The thermally insulating door (1) comprises a housing (101) and a door lining (102). A thermally insulating layer is provided between the housing (101) and the door lining (102). A ventilation pipe (11) is also provided in the thermally insulating door (1). A first through hole is provided on a sidewall of the housing (101). A second through hole is provided on the door lining (102). The ventilation pipe (11) is connected between the first through hole and the second through hole. A valve (3) used for opening or closing the first through hole is provided on the handle (2). By achieving the requirement for balanced air pressure between the interior and exterior of a unit housing while a door is being opened, the door body is convenient for a user to open, thus enhancing user experience.
