Limescale treatment method for steam heating type cooking appliance

Abstract

The invention discloses a limescale treatment method for a steam heating type cooking appliance, belonging to the technical field of kitchen cooking appliance control. The limescale treatment method is used for solving the limescale detection problem of the existing steam heating type cooking appliance. The limescale treatment method for the steam heating type cooking appliance comprises the following steps of: obtaining the current temperature of a steam generator; adjusting the flow rate of a water pump according to the current temperature of the steam generator; and determining the amount of limescale in the corresponding steam generator according to the adjusted flow rate of the water pump. Compared with a method of judging the amount of limescale according to the service time in the prior art, the limescale treatment method has the advantages that the limescale detection in the limescale treatment method is not affected by factors such as water quality in different regions, the frequency of use of cooking appliances and the like, and the limescale detection result is more accurate. Compared with a method of detecting the amount of limescale by weighing and adding sensors, thelimescale treatment method has the advantages that the limescale detection in the limescale treatment method is realized by depending on the logic operation of a steam generation system per se, the addition of additional detection devices is not needed, the detection cost is low, and the limescale treatment method is easy to implement.

Description

【Technical field】 [0001] The invention relates to the technical field of control of kitchen cooking appliances, in particular to a scale treatment method for steam heating cooking appliances. 【Background technique】 [0002] Steam heating cooking appliances use a steam generator to heat water to generate steam to provide a steam heat source for food cooking. Among them, the steam generator mainly consists of two types: one is a water storage boiler that burns water in a larger space, and the other It is an instantaneous boiler that heats quickly in a small space. No matter what kind of steam generator is used for heating with impure water, scale will be generated. Especially in areas with hard water quality, the problem of scale will be more serious. Scaling in the steam generator will reduce the heating efficiency of the internal heating element, and seriously cause the heating element to overheat and burn out, resulting in safety hazards, and as the scaling time prolongs, i...

AI Technical Summary

Problems solved by technology

Scaling in the steam generator will reduce the heating efficiency of the internal heating element, and seriously cause the heating element to overheat and burn out, resulting in safety hazards, and as the scaling time prolongs, the scale cleaning difficulty will become greater

[0003] In the prior art, many solutions to the scale problem have been proposed, such as the use of magnetization, adsorption, filtration and other means to prevent or remove the scale generated in the steam generator, but the implementation of the above solutions without scale detection is often achieve unexpected results

In the prior art, the manufacturer usually reminds the user to clean the steam generator scale at a fixed time interval on the product manual, but in actual use, the user easily forgets the cleaning time, and due to the difference in water quality in different regions, the fixed time is used to judge amount of scale, can produce large deviations
