example 1
As shown in fig. 1, a self-feedback controlled steam generator comprises an evaporation tray 1, an electric heater 2 arranged inside the evaporation tray 1, a temperature control switch 3 for detecting the temperature of the bottom of the evaporation tray 1, a water tank 5 for storing water, and an electric water pump 4 for conveying the water in the water tank 5 to the evaporation tray 1;
the water inlet end of the electric water pump 4 is connected with the water outlet end of the water tank 5;
the water outlet end of the electric water pump 4 is connected with the water inlet end of the evaporation pan 1;
the temperature control switch 3 is electrically connected with the electric water pump 4 in parallel;
one end of the temperature control switch 3 connected in parallel with the electric water pump 4 is connected with one end of the electric heater 2;
the other end of the temperature control switch 3 connected in parallel with the electric water pump 4 is used as a first input end A of a power supply;
the other end of the electric heater 2 is used as a second input end B of the power supply.
The working principle of this embodiment is as follows: when the circuit is switched on, the temperature control switch 3 is in a closed state, the electric water pump 4 cannot work, the voltage of the circuit is fully loaded to the electric heater 2, the electric heater 2 starts to heat, and at the moment, the water in the evaporation tray 1 starts to evaporate rapidly. When the water in the evaporation tray 1 is evaporated, the bottom temperature of the evaporation tray 1 can be rapidly increased, and when the bottom temperature of the evaporation tray 1 reaches the set temperature value of the temperature control switch 3, the temperature control switch 3 is in an off state, at the moment, the electric heater 2 and the electric water pump 4 are in a series connection mode, the electric water pump 4 obtains voltage, water pumping is started to be conveyed into the evaporation tray 1, and the temperature of the evaporation tray 1 is promoted to start to be reduced. When the bottom temperature of the evaporating pan 1 is reduced to the set temperature value of the temperature control switch 3, the temperature control switch 3 is closed, the electric water pump 4 is short-circuited, and water pumping is stopped. The voltage of the circuit is fully loaded to the electric heater 2, the electric heater 2 starts to heat, and the electric heater 2 is circulated and reciprocated in the above way, and the orderly work of the evaporator and the electric water pump 4 can still be realized by the action of the temperature control switch 3 without intervention of an electric control program.
In a specific embodiment, the electric heater 2 is a heating resistor.
In a specific embodiment, the bottom of the evaporation pan 1 is provided with a heating through hole 6 for installing a heating resistor; the heating through holes 6 can be arranged at equal intervals, are distributed on the bottom of the evaporation tray 1, and can uniformly heat the evaporation tray 1, so that uneven heating is avoided, and misoperation of the temperature control switch 3 is avoided. The heating resistor is arranged in the heating through hole 6.
In a specific embodiment, the temperature control switch 3 is a normally closed kick type temperature control switch.
In a specific embodiment, the temperature controller includes: a temperature control switch 3 which operates based on the temperature of the electric heater 2 in the evaporation pan 1, a temperature detection probe for detecting the temperature of the electric heater 2, and a controller
The controller is respectively connected with the temperature detection probe and the temperature control switch 3 and is used for controlling the action of the temperature control switch 3 based on the temperature of the electric heater 2.
In a specific embodiment, when the temperature at the bottom of the evaporation pan 1 is detected to be smaller than a set temperature value, the temperature control switch 3 is in a closed state;
when the temperature at the bottom of the evaporation pan 1 is detected to be larger than a set temperature value, the temperature control switch 3 is in an off state.
In this embodiment, since the temperature control switch 3 is connected in parallel with the electric water pump 4, when the temperature control switch 3 is in the closed state, the temperature control switch 3 corresponds to a wire, and the electric water pump 4 is short-circuited, so that the electric water pump 4 is in the inactive state. When the temperature control switch 3 is in the off state, the temperature control switch 3 is equivalent to an open circuit, and at the moment, current passes through the electric water pump 4 and the electric heater 2, so that the electric water pump 4 is in the working state.
When the temperature control switch 3 is in an off state, the electric water pump 4 is in a working state, and the electric water pump 4 conveys water in the water tank 5 to the evaporation pan 1;
when the first temperature control switch 3 is in a closed state, the electric water pump 4 is in a non-working state.
In the embodiment, the device also comprises a first water pipe 401 and a second water pipe 402;
one end of the first water pipe 401 is connected with the water outlet end of the water tank 5;
the other end of the first water pipe 401 is connected with the water inlet end of the electric water pump 4;
one end of the second water pipe 402 is connected with the water outlet end of the electric water pump 4;
the other end of the second water pipe 402 is connected with the water inlet end of the evaporation pan 1.
In this embodiment, the evaporation pan 1, the electric heater 2, the temperature control switch 3, the water tank 5, and the electric water pump 4 are connected as described above. The water tank 5 is filled with water. The first input end A and the second input end B are used for being connected with a power supply. When the circuit is switched on, the normally closed kick temperature control switch is still in a closed state, the electric water pump 4 can not work at the moment, the voltage of the circuit is fully loaded on the electric heater 2, and the electric heater 2 starts to heat. At this time, the water in the evaporation pan 1 starts to evaporate rapidly. When the water in the evaporation tray 1 is evaporated, the temperature of the evaporation tray 1 can be rapidly increased, and when the temperature of the evaporation tray 1 is increased to reach the set temperature value of the normally closed kick type temperature control switch, the switch is tripped. At the moment, the electric heater 2 and the electric water pump 4 are in a serial working mode, the electric water pump 4 obtains voltage, and the water pumping action is started. When water is fed into the evaporation pan 1, the temperature of the evaporation pan 1 is caused to decrease. When the temperature of the evaporating pan 1 is reduced to the set temperature value of the normally closed kick type temperature control switch, the normally closed kick type temperature control switch is closed, the electric water pump 4 cannot work, and water pumping is stopped. The voltage of the circuit is fully loaded to the electric heater 2, and the electric heater 2 starts to heat. The first input end A and the second input end continuously apply voltage, and the steam generator can be in a cycle of heating, evaporating, water supplying, heating and automatically continuously. When the steam generator does not need steam generation, only the voltages at the two ends of the first input end A and the second input end B are needed to be removed.
