Steam cooking utensil and water shortage detection method and device thereof

Abstract

The invention provides a steam cooking utensil and a water shortage detection method and device of the steam cooking utensil. The water shortage detection method of the steam cooking utensil includesthe following steps that whether a water tank is installed in place or not is detected, if yes, cooking is conducted, and if not, water shortage is displayed; in the cooking process, time intervals between disconnection and connection of a heating pipe of a steam generator are obtained in real time, and if the time intervals are larger than a first preset value, water shortage is displayed. According to the water shortage detection method, firstly whether the water tank is installed in place or not is detected, so that the common problem that a user tends to forget to plug the water tank is solved, and the water shortage report error is effective; final water shortage detection control is conducted at the steam generator end, so that the detection mode is more accurate, and the probabilityof the water shortage misinformation is lowered, and the problems that water is accumulated in the water tank for a long time due to the fact that water shortage is reported too early, and safety andsanitation of the cooked food are affected are solved.

Description

Technical field [0001] The invention relates to the field of kitchen appliances, and more specifically, to a water shortage detection method of a steam cooking appliance, a water shortage detection device of a steam cooking appliance, and a steam cooking appliance including the water shortage detection device. Background technique [0002] In recent years, people have paid more and more attention to healthy eating, and the requirements for cooking effects have become higher and higher. Gradually, people have realized that cooking (that is, steam heating) can actually meet the requirements very well. Since cooking relies on the huge latent heat released by steam liquefaction to heat the food, it has many advantages: first, the cooking speed is fast; second, due to the easy diffusion of gas, the food is heated fairly evenly, thereby avoiding partial overheating. Coke leads to reduced nutritional value; thirdly, since the oxygen concentration in the air is reduced during steam cooki...

AI Technical Summary

Problems solved by technology

[0003] At present, in steam cooking appliances, the water shortage detection method is mainly: setting a water level detection device in the water tank, such as: using a magnetic float switch to detect the water level, because the float itself needs to be immersed in water for a certain volume to float, so this method When detecting the water level, there is often a lot of water left. The magnetic float switch has already detected the lack of water in the water tank, resulting in inaccurate detection, and a certain amount of stagnant water accumulated in the water tank for a long time will cause bacteria to stink and affect the safety of cooking food; at the same time , the floater is set in the water tank, which makes the manufacturing process of the water tank complicated, the cost is high, and the quality is difficult to guarantee; in addition, if the water delivery mechanism fails, resulting in water shortage in the steam generator, this water shortage detection method cannot be effectively carried out. detection

[0004] In addition, during the use of existing steam cooking appliances, users often forget to install the water tank. The existing water shortage detection method cannot effectively judge whether the water shortage is caused by the lack of water tank installed or the absence of water in the water tank. lack of water
