Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to a top-side double-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 usually include top suction range hoods and side suction range hoods. However, since the power source of the top suction range hood is far away from the stove, the suction effect of the power source is reduced and the oil smoke cannot be completely sucked out. The side suction range hood has a fast rising speed of the oil smoke and is unable to deal with a small amount of oil smoke escaping upward. Therefore, some range hoods that combine top suction and side suction have appeared, also known as Oujin integrated range hoods, which fully utilize the advantages of top suction and side suction and achieve better suction effect. However, although this Oujin integrated range hood combines the advantages of top suction and side suction, the performance loss of the centrifugal fan is too large due to the vertical placement of the centrifugal fan, and the oil smoke suction effect is still poor.

[0004] In order to solve this problem, the existing improved Oujin integrated range hood places the centrifugal fan at an angle, and sets a telescopic mechanism in the horizontal smoke collecting hood to extend and retract the filter-type telescopic plate according to the amount of oil fume air. The side air inlet is used as the main and the top air inlet is used as the auxiliary, so as to realize all-round air intake and achieve better oil fume extraction effect.

[0005] However, this improved European integrated range hood has a top suction air inlet on the retractable plate, which results in the horizontal oil fume path being too long in the extended state and being located below the fan. Therefore, when the oil fume enters from the retractable plate, it needs to turn before entering the subsequent exhaust channel, which affects the oil fume suction effect. In addition, since the top suction oil fume port will accumulate oil fume, the oily dirt cooled on the filter-type retractable plate will flow along the oil fume path onto the smoke hood on which it is mounted. Therefore, there will inevitably be a thick oil layer between the retractable plate and the smoke hood, which will increase the retractable resistance and cause a thick oil layer to adhere to the filter, thus causing the filter to be blocked. Utility Model Content

[0006] The existing range hoods not only increase the flow path of top-intake oil fumes, affecting the oil fume suction effect, but also accumulate oil fumes between the telescopic plate and the smoke collecting hood, resulting in increased telescopic resistance and filter clogging. The present application provides a top-side double-suction range hood, which can reduce the flow path of top-intake oil fumes while preventing the increase in resistance of the telescopic mechanism caused by oil accumulation, thereby avoiding clogging of the top suction smoke inlet by oil.

[0007] 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 top-side double-suction range hood, comprising:

[0008] A fan, comprising a fan box and a fan body arranged in the fan box;

[0009] A smoke collecting hood, comprising a transverse hood body located below the fan box and provided with a top smoke inlet, and a vertical hood body extending downward from the transverse hood body and provided with a side smoke inlet; and

[0010] The smoke shield is slidably mounted outside the transverse shield body to open or close the top smoke inlet.

[0011] In one embodiment of the present application, the top smoke inlet is composed of a plurality of hole-shaped openings.

[0012] In one embodiment of the present application, a plurality of the hole-like openings are arranged at intervals along the left-right direction on the lower wall of the transverse cover body.

[0013] In one embodiment of the present application, the hole-shaped opening is a rounded rectangular hole extending along the front-to-back direction.

[0014] In one embodiment of the present application, the hole-shaped opening is an elliptical hole or a circular hole.

[0015] In one embodiment of the present application, the top-side double-suction range hood further includes a driving mechanism drivingly connected to the smoke shielding hood, for driving the smoke shielding hood to slide forward and backward relative to the transverse cover body.

[0016] In one embodiment of the present application, the driving mechanism is a guide rail type mechanism arranged between the outer wall of the transverse cover body and the inner wall of the smoke shield; the guide rail type mechanism includes a pair of guide rails respectively arranged on the left and right outer walls of the transverse cover body and a pair of slide grooves respectively arranged on the left and right inner walls of the smoke shield and matching the guide rails.

[0017] In one embodiment of the present application, the top-side double-suction range hood further includes an interactive interface, and the interactive interface is arranged on the front side wall of the smoke shield.

[0018] In one embodiment of the present application, the top-side double-suction range hood further includes an oil cup disposed below the vertical cover body; an oil leakage port communicating with the oil cup is formed at the bottom of the vertical cover body.

[0019] In one embodiment of the present application, the top-side double-suction range hood further includes an oil fume sensor, which is arranged on the smoke collecting hood and / or the smoke shielding hood to detect the concentration of oil fume.

[0020] In summary, in the top-side double-suction range hood of the present application, since the top suction smoke inlet is directly opened on the horizontal cover body located below the fan box, after the smoke enters the horizontal cover body through the top suction smoke inlet, it can flow directly to the fan box without turning, thereby shortening the flow path of the top suction smoke, realizing direct suction and discharge of the horizontal cover body, and improving the effect of top suction smoke.

[0021] In addition, since the smoke shielding hood is arranged outside the transverse cover body to wrap the transverse cover body in a wrapped shape, after the oil smoke enters the interior of the transverse cover body from the top smoke inlet, even if fluid oil stains are formed after cooling, they will only be formed on the inner wall of the transverse cover body and will flow to the vertical cover body through the inner wall of the transverse cover body, and a large amount of oil stains will not be formed in the gap between the smoke shielding hood and the transverse cover body, effectively avoiding the increase of the sliding resistance of the smoke shielding hood due to the accumulation of oil stains.

[0032] Considering that the existing range hoods not only increase the flow path of the top-intake oil smoke, affecting the oil smoke suction effect, but also accumulate oil smoke between the telescopic plate and the smoke collection hood, resulting in increased telescopic resistance and filter clogging. Therefore, the present application creatively provides a top-side double-suction range hood, which can reduce the flow path of the top-intake oil smoke, prevent the increase of resistance caused by the accumulation of oil and dirt in the telescopic mechanism, and avoid the top suction smoke inlet being blocked by oil and dirt.

[0033] Specifically, Figure 1 and Figure 2 As shown, one embodiment of the present application provides a top-side double-suction range hood 1, which may include a fan 10, a smoke collecting hood 20, and a smoke shielding hood 30. 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 smoke suction function, which will not be described in detail in the present application.

[0034] More specifically, if Figure 1 and Figure 2 As shown, the fan 10 includes a fan box 11 and a fan body (not shown) disposed in the fan box 11. The smoke collecting hood 20 includes a transverse hood body 21 located below the fan box 11 and having a top smoke inlet 210, and a vertical hood body 22 extending downward from the transverse hood body 21 and having a side smoke inlet 220. The smoke shielding hood 30 is slidably mounted outside the transverse hood body 21 to open or close the top smoke inlet 210.

[0035] In this way, Figure 2 As shown, when the top-side double-suction range hood 1 of the present application is in a cooking environment with less oil smoke, the smoke shield 30 slides backward relative to the lateral cover body 21 to close the top suction smoke inlet 210, and distributes the smoke flow only to the side suction smoke inlet 220 closer to the cooking stove, so that the side suction smoke inlet 220 has a greater suction force to suck out the small oil smoke; Figure 1As shown, when the top-side double-suction range hood 1 of the present application is in a cooking environment with relatively large amounts of oil smoke, the smoke shield 30 slides forward relative to the lateral cover body 21 to open the top smoke inlet 210 while forming a larger smoke collecting area at the top smoke inlet 210, so that the top-side double-suction range hood 1 not only distributes the smoke flow to the side smoke inlet 220 and the top smoke inlet 210 at the same time, but also utilizes the forwardly extended smoke shield 30 to play a smoke shielding role to prevent smoke escape.

[0036] It is worth noting that, since the top suction smoke inlet 210 is directly opened on the transverse cover body 21 located below the fan box 11, after the oil smoke enters the transverse cover body 21 through the top suction smoke inlet 210, it can flow directly to the fan box 11 without turning, shortening the flow path of the top suction oil smoke, achieving direct suction and discharge of the transverse cover body 21, and improving the effect of top suction oil smoke. In addition, since the smoke shield 30 is sleeved outside the transverse cover body 21 and wraps the transverse cover body 21 in a wrapped shape, after the oil smoke enters the interior of the transverse cover body 21 from the top suction smoke inlet 210, even if fluid oil stains are formed after cooling, they will only be formed on the inner wall of the transverse cover body 21 and will flow to the vertical cover body 22 through the inner wall of the transverse cover body 21, and will not form a large amount of oil stains in the gap between the smoke shield 30 and the transverse cover body 21, effectively avoiding the increase of the sliding resistance of the smoke shield 30 due to the accumulation of oil stains.

[0037] For example, Figure 1 As shown, the top smoke inlet 210 may be composed of a plurality of hole-shaped openings 211 .

[0038] Alternatively, if Figure 1 As shown, a plurality of hole-like openings 211 are arranged at intervals along the left-right direction on the lower wall of the transverse cover body 21. It is worth noting that, although in the above-mentioned examples of the present application, the top smoke inlet 210 includes a row of hole-like openings 211, in other examples of the present application, the top smoke inlet 210 may also include two or more rows of hole-like openings 211. In this way, although each row of hole-like openings 211 is formed by a plurality of hole-like openings 211 arranged at intervals, since it is difficult for a large amount of oil to accumulate in the narrow gap between the transverse cover body 21 and the smoke shield 30, even if the area of ​​each hole-like opening is small, it is not easy for the smoke shield 30 to block the top smoke inlet 210 with oil when sliding back and forth relative to the transverse cover body 21.

[0039] Alternatively, if Figure 1 As shown, the hole-shaped opening 211 is implemented as a rounded rectangular hole extending along the front-to-back direction. Of course, in other examples of the present application, the hole-shaped opening 211 can also be implemented as an elliptical hole, a circular hole or a hole of other geometric shapes, which will not be described in detail in the present application.

[0040] It is worth noting that in order to realize the automatic sliding of the smoke shield 30 relative to the transverse shield body 21, as shown in FIG. Figure 1 As shown, the top-side double-suction range hood 1 of the present application may further include a driving mechanism 40 drivingly connected to the smoke shield 30 , for driving the smoke shield 30 to slide forward and backward relative to the transverse cover body 21 to automatically open or close the top suction smoke inlet 210 .

[0041] Alternatively, if Figure 1 As shown, the driving mechanism 40 is implemented as a guide rail type mechanism disposed between the outer side wall of the transverse cover body 21 and the inner side wall of the smoke shield 30, so as to avoid contact with the oil accumulated on the inner side wall of the transverse cover body 21 while driving the smoke shield 30 to slide forward and backward relative to the transverse cover body 21, thereby ensuring the smooth driving of the guide rail type mechanism. It is understandable that in other examples of the present application, the driving mechanism 40 can also be implemented as, but not limited to, mechanisms such as a linear motor, an electric push rod, a hydraulic rod or a cylinder, as long as the smoke shield 30 can be automatically slid forward and backward relative to the transverse cover body 21, and the present application will not elaborate on this.

[0042] Alternatively, if Figure 1 As shown, the guide rail mechanism includes a pair of guide rails 41 respectively arranged on the left and right outer walls of the transverse cover body 21 and a pair of slide grooves (not shown in the figure) respectively arranged on the left and right inner walls of the smoke shield 30 and matching the guide rails 41, so as to ensure that the smoke shield 30 slides smoothly back and forth relative to the transverse cover body 21.

[0043] Alternatively, if Figure 1 and Figure 2 As shown, the top-side double-suction range hood 1 further includes an interactive interface 50, which is disposed on the front side wall of the smoke shield 30, so that the user can operate the interactive interface 50 to execute the required control instructions. For example, the user can control the operation of the driving mechanism 40 by operating the interactive interface 50 to drive the smoke shield 30 to slide forward and backward relative to the horizontal cover body 21; or the user can also control the opening or closing of the fan 10 by operating the interactive interface 50.

[0044] According to the above embodiments of the present application, Figure 1 and Figure 2 As shown, the top-side double-suction range hood 1 may also include an oil cup 60 arranged below the vertical cover body 22; an oil leakage port (not shown in the figure) connected to the oil cup 60 is opened at the bottom of the vertical cover body 22, so that the oil stains flowing down through the horizontal cover body 21 and the vertical cover body 22 of the smoke hood 20 can flow into the oil cup 60 through the oil leakage port.

[0045] In addition, if Figure 1 and Figure 2As shown, the top-side double-suction range hood 1 of the present application may further include a smoke sensor 70, which is arranged on the smoke collecting hood 20 and / or the smoke shielding hood 30, and is used to detect the concentration of the smoke, so that the top-side double-suction range hood 1 can adaptively adjust the sliding degree of the smoke shielding hood 30 relative to the transverse cover body 21 based on the level of the smoke concentration, thereby adjusting the size of the smoke collection area. At the same time, if the top suction smoke inlet 210 is composed of multiple rows of hole-shaped openings 211, the sliding degree of the smoke shielding hood 30 relative to the transverse cover body 21 can also adjust the number of hole-shaped openings 211 that are opened, thereby adjusting the size of the smoke collection area and the area of ​​the smoke inlet, so as to achieve the regulation of the smoke suction capacity under different smoke working conditions.

[0046] 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.

[0047] 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.
