[0027] Such as Figures 1-4As shown in the figure, an energy-saving steamer includes a pot rack 1, a heat exchange pipe 2, and a water inlet pipe 3. A steam generator 4 and a steaming box 5 are respectively arranged on the pot rack 1. An air inlet 51 is opened at one end of the steaming box 5. The steam outlet end of the steam generator 4 is communicated with the air inlet 51. A water and steam discharge port 52 is opened at the bottom end of the steaming box 5. The heat exchange pipe 2 is arranged in the pot rack 1 and is located on one side of the steaming box 5. A water and steam receiving pipe 21 is connected to the side wall of the heat exchange pipe 2. The water and steam discharge port 52 is communicated with the water and steam receiving pipe 21. A drain port 22 is opened at the bottom end of the heat exchange pipe 2. The water inlet pipe 3 is bent and arranged in the heat exchange pipe 2. One end of the water inlet pipe 3 is communicated with an external water source, and the other end of the water inlet pipe 3 is communicated with the water inlet end of the steam generator 4. When in use, the steam generated by the steam generator 4 will flow through the steam outlet end, the pipeline, and the air inlet 51 in sequence, and then enter the steaming box 5 to heat the dishes. The condensed water generated by the steam and part of the waste steam can enter the heat exchange pipe 2 through the water and steam discharge port 52, the pipeline, and the water and steam receiving pipe 21 in sequence. The heat of the condensed water and part of the waste steam entering the heat exchange pipe 2 will be transferred to the clear water in the water inlet pipe 3 through the pipe wall of the water inlet pipe 3, so that the clear water transported by the water inlet pipe 3 to the steam generator 4 has a certain amount of heat, achieving the preheating effect, thereby effectively using the heat of the waste steam to save the energy consumption of the steam generator 4 and achieving the purpose of energy saving.
[0028] Further, an electric control valve 61 is arranged on the water and steam receiving pipe 21 to call the waste steam according to actual production needs and improve the utilization rate of the waste heat.
