[0002] In order to meet the needs of people to improve the living environment, at present, a new type of air conditioner is configured with a water tank, and clean water is stored in the water tank. When the air conditioner starts the water washing function, the air flows through the water tank to remove water-soluble harmful substances, particulate matter, lint, dust and the like in the air, thereby purifying the air in the living environment, making the air in the environment warm and humid. During the process of the air conditioner performing the fresh air function, the clean water in the water tank will gradually decrease. In order to ensure the water washing function of the air conditioner, clean water needs to be supplemented into the water tank at any time.

[0046] As Figures 1 to 4As shown, the present embodiment provides an air conditioner indoor unit 1, which comprises a casing 100 and a fresh air device. The fresh air device comprises an air inlet assembly 200, a water adding assembly 300 and a pipeline assembly 400. In the present embodiment, the air conditioner indoor unit 1 is a cabinet type air conditioner indoor unit 1. The air inlet assembly 200 is arranged in the casing 100. The air inlet assembly 200 comprises a water storage portion 210. The water storage portion 210 is configured to purify and humidify the fluid flowing through the air inlet assembly 200. The water adding assembly 300 extends out of the casing 100. The water adding assembly 300 is arranged above the water storage portion 210. The water adding assembly 300 is configured to add water to the water storage portion 210. The upper end 430 of the pipeline assembly 400 is in communication with the water adding assembly 300. The lower end 440 of the pipeline assembly 400 is in communication with the water storage portion 210. The pipeline assembly 400 is configured to be controlled to be opened to allow the water adding assembly 300 to add water to the water storage portion 210 through the pipeline assembly 400 or closed to prevent the water adding assembly 300 from adding water to the water storage portion 210 through the pipeline assembly 400.

[0047] The casing 100 is configured to carry or accommodate the components in the air conditioner indoor unit 1. The shape, size and material of the casing 100 are not limited. As shown, Figures 1 to 2 The main body of the casing 100 is cuboid. Obviously, this shape is only exemplary and not the only one.

[0048] The air inlet assembly 200 is configured to supply air to the air conditioner indoor unit 1. In the present embodiment, the air inlet assembly 200 comprises at least the water storage portion 210 to purify and humidify the air flowing through the water storage portion 210. The other components of the air inlet assembly 200 are not limited as long as they can be used to supply air to the air conditioner indoor unit 1. The specific arrangement of the air inlet assembly 200 in the casing 100 is not limited and can be selected as required. As shown, Figure 1 and Figure 2 The air inlet assembly 200 is arranged below the air conditioner indoor unit 1. Obviously, this is only exemplary and not the only one.

[0049] The water storage portion 210 can be a structure in the air inlet assembly 200 or an independent water tank. In the present embodiment, the water storage portion 210 is an independent water tank. The water storage portion 210 stores water for purifying and humidifying the air. The air in the air inlet assembly 200 is purified and humidified when flowing through the water storage portion 210.

[0050] The specific components of the water adding assembly 300 are not limited, and the water adding assembly 300 at least has an opening in communication with the upper end 430 of the pipe assembly 400, through which water is added into the pipe assembly 400 and flows into the water storage portion 210. In the embodiment, the water adding assembly 300 extends out of the casing 100, and the user can add water into the water storage portion 210 through the water adding assembly 300 without pulling the water storage portion 210 out of the casing 100. This not only facilitates operation, but also avoids affecting the performance of the air conditioner indoor unit 1 due to repeated pulling out of the water storage portion 210.

[0051] The water adding assembly 300 is located above the water storage portion 210, and "above" is understood in a broad sense, for example, can be directly above or obliquely above. The water adding assembly 300 is located above the water storage portion 210, so that the water in the water adding assembly 300 automatically flows into the water storage portion 210 under the action of gravity.

[0052] The pipe assembly 400 is configured to be controlled to open or close, and the specific manner in which the pipe assembly 400 is opened and closed is not limited. For example, the pipe assembly 400 includes a pipe 410 and a solenoid valve 420, and the solenoid valve 420 is configured to control the opening and closing of the pipe 410. For example, the pipe assembly 400 includes a pipe 410 and a movable cover plate, and the cover plate is configured to be controlled to move away from the pipe 410 or cover the hollow portion of the pipe 410. The specific manner in which the solenoid valve 420 and the cover plate are controlled is not limited, for example, the water storage portion 210 can be provided with a water level sensor, and the pipe assembly 400 can be controlled to open or close according to the lowest water level and the highest water level set in the predetermined program. For example, the user can set the lowest water level and the highest water level of the water storage portion 210.

[0053] In summary, the pipe assembly 400 of the air conditioner indoor unit 1 is configured to be controlled to open or close, which can ensure that the water level in the water storage portion 210 is between the lowest water level and the highest water level, and also avoid water overflow in the water storage portion 210 due to excessive water addition. At the same time, the water adding assembly 300 extends out of the casing 100, and the user adds water from the outside of the air conditioner indoor unit 1, which facilitates operation and avoids repeatedly pulling out the water storage portion 210 from the casing 100, thereby affecting the performance of the air conditioner indoor unit 1. The water adding assembly 300 extends out of the casing 100, so even if water overflows, it will overflow to the outside of the air conditioner indoor unit 1, avoiding affecting the performance of the air conditioner indoor unit 1 due to the overflow of water.

[0054] In other embodiments, the water adding assembly 300 includes a water adding portion 310, and the water adding portion 310 has a water adding groove 311, and the specific shape of the water adding portion 310 is not limited. As a specific embodiment, as shown in FIG. 4, the water adding portion 310 has a water adding groove 311, and the water adding groove 311 is in communication with the opening of the water adding assembly 300. Figure 6As shown, the main body of the water adding part 310 is in a plate shape, and a water injection groove 311 is formed in the center of the plate-shaped water adding part 310. The water adding part 310 is clamped to the outer side of the casing 100, and the specific clamping manner of the water adding part 310 can be selected as required. In the present embodiment, the water injection groove 311 is located in the casing 100, and the water adding part 310 is arranged on the outer side of the casing 100. The water adding part 310 with such a structure can further prevent the water overflowing from the water adding assembly 300 from flowing into the air conditioner indoor unit 1.

[0055] The bottom wall of the water injection groove 311 is provided with a water injection hole 312, and the upper end 430 of the pipeline assembly is in communication with the water adding assembly 300 through the water injection hole 312. The opening of the water adding assembly 300 is the water injection hole 312 on the water injection groove 311, and the shape of the water injection hole 312 can be selected as required, for example, it can be circular, square or other irregular shapes. The opening area of the water injection groove 311 is much larger than the opening area of the water injection hole 312, which makes it convenient for the user to add water to the water injection groove 311 and avoid spilling. The water injection hole 312 can avoid the water pressure in the pipeline assembly 400 being too large due to excessive water flow, avoid the water overflowing outward at the interface between the pipeline assembly 400 and the water adding assembly 300 or the air inlet assembly 200, and also avoid the water overflowing from the water storage part 210 due to excessive water flow.

[0056] In other embodiments, the water adding assembly 300 further comprises a water receiving part 320, the water receiving part 320 has a water receiving groove 321, the water receiving groove 321 is located directly below the water injection groove 311, the volume of the water receiving groove 321 is greater than the volume of the water injection groove 311, and the bottom wall of the water receiving groove 321 is provided with a connecting port 322, and the upper end 430 of the pipeline assembly is in communication with the water adding assembly 300 through the connecting port 322. The specific shape and arrangement position of the water receiving part 320 are not limited, and the water receiving groove 321 is formed on the water receiving part 320, and the water receiving groove 321 is located directly below the water injection groove 311. If the amount of water in the water storage part 210 does not reach the requirement, the pipeline 410 is controlled to be opened to continue adding water, and when the water receiving groove 321 is observed through the water injection hole 312, there is no water accumulation in the water receiving groove 321. If the amount of water in the water storage part 210 reaches the requirement, the pipeline 410 is controlled to be closed to continue adding water, and when the water receiving groove 321 is observed through the water injection hole 312, there is water accumulation in the water receiving groove 321. Such a structure can allow the user to intuitively determine whether the water storage part 210 reaches the maximum water level, thereby avoiding the water overflowing from the water receiving groove 321 and the water injection groove 311. Alternatively, the volume of the water receiving groove 321 is greater than the volume of the water injection groove 311, which can further avoid the water overflowing from the water receiving groove 321 and the water injection groove 311.

[0057] In some other embodiments, the opening area of the connecting port 322 is larger than the opening area of the water injection hole 312, and the bottom wall of the water receiving groove 321 is inclined to form the connecting port 322 at the lowest position. The opening area of the connecting port 322 being larger than the opening area of the water injection hole 312 can ensure that the water in the connecting groove flows to the pipeline assembly 400 as soon as possible, thereby improving the accuracy of determining whether the water storage part 210 reaches the maximum water level according to whether there is water in the water receiving groove 321, and improving the accuracy of determining whether the pipeline assembly 400 is closed. The bottom wall of the water receiving groove 321 is inclined to form the connecting port 322 at the lowest position, so that the connecting port 322 is located at the lowest part of the water receiving groove 321, and the water in the water receiving groove 321 automatically and quickly flows to the connecting port 322, further improving the accuracy of determining whether the water storage part 210 reaches the maximum water level according to whether there is water in the water receiving groove 321, and improving the accuracy of determining whether the pipeline assembly 400 is closed.

[0058] In some other embodiments, the water adding assembly 300 further comprises a receiving part 330 for receiving the condensed water generated by the evaporator in the air conditioner indoor unit 1, the receiving part 330 has a discharge port 331 for discharging the condensed water out of the air conditioner indoor unit 1, and the receiving part 330 is arranged in the water receiving part 320. The side wall of the water receiving groove 321 is formed with a gap 323 for overflowing the overflow water in the water receiving groove 321, and the receiving part 330 is used to guide the overflow water to the discharge port 331 and discharge it from the discharge port 331. Generally, the air conditioner indoor unit 1 is provided with a receiving part 330 for receiving and discharging the condensed water generated by the evaporator in the air conditioner indoor unit 1. In this embodiment, the inventors ingeniously integrate the receiving part 330 and the water receiving part 320, and use the receiving part 330 to discharge the overflow water in the water receiving groove 321, further avoiding the overflow of the water receiving groove 321 into the air conditioner indoor unit 1.

[0059] In some other embodiments, the pipeline assembly 400 comprises a pipeline 410 and an electromagnetic valve 420, the upper end of the pipeline 410 is in communication with the water adding assembly 300, and the lower end of the pipeline 410 is in communication with the water storage part 210. The electromagnetic valve 420 is arranged on the pipeline 410, and the electromagnetic valve 420 is configured to controllably open or close the pipeline 410.

[0060] In some other embodiments, the air inlet assembly 200 further comprises an air duct body 220 arranged above the water storage part 210, and the air duct body 220 is arranged below the water adding assembly 300, and a water washing air duct 222 is formed between the air duct body 220 and the water storage part 210. The lower end 440 of the pipeline assembly communicates with the water storage part 210 through the air outlet of the water washing air duct 222; wherein the water storage part 210 can be pushed and pulled relative to the air duct body 220 to be pushed out of the cabinet 100.

[0061] After the air passes through the water storage part 210, the water-soluble harmful substances, particulate matters, lint, dust and the like in the air are left in the water in the water storage part 210. Therefore, the water storage part 210 needs to be cleaned regularly, and in the present embodiment, the water storage part 210 can be pushed out of the casing 100 to facilitate cleaning.

[0062] Therefore, if the lower end 440 of the duct assembly directly communicates with the water storage part 210, when the water storage part 210 is pushed out of the casing 100, the water storage part 210 cannot be pushed out of the casing 100 due to the structural interference between the lower end 440 of the duct assembly and the water storage part 210. The lower end 440 of the duct assembly needs to be detached from the water storage part 210, so that the water storage part 210 can be detached from the air conditioner for cleaning. This not only makes the detachment of the water storage part 210 more troublesome, but also frequent detachment between the water storage part 210 and the lower end 440 of the duct assembly can cause water leakage at the contact between the lower end 440 of the duct assembly and the water storage part 210.

[0063] In the present embodiment, the air duct body 220 is arranged above the water storage part 210 and below the water adding assembly 300, i.e., the water adding assembly 300, the air duct body 220 and the water storage part 210 are arranged in sequence from top to bottom, and the water washing air duct 222 formed between the air duct body 220 and the water storage part 210 and the air outlet communicate with the water storage part 210. Therefore, the inventor ingeniously makes the water storage part 210 communicate with the lower end 440 of the duct assembly through the air outlet to supplement water to the water storage part 210, avoids direct connection between the lower end 440 of the duct assembly and the water storage part 210, and makes the water storage part 210 freely pulled out of the casing 100, avoiding the limitation of structural interference of the lower end of the duct assembly 400.

[0064] In other embodiments, the air duct body 220 further has a fresh air duct 221 above the water washing air duct 222, the top wall of the air duct body 220 has a first fresh air outlet 223 and a second fresh air outlet 224 arranged side by side, the fresh air duct 221 communicates with the first fresh air outlet 223, the water washing air duct 222 communicates with the second fresh air outlet 224, and the lower end 440 of the duct assembly communicates with the water storage part 210 through the second fresh air outlet 224. The second fresh air outlet 224 is formed on the top wall of the air duct body 220, which makes the water adding assembly 300, the duct assembly 400, the second fresh air outlet 224 and the water storage part 210 arranged from top to bottom, and the water in the water adding assembly 300 can automatically flow into the water storage part 210 under the action of gravity.

[0065] In some other embodiments, the air inlet assembly 200 further comprises an outlet baffle 230, which is pivotally arranged at the boundary between the first fresh air outlet 223 and the second fresh air outlet 224, and is turned towards the first fresh air outlet 223 to open the second fresh air outlet 224 and close the first fresh air outlet 223, and is turned towards the second fresh air outlet 224 to open the first fresh air outlet 223 and close the second fresh air outlet 224. The volute 240 is arranged on the top wall of the air duct body 220 and below the water adding assembly 300, and communicates with the first fresh air outlet 223 and the second fresh air outlet 224. The lower end 440 of the duct assembly is fixed on the volute 240, and is located directly above the second fresh air outlet 224 to communicate with the second fresh air outlet 224.

[0066] In the present embodiment, the air duct body 220 has the fresh air duct 221 and the water washing duct 222 arranged from top to bottom, and the air flow directions in the fresh air duct 221 and the water washing duct 222 are close to each other, and the air flow in the fresh air duct 221 and the water washing duct 222 can be simultaneously promoted by the air blower in the volute 240. Meanwhile, in order to meet the variety of air inlet of the air conditioner indoor unit 1, the outlet baffle 230 is arranged at the boundary between the first fresh air outlet 223 and the second fresh air outlet 224. As shown in Figure 9 the outlet baffle 230 is turned to be perpendicular to the boundary, the air conditioner indoor unit 1 simultaneously performs the fresh air function and the water washing function. When the outlet baffle 230 is turned to cover the first fresh air outlet 223, the air conditioner indoor unit 1 performs the water washing function. When the outlet baffle 230 is turned to cover the second fresh air outlet 224, the air conditioner indoor unit 1 performs the fresh air function. Moreover, the outlet baffle 230 can adjust the proportion of the fresh air and the water washing air, for example, when the outlet baffle 230 is turned to be inclined to the first fresh air outlet 223, the proportion of the water washing air is larger and the proportion of the fresh air is smaller. Similarly, when the outlet baffle 230 is turned to be inclined to the second fresh air outlet 224, the proportion of the fresh air is larger and the proportion of the water washing air is smaller. The inventor ingeniously makes the air conditioner have multiple different functions by using one outlet baffle 230.

[0067] In order to avoid the structural interference between the outlet baffle 230 and the lower end of the duct 410 when the outlet baffle 230 is turned, and to avoid the influence on the turning of the outlet baffle 230 and the influence on the water supplement of the duct 410 to the water storage part 210, in the present embodiment, the lower end 440 of the duct assembly is fixed on the volute 240, and the lower end 440 of the duct assembly is located above the second fresh air outlet 224, that is, the duct assembly 400 communicates with the second fresh air outlet 224 through the volute 240. In this way, the air conditioner can have multiple functions at the same time, and the structural interference between the outlet baffle 230 and the lower end of the duct assembly 400 can be avoided.

[0068] In some other embodiments, as shown in Figure 9 andFigure 10 As shown, the side wall of the duct assembly 400 has a fresh air inlet 225 in communication with the fresh air duct 221, through which outdoor fresh air enters the fresh air duct. The water washing duct has a water washing inlet 226 in communication with the fresh air duct, and an inlet baffle 250 is arranged at the water washing inlet 226, which is rotated towards the water washing duct 222 to open the water washing inlet 226, and is rotated towards the water washing inlet 226 to close the water washing inlet 226. This avoids that the inlet baffle 250 blocks the fresh air duct 221 and the fresh air inlet 225, and affects the air intake of the fresh air duct 221. In the embodiment, the fresh air inlet 225 and the water washing inlet 226 both extend out of the water storage, which can increase the contact time and contact area of the air in the water washing passage and the water in the water storage, so as to sufficiently humidify and purify the air.

[0069] In some other embodiments, a sealing structure 251 is arranged at the edge of the inlet baffle 250 to ensure the sealing of the fresh air duct 221. This is used to avoid air leakage of the fresh air duct 221, and thus avoid the fresh air duct 221 to suck indoor air, and improve the efficiency of the fresh air duct 221 to suck outdoor fresh air.
