In this case, the inflow entrance 25 of water first from the bottom 21a being formed in filtrating equipment 13 flows in filtering box 21.Inflow entrance 25 is not adsorbed on bathtub 10 bottom surface, water flows into swimmingly from the gap between the foot 27 that compartment projection is arranged, and be discharged from air tap hole 26 because the air in filtering box 21 is such as indicated by the dashed arrow in fig. 1, the current thus in this filtering box 21 move rapidly.Like this, the pumping function brought by pump body 12 plays water sorption effectively, and can not suck air.But, when the water level in bathtub 10 arrives air tap hole 26 place, will outside air be sucked, and normal pumping function cannot be maintained, therefore, need as residue water to retain the water level arrived till air tap hole 26 place.
Below, according to normal pumping function, to in pump-unit 2, mainly the current of filtrating equipment 13 side be described, as shown in solid arrow in Fig. 1, the water flowed in filtering box 21 from the inflow entrance 25 of filtrating equipment 13 bottom passes filter material 23 and passes multiple water ports 30 of core components 22, and then with in the mode inflow pump housing 14 sucked by the water sucking mouth 17 of pump body 12 side.The water that flows into this pump body 12 side is all filtered by filter material 23.Namely, effectively can remove the trickle impurity etc. be mixed in water, in addition, when absorbing water from other the water storage source such as water storage tank, also the impurity that iron rust (red rust) etc. is trickle can effectively be removed, therefore, as so-called filtrating equipment 13, give play to filtering function originally, the water filtering out the cleaning after impurity can be supplied to pump body 12 side and then be supplied to washing machine 1 side.
In addition, although filter material 23 covers the whole circumferential lateral surface of core components 22, but, half area due to this core components 22 is formed as the tubular with the end (being equivalent to accommodation section 31) of the aporate not arranging water port 30, therefore, the water of filter material 23 Lower Half corresponded by situation compared with the first half (corresponding to water port 30), although well not talkative, water saturates filter material 23 thus flow into the inside of core components 22.Therefore, when the impurity that the first half by filter material 23 is caught makes clogging state development worsen and causes water permeability to reduce, the circulation and the filtration that are positioned at the water of Lower Half are more effective, can long term maintenance filtering function originally as filtrating equipment 13.
On the other hand, for the current around above-mentioned core components 22, because the antimicrobial agent 24 in this core components 22 is in the accommodation section 31 of aporate with the surrounding be housed in except upper surface under being placed on the state in receiver 33, therefore, the situation of directly bearing current is from the side less.But in the stage that filtrating equipment 13 is arranged in bathtub 10, water flows into accommodation section 31 by filter material 23 and core components 22, therefore, the antimicrobial agent 24 in receiver 33 is also in the state be immersed in water naturally.Along with the driving of pump body 12, the water in this accommodation section 31 is in the state that the aqueous phase that flows with the top side in this accommodation section 31 and receiver 33 contacts, and therefore, flows out upward gradually from accommodation section 31, thus replaces with new water.
In addition, in the water supply stroke of driven pump body 12, the antimicrobial agent 24 of slow dissolubility is in the state be immersed in water, thus leachable antimicrobial component.But, in the water supply stroke shorter with the time of contact of water, be difficult to the antibacterial effect by regulating solubility to obtain expectation, even if passable, improve deliquescent antimicrobial agent and also have following difficult point: make owing to consuming fast the maintenance management of supply again etc. become trouble, and mold resistance also significantly changes accordingly with the water yield and water supply time etc., not easily obtain antibacterial effect etc. that is stable, that expect.
Therefore, such as in such a way solubility is regulated to the antimicrobial agent 24 in present embodiment: after terminating laundry operation first, antimicrobial agent 24 is remained the state (detailed content will be described hereinafter) be soaked in water, until the water supply action of laundry operation can the antimicrobial component of stripping valid density next time.Namely, the constituent with following slow dissolubility is arranged to: supposing that usual every day all washs, the antibacterial effect of expectation can be obtained when carrying out the laundry operation of next day (next time).
Therefore, as the antimicrobial agent 24 of the slow dissolubility of present embodiment, by regulating as the proportion of the phosphate composition of the main component of phosphate glass, and regulating the stripping degree as the silver ion of antimicrobial component, can obtain and preferably slightly have an antimicrobial agent 24 of slightly solubility.Therefore, in actual use, although once washing operation comprises the water supply stroke of rinsing interior execution about 2 ~ 4 times, but in the water supply stroke of short time of laundry operation first, few with the time of contact of water, can only a small amount of antimicrobial component of stripping, effective antibacterial effect can not be given to washing.
Therefore, in order to make the antimicrobial component of above-mentioned antimicrobial agent 24 stripping valid density, the means this antimicrobial agent 24 being remained the state be soaked in water are described.Such as, after terminating laundry operation first, the pump-unit 2 under the use form shown in Fig. 2 is taken out from still remaining to have the bathtub 10 of water.Now, pump-unit 2 remained on the use form of longitudinal state and pick up, namely maintaining vertical vertical state.Like this, most water in pump-unit 2 (pump body 12 and filtrating equipment 13) towards with shown in the solid arrow of Fig. 1, driven pump body 12 time the roughly contrary direction of water (flow) direction flow, and finally flow out to outside from the air tap hole 26 of filtering box 21 and the inflow entrance 25 of bottom.
But, the accommodation section 31 of core components 22 Lower Half be formed as playing as water storage part function, aporate have bottom tube-like, therefore, the water of the established amount in this accommodation section 31 can not flow out and can left behind.Namely, under the antimicrobial agent 24 in receiver 33 is soaked in the state in the water of established amount, pump-unit 2 is fetched to outside.Then, keeping this vertical vertical state constant mode to be accommodated shown in figure 2 by pump-unit 2, be arranged on washing machine 1 pump accommodation section 11 in.Pump-unit 2 entirety is accommodated can fill the mode of getting in this pump accommodation section 11, and is kept being fixed as vertical vertical state by this pump-unit 2.
Like this, obtained with the state be soaked in the water of established amount the time effectively contacted with water by the antimicrobial agent 24 of the slow dissolubility taken care of for a long time, and the antimicrobial component of stripping valid density, until the state that reaches capacity.Therefore, on carrying out once laundry operation time, pump-unit 2 is taken out from pump accommodation section 11, put it in bathtub 10 to keep the constant mode of its vertical vertical state, completing the longitudinal state etc. of being set to, after the preparatory work of the pump-unit 2 that is used for operating as described above, perform the operation of washing machine 1.
Its result, in the water supply stroke of supply scouring water, water is subject to pumping action in the same manner as aforementioned and towards the direction flowing shown in the solid arrow in Fig. 1, the water being eliminated impurity by filter material 23 is supplied to washing machine 1 via water supply hose 9 etc.And, different from above-mentioned washing first, a certain amount of mixing water of the necessary antimicrobial component of stripping is stored in accommodation section 31, therefore, by the scouring water containing this antimicrobial component are supplied in washing tank, and make this antimicrobial component be attached on washing in the mode of impregnation, can give to washed washing the antibacterial effect expected.
Thus, because do not need to make antimicrobial agent 24 dissolve as early as possible, therefore, it is possible to use for a long time, and can reduce disassemble filtrating equipment 13 come supply antimicrobial agent 24 supply operation.In addition, that can carry out this filtrating equipment 13 simply disassembles assembling, such as, in order to be separated with pump body 12 side, filtering box 21 and core components 22 all have employed the mode screwed togather, therefore, it is possible to easily remove this bonding state by manual operations, and can easily assemble.
When needs carry out this disassemble assembling, the degree of fouling (clogging state) of filter material 23 is confirmed from the outside of transparent filtering box 21, such as when needs change filter material 23, only by filtering box 21 from the state of disassembling that pump body 12 side spins off, just can change simply, and especially select the cloth of white color system as filter material 23, degree of fouling can be confirmed clearly further thus, without the need to carrying out disassembling replacing period that just easily can differentiate filter material 23 etc., very convenient.
On the other hand, when needing to re-start supply in the consumption due to antimicrobial agent 24, although need to disassemble assembling to filtrating equipment 13 entirety, because core components 22 itself is also have employed the package assembly screwed togather, thus can be disassembled by simple manual operations.And, as shown in the embodiment, antimicrobial agent 24 is formed as the boxlike form be housed in receiver 33, thus process is convenient to when supply, further, make if core components 22 is also transparent resin, then can carry out visual confirmation from the outside of this core components 22 through receiver 33, can be confirmed whether in advance need supply antimicrobial agent 24 and then be confirmed whether that needs decompose, very convenient.
As described above, by the pump-unit 2 with filtrating equipment 13 being applied to the mode of execution of washing machine 1, following effect can be expected.
The pump body 12 had by pump-unit 2, can easily from water storage sources such as bathtub 10 or other water storage tanks to washing machine 1 for feedwater, using as scouring water.In this case, filtered by the filter material 23 of the filtrating equipment 13 being arranged on the suction side of pump body 12 bottom, can supply eliminating the clean water of impurity in water as scouring water, particularly for impurity fine using water storage tank etc. as the iron rust (red rust) easily produced during water storage source etc., by forming filter material 23 with nonwovens, can this impurity be removed effectively and form clean water, the dirty variable color of washing can be prevented.
