Embodiment 1
The backwater mechanism piping diagram of the steam cleaner of one embodiment as shown in Figure 1, the boiler 130 that steam cleaner comprises storage tank 110, the water pump 120 be communicated with water tank 110 and is communicated with water pump 120.Being communicated with water pump 120 with the pipeline of boiler 130 is inlet pipeline 140, arranges a backwater mechanism 150 between storage tank 110 and inlet pipeline 140.Backwater mechanism 150 comprises water return pipeline 151 and is arranged on water return pipeline 151 in order to control the valve 152 of water return pipeline 151 switch.
When steam cleaner is started working, the water in storage tank 110 enters boiler 130 via water pump 120 from inlet pipeline 140, forms steam ejection subsequently to reach application target in boiler 130.Valve 152 now on water return pipeline 151 is closed.When not needing ejection steam, open the valve 152 on water return pipeline 151, the residual water in boiler 130 and some vapor are oppositely discharged in water return pipeline 151 via inlet pipeline 140, be discharged in storage tank 110 recycle through water return pipeline 151.Therefore, this steam cleaner arranges backwater mechanism 150 between storage tank 110 and main water inlet tube road 140, the residual water and steam that discharge in boiler 130 when water pump 120 stopping is supplied water can be held, thus the remaining water and steam reduced in boiler 130 continues ejection, reduce the impact on result of use.
It should be noted that, the water return pipeline 151 of the present embodiment also can directly be connected with the boiler 130 of steam cleaner.When steam cleaner is started working, water in storage tank 110 enters boiler 130 via water pump 120 from inlet pipeline 140, when not needing ejection steam, the residual water discharged in boiler 130 and steam are directly entered storage tank 110 by water return pipeline 151, and need not enter water return pipeline 151 again via inlet pipeline 140.
Embodiment 2
As shown in Figure 2, steam cleaner comprises storage tank 210, the water pump 220 be communicated with storage tank 210 and boiler 230 to the backwater mechanism piping diagram of the steam cleaner of one embodiment.Pipeline between water pump 220 and boiler 230 is main water inlet tube road 240, arranges a backwater mechanism 250 between storage tank 210 and main water inlet tube road 240.Backwater mechanism 250 comprises water return pipeline 251 and is arranged in order to control the valve 252 of water return pipeline 251 switch on water return pipeline 251, in addition, arranges one and cushion cavity 253 between water return pipeline 251 and boiler 230.Buffering cavity 253 can be the pipeline of inner wall smooth, and the diameter of pipeline is greater than the diameter of main water inlet tube road and water return pipeline.Above-mentioned buffering cavity 253 is used for holding the water and steam oppositely discharged.When not needing ejection steam, open the valve 252 on water return pipeline 251, the residual water in boiler 230 and some vapor are first oppositely discharged in above-mentioned buffering cavity 253, with after to be discharged in storage tank 210 through water return pipeline 251 and to recycle.Arrange buffering cavity 253 can play better cushioning effect to when oppositely discharging from the residual water in boiler 230 and some vapor, prevent residual water and the pressure of some vapor to water return pipeline 251 excessive, affect the service life of steam cleaner.
In order to make above-mentioned buffering cavity 253 reach better backwater effect, a piston 300 can be set in the inside of this buffering cavity.Seal between this piston 300 energy and inwall of buffering cavity and arrange, and this piston 300 can along the axially-movable of buffering cavity.Meanwhile, this piston 300 is set to make the unidirectional check valve passed through of water and steam.As shown in Figure 3, piston 300 comprises gripper shoe 310 to the structural representation of piston 300, the first closure blocks 320 and the second closure blocks 330 be fixed in gripper shoe 310.Gripper shoe 310 distributes the aperture that water and steam can be made in a large number to pass through.First closure blocks 320 is fixedly connected with gripper shoe 310 respectively with one end of the second closure blocks 330, and the other end then docks the angle that formation is 150 ° inwardly, and joint forms the gap that water and steam can be made to pass through.First closure blocks 320 is arranged two the first boss 321 abutted against with the inwall of buffering cavity.Same, the second closure blocks 330 is arranged two the second boss 322 abutted against with the inwall of buffering cavity.
The motion state diagram of piston 300 during steam cleaner water inlet and the backwater of this backwater mechanism 250 is set as shown in Figure 4 to 7.When the water pump 220 of steam cleaner works, water filling enters main water inlet tube road 240, now closes the switch of valve 252 in water return pipeline 251, therefore the water in main water inlet tube road 240 enters buffering cavity 253 subsequently.Due to the percussion of current, the piston 300 being originally positioned at buffering cavity 253 inside left is made to be pushed to the inner right side position of buffering cavity 253.Buffering cavity 253 arranges the block 2531 that two are positioned at the distribution of upper and lower bilateral symmetry near one end, inside of boiler 230.When piston 300 moves to the inner right side of buffering cavity 253, namely stop moving forward after the first closure blocks 320 of piston 300 contacts with block 2531 with the second closure blocks 330.Block 2531 plays and stops piston 300 further toward the effect of boiler 230 1 lateral movement, can prevent piston 300 from snapping in pipeline like this.Because the first closure blocks 320 of piston 300 and the second closure blocks 330 form the structure with certain angle, therefore main water inlet tube road is injected in the aperture that the water now injected from water pump 220 can be distributed by the gripper shoe 310 of this piston 300 and the gap between the first closure blocks 320 and the second closure blocks 330, injects boiler 230 subsequently.
During steam cleaner backwater, the switch of 220 water inlets that switch off the pump, opens the switch of valve 252 in water return pipeline 251.Water in boiler 230 and some vapor are first oppositely discharged in main water inlet tube road 240, enter subsequently in buffering cavity 253 and promote piston 300 inverted running.During piston 300 inverted running, the water that can promote in buffering cavity 253 enters in storage tank via water return pipeline 251 and recycles.Because the first closure blocks 320 of piston 300 and the second closure blocks 330 exist angle structure, water and steam is not by the gap between the first closure blocks 320 and the second closure blocks 330 and the aperture be distributed in gripper shoe 310, therefore the water discharged from boiler 230 and some vapor will enter in this buffering cavity 253, and can not be directly released in water tank.Such buffering cavity 253 serves the cushioning effect from boiler in dispose procedure by water and some vapor, prevents high temperature water and steam from directly getting back to water tank, prevents from damaging water tank or causing user to be scalded by water tank.
The piston 300 cushioning cavity 253 inside in the present embodiment is not limited to this type of form, as long as water can pass through when can realize water inlet, can promote piston reverses direction and move when steam and water oppositely discharge in boiler.Piston 300 such as, can not arrange gripper shoe 310.Piston 300 can also be the check valve 420 arranging restriction orifice 410 as shown in Figure 8.Restriction orifice 410 is a kind of flow rate limiting devices, in order to limit the output of water pump, prevents into the too much situation of water.Check valve 420 comprises first end 421 and the second end 422.First end 421 is the inner bare terminal end for certain angle, and when current flow from left to right, first end 421 can be opened and current are passed through.But when current right-to-left flows, first end 421 is closure state, thus current not by., there is not the gap that water or steam can be made to pass through therebetween in the second end 422 and one end compact siro spinning technology of restriction orifice 410.Therefore, the check valve 420 arranging restriction orifice 410 can only make that water and steam is unidirectional to be passed through.Gripper shoe 310 on piston 300 can also be arranged to restriction orifice, as long as can play the effect identical with flow rate limiting device.
In addition, the gross area that piston can also distribute is less than the through hole of main water inlet tube road sectional area, and the number of through hole is one or more.When the number of through hole is multiple, the gross area of multiple through hole is less than the sectional area on main water inlet tube road.Through hole on piston is open state, and during water inlet, water can be entered in boiler by the through hole on piston.The gross area due to through hole is less than the sectional area on main water inlet tube road, therefore when the water and steam in boiler oppositely discharges can push belt through hole piston reverses direction motion, thus make water and steam be discharged into buffering cavity in.
Restriction orifice can limit flow of inlet water as a kind of flow rate limiting device, increases steam stable when using, and reduces and avoids the phenomenon that in steam, water content is too high occurs.Certainly, flow rate limiting device is not limited thereto kind of a form, and flow rate limiting device also can play for aperture sealing ring etc. the device regulating or limit flow of inlet water.Piston and flow rate limiting device can be separately positioned on and cushion cavity 253 inside, and do not need to be arranged to integrative-structure.
Embodiment 3
The backwater mechanism 350 that the steam cleaner of one embodiment comprises water pump 320, boiler 330 and is arranged between water pump 320 and boiler 330.Backwater mechanism 350 comprises water return pipeline 351, be arranged on water return pipeline 351 in order to the valve 352 that controls water return pipeline 351 switch and the buffering cavity 353 be arranged between water return pipeline and boiler.The pipeline that water pump 320 water supply enters boiler 330 is main water inlet tube road 340.Buffering cavity can be the pipeline of inner wall smooth, and the diameter of pipeline is greater than the diameter of main water inlet tube road and water return pipeline.Above-mentioned buffering cavity is used for holding the water and steam oppositely discharged.
The piston 500 be arranged in the present embodiment in buffering cavity 353 is closed, and namely piston 500 can not make water and steam pass through.Now, need to be used for making the unidirectional check valve 600 passed through of water from water pump with cushioning the secondary inlet pipeline 360 that communicates of cavity 353 and be arranged in inlet pipeline 360 with arranging between boiler 330 at buffering cavity 353.
In the present embodiment steam cleaner water inlet and backwater time backwater mechanism principle as shown in Figure 9 and Figure 10.When the water pump 320 of steam cleaner works, water filling enters main water inlet tube road 340, closes the switch of valve 352 in water return pipeline 351, and the water now in main water inlet tube road 340 enters buffering cavity 353 subsequently.Due to the percussion of current, the piston 500 of the inside left being originally positioned at buffering cavity 353 is pushed thus to the inner right side motion of buffering cavity.When piston 500 moves to the right side of the water inlet of the secondary inlet pipeline 360 be arranged on buffering cavity 353, current enter in time inlet pipeline 360, are then entered in boiler 330 by the check valve 600 be arranged on time inlet pipeline 360.Because piston 500 is the closed piston that current can not be made to pass through, therefore current cannot be entered in boiler 330 by piston 500.When piston 500 by water jet propulsion to buffering cavity 353 inside the rightmost side time and stop motion.
When not needing ejection steam, open the valve 352 on water return pipeline 351.Meanwhile, because the check valve 600 be arranged on time inlet pipeline 360 can only make that water is unidirectional to be passed through, the residual water therefore in boiler 330 and some vapor cannot by time inlet pipelines 360.Therefore the residual water in boiler 330 and some vapor are first oppositely discharged in above-mentioned buffering cavity 353, promote the counter motion of closed piston 500, and then the water remained in when promoting water inlet in buffering cavity 353 recycles via being discharged in storage tank in water return pipeline 351.The space of buffering cavity 353 is enough to hold from the residual water in boiler 330 and some vapor, and the remaining water and steam that can reduce in boiler continues ejection, reduces the impact on result of use.
In addition, the piston in buffering cavity is not limited to this type of form, also can only arrange a flow rate limiting device, such as restriction orifice or aperture sealing ring etc. in buffering cavity.This flow rate limiting device can limit flow of inlet water, increases steam stable when using, and reduces and avoids the phenomenon that in steam, water content is too high occurs.Certainly, the check valve being arranged in time inlet pipeline also can increase a flow rate limiting device be used for limiting flow of inlet water.Check valve and flow rate limiting device can be set to integral structure, also can individually be arranged in time inlet pipeline.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
