[0002] In existing household appliances with steam cooking function (steam-bake all-in-one machine and steam-bake micro-bake all-in-one machine, etc.), after the user selects the steam function, the water in the water tank flows or is pumped into the evaporator, and the evaporator works to generate water vapor, and the water vapor is used to heat and cook the food in the cavity;
[0003] After cooking is finished, a certain amount of steam will remain in the cavity and cannot be eliminated quickly. On the one hand, the moment the user opens the door, a large amount of steam will come out, affecting the user experience; on the other hand, if the steam is not discharged in time, as the temperature in the cavity gradually cools down, condensation water will form inside the cavity under the steam, affecting the cooking experience of food processing.
[0004] Some current steam cooking appliances also have steam exhaust structures, but most of them are installed on the appliance body. Due to limited exhaust capacity, condensed water may still remain on the door, making it impossible for users to observe the cooking status of food inside the cavity through the door glass. Utility Model Content

[0029] Please combine Figure 1 as well as Figure 2 As shown, the present application first provides a door body exhaust structure, including a door body 10 and a blocking component 20 arranged in the door body 10. The door body 10 is provided with an exhaust channel, and the blocking component 20 can open or close the exhaust channel.
[0030] In the present application, an exhaust channel is opened in the door body 10 to discharge the steam inside the steam cooking appliance to the outside through the exhaust channel, so as to prevent the steam from gushing out and affecting the user experience when the user opens the door body 10. At the same time, the exhaust channel is opened in the door body 10, so that the steam inside the cavity can be directly discharged through the door body 10, thereby avoiding the residual steam on the side of the cavity close to the door body 10, which causes the steam to form condensation water on the door body 10, so that the user can directly observe the cooking situation of the food in the cavity through the glass door body 10, thereby further improving the user's cooking experience.
[0031] In addition, the exhaust channel is opened or closed by the sealing component 20. When the exhaust channel is closed, steam cooking can be carried out normally to prevent steam from overflowing through the exhaust channel and affecting the cooking effect. When cooking is completed, the exhaust channel is opened to exhaust and dehumidify, thereby optimizing the user's subsequent usage experience.
[0032] Preferably, the blocking assembly 20 can linearly control the opening size of the exhaust passage to change the exhaust capacity according to actual needs.
[0033] Please combine Figure 3 as well as Figure 4As shown, in some embodiments, the blocking assembly 20 includes a driving member and a blocking member 21 , and the driving member can drive the blocking member 21 to move in a direction perpendicular to the door body 10 to open or close the exhaust passage.
[0034] Of course, in some other embodiments, the blocking component 20 may also be other structures, such as a valve structure, etc., as long as it can open or close the exhaust channel as needed, and the present application does not make further limitations here.
[0035] In some embodiments, when the exhaust channel is closed, the blocking member 21 blocks the exhaust ports on both sides of the exhaust channel at the same time; blocking the exhaust ports on both sides of the exhaust channel at the same time can increase the sealing effect and prevent steam leakage during cooking.
[0036] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the door body 10 includes an inner door panel 11, an outer door panel 12 and an annular shielding cover 13, the shielding cover 13 is fixed between the inner door panel 11 and the outer door panel 12, and the inner door panel 11 and the outer door panel 12 are respectively provided with an inner exhaust port 11a and an outer exhaust port 12a to cooperate with the shielding cover 13 to form an exhaust passage.
[0037] The shielding cover 13 can prevent the steam from entering other positions in the door body 10, guide the steam, and ensure that the steam is discharged through the external exhaust port 12a.
[0038] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the outer exhaust port 12a corresponds to the shielding cover 13 in a contour, and the inner exhaust port 11a is smaller than the outer exhaust port 12a, so as to increase the exhaust flow rate at the position of the inner exhaust port 11a and improve the exhaust effect.
[0039] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the blocking member 21 includes a blocking plate 21a and a blocking column 21b. The blocking column 21b can be engaged with the inner exhaust port 11a, and the blocking plate 21a can be engaged with the outer exhaust port 12a.
[0040] When the exhaust passage is closed, the blocking member 21 will not protrude or recess relative to the door body 10 , and the outer door panel 12 and the inner door panel 11 are both complete planes to avoid dust accumulation at the protruding or recessed positions, while also increasing the aesthetics of the door body 10 .
[0041] Please combine Figure 4 as well as Figure 5As shown, in some embodiments, the driving member is an electromagnet 22 fixedly mounted on the door body 10, and a magnet 21c corresponding to the electromagnet 22 is fixedly mounted on the blocking member 21; since the internal space of the door body 10 is limited, relying on the attraction and repulsion characteristics between the electromagnet 22 and the magnet 21c, the blocking member 21 can be driven while occupying a small space, thereby reducing the thickness of the door body 10 as much as possible.
[0042] In some other embodiments, the driving member may also be a commonly used driving structure such as a motor, an electric push rod, a cylinder, etc., as long as it can drive the blocking member 21 to move to open and close the exhaust channel, and the present application does not make any further limitations here.
[0043] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the blocking assembly 20 further includes a bracket 23 fixed to the door body 10 , and the blocking member 21 is further fixed with a guide column 21 d slidably connected to the bracket 23 in a direction perpendicular to the door body 10 .

[0045] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the magnet 21c is fixed to the end of the guide post 21d.
[0046] Preferably, the bracket 23 and the electromagnet 22 are both fixed to the inner door panel 11 , and the magnet 21 c and the electromagnet 22 are both located inside the U-shape of the bracket 23 .
[0047] More preferably, the projection of the guide hole of the bracket 23 along the length direction of the guide post 21d is located inside the magnet 21c, that is, the magnet 21c can abut against the bracket 23 along the length direction of the guide post 21d to prevent the guide post 21d and the bracket 23 from falling out.
[0048] In some embodiments, the blocking component 20 includes a plurality of driving members, and the driving members are evenly distributed circumferentially around the blocking column 21 b to increase the movement stability of the blocking member 21 .
[0049] Preferably, the blocking assembly 20 includes two driving members.
[0050] A second aspect of the present application provides a steam cooking appliance, comprising an appliance body and the above-mentioned door exhaust structure, wherein the door 10 is hinged to the appliance body.
[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0052] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
