Abstract

The invention relates to a household appliance comprising a housing enclosing an inner chamber and at least one beam (25) which can be mounted in an engaging manner in a first and a second recess of the opposite-lying first and second walls of the inner chamber. At least the first recess is part of a groove (42) which is formed in the first wall. A flexible detent projection (40) engages in the groove (42) and blocks a first end of the beam (25) from moving from the recess along the groove (42) and can be displaced out from the groove (42) by moving the first end along the groove (42) towards the recess.

Description

household appliance

The present invention relates to a cabinet-like household appliance having a housing surrounding an interior space and at least one strut, which is mounted engaging in a first and a second recess of opposing first and second walls of the interior, wherein at least the first recess part of one in the first wall formed groove.

Known household appliances of this type are, for example, refrigerators with shelves in the form of a grate, which is formed by two extending in the transverse direction of the housing wire struts and wire struts interconnecting longitudinal wires, the wire struts engage in horizontal grooves in the side walls of the housing.

These struts, or the shelves to which they belong, may generally be pulled out of the grooves forwards without appreciable resistance, so that they are not suitable for attaching thereto fixtures to which forces parallel to the grooves in use become.

There is therefore a need for a household appliance that allows secure attachment of such components.

The object is achieved in that in a household appliance with a housing surrounding an interior space and at least one strut, which is mounted engaging in a first and a second recess of opposing first and second walls of the inner space, wherein at least the first recess part a groove formed in the first wall, in the groove engages a flexible latching projection which blocks a movement of a first end of the strut out of the recess along the groove and by a movement of the first end of this strut along the groove to the recess out of the Groove is displaceable. The strut is thus easy to assemble, but it is in the assembled state by a force opposite to the mounting direction force not easily detached from its mounted position. If the recesses on both walls of the interior are each parts of mutually parallel grooves, the assembly of the strut can be done by parallel displacement along the grooves.

According to a preferred embodiment, the strut is pivotable about the second recess as the center, and the latching projection is displaceable out of the groove by a pivoting movement of the strut, which has the second recess as the center.

In order to minimize the likelihood that other internals of the interior hinder the pivoting movement of the strut, the groove is preferably oriented substantially horizontally.

The first recess is preferably provided at a closed longitudinal end of the groove, so that a single locking projection is sufficient to hold the first end of the strut in the recess substantially immovable.

The latching projection may be formed by an engaging in the groove flexible tongue with a recess facing the free end. When the groove is bounded by two substantially parallel ribs projecting from a vertical wall surface, the tongue may conveniently be formed by a portion of one of the ribs unconnected to the wall surface.

For stiffening, at least one of the ribs may have a corrugated course.

The recesses and the groove may be formed on moldings, which in turn are mounted on walls of the housing.

In order to hang a built-in tilt-proof, at least two struts are suitably provided. Recesses for these two struts can be advantageously formed on a same molding.

To secure the built-in part of the strut, it may be provided with a form-fitting embrace the elastic hooks. In particular, the built-in part may be a frame in which a container is held out.

According to a preferred application of the invention, the built-in part is an ice maker.

In this case, the container may be a Eisstückformbehälter or a container for ice cubes.

If necessary, the collecting container is arranged below the Eisstückformbehälters.

In order to remove finished pieces of ice from the ice-forming container, the latter is preferably between a first position in which mold recesses of the Eisstückformbehälters are open at the top and in which filled into the mold recesses water can freeze therein, and a second position rotatable in which the mold recesses down are open.

If the frame is housed in a closable compartment of a compartment of the interior, the flap expediently has a recess through which the container in the closed position of the flap can be pulled out. Thus, on the one hand, the handling of the container is simplified and accelerated because an opening and closing of the flap is eliminated; on the other hand, the compartment receiving the frame remains protected from heat and moisture by the flap.

In order to minimize the passage of warm air at the recess of the flap, the frame of the ice maker preferably has a front plate, which is opposite to the flap in the closed position of the flap and thereby covers the recess.

In order to facilitate the handling of the pull-out container, this is preferably provided with a handle which projects in the assembled position of the container via the front plate of the frame into the recess.

A knob of the ice maker, which serves to rotate the Eisstückformbehälters, is also expediently by a recess of the flap through closed flap accessible. Thus, the finished pieces of ice can be removed from the mold without opening the flap.

This knob preferably engages a first longitudinal end of the

Eisstücksformbehälters, and the freedom of movement caused by the rotation is limited by a cooperating with the opposite second longitudinal end of the Eisstückformbehälters contour.

To solve finished pieces of ice from the Eisstückformbehälter, the latter is preferably elastically deformable by a torque acting on the knob.

In order to facilitate the filling and repositioning of the Eisstückformbehälters in the ice maker, the Eisstückformbehälter is preferably rotatably suspended in a frame which is pulled out of the frame together with the Eisstückformbehälter.

Further features and advantages of the invention will become apparent from the following description of embodiments with reference to the accompanying figures. Show it:

Fig. 8 is a perspective view of a frame provided for suspending the icemaker therefrom; and

9 is a partial view of a side part of the frame of Fig. 8.

Fig. 1 is a perspective view of a freezer with a body 1 and an open door 2, which enclose a divided into several compartments interior 3. Each compartment is closed by a flap 4 and 5, which is pivotable about a respective horizontal axis extending adjacent to its lower edge. The flaps 5 of the three lower compartments are closed and are each provided with a grip recess 6 extending over substantially the entire width of the flap. In the case of the flap 4 of the upper compartment, the recessed grip 6 is shortened, and in a lateral region of the flap, two recesses are formed, an upper, circular recess 7 and an angular recess 8 open towards the lower edge of the flap.

As can be seen in particular in the section of Fig. 2 and in the enlarged view of the flap 5 in Fig. 2, the lower, open-edged recess 8 is substantially filled by a handle 9, the (not visible in Fig. 2) Drawer of an arranged behind the flap 5 icemaker 10 belongs. Through the round recess 7 through a knob 1 1 of the ice maker 10 is accessible.

The icemaker 10 has a frame in the form of two closed-walled half-shells 12, which are hooked on its underside pivotally to each other, and of which one on its top elastic strap 13 carries, which are snapped onto locking projections 14 of the other half-shell. By bending up the bracket 13, the half-shells 12 can be unfolded to expose their interior for maintenance or cleaning.

On the upper sides of the half-shells 12 also hooks 24 are formed, the free ends of which face the rear end of the frame. As can be seen in the section of Fig. 3, the hooks 24 are provided to anchor the frame to two struts 25, which in later-described in more detail manner on side walls of the Body 1 are anchored. The free ends 26 of the hooks 24 are bent slightly downwards in the illustration of FIG. 3, in order to effect a latching on the struts 25 positively engaged around the hooks 24. Alternatively, for the same purpose, a bump may be formed on the upper edge of the half-shells 12 in each case opposite the free end of each hook.

In the open position of the flap 4, the entire ice maker 10 is accessible and can be removed by simply removing the struts 25. The removed ice maker can then be easily disassembled into its individual parts, for example, to clean them in a dishwasher. A re-assembly of the ice maker 10 is carried out accordingly by simply snapping onto the struts 25th

In order to fill the ice cube container 18, it is necessary to open the flap 4 and pull out the container 18 together with the frame carrying it from the shield 15, arms 16 and plate 17 to the front and push it back after filling. The housing consisting of the two half-shells 12 remains in place during this time.

As is apparent from Figs. 3 and 4, the knob 1 1 is rotatably mounted on a plate 15 which is pushed onto the upper front corner of the frame 12, 13 from the front. Attached to the plate 15 are two arms 16, shown in section in FIG. 5, which extend within the half-shells 12 over their entire depth, and at their end opposite the plate 15 carry a vertical plate 17. A Eisstückformbehälter 18 of a substantially semi-cylindrical shape, which is divided by parallel to the sectional plane of Fig. 5 extending partitions 19 into a plurality of ice pieces compartments 20, resting on concave inner surfaces of the arms 16 and is held longitudinally between the plate 15 and the plate 17 , Through an opening of the plate 15 of Eisstückformbehälter 18 is firmly connected to the knob 1 1. When the flap 4 is in the closed position, the shield 15 fits closely against the back of the flap 4, completely covering the edge of the recess 7. Accordingly, the front sides of the half-shells 12 are close to the back of the closed flap 4 and cover the recess 8. An air exchange between the closed by the flap 4 compartment and its surroundings is therefore only possible with the door 4 closed by air through the narrow spaces between the knob 1 1 and the surrounding edge of the recess 7 and flows between the rear of the flap 4 and the shield 15 and between the sides of the handle 9 and the edges of the recess 8 and between the back of the flap 4 and the front of the half-shells 12 along. A significant exchange of air and heat does not take place in this way.

If later the finished ice cubes are to be released from the container 18, it is no longer necessary to open the flap 4; it is sufficient to turn the knob 1 1 clockwise until the ice cube container 18 reaches the position shown in Fig. 5 as a dashed outline position in which it abuts with an edge to a protruding from the plate 17 rib 21.

By turning the knob 1 1 beyond this position, the Eisstückformbehälter 18 is elastically deformed, which solve the pieces of ice formed therein and fall between the two arms 16 into a connected to the handle 9 thrust blade 22 in the lower region of the frame. The thrust blade 22 is slightly smaller in cross-section than the open-edged recess 8, so that they can be pulled out by the latter. The release of the pieces of ice and their removal is done so without opening the door 4.

A modified embodiment of the ice cube maker is shown in Figs. 6 and 7. The shield 15 is omitted here; instead, the knob 1 1 extends directly through an opening at the front of the half-shells 12, and the ice-maker box 18 is sized so that it can be pulled out through this opening. Fig. 6 shows the Eisstückformbehälter 18 resting on two extending in the depth direction arms 16, which are stationary in the frame 12, 13. A half shell 12 carries a series of inwardly projecting hooks 23, one for each shape of the ice mold container 18. The hooks 23 differ slightly in their dimensions so that upon rotation of the ice mold container 18, one hook after another with a piece of ice in a mold the container 18 comes into contact and pushes it out of the mold. The loosened pieces of ice fall as in the embodiment of Figures 3 to 5 in a drawer 22 below the Eisstückformbehälters 18, which can be pulled out by means of the handle 9 without the flap 4 to open. Fig. 8 is a perspective view showing the already mentioned, parallel between the side walls of the body extending struts 25 and two mold parts 27 which connect the struts 25 with the side walls of the body 1, not shown in the figure.

The struts 25 are hollow profiles with rounded rectangular cross-section made of aluminum, stainless steel or a bending-resistant, in particular fiber-reinforced plastic. The molded parts 27 are injection-molded plastic parts having a front wall 28 and a rear wall each in the form of two triangles overlapping at their corners and the horizontal and vertical wall sections 29 to 32 connecting the catheters of the right-angled triangles. From the outer sides of the vertical wall sections 32 are pins 33 from which are provided to engage positively in not shown recesses of the side walls of the body 1. On the mutually facing inner sides of the vertical wall portions 30 support ribs 35 are arranged for the support of the struts 25, which are shown in Fig. 9 and described with reference to this figure. The horizontal wall portion 29 is divided by a notch 34.

9 shows a plan view of the insides of the vertical wall sections 30, 32 of a part of the molded parts 27. A hook-shaped support rib 35 extends downwardly from the horizontal wall section 29, terminating in a section 36 parallel to the wall section 29. The carrier rib 35 is connected in one piece with the vertical wall portion 30 along its entire length. A strut 25 is shown positively received between the support rib 35 and the wall portion 29.

The length of the strut 25 is dimensioned so that their longitudinal ends abut each of the vertical wall portions 30 of the two mold parts 27 or with little play, so that the strut 25 by moving in its longitudinal direction not from the support rib 35 of the two mold parts 27 solvable is.

A displacement of the strut 25 in the depth direction of the body is locked in one direction by the support rib 35 itself and in the opposite direction by a rib 37, of which a longitudinal end 38 of a narrow side of the strut 25 at a small distance opposite. The opposite longitudinal end fuses with a side wall of the notch 34. The rib 37 is integrally connected to the wall portion 30 only on a part of its length, in the perspective of FIG. 9, to the right of a dashed boundary line 39. The left of the line 39 lying part of the rib 37 thus forms a tongue 40, which, as shown in the figure 9 as a dashed outline, is flexibly deflected downwards. In order to stiffen the rib 37 in its remaining, integrally connected to the wall portion 30 region 41, this has a wavy course.

The horizontal wall portion 29 and the rib 37 together define a groove 42 that is wide enough to horizontally translate one end of the strut 25 therein. As shown in Fig. 8 using the example of the rear strut 25, the struts 25 can occupy a dashed oblique position, in which one end of the strut 25 is held by the carrier rib 25 of the mold parts 27, while the other end of the groove 42nd the opposite of the other molding 27, but without intervening in this. In this position, the strut is easily placed, when the mold parts 27 are inserted with their pins 33 in the corresponding recesses of the side walls. By turning the strut 25 about its held on the support rib 35 end in a vertical position to the side walls their other end gradually engages in the groove 42 engages and reaches in this one drawn in Fig. 9 as a dashed cross-section 25 a position in which they the tongue 40 touches and this opposes a further rotation of the strut 25. When the strut 25 is further rotated against the resistance of the tongue 40, it undergoes a position indicated at 25b in Fig. 9 in which the tongue 40 is resiliently displaced downwardly. The displaced tongue 40 is shown as a dashed outline. From the position 25b out the end of the strut 25 can finally engage between the support rib 25 and the wall 29, as shown in the figure as a solid outline, and the tongue 40 returns to its relaxed position shown in relaxed, in which it rotation of the Strut 25 blocked in the opposite direction and thereby fixed.

In order to solve the strut 25 again if necessary, it is sufficient to insert a finger into the groove 42 in order to press the tongue 40 down so far that it allows a rotation of the strut 25 again.
