Description

Technical Field

[0001] The utility model relates to the field of cooking equipment, in particular to a cooking liner structure and a steaming and baking all-in-one machine. Background Art

[0002] The steam-bake combination machine is a cooking device that has both steaming and baking functions. As one machine integrates multiple cooking functions, it is becoming more and more popular in the market. For example, the Chinese utility model patent with patent number ZL202222890018.6 (authorization announcement number CN219206521U) and the Chinese utility model patent with patent number ZL 202222716891.3 (authorization announcement number CN219206606U).

[0003] Furthermore, the steam-bake machine uses a heating system to achieve radiation heating and hot air circulation heating of food. The heating system includes an upper heating tube, a side heating tube, a lower heating tube and a hot air blower, wherein the upper heating tube is installed on the top wall of the inner pot, the side heating tube is arranged around the outer periphery of the impeller of the hot air blower, and the lower heating tube is installed on the bottom wall of the inner pot. The wiring terminals of each heating tube are passed through the mounting holes of the inner pot wall. In order to ensure the sealing of the inner pot in the steaming mode, a sealing ring is used to seal it. In order to ensure cooking safety, the sealing ring is generally made of food-grade silicone rubber with a temperature resistance of more than 250°C. When the steam-bake machine fails and the software fails, it may cause the hot air blower to stop rotating, while the side heating tube continues to work. After a few minutes, the temperature at the sealing ring can reach more than 600°C, and the sealing ring will catch fire and carbonize into white powder, causing a safety hazard. Summary of the invention

[0004] The first technical problem to be solved by the utility model is to provide a cooking liner structure with good sealing performance and good safety in use in view of the prior art.

[0005] The second technical problem to be solved by the present invention is to provide a steam-bake all-in-one machine with the above cooking liner structure in view of the prior art.

[0006] The technical solution adopted by the utility model to solve the first technical problem is: a cooking inner pot structure, including an inner pot, a side heating tube and a sealing ring, wherein the connection terminal of the side heating tube is inserted into the mounting hole of the side wall of the inner pot, and the sealing ring is used to seal the mounting hole, and is characterized in that the side wall of the inner pot where the mounting hole is located is convex to form a mounting groove on the inner side surface of the inner pot, the sealing ring is accommodated in the mounting groove, and the notch of the mounting groove is covered with a heat insulation sheet.

[0007] Furthermore, the sealing ring is in the shape of a plate, and a through hole is provided on the plate body of the sealing ring for the connection terminal of the side heating tube to pass through, and the periphery of the plate body extends along its own length toward the rear groove wall of the mounting groove to form a first peripheral edge, and the first peripheral edge abuts against the rear groove wall of the mounting groove along its own length direction to enclose a first heat dissipation cavity, and the mounting hole is located in the first heat dissipation cavity, and a first heat dissipation hole is provided on the rear groove wall of the mounting groove, which communicates with the outside and is located in the first heat dissipation cavity. In this way, the heat at the sealing ring can be dissipated outward from the first heat dissipation cavity through the first heat dissipation hole, avoiding heat accumulation at the sealing ring, and better avoiding the influence of high heat on the sealing ring.

[0008] Furthermore, the heat insulation sheet is sandwiched between the sealing ring and the flange of the side heating tube, so that the heat insulation sheet can be stably arranged, and the periphery of the sealing ring extends along its own length toward the heat insulation sheet to form a second periphery, and the second periphery abuts against the heat insulation sheet along the length direction to enclose a second heat dissipation cavity, and the second heat dissipation cavity is connected with the first heat dissipation cavity through the second heat dissipation hole provided on the heat insulation sheet. In this way, the first heat dissipation cavity and the second heat dissipation cavity that are connected are formed on both sides of the sealing ring, so that the heat on both sides of the sealing ring can be dissipated outward through the first heat dissipation hole, thereby improving the heat dissipation effect on the sealing ring.

[0009] Furthermore, the sealing ring is in the shape of a long plate and is arranged along the left and right directions of the inner tank. The sealing ring has reinforcing ribs protruding from the two side plate surfaces in the middle of the length direction, and the reinforcing ribs on each side are arranged in the corresponding heat dissipation cavity along the length direction of the sealing ring. The structural strength of the sealing ring can be improved by providing the reinforcing ribs, and the sealing effect of the sealing ring on the mounting hole can be improved.

[0010] Furthermore, the flange, the heat insulating sheet, the sealing ring and the side wall of the inner tank of the side heating pipe are connected in sequence through a fixing piece, and a fixing hole for the fixing piece to pass through is provided on the sealing ring, so that the side heating pipe, the heat insulating sheet and the sealing ring can be stably installed.

[0011] Furthermore, the side heating tube has two connection terminals, and accordingly, the through holes also have two connection terminals, one corresponding to each connection terminal, and the two through holes are arranged at intervals in the middle of the sealing ring along the length direction of the sealing ring;

[0012] There are two fixing parts, and correspondingly, there are two fixing holes, which correspond to the fixing parts one by one.

Thus, the heat in the inner tank can be better isolated from the sealing ring, thereby better preventing the sealing ring from being damaged or even catching fire.

[0016] Furthermore, the flange of the side heating pipe has a larger area than the heat insulation sheet and can completely cover the heat insulation sheet, which can ensure a stable installation of the heat insulation sheet and better prevent high temperature heat from being transferred to the sealing ring.

[0017] Furthermore, the heat insulation sheet is a mica sheet, which has high temperature resistance and good heat insulation performance, and can effectively reduce the heat transferred to the sealing ring.

[0018] The technical solution adopted to further solve the above-mentioned second technical problem is: a steam-bake machine, characterized in that it includes the cooking liner structure as described above.

The sealing ring 3 is accommodated in the mounting groove 11, and a heat insulation sheet 4 is provided on the notch of the mounting groove 11.

[0030] As can be seen from the above, the utility model is provided with a mounting groove 11, the sealing ring 3 is accommodated in the mounting groove 11, and the groove cover of the mounting groove 11 is provided with a heat insulating sheet 4, so that the sealing ring 3 is accommodated in a closed space surrounded by the heat insulating sheet 4 and the mounting groove 11, and the high temperature is isolated from the sealing ring 3, and the heat is prevented from being transferred to the sealing ring 3, thereby preventing the sealing ring 3 from being damaged by high temperature, and especially preventing the sealing ring 3 from catching fire in an abnormal situation and when the hot air blower 6 stops rotating, thereby ensuring safety in use.

[0031] In this embodiment, specifically, the side wall of the inner liner 1 is the left side wall of the inner liner 1, a hot air blower 6 is installed on the left side wall, and a hot air baffle 7 is provided on the inner surface of the left side wall to form a hot air chamber 70.
