[0026] The air conditioner indoor unit of the present invention comprises an indoor unit housing, an air duct component 10 and a negative ion absorption device 20, both of which are arranged in the indoor unit housing; the negative ion absorption device 20 is connected with the air duct inner cavity 11 of the air duct component 10, so that the negative ions in the negative ion absorption device 20 absorb the impurities in the air duct component 10. The negative ion absorption device 20 of the air conditioner indoor unit can absorb bacteria and dust in the air duct inner cavity, so that the air duct inner cavity remains continuously clean and the air blown out of the air outlet of the air conditioner indoor unit remains continuously fresh and refreshing.

[0027] Specifically, the negative ion absorption device 20 is installed in the indoor unit of the cabinet air conditioner.

[0028] Among them, impurities include dust and bacteria.

[0029] In this embodiment, the negative ion absorption device 20 includes: an absorption device housing 21; a negative ion pipeline 22, at least part of which is disposed in the absorption device housing 21, and the negative ion pipeline 22 is used to contain negative ions; absorption holes are disposed on the pipeline wall of the negative ion pipeline 22, so that impurities entering the negative ion absorption device 20 from the air duct component 10 are absorbed into the negative ion pipeline 22 through the absorption holes under the action of negative ions. Such a configuration maximizes the absorption of bacteria and dust, and achieves the optimal effect of sterilization and dust removal.

[0030] In specific implementation, the negative ion pipeline 22 has a negative ion inlet 221 and a negative ion outlet 222, and the negative ion inlet 221 and the negative ion outlet 222 are located on the outside of the absorption device shell 21; negative ions enter the negative ion pipeline 22 from the negative ion inlet 221, and the negative ions in the negative ion pipeline 22 combine with impurities and aggregate before being discharged through the negative ion outlet 222.

[0031] In this embodiment, the negative ion absorption device 20 further includes a fan blade disposed in the absorption device housing 21 . The fan blade is rotatably disposed so that gas convection occurs between the negative ion absorption device 20 and the air duct component 10 .

[0032] In order to realize the rotation of the fan blades, the negative ion absorption device 20 further includes a driving device, which is arranged in the absorption device housing 21, and the driving device is connected to the fan blades to drive the fan blades to rotate.

[0033] Preferably, the driving device is a motor.

[0034] Preferably, the air duct component 10 extends in a vertical direction, and the negative ion absorption device 20 is disposed below the air duct component 10 .

[0035] In this embodiment, a first connecting port 12 is provided on the air duct component 10, a second connecting port is provided on the negative ion absorption device 20, and the air conditioner indoor unit also includes a connecting pipe, one end of the connecting pipe is connected to the first connecting port 12, and the other end of the connecting pipe is connected to the second connecting port.

[0036] Preferably, the communicating pipe is a rubber tube.

[0037] Preferably, the air conditioner indoor unit further comprises a first connection part 30, which is a tubular structure, and has a first connection port and a second connection port, the first connection port is adapted to the first connecting port, and the first connection port is connected to the first connecting port 12; the second connection port is used to connect to an end of the connecting pipe away from the negative ion absorption device 20; wherein the tube wall of the tubular structure is a conical structure, and the opening area of ​​the first connection port is larger than the opening area of ​​the second connection port. Such a setting increases the contact area of ​​negative ion absorption, so that the absorption effect of dust and bacteria is better.

[0038] Specifically, the opening area of ​​the first communication port 12 is larger than the opening area of ​​the second communication port.

[0039] In this embodiment, the absorption device housing 21 includes a first housing 211 and a second housing 212, which are detachably arranged. The absorption device housing 21 has a receiving cavity, in which at least part of the negative ion pipeline 22, the fan blades and the driving device are arranged.

[0040] Specifically, the negative ion absorption device is a structure containing negative ions to absorb and remove bacteria and dust inside the air duct component, thereby solving the problem of dust adhesion and bacteria breeding in the air duct component and the cross-flow fan blades of the air duct component during long-term operation.

[0041] Since the long-term operation of the air duct blades will inevitably generate dust and breed bacteria, it is easy to cause dust particles and bacteria to be generated after the air conditioner blows out air over time, affecting the health of users and causing poor user experience. The present invention is specially designed with a negative ion absorption structure device for removing bacteria and dust inside the air duct components. The bacteria and dust inside the air duct components are absorbed synchronously during the operation of the air conditioner, and fresh air is blown out to give users the best air experience.

[0042] A negative ion absorption device is placed under the air duct component of the air conditioner indoor unit. The negative ion absorption device and the air duct inner cavity of the air duct component are connected by a rubber tube. During the operation of the cross-flow fan blades of the air duct component, dust and bacteria are easily scattered in the air duct inner cavity, and the negative ion absorption device absorbs the dust and bacteria through the ion effect.

[0043] The first connecting port where the air duct component cooperates with the rubber tube is designed to be a large bell mouth (that is, a first connecting portion is provided at the first connecting port), which increases the contact area for negative ion absorption and makes the dust and bacteria absorption effect better.

[0044] The negative ion absorption device contains negative ion pipelines for the flow of negative ions in and out. The negative ions are purified through continuous circulation in and out to maximize the absorption of bacteria and dust, achieving the optimal effect of sterilization and dust removal.

[0045] The negative ion absorption device is composed of a negative ion pipeline, a motor, a first shell and a second shell. Negative ions are stored in the negative ion pipeline. When the motor inside the negative ion absorption device is running, the negative ions are driven to circulate, and then the bacteria and dust in the air duct cavity are driven to be absorbed into the negative ion pipeline through the connecting pipe through the ion effect. The negative ions circulate in the negative ion pipeline, continuously purifying the negative ions that have absorbed bacteria and dust in the negative ion pipeline, so that the negative ions flowing through the negative ion pipeline absorb bacteria and dust with the best absorption effect. When the indoor unit of the air conditioner is running, bacteria and dust are easily generated in the air duct cavity, which will be deposited and accumulated at the bottom of the air duct cavity for a long time. The negative ion absorption device will absorb the bacteria and dust in the air duct cavity through its unique ion effect, and the negative ions themselves are constantly in and out to replace new negative ions. Through continuous circulation and renewal of negative ion absorption, the air duct cavity is continuously kept clean and the air blown out of the air outlet of the air conditioner is kept fresh and refreshing. The negative ion absorption device can not only keep the inner cavity of the air duct clean, but also keep the air output of the air conditioner fresh, giving users the best fresh air experience.

The negative ion absorption device 20 of the air conditioner indoor unit can absorb bacteria and dust in the air duct inner cavity, so that the air duct inner cavity remains continuously clean and the air blown out of the air outlet of the air conditioner indoor unit remains continuously fresh and refreshing.
