[0066] The living room and dining room are integrated in the house, and the space depth is relatively large. When the air conditioner is installed on one side of the room, the cooling and heating effect on the other side is poor. The indoor unit of the duct air conditioner can be installed in the middle of the deep space, such as in the ceiling separating the living room and dining room, but the air can only be discharged in one direction, and the cooling and heating needs in the other direction cannot be taken into account. If two duct units with different air outlet directions are installed, the cost of use will be greatly increased. In order to meet the cooling and heating needs of users for large-depth spaces at a low cost, the related art discloses an indoor unit of a duct machine, including: a shell, a first indoor heat exchanger, a second indoor heat exchanger and a fan assembly, wherein a first air duct and a second air duct separated from each other are arranged in the shell, the first air duct has a first air inlet and a first air outlet, and the second air duct has a second air inlet and a second air outlet; the first indoor heat exchanger is arranged in the first air duct; the second indoor heat exchanger is arranged in the second air duct; the first fan assembly includes a first wind wheel and a second wind wheel, the first wind wheel is arranged in the first air duct to drive the airflow from the first air inlet to the first air outlet, and the second wind wheel is arranged in the second air duct to drive the airflow from the second air inlet to the second air outlet. The problem with the related art is that the air outlet mode of the first fan assembly and the second fan assembly has been determined at the time of leaving the factory, and it is difficult to adjust according to the actual situation.

[0067] In order to make the indoor unit of the duct air conditioner flexibly adjust the one-way air outlet mode and the two-way air outlet mode, combined with Figures 1 to 20 As shown, the embodiment of the present disclosure provides a duct-type air-conditioning indoor unit, which includes a shell 100, a heat exchanger 200 and a plurality of fan assemblies, wherein the shell 100 is configured with an accommodating space, a first side wall 140 of the shell 100 is provided with an air inlet and outlet 141, and a second side wall 150 or a bottom is provided with a first return air inlet 151 and a first air outlet 152; the heat exchanger is arranged in the accommodating space along the length direction of the shell 100; a plurality of fan assemblies are arranged in the accommodating space corresponding to the heat exchanger, and when the fan assemblies are assembled in a first manner, the air outlet direction is toward the air inlet and outlet 141, and the return air direction is toward the first return air inlet 151, and when they are assembled in a second manner, the air outlet direction is toward the first air outlet 152, and the return air direction is toward the air inlet and outlet 141.

[0068] The indoor unit of the duct air conditioner is also called a duct unit. In most cases, the indoor unit of the duct air conditioner is a one-to-one unit, that is, one outdoor unit is connected to one indoor unit through a copper pipe. The indoor unit of the duct air conditioner blows cold or hot air to the indoor environment.

[0069] The duct type air conditioner indoor unit provided in the embodiment of the present disclosure includes a housing 100 , which defines an accommodation space and forms an air duct in the accommodation space.

[0070] Specifically, the first side wall 140 of the ducted air conditioner is provided with an air inlet and outlet 141. The air inlet and outlet 141 is a general term. In some cases, the air inlet and outlet 141 is a window, and a part of it is used as an air outlet, and the other part is used as a return air outlet. In other cases, the air inlet and outlet 141 is two windows, one of which is used as a return air outlet, and the other is used as an air outlet.

[0071] The second side wall 150 or the bottom of the duct unit is provided with a first return air port 151 and a first air outlet 152. The second side wall 150 is a side wall opposite to the first side wall 140. In the duct type air conditioner provided in the embodiment of the present disclosure, the front panel facing the user in the use state is used as the first side wall 140, and the back panel away from the user is used as the second side wall 150.

[0072] When the first air return port 151 and the first air outlet 152 of the duct air conditioner are opened on the second side wall 150, the duct air conditioner indoor unit can realize rear air intake and front air outlet and front air intake and rear air outlet at the same time.

[0073] When the first air return port 151 and the first air outlet 152 of the duct air conditioner are opened at the bottom, the duct air conditioner indoor unit can simultaneously realize bottom air intake and front air outlet and front air intake and bottom air outlet.

[0074] The heat exchanger is arranged in the accommodation space along the length direction of the housing 100. When the duct type air conditioner indoor unit is in use, when the user faces the front panel of the duct type air conditioner indoor unit, the left and right direction is the length direction, the front and back direction is the depth direction, and the up and down direction is the top and bottom direction. One side of the heat exchanger corresponds to the air inlet and outlet 141 of the housing 100, and the other side corresponds to the first return air port 151 and the first air outlet 152. When the duct type air conditioner indoor unit is working, a part of the heat exchanger is located in the first air duct formed between the air inlet and outlet 141 and the first return air port 151, and the other part of the heat exchanger is located in the second air duct formed between the air inlet and outlet 141 and the first air outlet 152.

[0075] The duct type air conditioner indoor unit includes an air outlet assembly 300, and the air outlet assembly 300 includes a plurality of fan assemblies. The fan assembly has a first installation mode and a second installation mode. When the fan assembly is installed in the first installation mode, the air outlet direction is toward the air inlet and outlet, and the return air direction is toward the first return air vent 151; when the fan assembly is installed in the second installation mode, the air outlet direction is toward the first air outlet 152, and the air inlet direction is toward the air inlet and outlet 141.

[0076] Exemplarily, the duct air conditioner includes four fan assemblies indoors, and all four fan assemblies are installed in accordance with the first installation method. At this time, the duct air conditioner indoor unit has air outlet from the front side and air return from the rear side. All four fan assemblies are installed in accordance with the second installation method. At this time, the duct air conditioner indoor unit has air outlet from the rear side and air return from the front side. Two of the four fan assemblies are installed in accordance with the first method and the other two are installed in accordance with the second method. At this time, the duct air conditioner indoor unit can simultaneously discharge air from the front side and the rear side, and the air volume on the front and rear sides is equal. One of the four fan assemblies is installed in accordance with the first installation method and the other three are installed in accordance with the second installation method. At this time, the duct air conditioner indoor unit can simultaneously discharge air from the front side and the rear side, and the air volume of the front side air outlet is less than the air volume of the rear side air outlet. Three of the four fan assemblies are installed in accordance with the first installation method and the other one is installed in accordance with the second installation method. At this time, the duct air conditioner indoor unit can simultaneously discharge air from the front side and the rear side, and the air volume of the front side air outlet is greater than the air volume of the rear side air outlet.

[0077] Using the duct type air-conditioning indoor unit provided by the embodiment of the present disclosure, the fan assembly has two installation methods in different directions, and can realize air outlet methods with different air volumes and directions according to actual usage requirements. One model can meet most one-way and two-way air outlet requirements through flexible fan assembly installation methods.

[0078] Optionally, combined Figures 17 to 20 As shown, the fan assembly includes a volute 700 and a first mounting plate 710, wherein air inlets are provided on both sides of the volute 700 and air outlets are provided on the side; the first mounting plate 710 has an installation window, the volute 700 is snap-connected to the first mounting plate 710, and the air outlet corresponds to the installation window.

[0079] The fan assembly is a cross-flow fan, and includes a volute 700, with air inlets at both ends and air outlets at the side walls. The fan assembly also includes a mounting plate, which is fixed to the volute 700 through a mounting window. The mounting plate can be installed at different positions of the housing space, so that the fan assembly can be installed in a first installation mode and a second installation mode.

[0080] Specifically, when the fan assembly is installed in the first installation mode, the mounting plate is close to the heat exchanger, and the volute 700 is located between the mounting plate and the rear side wall of the housing 100. When the fan assembly is installed in the second installation mode, the mounting plate is close to the rear side wall of the housing 100 or serves as a part of the rear side wall of the housing 100, and the volute 700 is located between the mounting plate and the heat exchanger.

[0081] Such a configuration is helpful for realizing different installation modes of the fan assembly.

[0082] Optionally, multiple first mounting plates 710 of fan assemblies installed in the first mounting manner are spliced ​​together to form a middle partition 130, and the middle partition 130 divides the accommodating space into a refrigeration space and a temperature-changing space. The heat exchanger is located in the refrigeration space, and multiple fan assemblies are located in the temperature-changing space.

[0083] When multiple fan assemblies are installed in the first manner, the volute 700 is located between the rear side plate and the evaporator. Multiple middle partitions 130 of multiple fan assemblies installed in the first manner are spliced ​​together to form the middle partition 130 or serve as a part of the middle partition 130. The evaporator is located on one side of the middle partition 130, and the fan assembly is located on the other side of the middle partition 130. With such a setting form, on the one hand, the first mounting plate 710 of the fan assembly as the middle partition 130 can reduce the cost of the indoor unit of the duct-type air conditioner, and on the other hand, the first mounting plate 710 as the middle partition 130 can improve the fixing effect of the volute 700.

[0084] Optionally, the duct-type air conditioner indoor unit further includes a second mounting plate 720, which is connected to the first mounting plate 710 and faces the return air outlet on the side of the volute 700. The second mounting plate 720 separates two adjacent fan assemblies with different air outlet directions.

[0085] For example, the plurality of fan assemblies of the indoor unit of the duct type air conditioner are divided into two groups, and the air outlet directions of the two groups of fan assemblies are different. The second mounting plate 720 is connected to the first mounting plate 710 and divides the two adjacent groups of fan assemblies. With such a setting form, the return air short circuit between the two groups of fan assemblies can be reduced or avoided.

[0086] Optionally, the duct type air conditioner indoor unit further includes a driving motor 610, which is disposed in the accommodating space and is used to drive the plurality of fan components to rotate.

[0087] The driving motor 610 drives multiple fan assemblies to rotate simultaneously, which can reduce the number of driving motors 610, reduce the weight of the duct-type air-conditioning indoor unit, and reduce the cost of the duct-type air-conditioning indoor unit.

[0088] Optionally, the driving motor 610 is fixed to a first mounting plate 710 of a fan assembly among the plurality of fan assemblies.

[0089] The drive motor 610 is fixed to the first mounting plate 710 of the fan assembly, which is less likely to cause vibration of the housing 100 than the drive motor 610 is fixed to the top plate 110 or the bottom plate 120 of the housing 100. This can reduce the operating noise of the indoor unit of the duct type air conditioner.

[0090] Optionally, the first mounting plate 710 is configured with a bending portion 711 , and the bending portion 711 is suitable for being crimped onto the inner wall of the housing 100 , and the fan assembly is fixed to the housing 100 via the first mounting plate 710 .

[0091] The first mounting plate 710 is pressed against the inner wall of the housing 100 , which can further improve the fixing effect of the duct type air conditioner indoor unit on the fan assembly.

[0092] Optionally, the bending portion 711 includes a first bending portion 711 and a second bending portion 711, the first bending portion 711 is located at the top of the first mounting plate 710 and is pressed against the top wall of the housing 100, and the second bending portion 711 is located at the bottom of the first mounting plate 710 and is pressed against the bottom of the housing 100. This is conducive to fixing the fan assembly of the duct type air conditioner indoor unit.

[0093] Optionally, the shell 100 includes a top plate 110 and a bottom plate 120 , wherein the top plate 110 is configured with a first avoidance groove 111 , and the top of the fan assembly is accommodated in the first avoidance groove 111 ; the bottom plate 120 is configured with a second avoidance groove 121 , and the bottom of the fan assembly is accommodated in the second avoidance groove 121 .

[0094] The top plate 110 of the housing 100 is configured with a first avoidance groove 111 and the bottom plate 120 is configured with a second avoidance groove 121, which can reduce the thickness of the duct type air conditioner indoor unit and is conducive to the miniaturization of the duct type air conditioner indoor unit.

[0095] Optionally, there is a gap between the top of the fan assembly and the bottom of the first avoidance groove 111 ; and / or there is a gap between the bottom of the fan assembly and the bottom of the second avoidance groove 121 .

[0096] This can reduce the vibration of the housing 100 caused by the contact between the volute 700 and the housing 100 of the duct type air conditioner indoor unit when the fan assembly is running, which is beneficial to reducing the operating noise of the duct type air conditioner indoor unit.

[0097] Optionally, the first avoidance groove 111 corresponds to the tops of a plurality of fan assemblies; the bottom plate 120 is configured with a plurality of second avoidance grooves 121, and the plurality of second avoidance grooves 121 are adapted to the plurality of fan assemblies.

[0098] The first avoidance grooves 111 correspond to the tops of the plurality of fan components, which is beneficial to the stamping process of the top plate 110 of the housing 100. The bottom plate 120 is configured with a plurality of second avoidance grooves 121, which can improve the structural strength of the bottom, thereby improving the overall structural strength of the duct type air conditioner indoor unit.

[0099] Optionally, the duct type air conditioner indoor unit includes a heat exchanger partition 210, which is arranged in the accommodation space and located between the evaporator and the air inlet and outlet 141. The heat exchanger partition 210 includes a partition 211 and a shielding portion 214. The heat exchanger partition 210 includes a shielding portion 214, and the shielding portion 214 and the partition 211 form a temperature change area with less air flow. The temperature change area can make the temperature difference between the air-conditioning outlet air and the air-conditioning return air distributed in an area along the length direction of the shell 100, thereby reducing the temperature difference on both sides of the heat exchanger partition 210 itself. In this way, condensation on one or both sides of the heat exchanger partition 210 can be reduced or avoided. In addition, the heat exchanger partition 210 includes a shielding portion 214 extending along the length direction of the shell 100, which can better separate the air entering the accommodation space through the air inlet and outlet 141 and the air blown out through the air inlet and outlet 141, thereby reducing or avoiding the return air short circuit outside the shell 100.

[0100] When using the duct-type air-conditioning indoor unit provided by the embodiment of the present disclosure, the shielding portion 214 and the dividing portion 211 of the heat exchanger partition 210 form a temperature change area with less air flow, thereby reducing the temperature difference on both sides of the heat exchanger partition 210 itself, thereby reducing or avoiding condensation on one or both sides of the heat exchanger partition 210; the heat exchanger partition 210 includes a shielding portion 214, which extends along the length direction of the shell 100, so that the first air duct and the second air duct can be better separated, thereby reducing or avoiding the return air short circuit outside the shell 100.

[0101] Optionally, combined Figure 5 As shown, the heat exchanger partition 210 further includes a first abutting portion 212 . The first abutting portion 212 extends from the rear end of the partition portion 211 along the length direction of the shell 100 . The first abutting portion 212 abuts against the heat exchanger.

[0102] The extension direction of the first abutting portion 212 is the same as the length direction of the evaporator, that is, along the length direction of the housing 100. The first abutting portion 212 abuts against the heat exchanger, which can enhance the separation effect of the heat exchanger partition 210 on the one hand, and reduce or avoid scratching the fins or refrigerant pipes of the evaporator when assembling the heat exchanger partition 210 on the other hand.

[0103] Optionally, the first abutting portion 212 and the partition portion 211 are an integral structure.

[0104] This can improve the structural strength of the heat exchanger partition 210.

[0105] Optionally, the first abutting portion 212 and the partition portion 211 of the heat exchanger partition 210 are formed by injection molding.

[0106] The heat exchanger partition 210 is made of plastic, which can not only reduce the cost of the heat exchanger partition 210 but also enhance the heat insulation effect of the heat exchanger partition 210 , thereby reducing condensation on the heat exchanger partition 210 .

[0107] Optionally, the heat exchanger partition 210 and the first abutting portion 212 are formed by bending sheet metal.

[0108] In this way, the heat exchanger partition 210 can have a higher structural strength.

[0109] Optionally, the heat exchanger partition 210 further includes a second abutting portion 213 , which extends from a top end of the partition portion 211 along a length direction of the shell 100 , and the second abutting portion 213 abuts against the top plate 110 of the shell 100 .

[0110] The second abutting portion 213 abuts against the top plate 110 of the housing 100, which is beneficial to fix the heat exchanger partition 210. When the duct type air conditioner indoor unit is in operation, the heat exchanger partition 210 is not easy to deform or vibrate.

[0111] Optionally, the second abutting portion 213 and the partition portion 211 are an integral structure.

[0112] This can improve the structural strength of the heat exchanger partition 210.

[0113] Optionally, the first abutting portion 212 and the second abutting portion 213 are located on the same side of the partition portion 211 .

[0114] The first abutment portion 212 and the second abutment portion 213 are located on the same side of the partition portion 211 . The first abutment portion 212 , the second abutment portion 213 and the partition portion 211 can enclose a temperature variable area, thereby reducing the temperature difference between the left and right sides of the heat exchanger partition 210 , and further reducing condensation of the heat exchanger partition 210 .

[0115] Optionally, a heat insulating material is attached to at least one side of the partition 211 , or the partition 211 is a hollow structure filled with a heat insulating material.

[0116] The partition 211 is attached with heat insulation material, or the hollow partition is filled with heat insulation material, which can reduce the heat transfer of the heat exchanger partition 210 to the air conditioning outlet and air conditioning return air. This can further reduce or avoid condensation on both sides of the heat exchanger partition 210.

[0117] Optionally, the heat exchanger partition 210 is slidably disposed in the accommodating space, and the ratio of the first area to the second area is adjusted by sliding the heat exchanger partition 210 .

[0118] Combination Figure 6 , Figure 7As shown, the heat exchanger partition 210 is slidably disposed in the accommodating space and is located between the front panel and the heat exchanger. The heat exchanger partition 210 is a functional component that divides the first air duct and the second air duct and is in a slidable form. The heat exchanger partition 210 is vertically arranged, and the rear end is linearly connected to the evaporator, and the forward end extends at least to the air inlet and outlet 141. In this way, the heat exchanger partition 210 divides the area between the heat exchanger and the front panel into a first area and a second area. The first area corresponds to the first air duct, or the first area is a part of the first air duct. The second area corresponds to the second air duct, or the second area is a part of the second air duct.

[0119] The heat exchanger partition 210 is slidable. By moving the heat exchanger partition 210, the ratio of the first area to the second area, that is, the ratio of the size of the first area in the length direction of the shell 100 to the size of the second area in the length direction of the shell 100 can be adjusted.

[0120] Taking the first area as an example, after the heat exchanger partition 210 moves toward the direction of the second area, the size of the first area in the length direction of the shell 100 increases. In this way, the heat exchange area of ​​the heat exchanger corresponding to the first area can be increased, that is, the heat exchange area of ​​the heat exchanger in the first air duct is increased. The larger the heat exchange area of ​​the first air duct, the greater the cooling capacity of the duct-type air-conditioning indoor unit in the first air outlet direction defined by the first air duct. At this time, the heat exchange area of ​​the second air duct is reduced, and the cooling capacity of the duct-type air-conditioning indoor unit in the second air outlet direction defined by the second air duct is reduced. In this way, by moving the heat exchanger partition 210, the cooling and heating ratio of the first air outlet direction and the second air outlet direction can be adjusted, so that the duct-type air-conditioning indoor unit can more evenly meet the cooling and heating needs in different directions.

[0121] By using the duct type air conditioner indoor unit provided by the embodiment of the present disclosure, the partition ratio of the heat exchanger can be adjusted by moving the heat exchanger partition 210, thereby adjusting the cooling and heating ratio of the duct type air conditioner indoor unit in the first air outlet direction and the second air outlet direction. The duct type air conditioner indoor unit provided by the embodiment of the present disclosure can make the duct type air conditioner indoor unit have a higher cooling and heating efficiency when the air is discharged in only a single direction or in two directions, thereby better meeting the cooling and heating needs in different directions.

[0122] It should be noted that multiple fans are continuously distributed between the heat exchanger and the back plate of the housing 100. In order to make the direction of the air flow driven by the fan match the position of the heat exchanger partition 210, as an embodiment, the fan is a bidirectional fan. After moving the heat exchanger partition 210, the direction of the air flow driven by the fan is switched to match the position of the heat exchanger partition 210.

[0123] As another embodiment, the fan is a fixed cross-flow fan, and the air inlet and outlet directions of the fan cannot be changed. The return air port of the first fan 310 among the multiple fans corresponds to the first return air port 151 of the housing 100, and the air outlet faces the evaporator.

[0124] The return air outlet of the second fan 320 among the multiple fans is directed toward the evaporator, and the air outlet corresponds to the first air outlet 152 of the housing 100 .

[0125] After the position of the heat exchanger partition 210 changes, a portion of the air blown to the evaporator by the first fan 310 corresponds to the second area after passing through the evaporator. Since the air is throttled and decelerated, the initial velocity of this part of the air is low. After mixing with the normal temperature air entering the second area from the air inlet and outlet 141 driven by the second fan 320, it flows through the heat exchanger again and is blown out from the first air outlet 152 of the back panel. In this process, a return air short circuit occurs in the second area of ​​the front panel. Generally speaking, it is believed that the return air short circuit is harmful and will affect the air circulation volume between the indoor air and the indoor unit of the duct-type air conditioner. Therefore, the return air short circuit is to be avoided when designing and installing the indoor unit of the duct-type air conditioner. However, for the indoor unit of the duct-type air conditioner provided in the embodiment of the present disclosure, due to the function of two-way air outlet, the return air short circuit occurring in the second area actually causes a portion of the air to flow through the heat exchanger twice, and the air temperature blown out through the first air outlet 152 is lower under the same conditions. In addition, the return air short circuit only occurs in the second area, and the air not only flows back and forth or multiple times through the evaporator, but this return air short circuit is controllable and is helpful for the cooling and heating of the indoor unit of the duct type air conditioner.

[0126] Optionally, combined Figure 4 , Figure 5 As shown, the heat exchanger partition 210 further includes a driving portion 215 , and the driving portion 215 is connected to the partition portion 211 .

[0127] The partition 211 of the heat exchanger partition 210 serves to divide the first area and the second area. The driving unit 215 is connected to the partition 211, which is conducive to the duct type air conditioner indoor unit automatically or the user manually adjusting the position of the heat exchanger partition 210, thereby adjusting the cooling and heating ratio of the duct type air conditioner indoor unit in two directions.

[0128] Optionally, the driving portion 215 extends outward beyond the air inlet and outlet 141 .

[0129] This can further facilitate the user to manually adjust the position of the heat exchanger partition 210.

[0130] Optionally, the heat exchanger partition 210 further includes a driving device, which is drivingly connected to the driving portion 215 , and is used to drive the partition portion 211 to slide along the length direction of the shell 100 .

[0131] The drive device is provided, and the indoor unit of the duct type air conditioner has a hardware foundation for automatically adjusting the position of the heat exchanger partition 210, which is conducive to the automation and intelligence of the indoor unit of the duct type air conditioner.

[0132] Optionally, the driving device includes a gear, a rack and a position adjustment motor, the position adjustment motor is fixed in the accommodation space, and the driving shaft is connected to the gear; the rack is slidably arranged in the driving space and connected to the driving part 215 of the heat exchanger partition 210, and the gear and the rack are meshed. When the position adjustment motor rotates, the gear drives the rack to move, thereby driving the heat exchanger partition 210 to move along the length direction of the shell 100. With such a setting form, the structure of the driving device is simple and easy to maintain.

[0133] Optionally, the duct-type air conditioner indoor unit also includes an air guide plate assembly, which includes an air outlet frame, an air duct and an air guide plate. The air duct is used to connect the air inlet and outlet and the air outlet frame. The air guide plate is arranged on the air outlet frame, and the driving part of the heat exchanger partition extends to the air outlet frame.

[0134] After the indoor unit of the duct type air conditioner is installed on the ceiling, the air outlet frame is exposed and accessible. The driving part of the heat exchanger partition extends to the air outlet frame, which can facilitate the user to adjust the position of the heat exchanger partition.

[0135] Optionally, the air guide plate assembly also includes an air guide baffle, which is connected to the driving unit or has the same structure as the driving unit. The air guide plate separates the air outlet frame into a first air outlet unit and a second air outlet unit. The first air outlet unit corresponds to the first air duct, and the second air outlet unit corresponds to the second air duct.

[0136] By adopting such an arrangement, the return air short circuit at the air guide plate assembly can be reduced or avoided.

[0137] Optionally, the duct-type air conditioner indoor unit further includes a driving device, which is disposed on the air guide plate assembly and is used to drive the air guide baffle and the driving unit to move.

[0138] Such a setting is helpful to adjust the position of the heat exchanger partition.

[0139] Optionally, the heat exchanger partition 210 further includes a sliding portion, the sliding portion is connected to the driving portion 215 or the partition portion 211 , and the sliding portion is slidably connected to the shell 100 .

[0140] The heat exchanger partition 210 further includes a sliding portion, and the heat exchanger partition 210 can move more smoothly when the heat exchanger partition 210 is moved manually or electrically.

[0141] Optionally, the sliding part includes a pulley, the housing 100 is configured with a slide groove, and the pulley of the heat exchanger partition 210 is located in the slide groove.

[0142] This can further reduce the sliding resistance of the heat exchanger partition 210.

[0143] Optionally, the sliding part includes a first slide and a second pulley, the top wall of the shell 100 is configured with a first slide groove, the bottom of the shell 100 is configured with a second slide groove, the first pulley is located in the first slide groove, and the second pulley is located in the second slide groove.

[0144] The first slide groove and the second slide groove not only define a sliding track for the first pulley and the second pulley of the sliding part, but also define a sliding path for the sliding of the heat exchanger partition 210, thereby achieving sliding fixation of the heat exchanger partition 210. With such a setting, the sliding of the heat exchanger partition 210 is relatively smooth, and the sliding path is clear.

[0145] Optionally, combined Figure 8 As shown, the duct type air conditioner indoor unit also includes a duct partition 220, which is arranged on the other side of the heat exchanger. The duct partition 220 divides the space between the heat exchanger and the air outlet assembly 300 into a first duct and a second duct. A part of the multiple fans corresponds to the first duct, and the other part corresponds to the second duct.

[0146] The air outlet assembly 300 of the duct type air conditioner indoor unit includes a plurality of fans, which are divided into two groups, and the air outlet directions of the two groups of fans are different. Specifically, the air duct partition 220 extends along the depth direction of the housing 100, and separates the space between the heat exchanger and the air outlet assembly 300 into a first air duct and a second air duct, one group of fans is located in the first air duct, and the other group of fans is located in the second air duct. With such a setting form, the return air short circuit at the air outlet assembly 300 can be reduced or avoided.

[0147] Optionally, the air outlet assembly 300 includes a first fan 310 and a second fan 320, wherein the first fan 310 has an air outlet direction toward the heat exchanger; and the second fan 320 has a return air direction toward the heat exchanger; wherein the number of the first fan 310 or the second fan 320 is multiple.

[0148] The air outlet assembly 300 includes a plurality of first fans 310 or a plurality of second fans 320, which can increase the air outlet volume of the duct-type air conditioner indoor unit in the first air outlet direction or the second air outlet direction, thereby improving the overall cooling and heating effect of the duct-type air conditioner indoor unit.

[0149] Optionally, the number of the first fans 310 is the same as the number of the second fans 320 .

[0150] When the number of the first fan 310 and the second fan 320 is the same, they can be evenly distributed on both sides or different positions of the indoor unit, thereby ensuring a more balanced circulation of air in the indoor space. This balanced air circulation helps to achieve a uniform distribution of indoor temperature and improve comfort. The same number of fans means that power can be more evenly distributed to each fan, avoiding excess or insufficient power in certain areas. This helps to reduce energy consumption and improve overall energy efficiency. When the number of fans is the same, the load distribution of the system is more even, reducing the risk of failure due to uneven load and improving the stability and reliability of the system.

[0151] Optionally, the first fan 310 and the second fan 320 rotate coaxially.

[0152] The first fan 310 and the second fan 320 rotate coaxially, which is beneficial to the assembly of the first fan 310 and the second fan 320 .

[0153] Optionally, the duct-type air-conditioning indoor unit further includes a dual-shaft motor, which is disposed in the accommodating space, and both ends of the output shaft of the dual-shaft motor are drivingly connected to the first fan 310 and the second fan 320 .

[0154] The duct type air conditioner indoor unit provided by the embodiment of the present disclosure can adjust the ratio of the evaporator corresponding to the first air duct and the second air duct by moving the heat exchanger partition 210, and allow the return air short circuit to occur between the evaporator and the front panel of the housing 100. Therefore, the cooling and heating ratio of the duct type air conditioner indoor unit in different directions can still be adjusted when all the fans rotate synchronously. Therefore, multiple fans are driven by one motor, which not only does not cause difficulty in controlling cooling and heating, but also can reduce the number of driving motors 610, reduce the weight of the duct type air conditioner indoor unit, and thus reduce the cost of the duct type air conditioner indoor unit.

[0155] One of the characteristics of a dual-shaft motor is smooth torque and stable operation. This allows it to provide more uniform and stable power when driving the fan, helping to reduce mechanical vibration and noise. By using one dual-shaft motor to drive multiple fans at the same time, the structure of the entire system can be significantly simplified. This not only reduces the number of required components, but also reduces the complexity of manufacturing and assembly, thereby helping to reduce production costs. The compact design of the dual-shaft motor can improve space utilization. Due to the simplified system structure, the indoor unit of the ducted air conditioner driven by the dual-shaft motor is also simpler in maintenance and repair. This helps to reduce downtime and maintenance costs and improve the overall availability of the equipment.

[0156] Optionally, the duct type air conditioner indoor unit includes a plurality of first fans 310 and a plurality of second fans 320 , the plurality of first fans 310 share a first rotating shaft, and the plurality of second fans 320 share a second rotating shaft.

[0157] By increasing the number of the first fan 310 and the second fan 320, the circulation efficiency of the indoor air can be significantly improved. When multiple fans work at the same time, the cold air or hot air can be blown to every corner of the room more quickly and evenly, thereby improving the temperature uniformity of the entire space. The design of multiple fans sharing a rotating shaft makes the structure of the entire system more compact and optimizes space utilization. Multiple fans share the same rotating shaft, and the control system can be simplified. At the same time, during maintenance, only a few rotating shafts need to be inspected and maintained, reducing the complexity and cost of maintenance.

[0158] Optionally, combined Figures 9 to 11 As shown, the duct type air conditioner indoor unit also includes a first connector 620 and a second connector 630, wherein one end of the first connector 620 is connected to the first end of the first rotating shaft, and the other end is connected to an output shaft of the drive motor 610; one end of the second connector 630 is connected to the first end of the second rotating shaft, and the other end is connected to another output shaft of the drive motor 610.

[0159] The first connector 620 and the second connector 630 serve as a bridge between the drive motor 610 and the rotating shaft, ensuring the stability and efficiency of power transmission. The connection between the rotating shaft and the output shaft is achieved through the connector, which simplifies the installation process. When maintenance or replacement of parts is required, only the connector needs to be removed, and there is no need to disassemble the entire system on a large scale, thereby reducing maintenance costs and time. The design of the connector allows the connection between the rotating shaft and the output shaft to have certain flexibility and adjustability. The first connector 620 and the second connector 630 can reduce failures caused by poor connection or looseness. At the same time, they can also withstand certain vibrations and shocks, improving the reliability and stability of the entire system.

[0160] Optionally, the duct type air conditioner indoor unit further comprises a first bearing bracket and a second bearing bracket, wherein the first bearing bracket is used for rotatably setting the second end of the first rotating shaft; and the second bearing bracket is used for rotatably setting the second end of the second rotating shaft.

[0161] The bearing bracket provides stable support for the rotating shaft, ensuring that the rotating shaft remains stable at high speeds and reducing vibration and shaking. This helps improve the operating efficiency of the fan, reduce noise, and extend the service life of the rotating shaft. The bearing is installed inside the bearing bracket. The presence of the bearing can reduce the direct contact between the rotating shaft and the bracket, thereby reducing friction and wear. This not only helps to keep the rotating shaft running smoothly, but also reduces energy loss and improves the energy efficiency of the entire system.

[0162] Optionally, the first connector 620 includes a first cylinder 621 , a side wall of which is provided with a first bolt hole 622 and a second bolt hole 623 , wherein the first bolt hole 622 is suitable for fixing the first rotating shaft, and the second bolt hole 623 is suitable for fixing an output shaft of the driving motor 610 .

[0163] By adopting a cylindrical structure as the first connector 620, not only is the structure simple, but the assembly process also becomes relatively simple. This design makes the connection between the first rotating shaft and the output shaft of the drive motor 610 more direct and efficient. The first bolt hole 622 is used to fix the first rotating shaft, and the second bolt hole 623 is used to fix an output shaft of the drive motor 610. The bolt connection ensures a stable connection between the rotating shaft and the output shaft. This stable connection helps to reduce vibration and noise and improve the operating stability of the entire system. The design of the bolt hole makes the connector have certain adaptability and flexibility. According to actual needs, the position and number of the bolt holes can be adjusted to adapt to different models and specifications of the first rotating shaft and the output shaft of the drive motor 610. This design improves the versatility and scalability of the system. When the rotating shaft or the output shaft needs to be maintained or replaced, the connector can be disassembled by simply loosening the bolts, which is convenient for maintenance operations. At the same time, due to the simple structure of the connector, the replacement process also becomes relatively easy and quick.

[0164] Optionally, the second connector 630 includes a second cylinder 631 , and a third bolt hole 632 and a fourth bolt hole 633 are formed on a side wall of the second cylinder 631 . The third bolt hole 632 is suitable for fixing the second rotating shaft, and the fourth bolt hole 633 is suitable for fixing another output shaft of the driving motor 610 .

[0165] By adopting a cylindrical structure as the second connector 630, it has the advantages of simple structure, convenient assembly, stable operation, and easy maintenance.

[0167] When using the duct type air conditioner indoor unit provided by the embodiment of the present disclosure, the driving motor 610 is fixed to the middle partition 130 through the motor fixing base 400. When the motor rotates, it is not easy to cause resonance of the shell 100, which can reduce the operating noise of the duct type air conditioner indoor unit.

[0168] Optionally, combined Figure 12 to Figure 14As shown, the motor fixing seat 400 includes a base plate 430, a first side plate 410, a second side plate 420 and a clamp assembly 500, wherein the base plate 430 is connected to the middle partition plate 130; the first side plate 410 extends outward from the base plate 430, and the first side plate 410 is provided with a first avoidance gap 411; the second side plate 420 extends outward from the base plate 430 and is opposite to the first side plate 410, and the second side plate 420 is provided with a second avoidance gap 421, and the two ends of the driving motor 610 are respectively clamped into the first avoidance gap 411 and the second avoidance gap 421; the clamp assembly 500 is used to clamp the two ends of the driving motor 610 in the first avoidance gap 411 and the second avoidance gap 421.

[0169] The middle partition 130 is arranged along the length direction of the housing 100, and the rotating shaft of the fan is also along the length direction of the housing 100. The base plate 430 of the motor fixing seat 400 is used to connect the middle partition 130. Exemplarily, the base plate 430 of the motor fixing seat 400 is connected to the middle partition 130 by bolts.

[0170] The first side plate 410 and the second side plate 420 of the motor fixing seat 400 are arranged opposite to each other, and an installation space is formed between the first side plate 410 and the second side plate 420 .

[0171] The first side plate 410 is provided with a first avoidance notch 411, the second side plate 420 is provided with a second avoidance notch 421, the drive motor 610 is arranged in the installation space, and the two ends are respectively clamped into the first avoidance notch 411 and the second avoidance notch 421. The clamp assembly 500 clamps the two ends of the drive motor 610 into the first avoidance notch 411 and the second avoidance notch 421.

[0172] The motor fixing seat 400 is firmly connected to the middle partition plate 130 through the base plate 430, providing a stable support foundation for the drive motor 610. This design effectively reduces the vibration generated by the motor during operation, thereby reducing the noise generated thereby. The first side plate 410 and the second side plate 420 are respectively provided with a first avoidance gap 411 and a second avoidance gap 421. This design enables the two ends of the drive motor 610 to be easily inserted into the corresponding avoidance gaps. This snap-in fixing method is not only convenient for installation, but also can adapt to drive motors 610 of different sizes and models, thereby improving the adaptability and flexibility of the system. The function of the clamp assembly 500 is to tightly clamp the two ends of the drive motor 610 in the first avoidance gap 411 and the second avoidance gap 421. This design ensures that the motor will not loosen or move during operation, thereby improving the tightness and safety of the entire system. Due to the stable design of the motor fixing seat 400 and the tight fixation of the clamp assembly 500, the vibration of the drive motor 610 during operation is effectively suppressed, thereby reducing the noise generated thereby. This is of great significance for improving the overall operation stability and user experience of the indoor unit. The modular design of the motor fixing base 400 allows for easy removal and installation of related components when the drive motor 610 needs to be repaired or replaced, thereby improving the convenience of maintenance.

[0173] Optionally, the clamp assembly 500 includes a first upper clamp 510 and a first lower clamp 520, wherein the first upper clamp 510 has a first end that is detachably connected to the first side plate 410, and the connection position is located on one side of the first avoidance notch; the first lower clamp 520 has a first end that is detachably connected to the first side plate 410, and the connection position is located on the other side of the first avoidance notch 411, and the second end of the first upper clamp 510 is connected to the second end of the first lower clamp 520.

[0174] Through the cooperation of the first upper clamp 510 and the first lower clamp 520, the two ends of the drive motor 610 are firmly clamped in the first avoidance gap 411. This form of upper and lower clamp enclosure can make the clamp assembly 500 easy to disassemble and assemble. The clamp assembly 500 can be easily disassembled and installed, which improves the convenience of maintenance. Since the clamp assembly 500 is detachable, the position and tightness of the clamp can be adjusted according to different sizes and models of drive motors 610 to meet different installation requirements. This design improves the adaptability and flexibility of the system. The stable clamp assembly 500 helps to reduce the vibration and noise of the drive motor 610 during operation. By tightly fixing the motor, the noise caused by looseness or displacement can be reduced, thereby improving the overall operating stability of the indoor unit.
