Summary of the invention

The object of the invention aims to provide a kind of automatic descaling apparatus and method of operating thereof of steam microwave oven of simple and reasonable, flexible operation, to overcome weak point of the prior art.

Press the automatic descaling apparatus of a kind of steam microwave oven of this purpose design, comprise the control module, guidance panel and the steam generator that are arranged on the body, its architectural feature is that guidance panel is provided with the cleaning function key.

Said control module comprises chip, and chip comprises timer, comparator and memory.

Said steam microwave oven is provided with water spilage tray, water box, and the water box is placed in the water spilage tray, is provided with water level meter switch in the water box; Water pump is arranged between water box and the steam generator.

A kind of control method of automatic descaling apparatus of steam microwave oven is characterized in that may further comprise the steps:

Step 1, the memory of control module receive the information that also storage is transmitted from timer, and this information comprises the t and scale removal time t0 service time of current steam microwave oven; Wherein, use of microwave ovens time t is by timer accumulative total timing when the user uses the steam function of steam microwave oven, and the span of scale removal time t0 is 100 ~ 150 hours;

Step 2, the comparator of control module compares computing, when the service time of steam microwave oven t < during t0, timer picks up counting, and t=t+1s turn-off to finish timer record time t until steam generator; When t=t0, get into step 3;

Step 3, when service time of steam microwave oven during t=t0, the display screen of guidance panel shows to clean to be reminded;

Step 4 after pressing cleaning function key on the guidance panel and carrying out cleaning function, puts 0 with t service time of the current steam microwave oven in the memory;

Step 5 finishes.

Above-mentioned control method also comprises step 6, and this step 6 is positioned at before the step 1,

Whether step 6 after the steam microwave oven energized, at first detects steam generator and works, and having worked when steam generator just gets into step 1, and not working when steam generator just gets into step 5.

The present invention can remind the user to carry out scale removal through increasing the scale removal alarm set of band cleaning function key timely, and can remove the delay incrustation scale in the steam generator automatically, prevents that incrustation scale from spraying the food that pollutes in the cavity, improved sanitation performance.

That the present invention has is simple and reasonable, flexible operation, characteristics that sanitation performance is good.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further described.

Referring to Fig. 3-Fig. 4, the automatic descaling apparatus of this steam microwave oven comprises the control module 6, guidance panel 5 and the steam generator 30 that are arranged on the body 1, and guidance panel 5 is provided with cleaning function key 50.Control module 6 comprises chip, and chip comprises timer 61, comparator 62 and memory 63.

Steam microwave oven is provided with water spilage tray 41, water box 42, and water box 42 is placed in the water spilage tray 41, is provided with water level meter switch 43 in the water box 42; Water pump is arranged between water box 42 and the steam generator 30.

Referring to Fig. 5, the control method of the automatic descaling apparatus of steam microwave oven may further comprise the steps:

Step 1, the memory 63 of control module 6 receive the information that also storage is transmitted from timer 61, and this information comprises the t and scale removal time t0 service time of current steam microwave oven; Wherein, use of microwave ovens time t is by timer 61 accumulative total timing when the user uses the steam function of steam microwave oven, and the span of scale removal time t0 is 100 ~ 150 hours.

Generally speaking, the scale removal time t0 can be provided with different time according to the difference of micro-wave oven sales region, about 100 hours of the general north, about 150 hours of south.

Step 2, the comparator 62 of control module 6 compares computing, when the service time of steam microwave oven t < during t0, timer 61 picks up counting, and t=t+1s turn-off to finish timer t 61 writing time until steam generator; When t=t0, get into step 3.

Judge at first service time, whether t equaled to set the scale removal time t0, when being not equal to, then service time t=t+1s, constantly timing is turn-offed until steam generator and to be finished, and writing time t.

Step 3, when service time of steam microwave oven during t=t0, the display screen of guidance panel 5 shows to clean to be reminded.

Microwave oven displays showed: please clean when service time, t equaled to set the scale removal time t0! The prompting user uses the cleaning function of micro-wave oven strong, removes incrustation scale in the steam generator, so, can remind the user to carry out scale removal timely, effectively raise the cleaning and the utilization rate of steam microwave oven.

Step 4 after pressing cleaning function key 50 on the guidance panel 5 and carrying out cleaning functions, puts 0 with t service time of the current steam microwave oven in the memory 63;

Step 5 finishes.

Above-mentioned control method also comprises step 6, and this step 6 is positioned at before the step 1,

Whether step 6 after the steam microwave oven energized, at first detects steam generator and works, and having worked when steam generator just gets into step 1, and not working when steam generator just gets into step 5.
