Coffee machine comprising a continuous heater
View Patent ↗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.
1. A coffee machine for preparing coffee using coffee pads, which comprises a continuous heater provided with a water-guiding pipe that is thermally connected to two heating rods provided at opposite sides of the pipe by means of contact surfaces, and a pump for transporting water through the continuous heater, wherein the all of the contact surfaces of the pipe and the heating rods are flat,
wherein the pipe has ends into which hose-like flexible tube connecting pieces of a water supply and a water exit are inserted, and wherein the connecting pieces are made of plastic and comprise securing means for securing the continuous heater on a housing of the coffee machine, and holders provided on the securing means, the holders being configured to receive additional components of the coffee machine.
2. The coffee machine according to claim 1 , wherein the pipe and the two heating rods are held together by a sleeve.
3. The coffee machine according to claim 2 , wherein a temperature sensor is disposed adjacent the sleeve.
4. The coffee machine according to claim 1 , wherein the connecting pieces are provided with seals.
5. A coffee machine for preparing coffee using coffee pads, the coffee machine comprising:
a continuous heater provided with a water-guiding pipe;
two heating rods provided on opposite sides of the pipe and thermally connected to the pipe by corresponding contact surfaces, wherein all of the contact surfaces between the two heating rods and the pipe are flattened; and
a pump cooperable with the continuous heater and transporting water through the continuous heater,
wherein the pipe has ends into which hose-like flexible tube connecting pieces of a water supply and a water exit are inserted, and wherein the connecting pieces are made of plastic and comprise securing means for securing the continuous heater on a housing of the coffee machine, holders provided on the securing means, the holders being configured to receive additional components of the coffee machine.
6. The coffee machine according to claim 5 , wherein the pipe and the two heating rods are held together by a sleeve.
7. The coffee machine according to claim 6 , wherein a temperature sensor is disposed adjacent the sleeve.
8. The coffee machine according to claim 5 , wherein the connecting pieces are provided with seals.
