In this way, when the sub-unit is separated from the main unit, it can supply cold air through the cold storage medium in the cold storage medium tank. The structure of the sub-unit is simple. Compared with semiconductor refrigeration, the refrigeration efficiency is high, the refrigeration effect is better, and when the sub-unit moves, it does not need to be connected to the outdoor unit through a refrigerant pipe to achieve mobile cold air supply, making the movement of the sub-unit unrestricted and capable of flexible and large-range air supply, thus meeting the user's demand for whole-house refrigeration.

[0046] The present invention provides a floor-standing air conditioner indoor unit.

[0047] In an embodiment of the present invention, as Figures 1 to 7 shown, the floor-standing air conditioner indoor unit includes a main unit 100 and a sub-unit 200. The main unit 100 includes an indoor heat exchange module 110 and a first docking module 120, and the first docking module 120 is used to connect to a heat exchange component 300. The heat exchange component 300 includes a compressor 310 and a first heat exchanger 320. The sub-unit 200 is detachably connected to the main unit 100. The sub-unit 200 includes a housing 210 and a second docking module 220 installed in the housing 210. The housing 210 is provided with an air inlet 211, an air outlet 212, and an air supply channel 213 connecting the air inlet 211 and the air outlet 212. The sub-unit 200 further includes a cold storage medium tank 230, a cold storage heat exchanger 240, and a sub-unit fan 250 installed in the air supply channel 213. When the sub-unit 200 is reset to the main unit 100, the second docking module 220 docks with the first docking module 120 so that the refrigerant pipes of the cold storage heat exchanger 240 and the first heat exchanger 320 are connected and communicated. The cold storage heat exchanger 240 is at least partially located in the cold storage medium tank 230 for cooling the cold storage medium in the cold storage medium tank 230. The sub-unit fan 250 is used to drive air to flow into the air supply channel 213 from the air inlet 211, and after directly or indirectly exchanging heat with the cold storage medium in the cold storage medium tank 230, it is blown out from the air outlet 212.

[0048] 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 usage requirements and is not limited herein. Optionally, the cross-section of the main unit 100 is circularly arranged. The main unit 100 and the sub-unit 200 extend in the up and down direction as a whole, and the main unit 100 and the sub-unit 200 can be arranged with equal cross-sections or variable cross-sections in the up and down direction.

[0049] A heat exchange air duct is provided inside the main unit 100, and the indoor heat exchange module 110 is installed in the heat exchange air duct. The indoor heat exchange module 110 is used to exchange heat with the air flowing through the heat exchange air duct to achieve refrigeration or heating. The indoor heat exchange module 110 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 communicated with the heat exchange air duct. An indoor heat exchanger and an indoor fan are provided in the heat exchange air duct. The indoor fan drives the air to enter the heat exchange air duct from the heat exchange air inlet, and blows out from the heat exchange air outlet after heat exchange through the indoor heat exchanger, so as to achieve indoor refrigeration or heating. Among them, the indoor heat exchange module 110 also includes structures such as refrigerant pipes and air guide louvers, and its specific structure can refer to the existing technology of floor-mounted air conditioner indoor units, which will not be elaborated here.

[0050] The slave unit 200 is detachably connected to the main unit 100. Then the slave unit 200 can be connected inside the main unit 100. For example, a receiving cavity 140 is provided inside the main unit 100 so that the slave unit 200 is installed in the receiving cavity 140. At this time, the receiving cavity 140 can be located at the upper, middle or lower part of the main unit 100. The slave unit 200 can also be spliced with the main unit 100. At this time, the slave unit 200 can be spliced at the lower end of the main unit 100, that is, the top of the slave unit 200 is connected to the bottom of the main unit 100. Then the main unit 100 can be hung on the wall, or the main unit 100 can be manually disassembled, so that the main unit 100 and the slave unit 200 are separated. The slave unit 200 can also be spliced above the main unit 100. At this time, the bottom of the slave unit 200 is connected to the top of the main unit 100. The slave unit 200 can also be spliced on the side of the main unit 100, so that the side wall surface of the slave unit 200 is connected to the side wall surface of the main unit 100. By splicing the slave unit 200 to the main unit 100, the volume and occupied space of the main unit 100 can be reduced. Specifically, the top of the slave unit 200 is spliced with the bottom of the main unit 100.

[0051] The connection between the slave unit 200 and the master unit 100 can be a structural connection, for example, connected by snap connection, magnetic attraction connection, plug connection, etc. It can be understood that the slave unit 200 can be separated from the master unit 100 by manual disassembly by the user, or the slave unit 200 can be actively separated from the master unit 100 by the control device without manual operation by the user. When the slave unit 200 is detached from the master unit 100, the slave unit 200 can move cyclically indoors autonomously to meet the air supply requirements of the entire indoor space and make the air supply in the entire space uniform. It can also be manually moved by the user to move the slave unit 200 to the required position indoors or make the slave unit 200 move autonomously to a certain position, such as an area where many people gather, so as to be able to meet the fixed-point air supply in a certain area, achieve long-distance, fixed-point, and directional air supply, and improve the air-conditioning heat exchange and air supply effect. Compared with moving the entire floor-standing air-conditioning indoor unit, the movement of the slave unit 200 is more flexible and convenient, thus being able to meet different usage requirements of users. Moreover, the slave unit 200 can perform relay air supply on the air flow blown out from the heat exchange air outlet of the master unit 100, making the air supply distance farther and the air supply range wider.

[0052] The first heat exchanger 320 can specifically be a plate heat exchanger. The heat exchange assembly 300 can be installed outdoors, indoors, or partially outdoors and partially indoors. It can be understood that the heat exchange assembly 300 includes a compressor 310 and a first heat exchanger 320. When the heat exchange assembly 300 is installed outdoors, the heat exchange assembly 300 can be the outdoor unit part of the entire floor-standing air conditioner, then the first heat exchanger 320 is an outdoor heat exchanger, and the first heat exchanger 320 is connected to the indoor heat exchange module 110 through a refrigerant pipe to meet the cooling and heating requirements of the indoor heat exchange module 110. The heat exchange assembly 300 can also be a separately provided heat exchange structure independent of the outdoor unit. When the heat exchange assembly 300 is installed indoors or partially indoors, the heat exchange assembly 300 is a heat exchange structure independent of the outdoor unit part of the floor-standing air conditioner. The heat exchange assembly 300 can specifically be installed on the master unit 100. The first docking module 120 is connected to the heat exchange assembly 300, specifically connected to the refrigerant pipe of the first heat exchanger 320 of the heat exchange assembly 300. Then the first docking module 120 can be multiple refrigerant pipe joints. The second docking module 220 is specifically provided on the outer wall surface protruding from the housing 210, and the inner end of the second docking module 220 is connected to the refrigerant pipe of the cold storage heat exchanger 240. Then the second docking module 220 can be multiple refrigerant pipe joints. When the slave unit 200 is repositioned on the master unit 100, the first docking module 120 and the second docking module 220 are hermetically docked, so that the refrigerant pipe of the first heat exchanger 320 of the heat exchange assembly 300 is hermetically connected to the refrigerant pipe of the cold storage heat exchanger 240. In this way, the cold storage heat exchanger 240 of the slave unit 200 can operate, and at this time, the slave unit 200 is equivalent to a mini air conditioner.

[0053] A cold storage medium tank 230 is provided in the air supply channel 213. The cold storage medium tank 230 can be a detachable structure from the housing 210 or a non-detachable structure. To facilitate the cleaning of the cold storage medium tank 230, the cold storage medium tank 230 is usually detachably connected to the housing 210. The cross-sectional shape of the cold storage medium tank 230 is adapted to the cross-sectional shape of the air supply channel 213. Cold storage medium is placed in the cold storage medium tank 230, and water, ice, eutectic salt, etc. can be used as the cold storage medium. When the second docking module 220 of the slave unit 200 is docked with the first docking module 120 of the first host unit 100, the cold storage heat exchanger 240 operates to achieve refrigeration. And the cold storage heat exchanger 240 is at least partially placed in the cold storage medium tank 230. Then the cold storage heat exchanger 240 is placed in the cold storage medium tank 230 to refrigerate the cold storage medium in the cold storage medium tank 230, so that the cold storage medium stores cold. In an embodiment, the cold storage medium tank 230 is a water tank, and the cold storage heat exchanger 240 is used to make ice from the water in the water tank. Then the cold storage effect is good and the cost is low. Thus, when the slave unit 200 is separated from the host unit 100 and the first docking module 210 is separated from the second docking module 220, the slave unit 200 can store cold through the cold storage medium.

[0054] The slave unit fan 250 can specifically be an axial flow fan, a centrifugal fan, etc., and can be selected and designed according to actual needs, and no specific limitation is made here. The slave unit fan 250 drives the air flow to flow into the air supply channel 213 from the air inlet 211, and blows out from the air outlet 212 after directly or indirectly exchanging heat with the cold storage medium in the cold storage medium tank 230. Then the heat of the air flow blown into the air supply channel 213 is absorbed by the cold storage medium, thereby reducing the air flow temperature. In this way, the air flow blown out from the air outlet 212 is a low-temperature air flow to achieve the effect of supplying cold air. It can be understood that when the air flow directly exchanges heat with the cold storage medium in the cold storage medium tank 230, the cold storage medium tank 230 is directly on the air supply flow path of the air supply channel 213. When the air flow indirectly exchanges heat with the cold storage medium in the cold storage medium tank 230, the cold quantity conversion of the cold storage medium can be carried out through other structures and media, which can improve the heat exchange effect and reduce the air resistance of the cold storage medium tank 230 to increase the overall air volume.

[0055] The floor-standing air conditioner indoor unit of the present invention is detachably connected to the main unit 100 through the slave unit 200, and enables the slave unit 200 to work independently away from the main unit 100. While ensuring rapid heat exchange throughout the room, the slave unit 200 can be separated from the main unit 100 to achieve 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 slave unit 200, so that the entire floor-standing air conditioner indoor unit has high flexibility and can meet the air supply requirements at different positions of users. Moreover, the slave unit 200 can relay the heat exchange air flow blown out by the main unit 100, so as to achieve long-distance and multi-directional air supply. At the same time, while enabling the floor-standing air conditioner indoor unit to supply air in multiple directions, over a long distance, and throughout the house, the slave unit 200 is connected to the main unit 100, thereby realizing the integration of multiple machines for storage, saving room space, and improving space utilization. In addition, the first docking module 120 of the main unit 100 is used to dock with the heat exchange component 300. When the slave unit 200 is reset to the main unit 100, the second docking module 220 of the slave unit 200 is docked with the first docking module 120 of the main unit 100, so that the cold storage heat exchanger 240 in the slave unit 200 is communicated with the refrigerant pipe of the heat exchange component 300, and at least part of the cold storage heat exchanger 240 is located in the cold storage medium tank 230 for refrigerating the cold storage medium in the cold storage medium tank 230. After the air flow is driven by the fan to directly or indirectly exchange heat with the cold storage medium in the cold storage medium tank 230, it is blown out to the room through the air outlet 212. In this way, when the slave unit 200 is separated from the main unit 100, it can supply cold air through the cold storage medium in the cold storage medium tank 230. The structure of the slave unit 200 is simple. Compared with semiconductor refrigeration, it has high refrigeration efficiency, better refrigeration effect, and can realize mobile cold air supply without being connected to the outdoor unit through a refrigerant pipe, so that the movement of the slave unit 200 is not restricted, and it can supply air flexibly and over a large range, thus meeting the needs of users for whole-house refrigeration.

[0056] In one embodiment, please refer to Figure 4 , Figure 6 and Figure 7 , the slave unit 200 further includes a heat exchange component 260 installed in the air supply channel 213. The heat exchange component 260 includes a pump body 261 and a heat exchange coil 262. Part of the heat exchange coil 262 is arranged in the cold storage medium tank 230, and the other part of the heat exchange coil 262 is arranged corresponding to the air outlet 212 and / or the air outlet 212. The pump body 261 is used to drive the heat exchange liquid in the heat exchange coil 262 to circulate.

[0057] In this embodiment, the pump body 261 may specifically be a circulating water pump. It can be understood that a heat exchange liquid is provided in the heat exchange coil 262, and the heat exchange liquid may specifically be water or an ethylene glycol aqueous solution, etc. Then, the heat exchange liquid in the heat exchange coil 262 is driven to circulate by the water pump. The heat exchange liquid in the heat exchange coil 262 located in the cold storage medium tank 230 exchanges heat with the cold storage medium, causing this part of the heat exchange liquid to rapidly cool down. The water pump drives the low-temperature heat exchange liquid to flow to the position corresponding to the air outlet 212 and / or the air inlet 211 of the heat exchange coil 262. Then, the sub-machine fan 250 directly drives the air flow to blow towards the heat exchange coil 262. After the air flow exchanges heat with the low-temperature heat exchange liquid in the heat exchange coil 262, it is rapidly cooled down, making the air flow blown out from the air outlet 212 a low-temperature air flow. The heat exchange liquid after heat exchange circulates and flows into the heat exchange coil 262 located in the cold storage medium tank 230 for heat exchange to achieve a refrigeration cycle. Of course, an induction device may also be provided in the sub-machine 200. When it senses that the temperature of the cold storage medium is higher than the preset temperature, a prompt sound or other prompt information may be set to remind the user to reset the sub-machine 200 to refrigerate the cold storage medium. Or the sub-machine 200 can be automatically reset to refrigerate the cold storage medium.

[0058] By providing the heat exchange coil 262, part of the heat exchange coil 262 is located in the circulating medium tank, and part of the heat exchange coil 262 is provided corresponding to the air inlet 211 and / or the air outlet 212. In this way, on the one hand, most or all of the air flow blown out from the air outlet 212 can be cooled and then blown out, improving the heat exchange efficiency and heat exchange effect. On the other hand, compared with directly exchanging heat between the air flow and the cold storage medium, the air flow path can be shortened, and the air resistance caused by the cold storage medium tank 230 can be avoided, thus greatly reducing the air resistance and improving the air supply volume and air supply effect.

[0059] Based on the above embodiment, further, the heat exchange component 260 includes a cold extraction heat exchanger 263 and a cold release heat exchanger 264. The cold extraction heat exchanger 263 is connected to the cold release heat exchanger 264 through the heat exchange coil 262. The cold extraction heat exchanger 263 is at least partially disposed in the cold storage medium tank 230, and the cold release heat exchanger 264 is provided corresponding to the air inlet 211 and / or the air outlet 212. By providing the cold extraction heat exchanger 263 and the cold release heat exchanger 264, the cold extraction heat exchanger 263 is connected to the cold release heat exchanger 264 through the heat exchange coil 262, making the structure of the entire heat exchange component 260 more compact and facilitating the installation of the heat exchange component 260. Placing the cold extraction heat exchanger 263 in the cold storage medium tank 230 and setting the cold release heat exchanger 264 corresponding to the air outlet 212 and / or the air inlet 211 can increase the heat exchange area of the heat exchange coil 262, thus greatly improving the heat exchange efficiency and making the refrigeration effect of the entire sub-machine 200 better, and even achieving the refrigeration effect of a mobile air conditioner.

[0060] Further, please refer to againFigure 4 , Figure 6 and Figure 7 , the cold storage medium tank 230 is installed at the lower part of the slave unit 200, the slave unit fan 250 and the cold release heat exchanger 264 are installed at the upper part of the slave unit 200 and are located above the cold storage medium tank 230, and the air inlet 211 is opened on the side wall of the housing 210.

[0061] In this embodiment, the air inlet 211 can be opened on the front side wall, left side wall, right side wall or rear side wall of the housing 210, and the air inlet 211 should correspond to the air inlet side of the slave unit fan 250. Since the slave unit fan 250 is installed at the upper part of the slave unit 200, the air inlet 211 is also opened on the upper side wall of the housing 210. By installing the cold storage medium tank 230 at the lower part of the slave unit 200 and the slave unit fan 250 and the cold release heat exchanger 264 at the upper part of the slave unit 200, when the slave unit fan 250 drives the air flow to flow through the air supply channel 213, the air flow basically does not flow through the cold storage medium tank 230, so that the air resistance of the cold storage medium tank 230 and the lower structure of the air supply channel 213 can be reduced, and the overall air supply volume of the slave unit 200 can be improved.

[0062] In one embodiment, as Figures 1 to 6 shown, the heat exchange component 300 is installed on the main unit 100 and is isolated from the indoor heat exchange module 110. The heat exchange component 300 can be installed inside the main unit 100 or outside the main unit 100. When the heat exchange component 300 is installed outside the main unit 100, the heat exchange component 300 can also be isolated from the main unit 100 and is only installed on the main unit 100 through the first docking module 120. By installing the heat exchange component 300 on the main unit 100 and isolating it from the indoor heat exchange module 110, that is, making the heat exchange component 300 independent of the outdoor unit of the floor-standing air conditioner, the refrigeration efficiency of the indoor heat exchange module 110 will not be affected.

[0063] Furthermore, please refer to Figures 1 to 4 , the main unit 100 includes a housing 131, the floor-standing air conditioner indoor unit further includes a sub-housing 132 provided outside the housing 131, the indoor heat exchange module 110 is installed inside the housing 131, the first docking module 120 is installed on the outer wall of the sub-housing 132 and is integrally or detachably connected to the housing 131. The sub-housing 132 has a heat dissipation inlet 10, a heat dissipation outlet 20 and a heat dissipation air duct 30 connecting the heat dissipation inlet 10 and the heat dissipation outlet 20. The heat exchange component 300 is installed in the heat dissipation air duct 30, and the heat dissipation outlet 20 is communicated with the outside.

[0064] In this embodiment, the heat dissipation outlet 20 can be communicated with the outside through an exhaust duct. The cross-sectional shape of the sub-shell 132 can be rectangular or circular, etc. The sub-shell 132 is installed outside the housing 131 through the first docking module 120. Then, the sub-shell 132 can be connected to the housing 131. The sub-shell 132 and the housing 131 can be integrally formed or detachably connected. It is also possible to arrange the sub-shell 132 and the housing 131 at intervals. At this time, the heat dissipation inlet 10 can be opened on the side wall surface of the sub-shell 132 close to the housing 131. In a specific embodiment, the sub-shell 132 and the housing 131 are detachably connected through the first docking module 120. In this way, the first docking module 120 and the heat exchange component 300 can be detached from the host 100 for maintenance and replacement, and can be directly detached when not in use. By installing the heat exchange component 300 in the heat dissipation air duct 30 of the sub-shell 132, the heat of the heat exchange component 300 can be discharged to the outside through the heat dissipation outlet 20, avoiding heat from entering the room and affecting the indoor temperature. The heat dissipation inlet 10 can be communicated with the inside of the room or the outside of the room.

[0065] Specifically, as Figure 3 , Figure 4 , Figure 6 and Figure 9 shown, the heat exchange component 300 further includes a heat dissipation fan 330. The heat dissipation fan 330 is used to drive air flow to enter from the heat dissipation inlet 10, flow through the first heat exchanger 320 and then blow out through the heat dissipation outlet 20. The first docking module 120 is isolated from the heat dissipation air duct 30 and is communicated with the refrigerant pipe of the first heat exchanger 320. The heat dissipation fan 330 drives the air flow to dissipate heat from the first heat exchanger 320, and then discharges it to the outside through the heat dissipation outlet 20. The heat dissipation fan 330 can specifically be a centrifugal fan or an axial flow fan. The arrangement of the heat dissipation fan 330, the compressor 310, and the first heat exchanger 320 can be designed and selected according to the shape of the sub-shell 132. In a specific embodiment, the compressor 310 and the first heat exchanger 320 are located at the lower part of the heat dissipation air duct 30, and the fan is located above the compressor 310. By isolating the first docking module 120 from the heat dissipation air duct 30, it is possible to prevent the hot air flow in the heat dissipation air duct 30 from overflowing into the room through the first docking module 120 and affecting the indoor temperature.

[0066] In one embodiment, please refer to Figure 3 and Figure 4 , a receiving cavity 140 is defined inside the host 100. At least a part of the first docking module 120 extends into the receiving cavity 140, and at least a part of the sub-machine 200 is installed in the receiving cavity 140 so that the second docking module 220 is docked with the first docking module 120.

[0067] 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 sub-machine 200, that is, when in the non-working state, the sub-machine 200 is completely accommodated in the accommodation cavity 140. Of course, part of the sub-machine 200 can also be located inside the accommodation cavity 140 and part outside the accommodation cavity 140, that is, 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. By arranging at least part of the sub-machine 200 in the accommodation cavity 140 of the host 100, compared with the overall splicing of the sub-machine 200 and the host 100, it is easier to maintain the overall consistency after the two are connected, thereby improving the user experience.

[0068] The sub-machine 200 can be detachably installed in the accommodation cavity 140. Then, the sub-machine 200 can be directly placed in the accommodation cavity 140 and separated from the accommodation cavity 140 by means of rolling, sliding, etc. The sub-machine 200 can also be installed in the accommodation cavity 140 by means of 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 of the sub-machine 200 being installed in the accommodation cavity 140 and being taken out of the accommodation cavity 140, which will not be listed one by one here. The user can manually move the sub-machine 200 out of the accommodation cavity 140, so that the sub-machine 200 is separated from the host 100. It can also be controlled for the sub-machine 200 to move out of the host 100 autonomously. At this time, the accommodation cavity 140 needs to be arranged at the bottom of the host 100 so that the sub-machine 200 can move out of the accommodation cavity 140 autonomously.

[0069] When the heat exchange component 300 is installed outside the host 100, since the first docking module 120 needs to be connected to the first heat exchanger 320, the first docking module 120 can be directly extended from the outside of the housing 131 into the accommodation cavity 140. Of course, when the heat exchange component 300 is located inside the host 100, it can specifically be located inside the accommodation cavity 140 or at a position inside the host 100 avoiding the accommodation cavity 140, as long as at least part of the first docking module 120 extends into the accommodation cavity 140. In this way, when the sub-machine 200 is reset and moved to the host 100, the second docking module 220 on the sub-machine 200 can be directly docked with the first docking module 120 to realize the refrigeration of the cold storage medium in the sub-machine 200.

[0070] In one embodiment, as Figure 2 、 Figures 4 to 8 shown, the sub-machine 200 further includes a control device and a moving device 270. The moving device 270 is installed at the bottom of the housing 210, and the control device is used to control the moving device 270 to drive the sub-machine 200 to move.

[0071] In this embodiment, the mobile device 270 can specifically be in the form of a driving wheel plus a caster wheel, a roller plus a turntable, etc. Thus, the mobile device 270 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 specifically be installed on or inside the housing 210 of the slave unit 200. Then, the user can send signals to the control device by means of wireless transmission or infrared remote control, etc., and further control the movement of the mobile device 270. A program can also be written into the control main board so that the slave unit 200 moves autonomously. It can be understood that the movement of the slave unit 200 can be controlled in real time by means of remote control with a remote control, remote control with a mobile phone APP, 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, etc. can also be set, 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 judge whether to leave or stay to continue blowing air. Whether the slave unit 200 can continue to refrigerate can also be judged through the induction device. If the refrigeration capacity is insufficient, the slave unit 200 can be controlled to reset and store cold for the cold storage medium. Of course, a vision sensor can also be set on the slave unit 200. The slave unit 200 moves to capture 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.

[0072] In one embodiment, the host 100 extends along the up-and-down direction, the accommodation cavity 140 is located at the lower part of the host 100, and an installation opening 141 communicating with the accommodation cavity 140 is provided on the side wall of the host 100, so that the control device controls the mobile device 270 to drive the slave unit 200 to enter and detach from the accommodation cavity 140 through the installation opening 141.

[0073] In this embodiment, to facilitate the separation of the slave unit 200 from the accommodation cavity 140, the shape of the installation opening 141 is adapted to the vertical cross-sectional shape of the slave unit 200. The installation opening 141 should be larger than the maximum vertical cross-section of the slave unit 200, so that the slave unit 200 can be detached from the accommodation cavity 140 through the installation opening 141. To enable the slave unit 200 to smoothly enter and exit the accommodation cavity 140, the bottom of the accommodation cavity 140 should be formed by the bottom plate of the host 100. Thus, the height of the bottom of the accommodation cavity 140 is the thickness of the bottom plate of the host 100, which is usually 0.6 - 1 mm, enabling the slave unit 200 to smoothly enter and exit the accommodation cavity 140 autonomously. By enabling the control device to control the moving device 270 to drive the body of the slave unit 200 to enter and exit the accommodation cavity 140 through the installation opening 141, the slave unit 200 can achieve autonomous movement and detachment from the accommodation cavity 140 without manual movement, making the slave unit 200 highly automated and more intelligent, thereby enhancing the user experience.

[0074] Further, please refer to Figure 1 and Figure 2 , the host 100 further includes a switch door 150, and the switch door 150 is coverably and opening / closingly arranged to cover the installation opening 141.

[0075] In this embodiment, the switch door 150 can be a single-leaf door or a double-leaf door, which can be selected and designed according to actual needs. The switch door 150 is coverably and opening / closingly arranged to cover the installation opening 141. When the slave unit 200 needs to be detached from the host 100 and enter the room to work independently, only need to open the switch door 150, and the slave unit 200 can move out autonomously and perform functions such as moving air supply, purification, humidification, dehumidification, and sterilization in the house, with high automation and simple and convenient operation. When the slave unit 200 is not needed, the switch door 150 is closed, hiding the slave unit 200 inside the host 100, thus ensuring the overall consistency of the machine and effectively preventing dust from entering the accommodation cavity 140. In other embodiments, the switch door 150 may not be provided, and the installation opening 141 is arranged as an open mouth, so that the slave unit 200 can be moved out or into the accommodation cavity 140 at any time.

[0076] In one embodiment, the switch door 150 is detachably connected to the host 100 to open or close the installation opening 141. Then the switch door 150 can be installed on the host 100 by means of snap connection, magnetic connection, suction cup connection, groove rail connection, etc. The switch door 150 is detachably connected to the host 100, with a simple structure, easy to implement, and low production cost.

[0077] In another embodiment, the switch door 150 is rotatably connected to the main body 100 to open or close the installation opening 141. Specifically, the switch door 150 rotates circumferentially along the main body 100 to open the installation opening 141. The switch door 150 can be hinged to the main body 100 and the installation opening 141 is opened by the way of outward opening the door. The switch door 150 can also be rotated to open through an arc-shaped guide rail or an arc-shaped rack. By rotating to open the switch door 150, the opening method is simple, fast and easy to implement. The switch door 150 can be manually rotated to open or close the installation opening 141, or the switch door 150 can be rotated by a driving device to open or close the installation opening 141. In yet another embodiment, the switch door 150 is provided as a rolling shutter door. Thus, the switch door 150 is wound up and down or laterally wound to open the installation opening 141.

[0078] In some embodiments, the switch door 150 is slidably connected to the main body 100 to open or close the installation opening 141. Specifically, the switch door 150 slides up and down along the main body 100 to open the main body 100. The up-and-down sliding opening of the switch door 150 to open the installation opening 141 can be realized by setting a chute slide rail, a rack structure extending in the up-and-down direction, etc. By sliding up and down to open the switch door 150, the opening method is simple, fast and easy to implement. The switch door 150 can be manually slid to open or close the installation opening 141, or the switch door 150 can be slid by a driving device to open or close the installation opening 141. In one embodiment, the switch door 150 is provided as a retractable door. Thus, the switch door 150 is retracted in the up-and-down direction, left-and-right direction or circumferential direction of the main body 100 to open or close the installation opening 141.

[0079] Furthermore, the main body 100 further includes a driving device, which is connected to the switch door 150 to drive the switch door 150 to rotate or slide to open the installation opening 141; the floor-standing air-conditioning indoor unit further includes an electric control box and a sensing device electrically connected to the electric control box. The electric control box is installed on the main body 100 and is used to control the driving device to drive the switch door 150 to open after receiving the start signal of the slave unit 200;

[0080] The electric control box is further used to control the driving device to drive the switch door 150 to close when the sensing device senses that the slave unit 200 is reset in the accommodation cavity 140 and / or the slave unit 200 exits the accommodation cavity 140.

[0081] In this embodiment, the driving device may specifically be structures such as a driving motor or a driving cylinder. The driving shaft of the driving motor can be directly connected to the switch door 150, or indirectly connected to the switch door 150 through a transmission structure such as a gear rack, etc., to drive the switch door 150 to rotate and open. The driving shaft of the driving device drives the switch door 150 to slide open through structures such as a gear rack. By setting the driving device to drive the switch door 150 to open, the door body is automatically opened, with a high degree of intelligence and a good user experience.

[0082] The slave unit 200 can be powered on through methods such as a power-on button, infrared remote control, mobile phone APP, autonomous startup, etc., and transmit the power-on signal to the power-on sensor of the induction device, and the power-on sensor sends the power-on signal to the electronic control box. Then when the electronic control box receives the power-on signal of the slave unit 200, it controls the driving device to drive the switch door 150 to open. In one embodiment, the induction device includes a signal receiver and a signal generator. The signal generator is installed on the body of the slave unit 200, and the signal receiver is installed on the master unit 100. The signal receiver is used to emit a signal to open the switch door 150 to the electronic control box when it senses through the signal generator that the slave unit 200 moves outside the master unit 100 and approaches the master unit 100. The signal generator can be a sensor capable of transmitting distance information such as an infrared sensor, a laser sensor, a vision sensor, an ultrasonic sensor, etc. Then when the signal receiver receives the transmission signal of the signal generator and determines the distance between the two, if the slave unit 200 moves towards the master unit 100 and the distance between the two is less than or equal to the preset approaching distance, it means that the slave unit 200 needs to perform a reset movement. At this time, the signal receiver sends a signal to open the switch door 150 to the electronic control box, and the electronic control box controls the driving device to drive the switch door 150 to open. In this way, the automatic opening of the switch door 150 is realized, so that the reset of the slave unit 200 is fully automated, without manual operation, with a high degree of intelligence, simple and convenient operation, and precise control. In other embodiments, a signal generator can also be set on the master unit 100 and a signal receiver can be set on the slave unit 200 to move the slave unit 200 to a position close to the switch door 150. Of course, it is also possible to make the signal generator capable of both emitting and receiving signals, and the signal receiver capable of both emitting and receiving signals.

[0083] It can be understood that a limiting structure and a reset sensor can be arranged in the accommodation cavity 140. When the slave unit 200 cooperates with the limiting structure and is reset, the reset sensor is triggered. The reset sensor sends a signal to the electric control box to close the switch door 150, so that the electric control box controls the driving device to drive the switch door 150 to close. When the sensing device senses that the slave unit 200 is separated from the accommodation cavity 140, it controls the driving device to drive the switch door 150 to close. When the slave unit 200 moves indoors, the switch door 150 is closed, making the overall consistency of the main unit 100 good. The automatic opening and closing of the switch door 150 are realized through the sensing device, with intelligent control, high automation, simple and convenient operation, and precise control.

[0084] Specifically, the sensing device further includes a body sensor. The body sensor is used to send a signal to the electric control box to close the switch door 150 when it senses that the slave unit 200 is separated from the accommodation cavity 140. The body sensor can specifically be a timing sensor, a distance sensor, etc. When the body sensor determines that the slave unit 200 is separated from the accommodation cavity 140 through parameters such as time and distance, it sends a signal to the electric control box to close the switch door 150. Thus, when the slave unit 200 works away from the main unit 100, the switch door 150 can be automatically closed to ensure the overall consistency of the main unit 100. In another embodiment, the signal receiver is also used to send a signal to the electric control box to close the switch door 150 when it senses that the slave unit 200 is far away from the main unit 100 through the signal generator. In this way, when the signal receiver receives that the slave unit 200 is far away from the main unit 100, that is, when the distance between the two is greater than or equal to the preset far-away distance, it sends a signal to the electric control box to close the switch door 150. The electric control box controls the switch door 150 to close. In this way, the signal receiver can be directly used without additionally arranging a body sensor, simplifying the overall control system.

[0085] In one embodiment, as Figures 1 to 4 shown, an air outlet duct 160 and a fresh air outlet 161 communicating with the air outlet duct 160 are formed in the main unit 100. The floor-standing air conditioner indoor unit further includes an air guide duct 400 and a fresh air fan 500 installed in the air guide duct 400. The air guide duct 400 is located outside the main unit 100 and communicates with the outside and the air outlet duct 160 respectively.

[0086] In this embodiment, specifically, the air outlet duct 160 is located between the accommodation cavity 140 and the heat exchange duct. The air outlet duct 160 and the heat exchange duct of the main unit 100 can be communicated with each other or isolated from each other. In fact, the heat exchange duct and the air outlet duct 160 are arranged to be isolated from each other. In this way, the heat exchange duct and the air outlet duct 160 are independent of each other and do not affect each other. And when the slave unit 200 is installed in the accommodation cavity 140, the heat exchange duct is isolated from the air supply channel 213 of the slave unit 200. In this way, the heat exchange duct and the air supply channel 213 are independent of each other and do not affect each other, so that when the slave unit 200 enters and exits the accommodation cavity 140, it will not affect the heat exchange effect of the indoor heat exchange module 110, ensuring the heat exchange stability of the entire floor-standing air conditioner indoor unit.

[0087] By arranging the air duct 400 outside the main unit 100 and connecting it to the air outlet duct 160, and arranging the fresh air fan 500 in the air duct 400. The fresh air fan 500 is installed outside the main unit 100, without additionally occupying the space inside the main unit 100, thereby improving the space utilization rate of the whole housing 131 and 210. And compared with installing the fresh air fan 500 in the wall, the circuit can be shortened, the wiring is more convenient and fast, and at the same time, corresponding holes are avoided being drilled on the wall, reducing the installation process. Specifically, the fresh air device further includes a purification component arranged in the air duct 400. The purification component can specifically be a HEPA net.

[0088] On the basis of the above embodiment, further, please refer to Figure 3 and Figure 4 , the accommodation cavity 140 is located below the air outlet duct 160. The air outlet duct 160 and the accommodation cavity 140 are connected through a gas communication port 180. The main unit 100 further includes a first valve 171, and the first valve 171 is installed at the gas communication port 180 to block or conduct the air outlet duct 160 and the accommodation cavity 140. The air outlet 212 is opened at the top of the housing 210 and is arranged corresponding to the gas communication port 180.

[0089] In this embodiment, the first valve 171 can be rotated to open the gas communication port 180 or slid to open the gas communication port 180. The first valve 171 can specifically be a plate-like structure or a louver structure, etc. By making the air outlet duct 160 communicate with the accommodation cavity 140 through the gas communication port 180 and arranging the first valve 171 at the gas communication port 180, when the slave unit 200 is installed in the accommodation cavity 140, the first valve 171 can be opened, so that the slave unit 200 can continuously refrigerate, and the air flow can be blown out from the air outlet 212 into the air outlet duct 160 and then blown out from the fresh air outlet 161 into the room. Thus, when the slave unit 200 is reset and the switch door 150 closes the installation opening 141, the slave unit 200 can still achieve heat exchange and air supply. Thereby enabling the upper and lower parts of the entire floor-standing air conditioner indoor unit to achieve refrigeration, greatly improving the refrigeration effect. In addition, when the slave unit 200 is reset to the main unit 100 and the first docking module 120 and the second docking module 220 are continuously docked, the slave unit 200 can also achieve the heating function. In order to improve the air outlet efficiency, the air outlet 212 of the slave unit 200 is made to be docked with the gas communication port 180.

[0090] Furthermore, the main unit 100 further includes a second valve 172. In the air inlet direction of the air induction pipe 400, the second valve 172 is located upstream of the first valve 171, and the second valve 172 is used to block or conduct the outdoor air flow from flowing into the air outlet duct 160. The second valve 172 can be rotated to open or slid to open. The second valve 172 can specifically be a plate-like structure or a louver structure, etc. The second valve 172 can specifically be installed at the fresh air inlet of the air induction pipe 400, or installed inside the air induction pipe 400, or installed at the connection between the air induction pipe 400 and the machine shell 131. Of course, the second valve 172 can also be arranged inside the air outlet duct 160, as long as the second valve 172 is located upstream of the first valve 171 and can block or conduct the outdoor air flow from flowing into the air outlet duct 160. Thus, by setting the second valve 172, it is possible to prevent the fresh air from entering the air outlet duct 160 from the outside when the fresh air is not needed, affecting the air outlet effect. Usually, the first valve 171 and the second valve 172 are selectively opened. That is, when the first valve 171 is opened, that is, when the slave unit 200 needs to blow air through the air outlet duct 160 in the accommodation cavity 140, the second valve 172 blocks the outdoor air flow from flowing into the air outlet duct 160. When the first valve 171 is closed and fresh air needs to be introduced, the second valve 172 is opened and the fresh air fan 500 is started.

[0091] In a preferred embodiment, such as Figure 3 and Figure 4As shown, the fresh air blower 500 includes a first axial flow impeller 510 and a second axial flow impeller 520. The air supply directions of the first axial flow impeller 510 and the second axial flow impeller 520 are the same, and the rotation directions are opposite.
