PURPOSE:To allow the arrangement of deodorant to be easy, permit heat generation of a heater to transmit to a cooler excellently and allow defrosting function to maintain excellently by allowing the device to cover with the deodorant having a specific catalyst on the circumference of a defrosting heater and a further permitting the glass tube circumference surrounding the heater to cover with the deodorant while forming cutouts at a position opposed to the cooler of the deodorant. CONSTITUTION:The circumference of heater wires 20 constituting a defrosting heater 17 is surrounded by deodorant 21. The deodorant 21 mixes a platinum group catalyst such as platinum and iridium in a porous substance to form in the form of a pipe. At first, nasty smell molecules are absorbed by the deodorant 21 excellently. The nasty smell molecules absorbed by the deodorant 21 is burnt and degradated by the heat generation of the heater wires 20 to convert into non-smell molecules such as H2O and CO2 and these are released into a circulation cool current by the operation of a blower 16 at the next cooling time. On the other hand, deodorant 27 is provided so as to cover the circumference of a glass tube 24 and cutouts 28 are longitudinally formed on the upper face opposed to a cooler 5. Thereby, infrared radiation generated from the heater wires 20 penetrates the glass tube 24 to irradiate on the cooler 5 directly upward of the cutouts 28. |
