Definitions

• the present invention relates to a housing for a household appliance with a body and a lid which can be fastened to an opening of the body by a first detent surface of the lid engages behind a second detent surface of the body.
• Object of the present invention is therefore to provide a housing for a household appliance with a body and a lockable on the body lid, in spite of any inaccuracy or deformability of the lid and body secure locking of the lid and body is guaranteed.
• the object is achieved in a housing having a body and a lid which can be fastened to an opening of the body by a first detent surface of the lid engages behind a second detent surface of the body, that of the cover and the body in each case one of a recess and the another has a projection, wherein projection and recess mesh with a game in a direction parallel to the latching surfaces, which is smaller than the extension of the locking surfaces in said direction.
• the distance from the projection and recess of the locking surfaces can be made as small as necessary, so that manufacturing tolerances of this distance or deformability of lying between the projection and recess on the one hand and the locking surfaces on the other hand portion of the lid can not jeopardize the catch; the remaining area of the lid may be deformable or generously tolerated without affecting the safety of the latch.
• the body and lid have contours which are insertable into one another in a first orientation of the lid to the body and in the inserted state allow a pivoting movement of the lid in a second orientation, through which the locking surfaces lock together.
• the interlocking contours also define an axis of pivotal movement.
• the contour formed on the lid is a bulge
• the contour formed on the body is an undercut, in which the bulge is insertable.
• An axis for the pivotal movement of the lid can be easily defined by the engagement of the contours of the body and lid together.
• the two contours overlap in the direction parallel to the locking surfaces on a length which is greater than the game, with the projection and recess in this direction interlock.
• the engagement of the contours in each other can not be lost when the lid shifts in relation to the housing in the context of the game between the projection and the recess.
• the inventive idea further provides that projection and recess have a smaller distance to the locking surfaces than to the two contours.
• the portion of the lid between the projection and recess on the one hand and the latching surfaces on the other hand thus has smaller dimensions than the portion between the projection and recess on the one hand and the interlocking contours on the other. Therefore, the former portion can be manufactured with comparatively tight tolerances, and it is sufficient for a small overlap between the locking surfaces to ensure a secure locking.
• the body and lid each have a plurality of locking surfaces on opposite edges of the opening; this allows a locking of the lid by simply plugging on the opening.
• At least one of the lid and the body has a plurality of staggered latching surfaces.
• the latching surface of the other of the cover and the body engages behind one of this plurality of staggered latching surfaces, the lid can be locked in different positions to the carcass.
• the latching surface of the lid is elastically displaceable in a tangential to her direction.
• the latching surface of the lid can thus be easily passed to the latching surface of the body when mounting the lid on the body.
• the projection may be formed as a rib and the recess as a groove. In this way, the displaceability of the lid on the body is limited in opposite directions.
• the groove has a widened input area.
• the insertion of the rib in the groove is facilitated.
• FIG. 1 is a perspective view of a refrigerator, in which a housing according to the invention is installed.
• FIG. 2 shows a section through a part of a body and through a lid of the housing according to the invention in a first orientation, in which the lid engages pivotally in the body.
• Fig. 3 is an enlarged view of details of Fig. 2;
• FIG. 4 shows a representation analogous to FIG. 3 in a second orientation, in which the body and the lid are latched to one another;
• Fig. 5 is an analogous to Fig. 3 representation according to a second embodiment of the invention.
• FIG. 1 shows a perspective view of a refrigerator, such as a stand-alone refrigerator or freezer with a body 30 and a door 31.
• the top of the body 30 is formed by a worktop 32, the front edge 33 is flush with the door 31.
• an opening is broken, in which a body 1 of a housing is inserted.
• the body 1 has approximately the shape of an elongated cuboid with an open front.
• a cover 2 of the housing is shown separated from the refrigerator. It comprises a cover plate 14, which covers the front edge 33 of the worktop for the most part in the mounted state, and an apron, the four of a back of the cover 14 at right angles projecting, mutually connected at corners webs 15, 16, 17 (see also Fig. 2 ) and is provided to engage in the assembled state in the body 1.
• Body 1 and lid 2 are injection molded from plastic.
• the housing formed by body 1 and lid 2 is provided to receive control circuits of the refrigerator and to shield them from insulation material which substantially completely fills the hollow walls of the appliance body 30 and the worktop 32 outside the housing body 1.
• the lid 2 breakthroughs or windows may be formed at appropriate locations through which Controls the control circuits led out or display elements are visible; they are not shown in the figure.
• FIG. 2 shows a section through the cover 2 and the body 1.
• the sectional plane extends in the longitudinal direction of the body 1 and the lid 2, so that one of the two extending on a longitudinal side of the lid 2 webs 17 and a wide side wall 18 of the body 1 in plan view and extending on the narrow sides of the lid 2 webs 15, 16 and narrow side walls 19, 20 of the body 1 can be seen in section.
• End portions of the body 1 and cover 2 are - in the same orientation to each other as in Fig. 2 - shown in Fig. 3 enlarged.
• a detent 3 adjacent to the open front of the body 1 in the interior thereof.
• the detent 3 has a remote from the open front locking surface. 4
• a complementary to the locking lug 3 locking lug 5 is formed on an outer side of the web 16 of the lid 2.
• the locking lug 5 has, as can be better seen in the enlarged view of FIG. 3, a stepped contour with a plurality of each of the cover plate 14 facing locking surfaces. 6
• the two locking lugs 3, 5 is at least one elastically displaceable in the longitudinal direction of the body 1 and the lid 2 elastically.
• a tongue can be cut free from the side wall 19 or the web 16, at the free end of which the catch nose 3 or 5 is placed.
• the tongue is cut free in the web 16, since a corresponding free cut in the side wall 19 would impair the tightness of the body 1 with respect to insulating material surrounding it.
• an undercut 7 is formed, into which, as shown, a formed on the web 15 of the lid 2 pin 9 can be inserted.
• a step with a sharp edge 22 is formed on a side facing away from the open front of the body 1 surface 21 of the undercut 7 . This touched by the pin 9 edge 22 defines a for Section plane of Figures 2, 3 vertical axis about which the cover 2 with respect to the body 1 is pivotable.
