Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to an indoor air outlet duct and a duct-type air conditioner. Background Technology

[0002] Traditional household wall-mounted air conditioners are divided into indoor and outdoor units. However, regardless of the type of model, because the indoor unit contains core components such as heat exchangers, motors, and fans, its external dimensions cannot be designed to be exquisite and compact, thus making it difficult to integrate well with the home decoration environment. Utility Model Content

[0003] This application provides an indoor air outlet duct and a duct-type air conditioner. The duct-type air conditioner delivers air into the room through the indoor air outlet duct, making it suitable for home environments and providing good integration. Furthermore, the indoor air outlet duct has good air delivery performance, which can improve the comfort of the duct-type air conditioner.

[0004] One aspect of this application provides an indoor air outlet duct, comprising: a duct shell, the duct shell including a side plate and a front panel, the side plate and the front panel together forming an air outlet duct; wherein, the front panel includes a decorative part and a first air outlet part, the first air outlet part being located on both sides of the decorative part, the first air outlet part having first air outlet holes distributed thereon; a first air softening plate, the first air softening plate being disposed inside the duct shell, the first air softening plate being perpendicular to the extension direction of the air outlet duct and being spaced apart along the extension direction of the air outlet duct, and the first air softening plate having first air softening holes distributed thereon.

[0005] The indoor air outlet duct provided in this application has a casing that forms an air outlet channel, and the panel of the casing is provided with a decorative part and a first air outlet. While delivering air to the room through the air outlet channel via the first air outlet, the decorative part enhances the appearance of the indoor air outlet duct. Furthermore, by placing the first air outlet on both sides of the decorative part, it is not only more aesthetically pleasing but also provides a more uniform airflow. In addition, by installing a first air deflector plate inside the casing, perpendicular to the extension direction of the air outlet channel and spaced at intervals along the extension direction, the first air deflector plate disperses and slows down the airflow within the air outlet channel before delivery, resulting in better airflow performance, more uniform and gentler airflow, and improved comfort of the ducted air conditioner.

[0006] In one possible implementation, the panel further includes a second air outlet having second air vents; wherein the second air outlet is connected between the decorative section and the first air outlet, and the second air outlet is located on the side of the decorative section facing the side panel.

[0007] In this way, the first and second air outlets together can increase the air outlet area of ​​the panel, expand the air outlet area of ​​the indoor air outlet duct, and improve the air supply efficiency and air supply effect of the indoor air outlet duct.

[0008] Furthermore, by positioning the second air outlet on the side of the decorative section facing the side panel, the first air outlet connected to it is inclined towards the inside of the duct casing. This increases the airflow to the first air outlet, resulting in better airflow uniformity throughout the entire duct. Simultaneously, the first air outlet's airflow direction is away from the wall, preventing interference from the wall. Additionally, the airflow from the second air outlet can converge with that from the first air outlet, slowing down the overall airflow velocity and enhancing the draft-free effect of the indoor air duct.

[0009] In one possible implementation, the indoor air outlet duct further includes a second air softening plate, which is disposed inside the duct housing. The extension direction of the second air softening plate is the same as the extension direction of the decorative part, and second air softening holes are distributed on the second air softening plate.

[0010] In this way, most of the airflow along the air outlet duct passes through the first air deflector, then flows to the second air deflector, and finally is delivered outwards through the air outlet on the panel. The indoor air outlet duct can provide three levels of air deflection, which can enhance the air deflection effect of the indoor air outlet duct and achieve an ultra-soft and ultra-comfortable air delivery effect.

[0011] In one possible implementation, the second airflow deflector is connected between the two second air outlets on both sides, and the air inlet surface of the second airflow deflector does not extend beyond the end of the first air outlet that is connected to the second air outlet.

[0012] In this way, the airflow in the central area of ​​the air outlet duct is large and the velocity is fast. Most of this airflow passes through the first softening plate, the second softening plate, and the second air outlet in sequence, undergoing a three-stage softening effect. This effectively reduces the velocity of the airflow exiting the central area of ​​the air outlet duct, truly achieving a softening effect. Meanwhile, the airflow in the edge area of ​​the air outlet duct has a relatively small flow rate and a relatively low velocity. This airflow only passes through the first softening plate and the first air outlet for a two-stage softening effect, ensuring that the first air outlet has a similar air volume and velocity as the second air outlet.

[0013] In one possible implementation, the diameter of the second soft air hole is larger than the diameter of the second air outlet hole.

[0014] In one possible implementation, the diameter of the first air outlet is the same as the diameter of the second air outlet.

[0015] In this way, when the opening area ratio of the first air outlet is equal to that of the second air outlet, the pressure and velocity of the airflow from the first air outlet and the airflow from the second air outlet are also equal, resulting in uniform airflow throughout the air outlet, good balance, and high reliability.

[0016] In one possible implementation, the second soft air holes are evenly distributed on the second soft air plate; and / or, the second soft air holes located on both sides of the central axis of the second soft air plate extend obliquely toward the corresponding second air outlet.

[0017] By evenly distributing the second soft air holes on the second soft air plate, the uniformity of the soft air flow of the second soft air plate can be improved, the air pressure on the second soft air plate is more balanced, and the reliability of the second soft air plate is higher.

[0018] By tilting the second airflow holes on both sides of the central axis of the second airflow deflector toward the second air outlets on both sides, the second airflow deflector can guide the airflow to the second air outlets on both sides, allowing the airflow to flow out quickly from the second air outlets on both sides. This enhances the orderliness of the airflow within the air outlet duct and improves the air delivery efficiency of the indoor air outlet duct.

[0019] In one possible implementation, there is a gap between the first and second wind deflectors.

[0020] In this way, the gap between the two allows the airflow flowing from the first air deflector to diffuse to the second air deflector, and the angle between the airflow and the second air deflector allows the airflow to pass smoothly through the second air deflector orifice. This ensures smooth airflow through the indoor air outlet duct. It also prevents the airflow flowing over the first air deflector from rubbing against the surface of the second air deflector, thus avoiding noise within the duct.

[0021] In one possible implementation, the indoor air duct further includes a partition plate, which is connected between the second air outlet and the corresponding side plate, and the partition plate has a ventilation opening.

[0022] In this way, the partition plate connects the second air outlet and the side panel, providing complete support between the decorative section and the side panel. The partition plate, the second air outlet, and the second air deflector form a frame support structure between the decorative section and the side panel, which can improve the reliability and service life of the indoor air outlet duct. Furthermore, the baffle between adjacent air vents has a diversion function, reducing the viscosity effect between gases and improving the airflow uniformity of the first air outlet.

[0023] In one possible implementation, the extension direction of the partition plate is the same as the extension direction of the second air outlet.

[0024] In this way, the partition plate and the second air outlet have good integrity and consistency, which can improve the support and reliability of both.

[0025] In one possible implementation, the second air outlet is perpendicular to the decorative part.

[0026] In this way, when the decorative part is subjected to external force, the force can be propagated along the plane of the second air outlet, the second air outlet provides better support for the decorative part, and the overall strength and reliability of the indoor air outlet duct are higher.

[0027] In one possible implementation, the first soft air holes are uniformly distributed on the first soft air plate; and / or, the first soft air holes are arranged in an array on the first soft air plate.

[0028] By evenly distributing the first soft air holes on the first soft air plate, the uniformity of the soft air flow can be improved, and stress concentration in the indoor air outlet duct can be avoided, thus enhancing the reliability of the indoor air outlet duct. Furthermore, by arranging the first soft air holes in an array on the first soft air plate, the distribution of the first soft air holes becomes more regular, increasing their density and resulting in more dispersed airflow within the air outlet duct.

[0029] In one possible implementation, the decorative part is provided with a light strip, the light strip being arranged in the direction of the extension of the tube shell.

[0030] In this way, the light strips can serve as indoor lighting, providing an additional function for the indoor air ducts and making their functions more diverse. Furthermore, the light strips also have a decorative function, illuminating the indoor air ducts themselves and enhancing their aesthetics.

[0031] In one possible implementation, the light strip is located on the front of the decorative part, and / or the light strip is located on the side walls of the decorative part.

[0032] In one possible implementation, the extension line of the outer surface of the decorative part and the side plate together form a right-angled isosceles triangle.

[0033] In this way, the side plates on both sides of the duct shell are the same width, and the angles between the panel and the two walls at the corners are also the same. The air supply area of ​​the panel expands evenly towards both walls, resulting in a larger overall air supply area for the indoor air outlet duct and better temperature regulation of the indoor space. Furthermore, the walls do not interfere with the airflow, ensuring smooth air delivery from the indoor air outlet duct and preventing any loss of air supply efficiency.

[0034] In one possible implementation, the indoor air duct extends vertically.

[0035] In this way, the indoor air outlet duct covers the entire height of the room, resulting in a large air volume and a wide air delivery area, which improves the air delivery efficiency and uniformity of the ducted air conditioner. Furthermore, the vertically extending indoor air outlet duct covers more of the user's activity area, enhancing the user experience and reducing the power and energy consumption of the ducted air conditioner. Additionally, the vertically extending indoor air outlet duct is easier to install and provides better support, improving the reliability of the installation.

[0036] Another aspect of this application provides a ducted air conditioner, comprising: a main unit installed outdoors; an outdoor air supply duct with its inlet connected to the main unit; and an indoor air outlet duct as described above, the indoor air outlet duct being connected to the outlet of the air supply duct.

[0037] The ducted air conditioner provided in this application has its main unit installed outdoors, and it supplies air indoors through an indoor air outlet duct. The indoor air outlet duct is small in size and can be laid along the indoor wall, blending into the indoor space. Furthermore, since only the indoor air outlet duct is installed indoors, and there are no compressors, fans, motors, or other components, the indoor noise generated when the ducted air conditioner supplies air is relatively low, which can improve the performance of the ducted air conditioner.

[0038] In addition, since ducted air conditioners include the aforementioned indoor air supply ducts, they possess all the technical effects of indoor air supply ducts, which will not be elaborated here.

[0039] In one possible implementation, the ducted air conditioner further includes: an outdoor return air duct, the return air inlet of which is connected to the indoor unit, and the air outlet of which is connected to the main unit.

[0040] In this way, ducted air conditioners can deliver outside air into the room through outdoor supply ducts and indoor exhaust ducts, and extract indoor air back to the outside environment through outdoor return ducts, thus achieving a fresh air function. This accelerates indoor air circulation, quickly regulates indoor temperature, and ensures indoor air quality.

[0041] In one possible implementation, the ducted air conditioner further includes:

[0042] The down-conversion duct includes a down main duct, a down branch duct, and a down second branch duct. The first end of the down main duct is connected to the lower end of the indoor air outlet duct. The first ends of the down branch duct and the down second branch duct are both connected to the second end of the down main duct. The second end of the down branch duct is connected to the outdoor air supply duct, and the second end of the down second branch duct is connected to the outdoor return air duct.

[0043] The upward conversion air duct includes an upper main duct, an upper branch duct, and an upper second branch duct. The first end of the upper main duct is connected to the upper end of the indoor air outlet duct. The first ends of the upper branch duct and the upper second branch duct are both connected to the second end of the upper main duct. The second end of the upper branch duct is connected to the outdoor return air duct, and the second end of the upper second branch duct is connected to the outdoor supply air duct.

[0044] In this way, when the ducted air conditioner is in cooling mode, the lower end of the indoor air outlet duct serves as the air inlet, and the upper end serves as the air outlet. The supplied cold air flows upward along the path of the outdoor air outlet duct, the next branch duct, the lower main duct, and the indoor air outlet duct. The return air flows along the path of the upper main duct, the upper second branch duct, and the outdoor return air duct. At this time, the indoor air outlet duct operates in a bottom-in, top-out mode, and the overall flow direction of the cold air supplied by the indoor air outlet duct is an upward and outward parabolic trajectory, which can achieve a canopy-like cooling air supply and avoid direct cold air blowing on users.

[0045] When the ducted air conditioner is in heating mode, the upper end of the indoor air outlet duct serves as the air inlet, and the lower end serves as the air outlet. The supplied warm air flows downwards along the path of the outdoor air outlet duct, the upper branch duct, the upper main duct, and the indoor air outlet duct. The return air flows along the path of the lower main duct, the lower second branch duct, and the outdoor return air duct. At this time, the indoor air outlet duct operates in an upper intake and lower return mode, and the overall flow direction of the warm air delivered by the indoor air outlet duct is a downward and outward parabolic trajectory, which can achieve carpet-like heating and air delivery, allowing warm air to be quickly and directly blown to the user.

[0046] In one possible implementation, the main unit includes a housing and an evaporator, condenser, compressor, and fan disposed within the housing. Attached Figure Description

[0072] As described in the background section, traditional household wall-mounted ducted air conditioners consist of an indoor unit and an outdoor unit. The indoor unit needs to integrate components such as a compressor, heat exchanger, motor, and fan. Therefore, the indoor unit of a wall-mounted ducted air conditioner occupies a large space and cannot be well integrated into the indoor environment.

[0073] In view of this, this application provides an indoor air outlet duct and a ducted air conditioner. The main unit of the ducted air conditioner is installed outdoors, and air is supplied indoors through the indoor air outlet duct. The indoor air outlet duct is small in size and can be laid along the indoor wall, blending into the indoor space. Furthermore, since only the indoor air outlet duct is installed indoors, without compressors, fans, motors, or other components, the indoor noise generated when the ducted air conditioner supplies air is relatively low, which can improve the performance of the ducted air conditioner.

[0074] The indoor air outlet duct's casing forms an air outlet channel, and the casing's panel includes a decorative section and a first air outlet. While the first air outlet delivers air into the room through the air outlet channel, the decorative section enhances the duct's appearance. Furthermore, placing the first air outlet on either side of the decorative section not only improves aesthetics but also ensures more even airflow. Additionally, by incorporating a first air deflector plate within the casing, perpendicular to and spaced along the air outlet channel's extension direction, the plate disperses and slows the airflow before delivery, resulting in better, more even, and gentler airflow from the indoor air outlet duct, thus improving the comfort of the ducted air conditioning system.

[0075] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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, 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.

[0076] Figure 1 This is a structural schematic diagram of a ducted air conditioner provided in an embodiment of this application. Figure 2 for Figure 1 A structural schematic diagram of a ducted air conditioner from another perspective.

[0077] Reference Figure 1 and Figure 2 As shown in the figure, this application provides a ducted air conditioner, which includes a main unit 10, an outdoor air supply duct 20, and an indoor air outlet duct 30. The main unit 10 is installed outdoors. One end of the outdoor air supply duct 20 is connected to the main unit 10, and the other end extends into the room. The indoor air outlet duct 30 is installed indoors and communicates with the outdoor air supply duct 20.

[0078] The main unit 10 draws in outside air, which is then heated within the main unit 10 before being sent into the outdoor air supply duct 20. The air flows along the outdoor air supply duct 20 into the indoor air outlet duct 30, and then flows along the indoor air outlet duct 30 and is blown into the room. Thus, the ducted air conditioner delivers air into the room.

[0079] Compared to wall-mounted air conditioners and traditional ducted air conditioners, all types of air conditioners include an indoor unit, which integrates components such as a fan 15, a compressor 14, and a heat exchanger. The ducted air conditioner provided in this embodiment integrates all functions such as air extraction and heat exchange into an external main unit 10, with only an indoor air outlet duct 30 installed indoors, connected to the main unit 10 via an outdoor air supply duct 20.

[0080] With this configuration, the indoor portion of the ducted air conditioner in this embodiment only includes the indoor air outlet duct 30. The indoor air outlet duct 30 has a simple structure and can be long and slender. It can be installed along the interior wall, for example, extending along a corner. The indoor air outlet duct 30 occupies little space and blends better into the interior space. Furthermore, components that generate significant operating noise are integrated into the outdoor unit 10, leaving only airflow within the indoor air outlet duct 30. Therefore, the ducted air conditioner produces very little noise indoors, even achieving a silent operation, thus enhancing the user experience.

[0081] Continue to refer to Figure 1 and Figure 2 The ducted air conditioner provided in this application embodiment may further include an outdoor return air duct 40, with the return air inlet 114 of the outdoor return air duct 40 connected to the indoor unit, and the air outlet of the outdoor return air duct 40 connected to the main unit 10. Indoor air can enter the outdoor return air duct 40 through the return air inlet 114, then flow along the outdoor return air duct 40 to the main unit 10, and finally be discharged to the outside environment through the exhaust outlet on the main unit 10.

[0082] With this configuration, the ducted air conditioner can deliver outside air into the room through the outdoor supply air duct 20 and the indoor air outlet duct 30, and simultaneously extract indoor air to the outside environment through the outdoor return air duct 40. When the ducted air conditioner is working, it delivers air into the room through the indoor air outlet duct 30, and at the same time, extracts indoor air to the outside through the outdoor return air duct 40.

[0083] In other words, the ducted air conditioner of this application embodiment can supply air into the room and exhaust indoor air to the outside, thus achieving a fresh air function. This accelerates airflow within the indoor environment, enhances indoor air circulation, and achieves rapid regulation of indoor temperature. Furthermore, by continuously supplying fresh air into the room while simultaneously exhausting existing indoor air, it exchanges indoor air, ensuring indoor air quality, preventing air pollution, and avoiding air conditioning sickness caused by polluted air.

[0084] Especially in summer for cooling or winter for heating, indoor doors and windows are usually kept tightly closed to maintain indoor temperature. The ducted air conditioner in this embodiment provides ventilation, quickly adjusting indoor temperature while offering a comfortable environment for users. It can promptly remove indoor odors, eliminate dust and bacteria floating in the indoor air, and dehumidify to prevent condensation, mold, and rot caused by moisture, creating a fresh and comfortable indoor environment for users.

[0085] Additionally, refer to Figure 1 or Figure 2 In this embodiment, the indoor air outlet duct 30 can extend vertically. Alternatively, the indoor air outlet duct 30 can extend along the height of the room. In this way, the air supply area of ​​the indoor air outlet duct 30 covers most or even all of the area along the height of the room. The indoor air outlet duct 30 has a large air supply volume and a wide air supply area, which can improve the air supply efficiency and uniformity of the duct air conditioner.

[0086] Furthermore, the vertically extending indoor air outlet duct 30 extends from the ceiling towards the floor. This allows the air delivery area of ​​the indoor air outlet duct 30 to cover a wider portion of the user's activity area. As a result, users can more quickly experience the temperature regulation effect of the ducted air conditioner, especially when they need a quick cool breeze or desire a warmer temperature; the vertically extending indoor air outlet duct 30 provides a better user experience. Simultaneously, because the temperature felt by the user is closer to the air delivery temperature of the indoor air outlet duct 30, it helps reduce the power consumption of the ducted air conditioner, thus saving energy.

[0087] Furthermore, the vertically extending indoor air outlet duct 30 is easier to install and secure. The bottom and top of the indoor air outlet duct 30 can be supported and secured; for example, the top of the indoor air outlet duct 30 can abut against the ceiling or a support, and the bottom of the indoor air outlet duct 30 can abut against the ground or a support. In addition, the lateral support provided by the wall corners extending vertically within the room ensures that the indoor air outlet duct 30 is stably and securely installed indoors.

[0088] Figure 3 This is a schematic diagram of the main unit in a ducted air conditioner provided in an embodiment of this application. (Refer to...) Figure 3 As shown, the main unit 10 includes a housing 11, which is the main support structure of the main unit 10. The aforementioned components used to realize the ventilation and heat exchange functions can all be integrated into the housing 11.

[0089] For example, the housing 11 can be rectangular and can be erected on a pre-installed outdoor mounting bracket. For instance, the length of the housing 11 (X direction shown in the figure) is arranged horizontally along the outdoor wall surface, the width of the housing 11 (Y direction shown in the figure) corresponds to the thickness of the wall, and the height of the housing 11 (Z direction shown in the figure) extends along the height of the outdoor wall surface. In this way, the main unit 10 occupies less outdoor space and has less impact on the building's appearance.

[0090] Figure 4 for Figure 3 The exploded structure diagram of the host computer. (Refer to...) Figure 4 As shown, the housing 11 may include a main housing 111 and a front cover 112, with the front cover 112 positioned on the opening of the main housing 111. The front cover 112 and the main housing 111 together form a receiving cavity. An air supply port 113 communicating with the outdoor air supply duct 20 and a return air port 114 communicating with the outdoor return air duct 40 may be located on the main housing 111; for example, both the air supply port 113 and the return air port 114 may be located on the top wall of the main housing 111. The front cover 112 may include a support plate 1121 and a cover plate 1122, with the cover plate 1122 affixed to the side of the support plate 1121 facing away from the main housing 111. The support plate 1121 primarily provides support, while the cover plate 1122 can be customized for aesthetic purposes.

[0091] Continue to refer to Figure 4 The housing 11 houses an evaporator 12, a condenser 13, a compressor 14, and a fan 15. The evaporator 12 and the condenser 13 are connected by a refrigerant circuit, and the compressor 14 is located on the refrigerant circuit, enabling the refrigerant to circulate between the evaporator 12 and the condenser 13.

[0092] Taking the air conditioning cooling process as an example, the gas inside the casing 11 is cooled down after passing through the evaporator 12. The fan 15 draws the cold air into the outdoor air supply duct 20, and then flows into the indoor air supply duct 30 through the outdoor air supply duct 20, finally delivering cold air into the room through the indoor air supply duct to lower the indoor temperature. Under the action of the fan 15, the indoor air then flows back into the casing 11 through the outdoor return air duct 40. This cycle continues.

[0093] Taking the heating process of an air conditioner as an example, the gas inside the casing 11 is heated by the condenser 13. The hot air is drawn into the outdoor air supply duct 20, then flows into the indoor air supply duct 30, and finally, the warm air is delivered into the room through the indoor air supply duct to raise the indoor temperature. Under the action of the fan 15, the indoor air then flows back into the casing 11 through the outdoor return air duct 40. This cycle continues.

[0094] During this process, the low-temperature, liquid refrigerant is compressed by compressor 14 into a high-pressure, liquid refrigerant, which then enters evaporator 12. In evaporator 12, it absorbs heat and transforms into a low-pressure, gaseous refrigerant. The low-pressure, gaseous refrigerant is then compressed again by compressor 14 into a high-pressure, gaseous refrigerant, which enters condenser 13. In condenser 13, it releases heat and transforms into a low-pressure, liquid refrigerant. This cycle continues.

[0095] For example, the fan 15 can be a high static pressure centrifugal fan to reduce the operating noise of the fan 15, reduce the airflow noise in the outdoor supply air duct 20 and the outdoor return air duct 40, and contribute to the noise reduction and quietness of the duct air conditioner.

[0096] Continue to refer to Figure 4 Since the refrigerant releases heat in the condenser 13, this heat is dissipated from the condenser 13 into the casing 11. To address this, a radiator 16 can be installed inside the casing 11, positioned close to the condenser 13, to dissipate heat from the condenser 13 and maintain the interior of the casing 11 at a suitable temperature.

[0097] The radiator 16 can be a cooling fan. An air inlet 115 and an air outlet 116 can be provided on the casing 11. Under the action of the cooling fan, outside air enters through the air inlet 115 on the casing 11, flows through the condenser 13, carries away the heat from the condenser 13, and is then discharged through the air outlet 116 on the casing 11. For example, the axis of the cooling fan can correspond to the thickness direction of the casing 11. The air inlet 115 can be located on the side wall of the main casing 111, and the air outlet 116 can be located on the support plate 1121 of the front cover 112. A grille 11221 can be provided on the cover plate 1122 of the front cover 112 at the air outlet 116 location.

[0098] Figure 5 for Figure 4A schematic diagram of the main unit after removing the front cover. (Refer to...) Figure 5 As shown, a first partition 117 can be provided inside the casing 11, dividing the casing 11 along the height direction into a first receiving cavity 1111 and a second receiving cavity 1112, with the second receiving cavity 1112 located above the first receiving cavity 1111. The compressor 14, condenser 13, and radiator 16 can be disposed in the first receiving cavity 1111, while the evaporator 12 and fan 15 can be disposed in the second receiving cavity 1112. Therefore, in the ducted air conditioner of this embodiment, the first receiving cavity 1111 of the main unit 10 integrates components from the outdoor unit of a conventional air conditioner, and the second receiving cavity 1112 of the main unit 10 integrates components from the indoor unit of a conventional air conditioner.

[0099] The first receiving cavity 1111 may also be provided with a second partition 118, which divides the first receiving cavity 1111 along its length into a first sub-cavity 1113 and a second sub-cavity 1114. The compressor 14 can be located in the first sub-cavity 1113, and the condenser 13 and radiator 16 can be located in the second sub-cavity 1114. In this way, the compressor 14 is completely isolated from the condenser 13 and radiator 16, and the second sub-cavity 1114 forms a separate heat dissipation space for the condenser 13, which can improve the heat dissipation efficiency and effect of the condenser 13.

[0100] Combination Figure 4 and Figure 5 For the fan 15 and evaporator 12 located in the second receiving cavity 1112, the air inlet of the fan 15 can face the side where the return air inlet 114 on the casing 11 is located, and the air outlet of the fan 15 can communicate with the air supply outlet 113 on the casing 11. The evaporator 12 can be located between the return air inlet 114 on the casing 11 and the fan 15. Thus, as Figure 5 As shown by the dashed arrow, under the negative pressure of the fan 15, indoor air enters the casing 11 through the outdoor return air duct 40 and from the return air inlet 114 on the casing 11. The air entering the casing 11 flows through the evaporator 12 and is then sent into the outdoor supply air duct 20 by the fan 15.

[0101] like Figure 5 As shown, in this embodiment, the housing 11 may also be provided with an air guide plate 119 in the second receiving cavity 1112. The air guide plate 119 and the housing 11 (e.g., the top wall of the housing 11) form an air guide channel 1191, which is connected to the return air port 114 on the housing 11. Furthermore, the air guide plate 119 may be provided with a plurality of air guide holes 1192, all of which are distributed in the area of ​​the evaporator 12 facing away from the fan 15, and the air guide holes 1192 are connected to the space of the evaporator 12 facing away from the fan 15.

[0102] With this configuration, under the guidance of the air duct 1191, all the air entering from the return air inlet 114 of the casing 11 flows into the first receiving cavity 1111 from the side of the evaporator 12 facing away from the fan 15. This ensures that the airflow passes entirely through the evaporator 12 before flowing into the fan 15. This prevents the airflow entering from the return air inlet 114 from bypassing the evaporator 12 and being directly drawn into the fan 15, ensuring complete and thorough heat exchange between the airflow and the evaporator 12, thus improving the temperature regulation rate and effect of the ducted air conditioner. Furthermore, the design of multiple air guide holes 1192 allows the airflow within the air duct 1191 to flow more evenly across the entire surface of the evaporator 12, reducing airflow turbulence and improving the cooling uniformity of the evaporator 12.

[0103] For example, along the direction away from the fan 15, the opening area of ​​the air guide holes 1192 on the air guide plate 119 can gradually increase. This gradual increase in the opening area of ​​the air guide holes 1192 can include increasing the density of the air guide holes 1192 and increasing the opening area of ​​a single air guide hole 1192. This prevents airflow from concentrating and flowing out from the area near the evaporator 12, thus avoiding ineffective utilization of the area of ​​the air guide channel 1191 away from the evaporator 12. Furthermore, it ensures sufficient airflow circulation within the first receiving cavity 1111, and a more uniform airflow distribution allows for more thorough contact between the air and the evaporator 12, improving the heat exchange effect of the evaporator 12.

[0104] Figure 6 This is a schematic diagram of the structure of a ducted air conditioner after the main unit has been removed, as provided in an embodiment of this application. (Refer to...) Figure 6 As shown, when the ducted air conditioner also includes an outdoor return air duct 40, the outdoor return air duct 40 can also be connected to the indoor air supply duct 30. In this way, the outdoor return air duct 40 can be integrated with the indoor air supply duct 30 at the indoor return air inlet 114. The indoor structure of the ducted air conditioner is more centralized and simpler, which can improve the indoor aesthetics of the ducted air conditioner and facilitate its indoor installation.

[0105] Based on this, this embodiment also optimizes the air supply path and return path of the duct air conditioner for the aforementioned indoor air outlet duct 30 extending vertically, so that the duct air conditioner can achieve the distribution of cold and warm air, thereby improving the performance of the duct air conditioner.

[0106] Specifically, such as Figure 6As shown in this embodiment, the outdoor ductwork of the ducted air conditioner may further include a downward conversion duct 50 and an upward conversion duct 60. The downward conversion duct 50 connects the outdoor supply air duct 20, the outdoor return air duct 40, and the indoor air outlet duct 30, while the upward conversion duct 60 also connects the outdoor supply air duct 20, the outdoor return air duct 40, and the indoor air outlet duct 30. By switching the gas flow path through the downward conversion duct 50 and the upward conversion duct 60, the effect of distributing cold and warm air is achieved.

[0107] The down-conversion duct 50 includes a down main duct 51, a down branch duct 52, and a down second branch duct 53. The first end of the down main duct 51 is connected to the lower end of the indoor air outlet duct 30. The first ends of the down branch duct 52 and the down second branch duct 53 are both connected to the second end of the down main duct 51. The second end of the down branch duct 52 is connected to the outdoor air supply duct 20, and the second end of the down second branch duct 53 is connected to the outdoor return air duct 40.

[0108] The upper conversion duct 60 includes an upper main duct 61, an upper branch duct 62, and an upper second branch duct 63. The first end of the upper main duct 61 is connected to the upper end of the indoor air outlet duct 30. The first ends of the upper branch duct 62 and the upper second branch duct 63 are both connected to the second end of the upper main duct 61. The second end of the upper branch duct 62 is connected to the outdoor air supply duct 20, and the second end of the upper second branch duct 63 is connected to the outdoor return air duct 40.

[0109] like Figure 6 As shown by the solid arrows, when the ducted air conditioner is in cooling mode, the lower end of the indoor air outlet duct 30 serves as the air inlet 30a, and the upper end serves as the return air end 30b. The supplied cold air enters the outdoor air outlet duct 20 from the casing 11, and then enters the next branch duct 52. It flows along the next branch duct 52 to the lower main duct 51, and then enters the indoor air outlet duct 30 from the air inlet 30a at the lower end of the indoor air outlet duct 30, flowing upwards within the duct. The return air enters from the return air end 30b at the upper end of the indoor air outlet duct 30, flows along the upper main duct 61 to the upper second branch duct 63, and then flows from the upper second branch duct 63 to the outdoor return air duct 40, finally entering the casing 11.

[0110] In this way, the cold air generated during cooling flows from bottom to top within the indoor air outlet duct 30. Within the indoor air outlet duct 30, the cold airflow velocity is higher in the central area and relatively lower at the edges, resulting in an overall upward and outward parabolic trajectory. Thus, during cooling, the indoor air outlet duct 30 operates in a bottom-in, top-out mode, achieving a canopy-like cooling airflow. Canopy-like cooling airflow means that the cold airflow flows from bottom to top and gradually disperses, with the cold airflow from the indoor air outlet duct 30 primarily concentrated and dispersed in the upper part of the room, preventing direct cold air from blowing onto users.

[0111] like Figure 6As shown by the dotted arrow, when the ducted air conditioner is in heating mode, the upper end of the indoor air outlet duct 30 serves as the air inlet 30a, and the lower end serves as the return air end 30b. The warm airflow enters the outdoor air outlet duct 20 from the casing 11, and then enters the upper branch duct 62. It flows along the upper branch duct 62 to the upper main duct 61, and then enters the indoor air outlet duct 30 from the air inlet 30a at the upper end of the indoor air outlet duct 30, flowing downwards within the duct. The return airflow enters from the return air end 30b at the lower end of the indoor air outlet duct 30, flows along the lower main duct 51 to the lower second branch duct 53, and then flows from the lower second branch duct 53 to the outdoor return air duct 40, finally entering the casing 11.

[0112] In this way, the warm air generated during heating flows from top to bottom within the indoor air outlet duct 30. Within the indoor air outlet duct 30, the warm airflow velocity is higher in the central area and relatively lower at the edges, with the overall airflow following a downward and outward parabolic trajectory. Thus, during heating, the indoor air outlet duct 30 operates in an upward intake and downward return mode, achieving a carpet-like heating and air distribution. This carpet-like heating and air distribution means that the warm airflow flows from top to bottom and gradually disperses, with the outlet area of ​​the warm airflow in the indoor air outlet duct 30 mainly concentrated and dispersed at the lower part of the room, allowing the warm air to be delivered to the user more quickly and directly.

[0113] With this setup, the connection status of the upper conversion duct 60 and the lower conversion duct 50 needs to be switched between cooling and heating modes. To achieve this, a three-way valve or movable baffle can be installed at the intersection of the outdoor supply duct 20, the lower branch duct 52, and the upper branch duct 62. Similarly, a three-way valve or movable baffle can be installed at the intersection of the upper main duct 61, the upper branch duct 62, and the upper second branch duct 63, and at the intersection of the lower main duct 51, the lower branch duct 52, and the lower second branch duct 53. This allows for the switching of the gas flow path via the three-way valve or movable baffle.

[0114] Figure 7 This is a schematic diagram of the indoor air outlet duct in a ducted air conditioner provided in an embodiment of this application. (Refer to...) Figure 7 As shown, the indoor air outlet duct 30 includes a duct shell 100, which is the outer casing of the indoor air outlet duct 30. The duct shell 100 includes a side plate 110 and a front panel 120, which together form an air outlet duct 101. The airflow entering the indoor air outlet duct 30 flows along the air outlet duct 101.

[0115] The side panel 110 can be a solid plate without holes, while the front panel 120 can have holes. The side panel 110 mainly serves a supporting function to ensure that the casing 100 has sufficient structural strength. The front panel 120 also serves a supporting function. At the same time, the front panel 120 is the exposed surface of the indoor air outlet duct 30. The indoor air outlet duct 30 supplies air into the room through the front panel 120, and the front panel 120 is used to improve the appearance of the indoor air outlet duct 30.

[0116] Taking the installation of indoor air outlet duct 30 in an indoor corner as an example, the cross-sectional shape of the duct shell 100 can be a right triangle. The side plates 110 of the duct shell 100 serve as the two right-angled sides of the right triangle, and the two side plates 110 can be respectively attached to the two walls of the corner. The panel 120 of the duct shell 100 serves as the hypotenuse of the right triangle, and the panel 120 faces the indoor space to supply air into the room.

[0117] For example, the cross-section of the casing 100 can be an isosceles right triangle. This ensures that the side plates 110 on both sides of the casing 100 have the same width, and the angles between the panel 120 and the two walls at the corners are the same. The air supply area of ​​the panel 120 expands evenly towards both walls, resulting in a larger overall air supply area and wider air supply range for the indoor air outlet duct 30, leading to better overall temperature regulation of the indoor space. Furthermore, the air supply area of ​​the panel 120 does not tilt towards any one wall, reducing or even eliminating interference from the wall on the airflow, preventing turbulence and eddies, ensuring smooth airflow from the indoor air outlet duct 30, and avoiding airflow loss that could affect its efficiency.

[0118] Continue to refer to Figure 7 The panel 120 of the casing 100 may include a decorative portion 121 and an air outlet portion. Along the width direction of the panel 120, the decorative portion 121 may be located in the middle area of ​​the panel 120, while the air outlet portions may be located on both sides of the decorative portion 121. The air outlet portion has air outlet holes that penetrate both sides of the panel 120 in the thickness direction. The air outlet holes connect the air outlet duct 101 inside the casing 100 with the indoor space, and the indoor air outlet duct 30 supplies air into the room through the air outlet holes. The decorative portion 121 may be a solid portion without holes, and its main function is decoration.

[0119] Therefore, the panel 120 of the casing 100 not only serves the function of air supply but also enhances the appearance of the indoor air outlet duct 30. By placing the air outlets on both sides of the decorative section 121, the panel 120 achieves better symmetry. Not only is the panel 120 more aesthetically pleasing, but the symmetrical airflow from both sides of the panel 120 also results in a more uniform air supply effect for the indoor air duct.

[0120] It should be noted that the cross-sectional shape of the casing 100 is generally an isosceles right triangle, which can refer to the extension line of the outer surface of the decorative part 121 and the side plate 110 forming a right isosceles triangle. The shape and structure of the air outlet can be flexibly designed according to the requirements of the air supply effect, and this embodiment does not impose specific restrictions on this.

[0121] In some embodiments, the decorative portion 121 of the panel 120 may be provided with a light strip (not shown in the figure), which emits light when powered. In this way, the light strip can serve as indoor lighting, providing an additional function for the indoor air duct 30 and making its functions more diverse. Furthermore, the light strip also serves a decorative function, illuminating the indoor air duct 30 itself and enhancing its aesthetics.

[0122] For example, the light strip can be installed in the same direction as the overall extension of the housing 100. When the housing 100 extends along the wall along the interior height direction, the light strip can also be installed along the interior height direction. In this way, the matching degree between the light strip and the housing 100 is higher, and the lines of the light strip after being lit are smooth and simple, which helps to improve the appearance of the indoor air outlet duct 30.

[0123] Regarding the placement of the light strip, as an example, the light strip can be placed on the front side of the decorative part 121 (the side surface of the decorative part 121 in the thickness direction and facing away from the side panel 110), and the light strip emits light in a forward-facing manner towards the front of the panel 120. For example, the light strip can be located on the front side of the decorative part 121 and near the two side edges in the width direction of the decorative part 121, and the light strip can be, for example, inserted into a light groove opened on the back side of the decorative part 121 (the side surface of the decorative part 121 in the thickness direction and facing towards the side panel 110).

[0124] As another example, the light strip can also be disposed on the two side walls of the decorative section 121 in the width direction, with the light strip emitting light laterally toward both sides of the panel 120. In this case, the light strip can emit light toward the two side walls, for example, illuminating light and shadow or patterns on the two side walls to enhance the lighting atmosphere effect of the light strip. For example, the light strip can be fitted into the light grooves opened in the inner side walls on both sides of the decorative section 121.

[0125] like Figure 7 As shown, the entire indoor air outlet duct 30 can be composed of multiple air outlet duct sections 31, with each air outlet duct section 31 arranged sequentially along the extension direction of the indoor air outlet duct 30. For example, each air outlet duct section 31 can be arranged sequentially along the corner of the wall in the indoor height direction. The indoor air outlet duct 30 is formed by sequentially splicing multiple air outlet duct sections 31, and each air outlet duct section 31 can include a side plate 110 and a front panel 120.

[0126] For example, the air outlet duct section 31 can be designed to have a uniform length, such as 1 meter. When installing the indoor air outlet duct 30, the number of air outlet duct sections 31 can be selected according to the indoor wall dimensions (e.g., wall height).

[0127] Furthermore, when the total length of each air outlet duct section 31 after sequential splicing does not match the dimensions of the indoor wall, decorative duct sections 32 can be added to both ends of the spliced ​​air outlet duct section 31. The number and length of the decorative duct sections 32 can be designed based on the difference between the dimensions of the indoor wall and the total length of each air outlet duct section 31, so that the overall length of the indoor air outlet duct 30 matches the dimensions of the wall.

[0128] Additionally, when the decorative pipe section 32 is installed between the air inlet end 30a of the indoor air outlet duct 30 and the air outlet pipe section 31, the decorative pipe section 32 needs to connect the air outlet pipe section 31 to the air inlet end 30a of the indoor air outlet duct 30. In this case, the decorative pipe section 32 can be a hollow pipe section, with both ends connected to the air inlet end 30a of the indoor air outlet duct 30 and the air outlet pipe section 31, respectively, so that the airflow entering from the air inlet end 30a of the indoor air outlet duct 30 can flow into the air outlet pipe section 31 through the decorative pipe section 32.

[0129] Figure 8 for Figure 7 A schematic diagram of the air outlet duct section in the central room. Figure 9 for Figure 8 A schematic diagram of the cross-section of the air outlet duct section.

[0130] Reference Figure 8 and Figure 9 As shown, the air outlet provided on the panel 120 of the casing 100 includes a first air outlet 122, which is located on both sides of the decorative part 121, and first air outlet holes 1221 are distributed on the first air outlet 122, for example, evenly distributed on the first air outlet 122. Figure 9 As indicated by the arrow in the diagram, the airflow flows along the air outlet duct 101 inside the casing 100 and can flow out from the first air outlet holes 1221 opened on the first air outlet 122 on both sides of the decorative part 121, so as to send air into the room through the first air outlet 122.

[0131] Furthermore, a first air-softening plate 200 is also provided inside the casing 100. The surface of the first air-softening plate 200 can be perpendicular to the extension direction of the air outlet duct 101, and the first air-softening plates 200 are spaced apart along the extension direction of the air outlet duct 101. Taking the indoor air outlet duct 30 extending along the wall in the indoor height direction as an example, the surface of the first air-softening plate 200 is perpendicular to the indoor height direction and parallel to the indoor plane direction, and the first air-softening plates 200 are spaced apart along the indoor height direction.

[0132] As the airflow flows along the air outlet duct 101, at least part of the airflow will pass through the first air softening plate 200. The first air softening plate 200 is provided with first air softening holes 210. The airflow passing through the first air softening plate 200 flows to the air outlet of the panel 120 after passing through the first air softening holes 210.

[0133] The obstruction effect of the first air softening plate 200 reduces the airflow velocity within the air outlet duct 101, preventing excessive airflow and providing a gentler, more comfortable airflow, thus improving the overall comfort of the indoor air outlet duct 30. Especially in cooling mode, this prevents strong cold air from blowing directly on users, thus avoiding air conditioning sickness. Furthermore, at least a portion of the airflow within the air outlet duct 101 flows forward through the first air softening holes 210 on each of the first air softening plates 200, preventing most or almost all of the airflow from flowing directly to the end of the air outlet duct 101 before being blown out from the air outlet. With the obstruction and guidance effect of each stage of the first air softening plate 200, the airflow can be blown out from the air outlets in various areas along the length of the indoor air outlet duct 30, improving the uniformity of the indoor air outlet duct 30's airflow.

[0134] For example, the first soft air holes 210 can be evenly distributed on the first soft air plate 200. This improves the uniformity of the soft airflow from the first soft air plate 200, thereby improving the uniformity of the airflow from the indoor air outlet duct 30. Furthermore, the pressure within the air outlet duct 101 is more balanced, preventing stress concentration and improving the reliability of the first soft air plate 200 and the duct housing 100. Additionally, it facilitates the design and manufacturing of the first soft air plate 200, making it more versatile.

[0135] For example, the first soft air holes 210 can be arranged in an array on the first soft air plate 200, and the row spacing and column spacing of the first soft air holes 210 can be equal, for example. In this way, the distribution of the first soft air holes 210 is more regular, and the surface of the first soft air plate 200 can be effectively utilized, increasing the density of the first soft air holes 210 and making the airflow in the air outlet duct 101 more dispersed.

[0136] Continue to refer to Figure 8 and Figure 9 The air outlet on panel 120 may further include a second air outlet 123, which is also located on both sides of decorative section 121. Second air outlets 123 are distributed with second air outlets 1231, for example, evenly distributed throughout the second air outlet 123. Figure 9 As indicated by the arrow in the image, the airflow flows along the air outlet duct 101, or it can flow out from the second air outlet holes 1231 opened in the second air outlet 123 on both sides of the decorative part 121, so as to send air into the room through the second air outlet 123.

[0137] By providing a first air outlet 122 and a second air outlet 123 on one side of the decorative section 121, an angle is formed between the first air outlet 122 and the second air outlet 123. This can be understood as the first air outlet 122, the second air outlet 123, and the extended line between the decorative section 121 and the side panel 110 forming a triangle, with the total length of the first air outlet 122 and the second air outlet 123 exceeding the length of this extended line. This increases the area of ​​the air outlets on the panel 120, thereby expanding the air outlet area of ​​the indoor air outlet duct 30 and improving its air delivery efficiency and effect.

[0138] The diameter of the first air outlet 1221 on the first air outlet 122 and the diameter of the second air outlet 1231 on the second air outlet 123 can be kept consistent. In this way, when the opening area ratio of the first air outlet 122 is similar to that of the second air outlet 123, the pressure and velocity of the airflow from the first air outlet 122 and the second air outlet are also similar, resulting in uniform airflow throughout the air outlet section, good balance, and high reliability.

[0139] It should be noted that, since the second air outlet 123 is located between the decorative part 121 and the first air outlet 122, the second air outlet 123 is closer to the middle area in the width direction of the panel 120. As mentioned above, the airflow velocity is greater in the central area of ​​the air outlet duct 101 and relatively lower in the edge area. Therefore, the airflow will preferentially (or more) be blown out through the second air outlet 123, affecting the air outlet effect of the first air outlet 122.

[0140] To improve the uniformity of airflow throughout the entire air outlet, in this embodiment, the second air outlet 123 can be located on the side of the decorative part 121 facing the side plate 110. That is, the second air outlet 123 can extend from the decorative part 121 towards the side plate 110. In this way, the end where the first air outlet 122 connects to the second air outlet 123 extends inward into the casing 100. In other words, from the end where the first air outlet 122 connects to the side plate 110 to the end where the first air outlet 122 connects to the second air outlet 123, the first air outlet 122 extends obliquely inward into the casing 100.

[0141] With this configuration, the first air outlet 122 is inclined inward toward the casing 100, and the junction of the first air outlet 122 and the second air outlet 123 is located inside the decorative section 121. This way, the end of the first air outlet 122 that connects to the second air outlet 123 is closer to the center of the air outlet duct 101, which increases the airflow to the first air outlet 122, making the airflow from the first air outlet 122 and the second air outlet 123 more balanced, resulting in better airflow uniformity across the entire air outlet section.

[0142] And, as Figure 9As indicated by the middle arrow, the first air outlet 122, inclined inwards towards the casing 100, has its air outlet direction inclined towards the decorative section 121 in the center of the panel 120. For the first air outlets 122 located on both sides of the decorative section 121, their air outlet directions are both inclined towards the central section. The indoor air outlet duct 30 is typically mounted against an indoor wall corner. The air outlet direction of the inwardly inclined first air outlet 122 faces away from the wall, preventing interference from the wall with the airflow of the first air outlet 122, ensuring smooth airflow, and avoiding turbulence and eddies.

[0143] In addition, such as Figure 9 As shown by the middle arrow, the air outlet direction of the second air outlet 123 is towards the first air outlet 122, and the airflow from the second air outlet 123 can converge with the airflow from the first air outlet 122. When the two airflows from different directions converge, the mutual friction between the gases can reduce the airflow velocity, slow down the overall airflow velocity of the air outlet, and make the air delivery from the indoor air outlet duct 30 more gentle and comfortable, enhancing the windless effect of the indoor air outlet duct 30.

[0144] For example, the second air outlet 123 can be perpendicular to the decorative part 121. When the decorative part 121 is subjected to an external force, the force can propagate along the plane of the second air outlet 123. The second air outlet 123 provides good support for the decorative part 121, and the second air outlets 123 located on both sides of the decorative part 121 can support and balance the decorative part 121. Therefore, the decorative part 121 and the second air outlet 123 have higher stress resistance, and the reliability of the indoor air outlet duct 30 is higher.

[0145] Continue to refer to Figure 8 and Figure 9 Furthermore, a second air-softening plate 300 can be installed inside the casing 100 of the indoor air outlet duct 30. The extension direction of the second air-softening plate 300 can be the same as the extension direction of the decorative part 121, and the second air-softening plate 300 can extend along the extension direction of the casing 100. Taking the indoor air outlet duct 30 extending along the wall in the indoor height direction as an example, the surface of the second air-softening plate 300 is parallel to the indoor height direction.

[0146] As the airflow flows along the air outlet duct 101, at least a portion of the airflow passes through the second air outlet 300 as it flows from the first air deflector 200 to the air outlet on the panel 120. The second air outlet 300 has second air deflector holes 310 distributed on it. The airflow passing through the second air outlet 300 flows through the second air deflector holes 310 and then flows to the air outlet on the panel 120, and is finally delivered outward from the air outlet on the panel 120.

[0147] like Figure 9As shown by the dotted arrow, most of the airflow along the air outlet duct 101 first passes through the first softening plate 200, then flows to the second softening plate 300, and finally is delivered outwards through the air outlet on the panel 120. Thus, the indoor air outlet duct 30 can provide three levels of softened airflow: the first softening plate 200 is equivalent to level one, the second softening plate 300 is equivalent to level two, and the air outlet on the air outlet is equivalent to level three. This enhances the softening effect of the indoor air outlet duct 30, enabling it to achieve an ultra-softened and ultra-comfortable airflow.

[0148] For example, the second soft air holes 310 can be evenly distributed on the second soft air plate 300 to improve the uniformity of the soft airflow of the second soft air plate 300, thereby improving the uniformity of the air supply of the indoor air outlet duct 30. Furthermore, the second soft air plate 300 experiences more balanced air pressure, resulting in higher reliability. Additionally, it facilitates the design and manufacturing of the second soft air plate 300, making it more versatile.

[0149] like Figure 9 As shown, as an example, the second airflow perforation 310 can perpendicularly penetrate both sides of the second airflow softening panel 300 in the thickness direction. Thus, after passing through the second airflow perforation 310, the airflow flows directly towards the panel 120, and then along a smooth arc path to the air outlets on both sides of the decorative panel. The longer flow path between the second airflow softening panel 300 and the air outlets reduces the airflow velocity, helping to improve the airflow softening effect of the indoor air outlet duct 30. Furthermore, the second airflow softening panel 300 has a simpler and more regular structure, facilitating its processing.

[0150] As another example, the central axis along the length of the second wind deflector 300 can be used as a baseline to design the second wind deflector 300 into zones. The second wind deflector holes 310 located on both sides of the central axis of the second wind deflector 300 are inclined towards the air outlets on both sides of the decorative part 121. Therefore, when airflow passes through the second wind deflector 300, it can guide the airflow to the air outlets on both sides, allowing the airflow to flow more accurately and quickly from the air outlets on both sides into the room.

[0151] In this way, the second air deflector 300 not only softens the airflow but also guides and diverts it, enhancing the orderliness of the airflow within the air outlet duct 101 and increasing the gas velocity within the duct. Consequently, it improves the air delivery efficiency of the indoor air outlet duct 30 and reduces the energy consumption of the ducted air conditioner.

[0152] As for the positions of the first air-softening plate 200 and the second air-softening plate 300 within the casing 100, such as Figure 8 or Figure 9As shown, the first wind deflector 200 can be connected to the side panel 110 and extend toward the panel 120, while the second wind deflector 300 can be close to the panel 120, so that the airflow in the air outlet duct 101 passes sequentially through the first wind deflector 200, the second wind deflector 300 and the air outlet on the panel 120.

[0153] Furthermore, a gap may exist between the first airflow deflector 200 and the second airflow deflector 300. The airflow guidance of the first airflow deflector 200 differs from that of the second airflow deflector 300, and the gap between them allows the airflow flowing from the first airflow deflector 200 to diffuse to the second airflow deflector 300. Moreover, the airflow forms a certain angle with the second airflow deflector 300 as it flows towards it, allowing the airflow to pass smoothly through the second airflow deflector orifice 310. This avoids the problem of insufficient gap between the first airflow deflector 200 and the second airflow deflector 300, which could potentially affect the smoothness of airflow. It also prevents the airflow exiting from the first airflow deflector orifice 210 from rubbing against the surface of the second airflow deflector 300, thus avoiding noise inside the pipe.

[0154] Furthermore, the gap between the first airflow deflector 200 and the second airflow deflector 300 allows some airflow to bypass the first airflow deflector 200 and pass directly through the second airflow deflector hole 310 on the second airflow deflector 300 before exiting from the air outlet on the panel 120. This increases the gas velocity within the air outlet duct 101 and improves the air delivery efficiency of the indoor air outlet duct 30.

[0155] Continue to refer to Figure 8 and Figure 9 In this embodiment, the second airflow deflector 300 can be connected between the two second air outlets 123. The air inlet surface of the second airflow deflector 300 does not extend beyond the end of the first air outlet 122 that is connected to the second air outlet 123. That is, the second airflow deflector 300 is located within the space of the second air outlet 123, and the air inlet surface of the second airflow deflector 300 is farther than the air inlet surface of the first air outlet 122.

[0156] With this configuration, the airflow in the central area of ​​the air outlet duct 101 is large and fast. Most of the airflow will pass through the second softening plate 300 and flow to the second air outlet 123, eventually exiting from the second air outlet 123. As mentioned earlier, most of this airflow passes through the first softening plate 200, the second softening plate 300, and the second air outlet 123 in sequence, achieving a three-stage softening effect. This effectively reduces the airflow velocity exiting from the central area of ​​the air outlet duct 101, truly achieving a softening effect.

[0157] The airflow at the edge of the air outlet duct 101 has a relatively small flow rate and low velocity. With the second air outlet 123 installed, a small portion of the airflow will flow into the room through the first air outlet 122 at the edge. By ensuring that this airflow only passes through the first air deflector 200 and the first air outlet 122, a two-stage air deflection is achieved. This avoids excessively restricting the flow rate and velocity of this airflow, ensuring that the first air outlet 122 has an air volume and velocity comparable to the second air outlet 123.

[0158] When the second air softening plate 300 is disposed on the air inlet side of the second air outlet 123, the diameter of the second air softening hole 310 on the second air softening plate 300 can be larger than the diameter of the second air outlet hole 1231 on the second air outlet 123. As the airflow passes through the second air softening plate 300 and the second air outlet 123, the airflow velocity gradually decreases, achieving a gradual softening of the airflow in the indoor air outlet duct 30. Conversely, if the diameter of the second air softening hole 310 is smaller than the diameter of the second air outlet hole 1231, the second air softening plate 300 may restrict the airflow, and in severe cases, may even affect the effective airflow of the second air outlet 123.

[0159] Continue to refer to Figure 8 and Figure 9 A partition plate 400 may also be provided inside the casing 100 of the indoor air outlet duct 30. The partition plate 400 connects the second air outlet 123 and the corresponding side plate 110. In other words, one end of the partition plate 400 is connected to the side plate 110, and the other end of the partition plate 400 is connected to the second air outlet 123. A vent 410 is provided on the partition plate 400. The vent 410 can be arranged sequentially at intervals along the extension direction of the casing 100. The vent 410 connects the central area where the first air softener 200 is located with the edge area where the first air outlet 122 is located.

[0160] On one hand, the partition plate 400 connects the second air outlet 123 and the side plate 110, and the two work together to provide complete support between the decorative part 121 and the side plate 110. The partition plate 400, the second air outlet 123, and the second wind deflector 300 form a frame support structure between the decorative part 121 and the side plate 110, which can improve the reliability of the indoor air outlet duct 30 and extend its service life.

[0161] When designing the indoor air duct 30, the side plate 110 of the duct shell 100 and the first air outlet 122 on the panel 120 can be designed as an integral structure, as can the partition plate 400, the second air outlet 123, and the second air softening plate 300. Since the decorative part 121 needs to transmit light emitted from the light strip, it is typically made of a different material than other parts of the duct shell 100 and the first and second air softening plates 200 and 300. Therefore, the decorative part 121 can be a separate component, and an integral connecting plate 124 can be designed between the two second air outlets 123. The connecting plate 124 serves as the mounting base for the decorative part 121, which can be glued or attached to the surface of the connecting plate 124 using screws, bolts, or other fasteners.

[0162] On the other hand, the partition plate 400 divides the pipe shell 100 into multiple vents 410 along its extension direction. The baffle portion 420 between adjacent vents 410 has a diversion function, making it easier for airflow to flow out from the vents 410 on both sides of the baffle portion 420. This reduces the viscosity effect between gases, preventing most of the gas from flowing to the end of the first air outlet 122 and then flowing out, so that a suitable amount of airflow flows out in each region along the length of the first air outlet 122, thereby improving the uniformity of airflow from the first air outlet 122.

[0163] For example, the extending direction of the partition plate 400 can be the same as the extending direction of the second air outlet 123. In other words, the partition plate 400 can extend along the extending direction of the second air outlet 123, and the partition plate 400 can be considered as an extension of the second air outlet 123. In this way, the partition plate 400 and the second air outlet 123 have good integrity and consistency, which can improve the support and reliability of both. For example, the partition plate 400 can also be perpendicular to the decorative part 121.
