Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen utensils, in particular to a cooking device with a baking function. BACKGROUND

[0002] In the process of the cooking device such as an oven, a steam oven and a steam oven integrated with a stove executing the baking function, the hot air blower makes the hot air uniformly distributed in the inner container through forced convection, so as to ensure that the food can be uniformly heated in the heating process, so as to obtain an ideal baking effect and prevent the food from being locally roasted or locally uncooked. Therefore, the stable operation of the hot air blower plays an important role in obtaining an ideal baking effect.

[0003] The hot air blower is usually installed at the back side of the inner container. In the process of the cooking device executing the baking function, the temperature of the inner container is very high, which makes the temperature rise of the hot air blower and the driving motor in the hot air blower higher, which seriously affects the service life of the hot air blower. In the traditional technology, the way to solve the higher temperature rise of the driving motor is as follows: a larger rear positioning plate is installed outside the back side of the inner container, the seat body of the driving motor in the hot air blower is installed on the rear positioning plate, and the larger rear positioning plate is used to absorb heat to reduce the temperature rise of the driving motor. However, in order to ensure that the rear positioning plate can absorb enough heat, the rear positioning plate must be made very large, so that the weight of the cooking device is significantly increased, which brings inconvenience to the installation and maintenance of the cooking device.

[0049] Referring to Figures 1 to 9 The present application provides a cooking device with baking function, which comprises an inner container 1, a heating pipe 2, a rear positioning plate 3, a hot air machine 5 and a blower 6. The heating pipe 2 is fixedly arranged in the inner container 1 and opposite to the back side of the inner container 1.

This effect is achieved by forced convection, rather than using the heat absorption of the rear positioning plate 3. Therefore, the rear positioning plate 3 can be made smaller in size, which can reduce the weight of the cooking device. In addition, the arrangement of the air inlet 31 and the air outlet 32 can also reduce the weight of the cooking device. These two factors can significantly reduce the weight of the cooking device, thereby facilitating the installation and maintenance of the cooking device.

This allows the cold air flowing into the air chamber 4 from the outside to flow to the vicinity of the seat body 511 from multiple positions, which is conducive to uniformly cooling the seat body 511, reducing the temperature rise of the driving motor 51, and improving the service life of the hot air machine 5.

[0054] Referring to Figure 5 and Figure 6 , at least part of the air outlets 32 are arranged opposite to the seat body 511. This is conducive to cooling the seat body 511, reducing the temperature rise of the driving motor 51, and improving the service life of the hot air machine 5.

[0055] Referring to Figure 5 and Figure 6 , the air outlet 32 is a cylindrical hole, and the axis of the air outlet 32 is parallel to the axis of the rotating shaft 512. This is conducive to cooling the seat body 511, reducing the temperature rise of the driving motor 51, and improving the service life of the hot air machine 5.

[0056] In some embodiments, the air outlet 32 can also be provided with only one, which is an arcuate shape and the center of which is located on the rotating shaft 512.

[0057] Referring to Figure 9 , the seat body 511 is provided with a plurality of heat dissipation holes 5111. This is conducive to cooling the seat body 511, reducing the temperature rise of the driving motor 51, and improving the service life of the hot air machine 5.

[0060] Referring to Figure 6The cooking device with the baking function further comprises a sealing member 7, which is arranged around the rotating shaft 512 and sealingly connected with the back side of the inner container 1, so as to separate the gap between the rotating shaft 512 and the back side of the inner container 1 from the air chamber 4. In other words, the air chamber 4 is annular, and is a ring-shaped closed space when the air inlet 31 and the air outlet 32 are both closed. In this way, the cold air flowing into the air chamber 4 from the outside all flows to the vicinity of the seat body 511 from the air outlet 32, which is beneficial to heat dissipation of the seat body 511, reduces the temperature rise of the driving motor 51, and improves the service life of the hot air machine 5.
