Description

Technical Field

[0001] The present invention belongs to the field of cleaning technology, and particularly relates to a device for cleaning by means of the air flow of a fan, and more particularly to an intelligent cleaning device and a cleaning method for a fan. Background Art

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

[0003] In the related art, due to the relatively high density of animal breeding and the relatively low requirement for air quality, 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 screen is not provided at the air inlet of the fan, so as to ensure that the air output of the fan can meet the ventilation requirements. After long-term use, a large amount of dust and dirt will accumulate on the fan blades, thereby changing the areas of the air inlet and the air outlet of the fan, affecting the wind speed and wind pressure, and resulting in a reduction in the air output of the fan. It is necessary to regularly remove the fan manually for cleaning.

[0004] Therefore, how to clean the fan without removing it is a technical problem to be solved urgently at present.

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

Specific embodiments

[0067] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0068] In this document, when it is mentioned that the first component is located on the second component, this may mean that the first component can be directly formed on the second component, or a third component can be inserted between the first component and the second component.

[0069] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. In addition, in the drawings, to effectively describe the technical content, the thickness of the components may be exaggerated or reduced.

[0070] The following will, with reference to the accompanying drawings, elaborate on some embodiments of the present invention. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0071] Please refer to Figure 1 and Figure 2 , at least one embodiment provides an intelligent cleaning device for a fan 200, including: an air outlet pipe 100; two fans 200 stacked and arranged inside the air outlet pipe 100; a cleaning mechanism 300 arranged inside the air outlet pipe 100 and located on the air outlet side of the two fans 200; a control module electrically connected to the cleaning mechanism 300 and configured to control the cleaning mechanism 300 to operate according to the working state.

[0072] Specifically, the working state includes:

[0073] First working state: When the machine is shut down, the control module controls the cleaning mechanism 300 to block the air outlet pipe 100. When the fan 200 is shut down, the air outlet pipe 100 is blocked by the cleaning mechanism 300, thereby preventing external impurities from entering the room along the air outlet pipe 100.

[0074] Second working state: In winter, when the machine needs to be started, 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. The dirt in the air outlet pipe 100 is cleaned by the airflow of the fans 200. It should be noted that the starting power of the fans 200 is relatively low and will not directly blow away the dirt in the air outlet pipe 100. When collecting the dirt flowing out of the air outlet pipe 100, a dirt flow channel or a dirt collection box, etc. can be set according to the usage requirements. At the same time, after heating the air outlet pipe 100, the dirt can be softened, thereby improving the cleaning effect.

[0075] Third working state: When the machine is shut down, at preset time intervals, the control module is configured to detect the air volume output of the two fans 200 through the cleaning mechanism 300. When the air volume output of the two fans 200 is inconsistent with the preset air volume, the control module controls the two fans 200 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 output of the two fans 200, when it is detected that the air volume output 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 operating at low power, generating intense turbulence, which can better clean the blades of the fans 200, thereby realizing the self-cleaning of the fans 200 and reducing the frequency and cost of manual cleaning.

[0076] It should be noted that Figure 1 The direction of arrow F is the air outlet direction of the two fans.

[0077] Please refer to 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 pipe 100; a first heating plate 320 and a second heating plate 330, 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 rotationally connected to the mounting frame 310 through a first rotating shaft 321, and the top of the second heating plate 330 is rotationally 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 adapted to drive 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 adapted to drive the second rotating shaft 331 to rotate under the drive of the control module, thereby driving the second heating plate 330 to deflect.

[0078] In the first state, the control module controls the cleaning mechanism 300 to block the air outlet pipe 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 pipe 100. In the first state, a schematic diagram of the states of the first heating plate 320 and the second heating plate 330 is as Figure 6 shown. In this state, the fan 200 does not work.

[0079] In the second state, the control module controls the cleaning mechanism 300 to heat the air outlet pipe 100, and then controls the cleaning mechanism 300 to open the air outlet pipe 100, that is, the control module controls the first heating plate 320 and the second heating plate 330 to work, heat the air outlet pipe 100, and after heating for a preset time, control the second rotating shaft 331 to rotate to make the second heating plate 330 rotate to open the air outlet pipe 100. The state of the second heating plate 330 is as Figure 7 shown, and the air flow direction when the two fans 200 work is as Figure 7 shown by F in.

[0080] In a preferred embodiment, in the third working state, the steps for the control module to detect the air output of the two fans 200 through the cleaning mechanism 300 include:

[0081] S1: Control the first heating plate 320 and the second heating plate 330 to block the air outlet pipe 100.

[0082] Specifically, a schematic diagram of the states of the first heating plate 320 and the second heating plate 330 is as Figure 6 shown.

[0083] S2: Control the two blowers 200 to work alternately at the same power.

[0084] Specifically, first control one of the blowers 200 to work, and then control the other blower 200 at the same power, so as to facilitate subsequent detection.

[0085] S3: Detect the reaction torques of the first drive motor 322 and the second drive motor 332, and determine whether the two reaction torques are consistent with the corresponding preset values.

[0086] Specifically, since the airflow generated by the blower 200 directly blows on the first heating plate 320 and the second heating plate 330, through the first drive motor 322 and the second drive motor 332, the rotation of the first heating plate 320 and the second heating plate 330 is inhibited, and the reaction torques of the first drive motor 322 and the second motor at this time are detected to feedback the wind force received by the first heating plate 320 and the second heating plate 330, so as to indirectly feedback the air volume output by the two blowers 200.

[0087] Among them, the preset values are the reaction torques of the first drive motor 322 and the second drive motor 332 detected when there is no dirt on the two blowers 200.

[0088] It should be noted that in order to reduce the startup frequency of the blower 200, in other embodiments, it can be determined whether the difference between the reaction torque and the corresponding preset value is within a preset range. If it is within the preset range, it means that the reaction torque is consistent with the corresponding preset value; if it is not within the range, it means that the reaction torque is inconsistent with the corresponding preset value.

[0089] S4: If they are consistent, it means that the air volume output by the two blowers 200 is consistent with the preset air volume; if they are inconsistent, control the two blowers 200 to operate at different powers, and use the airflow of the blowers 200 to clean the dirt on the blowers 200.

[0090] Specifically, the steps of controlling the two blowers 200 to enter the self-cleaning module in step S4 are as follows: control the first heating plate 320 and the second heating plate 330 to block the air outlet pipe 100; at the same time, control the two blowers 200 to operate at the first power and the second power, where the first power is greater than the second power. At this time, the cleaning of the blower 200 operating at the second power is completed; exchange the powers of the two blowers 200 to complete the cleaning of the other blower 200. Specifically, the airflow generated by the two blowers collides near the blades of the blower operating at low power, generating intense turbulence, which can better clean the blades of the blower 200, thus realizing the self-cleaning of the blower 200 and reducing the frequency and cost of manual cleaning. When the upper blower operates at the first power and the lower blower operates at the second power, the airflow direction in the air outlet pipe 100 is as Figure 6as shown by arrow F in the figure.

[0091] Please refer to Figure 1 and Figure 3 In some embodiments, the air outlet pipe 100 includes: a first pipe body 110 and a second pipe body 120; the second pipe body 120 is inserted into the first pipe body 110, and a rotation space 130 suitable for installing the installation frame 310 is reserved at the insertion joint of the first pipe body 110 and the second pipe body 120; the installation frame 310 is circular, and an annular rack 311 engaged with the rotation teeth 341 of the rotation motor 340 is arranged on the outer side wall of the installation frame 310.

[0092] The working state further includes:

[0093] A 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 air outlet direction, as Figure 8 shown, the air outlet direction is as Figure 8 shown by F in the figure, and drive the rotation motor 340 to drive the installation frame 310 to rotate, so as to adjust the air direction of the fan 200. It should be noted that the installation frame 310 only rotates in the fourth working state, and its rotation direction is as Figure 8 shown by F1 in the figure, and returns to its original position after the work is completed, so as not to affect the remaining working states.

[0094] A 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 reverse direction of the air outlet direction, as Figure 9 shown, the air outlet direction is as Figure 9 shown by F in the figure, so that the first heating plate 320 and the second heating plate 330 rotate to form a ">" shape to collect dirt. After collecting the dirt, switch the working state to the second working state to blow the dirt out of the air outlet pipe 100.

[0095] Please refer to Figure 3 and Figure 5 For installing the installation frame 310, the installation frame 310 axially extends out a rotating ring 312, a rotating groove 131 is opened at the matching position of the rotation space 130 of the air outlet pipe 100 and the rotating ring 312, and the installation frame 310 is rotatably arranged in the rotating groove 131 through the rotating ring 312.

[0096] Please refer to Figure 1 and Figure 3, in some embodiments, the intelligent cleaning device for the fan 200 further includes: a horizontal flow splitter 400; the horizontal flow splitter 400 is disposed in the air outlet pipe 100, and the two fans 200 are respectively disposed on the top surface and the bottom surface of the horizontal flow splitter 400; the horizontal flow splitter 400 is provided with a notch 410 adapted to allow the first heating plate 320 and the second heating plate 330 to pass through. By providing the horizontal flow splitter 400, the air outlet sides of the two fans 200 are separated, thereby preventing the air flows blown by the two fans 200 from interfering at the proximal end of the fans 200, moving the convergence point of the two air flows away from the two fans 200, improving the uniformity of the air blowing. At the same time, the air inlet sides of the two fans 200 are separated, thereby preventing the dirt after cleaning from following the air flow and entering the fans 200.

[0097] Please refer to Figure 10 , at least one embodiment further provides a cleaning method for the intelligent cleaning device for the fan 200 as described above, the method comprising:

[0098] S110: Receive a working state instruction;

[0099] S120: Control the cleaning mechanism 300 to work according to the working state instruction.

[0100] Among them, in the first working state, when the machine is stopped, the control module controls the cleaning mechanism 300 to block the air outlet pipe 100. When the fan 200 is stopped, the air outlet pipe 100 is blocked by the cleaning mechanism 300, thereby preventing external impurities from entering the room along the air outlet pipe 100.

[0101] In the second working state, in winter when the machine needs to be started, 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 clean the dirt in the air outlet pipe 100 through the air flow of the fans 200. It should be noted that the starting power of the fan 200 is relatively low and will not directly blow the dirt in the air outlet pipe 100 away. When collecting the dirt flowing out of the air outlet pipe 100, a dirt flow channel or a dirt collection frame, etc. can be set according to the usage requirements. At the same time, after heating the air outlet pipe 100, the dirt can be softened, thereby improving the cleaning effect.

[0102] Third working state: When the machine is stopped, at preset time intervals, the control module is configured to detect the air output of the two fans 200 through the cleaning mechanism 300. When 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, and the dirt on the fans 200 is cleaned by the airflow of the fans 200. By arranging two fans 200 for ventilation and arranging a cleaning mechanism 300 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 near the blades of the fan operating at low power, generating intense turbulence, which can better clean the blades of the fan 200, thus realizing self-cleaning of the fan 200 and reducing the frequency and cost of manual cleaning.

[0103] In summary, the present invention provides an intelligent cleaning device and cleaning method for a fan 200. The intelligent cleaning device for a fan 200 includes: an air outlet pipe 100; two fans 200 arranged in a stacked manner, which are arranged in the air outlet pipe 100; a cleaning mechanism 300, which is arranged in the air outlet pipe 100 and 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 cleaning mechanism 300 to work according to the working state; the working state includes: a first working state, when the machine is stopped, the control module controls the cleaning mechanism 300 to block the air outlet pipe 100; a second working state, in winter when starting the machine is required, 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 clean the dirt in the air outlet pipe 100 through the airflow of the fans 200; a third working state, when the machine is stopped, at preset time intervals, the control module is configured to detect the air output of the two fans 200 through the cleaning mechanism 300. When 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, and the dirt on the fans 200 is cleaned by the airflow of the fans 200. By arranging two fans 200 for ventilation and arranging a cleaning mechanism 300 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 operating at low power, generating intense turbulence, which can better clean the blades of the fan 200, thus realizing self-cleaning of the fan 200 and reducing the frequency and cost of manual cleaning.
