Description

Technical Field

[0001] This article relates to air conditioning equipment technology, particularly an air outlet frame assembly, duct unit, and air conditioner. Background Technology

[0002] Ductless air conditioners are typically installed in ceiling-mounted systems using either bottom or side air outlets. The air outlets are paired with decorative panels to guide / diffuse airflow, achieving cooling / heating functions. Decorative panels are popular due to their customizable length and width, allowing for better coordination and a more sophisticated look with home décor, making them the most common installation method. However, existing technology has the following problems:

[0003] 1. For side-exit air supply solutions: The air guide grille on the engineering panel cannot be automatically adjusted, so the hot air cannot reach the ground when heating. Even if the tilt angle of the air guide grille is set to the maximum downward, it is still impossible to deliver hot air directly below the duct unit. This results in problems such as a large blind spot in air supply, large temperature differences in different areas of the room, and poor heating effect.

[0004] 2. Regarding the following air outlet design: When cooling, the cold air blows directly onto the user, resulting in a poor user experience. Utility Model Content

[0005] This application provides an air outlet frame assembly, including: an air outlet bracket having a first air outlet oriented along a first direction; and a plurality of switch doors arranged sequentially along a third direction and swayably mounted on the air outlet bracket at the first air outlet, wherein the plurality of switch doors are configured to jointly close and jointly open the first air outlet, and the first direction intersects with the third direction.

[0008] In some exemplary embodiments, the plurality of hinged portions include two sets of hinged portions, which are respectively disposed at the two ends of the opening wall of the first air vent in a third direction, and the plurality of switch doors are two switch doors, which are respectively hinged to the two sets of hinged portions.

[0009] In some exemplary embodiments, the air outlet bracket further has an inspection port and a second mounting portion, the first air outlet and the inspection port are arranged sequentially in a second direction, and the second mounting portion is located on the first side of the inspection port in the first direction; the air outlet frame assembly further includes: a rotation drive member, fixedly disposed in the second mounting portion and fixedly connected to the plurality of the switch doors, the rotation drive member being configured to drive the plurality of switch doors to swing, and the first direction, the second direction and the third direction intersect each other.

[0010] In some exemplary embodiments, both the second mounting portion and the rotary drive member include multiple components. The multiple rotary drive members are fixedly disposed in the multiple second mounting portions and fixedly connected to the multiple switch doors in a one-to-one correspondence. The multiple rotary drive members are configured to drive the multiple switch doors to swing in a one-to-one correspondence.

[0011] In some exemplary embodiments, the air outlet bracket further has a first mounting portion located on a first side of the first air outlet in a first direction, and the first mounting portion and the first air outlet are arranged sequentially in a second direction. The first mounting portion is configured to fix the heat exchanger assembly, and the first direction, the second direction, and the third direction intersect each other.

[0012] In some exemplary embodiments, the air outlet bracket includes a first frame plate and a second frame plate connected to each other in a folded structure. In the first direction, the second frame plate is located on a first side of the first frame plate, and in the third direction, the second frame plate is located on a sixth side of the first frame plate. The first air outlet is located on the first frame plate, and the first mounting part is located on the first frame plate and / or the second frame plate.

[0013] In some exemplary embodiments, the first mounting portion includes two groups, with the first air vent located between the two groups of the first mounting portions in the second direction, and each group of the first mounting portions includes at least one of a plug-in connection portion, a positioning portion, a snap-fit ​​connection portion, and a screw connection portion.

[0014] In some exemplary embodiments, the air outlet bracket is further provided with a second air inlet, the second air inlet being oriented along the third direction. In the first direction, the second air inlet is located on the first side of the first air inlet, and in the third direction, the second air inlet is located on the fifth side of the first air inlet. The switch door adjacent to the second air inlet in the third direction is configured to be able to open and close the second air inlet.

[0015] This application also provides a duct air conditioner, including a housing and an air outlet frame assembly as described in any of the above embodiments. The housing is provided with a first air outlet, the air outlet frame assembly is disposed inside the housing, and the first air outlet is located inside the first air outlet.

[0016] In some exemplary embodiments, a plurality of the switch doors are located on the side of the first air vent facing the interior of the housing. A second air vent is also provided on the side of the first air vent facing the interior of the housing in the first direction. The second air vent is also located on the fifth side of the first air vent in the third direction. The switch doors adjacent to the second air vent in the third direction are configured to be able to open and close the second air vent.

[0017] This application also provides an air conditioner, including the ducted air conditioner described in any of the above embodiments.

[0018] The technical solution provided in this application embodiment involves an air outlet frame assembly applied to a ducted air conditioner. The ducted air conditioner also has a second air inlet. The second air inlet is located on the first side (e.g., the rear side) of the first air inlet in a first direction (e.g., the front-to-back direction), and on the fifth side (e.g., the lower side) of the first air inlet in a third direction (e.g., the up-down direction). When multiple doors jointly close the first air inlet, the second air inlet is in an open state. At this time, air can blow from the second air inlet towards the direct lower part of the ducted air conditioner. Since multiple doors jointly close the first air inlet, condensation will not occur at the first air inlet. The question is: If the second air vent is closed by a third-party switch door near the second air vent, then the first air vent is at least partially open. At this time, air can be blown from the first air vent toward the front of the duct unit, and the switch door at the bottom closes the second air vent. In this way, the switch door at the bottom will not cause condensation at the second air vent. That is, the duct unit, together with the engineering panel, can deliver hot and cold air downwards, and can also deliver hot and cold air forwards. This can reduce the blind spot of air delivery, reduce the temperature difference between different areas of the room, improve the user's comfort when blowing hot air, and provide a better user experience.

[0019] Other features and advantages of this application will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the application. Other advantages of this application can be realized and obtained by means of the solutions described in the description and the accompanying drawings. Attached Figure Description

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0033] The ducted air handling unit provided in the embodiments of this application, such as Figure 1and Figure 2 As shown, it includes a housing 600 and an integrated assembly, the integrated assembly being disposed within the housing 600. Figures 1 to 7 As shown, the integrated assembly includes an air outlet frame assembly and a heat exchanger assembly 100, with the heat exchanger assembly 100 located on the side of the air outlet frame assembly facing the interior of the housing 600. The air outlet frame assembly includes an air outlet bracket 200, which has a first air passage 211 and a first mounting portion 230. In a first direction, the first mounting portion 230 is located on the first side of the first air passage 211 (the first side of the first air passage 211 faces the interior of the housing 600). In a second direction, the first mounting portion 230 and the first air passage 211 are sequentially arranged. In the first direction, the heat exchanger assembly 100 is located on the first side of the first air passage 211 and fixed to the first mounting portion 230. The first air passage 211 is opposite to the side of the heat exchanger in the heat exchanger assembly 100, and the first and second directions intersect. The housing 600 is provided with a first air inlet and a second air inlet. The first air outlet 211 is located inside the first air inlet. The heat exchanger assembly 100 is located between the second air inlet and the air outlet bracket 200. An air stream is formed inside the housing 600, which blows from the second air inlet through the heat exchanger to the first air outlet 211. The first direction is the front-to-back direction, the second direction is the left-to-right direction, and the first side is the rear side.

[0034] The integrated component is used in duct air conditioners. The heat exchanger assembly 100 and the air outlet bracket 200 are both located inside the housing 600. The first air outlet 211 is located inside the first air outlet. The air outlet bracket 200 is fixedly connected to the heat exchanger assembly 100 through the first mounting part 230. In this design, the air outlet bracket 200 is made of plastic, so the first mounting part 230 can be easily designed as a plug-in connection part, a positioning part, a snap-fit ​​connection part, or a screw connection part, etc. This design simplifies the fixing method between the heat exchanger assembly 100 and the air outlet bracket 200. Moreover, after the heat exchanger assembly 100 and the air outlet bracket 200 are assembled into an integrated component, the integrated component is installed into the housing 600 as a whole, which reduces the assembly difficulty of the heat exchanger assembly 100 and the air outlet bracket 200 inside the housing 600.

[0035] In some examples, such as Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the air outlet frame assembly also includes a rotary drive component 300 and a switch door 400. The air outlet bracket 200 also has an inspection port 213 and a second mounting portion 240. The first air outlet 211 and the inspection port 213 are arranged sequentially in a second direction. In the first direction, the second mounting portion 240 is located on the first side of the inspection port 213 and is configured to fix the rotary drive component 300. The first air outlet 211 is configured to mount the swingable switch door 400. The rotary drive component 300 is positioned opposite the inspection port 213 and is used to drive the switch door 400 to swing. The rotary drive component 300 drives the switch door 400 to swing, thereby opening and closing the first air outlet 211. In case of a malfunction of the rotary drive component 300, it can be disassembled and repaired through the inspection port 213, making the disassembly and repair process of the rotary drive component 300 simpler.

[0036] It could be that the second mounting part 240, the rotary drive component 300, and the door opening / closing unit 400 are arranged as a set; or it could be, as... Figures 2 to 4 As shown, two sets of the second mounting part 240, the rotary drive component 300, and the switch door 400 are arranged, with the two switch doors 400 arranged sequentially in the vertical direction and opening and closing the first air passage 211 together; or, three sets of the second mounting part 240, the rotary drive component 300, and the switch door 400 are arranged, with the three switch doors 400 arranged sequentially in the vertical direction and opening and closing the first air passage 211 together; or, one inspection port 213 is included and located on the left side of the first air passage 211; or, one inspection port 213 is included and located on the right side of the first air passage 211; or, two inspection ports 213 are included and located on the left and right sides of the first air passage 211, etc.; all of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this utility model, and will not be elaborated here, and should all fall within the protection scope of this application.

[0037] In some embodiments, such as Figure 4As shown, the ducted air conditioner also includes a water collection tray 500, which is located inside the housing 600 and below the heat exchanger assembly 100. A second air outlet 510 is provided at the front of the water collection tray 500, located below and behind the first air outlet 211. A rotary drive unit 300 drives the opening and closing door 400 to swing, which can also open and close the second air outlet 510. That is, the opening and closing door 400 can simultaneously open the first air outlet 211 and the second air outlet 510 to allow air to flow from both outlets simultaneously, or it can selectively open only one outlet to allow air to flow from either outlet. Alternatively, during heating, the door 400 opens the second air vent and closes the first air vent 211, allowing hot air to blow downwards from the second air vent, thus quickly bringing the hot air to the ground. Conversely, during cooling, the door 400 closes the second air vent and opens the first air vent 211, allowing cold air to blow forward from the first air vent 211, preventing cold air from blowing directly on people. Or, during cooling, the door 400 first opens both the first and second air vents simultaneously, and after a set time, closes the second air vent and opens the first air vent 211. When the first air vent 211 is opened, cold air is blown into the room simultaneously from both the first and second air vents, achieving rapid cooling. After a set time, the cold air is then blown forward from the first air vent 211, preventing the cold air from blowing directly on people. Alternatively, the user can control the opening and closing of the door 400 as needed, such as opening the second air vent and closing the first air vent 211 when cooling is required. All of the above can achieve the purpose of this application, and their intent does not deviate from the design concept of this utility model. They will not be elaborated further here, and all should fall within the protection scope of this application.

[0038] In other embodiments, such as Figure 8 and Figure 9As shown, the air outlet bracket 200 also has a second air passage 280. In a first direction, the second air passage 280 is located on the first side of the first air passage 211. In a third direction, the second air passage 280 is located on the fifth side (i.e., the lower side) of the first air passage 211 (in this design, the second air passage 280 is located on the air outlet bracket 200). The first air passage 211 discharges air forward, and the second air passage 280 discharges air downward. The third direction refers to the vertical direction, and the fifth side refers to the lower side. Furthermore, the rotary drive 300 drives the opening and closing door 400 to swing, which also allows the opening and closing door 400 to open and close the second air passage 280. The door 400 can simultaneously open the first air vent 211 and the second air vent 280 to allow air to flow from both vents at the same time. Alternatively, the door 400 can selectively open only one of the two air vents to allow air to flow from only one. For example, during heating, the door 400 opens the second air vent 280 and closes the first air vent 211, allowing hot air to blow downwards from the second air vent 280, achieving rapid airflow to the ground. Conversely, during cooling, the door 400 closes the second air vent 280 and opens the first air vent 211, allowing cold air to blow forward from the first air vent 211, preventing cold air from blowing directly on people. Finally, during cooling, the door 400 first simultaneously opens both the first air vent 211 and the second air vent 280, and then closes the second air vent after a set time. 280. When the first air vent 211 is opened, cold air is blown into the room simultaneously from the first air vent 211 and the second air vent 280, achieving rapid cooling of the room. After a set time, the cold air is then blown forward from the first air vent 211 to avoid the cold air blowing directly on people. Alternatively, the user can control the opening and closing of the door 400 as needed, such as opening the second air vent 280 and closing the first air vent 211 when cooling. All of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this utility model. They will not be elaborated here and should all fall within the protection scope of this application.

[0039] In some examples, the first air vent 211 is provided with multiple sets of hinges 212 at third-direction intervals, and multiple doors 400 are connected to the multiple sets of hinges 212 in a one-to-one correspondence. For example Figure 4 and Figure 7As shown, the multiple sets of hinges 212 include two sets of hinges 212, each set located at one end of the first air vent 211 in the third direction. Two second mounting parts 240 are included, each corresponding one-to-one with one of the two sets of hinges 212. The two sets of hinges 212 are configured to hingely connect the two doors 400. Each set of hinges 212 includes multiple hinges spaced apart (e.g., evenly distributed) in the left-right direction, which better supports the doors 400 and prevents local bending deformation. The two doors 400 are configured to open and close the first air vent 211 simultaneously, and the lower door 400 is configured to open and close the second air vent 510. The first air vent 211 is larger in the vertical direction than the second air vent 510 is in the front-back direction. When the first air vent 211 is closed, the lower door 400 is larger in the vertical direction than the upper door 400. The upper ends of the upper door 400 and the lower ends of the lower door 400 are hinged to the two sets of hinges 212. To prevent air leakage at the hinges, sealing sponge is provided between the hinge ends of the two doors 400 and the wall of the first air vent 211 in the vertical direction.

[0040] It is possible that the upper switch door 400 has a first position and a second position, and the lower switch door 400 has a third position, a fourth position, and a fifth position. For example... Figure 2 As shown, when the upper switch door 400 is in the second position and the lower switch door 400 is in the fourth position, both switches door 400 together close the first air vent 211, and the lower switch door 400 opens the second air vent 510; Figure 4 As shown, when the upper switch door 400 is in the first position and the lower switch door 400 is in the third position, both switch doors 400 open the first air vent 211 together, and the lower switch door 400 closes the second air vent 510. When the upper switch door 400 is in the first position and the lower switch door 400 is in the fifth position (the fifth position is between the third and fourth positions), both switch doors 400 open the first air vent 211 together, and the lower switch door 400 opens the second air vent 510.

[0041] In some examples, such as Figure 2 , Figure 4 and Figure 7As shown, the first air vent 211 has a first annular mating surface 250 on its opening wall. The first annular mating surface 250 faces the first side (i.e., the rear side) of the first air vent 211 in the first direction. The first annular mating surface 250 is configured to cooperate with the two switch doors 400 to close the first air vent 211. At this time, the adjacent ends of the two switch doors 400 are sealed by overlapping (a sealing sponge can be added here to improve the sealing effect during overlapping). This can prevent air leakage at the first air vent 211 when cold air is discharged from the second air vent 510, which would cause condensation and whistling. Moreover, when air is discharged only from the second air vent 510, the overlapping part of the adjacent ends of the two switch doors 400 is pressed tightly by the wind pressure formed by the wind jet blown inside the housing 600. The periphery of the two switch doors 400 is pressed tightly by the wind pressure on the first annular mating surface 250. This makes the two switch doors 400 better at closing the first air vent 211. The first air vent 211 is equipped with a reinforcing rib 270 erected along the front-to-back direction. The shape of the rear end face of the reinforcing rib 270 matches the shape of the side faces of the two switch doors 400. When the upper switch door 400 is in the second position and the lower switch door 400 is in the fourth position, the front sides of the two switch doors 400 abut against the rear end face of the reinforcing rib 270. Multiple reinforcing ribs 270 are arranged at intervals in the left-to-right direction, which can better improve the structural strength of the integrated component. The upper hinge portion 212 is located on the upper part of the first annular mating surface 250, and the lower hinge portion 212 is located on the lower part of the first annular mating surface 250.

[0042] In some examples, such as Figure 4 As shown, the second air vent 510 has a second annular mating surface 260 on its opening wall. On the sixth side (i.e., the upper side) of the second annular mating surface 260 facing the second air vent 510, the second annular mating surface 260 is configured to cooperate with the lower switch door 400 to seal the second air vent 510. This prevents air leakage at the second air vent 510, which could lead to condensation and whistling noise, when cold air exits from the first air vent 211. Similarly, when air exits only from the first air vent 211, the lower switch door 400 is pressed against the second annular mating surface 260 by the air pressure generated by the airflow blown from inside the housing 600. This further enhances the sealing effect of the lower switch door 400 on the second air vent 510.

[0043] Alternatively, the first mounting part 230 may include a set and be disposed on the rear left side of the first air outlet 211; or the first mounting part 230 may include a set and be disposed on the rear right side of the first air outlet 211; or it may be as follows: Figures 5 to 7As shown, the first mounting part 230 includes two sets, and the first air outlet 211 is located between the two sets of the first mounting parts 230. The heat exchanger assembly 100 is fixedly connected to the two first mounting parts 230 one by one at both ends in the left and right directions. All of the above can achieve the purpose of this application. Its purpose has not departed from the design concept of this utility model, and will not be repeated here. All of them should be within the protection scope of this application.

[0044] In some examples, such as Figures 5 to 7 As shown, each group of first mounting portions 230 includes at least one of a plug-in connection portion, a positioning portion, a snap-fit ​​connection portion, and a screw-fit connection portion. This could be, for example... Figure 2 , Figure 3 , Figures 5 to 7 As shown, the first mounting part 230 includes a plug-in connection part, a positioning part, and a screw connection part. The plug-in connection part is configured as a plug rib arranged in the vertical direction, the positioning part is configured as a positioning groove, and the screw connection part is configured as a screw hole. The heat exchanger assembly 100 includes a heat exchanger 110 and two mounting brackets 120. The two mounting brackets 120 are connected to the two side plates of the heat exchanger 110 one-to-one. Each mounting bracket 120 is provided with a slot, a positioning protrusion, and a through hole. The slot is inserted into the plug rib from bottom to top, the positioning protrusion is inserted into the positioning groove, and the screw passes through the through hole and is screwed into the screw hole. In this way, when the air duct machine is subjected to a drop test, the mounting bracket 120 of the heat exchanger assembly 100 will not move relative to the air outlet bracket 100.

[0045] In some examples, such as Figures 3 to 9 As shown, the air outlet bracket 200 includes a first bracket plate 210 and a second bracket plate 220 connected in a folded structure. In a first direction, the second bracket plate 220 is located on the first side (i.e., the rear side) of the first bracket plate 210, and in a third direction, the second bracket plate 220 is located on the sixth side (i.e., the upper side) of the first bracket plate 210. A first air outlet 211, an inspection port 213, and a second mounting part 240 are located on the first bracket plate 210, and a first mounting part 230 is located on the first bracket plate 210 and / or the second bracket plate 220. Alternatively, the plug-in connection part may be located on the first bracket plate 210, the positioning part may be located on the second bracket plate 220, and the screw hole may be located at the lower end of the plug-in connection part and on the second bracket plate 220. Both the first bracket plate 210 and the second bracket plate 220 are connected to the housing 600, thus enabling the air outlet bracket 200 to be securely fixed within the housing 600.

[0046] The air conditioner provided in this application embodiment (not shown in the figure) includes the ducted air conditioner described in any of the above embodiments.

[0047] This air conditioner possesses all the advantages of the ducted air conditioner provided in any of the above embodiments, which will not be repeated here.

[0048] In summary, the technical solution provided in this application integrates components for use in ducted air conditioners. Both the heat exchanger assembly and the air outlet bracket are housed within the casing. The first air outlet is located within the first air inlet. The air outlet bracket is fixedly connected to the heat exchanger assembly via a first mounting portion. In this solution, the air outlet bracket is made of plastic, allowing the first mounting portion to be easily designed as a plug-in connection, positioning part, snap-fit ​​connection, or screw connection, etc. This solution simplifies the connection between the heat exchanger assembly and the air outlet bracket. Furthermore, after assembling the heat exchanger assembly and the air outlet bracket into an integrated assembly, the entire integrated assembly is installed within the casing, reducing the assembly difficulty of the heat exchanger assembly and the air outlet bracket within the casing.
