Description

Dishwasher with a washing container that It can be removed as a case drawer.

The invention relates to a dishwasher with an essentially parallelepipedic straight or parallelepipedic shell oblique, open to the front side and with a washing container open at the top, whose side walls have edges upper, running parallel to the housing cover, the washing container can be removed as a drawer from the housing for loading and unloading and being inserted completely in the housing during washing operation, and during the washing operation at least one area of the wash container in contact with an area of the housing with the eventual interposition of a meeting. The invention relates to particular to a washing container, in which the walls sides have upper edges provided with joints, or a washing container, with which they are in contact during washing operation some side joints arranged in the Case.

A dishwasher of this type is known as example by WO 98/33426 A1. The advantages of a Drawer dishwashers of this type are described in detail in that document.

A difficulty in dishwasher drawers results from the need to seal the washing container open at the top to prevent liquid leakage from washed. For this, a tight contact must be established at liquids between the housing cover, or sealing strips that run parallel to it on the side walls of the housing, and the edges that define the opening of the container washed. As a rule, flexible joints are used at the edges and / or in the housing. To achieve the sealing effect, one of the Complementary sealing parts must exert a force against the other. In the anterior and posterior zone, this force is achieved through the insertion movement, which is done in perpendicular to the sealing surface. Instead, in the lateral edges the insertion movement runs parallel to the two sealing surfaces. They must be adopted therefore measures with which to generate a force that has a component perpendicular to the lateral sealing surfaces.

To do this, in a known embodiment by WO 98/33426 A1, the housing cover moves on the washing container at the end of the insertion operation. In order to effect such descent, an expensive mechanism of adjustment that deviates from force resulting from the insertion movement on the lid

An additional embodiment example of WO 98/33426 A1 uses a washing container, which in the front is higher than in the back, so that the edges of the side walls run inclined backward. In a cover that runs correspondingly inclined or a corresponding sealing strip is achieved then that the insertion movement no longer runs in parallel to the sealing edge and thus generate a force on the complementary sealing parts. Due to oblique development Several drawbacks occur from the edges. On the one hand decreases the height of the washing container, which reduces its capacity. On the other hand, the residual water stagnant over the sloping edges runs back towards the inside of the Case.

They are also known from WO 98/33426 A1 variants with flip tops or "endless" caps supported on rollers, which nevertheless have disadvantages in terms of their tightness Also the descent of joints inflating the joint itself or by an associated activation mechanism described in the WO 98/33426 A1.

The invention poses the problem of creating a structurally simple possibility and, nevertheless, of safe operation, to seal the washing container inside the housing.

According to the invention, this problem is solved. by dishwasher with the characteristics of the independent claims 1, 9 and 15. Configurations and advantageous improvements of the invention are obtained respectively from the following claims Dependents

The advantage that can be achieved through invention consists of the simple structure of the housing and the washing container, the shape being kept in particular straight parallelepipedic or given the oblique parallelepipedic case of wash bowl

In a first variant, this advantage is achieved because the washing container, at least in the area of the edges superior for almost the entire length, or with respect to their outer dimensions have a width that decreases from the front backwards or with respect to its interior dimensions it has a width that increases from front to back, and because either housing or a gasket arranged in the housing has at least one contact surface adapted to the contour development of the wash bowl

In a first embodiment of this variant, in which the washing vessel, at least in the area of the upper edges for almost the entire length, has a width decreasing, they are arranged on the upper edges of the washing container together that during washing operation they are in contact with an area of the housing also with a width which is reduced from front to back. In this way the container Washing can be manufactured together with the seals so very simple, for example in a two injection procedure components.

In an advantageous embodiment, in which the washing container, at least in the area of the edges superior for almost the entire length, with respect to its dimensions exteriors have a decreasing width, are arranged together in the inner edges formed by the side walls of the housing and the cover of the housing, and the width of the area between the joint contact surfaces also decreases from front to back. By arranging the boards in the housing, these are protected and a risk of damage by the Dishwasher user is reduced.

In addition, it is advantageous that the area that has a decreasing width is set inclined towards inside with respect to the rest of the side walls. In this way This zone can be easily configured as a bevel arranged on the outer side of the side wall edges with angle a constant, but with a depth that increases from front to back.

In an embodiment especially advantageous, in which the washing container, at least in the area of the upper edges for almost the entire length, with respect to their interior dimensions have a width that increases from the front backwards, some joints are arranged in the housing cover, that go inside the washing container, and that with with respect to its contact surfaces with sealing effect They are adapted to the contours of the washing container. Through the arrangement of the sealing surfaces on the side inside the washing container prevents liquid from reaching between the seal and the sealing surface, leave the container wash and get inside the housing.

Also in this embodiment is advantageous that the area having an increasing width is set inclined outward with respect to the rest of the side walls, since then it can be configured as bezel arranged on the inner side of the side wall edges with a constant angle, but with a depth that increases from front to back.

In an additional variant, which has a wash container in which the side walls have edges upper endowed with joints, a simple structure is achieved by means that in the insertion operation move the edge upper of the joint with respect to the upper edge of the container wash in the direction of the housing cover.

The media can be configured as guide slats arranged on the side walls of the housing, which run sloping downward from the back wall from the housing to the opening of the housing. Alternatively the means can be configured as rollers arranged about behind others on the side walls of the housing, whose axes they are placed on lines that run downwardly from the back wall of the housing to the opening of the Case. In a third variant the diameter of the rollers can increase towards the rear wall of the housing.

In this regard it is convenient that the inclination of the guide slats or the line ascends to approximately 1st.

It is also advantageous for the boards to understand slats or rollers with an area with a cross section in the form of c. This increases the elasticity of the joints, so the driving forces decrease.

Another variant, in which some side joints arranged in the housing are in contact with the container washing during washing operation, achieves its structure simple because the boards have L-shaped sections, whose horizontal sides in the state of use extend to below of horizontal edge protrusions in the state of use of the washing container, and because the edge projections run from way tilted down from the rear wall of the container wash to the previous wall.

A special advantage of this variant is obtained by arranging the gasket inside the housing, of This mode is protected against damage due to washing agent that falls or similar.

A simple structure of a dishwasher this type is also achieved because the edge protrusions are formed by side wall sections of the washing container in the form of wedge, directed outward towards the side walls of the housing with respect to the rest of the washing container. In this way the washing container can be manufactured as a molding part by injection, therefore a separate incorporation is dispensed with of the edge ledges.

In this regard it is convenient that the inclination of the guide slats or the line ascends to approximately 1st.

It is also advantageous that the joints exceed in height the upper edge of the wash container with a lip of tightness conformed. This avoids that during the washing operation liquid arrives above the edge of the wash container and then drip into the housing with the wash container removed. By interleaving a labyrinth of this type upstream of the sealing plane Main security is increased.

The dishwashers 1 represented in the figures 1 and 7 have in each case a washing container 2 essentially straight parallelepiped, which for loading and unloading can dramatically removed from a casing 2 also essentially straight parallelepipedic. For this, the housing 3 is configured as open way to the front side 4. The rear wall 5, the side walls 6, the cover 7 and the base not shown in the drawings, are preferably made of metal and so known are joined in the housing form described above. The sliding guide of the washing container 2 is performed by telescopic rails known in themselves, designated in the drawings with 18.

The washing container is manufactured preferably as a plastic injection molded part of a single piece and is open at the top. The latter has as a consequence that on the side walls 8 of the wall 9 posterior and the anterior wall 10 in each case an edge 8.1 is formed, 9.1 and 10.1 higher. In this respect the rear wall 9 has preferably the same height as the side walls 8, without however you can also have a height offset reduced. The previous wall 10 is preferably configured more high than the side walls 8 and exceeds in height the cover 7 of the housing, may be covered by a 3 1 decoration plate. The basic precondition for the configuration according to the invention of the dishwasher is just that the edges 8.1 of the 8 side walls run parallel to the plane of the cover 7 of the housing.

To avoid, during the operation of wash, in which the wash container 2 is inserted completely in the housing 3 as shown in figures 5 and 11, the washing liquid outlet of the container 2 into the housing, at least a tightness of these two must be made constructive elements among themselves. In this regard they can be used, between the rear wall 9 of the wash container and the wall 5 rear of the housing or cover 7 of the housing and between the wall Previous 10 of the washing container and the previous 7.1 edge of the housing cover 7, conventional sealing profiles, no represented in the drawings (in the housing and / or in the container washing), since at these points the necessary force for the sealing effect of a complementary sealing part over the other by insertion movement. Instead, in the lateral upper 8.1 edges the insertion movement runs in parallel to the two sealing surfaces. They must be adopted therefore measures with which to generate a force that has a component perpendicular to the sealing surfaces lateral.

Figures 1 to 6 show a first variant of a tightness of this type in the area of the walls lateral, figures 7 to 12 show a second variant. In both variants the upper edges 8.1 of the side walls 8 of the washing vessel are provided with bezels 12, which with a constant inclination angle α have a depth T which increases from the anterior wall 10 to the posterior wall 9, and that form the sealing surfaces, that is, the areas in contact with the joints 13.

In the first variant represented in the Figures 1 to 6, the bezels 12 are arranged on the side exterior of the side walls 8. Figure 2 shows the bezels 12 shaded. In it it can be seen that the edges 12.1 upper bevels 12, which also define the edge 8.1 upper side 8 walls of the wash container, they run inwards and, thus, the wash container in this area, with respect to its exterior dimensions, has a width which decreases from the anterior wall 10 towards the posterior wall 9. In figure 2 this is clarified by the indications B_ {V} and B_ {of width, and it can be seen that B_ {V} is smaller than B_ {H}. Instead, the lower edges 12.2 of the bezels 12 define an area in which the side walls 8 maintain a constant width B_ {A}.

In the interior edges formed by the side walls 6 of the housing and cover 7 of the housing are arranged together 13 (see Figures 4 and 6), which with respect to its contact surfaces 14 with sealing effect are adapted to the bezels 12. For this purpose the joints 13 have contact surfaces 14, which are arranged obliquely and in the that the cross section and therefore the width b of the own contact surfaces 14 increases from front to back. From in this way the width of the area between the left joint 13 and the right decreases from front to back. The configuration previously described of the sealing surfaces (bevels 12) and of the contact surfaces 14 makes the surfaces of tightness, with the washing container 2 removed (see Figure 3), are not yet in contact with surfaces 14 of Contact. Only in the last part of the insertion movement of the washing container 2 (see figure 5) the surfaces of tightness come into contact with contact surfaces 14. In this way the wear of the joints 13 is kept reduced, since that a friction between the pieces hardly takes place Complementary sealing. In addition, through the provision previously described, it is achieved that the force resulting from the insertion movement have a component directed at perpendicular to the contact or sealing surfaces 14 and therefore generate a sealing effect. Of the representations in section (see figures 4 and 6) can be deduced also that the seals 13 have in each case also a lip 15 of shaped seal that enters inside the container 2 washing and thus forms a front shield that protects the true seals 13 against too high a request with washing liquid

Figures 7 to 12 show a second variant, in which two joints 16 even go inside of the washing container. Figures 7 and 8 show that, in this case, the bezel 12 is arranged on the inner side of the walls 8 sides at the upper 8.1 edges. Thus the edges 12.1 bevel upper run out, that is, the washing container has in this area with respect to its dimensions interiors a width that increases from the anterior wall (width B_ {V}) towards the back wall (width B_ {H}). According to bevel configuration 12, at the seals 16 shown in the Figures 10 and 12 the contact surface 17 is directed towards outside. Otherwise the sealing effect in the course of insertion movement of the washing container 2 (figures 9 and 11) It is analogous to the first variant.

In both variants it is advantageous to inject the joints 13 or 16 and also the anterior and posterior joints not represented on cover 7. Then it may be convenient to manufacture the cover 7 from plastic or insert in the metal housing 3 an additional inner cover (not shown), so you can a two component injection procedure is used.

The dishwasher 101 has a container 102 of wash which, as shown in figure 13, can be removed as a drawer of the housing 103 for loading and unloading. For the container 102 is arranged in a housing 103 essentially straight parallelepiped or oblique parallelepiped, which It is set open to the front side 104 and has a wall 105 posterior on opposite side. The housing 103 is manufactured to Starting from metal or plastic. On its two side walls 106 is fixed in each case the outer guide of a telescopic rail 107 (see Figures 15 and 17).

The washing container 102 is also configured in a straight parallelepipedic or parallelepipedic manner oblique and is open at the top. This has as consequence that in each wall an upper edge 108 is formed. TO in this respect the rear wall 109 preferably has the same height than the side walls 110, however it can also present a displacement in reduced height. Wall 111 above is preferably set higher than the walls 110 sides and exceeds the height 112 of the housing, can be coated in a known manner by a decoration plate 113. The basic precondition for the configuration according to the invention of the dishwasher is just that the edges 108 of the walls 110 sides run parallel to the cover 112 of the housing. He container 102 is made of plastic, it can be manufactured by example as a single-piece plastic injection molded part piece. Recesses are arranged on the side walls 110 (no represented) to house the inner guides (not shown) of telescopic lanes 107. The union of the inner guides with the side walls 110 it can be performed in a known manner by screws, shaped pins or retention hooks and not It is represented in the drawings.

To avoid, during the operation of wash, in which the wash container 102 is inserted completely in the housing 103 as shown in Figure 14, the washing liquid outlet of the container inside the housing 103, the contact area of the upper edges 108 of the Side walls 110 in the cover 112 of the housing is sealed. For this, it is fixed on the two upper edges 108 in each case a seal 115 (see figures 16 and 18), for example by adhesion, screwed or similar. Board 115 has a first section 116, which is configured in the form of c, the zone 117 open in each case to the side wall 106 of the housing 103 and surrounding a guide strip 118. Instead of ribbon 118 guide can also be used several rollers arranged about behind others (not represented). It is important that the surface directed towards the upper side 120 of the c-shaped section 116, in the example of embodiment shown it is the upper side 119 of the guide strip 118, run tilted down from the back wall 105 of the housing to the opening of the housing in the front side 104. This can be achieved by fixing inclined with an angle α (see Figure 17a), by wedge-shaped guide slats (not shown), by rollers (not shown), whose axes are located on a line tilted, running the tilt down from the wall 105 rear of the housing towards the opening of the housing in the front side 104, or by rollers with a diameter that increases towards the rear wall 105 of the housing. Through one of these measures described above is achieved that the upper side 120 of the c-shaped section 116 is pressed up when inserting the wash container 102. In this way a lip 121 of tightness, which is formed on this side 120, enter contact with housing cover 112. Because this contact only takes place in the last part of the insertion movement, only reduced driving forces and wear of The boards is reduced.

The dishwasher 201 has a container 202 of wash which, as shown in figure 19, can be removed as a drawer of the housing 203 for loading and unloading. For the container 202 is arranged in a housing 203 essentially straight parallelepiped or oblique parallelepiped, which it is configured open towards the front side 204 and has in the opposite side a rear wall 205. The housing 203 is manufactured from metal or plastic. On its two side walls 206 is fixed in each case the outer guide 207 of a telescopic rail (see Figures 21 and 23).

The washing container 202 is also configured in a straight parallelepipedic or parallelepipedic manner oblique and is open at the top. This has as Consequently, an upper edge 208 is formed on each wall. TO in this respect the rear wall 209 preferably has the same height than the side walls 210, however it can also present a displacement in reduced height. The wall 211 above is preferably set higher than the walls 210 lateral and exceeds height 212 of the housing, can be coated in a known manner by a decoration plate 213. The basic precondition for the configuration according to the invention of the dishwasher is just that the edges 208 of the walls 210 sideways run parallel to the cover 212 of the housing. He container 202 is made of plastic, it can be manufactured by example as a single-piece plastic injection molded part piece. Recesses are arranged on the side walls 210 (no represented) to house the inner guides (not shown) of the 207 telescopic rails. The union of the inner guides with the side walls 210 it can be done in a known manner by screws, shaped pins or retention hooks and not It is represented in the drawings.

To avoid, during the operation of wash, in which the wash container 202 is inserted completely in the housing 203 as shown in figure 20, the washing liquid outlet of the container 202 inside the housing 203, are arranged in the corners 216 between the walls 206 sides of the housing and cover 212 of the housing in each case joints 215 (see figures 22 and 24). These have a L-shaped section 217, and a shaped sealing lip 218 in the same. The washing container 202 is widened in its side walls 210 in the upper area out, that is, towards the side walls 206 of the housing. These widenings 219 are wedge-shaped, as can be seen in the views laterals shown in figures 21 and 23, so that they form edge ledges 220, which run in an inclined manner down from the rear wall 209 of the wash container towards the previous wall 211. The angle α of inclination amounts to approximately 1 ° (see figure 23a). The sides 221 horizontal joints 215 are hooked below the rims 220 edge. When inserting the washing container 202, the tilt ensures that the edge projections 220 are pressed into the last part of the insertion movement against the seals 215 and consequently the sealing effect is achieved. The lips 218 of tight sealing exceed the edges 208 upper side walls 210 of the wash container, as can be seen in figure 20. Using tip 222 directed down the lips 218 of tightness a a labyrinth-like seal, which is interspersed upstream of the main sealing plane.
