Abstract

The utility model discloses a dryer which comprises a tumbler arranged in the case body of the dryer and driven by an electromotor to rotate along a rear shaft, a plastic tumbler bearing is fixed on a back plate behind the tumbler, one end of the plastic tumbler bearing, which serves as a shaft cover, is matched with the rear shaft, the other end is movably matched with a filtering net cover, the combined end of the plastic tumbler bearing and the filtering net cover is a cylinder, and a latch notch is formed on the filtering net cover corresponding to the cylinder. The utility model effectively reduces the abrasion between the latch notch and the plastic tumbler bearing, enables the combination between the latch notch and the plastic tumbler bearing to be firm, causes the disassembly to be very convenient, prolongs the service life of the latch notch and the plastic tumbler bearing, and improves the stability of the filtering net cover.

Description

A kind of dryer

Technical field

The utility model relates to a kind of dryer, relates in particular to a kind of drum-type tumble drier.

Background technology

When climate is relatively moist, cold weather and sunshine is when strong, clothing almost not have the possibility that becomes dry, and generally people use dryer that clothes is dried, and most people are to use tumble drier to carry out drying.

In general, tumble drier be high temperature air by drying in the drying drum inner loop, the household electrical appliance that the wet washings of putting into drying drum inside is dried.Air flow into and is heated by heater after the dryer inside, and Jia Re air flow into cylinder inside then, the washings of cylinder inside is carried out drying after, be discharged to the outside.In dryer, the room air of inflow by heater and cylinder after, in the time of again by filtering screen, tomentums such as fine, soft fur filter out.Afterwards, the air of the cotton filtering screen of process is discharged to indoor by the exhaust bucket of dryer lower end again.In addition, under the situation of dryer work, room air flow into drying drum inside by suction inlet, and the air that flow into drying drum inside carries out the washings of cylinder inside being discharged to indoor again after the drying.Therefore but in the dryer of prior art, room air is to be fed directly to cylinder inside, need prevent that fine hair such as dust, fine, soft fur from flowing into cylinder inside, promptly needs to prevent by the fine hair that air suction inlet the sucks washings of cylinder inside of making dirty.The filtering screen and the roller bearings of existing dryer exist bigger wearing and tearing on cooperatively interacting, make the stability reduction of secure fit between the two, have shortened the service life of filtering screen and roller bearings.

The utility model content

The utility model is in order to overcome the deficiencies in the prior art, a kind of tumbler dryer that improves present product deficiency to be provided.

A kind of dryer disclosed in the utility model, be included in to be provided with in the dryer casing and reach the cylinder that rotates around rear axle by motor-driven, the cylinder postnotum is fixed with the cylinder plastic bearing, cylinder plastic bearing one end is matched with rear axle as axle sleeve, other end activity is combined with filtering screen, the abutting end of described cylinder plastic bearing and filtering screen is the annulus post, and filtering screen corresponding circle annulated column is provided with bayonet socket.

In order to make bayonet socket and cylinder plastic bearing good fit better, firm, the utility model is designed to further: the bayonet socket inner surface is provided with little protruding position or outer surface is provided with annular groove, and the annulus outer surface of column of cylinder plastic bearing is provided with the annular groove that cooperates with the little protruding position of bayonet socket inner surface, or annulus post inner surface is provided with the little protruding position that cooperates with bayonet socket outer surface annular groove; Certainly, the utility model also can be designed as the bayonet socket inner surface and is provided with annular groove or outer surface and is provided with little protruding position, the annulus outer surface of column of cylinder plastic bearing is provided with the little protruding position that cooperates with bayonet socket inner surface annular groove, or annulus post inner surface is provided with the annular groove that cooperates with the little protruding position of bayonet socket outer surface.

In addition, for the ease of cylinder plastic bearing and bayonet socket more can be good loading and unloading, the cleaning and filtering guard be a matched in clearance between little protruding position and the annular groove, and the shaped design of little protruding and annular groove cross section is a semiellipse or trapezoidal.

The filtering screen of the tumble drier that the utility model is designed cooperatively interacts by bayonet socket on the guard and cylinder plastic bearing annulus post, can reduce the wearing and tearing between bayonet socket and the cylinder plastic bearing effectively, bayonet socket is cooperated firmly with the cylinder plastic bearing, load and unload also very convenient, prolong the service life of bayonet socket and cylinder plastic bearing, improve the stability of filtering screen.

The specific embodiment

Below will be described in detail preferred embodiment of the present utility model.

Among the utility model embodiment 1, as shown in Figure 1 and Figure 2, be included in to be provided with in the dryer casing 1 and reach the cylinder 2 that rotates around rear axle 3 by motor-driven, cylinder 2 postnotums are fixed with cylinder plastic bearing 6, cylinder plastic bearing 6 one ends are matched with rear axle 3 as axle sleeve, other end activity is matched with filtering screen 4, and cylinder plastic bearing 6 and abutting end filtering screen 4 are annulus post 10, and filtering screen 4 corresponding circle annulated columns 10 are provided with bayonet socket 5; Bayonet socket 5 inner surfaces are provided with little protruding position 7, and cylinder plastic bearing 6 annulus posts 10 outer surfaces are provided with and the little protruding position of bayonet socket 5 inner surfaces 7 annular grooves that cooperate 8; The cross section radius of bayonet socket 5 is greater than the cross section radius of annulus post 10, and annular groove 8 is semiellipse with the shape of cross section of little protruding position 7, and the cross section radius of annular groove 8 is greater than the cross section radius of little protruding position 7.

In the present embodiment 2, as shown in Figure 3, on the basis of embodiment 1, keep the dryer casing, cylinder, under the constant situation of rear axle, the bayonet socket 5 of filtering screen 4 and the annulus post 10 of cylinder plastic bearing 6 are improved design, then the outer surface at bayonet socket 5 is provided with annular groove 8, annulus post 10 is provided with corresponding bayonet socket 5 outer surface annular grooves 8, the little protruding position 7 that is mated, annulus post 10 cross section radiuses are greater than the cross section radius of bayonet socket 5, annular groove 8 is semiellipse with the shape of cross section of little protruding position 7, and the cross section radius of annular groove 8 is less than the cross section radius cylinder of little protruding position 7.

When the dryer operate as normal, good fit by filtering screen and cylinder plastic bearing can play the good filter effect of dryer.

The above only is preferred embodiment of the present utility model, is not the utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
