Technical Field

The invention relates to the field of kitchen appliances, in particular to a table type dish washing machine.

Background

The existing dish-washing machines are various in types, and the common dish-washing machines only have one of the two water inlet modes of automatic water inlet or manual water inlet. The top of the dishwasher with a manual water inlet mode is provided with a manual water inlet, and a high-level sensor detects the high water level in the water tank to judge whether the water tank has water. The dish washer with automatic mode of intaking, it adopts the mode that directly inserts running water to come and go the inner bag water injection to get the water, perhaps adopts earlier to get water to the water tank and then go out the mode water injection inner bag from the water tank and get the water. The automatic water inlet dishwasher adopting the latter mode generally has an automatic water inlet provided at the bottom of the water tank, and water enters the water tank from the automatic water inlet.

However, the dish washer with manual water feeding needs manual water feeding, and is inconvenient to use; the automatic water inlet dish washing machine which is directly connected with tap water to inject water into the inner container is adopted, the water injection time to the inner container is long when the tap water flow is small in the washing process, and the water inlet washing efficiency is low; manual water feeding and automatic water feeding can not be selected according to needs, and user experience needs to be improved.

In order to improve products, the industry designs products combining manual and automatic water feeding, but generally manually adds water into a water tank, but the automatic water inlet waterway directly enters the inner container by controlling the on-off of the electromagnetic valve, the on-off of the electromagnetic valve can be controlled only by the water inlet time, under the condition of unstable water pressure, the water quantity entering the inner container through the automatic water adding waterway is extremely inconstant, and has larger water inflow deviation, meanwhile, the automatic water adding waterway can not detect the condition of water source supply interruption, when the automatic water adding waterway is supplied by water source interruption, the water inlet flow can not be cut off in time through the opening and closing of the water inlet electromagnetic valve, the water shortage is judged only through the rear-end washing stage, and the water shortage caused by water source supply interruption or water shortage caused by water leakage of equipment cannot be distinguished through the rear-end judgment, so that the most direct alarm prompt cannot be given to a user.
