Description

Hot water reservoir

The present invention relates to a kind of hot water reservoir, particularly a kind of small-sized hot water reservoir of the type that in the preamble of claim 1, illustrates.

In the known in practice small-sized hot water reservoir, just under installment state, the shell back side of small-sized memory is installed in the hot water reservoir on the vertical substantially metope, two kinds of different shell methods for designing are generally arranged.A kind of basic characteristics of shell method for designing are, use the more shallow casing of a rectangle, as rear wall is installed, and at box house the inner member of small-sized memory are installed by open side at the bottom of its case, plug second similar more shallow casing then from the front.The casing edge of second casing both can insert among the opening of another casing, also can cover the outside at it.In installment state, the interface of two casings is vertical basically.In another kind of known shell method for designing, in the inner member of small-sized memory the is installed in tetragonal box outline that a metallic plate is made, capwise under installment state, a side of casing forms installs rear wall, load onto up and down plastics cover cap then, they engage two openends of the box outline that metallic plate makes from the outside on the interface of two basic horizontal.These two kinds of known shell methods for designing are in order to guarantee the boundary seam at least as much as possible and can not spray water out and make production cost relative with installation cost higher, thereby its price is also expensive.They are also having weak point aspect the configuration design of product.In first kind of method for designing, the casing from the casing plugged previously to the back promptly constitutes the transitional region between the casing that rear wall is installed, and mainly always conspicuous by casing other and that surperficial visibly different material is made.In second kind of method for designing, have the employing plastics of two boundary seams and the mixed structure form of metallic plate, because surface characteristics is obviously different with surface smoothness, also be conspicuous.Be difficult to guarantee down the ability of spraying water and taking place of preventing at boundary seam place in addition.And for these two kinds of methods for designing, it is for the wretched insufficiency part on the sales tactics, use these two kinds of methods for designing for type based on the range of models of the inner member of identical or similar small-sized memory, do not have the tangible free degree, promptly not significant cost just can significantly be distinguished.And there is the demand on such market strategy in the manufacturer of this small-sized memory, different product type for the design of different selling spots can satisfy specific customer base at ground to some extent exactly, and in identical product series, can provide the product of different prices to sell, simplify the version product such as in construction market, selling, then sell value-added product in professional firm there.

The purpose of this invention is to provide a kind of hot water reservoir, particularly start the small-sized memory of mentioning, it adopts a kind of shell method for designing that is easy to realize cost optimization, this method need not a lot of additional spendings just can obtain noticeable profile, and this configuration design can change significantly according to the market strategy starting point.

Feature described in the claim 1 has realized above-mentioned purpose.

Just can provide outward appearance simultaneously attractive in appearance by the quadrangle casing of a similar quadrangle bucket and with this casing opening economically with the lid that substantial horizontal boundary seam seals.This method for designing has also reduced production cost, has simplified installation process.Between lid and the casing obvious visible differences in materials and surperficial difference needn't be arranged, preferably make lid and casing with same material.For all product types, the in-profile of casing and lid is all basic identical.Outer surface or configuration design then have sizable free degree, thereby make to have visibly different profile.Such as simple casing and simple lid can be arranged for product sold model on the construction market, the product type of the increment version of selling in professional firm then has outside senior casing and lid, the configuration design of a costliness just.

In a suitable embodiment, under the installment state of hot water reservoir, its casing should be positioned at the below, and covers in boundary seam zone the closure of openings above the casing.The casing rear wall makes on the shell from rear wall being installed to the transition portion that just can not occur the side visually making us unhappy just as rear wall is installed.

Casing and lid can be independent plastics forming spares, preferably interconnect by at least one hinge or other bindiny mechanisms.Because both make separately, each case member can be made different patterns according to people's expectation, and multiple cordwood different compound mode is arranged.

Casing and lid are single-piece drip molding, particularly plastics forming spare in the preferred alternative, and interconnect and can folding by at least one integrated foil hinge.In this design, lid and casing just seem as same foundry goods.

The method for designing of this casing and lid also has another advantage, just can realize boundary seam zone blowout prevention water-based as much as possible with simple technical method.Such as sew on a kind of hermetically-sealed construction of design in boundary, it plays good sealing function at lid when normally closing.Such as can using groove/key (Feder) structure, or the labyrinth packing structure, they just can take in the shaping manufacturing of casing and lid.Also can add the effect of elastic sealing element enhanced leaktightness.

Advantageously, cover in the casing open interior and can lock, preferably use clamping element or grab.Can't see locking mechanism from the outside, but it some incorrect situations that enter enclosure have been prevented.In order to take off or open lid, preferably will and/or cover corresponding open mouthful (the Zugriffs ffnung) of design at casing, open locking element by means of instrument or analog by opening mouth.

Use this method for designing, also be easy to the waterpipe jointing that small-sized hot water reservoir is set covering, perhaps it is drawn by outwards covering.Particularly when lid is opened and is taken off on the direction that interface extends.

Be preferably in and cover the executive component that small-sized memory is set at least.Moulding to this required lid can realize in lid is shaped manufacturing.

If in installment state, be stamped positive (frontseitig) inclined-plane, it tilts to extend to the boundary seam from hd top face, and inclined design is the operating area that described at least one executive component is arranged, so in use will be quite comfortable to the operation of this small-sized memory.In addition, such inclined-plane also is the difference part that obviously can discover visually.Can cancel such inclined-plane in other product type, this product is just different fully in shape.

For another kind of scheme, operating area can be arranged on the casing front, and it is positive preferably to extend to lid.Be exactly the diverse profile of another kind of product type like this.Basically, the boundary seam both can visually be emphasized as a tangible diacritics, also can be made its disappearance as much as possible.This can be with realizing simply on the method for designing forming technique of this casing and lid.

Below, the embodiment of theme of the present invention is described in conjunction with the accompanying drawings, wherein:
