Steam sterilization dish washing machine and control method thereof

Abstract

The invention discloses a steam sterilization dish washing machine and a control method thereof. The steam sterilization dish washing machine comprises a machine body, a water collecting transferringcomponent, a washing device and a steam generating device, wherein an accommodating cavity is formed in the machine body; a water collecting cavity is formed in the water collecting transferring component; the water outlet end of the washing device communicates with the accommodating cavity; the water inlet end of the washing device communicates with a first soft water outlet of the water collecting transferring component; the water inlet end of the steam generating device communicates with a second soft water outlet of the water collecting transferring component; and a steam outlet of the steam generating device communicates with the accommodating cavity. The steam sterilization dish washing machine using the design has the advantages that the structure is simple; soft water can be supplied for the washing device and the steam generating device; the production cost is reduced; a main control module controls the operation of the washing device so as to perform spraying flushing and preheating on articles to be sterilized; then, the steam generating device is controlled to introduce soft water steam into the accommodating cavity so as to perform high-temperature sterilization on thearticles to be sterilized; the operation energy consumption is reduced; the sterilization effect is better; and the sterilization time can be greatly reduced.

Description

technical field [0001] The invention relates to kitchen and bathroom equipment, in particular to a dishwasher. Background technique [0002] 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. [0003] 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; [0004]...

AI Technical Summary

Problems solved by technology

[0004] 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;

[0005] 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
