[0030] The following embodiments illustrate the present invention, but the present invention is not limited by these embodiments. Modifying the specific embodiments of the present invention or making equivalent replacements for 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.

[0031] Embodiment 1:

[0032] As Figures 1 to 5 shown, this embodiment provides a heat dissipation system for a cooking device. The cooking device has a cavity 1, including: a first air duct 2, the first air duct 2 having a first air inlet 21 and a first air outlet 22; a second air duct 3, the second air duct 3 having a second air inlet 31 and a second air outlet 32; a fan assembly 4, the air inlet end of the fan assembly 4 being connected to the first air outlet 22 and the air outlet end being connected to the second air inlet 31; a heat dissipation channel 5, the heat dissipation channel 5 being arranged on the cavity 1 for connecting the cavity 1, the first air duct 2 and the second air duct 3; a linkage mechanism 6, the linkage mechanism 6 being arranged on the heat dissipation channel 5, and by controlling the action of the linkage mechanism 6, the heat dissipation channel 5 is communicated with the first air duct 2 or the heat dissipation channel 5 is communicated with the second air duct 3.

[0033] In this embodiment, the cooking device can be a steam oven, a steamer or an oven. Of course, it can also be other types of cooking devices. The cooking device of this embodiment has a cavity 1 with one end open. A door body is installed at the open end of the cavity 1, and a housing is installed outside the cavity 1 for fixedly installing the cavity 1. The heat dissipation system includes a first air duct 2, a second air duct 3, a fan assembly 4, a heat dissipation channel 5 and a linkage mechanism 6. Among them, both the first air duct 2 and the second air duct 3 are installed outside the cavity 1. The first air duct 2 has a first air inlet 21 and a first air outlet 22. The first air inlet 21 is communicated with the outside, and the first air outlet 22 is communicated with the air inlet end of the fan assembly 4. The second air duct 3 has a second air inlet 31 and a second air outlet 32. The second air inlet 31 is communicated with the air outlet end of the fan assembly 4, and the second air outlet 32 is communicated with the outside. Thus, the first air duct 2 and the second air duct 3 are interconnected through the fan assembly 4. The heat dissipation channel 5 is arranged on the cavity 1 to connect the cavity 1, the first air duct 2 and the second air duct 3. The linkage mechanism 6 is fixedly installed on the heat dissipation channel 5. The cooking device controls the linkage mechanism 6 to act to connect the heat dissipation channel 5 and the first air duct 2, so that the steam in the cavity 1 flows into the first air duct 2, or connects the heat dissipation channel 5 and the second air duct 3, so that the steam in the cavity 1 flows into the second air duct 3. Its structure is simple, and it can quickly reduce the temperature and steam content in the cavity, thereby improving the user experience.

[0034] A first exhaust port 51 and a second exhaust port 52 are respectively opened on the heat dissipation channel 5. The first exhaust port 51 is communicated with the first air duct 2, and the second exhaust port 52 is communicated with the second air duct 3. Its structure is simple and the design is ingenious.

[0035] In the normal cooking state of this embodiment, the cooking device controls the linkage mechanism 6 to act to open the first air inlet 21. The linkage mechanism 6 acts synchronously to open the second exhaust port 52 and close the first exhaust port 51 at the same time. Thus, the external air is guided to the second air duct 3 through the fan assembly 4 to take the internal heat of the cooking device out of the cavity 1. At the same time, the heat dissipation channel 5 is communicated with the second air duct 3 through the second exhaust port 52 to make the steam in the cavity 1 flow into the second air duct 3. After cooking, the cooking device controls the linkage mechanism 6 to act to close the first air inlet 21. The linkage mechanism 6 acts synchronously to open the first exhaust port 51 and close the second exhaust port 52 at the same time. Thus, the heat dissipation channel 5 is communicated with the first air duct 2 through the first exhaust port 51, and the steam in the cavity 1 flows in the direction of the first air duct 2. The fan assembly 4 rotates to work to discharge the steam outwards after passing through the second air duct 3.

[0036] Further, the linkage mechanism 6 includes a door panel 61 rotatably disposed in the heat dissipation channel 5. By controlling the movement of the door panel 61, the heat dissipation channel 5 is connected to the first air duct 2 or the heat dissipation channel 5 is connected to the second air duct 3. Its structure is simple and the design is reasonable, which can further improve the heat dissipation capacity of the cavity.

[0037] Specifically, the area of the first exhaust port 51 is larger than the area of the second exhaust port 52. Its design is reasonable and ingenious, which can prevent a large amount of steam from being discharged from the second exhaust port during the cooking process.

[0038] In this embodiment, a first exhaust port 51 and a second exhaust port 52 are respectively formed on the heat dissipation channel 5. The first exhaust port 51 is connected to the first air duct 2, and the second exhaust port 52 is connected to the second air duct 3. The heat dissipation channel 5 has two opposite outer walls, and the second exhaust port 52 is symmetrically disposed on the two opposite outer walls. More preferably, the two opposite outer walls are both parallel to the direction in which the steam in the second air duct 3 flows. The second exhaust port 52 can also be disposed at a more appropriate position according to actual needs. At the same time, the area of the first exhaust port 51 is larger than the total area of the second exhaust port 52, which can further prevent a large amount of steam from being discharged from the second exhaust port 52 during the cooking process, so as to effectively improve the cooking ability of the cooking device.

[0039] Preferably, an air inlet door 23 is provided at the first air inlet 21 to open or close the first air inlet 21. Its structure is simple, which is convenient for controlling the opening and closing of the first air inlet.

[0040] Preferably, the linkage mechanism 6 includes a crankshaft 62 and a linkage rod 63. The crankshaft 62 is rotatably disposed on the heat dissipation channel 5. One end of the linkage rod 63 is connected to the air inlet door 23, and the other end is connected to the door panel 61 through the crankshaft 62. Its structure is simple and the design is reasonable. By simultaneously linking the door panel and the air inlet door to change the heat dissipation path of the cooking device, the cooking device can effectively achieve temperature-segmented cooking, and further make the cooking of food more refined.

[0041] Further, a driving motor 7 is further included. The output end of the driving motor 7 is connected to the air inlet door 23 to drive the air inlet door 23 to move. When the air inlet door 23 moves, it drives the door panel 61 to move synchronously through the linkage rod 63;

[0042] When the driving motor 7 drives the air inlet door 23 to move to open the first air inlet 21, the air inlet door 23 drives the door panel 61 to move to close the first exhaust port 51, and the heat dissipation channel 5 is connected to the second air duct 3;

[0043] When the driving motor 7 drives the air inlet door 23 to move to close the first air inlet 21, the air inlet door 23 drives the door panel 61 to move to open the first exhaust port 51, and the heat dissipation channel 5 is connected to the first air duct 2. Its structure is simple, compact and the design is reasonable.

[0044] Specifically, one end of the door panel 61 is connected to the crankshaft 62, and the other end is hinged to the heat dissipation channel 5. Its structure is simple, which further improves the reliability of the rotation of the door panel.

[0045] In this embodiment, an intake valve 23 is movably arranged at the position of the first air inlet 21. A driving motor 7 is arranged outside the cavity 1. The output end of the driving motor 7 is connected to the intake valve 23 to drive the intake valve 23 to open or close the first air inlet 21. The driving motor 7 can be a reduction motor or a stepping motor. Of course, a suitable driving motor can also be selected according to actual needs. The door panel 61 in this embodiment is preferably made of a metal material. It is also possible to make half of the door panel 61 of a plastic material and the other half of a metal material, so as to reduce the overall weight of the door panel 61. Of course, the door panel 61 can also be made of other more suitable materials. For the convenience of product processing, the intake valve 23 in this embodiment is made of a plastic material, but it is not limited to being made of a plastic material and can also be made of other more suitable materials.

[0046] The linkage mechanism 6 in this embodiment includes a door panel 61, a crankshaft 62 and a linkage rod 63 that are rotatably arranged in the heat dissipation channel 5. The crankshaft 62 is rotatably arranged on the heat dissipation channel 5 and is connected to the door panel 61 to control the movement of the door panel 61. One end of the linkage rod 63 is connected to the intake valve 23, and the other end is connected to the door panel 61 through the crankshaft 62. When the driving motor 7 drives the intake valve 23 to act, the door panel 61 is driven to move synchronously through the linkage rod 63. When the driving motor 7 drives the intake valve 23 to open the first air inlet 21, the door panel 61 is driven to close the first exhaust port 51 through the linkage rod 63 so that the heat dissipation channel 5 is communicated with the second air duct 3. Or when the driving motor 7 drives the intake valve 23 to close the first air inlet 21, the door panel 61 is driven to open the first exhaust port 51 through the linkage rod 63 so that the heat dissipation channel 5 is communicated with the first air duct 2, and the heat dissipation channel 5 is partitioned by the door panel 61 so that the cavity 1 is not communicated with the second air duct 3.

[0047] In the cooking device of this embodiment, when in the normal cooking state, the air inlet door 23 is opened to keep the first air inlet 21 always open. After the external air enters the first air duct 2 from the first air inlet 21, the external air is guided by the fan assembly 4 to the second air duct 3 to take the heat inside the cooking device out of the cavity 1. At the same time, the steam in the cavity 1 slowly discharges into the second air duct 3 through the second exhaust port 52 of the heat dissipation channel 5; after the cooking device finishes cooking, the cooking device needs to quickly reduce the temperature and steam content inside the cavity. The driving motor 7 is operated to drive the air inlet door 23 to close the first air inlet 21, and at the same time, the door panel 61 is driven by the linkage rod 63 to open the first exhaust port 51. The steam in the cavity 1 flows into the first air duct 2 from the first exhaust port 51, and then is guided by the fan assembly 4 to the second air duct 3 to quickly discharge the high-temperature steam in the cavity 1 out of the cavity 1.

[0048] One end of the door panel 61 in this embodiment is connected to the crankshaft 62, and the other end is hinged to the heat dissipation channel 5. Thus, the door panel 61 is rotatably arranged in the heat dissipation channel 5 around the hinge structure. The door panel 61 is driven by the linkage rod 63 to turn inward and upward to block the heat dissipation channel 5 to close the second exhaust port 52, so that the cavity 1 is communicated with the first air duct 2 through the first exhaust port 51, or the door panel 61 is turned downward to communicate the heat dissipation channel 5 and the door panel 61 closes the first exhaust port 51 at the same time, so that the cavity 1 is communicated with the second air duct 3 through the second exhaust port 52.

[0049] Furthermore, the first exhaust port 51 is arranged on the side of the heat dissipation channel 5 close to the fan assembly 4. Its structure is simple and the design is reasonable, which can further improve the heat dissipation efficiency of the cooking device.

[0050] Particularly, a partition 8 is arranged between the first air duct 2 and the second air duct 3 to separate the first air duct 2 and the second air duct 3. A seal 9 is arranged at the connection between the heat dissipation channel 5 and the partition 8. Its structure is simple and can effectively improve the airtightness between the first air duct and the second air duct.

[0051] In this embodiment, after cooking is completed, in order to quickly discharge a large amount of high-temperature steam, preferably, the first exhaust port 51 is opened on the side of the heat dissipation channel 5 close to the fan assembly 4. Of course, it can also be opened on any side of the heat dissipation channel 5. In this embodiment, a partition 8 is provided outside the cavity 1 to vertically separate the first air duct 2 and the second air duct 3. A seal 9 is provided at the junction of the heat dissipation channel 5 and the partition 8. Thus, the seal 9 is sleeved around the periphery of the heat dissipation channel 5 to further improve the airtightness between the first air duct 2 and the second air duct 3, preventing the air in the second air duct 3 from flowing back to the first air duct 2. At the same time, the seal 9 can further improve the stability of the fixed installation of the heat dissipation channel 5. The cooking device in this embodiment is an embedded type, but is not limited to the embedded cooking device. It can also be applied to other types of cooking devices according to actual needs. To facilitate the ventilation of the cavity 1, the first air inlet 21 and the second air outlet 32 of the embedded cooking device are both provided at the position close to the upper edge of the open front end of the cavity 1. Of course, the first air inlet 21 and the second air outlet 32 can also be arranged at other more suitable positions of the cooking device according to actual needs.

[0052] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several deformations and improvements can be made, and these all belong to the protection scope of the present invention.
