Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air outlet guide of household appliances, and particularly to an air outlet system and an intelligent air sensing and adjusting method thereof. BACKGROUND

[0002] In the current air outlet system of household appliances and the like, a fan, an air duct and an air guide assembly are generally included. The air guide assembly is installed at the outlet of the air duct, and the air generated by the fan is blown out after passing through the air guide assembly. The air duct adjusts the wind direction and size and the like of the air outlet through the air guide assembly. The existing air guide assembly generally achieves the effect of left-right or up-down air swing of the air outlet by swinging the air guide plate left and right or up and down. Although the air direction can be changed in this way, the air flow is forced to be diverted by the air guide plate, which will cause a certain reduction in air volume or air speed. Moreover, the blown-out air is hard and not soft enough, which reduces the user experience effect.

[0003] In addition, the inventor found in the implementation of the present application that the existing air guide system has too single air adjusting mode and low intelligence, and cannot intelligently adjust the air according to the real-time conditions such as the position, distance and activity state of the user relative to the air guide system, so as to provide the most comfortable space temperature for the user and affect the user experience effect. SUMMARY

[0004] In order to overcome at least one of the defects of the prior art described above, one of the purposes of the present application is to provide an air outlet system capable of realizing air deflection without reducing air speed and volume, and the air outlet is more gentle and comfortable.

[0005] The second purpose of the present application is to provide an intelligent air sensing and adjusting method of an air outlet system with high intelligence and capable of adjusting the air in real time according to different positions of the user.

[0006] The technical solution adopted by the present application to achieve the above-mentioned one of the purposes is as follows:

[0007] The present application provides an air outlet system, which comprises a fan, an air duct and a moving driving device. The air duct is provided with an air guide assembly. The air flow blown out by the fan is blown out after passing through the air guide assembly. The air guide assembly comprises at least two air guide plates arranged in a row and spaced apart. The cross section of the air guide plate is D-shaped. One side of the air guide plate is a flat air guide surface, and the other side of the air guide plate is an arc air guide surface. Adjacent two air guide plates are arc air guide surface to arc air guide surface or flat air guide surface to flat air guide surface. The area in front of the air outlet system is set as a priority area, and the area on the side of the priority area is set as a secondary priority area. When the user is located in the secondary priority area, the moving driving device drives the air guide plate to move forward and backward relative to the adjacent air guide plate in the direction of the air flow blown out by the fan, so that the air flow blown out by the fan is deflected after passing through the air guide assembly, and then the air is guided to the secondary priority area.

[0008] The air outlet system of the present application, by setting the air guide assembly composed of at least two D-shaped air guide plates, and the adjacent two air guide plates are arc air guide surfaces corresponding to arc air guide surfaces or plane air guide surfaces corresponding to plane air guide surfaces, when the user is located in the secondary priority area, the moving drive device drives the air guide plate to move forward and backward relative to its adjacent air guide plate in the direction of the air flow blown by the fan, so that the adjacent air guide plates can be staggered, so that the air flow blown from the fan can be self-excited after passing through the air guide assembly. Deflection, and then guide the wind to the secondary priority area, due to the combination of arc air guide surface and plane air guide surface, and the air passing through the arc air guide surface can achieve the effect of reaching the kang, this self-excited deflection of the air can not only avoid the reduction of air volume or air speed, but also the blown air is more soft and comfortable, and the user experience effect is improved.

[0009] Preferably, the rotating drive device is included, and when the user is located in the secondary priority area, the rotating drive device can drive the air guide plate to rotate around its rotating shaft to make the air flow blown by the fan deflect after passing through the air guide assembly. The rotation of the air guide plate can significantly enhance the deflection of the air flow, so that more air is blown to the secondary priority area, meeting the diversified needs of users.

[0010] Preferably, the moving distance of the air guide plate is P, the chord length of the air guide plate is Φ, and 0

[0011] Preferably, the rotating angle of the air guide plate is θ, and 0°< θ < 15°. The limitation of the rotating angle of the air guide plate ensures that the deflection of the air guide assembly can be enhanced.

[0012] The technical scheme adopted by the present application to achieve the above-mentioned purpose is:

[0013] The intelligent sensing and air adjusting method of the air outlet system uses the above-mentioned air outlet system, which comprises:

[0014] The air outlet system is provided with a controller and a position sensing device, and the position sensing device and the moving drive device are electrically connected with the controller;

[0015] If the position sensing device senses that the user is located in the priority area, the controller drives the air guide plate to return to the initial position through the moving drive device, so that the air flow blown by the fan does not deflect after passing through the air guide assembly and blows to the priority area; if the position sensing device senses that the user is located in the secondary priority area, the controller drives the air guide plate to move forward and backward relative to its adjacent air guide plate in the direction of the air flow blown by the fan through the moving drive device, so that the air flow blown by the fan deflects after passing through the air guide assembly, and then guides the wind to the secondary priority area.

[0016] The intelligent sensing air adjusting method of the air outlet system of the application, by using the air outlet system, senses whether the user is located in the priority area or the sub-priority area according to the orientation sensing device, if the user is in the priority area, the controller drives the air deflector back to the initial position through the movement driving device, so that the airflow blown by the fan does not deviate after passing through the air deflector assembly, but is directly blown to the priority area, if the user is in the sub-priority area, the controller drives the air deflector to move forward and / or backward relative to the adjacent air deflector in the direction of the airflow blown by the fan through the movement driving device, so that the airflow blown by the fan deviates after passing through the air deflector assembly, and then guides the air to the sub-priority area. The application realizes real-time intelligent air adjustment according to the current position of the user, and brings more comfortable and intelligent air blowing experience to the user.

[0017] Preferably, if the orientation sensing device senses that part of the users are located in the priority area and part of the users are located in the sub-priority area, the controller drives the air deflector close to the sub-priority area to move forward and / or backward relative to the adjacent air deflector in the direction of the airflow blown by the fan through the movement driving device, so as to guide part of the airflow blown by the fan to the sub-priority area, and the controller drives the air deflector close to the priority area back to the initial position through the movement driving device, so that part of the airflow blown by the fan does not deviate but is directly blown to the priority area. This can meet the needs of special use scenarios of users and meet the needs of market multifunctional and diversified intelligence.

[0018] Preferably, the air outlet system is provided with a crowd identification device capable of automatically identifying user groups, the crowd identification device and the fan are electrically connected with the controller; according to the crowd mode to which the user belongs identified by the crowd identification device, the controller adjusts the air outlet speed and air outlet temperature of the fan. This increases the adjustment parameters of the air outlet system, according to the different physiological metabolisms of different crowd modes, for example, the physiological metabolisms of the elderly and children are very different, the application automatically adjusts the corresponding air outlet speed and air outlet temperature of the fan, so as to achieve the best comfortable temperature felt by different users.

[0019] Preferably, the crowd mode includes an elderly mode, a child mode and an adult mode, and the adult mode includes a female adult mode and a male adult mode. Because the metabolisms of different crowd modes are different, the corresponding air outlet speed and air outlet temperature should be adjusted appropriately, and as far as possible, adjusted to the best comfortable temperature felt by different crowd modes.

[0020] Preferably, the air supply system is equipped with a status recognition device that can automatically identify the user's status. Both the status recognition device and the fan are electrically connected to the controller. Based on the user's current status identified by the status recognition device, the controller adjusts the fan's airflow speed and airflow temperature. Users may be in a leisure state, a working state, or a state of strenuous activity. Even for the same user, the level of activity and metabolic rate will differ depending on the state. Therefore, to achieve the optimal comfortable temperature for the user, it is necessary to automatically adjust the fan's airflow speed and airflow temperature.

[0021] Preferably, the air outlet system is equipped with an environmental sensor capable of sensing the ambient air temperature and humidity. Both the environmental sensor and the fan are electrically connected to the controller. Based on the ambient air temperature and humidity sensed by the environmental sensor, the controller adjusts the fan's outlet speed and outlet air temperature. The environmental sensor further enhances the intelligent sensing and adjustment parameters of the airflow. The more adjustment parameters there are, the more accurately the system reflects the user's actual situation, making the airflow from the adjusted system closer to the user's optimal comfort level. This provides the user with a more intelligent, technological, and comfortable experience. Attached Figure Description

[0045] In order to better understand and implement, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application.

[0046] In the description of the present application, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the present application.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0048] The air outlet system of the embodiment comprises a fan and an air duct 7 (as shown in Figure 12 and Figure 13 The air duct 7 is provided with a wind guide assembly. The air flow blown by the fan is blown out after passing through the wind guide assembly. The wind guide assembly comprises at least two wind guide plates arranged in a row and spaced apart. The embodiment preferably uses four wind guide plates for illustration, as shown in Figure 1 The four wind guide plates are respectively a first wind guide plate 1, a second wind guide plate 2, a third wind guide plate 3 and a fourth wind guide plate 4. The cross section of all the wind guide plates is D-shaped. One side of all the wind guide plates is a planar wind guide surface 5, and the other side is an arc-shaped wind guide surface 6. The first wind guide plate 1, the second wind guide plate 2, the third wind guide plate 3 and the fourth wind guide plate 4 are arranged in a row in the transverse direction. The planar wind guide surface 5 corresponding to the planar wind guide surface 5 is arranged between the first wind guide plate 1 and the second wind guide plate 2. The arc-shaped wind guide surface 6 corresponding to the arc-shaped wind guide surface 6 is arranged between the second wind guide plate 2 and the third wind guide plate 3. The planar wind guide surface 5 corresponding to the planar wind guide surface 5 is arranged between the third wind guide plate 3 and the fourth wind guide plate 4. Figures 1 to 6 The arrow in the figure indicates the direction of the air flow blown by the fan after passing through the wind guide assembly.

[0049] As shown in Figures 1-6 The front area of the air outlet system, that is, the front area of the wind guide assembly, is set as a priority area 8. The areas on the left and right sides of the priority area 8 are set as secondary priority areas 9. When the air outlet of the air outlet system needs to be blown to the priority area 8, the wind guide assembly is in the initial position as shown in Figure 1 , and there is no need to deflect the wind. When the air outlet of the air outlet system needs to be blown to the secondary priority area 9, the wind guide assembly needs to deflect the wind so that the wind can be blown to the secondary priority area 9.

[0050] As shown in Figure 1 All the wind guide plates are in the original initial position and do not change. The air flow blown from the fan passes through the first wind guide plate 1, the second wind guide plate 2, the third wind guide plate 3 and the fourth wind guide plate 4, and the air flow is still blown forward to the user in the priority area 8. As shown in the flow field simulation diagram Figure 7 , it can be further verified that the air flow is blown forward. In addition, as shown in the velocity simulation data diagram from the center of the flow field Figure 11 It can be seen that the air flow passing through the wind guide assembly is obviously higher in speed than the air flow passing through the existing air deflection structure, such as a grille structure, at a position very close to the air outlet of the air outlet system.

[0051] As shown in Figure 2As shown, when the user is located in the secondary priority zone 9 on the right, the moving drive device drives the second guide plate 2 relative to the first guide plate 1 and the fourth guide plate 4 relative to the third guide plate 3 to move forward in the direction of the airflow blown out by the fan. This causes the second guide plate 2 and the fourth guide plate 4 to be horizontally offset from the corresponding first guide plate 1 and third guide plate 3, thus allowing the airflow blown out by the fan to undergo self-excited rightward deflection after passing through the first guide plate 1, the second guide plate 2, the third guide plate 3, and the fourth guide plate 4. This is illustrated in the flow field simulation diagram. Figure 8 As shown, the airflow blown by this air guide component is clearly deflected to the right and forward. This self-excited deflection not only changes the wind direction, but also, due to the organic combination of the curved air guide surface 6 and the flat air guide surface 5, effectively avoids a reduction in airflow or speed. Furthermore, the Dacon effect formed by the wind on the curved air guide surface 6 makes the blown air feel softer and more comfortable, improving the user experience. Additionally, the velocity simulation data from the center of the flow field is shown in the figure below. Figure 11 As shown, it is evident that the airflow velocity through this air guide component, very close to the air outlet of the air outlet system, is significantly higher than that of existing air conditioning structures, such as grille structures. Furthermore, as... Figure 8 The airflow from the arranged air guide components is self-excited and deflected to the right. Therefore, even if the outflow is already deflected, such as... Figure 11 As shown, the flow velocity at the center of the flow field is comparable to that of a conventional direct-flow air conditioning structure downstream (e.g., at 2.5m). This indicates that the self-generated flow field of the present invention can be directed to a distance as far as a conventional direct-flow air conditioning structure, which proves that the present invention does not reduce the airflow volume or speed after deflecting the airflow.

[0052] and Figure 2 Similar to the central air guide component, such as Figure 3 As shown, when the user is located in the secondary priority zone 9 on the left, the moving drive device drives the first air guide plate 1 relative to the second air guide plate 2, and the third air guide plate 3 relative to the fourth air guide plate 4, to move forward in the direction of the airflow blown out by the fan. This causes the first air guide plate 1 and the third air guide plate 3 to be horizontally offset from the corresponding second air guide plate 2 and fourth air guide plate 4. This allows the airflow blown out by the fan to undergo a self-excited deflection to the left after passing through the first air guide plate 1, the second air guide plate 2, the third air guide plate 3, and the fourth air guide plate 4, thus directing the airflow towards the user in the secondary priority zone 9. This self-excited deflection not only changes the airflow direction but also, due to the organic combination of the curved air guide surface 6 and the flat air guide surface 5, avoids a reduction in airflow volume or speed, resulting in a softer and more comfortable airflow and improving the user experience. Figure 3 The flow field simulation diagram and velocity simulation data diagram caused by the air guide component are compared with Figure 2The flow field simulation diagram and velocity simulation data diagram of the air guide component are similar, except that the bias is in the opposite direction, which will not be elaborated here.

[0053] like Figure 4 As shown, when some users are located in priority zone 8 and some users are located in the secondary priority zone 9 on the right, the moving drive device drives the fourth air guide plate 4 to move forward relative to the third air guide plate 3 in the direction of the airflow blown by the fan. The first air guide plate 1 and the second air guide plate 2 remain in their initial positions, so that the fourth air guide plate 4 can be offset from the corresponding third air guide plate 3 laterally. This allows the airflow blown by the fan to be divided into two parts after passing through the first air guide plate 1, the second air guide plate 2, the third air guide plate 3, and the fourth air guide plate 4. The left part of the airflow blows directly forward to priority zone 8 after passing through the first air guide plate 1 and the second air guide plate 2, while the right part of the airflow undergoes self-excited rightward deflection after passing through the third air guide plate 3 and the fourth air guide plate 4. This allows the air outlet system to achieve deflection of airflow in special directions and for special needs through the air guide components, thereby meeting the usage needs of customers in different scenarios.

[0054] and Figure 4 Similar to the air guide components in, such as Figure 5 As shown, when some users are located in the central priority zone 8 and some users are located in the left secondary priority zone 9, the moving drive device drives the first air guide plate 1 to move forward relative to the second air guide plate 2 in the direction of the airflow from the fan. The third air guide plate 3 and the fourth air guide plate 4 remain in their initial positions, so that the first air guide plate 1 can be offset from the corresponding second air guide plate 2 laterally. This allows the airflow from the fan to be divided into two parts after passing through the first air guide plate 1, the second air guide plate 2, the third air guide plate 3, and the fourth air guide plate 4. The left part of the airflow undergoes self-excitation and deflects to the left after passing through the first air guide plate 1 and the second air guide plate 2, blowing towards the users in the left secondary priority zone 9. The right part of the airflow passes through the third air guide plate 3 and the fourth air guide plate 4 and blows directly forward towards the users in the priority zone 8. The flow field simulation diagram is shown below. Figure 9 As shown, the airflow from this air guide component is partly direct and partly deflected to the left. This allows the air outlet system to achieve deflected airflow in specific directions and to meet the needs of customers in different scenarios.

[0055] like Figure 6As shown, when the user is located in the priority area 8 and is far away from the air outlet system, the air flow needs to be more concentrated and blow farther. Moving the driving device drives the second air deflector 2 relative to the first air deflector 1 and drives the third air deflector 3 relative to the fourth air deflector 4 to translate forward in the direction of the air flow blown by the fan, so that the second air deflector 2 and the third air deflector 3 can be staggered front and back with the corresponding first air deflector 1 and fourth air deflector 4 in the transverse direction, thereby causing the air flow blown by the fan to be divided into two parts, one part of the air flow is self-excitedly deflected to the right through the first air deflector 1 and the second air deflector 2, and the other part of the air flow is self-excitedly deflected to the left through the third air deflector 3 and the fourth air deflector 4, and the two parts of the air flow are collected through the deflection to the rear middle part, so that the air flow is more concentrated in the priority area 8 and blows farther. As shown in the flow field simulation diagram Figure 10 As shown, it can also be seen that the air flow blown through the air deflection assembly is more concentrated and blows farther. This enables the air outlet system to realize different air control modes through the air deflection assembly, thereby meeting the use requirements of customers in different scenes.

[0056] The air outlet system of the present application can realize deflection of different air directions by adjusting the relative positions between adjacent air deflectors in the air deflection assembly, not only enabling the air flow blown by the fan to be self-excitedly deflected through the air deflection assembly, but also avoiding reduction of air volume or air speed, and making the blown air feel softer and more comfortable, thereby effectively improving the user experience effect. In addition, the present application can also realize adjustment of different air directions to meet the use requirements of customers in various scenes.

[0057] As shown in Figure 12 To achieve the best deflection effect, the moving distance of each air deflector relative to its adjacent air deflector is set as P, for example, the moving distance of the second air deflector 2 relative to the first air deflector 1 is P, the chord length of the arc surface of the air deflector is Φ, for example, the chord length of the arc surface of the first air deflector 1 is Φ, that is, the maximum width of the first air deflector is Φ. To achieve the deflection effect, 0

[0058] Further, as shown in Figure 12As shown, in order to meet the use requirements of different scenes, for example, it is required that the air flow blown out by the air guiding assembly is more concentrated or more uniform, the size parameters of the air guiding plates, the relative position parameters between the air guiding plates and the position parameters between the air guiding plates and the inner side wall of the air duct 7 need to be reasonably set. In this embodiment, the maximum thickness of all air guiding plates is s, the distance between the planar air guiding surface 5 of the first air guiding plate 1 and the planar air guiding surface 5 of the second air guiding plate 2 is a, the distance between the planar air guiding surface 5 of the third air guiding plate 3 and the planar air guiding surface 5 of the fourth air guiding plate 4 is also a, the distance between the vertex of the arc air guiding surface 6 of the second air guiding plate 2 and the vertex of the arc air guiding surface 6 of the third air guiding plate 4 is h, and the distance between the vertex of the arc air guiding surface 6 of the first air guiding plate 1 and the vertex of the arc air guiding surface 6 of the fourth air guiding plate and the inner side wall of the air duct 7 is b. The parameters h, a and b can be adjusted according to the scene relative to s, for example, when the air flow blown out needs to be more concentrated, the value of the parameter h needs to be greater than the value of s, in addition, a and b can be equal to s, for example, s = 0.01 m, h = 0.02 m, a = b = 0.01 m; when the air flow blown out needs to be more uniform, the value of the parameter h is set to be equal to s, in addition, a and b are also equal to s, for example, s = 0.01 m, h = a = b = 0.01 m.

[0059] In order to make the air flow of the air outlet system more obvious after passing through the air guiding assembly, the rotation angle of the air guiding plate can be adjusted, for example, Figure 13 As shown, after the moving driving device drives the second air guiding plate 2 to move forward, the rotating driving device drives the planar air guiding surface of the second air guiding plate 2 to tilt outwardly by a certain angle, which is set to θ, in order to enhance the deflection air guiding, 0° < θ < 15°, preferably, when θ = 10°, the right deflection air guiding effect of the air guiding assembly is best, and the wind speed also increases correspondingly, and the air flow can be blown farther.

[0060] In this embodiment, an air guiding assembly consisting of four horizontally spaced air guide plates is used as an example. Of course, the air guiding assembly of the present invention can also consist of two horizontally spaced air guide plates, or three horizontally spaced air guide plates. Furthermore, the air guiding assembly of the present invention can also consist of two, three, or four vertically spaced air guide plates. The horizontally arranged air guide plates can deflect air left and right, thereby directing the air to the secondary priority zones 9 located on the left and right sides of the priority zone 8. The vertically arranged air guide plates can deflect air up and down, thereby directing the air to the secondary priority zones 9 located on the front and rear sides of the priority zone 8 (not specifically shown in the figures in this embodiment). In this embodiment, the air guide plates are moved forward in the direction of the airflow blown by the fan, thereby forming various deflection airflow adjustment modes. Of course, depending on the specific installation position of the air guiding assembly within the duct 7, various deflection airflow adjustment modes can also be formed by controlling the air guide plates to move backward in the direction of the airflow blown by the fan, or by partially moving the air guide plates forward and partially moving them backward. In this embodiment, the deflection effect is enhanced by first translating the air guide into position and then rotating it. Of course, the air guide can also be rotated first and then translated, etc., to achieve the same effect of enhancing the deflection effect.

[0061] In this embodiment, both the moving drive device and the rotating drive device are existing drive mechanisms. For example, the moving drive device can be a drive cylinder, and the rotating drive device can be a motor, etc., which will not be described in detail here.

[0062] An intelligent sensing and air adjustment method for an air outlet system, which can be applied to air conditioning products, utilizes the aforementioned air outlet system, including:

[0063] The air outlet system is equipped with a controller and a position sensor, both of which are electrically connected to the controller.

[0064] like Figure 1 As shown, if the orientation sensing device detects that the user is located in priority zone 8, the controller drives the air guide plate back to its initial position via the movement drive device, so that the airflow blown by the fan does not deflect after passing through the air guide assembly, but blows directly towards priority zone 8; as Figures 2-3 As shown, if the orientation sensing device detects that the user is located in the secondary priority zone 9, the controller drives the air guide plate to move back and forth relative to its adjacent air guide plate in the direction of the airflow blown by the fan via the motion drive device. This causes the airflow blown by the fan to be deflected after passing through the air guide assembly, thereby guiding the airflow to the secondary priority zone 9. This invention enables real-time intelligent adjustment of the airflow direction based on the user's current location, providing the user with a more comfortable and intelligent airflow experience.

[0065] The orientation sensing device can be a radar sensor or an infrared temperature sensor. Through the orientation sensing device, the user's current location in the priority zone 8 or the sub-priority zone 9 can be sensed in real time, and the information is transmitted to the controller. The controller controls the movement of the air guide assembly by driving the movement driving device, so as to achieve the effect that the air follows the user.

[0066] Further, the air outlet system is further provided with a crowd identification device capable of automatically identifying the user group. The crowd identification device and the fan are electrically connected with the controller. The crowd identification device can be a camera or a sound device for crowd identification. According to the user group mode to which the user belongs identified by the crowd identification device, the user group mode includes an old person mode, a child mode and an adult mode, and the adult mode includes a female adult mode and a male adult mode. Because the physiological metabolism of different user group modes is different, for example, the physiological metabolism of old people and children is very different, the controller can adjust the air outlet speed and the air outlet temperature of the fan according to the user group mode to which the current user belongs, so as to achieve that the users of different user group modes can experience the best comfortable temperature. Because the physiological metabolism of different user group modes is different, the best comfortable temperature of different user groups is also different. For example, under the same air speed, the best comfortable temperature of the female adult mode is Tf, the best comfortable temperature of the old person mode is Ts, the best comfortable temperature of the child mode is Tk, and the best comfortable temperature of the male adult mode is Tm. Tf>Ts>Tk>Tm is required, so that the body temperature of different user groups is the most comfortable. The present application adds the crowd identification device, further increases the data collection of the air outlet system on the real-time situation of the user, so as to increase the adjustment parameters of the air outlet system, and further makes the air outlet system more personalized and most comfortable for different user groups.

[0067] In addition, the user group mode can be stored in the memory of the controller in advance. The user can operate the product user terminal to call the user group mode corresponding to the current user, and then the air outlet system adjusts the corresponding air outlet speed and air outlet temperature.

[0068] Further, the air outlet system is further provided with a state recognition device capable of automatically recognizing the state of the user, and the state recognition device and the fan are electrically connected with the controller. The current state of the user can be a leisure state, a working state or a strong labor state, wherein the leisure state is defined as a relaxed sitting posture, no physical activity and light mental activity, such as reading, watching mobile phones, watching movies, etc.; the working state is defined as an upright sitting posture, light physical activity and strong mental activity, such as writing articles, data analysis, etc.; the strong labor state is defined as a standing posture and strong physical activity, such as walking, doing housework, etc.; according to the state recognized by the state recognition device, the controller adjusts the air outlet speed and the air outlet temperature of the fan. The user can be in different states, even the same user, because the activity intensity and metabolic intensity are different, so as to achieve the best comfortable temperature felt by the user, the air outlet system needs to automatically adjust the air outlet speed and the air outlet temperature of the fan. For example, in the leisure state, the most comfortable temperature in the space is Tr; in the working state, the most comfortable temperature in the space is Tw; in the strong labor state, the most comfortable temperature in the space is Ti, wherein Ti < Tw < Tr is set, so that the user's thermal sensation temperature is the most comfortable. The state recognition device is added in the application, which further increases the data collection of the air outlet system on the real-time situation of the user, thereby increasing the adjustment parameters of the air outlet system, and further enabling the air outlet system to make more personalized and comfortable intelligent air sensing adjustment according to the different states of the user.

[0069] In addition, the different states of the user can be stored in the memory of the controller in advance, and the user can operate the product user terminal to call out the state conforming to the current user, and then the air outlet system adjusts the corresponding air outlet speed and air outlet temperature.

[0070] Further, the air outlet system is provided with an environment sensing device capable of sensing the temperature and humidity of the surrounding air environment, and the environment sensing device and the fan are electrically connected with the controller. According to the temperature and humidity of the surrounding air sensed by the environment sensing device, the controller adjusts the air outlet speed and the air outlet temperature of the fan. The environment sensing device further increases the parameters of intelligent air sensing adjustment, and the more air adjustment parameters can more truly reflect the real situation of the user, so that the air blown out after the adjustment of the air blowing system is closer to the best thermal sensation of the user, which provides the user with more intelligent, scientific and comfortable experience.

[0071] In addition, the parameters of the space environment temperature and humidity can be stored in the memory of the controller in advance, and the user can operate the product user terminal to call out the parameters conforming to the current space environment, and then the air outlet system adjusts the corresponding air outlet speed and air outlet temperature.

[0072] To sum up, the intelligent sensing adjustment method of the application can intelligently collect corresponding data according to different user groups, different states of the users, different positions of the users and different spatial environments of the users, so as to control the air guiding assembly and the fan of the air supply system to realize the adjustment of the wind flow direction, wind speed and temperature, and further provide the user with more intelligent, scientific and comfortable air blowing experience.

[0073] In the present embodiment, the collection, uploading, storage and downloading of various user real-time data and the driving of the operation of the fan and the air guiding assembly of the air supply system all rely on the existing software and hardware, which will not be described here.

[0074] The technical means disclosed in the present application scheme is not limited to the technical means disclosed in the above embodiments, but also includes the technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary skilled persons in the art, without departing from the principle of the present application, some improvements and refinements can be made, which are also considered as the protection scope of the present application.
