Definitions
- the invention relates to a hot water tank, in particular a small tank of the type specified in the preamble of claim 1.
- a shallow box with a rectangular outline is provided, the box bottom of which serves as an assembly rear wall and in which the small storage unit internal parts are mounted from the open side before a similar, shallow second box is attached from the front.
- the box edges of the second box are either inserted into the opening of the other box on the inside or put over them on the outside.
- the parting line is essentially vertical in the installed position.
- the inner parts of the small storage tank are inserted into a square box profile made of sheet metal, which runs vertically in the installed position, of which one side wall forms the rear wall of the assembly, and then upper and lower plastic slip covers are placed, which are in two in Grip essentially horizontally oriented parting planes outside over the opening ends of the sheet metal box section.
- These known housing concepts require relatively high manufacturing and assembly costs, also in order to achieve an at least largely splash-proof joint, and are expensive.
- the external appearance leaves something to be desired.
- the transition from the front plug-on box to the rear box, which forms the rear wall of the assembly, and which mostly consists of a different and also superficially different material, is clearly perceptible.
- the mixed plastic / sheet metal construction with the two parting lines is also clearly noticeable due to the significantly different surfaces and surface flatness.
- the splash water resistance in the lower parting area is difficult to ensure.
- a serious disadvantage in terms of sales strategy for both housing concepts is that the housing concepts do not offer any significant degree of freedom in versions of a model series based on the same or similar internal components of the small storage tank, without providing clearly recognizable differences without considerable cost.
- the invention is based on the object of specifying a hot water storage tank, in particular a small storage tank, of the type mentioned at the outset, which has an inexpensive housing concept which can be used to achieve an appealing external appearance without any appreciable additional outlay, and the appearance can be varied in a distinctive manner with regard to market-strategic aspects is.
- the square box similar to a square bucket, and the lid that closes the opening of the box with an essentially horizontal parting line, can be used to create a pleasing external appearance at low cost.
- the concept enables reduced manufacturing costs and simple assembly. There need be no clearly visible material and surface differences between the lid and the box.
- the lid and the box are preferably made of the same material.
- the inner contours of the box and the lid are essentially the same for all model versions.
- the outer surfaces or the outer design can, however, be modified with a wide degree of freedom in such a way that clearly different external appearances are produced.
- a model version sold through hardware stores can have a simple box and a simple lid, while a model version sold, for example, by specialist dealers can have an externally higher-quality box and a higher-quality lid, or a more complex external design.
- the box is located at the bottom in the installed position of the small store, while the cover closes the opening at the top in the parting area.
- the rear wall of the assembly is formed by the rear wall of the box, without a transition from the rear wall of the assembly to the side walls of the housing that would be visually uncomfortable.
- the box and the lid can be separate molded plastic parts and, preferably, are connected to one another by at least one hinge or another connecting mechanism. Thanks to the separate production, each housing component can be designed as desired, and many combinations are possible in modular form.
- the box and the lid are combined in a one-piece molded part, in particular a plastic molded part, and are connected to one another in a foldable manner by at least one integrated film hinge.
- This is a housing concept within which the lid and the box appear to be made of one piece.
- the housing concept with the box and its lid also offers the advantage of being able to achieve extensive splash water resistance in the joint area with simple technical means.
- a sealing structure is provided in the parting line, which is effective when the lid is properly closed.
- a tongue and groove structure or a labyrinth seal structure is already taken into account when the box and lid are formed.
- elastic sealing elements can also be incorporated.
- the lid can be locked inside the box opening, preferably by means of locking elements or snap hooks.
- the locking mechanism is not visually perceived on the outside, but prevents improper access to the inside of the housing.
- corresponding access openings are preferably provided in the box and / or cover, through which the locking elements can be released by means of a tool or the like.
- the water connections of the small storage tank can simply be arranged in the cover or led through the cover to the outside, in particular when the cover is opened or removed in the direction in which the connections extend.
- At least one control element for the small store is preferably arranged on the cover.
- the design of the lid required for this can be realized when it is shaped.
- the small storage device is easy to use when operating the cover if the cover has a bevel on the front in the installed position, which slopes from the top of the cover to the parting line and is designed as a control panel with the at least one control element.
- the bevel is a visually clearly distinguishable distinguishing feature.
- the bevel can namely be omitted in another model version, which then looks completely different on the outside.
- control panel can be arranged in the front of the box, and preferably extend into the front of the lid. This enables a different, typical appearance for a different model version to be realized.
- the parting line as a clear distinguishing feature can either be highlighted or largely made to disappear. In terms of shape, this is easy to achieve with the housing concept with the box and the cover.
- FIG. 1 is a schematic perspective view of a first embodiment of a small memory
- Fig. 2 is an oblique perspective view of a second embodiment of a small memory
- FIG. 3 shows a part of a side view of the embodiment from FIG. 1.
- a first embodiment of a small store S shown in FIG. 1 has a housing G for accommodating small store inner parts (not shown).
- the housing G consists of a box K which is quadrangular and open at the top, for example made of plastic, and a cover D which closes the opening above the box K, likewise made of plastic.
- the parting plane between the lid D and the box K is at least largely horizontal in the installation position shown in FIG. 1.
- the Cas- Like the cover D ten K is in one piece, if appropriate the cover D and the box K are even combined in a one-piece plastic molded part and connected to one another via integral film hinges 17 (FIG. 3).
- the box K has left and right side walls 1, 3, a front side wall 2 and a rear side wall 4, which at the same time is designed as an assembly rear side and has corresponding fastening devices 11 (FIG. 3).
- the bottom 5 of the box K is closed, so that the box K as a whole is basically a square bucket which is open at the top.
- the lid D has a largely flat or slightly curved upper side 7 and a bevel 8 on the front, which extends to the parting line 6.
- the bevel 8 defines a control panel 10 in which at least one control element 11 of the small memory S is arranged.
- water connections 9 are provided in the cover D, for example in molded bushings.
- the lid D can be hingedly connected to the box K, for example laterally upwards or backwards upwards, with hinges 17 being mounted in the connection area (FIG. 3). It is alternatively possible to attach the cover D completely detachably and to put it over an upper fold around the opening of the box K or to insert it into an upper fold (in the latter case, the parting line would be optically concealed or made to disappear).
- the cover D has a flat upper side 7 and a vertical front side 18.
- the two vertical edges of the housing G which laterally delimit the front side of the box K and the front side 18 of the cover D are in regions 8 'rounded or beveled.
- the control panel 10 ' is arranged with the control element 11 in the front 2 of the box K and preferably extends to the top 7' of the lid D, i.e. also over the front 18 of the lid D.
- the parting line 6 ' is barely visible here.
- the cover D could also be inserted into an upper fold of the box K, so that the parting line 6 'cannot be seen from the side from the outside.
- the lid D is hingedly connected to the box K in FIG. 2 via at least one film hinge or inserted hinges 17, or it can be removed completely.
- FIG. 3 shows a sealing structure 12 in the region of the parting line 6, which, preferably, is integrally molded into the box K and / or the cover D.
- a tongue and groove engagement can be provided in the sealing structure 12, as indicated by the tongue and groove elements 13, 14.
- an elastic seal is also provided in this area.
- a labyrinth seal could also be formed by the interaction of the cover D with the box K.
- the lid D is hinged to the box K in FIG. 3 via a film hinge or a mounted hinge 17.
- the film hinge or the hinge 17 could also be placed further inside than shown in order to avoid that when the cover D is opened the rear edge thereof protrudes too far beyond the rear side 4.
- the box K in the opening area could have an insert pocket for a corresponding attachment on the lid D.
- the lid D is expediently locked in the area of the side walls 1, 3 and / or the front wall 2 with the box K via locking elements V against unauthorized opening, e.g. by means of snap hooks 15, an access opening 16 enabling the respective locking element V to be released to open the cover D, for example by means of a tool.
