A kind of energy-saving heating method

Abstract

The embodiment of the invention relates to an energy-saving heating method. The energy-saving heating method includes the steps that a control unit receives a start command input by a user, and according to the start command, a heating control signal and a draught fan control signal are generated; a heating unit heats liquid in a water tank of a heating device according to the heating control signal, so that the liquid in the water tank generates hot steam; a draught fan of the heating device starts according to the draught fan control signal; the hot steam is driven by rotation of the draughtfan, returns to the bottom from the top of the heating device through a gas circulation channel of the heating device to form heating circulating airflow inside the heating device and then heats objects to be heated in the heating device; the control unit monitors the air pressure data and steam temperature data inside the tank of the heating device; when the air pressure data inside the tank reaches an air pressure threshold and the steam temperature data is lower than a preset temperature threshold, the control unit generates a micro decompression command and sends the micro decompression command to a decompression unit; the decompression unit starts according to the micro decompression command to discharge the hot steam of a fixed volume.

Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to an energy-saving heating method. Background technique [0002] At present, most of the heating devices in the prior art use a single heating method, wherein the heating device refers to the equipment that uses hot steam to heat the object to be heated, such as a rice steamer, and uses the heating equipment to heat the water tank in the rice steamer , so that the water in the water tank generates hot steam, and the food is cooked through the rise of the hot steam. When the hot steam is rising, it will condense into water droplets when it encounters a lower temperature cabinet, and hang on the inner wall of the cabinet. In this way, the hot steam cannot be recycled in the rice steamer, and the corresponding cooking time will also be prolonged due to the low utilization rate of the hot steam, thereby increasing cooking energy consumption. [0003] Moreover, when cooking ...

Problems solved by technology

According to the vapor pressure equation, when the internal volume of the rice steamer is constant, when the gas pressure in the rice steamer rises to a certain value, the growth value of the steam temperature in the rice steamer will decrease with the increase of the pressure If you want to keep the steam temperature in the rice steamer at a certain height, you must increase the output power of the heating equipment, which will cause a great waste of energy consumption, and cannot meet the current market demand for energy-saving and environmentally friendly rice steamers. need
