To provide a warming cabinet for circulating air heated by a heating means and warming an object, especially capable of deodorizing circulated air by a deodorization filter and preventing discharge of odor components again from the deodorization filter even under a high temperature condition.
In a food service cart 1, when a cross flow fan 57 is driven and a warming switch 34 is turned on, by the drive of a flow path switching motor 67, a flow path switching member 63 closes an opening 66 for deodorization. In this case, the air inside a warming chamber 46 does not pass through the deodorization filter 60 and is circulated through an opening 65 for hot air. On the other hand, when the warming switch 34 is turned off, the flow path switching member 63 closes the opening 65 for the hot air. In this case, the air inside the warming chamber 46 is circulated inside the warming chamber 46 by a route passing through the deodorization filter 60 through the opening 66 for the deodorization.
