[0036] Referring to Figures 1-7 An embodiment of the present application provides a fan module 10, which comprises a housing assembly 100 and a fan wheel assembly 200 disposed in the housing assembly 100; the housing assembly 100 is provided with at least a first air outlet 131 and a second air outlet 141, and the housing assembly 100 is provided with at least a first air outlet passage 130 and a second air outlet passage 140; a first end of the first air outlet passage 130 is connected to the fan wheel assembly 200, the first air outlet 131 is located at a second end of the first air outlet passage 130, a first end of the second air outlet passage 140 is in communication with the first air outlet passage 130, and the second air outlet 141 is located at a second end of the second air outlet passage 140; the first air outlet 131 is configured to blow air along a first direction, the second air outlet 141 is configured to blow air along a second direction, and the first direction is arranged at an angle to the second direction.

[0037] In this way, when the fan wheel assembly 200 rotates, the airflow flows along the first air outlet passage 130 to directly pass through the first air outlet 131 to blow air, or at least part of the airflow flows along the first air outlet passage 130 into the second air outlet passage 140 to blow air through the second air outlet 141, and the first direction is arranged at an angle to the second direction. That is, through the air guiding effect of the first air outlet passage 130 and the second air outlet passage 140, the airflow can be guided to different directions through the first air outlet 131 and the second air outlet 141 respectively, so as to increase the blowing range of the fan module 10.

[0038] Specifically, the angle between the first direction and the second direction can be any value in the range of 0-180 degrees. For example, when the cooking bench is arranged close to the wall, the first direction is perpendicular to the second direction, the first direction is the front of the cooking bench, and the second direction is the side of the cooking bench; or when the cooking bench is not arranged close to the wall, the angle between the first direction and the second direction is greater than 145 degrees, the first direction is the front of the cooking bench, and the second direction is the right rear of the cooking bench.

[0039] Further, the fan module 10 comprises a stop structure arranged at the first end of the second air outlet channel 140, and the stop structure is used to change the direction of at least part of the airflow so as to flow into the second air outlet channel 140 from the first air outlet channel 130.

[0040] In this way, when the fan wheel assembly 200 rotates, the airflow first enters the first air outlet channel 130, and then changes direction under the blocking action of the blocking assembly, so as to enter the second air outlet channel 140 and blow out from the second air outlet 141 along the second direction. That is, the present application does not need to add an additional fan wheel assembly, but only by changing the direction of the airflow, the blowing range can be increased.

[0041] In other embodiments, the stop structure can also not be arranged, and a fan wheel assembly can be arranged at the first end of the second air outlet channel to change the direction of the airflow in the first air outlet channel.

[0042] Further, the shell assembly 100 comprises an outer shell 110, the outer shell 110 has a front wall 111 and at least one side wall 112 connected with the front wall 111, the first air outlet 131 is located on the front wall 111, and the second air outlet 141 is located on the side wall 112.

[0043] In this way, when the user works on the side of the fan module 10, a part of the airflow blows out from the second air outlet 141 on the side wall 112 towards the side through the second air outlet channel 140, thereby achieving cooling of the side. That is, the fan module 10 of the present application not only can blow air towards the front, but also can blow air towards the side, thereby improving the comfort experience of the user.

[0044] Among them, the number of side walls 112 can be one or two, and the left and right sides of the front wall 111 are respectively provided with side walls 112, and the second air outlets 141 are respectively arranged on the two side walls 112. For example, when the user works on the left and right sides of the cooking bench, the two air outlets on the left and right sides can respectively blow air. That is, the present application can achieve 270-degree wide-range blowing, and the blowing effect is good.

[0045] Among them, the front wall 111 is parallel to the axis of the fan wheel assembly 200, and the front wall 111 is located at one end of the fan wheel assembly 200 along the first direction.

[0046] Further, the front wall 111 is parallel to the axis of the wind wheel assembly 200, and the front wall 111 is located at one end of the wind wheel assembly 200 in the first direction, that is, the wind wheel assembly 200 mainly blows out through the first air outlet 131 on the front wall 111. Since the temperature in front of the cooking table is the highest, the wind wheel assembly 200 mainly blows out through the first air outlet 131 on the front wall 111, which ensures that the user can get better cooling effect when operating in front of the cooking table.

[0047] Specifically, the front wall 111 has side walls 112 on opposite sides, and the second air outlets 141 on the two side walls 112 have opposite air outlet directions; the wind wheel assembly 200 includes two wind wheels 210 spaced apart in the second direction by a support, and each second air outlet 141 is in communication with a wind wheel 210 through a corresponding second air passage 140.

[0048] Among them, the fan module 10 includes two coaxially arranged wind wheels 210, and the wind wheel 210 can be a cross-flow fan blade. The cross-flow fan blade has the characteristics of soft wind, weak wind feeling and uniformity, and is more comfortable than an axial flow fan in close-range use. The two wind wheels 210 are provided with a support, and the support is provided with a double-shaft motor 220, and the double-shaft motor 220 is connected with the two wind wheels 210 at the same time, and is used to drive the left and right two wind wheels 210 to rotate at the same time. The two wind wheels 210 are spaced apart by the support, that is, the left and right two second air passages 140 are not communicated, and the air outlet directions of the second air outlets 141 on the two side walls 112 are opposite, one of the second air outlets 141 is located at the left end of the corresponding second air passage 140, and the other second air outlet 141 is located at the right end of the corresponding second air passage 140, so that the left and right ends of the fan module 10 are both divided to blow out air.

[0049] In combination Figures 5-6 In some embodiments of the present application, the stop structure includes a front panel 120 movably arranged on the shell 110, and the front panel 120 is used to close or open the first air outlet 131. When the first air outlet 131 is closed, the front panel 120 is used to make the airflow in the first air passage 130 flow into the second air passage 140.

[0050] In this way, on the one hand, when the first air outlet 131 does not need to blow out air, the front panel 120 closes the first air outlet 131, which improves the appearance of the fan module 10 and prevents the first air outlet 131 from being dusty or polluted by oil fume. On the other hand, when the front panel 120 closes the first air outlet 131, the front panel 120 is used to block the first air outlet 131. At this time, the air blown out from the wind wheel 210 can be deflected to the second direction under the blocking action of the front panel 120, so as to blow out from the second air outlet 141, thereby ensuring the air volume of the second air outlet 141 when only the second air outlet 141 is opened.

[0051] In some embodiments, in combination with Figure 2 The front panel 120 is capable of moving in a vertical direction relative to the shell 110. The shell is provided with support plates 123 on both sides close to the left and right side walls 112, and the support plates 123 are provided with lifting motors 122 for driving the linkage assemblies 121 to rotate to drive the front panel 120 to lift and lower. When the linkage assemblies 121 rotate, the front panel 120 is driven to move upwards, thereby opening the first air outlet 131, and when the linkage assemblies return to the original position, the front panel 120 is driven to move downwards, thereby closing the first air outlet 131. The support plates 123 are provided with through holes 124 for allowing the second air outlet channel 140 to communicate with the outside.

[0052] In some other embodiments, the front panel can be rotatably connected to the shell, for example, the upper portion of the front panel is provided with a rotating shaft extending in the second direction, both ends of the rotating shaft are rotatably connected to the shell, and the shell is provided with a motor for driving the front panel to rotate. When the front panel is rotated to a horizontal position, the first air outlet is opened, and when the front panel is rotated to a vertical position, the first air outlet is closed.

[0053] In some embodiments of the present application, the stop structure comprises a sweeping assembly 300, both ends of the sweeping assembly 300 in the second direction are rotatably connected to the shell, and the sweeping assembly 300 is located in the first air outlet 131. When the sweeping assembly 300 rotates, it is used for sweeping air in the up-down direction to increase the air outlet range of the first air outlet 131 in the vertical direction.

[0054] Further, in combination with Figure 6 and Figure 7 The sweeping assembly 300 comprises at least two sweeping plates 310 parallel to each other, both ends of the at least two sweeping plates 310 in the second direction are rotatably connected to the shell; when the sweeping plates 310 are parallel to the front panel 120, the sweeping assembly 300 is closed, and the sweeping plates 310 are used to make part of the airflow in the first air outlet channel 130 flow into the second air outlet channel 140; when the sweeping plates 310 are inclined or perpendicular to the front panel 120, the sweeping assembly 300 is opened.

[0055] In combination with Figure 6 When the first air outlet 131 is closed, the sweeping assembly 300 is closed, at this time the sweeping plates 310 are parallel to the front panel 120, that is, the sweeping plates 310 are in a vertical position, which is used to prevent the front panel 120 from interfering with the sweeping plates 310 when the front panel 120 is closed. In combination with Figure 7When the first air outlet 131 is opened, the air sweeping assembly 300 is opened, and when the air guide assembly rotates, the air sweeping plate 310 is driven to rotate, thereby changing the direction of the air flow. At the same time, when the first air outlet 131 and the second air outlet 141 are opened, the air sweeping plate 310 can be closed to stop part of the air flow through the air sweeping plate 310, so that part of the air flow is blown out from the second air outlet 141 in the second direction, and part of the air flow is blown out from the gap between the air sweeping plate 310 and the first air outlet 131 in the first direction, thereby realizing the air outlet of the first air outlet 131 and the second air outlet 141 at the same time.

[0056] Of course, the fan module 10 also includes a left-right air guide assembly, which is arranged at one end of the first air outlet 131 close to the fan wheel 210, that is, simultaneously located in the first air outlet channel 130 and the second air outlet channel 140, which is used to realize the left-right air sweeping of the first air outlet 131. On the other hand, when the air outlet through the second air outlet 141 is needed, the left-right air sweeping assembly 300 is used to guide part of the air flow of the fan wheel 210 to the left-right second air outlet 141, thereby enhancing the air volume of the second air outlet 141.

[0057] In some embodiments of the present application, the fan module 10 has a front air outlet mode and a side air outlet mode. When the fan module 10 is in the front air outlet mode, the front panel 120 moves to open the first air outlet 131, the air sweeping assembly 300 is opened, and the fan wheel assembly 200 is opened. Figure 3 When the fan module 10 is in the side air outlet mode, the front panel 120 moves to close the first air outlet 131, the air sweeping assembly 300 is closed, and the fan wheel assembly 200 is opened.

[0058] Further, in combination with Figure 4 The fan module 10 has a front side air outlet mode. When the fan module 10 is in the front side air outlet mode, the front panel 120 moves to open the first air outlet 131, the air sweeping assembly 300 is closed, and the fan wheel assembly 200 is opened.

[0059] In combination with Figure 1 In some embodiments of the present application, the fan module 10 further includes a controller and a human body sensing sensor 500, and the human body sensing sensor 500 is arranged on the shell assembly 100. The controller is used to control the air outlet of the first air outlet channel 130 and / or the second air outlet channel 140 according to the detection signal of the human body sensing sensor 500.

[0060] The controller can be a microprocessor or an ASIC. The human body sensing sensor 500 can be a pyroelectric infrared sensor, an ultrasonic sensor, and a microwave radar sensor.

[0061] Specifically, the human body sensor 500 is arranged at the connection position of the front wall 111 and the side wall 112, so as to detect whether the human body is located in the front area or the side area.

[0062] Of course, the human body sensor 500 can also be arranged on the front wall 111 and the side wall 112 respectively, and the human body sensors 500 arranged on the front wall 111 and the side wall 112 are simultaneously connected with the controller.

[0063] In combination Figure 2 In some embodiments, the fan module 10 further comprises an air outlet assembly 400 mounted in the first air outlet channel 130, and the air outlet assembly 400 can be a grille for safety protection.

[0064] The control method of the fan module 10 comprises the following steps:

[0065] Turning on the front blowing mode;

[0066] Determining whether the area where the human body is located is the front area or the side area, if the area is the front area, maintaining the front blowing mode, and if the area is the side area, determining whether the time length ratio P in the side area is greater than or equal to a first preset time length ratio N.

[0067] If the time length ratio P in the side area is greater than or equal to the first preset time length ratio N, turning off the front blowing mode and turning on the side blowing mode, wherein the time length ratio refers to the ratio of the total time length of the area to the total running time length.

[0068] Specifically, when the fan module 10 is in the front blowing mode, the front panel 120 is opened, the air sweeping assembly 300 is turned on, and the fan wheel 210 is rotated; when the fan module 10 is in the side blowing mode, the front panel 120 is closed, the air sweeping assembly 300 is turned off, and the fan wheel 210 is rotated.

[0069] Specifically, before the front blowing mode is turned on, the program self-checking is further included, which is to judge whether the operation is normal through current abnormality or other ways. If the program self-checking is normal, the subsequent steps are performed, and if the program self-checking is abnormal, the machine is directly turned off.

[0070] In use, after the user turns on the fan, first, the program self-checking is performed, after the self-checking is normal, the front blowing mode is opened, in the front blowing mode, the front panel 120 is opened, the air sweeping assembly 300 is opened, the fan wheel 210 rotates, that is, the air blown out from the fan wheel 210 can be blown out from the first air outlet 131 through the air sweeping assembly 300. In this process, the human body sensing sensor 500 detects the area where the human body is located, if it is detected that the human body is always in the front area, the front blowing mode is maintained; if it is detected that the human body is in the side area, it is judged that the time length ratio P of the human body in the side area; wherein the time length ratio P in the side area is the cumulative time length in the side area divided by the total running time, the time length ratio Q in the front area is the cumulative time length in the front area divided by the total running time, if the time length ratio P in the side area is greater than or equal to the first preset time length ratio N, the front air outlet mode is closed, and the side air outlet mode is opened; wherein the first preset time length ratio N is preset in the controller, the first preset time length ratio N > 50%, for example, the first preset time length ratio N is 60%, 70%, 80%.

[0071] For example, when the human body sensing sensor 500 detects that the human body is in the side area, and the time length ratio P in the side area is greater than or equal to 60%, it means that the human body is in the side area most of the time, at this time, the air sweeping blade is closed, the panel is lowered and closed, and the fan wheel 210 keeps normal operation. When the air flow passes through the air outlet, it is sealed and blocked by the front panel 120, and at the same time, the air sweeping blade is in the vertical position, the air flow passes through the air sweeping blade and is blown out through the left and right side air outlets, realizing blowing and cooling at positions other than the front of the range, satisfying the user to effectively cool the position in the preparation process before cooking and the position after cleaning, and improving the use efficiency and experience effect of the fan module.

[0072] Further, the control method further comprises:

[0073] If the detected area where the human body is located is the side area, and the time length ratio P in the side area is less than the first preset time length ratio N;

[0074] Then, it is judged whether the time length ratio P of the human body in the side area and the time length ratio Q of the human body in the front area are both greater than the second preset time length ratio 1-N, if yes, the front and side blowing modes are opened at the same time; if not, only the front blowing mode is maintained; wherein, in the front and side blowing mode of the fan module 10, the front panel 120 is opened, the air sweeping assembly 300 is closed, the fan wheel 210 rotates, and the sum of the first preset time length ratio N and the second preset time length ratio 1-N is 1.

[0075] For example, if the time length ratio of the human body in the front area and the side area is greater than 40%, it indicates that the human body moves back and forth in the front area and the side area, and the front and side blowing modes can be started at the same time. Specifically, the air sweeping plate 310 rotates parallel to the front panel 120, the panel is opened, and the air sweeping plate 310 stops part of the airflow, so that part of the airflow is blown out from the second air outlet 141 in the second direction, and part of the airflow is blown out from the gap between the air sweeping plate 310 and the first air outlet 131 in the first direction, thereby realizing front and side blowing at the same time.

[0076] Further, the side area includes a left side area and a right side area, and the side blowing mode includes a left side blowing mode and a right side blowing mode. The time length ratio of the human body in the left side area and the right side area can be determined by the above method to start the left side blowing mode and the right side blowing mode respectively.

[0077] It should be noted that the two shafts of the double-shaft motor 220 can be controlled separately. When the human body is in the left side area of the cooking head for a long time, such as preparing food or washing dishes, the left motor shaft can be started alone to drive the left cross-flow fan blade to rotate to realize left side blowing, thereby reducing energy consumption and noise. Similarly, when the human body is in the right side area for a long time, the right motor shaft can be started alone to drive the right cross-flow fan blade to rotate to realize right side blowing.
