Judgment control method of water volume of water box

Abstract

The invention discloses a judgment control method for the water volume of a water box, and the method comprises the following steps: S1, a steam cooking device is started, and a water pump is started;and S2, the real-time current of the water pump is collected, whether the water box lacks water or not is determined according to the relation between the real-time current and the current change setvalue of the water pump, and the current change set value of the water pump is obtained through the water pump and the water box. The real-time current of the water pump is collected, whether the water box lacks water or not is determined according to the comparison relation between the real-time current and the current change set value of the water pump, the water adding point of water shortagecan be accurately judged, a prompt is given in time when the water box lacks water, and the user experience is effectively improved; moreover, the water volume detection function of the water pump iseffectively utilized, accurate judgment and control over the water volume of the water box are achieved under the condition that the cost is not increased, the judgment and control method is simple and easy to operate, and the problems that in the prior art, judgment on water shortage of the water box through floater magnetic induction is inaccurate, and a direct-current water pump only has the effect of pumping water to an evaporator are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of water volume control of a water box, and in particular relates to a method for judging and controlling the water volume of a water box. Background technique [0002] Most of the existing steam cooking devices, such as the water level monitoring function mode of the integrated steaming and roasting machine, use the magnetic induction of the float to judge the water volume of the water box. The float depends on the buoyancy of the water to control the connection with the reed switch, and the error in judging the amount of water is relatively large. For example, when using the steaming function, the water consumption of the water box is relatively large. After the water in the water box is quickly consumed, the steamer and oven detects a lack of water. Since the reed switch can receive the signal from the magnet in the float at this time, it will Mistakenly entered the water shortage alarm function, remindi...

Problems solved by technology

[0004] In view of this, the object of the present invention is to provide a judging and controlling method for the water volume of the water box, which determines whether the water box is short of water through the relationship between the real-time current and the current change setting value of the water pump, and effectively solves the existing problem of water leakage through the magnetic induction of the float. The judgment of water shortage in the box is not accurate and the DC water pump only plays the role of pumping water to the evaporator
