As shown in Fig. 7 and Fig. 9, variant part 62 is configured to, from the medial surface in the portion that is inserted into 61 towards downstream-side channel The center in the diameter direction of component 60 protrudes.In this case, variant part 62 is configured to the flowing side along downstream-side channel 42 To, namely downstream-side channel component 60 length direction extend slender rod shaped, i.e., so-called ribbed shape.In present embodiment In the case of, there are four variant parts 62 for the tool of downstream-side channel component 60.As shown in figure 9, each variant part 62 is along the portion that is inserted into 61 The circumferential direction of inner peripheral surface equally spaced configure.

As shown in figure 8, being inserted into being inserted into for downstream-side channel component 60 in the insertion section of upstream-side channel component 50 53 When in portion 61, variant part 62 is deformed by the compressing of the peripheral surface in the portion that is inserted into 61.Therefore, it is deformed around insertion section 53 Portion 62 presses.Upstream-side channel component 50 is pressed with downstream-side channel component 60 in insertion section 53 and the portion that is inserted into 61 each other as a result, It is connected in the state of compeling.

In this case, it is inserted into portion 61 and is formed as from the upstream side toward the downstream side that internal diameter size is continuously Conical Taper Pipe shape gradually decrease, so-called.That is, the internal diameter size ratio for the upstream end thereof being inserted into portion 61 is inserted into portion The internal diameter size of downstream end in 61 is big, and bigger than the outer diameter of insertion section 53.Moreover, each variant part 62 is along Taper Pipe The medial surface for being inserted into portion 61 of shape is arranged obliquely, so that the distance between each variant part 62 becomes from the upstream side toward the downstream side It is narrow.

In this case, the internal diameter size of the entrance side, namely upstream end thereof that are inserted into portion 61 is than insertion section 53 Outer diameter is big, therefore convenient for insertion section 53 to be inserted into the portion of being inserted into 61.Moreover, being inserted into insertion section 53 to be pressed into When in portion 61, the lateral surface of insertion section 53 is moved along inclined variant part 62, therefore convenient for making center and the quilt of insertion section 53 The center of insertion section 61 is consistent.That is, in this case, convenient for make upstream-side channel 41 diameter direction center and downstream effluent The center in the diameter direction on road 42 is consistent.As a result, operation when being convenient for insertion section 53 being inserted into the portion 61 of being inserted into.This Outside, variant part 62 can also be replaced, structure identical with variant part 62 is arranged in the peripheral part in insertion section 53.Also can as a result, Obtain function and effect identical with variant part 62.

As shown in Fig. 2 and Fig. 8, under fine gas bubbles generator 40 is inserted into the insertion section of upstream-side channel component 50 53 Trip effluent circuit unit 60 is inserted into portion 61 and upstream-side channel component 50 and downstream-side channel component 60 is made to be connected to each other simultaneously In the state of assembling, it is assembled into mounting portion 25.Downstream-side channel component 60 in fine gas bubbles generator 40 is stored In the second incorporating section 252.

As shown in Fig. 2, by the tip portion of private water supply pipe 22 to the first incorporating section 251 and the second incorporating section 252 Bottom side pressing fine gas bubbles generator 40.Fine gas bubbles generator 40 is connected with watertight state each other with mounting portion 25 as a result, It connects.In this case, the outer diameter of downstream-side channel component 60 is bigger than the internal diameter of interconnecting part 253.Therefore, fine gas bubbles generator 40 will not pass through flow path 241 side of the interconnecting part 253 to water supply oral area 24 from the first incorporating section 251 and 252 side of the second incorporating section It falls off.

In this configuration, when feed water valve 23 acts and applies tap water pressure to the upstream end thereof of fine gas bubbles generator 40 When, tap water flows to downstream-side channel 42 from upstream-side channel 41.Tap water is the gas dissolved with the gas based on air Dissolve liquid.Fine gas bubbles generator 40 makes by generating a large amount of diameter in the water in flow path 41,42 less than or equal to 500nm's Fine gas bubbles, more preferably diameter are less than or equal to the fine gas bubbles of 250nm, and further preferably diameter is less than or equal to 100nm Fine gas bubbles.It is as follows that the fine gas bubbles of fine gas bubbles generator 40 generate principle.

It is throttled when by the throttle 411 of upstream-side channel 41 first by the water in fine gas bubbles generator 40, To which flow velocity gradually increases.Then, when swiftly flowing water collides and passes through impact portions 70, the pressure of the water promptly under Drop.Decline the generated effect that cavitates according to the rapid pressure, generates bubble in water.

In this case, when in the vertical tube part 412 in upstream-side channel 41 flowing water collide collision When portion 70, which flows around protruding portion 71, to flow to cut zone 413, gap area 414 and slit respectively Region 415.Gap area 414 and the sectional area of slit areas 415 pass through gap area than 413 smaller of cut zone 414 and the flow velocity of water of slit areas 415 further become faster.

Therefore, the environmental pressure water by gap area 414 and slit areas 415 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 has passed through impact portions 70 as a result, Water in the bubble that generates it is most of 500nm is less than or equal to by subtle chemical conversion diameter, more preferably diameter is less than or equal to 250nm, further preferably diameter are less than or equal to 100nm, and the amount of the fine gas bubbles increases.In this way, by making water pass through Fine gas bubbles generator 40 can generate a large amount of fine gas bubbles, the supply without obtaining gas from outside.

Next, referring especially to Fig. 2, installation and dismounting operation to fine gas bubbles generator 40 illustrate.At this In embodiment, operating personnel can be by being operable to dismount from the outer side of rinse bath 12 and the either side of private side Fine gas bubbles generator 40.First, to installing fine gas bubbles generator by the operation carried out from the outer side of rinse bath 12 40 the case where, illustrates.Here, be already installed on the wall surface 121 of rinse bath 12 with feed water inlet portion 24 and mounting portion 25, And premised on not removed from wall surface 121.

In this case, operating personnel is first by the operation carried out from the outside of rinse bath 12, relative to from installation The outside mounting portion 25 outstanding of hole 122 to rinse bath 12, fine gas bubbles generator 40 is inserted into incorporating section 251,252. Next, the top end part of private water supply pipe 22 is inserted into the receiving portion 254 of mounting portion 25 by operating personnel.Operation people as a result, Fine gas bubbles generator 40 can be mounted on private water supply path B by member by the operation carried out from the outer side of rinse bath 12 On.

In this case, can also be configured to keep the outer diameter of seal member 27 more slightly larger than the internal diameter of receiving portion 254, to By the elastic force of seal member 27, the top end part of private water supply pipe 22 is made to be pressed into the receiving portion 254 of mounting portion 25.In addition, Can also the inner peripheral surface of the receiving portion 254 of mounting portion 25 with formed on the peripheral surface of the top end part of private water supply pipe 22 it is embedding each other The screw thread of conjunction, and the top end part of private water supply pipe 22 is screwed into the receiving portion 254 for being fixed on mounting portion 25.

In this case, operating personnel can be by being inserted into fine gas bubbles to from 122 mounting portion 25 outstanding of mounting hole The top end part of generator 40 and private water supply pipe 22 is assembled, therefore is convenient for operation.Therefore, by from rinse bath 12 outer side is operable to the mode of installation, in the state that rinse bath 12 is not accommodated in babinet 11, is namely making It is more efficient in assembling operation when making dish cleaning machine 10.

In addition, operating personnel also can for example as described as follows by the operation that is carried out from the outer side of rinse bath 12 come Dismantle fine gas bubbles generator 40.That is, such as operating personnel is from mounting portion 25 when that will remove fine gas bubbles generator 40, first The top end part of private water supply pipe 22 is removed from receiving portion 254.Later, such as from 254 side of receiving portion the hooks such as rodlike component are inserted into Firmly impact portions 70, and extract fine gas bubbles generator 40 out to 254 side of receiving portion.

Next, to the operation by being carried out from the private side of rinse bath 12 come the case where installing fine gas bubbles generator 40 It illustrates.Here, being already installed on the specified position, simultaneously in the space between babinet 11 and rinse bath 12 with internal feed pipe 22 And premised on not removed from the specified position.In this case, operating personnel leaves in water supply oral area 24 and mounting portion 25 In the state of the wall surface 121 of rinse bath 12, fine gas bubbles generator 40 is inserted into the incorporating section 251,252 of mounting portion 25.

Next, operating personnel is in the state that fine gas bubbles generator 40 is accommodated in mounting portion 25, by mounting portion 25 It is inserted into from the private side of rinse bath 12 towards outer side in mounting hole 122, and the top end part of private water supply pipe 22 is inserted into In the receiving portion 254 of mounting portion 25.Then, water supply oral area 24 and mounting portion 25 are fixed on by operating personnel by the way that screw 15 is equal On wall surface 121.Operating personnel can be by the operation that is carried out from the private side of rinse bath 12 by fine gas bubbles generator as a result, 40 are mounted on the B of private water supply path.Moreover, operating personnel can be by carrying out step contrary to the above come from private water supply Fine gas bubbles generator 40 is removed on the B of path.

In this case, operating personnel, which is not necessarily to the taking-up rinse bath 12 out of babinet 11, can dismount fine gas bubbles generation Device 40.Therefore, clear being difficult to take out from babinet 11 by way of being dismounted the operation carried out from the private side of rinse bath 12 In the state of washing trough 12, user self-changeable fine gas bubbles generator 40 of such as dish cleaning machine 10 the case where inferior more have Effect.

Next, referring to Fig.1, being illustrated to the operation content of dish cleaning machine 10.In the present embodiment, tableware is clear Washing machine 10 is after bringing into operation, and first in the state of closing drainage path D by switching valve 35, open feed water valve 23 is to open Logical water supply path A, B, the thus water filling into rinse bath 12.In addition, although circulating path C is the state opened at this time, pump 36 can both act and can not also act.Moreover, being flowed into the tap water in the B of private water supply path through meticulous from feed water valve 23 When microbubble generator 40, become containing diameter be less than or equal to 500nm, more preferred diameter be less than or equal to 250nm, further it is excellent The water of fine gas bubbles of the diameter less than or equal to 100nm is selected, that is, is become containing a large amount of a diameter of nano level fine gas bubbles Fine gas bubbles water, and be injected into rinse bath 12.

Here, before operation starts, cleaning agent has been put into rinse bath 12 from user.Therefore, it is supplied to rinse bath Fine gas bubbles water in 12 mix in rinse bath 12 with cleaning agent, to generate containing cleaning agent and it is a diameter of it is nano level carefully The cleaning solution of microbubble.

When the fine gas bubbles water i.e. cleaning solution that are held in rinse bath 12 reach specified amount, dish cleaning machine 10 closes It closes feed water valve 23 to stop supplying water into rinse bath 12, starting pump 36 later makes the fine gas bubbles water being held in rinse bath 12 follow Ring.The cleaning solution sprayed as a result, from the nozzle tip portion 322 of washer jet 32 sprays to tableware class 1 repeatedly, to tableware class 1 It is cleaned.

Here, fine gas bubbles are usually classified according to the particle diameter of its bubble as follows.For example, particle diameter is several μm to a 50 μm left sides Right, namely micron-sized bubble is referred to as micron bubble or micro-bubble.On the other hand, particle diameter is hundreds of nm to number Ten nm or less, namely nano level bubble are referred to as nano bubble or ultra micro minute bubbles.

It, can not be visual due to smaller than the wavelength of light when the particle diameter of bubble becomes hundreds of nm to tens of nm or less Confirm, liquid becomes transparent.Moreover, with bubble phase ratio more than micron order, nano level fine gas bubbles have total interfacial area Greatly, float the characteristics such as speed is slow, internal pressure is big.For example, particle diameter for micron-sized bubble due to its buoyancy and in a liquid Promptly rise, ruptures and disappear in liquid surface, therefore the residence time in a liquid is shorter.On the other hand, particle diameter For nano level fine gas bubbles since buoyancy is smaller, thus the residence time in a liquid is longer.

Even if in the case where being cleaned without using the cleaning agent containing interfacial agent etc., compared with tap water, contain Cleaning performance can also be improved to a certain extent by having particle diameter to be the fine gas bubbles water of nano level fine gas bubbles.However, with making The case where being cleaned with the common cleaning solution without fine gas bubbles is compared, by as shown in Figure 11 by particle diameter be receive The fine gas bubbles 91 of meter level are mixed into the cleaning solution dissolved with interfacial agent 92, further can efficiently improve cleaning Energy.

Its principle is as follows.That is, as shown in figure 11, usual interfacial agent 92 when reaching some concentration or more, live by interface Property agent 92 hydrophobic group assemble each other and micellization, form the agglutination body 93 of interfacial agent 92.The particle diameter of the agglutination body 93 For tens of nm.On the other hand, such as fine gas bubbles 91 of the particle diameter less than or equal to 500nm are accordingly changed into since its surface is negatively charged Hydrophobicity, therefore the hydrophobic group of interfacial agent 92 can be attracted.

Therefore, small containing particle diameter when being mixed into the cleaning agent of the agglutination body 93 of the interfacial agent 92 containing micellization When in the fine gas bubbles water of the fine gas bubbles 91 equal to 500nm, the energy stabilization state of agglutination body 93 is by fine gas bubbles 91 The hydrophobicity effect on surface is broken, and as shown in figure 12, agglutination body 93 ruptures, each molecule dispersion of interfacial agent 92.Then, divide Each molecule of scattered interfacial agent 92 is by the hydrophobic group of interfacial agent 92 with fine gas bubbles 91 with hydrophobic table Interaction between face, sorption is on the surface of fine gas bubbles 91.The interfacial agent 92 contained in cleaning solution as a result, is by sorption Complex 94 is formed on fine gas bubbles 91.

Moreover, as shown in figure 13, the floating due to fine gas bubbles 91 of complex 94 of interfacial agent 92 and fine gas bubbles 91 Power etc. is spread on a large scale in cleaning solution.Therefore, each molecule of interfacial agent 92, which for example touches, is attached to 1 table of tableware class The probability that dirty ingredient 95 on face waits greatly improves.Moreover, as shown in figure 14, when interfacial agent 92 and fine gas bubbles 91 When complex 94 is close to dirty ingredient 95, the energy stability between interfacial agent 92 and fine gas bubbles 91 is by dirty ingredient 95 The hydrophobic effect on surface break, cause fine gas bubbles 91 to deform and rupture.Therefore, each molecule of interfacial agent 92 point From simultaneously sorption on dirty ingredient 95, and dirty ingredient 95 is become easy by next collision in 91 zone of fracture of fine gas bubbles etc. Float and fall off from the surface of tableware class 1.

At this point, interfacial agent 92 enter due to the impact that fine gas bubbles 91 rupture and generate, dirty ingredient 95 with In gap between the surface of tableware class 1, promote the emulsification of dirty ingredient 95.Moreover, interfacial agent 92 is by absorbing simultaneously breast Dirty ingredient 95 is changed from the dirty ingredient 95 of the sur-face peeling of tableware class 1, thus to play cleaning ability.In this way, fine gas bubbles 91 Excite the cleaning ability of interfacial agent 92.

In addition, the cleaning agent used in dish cleaning machine 10 can also include sodium bicarbonate other than comprising interfacial agent Or citric acid etc..In addition, interfacial agent included in cleaning agent can be natural component and manually generated synthesis interface Any one in activating agent.Moreover, cleaning agent can also be any one shape in solid, liquid, body of powder.
