Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, the electronic control steam electric iron comprises an iron bottom heating assembly 01 for generating steam, an electronic controller 03, a water supply device 04 for supplying water under the control of the electronic controller, wherein the iron bottom heating assembly is provided with a water inlet hole, a steam outlet hole and a heating element, a temperature sensor 02 for measuring the actual temperature of the iron bottom heating assembly is arranged on the iron bottom heating assembly, the electronic controller is connected with the temperature sensor, under the control of the electronic controller, the water supply device can supply water to the iron bottom heating assembly through the water inlet hole, and the iron bottom heating assembly can convert the conveyed water into steam and release the steam from the steam outlet hole for ironing through heating of the heating element.
And, the measured actual temperature of the iron bottom heating assembly is provided to the electronic controller by the temperature sensor so that the temperature of the iron bottom heating assembly is controlled by the electronic controller in a first temperature range when the water supply device is not supplying water and in a second temperature range when the water supply device is supplying water.
Specifically, the lower limit value T3 of the second temperature range is greater than the lower limit value T1 of the first temperature range. The upper limit value T4 of the second temperature range is not less than the upper limit value T2 of the first temperature range. Thus, the first temperature range is determined by its lower and upper limits T1, T2; the second temperature range is defined by its lower limit T3 and its upper limit T4. Since the lower limit value T3 of the second temperature range is greater than the lower limit value T1 of the first temperature range, the iron bottom heating assembly consumes less heat when the water supply device is not supplying water, and the temperature of the iron bottom heating assembly is controlled to be in the first temperature range, so that the iron bottom heating assembly is suitable for dry ironing and stores enough heat when steam needs to be output. In case water supply installation supplies water, even make because of supplying water and cause the heat that scalds the bottom of the iron heating element to be consumed rapidly, the temperature gathers and falls, will scald the temperature control of bottom of the iron heating element at the second temperature range promptly, because the lower limit value in second temperature range area is greater than the lower limit value of first temperature range, the start temperature point of restart heating after having improved the bottom of the iron heating element temperature reduction, the start time point of restart heating after having advanced the bottom of the iron heating element temperature reduction, then save temperature sensor and electronic controller's reaction time, ensure that steam can have sufficient temperature, let the bottom plate exert best steam effect, reach better ironing effect.
The water supply of the water supply device can be controlled by an operable control switch, and when the water supply device is used, a user can operate to supply water at any time or stop supplying water according to requirements.
In particular, the iron base heating assembly is equipped with one or more temperature gears, which can be realized by providing the product with corresponding temperature adjustment knobs or buttons, and which can be mechanical or electronic. Because every kind of cloth is fit for ironing in a certain temperature interval, is higher than this interval temperature and easily scalds the cloth, is less than this interval temperature ironing effect again not good, wastes time and energy, consequently, corresponds first temperature range, the second temperature range of arbitrary temperature gear difference of all presetting, and the user uses and can choose for use different temperature gears according to the material of difference often, reaches best ironing effect, labour saving and time saving.
The temperature profile described in fig. 2 can be implemented by the logic path shown in fig. 3.
The solid, meandering line in figure 2 illustrates a temperature curve of the present invention controlling the temperature of the iron base heating assembly in a first temperature range and a second temperature range, with time on the horizontal axis and temperature on the vertical axis. After the iron is ready to be used and the product is connected with the power S1, the temperature sensor measures the temperature of the heating component at the bottom of the iron and transmits the measured temperature to the motor controller S2, the measured actual temperature is normal temperature and is generally smaller than the lower limit value T1 of the first temperature range, and the electronic controller controls the heating component at the bottom of the iron to heat S3.
The iron bottom heating assembly can be heated from the normal temperature until the temperature reaches or exceeds the upper limit value T2 of the first temperature range, and the electronic controller enables the iron bottom heating assembly to stop heating. This time period corresponds to the time interval t 0-t 1 in fig. 2.
The temperature of the iron bottom heating assembly is controlled to the first temperature range S5 or the temperature of the iron bottom heating assembly is controlled to the second temperature range S6 by determining whether the water supply device supplies water S4.
If the water supply device does not supply water to the iron bottom heating assembly, the temperature of the iron bottom heating assembly will fluctuate within a first temperature range (between a lower limit value T1 and an upper limit value T2), this time period corresponding to the time interval T2 to T3 in fig. 2.
First, the iron bottom heating assembly will be cooled when its actual temperature reaches or exceeds the upper limit value T2 (corresponding to the time T1 in fig. 2), until the temperature sensor detects that the actual temperature of the iron bottom heating assembly reaches or is less than the lower limit value T1 of the first temperature range (corresponding to the time T2 in fig. 2), the electronic controller controls the iron bottom heating assembly to heat to raise its temperature to the upper limit value T2. This is repeated thereafter, and the actual temperature fluctuation of the iron bottom heating element corresponds to the time interval t 2-t 3 in fig. 2.
If the water supply means supplies water to the iron bottom heating element, the temperature of the iron bottom heating element will fluctuate within a second temperature range (between a lower limit value T3 and an upper limit value T4), this time period corresponding to the time interval T4 to T5 in fig. 2.
First, when the water supply device starts to supply water to the iron bottom heating assembly at any time when the temperature of the iron bottom heating assembly fluctuates within the first temperature range, if the temperature sensor detects that the actual temperature of the iron bottom heating assembly reaches or is less than the lower limit value T3 of the second temperature range (corresponding to time T3 in fig. 2), the electronic controller controls the iron bottom heating assembly to heat until the temperature of the iron bottom heating assembly is raised to be equal to or greater than the upper limit value T4 of the second temperature range (corresponding to time T4 in fig. 2). And then the electronic controller controls the iron bottom heating assembly to stop heating, and the temperature of the iron bottom heating assembly is reduced until the temperature is reduced to be equal to or less than the lower limit value T3 of the second temperature range, and then heating is started. This is repeated, and the process of the repetition corresponds to the time interval from t4 to t5 in fig. 2.
As described above, after the steam electric iron is electrically started (preheated), the temperature of the iron bottom heating assembly is automatically controlled within the first temperature range or the second temperature range by the electronic controller according to the water consumption condition of the user and according to whether the water supply device supplies water to the iron bottom heating assembly.
