A range hood 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 7.

As shown in fig. 1 and 2, a range hood 100 according to an embodiment of the present invention includes: a main body 1 and a refrigeration module 2. The main body 1 has a main air inlet 11 and a main air outlet 12, and a main blower 13 is arranged in the main body 1. The refrigeration module 2 is arranged on the main machine body 1, the refrigeration module 2 is provided with a refrigeration inlet 21 and a refrigeration outlet 22, and the refrigeration module 2 comprises: a refrigeration fan 23 and at least one refrigeration unit 24, the refrigeration unit 24 comprising: the refrigeration box 241 is a closed box, and the refrigeration fan 23 is used for driving airflow to flow through the outer heat dissipation sheet 242 after being sucked from the refrigeration inlet 21 and blow out from the refrigeration outlet 22.

It can be understood that, in the cooking process of the user, the main fan 13 is used for driving the oil smoke to be sucked from the main air inlet 11 and discharged from the main air outlet 12, so that the comfort level of the user during cooking can be improved, and the health of the human body can be protected. Meanwhile, the outer heat dissipation plate 242 is connected to the refrigeration box 241, the outer heat dissipation plate 242 has a lower temperature under the conduction of the refrigeration box 241, and when the airflow is sucked from the refrigeration inlet 21 and flows through the outer heat dissipation plate 242 by the refrigeration fan 23, the outer heat dissipation plate 242 cools the airflow, so that the refrigeration outlet 22 can blow out the cold airflow. Through the form of combining the air cooling and the liquid cooling, the area of the kitchen, which is just opposite to the refrigerating outlet 22, can be quickly cooled, the comfort level of a user during cooking can be further improved, and the phenomenon that the user sweats down the back due to high temperature in the cooking process is reduced.

The refrigeration box 241 is a sealed box which can protect the refrigerant from overflowing, and the use safety of the refrigeration module 2 can be improved. It can be understood that if open the both sides of refrigeration box, when the air current of refrigeration fan driven got into the refrigeration box through the ventilation duct water conservancy diversion, when the air current blew off from the opening of refrigeration box again in the refrigeration box, the air current carried out certain liquid easily, caused the phenomenon of blowing water, and the liquid that blows out can flow backward and cause certain potential safety hazard in getting into the host computer body. And the refrigeration box is communicated with the outside through the open hole, a human body can suck volatile refrigerant or the refrigerant carried by the water blowing phenomenon, the selectable range of liquid in the refrigeration box is limited for protecting the health of the human body, and ice blocks or ice water and the like can be usually placed in the refrigeration box. The refrigeration box 241 is a closed box, so that the selection range of the refrigeration box is not limited because the refrigeration agent is not blown out any more, for example, chemical solutions such as water, vegetable oil, liquid ammonia or liquid nitrogen can be selected, and the selectivity of a user is increased.

In addition, the main fan 13 and the refrigeration module 2 in the embodiment of the invention are mutually separated and do not interfere with each other, so that the influence of the refrigeration module 2 on the smoking effect of the main fan 13 can be reduced, and meanwhile, the smell of oil smoke in cool air blowing to a user can be reduced.

According to the range hood 100 of the embodiment of the invention, the refrigerating fan 23 is arranged for driving the airflow to flow through the outer heat dissipation sheet 242 after being sucked from the refrigerating inlet 21 and blow out from the refrigerating outlet 22, so that the air cooling and the liquid cooling can be combined to quickly cool the kitchen, and the cooking comfort of a user is improved. By setting the refrigeration box 241 as a closed box, the refrigerant can be protected from overflowing, thereby improving the safety of the refrigeration module 2 and reducing the water blowing phenomenon of the refrigeration module 2.

In some embodiments, as shown in fig. 3 and 4, the refrigeration unit 24 further comprises: the inner fins 243, the outer fins 242 and the inner fins 243 provided inside the refrigeration cassette 241 are attached to the same side wall of the refrigeration cassette 241. It will be appreciated that the provision of the inner fins 243 may increase the contact area of the refrigeration unit 24 with the refrigerant, and may increase the conduction effect between the refrigeration unit 24 and the refrigerant. The provision of the outer fins 242 may increase the contact area between the refrigeration unit 24 and the air flow, and may increase the conduction effect between the refrigeration unit 24 and the refrigerant. Therefore, the refrigerating fan 23 can accelerate the refrigeration of the air and blow the air to the refrigerating outlet 22 for discharge, the cooling rate and the cooling range of a kitchen are improved, the size of the refrigerating unit 24 can be reduced, and the occupied space of the refrigerating unit 24 is effectively reduced.

Specifically, as shown in fig. 3 and 4, the refrigeration cassette 241 includes a cassette body 2411 and a cassette cover 2412, one side of the cassette body 2411 is open, the cassette cover 2412 covers the cassette body 2411 to make the refrigeration cassette 241 a closed cassette, and the outer heat dissipation fins 242 and the inner heat dissipation fins 243 are both disposed on the cassette cover 2412. It can be understood that, when the refrigeration box 241 is installed, the inner cooling fin 243 is put into the refrigeration box 241 through the open side of the refrigeration box 241, at this time, the box cover 2412 covers the open side of the refrigeration box 241, the outer cooling fin 242 is located outside the refrigeration box 241, so that the inner cooling fin 243 is sealed in the refrigeration box 241, the refrigerant can be fully contacted, the energy dissipation is reduced, the outer cooling fin 242 is connected outside the refrigeration box 241, the air flow can be fully contacted, the conduction effect of the inner and outer cooling fins 242 can be further improved, and the refrigerant can still be kept in the refrigeration box 241 after being heated and melted. In addition, the inner and outer cooling fins are all arranged on the box cover 2412, on one hand, the box cover 2412 can play a role in sealing the refrigerant, on the other hand, the box cover 2412 can also fix and support the inner and outer cooling fins, and a fixing piece for supporting the inner and outer cooling fins is not needed to be additionally arranged, so that the material and the resource can be saved, and the size of the refrigeration unit 24 can be further reduced.

Of course, in other embodiments of the present invention, the cooling unit 22 may not have the inner cooling fins 243, or the cooling box 241 may have other components for increasing heat conduction, such as a stirring impeller.

In some embodiments, as shown in fig. 3 and 4, the refrigeration unit 24 has a plurality of outer fins 242 arranged in the same row, and adjacent two outer fins 242 in the same row define a heat dissipation passage 2421 therebetween in the same direction as the air flow. It will be appreciated that the plurality of outer fins 242 arranged in the same row may further increase the contact area of the outer fins 242 with the airflow, and may further increase the conduction effect between the refrigeration unit 24 and the airflow. Meanwhile, the arrangement of the plurality of radiating fins can also play a role in guiding air flow. Specifically, the airflow may be guided by the wall surfaces of the outer fins 242 and flow out of the heat dissipation passages 2421. Namely, on one hand, a heat dissipation channel 2421 which is consistent with the airflow direction is defined between two adjacent outer heat dissipation fins 242 in the same row, and the airflow can flow out from the heat dissipation channel 2421, and on the other hand, the wall surfaces of the outer heat dissipation fins 242 can play a role in guiding the airflow to form a strong flowing effect, so that the kitchen cooling time is shortened.

In some embodiments, as shown in fig. 1 and 2. The two refrigeration units 24 are provided, and the outer fins 242 are provided on the sides of the two refrigeration units 24 facing each other. Thus, the airflow can be sucked from the refrigeration inlet 21, then flow through the two outer heat dissipation fins 242, and be blown out from the refrigeration outlet 22, and the two refrigeration units 24 can further improve the refrigeration effect of the range hood 100. The outer heat dissipation plates 242 are disposed on one sides of the two refrigeration units 24 facing each other, so that the two refrigeration cases 241 are disposed on two sides of the two outer heat dissipation plates 242, and the airflow blown from the refrigeration outlet 22 is not blocked by the refrigeration cases 241, thereby improving the flow rate of the airflow and reducing the loss of the airflow.

In addition, the fan cover 231 can further limit and fix the refrigeration fan 23, and the working stability of the refrigeration fan 23 is improved.

Specifically, as shown in fig. 1 and 6, the bracket 25 is formed as a case, one side of which is open, and in which the refrigerating unit 24 is detachably received, and the other side of which is provided with an air passing opening 251 and to which the fan cover 231 is connected. It will be appreciated that the refrigeration unit 24 is removably received within the cabinet to facilitate installation and replacement of the refrigeration unit 24. In practical use, before cooking, a user can detach the refrigeration unit 24 and put the refrigeration unit into a refrigerator or other refrigeration equipment to freeze refrigerant, and the user can also be provided with a standby refrigeration unit 24 to replace the standby refrigeration unit 24 which is frozen in advance in the refrigerator or other refrigeration equipment when the refrigerant is melted, and put the detached refrigeration unit 24 into the refrigeration equipment to be frozen, so that the long-term cyclic utilization of the refrigeration unit 24 can be realized.

The other side of the box body is provided with an air outlet 251 and is connected with a fan cover 231. The fan guard 231 is thus arranged to direct the flow of cold air from the air inlet 251 of the refrigeration unit 24 out of the refrigeration outlet 22. Specifically, as shown in fig. 5, the fan guard 231 may include an arc-shaped deflector 2311, and the deflector 2311 may provide a good guiding effect for the flow of the cold airflow, so that the cold airflow smoothly transitions from the vertical direction along the arc-shaped surface of the deflector 2311, and the loss of the airflow is reduced.

It can be understood that the refrigeration unit 24 is arranged on the air inlet side of the refrigeration fan 23, so that the air flow of the refrigeration inlet 21 flows to the refrigeration fan 23 after being cooled by the refrigeration unit 24, the cold air flow can cool the refrigeration motor, and the service life of the refrigeration motor can be prolonged. The refrigeration unit 24 is disposed at the air inlet side of the refrigeration fan 23, so that the air outlet side of the refrigeration fan 23 is not obstructed by the outer heat dissipation sheet 242, and the cold air volume and the cold air flow rate of the air outlet can be effectively increased, so that the cold air can be blown farther. Meanwhile, the air inlet end can effectively reduce the flow velocity of the air inlet side by enlarging the area of the air inlet, increase the contact time between the air on the air inlet side and the outer radiating fins 242, and improve the refrigeration effect.

The air inlet wind scooper 26 can guide the flow direction of the airflow at the refrigeration inlet 21, and the air outlet wind scooper 27 can guide the flow direction of the airflow at the air outlet side, so that the airflow at the refrigeration outlet 22 forms a strong air outlet effect, and the refrigeration effect of the airflow kitchen is improved.

In some embodiments, as shown in fig. 1 and 6, the refrigeration module 2 is provided in the main body 1, and the refrigeration inlet 21 and the refrigeration outlet 22 are both located on the main body 1. Therefore, the refrigerating module 2, the refrigerating inlet 21 and the refrigerating outlet 22 are compact in layout, small in size and small in occupied space.

Wherein the refrigeration unit 24 is detachably provided from the refrigeration inlet 21 or the refrigeration outlet 22. It will be appreciated that the refrigeration unit 24 may be removable at the refrigeration inlet 21, or that the refrigeration unit 24 may be removable at the refrigeration outlet 22. The refrigeration unit 24 is arranged at the refrigeration inlet 21 or the refrigeration outlet 22, and an inlet for detaching the refrigeration unit 24 does not need to be additionally arranged, so that the convenience of replacement of a user can be improved, and the integrity and the attractiveness of the range hood 100 are improved. In other embodiments, the refrigeration cassette 241 may be provided with a handle 244 when the refrigeration unit 24 is detached from the refrigeration outlet 22, as shown in fig. 7, and the user may conveniently pull the refrigeration cassette 241 out of the main body 1 by means of the handle 244. Of course, the surface of the handle 244 may be provided with bumps or ribs to increase friction, so that the user can pull out the refrigeration cassette 241 quickly, thereby reducing finger slippage.

In some alternative embodiments, as shown in fig. 7, the bracket 25 is formed as a box and detachably connected to the fan housing 231, and one side of the bracket 25 facing the fan housing 231 is provided with an air inlet 251 and the other side is formed with a grill 252. In this way, the bracket 25 can be easily removed from the main frame while the fan guard 231 remains stationary. In actual use, the refrigeration unit 24 on the bracket 25 needs to be detached for refrigeration treatment, and the fan cover 231 is used for fixing and limiting the refrigeration fan 23, so that when the refrigeration unit 24 needs to be refrigerated, the bracket 25 needs to be detached to separate the bracket 25 from the fan cover 231. The arrangement of grid 252 does benefit to the middle of the air current direction and assembles, plays better cold blast effect, and the support 25 is pulled down together with the grid 252 of air inlet side when pulling down, simplifies the dismouting degree of difficulty.

In the example of fig. 7, the side of the refrigeration cassette 241 facing the customer is provided with a handle 244 to facilitate access to the refrigeration cassette 241 from the side facing the customer. The air inlet side grill 252 serves as an upper cover of the refrigeration cassette 241, and the grill 252 and the refrigeration cassette 241 are formed as a single body.

Optionally, the refrigeration fan 23 is a cross-flow fan, and certainly, the refrigeration fan 23 may also be a centrifugal fan or other types of machines, which can achieve a good air outlet effect, and the specific form of the refrigeration fan 23 is not limited herein.
