Description
The invention technical field
The present invention relates to a kind ofly will be contained in the two-layered, formed toilet seat and the manufacture method thereof of toilet seat inside in the electric parts such as heater by embedding moulding.
Background technology
Shown in the profile-Figure 56 that is done as the vertical view among Figure 55 and along the cutting line A-A among Figure 55, heating toilet seat 600 comprises horseshoe-shaped heating toilet seat main body 602, by means of adhesive sheet 609 bondingly attached to the heater on the lower surface of above-mentioned toilet seat main body 602 606, and the base plate 608 of the bottom opening of the main body 602 of sealed toilet seat.When to heater 606 power supplies, this toilet seat main body 602 is heated.By heater 606 being bonded on the lower surface 604 of toilet seat main body 602, make the bottom opening of base plate 608 and toilet seat main body 602 couple together the manufacturing of finishing above-mentioned heating toilet seat 600 by ultrasonic wave coating coating method or the deposited coating method of hot plate then with adhesive sheet 609 or similar material.
On the heating toilet of making like this 600, because therefore resin shrinkage and produce narrow slit S inevitably for cause easy for installation makes between the bottom opening of toilet seat main body 602 and base plate 608 can be stained with dirt on the surface in narrow slit.This being bonded at around the lip-deep dirt of narrow slit can not be wiped with wet cloth easily.Another problem is its shape.Should make ultrasonic horn and base plate 608 be planar shaped, so that transmit energy equably.But from the design angle, this flat shape is unfavorable, and in addition, this influencing profiles, is difficult to so that the people is comfortably seated in top suitable curve form manufacturing consequently from ergonomic angle to the shape of toilet seat body 602.
For addressing these problems, known real the opening of Japan to make heater embed the method for toilet seat internal shaping shown in the clear 61-13685 communique (1985).Shown in Figure 57, this heating toilet seat has groove 624 on the upper surface 622 of supporting base material 620, each groove 624 has a manual heater 626 that embeds, should support then that base material 620 was placed in the injection forming mold 630, so that fill chamber 632 with resin, thereby supporting stacked formation one deck toilet seat main body (not shown) on the base material 620, heater 620 then is embedded in to be supported between base material 620 and the toilet seat main body.But, will be the operation of taking a lot of work very much in heater 626 embedded grooves 624.Another problem is, because the cause of injection pressure can make heater 626 deviate from groove, goes on the upper surface 622, thereby makes some part attenuation of toilet seat main body, therefore its intensity weakened.
Another kind of heating toilet seat in the past is published in Japanese patent publication communique spy and opens on the clear 61-247426 (1986).The manufacture method of this heating toilet seat is that the porous flake heater is placed in the injection forming mold, be injection molded into the precast body that flake heater and substrate are made of one, and then this precast body put into another injection forming mold, with stacked formation toilet seat main body on flake heater.But, this laminar heater is being placed under the situation of this large-area toilet seat, being difficult to produce can be with the whole evenly toilet seat of heating of toilet seat.Therefore, using under the situation of flake heater, can produce the problem that the surface of heating toilet seat can not evenly be heated.
In the time will imbedding toilet seat such as electric parts such as thermistor and fuse and heaters, the injection pressure of molten resin can make the placement location displacement of electric parts from them, thereby produces the problem that is difficult to various electric parts are embedded toilet seat.
Summary of the invention
The objective of the invention is to solve above-mentioned the problems of the prior art, provide a kind of its electric parts non-displacement ground simple two-layered, formed toilet seat and the manufacture method thereof that is molded on the assigned position that embed.
According to two-layered, formed toilet seat of the present invention, electric parts is housed in wherein, it is characterized in that described toilet seat comprises: by the ground floor of resin forming; Be contained in the lip-deep described electric parts of described ground floor; When described electric parts being embedded, be layered on the ground floor and the second layer that forms by injection mo(u)lding; And be located at the position of the described electric parts of vicinity on the described ground floor and be positioned at masking device for the upstream side that forms the molten resin flow that the described second layer injects at least, act on the injection pressure of the molten resin on the described electric parts in order to reduction.
Two-layered, formed toilet seat of the present invention, on the surface of electric parts attached to ground floor, and the described second layer of stacked formation on the ground floor, so that electric parts is embedded.In addition, masking device is located at the upstream side into the molten resin flow that forms the second layer, and is positioned at the position of contiguous electric parts.Described this masking device can reduce molten resin when forming the second layer and acts on pressure on the electric parts injecting molten resin, thereby can prevent that electric parts from floating and displacement.
Can adopt the slope that on the upper surface of ground floor, forms best way as above-mentioned masking device.Because described slope makes described molten resin flow to the top of described electric parts on its level and smooth surface, the injection pressure that acts directly on the side of electric parts will reduce.Structure and the preparation method of making the described slope of one with described ground floor are very simple.
The another kind of mode of above-mentioned masking device is to form a depression, makes the upper surface of the electric parts that is mounted in it almost concordant with the upper surface of ground floor; By electric parts being contained in this depression, molten resin flows to the top of electric parts smoothly from the upper surface of ground floor, can not apply very high injection pressure on the side of electric parts.
The another kind of mode of described masking device is to use flexible sheet.Can reduce to act on injection pressure on the electric parts with this sheet material coating electrical part.Because sheet material can deflection, no matter so it can cover the electric parts of any profile.
So long as can bring electric function to toilet seat, various electric parts can adopt.For example, as the element of the situation of sitting down that detects toilet seat, can comprise the electrode and the piezoelectric transducer of limit switch, capacitance type sensor.Under situation, except that heater, also comprise the temperature sensor of detection toilet seat surface temperature and thermal cut-off etc. with the heating toilet seat on heater heating toilet seat surface.
If a toilet seat has the ground floor and the second layer, and embeds electric parts between two-layer, Here it is a complete two-layered, formed toilet seat.But, best mode is to adopt such structure, be the horseshoe-shaped support base material that is that ground floor adopts a top that is bearing in water closet, and the second layer adopt its part and the toilet seat main body top thermal welding, that have the toilet seat surface of supporting base material.
After electric parts being embedded between the ground floor and the second layer, because the thermal welding area of the caused ground floor of part of electric parts and the second layer reduces and bonding strength is reduced; But, will prevent the reduction of the bonding strength between the ground floor and the second layer on the ground floor and the second layer by depressed part and the jut make the chimeric mutually and hot melt adhesion of the ground floor and the second layer is set.
Electric parts need be from the binding post of external power source, and this binding post is suitably installed with following structure.That is, binding post is enclosed in the installing hole that forms on the ground floor, and by its supporting.At this moment, the top of binding post is stretched out in installing hole.Owing to the second layer of injection mo(u)lding on ground floor makes the top of binding post fix with the embedding state, therefore can when the second layer is shaped, binding post be installed, thereby make its mounting structure and fitting operation obtain simplifying.
In addition, with binding post is chimeric when being bearing in the installing hole, if do the internal diameter of installing hole more much bigger than the external diameter of binding post, so that carry out chimeric simply and supporting, the molten resin of the second layer just is easy to flow into installing hole.But, by top, be applied to the injection pressure of the gap location between binding post and the installing hole with reduction with sheet material sealed wiring terminal, just can avoid making the space between molten resin inflow installing hole and the binding post.
According to the manufacture method of two-layered, formed toilet seat of the present invention, wherein, go out the ground floor and the second layer with laminated resin, between the ground floor and the second layer, set electric parts simultaneously, it is characterized in that, comprise following operation: the operation that forms ground floor; Go out the second layer by injection moulding is stacked, make described electric parts be embedded in operation on the described ground floor; Before the operation of the stacked formation second layer, also comprise electric parts is installed on the ground floor, the position of the vicinity described electronic component of while on described ground floor, and be positioned at least for forming the upstream side of the molten resin flow that the described second layer injects, the operation of masking device that acts on the injection pressure of the molten resin on the described electric parts in order to reduction is set.
In the manufacture method of two-layered, formed toilet seat, with after the ester moulding ground floor, on ground floor, be laminated into the type second layer by injection mo(u)lding, carry out before this electric parts and masking device are contained in operation on the ground floor.Owing to the upstream side at the molten resin flow that injects in order to the formation second layer is provided with in order to reduce the masking device of molten resin injection pressure, can avoid the electric parts change in location that causes by this injection pressure, and avoid because the skew of electric parts or like parts and on the second layer, produce thin especially part.
In this case, because injection pressure is the highest injecting near the cast gate of molten resin, therefore preferably masking device is located on the position near the upstream side of this cast gate.
The order that electric parts and masking device are installed on the ground floor is not done special provision; Except taking to make electric parts and the integrated operation of masking device, also can after being installed in electric parts on the ground floor, masking device be installed again with the formation assembly.

The best mode that carries out an invention
Fig. 1 is the perspective diagram that the Western water closet 20 that the heating toilet seat that relates to one embodiment of the present of invention is housed is shown.As shown in Figure 1, Western water closet 20 be equipped with toilet bowl body 22, pivotally be bearing in an end of toilet bowl body 22 heating toilet seat 40 and toilet seat cover 26, the sanitary flush device 30 of cleaning (operating) water nozzle is housed, and waste preventer 28.
Above-mentioned heating toilet seat 40 is equipped with shape of a hoof toilet seat main body 50 shown in Figure 2, and support base material 60 shown in Figure 3, and described support base material forms toilet seat main body 50 inner embeddings.Fig. 2 is the vertical view of toilet seat main body 50, and Fig. 3 is a vertical view of supporting base material 60; Fig. 4 is the profile of being done along the cutting line B-B shown in Fig. 2.As shown in Figure 3, on the upper surface 62 of supporting base material 60, form the heater mounting groove 64 that is by profile shown in the dotted line.On the upper surface between the heater mounting groove 64 62 and peripheral part, form bonding plane 66.
Above-mentioned toilet seat main body 50 is that PP (polypropylene) resin that 200 ℃ ABS resin or fusing point are 180 ℃ is made by fusing point, and supports base material 60 also to be made by the same resin material.Therefore, when the molten resin in order to shape toilet seat main body 50 contacts with support base material 60, support the surface of base material 60 to melt together, and stick together with main body fully with the resin that injects.Though when molten resin contacts with support base material 60, make the surface melting of supporting base material 60, contact that the temperature of molten resin is reduced, thereby the inside of support base material 60 will can not melted.Use ABS resin or PP resin can obtain good surface appearance and reduce manufacturing cost.
As shown in Figure 5, heater 70 is arranged between the upper surface 62 and toilet seat main body 50 of supporting base material 60.The conducting strip 74 that heater 70 comprises the heater 72 that embeds in the heater mounting groove 64, made by aluminium foil, and be bonded at the adhesive sheet of making by two-sided tape 76 on the conducting strip 74; Conducting strip 74 and adhesive sheet 76 almost cover the entire area of upper surface 62, thereby make heater 72 remain on the inside of heater mounting groove 64.
The manufacture method of heating toilet seat 40 will be described below.
At first, support base material shown in Figure 3 60 is made by injection mo(u)lding.As shown in Figure 6, will be as first bonding plane 77 of the one side of adhesive sheet 76 attached on the conducting strip 74, then, with heater 72 attached on second bonding plane 78 as another side.Operate with supporting station 100.A plurality of shop bolts 102 that move up and down by the spring spring are housed on supporting station 100, arrange these shop bolts 102 consistent with the shape of heater mounting groove 64 on supporting base material 60.Then, heater 72 is placed between the shop bolt 102, will be pressed on the one side of heater 72 attached to the adhesive sheet on the conducting strip 74 76 with the preforming device (not shown) again.This operation with shop bolt 102 to pressing down, so just make heater 72 attached on the adhesive sheet 76.When conducting strip 74 and adhesive sheet 76 were mentioned, heater 72 and conducting strip 74 were sticked together by adhesive sheet 76, form an integral body.The upper surface of each shop bolt 102 scribbles and makes it be easy to the Teflon coating such as (polytetrafluoroethylene (PTFE)) that breaks away from from second bonding plane 78 of adhesive sheet 76.
In following step shown in Figure 7, in the heater mounting groove 64 on the heater 72 embedding support base materials 60 of heater 70, second bonding plane 78 with adhesive sheet 76 is attached on the bonding plane 66 of supporting base material then.Then, as shown in Figure 8, the support base material 60 that heater 70 or similar device are housed is placed between the patrix 112 and counterdie 114 of the metal pattern 110 of forming injection moulding machine.At this moment, between the wall of conducting strip 74 and patrix 112, form cavity 115.Then, as shown in Figure 9, molten resin R is injected in the cavity 115 by cast gate 116.Then, after cooling and solidifying, the resin molded body of the demoulding is taken out from mould, so just finished the manufacturing of heating toilet seat 40.
In the above-described embodiments, heater 72 is embedded in the heater mounting groove of supporting on the base material 60 64, cover then with conducting strip 74.Like this, conducting strip 74 makes smooth surface towards heater 72, it is bonded on the upper surface 62 of supporting base material 60 tightly, and adhesive sheet 76 is bonded between them.Therefore, heater 72 just can not pushed on one side at the injection pressure bottom offset of molten resin R or by this pressure when injection mo(u)lding.Therefore, just do not have the local attenuation on toilet seat main body 50 that skew caused, thereby just do not have the intensity reduction that causes owing to attenuation yet owing to heater 72.
Owing to keep the conducting strip 74 of heater 72 to be made by aluminium foil, so the heat on the heater 72 is delivered to toilet seat surface 52 effectively, has only very little thermal losses.
In addition, in the process that conducting strip 74 is engaged with heater 72, if conducting strip 74 and adhesive sheet 76 are pressed on the heater 72, and heater 72 is placed between the shop bolt 102 of supporting station 100, heater 72 just in the mode of arranging along heater mounting groove 64 bondingly attached to the surface of conducting strip 74.Therefore, if do the size of heater mounting groove 64 more greatly, heater 72 is embedded the operation that bothers the narrow groove 72 with regard to not needing to resemble; Like this, the operation of installation heater will be very simple.Otherwise, if heater mounting groove 64 is done very narrowly, then can use the lower adhesives of adhesive strength, so still can make the operation that heater 70 is installed become very simple.
Toilet seat main body 50 and support base material 60 are made one by embedding to be shaped.Like this, owing to do not have the space, therefore be easy to clean at joint.Heating toilet seat 40 can not rely on the profile of supporting base material 60 and takes various profiles; Therefore, toilet seat can take best design to make, and makes it have extremely comfortable profile.
Below explanation is related to other embodiments of the invention.Figure 10 relates to the profile of amplification of the heating toilet seat 40A major part of another embodiment.As shown in figure 10, heater mounting groove 64A forms on the support base material 60A of heating toilet seat 40A.Two heaters 72 of heater 70 are embedded heater mounting groove 64A, and the space between two heaters 72 forms heater side dimple 70a.The projection 50a of toilet seat main body 50A and this heater side dimple tabling.
For making above-mentioned heating toilet seat 40A, at first to make heater 70A.As shown in figure 11, on supporting station 100A, shop bolt 102 is lined up two row.Distance between the two row shop bolts 102 almost with the heater mounting groove 64A that will pack in two heaters 72 between distance equate.Then conducting strip 74 is placed on the shop bolt 102 of heater 72, with preforming device 104 this conducting strip 74 is pressed on the heater 72 again.A grooving 104a is arranged on preforming device 104.Like this, as shown in figure 12, heater 72 links to each other, has simultaneously the heater side dimple 70a of the shape that is grooving 104a with conducting strip 74 heater 70A has just been made by adhesive sheet 76.
In next step, the heater 72 of heater 70A is embedded in the heater mounting groove 64A that supports on the base material 60A, and make on the wall of base attached to heater mounting groove 64A by adhesive sheet 76.On the bottom surface of bottom of heater side dimple 70a attached to heater mounting groove 64A.At this moment, because the area of section of heater mounting groove is more a lot of greatly than the sectional area of two heaters 72, so the operation of heater 72 embeddings is very simple.
Next step shown in Figure 13 is injection mo(u)lding, and the support base material 60A that will be equipped with heater 70A this moment is placed in the metal pattern 110.At this moment,, at first flow through the plane cavity part 115a of conducting strip 74, be full of the dimple 115b that forms by heater side dimple 70a then gradually molten resin R filling cavity 115A.Therefore, after molten resin R was full of dimple 115b, injection pressure was very low, thereby heater 72 will be removed from heater mounting groove 64A, had also avoided occurring on toilet seat main body 50A thin part.
In the embodiment shown in Fig. 1 to Figure 13, heater 70 or 70A have a kind of structure, and in this structure, adhesive sheet 76 is attached to the one side of conducting strip 74, and heater 72 is attached on the adhesive sheet 76, but this is not unique possible structure.As shown in figure 14, heater 72 can be placed between conducting strip 74B and the adhesive sheet 76B.In this case, as shown in figure 15, also make the inboard of the second bonding plane 78B of adhesive sheet 76B, thereby adhesive strength is increased, because heater 72 directly contacts with conducting strip 74B, heat transfer efficiency is also increased simultaneously attached to heater mounting groove 64.As shown in figure 16, if will make at the bonding plane 66B between the heater mounting groove 64B, the embedding operation that heater 72 is located in heater mounting groove 64B be more prone to a little less than upper surface 62.
Shown in Figure 17 and 18, between conducting strip 74C and adhesive sheet 76C, can place the heat shield of making by polyester or similar material 79.This will be avoided making heat to the 60 1 side transmission of support base material, and heat is increased greatly from the transmission efficiency of heater 72 to the toilet seat surface.In this case, in order to reinforce three-decker, a part of heat shield 79 can be cut, so that adhesive sheet 76C directly links to each other with conducting strip 74.
In Figure 19, embed the structure that the interior support base material 60E of toilet seat main body 50E has hollow.In this embodiment, because heating toilet seat 40E itself is thereby that to obtain lighter weight by per unit volume also be to make by the mode that the material that uses as much obtains bigger volume, thereby make people that a kind of high-quality impression be arranged by sensation to its volume.If buffer part 150 is placed under the bottom 69 of supporting base material 60E, the height that makes the toilet seat main body is lower than when making the directly height during formation under the 62E of top of buffer part 150, and can simplifies the cleaning of the seam peripheral region of buffer part 150.
As shown in figure 20, toilet seat main body 50 can form around the whole profile that comprises the bottom 69 of supporting base material 60F.This will improve the appearance design of product biglyyer.
Figure 21 illustrates the end profile of another kind of heating toilet seat 40G.If conducting strip 74G is placed between support base material 60G and the toilet seat main body 50G, bonding strength will reduce; For avoiding this situation, can adopt being removed to various structures:
1) cuts by some part and form window 75, and make toilet seat main body 50G and support base material 60G by these window 75 deposited being integral with conducting strip 74G.
2) on conducting strip 74G, form in the window 75, on the upper surface 62 of supporting base material 60G, form a position corresponding grooves 63 with this window 75.When injection mo(u)lding toilet seat main body 50G, molten resin flows into groove 63 by window 75, forms projection 53.Make toilet seat 50G thus and support the bonding area of base material 60G to increase.
3) form groove 67 in the end of supporting base material 60G.When injection mo(u)lding toilet seat main body 50G, molten resin flows into groove 67, forms the maintaining part 58 as the part of toilet seat main body 50G, to keep supporting the end of base material 60G.The bonding area that this will increase toilet seat 50G and support base material 60G.
4) sheet material a kind of aluminum and scribble resin on its two sides is used as conducting strip 74,, thereby engages forcefully with adhesive sheet 76 so that toilet seat main body 50G improves the deposited effect of resin by the resin coating.
Figure 22 and 23 is illustrated in the manufacture method that the seam crossing of supporting base material and toilet seat main body does not produce the heating toilet seat of overlap.Metal pattern 110H on the injection moulding machine comprises patrix 112H, counterdie 114H and sliding die 118; Sliding die 118 is positioned at the seam 60h place that supports base material 60H and toilet seat main body, and constructs to such an extent that slide up and down along the direction shown in the arrow among the figure.When injection mo(u)lding, the molten resin R of filling chamber 115H arrives sliding die 118, and the resin pressure in the starting stage is born by sliding die 118.Thereafter with sliding die to lower slider.After sliding die 118 was removed, molten resin R was full of chamber 115H gradually.That is to say, when molten resin R arrived the seam 60h place that supports base material 60H, the high resin pressure at its injection moulding initial stage was at first born by sliding die 118, after resin pressure reduces, when removing sliding die 118 and being full of chamber 115H, moltenly touch resin R and directly contact with seam 60h.Therefore, molten resin R does not have very high injection pressure at the seam 60h place that supports base material 60 and toilet seat main body, thereby does not produce overlap at the seam 60h place that supports base material 60H and toilet seat main body.
Figure 24 to Figure 35 illustrates another kind of embodiment.
The heating toilet produces 40L and comprises horse tellurium shape toilet seat main body 50L shown in Figure 24, and embedding shown in Figure 25 is formed in the support base material 60L in the toilet seat main body 50L; Figure 24 is the vertical view of toilet seat main body 50L, and Figure 25 is a vertical view of supporting base material 60L; Figure 26 is the profile of being done along the cutting line C-C among Figure 24; Figure 29 is the profile of being done along the cutting line D-D among Figure 24; As shown in figure 25, being used for the plane 62La that heater installs forms on the end face 62L that supports base material 60L.As shown in figure 29, covering projection 62Lb forms at an end of supporting base material 60L.
As Figure 26 and amplify shown in Figure 27ly, heater 70L is contained between the upper surface 62L and toilet seat main body 50L that supports base material 60L.Heater 70L comprises the heater that places on the heater mounting plane 62La that supports base material 60L, the conducting strip 74L with aluminium foil system of big rigidity, and bonding attached to the double-sided adhesive sheet 76L on this conducting strip 74L; Conducting strip 74L and adhesive sheet 76L cover the upper surface of heater 72L and the almost all surfaces of supporting the upper surface 62L of base material 60L.As shown in figure 27, when conducting strip 74L covered heater 72L, its shape resembled a hill with inclined-plane 74La of mild transition.As shown in figure 28, the vertex angle theta of inclined-plane 74La is in 90 ° to 130 ° scopes.As the enlarged drawing of the major part of Figure 29-shown in Figure 30, except with covering the heater lead 72La that projection 62Lb is capped, conducting strip 74 almost covers heater 72L fully with the hill shape with mild transition.In order to strengthen supporting the joint between base material 60L and the toilet seat main body 50L, the part of conducting strip 74 and adhesive sheet 76L is cut, form the window (not shown).
The manufacture method of heating toilet seat 40L will be described below.
At first, support base material 60L shown in Figure 25 is made by injection mo(u)lding.At one independently in the manufacturing process shown in Figure 31, the first bonding plane 76L of the one side of adhesive sheet is attached on the conducting strip 74L, and the second bonding plane 78L is attached on the heater 72L.Supporting station 100L is used for this operation.A plurality of shop bolts 102 are housed on supporting station 100L, and these pins move up and down by spring.These shop bolts 102L copies to be placed on and supports the arrangement position of the heater 72L on the base material 60L to arrange.Then, heater 72L is placed between the shop bolt 102L, will be pressed on the one side of heater 72L attached to the adhesive sheet 76L on the conducting strip 74L with the preforming device (not shown) again.This operation with shop bolt 102L to pressing down, so just make heater 72L attached on the adhesive sheet 76L.In next stage,, made the heater 70L that heater 72L and conducting strip 74L is bonded into an integral body by adhesive sheet 76L by conducting strip 74L and adhesive sheet 76L are mentioned.The upper surface of each shop bolt 102L scribbles and makes it be easy to polytetrafluoroethylene (PTFE) or the similar coating of peeling off from the second bonding plane 78L of adhesive sheet 76L.
In following step shown in Figure 32, the heater 72L of heater 70L is placed on supports on the base material 60L that the second bonding plane 78L with adhesive sheet 76L is attached on the heater mounting plane 62La that supports base material 60L then.At this moment, as shown in figure 28, conducting strip 74L is at the part protuberance of heater 72L.But,, therefore form and relax slope 74La and bondingly attached on the heater mounting plane 62La because conducting strip 74L is to use the bigger sheet material of rigidity.As shown in figure 30, the conducting strip 74L of the heater lead 72La of covering heater 72L also covers and supports the outstanding 62Lb of covering of base material 60L.
Then, as shown in figure 33, the support base material 60L that heater 70L or similar device are housed is placed between the patrix 112L and counterdie 114L of the metal pattern 110L that forms injection moulding machine.In this state, the position of the cast gate 116L of metal pattern 110L is located at and supports the covering on the relative position of projection 62Lb of base material 60L.After placing support base material 60L, between the wall of conducting strip 74L and patrix 112L, form chamber 115L.Then, as shown in figure 34, molten resin R is injected in the 115L of chamber by cast gate 116L.Molten resin R flows into along direction shown in the arrow among Figure 35 from cast gate 116L, and is full of chamber 115L.Then, after cooling and solidifying, release resin molded body is taken out from mould.Then, the manufacturing of heating toilet seat 40L has been finished in the operation of the connection by carrying out fuse not shown in the figures etc.
In the above-described embodiments, because above-mentioned conducting strip 74L covers the heater 72L that supports on the base material 60L with the little chevron of band flat grade, therefore, the molten resin R that is injected by cast gate 116L flows through conducting strip 74L as shown in figure 34 smoothly.Because the molten resin R of high injection pressure does not act directly on the heater 72L, therefore, heater 72L can not be offset or be pushed on one side, and its result can not have local attenuation owing to the skew of heater 72L on toilet seat main body 50L, thereby just can not reduce owing to attenuation causes intensity.In addition, because above-mentioned operation covers heater 72L with conducting strip 74L with wide, gentle incline, and the high sheet material of the available rigidity of conducting strip 74L itself forms, so simplifies the structure and manufacturing operation.
Owing to keep the conducting strip 74L of heater 72L to make by aluminium foil, the heat from heater 72L is delivered on the 52L of toilet seat surface effectively, have only very little thermal loss.
In addition, in the above-described embodiments, though the injection pressure that acts near the support base material 60L the cast gate 116L is very high, but because the locational projection 62Lb that covers that is located near cast gate 116L prevents to make the very high injection pressure of molten resin to act on the heater lead 72La of heater 72L, thereby can prevent the displacement of heater lead 72La.
In the above-described embodiments, the cast gate 116L of metal pattern 110L is located at the outer rim of supporting base material 60L, is located on the position of the support base material 60L that this cast gate 116L faces toward and cover projection 62Lb.But as shown in figure 36, if cast gate 116M is placed on the inwall, molten resin R flows the direction of following the arrow; Therefore, as shown in figure 37, should place on the inwall relative covering projection 62Mb with cast gate 116M.
Figure 38 illustrates the injection mo(u)lding operation of the manufacturing heating toilet seat among another embodiment.On the surface of the support base material 60N the cast gate 116N near, form heater mounting groove 63Nb, the heater lead 72La of heater 72L is remained in this heater mounting groove 63Nb.Because heater lead 72La keeps securely by heater mounting groove 63Nb, thereby this lead-in wire will be shifted from the higher injection pressure of the molten resin R of cast gate 116N.The operation of heater lead 72La being inserted heater mounting groove 63Nb just just needs near cast gate 116N, rather than needs on all surfaces of supporting base material 60N, thereby does not need a lot of artificial.Except near a heater mounting groove of the formation 63Nb cast gate 116N, can also form a plurality of heater mounting groove 63Pb as shown in figure 39, thereby the injection pressure of making and resin flow are complementary, so that this heater mounting groove 63Pb keeps heater lead 72La.
Except making the conducting strip, can adopt the multiple mode that covers heater with conducting strip with the aluminium foil of high rigidity.Can use the adhesive sheet of rigidity or fill heater and the seam of supporting base material, with conducting strip they be covered then with resin plaster or materials similar.
In the paragraph below explanation is installed in the fuse syndeton of the heater 70 of heating toilet seat 40.As shown in figure 40, four buffer part 150 that contact with toilet bowl body 22 form at the back side of heating toilet seat 40.In these buffer part, shown in the profile in Figure 41 and 42, buffer part 150A holds fuse 180.That is to say that buffer part 150A comprises jut 152 and bolster 190, this jut 152 is dashed forward with elliptical cross-sectional shape from the bottom of supporting base material 60 with being integral and is set out, and it has accommodating chamber 154; This bolster 190 is packed into by forced stop plug 192 in the opening of accommodating chamber 154.
Through hole 156a and 156b are installed form on the top of buffer part 150A, and lead to the upper surface 62 of supporting base material 160 from accommodating chamber 154, as shown in figure 43, the bottom that through hole 156a and 156b are installed is a section contraction flow region 162. Terminal 170a and 170b are inserted by installing hole 156a and 156b.As shown in figure 44, terminal 170a comprises a upper terminal portion 171 that links to each other with the lead-in wire 72a (72b) of heater 72, heaves portion 172 and lower terminal portion 173 with 170b.Heave portion 172 and contact, so that the lower seal of through hole 156a and 156b will be installed with above-mentioned section contraction flow region 162 pressure.Insulating tape 188 is bondingly on the assigned position attached to the upper surface 62 that is placed with guidance part 72a and 72b and terminal 170a and 170b.This insulating tape 188 is bondingly attached to cutting on the part on the thermal conductive belt 74, to prevent that molten resin from entering installing hole 156a and 156b when the injection mo(u)lding.
The fuse 180 that is used to prevent the overcurrent of heater 72 links to each other with the lower terminal portion 173 of above-mentioned terminal 170a and 170b by portion of terminal 182.This fuse 180 is cast in the resin filling materials of being made by silicon rubber or similar material 184, and insulate with moisture or other foreign medium.
According to the structure of buffer part 150A, allow to use the accommodating chamber 154 among the buffer part 150A to hold fuse 180, so just make mounting structure than the simple in structure of fuse 180 externally is installed.
As shown in figure 44, the end of terminal 170a and 170b forms the portion of heaving 172 respectively, and by closely contacting with section contraction flow region 162 through hole 156a will be installed and 156b fully seals, thereby makes molten resin can not enter accommodating chamber 154 when injection mo(u)lding.
The termination that can freely install and remove on the heater 72 of heating toilet seat 40 will obtain explanation below, and shown in Figure 45 and 46.
An end 40a who packs termination into heating toilet seat 40 shown in Figure 2 is in order to couple together heater and external power source by electric wire 220.Figure 45 illustrates the off-state of termination 200, and Figure 46 illustrates its connection status.As shown in figure 45, termination 200 comprises a positive socket 210 and the cloudy plug 230 that can freely install and remove that is contained in the lower end of supporting base material 60 on this sun socket 210.Sun socket 210 comprises the sleeve 212 that inserts the support 61 that is positioned at an end of supporting base material 60.Step projection 215 and four connecting through hole 214a, 214b, 215a and 215b (seeing Figure 47) form on sleeve 212; Male 216a and 216b are pressed into connecting through hole 214a and 214b, and will fall 217b with the male 217a that thermistor 310 is connected and be pressed into connecting through hole 215a, 215b.The copulational protuberance 218 that two its ends have junction surface 218a stretches out at the outer circumference end place of sleeve 212.
Cloudy plug 230 comprises a shell 240 and a connector 250 that is housed in the shell 240.Connector 250 comprises a fixed component 260, a movable member 270 and a stop dog component 280.At the front end of above-mentioned shell 240, form an engaging claw 244 that will engage with joint dimple 219 in convex plug 210 1 sides.Rear end at shell 240 forms the through hole 242 that electric wire 220 is free to slide therein.Electric wire 220 can slide with connector 250 in through hole 242, but this motion is subjected to the limitation of shoulder 222.
Bottom at the sliding cavity 262 of said fixing member 260 is formed with gathering sill 264 and directed cavity 266, and the direction protrusion 272 and 274 that forms on movable member 270 can be entrenched in gathering sill 264 and the directed cavity 266 with being free to slide.Spring 292 and 294 is housed in gathering sill 264 and the directed cavity 266, and applies elastic force, uses so that movable member 270 slides with respect to fixed component 260.The slippage of movable member 270 is subjected to the restriction of the projection 282 on the stop dog component 280.Movable member 270 is each relaying terminal 300 molded forming that will have male 302 and cloudy terminal 304 with resin.Do above-mentioned male 302 to such an extent that can be connected with cloudy terminal 226 or separate, do anion 304 to such an extent that can be connected with male 216a, 216b etc. or separate.
Following paragraph illustrates the attended operation of above-mentioned termination 200.
Under disengaged condition shown in Figure 45, connector 250 moves to the left side of figure with electric wire 200, and with till shoulder 222 contacts, connector 250 is in free state in shell 240 until it.With 294 elastic force movable member 270 is separated by spring 292 with fixed component 260, make male 302 and cloudy terminal 226 be in released state.
For termination 200 is become connection status shown in Figure 46 from off-state, hand-held connector 250 pushes male 216a and 216b with the cloudy terminal 304 of relaying terminal 300, whereby, movable member 270 antagonistic springs 292 that pushing by outstanding stage portion 215 and 294 elastic force and be pressed into, thus male 302 is linked to each other with cloudy terminal 226.At this moment, the junction surface 218a on convex plug 210 sides is chimeric with the copulational protuberance 268 on fixed component 260, thereby connector 250 is fixed on the positive socket 210.Like this, 216a and male such as 216b just relaying terminal 300, the cloudy terminal 226 by being sealed by connector 250, be connected electric wire 224 and be connected with external power source with electric wire 220.Thereafter, hand-held housing 240 is advanced towards positive socket 210 1 side pressures, and shell 240 and positive socket 210 are assembled together.
Because male, relaying terminal 300 and cloudy terminals 226 such as 216a and 216b are by connector 250 sealings, therefore above-mentioned termination 200 has fabulous water resistance.
When with cloudy plug 230 when positive socket 210 is pulled up, spring 292 makes the movable members 270 in the cloudy plug 230 separate with cloudy terminal 226 with relaying terminal 300 with 294 elastic force.Because relaying terminal 300 is so to cut off with external power source, so these relaying terminals can prevent fully that any electricity from leaking.
In addition, when with cloudy plug 230 when positive socket 210 is pulled up because external cable do not link to each other with heating toilet seat 40, thereby do not have obstacle when carrying out such as attended operations such as cleanings, make this generic operation be easy to carry out.
Except these advantages,,, so be difficult to make connector 250 from positive socket 210, to throw off with external force again because the outside strain of shell 240 restriction copulational protuberances 218 because junction surface 218a and copulational protuberance 268 are chimeric.
The following describes is shaped in the embedding by heater 70 makes in the operation of heating toilet seat 40, the manufacturing process the when fuse 180 of buffer part 150A and termination 200 are assembled simultaneously.
In the phase I, as shown in figure 47, sleeve 212 is pressed in the support that is fixed on support base material 60.Before this, male 216a, 216b and 217a and 217b are pressed into are fixed in the sleeve 212 earlier.Then, the lead-in wire 312 of thermistor 310 is linked to each other with male 217a with 217b, thermistor 310 temporarily is fixed on the upper surface of supporting base material 60.
In next stage, heater 70 is contained on the support base material 60.To shown in Figure 9, this operation realizes above the basal plane 60 attached to supporting by making conducting strip 74 or like parts bondingly as Fig. 6.Thermistor 310 also is fixed on by conducting strip 74 and supports on the base material 60.
In next stage, the lead-in wire 72a of an end of heater 72 is linked to each other with male 216a in being fixed on sleeve 212.Terminal 170a is linked to each other with the lead-in wire 72b of the other end of heater 72, then this terminal 170a is pressed among the installation through hole 156a that embeds the top that is in buffer part 150A.Terminal 170b is linked to each other with the lead-in wire 320a of an end that interrupts electric wire 320, this terminal 170b is pressed to embed among the connecting through hole 156b then.The lead-in wire 320b of the other end of relaying electric wire 320 is engaged with other male 216b in being fixed on sleeve 212.
Wrap with insulating tape 360 some part in next stage, and each male 216a, 216b, 217a and the 217b that will be positioned at the upper surface of sleeve 212 with insulating tape 32 wrap respectively terminal 170a and 170b and relaying electric wire 320.Insulating tape 360 and 362 is made by the sheet material with insulating properties in the part that covers terminal and other part.Then, the support base material 60 that heater 70 and other part are housed is put into the metal pattern of injection moulding machine, to form toilet seat main body 50 by injection mo(u)lding.After the cooling, formed body is taken out.
In next stage, as shown in figure 41,, and the portion of terminal 182 of fuse 180 is linked to each other with 156b with installation through hole 156a with the accommodating chamber 154 in the fuse 180 insertion buffer part 150A.Then, resin fill material 184 is injected in the accommodating chamber 154,, then, be pressed into accommodating chamber 154 by stop plug 192 bolster 190 is installed bolster 190 with cast fuse 180 and other part.This has just finished the manufacturing of heating toilet seat 40.
Therefore, if heating toilet seat 40 is manufactured by said method, as long as carried out the simple assembly process of fuse 180 and other part before injection mo(u)lding, fuse 180 among the buffer part 150A and termination 200 do not need to carry out the complicated procedures of forming after the injection mo(u)lding of toilet seat main body 50.
Figure 48 is illustrated in other manufacture method that fuse 180 is loaded onto in injection mo(u)lding before.
In the phase I, terminal 170a and 170b are pressed among the installation through hole 156a and 156b that supports base material 60I, and heater 70 is contained on the support base material 60I.Then, fuse 180 is linked to each other with 170b with terminal 170a, make then to have to be contained in the lower surface of supporting base material 60I around the bolster 68 of the shape of fuse 180.Be formed with pore 68a and 68b in the bottom of bolster 68.
In next stage, will support base material 60I and other part to be placed among the metal pattern 110I on the injection moulding machine.In this state, the toilet seat main body forms by injection mo(u)lding, and fuse 180 is then by such as the cooling of cooling gas flows such as the nitrogen of the pore 68a that flows through, accommodating chamber 154I and another pore 68b and air.After injection mo(u)lding, load onto the bolster (not shown).In order to increase waterproof effect, can be by through pore 68a with 68b pours into silicon rubber or other material is poured into a mould fuse 180.Compare with embodiment shown in Figure 41 and since fuse 180 can be contained in not the support base material 60 that centered on by projection 152 or other part below, the installation effectiveness of this embodiment is improved.
Figure 49 to Figure 51 illustrates termination and the relevant portion thereof with another kind of structure.The termination of heater 72 is to form like this, is about to sleeve 212J pressure and inserts and be fixed in the support 61J, male 216 is pressed again and inserts and be fixed in the sleeve 212J, forms toilet seat main body 50J by injection mo(u)lding then.
Below each section the manufacture method of above-mentioned joint design will be described.In the phase I, under pressure, sleeve 212J is inserted and secured in the support 61J that supports base material 60J.Four male 216 have been pressed in the sleeve 212J.In four male 216 two link to each other with a thermistor (not shown) or other parts; Make heater 70 attached on the upper surface 62 of supporting base material 60J, male 216 is linked to each other with the lead-in wire of heater 72.Then, with male 216 insulating tape 362 on the top cover, will insert the lower ending opening portion that ring 380 is contained in support 61J again.To support base material 60J etc. to place in the metal pattern of injection moulding machine then, to form toilet seat main body 50 by injection mo(u)lding.
After injection mo(u)lding, will couple together with male 402 grades at the cloudy plug 400 that its front end has a cloudy terminal 402.At the front end of cloudy plug 400, " O " type circle of a sealing usefulness is housed between the conical surface of itself and support 61J.The hexagon resin nut 410 that inside is embedded with cloudy plug 400 is attached thereto by the screw thread that inserts ring 380.Cloudy terminal 402 is connected with male 216 securely with sealing state.
If on the screw thread inwall of hex nut 410, the projection (not shown) is set, this projection will increase the connection resistance of hex nut 410, can by send answer sound make it to have the sensation of loading and unloading, even and under the situation of not using erecting tools, also can avoid loosening.
Figure 52 to 54 illustrates the another kind of structure of termination 450; Figure 52 illustrates its disengaged condition, and Figure 53 illustrates its connection status; Figure 54 is the profile of being done along the cutting line G-G among Figure 53.
Above-mentioned sliding component 490 is with the end of electric wire 220, connects the resin molded and formation of electric wire 224 and terminal base portion 227 usefulness.Above-mentioned connecting elements 500 comprises the termination contact portion 504 that links to each other with above-mentioned terminal base portion 502, and with this termination contact portion 504 and with the copulational protuberance 506 of above-mentioned socket portion 462 tablings.On the outside portion of attaching parts 500, be formed with the chimeric embeded slot 508 of junction surface 464a with positive socket 460 sides.
Be formed with and the chimeric copulational protuberance 552c of junction surface 464c on the side of positive socket 460 at the front end of above-mentioned shell 550, be formed with the through hole 554 that electric wire 220 can be free to slide therein in the rear end of shell 550.Electric wire 220 and connector 480 constitute the one that can move in through hole 554.
