Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of kitchen appliances, in particular to a range hood. Background Art
[0002] Currently, range hoods on the market usually adopt a single smoke inlet, which is generally designed in the middle of the bottom plate of the range hood. Although the range hood of this design can absorb most of the oil smoke entering the range hood cavity from the middle, because the range hood is usually hung at a higher position, the smoke collection range is not large enough, and there is no smoke inlet on the rear side of the range hood. Since the wall surface itself has a certain adsorption effect on the fluid, the oil smoke will escape from the wall surface and the surroundings due to the adsorption force of the wall. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a range hood in order to overcome the defect in the prior art that oil smoke escapes from the rear side of the range hood and is easily adsorbed by the wall.
[0004] The utility model solves the above technical problems through the following technical solutions:
[0005] The utility model provides a range hood, which comprises a range hood body and an oil receiving box;
[0006] The range hood body has a fixing plate and an air inlet plate, the range hood body is fixed to the wall through the fixing plate, the air inlet plate has a rear area close to the fixing plate, and the rear area is provided with a first air inlet;
[0007] The oil receiving box is connected to the range hood body and is located below the first air inlet. The orthographic projection of the first air inlet is located within the range of the oil receiving box. There is a gap between the oil receiving box and the first air inlet for oil smoke to pass through.
[0008] In the present solution, the range hood is fixed to the wall by a fixing plate, and the air inlet plate is provided with a first air inlet in the rear area near the fixing plate. Therefore, the first air inlet is close to the wall where the fixing plate is located, and oil smoke can be sucked into the range hood through the first air inlet, thereby improving the suction capacity of the rear side of the range hood and preventing oil smoke from escaping from the wall surface and the surroundings due to the adsorption force of the wall. The oil droplets condensed by the sucked oil smoke can drip into the oil receiving box provided below the first air inlet, and the orthographic projection of the first air inlet is located within the range of the oil receiving box, thereby ensuring that the oil droplets can completely drip into the oil receiving box. There is a gap between the oil receiving box and the first air inlet for oil smoke to pass through, thereby preventing the oil receiving box from blocking the air inlet path of the first air inlet and affecting the suction effect of the first air inlet.
[0009] Preferably, the range hood comprises a blocking member, which is provided on the air inlet plate and located between the first air inlet and the fixed plate, and the orthographic projection of the blocking member is located within the range of the oil receiving box.
[0010] In the present embodiment, the range hood is provided with a blocking member located between the first air inlet and the fixed plate, the blocking member can prevent the oil smoke from being absorbed by the wall, the blocking member can guide the oil droplets formed by the condensation of the oil smoke, and the orthographic projection of the blocking member is located within the range of the oil collecting box, so that the oil droplets can drip into the oil collecting box along the blocking member, thereby preventing the oil droplets from contaminating the wall.
[0011] Preferably, the blocking member is arranged on a peripheral side of the first air inlet.
[0012] In this solution, by arranging the blocking member on the peripheral side of the first air inlet, it is easier for the oil droplets formed by the condensation of oil smoke to drip into the oil collecting box from the first air inlet, thereby better collecting the oil droplets.
[0013] Preferably, in the direction from the oil receiving box toward the first air inlet, the side plates of the oil receiving box that are arranged opposite to each other gradually extend in a direction away from each other.
[0014] In the present embodiment, the above-mentioned structural form is adopted, so that the distance between the side plates of the oil collecting box which are relatively arranged can be larger as they are closer to the first air inlet, thereby making it easier for the oil collecting box to collect oil droplets and prevent oil droplets from dripping outside the oil collecting box.
[0015] Preferably, in the width direction of the range hood, the air inlet plate extends obliquely upward from the fixing plate in a direction away from the fixing plate.
[0016] In the present scheme, the above-mentioned structural form is adopted, and the air inlet plate inclined upward from the fixed plate towards the direction away from the fixed plate can block the oil smoke, which is more conducive to the oil smoke gathering in the rear area of the air inlet plate. The gathered oil smoke is sucked into the first air inlet, making the range hood have a better smoke extraction effect.
[0017] Preferably, the air inlet plate further has a main smoke collecting area, the main smoke collecting area is provided with a groove sunken toward the interior of the range hood body, and a second air inlet is provided in the groove.
[0018] In this solution, the air inlet plate also has a main smoke collecting area, which is provided with a groove sunken into the interior of the range hood body, so that the smoke can gather in the groove, and the smoke collecting effect is better. The groove is provided with a second air inlet, which can absorb the smoke gathered in the groove, thereby improving the smoke extraction effect in the middle part of the range hood.
[0019] Preferably, both sides of the first air inlet and the second air inlet are aligned in the width direction of the range hood.
[0020] In this solution, by adopting the above-mentioned structural form, the first air inlet and the second air inlet can cooperate better, and the smoking effect is more symmetrical, thereby making the smoking effect of the range hood better.
[0021] Preferably, the rear area partially overlaps with the main smoke collecting area, and the first air inlet is arranged on one side of the top wall of the groove close to the fixing plate or on the first side wall of the groove close to the fixing plate;
[0022] Alternatively, the rear area does not overlap with the main smoke collecting area, and the first air inlet is arranged at a position outside the groove.
[0023] In the present embodiment, the first air inlet can be arranged in the groove or outside the groove. When the first air inlet is arranged in the groove, the first air inlet can be arranged on the side of the top wall of the groove close to the fixed plate, or can be arranged on the first side wall of the groove close to the fixed plate, both of which can achieve the effect of absorbing the oil smoke on the rear side of the range hood.
[0024] Preferably, the groove has two second side walls extending along the width direction of the range hood, and the two second side walls are both provided with a third air inlet.
[0025] In this solution, third air inlets are provided on the second side walls on both sides of the groove, so that oil smoke can be absorbed from both sides of the range hood, thereby improving the smoke extraction effect of the range hood.
[0026] Preferably, the groove has a front portion away from the fixing plate, and the second air inlet is arranged at the front portion.
[0027] In this solution, the second air inlet is arranged at the front part of the groove, which is more conducive to absorbing the oil smoke at the front side of the range hood, and together with the first air inlet in the rear area and the third air inlet on both sides of the groove, a fully enclosed suction effect is formed. On the other hand, a natural invisible wind curtain can be formed at the front part, which isolates the oil smoke from the user, can effectively prevent the oil smoke from escaping from the front, and ensure the oil smoke suction effect.
[0028] The positive and progressive effects of the utility model are:
[0029] The range hood of the utility model is fixed to the wall by a fixing plate, and the air inlet plate is provided with a first air inlet in the rear area close to the fixing plate. Therefore, the first air inlet is close to the wall where the fixing plate is located, and oil smoke can be sucked into the range hood through the first air inlet, thereby improving the suction capacity of the range hood at the rear side and preventing oil smoke from escaping from the wall surface and the surroundings due to the adsorption force of the wall. Oil droplets condensed by the sucked oil smoke can drip into the oil receiving box arranged below the first air inlet, and the orthographic projection of the first air inlet is located within the range of the oil receiving box, thereby ensuring that the oil droplets can completely drip into the oil receiving box. There is a gap between the oil receiving box and the first air inlet for oil smoke to pass through, thereby preventing the oil receiving box from blocking the air inlet path of the first air inlet and affecting the suction effect of the first air inlet.

[0054] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.
[0055] Example 1
[0056] like Figure 1 and Figure 2 As shown, this embodiment provides a range hood 100, which includes a range hood body 110 and an oil receiving box 400. The range hood body 110 has a fixing plate 200 and an air inlet plate 300, the range hood body 110 is fixed to the wall through the fixing plate 200, the air inlet plate 300 has a rear area 310 close to the fixing plate 200, and the rear area 310 is provided with a first air inlet 311. The oil receiving box 400 is connected to the range hood body 110 and is located below the first air inlet 311, the orthographic projection of the first air inlet 311 is located within the range of the oil receiving box 400, and there is a gap between the oil receiving box 400 and the first air inlet 311 for oil smoke to pass through.
[0057] The range hood 100 is fixed to the wall through the fixing plate 200, and the air inlet plate 300 is provided with a first air inlet 311 in the rear area 310 close to the fixing plate 200. Therefore, the first air inlet 311 is close to the wall where the fixing plate 200 is located, and the oil smoke can be sucked into the range hood 100 through the first air inlet 311, thereby improving the suction capacity of the rear side of the range hood 100, preventing the oil smoke from escaping from the wall surface and the surroundings due to the adsorption force of the wall, and the sucked oil smoke is sucked into the range hood 100. The oil droplets formed by the condensation of smoke can drip into the oil receiving box 400 arranged below the first air inlet 311. The orthographic projection of the first air inlet 311 is located within the range of the oil receiving box 400, thereby ensuring that the oil droplets can completely drip into the oil receiving box 400. There is a gap between the oil receiving box 400 and the first air inlet 311 for the oil smoke to pass through, thereby preventing the oil receiving box 400 from blocking the air inlet path of the first air inlet 311 and affecting the smoking effect of the first air inlet 311.
[0058] In this embodiment, the number of first air inlets 311 is two and they are arranged in parallel and spaced apart. In other embodiments, the number of first air inlets 311 may be one or more, and other numbers and arrangements of first air inlets 311 deemed appropriate by those skilled in the art may also be selected.
[0059] like Figure 3 As shown, the range hood 100 includes a blocking member 500, which is arranged on the air inlet plate 300 and is located between the first air inlet 311 and the fixed plate 200. The blocking member 500 can prevent the oil smoke from being absorbed by the wall. The blocking member 500 can guide the oil droplets formed by the condensation of the oil smoke. The orthographic projection of the blocking member 500 is located within the range of the oil receiving box 400, so that the oil droplets can drip into the oil receiving box 400 along the blocking member 500 to prevent the oil droplets from contaminating the wall.
[0060] The blocking member 500 is disposed on the peripheral side of the first air inlet 311, so that it is easier for oil droplets formed by condensation of oil smoke to drip from the first air inlet 311 into the oil receiving box 400, and the oil droplets can be better collected.
[0061] like Figure 4 As shown, in this embodiment, in the direction of the oil receiving box 400 toward the first air inlet 311, the side plates 410 of the oil receiving box 400 that are relatively arranged gradually extend in the direction away from each other, so that the distance between the side plates 410 of the oil receiving box 400 that are relatively arranged can be larger at the position closer to the first air inlet 311, thereby being more conducive to the oil receiving box 400 collecting oil droplets and preventing the oil droplets from dripping outside the oil receiving box 400. In other embodiments, the side plates 410 of the oil receiving box 400 that are relatively arranged can also be arranged in parallel, or other side plate 410 arrangement methods that are deemed appropriate by those skilled in the art can be selected.
[0062] like Figure 1 As shown, in the width direction x of the range hood 100, the air inlet plate 300 extends obliquely upward from the fixing plate 200 to a direction away from the fixing plate 200. The width direction x refers to the direction in which the range hood 100 is perpendicular to the fixing surface. The air inlet plate 300 extending obliquely upward from the fixing plate 200 to a direction away from the fixing plate 200 can block the oil smoke, and is more conducive to the oil smoke gathering in the rear area 310 of the air inlet plate 300. The gathered oil smoke is sucked into the first air inlet 311, so that the range hood 100 has a better smoke extraction effect.
[0063] The air inlet plate 300 also has a main smoke collecting area 600, which is provided with a groove 320 that is recessed toward the inside of the range hood body 110, so that the oil smoke can be gathered in the groove 320, and the smoke collecting effect is better. In this embodiment, the side wall of the groove 320 is inclined from bottom to top toward the center of the range hood body 110. In other embodiments, the side wall of the groove 320 can be vertically arranged, or can be inclined from bottom to top toward the outside of the range hood body 110. The groove 320 is provided with a second air inlet 321, which can absorb the oil smoke gathered in the groove 320, and improve the smoke collection effect of the middle part of the range hood 100.
[0064] In this embodiment, the first air inlet 311 and the second air inlet 321 are aligned on both sides in the width direction x of the range hood 100, so that the first air inlet 311 and the second air inlet 321 can cooperate better and the smoke extraction effect is more symmetrical, thereby making the smoke extraction effect of the range hood 100 better. In other embodiments, the first air inlet 311 and the second air inlet 321 may not be aligned on both sides in the width direction x of the range hood 100.
[0065] The groove 320 has two second side walls 323 extending along the width direction x of the range hood 100 , and the two second side walls 323 are each provided with a third air inlet 324 .
[0066] In this embodiment, the second side walls 323 on both sides of the groove 320 are provided with third air inlets 324, so that oil smoke can be absorbed from both sides of the range hood 100, so that the range hood 100 has a better smoke extraction effect. In other embodiments, the third air inlets 324 can also be arranged on both sides of the groove 320 close to the second side walls 323, and other locations of the third air inlets 324 that are considered appropriate by those skilled in the art can also be selected.
[0067] In this embodiment, the groove 320 has a front part 325 away from the fixing plate 200, and the second air inlet 321 is arranged at the front part 325, which is more conducive to absorbing the oil smoke on the front side of the range hood 100, and together with the first air inlet 311 of the rear area 310 and the third air inlet 324 on both sides of the groove 320, a fully enclosed smoking effect is formed. On the other hand, a natural invisible wind curtain can be formed at the front part, which isolates the oil smoke from the user, can effectively prevent the oil smoke from escaping from the front, and ensure the oil smoke absorbing effect. In other embodiments, the second air inlet 321 can also be arranged in the middle of the groove 320, and other positions for setting the second air inlet 321 that are deemed appropriate by those skilled in the art can also be selected.
[0068] like Figure 2As shown, in this embodiment, the rear area 310 does not overlap with the main smoke collecting area 600, and the first air inlet 311 is arranged outside the groove 320, so that the oil smoke that is not sucked into the groove 320 or the oil smoke that escapes from the groove 320 can be absorbed by the first air inlet 311, which is beneficial to further improve the smoke extraction capacity of the rear side of the range hood 100.

[0071] like Figure 5 As shown, in this embodiment, the rear area 310 partially overlaps with the main smoke collecting area 600, and the first air inlet 311 is provided in the first side wall 322 of the groove 320 close to the fixing plate 200. With this structural form, the effect of improving the smoke extraction capacity of the rear side of the range hood 100 can also be achieved, and the smoke can be prevented from escaping from the wall surface and the surroundings due to the adsorption force of the wall.
