Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. 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 application.
Referring to fig. 1 to 3, in the first embodiment of the present application, a kitchen fresh air cooling device 1000 includes a fresh air duct 1100, a cooling assembly 1200, a fan assembly 1300, a hot air duct 1400, and a cold air duct 1500.
The fresh air duct 1100 is used for introducing outdoor fresh air, that is, the outdoor fresh air enters the kitchen fresh air refrigeration device 1000 through the fresh air duct 1100.
The refrigeration assembly 1200 includes a semiconductor refrigeration chip 1210 having a cold end 1211 and a hot end 1212, wherein the refrigeration assembly 1200 has formed therein a refrigeration passageway 1201 proximate the cold end 1211 and a heat dissipation passageway 1202 proximate the hot end 1212.
Specifically, the cold end 1211 and the hot end 1212 of the semiconductor refrigeration sheet 1210 are disposed opposite to each other, and when the semiconductor refrigeration sheet 1210 operates, heat is transferred between the cold end 1211 and the hot end 1212, specifically, the heat is transferred from the cold end 1211 to the hot end 1212, so that the temperature of the cold end 1211 decreases and the temperature of the hot end 1212 increases.
Meanwhile, the cold end 1211 of the semiconductor refrigeration chip 1210 is arranged in the refrigeration channel 1201, the hot end 1212 is arranged in the heat dissipation channel 1202, the temperature of the air flow entering the refrigeration channel 1201 is reduced after the air flow exchanges heat with the cold end 1211, and the heat on the hot end 1212 is taken away by the air flow entering the heat dissipation channel 1202 after the air flow exchanges heat with the hot end 1212, so that the purpose of dissipating heat of the semiconductor refrigeration chip 1210 is achieved.
The fan assembly 1300 is configured to introduce a part of outdoor fresh air in the fresh air duct 1100 into the refrigeration channel 1201, and convert the outdoor fresh air into a refrigeration airflow after exchanging heat with the cold end 1211; and the other part of the outdoor fresh air is guided into the heat dissipation channel 1202, and is converted into heat dissipation airflow after heat exchange with the hot end 1212.
Specifically, when the outdoor fresh air introduced by the fresh air duct 1100 is transported by the fan assembly 1300, a portion of the air enters the cooling channel 1201 to exchange heat with the cold end 1211 of the semiconductor cooling plate 1210 and then is converted into a cooling air flow, and another portion of the air enters the heat dissipation channel 1202 to exchange heat with the hot end 1212 of the semiconductor cooling plate 1210 and then is converted into a heat dissipation air flow.
In an application scenario, as shown in fig. 2, the fan assembly 1300 is disposed between the fresh air duct 1100 and the cooling assembly 1200, and in other application scenarios, the fan assembly 1300 may be disposed at other positions as long as the outdoor fresh air in the fresh air duct 1100 can enter the cooling channel 1201 and the heat dissipation channel 1202.
The hot air duct 1400 is communicated with the heat dissipation channel 1202 to discharge the heat dissipation airflow to the outside; the cool air duct 1500 communicates with the cooling passage 1201 to discharge the cooling air flow into the room.
Specifically, the working flow of the kitchen fresh air refrigerating device 1000 is as follows:
after outdoor fresh air enters the kitchen fresh air refrigeration device 1000 through the fresh air duct 1100, under the action of the fan assembly 1300, one part of the fresh air enters the refrigeration channel 1201, and the other part of the fresh air enters the heat dissipation channel 1202.
The outdoor fresh air entering the refrigerating channel 1201 is subjected to heat exchange with the cold end 1211 of the semiconductor refrigerating sheet 1210, the temperature of the outdoor fresh air is reduced, the outdoor fresh air is converted into refrigerating air flow, and the refrigerating air flow is discharged to the indoor through the cold air duct 1500 to reduce the indoor temperature. The refrigerating airflow entering the room is finally mixed with the indoor air with the oil smoke, and then is sucked away by the range hood and discharged to the outside.
The outdoor fresh air entering the heat dissipation channel 1202 absorbs heat of the hot end 1212 after exchanging heat with the hot end 1212 of the semiconductor chilling plate 1210, and is converted into heat dissipation air flow, and then the heat dissipation air flow is discharged to the outdoor through the heat dissipation channel 1202, so that the purpose of dissipating heat for the semiconductor chilling plate 1210 is achieved.

Meanwhile, as the layout of the centrifugal fan 3310 is changed and is matched with the centrifugal fan 3310, the third embodiment also changes the layout of the hot air duct 3400 and the cold air duct 3500 on the basis of the first embodiment and the second embodiment, specifically combining fig. 11 and 12, at this time, the hot air duct 3400 and the cold air duct 3500 are changed into vertical structures, specifically, the heights are obviously improved, and meanwhile, the cross-flow fans 3700 are arranged at the bent parts 3410 in the hot air duct 3400 and the cold air duct 3500, so that the flow rates of the air flows in the hot air duct 3400 and the cold air duct 3500 can be independently adjusted.
In addition, a guide vane 3800 is further arranged in the cold air duct 3500 to divide the refrigerating air flow into a plurality of sub-air flows and guide the sub-air flows to the cold air outlet 3501 respectively, and in an application scene, as shown in fig. 12, the guide vane 3800 extends from the interior of the cold air duct 3500 to the outlet air curtain 3600, so that the refrigerating air flow can enter the room from the outlet air curtain 3600 more stably and uniformly.
