The number of the rotating positions of the swing blades 3 is at least two, and the rotating positions correspond to the positioning positions one by one; the swing blade 3 is positioned at a certain rotation position by the electromagnet 2 and the adsorption member 6 adsorbed at a certain positioning position.

Specifically, taking three positioning positions and three rotating positions as an example, when the electromagnet 2 and the adsorbing member 6 are adsorbed at one positioning position, the swing blade 3 rotates to one rotating position and is positioned at the rotating position; when the electromagnet 2 and the adsorption piece 6 are adsorbed at the other positioning position, the swinging blade 3 rotates to the other rotating position and is positioned at the rotating position; when the electromagnet 2 and the adsorption member 6 are adsorbed at the other positioning position, the swing blade 3 rotates to the other rotation position and is positioned at the rotation position.

In the above-described vane positioning structure, when the circuit is turned on, the electromagnet 2 and the adsorbing member 6 are adsorbed at only one positioning position. In order to ensure the rotation of the swinging blade 3, the positioning positions are distributed along an arc line. The distance between two adjacent positioning positions is designed according to the required rotation position of the swing blade 3. Preferably, the above positioning positions are evenly distributed along the arc.

Because the swinging blade 3 is positioned by adopting electromagnetic adsorption, abrasion is difficult to occur, and even if the abrasion occurs, the adsorption of the electromagnet 2 and the adsorption piece 6 is not influenced, therefore, compared with the prior art, the probability of positioning failure of the swinging blade 3 is reduced, and the reliability of positioning the swinging blade 3 is effectively improved.

In the above-mentioned swing blade positioning structure, the electromagnet 2 may be disposed on the bearing member 1, or may be disposed on the swing blade 3. For the sake of convenience, the electromagnet 2 is preferably arranged on the carrier 1, and in this case, the suction element 6 is arranged on the flap 3. Specifically, the adsorption piece 6 is an iron piece, and the circuit controls the electromagnet 2 to be powered on and off.

The circuit controls the electromagnet 2 to be powered on and powered off, and means that the circuit can realize the powering on of the electromagnet 2 and the powering off of the electromagnet 2. The electromagnet 2 is magnetized when being electrified and is not magnetized when being powered off, namely, the circuit controls the magnetism of the electromagnet 2. Specifically, when the circuit is closed, the electromagnet 2 is energized; when the circuit is open, electromagnet 2 is de-energized.

In order to simplify the structure and facilitate control, it is preferable to select the electromagnets 2 in one-to-one correspondence with the positioning positions.

The number of the swing blades 3 can be one or more. In order to improve the wind guiding effect, at least two swinging blades 3 are preferably selected and are sequentially distributed along the length direction of the bearing piece 1. Specifically, if there are at least two swing blades 3, there are at least two sets of positioning positions, each swing blade 3 corresponds to one set of positioning position, and each set of positioning position has at least two positioning positions. At this time, at least two groups of electromagnets 2 are arranged, and the electromagnet groups correspond to the positioning position groups one by one.

In order to ensure that all the swinging blades 3 swing to any one same rotating position at the same time, any two swinging blades 3 are preferably selected to have the same rotating position, and any two groups of positioning positions have the same positioning position; the circuit controls all groups of electromagnets 2 at the same positioning position to be powered on and powered off simultaneously.

Specifically, as shown in fig. 5 and 6, the number of the swing vanes 3 is 8, the positioning positions are eight, and correspondingly, the number of the electromagnets 2 is eight, and the eight are respectively a first electromagnet group 2A, a second electromagnet group 2B, a third electromagnet group 2C, a fourth electromagnet group 2D, a fifth electromagnet group 2E, a sixth electromagnet group 2F, a seventh electromagnet group 2G, and an eighth electromagnet group 2H. Each oscillating vane 3 has five rotational positions, and correspondingly, for each oscillating vane 3, one group of positioning positions has five positioning positions, and each group of electromagnets 2 has five electromagnets 2, namely a first electromagnet a, a second electromagnet b, a third electromagnet c, a fourth electromagnet d and a fifth electromagnet e.

The coils of the electromagnets 2 at the same positioning position are connected with the same wire, so that five wires are shared, and the five wires form a wire group 4. When the circuit is on, only one wire of the set of wires 4 is energized. Furthermore, only one electromagnet 2 in each set of electromagnets 2 has magnetism, and the electromagnets 2 having magnetism in each set are located at the same positioning position.

As shown in fig. 6, when the fifth electromagnet e of a certain electromagnet group is energized and magnetized, the fifth electromagnets e of the other electromagnet groups are also energized and magnetized, and the other electromagnets 2 in all electromagnet groups are not energized and magnetized. Furthermore, the iron member on each of the swinging blades 3 is attracted by the fifth electromagnet e in each group of electromagnets, so that each of the swinging blades 3 swings to the same rotational position at the same time.

The carrier 1 needs to be provided with an electric circuit, and therefore, in order to facilitate the installation of the electric circuit, the carrier 1 is a volute tongue. Of course, the carrier 1 may be selected as another fixing component, and is not limited to the above embodiment.

In the above-described vane positioning structure, the electromagnet 2 may be provided on the vane 3, the attracting member 6 may be provided on the carrier 1, and the attracting member 6 may be a magnet. At this time, the number of the rotating positions and the positioning positions is two, the circuit controls the direction of the current flowing through the electromagnet 2, and correspondingly, the number of the rotating positions of the swinging blade 3 is two.

It is understood that there may be one or more than two suction members 6 at one positioning position. In order to simplify the structure, the suction members 6 are preferably selected to correspond one-to-one to the positioning positions.

Preferably, there are at least two swing blades 3, there are at least two groups of positioning positions, and each swing blade 3 corresponds to one group of positioning positions; any two swinging blades 3 have the same rotating position, and any two groups of positioning positions have the same positioning position; the circuit controls the current flowing through all the electromagnets 2 to be in the same direction. At the moment, at least two groups of magnets are arranged, and the magnet groups correspond to the positioning position groups one by one.

It will be appreciated that in each set of detent positions, there are two detent positions. Each set of magnets has two magnets, one with the N pole facing electromagnet 2 and the other with the S pole facing electromagnet 2.

Take the example where the N-pole of the electromagnet 2 faces the magnet when a positive current is flowing through the electromagnet 2. When the electromagnet 2 is electrified with positive current, the electromagnet 2 and the magnet with the S pole facing the electromagnet 2 are adsorbed, and the swing blade 3 rotates to the positioning position where the magnet with the S pole facing the electromagnet 2 is located; on the contrary, when the electromagnet 2 is energized with a negative current, the S pole of the electromagnet 2 faces the magnet, the electromagnet 2 is attracted by the magnet with the N pole facing the electromagnet 2, and the swing blade rotates to the positioning position where the N pole faces the magnet of the electromagnet 2.

As shown in fig. 8 and 9, for example, nine oscillating vanes 3 are provided, and if one electromagnet 2 is provided for each oscillating vane 3, nine electromagnets 2 are provided, and all the electromagnets 2 are connected in series in sequence and form a circuit with a power supply through a double-pole double-throw gang switch. As shown in fig. 8, the double pole double throw ganged switch is closed in the first position, and a positive current flows through the electromagnet 2; as shown in fig. 9, the double pole double throw ganged switch is closed in the second position and a negative current flows through the electromagnet 2. The circuit thus controls the direction of the current through the electromagnet 2.

In the above-mentioned swing blade positioning structure, the bearing member 1 is a volute tongue or other fixed component, so as to ensure that the swing blade 3 rotates to a desired rotation position. The bearing part 1 can also be a wind deflector 8, which is only complex to realize.

In the above-mentioned pendulum vane positioning structure, in order to facilitate the electromagnet 2 and the adsorbing member 6 to adsorb, one of the electromagnet 2 and the adsorbing member 6, which is disposed on the pendulum vane 3, is located at one end of the pendulum vane 3 close to its rotation axis. For example, the suction member 6 is provided on the swing blade 3, and the suction member 6 is located at an end of the swing blade 3 near its rotation axis. Thus, the distance between the suction member 6 and the electromagnet 2 can be shortened as much as possible, and the suction reliability can be improved.

Of course, one of the electromagnet 2 and the attraction member 6 disposed on the swing blade 3 may be located at another position of the swing blade 3 as long as it is closer to the rotation axis of the swing blade 3.

It will be understood that if the swing blade 3 is disposed on the carrier 1 through the rotating shaft 5, the rotating axis is the axis of the rotating shaft 5.

In order to reduce wear, when the electromagnet 2 is arranged on the carrier 1, the carrier 1 is provided with a through hole at a positioning position where the electromagnet 2 is exposed; when the suction member 6 is provided on the carrier 1, the carrier 1 is provided at the positioning position with a through hole through which the suction member 6 is exposed. Specifically, the through holes correspond to the positioning positions one by one. Thus, when the electromagnet 2 and the adsorption piece 6 are adsorbed, the electromagnet and the adsorption piece are not in direct contact, so that abrasion is reduced, and positioning reliability is improved.

For the convenience of wiring, one of the swing blade 3 and the carrier 1 provided with the electromagnet 2 has a receiving groove 11, and the receiving groove 11 receives the wire group 4 of the circuit.

When the carrier 1 is provided with the through hole, the accommodating groove 11 also accommodates one of the electromagnet 2 and the adsorbing member 6 on the carrier 1.

The swinging of the swinging blade 3 can be operated by hands. Specifically, the above-mentioned swing vane positioning structure further includes a knob switch 10 of the control circuit, as shown in fig. 5 and 10.

Specifically, if the circuit controls the electromagnets 2 in the same positioning position of all the groups to be powered on and off simultaneously, as shown in fig. 7, when the knob switch 10 is turned, the circuit is turned off, and when the knob switch 10 is turned to a set position, one conducting wire in the circuit is turned on, thereby controlling the electromagnets 2 in the same positioning position of all the groups to be powered on and off simultaneously.

If the current direction flowing through all the electromagnets 2 is controlled by the circuit to be the same, as shown in fig. 8 and 9, when the knob switch 10 is rotated, the double-pole double-throw ganged switch is actuated, and when the knob switch 10 is turned to a set position, the closed state of the double-pole double-throw ganged switch is changed, so that the connection state of the circuit is changed to switch the current flow direction of the circuit, and the control circuit controls the current direction flowing through all the electromagnets 2 to be changed.

Preferably, the knob switch 10 is disposed outside the outlet 9. For example, the knob switch 10 is located on one side of the air outlet 9 along the length direction of the casing 7 of the air conditioner indoor unit.

The structure is convenient for a user to touch and use the knob switch 10, improves the use safety and avoids the hand of the user from being injured by components such as a fan and the like.

The shape of the placing groove 701 is selected according to actual needs, for example, the placing groove 701 is a cylindrical groove, which is not limited in this embodiment.

The swing blade 3 can also swing automatically, and specifically, the swing blade positioning structure further includes: a circuit board of the control circuit. Thus, the swinging blade 3 automatically swings.

Based on the swing blade positioning structure provided by the above embodiment, the present embodiment further provides an air conditioner internal unit, where the air conditioner internal unit includes a swing blade positioning structure, and the swing blade positioning structure is the swing blade positioning structure described in the above embodiment.
