Dish washing machine water inlet device and water inlet method

Abstract

The invention provides a dish washing machine water inlet device and a water inlet method, the device comprises a water inlet dual valve and a water softening apparatus, wherein the water inlet dual valve is connected with an outside municipal water route, two water outlet ports are formed in the water inlet dual valve, one water outlet port is connected with a respirator, and the other water outlet port is connected with a dish washing machine water cup; two ends of the water softening apparatus are connected with the respirator and the dish washing machine water cup respectively. According to the dish washing machine water inlet device and the water inlet method, two water inlet routes which are mutually independent and not interfere are realized by the aid of the water inlet dual valve,different water inlet routes are selected according to cleaning objects, the resource of the water softening apparatus is saved while the fruit and vegetable / seafood washing time is saved, the watersoftening regeneration capacity with same specifications is improved by 30% or above, besides, the phenomenon that the use cost is increased due to the fact that the water softening apparatus is usedrepeatedly is avoided.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a water inlet device, in particular to a dishwasher water inlet device and a water inlet method. Background technique [0002] At present, traditional household dishwashers need to use hot water for washing, and the tableware washing process is usually divided into three processes: main washing, cold water rinsing, and hot water rinsing. Since hot water is required for washing, in order to prevent calcium and magnesium ions in the water from forming scales and affecting the cleaning effect when heated, dishwashers are usually equipped with a water softener. The resin in the water absorbs the calcium and magnesium ions in the water, and then enters the inside of the machine to ensure soft water washing and avoid scale formation. The water softener absorbs calcium and magnesium ions in the water through the resin. After absorbing a certain amount of calcium and magnesium ions, it ...

AI Technical Summary

Problems solved by technology

Due to the limited softening capacity of the water softener of the dishwasher and the requirement for the flow rate of the incoming water, generally at 2.5L / min, if the larger water flow rate passes through the water softener when washing fruits and vegetables, the water intake time will be greatly increased, and at the same time It will cause a waste of water softening resources, users will increase the frequency of adding regeneration salt to the water softener, which will increase the cost of use, and will also affect the life of the water softener
