Abstract

The invention relates to an apparatus (1) for simpler sensing the temperature in roasting of coffee. The apparatus (1) is provided for roasting coffee beans and comprises: a chamber (10) in which coffee beans can be received for roasting, and a device (80) for roasting the coffee beans received in the chamber (10). The chamber (10) is delimited by at least a bottom (11) and a sidewall (12) extending from the bottom (11), wherein the sidewall (12) comprises an outer side (121) oriented to face away from the chamber (10), and wherein a temperature sensor (90) is provided at the outer side (121) of the sidewall (12) for sensing a temperature inside of the chamber (10).

First claim

1 . An apparatus for roasting coffee beans, the apparatus comprising:
a chamber in which coffee beans can be received for roasting, and a device for roasting the coffee beans received in the chamber, wherein the chamber is defined by at least a bottom and a sidewall extending from the bottom, wherein the sidewall comprises an outer side oriented to face away from the chamber, and wherein a temperature sensor is provided at the outer side of the sidewall for sensing a temperature inside of the chamber.

2 . The apparatus according to claim 1 , wherein the chamber has a height up to which the chamber can receive the coffee beans in the chamber, wherein the temperature sensor is arranged at or below this height.

3 . The apparatus according to claim 1 , wherein the outer side of the sidewall comprises a recess, and wherein the temperature sensor is at least in part arranged in the recess.

4 . The apparatus according to claim 3 , wherein the recess is arranged to form a protrusion on an inner side of the sidewall, wherein the inner side is oriented to face to the inside of the chamber.

5 . The apparatus according to claim 4 , wherein the protrusion is arranged to come into direct contact with the coffee beans received in the chamber.

6 . The apparatus according to claim 3 , wherein the recess is formed by an embossing in the sidewall.

7 . The apparatus according to claim 1 , wherein the temperature sensor is arranged to transmit a first signal related to the sensed temperature for displaying the sensed temperature, such as for displaying the sensed temperature on a user interface or display unit and/or for displaying the sensed temperature on user device, which is wirelessly connected to the apparatus or temperature sensor, and/or wherein the temperature sensor is arranged to transmit a first signal related the sensed temperature for determining the presence of the chamber based on the sensed temperature and/or electrical resistance.

8 . The apparatus according to claim 1 , further comprising a control unit configured to control the device for roasting of the coffee beans, preferably based on the transmitted first signal of the temperature sensor and/or based on a second signal related to a roasting temperature sensed by a further temperature sensor of the apparatus, wherein the control unit is preferably configured to determine the presence of the chamber based on the received first signal, and to avoid roasting of the coffee beans by the device upon receipt of no first signal or the first signal exceeding or falling below a defined threshold value or range.

9 . The apparatus according to claim 1 , wherein the apparatus is configured to apply a correction factor to the temperature sensed by the temperature sensor.

10 . The apparatus according to claim 1 , wherein the apparatus further comprises a user interface or a display unit preferably configured to display the sensed temperature based on the transmitted or received first and/or second signal, and/or wherein the apparatus further comprises a communication interface for wireless communication with a user device such as a smartphone.

11 . The apparatus according to claim 1 , further comprising a receptacle, wherein the receptacle comprises the chamber.

12 . The apparatus according to claim 11 , wherein the receptacle comprises a handle, wherein the handle is arranged such that at least in a plan view of the receptacle the handle covers the temperature sensor.

13 . The apparatus according to claim 1 , wherein the temperature sensor is fixedly arranged with respect to the chamber so that the temperature sensor moves together with the chamber when the chamber is moved, such as when the receptacle is detached, or wherein the temperature sensor is arranged to remain stationary when the chamber is moved, such as when the receptacle is detached.

14 . The apparatus according to claim 1 , wherein the device is arranged to generate a current of air in order to agitate the coffee beans received in the chamber, and/or wherein the device is arranged to generate a heated current of air to roast the coffee beans received in the chamber.

15 . The apparatus according to claim 1 , wherein the apparatus is a home appliance apparatus.
