Description
Technical field
The present invention relates to a kind of tumble-dryer, relate in particular to a kind of power transmission that can bring the tumble-dryer of following effect: the revolving force of motor is passed to the drying roller that is arranged on the body inboard, drying roller is rotated.
Background technology
Generally speaking, tumble-dryer is the machine that the oven dry object (clothes) that washing is over wet is dried automatically.Prior art structure to above-mentioned tumble-dryer describes below.
Fig. 1 demonstrates the profilograph of existing technology tumble-dryer briefly, and Fig. 2 demonstrates the I-line profile of Fig. 1.The tumble-dryer of prior art mainly comprises body 100, drying roller 30, door 105, motor 50, drying roller revolving force transfer device, hot blast guiding stream 10a, 10b, heater 20 and ventilating fan 105.The front of above-mentioned body 100 is formed with input port 100a; Above-mentioned drying roller 30 can be rotatably set in above-mentioned body 100 inside, has been wholely set a plurality of stirring piece 30a on the face around above-mentioned drying roller 30 inboards; Above-mentioned door 40 can open and close above-mentioned input port 100a selectively; Above-mentioned motor 50 is fixed on above-mentioned body 100 inboards, produces driving force; Above-mentioned drying roller revolving force transfer device passes to drying roller 30 with the driving force that above-mentioned motor 50 produces; Above-mentioned hot blast guides stream 10a, and 10b makes extraneous air to above-mentioned drying roller 30 inner inflows, and to above-mentioned body 100 outside discharges, guides flowing of air; Above-mentioned heater 20 is arranged on above-mentioned hot blast guiding stream 10a inboard, and air heat is become the condition of high temperature; Said exhaust fan 105 produces forced air supply pressure, and make extraneous gas pass through above-mentioned hot blast guiding stream 10a and flow into, and to above-mentioned body 100 outside discharges.
Drying work process to prior art tumble-dryer with said structure describes below.
At first, behind above-mentioned drying roller 30 inner input oven dry objects, begin to carry out drying course, then above-mentioned heater (Heater) 20 and motor 50 begin to start.
In addition, startup along with above-mentioned scavenger fan 105, the extraneous air that flow in the above-mentioned body 100 to above-mentioned hot blast guiding stream 10a suction side becomes high-temperature gas formation hot blast through above-mentioned heater 20, is forced in the above-mentioned drying roller 30 by above-mentioned hot blast guiding stream 10a.
