Bottom type steam generation device and control method thereof

Abstract

The invention discloses a bottom type steam generation device. The bottom type steam generation device comprises a steam generator, a first temperature sensor and a controller. The steam generator comprises a water container and a heater connected with the water container. The heater is used for heating the water container. The first temperature sensor is used for detecting the temperature of the water container. The controller is used for turning on the heater, so that the water container is heated, and the controller is also used for acquiring the temperature of the water container. The controller is used for judging whether the temperature of the water container is larger than a set temperature or not, and if yes, the controller is used for turning off the heater. According to the bottom type steam generation device, whether the temperature of the water container is larger than the set temperature or not is judged by the temperature sensor so that whether water scale exists in the water container or not can be judged, if yes, the heater is turned off by the controller, and then the water container can be prevented from being damaged. The invention further discloses a control method of the bottom type steam generation device.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a bottom-mounted steam generator and a control method for the bottom-mounted steam generator. Background technique [0002] In recent years, people have paid more and more attention to healthy eating. Steam cooking, as a cooking method that can produce delicious taste and keep nutrition intact, has penetrated into people's daily cooking. Therefore, the steam cooking products utilizing the steam cooking method are welcomed by more and more people. For this type of household appliances, such as steam ovens, etc., at present, the most widely used method is to boil water with a water container at the bottom to generate steam. This implementation method is very simple. Therefore, the products with this bottom-mounted water container structure are adopted so frequently, so the homogeneity of the products we can see in the market is also quite obvious in terms of appearance and stru...

Problems solved by technology

[0005] The disadvantages of the above solution are: 1. Like the detection method using a float, since the float itself needs to be large enough to ensure that it can detect a low water level, the water level detection device is particularly large, which is not conducive to the use of small household appliances. This kind of mechanical detection, its control accuracy is not particularly high, so the water level control is not very good

2. For the method of using a water level probe, the detection resistance is mainly used to confirm whether there is water in the auxiliary water tank, so this solution is only ef
