Description

A dishwasher ultraviolet sterilizing module and a dishwasher equipped with the sterilizing module sink

technical field

The utility model relates to a dishwasher, in particular to a dishwasher ultraviolet sterilizing module installed inside the dishwasher for sterilizing residual water in a sink, and at the same time relates to a dishwasher equipped with the ultraviolet sterilizing module. A bowl machine sink belongs to the technical field of dishwashers.

Background technique

Dishwasher is a device that uses nozzles to spray high-pressure washing water to clean tableware. Dishwasher generally includes a dishwasher liner that forms a cleaning room. There is a tableware input port in front of the liner, and a door is set at the tableware input port. The cleaning room is equipped with tableware racks, spraying devices and other components, and the bottom of the liner is also equipped with sinks, washing motors, etc. The spraying device generally uses a rotatable spraying arm, and multiple spraying arms are set on the spraying arm. The spray hole and the spray arm are connected with the waterway, and the water in the waterway is sprayed out through the spray hole on the spray arm to clean the tableware placed in the liner.

When the dishwasher is washing the tableware, different stains on different tableware are mixed with the washing and rinsing of the dishwasher, resulting in peculiar smell. As the heating temperature of the dishwasher increases, the use of rinse aid and brightener will also produce Smell, the smell will spread accordingly. Although the dishwasher continues to drain water and drain away the washing sewage, a certain amount of sewage will still remain in the sink and pipelines. If the machine is opened in time for air circulation, the residual water will aggravate the peculiar smell as time goes on, so it will bring inconvenience to the user to use the tableware.

There are generally two types of sterilization and odor removal methods for existing dishwashers: one is a physical sterilization method, and the other is a chemical sterilization method. Physical sterilization methods include high temperature sterilization, and chemical sterilization methods include dishwashing powder and ozone sterilization. These two sterilization methods have their disadvantages. Among them, the high-temperature sterilization method has the disadvantages of high energy consumption and long time consumption, and the temperature for this method to effectively kill bacteria needs to be above 80 degrees, but some tableware cannot withstand long-term sterilization. The high temperature will cause some tableware to deform; for the dishwashing powder sterilization method, although the dishwashing powder has better decontamination and sterilization ability, most people think that the residue of dishwashing powder will affect the human body, and the dishwashing powder application, it will produce irritating odor under high temperature conditions; ozone sterilization method uses ozone to sterilize, but ozone has peculiar smell, is oxidizing, and is corrosive to dishwasher machine parts. There are also existing dishwashers that change the design to make the motor reach the maximum drainage and increase the amount of flushing water to drain away the sewage, but this will undoubtedly change the structure of the dishwasher, thereby increasing costs and increasing the amount of flushing water This will increase the water consumption of the dishwasher.
