Definitions
- the present invention relates to a low-power steam generator, and more particularly, to a low-power steam generator capable of driving with low power by configuring a plurality of heaters having a characteristic that an output decreases as the temperature increases.
- a PTC (Positive Temperature Coefficient) heater means a heater made by using an electric heating element using a PTC thermistor, and PTC means an element having a positive temperature coefficient.
- PTC has a low resistance below the critical temperature, so it is effective to easily increase the amount of heat generated at the beginning of operation, and the electrical resistance increases in proportion to the temperature from the critical temperature to the melting point There is this.
- the output has a characteristic inversely proportional to the resistance.
- the conventional PTC heater has the advantage of being able to keep the temperature almost constant despite fluctuations in external temperature or power supply voltage due to the PTC characteristics as described above. It has the advantage of preventing overheating at the same time while bringing it, so it is widely applied to dryers, warmers, and heaters.
- the present inventors have completed the present invention by developing a low-power steam generator capable of significantly reducing power consumption by operating a plurality of PTC heaters when a specific temperature is reached under the above-described background, and confirming the effect thereof.
- An object of the present invention is to provide a low-power steam generator capable of driving with low power by configuring a plurality of heaters having a characteristic that an output decreases as the temperature increases.
- a pump unit for pumping an external fluid; a heater unit for forming steam by applying thermal energy to the fluid pumped by the pump unit; and a control unit for controlling the pump unit and the heater unit, wherein the heater unit is configured by providing a plurality of heater modules having a characteristic that an output decreases as the temperature increases.
- the heater module may be a positive temperature coefficient (PTC) heater.
- PTC positive temperature coefficient
- control unit may operate any one of the plurality of heater modules first, and then operate any one or more of the heater modules that were not operated among the plurality of heater modules when the heater unit reaches a preset temperature. have.
- the heater unit may further include a sensor module for generating temperature information by checking the temperature of the heater module, and transmitting the temperature information to the control unit.
- the present invention may further include a pipe part communicating the pump part and the heater part and through which an external fluid flows, and the pipe part may be disposed to be wound around the outer surface of the heater part.
- FIG. 2 is an overall view of a low-power steam generator according to an embodiment of the present invention.
- FIG. 3 is a diagram illustrating a driving sequence of a low-power steam generator according to an embodiment of the present invention.
- FIG. 2 is a view of a low-power steam generating device according to an embodiment of the present invention as a whole
- FIG. 3 shows a driving sequence of the low-power steam generating device according to an embodiment of the present invention.
- the low-power steam generator 100 includes a pump unit 110 , a heater unit 110 , a control unit 130 , and a pipe unit 140 .
- the pump unit 110 pumps an external fluid and delivers it to the heater unit 110 through a pipe unit 140 to be described later, and is electrically connected to a controller 130 to be described later and is controlled.
- the heater unit 110 receives the fluid pumped from the pump unit 110, applies thermal energy to the fluid to form steam, and then discharges it to the outside. It is supplied and controlled by being electrically connected to the controller 130 to be described later.
- the heater unit 110 includes a plurality of heater modules 121 and a sensor module 122 .
- the heater module 121 is provided as an element having a characteristic that an output decreases as the temperature increases, and receives power from the outside to generate heat.
- the heater module 121 as described above may be provided as a PTC (Positive Temperature Coefficient) heater or a ceramic heater, but is not necessarily limited thereto. Even if provided, it is free
- the sensor module 122 checks the temperature of the heater module 121 to generate temperature information, and then transmits the generated temperature information to the controller 130 , and is electrically connected to the controller 130 to be described later.
- the heater unit 110 including the plurality of heater modules 121 and the sensor module 122 is operated according to a preset temperature by the control unit 130.
- the detailed process is as follows. As shown in FIG. 3 , at first, the controller 130 operates only one heater module 121 , and then the temperature of the heater module 121 is set from the sensor module 122 to a preset temperature (here, the preset temperature is steam It may be a temperature formed, or it may be a temperature at which the output is greatly reduced.), the heater unit 110 is controlled in such a way that the remaining heater modules 121 are operated. Since the heater module 121 has a PTC effect, it operates at a high temperature with low power.
- the control unit 130 controls the pump unit 110 and the heater unit 110 , and is electrically connected to the pump unit 110 and the heater unit 110 .
- the controller 130 operates one of the plurality of heater modules 121 first, and when it is confirmed from the sensor unit that the heater module 121 has reached a preset temperature, the plurality of heater modules 121 ), the heater unit 110 may be controlled to operate any one or more of the heater modules 121 that were not operated.
- the control method of the control unit 130 as described above uses the PTC characteristic of the heater unit 110 operating with low power at a high temperature. According to this, the heat energy supply to the fluid increases after reaching a preset temperature. The power used can be greatly reduced compared to the case of using one large-capacity heater module 121, so that the steam heater can be configured with low power.
- the pipe unit 140 receives the fluid flowing from the pump unit 110 to the heater unit 110 , and communicates the pump unit 110 and the heater unit 110 .
- the pipe unit 140 may be disposed to be wound around the outer surface of the heater unit 110 . According to the pipe unit 140 to be wound, since the fluid is preheated by the heat generated in the heater unit 110 before being supplied to the heater unit 110, when the fluid is supplied into the heater unit 110, the heater unit ( It is possible to prevent the efficiency of the heater unit 110 from dropping due to a sudden drop in the temperature of the 110 , and furthermore, there is an effect that can extend the life of the heater unit 110 .
- the low-power steam generator 100 including the pump unit 110, the heater unit 110, the control unit 130, and the pipe unit 140 as described above, It has the effect of generating steam with low power. According to this effect, the effect that it is possible to configure a steam generating apparatus wirelessly is expected.
