Specific embodiments

[0028] The following embodiments are used to illustrate the present invention, but the present invention is not limited by these embodiments. Modifying the specific implementation manner of the present invention or equivalently replacing some technical features without departing from the spirit of the present invention scheme shall all be covered within the scope of the technical solution claimed by the present invention.

[0029] Refer to Figures 1-5 , this embodiment provides a heat dissipation system, which includes an equipment body 1, a door body assembly 2, a fan assembly 3 and a control assembly 5. The equipment body 1 is provided with an inner tank 11 with one side open, a condensation chamber 101, an air inlet 102 and an exhaust port 103. The condensation chamber 101 is located above the inner tank 11 and is respectively connected to the air inlet 102 and the exhaust port 103. In this embodiment, the air inlet 102 is composed of a plurality of air inlet holes arranged at intervals in the left - right direction. In other embodiments, adjacent air inlet holes can be connected to make the air inlet 102 an elongated hole.

[0030] The door body assembly 2 is arranged on the equipment body 1 and is used to open or close the inner container 11. The door body assembly 2 is provided with a heat dissipation cavity 201, an air inlet 202 and an air outlet 203. In this embodiment, the air outlet 203 and the air inlet 202 are respectively arranged at the upper and lower ends of the door body assembly 2. The air outlet 203 is composed of a plurality of air outlet holes arranged at intervals in the left-right direction. The plurality of air outlet holes are in one-to-one correspondence with and communicated with a plurality of air inlet holes. In other embodiments, adjacent air outlet holes can be communicated with each other so that the air outlet 203 is in the shape of a long strip hole. The lower end of the heat dissipation cavity 201 is communicated with the external atmosphere through the air inlet 202, and the upper end of the heat dissipation cavity 201 is communicated with the air inlet 102 through the air outlet 203. The fan assembly 3 is arranged on the equipment body 1 and is electrically connected to the control assembly 5. The suction port of the fan assembly 3 is communicated with the condensation cavity 101 through the exhaust port 103, and the exhaust port of the fan assembly 3 is communicated with the external atmosphere.

[0031] Thus, when the fan assembly 3 works, external air can flow into the heat dissipation cavity 201 from the air inlet 202 at the lower end of the door body assembly 1, then flow into the condensation cavity 101 through the air outlet 1203 and the air inlet 102 in sequence, and finally be extracted and discharged by the fan assembly 3, thereby forming a heat dissipation air duct, which is convenient to use external air to cool the door body assembly 2 and effectively prevent the door body assembly 2 from overheating and hurting people.

[0032] Furthermore, the heat dissipation system further includes a temperature measuring component (not shown in the figure) and / or a humidity sensor 41. The temperature measuring component is arranged in the heat dissipation cavity 201 and is connected to the door body assembly 2 for real-time detection of the internal temperature of the heat dissipation cavity 201. See Figure 4 . The humidity sensor 41 is arranged in the condensation cavity 101 for real-time detection of the internal humidity of the condensation cavity 101. The control assembly 5 is electrically connected to the temperature measuring component and the humidity sensor 41 respectively. The control assembly 5 is used to control the on-off of the fan assembly 3 according to the internal temperature and / or the internal humidity.

[0033] When the internal temperature is greater than the preset temperature threshold T, the fan assembly 3 is started to extract the hot air inside the heat dissipation air duct and discharge it; otherwise, when the internal temperature is less than the preset temperature threshold T, the fan assembly 3 is turned off. When the internal humidity is greater than the preset humidity threshold R, the fan assembly 3 is turned off and the cooking equipment will also stop working; otherwise, when the internal humidity is less than the preset humidity threshold, the fan assembly 3 can be normally started. Thus, compared with the existing steam oven that defaults to turn on the fan assembly for heat dissipation when starting, this embodiment can control the on-off of the fan assembly 3 according to the internal temperature of the door body assembly 2 and / or the internal humidity of the condensation cavity 101, saving energy while solving the problems that the existing steam oven cannot detect the internal temperature of the door body assembly and the problem of leaking steam at the position of the door body assembly.

[0048] When the internal humidity of the condensation cavity is greater than R, steam leakage will occur inside the inner container 11, and the cooking device will stop working. At this time, the baffle component 6 will close, and the fan component will also stop working.

[0049] This embodiment also provides a cooking device, which can be any one of a steam box, an oven, a steam oven or an integrated stove with a steaming function. The cooking device has a heat dissipation system as described above.
