Optionally, the method further comprises: when the amount of the oil smoke does not reach the threshold value, the smoke guide plate is controlled to be in a withdrawing state, and the smoke guide plate in the extending state is positioned in front of the smoke guide plate in the withdrawing state.

Compared with the prior art, the technical scheme of the invention has the following advantages:

when the front panel is driven to move to the open state to remove oil smoke, under the condition of large oil smoke amount, the smoke guide plate is driven to move to the extending state to improve the smoke trapping effect of the side-suction type range hood, so that the smoke extraction effect of the side-suction type range hood is enhanced, and the purposes of timely removing oil smoke and quickly purifying the kitchen environment are achieved.

Further, the smoke guide plate can be moved to the retracted state when the front panel is in the open state. The range of the cooking volume of the user when the smoke guide is in the retracted state is greater than the range of the cooking volume of the user when the smoke guide is in the extended state. Therefore, when the smoke exhaust effect of the side-suction type range hood is not required to be enhanced through the smoke guide plate, the smoke guide plate can be driven to move to the withdrawing state, the cooking space range of a user is enlarged, the oppressive feeling to the user during cooking is relieved, and the possibility that the user collides with the smoke guide plate is reduced.

Further, the smoke guide plate can be moved to the retracted state when the front panel is in the closed state. Therefore, when the side-draft range hood does not smoke, the smoke guide plate can be driven to move to the retracted state, so that the available space range of a kitchen is enlarged, the oppressive feeling to a user is relieved, and the possibility that the user collides with the smoke guide plate is reduced.

Furthermore, the smoke guide plate in the retracted state is arranged below the front panel in a crossed manner with the front panel, and at least one part of the smoke guide plate in the retracted state is positioned behind the outer surface of the front panel. Therefore, the part of the smoke guide plate in the retracted state, which is positioned behind the outer surface, does not occupy the range of the cooking space of the user, the oppressive feeling to the user during cooking is reduced, and the possibility of collision between the user and the smoke guide plate is reduced.

Further, the smoke guide plate in the retracted state is positioned below the front panel, and is parallel to the front panel on the back side of the front panel. Or the smoke guide plate in the retracted state is positioned below the front panel, and the outer surface of the smoke guide plate and the outer surface of the front panel are positioned on the same plane. Under the two conditions, the smoke guide plate in the retracted state can not occupy the range of the cooking space of the user, so that the oppressive feeling to the user during cooking is reduced, and the possibility of collision between the user and the smoke guide plate is reduced.

Further, the side-draft range hood further comprises a fixing panel. The front panel and the fixed panel in the closed state form an interval in the height direction, and the smoke guide plate in the retracted state is exposed from the interval. Or the smoke guide plate in the retracted state is positioned behind the fixed panel. Or the front panel in the closed state, the smoke guide plate in the retracted state and the fixing panel are sequentially arranged in the height direction. Under the three conditions, the front structure of the side-suction range hood can be simple and tidy, and the side-suction range hood is easy to clean. In addition, when the cigarette guide plate in the withdrawing state is exposed from the interval between the front panel and the fixed panel, a user in front of the front panel can see the cigarette guide plate in the withdrawing state, and the cigarette guide plate plays a decorative role.

Furthermore, the smoke collecting hood or the smoke guide plate is provided with a controller and a lighting lamp. When the smoke guide plate is in a retraction state, the smoke guide plate is positioned in front of the controller and the illuminating lamp, so that the controller and the illuminating lamp are shielded by the smoke guide plate. When the smoke guide plate is in an extending state, the smoke guide plate exposes the controller and the illuminating lamp for users to use. Therefore, when the side-draught range hood does not work, the controller and the lighting lamp can be hidden through the smoke guide plate in the withdrawing state, on one hand, the controller and the lighting lamp are prevented from being polluted, and on the other hand, the external design and the structure of the whole side-draught range hood are simpler.

Furthermore, the smoke guide plate in the extending state is positioned between the front panel and the smoke inlet in the height direction of the side-suction range hood, so that the smoke guide plate in the extending state is positioned above the smoke inlet and is closest to the smoke inlet in the height direction, and the smoke extraction effect of the side-suction range hood is strongest.

Furthermore, the motion mode of the smoke guide plate is rotation or sliding along the first direction by taking a straight line parallel to the length direction of the side-suction range hood as a rotation central axis, so that the driving control of the smoke guide plate is simpler.

Further, the movement of the front panel is sliding in the second direction, so that the driving control of the front panel is simple, and the front panel does not obstruct the user regardless of whether the front panel is in the open state or the closed state.

Further, the smoke guide plate is movably arranged on the front panel and is positioned below the front panel, and the smoke guide plate moves along with the front panel when the front panel moves. Thus, when the front panel is switched between the opening state and the closing state, the smoke guide plate can move along with the front panel and can also move relative to the front panel. The front panel is driven to move to the open state, and the smoke guide plate moves to the extending state relative to the front panel, so that the smoke guide plate in the extending state can be ensured to be positioned between the front panel and the smoke inlet in the height direction of the side-suction type range hood, and the smoke guide plate can be driven and controlled to move to the extending state very simply.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

First embodiment

Fig. 1 is a perspective view of a side-suction range hood in this embodiment when a front panel is in a closed state and a smoke guide plate is in a retracted state, fig. 2 is a perspective view of a side-suction range hood in this embodiment when a front panel is in an open state and a smoke guide plate is in a retracted state, and fig. 3 is a perspective view of a side-suction range hood in this embodiment when a front panel is in an open state and a smoke guide plate is in an extended state. The dashed lines in fig. 1 to 3 illustrate the internal invisible parts of the side draft range hood.

As shown in fig. 1 to 3, the side suction type range hood of the present embodiment includes a smoke collecting hood 1 and a front panel 2 movably installed in front of the smoke collecting hood 1. In the technical scheme of the invention, the position of A in front of B means that a user is close to A and far away from B when using the side-draft range hood. The fume collecting cover 1 is provided with a fume inlet 10, and fume generated in the cooking process enters from the fume inlet 10 to be collected in the fume collecting cover 1 and flows out through the air duct 4.

In the present embodiment, a fan system (not shown) of the side draft range hood is provided in the air duct 4, and in a variation of the present embodiment, the fan system is provided in the smoke collecting hood 1. The fan system comprises an impeller and a motor for driving the impeller to rotate.

The front panel 2 is movable relative to the hood 1 to switch between open and closed states:

as shown in fig. 2 and 3, when the side-draft range hood is used for extracting oil smoke, the front panel 2 is in the open state, so that the oil smoke enters the smoke inlet 10, i.e., the smoke inlet 10 is opened.

As shown in fig. 1, when the side-draft range hood is not extracting oil smoke, the front panel 2 is in the closed state to block oil smoke from entering the smoke inlet 10, i.e., to close the smoke inlet 10.

As shown in fig. 3, the side-draft range hood further includes a smoke guide plate 3 movably disposed. The smoke guide 3 is movable to the extended state when the front panel 2 is in the open state. In the extended state, at least a part of the smoke guide plate 3 forms a brim in front of the front panel 2, and the brim is: the smoke guide 3 is at least partially located in front of the outer surface S1 of the front panel 2 and intersects the front panel 2. The eaves portion can guide the oil smoke to get into smoke inlet 10, reduces the oil smoke and leads 3 top of cigarette board to flow the possibility of scurrying to the cage cigarette effect of side suction formula lampblack absorber has been improved.

When the drive front panel 2 moves to the open state is with the oil smoke of taking away, under the great condition of oil smoke volume, move extremely through drive smoke deflector 3 the state of stretching out can improve the cage cigarette effect of side suction formula lampblack absorber to make the smoking effect reinforcing of side suction formula lampblack absorber, reached in time take away the oil smoke, purify the purpose of kitchen environment fast.

When the oil smoke amount generated in the cooking process is not large: the smoke guide plate 3 may not be driven to move to the extended state; the smoke guide plate 3 can also be driven to move to the extending state, so that the oil smoke is pumped away in time, and the kitchen environment is quickly purified.

The relative position of the extended smoke guide plate 3 and the smoke inlet 10 in the height direction of the side-suction range hood can influence the smoke extraction effect of the side-suction range hood. When the extended smoke guide plate 3 is above the smoke inlet 10 and is closer to the smoke inlet 10 in the height direction, the smoke guide plate 3 can better guide the oil smoke into the smoke inlet 10, and the possibility that the oil smoke is diffused above the oil inlet 10 is reduced, so that the smoke extraction effect of the side-suction range hood is stronger.

In this embodiment, the extended smoke guide plate 3 is located between the front panel 2 and the smoke inlet 10 in the height direction of the side-suction range hood, so that the extended smoke guide plate 3 is located above the smoke inlet 10 and is closest to the smoke inlet 10 in the height direction, and thus the side-suction range hood has the strongest smoke extraction effect.

In a modification of the present embodiment, the smoke guide 3 in the extended state is provided above and at a distance from the lower edge of the front panel 2 in the height direction, and the lower edge refers to an edge of the front panel 2 that is close to the smoke inlet 10 in the height direction. Compared with the technical scheme of the embodiment, the side-suction range hood in the scheme of the change example has slightly poorer caging effect.

The smoke guide plate 3 in the extending state forms the included angle between the eaves part and the front panel 2 can influence the cage smoke effect of the smoke guide plate 3, and further influence the smoke sucking effect of the side-suction type range hood. Research shows that when the eaves formed by the extending smoke guide plates 3 are perpendicular to the front panel 2, the smoke guide plates 3 have the best smoke-containing effect. Of course, the eaves formed by the extended smoke guide 3 and the front panel 2 may be disposed to intersect at other angles without requiring the smoke guide 3 to achieve the optimal effect of the caging.

As shown in fig. 2, in the present embodiment, the smoke guide 3 (indicated by a dotted line) can be moved to the retracted state when the front panel 2 is in the open state. The smoke guide plate 3 no longer plays a role in improving the effect of the cage cigarette in the retracted state, or the effect of improving the effect of the cage cigarette is very small. Smoke deflector 3 (shown in fig. 3) of state of stretching out is located the place ahead of smoke deflector 3 of state of withdrawing, namely, when using the side-draught range hood, smoke deflector 3 of state of stretching out is compared smoke deflector 3 of state of withdrawing is closer to the user, and smoke deflector 3 is in user's culinary art space scope is in when the state of stretching out than smoke deflector 3 user's culinary art space scope is littleer when withdrawing the state.

Thus, when the smoke exhaust effect of the side-suction range hood is not required to be enhanced through the smoke guide plate 3, the smoke guide plate 3 can be driven to move to the withdrawing state, so that the cooking space range of a user is enlarged, the oppressive feeling to the user during cooking is reduced, and the possibility of collision between the user and the smoke guide plate 3 is reduced.

Of course, in the technical solution of the present invention, under the condition that the range of the cooking space of the user is not considered, when the front panel 2 is in the open state and the smoke exhaust effect of the side-suction range hood does not need to be enhanced by the smoke guide plate 3, the smoke guide plate 3 may also be driven to move to the extended state.

As shown in fig. 1, in the present embodiment, the smoke guide 3 (indicated by a dotted line) can also be moved to the retracted state when the front panel 2 is in the closed state. Therefore, when the side-draft range hood does not smoke, the smoke guide plate 3 can be driven to move to the retracted state, so that the available space range of a kitchen is enlarged, the oppressive feeling to a user is relieved, and the possibility that the user collides with the smoke guide plate 3 is reduced.

Of course, in the solution of the invention, it is also possible to drive the smoke guide 3 to move to said extended state when the front panel 2 is in said closed state, irrespective of the available space range of the kitchen.

As shown in fig. 1 to 2, in the present embodiment, the smoke guide plate 3 in the retracted state is disposed below the front panel 2 in a crossing manner with the front panel 2, and at least a part of the smoke guide plate 3 in the retracted state is located behind the outer surface S1 of the front panel 2, so that the part of the smoke guide plate 3 in the retracted state, which is located behind the outer surface S1, does not occupy the cooking space range of the user, thereby reducing the oppressive feeling to the user during cooking, and reducing the possibility of collision between the user and the smoke guide plate 3.

Further, in the present embodiment, the entire smoke guide 3 does not protrude from the outer surface S1 of the smoke guide 3, so that the smoke guide 3 does not occupy the space cooking range of the user.

Further, in the present embodiment, the smoke guide plate 3 in the retracted state is disposed perpendicular to the front panel 2. Of course, in other embodiments, the smoke guide plate 3 and the front panel 2 in the retracted state may intersect at any other angle.

In this embodiment, the side-draft range hood further includes a fixing panel 5 fixedly installed in front of the smoke collecting hood 1, an outer surface S2 of the fixing panel 5 is located on the same plane as an outer surface S1 of the front panel 2, and the fixing panel 5 is located below the front panel 2 in a height direction of the side-draft range hood. The front panel 2 forms a space 8 in the height direction with the fixed panel 5 in the closed state.

As shown in fig. 1, when the front panel 2 is in the closed state and the smoke guide plate 3 is in the retracted state, the smoke guide plate 3 in the retracted state is exposed from the gap 8, so that the front structure of the side-suction range hood is simple and tidy, and the side-suction range hood is easy to clean. In addition, the user in front of the front panel 2 can see the smoke guide plate 3 in the retracted state, and the smoke guide plate 3 plays a decorative role.

In this embodiment, only the thickness of the smoke guide 3 in the retracted state is visible from the space 8. Of course, in other embodiments, other portions of the smoke guide 3 may be arranged to be visible from the space 8.

Referring to fig. 2 to 3, in the present embodiment, the smoke guide plate 3 moves in a rotation manner using a straight line L parallel to the length direction of the side-suction range hood as a rotation center axis, so that the driving control of the smoke guide plate 3 is simple.

Referring to fig. 2 and 3 in sequence, when the smoke guide plate 3 moves from the retracted state to the extended state, the smoke guide plate 3 rotates outward around a straight line L.

Referring to fig. 3 and 2 in sequence, when the smoke guide plate 3 moves from the extended state to the retracted state, the smoke guide plate 3 rotates inward around a straight line L.

In this embodiment, since the smoke guide plate 3 in the extended state and the smoke guide plate 3 in the retracted state are both perpendicular to the front panel 2, the smoke guide plate 3 needs to rotate 180 degrees around the straight line L when the smoke guide plate 3 is switched between the retracted state and the extended state.

Referring to fig. 1 to 3, in the present embodiment, the smoke guide plate 3 is movably mounted on the front panel 2 and located below the front panel 2, and the smoke guide plate 3 moves together when the front panel 2 moves. In this way, when the front panel 2 is switched between the open state and the closed state, the smoke guide plate 3 can move along with the front panel 2 and also move relative to the front panel 2. Move extremely through drive front panel 2 open mode, and the relative front panel 2 motion of smoke deflector 3 extremely stretch out the state, can ensure the smoke deflector 3 of stretching out the state is located between front panel 2, the smoke inlet 10 on the direction of height of side draft lampblack absorber for smoke deflector 3 moves extremely the drive control of stretching out the state is very simple.

In the present embodiment, the front panel 2 is hinged with the smoke guide 3 so that the smoke guide 3 can rotate relative to the front panel 2. In other embodiments, the smoke guide 3 can move relative to the front panel 2 by other connecting means.

In the modified example of the embodiment, the smoke guide plate 3 is movably mounted on other components such as the smoke collecting hood 1 to realize non-linkage between the smoke guide plate 3 and the front panel 2, that is, when the front panel 2 moves, the smoke guide plate 3 does not move along with the front panel 2.

In the present embodiment, the movement of the front panel 2 is sliding in the second direction X, so that the driving control of the front panel 2 is simple, and the front panel 2 does not obstruct the user no matter whether the front panel 2 is in the open state or the closed state. The second direction X is a direction from one end of the front panel 2 to the other end, and the one end and the other end are two ends of the front panel 2 in the height direction of the side-suction range hood.

Referring to fig. 1 and 2 in turn, when the front panel 2 moves from the closed state to the open state, the front panel 2 slides in the upward second direction X1.

Referring to fig. 2 and 1 in turn, when the front panel 2 moves from the open state to the closed state, the front panel 2 slides in a downward second direction X2.

It should be noted that, in the technical solution of the present invention, the moving manner of the front panel 2 should not be limited to the given embodiment.

In the present embodiment, the smoke collecting cover 1 is provided with sliding grooves (not shown) at both ends in the longitudinal direction of the side draft range hood, and both ends of the front panel 2 in the longitudinal direction are inserted into the sliding grooves and can slide in the sliding grooves. In other embodiments, the front panel 2 can be moved relative to the smoke collecting hood 1 in other ways.

In this embodiment, the side-suction range hood further includes a first driving device 6, and the first driving device 6 is used for driving the front panel 2 to move. As shown in fig. 2 to 3, the first driving device 6 is used for driving the front panel 2 to move to the open state after receiving a normal smoking instruction. As shown in fig. 1, the first driving device 6 is used for driving the front panel 2 to move to the closed state after receiving the instruction of stopping normal smoking.

In this embodiment, the manner of sending the normal smoking instruction to the first driving device 6 is as follows: and when a user triggers a control switch on the side-suction range hood, sending the normal smoking instruction to the first driving device 6. When the control switch is triggered, the side-suction range hood starts or stops smoking.

In the present embodiment, the first driving device 6 includes a rotating motor provided on the smoke collecting hood 1 and a transmission device connected to the front panel 2 and configured to convert a rotational motion output from the rotating motor into a linear motion, thereby driving the front panel 2 to move in the second direction X to switch between the closed state and the open state.

In a modification of the present embodiment, the first driving device 6 is constituted by a linear motor connected to the front panel 2. When the linear motor operates, it drives the front panel 2 to move in the second direction X to switch between the closed state and the open state.

It should be noted that, in the technical solution of the present invention, the configuration of the first driving device 6 is not limited to the given embodiment, and it can be adjusted accordingly according to the moving manner of the front panel 2.

In a variant of this embodiment, the first drive means 6 is absent from the side-draft range hood, in which case the movement of the front panel 2 to said open state, said closed state can be controlled manually.

In this embodiment, the side-draft range hood further includes a second driving device 7, and the second driving device 7 is used for driving the smoke guide plate 3 to move. As shown in fig. 3, the second driving device 7 is used for driving the smoke guide plate 3 to move to the extended state after receiving the strong smoke exhaust command, so as to improve the smoke exhaust effect of the side-suction range hood when the amount of generated oil smoke is large in cooking, thereby rapidly purifying the kitchen environment.

As shown in fig. 2, in the present embodiment, the second driving device 7 is further configured to drive the smoke guide plate 3 to move to the retracted state after receiving the instruction to stop the powerful smoking, so that when the smoke guide plate 3 is not needed to enhance the smoking effect of the side-draught range hood, the smoke guide plate 3 can be controlled to be in the retracted state to increase the range of the cooking space of the user, reduce the oppressive feeling to the user during cooking, and reduce the possibility of collision between the user and the smoke guide plate 3.

As shown in fig. 3, in the modified example of this embodiment, the second driving device 7 is used for driving the smoke guide plate 3 to move to the extended state after receiving a normal smoke exhaust instruction, so that when the side-suction range hood smokes, no matter how much the amount of smoke is generated in cooking, the smoke guide plate 3 is always kept in the extended state to ensure that the side-suction range hood always has a good smoke exhaust effect, and the kitchen environment can be always purified to the maximum extent. In a modified example, the smoke guide plate 3 may be driven to move until the extended state is reached after the front panel 2 is moved to the open state, or the smoke guide plate 3 may be driven to move while the front panel 2 is driven to move to the open state.

In the present embodiment, the manner of sending the strong smoking command and the strong smoking cessation command to the second driving device 7 is as follows: and arranging a detection device for detecting the amount of oil smoke generated by cooking, wherein when the detection device judges that the current amount of the oil smoke reaches or exceeds a preset threshold value, the detection device sends the powerful smoke exhausting instruction to the second driving device 7, and otherwise, the detection device sends the powerful smoke exhausting stopping instruction to the second driving device 7.

In a modification of the present embodiment, the manner of sending the strong smoking instruction and the strong smoking cessation instruction to the second driving device 7 is: and arranging a switch on the side-suction range hood, triggering the switch to send the powerful smoke-pumping instruction to the second driving device 7 when a user feels that the amount of the generated oil smoke is large, and triggering the switch to send the powerful smoke-pumping stopping instruction to the second driving device 7 when the user feels that the amount of the generated oil smoke is not large.

In this embodiment, the manner of sending the normal smoking instruction to the second driving device 7 is the same as that of the first driving device 6, and is not described herein again.

In the present embodiment, the second driving device 7 includes a rotating motor provided on the smoke collecting hood 1, and the rotating motor is connected to the smoke guide plate 3 so as to drive the smoke guide plate 3 to rotate about the straight line L to the extended state and the retracted state.
