Definitions

• the present invention relates to a control panel for an electrical appliance, for example for a refrigeration appliance.
• Modern electrical large household appliances such. As refrigerators, cookers or the like., Especially those that are designed for use as a free-standing device, usually have a cuboid housing, on the front of a door is attached.
• a control panel In a narrow section of the front panel above the door, a control panel is housed, on which a number of controls, such as switches, controls and display elements, are housed for operating the device and for displaying a current operating state.
• a control panel In an inner part of the control panel an electronic board is installed to control the controls.
• the object is achieved by a control panel for an electrical appliance, with an open on one side receiving chamber into which an electronics board via the open side insertable and supported on the open side support surfaces is fixed, at least one side wall of the receiving chamber carries at least a first spring tongue which intersects a plane defined by the support surfaces for the electronics board.
• the electronic board can initially be very easily inserted into the receiving chamber, since the support surfaces form a stop for a defined installation level of a support plate of the board.
• the first spring tongue can be easily pushed aside.
• the spring tongue can serve as a stop that fixes the position of the electronic board in the interior despite the small dimensions of the latter.
• the first spring tongue is deflected by an edge of the electronic board parallel to the wall carrying it.
• the first spring tongue can protrude from the wall and a lateral
• Form stop for the electronics board If necessary, can be formed by the arrangement of a plurality of first spring tongues at certain intervals along the mounting plane of the electronic board, a number of stop positions, which, depending on
• Size of the electronic board can be sunk by the edge of the board into the wall or can block a side edge of the board.
• the electronics board can be inserted without the aid of tools from the open side into the receiving chamber, without the first spring tongue is an obstacle.
• the electronic board advantageously carries at least one wall of the receiving chamber at least a second spring tongue, which is connected between the mounting plane and the open side with the wall and has a plane facing the mounting plane free end.
• the second spring tongue can initially retreat into a plane of the wall.
• the second spring tongue can project from the open side over the lower edge of the support plate and lock it in a stop position.
• a plurality of second spring tongues can be arranged both on an upper and lower wall, so that the electronic board can be firmly locked from several sides.
• a decorative panel covers a front of the receiving chamber.
• a decorative panel corresponding to the functional scope of the device with provided operating elements can be placed on the receiving chamber, so that no specific adaptation of the receiving chamber to the device model is required.
• FIG. 1 is a simplified representation of a control panel according to the invention with a built-in first electronic board, seen from behind.
• FIG. 2 shows the illustration from FIG. 1, wherein a second, longer electronic circuit board is installed;
• Fig. 3 shows the illustration of Fig. 1, wherein a third shorter electronic board is installed.
• Fig. 1 shows a control panel 1 for an electrical appliance in a simplified representation, viewed obliquely from behind.
• the control panel 1 is provided for installation on a front side of the electrical appliance above a door.
• the control panel 1 comprises a narrow, elongated frame 4, a receiving chamber 2, which has an elongated cuboid shape, and a plurality of electronic components supporting first electronic board 3, which is installed in the receiving chamber 2.
• the frame 4 is open at its in Fig. 1 facing away from the viewer front side; a not shown, the expert from DE 100 37 250 A1 familiar, specific for the model of the electrical appliance decorative plate with windows or passages for controls and display elements of the electronic board 3 closes the front of the frame. 4
• the receiving chamber 2 has four side walls which project perpendicularly from a rear side of the frame 4 and an open back side 20, which is delimited by the side walls, through which the first electronic board 3 can be inserted into the receiving chamber 2 for mounting.
• the first electronic board 3 occupies about two-thirds of the length of the receiving chamber 2 and abuts along three edges on inner surfaces of the side walls of the receiving chamber 2.
• the upper and lower side wall 26 and 22 of the receiving chamber each carry on its inside a plurality of narrow, rib-like, in an interior of the receiving chamber 2 perpendicular projecting support surfaces 21, which are arranged parallel to the back 20 limiting rear edge of the side wall 22 and a front Form stop for the first electronic board 3, so that an installation level 24 of the first electronic board 3 is defined by the support surfaces 21.
• Only one of the support surfaces 21 on the lower side wall 22 is shown in FIG. 1, so it is easy to understand that from the first electronic circuit board 3 concealed support surfaces on the side walls 26, 22 in sufficient number or of appropriate shape and extent must be present in order to clearly determine the position of the board 3.
• a first spring tongue 23 is further arranged, which is connected near the rear edge of the side wall 22 with the side wall 22 and projects from there obliquely upward from the side wall 22 into the interior of the receiving chamber 2 inside.
• the first spring tongue 23 intersects the installation plane 24 of the first electronic board 3.
• the first spring tongue 23 can be deflected towards the side wall 22, wherein the first spring tongue 23 can retreat completely into the side wall 22 into an opening of the side wall 22 corresponding to its shape. Since the first spring tongue 23 intersects the installation level 24 in its relaxed position, the first spring tongue 23 blocks a lateral edge 32 of the first electronic board 3, so that the latter is held firmly at its installation position on all four edges.
• a further first spring tongue 23 ' is partially visible, which is deflected by a lower edge 31 of the first electronic board 3, and in this case completely back into the side wall 22.
• the first spring tongues 23, 23 ' are positioned along the mounting plane 24 so as to divide the side wall 22 into three sections of approximately equal length.
• the first electronic board 3 is held by a plurality of arranged on the side walls 22, 26 second spring tongues 25 which also project in a relaxed position of the side wall 22 and 26 in the interior of the receiving chamber 2 and flexibly deflected can be, so that they recede into correspondingly shaped recesses in the side wall 22 and 26 into it.
• the second spring tongues 25 are connected to the side wall 22 and 26 near the rear edge. A free end of the second spring tongues 25 faces the installation plane 24 of the first electronic circuit board 3 and forms a rearward stop for the installation position of the first electronic circuit board 3.
• the second spring tongues 25 are first deflected by the lower edge 31 and the upper edge of the electronic board 3 and soft in the side wall 22, 26 back. As soon as the first electronic circuit board 3 has reached its installation position, the second spring tongues 25 spring back into their relaxed position, so that the electronic circuit board 3 is firmly locked.
• Fig. 2 the same receiving chamber 2 is shown as in Fig. 1, wherein instead of the first electronic board 3, a second electronic board 3a is installed, which occupies the entire length of the receiving chamber 2.
• the second electronic board 3a and the first spring tongue 23 is deflected from its basic position and is sunk into the side wall 22 in order to allow the installation of the longer electronic board 3a.
• the support surfaces 21 are all covered in this illustration by the second electronic board 3a.
• FIG. 3 shows the receiving chamber 2 with a built-in third electronic board 3b, which occupies only about one third of the length of the receiving chamber 2 and rests with an upper and a lower edge on the inner surfaces of the lower side wall 22 and the upper side wall 26.
• the lateral edge 32 and an opposite lateral edge 33 are respectively blocked by one of the first spring tongues 23, 23 ', which protrude from the side wall 22 in their relaxed position.
• first spring tongues 23, 23 'and their positioning along the mounting plane 24 may be changed.
• the support surfaces 21 may be varied in their number and arrangement along the mounting plane 24.
