DETAILED DESCRIPTION

[0040] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the present application is described in detail below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other implementation methods obtained by ordinary technicians in the field without making creative work belong to the scope of protection of the present application.

[0041] Traditional air purification modules are fixed on the evaporator component or under the bottom shell. In the sweeping mode, only the sweeping air at a certain angle is blown directly into the air purification module. When the sweeping angle is rotated, the air passing through the air purification module becomes less or even does not pass through the air purification module, and the sterilization efficiency is low.

[0042] To solve this problem, the embodiment of the present application provides an air outlet device, wherein the air outlet device may be a device with a wind sweeping function such as an air conditioner, a humidifier or an air purifier. The embodiment of the present application takes an air conditioner as an example for explanation. Figure 1 and Figure 2 , including: an air sweeping device and an air purification module; wherein the air purification module can be any one or more of the following: a plasma generating device, an ultraviolet sterilization device.

[0043] The wind sweeping device is used to sweep the air to periodically change the air outlet angle of the air conditioner; Figure 1 As shown, the air sweeping device of the air conditioner includes a sweeping blade 101 for sweeping air left and right and a wind guide plate 105 for sweeping air up and down. Since the sweeping device is an existing structure, the present application will not repeat it here.

[0044] Although Figure 1 The air sweeping device in the given air conditioner includes air sweeping blades 101 for sweeping air left and right and an air guide plate 105 for sweeping air up and down, but in practice the air sweeping device in the air conditioner may only include air sweeping blades 101 for sweeping air left and right (or other names, but only for sweeping air left and right), or only include air guide plates 105 for sweeping air up and down (or other names, but only for sweeping air up and down).

[0045] Therefore, the wind sweeping device of the embodiment of the present application may include only the wind sweeping blades 101 for sweeping the wind left and right, or only the wind guide plate 105 for sweeping the wind up and down, or include both the wind sweeping blades 101 for sweeping the wind left and right and the wind guide plate 105 for sweeping the wind up and down. Those skilled in the art may select according to actual needs.

[0046] When the air sweeping device starts sweeping air, the air purification module moves accordingly as the air outlet angle of the air conditioner changes, so that the air purification module is always located at the maximum air outlet position.

[0047] It is understandable that if the air sweeping device includes both the air sweeping blades 101 for sweeping air left and right and the air guide plate 105 for sweeping air up and down, and only one air purification module is included, when the left and right air sweeping and the up and down air sweeping are turned on at the same time, the control of one air purification module cannot take into account both the left and right air sweeping and the up and down air sweeping.

[0048] Therefore, as a preferred implementation of the embodiment of the present application, when the wind sweeping device includes both the wind sweeping blade 101 for sweeping left and right and the wind guide plate 105 for sweeping up and down, the air purification module includes a first air purification module 102 and a second air purification module 106. The first air purification module 102 moves with the change of the wind outlet angle of the wind sweeping blade 101 when sweeping left and right, and the second air purification module 106 moves with the change of the wind outlet angle of the wind guide plate 105 when sweeping up and down.

[0049] The specific implementation of the air purification module moving with the air outlet angle is as follows:

[0050] The air conditioner also includes: a track and a power device;

[0051] The track is arranged along the wind sweeping direction of the wind sweeping device, and the power device drives the air purification module to move on the track along the wind outlet angle of the air conditioner.

[0052] The power device includes a motor 111, a wire reel, a wire and a chain;

[0053] The wire reel is used to recycle the wire and chain;

[0054] The chain is used to protect the wire; the wire is used to supply power to the air purification module; considering the basic principles of electrical safety design, flexible wires cannot be used directly as power traction lines, and must have a rigid support. In short, the principle is that the electrical wires cannot be directly subjected to force, otherwise it will affect the service life of the air purification module.

[0055] The chain and the wire are connected to the air purification module.

[0056] In one embodiment, the motor 111 is connected to the cable reel;

[0057] When the motor 111 rotates, the wire reel drives the chain to move, and when the chain moves, it drives the air purification module to move on the track.

[0058] Among them, the results of the reel are as follows Figure 3As shown, it includes an upper cover 112, a rotating gear 113, a winding support column 114 and a lower cover 115. The upper cover 112 and the lower cover 115 are combined to protect the winding support column 114 and the rotating gear 113 in the space formed by the two. The motor 111 is connected to the rotating gear 113 through the motor 111 shaft, and the rotating gear 113 is connected to the winding support column 114 so as to drive the winding support column 114 to retract the chain and the wire, or release the chain and the wire.

[0059] In this embodiment, the movement of the air purification module is driven by a chain. When controlling, it is only necessary to control the motor 111 to drive the wire reel to retract or release the chain. Therefore, there are certain requirements for the chain, which requires that when the motor 111 drives the wire reel to release the chain, the chain can push the air purification module to move.

[0060] In another embodiment, the motor is disposed on the air purification module, and the wire is also used to supply power to the motor;

[0061] The motor directly drives the air purification module to move on the track;

[0062] A spring is arranged inside the cable reel, and the spring can retract the wire and the chain when the air purification module approaches the cable reel.

[0063] That is, in the embodiment of the present application, the motor directly drives the air purification module to move, and there is no requirement for the chain. It only needs to protect the wire from being broken when the air purification module moves. Because when the air purification module is far away from the reel, the chain is directly pulled out from the reel, and the spring can retract the wire and chain when the air purification module is close to the reel. The principle of spring recovery is the same as the principle of automatic recovery of the tape measure, so the specific setting is not described in detail here.

[0064] Of course, the spring may not be provided, but a motor may be provided at the outlet of the cable reel, and the two motors of the air purification module and the cable reel may work together to release and retract the wire and chain.

[0065] In actual use, when the air purification module moves directly on the track, due to the large contact area, the friction is large, it consumes more power, and is easy to cause noise. Therefore, as a preferred implementation method of the embodiment of the present application, the air purification module is provided with a sliding device, and the air purification module moves on the track through the sliding device. An exemplary sliding device is a roller or a ball. The roller and the ball can prevent the air purification module from contacting the track as a whole, reduce the contact area, reduce friction, reduce power consumption, and reduce noise.

[0066] It should be noted that the present application may also not set up tracks, but instead set up cables, and the air purification module moves along the cables driven by a power device, similar to a cable car.

[0067] The air conditioner provided in the embodiment of the present application includes an air sweeping device and an air purification module. The air sweeping device is used to sweep the air to periodically change the air outlet angle of the air conditioner. When the air sweeping device starts to sweep the air, the air purification module moves with the air outlet angle of the air conditioner so that the air purification module is always located at the maximum air outlet position. Since the air purification module in the present application scheme can move with the air outlet angle of the air conditioner when the air sweeping device sweeps the air, that is, the position of the air purification module changes when the air outlet angle changes, the problem that when the air purification module is fixedly installed, after the air sweeping is turned on, the air passing through the air purification module becomes less, resulting in a decrease in the sterilization efficiency, is solved. Since the air purification module is always located at the maximum air outlet position, the sterilization efficiency is guaranteed.

[0068] The following is an example of an air conditioner in which the air sweeping device includes both air sweeping blades 101 for sweeping air left and right and air guide plates 105 for sweeping air up and down.

[0069] like Figure 1 and Figure 2 As shown, the air purification module includes a first air purification module 102, the track includes a first track 103, the power device includes a first power device, the first power device includes a first motor and a first reel 104, and the first motor retracts or releases the first chain and wire 109 through the first reel 104 to drive the first air purification module 102 to move.

[0070] When the air sweeping device starts to sweep the air left and right, the first power device drives the first air purification module 102 to move left and right on the first track 103 .

[0071] As a preferred implementation method of the embodiment of the present application, the first track 103 is arranged at the top or bottom of the air outlet of the air conditioner along the left and right direction. Theoretically, when the first track 103 is arranged in the middle, the sterilization effect is better, but when it is arranged in the middle, the first air purification module 102 needs to be structurally fixed, and its own structure will have a greater impact on the air output. Therefore, when sweeping the air left and right, it is generally set at the top or bottom, which does not affect the air output.

[0072] The air purification module includes a second air purification module 106, the track includes a second track 107, and the power device includes a second power device; the second power device includes a second motor and a second reel 108, and the second motor retracts or releases the second chain and wire 110 through the second reel 108 to drive the second air purification module 106 to move.

[0073] When the air sweeping device starts to sweep the air up and down, the second power device drives the second air purification module 106 to move up and down on the second track 107 .

[0074] As a preferred implementation of the present application, the second track 107 is arranged in the middle of the air conditioner along the vertical direction. Therefore, when sweeping air up and down, the length from the top to the bottom is short, so it can be directly arranged in the middle, which has the best sterilization effect.

[0075] Of course, it can also be set on the left or right side according to actual needs.

[0076] It should be noted that the first track 103 and the second track 107 are independent of each other, and the movements of the first air purification module 102 and the second air purification module 106 do not affect each other.

[0077] like Figure 1 and Figure 2 The "T"-shaped sliding track shown is integrated into the bottom shell component and installed with the air purification module. A roller is designed under the air purification module. The roller and the sliding track are embedded in each other to achieve the electrically driven controllable sliding of the air purification module. A groove structure is designed on the bottom shell to fix the reel and the stepper motor 111 synchronously. At the same time, a wire groove is designed on the bottom shell for the wire routing. The overall effect is shown in Figure 2 .

[0078] The embodiment of the present application designs a "T"-shaped track on the air conditioner, and when the air conditioner enters the wind sweeping mode, the "high-efficiency sterilization" mode is turned on. When the air conditioner enters the left and right wind sweeping mode, the first air purification module 102 on the horizontal "I"-shaped track (i.e., the first track 103) is turned on and moves. When the air conditioner enters the up and down wind sweeping mode, the second air purification module 106 on the vertical "1"-shaped track (i.e., the second track 107) is turned on and moves. The first air purification module 102 and the second air purification module 106 will move with the movement of the wind sweeping blades 101 and the air guide plate 105, respectively, so as to achieve the maximum sterilization effect of air purification.

[0079] Based on the same inventive concept, Figure 4 As shown, the present application provides a method for controlling an air outlet device, which is applied to the air outlet device provided in any of the above embodiments, and the method includes:

[0080] S41: when it is detected that the air outlet device starts to sweep air, obtaining the sweeping mode of the air outlet device;

[0081] S42: Based on the wind sweeping mode, controlling the air purification module corresponding to the wind sweeping mode to turn on and move.

[0082] Specifically, a specific air conditioner control method is provided below, such as Figure 5 As shown:

[0083] The user uses the remote control to turn on the device, turn on the health function, and turn on the wind sweeping mode.

[0084] When the left and right wind sweeping mode is started, the "I"-shaped high-efficiency sterilization mode enters the working state, the main board of the controller receives the left and right wind sweeping function start signal, and the main board synchronously outputs a high-frequency signal to the air purification module 1 (i.e., the first air purification module), thereby waking up the stepper motor 1 to start, and the stepper motor 1 drives the air purification module 1 to enter the left and right movement mode. When the wind sweeping blade sweeps the left, the main board receives the left wind sweeping signal, and the main board outputs a feedback signal to control the stepper motor 1 to rotate forward, and the stepper motor shaft synchronously drives the power traction chain to move to the left. At the same time, the air purification module 1 moves to the left under the push of the power traction chain (at this time, the power traction chain is pulled out from the first reel), and the pace of moving to the left is completely consistent with the pace of the wind sweeping blade (the embodiment of the present application designs a roller at the bottom of the air purification module 1, and the roller and the first track are embedded in each other, so as to realize the electrically driven controllable sliding of the air purification module 1, reduce the resistance, and at the same time achieve the effect of reducing noise.

[0085] Similarly, when the wind sweeping blade sweeps to the right, the main board receives the right wind sweeping signal, and the main board outputs a feedback signal to control the stepper motor 1 to reverse, and the stepper motor shaft synchronously drives the power traction chain to move to the right. At the same time, the air purification module 1 moves to the right under the push of the power traction chain (at this time the power traction chain is retracted into the first reel), and the pace of movement to the right is completely consistent with the pace of the wind sweeping blade.

[0086] The purpose of the above scheme design is to ensure that the air purification module 1 can always be at the maximum air outlet, maximizing the sterilization efficiency of the air purification module 1. When the user stops the left and right sweeping function, the stepper motor 1 will also stop rotating immediately, but the air purification module 1 is still in the on state, still at the maximum air volume position to continue sterilizing, and the sterilization effect is still in the most efficient sterilization state. The air purification module will not stop working until the user stops the health function.

[0087] When the up and down sweeping mode is started, the "1"-shaped high-efficiency sterilization mode enters the working state, the mainboard of the controller receives the up and down sweeping signals, and the mainboard synchronously outputs a high-frequency signal to the air purification module 2 (i.e., the second air purification module), thereby waking up the stepper motor 2 to start, and the stepper motor 2 drives the air purification module 2 to enter the up and down movement mode. When the sweeping blades perform upward sweeping, the mainboard receives the upward sweeping signal, and the mainboard outputs a feedback signal to control the stepper motor 2 to rotate forward, and the stepper motor shaft synchronously drives the power traction chain to move upward. At the same time, the air purification module 2 moves upward under the push of the power traction chain (at this time, the power traction chain is pulled out from the second reel), and the pace of the upward movement is completely consistent with the pace of the sweeping blades (the present invention designs a roller on the air purification module 2, and the roller and the second track are mutually embedded to achieve the electrically driven controllable sliding of the air purification module 2, reduce resistance, and at the same time achieve the effect of reducing noise;

[0088] Similarly, when the wind sweeping blades are sweeping downward, the main board receives a downward sweeping signal, and the main board outputs a feedback signal to control the stepper motor 2 to reverse, and the stepper motor shaft synchronously drives the power traction chain to move downward. At the same time, the air purification module 2 moves downward under the push of the power traction chain (at this time the power traction chain is retracted into the second reel), and the pace of the downward movement is completely consistent with the pace of the wind sweeping blades.

[0089] The purpose of the above scheme design is to ensure that the air purification module 2 can always be at the maximum air outlet, maximizing the sterilization efficiency of the air purification module. When the user stops the up and down sweeping function, the stepper motor 2 will also stop rotating immediately, but the air purification module 2 is still in the on state, still at the maximum air volume position to continue sterilizing, and the sterilization effect is still in the most efficient sterilization state. The air purification module 2 will not stop working until the user stops the health function.
