Description

Technical Field

[0001] The present invention belongs to the field of cleaning technology, and specifically relates to equipment for cleaning through airflow of a fan, and more particularly to an intelligent cleaning device and a cleaning method for a fan. Background Art

[0002] In animal husbandry, ventilation is an important factor in ensuring animal health and production performance. A good ventilation system can provide fresh air, regulate temperature and humidity, dilute pollutants, reduce disease transmission, and improve air quality, thereby ensuring animal health and comfort.

[0003] In the related art, since the density of animal breeding is relatively high and the requirements for air quality are relatively low, outdoor air can be directly used for ventilation. Therefore, when using a fan for ventilation, in order to ensure the air output of the fan, a filter will not be set at the air inlet of the fan, so as to ensure that the air output of the fan can meet the ventilation needs. After long-term use, a large amount of dust and dirt will accumulate on the fan blades, thereby changing the area of ​​the fan's air inlet and exhaust port, affecting the wind speed and wind pressure, and causing the fan's air output to decrease. The fan needs to be manually dismantled and cleaned regularly.

[0004] Therefore, how to clean the fan without dismantling the fan is a technical problem that needs to be solved urgently.

[0005] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Herein, when it is mentioned that a first component is located on a second component, this may mean that the first component may be directly formed on the second component, or a third component may be interposed between the first component and the second component.

[0025] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, in the drawings, the thickness of the components may be exaggerated or reduced in order to effectively describe the technical content.

[0026] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0027] See also Figure 1 and Figure 2 At least one embodiment provides an intelligent cleaning device for a fan 200, comprising: an air outlet duct 100; two stacked fans 200, which are arranged in the air outlet duct 100; a cleaning mechanism 300, which is arranged in the air outlet duct 100 and is located on the air outlet side of the two fans 200; a control module, which is electrically connected to the cleaning mechanism 300 and is configured to control the operation of the cleaning mechanism 300 according to the working state.

[0028] Specifically, the working status includes: In the first working state, when the fan 200 is stopped, the control module controls the cleaning mechanism 300 to block the air outlet duct 100. When the fan 200 is stopped, the air outlet duct 100 is blocked by the cleaning mechanism 300, thereby preventing external impurities from entering the room along the air outlet duct 100.

[0029] In the second working state, in winter, when the machine needs to be turned on, the control module is configured to first control the cleaning mechanism 300 to heat the air outlet pipe 100, then control the cleaning mechanism 300 to open the air outlet pipe 100, and control the two fans 200 to start, and complete the cleaning of the dirt in the air outlet pipe 100 through the airflow of the fans 200. It should be noted that the starting power of the fan 200 is relatively low, and the dirt in the air outlet pipe 100 will not be blown away directly. When collecting the dirt flowing out of the air outlet pipe 100, a dirt flow channel or a dirt collection frame is set according to the use requirements. At the same time, after the air outlet pipe 100 is heated, the dirt can be softened, thereby improving the cleaning effect.

[0030] In the third working state, when the machine is stopped, the control module is configured to detect the air volume of the two fans 200 through the cleaning mechanism 300 according to the preset time interval. When the air volume of the two fans 200 is inconsistent with the preset air volume, the two fans 200 are controlled to operate at different powers, and the dirt on the fans 200 is cleaned by the airflow of the fans 200. By setting two fans 200 for ventilation and setting the cleaning mechanism 300 to detect the air volume of the two fans 200, when it is detected that the air volume of the two fans 200 is inconsistent with the preset air volume, the two fans 200 are controlled to operate at different powers, so that the two airflows collide near the blades of the fan running at low power, generating violent turbulence, and better cleaning the blades of the fans 200, thereby realizing self-cleaning of the fans 200 and reducing the frequency and cost of manual cleaning.

[0031] It should be noted that Figure 1 The direction of the arrow F in the middle is the air outlet direction of the two fans.

[0032] See also Figure 3 and Figure 4 In some embodiments, the cleaning mechanism 300 includes: a mounting frame 310, which is embedded in the inner wall of the air outlet 100; a first heating plate 320 and a second heating plate 330, wherein the first heating plate 320 and the second heating plate 330 are arranged up and down and are arranged in the mounting frame 310; wherein the bottom of the first heating plate 320 is rotatably connected to the mounting frame 310 through a first rotating shaft 321, and the top of the second heating plate 330 is rotatably connected to the mounting frame 310 through a second rotating shaft 331; a first driving motor 322, which is embedded in the mounting frame 310 and is suitable for driving the first rotating shaft 321 to rotate under the drive of the control module, thereby driving the first heating plate 320 to deflect; a second driving motor 332, which is embedded in the mounting frame 310 and is suitable for driving the second rotating shaft 331 to rotate under the drive of the control module, thereby driving the second heating plate 330 to deflect.

[0033] In the first state, the control module controls the cleaning mechanism 300 to block the air outlet 100, that is, the control module controls the first rotating shaft 321 and the second rotating shaft 331 to rotate, so that the first heating plate 320 and the second heating plate 330 block the air outlet 100. In the first state, the state diagram of the first heating plate 320 and the second heating plate 330 is as follows: Figure 6 In this state, the fan 200 does not work.

[0034] In the second state, the control module controls the cleaning mechanism 300 to heat the air outlet 100, and then controls the cleaning mechanism 300 to open the air outlet 100, that is, the control module controls the first heating plate 320 and the second heating plate 330 to work, heat the air outlet 100, and after heating for a preset time, controls the second rotating shaft 331 to rotate, so that the second heating plate 330 rotates to open the air outlet 100. The state of the second heating plate 330 is as follows: Figure 7 As shown, the airflow direction of the two fans 200 when working is as follows Figure 7 As shown in F.

[0035] In a preferred embodiment, in the third working state, the step of the control module detecting the air volume of the two fans 200 through the cleaning mechanism 300 includes: S1: controlling the first heating plate 320 and the second heating plate 330 to block the air outlet pipe 100 .

[0036] Specifically, the state diagram of the first heating plate 320 and the second heating plate 330 is as follows: Figure 6 shown.

[0037] S2: Control the two fans 200 to work alternately at the same power.

[0038] Specifically, one of the fans 200 is controlled to operate first, and then the other fan 200 is controlled to operate at the same power, so as to facilitate subsequent detection.

[0039] S3: Detect the reaction torques of the first driving motor 322 and the second driving motor 332, and determine whether the two reaction torques are consistent with corresponding preset values.

[0040] Specifically, since the airflow generated by the fan 200 blows directly toward the first heating plate 320 and the second heating plate 330, the rotation of the first heating plate 320 and the second heating plate 330 is suppressed through the first drive motor 322 and the second drive motor 332, and the reverse torque of the first drive motor 322 and the second motor is detected at this time to feedback the size of the wind force received by the first heating plate 320 and the second heating plate 330, thereby indirectly feeding back the air output of the two fans 200.

[0041] The preset value is the counter torque of the first driving motor 322 and the second driving motor 332 detected when there is no dirt on the two fans 200.

[0042] It should be noted that in order to reduce the starting frequency of the fan 200, in other embodiments, it can be determined whether the difference between the reverse torque and the corresponding preset value is within a preset range. If it is within the preset range, it means that the reverse torque is consistent with the corresponding preset value; if it is not within the range, it means that the reverse torque is inconsistent with the corresponding preset value.

[0043] S4: If they are consistent, it means that the air output of the two fans 200 is consistent with the preset air output. If they are inconsistent, the two fans 200 are controlled to operate at different powers, and the dirt on the fans 200 is cleaned by the airflow of the fans 200.

[0044] Specifically, the step of controlling the two fans 200 to enter the self-cleaning module in step S4 is: controlling the first heating plate 320 and the second heating plate 330 to block the air outlet 100; controlling the two fans 200 to operate at the first power and the second power at the same time, wherein the first power is greater than the second power, at this time, the cleaning of the fan 200 operating at the second power is completed; exchanging the power of the two fans 200 to complete the cleaning of the other fan 200. Specifically, the airflow generated by the two fans collides near the blades of the fan running at low power, generating violent turbulence, which can better clean the blades of the fan 200, thereby realizing the self-cleaning of the fan 200 and reducing the frequency and cost of manual cleaning. When the upper fan runs at the first power and the lower fan runs at the second power, the airflow in the air outlet 100 flows in the following direction: Figure 6 As shown by arrow F in the middle.

[0045] See also Figure 1 and Figure 3 In some embodiments, the air outlet duct 100 includes: a first tube body 110 and a second tube body 120; the second tube body 120 is inserted into the first tube body 110, and a rotating space 130 suitable for installing the installation frame 310 is reserved at the joint of the first tube body 110 and the second tube body 120; the installation frame 310 is circular, and the outer side wall of the installation frame 310 is provided with an annular rack 311 meshing with the rotating teeth 341 of the rotating motor 340.

[0046] The working state also includes: In the fourth working state, after the fan 200 is started, the control module is further configured to control the first heating plate 320 and the second heating plate 330 to rotate along the wind direction. Figure 8 As shown, the wind direction is Figure 8 As shown in F, the rotating motor 340 drives the mounting frame 310 to rotate, thereby adjusting the wind direction of the fan 200. It should be noted that the mounting frame 310 rotates only in the fourth working state, and its rotation direction is as shown in FIG. Figure 8As shown in F1, it returns to its original position after the work is completed so as not to affect the remaining working states.

[0047] In the fifth working state, after the fan 200 is started, the control module is further configured to control the first heating plate 320 and the second heating plate 330 to rotate in the opposite direction of the wind direction. Fig. 9 As shown, the wind direction is Fig. 9 As shown in F, the first heating plate 320 and the second heating plate 330 are rotated to form a “>” shape to collect dirt. After collecting the dirt, the working state is switched to the second working state to blow the dirt out of the air outlet 100.

[0048] See also Figure 3 and Figure 5 In order to install the installation frame 310, a rotating ring 312 is extended axially outward from the installation frame 310, and a rotating groove 131 is provided at the matching position between the rotating space 130 of the air outlet duct 100 and the rotating ring 312, and the installation frame 310 is rotatably arranged in the rotating groove 131 through the rotating ring 312.

[0049] See also Figure 1 and Figure 3 In some embodiments, the intelligent cleaning device for the fan 200 further includes: a horizontal diverter plate 400; the horizontal diverter plate 400 is arranged in the air outlet pipe 100, and the two fans 200 are respectively arranged on the top surface and the bottom surface of the horizontal diverter plate 400; the horizontal diverter plate 400 is provided with a notch 410 suitable for the first heating plate 320 and the second heating plate 330 to pass through. By setting the horizontal diverter plate 400, the air outlet sides of the two fans 200 are separated, so as to avoid the airflows blown out by the two fans 200 from interfering at the near end of the fan 200, so as to make the convergence point of the two airflows away from the two fans 200, improve the uniformity of the air blowing, and at the same time, separate the air inlet sides of the two fans 200, so as to avoid the dirt after cleaning from following the airflow into the fan 200.

[0050] See also Fig.10 At least one embodiment further provides a cleaning method for the fan 200 using the intelligent cleaning device as described above, the method comprising: S110: receiving a working status instruction; S120: Control the cleaning mechanism 300 to work according to the working status instruction.

[0051] In the first working state, when the fan 200 is stopped, the control module controls the cleaning mechanism 300 to block the air outlet 100. When the fan 200 is stopped, the air outlet 100 is blocked by the cleaning mechanism 300, thereby preventing external impurities from entering the room along the air outlet 100.

[0052] In the second working state, in winter, when the machine needs to be turned on, the control module is configured to first control the cleaning mechanism 300 to heat the air outlet pipe 100, then control the cleaning mechanism 300 to open the air outlet pipe 100, and control the two fans 200 to start, and complete the cleaning of the dirt in the air outlet pipe 100 through the airflow of the fans 200. It should be noted that the starting power of the fan 200 is relatively low, and the dirt in the air outlet pipe 100 will not be blown away directly. When collecting the dirt flowing out of the air outlet pipe 100, a dirt flow channel or a dirt collection frame is set according to the use requirements. At the same time, after the air outlet pipe 100 is heated, the dirt can be softened, thereby improving the cleaning effect.

[0053] In the third working state, when the machine is stopped, the control module is configured to detect the air volume of the two fans 200 through the cleaning mechanism 300 according to the preset time interval. When the air volume of the two fans 200 is inconsistent with the preset air volume, the two fans 200 are controlled to operate at different powers, and the dirt on the fans 200 is cleaned by the airflow of the fans 200. By setting two fans 200 for ventilation and setting the cleaning mechanism 300 to detect the air volume of the two fans 200, when it is detected that the air volume of the two fans 200 is inconsistent with the preset air volume, the two fans 200 are controlled to operate at different powers, so that the two airflows collide near the blades of the fan running at low power, generating violent turbulence, and better cleaning the blades of the fans 200, thereby realizing self-cleaning of the fans 200 and reducing the frequency and cost of manual cleaning.

[0054] In summary, the present invention provides an intelligent cleaning device and a cleaning method for a fan 200, wherein the intelligent cleaning device for the fan 200 comprises: an air outlet duct 100; two stacked fans 200, which are arranged in the air outlet duct 100; a cleaning mechanism 300, which is arranged in the air outlet duct 100 and is located at the air outlet side of the two fans 200; a control module, which is electrically connected to the cleaning mechanism 300 and is configured to control the cleaning mechanism 300 to work according to a working state; the working state comprises: a first working state, when the fan is stopped, the control module controls the cleaning mechanism 300 to block the air outlet duct 100; a second working state, in winter, When it is necessary to start the machine, the control module is configured to first control the cleaning mechanism 300 to heat the air outlet duct 100, then control the cleaning mechanism 300 to open the air outlet duct 100, and control the two fans 200 to start, and complete the cleaning of the dirt in the air outlet duct 100 through the airflow of the fans 200; in the third working state, when the machine is stopped, according to the preset time interval, the control module is configured to detect the air volume of the two fans 200 through the cleaning mechanism 300, and when the air volume of the two fans 200 is inconsistent with the preset air volume, control the two fans 200 to operate at different powers, and clean the dirt on the fans 200 through the airflow of the fans 200. Two fans 200 are set for ventilation, and a cleaning mechanism 300 is set to detect the air output of the two fans 200. When it is detected that the air output of the two fans 200 is inconsistent with the preset air output, the two fans 200 are controlled to operate at different powers, so that the two airflows collide in the fan 200 running at low power, generating violent turbulence, which can better clean the blades of the fan 200, thereby realizing self-cleaning of the fan 200 and reducing the frequency and cost of manual cleaning.
