Description
Technical field
The utility model relates to dish-washing machine technical fields, and the spray of entrained air bubbles in the water flow sprayed can be made by referring specifically to one kind
Arm and application have the cleaning machine of the spray arm.
Background technique
With the increasingly raising of people's living standard, dish-washing machine as a kind of kitchen appliances product, more and more into
Enter family.Dish-washing machine currently on the market be generally divided into it is desk-top, cabinet type, three kinds of slot type, wherein table dish-washer is monoblock type
Absolute construction is typically placed on table top and uses；Cabinet type dish washing machine is also a kind of absolute construction, but needs to be embedded into kitchen cabinet and make
With；Slot type dish-washing machine is combined together with sink, is typically mounted in kitchen cabinet and is used.
Above-mentioned various forms of dish-washing machines be generally water is lifted by water pump and is sprayed to dishes in cleaning space from
And reach cleaning action.For example, application No. is the Chinese patents of CN97236119.7 " Microcomputerized light-controlled full-automatic dish washer ", Shen
Number similar structures please be disclosed for an a kind of Chinese patent " dish-washing machine " of CN00240098.7, in the class formation, spray to dishes
Water flow impact pressure it is weaker, and not enough uniformly, can not be covered by water flow when dishes is more, cause cleaning effect poor.Application
Number for the Chinese patent of CN200710306898.5, " the especially household of the dish-washing machine equipped with the device that can improve clean effect washes the dishes
Machine " it is provided with vapourizing unit, it can be introduced into the intracavitary fluid mist of dish-washing machine for generating, to expand the cleaning surface for spraying to dishes
Product and the uniformity for improving cleansing medium, still, the class formation can not still solve the problems, such as that ejection water flow impact pressure is weak.Application
Number it is provided with ultrasonic wave emitting head device for the Chinese patent " a kind of large size ultrasonic wave automatic dish-washing machine " of 201610795828.X,
And pressure-air is inputted into cleaning solution simultaneously, make the pressure-air of input shape in cleaning solution using ultrasonic wave emitting head device
At bubble, ultrasonic transducer is for supplying energy to cleaning solution, so that the bubbles burst in cleaning solution generates impact force, thus
Improve water flow impact pressure.But in the class formation, the moment generated between ultrasonic wave and high pressure bubble, empty quick-fried phenomenon was needed in water
Middle to maintain, when water flow is by water pump lifting and recycles ejection, high pressure bubble, which is difficult to reach dishes surface, to be ruptured, nothing
Method is suitable for the dishwasher structure of water flow jet formula.In addition, the class formation is also only applicable to the large-scale machine that washes the dishes, it is difficult to suitable
For in home-use dish-washing machine.
Utility model content
