Description
Technical field
The present invention relates to a kind of drum for clothes drier, be specifically related to a kind of dryer roller support.
Background technology
Dryer is to be used for drying the equipment that moisture in the washing clothes carries out drying.Usually, dryer is installed in by the washing machine, and the clothing that has dewatered is dried.
Fig. 1 is the cross section view of existing dryer.Comprise: housing 10, be arranged on cylinder 30 in the housing 10 with rotation mode, drive motor 20, it is installed in the housing 10 and produces driving force, so that swing roller 30; Belt 40 and belt pulley 41 are used for drive motor 20 and cylinder 30 are coupled together, and the revolving force of drive motor 20 are passed to cylinder 30; Back plate 50, it is arranged to circular slab, is used to cover the rear side of cylinder 30, and has the inlet scoop 51 that is made of a plurality of through holes; And header board 60, it is arranged to circular slab, is used to cover the front side of cylinder 30, and has inlet 61 and exhaust outlet 62.
In addition, dryer also comprises: air-suction duct 70, and it links to each other with inlet scoop 51, as the passage that air is sucked cylinder 30 from the outside; Heater (H), the intake section that it is installed to air-suction duct 70 is used to heat institute's inhaled air; Exhaust duct 80, it links to each other with the exhaust outlet 62 of header board 60, as being emitted on the passage of finishing the humid air behind the drying course in the cylinder; And fan 91, it is installed in the exhaust outlet 80, and relies on drive motor 20 to produce air blast; On the bonnet of housing 10, be provided with a plurality of air vents 11.
The door (D) that is used to out/closes dryer is installed to the front surface of housing 10, and the filter (F) that is used to filter such as impurity such as fine hair is installed in the exhaust duct 80.
In cylinder 30, be provided with a plurality of baffle plates 32, so that increase and the contact area that adds hot-air with cylinder 30 rotations.
The fixture of relevant cylinder has dual mode:
Wherein as shown in Figure 1 a kind of, in Fig. 1, described cylinder 30 is rotatably to be supported in the housing 10 by four (each two of front and back) backing roll R, and drive motor 20 is by belt transmission, and head roll 30 rotates on backing roll R.The advantage of this structure is simple, but exists in the roller rotating process swing bigger, and particularly, when wherein a certain supporting roller bearing frictional force is bigger, it is bad to roll, and the beat of creeping between cylinder and the backing roll can take place.
Another kind of fixed form is, cylinder still adopts backing roll R near door (D) end, perhaps adopts the friction plate of nozzle underlay high-abrasive material, and the cylinder bottom center then is provided with central shaft (as shown in Figure 2), and on housing 10, advantage is that swing is little by bearing fixing.But this position belongs to high-temperature area in the dryer course of work, and the bearing heat radiation in this fixed structure is bad.
A kind of bearing support assembly is disclosed in application number 200480038613.9 titles are the application for a patent for invention of dryer; this invents used bearing is oiliness bearing; because the hot blast of drying enters cylinder from the cylinder bottom that is provided with bearing; therefore bearing is worked under hot conditions; the problem of bringing is that oil is volatilized rapidly and does and consolidates; in order to protect the bearing can be not overheated, be provided with a cooling device that is used for cooling bearing.Specifically as shown in Figure 3, between carriage 10 that bearing is set and air-distribution cover 18 annular gap 33 is set, cold surrounding air, cools off bearing bearing 9 other skimming over by annular gap 33.Annular gap 33 is to form by the isolation projection 34 that is configured on the air-distribution cover 18.The bearing of this invention is fixed in by carriage 10 on the rear wall 11 of casing 1, and so there is very burden in structure when assembling, is installed on the drum shaft if the carriage 10 of bearing will be housed earlier, and then the centering fixing and bearing of carriage and rear wall 11 is all compared difficulty; If earlier with the fixing of carriage and rear wall 11, and then the carriage 10 that will have a rear wall 11 is installed on the roller bearings, and its centering has problems equally, and it is also very inconvenient to install.
Summary of the invention
