The bottom of the mother pot 2 is connected to the top of the instantaneous heater 1, and the inside of the mother pot 2 is communicated with the inside of the instantaneous heater 1. In this embodiment, the diameter of the mother pot 2 is larger than the diameter of the instant heater 1, so that the mother pot 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 disposed on the top of the mother pot 2 to close the top of the mother pot 2. A safety valve 22 may be provided on the upper cover 3 to control the temperature in the mother pot 2. Relieve pressure when abnormal pressure is too high to increase safety.

The instant heater 1 and the female pot 2 can also be connected by welding, because the equivalent is not otherwise Make the icon. One or more sub-pots 4 may be provided. In this embodiment, two sub-pots 4 are provided, and the two sub-pots 4 are disposed inside the mother pot 2.

The female pot 2 is provided with a female pot upper water level probe 7 and a female pot lower water level probe 8, and a first water inlet solenoid valve 9 can be connected to the bottom or other positions of the instant heater 1. When the water level of 2 leaves the lower water level probe 8 of the mother pot, the automatic control system starts the pump (not shown) and the first water inlet solenoid valve 9 makes up water. When the water level of the mother pot 2 contacts the lower water level probe 8 of the mother pot, the automatic control system closes the pump and the first water inlet solenoid valve 9 stops replenishing. If the fault causes the water level of the female pot 2 to rise, when the water level contacts the water level probe 7 on the female pot, the system will stop functioning to ensure that it is safe to use.

The two sub-pots 4 have the same structure and function. The sub-pots 4 are hollow and can be used to contain water. The sub-pot 4 is arranged in the mother pot 2. The sub-pot 4 is provided with a sub-pot water level probe 10 and a sub-pot water level probe 11, the sub-pot water level probe 11 can control the normal water level and the sub-pot water level The probe 10 can control the abnormal water level. The sub-pot 4 is connected to a second water inlet solenoid valve 12 and a steam solenoid valve 16. The second water inlet solenoid valve 12 can be connected to the sub-pot 4 through a water inlet coil 13. The number of water level probes 10 on the sub-pot, the water level probe 11 on the sub-pot, the second water inlet solenoid valve 12 and the steam solenoid valve 16 are set corresponding to the number of the sub-pot 4, and at least one is provided.

When the water level of the sub-pot 4 leaves the sub-pot water level probe 11, the automatic control system starts the pump (not shown) and the second water inlet solenoid valve 12 to replenish water. Cold water can be fed from the bottom of the sub-pot 4 through the water inlet coil 13 Entering the child pot 4, the water inlet coil 13 is located in the mother pot 2. When the water level of the sub-pot 4 contacts the sub-pot water level probe 11, the automatic control system closes the pump and the second water inlet solenoid valve 12 stops the water supply. If the fault causes the water level of the sub-pot 4 to rise, when the water level contacts the water level probe 10 on the sub-pot, the system will stop using the function to ensure safety.

The cold water in the sub-pot 4 is designed to flow into the sub-pot 4 through the water inlet coil 13 (pipe). The purpose is to make the water in the sub-pot 4 increase the heat exchange area and increase the heat exchange efficiency. The water inlet coil 13 can also be changed to a straight pipe. The water, that is, the water inlet coil 13 may also be other forms of pipes such as straight pipes. When each water level is in the normal position, the instantaneous heater 1 is started to start heating, and the water level (normal water level) of the mother pot 2 is the first steam chamber 201. When the water temperature starts to heat, the air in the first steam chamber 201 may be heated. It is discharged from an exhaust valve 14 provided on the upper cover 3. When the temperature of the water in the mother pot 2 reaches the boiling temperature, the exhaust valve 14 is closed. The exhaust valve 14 can also be exhausted by a solenoid valve. The temperature of the female pot 2 can be controlled by a temperature controller 15 which is arranged on the upper cover 3 and extends into the female pot 2. The temperature of the temperature controller 15 is usually set to 120 ° C (approximately 1 bar of the table steam pressure). The controller 15 can turn on and off the instant heater 1 according to a set temperature.

The temperature control of the mother pot 2 can also use a pressure switch (not shown) to control the steam pressure of the mother pot 2 such as 1.2 BAR. The function is the same as using a temperature controller. Since the pressure switch is a prior art, it is not shown in the figure. The temperature of the water in the mother pot 2 is transmitted to the child pot 4. After the mother pot 2 completes the heating process, the system is in a steady state. The temperature in the child pot 4 is also 120 ° C. The water level in the child pot 4 is the second steam chamber 401 When using the steam of the sub-pot 4, press the operation key (not shown) to open the steam solenoid valve 16, and the steam of the sub-pot 4 can flow out for use.

When the steamer 4 uses steam, the steam is discharged to reduce the steam pressure. Since the steamer 2 is maintained at 120 ° C, the heat transfer from the steamer 2 keeps the steamer 4 at a steam temperature. When the temperature of the pot 2 drops to the lower limit of the temperature setting, the automatic control system is turned on and the heating heater 1 is heated, and when the temperature reaches the upper limit, the heating heater 1 is turned off.

The use of steam in the sub-pot 4 will bring out water to lower the water level, and the sub-pot water level probe 11 can control and execute the water replenishment program to maintain a normal water level. The mother pot 2 does not use steam, so the water level will not be lowered, and no replenishment is necessary, so that the instant heater 1 and the mother pot 2 will not generate scale during heating, nor will it reduce the heating efficiency of the instant heater 1.
