In any two spray arm, second interface is also two, and two second interfaces are connected with two spray arms respectively, so as to
Realize alternating mold cleaning formula of two spray arms under heating, non-heated mode.For example:
In the washing liner 1 of dish-washing machine 100 spray can be not provided with using lower spray arm 23, middle spray arm 22 is only arranged
The scheme of arm 21 is drenched, wherein second interface can be two, the spray inlet 231 of one of second interface and lower spray arm 23
It is connected, another second interface is connected with the spray inlet 221 of middle spray arm 22, and three kinds of friendships when non-heated mode may be implemented
For mold cleaning formula: upper spray arm 21 sprays cleaning model, and middle spray arm 22 sprays cleaning model, upper spray arm 21, middle spray arm 22
Cleaning model is sprayed simultaneously.Similarly, in its heating mode, above-mentioned three kinds of alternatings mold cleaning formula also may be implemented, as a result, in this reality
It applies in example, the alternating with six kinds of modes is washed altogether.
5th embodiment according to the present utility model is described below:
According to the dish-washing machine 100 of the utility model embodiment, including upper spray arm 21, middle spray arm 22, lower spray arm 23
In any two spray arm, second interface is one, and two spray arms are connected with the second interface, so as to realizing plus
Double spray arms when heat pattern and non-heated mode spray cleaning model.As a result, in the present embodiment, there are two types of wash mould for tool altogether
Formula, i.e., the heating of double spray arms are washed and non-heated mold cleaning formula.
6th embodiment according to the present utility model is described below:
According in the washing liner 1 of the dish-washing machine 100 of the utility model embodiment can using be only arranged lower spray arm 23,
One in middle spray arm 22 or upper spray arm 21, wherein second interface can be one, second interface and lower spray arm 23,
One in middle spray arm 22 or upper spray arm 21 is connected, and single spray arm when heating mode and non-heated mode may be implemented
Spray cleaning model.As a result, in the present embodiment, there are two types of washing mode, i.e., the heating of corresponding spray arm is washed to be added tool with non-altogether
Hot wash mode.
To sum up, according to the dish-washing machine of the utility model embodiment 100, by the way that shunt valve 4 is arranged, so as to realize not
Switching under same washing mode to washing water, under non-heated mode, washing water is not passed through heating device 3, not only may be used in this way
To reduce the resistance to water-flow in the non-heated period in flow promoter system to a certain extent, flow rate of water flow is improved, accelerates cleaning speed
And cleannes, lifting system scourability, and under non-heated mode, the flow path of the opening and closing of heating device 3 and washing water can be with
Individually controlled respectively, dish-washing machine 100 it is more convenient to use.In addition, water function will be divided to concentrate in a shunt valve 4,
So that bifurcation structure is compact, circuit lines are shortened, and control method is simple.
