Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a fume hood and a range hood. Background Art

[0002] Range hoods have become one of the indispensable kitchen appliances in people's daily lives. Range hoods can quickly remove the fumes generated during the user's cooking process, reduce pollution, purify the air, and greatly improve people's quality of life.

[0003] A range hood usually includes a smoke hood, and an oil cup is usually provided at the bottom of the smoke hood. An air inlet may be provided on the front panel of the smoke hood. External smoke can enter the range hood through the air inlet along with the air flow, and be discharged to the outside under the action of the volute. A part of the smoke passing through the interior of the range hood may form oil and remain inside the range hood. The oil slides to the bottom of the smoke hood, and finally flows to the oil cup and is collected in the oil cup. However, the irregular sliding of the oil to the bottom of the smoke hood will cause a large area of ​​oil contamination inside the range hood, and the oil may drip along the front panel to the air inlet. In order to improve the efficiency of extracting smoke, the air inlet is usually set in the middle area of ​​the bottom of the front panel, and the air inlet is usually set facing the user. The presence of oil dripping at the air inlet will greatly affect the user experience. Utility Model Content

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the utility model, a smoke collecting hood is provided. The smoke collecting hood includes a front panel, a rear panel and two side panels, the front panel, the rear panel and the two side panels enclose a chamber with a top opening, the top opening has an opening front side corresponding to the front panel, the smoke collecting hood also includes an oil guide member extending from the outside of the chamber through the opening front side into the chamber, the portion of the oil guide member in the chamber includes a main body and a receiving portion, the main body is parallel to the front panel and has a connecting end, the receiving portion is connected to the connecting end and forms an oil guide groove between the main body and the receiving portion to guide the oil to the direction of the two side panels.

[0005] The utility model provides a smoke hood, in which the oil guide groove can guide the oil in the smoke hood toward the two side panels, so that after the oil in the smoke hood flows to the oil guide groove, it will slide to the vicinity of the side panels under the guidance of the oil guide groove. Only after the oil reaches the vicinity of the side panels will it continue to slide toward the bottom of the smoke hood, and finally reach the oil cups on both sides of the bottom of the smoke hood. In such a smoke hood, the oil slides downward toward the oil cups in a relatively hidden position near the side panels, and the range of the smoke hood contaminated by the oil is relatively small. In addition, the middle area of ​​the front panel where the air inlet is arranged will not have oil dripping, which improves the user experience and prevents the collected oil from leaking out and polluting the kitchen environment.

[0006] Exemplarily, the oil guide groove includes a symmetrical first oil guide section and a second oil guide section, and the first oil guide section and the second oil guide section respectively guide the oil to one of the two side panels. Such an oil guide groove structure is more regular and easy to produce, and the oil slides in such an oil guide groove in the direction of the two side panels, and the amount of oil that finally reaches the vicinity of the two side panels is similar, and there will not be a situation where one side has less oil and is easy to clean, while the other side has more oil and is difficult to clean and easy to clog.

[0007] For example, a free end is formed on one end of the receiving portion away from the connecting end, and the free end is higher than the connecting end. Such a receiving portion is easier to collect dripping oil and oil sliding off the oil guide member, and such a receiving portion can gather the oil collected in the oil guide groove to the bottom of the groove, and the oil will be more difficult to fall off the oil guide groove at other positions other than the two sides of the oil guide groove, thereby improving the guiding effect of the oil guide groove on the oil.

[0008] For example, a free end is formed on one end of the receiving portion away from the connecting end, and an upward flange is provided on the free end. The flange provided on the free end can limit the oil collected in the oil guide groove to prevent the oil from falling out of the oil guide groove, thereby ensuring that the oil slides out from both sides of the oil guide groove only when it reaches the vicinity of the two side panels under the guidance of the oil guide groove.

[0009] Exemplarily, the receiving portion is connected to a folding portion, and a free end is formed on one end of the receiving portion away from the connecting end, and the folding portion folds back from the free end toward the connecting end. The folding portion can limit the oil collected in the oil guide groove to prevent the oil from falling out of the oil guide groove, thereby ensuring that the oil will not slide out from both sides of the oil guide groove until it reaches the vicinity of the two side panels under the guidance of the oil guide groove. In addition, since there can be an overlapping portion between the portion of the receiving portion between the free end and the connecting end and the folding portion, the strength of such a receiving portion is obviously better. Moreover, the folding portion can be formed by folding the free end toward the connecting end, and the production of such a receiving portion is also simpler and more convenient.

[0010] Exemplarily, the receiving portion is connected to the connecting end by a rounded corner to form the bottom of the oil guide groove. The receiving portion is connected to the connecting end by a rounded corner. Compared with the connection between the receiving portion and the connecting end being an acute-angled cross-section, the rounded corner connection can reduce the influence caused by stress concentration, and the connection of the receiving portion to the connecting end by a rounded corner can be achieved by folding the oil guide piece. After folding to form the receiving portion, the folded portion is the connecting end. Such an oil guide piece has a simpler structure and is easy to produce. The receiving portion is connected to the connecting end by a rounded corner, and the oil guide groove can have an arc-shaped groove bottom. In such an oil guide groove, the oil is not easy to be retained or blocked at the groove bottom, and the oil is guided by the oil guide groove to slide in the direction of the two side panels for a better effect.

[0011] Exemplarily, two oil baffles are provided in the chamber, and the two oil baffles correspond to the two side panels respectively. An oil guide cavity is formed between the oil baffles and the corresponding side panels, and both sides of the receiving portion at least partially extend into the oil guide cavity. In such a smoke hood, the oil guide cavity and the oil guide groove cooperate, and the oil collected by the oil guide groove eventually enters the oil guide cavity, and slides through the oil guide cavity to the bottom of the smoke hood and is collected by the oil cup. In this way, the movement path of the oil inside the smoke hood is mostly in the oil guide groove and the oil guide cavity, and the oil guide cavity is located on both sides of the smoke hood. The overall movement path of the oil is relatively concealed, and there will be no oil dripping at the position similar to the air inlet on the middle area of ​​the front panel, so that the user experience is better. Moreover, when cleaning the smoke hood in this way, the cleaning can be more targeted and the cleaning efficiency is higher.

[0012] For example, the oil guide is fixedly connected to the side panel, and the main body is attached to the front panel. In this way, the overall structure of the smoke hood is simpler and more stable.

[0013] According to another aspect of the present invention, a range hood is provided. The range hood comprises a chassis and any of the above-described fume hoods, wherein the chassis is connected to the fume hood and is located above the fume hood. Such a range hood has a smaller range of oil contamination inside, and the overall equipment is easier to clean.

[0014] Exemplarily, the portion of the oil guide member outside the chamber is connected to the chassis. Connecting the portion of the oil guide member outside the chamber to the chassis can make the position of the chassis more stable, thereby improving the stability of the overall device.

[0015] For example, a housing cavity is formed in the case, a volute is provided in the housing cavity, an oil leakage port is provided on the volute, and the portion of the oil guide outside the cavity has an arc section away from the case, and the oil in the volute drips from the oil leakage port through the arc section to the receiving portion. Such a range hood has a higher efficiency in collecting the internal oil, and the overall cleaning of the equipment is simpler, further improving the user experience.

[0016] A series of simplified concepts are introduced in the utility model content, which will be further described in detail in the detailed implementation section. The utility model content section does not mean to attempt to define the key features and essential technical features of the technical solution claimed for protection, nor does it mean to attempt to determine the scope of protection of the technical solution claimed for protection.

[0026] In the following description, a large number of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only illustrates preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.

[0027] According to one aspect of the present invention, see Figure 1 and Figure 2 , a fume hood 10 is provided, and the fume hood 10 can be applied to any suitable equipment, including but not limited to a range hood. Therefore, according to another aspect of the present invention, a range hood is provided. The range hood may include a chassis 20 and a fume hood 10, and the chassis 20 may be connected to the fume hood 10 and may be located above the fume hood 10. The fume hood 10 and the range hood provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] See also Figure 1 and Figure 2The smoke hood 10 may include a front panel 11, a rear panel 12 and two side panels 13. The front panel 11, the rear panel 12 and the two side panels 13 may enclose a chamber 14 with a top opening, and the top opening may have an opening front side corresponding to the front panel 11. The heights of the side panels 13 and the rear panel 12 may both be greater than the height of the front panel 11, so that the top opening may be located above the front panel 11. The smoke hood 10 may also include an oil guide 100 extending from the outside of the chamber 14 through the front side of the opening to the inside of the chamber 14. The portion of the oil guide 100 located outside the chamber 14 may be located above the front panel 11, and the oil guide 100 may shield the front side of the opening.

[0029] See also Figure 3 , Figure 4 and Figure 5 The portion of the oil guide member 100 in the chamber 14 may include a main body 110 and a receiving portion 120. The main body 110 may be parallel to the front panel 11 and may have a connecting end 111. The receiving portion 120 may be connected to the connecting end 111 and may form an oil guide groove 130 with the main body 110 to guide the oil to the direction of the two side panels 13. The main body 110 may be close to the front panel 11, and the connecting end 111 may be considered as the end of the main body 110 extending into the chamber 14. The receiving portion 120 may be formed integrally with the connecting end 111, for example, the receiving portion 120 may be formed by folding a part of the oil guide member 100, and the folded portion forms the connecting end 111; the receiving portion 120 and the connecting end 111 may also be separately processed and connected together by welding, clamping or threaded connection. The oil guide groove 130 formed between the receiving portion 120 and the main body 110 may open upward and the opening direction may be at a certain angle to the horizontal plane. The guiding function in the oil guide groove 130 may be formed by the slope between the two sides of the oil guide groove 130 close to the two side panels 13. For example, the oil guide groove 130 may be a linear groove as a whole, and the lowest point of the linear groove may be formed near one of the two side panels 13. The oil guide groove 130 may also have a middle section with a higher height. Such an oil guide groove 130 may form a slope from the middle to the two sides, and thus the oil may be guided to one of the directions of the two side panels 13 according to the specific location of the oil. When such a smoke hood 10 is in use, the oil will first drip onto the oil guide member 100, and then the oil will slide on the oil guide member 100 to the connecting end 111 of the main body 110. The oil will be limited by the receiving part 120 and collected in the oil guide groove 130. Then, the oil will be guided by the oil guide groove 130 and slide in the direction of one of the two side panels 13.

[0030] The smoke hood 10 provided by the utility model can guide the oil guide groove 130 in the direction of the two side panels 13, so that after the oil inside the smoke hood 10 flows to the oil guide groove 130, it will slide to the vicinity of the side panels 13 under the guidance of the oil guide groove 130, and the oil will continue to slide toward the bottom of the smoke hood 10 after reaching the vicinity of the side panels 13, and finally reach the oil cups on both sides of the bottom of the smoke hood 10. In such a smoke hood 10, the oil slides downward to the oil cups at a relatively hidden position near the side panels 13, the range of the smoke hood 10 contaminated by the oil is relatively small, and the middle area of ​​the front panel 11 where the air inlet 17 is provided will not have oil dripping, which improves the user experience and prevents the collected oil from leaking out and polluting the kitchen environment.

[0031] In one embodiment of the present invention, see Figure 4 The oil guide groove 130 may include a symmetrical first oil guide section 131 and a second oil guide section 132. The first oil guide section 131 and the second oil guide section 132 may guide the oil to one of the directions of the two side panels 13. The connection point between the first oil guide section 131 and the second oil guide section 132 may be the highest point on the oil guide groove 130. Since the first oil guide section 131 and the second oil guide section 132 are symmetrical, the projections of the first oil guide section 131 and the second oil guide section 132 on the horizontal plane may have the same length, and the first oil guide section 131 and the second oil guide section 132 may have the same slope. Such an oil guide groove 130 has a more regular structure and is easy to produce. Moreover, the oil slides in such an oil guide groove 130 in the direction of the two side panels 13, and the amount of oil that finally reaches the vicinity of the two side panels 13 is similar, so there will not be a situation where the amount of oil on one side is small and easy to clean, while the amount of oil on the other side is large and difficult to clean and easy to clog.

[0032] In one embodiment of the present invention, see Figure 3 , Figure 4 and Figure 5 , a free end 121 may be formed on one end of the receiving portion 120 away from the connecting end 111, and the free end 121 may be higher than the connecting end 111. When the free end 121 is higher than the connecting end 111, it can be considered that the receiving portion 120 is tilted, there is an angle between the receiving portion 120 and the horizontal plane, and the receiving portion 120 is tilted upward. Such a receiving portion 120 is easier to collect dripping oil and oil sliding off the oil guide member 100, and such a receiving portion 120 can gather the oil collected in the oil guide groove 130 to the bottom of the groove, and the oil will be more difficult to fall off the oil guide groove 130 at other positions other than the two sides of the oil guide groove 130, thereby improving the guiding effect of the oil guide groove 130 on the oil.

[0033] The free end 121 may be provided with an upward flange. The flange may be designed in any suitable form according to actual needs. The free end 121 is provided with a flange to limit the oil collected in the oil guide groove 130, to prevent the oil from falling out of the oil guide groove 130, and to ensure that the oil will not slide out from both sides of the oil guide groove 130 until it reaches the vicinity of the two side panels 13 under the guidance of the oil guide groove 130.

[0034] Specifically, see Figure 3 , Figure 4 and Figure 5 , the receiving portion 120 may be connected with a folding portion 122, and the folding portion 122 may be folded back from the free end 121 toward the connecting end 111. The folding portion 122 is similar to the flange, and the folding portion 122 may also limit the oil collected in the oil guide groove 130 to prevent the oil from falling out of the oil guide groove 130, thereby ensuring that the oil will not slide out from both sides of the oil guide groove 130 until it reaches the vicinity of the two side panels 13 under the guidance of the oil guide groove 130. In addition, since there may be an overlapping portion between the portion of the receiving portion 120 between the free end 121 and the connecting end 111 and the folding portion 122, the strength of such a receiving portion 120 is obviously better. Moreover, the folding portion 122 can be formed by folding the free end 121 toward the connecting end 111, and the production of such a receiving portion 120 is also simpler and more convenient.

[0035] The receiving portion 120 can be connected to the connecting end 111 by rounding to form the bottom of the oil guide groove 130. The receiving portion 120 is connected to the connecting end 111 by rounding. Compared with the acute-angle cross section of the connection between the receiving portion 120 and the connecting end 111, the rounded connection can reduce the influence caused by stress concentration. Moreover, the rounded connection of the receiving portion 120 to the connecting end 111 can be achieved by folding the oil guide member 100. After folding to form the receiving portion 120, the folded portion is the connecting end 111. Such an oil guide member 100 has a simpler structure and is easy to produce. The receiving portion 120 is connected to the connecting end 111 by rounding, and the oil guide groove 130 can have an arc-shaped bottom. In such an oil guide groove 130, the oil is not easy to be retained or blocked at the bottom of the groove. The oil is guided by the oil guide groove 130 to slide in the direction of the two side panels 13 for a better effect.

[0036] Two oil baffles 15 may be provided in the chamber 14. The two oil baffles 15 may correspond to the two side panels 13 one by one. An oil guide cavity 16 may be formed between the oil baffles 15 and the corresponding side panels 13. The oil guide cavity 16 may be formed by the oil baffles 15, the front panel 11, the side panels 13 and the rear panel 12. Both sides of the receiving portion 120 may at least partially extend into the oil guide cavity 16. After the oil slides on the oil guide groove 130 to the part extending into the oil guide cavity 16, it may fall off the oil guide groove 130 and enter the oil guide cavity 16. After entering the oil guide cavity 16, the oil may slide down the front panel 11 to the bottom of the smoke hood 10, may directly drip to the bottom of the smoke hood 10, or may slide down the side panels 13 or the oil baffles 15 to the bottom of the smoke hood 10. The oil reaching the bottom of the smoke hood 10 may enter the oil cup. In such a smoke hood 10, the oil guide cavity 16 and the oil guide groove 130 cooperate, and the oil collected by the oil guide groove 130 eventually enters the oil guide cavity 16, and slides through the oil guide cavity 16 to the bottom of the smoke hood 10 and is collected by the oil cup. In this way, the movement path of the oil inside the smoke hood 10 is mostly in the oil guide groove 130 and the oil guide cavity 16, and the oil guide cavity 16 is located on both sides of the smoke hood 10. The overall movement path of the oil is relatively hidden, and there will be no oil dripping at the position similar to the air inlet 17 on the middle area of ​​the front panel 11, and the user experience is better. Moreover, when cleaning the smoke hood 10 in this way, the cleaning can be more targeted and the cleaning efficiency is higher.

[0037] See also Figure 2 , the oil guide member 100 can be fixedly connected to the side panel 13, and the main body 110 can be placed against the front panel 11. The rear panel 12 is usually used to be installed to the outside, and the side panel 13 can be fixedly connected to the rear panel 12. The oil guide member 100 is fixedly connected to the side panel 13 so that the position of the oil guide member 100 can be fixed, and the oil guide member 100 can stably block the front end of the opening of the chamber 14, thereby improving the stability of the overall device. The main body 110 being placed against the front panel 11 means that the main body 110 can be parallel to and fit the front panel 11. Since the position of the oil guide member 100 is fixed, the main body 110 is also stably fitted to the front panel 11, and the relative position of the main body 110 and the front panel 11 can be fixed without an additional connection structure, so that the overall structure of the smoke hood 10 is simpler and more stable.

[0038] According to another aspect of the present invention, a range hood is provided. Figure 1 and Figure 2The range hood may include a chassis 20 and any of the above-described fume hoods 10, and the chassis 20 may be connected to the fume hood 10 and may be located above the fume hood 10. Part of the oil in the chassis 20 may drip onto the oil guide 100, and then slide into the oil guide groove 130, and under the guidance of the oil guide groove 130, it reaches the vicinity of the two side panels 13 before sliding toward the bottom of the fume hood 10, and is finally collected by the oil cup at the bottom of the fume hood 10. Such a range hood has a smaller scope of oil contamination, and the overall equipment is easier to clean.

[0039] The portion of the oil guide member 100 outside the chamber 14 can be connected to the chassis 20. The portion of the oil guide member 100 outside the chamber 14 can include the portion of the oil guide member 100 located at the front end of the opening of the chamber 14. In fact, it can be considered that the portion of the oil guide member 100 outside the chamber 14 can be the portion of the oil guide member 100 that is higher than the front panel 11. The rear end surface of the chassis 20 can be fixedly connected to the rear panel 12, and the two side surfaces of the chassis 20 can be fixedly connected to the two side panels 13 through connecting plates. Since the portion of the oil guide member 100 outside the chamber 14 is located above the front panel 11, connecting the portion of the oil guide member 100 outside the chamber 14 to the chassis 20 can make the position of the chassis 20 more stable, thereby improving the stability of the overall device.

[0040] The housing 20 may be formed with a receiving cavity, a volute 21 may be provided in the receiving cavity, an oil leaking port 211 may be provided on the volute 21, and the portion of the oil guide 100 outside the chamber 14 may have an arc segment 140 away from the housing 20, and the oil in the volute 21 may drip from the oil leaking port 211 to the receiving portion 120 through the arc segment 140. The oil leaking port 211 may be the lowest opening on the volute 21, so that the oil at any position in the volute 21 can slide toward the oil leaking port 211. The volute 21 may be provided above the oil guide 100, specifically, the oil leaking port 211 of the volute 21 may be located above the arc segment 140, and the arc segment 140 may receive the oil dripping from the oil leaking port 211 and guide the oil to the oil guide groove 130. Such a range hood has a higher efficiency in collecting the internal oil, and the cleaning of the overall equipment is simpler, which further improves the user experience.
