A second air inlet 341 communicating with the outside is provided on the built-in exposed surface, and air outside the cabinet can be introduced into the cooking cavity 100 through the second air inlet 341.

The exhaust structure includes an exhaust mechanism connecting the first air inlet and the second air inlet 341, and the exhaust mechanism can generate an airflow flowing from the second air inlet 341 towards the first air inlet after being started.

After the steaming function is finished, the steam exhausting mechanism is started, and outside air enters the cooking cavity 100 to extrude steam in the cooking cavity 100. Since the air drawn by the steam exhaust mechanism comes from the second air inlet 341, and the second air inlet 341 is located at the embedded exposed surface, which is the surface of the exhaust structure exposed to the outside after being embedded in the cabinet, it is ensured that the air entering the cooking cavity 100 via the steam exhaust mechanism is flowing air outside the apparatus. Compared with the air in the interior of the equipment or the cabinet, the external air is blown into the cooking cavity 100 from the air exhaust mechanism better, so that the air in the interior of the cabinet or the equipment is cleaner and more acceptable to users than the air in the interior of the equipment is blown into the cooking cavity 100.

In one embodiment, the embedded exposed surface of the housing is provided with a door body forming the cooking cavity 100 and a control panel; the second air inlet 341 is located between the control panel and the closed door.

The embedded exposed surface of the shell can be the front surface of the equipment, the openable door body is positioned below the control panel, the lower edge of the door body is hinged with the shell, and the door body is opened and closed in a rotating mode. A certain gap is formed between the closed door body and the control panel, the second air inlet 341 is located at the position of the gap, and air is introduced through the gap.

In other embodiments, the recessed exposed surface may include other sides beyond the front surface after the vent structure is recessed into the cabinet.

In one embodiment, the housing includes a top plate 310; the upper surface of the top plate 310 is provided with a cover plate 320, and the cover plate 320 and the top plate 310 enclose an air inlet duct 340; one end of the air inlet duct 340 is opened to form a second air inlet 341; the exhaust mechanism is connected with the other end opening of the air inlet duct 340.

The top plate 310 has a planar plate-like structure. The cover plate 320 is approximately box-packed and is provided with a top and coamings positioned around the top, the top is vertically spaced from the top plate 310, and the lower edge of the coamings is connected with the top plate 310, so that the cover plate 320 and the top plate 310 enclose an air inlet duct 340; the coaming plate positioned in front of the cover plate 320 is provided with an opening to form a second air inlet 341; the top of the cover plate 320 is opened so as to communicate with the steam exhaust mechanism.

The exhaust structure further includes a heat dissipation fan 360 and a heat dissipation air duct 350, where the heat dissipation fan 360 is used to dissipate heat generated by the electrical components in the structure. The heat dissipation air duct 350 may extend in the front-rear direction, and a rear end opening of the heat dissipation air duct 350 is connected to the heat dissipation fan 360, and a front end opening forms a second air outlet communicating with the outside. The air inlet duct 340 is located at the left or right side of the heat dissipation duct 350, and when the air inlet duct 340 is two, the two air inlet ducts 340 may be located at the left and right sides of the heat dissipation duct 350, respectively.

The cavity formed by the cover plate 320 and the top plate 310 is divided into two independent parts by the partition plate 330, wherein one part of the space forms an air inlet duct 340, and the other part of the space forms a heat dissipation duct 350. The volume of the air inlet duct 340 is much smaller than that of the heat dissipation duct 350, the heat dissipation duct 350 is used for dissipating heat from the top of the cooking cavity 100, the heat dissipation fan 360 can be located at a rear position, the heat dissipation fan 360 generates airflow from the rear to the front, and heat radiated by the top plate 310 is taken away by the airflow generated by the heat dissipation fan 360, so that the heat is blown out from the second air outlet.

As shown in fig. 1-3, in one embodiment, the steam extraction mechanism includes: a blower 240; an air pipe 210 connecting the blower 240 and the first air inlet; a first valve 220 connected between the blower 240 and the air pipe 210. The blower 240 is connected to the cover plate 320.

Blower 240 is mounted on top of cover plate 320, and may be connected using screws; because the aperture of the air outlet of the existing blower 240 is not matched with the diameter of the air pipe 210, an adapter 230 may be provided between the air outlet of the blower 240 and the air pipe 210. The air pipe 210 may be fixedly installed on the outer sidewall of the cooking cavity 100, and in this embodiment, the first air inlet is located on the left sidewall of the cooking cavity 100, and the air pipe 210 is also disposed on the left sidewall of the cooking cavity 100. A first valve 220 is further provided between the air pipe 210 and the adaptor 230, and whether the cooking cavity 100 is communicated with the outside is achieved by opening and closing the first valve 220. During the steaming function, the first valve 220 is closed, and steam in the cooking cavity 100 does not reversely flow out of the second air inlet 341, thereby avoiding a reduction in steaming efficiency.

In this embodiment, the fan 240 is disposed on the cover plate 320 to avoid the fan 240 being disposed on the top plate 310 to occupy the space of the top plate 310. The cover plate 320 can thus be made wide enough in the left-right direction to increase the width of the second air inlet 341.

In one embodiment, the second air outlet is located on the embedded exposed surface, and the air flow with heat is directly discharged to the outside, so that wind resistance can be reduced, and heat dissipation efficiency is improved.

In one embodiment, the first air outlet is connected with the air outlet pipe 400, and the air outlet direction of the air outlet pipe 400 can be changed, so that the steam discharging direction is more reasonable. Further, the number of the exhaust pipes 400 is at least two, and increasing the number of the exhaust pipes 400 can improve the exhaust efficiency.

Likewise, to avoid steam loss when the steaming function is started, a second valve is provided between the exhaust pipe 400 and the first air outlet.

The first air inlet and the first air outlet are respectively positioned at two opposite sides of the cooking cavity 100, which is beneficial to easier discharge of steam in the cooking cavity 100.

As shown in fig. 2, the steam exhaust mechanism and the exhaust pipe 400 are respectively located at the left side and the right side of the heat dissipation air duct 350, the heat dissipation air duct 350 is located at the middle position of the structure in the left-right direction, and the steam exhaust mechanism and the exhaust pipe 400 are respectively located at the left side and the right side of the heat dissipation air duct 350, so that the air inlet and the air outlet related components can be separated, the modularization processing is facilitated during assembly, and the interference of each component caused by centralized installation is avoided.
