[0047] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0048] The terms “a,” “one,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “include” and “have” are used to indicate an open-ended meaning of inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.

[0049] This utility model embodiment provides a range hood, such as Figure 1-8As shown, the range hood includes a main body 1, an oil cup 2, a water cup 3, and a cleaning system 4. The bottom of the oil cup 2 has an oil guide hole 20. The water cup 3 is divided into a clean water zone 300 and a wastewater zone 301 by a partition. The clean water zone 300 has an inlet, and the wastewater zone 301 has a drain outlet. The oil cup 2 is connected to the bottom of the main body 1, and the water cup 3 is connected to the bottom of the oil cup 2. The cleaning system 4 connects the clean water zone 300 and the interior of the main body 1. The wastewater zone 301 is connected to the interior of the oil cup 2 through the oil guide hole 20. Specifically, after the range hood has been operating for a certain period, such as 40-60 hours, the cleaning process can be initiated. First, the oil in the oil cup 2 is directed into the wastewater zone. The oil in the wastewater zone 301 can be discharged to the outside of the range hood 1 through its drain outlet, for example, directly into the kitchen drain pipe or into a dedicated wastewater container. This application does not impose any restrictions on this. As the grease in the oil cup 2 flows out, the cleaning system 4 opens, spraying the cleaning fluid in the clean water zone 300 into the interior of the range hood body 1. The clean water zone 300 can be connected to a cleaning fluid container or other water source through the inlet to clean the interior of the range hood. During the cleaning process, grease or excess cleaning fluid in the range hood body 1 can automatically enter the wastewater zone 301 through the oil cup and oil guide hole 20. Grease in the wastewater zone 301 can be discharged to the outside of the range hood 1 through the drain outlet. Throughout the process, there is no need to disassemble the oil cup 2 and water cup 3, making it less likely to lose anything and enabling automated cleaning. In addition, the oil cup 2 does not need to be disassembled frequently, reducing the sealing requirements for grease at the bottom of the entire casing and simplifying the overall structure. The heating component 5 reduces the viscosity of the grease, making it easier to clean. The range hood has a good cleaning effect and high cleaning efficiency, enabling fully automatic cleaning of the range hood.

[0050] In addition, the range hood may also include a heating component 5 and a control component. The heating component 5 includes a first heating part 51 for heating the oil cup 2. The control component is connected to the heating component 5 and the cleaning system 4. The control component controls the heating component 5 and the cleaning system 4 to cooperate with each other to automatically complete the cleaning and drainage of the range hood body 1. Specifically, considering that the range hood is turned on for cleaning after a certain period of operation, such as 40 to 60 hours, the oil in the oil cup 2 may be relatively viscous and difficult to clean and drain. The first heating part 51 can heat the viscous oil in the oil cup 2 to turn it into a flowable liquid, which then enters the wastewater area through the oil guide hole 20 on the oil cup 2. The oil in the wastewater area 301 can be discharged to the outside of the range hood 1 through the drain outlet, for example, directly into the kitchen drain pipe through the drain pipe or into a special wastewater container. This application does not impose any restrictions on this. Next, the control system controls the cleaning system 4 to open, and the cleaning liquid in the clean water zone 300 is sprayed into the interior of the range hood body 1 for cleaning. During the cleaning process, the oil stains or excess cleaning liquid in the range hood body 1 can automatically enter the sewage zone 301 through the oil cup and oil guide hole 20. The oil stains in the sewage zone 301 can be discharged to the outside of the range hood 1 through the drain outlet.

[0051] Preferably, the heating component 5 also includes, for example, Figure 3-4 The second heating element 52 shown is located on the inner bottom of the range hood body 1. It is used to heat the grease inside the range hood body 1, promoting the flow of grease into the grease cup 2. Figure 3 and 4 The heating component 5 shown is an L-shaped heating rod. Its horizontal section is located at the bottom of the oil cup 2, and its vertical section is the second heating part 52 inserted into the bottom inner side of the range hood body 1. By heating the inside of the range hood body 1, the viscosity of the oil is reduced, making it easier to flow out and improving the cleaning effect. This application optimizes the design of the cleaning structure, including the water cup 3, oil cup 2, and heating component 5, by adopting an integrated design. This eliminates the need for disassembly of the oil cup 2 and water cup 3 during the cleaning process, avoiding the risk of losing parts and achieving an automated cleaning process. This design has the following significant advantages: the oil cup 2 adopts a fixed design, greatly reducing the frequency of disassembly, thereby reducing the oil sealing requirements at the bottom of the entire machine casing and simplifying the overall structure; the heating component 5 effectively reduces the viscosity of the oil, significantly improving the oil removal efficiency; the entire cleaning process is fully automated, not only providing excellent cleaning results but also realizing the intelligent self-cleaning function of the range hood. Therefore, this design significantly improves the ease of use and reliability of the product while ensuring cleaning efficiency.

[0052] In a preferred embodiment of this utility model, such as Figure 1 , 3As shown in Figure -4, the control component also includes a solenoid valve 6, a temperature sensor, and a level control component. The solenoid valve 6 is connected to the oil guide hole 20 and is used to control the opening and closing of the sewage zone 301 in the oil cup 2. The temperature sensor is connected to the oil cup 2 and is used to detect the temperature of the oil in the oil cup 2. The level control component is connected to the oil cup 2 and is used to detect whether the oil in the oil cup 2 is at the minimum level. The control component is connected to the temperature sensor and the level control component. The control component opens the solenoid valve 6 based on the signals from the heating component 5 and the temperature sensor, and controls the opening and closing of the cleaning system 4 based on the signal from the level control component. Specifically, when the heating component 5 is turned on, the solenoid valve 6 can be closed initially to prevent oil from entering the sewage zone and carrying away heat, so that the viscosity of the oil in the oil cup can be reduced as a whole and flow out. Since the viscosity of oil is highly dependent on temperature, this application utilizes a temperature sensor to measure the temperature of the oil and determines its state based on the temperature. For example, in this application, when the oil temperature is between 40°C and 60°C, the control component opens the solenoid valve 6, allowing the oil in the oil cup 2 to enter the wastewater zone 301. During this process, the level control component can monitor in real time whether the level in the oil cup 2 is at the minimum level. When the oil cup 2 is at the minimum level, the oil in the oil cup 2 has been mostly discharged. At this point, the cleaning system 4 can be opened to clean the range hood. After cleaning is completed, the solenoid valve 6 is closed.

[0053] In a preferred embodiment of this utility model, such as Figure 3-4 The cleaning system 4 shown in Figures 5 includes a water spraying component and a water inlet component 41. The water spraying component is connected to the top of the range hood body 1 and is used to spray water into the interior of the range hood body 1. One end of the water inlet component 41 is connected to the clean water zone 300, and the other end is connected to the water inlet end of the water spraying component through a flexible water pipe. The water outlet direction of the water inlet component 41 is perpendicular to its water inlet direction. The water spraying component includes a water pump and a nozzle installed on the top of the range hood body 1. After the water pump is turned on, the water suction component 41 can transport the cleaning liquid in the clean water zone 300 to the nozzle to clean the interior of the range hood. The unique structural design of the water inlet component 41, with its water outlet direction perpendicular to its water inlet direction, is to change the water inlet direction from vertical to horizontal, achieving an efficient conversion of the water flow direction from vertical to horizontal. This avoids the flow loss caused by the bending of traditional flexible hoses and ensures smooth delivery of the cleaning liquid. In addition, it can reduce fluid resistance, allowing the cleaning liquid to be delivered to the nozzle stably and efficiently, thereby ensuring overall cleaning efficiency.

[0054] In a preferred embodiment of this utility model, such as Figure 3-4The water inlet component 41 shown in Figures 5 and 8 includes a water inlet assembly 411, an upper connecting pipe 412, and a lower connecting pipe 413. The water inlet assembly 411 is connected to the bottom inner side of the range hood body 1. The top of the upper connecting pipe 412 is inserted into the bottom of the range hood body 1 and connected to the water inlet end of the water inlet assembly 411. The bottom of the upper connecting pipe 412 is sealed and connected to the bottom of the oil cup 2. The top of the lower connecting pipe 413 passes through the oil cup 2 and is inserted into the upper connecting pipe 412. The bottom of the lower connecting pipe 413 is inserted into the clean water zone 300. The oil cup 2 has a mounting hole 23 at its bottom for installing the upper connecting pipe 412 and the lower connecting pipe 413. The mounting hole 23 is a stepped hole. The upper connecting pipe 412 is inserted into and sealed to the first stepped surface of the mounting hole 23. The top of the lower connecting pipe 413 is inserted into the mounting hole 23 and the upper connecting pipe 412. Specifically, the top of the lower connecting pipe 413 is sealed to the oil cup 2, ensuring that the cleaning fluid in the cleaning zone 300 can smoothly enter the water inlet assembly 411 through the lower connecting pipe 413 and the upper connecting pipe 412. By connecting the upper connecting pipe 412 and the lower connecting pipe 413 in sections, the automatic cleaning function can be achieved without disassembling the oil cup 2.

[0055] In a preferred embodiment of this utility model, such as Figure 2-8 The water cup 3 shown also includes a first flange 31, an L-shaped block 32, and a stop block 33. The first flange 31 is formed by bending the top of the water cup 3 outward. The L-shaped block 32 includes a vertical part 321 and a horizontal part 322 connected to the top of the vertical part 321. The vertical part 321 is connected to the side of the first flange 31 away from the water cup 3, and the horizontal part 322 is located above the first flange 31. The stop block 33 is connected to the front side of the first flange 31 and the L-shaped block 32. The first flange 31, the L-shaped block 32, and the stop block 33 together form an installation groove 30. The bottom of the oil cup 2 is provided with a hook 21 for cooperating with the water cup 3. The hook 21 can be inserted into the installation groove 30 to realize the connection between the water cup 3 and the oil cup 2. The structure of the first flange 31, L-shaped block 32 and stop block 33 in this application not only increases the structural strength of the water cup 3, but also forms an installation groove 30 that matches the hook 21. The structure is ingenious and facilitates the assembly and maintenance of the water cup 3 and oil cup 2. If a problem occurs, only the corresponding parts need to be replaced.

[0056] Preferably, the top of the front wall of the water cup 3 is provided with a second flange 34 that extends from bottom to top and outwards at an angle, which can guide the flow; the two ends of the second flange 34 and the stop block 33 are provided with connecting parts to enhance the connection strength between the mounting groove 30 and the water cup 3.

[0057] In a preferred embodiment of this utility model, such as Figure 3 , 4The bottom of the hook 21, as shown in Figure 7, has a limiting groove for mounting the hook 21. The hook 21 includes a mounting block 211 and an ear piece 212. The mounting block 211 is connected to the bottom of the oil cup 2. The limiting groove 22 has its opening facing downwards, and the mounting block 211 is inserted into and bolted to the limiting groove 22. One side of the ear piece 212 is connected to the bottom of the mounting block 211, and the other side of the ear piece 212 extends outwards and can be inserted into the mounting groove 30. In this application, there are two ear pieces 212, which are symmetrically distributed on both sides of the bottom of the mounting block 211. During installation, there is no need to distinguish the direction, which improves the installation efficiency of the hook 21 and the oil cup 2. In addition, the mounting block 211 and the two ear pieces 212 are integrally formed, so that the longitudinal section of the hook 21 is "U" shaped. This not only reduces the overall weight of the hook 21, but also increases the structural stability of the hook 21, significantly improves its mechanical properties and lightweight level, ensures higher load-bearing stability, enhances overall strength, and extends the service life of the hook 21. Furthermore,

[0058] like Figure 3 , 4 As shown in Figure 7, the horizontal part 322 has a chamfer 3221 on one side near the ear piece 212. The inclined surface of the chamfer 3221 slopes towards the inside of the water cup 3 from back to front. The inclined surface of the chamfer 3221 can significantly reduce the assembly resistance, making it easier for the hook to slide smoothly into the slot, solving the alignment problem in the assembly process, and improving the reliability and service life of the product.

[0059] In a preferred embodiment of this utility model, the top surface of the horizontal part 322 has multiple grooves 3222 facing downwards, and the top of the mounting block 211 has a rectangular groove 2111 facing downwards. An annular wall 2112 is provided inside the rectangular groove 2111, and a second reinforcing rib 2113 is provided between the annular wall 2112 and the inner wall of the rectangular groove 2111. The bottom center of the rectangular groove 2111 is bolted to the limiting groove 22. Both the multiple grooves 3222 and the rectangular groove 2111 are designed to achieve the dual effects of lightweighting and structural reinforcement. In particular, the annular wall 2112 and the second reinforcing rib 2113 inside the rectangular groove 2111 significantly improve the bending stiffness of the hook 21, ensuring overall structural strength while reducing weight, and guaranteeing the connection stability between the hook 21 and the water cup 3.

[0060] In a preferred embodiment of this utility model, such as Figure 2-7 A first reinforcing rib 311 is provided between the bottom of the first flange 31 and the water cup 3, which increases the structural strength between the bottom of the first flange 31 and the water cup 3 and ensures higher load-bearing stability.

[0061] This utility model embodiment provides a range hood, such as Figure 9-10 As shown, a range hood includes...

[0062] Step S100: Determine if the range hood's running time has reached the preset time; if so, activate the heating component 5 to heat the range hood body 1 and oil cup 2. The control component acquires the cumulative running time of the range hood in real time. When the running time reaches the preset time T, it indicates that the range hood needs cleaning. At this time, the control system activates the heating component 5 to heat the range hood body 1 and oil cup 2, reducing the viscosity of the oil stains in the range hood body 1 and oil cup 2 so that they flow into the wastewater area 301. It should be noted that the preset time T can be any value within 40 to 100 hours, such as 50 hours, 60 hours, 70 hours, etc. Users can set it according to their cooking habits. For example, stir-frying and deep-frying produce more oil fumes, so the cleaning interval can be reduced to avoid excessive oil stains in the range hood body 1, which would increase the difficulty of cleaning.

[0063] Step S200: Detect whether the temperature of the oil in oil cup 2 meets the preset temperature; if it does, open solenoid valve 6 to allow the oil in oil cup 2 to enter wastewater zone 301; if it does not meet the preset temperature, close solenoid valve 6 and continue heating with heating component 5 until the temperature of the oil in oil cup 2 meets the preset temperature. Since the viscosity of oil is highly dependent on temperature, a temperature sensor is used to measure the temperature of the oil, and the state of the oil is determined based on the temperature, thereby prompting the oil in oil cup 2 to flow into wastewater zone 301. After heating component 5 is turned on, the viscosity of the oil gradually decreases, and solenoid valve 6 closes to allow the solidified oil to liquefy upon heating, ensuring a smoother discharge process and preventing blockage of oil guide hole 20 or drain pipe. Therefore, this application ensures that the oil reaches the optimal discharge viscosity before initiating the discharge procedure, further optimizing cleaning efficiency and energy consumption balance.

[0064] Step S300: Detect and determine whether the liquid level in the oil cup 2 is at the minimum level; if so, open the cleaning system 4 to clean the range hood body 1; as the solenoid valve 6 opens, the oil in the oil cup 2 begins to enter the wastewater zone 301. During this process, the liquid level component can monitor in real time whether the liquid level in the oil cup 2 is at the minimum level. When the oil cup 2 is at the minimum level, the oil in the oil cup 2 is completely discharged. At this time, the cleaning system 4 can be opened to clean the range hood. The oil washed down during the cleaning process enters the oil cup 2 and the wastewater zone 301 in sequence and is then discharged to the outside of the range hood, achieving an efficient and thorough automatic cleaning process.

[0065] Step S400: After the cleaning system 4 finishes working, close the solenoid valve 6 and reset the range hood's running time. As the cleaning system 4 finishes working, the discharge of grease from the main body 1 of the range hood and the grease cup 2 is gradually completed. At this point, closing the solenoid valve 6 is sufficient. Resetting the range hood's running time is to establish a timing benchmark for the next cleaning cycle, thus realizing a complete working cycle of the cleaning system. This ensures both equipment reliability and the accuracy of the maintenance cycle.

[0066] In a preferred embodiment of this utility model, such as Figure 9-10 As shown, after the heating component 5 is started, the temperature sensor detects the temperature of the oil in the oil cup 2, and opens the solenoid valve 6 when the oil temperature reaches 40° to 60°. The oil temperature θ can be 40° to 60°, preferably 45°. At this time, the viscosity of the grease is greatly reduced, which makes it convenient, fast and efficient to clean the oil in the range hood.
