Description
Technical Field
The present invention relates to a control device for a household appliance. In particular, the invention relates to a control device with a touch screen.
Background
Household appliances such as a kitchen range can be controlled by means of a control device. The control means is connected to the user interface for scanning the user's prescription. For this purpose, the user interface comprises a display device in the form of a mobile phone, in front of which the touch sensor is mounted. The display device may output predetermined contents, and may display a control surface provided with a function, for example. Optionally, text prompting the function can also be displayed. If the user touches the control surface, the range is controlled according to the function.
Such a control device is not well suited for all household appliances. The display device is generally flat and requires a flat surface of the home appliance. However, in a toaster or a hand-held appliance, for example, only a very small flat surface is provided, so that only a very small or very small control surface can be displayed. Furthermore, the price of a display device is often strongly dependent on the size of its display surface, so that for household appliances only a very small display surface may often be realized for cost reasons.
Disclosure of Invention
The object of the present invention is to provide an improved technique for improving the operation of a household appliance. The invention solves this object by means of the subject matter of the independent claims. The dependent claims reproduce preferred embodiments.
The control device for a household appliance comprises: a display device having a predetermined display surface; a touch sensor with a predetermined scan surface; wherein the scanning surface at least partially covers the display surface; and a processing device for determining a position on the scanning surface at which the contact of the touch sensor is made. The scanning surface extends beyond the boundary of the display surface at least on one side of the display device.
The household appliance is preferably arranged to perform a function close to home. The household appliance may in particular comprise a kitchen appliance or belong to a white household appliance. The household appliance may comprise, for example, a washing machine, a washing and drying integrated machine, a hot roll wringer, an iron, an ironing station, a steam ironing board, a kitchen range, a stove, a range hood, a dishwasher, a cooling device, a stand mixer, a hand mixer or a stirrer. Further examples include a vacuum cleaner, optionally a robotic vacuum cleaner, an electric hand tool or an electric garden tool.
Since a touch sensor is used that extends beyond the display surface, a small display device can be used, which can reduce the cost for the control device. The display device is generally flat and may in particular have a surface made of glass. The invention also makes it possible to use a display device with a small display surface in a household appliance with a small flat surface. On the other hand, the touch-sensitive surface can be kept large, so that the operator with a large hand can also control accurately. When the touch sensor is touched, the display device may not be covered, and thus interactive control of the home appliance may be performed.
The touch sensor is preferably designed to be capacitive and can be applied to a flexible substrate, for example a polymer film. In other embodiments, there are other measuring principles of touch sensors designed, for example, as resistive or projected capacitive. The touch sensor is preferably flexible, so that it can also follow uneven surfaces of the household appliance. The touch sensor can thus be integrated with the household appliance in an improved manner and can be operated more ergonomically. It is generally preferred that the touch sensor is designed to be transparent and mounted at the user facing surface of the display device.
The processing means are preferably provided for carrying out the method described herein, either entirely or partly. To this end, the processing means may comprise a programmable microcomputer or microcontroller and the method may be in the form of a computer program product with program code means. The computer program product may also be stored on a computer readable data carrier. Features or advantages of the method may be used with the device and vice versa.
The display surface is preferably rectangular in shape, wherein the scanning surface can extend beyond the boundary of the display surface on at least two sides. The two sides may be opposite each other or offset by 90 ° relative to the display device.
The scanning surface is further preferably designed to be larger than the display surface. The dimensions herein refer to the surface area of the user facing surface, which can be expressed in units of area such as cm 2 or mm 2. In the case of a display device, the size of the surface preferably corresponds to the display surface or the portion of the display surface visible to a user; in the case of a touch sensor, the scanning surface or the part of the scanning surface that is provided to the user. The scanning surface may be larger than the display surface by a predetermined amount, for example, wherein the predetermined amount may be inferred from the average size of the user's finger. The scanning surface may for example protrude over the width of one or both fingers of the display surface on one side of this display surface, which may correspond to an amount of about 1.5-4 cm. In another embodiment, the scan plane is larger than the display plane by a predetermined value, for example, as large as 1.2-2.5 times the display plane. The scanning plane may be oriented symmetrically or asymmetrically to the display plane, depending on the application.
The control device may also comprise a circuit board, at which the display device and the touch sensor are mounted, whereby a separately manipulable unit may be created, which unit may be more conveniently transported or mounted at the household appliance. The circuit board may in particular have substantially the dimensions of the contact sensor or of its scanning surface. The cost per unit area for the circuit board may be significantly less than the cost for the display device.
The processing means may be arranged for determining contact in an area of the scanning surface beyond the boundary of the display surface and for controlling a predetermined function of the household appliance. The function may change a parameter that can be interactively shown on the display device. The parameter may include, for example, a desired processing power or temperature. The currently adjusted value for the variable can be output on a display device digitally, textually or graphically, for example.
The household appliance comprises the control device described herein. The features and advantages of the device can be applied to household appliances and vice versa. The household appliance may in particular comprise a kitchen appliance, such as a kitchen range, stove, range hood or dishwasher.
The home appliance may include a front panel at which the touch sensor and the display device are mounted. The front panel is preferably transparent and may comprise glass, for example. Furthermore, the front panel is preferably flat at least in the area of the display surface. The control device may be mounted partly or entirely on the side of the front panel facing away from the user. Thus, moisture or dirt can be reliably kept away from the control device. In one embodiment, the control device is firmly connected to the front panel, in particular by means of an adhesive or welding material. Dirt or moisture can be prevented from penetrating into the area between the control device and the front panel. The control means may form together with the front panel a unit that can be manipulated individually.
The method for controlling the home appliance by the user comprises the following steps: scanning the contact of the contact sensor; determining a location at which contact is made; determining that the location is in an area of the scan surface beyond a boundary of the display surface; and controls a predetermined function of the home appliance. The function may be selected or parameterized depending on the operating state of the control device or of the household appliance. The functions are preferably related to graphical content shown on the display device before or during the contacting.
In a first variant, the position is in a first predetermined region, wherein the function is controlled as a function of the representation output on the display device. In a second variant, which can be combined with the first variant, the position is in a second predefined region, wherein the function is controlled independently of the representation output on the display device.
Drawings
The present invention will now be explained more precisely with reference to the accompanying drawings, in which:
FIG. 1 is a schematic diagram of a control device;
Fig. 2 is an example of a control device; and
Fig. 3 is a flowchart for controlling a home appliance.
Detailed Description
Fig. 1 shows a diagram of an exemplary control device 100 for a household appliance 105. Some elements of the control device 100 are here staggered along the axis 110 in an exploded fashion for better understanding.
The control device 100 comprises a display device 115 with a display surface 120, a touch sensor 125 with a scanning surface 130 and a processing device 135 which can be provided for controlling the household appliance 105. The processing device 135 is preferably connected to a further processing device, sensor or actuator of the household appliance 105 by means of an interface 140. Optionally, a circuit board 145 may be provided at which the display device 115 and/or the touch sensor 125 may be mounted. The display device 115 and/or the touch sensor 125 may also be mounted at a panel 150, which may be, inter alia, a portion of a surface of the household appliance 105.
The panel 150 preferably encloses the control device 100 towards a symbolically shown user 160. Here, the panel 150 is preferably at least partially transparent in order to ensure visibility of the display device 115. The touch sensor 125 is preferably mounted on the side of the display device 115 facing the user 160 and is also at least partially transparent. The display device 115 and the touch sensor 125 can also be exchanged in their order, where the touch sensor 125 does not have to be transparent. In yet another embodiment, the panel 150 may also be between the touch sensor 125 and the display device 115, wherein the touch sensor 125 preferably faces the user 160. The circuit board 145 is generally opaque and may be located furthest from the user 160.
The display device 115 and the touch sensor 125 may be fixed to each other. Both elements can additionally or alternatively also be connected to the circuit board 145 and/or the panel 150. The connection may include electrical contact and mechanical fixation. The contact connection may comprise a plug connection or a soldered connection and the mechanical connection may also be made in a material-to-material manner, for example by welding or adhesive bonding.
The display device 115 and the touch sensor 125 are preferably designed in the manner of a touch screen. In this case, an operating element 165 can be displayed on the display device, which can be seen by the user 160. The operating element 165 can be assigned a predetermined function of the household appliance 105. If contact is detected in the region of the actuating element 165 by means of the contact sensor 125, the predetermined function can be implemented. The representation of the operating element 165 on the display device 115 may be changed in order to either give optical feedback by means of the detected contact or to display parameters that can be changed by means of the operating element 165.
It is suggested that the scanning surface 120 of the touch sensor 115 overlaps the display surface 12 of the display device 115 at least one side. In the illustration of fig. 1, the display device 115 is designed as a rectangle. The scan surface 130 of the touch sensor 125 may be beyond the boundary of the scan surface 130 at one side, two sides, three sides, or four sides. Here, the touch sensor 125 is necessarily neither rectangular nor completely covering the display device 115. In the embodiment shown, the scanning surface 130 of the touch sensor 125 is, for example, superimposed on both sides in the horizontal direction and in the vertical direction on the display surface 120 of the display device 115.
The circuit board 145 is preferably at least as large as the scanning surface 130 of the touch sensor 115 and is therefore mounted such that the touch sensor 115 does not overlap the circuit board 145 on any side. The scanning surface 130 of the touch sensor 125 is preferably configured such that it does not overlap the panel 150 in any direction.
Fig. 2 shows two exemplary embodiments of the control device 100 from the perspective of the user 160, respectively. Both embodiments illustratively include a panel 150. In both embodiments, the scan surface 130 extends beyond the boundary of the display surface 120 in at least one direction.
In the above figures, the scan surface 130 includes a first region 205 congruent with the front of the display surface 120 and at least one additional region outside the display surface 120. At the present time, the second region 210 is disposed to the left, the third region 215 is disposed to the right and the fourth region 220 is disposed below the display surface 120. Further, the fifth region 225 may be disposed at a lower left side of the display surface 120 and/or the sixth region 230 may be disposed at a lower right side of the display surface.
Some of the regions 210-230 may be assigned functions that are unrelated to the illustration on the display device 115, respectively, while other regions of the regions 210-230 may be assigned context sensitive functions that may be related to the illustration or the operational state of the home appliance 105. The fifth region 225 may be associated with, for example, an on/off function of the household appliance 105, wherein this function is not changeable. The sixth area 230 can then be associated in a similar manner, for example, with an interrupt function of the household appliance 105.
In the following figure, a portion of the display device 115 shows a bar 235, the user 160 may influence the length of which by touching the touch sensor 125 at a location and moving this location. The ends of the strips 235 may be offset parallel to the current contact position. Thus, analog or digital values can be entered, for example, a desired temperature on the oven or a desired heating power on the oven.
Fig. 3 shows a flow chart of a method 300 for controlling a household appliance 105. The method 300 can be run in particular on the control device 100 and is preferably controlled by the processing device 135.
In a first step 305, contact at a location of the scan surface 130 of the touch sensor 125 may be determined. In step 310, it may be determined whether the location is outside of the display area 130 of the display device 125. If this is not the case, then the usual control methods for touch screens can be implemented.
If the contact point is outside the display area 130, the function assigned to the point can be determined in step 315. The function may for example comprise switching on or off a household appliance, component or function, or also inputting parameters or requests. The determined function may be implemented in step 320.
