[0031] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0032] Range hoods, as a common kitchen appliance, are widely used in kitchens to quickly remove and exhaust cooking fumes outdoors. During operation, grease and grime adhere to the inside of the range hood, and over time, this can cause grease and grime to drip from the internal walls onto the stovetop or clog the grease filter, thus affecting the range hood's performance. Therefore, regular cleaning of the range hood's interior is necessary. Currently, cleaning range hoods mainly relies on manual labor, which is time-consuming, laborious, and results in a poor user experience. Some range hoods have automatic cleaning devices, but these devices often have insufficient water flow and can only spray one type of cleaning agent, leading to poor cleaning effectiveness inside the range hood.

[0033] To address the aforementioned technical problems, this application provides a range hood that can select a suitable cleaning method based on the degree of grease buildup inside the hood, automatically cleaning the interior to avoid the time-consuming and laborious nature of manual cleaning, improve cleaning effectiveness, and thus enhance the user experience. The specific details of the range hood are further described below with reference to the accompanying drawings.

[0034] Figure 1 A schematic diagram of the structure of a range hood 100 in one or more embodiments of this application is shown. Figure 2 It shows Figure 1 Another structural diagram from the perspective of Figure 3 A schematic diagram of the structure of the spray pipe 120 is shown. Figure 4 A schematic diagram of the internal structure of the spray pipe 120 is shown. (Combined with...) Figures 1-4The range hood 100 includes a body 110, a spray pipe 120, a first heater 130, and a second heater 140. The spray pipe 120 is connected inside the body 110 and has spray holes 121. The first heater 130 is located inside the body 110 and is in fluid communication with the spray pipe 120. The second heater 140 is located inside the spray pipe 120.

[0035] The range hood 100 provided in this application has a spray pipe 120 connected inside the body 110. The spray pipe 120 has spray holes 121, and the cleaning consumables delivered to the spray pipe 120 can be sprayed into the body 110 through the spray holes 121. Since the first heater 130 is located inside the body 110 and is in fluid communication with the spray pipe 120, and the second heater 140 is located inside the spray pipe 120, the cleaning consumables can be heated once by the first heater 130 and then heated a second time by the second heater 140, so that the cleaning consumables can be sprayed out in the form of high temperature and high pressure, thereby improving the cleaning effect on the inside of the body 110 and having good practicality.

[0036] Combination Figure 1 as well as Figure 2 The spray pipe 120 is arranged along the height direction of the body 110. One end of the spray pipe 120 is connected to the top of the body 110, and the other end of the spray pipe 120 is connected to the bottom of the body 110, so that the cleaning consumables sprayed by the spray hole 121 of the spray pipe 120 can be sprayed to the entire inner wall of the body 110, ensuring the cleaning range of the inner wall of the body 110, thereby improving the cleaning effect of the inside of the body 110.

[0037] Combination Figure 1 as well as Figure 2 Two spray pipes 120 are provided, arranged opposite each other along the width of the machine body 110. The two spray pipes 120 increase the amount of cleaning consumables sprayed into the machine body 110, improving cleaning efficiency and further ensuring a larger cleaning area on the inner wall of the machine body 110, thus enhancing the cleaning effect inside the machine body 110.

[0038] Combination Figure 1 as well as Figure 2 The range hood 100 also includes a fan 150, which is located inside the body 110. The fan 150 is provided with an air inlet 151, that is, the fan 150 has an air inlet side 152. Two spray pipes 120 are arranged opposite to the air inlet side 152 of the fan 150. The cleaning consumables output by the two spray pipes 120 can be sprayed onto the air inlet side 152 of the fan 150 to clean the air inlet side 152 of the fan 150. In addition, the cleaning consumables can also enter the interior of the fan 150 through the air inlet 151 of the fan 150 to clean the interior of the fan 150.

[0039] Combination Figure 1 as well as Figure 2 Along the opening direction of the air inlet 151 of the fan 150, the projections of the two spray pipes 120 on the air inlet side 152 of the fan 150 fall on both sides of the air inlet 151 of the fan 150, so as to avoid the spray pipes 120 facing the air inlet 151 of the fan 150 directly, which would affect the air intake and smoke extraction effect of the fan 150.

[0040] In one embodiment, the spray pipe 120 is rotatably connected to the machine body 110. By controlling the rotation of the spray pipe 120, the spray range of the spray pipe 120 can be increased, the spray speed and uniformity of the cleaning consumables can be accelerated, and the cleaning consumables can be sprayed at different angles to rinse the inside of the machine body 110, thereby improving the cleaning effect on the inside of the machine body 110.

[0041] In one embodiment, the spray pipe 120 can oscillate back and forth within a certain range. While ensuring the spray range of the spray pipe 120, cleaning consumables can also be sprayed at different angles to rinse the inside of the machine body 110, thereby improving the cleaning effect on the inside of the machine body 110. Of course, when cleaning the inside of the range hood, the spray pipe 120 can also be controlled to be fixed at a certain time and oscillate at a certain time according to the program instructions.

[0042] Since the air inlet side 152 and the interior of the fan 150 are the most difficult areas to clean, in one embodiment, the spray pipe 120 has denser spray holes 121 on the side facing the air inlet side 152 of the fan 150, so that more cleaning consumables can be output to the air inlet side 152 and the interior of the fan 150, focusing on cleaning the air inlet side 152 and the interior of the fan 150, thereby improving the cleaning effect on the air inlet side 152 and the interior of the fan 150.

[0043] Combination Figure 1 as well as Figure 2In one embodiment, to enable the rotational arrangement of the spray pipes 120, the range hood 100 further includes a drive unit 160. The drive unit 160 and the spray pipes 120 are arranged in a one-to-one correspondence. The drive unit 160 is connected to the corresponding spray pipe 120 and drives the corresponding spray pipe 120 to rotate. Specifically, a support plate 111 is connected to the side wall of the body 110. There is a gap between the support plate 111 and the bottom of the body 110. The drive unit 160 can be a motor, arranged within this gap, and assembled to the inner bottom of the body 110. The bottom end of the spray pipe 120 rotatably passes through the support plate 111 and is connected to the output end of the corresponding drive unit 160. The top end of the spray pipe 120 is rotatably connected to the top of the body 110. When the drive unit 160 receives a command output, it drives the corresponding spray pipe 120 to rotate, so that cleaning consumables can be evenly sprayed into the interior of the body 110. To improve the smoothness of the rotation of the spray pipe 120, a copper sleeve or bearing can be provided between the bottom end of the spray pipe 120 and the support plate 111, and between the top end of the spray pipe 120 and the top of the machine body 110.

[0044] In another embodiment, only one drive unit 160 may be provided, which drives the rotation of both spray pipes 120. Specifically, the output end of the drive unit 160 is connected to one of the spray pipes 120, and a transmission component, such as a chain or belt, connects the output end of the drive unit 160 to the other spray pipe 120. When the drive unit 160 receives a command output, it drives the connected spray pipe 120 to rotate, simultaneously driving the transmission component to rotate, which in turn drives the other spray pipe 120 to rotate. Since only one drive unit 160 is needed to drive the rotation of both spray pipes 120, costs can be saved to some extent.

[0045] Combination Figure 1 as well as Figure 2 The top end of the spray pipe 120 passes through the top of the body 110, so that the end of the spray pipe 120 serves as the water inlet. A first heater 130 is arranged on the top of the body 110 and positioned between the two spray pipes 120. The first heater 130 has two output sections. One output section of the first heater 130 is connected to the water inlet of one of the spray pipes 120 via a pipe, and the other output section of the first heater 130 is connected to the water inlet of the other spray pipe 120 via a pipe. This arrangement saves piping and makes efficient use of the space in the body 110 while simultaneously supplying cleaning consumables to both spray pipes 120.

[0046] Combination Figure 1 as well as Figure 2The main body 110 is also equipped with a water inlet 170, which is connected to the first heating element via a pipe. The water inlet 170 and the first heater 130 can be arranged on the side of the main body 110 against the wall to avoid affecting the air intake of the range hood. In one embodiment, the water inlet 170 can be a connector. When the range hood needs to be cleaned, the user connects the water inlet 170 to a faucet and a storage device for cleaning consumables such as detergent via a pipe. The first heater 130 has a built-in pump. When the first heater 130 is working, it delivers at least one of the cleaning water and detergent to the water inlet 170, and then distributes it through the two spray pipes 120. In another embodiment, the water inlet 170 is a box structure with at least two storage chambers inside to facilitate the storage of cleaning water and detergent. When the inside of the range hood needs to be cleaned, the first heater 130 operates, delivering at least one of the cleaning water and detergent to the water inlet 170, and then distributing it through the first heater 130, spraying it out through the two spray pipes 120 respectively; when the cleaning consumables in the water inlet 170 are used up, the user can replenish the cleaning consumables in the water inlet 170.

[0047] Combination Figure 3 At least a portion of the spray pipe 120 is spiral-shaped, and spray holes 121 are evenly distributed along the pipe body, located on both flat and protruding sections. During the spraying of cleaning materials through the spray pipe 120, the spiral flow path of the materials within the pipe extends the mixing path when using two or more cleaning materials, resulting in more thorough mixing. This helps ensure uniform spraying, improving efficiency and effectiveness. Furthermore, the spiral arrangement of the spray pipe 120 maintains a more stable spraying effect even under unstable water pressure. This allows the cleaning materials to cover all parts of the inner wall of the oven cavity and provides a higher spray speed from the spray holes 121, enhancing the cleaning effect on the inner wall of the oven cavity and demonstrating excellent practicality.

[0048] Combination Figure 4In some embodiments, the spray pipe 120 is provided with two or more spray channels, and each spray channel is provided with a corresponding second heater 140. The second heater 140 can heat the cleaning consumables in the spray channel, thereby causing the spray pipe 120 to spray the heated cleaning consumables. Specifically, there are two spray channels, namely a first spray channel and a second spray channel. For example, if the cleaning consumables contain moisture, steam can be sprayed into the spray hole 121, and the steam can quickly remove the oil stains on the inside of the machine body 110, improving the cleaning effect; if the cleaning consumables contain detergent, the oil stains inside the machine body 110 can be softened, improving the cleaning effect. In addition, the heater can be a heating pipe, and a slit 124 is formed in the heating pipe and the corresponding spray channel. The cleaning consumables are stored in the slit 124. This arrangement can reduce the storage space of the cleaning consumables in the spray channel, thereby allowing the cleaning consumables to be sprayed at a higher speed, improving the cleaning effect on the inner wall of the inner liner.

[0049] Since there are two or more spray channels, the spray pipe 120 can simultaneously spray two or more cleaning consumables, or asynchronously spray two or more cleaning consumables, to achieve different spraying effects. In specific implementations, two spray channels are arranged side-by-side, and are defined as the first spray channel and the second spray channel, respectively. The first spray channel is used to store cleaning water, and the second spray channel is used to store cleaning consumables such as detergent. In another embodiment, there may be only one spray pipe 120 within the spray pipe 120; this application does not impose any restrictions on this.

[0050] It should be noted that "at least part of the spray pipe 120 is spiral" means that the entire body of the spray pipe 120 is spiral, or that the middle part of the spray pipe 120 is spiral and the two ends of the spray pipe 120 are columnar structures. This application does not limit this.

[0051] Figure 5 It shows Figure 3 A structural diagram from another perspective. Combined with... Figure 5 The end of the spray pipe 120 is provided with two or more spray connectors 125, and each spray connector 125 is connected to a corresponding spray channel. The two spray connectors 125 are integrated into one piece and can rotatably pass through the top of the body 110 to communicate with the first heater 130. The first heater 130 delivers cleaning consumables through the spray connectors 125 to the corresponding spray channels and outputs them from the spray holes 121 of the spray pipe 120.

[0052] Based on the above-described range hood 100, this disclosure also provides a method for cleaning the range hood 100. Figure 6 A flowchart illustrating the cleaning method for the range hood 100 is shown, combined with... Figure 6The cleaning method for the range hood 100 includes: confirming the oil concentration inside the body 110; if the oil concentration inside the body 110 is confirmed to be within a first preset value, controlling neither the first heater 130 nor the second heater 140 to start; if the oil concentration inside the body 110 is confirmed to be within a second preset value, controlling one of the first heater 130 and the second heater 140 to start; if the oil concentration inside the body 110 is confirmed to be between a second preset value and a third preset value, controlling both the first heater 130 and the second heater 140 to start, wherein the third preset value is greater than the second preset value, and the second preset value is greater than the first preset value.

[0053] The cleaning method for the range hood 100 provided in this disclosure can control the activation of either the first heater 130 or the second heater 140 according to the concentration of oil stains inside the body 110, thereby saving cleaning consumables and energy consumption while ensuring the cleaning effect inside the range hood, and has good practicality.

[0054] When the oil concentration inside the body 110 is confirmed to be within a first preset value, the range hood 100 is in a first cleaning mode. This first cleaning mode is suitable for cleaning scenarios where the oil level inside the range hood is relatively low. Specifically, the first heater 130 and the second heater 140 are both kept off. The pump of the first heater 130 delivers at least one of cleaning water and detergent to the spray pipe 120, and sprays it out from the spray holes 121 of the spray pipe 120 into the body 110 to clean the inside of the range hood. For example, in one embodiment, cleaning water is input into the first spray pipe 122 of the spray pipe 120, and the spray pipe 120 outputs cleaning water to clean the inside of the range hood; or, detergent is input into the second spray channel of the spray pipe 120, and the spray pipe 120 outputs detergent to clean the inside of the range hood; that is, only one type of cleaning consumable is used to clean the inside of the range hood. In another embodiment, the first spray pipe 122 of the spray pipe 120 is used to input cleaning water, and the second spray channel is used to input detergent. The spray pipe 120 simultaneously outputs detergent to clean the inside of the range hood, that is, two kinds of cleaning consumables are used to clean the inside of the range hood.

[0055] When the oil concentration inside the body 110 is confirmed to be within the second preset value, the range hood 100 enters the second cleaning mode. This second cleaning mode is suitable for cleaning scenarios where the inner wall of the liner is heavily soiled. Specifically, one of the first heater 130 and the second heater 140 is activated. The pump of the first heater 130 delivers at least one of cleaning water and detergent to the spray pipe 120, and sprays it out from the spray hole 121 of the spray pipe 120 into the interior of the body 110 to clean the inside of the range hood. For example, cleaning water is introduced into the first spray pipe 122 of the spray pipe 120, and detergent is introduced into the second spray channel. The cleaning water is heated to form steam, and the detergent is heated and sprayed out asynchronously through the spray hole 121. That is, the two cleaning consumables are sprayed out sequentially to clean the inside of the range hood. In one embodiment, steam is first sprayed out to soften the oil stains; then detergent is sprayed out to decompose the oil stains inside the machine body 110. During the decomposition of the oil stains, the fan 150 can be controlled to jog or continuously rotate at a low speed. Finally, steam is sprayed out again to rinse the decomposed oil stains. During the rinsing process, the fan 150 jogs or continuously rotates at a low speed, and detergent can also be pumped in intermittently or continuously for a period of time. Finally, the oil is dried by the high-speed fan 150. In another embodiment, detergent is first sprayed out to decompose the oil stains inside the machine body 110. During the decomposition of the oil stains, the fan 150 can be controlled to jog or continuously rotate at a low speed. Then, steam is sprayed out to rinse the decomposed oil stains. During the rinsing process, the fan 150 jogs or continuously rotates at a low speed, and detergent can also be pumped in intermittently or continuously for a period of time. Finally, the oil is dried by the high-speed fan 150.

[0056] When the oil concentration inside the unit 110 is confirmed to be within the third preset value, the range hood 100 enters the third cleaning mode. The third cleaning mode is suitable for cleaning scenarios with higher oil concentration inside the unit 110 compared to the second cleaning mode. Specifically: the first heater 130 and the second heater 140 are started simultaneously, and the pump of the first heater 130 is used to deliver cleaning water and detergent to the spray pipe 120 at the same time. The spray holes 121 of the spray pipe 120 spray out a mixture of steam and detergent to clean the inside of the unit. Finally, the steam is sprayed out to rinse the decomposed oil. During the rinsing process, the fan 150 rotates intermittently or continuously at a low speed, and can also pump detergent in intermittently or continuously for a period of time. Finally, the oil is dried by the high-speed fan 150.

[0057] It should be noted that different cleaning modes can be selected by the user. For example, the cleaning mode option can be set on the control panel of the range hood 100 or on the control terminal connected to the range hood 100, allowing the user to actively select the cleaning mode; or / and, the range hood 100 is equipped with an oil fume concentration detector, which can obtain the oil fume concentration inside the unit 110. When the user needs to clean the inside of the unit 110, the controller of the range hood 100 automatically selects a cleaning mode that matches the oil fume concentration based on the obtained oil fume concentration inside the unit 110; or, the range hood 100 determines the degree of oil accumulation based on the operating time of the range hood 100 and automatically selects a cleaning mode that matches the oil fume concentration. This application does not impose any limitations on this.
