[0030] The utility model provides a range hood 100 .

[0031] See also Figures 1 to 6 In one embodiment of the present invention, the range hood 100 comprises:

[0032] The outer shell 1 includes a smoke collecting hood 3, the bottom of the smoke collecting hood 3 is provided with an oil collecting pan 31, and the bottom of the oil collecting pan 31 is installed with an oil cup 4 and a water cup 5. The part of the oil collecting pan 31 facing the oil cup 4 is provided with an oil hole 32 connected to the oil cup 4, so that the oil cup 4 receives the oil droplets from the oil collecting pan 31, and the water cup 5 is used to supply water to the cleaning device of the range hood 100.

[0033] Specifically, the range hood 100 mainly includes a fume hood 3, a chassis, a filter, a fume suction channel 11, a fan system and other components. The fan system is arranged in the chassis. When the range hood 100 is working, the fan rotates at a high speed inside the range hood 100, so that there is a certain pressure difference inside and outside the range hood 100, so that the air outside the range hood 100 flows into the range hood 100 through the fume suction channel 11, and the fume generated when cooking food is discharged. Therefore, the smoke hood 3 is provided with an air inlet, and a smoke suction channel 11 is provided in the shell 1 of the range hood 100. The air inlet end of the smoke suction channel 11 is connected to the air inlet, and the air outlet end is connected to the fan system. In order to adapt to the layout of the left and right double stoves in the kitchen, the range hood 100 is usually configured as a double-duct range hood 100, that is, two air inlets are provided on the air guide plate of the smoke hood 3, temporarily set as the left air inlet and the right air inlet. The diversion structure 2 is usually arranged on the inner side of the air guide plate and between the left air inlet and the right air inlet. The diversion structure 2 divides the smoke suction channel 11 into a left channel 111 and a right channel 112, so the diversion structure 2 is usually arranged below the fan system.

[0034] When the range hood 100 is in operation, oil droplets will flow down along the housing 1 from the fan system, so an oil collecting pan 31 is provided at the bottom of the fume collecting hood 3. The oil collecting pan 31 is used to collect the oil droplets dripping from the range hood 100, and in order to conveniently and timely discharge the oil droplets, an oil cup 4 is installed at the bottom of the oil collecting pan 31, and an oil hole 32 connected to the oil cup 4 is provided at the portion of the oil collecting pan 31 facing the oil cup 4, so that the oil cup 4 receives the oil droplets from the oil collecting pan 31. The oil droplets flow down along the housing 1 from the fan system into the oil collecting pan 31, and then flow to the oil hole 32, and flow into the oil cup 4 through the oil hole 32, thereby effectively guiding the oil droplets into the oil cup 4, and only the portion of the oil collecting pan 31 facing the oil cup 4 is connected to the oil hole 32 of the oil cup 4, which can effectively reduce the contact area between the cup mouth of the oil cup 4 and the fume suction channel 11, and reduce the possibility of re-evaporation of the oil droplets. A water cup 5 is also installed at the bottom of the oil collecting pan 31, and the water cup 5 can store clean water, so that the user does not need to provide clean water before each cleaning, and only needs to regularly add clean water to the water cup 5, thereby facilitating the automatic cleaning of the range hood 100. In addition, after the cleaning device cleans, it flows downward along the housing 1 to the oil collecting pan 31, then flows to the oil hole 32, and flows into the oil cup 4 through the oil hole 32, further facilitating the automatic cleaning of the range hood 100.

[0035] In this embodiment, the water cup 5 and the oil cup 4 are jointly arranged at the bottom of the oil collecting tray 31. Compared with being arranged on the side or inside of the smoke collecting hood 3, it is helpful to conveniently supply water to the cleaning device and also convenient for the user to replenish water in the water cup 5 in time.

[0036] The bottom of the smoke collecting hood 3 is usually configured as a strip whose width is much larger than its thickness. Figure 1 , Figure 2 and Figure 5 The width of the smoke hood 3 is the size of the smoke hood 3 along the left-right direction, and the thickness of the smoke hood 3 is the size of the smoke hood 3 along the front-back direction. The oil cup 4 and the water cup 5 are also usually configured as long strip groove cups to fit the shape of the bottom of the smoke hood 3.

[0037] The oil cup 4 can be detachably mounted on the oil collecting pan 31, so as to facilitate cleaning by the user. In this embodiment, two first slots are arranged at intervals on one side of the oil collecting portion facing the oil cup 4, and first flanges are arranged on two opposite edges of the cup opening of the oil cup 4, corresponding to the first flanges, which are clamped in the first slots. The first flanges are arranged on the opposite sides of the oil cup 4 along the left and right directions of the smoke collecting hood 3, that is, the shorter sides of the cup opening of the oil cup 4. The first slot has an opening that runs through the front and back. The oil cup 4 slides backward relative to the oil collecting pan 31 to clamp the first flange into the first slot to install the oil cup 4. The oil cup 4 slides forward relative to the oil collecting pan 31 to disengage the first flange from the first slot to remove the oil cup 4.

[0038] The water cup 5 can be detachably mounted on the oil collecting pan 31, so as to facilitate the user to clean it. In this embodiment, two second slots are arranged at intervals on one side of the oil collecting part facing the water cup 5, and second flanges are arranged at two opposite edges of the cup opening of the water cup 5, and the second flanges are clamped in the second slots. The second flanges are arranged on the opposite sides of the water cup 5 along the left and right directions of the smoke collecting hood 3, that is, the shorter sides of the cup opening of the water cup 5. The second slot has an opening that runs through the front and back. The water cup 5 slides backward relative to the oil collecting pan 31 to clamp the second flange into the second slot to install the water cup 5. The water cup 5 slides forward relative to the oil collecting pan 31 to disengage the second flange from the second slot to remove the water cup 5.

[0039] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 5 , along the length direction of the oil collecting pan 31, the oil collecting pan 31 includes a first oil collecting section 33 and a second oil collecting section 34 arranged in sequence, the oil cup 4 is arranged at the bottom of the first oil collecting section 33, the oil through hole 32 is opened in the first oil collecting section 33, and the water cup 5 is arranged at the bottom of the second oil collecting section 34. Specifically, the length direction of the oil collecting pan 31 is parallel to the left and right direction of the smoke collecting hood 3, the first oil collecting section 33 and the second oil collecting section 34 are arranged along the length direction of the oil collecting pan 31, thereby dividing the oil collecting pan 31 into two sections, and the first oil collecting section 33 is opened with an oil through hole 32, so as to facilitate the connection with the oil cup 4. The second oil collecting section 34 is sealed relative to the water cup 5, and guides the oil droplets dripping on the second oil collecting section 34 to the first oil collecting section 33, and then flows into the oil cup 4 through the oil through hole 32, thereby reducing the possibility of water in the water cup 5 being contaminated.

[0040] To further facilitate the guidance of the oil collecting pan 31, in the embodiment of the utility model, the depth of the oil collecting pan 31 is increased in the direction close to the first oil collecting section 33. Specifically, the depth of the oil collecting pan 31 gradually increases in the direction close to the first oil collecting section 33, that is, the bottom surface of the oil collecting pan 31 is configured to be inclined or stepped or arc-shaped, so that the oil droplets flow to the oil holes 32, reducing the possibility of oil droplets accumulating in the oil collecting pan 31.

[0041] In other embodiments, the depth of the oil collecting pan 31 in the second oil collecting section 34 is less than the depth of the oil collecting pan 31 in the first oil collecting section 33 .

[0042] In order to facilitate the oil droplets to pass through the oil hole 32, in the embodiment of the utility model, please refer to Figures 2 to 6 The oil collecting pan 31 is provided with a plurality of oil holes 32 arranged at intervals. That is, the oil holes 32 are configured as a plurality of small holes arranged at intervals, so that it is convenient for oil droplets to pass through the oil holes 32 and the possibility of re-evaporation of oil droplets can be reduced.

[0043] Furthermore, the inner periphery of the oil hole 32 is provided with an oil guide flange 321 extending toward the oil cup 4. The oil guide flange 321 extends toward the inside of the oil cup 4, thereby guiding the oil droplets to flow to the oil cup 4, facilitating the oil droplets to pass through the oil hole 32, and on the other hand, reducing the distance from the oil collecting pan 31 to the bottom of the oil cup 4, reducing the possibility of oil droplets splashing, and facilitating subsequent cleaning by users.

[0044] The oil guiding flange 321 is integrally formed with the oil collecting pan 31 , that is, the oil guiding flange 321 is formed by stamping the inner periphery of the oil hole 32 .

[0045] See also Figure 2 and Figure 4 In the embodiment of the utility model, the range hood 100 further includes a water guide pipe 6, and the oil collecting pan 31 is provided with a first mounting boss 35 protruding inwardly, and a through hole for the water guide pipe 6 to pass through is opened on the first mounting boss 35, and the first mounting boss 35 is located at an end of the oil collecting pan 31 away from the oil cup 4. Specifically, the water guide pipe 6 extends toward the cleaning device to supply water to the cleaning device, so one end of the water guide pipe 6 extends into the water cup 5, and the other end passes through the oil collecting pan 31 and extends toward the cleaning device, so a through hole needs to be provided at the bottom of the oil collecting pan 31. In order to reduce the possibility of oil droplets infiltrating into the water cup 5 from the through hole, the oil collecting pan 31 is provided with a first mounting boss 35 protruding inwardly, so that the height of the first mounting boss 35 is higher than the height of the collecting pan, and the through hole is opened at the first mounting boss 35, thereby reducing the possibility of oil droplets infiltrating into the water cup 5 from the through hole. Furthermore, because the water conduit 6 extends upward, in order to facilitate the arrangement of the water conduit 6 , the first mounting boss 35 is located at an end of the oil collecting pan 31 away from the oil cup 4 .

[0046] In order to fully utilize the clean water in the water cup 5 , one end of the water pipe 6 is plugged into the bottom of the water cup 5 .

[0047] Please refer again Figure 2 and Figure 4 In the embodiment of the utility model, the smoke hood 3 includes a smoke hood 3 body, and a guide plate 36 covering the front side of the smoke hood 3 body, and the smoke hood 3 body includes a bottom plate 38 and a back plate 37, an oil collecting pan 31 is arranged on the bottom plate 38, and the bottom edge of the guide plate 36 is installed on the side of the bottom plate 38 away from the back plate 37. Specifically, the smoke hood 3 body is the main part of the smoke hood 3, and the front side of the smoke hood 3 body is provided with an opening, the guide plate 36 covers the opening, and the guide plate 36 is provided with an air inlet. The smoke hood 3 body includes a bottom plate 38 and a back plate 37, the back plate 37 is used to be installed on the wall, the bottom plate 38 is provided with an oil collecting pan 31, and the bottom edge of the guide plate 36 is installed on the side of the bottom plate 38 away from the back plate 37. Among them, the bottom plate 38 and the back plate 37 are integrally formed, so as to facilitate the assembly of the smoke hood 3 and reduce the possibility of oil leakage.

[0048] Further, the side of the bottom plate 38 away from the back plate 37 is provided with a mounting flange 381 extending toward the guide plate 36, and the mounting flange 381 is coated on the side of the guide plate 36 away from the back plate 37. Specifically, the mounting flange 381 is coated on the side of the guide plate 36 away from the back plate 37, thereby further reducing the possibility of oil leakage.

[0049] Furthermore, the oil hole 32 is opened on the side of the bottom plate 38 close to the back plate 37, and the depth of the oil collecting pan 31 increases in the direction away from the guide plate 36. Because the bottom edge of the guide plate 36 is installed on the side of the bottom plate 38 away from the back plate 37, the oil hole 32 is opened on the side of the bottom plate 38 close to the back plate 37, that is, the oil hole 32 is opened on the side of the bottom plate 38 away from the guide plate 36, and the depth of the oil collecting pan 31 increases in the direction away from the guide plate 36, thereby further guiding the oil droplets left along the guide plate 36, and further facilitating the oil droplets to flow into the oil cup 4.

[0050] In another embodiment of the utility model, the oil collecting pan 31 is further provided with a second mounting boss 39 protruding inwardly, and the guide plate 36 is mounted on the second mounting boss 39. Since the bottom edge of the guide plate 36 is mounted on the side of the bottom plate 38 away from the back plate 37, a mounting structure needs to be provided between the guide plate 36 and the bottom plate 38, such as the guide plate 36 and the bottom plate 38 are connected by fasteners. At this time, in order to reduce the leakage of oil droplets from between the guide plate 36 and the bottom plate 38, the oil collecting pan 31 is further provided with a second mounting boss 39 protruding inwardly, so that the height of the second mounting boss 39 is higher than the height of the collecting pan, and the through hole is opened in the second mounting boss 39, thereby reducing the possibility of oil leakage from the installation gap between the guide plate 36 and the bottom plate 38.
