Definitions

  • the invention relates to an electrical household appliance according to the preamble of claim 1, comprising a main switch for switching the power supply on and off, which has a predetermined switch-on operating time during which it must be operated at least so that it moves from its off position to its Toggles on position.
  • Electrical household appliances for which the invention is applicable, are in particular free-standing or built-in cookers, ovens, hotplates, grills, coffee machines, dishwashers, washing machines and tumble dryers.
  • main switch is used in the context of the disclosure of the invention to represent any type of device or device by means of which a power supply can be switched on and off.
  • a “main switch” can be an individual switch or an electrical circuit which has electrical or electronic components and one or more buttons or sensors.
  • the sensors can be touch sensors or non-contact sensors, as already shown in the prior art.
  • An electrical household appliance is known from DE 42 07 772 C2.
  • This document shows a main switch in the form of an electrical circuit, which has as a control element a sensor (light sensor) which has to be actuated for a predetermined operating time in the range between 0.5 sec. And 1.0 sec.
  • a sensor light sensor
  • this switchover only takes place if only this one sensor is actuated, but not if other sensors (light sensors) adjacent to it are also touched at the same time or are covered by a saucepan or a rag that has been left lying and thereby reflect light. All sensors are located on a carrier plate under a glass ceramic plate that is transparent to the light from a light source.
  • the glass ceramic plate forms a hob that contains one or more cooking zones.
  • the adjustment period between the start of actuation and the actual switchover of the main switch from the off position to the on position can be achieved by an electrical time delay element, for example a resistance-capacitor series circuit with an electrical tap in between, or by an electrical circuit with a counter which digitally simulates the property of the resistance-capacitor circuit.
  • DE 295 120 593 U1 shows a hob in the form of a top hob or a built-in hob with a hob made of glass ceramic, which has several cooking zones.
  • An actuating device has touch switches or non-contact switches by means of which the cooking zones can be switched on and off and various temperatures or functions can be set.
  • the actuating device contains an on-off button as the main switch, which has a time delay in the range of one to five seconds when switched on. This is to prevent unwanted switching on, for example if you wipe the on / off button with a damp cloth for cleaning purposes.
  • the actuation period during which the main switch must be touched or pressed or actuated by finger proximity so that it changes from the off position to the setting is also a childproof lock. Young children run the risk of turning on the main switch, unobserved by an adult, and thereby switching on hobs, cookers and ovens. This can result in an operator burning their hand on hot stoves or even a fire.
  • the actuation time that is, the necessary dwell time of the finger at a main switch, which is designed in touch control control technology, until the actual activation of the household appliance is selected so that it represents a compromise between incorrect operation safety and simple, fast operation.
  • the operating time should be as long as possible.
  • the dwell time should be as short as possible.
  • an actuation time of z. B. typically about 0.5 sec.
  • the main switch was sometimes arranged in the rear area of the appliance, making it difficult for children to reach, which provided additional child safety.
  • the arrangement of sensor controls on cooktops in the front cooktop area is preferred, since this is ergonomically cheaper.
  • the arrangement of the main switch in the rear area of glass ceramic cooktops is technically and in terms of costs difficult because, for example, a separate circuit board, additional wiring and housing changes are required.
  • the main switch, or at least its control element can often be arranged only on one panel.
  • the object of the invention is to use simple means to minimize the risk of unintentional switching on of household appliances and the associated dangers.
  • the risk to children and the damage to property by children playing should be minimized by making the unsupervised commissioning of household appliances, in particular hobs, stoves and ovens more difficult.
  • This object is achieved according to the invention in that the length of the actuation time required to activate the main switch on the finished household appliance at the customer can be set by an operator using a time duration setting means provided for this purpose.
  • the actuation time for the main switch is selectable and adjustable by the customer according to the invention. No qualified specialist is required for this. This results in an expanded parental control. If, after an initial short actuation period of the household appliance, the actuation period of the main switch is extended, a child will take his or her finger away from the main switch after the earlier shorter actuation period, so that it does not switch from the off position to the on position. It is therefore expedient to deliver the household appliance to the customer with a fixed, preferably permanently programmed value as the minimum actuation period. This means that a safeguard against unintentional commissioning is available from the time of delivery given the household appliance. Depending on the desired embodiment of the household appliance, the customer can be provided with one, two or more longer operating times for selection.
  • the actuation time period can be freely adjustable by the customer in a certain time window, for example between 0.5 sec. And 5.0 sec., Depending on the embodiment, continuously or stepwise.
  • these setting options should preferably be implemented without additional hardware, for example, by using programs which are present in the household appliance for other functions anyway, for. B. software, e.g. B. by the setting directly by a key combination or a key actuation sequence taking into account the key actuation time and / or key location, or by the setting is realized by switching the household appliance into a programming mode if the household appliance contains one or more data processing programs as is customary today.
  • the time duration setting means mentioned in the context of this description of the invention can thus not only be implemented by additional elements, but are preferably implemented by changing the program of the programs used in the household appliance.
  • the invention has the following advantages in particular: Increasing child safety, since children are unlikely to leave their fingers in the same place for several seconds while playing.
  • the operating time is variable, so that after the critical age of the children has elapsed, the operating time can be reset to the short, initial value, which is more convenient for the operator.
  • the invention can be implemented in a household appliance without additional hardware costs. Main switches in touch technology design are becoming more and more popular compared to mechanical main switches and are particularly well suited for realizing the invention.
  • the invention is of particular interest for cooking appliances because, due to the working environment, there are high demands for ease of cleaning, which, because of the possible closed surface of the hob, leads to an increasing use of touch sensors and which can also be used to implement the invention, with other functions existing touch sensors also for the invention can also be used.
  • the danger to health (burns) and damage to property (house fire) is very high if the appliance is left unsupervised by children, especially with cooktops, and there can be devastating consequences.
  • the accessibility to the main switch for children need not be restricted.
  • the main switch can be placed at an ergonomically convenient location for use by an adult without losing child safety.
  • the period setting means for setting the actuation period according to the invention can be adjustable electrical components such as adjustable electrical resistors, adjustable capacitors; or data processing programs or parts thereof on which the actuation time period can be variably programmed and called up or in which actuation time periods can be permanently stored and called up; and they can include manual controls and / or be remotely controlled, such as over telephone lines, wireless radio, internet, etc.
  • the time duration setting means can be designed for the stepless or gradual adjustment of the actuation time period.
  • the control element or the control elements of the main switch can be buttons or sensors, which are preferably designed in touch control technology. It can be touch sensors or non-contact sensors.
  • FIG. 1 schematically shows an electrical household appliance according to the invention
  • Fig. 2 shows schematically a further embodiment of a household appliance according to the invention.
  • the electrical household appliance 2 shown schematically in plan view in FIG. 1 is, for example, a stove with a ceramic plate 4, under which there are electrical heating elements 6 and 8 in cooking zones 7 and 9, respectively. They are identified by sensors 6-1 and 8- 1 selectable. Its heating strength can be adjusted by further sensors, for example a plus sensor 10 and a minus sensor 12.
  • the control of the heating elements 6 and 8 of the cooking zones 7 and 9 takes place via a data processing unit 14 of a control device 16.
  • the power supply of the control device 16 and the heating elements 6 and 8 takes place via a main switch 18 which can be switched on for the supply of current 20 or for current interruption can be switched off.
  • the main switch 18 is actuated by an operating element 22, preferably a button or sensor.
  • the sensor can be a non-contact sensor or a touch sensor.
  • the main switch 18 has a predetermined switch-on actuation period during which the control element 22 must be actuated by a person, for example by approaching or touching a finger, so that it switches from its switch-off position to its switch-on position.
  • the length of the actuation period on the finished household appliance can be adjusted by an operator by means of a period setting means provided for this purpose.
  • One or more of the existing control elements 22, 24, 6-1 and / or 8-1 in combination with the control device 16 and its data processing unit 14 serve as setting means for this.
  • a program of the data processing unit 14 contains retrievable values for different actuation times.
  • the program can be programmed by one or more of the control elements to generate a desired change and setting of the actuation time period.
  • the various actuation times are called up and programmed or set by a predetermined actuation sequence of one or more of the control elements 22, 24, 6-1 and / or 8-1, depending on what the household appliance is designed for. No additional hardware or software is required.
  • an additional duration setting means can be provided in the form of hardware 24, e.g. B. a switch, button or other sensor on which the actuation period is manually adjustable and adjustable in the data processing program, or according to another embodiment without Data processing program directly in the main switch 18.
