## Abstract

A cooling or freezing device includes an ice-making tray having a plurality of ice-piece-producing cavities distributed over at least two rows of cavities running parallel to one another. The device further includes a cold air supply system which provides a cold air stream which flows beneath the ice-making tray along the rows of cavities. There is additionally provided a temperature sensor unit which is inserted into a gap formed on the underside of the tray between a pair of adjacent ice-piece-producing cavities. The pair of cavities is formed by two ice-piece-producing cavities which, as seen in the direction of flow of the cold air stream, are the last ice-piece-producing cavities of two adjacent rows of cavities.

## Claims

### Claim 1

A cooling or freezing device comprising:
an ice-making tray having a plurality of ice-piece-producing cavities distributed over at least two rows of cavities running parallel to one another, the ice-making tray having a plurality of cavity walls to delimit each of the plurality of ice-piece-producing cavities;
a cold air supply system which provides a cold air stream which flows beneath the ice-making tray along the rows of cavities; and
a temperature sensor unit which is inserted into a gap formed on the underside of the tray between a pair of adjacent ice-piece-producing cavities, wherein the pair of cavities is formed by two ice-piece-producing cavities which, as seen in the direction of flow of the cold air stream, are the last ice-piece-producing cavities of two adjacent rows of cavities;
wherein the temperature sensor unit comprises a temperature sensor and a sensor housing, the sensor housing being fixed to the underside of the ice-making tray, the temperature sensor being accommodated in the sensor housing and having a rod-like main sensor portion which is in direct contact with a cavity wall of each of the pair of adjacent ice-piece-producing cavities.

### Claim 2 (depends on 1)

The cooling or freezing device according to claim 1, wherein the cold air supply system comprises a cold air guide trough arranged beneath the ice-making tray, which trough delimits a cold air channel for guiding the cold air stream.

### Claim 3 (depends on 1)

The cooling or freezing device according to claim 1, wherein the ice-making tray is longer than it is wide, and the cold air stream flows along the ice-making tray in the longitudinal direction thereof.
