Therefore, a heat circulation space for circulating hot air is formed between the working surfaces of the pot body 10 and the upper reflection plate 42.

The temperature of the base 30 can be raised by the hot air circulation, in order to realize the heat dissipation of the base 30, the base 30 in this embodiment includes an outer wall 31 and an inner wall 32, and a hollow structure is formed between the outer wall 31 and the inner wall 32 of the base 30, a third air inlet 30A is opened on the upper end surface of the base 30 corresponding to the second air vent 47C, and a third air vent 30B communicated with the third air inlet 30A is opened on the outer wall 31 of the base 30 (when the pot cover 40 is covered on the base 30, the lower end surface of the support ring 472 on the motor frame 47 is in contact fit with the upper end surface of the base 30); a cold circulation space for cold air circulation is formed among the shell 41, the upper end surface of the upper reflecting plate 42, the motor frame 47 and the base 30; in this embodiment, the third ventilation opening 30B is disposed at the bottom and the rear side of the base 30, a part of the cool air flows out from the bottom of the base 30 to enter the outside, another part of the cool air flows out from the rear side of the base 30, and the cool air flowing out from the rear side of the base 30 can further cool the rotating plate 53.

Therefore, the cooling air circulation path in this embodiment is: after the outside air is sucked into the motor frame 47 along the first air inlet 41A of the housing 41 and the second air inlet 47A of the motor frame 47, the outside air is blown out from the first ventilation opening 47B under the action of the cold air blade 43, and a part of cold air blown out from the first ventilation opening 47B enters the rotating plate 53 from the fourth air inlet 53A, flows out from the fourth ventilation opening 53B after cooling the circuit board in the rotating plate 53, and is blown to the outside; another part of the cool air is blown out from the second ventilation opening 47C of the motor frame 47 and enters the inside of the base 30 from the third ventilation opening 30A of the base 30 to cool the base 30, prevent the base from overheating, and then goes out from the third ventilation opening 30B.

When the cooker is used, in order to avoid the situation that cooking is carried out without placing the cooker body 10, a microswitch 60 for detecting whether the cooker body 10 is placed or not and a transmission piece 61 capable of triggering the microswitch 60 are further arranged. As shown in fig. 18, 19 and 20, the micro switch 60 is a normally open structure, the air fryer only works when the micro switch 60 is open, the pan body 10 is provided with a trigger part which is matched with the transmission member 61, the trigger part acts on the transmission member 61 when the pan body 10 is positioned in the machine base to enable the micro switch 60 to be still in the open state, and the transmission member 61 resets and drives the micro switch 60 to be closed when the pan body 10 is separated from the machine base. Since the base of the embodiment includes the base 30 and the lid 40, in order to detect whether the lid 40 is closed or not, the micro switch 60 and the transmission member 61 are disposed on the lid 40 (in this embodiment, the micro switch 60 and the transmission member 61 are disposed on the motor frame 47), the trigger portion acts on the transmission member 61 to make the micro switch 60 still in the open state when the lid 40 is closed and the pot body 10 is located in the base 30, and the transmission member 61 resets and drives the micro switch 60 to close when the lid 40 is opened or/and the pot body 10 is away from the base 30. In order to ensure that the pot body 10 can be stably matched with the transmission piece 61, the upper edge of the pot body 10 is provided with a flanging 11, and the trigger part is positioned on the flanging 11 so as to increase the contact surface of the pot body 10.

The specific structure of the transmission member 61 is: the transmission member 61 comprises a transmission rod 62 vertically arranged and a spring 63 sleeved on the transmission rod 62 to enable the transmission rod to always have a downward moving trend, the lower end of the transmission rod 62 is matched with the trigger part to be separated from or act on the trigger part, and the upper end of the transmission rod 62 is matched with a contact 64 of the microswitch 60 to be closed or separated from the contact 64; in a state where the lower end of the transmission lever 62 acts on the trigger portion, the transmission lever 62 moves upward, and the upper end of the transmission lever 62 is disengaged from the contact 64 of the microswitch 60; when the lower end of the transmission rod 62 is separated from the trigger portion, the transmission rod 62 moves downward and returns by the spring 63, and the upper end of the transmission rod 62 contacts with the contact 64 of the microswitch 60 to drive the contact 64 to close. (in this embodiment, the upper end of the transmission rod 62 is protruded with a step 621, the step 621 is located above the contact 64 of the micro switch 60, when the transmission rod 62 moves downwards, the step 621 contacts with the contact 64 of the micro switch 60 and drives the contact 64 to be closed, and when the transmission rod 62 moves upwards, the step 621 is separated from the contact 64 of the micro switch 60, and the contact 64 is in an open state). In order to make the transmission rod 62 work stably, the transmission member 61 further comprises a support seat 65 disposed on the motor frame 47 of the pot cover 40, a guide groove 650 is vertically disposed on a side surface of the support seat 65, and the transmission rod 62 is disposed in the guide groove 650 and can move up and down along the guide groove 650; the microswitch 60 is disposed at the upper portion of the support base 65. In order to limit the moving distance of the transmission rod 62, a first step 651 for limiting the highest position of the transmission rod 62 is provided at the upper portion of the guide groove 650, a second step 652 for limiting the lowest position of the transmission rod 62 is provided at the lower portion, and a flange 622 for engaging with the first and second steps is provided on the transmission rod 42. The spring 63 is sleeved on the transmission rod 62 and then positioned in the guide groove 650, the lower end of the spring 63 is supported on the flange 622, the upper end of the spring 63 can abut against the first step 651, and the spring 63 is compressed in the upward movement process of the transmission rod 62, so that the transmission rod 62 always has a downward movement tendency. Thus, when the lower end of the transmission rod 62 is separated from the trigger portion (i.e. the pot body 10 is not put into the base 30 or/and the pot cover 40 is not covered), the transmission rod 62 moves downwards under the action of the spring 63, the upper end of the transmission rod 62 drives the micro switch 60 to be closed, and when the micro switch 60 is closed, the air fryer cannot perform cooking work. When the lower end of the transmission rod 62 abuts against the trigger part (i.e. the pot body 10 is put into the base 30 and the pot cover 40 is covered), the transmission rod 62 moves upwards, the upper end of the transmission rod 62 is far away from the micro switch 60, the micro switch 60 is in a normally open state, and the air fryer can perform cooking.

In order to prevent the lid 40 from being stuck or untight during the closing process, the closing surface of the lid 40 and the base 30 is an inclined surface with an inclination B of less than or equal to 30 degrees, which is inclined toward the rear and lower side, as shown in fig. 17. And because the driving motor 45, the heating element 46, the hot air fan 44 and other parts are all arranged in the pot cover 40, the pot cover 40 is heavier, and in order to avoid accidental hand clamping when the pot cover 40 is opened, a torsional spring is arranged at the rotary joint of the pot cover 40 and the base 30, namely, the torsional spring is arranged on the rotating shaft 54 of the rotating mechanism 50, so that the pot cover 40 can be slowly opened under the action of the torsional spring after being opened. As shown in fig. 16 and 18, in order to detect the temperature in the pan, a temperature detecting device 70 is further disposed on the pan cover 40, and the temperature detecting device 70 can refer to the prior art and is not described herein.
