Detailed Description

The side-suction range hood in the prior art has a large volume, and one reason of the side-suction range hood is that a panel at the position of a side-suction air inlet and the rising direction of oil smoke are obliquely arranged to take a large space in order to achieve a smoke gathering effect. And if the panel of the air inlet is set to be parallel to the rising direction of the oil smoke, the effect of gathering the smoke is difficult to play, thereby influencing the smoke extraction effect.

The invention provides a machine shell component of a range hood, wherein when the machine shell component is in a working state, a smoke inlet part is switched in position and at least partially extends out of the machine shell; the deflector can also be switched from a position closing the air inlet to a position opening said air inlet. Thereby make the guide plate extend the certain distance forward for the casing, and the guide plate position is adjustable to the top of cooking utensils, has improved and has held together the cigarette effect, and then has improved smoking efficiency.

In addition, when the range hood is in a non-working state, the guide plate seals the air inlet, and the smoke inlet part does not extend out of the shell, so that the range hood is small in size.

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

Referring to fig. 1 to fig. 3, structural diagrams of different positions of an embodiment of a housing assembly of a range hood of the present invention in an operating state are shown. This implement range hood's casing subassembly includes:

a casing 10, wherein the casing 10 is a housing for accommodating the blower and also provides an accommodating space for other components of the casing assembly. The housing 10 is a metal plate.

And a smoke inlet 11 located at one side of the casing 10 close to the cooking bench, for guiding the oil smoke to enter the casing 10. The smoke inlet 11 includes an air inlet 112 and a baffle 111.

The air inlet 112 is a passage through which the oil smoke enters the interior of the housing 10, in this embodiment, the air inlet 112 is opened in the panel, and the shape of the air inlet 112 is rectangular.

The smoke inlet 11 further includes a guide plate 111 for collecting smoke of the oil smoke rising from the cooking bench.

The smoke intake part 11 is a position-adjustable structure, and specifically, the smoke intake part 11 is adapted to be switched between a first position P1 and a second position P2. As shown in fig. 1, when the smoke inlet 11 is located at the first position P1, the smoke inlet 11 seals the casing 10. As shown in fig. 2, when the first position P1 is switched to the second position P2, the smoke inlet 11 extends from the inside of the casing 10, so that the guide plate 111 extends forward (toward the top of the kitchen range) relative to the casing 10 for a certain distance, so as to improve the smoke collecting effect.

The deflector 111 is also of a position adjustable type, in particular, the deflector 111 is arranged such that the deflector 111 is adapted to be switched between a third position P3 and a fourth position P4. Specifically, as shown in fig. 2, when the baffle 111 is in the third position P3, the baffle 111 closes the air inlet 112. As shown in fig. 3, when the baffle 111 is in the fourth position P4, the intake vent 112 is open, and the baffle 111 is adapted to direct airflow into the intake vent 112. When the guide plate 111 is located at the fourth position P4, in order to open the air inlet 112, the guide plate 111 may further extend forward (toward a direction close to the cooking bench) relative to the air inlet 112, so as to make the guide plate 111 closer to a position where smoke on the cooking bench rises, thereby optimizing a smoke collecting effect.

In practical application, when the range hood is opened to prepare for smoking, the smoke inlet 11 is switched from the first position P1 to the second position P2 to open the panel of the casing, then the guide plate 111 is switched from the third position P3 to the fourth position P4 to open the air inlet 112, and finally the fan in the casing 10 is controlled to start; when the range hood is used, the fan is turned off, the guide plate 111 is switched from the fourth position P4 to the third position P3 to seal the air inlet 112, and finally the rear smoke inlet part is switched from the second position P2 to the first position P1 to seal the casing 10. That is, the smoke inlet 11 and the air deflector 111 extend forward in the operating state of the range hood, and the smoke inlet 11 seals the housing 10 and the air deflector 111 seals the air inlet 112 in the non-operating state, so that the overall structure is compact and occupies a small space.

In this embodiment, when the smoke inlet 11 is at the first position P1 and the flow guide plate 111 is at the third position P3, the whole casing assembly is a rectangular parallelepiped structure. The cuboid structure is compact, is suitable for being hung on a wall, does not occupy space and is not easy to have the problem of head collision.

Referring to fig. 1 and 2, in the present embodiment, when the smoke inlet 11 is switched from the first position P1 to the second position P2, the smoke inlet 11 rotates around a rotation axis at the bottom thereof, so that the top region of the smoke inlet 11 protrudes from the inside of the housing 10.

The position switching of the smoke inlet part 11 is realized by a rotating mode, and the structure is simple and easy to realize. In other embodiments, the smoke inlet 11 may extend from the housing in other manners, for example, the smoke inlet 11 may extend from the housing 10 in a manner of integral translation. In this embodiment, the bottom of the smoke inlet 11 is movably connected to the casing 10; when switching from the first position P1 to the second position P2, the smoke inlet 11 rotates about the joint as a rotation axis. For example, the bottom of the smoke inlet 11 is movably connected to the casing 10 (for example, a side wall of the casing 10) by a screw; when switching from the first position P1 to the second position, the smoke inlet 11 rotates about the screw.

The connection is realized by adopting a screw mode, the structure is simple, and the fixation is firm. In other embodiments, the bottom of the smoke inlet 11 may also be movably connected to the casing 10 through a hinge structure.

Referring collectively to fig. 4 and 5, there are shown schematic views of the chassis assembly of fig. 1 taken along section lines AA 'and BB', respectively.

In this embodiment, when the first position P1 is switched to the second position P2, the smoke inlet 11 is adapted to be rotated by the first driving mechanism 12.

The first drive mechanism 12 includes: an arc chute 121 disposed in the side wall of the housing 10, and a support arm 122 fixed to the inner wall of the smoke inlet 11.

The supporting arm 122 is arranged parallel to the side wall, a sliding block 123 is arranged on the surface of the supporting arm 122 facing the side wall, and the sliding block 123 is suitable for moving in the arc chute 121 to drive the smoke inlet part 11 to rotate around the bottom rotating shaft, so that the smoke inlet part 11 is switched between a first position P1 and a second position P2.

The support arm 122 is matched with the arc chute 121 in position, and the arrangement of the two positions in the matched meaning enables the sliding block 123 of the support arm 122 to move in the arc chute 121. In this embodiment, in order to enable the deflector 111 to have the maximum translational position when the smoke inlet 11 is switched from the first position P1 to the second position P2, the smoke inlet 11 needs to have a large radius of rotation, so the support arm 122 is disposed at a position flush with the top end of the smoke inlet 11, and accordingly, the arc chute 121 is disposed at a position near the top of the side wall of the housing.

The first drive mechanism 12 further includes: and the motor 124 is connected with the supporting arm 122 and is suitable for driving the supporting arm 122 to enable the sliding block 123 to move in the circular arc sliding chute 121. Specifically, the fixed end of the motor 124 is movably connected (for example, connected by a screw) to the side wall of the housing 10, the extendable end of the motor 124 is connected to the supporting arm 122, and the extendable end of the motor 124 drives the supporting arm 122 to move, so that the sliding block 123 moves in the arc chute 121.

The motor 124 can electrically control the smoke inlet 11 to switch between the first position P1 and the second position P2, which can provide better use feeling for consumers.

Specifically, the electric machine 124 may be a motor or a cylinder.

Note that, in order to prevent positional deviation when the smoke intake portion 11 is switched between the first position P1 and the second position P2. The first driving mechanism 12 is further provided with a component capable of limiting.

Specifically, the arc chute 121 and the slider 123 are configured to: when the smoke inlet 11 is at the first position P1, the sliding block 123 is located at the end of the circular arc chute 121, so that the sliding block 123 cannot move further inward, and the smoke inlet 11 cannot rotate further into the housing 10, thereby realizing position limitation during switching of the smoke inlet 11 from the second position P2 to the first position P1.

Referring to fig. 6, a close-up view of the opening of the circular arc chute of fig. 1 is shown.

The opening end of the arc chute 121 is also provided with a limiting mechanism 125, and when the smoke inlet 11 is at the second position P2, the slide block 123 is at the limiting position of the limiting mechanism 125. In the limit position, the limit mechanism 125 prevents the slider 123 from moving further outward, and the smoke inlet 11 does not rotate in a direction away from the housing 10, so that position limitation is achieved during switching of the smoke inlet 11 from the first position P1 to the second position P2.

In particular, the limiting mechanism 125 may be a mechanical limiting component, such as: the limiting mechanism 125 is a limiting projection adapted to block the movement of the sliding block 123.

Alternatively, the limiting mechanism 125 may be an electrical limiting component, such as: the position limiting mechanism 125 is a sensor adapted to sense the position of the sliding block 123. When the sliding block 123 is sensed to reach the limit position, the motor 124 is controlled to stop working.

With continued reference to fig. 2 and 3, when the smoke inlet 11 is switched to the second position P2, the baffle 111 starts to switch from the third position P3 to the fourth position P4, so as to switch from a state of sealing the air inlet 122 to a state of opening the air inlet 122, so as to guide the airflow into the air inlet 122. Before the guide plate 111 position switches, the smoke inlet part 11 extends a certain distance to the outer of the casing, and the switching position of the guide plate 111 can be adjusted according to the position of the cooking bench to adjust the position where the smoke collecting effect is optimal, so that the volume of the range hood is small, and the smoke sucking effect is better than that of the traditional side-suction range hood.

In this embodiment, the deflector 111 rotates around a rotating shaft at the top thereof to switch from the third position P3 to the fourth position P4. The top of the baffle 111 is movably fixed at the air inlet 122, so that the baffle 111 has the maximum rotation radius when rotating. In other embodiments, the deflector 111 may be switched in position in other ways. Specifically, the top of the air guide plate 111 is movably connected to the air inlet 112; when the switch is made from the third position P3 to the fourth position P4, the baffle 111 rotates about the joint as a rotation axis. In this embodiment, the top of the baffle 111 is movably connected to the air inlet 122 through a screw; when the third position P3 is switched to the fourth position P4, the baffle 111 rotates around the screw to open the air inlet 122.

Referring collectively to FIG. 5, there is shown a schematic view of the housing assembly of FIG. 1 taken along line BB'. In this embodiment, when the switch is switched from the third position P3 to the fourth position P4, the baffle 111 is adapted to rotate under the driving of the second driving mechanism 13.

As shown in fig. 5, in the present embodiment, the number of the supporting arms 122 in the first driving mechanism 12 is two, and the two supporting arms are respectively disposed corresponding to the two side walls of the casing 10; the second drive mechanism 12 includes:

a cross beam 131 between the two support arms 122; the motor 132 fixed to the cross beam 131 and connected to the inner wall (the side facing the cabinet) of the baffle 111 is adapted to drive the baffle 111 to rotate around a rotating shaft at the top of the baffle 111 when the baffle 111 is switched from the third position P3 to the fourth position P4.

In this embodiment, one end (fixed end) of the motor 132 is fixed to the center of the beam 131, and the other end (extended end) is connected to the center of the baffle 111. Thus, when the guide plate 111 is switched from the third position P3 to the fourth position P4, the central position of the guide plate 111 is stressed, so the stress is uniform, and the rotation process is stable.

Specifically, the electric machine 124 may be a motor or a cylinder.

Correspondingly, the invention also provides a range hood which comprises the machine shell assembly. The range hood of the invention reduces the volume while solving the problem of head collision.
