Description

A steam sterilizing dishwasher and its control method

technical field

The invention relates to kitchen and bathroom equipment, in particular to a dishwasher.

Background technique

Dishwashers currently on the market generally only have washing and drying functions. Dishwashers can simply sterilize tableware with hot water, but they cannot achieve the disinfection effect of conventional disinfection cabinets. This also affects Chinese consumers' choice of washing dishes. In the medical field, steam is used for disinfection, but these steam generating devices cannot be easily combined with the disinfection device of the dishwasher itself, and the power consumption of the steam generating device is relatively high, so it is not suitable for household dishes disinfection.

In traditional dishwashers, the following problems exist in the combination of steam generating devices. The washing device is connected to an external soft water source, and the items to be sterilized are rinsed with soft water;

The steam generating device is connected to an external general water source, but the general water source has not been treated with soft water, which may easily cause scale in the steam generating device. If the steam generating device is also connected to a soft water source, due to the limitation of the connection structure, two softening devices need to be installed To supply soft water for the steam generating device and the washing device respectively, the structure is complex, and the dishwasher needs to be equipped with corresponding drainage pipes, which leads to the messy arrangement of the overall water transmission of the dishwasher and high production costs;

Furthermore, in the past, the washing device generally used soft water to rinse the items to be sterilized, which could not achieve the purpose of thorough disinfection. If a steam generating device was added, it would also heat and evaporate the water at room temperature, and then sterilize the items to be sterilized. Because ceramic tableware absorbs more heat , it is difficult to quickly heat up the interior. If the temperature rises too slowly, the disinfection operation time will be too long, which cannot meet the needs of users. In the process of steam disinfection, the high-power operation of the steam generating device to generate steam supply requires a large amount of consumption. Electric energy, and traditional disinfection only kills bacteria, but the killed bacteria still stay on the surface of the tableware, which is not clean, which proves that the disinfection effect of this control method is not obvious, and at the same time consumes a lot of energy.
