Definitions

  • the invention relates to a switching and/or adjusting panel for an appliance, especially for a domestic appliance, for switching and/or adjusting of an operation parameter of the appliance, wherein the panel has a panel cover element which extends in a transverse direction and wherein the panel has at least one functional element.
  • Switching or adjusting panels of this kind are well known in the art, especially for domestic ovens.
  • the assembly process for such panels is quite laborious and thus expensive. Often, parts of the panel are glued together during assembly. By this, a firm connection can be obtained.
  • the disadvantage of this process is that it is complicated to substitute a broken part of the panel construction. Also, to ensure a stable connection the parts to be glued must be prepared properly, i. e. they must be degreased.
  • the solution of this object according to the invention is characterized in that the panel cover element has a hook element in a top region (or alternatively in a bottom region) forming an undercut in a direction perpendicular to a front surface of the panel cover element and that the panel cover element has a plurality of snap elements in a bottom region (or alternatively in a top region) forming an undercut in a direction perpendicular to the front surface of the panel cover element, wherein the at least one functional element has a first section extending in the direction perpendicular to the front surface of the panel cover element when being in the mounted state, which abut against the undercut of the hook element and wherein the at least one functional element has a second section extending in the direction perpendicular to the front surface of the panel cover element when being in the mounted state, which abut against the undercut of the snap elements.
  • the panel has preferably at least two functional elements, wherein the at least two functional elements are preferably arranged side by side along the transverse direction of the panel cover element.
  • the hook element extends preferably along the entire width (in transverse direction, specifically in a horizontal direction) of the panel cover element and holds all of the functional elements in their position.
  • the panel cover element consists preferably of sheet metal.
  • the hook element can be formed by a bended portion of the panel cover element.
  • the snap elements can be formed from the material of the panel cover element; a preferred solution suggests that the snap elements are produced by a punching or by a plastic deformation process of the panel cover element.
  • At least one of the functional elements can be a carrier frame which can carry a component.
  • the component can be e. g. a switch.
  • the component can be a lamp.
  • At least one of the functional elements can be a housing element for an adjusting knob.
  • the panel cover element can have at least one opening for the passage of a switching or adjusting element.
  • the panel cover element can also have at least one opening for showing a display element.
  • a transparent element can be located between the panel cover element and the display element; the transparent element is preferably a glass panel or pane.
  • a specific beneficial function is thus a good guidance of the adjusting elements and adjustment knobs of the panel.
  • the different components can easily be mounted and dismounted what is of specific advantage in the case of substitution of broken parts during service work.
  • E. g. a clock can be dismounted without dismounting of the carrier frame element for the clock.
  • the design and the appearance respectively are not influenced by any unnecessary openings at the front surface of the panel cover element.
  • the functional element is designed as a guidance for an adjusting element or switch.
  • the functional element is basically a plate having a respective opening for penetration by the adjusting element or switch.
  • a functional element with a plane front surface can also be employed as a protection element.
  • a further advantage is that any necessary push button can be inserted after the functional element is mounted, i. e. snapped in. Then, the timer can be snapped in. This is not possible in the case of holders which are mounted on the timer from the rear side. This is an advantage for assembly and servicing of the appliance.
  • the proposed concept allows that no flaps or embossments must be machined from the visible front section of the panel cover element. This allows a higher degree of freedom in designing the appliance. No covering by other elements is necessary.
  • FIG 1 a cross sectional view can be seen of a switching and/or adjusting panel 1 which is part of a domestic oven.
  • the panel 1 has a panel cover element 2 made from sheet metal.
  • the sheet metal of the panel cover element 2 is bended to form a hook element 6, i. e. a part extending substantially in a direction N perpendicular to a front surface 9 of the panel cover element 2.
  • a hook section is formed extending a certain amount to the bottom to form an undercut 8 seen in direction N.
  • the panel cover element 2 has a section in the bottom region 11 which extends substantially in the direction N perpendicular to the front surface 9.
  • snap element 10 are formed which form an undercut 12 seen in direction N.
  • the whole panel cover element 2 extends horizontally and in a transverse direction T which is perpendicular on the drawing plane in FIG 1 .
  • the panel cover element 2 is designed to allow functional elements 3, 4, 5 (see FIG 1, 2 , and 3 ) to be firmly engaged with the panel cover element 2 by means of a snap connection / clip connection.
  • the functional element 3 in FIG 1 is a standard carrier frame which is connected to the panel cover element 2 in the following way:
  • the functional element 3 has a first section 13 in an upper area and a second section 14 in a bottom area. Both sections 12, 13 extend substantially in the direction N perpendicular to the front surface 9 (when being arranged in the mounted position).
  • the first section 13 is hanged under the hook element 6 in the top region 7 of the panel cover element 2.
  • the end of the first section 13 abuts against the undercut 8 of the hook element 6.
  • the functional element 3 is pivoted in the position shown in FIG 1 .
  • the second section 14 slides along the inner side of the section with the snap element 10 in the bottom region 11 of the panel cover element 2 until the end of the second section 14 snaps behind the undercut 12.
  • the functional element 3 is snap-fitted to the panel cover element 2.
  • the panel cover element 2 has openings at the front surface 9 as can be seen in FIG 8 . Openings 18 of circular shape are machined (punched) in the panel cover element 2 for switches which are mounted in the functional elements 3, 4, 5. Also an opening 20 is machined into the panel cover element 2 for a display element 21 (see FIG 2 ). By mounting the functional elements 3, 4, 5 in the described way the respective elements are brought into position to reach through the openings. As can be seen in FIG 1 , an adjusting element 19 is mounted in the functional element 3 which comes into the right alignment when the functional element 3 is mounted in the panel cover element 2.
  • the mounting of the other functional elements 4, 5 takes place in the same way as the assembly of the functional element 3 and the panel cover element 2.
  • the functional element 4 is a carrier frame for a component 15 which is a circuit board in the embodiment according FIG 2 .
  • the display element 21 is part of the functional element 4 according to FIG 2 .
  • a transparent element (glass pane) 22 is inserted in a respective opening near the surface 9 of the panel cover element 2.
  • the functional element 5 is a knob for adjusting of a parameter of the domestic appliance.
  • a controlling element 23 is part of the functional element 5. The adjustment is carried out by actuating (turning and/or pressing) an adjusting knob 16 which is connected with the controlling element 23.
  • a respective opening 17 is machined in the panel cover element 2.
  • the adjusting elements 19 which are pushbuttons
  • the functional element 3 can be e. g. a clock. It is also possible to mount the functional element 3 at first and than the other components. This is advantageous for changing elements.
  • adjustment elements 19 are inserted or snapped in at first in the functional element 4 before the component 15 (circuit board) is also connected by means of a snap-fit connection. Then, the functional element 4 is mounted on the panel cover element 2.
  • the panel cover element 2 can be seen in its extension in transverse direction T and with different openings 17, 18, 20 for adjusting elements and knobs as well as for a display element.
  • the hook element 6 can be seen under which the respective first sections 13 of the functional elements 3, 4, 5 are brought.
  • the plurality of snap elements 10 can be seen for fixing the different functional elements 3, 4, 5 with the panel cover element 2.
  • FIG 5 In FIG 5 , FIG 6 and FIG 7 functional elements 3, 4 and 5 are shown.
  • the controlling element 23 is fixed to the functional element 5 and to the adjusting knob 16 (fixed by means of screws or by a snap-fit connection). Then, the whole functional element 5 is mounted to the panel cover element 2 in the described way.
  • Additional parts like lamps can be mounted preferably also by a snap-fit connection to the functional elements 3, 4, 5.
  • a component 15 being a lamp is shown which is connected to the functional part in the mentioned way.
  • mount the functional element 3 at first.
  • the functional element 4 with the circuit board can be made from transparent material especially in the region of the opening 20 so that no glass pane is necessary.
  • the adjusting knob 16 and the adjusting element 19 are fed through the respective openings in the panel cover element 2 and are thus protected by the panel cover element 2.
  • the travel of the adjusting elements is always equal, i. e. no tolerances are added. No screws or additional parts are necessary for the fixation of the elements with the functional elements.
  • the panel needs not to be degreased in difference to the preknown process of gluing.
  • the snap-fit connection which is used widely for connecting the respective parts and elements is becomes very easy to substitute elements when carrying out service work.
  • the arrangement of the hook element and the snap elements can also be the other way around, i. e. the hook element can be arranged in the bottom region and the snap elements can be arranged in the top region of the panel cover element. Consequently, the assembly process is then carried out in a modified corresponding way, i. e. the functional element is hooked in in the bottom region and snapped in in the top region.
