Definitions

  • the present invention relates to a household appliance with a usable space which can be closed by means of a door pivotably mounted about a horizontal hinge axis, and a storage space in which the door can be moved by means of a guide system which has at least one guide element assigned to the door, which in one of the Household appliance associated slide track is guided.
  • DE 199 06 913 discloses a generic household appliance with a door that closes a usable space in the household appliance.
  • An opening with a guide system arranged therein is formed in a horizontal plane below the usable space. The door can be pushed into the opening via the guide system.
  • the object of the present invention is to provide a household appliance with a door which enables an ergonomically advantageous opening and closing movement of the door for an operator.
  • the door is assigned at least one weight compensation arrangement.
  • the weight balancing arrangement exerts a balancing force acting against the weight of the door on the door during a movement of the door. This ensures that the weight of the door is not absorbed by an operator during the door movement, but the operator is relieved of the weight of the door.
  • the weight compensation arrangement Since the weight of the door is balanced by the weight compensation arrangement, a driving force for opening and closing the door is advantageously reduced.
  • an inexpensive drive motor with lower power can therefore be used.
  • the drive force to be opened or closed by the operator to open or close the door is reduced, which results in an ergonomically more favorable actuation of the door.
  • the weight compensation arrangement is in engagement with the door only when the door is pivoted, while it is out of engagement with the door when the door is moved horizontally. When the door moves horizontally, the weight of the door is absorbed by the guide system. This ensures extremely smooth horizontal movement of the door.
  • the weight balancing arrangement can interact directly with the guide element of the door.
  • the movement of a guide element guided in a slide track can be influenced directly in order to exert the compensating force on the door.
  • a frictional force between the slide track and the guide element which can be displaced therein can be increased.
  • the increased frictional force acts as a balancing force on the door.
  • the weight compensation arrangement can have a spring which exerts a spring force on the door or the guide element as a compensation force.
  • the spring can advantageously cooperate with a pivot lever by means of which the spring force is exerted on the guide element. On the one hand, this enables a compensating torque to be exerted on the guide element over a correspondingly selected lever arm length of the swivel lever. On the other hand, due to a suitable swiveling radius of the swiveling lever, the swiveling lever can be in engagement with the guide element of the door only in certain path sections of the slide path. For example, in a horizontal path section of the slide path, it can be advantageous for smooth door movement if the pivot lever is out of engagement with the guide element.
  • the guide element runs during a pivoting movement of the door from its closed position in a special starting section of the slide track; the pivoting movement of the door takes place during a course of the guide element within this starting section.
  • Weight balancing arrangement in the area of the start section engages with the door.
  • the door is arranged vertically in a closed position and can be pivoted downwards or upwards into an open position, it may be advantageous that the door is initially out of engagement with the weight compensation arrangement at the beginning of the opening movement from the closed position. This simplifies an initial movement of the door from its closed position for the operator.
  • the weight compensation arrangement preferably engages with the door in the direction of the open position by a pivoting angle of 20 ° after the vertical closed position.
  • the pivot lever acts as a stop biased by the spring, which signals the operator a certain pivot position of the door. The operator can thereby move the door quickly and safely into this particular pivot position.
  • an additional holding element can be assigned to the slide track. To hold the door stably in this swivel position, the holding element presses the guide element of the door in the direction of the swivel lever.
  • the pivoting lever is out of engagement with the guide element.
  • the pivoting lever can be pressed against a first end stop by means of the spring.
  • the pivot lever In order to ensure that the pivot lever remains securely out of engagement with the guide element in the insertion section of the slide track during the course of the guide element, the pivot lever is pressed in this region by means of the spring against a second end stop. It is also advantageous if the swivel lever has a driver. When moving the door from the insertion section into the start section of the slide track, the driver engages with the guide element and can thereby automatically bring the swivel lever back into operative connection with the guide element.

  • FIG. 1 shows a cooking appliance 1 as a household appliance.
  • the cooking device 1 has operating and display elements 2 on the front with an assigned control unit.
  • a cooking space 3 is also provided in the cooking device 1.
  • the cooking space 3 is delimited by a muffle 4 which is open at the front.
  • the front opening of the muffle 4 is framed by a front muffle frame 8.
  • the cooking space 3 can be closed by means of a door 5, which is pivotably mounted about a horizontal hinge axis 12.
  • the door 5 has an inner door pane 7 and an outer door pane 9 made of glass or glass ceramic.
  • a door handle 17 is provided on an upper end face 6 of the door 5 and is pivotably mounted in a bearing housing 21.
  • FIG. 2 the arrangement consisting of the door handle 17 and the bearing housing 21 is shown enlarged in sections in a perspective view.
  • the door handle 17 has a handle strip 13, which is connected to a pivoting part 16 via bearing blocks 15.
  • the pivoting part 16 forms the upper end face 6 of the door 5 and has pivots 19 on both sides in the longitudinal direction. These are rotatably supported in the bearing housing 21.
  • Both the bearing housing 21 and the swivel part 16 are preferably made as an injection molded part from a thermosetting plastic.
  • Stiffening elements 23 are formed on both long sides of the bearing housing 21. These plunge into a door interior 41 and are detachably fastened, for example screwed, to the side edge strips 25 of the door 5.
  • FIG. 3 shows a sectional view along the line AA from FIG. 2, in which the door panes 7, 9 are indicated in dashed lines. Accordingly, it is Stiffening element 27 in contact with the outer door pane 9, while the inner door pane 7 lies on a contact surface 22 of the bearing housing 21 with the interposition of a seal 29. 3 further shows that the bearing housing 21 has a support surface 31. The support surface 31 is arranged between the lateral pivot pins 19 and extends in the axial direction of the swivel part 16 over almost the entire length of the swivel part 1.
  • the door handle 17 is assigned a tension spring 39 which biases the door handle 17 in a pivoting direction.
  • the tension spring 39 is provided below the bearing housing 21 and extends in the longitudinal direction of the bearing housing 21.
  • the tension spring 39 is freely suspended in the door interior 41 formed between the door panes 7, 9. The freely suspended arrangement of the tension spring 39 within the door interior 41 results in free expansion and thus a low-wear load on the tension spring 39.
  • the two ends of the tension spring 39 are each connected to the swivel part 16 via a first tension cable 43 in order to transmit a tension spring force to the swivel part 16.
  • the first traction cables 43 are guided to cam plates 47 via deflection rollers 45, which are rotatably mounted on the stiffening elements 27.
  • the cams 47 are connected on both sides in a rotationally fixed manner to the longitudinal ends of the swivel part 16.
  • Each of the first traction ropes 43 is fixed to an attachment point 46 on the circumference of the cam plate 47.
  • the tension spring 39 pretensions the door handle 17 against the first stop 35 and exerts a first torque M1 in a pivoting direction on the door handle 17 (FIG. 4).
  • the cams 47 are arranged within lateral recesses of the swivel part 16. The cutouts are covered on the end face by cover sections 18 of the swivel part 16.
  • a second traction cable 48 engages on the circumference of each of the cams 47.
  • the second traction cable 48 is guided opposite the first traction cable 43 around the cam plate 47 and fixed at the attachment point 46 on the circumference of the cam plate 47.
  • the first and second pull cables 43, 48 and the cam plates 47 form components of a control gear 38.
  • the control gear 38 transmits a pivoting movement of the door 5 to the door handle 17, ie when the door 5 is pivoted in a first pivoting direction, the control gear 38 pivots the door handle 17 in one direction first pivot direction opposite second pivot direction.
  • FIG. 4 shows an upper and lower section of the door 5 in a sectional illustration along the line B-B from FIG. 1.
  • the door 5 is arranged in a closed position.
  • a drive drum 54 is arranged, which serves as a drive part of the control gear.
  • a rotary movement is transmitted to the cam plate 47 via the pull cable 48.
  • the pull cable 48 engages on the circumference of the cam plate 47.
  • the traction cable 48 thus converts the rotary movement of the drive drum 54 into a rotary movement of the cam plate 47.
  • the drive drum 54 rotates.
  • the initiation of movement in the drive drum 54 is described later with reference to the second exemplary embodiment.
  • the rotary movement of the drive drum 54 is transmitted to the cam plate 47 via the pull cable 48, as a result of which a second torque M2 directed against the first torque M1 is exerted on the door handle 17. It can thereby be achieved that the horizontal orientation of the door handle 17 shown in FIG. 4 is maintained essentially independently of the pivoting position of the door 5.
  • a minimum value for the spring force of the tension spring 39 is used went out. This minimum value corresponds approximately to the frictional forces that have to be overcome to reset the door handle 17 after no actuation force F is exerted on the door handle 17.
  • the tension spring 39 is dimensioned such that the above-mentioned minimum value is approximately 10-20% of the spring force of the tension spring 39.
  • the spring force of the tension spring 39 is thus approximately five to ten times greater than this minimum value.
  • the comparatively large spring force allows the operator to have an ergonomically favorable operating feeling during a normal opening or closing operation of the door handle 17.
  • the radius of the cam plate 47 is of great importance.
  • the radius of the cam plate 47 determines the length of the lever arm and thus the size of the torque with which the pull cables 43, 48 engage the cam plate 47.
  • the gear ratio with which a drive movement of the control gear 38 is converted into a pivoting movement of the door handle 17 is determined by the cam disc radius.
  • the lever arm lengths r1, r2 of the cam plate 47 assigned to the first and second traction cables 43, 48 are of different sizes.
  • FIG. 5 illustrates an enlarged illustration of the cam plate 47 from FIG. 4.
  • the points of attack of the pull cables 43 and 48 are illustrated with the reference numerals A1 and A2.
  • the point of application A1 of the pull cable 43 moves counterclockwise during an opening process of the door 5 by a rotation angle section of approximately 90 ° along the circumference of the cam plate 47.
  • the lever arm length r1 is essentially constant.
  • the torque M1 exerted on the door handle 17 is therefore constant during the pivoting movement of the door 5.
  • the point of application A2 of the pull cable 48 moves by a rotation angle section of approximately 90 ° in a counterclockwise direction along the circumference of the cam disk 47.
  • the lever arm length r2 decreases when the door 5 swivels out of its closed position; that is, the torque M2 exerted on the door handle 17 is lowest in the horizontal door position.
  • Torque M2 opposes a weight of the door 5; the weight of the door 5 keeps the door 5 stable in its horizontal position.
  • the reduced torque M2 in the horizontal door position is therefore not able to compensate for the weight of the door.
  • the stable position of the door in its horizontal position is therefore not affected by the torque M2.
  • the transmission ratio of the control gear 38 can be changed depending on the pivoting position of the door 5.
  • Drive losses of the control gear 38 which occur, for example, at the start of a pivoting movement of the door due to an expansion of the pull cables 43, 48 or due to play in the control gear 38, can thus be compensated for.

  • the sliding piece 60 only comes into contact with the pivot lever 95 at a pivot angle of the door 5 of approximately 20 °. This simplifies the initial movement of the door for the operator 5 from their closed position.
  • the pivoted lever 95 preloaded according to FIG. 11 acts like a stop against which the slide 60 of the guide carriage 59 abuts when the door 5 opens. A certain pivoting position of the door 5 is thus signaled to the operator. In the present case, this pivot position corresponds to a removal position described later, in which a simple removal of the door 5 from the guide system 58 is made possible.
  • the weight compensation arrangement 94 has a pivotably mounted holding element 105 which is prestressed by means of a spring 106.
  • the spring-biased holding element 105 presses the slide 60 of the guide carriage 59 in the direction of the pivot lever 95 during the above-described initial movement of the door 5. As a result, the door 5 is held stably in the removal position shown in FIG.
  • the door 5 is mounted horizontally and shown pushed into the storage space 61.
  • the slider 60 of the guide carriage 59 of the door 5 is located in the horizontal insertion section 91 of the slide track 63.
  • the swivel lever 95 is out of engagement with the slide piece 60.
  • the swivel lever 95 therefore does not exert any compensating force on the door 5.
  • the swivel lever 95 is by means of the spring 103 clockwise against a second end stop 101, which is also formed by a rubber pad.
  • the pivot lever 95 has a driver 107.
  • the driver 107 of the swivel lever 95 projects into the slide track 63 in FIG. 12.
  • the slide piece 60 has been moved from the start section 90 into the insertion section 91 of the slide track 63.
  • the actuating lever 95 is biased against the second end stop 101 and is in a stationary position.
  • the slider 60 comes into engagement with the driver 107 of the swivel lever 95.
