DETAILED DESCRIPTION

[0033] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] Please refer to Figures 1 to 9 The present invention provides a spoiler device, which is used to be arranged at an air outlet 1 of an air outlet device. An air guide plate 2 for opening or closing the air outlet 1 is provided at the air outlet 1. The spoiler device includes a spoiler component 3, which is movably arranged at the air outlet 1 and is independently arranged with the air guide plate 2, so that the spoiler component 3 and the air guide plate 2 move independently of each other, so that when the air guide plate 2 opens the air outlet 1, the spoiler component 3 is movably arranged relative to the air outlet 1, so as to disturb the airflow at the air outlet 1 through the spoiler component 3.

[0035] The present invention provides a spoiler device, which includes a spoiler component. The spoiler component is provided to disturb the airflow at the air outlet, break up the airflow, and make the airflow blow out of the air outlet 1 in different directions. In the process of breaking up the airflow, the blowing intensity of the airflow is reduced, and the soft wind effect is improved. On the one hand, the air outlet range of the airflow is increased, and on the other hand, the airflow at the air outlet 1 has a certain vortex, which reduces the airflow velocity, so that the airflow reaches the golden velocity when reaching the human body surface, thereby improving user comfort, thereby solving the problem of poor comfort of the air guide component in the prior art.

[0036] Specifically, in order to achieve a better effect of breaking up the airflow, the spoiler component 3 in the embodiment of the present application includes a spoiler 31, which is rotatably arranged relative to the air outlet 1, so that when the air guide plate 2 opens the air outlet 1, the airflow at the air outlet 1 is disturbed by the rotation of the spoiler 31. Since the spoiler 31 has a certain width, part of the airflow will be blocked during the rotation of the spoiler 31, thereby reducing the flow rate of the airflow and improving the soft wind effect.

[0037] Furthermore, the rotation axis of the spoiler 31 in the embodiment of the present application extends along the length direction of the air outlet 1, so that the spoiler 31 breaks up the airflow during the rotation process.

[0038] Generally, since the air guide plate 2 is used to open or close the air outlet 1, the width of the spoiler 31 is set to be smaller than the width of the air guide plate 2, so that the air outlet 1 has sufficient avoidance space to allow the spoiler 31 to rotate around the rotation axis, preventing the spoiler 31 from contacting the air guide plate 2 during rotation, thereby avoiding damage to the spoiler 31.

[0039] In addition, if Figures 5 to 8 As shown, in order to install the spoiler component 3 at the air outlet 1 of the air outlet device, the spoiler component 3 also includes a connecting shaft 32, and the middle part of the spoiler 31 has a protrusion 33, and the protrusion 33 is provided with a through hole for the connecting shaft 32 to pass through. The connecting shaft 32 is fixed relative to the spoiler 31, so that the spoiler 31 is rotatably arranged relative to the air outlet 1 through the connecting shaft 32, so that the spoiler 31 rotates around the axis where the connecting shaft 32 is located.

[0040] In the first embodiment:

[0041] Specifically, there is one spoiler component and one drive motor. One spoiler component includes a spoiler 31 and two connecting shafts 32. The spoiler 31 is provided with protrusions 33 at both ends along the length direction of the air outlet 1. Each connecting shaft 32 is fixedly connected to each protrusion 33. The drive motor is arranged on the side wall of the air outlet device close to the air outlet 1. The output shaft of the drive motor is connected to one of the connecting shafts 32, so that the spoiler 31 is driven to rotate around the rotation axis by the drive motor driving the connecting shaft 32.

[0042] Preferably, the driving motor is a micro high-speed motor.

[0043] The spoiler device in this embodiment has a simple structure and only requires one drive motor, which reduces production costs and facilitates maintenance.

[0044] In the second embodiment:

[0045] Specifically, in order to enhance the spoiler effect of the spoiler device so that the spoiler device can be in different spoiler states at the same time, thereby enhancing the user's comfort, there are multiple spoiler components 3, and the multiple spoiler components 3 are sequentially arranged along the length direction of the air outlet 1; wherein, two adjacent spoiler components 3 are spaced apart to form a ventilation gap 5. Such an arrangement reduces the spoiler area, thereby reducing the loss of air volume, thereby enhancing the air volume of the air outlet device and enhancing the cooling effect.

[0046] Among them, at least two spoiler components 3 among the multiple spoiler components 3 are relatively movably arranged to respectively control the movement of the corresponding spoiler components 3, so that the spoiler components 3 can be in different spoiler states, increasing the diversity of air supply and improving the spoiler effect.

[0047] The spoiler device in this embodiment is provided with multiple spoiler components 3, and the multiple spoiler components 3 can be in at least two different spoiler states at the same time, or perform spoiler at different wind speeds and / or angles, thereby increasing the diversity of air supply and improving the spoiler effect, thereby improving user comfort.

[0048] In a third embodiment:

[0049] Specifically, in order to enhance the spoiler effect of the spoiler device so that the spoiler device can be in different spoiler states at the same time, thereby enhancing the user's comfort, there are multiple spoiler components 3, and the multiple spoiler components 3 are sequentially arranged along the length direction of the air outlet 1; wherein, two adjacent spoiler components 3 are spaced apart to form a ventilation gap 5. Such an arrangement reduces the spoiler area, thereby reducing the loss of air volume, thereby enhancing the air volume of the air outlet device and enhancing the cooling effect.

[0050] Among them, multiple spoiler components 3 are divided into multiple groups of spoiler components, each spoiler component includes at least two spoiler components 3 connected to each other, so that at least two spoiler components 3 in each group of spoiler components move synchronously; wherein, each spoiler component moves relatively independently, so that the spoiler component can be in different spoiler states, increasing the diversity of air supply and improving the spoiler effect.

[0051] Furthermore, each spoiler component 3 includes a spoiler plate 31 and a connecting shaft 32 that are connected to each other, and two adjacent spoiler components 3 in each group of spoiler components are connected to each other through their respective connecting shafts 32 .

[0052] In addition, in order to enable each spoiler assembly to move relatively independently, the spoiler device also includes a rotating component 34. The two adjacent spoiler assemblies are respectively a first spoiler assembly and a second spoiler assembly. The connecting shaft 32 of the spoiler assembly 3 in the first spoiler assembly close to the second spoiler assembly is relatively rotatably connected to the connecting shaft 32 of the spoiler assembly 3 in the second spoiler assembly close to the first spoiler assembly through the rotating component 34, so that the various spoiler assemblies can rotate around the same rotation axis while performing spoiling at different wind speeds and / or angles.

[0053] The spoiler device in this embodiment divides the multiple spoiler components 3 into multiple groups of spoiler components, so that the spoiler device can perform spoiling at different wind speeds and / or angles at the same time, while reducing the number of drive motors. Such a setting not only takes into account the practicality of the spoiler device, but also reduces the production cost.

[0054] In the fourth embodiment:

[0055] like Figure 5 and Figure 6 As shown, in order to facilitate the setting of the driving motor and the spoiler component 3, there are two spoiler components 3, each spoiler component 3 includes a spoiler plate 31 and a connecting shaft 32 connected to each other, and the spoiler device also includes a rotating component 34, and the connecting shaft 32 of one spoiler component 3 is relatively rotatably connected to the connecting shaft 32 of another spoiler component 3 through the rotating component 34.

[0056] Specifically, there are two spoilers 31 and four connecting shafts 32. Each spoiler 31 is provided with a protrusion 33 at both ends along the length direction of the air outlet 1. Each connecting shaft 32 is fixedly connected to each protrusion 33. The two connecting shafts 32 between the two spoilers 31 are connected by a rotating part 34 to form a ventilation gap 5 for air flow to pass through between the two spoilers 31.

[0057] Furthermore, there are two drive motors, which are respectively arranged on the two side walls of the air outlet device close to the air outlet 1; the two connecting shafts 32 away from the rotating part 34 are respectively connected to the output shafts of the two drive motors, so that each drive motor drives each spoiler 31 to rotate around the axis where the connecting shaft 32 is located.

[0058] Preferably, the driving motor is a micro high-speed motor.

[0059] The spoiler device in this embodiment is provided with two spoiler components 3, and the two spoiler components 3 move independently, so that the spoiler device can spoil the wind at different wind speeds and / or angles at the same time, while having a simple structure, reducing production costs and facilitating maintenance.

[0060] In the fifth embodiment:

[0061] like Figure 7 and Figure 8 As shown, in order to reduce the turbulence area and reduce the loss of wind volume, there are four spoiler components 3, each of which includes a spoiler plate 31 and a connecting shaft 32 connected to each other, and the spoiler device also includes a rotating component 34.

[0062] Specifically, the spoiler 31 includes a first spoiler 311, a second spoiler 312, a third spoiler 313 and a fourth spoiler 314; the connecting shaft 32 includes two first connecting shafts 321, two second connecting shafts 322, two third connecting shafts 323 and two fourth connecting shafts 324; the two first connecting shafts 321 are respectively connected to the two ends of the first spoiler 311, the two second connecting shafts 322 are respectively connected to the two ends of the second spoiler 312, the two third connecting shafts 323 are respectively connected to the two ends of the third spoiler 313, and the two fourth connecting shafts 324 are respectively connected to the two ends of the fourth spoiler 314.

[0063] Furthermore, the drive motor includes a first drive motor and a second drive motor, and the first drive motor and the second drive motor are respectively arranged on two side walls of the air outlet device close to the air outlet 1.

[0064] Among them, a first connecting shaft 321 is drivingly connected to the output shaft of the first drive motor, and another first connecting shaft 321 is fixedly connected to a second connecting shaft 322 to drive the first spoiler 311 and the second spoiler 312 to rotate through the first drive motor; a fourth connecting shaft 324 is drivingly connected to the output shaft of the second drive motor, and another fourth connecting shaft 324 is fixedly connected to a third connecting shaft 323 to drive the third spoiler 313 and the fourth spoiler 314 to rotate through the second drive motor.

[0065] Furthermore, the second connecting shaft 322 and the third connecting shaft 323 between the second spoiler 312 and the third spoiler 313 are connected by a rotating component 34, so that the first spoiler 311 and the second spoiler 312 can move independently relative to the third spoiler 313 and the fourth spoiler 314.

[0066] Specifically, ventilation gaps 5 for airflow to pass through are formed between the first spoiler 311 , the second spoiler 312 , the third spoiler 313 and the fourth spoiler 314 .

[0067] Preferably, the first drive motor and the second drive motor are both micro high-speed motors.

[0068] The spoiler device in this embodiment is provided with four spoiler components 3, and the four spoiler components 3 are divided into two groups of spoiler components. The two groups of spoiler components move independently, so that the spoiler device can perform spoiling at different wind speeds and / or angles at the same time, while increasing the ventilation gap 5, reducing the spoiler area, reducing the air volume loss, and improving the cooling efficiency.

[0069] Generally, in the above embodiments, the spoiler device includes a rotating component 34, each spoiler component 3 includes a spoiler plate 31 and a connecting shaft 32 connected to each other, and the connecting shafts 32 of two adjacent spoiler components 3 among the multiple spoiler components 3 are rotatably connected by the rotating component 34. The rotating component 34 is a bearing component, the inner ring of the bearing component is connected to a corresponding one of the connecting shafts 32, and the outer ring of the rotating component 34 is connected to a corresponding other connecting shaft 32.

[0070] In addition, the specific configuration of the connecting shaft 32 is as follows:

[0071] One setting method is: a spoiler component 3 includes a spoiler 31 and a connecting shaft 32, a mounting hole is provided on the spoiler 31, and the connecting shaft 32 is relatively fixedly inserted into the mounting hole, and the two ends of the connecting shaft 32 are respectively connected to the two ends of the spoiler 31 along the length direction of the air outlet 1. This setting makes the connection between the connecting shaft 32 and the spoiler 31 more stable.

[0072] Another setting method is: a spoiler component 3 includes a spoiler 31 and two connecting shafts 32, and the spoiler 31 is respectively provided with protrusions 33 at both ends along the length direction of the air outlet 1, and the two connecting shafts 32 are respectively fixedly connected to the two protrusions 33. Such a setting can shorten the length of the connecting shaft 32, save the material of the connecting shaft 32, thereby reducing energy waste and reducing production costs.

[0073] Furthermore, in order to drive the spoiler component 3 to rotate around the rotation axis, in the above embodiment, the spoiler device also includes a drive motor, which is installed on the air outlet device, and the output shaft of the drive motor is driven and connected to the spoiler component 3 to drive the spoiler component 3 to rotate through the drive motor.

[0074] Preferably, the driving motor is a micro high-speed motor, so that the spoiler 3 can rotate around the rotation axis at any angle and at any speed.

[0075] Specifically, in order to achieve different spoiler effects and achieve different spoiler purposes, the spoiler component 3 has a swinging spoiler state and a rotating spoiler state. When the spoiler component 3 is in the swinging spoiler state, the spoiler component 3 swings around a predetermined rotation axis and within a predetermined swing angle; when the spoiler component 3 is in the rotating spoiler state, the spoiler component 3 rotates around the predetermined rotation axis at an angle of 360°.

[0076] like Figure 3 As shown, when the spoiler 3 is in the swinging spoiler state, the spoiler 31 first rotates to a first predetermined position between the spoiler 31 and the air guide 2, forming a flow path for air to flow through the air supply channel 4. The spoiler 3 then swings around the predetermined rotation axis at a first predetermined speed, using the first predetermined position as a reference, between a second predetermined position and a third predetermined position. At this point, the spoiler 3 disturbs the airflow at the air outlet 1 at the first predetermined speed, creating a "fishtail" swinging flow at the air outlet 1, improving comfort without sacrificing airflow.

[0077] The air supply channel 4 extends along the air outlet direction of the air outlet 1; and the angle between the second predetermined position and the third predetermined position is the predetermined swing angle.

[0078] Specifically, the predetermined rotation axis extends along the length direction of the air outlet 1 .

[0079] In addition, the predetermined swing angle ranges from 0° to 180°.

[0080] like Figure 4 As shown, when the spoiler 3 is in the rotating spoiler state, the spoiler 31 rotates 360 degrees around the predetermined rotation axis at a second predetermined speed. At this time, the spoiler 3 disturbs the airflow at the air outlet 1 at the second predetermined speed, breaking up the airflow and enhancing the soft wind effect. This not only increases the airflow range, but also creates a certain amount of vortex in the airflow at the air outlet 1, reducing the airflow velocity. When the airflow reaches the human body surface, it reaches the golden flow velocity, improving user comfort.

[0081] Generally, the spoiler 3 has an initial state and an air supply state.

[0082] Specifically, if Figure 1 As shown, when the air guide plate 2 is located at the position closing the air outlet 1, the spoiler component 3 is in the initial state relative to the air guide plate 2. At this time, the air outlet 1 of the air outlet device is closed and there is no airflow through the air outlet 1.

[0083] like Figure 2 As shown, when the air guide plate 2 is in the position that opens the air outlet 1 and the spoiler 3 is in the air supply state, a supply airflow is formed between the spoiler 3 and the air guide plate 2, passing through the air supply channel 4. The air supply channel 4 extends along the outlet direction of the air outlet 1. At this time, the air guide plate 2 and the spoiler 31 divide the airflow from the air outlet 1 into three layers: upper, middle, and lower. All three layers of airflow blow directly towards the user. At this time, the air volume is maximized, and cooling can be achieved quickly, but the comfort is poor.

[0084] The present invention also provides an air-conditioning indoor unit, which includes an air-conditioning shell having an air outlet 1 and an air guide plate 2, which is openably installed at the air outlet 1. The air-conditioning indoor unit also includes the above-mentioned spoiler device, which is arranged on the inner side of the air guide plate 2.

[0085] The air conditioner indoor unit further comprises a detection component and a control module, wherein the detection component and the drive motor are both connected to the control module. The detection component is used to detect the indoor wind sensation index and the power spectrum density index.

[0086] Wherein, the air outlet device in the above embodiment is an air conditioner indoor unit.

[0087] In addition, if Figure 9 As shown, an embodiment of the present application further provides a method for controlling an air conditioner indoor unit, the control method comprising:

[0088] S01: Turn on the air conditioner indoor unit, the air guide plate 2 opens the air outlet 1, and the spoiler 3 switches from the initial state to the air supply state;

[0089] S03: If the spoiler component 3 is controlled to switch to the rotating spoiler state, the driving motor drives the spoiler component 3 to rotate clockwise or counterclockwise around the predetermined rotation axis at a second predetermined speed;

[0090] S05: After the first predetermined time period, if it is detected that the indoor wind sensation index is less than 10 and the power spectrum density index is greater than or equal to 1.1 and less than or equal to 2, the spoiler 3 maintains the rotating spoiler state until the air conditioner indoor unit is turned off;

[0091] S07: After the first predetermined time period, if it is detected that the indoor wind sensation index is greater than or equal to 10, or the power spectrum density index is less than 1.1 or greater than 2, the second predetermined speed is changed until it is detected that the indoor wind sensation index is less than 10 and the power spectrum density index is greater than or equal to 1.1 and less than or equal to 2. At this time, the spoiler 3 maintains the rotating spoiler state until the air conditioner indoor unit is turned off;

[0092] S09: If the spoiler 3 is switched to the swing spoiler state, the driving motor drives the spoiler 3 to swing around the predetermined rotation axis within a predetermined swing angle at a first predetermined speed;

[0093] S11: After the second predetermined time period, if it is detected that the indoor wind sensation index is less than 10 and the power spectrum density index is greater than or equal to 1.1 and less than or equal to 2, the spoiler 3 maintains the swing spoiler state until the air conditioner indoor unit is turned off;

[0094] S13: After the second predetermined time period, if it is detected that the indoor blowing sensation index is greater than or equal to 10, or the power spectrum density index is less than 1.1 or greater than 2, the first predetermined speed is changed until it is detected that the indoor blowing sensation index is less than 10, and the power spectrum density index is greater than or equal to 1.1 and less than or equal to 2. At this time, the spoiler component 3 maintains the swinging spoiler state until the air conditioner indoor unit is turned off.

[0095] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0096] The present invention provides an air conditioner indoor unit. Since the air flow blown out of the air outlet 1 of the air conditioner indoor unit directly blows for a long time and affects the health of the user, the present invention provides a spoiler device. The air conditioner indoor unit includes a spoiler device, which is used to be arranged at the air outlet 1 of the air outlet device. The air outlet 1 is provided with an air guide plate 2 for opening or closing the air outlet 1. The spoiler device includes a spoiler component 3. The spoiler component 3 is movably arranged at the air outlet 1 and is independently arranged with the air guide plate 2, so that when the air guide plate 2 opens the air outlet 1, the spoiler component 3 is movably arranged relative to the air outlet 1. By arranging the spoiler component 3, the air flow at the air outlet 1 is disturbed and the air flow is dispersed, so that the air flow can be blown out of the air outlet 1 in different directions. In the process of dispersing the air flow, the blowing intensity of the air flow is reduced, thereby improving the soft wind effect. On the one hand, the air outlet range of the air flow is increased, and on the other hand, the air flow at the air outlet 1 has a certain vortex, which reduces the air flow velocity, so that the air flow reaches the golden flow velocity when it reaches the human body surface, thereby improving the user comfort, thereby solving the problem of poor comfort of the air guide component in the prior art.

[0097] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
