Ls has correlativity.Moreover, the area of the area of gap area 63, the area of slit areas 64 and cut zone 62 with most
The length dimension Ls of wide arc gap size G, the width dimensions Ws of slit areas 64 and slit areas 64 also have correlativity.
That is, as shown in figure 8, for example when increase slit areas 64 width dimensions Ws when, the length dimension of slit areas 64
Ls becomes smaller, and maximum gap size G becomes larger, and the area of gap area 63 increases.In this case, due to protruding portion 61
Width dimensions become smaller, therefore the area of cut zone 62 increases.On the other hand, as shown in figure 9, when the width for reducing slit areas 64
When spending size Ws, the length dimension Ls of slit areas 64 becomes larger, and maximum gap size G becomes smaller, the area of gap area 63
Reduce.In this case, since the width dimensions of protruding portion 61 become larger, the area of cut zone 62 reduces.
Here, using region shown in double dot dash line of the Fig. 7 to Fig. 9 as reference area S.Reference area S is to be connected with each other
The boundary part between straight portion 613 and rake 614 in each protruding portion 61 and formed polygon, be in this case eight
The region of the inside of side shape.The inventors of the present application found that the area of reference area S and gap area 63 and slit areas 64
Area ratio, the numbers of the fine gas bubbles generated in liquid when with by impact portions 60, size and pass through impact portions 60
Liquid flow it is related.
That is, the width dimensions Ws and length dimension Ls of slit areas 64 are for the fine gas bubbles that generate in impact portions 60
Size and the number of specific discharge are affected.That is, process is narrow when the width dimensions Ws of slit areas 64 becomes smaller
The flow velocity for stitching the liquid in region 64 increases, as a result, the size of fine gas bubbles is easy to become smaller.In addition, when slit sizes 64
When length dimension Ls becomes larger, the region for generating fine gas bubbles becomes larger, as a result, the number of the fine gas bubbles of specific discharge increases
Add.
On the other hand, the area of cut zone 62, gap area 63 and slit areas 64 is for by impact portions 60
The flow of unit time is affected.That is, the area of cut zone 62, gap area 63 and slit areas 64 is got over
Greatly, the resistance in impact portions 60 is smaller, and the flow of the unit time by impact portions 60 increases.On the other hand, cut zone
62, gap area 63 and the area of slit areas 64 are smaller, and the resistance in impact portions 60 is bigger, by the unit of impact portions 60
The flow of time is reduced.
Here, the width dimensions Ws and length dimension Ls of slit areas 64 have correlativity.In addition, slit areas 64
Width dimensions Ws and length dimension Ls also has related to the area of cut zone 62, gap area 63 and slit areas 64
Relationship.Therefore, as shown in Figure 10, such as when any in the width dimensions Ws or length dimension Ls that slit areas 64 has been determined
At one, another is automatically also determination.Moreover, the width dimensions Ws and length dimension Ls when slit areas 64 are determined
When, the area of cut zone 62, gap area 63 and slit areas 64 is also determined.As a result, being generated in impact portions 60
The number of bubble, size, the flow of unit time be determined.
In this case, the width dimensions Ws and length ruler of maximum gap size G and slit areas 64
Very little Ls has correlativity.Therefore, the width dimensions Ws and length of slit areas 64 can be managed by maximum gap size G
Spend size Ls.That is, by determining that maximum gap size G, the width dimensions Ws and length dimension Ls of slit areas 64 are determined,
As a result, the area of cut zone 62, gap area 63 and slit areas 64 is also determined.
In this case, maximum gap size G is set in the range of 0.50mm~0.70mm.And
And the width dimensions Ws of slit areas 64 is set in the range of 0.35mm~0.50mm.Moreover, the length of slit areas 64
Size Ls is set in the range of 0.60mm~0.70mm.Moreover, in this case, gap area 63 and slit areas
Total area ratio, i.e. gap area 63 and area of slit areas 64 between the area of reference area S of 64 area
Total area divided by reference area S obtained from value be set to be less than equal to 0.5, specifically 0.3~0.5 range
It is interior.Moreover, the area ratio within the above range in the case where, size, the number of the fine gas bubbles generated in impact portions 60
And the flow equalization of the liquid Jing Guo impact portions 60, it is suitble to washing.
In this configuration, when electromagnetism feed water valve 33 acts and applies tap water to the inlet portion of fine gas bubbles generator 40 51
When pressure, tap water flows to flow path 53.Tap water is the gas dissolution liquid dissolved with the gas based on air.Fine gas bubbles
Generator 40 makes the fine gas bubbles for being less than or equal to 50 μm by mainly generating diameter in the water in flow path 53.Fine gas bubbles generator
40 fine gas bubbles production principle is as follows.
That is, the water by flow path 53 is throttled when passing through throttle 531 first, so that flow velocity gradually increases.Then, exist
When swiftly flowing water collides and passes through impact portions 60, the pressure of the water promptly declines.Decline institute based on the rapid pressure
The cavitation effect of generation, generates bubble in water.
In this case, when flowing water collides impact portions 60 in the vertical tube part 532 in flow path 53,
The water flows around protruding portion 61, to flow to cut zone 62, gap area 63 and slit areas 64 respectively.Between
The sectional area of gap region 63 and slit areas 64 is smaller than cut zone 62, therefore passes through gap area 63 and slit areas
The flow velocity of 64 water further becomes faster.Therefore, the environmental pressure water by gap area 63 and slit areas 64 applied
Close to vacuum state, as a result, the molten air being stored in water becomes fluidized state, it is precipitated as fine gas bubbles.It is passing through as a result,
It has crossed the bubble generated in the water of impact portions 60 and has been less than or equal to 50 μm by subtle chemical conversion diameter, and the amount of the fine gas bubbles increases
Greatly.In this way, a large amount of fine gas bubbles can be generated by making water by fine gas bubbles generator 40.
Here, fine gas bubbles are usually classified according to the diameter of its bubble as follows.For example, diameter is several μm to 50 μm subtle
Bubble is referred to as micron bubble or micro-bubble.In addition, diameter is that tens of nm fine gas bubbles below are referred to as nano bubble
Or ultra micro minute bubbles.Moreover, diameter is that micron bubble and the fine gas bubbles of nano bubble intermediate degree are referred to as micro-nano gas
Bubble.When the diameter of bubble becomes tens of nm, since the wavelength than light is small, can not visual confirmation, liquid becomes transparent.And
And, it is known that these fine gas bubbles are since total interfacial area is big, floats the characteristics such as speed is slow, internal pressure is big, to the object in liquid
The cleaning ability of body is excellent.
For example, the bubble that diameter is 100 μm or more promptly rises in a liquid due to its buoyancy, it is broken in liquid surface
It splits and disappears, therefore the residence time in a liquid is shorter.On the other hand, fine gas bubbles of the diameter less than 50 μm are due to buoyancy
It is smaller, thus the residence time in a liquid is longer.In addition, for example micron bubble shrinks in a liquid and finally crushes, become
Smaller nano bubble.Moreover, part generates the heat and high pressure of high temperature when micron bubble crushes, floating is thus destroyed
In a liquid or the foreign matter of the organic matter that is attached on object etc..Stronger cleaning ability is played as a result,.
In addition, micron bubble is negatively charged, it is easy the positively charged foreign matter of absorption floating in a liquid.Therefore, because
Crushing for micron bubble and the foreign matter being destroyed is adsorbed in micron bubble, slowly float to liquid surface.Then, pass through removing
It is deposited in the foreign matter of liquid surface, to purify liquid.Stronger detergent power is played as a result,.
Here, the pressure of the tap water of average family is 0.1MPa~0.4MPa or so, but common washing machine is most
Big allowable pressure is set to 1MPa.In this case, when the hydraulic pressure of 1MPa is applied to fine gas bubbles generator 40, prominent
