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

Abstract

The invention provides a steam cooking appliance, a water shortage detection method and a water shortage detection device thereof. The water shortage detection method of the steam cooking appliance includes the following steps: detecting whether the water tank is installed in place, if the water tank is installed in place, then cooking, otherwise it shows water shortage; The time interval between on and on, if the time interval is greater than the first preset value, water shortage will be displayed. In the water shortage detection method provided by the present invention, firstly, by detecting whether the water tank is installed in place, the problems often committed by users such as forgetting to insert the water tank are solved, and the water shortage error report is effective; by performing the final water shortage detection control at the steam generator end, the detection method It is more accurate, reduces the chance of false alarm of water shortage, and solves the problem of long-term water accumulation in the water tank caused by premature report of water shortage, which affects the safety and sanitation of cooking food.

Description

technical field [0001] The present invention relates to the field of kitchen appliances, and more specifically, to a water shortage detection method for a steam cooking appliance, a water shortage detection device for 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 also become higher and higher. Gradually, people have realized that steam 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 food, there are many advantages: first, the cooking speed is fast; second, due to the easy diffusion of gas, the food is heated evenly, thus avoiding partial overheating and burning. Third, because the oxygen concentration in the air is reduced during steam cooking, it has a g...
