Definitions

  • the invention relates to a toaster, with at least one ToastSchacht, an ejection device for Toastgut and a heater for the interior of the Toastschachts.
  • Toasters are known from public prior use. With a usual toaster toast toast bread or similar flat toast is placed in a toast and toasted for an adjustable period of an electric heater. Upon completion of the toasting process, it is ejected from a generally spring-actuated ejector.
  • the invention has for its object to create an easy to handle and versatile toaster fen.
  • the invention achieves this object by the following features: a) the heating device is gas-operated, b) the gas supply for operating the heating device is integrated in the toaster.
  • a toaster according to the invention is intended for household use and has at least one NEN toast shaft.
  • the toast tray is preferably loadable from above and preferably has dimensions that allow the inclusion of conventional toast bread.
  • the toaster according to the invention is preferably designed for simultaneous toasting of 1 to 8, preferably 2 to 6, more preferably 2 or 4 slices of toasted bread.
  • the ejection device for toast material is used for loading and ejecting the toast. It is preferably a basically known in the prior art ejection device in which the Toastgut is lowered into the Toastschaft by depressing a lever and preferably ejected spring-actuated after a predeterminable period.
  • the heater for the interior of the toast shaft is gas-operated according to the invention.
  • the heat generation for the Toastvorgang thus takes place by burning gas, the gas supply is integrated into the toaster.
  • integrated means that the gas supply is permanently connected to the toaster, so that the toaster always effectively carries its gas supply with it.
  • the toasting shaft preferably has side walls made of thermally conductive material. It is further preferred that the
  • Heater has at least one gas burner acting on the side walls.
  • the gas burner may have an open gas flame or, alternatively, perform catalytic combustion.
  • the surfaces of the toast to these heated side walls so that a uniform heat transfer from the side walls to the toast takes place.
  • the inventive design of the side walls of heat-conductive material facilitates the dissipation of the heat of the gas burner and their substantially uniform distribution over the entire surface of the toast.
  • the toaster preferably has at least two gas burners arranged opposite one another on two sides of a toast shaft.
  • the side walls may additionally have gas passage openings. In this way, an additional heating of the Toastguts done by the flow of hot combustion gases into the Toastschacht.
  • the gas passage openings need not be evenly distributed over the surface of the side walls.
  • the side walls may preferably have a larger number of gas passage openings per area.
  • the side walls may preferably have a reduced number of gas passage openings per area or even no gas passage openings. In this way, a more even distribution of the heat over the entire surface of the Toastguts can be achieved.
  • the side walls On the side walls, means may preferably be arranged which serve to guide the hot combustion gases flowing through the gas passage openings. In this way, the combustion gases can be directed to areas where the toast is less well supplied with heat. As a result, an additional improvement of the heat distribution over the entire surface of the Toastguts is achieved.
  • the resources allocated to the management of the gas Can serve openings through which combustion gases flowing through can preferably be arranged horizontally sheet metal struts.
  • the Toastschacht also reflector walls, which are arranged from the point of view of Toastguts behind the side walls. The reflector walls are preferably formed so as to improve the uniformity of the heat distribution over the entire surface of the toast. In areas where less heat is needed due to the design
  • the reflector walls can be arranged closer to the toast. In areas in which more heat is given off to the toast material due to the design, the reflector walls can be arranged further away from the toast material.
  • the gas supply has at least one interchangeable and / or refillable gas tank.
  • the gas used is usually a liquefied gas such as propane, butane or a mixture thereof.
  • the gas tank is designed as an exchangeable gas cartridge.
  • the gas tank can be arranged below the toast shaft. It can be accessible, for example, through an opening in the bottom of the toaster and is thus easily replaceable on the one hand, and on the other hand protected against rising heat during operation of the toaster.
  • the gas tank can also be arranged laterally of the toast shaft. It can then be accessible, for example, through an opening in the sidewall of the toaster.
  • the ejection device is coupled to a gas valve and an ignition device.
  • the insertion of Toast by means of the ejector thus opens the gas supply to the gas burner and actuates the ignition.
  • the ignition device can operate, for example, battery-operated, preferably a piezoelectric ignition, the piezoelectricity can be generated by the operation of the ejector.
  • the gas valve may be part of the structure of the toaster and actuated by the insertion of the ejector. Alternatively, it is possible to use a gas valve present in the gas cartridges. Gas cartridges usually have a valve that can be opened by pressure in the region of the gas outlet opening of the cartridge.
  • the toaster may preferably have a first temperature sensor, which causes a shutdown of the gas supply upon reaching a certain maximum ambient temperature (T max ).
  • the first temperature sensor is preferably arranged in the vicinity of the cartridge. In this way it can be achieved that the cartridge is not heated above a certain temperature.
  • the temperature sensor can also be arranged in the vicinity of particularly sensitive plastic parts.
  • the temperature sensor may be any suitable one known in the art Temperature sensor act.
  • the temperature sensor is designed as an electrical temperature sensor.

  • the first receiving element may be a substantially cylindrical sleeve, in which the wall of the lateral surface have recesses.
  • a second substantially cylindrical receiving element comprises an insulating material and is dimensioned such that it comprises the first receiving element in a form-fitting manner.
  • These recesses are so dimensioned and spaced that they can be brought by a rotational movement of the first and / or second receiving element about a common longitudinal axis with the recesses of the first receiving element optionally completely, partially or not at all.

  • the temperature sensor may be a pivotably mounted temperature sensor which is designed such that it can be operated at a fixed predefined temperature. switches off. Depending on the pivot position, the temperature sensor is closer to or farther from the toast material or the flame. The closer the temperature sensor is to the flame, the sooner it switches off and thus the lower the degree of browning achieved.
  • the first and second temperature sensors do not have to be two different temperature sensors, but rather, both temperature sensors can also be identical. In this case, T must be the same from T max or smaller. A coordination of these two temperatures successive can be achieved by a suitable positioning of the temperature sensor in the toaster or by the design of the insulation.
