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.
Fig. 1 is a perspective view of a side-suction type range hood in an embodiment of the present invention with a front panel in a closed state and a movable smoke guide plate in a retracted state, fig. 2 is a perspective view of a side-suction type range hood in an embodiment of the present invention with a front panel in an open state and a movable smoke guide plate in a retracted state, fig. 3 is a perspective view of a side-suction type range hood in an embodiment of the present invention with a front panel in an open state and a movable smoke guide plate in an extended state, and fig. 4 is a side view of the side-suction type range hood shown in fig. 3.
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 the side-draft range hood is used. 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 type hood is provided in the air duct 4, and in a variation of the present embodiment, the fan system is provided in the hood 1. The fan system comprises an impeller and a motor for driving the impeller to rotate.
The front panel 2 can move relative to the fume collecting hood 1 to switch between an open state and a closed state:
as shown in fig. 2 and 3, when the side suction type exhaust hood exhausts the oil smoke, the front panel 2 is in the open state, so that the oil smoke enters the smoke inlet 10, that is, the smoke inlet 10 is opened.
As shown in fig. 1, when the side suction type exhaust 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 to 4, the side-suction type range hood further includes a movable smoke guide plate 3, and the movable smoke guide plate 3 can move to an extended state relative to the front panel 2. In the extended state, the front panel 2 is in the open state, and at least a portion of the movable smoke guide 3 forms an eaves at the upper end of the front panel 2, the eaves being located in front of the outer surface S1 of the front panel 2. The eaves can block oil smoke from flowing to the upper end of the movable smoke guide plate 3 and guide the oil smoke to enter the smoke inlet 10 (as shown by a dotted arrow in fig. 4), so that the smoke caging effect of the side-suction type range hood is improved. In the technical scheme of the invention, the upper end refers to the end, far away from the oil inlet 10, of the front panel 2 in the height direction Z of the side-suction type range hood. In the technical solutions of the present invention, the terms "a" and "an" merely denote articles, and do not denote quantities.
In the technical solution of the present invention, the formation of the eave at the upper end of the front panel 2 includes the following three cases:
in case one, as shown in fig. 4, the rear end 31 of the eaves is not lower than the front panel 2, and the front end 30 of the eaves is higher than the front panel 2. In the present invention, the front end 30 is an end of the side-suction type hood closer to the user in the front-rear direction Y, and the rear end 31 is an end of the side-suction type hood farther from the user in the front-rear direction Y. In the present invention, higher than the front panel 2 means higher than the upper end of the front panel 2, and lower than the front panel 2 means lower than the upper end of the front panel 2.
In a second case, as shown in fig. 5, the front end 30 and the rear end 31 of the eaves are flush with the upper end of the front panel 2.
In case three, as shown in fig. 6, the rear end 31 of the eaves is not lower than the front panel 2, and the front end 30 of the eaves is lower than the front panel 2.
When 2 motion to the open mode in order to take away the oil smoke in the drive front panel, under the great condition of oil smoke volume, move to the state of stretching out through drive activity smoke deflector 3 and can form eaves portion, eaves portion can block that the oil smoke flows to the top of activity smoke deflector 3 and scurries to guide the oil smoke to get into smoke inlet 10, thereby can improve the cage cigarette effect of side-suction formula smoke ventilator, make the smoke extraction effect reinforcing of side-suction formula smoke ventilator, reached in time take away the oil smoke, purify the purpose of kitchen environment fast. Because eaves portion forms in the upper end of front panel 2, and there is the certain distance with oil inlet 10 on the direction of height Z of side-draught range hood, so eaves portion is far away apart from cooking utensil on direction of height Z, can not occupy the space around the cooking utensil, and in addition, the eaves portion that is in the higher position during the culinary art falls into the possibility of user visual range and reduces, has reduced the oppression sense that leads to the fact the user, has also reduced the possibility that user and activity smoke deflector 3 bump.
In the preferred embodiment of the invention, the eaves formed by the movable smoke guide 3 in the extended state, and the front panel 2, are in the second position, because: the projected area of the brim part in the height direction Z is the largest, and the largest oil smoke can be covered, so that the range hood has the best oil smoke covering capacity.
When the oil smoke amount generated in the cooking process is not large: the movable smoke guide plate 3 can not be driven to move to the extending state; the movable 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.
In this embodiment the entire movable smoke guide 3 forms the eaves. In a modification of the present embodiment, a part of the movable smoke guide 3 may form the brim portion in front of the front panel 2, and another part may be located behind the front panel 2.
As shown in fig. 2, in the present embodiment, when the front panel 2 is in the open state, the movable smoke guide 3 can move to a retracted state with respect to the front panel 2. The movable smoke guide plate 3 in the retracted state the eaves disappear and no longer play a role in improving the effect of the cigarette cage. The movable smoke guide plate 3 (shown in fig. 3) in the extending state is positioned in front of the movable smoke guide plate 3 in the retracting state, namely, when the side-suction type range hood is used, the movable smoke guide plate 3 in the extending state is closer to a user than the movable smoke guide plate 3 in the retracting state, and the cooking space range of the user is smaller than that of the movable smoke guide plate 3 in the retracting state through the movable smoke guide plate 3 in the extending state.
Thus, when the smoke exhaust effect of the side-suction type smoke exhaust ventilator is not required to be enhanced through the movable smoke guide plate 3, the movable smoke guide plate 3 can be driven to move to the retraction 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 movable smoke guide plate 3 is reduced.
Of course, in the technical solution of the present invention, when the front panel 2 is in the open state and the smoke exhaust effect of the side-suction type smoke exhaust ventilator does not need to be enhanced by the movable smoke guide plate 3 without considering the range of the cooking space of the user, the movable smoke guide plate 3 may also be driven to move to the extended state.
In the present embodiment, as shown in fig. 1, the movable smoke guide 3 can also move to the retracted state with respect to the front panel 2 when the front panel 2 is in the closed state. Therefore, when the side-suction type smoke exhaust ventilator does not smoke, the movable smoke guide plate 3 can be driven to move to the retraction 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 movable smoke guide plate 3 is reduced.
Of course, in the solution of the invention, it is also possible to drive the movable 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.
Referring to fig. 1 to 2, in the present embodiment, the outer surface S2 of the movable smoke guide plate 3 in the retracted state and the outer surface S1 of the front panel 2 in the closed state are both planar, and the outer surface S2 of the movable smoke guide plate 3 in the retracted state and the outer surface S1 of the front panel 2 in the closed state are located on the same plane and are adjacent to each other in the height direction Z, so that the front structure of the side-suction range hood is simple and neat, and the side-suction range hood is also easy to clean.
It should be noted that, in the technical solution of the present invention, the relative positional relationship between the outer surface S2 of the movable smoke guide 3 in the retracted state and the outer surface S1 of the front panel 2 in the closed state should not be limited to the given embodiment. For example, in a modification, the outer surface S2 of the movable smoke guide 3 in the retracted state and the outer surface S1 of the front panel 2 in the closed state are disposed opposite to each other in the front-rear direction Y.
In the technical solution of the present invention, the shapes of the outer surface S2 of the movable smoke guide 3 in the retracted state and the outer surface S1 of the front panel 2 in the closed state are not limited to the present embodiment. For example, in a modification, at least one of the outer surface S2 of the movable smoke guide plate 3 in the retracted state and the outer surface S1 of the front panel 2 in the closed state is a curved surface, and the curved surface are smoothly joined in the height direction Z, so that the outer surface S2 of the movable smoke guide plate 3 in the retracted state and the outer surface S1 of the front panel 2 in the closed state can naturally transit at the joining position without abrupt change. In a specific embodiment, the curved surface is an arc surface, and the outer surface S2 of the movable smoke guide plate 3 in the retracted state and the outer surface S1 of the front panel 2 in the closed state are wave-shaped surfaces as a whole.
In the present embodiment, the side draft type exhaust hood further includes a fixed panel 5 fixedly installed in front of the smoke collecting hood 1, an outer surface S3 of the fixed panel 5, an outer surface S2 of the retracted movable smoke guide 3 and an outer surface S1 of the closed front panel 2 are located on the same plane, and in the height direction Z, an outer surface S1 of the closed front panel 2 is located between an outer surface S3 of the fixed panel 5 and an outer surface S2 of the retracted movable smoke guide 3.
As shown in fig. 3, in the present embodiment, the movable smoke guide 3 is rotatably connected to the front panel 2, and the movable smoke guide 3 is moved to the extended state and the retracted state by rotation about a straight line L parallel to the longitudinal direction X of the side-suction type hood as a rotation center axis, so that the driving control of the movable smoke guide 3 is simple.
Referring to fig. 2 and 3 in turn, when the movable smoke guide 3 moves from the retracted state to the extended state, the movable smoke guide 3 rotates outward about a straight line L.
Referring to fig. 3 and 2 in turn, when the movable smoke guide 3 moves from the extended state to the retracted state, the movable smoke guide 3 rotates inward about a straight line L.
In the present embodiment, the front panel 2 is hinged to the movable smoke guide 3 so that the movable smoke guide 3 can rotate relative to the front panel 2. In other embodiments, the movable smoke guide plate 3 can move relative to the front panel 2 by other connecting means.
In the present embodiment, the front panel 2 moves linearly, so that the driving control of the front panel 2 is simple, and the front panel 2 does not obstruct the user no matter the front panel 2 is in the open state or the closed state. The direction of the linear movement 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 Z.
Referring to fig. 1 and 2 in sequence, when the front panel 2 moves from the closed state to the open state, the front panel 2 moves linearly upward, and in the technical solution of the present invention, the upward movement refers to movement in a direction approaching the air duct 4 in the height direction Z. When the front panel 2 moves upwards, the movable smoke guide plate 3 can move upwards along with the front panel 2, then, the movable smoke guide plate 3 is driven to rotate relative to the front panel 2, and the movable smoke guide plate 3 can be controlled to retract and switch to the extending state.
Referring to fig. 2 and 1 in sequence, when the front panel 2 moves from the open state to the closed state, the front panel 2 moves linearly downward. When the front panel 2 moves down, the movable smoke guide plate 3 can move down along with the front panel 2, and then the movable smoke guide plate 3 can be controlled to rotate relative to the front panel 2 by driving the movable smoke guide plate 3 to rotate, so that the extending state is switched to the retracting state.
In the present embodiment, the smoke collecting hood 1 is provided with sliding grooves (not shown) at both ends in the longitudinal direction X of the side-suction type range hood, and both ends of the front panel 2 and the movable smoke guide plate 3 in the longitudinal direction X are inserted into the sliding grooves and can slide in the sliding grooves. When the front panel 2 moves upwards to the movable smoke guide plate 3 to separate from the sliding rail, the movable smoke guide plate 3 can rotate relative to the front panel 2 to move to the extending state, so that the cigarette cage effect is improved. When the caging is finished, the movable smoke guide plate 3 can rotate in the opposite direction relative to the front panel 2 to move from the extended state to the retracted state, and then the front panel 2 can move downwards together with the movable smoke guide plate 3.
It should be noted that, in the technical solution of the present invention, the implementation manner of switching the front panel 2 between the open state and the closed state should not be limited to the given embodiment. For example, in a modification, the front panel 2 may be switched between the open state and the closed state by rotation. Alternatively, in another modification, the front panel 2 may be switched between the open state and the closed state by moving linearly in the longitudinal direction X.

In the present embodiment, the driving device 6 is also used for: when receiving a powerful smoke exhaust instruction, the movable smoke guide plate 3 is driven to move to the extending state, so that the smoke exhaust effect of the side-suction type smoke exhaust ventilator is improved when the amount of smoke generated in cooking is large, and the kitchen environment is quickly purified; when receiving to stop powerful smoking instruction, drive activity smoke deflector 3 and move to the state of withdrawing, so, when need not to strengthen the smoking effect of side draft smoke ventilator through activity smoke deflector 3, can control activity smoke deflector 3 and be in the state of withdrawing to increase user's culinary art spatial dimension alleviates the sense of oppression that causes the user during the culinary art, also reduces the possibility that user and activity smoke deflector 3 bump thereupon. The intelligent driving control of the movable smoke guide plate 3 can be realized through the driving device 6.
In the present embodiment, the manner of sending the strong smoking instruction and the strong smoking cessation instruction to the driving device 6 is: 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 smoking instruction to the driving device 6, and otherwise, the detection device sends the powerful smoking stopping instruction to the driving device 6.
In a modification of the present embodiment, the manner of sending the strong smoking instruction and the strong smoking cessation instruction to the driving device 6 is: and a switch is arranged on the side-suction type range hood, when a user feels that the amount of the generated oil smoke is large, the switch is triggered to send the powerful smoke exhausting instruction to the driving device 6, and when the user feels that the amount of the generated oil smoke is not large, the switch is triggered to send the powerful smoke exhausting stopping instruction to the driving device 6.
In this embodiment, the driving means 6 is adapted to drive the movable smoke guide 3 from the retracted state to the extended state after driving the front panel 2 to the open state. The movable smoke guide 3 may be driven from the retracted state to the extended state as soon as the front panel 2 moves to the open state, or the movable smoke guide 3 may be driven from the retracted state to the extended state after waiting for a certain period of time after the front panel 2 moves to the open state.
In this embodiment, the driving means 6 is adapted to drive the front panel 2 from the open state to the closed state after driving the movable smoke guide 3 to the retracted state. The front panel 2 may be driven to move from the open state to the closed state as soon as the movable smoke guide 3 moves to the retracted state, or the front panel 2 may be driven to move from the open state to the closed state after waiting for a certain period of time after the movable smoke guide 3 moves to the retracted state.
In the present embodiment, the driving device 6 includes a rotating motor provided on the smoke collecting hood 1, and a first transmission device and a second transmission device, the first transmission device being connected to the front panel 2 and being configured to convert a rotational motion output from the rotating motor into a linear motion, thereby driving the front panel 2 to move linearly to switch between the closed state and the open state. The second transmission device is connected with the movable smoke guide plate 3 and drives the movable smoke guide plate 3 to rotate, so that the second transmission device is switched between the extending state and the retracting state.
In a modification of the present embodiment, the driving device 6 includes a linear motor and a rotary motor provided on the smoke collecting hood 1. The linear motor is connected with the front panel 2, and when the linear motor works, the linear motor drives the front panel 2 to do linear movement so as to switch between the closed state and the open state. The rotary motor is connected to the movable smoke guide plate 3, and when the rotary motor operates, it drives the movable smoke guide plate 3 to rotate to switch between the extended state and the retracted state.
In the modified example of the embodiment, the driving device 6 is not arranged in the side-suction type range hood, in this case, the front panel 2 and the movable smoke guide plate 3 can be controlled to move manually.

When the movable smoke guide plate 3 is not linked with the front panel 2, other changes can be made on the switching implementation mode of the movable smoke guide plate 3 between the extending state and the retracting state. For example, in a modified example, the movable smoke guide 3 is moved in a linear manner in the front-rear direction Y, so that the driving control of the movable smoke guide 3 is simple. When the movable smoke guide 3 moves from the retracted state to the extended state, the movable smoke guide 3 moves in the forward front-rear direction Y. When the movable smoke guide 3 moves from the extended state to the retracted state, the movable smoke guide 3 moves in the backward front-rear direction Y.
