Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, and more particularly to an air conditioner. Background Technology

[0002] Air conditioner products mainly consist of indoor units and outdoor units. Indoor units are typically used for functions such as cooling, heating, and ventilation in indoor environments.

[0003] In related technologies, indoor units typically include a fresh air function. This means the indoor unit can improve indoor air quality by expelling stale indoor air and drawing in fresh outdoor air. To enhance user experience, the fresh air outlet is usually positioned near the cool air outlet, allowing for air mixing and improving the unit's airflow. However, because the fresh air is drawn in from the outside, it is warmer and contains more moisture. When the fresh air duct and cool air duct are positioned close together, they can easily mix as they exit from the outer edges of the respective ducts. This causes moisture in the fresh air to condense at the outer edges of either duct, resulting in condensation and negatively impacting the user experience. Utility Model Content

[0004] This application discloses an air conditioner to improve the problem of condensation easily occurring at the outer edge of the air guide structure when fresh air and cool air are discharged from the air guide structure.

[0005] To achieve the above objectives, this application discloses an air conditioner, comprising:

[0006] Indoor unit;

[0007] The indoor unit includes:

[0008] The housing has an inner cavity and an indoor air outlet communicating with the inner cavity;

[0009] The fresh air structure is disposed in the inner cavity;

[0010] A cooling air structure is provided in the inner cavity;

[0011] An air guiding structure is provided at the indoor air outlet. The air guiding structure forms a fresh air guiding channel and a cold air guiding channel. The fresh air guiding channel is connected to the fresh air structure, and the cold air guiding channel is connected to the cold air structure.

[0012] The air guiding structure includes:

[0013] The first air guide is constructed in an annular shape, and the inner annular side of the first air guide forms the cold air guiding channel.

[0014] The second air guide is constructed as a ring, and the second air guide is arranged around the outer periphery of the first air guide, and the second air guide is spaced apart from the first air guide.

[0015] The first air guide component includes:

[0016] A first ring portion, disposed at the indoor air outlet and extending along the depth direction of the housing towards the inner cavity, the first ring portion comprising:

[0017] On the first inner ring side, the cold air guiding channel is constructed.

[0018] On the first outer ring side, the second air guide is arranged around the outer periphery of the first outer ring side and spaced apart from the first outer ring side, so as to construct the fresh air guide channel between the two.

[0019] The second ring is connected to the end of the first ring away from the inner cavity. The second ring extends in a direction toward the second air guide and the extension direction of the second ring is inclined relative to the depth direction of the housing. The second ring is configured to allow the fresh air guide channel to discharge air along the extension direction of the second ring, so that the discharge direction of the fresh air guide channel forms an angle with the discharge direction of the cold air guide channel.

[0020] In the air guiding structure of the indoor unit of this application, the air guiding structure includes a first air guide and a second air guide. The second air guide is arranged around the outer periphery of the first air guide, thereby constructing a cold air guiding channel and a fresh air guiding channel on the first air guide and the second air guide, respectively. The fresh air guiding channel is constructed through the first outer ring side of the first ring portion of the first air guide and the inner ring side of the second air guide. Thus, through this circumferentially enclosing design of the fresh air guiding channel and the cold air guiding channel, the fresh air and cold air of the air conditioner of this application can be mixed and blown, achieving a mixed air effect. Based on achieving the mixed air effect of the air conditioner, this application further considers that: the second ring portion of the first air guide is connected to the first ring portion, and the extension direction of the second ring portion is inclined relative to the depth direction of the casing, which makes the extension direction of the second ring portion form an angle with the extension direction of the first ring portion. Since the second ring portion extends towards the second air guide, when fresh air is discharged, the fresh air will blow onto the second ring portion, and the fresh air will be blown along the extension direction of the second ring portion. In this way, when fresh air is discharged from the fresh air duct, the direction of the fresh air discharge forms an angle with the direction of the cold air discharge from the first inner ring side. The fresh air and the cold air are blown out in different directions, avoiding direct mixing of fresh air and cold air when they are discharged. Instead, the circumferential design of the first and second air guides allows the fresh air and cold air to mix after they are blown away from the indoor air outlet. This prevents condensation caused by mixing of air at the outer edge of the fresh air duct or the outer edge of the cold air duct.

[0021] As some alternative implementations, the extension direction of the second ring forms an angle α with the depth direction of the housing, wherein α is 40°-70°.

[0022] When setting the extension direction of the second ring, on the one hand, it is necessary to consider that the angle α between the second ring and the depth direction of the casing should not be too small. If α < 40°, the angle between the air outlet direction of the fresh air and the air outlet direction of the cold air is small. This results in the fresh air and the cold air being relatively close to each other after they exit from the fresh air guide channel and the cold air guide channel, respectively. This makes it easy for the fresh air and the cold air to mix at the position near the fresh air guide channel and the cold air guide channel. This may also cause condensation to occur at the outer edge of the fresh air guide channel and the outer edge of the cold air guide channel.

[0023] On the other hand, it is also necessary to consider that the angle α between the second ring and the depth direction of the casing should not be too large. If α > 70°, the extension direction of the second ring is close to the width direction of the casing. This may cause the second ring to block the fresh air guide channel, which may not only make the outlet of the fresh air guide channel smaller, but may also cause the fresh air to come into contact with the second ring, resulting in fresh air return, and thus affecting the effective air outlet of the fresh air.

[0024] Therefore, this application controls the range of α to 40°-70°, which can prevent fresh air and cold air from mixing at the outer edge of the fresh air guide channel and the outer edge of the cold air guide channel, and also avoid the second ring from blocking the fresh air guide channel, thereby affecting the effective air outlet of fresh air.

[0025] As some alternative implementations, the second ring portion includes:

[0026] The second inner ring side is connected to the first inner ring side, and the connection between the second inner ring side and the first inner ring side forms the cold air outlet of the cold air guide channel.

[0027] The second outer ring side is connected to the first outer ring side;

[0028] The second air guide includes:

[0029] The third ring is located at the indoor air outlet and extends towards the inner cavity along the depth direction of the casing. The third ring is arranged around the outer periphery of the first outer ring side to form the fresh air guide channel together with the first outer ring side.

[0030] The fourth ring is connected to the side of the third ring away from the inner cavity. The fourth ring is arranged around the outer periphery of the second outer ring and extends in an extension direction parallel to the second ring. The fourth ring is configured to extend the fresh air guide channel. The end of the fourth ring away from the third ring and the end of the second outer ring away from the first outer ring together form the fresh air outlet of the fresh air guide channel.

[0031] In this application, the second air guide component is provided with a third ring and a fourth ring. The inner ring side of the third ring and the first outer ring side form a fresh air guiding channel. The fourth ring and the second outer ring side are used to extend the fresh air guiding channel, so that the fresh air outlet is located at the end of the fourth ring and the second outer ring side away from the first outer ring side. In this way, by extending the outlet position of the fresh air away from the cold air outlet, it is beneficial to avoid the mixing of fresh air and cold air at their respective outlets.

[0032] As some alternative implementations, the extending direction of the fourth ring portion forms an angle β with the extending direction of the third ring portion, the angle β being 40°-70°.

[0033] Because the fourth ring is parallel to the extension direction of the second ring, and the extension directions of the third and fourth rings form an angle β, this creates a bend in the fresh air guide channel. On one hand, if β < 40°, meaning the extension direction of the fourth ring is closer to the depth direction of the casing, the fresh air outlet may be close to the cold air, causing condensation due to air mixing at the fresh air outlet or cold air outlet. On the other hand, if β > 70°, meaning the extension direction of the fourth ring is closer to the width direction of the casing, most of the fresh air may be blown out along the width direction of the casing. This means that once the fresh air is blown out and away from the indoor air outlet, it may be difficult to mix with the cold air, affecting the mixing effect of the fresh air and cold air in the indoor unit.

[0034] Therefore, this application controls the included angle β to a range of about 40°-70°, which can not only avoid the mixing of fresh air and cold air near the fresh air outlet and cold air outlet, but also prevent the fresh air and cold air from being unable to effectively mix after being blown out of the indoor air outlet.

[0035] As some alternative implementations, the first ring portion is formed with a first cavity, the first cavity being isolated from the fresh air guide channel and the cold air guide channel, and the first cavity being configured to reduce heat transfer between the first ring portion and the third ring portion.

[0036] This application not only considers the possibility of condensation caused by the mixing of fresh air and cold air at the fresh air outlet and cold air outlet, but also the possibility that the low temperature of the cold air guide channel may cool the fresh air guide channel, potentially causing water vapor in the fresh air to condense within the fresh air guide channel. To address this, this application forms a first cavity in the first ring section to isolate the fresh air guide channel from the other sections, thereby reducing heat transfer between the first and third ring sections. This reduces the impact of the low temperature in the cold air guide channel on the fresh air guide channel, effectively preventing condensation from forming in the fresh air guide channel.

[0037] As some alternative implementations, the first ring portion includes a main ring portion and an extended ring portion. The main ring portion has a first inner ring side, and the extended ring portion is integrally formed on the main ring portion. The extended ring portion has a first outer ring side, and the extended ring portion is spaced apart from the first outer ring side along the width direction of the housing, so that the first cavity is formed between the extended ring portion and the main ring portion.

[0038] The first ring is located on the side closest to the inner cavity. When cold air is emitted from the first ring, the temperature of the inner ring side is lower. By configuring the first ring as a main ring and an outer ring, and using the space between the outer ring and the main ring to form a first cavity inside the first ring, heat transfer between the inner and outer ring sides can be reduced, preventing condensation of moisture in the fresh air in the fresh air guide channel. Furthermore, the main ring and the outer ring can be integrally formed, preventing gaps in the first ring that could cause airflow leakage between the fresh air guide channel and the cold air guide channel.

[0039] As some alternative implementations, the outer periphery of the second ring portion is provided with a second cavity, the second cavity being isolated from the fresh air outlet and the cold air outlet, and the second cavity being configured to reduce heat transfer between the second ring portion and the fourth ring portion.

[0040] Because the second ring is located near both the fresh air outlet and the cold air outlet, condensation can easily occur at the second ring due to the mixing of fresh air and cold air. This application provides a second cavity on the outer periphery of the second ring to reduce heat transfer between the second and fourth rings, preventing moisture in the fresh air from condensing on the second outer ring side of the fourth or second ring before it is expelled.

[0041] As some optional implementations, the air guiding structure further includes:

[0042] A heat insulation element is disposed around the outer periphery of the second outer ring side, and the heat insulation element is spaced apart from the second outer ring side to form the second cavity.

[0043] A heat insulation element is also provided around the outer periphery of the second ring portion. The heat insulation element is spaced apart from the second outer ring side to reduce heat transfer between the second ring portion and the fourth ring portion.

[0044] In addition, because the second ring is located closer to the external environment, it is not only prone to condensation but also easily accumulates dust, mold, and other contaminants. Therefore, a separate heat insulation component is installed on the second ring to form a second cavity, allowing the heat insulation component to be easily removed for cleaning, thus improving the convenience of cleaning the indoor unit for users.

[0045] As some alternative implementations, the second outer ring side is provided with:

[0046] The abutting portion protrudes from the second outer ring side along the width direction of the housing, and the abutting portion is located on the second outer ring side and is disposed away from the first ring portion. The abutting portion abuts against the heat insulation member, so that the heat insulation member is spaced apart from the second outer ring side.

[0047] The supporting portion is provided at intervals from the abutting portion along the depth direction of the housing. The supporting portion is located on the second outer ring side and is provided near the first ring portion. The supporting portion is configured to support the heat insulation member so that the heat insulation member can be detachably connected to the second outer ring side.

[0048] When the heat insulation component is installed on the second outer ring side, one surface of the heat insulation component abuts against the abutting part, thus separating the heat insulation component from the second outer ring side. Simultaneously, the supporting part supports the other surface of the heat insulation component, locking its position and preventing it from falling off the second outer ring side. This application first uses the abutting part to position the heat insulation component on the second outer ring side, forming a second cavity between the heat insulation component and the second outer ring side. Then, the supporting part supports the heat insulation component, preventing it from falling off the second outer ring side. In this way, the heat insulation component can be positioned and installed on the second outer ring side while also achieving stable installation and preventing it from falling off.

[0049] As some alternative implementations, the indoor air outlet is configured as a circle, and both the first air guide and the second air guide are configured as annular.

[0050] When the indoor air outlet is constructed in a circular shape, the first and second air guides can be constructed in annular shapes to facilitate their installation. This annular construction allows for the formation of vortices between the fresh air and cool air outlets, effectively utilizing aerodynamic design and promoting efficient mixing of fresh and cool air after exiting the fresh air and cool air ducts.

[0051] Compared with the prior art, this application has at least the following beneficial effects:

[0052] In the air guiding structure of the indoor unit of this application, the air guiding structure includes a first air guide and a second air guide. The second air guide is arranged around the outer periphery of the first air guide, thereby constructing a cold air guiding channel and a fresh air guiding channel on the first air guide and the second air guide, respectively. The fresh air guiding channel is constructed through the first outer ring side of the first ring portion of the first air guide and the inner ring side of the second air guide. Thus, through this circumferentially enclosing design of the fresh air guiding channel and the cold air guiding channel, the fresh air and cold air of the air conditioner of this application can be mixed and blown, achieving a mixed air effect. Based on achieving the mixed air effect of the air conditioner, this application further considers that: the second ring portion of the first air guide is connected to the first ring portion, and the extension direction of the second ring portion is inclined relative to the depth direction of the casing, which makes the extension direction of the second ring portion form an angle with the extension direction of the first ring portion. Since the second ring portion extends towards the second air guide, when fresh air is discharged, the fresh air will blow onto the second ring portion, and the fresh air will be blown along the extension direction of the second ring portion. In this way, when fresh air is discharged from the fresh air duct, the direction of the fresh air discharge forms an angle with the direction of the cold air discharge from the first inner ring side. The fresh air and the cold air are blown out in different directions, avoiding direct mixing of fresh air and cold air when they are discharged. Instead, the circumferential design of the first and second air guides allows the fresh air and cold air to mix after they are blown away from the indoor air outlet. This prevents condensation caused by mixing of air at the outer edge of the fresh air duct or the outer edge of the cold air duct. Attached Figure Description

[0066] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0067] In this application, the terms "upper," "lower," "front," "rear," "inner," "outer," and "middle," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0068] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0069] Furthermore, the terms "installation," "setup," "equipped with," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0070] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (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, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0071] Air conditioner products mainly consist of indoor units and outdoor units. Indoor units are typically used for functions such as cooling, heating, and ventilation in indoor environments.

[0072] In related technologies, indoor units typically include a fresh air function. This means the indoor unit can improve indoor air quality by simultaneously exhausting stale indoor air and drawing in fresh outdoor air. For example, a fresh air fan can be used to draw in fresh outdoor air, thus improving indoor air quality. In these technologies, to enhance the user experience, the fresh air outlet is usually positioned near the cool air outlet, allowing for air mixing and improving the unit's airflow efficiency. However, since the fresh air is drawn in from the outside, it is warmer and contains more moisture. Therefore, if the fresh air duct and the cool air duct are positioned close together—for example, side-by-side or surrounding the cool air duct—the fresh air duct may not be effective. Because the fresh air duct and the cold air duct are located too close together, the fresh air and cold air tend to mix directly when they exit from the outer edges of the fresh air duct and the cold air duct, respectively. The cold air that just exits the cavity is at a lower temperature, which makes it easy for moisture in the fresh air to adhere to and condense at the outer edges of the fresh air duct or the cold air duct, resulting in condensation. When the condensate drips from the indoor air outlet, it can cause indoor dampness and affect the user experience.

[0073] Based on this, this application provides an air conditioner that, by designing the outlet angles of the fresh air guide channel and the cold air guide channel, avoids the mixing of fresh air and cold air at the outer edges of the fresh air guide channel and the cold air guide channel during air outlet, thus preventing condensation from forming at the outer edges of the fresh air guide channel and the cold air guide channel. Furthermore, this application also provides a cavity at the junction of the fresh air guide channel and the cold air guide channel, using the cavity to reduce heat transfer between the two channels, preventing moisture in the fresh air from condensing in the fresh air guide channel and causing condensation.

[0074] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0075] Please see Figure 1 This application discloses an air conditioner, which may include an indoor unit 100 and an outdoor unit (not shown). The indoor unit 100 is usually installed indoors and exchanges heat with indoor air through an indoor evaporator. The outdoor unit is installed outdoors and connected to the indoor unit 100. It mainly compresses the refrigerant and delivers it to the indoor unit to achieve a cooling or heating effect.

[0076] Please see Figure 2 In some embodiments, the indoor unit 100 includes a housing 1, the housing 1 having an inner cavity 1a, and the housing 1 having an indoor air inlet 1b and an indoor air outlet 1c, the indoor air outlet 1c and the indoor air inlet 1b being connected to the inner cavity 1a.

[0077] In some embodiments, the indoor unit may be a wall-mounted indoor unit or a floor-standing indoor unit.

[0078] For example, taking a vertical indoor unit as an example, the casing has a depth direction, a width direction, and a height direction, such as... Figure 1 In the example, X indicates the width of the housing, Y indicates the depth of the housing, and Z indicates the height of the housing.

[0079] In some embodiments, the indoor unit 100 includes a cooling air structure (not shown).

[0080] In some embodiments, the cooling air structure is located in the inner cavity 1a.

[0081] In some embodiments, the cooling air structure includes a heat exchange volute (not shown).

[0082] In some embodiments, the cooling structure includes an indoor heat exchanger (not shown).

[0083] In some embodiments, an indoor heat exchanger is disposed inside a heat exchange volute and is used to exchange heat with indoor air entering the heat exchange volute.

[0084] In some embodiments, the cooling structure includes a heat exchange fan (not shown).

[0085] In some embodiments, the heat exchange fan is disposed in the heat exchange volute and is located in front of the indoor heat exchanger. The heat exchange fan is used to provide power for the flow of indoor air.

[0086] Driven by the heat exchange fan, indoor air enters the heat exchange volute through the air inlet 1b of the heat exchange chamber and exchanges heat with the indoor heat exchanger. After heat exchange, the indoor air is discharged from the heat exchange volute through the heat exchange outlet and then discharged from the indoor air outlet 1c.

[0087] In other words, the heat exchange volute is used to house the indoor heat exchanger and the heat exchange fan, and to provide an air cavity for the indoor heat exchanger and the heat exchange fan.

[0088] In some embodiments, the cooling structure includes a fan (not shown), which is disposed in the inner cavity 1a along the height direction of the housing 1, that is, the rotation axis of the fan is perpendicular to the horizontal plane. The fan can be driven by a motor. When the vertical air conditioner is working, the motor drives the fan to rotate. The outside air first blows through the indoor heat exchanger and exchanges heat with the indoor heat exchanger before entering the fan and being blown out from the indoor air outlet under the action of the fan.

[0089] In some embodiments, the indoor unit 100 includes a fresh air structure 2, which is disposed in the inner cavity 1a.

[0090] In some embodiments, the fresh air structure 2 includes a fresh air unit configured to draw fresh outdoor air into the indoor unit 100.

[0091] In some embodiments, the fresh air structure 2 includes a filter (not shown) for filtering impurities in the fresh air drawn into the indoor unit 100 by the fresh air unit to ensure that the fresh air is clean and hygienic.

[0092] In some embodiments, the fresh air structure 2 includes an exhaust fan (not shown) for exhausting stale indoor air to the outside.

[0093] In some embodiments, the outdoor unit of an air conditioner includes an outer casing, an outdoor heat exchanger, and an outdoor fan.

[0094] In some embodiments, an outdoor accommodating space is provided inside the outer shell, wherein the outdoor fan and the outdoor heat exchanger are located within the outdoor accommodating space.

[0095] In some embodiments, the outer shell of the chamber is provided with an outdoor air inlet and an outdoor air outlet, both of which are connected to the outdoor containment space. The outdoor air inlet is used to introduce outdoor air into the outdoor containment space, and the outdoor air outlet is used to exhaust air from the outdoor containment space to the outside of the outdoor containment space.

[0096] In some embodiments, the rotation of the outdoor fan causes outdoor air to enter the outdoor containment space through the outdoor air inlet and exchange heat with the outdoor heat exchanger. The outdoor air after heat exchange flows out of the outdoor containment space through the outdoor air outlet.

[0097] In some embodiments, the outdoor unit of the air conditioner further includes a compressor and a throttling device, both of which are located within the outdoor containment space.

[0098] In some embodiments, an air conditioner performs a refrigeration cycle by 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 supplying refrigerant to conditioned and heat-exchanged air.

[0099] In some embodiments, the compressor compresses the refrigerant gas in a low-temperature, low-pressure state and discharges it into a high-temperature, high-pressure state. The discharged refrigerant gas flows into the condenser.

[0100] 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.

[0101] In some embodiments, the throttling device causes the high-temperature, high-pressure liquid refrigerant condensed in the condenser to expand into a low-pressure liquid refrigerant.

[0102] In some embodiments, the evaporator evaporates the refrigerant that expands in the throttling device and returns the refrigerant gas, which is in a low-temperature and low-pressure state, to the compressor.

[0103] In some embodiments, the evaporator achieves a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material to be cooled. Throughout the cycle, the temperature of the indoor space can be regulated.

[0104] In some embodiments, of 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 air conditioner is used as a heater in heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in cooling mode.

[0105] Please see also Figures 3 to 5 In some embodiments, the indoor unit 100 includes an air guide structure 3, which is located at the indoor air outlet 1c. The air guide structure 3 forms a cold air guide channel 3a and a fresh air guide channel 3b. The fresh air guide channel 3b is connected to the fresh air structure 2, and the cold air guide channel 3a is connected to the cold air structure.

[0106] In the air guiding structure 3 disclosed in this application, the cold air structure and the fresh air structure 2 are connected through one air guiding structure 3, thereby realizing the mixed air output of cold air and fresh air, which is beneficial to improving the freshness of the air output from the indoor unit 100.

[0107] In some embodiments, the air guiding structure 3 includes a first air guiding member 31, and a cold air guiding channel 3a is formed on the inner ring side of the first air guiding member 31.

[0108] For example, when the first air guide 31 is configured as an annular shape, a channel for guiding cold air can be formed on the inner ring side of the first air guide 31, and the cold air blown out from the inner cavity 1a can be blown out along the inner ring side of the first air guide 31 to form an effective air guide for cold air.

[0109] In some embodiments, the air guiding structure 3 includes a second air guiding member 32, which is configured as an annular ring. The second air guiding member 32 is arranged around the outer periphery of the first air guiding member 31, and the second air guiding member 32 and the first air guiding member 31 are spaced apart.

[0110] For example, when the annular second air guide 32 is arranged around the outer periphery of the first air guide 31 and the second air guide 32 is spaced apart from the first air guide 31, the fresh air guide channel 3b is formed by utilizing the outer ring side of the first air guide 31 and the inner ring side of the second air guide 32, so that the fresh air guide channel 3b and the cold air guide channel 3a are arranged adjacent to each other, which is beneficial for fresh air and cold air to mix after moving away from the indoor air outlet 1c.

[0111] In some embodiments, the first air guide 31 is detachably connected to the second air guide 32, and the second air guide 32 is detachably connected to the housing 1.

[0112] In this way, when the first air guide 31 and the second air guide 32 need to be removed from the housing 1 for cleaning, the second air guide 32 can be removed first, and then the first air guide 31 can be removed from the second air guide 32. Alternatively, the first air guide 31 can be removed separately for cleaning. Thus, the first air guide 31 or the second air guide 32 can be selectively disassembled and cleaned, making it convenient for users to clean the air guide structure 3.

[0113] It is understood that the detachable connection of the second air guide 32 relative to the housing 1 includes, but is not limited to, the connection between hooks and hooks, the connection between hooks and grooves, etc., and the detachable connection of the first air guide 31 relative to the second air guide 32 includes, but is not limited to, the connection between hooks and hooks, the connection between hooks and grooves, etc.

[0114] Please continue reading Figures 5 to 9 In some embodiments, the first air guide 31 includes a first ring portion 311, which is disposed at the indoor air outlet 1c and extends toward the inner cavity 1a along the depth direction of the housing 1.

[0115] Optionally, the first ring portion 311 includes a first inner ring side 311a and a first outer ring side 311b. The first inner ring side 311a forms a cold air guiding channel 3a. The second air guiding member 32 is arranged around the outer periphery of the first outer ring side 311b and spaced apart from the first outer ring side 311b to form a fresh air guiding channel 3b between the two.

[0116] In some embodiments, the first air guide 31 includes a second ring portion 312 connected to the end of the first ring portion 311 away from the inner cavity 1a. The second ring portion 312 extends in a direction toward the second air guide 32, and the extension direction of the second ring portion 312 is inclined relative to the depth direction of the housing 1. The second ring portion 312 is configured to allow the fresh air guide channel 3b to discharge air along the extension direction of the second ring portion 312, so that the air discharge direction of the fresh air guide channel 3b forms an angle with the air discharge direction of the cold air guide channel 3a.

[0117] In the air guiding structure 3 of the indoor unit 100 of this application, the second air guiding member 32 is arranged around the outer periphery of the first air guiding member 31 to construct a cold air guiding channel 3a and a fresh air guiding channel 3b on the first air guiding member 31 and the second air guiding member 32, respectively. The fresh air guiding channel 3b is constructed through the first outer ring side 311b of the first ring portion 311 of the first air guiding member 31 and the inner ring side of the second air guiding member 32. The second ring portion 312 of the first air guiding member 31 is connected to the first ring portion 311, and the extension direction of the second ring portion 312 is inclined relative to the depth direction of the casing 1, which makes an angle between the extension direction of the second ring portion 312 and the extension direction of the first ring portion 311. Since the second ring portion 312 extends toward the second air guiding member 32, when fresh air is vented, the fresh air will blow onto the second ring portion 312, and the fresh air can be blown along the extension direction of the second ring portion 312. In this way, when fresh air exits from the fresh air guide channel 3b, the direction of the fresh air exits at an angle to the direction of the cold air exiting from the first inner ring side 311a. Near the indoor air outlet 1c, the fresh air and cold air blow out in different directions, preventing mixing and condensation at the outer edges of either the fresh air guide channel 3b or the cold air guide channel 3a. Then, as the fresh air and cold air move away from the indoor air outlet 1c, the annular design of the first air guide 31 and the second air guide 32 creates a circulating flow. The fresh air outside the cold air can envelop it, thus allowing mixing to occur at a distance from the indoor air outlet 1c after they exit at an angle.

[0118] It is understandable that the first ring portion 311 and the second ring portion 312 of the first air guide 31 can be integrally formed ring plates, for example, formed by 3D printing, injection molding and other processes. The extension angles between the first ring portion 311 and the second ring portion 312 are different, making the overall shape of the first air guide 31 resemble a trumpet.

[0119] In some embodiments, the shape of the indoor air outlet 1c is configured as circular, and both the first air guide 31 and the second air guide 32 are configured as annular.

[0120] When the indoor air outlet 1c is constructed to be circular, the first air guide 31 and the second air guide 32 can be constructed to be annular in order to be installed in the indoor air outlet 1c. The annular construction of the first air guide 31 and the second air guide 32 allows for the formation of vortices between the fresh air and the cold air at their respective outlets, effectively utilizing aerodynamic design and facilitating effective mixing of fresh air and cold air after they exit through the fresh air guide channel 3b and the cold air guide channel 3a.

[0121] In some embodiments, the extension direction of the second ring portion 312 forms an angle α with the depth direction of the housing 1, where α can be 40°-70°.

[0122] For example, α can be 40°-50°, 50°-60°, 60°-70°, etc. For instance, α can be 40°, 45°, 50°, 55°, 60°, 65°, or 70°, etc.

[0123] It is understandable that the extension direction of the second ring portion 312 forms an angle with the depth direction of the housing 1, that is, the angle formed by the extension direction of the second ring portion 312 and the extension direction of the first ring portion 311.

[0124] When setting the extension direction of the second ring 312, this application needs to consider that the angle α between the second ring 312 and the depth direction of the casing 1 should not be too small. If α < 40°, the angle between the outlet direction of the fresh air and the outlet direction of the cold air is small. This results in the fresh air and the cold air being relatively close after they are discharged from the fresh air guide channel 3b and the cold air guide channel 3a, respectively. This makes it easy for the fresh air and the cold air to mix at the positions near the fresh air guide channel 3b and the cold air guide channel 3a. This may also cause condensation to occur at the outer edge of the fresh air guide channel 3b and the outer edge of the cold air guide channel 3a.

[0125] On the other hand, it is also necessary to consider that the angle α between the second ring 312 and the depth direction of the housing 1 should not be too large. If α > 70°, the extension direction of the second ring 312 is close to the width direction of the housing 1. This may cause the second ring 312 to block the fresh air guide channel 3b, which may not only cause the outlet of the fresh air guide channel 3b to become smaller, but may also cause the fresh air to come into contact with the second ring 312, resulting in fresh air return and affecting the effective air outlet of the fresh air.

[0126] Therefore, this application controls the range of α to 40°-70°, which can prevent fresh air and cold air from mixing at the outer edge of the fresh air guide channel 3b and the outer edge of the cold air guide channel 3a, and also avoid the second ring 312 from blocking the fresh air guide channel 3b, thereby affecting the effective air outlet of fresh air.

[0127] Please see Figure 8 and Figure 9 In some embodiments, the second ring portion 312 includes a second inner ring side 312a and a second outer ring side 312b. The second inner ring side 312a is connected to the first inner ring side 311a, and the connection between the second inner ring side 312a and the first inner ring side 311a forms the cold air outlet 3c of the cold air guide channel 3a. The second outer ring side 312b is connected to the first outer ring side 311b.

[0128] In some embodiments, the second air guide 32 includes a third ring portion 321 and a fourth ring portion 322. The third ring portion 321 is disposed at the indoor air outlet 1c and extends toward the inner cavity 1a along the depth direction of the housing 1. The third ring portion 321 is arranged around the outer periphery of the first outer ring side 311b to form a fresh air guide channel 3b together with the first outer ring side 311b. The fourth ring portion 322 is connected to the side of the third ring portion 321 away from the inner cavity 1a. The fourth ring portion 322 is arranged around the outer periphery of the second outer ring side 312b and extends in an extension direction parallel to the second ring portion 312. The fourth ring portion 322 is configured to extend the fresh air guide channel 3b. The end of the fourth ring portion 322 away from the third ring portion 321 and the end of the second outer ring side 312b away from the first outer ring side 311b together form a fresh air outlet 3d of the fresh air guide channel 3b.

[0129] In other words, when the second air guide 32 is provided with a fourth ring 322, the fourth ring 322 and the second ring 312 can jointly construct a part of the fresh air guide channel 3b, extending the outer ring side of the original first ring 311 and the fresh air guide channel 3b of the third ring 321, so that the last outlet position of the fresh air is staggered from that of the cold air, thereby further avoiding the fresh air and the cold air being staggered when they are first outlet, and avoiding the direct mixing of the two air after they are outlet.

[0130] It is understandable that the third ring 321 and the fourth ring 322 of the second air guide 32 can be integrally formed ring plates, for example, formed by 3D printing, injection molding and other processes. The different extension angles between the third ring 321 and the fourth ring 322 make the overall shape of the second air guide 32 resemble a trumpet.

[0131] Please see Figure 9 In some embodiments, the extending direction of the fourth ring portion 322 forms an angle β with the extending direction of the third ring portion 321, and the angle β can be 40°-70°.

[0132] For example, β can be 40°-50°, 50°-60°, 60°-70°, etc. For instance, β can be 40°, 45°, 50°, 55°, 60°, 65°, or 70°, etc.

[0133] Because the fourth ring 322 is arranged parallel to the extension direction of the second ring 312, and the extension directions of the third ring 321 and the fourth ring 322 form an angle β, the fresh air guide channel 3b has a bend. On the one hand, if β < 40°, that is, the extension direction of the fourth ring 322 is close to the depth direction of the casing 1, the fresh air may be close to the cold air when it is discharged, causing the fresh air and cold air to mix at the fresh air outlet 3d or the cold air outlet 3c and condensation to occur. On the other hand, if β > 70°, that is, the extension direction of the fourth ring 322 is close to the width direction of the casing 1, most of the fresh air may be blown out along the width direction of the casing 1 after being discharged, making it difficult for the fresh air to mix with the cold air after it is blown out and away from the indoor air outlet 1c, thus affecting the mixing effect of fresh air and cold air in the indoor unit 100.

[0134] Therefore, controlling the range of β to around 40°-70° can not only prevent the fresh air and cold air from mixing near the fresh air outlet 3d and the cold air outlet 3c, but also prevent the fresh air and cold air from failing to effectively mix after being blown out of the indoor air outlet 1c.

[0135] In some embodiments, the first ring portion 311 forms a first cavity 311c, which is isolated from the fresh air guide channel 3b and the cold air guide channel 3a. The first cavity 311c is configured to reduce heat transfer between the first ring portion 311 and the third ring portion 321.

[0136] This application not only considers the situation where fresh air and cold air mix and condense at the fresh air outlet 3d and the cold air outlet, but also considers the situation where the low temperature of the cold air guide channel 3a cools the fresh air guide channel 3b, causing water vapor in the fresh air to condense in the fresh air guide channel 3b. To address this, this application forms a first cavity 311c in the first ring portion 311 to isolate the fresh air guide channel 3b from the other air. Utilizing the poor thermal conductivity of air, this reduces heat transfer between the first ring portion 311 and the third ring portion 321, thereby reducing the impact of the low temperature in the cold air guide channel 3a on the fresh air guide channel 3b and helping to prevent condensation in the fresh air guide channel 3b.

[0137] Please see Figure 9 In some embodiments, the first ring portion 311 includes a main ring portion 3111 and an extended ring portion 3112. The main ring portion 3111 has a first inner ring side 311a. The extended ring portion 3112 is integrally formed on the main ring portion 3111 and has a first outer ring side 311b. The extended ring portion 3112 is spaced apart from the first outer ring side 311b along the width direction of the housing 1, so that a first cavity 311c is formed between the extended ring portion 3112 and the main ring portion 3111.

[0138] In this application, when the first cavity 311c is set, the first ring portion 311 is located on the side close to the inner cavity 1a. When the first ring portion 311 emits cold air, the temperature of the first inner ring side 311a is relatively low. By setting the first ring portion 311 as a main ring portion 3111 and an outer ring portion 3112, and using the outer ring portion 3112 to be spaced from the main ring portion 3111 to form the first cavity 311c inside the first ring portion 311, the transfer of the lower temperature from the lower temperature of the first inner ring side 311a to the first outer ring side 311b is reduced, thereby avoiding cooling and condensation of water vapor in the fresh air in the fresh air guide channel 3b.

[0139] Furthermore, the main ring 3111 and the outer ring 3112 can be integrally formed. For example, the main ring 3111 and the outer ring 3112 can be integrally formed by 3D printing, injection molding and other processing methods to avoid air leakage between the fresh air guide channel 3b and the cold air guide channel 3a due to gaps in the main body of the first ring 311.

[0140] In some embodiments, a second cavity 311d is provided on the outer periphery of the second ring portion 312. The second cavity 311d is isolated from the fresh air outlet 3d and the cold air outlet 3c. The second cavity 311d is configured to reduce heat transfer between the second ring portion 312 and the fourth ring portion 322.

[0141] In this application, because the second ring portion 312 is located near the fresh air outlet 3d and the cold air outlet 3c, condensation is easily generated due to the mixing of fresh air and cold air at the second ring portion 312. This application provides a second cavity 311d on the outer periphery of the second ring portion 312, utilizing the poor thermal conductivity of air to reduce heat transfer between the second ring portion 312 and the fourth ring portion 322, thus preventing water vapor in the fresh air from condensing in the fourth ring portion 322 or on the second outer ring side 312b of the second ring portion 312 before it is expelled.

[0142] Please see Figure 9 and Figure 10 In some embodiments, the air guiding structure 3 further includes a heat insulation element 33, which is arranged around the outer periphery of the second outer ring side 312b, and the heat insulation element 33 and the second outer ring side 312b are spaced apart to form a second cavity 311d.

[0143] Since the fourth ring portion 322 and the second ring portion 312 extend the fresh air guide channel 3b, in order to improve the heat insulation effect of the extended fresh air guide channel 3b, a heat insulation element 33 is also provided around the outer periphery of the second ring portion 312. By spaced between the heat insulation element 33 and the second outer ring side 312b, heat transfer between the second ring portion 312 and the fourth ring portion 322 is reduced. Moreover, the setting of the heat insulation element 33 can further reduce heat transfer. For example, by using heat insulation materials such as glass fiber or asbestos, the heat transfer between the fresh air guide channel 3b and the cold air guide channel 3a can be reduced.

[0144] In addition, the second ring 312 is located closer to the external environment, making it prone to condensation and contamination with dust, mold, and other dirt. Therefore, a separate heat insulation component 33 is provided on the second ring 312 to form a second cavity 311d, which allows the heat insulation component 33 to be easily removed for cleaning, improving the convenience of cleaning the indoor unit 100 for the user.

[0145] It is understandable that when the heat insulation element 33 is arranged around the outer periphery of the second ring portion 312, the shape of the heat insulation element 33 is similar to the shape of the second ring portion 312. For example, when the second ring portion 312 is square or circular, the heat insulation element 33 can also be square or circular.

[0146] Please see Figure 10In some embodiments, the second outer ring side 312b is provided with an abutment portion 3121 and a support portion 3122. The abutment portion 3121 protrudes from the second outer ring side 312b along the width direction of the housing 1, and the abutment portion 3121 is located at the end of the second outer ring side 312b away from the first ring portion 311. The abutment portion 3121 abuts against the heat insulation member 33, so that the heat insulation member 33 is spaced apart from the second outer ring side 312b. The support portion 3122 is spaced apart from the abutment portion 3121 along the depth direction of the housing 1. The support portion 3122 is located at the end of the second outer ring side 312b near the first ring portion 311. The support portion 3122 is configured to support the heat insulation member 33, so that the heat insulation member 33 is detachably connected to the second outer ring side 312b.

[0147] For example, when the heat insulation member 33 is installed on the second outer ring side 312b, one surface of the heat insulation member 33 abuts against the abutting portion 3121, thus spacing the heat insulation member 33 from the second outer ring side 312b. Simultaneously, the supporting portion 3122, by supporting the other surface of the heat insulation member 33, locks the position of the heat insulation member 33, preventing it from falling off the second outer ring side 312b. This application first uses the abutting portion 3121 to position the heat insulation member 33 on the second outer ring side 312b, forming a second cavity 311d between the heat insulation member 33 and the second outer ring side 312b. Then, the supporting portion 3122 supports the heat insulation member 33, preventing it from falling off the second outer ring side 312b. In this way, the heat insulation member 33 can be positioned and installed on the second outer ring side 312b while also achieving stable installation and preventing it from falling off.

[0148] Optionally, the abutting part 3121 and the supporting part 3122 may be protrusions or bumps protruding from the second outer ring side 312b, which are not specifically limited here.

[0149] It is understandable that, since the heat insulation component 33 is arranged in a ring on the second outer ring side 312b, there are multiple abutting parts 3121 and multiple supporting parts 3122 on the second outer ring side 312b. Multiple abutting parts 3121 and multiple supporting parts 3122 are arranged in a ring on the second outer ring side 312b to correspondingly install the heat insulation component 33.

Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the air conditioner and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
