Abstract

The subject of invention is a device for protection of free-standing thermal household appliances, first of all kitchen-ranges and cooktop panels, from undesired consequences of out-of-time actions and from undesired children's actions. The household appliance (1) wears a sensor (2) installed at the upper exterior edge, which detects the presence of a person at an angle of between about 30 degrees and about 80 degrees upwards and wears besides a clock or a countdown clock ("timer") with a preselected turn-on time interval, preferentially for 15 minutes, which is turned on by the sensor (2). As soon as the sensor (2) detects the presence of a person (5), it turns on the clock and unlocks controls (3); when a person (5) moves off, the sensor (2) locks the controls (3) and the time or the time interval of the clock is started.

Description

DEVICE FOR THE PROTECTION OF INDEPENDENT THERMAL HOUSEHOLD APPLIANCES

The object of the invention is a device for protecting free-standing thermal household appliances, especially cookers and hobs, from the undesirable consequences of untimely interventions and from undesirable interventions by children.

The most common undesirable occurrences when using free-standing thermal household appliances, especially cookers and hobs, are that the operator, most often because he forgets, is untimely or. interrupts surgery too late. This results in the least burned food and dishes, and even a fire can be caused. Another cause is young children who touch the control buttons during play and change the operating conditions of the appliance uncontrollably. This possibility is especially present in the recent times, when some of the control functions of the appliances are implemented with touch sensors and the inadvertent and slight touch causes unwanted operation of the apparatus. The consequences may be the same as in the first case.

Known methods of key or code security that only allow the device to be controlled. There are also known solutions where devices have a timed disconnect or alarm. However, the applicant is not aware of devices for the protection of free-standing domestic thermal household appliances that would protect against the undesirable consequences of untimely interventions and against unwanted interventions by children.

The object and object of the invention is a device that will easily, reliably and without special interventions protect free-standing thermal household appliances, in particular cookers and hobs, from the undesirable consequences of untimely interventions and from unwanted interventions by children.

According to the invention, the problem is solved by a device for protecting free-standing thermal household appliances according to an independent patent claim.

-2 The invention is described on the basis of an embodiment and an illustration showing:

Figure 1: Design of the device with the sensor.

Household appliance 1 has a sensor 2 located on the upper outer edge. Sensor 2 may be a motion sensor, or. any type of sensor that detects the presence of a person at an angle between about 30 ° and about 80 ° upwards as indicated by arrow 6. In addition to said sensor 2, the apparatus according to the invention has an hour or so. a countdown timer, which has a pre-set start time of 15 minutes and is switched on by a sensor

2. When Adult 5 approaches the appliance 1, sensor 2 determines the presence, turns on the clock and unlocks the control buttons 3 of the appliance 1. The person 5 adjusts the operating conditions of the appliance via the buttons 3. new operating conditions of the appliance 1 are no longer possible. This is when the time or time begins to flow. clock interval. If the adult 5 does not appear within the range of sensor detection within the set time of switching on the clock, and therefore sensor 2 does not detect changes and does not set ("reset" or "restart") the clock at the beginning of a new switching interval, clock turns off the functions of appliance 1, that is, interrupts heating. If a person 5 appears in front of the appliance during the interval 5, the sensor 2 detects and sets ("reset" or "restart") an hour at the beginning of a new switching interval. If a small person, ie a baby, appears in front of the appliance 1, the sensor does not detect it, so it does not unlock the buttons 3 and set a new time interval. The device according to the invention therefore prevents uncontrolled changing of the mode setting and requires occasional monitoring, otherwise it switches off the device and prevents unwanted and harmful events.

In the embodiment, the preset time, or. an hour interval of 15 minutes; it is understandable that, within the scope of the invention, the operator has an adjustable time interval as well as that the interval is determined by a built-in automatics, which automatically lengthens the interval at low heating power. at high heating power the interval is shortened.

It is also understood that the invention includes both apparatus with electric and gas heaters, with the corresponding automatics of electrical design.

Claims (4)

Patent claims A device for protecting free-standing thermal household appliances, in particular cookers and hobs, against the undesirable effects of untimely interventions and against unwanted interventions by children, characterized in that the household appliance (1) has a sensor on the upper outer edge detecting the presence persons at an angle between about 30 ° and about 80 ° upwards, and having an hour or a. a countdown timer having a preset switch-on time of 15 minutes, preferably activated by a sensor (2), when the sensor (2) detects a person (5), switches on the clock and unlocks the control buttons (3) ; when the person (5) moves away, the sensor (2) locks the control buttons (3) and the time or time starts running. clock interval; if the sensor (2) detects a person (5) during the interval, sets a new time, or clock interval; after the interval has expired, the clock switches off the functions of the appliance (1), that is, it stops heating. Device according to claim 1, characterized in that the preset clock time is adjustable by the operator. Apparatus according to claim 1, characterized in that the preset time of the clock is adjustable by an automation device which automatically lengthens the interval at low heating power, or. at high heating power the interval is shortened. Apparatus according to the preceding claims, characterized in that it is an appliance with electric or gas heaters, with the appropriate automation of electrical design.
