Automatic descaling device of steam microwave oven and operation method thereof

Abstract

The invention discloses an automatic descaling device of a steam microwave oven, and an operation method thereof. The automatic descaling device of a steam microwave oven includes a control module, an operation panel and a steam generator all arranged on the main body, wherein cleaning function keys are arranged on the operation panel; the control module includes a chip; the chip includes a timer, a comparator and a storer; a water receiving box and a water box are arranged on the steam microwave oven; the water box is placed in the water receiving box; a water-stage gage switch is arranged in the water box; and a water pump is arranged between the water box and the steam generator. The control method of the automatic descaling device of the steam microwave oven comprises the following steps: step I, information sent from the timer is received and stored by the storer of the control module, and includes the use time t and the descaling time t0 of the current steam microwave oven, wherein the use time t of the microwave oven is the accumulated time counted by the timer when the steam function of the steam microwave oven is adopted. The device and the method have the characteristics of simple and reasonable structure, flexibility in operation, sanitation and excellent performances.

Description

technical field [0001] The invention relates to a steam microwave oven, in particular to an automatic descaling device for a steam microwave oven and an operating method thereof. Background technique [0002] Present steam microwave oven is made up of water box 10, water pump 20, steam generator 30 and cavity 40, as figure 1 Shown; Among them, the water pump 20 draws water from the water box 10 and injects it into the steam generator 30. The steam generator 30 uses electric heating to heat the water pumped by the water pump 20 into water vapor, and the water vapor is sprayed into the cavity 40 to cook the food in the cavity 40 . [0003] The steam generator includes: a water inlet 31 , a casing 33 , a steam outlet 32 ​​, a first heating pipe 34 and a second heating pipe 35 . Wherein, the first heating pipe 34 and the second heating pipe 35 are buried in the casing 33, as figure 2 shown. Because water boils inside the casing 33 of the steam generator to generate water va...

AI Technical Summary

Problems solved by technology

Because water boils inside the casing 33 of the steam generator to generate water vapor, as the use time increases, due to the hardness of the water used, scale will be generated in the steam generator and adhere to the inner wall of the steam generator casing 33, After a long time of use, it will affect the steam generation efficiency

At the same time, part of the scale will be sprayed out from the steam outlet 32 ​​together with the steam, and sprayed into the cavity of the microwave oven, making the food dirty.
