DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with specific embodiments.

[0024] refer to Figure 1-5, an inner tank structure of an oven or a steam oven, comprising a box shell 1 and an inner tank cavity 2, wherein both sides of the inner tank cavity 2 are provided with a cavity 3 for uniform temperature, a fan 4 and a driver for driving the fan to rotate are provided in the cavity 3, a side plate 5 is provided between the cavity and the inner tank cavity 2, and at least one first air hole 6 is provided at a position corresponding to the fan on the side plate 5; at least one second air hole 7 is provided at a periphery of the side plate 5 or at a position corresponding to the outer periphery of the fan, and a positioning structure 8 for installing a partition 9 provided in the inner tank cavity is provided on the side of the side plate 5 close to the inner tank cavity.

[0025] The first air hole 6 is an annular air hole, and the second air hole 7 is a longitudinal or transverse strip air hole. The driver for driving the fan to rotate can be a driving motor, which is arranged outside the cavity 3. The first air hole 6 is arranged at the corresponding position of the fan, and the coverage area of ​​the first air hole 6 can be a circle corresponding to the size of the fan.

[0026] Here, it is defined that the fan can rotate forward to inhale air or reverse to blow air. The forward and reverse directions are not used as limitations of this patent, but only express two opposite directions. When rotating forward, since the first air hole 6 is close to the fan, a negative pressure is formed at the blowing part of the fan, and the air inside the inner cavity 2 of the liner is sucked into the cavity 3 from the first air hole 6. Since the space of the cavity 3 is small, after inhaling enough air, the second air hole 7 is far away from the fan, and the gas will be discharged from the second air holes 7 around. After one cycle, the heat in the air is exchanged, which can make the temperature of the discharged gas more uniform, thereby achieving the effect of uniform temperature; when rotating reversely, since the first air hole 6 is close to the fan and faces the fan, the fan blows the air inside the cavity 3 from the first air hole 6 to the inner cavity 2 of the liner, and the air at the second air hole 7 far away from the fan forms a negative pressure, and air is sucked from the inner cavity 2 of the liner into the cavity 3, thereby achieving the effect of uniform temperature.

[0027] Existing ovens or steam ovens generally have only one heating tube. If the air is not circulated enough, the temperature inside the inner chamber of the inner tank will be uneven, and the baked food will not be good. Therefore, the utility model is provided with two cavities 3 for uniform temperature, which are respectively arranged on both sides of the inner chamber 2 of the inner tank. Air is sucked in and discharged from both sides, so that the temperature of the entire inner chamber 2 of the inner tank becomes uniform, and the effect of steaming or baking food is better.

[0028] In addition, the cavity 3 with uniform temperature is arranged on both sides, which has a better effect than the top, because the cross-section of the top of a general oven or steam oven is larger, the left and right length is longer, the size of the fan is limited, and the position of air suction or blowing is limited by the size of the fan, so that the effect of air convection in the inner cavity of the inner tank is only relatively local convection, and the baking tray or grill in the inner cavity 2 of the inner tank is usually arranged in layers up and down, and the upper baking tray or grill will block the air convection, so that the inner cavity 2 of the inner tank is heated unevenly. Therefore, the convection formed by the cavity 3 and the fan on the left and right sides can pass through the gap between the layered baking trays or grills, so that the inner cavity 2 of the inner tank is heated more evenly. The convection of the upper and bottom of the oven is obviously not as good as that of the cavity 3 on both sides. The cavity 3 is arranged on the opposite sides to blow or inhale, so that the gas in the entire inner cavity of the inner tank moves and circulates, forming convection, which has a better effect and the temperature of the inner cavity of the inner tank is more uniform.

[0029] An annular heating pipe 14 is provided in the cavity 3 at a position corresponding to the fan 4. Of course, the utility model can also be based on the structure of an existing oven or steam oven with a heating pipe provided on the top. The heating pipes on both sides work together with the heating pipes on the top for heating. Preferably, the fan is arranged on the side of the fan 4 close to the side plate 5, and a heating pipe is provided to heat the inhaled air and then discharge it or directly discharge the heated gas, so that the overall heating effect of the inner cavity of the liner is better. The heating pipes of the existing oven or steam oven are generally arranged at the upper end, and two heating pipes are added on both sides, which is equivalent to heating pipes on three sides. In combination with the fan 4, not only the temperature is uniform, but also the heating efficiency is higher.

[0030] The cavity 3 is arranged in the interlayer between the box shell 1 and the inner chamber 2 of the inner tank, and a cover plate 10 is arranged outside the cavity 3. The cover plate 10 is provided with a mounting plate 12 for mounting a heating pipe 14 and corresponding mounting holes.

[0031] The positioning structure 8 is a groove or a boss that matches the partition 9. The positioning structure 8 needs to cooperate with the partition 9 to position the partition 9. The inner cavity of the oven or steam oven is generally provided with a plurality of partitions for steaming and baking different foods. The positioning structure 8 can also be provided with a plurality of corresponding ones, and is arranged on the side plate 5 at intervals.

[0032] The side plate 5 is provided with a plurality of raised portions 11 toward the inner cavity of the inner container, and grooves are formed between the plurality of raised portions, serving as positioning structures 8. The side plate 5 and the raised portions 11 can be processed as a whole, saving time and improving efficiency.

[0033] The side panels 5 are provided with connection holes 13 for installation and connection at the four corners. Preferably, the side panels 5 are quadrilaterals, and a connection hole 13 is provided at each of the four corners.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
