Description

Technical Field

[0001] The invention relates to the field of range hoods, and in particular to an automatic oil-removing and cleaning-free range hood device and a control method, equipment and storage medium. Background Art

[0002] In the application scenario of the kitchen, a large amount of oil will adhere to the blades of the range hood impeller after working for a long time. The attached oil will cause the power consumption of the range hood itself to increase, the noise caused by the unstable center of gravity of the impeller, and the oil is extremely difficult to clean.

[0003] There are two ways to solve the oil stain problem on the impeller of most range hoods on the market. One is to attach an oil-free coating to the impeller blades to reduce the adhesion of oil stains as much as possible, but the disadvantage is that the oil-free coating is expensive, resulting in high costs. The other method is to use steam to clean the oil stains on the impeller. The disadvantage is that it can only simply clean the impeller blades and cannot clean them thoroughly. There is also the problem of dealing with byproducts such as a large amount of accumulated water after cleaning. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic degreasing and cleaning-free range hood device and a control method, equipment, and storage medium to solve the problems of poor cleaning effect and the presence of by-products in the prior art range hood fan cleaning method.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] The invention discloses an automatic degreasing and cleaning-free range hood device, comprising a wind wheel and a jet device. The jet medium of the jet device is a non-aqueous medium, and the jet device emits a non-aqueous jet toward the blades of the wind wheel.

[0007] Furthermore, the jet device is movably mounted on the periphery of the wind wheel through a motion mechanism.

[0008] Furthermore, the motion mechanism includes a controllable linear motion mechanism, and the linear motion mechanism drives the jet device to perform linear back-and-forth motion around the periphery of the wind wheel.

[0009] Furthermore, the motion mechanism includes a controllable circumferential motion mechanism, and the circumferential motion mechanism drives the jet device to perform circumferential back-and-forth motion around the periphery of the wind wheel.

[0010] Furthermore, the motion mechanism includes a controllable telescopic motion mechanism, and the telescopic motion mechanism drives the jet device to move back and forth towards or away from the wind wheel.

[0011] Furthermore, the jet device is a plasma jet device.

[0012] Furthermore, the jet device is a cavitation jet device.

[0013] Furthermore, it is characterized in that the jet device is parallel to the outermost blade of the wind wheel.

[0014] Furthermore, the parallel spacing between the jet device and the outermost blade of the wind wheel is 6-10 mm.

[0015] A control method for an automatic degreasing and cleaning-free hood device comprises the following steps:

[0016] Step 1, starting the jet device to form a jet toward the wind wheel;

[0017] Step 2, obtaining the actual cleanliness value of the wind wheel acted upon by the jet;

[0018] Step 3, compare the actual cleanliness value of the wind wheel obtained in step 2 with the wind wheel cleanliness threshold value, and when the actual cleanliness value of the wind wheel is greater than or equal to the wind wheel cleanliness threshold value, stop the jet device from working; when the actual cleanliness value of the wind wheel is less than the wind wheel cleanliness threshold value, keep the jet device working, and re-obtain the actual cleanliness value of the wind wheel according to step 2, until the re-obtained actual cleanliness value of the wind wheel is greater than or equal to the wind wheel cleanliness threshold value, stop the jet device from working.

[0019] Furthermore, in step 2, the number of rotations of the wind wheel after the jet device is started and the number of times the wind wheel is acted upon by the jet are obtained, and the number of rotations of the wind wheel and the number of times the wind wheel is acted upon by the jet are multiplied to obtain the actual cleanliness value of the wind wheel.

[0020] Furthermore, in step 3, the wind wheel cleanliness threshold = oil pollution coefficient * running time of the wind wheel before the jet device is started.

[0021] An electronic device comprises a processor and a memory, wherein the memory stores program instructions, and the processor implements the steps of the above control method when running the program instructions.

[0022] A computer-readable storage medium stores program instructions, which implement the steps of the above control method when executed.

[0023] In the range hood of the present invention, a jet device is installed on the periphery of the fan wheel of the range hood, and the jet medium of the jet device is a non-aqueous medium. Specifically, the jet device adopts a plasma jet device or a cavitation jet device, so that the jet device can form a non-aqueous jet. The jet emitted by the jet device acts on the fan wheel blades of the range hood, and the oil stains on the fan wheel blades can be quickly and effectively removed. When the plasma jet device is used, a nano-level decontamination effect can also be achieved, which has the advantages of good decontamination effect and environmental friendliness.

[0024] In the range hood of the present invention, the jet device is movably mounted on the periphery of the wind wheel through a motion mechanism, thereby the position of the jet device can be adjusted to ensure the degreasing effect on the wind wheel blades, and by adjusting the position of the jet device, the interference with the wind wheel air volume can be minimized, thereby achieving effective degreasing of the wind wheel without affecting the wind wheel air volume as much as possible when the wind wheel is working.

[0025] In the range hood of the present invention, by setting a suitable position and distance relationship between the jet device and the outermost blades of the wind wheel, it can be ensured that the jet emitted by the jet device can effectively remove the oil stains on the wind wheel blades.

[0026] In the control method of the present invention, by setting the wind wheel cleanliness threshold and the actual cleanliness value of the wind wheel currently being cleaned by the jet, the jet action on the wind wheel is controlled based on the comparison result of the wind wheel cleanliness threshold and the actual cleanliness value of the wind wheel, thereby realizing automatic degreasing of the wind wheel in the range hood.

[0027] In summary, compared with the prior art, the present invention can achieve rapid and accurate removal of oil stains from the impeller of the range hood, and has a good degreasing effect, thereby solving the problem of oil stains adhering to the impeller. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 It is a schematic diagram of the structure of an embodiment of the device of the present invention.

[0029] Figure 2 It is a flowchart of an embodiment of the method of the present invention. DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0031] Embodiment 1

[0032] like Figure 1 As shown, this embodiment discloses an automatic degreasing and cleaning-free hood device, which includes a wind wheel 1, and a controllably movable plasma jet device 2 is installed on the periphery of the wind wheel 1. The plasma jet generated by the plasma jet device 2 acts on the oil stains on the blades of the wind wheel 1, so that the force of the plasma jet on the oil stains on the wind wheel 1 is greater than the adhesion force of the oil stains, thereby performing nano-level cleaning on the oil stains, allowing the oil stains to separate from the blades of the wind wheel 1 and enter the flue of the hood for discharge. Since the plasma jet device 2 is used, there are no excess by-products after removing the oil stains, and nano-level cleaning of the oil stains on the wind wheel 1 can be achieved.

[0033] In this embodiment, a motion mechanism is arranged on the periphery of the wind wheel 1, and the motion mechanism includes an electrically controlled slide device. The electrically controlled slide device is composed of a motion track 3, a slide slidably mounted on the motion track 3, and an electrical control system. The motion track 3 is fixed to the periphery of the wind wheel 1, and the slide moves back and forth along the motion track 3 under the control and drive of the electrical control system. The motion track 3 can be a linear track arranged on one side of the periphery of the wind wheel 1, whereby the electrically controlled slide device forms a linear motion mechanism. The motion track 3 can also be an annular track such as a circle or a square that surrounds the periphery of the wind wheel 1, whereby the electrically controlled slide device forms a circumferential motion mechanism.

[0034] In this embodiment, the motion mechanism further includes a telescopic motion mechanism 4, which includes a linear push rod motor and a mounting platform fixed on the output shaft of the linear push rod motor. The linear push rod motor is fixed on the slide in the electric control slide device, and the output shaft of the linear push rod motor moves back and forth towards or away from the wind wheel 1, thereby causing the mounting platform to move back and forth towards or away from the wind wheel 1.

[0035] In this embodiment, the plasma jet device 2 is mounted on a mounting table in the telescopic motion mechanism 4. Thus, the plasma jet device 2 can be driven to move back and forth around the periphery of the wind wheel 1 by the electrically controlled slide device, and the telescopic motion mechanism 4 can be used to make the plasma jet device 2 move back and forth toward or away from the wind wheel 1.

[0036] In this embodiment, the number of plasma jet devices 2 can be one or more. When there are multiple plasma jet devices 2, each plasma jet device 2 is respectively configured with a telescopic motion mechanism 4 and an electric-controlled slide device, or each plasma jet device 2 shares the same electric-controlled slide device, so that each plasma jet device 2 can move back and forth.

[0037] In this embodiment, the plasma jet device 2 is kept parallel to the outermost blade of the wind wheel 1, and the parallel spacing d between the plasma jet device 2 and the outermost blade of the wind wheel 1 is in the range of 6-10mm, thereby ensuring that the force exerted by the jet generated by the plasma jet device 2 on the oil stains on the blades of the wind wheel 1 is greater than the adhesion force of the oil stains. The smaller d is within the numerical range, the better the corresponding jet effect.

[0038] In order to achieve a nano-level cleaning effect in this embodiment, a plasma jet device 2 is used to perform a jet action on the wind wheel 1. In some application scenarios where the cleaning requirements are low and it is not necessary to achieve a nano-level cleaning effect, a cavitation jet device can be used to replace the plasma jet device 2, and it can also be achieved when removing oil stains on the blades of the wind wheel 1 without generating too many by-products.

[0039] In this example, the plasma jet device 2, the telescopic motion mechanism 4, and the electric-controlled slide device can all be controlled to work, that is, the plasma jet device 2, the telescopic motion mechanism 4, and the electric-controlled slide device can be controlled to work by electronic equipment. Among them, each time the plasma jet device 2 generates a jet toward the wind wheel 1, it means that the wind wheel 1 is acted upon by the jet once. By controlling the telescopic motion mechanism 4 and the electric-controlled slide device by electronic equipment, the plasma jet device 2 can be made to move back and forth accordingly to ensure that all blades of the wind wheel 1 are acted upon by the jet and thus remove oil stains. The electronic equipment can count the number of times the plasma jet device 2 works and the number of times the plasma jet device 2 moves back and forth through an internal counting program.

[0040] In this embodiment, a rotation sensor such as a rotary encoder can be integrated on the wind wheel. The rotation sensor can collect the rotation speed of the wind wheel. Thus, the electronic device can obtain the rotation speed of the wind wheel through the rotation sensor, and the electronic device can time the running time of the wind wheel through a timing program.

[0041] Embodiment 2

[0042] like Figure 2 As shown, this embodiment discloses a control method for a range hood device in the first embodiment. This embodiment is described by taking a plasma jet device 2 as an example, and includes the following steps:

[0043] Step 1: Make the telescopic motion mechanism and the electric-controlled slide device drive the plasma jet device 2 to make corresponding back-and-forth motion, and make the plasma jet device 2 start to emit plasma jets toward the wind wheel blades.

[0044] Step 2, obtaining the rotation speed V of the wind wheel after the plasma jet device 2 is started, the operating time t1 when the wind wheel rotates at the rotation speed V, and the number of times U when the wind wheel is acted upon by the jet, wherein the rotation speed V is the number of revolutions of the wind wheel per unit time.

[0045] Calculate the number of revolutions of the wind wheel Q = V * t1, and then calculate the actual cleanliness value of the wind wheel A = Q * U * N. Where N is the cleanliness coefficient, N represents the amount of oil pollution on a single blade per unit area cleaned by the plasma jet device 2 in a single unit time, and N is inversely proportional to the parallel spacing d between the plasma jet device 2 and the outermost blade of the wind wheel. The smaller d is, the larger the cleanliness coefficient N is.

[0046] Step 3: Compare the actual cleanliness value A of the wind wheel calculated in step 1 with the cleanliness threshold value B of the wind wheel. The cleanliness threshold value B of the wind wheel = oil pollution coefficient W * the running time t of the wind wheel before the plasma jet device 2 is started, wherein the oil pollution coefficient is a value obtained by multiple experiments, and the oil pollution coefficient represents the amount of oil pollution attached to the blade per unit time in a normal kitchen environment or an extreme kitchen environment.

[0047] The plasma jet device 2 is controlled based on the comparison result, and the process is as follows:

[0048] When the wind wheel actual cleanliness value A≥the wind wheel cleanliness threshold value B, the plasma jet device 2 is controlled to stop working, and the plasma jet device 2 is controlled to move back to the initial position.

[0049] When the wind wheel actual cleanliness value A is less than the wind wheel cleanliness threshold value B, the plasma jet device 2 is controlled to continue working, and the wind wheel actual cleanliness value A is recalculated according to step 2 and then compared again, until the wind wheel actual cleanliness value A is greater than or equal to the wind wheel cleanliness threshold value B, the plasma jet device 2 is stopped.

[0050] Embodiment 3

[0051] This embodiment discloses an electronic device for implementing the control method of embodiment 2, including a processor and a memory. The processor is used to receive data and control the operation of a plasma jet device 2, a telescopic motion mechanism 4, and an electrically controlled slide device. The memory stores program instructions that can be read and executed by the processor. When the processor executes the program instructions, steps 1-3 of the control method of embodiment 2 are implemented.

[0052] Embodiment 4

[0053] The fourth embodiment of the present invention discloses the storage medium of the memory in the third embodiment, and the storage medium stores program instructions, and the program instructions include a data processing module, a control instruction module, and a counting and timing module. The data processing module is used to obtain the wind wheel speed data, and perform multiplication and comparison, and generate work instruction data based on the comparison result and transmit it to the control instruction module; the control instruction module is used to generate control instruction data after receiving the work instruction data and transmit it to the plasma jet device, the telescopic motion mechanism, and the electric control slide device; the counting and timing module is used to time the wind wheel running time, and count the number of control instructions issued by the control instruction module, and transmit the timing and counting data to the data processing module. Therefore, when the program instructions are executed, steps 1-3 of the control method of the second embodiment are implemented.

[0054] The embodiments described in the present invention are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made to the technical solutions of the present invention by engineers and technicians in this field should fall within the protection scope of the present invention.
