Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning devices, in particular to an air-conditioning indoor unit. Background Art

[0002] Conventional cabinet air conditioners with a water-washing, humidifying, and purification function typically use a centrifugal fan to draw indoor air into the water tank through the air inlet. The air is then purified by a water curtain driven by the rotating blades before being blown out. When the cabinet has a fresh air function, a centrifugal fan typically draws outdoor air into the fresh air duct, where it is purified by a purification module before being blown out. Having separate centrifugal fans for the water-washing, humidifying, and purification functions and the fresh air function increases the number of components within the cabinet, leading to an illogical component layout and high costs.

When the second regulating device 402 connects the air outlet 212 and the air flow outlet 102, the outlet air flow includes airflow that has been washed, humidified and purified; when the second regulating device 402 connects the outdoor fresh air inlet 103 and the air flow outlet 102, the outlet air flow includes outdoor fresh air that has not been washed, humidified and purified; when the second regulating device 402 connects the air outlet 212 and the air flow outlet 102, the outdoor fresh air inlet 103 and the air flow outlet 102, the outlet air flow includes both airflow that has been washed, humidified and purified, and outdoor fresh air that has not been washed, humidified and purified.

[0037] like Figure 2 As shown, an air duct housing 106 is disposed within the housing 101; an air inlet 160 is provided on the air duct housing 106. Indoor air enters the housing 101 through the indoor air inlet 150 and then enters the air duct housing 106 through the air inlet 160. The water washing device 200, the first regulating device 401, and the second regulating device 402 are all disposed within the air duct housing 106. By disposing the air duct housing 106 within the housing 101, the water washing device 200, the first regulating device 401, and the second regulating device 402 are all disposed within the air duct housing 106, making it convenient to dispose the first regulating device 401 and the second regulating device 402 within the housing 101.

[0038] In some embodiments, in the air-conditioning indoor unit 100 of the embodiment of the present invention, the air duct shell 106 is formed with: a first air duct 161 connecting the outdoor fresh air inlet 103 and the air flow outlet 102, a second air duct 162 connecting the air inlet 160 and the air inlet 211, and a third air duct 163 connecting the air outlet 212 and the air flow outlet 102; the first regulating device 401 is controlled to conduct the first air duct 161 and / or the second air duct 162; the second regulating device 402 is controlled to conduct the first air duct 161 and / or the third air duct 163.

[0039] In the air conditioner indoor unit 100 of the embodiment of the present invention, when the user turns on the outdoor fresh air function alone, as shown in FIG. Figure 3 As shown, the second regulating device 402 connects the outdoor fresh air inlet 103 and the air outlet 102. At this time, the first regulating device 401 does not connect the outdoor fresh air inlet 103 and the air inlet 211, so that the outdoor fresh air directly reaches the air outlet 102 through the first air duct 161.

[0040] When the user turns on the water washing, humidification and purification function separately, such as Figure 4 As shown, the first regulating device 401 connects the indoor air inlet 150 and the air inlet 211, and the second regulating device 402 connects the air outlet 212 and the air flow outlet 102. The indoor air enters the air duct shell 106 through the indoor air inlet 211 and the air inlet 160, reaches the air inlet 211 through the second air duct 162 and enters the water washing device 200, and then flows into the third air duct 163 through the air outlet 212 until it reaches the air flow outlet 102.

[0041] When the user turns on the outdoor fresh air function and the water washing humidification and purification function, Figure 5 As shown, the first regulating device 401 connects the outdoor fresh air inlet 103 and the air inlet 211, and the second regulating device 402 connects the air outlet 212 and the air outlet 102. Outdoor fresh air enters the air duct housing 106 through the outdoor fresh air inlet 103, passes through the first air duct 161 to the air inlet 211, enters the washing device 200, and then flows through the air outlet 212 into the third air duct 163 until it reaches the air outlet 102.

[0042] In some embodiments, in the air conditioning indoor unit 100 of the embodiment of the present invention, the first regulating device 401 includes a first damper 411 rotatably disposed at the connection between the first air duct 161 and the second air duct 162. The second regulating device 402 includes a second damper 421 rotatably disposed at the connection between the first air duct 161 and the third air duct 163. Figure 2 As shown, the first regulating device 401 further includes a first motor 412, the output shaft of which is connected to the first damper 411 to drive the first damper 411 to rotate; the second regulating device 402 further includes a second motor 422, the output shaft of which is connected to the second damper 421 to drive the second damper 421 to rotate. By configuring the first regulating device 401 to include the first damper 411 and the first motor 412, the first regulating device 401 has a simple structure and is easy to configure. By configuring the second regulating device 402 to include the second damper 421 and the second motor 422, the second regulating device 402 has a simple structure and is easy to configure.

[0043] The air conditioner indoor unit 100 of the embodiment of the present invention further includes a centrifugal fan 203 . The centrifugal fan 203 is disposed above the water tank 201 , and its inlet is connected to the outlet of the air duct housing 106 , and its outlet is connected to the airflow outlet 102 .

[0044] like Figure 1 As shown, the air-conditioning indoor unit 100 of the embodiment of the present invention is a vertical air-conditioning indoor unit 100; the water tank 201 is arranged at the lower part of the interior of the casing 101; an air inlet 211 is opened at the rear wall of the water tank 201, and an air outlet 212 is opened at the top wall; the outdoor fresh air inlet 103 is opened at the lower back part of the casing 101.

[0045] Continue to refer Figure 1 The housing 101 includes a maintenance panel 105 located at the lower back of the housing 101; an indoor air inlet 150 is provided on the maintenance panel 105. By providing the indoor air inlet 150 on the maintenance panel 105, the indoor air inlet 150 is close to the air inlet 160, allowing air to be conveniently introduced into the water tank 201 to achieve water washing, humidification and purification of the indoor air. A main air inlet 104 is provided at the upper back portion of the housing 101, and a main air outlet (not shown) may be provided at the upper front portion of the housing 101. Indoor air enters the housing 101 through the main air inlet 104, undergoes heat exchange in the heat exchanger, and forms a heat exchange airflow, which is then discharged into the room through the main air outlet.

[0046] Figure 6 yes Figure 2 The structure diagram of the rotating plate 221 of the drum 202 of the water washing device 200 of the air conditioner indoor unit 100 is shown. Figure 2 and Figure 6 As shown, a drum 202 is disposed within a water tank 201, wherein the drum 202 is rotatably disposed within the water tank 201. In some embodiments, the drum 202 is configured to be rotatably disposed within the water tank 201 about a horizontally extending rotation axis 223. The drum 202 includes a plurality of rotating plates 221 arranged in a centrally radiating pattern centered around the rotation axis 223, each of the rotating plates 221 having a plurality of honeycomb holes 222. The drum 202 is configured to remove water from the water tank 201 through the honeycomb holes 222 on the rotating plates 221 during rotation. This allows airflow to blow away the water held in the honeycomb holes 222 when it flows head-on toward the rotating plates 221, thereby washing, humidifying, and purifying the airflow with the water held in the honeycomb holes 222. The honeycomb holes 222 retain a larger amount of water, thereby increasing the amount of water removed from the rotating plates 221 and improving the purification effect and efficiency of the airflow.
