Description

Technical field

This invention relates to a household appliance in the form of a cabinet with a housing surrounding the inner chamber, and with at least one crossbar that is mounted with its introduction into the first and second cutouts in the first and second opposite walls of the inner chamber, with at least the first of the cutouts is part of the groove made in the wall.

State of the art

Known devices of this kind are, for example, refrigerators with partitions in the form of a lattice, which is formed by two wire rails extending in the transverse direction with respect to the housing, and with longitudinally extending wire elements connecting these wire rails to each other, and the wire rails are included horizontal grooves in the side walls of the housing.

These crossbars or partitions to which they relate are generally pulled forward from the grooves without noticeable resistance, therefore, they are not suitable for securing the built-in assemblies on them, to which forces directed parallel to the grooves are applied in operation.

Disclosure of invention

Therefore, there is a need for a household appliance that provides reliable fastening of such embedded units.

The problem is solved in such a way that in a household appliance with a housing surrounding the inner chamber and having at least one crossbar, which is mounted with the introduction into the first and second cuts in the first and second opposite walls of the inner chamber, and at least the first of the cuts is part of the groove made in the wall, a flexible locking protrusion enters the groove, which blocks the movement of the first end of the crossbar outward from the notch along the groove and is forced out of the groove by moving the first end of this crossbar along the groove along rule to the neckline. Thus, the crossbar is easily mounted, but in the installed state it cannot be easily removed from its mounted position by a force directed to the side opposite to the mounting direction.

If each of the cutouts on both walls of the chamber is part of one of the mutually parallel grooves, then the crossbar is mounted by its parallel shift in the direction along the grooves.

According to a preferred embodiment, the crossbar is rotatable relative to the second cut-out as the center, and the protrusion is forced out of the groove by the rotational movement of the cross-bar, the center of which is the second cut.

In order to minimize the possibility of obstructing the rotation of the bar from the side of the other integrated nodes of the inner chamber, the groove is preferably oriented substantially horizontally.

The first notch is preferably located at the closed longitudinal end of the groove, so that one locking protrusion is sufficient for essentially immobile holding the first end of the crossbar in the notch.

The protrusion is performed in the form of a flexible tongue entering the groove with a free end facing the notch. If the groove is bounded by two essentially parallel ribs extending from the vertical plane of the wall, then in a suitable embodiment, the tongue is formed by a segment of one of the ribs not connected with the plane of the wall.

To impart rigidity, at least one rib has a wavy shape.

Cutouts and a groove are made on fittings mounted on the inner side of the housing walls.

To ensure the stability of the hanging of the integrated nodes, it is advisable to provide at least two crossbars. The cutouts for these two rungs are preferably made on the same shaped part.

By an integrated assembly is meant, in particular, a frame on which a container is supported with the possibility of its extension.

According to a preferred embodiment of the invention, the integrated unit is an ice maker.

In this case, the container is a container for forming pieces of ice or a reservoir for collecting pieces of ice.

If there is a reservoir for collecting it, it is advisable to install it under the tank to form pieces of ice.

In order to remove the finished pieces of ice from the container for their formation, the latter is preferably pivoted between the first position in which the forming recesses of the container for forming ice pieces are open from above and in which the water poured into the forming recesses freezes, and the second position in which the open parts of the forming recesses are located below.

If the frame is placed in the compartment of the chamber, which is closed by the door, it is advisable to have a cutout in the door through which the container extends when the door is closed. Thus, firstly, the use of the container is simplified and accelerated, since there is no need to open and close the door;

secondly, the compartment containing the frame remains protected by the door from heat and moisture.

To minimize the possibility of penetration of warm air through the cutout in the door, the ice maker frame is preferably provided with a front panel, which, when the door is closed, is located opposite the door and closes the cutout.

To simplify the use of the retractable container, the latter is preferably provided with a handle, which in the mounted position of the container extends beyond the front panel of the frame into the cutout.

The rotatable handle of the ice maker, which serves to rotate the container to form pieces of ice, is also conveniently accessible through the cutout in the door when the door is closed. Thus, it is possible to extract ready-made pieces of ice from the mold without opening the door.

This rotatable handle is preferably attached to one end of the container to form pieces of ice, and the freedom of rotation caused by it is limited by the profile interacting with the second, opposite in length, end of the container to form pieces of ice.

In order to get the finished pieces of ice from the container for forming pieces of ice, the latter is preferably made with the possibility of its elastic deformation under the action of the torque applied to the rotatable handle.

In order to simplify the filling of the container for forming ice pieces and its subsequent placement again in the ice maker, the container for forming ice pieces is preferably suspended to rotate in a frame that is pulled out of the frame together with the container for forming ice pieces.

The implementation of the invention

Figure 1 is an axonometric view of a freezer with a housing 1 and an open door 2, which form a chamber 3, divided into several compartments. Each compartment is closed by a door 4 or 5, each of which is rotatable around a horizontal axis passing near its lower edge. The doors 5 of the three lower compartments are closed, and each of them is equipped with a handle-groove 6, which extends essentially over the entire width of the door. In the door 4 of the upper compartment, the handle-groove 6 is shortened, and in the side of the door there are two cutouts, an upper round cutout 7 and a cutout 8 of a rectangular shape, open from the lower edge of the door.

As can be seen, in particular, in the context of figure 2 and in the enlarged image of the door 5 in figure 2, the lower cutout 8 open from the side of the edge is essentially filled with a handle 9, which refers to the drawer (not visible in figure 2) of the ice maker 10, located behind the door 5. Through the circular cutout 7 there is access to the rotatable handle 11 of the ice maker 10.

The ice generator 10 has a frame in the form of two cup-shaped halves 12 with closed walls, which are pivotally connected to each other on the lower side and of which one has elastic brackets 13 on its upper side that snap onto the protrusions 14 of the other cup-shaped half of the frame. By folding up the staples 13, the cup-shaped halves 12 of the frame are opened to allow access to the interior for maintenance or cleaning.

In addition, on the upper sides of the cup-shaped halves 12 of the frame are hooks 24, the free ends of which are directed to the rear end of the frame. As can be seen in section in figure 3, the hooks 24 are provided for fixing the frame on two rungs 25, mounted on the side walls of the housing 1 in a manner that is described in more detail below. The free ends 26 of the hooks 24 in the image of figure 3 are slightly bent down in order to fix on the crossbars 25 covered by hooks 24 with a geometric closure. Alternatively, for the same purpose, protrusions are formed on the upper edge of the cup-shaped half 12 of the frame opposite the free ends of each hook.

When the door 4 is open, the entire ice maker 10 is accessible and dismantled by simply removing it from the rails 25. After that, the dismantled ice maker can be easily disassembled into separate parts, for example, to wash them in a dishwasher. Re-installation of the ice generator 10 is carried out accordingly simply by fixing it on the crossbars 25.

To fill the container 18 for pieces of ice, it is necessary to open the door 4 and remove the container 18 forward together with its supporting frame from the shield 15, the brackets 16 and the plate 17, and insert it again after filling. The frame, consisting of two cup-shaped halves 12, all this time remains in place.

As can be clearly seen in figures 3 and 4, the rotatable handle 11 is rotatably mounted on the flap 15, which is worn in front on the upper front corner of the frame 12, 13. On the flap 15 are fixed two shown in figure 5 in section of the bracket 16, which are inside the cup-shaped half of the frame 12 through their entire length in depth and at the end opposite the flap 15, support a vertical plate 17. A container 18 for forming pieces of ice, having a substantially cylindrical shape, which is divided into several compartments 20 for a piece ice baffles 19, parallel to the plane of the cut of figure 5, lies on the concave inner surfaces of the brackets 16 and is held in the longitudinal direction between the flap 15 and the plate 17. The container 18 for forming pieces of ice is rigidly connected to the rotary handle 11 through the hole in the flap 15. When the door 4 is in the closed position, the flap 15 fits snugly to the rear side of the door 4, while it completely covers the edge of the cutout 7. The front sides of the cup-shaped halves 12 of the frame respectively fit snugly against the back side of the closed door 4 and close the cutout 8. Therefore, when the door 4 is closed, air exchange between the compartment closed by the door 4 and the external environment is possible only by passing air through narrow intermediate spaces between the rotary handle 11 and the surrounding edge of the cutout 7, and also between the back side of the door 4 and the shield 15 or between the side surfaces of the handle 9 and the edges of the cutout 8, as well as between the rear side of the door 4 and the front side of the cup-shaped halves 12 of the frame. In this way, no significant air exchange and heat exchange can occur.

When, after some time, it is required to get ready pieces of ice from the container 18, it is no longer necessary to open the door 4; it is enough to turn the rotary knob 11 clockwise until the position of the container 18, shown in dashed contour, is reached in which it abuts against the edge 21 protruding from the plate 17.

With a further rotation of the rotary handle 11 for this position, the container 18 for the formation of ice pieces is elastically deformed, due to which the pieces of ice formed in it are separated and fall between the two brackets 16 into the drawer 22 connected to the handle 9 in the lower part of the frame. The cross section of the drawer 22 is slightly smaller than the cutout 8 open from one edge, so that the drawer is pulled out through it. Thus, the separation of pieces of ice and their removal are made without opening the door 4.

A modified embodiment of the device for forming pieces of ice is shown in figures 6 and 7. In this case, the shield 15 is not used; instead, the rotary handle 11 passes directly through the hole in the front side of the cup-shaped halves 12 of the frame, and the dimensions of the container 18 for forming pieces of ice are such that it is taken out through this hole. The figure 6 shows a container 18 for forming pieces of ice lying on two depth-extending brackets 16 that are fixedly located on the frame 12, 13. The cup-shaped half 12 of the frame has a series of hooks protruding downward 23, one row for each shape of the container 18 for forming pieces ice. The hooks 23 slightly differ from each other in size, so that when turning the container 18 to form pieces of ice, the hooks successively, one after another, come into contact with the pieces of ice in the forms of the container 18 and push them out of the molds. The released pieces fall, as in the case of the embodiment in figures 3-5, into the drawer 22 under the capacity 18 to form pieces of ice, which is obtained using the handle 9 without the need to open the door 4.

Figure 8 is an axonometric image that shows the already mentioned rails 25 located parallel between the sides of the frame, as well as two shaped parts 27 that connect the rails 25 to the side walls of the housing 1 not shown in the drawing.

The crossbars 25 are hollow sections of rectangular cross-section with rounded corners of aluminum, stainless steel or bend-resistant, in particular fiber-reinforced plastic. Shaped parts 27 are molded plastic products with a front wall 28 and a rear wall, each of which has the form of two intersecting at the corners of the triangles, and with horizontal and vertical segments 29-32 of the walls connecting the legs of these right-angled triangles. Trunnions 33 extend from the outer sides of the vertical wall segments 32, which are provided to insert them with a geometric closure into the not shown recesses of the side walls of the housing 1. On the inner sides of the vertical wall sections 30 facing each other, there are support ribs 35 for fixing the crossbars 25, which are depicted in figure 9 and described in connection with this figure. The horizontal segment 29 of the wall is divided by a recess 34.

The figure 9 shows a top view on the inner sides of the vertical segments 30, 32 of the walls of the part of one of the shaped parts 27. The bearing rib 35 in the form of a hook extends from the horizontal wall segment 29 to an arcuate downward, while it passes into a segment 36 parallel to the wall segment 29. The supporting rib 35 throughout its entire length is integral with the vertical segment 30 of the wall. The crossbar 25 is shown fixed with a geometric circuit between the bearing rib 35 and the segment 29 of the wall.

The length of the crossbar 25 is such that each of its longitudinal ends is adjacent to the vertical segments 30 of the wall of the two shaped parts 27 or is located opposite them with a small gap so that the crossbar 25 cannot be separated from the supporting ribs 35 of the two shaped parts 27 by shifting it in the longitudinal direction.

The advancement of the crossbar 25 along the depth of the casing is blocked in one direction by the carrier rib 35 itself, and in the opposite direction by the rib 37, opposite the longitudinal end 38 of which the narrow side of the crossbar 25 is located at an insignificant distance. The opposite longitudinal end merges with the side wall of the recess 34. The rib 37 only on the part of its length - in the image in figure 9 to the right of the dashed boundary line 39 - is inextricably connected with a segment 30 of the wall. The detail of the rib 37, located to the left of the line 39, forms a tongue 40, which has the ability to flexibly deviate downward, as shown in figure 9 by a dashed line. In order to impart rigidity to the rib 37 in the rest of its part 41, which is integral with the wall segment 30, it has a wave-like shape.

The horizontal wall segment 29 and the rib 37 together define a groove 42 that is wide enough to horizontally move the end of the crossbar 25 in it. As shown in FIG. 8 as an example of the rear crossbar 25, the crossbars 25 can occupy the deflected position shown in dotted form, in which one end of the corresponding the crossbar 25 is held by the bearing rib 35 of one of the molded parts 27, while the other end is opposite the groove 42 of the other molded part 27, but is not included in it. The crossbar is easily brought into this position when the shaped parts 27 enter their pins 33 into the corresponding recesses of the side walls. When the bar 25 is rotated around its end, held on the supporting rib 35, in a position perpendicular to the side walls, its other end gradually enters the groove 42 and reaches there the position shown in figure 9 as a dashed section 25a in which it touches the tongue 40 and this tongue prevents further rotation of the crossbar 25. If the crossbar 25, overcoming the resistance of the tongue 40, rotates further, it passes the position indicated in figure 9 by 25b, in which the protrusion 40 is elastically pushed down. The offset protrusion 40 is shown by a dashed line. From position 25b, the end of the crossbar ultimately extends to the position between the supporting rib 35 and the wall 29, as shown in the figure by a solid line, and the tongue 40 returns to the unstressed position shown by the solid line in which it blocks the rotation of the crossbar 25 in the opposite direction and thus fixes it.

To remove the crossbar 25 again, if necessary, it is enough to place a finger in the groove 42, pressing the tongue 40 down so that it again allows the crossbar 25 to be turned.
