Technical field
The present invention relates to a kind of continuous heaters that is used to provide the electricity of hot water; Comprise: the main body of on length and width and high size, extending; This main body have main body front, the main body back side, main body positive with the main body back side between on height dimension the body rim face, the cavity of constructing at the partial interior of the integral body of main body of decision body height; Wherein, the main body back side forms rear wall, and the humidity district of reverse side is separated with positive dry place; Wherein the body rim mask has the edge of opening face, and cavity utilizes opening to open wide in this edge of opening face; Belong to the lid marginal portion with the lid outside edge of opening face, that cover this edge of opening face; Wherein, On the body rim face of imperforation edge surface, be configured with the body rim contact pin of outside projection, and on the lid outside, be configured with the lid edge contact pin of outside projection; Shell; Main body is in this shell; Wherein, Main body and lid marginal portion be through being adjacent to each other transverse to the boundary seam of body rim contact pin with lid edge contact pin, wherein body rim contact pin and lid edge contact pin form between the main body that is inserted in continuous heaters and the shell, to the sealing contact pin of the contact pin system of injection water sealing.
Background technology
The continuous heaters of the known electricity of said type is peculiar to be; Main body forms particularly whole fixing body; In the front of fixing body, promptly install or be provided with the element of electric heater unit in the dry place between front in it is in continuous heaters or inboard and the shell.What belong to this element for example has circuit board and accessory thereof, particularly electronic broken circuit element, for example triac, transformer, capacitor and a heating muff.The sealing contact pin of contact pin system accurately ordinatedly with the inner seal ground adjacency that be the shell of the positive hood-shaped formula of device cover mostly, make and drip water, splash water and/or injection water and can not enter in the dry place.Usually, the edge contact pin that the edge contact pin that covers is promptly covered on edge contact pin and the main body is body rim contact pin, is flat rib shape contact pin mostly on height dimension.They can have by determining deviation gap that stagger each other, gap-like.Therefore not only form the sealing system that prevents that external water from getting into, and formed the assurance condensed water enters moist space from dry place labyrinth type system.The main body of the continuous heaters of said type is promptly opened wide having on the edge of opening face of the aquaporin that jointly forms channel cavity usually on the edge surface with opening of each comfortable overall region on two wide.Be engaged with each other to edge of opening face and waterproof ground, lid marginal portion and wiper seal.Usually, between lid marginal portion and edge of opening face, be configured with bridged appearances with the interconnective sealing of adjacency channel opening.
Though main body is most than on width dimensions, extending more longways on the length dimension, length is than opposite on two sizes like this, and perhaps these length can equate at least basically.Main body is rectangular moulding mostly.It also can at least partly be circular.The main body front of main body is meant the face towards dry place all the time, and the main body back side is meant the face that deviates from dry place, and irrelevant with title, direction and/or the deployment scenarios of face continuous heaters or its shell.
Belong to the having of continuous heaters accessory of the known electricity of said type, form the main body of whole mid portion, this main body comprises wide that forms two end faces, with wide face separately along wide whole connection cover marginal portion on the docking site.End face forms the edge of opening face.End face is boundary and composition surface, its by on main body around seam limit, this seam is divided into the boundary seam on the different directions along main body side separately.These boundary seams correspondingly only are positioned on the long face with face titles of main body, and on the front of the complex that constitutes by main body and lid marginal portion and the back side boundary seam.Therefore, the interface that forms seam is parallel or identical with the edge of opening face, and this interface transverse to or perpendicular to aquaporin.The lid marginal portion leans against on the edge of opening face according to the mode of disk, and wherein, the boundary seam between body rim contact pin and the lid edge contact pin is only confirmed through the edge of the interface between lid marginal portion and main body.This boundary structure in enough sealings, sealing is up to specification and simple and stop the injection water still can not be satisfactory through the contact pin system aspects.In addition, the wiper seal and the water-stop of the described bridged appearances in edge also affect adversely, and perhaps involve special seal approach.The lid marginal portion is connected the butt joint that produces through screw mostly with main body and particularly receives bend loading.No matter be the sealing that produces the contact pin system, still produce passage and connect, all require sizable clamping force, this clamping force is applied on whole wide of main body, and this main body has a large amount of clamping positions.Whole around boundary contact pin broken off by perpendicular interface or interface, this causes the sealing between contact pin system and shell to go wrong.The bending stress that is in these faces of butt joint in cooperating the each other contact pin that can in boundary seam zone, cause demarcating is squinted each other, although skew is very little.For example this skew of the 1/10mm order of magnitude causes the blow-by property that can not put up with between free contact pin edge and shell.The consequence that this point causes in practice is; Along the height of main body increase around the quantity of sealing contact pin; And/or additional sealing mechanism is set, so that main body, cover wide and the housing of continuous heaters are fitted to each other under the acting in conjunction aspect the overall seal request and coordination each other.These measures particularly cause adverse effect to batch process.These measures involve cost, have but stayed sealing problem.Here, the present invention will provide auxiliary.
