Description

Technical Field

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

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

[0003] Existing range hoods usually include top - suction range hoods and side - suction range hoods. However, for the top - suction range hood, the suction effect of the power source is reduced because the power source is far from the stove, and the oil fumes cannot be completely sucked out. For the side - suction range hood, it is powerless against a small number of oil fumes that escape upward due to the relatively fast rising speed of the oil fumes. Therefore, some range hoods that combine top - suction and side - suction, also known as European - style range hoods, have emerged. They make full use of the advantages of top - suction and side - suction and achieve a better suction effect.

[0004] However, although this European - style range hood combines the advantages of top - suction and side - suction, for cooking scenarios using high - pots such as multi - layer steamers, generally, a European - style range hood with a higher space size is required, or a range hood without a flip - up baffle is used. If a European - style range hood is used, although the smoke - collecting area is large, for cooking scenarios using low - pots such as frying pans, the distance from the smoke source is far, resulting in a relatively poor oil - fume suction effect. If a range hood without a flip - up baffle is used, the smoke - collecting area is relatively small and far from the smoke source, and the oil - fume suction effect for cooking scenarios using low - pots such as frying pans is also poor. Summary of the Utility Model

[0005] Aiming at the problem that the existing range hoods, when satisfying cooking scenarios with high - pots such as multi - layer steamers, will result in a relatively poor oil - fume suction effect because the distance from the smoke source is far in cooking scenarios with low - pots such as frying pans; the present application provides a top - side dual - suction range hood, which can take into account both high - pot and low - pot cooking scenarios and obtain a better oil - fume suction effect.

[0006] In order to achieve at least one of the above advantages or other advantages and purposes of the present utility model, the present utility model provides a top - side dual - suction range hood, including:

[0007] A blower box;

[0008] A smoke - collecting cavity, including a side - part cavity longitudinally extending from the blower box and communicating with the blower box, and a top - part cavity horizontally extending from the side - part cavity and communicating with the side - part cavity. A side - suction air inlet located below the top - part cavity is provided on the front wall of the side - part cavity, and a top - suction air inlet is provided on the bottom wall of the top - part cavity;

[0009] A smoke baffle, which is rotatably arranged outside the side cavity and below the top cavity to selectively open or close the side air intake; and

[0010] A flow dividing plate, which is rotatably arranged inside the side cavity and adjacent to the top cavity to selectively open or close the communication port between the top cavity and the side cavity.

[0011] In an embodiment of the present application, when the top - side dual - suction range hood is switched to the low - pot cooking mode, the smoke baffle flips forward relative to the smoke collecting cavity to open the side air intake; when the top - side dual - suction range hood is switched to the high - pot cooking mode, the smoke baffle flips backward relative to the smoke collecting cavity to close the side air intake, and the flow dividing plate flips backward to open the communication port between the top cavity and the side cavity.

[0012] In an embodiment of the present application, when the top - side dual - suction range hood is in the low - pot cooking mode, the flow dividing plate can flip relative to the side cavity to switch between the side - suction flow - dividing state and the dual - suction flow - dividing state; when the flow dividing plate is in the side - suction flow - dividing state, the flow dividing plate flips forward to close the communication port between the top cavity and the side cavity, so that the channel between the top air intake and the blower box is blocked; when the flow dividing plate is in the dual - suction flow - dividing state, the flow dividing plate flips backward to open the communication port between the top cavity and the side cavity, so that the channels between the top air intake and the side air intake and the blower box are both conducted.

[0013] In an embodiment of the present application, the top - side dual - suction range hood further includes a smoke sensor disposed in the top cavity and in front of the top air intake.

[0014] In an embodiment of the present application, when the top - side dual - suction range hood is in the high - pot cooking mode, the flow dividing plate can further flip backward relative to the side cavity to block the channel between the side air intake and the blower box, so that the flow dividing plate is in the top - suction flow - dividing state.

[0015] In an embodiment of the present application, the flow dividing plate is rotatably connected to the part where the front wall of the side cavity intersects with the bottom wall of the top cavity.

[0016] In an embodiment of the present application, the width of the flow dividing plate is greater than the distance between the bottom wall and the top wall of the top cavity on the front wall of the side cavity.

[0017] In one embodiment of the present application, the width of the flow splitter is equal to the distance between the front wall and the rear wall of the side cavity on the plane where the bottom wall of the top cavity is located.

[0018] In one embodiment of the present application, the flow splitter includes a rigid plate body rotatably connected to the front wall of the side cavity and a flexible seal protruding from the edge of the rigid plate body.

[0019] In one embodiment of the present application, the front side edge of the rigid plate body is pivotally connected to the front wall of the side cavity; the flexible seal wraps the rear side edge, the left side edge, and the right side edge of the rigid plate body.

[0020] In summary, in the low-pot cooking scenario, the top-side dual-suction range hood can be switched to the low-pot cooking mode. At this time: the smoke baffle can be flipped forward relative to the smoke collecting cavity, which can not only open the side suction air inlet adjacent to the low-pot smoke source, but also form a negative pressure smoke gathering area near the side suction air inlet, so as to improve the smoke extraction effect in the low-pot cooking scenario. In the high-pot cooking scenario, the top-side dual-suction range hood can be switched to the high-pot cooking mode. At this time: the smoke baffle can be flipped backward relative to the smoke collecting cavity to close the side suction air inlet, so that the pot placement space below the top cavity is not blocked, and the smoke baffle is prevented from interfering with high pots such as multi-layer steamers; and the flow splitter can be flipped backward relative to the smoke collecting cavity to open the communication port between the top cavity and the side cavity, so that the channel between the top suction air inlet and the blower box is conducted, so as to form a negative pressure smoke gathering area at the top suction air inlet adjacent to the high-pot smoke source, which helps to improve the smoke extraction effect in the high-pot cooking scenario.

[0021] In addition, when the top-side dual-suction range hood of the present application is in the low-pot cooking mode: the flow splitter can either be flipped forward to close the communication port between the top cavity and the side cavity, so that the channel between the top suction air inlet and the blower box is blocked, while the channel between the side suction air inlet and the blower box is conducted, ensuring that the smoke can only enter the smoke collecting cavity from the side suction air inlet and flow into the blower box, so as to meet the application requirements of small-flow smoke; or it can be flipped backward to open the communication port between the top cavity and the side cavity, so that the channels of the top suction air inlet and the side suction air inlet are respectively conducted with the blower box, so that while ensuring that most of the smoke can enter the smoke collecting cavity from the side suction air inlet and flow into the blower box, a small part of the escaping smoke can enter the smoke collecting cavity from the top suction air inlet and flow into the blower box, which is convenient to meet the application requirements of large-flow smoke.

[0029] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0030] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0035] Considering that existing range hoods cannot simultaneously meet the cooking scenarios of low pots such as woks and high pots such as multi-layer steamers, that is, either to meet the oil fume extraction requirements of low pot cooking scenarios, a baffle is set to lower the smoke collection area, but this baffle will interfere with the structure of multi-layer steamers and cannot be used for high pot cooking scenarios, or to meet the oil fume extraction requirements of high pot cooking scenarios, the baffle is not set, but this will result in a relatively long distance from the smoke source during low pot cooking scenarios, resulting in poor oil fume extraction effect. Therefore, the present application creatively provides a top-side dual-suction range hood, which can take into account both high pot and low pot cooking scenarios and obtain a better oil fume extraction effect.

[0036] Specifically, as Figures 1 to 5 shown, an embodiment of the present application provides a top-side dual-suction range hood 1, which may include a blower box 10, a smoke collection cavity 20 located below the blower box 10 and communicating with the blower box 10, a baffle 30 disposed outside the smoke collection cavity 20, and a flow splitter 40 disposed inside the smoke collection cavity 20. It can be understood that the range hood of the present application may also but is not limited to include a control board, a water tank or a water receiving box to assist in completing the oil fume extraction function, which will not be elaborated herein.

[0037] More specifically, as Figure 2 、 Figure 3 and Figure 5As shown, the smoke collecting cavity 20 may include a side cavity 21 longitudinally extending from the blower box 10 and communicating with the blower box 10, and a top cavity 22 transversely extending from the side cavity 21 and communicating with the side cavity 21; a side smoke inlet 201 is formed in the front wall of the side cavity 21 and is located below the top cavity 22; a top smoke inlet 202 is formed in the bottom wall of the top cavity 22. The smoke baffle 30 is flipably arranged outside the side cavity 21 and below the top cavity 22 to selectively open or close the side smoke inlet 201. The flow dividing plate 40 is flipably arranged inside the side cavity 21 and adjacent to the top cavity 22 to selectively open or close the communication port between the top cavity 22 and the side cavity 21, so that the channel between the top smoke inlet 202 and the blower box 10 is conducted or blocked. It can be understood that the smoke baffle 30 and the flow dividing plate 40 mentioned in the present application can, but are not limited to, realize the flipping function through a motion mechanism such as a motor, and the present application will not elaborate on this.

[0038] Thus, as Figures 1 to 3 shown, in the low-pot cooking scenario, the top-side dual-suction range hood 1 can be switched to the low-pot cooking mode. At this time: the smoke baffle 30 can flip forward relative to the smoke collecting cavity 20, which can not only open the side smoke inlet 201 adjacent to the low-pot smoke source, but also form a negative pressure smoke gathering area near the side smoke inlet 201, so as to improve the smoke extraction effect in the low-pot cooking scenario. And as Figure 4 and Figure 5 shown, in the high-pot cooking scenario, the top-side dual-suction range hood 1 can be switched to the high-pot cooking mode. At this time: the smoke baffle 30 can flip backward relative to the smoke collecting cavity 20 to close the side smoke inlet 201, so that the pot placement space below the top cavity 22 is not blocked, and the smoke baffle 30 is prevented from interfering with a high pot G such as a multi-layer steamer; and the flow dividing plate 40 can flip backward relative to the smoke collecting cavity 20 to open the communication port between the top cavity 22 and the side cavity 21, so that the channel between the top smoke inlet 202 and the blower box 10 is conducted, so as to form a negative pressure smoke gathering area at the top smoke inlet 202 adjacent to the high-pot smoke source, which helps to improve the smoke extraction effect in the high-pot cooking scenario. It can be understood that the low-pot smoke source mentioned in the present application refers to the top of a low pot D such as a frying pan, and the smoke emitted during cooking is closer to the side smoke inlet 201; the high-pot smoke source mentioned in the present application refers to the top of a high pot G such as a multi-layer steamer, and the smoke emitted from the pot top during cooking is closer to the top smoke inlet 202.

[0039] It should be noted that in the low-pot cooking scenario, when the oil fume flow rate is small, all the oil fume can be completely sucked in through the side oil fume inlet 201; while when the oil fume flow rate is large, not all the oil fume can be sucked in through the side oil fume inlet 201, and there will be a problem of partial oil fume escaping. When the top-side dual-suction range hood 1 of the present application is in the low-pot cooking mode: as Figure 2 shown, the diversion plate 40 can be flipped forward to close the communication port between the top cavity 22 and the side cavity 21, so that the channel between the top oil fume inlet 202 and the blower box 10 is blocked, while the channel between the side oil fume inlet 201 and the blower box 10 is conducted, ensuring that the oil fume can only enter the smoke collecting cavity 20 through the side oil fume inlet 201 and flow into the blower box 10 to meet the application requirements of small-flow oil fume; as Figure 3 shown, the diversion plate 40 can also be flipped backward to open the communication port between the top cavity 22 and the side cavity 21, so that the channels between the top oil fume inlet 202 and the side oil fume inlet 201 and the blower box 10 are both conducted, so that while ensuring that most of the oil fume can enter the smoke collecting cavity 20 through the side oil fume inlet 201 and flow into the blower box 10, a small part of the escaping oil fume can enter the smoke collecting cavity 20 through the top oil fume inlet 202 and flow into the blower box 10, which is convenient to meet the application requirements of large-flow oil fume.

[0040] In other words, in the low-pot cooking mode, as Figure 2 and Figure 3 shown, the diversion plate 40 can distribute the oil fume flow rate entering the smoke collecting cavity 20 through the side oil fume inlet 201 and the top oil fume inlet 202, so that the diversion plate 40 of the top-side dual-suction range hood 1 can be switched between the side-suction diversion state and the dual-suction diversion state, that is: as Figure 2 shown, when the oil fume flow rate is small, the diversion plate 40 is flipped forward to block the channel between the top oil fume inlet 202 and the blower box 10, and all the oil fume flow rate is distributed to the side oil fume inlet 201, so that all the oil fume enters the smoke collecting cavity 20 through the side oil fume inlet 201. At this time, the diversion plate 40 of the top-side dual-suction range hood 1 is in the side-suction diversion state; while as Figure 3 shown, when the oil fume flow rate is large, the diversion plate 40 is flipped backward to conduct the channel between the top oil fume inlet 202 and the blower box 10, and the oil fume flow rate is distributed to the side oil fume inlet 201 and the top oil fume inlet 202 in proportion, so that a part of the oil fume enters the smoke collecting cavity 20 through the side oil fume inlet 201, and another part of the oil fume escaping from the side oil fume inlet 201 enters the smoke collecting cavity 20 through the top oil fume inlet 202. At this time, the diversion plate 40 of the top-side dual-suction range hood 1 is in the dual-suction diversion state.

[0041] In addition, as Figure 5As shown, in the high-pressure cooker cooking environment, since the smoke baffle 30 closes the side suction inlet 201, all the cooking fumes enter the smoke collecting cavity 20 from the top suction inlet 202. Therefore, the flow dividing plate 40 of the top and side dual-suction range hood 1 can be in the top suction flow dividing state, that is, the flow dividing plate 40 further turns backward to block the passage between the side suction inlet 201 and the blower box 10, and distributes all the cooking fume flow to the top suction inlet 202, so that all the cooking fumes enter the smoke collecting cavity 20 through the top suction inlet 202.

[0042] Optionally, the flow area of the side suction inlet 201 is larger than that of the top suction inlet 202, so that the side suction inlet 201 is the main smoke inlet and the top suction inlet 202 is the auxiliary smoke inlet, which is convenient to meet the smoke suction requirements of different cooking fume flows. For example, the side suction inlet 201 can be, but is not limited to, implemented as a strip-shaped opening extending along the left-right direction of the side cavity 21; the top suction inlet 202 can be, but is not limited to, implemented as a grid-shaped opening extending along the front-back direction of the top cavity 22.

[0043] Optionally, as Figure 1 and Figure 4 shown, the top and side dual-suction range hood 1 further includes a smoke sensor 50 disposed in the top cavity 22 and in front of the top suction inlet 202. In this way, when the smoke sensor 50 does not detect the escape of cooking fumes above the smoke baffle 30, it indicates that the cooking fume flow is small at this time, and the flow dividing plate 40 is controlled to turn forward to close the communication port between the top cavity 22 and the side cavity 21, so as to provide all the blower efficiency to the side suction inlet 201; when the smoke sensor 50 detects the escape of cooking fumes above the smoke baffle 30, it indicates that the cooking fume flow is large at this time, and the flow dividing plate 40 is controlled to turn backward to open the communication port between the top cavity 22 and the side cavity 21, so as to provide the blower efficiency to both the side suction inlet 201 and the top suction inlet 202 at the same time, so that the escaped cooking fumes are sucked in from the top suction inlet 202.

[0044] In addition, the top and side dual-suction range hood 1 of the present application can also adjust the turning angle of the flow dividing plate 40 based on the cooking fume concentration detected by the smoke sensor 50, so as to better improve the smoke suction effect.

[0045] Exemplarily, as Figure 2 、 Figure 3 and Figure 5As shown, the diverter plate 40 is rotatably connected to the front wall of the side cavity 21 at the intersection with the bottom wall of the top cavity 22. In this way, when the diverter plate 40 is flipped forward to abut against the top wall of the top cavity 22, the diverter plate 40 can close the communication port between the top cavity 22 and the side cavity 21, so that the passage between the top smoke inlet 202 and the fan box 10 is blocked, while the passage between the side smoke inlet 201 and the fan box 10 is connected; when the diverter plate 40 is flipped backward to move away from the top wall of the top cavity 22, the diverter plate 40 can open The connecting opening between the top cavity 22 and the side cavity 21 enables the passages between the top smoke inlet 202 and the side smoke inlet 201 and the fan box 10 to be connected; and when the diverter plate 40 is further flipped backward to abut against the rear wall of the side cavity 21, the diverter plate 40 can block the passage between the side smoke inlet 201 and the fan box 10, while the passage between the top smoke inlet 202 and the fan box 10 is opened.

[0046] Alternatively, if Figure 2 As shown, the width W of the diverter plate 40 is greater than the spacing S1 between the bottom wall and the top wall of the top cavity 22 on the front wall of the side cavity 21, so as to ensure that the diverter plate 40 can completely close the connecting port between the top cavity 22 and the side cavity 21, and better block the passage between the top smoke inlet 202 and the fan box 10.

[0047] Alternatively, if Figure 5 As shown, the width W of the diverter plate 40 is equal to the distance S2 between the front wall and the rear wall of the side cavity 21 on the plane where the bottom wall of the top cavity 22 is located, so that when the diverter plate 40 abuts against the rear wall of the side cavity 21 to block the passage between the side smoke inlet 201 and the fan box 10, the diverter plate 40 is prevented from blocking the flow path of oil smoke flowing through the top cavity 22 to the fan box 10, ensuring that the passage between the top smoke inlet 202 and the fan box 10 is fully opened.

[0048] It is worth noting that since when the top-side double-suction range hood 1 is in the high-pot cooking mode, the smoke baffle 30 will inevitably have a gap when closing the side smoke inlet 201; therefore, if the diverter plate 40 is still in the double-suction diversion state, or the diverter plate 40 is in the top-suction diversion state, but the diverter plate 40 fails to completely block the passage between the side smoke inlet 201 and the fan box 10, then the gap between the smoke baffle 30 and the side cavity 21 will have gas flowing through at high speed, causing a whistling sound problem.

[0049] In order to solve this problem, Figure 3 and Figure 5As shown, the flow splitter 40 of the present application may include a rigid plate body 41 rotatably connected to the front wall of the side cavity 21 and a flexible seal 42 protruding from the edge of the rigid plate body 41. In this way, as Figure 5 shown, when the flow splitter 40 is in the top-suction and flow-splitting state, the flexible seal 42 is flipped backward along with the rigid plate body 41 and is pressed between the side cavity 21 and the rigid plate body 41, achieving a good sealing effect, ensuring that the flow splitter 40 can completely block the passage between the side suction inlet 201 and the blower box 10, solving the problem of whistling abnormal noise, and improving the user experience.

[0050] Optionally, as Figure 3 and Figure 5 shown, the front edge of the rigid plate body 41 is pivotally connected to the front wall of the side cavity 21; the flexible seal 42 wraps around the rear edge, left edge, and right edge of the rigid plate body 41.

[0051] It should be noted that the flexible seal 42 mentioned in the present application may be, but is not limited to, implemented as a rubber sleeve or a silicone sleeve.

[0052] In summary, in the high-pot cooking scenario, as Figure 5 shown, the rigid plate body 41 of the flow splitter 40 is flipped backward to drive the flexible seal 42 to abut against the rear wall, left wall, and right wall of the side cavity 21, causing the flexible seal 42 to be squeezed and deformed, so as to better block the passage between the side suction inlet 201 and the blower box 10. This can not only increase the negative pressure intensity at the top suction inlet 202 and improve the oil fume suction effect, but also prevent the airflow from being sucked in through the gap between the smoke baffle 30 and the side cavity 21, thereby eliminating the resulting whistling abnormal noise and improving the user experience.

[0053] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope described in this specification.

[0054] The above embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
