Description
Technical field
The present invention is the invention of relevant cloth drying machine parts, specifically relates to the invention of cloth drying machine cylinder seal member.
Background technology
Usually cloth drying machine is to be different from the equipment that washing machine is provided with separately, is used to dry the wet wash after the washing.Press drying mode, cloth drying machine can be divided into condensing and exhaust.
Condensation type cloth drying machine has heat exchanger in inside, allows air in the dryer inner loop, allows humidity condensed Cheng Shui, when water is discharged to the dryer outside, air again with being fed to cylinder inside, drying clothes after the heater heating.
The exhaust cloth drying machine heats, and air conducting is arrived cylinder inside after the dryer air outside is sucked, then to the outside discharge of cylinder.In last number process, the clothing in the cylinder is dried.
Fig. 1 is the structural representation of traditional cloth drying machine.Fig. 2 is in traditional cloth drying machine, the sealing device schematic diagram of cylinder.
As shown in Figure 1, 2, traditional exhaust cloth drying machine (below abbreviate cloth drying machine as) comprises shell 10, door 11, cylinder 12, motor 13, transmission device 14, heater 16, air flow arrangement 15.When shell 10 forms the cloth drying machine outward appearance, be formed with input port 10a in the front.Door 11 opens and closes the input port 10a of above-mentioned shell 10.Cylinder 12 can be rotatably set in above-mentioned shell 10 inside, is used to place clothing, and at the inside circumference face, integrally formed several lifting members (baffle) (figure is slightly).Motor 13 is arranged on the downside of above-mentioned cylinder 12, produces power.Transmission device 14 passes the power of above-mentioned motor 13 to cylinder 12.Heater 16 is arranged on a side of above-mentioned shell 10 inside, and the air that flows into cylinder 12 is heated.Air flow arrangement 15 is behind shell 10 outside suction air, and to heater 16 water conservancy diversion, and an air of heating is to cylinder 12 water conservancy diversion, then the air of the cylinder 12 of flowing through, to shell 10 outside discharges.
Can be rotatably set in the cylinder 12 of shell 10 inside, the one side, the bearing (figure is slightly) that is covered by the back side rotatably supports.Opposite side is rotatably supported by cylinder support portion 16.Cylinder support portion 16 is integrally formed on the above-mentioned positive face shield 10c.
That is, integrally formed in conjunction with flange part 12a in the front of above-mentioned cylinder 12, this has by radial direction in conjunction with flange part 12a and dwindles gradually, presses the outstanding shape of length direction.16 insertions of above-mentioned cylinder support portion are combined in above-mentioned in conjunction with flange part 12a, rotatably the place ahead of back-up roller 12.
In addition, above-mentioned binding site in conjunction with flange part 12a and cylinder support portion 16 is equipped with air packing 17.Air packing 17 prevents that the air of cylinder 12 is to external leakage.Below, be explained.
The peripheral surface of above-mentioned cylinder support portion 16 is recessed to form the air packing mounting groove 16a with certain depth by diametric(al).By air packing mounting groove 16a, annular air packing 17 is installed.At this moment, the inboard of above-mentioned air packing 17 is installed sponge member 18 elastomeric elements such as grade therewith.
In addition, be installed in the air packing 17 of cylinder support portion 16 peripheral surface by above-mentioned air packing mounting groove 16a, its diameter is bigger than above-mentioned internal diameter in conjunction with flange part 12a.But assembling is during cylinder, and above-mentioned sponge member 18 is compressed, and allows the cylinder support portion 16 that comprises air packing 17, insert be combined in above-mentioned in conjunction with flange part 12a.After the assembling of cylinder 12 finished, compressed sponge member 18 can elastic recovery.Above-mentioned air packing 17 is combined closely at the medial surface in conjunction with flange part 12a under the restoring force effect of above-mentioned sponge member 18.Thereby, in drying course, can prevent that the high temperature malaria is to external leakage.
But there are the following problems for the sealing device of above-mentioned cylinder 12.If the restoring force of above-mentioned sponge member 18 is excessive, then air packing 17 and also can become greatly in conjunction with the friction between the flange part 12a hinders the rotation of cylinder 12.And the restoring force of above-mentioned sponge member 18 is when too small, and above-mentioned air packing 17 can not be brought into play sealing function well, and in drying course, the high temperature humid airs in the cylinder 12 might be to external leakage.
Summary of the invention
