In order to ensure that the domestic appliance is mounted in a reliable yet simple manner, the wall mounting device (23) is provided with a carrier element (31) which acts as a support for the domestic appliance.

Description

Household appliance, in particular high-level built-in cooking appliance with a

Wall mounting device

The present invention relates to a household appliance, in particular a built-in cooking appliance with a wall mounting device for mounting the household appliance on an essentially vertical kitchen wall.

A built-in cooking appliance is known from WO 98/04871. The high-level built-in cooking appliance has a cooking space that is surrounded by side walls, a front, rear and top wall. The built-in oven is attached to a vertical wall. The bottom-side cooking chamber opening can be closed with a lowerable bottom door.

The object of the present invention is to provide a reliable and simple installation of the household appliance on a vertical wall.

The object of the invention is achieved by a household appliance with the features of patent claim 1. Accordingly, the wall mounting device for stable mounting of the household appliance on the wall has a carrier element which carries the household appliance.

It is advantageous if the support element of the wall mounting device is arranged so as to be protected from view within a housing of the household appliance. This saves an additional installation space for the support element outside the housing of the household appliance.

In an advantageous embodiment, the support element of the wall mounting device can be formed by a number of frame strips. These extend along a rear wall of the housing. In order to ensure reliable support of the household appliance on the frame strips, the frame strips can extend over essentially the entire height of the rear wall of the housing. The support element is particularly torsionally rigid when it is manufactured as a support frame that is closed on the circumference. Such a torsionally rigid support frame is particularly advantageous in the case of an uneven vertical kitchen wall. The support frame is preferably made in one piece from a die casting. Die casting is advantageous in terms of weight savings and tool costs.

Another measure for a torsionally rigid support element can consist in designing the frame strips of the support element in a U-shaped or meandering cross-section.

Because of the high weight of a household appliance equipped with food to be cooked, reliable support of the household appliance is important. A particularly good support of the household appliance is obtained if the frame strips of the support frame run along the peripheral edges of the rear wall of the household appliance housing.

To absorb high bending forces, the carrier element can have at least one pair of side frame strips on each side of the household appliance. In this case, the housing of the household appliance can be mounted on the two outer frame strips. Further components provided within the housing, such as a muffle or a blower, can be mounted on the two inner frame strips.

Components provided within the housing can also be mounted on additional support brackets of the support element. Such additional support brackets can be held on the support element and extend away from the vertical kitchen wall.

Adjusting the household appliance in a building depth direction or adjusting the position of the household appliance in the building depth direction is particularly important if the household appliance is to be aligned in a row with other devices held on the vertical kitchen wall. For this purpose, the support element can preferably be mounted such that it can be tilted via a tilt axis and the wall mounting device can have an adjustment element for setting a tilt angle of the support element. The adjusting element can be designed as a pivot lever. The pivot lever can be pivotally mounted on a pivot axis and can engage on the support element for the household appliance in a lever arm length spaced apart from the pivot axis. As a result, the tilt angle of the carrier element or of the household appliance can be set as a function of the pivoting position of the pivoting lever. By suitable adjustment of the lever arm length on the swivel lever, the tilt angle of the household appliance can be set in a simple manner for an operator.

It is preferred if a tilting moment in the direction of the tilted second end position is exerted on the carrier element due to the dead weight of the household appliance. As a result, the carrier element can always be pressed against the tilting moment in contact with the pivot lever. The adjustment movement of the pivot lever on the carrier element is thus always exerted against the tilting moment.

According to an advantageous embodiment of the invention, the pivoting lever can engage the tiltable carrier element in a first point of application in order to carry out the adjusting movement on the carrier element. In a second point of attack, the swivel lever can record an operating movement of an operator. The tilt angle of the household appliance can be adjusted in a simple manner for an operator by suitable adaptation of the lever arm length ratio assigned to the points of attack.

The operating force required by the operator for the swivel lever should be kept as low as possible. It is therefore advantageous if the lever arm length assigned to the first point of application is smaller than the lever arm length assigned to the second point of application. As a result, a sufficiently large actuating torque can be exerted on the swivel lever despite the low actuating force of the operator. It is particularly advantageous if the second lever arm length is at least twice as long as the first lever arm length.

The pivot lever can advantageously be mounted on one side on the pivot axis. The first and second points of application are thus on the same swivel side of the swivel lever. The swivel lever is therefore arranged in a simple and space-saving manner in the wall mounting device. It is advantageous if an additional movement transmission means acts on the swivel lever, in particular on the second point of application of the swivel lever. The movement transmission means converts an operating movement of an operator into the swiveling movement of the swiveling lever. The operating movement of the operator can thus be exerted on the pivoting lever regardless of the position of the pivoting lever.

In an advantageously simple embodiment, the movement transmission means can be formed as a rigid transmission lever. This takes up the operating movement of the operator at its first lever end. An opposite second lever end transmits the actuation movement to the swivel lever.

A linear stroke movement that is essentially parallel to the vertical wall, preferably a vertical stroke movement, is ergonomically particularly favorable for the operator. This vertical stroke movement can advantageously be absorbed by an adjusting screw that can be adjusted by the operator from the first lever end of the transmission lever.

The pivot lever and / or the transmission means for the pivot lever can advantageously be arranged within a housing of the household appliance. It is therefore not necessary to provide an additional installation space for the pivot lever and / or for the transmission means between a rear wall of the housing and the vertical wall. The housing can preferably have at least one access opening. Through this, the operator exerts an actuating movement on the pivot lever and / or the transmission means of the pivot lever from outside the housing.

It is particularly advantageous if the wall mounting device has a mounting element which is fixedly attached to the wall and which provides the tilting axis for the carrier element. The mounting element is thus interposed between the support element and the vertical wall. The support element can therefore be tilted against the mounting element on the wall regardless of the circumstances. In addition, the wall mounting device of the household appliance can have a vertical adjusting element which exerts a vertical stroke on its carrier element in order to adjust the height of the household appliance. Thus, outer furniture edges of the household appliance can be set not only in the depth direction, but also in a vertical direction.

For the height adjustment, it is particularly advantageous if the carrier element is vertically adjusted relative to the mounting element which is fixedly attached to the vertical wall. As a result, the vertical adjustment element is supported between the mounting element and the carrier element, for example without being supported on the kitchen floor.

For a compact design of the household appliance, it is advantageous if the vertical adjustment device is arranged inside the housing and is accessible from outside via an access opening in the housing.

It is ergonomically particularly favorable for the operator if the access opening for the pivoting lever and / or for its transmission means and the access opening for the vertical adjustment element are arranged spatially next to one another in the housing, for example on a floor-side housing wall facing the kitchen floor.

The invention is described below with reference to the attached figures. Show it:

Fig. 8 is a view corresponding to Figure 7, in which the carrier element is shown in a second tilted end position II.

1 shows a built-in cooking appliance with a housing 1. A rear wall 2 of the housing 1 is mounted on a vertical kitchen wall 3 in the manner of a wall cabinet. A cooking chamber 5 is defined in the housing 1 and can be checked via a viewing window 7 introduced into the housing 1 at the front. The cooking space 5 is delimited by a muffle 9. This is surrounded by a heat-insulating jacket, not shown. According to FIG. 2, the muffle 9 has a muffle opening 11 on the bottom. The muffle opening 11 can be closed by a bottom door 13 shown in FIG. 1. The bottom door 13 is held on a lifting rod 15 shown in FIG. 1, which can be actuated by an electric motor 16 arranged in the housing 1. In Figure 1, the bottom door 13 is shown lowered. The underside of the floor door 13 lies on a worktop 17 of a kitchen device.

For reasons of clarity, the underside of the built-in built-in cooking appliance is shown in FIG. 2 without the base door 13 and without the associated lifting rod 15. It can be seen from this that the muffle opening 11 is framed by a muffle frame 19 with a bottom end face. In addition to lead-through openings 20 for the lifting rod 15, two access openings 21 are formed in the bottom end face of the muffle frame 19. The access openings 21 allow an operator to operate adjusting screws 25, 27 of a wall mounting device 23 arranged in the housing 1 by means of a screwdriver. By means of the wall mounting device 23, the housing 1 can be shown in FIG Construction depth direction B and in a vertical direction V relative to adjacent wall cabinets.

The wall mounting device 23 is shown in FIG. 3 with the housing 1 omitted. Therefore, the adjusting screws 25, 27 arranged in pairs on both sides of the wall mounting device 23 can be seen. By actuating the first adjusting screws 25, a carrier element 31 carrying the housing 1 is adjusted in the depth B direction. By actuating the second adjusting screws 27, the carrier element 31 is adjusted in the vertical direction V.

Details of the wall mounting device 23 are described below. The wall mounting device 23 has, according to FIG. 5, on the one hand two stationary suspension rails 29. These are held vertically next to each other in the longitudinal direction on the kitchen wall 3. On the other hand, the wall mounting device 23 has the carrier element 31. According to FIG. 3, the carrier element 31 is mounted such that it can be tilted in the structural depth direction B via a tilt axis K on the suspension rails 29, as will be described later.

FIG. 4 shows the carrier element 31 without the suspension rails 29. The carrier element 31 is designed as a support frame. Each side of the support frame has a pair of vertically arranged side frame parts 33. These are manufactured as U-shaped sheet metal parts. The two pairs of side frame parts 33 are welded to an upper and a lower cross frame part 35. The cross frame parts 35 are formed as meandering sheet metal profile parts in cross section. In FIG. 4, holder sections 37 are formed on the two inner side frame parts 33 for hanging support brackets 39 shown in FIG. The support brackets 39 carry the housing 1 of the built-in cooking appliance together with the muffle 9, the electric motor 16 for the lifting rod 15 and other functional parts of the cooking appliance.

As shown in FIG. 4, T-shaped recesses 41 are formed in the upper and lower transverse frame parts 35 between each pair of side frame parts 33. According to the T-shaped recesses 41 of the support frame 31, the U-shaped suspension rails 29 with side flanges 42 are formed according to FIG. According to FIG. 5, these protrude through the T-shaped recesses 41 of the support frame 31. The suspension rails 29 and the support frame 31 are arranged within the housing 1 indicated by dashed lines in FIG. As a result, the suspension rails 29 extend through housing openings in the rear wall 2 of the built-in cooking appliance to the outside. The suspension rails 29 also have undercuts 43. By means of this, the suspension rails 29 according to FIG. 7 are hung on a wall ledge 45 of the vertical wall 3. Lateral support ribs 47 are each formed at the lower end of the suspension rails 29. According to FIG. 5, a lower flank 49 of the lower transverse frame part 35 of the supporting frame 31 is seated on the supporting ribs 47 of the suspension rails 29. This can also be seen from FIG. 7: The meandering lower transverse frame part 35 of the supporting frame 31 can be seen in cross section. It can be seen that the lower side flank 49 of the transverse frame part 35 is seated on the supporting rib 47. 7 further shows that the side flange 42 of the suspension rail 29 has a horizontal play a in the T-shaped recesses

41 of the upper and lower transverse frame parts 35 is held. Opposing edges 55, 57 of the T-shaped recesses 41 of the support frame 31 thus form a first and a second end stop. The support frame 31 is therefore adjustable between its two end stops 55, 57 in the depth B direction of the built-in cooking appliance. Accordingly, the support frame 31 is shown in FIG. 7 in a first vertical end position I and in FIG. 8 in a second tilted end position II.

According to FIG. 7, the wall mounting device 23 has a holder 61 in the lower region of each of the suspension rails 29. The holder 61, which is produced as a sheet metal part, is formed with upper bent clamp sections 63. These engage behind the side flanges 42 of the suspension rails 29. The clip sections 63 of the holder 61 thus hold the lower left end stop 57 of the support frame 35 on the side flange

42 of the fixed suspension rail 29. The support frame 31 can therefore only be adjusted in the upper T-shaped recess 41 via the play a relative to the suspension rails 29. In contrast, a horizontal tilt axis K is formed between the lower side flank 49 of the support frame 31 and the support ribs 47 of the suspension rails 29. The support frame 31 can tilt in the depth B direction about the tilt axis K. The support frame 31 can therefore be tilted about the tilt axis K with respect to the stationary suspension rails 29 by means of a tilt angle between the upper first end stop 55 and the upper second end stop 57. Due to the weight of the Household appliances always have a tilting moment M on the support frame 31 in the direction of the arrow shown in FIG. 7.

FIG. 7 shows that a rod-like pull lever 67 is guided in a height-adjustable manner in the lower holder 61. For this purpose, a lower end 69 of the tension lever 67 engages with a lifting plate 71 guided vertically in the holder 61. A height position of the lifting plate 71 can be varied by the operator using the first adjusting screw 25 mounted in the bottom of the holder 61. 7 shows the lifting plate 71 in a first, lowest height position. An upper end 73 of the pull lever 67 is designed as a U-shaped hook which is in engagement with a pivot lever 75. As will be described later, the tilting angle of the support frame 31 relative to the fixed suspension rails 29 is set by means of the pivot lever 75. According to FIG. 6, the swivel lever 75 is a plate-shaped sheet metal part in which a through opening 77 is formed. The U-shaped hook 73 of the pull lever 67 is suspended in the through opening 77. Opposite, the pivot lever 75 has a T-shaped recess with two cone-like holding lugs 79 facing each other. It can be seen from FIG. 7 that the retaining lugs 79 of the pivoting lever 75 are arranged between an upper and lower meandering section of the upper transverse frame part 35. At the same time, the retaining lugs 79 of the swivel lever 75 engage behind the side flanges 42 of the suspension rails 29. The swivel lever 75 is thus pivotably mounted on the side flanges 42 of the suspension rails 29 on a pivot axis S.

In FIG. 7, the pivot lever 75 is in contact with a contact edge 82 of the transverse frame part 35 of the support frame 31 in a first point of application 81. The first point of engagement 81 is spaced from the pivot axis S over a first lever arm length li. A second point of engagement 83 is formed between the U-shaped hook 73 of the pull lever 67 and the passage opening 67 of the pivot lever 67. The second point of engagement 83 is spaced from the pivot axis S by a second lever arm length l ₂ , which is approximately twice as long as the first lever arm length. Due to the tilting moment M _k acting on the support frame 31, the contact edge 82 of the support frame 31 always presses the pivot lever 75 in a clockwise direction. Thus, the pivot lever 75 always exerts an upward pulling force on the pull lever 67. A reliable engagement between the pull lever 67 and the pivot lever 75 is therefore ensured. An adjustment process for adjusting the tilt angle of the support frame 31 in relation to the fixed suspension rails 29 is described below with reference to FIGS. 7 and 8. In FIG. 7, the support frame 31 is in the first vertical end position I. This means that the pivot lever 75 presses the upper left end stops 57 of the support frame 31 against the side flanges 42 of the fixed suspension rails 29 via the contact edge 82 of the support frame 31. To tilt the support frame 31 in the depth B direction, the operator adjusts the adjusting screw 25 such that the lifting plate 71 in the holder 61 moves upward from the lowest height position shown. The linear lifting movement of the lifting plate 71 upwards is transmitted to the pivot lever 75 via the pull lever 67. The pivot lever 75 therefore pivots clockwise upward. As a result, the contact edge 82 of the support frame 31 moves to the left along the pivot lever 75 in FIG. 7. The support frame 31 therefore tilts forward by a certain tilt angle in the structural depth direction B. 8 shows the support frame 31 in its second, maximally tilted end position II. In the second end position II, the lifting plate 71 has been adjusted vertically by means of the adjusting screw 25 from the first height position h-ι from FIG. 7 to the second height position h ₂ . Accordingly, the right end stops 55 of the support frame 31 are pressed in FIG. 8 by the tilting moment M _k into contact with the side flanges 42 of the fixed suspension rails 29.

In addition, the wall mounting device 23 according to the invention has the second adjustment screws 27 already mentioned. A vertical height adjustment of the support frame 31 of the household appliance can be accomplished with these. For this purpose, according to FIG. 3, the lower end of the suspension rails 29 is closed with a base plate 89. The second adjusting screw 27 is held in the base plate 89.

As shown in FIG. 8, the adjusting screw 27 shown in dashed lines is brought into contact with the lower side flank 49 of the lower cross frame profile part 35 of the support frame 31. The supporting frame 31 seated on the supporting ribs 47 is raised by the adjusting screw 27 by turning the adjusting screw 27 accordingly. As a result, the support frame 31 is adjusted vertically relative to the fixed suspension rails 29. In Figures 7 and 8, the support frame 29 is shown in its lowest height position. In this height position, as described above, the lower side flank 49 of the support frame 31 lies on the support ribs 47. The support frame 31 is adjusted vertically upwards by a corresponding rotation of the second adjusting screw 27. The lower side flank 49 of the support frame 31 detaches from the support ribs 47 of the suspension rails 29. In this case, the tilt axis K of the support frame 31 is no longer between the lower side flank 49 and the support rib 47, but between the adjusting screw 27 and the lower side flank 49 of the support frame 47.
