Compared with the traditional method of installing a fresh air device and other structures on the main unit, while enabling the air conditioner indoor unit to introduce fresh air and exhaust indoor polluted air, there is no fresh air fan occupying the internal space of the air conditioner indoor unit, which makes the components of the main unit fewer, reduces costs, and has a smaller overall volume and higher space utilization rate. At the same time, the fan assembly can drive the outdoor air flow to flow into the diversion air duct from the fresh air inlet, flow through the sub-unit air duct through the air outlet and then be blown out from the air inlet, and is used to drive the indoor air flow to enter the sub-unit air duct from the air inlet, flow through the diversion air duct through the air outlet and then be blown out from the fresh air inlet.

[0042] It should be noted that if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, such descriptions of "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and / or" appearing throughout the text is that it includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution that satisfies both A and B simultaneously.

[0043] The present invention provides an air conditioner indoor unit, which can specifically be a wall-mounted air conditioner indoor unit, a floor-standing air conditioner indoor unit, etc. The following will take the floor-standing air conditioner indoor unit as an example for exemplary illustration.

[0044] In the embodiments of the present invention, as Figures 1 to 6 , Figure 10 and Figure 11As shown in the figure, the air conditioner indoor unit includes a main unit 100 and a sub-unit 200. The main unit 100 includes an indoor heat exchange module. The main unit 100 is formed with a diversion air duct 110 and a fresh air inlet 120, and the fresh air inlet 120 communicates the diversion air duct 110 with the outside. The sub-unit 200 is detachably installed on the main unit 100, and when the sub-unit 200 is separated from the main unit 100, the sub-unit 200 can work independently. The sub-unit 200 is provided with an air inlet 210, an air outlet 220, and a sub-unit air duct 230 connecting the air inlet 210 and the air outlet 220. A fan assembly 240 is provided in the sub-unit air duct 230. When the sub-unit 200 is installed on the main unit 100, the air outlet 220 communicates with the diversion air duct 110, and the fan assembly 240 is used to drive the outdoor air flow to flow into the diversion air duct 110 from the fresh air inlet 120, flow through the sub-unit air duct 230 through the air outlet 220 and then be blown out from the air inlet 210, and is used to drive the indoor air flow to enter the sub-unit air duct 230 from the air inlet 210, flow through the diversion air duct 110 through the air outlet 220 and then be blown out from the fresh air inlet 120.

[0045] In this embodiment, the overall shapes of the main unit 100 and the sub-unit 200 can be cylindrical, elliptical cylindrical, square cylindrical or other shapes. The shapes of the main unit 100 and the sub-unit 200 can be the same or different. Specifically, it can be selected and designed according to actual use requirements and is not limited here. The main unit 100 extends in the up and down direction as a whole. The main unit 100 and the sub-unit 200 can be provided with equal cross-sections or variable cross-sections in the up and down direction. A heat exchange air duct is provided in the main unit 100, and the indoor heat exchange module is installed in the heat exchange air duct and is used to exchange heat with the air flow flowing through the heat exchange air duct to achieve refrigeration or heating. The indoor heat exchange module can only have a refrigeration function or can also have both refrigeration and heating functions. It can be understood that the main unit 100 also includes a heat exchange air inlet and a heat exchange air outlet communicating with the heat exchange air duct. The indoor heat exchange module includes a heat exchanger and a heat exchange fan. The heat exchange fan drives the air flow to enter the heat exchange air duct from the heat exchange air inlet, and after heat exchange through the heat exchanger, it is blown out from the heat exchange air outlet, thereby realizing indoor refrigeration or heating. The other specific structures of the air conditioner indoor unit can refer to the existing technologies and will not be elaborated here.

[0046] The slave unit 200 is detachably mounted on the master unit 100. Then, the slave unit 200 can be connected inside the master unit 100. For example, a receiving cavity 140 is provided inside the master unit 100 so that the slave unit 200 is mounted inside the receiving cavity 140. At this time, the receiving cavity 140 can be located at the upper, middle or lower part of the master unit 100. The slave unit 200 can also be connected to the outside of the master unit 100, such as being spliced at the bottom, top, peripheral side surface, etc. of the master unit 100. The connection between the slave unit 200 and the master unit 100 can be a structural connection. For example, it can be connected by means of snap connection, magnetic attraction connection, plug connection, etc. The connection between the slave unit 200 and the master unit 100 can also be only a connection of channels. For example, the air duct of the slave unit 230 of the slave unit 200 is communicated with the air duct inside the master unit 100, such as the fresh air duct, heat exchange air duct, etc. of the master unit 100. It can be understood that the slave unit 200 can be separated from the master unit 100 by the user's manual disassembly method, or the slave unit 200 can be actively separated from the master unit 100 by the control device without the user's manual operation. When the slave unit 200 is separated from the master unit 100, it can move circularly in the room independently and work independently to meet the needs of the whole indoor air treatment and make the air supply in the whole space uniform. It can also be manually moved by the user to move the slave unit 200 to the required position in the room or make the slave unit 200 move to a certain position independently, such as an area where many people gather, so as to be able to meet the fixed-point air supply in a certain area, realize long-distance, fixed-point and directional air supply, and improve the air treatment effect. Compared with moving the whole floor-standing air conditioner indoor unit, the movement of the slave unit 200 is more flexible and convenient, so as to be able to meet the different usage needs of users. Moreover, the slave unit 200 can relay the air flow blown out from the heat exchange air outlet 220 of the master unit 100, so that the air supply distance is farther and the air supply range is wider.

[0047] It can be understood that the air inlet 210 of the slave unit 200 is communicated with the room. When the slave unit 200 is installed in the receiving cavity 140 of the master unit 100, the receiving cavity 140 has an opening, or a through hole is opened on the housing of the master unit 100 so that the indoor air flow can enter the air duct 230 of the slave unit 200 from the air inlet 210. When the slave unit 200 is installed on the master unit 100, the air outlet 220 is communicated with the diversion air duct 110. Then, the diversion air duct 110 has an air passing opening 130. The air outlet 220 can be hermetically docked with the air passing opening 130 of the diversion air duct 110, or the air outlet 220 and the air passing opening 130 of the diversion air duct 110 can be arranged with a gap, so that the air outlet 220 faces the air passing opening 130 of the diversion air duct 110. Then, all or most of the air flow blown out from the air outlet 220 can flow into the diversion air duct 110, or most or all of the air flow flowing out from the air passing opening 130 can be introduced into the air duct 230 of the slave unit.

[0048] The blower assembly 240 may specifically include one blower. By switching the forward and reverse rotation of the blower, the exhaust mode and the fresh air mode can be switched. Of course, the direction of the air flow inside the sub-machine air duct 230 can also be switched by switching the position of the blower or setting up an air outlet switching mechanism, so as to realize the switching between the exhaust mode and the fresh air mode. The blower assembly 240 may also specifically include two blowers. Then, the sub-machine air duct 230 can be divided into a fresh air duct and an exhaust duct. By arranging one blower in each of the sub-machine air duct 230 and the exhaust duct, and making the air supply directions of the two opposite, the switching between the exhaust mode and the fresh air mode can be realized.

[0049] In the air conditioner indoor unit of the present invention, the sub-machine 200 is detachably installed on the main machine 100, and the sub-machine 200 can work independently away from the main machine 100. While ensuring rapid heat exchange in the whole room, the sub-machine 200 can be separated from the main machine 100 to realize whole-house mobile air supply, etc. Then, the air supply requirements of a certain area or the whole area in the room can be flexibly adjusted through the sub-machine 200, so that the flexibility of the whole air conditioner indoor unit is high, and different air supply requirements of users can be met. Moreover, the sub-machine 200 can perform relay air supply on the heat exchange air flow blown out by the main machine 100, so as to achieve long-distance and multi-directional air supply. At the same time, while enabling the air conditioner indoor unit to supply air in multiple directions, over a long distance, and throughout the house, the sub-machine 200 is installed on the main machine 100, so as to realize the integration of multiple machines for storage, save room space, and improve space utilization rate.

[0050] In addition, only one diversion air duct 110 communicating with the outside through the fresh air inlet 120 is provided on the main machine 100, and the fresh air mode and the exhaust mode of the whole air conditioner indoor unit are realized by using the sub-machine air duct 230 of the sub-machine 200 and the blower assembly 240 of the sub-machine 200. Compared with the traditional method of installing a fresh air device and other structures on the main machine 100, while enabling the air conditioner indoor unit to introduce fresh air and exhaust indoor dirty air, there is no fresh air blower occupying the internal space of the air conditioner indoor unit, so that the main machine 100 has fewer components, reduces costs, and has a smaller overall volume and higher space utilization rate. At the same time, the blower assembly 240 can drive the outdoor air flow to flow from the fresh air inlet 120 into the diversion air duct 110, flow through the sub-machine air duct 230 through the air outlet 220 and then be blown out from the air inlet 210, and is used to drive the indoor air flow to enter the sub-machine air duct 230 from the air inlet 210, flow through the diversion air duct 110 through the air outlet 220 and then be blown out from the fresh air inlet 120. That is, only through the cooperation of one fresh air inlet 120, diversion air duct 110, sub-machine air duct 230 and blower assembly 240, the switching between the exhaust mode and the fresh air mode of the whole air conditioner indoor unit is realized. Compared with the structure of a one-suction-one-exhaust double pipe system communicating with the outside, the number of holes drilled on the user's installation wall is reduced, and the user experience is improved.

[0051] In one embodiment, please refer to Figure 6, Figure 8 and Figure 11 , the fan assembly 240 includes a first axial-flow impeller 241 and a second axial-flow impeller 242. The air supply directions of the first axial-flow impeller 241 and the second axial-flow impeller 242 are the same, while the rotation directions are opposite. The first axial-flow impeller 241 and the second axial-flow impeller 242 can rotate clockwise or counterclockwise.

[0052] In this embodiment, the fan assembly 240 includes a first axial-flow impeller 241 and a second axial-flow impeller 242. The air supply directions of the first axial-flow impeller 241 and the second axial-flow impeller 242 are the same, while the rotation directions are opposite. Then this fan is a contra-rotating fan. That is, the rotation directions of the first axial-flow impeller 241 and the second axial-flow impeller 242 are opposite, and the helix directions of the blades of the first axial-flow impeller 241 and the second axial-flow impeller 242 on the hub are also opposite, so that the air supply directions of the two are the same. Further, the first axial-flow impeller 241 and the second axial-flow impeller 242 are coaxially arranged. The fan assembly 240 specifically further includes motors. There can be two motors, and the two motors are installed in an opposed-axis manner, providing power for the first axial-flow impeller 241 and the second axial-flow impeller 242 respectively. By making the fan assembly 240 adopt a contra-rotating fan, the air volume of the slave unit 200 can be increased. And because the first axial-flow impeller 241 and the second axial-flow impeller 242 are coaxially installed, the structure is compact and the axial dimension is small, so that the volume of the slave unit 200 is smaller. And making the first axial-flow impeller 241 and the second axial-flow impeller 242 can rotate clockwise or counterclockwise, that is, this contra-rotating fan is a bidirectional reversible contra-rotating fan. Then when the first axial-flow impeller 241 rotates clockwise and the second axial-flow impeller 242 rotates counterclockwise, so that the air supply directions of the two are towards one side, the whole air-conditioning indoor unit is in one of the fresh air mode and the exhaust mode. And when the first axial-flow impeller 241 rotates counterclockwise and the second axial-flow impeller 242 rotates clockwise, so that the air supply directions of the two are towards the other side, the whole air-conditioning indoor unit is in the other of the fresh air mode and the exhaust mode.

[0053] By making the fan assembly 240 include a first axial-flow impeller 241 and a second axial-flow impeller 242, and making the first axial-flow impeller 241 and the second axial-flow impeller 242 form a contra-rotating impeller, only need to install this contra-rotating impeller into the slave unit air duct 230. By switching the rotation direction of the contra-rotating impeller, the switching of the fresh air mode and the exhaust mode of the whole air-conditioning indoor unit can be realized. The structure is simple and easy to control. Compared with the fan assembly 240 adopting other fans and additionally setting channels to realize the switching of the fresh air mode and the exhaust mode through a wind direction switching device, there is no need to add an additional switching structure, and only need to open an air inlet 210, an air outlet 220 and a fresh air inlet 120 to realize the switching of the fresh air mode and the exhaust mode. The structural design is simpler and more reliable.

[0054] Further, as Figures 5 to 11 shown, the host 100 is further provided with an air passing opening 130 communicating with the air guiding air duct 110. The air conditioner indoor unit further includes a sealing structure 300. When the slave unit 200 is installed on the host 100, the sealing structure 300 is used to sealingly dock the air passing opening 130 and the air outlet 220.

[0055] In this embodiment, the shape and size of the air passing opening 130 and the air outlet 220 may be the same or different. Of course, for the convenience of docking the air passing opening 130 and the air outlet 220, optionally, the shape and size of the air passing opening 130 are made to be the same as those of the air outlet 220. The shape of the air outlet 220 may be circular, oval, rectangular, etc. To make the sealing effect of the sealing structure 300 better, optionally, the shapes of the air outlet 220 and the air passing opening 130 are made circular. The sealing structure 300 may be installed on the host 100, or on the slave unit 200, or the sealing structure 300 may be provided on both the host 100 and the slave unit 200. The sealing structure 300 may include structures such as a rubber ring and a sealing cylinder. The sealing structure 300 may be fixedly installed on the host 100 and / or the slave unit 100, or may be movably installed on the host 100 and / or the slave unit 200. The size of the sealing structure 300 should be greater than or equal to the air outlet 220 and the air passing opening 130 to be able to achieve a complete sealing docking of the air outlet 220 and the air passing opening 130. The sealing structure 300 sealingly docking the air passing opening 130 and the air outlet 220 means that the sealing structure 300 surrounds the outer periphery or edge of the air passing opening 130 and the air outlet 220, so that the air flow blown out from the air outlet 220 can completely blow into the air passing opening 130, or the air flow of the air passing opening 130 can completely blow into the air outlet 220. By sealingly docking the air passing opening 130 and the air outlet 220 through the sealing structure 300 when the slave unit 200 is installed on the host 100, the air passing opening 130 and the air outlet 220 can be sealingly docked, preventing the air flow of the air passing opening 130 or the air outlet 220 from flowing out through the gap between the air passing opening 130 and the air outlet 220, reducing the air volume loss, and thus improving the air volume of the air conditioner indoor unit in the fresh air mode and the exhaust air mode.

[0056] In one embodiment, please refer to Figures 1 to 6, the air outlet 220 is provided at the upper end of the slave unit 200, and the air passing opening 130 is located above the slave unit 200. By arranging the air outlet 220 at the upper end of the slave unit 200 and the air passing opening 130 above the slave unit 200, that is, at least part of the air guiding channel is located above the slave unit 200. In this way, when the slave unit 200 is installed on the main unit 100, the air outlet 220 above the slave unit 200 is directly docked with the air passing opening 130, so that the fan assembly 240 can send air upward or draw air downward, thus making full use of the space between the slave unit 200 and the main unit 100 in the up and down directions, and further making the layout of the main unit 100 and the slave unit 200 more reasonable. Then the air inlet 210 of the slave unit 200 can be specifically opened on the peripheral side wall of the slave unit 200. In other embodiments, the air outlet 220 can also be opened on the peripheral side wall of the slave unit 200.

[0057] Further, as Figures 5 to 9 shown, the sealing structure 300 is movably installed on the main unit 100 in the vertical direction, so as to have a first position received in the air guiding duct 110 and a second position for sealing and docking the air passing opening 130 and the air outlet 220.

[0058] In this embodiment, a lifting mechanism can be provided to drive the sealing structure 300 to move up and down. It can be understood that, in order to facilitate the installation and detachment of the slave unit 200 from the main unit 100, when the slave unit 200 is installed on the main unit 100, there is a certain gap between the top wall of the slave unit 200 and the wall surface of the main unit 100 provided with the air passing opening 130 to prevent movement interference. By movably installing the sealing structure 300 on the main unit 100 in the vertical direction and enabling the sealing structure 300 to have a first position received in the air guiding duct 110, after the slave unit 200 is detached from the main unit 100 or when the slave unit 200 needs to be detached from the main unit 100, the sealing structure 300 can be lifted into the air guiding duct 110. On the one hand, it is convenient for the slave unit 200 to be reset on the main unit 100 or the slave unit 200 to be detached from the main unit 100. On the other hand, the sealing structure 300 is hidden in the air guiding duct 110. After the slave unit 200 is detached from the main unit 100, the appearance of the main unit 100 is made more beautiful, and at the same time, the space in the air guiding duct 110 is fully utilized to make the overall structure more compact. When the slave unit 200 is installed on the main unit 100 and the fresh air mode and the exhaust mode need to be turned on, only by lowering the sealing structure 300 to the second position can the air passing opening 130 and the air outlet 220 be sealed and docked to increase the air volume in the fresh air mode and the exhaust mode.

[0059] Specifically, please refer to Figures 5 to 9 , the air conditioner indoor unit further includes a driving device 400 connected to the sealing structure 300. The driving device 400 is installed on the main unit 100 to drive the sealing structure 300 to switch between the first position and the second position.

[0060] In this embodiment, the driving device 400 may specifically include a driving motor and a rack and pinion structure. The driving motor is fixedly connected to the gear, the gear meshes with the rack structure, the driving motor is installed on the main body 100, and the rack structure is fixedly connected to the sealing structure 300, so as to realize driving the rack structure to move up and down through the driving motor, and further driving the sealing structure 300 to switch between the first position and the second position. The structure is simple and easy to implement. In other embodiments, the driving motor and the gear structure may also be fixed to the sealing structure 300, and the rack structure is installed on the main body 100, and the sealing structure 300 can also be switched between the first position and the second position. Driving the sealing structure 300 to switch between the first position and the second position through the driving device 400 makes the control of the entire air conditioner indoor unit more intelligent. Of course, the first position and the second position of the sealing structure 300 can also be manually switched.

[0061] On the basis of the above embodiment in which the air conditioner indoor unit further includes a driving device 400 connected to the sealing structure 300, further, please refer again to Figures 5 to 9 , the sealing structure 300 includes a lifting cylinder 310 and a sealing ring 320. The sealing ring 320 is connected to the lower end of the lifting cylinder 310, and the driving device 400 is connected to the lifting cylinder 310 to drive the lifting cylinder 310 to switch between the first position and the second position from the air passing opening 130.

[0062] In this embodiment, the sealing ring 320 may specifically be a rubber ring, and the lifting cylinder 310 is made of a hard material, specifically, it may be hard plastic or metal, etc. The sealing ring 320 may specifically be bonded to the lower end of the lifting cylinder 310, or may be fixed to the lower end of the lifting cylinder 310 by embedding or clamping. It can be understood that the sealing structure 300 only contacts the slave unit 200 through the sealing ring 320, thereby avoiding scratching the outer surface of the slave unit 200 by the lifting cylinder 310. By making the sealing structure 300 a combined structure of a lifting cylinder 310 and a sealing ring 320, compared with the structure where the sealing structure 300 is all a lifting cylinder 310, the sealing effect is better, and the scratching of the housing of the slave unit 200 can be reduced. And compared with the sealing structure 300 that is all a sealing ring 320, it can prevent the overall deformation of the sealing structure 300 from seriously affecting the sealing effect, and thus ensure the sealing effect of the entire sealing structure 300.

[0063] In one embodiment, as Figures 1 to 5 described, the main body 100 extends in the up and down direction, and a receiving cavity 140 is further provided in the main body 100, and the slave unit 200 is detachably installed in the receiving cavity 140.

[0064] In this embodiment, the accommodation cavity 140 can be located at the upper, middle or lower part of the host 100. The accommodation cavity 140 can be located below or above the heat exchange air duct. Of course, in a specific model, the accommodation cavity 140 can also be arranged side by side with the heat exchange air duct in the horizontal direction. Generally, the shape of the accommodation cavity 140 is adapted to the shape of the slave unit 200, that is, in the non-working state, the slave unit 200 is completely accommodated in the accommodation cavity 140. Of course, a part of the slave unit 200 can also be located inside the accommodation cavity 140 and a part can be located outside the accommodation cavity 140, that is, a part is exposed outside the host 100. The accommodation cavity 140 can be formed by partially hollowing out the host 100. The accommodation cavity 140 can also be formed by enclosing with support arms on the host 100. At this time, the diversion air duct 110 is located above the slave unit 200. By arranging at least a part of the slave unit 200 in the accommodation cavity 140 of the host 100, compared with the overall splicing of the slave unit 200 and the host 100, it is easier to maintain the overall consistency after the two are connected, thereby improving the user experience.

[0065] The slave unit 200 is detachably installed in the accommodation cavity 140. Then, the slave unit 200 can be directly placed in the accommodation cavity 140 and separated from the accommodation cavity 140 by means of rolling, sliding, etc. The slave unit 200 can also be limit-installed in the accommodation cavity 140 through a limiting structure, such as being connected in the accommodation cavity 140 by means of snap connection, magnetic attraction connection, etc. There are many forms for the slave unit 200 to be installed in the accommodation cavity 140 and separated from the accommodation cavity 140, which will not be listed one by one here. The user can manually move the slave unit 200 out of the accommodation cavity 140, so that the slave unit 200 is separated from the host 100. It is also possible to control the slave unit 200 to autonomously move out of the host 100. At this time, the accommodation cavity 140 needs to be arranged at the bottom of the host 100 so that the slave unit 200 can autonomously move out of the accommodation cavity 140.

[0066] It can be understood that the accommodation cavity 140 has an opening, and the slave unit 200 enters and exits the accommodation cavity 140 through this opening. Then, when the air conditioner indoor unit needs to turn on the exhaust mode, the indoor air flow can flow into the air inlet 210 of the slave unit 200 from the opening of the accommodation cavity 140 and be blown into the diversion air duct 110 through the air outlet 220. And when the air conditioner indoor unit needs to turn on the fresh air mode, the outdoor air flow flowing into the slave unit air duct 230 from the fresh air inlet 120 can be blown towards the opening of the accommodation cavity 140 through the air inlet 210 of the slave unit 200 to enter the room. A switch door can be arranged at the opening of the accommodation cavity 140, and the switch door can be opened when the air conditioner indoor unit needs to turn on the exhaust mode and the fresh air mode. A gas circulation port corresponding to the air inlet 210 of the slave unit 200 can also be arranged on the housing to allow the air flow to flow into the room.

[0067] In one embodiment, please refer to Figure 10 and Figure 11, the diversion air duct 110 includes a first air duct 111 and a second air duct 112 that are connected to each other. The first air duct 111 extends horizontally and is located above the accommodation cavity 140, and the second air duct 112 extends vertically.

[0068] In this embodiment, by making the diversion air duct 110 include the first air duct 111 extending horizontally and the second air duct 112 extending vertically, the dimensions and space in the height and width directions of the main unit 100 can be fully utilized, and thus the structure of the main unit 100 can be made more compact while meeting the diversion requirements. It can be understood that the diversion air duct 110 can be defined within the housing of the main unit 100, or an additional air duct housing can be provided and installed on the housing of the main unit 100 to define the diversion air duct 110 within the air duct housing. For the convenience of air duct processing, optionally, the main unit 100 includes an air duct housing and a housing. An accommodation cavity 140 is defined within the housing, the air duct housing is installed on the housing, and the air duct housing and the housing jointly define the diversion air duct 110. Specifically, the air duct housing includes a connecting panel and a surrounding frame. The first air duct 111 is defined within the surrounding frame, and the panel is installed within the accommodation cavity 140 and jointly defines the second air duct 112 with the housing.

[0069] Furthermore, as Figure 10 and Figure 11 shown, there are at least two fresh air inlets 120, and at least two of the fresh air inlets 120 are spaced apart in the extending direction of the second air duct 112. Specifically, two fresh air inlets 120 are provided, and both of the two fresh air inlets 120 are communicated with the second air duct 112. By making the two fresh air inlets 120 spaced apart in the extending direction of the second air duct 112, the gas flow rate in the fresh air mode and the exhaust air mode can be increased, and thus the ventilation efficiency and effect in the fresh air mode and the exhaust air mode can be improved.

[0070] In one embodiment, an indoor air outlet is further provided on the main unit 100, and the fan assembly 240 is further configured to drive indoor air flow to enter the sub-air duct 230 from the air inlet 210 and blow it out into the room through the indoor air outlet. By providing an indoor air outlet on the main unit 100, the fan assembly 240 can drive indoor air flow to enter the sub-air duct 230 from the air inlet 210, and after being processed by the air treatment module in the sub-air duct 230, it is blown out from the air outlet 220 and then blown out into the room through the indoor air outlet. In this way, the indoor unit of the air conditioner also has an indoor air circulation mode, thereby increasing the operating modes of the indoor unit of the air conditioner and improving the user experience.

[0071] Specifically, please refer to Figure 10 and Figure 11, one or more of a heating module, a humidifying module, and a purification module are provided in the air guiding duct 110. The heating module may specifically be an electric heating device, the humidifying module may specifically be a wet film assembly, and the purification module may specifically include a HEPA filter, etc. By providing the heating module in the air guiding duct 110, the fresh air entering the air guiding duct 110 can be heated, thereby avoiding the influence on the indoor temperature caused by introducing fresh air when the outdoor temperature is relatively low. By providing the humidifying module in the air guiding duct 110, the fresh air flow can be humidified, thereby meeting the demand for fresh air when the indoor air is dry. By providing the purification module in the air guiding duct 110, the fresh air in the air guiding duct 110 can be filtered and then flow into the room, thereby ensuring the health of users.

[0072] In one embodiment, as Figure 6 , Figure 8 , Figure 10 and Figure 11 shown, one or more of a humidifying module, a dehumidifying module, a heating module, a purification module, a flavoring module, and an anti-allergen module are provided in the sub-machine duct 230. The humidifying module may specifically be a wet film assembly, the heating module may specifically be an electric heating assembly, the purification module may specifically include a plasma module, a negative ion module, a sterilization module, an electrostatic precipitation module, and a filter module, such as a HEPA filter, etc. The anti-allergen module may specifically include a dust removal module, a dust mite removal module, etc. Users can select to provide different air treatment modules in the sub-machine duct 230 according to the usage requirements. And when the fresh air module and the exhaust mode of the air conditioner indoor unit are turned on, the air treatment module in the sub-machine duct 230 can be borrowed for air treatment to meet more usage requirements of users.

[0073] In one embodiment, please refer to Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 , Figure 10 and Figure 11 , the sub-machine 200 includes a sub-machine body 250, a control device, and a moving device 260. The sub-machine duct 230 is provided in the sub-machine body 250. The moving device 260 is installed at the bottom of the sub-machine body 250. The control device is used to control the moving device 260 to drive the sub-machine body 250 to move.

[0074] In this embodiment, the mobile device 260 can be installed at the bottom of the slave unit body 250, or the support arm can be connected to the side wall or the top of the slave unit body 250. The support arm extends towards the bottom of the slave unit body 250, and the mobile device 260 is installed at the bottom end of the support arm to drive the slave unit body 250 to move. Specifically, the mobile device 260 can be in the form of a driving wheel plus a universal wheel, a roller plus a turntable, etc. Then, the mobile device 260 can drive the slave unit 200 to move and turn, so as to achieve multi-directional movement in the entire room. The control device can be specifically installed on or inside the slave unit body 250. Then, the user can send a signal to the control device by means of wireless transmission or infrared remote control, etc., and further control the movement of the mobile device 260. A program can also be written into the control main board to enable the slave unit 200 to move autonomously. It can be understood that the movement of the slave unit 200 can be controlled in real time by means of remote control by a remote control, mobile phone APP remote control, etc., or the position, time, movement path, etc. of the slave unit 200 to move can be preset. Obstacle avoidance sensors such as infrared sensors and ultrasonic sensors can also be set on the slave unit 200, so that the slave unit 200 can avoid obstacles and turn to move autonomously, and the control device controls the slave unit 200 to have multiple action modes. Thus, the slave unit 200 is equivalent to an air-conditioning robot, and can adjust the movement direction according to the feedback of the indoor environment and autonomously plan the walking route, so as to ensure that the slave unit 200 can avoid obstacles and walk flexibly. Temperature, humidity or pollutant sensors can also be set, so that the slave unit 200 can detect the environmental state of a certain area during the movement process, and thus can autonomously judge whether to leave or stay to continue blowing air. Of course, a vision sensor can also be set on the slave unit 200. The slave unit 200 moves to take panoramic images of the house interior and can upload them to the cloud system. Then, the user can observe the movement of the slave unit 200 at any time through intelligent devices such as mobile phones, tablets, and computers. Of course, the above control device can also be used to control the slave unit 200 to detach from the host 100.

[0075] In one embodiment, the control device includes a controller and a sensor for receiving a roadblock signal. The controller is used to plan a walking route according to the roadblock signal of the sensor and control the mobile device 260 to drive the slave unit 200 to move.

[0076] Specifically, the sensor includes at least one of a laser sensor, a radar sensor, an infrared sensor, a ultrasonic sensor, an acoustic sensor, and a vision sensor. Specifically, a lidar can be disposed on the top of the slave unit 200, and the ultrasonic sensor can be disposed at the bottom of the slave unit body 250, so that the detection range of the lidar is wider and the detection accuracy of the ultrasonic sensor is higher. In this way, the detection effect and accuracy of the entire slave unit 200 are better. After the slave unit 200 disengages from the accommodation cavity 140, the sensor scans and detects the environment where the slave unit 200 is located, so as to understand the local area of the entire room and autonomously plan the walking route. And during the movement of the slave unit 200, the sensor also senses obstacles at a certain distance (such as furniture, steps, carpets and other objects that hinder the movement of the slave unit 200), and after sensing the obstacles, the slave unit 200 can perform operations such as backing and turning, so that it can avoid obstacles autonomously, effectively avoid collisions, and plan the walking route in real time according to the room conditions. In this way, it is ensured that the slave unit 200 can autonomously plan the walking route according to the complex indoor environment and adjust the walking mode according to the feedback of the indoor environment, so as to realize the flexible walking of the slave unit 200 indoors.

[0077] Specifically, temperature, humidity or pollutant sensors can also be disposed on the slave unit body 250, so that during the movement of the slave unit 200, the environmental state of a certain area can be detected, and thus it can autonomously determine whether to leave or stay for continuous air supply. For example, when it is detected that the temperature in the area where many people are concentrated is high, the dust in a certain area is large, the humidity is high or low, the slave unit 200 stays and performs continuous air supply, and selects the processing function of the air treatment module according to the feedback situation to realize the corresponding air treatment. When it is detected that the air parameters meet the requirements, it can leave to another area. In this way, it can meet the fixed-point air supply in a certain area, realize long-distance, fixed-point and directional air supply, and improve the air treatment effect. Of course, a vision sensor can also be disposed on the slave unit 200. The slave unit 200 moves to take panoramic images of the house interior and can upload them to the cloud system, so that the user can observe the movement of the slave unit 200 at any time through intelligent devices such as mobile phones, tablets, and computers. Compared with moving the entire floor-standing air conditioner indoor unit, the slave unit 200 can move autonomously and plan the walking route according to the environment, making the movement of the slave unit 200 more flexible and convenient, so as to meet the different usage requirements of users, with high intelligence and simple operation.
