When the existing dish washer washes dishes, water is usually injected into an inner container of the dish washer, and then the water is pumped into a spray pipe in the dish washer through a circulating water pump to wash the dishes. In order to improve the washing effect of greasy tableware, a dishwasher usually uses an electric heater or a heat pump system to heat washing water, and then sprays the washing water to the tableware.
An upper spray arm and a lower spray arm are generally arranged in the current dishwasher liner; when the dishwasher is in operation, the washing pump conveys water with higher pressure to the upper and lower spray arms, the water is sprayed out from the spray arms to wash tableware and then returns to a cup at the bottom of the dishwasher, and the washing pump conveys the backflow water to the upper and lower spray arms again to complete a cycle. In order to achieve a better washing effect, three sprayers, namely bottom spraying, middle spraying and top spraying, are arranged in some dish washing machines, the bottom spraying is positioned at the bottom of an inner container of the dish washing machine, the middle spraying is positioned at the bottom of an upper shelf of the dish washing machine, and the upper spraying is positioned at the top of the inner container of the dish washing machine. The three sprayers act the water pumped by the washing pump on the tableware to wash the tableware.
Because of the large number of pipelines leading to each sprayer, large water and electric energy are consumed when the sprayer is opened at the same time. Generally, in order to save energy, each sprayer usually does not work at the same time, in this case, a shunt valve is needed to shunt water pumped by the washing pump to drive the corresponding sprayer to work, and the shunt valve can generally control one or two of the sprayers to work in a matching manner. In the prior art, due to the limitation of the structure of the shunt valve, the on-off of the three sprayers cannot be controlled by most shunt valves respectively, so that few washing modes can be realized, layered washing and combined washing are difficult to realize, and the reduction of energy consumption and water consumption of the dish washing machine is not facilitated.
With increasing emphasis on energy conservation and consumption reduction of household appliances, waste of heat energy in each washing stage in the dishwasher is also concerned. Some dish washers directly discharge hot water in the washing process, and cannot recycle heat energy in the washing process, so that waste of the heat energy is caused; if set up the heat exchange system of dish washer alone, then need additionally to increase pipeline and control valve, can increase the space that occupies, make the structure in the dish washer more complicated, be unfavorable for production and assembly.
