The steam cleaner generates steam from the inside, stores the steam, sprays the steam to dissolve the stuck dust and foreign matter, and then removes it.

When the power is supplied, the steam cleaner heats the water stored in the water tank through the heater, and when the inside of the water tank reaches a certain pressure, the pressure regulator discharges the steam to the outside. To be maintained.

In this state, when the user opens the valve, the steam in the water tank is discharged through the injection port and sprayed on the floor to be cleaned, and the steam or sprayed on the floor removes the dents and dry particles attached to the floor and is sucked through the suction port. It is intended to be removed.

When the steam cleaner is completely exhausted, the heater is heated to damage the electric circuit and in some cases there is a risk of fire, so as to prevent the overheating of the heater to warn of water replenishment based on this.

Conventional steam cleaners are provided with an overheat warning device to warn of a lack of water and to prevent overheating of the heater to replenish water to prevent overheating of the heater.

However, the overheat warning device has a problem in that a large number of transistors and capacitors are manufactured.

The present invention has been made to solve the above-mentioned problems, the operation lamp is connected to the thermostat and the water supply lamp to warn of water shortage in parallel and the water supply lamp in series with the Zener diode to turn off the thermostat It is an object of the present invention to provide a steam cleaner water shortage warning device for warning the water shortage by selectively turning on / off the water replenishment lamp according to the breaker voltage of the zener diode.

The configuration of the present invention, which is invented to achieve the above-described object, is as follows.

Steam cleaner water shortage warning device of the present invention is connected in parallel with the thermostat and the temperature controller for heating the water, the temperature of the heater to turn off the heater according to the temperature of the heater when the thermostat is turned off It characterized in that it comprises a water shortage display to indicate the lack of water.

The temperature controller is a thermostat, and the water shortage display part is connected in parallel with the temperature controller and is connected in series with the zener diode and the zener diode arranged to flow current by a breakdown voltage applied when the temperature controller is turned off. And a water shortage lamp turned on by the breakdown voltage of the zener diode.

It is characterized in that it further comprises an operation lamp connected to the thermostat on / off according to the on / off of the thermostat.

According to the present invention configured as described above, the operation lamp connected to the thermostat and the water supplement lamp for warning of water shortage are connected in parallel, and the water supplement lamp is connected in series with the zener diode to break down the zener diode when the thermostat is turned off. It is possible to selectively turn on / off the water replenishment lamp according to the voltage, thereby preventing overheating due to water shortage and reducing manufacturing costs.

Hereinafter, a steam cleaner water shortage warning device according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a steam cleaner water shortage warning device according to an embodiment of the present invention.

Steam cleaner water shortage prevention apparatus according to an embodiment of the present invention, as shown in Figure 1, the power switch 10, the heater 30, the temperature controller 20, the normal operation display and the water supplement display.

The power switch 10 supplies and cuts power to the steam cleaner water shortage warning device according to a user's key operation.

The heater 30 generates steam by heating water stored in a water tank (not shown). Here, when the steam generated by the heater 30 is above a predetermined pressure, the steam is discharged through the injection hole to perform the steam cleaning.

The temperature controller 30 is preferably a thermostat 30, which senses the temperature of the heater 30 and turns off according to the sensed temperature to supply and cut off power to the heater 30. Therefore, when the heater 30 is overheated due to lack of water, the power supplied to the heater 30 is cut off.

One side of the thermostat 20 is connected to the normal operation display unit and the heater 30.

The normal operation indicator has a second diode D2, an operation lamp 50 and a resistor R3, which are connected in series with each other. The second diode D2 has an anode connected to the thermostat 20 and a cathode connected to the operation lamp 50.

Accordingly, when the thermostat 20 is turned on, a DC current is applied to the operation lamp 50 by the second diode D2, and the operation lamp 50 is turned on. On the other hand, when the thermostat 30 is turned off due to overheating of the heater 30, the operation lamp 50 is turned off because the current is cut off.

The water replenishment indicator is connected in parallel with the thermostat 20, while having a first diode D1, a zener diode Z D , a water replenishment lamp 40, and a resistor R, which are connected in series with each other. . The first diode D1 has an anode connected to the power switch 10 and the other end connected to the zener diode Z D to apply a DC current to the water replenishment lamp 40.

When the thermostat 20 is turned off due to overheating of the heater 30, the zener diode Z D flows as a breakdown voltage or more is applied. Accordingly, the water replenishment lamp 40 is turned on.

On the other hand, when the Thermos taeteu 20 is turned on, since there is less than a breakdown voltage Zener diode (Z D), Zener diodes (Z D) are no current flows, so that water filling the lamp 40 is off.

On the other hand, when the current flows through the zener diode (Z D ), the resistor (R) limits the current so that no current above a certain current flows, and the voltage applied to both ends of the zener diode (Z D ) maintains a constant voltage.

That is, when the thermostat 20 is turned off and the reverse voltage is applied above the breakdown voltage, the zener diode Z D causes the water supplement lamp 40 to be turned on by flowing a current.

Hereinafter, an operation process of the steam cleaner overheat warning device according to an embodiment of the present invention will be described.

When the user operates the key to turn on the steam cleaner power switch 10, power is supplied. Accordingly, the heater 30 is turned on to heat the water stored in the water tank to generate steam. In addition, a DC current flows into the operation lamp 50 through the second diode D2, and the operation lamp 50 is turned on.

In this process, when water is insufficient in the water tank, the heater 30 is overheated, and the thermostat 20 senses the temperature of the heater 30 and is turned off when the temperature exceeds the predetermined temperature.

When the thermostat 20 is turned off, the power supplied to the heater 30 is cut off and the operation lamp 50 is also turned off.

On the other hand, Thermos taeteu 20 is as turned off, the Zener diode (Z D) is applied to more than the breakdown voltage, reverse voltage, so that the zener diode (Z D), the current flows in filling the lamp 40 through the water replenishment Lamp 40 is turned on. In this process, the current is limited by the resistor (R).

That is, the steam cleaner overheat warning device according to the embodiment of the present invention, when the thermostat 20 is turned off due to the overheating of the heater 30 due to the lack of water, the operation lamp 50 is turned off and the water shortage lamp 40 is turned off. Can be turned on to warn the user of water shortages.

Although the present invention has been described with reference to the embodiments illustrated in the drawings, this is merely exemplary and various modifications and equivalent other embodiments are possible for those skilled in the art to which the art pertains. I will understand. Therefore, the true technical protection scope of the present invention will be defined by the claims.
