Description

Technical Field

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

[0002] Some down-draft ducted air conditioners, such as Figure 1 As shown, its base plate 110 is equipped with a return air vent 15, through which indoor air enters the ducted air unit. In the down-flow ducted air unit, the connecting pipes (including the first refrigerant supply pipe 41 and the second refrigerant supply pipe 43) are wrapped with anti-vibration adhesive 42 to achieve a vibration reduction effect. The pipes contain electronic components such as electromagnetic control valves (not shown in the figure), and the area where the pipes are located is in the return air path. This means that if the electronic components accidentally catch fire and the anti-vibration adhesive 42 fails to meet fire resistance requirements, a large amount of smoke may enter the impeller of the fan assembly 2 along the return air path (the smoke flow path is as follows). Figure 1 (As shown by the middle arrow), thus causing the smoke emission to exceed the standard and fail to meet the UL certification smoke emission requirements. Summary of the Invention

[0003] The main objective of this application is to provide a ducted air conditioner that can reduce the amount of smoke entering the impeller due to accidental fires of electronic components, thereby meeting fire prevention requirements.

[0017] The duct unit also includes a first water receiving tray disposed within the housing. The first water receiving tray is located below the piping assembly and is configured to receive condensate from the piping assembly.

[0018] The fireproof isolation component includes a vertically arranged first fireproof partition, the lower end of which abuts against the first water receiving tray.

[0019] In some exemplary embodiments, the piping assembly includes a first refrigerant delivery pipe and a second refrigerant delivery pipe, the first ends of which both extend toward the fan mounting cavity;

[0020] The fireproof isolation component further includes a vertically arranged second fireproof partition.

The first side of the first fireproof partition near the second fireproof partition has two first notches, and the second side of the second fireproof partition near the first fireproof partition has two second notches. The two first notches and the two second notches cooperate to form two perforations.

[0052] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0053] like Figures 2 to 12 As shown in the figure, this application provides a duct air conditioner, including a housing 1 and a fireproof isolation component 5.

[0054] The housing 1 is provided with a return air inlet 15, a return air cavity connected to the return air inlet 15, an air supply outlet 16, and an air supply cavity 18 connected to the air supply outlet 16. The return air cavity is also connected to the air supply cavity 18, so that the return air inlet 15, the return air cavity, the air supply cavity 18 and the air supply outlet 16 are connected in sequence.

[0055] The return air cavity includes a fan mounting cavity 17 for mounting the fan assembly 2 and a piping mounting cavity 19 for mounting the piping assembly 4. An indoor heat exchanger can be installed in the supply air cavity 18. The indoor heat exchanger can be connected to the piping assembly 4 and, through the piping assembly 4, connected to the refrigerant piping of the outdoor unit of the air conditioner. Refrigerant can flow into the indoor heat exchanger via the piping assembly 4. After heat exchange in the indoor heat exchanger, the refrigerant can flow out of the indoor heat exchanger and flow back into the piping assembly 4.

[0056] When the fan assembly 2 is working, indoor air can enter the return air chamber from the return air inlet 15 and flow into the supply air chamber 18 to exchange heat with the indoor heat exchanger in the supply air chamber 18. After heat exchange, the air can be discharged from the air duct unit from the supply air inlet 16 and returned to the room to achieve cooling or heating of the indoor air.

[0057] like Figure 3 , Figure 5-Figure 8 As shown, the fireproof isolation element 5 is disposed on the side of the piping installation cavity 19 near the fan installation cavity 17 to at least partially separate the piping installation cavity 19 and the fan installation cavity 17.

[0058] The side of the piping installation cavity 19 closest to the fan installation cavity 17 is connected to the fan installation cavity 17. A fireproof isolation component 5 is installed on the side of the piping installation cavity 19 closest to the fan installation cavity 17. The fireproof isolation component 5 can at least partially isolate the piping installation cavity 19 and the fan installation cavity 17. That is, the fireproof isolation component 5 can at least partially isolate the communication channel between the piping installation cavity 19 and the fan installation cavity 17. In this way, when the electronic components of the piping assembly 4 accidentally catch fire, the smoke generated by the fire can be reduced or even prevented from entering the fan installation cavity 17 and the fan assembly 2, so as to ensure that the smoke generation meets the regulatory requirements and fire protection requirements.

[0059] In some exemplary embodiments, the housing 1 includes a first housing wall with a return air inlet 15, a piping mounting cavity 19 and a fan mounting cavity 17 arranged side by side and in an orientation parallel to the plane of the first housing wall.

[0060] The first shell wall of the housing 1 is provided with a return air inlet 15. The piping installation cavity 19 and the fan installation cavity 17 are arranged side by side and their arrangement direction is parallel to the plane where the first shell wall is located. That is, the piping installation cavity 19 and the fan installation cavity 17 are arranged on a plane parallel to the first shell wall, so that the return air inlet 15 can be directly connected to both the piping installation cavity 19 and the fan installation cavity 17. In this way, when a fireproof isolation component 5 is installed on the side of the piping installation cavity 19 near the fan installation cavity 17, a portion of the air entering from the return air inlet 15 can directly enter the fan installation cavity 17 and flow through the air supply cavity 18 and the air supply outlet 16 in sequence, so as to avoid the fireproof isolation component 5 from having too much impact on the overall air volume of the duct air conditioner.

[0061] In some exemplary embodiments, such as Figure 3 , Figure 5 , Figure 7 , Figures 9-10 As shown, the first shell wall is the bottom wall 110 of the shell, and the piping installation cavity 19 and the fan installation cavity 17 are arranged in an L-shape on the horizontal plane.

[0062] The return air vent 15 is located on the bottom wall 110 of the housing 1, making the ducted air unit a bottom return air type ducted air unit. Of course, the return air vent 15 can also be located on other walls of the housing 1 other than the bottom wall 110, such as the front wall 11, rear wall 12, left wall 13, right wall 14, etc.

[0063] In some exemplary embodiments, such as Figures 2-3 , Figure 5 , Figure 7 , Figures 9-10 As shown, the air outlet 16 can be located on the front wall 11 of the housing 1, the fan mounting cavity 17 can be located on the rear side of the air supply cavity 18, and the piping mounting cavity 19 can be located on the left or right side of the air supply cavity 18.

[0064] The air supply cavity 18 is located on the front side near the fan mounting cavity 17 and near the air outlet 16 of the front wall 11 of the housing 1, so that the air supply cavity 18 can communicate with the air outlet 16; the piping mounting cavity 19 is located on the left or right side of the air supply cavity 18, so that the piping mounting cavity 19 is adjacent to the air supply cavity 18, so that the piping assembly 4 in the piping mounting cavity 19 can be connected to the indoor heat exchanger in the air supply cavity 18.

[0065] Of course, the positions of the air outlet 16, the fan mounting cavity 17, the piping mounting cavity 19 and the air supply cavity 18 are not limited to the above, and can be adjusted according to actual needs. For example, the air outlet 16 can be set on the rear wall 12, left wall 13, right wall 14 of the housing 1, etc.

[0066] In some embodiments, such as Figure 3 As shown, the fireproof isolation component 5 is disposed on the side of the piping installation cavity 19 near the first shell wall to partially separate the piping installation cavity 19 and the fan installation cavity 17.

[0067] Fireproof isolation element 5 is disposed on the side of the piping installation cavity 19 near the first shell wall, and there is a gap between the fireproof isolation element 5 and the cavity wall of the piping installation cavity 19 away from the first shell wall. When the first shell wall is the bottom wall 110 of the shell 1, the fireproof isolation element 5 can be disposed on the lower side of the piping installation cavity 19, and there is a gap between the fireproof isolation element 5 and the upper cavity wall of the piping installation cavity 19. This allows the fireproof isolation element 5 to partially isolate the connecting channel between the piping installation cavity 19 and the fan installation cavity 17, thereby reducing the amount of smoke entering the fan installation cavity 17 and the fan assembly 2 in the event of an accidental fire involving the electronic components of the piping assembly 4, ensuring that the smoke generation meets regulatory requirements.

[0068] Compared to placing the fireproof isolation component 5 on the side of the piping installation cavity 19 away from the first shell wall, placing the fireproof isolation component 5 on the side of the piping installation cavity 19 closer to the first shell wall makes the fireproof isolation component 5 closer to the return air outlet 15, which can reduce the amount of smoke entering the fan installation cavity 17 and the fan assembly 2 when electronic components accidentally catch fire.

[0069] In some embodiments, such as Figure 3 As shown, the piping assembly 4 includes a first refrigerant delivery pipe 41 and a second refrigerant delivery pipe 43. The first ends of both the first refrigerant delivery pipe 41 and the second refrigerant delivery pipe 43 extend beyond the fireproof isolation member 5 and toward the fan mounting cavity 17. The first end of the first refrigerant delivery pipe 41 is closer to the first shell wall than the first end of the second refrigerant delivery pipe 43. When the first shell wall is the bottom wall 110 of the shell 1, the first end of the first refrigerant delivery pipe 41 may be lower than the first end of the second refrigerant delivery pipe 43.

[0070] The second ends of the first refrigerant delivery pipe 41 and the second refrigerant delivery pipe 43 are both connected to the indoor heat exchanger, so that the first refrigerant delivery pipe 41 and the second refrigerant delivery pipe 43 are both connected to the indoor heat exchanger.

[0071] In some embodiments, such as Figure 3 As shown, the fireproof isolation component 5 is disposed on the side of the piping installation cavity 19 near the first shell wall, and the end of the fireproof isolation component 5 away from the first shell wall abuts against the first end of the first refrigerant conveying pipe 41.

[0072] When the first shell wall is the bottom wall 110 of the shell 1, the fireproof isolation member 5 can be disposed on the lower side of the piping installation cavity 19, and the upper end of the fireproof isolation member 5 abuts against the first end of the first refrigerant delivery pipe 41. This arrangement creates a gap between the fireproof isolation member 5 and the cavity wall of the piping installation cavity 19 on the side away from the first shell wall (the upper cavity wall of the piping installation cavity 19), so as to partially isolate the piping installation cavity 19 and the fan installation cavity 17 through the fireproof isolation member 5, thereby reducing the smoke entering the fan installation cavity 17 and the fan assembly 2 when electronic components accidentally catch fire.

[0073] The fireproof isolation component 5 abuts against the first end of the first refrigerant conveying pipe 41, so that the fireproof isolation component 5 can also act as a pipe clamping plate for the first refrigerant conveying pipe 41, which enhances the supporting and limiting effect of the first refrigerant conveying pipe 41 and improves the fixing effect of the first refrigerant conveying pipe 41.

[0074] In some embodiments, such as Figure 3 As shown, the duct unit also includes a first water receiving tray 61 located inside the housing 1. The first water receiving tray 61 is located below the piping assembly 4 and is configured to receive condensate from the piping assembly 4.

[0075] When the first shell wall is the bottom wall 110 of the shell 1, the lower end of the fireproof isolation member 5 can be connected to the first water receiving tray 61, and the upper end can abut against the first end of the first refrigerant conveying pipe 41. The first water receiving tray 61 can be used to form the lower cavity wall of the piping installation cavity 19, that is, the lower end of the fireproof isolation member 5 can be connected to the lower cavity wall of the piping installation cavity 19.

[0076] In some embodiments, such as Figure 3 and Figure 4 As shown, the fireproof isolation component 5 includes a fireproof sponge 51, which is bonded and fixed to the first water receiving tray 61.

[0077] The fireproof sponge 51 is elastic, can be deformed elastically, and is lightweight. It can be easily bonded and fixed to the first water receiving tray 61. It can reduce the smoke entering the fan installation cavity 17 and fan assembly 2 when a fire occurs, while supporting and limiting the first refrigerant delivery pipe 41 by pressing the first end of the first refrigerant delivery pipe 41.

[0078] Of course, the fireproof isolation component 5 is not limited to the fireproof sponge 51, but can also be other isolation components with fireproof functions, such as fireproof partitions.

[0079] In other embodiments, such as Figures 5-10 As shown, one end of the fireproof isolation member 5 is close to the first shell wall, and the other end extends away from the first shell wall. The four edges of the fireproof isolation member 5 are all in contact with the cavity wall of the piping installation cavity 19 to separate the piping installation cavity 19 and the fan installation cavity 17.

[0080] When the first shell wall is the bottom wall 110 of the shell 1, the fireproof isolation member 5 can be installed vertically as a whole, and the lower end of the fireproof isolation member 5 can be close to the first shell wall, while the upper end extends away from the first shell wall. The vertically installed fireproof isolation member 5 can be perpendicular to the horizontal direction, or it can be tilted at a certain angle relative to the direction perpendicular to the horizontal direction.

[0081] The fireproof isolation component 5 has its four edges abutting against the cavity wall of the piping installation cavity 19 to completely isolate the connecting channel between the piping installation cavity 19 and the fan installation cavity 17. This can greatly reduce or even completely prevent smoke generated by fire from entering the fan installation cavity 17 and the fan assembly 2, so as to ensure that the smoke generation meets the regulatory requirements.

[0082] In other embodiments, such as Figures 5-10 As shown, the duct unit also includes a first drip tray 61 disposed within the housing 1. The first drip tray 61 is located below the piping assembly 4 and is configured to collect condensate from the piping assembly 4. The first drip tray 61 can form the lower cavity wall of the piping installation cavity 19. The fireproof isolation component 5 includes a vertically arranged first fireproof partition 52, the lower end of which abuts against the first drip tray 61.

[0083] In the fireproof isolation component 5, the lower end of the first fireproof partition 52 abuts against the first water receiving tray 61 that forms the lower cavity wall of the piping installation cavity 19, so as to achieve the abutment between the first fireproof partition 52 and the lower cavity wall of the piping installation cavity 19. This is beneficial to ensure that all four edges of the fireproof isolation component 5 abut against the cavity wall of the piping installation cavity 19, so as to greatly reduce or even completely isolate the smoke generated by the fire from entering the fan installation cavity 17 and the fan assembly 2.

[0084] In other embodiments, such as Figures 5-10 As shown, the piping assembly 4 includes a first refrigerant delivery pipe 41 and a second refrigerant delivery pipe 43. The first ends of both the first refrigerant delivery pipe 41 and the second refrigerant delivery pipe 43 extend toward the fan mounting cavity 17. The second ends of both the first refrigerant delivery pipe 41 and the second refrigerant delivery pipe 43 are connected to the indoor heat exchanger, so that both the first refrigerant delivery pipe 41 and the second refrigerant delivery pipe 43 are in communication with the indoor heat exchanger.

[0085] In other embodiments, such as Figure 5-Figure 8 As shown, the fireproof partition 5 also includes a vertically arranged second fireproof partition 53. The first fireproof partition 52 and the second fireproof partition 53 are arranged side by side and located on both sides of the first end of the first refrigerant conveying pipe 41 and the second refrigerant conveying pipe 43, respectively. The first fireproof partition 52 has two first notches 521 on its first side near the second fireproof partition 53 (see...). Figure 11 and Figure 12 The second fireproof partition 53 has two second notches on its second side near the first fireproof partition 52. The two first notches 521 cooperate with the two second notches to form two perforations. The first ends of the first refrigerant delivery pipe 41 and the second refrigerant delivery pipe 43 pass through the two perforations respectively.

[0086] The first fireproof partition 52 and the second fireproof partition 53 cooperate to form two through holes, allowing the first ends of the first refrigerant delivery pipe 41 and the second refrigerant delivery pipe 43 to pass through and extend into the fan mounting cavity 17. The first fireproof partition 52 and the second fireproof partition 53 can act as piping pressure plates for the first refrigerant delivery pipe 41 and the second refrigerant delivery pipe 43, enhancing their supporting and limiting effect and improving the fixing effect of the first refrigerant delivery pipe 41 and the second refrigerant delivery pipe 43.

[0087] In other embodiments, such as Figure 5-Figure 8 As shown, the second side of the second fireproof partition 53 abuts against the first side of the first fireproof partition 52, and the lower end of the second fireproof partition 53 is configured to abut against the first water receiving tray 61 or the first fireproof partition 52.

[0088] The second side of the second fireproof partition 53 abuts against the first side of the first fireproof partition 52 to minimize the amount of smoke generated during a fire from entering the fan mounting cavity 17 and the fan assembly 2 through the gap between the second fireproof partition 53 and the first fireproof partition 52; the lower end of the first fireproof partition 52 abuts against the first water receiving tray 61 forming the lower cavity wall of the piping mounting cavity 19, the lower end of the second fireproof partition 53 may abut against the first water receiving tray 61 or the first fireproof partition 52, and the upper ends of the first fireproof partition 52 and the second fireproof partition 53 may abut against the upper cavity wall of the piping mounting cavity 19. The third side of plate 52 away from the second fireproof partition 53 and the fourth side of the second fireproof partition 53 away from the first fireproof partition 52 respectively abut against the other two cavity walls of the piping installation cavity 19 on the side close to the fan installation cavity 17 (the other two cavity walls of the piping installation cavity 19 besides the upper cavity wall and the lower cavity wall, such as the left cavity wall and the right cavity wall of the piping installation cavity 19) to seal the piping installation cavity 19, thereby completely isolating the communication channel between the piping installation cavity 19 and the fan installation cavity 17, so as to greatly reduce the smoke generated by the fire from entering the fan installation cavity 17 and the fan assembly 2.

[0089] The first fireproof partition 52 and the second fireproof partition 53 in this embodiment not only seal the piping installation cavity 19 and completely isolate the piping installation cavity 19 from the fan installation cavity 17, but also serve as piping pressure plates.

[0090] In other embodiments, such as Figure 11 and Figure 12 As shown, the first water receiving tray 61 and the first fireproof partition 52 are an integral structure. For example, the first water receiving tray 61 and the first fireproof partition 52 can be a one-piece sheet metal structure. Of course, this integral structure is not limited to sheet metal structures and can also be achieved using other materials.

[0091] Setting the first water receiving tray 61 and the first fireproof partition 52 as an integrated structure helps to reduce the number of parts and simplify the structure and assembly process of the whole machine.

[0092] Of course, the first water receiving tray 61 and the first fireproof partition 52 can also be configured as separate structures as needed.

[0093] In other embodiments, the second fireproof partition 53 is located on the side of the first end of the first refrigerant delivery pipe 41 and the second refrigerant delivery pipe 43 near the air supply cavity 18, and the second fireproof partition 53 is fixed to the air supply cavity 18, or the second fireproof partition 53 and the cavity wall of the air supply cavity 18 are an integral structure.

[0094] The first fireproof partition 52 is located on the side away from the air supply cavity 18 at the first end of the first refrigerant supply pipe 41 and the second refrigerant supply pipe 43, and the second fireproof partition 53 is located on the side near the air supply cavity 18 at the first end of the first refrigerant supply pipe 41 and the second refrigerant supply pipe 43. The second fireproof partition 53 can be fixed to the air supply cavity 18, or the second fireproof partition 53 and the cavity wall of the air supply cavity 18 are an integral structure. Setting the second fireproof partition 53 and the cavity wall of the air supply cavity 18 as an integral structure helps to reduce the number of parts and simplify the structure and assembly process of the whole machine.

[0095] In some exemplary embodiments, such as Figure 5 , Figures 7-10 As shown, the ducted air conditioner also includes an indoor heat exchanger and a second water collection tray 62. The indoor heat exchanger can be installed in the air supply cavity 18 and connected to the piping assembly 4, such as the first refrigerant supply pipe 41 or the second refrigerant supply pipe 43 of the piping assembly 4. The second water collection tray 62 is installed below the indoor heat exchanger and is configured to collect the condensate on the indoor heat exchanger.

[0096] The first water receiving tray 61 and the second water receiving tray 62 are separate structures, and one end of the first water receiving tray 61 is attached to the second water receiving tray 62 so that the condensate in the first water receiving tray 61 can flow to the second water receiving tray 62.

[0097] The first drip tray 61 and the second drip tray 62 are configured as separate structures, with one end of the first drip tray 61 overlapping the second drip tray 62. The first drip tray 61 can be tilted, and the height of the end of the first drip tray 61 overlapping the second drip tray 62 can be lower than the height of the end of the first drip tray 61 furthest from the second drip tray 62, so that the condensate in the first drip tray 61 can flow into the second drip tray 62 under the action of gravity. The outer surface of the first drip tray 61 can be insulated with materials such as sponge to prevent condensation from forming on its outer surface.

[0098] The first water receiving tray 61 and the second water receiving tray 62 are separate structures. Compared with setting the first water receiving tray 61 and the second water receiving tray 62 as an integrated structure, the separate structure makes it easier to disassemble the first water receiving tray 61 or the second water receiving tray 62 separately, which facilitates the maintenance of the whole machine.

[0099] exist Figures 5-12 In other embodiments shown, the first water receiving tray 61 and the second water receiving tray 62 are configured as separate structures, and the first water receiving tray 61 and the first fireproof partition 52 are configured as an integrated structure.

The air outlet of the fan assembly 2 is connected to the air inlet side of the air supply cavity 18, and the air outlet side of the air supply cavity 18 can be connected to the air supply outlet 16.

[0103] In some exemplary embodiments, such as Figure 5 , Figures 9-10 As shown, the fan assembly 2 may include a motor 21 and a fan wheel 22. The motor 21 may be connected to the fan wheel 22 and drive the fan wheel 22 to rotate. There may be two fan wheels 22, which may be located on both sides of the motor 21 and connected to the motor 21, so that the motor 21 can drive both fan wheels 22 to rotate at the same time, thereby increasing the air volume of the duct fan.

[0104] In some exemplary embodiments, such as Figures 9-10 As shown, the housing 1 is provided with a first partition wall 112 and a second partition wall 113.

[0105] The first partition wall 112 can separate the air supply cavity 18 and the fan mounting cavity 17, and the first partition wall 112 can be a common wall for the air supply cavity 18 and the fan mounting cavity 17. A connecting hole can be opened on the common wall to connect the air supply cavity 18 and the fan mounting cavity 17.

[0106] The second partition wall 113 can separate the air supply cavity 18 and the piping installation cavity 19, and the second partition wall 113 can be a common wall for the air supply cavity 18 and the piping installation cavity 19.

[0107] like Figures 9-10As shown, the piping installation cavity 19 can be located on the left side of the air supply cavity 18. The front wall 11 of the housing 1 can form the front cavity wall of the piping installation cavity 19, the top wall 111 of the housing 1 can form the upper cavity wall of the piping installation cavity 19, the first water receiving tray 61 can form the lower cavity wall of the piping installation cavity 19, the left wall 13 of the housing 1 can form the left cavity wall of the piping installation cavity 19, the second partition wall 113 can form the right cavity wall of the piping installation cavity 19, and the rear opening of the piping installation cavity 19 is connected to the fan installation cavity 17.

[0108] Figures 5-12 In other embodiments shown, the top wall 111 and side walls of the housing 1, the first water receiving tray 61, the first fireproof partition 52, the second fireproof partition 53, and the second partition wall 113 cooperate to form a fireproof sealing structure that prevents smoke from entering the fan mounting cavity 17 and the fan assembly 2 after a fire. The second fireproof partition 53 can be integrated with either the first partition wall 112 or the second partition wall 113.

[0109] This application also provides an air conditioner, including the ducted air conditioner of any of the above embodiments.

[0110] The air conditioner may also include an outdoor unit, which can be connected to and work in conjunction with a ducted air conditioner.

[0111] In summary, the embodiments of this application provide a fire-resistant, sealable, bottom-return duct air conditioner. By setting fire-resistant sponge 51, or by setting a first fire-resistant partition 52, a second fire-resistant partition 53, the top wall 111 and side walls of the housing 1, a first water tray 61 and a second partition wall 113 to form a fire-resistant sealing structure, the shock-absorbing components (such as shock-absorbing rubber 42) and electronic components (such as control valves) that do not have fire-resistant properties meet UL fire-resistant requirements. By integrally molding the first fire-resistant partition 52 with the first water tray 61, and setting the first water tray 61 and the second water tray 62 as separate structures, the convenience of overall machine maintenance is improved through the separation and combination of components.
