Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a cooling device and cooking equipment. Background Technology

[0002] When a traditional steam oven is opened after cooking, a large amount of steam rushes out of the cavity and directly onto the user's face. This can cause minor issues like blurred vision or, in severe cases, burns. Furthermore, the large amount of steam increases humidity in the kitchen, and over time, this dampness can corrode furniture and appliances. The continuous release of high-temperature steam during use also poses a risk of burns.

[0003] In addition, in the summer when the temperature is high, if you put food in a steam oven and start the timer function, the food is prone to spoilage while waiting for it to cook, resulting in a poor user experience.

[0004] Therefore, there is an urgent need for a cooling device to solve the above problems. Utility Model Content

[0053] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0054] Please refer to Figures 1-9 This utility model provides a cooling device, including an air duct 1, a refrigeration component 2, a cooler 5, an exhaust valve 42, and an intake valve 41. The air duct 1 includes an air inlet channel 11 and an air outlet channel 12. The refrigeration component 2 is installed on the air duct 1 and located within the air inlet channel 11 and the air outlet channel 12. The cooler 5 is connected to the air inlet channel 11. The intake valve 41 is connected to the air inlet channel 11 and is used to control the opening and closing of the air inlet channel 11. The exhaust valve 42 is connected to the air outlet channel 12 and is used to control the opening and closing of the air outlet channel 12. Specifically, the cooling device is installed on the cooking equipment. After cooking, the high-temperature steam can be discharged through the air outlet 12 by opening the exhaust valve 42. The high-temperature steam discharged through the air outlet 12 is condensed and cooled by the cooling component 2, thus preventing the high-temperature steam from being directly discharged from the cooking equipment and causing burns to the user. When the cooking equipment needs to preserve food, the air inlet valve 41 and exhaust valve 42 can be opened, and the air cooler 5 can draw air from outside the cooking equipment into the air inlet 11. The cooling component 2 then cools the room-temperature air in the air inlet 11 and delivers it into the cooking equipment, thereby reducing the temperature inside the cooking equipment and achieving the effect of preserving the food inside the cooking equipment. Especially when the user uses the timed cooking function, the food can be preserved first, and then cooked after the preservation time is over, thereby improving the freshness of the food.

The first heat dissipation fin assembly 214 is connected to the outside of the air duct 1, the first cooling block 212 is connected to the air inlet channel 11 for cooling the gas in the air inlet channel 11, and the second cooling block 213 is connected to the air outlet channel 12 for cooling the gas in the air outlet channel 12. The hot air generated after the cooling and heat exchange between the first cooling block 212 and the second cooling block 213 is dissipated to the outside of the air duct 1 through the first heat dissipation fin assembly 214.

The air duct 1 has a first opening communicating with the air inlet channel 11 and a second opening communicating with the air outlet channel 12. The second heat dissipation fin group 232 passes through the first... The opening extends into the air inlet channel 11, allowing the heat of the airflow in the air inlet channel 11 to be exchanged through the second heat dissipation fin assembly 232. The second heat dissipation fin assembly 232 then exchanges heat with the first cooling block 212 through the heat dissipation body 231, thereby achieving the cooling effect on the gas in the air inlet channel 11. The third heat dissipation fin assembly 233 extends into the air outlet channel 12 through the second opening, allowing the heat of the airflow in the air outlet channel 12 to be exchanged through the third heat dissipation fin assembly 233. The third heat dissipation fin assembly 233 then exchanges heat with the second cooling block 213 through the heat dissipation body 231, thereby achieving the cooling effect on the gas in the air inlet channel 11.

[0057] Optionally, both the second heat dissipation fin group 232 and the third heat dissipation fin group 233 include multiple first heat dissipation fins 234 arranged sequentially along the airflow direction. An airflow channel 2301 is formed between two adjacent first heat dissipation fins. An air passage 230 is provided on the first heat dissipation fin 234 to connect two adjacent airflow channels 2301. The two adjacent air passages 230 are staggered. In this way, the length of the airflow channel 2301 can be extended, so that the heat exchange between the first heat dissipation fin and the airflow is more sufficient.

[0058] Optionally, the cooling assembly 2 further includes a first sealing member 24. The first sealing member 24 has a first clearance hole 241 corresponding to the first cooling block 212 and a second clearance hole 242 corresponding to the second cooling block 213. The first sealing member 24 is sandwiched between the cooling body 211 and the heat dissipation body 231. The first cooling block 212 passes through the first clearance hole 241 and abuts against the heat dissipation body 231. The second cooling block 213 passes through the second clearance hole 242 and abuts against the heat dissipation body 231. By setting the first sealing member 24, the gap between the first cooling block 212 and the first clearance hole 241, and the gap between the second cooling block 213 and the second clearance hole 242 are sealed, preventing airflow from flowing out through the gap between the first cooling block 212 and the first clearance hole 241, and the gap between the second cooling block 213 and the second clearance hole 242.

[0059] Optionally, the cooling assembly 2 further includes a second seal 25, which is disposed between the heat dissipation body 231 and the air duct 1 to seal the gap between the heat dissipation body 231 and the air duct 1, thereby preventing airflow from flowing out through the gap between the heat dissipation body 231 and the first opening and the gap between the heat dissipation body 231 and the second opening.

The first heat dissipation fin assembly 214 includes multiple spaced second heat dissipation fins. The multiple second heat dissipation fins extend from the first end of the housing 22 to the second end of the housing 22. When the cooling structure 21 is working, the cooling fan 3 works at the same time to discharge the heat in the first heat dissipation fin assembly 214 to the outside of the air duct 1 through the air outlet.
