Multi-water pump and dishwasher with multi-water pump

Abstract

The invention discloses a multi-water channel pump and a dish-washing machine having the same. The multi-water channel pump includes a pump housing, a seal diaphragm, a shape memory alloy, and a drivemember; a chamber is defined in the pump housing; the pump housing has a water inlet and at least two water outlets, which are communicated with the chamber; the seal diaphragm is movably arranged onthe water outlets so as to open or close the water outlets; the shape memory alloy is connected to the seal diaphragm so as to drive the seal diaphragm to move according to the deformation of the shape memory alloy; the drive member matches the shape memory alloy so as to control the shape memory alloy to generate the deformation. The multi-water channel pump can achieve random switch of multiplewater channels; compared with the conventional water channel switching valves, the multi-water channel pump combines a pump and a switching valve together, i.e., a water discharging pump, a reversingvalve and a washing pump are integrated on one pump. The multi-water channel pump is simple and compact in structure, can reduce material consumption, can reduce the production cost, is small in size, and can reduce water resource waste.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, and more specifically, to a multi-water channel pump and a dishwasher with the multi-water channel pump. Background technique [0002] Dishwasher, also known as dishwasher or tableware washing machine, is a household appliance that replaces manual washing of dishes such as bowls, plates, cups, plates, and spoons. The working principle of the dishwasher is to shoot hot water dissolved in detergent at high speed to the kitchen utensils to be cleaned, drain the water after washing, and then replace the clean water for cleaning. After cleaning, use its own waste heat or the air heated by the heating element to dry the tableware. Therefore it is also called a dish dryer. [0003] In the related art, since the dishwasher needs water flow to wash the dishes, the water pump is very important for the dishwasher. The dishwasher mainly uses a separate washing pump to provide water d...
