Description

Technical Field

[0001] The utility model relates to the field of cooking devices, in particular to a door structure for a cooking device, a cooking device and an integrated stove. Background Art

[0002] The door handles of existing cooking devices (e.g., steamers, ovens, steam-and-bake all-in-one machines, etc.) are generally protruding on the front of the door body. Due to the limited kitchen space, the protruding handles will take up extra kitchen space. In addition, the protruding handles are easy to bump into the user. Since the handles are generally made of metal and have edges and corners, the user will suffer certain trauma after bumping into them, causing safety hazards. At the same time, heavy objects hitting the handles are also the main reason for the shattering of the door glass. For example, the Chinese utility model patent with patent number ZL202221406462.X (authorization announcement number CN217390520U), the Chinese utility model patent with patent number ZL202221161561.6 (authorization announcement number CN217338306U), etc.

[0003] Furthermore, when the cooking device is in working state, the interior of the inner pot is in a high temperature state (especially in the baking mode), and the high temperature in the inner pot is radiated to the door body, causing the door body temperature to rise, posing a risk of scalding the user. At the same time, it will cause the handle on the door body to heat up, so that the user is at risk of being scalded when opening and closing the door. Summary of the invention

Since the embodiments disclosed in the present utility model can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0034] like Figures 1 to 7 As shown, an integrated stove comprises a stove 1 and a cooking device 2, wherein the cooking device 2 is arranged below the stove 1. In this embodiment, the cooking device 2 is specifically a steam oven. The cooking device 2 comprises a door structure, wherein the door structure comprises a door 3, wherein the door 3 is used to cover the front opening of the inner pot 20 of the cooking device 2. A handle window 31 is arranged on the front of the door 3, wherein a cover plate 4 capable of shielding the handle window 31 is rotatably installed in the handle window 31, and when the cover plate 4 shields the handle window 31, the front of the cover plate 4 is flush with the front of the door 3. A heat dissipation fan 5 is also included, wherein a heat dissipation cavity 8 is arranged in the door 3, wherein the heat dissipation cavity 8 comprises a heat dissipation outlet 82 and a cold air inlet 81 which are fluidly connected with the air inlet of the heat dissipation fan 5, and the handle window 31 is located on the heat dissipation cavity 8.

[0035] As can be seen from the above, in the present invention, a cover plate 4 is rotatably installed in the handle window 31, and the cover plate 4 can cover the handle window 31. By rotating the cover plate 4 in this way, the door opening and closing action can be achieved by holding the cover plate 4 or the edge of the handle window 31 by hand, and the front appearance of the door body 3 can be made beautiful by covering the handle window 31 by the cover plate 4. In addition, when the cover plate 4 covers the above handle window 31, the front of the cover plate 4 is flush with the front of the door body 3, which can make the front appearance of the door body 3 more beautiful on the one hand, and solve the bumping problem caused by the convex setting of the handle in the prior art on the other hand. Further, a heat dissipation cavity 8 having a cold air inlet 81 and a heat dissipation outlet 82 is provided in the door body 3, and the heat dissipation outlet 82 of the heat dissipation cavity 8 is fluidly connected with the air inlet of the above heat dissipation fan 5, and the above handle window 31 is located on the above heat dissipation cavity 8. In this way, when the cooling fan 5 is in working state, cold air enters the cooling cavity 8 through the cold air inlet 81, and then takes away the heat in the cooling cavity 8 through the cooling outlet 82. Since the handle window 31 is located on the above-mentioned cooling cavity 8, the cover plate 4 and the edge of the handle window 31 can be cooled to prevent the user from being burned when opening and closing the door.

[0036] Furthermore, the handle window 31 has a gripping portion 3111 on the edge thereof for holding the door. The gripping portion 3111 can effectively ensure the reliability of the door opening and closing operation. A gap is left between the gripping portion 3111 and the corresponding side edge of the cover plate 4 to form the cold air inlet 81 of the heat dissipation cavity 8. In this way, cold air can enter the heat dissipation cavity 8 through the cold air inlet 81, and at the same time, it can take away the heat at the gripping portion 3111, thereby achieving heat dissipation of the gripping portion 3111 and preventing the user from being scalded when opening and closing the door.

In this way, the heat dissipation fan 5 can simultaneously drive the heat radiated in the interlayer 30 when it is in operation, realize the heat dissipation of the door body 3, and avoid the high temperature of the outer surface of the door body 3 to burn the user when the cooking device 2 is in operation.

[0040] Furthermore, a base 7 is sandwiched in the interlayer 30 along the left-right direction, and the base 7 and the bracket 6 form the heat dissipation cavity 8 above and below, so that the heat dissipation cavity 8 can be formed well, and the bracket 6 has a rear side wall extending vertically along its own length direction, and the rear side wall is placed on the top of the inner door plate 3b along the length direction, and the heat dissipation outlet 82 and the ventilation outlet 63 are both opened on the rear side wall of the cover bracket 6, and the heat dissipation fan 5 is arranged on the inner liner 20. Therefore, the bracket 6 can be stably covered on the upper port of the interlayer 30, and under the drive of the heat dissipation fan 5, the cold air can smoothly enter the heat dissipation cavity 8 through the cold air inlet 81, and the mixed gas after the cold air and the hot air are mixed can also be smoothly discharged from the heat dissipation cavity 8 through the heat dissipation outlet 82, thereby improving the heat dissipation efficiency of the heat dissipation cavity 8, and then improving the heat dissipation effect of the gripping part 3111. In this embodiment, a heat dissipation channel 50 is provided on the inner tank 20 , the heat dissipation fan 5 is installed on the air outlet port of the heat dissipation channel 50 , and the air inlet port of the heat dissipation channel 50 is fluidically connected with the heat dissipation outlet 82 and the ventilation outlet 63 .

[0041] Specifically, the bracket 6 is a cover body with an open bottom, and the front side of the cover body is recessed from front to back along the middle of its own length direction to form a groove 61 extending left and right, and the lower end of the groove 61 extends through the cover opening of the cover body. The top edge of the outer door panel 3a is recessed to form a notch 311, and the groove 61 and the base 7 are buckled up and down to form the heat dissipation cavity 8, and the front end of the top groove wall of the groove 61 and the notch 311 form the handle window 31, and the heat dissipation outlet 82 is opened on the rear side groove wall of the groove 61. In this way, the cover plate 4, the groove 61 and the base 7 can stably form the heat dissipation cavity 8.

[0042] Preferably, there are two ventilation outlets 63, which are respectively arranged on the left and right sides of the heat dissipation outlet 82, so as to improve the heat dissipation efficiency of the door body 3 and better prevent the high temperature on the surface of the door body 3 from scalding the user. In addition, the base 7 is a box body with an upper opening. In this way, foreign objects falling from the notch 311 can be collected in the base 7, so as to prevent the inside of the door body 3 from being contaminated, and the foreign objects collected in the base 7 are convenient for users to clean.
