The upper end portion that the internal diameter of stream 441 is big is fixed with iron core 450, thereby the upper end of plunger 440 is closed.
Elastic member 450 coats the outer circumferential face of plunger 440 in the bottom of protuberance 445.That is, the upper end of elastic member 460 and protuberance 445 butts, lower end and following exhaust port butt.This elastic member 460 carries out yielding support to top coupled columns plug 440, so that be fixed in the underpart of the iron core 450 sealing streams 423 of plunger 440 upper end portions.
Exhaust port is fixedly set in the bottom of the plunger 440 in the inner space 425, and the bottom of this exhaust port is outstanding to the outside of shell 410.And the parts in the inner space 425 of being disposed at of this exhaust port are formed with the O ring and lay portion 473, lay portion 473 at this O ring the O ring 475 that is used for sealing (sealing) is installed.
Be formed with the outflow road 471 that is communicated with stream 441 in the inside of exhaust port, and be connected with water pipe 217 to the lower end of the outstanding exhaust port in the outside of shell 410.
On the other hand, as shown in Figure 2, bucket 250 is placed in the bucket of front casing 211 and lays the 211a of portion.
Be provided with the lid 251 of tap hole (not shown) and switching tap hole in the lower end of bucket 250.Be provided with at lid 251 and carry out flexibly mounted switching film (not shown) downwards.Lid 251 connects current hand-hole 211b and is installed in water inflow portion 216, and the switching film that is installed on the lid 251 of water inflow portion 216 upwards is lifted and opens, and thus, bucket 250 inner water flow out through open switching film.
Be provided with the groove 252 that combines with elastic hook 212 in the upper end of bucket 250, and be provided with the handle 253 of groove shape, so that from shell 210 dismounting buckets 250 in the bi-side of bucket 250.
As shown in Figure 2, base assembly 300 is made up of through assembling upper body 310 and chassis 350, and wherein, upper body 310 is disposed at top and can be connected with shell 210 rotatably, and chassis 350 is disposed at the bottom.
350 are formed with a plurality of steam jetting hole (not shown) on the chassis, and form steam jetting hole 351 the both sides at position, the pad facies posterior hepatis that is provided with the Velcro fabric is so that attachment pad etc.
Inside on upper body that assembles 310 and chassis 350 is provided with the supply of accepting water and the steam generator 330 that makes steam generation.
Steam generator 330 is connected with the other end of water pipe 217, and an end of this water pipe 217 is connected with water inflow portion 216.In addition, steam generator 330 is connected with the steam (vapor) outlet pipe 219 of exhaust steam, and the end of steam (vapor) outlet pipe 219 is towards the chassis 350, thereby is convenient to the steam jetting hole exhaust steam that is formed at chassis 350.
Below, the operating state of the steam cleaner of the solenoid valve of the present invention of formation describes to being suitable for as described above.
When the user in order bucket 250 to be poured water and to grasp handle 253 when the place ahead of steam cleaner pulls, elastic hook breaks away from from groove 252, separates bucket 250 thereby can be convenient to lay the 211a of portion from bucket.
User's uncap 251 is after bucket 250 is filled water; The handle 253 that grasps bucket 250 rearward rotates bucket 250 so that lid connects the state of current hand-hole 211b; Then the sound elastic hook along with click is snapped fit onto groove 252, lays the 211a of portion thereby bucket 250 easily is placed to bucket.
On the other hand, bucket 250 inner water flow out through open switching film, and supply to water pipe 217.
When the user pushes power knob 211c; Power supply is applied in; Steam generator 330 is heated; When the heater in the steam generator 330 rose to more than 160 ℃, solenoid valve 218 was switched on and opens, thus solenoid valve 218 so that water in one minute, move through the mode of the amount about 200cc.
Like this, through the action of solenoid valve 218, in one minute, there is roughly the ground of the amount about 200cc water flow in the steam generators 380, and discharges through steam (vapor) outlet pipe 219 along water pipe 217.
Steam through steam (vapor) outlet pipe 219 is discharged sprays to the steam jetting hole on chassis 350.
Below, the action of solenoid valve involved in the present invention 400 is described.
As shown in Figure 6, the plunger 440 under the state that does not apply power supply in the inner space 425 to above by elastic member 460 yielding supports, and iron core 450 shutoff of being fixed in plunger 440 upper ends flow into road 423, therefore can block flowing along the water that flows into road 423.
When applying power supply through electric wire, as shown in Figure 7, coil 423 is applied in electric current and forms magnetic force, and plunger 440 moves downwards through this magnetic force.
Thus; 450 pairs of sealed up inflows of iron core road 423 of being fixed in plunger 440 upper ends is opened; Water is through flowing into 423 inflow inner spaces 425, road, and the water in the inner space 425 moves along stream 441 through ostium 443, finally discharges from water pipe 217 through flowing out road 471.
Above-mentioned solenoid valve 440 is simple in structure, can reduce number of components, thus can reduce operating cost, and can simplify assembling procedure and enhance productivity.In addition, can reduce the misoperation of solenoid valve 400 significantly.
As stated, describe the present invention according to embodiment and accompanying drawing, but the present invention is not limited thereto, those of ordinary skill in the art obviously can carry out various modifications and distortion in the impartial scope of technological thought of the present invention and claims.
