Definitions
- the invention relates to a refrigerator, such as a refrigerator or freezer or the like, with a heat-insulating housing and at least one door, above which a hood-like cover is provided on the housing for receiving an electronic control or display elements or the like, which cover has at least one on its front side to this open and at least largely covered receptacle via which a pushbutton acted upon by an energy accumulator and held against the effect of the energy accumulator in the receptacle is led out of the cover.
- hood-like covers for accommodating display elements or else printed circuit boards equipped with electronic components are arranged on their doors, on which a pressure switch serving as a device switch is then usually fixed, which can be actuated via a push button which is led out of the cover and is accessible to an operator.
- the pushbutton is mounted in a receptacle provided on the cover and pressed into a defined operating position by a spring, the force exerted by the spring on the pushbutton being intercepted by a facing provided on the front of the cover and covering the receptacle, through which the push button is passed over an opening.
- the cover In order to be able to absorb the force exerted on the pushbutton by means of a spring through the cover, the latter must be designed to be dimensionally stable either by its design or by the choice of material.
- the necessary bending stiffness of the panel was achieved in the known embodiments either by a metal cladding profile or by a plastic profile with the appropriate material thickness.
- the cladding Profiles should also be provided with markings to represent the setting and device parameters, the printing of such veneer profiles with the corresponding markings is quite costly, since each of the veneer profiles must be printed in a single process.
- the markings are illuminated in order to make them easier to recognize for an operator, particularly in the case of veneer profiles made of metallic materials, which is extremely complex.
- the lighting of the markings is made easier by the choice of a translucent material, but it is relatively difficult to integrate the plastic facings with a pleasing design into the cover for reasons of rigidity with a relatively high material thickness.
- the invention has for its object to avoid the disadvantages of the prior art in a refrigerator according to the preamble of claim 1 with simple design measures and also to improve the assembly.
- the push button and / or the cover have means which cooperate when the push button is inserted into the receptacle and are able to hold the push button and the cover together against the action of the energy accumulator.
- the measure according to the invention supports the force introduced via the energy accumulator onto the pushbutton for the precise definition of its position exclusively on the statically sufficiently dimensioned components, namely the pushbutton on the one hand and the cover on the other hand, so that no forces are exerted by a covering covering the front of the cover housing are to be recorded, which results in the possibility of this veneer being produced, for example, from film material which can be printed inexpensively.
- the pushbutton is already fixed to the cover after its insertion into the receptacle without additional measures.
- the cover and the push button can be provided as a pre-assembled unit and can be obtained from a supplier, since the facing profile with the device-specific setting markings applied thereon no longer necessarily have to be a component of the pre-assembled module, but rather device-specific from the refrigeration device manufacturer can be attached to the refrigerator at an advanced stage of the manufacturing process.
- the means are designed as latching hooks which are able to cooperate with projections on the push button and / or the cover in a form-fitting manner.
- At least two locking hooks are provided, which are arranged at least approximately opposite one another.
- Such a measure not only prevents skewing of the pushbutton acted upon by the energy accumulator, but at the same time also ensures that the pushbutton does not jam in its starting position determined by the spring force and thus when the pushbutton is actuated, its smooth operation is guaranteed.
- connection between the pushbutton and the cover is particularly simple in terms of construction and manufacturing technology if, according to a next advantageous embodiment of the object of the invention, it is provided that the latching hooks are arranged on the pushbutton and interact positively with a projection on the cover.
- the projections are particularly easy to manufacture if, according to a further preferred embodiment of the object of the invention, it is provided that the projections are provided on the cup walls of the receptacle
- the projections on the hood-like cover are particularly robust and easily accessible if, according to a next preferred embodiment of the subject of the invention, it is provided that the projections are arranged on the walls of the receptacle outside of the space delimited by it and above in the floor through openings provided in the receptacle are accessible, upstream of which feed bevels along which the rash hooks are fed to the through openings.
- the through openings are preceded by bevels along which the latching hooks are fed to the through openings.
- the receptacle has shoulders projecting into its space in steps, which serve as depth stops for the displacement path of the pushbutton in the receptacle.
- the travel path limitation for the pushbutton ensures that the pressure switch, which is mounted on a printed circuit board, for example, is not damaged as a result of excessive force being applied to the pushbutton.
- a force accumulator is particularly easy to produce and at the same time can be accommodated in the receptacle of the cover if, according to a next advantageous embodiment of the object of the invention, it is provided that the push button is provided with a leaf spring serving as an energy accumulator, which is supported on the bottom wall of the receptacle.
- the assembly process of the push button to the receptacle is significantly simplified by the assignment of the leaf spring to the push button.
- the push button is made of injection molded plastic, to which the leaf spring is integrally formed.
- Fig. 1 shows a front housing in a simplified schematic representation in the area of a push button arranged therein, in horizontal section.
- Fig. 2 shows the front housing in plan view
- Fig. 3 cut the front housing according to the section line III - III.
- a hood-like cover 10 referred to as a so-called front housing, is shown, which is essentially U-shaped in cross-section and is fixed with the free ends of its legs 11 on the housing of a refrigerator or freezer, not shown, above the appliance door.
- the cover 10 also accommodates a printed circuit board 12 which carries a pressure switch 13 and which is fixed within the receiving space of the cover 10 by means of latching means 14 provided on the legs 11.
- the U-shaped cover 10 is provided on the outside of its base serving as the front wall 15 serving as a visible surface with a receiving region 16 which springs back in steps in relation to the outside.
- the recording is a bowl-shaped receptacle 17 with a rectangular cross-section, designed to be open towards the outside of the front wall 15 and extending towards the free ends of the legs 11, and shaped like a bowl.
- the 17 has a bowl space 18, the depth of which is limited towards the free ends of the legs 11 by a bowl bottom 19 which has an opening 20 in its center and which is provided with passage openings 21 at its edge sections.
- the bowl bottom 19 is connected to the lateral delimitation of the bowl space 18 with lateral bowl walls 22, of which the bowl walls which run essentially perpendicular to the legs 11 are provided with step-like projections into the bowl space 18, serving as a depth stop, opposite shoulders 23, the parallel to which Front wall 15 extending step sections serve as stop surface 24.
- the cup walls 22 arranged perpendicular to the legs 11 have feed bevels 25 which open into the through openings 21 and which have an inclined plane to the through openings.
- openings 21 are executed and which are not arranged directly opposite each other on these cup walls 22, but have a lateral offset to one another.
- the cup walls 22 aligned perpendicular to the legs 11 each have a projection 26 in the area of the passage openings 21, which has its free end directed towards the printed circuit board 12.
- the bowl space 18 of the receptacle 17 is used for introducing a pushbutton 27 which has an operating part 28 which is essentially in the form of a circular cylinder and which protrudes with one of its end faces with respect to the front wall 15 and on this end face with a lens-shaped part serving to operate the pushbutton 27 Cover 29 is provided.
- the operating part 28 has at its other free end two mutually opposite arms 30 facing the cup walls 22 equipped with the shoulders 23.
- each arm 30 is equipped in the vicinity of their free edge, on their underside facing the bowl bottom 19, with resilient latching hooks 31 which, when the pushbutton 27 is in the installed state in the receptacle 17, penetrate the passage openings 21 provided in its bowl bottom 19 and which run parallel to the bowl bottom 19 Hook portion engage behind the projections 26.
- a leaf spring 32 is fixed on the underside of each arm 30, which is supported with its free end in the installed state of the pushbutton 27 under pretension on the inside of the bowl bottom 19 facing the operating part 28 (see FIG. 2).
- the control panel 28 is also equipped with an actuating sleeve 33, which is arranged concentrically within the control panel 28 and projects with its free end relative to the control panel 28.
- the projecting end of the actuating sleeve 33 penetrates the opening 20 in the cup base 19 and is in engagement with the pressure plunger of the pressure switch 13.
- the operating part 28 penetrates an opening 35 made in a film-like, possibly translucent and printed with device setting markings and sits within the receiving area 16, the opening 35 being at least largely matched to the diameter of the operating part 28.
- the operating part 28 passing through the opening 35 projects with the cover 29 serving for its operation in relation to the cover 34 covering the receptacle 17 which is open at the front. Due to the receptacle 17 which is open on the front prior to the assembly of the panel 34, the pushbutton 27 can also be inserted into the receptacle 17 after the circuit board 12 has already been assembled.
- the extension arm 30 determines which, with their free, Gungshülse 33 opposite ends are able to slide along the inner sides of the cup walls 22 equipped with paragraphs 23.
- the latching hooks 31 are fed to the through-openings 21 via the feed bevels 25 and penetrate them before they engage the projections 26 with their sections running parallel to the arms 30.
- the leaf springs 32 which are supported on the bowl bottom 19 under pretension, exert a pretensioning force on the pushbutton 27 which is latched on the cover 10 by means of their latching hooks 31.
- the actuation stroke of the pushbutton 27 is limited by the interaction of the stop surface 24 with the underside facing it on the brackets 30, as a result of which the force that can be exerted by an operator on the pushbutton 13 via the pushbutton 27 is limited and damage to the pushbutton 13 is thus avoided is.
- Thermoplastic materials which can be processed in the plastic injection molding process have proven particularly suitable for producing the cover 10 and the pushbutton 27.
