Double-layer inner box structure of electric oven

Abstract

The double-layer inner box structure of the electric oven mainly consists of a roasting layer and a box layer. The roasting layer is composed of a furnace surface and a vertical surface at the oven mouth of the electric oven. Food is roasted on the roasting layer. The inside of the vertical surface of the roasting layer is the box layer. There is a gap between the vertical surface and the box layer. The oil and water of the roasted food, the boiled and splashed oil and water during roasting, and the oil and water condensed by oil fume do not flow to the box layer or drip on the pipe head of the electric heating pipe, but directly drip on the oil and water collecting tray at the lower part of the oven. Thus, the box layer is rarely contaminated, and the joint where the electric heating pipe is installed on the box layer and the pipe head of the electric heating pipe are also rarely contaminated. The replacement of the electric heating pipe is not difficult. In order to increase the rigidity of the roasting layer and prevent high-temperature deformation, a folded edge is arranged along the lower edge of the roasting layer. In order to prevent the inward seepage of oil and water at the folded edge, the angle of the folded edge is set as an acute angle.

Description

Technical Field

[0001] The double-layer inner casing structure of the electric oven is a double-layer structure that avoids oil contamination of the inner casing and heating element installation area during grilling. It belongs to the cookware field. Background Technology

[0002] The existing electric ovens have a single-layer cylindrical inner casing. During grilling, the oil and water from the food itself, the oil and water that splatter during grilling, and the oil and water that condense from the fumes produced during grilling all flow from top to bottom, thus contaminating the entire inner casing of the electric oven. In particular, the oil and water condenses at the joint where the heating element is installed in the inner casing, and at the tip of the heating element. It can even solidify into a substance that seals the joint, making it difficult to replace the heating element. Summary of the Invention

[0003] The double-layer inner casing structure of the electric oven features a spaced-out double-layer design. The grilling layer consists of a grill surface and a vertical surface. Inside the vertical surface of the grilling layer is the casing layer, where the heating element is installed. The gap between the grilling layer and the casing layer prevents oil and water from the food itself, oil and water splashing during grilling, and oil and water condensed from fumes from flowing into the casing layer. Instead, the oil and water drips directly into the drip tray at the bottom of the oven. This reduces contamination of the entire casing layer, especially at the junction of the heating element and the casing layer, as well as at the tip of the heating element, making heating element replacement easier.

[0004] To increase the rigidity of the grilling layer and prevent it from deforming at high temperatures, a folded edge is provided at the bottom edge of the grilling layer. To prevent oil and water from seeping inward through the folded edge, the angle between the folded edge and the vertical plane is set to an acute angle.

[0005] The double-layer inner chamber structure of the electric oven effectively avoids the aforementioned defects of the existing technology.

[0006] The double-layer inner box structure of the electric oven is achieved through the following scheme: The oven opening of the electric oven with the double-layer inner box structure is a grilling layer (3) composed of a grill surface (1) and a vertical surface (2). Inside the vertical surface (2) of the grilling layer (3) is the box layer (5). The heating tube (8) is installed in the box layer (5). There is a gap (6) between the box layer (5) and the vertical surface (2) of the grilling layer (3). The distance of the gap (6) is between 5 mm and 12 mm.

[0007] The electric oven has a double-layer inner box structure. The lower edge of the vertical surface (2) of the grilling layer (3) is provided with a folded edge (9), and the angle between the folded edge (9) and the vertical surface (2) is set to an acute angle. Attached Figure Description

[0012] The electric grill has a double-layered inner box structure. The grill opening consists of a grilling layer 3, which is composed of a grill surface 1 and a vertical surface 2. Food can be grilled on the grill surface 1 (skewers 10), on the grilling rack 4 set on the grill surface 1, or on the grilling rack 4 set on the vertical surface 2. Inside the vertical surface 2 of the grilling layer 3 is the box layer 5, where the heating element 8 is installed. There is a gap 6 between the box layer 5 and the vertical surface 2 of the grilling layer 3. The gap 6 is between 5 mm and 12 mm. The gap 6 prevents the oil and water from the food itself, the oil and water that splashes during grilling, and the oil and water that condenses from the fumes from flowing into the box layer 5 or dripping onto the tip of the heating element 8. Instead, the oil and water drips directly into the drip tray 7 at the bottom of the grill, avoiding contamination of the box layer 5, the joint where the heating element 8 is installed in the box layer 5, and the tip of the heating element 8. This also makes it easier to replace the heating element 8.

[0013] To increase the rigidity of the grilling layer 3 and prevent it from deforming at high temperatures, a folded edge 9 is provided at the lower edge of the grilling layer 3. The folded edge 9 also serves to maintain the distance between the vertical surface 2 of the grilling layer 3 and the box layer 5. To prevent oil and water from seeping inward through the folded edge 9, the angle between the folded edge 9 and the vertical surface 2 is set to an acute angle.

[0014] The double-layer inner chamber structure of the electric oven effectively avoids the shortcomings of existing technologies.
