Method for accurately controlling steam temperature

Abstract

The invention relates to a method for accurately controlling a steam temperature. The method comprises the following steps that a temperature T1 needed by a steam-using chamber is set through a main control unit; a temperature T2 inside the steam-using camber is detected through a second temperature sensor, and the variable quantity of the temperature delta T= T1-T2 is calculated out; a steam heater is started through the main control unit, the main control unit records the required steam amount Q and the required time Ts in the process that the temperature T2 reaches the temperature T1 in the steam-using chamber, and the frequency of temperature variation P1=1 / Ts is calculated out; a steam temperature Td and steam pressure P inside a steam generating cavity are recorded in real time through the first temperature sensor and a first pressure sensor, the main control unit controls the heating power of the steam heater according to the results of P1, Td and P, the conveying amount of the steam is controlled through a flow proportional valve, and therefore the temperature inside the steam-suing chamber is kept constant. According to the method, the steam temperature can be accurately controlled, and the temperature in the steam-using chamber is kept constant.

Description

【Technical field】 [0001] The invention relates to a steam generator, in particular to a steam generator for realizing intelligent constant temperature control and a control method thereof. 【Background technique】 [0002] With the improvement of people's living standards, steam, a highly efficient and energy-saving method, is gradually gaining people's favor, such as steam boxes, steam microwave ovens, steam cleaners, etc., have generally entered family life, and steam saunas are increasingly becoming People use leisure methods for decompression, health care, beauty, and health preservation. However, since each steam appliance is independently designed for a single function, it cannot be used universally. The more space there is, the promotion of steam products is greatly restricted. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to provide a control method for precisely controlling the temperature of the steam in view of the...
