Both housing components are a one-piece, rectangular box (K), open at one end with a rectangular lid covering the box opening with a height amounting to only a fraction of the height of the box.

Description

hot water storage

The invention relates to a hot water store, in particular a small hot water store of the type specified in the preamble of claim 1 .

In the known small hot water storages in practice, that is to say in the hot water storage with the back of the housing of the small storage mounted on a substantially vertical wall in the installed state, there are generally two different housings design method. The basic feature of a housing design method is to use a rectangular shallower box, its box bottom is used as the installation rear wall, and the internal components of the small storage are installed inside the box from the open side, and then plugged in from the front A second similar shallower cabinet. The box body edge of the second box body can be inserted into the opening of another box body, and can also cover its outside. In the installed state, the interface between the two cabinets is basically vertical. In another known housing design method, the internal components of the small storage unit are installed in a rectangular box profile made of sheet metal running vertically in the installed state, one side of the box forming the rear installation wall , and then put on the upper and lower plastic covers, and they engage the two open ends of the box body profile that the metal plate is made from the outside on the two substantially horizontal interface. These two known shell design methods make the production cost and installation cost relatively high in order to at least ensure that the boundary seam will not spray out as much as possible, so the price is also relatively high. They also have deficiencies in the shape design of the product. In the first design method, the transition area between the box plugged in at the front and the box at the rear, i.e. the box that constitutes the installed rear wall, and the box mainly made of another and apparently different material Body is always obvious. In the second design approach, the mixed structural form with plastic and metal sheets with two parting joints is also evident due to the apparent difference in surface characteristics and surface flatness. In addition, it is difficult to ensure the ability to prevent water spray at the lower boundary seam. However, the serious disadvantage of these two design methods for sales strategy is that using these two design methods has no obvious freedom for the type of model series based on the same or similar internal components of small memories. degree, i.e. distinct distinctions can be obtained without significant expense. However, manufacturers of this small memory have such a market strategy requirement, that is, different product models designed for different sales locations can be targeted to meet specific customer groups, and in the same product series, they can Offer products at different price points for sale, such as selling simplified products in the construction market, and selling value-added products in professional houses.

The object of the present invention is to provide a hot water storage, in particular the small storage mentioned at the outset, which adopts an easily cost-optimized design of the housing, which can be obtained without much additional expenditure. Eye-catching appearance, and this appearance design can be significantly changed according to the starting point of market strategy.

The features described in claim 1 achieve the above object.

A simultaneously aesthetically pleasing appearance can be provided economically by a quadrangular tank like a quadrangular bucket and a cover which closes the opening of the tank with an essentially horizontal dividing seam. This design approach also reduces production costs and simplifies the installation process. There need not be clearly visible material and surface differences between the cover and the case, and the cover and case are preferably made of the same material. The internal contours of the box and cover are basically the same for all product variants. There is considerable freedom in the design of the outer surface or profile, allowing for distinctly different profiles. For example, a product model sold on the construction market can have a simple box and a simple cover, while a value-added version of the product model sold in a professional firm has an external high-end box and cover, that is, an expensive shape design.

In a suitable embodiment, in the installed state of the hot water storage tank, its tank should be located below, and the cover closes the upper opening of the tank in the area of the parting seam. The rear wall of the cabinet is used as the installation rear wall, so that there will be no visually unpleasant transition part between the installation rear wall and the side of the housing.

The box and lid may be separate plastic moldings, preferably connected to each other by at least one hinge or other connecting mechanism. Because the two are manufactured separately, each shell part can be made into different styles according to people's expectations, and there are many different combinations of building blocks.

In a preferred alternative, the box and the lid are formed as a one-piece molded part, in particular a plastic molded part, and are connected to each other and can be opened and closed by at least one integrated leaf hinge. In this design solution, the cover and the box appear as one casting.

This method of designing the housing and cover has the further advantage that the greatest possible protection against water jets in the region of the parting joint can be achieved with simple technical means. For example, a sealing structure is designed on the boundary seam, which plays a good sealing role when the cover is normally closed. For example, a groove/key (Feder) structure or a labyrinth seal structure can be used, which can be taken into account in the forming and manufacturing of the box body and cover. Elastic seals can also be added to enhance the sealing effect.

Advantageously, the cover can be locked inside the housing opening, preferably using snap-in elements or hooks. The locking mechanism is not visible from the outside, but it prevents some improper access to the inside of the case. In order to be able to remove or open the cover, preferably corresponding openings (Zugriffsöffnung) will be designed on the housing and/or the cover, through which the locking element is opened by means of a tool or the like.

Applying this design method, it is also easy to set the water pipe interface of the small hot water storage on the cover, or lead it out through the cover. Especially when the cover is opened and removed in the direction in which the connection extends.

Preferably at least one operating element of the compact memory is arranged on the cover. The shaping of the lid required for this can be realized during the shaping of the lid.

If, in the installed state, the cover has a front (frontseitig) bevel, which extends obliquely from the cover top surface to the boundary seam, and the bevel is designed as the operating area of the at least one operating element, then the small storage device will be affected during use. It will be quite comfortable to operate. Furthermore, such a bevel is also a visually noticeable difference. Such bevels can be omitted in other product models, and this product is just completely different in appearance.

Alternatively, the operating area can be arranged on the front of the box, preferably extending to the front of the cover. This is another product model with a completely different shape. Basically, as an obvious distinguishing mark, the dividing seam can be emphasized visually, or it can be made to disappear as much as possible. This can be realized simply in terms of shaping technology with the design method of the box and cover.

Embodiments of the subject matter of the present invention are described below in conjunction with the accompanying drawings, wherein:

A schematic perspective view of a first embodiment of the compact memory of Fig. 1;

The perspective oblique view of the second embodiment of Fig. 2 compact memory;

Figure 3 Part of the side view of the embodiment of Figure 1

The compact memory S of the first embodiment shown in FIG. 1 has a case G for housing internal components of the memory (not shown). The housing G consists of, for example, a plastic, substantially quadrangular, top-open box K and a cover D, also made of plastic, which closes the top opening of the box K. The parting seam between cover D and housing K is at least as far as possible horizontal in the installed state shown in FIG. 1 . Both the box K and the lid D are in one piece, in some cases they can even consist of a single plastic molded part, connected by an integrated thin-plate hinge 17 (FIG. 3). The box body K has left and right sides 1, 3, a front wall 2 and a back wall 4, and the back wall 4 is the installation back side simultaneously, and has corresponding fixing device 11 (Fig. 3). The bottom 5 of the box K is closed, so that the box K is generally a quadrilateral barrel with an open top. The cover D has a top surface 7 that is as flat as possible or slightly arched and a front bevel 8 that extends to the parting seam 6 . The ramp 8 delimits an operating area 10 on which at least one operating element 11 of the compact memory S is arranged. For example, a water connection 9 can be provided on the cover D, for example in a molded sleeve. The lid D and the case K are openably and closably connected, such as being turned sideways upwards or rearwards upwards, wherein the hinge 17 is installed in the connection area ( FIG. 3 ). There are two possible options here, the cover D can be installed completely detachable, and snaps onto the opening of the box K on the upper undercut or engages in the undercut of the opening (in the latter case, the dividing seam is visually obscured live or disappear).

In another embodiment shown in FIG. 2 , the cover D has a flat top surface 7 and a vertical front surface 18 . The two vertical edges of the housing G, that is to say the edges laterally delimiting the front side 18 of the box K and the cover D, are chamfered or rounded in the area 8 ′. The operating area 10' has an operating element 11 on the front side 2 of the housing K and extends preferably to the top side 7' of the cover D, ie through the front side 18 of the cover D.

The parting seam 6' is barely visible here. The cover D can be inserted into the upper undercut of the box K so that the parting seam 6 ′ is not visible laterally from the outside. In FIG. 2 the cover D is connected to the case K by at least one leaf hinge or mounted hinge 17 and can be opened and closed or completely removed.

FIG. 3 shows a sealing structure 12 in the region of the parting seam 6, which is preferably integrally formed in the box K and/or cover D. As shown in FIG. For example, the sealing structure 12 may be provided with a groove/key insertion form, as shown in the groove/key elements 13 and 14 in the figure. Under certain circumstances, an elastic seal can also be provided in this region. It can also be designed as a labyrinth sealing structure formed by the cooperation of the cover D and the box body K.

In Fig. 3, the cover D is connected with the box body through a sheet hinge or an installed hinge 17, and can be opened and closed. As shown in the figure, the flap hinge or hinge 17 can be located as far as possible on the inside, so that when the lid D is opened, the rear edge of the lid protrudes too much from the rear side 4 . In a simple embodiment, the box K can be provided with an insertion slot for a corresponding element of the cover D in the interior of the opening area. The cover D can suitably be locked in the area of the sides 1 , 3 and/or the front 2 by means of the clamping elements V and the housing K to prevent certain unauthorized openings. For example, hooks 15 can be used, and openings 16 can be opened, for example by means of a tool, to open the respective jaw element V and thus the cover D. FIG.
