Description
Technical Field
The invention relates to a household kitchen appliance, in particular to a method for controlling the residual water in an inner container of a steam box.
Background
The steam box of the household kitchen appliance adds water into the heating plate through the water tank, and the water is heated and evaporated to heat food. The heating plate is arranged at the bottom of the steam box, the water tank and the heating plate are controlled to enter water through a water inlet device (such as an electromagnetic valve, a water pump and the like), the water inlet device is opened, water flows into the heating plate, the water inlet device is closed, and the water stops flowing in. The control difficulty lies in that: through the controlling of water installations, the velocity of flow is directly proportional with the water level of water tank, and the higher the water level is, the faster the velocity of flow is, and the lower the water level is, the slower the velocity of flow is, so same time of adding water, the inflow that the dish that generates heat obtained is different. In addition, because the power of the heating plate is different in the heating stage and the heat preservation stage when the steam box works, the power required by the heating stage is large and the power required by the heat preservation stage is small under the general condition.
The existing working mode is that the water adding time is fixed, so that when the steam box finishes working, residual water in a heating plate can randomly appear, the amount is large sometimes, the amount is small sometimes, the residual water can be influenced by different voltages, different environmental temperatures and different food material types and amounts, and the residual water cannot be accurately controlled. The residual water can cause secondary pollution and affect the human health if the user does not clean the water in time.
The residual water control of the existing steam box can be seen in the following patent documents: 2018110712782, 2019106409310, 2020104696898, 2021101192174, 2018100920986, 2018115995171, 2021114985598.
