Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

First, the flow of the flue gas (airflow) indicated by arrows in fig. 3, 7, and 11 to 13 is described.

As shown in fig. 1 to 16, the present embodiment provides a fume collecting hood structure, which includes a fume collecting hood 100, a first baffle 110 and a second baffle 120, wherein the first baffle 110 and the second baffle 120 are both connected between a front side wall and a rear side wall of the fume collecting hood 100, the first baffle 110 and the second baffle 120 are sequentially arranged along a fume intake direction of the fume collecting hood 100, and the first baffle 110 and/or the second baffle 120 can move along a left-right direction of the fume collecting hood 100, so that the first baffle 110 and the second baffle 120 can be switched between a first state and a second state. In the first state, the first baffle 110 and the second baffle 120 are stacked in the smoke collection hood 100 in the smoke intake direction; in the second state, a smoke inlet gap is formed between the first baffle 110 and the second baffle 120 in the left-right direction of the smoke collecting hood 100.

It is understood that the upper, lower, left, right, front and rear orientations defined in the present embodiment are defined as the orientations of the range hood including the smoke collecting hood structure in the use state. Specifically, a cooking person stands facing the range hood, the front-back direction of the cooking person is the front-back direction of the range hood and the smoke collecting hood 100, the left-right direction of the cooking person is the left-right direction of the range hood and the smoke collecting hood 100, and the up-down direction of the cooking person is approximately the up-down direction of the range hood and the smoke collecting hood 100. When the fume collecting hood 100 is arranged up and down, the fume inlet direction of the fume collecting hood 100 is from bottom to top; when the fume collecting hood 100 has an inclined angle toward the cooking side, as can be seen in fig. 3, the fume intake direction of the fume collecting hood 100 is a direction from the front lower side to the rear upper side, i.e., a direction substantially perpendicular to the plane of the fume intake of the fume collecting hood 100.

Wherein each of the first baffle 110 and the second baffle 120 may be one or more. When the first baffle 110 and the second baffle 120 are plural, there are various arrangements of the first baffle 110 and the second baffle 120, for example, the first baffle 110 and the second baffle 120 may be alternately arranged along the left-right direction of the smoke collecting hood 100, and for example, plural first baffles 110 are adjacently arranged in sequence, and plural second baffles 120 are adjacently arranged in sequence. The present embodiment mainly takes the first baffle 110 and the second baffle 120 as an example.

The fume collecting hood structure of the present embodiment can realize various fume intake modes of the fume collecting hood 100 by the movement of the first baffle 110 and the second baffle 120. In the first state, the first baffle 110 and the second baffle 120 are stacked in the smoke intake direction of the smoke collecting hood 100, that is, the first baffle 110 and the second baffle 120 do not have a smoke intake gap in the left-right direction. At this time, there may be a plurality of smoke input states depending on the positions of the first barrier 110 and the second barrier 120. For example, the first baffle 110 and the second baffle 120 are located at one side of the fume collecting hood 100 in the left-right direction, and the oil smoke can enter the fume collecting cavity through the other side of the fume collecting hood 100 in the left-right direction, so that the smoke collecting cavity can be specifically applied to the condition that a cooker at one side is opened; for another example, the first baffle 110 and the second baffle 120 are located in the middle of the smoke collecting hood 100 in the left-right direction, and the oil smoke can enter the smoke collecting cavity through the edges of the first baffle 110 and the second baffle 120, which can be applied to the case that the cookers on both sides are opened simultaneously. In the second state, the first baffle 110 and the second baffle 120 form a smoke inlet gap in the left-right direction of the smoke collecting hood 100, and at this time, the smoke can enter the smoke collecting chamber of the smoke collecting hood 100 from the smoke inlet gap between the first baffle 110 and the second baffle 120. At this time, there may be a plurality of smoke intake states depending on the positions of the first shutter 110 and the second shutter 120. For example, the first baffle 110 and the second baffle 120 are arranged at intervals with the left side wall and the right side wall of the fume collecting hood 100 at the moment, so that the requirement of simultaneously opening and using a three-hole stove or a multi-hole stove can be met; for another example, one of the first baffle 110 and the second baffle 120 is connected with the left side wall of the smoke collecting hood 100, and the other is connected with the right side wall of the smoke collecting hood 100, so that the condition that the middle stove is opened and used independently can be met.

It is thus clear that this embodiment collection petticoat pipe structure can have multiple cigarette mode of advancing to can select suitable cigarette mode of advancing according to the difference of culinary art operating mode, with the oil smoke suction effect of improving, improve user's experience and feel.

The present embodiment is mainly described by taking as an example that the first baffle 110 and the second baffle 120 are both spaced apart from the left side wall and the right side wall of the fume collecting hood 100 in the first state and the second state, that is, the movement of the first baffle 110 and the second baffle 120 can form a three-cavity fume collecting structure. In the case that most of the existing cookers are double-range openings, the first baffle 110 and the second baffle 120 of the smoke collecting hood structure of the present embodiment are usually fixed at the middle position of the smoke collecting hood 100 in the left-right direction, so as to enable double-cavity smoke inlet, as shown in fig. 1 in particular.

The fume collecting hood structure of the present embodiment may have an intermediate state, which is also fixedly maintainable, in the process of switching from the first state to the second state. In the neutral state, one of the left and right sides of the projection of the second barrier 120 on the horizontal plane is located outside the projection of the first barrier 110 on the horizontal plane, and the other of the left and right sides of the projection of the second barrier 120 on the horizontal plane is located within the range of the projection of the first barrier 110 on the horizontal plane or is connected to the edge of the projection of the first barrier 110 on the horizontal plane. This intermediate state enables the dual chamber gas flow distribution to be adjusted as desired. Specifically, fig. 9 shows a state where the right chamber is divided, the first baffle 110 is located at the middle of the smoke collecting hood 100, the second baffle 120 is moved to the left, and the left side of the second baffle 120 protrudes to the left side with respect to the first baffle 110. The right side of the second baffle 120 and the left side of the first baffle 110 may be flush in the left-right direction, i.e., the right side of the projection of the second baffle 120 on the horizontal plane is connected with the left edge of the projection of the first baffle 110 on the horizontal plane; or the right side of the second baffle 120 is still directly above the first baffle 110, i.e. the right side of the projection of the second baffle 120 in the horizontal plane is within the range of the projection of the first baffle 110 in the horizontal plane. At this time, the second baffle 120 blocks part of the left ventilation channel, so that the airflow is distributed to the right, thereby increasing the wind speed on the right and improving the smoking effect on the right. Fig. 10 shows a state of the left chamber dividing the wind, the first baffle 110 is located in the middle of the smoke collecting hood 100, the second baffle 120 moves to the right, the right side of the second baffle 120 extends to the right side relative to the first baffle 110, the left side of the second baffle 120 and the right side of the first baffle 110 can be flush in the left-right direction or the left side of the second baffle 120 is still located right above the first baffle 110, at this time, the second baffle 120 blocks part of the right ventilation channel, so that the airflow is distributed to the left, thereby increasing the wind speed on the left side and improving the smoking effect on the left side. Fig. 2 shows a double-chamber air distribution state, in which the first baffle 110 is located in the middle of the exhaust fume collecting hood 100, and the second baffle 120 is moved to the middle, so that the airflow is uniformly distributed to the left and right, and the air is uniformly supplied to the left and right chambers.

The movement of the first baffle 110 and/or the second baffle 120 of the smoke collecting hood structure of the present embodiment has various forms, such as a manner of being directly moved manually by a cooking person. In the present embodiment, the sliding rail assembly 130 is connected to both ends of one or both of the first baffle 110 and the second baffle 120, and the sliding rail assembly 130 is mounted on the smoke collecting hood 100.

It is understood that, when the first barrier 110 is movable and the second barrier 120 is fixed, the sliding rail assembly 130 is disposed at both the front end and the rear end of the first barrier 110. When the second barrier 120 is movable and the first barrier 110 is fixed, the sliding rail assemblies 130 are disposed at the front end and the rear end of the second barrier 120. When the first baffle 110 and the second baffle 120 are both movable, the front end and the rear end of the first baffle 110 and the second baffle 120 are both provided with a slide rail assembly 130.

Specifically, as shown in fig. 4 and 5, the slide rail assembly 130 includes a fixed rail 131 and a slide rail 132, the fixed rail 131 is fixed to the smoke collecting hood 100, the fixed rail 131 extends in the left-right direction of the smoke collecting hood 100, the slide rail 132 is slidably disposed on the fixed rail 131, and the slide rail 132 is connected to the corresponding first baffle 110 or the second baffle 120.

It will be appreciated that the engagement of the sliding rail 132 with the fixed rail 131 is equivalent to forming a telescopic rail, and when the sliding rail 132 moves into the fixed rail 131, the sliding rail assembly 130 contracts, and when the sliding rail 132 extends out of the fixed rail 131, the sliding rail assembly 130 expands. The slide rail assembly 130 with the structure occupies a small space, and the slide rail 132 can be accommodated through the fixed rail 131, so that the appearance is more attractive.

In a specific form, the fixed rail 131 is arranged in a strip-shaped groove, and a first limiting part 133 is arranged on the side wall of the fixed rail 131; two sides of the sliding rail 132 are respectively provided with a second limiting portion 134, the sliding rail 132 is sleeved in the groove of the fixed rail 131, and the second limiting portion 134 abuts against the inner side of the first limiting portion 133.

The second position-limiting portion 134 abuts against the inner side of the first position-limiting portion 133, so that the sliding rail 132 is prevented from sliding off the fixed rail 131 by the abutment of the second position-limiting portion 134 with the first position-limiting portion 133. Meanwhile, the first limiting portion 133 and the second limiting portion 134 are matched to play a role in guiding and limiting, so that the sliding rail 132 can move more smoothly.

Further, in the present embodiment, both ends of the fixed rail 131 are penetrated so that the sliding rail 132 can be bidirectionally moved leftward and rightward with respect to the fixed rail 131. For example, the sliding rail 132 connected to the second shutter 120 may move leftward with respect to its corresponding fixed rail 131, as shown in fig. 9; the sliding rail 132 to which the second shutter 120 is coupled may be moved rightward with respect to its corresponding fixed rail 131 as shown in fig. 10.

The fume collecting hood structure of the present embodiment further includes a driving assembly 140, and the driving assembly 140 is connected to one or both of the first baffle 110 and the second baffle 120 to be movable.

It is understood that the drive assembly 140 is only coupled to the movable barrier, i.e., the barrier to which the glide track assembly 130 is coupled. Specifically, the driving assembly 140 includes a first motor 141 and a rack 143, the first motor 141 is fixed on the fume collecting hood 100, a gear 142 is disposed on an output shaft of the first motor 141, the gear 142 is engaged with the rack 143, the rack 143 is disposed along the left and right direction of the fume collecting hood 100, and the rack 143 is connected with the corresponding first baffle 110 or the corresponding second baffle 120.

Two specific structural forms of the smoke collecting hood structure of the embodiment are described below.

The first implementation mode comprises the following steps:

the first shutter 110 is fixedly disposed, the second shutter 120 is movable, and the first shutter 110 is disposed at a middle position in the left-right direction of the smoke collecting hood 100.

The first baffle 110 is particularly fixed between the front and rear sidewalls of the collection hood 100, and the first baffle 110 is located at the middle of the collection hood 100. The front end and the rear end of the second baffle 120 are connected with the slide rail assembly 130, the second baffle 120 is connected with the driving assembly 140, and under the action of the driving assembly 140, the second baffle 120 slides along the left-right direction to realize the change of the first state, the middle state and the second state.

Similarly, the forward rotation and the reverse rotation of the first motor 141 of the driving assembly 140 may achieve the reciprocating motion of the second barrier 120 and the second barrier 120 in various states.

It can be understood that one of the sliding rail 132 of the first blocking plate 110 and the sliding rail 132 of the second blocking plate 120 can slide at least leftwards relative to the corresponding fixed rail 131, and the other can slide at least rightwards relative to the corresponding fixed rail 131, and it is to be noted that the first blocking plate 110 and the second blocking plate 120 can move away from each other at least to form the three-cavity smoke inlet state shown in fig. 7 and 8. In other cases, the first baffle 110 and the second baffle 120 can also move in the same direction to act as a means of regulating the flow of flue gas.

In the present embodiment, by the movement of the first baffle 110 and the second baffle 120, the smoke collecting hood 100 may form three uniform chambers, i.e., a left chamber 101, a middle chamber 102, and a right chamber 103. The scheme is suitable for three-hole cookers arranged at approximately equal intervals.
