The upper outer side of the water tank is provided with a water tank steam outlet, the lower outer side of the water tank is provided with a water tank water inlet, and the outer side of the water tank is also provided with a float switch. The present invention has the advantages of reasonable structure, convenient operation and good use effect.

[0004] However, this patent cannot reuse the heat of the oven to steam the food in the steamer while grilling, and cannot quickly take the steamed food out of the steamer. Moreover, when the fan-shaped bucket of the oven of this patent is folded, the chain inside the fan-shaped bucket will be loose and in a non-tightened state. When the fan-shaped bucket is opened again to expand outward, the chain needs to be manually supported to align the chain.

[0005] Patent application number: 2024107701326 discloses an outdoor multi-purpose energy-saving stove, which includes a box body and a stove body, wherein the stove body is detachably nested inside the box body, an inner cavity is arranged inside the box body on the other side relative to the stove body, an opening and closing grill is arranged on one side outside the box body, the opening and closing grill is movably connected to the box body and can move toward the inner cavity, and a folding storage plate is arranged on the other side outside the box body; a coil is detachably nested inside the stove body, and a detachable fixing frame is also arranged outside the coil to realize the forming support of the coil; when only grilling and heating food materials are needed, the stove body is placed in the box body, fuel is placed in the rectangular hole of the box body and ignited, and then an ash unloading hopper is placed in the rectangular hole to unfold the grill; when people finish heating and using food and heating is needed in the tent, the coil is installed inside the stove body; the present invention has the advantages of reasonable structure, effectively solving the problems of scale and dust, greatly improving heat utilization rate, improving structural rigidity, and extending service life.

[0006] This patent also does not have the function of using the heat of the grill to steam the food inside the steamer at the same time as the grilling. The heat of the grilling can only be used for grilling. And this patent also has the problem that the grilling chain becomes loose when the furnace body is folded. In addition, the coil of this patent is a single-layer coil structure, which requires two tubes to be used together to achieve water circulation. The newly developed double-layer tube structure of the present invention can achieve water circulation under the action of one tube, using less materials, reducing accessories and achieving better results.
