[0002] With the continuous improvement of living standards, people's comfort requirements for air conditioners are also getting higher and higher. In order to ensure the uniformity of indoor air temperature, the current household air conditioner realizes the control of wind direction by realizing the functions of up-down and left-right wind sweeping through the up-down swing of the air deflector and the left-right swing of the air sweeping blade. However, in the process of use, the air volume of the blowing area is relatively concentrated, and the cold or hot air blown by the air conditioner will directly blow on the user, affecting the user's experience.

[0060] Referring to Figure 1 and Figure 5 , according to an embodiment of the present application, a soft wind device is provided, referring to Figure 1 , the soft wind device comprises:

[0061] A first soft wind blade group (not labeled in the figure) comprises a plurality of blades 1 arranged at intervals along a first direction, the blade 1 comprises a left side piece 11 and a right side piece 12, the first side of the left side piece 11 is connected to the first side of the right side piece 12, the blade 1 has an open state in which the left side piece 11 and the right side piece 12 are oppositely open, when the air conditioner to which the soft wind device is applied operates in a soft wind mode, the blade 1 is in the open state, when the blade 1 is in the open state, the left side piece 11 and the right side piece 12 form an acute angle and the first side is on the upstream side of the airflow outflow direction, the upstream side is relative to the downstream side of the airflow outflow direction. The aforementioned first direction is, for example, a straight line direction perpendicular to the airflow outflow direction, when the air conditioner is a horizontal wall-mounted machine and the air outlet is a horizontally extending strip structure, the aforementioned first direction is the horizontal direction.

[0062] In this technical solution, each blade in the first soft wind blade group has an open state, in the soft wind mode, the blade 1 opened at an acute angle can form a barrier to the outflow air flow and change the flow direction of the outflow air flow, effectively preventing the discomfort caused by the outflow air flow directly blowing on the user, at the same time, the blade 1 in the present application realizes the soft wind effect by opening instead of the micro-hole structure in the prior art, eliminating the phenomenon of easy clogging of the micro-hole structure. Compared with the micro-hole structure, the use of the blade 1 of the present application for soft wind treatment has a smaller loss of air volume.

[0063] Referring to Figure 3 , the fan 40 of the air conditioner drives the outflow air flow to the first side of the blade 1 and contacts the left side piece 11 and the right side piece 12 respectively to form reflection, thereby changing the direction of the outflow air flow and achieving the soft wind outflow effect of non-direct blowing.

[0064] In a preferred embodiment,

[0065] The first side of the left side piece 11 is pivotally connected with the first side of the right side piece 12, which can be achieved by setting a rotating shaft, or by setting a corresponding shaft structure and hook structure on the first side of the left side piece 11 and the right side piece 12 respectively to form the pivotally connection. The vane 1 also has a closed state in which the left side piece 11 and the right side piece 12 are oppositely buckled. When the air conditioner in which the soft wind device is applied is not running in the soft wind mode, the vane 1 is in the closed state.

[0066] In the technical solution, the pivotally connection between the left side piece 11 and the right side piece 12 makes the vane 1 have an open state and a closed state. When the air conditioner is running in the soft wind mode, the vane 1 is controlled to be in the open state to ensure the soft wind effect. When the air conditioner is not running in the soft wind mode, for example, in the traditional air outlet mode, the vane 1 can be controlled to be in the closed state to ensure the air outlet volume, thereby ensuring the high efficiency of temperature adjustment.

[0067] Referring to Figure 1 and Figure 2 In some embodiments, the soft wind device further comprises:

[0068] A first opening and closing driving assembly 2 comprising a first driving strip 21 and a first rotary motor 22. The first driving strip 21 comprises a first meshing driving section 211 and a first vane connecting section 212. The first meshing driving section 211 is meshingly connected with the rotating shaft gear of the first rotary motor 22. The first vane connecting section 212 is connected with the right side piece 12 of each vane 1 in the first soft wind vane group.

[0069] A second opening and closing driving assembly 3 comprising a second driving strip 31 and a second rotary motor 32. The second driving strip 31 comprises a second meshing driving section and a second vane connecting section. The second meshing driving section is meshingly connected with the rotating shaft gear of the second rotary motor 32. The second vane connecting section is connected with the left side piece 11 of each vane 1 in the first soft wind vane group. The first meshing driving section 211 and the second meshing driving section are specifically a belt section having a hollow hole at one end. Each hollow hole corresponds to a tooth of a rotating shaft gear.

[0070] In the technical solution, the left side piece 11 and the right side piece 12 can be connected with the first vane connecting section 212 and the second vane connecting section respectively. When it is necessary to switch the state of the vane 1, the rotating direction of the first rotary motor 22 and the second rotary motor 32 is controlled, thereby driving the first driving strip 21 and the second driving strip 31 to move in the first direction, so as to drive the size of the included angle between the left side piece 11 and the right side piece 12, thereby controlling the switching of the vane 1 between the open state and the closed state.

[0071] In a specific embodiment, the relative opening angle between the left blade 11 and the right blade 12 ranges from 0° to 45°. It can be understood that the opening angle is 0°, i.e. the blade 1 is in a closed state, and the maximum opening angle is 45°. The opening angle can reduce the adverse reduction of the air volume on the premise of changing the air direction. See Figure 3 As shown, 2α in the figure refers to the maximum opening angle of the blade 1. In a specific embodiment, the clamping surface of the left blade 11 and the right blade 12 is perpendicular to the first direction (in the orientation shown). Figure 3

[0072] In some embodiments, the soft wind device further comprises:

[0073] The first wind sweeping driving assembly 4 comprises a first wind sweeping driving member 41 and a first wind sweeping connecting rod 42 fixedly connected with the first side of each blade 1 in the first soft wind blade group. The first wind sweeping driving member 41 can drive the first wind sweeping connecting rod 42 to move linearly in the first direction. The first wind sweeping connecting rod 42 is made of a material with high structural rigidity, which can be driven by the first wind sweeping driving member 41 to move linearly in the first direction. In the assembly of the air conditioner, the linear movement of the first wind sweeping connecting rod 42 can be guided by the corresponding slide rail. At this time, each blade 1 in the first soft wind blade group is finally positioned on the first wind sweeping connecting rod 42. The first wind sweeping driving member 41 can be a rotary motor with a gear on the output end. The first wind sweeping connecting rod 42 has a corresponding rack structure. The rack structure is engaged with the gear. The forward and reverse rotation of the rotary motor realizes the connection of the first wind sweeping connecting rod 42. Of course, other feasible structures can also be used, such as a cam structure to drive the reciprocating movement of the first wind sweeping connecting rod 42. The specific implementation form of the first wind sweeping driving member 41 is not described herein.

[0074] In the technical solution, the first wind sweeping driving assembly 4 drives the left and right swinging of each blade 1 in the first soft wind blade group to realize the air sweeping effect. When the soft wind effect is not needed, the air volume is ensured to be large, and the temperature of the temperature adjustment space is more uniform.

[0075] See Figure 1 ​As shown, in some embodiments, the soft wind device further comprises a second soft wind blade group (not labeled in the figure) which has the same structure as the first soft wind blade group, i.e. the second soft wind blade group is provided with a plurality of blades 1 which are spaced along the first direction, the number and structure of the blades 1 in the two soft wind blade groups are the same, and the blades 1 are arranged in front of and behind each other along the direction of the airflow outflow, for example, the first soft wind blade group is upstream of the air outflow, and the second soft wind blade group is downstream of the air outflow, or vice versa, and each of the blades 1 in the second soft wind blade group is located between two adjacent blades 1 in the first soft wind blade group.

[0076] In the technical solution, each blade 1 in the two soft wind blade groups is formed in a staggered manner, when the second soft wind blade group is upstream of the first soft wind blade group, referring to Figure 3 As shown, the air outflow first contacts and reflects each blade 1 in the second soft wind blade group to change the flow direction, and then the airflow partially changing the flow direction contacts and reflects each blade 1 in the first soft wind blade group again, so that the direction of the air outflow is more, and the soft wind effect is better.

[0077] In some embodiments,

[0078] The first driving strip 21 further comprises a third blade connecting segment 213 which is respectively arranged at both ends of the first meshing driving segment 211 with the first blade connecting segment 212, and the third blade connecting segment 213 is connected with the left side piece 11 of each blade 1 in the second soft wind blade group; or, the second driving strip 31 further comprises a fourth blade connecting segment which is respectively arranged at both ends of the second meshing driving segment with the second blade connecting segment, and the fourth blade connecting segment is connected with the right side piece 12 of each blade 1 in the second soft wind blade group.

[0079] In the technical solution, the first driving strip 21 and the second driving strip 31 drive the state switching of each blade 1 in the second soft wind blade group at the same time when driving the state switching of each blade 1 in the first soft wind blade group, which simplifies the design of the driving structure and reduces the manufacturing cost. The first driving strip 21 and the second driving strip 31 described above should be made of a material which has a certain rigidity and can be deformed.

[0080] In some embodiments, the soft wind device further comprises:

[0081] A second air-sweeping driving assembly 5 includes a second air-sweeping driving member 51 and a second air-sweeping connecting rod 52 fixedly connected with the first side of each blade 1 in the second group of soft air blades, and the second air-sweeping driving member 51 can drive the second air-sweeping connecting rod 52 to move linearly back and forth along the first direction. The design purpose is the same as that of the first air-sweeping driving assembly 4, which will not be described here.

[0082] According to the embodiment of the present application, an air conditioner is also provided, which includes the soft air device 10 described above. Specifically, as shown in Figure 4 The first air-sweeping driving member 41, the second air-sweeping driving member 51, the first rotary motor 22 and the second rotary motor 32 are fixedly connected to the shell of the air conditioner, and the corresponding first group of soft air blades and the second group of soft air blades are located in the air outlet air duct 20. Correspondingly, a small air deflector 30 that can be opened and closed is arranged at the air outlet of the air outlet air duct 20, and a large air deflector is arranged adjacent to the small air deflector 30. The soft air device 10 is arranged in the air outlet air duct 20, that is, hidden in the air outlet air duct 20, and the arrangement does not reduce the aesthetic appearance of the air conditioner. At the same time, each blade 1 interferes with the air flow in the air outlet air duct 20, and the air flow blown out by the air outlet air duct 20 is reflected by the blades 1 and blown to the indoor in multiple directions, improving the comfort of the user.

[0083] According to the embodiment of the present application, a control method of the air conditioner described above is also provided, which includes the following steps:

[0084] Obtaining the operation mode of the air conditioner, the operation mode including a soft air mode and a non-soft air mode;

[0085] Controlling the blades 1 to switch between the open state and the closed state according to the obtained operation mode.

[0086] In the technical solution, the state of the blades 1 is controlled according to different operation modes, which can achieve the switching purpose of the soft air effect and the large air volume outflow.

[0087] In some embodiments,

[0088] When the operation mode is the soft air mode, the blades 1 in the first group of soft air blades and the second group of soft air blades are controlled to be in the open state, so that each blade 1 forms a barrier to the air flow and changes the air flow to form a soft air effect. When the operation mode is not the soft air mode (i.e., the non-soft air mode), the blades 1 in the first group of soft air blades and the second group of soft air blades are controlled to be in the closed state. It should be noted that the non-soft air mode is each mode other than the soft air mode, that is, other modes that do not need to change the direction of the air flow, including when the air conditioner is turned off, the blades 1 are also controlled to be in the closed state.

[0089] In some embodiments,

[0090] When the operation mode is the soft wind mode, controlling the blades 1 in the first soft wind blade group and the second soft wind blade group to be in the open state specifically includes: controlling the first rotary motor 22 to operate in a first rotation direction, controlling the second rotary motor 32 to operate in a second rotation direction, and stopping operation after each blade 1 is opened to a preset angle, the first rotation direction being opposite to the second rotation direction; when the operation mode is not the soft wind mode, controlling the blades 1 in the first soft wind blade group and the second soft wind blade group to be in the closed state specifically includes: controlling the first rotary motor 22 to operate in the second rotation direction, controlling the second rotary motor 32 to operate in the first rotation direction, and stopping operation after each blade 1 is switched to the closed state. When the first rotation direction is clockwise, the second rotation direction is counterclockwise.

[0091] In some embodiments, when the operation mode is not the soft wind mode and includes a sweeping wind requirement, the first sweeping wind driving assembly 4 and / or the second sweeping wind driving assembly 5 is also controlled to operate. That is, when the user has a sweeping wind requirement, the sweeping wind driving assembly is controlled to operate to realize sweeping wind of the blades 1.

[0092] In a preferred embodiment, when the air conditioner detects that there is a person in the room, the soft wind mode is operated, and when the air conditioner detects that there is no person in the room, the soft wind mode is exited. Specifically, a radar detection device is arranged in the air conditioner, which detects whether there is a person in the room, and when a person is detected, the soft wind mode is operated to improve the user experience, and when no person is detected, the soft wind mode is exited, thereby ensuring rapid temperature adjustment of the indoor space. At this time, it can be understood that when the soft wind mode is exited, the blades 1 are controlled to be in the closed state.

[0093] Specifically in combination Figure 5 with the control method of the present application is described as follows:

[0094] As Figure 4 shown, when the air conditioner is turned off, the soft wind device blade group is located at the initial position and is in the closed state,

[0095] 1. When the air conditioner is turned on, the air conditioner detects whether there is a user in the room through the radar;

[0096] Yes→ turn on the soft wind mode; No→ air conditioner normal operation (i.e., non-soft wind mode). The user can also manually control the air conditioner to turn on the soft wind mode or the normal operation mode.

[0097] 2. When the gentle breeze mode is activated, the control linkage assembly motor (i.e., the first sweeping drive component 41 and the second sweeping drive component 51 mentioned above, hereinafter the same) does not operate, the linkage (i.e., the first sweeping connecting rod 42 and the second sweeping connecting rod 52 mentioned above, hereinafter the same) is fixed, and the blade rotation axis (i.e., the pivot position of the first side of the blade mentioned above, hereinafter the same) is fixed; the control gear assembly motor (i.e., the first rotary motor 22 and the second rotary motor 32 mentioned above, hereinafter the same) operates, and the gear assembly chains 1 and 2 (i.e., the first drive bar 21 and the second drive bar 31 mentioned above, hereinafter the same) drive the left blade (i.e., the left side blade 11 mentioned above, hereinafter the same) to rotate clockwise around the rotation axis, and the right blade (i.e., the right side blade 12 mentioned above, hereinafter the same) to rotate counterclockwise around the rotation axis. To ensure minimal airflow loss and achieve a gentle, windless effect, when the blade rotates around the rotation axis by an angle α, the motor stops operating, keeping the blade in its current position and state. At this time, the included angle between the two blades is 2α (e.g., ...). Figure 3 As shown), the blade rotation angle range is 0° < α < 22.5°. Airflow exits the duct, is reflected by the blades, and then blows out along the surface of the air guide plate, diffusing into the room in multiple directions. When the gentle breeze mode is off (i.e., exited) or the air conditioner is turned off, the control gear assembly motor reverses direction. The chains of gear assemblies 1 and 2 drive the left blade to rotate counter-clockwise around the rotation axis and the right blade to rotate clockwise around the rotation axis. When the air conditioner detects that the blades have returned to their initial position, the gear assembly motor stops running. At this time, the gentle breeze device is in its initial state (e.g., ...). Figure 2 (As shown).

[0098] 3. When the air conditioner is running normally, the blades are in the closed state, the gear assembly motor does not run, and the end of the blade connected to the gear assembly chain is fixed. The control linkage assembly motor runs, and the left and right movement of the linkage drives the blade assembly to swing left and right, so as to realize the sweeping or directional airflow.

[0099] When the normal operating mode is off or the air conditioner is turned off, the linkage drives the blade rotation shaft to swing to the initial position. When the air conditioner detects that the blade has returned to the initial position, the linkage assembly motor stops running, and the soft wind device is in the initial state.
