Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to a smoke collecting device and a side-suction range hood. Background Art

[0002] With the improvement of people's quality of life, range hoods have gradually become an indispensable appliance in the kitchen. They are usually installed above the kitchen stove and can absorb the fumes generated during the cooking process, thereby purifying the kitchen environment and improving people's comfort when cooking.

[0003] Existing range hoods are generally divided into top-suction range hoods and side-suction range hoods according to the arrangement of the smoke inlet. In order to avoid blocking the user's line of sight, the smoke inlet of the top-suction range hood is usually far away from the stove, so the top-suction range hood has weak anti-interference ability and its oil smoke extraction effect is not as good as that of the side-suction range hood.

[0004] However, existing side-suction range hoods usually have a smoke baffle that rotatably covers the smoke inlet, so that it can be flipped outward to open the smoke inlet to absorb oil fumes when in use. However, the smoke inlet of the side-suction range hood is usually low and close to the stove, which makes it easy for the smoke baffle to hit when flipping the pan when frying, which will have an adverse effect on the user's cooking. Utility Model Content

[0005] In view of the problem that the smoke inlet of the existing side-suction range hood is usually low and close to the stove, which makes it easy for the pan to hit the smoke shield when cooking, which has an adverse effect on the user's cooking. The present application provides a smoke collection device and a side-suction range hood, which can improve the oil fume extraction effect while reducing the risk of the pan hitting the smoke shield.

[0006] In order to achieve at least one of the above advantages or other advantages and purposes of the utility model, the utility model provides a smoke collecting device, comprising:

[0007] Fan cover;

[0008] Oil cup;

[0009] A smoke collecting hood, wherein the smoke collecting hood is arranged between the fan hood and the oil cup, and the smoke collecting hood has a top smoke outlet connected to the fan hood, a bottom oil leakage end connected to the oil cup, and a lateral smoke inlet opened on the front side wall of the smoke collecting hood and arranged adjacent to the oil cup; and

[0010] A smoke baffle is movably arranged on the smoke hood to switch between a closed state and an open state; when the smoke baffle is in the closed state, the smoke baffle is attached to the front side wall of the smoke hood, and the lower edge of the smoke baffle is located above the lower edge of the side smoke inlet; when the smoke baffle is in the open state, the smoke baffle extends forward from the front side wall of the smoke hood, and the smoke baffle is located above the upper edge of the side smoke inlet.

[0011] According to an embodiment of the present application, when the smoke baffle is in the closed state, the lower edge of the smoke baffle is located above the upper edge of the lateral smoke inlet to completely open the lateral smoke inlet.

[0012] According to an embodiment of the present application, when the smoke baffle is in the closed state, the lower edge of the smoke baffle is adjacent to the upper edge of the lateral smoke inlet.

[0013] According to one embodiment of the present application, the height of the smoke baffle is smaller than the width of the lateral smoke inlet.

[0014] According to one embodiment of the present application, when the smoke baffle is in the closed state, the lower edge of the smoke baffle is located between the upper edge of the side smoke inlet and the lower edge of the side smoke inlet to partially cover the side smoke inlet.

[0015] According to one embodiment of the present application, an upper edge of the smoke baffle is adjacent to the upper edge of the lateral smoke inlet.

[0016] According to an embodiment of the present application, the upper edge of the smoke baffle is located above the upper edge of the lateral smoke inlet, and the upper edge of the smoke baffle is rotatably connected to the front side wall of the smoke collecting hood.

[0017] According to one embodiment of the present application, the smoke collection device further includes a driving mechanism arranged on the smoke collection hood, and the driving mechanism is drivingly connected to the smoke baffle to drive the smoke baffle to flip relative to the front side wall of the smoke collection hood; the driving mechanism includes a rotary driving motor and a curved rack meshing with the output shaft of the rotary driving motor, and one end of the curved rack is rotatably connected to the smoke baffle.

[0018] According to one embodiment of the present application, the front side wall of the smoke hood extends upwardly obliquely from the oil cup to the fan cover relative to the rear side wall of the smoke hood, and the thickness of the smoke hood adjacent to the oil cup is smaller than the thickness of the smoke hood adjacent to the fan cover.

[0019] According to another aspect of the present application, the present application further provides a side-suction range hood, comprising:

[0020] Any of the above-mentioned smoke collecting devices; and

[0021] A fan body is installed in a fan cover of the smoke collecting device.

[0022] In summary, since the smoke baffle in the open state extends forward from the front side wall to form a smoke collection area under the smoke baffle, when the oil smoke is large, the smoke baffle in the smoke collection device of the present application can be opened to form the smoke collection area while completely opening the side smoke inlet to facilitate the suction of oil smoke; at the same time, even if the side smoke inlet in the side-suction range hood is positioned lower and closer to the stove to obtain a better oil fume suction effect, the smoke baffle in the open state is located above the upper edge of the smoke inlet and is still far away from the stove, which can reduce the risk of hitting the smoke baffle when flipping the pot, thereby improving the user experience.

[0023] In addition, since the lower edge of the smoke baffle in the closed state is located above the lower edge of the side smoke inlet, the side smoke inlet is partially or fully open when the smoke baffle is in the closed state. Therefore, when the oil smoke is small, the smoke baffle in the smoke collection device of the present application can absorb the oil smoke through the side smoke inlet without opening, and the smoke baffle in the closed state will not affect the cooking operation.

[0038] Taking into account the problems that the smoke inlet of existing side-suction range hoods is usually low and close to the stove, which makes it easy for the pan to hit the smoke shield when cooking, and has an adverse effect on the user's cooking. The present application provides a smoke collection device and a side-suction range hood, which can improve the oil fume extraction effect while reducing the risk of the pan hitting the smoke shield.

[0039] Specifically, according to another aspect of the present application, Figures 1 to 6 As shown, one embodiment of the present application provides a side suction range hood, which may include a smoke collecting device 1 and a fan body (not shown in the figure) disposed on the smoke collecting device 1, for absorbing oil smoke. It is understandable that the range hood of the present application may also include, but is not limited to, a water tank, a water receiving box and / or a sensor to assist in completing the oil smoke absorbing function, which will not be described in detail in the present application.

[0040] More specifically, if Figure 1 and Figure 4As shown, the smoke collecting device 1 of the present application may include a fan cover 10, an oil cup 20, a smoke collecting cover 30 and a smoke baffle 40. The smoke collecting cover 30 is arranged between the fan cover 10 and the oil cup 20, and the smoke collecting cover 30 has a top smoke outlet 31 connected to the fan cover 10, a bottom oil leakage end 32 connected to the oil cup 20, and a lateral smoke inlet 33 opened on the front side wall 301 of the smoke collecting cover 30 and arranged adjacent to the oil cup 20. The smoke baffle 40 is movably arranged on the smoke hood 30 to switch between a closed state and an open state; when the smoke baffle 40 is in the closed state, the smoke baffle 40 is attached to the front side wall 301 of the smoke hood 30, and the lower edge 41 of the smoke baffle 40 is located above the lower edge 331 of the side smoke inlet 33; when the smoke baffle 40 is in the open state, the smoke baffle 40 extends forward from the front side wall 301 of the smoke hood 30, and the smoke baffle 40 is located above the upper edge 332 of the side smoke inlet 33. It can be understood that the number of lateral smoke inlet ports 33 in the smoke collection device 1 of the present application is only one, and the position on the smoke collection hood 30 is relatively low so as to be closer to the stove, so that the side-suction range hood of the present application is implemented as a low-suction range hood, so as to form a negative pressure area near the stove to improve the oil fume suction effect and achieve more efficient oil fume purification capabilities; in addition, the front side wall 301 mentioned in the present application refers to the side wall of the smoke collection hood 30 facing the user.

[0041] It is worth noting that since the smoke baffle 40 in the open state extends forward from the front side wall 301 to form a smoke collection area under the smoke baffle 40, when the oil smoke is large, the smoke baffle 40 in the smoke collecting device 1 of the present application can be opened to form the smoke collection area while completely opening the side smoke inlet 33 to facilitate the suction of oil smoke; at the same time, even if the side smoke inlet 33 in the side-suction range hood is located lower and closer to the stove to obtain a better oil smoke suction effect, the smoke baffle 40 in the open state is located above the upper edge 332 of the side smoke inlet 33 and is still far away from the stove, which can reduce the risk of hitting the smoke baffle 40 when flipping the pot, thereby improving the user experience.

[0042] In addition, since the lower edge 41 of the smoke baffle 40 in the closed state is located above the lower edge 331 of the side smoke inlet 33, the side smoke inlet 33 is partially or fully opened when the smoke baffle 40 is in the closed state. Therefore, when the oil smoke is small, the smoke baffle 40 in the smoke collection device 1 of the present application can absorb the oil smoke through the side smoke inlet 33 without opening, and the smoke baffle 40 in the closed state will not affect the cooking operation.

[0043] In addition, the distance between the lower edge 331 of the lateral smoke inlet 33 and the oil cup 20 may be between 0 mm and 100 mm.

[0044] For example, in the first example of the present application, Figures 1 to 3 As shown, when the smoke baffle 40 is in the closed state, the lower edge 41 of the smoke baffle 40 is located above the upper edge 332 of the lateral smoke inlet 33 to fully open the lateral smoke inlet 33. In this way, when the smoke baffle 40 is flipped relative to the front side wall 301 of the smoke collecting hood 30 to switch from the closed state to the open state, the smoke baffle 40 can always be located far away from the stove, which can not only prevent the smoke baffle 40 from hitting the pot placed on the stove during the flipping process, but also prevent the smoke baffle 40 in the open state from being hit when the pot is flipped, so that the state of the smoke baffle 40 can be switched at any time according to the size of the oil smoke of the stove without worrying about collision with the pot placed on the stove.

[0045] Alternatively, if Figure 1 and Figure 2 As shown, when the smoke baffle 40 is in the closed state, the lower edge 41 of the smoke baffle 40 is adjacent to the upper edge 332 of the side smoke inlet 33, so that the smoke baffle 40 is still relatively close to the side smoke inlet 33 when in the open state, so as to form a better smoke collecting area at the side smoke inlet 33, which is helpful for dealing with more oil smoke.

[0046] For example, the distance between the lower edge 41 of the smoke baffle 40 and the upper edge 332 of the lateral smoke inlet 33 is less than or equal to 30 mm. Preferably, when the smoke baffle 40 is in the closed state, the lower edge 41 of the smoke baffle 40 is flush with the upper edge 332 of the lateral smoke inlet 33, that is, the lower edge 41 of the smoke baffle 40 in the closed state can be close to the upper edge 332 of the lateral smoke inlet 33, so that the upper edge 42 of the smoke baffle 40 is as close to the upper edge 332 of the lateral smoke inlet 33 as possible.

[0047] Optionally, in the above first example of the present application, if Figure 1 As shown, the height H of the smoke baffle 40 is less than the width L of the lateral smoke inlet 33, which not only enables the upper edge 42 of the smoke baffle 40 to be closer to the lateral smoke inlet 33, thereby ensuring that the smoke baffle 40 is still close to the lateral smoke inlet 33 after being flipped open, thereby improving the smoke absorption effect, but also prevents the smoke baffle 40 in the open state from blocking the user's sight, thereby improving the user's cooking experience. It is understandable that in other examples of the present application, the height H of the smoke baffle 40 may be greater than or equal to the width L of the lateral smoke inlet 33, which will not be elaborated in the present application.

[0048] It is worth noting that in the second example of the present application, Figures 4 to 6As shown, when the smoke baffle 40 is in the closed state, the lower edge 41 of the smoke baffle 40 is located between the lower edge 331 and the upper edge 332 of the side smoke inlet 33 to partially cover the side smoke inlet 33, so that the flow area of ​​the side smoke inlet 33 is reduced when the smoke baffle 40 is in the closed state, which helps to increase the flow rate at the side smoke inlet 33 to accelerate the inhalation of oil smoke; at the same time, the side smoke inlet 33 can be fully opened / exposed when the smoke baffle 40 is in the open state to cope with a large oil smoke environment.

[0049] Alternatively, if Figure 5 and Figure 6 As shown, the upper edge 42 of the smoke baffle 40 is adjacent to the upper edge 42 of the side smoke inlet 33 and the upper edge 332 of the side smoke inlet 33, so that the smoke baffle 40 is closer to the side smoke inlet 33 after being flipped open, avoiding the accumulation of oil smoke between the smoke baffle 40 and the side smoke inlet 33, which is beneficial to improving the oil fume suction effect.

[0050] For example, the distance between the upper edge 42 of the smoke baffle 40 and the upper edge 332 of the lateral smoke inlet 33 is less than or equal to 30 mm. Preferably, when the smoke baffle 40 is in the open state, the upper edge 42 of the smoke baffle 40 is flush with the upper edge 332 of the lateral smoke inlet 33, that is, the upper edge 42 of the smoke baffle 40 in the open state can be close to the upper edge 332 of the lateral smoke inlet 33, so that the smoke baffle 40 can be as close to the lateral smoke inlet 33 as possible in the open state to avoid the accumulation of oil smoke therebetween.

[0051] According to the above embodiments of the present application, Figures 1 to 6 As shown, the front side wall 301 of the smoke hood 30 extends upwardly obliquely from the oil cup 20 to the fan cover 10 relative to the rear side wall 302 of the smoke hood 30, and the thickness of the smoke hood 30 adjacent to the oil cup 20 is less than the thickness of the smoke hood 30 adjacent to the fan cover 10, so that the side-suction range hood achieves an ultra-thin design to provide a larger placement space for cooking utensils and avoid structural interference. It can be understood that in other embodiments of the present application, the front side wall 301 of the smoke hood 30 can also be relatively parallel to the rear side wall 302 of the smoke hood 30, so that the thickness of the smoke hood 30 from the oil cup 20 to the fan cover 10 remains consistent, and this application will not elaborate on this; in addition, the thickness mentioned in this application refers to the size of the smoke hood 30 in the front-to-back direction.

[0052] Alternatively, if Figure 1 and Figure 4As shown, the upper edge 42 of the smoke baffle 40 is located above the upper edge 332 of the lateral smoke inlet 33, and the upper edge 42 of the smoke baffle 40 is rotatably connected to the front side wall 301 of the smoke collecting hood 30, so that the smoke baffle 40 can be flipped relative to the front side wall 301 to switch between the closed state and the open state.

[0053] Alternatively, if Figure 3 and Figure 6 As shown, the upper edge 42 of the smoke baffle 40 is pivotally connected to the front side wall 301 of the smoke hood 30, so that the position of the upper edge 42 of the smoke baffle 40 on the front side wall 301 remains unchanged when the smoke baffle 40 is flipped relative to the front side wall 301. It can be understood that in other examples of the present application, the upper edge 42 of the smoke baffle 40 can also be slidably hinged relative to the front side wall 301 of the smoke hood 30, so that when the smoke baffle 40 is flipped relative to the front side wall 301 to switch from a closed state to an open state, the upper edge 42 of the smoke baffle 40 can slide relative to the front side wall 301 toward the lateral smoke inlet 33, which is conducive to making the smoke baffle 40 in the open state closer to the lateral smoke inlet 33, ensuring that oil smoke is not easily accumulated between the two.

[0054] Alternatively, if Figure 3 and Figure 6 As shown, the smoke collecting device 1 further includes a driving mechanism 50 arranged on the smoke collecting hood 30, and the driving mechanism 50 is drivingly connected to the smoke baffle 40 to drive the smoke baffle 40 to flip relative to the front side wall 301 of the smoke collecting hood 30, so that the smoke baffle 40 automatically switches between the closed state and the open state.

[0055] For example, Figure 3 and Figure 6 As shown, the driving mechanism 50 may include a rotary driving motor (not shown) and a curved rack 51 meshed with the output shaft of the rotary driving motor, and one end of the curved rack 51 is rotatably connected to the smoke baffle 40. In this way, when the driving motor is working, the output shaft of the driving motor drives the curved rack 51 to extend or retract the front side wall 301 of the smoke hood 30, so as to drive the smoke baffle 40 to flip away from or cover the front side wall 301 and switch to an open state or a closed state. At the same time, the curved rack 51 mentioned in the present application rotates around the output shaft driven by the output shaft of the driving motor to avoid structural interference with the rear side wall 302 of the smoke hood 30, which helps to achieve an ultra-thin design of the smoke hood 30, so as to obtain an ultra-thin low-suction range hood.

[0056] It is worth noting that in some examples of the present application, the driving mechanism 50 can omit the curved rack 51, so that the output shaft of the rotary drive motor is connected to the upper edge 42 of the smoke shield 40, directly driving the smoke shield 40 to rotate around the upper edge 42 to achieve state switching; of course, in other examples of the present application, the driving mechanism 50 can also be implemented as a linear driving mechanism (such as a push rod motor, etc.) equipped with a connecting rod, and the two ends of the connecting rod are respectively rotatably connected to the push rod of the push rod motor and the smoke shield 40, and the state switching of the smoke shield 40 can still be achieved, which will not be elaborated in the present application.

[0057] In addition, in the above-mentioned embodiment of the present application, the fan body is assembled in the fan cover 10 of the smoke collecting device 1 to form an ultra-thin low-absorption range hood.

[0058] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
