[0034] The steaming cabinet is a relatively conventional processing equipment, which is generally used for processing food and Chinese herbal medicines, etc. The steaming cabinet heats water through the built-in heating element to generate high-temperature steam. These steam circulates in the closed cabinet body to uniformly heat the food. The steaming cabinet usually has good sealing performance in order to maintain the temperature and humidity during the steaming process. This means that the water vapor is effectively enclosed in the cabinet body during the steaming process. When the cabinet door is opened, these accumulated water vapor will quickly rush out;

[0035] In order to avoid burns, it is generally necessary to open the cabinet door first and wait for the water vapor inside to dissipate before taking out the food inside. However, after the accumulated water vapor dissipates, the water vapor in the steam generator below and the lower cavity will still continue to rise. Therefore, after most of the accumulated water vapor dissipates, the subsequent water vapor that continues to rise will still affect the workers.

[0036] like Figures 1-9 As shown, the present application proposes a steaming cabinet, which is provided with a multi-layer heating structure. When the food in one layer needs to be taken out, the corresponding cabinet door can be opened. After opening, the barrier component 8 at the lower part of the space of this layer will be closed to prevent the water vapor in the lower space from rising upward. After the water vapor in the space of this layer dissipates, the food can be taken out. On the one hand, since the space of this layer will be separated to form an independent space after the cabinet door is opened, a large amount of water vapor loss inside is avoided, and the heat utilization efficiency is improved. On the other hand, it is only necessary to wait for the water vapor in the independent space to dissipate, and there will be no subsequent water vapor rising to the steaming space and then escaping. Therefore, the waiting time can be reduced, the efficiency of taking food or medicinal materials can be improved, and the steaming efficiency can be improved.

[0037] A cooking cabinet comprises a cabinet structure 1, a steam generation and control system is installed at the lower part of the cabinet structure 1, a heating chamber is formed at the upper part of the cabinet structure 1, water vapor is generated by the steam generation and control system, and the water vapor enters the heating chamber along the channel to heat the food or medicinal materials, a multi-layer cooking plate assembly is vertically arranged in the heating chamber, and the multi-layer cooking plate assembly can be heated simultaneously during the upward rising process of water vapor, and a barrier assembly 8 is provided at the lower part of each cooking plate assembly, and the barrier assembly 8 divides the heating chamber into multiple layers of cooking space in the vertical direction, and each layer of cooking space is provided with a sealed cabinet door 4, and different food or medicinal materials can be heated at the same time through the layered arrangement, or different batches of food and medicinal materials can be heated, and can be taken in and out separately, thereby preventing a large amount of water vapor from escaping during the taking in and out process of a single cabinet door. In this case, when the sealed cabinet door 4 is closed, the barrier component 8 forms a connecting opening for water vapor to pass through. When the sealed cabinet door 4 is opened, the barrier component 8 forms a plate to separate the cooking space from the lower space. Therefore, when the sealed cabinet door 4 is closed, the water vapor generated by the steam generation and control system can flow from bottom to top without hindrance, so that multiple layers of food and medicinal materials can be heated simultaneously. When the sealed cabinet door 4 is opened, the barrier component 8 of this layer will be turned into a plate. The water vapor at the bottom is blocked by the plate and cannot or can only rise in a small amount, cutting off the channel for water vapor to flow into this layer, so that food and medicinal materials can be easily taken and placed. On the one hand, the amount of water vapor escaping when the sealed cabinet door 4 is opened is reduced. On the other hand, the water vapor loss efficiency is improved. After the loss, no new water vapor will continue to be replenished, thereby improving the efficiency of taking and placing food and medicinal materials.

[0043] Further, the frame body includes detachable upper frame body 801 and lower frame body 802, and when the upper frame body 801 and the lower frame body 802 are combined into a whole, circular through holes and rectangular through holes are formed at both sides, the rotating shaft 803 is rotatably arranged at the two ends of the circular through holes, and the rack 806 is arranged at the two ends of the rectangular through holes.

[0044] Specifically, the upper frame body 801 and the lower frame body 802 are made of high-temperature-resistant hard plastic, and the joint surfaces of the two are respectively provided with clamping grooves and clamping teeth, so that they can be detachably connected, or other convenient connection methods can be used, such as one side of the rotating connection and the other side of the locking connection, arc-shaped through grooves 809 are formed on the lower sides of the left and right side rods of the upper frame body 801, and arc-shaped through grooves 809 are formed on the upper sides of the left and right side rods of the lower frame body 802, so that when the upper and lower frame bodies 802 are combined, a structure is formed for the rotating shaft 803 to rotate and avoid the rotating shaft 803 to move left and right, and similarly, U-shaped grooves 810 are formed at the two ends of the front and rear side rods of the lower frame body 802, and bosses 811 are formed at the two ends of the front and rear side rods of the upper frame body 801, so that the bosses 811 extend into the U-shaped grooves 810 to form a sliding channel matched with the rack 806, which can limit the rack 806 and provide a reciprocating movement path, and also facilitate the disassembly and assembly of the rack 806.

[0045] Further, limit blocks 808 are formed at the two ends of the rack 806, the reset spring 805 is fixedly connected with one of the limit blocks 808, and the size of the limit block 808 is greater than the size of the rectangular through hole.
