[0045] The present application provides an air conditioner indoor unit, Figure 1 Figure 2 are schematic structural diagrams of an air conditioner indoor unit in different states according to an embodiment of the present application. For the convenience of understanding, Figure 1 Figure 2 The floor cleaning robot 2 is also shown in FIGS. 1A and 1B. Referring to Figure 1 Figure 2 The air conditioner indoor unit 1 of the present application comprises a casing 10, a first humidifying device 20 and a water storage tank 30 for storing water for humidification.

[0046] The casing 10 is formed with a humidifying air duct 11 and a cavity 12 at the lower end of the casing 10, the cavity 12 being used for accommodating the floor cleaning robot 2 entering the casing 10. That is, the cavity 12 provides accommodation space for the floor cleaning robot 2.

[0047] The first humidifying device 20 is used for humidifying the airflow circulating in the humidifying air duct 11. The humidified airflow is sent into the indoor environment space where the air conditioner indoor unit 1 is located, so as to increase the humidity in the indoor environment space.

[0048] The water storage tank 30 is movably arranged in the casing 10 and has a first state (see the embodiment shown in FIG. 1A) in which the water storage tank 30 is located in the humidifying air duct 11 to provide water source for the first humidifying device 20, and a second state (see the embodiment shown in FIG. 1B) in which the water storage tank 30 is located in the cavity 12 to replenish the second humidifying device 201 of the floor cleaning robot 2. Figure 1 Figure 2 The water storage tank 30 is movably arranged in the casing 10 and has a first state (see the embodiment shown in FIG. 1A) in which the water storage tank 30 is located in the humidifying air duct 11 to provide water source for the first humidifying device 20, and a second state (see the embodiment shown in FIG. 1B) in which the water storage tank 30 is located in the cavity 12 to replenish the second humidifying device 201 of the floor cleaning robot 2.

[0049] The air conditioner indoor unit 1 of the present application comprises the casing 10, the first humidifying device 20 and the water storage tank 30, can utilize the first humidifying device 20 to humidify the airflow circulating in the humidifying air duct 11 in the casing 10, and further achieve the purpose of humidifying the indoor environment space. In particular, the lower end of the casing 10 is further formed with the cavity 12 for accommodating the floor cleaning robot, and the water storage tank 30 movably arranged in the casing 10 is located in the humidifying air duct 11 in the first state to provide water source for the first humidifying device 20, so as to facilitate the humidification of the indoor environment space by the air conditioner indoor unit 1; the water storage tank 30 is located in the cavity 12 in the second state to replenish the second humidifying device 201 of the floor cleaning robot 2, so as to utilize the second humidifying device 201 to humidify the indoor environment space after the floor cleaning robot 2 leaves the cavity 12.

[0050] It can be seen that the present application can provide humidification water for both the first humidifying device 20 of the air conditioner indoor unit 1 and the second humidifying device 201 of the floor cleaning robot 2 by the special design of the water storage tank 30, and realizes the sharing of the humidification water storage tank 30. ​​​​

[0051] The present application breaks through the traditional design concept that the water storage tank 30 is fixed in the prior art design, and in particular, the water storage tank 30 is arranged to be movable, the state switching of the water storage tank 30 is realized by the movement of the water storage tank 30, and then the function switching of the water storage tank 30 for supplying water to the first humidifying device 20 or for supplementing water to the second humidifying device 201 is realized, the complex water conveying pipeline is saved, the structure of the air conditioner indoor unit 1 is simplified, and many beneficial technical effects beyond the prior art are achieved.

[0052] In some embodiments, the humidifying air duct 11 is located above the cavity 12.

[0053] It can be understood that, in order to facilitate the sweeping robot to enter and exit the cavity 12, the cavity 12 must be at the lower end of the shell 10. In order to facilitate the humidified air flow to be more uniformly distributed in the indoor environment space, the humidified air flow of the air conditioner indoor unit preferably has a certain blowing height, and therefore the humidifying air duct 11 is not suitable to be arranged at the lower end of the shell 10, but is located above the cavity 12.

[0054] Based on the positional relationship between the humidifying air duct 11 and the cavity 12 and the state requirement of the water storage tank 30, the water storage tank 30 is configured to move in the shell 10 in the up-down direction to provide humidifying water for the first humidifying device 20 when moving upward to the first state in the humidifying air duct 11 and to supplement water for the second humidifying device 201 when moving downward to the second state in the cavity 12. That is, the water storage tank 30 only needs to move linearly in the up-down direction to realize the mutual switching between the first state and the second state, and the movement mode is simple and easy to realize.

[0055] In some embodiments, the air conditioner indoor unit 1 further comprises a water tank driving device 40, and the water tank driving device 40 is used to drive the water storage tank 30 to move up and down under control, so as to automatically adjust the state of the water storage tank 30 through the water tank driving device 40 and facilitate intelligent control.

[0056] Specifically, the water tank driving device 40 is used to drive the water storage tank 30 to move linearly in the up-down direction under control, so as to simplify the structure of the water tank driving device 40.

[0057] In some embodiments, the water tank driving device 40 comprises a first driving motor 41, a first gear transmission mechanism 42 and a rack 43 which are sequentially transmissionally connected.

[0058] The rack 43 is formed on the outer side wall of the water storage tank 30 or fixedly connected with the water storage tank 30 to move synchronously with the water storage tank 30. Moreover, the rack 43 extends in the up-down direction to drive the water storage tank 30 to move up and down when the rack 43 translates up and down.

[0059] The first gear transmission mechanism 42 is configured to transmit the driving force generated by the first driving motor 41 to the rack 43 to drive the rack 43 to move the water storage tank 30 up and down.

[0060] Specifically, the first gear transmission mechanism 42 can include at least one gear.

[0061] Specifically, the first driving motor 41 and the first gear transmission mechanism 42 can be arranged inside the casing 10 and outside the water storage tank 30.

[0062] In some embodiments, the bottom of the water storage tank 30 is provided with a water replenishment opening 31, and the water replenishment opening 31 is provided with a water replenishment switch 32. The water replenishment switch 32 is configured to open the water replenishment opening 31 to allow the water in the water storage tank 30 to flow out of the water replenishment opening 31 to the second humidifying device 201 of the robotic vacuum cleaner 2 when the water storage tank 30 is in the second state, and to block the water replenishment opening 31 to prevent the water in the water storage tank 30 from flowing out of the water replenishment opening 31 after the water storage tank 30 moves upward from the second state.

[0063] It should be noted that the water replenishment switch 32 can be a mechanical switch to open or block the water replenishment opening 31 through the interaction of mechanical structures. The water replenishment switch 32 can also be an electrically controlled switch to open or block the water replenishment opening 31 under control.

[0064] Figure 3 is Figure 2 is a schematic enlarged view of part A. In some embodiments, as shown in Figure 3 Specifically, the water replenishment switch 32 can include a base 321, a top rod 322, and a valve piece 323.

[0065] The base 321 is arranged at the bottom of the water storage tank 30 and covers the water replenishment opening 31, and the middle part of the base 321 is provided with a through hole 324. Specifically, the base 321 can be arranged inside the water storage tank 30 to cover the water replenishment opening 31 from the inner side of the water replenishment opening 31. At this time, the base 321 can be tightly fitted with the inner bottom wall of the water storage tank 30 around the water replenishment opening 31 to prevent the water in the water storage tank 30 from leaking through the cooperation interface between the base 321 and the inner bottom wall of the water storage tank 30. In other embodiments, the base 321 can also be arranged outside the water storage tank 30 to cover the water replenishment opening 31 from the outer side of the water replenishment opening 31. At this time, the base 321 can be tightly fitted with the outer bottom wall of the water storage tank 30 around the water replenishment opening 31 to prevent the water in the water storage tank 30 from leaking through the cooperation interface between the base 321 and the outer bottom wall of the water storage tank 30.

[0066] The top rod 322 is configured to be movably arranged in the through hole 324 in the up-down direction. It can be understood that a gap is formed between the top rod 322 and the hole wall of the through hole 324, which not only allows the top rod 322 to move smoothly along the through hole 324, but also allows the water in the water storage tank 30 to flow through the gap.

[0067] The valve piece 323 is arranged on the top rod 322 and located at the inner side of the base 321 facing the inside of the water storage tank 30.

[0068] The top rod 322 is configured to abut against the limiting protrusion 202 on the second humidifying device 201 and move upward to make the valve piece 323 open the through hole 324 during the process that the water storage tank 30 is switched from the first state to the second state, and move downward under the action of gravity and water pressure to make the valve piece 323 block the through hole 324 during the process that the water storage tank 30 is switched from the second state to the first state.

[0069] During the process that the water storage tank 30 is switched from the first state to the second state, the lower end of the top rod 322 abuts against the limiting protrusion 202 on the second humidifying device 201. As the water storage tank 30 continues to move downward, the base 321 continues to move downward with the water storage tank 30, while the top rod 322 stops moving downward due to the abutting action of the limiting protrusion 202, the top rod 322 is gradually lifted by the limiting protrusion 202, and the valve piece 323 on the top rod 322 gradually separates from the base 321, thereby opening the through hole 324. The water in the water storage tank 30 flows to the second humidifying device 201 through the through hole 324 and the water replenishing port 31 in turn, achieving the purpose of replenishing water for the second humidifying device 201.

[0070] During the process that the water storage tank 30 is switched from the second state to the first state, the lower end of the top rod 322 gradually separates from the limiting protrusion 202, and the upward pressure of the limiting protrusion 202 on the top rod 322 disappears. Under the action of gravity of the top rod 322 and the pressure of the water in the water storage tank 30 on the top rod 322 and the valve piece 323, the top rod 322 moves downward relative to the water storage tank 30 until the valve piece 323 is in close contact with the base 321, thereby blocking the through hole 324 on the base 321 and preventing the water in the water storage tank 30 from continuing to flow out.

[0071] Specifically, the base 321 can be provided with a ring of raised edges 325 around the through hole 324 and protruding upward to form a sealing ring effect. The diameter of the valve piece 323 is greater than the diameter of the raised edges 325. When the water storage tank 30 is in the first state, the valve piece 323 abuts against the raised edges 325 tightly, improving the sealing effect between the valve piece 323 and the base 321.

[0072] In some embodiments, the first humidifying device 20 includes a humidifying roller 21 configured to rotate in the water storage tank 30 under control when the water storage tank 30 is in the first state, and to bring out water in the water storage tank 30 when it rotates, thereby using the brought-out water to humidify the airflow flowing through the humidifying roller 21 in the humidifying air duct 11.

[0073] Further, the top of the water storage tank 30 is open, and when the airflow in the humidifying air duct 11 flows through the rotating humidifying roller 21 in the water storage tank 30, the airflow contacts the water carried by the humidifying roller 21, and the flowing airflow carries away part of the water, increases the humidity, and forms a humidified airflow. In addition, the flowing airflow may contain dust and other impurities, and when the airflow contacts the water, the dust and other impurities are at least partially dissolved in the water, and the water that is not carried away by the airflow returns to the water storage tank 30, achieving the purpose of airflow purification.

[0074] For the first humidifying device 20 using a roller to humidify, the humidifying roller 21 does not have water storage capacity, therefore, the water storage tank 30 not only provides a water source for humidification, but the water storage tank 30 itself also forms an indispensable part of the first humidifying device 20 to achieve the humidification function. That is, when the first humidifying device 20 is used to humidify the airflow in the humidifying air duct 11, the water storage tank 30 must be in the first state located in the humidifying air duct 11.

[0075] It can be understood that the humidifying roller 21 can move synchronously with the water storage tank 30, or can not move with the water storage tank 30.

[0076] In some embodiments, the first humidifying device 20 further comprises a second driving motor 22 and a second gear transmission mechanism 23.

[0077] The second driving motor 22 is fixedly arranged in the cabinet 10. That is, the second driving motor 22 will not move with the movement of the water storage tank 30, so as to arrange the electric connection line and avoid the electric connection line being messy.

[0078] The second gear transmission mechanism 23 is in transmission connection with the second driving motor 22, for transmitting the driving force generated by the second driving motor 22. The second gear transmission mechanism 23 and the second driving motor 22 always maintain a transmission connection relationship, therefore, the second gear transmission mechanism 23 will not move with the movement of the water storage tank 30.

[0079] The humidifying roller 21 is arranged in the interior of the water storage tank 30, and moves synchronously with the water storage tank 30, so that the humidifying roller 21 is in transmission connection with the second gear transmission mechanism 23 when the water storage tank 30 moves to its first state, and the humidifying roller 21 is separated from the second gear transmission mechanism 23 when the water storage tank 30 moves to its second state.

[0080] Specifically, the humidifying roller 21 is rotatably supported inside the water storage tank 30, and is supported by the tank wall of the water storage tank 30, so that the humidifying roller 21 can move synchronously with the water storage tank 30. When the water storage tank 30 moves to its first state, the humidifying roller 21 is in transmission connection with the second gear transmission mechanism 23, and the driving force transmitted by the second driving motor 22 is transmitted to the humidifying roller 21 through the second gear transmission mechanism 23, so as to drive the humidifying roller 21 to rotate. When the water storage tank 30 moves to its second state, the humidifying roller 21 is separated from the second gear transmission mechanism 23, and the humidifying roller 21 no longer rotates due to the lack of driving force.

[0081] In some alternative embodiments, the humidifying roller 21 can also not move synchronously with the water storage tank 30. At this time, the humidifying roller 21 can be supported by a support structure outside the water storage tank 30. When the water storage tank 30 moves to its first state, the humidifying roller 21 is accommodated therein, and when the second driving motor 22 is started to drive the humidifying roller 21 to rotate, the water in the water storage tank 30 can be brought out. When the water storage tank 30 moves to its second state, the humidifying roller 21 is outside the water storage tank 30, and even if the humidifying roller 21 rotates, the water in the water storage tank 30 will not be brought out, and will not play any humidifying role. Therefore, at this time, the second driving motor 22 is not started.

[0082] Figure 4 is a schematic structural view of the air conditioner indoor unit in another state according to an embodiment of the present application. In some embodiments, the lower end of the cabinet 10 is provided with an access opening 13 for the cleaning robot 2 to enter and exit the cavity 12. The access opening 13 is provided with a guide plate 14, which is pivotably connected with the cabinet 10 to controllably block or open the access opening 13.

[0083] Further, the pivot shaft 15 between the guide plate 14 and the cabinet 10 is located at the bottom of the access opening 13, that is, the guide plate 14 is pivoted up and down about the pivot shaft 15, the bottom of the guide plate 14 in the state of blocking the access opening 13 forms a fixed end connected with the pivot shaft 15, and the top of the guide plate 14 in the state of blocking the access opening 13 forms a movable pivoting end. The height of the pivot shaft 15 is higher than the height of the bottom of the cabinet 10, so that the guide plate 14 is obliquely supported on the ground when the guide plate 14 opens the access opening 13, thereby allowing the cleaning robot 2 to enter and exit the cavity 12 along the guide plate 14.

[0084] That is, the present application reasonably designs the opening and closing mode of the guide plate 14, so that the guide plate 14 not only forms a cover plate for opening or blocking the access opening 13, but also can guide the cleaning robot 2 to smoothly pass through the access opening 13 to enter and exit the cabinet 10 when the guide plate 14 opens the access opening 13, thereby playing a better guiding role.

[0085] The present application also provides an indoor environment adjusting system 100,Figure 5 is a schematic structural block diagram of an indoor environment conditioning system according to an embodiment of the present application, the indoor environment conditioning system 100 comprising a floor cleaning robot 2 and the air conditioner indoor unit 1 described in any of the above embodiments.

[0086] The floor cleaning robot 2 has a second humidifying device 201 for humidifying air.

[0087] The air conditioner indoor unit 1 comprises a casing 10, a first humidifying device 20 and a water storage tank 30 for storing water for humidification. The casing 10 is formed with a humidifying air duct 11 and a cavity 12 at a lower end of the casing 10, the cavity 12 being configured to accommodate the floor cleaning robot 2 entering the casing 10. That is, the cavity 12 provides an accommodation space for the floor cleaning robot 2.

[0088] The water storage tank 30 is configured to be movably arranged in the casing 10 and has a first state (see the embodiment shown in Figure 1 ) in which the water storage tank 30 is located in the humidifying air duct 11 to provide water source for the first humidifying device 20, and a second state (see the embodiment shown in Figure 2 ) in which the water storage tank 30 is located in the cavity 12 to replenish the second humidifying device 201 of the floor cleaning robot 2.

[0089] The present application realizes sharing of the water storage tank 30 for humidification by specially designing the water storage tank 30 to provide water for humidification for both the first humidifying device 20 of the air conditioner indoor unit 1 and the second humidifying device 201 of the floor cleaning robot 2.

[0090] Specifically, the second humidifying device 201 can comprise a humidifying water tank 203 and an atomizer 204 fluidly connected to the humidifying water tank 203, so as to atomize water in the humidifying water tank 203 into water mist by the atomizer 204 to humidify air.

[0091] Further, a limiting protrusion 202 is arranged at a bottom of the humidifying water tank 203 and extends upwardly and protrudingly.

[0092] Further, the bottom of the humidifying water tank 203 is further provided with a positioning portion 205 configured to cooperate with the water storage tank 30 when the water storage tank 30 is in the second state, so as to limit relative movement between the water storage tank 30 and the humidifying water tank 203. The limiting protrusion 202 and the positioning portion 205 in combination can more firmly limit the water storage tank 30.
