The utility model discloses a steam generator, including box 1, steam outlet 11 has been seted up at the top of box 1, carries steam to the steam space of needs (for example evaporate the rice car or evaporate the room that evaporates equipment such as cabinet) through this steam outlet 11. An inner chamber 12 is provided in the housing 1, which inner chamber 12 also serves as a combustion chamber, i.e. a space filled with the flame of the burner. One end of the inner chamber 12 has an open mouth exposed at the end of the case 1 for connection of the burner 2, as shown in fig. 3. In a particular application, the flame produced by the burner 2 is located within the interior chamber 12. In this embodiment, the cavity 12 is substantially cylindrical and has a closed end at the end away from the open end. Typically, the perimeter of the open mouth is sealingly secured to the tank 1.

A first conduit 14 connected to one side of the lumen 12. In this embodiment, the two are continuously welded together at the junction, with the first conduit 14 communicating with the lumen 12. The first conduit 14 has a plurality of conduits that are aligned along the length of the lumen 12, as shown in FIG. 1. A second conduit 15 connected to the other side of the lumen 12 and continuously welded together at the junction, the second conduit 15 communicating with the lumen 12. The second conduit 15 has a plurality of tubes arranged along the length of the lumen 12 as shown in fig. 1. The bottom ends of the first and second guide ducts 14 and 15 are connected to a tail gas chamber 16. Specifically, the first conduit 14 and the tail gas cavity 16 are continuously welded together at the joint, and the first conduit 14 is communicated with the tail gas cavity 16; the second conduit 15 and the exhaust gas chamber 16 are continuously welded together at a junction, the second conduit 15 and the exhaust gas chamber 16 being in communication. The tail gas cavity 16 is positioned below the inner cavity 12, and the tail gas cavity 16 penetrates through the wall of the box body 1 to be communicated with the outside. In a specific application, the hot flue gas in the inner cavity 12 flows into the tail gas cavity 16 through the first guide pipe 14 and the second guide pipe 15 respectively and then is discharged out of the box body 1. Because the inner cavity 12 is located in the box body 1, namely, water is stored in the peripheral space outside the inner cavity 12, and the flame of the burner 2 is directly combusted in the inner cavity 12 isolated by the inner cavity in the water body, obviously, the hot flue gas generated by the burner 2 directly participates in heat exchange at the position close to the water surface in the box body 1, the heat utilization rate is improved, and the energy consumption is reduced. It will be appreciated that it also enables the time to generate steam to be reduced.

The replenishing tank 3 is communicated with the tank body 1 through a first pipeline 31, as shown in the figure, one end of the first pipeline 31 is connected with the middle part of the replenishing tank 3, and the other end of the first pipeline 31 is connected with the middle part of the tank body 1. The first pipe 31 is mainly used to replenish the tank 1 with water. The water replenishing tank 3 is communicated with the tank body 1 through a second pipeline 32, as shown in the figure, one end of the second pipeline 32 is communicated with the top of the water replenishing tank 3, the other end of the second pipeline 32 is communicated with the top of the tank body 1, and the second pipeline 32 is mainly used for balancing pressure, so that water in the water replenishing tank 3 flows into the tank body 1. The water inlet pipe is communicated with the water replenishing tank 3. The water inlet pipe 4 is used for supplying water to the water supply tank 3. Generally, a float valve is provided in the refill tank 3, and when the water level in the refill tank 3 drops to a certain height, the float valve is opened to allow the water in the inlet pipe 4 to flow into the refill tank 3.

In one embodiment, a drain pipe 17 is provided at the bottom of the tank 1, and a valve is installed on the drain pipe 17 as a drainage structure for draining water in the tank 1.

In one embodiment, the water inlet pipe 4 is communicated with the box body 1 through an electromagnetic valve. When the electromagnetic valve is opened, water in the water inlet pipe directly flows into the box body 1 and can be used for cleaning the inside of the box body 1. Normally, the solenoid valve is in a normally closed state, and water in the water inlet pipe flows into the tank 1 through the makeup tank 3.

In one embodiment, as shown in fig. 1, the engagement position of the first catheter 14 with the inner cavity 12 is located at the upper part of the inner cavity 12; the position of engagement of the second conduit 15 with the lumen 12 is located at the upper part of the lumen 12. By adopting this configuration, the hot flue gas is facilitated to flow out through the first duct 14 and the second duct 15 because the joining position is at the upper portion.

As seen from the figure, the first conduit 14 and the second conduit 15 extend downwards, and the water at the upper part in the box body 1 is firstly heated by the hot flue gas with relatively high temperature, so that the effective utilization of heat is ensured.

In one embodiment, as shown in fig. 3, the first conduit 14 is curved and the second conduit 15 is curved.

In one embodiment, the burner 2 has a flame generating rod-like structure that extends into the interior chamber 12, and the burner 2 of this configuration is also referred to as a flame rod.

In one embodiment, the top of the housing 1 is provided with a rupture disc safety device 51. The top of the water replenishing tank 3 is provided with a rupture disk safety device 52.

Referring to fig. 1, in one embodiment, the rear end of the rear air chamber 16 is exposed from the top of the cabinet 1 to communicate with the outside. By adopting the structure, the residual heat of the flue gas (tail gas) can be fully utilized.

In one embodiment, a pressure gauge connecting pipeline 6 is further arranged at the top of the box body 1.
