[0031] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element, or connected to the other element through an intermediate element. The "connection" in the following embodiments should be understood as "electrical connection", "communication connection", etc. if the connected circuits, modules, units, etc. have electrical signals or data transmission between each other.

[0032] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise.

At the same time, the terms used in this specification include any and all combinations of the relevant listed items.

[0033] In one embodiment, a range hood cleaning method is provided, which is suitable for cleaning the inner cavity of the range hood. Figure 1 As shown, the method includes:

[0034] Step S110: Detect whether a cleaning instruction is received.

[0035] Specifically, when the range hood is turned on and in working or standby mode, the controller can monitor in real time whether a cleaning instruction is received. The user can send a cleaning instruction to the controller through a cleaning button set on the touch screen of the range hood. The controller can use a separate control chip or the original control chip of the range hood.

[0036] Step S120: When a cleaning instruction is received, the electrostatic device is controlled to ionize the oil stains in the volute of the range hood.

[0037] Among them, the electrostatic device is arranged on the inner wall of the volute. After receiving the cleaning instruction sent by the cleaning button, the controller first controls the electrostatic device to ionize the oil stains in the volute of the range hood. Specifically, the electrostatic device can adopt a high-voltage electrostatic device, and the specific working voltage can be adjusted according to actual needs. Furthermore, the high-voltage electrostatic device can adopt a mesh structure distributed on the volute front plate, the volute rear plate and the volute enclosure, so as to more comprehensively ionize the oil stains attached to the volute. The high-voltage static electricity released by the high-voltage electrostatic device breaks up, emulsifies and peels off the oil stains and the oil film layer on the inner wall of the volute, thereby reducing the adhesion of the oil stains, so that when the oil stains in the volute are cleaned by ultrasonic waves, the oil stains can be made to fall off more easily.

[0038] Step S130: Control the ultrasonic generating device to vibrate and clean the volute.

[0039] The ultrasonic generator is connected to the volute. The ultrasonic generator can be fixed to the outside of the volute by means of screws or structures. After the controller controls the electrostatic device to complete the ionization of the oil in the volute of the range hood, it starts the ultrasonic generator to vibrate and clean the volute. Specifically, the ultrasonic generator may include an ultrasonic generator and an ultrasonic transducer. The controller controls the ultrasonic generator to output a square wave and converts it into a sine wave after matching and sends it to the ultrasonic transducer. The ultrasonic transducer transmits the sound wave to the volute through the amplitude rod and the vibration head for vibration cleaning.

[0040] The ultrasonic generator transmits vibration directly to the inside of the volute, thereby shaking off the oil and dust adhering to the volute, without using any cleaning fluid, which is green, environmentally friendly, safe and thoroughly cleans. In addition, fixing the ultrasonic generator on the outside of the volute can also prevent the ultrasonic generator from being corroded by oil and dirt, and does not hinder the operation of the range hood.

[0041] The above-mentioned range hood cleaning method, when receiving a cleaning instruction, first controls the electrostatic device to ionize the oil stains in the volute of the range hood to reduce the adhesion of the oil stains, and then controls the ultrasonic generating device to vibrate and clean the volute, thereby making it easier for the oil stains to fall off and be cleaned. No cleaning fluid is needed, and the method is green, environmentally friendly, safe, and cleans thoroughly, thereby improving the cleaning convenience of the range hood.

[0042] In one embodiment, after step S110, the method may further include: if no cleaning instruction is received, returning to step S110. If the controller does not receive a cleaning instruction sent by the user, it is not necessary to clean the inner cavity of the range hood, and the controller continues to detect whether a cleaning instruction is received.

[0043] In one embodiment, step S120 includes: when receiving a cleaning instruction, controlling the wind wheel in the volute to stop moving; controlling the electrostatic device to be powered on to generate high-voltage static electricity to ionize the oil stains attached to the inner wall of the volute. Specifically, after receiving the cleaning instruction, the controller first controls the motor in the volute to stop working so that the wind wheel stops mechanical movement to prevent the mechanical movement of the wind wheel from resonating with the ultrasonic generator, and then controls the electrostatic device to be powered on to generate high-voltage static electricity to ionize the oil stains attached to the inner wall of the volute.

[0044] Further, in one embodiment, step S130 includes: after the electrostatic device ionizes the oil in the volute for a preset time, controlling the ultrasonic generating device to operate, transmitting the vibration to the volute for vibration cleaning. Specifically, the specific value of the preset time is not unique. In this embodiment, the preset time is 30 seconds. The controller starts timing after starting the electrostatic device, and controls the ultrasonic generating device to operate after the ionization time reaches 30 seconds, transmitting the shock wave into the interior of the volute, thereby shaking off the oil and dust adhering to the volute. It can be understood that after starting the ultrasonic generating device, the electrostatic device can be turned off to stop ionization, or the electrostatic device can be allowed to continue ionization, so as to further improve the cleaning effect of the ultrasonic generating device when it is working.

[0045] In addition, in one embodiment, after the ultrasonic generator is controlled to work and the vibration is transmitted to the volute for vibration cleaning, step S130 may also include: after the ultrasonic generator has worked for a set time, the ultrasonic generator is controlled to stop working. Among them, the specific value of the set time is not unique. In this embodiment, the set time is 5 minutes. The controller starts timing when the ultrasonic generator is controlled to work, and controls the ultrasonic generator to stop working after the cleaning time reaches 5 minutes, and automatically turns off the cleaning function without manual operation by the user. It can be understood that if the electrostatic device is also working when the ultrasonic generator is working, the electrostatic device will be turned off synchronously when the ultrasonic generator is turned off.

[0046] In one embodiment, a range hood cleaning device is also provided, which is suitable for cleaning the inner cavity of the range hood. Figure 2 As shown, the device includes an instruction detection module 110 , an ionization control module 120 and a vibration control module 130 .

[0047] The instruction detection module 110 is used to detect whether a cleaning instruction has been received; the ionization control module 120 is used to control the electrostatic device to ionize the oil stains in the volute of the range hood when a cleaning instruction is received; wherein the electrostatic device is arranged on the inner wall of the volute; the vibration control module 130 is used to control the ultrasonic generating device to vibrate and clean the volute; wherein the ultrasonic generating device is connected to the volute.

[0048] In one embodiment, the instruction detection module 110 is further configured to detect again whether a cleaning instruction is received if no cleaning instruction is received.

[0049] In one embodiment, the ionization control module 120 is used to control the wind wheel in the volute to stop moving when receiving a cleaning instruction; control the electrostatic device to be energized to generate high-voltage static electricity to ionize the oil stains attached to the inner wall of the volute.

[0050] In one embodiment, the vibration control module 130 is used to control the operation of the ultrasonic generating device to transmit the vibration to the volute for vibration cleaning after the electrostatic device ionizes the oil in the volute for a preset time.

[0051] In addition, in one embodiment, the vibration control module 130 is also used to control the ultrasonic generating device to stop working after the ultrasonic generating device has worked for a set time.

[0052] The specific definition of the range hood cleaning device can be found in the definition of the range hood cleaning method above, which will not be repeated here. Each module in the above range hood cleaning device can be implemented in whole or in part by software, hardware, or a combination thereof. Each of the above modules can be embedded in or independent of a processor in a computer device in the form of hardware, or can be stored in a memory in a computer device in the form of software, so that the processor can call and execute the operations corresponding to each of the above modules.

[0053] When receiving a cleaning instruction, the above-mentioned range hood cleaning device first controls the electrostatic device to ionize the oil stains in the volute of the range hood to reduce the adhesion of the oil stains, and then controls the ultrasonic generating device to vibrate and clean the volute, thereby making it easier for the oil stains to fall off and be cleaned without using any cleaning fluid. It is green, environmentally friendly, safe and cleans thoroughly, thereby improving the cleaning convenience of the range hood.

[0054] In one embodiment, a range hood is also provided, including a volute, a wind wheel, an interactive device, an electrostatic device, an ultrasonic generating device and a controller, the electrostatic device and the wind wheel are arranged inside the volute, the ultrasonic generating device is connected to the volute, the controller is connected to the interactive device, the electrostatic device and the ultrasonic generating device, the interactive device is used to send a cleaning instruction to the controller, and the controller is used to clean the range hood according to the above method.

[0055] In one embodiment, the volute includes a volute front plate, a volute rear plate and a volute enclosure, and the volute front plate is fixed to the volute rear plate through the volute enclosure. Figure 3 As shown, the electrostatic device can adopt a high-voltage electrostatic net. Specifically, the electrostatic device is distributed on the volute front plate, the volute rear plate and the volute enclosure in a mesh structure, generating high-voltage static electricity to fully ionize the oil in the volute, thereby improving the ionization effect.

[0056] In one embodiment, the ultrasonic generating device includes an ultrasonic generator and an ultrasonic transducer, the ultrasonic transducer is disposed on the volute enclosure, and the ultrasonic generator is connected to the ultrasonic transducer and the controller. Figure 4As shown, the ultrasonic generator can also be set on the volute enclosure. The controller controls the ultrasonic generator to output a square wave and converts it into a sine wave after matching and sends it to the ultrasonic transducer. The ultrasonic transducer transmits the sound wave to the volute through the amplitude rod and the vibration head to vibrate and clean the volute.

[0057] The user can check the operating status of the range hood and control it through the interactive device, such as controlling the working mode and air volume of the range hood. The specific structure of the interactive device is not unique. In one embodiment, the interactive device is a touch screen. Furthermore, the touch screen also includes a cleaning button connected to the controller. The user can start the ultrasonic cleaning operation of the range hood by pressing the cleaning button.

[0058] When receiving a cleaning instruction, the above-mentioned range hood first controls the electrostatic device to ionize the oil stains in the volute of the range hood to reduce the adhesion of the oil stains, and then controls the ultrasonic generating device to vibrate and clean the volute, thereby making it easier for the oil stains to fall off and be cleaned without using any cleaning fluid. It is green, environmentally friendly, safe and cleans thoroughly, thereby improving the cleaning convenience of the range hood.

[0059] In order to facilitate a better understanding of the above-mentioned range hood cleaning method, device and range hood, a detailed explanation is given below in conjunction with specific embodiments.

[0060] The solution for cleaning the inner cavity of a range hood provided by the present application uses a high-voltage electrostatic device inside the volute of the range hood to ionize the oil and dirt that has accumulated in the volute for a long time, thereby reducing the adhesion of the oil and dirt. An ultrasonic generator is then connected and fixed to the volute, and the ultrasonic generator transmits vibration directly to the volute, thereby shaking off the oil and dirt and dust adhering to the volute. No cleaning agent is used, so it is more environmentally friendly and low-cost.

[0061] Specifically, Figure 3 The figure shows the high-voltage electrostatic device inside the volute. The high-voltage electrostatic device adopts a high-voltage electrostatic net, which is distributed on the volute front plate, volute rear plate and volute enclosure in a mesh structure. It is connected to the controller of the range hood for program control. The ultrasonic generating device can be started by using the cleaning button on the touch screen. The high-voltage static electricity released by the high-voltage electrostatic device breaks up, emulsifies and peels off the oil stains and oil film layers on the inner wall of the volute and the front and rear plates, thereby reducing the adhesion of the oil stains, thereby making it easier for the oil stains in the volute to fall off when ultrasonic cleaning is used.

[0062] like Figure 4The figure shows the installation diagram of the ultrasonic generator, which includes an ultrasonic generator and an ultrasonic transducer. The ultrasonic generator and the ultrasonic transducer are installed on the surface of the volute enclosure. The ultrasonic generator is connected to the controller of the range hood for program control. The ultrasonic generator can be started by using the cleaning button on the touch screen. The ultrasonic generator transmits vibration directly to the inside of the volute, thereby shaking off the oil and dust adhering to the volute.

[0063] like Figure 5 The figure shows the cleaning process of the range hood. When the cleaning function of the range hood is started, the wind wheel in the volute stops mechanical movement to prevent the mechanical movement of the wind wheel from resonating with the ultrasonic generator. The range hood controls the high-voltage electrostatic grid to energize and use the high-voltage electrostatic grid to ionize the oil attached to the volute. After ionization for 30 seconds, the controller of the range hood controls the ultrasonic generator to work and transmit the shock wave into the volute, thereby shaking off the oil and dust attached to the volute. After the ultrasonic generator works for 5 minutes, the cleaning function is automatically turned off.

[0064] The above-mentioned range hood does not use any cleaning fluid, is green, environmentally friendly and safe, cleans thoroughly, has a consistent cleaning effect and is low in cost, can clean the grease on the volute in time, ensures the interior of the range hood is clean and tidy, and improves the user experience.

[0065] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
