The inner lining (10) consists of an upper wall (12), an adjacent side wall (14) and an opposite side wall (15) and the side walls (14, 15) from below. it is in a monolithic form in the form of a bathtub with a lower wall (16). Inner lining (10) It is manufactured with plastic blowing. The side of the inner liner (10) in the planar plate structure a sensor (20) is mounted on the rear wall (l 1) leaning against the wall (14).

The sensor (20) is circulating in the cooling chamber delimited by the inner lining (10). It measures the temperature of the cooling air and calculates the temperature it has obtained. transmits it to a control device (not shown) of the refrigerator. your back wall (11) on a hole (not shown) in the middle that opens to the refrigeration cycle. a fan (50) is mounted. A fan in the form of a wire grid (44) on the fan (50) its housing (40) is removable. One tooth of the fan housing (40) a radially extending curtain (32) is fixed to its edge (41).
