Description

Technical Field

[0001] The present application relates to the field of fans, and in particular to a fan and a control system. Background Art

[0002] At present, indoor heating equipment includes floor heating, air conditioning, fan heater, electric oil heater, small solar heater, etc. Among them, floor heating is used to achieve heating from the ground throughout the house; after the cold air in the house goes down, it is heated by the floor heating and then naturally convects upward, so the temperature difference between the upper and lower parts of the room is small.

[0003] However, for heating equipment with limited or no wind coverage, such as air conditioners, small solar heaters, electric fan heaters, and electric oil heaters, the heated air in the room will run upwards, and the cold air below will be difficult to be heated, resulting in a large temperature difference between the upper and lower spaces. Therefore, people's intuitive feeling is that their faces are red and hot, and their feet are cold. If the ground is to be heated to a comfortable temperature, the temperature of the high ceiling is often much higher than the ground, resulting in a waste of electricity.

[0004] Conventional indoor fans have poor airflow concentration, high air inlet, and air outlet direction, all of which make it difficult for the fan to transfer cold air from the ground to the ceiling. As a result, the improvement in vertical air circulation is not obvious, and the problem of large temperature differences in the vertical direction cannot be solved.

[0005] Therefore, it is necessary to provide a fan that is easy to install indoors, has a high airflow concentration, and the air inlet height can be flexibly set, which can improve the vertical air circulation in the room, effectively reduce the temperature difference in the vertical direction, and save space. Summary of the invention

[0006] The embodiment of the present application provides a fan that is easy to install indoors and has a high degree of airflow concentration, which can improve the vertical air circulation in the room, effectively reduce the temperature difference in the vertical direction, and save space.

[0011] In the present application, the air outlet of the fan is arranged to extend along the length direction of the fan and guide the air in the vertical direction. In this way, the air outlet can be arranged in a long strip shape. When the fan is arranged close to the wall, the boundary layer effect limits the airflow range, so that the airflow is highly concentrated. When the air inlet is arranged close to the ground, it is beneficial to transport the cold air below the room into the fan, and then guide it through the air outlet and upward along the wall, so as to achieve vertical wind in the space close to the wall, which can effectively transmit the cold air on the ground to the ceiling and promote vertical air circulation; enhance the user experience; and the air outlet extends along the length direction of the fan, so that the fan does not take up space, and at the same time improves the effect of the boundary layer effect.

[0019] In some optional embodiments, the fan blades are cross-flow blades; the cross-flow blades extend along the length direction of the fan.

[0020] Compared with other fan blades, the cross-flow fan blades have higher airflow concentration, which further improves the airflow concentration and effectively transmits the indoor floor cold air to the ceiling, improving the user experience.

[0021] In some optional embodiments, the radius of the cross-flow blade is smaller than the length of the volute tongue portion of the fan.

[0022] In some optional embodiments, the first side wall of the shell is configured as a hole wall of the air outlet, and the length direction of the fan is parallel to the first side surface where the first side wall is located.

[0029] A fan is arranged at the first high point, with an air outlet of the fan facing the second high point, and the fan is the fan described in any one of the above embodiments.

[0030] The control system in the present application measures the near-ground temperature of the fan (i.e., the temperature at the first height) through the first sensor module, and measures the high temperature (the temperature at the second height) through the second sensor module, and controls the operating parameters of the above-mentioned fan according to the temperature difference between the two heights to achieve vertical convection.

[0031] In some optional embodiments, the operating parameter includes the power of the driving device of the fan;

DETAILED DESCRIPTION

[0054] The technical scheme of the embodiment of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, not all of the embodiments. Based on the embodiments in the embodiment of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the embodiment of the present application.

[0055] The term "one embodiment" or "embodiment" as referred to herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the embodiment of the present application. In the description of the embodiment of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the embodiment of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiment of the present application. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may include one or more of the features explicitly or implicitly. Moreover, the terms "first", "second", etc. are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the embodiment of the present application described here can be implemented in an order other than those illustrated or described here.

[0056] See also Figure 1-Figure 9 , the following describes another specific embodiment of a fan provided by the present application. The present application embodiment provides a fan 1, which includes a housing 11, fan blades 12 and a driving device 13. For the convenience of description, Figure 1 and Figure 4 Coordinate axes are established, namely, mutually perpendicular X-axis, Y-axis and Z-axis, wherein the X-axis is the length direction of the fan 1, the Y-axis is the width direction of the fan 1, and the Z-axis is the height direction of the fan 1.

[0057] See also Figure 1-Figure 3 In some optional embodiments of the present application, an air inlet 111 and an air outlet 112 are provided on the shell 11. The air outlet 112 is provided on the top side of the shell 11 (i.e., the top side along the height direction Z of the fan 1) and extends along the length direction X of the fan, and is used to guide wind in the height direction Z of the fan 1; the fan blades 12 are provided in the internal space of the shell 11; the driving device 13 is provided in the shell 11 and connected to the fan blades 12, and is used to drive the fan blades 12 to rotate, so that the gas is input into the shell 11 from the air inlet 111 and output from the air outlet 112.

[0058] In the present application, the air outlet 112 of the fan 1 is set to extend along the length direction X of the fan and guide the air in the height direction of the fan 1. In this way, the air outlet can be set in a long strip shape. When the fan 1 is set close to the wall, due to the boundary layer effect, the air flow range is limited, so that the air flow is highly concentrated. When the air inlet is set close to the ground, it is beneficial to transport the cold air below the room into the fan, and then export it through the air outlet 112 and upward along the wall Q, forming a wind curtain that partially goes upward along the wall, thereby realizing that there will be vertical wind in the space close to the wall, which can effectively transmit the cold air on the ground to the ceiling, promote vertical air circulation; improve the user experience; and the air outlet extends along the length direction of the fan, so that the fan does not occupy space, and at the same time improves the effect of the boundary layer effect. For example, the above-mentioned fan 1 is set in the corner of the wall, and by blowing the cold air on the ground along the wall to the ceiling, the "boundary layer flow" effect is used to limit the cold air to the "boundary layer", and the human body does not feel the cold wind; and the air outlet 112 extends along the length direction X of the fan, so that the fan 1 does not occupy space, and improves the effect of the boundary layer effect.

[0059] In some optional embodiments, the first side wall 113 of the housing 11 is configured as a hole wall of the air outlet 112 , and the length direction X of the fan is parallel to the first side surface where the first side wall 113 is located.

[0060] Specifically, Figure 5 and Figure 8As shown, one side of the air outlet 112 is the first side wall 113 of the housing 11 ; the fan 1 is installed with the first side wall 113 close to the wall. Wind is guided to the air outlet 112 from the channel between the fan blades 12 and the first side wall 113 .

[0061] like Figure 5 As shown, the first side wall 113 at the air outlet 112 is inclined toward the direction close to the wall surface, so that the air outlet direction is inclined toward the direction close to the wall surface.

[0062] In the above embodiment, the air outlet 112 is parallel to the first side surface. Thus, when the first side surface is arranged near a wall surface, the wind flow can be effectively directed toward the wall surface, a boundary layer can be effectively formed, and indoor space can be saved.

[0063] In some optional embodiments, the second side wall 117 of the shell 11 is provided with an air inlet 111 , and the second side wall 117 is arranged on a side of the fan blade 12 away from the first side wall 113 .

[0064] In some optional embodiments, the second side wall 117 is a curved side wall and extends along the length direction Y of the fan, and the second side wall 117 is disposed on the outer side of the fan blade 12 .

[0065] In some optional embodiments, the air inlet 111 is formed by at least one through hole on the second side wall 117. When a plurality of through holes are provided on the extended surface of the second side wall 117, it is convenient to make the wind speed at the air outlet uniform.

[0066] In some optional embodiments, the housing 11 has a top plate 118 at the top along the height direction Z of the fan to limit the width of the air outlet 112 .

[0067] In some optional embodiments, the housing 11 is provided with end housings 114 at both ends along the extension direction of the fan, and the end housings 114 are connected to the top plate 118, the first side wall 113, and the two ends of the second side wall 117; the bottom of the first side wall 113 is a curved side wall, and is connected to the bottom of the fan 1 and the second side wall 117. A bottom plate can also be provided at the bottom of the fan 1 to make the bottom surface flat for easy placement of the fan.

[0068] In some optional embodiments, the second side wall 117 (not shown in the figure) can be a flat plate structure, and the fan 1 is provided with a bottom plate ( Figure 4-Figure 6 (not numbered in the figure).

[0069] In some optional embodiments, a foot support 116 is provided at the bottom of the housing 11 for supporting the fan 1. The foot support 116 is provided on the bottom plate of the fan.

[0070] In some optional embodiments, the fan blades 12 are cross-flow fan blades; the cross-flow fan blades extend along the length direction of the fan.

[0071] In some optional embodiments, one end of the fan blade 12 is fixed to the rotating shaft of the driving device 13 , and the other end of the fan blade 12 is rotationally connected to the shell 11 ; the fixed end of the driving device 13 is fixed to the inner side of the end shell 114 .

[0072] In the above embodiment, Figure 6 As shown, the wind flow is directed toward the wall Q through the outlet direction of the air outlet 112, and the wall is effectively used to form a "boundary layer flow", so that the high-speed cold air is confined within the "boundary layer B", away from the wall without wind feeling, forming a boundary layer effect; the maximum wind speed line D to the wall Q is the wind deceleration area D1.

[0073] In some optional embodiments, the air outlet is inclined toward the width direction of the fan, and the width direction of the fan is perpendicular to the length direction of the fan.

[0074] Please refer to Figure 8-Figure 9 In some optional embodiments, the angle between the air outlet direction F of the air outlet 112 and the height direction Z of the fan 1 is less than or equal to 30 degrees.

[0075] In some optional embodiments, the air outlet direction of the air outlet 112 is inclined toward the wall, and the inclination angle is less than or equal to 30°.

[0076] In some optional embodiments, the air outlet direction of the air outlet 112 is inclined in a direction away from the wall, and the inclination angle is less than or equal to 30°.

[0077] In the above embodiment, the air outlet direction is adjusted to change the direction of the wind flow, so that the fan can be placed on a desktop or other furniture to increase usage scenarios and functions.

[0078] In order to facilitate the adjustment of the air outlet direction of the air outlet 112, some optional embodiments, please refer to Figure 1-Figure 3 , Figure 7-Figure 9 The air outlet 112 is provided with an air guide plate 115, and the air guide plate 115 is used to adjust the air outlet direction.

[0079] According to the usage scenario, the direction of the air guide plate 115 is set to adjust the outlet direction of the airflow from the air outlet 112. At the same time, the air guide plate 115 can also improve the concentration of the air discharged from the air outlet 112, so that the fan can be used in different usage scenarios to form an effective boundary layer.

[0080] In some optional embodiments, the number of the air guide plate 115 is at least one.

[0081] In some optional embodiments, there are multiple air guide plates 115, each of which extends along the length direction X of the fan, and is installed on the shell on both sides of the air outlet along the length direction of the fan; each of the air guide plates can rotate independently relative to the shell 11.

[0082] Specifically, there are two air guide plates 115, and both ends of each air guide plate 115 can be fixed to the housing on both sides along the length direction of the fan by bolts. By installing the air guide plate at the air outlet, space is saved, air is effectively guided, the concentration of air discharged from the air outlet is enhanced, and the air outlet direction can be adjusted.

[0083] In some optional embodiments, the air guide plate 115 may be Figure 1-Figure 3 The diamond-shaped wind guide blades and / or Figure 7-Figure 9 The lath-shaped blades shown.

[0084] It should be noted that, in some optional embodiments, the structure of the air guide plate is not limited, and other structures can be used to adjust the air outlet direction and the concentration of the air discharged from the air outlet.

[0085] The fan 1 has an air passage formed by the first side wall 113 and the volute tongue. Figure 3 As shown in the figure, ① is the radius of the crossflow blade; ② is the length of the volute tongue in the air outlet direction. The farthest distance from the volute tongue port to the center of the crossflow blade is ①+②. For conventional volute tongues, the size of ② must be larger, otherwise the air outlet concentration will be poor.

[0086] Generally, under the same or similar structure and rotation speed, the larger the diameter of the crossflow fan blade, the greater the wind. In some optional embodiments of the present application, the distance ① is much smaller than the distance ②, so that the height of the fan that discharges air in the vertical direction can be compressed to a very low level, or in other words, a crossflow fan blade with a larger diameter can be placed within a limited height, thereby reducing the volume of the fan, saving the space occupied by the fan, and reducing noise.

[0087] For example, if the diameter of the cross-flow fan blade is 9 cm, the overall height of the fan can be 10.5 cm; the fan can be placed under a sofa or radiator at a height of more than 10.5 cm from the ground.

[0088] refer to Figure 1-Figure 3 In some optional embodiments, the number of diamond-shaped air guide blades is two, and the air guide plate 115 disposed below the plane of the air outlet 112 is a diamond-shaped air guide blade, and the lowest point of the diamond-shaped air guide blade is lower than the highest point of the blade. For example, the center of the crossflow blade or a part of the crossflow blade is lower than the highest point of the crossflow blade in the height direction of the fan.

[0089] In the above embodiment, the diamond-shaped air guide blades and the housing 11 are used to divide the airflow twice. Figure 3As shown, there are two air guide plates 115 at the air outlet, and airflow 1 is divided into airflow 2 and airflow 3 by the air guide plate 115 close to the fan blade 12, wherein airflow 2 flows vertically upward from between the two air guide plates 115, and airflow 3 is divided into airflow 4 and airflow 5 by the housing 11 and the air guide plate 115 close to the fan blade 12, and airflow 4 flows vertically upward, and airflow 5 flows to the left into the housing 11. Since airflow 3 is divided and has a low flow rate, the noise generated when it is further divided into airflow 4 and airflow 5 by the housing is very small.

[0090] In some optional embodiments, the length of the shell 11 in the length direction X of the fan is greater than the length of the shell 11 in the width direction Y of the fan. It is convenient to set the fan close to the wall or furniture and other structures, which can effectively form a boundary layer and save the user's use space. Usually due to the operating principle of indoor refrigeration or heating equipment, when the refrigeration or heating equipment runs for a long time, it will cause the indoor air to dry, and the existing humidification devices are mainly divided into two types. The first is based on an ultrasonic atomizer, which atomizes liquid water into small water droplets and floats away. The second is to humidify the air by natural evaporation by heating or increasing the contact area between water and air, accelerating air flow. Although the first solution has a fast humidification speed, small water droplets that have not been fully vaporized will cause local moisture. The second solution has a slower humidification speed and higher power consumption.

[0091] See also Figure 4-Figure 9 In some optional embodiments, the fan 1 further includes a humidifying device 14 , which is disposed on the top side of the housing 11 and adjacent to the air outlet 112 .

[0092] In this embodiment, by arranging the humidifier 14 close to the air outlet 112, the humidified air can be introduced into the boundary layer, the circulating air can be humidified, and as the air flows, the effect of humidifying the air in the entire indoor space can be achieved, while avoiding the problem of local humidity; and avoiding the fan 1 or the humidifier 14 from occupying more indoor activity space.

[0093] In some optional embodiments of the present application, the water mist outlet 141 on the humidifying device 14 is installed between the boundary layer and the maximum wind speed line; the boundary layer is the boundary layer generated when the fan 1 is used close to a solid wall (such as a wall).

[0094] In this embodiment, the water mist outlet 141 is installed between the boundary layer B and the maximum wind speed line D, and the moist mist is confined therebetween, ensuring rapid vaporization without wetting the furniture and wall surface Q.

[0095] In some optional embodiments of the present application, the water mist outlet 141 and the air outlet 112 have the same orientation.

[0096] For example, Figure 5 and Figure 8As shown, the water mist outlet 141 and the air outlet 112 are both vertically upward to avoid wetting the wall surface and effectively limit the wet mist to the boundary layer. Figure 6 and Figure 8 As shown, the water mist S moves toward the maximum wind speed line D ( Figure 6 Shown) close.

[0097] In some optional embodiments of the present application, the humidifying device 14 further includes an atomizer 142 and a water tank 143 , and the atomizer 142 is disposed in the water tank 143 .

[0098] It should be noted that in some embodiments of the present application, there is no limitation on the type and structure of the humidifying device 14 , and other types of humidifying devices 14 may be used.

[0099] In some optional embodiments of the present application, the nebulizer 142 is an ultrasonic nebulizer.

[0100] In some optional embodiments of the present application, the water tank 143 extends along the length direction X of the fan.

[0101] In some optional embodiments of the present application, the water tank 143 is provided with a water inlet 144, and the water mist outlet 141 is provided at the water inlet 144. Figure 6 As shown, the water inlet 144 is provided with a cover plate (not numbered), a mist outlet pipe (not numbered) is provided on the cover plate, and a water mist outlet 141 is provided at the end of the mist outlet pipe.

[0102] In some optional embodiments of the present application, Figure 4-Figure 6 As shown, a humidifier 14 is provided on one side of the air outlet 112 away from the first side wall 113; the humidifier 14 includes a water tank 143, an ultrasonic atomizer is installed at the bottom of the water tank 143, and a water mist outlet 141 is directly above the ultrasonic atomizer, and the water mist outlet 141 passes through the water inlet 144. The water mist outlet 141 is provided between the boundary layer B and the maximum wind speed line D.

[0103] According to Bernoulli's principle, the higher the wind speed, the lower the pressure, so the slow water mist at the water mist outlet 141 will be attracted by the high-speed airflow and vaporize quickly. The air with water mist will be confined to the maximum wind speed line and the boundary layer, and will not wet the wall or other furniture.

[0104] See also Figure 4-Figure 6 In some optional embodiments, the side of the water tank 143 close to the inside of the shell 11 and the shell 11 together constitute the fan volute.

[0105] See also Figure 7-Figure 9 In some optional embodiments, the water tank 143 is square.

[0106] It should be noted that the present application does not impose any restrictions on the shape of the water tank.

[0107] In some optional embodiments, the fan blades 12 are crossflow fan blades 12; the crossflow fan blades 12 extend along the length direction of the fan. In this embodiment, the crossflow fan blades 12 are arranged inside the housing 11, and the wind flows out from the channel between the crossflow fan blades 12 and the first side wall 113 to the air outlet 112.

[0108] In some optional embodiments, the driving device 13 is a motor.

[0109] like Figure 4 , Figure 7 As shown, the driving device 13 is arranged at the end of the casing along the length direction of the fan.

[0110] In the above embodiment, the housing 11 (such as the first side wall 113) constitutes a windshield of the fan 1, and the shape of the water tank 143 and the housing 11 together constitute the fan volute. Driven by the motor, the crossflow blades 12 inhale the cold air in the lower space of the room and blow it upward at high speed.

[0111] In some optional embodiments, the fan 1 further includes a power connection device 16 and a control device 17 .

[0112] The power connection device 17 is used to connect an external power source to provide power to the fan; the control device 17 is used to control the operation of the driving device 13.

[0113] See also Fig.10 In some optional embodiments, the control device 17 includes at least one of a speed regulation module 171 , a single chip computer 172 , a Bluetooth module 173 , and a wifi module 174 .

[0114] In some optional embodiments, a first sensor 18 is provided at the air outlet 112 on the housing 11 .

[0115] In some optional embodiments, the first sensor 18 includes a first temperature sensor.

[0116] Specifically, the first temperature sensor is installed at the air outlet 112, and is used to measure the temperature of the air sucked into the bottom of the room, using high-speed airflow to achieve a rapid response, and transmit the temperature signal to the single-chip microcomputer.

[0117] In some optional embodiments, the first sensor 18 further includes a first humidity sensor.

[0118] In the above embodiment, the fan 1 collects the temperature and humidity data of the first sensor near the fan 1 through the single chip microcomputer 172, and sends the collected temperature and humidity data to an external control device (such as a mobile phone or remote control) through the Bluetooth module 173. The wifi module 174 of the fan 1 can also be used to access the indoor local area network and communicate with the mobile phone, and the mobile phone can be used to set various parameters (such as the switch of the fan 1 and the size of the wind speed). The fan 1 adjusts the power of the driving device through the speed control module, that is, adjusts the wind speed of the fan.

[0119] The following describes a specific embodiment of a control system provided by the present application. Figures 11A-11D , the present application provides a control system 700, including:

[0120] The first sensor module 701 is disposed at a first height in the room and is used to measure a first temperature at a first height;

[0123] The fan 1 is arranged at the first high position, and the air outlet of the fan faces the second high position.

[0124] Through the control system, the near-ground temperature of the fan (i.e., the temperature at the first height) is measured by the first sensor module, and the high temperature (the temperature at the second height) is measured by the second sensor module. According to the temperature difference between the two heights, the operating parameters of the above-mentioned fan are controlled to achieve vertical convection.

[0125] For example, when the ground temperature (temperature at the first height) is significantly lower than the ceiling temperature (temperature at the second height), it is judged that the external cooling or heating equipment is turned on; when the ground temperature is higher than the ceiling temperature, or the temperatures are almost the same, it is judged that the external cooling or heating equipment is turned off; when the system confirms that the cooling or heating equipment is turned on, fan 1 is turned on to promote vertical convection of indoor air; when the external cooling or heating equipment is turned off, fan 1 is turned off, and the control system can perform regular detection.

[0126] In some optional embodiments, the first sensing module 701 includes the first sensor 18 described above, and the second sensing module includes the second sensor.

[0129] In some optional embodiments, the second sensor can be installed near the ceiling indoors by sticking or hooking, with the solar panel facing the indoor light source, and the solar cell is used to charge the button battery facing the indoor light source.

[0130] The second sensor module 702 communicates with the fan 1 using Bluetooth 4.0. In energy-saving mode, the fan 1 communicates once every 10 minutes, requests communication once, and sends the temperature and humidity information of the ceiling. In normal mode, the fan 1 communicates once every 1 minute.

[0131] In some optional embodiments, the first sensor 18 may also be integrated into the power plug of the fan 1, and the same function may be achieved by detecting the temperature and humidity at the height of the power plug.

[0132] In some optional embodiments, the control module 703 includes a calculation submodule 7031 , a judgment submodule 7032 and a control submodule 7033 .

[0133] The calculation submodule 7031 is used to calculate the above-mentioned difference; the calculation submodule 7031 and the judgment submodule 7032 are used to calculate the difference; the judgment submodule 7032 is used to determine the power of the fan driving device based on the difference; and the control submodule 7033 is used to control the power of the fan.

[0134] In some optional embodiments, the determination submodule 7032 includes:

[0135] The first judgment module 70321 is used to determine that the operation state of the external heating device is the on state when the temperature difference is greater than a preset threshold;

[0136] The second judgment module 70322 is used to determine that the operation state of the external heating device is the off state when the temperature difference is less than a preset threshold;

[0137] The control submodule 7033 includes:

[0138] The fan on module 70331 controls the fan to be on when the operation state of the external heating device is on;

[0139] The fan closing module 70332 controls the fan to close when the operating state of the external heating device is closed.

[0140] In some optional embodiments, the fan is installed adjacent to an indoor wall, and the wind direction of the fan is vertically upward.

[0141] In some optional embodiments, the fan is arranged on the lower side of the external heating device in the vertical direction.

[0142] In some optional embodiments, the first sensing module is used to regularly measure the indoor near-ground temperature; the second sensing module is used to regularly measure the indoor near-ceiling temperature.

[0143] The present application provides a fan including a housing 11, a fan blade 12 and a driving device 13. The housing 11 is provided with an air inlet 111 and an air outlet 112. By arranging the air outlet 112 to guide air in a vertical direction and arranging the air outlet 112 on the top side of the housing 11 and extending along the length direction of the fan, the fan can be easily installed indoors and save space, and the vertical air circulation in the room can be improved.

[0144] In some optional embodiments, the operating parameters include the power of the driving device of the fan.

[0145] For example, the control module can be a mobile phone, a remote control or other device, and the user can set the power of the corresponding driving device in different temperature ranges through the device, so as to adjust the indoor air flow and humidity according to the user's needs.

[0146] The following is an example of a control system:

[0147] First, the user sets the target humidity through the phone;

[0148] Next, the user presets the relationship between temperature difference and motor power through the mobile phone.

[0149] For example, if the temperature difference is less than 2 degrees, the motor power is 30%; if the temperature difference is between 2 and 4 degrees, the motor power is 60%; if the temperature difference is between 4 and 6 degrees, the motor power is 80%; if the temperature difference is greater than 6 degrees, the motor power is 100%. The phone displays the temperature and humidity at the highest point, the temperature at the second highest point, and the real-time motor speed.

[0150] Finally, the humidifying device 14 is turned on or off at a scheduled time through the mobile phone.

[0151] The single chip microcomputer in the fan 1 determines the power of the driving device 13 based on the current temperature difference and the relationship between the preset temperature difference and the motor speed.

[0152] The single chip microcomputer is also used to control the motor power based on the target motor power sent by the mobile phone; and to control the on / off of the humidifying device 14 according to the switch command sent by the mobile phone.

[0153] The following is an exemplary description of an application scenario of the fan and control system provided by the present application. The fan and control system provided by the embodiment of the present application are used in indoor or outdoor spaces where vertical air circulation is required, which is not limited here.

[0154] Please refer to Fig.12 The air conditioner 2 is set at the second highest point in the room, and its wind coverage is limited; when heating or cooling, the temperature difference between the upper and lower spaces in the vertical direction of the room is large, especially when heating, after the heated air in the room (i.e., hot air R) runs upward, the cold air L below is difficult to be heated, resulting in a large temperature difference between the upper and lower spaces.

[0155] The fan provided in the present application can be set up indoors and close to the wall, forming a boundary layer effect at the wall to form vertical upward wind along the wall surface, thereby realizing air circulation in the vertical upper and lower spaces of the room. At the same time, the fan will not affect the user's experience, for example, the fan will not blow to the user, affecting the user's experience.

[0156] Above Fig.12 In the scene shown, the fan is set in the corner of the wall, which is only for the convenience of illustrating the role of the fan provided by the present application in promoting air circulation in the vertical direction, and is not used to limit the scope of use of the fan of the present application. The fan can be integrated into the furniture, and the same function should also be within the scope of protection. For example, the fan is installed on the back of the sofa; the fan is installed under the heating equipment such as the radiator to form a high-speed wind flow from the bottom to the top, so as to achieve rapid heating in the room; it can save space and will not affect the user's experience; the fan can also be hidden behind furniture such as TV cabinets and tables, or embedded in various types of furniture. It is small in size and basically does not take up indoor space.
