Description

Technical Field

[0001] This invention relates to the field of kitchen equipment technology, and in particular to an adaptive cleaning fan, a range hood, and an adaptive control method. Background Technology

[0002] Currently, in order to achieve the self-cleaning function of range hoods, cleaning methods such as water jet spraying, steam spraying, and drum washing are commonly used. Among them, the drum washing self-cleaning solution refers to using a water pump to draw water from the water supply box into the inner cavity of the volute and accumulate it at the bottom of the volute. After the cleaning liquid covers part of the blades at the bottom of the impeller, the blades are cleaned in the cleaning liquid by rotating the impeller, thereby achieving the self-cleaning of the impeller.

[0003] However, the self-cleaning functions of existing range hoods on the market generally have the following shortcomings: 1) They cannot adaptively select the amount of cleaning liquid to clean based on the amount of grease on the impeller, and only use a fixed amount of cleaning liquid. This can easily lead to water waste and energy loss in the case of light grease, and insufficient water in the case of heavy grease, which may not guarantee the cleaning effect; 2) The "drum wash" self-cleaning scheme in which the impeller rotates in the cleaning liquid lacks a reliable water supply box water volume detection device and method. There is a risk that if the user does not add enough water, the cleaning liquid accumulated in the volute will not be able to cover the bottom blades of the impeller, resulting in inadequate cleaning or even failure of the drum wash self-cleaning. Summary of the Invention

[0004] Therefore, in order to address the problems of water wastage or inadequate cleaning in drum-type self-cleaning range hoods, this invention provides an adaptive cleaning fan, a range hood, and an adaptive control method.

[0005] In one embodiment of this application, the present invention provides an adaptive cleaning fan, comprising:

[0006] Control device;

[0007] The fan body includes a volute and an impeller rotatably disposed within the volute;

[0008] A liquid supply device, which is connected to the volute, and a control device communicatively connected to the liquid supply device, wherein the control device is used to control the liquid supply device to initially supply a predetermined amount of cleaning liquid to the volute after the self-cleaning function is activated, so that it accumulates at the bottom of the volute; and

[0009] A measuring device is disposed in the volute, and a control device is communicatively connected to the measuring device. The control device is used to control the measuring device to measure the liquid level inside the volute after the initial supply of cleaning fluid, so as to calculate the total amount of oil on the impeller.

[0010] The control device is communicatively connected to the main body of the fan. The control device is used to determine the total amount of cleaning fluid required based on the calculated total amount of oil stains, so as to control the liquid supply device to supply an adaptive amount of cleaning fluid to the volute again, and after the cleaning fluid is supplied again, control the impeller to rotate for drum washing.

[0011] In one embodiment of this application, the measuring device is a distance sensor, which is disposed on the top of the volute and used to measure the distance between itself and the bottom liquid surface of the volute to obtain the liquid level height inside the volute.

[0012] In one embodiment of this application, the measuring device measures the liquid level height h1 when the predetermined amount of cleaning fluid is added to the volute and the total amount of oil on the impeller in the current state. 总 The following relationship is satisfied between them:

[0013] and

[0014] Where: W1 is the amount of oil adhering to the blades of the impeller submerged in the cleaning fluid in the current state; h0 is the liquid level height measured by the measuring device when the predetermined amount of cleaning fluid is added to the volute in the initial state; S(h) is the liquid surface area of ​​the cleaning fluid inside the volute at the liquid level height h; n0 is the total number of blades of the impeller; n1 is the number of blades of the impeller submerged in the cleaning fluid when the predetermined amount of cleaning fluid is added to the volute in the initial state.

[0015] In one embodiment of this application, the control device includes a receiving module, a processing module, a grading module, and a control module that are communicatively connected to each other. The receiving module is communicatively connected to the measuring device and is used to receive liquid level data measured by the measuring device in the current state. The processing module is used to process the liquid level data to obtain the total amount of oil contamination on the impeller in the current state. The grading module is used to determine the oil contamination level of the impeller based on the total amount of oil contamination on the impeller, so as to obtain the required total amount of cleaning fluid corresponding to the oil contamination level. The control module is communicatively connected to the liquid supply device and the blower body, and is used to first control the liquid supply device to replenish the cleaning fluid to the volute to the required total amount of cleaning fluid corresponding to the oil contamination level, and then control the impeller to rotate to start cleaning.

[0016] In one embodiment of this application, the grading module is further used to compare the total amount of oil on the impeller with a preset grade threshold to classify the oil level of the impeller into four grades: extremely light oil, light oil, medium oil, and heavy oil.

[0017] In one embodiment of this application, the grading module is configured to: determine that the impeller is in an extremely light oil stain level in response to the total amount of oil stain on the impeller being greater than or equal to zero and less than a first oil stain threshold, so as to obtain a total amount of first cleaning fluid equal to the predetermined amount; determine that the impeller is in a light oil stain level in response to the total amount of oil stain on the impeller being greater than or equal to the first oil stain threshold and less than a second oil stain threshold, so as to obtain a total amount of second cleaning fluid greater than the predetermined amount; determine that the impeller is in a medium oil stain level in response to the total amount of oil stain on the impeller being greater than or equal to the second oil stain threshold and less than a third oil stain threshold, so as to obtain a total amount of third cleaning fluid greater than the total amount of second cleaning fluid; and determine that the impeller is in a heavy oil stain level in response to the total amount of oil stain on the impeller being greater than or equal to the third oil stain threshold, so as to obtain a total amount of fourth cleaning fluid greater than the total amount of third cleaning fluid.

[0018] In one embodiment of this application, the liquid supply device includes a liquid supply box, a liquid pump, and a liquid extraction pipe. The liquid extraction pipe is sequentially connected to the liquid supply box, the liquid pump, and the volute. The liquid pump is communicatively connected to the control device and is used to extract cleaning liquid from the liquid supply box under the control of the control device and deliver it to the volute through the liquid extraction pipe.

[0019] In one embodiment of this application, the liquid supply device further includes a liquid level detector disposed in the liquid supply box, and the control device is communicatively connected to the liquid level detector for controlling the liquid level detector to detect the current liquid level in the liquid supply box in order to determine whether the current liquid level meets the cleaning requirements.

[0020] In one embodiment of this application, the control device further includes a comparison module and a prompting module that are communicatively connected to each other. The comparison module is communicatively connected to the liquid level detector and the control module. The comparison module is used to compare the current liquid level with a predetermined amount before entering the oil stain detection stage. When the current liquid level is greater than or equal to the predetermined amount, the comparison module sends an oil stain detection signal to the control module, and when the current liquid level is less than the predetermined amount, the comparison module sends a replenishment signal to the prompting module. When the control module receives the oil stain detection signal, it controls the liquid supply device to initially supply the predetermined amount of cleaning fluid to the volute to enter the oil stain detection stage. The prompting module is used to issue a replenishment prompt when the replenishment signal is received.

[0021] In one embodiment of this application, the comparison module is further configured to compare the current liquid level with the total amount of cleaning fluid required corresponding to the oil stain level after entering the oil stain detection stage, so as to send a cleaning signal to the control module when the current liquid level is greater than or equal to the total amount of cleaning fluid required, and send a replenishment signal to the prompt module when the current liquid level is less than the total amount of cleaning fluid required; the control module is configured to control the liquid supply device to supply cleaning fluid to the volute again to the total amount of cleaning fluid required to start cleaning when receiving the cleaning signal.

[0022] According to another aspect of this application, this application further provides a range hood, comprising:

[0023] shell; and

[0024] The adaptive cleaning fan described above is assembled into the housing.

[0025] According to another aspect of this application, this application further provides an adaptive cleaning method, comprising the steps of:

[0026] After the self-cleaning function is activated, the liquid supply device is controlled to initially supply a predetermined amount of cleaning liquid to the volute, so that it can accumulate at the bottom of the volute.

[0027] After the initial supply of cleaning fluid, the control and measuring device measures the liquid level inside the volute to calculate the total amount of oil on the impeller.

[0028] Based on the calculated total amount of oil contamination, the required total amount of cleaning fluid is determined to control the fluid supply device to resupply an appropriate amount of cleaning fluid to the volute; and

[0029] After the cleaning fluid is supplied again, the impeller is controlled to rotate for drum washing.

[0030] In one embodiment of this application, in the step of controlling the measuring device to measure the liquid level inside the volute after the initial supply of cleaning fluid in order to calculate the total amount of oil on the impeller:

[0031] The measuring device measures the liquid level height h1 when the predetermined amount of cleaning fluid is added to the volute and the total amount of oil on the impeller in the current state. 总 The following relationship is satisfied between them:

[0032] and

[0033] Where: W1 is the amount of oil adhering to the blades of the impeller submerged in the cleaning fluid in the current state; h0 is the liquid level height when the predetermined amount of cleaning fluid is added to the volute in the initial state; S(h) is the liquid surface area of ​​the cleaning fluid inside the volute at the liquid level height h; n0 is the total number of blades of the impeller; n1 is the number of blades of the impeller submerged in the cleaning fluid when the predetermined amount of cleaning fluid is added to the volute in the initial state.

[0034] In one embodiment of this application, the step of determining the required total amount of cleaning fluid based on the calculated total amount of oil stains, so as to control the fluid supply device to supply an adaptive amount of cleaning fluid to the volute again, includes the following steps:

[0035] Based on the total amount of oil contamination on the impeller, the oil contamination level of the impeller is determined to obtain the required total amount of cleaning fluid corresponding to that oil contamination level; and

[0036] Control the liquid supply device to replenish the volute with cleaning fluid to the total amount required for the level of oil contamination.

[0037] In one embodiment of this application, the step of determining the oil contamination level of the impeller based on the total amount of oil contamination, in order to obtain the required total amount of cleaning fluid corresponding to the oil contamination level, includes the following steps:

[0038] Compare the total amount of oil on the impeller with the preset threshold level.

[0039] In response to the impeller having a total oil stain count greater than or equal to zero and less than a first oil stain threshold, the impeller is determined to be in an extremely light oil stain level in order to obtain a total amount of first cleaning fluid equal to the predetermined amount.

[0040] In response to the impeller having a total amount of oil contamination greater than or equal to the first oil contamination threshold and less than the second oil contamination threshold, the impeller is determined to be in a light oil contamination level, so as to obtain a total amount of second cleaning fluid greater than the predetermined amount.

[0041] In response to the impeller's total oil contamination being greater than or equal to the second oil contamination threshold and less than the third oil contamination threshold, the impeller is determined to be at a medium oil contamination level, so as to obtain a third cleaning fluid quantity greater than the second required quantity; and

[0042] In response to the impeller having a total amount of oil contamination greater than or equal to the third oil contamination threshold, the impeller is determined to be in a heavy oil contamination level, so as to obtain a fourth cleaning fluid total amount greater than the third cleaning fluid total amount required.

[0043] In one embodiment of this application, the adaptive cleaning method further includes the step of:

[0044] The liquid level detector controls the current liquid level in the liquid supply box of the liquid supply device to determine whether the current liquid level meets the cleaning requirements.

[0045] In one embodiment of this application, the step of controlling the liquid level detector to detect the current liquid level in the liquid supply box of the liquid supply device to determine whether the current liquid level meets the cleaning requirements includes the following steps:

[0046] Before proceeding to the oil spill detection stage, compare the current liquid volume with the predetermined volume.

[0047] In response to the current liquid level being greater than or equal to the predetermined amount, an oil stain detection signal is sent to control the liquid supply device to initially supply the predetermined amount of cleaning fluid to the volute, thus initiating the oil stain detection phase; and

[0048] In response to the current liquid level being less than the predetermined amount, a liquid replenishment signal is sent to issue a liquid replenishment prompt.

[0049] In one embodiment of this application, the step of controlling the liquid level detector to detect the current liquid level in the liquid supply box of the liquid supply device to determine whether the current liquid level meets the cleaning requirements further includes the following steps:

[0050] After entering the oil stain detection stage, compare the current liquid volume with the total amount of cleaning fluid required corresponding to the oil stain level;

[0051] In response to the current liquid level being greater than or equal to the required total amount of cleaning fluid, a cleaning signal is sent to control the liquid supply device to resupply cleaning fluid to the volute to the required total amount of cleaning fluid, thus initiating the cleaning phase; and

[0052] In response to the current liquid level being less than the total amount of cleaning fluid required, a replenishment signal is sent to issue a replenishment prompt.

[0053] In one embodiment of this application, the step of controlling the liquid level detector to detect the current liquid level in the liquid supply box of the liquid supply device to determine whether the current liquid level meets the cleaning requirements further includes the following steps:

[0054] After the cleaning fluid is replenished, the amount of cleaning fluid stored in the supply box is further detected by the liquid level detector to compare the amount of cleaning fluid stored with the amount of cleaning fluid to be replenished.

[0055] In response to the stored cleaning fluid volume being greater than or equal to the required replenishment volume, the system enters either the oil stain detection stage or the cleaning stage; and

[0056] If the stored cleaning fluid volume is less than the required replenishment volume, a prompt will be made to continue replenishing the cleaning fluid to the supply box.

[0057] In summary, the adaptive cleaning fan of this application is a drum washing self-cleaning fan with adaptive characteristics. It can extract a corresponding amount of cleaning fluid for cleaning based on the current amount of oil on the volute and impeller, thereby achieving energy and water conservation while ensuring cleaning effectiveness. Simultaneously, the adaptive cleaning method of this application first injects a predetermined amount of cleaning fluid into the volute until it covers a portion of the impeller blades at the bottom. Then, a distance sensor measures the distance between the liquid level at the bottom of the volute and the liquid level at the bottom, comparing this distance with the initial liquid level height to easily calculate the total amount of oil adhering to all the impeller blades. This method is simple and easy to implement.

[0058] Furthermore, the adaptive cleaning method of this application can also measure the distance between the liquid level at the bottom of the liquid supply box and the distance sensor, and calculate the current liquid level of the liquid supply box. If the current liquid level is less than the minimum liquid level for drum washing or the amount of cleaning liquid to be added, it indicates that the liquid level in the liquid supply box is insufficient, and a liquid replenishment prompt is issued to remind the user that cleaning liquid needs to be added; otherwise, it indicates that the liquid level in the liquid supply box is sufficient, and self-cleaning continues to be performed to prevent drum washing cleaning failure due to insufficient liquid level.

[0072] The above description of the main component symbols, together with the accompanying drawings and specific embodiments, provides a more detailed explanation of the present invention. Detailed Implementation

[0073] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0074] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation shown in the accompanying drawings.

[0075] The positional relationships are provided only for the convenience of describing the invention and for simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0076] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0077] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0078] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0079] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0080] Considering that existing technologies address varying levels of oil contamination on impellers, using only a fixed amount of cleaning fluid can easily lead to insufficient cleaning or excessive waste. Therefore, this application provides an adaptive cleaning fan, range hood, and method that can adaptively adjust the cleaning fluid volume based on the oil contamination level of the impeller, achieving energy and water conservation while ensuring effective cleaning.

[0081] Specifically, refer to Figures 1 to 3As shown, one embodiment of this application provides a range hood, which may include a housing 2 and an adaptive cleaning fan 1 mounted on the housing 2 for absorbing cooking fumes. It is understood that the range hood of this application may also include, but is not limited to, components such as an oil sludge box or oil cup to assist in completing the functions of fume extraction and self-cleaning; these will not be elaborated upon here.

[0082] More specifically, such as Figures 2 to 8 As shown, the adaptive cleaning fan 1 may include a fan body 10, a liquid supply device 20, a measuring device 30, and a control device 40. The fan body 10 includes a volute 11 and an impeller 12 rotatably disposed within the volute 11. The liquid supply device 20 is connected to the volute 11, and the control device 40 is communicatively connected to the liquid supply device 20. After the self-cleaning function is activated, the control device 40 controls the liquid supply device 20 to initially supply a predetermined amount of cleaning fluid to the volute 11 for accumulation at the bottom of the volute 11. The measuring device 30 is disposed within the volute 11, and the control device 40 is communicatively connected to the measuring device 30. After the initial supply of cleaning fluid, the control device 40 controls the measuring device 30 to measure the liquid level height within the volute 11 to calculate the total amount of oil contamination on the impeller. The control device 40 is communicatively connected to the blower body 10. The control device 40 determines the required total amount of cleaning fluid based on the calculated total amount of oil, controls the fluid supply device 20 to resupply an adaptive amount of cleaning fluid to the volute, and controls the impeller 12 to rotate for drum washing after the cleaning fluid is resupply. It is understood that the cleaning fluid mentioned in this application may be, but is not limited to, water or other liquids with added detergent; further details are omitted here. Furthermore, the adaptive amount mentioned in this application refers to the difference between the total amount of cleaning fluid and the predetermined amount.

[0083] It is worth noting that, such as Figure 4 As shown, the impeller 12 has multiple blades 120 arranged circumferentially and extending axially. When the impeller 12 rotates inside the volute 11, the gas inside the volute 11 is driven by the blades 120 to be discharged from the air outlet of the volute 11, creating a negative pressure in the central region of the volute 11. This negative pressure draws in external oil fumes through the air inlet of the volute 11, thus achieving the effect of oil fume extraction.

[0084] Specifically, since the oil adhesion on each blade 120 of the impeller 12 is almost identical when oil adheres to it, the adaptive cleaning fan 1 of this application can obtain the total amount of oil adhered to the impeller 12 based on the amount of oil adhered to the blades 120 submerged in cleaning fluid. Furthermore, the adaptive cleaning fan 1 of this application can measure the liquid level inside the volute 11 after the initial supply of cleaning fluid using the measuring device 30. It first compares the liquid level with that of a clean impeller under the same liquid volume to calculate the amount of oil adhered to the blades submerged in a predetermined amount of cleaning fluid. Then, based on the proportion of the blades 120 in cleaning fluid to all blades 120 in the impeller 12, it calculates the total amount of oil adhered to the impeller 12 to determine the degree of oil contamination on the impeller 12. Based on the degree of oil contamination, it adaptively determines the required total amount of cleaning fluid and, after replenishing the corresponding amount of cleaning fluid, performs drum-type self-cleaning to achieve energy and water conservation while ensuring cleaning effectiveness.

[0085] For example, such as Figure 4 and Figure 5 As shown, the measuring device 30 can be implemented as, but is not limited to, a distance sensor 31. This distance sensor 31 is disposed at the top of the volute 11 and is used to measure the distance between itself and the bottom liquid surface of the volute 11 to obtain the liquid level height within the volute 11. In other words, the liquid level height mentioned in this application can refer to the distance between the surface of the cleaning fluid within the volute 11 and the distance sensor 31. It is understood that in other examples of this application, the liquid level height can also refer to the depth (liquid level) of the cleaning fluid within the volute 11, which can be obtained by subtracting the measured distance from the distance between the distance sensor 31 and the lowest position of the volute 11; or it can be obtained directly by other types of measuring devices such as a level gauge, which will not be elaborated upon in this application.

[0086] Optionally, such as Figure 5 As shown, the measuring device 30 measures the liquid level height h1 when a predetermined amount of cleaning fluid is added to the volute 11 and the total amount of oil on the impeller 12 in the current state. 总 The following relationship exists between them:

[0087] and

[0088] Where: W1 is the amount of oil adhering to the blades of the impeller 12 submerged in the cleaning fluid in the current state; h1 is the liquid level height measured by the measuring device 30 when a predetermined amount of cleaning fluid is added to the volute 11 in the current state; h0 is the liquid level height measured by the measuring device 30 when a predetermined amount of cleaning fluid is added to the volute 11 in the initial state; S(h) is the liquid surface area of ​​the cleaning fluid inside the volute 11 at liquid level h; W 总n0 represents the total amount of oil on the impeller 12 in its current state; n0 represents the total number of blades on the impeller 12; n1 represents the number of blades submerged in the cleaning fluid when a predetermined amount of cleaning fluid is added to the volute 11 in the initial state. It is understood that the initial state mentioned in this application can refer to the state of the fan body 10 when it leaves the factory, i.e., both the volute 11 and the impeller 12 are free of oil and are in a clean state; the current state mentioned in this application refers to the state of the fan body 10 when the self-cleaning function is activated, i.e., both the volute 11 and the impeller 12 are covered with oil and are in an oily state.

[0089] It is worth noting that the liquid surface area S(h) mentioned in this application is determined by the geometric dimensions of the volute 11 and the impeller 12, and can be integrated into the range hood system. The predetermined amount mentioned in this application can be, but is not limited to, the minimum liquid volume required for the self-cleaning of the adaptive cleaning fan 1, and is also determined by the geometric dimensions of the volute 11 and the impeller 12. As long as it can be ensured that after adding the predetermined amount of cleaning liquid to the volute 11, some blades in the impeller 12 are submerged in the cleaning liquid, this application will not elaborate further. It is understood that once the predetermined amount is determined, the initial liquid level height h0 and the number of blades submerged in the cleaning liquid n1 are also determined by the geometric dimensions of the volute 11 and the impeller 12, and can be obtained / measured through factory testing of the range hood and integrated into the range hood system.

[0090] In addition, the bottom of the volute 11 is usually provided with an oil leakage hole. In order to prevent the cleaning fluid injected during self-cleaning from flowing out of the oil leakage hole, the oil leakage hole must be closed first when the self-cleaning function is started, and then the predetermined amount of cleaning fluid is supplied to the volute 11 for the first time through the liquid supply device 20.

[0091] According to the above embodiments of this application, as Figure 2 As shown, the control device 40 may include a receiving module 41, a processing module 42, a grading module 43, and a control module 44 that are communicatively connected to each other. The receiving module 41 is communicatively connected to the measuring device 30 and is used to receive liquid level data measured by the measuring device 30 in the current state. The processing module 42 is used to process the liquid level data to obtain the total amount of oil on the impeller 12 in the current state. The grading module 43 is used to determine the oil level of the impeller 12 based on the total amount of oil on the impeller 12, so as to obtain the required total amount of cleaning fluid. The control module 44 is communicatively connected to the liquid supply device 20 and the blower body 10, and is used to first control the liquid supply device 20 to replenish the cleaning fluid to the volute 11 to the required total amount of cleaning fluid, and then control the impeller 12 to rotate to start cleaning.

[0092] Optionally, the grading module 43 of the control device 40 can compare the total amount of oil on the impeller 12 with a preset grade threshold to classify the oil level of the impeller 12 into four grades: very light oil, light oil, medium oil, and heavy oil. The total amount of cleaning fluid required for each grade is different and increases with the grade, so as to achieve water and energy saving while ensuring the cleaning effect.

[0093] For example, such as Figure 8 As shown, the grading module 43 is used in response to the total amount of oil W of the impeller 12. 总 Greater than or equal to zero and less than the first oil contamination threshold K1, i.e., 0 ≤ W 总 <K1, indicating that the impeller 12 is at an extremely light oil stain level, in order to obtain a total amount V1 of the first cleaning fluid required, equal to the predetermined amount. At this time, the amount of cleaning fluid to be replenished is 0, that is, the control module 44 can control the liquid supply device 20 to stop replenishing the cleaning fluid and control the impeller 12 to rotate to start cleaning directly.

[0094] The grading module 43 is used in response to the total amount of oil sludge W on the impeller 12. 总 The oil stain threshold is greater than or equal to the first oil stain threshold K1 and less than the second oil stain threshold K2, i.e., K1≤W 总 <K2, indicating that the impeller 12 is at a light oil stain level, in order to obtain a total amount V2 of the second cleaning fluid required, which is greater than the predetermined amount. At this time, the amount of cleaning fluid to be replenished is V2-V1, that is, the control module 44 can first control the liquid supply device 20 to replenish the cleaning fluid to the volute 11 to the total amount V2 required for the second cleaning fluid, and then control the impeller 12 to rotate to start cleaning.

[0095] The grading module 43 is used in response to the total amount of oil sludge W on the impeller 12. 总 The oil contamination threshold is greater than or equal to the second oil contamination threshold K2 and less than the third oil contamination threshold K3, i.e., K2 ≤ W. 总 <K3 indicates that the impeller 12 is at a medium oil contamination level, in order to obtain a third cleaning fluid volume V3 that is greater than the total volume V2 required for the second cleaning fluid. At this time, the amount of cleaning fluid to be replenished is V3-V1, that is, the control module 44 can first control the liquid supply device 20 to replenish the cleaning fluid to the volute 11 to the total volume V3 required for the third cleaning fluid, and then control the impeller 12 to rotate to start cleaning.

[0096] The grading module 43 is used in response to the total amount of oil sludge W on the impeller 12. 总 Greater than or equal to the third oil contamination threshold K3, i.e., W 总If K3 is greater than or equal to 3, the impeller 12 is determined to be at a heavy oil contamination level, so that a fourth cleaning fluid total volume V4, greater than the total volume V3 required for the third cleaning fluid, is obtained. At this time, the amount of cleaning fluid to be replenished is V4-V1, that is, the control module 44 can first control the liquid supply device 20 to replenish the cleaning fluid to the volute 11 to the total volume V4 required for the fourth cleaning fluid, and then control the impeller 12 to rotate to start cleaning.

[0097] In the above embodiments of this application, such as Figure 2 and Figure 6 As shown, the liquid supply device 20 may include a liquid supply box 21, a liquid pump 22, and a liquid extraction pipe 23. The liquid extraction pipe 23 is sequentially connected to the liquid supply box 21, the liquid pump 22, and the volute 11. The liquid pump 22 is communicatively connected to the control device 40 and is used to draw cleaning fluid from the liquid supply box 21 under the control of the control device 40 and deliver it to the volute 11 through the liquid extraction pipe 23. It is understood that the liquid supply box 21 may, but is not limited to, be installed in the housing 2, and the liquid pump 22 may, but is not limited to, be implemented as a submersible pump installed at the bottom of the liquid supply box 21. This application will not elaborate further on this.

[0098] It is worth noting that, due to the limited capacity of the liquid supply box 21, and the fact that the drum washer self-cleaning requires the cleaning fluid to submerge part of the blades, it is necessary to check whether the amount of cleaning fluid stored in the liquid supply box 21 is sufficient during self-cleaning to prevent self-cleaning failure due to insufficient cleaning fluid. Therefore, if... Figure 2 , Figure 6 as well as Figure 7 As shown, the liquid supply device 20 of this application may further include a liquid level detector 24 disposed in the liquid supply box 21. The control device 40 is communicatively connected to the liquid level detector 24 and is used to control the liquid level detector 24 to detect the current liquid level of the liquid supply box 21 in order to determine whether the current liquid level meets the cleaning requirements.

[0099] Optionally, such as Figure 7 As shown, the liquid level detector 24 can, but is not limited to, be implemented as a distance sensor. This distance sensor is positioned on top of the liquid supply box 21 to measure the distance between itself and the bottom liquid surface of the liquid supply box 21, thereby calculating the current liquid level in the liquid supply box 21. Accordingly, as... Figure 2As shown, the control device 40 may further include a comparison module 45 and a prompting module 46 communicatively connected to each other. The comparison module 45 is communicatively connected to the liquid level detector 24 and the control module 44, and is used to compare the current liquid level with a predetermined amount before entering the oil stain detection stage. When the current liquid level is greater than or equal to the predetermined amount, an oil stain detection signal is sent to the control module 44, and when the current liquid level is less than the predetermined amount, a replenishment signal is sent to the prompting module 46. The control module 44 is used to control the liquid supply device 20 to initially supply the predetermined amount of cleaning fluid to the volute 11 to enter the oil stain detection stage when it receives the oil stain detection signal. The prompting module 46 is used to issue a replenishment prompt when it receives the replenishment signal, so as to remind the user to replenish the cleaning fluid in the liquid supply box 21. It is understood that the adaptive cleaning fan 1 of this application may, but is not limited to, remind the user to replenish the cleaning fluid in the liquid storage box through panel lights.

[0100] Optionally, the comparison module 45 is further configured to compare the current liquid level with the total amount of cleaning fluid required corresponding to the oil stain level after entering the oil stain detection stage, so as to send a cleaning signal to the control module 44 when the current liquid level is greater than or equal to the total amount of cleaning fluid required, and send a replenishment signal to the prompt module 46 when the current liquid level is less than the total amount of cleaning fluid required; the control module 44 is configured to control the liquid supply device 20 to supply cleaning fluid to the volute 11 again to the total amount of cleaning fluid required to start cleaning when the cleaning signal is received; the prompt module 46 is configured to issue a replenishment prompt when the replenishment signal is received, so as to remind the user to replenish the cleaning fluid to the liquid supply box 21.

[0101] It is worth noting that after the user replenishes the cleaning fluid, the fluid level detector 24 needs to further detect the amount of cleaning fluid stored in the supply box 21, and compare the stored amount of cleaning fluid with the amount of cleaning fluid to be replenished through the comparison module 45. If the stored amount of cleaning fluid is greater than or equal to the amount of cleaning fluid to be replenished, the system enters the oil stain detection stage or the cleaning stage accordingly. If the stored amount of cleaning fluid is less than the amount of cleaning fluid to be replenished, the user is prompted to continue replenishing the cleaning fluid in the supply box 21. It is understood that the amount of cleaning fluid to be replenished mentioned in this application refers to the difference between the predetermined amount and the current stored amount before entering the oil stain detection stage; the amount of cleaning fluid to be replenished mentioned in this application refers to the difference between the total amount of cleaning fluid required and the predetermined amount after entering the oil stain detection stage.

[0102] For example, such as Figure 7 and Figure 8As shown, M1 represents the current liquid storage volume, and M2 represents the amount of cleaning fluid stored in the supply box 21 after replenishment. Specifically, before entering the oil stain detection stage, if M1 < V1, the user is prompted to continue replenishing the cleaning fluid until it exceeds the predetermined amount; if M1 ≥ V1, the oil stain detection stage is entered, and the supply device 20 is controlled to initially supply the predetermined amount of cleaning fluid to the volute 11, and the remaining pumping volume is determined based on the oil stain level determined by the oil stain detection.

[0103] More specifically, such as Figure 8 As shown, after entering the oil stain detection stage, if the detected level is extremely light oil stain, the required amount of cleaning fluid to be added is zero, and cleaning can begin directly. If the detected level is heavy oil stain, the required amount of cleaning fluid to be added is V3-V1. If M1≥V3, there is no need to add cleaning fluid to the supply box 21; the cleaning fluid is directly added to the volute 11 until V3 is reached, and cleaning begins. If M1<V3, the user will be prompted to add cleaning fluid to the supply box 21. Afterward, the liquid level detector 24 needs to detect the amount of cleaning fluid M2 stored in the supply box 21 after the cleaning fluid is added. If M1≥V3-V1, there is no need to add cleaning fluid to the supply box 21 again; the cleaning fluid is directly added to the volute 11 until V3 is reached, and cleaning begins. If M1<V3-V1, the user will be prompted to add cleaning fluid to the supply box 21 again.

[0109] It is worth noting that in step S200 of the adaptive cleaning method of this application: the measuring device measures the liquid level height h1 when the predetermined amount of cleaning fluid is added to the volute and the total amount of oil on the impeller in the current state. 总 The following relationship is satisfied between them:
