[0023] A valve plate, arranged on the top rod and located on the inner side of the base facing the inside of the water storage tank;

[0024] The push rod is configured to abut against the limiting protrusion on the second humidifying device and move upward so that the valve plate opens the through hole during the process of the water tank switching from the first state to the second state, and to move downward under the action of its own gravity and water pressure so that the valve plate blocks the water replenishment through hole during the process of the water tank switching from the second state to the first state.

When the water storage tank is in the first state, it is located in the humidifying air duct, and can provide a water source for the first humidifying device, so that it is convenient to use the air conditioner indoor unit to humidify the indoor environment space; when the water storage tank is in the second state, it is located in the cavity, and can replenish water for the second humidifying device of the sweeping robot, so that the second humidifying device is used to humidify the indoor environment space after the sweeping robot leaves the cavity. It can be seen that the present invention can provide humidification water for both the first humidifying device of the air conditioner indoor unit and the second humidifying device of the sweeping robot through the special design of the water storage tank, thereby realizing the sharing of the humidification water storage tank.

[0039] Based on the following detailed description of specific embodiments of the present invention in conjunction with the accompanying drawings, those skilled in the art will become more aware of the above and other objects, advantages and features of the present invention.

The same reference numerals in the accompanying drawings indicate the same or similar components or parts.

[0045] The present invention first provides an air conditioner indoor unit. Figure 1 and Figure 2 1 is a schematic structural diagram of an air conditioner indoor unit in different states according to an embodiment of the present invention. Figure 1 and Figure 2 The figure also shows a sweeping robot 2. Figure 1 and Figure 2 The air conditioner indoor unit 1 of the present invention includes a casing 10, a first humidifying device 20 and a water storage tank 30 for storing humidification water.

[0046] A humidification air duct 11 and a cavity 12 located at the lower end of the housing 10 are formed in the housing 10, and the cavity 12 is used to accommodate the sweeping robot 2 entering the housing 10. That is, the cavity 12 provides an accommodating space for the sweeping robot 2.

[0047] The first humidifying device 20 is used to humidify the airflow flowing in the humidifying air duct 11. The humidified airflow is sent into the indoor environment space where the air-conditioning indoor unit 1 is located, and the humidity in the indoor environment space can be increased.

[0048] The water storage tank 30 is configured to be movably disposed in the housing 10 and has a first state in which it is in the humidification air duct 11 to provide a water source for the first humidification device 20 (see Figure 1 ), and a second state in which the second humidifying device 201 of the sweeping robot 2 is replenished with water in the cavity 12 (see Figure 2 Embodiment shown).

[0049] The air conditioner indoor unit 1 provided by the present invention comprises a housing 10, a first humidifying device 20 and a water storage tank 30, and the first humidifying device 20 can be used to humidify the airflow flowing in the humidifying air duct 11 in the housing 10, thereby achieving the purpose of humidifying the indoor environment space. In particular, the lower end of the housing 10 is also formed with a cavity 12 for accommodating a sweeping robot, and a movable water storage tank 30 is also provided in the housing 10. When the water storage tank 30 is in a first state, it is located in the humidifying air duct 11, and can provide a water source for the first humidifying device 20, so as to facilitate the use of the air conditioner indoor unit 1 to humidify the indoor environment space; when the water storage tank 30 is in a second state, it is located in the cavity 12, and can replenish water for the second humidifying device 201 of the sweeping robot 2, so that the second humidifying device 201 can be used to humidify the indoor environment space after the sweeping robot 2 leaves the cavity 12.

[0050] It can be seen that the present invention can provide humidification water for both the first humidification device 20 of the air-conditioning indoor unit 1 and the second humidification device 201 of the sweeping robot 2 through the special design of the water tank 30 , thereby realizing the sharing of the humidification water tank 30 .

[0051] The present invention breaks through the traditional design concept that the water tank 30 is fixed in the existing design. In particular, the water tank 30 is arranged to be movable. The state switching of the water tank 30 is realized through the movement of the water tank 30, thereby realizing the function switching of the water tank 30 to supply water to the first humidifying device 20 or to replenish water to the second humidifying device 201, eliminating the complicated water supply pipeline, simplifying the structure of the air-conditioning indoor unit 1, and achieving many beneficial technical effects that surpass the existing technology.

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

[0053] It is understandable that, in order to facilitate the robot vacuum cleaner to enter and exit the cavity 12, the cavity 12 must be located at the lower end of the housing 10. In order to facilitate the humidified airflow to be more evenly distributed in the indoor environment space, the humidified airflow of the air conditioner indoor unit preferably has a certain blowing height. Therefore, the humidified air duct 11 should not be arranged at the lower end of the housing 10, but above the cavity 12.

[0054] Based on the positional relationship between the humidification air duct 11 and the cavity 12 and the state requirements of the water storage tank 30, the water storage tank 30 is configured to move in the up-down direction in the housing 10, so as to provide humidification water for the first humidification device 20 when it moves upward to the first state in the humidification air duct 11, and to replenish water for the second humidification device 201 when it moves downward to the second state in the cavity 12. That is, the water storage tank 30 only needs to move up and down in a straight line to realize the mutual switching between its 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 includes a water tank driving device 40, which is used to drive the water tank 30 to move up and down in a controlled manner, so as to automatically adjust the state of the water tank 30 through the water tank driving device 40, thereby facilitating intelligent control.

[0056] Specifically, the water tank driving device 40 is used to controllably drive the water tank 30 to move linearly in the up and down directions, so as to simplify the structure of the water tank driving device 40 .

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

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

[0059] The first gear transmission mechanism 42 is used to transmit the driving force generated by the first driving motor 41 to the rack 43, so that the rack 43 drives the water tank 30 to move up and down.

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

[0061] Specifically, the first driving motor 41 and the first gear transmission mechanism 42 may be disposed inside the housing 10 and outside the water tank 30 .

[0062] In some embodiments, a water replenishment port 31 is provided at the bottom of the water storage tank 30, and a water replenishment switch 32 is provided at the water replenishment port 31. The water replenishment switch 32 is configured to open the water replenishment port 31 when the water storage tank 30 is in the second state to allow the water in the water storage tank 30 to flow out through the water replenishment port 31 to the second humidification device 201 of the sweeping robot 2, and to block the water replenishment port 31 after the water storage tank 30 moves upward from the second state to prevent the water in the water storage tank 30 from flowing out through the water replenishment port 31.

[0063] It should be noted that the water replenishment switch 32 may be a mechanical switch to open or block the water replenishment port 31 through the interaction of mechanical structures. The water replenishment switch 32 may also be an electrically controlled switch to open or block the water replenishment port 31 in a controlled manner.

[0064] Figure 3 yes Figure 2 Schematic enlarged view of part A in FIG. In some embodiments, Figure 3 The water replenishment switch 32 may specifically include a base 321 , a top rod 322 and a valve plate 323 .

[0065] The base 321 is disposed at the bottom of the water storage tank 30 and covers the water replenishment port 31, and a through hole 324 is opened in the middle of the base 321. Specifically, the base 321 can be located inside the water storage tank 30 to cover the water replenishment port 31 from the inner side of the water replenishment port 31. At this time, the base 321 can be tightly fitted with the inner bottom wall of the water storage tank 30 located around the water replenishment port 31 to prevent the water in the water storage tank 30 from leaking through the matching 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 located outside the water storage tank 30 to cover the water replenishment port 31 from the outer side of the water replenishment port 31. At this time, the base 321 can be tightly fitted with the outer bottom wall of the water storage tank 30 located around the water replenishment port 31 to prevent the water in the water storage tank 30 from leaking through the matching 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 disposed 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 tank 30 to flow through the gap.

[0067] The valve plate 323 is disposed on the top rod 322 and is located on 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 when the water tank 30 is switched from the first state to the second state so that the valve plate 323 opens the through hole 324, and to move downward under the action of its own gravity and the pressure of water when the water tank 30 is switched from the second state to the first state so that the valve plate 323 blocks the through hole 324.

[0069] When the water tank 30 switches from the first state to the second state, the lower end of the push rod 322 abuts against the limit protrusion 202 on the second humidifying device 201. As the water tank 30 continues to move downward, the base 321 continues to move downward with the water tank 30, and the push rod 322 stops moving downward due to the abutment of the limit protrusion 202. The push rod 322 is gradually lifted by the limit protrusion 202, and the valve plate 323 on the push rod 322 is gradually separated from the base 321, thereby opening the through hole 324. The water in the water tank 30 flows to the second humidifying device 201 through the through hole 324 and the water replenishment port 31 in turn, achieving the purpose of replenishing water for the second humidifying device 201.

[0070] When the water tank 30 switches from the second state to the first state, the lower end of the push rod 322 gradually separates from the limiting protrusion 202, and the upward pushing pressure on the push rod 322 from the limiting protrusion 202 disappears. Under the action of the gravity of the push rod 322 and the pressure of the water in the water tank 30 on the push rod 322 and the valve plate 323, the push rod 322 moves downward relative to the water tank 30 until the valve plate 323 fits against the base 321, thereby blocking the through hole 324 on the base 321 and preventing the water in the water tank 30 from continuing to flow out.

[0071] Specifically, the base 321 may be provided with a convex edge 325 that is located around the through hole 324 and protrudes upward to form a sealing ring effect. The diameter of the valve plate 323 is larger than the diameter of the convex edge 325. When the water storage tank 30 is in the first state, the valve plate 323 is tightly abutted against the convex edge 325, thereby improving the sealing effect between the valve plate 323 and the base 321.

[0072] In some embodiments, the first humidification device 20 includes a humidification drum 21, which is configured to rotate in a controlled manner in the water tank 30 when the water tank 30 is in a first state, and to bring out the water in the water tank 30 when it rotates, thereby using the brought out water to humidify the airflow flowing through the humidification drum 21 in the humidification air duct 11.

[0073] Furthermore, the top of the water storage tank 30 is open, and when the airflow in the humidification air duct 11 flows through the humidification drum 21 rotating in the water storage tank 30, it will contact the water brought out by the humidification drum 21, and the flowing airflow will take away part of the water, and the humidity will increase, forming a humidified airflow. In addition, the flowing airflow may contain impurities such as dust. When the airflow contacts the water, the impurities such as dust are at least partially dissolved in the water, and the water not taken away by the airflow returns to the water storage tank 30 again, achieving the purpose of airflow purification.

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

[0075] It is understandable that the humidifying drum 21 may move synchronously with the water storage tank 30 , or may not move with the water storage tank 30 .

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

[0077] The second drive motor 22 is fixedly disposed in the housing 10. That is, the second drive motor 22 will not move with the movement of the water storage tank 30, so as to facilitate the arrangement of the electrical connection wires and avoid the electrical connection wires being in a disorderly manner.

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

[0079] The humidifying drum 21 is arranged inside the water tank 30 and moves synchronously with the water tank 30, so that the humidifying drum 21 is transmission-connected with the second gear transmission mechanism 23 when the water tank 30 moves to its first state, and the humidifying drum 21 is separated from the second gear transmission mechanism 23 when the water tank 30 moves to its second state.

[0080] Specifically, the humidifying drum 21 is rotatably supported inside the water storage tank 30, and the wall of the water storage tank 30 provides support for the humidifying drum 21, so the humidifying drum 21 can move synchronously with the movement of the water storage tank 30. When the water storage tank 30 moves to its first state, the humidifying drum 21 is connected to the second gear transmission mechanism 23, and the driving force of the second driving motor 22 is transmitted to the humidifying drum 21 through the second gear transmission mechanism 23, thereby driving the humidifying drum 21 to rotate. When the water storage tank 30 moves to its second state, the humidifying drum 21 is separated from the second gear transmission mechanism 23, and the humidifying drum 21 no longer rotates due to the lack of driving force.

[0081] In some alternative embodiments, the humidifying drum 21 may not move synchronously with the water tank 30. In this case, the humidifying drum 21 may be supported by a supporting structure outside the water tank 30. When the water tank 30 moves to its first state, the humidifying drum 21 is accommodated therein. At this time, the second drive motor 22 is started to drive the humidifying drum 21 to rotate, and the water in the water tank 30 can be brought out. When the water tank 30 moves to its second state, the humidifying drum 21 is outside the water tank 30. Even if the humidifying drum 21 rotates, it will not bring out the water in the water tank 30 and will not play any humidification role. Therefore, the second drive motor 22 is not started at this time.

[0082] Figure 4 1 is a schematic structural diagram of an air conditioner indoor unit in another state according to an embodiment of the present invention. In some embodiments, an entrance 13 for the sweeping robot 2 to enter and exit the cavity 12 is provided at the lower end of the housing 10. A guide plate 14 is provided at the entrance 13, and the guide plate 14 is pivotally connected to the housing 10 to controllably block the entrance 13 or open the entrance 13.

[0083] Furthermore, the pivot shaft 15 between the guide plate 14 and the housing 10 is located at the bottom of the entrance 13, that is, the guide plate 14 pivots up and down about its pivot shaft, and the bottom of the guide plate 14 when it is in a state of blocking the entrance 13 forms a fixed end connected to the pivot shaft 15, and the top of the guide plate 14 when it is in a state of blocking the entrance 13 forms a movable pivot end. The height of the pivot shaft 15 is higher than the height of the bottom of the housing 10, so that when the guide plate 14 opens the entrance 13, the guide plate 14 is tilted and supported on the ground, so that the sweeping robot 2 can enter and exit the cavity 12 along the guide plate 14.

[0084] That is, the present invention reasonably designs the opening and closing method of the guide plate 14, so that the guide plate 14 not only forms a cover for opening or blocking the entrance and exit 13, but also can guide the sweeping robot 2 to smoothly pass through the entrance and exit 13 in and out of the casing 10 when it opens the entrance and exit 13, thereby playing a better guiding role.

[0085] The present invention also provides an indoor environment adjustment system 100. Figure 5 1 is a schematic structural block diagram of an indoor environment adjustment system according to an embodiment of the present invention. The indoor environment adjustment system 100 includes a sweeping robot 2 and an air-conditioning indoor unit 1 described in any of the above embodiments.

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

[0087] The air conditioner indoor unit 1 includes a housing 10, a first humidifying device 20 and a water storage tank 30 for storing humidification water. A humidification air duct 11 and a cavity 12 located at the lower end of the housing 10 are formed in the housing 10, and the cavity 12 is used to accommodate the sweeping robot 2 entering the housing 10. That is, the cavity 12 provides an accommodating space for the sweeping robot 2.

[0088] The water storage tank 30 is configured to be movably disposed in the housing 10 and has a first state in which it is in the humidification air duct 11 to provide a water source for the first humidification device 20 (see Figure 1 ), and a second state in which the second humidifying device 201 of the sweeping robot 2 is replenished with water in the cavity 12 (see Figure 2 Embodiment shown).

[0089] The present invention can provide humidification water for both the first humidification device 20 of the air-conditioning indoor unit 1 and the second humidification device 201 of the sweeping robot 2 through the special design of the water storage tank 30 , thereby realizing the sharing of the humidification water storage tank 30 .

[0090] Specifically, the second humidifying device 201 may include a humidifying water tank 203 and an atomizer 204 fluidly connected to the humidifying water tank 203 , so as to utilize the atomizing chamber 204 to atomize the water in the humidifying water tank 203 into water mist to humidify the air.

[0091] Furthermore, the limiting protrusion 202 is arranged at the bottom of the humidification water tank 203 and protrudes and extends upward.

[0092] Furthermore, a positioning portion 205 is provided at the bottom of the humidifying water tank 203, and the positioning portion 205 is used to cooperate with the water tank 30 when the water tank 30 is in the second state to limit the relative movement of the water tank 30 and the humidifying water tank 203. The combination of the limiting protrusion 202 and the positioning portion 205 can limit the water tank 30 more firmly.

[0093] In the description of the present embodiment, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.
