A gas-fired clothes dryer in the related art includes a casing, a clothes drying drum, a blower fan and a gas-fired heating device, an accommodating space is provided in the casing, and the clothes drying drum, the blower fan and the gas-fired heating device are all disposed in the accommodating space. The gas-fired heating device includes a gas valve, an inlet pipe, a burner, a combustion cylinder and an igniter, the gas valve is provided with an inlet and an outlet, the inlet is connected with the inlet pipe, and the outlet is connected with the burner. The burner is provided with a combustion-supporting air inlet and a spray nozzle, the combustion-supporting air inlet is arranged to enable the combustion-supporting air to enter the burner, and the combustion-supporting air and the fuel gas are mixed in the burner and then sprayed from the spray nozzle. Both the spray nozzle and the igniter are accommodated in the combustion cylinder, and the fuel gas sprayed from the spray nozzle is ignited by the igniter, heat generated by the combustion of the fuel gas heats the air in the combustion cylinder, and under the action of the blower fan, the heated air enters the clothes drying drum to dry the clothes in the clothes drying drum.
The fuel gas used in the gas-fired clothes dryer may be natural gas or liquefied gas, and the amount of combustion-supporting air required when natural gas and liquefied gas are combusted is quite different. When the same volume of natural gas and liquefied gas are combusted, the amount of combustion-supporting air required by liquefied gas is about three times the amount of combustion-supporting air required by natural gas, so the burners adapted to natural gas and liquefied gas are different in structure, and the combustion-supporting air inlet on the burner adapted to liquefied gas is larger than that on the burner adapted to natural gas.
When the gas-fired clothes dryer leaves factory, the burner mounted in the casing is adapted to natural gas, and if the user wants to use liquefied gas, the burner needs to be replaced. For replacing the burner, it is necessary to open the casing and move the clothes drying drum out of the accommodating space before replacing the burner, and the process is cumbersome.
This embodiment provides a gas-fired clothes dryer, where a mounting base is disposed in a housing, a gas-fired heating device is connected to a mounting frame, the mounting frame is detachably connected to the mounting base, and a maintenance port is provided on the housing, and the maintenance port directly faces the mounting base. For replacing a burner, the mounting frame is detached from the mounting base through the maintenance port, and then the gas-fired heating device and the mounting frame are moved out of the housing from the maintenance port to replace the burner on the gas-fired heating device, and the whole process is convenient and fast.
