Definitions
- the invention relates to a range hood with a control panel assembly to which switching elements are adapted to set the operating parameters.
- a control unit comprising switches arranged sequentially on a panel is utilized to adjust the operation modes of the functions of the range hood such as fan suction and lighting.
- the control unit has sequential switches mounted on the panel so as to be accessible externally. There is a mechanical push button on each of the switches.
- An integrated module in which switches having mechanical buttons are located, for mounting the control unit to the range hood is supported against the application of force in the direction of pressing the mechanical buttons that extend from the inside to the outside by being fixed in a mounting opening on the panel.
- control panel assembly comprises a housing; a printed circuit board inside the housing; a switch film which is formed integrally into a transparent cover mounted for covering the front portion of the housing and for conductivity; a conductive layer provided on thereof with a bolt located on the front face of the printed circuit board; and male and female coupling parts to couple the housing to the transparent cover.
- the housing defines the exterior appearance and a plurality of support extensions extend from the inside out. The support extension is fitted by securing the printed circuit board by means of the connection elements such as fastener.
- the object of the invention is to allow direct mounting of the mechanical switches of the control assembly to the glass panel of the range hood.
- the invention provides a range hood comprising a glass panel arranged on a body in an externally accessible manner wherein the body is reaching to an exhaust chimney and is confining an interior chamber; an opening provided on the glass panel so that reaching to the interior chamber; a plurality of movable push button next to each other extending through the opening; and a control assembly having a casing holding the buttons such providing support from behind and mounted to the glass panel by the inner wall thereof.
- the range hood is also comprising a cover having corresponding holes that are attached to the outer wall of the glass panel along a shielding portion from the rear side and arranged to surround each button without preventing the movement of travelling.
- the button moves from the opening in the axial direction through the cover hole towards the interior chamber and reaches a corresponding switch equipped in the body, activating it in a triggering manner.
- various functions (suction, lighting) of the range hood are activated or deactivated by pressing the button.
- the cover hide the opening, it prevents a foreign substance from accessing the interior chamber from the outside.
- the cover is mounted or removed for service by easily aligning the outer wall of the glass panel to the buttons that are mounted on the glass panel from the inner wall and extending from the opening to the outside.
- the cover can preferably comprise plastic, glass or metal material.
- a support plate is engaged to the opening through an intake portion and a holding element is extending between the support plate and the cover such that directly secure the cover on the support plate.
- the support plate provides a screwless mounting area for the cover in the glass panel when disposed in the opening, and the holding element allows the cover to be easily mounted on the glass panel by resting against the panel externally.
- the support plate includes a mounting portion that allows the casing being mounted on the glass panel from the rear wall.
- the holding element is in the form of a pin extending from the rear wall of the cover so as to shrink fit into a slot provided on the support plate.
- the cover is closed by covering the outer wall of the glass panel, allowing the cover to be directly mounted on the support plate over the opening.
- the pin can be formed on the cover to extend towards the support plate as well as in a possible embodiment, it can also be arranged to extend from the support plate towards the cover.
- pins the holding element disposed on the shielding portion wherein the pins are integrated are extending into the corresponding slots between the holes in a fitting manner. In other words, the pins extend through the holes in the cover. Thereby, providing the thin pins at intervals on the cover is sufficient to provide a fixing force to the cover.
- the support plate comprises a plurality of alignment opening which are opened thereon and arranged to be adjacent to the rear side, each aligned with a corresponding hole.
- the push button passes from the casing to the alignment opening and reaches the hole therefrom and extends out of the cover.
- the width of each alignment opening is arranged substantially equal to the corresponding hole. In this case, it is ensured that the buttons are guided in the support plate and move along their axes without deviation during pressing, especially when the widths of the alignment opening, and the hole are equal.
- the hole, alignment opening and button are aligned coaxially to each other, respectively.
- the button When the button is pressed, it travels straight in the axial direction and all the applied force is transmitted towards the casing.
- Switches are mounted in the casing to be placed behind each button. Thereby, the force applied by the axially travelling button directly reaches the switch.
- the cover is in the form of a flat plate resting against the outer wall longitudinally.
- opening is sealed.
- the cover extends in the same axis with the glass panel and the cleaning thereof is simplified.
- a compression spring is provided between each button and the casing.
- the compressive force of the compression spring is overcome and the button moves towards the casing from its rear end and when it is released, the button is pushed back towards its first position by the spring.
- a retaining strip is fixed adjacent to the back of each button and arranged larger than the hole such that rests against the inner wall by the compressive force of the compression spring when no external force is applied to the button.
- the retaining strip ensures that the space between the hole and the button is covered with the compression spring resting against the inner wall and supports the sealing.
- an extension shaft is secured from one end to the casing and from the other end to the button such that each adapted button extends from the hole by passing through corresponding alignment opening. The extension shaft helps to extend the button out of the casing from the opening.
