[0029] Embodiment one
[0030] The first embodiment of the single-evaporation-pan internal circulation system includes a box body 100 provided with a cooking cavity 110, an evaporation pan 200 arranged inside the box body 100, a condensation system 300 for condensing steam, a drainage system 400, and a water tank. The condensation system 300, the drainage system 400, and the water tank are connected with the box body 100. The drainage system 400 is used for draining the condensed water in the condensation system 300 to the inner wall of the cooking cavity 110. The condensation system 300 is in communication with the cooking cavity 110. The water tank is in communication with the evaporation pan 200.
[0031] As shown in Figure 1 , the single-evaporation-pan internal circulation system in this embodiment first adds water to the evaporation pan 200 through the water tank. The evaporation pan 200 starts heating work. The evaporated high-temperature steam enters the cooking cavity 110 to heat food. Part of the steam floats to the condensation system 300 and is converted into condensed water under the action of the condensation system 300. The drainage system 400 drains the condensed water to the inner wall of the cooking cavity 110. The condensed water flows down along the inner wall of the cooking cavity 110 and finally returns to the evaporation pan 200 for secondary evaporation. The condensed water is heated into steam again to participate in the heating process of the food in the cooking cavity 110. The single-evaporation-pan internal circulation system realizes the recycling of steam, reduces water consumption, and realizes the continuous work of the evaporator. At the same time, it reduces the amount of steam discharged from the steam cooking equipment, avoids the moisture of the wooden structure of the cabinet, and improves the steam content in the cooking process through the secondary evaporation of the steam converted into condensed water, realizing large-steam steaming and baking.
[0032] The evaporation pan 200 is arranged at the center of the bottom of the cooking cavity 110. The bottom of the cooking cavity 110 is inclined to the evaporation pan 200. Figure 2 As shown in , the bottom of the cooking cavity 110 is inclined to the evaporation pan 200 at the center, so that the condensed water on the side wall of the cooking cavity 110 converges to the evaporation pan 200 at the center of the bottom. On the one hand, the evaporation pan 200 cooperates with the condensation system 300 to realize the circulation of steam-condensed water-steam, reducing water consumption during work. On the other hand, it reduces the amount of residual condensed water in the cooking cavity 110, making it convenient for users to clean. When the user uses the box body 100 as an oven, the evaporation pan 200 at the bottom of the cooking cavity 110 can work synchronously when baking food in the cooking cavity 110, providing auxiliary heating effect, indirectly baking the food in the cooking cavity 110, and increasing the heating speed in the cooking cavity 110.

The condensate is evaporated together in the evaporation plate 200, increasing the amount of steam in the cooking chamber 110.
[0035] Both the first evaporation chamber 211 and the second evaporation chamber 212 are annular, with the radius of the first evaporation chamber 211 being smaller than the radius of the second evaporation chamber 212. For example... Figure 5 , Figure 6 As shown, both the first evaporation chamber 211 and the second evaporation chamber 212 are annular and have a concentric circle structure. The radius of the first evaporation chamber 211 is smaller than that of the second evaporation chamber 212. It is located at the center of the evaporation plate 200 and is connected to the water inlet 230 to receive pure water from the water tank for evaporation. The radius of the second evaporation chamber 212 is larger and is located around the evaporation plate 200. It is used to receive condensate from the condensation system 300 for evaporation.
[0036] like Figure 6 As shown, the evaporation pan 200 in this embodiment has a recessed cavity 240, which is connected to the water inlet 230 and the first evaporation chamber 211. Water from the water tank enters the evaporation pan 200 through the water inlet 230, and first reaches the recessed cavity 240 for buffering to prevent the water flow from overflowing from the evaporation pan 200 due to excessive speed, while also preventing scale and other debris from clogging the water inlet 230, making it easier to clean. Subsequently, the water flows to fill the first evaporation chamber 211, which is connected to the recessed cavity 240, and gradually evaporates into steam, participating in the food cooking process.
