Description
Technical field
The present invention relates to the dish cleaning machine that a kind of inside has antiseptic.
Background technology
All the time, dish cleaning machine have with tableware put into rinse bath, wash successively after washing agent is dropped into rinse bath, rinsing, dry function.But, in existing dish cleaning machine, on the filter that the residue that washes out from tableware can set attached to bottom of rinse bath, perhaps remaining in the circulating path of rinse water, bacterium can breed in this residue and produce stink sometimes.In addition, clean running after, the sewage that contains residue etc. remains in the situation a lot (the following water that will remain in the ponding portion is called residual water) in the ponding portion of bottom of rinse bath and circulating path etc.Therefore, the residue of the being rich in nutrition composition in this residual water can promote the breeding of assorted bacterium and become antihygienic state, and can discharge foreign odor towards periphery, brings sticky feeling to the user.
In addition, in dish cleaning machine, generally can be equipped with and be used for heaters such as sheathed heater that water is heated, utilize this heater that recirculated water is heated when washing and during rinsing, thereby improve the cleaning performance of tableware or promote dry in the bottom.But, containing insoluble compositions such as calcium, magnesium, silicic acid in the running water, these materials will be as scale attached on the heater surface after in a single day becoming evaporation residue, will become floating state after these materials peel off and sneaks in the above-mentioned residual water.
Therefore, a kind of dish cleaning machine is proposed, carry photochemical catalyst on the part that constitutes dish cleaning machine, it is active to described photochemical catalyst irradiation ultraviolet radiation it to be produced, and utilizes the effect of photochemical catalyst that the bacterium that produces in the residual water is carried out sterilization (for example with reference to patent documentation 1).
With reference to Fig. 7 the antibacterial effect in the prior art example 1 to 4 is described.
In the dish cleaning machine of prior art example 1, in acrylic resin, sneak into 1% silver zeolite fine powder and be configured as bulk, about 30 these cake mass of gram are fixed near the small tableware box as antiseptic.Fig. 7 is illustrated in and carries out every day under the situation of a standard wash dishes, the variation that concentration of silver ions follows effluxion to produce after bringing into use from new placement antiseptic.At this moment, as silver ion stripping lentamente from silver zeolite of antimicrobial component.As shown in Figure 7, concentration of silver ions is very high when use has just begun, and antibacterial effect is better, but after the silver ion stripping of exposing on the acrylic resin surface, its concentration sharply descends.This is that the silver ion in the block structure can not use and waste because the silver ion in the block structure can not stripping.Therefore, through after about 20 days, concentration of silver ions drops to that to reach below the required concentration of general antibacterial effect be below the 1ppb, thereby can not bring into play sufficient antibacterial effect.
In the dish cleaning machine of prior art example 2, use the sparge pipe of the acrylic resin system of having sneaked into 1% left and right sides silver zeolite.In the prior art example 2, can make the direct stripping of silver ion in the residual water in the sparge pipe that mushroom is easy to breed most, this point is more superior than prior art example 1.As shown in Figure 7, prior art example 2 is also using when just having begun concentration of silver ions very high, and antibacterial effect is better.But after the silver ion stripping of exposing at resin surface, because the silver ion of resin inside is difficult to stripping, so the concentration of silver ions in the residual water descends, it is not good that antibacterial effect becomes.Therefore, through after about 3 months, concentration of silver ions drops to that to reach below the required concentration of general antibacterial effect be below the 1ppb.
In the dish cleaning machine of prior art example 3, silver zeolite is configured as the graininess of the about 2mm of diameter, and about 10 these materials of gram are placed on as antiseptic in the housing with water flowing, be set up in parallel with the small tableware box.Because zeolite is a porous plastid, surface area is very big, so compare with prior art example 1, can effectively use antiseptic, continues antibacterial effect.But as shown in Figure 7, the concentration of silver ion reduces gradually, and through after about 3 months, concentration of silver ions drops to that to reach below the required concentration of general antibacterial effect be below the 1ppb.In addition, use up even be configured as granular antiseptic silver ion, also residual with original form, so the user can not confirm not have antibacterial effect.
In the dish cleaning machine of prior art example 4, use the granular antiseptic that is configured as in the prior art example 3, but the antiseptic material does not use silver zeolite and uses silver-colored apatite.Also identical in prior art example 4 with prior art example 3, because the surface area of antiseptic is very big, so can effectively use antiseptic, improve the continuation of antibacterial effect, but through after about 2 months, concentration of silver ions drops to that to reach below the required concentration of general antibacterial effect be below the 1ppb.In addition, identical with prior art example 3 in prior art example 4, even the silver ion of silver-colored apatite uses up, it is also residual with original form to be configured as granular antiseptic, so the user can not confirm not have antibacterial effect.
Patent documentation 1: Japanese patent laid-open 10-276960 communique (Fig. 1)
In the dish cleaning machine of patent documentation 1 record, when making constituent part have the photochemical catalyst function, need on this constituent part, be provided for making the ultraviolet light source of its performance photochemical catalyst function.That is, the part that makes expectation obtain bactericidal effect except that needs has the photochemical catalyst function, and the light source of irradiation ultraviolet radiation also must be set, and exists to cause expensive shortcoming.And, ultraviolet light source need be configured in not with the rinse water position contacting on, can be easily and the position of changing at an easy rate so can not be provided in the user.Therefore, when light source cuts off or reaches service life, there is the shortcoming that expends a large amount of operations for replacing.
In the dish cleaning machine of prior art example 1 and 2 records of prior art example, when in the constituent part that constitutes by thermoplastic resin, sneaking into porous plastid of containing antimicrobial component etc. and making it have antibiotic property, have only the lip-deep antimicrobial component that contacts with residual water effective, compare seldom with the total amount of sneaking into, antimicrobial component just is consumed at short notice, is difficult to continue antibacterial effect.And,,, be connected with no antiseptic and all can't confirm so the user of dish cleaning machine can not confirm antiseptic stripping in rinse water owing in resin system constituent part, sneak into antimicrobial component.
In the dish cleaning machine of prior art example 3 and prior art example 4 records, when granular inorganic nature porous plastid being housed in when being provided with in the housing, though silver ion stripping effectively is difficult to keep for a long time antibacterial effect.In addition, though the user of dish cleaning machine can confirm to have antiseptic, can not confirm whether antibacterial effect is also continuing.
Moreover, in above-mentioned prior art document and prior art example 1 to 4, be difficult to remove scale attached on heater etc.
Summary of the invention

Fig. 4 is a side sectional view of the part of dish cleaning machine being cut open expression.As shown in the drawing, resinous small tableware box 8 is installed on lower floor's basket 7, be used to take in small tablewares such as chopsticks, spoon.Below this small tableware box 8 forms and all sides are all water through netted.The top opening of this small tableware box 8, inside is divided into a plurality of cells by demarcation strip.And, the antiseptic housing 28 as casing is installed in the front of this small tableware box 8.
With reference to Fig. 1 antiseptic housing 28 is described in detail.Fig. 1 (a) is a stereogram of observing antiseptic housing 28 from the top, front, and Fig. 1 (b) is the top stereogram of observing from lid 32 sides towards the below with antiseptic housing 28.This antiseptic housing 28 is containers of rectangular shape, is used to accommodate deliquescent gradually antiseptic 29, and the silver that this antiseptic 29 adds as antimicrobial component in calcium phosphate forms.Composition for antiseptic 29 will be narrated in the back.
And antiseptic housing 28 is used for the enterprising enforcement in a side that can be installed in small tableware box 8 and is formed wideer slightly than the width of small tableware box 8.On a face of antiseptic housing 28, be equipped with four clamping parts 30 with hook portion.These clamping parts 30 a pair ofly be configured near the upper end respectively and near the lower end relative on the equal height position, the left and right sides.Antiseptic housing 28 can utilize clamping part 30 relative small tableware box 8 dismounting, thus the antiseptic housing 28 that more renews can use up in antiseptic 29 strippings the time.
Another face of antiseptic housing 28 becomes can be by the lid 32 of hinge 31 rotations.In addition, also can utilize buckling piece (not shown) as required in case etc. formation close after then the structure of not opening.Like this, the user can not touch antiseptic 29, and such structure is better.
The maximum open of the 28a of this hole portion directly constitutes more little to antiseptic housing 28 belows more, at least antiseptic housing 28 bottom smaller or equal to 3mm.Thus, even when antiseptic 29 strippings are in rinse water or when antiseptic 29 fragmentations, can prevent as far as possible that also its fragment from falling in the rinse bath 6 from the 28a of hole portion.
Secondly antiseptic 29 is described.In this antiseptic 29, silver oxide accounts for 3%, and zinc oxide accounts for 27%, and cobalt oxide accounts for 1%, and calcium phosphate accounts for 69%.Effectiveness to each composition describes below.
Usually, have with SiO as dissolubility glass is known
2And B
2O
3For in the borosilicate acids glass of main component and the present embodiment with P
2O
5Phosphoric acid class glass for main component.In the present embodiment, antiseptic 29 is made of phosphoric acid class glass.Like this, owing to adopt phosphoric acid class glass, so except that having antibacterial effect, can prevent that also scale is attached on sheathed heater 19 and the thermistor 24.
Secondly scale is described.Long-term when using dish cleaning machine, evaporation residue compositions (scale) such as the calcium that contains in the running water, magnesium, silicic acid are separated out on the surface of sheathed heater 19 and thermistor 24 etc., and become big gradually.And, big if scale thickening becomes, then can cause the efficiency of heating surface of sheathed heater 19 to reduce, thermistor 24 can not carry out correct temperature measuring, therefore, the adding thermal control and might be able to not normally carry out of sheathed heater 19.
On the other hand, when this scale peels off, can bring unhygienic sense to the user attached in the rinse bath 6 and on the tableware.Especially the region that the evaporation residue composition that contains in running water is many, the amount of stockpiling of this scale is many, need clean continually.Thereby aqueous solutions of organic acids such as citric acid are put into case carry out the method that heat cycles makes the scale dissolving, removes as general employing of cleaning method, but this method need expend time in, operation, expense, it is unfavorable to bring to the user.
Phosphate composition (the P that is used for being dissolved in rinse water of this antiseptic 29
2O
5) be used to keep the transparency of glass, and be used for obtaining making silver ion slowly to be dissolved in the effect of rinse water.If its concentration is lower than 10 weight %, then can become does not have the transparency, and can not keep mechanical strength.On the other hand, if its concentration surpasses 80 weight %, then might cause mechanical strength to descend.Therefore, the content of phosphate composition is preferably 10～80 weight % of antiseptic 29 integral body, is preferably 30～70 weight %.Moreover, when this phosphate composition is dissolved in the water, carry out chelating (Ca with calcium and magnesium in the running water
2P
6O
18 2-, Mg
2P
6O
18 2-), thereby can improve the water-soluble of calcium component, prevent that calcium carbonate and calcium silicates from separating out as scale.
Wherein, silver oxide as the silver ion stripping, is brought into play antibacterial action in rinse water.And cobalt oxide is to add as antiseptic 29 being carried out painted its metal oxide that becomes blueness that makes, even if the few content about 1% also can make antiseptic 29 become bright-coloured blueness.
Particularly, the Ag that preferably contains 0.1～5 weight % as the composition of this antiseptic 29
2O, the phosphate composition of 10～90 weight % preferably is that main body is determined Ag with the antibacterial action
2The percentage by weight of O.Why be adjusted in this scope be because: if Ag
2The percentage by weight of O then can not obtain substantial antibacterial action less than 0.1 weight %, and on the other hand, if greater than 5 weight %, then antiseptic 29 is easy to because of light becomes brown, and manufacturing cost also improves.
In addition, also can contain zinc oxide about 0～50 weight % in addition with antibacterial action.This zinc oxide plays and prevents that this antiseptic 29 from becoming the effect of brown, though do not reach the such degree of silver ion, zinc ion also has the effect of removing the microorganism that touches and mushroom, inhibition breeding.But if its content surpasses 50 weight %, then gonorrhoea, variable color might appear in antiseptic 29, therefore preferably smaller or equal to 50 weight %.
Effect to present embodiment describes below.
At first, the content of standard cleaning running process (hereinafter referred to as standard process) is carried out simple declaration.
Not shown operating portion is operated the established standards process, and after indication running beginning, control loop 25 is carried out successively and is cleaned running, rinsing running, heating rinsing running, dry operating.In cleaning running and each rinsing running, carry out feed water valve 20 open actions of in rinse bath 6, supplying water successively, circulating pump 15 is moved the water in the rinse bath 6 from the washing action or the rinsing action of injection nozzle 12,12 ejections, the action that the water in the rinse bath 6 is discharged in circulating pump 15 actions.The water level (hereinafter referred to as cleaning water level) that cleans in running and each rinsing running is set at high water level (being equivalent to 3.5 liters), control loop 25 closes feed water valve 20 after going out water level rinse bath 6 in according to the input signal detection from the test section 23a of level sensor 23 and arriving the cleaning water level.In addition, reach this cleaning water level, also can not soak in the antiseptic housing 28 even supply water.
In cleaning running and heating rinsing running, control loop 25 adds thermal control according to the input signal of thermistor 24 to described sheathed heater 19, makes the rinse water temperature in the rinse bath 6 reach set point of temperature.In addition, in dry operating, 25 pairs of sheathed heaters 19 of control loop add thermal control, and make Air Blast fan 22 actions, thereby warm braw is circulated in rinse bath 6.
After cleaning running, rinsing running, heating rinsing running, though the rinse water of utilizing circulating pump 15 to discharge in the rinse bath 6 can not be discharged fully.Therefore, in sparge pipe 16, all the time the rinse water that is called residual water can residually be arranged.In this residual water owing to contain a large amount of nutritional labelings such as residue, so the environment that the formation mushroom is easy to breed.
In above-mentioned cleaning running, rinsing running, heating rinsing running, because rinse water and antiseptic housing 28 interior antiseptics 29 contact, so antiseptic 29 slowly dissolves in rinse water, its volume reduces gradually.Silver ion and the zinc ion stripping as the antimicrobial component that contain in this antiseptic 29 are carried out direct sterilization to the mushroom of breeding in described residual water, and silver ion and zinc ion make the tableware surface have antibacterial ability also thinly on the surface attached to tableware etc.
Adopt the foregoing description can obtain following effect.
With reference to Fig. 5 and Fig. 6 the effect of prior art example 1～4 and present embodiment is compared explanation.Fig. 5 is the time dependent chart of concentration of silver ions in the residual water of expression.Fig. 6 is the chart that present embodiment and prior art example 1 to 4 are compared.
Solid line among Fig. 5 is that about 6g (being equivalent to 3) antiseptic 29 is put into antiseptic housing 28, concentration of silver ions chart over time in the residual water of trying to achieve by experiment under the situation of carrying out " standard process " once a day.In addition, the dotted line among Fig. 5 (comprising dotted line, chain-dotted line) expression is used for the above-mentioned prior art example 1 to 4 that compares with present embodiment.Arrow in the chart is illustrated in the concentration of silver ions that obtains sufficient antibacterial effect in the residual water.Shown in this chart, when contacting with rinse water continuously, the prior art example promptly lost antibacterial effect at 2,3 months, and when adopting the formation of present embodiment, through still continuing to keep the valid density of silver ion after 42 months.
Because calcium phosphate is dissolved in the rinse water lentamente, and as the also stripping gradually of silver ion of antimicrobial component, so can suppress to breed in the residual water of mushroom in rinse bath 6.Thus, can prevent to produce stink and rotten, keep the health of dish cleaning machine.And, because the rinse water that contains this silver ion contacts with tableware is surperficial, thus silver ion attached on the tableware surface, thereby tableware itself also can have antibacterial action.
Calcium phosphate dissolves in rinse water very lentamente.Meanwhile, also stripping lentamente for a long time of silver ion.Therefore, as among Fig. 6 with shown in the contrast of prior art example 1 to 4, even the user does not change the maintenance of antiseptic 29 grades, also sustainable antibacterial effect.In addition, also can connect antiseptic housing 28 when needs are changed antiseptic 29 changes together.
Because antiseptic 29 is made of phosphoric acid class glass, thus can improve the water-soluble of calcium component, as among Fig. 6 with shown in the contrast of prior art example 1 to 4, can prevent that calcium carbonate and calcium silicates from separating out as scale.
Because the antiseptic housing 28 of accommodating antiseptic 29 is set on the small tableware box 8 that is installed on lower floor's basket 7, so in cleaning running and each rinsing running, rinse water contacts with antiseptic 29 when the force feed member is worked, when not working, do not contact, thereby can prevent that antiseptic 29 excessively is dissolved in the rinse water, prevent the silver ion stripping, but and then long term maintenance antibacterial effect.
In addition, antiseptic 29 is configured as disc-shape.Therefore, antiseptic 29 be can suppress and fragmentation and then the inside at rinse bath 6 at random caused with the inwall collision of antiseptic housing 28 owing to the hydraulic pressure of the rinse water of spraying from injection nozzle 12,12.
On antiseptic housing 28, form the hole 28a of portion, and constitute the inside that can observe antiseptic housing 28 as the limbers, thus as among Fig. 6 with shown in the contrast of prior art example 1 to 4, the user can be observed that antiseptic 29 uses up and the state of volume minimizing.
Owing to contain cobalt oxide as colouring agent in antiseptic 29, so antiseptic 29 can be colored as blueness, the user can observe the situation that exists of antiseptic 29 more easily from the logical via portion 28a in the outside of antiseptic housing 28 thus.In addition, the kind of colouring agent is so long as the harmless mineral-type pigment etc. arbitrarily that then can adopt of concentration.For example, also can obtain same effect even contain pigment such as cupric oxide and talcum.Especially carrying out with cupric oxide when painted, because copper ion itself also has antibacterial effect, so can obtain better antibacterial effect.
Because the maximum open of the 28a of hole portion directly constitutes the diameter smaller or equal to spray-hole 14, so, also can not stop up spray-hole 14 even contingency antiseptic 29 comes off and circulates with rinse water from the 28a of hole portion of antiseptic housing 28.
Because the opening of the 28a of hole portion of antiseptic housing 28 directly forms more little more downwards, even so just in case antiseptic 29 is broken in antiseptic housing 28, its fragment can not fall in the rinse bath 6 from the 28a of hole portion yet, and injection nozzle 12,12 and circulating pump 15 can be not damaged because of the collision of the fragment of antiseptic 29.
A narration and a demonstration embodiment in the accompanying drawings above the present invention is not limited to.
For example, antiseptic 29 can not be configured as disc-shape with antibiotic glass yet, uses but after tabular antibiotic glass broken into pieces the fragment more than a certain size is housed in the antiseptic housing 28.Because phosphoric acid class glass generally when fusion viscosity low and be difficult to be shaped, so as embodiment 1, be configured as the discoid cost that can increase, so this method of employing can reduce manufacturing cost.
Also can be by the size and the amount of accommodating in antiseptic housing 28 of suitable adjustment antiseptic 29, thus the concentration of silver ions in the residual water is increased.
As mentioned above, the present invention can do various distortion and implemented in the scope that does not break away from purport.
