摘要:
A coffee machine for preparing coffee, especially based on coffee pads, includes a continuous heater provided with a water-guiding tube that is thermally connected to at least one heating rod via at least one contact surface. A pump transports water through the continuous heater. The contact surface is embodied in such a way that it is flat between the tube and the at least one heating rod. The coffee machine structure provides a simple and cost-effective solution for a continuous heater, and ensures good heat transfer.
摘要:
A coffee machine comprising a holder for receiving a coffee pad. The holder is provided with an opening for inserting a coffee, and at least one outlet, a carrier for receiving the holder and a holder cover which can cooperate with a sealing surface of the holder, such that a pressure chamber surrounding an inserted coffee pad can be formed. In order to reduce the production costs of the coffee machine and to maintain and/or improve operability, the holder is embodied as a single part.
摘要:
A coffee machine comprising an instantaneous electric heater for heating water, which is transported from a storage tank and conducted under pressure after the heating process into a brewing chamber to prepare the coffee, said chamber comprising an outlet nozzle for discharging the prepared coffee. The machine also comprises at least one sensor for recording an electric measured value that correlates to the temperature of the heated water and a control system for controlling the pump output of the pump and/or the heating output of the instantaneous heater in accordance with the measured value. The device permits a blockage of the nozzle to be identified and safely removed. The control system shuts off the pump output and/or the heating output if the measured value exceeds predefined thresholds and blocks a restart of the pump output and/or heating output for a specified blocking period by activating blocking elements.
摘要:
Heating device with a heating element of a material with positive temperature coefficient, of which two opposite sides are contacted by planar electrodes and give off the heat produced through the electrodes and planar sheets of insulating material covering the same to two heat-absorbing surfaces of a heater. The sheets of insulating material are coated on their side facing the heating element over a large area with a solder and are soldered to the electrodes. This insures permanent good heat transfer between the electrodes and the insulating material covering them. The firmly joining together of the heating element and the sheets of insulating material to form a structural unit facilitates the assembly, i.e., the installation of the heating device.
摘要:
A coffee machine, especially an espresso machine, comprising a brew chamber provided with at least one coffee outlet, a height-adjustable spout for ejecting coffee, and an impact surface arranged upstream of said spout. The aim of the invention is to ensure that, despite the fact that the height of the spout can be adjusted, the coffee produced is of a consistently high quality. To this end, the impact surface is arranged at a fixed distance from the coffee outlet, coffee passing through said outlet hitting the impact surface and being guided to the spout from the impact surface.

摘要:
A coffee machine for preparing coffee, particularly on the basis of coffee pads, comprising a continuous flow heater which is fixed in a housing and provided with a tube for guiding water. In order to fix the continuous flow heater and, preferably, other components in the coffee machine in a low-cost and secure manner, the at least one flexible tube connecting piece is provided with receiving elements for integrating additional component parts of the coffee machine.
摘要:
A method for preparing hot beverages in a hot beverage machine by possibly repeatedly pumping a specific quantity of water from a water tank into a heating device, heating the quantity of water, pumping the heated quantity of water out of the heating device into a brewing chamber and possibly at the same time pumping a further quantity of water out of the water tank into the heating device, brewing a brewing substance contained in the brewing chamber to produce a hot beverage, and finally converting the quantity of water last pumped into the heating device completely into steam in a controlled manner for forcing liquid out of the entire line system downstream of the heating device.
摘要:
A method for controlling heating processes in a coffee machine which is particularly suitable for preparing coffee on the basis of coffee pads. The coffee machine comprises a continuous flow heater and a pump used to convey water through the continuous flow heater. According to the inventive method, the temperature is measured in the region of the continuous flow heater and/or water which is conveyed by the pump. In order to avoid steam overpressure and to ensure a sufficient, constant temperature during the entire steeping process, the amount of water which is conveyed by the pump is influenced according to temperature. The invention also relates to an electronic control device.
