[0025] Embodiments

[0026] As Figures 1-5 shown, a novel high-efficiency steam heating steamer furnace, including heat exchange steam box 1, heat exchange steam box 1 bottom is closed and has box bottom plate, heat exchange steam box 1 top is closed and has box top cover 2, the box inside of heat exchange steam box 1 is evaporation water cavity 11 (evaporation water cavity 11 is used to store the water for evaporation), the box bottom plate of heat exchange steam box 1 is opened and has box bottom plate flame inlet 31, the box bottom plate of heat exchange steam box 1 extends to evaporation water cavity 11 sealed and has the flame flue gas collection cylinder 3 that communicates with box bottom plate flame inlet 31, flame flue gas collection cylinder 3 and box bottom plate flame inlet 31 are sealed and integrated, flame flue gas collection cylinder 3 extends into the box inside of heat exchange steam box 1 certain height, flame flue gas collection cylinder 3 and heat exchange coil 6 are sealed and connected. The evaporation water cavity 11 of heat exchange steam box 1 forms a sealed and impermeable water water tank.

[0027] The bottom of the heat exchange steam box 1 is equipped with a combustion stove corresponding to the flame inlet 31 on the bottom plate. The combustion stove can be an existing gas stove (the fuel used by the gas stove is gaseous fuel, such as natural gas or liquefied petroleum gas), or it can be a combustion stove with a vaporizer, which vaporizes the liquid fuel into atomized vaporized gas. The heat exchange steam box 1 is equipped with a combustion switch 5 corresponding to the combustion stove. The combustion switch 5 is used to switch the ignition and combustion operation. When the combustion switch 5 is turned on, the fuel is ignited and burned. The combustion of the fuel by the combustion stove produces a flame and high-temperature flue gas. The center of the flame is directly opposite the flame inlet 31 on the bottom plate of the box. The bottom plate of the heat exchange steam box 1 covers the area around the flame and heats it. Part of the flame and high-temperature flue gas are collected in the flame and flue gas collecting cylinder 3 to form high-temperature flue gas. The heat exchange coil 6 is installed inside the evaporation water chamber 11. The heat exchange coil 6 is located inside the evaporation water chamber 11 and is surrounded by water in the evaporation water chamber 11. In this way, the high-temperature flue gas in the heat exchange coil 6 will have a full heat exchange with the water in the evaporation water chamber 11. The heat of the high-temperature flue gas is fully utilized before it is discharged through the external exhaust pipe.

[0028] The heat exchange coil 6 consists of several layers of coils, each layer being S-shaped. The inlet end of the heat exchange coil 6 is in a sealed connection with the flame and flue gas collecting cylinder 3. A flue gas adapter 4 is installed on the side wall of the heat exchange steam box 1, and the outlet end of the heat exchange coil 6 is in a sealed connection with the flue gas adapter 4. The flue gas adapter 4 is also in a sealed connection with an external exhaust pipe, which is used to discharge the flue gas after heat exchange. The S-shaped tubes of the heat exchange coil 6 are distributed in the evaporation water chamber 11. The space in the evaporation water chamber 11, excluding the heat exchange coil 6, is the space for water to be evaporated. The space for water to be evaporated is the storage space for water. The water used for evaporation in the heat exchange steam box 1 is stored in the space for water to be evaporated.

[0029] like Figure 4 , Figure 5 As shown, the heat exchange coil 6 consists of upper and lower coils and a flue gas integrated pipe 63. Both the upper and lower coils are composed of two S-shaped tubes. The two S-shaped tubes of the lower coil are connected to the flame and flue gas collecting cylinder 3, and the two S-shaped tubes of the upper coil are connected to the flue gas integrated pipe 63. The flue gas integrated pipe 63 has a flue gas outlet 631, which passes through the wall of the heat exchange steam box 1 and is sealed to the flue gas adapter 4. The specific structural scheme is as follows: the two S-shaped tubes of the lower coil are S-shaped tube A61 and S-shaped tube B62, which are arranged symmetrically from left to right; the two S-shaped tubes of the upper coil are S-shaped tube C and S-shaped tube D, which are arranged symmetrically from left to right; the S-shaped tube A61 of the lower coil and the S-shaped tube C of the upper coil form a single integrated pipe, and the S-shaped tube B62 of the lower coil and the S-shaped tube D of the upper coil form a single integrated pipe.

[0030] In some embodiments, the heat exchange steam box 1 is provided with a water supplement pipe and a drain pipe 8 communicating with the evaporation water cavity 11, and the water supplement pipe and the drain pipe 8 are arranged in an up-down manner (the water supplement pipe is arranged at a higher position than the drain pipe 8). As shown in Figure 3 , the heat exchange steam box 1 is provided with a water supplement pipe mounting hole 7 in the side wall for sealingly mounting the water supplement pipe (the water supplement pipe passes through the water supplement pipe mounting hole 7, and then the water supplement pipe mounting hole 7 is sealed to eliminate the gap of the water supplement pipe). The water supplement pipe is provided with a water supplement pump, and the drain pipe 8 is provided with a drain pump.

[0031] In some embodiments, the heat exchange steam box 1 is provided with a high-level sensor and a low-level sensor for detecting the water level in the evaporation water cavity 11 (as shown in Figure 3 , the high-level sensor is sealingly mounted at the high-level sensor mounting hole 9 in the side wall of the heat exchange steam box 1, and the low-level sensor is sealingly mounted at the low-level sensor mounting hole 10 in the side wall of the heat exchange steam box 1), and the high-level sensor and the low-level sensor are arranged in a high-low manner, and the high-level sensor is arranged at a lower position than the water supplement pipe. When the water level in the heat exchange steam box 1 is lower than the position of the low-level sensor, the low-level sensor detects that the water level is low and triggers the water supplement pump to start, and the water supplement pipe is used to supplement water into the heat exchange steam box 1. When the water level in the heat exchange steam box 1 is higher than the position of the high-level sensor, the high-level sensor detects that the water level is high and triggers the water supplement pump to stop.

[0032] The box top cover 2 is provided with a steam outlet 21 for releasing high-temperature steam, and the diameter of the steam outlet 21 is smaller than that of the steamed bun steamer and corresponds to the steamed bun steamer, so that the high-temperature steam can fully steam the steamed buns in the steamed bun steamer; as shown in Figure 1 , the edge of the box top cover 2 has an edge, and all the edges of the box top cover 2 form a steamed bun box recessed cavity (the steam outlet 21 is located at the center of the steamed bun box recessed cavity), and the steamed bun box recessed cavity is used for storing the steamed bun steamer, and the steamed bun box recessed cavity has edges around it, which can effectively prevent the steamed bun steamer from sliding off.

[0033] The water to be evaporated is transported into the evaporation water cavity 11 of the heat exchange steam box 1 through the water supplement pipe, the combustion stove is ignited, and the fuel combustion forms a flame, which can heat the bottom of the bottom plate of the heat exchange steam box 1. At the same time, part of the flame and flue gas formed by the fuel combustion enters the flame flue gas collection cylinder 3 and is collected in the flame flue gas collection cylinder 3, and the flame flue gas collection cylinder 3 distributes the high-temperature flue gas into the heat exchange coil 6. The high-temperature flue gas moves in the heat exchange coil 6, and at this time, the high-temperature flue gas in the heat exchange coil 6 uniformly heats the water in the evaporation water cavity 11, and the flue gas after heat exchange in the heat exchange coil 6 is discharged through the external exhaust pipe.

[0034] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
