[0052] Fans are easily contaminated by oil during use and require frequent cleaning. In related technologies, to achieve self-cleaning of fans, a cleaning structure with spray pipes and nozzles is generally installed on the volute to clean the fans.

[0053] In related technologies, when cleaning a blower, a cleaning structure with nozzles and spray nozzles is typically installed on the volute to introduce steam into the blower to soften the oil stains and clean the blower.

[0054] However, for fans with varying levels of oil contamination, the cleaning effect of a single steam cleaning mode is limited, resulting in poor cleaning performance.

[0055] Please see Figures 1 to 4 The present invention provides a control method for a kitchen appliance 300, the kitchen appliance 300 including a fan assembly 11 and a cleaning device 12, the fan assembly 11 including a volute 10, the volute 10 forming a receiving cavity 16 for accommodating an impeller 14, and the cleaning device 12 including a nozzle 18.

[0056] The control methods for kitchen appliance 300 include:

[0057] Step S01: Control the cleaning device 12 to deliver a first cleaning medium and / or a second cleaning medium into the nozzle 18 so that the first cleaning medium and / or the second cleaning medium are sprayed into the receiving cavity 16, wherein the first cleaning medium is different from the second cleaning medium.

[0058] The control method of the kitchen appliance 300 described above controls the cleaning device 12 to deliver different cleaning media to the nozzle 18, and different combinations of cleaning media can be used to clean the fan, thereby improving the cleaning effect of the cleaning device 12.

[0059] Specifically, the fan system 100 includes a fan assembly 11 and a cleaning device 12. The fan assembly 11 includes a volute 10 and an impeller 14, which together form a cavity 16. The impeller 14 is installed inside the cavity 16. When the fan assembly 11 is working, the impeller 14 rotates within the cavity 16, generating a strong airflow and creating a negative pressure zone. Due to the pressure difference, oil fumes are drawn in and discharged outdoors through the exhaust port. During this process, the impeller 14 frequently comes into contact with the oil fumes, causing the blades 15 and the volute 10 to fill the cavity 16 with oil.

[0060] To clean the inside of the fan assembly 11, a cleaning device 12 can be installed on the fan assembly 11, which sprays a cleaning medium onto the inner wall of the volute 10 and the impeller 14 for cleaning.

[0061] Meanwhile, for fan components 11 with different levels of oil contamination, different cleaning media or combinations of different cleaning media can be used for cleaning.

[0062] For example, the kitchen appliance 300 can be set with multiple cleaning modes. In the first cleaning mode, the cleaning device 12 is controlled to spray a first cleaning medium into the accommodating cavity 16; in the second cleaning mode, the cleaning device 12 is controlled to spray a second cleaning medium into the accommodating cavity 16; and in the third cleaning mode, the cleaning device 12 is controlled to spray both the first and second cleaning media into the accommodating cavity 16 simultaneously.

[0063] In this way, users can select the appropriate cleaning mode to clean the fan assembly 11 according to their cleaning needs and usage habits, thereby achieving a better cleaning effect.

[0064] Optionally, the first and second cleaning media can be in liquid, gaseous, or solid form, such as fluid, steam, or foam, etc. The types of cleaning media include, but are not limited to, water, detergent, grease remover, and other cleaning agents.

[0065] The nozzle 18 is used to spray cleaning medium into the accommodating cavity 16. In order to achieve the above function, the nozzle 18 can be set inside the accommodating cavity 16 and facing the impeller 14 and the inner wall surface of the volute 10.

[0066] Alternatively, the nozzle 18 can be located on the outside of the volute 10 and communicate with the interior of the receiving cavity 16 through openings or other means, so that the cleaning medium can be smoothly sprayed into the receiving cavity 16. In this way, the cleaning device 12 does not occupy the flow channel space inside the volute 10, which can avoid affecting the oil fume extraction effect of the fan system 100 to a certain extent.

[0067] Please see Figures 2 to 4 In one embodiment, the nozzle 18 is mounted on the outer wall of the volute 10. The nozzle 18 has a first fixing hole 32, and the volute 10 has a second fixing hole 34. The cleaning device 12 includes fasteners that pass through the first fixing hole 32 and the second fixing hole 34 to fix the nozzle 18 to the outer wall of the volute 10. This fastener fixation method is simple, stable, and reliable. On the one hand, the fasteners provide high reliability, preventing the nozzle 18 from loosening and displacing, which could lead to leakage of the cleaning medium. On the other hand, removable fasteners such as screws can be used for fixing, facilitating inspection, maintenance, and replacement of the nozzle 18. Optionally, a sealing ring can be provided between the fasteners and the outer wall of the volute 10 to prevent oil fumes inside the volute 10 from leaking through the second fixing hole 34.

[0068] The cleaning device 12 also includes a delivery pump 22, which is connected to the nozzle 18 to provide power for the cleaning medium to flow to the nozzle 18. Optionally, the cleaning device 12 also includes a steam generator 24, a heating element 26, a foaming machine, etc., which can enable the nozzle 18 to spray cleaning media in the form of steam, foam, etc., and at different temperatures into the receiving cavity 16.

[0069] Please see Figure 5 In some implementations, step S01 includes:

[0070] Step S011: Control the cleaning device 12 to deliver the first cleaning medium into the nozzle 18 until the first preset condition is met;

[0071] Step S013: When the first preset condition is met, control the cleaning device 12 to deliver the second cleaning medium into the nozzle 18 until the second preset condition is met;

[0072] Step S015: When the second preset condition is met, control the cleaning device 12 to deliver the first cleaning medium to the nozzle 18.

[0073] This allows for deep cleaning of the inside of the fan assembly 11.

[0074] Specifically, when cleaning the volute 10 and impeller 14, the cleaning device can first spray steam, hot water, or a mixture of steam and hot water into the receiving cavity 16 to initially soften the oil stains. After reaching the first preset condition, the output of the first cleaning medium is stopped. Then, detergent, which can be cold or hot, is sprayed into the receiving cavity 16 to dissolve the oil stains on the surface of the object being cleaned. After reaching the second preset condition, the output of the second cleaning medium is stopped. Finally, steam, hot water, or a mixture is sprayed into the receiving cavity 16 for rinsing.

[0075] The first and second preset conditions may include the spraying of cleaning media for a certain duration or the spraying amount of cleaning media reaching a certain value.

[0076] By supplying a first cleaning medium to the first inlet 36a, the inside of the fan can be initially cleaned. Then, by switching to the second inlet 36b to supply a second cleaning medium, the oil stains inside the fan can be further softened. By using different cleaning media in stages, cleaning resources can be utilized more effectively, ensuring that every part inside the fan is thoroughly cleaned.

[0077] Proceeding to the next step after the preset conditions are met ensures that the cleaning is neither overdone nor underdone, thereby improving the overall cleaning effect.

[0078] Please see Figure 6 In some implementations, step S01 includes:

[0079] Step S017: Control the cleaning device 12 to simultaneously deliver the first cleaning medium and the second cleaning medium to the nozzle 18.

[0080] In this way, cleaning efficiency can be improved.

[0081] Specifically, the cleaning device 12 simultaneously delivers two cleaning media, for example, the first cleaning medium is steam (or hot water or a mixture of steam and water), and the second cleaning medium is detergent. By simultaneously spraying steam (or hot water or a mixture of steam and water) and detergent into the accommodating cavity 16, the oil stains on the inner wall of the volute 10 and the impeller 14 can be softened and cleaned better, resulting in a better cleaning effect.

[0082] Simultaneous delivery of cleaning media enables comprehensive and rapid cleaning of the interior of the volute 10, while significantly reducing the cleaning time required. This not only improves cleaning efficiency but also reduces potential damage to the fan caused by prolonged cleaning.

[0083] In some embodiments, the ratio of the flow rates of the first cleaning medium and the second cleaning medium is determined based on the oil concentration of the fan system 100.

[0084] In this way, the cleaning device 12 can cope with different oil stain scenarios.

[0085] Specifically, the two cleaning media can be mixed in any proportion by adjusting the flow rates of the first and second cleaning media leading to the nozzle 18. For example, steam (or hot water or a mixture of steam and water) can be mixed in any proportion with detergent (cold or hot); or water and dish soap can be mixed in any proportion.

[0086] The ratio of the flow rates of the first cleaning medium and the second cleaning medium is determined by the oil concentration of the fan system 100. For example, in a light oil stain scenario, the detergent ratio is slightly smaller; in a heavy oil stain scenario, the detergent ratio is slightly larger, so that the cleaning device 12 can cope with different oil stain scenarios.

[0087] In some implementations, the weight or rotational speed of the impeller 14 can be detected, or the amount of oil on the impeller 14 can be detected using a sensor.

[0088] Please see Figure 7 In some implementations, step S017 includes:

[0089] Step S0171: Control the cleaning device 12 to deliver the first cleaning medium and the second cleaning medium into the nozzle 18 so that the first cleaning medium and the second cleaning medium are mixed in the nozzle 18 to form a mixed medium, and control the cleaning device 12 to spray the mixed medium into the receiving cavity 16.

[0090] Therefore, combining cleaning media with different cleaning functions can achieve better cleaning results.

[0091] Specifically, firstly, different cleaning media have different cleaning functions. Mixing cleaning media with different functions can effectively combine their cleaning effects to achieve better cleaning results. For example, mixing hot water and dish soap and then introducing it into the receiving cavity 16 allows the hot water to promote the release of the active ingredients in the dish soap, making it more effective at removing stains. The mixed dish soap solution can also break down and dissolve grease more quickly, thereby improving cleaning efficiency.

[0092] Secondly, some cleaning media have high concentrations and need to be diluted before use. By mixing and diluting in the nozzle 18, high-concentration cleaning media can be prevented from entering the receiving cavity 16. On the one hand, this can save the amount of such cleaning media used, and on the other hand, it can prevent high-concentration cleaning media from damaging the inner wall of the volute 10 and the impeller 14.

[0093] Finally, some cleaning media have high viscosity and poor flowability. If this type of cleaning media is introduced into the nozzle 18 alone, it may cause the cleaning media to clog the nozzle 18, causing the nozzle 18 to fail. Alternatively, the cleaning media may accumulate inside the accommodating cavity 16 and on the blades 15 of the impeller 14, and cannot be effectively dispersed and removed, resulting in cleaning media residue and increasing the cleaning burden.

[0094] In one implementation, such as Figure 2 and Figure 8 As shown, the nozzle 18 is disposed on the outer wall of the volute 10, and a through hole is formed on the volute 10. The nozzle 18 sprays the cleaning medium into the receiving cavity 16 through the through hole. The nozzle 18 is strip-shaped, and an inlet 36 is formed at one end along the length direction of the nozzle 18. A three-way pipe is installed at the inlet 36, which can realize the simultaneous introduction and mixing of two cleaning media in the nozzle 18.

[0095] Please see Figure 11 In some implementations, step S01 includes:

[0096] Step S019: Control the cleaning device 12 to deliver the first cleaning medium to the nozzle 18, while simultaneously stopping the delivery of the second cleaning medium to the nozzle 18; or

[0097] Step S021: Control the cleaning device 12 to deliver the second cleaning medium to the nozzle 18, and at the same time stop delivering the first cleaning medium to the nozzle 18.

[0098] This allows for a wider variety of cleaning modes for 300 kitchen appliances.

[0099] Specifically, the volute 10 and impeller 14 can be cleaned by spraying a single cleaning medium into the accommodating cavity 16. When there is little oil inside the fan, a single cleaning medium can be used to clean the inside of the fan, which can reduce potential damage to the fan caused by prolonged cleaning.

[0100] In one implementation, such as Figures 12 to 14 As shown, the nozzle 18 is disposed on the outer wall of the volute 10, and a through hole is formed on the volute 10. The nozzle 18 sprays the cleaning medium into the receiving cavity 16 through the through hole. The nozzle 18 is strip-shaped, with a first inlet 36a and a second inlet 36b respectively formed at both ends along the length of the nozzle 18. One-way valves are installed on the delivery pipes 38 connecting the first inlet 36a and the second inlet 36b, respectively. Alternatively, a partition is set in the middle along the length of the nozzle 18, so that the cleaning medium delivered by different delivery pipes 38 can be controlled to flow into the nozzle 18 and spray into the receiving cavity 16 through the first inlet 36a and the second inlet 36b respectively.

[0101] Please see Figure 15 In some implementations, the control method includes:

[0102] Step S03: When the first cleaning medium and / or the second cleaning medium are stopped being delivered into the accommodating cavity 16, the impeller 14 is controlled to run for a preset time.

[0103] In this way, the impeller 14 can be rotated to dry the cavity 16, thus ensuring a clean environment inside the cavity 16 and avoiding affecting the oil fume extraction effect of the fan assembly 11.

[0104] Specifically, during the cleaning of the fan assembly 11, the impeller 14 can rotate, or the impeller 14 can remain stationary. After the cleaning stage of the fan assembly 11 is completed, the impeller 14 can be controlled to rotate to dry the cleaning medium in the accommodating cavity 16, preventing residual cleaning medium in the accommodating cavity 16 from causing odors if the kitchen appliance 300 is not used for a long time; or, preventing the use of the kitchen appliance 300 when the humidity in the accommodating cavity 16 is high, which may affect the oil fume extraction effect of the fan assembly 11.

[0105] In some implementations, the control method includes:

[0106] Step S05: While controlling the cleaning device 12 to deliver the first cleaning medium into the nozzle 18 and / or to deliver the second cleaning medium into the nozzle 18, control the impeller 14 to rotate continuously, or control the impeller 14 to rotate intermittently.

[0107] This will make the cleaning effect better.

[0108] Specifically, the impeller 14 rotates continuously or intermittently within the accommodating cavity 16, which can agitate the cleaning medium within the accommodating cavity 16, thereby increasing the contact area between the cleaning medium and the inner wall of the volute 10 and the blades 15 of the impeller 14, achieving the effect of cleaning the impeller 14 and the inner wall of the volute 10 through the circulation of the cleaning medium.

[0109] As the impeller 14 continues to rotate, it can agitate the cleaning medium in the accommodating cavity 16 and make the cleaning medium circulate in the accommodating cavity 16, which has a scouring effect on the blades 15 of the impeller 14 and the inner wall of the volute 10.

[0110] When the impeller 14 rotates with a gap, the cleaning medium has two states in the accommodating cavity 16: static and flowing. In the static state, it can soak the blades 15 and the inner wall of the volute 10 to remove oil stains. In the flowing state, the cleaning medium circulates in the accommodating cavity 16 and has a scouring effect on the blades 15 of the impeller 14 and the inner wall of the volute 10.

[0111] Please see Figure 16 In some embodiments, the nozzle 18 is fixed to the outside of the volute 10, and the cleaning device 12 further includes a spray channel 20. The nozzle 18 is configured to spray cleaning medium into the accommodating cavity 16 through the spray channel 20. The spray channel 20 is inclined toward the impeller 14 relative to the rotation axis of the vertical impeller 14. Step S01 includes:

[0112] Step S023: In the first cleaning mode, the cleaning device 12 is controlled to deliver the first cleaning medium and / or the second cleaning medium to the nozzle 18, while the impeller 14 is controlled to rotate at the first speed.

[0113] Step S025: In the second cleaning mode, the cleaning device 12 is controlled to deliver the first cleaning medium and / or the second cleaning medium to the nozzle 18, while the impeller 14 is controlled to rotate at a second speed, where the first speed is less than the second speed.

[0114] Thus, by controlling the rotational speed of the impeller 14, the contact position between the spray channel 20 and the impeller 14 can be controlled, thereby increasing the contact area between the cleaning medium and the impeller 14.

[0115] Specifically, the nozzle 18 sprays the cleaning medium from the receiving cavity into the receiving cavity 16 through the spray channel 20, thereby cleaning the inner wall of the receiving cavity 16 and the impeller 14 inside the receiving cavity 16. The nozzle 18 is located on the outer wall of the volute 10, which avoids the nozzle 18 occupying the flow channel space inside the receiving cavity 16, and to a certain extent avoids affecting the oil fume extraction effect of the fan system 100.

[0116] The spray channel 20 is inclined toward the impeller 14 relative to the rotation axis of the vertical impeller 14, so that the spray direction of the nozzle 18 is toward the blades 15 of the impeller 14, allowing the cleaning medium to better contact the blades 15, thereby improving the cleaning effect of the cleaning device 12.

[0117] like Figure 2 and Figure 10As shown in the figure, the H direction is parallel to the rotation axis of the impeller 14, and the V direction is perpendicular to the rotation axis of the impeller 14.

[0118] With the spray channel 20 tilted at a certain angle α to the axis of rotation of the vertical impeller 14, and the length direction of the nozzle 18 parallel to the axis of rotation of the impeller 14, the cleaning medium sprayed from the spray channel 20 can contact the concave surface of the blades 15 of the impeller 14. Simultaneously, when the impeller 14 rotates at high speed, the cleaning medium sprayed from the spray channel 20 can also contact the back surface of the blades 15. Thus, the contact area between the cleaning medium and the blades 15 is large, resulting in a better cleaning effect.

[0119] In summary, the first cleaning mode of the kitchen appliance 300 can be a mode for cleaning the concave surface of the blade 15. In the first cleaning mode, the impeller 14 is controlled to rotate at a medium-low speed, which allows the cleaning medium to contact the concave surface of the blade 15 for cleaning. The second cleaning mode of the kitchen appliance 300 can be a mode for cleaning the back side of the blade 15 (i.e., the side opposite to the concave surface). In the second cleaning mode, the impeller 14 is controlled to rotate at a high speed, which allows the cleaning medium to contact the back side of the blade 15 for cleaning.

[0120] Please see Figure 17 In some implementations, the control method includes:

[0121] Step S05: When the third preset condition is met by the control cleaning device 12 supplying the first cleaning medium to the nozzle 18 and / or supplying the second cleaning medium to the nozzle 18, the impeller 14 is controlled to rotate.

[0122] This enriches the cleaning modes of the kitchen appliance 300 and enhances the cleaning effect of the cleaning device 12.

[0123] Specifically, in order to effectively clean the inner wall of the volute 10 and the impeller 14, during the cleaning process, the impeller 14 can be kept stationary first, and the first cleaning medium and / or the second cleaning medium can be sprayed out to cover most of the impeller 14 and the volute 10. Then, the impeller 14 can be started to rotate continuously or intermittently to achieve the effect of media flow and circulation cleaning.

[0124] The third preset condition includes, but is not limited to, the continuous spraying duration of the cleaning medium and the current flow rate of the cleaning medium.

[0125] In summary, when the kitchen appliance 300 controls the cleaning device 12 to clean the fan assembly 11, it can control the nozzle 18 to spray one or both of the first and second cleaning media onto the inner wall of the volute 10 and the impeller 14.

[0126] When using both cleaning media simultaneously, the two cleaning media can be mixed in the nozzle 18 first to improve the cleaning effect.

[0127] Meanwhile, by controlling the spraying sequence and flow rate of the first and second cleaning media, as well as the different combinations of the working state of the impeller 14, the kitchen appliance 300 has a variety of different cleaning modes, suitable for different oil stain conditions of the fan components 11 and user habits, thus making the kitchen appliance 300 more practical and with better cleaning effect.
