Description

Technical Field

[0001] This application relates to the field of soft wind technology, and particularly to soft wind components and air conditioners. Background Technology

[0002] An air conditioner is a household appliance used to deliver air to users, which improves the indoor temperature by blowing out air at different temperatures.

[0003] In related technologies, when the airflow generated by an air conditioner blows on the human body, it can cause discomfort to the user. Utility Model Content

[0004] In view of this, this application provides a gentle breeze component and an air conditioner to reduce user discomfort.

[0005] Specifically, the following technical solutions are included:

[0006] A first aspect of this application provides a gentle breeze assembly, the gentle breeze assembly comprising a housing and an air diffuser, wherein...

[0007] The housing includes a first sub-shell and a second sub-shell, with one side of the first sub-shell connected to one side of the second sub-shell, forming an installation space;

[0008] The air diffuser is installed within the installation space.

[0009] In some possible implementations, the housing has a major axis and a minor axis in its orthographic projection onto the projection plane, the major axis intersecting the minor axis, and the projection plane is a plane perpendicular to the flow direction of the airflow within the installation space.

[0010] With the above arrangement, since the housing is generally located at the air outlet of the air conditioner, this shape of housing 1 can improve the airflow performance and the air sweeping effect of the air conditioner. Among them, with the projected area of ​​the housing remaining unchanged, the greater the difference in length between the major axis and the minor axis, the more slender the overall shape of the housing, and the larger the range of air delivery angle.

[0011] In some possible implementations, the first sub-shell includes an inlet, and the second sub-shell includes an outlet, both of which communicate with the installation space. The area of ​​the inlet projected onto the projection plane is 50% to 80% of the area of ​​the first sub-shell projected onto the projection plane; and / or, the area of ​​the outlet projected onto the projection plane is 50% to 80% of the area of ​​the second sub-shell projected onto the projection plane. The projection plane is a plane perpendicular to the flow direction of the airflow within the installation space.

[0012] With the above arrangement, airflow can enter the installation space from the inlet, be blocked by the diffuser to change direction and reduce velocity, and then leave the installation space from the outlet. In this way, the airflow entering the room from the installation space can reduce discomfort when it blows on the human body.

[0013] In some possible implementations, the inlet includes a first inlet and a second inlet, wherein the orthographic projection of the first inlet onto the projection plane at least partially coincides with the orthographic projection of the air diffuser onto the projection plane, and the second inlet is distributed circumferentially around the first inlet; and / or, the outlet includes a first outlet and a second outlet, wherein the orthographic projection of the first outlet onto the projection plane at least partially coincides with the orthographic projection of the air diffuser onto the projection plane, and the second outlet is distributed circumferentially around the first outlet.

[0014] With the above arrangement, the first inlet allows airflow to enter the installation space and guides it to the diffuser, which helps the diffuser guide, disrupt, and block the airflow, thereby reducing its velocity. The second inlet also allows airflow to enter the installation space and increases the cavity area on the first sub-shell for airflow passage, reducing the excessive obstruction of the airflow by the first sub-shell's volume and thus minimizing kinetic energy loss. The first outlet allows airflow to leave the installation space. Due to the presence of the diffuser, the velocity and direction of the airflow leaving the installation space through the first outlet will change to some extent, reducing discomfort caused by the airflow blowing on the body. The second outlet also allows airflow guided, blocked, and disrupted by the diffuser to leave the installation space, and also increases the cavity area on the second sub-shell for airflow passage, reducing the excessive obstruction of the airflow by the second sub-shell's volume and thus minimizing kinetic energy loss.

[0015] In some possible implementations, the housing has a major axis and a minor axis in its orthographic projection onto the projection plane, the major axis intersecting the minor axis, wherein the number of second inlets is multiple, and the orthographic projections of the multiple second inlets onto the projection plane are distributed at both ends of the major axis; and / or, the number of second outlets is multiple, and the orthographic projections of the multiple second outlets onto the projection plane are distributed at both ends of the major axis.

[0016] Through the above arrangement, the number and area of ​​the second inlet can be changed according to actual needs, thereby adjusting the proportion of the area of ​​the inlet's orthographic projection on the projection plane to the area of ​​the first subshell's orthographic projection on the projection plane. A larger proportion of the second inlet results in higher ventilation efficiency and lower kinetic energy loss for the soft-air assembly, but also a worse effect of the diffuser in guiding, blocking, and disrupting airflow. Conversely, a smaller proportion of the second inlet results in lower ventilation efficiency and higher kinetic energy loss, but also a better effect of the soft-air assembly in guiding, blocking, and disrupting airflow. Similarly, the number and area of ​​the second outlet can be changed according to actual needs, thereby adjusting the proportion of the outlet's orthographic projection on the projection plane to the area of ​​the second subshell's orthographic projection on the projection plane. A larger proportion of the second outlet results in higher ventilation efficiency and lower kinetic energy loss for the soft-air assembly, but also a worse effect of the diffuser in guiding, blocking, and disrupting airflow. Conversely, a smaller proportion of the second outlet results in lower ventilation efficiency and higher kinetic energy loss, but also a better effect of the soft-air assembly in guiding, blocking, and disrupting airflow.

[0017] In some possible implementations, the air diffuser includes blades and a support shaft, one end of the blades is connected to the shaft of the support shaft, the other end of the blades is an open end, one end of the support shaft is connected to the first sub-shell, the other end is connected to the second sub-shell, and the support shaft is rotatable relative to the first sub-shell and the second sub-shell.

[0018] With the above arrangement, the support shaft can drive the blades to rotate under the blowing of airflow, which helps to reduce the kinetic energy loss from the diffuser. The other end of the blade is an open end, which can avoid interference between the blade and the first or second sub-shell when the blade rotates. The blade can also guide, disrupt, and block the airflow entering the installation space, thus reducing the wind speed when the airflow leaves the installation space.

[0019] In some possible implementations, the first sub-shell includes a first mounting hole, the second sub-shell includes a second mounting hole, the first mounting hole and the second mounting hole are disposed opposite to each other along the flow direction of the airflow, one end of the support shaft extends into the first mounting hole and the other end extends into the second mounting hole.

[0020] With the above arrangement, the first and second mounting holes, by contacting the two ends of the support shaft respectively, can support the two ends of the support shaft and balance the weight of the support shaft. The first and second mounting holes can also allow the support shaft to rotate. Since the first and second mounting holes are arranged opposite each other along the airflow direction, when the blades obstruct the airflow, the reaction force on the blades will act on the shaft body of the support shaft. Because the direction of the reaction force is generally along the tangent of the support shaft, the diffuser will rotate under the impetus of the airflow.

[0021] In some possible implementations, the number of blades is multiple, and the multiple blades are arranged circumferentially at intervals along the support shaft. Each blade is radially twisted along the support shaft, and the twisting directions of adjacent blades are the same or opposite.

[0022] With the above arrangement, multiple blades can generate reaction forces at different positions on the support shaft when obstructing airflow, thus pushing the support shaft to rotate. These multiple reaction forces acting on the support shaft facilitate its rotation. The rotating support shaft also drives the blades to continuously guide, disrupt, and obstruct airflow at different positions, thereby improving the airflow disruption effect of the soft-wind assembly.

[0023] In some possible implementations, the diameter of the support shaft ranges from 1 to 10 mm, and the ratio of the maximum width of the air diffuser to the diameter of the support shaft ranges from 10 to 30.

[0024] With the above arrangement, using a support shaft with a diameter within the aforementioned range helps reduce the kinetic energy loss of the airflow caused by the support shaft itself. It also helps provide sufficient support force for the blades to maintain their attitude stability. Using the above-mentioned range for the ratio of the maximum width W of the diffuser to the diameter of the support shaft allows for a sufficiently large blade structure with adequate width, length, and thickness, thus improving the blade's guiding effect on the airflow. The installation angle of the above embodiment helps optimize the airflow path, thereby reducing the impact of the blade shape on the kinetic energy loss of the airflow.

[0025] In some possible implementations, the installation angle of the blade ranges from 10° to 75°.

[0026] With the above arrangement, within the above value range, the windward area of ​​the blades to the airflow is within a suitable range, which is conducive to the blades guiding the airflow with sufficient flow. At the same time, the impact of the airflow on the blades is also within the acceptable range of the blades, which helps to reduce the situation where the blades break due to the impact of the airflow.

[0027] In some possible implementations, the soft wind assembly includes a drive structure that is tractively connected to the housing for driving the housing to rotate about a first axis that intersects the flow direction of the airflow in the installation space.

[0028] With the above arrangement, when the air volume and air speed requirements are large, the shell can be rotated to change its orientation and adjust its wind-softening effect. Since the first axis intersects with the airflow direction in the installation space, and the airflow needs to pass through the installation space to be guided, disrupted, and blocked by the diffuser, the difficulty of the airflow entering the installation space increases after the shell orientation is changed. This helps to reduce the kinetic energy loss caused by the airflow passing through the wind-softening component.

[0029] In some possible implementations, the drive structure includes a motor and a transmission component, the transmission component drivingly connecting the motor and the housing, and the motor driving the housing to rotate about the first axis through the transmission component.

[0030] With the above arrangement, the motor can generate driving force by rotating. Under the adjustment of the transmission components, the driving force is output to the housing, which can make the housing rotate. Since the air diffuser is connected to the housing, the orientation of the air diffuser connected to the housing can be changed.

[0031] In some possible implementations, the drive structure includes a rotating shaft, one end of which is connected to one side of the first sub-shell or one side of the second sub-shell. The axis of the rotating shaft is a first axis. The transmission component includes a first connecting rod and a second connecting rod. A first end of the first connecting rod is connected to one end of the rotating shaft, and a second end of the first connecting rod is hinged to the second connecting rod. The motor is driven by the second connecting rod to drive the second connecting rod to oscillate around the axis of the rotating shaft. Alternatively, the transmission component includes a rack and a gear. The rack meshes with the gear, and the motor is driven by the rack to drive the rack to move along the tangential direction of the gear. The other end of the rotating shaft is driven by the gear.

[0032] With the above arrangement, when the second link swings, it can cause the first end of the first link to swing accordingly. Since the second end of the first link is connected to one end of the rotating shaft, when the first segment of the first link swings around the axis of the rotating shaft, the second end of the first link can rotate around the axis of the rotating shaft. This can cause the housing connected to the rotating shaft to rotate around the first axis. When the rack moves, it meshes with the gear, thus causing the gear to rotate. The rotating gear will then cause the rotating shaft connected to it to rotate around the first axis. This can change the orientation of the housing, thereby adjusting the gentle breeze effect of the gentle breeze assembly.

[0033] In some possible implementations, the soft wind assembly includes a mounting base, and the number of housings is multiple, each housing having an air diffuser within its mounting space, with the multiple housings spaced apart along the length of the mounting base.

[0034] With the above arrangement, since the air outlet of an air conditioner is generally elongated, multiple housings of the wind-blowing assembly can be arranged on the air outlet via the mounting bracket. This helps to improve the effect of the wind-blowing assembly in blocking and disrupting the airflow blown out by the air conditioner. At the same time, the mounting bracket can also be used to connect the wind-blowing assembly to the air conditioner.

[0035] In some possible implementations, the soft wind assembly includes an air guide plate, and the housing is mounted on one side of the air guide plate.

[0036] With the above arrangement, the air guide plate can be directly installed on the air conditioner as part of the air conditioner during the assembly process, without the need to add other components to the air conditioner. This can reduce the complexity of the soft wind component assembly process.

[0037] A second aspect of this application provides an air conditioner that includes a gentle breeze component as described in the above technical solutions.

[0038] In some possible implementations, the air conditioner includes a main body, and the number of wind-softening components is multiple, with the multiple wind-softening components installed at the air outlet of the main body.

[0039] With the above arrangement, multiple gentle breeze components can create a gentle breeze effect at different positions of the air outlet of the main body, reducing the situation where airflow directly blows onto the human body through the air outlet.

[0040] In some possible implementations, multiple soft wind components are arranged to form two groups, with both groups of soft wind components spaced apart along the length of the air outlet of the body, wherein the two groups of soft wind components are used to guide the airflow to the same side or opposite side of the body.

[0041] With the above arrangement, the air conditioning unit can guide the airflow from the air conditioner to the same side of the unit, increasing the independence of the airflow passing through different air conditioning units and reducing mutual interference caused by the intersection of flow paths. Alternatively, the air conditioner can guide the airflow from different positions of the air outlet outward along its original flow path, thereby expanding the airflow range. Or, the air conditioner can guide the airflow from different air conditioning units to the same position, causing the airflow paths to intersect and thus reducing mutual interference. The velocity of the interfering airflow is reduced, which helps to alleviate the user's discomfort when being blown by the air.

[0042] The beneficial effects of the technical solution provided in this application embodiment include at least the following: the first sub-shell and the second sub-shell form an installation space, which can accommodate the air diffuser and support the air diffuser. At the same time, the installation space allows the airflow blown out by the air conditioner to pass through and be guided and disrupted by the air diffuser. When the disrupted airflow blows on the user's body, the flow rate and air volume are reduced, and the airflow is relatively dispersed, thus reducing the user's discomfort.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0062] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0063] In the embodiments of this application, directional terms such as "upper," "lower," and "side" are generally used in the following ways: Figure 1 The relative positions shown are based on the given information, and these directional terms are used only to more clearly describe the relationships between structures, not to describe absolute positions. Positions may change when the product is placed in different orientations; for example, "up" and "down" may be interchanged.

[0064] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0065] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0066] The first aspect of this application provides a gentle breeze component, such as Figure 1 and Figure 2 As shown, the gentle breeze assembly includes a housing 1 and an air diffuser 2, wherein,

[0067] The housing 1 includes a first sub-housing 11 and a second sub-housing 12. One side of the first sub-housing 11 is connected to one side of the second sub-housing 12, forming an installation space 100.

[0068] The air diffuser 2 is installed within the installation space 100.

[0069] With the above arrangement, the first sub-shell 11 and the second sub-shell 12 form an installation space 100, which can accommodate the air diffuser 2 and provide support for it. At the same time, the installation space 100 allows the airflow blown out by the air conditioner to pass through and be guided and disrupted by the air diffuser 2. When the disrupted airflow blows on the user's body, the flow rate and volume are reduced, and the airflow is relatively dispersed, thus reducing the user's discomfort.

[0070] In this embodiment, the air diffuser 2 can block the airflow generated by the air conditioner through its own structural characteristics, thereby changing the direction of airflow and reducing the airflow speed and volume.

[0071] In this embodiment, the gentle breeze component can be installed at the air outlet of the air conditioner, located in the direction of airflow, thus guiding and disrupting the airflow. Furthermore, since the airflow direction generated by an air conditioner is generally relatively fixed, blowing from top to bottom or horizontally, the disrupting effect of the gentle breeze component helps to direct some airflow in other directions, thereby improving the uniformity of airflow within the room and enhancing the uniformity of indoor temperature distribution.

[0072] In this embodiment of the application, the portions of the first sub-shell 11 and the second sub-shell 12 that are opposite to each other are recessed inward, so that when they are connected on one side, they can form an installation space 100.

[0073] In this embodiment, one side of the first sub-shell 11 and one side of the second sub-shell 12 are connected by fastening or by ultrasonic welding.

[0074] In some embodiments of this application, such as Figure 3 As shown, the orthographic projection of the housing 1 onto the projection plane has a major axis and a minor axis, which intersect. The projection plane is a plane perpendicular to the flow direction of the airflow within the installation space 100.

[0075] With the above arrangement, since the housing 1 is generally located at the air outlet of the air conditioner, this shape of housing 1 can improve the airflow performance and the air sweeping effect of the air conditioner. Among them, with the projected area of ​​the housing remaining unchanged, the greater the difference in length between the major axis and the minor axis, the more slender the overall shape of the housing 1, and the larger the range of air delivery angle.

[0076] In the embodiments of this application, when the length of the long shaft is 35mm, the air delivery angle of the soft wind assembly is in the range of 20°; when the length of the long shaft is 50mm, the air delivery angle of the soft wind assembly is in the range of 25°.

[0077] In this embodiment of the application, the orthographic projection of the housing 1 onto the projection plane can be elliptical.

[0078] In some embodiments of this application, such as Figure 1 As shown, the first sub-shell 11 includes an inlet 111, and the second sub-shell 12 includes an outlet 121. Both the inlet 111 and the outlet 121 are connected to the installation space 100. The area of ​​the orthographic projection of the inlet 111 onto the projection plane accounts for 50% to 80% of the area of ​​the orthographic projection of the first sub-shell 11 onto the projection plane. The projection plane is a plane perpendicular to the flow direction of the airflow within the installation space 100.

[0079] With the above arrangement, the airflow can enter the installation space 100 from the inlet 111, and be blocked by the diffuser 2 to change direction and reduce the flow rate, and then leave the installation space 100 from the outlet 121. In this way, the airflow entering the room from the installation space 100 can reduce the discomfort of the human body when it blows on the human body.

[0080] Meanwhile, due to the obstruction effect of the soft wind component, the airflow blown out by the air conditioner will have a certain kinetic energy loss when passing through the soft wind component. In order to reduce the impact of this kinetic energy loss on the performance of the air conditioner, the area of ​​the inlet 111 projected onto the projection plane can be set to account for 50% to 80% of the area of ​​the first sub-shell 11 projected onto the projection plane. This will not only help improve the airflow efficiency of the soft wind component, but also reduce the kinetic energy loss of the airflow caused by the structure of the soft wind component itself.

[0081] In the embodiments of this application, the area ratio of the orthographic projection of the entrance 111 to the orthographic projection of the first subshell 11 can be 50%, 55%, 60%, 65%, 70%, 75% or 80%, or other values ​​between 50% and 80%.

[0082] In some embodiments of this application, such as Figure 1 As shown, the second sub-shell 12 includes an outlet 121, and both the inlet 111 and the outlet 121 are connected to the installation space 100. The area of ​​the outlet 121 projected onto the projection plane accounts for 50% to 80% of the area of ​​the second sub-shell 12 projected onto the projection plane. The projection plane is a plane perpendicular to the flow direction of the airflow in the installation space 100.

[0083] With the above arrangement, the airflow can enter the installation space 100 from the inlet 111, and be blocked by the diffuser 2 to change direction and reduce the flow rate, and then leave the installation space 100 from the outlet 121. In this way, the airflow entering the room from the installation space 100 can reduce the discomfort of the human body when it blows on the human body.

[0084] In this embodiment of the application, the area of ​​the orthographic projection of the entrance 111 onto the projection plane accounts for 50% to 80% of the area of ​​the orthographic projection of the first subshell 11 onto the projection plane.

[0085] In the embodiments of this application, the area ratio of the orthographic projection of the outlet 121 to the orthographic projection of the second subshell 12 can be 50%, 55%, 60%, 65%, 70%, 75% or 80%, or other values ​​between 50% and 80%.

[0086] In some embodiments of this application, such as Figure 1As shown, the inlet 111 includes a first inlet 1111 and a second inlet 1112. The orthographic projection of the first inlet 1111 on the projection plane at least partially coincides with the orthographic projection of the air diffuser 2 on the projection plane. The second inlet 1112 is distributed around the first inlet 1111.

[0087] With the above arrangement, the first inlet 1111 allows airflow to enter the installation space 100 and guides the airflow to the diffuser 2. This helps the diffuser 2 to guide, disrupt, and block the airflow, thereby reducing its velocity. Similarly, the second inlet 1112 allows airflow to enter the installation space 100 and also increases the cavity area on the first sub-shell 11 for airflow passage, thus reducing the excessive obstruction of the airflow by the volume of the first sub-shell 11 itself and increasing the kinetic energy loss of the airflow.

[0088] In this embodiment of the application, the area of ​​the first inlet 1111 can be larger than the area of ​​the second inlet 1112. There can be multiple first inlets 1111 and multiple second inlets 1112, and the sum of the areas of the first inlets 1111 is greater than the sum of the areas of the second inlets 1112.

[0089] In some embodiments of this application, such as Figure 1 As shown, outlet 121 includes a first outlet 1211 and a second outlet 1212. The orthographic projection of the first outlet 1211 on the projection plane at least partially coincides with the orthographic projection of the air diffuser 2 on the projection plane. The second outlet 1212 is distributed around the first outlet 1211.

[0090] With the above arrangement, the first outlet 1211 allows airflow within the installation space 100 to exit. Due to the presence of the air diffuser 2 within the installation space 100, the velocity and direction of the airflow leaving the installation space 100 through the first outlet 1211 will change to some extent, thus reducing discomfort caused by the airflow blowing on the human body. The second outlet 1212 also allows airflow guided, blocked, and disrupted by the air diffuser 2 to exit the installation space 100. It also helps to increase the cavity area on the second sub-shell 12 for airflow passage, thereby reducing excessive obstruction of the airflow by the volume of the second sub-shell 12 itself and increasing the kinetic energy loss of the airflow.

[0091] In this embodiment of the application, the area of ​​the first outlet 1211 can be larger than the area of ​​the second outlet 1212. There can be multiple first outlets 1211 and multiple second outlets 1212, and the sum of the areas of the first outlets 1211 is greater than the sum of the areas of the second outlets 1212.

[0092] In this embodiment of the application, the inlet 111 includes a first inlet 1111 and a second inlet 1112. The orthographic projection of the first inlet 1111 on the projection plane at least partially overlaps with the orthographic projection of the air diffuser 2 on the projection plane. The second inlet 1112 is distributed around the first inlet 1111.

[0093] In some embodiments of this application, such as Figure 1 As shown, the orthographic projection of the housing 1 onto the projection plane has a major axis and a minor axis, which intersect. There are multiple second inlets 1112, and the orthographic projections of the multiple second inlets 1112 onto the projection plane are distributed at both ends of the major axis.

[0094] Through the above arrangement, the number and area of ​​the second inlet 1112 can be changed according to actual needs, thereby adjusting the proportion of the area of ​​the second inlet 1112 projected onto the projection plane to the area of ​​the first subshell 11 projected onto the projection plane. The larger the proportion of the second inlet 1112, the higher the ventilation efficiency of the soft wind assembly and the smaller the kinetic energy loss. Correspondingly, the effect of the air diffuser 2 in guiding, blocking and disrupting the airflow is also worse. The smaller the proportion of the second inlet 1112, the lower the ventilation efficiency and the greater the kinetic energy loss. Correspondingly, the effect of the soft wind assembly in guiding, blocking and disrupting the airflow is also better.

[0095] In this embodiment of the application, the orthographic projection of the housing 1 onto the projection plane is elliptical. Therefore, the major axis of the orthographic projection of the housing 1 can refer to the axis passing through the two foci on the ellipse, and the minor axis and the perpendicular bisector of the major axis are collinear.

[0096] In some embodiments of this application, such as Figure 1 As shown, the orthographic projection of the housing 1 onto the projection plane has a major axis and a minor axis, which intersect. There are multiple second outlets 1212, and the orthographic projections of the multiple second outlets 1212 onto the projection plane are distributed at both ends of the major axis.

[0097] Through the above arrangement, the number and area of ​​the second outlet 1212 can be changed according to actual needs, thereby adjusting the proportion of the area of ​​the orthographic projection of outlet 121 on the projection plane to the area of ​​the orthographic projection of the second sub-shell 12 on the projection plane. The larger the proportion of the second outlet 1212, the higher the ventilation efficiency of the soft wind assembly and the smaller the kinetic energy loss. Correspondingly, the effect of the air diffuser 2 in guiding, blocking, and disrupting the airflow is also worse. The smaller the proportion of the second outlet 1212, the lower the ventilation efficiency and the greater the kinetic energy loss. Correspondingly, the effect of the soft wind assembly in guiding, blocking, and disrupting the airflow is also better.

[0098] In this embodiment of the application, there are multiple second outlets 1212, which are distributed at both ends of the major axis of the orthographic projection of the housing 1.

[0099] In this embodiment of the application, the orthographic projection of the housing 1 onto the projection plane is elliptical. Therefore, the major axis of the orthographic projection of the housing 1 can refer to the axis passing through the two foci on the ellipse, and the minor axis and the perpendicular bisector of the major axis are collinear.

[0100] In this embodiment of the application, there are multiple second inlets 1112, and the orthographic projections of the multiple second inlets 1112 on the projection plane are distributed at both ends of the major axis.

[0101] In some embodiments of this application, such as Figure 2 As shown, the air diffuser 2 includes blades 21 and a support shaft 22. One end of the blades 21 is connected to the shaft of the support shaft 22, and the other end of the blades 21 is an open end. One end of the support shaft 22 is connected to the first sub-shell 11, and the other end is connected to the second sub-shell 12. The support shaft 22 can rotate relative to the first sub-shell 11 and the second sub-shell 12.

[0102] With the above arrangement, under the blowing of the airflow, the support shaft 22 can drive the blades 21 to rotate, which helps to reduce the kinetic energy loss caused by the diffuser 2. The other end of the blades 21 is an open end, which can avoid interference between the blades 21 and the first sub-shell 11 or the second sub-shell 12 when the blades 21 rotate. The blades 21 can also guide, disrupt and block the airflow entering the installation space 100, thus reducing the wind speed when the airflow leaves the installation space 100.

[0103] In some embodiments of this application, such as Figure 2 As shown, the first sub-shell 11 includes a first mounting hole 1101, and the second sub-shell 12 includes a second mounting hole 1201. The first mounting hole 1101 and the second mounting hole 1201 are arranged opposite to each other along the airflow direction. One end of the support shaft 22 extends into the first mounting hole 1101, and the other end extends into the second mounting hole 1201.

[0104] With the above arrangement, the first mounting hole 1101 and the second mounting hole 1201, by contacting the two ends of the support shaft 22 respectively, can support the two ends of the support shaft 22 and balance the gravity acting on the support shaft 22. The first mounting hole 1101 and the second mounting hole 1201 can also allow the support shaft 22 to rotate. Since the first mounting hole 1101 and the second mounting hole 1201 are arranged opposite each other along the airflow direction, when the blade 21 obstructs the airflow, the reaction force on the blade 21 will act on the shaft of the support shaft 22. Since the direction of the reaction force is generally along the tangent direction of the support shaft 22, the air diffuser 2 will rotate under the push of the airflow.

[0105] In some embodiments of this application, such as Figure 1As shown, there are multiple blades 21, which are arranged circumferentially along the support shaft 22. Each blade 21 is twisted radially along the support shaft 22, and adjacent blades 21 twist in the same direction.

[0106] With the above arrangement, multiple blades 21 can generate reaction forces at different positions on the support shaft 22 when blocking airflow, thus promoting the rotation of the support shaft 22. The multiple reaction forces acting on the support shaft 22 are beneficial to promoting the rotation of the support shaft 22. The rotating support shaft 22 can also drive the blades 21 to continuously guide, disrupt, and block airflow at different positions, thereby improving the airflow disruption effect of the soft wind assembly.

[0107] In the embodiments of this application, the number of blades 21 can be 2, 3, 4 or 5, or other numbers.

[0108] In some embodiments of this application, there are multiple blades 21, which are arranged circumferentially along the support shaft 22. Each blade 21 is twisted radially along the support shaft 22, and adjacent blades 21 are twisted in opposite directions.

[0109] With the above arrangement, multiple blades 21 can generate reaction forces at different positions on the support shaft 22 when obstructing airflow, thus pushing the support shaft 22 to rotate. These multiple reaction forces acting on the support shaft 22 facilitate its rotation. The rotating support shaft 22 also drives the blades 21 to continuously guide, disrupt, and obstruct airflow at different positions, thereby improving the disrupting effect of the soft-wind assembly. Simultaneously, two blades 21 with opposite twisting directions can guide two airflows to the same position, causing them to converge and disrupt each other, further reducing wind speed.

[0110] In some embodiments of this application, such as Figure 2 As shown, the diameter of the support shaft 22 ranges from 1 to 10 mm, and the ratio of the maximum width W of the air diffuser 2 to the diameter of the support shaft 22 ranges from 10 to 30.

[0111] With the above arrangement, the support shaft 22, with its diameter within the aforementioned range, helps to reduce the kinetic energy loss caused by the support shaft 22 itself to the airflow. It also helps to provide sufficient support for the blades 21 to maintain their attitude stability. The ratio of the maximum width W of the diffuser section 2 to the diameter of the support shaft 22, within the aforementioned range, allows the blades 21 to have a sufficiently large structure with adequate width, length, and thickness, thus improving the guiding effect of the blades 21 on the airflow.

[0112] In the embodiments of this application, the maximum width W of the air diffuser 2 can refer to: for an air diffuser 2 with a shape similar to a circle, the maximum width W can refer to the maximum diameter of the air diffuser 2; for an air diffuser 2 with an irregular shape, the maximum distance between two points on the edge of the air diffuser 2 can be taken as the maximum width W.

[0113] In this embodiment, the diameter of the support shaft 22 can be 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm or 10mm, or other values ​​from 1 to 10mm.

[0114] In the embodiments of this application, the ratio of the maximum width W of the air diffuser 2 to the diameter of the support shaft 22 can be 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29 or 30, or other values ​​from 10 to 30.

[0115] In some embodiments of this application, the installation angle A of the blade 21 ranges from 10° to 75°.

[0116] With the above arrangement, within the above value range, the windward area of ​​blade 21 to the airflow is within a suitable range, which is conducive to blade 21 guiding the airflow with sufficient flow. At the same time, the impact of the airflow on blade 21 is also within the acceptable range of blade 21, which helps to reduce the possibility of blade 21 breaking due to the impact of the airflow.

[0117] In the embodiments of this application, the installation angle A of the blade 21 can be 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70° or 75°, or other values ​​from 10° to 75°.

[0118] In the embodiments of this application, such as Figure 10 As shown, the installation angle A can refer to the angle formed between one side of the blade 21 connected to the support shaft 22 and the end face of the support shaft 22.

[0119] In the embodiments of this application, such as Figure 10 As shown, the installation angle A can refer to the angle formed between the side of the blade 21 away from the support shaft 22 and the end face of the support shaft 22.

[0120] In some embodiments of this application, such as Figure 4 As shown, the soft wind assembly includes a drive structure 3, which is connected to the housing 1 for driving the housing 1 to rotate around a first axis, which intersects the flow direction of the airflow in the installation space 100.

[0121] With the above arrangement, when the air volume and air speed requirements are large, the housing 1 can be rotated to change its orientation and adjust its wind-softening effect. Since the first axis intersects with the airflow direction in the installation space 100, and the airflow needs to pass through the installation space 100 to be guided, disrupted, and blocked by the diffuser 2, the difficulty of the airflow entering the installation space 100 increases after the orientation of the housing 1 is changed. This helps to reduce the kinetic energy loss caused by the airflow passing through the wind-softening component.

[0122] In the embodiments of this application, when the demand for air volume and air speed is large, such as Figure 6 As shown, when the gentle breeze component is rotated to the orientation shown in the figure, the airflow from the air conditioner is less obstructed, which can meet the user's needs.

[0123] In the embodiments of this application, when the demand for air volume and air speed is relatively small, such as Figure 7 As shown, when the gentle breeze component is rotated to the orientation shown in the figure, the airflow from the air conditioner is more obstructed, which can meet the user's needs.

[0124] In some embodiments of this application, the drive structure 3 includes a motor and a transmission component 32. The transmission component 32 is connected to the motor and the housing 1. The motor drives the housing 1 to rotate around a first axis through the transmission component.

[0125] With the above arrangement, the motor can generate driving force by rotating. Under the adjustment of the transmission component 32, the driving force is output to the housing 1, which can make the housing 1 rotate. The air diffuser 2 is connected to the housing 1, so the orientation of the air diffuser 2 connected to the housing 1 can be changed.

[0126] In some embodiments of this application, such as Figure 5 As shown, the drive structure 3 includes a rotating shaft 31, one end of which is connected to one side of the first sub-shell 11 or one side of the second sub-shell 12. The axis of the rotating shaft 31 is a first axis.

[0127] The transmission component 32 includes a first link 321 and a second link 322. The first end of the first link 321 is connected to one end of the rotating shaft 31, and the second end of the first link 321 is hinged to the second link 322. The motor is connected to the second link 322 for driving the second link 322 to swing around the axis of the rotating shaft 31.

[0128] With the above arrangement, when the second link 322 swings, it can drive the first end of the first link 321 to swing accordingly. Since the second end of the first link 321 is connected to one end of the rotating shaft 31, when the first segment of the first link 321 swings around the axis of the rotating shaft 31, the second end of the first link 321 can rotate around the axis of the rotating shaft 31, thus driving the housing 1 connected to the rotating shaft 31 to rotate around the first axis.

[0129] In some embodiments of this application, such as Figure 4 As shown, the drive structure 3 includes a rotating shaft 31. One end of the rotating shaft 31 is connected to one side of the first sub-shell 11 or one side of the second sub-shell 12. The axis of the rotating shaft 31 is the first axis. The transmission component 32 includes a rack and a gear 331. The rack meshes with the gear 331. The motor is connected to the rack for driving the rack to move along the tangential direction of the gear 331. The other end of the rotating shaft 31 is connected to the gear 331 for transmission.

[0130] With the above arrangement, when the rack moves, it meshes with the gear 331, which in turn drives the gear 331 to rotate. The rotating gear 331 then drives the rotating shaft 31 connected to it to rotate around the first axis. This allows the orientation of the housing 1 to be changed, thereby adjusting the soft wind effect of the soft wind assembly.

[0131] In this embodiment, the gear 331 and the rotating shaft 31 can be connected by means of snap-fit, key connection or other means to achieve transmission.

[0132] In this embodiment, the rack can change the rotation direction of the gear 331 by changing its direction of movement. For example, as shown... Figure 4 As shown, when the rack moves to the left along the tangent of gear 331, gear 331 rotates counterclockwise, increasing the windward area of ​​housing 1 and enhancing its blocking effect on airflow; when the rack moves to the right along the tangent of gear 331, gear 331 rotates clockwise, decreasing the windward area of ​​housing 1 and weakening its blocking effect on airflow.

[0133] In some embodiments of this application, such as Figure 8 As shown, the soft wind assembly includes a mounting base 4 and multiple housings 1. Each housing 1 has an air diffuser 2 within its mounting space 100. The multiple housings 1 are arranged at intervals along the length of the mounting base 4.

[0134] With the above arrangement, since the air outlet of an air conditioner is generally elongated, the soft wind assembly can arrange multiple housings 1 on the air outlet of the air conditioner via the mounting base 4. This helps to improve the effect of the soft wind assembly in blocking and disrupting the airflow blown out by the air conditioner. At the same time, the mounting base 4 can also be used to connect the soft wind assembly to the air conditioner.

[0135] In this embodiment of the application, multiple housings 1 can be arranged at equal intervals along the length direction of the mounting base 4.

[0136] In some embodiments of this application, such as Figure 9 As shown, the soft wind assembly includes an air guide plate 5, and a housing 1 is mounted on one side of the air guide plate 5.

[0137] With the above arrangement, the air guide plate 5 can be directly installed on the air conditioner as part of the air conditioner during the assembly process, without the need to add other components to the air conditioner. This can reduce the complexity of the soft wind component assembly process.

[0138] A second aspect of this application provides an air conditioner that includes a gentle breeze assembly as described in the above embodiments.

[0139] Because of the use of the soft wind component in the above embodiments, the air conditioner of this application has the same technical effects as the above embodiments, which will not be repeated here.

[0140] In some embodiments of this application, the air conditioner includes a main body, and a plurality of soft wind components are installed at the air outlet of the main body.

[0141] With the above arrangement, multiple gentle breeze components can create a gentle breeze effect at different positions of the air outlet of the main body, reducing the situation where airflow directly blows onto the human body through the air outlet.

[0142] In some embodiments of this application, multiple soft wind components are arranged to form two groups, and the two groups of soft wind components are arranged at intervals along the length direction of the air outlet of the body, wherein the two groups of soft wind components are used to guide the airflow to the same side of the body.

[0143] With the above arrangement, the soft wind assembly can guide the airflow blown out by the air conditioner to the same side of the main body, thereby improving the independence between airflows passing through different soft wind assemblies and reducing the mutual interference between airflows due to the intersection of flow paths.

[0144] In the embodiments of this application, such as Figure 6 and Figure 7 As shown in the diagram, there are 14 gentle airflow components, with 7 on the left and 7 on the right forming a group. If both groups of gentle airflow components direct the airflow to the left side of the diagram, the airflow effect of the air conditioner on the corresponding left side of the space will be improved; if both groups of gentle airflow components direct the airflow to the right side of the diagram, the airflow effect of the air conditioner on the corresponding right side of the space will be improved.

[0145] In some embodiments of this application, multiple soft wind components are arranged to form two groups, and the two groups of soft wind components are arranged at intervals along the length direction of the air outlet of the body, wherein the two groups of soft wind components are used to guide the airflow to the opposite side of the body.

[0146] With the above arrangement, the air conditioner can guide the airflow from different positions of the air outlet outward along the original flow path, thereby expanding the blowing range of the air conditioner. Alternatively, the air conditioner can guide the airflow from different soft wind components to the same position, so that the paths of the airflows intersect and interfere with each other. The airflow speed of the interfering airflows is reduced, which helps to reduce the discomfort of the user when being blown by the air.

[0147] In the embodiments of this application, such as Figure 6 and Figure 7 As shown in the diagram, there are 14 gentle breeze components, with 7 on the left and 7 on the right forming a group. If the group of gentle breeze components on the left directs the airflow to the left side of the diagram, and the group of gentle breeze components on the right directs the airflow to the right side, the air conditioning's blowing range will be expanded. If the group of gentle breeze components on the left directs the airflow to the right side of the diagram, and the group of gentle breeze components on the right directs the airflow to the left side, the airflows directed by the two groups of gentle breeze components will collide, thus reducing the airflow velocity.

[0148] In this embodiment of the application, the gentle breeze assembly can adjust the direction of airflow guidance by adjusting the rotation of the blades 21.

[0149] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.
