Detailed Description

The utility model will be further described with reference to the following examples:

as shown in figure 1, the utility model provides an automatic scale removing method for a steaming device, the steaming device comprises a steam generator box body 1 and a power main switch 3, a drain electromagnetic valve 5 is arranged at the bottom of the steam generator box body 1, a high water level probe 6, a low water level probe 7 and a temperature sensor 8 are respectively arranged on the side wall of the steam generator box body 1, wherein the high water level probe 6 is arranged at the highest water level defined in the steam generator box body 1. A water filling port is formed in the side wall of the steam generator box body 1 and is controlled by a water replenishing electromagnetic valve 4. The descaling device further comprises a descaling controller 2, and the water draining electromagnetic valve 5, the high water level probe 6, the low water level probe 7, the temperature sensor 8 and the water replenishing electromagnetic valve 4 are electrically connected with the descaling controller 2 respectively.

The rear end of the power supply main switch 3 is electrically connected with the input end of the alternating current-direct current converter 9, the output end of the alternating current-direct current converter 9 is provided with an anti-reverse diode 10, and then the anti-reverse diode is respectively connected with two branch circuits, a first branch circuit 14 is connected with the descaling controller 2, a second branch circuit 15 is connected with the rechargeable battery 11, and the positive electrode of the rechargeable battery 11 is connected with the descaling controller 2. The rechargeable battery 11 may be a lithium battery or a lead-acid battery.

The automatic descaling process comprises the following steps:

when the main power switch 3 is powered on, the alternating current flows through the alternating current-direct current converter 9 to be changed into direct current which flows through the first branch circuit 14 and the second branch circuit 15 respectively, at the moment, the descaling controller 2 is in a dormant state, and the second branch circuit 15 charges the rechargeable battery 11.

Secondly, when the main power switch 3 is powered off, the descaling controller 2 senses that the first branch circuit 14 has no voltage signal, the fact that a user turns off the power supply of the equipment and goes to work can be basically judged, the rechargeable battery 11 supplies power to the descaling controller 2, and the descaling controller 2 is started.

And thirdly, when the temperature sensor 8 senses that the water temperature in the steam generator box body 1 is reduced to a specific temperature (60 ℃), the descaling controller 2 controls the drainage electromagnetic valve 5 to be opened, and the scale in the steam generator box body 1 is discharged along with the water flow. Specific drainage time can be set according to the size of the box body, after the drainage time is finished, the descaling controller 2 controls the drainage electromagnetic valve 5 to be closed and the water replenishing electromagnetic valve 4 to be opened, water is replenished to the steam generator box body 1, and when the water level reaches the high water level probe 6, the descaling controller 2 controls the water replenishing electromagnetic valve 4 to be closed.

Because the hot water of 60 degrees is just discharged and the cold water of room temperature (about 15 degrees) is suddenly met, the scale volume on the electric heating tube 13 is shrunk. When the water tank is normally used next time, the electric heating tube 13 is heated, and scale will expand, and the frequent contraction and expansion can make the scale attached to the electric heating tube 13 continuously fall off and be discharged when the water is drained next time.

Two conditions need to be satisfied in opening of drainage solenoid valve 5, the temperature of power master switch 3 outage and in the steam generator box 1 drops to specific temperature (60 ℃), just so guaranteed only just to carry out the drainage operation after steam equipment shuts down, the misdrainage has been avoided, the temperature drops to specific temperature (60 ℃) and discharges water again simultaneously, can avoid the overheated damage that causes the solenoid valve device of temperature, help the expend with heat and contract with cold and drop of incrustation scale again, kill two birds with one stone. After the steam equipment is used, only the main switch needs to be turned off, and automatic drainage and descaling can be realized without secondary cleaning.

The bottom of the steam generator box body 1 is provided with a manual drain valve 12, and when the descaling controller 2 is in failure, the manual drain valve 12 is operated to drain water and descale.

The foregoing is directed to preferred embodiments of the present invention, other and further embodiments of the utility model may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow. However, any simple modification, equivalent change and modification of the above embodiments according to the technical spirit of the present invention may be made without departing from the technical spirit of the present invention.
