Abstract: A burner for a gas dryer is made up of a mixing tube having an open end for admission of gas fuel into the mixing tube. At least one other opening proximate to the open end serves to admit air into the mixing tube for mixing the air and the gas fuel. A burner head is located at an end of the mixing tube opposite the open end for allowing a mix of gas fuel and air to be discharged and be ignited into a flame. A baffle is attached to the burner at the base of the burner head and extends radially outward therefrom to prevent disruption of combustion of the gas fuel and air mixture as a result of secondary air being drawn outside and along the length of the mixing tube from the open end thereof toward the burner head. An air heater assembly for gas dryer includes combustion chamber having an air inlet and an air outlet for allowing air to flow therethrough and be heated for being passed over clothes to be dried in a drum of a dryer.

Abstract: A drying rack for the stationary drying of articles to be dried, which can be installed in the drum of a clothes dryer. The articles can be knitwear or shoes that must not be moved when dried even when the drum turns. For articles, especially, wool articles, to dry faster, the drying rack has at least two spaced-apart surfaces disposed one on top of the other on which the articles to be dried can be spread, thereby substantially enlarging the surface of the articles to be dried. As such, the drying air current can better remove the moisture and larger individual wool articles can be dried in the clothes dryer.

Abstract: A heating configuration for a drier, particularly for a laundry drier, has a burner with a burner head, a first heating channel with an inlet opening and an outlet opening, and a second heating channel with an inlet opening and an outlet opening. The cross-sectional area of the second heating channel is greater than the cross-sectional area of the first heating channel. The burner head projects into the inlet opening of the first heating channel and the outlet opening of the first heating channel projects into the inlet opening of the second heating channel. The first heating channel is disposed in the lower section of the second heating channel so that a uniform temperature distribution is achieved in the second heating channel.

Abstract: A drying rack can be fixed in the drum of a tumble dryer to dispose items to be dried in a static manner. The items can be, for example, woolens or shoes that should not be rotated with the moving drum during the drying process. To prevent the items to be dried from coming into contact with the rotating drum, the drying rack includes an external casing, which seals the rack off from the periphery of the drum. An internal rack, in particular, including several levels, can be located inside the external casing. The items to be dried can be distributed on the levels.
