The tankless heater 1 is a hollow body that can be used to contain water. Preferably, the tankless heater 1 is a circular hollow body.
The main pot 2 is a hollow body, and preferably, the main pot 2 is a circular hollow body capable of containing water. The bottom of the mother pot 2 is connected with the top of the instant heating type heater 1, and the interior of the mother pot 2 is communicated with the interior of the instant heating type heater 1. In this embodiment, the diameter of the mother boiler 2 is larger than that of the instantaneous heater 1, so that the mother boiler 2 can accommodate a larger amount of water and a larger steam chamber. The top of the mother pot 2 is open, the upper cover 3 is arranged on the top of the mother pot 2 to seal the top of the mother pot 2, and the upper cover 3 can also be provided with a safety valve 22 to release pressure when the temperature control abnormal pressure in the mother pot 2 is too large, so as to increase the safety.

When the water level of the main boiler 2 contacts the water level probe 8 under the main boiler, the automatic control system closes the water pump and the first water inlet electromagnetic valve 9 to stop water supplement. If the water level of the mother pot 2 rises due to a fault, the system is shut down to stop using the function when the water level contacts the water level probe 7 on the mother pot, so that the use safety is ensured.
The two sub-pots 4 have the same structure and function, and the sub-pots 4 are hollow and can be used for containing water. The sub-boiler 4 is arranged in the main boiler 2, a sub-boiler upper water level probe 10 and a sub-boiler lower water level probe 11 are arranged in the sub-boiler 4, the sub-boiler lower water level probe 11 can control the normal water level, and the sub-boiler upper water level probe 10 can control the abnormal water level. The sub-pan 4 is connected with a second water inlet electromagnetic valve 12 and a steam electromagnetic valve 16, and the second water inlet electromagnetic valve 12 can be connected with the sub-pan 4 through a water inlet coil 13. The number of the sub-boiler upper water level probes 10, the sub-boiler lower water level probes 11, the second water inlet electromagnetic valves 12, the steam electromagnetic valves 16 and the like is at least one corresponding to that of the sub-boiler 4.

When the water level of the sub-boiler 4 contacts the sub-boiler lower water level probe 11, the automatic control system closes the water pump and the second water inlet electromagnetic valve 12 to stop water supplement. If the water level of the sub-boiler 4 rises due to a fault, the system stops using when the water level contacts the water level probe 10 on the sub-boiler, so that the use safety is ensured.
The design of the sub-boiler 4 is that the cold water flows into the sub-boiler 4 through the water inlet coil 13 (pipeline), in order to increase the heat exchange area and the heat exchange efficiency when the sub-boiler 4 is filled with water, the water inlet coil 13 can be changed into straight pipe water inlet, that is, the water inlet coil 13 can also be straight pipe or other type of pipeline.

The water temperature in the primary pot 2 is conducted to the secondary pot 4, when the primary pot 2 finishes the heating process and the system is balanced and stable, the temperature in the secondary pot 4 is 120 ℃, the water level of the secondary pot 4 is higher than the water level of the secondary pot is provided with a second steam chamber 401, when the steam of the secondary pot 4 is used, an operation key (not shown in the figure) is pressed, the steam electromagnetic valve 16 is opened, and the steam of the secondary pot 4 can flow out for use.
When the sub-boiler 4 uses steam, the steam is discharged to reduce the steam pressure, the main boiler 2 keeps 120 ℃, so the heat conduction of the main boiler 2 keeps the steam temperature of the sub-boiler 4, when the steam usage reaches a certain amount, the water is supplemented by the sub-boiler 4 to reduce the temperature of the main boiler 2 to the temperature setting lower limit, the automatic control system starts the instant heating type heater 1 to heat, and when the temperature reaches the upper limit, the instant heating type heater 1 is closed.
The water level of the sub-boiler 4 is reduced by using the steam to bring out water, and the sub-boiler lower water level probe 11 can control and execute a water supplementing program to keep a normal water level. The main boiler 2 does not use steam, so the water level can not be reduced, water supplement is not needed, the instant heating type heater 1 and the main boiler 2 can not generate scale in the heating process, and the heating efficiency of the instant heating type heater 1 can not be reduced.
