Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1 and 2, fig. 1 and 2 show an indoor unit of a wall-mounted air conditioner in the present embodiment. The wall-mounted air conditioner may be a central air conditioner. The wall-mounted air conditioner includes a housing 1, a motor (not shown in the figure), a wind wheel 2, and an ionizer 3. The wind wheel 2 and the ion generator 3 are both arranged in the shell.

The housing 1 is provided with a first air inlet 12, a second air inlet 13, an air outlet 14, a main air duct 11 and a bypass air duct 10. The first air inlet 12, the second air inlet 13 and the air outlet 14 are arranged on the outer wall of the housing 1. The main air duct 11 and the bypass air duct 10 are both disposed in the housing 1. Two ends of the main air duct 11 are connected to a first air inlet 12 and an air outlet 14, respectively. The wind wheel 2 is arranged in the main air duct 11, and the wind wheel 2 divides the main air duct 11 into an air inlet duct 111 and an air outlet duct 112. The air inlet duct 111 is located between the wind wheel 2 and the first air inlet 12, and the air outlet duct 112 is located between the wind wheel 2 and the air outlet 14. A ventilation hole 1611 is formed in a wall surface of the intake air duct 111. One end of the bypass air duct 10 is connected to the second air inlet 13, and the other end of the bypass air duct 10 is connected to the ventilation hole 1611.

The wind wheel 2 is rotatably connected to the housing 1. The wind wheel 2 can rotate around its own axis. The motor is arranged at one end of the wind wheel 2. The main shaft of the motor is coaxial with the wind wheel 2 and is connected with the wind wheel 2. The motor is used for driving the wind wheel 2 to rotate.

The ionizer 3 is disposed in the bypass duct 10. The ionizer 3 includes an anode (not shown in the figure) and a cathode 31. The anode may be applied with a positive voltage or zero potential. The cathode 31 may be a carbon brush. The cathode 31 is applied with a negative dc high voltage. The voltage value across the cathode 31 may be greater than or equal to 2000V. After the cathode 31 is loaded with the dc negative high voltage, a large amount of electrons are released into the air, and these electrons are captured by oxygen molecules in the air to generate negative ions.

The ion generator 3 can generate a large amount of negative ions and a small amount of ozone at the same time, and the negative ions and the ozone can kill various viruses, bacteria and molds. The negative ions can also neutralize smoke dust with positive charges in the air, so that the smoke dust can be naturally settled, thereby purifying the air and eliminating the smoke dust.

When the wind wheel 2 rotates, negative pressure is generated in the intake air duct 111, a part of air enters the intake air duct 111 from the first air inlet 12, and another part of air enters the bypass air duct 10 from the second air inlet 13, and then enters the intake air duct 111 through the bypass air duct 10 and the air vent 1611. The air in the air inlet duct 111 is pressurized by the wind wheel 2 and then conveyed to the air outlet duct 112, and finally is output from the air outlet 14.

When the ion generator 3 works, negative ions and ozone generated by the ion generator 3 enter the air inlet duct 111 along with air flow from the bypass duct 10, and then are input into a room through the wind wheel 2 and the air outlet duct 112. The negative ions and the ozone can kill viruses, bacteria and molds in the main air duct 11 and the bypass air duct 10, purify the wall-mounted air conditioner, reduce the occurrence probability of air conditioner diseases and ensure the health of users. Meanwhile, the indoor air can be fresher.

In a related wall-mounted air conditioner technology, the ion generator 3 is disposed at the air outlet 14 or a position close to the air outlet 14, or is disposed in the air outlet duct 112, so that the installation of the ion generator 3 can block the normal air outlet of the wall-mounted air conditioner, so that the air outlet volume is reduced and/or the air supply distance is shortened. The ion generator 3 of the wall-mounted air conditioner in this embodiment is disposed in the side air duct 10, so as to avoid obstruction to the air outlet of the wall-mounted air conditioner.

In an exemplary embodiment, cathode 31 of ionizer 3 is proximate to vent 1611. The distance between the cathode 31 and the vent hole 1611 may be 3 to 20 mm.

In this way, the cathode 31 of the ion generator 3 is disposed close to the ventilation hole 1611, and the airflow passing through the bypass air duct 10 passes through the cathode 31 before being discharged from the ventilation hole 1611, so that the airflow can bring the negative ions generated near the cathode 31 into the intake air duct 111, and the negative ions can be fully utilized.

In one illustrative embodiment, the housing 1 includes a bezel 15, a bottom tray 16, and a drip tray 162.

The second air inlet 13 and the second air outlet 14 are arranged on two sides of the face frame 15, and the first air inlet 12 is arranged close to the second air inlet 13. In the present embodiment, the face frame 15 includes a top plate 151, a bottom plate 152, and a plurality of side plates 153.

The back plate 161 may extend from an edge of the first intake vent 12 near the second intake vent 13 to an edge of the outlet vent 14. The back plate 161 is configured as a substantially arc-shaped plate. The back plate 161 is arched toward a side facing away from the first intake vent 12.

A vent 1611 is provided on the back plate 161, and the vent 1611 penetrates the back plate 161. The face frame 15 and the back plate 161 enclose the bypass air duct 10.

In an exemplary embodiment, the top of the chassis 16 is also provided with a mounting slot 160. The mounting groove 160 is recessed toward the intake air duct 111, and the vent hole 1611 is formed at the bottom of the mounting groove 160. The top plate 151, the side plate 153 and the mounting groove 160 of the face frame 15 enclose a mounting cavity. An ionizer 3 is installed in the installation chamber. The second air inlet on the top plate 131 is communicated with the installation cavity. The installation cavity constitutes a bypass duct 10.

The installation cavity as the bypass duct 10 is located in the area between the face frame 15 and the base plate 16, and near the top of the face frame 15, which makes it possible to fully utilize the space of the back of the indoor unit of the wall-mounted air conditioner, making the indoor unit more compact.
