[0037] AsFigure 1 and Figure 2 As shown in

[0038] As shown in Figure 1 and Figure 2 Each support rod 122 is connected to the inner container 110 and located in the cooking cavity 111, in combination with Figure 3 The support rod 122 is telescopically arranged, as shown in Figure 2 When each support rod 122 is extended, it is erected between the first side wall 112 and the second side wall 113 to serve as a support, facilitating the support of the food materials placed on the placing rack assembly 120. In the present embodiment, the support rods 122 are arranged in parallel to facilitate the erection of the inner rib 121 on the support rods 122.

[0039] As shown in Figure 2 The inner rib 121 is detachably erected between adjacent support rods 122. When the placing rack assembly 120 does not need to place food materials, the inner rib 121 can be detached from the support rods 122 and stored separately. Then the support rods 122 are shortened to reduce the space occupied by the placing rack assembly 120, avoiding the separation of the space of the cooking cavity 111 by the erection of the placing rack assembly 120 between the first side wall 112 and the second side wall 113, thereby avoiding the problem of the top space of the cooking cavity 111 being unable to be utilized due to the obstruction of the placing rack assembly 120. Thus, when the placing rack assembly 120 is not used, the cooking equipment 100 can be utilized as completely as possible to adapt to the cooking requirements of large-volume food materials.

[0040] In the present embodiment, the support rod 122 is made of high-strength and high-temperature-resistant material, ensuring that it can maintain good function in a high-temperature environment without deformation or loosening, avoiding structural loosening or deformation caused by heavy load or operation.

[0041] In combination with Figure 4 and Figure 5As shown in the drawings, in one of the embodiments, the support rod 122 comprises a rotatingly connected telescopic part 1221 and a fixed part 1222, wherein the telescopic part 1221 is telescopically arranged, the fixed part 1222 is connected to the first side wall 112 or the second side wall 113, and the telescopic part 1221 can rotate relative to the fixed part 1222 to be parallel to the first side wall 112 or the second side wall 113 connected with the fixed part 1222. In this way, the telescopic part 1221 after being shortened can be parallel to the first side wall 112 or the second side wall 113, so as to further reduce the separation of the cooking space by the support rod 122, and further improve the utilization rate of the space in the cooking cavity 111.

[0042] As shown in the drawings, Figure 1 and Figure 2 In the present embodiment, one of the fixed parts 1222 of the support rod 122 is connected to the first side wall 112, and the telescopic part 1221 of the support rod 122 abuts against the second side wall 113 after being extended, so as to realize that the support rod 122 is erected between the first side wall 112 and the second side wall 113, and the telescopic part 1221 is parallel to the first side wall 112 after rotating relative to the fixed part 1222. The other fixed part 1222 of the support rod 122 is connected to the second side wall 113, and the telescopic part 1221 of the support rod 122 abuts against the first side wall 112 after being extended, so as to realize that the support rod 122 is erected between the first side wall 112 and the second side wall 113, and the telescopic part 1221 is parallel to the second side wall 113 after rotating relative to the fixed part 1222.

[0043] As shown in the drawings, Figure 4 and Figure 5 In one of the embodiments, the first side wall 112 or the second side wall 113 connected with the fixed part 1222 is concavely provided with a receiving groove 114. In the present embodiment, the first side wall 112 and the second side wall 113 are respectively provided with the receiving grooves 114 corresponding to the two support rods 122.

[0044] As shown in the drawings, Figure 5 and Figure 8 The receiving groove 114 comprises a first groove part 1141 for placing the fixed part 1222 and a second groove part 1142 for placing the telescopic part 1221, wherein the length of the second groove part 1142 is not less than the length of the telescopic part 1221 after being shortened, so that the telescopic part 1221 after being shortened can be received in the second groove part 1142, and when the support rod 122 is not used, the telescopic part 1221 after rotating relative to the fixed part 1222 is received in the receiving groove 114, so as to further reduce the influence of the support rod 122 in the non-use state on the space in the cooking cavity 111.

[0045] As shown in the drawings, Figure 1As shown, in one embodiment, the cooking device 100 comprises a driving source 130, the support rod 122 is connected to the driving source 130, and the driving source 130 is used to drive the telescopic part 1221 to telescope and rotate, so as to realize that when the support rod 122 is not needed, the driving source 130 automatically mobilizes the telescopic part 1221 to telescope and rotate, thereby improving the automation degree of the cooking device 100.

[0046] When the user finishes cooking, the placing rack assembly 120 can be folded and stored in the internal space of the cooking cavity 111. Since the volume of the placing rack assembly 120 after being folded is significantly reduced, the storage space is greatly saved, and the problem of occupying too much space when the traditional steaming and baking rack is not used is solved, which is especially suitable for the limited storage space of a family kitchen.

[0047] Generally, different cooking processes are usually adopted for different food materials, and the cooking device 100 can meet the cooking needs of various food materials by adjusting the position between the food material and the heating part used for heating, i.e., the food material is placed on the placing rack assembly 120 at different heights in the cooking cavity 111.

[0048] As shown in Figure 4 and Figure 5 As shown, in one embodiment, the support rod 122 is connected to the first side wall 112 or the second side wall 113, and the first side wall 112 or the second side wall 113 used for connecting the support rod 122 is provided with a vertically arranged moving track 115, and the support rod 122 is slidably arranged along the moving track 115, so that the support rod 122 can move vertically, thereby adjusting the height of the support rod 122, realizing the use of different heights of the placing rack assembly 120 in different cooking requirements, and enabling the user to adjust the height of the placing rack assembly 120 according to the needs of different food materials, thereby further improving the multifunctionality and operation flexibility of the cooking device 100. In this embodiment, the first side wall 112 and the second side wall 113 are respectively provided with the moving track 115 corresponding to the two support rods 122, and each support rod 122 is slidably connected to the corresponding moving track 115.

[0049] As shown in Figure 4 In one embodiment, the first side wall 112 or the second side wall 113 used for connecting the support rod 122 is also provided with a plurality of fixed grooves 116 in communication with the moving track 115, each moving track 115 is provided with a plurality of corresponding fixed grooves 116 on the side thereof, each fixed groove 116 is located on one side of the corresponding moving track 115, and the support rod 122 can slide from the moving track 115 into any fixed groove 116, thereby realizing that the support rod 122 is fixed in the fixed groove 116 at different heights. In other embodiments, the support rod 122 can also directly utilize the friction between the first side wall 112 and the second side wall 113 to realize the support.

[0050] As shown in Figure 4 In one embodiment, the fixing groove 116 is formed in one of the first side wall 112 and the second side wall 113, and the abutting groove 117 is formed in the other of the first side wall 112 and the second side wall 113. In this embodiment, the fixing groove 116 is formed in the first side wall 112, and the abutting groove 117 is formed in the second side wall 113. In addition, the fixing groove 116 is formed in the second side wall 113, and the abutting groove 117 is formed in the first side wall 112.

[0051] As shown in Figure 4 When the support rod 122 is extended, the two ends of the support rod 122 are inserted into the fixing groove 116 and the abutting groove 117, respectively, so as to be arranged between the first side wall 112 and the second side wall 113, thereby improving the support strength and reliability of the support rod 122. In this embodiment, as shown in Figure 6 The end of the telescopic rod inserted into the abutting groove 117 is an abutting block 1225, which corresponds to the structure of the abutting groove 117. In this embodiment, the bottom surface of the abutting block 1225 is a flat surface, so as to improve the support stability of the support rod 122.

[0052] In this embodiment, as shown in Figure 4 The number of the fixing grooves 116 is five, and correspondingly, the support rod 122 can be adjusted to five different heights in the cooking cavity 111, so as to adapt to the requirements of different food materials, for example, the food materials placed on the first layer are cooked by using the steaming function, the food materials placed on the second layer are cooked by using the ring air baking and full-open baking, and the food materials placed on the fifth layer are cooked by using the baking.

[0053] In one embodiment, the driving source 130 drives the support rod 122 to move along the moving track 115 and the fixing groove 116, so as to realize the automatic lifting of the support rod 122 driven by the driving source 130, thereby meeting different cooking requirements. In this embodiment, the driving source 130 is a stepping motor, but is not limited thereto.

[0054] As shown in Figure 5 In one embodiment, the first groove part 1141 of the receiving groove 114 is in communication with the moving track 115, and the receiving groove 114 is located at one end of the moving track 115. The support rod 122 can be directly moved into the first groove part 1141 along the moving track 115. When the driving source 130 drives the support rod 122 to move along the moving track 115, the fixed part 1222 of the support rod 122 can be directly moved to the first groove part 1141. At this time, the telescopic part 1221 is shortened and rotated to be received in the second groove part 1142, thereby realizing the automatic contraction and receiving of the support rod 122 driven by the driving source 130.

[0055] When the two support rods 122 are controlled by different or same driving sources 130, and when the fixed slots 116 corresponding to the two moving tracks 115 are located at the same side of the corresponding moving track 115, for example, the fixed slots 116 of the first side wall 112 and the second side wall 113 are both located at the side close to (or away from) the opening of the cooking cavity 111 of the corresponding moving track 115, the two support rods 122 can be adjusted in height synchronously without disassembling the inner frame 121.

[0056] In one of the embodiments, the cooking device 100 further comprises sensors for sensing the temperature, humidity and state of the food materials in the cooking cavity 111, and the driving sources 130 are controlled by the sensors, so that the driving sources 130 can automatically drive the support rods 122 to different heights under different states of the temperature, humidity and food materials in the cooking cavity 111, realizing that the user does not need to manually intervene, and the system can adjust the height of the shelf assembly 120 in real time according to the state of the food materials under heating. For example, when cooking pizza, it often needs to go through two stages of fermentation and baking. In the fermentation stage, the shelf assembly 120 is moved to the 3rd layer, and low-temperature fermentation is performed using thermal convection, so that the cooking cavity 111 is maintained at 38°C, so that the entire part of the pizza dough achieves the best fermentation effect. In the baking stage, the shelf assembly 120 is moved to the 5th layer, and relies on the top heating pipe for baking, so that the pizza reaches the mature temperature faster, shortens the cooking time, and realizes automatic cooking through program control.

[0057] As shown in Figure 6 In one of the embodiments, the inner frame 121 is foldable or rollable to facilitate storage and avoid occupying and dividing the space in the cooking cavity 111. Figure 6 As shown in

[0058] As shown in Figure 6 In one of the embodiments, the inner frame 121 comprises a connecting rod 1211 and a connecting wire 1212 connected to each other, a plurality of connecting rods 1211 are arranged in parallel and at intervals, and the connecting wire 1212 connects adjacent connecting rods 1211.
