Referring to fig. 1-3, a range hood structure 100 according to an embodiment of the present application includes a condenser assembly 10, a range hood fan 20, and a flow guide 30. The cigarette machine structure 100 of the present application is applied to an air-conditioning cigarette machine, and may also be applied to other devices suitable for the cigarette machine structure 100, etc., and is not limited herein.

The condenser assembly 10 has an air outlet 11. Specifically, during cooling, the temperature at the condenser assembly 10 is relatively high, so that during use, the condenser assembly 10 needs to be cooled by heat dissipation, and the heat after cooling needs to be exhausted to the outside from the air outlet 11.

The oil smoke blower 20 comprises an oil smoke blower shell 21, an air inlet 211 is formed in the oil smoke blower shell 21, and the oil smoke blower 20 can drive outside air to enter the air inlet 211. More specifically, the lampblack fan 20 further comprises a fan blade 22 arranged in the lampblack fan shell 21, and negative pressure can be generated under the rotation action of the fan blade 22, so that outside air can be introduced into the lampblack fan shell 21 from the air inlet 211. Specifically, the oil smoke fan casing 21 is further provided with an air outlet 212 communicated with the inside of the oil smoke fan casing 21, and air introduced into the oil smoke fan casing 21 can be discharged from the air outlet 212.

The guiding member 30 is located outside the oil smoke blower housing 21 and has a guiding cavity 31 communicating the air outlet 11 and the air inlet 211. The flow guiding cavity 31 has a flow guiding arc 311 defining the flow guiding cavity, and the flow guiding arc 311 is disposed around at least a portion of the air inlet 211 to guide the air discharged from the air outlet 11 to the air inlet 211.

It should be noted that the air guiding arc surface 311 is disposed around at least a portion of the air inlet 211, and the air guiding arc surface is not necessarily surrounded by 360 degrees, and may be surrounded by 180 degrees or 90 degrees, and the like, which is not limited specifically, and the first radial distance between the air guiding arc surface 311 and the edge of the air inlet 211 may be equal or may be unequal, and is not limited specifically.

By arranging the diversion member 30 to connect the air outlet 11 of the condenser assembly 10 and the air inlet 211 of the lampblack fan 20 and smoothly guiding the air discharged from the air outlet 11 to the air inlet 211 through the diversion arc 311, the heat dissipation air discharged from the condenser assembly 10 can be discharged together with the lampblack in the lampblack fan 20, so that the lampblack cannot flow back to the air inlet 211 and enter the air outlet 11, and the evaporator and the condenser assembly 10 of the air-conditioning range hood cannot be polluted.

In an embodiment of the present application, referring to fig. 1 and 2, the condenser assembly 10 is located on one side of the fume fan 20 in a first direction. Specifically, the first direction is the vertical direction shown in fig. 2.

Further, the air discharge opening 11 of the condenser assembly 10 is disposed toward the soot blower 20 in the first direction. Therefore, the air outlet 11 of the condenser assembly 10 can directly blow out the heat-dissipating air from the bottom to the lampblack blower 20, and the discharge path is shortened.

Further, a guide inlet 32 communicating with the guide chamber 31 is formed at a side of the guide member 30 facing the condenser assembly 10, and the guide inlet 32 is disposed opposite to the air outlet 11 in the first direction.

In this way, the heat dissipation air blown out from the air outlet 11 can directly enter the diversion inlet 32 without changing the flow direction, so that the kinetic energy loss is reduced, and the discharge path is shortened.

Referring to fig. 3 and 4, in particular, in the embodiment of the present application, the flow guide member 30 includes a flow guide cover 33 and a cover plate, a first side of the flow guide cover 33 has a first opening 331, and the cover plate is covered at the first opening 331. And the cover plate and the pod 33 define a pod inlet 32 on a second side adjacent the first side. Specifically, the cigarette machine structure 100 includes a cigarette machine soot housing 40, the cigarette machine soot housing 40 having a soot space 41, the soot housing 40 also having a back plate 42 defining the soot space 41, the cover plate may be part of the back plate 42 of the air conditioning cigarette machine 200. The pod 33 is mounted to the back plate 42 through a first side and defines a pod cavity 31 with the back plate 42.

Further, a second opening 332 is formed on a side of the baffle 30 opposite to the cover plate, and the air inlet 211 is covered by the second opening 332. Specifically, the inner shape of the second opening 332 is the same as the inner shape of the intake vent 211.

In the embodiment of the present application, the axis of the air outlet 11 intersects with the axis of the air inlet 211. Thus, the arrangement of the condenser assembly 10 and the fume fan 20 of the range hood structure 100 can be more reasonable and compact.

Specifically, the lampblack fan shell 21 is provided with a first side wall 213 provided with the air inlet 211, and the first side wall 213 is arranged obliquely relative to the axis of the air outlet 11.

Referring to fig. 1 and 2, in the embodiment of the present application, the condenser assembly 10 further includes a condenser and a first fan, wherein the first fan is capable of driving the outside air to blow toward the condenser and discharge the outside air from the air outlet 11. Under the action of the first fan, air is blown to the condenser to dissipate heat and cool the condenser, and the dissipated air is discharged through the air outlet 11.

In other embodiments, the first fan may be omitted, and instead, the negative pressure of the soot fan 20 drives the outside air to blow toward the condenser, and the air after heat dissipation is exhausted through the air outlet 11 and enters the air inlet 211.

In the embodiment of the present application, the oil smoke fan casing 21 further has an oil smoke inlet 214, the external oil smoke can enter the inside of the oil smoke fan casing 21 through the oil smoke inlet 214, and the oil smoke inlet 214 and the air inlet 211 are independently disposed. Specifically, the smoke inlet 214 and the air inlet 211 are respectively disposed on two opposite sides of the oil smoke fan casing 21, so that interference of air flow entering between the two can be reduced, and efficiency of air flow entering is improved. In other embodiments, the lampblack fan casing 21 may have no smoke inlet 214, and the air inlet 211 can function as the smoke inlet 214.

Referring to fig. 2 and 4, in some embodiments, the flow guiding arc 311 includes a first arc 3111, and a first radial distance L1 between the first arc 3111 and the inlet 211 decreases along the airflow direction in the flow guiding cavity 31 on a first cross section AA of the flow guiding member 30 along the radial direction of the inlet 211.

It should be noted that the first radial distance L1 between the first arc face 3111 and the edge of the air inlet 211 refers to a distance between the first arc face 3111 and an intersection point of a connecting line and the edge of the air inlet 211 in a connecting line between the first arc face 3111 and the center of the air inlet 211.

So, through setting up first cambered surface 3111, can be with the air that introduces in the water conservancy diversion chamber 31, successfully lead to air intake 211 to because the first radial distance that has set up between first cambered surface 3111 and the air intake 211 reduces along the air current direction in the water conservancy diversion chamber 31 gradually, can cushion the air in the earlier stage of air admission, in order to avoid air velocity too fast, and the influence is to the effect of air intake 211 air.

In addition, the air can also be made to generate vortex after passing through the first cambered surface 3111, and the generation of the vortex can accelerate the air inlet speed, so that the air inlet efficiency is improved.

Preferably, the downstream end of the first cambered surface 3111 in the airflow direction is tangent to the intake vent 211 or a concentric circle of the intake vent 211.

Specifically, the intake vent 211 is circular, and in other embodiments, may also be oval, or may be a special shape that is only curved near a portion of the downstream end of the first cambered surface 3111 in the airflow direction, and is not limited in particular.

Thus, air can tangentially enter the air inlet 211, and the air flows more smoothly.

Referring to fig. 1 to 4, in the embodiment of the present application, the range hood fan 20 is a centrifugal fan, the centrifugal fan includes a fan blade, the range hood fan housing 21 includes a centrifugal volute, and the fan blade 22 is disposed in the centrifugal volute. Therefore, the centrifugal fan and the centrifugal volute can be designed to be matched with air introduced through the flow guide arc surface 311, and the working efficiency of the centrifugal fan is improved.

In the embodiment of the present application, the downstream end of the first cambered surface 3111 in the airflow direction is tangent to a concentric circle of the intake vent 211. That is, a certain first radial distance is left between the downstream end of the first cambered surface 3111 in the airflow direction and the air inlet 211.

In an embodiment of the present application, a projection of the first cambered surface 3111 in the first direction towards the condenser assembly 10 covers at least part of the guide flow inlet 32.

In this way, the heat dissipation air blown out from the air outlet 11 directly impacts on the first cambered surface 3111 through the flow guiding inlet 32, and then rapidly enters the air inlet 211 under the guidance of the first cambered surface 3111. Therefore, the kinetic energy loss is further reduced, and the air inlet speed is accelerated.

In some embodiments, the center of the air outlet 11 and the center of the air inlet 211 have a distance therebetween in a second direction perpendicular to the first direction.

Specifically, the second direction is a horizontal direction as shown in fig. 2.

Because the distance is arranged between the center of the air outlet 11 and the center of the air inlet 211, the air entering from the flow guide inlet 32 can be discharged from the air inlet 211 without being directly discharged from the air inlet 211 but only under the flow guide effect of the flow guide arc surface 311, and the flow guide effect is improved.

Referring to fig. 1 to 4, in the embodiment of the present disclosure, the flow guiding cavity 31 further has a first flow guiding plane 312 defining the flow guiding cavity, the first flow guiding plane 312 and the flow guiding arc surface 311 are sequentially connected along the airflow direction in the flow guiding cavity 31, the first flow guiding plane 312 is tangent to the flow guiding arc surface 311 at the connection position, and the first flow guiding plane 312 is disposed in an inclined manner toward the air outlet 11 relative to the axis of the air outlet 11.

By arranging the first air guiding plane 312 at the upstream end of the air guiding arc surface 311 along the airflow direction in the air guiding cavity 31, the air can be guided to smoothly enter the air guiding arc surface 311. Furthermore, the opening of the upstream end of the first flow guiding plane 312 along the airflow direction is larger, so that more heat dissipation air exhausted from the air outlet 11 can be introduced, and the heat dissipation effect is improved.

Further, an upstream end of the first flow guiding plane 312 in the airflow direction is used to define the flow guiding inlet 32.

Therefore, the air entering the guide inlet 32 can be directly guided to the guide arc surface 311 by the first guide plane 312, and the guiding effect is improved.

Specifically, the first flow guiding plane 312 and the first arc surface 3111 are sequentially connected along the airflow direction.

Referring to fig. 4, in some embodiments, the flow guiding arc surface 311 further includes a second arc surface 3112, the first arc surface 3111 and the second arc surface 3112 are sequentially connected along the airflow direction, and a second radial distance L2 between the second arc surface 3112 and the air inlet 211 is gradually increased along the airflow direction on the first cross section AA.

Because the second radial distance L2 between the second cambered surface 3112 and the air inlet 211 gradually increases along the airflow direction, when the air is guided to the downstream end of the first cambered surface 3111 along the airflow direction, the flowing speed of the air can be slowed down, and the air can further flow into the air inlet 211 more.

Further, the first cambered surface 3111 and the second cambered surface 3112 are in a common circle.

The first arc surface 3111 and the second arc surface 3112 are in a same circle, that is, the first arc surface 3111 and the second arc surface 3112 are arc segments on the same circle.

Through setting up first cambered surface 3111 and second cambered surface 3112 is the same circle, can simplify the structure of water conservancy diversion cambered surface 311, and avoid first cambered surface 3111 and second cambered surface 3112 at the junction sudden change, and influence the speed that the air flows, and then influence the air inlet effect.

Further, a central angle of the first cambered surface 3111 is larger than that of the second cambered surface 3112. So, can form a wind tangent plane after first cambered surface 3111 is flowed through to the air, and continue to lead to second cambered surface 3112 with wind, and then form the vortex in second cambered surface 3112 department, improved the water conservancy diversion effect.

In some embodiments, flow directing arc 311 further includes a third arc 3113, where second arc 3112 and third arc 3113 are sequentially connected along the airflow direction, where second arc 3112 and third arc 3113 are tangent, and where the radius of third arc 3113 is smaller than the radius of second arc 3112.

Through set up third cambered surface 3113 at second cambered surface 3112 along the low reaches end of air current direction, and make second cambered surface 3112 tangent at the junction with third cambered surface 3113, the radius of third cambered surface 3113 is less than the radius of second cambered surface 3112, can make third cambered surface 3113 be close to towards air intake 211 along the low reaches end of air current direction, and then make the air after third cambered surface 3113 cushions, can return to air intake 211 department once more, and then improve the air inlet effect.

In some embodiments, the diversion cavity 31 further has a second diversion plane 313 defined therein, the second diversion plane 313 is connected to a downstream end of the diversion arc 311 along the airflow direction in the diversion cavity 31, and the diversion arc 311 is tangent to the second diversion plane 313 at the connection.

The second flow guiding plane 313 is connected to the downstream end of the flow guiding arc surface 311 along the airflow direction in the flow guiding cavity 31, and air which is not guided to the air inlet 211 by the flow guiding arc surface 311 is difficult to flow in a direction far away from the air inlet 211, so that the air is easier to be sucked into the air inlet 211 under the negative pressure action of the lampblack fan 20.

In particular, the second flow guiding plane 313 is parallel to the first direction.

Referring to fig. 1 and 2, in some embodiments, the range hood structure 100 further includes a smoke housing 40, the smoke housing 40 has a smoke space 41, and the smoke blower 20 is disposed in the smoke space 41.

Further, a distance is provided between the flow guide member 30 and the oil smoke fan housing 21 along the axial direction of the air inlet 211 to form a second communication space, and the second communication space is communicated with the oil smoke space 41.

Through setting up second intercommunication space, can make the oil smoke also get into air intake 211 department through this second intercommunication space for the air intake not only can be used for introducing the heat dissipation air, can also be used for introducing the oil smoke.

In some embodiments, the cigarette maker arrangement 100 further comprises an air conditioning housing 50, the air conditioning housing 50 having an air conditioned space 51, the condenser assembly 10 being disposed within the air conditioned space 51.

In order to prevent the oil smoke from entering the air conditioning space 51 through the oil smoke space 41, the range hood structure 100 further includes a partition for partitioning the oil smoke space 41 and the air conditioning space 51, the partition is opened with a communication port, one end of the condensing assembly 10 having the air outlet 11 is hermetically fixed on the partition, and the air outlet 11 is communicated with the communication piece 61.

In some preferred embodiments, the range hood construction 100 further comprises an opening and closing member provided at the air discharge opening 11 for opening or closing the air discharge opening 11. Specifically, the switch piece is arranged at the communication port.
