulting in insufficient space in the width direction Y of the first cavity 100 of the casing 10, affecting the arrangement of other components in the casing 10 (such as the heat exchange volute 11, etc.). At the same time, the width of the heat exchange air outlet 103 can be made relatively large, thereby increasing the width of the outlet area of ​​the heat exchange air and the fresh air, and meeting the user's demand for air conditioning with a large air outlet.

[0137] In some embodiments, the width d3 satisfies: d3≤1 / 2d1.

[0138] In this way, the width of the fresh air outlet 105 can be prevented from being too large, resulting in insufficient space in the width direction Y between the first cavity 100 and the second cavity 101 of the casing 10, affecting the arrangement of other components in the casing 10 (such as the fresh air volute 120, etc.).

[0139] In some embodiments, the width d3 satisfies: d3 ≥ 1 / 3 d1.

[0140] In this way, the width of the fresh air outlet 105 can be made relatively large, thereby increasing the width of the fresh air outlet area and meeting the user's demand for an air conditioner with a large air outlet.

[0141] In some embodiments, the width d3 satisfies: 1 / 3d1≤d3≤1 / 2d1. For example, the width d3 may be 1 / 2d1, 5 / 12d1, or 1 / 3d1.

[0142] In this way, the width of the fresh air outlet 105 can be avoided from being too large, resulting in insufficient space in the width direction Y between the first cavity 100 and the second cavity 101 of the casing 10, affecting the arrangement of other components in the casing 10 (such as the fresh air volute 120, etc.). At the same time, the width of the fresh air outlet 105 can be made relatively large, thereby increasing the width of the fresh air outlet area and meeting the user's demand for air conditioning with a large air outlet.

[0143] In some embodiments, the housing 10 includes an outer shell 10 a , and a first cavity 100 and a second cavity 101 are formed in the outer shell 10 a .

[0144] In some embodiments, the housing 10 includes a panel seat 10b disposed in the outer shell 10a. The panel seat 10b has a heat exchange outlet 103 and a fresh air outlet 105. An installation space 124 is formed between the guide member 123 and the panel seat 10b.

[0145] The outer shell 10a serves as the appearance structural component of the indoor unit 1, which can shield the internal structure of the indoor unit 1 and improve the aesthetics of the appearance of the indoor unit 1. The panel seat 10b serves as an internal structural component, which is used to form the heat exchange outlet 103 and the fresh air outlet 105, and serves to install components such as the heat exchange volute 11, the motion mechanism 13 and the door body 14.

[0146] Please also refer to Figure 3 and Figure 5 In some embodiments, the panel seat 10b is provided with a mounting portion 106 , which is located below the fresh air outlet 105 , and an installation space 124 is formed between the guide member 123 and the mounting portion 106 .

[0147] An installation space 124 can be formed between the guide member 123 and the installation portion 106 to accommodate the motion mechanism 13 , and the installation portion 106 can provide support for the motion mechanism 13 , facilitating installation of the motion mechanism 13 on the housing 10 .

[0148] Optionally, the mounting portion 106 may be a bracket structure or a plate-shaped structure, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0149] In some embodiments, the casing 10 further includes an air guide plate 10c, which is disposed on the panel seat 10b. The air guide plate 10c extends along the height direction X of the casing 10. In the direction from the front side of the casing 10 toward the rear side of the casing 10, the projection of the air guide plate 10c on the panel seat 10b at least covers the heat exchange outlet 103 and the fresh air outlet 105.

[0150] The air guide plate 10c is rotatably mounted on the panel seat 10b. By rotating the air guide plate 10c, it can simultaneously guide the heat exchange air and the fresh air, thereby changing the outlet angles of the heat exchange air and the fresh air, thereby achieving the air sweeping function of the indoor unit 1. In addition, because the projection of the air guide plate 10c on the panel seat 10b covers the heat exchange air outlet 103 and the fresh air outlet 105, it can to a certain extent block the housing 10 between the heat exchange air outlet 103 and the fresh air outlet 105, making the heat exchange air outlet 103 and the fresh air outlet 105 appear more like a large air outlet, thereby improving the decorative effect of the indoor unit 1.

[0151] In some embodiments, the indoor unit 1 further includes a water receiving tray 15 , which is disposed between the heat exchange volute 11 and the flow guide 123 .

[0152] Since condensation is easily generated on the air guide plate 10c during the process of the heat exchange fan outputting heat exchange air to the heat exchange air outlet 103, a water receiving tray 15 is provided between the heat exchange volute 11 and the guide member 123. The water receiving tray 15 can receive the condensation and prevent the condensation from dripping directly from the air guide plate 10c to the floor, thereby affecting the user experience.

[0153] Optionally, the cross-sectional shape of the air guide 123 can be rectangular, circular, or elliptical, etc., which can be selected according to actual conditions and is not specifically limited in this embodiment. Generally, the cross-sectional shape of the air guide 123 can be matched with the shape of the fresh air outlet 105 to reduce the loss of fresh air volume.

[0154] Please also refer to Figures 6 to 8In some embodiments, the air guide 123 includes a first part 123a and a second part 123b connected to each other, the first part 123a has a first air inlet 1231, the second part 123b has a first air outlet 1232, and the first part 123a and the second part 123b together form a guide air duct 1230; wherein the angle between the first part 123a and the horizontal plane is greater than the angle between the second part 123b and the horizontal plane.

[0155] On the one hand, when the fresh air flows out from the volute air outlet 1200, it usually flows upward. By making the angle between the first part 123a and the horizontal plane greater than the angle between the second part 123b and the horizontal plane, the fresh air passes through the first part 123a and the second part 123b in sequence from the volute air outlet 1200 and then flows out from the fresh air outlet 105, so that the flow direction of the fresh air in the first part 123a is changed from the vertical direction to form a smaller angle with the vertical direction, and then the flow direction of the fresh air in the second part 123b is changed from the smaller angle with the vertical direction to form a larger angle with the vertical direction, which can control the flow direction of the fresh air. The change plays a transitional role, reducing the loss of fresh air flow rate and increasing the flow rate of fresh air flowing out of the fresh air outlet 105. On the other hand, by making the angle between the second part 123b and the horizontal plane relatively small, the size of the guide member 123 in the height direction X of the casing 10 can be reduced, thereby reducing the size of the indoor unit 1 of the vertical air conditioner in the height direction X. On the other hand, due to the angle between the first part 123a and the second part 123b, the capacity of the installation space 124 is relatively large (when the bottom length is the same as the side length, the area of ​​the quadrilateral is larger than that of the triangle), which is conducive to accommodating the motion mechanism 13.

[0156] In some embodiments, the second portion 123b includes a first connecting plate 1233, a second connecting plate 1234, a third connecting plate 1235 and a fourth connecting plate 1236 that are connected end to end in sequence to enclose a first air outlet 1232, and the first connecting plate 1233 is located above the second connecting plate 1234, the third connecting plate 1235 and the fourth connecting plate 1236; the first connecting plate 1233 and the third connecting plate 1235 are inclined relative to the horizontal plane.

[0157] Since the shape of the fresh air outlet 105 is usually rectangular, by setting the second part 123b to the first connecting plate 1233, the second connecting plate 1234, the third connecting plate 1235 and the fourth connecting plate 1236 which are connected end to end in sequence, the shape of the first air outlet 1232 (and the cross-section of the guide air duct 1230) is also rectangular, that is, the first air outlet 1232 matches the shape of the fresh air outlet 105, which can reduce the loss of fresh air volume. By setting the first connecting plate 1233 and the third connecting plate 1235 to be inclined relative to the horizontal plane, the first connecting plate 1233 and the third connecting plate 1235 can guide the flow of fresh air, so that the flow direction of the fresh air when flowing out of the fresh air outlet 105 is inclined relative to the horizontal plane, thereby realizing the mixing of fresh air and heat exchange air.

[0158] Optionally, the first connecting plate 1233, the second connecting plate 1234, the third connecting plate 1235 and the fourth connecting plate 1236 can be integrally formed, for example, the second part 123b is a rectangular pipe, or the first connecting plate 1233, the second connecting plate 1234, the third connecting plate 1235 and the fourth connecting plate 1236 can also be separately provided, for example, the first connecting plate 1233, the second connecting plate 1234, the third connecting plate 1235 and the fourth connecting plate 1236 are respectively independently provided plate structures, and the four plate structures are spliced ​​to form the second part 123b.

[0159] In some embodiments, the first portion 123a also includes four connecting plates connected end to end in sequence. For details, please refer to the structure of the second portion 123b, which will not be described in detail here.

[0160] In some embodiments, the included angle between the first connecting plate 1233 and the horizontal plane is a1, and the included angle a1 satisfies: a1≤40°.

[0161] When the size of the first connecting plate 1233 in the thickness direction Z of the casing 10 remains unchanged, the size of the first connecting plate 1233 in the height direction X of the casing 10 can be made relatively small, thereby making the size of the guide member 123 in the height direction X of the casing 10 relatively small, thereby reducing the size of the indoor unit 1 of the vertical air conditioner in the height direction X.

[0162] In some embodiments, the included angle between the first connecting plate 1233 and the horizontal plane is a1, and the included angle a1 satisfies: a1 ≥ 10°.

[0163] By meeting this condition, the flow direction of the fresh air flowing out of the fresh air outlet 105 after being guided by the first connecting plate 1233 can have a certain angle with the horizontal plane, that is, the flow direction of the fresh air and the flow direction of the heat exchange air can have a certain angle, thereby ensuring a better mixing effect of the fresh air and the heat exchange air.

[0164] In some embodiments, the angle a1 between the first connecting plate 1233 and the horizontal plane satisfies the following relationship: 110°≤a1≤40°. For example, the angle a1 between the first connecting plate 1233 and the horizontal plane can be 10°, 20°, 30°, or 40°.

[0165] When this condition is met, while the size of the first connecting plate 1233 in the thickness direction Z of the casing 10 remains unchanged, the size of the first connecting plate 1233 in the height direction X of the casing 10 can be made relatively small, thereby making the size of the guide member 123 in the height direction X of the casing 10 relatively small, thereby reducing the size of the indoor unit 1 of the vertical air conditioner in the height direction X. At the same time, the flow direction of the fresh air flowing out of the fresh air outlet 105 after being guided by the first connecting plate 1233 can have a certain angle with the horizontal plane, that is, the flow direction of the fresh air and the flow direction of the heat exchange air have a certain angle, thereby ensuring a better mixing effect of the fresh air and the heat exchange air.

[0166] In some embodiments, the included angle between the third connecting plate 1235 and the horizontal plane is a2, and the included angle a2 satisfies: a2≤40°.

[0167] When this condition is met, while the size of the third connecting plate 1235 in the thickness direction Z of the casing 10 remains unchanged, the size of the third connecting plate 1235 in the height direction X of the casing 10 can be made relatively small, thereby making the size of the guide member 123 in the height direction X of the casing 10 relatively small, thereby reducing the size of the indoor unit 1 of the vertical air conditioner in the height direction X.

[0168] In some embodiments, the angle between the third connecting plate 1235 and the horizontal plane is a2, and the angle a2 satisfies: a2 ≥ 10°.

[0169] By meeting this condition, the flow direction of the fresh air flowing out of the fresh air outlet 105 after being guided by the third connecting plate 1235 can have a certain angle with the horizontal plane, that is, the flow direction of the fresh air and the flow direction of the heat exchange air can have a certain angle, thereby ensuring a better mixing effect of the fresh air and the heat exchange air.

[0170] In some embodiments, the angle a2 between the third connecting plate 1235 and the horizontal plane satisfies the following conditions: 110°≤a2≤40°. For example, the angle a2 between the third connecting plate 1235 and the horizontal plane can be 10°, 20°, 30°, or 40°.

[0171] When this condition is met, under the condition that the size of the third connecting plate 1235 in the thickness direction Z of the casing 10 remains unchanged, the size of the third connecting plate 1235 in the height direction X of the casing 10 can be made relatively small, thereby making the size of the guide member 123 in the height direction X of the casing 10 relatively small, thereby reducing the size of the indoor unit 1 of the vertical air conditioner in the height direction X. At the same time, the flow direction of the fresh air flowing out of the fresh air outlet 105 after being guided by the third connecting plate 1235 can have a certain angle with the horizontal plane, that is, the flow direction of the fresh air and the flow direction of the heat exchange air have a certain angle, thereby ensuring that the fresh air and the heat exchange air have a better mixing effect.

[0172] In some embodiments, the angle a1 between the first connecting plate 1233 and the horizontal plane is equal to the angle a2 between the third connecting plate 1235 and the horizontal plane. This allows the first connecting plate 1233 and the third connecting plate 1235 to have a more consistent effect on guiding the fresh air, thereby improving the consistency of the flow direction of the fresh air flowing out of the first air outlet 1232.

[0173] Since the fresh air is mainly blocked by the first connecting plate 1233 of the second part 123b and changes its flow direction during the process of flowing from the first part 123a to the second part 123b, the fresh air is mainly concentrated in the upper half of the first part 123a, that is, the fresh air is concentrated in the area close to the first connecting plate 1233, resulting in more serious vortex phenomenon of the fresh air at the angle between the first connecting plate 1233 and the second connecting plate 1234, and at the angle between the first connecting plate 1233 and the fourth connecting plate 1236, which in turn causes the guide member 123 to easily produce abnormal noise at this position, affecting the service life of the guide member 123 and the user experience.

[0174] In some embodiments, a transition portion 1237 is provided between the first connecting plate 1233 and the second connecting plate 1234 .

[0175] In this way, the transition portion 1237 can reduce the vortex phenomenon of the fresh air at the angle between the first connecting plate 1233 and the second connecting plate 1234, thereby reducing the abnormal noise phenomenon of the guide member 123 at this position, improving the service life of the guide member 123, and affecting the user's experience. At the same time, the transition portion 1237 can also reduce the stress concentration phenomenon at the connection between the first connecting plate 1233 and the second connecting plate 1234, and improve the structural strength of the guide member 123.

[0176] In some embodiments, a transition portion 1237 is provided between the first connecting plate 1233 and the fourth connecting plate 1236 .

[0177] In this way, the transition portion 1237 can reduce the vortex phenomenon of the fresh air at the angle between the first connecting plate 1233 and the fourth connecting plate 1236, thereby reducing the abnormal noise phenomenon of the guide member 123 at this position, improving the service life of the guide member 123, and affecting the user's experience. At the same time, the transition portion 1237 can also reduce the stress concentration phenomenon at the connection between the first connecting plate 1233 and the fourth connecting plate 1236, and improve the structural strength of the guide member 123.

[0178] In some embodiments, a transition portion 1237 may be provided between the first connecting plate 1233 and the second connecting plate 1234 and between the first connecting plate 1233 and the fourth connecting plate 1236, so that the abnormal noise phenomenon at the two positions on the second part 123b that are prone to abnormal noise can be resolved, thereby better reducing the overall abnormal noise phenomenon of the guide member 123.

[0179] Optionally, the transition portion 1237 may be an arc transition portion 1237 (eg, a rounded corner) or a triangular transition portion 1237 (eg, a chamfered corner), which may be selected based on actual conditions and is not specifically limited in this embodiment.

[0180] Exemplarily, the transition portion 1237 can be set as an arc transition portion 1237, which can make the flow of fresh air more uniform at the angle between the first connecting plate 1233 and the second connecting plate 1234 and at the angle between the first connecting plate 1233 and the fourth connecting plate 1236, further reducing the vortex phenomenon of the fresh air at this position, thereby further reducing the abnormal noise phenomenon of the guide member 123 at this position.

[0181] In some embodiments, the radius of the transition portion 1237 is R, and the radius R satisfies: R≥15 mm.

[0182] In this way, the transition portion 1237 can have a sufficient size to make the transition at the angle between the first connecting plate 1233 and the second connecting plate 1234 smoother, thereby ensuring that the transition portion 1237 can reduce the vortex phenomenon of the fresh air.

[0183] In some embodiments, the radius of the transition portion 1237 is R, and the radius R satisfies: R≤25 mm.

[0184] In this way, it is possible to avoid the size of the transition portion 1237 being too large, which would significantly affect the size of the first air outlet 1232 , thereby ensuring the amount of fresh air flowing out of the first air outlet 1232 .

[0185] In some embodiments, the radius of the transition portion 1237 is R, and the radius R satisfies: 15 mm ≤ R ≤ 25 mm. For example, the radius R of the transition portion 1237 can be 15 mm, 20°, 30°, or 25 mm.

[0186] In this way, the transition portion 1237 can have a sufficient size so that the transition at the angle between the first connecting plate 1233 and the second connecting plate 1234 is smoother, thereby ensuring that the transition portion 1237 reduces the vortex phenomenon of the fresh air. At the same time, it can avoid the size of the transition portion 1237 being too large, which greatly affects the size of the first air outlet 1232, thereby ensuring the amount of fresh air flowing out of the first air outlet 1232.

[0187] In some embodiments, the air guide 123 is provided with a first connecting member 1238, which is connected to the water receiving tray 15. Thus, when assembling the indoor unit 1, the air guide 123 can be first connected and fixed to the water receiving tray 15, and then the air guide 123 and the water receiving tray 15 can be installed together into the casing 10 (usually, the air guide 123 is already assembled with the fresh air volute 120). This can facilitate the installation of components within the casing 10 and reduce the number of assembly steps for the indoor unit 1.

[0188] Optionally, the first connecting member 1238 may be a plate-shaped structure or a block-shaped structure, etc., which can be selected according to actual conditions and is not specifically limited in this embodiment.

[0189] See also Figure 2 In some embodiments, in the height direction X of the housing 10 , the distance between the heat exchange outlet 103 and the fresh air outlet 105 is L, and the distance L satisfies: L≤80 mm.

[0190] When this relationship is satisfied, the distance between the heat exchange outlet 103 and the fresh air outlet 105 can be made relatively small, making it easier to mix the heat exchange air and the fresh air. At the same time, the heat exchange outlet 103 and the fresh air outlet 105 look more like a large outlet, thereby improving the aesthetics of the indoor unit 1.

[0191] In some embodiments, in the height direction X of the housing 10 , the distance between the heat exchange outlet 103 and the fresh air outlet 105 is L, and the distance L satisfies: L ≥ 60 mm.

[0192] When this relationship is satisfied, sufficient space is ensured within the first chamber 100 between the heat exchange outlet 103 and the fresh air outlet 105 to accommodate structures such as the water receiving pan 15 and the bottom shell of the heat exchange volute 11. Furthermore, sufficient space is ensured for the first connector 1238, allowing the flow guide 123 to be directly assembled with the water receiving pan 15.

[0193] In some embodiments, the distance L between the heat exchange outlet 103 and the fresh air outlet 105 in the height direction X of the housing 10 satisfies the following: 60 mm ≤ L ≤ 80 mm. For example, the distance L between the heat exchange outlet 103 and the fresh air outlet 105 can be 60 mm, 65 mm, 70 mm, 75 mm, or 80 mm, etc., and can be selected based on actual conditions and is not specifically limited in this embodiment.

[0194] This reduces the distance between the heat exchange outlet 103 and the fresh air outlet 105, making it easier to mix the heated air and the fresh air. Furthermore, the heat exchange outlet 103 and the fresh air outlet 105 appear to be one large outlet, improving the aesthetics of the indoor unit 1. Furthermore, sufficient space is ensured within the first cavity 100 between the heat exchange outlet 103 and the fresh air outlet 105 to accommodate structures such as the water receiving tray 15 and the bottom shell of the heat exchange volute 11. Furthermore, sufficient space is ensured for the first connector 1238, allowing the flow guide 123 to be directly assembled with the water receiving tray 15.

[0195] Please also refer to Figure 9 and Figure 10 In some embodiments, the fresh air module 12 further includes an air outlet grille 125 , which is disposed at the first air outlet 1232 . The air outlet grille 125 includes a plurality of grille bars 1250 spaced apart along a height direction X of the housing 10 .

[0196] The air outlet grille 125 includes a plurality of grille bars 1250 , which can guide the fresh air so that the fresh air flowing out of the first air outlet 1232 flows more evenly.

[0197] Optionally, the air outlet grille 125 may be a separately provided component, or the air outlet grille 125 may be integrated with the panel seat 10b. The specific selection may be made according to actual conditions and is not specifically limited in this embodiment.

[0198] In some embodiments, the grille bars 1250 are tilted relative to the horizontal plane.

[0199] Therefore, the grille bars 1250 can also guide the fresh air, further ensuring that there is a certain angle between the fresh air flowing out of the first air outlet 1232 and the horizontal plane, thereby improving the mixing effect of the fresh air and the heat exchange air.

[0200] In some embodiments, the included angle between the grille bar 1250 and the horizontal plane is a3, and the included angle a3 satisfies: a3≤40°.

[0201] In this way, the blocking area of ​​the grille bars 1250 to the fresh air can be reduced, thereby preventing the grille bars 1250 from excessively affecting the fresh air output volume.

[0202] In some embodiments, the included angle between the grille bar 1250 and the horizontal plane is a3, and the included angle a3 satisfies: a3 ≥ 10°.

[0203] In this way, it can be ensured that the flow direction of the fresh air flowing out of the fresh air outlet 105 through the grille bars 1250 has a certain angle with the horizontal plane, that is, the flow direction of the fresh air and the flow direction of the heat exchange air have a certain angle, thereby ensuring that the fresh air and the heat exchange air have a better mixing effect.

[0204] In some embodiments, the angle a3 between the grille bars 1250 and the horizontal plane satisfies the following conditions: 10°≤a3≤40°. For example, the angle a3 between the grille bars 1250 and the horizontal plane can be 10°, 20°, 30°, or 40°.

[0205] In this way, the blocking area of ​​the grille bars 1250 to the fresh air can be reduced, and the grille bars 1250 can be prevented from affecting the fresh air output too much. At the same time, it can ensure that the flow direction of the fresh air flowing out from the fresh air outlet 105 through the grille bars 1250 has a certain angle with the horizontal plane, that is, the flow direction of the fresh air and the flow direction of the heat exchange air have a certain angle, thereby ensuring that the fresh air and the heat exchange air have a better mixing effect.

[0206] In some embodiments, the angle a3 between the grille bar 1250 and the horizontal plane, the angle a1 between the first connecting plate 1233 and the horizontal plane, and the angle a2 between the third connecting plate 1235 and the horizontal plane are all equal.

[0207] In this way, the grille bars 1250 , the first connecting plate 1233 and the third connecting plate 1235 can have better consistency in guiding the fresh air, thereby improving the consistency of the flow direction of the fresh air flowing out of the first air outlet 1232 .
