About the structure of sparge pipe 300, it is detailed below:
A kind of sparge pipe 300, comprising:
Tube body 310, the tube body 310 have water inlet end 311, hole for water spraying 330 are offered on its tube wall;
The position that the hole for water spraying 330 is corresponded on the sparge pipe 300 is formed with watering trough 320, the hole for water spraying 330 with The watering trough 320 is connected to, and the aperture of the hole for water spraying 330 is greater than the groove width of the watering trough 320.
Specifically, in the present embodiment, tube body 310 is in the form of a column setting, and specific structure is referred to right in above example The description of sparge pipe 300, emphasis describes the relationships such as the shape of sparge pipe 300 and watering trough 320, position herein.Wherein, hole for water spraying 330 run through the cell wall of tube body 310, and the water in tube body 310 is flowed out from hole for water spraying 330.
The shape of 310 cross section of tube body can have very much, such as round, ellipse, triangle polygon, in circle For shape setting.The shape of 330 cross section of hole for water spraying can have very much, such as round, ellipse, polygon, with setting in circle For shape.The cross-sectional shape of watering trough 320 can also have very much, such as U-shaped, trapezoidal, V-type and rectangle etc..In hydraulic pressure and In the case of hole for water spraying 330 is certain, the shape of watering trough 320 influences amount of water sprayed, and V-type water yield is minimum, trapezoidal middle water, rectangle Shi Shuiliang is maximum.The shape of the cross section of the watering trough 320 is arranged one in V-shaped, trapezoidal and rectangle, wherein trapezoidal Long bottom edge close to notch.The biggish one end that is open is corresponding with notch, by setting a variety of for the cross section of watering trough 320 Shape allows sparge pipe 300 to provide the water spray of different waters, to adapt to different operating conditions, to improve sparge pipe 300 Adaptability.The elongated setting of watering trough 320, watering trough 320 can extend along the length direction of tube body 310, with watering trough 320 Length direction it is parallel with the length direction of tube body 310 for.The slot bottom of watering trough 320 is connected to hole for water spraying 330, in sparge pipe In 300 course of work, the water in tube body 310 enters back into watering trough 320, and along watering trough 320 by hole for water spraying 330 Length direction diffusion and injection.In the course of injection of water, water flow is very big by a sectional area first again under the action of hydraulic pressure Hole for water spraying 330 after, (junction of hole for water spraying 330 and sink, area at this are less than hole for water spraying 330 after great constriction Area) it is spread in watering trough 320 again, flow process so, so that water flow forms the water flow of dispersion on an interface, produce Raw water flow is similar fan-shaped.Projection of the sector on tube body 310 is parallel with watering trough 320, in other words the extension side of watering trough 320 To this fan-shaped drift angle between 310 length direction of tube body being determined, if watering trough 320 is parallel to the length side of tube body 310 To, then fan-shaped chord length also in parallel with tube body 310.When be laid out on the length direction in sparge pipe 300 multiple hole for water sprayings 330 and spray After sink 320, the similar the same waterwall of water knife can be formed on some interface, so that the cleaning area of sparge pipe 300 obtains greatly The increase of width, in this way, all to achieve the effect that one is cleaned by all standing on the section of dish washer interior comprehensively.
In the present embodiment, by the setting of hole for water spraying 330 and watering trough 320, in the presence of hydraulic pressure, water flow is in hydraulic pressure Effect is lower to enter tube body 310, and flows in tube body 310, when by hole for water spraying 330, enters water spray in the presence of hydraulic pressure Hole 330, and entered in watering trough 320 after hole for water spraying 330;In the process, water flow first passes through larger-size water spray Hole 330 using the lesser watering trough 320 of width dimensions, and extends in the flute length direction of watering trough 320 and sprays, in this way, making Water flow self-spray sink 320 forms similar fan-shaped waterwall after spraying, planar cleaning is formed with the rotation of jet pipe, compared to existing The linear cleaning area having, significantly improves the cleaning effect of sparge pipe 300.
In order to further increase the cleaning effect of hole for water spraying 330 and watering trough 320, the groove width l of the watering trough 320 and institute Stating the ratio between the aperture Φ of hole for water spraying 330 is 0.18~0.25, by taking the value of l/ Φ is 0.2 as an example.Water flow is from hole for water spraying 330 It enters in watering trough 320, the variation of the hydraulic pressure of the groove width relationship in the aperture and watering trough 320 of hole for water spraying 330, from large area When hole for water spraying 330 enters watering trough 320, hydraulic pressure increases, and the proportionate relationship of the two is related to the reasonable release of water energy, influences to spray The distance and angle of jetting stream.When l/ Φ is too big, pressure difference is too small, and the distance and dynamics of injection water cannot get effective guarantee, It will be so that cleaning effect be undesirable;When l/ Φ is too small, groove width hinders the injection of water flow, and water and water speed are all affected, make It is undesirable to obtain cleaning effect.
In order to further increase the cleaning effect of hole for water spraying 330 and watering trough 320, the flute length L of the watering trough 320 and institute The ratio stated between the aperture Φ of hole for water spraying 330 is more than or equal to 2.5~3.5, for being more than or equal to 3.Water flow from Hole for water spraying 330 enters in watering trough 320, and the aperture of hole for water spraying 330 and the flute length of watering trough 320 are related to the variation of hydraulic pressure, When entering watering trough 320 from the hole for water spraying 330 of large area, hydraulic pressure increases, and water flow is spread along its length in the sink, water Pressure reduces, and the proportionate relationship of the two is related to the reasonable release of water energy, influences the angle of injection water.When L/ Φ is too small, slot It is long to be not enough to be diffused for the water that hole for water spraying 330 enters in watering trough 320, so that the angle of coverage of injection water reduces (fan-shaped central angle becomes smaller), is unfavorable for the hydro-peening of sparge pipe 300.
It is worth noting that the diameter of the water flow of watering trough 320, spray angle and distance and hole for water spraying 330 is certain It is positively correlated in range.The hole depth of hole for water spraying 330 has an impact to spray distance, and the hole of certain depth can be by lateral flow in pipe Energy be converted into the energy vertically flowed, be conducive to spray at a distance;Similarly, certain hole depth can increase the stream ejected Speed, to increase angle of flare.
When the cross-sectional shape of watering trough 320 is inverted trapezoidal, between the waist of the inverted trapezoidal of watering trough 320 and long bottom edge Slanted angle is β, is designed according to water, when the water of single watering trough 320 is bigger, β may be designed as it is bigger (i.e. section from Inverted trapezoidal develops into rectangle), when single-nozzle water operation is lesser, β should be designed as it is smaller (i.e. section from inverted trapezoidal to Up-side down triangle develops), in the present embodiment, β is 15~25 °, for 20 °.The in particular trough wall surface and notch of watering trough 320 Angle between the plane of place is β, and β is 15~25 °.
To meet different duty requirements, watering trough 320 of different shapes can be correspondingly arranged on same sparge pipe 300, It is specifically described below:
The quantity of the hole for water spraying 330 and watering trough 320 is multiple and is correspondingly arranged, the cross of multiple watering troughs 320 One or more in V-shaped, trapezoidal and rectangle is arranged in the shape in section.In the present embodiment, hole for water spraying 330 and watering trough 320 correspond, in some embodiments, can be with the corresponding multiple hole for water sprayings 330 of a watering trough 320, i.e. watering trough 320 is length Slot offers multiple hole for water sprayings 330 in the bottom of watering trough 320.The shape of 320 cross section of watering trough is same with sparge pipe Can be there are many form in 300, i.e., the angle where the trough wall surface of watering trough 320 and notch between plane can take a variety of values. Under some conditions, water needed for different location and backwash rate difference, at this point it is possible to pass through the shape for changing watering trough 320 Shape adjusts the angle β to realize.
In some embodiments, it is desirable to spraying zone carry out it is strong, in, it is weak etc. distinguish, for different cleaning degree Object to be cleaned is cleaned, and improves cleaning efficiency, the cross section setting of the watering trough 320 at 300 middle part of sparge pipe is in rectangle Perhaps trapezoidal or V-arrangement is arranged in the cross section of the watering trough 320 at trapezoidal 300 both ends of the sparge pipe;At this point, middle part is strong Cleaning area, and the both ends of sparge pipe 300 are middle cleaning area or weak cleaning area, in this way, be conducive to while efficiently cleaning not With the tableware to be cleaned of clean-up performance.
In some embodiments, due to the ejection with water flow, the water inlet end 311 of sparge pipe 300 and the water at driving end 312 Pressure is different, causes the water spray effect at both ends different, in order to enable the water spray effect of 300 different location of sparge pipe is uniform, close to institute 320 cross section of watering trough for stating 300 water inlet end 311 of sparge pipe is V-shaped, 320 cross section of watering trough at 300 middle part of sparge pipe Trapezoidal, 320 cross section of watering trough far from 300 water inlet end 311 of sparge pipe is in rectangle.In this way, making apart from water inlet end 311 farther away watering troughs 320 can also spray larger amount of water flow.
In order to adequately and reasonably utilize water energy, jeting effect is further increased, the hole for water spraying 330 includes inlet segment 331 With the changeover portion 332 extended from inlet segment 331 to the watering trough 320, the changeover portion 332 cuts 320 bottom of watering trough Portion extends to the notch of watering trough 320.Specifically, in the present embodiment, hole for water spraying 330 is by taking circular in cross-section is arranged as an example, mistake It crosses section 332 to extend to notch, cutting groove bottom, when the cross section of watering trough 320 is V-shaped or inverted trapezoidal is arranged, hole for water spraying 330 With the width of 320 junction of watering trough, greater than the width of 320 bottom of watering trough.By the setting of changeover portion 332, so that water spray The hole depth in hole 330 is moved to notch, the inlet area that water self-spray water hole 330 enters watering trough 320 is increased, so that water is in flowing In the process, it is unlikely to be largely lost, but by being entered in watering trough 320 from the position of groove sidewall, thus effectively Distance and drift angle that water flow is sprayed from sink greatly improved in the energy for remaining water flow, is conducive to improve sparge pipe 300 Cleaning efficiency.
In some embodiments, in order to further increase jeting effect, the aperture d at 332 top of changeover portion is less than The aperture D of the inlet segment 331.When water flow is in the inlet segment 331 Jing Guo major diameter, changeover portion 332 lesser by diameter, While being guided transition of water flow, hydraulic pressure increase, and are conducive to the distance and range that increase injection.
During transition, in order to avoid big friction and collision occur for water flow and hole wall and loss of energy, the mistake The inner wall of section 332 is crossed from the inlet segment 331 to the cell wall arc-shaped transition of the watering trough 320.In this way, working as water flow from inlet segment After 331 enter changeover portion 332, during entering watering trough 320 from changeover portion 332, water flow is by smooth guidance, favorably In reservation water energy.
In order to further improve the water spray effect of watering trough 320,332 top of changeover portion and the watering trough 320 The groove width of intersection is k, and aperture d is greater than or equal to 2 times of k.In the present embodiment, by the way that aperture d to be set greater than or wait In 2 times of groove width k, it ensure that hydraulic pressure in the variation entered in watering trough 320 from changeover portion 332, ensure that pressure difference, there is interests Water flow is more stable, reliable, efficient to enter watering trough 320, and extends and spray along the flute length of watering trough 320, there is interests Improve spray distance and spray angle.
