Detailed description of the invention
Below, embodiment the present invention specialized is described.
As shown in Figure 1 and Figure 4, the shower nozzle 10 of present embodiment possesses nozzle body 13, and nozzle body 13 has handle portion 11, and is provided with the stream 12 making current logical in the inside of nozzle body 13.The leading section of described nozzle body 13 is provided with the discharge opening 14 of tubular.Nozzle body 13 is provided with button 15, and by pressing this button 15 to a direction, described stream 12 is cut off, and to reverse direction pressing button 15, stream 12 is open.Therefore, by this button 15, shower nozzle 10 can switch in spue state and spuing between halted state of water.Described discharge opening 14 is formed the passage 16 be communicated with described stream 12.The front end of shower nozzle 10 is provided with surface elements 17.The central part of described surface elements 17 is formed with nozzle 18, and externally spue when this nozzle 18 is for cleaning wall etc. water.
Described passage 16 possesses: the part 1 16a being positioned at discharge opening 14 center; Be positioned at the part 2 16b of part 1 16a periphery; And be positioned at the 3rd part 16c of part 2 16b periphery.So by switching mechanism 19, any one making among the 1st ~ 3rd part 16a, 16b, 16c is communicated with described stream 12 in the mode of selecting.By carrying out rotating operation to the ring 20 that the position between the periphery of surface elements 17 and nozzle body 13 is rotatably arranged, thus described switching mechanism 19 is carried out switching action.Knob 21 is for carrying out rotating operation to ring 20.
That is, switching mechanism 19 comprises: spherical spool 23, is incorporated in receiving room 22; Helical spring 24, pushes away this spool 23 to valve closing (left of Fig. 1) direction bullet; And the switching part 25 to be integrally formed with described ring 20.So when ring 20 is by rotation, switching part 25 is rotated.By the rotation of this switching part 25, the corresponding relation between spool 23 and not shown multiple valve openings is switched, and any one in the 1st ~ 3rd part 16a, 16b, 16c is connected with stream 12.
Described discharge opening 14 perisporium 14a and the bottom of part 1 16a is formed with introducing port 37, introducing port 37 as introduce from stream 12 water communication channel use.Import to the water in part 1 16a from this introducing port 37 to flow out to the direction of described nozzle 18, i.e. the direction x that spues.Now, in order to carry out rectification to this water, the internal diameter r of part 1 16a is set to 1: 1.21 ~ 1: 3.0 with the ratio from the distance L of described introducing port 37 to nozzle 18.When distance L is less than 1.21 with the ratio of internal diameter r, the curtailment of part 1 16a.Therefore, even if there is filter screen 38 described later, be also difficult to the rectification realizing water in part 1 16a, from the water diffusion that nozzle 18 spues.Its result, can not obtain the current 32a of straight shape (Straight).On the other hand, when distance L is greater than 3.0 with the ratio of internal diameter r, the length of discharge opening 14 is long, and shower nozzle 10 becomes large shape, and the usability of shower nozzle 10 is deteriorated.
In addition, on part 1 16a, between the front end and surface elements 17 of the perisporium 14a of discharge opening 14, be provided with 2 filter screens (strainer) 38 as rectification part.As shown in Figure 9, described each filter screen 38 is formed by stainless steel, is made up of the net 38b inside circular ring 38a and its.The ring 38a of 2 filter screens 38 is clamped between the perisporium 14a of discharge opening 14 and surface elements 17.The wire diameter of the stainless steel wire that net 38b uses is 0.1 ~ 0.3mm, such as 0.2mm.This net 38b forms by weaving at longitudinal direction and the multiple lines that transversely extend.In addition, 2 throw the net and between 38b, be provided with the interval of 1 ~ 0.5mm.
Each filter screen 38 described for the water that will import to from introducing port 37 in described part 1 16a towards the direction x rectification that spues.In order to realize good rectification effect while suppressing the impedance produced current, when the hydraulic pressure in discharge opening 14 is 0.025 ~ 0.075MPa (megapascal (MPa)), if the wire diameter of net 38b is in the scope of 0.1 ~ 0.3mm, preferably each filter screen 38 has 30 ~ 100 orders, such as 70 object meshes.In addition, order is the unit of the mesh quantity represented in every 1 inch of (25.4mm) area.Under mesh is less than 30 object situations, mesh is excessive, fully can not obtain the rectification effect of water.At mesh more than in 100 object situations, mesh is meticulous, and the impedance produced current is excessive, its result, and discharge-amount reduces.In addition, although even if filter screen 38 only has one, also effectively rectification effect can be realized, but by arranging 2 with upper filter screen, effect can be improved further.When filter screen 38 is multiple, the position relationship of mesh impacts rectification effect hardly.That is, spuing on direction, no matter mesh to stagger or corresponding, and rectification effect has no difference.In addition, although the size at interval between multiple filter screens 38 brings impact to rectification effect hardly, however preferably should between be interposed between more than 0.5mm.
As shown in Figures 1 and 3, described nozzle 18 is arranged on protuberance 26, this protuberance is given prominence to toward the front in the center of surface elements 17, and described nozzle 18 is made up of the 2nd recess 28 of the 1st recess 27 of the spherically shape inside surface elements 17 and the channel-shaped of growing crosswise in outside.Described 2nd recess 28 has upper surface 28a and lower surface 28b in the mode expanded to open side from inside portion.2nd recess 28 entreats position to be communicated with described 1st recess 27 wherein.Therefore, the water reaching the 1st recess 27 is that membranaceous state spues with lateral magnification in the 2nd recess 28.As shown in Figure 5, described 2nd recess 28 upper surface 28a with between lower surface 28b and the mode above being in the front side in the direction that spues of water relative to the face 26a orthogonal with the front end face of described protuberance 26 with the face 28e that these faces 28a, 28b are separated by equidistant position that is positioned at tilt.In this embodiment, face 28e is 20 degree relative to the angle θ of face 26a.Therefore, as shown in double dot dash line in Fig. 1, when the face 26a orthogonal with the front end face of described protuberance 26 is in level, the water sprayed from nozzle 18 spues towards oblique upper.
That is, the water from described part 1 16a arrives nozzle 18, is spued obliquely upward from the 1st recess 27 by the 2nd recess 28 with straight shape in fan-shaped membranaceous form (see Fig. 1 and Fig. 7).Then, the current that spue are subject to air impedance, form water droplet, become the form (leftward position see Fig. 1) of diffusion type.The guttation form of this diffusion type as shown in Figure 8, is the oval shape of growing crosswise when being formed as watching from front.And, by the current 32a of straight shape, can effectively clean narrow positions such as the seam 35 in bathroom 33, corners 36; By the current 32b of diffusion type, can effectively clean broad positions such as the walls 34 in bathroom 33.
As shown in FIG. 1 to 3, ratio nozzle 18 cyclic position in the outer part of described surface elements 17 runs through and has multiple hole 43, by the thin current of multiply spued from this some holes 43, form so-called strong shower (hardshower).The ratio hole 43 of surface elements 17 cyclic position in the outer part runs through and is provided with multiple hole 44, by the vaporific guttation spued from this some holes 44, form so-called weak shower (softshower).Then, by operating the knob 21 of described switching mechanism 19, described stream 12 is connected with any one of the 1st ~ 3rd part 16a ~ 16c of described discharge opening 14, from the current 32a of straight shape, strong shower and weak shower optional one.
As shown in Figure 4, the upper end of surface elements 17 is provided with indicateing arm 45, indicateing arm 45 is for confirming the turned position of ring 20, and be provided with on ring 20 and represent from the mark of the guttation form of nozzle 18, mark comprise represent straight current 32a mark 46, represent the mark 47 of strong shower and represent the mark 48 of weak shower.So, when knob 21 is positioned at foot, the mark 46 of straight current 32a is opposed with indicateing arm 45, when knob 21 is rotated predetermined angular from this position to the counter clockwise direction of Fig. 3, the mark 47 of strong shower is opposed with indicateing arm 45, by clockwise direction from knob 21 to Fig. 3 rotate predetermined angular time, the mark 48 of weak shower is opposed with indicateing arm 45.And described switching mechanism 19 carries out action according to the position of mark 46,47,48, as mentioned above, from the current 32a of straight shape, strong shower and weak shower, any one is selected.
Then, the function of the shower nozzle 10 of present embodiment is described.
First, as shown in Figure 7, when using shower nozzle 10, the handle portion 11 of user to nozzle body 13 holds, and the ring 20 of effects on surface parts 17 carries out rotating operation, is set as representing that the mark 46 ~ 48 of wishing guttation form is opposed with indicateing arm 45.Such as, opposed with indicateing arm 45 by being set as the mark 47 of strong shower, thus health or cleaning hair can be cleaned with strong shower.
When cleaning positions such as the wall 34 in bathroom 33, seam 35, corners 36, making described ring 20 be positioned at foot, being set to that the mark 46 of straight current 32a is opposed with indicateing arm 45.As shown in Figure 1, in this condition, the water from part 1 16a flows from the 1st recess 27 of nozzle 18 to the 2nd recess 28.Now, overlapped 2 filter screens 38 between discharge opening 14 and nozzle 18, so the water imported in part 1 16a from introducing port 37 is rectified by filter screen 38.In this case, because the net 38b of filter screen 38 is consisted of braided metal line, so water unrolls and forms turbulent flow around each line, by the mixing effect of this turbulent flow, whole net 38b is rectified, and produces pressure differential in the front and back of filter screen 38 hardly.And, be set to 1.21 ~ 3.0 from the distance L of nozzle 18 to introducing port 37 with the ratio of the internal diameter r of part 1 16a, so the water imported in part 1 16a from introducing port 37 is suitably rectified along with towards nozzle 18.Therefore, the water spued from nozzle 18 forms the form of straight shape, and its front is diffusion mode.
Therefore, as shown in Figure 7, make shower nozzle 10 near the seam 35 in bathroom 33, can be undertaken concentrating cleaning by the narrow such as current 32a abutment joint 35, corner 36 of straight shape.Shower nozzle 10 is left from seam 35 or corner 36, and as shown in Figure 8, the broad wall 34 that can clean bathroom 33 efficiently by the current 32b of diffusion type cleans.
Sum up the effect recorded and can be played by above embodiment below.
(1) in shower nozzle 10 in embodiments, when being 1 with internal diameter r, 1.21 ~ 3.0 are set as with the ratio of the internal diameter r of the part 1 16a of discharge opening 14, so part 1 16a is formed as the shape being enough to the current of its inside be carried out to rectification from the distance L of introducing port 37 to nozzle 18.And, be configured with the filter screen 38 as rectification part at the upstream side of nozzle 18.Therefore, the water importing to part 1 16a from introducing port 37 is rectified, and to spuing, direction x flows out.And the water spued from nozzle 18 demonstrates and is rectified into straight membranaceous guttation form from nozzle 18, demonstrates diffuse into radial guttation form in its front end.
Thus, according to the shower nozzle 10 of embodiment, the current 32a of straight shape can be utilized effectively to clean the narrow positions in bathroom 33, and utilize the current 32b of diffusion type effectively to clean broad position.
(2) rectification part is made up of filter screen 38, the stainless steel wire that filter screen 38 is 0.1 ~ 0.3mm by wire diameter weaves and forms, there are 30 ~ 100 object meshes, so while suppressing water by circulation impedance during filter screen 38, effectively rectification can be carried out from discharge opening 14 to the direction x that spues.
(3) rectification part is made up of 2 (multiple) filter screens 38, so when water is by first filter screen 38, by the direction x rectification that spues to nozzle 18, when the water obtaining rectification is by second filter screen 38, further by the direction x rectification that spues to nozzle 18.Therefore, it is possible to improve the rectification effect of water further.
(4) head of above people from direction or the mode of health water supply use shower nozzle 10 mostly.Therefore, as shown in Figure 6, shower nozzle 10 is formed as in an erect condition that its upper side is downward.Therefore, surface elements 17 is also configured to downward, and the hole 43,44 of strong shower and weak shower refers to oliquely downward.But the water spued from nozzle 18 is used to the cleaning of wall etc.Therefore, pointing to the formation in hole 43,44 identical directions at nozzle 18, when cleaning wall, especially when the top of cleaning wall, needing shower nozzle 10 to remain upward.In this case, bring larger burden to upper arm or wrist, be not easy to carry out washing and cleaning operation.In contrast, the nozzle 18 of present embodiment is configured to spue obliquely upward water.Therefore, the demand remained by shower nozzle 10 upward reduces, and easily can carry out washing and cleaning operation.
[embodiment 1]
Then, about the shower nozzle 10 of above-mentioned embodiment, the relation between the internal diameter r to part 1 16a and the distance L from introducing port 37 to nozzle 18, carries out various change to condition, tests.
That is, make part 1 16a internal diameter r and from the distance L of introducing port 37 to nozzle 18 change as shown in table 1.Then, the running water giving predetermined pressure is supplied from stream 12 to nozzle 18.And, with following criterion visual valuation guttation form.By their result for table 1.In addition, in this case, the direction of growing crosswise of the 2nd recess 28 of nozzle 18, namely, side-to-side dimensions (left and right directions of Fig. 3) is of a size of 10 ~ 30mm (such as 20mm), be of a size of 2 ~ 6mm (such as 4mm) up and down, border between 1st recess 27 and the 2nd recess 28 be of a size of 1 ~ 5mm (such as 2.5mm) up and down, the side-to-side dimensions on border is 3 ~ 10 (such as 7mm).
"○" represents the situation obtaining straight current 32a, and "×" represents unavailable situation.
[table 1]
Result as shown in table 1, when the internal diameter r of part 1 16a is such as 8mm, as long as be more than 10mm from the distance L of introducing port 37 to nozzle 18, that is, as long as internal diameter r is 1: 1.25 with the ratio of distance L, just obtains straight current 32a.When distance L is less than 10mm, due to effectively rectification can not be performed, so current spread immediately after nozzle 18 spues, fail to obtain the current 32a of straight shape.
In addition, when the internal diameter r of part 1 16a is 15mm, as long as be more than 19mm from the distance L of introducing port 37 to nozzle 18, that is, as long as described ratio is 1: 1.27, just obtain straight current 32a.When distance L is below 18mm, current spread immediately after nozzle 18 spues, and fail to obtain the current 32a of straight shape.
In addition, when the internal diameter r of part 1 16a is 19mm, as long as be more than 23mm from the distance L of introducing port 37 to nozzle 18, that is, as long as ratio is 1: 1.21, straight current 32a is just obtained.When distance L is below 22mm, current spread immediately after nozzle 18 spues, and fail to obtain the current 32a of straight shape.
Result shown in table 1 represents, as long as described distance L is more than 1.21: 1 with the ratio of internal diameter r, can obtain the current 32a of straight shape.But if the ratio of distance L and internal diameter is more than 3: 1, then described distance L is elongated, and shower nozzle 10 maximizes, and not easily uses.
In addition, when nozzle 18 be of a size of described numerical value (direction of growing crosswise of the 2nd recess 28 is of a size of 20mm, be of a size of up and down the border of 4mm, the 1st recess 27 and the 2nd recess 28 be of a size of 2.5mm up and down, the side-to-side dimensions on border is 7mm), when the hydraulic pressure in discharge opening 14 is lower than 0.03MPa, although straight current 32a can be obtained, but, the flow of water of straight current 32a is weak, does not also become disperse state and just falls.Therefore, the hydraulic pressure in discharge opening 14 needs at more than 0.03MPa, preferably at more than 0.05MPa.At this, when described size increases, the hydraulic pressure in discharge opening 14 declines, so in this case, in order to obtain straight current 32a, what need increase running water supplies hydraulic pressure.In addition, increase with the hydraulic pressure in discharge opening 14, the length alpha of straight current extends.
In addition, each embodiment above-mentioned can be carried out following change to implement.
