Description

Technical Field

[0001] This utility model relates to the technical field of double-head steam ovens, specifically an environmentally friendly and energy-saving double-head steam oven. Background Technology

[0002] Currently, double-head steamers are mainly used in food processing in the catering industry. They are frequently used in restaurants, canteens, and street-side fast food outlets to process food. Double-head steamers have many advantages, such as high efficiency, energy saving, environmental protection, and safety.

[0003] In existing technologies, similar to the aforementioned double-headed steamers, during food processing, a water tank inside the steamer is heated to boiling and evaporate the water. Food is placed on the steamer surface above the water tank for heating. However, after the food is cooked and removed, the water tank still emits a significant amount of residual heat. The water temperature remains close to boiling, continuing to radiate heat. This heat dissipates gradually, or the water is drained, leading to heat loss. Subsequent food processing requires reheating the water, increasing energy consumption. Therefore, those skilled in the art have proposed an environmentally friendly and energy-saving double-headed steamer to address the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide an environmentally friendly and energy-saving double-head steam oven to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An environmentally friendly and energy-saving double-head steam oven includes a furnace body with supporting legs connected to the bottom. Two water tanks are symmetrically installed on the top of the furnace body. A positioning frame is set at the top of the furnace body and directly above the water tanks. Inlet and outlet pipes are connected to the sides of the water tanks, with one end of each pipe extending outside the furnace body. A heater is installed at the bottom of the inner cavity of each water tank. A gathering hood is set in the middle of the inner cavity of each water tank, and a diffusion hood is set at the top of the inner cavity. The top of the gathering hood is connected to the bottom of a connecting pipe, and the bottom of the diffusion hood is connected to the top of the connecting pipe. A switch assembly is installed on the connecting pipe. A control box is installed inside the furnace body, and an operation panel is installed at the top of the furnace body. The heater, the switch assembly, and the operation panel are all connected to the control box via wiring.

[0007] As a further embodiment of this utility model: the switch assembly includes a closed disc and a rotating rod. The closed disc is disposed in the middle of the inner cavity of the connecting pipe. The outer diameter of the closed disc is the same as the inner diameter of the connecting pipe. A driving component is installed on the outer wall of the water tank. One end of the rotating rod extends into the connecting pipe and is connected to the outer wall of the closed disc. The other end of the rotating rod is connected to the output end of the driving component.

[0008] As a further embodiment of this utility model: the bottom end of the diffusion cover is provided with a circular hole, and a polygonal partition is provided inside the diffusion cover, with the bottom end of the polygonal partition connected to the circular hole.

[0009] As a further embodiment of this utility model: the outer wall of the gathering cover slides and fits against the inner wall of the water tank, a tube is connected to the middle of the gathering cover, the top end of the tube is inserted and connected to the bottom end of the connecting tube, and a telescopic component is installed at the bottom end of the diffusion cover, the bottom end of the telescopic component is connected to the top of the gathering cover.

[0010] As a further improvement of this utility model, the outer wall of the water tank is equipped with a heat insulation layer.

[0011] This invention has the following advantages: Steam is drawn through a converging hood and passes through a connecting pipe. A switch assembly is used to open or close the connecting pipe. After the water tank finishes one operation, the heat in the water tank can be retained by closing the connecting pipe, which can greatly reduce the loss of steam and heat in the water tank. When the stacked steamers are heated again, the energy consumption of the heater is reduced. When the water tank is working, the steam in the connecting pipe is diffused through a diffuser hood. The diffuser hood is equipped with multi-sided baffles, which can evenly diffuse the steam, ensuring that the stacked steamers are heated evenly and have a better performance.
