Control method for steam cooking device, and control system

Abstract

The invention provides a control method for a steam cooking device, and a control system. The control method comprises the steps as follows: firstly, controlling a steam generator to operate when a command of starting the steam cooking device is received, and controlling the switching-on of a water valve and the first preset operation time length of a water pump in sequence so as to filling the pipeline between the steam generator and the water valve with water; secondly, controlling the water pump to supply water to the steam generator when the temperature of the steam generator reaches a preset temperature for cooking through the steam generated by the steam generator; thirdly, controlling the water valve to switch off when the rest cooking time length of the steam cooking device reaches a second preset time length, and controlling the steam generator to process the residual water in the steam generator and the pipeline. According to the control method and the control system with the technical scheme, the segmented control of a cooking process is realized, and the special requirements of different stages during the cooking process are satisfied; besides, the problems that the steam generator is slow in warming and less in steam generating amount caused by the fact that water is supplied to the steam generator before the steam generator is preheated are solved.

Description

technical field [0001] The present invention relates to the technical field of steam cooking equipment, in particular to a control method of steam cooking equipment and a control system of steam cooking equipment. Background technique [0002] With the improvement of living standards, users pay more and more attention to healthy diet, and the requirements for cooking effects are also getting higher and higher, and steam cooking (that is, steam heating) is gradually widely accepted by users due to its many advantages. [0003] Steaming relies on the huge heat released when steam is liquefied to heat food. Its advantages include: [0004] 1) Fast cooking speed; [0005] 2) Due to the easy diffusibility of the gas, the food is heated evenly, thus avoiding the problem of partial overheating and burning, and the reduction of nutritional value; [0006] 3) Since the oxygen concentration in the air is reduced during steam cooking, it avoids the contact of easily oxidized nutrient...

Problems solved by technology

[0013] However, in method one, due to the high deviation of the water pump itself (the deviation is generally 20%), and the lack of precise control of the above cooking process in stages, the amount of steam generated fluctuates, and the temperature of the steam also fluctuates. Not only the cooking effect is greatly reduced, but the safety and reliability of the product is also challenged; in the second method, because the steam generation process cannot be effectively controlled, the steam generation is particularly easily affected by the water level in the water container. The higher the water level, The smaller the amount of generation (because part of the energy is used to maintain the boiling temperature of the water itself), and the steam generated can only reach 100°C at most, and the temperature when it reaches the food will be even lower, and a lot of steam will liquefy and return durin
