[0038] like Figure 1 - Figure 4 As shown, the smoke collecting device provided by the utility model includes: a side smoke collecting part and an oil cup 200.

[0039] The side smoke collecting portion is arranged vertically and includes a reference plane 110 facing the front. In this embodiment, the reference plane 110 is a vertical plane, and in other feasible schemes, the reference plane 110 can also be an inclined plane inclined relative to the vertical, for example, the upper edge of the reference plane 110 is closer to the front.

[0040] The oil cup 200 is connected to the bottom end of the side smoke collecting section, and the opening of the oil cup 200 is set upward to receive the oil flowing out of the inside of the side smoke collecting section. At the same time, the lower edge of the reference plane 110 is projected vertically downward and falls on the inside of the opening. In other words, the reference plane 110 of the side smoke collecting section and the oil cup 200 are arranged in a front-to-back staggered manner, and the oil cup 200 is closer to the front. Therefore, the oil flowing along the reference plane 110 will enter the oil cup 200, preventing the oil from dripping onto the stove.

[0041] The distance between the reference surface 110 and the front surface of the oil cup in the front-rear direction is approximately 3-5 mm.

[0042] like Figure 5 As shown, the reference surface 110 is provided with a first recessed portion 120 that is recessed toward the inner side of the side smoke collecting portion, and a side smoke inlet is provided in the first recessed portion 120. The provision of the first recessed portion 120 can provide a larger smoke collecting area and improve the smoking efficiency. At the same time, the first recessed portion 120 is approximately located in the middle of the reference surface 110, and the oil and dirt flowing out of the first recessed portion 120 flows from top to bottom onto the reference surface 110, and finally flows into the oil cup 200.

[0043] In the present embodiment, there are two side smoke inlets, and a partition longitudinal beam 130 is provided in the first recess 120. The partition longitudinal beam 130 is used to separate two laterally adjacent side smoke inlets. The two side smoke inlets match two stove eyes. After being separated by the partition longitudinal beam 130, the left and right smoke collecting areas can be separated, so as to better smoke inhalation near the stove eyes.

[0044] like Figure 5 As shown, the front side of the partition longitudinal beam 130 is located behind the reference surface 110 , and the oil flowing down the front side of the partition longitudinal beam 130 can be retained in the first recess 120 and then flow onto the reference surface 110 .

[0045] The side smoke collecting part is rotatably connected with a flap 300 for opening and closing the side smoke inlet. When the flap 300 is opened, a smoke collecting structure can be formed to collect more oil smoke to the side smoke inlet. When the flap 300 is closed, the flap 300 can cover the side smoke inlet, which is more beautiful.

[0046] When the flap 300 is in a closed state, the flap 300 is spaced apart from the reference surface 110 in the front-rear direction, thereby preventing oil stains on the back of the flap 300 from contaminating the reference surface 110 .

[0047] A support portion 140 protruding forward is provided on the reference surface 110, and the front side surface of the support portion 140 is on the same plane as the front side surface of the oil cup 200, so that when the flap 300 is in a closed state, the back side of the flap 300 contacts the front side surfaces of the support portion 140 and the front side surfaces of the oil cup 200.

[0048] The support portion 140 can be located on the left side, right side and upper side of the first recess 120, and plays a certain supporting role on the closed flap 300 to prevent the flap 300 from being completely pressed on the oil cup 200. In the up-down direction, the bottom end of the support portion 140 is spaced apart from the opening of the oil cup 200, that is, the lower edge of the reference surface 110 is completely connected to the opening of the oil cup 200, and the oil stains on the reference surface 110 all enter the oil cup 200.

[0049] The front side surface of the support portion 140 and the reference surface 110 can be smoothly transitioned through a transition arc surface to reduce the edges and corners.

[0050] like Figure 2 As shown, when the flap 300 is in use, oil stains will adhere to the back side thereof, and therefore, an oil guide member 310 may be provided on the back side of the flap 300. When the flap 300 is in a closed state, the oil outlet end of the oil guide member 310 is vertically projected downward to fall on the inner side of the opening, that is, the oil stains flowing down the back side of the flap 300 will drip into the oil cup 200 along the oil guide member 310, or drip into the first recess, and then drip into the oil cup 200 along the reference surface 110.

[0051] The oil guide member 310 may be wedge-shaped, or may be an inclined plate that inclines from top to bottom toward the inner side of the side smoke collecting portion.

[0052] When the flap 300 is in a closed state, the flap is arranged vertically, and the lower edge of the flap 300 is flush with or lower than the lower edge of the oil cup, so that the flap 300 completely covers the oil cup, which is more beautiful. At the same time, when only the smoke inlet is working, the oil smoke will only adhere to the front side of the flap 300 on the side, and the integrated flap is easier to wipe.

[0053] like Figure 6 As shown, the smoke collecting device includes a driving mechanism 400, which is respectively connected to the flap 300 and the side smoke collecting part, and is used to drive the flap 300 to open or close.

[0054] Specifically, the driving mechanism 400 includes a push rod motor 410 , a first connecting arm 420 and a second connecting arm 430 .

[0055] The first connecting arm 420 includes a first end and a second end opposite to each other, and the second connecting arm 430 includes a third end and a fourth end opposite to each other. A bracket 440 is provided on the inner wall of the side smoke collecting part, and the main body of the push rod motor 410 is hinged to the bracket 440. The telescopic end, the first end and the third end of the push rod motor 410 are hinged through the same hinge shaft. A fixing seat 450 is also provided on the inner wall of the side smoke collecting part, and the second end is hinged to the fixing seat 450. The fourth end is hinged to the flap 300. When the push rod motor 410 is extended, the flap flips outward; when the push rod motor 410 is retracted, the flap rotates in the opposite direction to close the side smoke inlet. When the flap is opened, a main smoke inlet is formed, and most of the rising oil smoke is sucked into the body from this oil smoke inlet. If the oil smoke is too large, a small part of the oil smoke turns over the smoke collecting plate and continues to rise upward. At this time, there is still negative pressure at the top smoke inlet, and a small smoke collecting cavity is formed with the suspended switch module, and a small part of the oil smoke is sucked from the top smoke inlet. Even if the oil smoke cannot enter from the side smoke inlet for the first time, it will be sucked into the machine body from the top smoke inlet for a second time, so that the oil smoke will not escape.

[0056] There are two second connecting arms 430, which are respectively located on the left and right sides of the flap 300. The second connecting arms 430 can be a plate-shaped structure. After the flap 300 is opened, the two second connecting arms 430 can form a cover with the flap 300 to reduce the escape of oil smoke from the side.

[0057] like Figure 1 As shown, the bottom surface of the side smoke collecting portion is an inclined surface, and from front to back, the bottom surface of the side smoke collecting portion is inclined upward, so that the oil stains on the bottom surface of the side smoke collecting portion can flow into the opening of the oil cup 200.

[0058] The range hood provided by the utility model comprises the above-mentioned smoke collecting device. Since the range hood provided by the utility model adopts the above-mentioned smoke collecting device, the range hood provided by the utility model also has the advantages of the smoke collecting device.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
