Detailed Description

The utility model is further illustrated below with reference to examples.

In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of description of the present utility model and for simplification of the description, and are not to be construed as limiting the present utility model.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature.

Referring to fig. 1, 2, 3, a fan structure 4 for a steam box, oven or steam box comprises a second fan 5, a fan 6, a fan base 7, a heating pipe 8, a first fan 9, a nut 10.

The fan 6 comprises a stator and a rotor which are matched with each other, and the rotor is positioned on the outer side of the liner and connected with the second fan 5 for heat dissipation. The cooling fan is arranged outside the liner and is close to the shell, so that the temperature of the shell can be reduced, and the shell can be cooled more quickly. A mounting groove for placing a fan rotor is arranged above the fan base 8, and the lower end of the fan rotor 6 is sealed and placed into the liner. The fan base 8 isolates the heating system from the electronic components, so that heat dissipation in the box is reduced, enough heat in the box is guaranteed, and loss caused by excessive heat transferred to the electronic components is avoided to a certain extent. The first fan 9 is mounted on the rotor of the fan 6 in the ring of the heating tube 8 and is finally fixed by means of a nut 11. The first fan 9, the second fan 5, the fan base 7 and the heating pipe 8 are connected on an axle center by nuts, and the fixation is firm. Preferably, one end of the second fan 5 close to the fan 6 is an air inlet, and the other end is an air outlet. One end of the first fan 9, which is close to the heating pipe 8, is an air outlet, the other end of the first fan is an air inlet, and the first fan 9 is mainly used for timely and circularly conveying heat on the heating pipe 8 to all parts inside the inner container.

Referring to fig. 1, the fan structure 4 of the present utility model may be applied to an electric appliance requiring high-temperature uniform heating, such as an oven, a steam box, a steaming and baking all-in-one machine, etc. In this embodiment, the fan structure 4 is used in a steaming oven, fig. 1 is a schematic diagram of the rear side of the steaming oven, the left side in the diagram is the steaming oven body 1, the right side in the diagram is the oven body 2, the front end is the control panel 3, and a mounting groove is arranged above the oven body 2 for placing the fan structure 4, but the stator and the rotor of the fan are open, which is more beneficial to heat dissipation. After the oven is powered on, as the rotor of the fan 6 is simultaneously connected with the first fan 9 and the second fan 5, the two fans can simultaneously rotate without additionally arranging a driver, and the heat dissipation system is started to timely dissipate heat for the fan while generating heat. The first fan 9 rotates below the heating pipe to drive the hot air in the box body to circulate and even the temperature in the box body. At this time, because the fan 6 is installed close to the inner container, the heat in the inner container can be partially transferred to the coil of the fan 6 and other electronic components, and the heat of the self heat superposition heating tube is easy to lose the coil of the fan or/and other electronic components, so that the fan failure rate is high. The second fan 5 rotates above the fan 6 to timely dissipate heat of the coil and the electronic components, so that loss is reduced.

The mounting position of the fan structure 4 may be adjusted according to actual needs, and may be mounted sideways or below. If the box body is relatively large, one box body can be arranged at the upper part and the lower part. Preferably, the shell of the box body is made of metal materials with heat dissipation holes.

The foregoing description is only of the optional embodiments of the present utility model, and is not intended to limit the scope of the utility model, and all the equivalent structural changes made by the description of the present utility model and the accompanying drawings or the direct/indirect application in other related technical fields are included in the scope of the utility model.
