Referring to fig. 1 and 2, a range hood 100 is provided according to an embodiment of the present disclosure. The range hood 100 includes a refrigeration module 10 and an air outlet module 20. The refrigeration module 10 is provided with an air outlet 101. The air outlet module 20 includes an air outlet duct 21, a flow dividing member 22 and a flow guiding member 23. The air inlet 201 of the air outlet module 20 is communicated with the air outlet 101, the diversion member 22 is connected with the diversion member 23, the diversion member 22 and the diversion member 23 are both located in the air outlet duct 21 and divide the air outlet duct 21 into a plurality of diversion channels 202, the diversion member 22 is used for diverting the air entering from the air outlet 101, and the diversion member 23 is used for guiding the diverted air to the plurality of diversion channels 202.

In range hood 100 of this application embodiment, because be provided with reposition of redundant personnel 22 and water conservancy diversion piece 23 in the air-out pipeline 21, and reposition of redundant personnel 22 and water conservancy diversion piece 23 have divided into a plurality of reposition of redundant personnel passageways 202 with air-out pipeline 21, after air that refrigeration module 10 made flows to air-out pipeline 21 in from air outlet 101, can be shunted by reposition of redundant personnel 22 earlier, in every reposition of redundant personnel passageway 202 is led to by water conservancy diversion piece 23 again, so, can guarantee that the wind that refrigeration module 10 made is when being discharged by range hood 100, the wind direction of wind can just be to the user, with promoting refrigeration effect, thereby guarantee user's use and experience.

The following is further described with reference to the accompanying drawings.

Referring to fig. 1, a range hood 100 includes a refrigeration module 10 and an air outlet module 20. The cooling module 10 and the air outlet module 20 may be disposed in a housing (not shown) of the range hood 100.

Specifically, the range hood 100 may be a wall-mounted range hood, an island range hood, or another type of range hood, which is not limited herein. In the embodiment shown in fig. 1, extractor hood 100 is a wall-mounted extractor hood.

The housing of the range hood 100 may be opened with a cold air outlet, and the air outlet module 20 may be disposed corresponding to the cold air outlet, so as to discharge the cold air produced by the refrigeration module 10 to the outside of the range hood 100 through the air outlet module 20 and the cold air outlet.

Referring to fig. 1 and 3, the refrigeration module 10 includes a first housing 11, an evaporator 12, and a first fan assembly 13. The evaporator 12 is located within the housing 10. The first fan assembly 13 is connected to the sidewall 110 of the first housing 11 and the air outlet module 20. The first housing 11 is a housing of the refrigeration module 10, and the housing is the first housing 11 for explanation.

Specifically, the top wall 111 of the first housing 11 is provided with an air inlet 1110. The low-temperature refrigerant flows through the duct 120 of the evaporator 12 to exchange heat with air. When the range hood 100 is used for cooling, external air may be sucked from the air inlet 1110 into the first housing 11, and the air entering the first housing 11 passes through the surface of the evaporator 12 and exchanges heat with the low-temperature refrigerant in the pipeline 120 of the evaporator 12. Because the cold air discharged to the kitchen space by the range hood 100 has a sinking tendency, the air is introduced from the air inlet 1110 of the top wall 111, so that the suction of the cold air can be reduced, and the refrigeration effect can be ensured.

In addition, please refer to fig. 1 to fig. 3, the first fan assembly 13 is connected to the air outlet 101 and the air inlet 201 of the air outlet module 20, so that when the refrigeration module 10 supplies air, the first fan assembly 13 can also increase the amount of cold air supplied to improve the refrigeration effect, thereby reducing the cooling time.

Specifically, when first fan subassembly 13 moves, can accelerate the air flow for the speed that air and evaporimeter 12 carry out the heat exchange accelerates, has more air conditioning to be blown to the kitchen space in a certain time moreover, reduces the cool-down time, promotes refrigeration effect. Wherein the first fan assembly 13 may comprise a centrifugal fan.

Referring to fig. 2, fig. 4 and fig. 5, the air outlet module 20 includes an air outlet duct 21, a flow divider 22, a flow guide 23 and an air inlet duct 24. The air inlet 201 is opened in the air inlet duct 24, and the air inlet duct 24 communicates with the air outlet 101 of the refrigeration module 10 and the air inlet 201 of the air outlet module 20, and is connected with the air outlet duct 20 in a bending manner.

Specifically, the flow dividing member 22 and the flow guiding member 23 are both located in the air outlet duct 21, and divide the air outlet duct 21 into a plurality of flow dividing channels 202. So, when refrigeration module 10 discharges air conditioning to air-out pipeline 21 from air inlet pipe 24 through first fan subassembly 13, air conditioning can be earlier in the kink department of air inlet pipe 24 and air-out pipeline 21 and change the air-out direction, and in air-out pipeline 21, through a plurality of reposition of redundant personnel passageways 202 alright with air conditioning reposition of redundant personnel, in order to change the air-out direction again, and discharge from air-out module 20, in order to guarantee that the wind direction of air conditioning can just be to the user, in order to promote refrigeration effect, thereby guarantee user's use and experience.

Referring to fig. 4 and 5, each of the flow dividing members 22 and the flow guiding members 23 may include a plurality of flow guiding members, and each flow guiding member 23 is correspondingly connected to one flow dividing member 22, so as to form a flow guiding structure 203.

In one embodiment, the plurality of flow guiding structures 203 are arranged in the air outlet duct 21 at equal intervals, and the flow guiding structure 203 farther away from the air inlet duct 24 is closer to the top wall 211 of the air outlet duct 24, so that the cool air discharged from the refrigeration module 10 can be uniformly distributed to each distribution channel 202 after passing through each flow guiding structure 203, and thus, the cool air discharged from the range hood 100 can be ensured to be uniform, so as to improve the user experience.

Referring to fig. 5, in each flow guiding structure 203, each flow dividing member 22 includes a horizontal section 221 and a vertical section 222 connected to each other, and each flow guiding member 23 includes a first section 231 and a second section 232 connected to each other. Wherein the second section 232 and the vertical section 222 extend in the same direction.

Specifically, the first section 231 of the diversion member 23 is obliquely connected to the vertical section 222, so that the cold air produced by the refrigeration module 10 entering the air outlet duct 21 through the air inlet duct 24 is blocked by the vertical section 222 of the diversion member 22 and is redirected by the first section 231 and the second end 232 of the diversion member 23 to be discharged to the user, thereby improving the user experience.

In some embodiments, referring to fig. 4 and 5, in the plurality of flow directing structures 203, the farther away from the air inlet duct 24, the longer the length of the vertical section 222, the greater the angle of inclination of the first section 231 relative to the vertical section 222. In other words, the shorter the length of the riser 222, the closer to the air inlet duct 24.

As can be seen from the above, the farther away from the air inlet duct 24, the closer the diversion structure 203 is to the top wall 211 of the air outlet duct 21, specifically, the closer the transverse section 221 of the flow divider 22 is to the top wall 211 of the air outlet duct 21. After the refrigeration module 10 discharges the cool air from the air outlet 101 of the refrigeration module 10 to the air inlet 201 of the air inlet duct 24 through the first fan assembly 13, the cool air is discharged to the air outlet duct 21 through the air inlet duct 24. At this time, the horizontal sections 221 and the vertical sections 222 of the plurality of flow dividing members 22 divide the cool air entering the air outlet duct 21 into different flow dividing channels 202.

It can be understood that the cold air passes through the plurality of the flow dividing members 22 in sequence and is divided continuously, and the air volume is reduced continuously. Therefore, the farther away from the air inlet duct 24, the closer the transverse section 221 of the flow divider 22 is to the top wall 211 of the air outlet duct 21, the longer the length of the vertical section 222 of the flow divider 22 needs to be, so as to ensure that the air volume in each flow divider 202 is close to each other when the cold air is discharged from the plurality of flow divider channels 202 of the air outlet duct 21, thereby ensuring that the cold air passing through the air outlet module 20 is cooled, and when the cold air outlet of the range hood 100 discharges, the air volume is uniform, so as to improve the user experience.

Referring to fig. 4 and 5, the farther away from the air inlet duct 24, the flow-guiding structures 203 are disposed, the greater the inclination angle of the first section 231 of each flow-guiding member 23 relative to the vertical section 222 of the flow-dividing member 22. As can be seen from the above, the diversion structures 203 are arranged at equal intervals in the air outlet duct 21, and the distances between the diversion structures 203 and the air inlet duct 24 are different.

When the cool air enters the air outlet duct 21, the wind direction angle passing through each flow guide structure 203 is also different, and then the angle of each flow guide element 23 required to correct the cool air passing through itself is also different. Therefore, the farther away from the air inlet duct 24, the larger the inclination angle of the first section 231 of each flow guide element 23 compared with the vertical section 222 of the flow guide element 22 is, so as to ensure that the direction of the cold air discharged from each flow guide channel 202 is substantially the same when the cold air passes through each flow guide structure 203 and is discharged from the corresponding flow guide channel 202, thereby ensuring that the direction of the cold air discharged from the range hood 100 is the same, improving the refrigeration performance, and ensuring the use experience of users.

In addition, in the plurality of flow guide structures 203, the lowest point of each flow guide member 23 is on the same plane. So, can guarantee that air conditioning is at every water conservancy diversion structure 203 to when discharging from the reposition of redundant personnel passageway 202 that corresponds, every reposition of redundant personnel passageway 202 exhaust air conditioning is the same with user's distance, and it is comparatively even to guarantee user perception air conditioning, thereby improves user's use and experiences.

In some embodiments, please refer to fig. 6 and 7, the air outlet module 20 may be further disposed as shown in fig. 6 and 7, and the air outlet duct 21 may include a first duct 211 and a second duct 212.

Specifically, first conduit 211 includes opposing first and second ends 2111 and 2112. Wherein the first end 2111 of the first duct 211 is connected to the intake duct 24. The second tube 212 is connected to the first tube 211 in a bent manner and is disposed at a second end 2112 of the first tube 211.

When the range hood 100 is in operation, the position of the first duct 211 is higher than the position of the second duct 212, so that after the air is blown to the air inlet duct 24 by the first fan assembly 13, when the cold air is discharged to the outside of the range hood 100 through the air inlet duct 24, the first duct 211, the second duct 212 and the cold air outlet, the discharge position of the cold air is higher. Because the cold air has the sinking trend, the cold air discharged from a higher position can be spread as much as possible in the sinking process so as to cover a wider kitchen space and ensure that the temperature of the kitchen space is more balanced. Moreover, the air outlet area of the second pipeline 212 is large, and the uniformity of the temperature of the kitchen space can be improved.

Further, both the flow guide 23 and the flow dividing member 22 are disposed within the second conduit 212, i.e., the flow guide 23 and the flow dividing member 22 divide the second conduit 212 into the plurality of flow dividing channels 202.

With continued reference to fig. 6 and 7, in some embodiments, each of the diversion channels 202 includes an air inlet 2021, and the inlets of the air inlets 2021 have the same width. When the cold air passes through the air inlet 2021, because the wind speed is the same and the air output of each shunting channel 202 is the product of the wind speed and the inlet width, the air output of the cold air discharged through each shunting channel 202 is the same, so that the cold air discharged from the range hood 100 can be ensured to be very uniform, and the use experience of users can be improved.

It should be noted that, compared to the air outlet module 20 shown in fig. 4, the air outlet module 20 shown in fig. 6 is closer to the bottom of the range hood 100. Therefore, the air outlet module 20 shown in fig. 6 can be ensured to be applied, and compared with the air outlet module 20 shown in fig. 4, the cold air outlet of the range hood 100 discharging cold air is closer to the user, so that the user can feel the cold air more quickly, thereby ensuring the user experience.

In some embodiments, referring to fig. 8 and 9, the air outlet module 20 may be further disposed as shown in fig. 8 and 9.

Specifically, referring to fig. 10, in each flow guiding structure 203, each flow dividing member 22 includes a horizontal section 221 and a vertical section 222 connected to each other.

Wherein the flow guide 23 and the vertical section 222 are connected obliquely. Moreover, in the plurality of flow guiding structures 203, the farther away from the air inlet duct 24, the greater the inclination angle of the flow guiding element 23 compared with the vertical section 222. So, can guarantee that air conditioning is at every water conservancy diversion structure 203 to when discharging from the reposition of redundant personnel passageway 202 that corresponds, every reposition of redundant personnel passageway 202 exhaust air conditioning direction is unanimous basically, thereby guarantees range hood 100 exhaust air conditioning's direction unanimity, thereby improves refrigeration performance, experiences in order to guarantee user's use.

As can be seen from the above, among the plurality of flow guiding structures 203, the flow guiding structure 203 farther from the air inlet duct 24 is closer to the top wall 211 of the air outlet duct 21, and the length of the corresponding vertical section 222 is longer. So, when can guaranteeing that air conditioning is discharged from a plurality of reposition of redundant personnel passageways 202 of air-out pipeline 21, the amount of wind in every reposition of redundant personnel passageway 202 is close mutually, so, can guarantee through the air conditioning of air-out module 20, when the air conditioning export of range hood 100 is discharged, the amount of wind is comparatively even to improve user's use and experience.

In addition, in the plurality of flow guide structures 203, the lowest point of each flow guide member 23 is on the same plane. So, can guarantee that air conditioning is at every water conservancy diversion structure 203 to when discharging from the reposition of redundant personnel passageway 202 that corresponds, every reposition of redundant personnel passageway 202 exhaust air conditioning is the same with user's distance, and it is comparatively even to guarantee user perception air conditioning, thereby improves user's use and experiences.

It should be noted that the air outlet module 20 shown in fig. 8 is closer to the bottom of the range hood 100 than the air outlet module 20 shown in fig. 4 and the air outlet module 20 shown in fig. 6. Therefore, the air outlet module 20 shown in fig. 8 can be ensured to be applied, and compared with the air outlet module 20 shown in fig. 4 and the air outlet module 20 shown in fig. 6, the cold air outlet of the range hood 100 discharging cold air is closer to the user, so that the user can feel the cold air more quickly, and the user experience is ensured.

Referring to fig. 1 and 11, the range hood 100 according to the embodiment of the present disclosure may further include a main body 30 and a heating module 40.

The main body 30 includes a first side 301 and a second side 302 opposite to each other, and a flue 31 is provided in the main body 30. The cooling module 10 is disposed on the first side 301, the heating module 40 is disposed on the second side 302, the heating module 40 is connected to the cooling module 10 through a cooling medium pipe (not shown), and an air outlet 401 of the heating module 40 is communicated with the flue 31 through a hot air channel 41.

Specifically, the range hood 100 is installed on a wall, and the refrigeration module 10 and the heating module 30 are respectively arranged on two outer sides of the main body 30 of the range hood 100, so that the space on the range hood 100 can be fully utilized, the occupation of a kitchen cabinet or the space on the ground is avoided, the occupation of the kitchen space is reduced, and the user activity is more extended.

The range hood 100 of the embodiment of the application does not need to be provided with an external unit. The first side 301 is the left side of the body 30 and the second side 302 is the right side of the body 30. It is understood that in other embodiments, the first side 301 may be a right side of the body 30 and the second side 302 may be a left side of the body 30.

In some embodiments, the main body 30 can be used as a frame of the range hood 100, the flow guide structure 50 is further disposed below the main body 30, a smoke suction port (not shown) can be disposed at a bottom of the flow guide structure 50, a fan assembly (not shown) can be disposed in the flue 31 of the main body 30, and when the fan assembly works, the fan assembly can suck oil smoke from the smoke suction port and discharge the oil smoke to a common flue or an outdoor environment through the flue 31 and the smoke pipe. Wherein the fan assembly may comprise a centrifugal fan.

More specifically, the refrigeration module 40 is connected to the heating module 10 through a refrigerant pipeline, when the range hood 100 performs refrigeration, the heating module 40 conveys a low-temperature refrigerant to the refrigeration module 10 through the refrigerant pipeline, the low-temperature refrigerant performs heat exchange with air in the refrigeration module 10 to form a high-temperature refrigerant, the high-temperature refrigerant flows back to the heating module 40 through the refrigerant pipeline, the high-temperature refrigerant performs heat exchange with air in the heating module 40 to form a low-temperature refrigerant again, and the cycle refrigeration is performed. The temperature of the air after heat exchange in the refrigeration module 10 is reduced to form cold air, and the cold air is discharged to the kitchen space through the air outlet 101 of the refrigeration module 10, the air outlet module 20 and the cold air outlet of the range hood 100, so that the kitchen space is cooled.

The air temperature of the heating module 40 after heat exchange rises to form high-temperature air, and the high-temperature air is discharged to the flue 31 through the air outlet 401 of the heating module 40 and the hot air channel 41, and is discharged to a public flue or outdoors through the flue 31. The high temperature air generated in the refrigerating process does not substantially affect the refrigerating effect of the kitchen environment since it is discharged to the public flue or the outside through the flue 31.

In some embodiments, the range hood 100 includes the airflow guide structure 50, and the cooling module 10, the main body 30, and the heating module 40 are disposed above the airflow guide structure 50. Thus, the installation space utilization rate of the range hood 100 is improved.

Specifically, the installation space of the range hood 100 may be a kitchen space, the diversion structure 50 is close to the user side, and the ground side, and the refrigeration module 10, the main body 30, and the heating module 40 are disposed above the diversion structure 50, so that the main structural components of the range hood 100 are located at a position above the kitchen space, more positions below the kitchen space may be used for installing storage compartments such as a wall cabinet, and the opening degree of the top of the head of the user may also be improved.

Referring to fig. 1, 3 and 11, in some embodiments, the heating module 40 may include a second casing 42, a condenser 43 and a compressor 44, the condenser 43 is located in the second casing 42, the compressor 44 is located outside the second casing 42, the air outlet 401 of the heating module 40 is opened on a side wall 421 of the second casing 42, and a top wall 422 of the second casing 42 is provided with a second air inlet 4220. Thus, the refrigeration effect can be ensured.

Specifically, the high-temperature refrigerant flows through the tubes of the condenser 43 to exchange heat with air. The top wall 422 of the second casing 42 is provided with a second air inlet 4220, so that when the range hood 100 is used for cooling, external air can be sucked from the second air inlet 4220 and enters the second casing 42, and the air entering the second casing 42 exchanges heat with a high-temperature refrigerant in a pipeline of the condenser 43 on the surface of the condenser 43. Because the cold air discharged to the kitchen space by the range hood 100 has a sinking tendency, the air is introduced from the second air inlet 4220 of the top wall 422 of the second housing 42, so that the suction of the cold air can be reduced, and the refrigeration effect can be ensured.

The compressor 44 is connected to the condenser 43 and the evaporator 12 via refrigerant pipes. The compressor 44 can compress a low-temperature and low-pressure refrigerant (gas) returned from the evaporator 12 into a high-temperature and high-pressure refrigerant (gas), and condense the refrigerant (gas) into a medium-temperature and high-pressure refrigerant (liquid) through the condenser 43, and the refrigerant (liquid) becomes a low-temperature and low-pressure refrigerant (liquid) after being throttled by the throttle valve. The low-temperature and low-pressure refrigerant (liquid) is sent to the evaporator 12, absorbs heat in the evaporator 12, evaporates to become a low-temperature and low-pressure refrigerant (gas), and is sent to the compressor 44 again, thereby completing the refrigeration cycle.

In some embodiments, the cooling module 40 further includes a second fan assembly 45, the second fan assembly 45 is connected to the sidewall 421 of the second housing 42 and the hot air channel 41, and the second fan assembly 45 communicates the air outlet 401 of the heating module 40 and the flue 18. Therefore, the heat dissipation efficiency can be improved.

Specifically, when the second fan assembly 45 operates, the air flow can be increased, so that the heat exchange speed between the air and the condenser 43 is increased, and more hot air is blown to the flue 31 in a certain time, thereby improving the heat dissipation efficiency of the condenser 43. The second fan assembly 45 may comprise a centrifugal fan.

In some embodiments, referring to fig. 1 and 11, a peripheral wall of the flue 31 is provided with a through hole 310, the hot air channel 41 is communicated with the through hole, an inner surface of the peripheral wall of the flue 31 is provided with a stopper 311, the stopper 311 covers the through hole 310, and a top of the stopper 311 is provided with a vent hole 312. Therefore, the negative influence of the direct blowing of hot air on the smoking effect can be improved.

Specifically, when the range hood 100 is used for cooling, the heating module 40 generates hot air, and the hot air is discharged into the flue 31 through the air outlet 401 of the heating module 40, the hot air channel 41 and the through hole 310. If the hot air blows directly, the smoke suction airflow formed when the fan assembly in the main body 30 works can be influenced, extra disturbance is generated on the smoke suction airflow, and the smoke suction effect is negatively influenced.

By arranging the stopper 311, the stopper 311 covers the through hole 310, so that the hot air discharged from the through hole 310 is prevented from blowing directly, the hot air can be discharged into the flue 31 through the vent holes 312 at the top of the stopper 311, the hot air is turned into upward flow by being blocked by the stopper 311, the flow direction of the hot air is basically the same as that of the smoke flow generated during smoking, and the hot air discharged into the flue 31 does not have negative influence on the smoke effect. Meanwhile, the arrangement of the stopper 311 can also reduce the amount of oil smoke entering the heating module 40, thereby reducing oil smoke pollution to the heating module 40.

In some embodiments, referring to fig. 11, the stop 311 includes a windward surface 3111, and the windward surface 3111 is curved. Thus, noise can be reduced.

Specifically, the stopper 311 is disposed in the flue 31, when the range hood 100 smokes, a smoking airflow is formed in the flue 31, and the smoking airflow collides with the arc windward surface 3111, so that noise generated during collision can be reduced, and user experience can be improved.
