This application may, however, be embodied in many different forms and should not be construed as limited to the specific embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

FIG. 1 illustrates a partial top view schematic diagram of a cover assembly of an embodiment of the present application. Fig. 2 shows a schematic cross-sectional view in the direction a-a in fig. 1. Fig. 3 shows a schematic cross-sectional view in the direction B-B in fig. 1. As shown in fig. 1 to 3, a cover assembly 10 according to a first embodiment of the present application includes a cover 240, a portion of the cover 240 encloses to form a receiving cavity; a heating element 110 disposed in the accommodating chamber; and the fan 120 is arranged in the accommodating cavity and is positioned above the heating element 110, and the air outlet side of the fan 120 faces the heating element 110. The cover assembly 10 further includes a lifting device 130 connected to the fan 120 for driving the fan 120 to move up and down.

The cover assembly 10 provided in the embodiment of the present invention includes a cover 240, a heating element 110 disposed in the cover 240, a fan 120, and a lifting device 130, wherein the fan 120 can transfer heat generated by the heating element 110 to food materials. Since the fan 120 is internally integrated with electronic components requiring temperature rise, the excessive temperature may cause damage to the electronic components or cause the fan 120 to perform a self-protection function and stop working. In addition, the outer frame of some fans 120 is weak to high temperature and is easily burned. Therefore, the elevating device 130 is connected to the fan 120, and drives the fan 120 to move up and down to be away from or close to the heat generating element 110. When the temperature of the heating element 110 is high, the fan 120 is controlled to move upwards to be far away from the heating element 110, so that the damage of the fan 120 due to overhigh temperature rise is effectively avoided, the service life of the fan 120 such as electronic elements, an outer frame and the like is ensured, and the fan 120 is prevented from being stopped by mistake; also, when the temperature of the heating element 110 is low, the fan 120 is controlled to move down to be close to the heating element, so that certain heat is transmitted to the food material, the temperature in the cooking cavity where the food material is located is stable, and the heating efficiency is improved. Moreover, it is advantageous to continuously generate heat for a long time by the heat generating element 110 while ensuring the blowing effect and the service life of the fan 120.

In some embodiments, the lifting device 130 comprises a memory alloy member.

In these embodiments, the memory alloy member is made to drive the fan 120 up and down. On one hand, the structure is simple, the cost is low, the high temperature resistance is realized, the electric drive is not needed, and the energy is saved. On the other hand, since the memory alloy member can be extended when the temperature reaches the set value and retracted when the temperature is lower than the set value, the temperature around the heating element 110 can be accurately sensed, and the movement of the fan 120 can be accurately controlled, thereby effectively preventing the fan 120 from being damaged by baking.

Further, as shown in fig. 2 and 3, the lifting device 130 is disposed below the fan 120 to support the fan 120. The fan 120 can be pushed by the lifting device 130 to move up, and the fan 120 can be moved down by its own weight or the pulling force of the lifting device 130. Moreover, in the case that the lifting device 130 is made of a memory alloy, the lifting device 130 is closer to the heating element 110 than the fan 120, which is beneficial for the lifting device 130 to sense the temperature around the heating element 110 timely and accurately, thereby controlling the movement of the fan 120 accordingly and accurately.

Further, the memory alloy member is configured to elongate when the temperature is greater than or equal to the first set temperature to push the fan 120 away from the heat generating element 110, and is further configured to shorten when the temperature is less than the first set temperature to push the fan 120 close to the heat generating element 110. The first set temperature can be determined according to the heat-resistant temperature of the fan 120, so that the memory alloy member can push the fan 120 away from the heating element 110 in time when the temperature of the memory alloy member reaches the first set temperature.

Fig. 4 illustrates a partial exploded view of a cover assembly of one embodiment of the present application. In some embodiments, as shown in fig. 4, the lifting device 130 is a memory spring. The fan 120 can be stably supported and can be extended and shortened along a set direction, so that the fan 120 can be stably driven to move.

In a specific embodiment, as shown in fig. 6 and 7, the mounting platform 141 is not located at the bottom of the fan fixing frame 140, but the mounting platform can divide the inner cavity of the fan fixing frame 140 into a fan fixing cavity 142 and an air guiding cavity 143 which are distributed vertically and are communicated with each other, so that the fan 120 can be spaced from the heating element 110, and the damage to the peripheral frame and the like caused by the excessive approach of the fan 120 to the heating element 110 is avoided.

Further, as shown in fig. 6 and 7, the air guiding cavity 143 is flared, so that the air blown by the fan 120 is blown to the heating element 110 quickly and smoothly, and the heating effect is ensured.
