WO2009062329A1 - Power-saving, environmentally friendly, electric hotplate with separate, integrated heating elements, which can be switched on and switched off separately, with integrated timers or time switches - Google Patents

Abstract

Power-saving, environmentally friendly, electric hotplate for use in households, with which meals can be taken at different times, characterized in that this hotplate has various heating parts which can be heated independently of one another, has a common power supply, but is equipped with separate integrated timers or time switches for each heating sector which allow the firing duration of the heater in the diverse heating sectors to be split or to be matched to requirements or to the desired meal times, as a result of which unnecessary power consumption, unnecessary radiation of heat and uncomfortable overheating of the homes is avoided. In addition to the cost saving made as a result of power not being required, climatic heating is also reduced and a contribution is made to environmental protection by this hotplate.

Description

 Energy-saving, environmentally friendly, electric heating plate with separate, integrated heating elements, separately switched on and off, with built-in timers or time switches.

In addition to cookers and ovens, hotplates and pancakes are offered for electric cooking. Electric hotplates are designed to keep food warm and ready to serve at the desired time. Basically, this can be achieved with thermostats and set at estimated low temperature hotplates. This has the disadvantage that the prepared food can burn. Electric hotplates rule this out, because the temperature is technically set only for keeping warm. Such electric hot plates have the disadvantage that they are offered only with a single heating element, unnecessarily consume energy under the usual circumstances and also radiates unnecessary heat, which runs counter to efforts to reduce global warming, contrary. The present invention has for the purpose of avoiding unnecessary electric power consumption, to prevent senseless global warming, which can lead to an uncomfortable overheating of the apartments. It is also possible through these, at different meal times, to remove food from the hot plate in the desired heat and turn off individual parts of the hot plate, if they have become unnecessary. This is achieved in that in the heat retaining plate at least two independent heaters, or heat elements are installed, the energy supply is from a common power source and the top of the heat plate is divided into at least two visible shelves, or sectors. Indicator lamps indicate which plate sectors are heated. The surface of the sector is the same color, divided by designs, hyphens, etc. recognizable dissolved. Each heatable plate sector is equipped with a switch, thermostat, timer or timer, depending on the model of the heating plate. Thus, the desired burning time and heat of the respective plate sector is determined in advance and when the heat of the disk sector concerned switches off after the set time, while the remaining parts of the hot plate remain heated, so that the other still prepared food are kept warm for later to be performed meal time. This ensures that various meals at different times of a single hot plate, can be removed warm. The timer or the set time switch of the respective used heat plate sector determines when the power supply and thus the heat radiation ceases. To avoid accidentally changing the switch, the timer, or the thermostat, the hotplates may be equipped with covers or other means integrated therein. The shutdown of the power supply after use of a heat sector, or partial parts of the heat plate cause the saving of energy and avoid unwanted, wasted heat, which with this invention makes a contribution to environmental and climate protection is achieved. In addition, the electricity costs of the consumer are considerably reduced.

Fig. A shows an electric heating plate with two separate (1 + 3) heating surfaces. These can be marked differently by design, color or dividing lines (2) in the middle of the top of the board. The power is supplied by means of a cable (4); a control lamp (5) separately for Plattenheizsektor, independently installed (integrated) indicates whether it is under power, or in operation. Switches (6) allow the power supply to be interrupted independently for each area sector. Integrated into the hotplate, for each surface sector, a timer, timer, or thermostat (7) is a lidded or capped capping device (8) to prevent inadvertent tampering

Claims

Claims: 1. Heat plate designed such that the surface of independent heating elements are warmed and these plate parts have a common power supply. 2 claim according to claim 1 designed so that the each heated surface sector separately switched on and off, 3. claim according to claims 1 - 2 designed such that they are each equipped with an integrated timer or a power timer. 4. claim, according to claims 1 - 3 designed such that switches, timers and the integrated timer are each covered with a fixed to the plate top cap, etc., to prevent inadvertent manipulation of the same. 5. Claim according to claim 1 designed so that is visible to control lamps, - which plate parts are in operation, or heated. 6. Claim according to claim 1, characterized in that the sectors of the surface of the hot plate are divided in color or marked by markings.
