Description
Technical field
The present invention relates to a kind of through type heater.
Background technology
In the known through type heater in DE4326353A, the shroud rim district of rectangle comprises the periphery of the housing back wall that same rectangle extends.Housing department below one forms the shroud rim district that has a shoulder, by the front side of this shoulder rest in the rear wall marginal zone.In one embodiment, form a double flute in the marginal zone of housing back wall, be placed on the buckle of cover in this groove and can compress this groove from the front.This fixed form is expensive on manufacturing technology.However, can not guarantee that the neither one user separates the violence of shroud rim district big like this by power, to such an extent as to arrive part main flow or that another is dangerous, because shroud rim district very long and straight extension can open under flexible effect at full tilt,, the shroud rim district submits to because only resisting such distortion and centre on the angle.
In the known water heater in DE10130610A, heater block comprises two interconnective drip moldings, and the rear wall of utensil is formed by following these drip moldings of drip molding, and water heater for example is installed on the vertical wall by means of this rear wall.Cover from the front as the crow flies by putting and being stuck.The heater block marginal zone have be arranged on general vertical plane, the plane of heater block in buckle, the cover that only in the visual field is arch is by means of snap fit.Inboard, shroud rim district has the recess that matches with buckle, and inboard groove is from the edge to the recess.The inboard in shroud rim district is by being placed on the heater block marginal zone of outside.Such connected mode is expensive on manufacturing technology.The installation and removal requirement of cover knows the installation principle and requirement is highly wholwe-hearted.This is dangerous, promptly user use force inadequately cover is separately wide so at least in part, to such an extent as to buckle unclamped or near internal part flowing water or heating.
Summary of the invention
Task of the present invention is, a kind of through type heater of mentioning when beginning is provided, and it uses simple by one, prevents from involuntaryly to open and prevent that into the reliable cover fixture of water realizes, do not need the fixing and seal means of adding.
According to the invention provides a kind of through type heater, have a heater block, the viewable side of this heater block is covered along the heater block marginal zone in a lid district at least by a cover of removably installing, and one of them shroud rim district closely surrounds the heater block marginal zone from the outside and fixes by at least one snap fit device.It is characterized in that heater block marginal zone and the shroud rim district shape in the lid district is a circle, an ellipse, or a rule bent limit or straight flange or irregular polygon; Cover is suspended at least one the hanging position place on the periphery of heater block in the mode of form fit; And cover at least one circumferential location radially relative with hanging position and fix by described snap fit device, to prevent rotation around hanging position.
Cover is preferred only to be fixed like this at hanging position and with at least one snap fit device, so that allows it not take off by force.Because cover must upwards turn over by the opposite that at first is suspended on heater block, cover preferably takes one to force down on the heater block to the rotation of final fixture, up to interlocking buckle fixture.Since hanging position, snap fit device and generally be circular, oval-shaped or polygonal marginal zone between cooperation, the marginal zone is surprising to be maintained fixed simply mutually, so that shroud rim be what deserves to be mentioned is and allowed no longer to separate.Because it is outwards sagging hardly to cover on a binding site, because cover is not the shape sealing ground support that links up along whole lid district.Should fixing base be circular basically,, compare that the shroud rim district fundamentally resisted such using force preferably with a straight marginal zone by this circle.And do not exist and cover on the danger of throwing off on hanging position or the snap fit device.At hanging position, a cover snap fit device that permission was said to the front is opened and is opened the direction of cover and upwards turns over.The snap fit device generally adopts as this area, is so reliable, to such an extent as to it is not destroyed under violence yet, especially needs suitably to unclamp a definite operation or an instrument.
The shroud rim district suitably outwards overarches to tilt or extend obliquely on the plane on the heater block marginal zone from viewable side.The base of the following improvement cover of this profile, i.e. the violence that this profile opposing comes from the heater block marginal zone separates and more resistance.
In the marginal zone is under the polygonal situation, and polygonal interior angle is greater than 90 degree, and formation cusped edge or fillet.Then, have with circle or oval-shapedly have same basically effect, because the marginal zone of cover supports oneself everywhere, and do not exist long and be straight " freedom " section, wherein Zhao wall energy is weaker enough slightly.
A kind of preferred embodiment in, at hanging position the extension tongue that at least one extends from the inboard in shroud rim district is set, hang the back that tongue is suspended on the heater block marginal zone.Hanging connection can use easily, and helps the base of fixed cover.In this case, advantageously, the hanging position in the running of through type heater and the installation is arranged on the top, thereby the permission cover is settled in the favourable mode of ergonomics and fixed.Hang tongue and can also be arranged on the heater block marginal zone, and be inserted in the recess of cover.
In another preferred embodiment, the shroud rim district outward-dipping extension on the heater block marginal zone in the lid district.Exceed by this, the shroud rim district keeps higher profile robustness, and the water spray sealing is enhanced, and the violence separating dissolve in shroud rim district.
Stable and prevent that reliably water spray from entering for the base that makes cover, can be suitably in the lid district of heater block marginal zone, and in the inboard in shroud rim district, be provided with pile together or the circumferential rib of aside catching mutually.These ribs help Steady base when fixed cover, and constitute a labyrinth sealing mode that prevents to spray water.
Consider a kind of utilization easily when cover is installed, advantageously, an alignment recesses is set, be used to insert a alignment protrusion, preferably in the zone of hanging position in the shroud rim district in the heater block marginal zone.When mounting cup, do not make the tangible sign that is covered with correct hanging position.In addition, that shape between alignment protrusion and the alignment recesses is interfered the violence that prevents to cover on the heater block or reverse unexpectedly, this is possible under circular or slightly circular situation.The position of alignment recesses and alignment protrusion also can be got wrong.
In the preferred implementation, cover has at least one buckle, forms a socket in heater block for this reason.This is used easily, because when cover is suspended on hanging position in good condition, arrives its destination when being buckled in the cover upset surely.
In this case, suitable is, buckle is arranged on the support of cover, and support is provided with a plug at least, and plug is inserted into the plug receptacle of a deep hole by socket, and is supporting the firm base of cover at bonding state.Dark limit fixture with useful effect can also be set in this zone, cover is fixed on a precalculated position accurately, particularly this shroud rim district is abutting on the heater block marginal zone under the general prestressing force.Select the prestressing force base of such cover, because consider the compensation of manufacturing tolerance, this is favourable.
Because cover at first is suspended on hanging position, and therefore because a rotation is inserted into its final position up at least one buckle, the socket that advantageously is used for buckle at least is provided with a buckle activity space, is used for such rotation.
If two buckles are set, and hanging position and buckle be when being arranged on the bight of isosceles triangle, and then Zhao position is highly stable.3 of forming cover by this way are fixing.Preferred this isoceles triangle shape for example drift angle is about 30 degree.
The noticeable impression of outward appearance that cover represents a kind of aesthetics, cover at least mainly forms spherical caps.The spherical caps form produces highly natural distinctive stiffening as ovum, particularly the violence in opposing lid district separately.Rib rib is not set in addition, because may hinder the shower heater that is installed in shower area.

The specific embodiment
The through type heater D that represents among Fig. 1 is the so-called bath heating device SH on for example a kind of face wall that is installed in shower area.Yet the cover fixation principle that describes below can also be suitable for for example through type heater or the little accumulator and the similar article of other family expenses just the samely.
Through type heater D shown in Fig. 1 comprises a heater block M, and this heater block for example is assembled by two synthetic material casting parts (Fig. 5), and the rear wall that shaped portion is configured for installing with this heater block.In this embodiment, have the viewable side that a cover H who is similar to a spherical caps shape is used to cover heater block M.Cover H (Fig. 1) is suspended on the hanging position E at heater block M place, and on the direction of arrow 1 around hanging position E as invert center towards following upset, snap in snap fit part V up at least one at the buckle 2 that shroud rim district RH is provided with, and shroud rim district RH is booked above the heater block marginal zone RM that is built up accordingly, when needing even above abutting in.For example, water outlet A down is set on heater block M.
As shown in Figure 2, shroud rim district RH and heater block marginal zone RM are circular basically, thus shroud rim district RH from viewable side to heater block marginal zone RM tilt and (Fig. 1) even for example the piece spare on cover stretch out.Forming a continuous lid district between marginal zone RM and RH, in an illustrated embodiment, is circular, and only interrupt in the zone below of through type heater D, for example water outlet A.
In embodiment shown in Figure 2, two buckles 2 are arranged on the support 19 of cover H.Hanging position E and two buckles 2 are placed on the angle (about 30 degree of drift angle) of isosceles triangle.Heater block H is formed for the socket 3 of buckle 2.On each support 19, form a plug 4, baffle plate for example, buckle 2 one latches, and plug 4 just is received near in the plug receptacle 5 of socket 3.In addition, for example dark limit fixture 6 is set, thereby, just cover is remained on the position of a qualification as long as buckle 2 is kept in good condition at plug 4 and plug receptacle 5 places.For cover H being taken again, for example in the heater block M that Fig. 1 represents, opening is set, by means of an insertion instrument or pin, buckle 2 allows to throw off.
Structure by means of the card address E zone between Fig. 4 to 6 couple of cover H and the heater block M is described.
According to Fig. 3 and 4, the inboard of shroud rim district RH is provided with one and hangs tongue 7, hangs tongue 7 and relatively is arranged on backward on the end of shroud rim district RH with anchor ring 10.In the inside of cover, aim at the center that hangs tongue 7, form an alignment protrusion 8.In addition, can form one in the inboard of shroud rim district RH and center on upwardly extending rib in side or lip 9, its purposes is described in the back.
Heater block M has neckline portion 13 in the marginal zone of a forming section 12 below at heater block marginal zone RM (Fig. 5 and 6), and neckline portion 13 is combined into heater block M with last forming section 11.The edge of last forming section 11 outwards is clamped in this neckline portion top.Stretch a plurality of for example concentric ribs 15,17,18 towards the viewable side that covers by cover H around heater block marginal zone RM.Another one alignment recesses 14 is formed on this zone, and this recess is suitable for inserting alignment protrusion 8.
As illustrated in fig. 1 and 2, the extension tongue 7 of at first retrousse cover H is broken away from edge 16, is suspended in the neckline portion 13 of 16 back, edge.In order correctly to locate, at first only alignment protrusion 8 is inserted in the alignment recesses 14.Then, hanging position E is used as invert center, thereby makes the be directed downwards upset of cover H at the arrow 1 of Fig. 1, be inserted in the socket 3 up to buckle 2, and plug 4 enters into plug receptacle 5, till dark limit fixture 6 works.Then, cover H is fixed.The cover H of circle be that size between the circular heater block marginal zone RM is suitably selected so equally, consequently cover H and have a slight prestressing force at Gai Qu and be applied on the RM of heater block marginal zone, and be close to thereon in whole lid district.This prestressing force fixedly is a kind of selection.It is cmpletely that cover H accurately forms suitably.
As clearly expression among the figure, cover H forms the spherical caps that has circular shroud rim district RH.This spherical caps is less than a hemisphere, thereby the cover wall tilts towards heater block marginal zone RM straight, and particularly, surpasses this zone even and stretch out.The rib 15,17,18 that is provided with in the heater block marginal zone roughly adapts to the trend in the inboard of cover wall when needed, thereby also forms a support effect there.The cover wall is important in the trend of a lid district or an inclination in the battery limits of heater block marginal zone RM, because be to be shaped separately, shroud rim district RM provides separately very strong opposing of violence.At least one circumferential rib 9 of RH inside, shroud rim district is positioned at for example rib 17 places of heater block marginal zone RH, perhaps even on this rib side push through, thereby produce the effective labyrinth sealing mode of spraying water of preventing, other rib 15,18 also participates in sealing with the inwall of cover.
Cover must not form spherical, though this is best form.It generally is circular or oval-shaped covering on that shroud rim district RH can form, or polygon bent limit or straight flange, however suitable be that each interior angle is greater than 90 degree.Then, heater block marginal zone RM is correspondingly made.
