[0045] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0046] It should be noted that if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text is to include three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B.

[0047] The invention provides an air-conditioner indoor unit.

[0048] See also Figures 1 to 3 The present invention provides an air conditioner indoor unit 300, which includes a main unit 200 and a sub-unit 100 detachably installed on the main unit 200. When the sub-unit 100 is separated from the main unit 200, the sub-unit 100 can work independently.

[0049] Among them, the overall shape of the host 200 and the sub-machine 100 can be cylindrical, elliptical, square or other shapes, and the shapes of the host 200 and the sub-machine 100 can be the same or different. It can be selected and designed according to the actual air treatment needs of the user, and is not limited here. The host 200 extends as a whole in the up and down direction, and the host 200 and the sub-machine 100 can be set with equal cross-sections or variable cross-sections in the up and down directions. A heat exchange duct is provided in the host 200, and an indoor heat exchange module is installed in the heat exchange duct to exchange heat with the airflow flowing through the heat exchange duct to achieve cooling or heating. The indoor heat exchange module can have only cooling function, or it can have cooling and heating functions at the same time. It can be understood that the host 200 also includes a heat exchange air inlet and a heat exchange air outlet 116 connected to 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 airflow from the heat exchange air inlet into the heat exchange air duct, and blows out from the heat exchange air outlet 116 after heat exchange in the heat exchanger, thereby achieving indoor cooling or heating. Other specific structures of the air conditioner indoor unit 300 can refer to existing technologies and will not be repeated here.

[0050] The sub-machine 100 can be installed detachably from the main machine 200, and the sub-machine 100 can be connected to the inside of the main machine 200, such as setting a receiving chamber 211 inside the main machine 200 so that the sub-machine 100 is installed in the receiving chamber 211, and the receiving chamber 211 can be located at the upper part, the middle part or the lower part of the main machine 200. The sub-machine 100 can also be connected to the outside of the main machine 200, such as being spliced ​​at the bottom, the top, the side surface, etc. of the main machine 200. The connection between the sub-machine 100 and the main machine 200 can be a structural connection, such as being connected by means of snap connection, magnetic connection, plug connection, etc. The connection between the sub-machine 100 and the main machine 200 can also be a channel connection only, such as making the sub-machine air duct of the sub-machine 100 communicate with the air duct in the main machine 200, such as the guide air duct and the heat exchange air duct of the main machine 200. It is understandable that the sub-machine 100 can be separated from the main machine 200 by manual disassembly by the user, or the sub-machine 100 can be actively separated from the main machine 200 by the control device without manual operation by the user. When the sub-machine 100 is separated from the main machine 200, the sub-machine 100 can be autonomously moved in a cycle in the room and work independently to meet the needs of the entire indoor air treatment and make the air supply uniform in the entire space. The sub-machine 100 can also be moved manually by the user to the required position in the room or the sub-machine 100 can be autonomously moved to a certain position, such as an area where many people gather, so as 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 entire floor-standing air conditioner indoor unit 300, the movement of the sub-machine 100 is more flexible and convenient, so as to meet the different air treatment needs of the user. And the sub-machine 100 can relay the air supply of the air flow blown out of the heat exchange outlet 116 of the main machine 200, so that the air supply distance is farther and the air supply range is wider.

[0051] The specific structure of the slave 100 will be described below. Figures 3 to 7 The sub-unit 100 includes a housing 110, a switching assembly 130, a first air processing module 140 and a second air processing module 150. The housing 110 is provided with a sub-unit air duct, and the sub-unit air duct includes at least two air processing chambers 112 and a fan chamber 115. The housing 110 is provided with an air inlet 111 communicating with the air processing chamber 112, and an air outlet 116 communicating with the fan chamber 115. The switching assembly 130 is used to connect or block the sub-unit air duct, so that at least one of the air processing chambers 112 is connected with the fan chamber 115; each of the air processing modules 140 is arranged in a corresponding air processing chamber 112.

[0052] In the embodiment of the invention, please refer to Figure 4 and Figure 5, the sub-machine air duct may include two air processing chambers 112, three air processing chambers 112 or more air processing chambers 112, which are not specifically limited here. Among them, at least two of the air processing chambers 112 can be arranged in the up and down direction, or in the horizontal direction, which are not specifically limited here. The shell 110 is provided with an air inlet 111 connected to the air processing chamber 112. It can be understood that the air inlet 111 is connected to each of the air processing chambers 112, and air can enter each of the air processing chambers 112 from the air inlet 111. Specifically, the air inlet 111 is provided on the peripheral side wall of the shell 110, and the number of the air inlet 111 can be one, two or more. In addition, the shape of the air inlet 111 can be various, for example, it can be circular, elliptical, square, triangular or other special shapes, which are not specifically limited. The air outlet 115 may have a variety of shapes, for example, circular, elliptical, square, triangular or other special shapes, and is not specifically limited. Without loss of generality, an air inlet grille may be provided at the air inlet 111, and an air outlet grille may be provided at the air outlet 115.

[0053] The air processing module 140 is mainly used to process the air, for example, but not limited to purification, humidification, sterilization, dehumidification, etc. The number of the air processing modules 140 is equal to the number of the air processing chambers 112 and is arranged correspondingly. It should be noted that the types and functions of at least two air processing modules 140 may be the same or different. Optionally, the air processing module 140 includes one or more combinations of a humidification module, a purification module, a sterilization module, and a dehumidification module. Among them, the purification module includes one or more combinations of a filter module, an electrostatic dust collection module, a negative ion module, and a plasma module. Specifically, the filter module may specifically include one or more combinations of a HEPA filter, an activated carbon filter, a plasma integrated network, a photocatalyst filter, and a formaldehyde filter.

[0054] The switching component 130 is used to connect or block the sub-machine air duct so that at least one of the air processing chambers 112 is connected to the fan chamber 115. It can be understood that the switching component 130 can connect one, two, three or more air processing chambers 112 to the fan chamber 115. If the switching component 130 connects one of the air processing chambers 112 to the fan chamber 115, the air enters the air processing chamber 112 from the air inlet 111, is processed by the air processing module 140 in the air processing chamber 112, flows through the fan chamber 115, and finally blows out from the air outlet 116, so that the single function processing of the air can be achieved. If the switching assembly 130 enables multiple air processing chambers 112 to communicate with the fan chamber 115, the air enters the multiple air processing chambers 112 from the air inlet 111, is processed by the air processing modules 140 in the multiple air processing chambers 112, flows through the fan chamber 115, and finally blows out from the air outlet 116, so that multiple functions of air processing can be achieved. In this way, by connecting at least one of the air processing chambers 112 to the fan chamber 115 through the switching device 130, multiple functions of air processing can be achieved, thereby meeting the diverse air processing needs of users.

[0055] It should be pointed out that the air processing chamber 112 and the fan chamber 115 are connected in two ways: one is that the air processing chamber 112 and the fan chamber 115 are directly connected, and the other is that the air processing chamber 112 and the fan chamber 115 are indirectly connected. In the embodiment of the present invention, the sub-machine 100 also includes a fan assembly 120, which is arranged in the fan chamber 115 to drive air to enter from the air inlet 111 and blow out from the air outlet 116. Among them, the fan assembly 120 can include a single wind wheel or a double wind wheel, which is not specifically limited. It will be described in detail below.

[0056] The air conditioner indoor unit 300 of the present invention comprises a main unit 200 and a sub-unit 100 detachably mounted on the main unit 200, wherein the sub-unit 100 comprises a housing 110, a switching assembly 130 and an air processing module 140, wherein the housing 110 is provided with a sub-unit air duct, wherein the sub-unit air duct comprises at least two air processing chambers 112 and a fan chamber 115, wherein the housing 110 is provided with an air inlet 111 communicating with the air processing chamber 112, and an air outlet 116 communicating with the fan chamber 115; the switching assembly 130 is used to connect or block the sub-unit air duct so that at least one air processing chamber 112 is connected with the fan chamber 115; each of the air processing modules 140 is arranged in a corresponding one of the air processing chambers 115; thus, in the switching assembly 130, the sub-unit air duct is connected with the fan chamber 115; When the component 130 connects one of the air processing chambers 112 with the fan chamber 115, air enters the air processing chamber 112 from the air inlet 111, is processed by the air processing module 140 in the air processing chamber 112, flows through the fan chamber 115, and finally blows out from the air outlet 116, so that single-function processing of air can be achieved; when the switching component 130 connects multiple air processing chambers 112 with the fan chamber 115, air enters multiple air processing chambers 112 from the air inlet, is processed by the air processing modules 140 in multiple air processing chambers 112, all flows through the fan chamber 115, and finally blows out from the air outlet 116, so that multiple-function processing of air can be achieved. Therefore, the sub-unit 100 of the air conditioner indoor unit 300 of the present invention can provide multiple air processing modes, thereby well meeting the diversified air processing needs of users.

[0057] The following will take two air processing chambers 112 as an example for detailed description. For the convenience of description, at least two air processing chambers 112 include a first air processing chamber 113 and a second air processing chamber 114. There are many ways to arrange the first air processing chamber 113, the second air processing chamber 114 and the fan chamber 115. For example, see Figure 5 In some embodiments, the first air processing chamber 113, the second air processing chamber 114, and the fan chamber 115 may be arranged in an up-down direction.

[0058] See also Fig. 9 and Fig.10In this embodiment, the switching component 130 is located between the first air processing chamber 113 and the second air processing chamber 114, so as to connect the first air processing chamber 113 and / or the second air processing chamber 114 with the fan chamber 115. The first air processing chamber 113 may be located below the second air processing chamber 114, and the fan chamber 115 is located above the second air processing chamber 114. The switching component 130 has a conducting position and a blocking position. When the switching component 130 is in the conducting position (such as Fig. 9 As shown in FIG. 1 , a portion of the air enters the first air processing chamber 113 from the air inlet 111, is processed by the air processing module 140 in the first air processing chamber 113, and flows into the fan chamber 115 through the second air processing chamber 114. Another portion of the air enters the second air processing chamber 114 from the air inlet 111, is processed by the air processing module 140 in the second air processing chamber 114, and flows into the fan chamber 115. Finally, both portions of air can be blown out from the air outlet 116. When the switching component 130 is in the blocking position (as shown in FIG. 1 ), a portion of the air enters the first air processing chamber 113 from the air inlet 111, and flows into the fan chamber 115 through the second air processing chamber 114. Fig.10 As shown), air only enters the second air processing chamber 114 from the air inlet 111, flows into the fan chamber 115 after being processed by the air processing module 140 in the second air processing chamber 114, and is finally blown out from the air outlet 116.

[0059] It can be understood that the first air processing chamber 113 can also be located above the second air processing chamber 114, and the fan chamber 115 is located above the first air processing chamber 113. When the switching component 130 is in the conducting position, a part of the air enters the second air processing chamber 114 from the air inlet 111, and flows into the fan chamber 115 through the first air processing chamber 113 after being processed by the air processing module 140 in the second air processing chamber 114, and another part of the air enters the first air processing chamber 113 from the air inlet 111, and flows into the fan chamber 115 after being processed by the air processing module 140 in the first air processing chamber 113, and finally both parts of the air can be blown out from the air outlet 116. When the switching component 130 is in the blocking position, the air only enters the first air processing chamber 113 from the air inlet 111, and flows into the fan chamber 115 after being processed by the air processing module 140 in the first air processing chamber 113, and finally blows out from the air outlet 116.

[0060] In this embodiment, the air inlet 111 includes a first air inlet 111a communicating with the first air processing chamber 113, and a second air inlet 111b communicating with the second air processing chamber 114. The first air inlet 111a is arranged on the peripheral side wall of the shell 110, and the number of the first air inlet 111a can be one, two or more. The second air inlet 111b is also arranged on the peripheral side wall of the shell 110, and the number of the second air inlet 111b can also be one, two or more. In addition, the shapes of the first air inlet 111a and the second air inlet 111b can be various, for example, they can be circular, elliptical, square, triangular or other special shapes, etc., and are not specifically limited.

[0061] For ease of description, the air processing module 140 located in the first air processing chamber 113 can be defined as a first air processing module, and the air processing module 140 located in the second air processing chamber 114 can be defined as a second air processing module. In one embodiment, the first air processing module mainly plays the role of humidifying air, and the first air processing module can specifically be a humidifying module, such as a wet film. The sub-machine 100 also includes a water tank, which is used to supply water to the first air processing module. Optionally, the first air processing module is arranged in an annular shape, and the first air processing module is arranged corresponding to the first air inlet 111a, so that the humidification area can be increased and the humidification efficiency can be increased. The second air processing module mainly plays the role of purifying air, and the second air processing module can specifically be a purification module. Optionally, the second air processing module can be arranged in an annular shape, and the second air processing module can be arranged corresponding to the second air inlet 111b, so that on the one hand, the purification area can be increased and the purification efficiency can be improved, and on the other hand, the resistance to the air can be reduced, thereby reducing the air volume loss.

[0062] In this embodiment, when the switching component 130 is in the on position (eg Fig. 9 As shown in the figure), the air entering from the first air inlet 111a is first humidified by the first air processing module, then flows through the second air processing chamber 114 and is purified by the second air processing module, and finally flows through the fan chamber 115 and is blown out through the air outlet 116, thereby realizing the air purification and humidification mode; when the switching component 130 is in the blocking position (as ... Fig.10 As shown in the figure, the air entering the first air processing chamber 113 from the first air inlet 111a cannot flow into the second air processing chamber 114. At this time, the air flowing into the second air processing chamber 114 from the second air inlet 111b is purified by the second air processing module and then flows to the fan chamber 115, and is finally blown out through the air outlet 116, thereby realizing a separate air purification mode.

[0063] It should be pointed out that in the purification and humidification mode, Fig. 9 As shown, part of the air enters the first air processing chamber 113 from the first air inlet 111a, is humidified by the first air processing module 140, and then flows into the second air processing chamber 114 and is purified by the second air processing module 150. At the same time, part of the air enters the second air processing chamber 114 from the second air inlet 111b and is directly purified by the second air processing module 150. After that, the two are mixed and blown out from the air outlet 116 through the fan chamber 115. In this way, the humidity of the indoor air can be ensured to be appropriate, and at the same time, wind loss can be reduced, thereby increasing the air volume, thereby improving the purification and humidification effect of the indoor air.

[0064] In this embodiment, the first air processing chamber 113 is located below the second air processing chamber 114, that is, the humidification module is located below the purification module, which is conducive to improving the overall stability of the sub-machine 100. Because the humidification module is generally heavy, installing the humidification module at the bottom of the sub-machine 100 can improve the overall stability of the sub-machine 100, so that the sub-machine 100 is not easy to tip over. In addition, in this embodiment, a water tank is provided at the bottom of the first air processing chamber 113, the humidification module is provided in the water tank, and the water tank is used to supply water to the water tank.

[0065] In addition, there may be various structures of the switching component 130. For example, see Figure 8 In one embodiment, the switching assembly 130 includes a fixed plate 131 and a movable plate 132, wherein the fixed plate 131 is connected to the housing 110, and the movable plate 132 is slidably connected to the fixed plate 131, so that the first air processing chamber 113 and / or the second air processing chamber 114 are connected to the fan chamber 115. Specifically, one end of the fixed plate 131 is connected to the housing 110, and the other end is slidably connected to the movable plate 132. In this way, by sliding the sliding plate, the first air processing chamber 113 and the second air processing chamber 114 can be connected or blocked, so that the first air processing chamber 113 and / or the second air processing chamber 114 are connected to the fan chamber 115.

[0066] In another embodiment, the switching assembly 130 includes a partition, and the partition is rotatably connected to the housing 110 to enable the first air processing chamber 113 and / or the second air processing chamber 114 to communicate with the fan chamber 115. Specifically, the partition can be turned upside down to connect or block the first air processing chamber 113 and the second air processing chamber 114, so that the first air processing chamber 113 and / or the second air processing chamber 114 are connected with the fan chamber 115. In order to reduce the space required for the partition to rotate, the partition can include a first sub-plate and a second sub-plate, and the first sub-plate and the second sub-plate are rotatably connected to the opposite side walls of the housing 110 respectively.

[0067] See also Fig.11 In other embodiments, the first air processing chamber 113 and the second air processing chamber 114 may also be arranged in the horizontal direction, and the fan chamber 115 is located above or below the first air processing chamber 113 and the second air processing chamber 114.

[0068] In this embodiment, the switching assembly 130 is rotatably connected to the housing 110, and the switching assembly 130 has a first connection position, a second connection position, and a third connection position. Fig.11 As shown in FIG. 1 , the switching assembly 130 connects the first air processing chamber 113 with the fan chamber, and connects the second air processing chamber 114 with the fan chamber 115. That is, the switching assembly 130 is located between the first air processing chamber 113 and the second air processing chamber 114.

[0069] When the switching assembly 130 is in the second connection position, the switching assembly 130 connects the first air processing chamber 113 with the fan chamber 115, and blocks the second air processing chamber 113 from the fan chamber 115. At this time, the switching assembly 130 rotates upward in a counterclockwise direction to the connection port between the second air processing chamber 114 and the fan chamber 115.

[0070] When the switching assembly 130 is in the third connection position, the switching assembly 130 connects the second air processing chamber 114 with the fan chamber 115, and blocks the first air processing chamber 113 from the fan chamber 115. At this time, the switching assembly 130 rotates upward in a clockwise direction to the connection port between the first air processing chamber 113 and the fan chamber 115.

[0071] In order to facilitate the movement of the switching component 130, the sub-machine 100 further includes a driving device, which is connected to the switching component 130 to drive the switching component 130 to move. There are also various structures and driving methods of the driving device. For example, the driving device includes a motor and a shaft assembly, and the motor drives the switching component 130 to rotate through the shaft assembly; or the driving device includes a motor and a gear assembly, and the motor drives the switching component 130 to rotate through the gear assembly. No specific limitation is made here, and reference may be made to the existing technology.

[0072] See also Figure 5 and Figure 6 , considering that the sub-machine air duct is provided with a second air processing module and a first air processing module, the air resistance is relatively large, and the air volume loss after passing through the second air processing module and the first air processing module is relatively large, that is, the air output is relatively small, so in order to increase the air output, in some embodiments, a double wind wheel can be selected. Specifically, the fan assembly 120 includes a first axial flow wind wheel 121 and a second axial flow wind wheel 122, and the first axial flow wind wheel 121 and the second axial flow wind wheel 122 have opposite rotation directions and the same air supply direction. Among them, the first axial flow wind wheel 121 and the second axial flow wind wheel 122 can rotate clockwise or counterclockwise. In this way, by adopting a double axial flow wind wheel, the air intake can be increased, thereby increasing the air output, and at the same time, the noise can be reduced.

[0073] In this embodiment, the first axial flow fan wheel 121 and the second axial flow fan wheel 122 rotate in opposite directions and have the same air supply direction, that is, the fan assembly 120 is a counter-rotating fan. The first axial flow fan wheel 121 and the second axial flow fan wheel 122 are coaxially arranged, and the bending direction of the blades of the first axial flow fan wheel 121 is opposite to the bending direction of the blades of the second axial flow fan wheel 122. Figure 5, the fan assembly 120 specifically includes a first motor 123 and a second motor 124, wherein the first motor 123 provides power for the first axial flow wind wheel 121, and the second motor 124 provides power for the second axial flow wind wheel 122. The first motor 123 and the second motor 124 can be coaxially arranged. In order to facilitate installation and save installation space, so that the installation of the fan assembly 120 is more compact, a first mounting frame 125 for mounting the first motor 123 and a second mounting frame 126 for mounting the second motor 124 are arranged in the fan cavity 115, the first axial flow wind wheel 121 is located on the side of the first mounting frame 125 away from the second mounting frame 126, and the second axial flow wind wheel 122 is located on the side of the second mounting frame 126 away from the first mounting frame 125. In addition, in order to take into account the functions of accommodating the motor and fixing the motor, and to facilitate the rotation of the axial flow wind wheel, the mounting frame (the first mounting frame 125 or the second mounting frame 126) can be arranged in an arc shape.

[0074] Further, in this embodiment, in order to reduce the noise of the counter-rotating fan and subject to the size limit of the sub-machine 100, the first axial flow fan wheel 121 and the second axial flow fan wheel 122 use multi-blade fans. The number of blades of the first axial flow fan wheel 121 is different from the number of blades of the second axial flow fan wheel 122. Optionally, the number of blades of the first axial flow fan wheel 121 and the number of blades of the second axial flow fan wheel 122 are prime numbers to each other, for example but not limited to, the number of blades of the first axial flow fan wheel 121 is 7, and the number of blades of the second axial flow fan wheel 122 is 9.

[0075] See also Figure 5 In one embodiment, the air outlet 116 is disposed on the upper surface of the housing 110, and the main unit 200 is provided with a guide air duct (not shown) connected to the air outlet 116. When the sub-unit 100 is installed on the main unit 200, the air outlet 116 is connected to the guide air duct, and the fan assembly 120 is used to drive air from the air outlet 116 to flow into the guide air duct. The guide air duct may be connected to the heat exchange air duct of the main unit 200, so that the processed air in the sub-unit air duct may be introduced into the heat exchange air duct of the main unit 200, and then blown out through the heat exchange air outlet 116. Of course, the guide air duct may not be connected to the heat exchange air duct of the main unit 200. For example, a fresh air inlet 212 (such as 212) may be provided on the housing 210 of the main unit 200. Figure 1As shown) and a fresh air outlet, the fresh air inlet 212 is connected to the accommodating chamber 211, and the fresh air outlet is connected to the guide air duct. When the sub-unit 100 is installed in the accommodating chamber 211 of the main unit 200, outdoor air enters the sub-unit air duct through the fresh air inlet 212 and the air inlet of the sub-unit 100 in sequence, then flows into the guide air duct from the air outlet 116, and finally flows into the room through the fresh air outlet, thereby realizing the function of introducing fresh air into the air conditioner indoor unit 300.

[0076] In addition, based on the above embodiments, the air conditioner indoor unit 300 includes a control device and a mobile device 150 (such as Figure 3 As shown), the mobile device 150 is installed at the bottom of the shell 110, and the control device is used to control the mobile device 150 to drive the shell 110 to move.

[0077] In this embodiment, the mobile device 150 can be specifically a combination of a driving wheel plus a universal wheel, a roller plus a turntable, etc. The mobile device 150 can drive the slave 100 to move and turn, thereby realizing multi-directional movement in the entire room. The control device can be specifically installed on or in the housing 110, and the user can send a signal to the control device by wireless transmission or infrared remote control, thereby controlling the movement of the mobile device 150. A program can also be written into the control mainboard to enable the slave 100 to move autonomously. It can be understood that the movement of the slave 100 can be controlled in real time by remote control, mobile phone APP remote control, etc., or the position, time, and movement path of the slave 100 can be preset. It is also possible to set an obstacle avoidance sensor such as an infrared sensor and an ultrasonic sensor on the slave 100 so that the slave 100 can autonomously avoid obstacles and turn to move, and the control device controls the slave 100 to have multiple action modes, so that the slave 100 is equivalent to an air-conditioning robot, which can adjust the moving direction according to the feedback of the indoor environment and autonomously plan the walking route, thereby ensuring that the slave 100 can avoid obstacles and walk flexibly. It is also possible to set up temperature, humidity or pollutant sensors so that the slave 100 can detect the environmental status of a certain area during its movement, so that it can independently determine whether to leave or stay to continue to supply air. Of course, it is also possible to set up a visual sensor on the slave 100, so that the slave 100 can move to shoot a panoramic image of the room, and upload it to the cloud system, so that the user can observe the movement of the slave 100200 at any time through smart devices such as mobile phones, tablets, and computers. Of course, the above control device can also be used to control the slave 100 to detach from the host 200.

[0078] Optionally, the control device includes a controller and a sensor for receiving a roadblock signal, and the controller is used to plan a walking route according to the roadblock signal of the sensor, and control the mobile device 150 to drive the sub-machine 100 to move.

[0079] Specifically, the sensor includes at least one of a laser sensor, a radar sensor, an infrared sensor, an ultrasonic sensor, an acoustic sensor, and a visual sensor. Specifically, the laser radar can be set at the top of the sub-machine 100, and the ultrasonic sensor can be set at the bottom of the housing 110, so that the detection range of the laser radar is wider, and the detection accuracy of the ultrasonic sensor is higher, so that the detection effect of the entire sub-machine 100 is better and the accuracy is higher. After the sub-machine 100 is separated from the accommodating cavity 211. The sensor scans and detects the environment in which the sub-machine 100 is located, so that it can understand the part of the entire room and plan the walking route autonomously. In the process of the movement of the sub-machine 100, the sensor also senses obstacles at a certain distance (such as furniture, steps, carpets, etc. that hinder the movement of the sub-machine 100), and after sensing the obstacle, the sub-machine 100 can perform operations such as retreating and turning, so that it can autonomously avoid obstacles, effectively avoid collisions, and plan the walking route in real time according to the room situation. In this way, it is ensured that the slave 100 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, thereby realizing the flexible walking of the slave 100 indoors.

[0080] Specifically, a temperature, humidity or pollutant sensor can also be set on the body of the sub-machine 100, so that the sub-machine 100 can detect the environmental status of a certain area during the movement, so that it can independently judge whether to leave or stay to continue to supply air. For example, when it is detected that the temperature in the area where many people gather is high, a certain area is dusty, and the humidity is high or low, the sub-machine 100 stays and continues to supply air, and selects the processing function of the air processing module according to the feedback situation to achieve the corresponding processing of air. 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 visual sensor can also be set on the sub-machine 100, and the sub-machine 100 can move to shoot a panoramic image of the room, and upload it to the cloud system, so that the user can observe the movement of the sub-machine 100 at any time through smart devices such as mobile phones, tablets, and computers. Compared with moving the entire floor-standing air-conditioning indoor unit 300, the sub-unit 100 can realize autonomous movement and independently plan the walking route according to the environment, making the movement of the sub-unit 100 more flexible and convenient, thereby being able to meet the different air treatment needs of users, with a high degree of intelligence and easy operation.
