Description

Steam generator

This creation relates to a steam generating device, in particular to a steam generating device capable of generating steam from a mother pot.

Most of the existing steam generating devices are provided with a heater in a container. The water level in the container is higher than the heater. A steam chamber is designed at the upper end of the container. The temperature of the steam chamber is controlled by a temperature controller or a pressure switch. For example 120 ° C or 1 bar. When using steam, the steam pressure in the steam chamber in the container decreases. When the pressure switch detects that the steam pressure is lower than the set value, the heater is turned on. When the steam pressure is higher than the set upper limit, the heater is turned off, or when the steam pressure is reduced, The temperature is also reduced. The temperature detector starts the heater when the temperature is lower than the set temperature, and turns off the heater when the temperature is higher than the set temperature.

However, the existing steam generating device uses a heater to heat the water stored in the container. As the usage time increases, the heater gradually increases the amount of scale adhesion, and the heating efficiency decreases. When the scale adheres to too much, the heater may burn and increase steam generation. The use cost and inconvenience of the device.

The technical problem to be solved by the present invention is to provide a steam generating device which can supply steam and reduce the accumulation of scales.

In order to solve the above technical problems, the technical solution adopted in this creation is to provide a steam generating device, including: a female pot, which is a hollow body and can be used for containing water; at least one heater, the heater is provided In the mother pot; a cover, the cover is arranged on the top of the mother pot; a water level probe on the mother pot, the water level probe on the mother pot is set in the mother pot; a water level probe on the mother pot, the The lower water level probe of the mother pot is arranged in the mother pot; a first water inlet solenoid valve, the first water inlet solenoid valve is connected to the mother pot; at least one child pot, which is a hollow body and can be used for containing Water, the sub-pot is set in the mother pot; at least one sub-pot water level probe is set in the sub-pot; at least one sub-pot water level probe is set in the sub-pot A needle is disposed in the sub-pot; at least one second water-inlet solenoid valve is connected to the sub-pot; and at least one steam solenoid valve is connected to the sub-pot.

The beneficial effect of this creation is that the steam generating device provided by this creation has no external water consumption for the water stored in the mother pot. It is turned on every day when the heating process is performed to exhaust the gas before the water temperature boils. The amount of water is small, and the total amount of water replenished after a long period of use is also a small amount. The amount of scale accumulated in the mother pot is negligible, and the heating power of the heater is not affected by the scale and does not affect the service life.

[First embodiment]

Please refer to FIG. 1 and FIG. 2. The present invention provides a steam generating device, which is a steam generating device for a mother-boiler, including a mother pot 1, at least one heater 2, an upper cover 3, and at least one child pot 4.

The mother pot 1 is a hollow body, and the mother pot 1 can be a circular hollow body, which can be used for containing water. The water level (normal water level) of the mother pot 1 is a first steam chamber 11. The top of the mother pot 1 is open, and the upper cover 3 is disposed on the top of the mother pot 1 to close the top of the mother pot 1 so that the mother pot 1 can form a closed container.

The mother pot 1 is provided with a female pot upper water level probe 5 and a female pot lower water level probe 6. A bottom water solenoid 1 is connected to the bottom or other position of the female pot 1, and when the water level of the female pot 1 leaves When the bottom water level probe 6 of the mother pot, the automatic control system starts the water replenishment pump (not shown) and the first water inlet solenoid valve 7 to replenish water. When the water level of the mother pot 1 contacts the lower water level probe 6 of the mother pot, the automatic control system closes the water supply pump and the first water inlet solenoid valve 7 stops the water supply. If a fault occurs, the water level of the mother pot 1 rises. When the water level contacts the water level probe 5 on the mother pot, the system will stop functioning to ensure safety.

The mother pot 1 can be provided with a temperature controller 8 for controlling the temperature of the mother pot 1. The temperature controller 8 is arranged on the upper cover 3 and extends into the mother pot 1. The temperature setting is, for example, 120 ° C ± 2 ° C, which is approximately equal to the table Pressure 1 BAR. When the water temperature of the mother pot 1 is lower than 118 ° C, the heater 2 is turned on, and when the water temperature of the mother pot 1 is higher than 122 ° C, the heater 2 is turned off. The temperature controller 8 can also be replaced by a pressure switch (not shown). The pressure switch pressure setting is usually about 1 to 1.2 bar. The pressure switch can detect the steam pressure in the mother pot 1 to turn the heater 2 on and off.

Each time the female pot 1 is turned on, the heater 2 is heated from normal temperature to a set temperature. The air in the female pot 1 can be discharged from an exhaust valve 9 provided on the upper cover 3 during the heating process from normal temperature to the boiling stage. 1 After the internal temperature generates steam, the steam flow will close the exhaust valve 9, so that when the temperature of the mother pot 1 reaches a set temperature, the first steam chamber 11 has a corresponding steam pressure. The exhaust valve 9 may also be replaced by a solenoid valve (not shown). The solenoid valve is opened when the heating temperature is lower than the boiling temperature, and the solenoid valve is closed when the heating temperature is lower than the boiling temperature.

A safety valve 10 may also be provided on the upper cover 3. When the heating automatic control system fails, the temperature of the mother pot 1 rises, and when the steam pressure in the mother pot 1 exceeds the set pressure, the steam can be released from the safety valve 10 to ensure that The steam generating device is safe to use.

One or more heaters 2 may be provided. In this embodiment, a design of a double heater 2 is adopted. The heater 2 is an electric heater. The heater 2 is arranged in the mother pot 1. Before the upper cover 3 is not assembled, the heater 2 is assembled on the bottom of the mother pot 1, and between the mother pot 1 and the heater 2, A leak-proof washer 20 is provided to make the heater 2 watertight. The water level of the mother pot 1 needs to be an appropriate distance higher than the top of the heater 2 to prevent the heater 2 from being dry-burned. The mother pot 1 can also be provided with a temperature overheating protection switch (not shown) or other overheating protection devices to ensure safe use.

One or more sub-pots 4 may be provided. In this embodiment, the design of the twin-pot 4 is adopted, and the two-pots 4 are disposed inside the mother pot 1. 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 has a second steam chamber 41 above the water level. The sub-pot 4 is arranged in the mother pot 1. The sub-pot 4 is provided with a sub-pot water level probe 30 and a sub-pot water level probe 40. The sub-pot water level probe 40 can control the normal water level and the sub-pot water level The probe 30 can control the abnormal water level. The sub-pot 4 is connected with a second water inlet solenoid valve 50 and a steam solenoid valve 60. The sub-pot upper water level probe 30, the sub-pot lower water level probe 40, the second water inlet solenoid valve 50 and the steam solenoid valve 60 are provided. The number corresponds to the sub-pot 4, and at least one is set.

When the water level of the sub-pot 4 leaves the sub-pot water level probe 40, the automatic control system starts the water supplement pump (not shown) and the second water inlet solenoid valve 50 to make up water, and cold water can enter the sub-pot 4 from the bottom of the sub-pot 4. When the water level of the sub-pot 4 contacts the sub-pot water level probe 40, the automatic control system closes the water supply pump and the second water inlet solenoid valve 50 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 30 on the sub-pot, the system will stop using the function to ensure safety.

Two sub-pots 4 each have a sub-pot upper water level probe 30 and a sub-pot lower water level probe 40 to control the water level. After the steam generating device completes the heating process, the water temperature in the sub-pot 4 also reaches 120 ° C, and the mother pot 1 is from normal temperature. During the heating process, the steam solenoid valve 60 of the sub-pot 4 is simultaneously opened to exhaust the air in the second steam chamber 41 of the sub-pot 4. When the temperature of the mother pot 1 reaches the boiling temperature, the steam solenoid valve 60 is closed, and the sub-pot 4 is used. When the steam is turned on, the steam solenoid valve 60 is opened, and the steam in the sub-pot 4 is exhausted to execute a steam program. Due to the use of steam, the water level of the sub-pot 4 will be lowered. After the water level of the sub-pot 4 leaves the sub-pot water level probe 40, the automatic control system will start the water supply pump (not shown) and the second water inlet solenoid valve 50. After the water level of the supplementary water contacts the lower water level probe 40 of the sub-pot, the automatic control system closes the supplementary water pump and the second water inlet solenoid valve 50 stops the supplementary water. The hot water stored in the mother pot 1 heats the child pot 4 so that the temperature of the child pot 4 reaches a set temperature so as to supply steam. The mother pot 1 does not use steam, so the water level does not decrease, and it is not necessary to replenish water. And the mother pot 1 does not generate scale, nor does it reduce the heating efficiency of the heater 2.
