Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to a range hood and its smoke collection chamber. Background Technology

[0002] Range hoods can quickly remove harmful fumes from stoves and cooking processes, expelling them outdoors and purifying the kitchen environment. They have been widely used.

[0003] Currently, because the range hood's smoke inlet is equipped with an oil mesh structure, when the smoke enters the smoke inlet, some of the smoke will condense on the outer surface of the oil mesh in the smoke collection chamber, forming oil droplets, which may then drip onto the user's stovetop.

[0004] In existing technologies, such as the utility model patent with patent number CN201922208224.2, multiple dripping holes are provided on the oil mesh body. Oil droplets formed on the inner side of the oil mesh body flow through the dripping holes to the smoke collection chamber and then into the oil cup, thereby preventing oil droplets from falling onto the user's stove. However, oil droplets formed by the condensation of smoke on the inner surface of the oil mesh may remain at the dripping holes, ultimately making it difficult for oil to pass through the dripping holes.

[0005] Therefore, there is an urgent need for a range hood and its smoke collection chamber to solve the above problems. Utility Model Content

[0006] One of the technical problems solved by this utility model is to provide a smoke collection chamber that can effectively solve the problem of difficulty in passing oil through the dripping hole in the prior art.

[0007] The second technical problem solved by this utility model is to provide a range hood that can effectively solve the problem of oil leakage through the drip hole in the prior art.

[0008] The first technical problem mentioned above is solved by the following technical solution:

[0009] A range hood's smoke collection chamber includes a smoke inlet plate, the smoke inlet plate including an inclined mounting plate and an oil filter, and a connecting plate disposed between the mounting plate and the oil filter, the connecting plate and the mounting plate being arranged at an angle, and an oil drip hole being provided at the bend of the two;

[0010] The bottom of the connecting plate extends into the smoke collection chamber with an oil guide plate, which is located above the oil drip hole.

[0011] The smoke collection chamber of this utility model has the following advantages compared with the prior art:

[0012] The smoke collection chamber of this utility model is equipped with an oil guide plate. The oil droplets formed by the condensation of flue gas on the inner surface of the oil mesh will not flow directly to the oil dripping hole, but will flow through the surface of the oil guide plate and then to the mounting plate. Thus, the two streams of oil droplets will not collide and accumulate at the oil dripping hole, which can avoid the difficulty of oil droplets formed on the outer surface of the oil mesh passing through the oil dripping hole.

[0013] In one embodiment, the height of the side of the oil guide plate away from the connecting plate is higher than the height of the lowest position of the oil guide plate.

[0014] In one embodiment, the connecting plate and the oil guide plate are an integral structure.

[0015] In one embodiment, multiple oil drip holes and multiple oil guide plates are provided, and the oil drip holes and multiple oil guide plates are provided in a one-to-one correspondence. The multiple oil drip holes are spaced apart along the width direction of the smoke inlet plate.

[0016] In one embodiment, the width of the oil guide plate is not less than the width of the oil drip hole.

[0017] In one embodiment, an oil baffle is further included, which is fitted to the mounting plate and located below the drip hole to guide oil droplets from the outer surface of the connecting plate to the drip hole.

[0018] In one embodiment, the oil mesh and the connecting plate form a cavity recessed into the smoke collection chamber.

[0019] In one embodiment, the length of the oil guide plate projected in the vertical direction is not less than the length of the oil drip hole projected in the vertical direction.

[0020] In one embodiment,

[0021] The second technical problem mentioned above is solved by the following technical solution:

[0022] A range hood includes a smoke collection chamber as described in any of the above embodiments.

[0023] Compared with the prior art, the range hood described in this utility model has the following beneficial effects:

[0024] The range hood of this utility model has an oil guide plate in the smoke collection chamber. The oil droplets formed by the condensation of smoke on the inner surface of the oil mesh will not flow directly to the oil drip hole, but will flow through the surface of the oil guide plate and then to the mounting plate. Thus, the two streams of oil droplets will not collide and accumulate at the oil drip hole, which can avoid the difficulty of oil droplets formed on the outer surface of the oil mesh passing through the oil drip hole.

[0036] See Figures 1 to 3 , Figure 1 A schematic diagram of the smoke inlet plate of a smoke collection chamber box according to an embodiment of the present invention is shown. Figure 2 This invention provides a side view of the smoke collection chamber and a schematic diagram of oil flow according to an embodiment of the present invention. Figure 3 It shows Figure 2 A magnified view of a portion of point A in the middle.

[0037] An embodiment of this utility model provides a smoke collection chamber for a range hood, including a smoke inlet plate 100. The smoke inlet plate 100 includes an inclined mounting plate 110 and an oil filter 120, and a connecting plate 130 disposed between the mounting plate 110 and the oil filter 120. The connecting plate 130 and the mounting plate 110 are arranged at an angle, and an oil drip hole 140 is provided at the bend of the two.

[0038] The bottom of the connecting plate 130 extends into the smoke collection chamber with an oil guide plate 131, which is located above the oil drip hole 140.

[0039] The aforementioned smoke collection chamber is equipped with an oil guide plate 131. When the range hood is working, the smoke will condense on the inner and outer surfaces of the oil mesh 120 to form two oil droplets. The inner oil droplets above the oil dripping hole 140 will flow from the connecting plate 130 through the surface of the oil guide plate 131 to the mounting plate 110, while the outer oil droplets will flow through the oil dripping hole 140 to the mounting plate 110. Thus, the inner and outer oil droplets will not collide and accumulate at the oil dripping hole 140, which can prevent the oil droplets formed on the outer surface of the oil mesh 120 from having difficulty passing through the oil dripping hole 140.

[0040] See Figure 3Furthermore, the height of the side of the oil guide plate 131 furthest from the connecting plate 130 is higher than the height of the lowest point of the oil guide plate 131. Thus, oil droplets passing through the oil guide plate 131 will not flow directly backward onto the mounting plate 110, but will flow to the left and right sides until they fall onto the mounting plate 110. Therefore, it avoids the obstruction of external oil droplets flowing on the mounting plate 110 by oil droplets falling from the top, and the two streams of oil droplets are staggered, ensuring further unobstructed oil flow.

[0041] It should be noted that "left and right sides" refers to... Figure 1 The width direction is shown.

[0042] As an optional solution, the oil guide plate 131 is arc-shaped.

[0043] See Figure 3 Furthermore, the connecting plate 130 and the oil guide plate 131 are an integral structure. That is, the connecting plate 130 and the oil guide plate 131 are manufactured as a single piece, so that oil droplets on the connecting plate 130 will not accumulate at the connection between the connecting plate 130 and the oil guide plate 131 due to the connecting structure.

[0044] See Figures 1 to 3 Multiple oil dripping holes 140 and multiple oil guide plates 131 are provided, and each oil dripping hole 140 and oil guide plate 131 is arranged in a one-to-one correspondence. The multiple oil dripping holes 140 are spaced apart along the width direction of the smoke inlet plate 100. In this way, the multiple oil dripping holes 140 increase the area of ​​the channel formed on the outside of the oil mesh 120 to enter the smoke collection chamber, thereby preventing the accumulation in a single oil dripping hole 140 and further improving the fluidity of oil droplets through the oil dripping holes 140.

[0045] See Figure 1 Furthermore, the width of the oil guide plate 131 is not less than the width of the oil drip hole 140. It can be understood that although it is possible to avoid completely blocking the oil drip hole 140 when the width of the oil guide plate 131 is less than the width of the oil drip hole 140, the effect of avoiding clogging the oil drip hole 140 is better if the width of the oil guide plate 131 is not less than the width of the oil drip hole 140.

[0046] See Figure 2-4 Furthermore, it also includes an oil baffle 150, which is fitted to the mounting plate 110 and located below the drip hole 140 to guide oil droplets from the outer surface of the connecting plate 130 to the drip hole 140. In this way, oil droplets condensing on the outer surface of the oil filter 120, if not passing through the drip hole 140 in time, can temporarily accumulate behind the oil baffle 150, preventing them from dripping directly onto the stovetop.

[0047] Check Figure 4The oil baffle 150 provided in this embodiment is a flat and elongated plate that can cover all the oil drip holes 140. In one embodiment, if there are multiple oil drip holes 140, multiple block-shaped oil baffles 150 can also be provided, as long as they can guide the oil droplets from the outer surface of the connecting plate 130 to the oil drip holes 140.

[0048] See Figure 1 The oil mesh 120 and the connecting plate 130 form a recessed chamber that extends into the smoke collection chamber. This allows the oil fumes to fill the chamber and condense sufficiently against the chamber's side walls, resulting in more condensed oil entering the smoke collection chamber.

[0049] See Figure 3 The length of the oil guide plate 131 projected in the vertical direction is not less than the length of the oil dripping hole 140 projected in the vertical direction. In this way, it can be ensured that when there is too much condensed oil, the oil droplets passing through the oil guide plate 131 will not drip into the oil dripping hole 140, thus avoiding oil blockage.

[0050] An embodiment of this utility model provides a range hood, which includes the smoke collection chamber box described in any of the above embodiments.

[0051] The smoke collection chamber of the range hood is equipped with an oil guide plate 131. The oil droplets formed by the condensation of smoke on the inner surface of the oil filter 120 will not flow directly to the oil drip hole 140, but will flow through the surface of the oil guide plate 131 and then onto the mounting plate 110. Thus, the two streams of oil droplets will not collide and accumulate at the oil drip hole 140, which can prevent the oil droplets formed on the outer surface of the oil filter 120 from having difficulty passing through the oil drip hole 140.

[0052] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0053] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
