The specific embodiment
Below, embodiments of the invention are described with reference to the accompanying drawings.
At first the structural order along Fig. 1～Figure 12 from device for dissolving detergent describes.
Detergent dissolution container 1 comprise from the substantial middle of the bottom wall portion 2 that forms the end upwards the motor of the tubular of protuberance keep tube 3 and be located at this motor keeping the seal member cylindraceous on tube 3 tops to keep tube 4.Detergent dissolution container 1, motor keep tube 3 and seal member to keep tube 4 usefulness synthetic resin to form one.
Motor keeps tube 3 to have the downside that extends setting in the outer bottom side of bottom wall portion 2 and keeps tube 3a.Keep tube 3a and motor to keep being provided with the positioning edge 5 that extends longitudinally setting in the tube 3 at this downside.
Drive motor 6 keeps the under shed of tube 3a to insert from downside, remains on motor and keeps in the tube 3.
As shown in Figure 6, in drive motor 6, becket 7 is reeled and is fixed on periphery.Two ends by becket 7 form slit 8.Because positioning edge 5 inserts in this slit 8 and embeds, so drive motor 6 positions, being held in simultaneously can spline.
Drive motor 6 has turning cylinder 9.On turning cylinder 9, supporting adapter ring 13 as shown in Figure 9 at front end.The annular knurl 13a that this adapter ring 13 has spline to use at outer circumferential side.The periphery that adapter ring 13 is gone into turning cylinder 9 to interior all side pressures is chimeric fixing.
The agitator arm 10 that is driven rotation by drive motor 6 is formed by synthetic resin.Agitator arm 10 has as shown in Figure 8: cover motor and keep the periphery of tube 3 and the cover 10a of portion cylindraceous that seal member keeps the periphery of tube 4; Cover the 10c of courtyard portion that seal member keeps tube 4 upsides; Be located on the 10c of courtyard portion, support the axle of the turning cylinder 9 of drive motor 6 to support shaft sleeve part 10b.
Axle supports shaft sleeve part 10b that the axle collar 15 of metal is arranged in periphery.The axle collar 15 supports shaft sleeve part 10b to form one with axle.
Adapter ring 13 is pressed into axle and supports in the axle supporting hole of shaft sleeve part 10b.Adapter ring 13 combines securely with the annular knurl 13a that axle supports shaft sleeve part 10b to use with spline.Owing on the periphery of axle support shaft sleeve part 10b, be provided with the axle collar 15 of metal, can expect that adapter ring 13 anti-brute forces are pressed into combination more firmly.
Stir rotation agitator arm 10 dissolving detergents.Because the viscosity of detergent dissolution liquid is strong, produce opposite power at drive motor 6., as previously mentioned, keep the engaging in the slit 8 of the positioning edge 5 of tube 3 and drive motor 6 by motor, drive motor 6 keeps not rotating.In addition, the direction of terminal 12 of the drive motor 6 of the lead 11 (representing in Fig. 7) be connected with power supply being installed also can be on the same direction of being everlasting.
Shaft sealing part 14 shown in Fig. 6 has circular, and is formed by rubber.This shaft sealing part 14 remains on seal member and keeps on the tube 4 as Fig. 1, shown in Figure 7.The periphery 14a of shaft sealing part 14 and seal member keep the inboard chimeric of tube 4, interior all 14b and the axle collar 15 sliding-contact of support shaft sleeve part 10b.
By with these shaft sealing part 14 sealings, can stop detergent dissolution liquid to flow to drive motor 6.
Because the axle collar 15 usefulness metals of interior all 14b sliding-contacts of shaft sealing part 14 form, can bear adapter ring 13 and support being pressed into of shaft sleeve part 10b, and can suppress external diameter and expand into big footpath to axle.Therefore, owing to changing, the sliding-contact state of the interior all 14b of shaft sealing part 14 and the axle collar 15 do not keep necessarily can keeping good sealing.
In addition, form the structure that detergent dissolution liquid is difficult to flow into the shaft sealing part side.
The a part of 10a that is agitator arm 10 usefulness cover covers the periphery of motor maintenance tube 3 and the periphery that seal member keeps tube 4, simultaneously, keeps the upside of tube 4 with the courtyard 10c of portion covering seal member.And, the labyrinth of formation close gap between agitator arm 10 and motor maintenance tube 3.
Therefore, even detergent dissolution liquid flows into agitator arm 10 and motor keeps between the tube 3, in the labyrinth structure, stop, wash the depths that the agent lysate can not flow into close clearance with the air layer that accumulates.Because the inflow of detergent dissolution liquid is stoped by the labyrinth structure of close gap,, detergent dissolution liquid can not take place usually like this so arriving the situation at shaft sealing part 14 places.
As Fig. 1, Fig. 6, shown in Figure 7, below detergent dissolution container 1, the engine casing (Eng Cas) 16 (double fixed part prevents to come off) that can insert the drive motor 6 that remains on motor maintenance tube 3 from following lateral inhibition is installed.This engine casing (Eng Cas) 16 is entrenched in downside and keeps the periphery of tube 3a to install, and it is fastening to screw togather many bolts 18 on the boss portion 17 below being located at detergent dissolution container 1.
At the downside of detergent dissolution container 1,, water jet cover 19 shown in Figure 6 is installed as Fig. 1, shown in Figure 7.Water jet cover 19 has a plurality of peristome 19a of the detergent dissolution liquid that generally scatters the dissolving of high concentration ground on the clothing class in sink (not illustrating).
Detergent dissolution container 1 and water jet cover 19 lump together by protuberance on the lower end periphery that is located at detergent dissolution container 1 21 and the chimeric of groove 22 that be located on the upper end periphery of water jet cover 19.Many wires 23 are clipped between the fitting portion of protuberance 21 and groove 22.By making the 23 energising heating of this metal wire, hot melt applies the detergent dissolution container 1 that formed by synthetic resin and the fitting portion of water jet cover 19.
Apply by this hot melt, the fitting portion of detergent dissolution container 1 and water jet cover 19 can keep watertight ground strong bonded.
Water filling parts 48 shown in Figure 7 are located at the top of detergent dissolution container 1 as shown in figure 10.These water filling parts 48 have the powder detergent that makes in the detergent dissolution container 1 to inject the dissolving water inlet 60 of dissolving water shown in Figure 11,12.Dissolving water inlet 60 is located at the front of water filling parts 48, has the shape of growing crosswise along horizontal expansion.
Be provided with the connector 61 of water injection pipe (not illustrating) in the feed intake rear side of parts 48 of water.This connector 61 is communicated with dissolving water inlet 60.Water filling parts 48 usefulness lump together two water filling parts sheets up and down and form.In that merging portion is the same with the water jet cover with above-mentioned detergent dissolution container up and down, apply with the metal wire hot melt.
49 mounting or dismounting of water filling parts 48 usefulness screws are mounted freely on the detergent dissolution container 1.Because the front of water filling parts 48 is outstanding the installation in detergent dissolution container 1, so can be toward inject dissolving water by the central authorities in the detergent dissolution container 1.Therefore, the dissolving water capacity is easily scattered in the powder detergent in detergent dissolution container 1.In addition, because 60 one-tenth shapes of growing crosswise of dissolving water inlet are injected dissolving water so can fall on a large scale, promote the dissolving of powder detergent easily.
It is desirable that the liquid level 26 of detergent dissolution liquid hangs down than shaft sealing part 14 as shown in Figure 7.Even this is because detergent dissolution liquid is injected into the depths of close clearance, can not reach shaft sealing part 14 yet.
When agitator arm 10 rotations, the liquid level of detergent dissolution liquid becomes bowl-shape liquid level 27.The central part liquid level step-down of detergent dissolution container 1 is stirring the situation that detergent dissolution liquid inflow shaft sealing part 14 can not take place when rotating.
Powder detergent contains the composition of the demineralized water that is called zeolite usually.This zeolite also has the effect of grinding agent, for example if rotate under the state of the shaft sealing part 14 of metal part 15 that enters agitator arm 10 and rubber system, its sealing wearing and tearing, leaks sometimes.
But, since before stir rotating than the lower liquid level 26 of shaft sealing part 14 stirring the further step-down of central part liquid level when rotating, so can suppress detergent dissolution liquid inflow shaft sealing part 14 fully.
In detergent dissolution container 1, on the opposition side position of water filling parts 48, be provided with gap 70.The peristome 19a of cover 19 is positioned at the below of this gap 70.Gap 70 is located at as shown in figure 13 than on the low height and position of water filling parts 48.During spilling water, flow to peristome 19a from gap 70.Cross water filling parts 48 spilling water does not take place.
In detergent dissolution container 1, on the side of gap 70 sides, be provided with peristome 52.Peristome 52 communicates with gap 70 and peristome 19a.Even peristome 52 freezes in the winter time, also can discharge spilling water etc. from peristome 52.
In detergent dissolution container 1, siphon mechanism 71 is as shown in figure 10 arranged.There are outer tube 72 and interior pipe 73 in siphon mechanism 71.If remain in the upper end that detergent dissolution container 1 interior water level surpasses interior pipe 73, the water in the detergent dissolution container 1 descends at interior pipe 73, flows to water jet cover 19.The decline of water table of detergent dissolution container 1 flows out to the atmosphere opening from the suction inlet of outer tube 72 bottoms.
The detergent dissolution liquid that generates in detergent dissolution container 1 is discharged to water jet cover 19 by siphon mechanism 71.
Promptly rotate water filling in detergent dissolution liquid generates afterwards by water filling parts 48 by the stirring of agitator arm 10.Water filling proceeds to the position that siphon mechanism 71 carries out siphonage, and the detergent dissolution liquid that generates by siphonage is discharged from.
Because the upper end of the interior pipe 73 of siphon mechanism 71 is lower than the height H of gap 70, so can before gap 70 drainings siphonage take place, the detergent dissolution liquid of generation is all discharged.
If siphon mechanism 71 is full of, the water level of detergent dissolution container 1 increases, owing to carrying out the spilling water selected from above-mentioned gap 70, the detergent dissolution liquid of generation can not crossed water filling parts 48 spilling waters or be overflowed by the rising wood of detergent dissolution container 1.
As mentioned above, embodiments of the invention do not need to comprise the connecting gear of synchronous band owing to directly driving agitator arm on the rotating shaft that is supported in drive motor.Can do one's utmost to reduce the quantity of using parts.
Because number of components is few, fee of material reduces certainly, and can shorten the time that assembling is finished significantly.
And then, do not need to comprise the connecting gear of synchronous band, become small-sized as a whole.Also can be contained on the small washing machine that washing capacity is 4kg and 5kg.
