Description

Be beneficial to dry drum for clothes drier

The utility model relates to a kind of tumbler dryer, especially relates to a kind of structural improvement of drum for clothes drier.

Though existing tumbler dryer is provided with stirring bar, stirring bar direction is set all in axially the paralleling of cylinder, this makes clothes in the process of drying, has only up and down and rolls, and roll before and after not having.Because dryer is subjected to the restriction of structural configuration, heater element is arranged on the front portion of cylinder more, make the clothing that is in the cylinder front portion be heated more, the temperature height, fast drying, the clothing that is in other position then is heated less, temperature is low, dry slow, to such an extent as to it is dried to produce anterior clothing, and bad phenomenon such as the clothing at rear portion is not dried as yet.

For this reason, the someone has applied for the utility model patent of " multipurpose dryer " (application number is 89208919.9) by name.It has the drying tube of rotation, adds hot-air with the PTC heater element, and regulates by air door and to flow through PTC element air capacity and reach the step-less adjustment heating power.And unique oven dry frame is arranged, make it have the dry goods function.But it has increased mechanisms such as accent air quantity, and the distribution of high temperature wind is very unreasonable.

Domestic certain large-scale household appliances group has applied for by name " upward-acting door drying inner core " (number of patent application 97233566.8), and it ties up on 2 sides of annular cylindrical shell and is distributed with fresh air inlet and exhaust vent and 2 turning cylinders.Door that can switch is contained on the anchor ring of annular cylindrical shell.Though it can make the operator need not squat down or bend over to operate, and is easy to operate.But the inner barrel stirring bar direction is set still all in axially the paralleling of cylinder, the distribution of high temperature wind is still very unreasonable.

A kind of centrifugal airing clothes drier (9921758.8).It comprises drive motors, rotating disc, Electric Machine Control structure and supporting structure; Rotating disc is provided with plural hanging structure; Rotating disc is fixedly mounted on the rotor of drive motors, and the Electric Machine Control structure is arranged between drive motors and the power supply, and drive motors and rotating disc support are installed on the supporting structure.Structure is comparatively complicated, and cost is higher.

Goal of the invention of the present utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, need not to increase the dry drum for clothes drier that is beneficial to that facility or cost can obviously improve drying efficient.

Goal of the invention of the present utility model mainly is achieved by following technical proposals: described stirring bar is tilting on the inwall of cylinder, itself and cylinder axially between angle be 10 °-80 °.Usually, described stirring bar and cylinder axially between the optimal value of angle be 15 °-50 °.Like this, stirring bar has produced the roll active force of clothing of front and back simultaneously when rolling clothing up and down, make it clothing and be heated evenly, and directly improved drying efficient.

Goal of the invention of the present utility model can also be able to perfect by following technical proposals: the length of described stirring bar is less than 2/3 of the cylinder axial length, and dislocation before and after the adjacent stirring bar.Described stirring bar can be all parallel to each other, and is also can part parallel to each other, for example the part stirring bar be parallel to cylinder axially, another part then is inclined on the inner wall of rotary drum.

Described stirring bar is the product suitable with inner wall of rotary drum, and is fastened on the cylinder by the mode of mechanical fixation.For example, adopt engineering plastics or other the corresponding prefabricated one-tenth and the suitable part of cylinder of high temperature resistance, adopt the connected mode of various machineries such as screw, riveted joint that it is fastened on the cylinder then.In addition, described stirring bar and cylinder also can be one-body molded.For example, adopt special-purpose formation mould directly on stainless cylinder wall directly punching out become stirring bar.Certainly, the suitable selection of the cross sectional shape of described stirring bar reduces the infringement to clothing to improving drying efficient, and Forming Quality also is an outbalance, and under normal conditions, described stirring bar mean breadth is 1 with the ratio of muscle height: 1-3 is advisable.For the tumbler dryer of two-way stirring class, its stirring bar adopts the isosceles trapezoid shape of symmetry more; And for the cylinder of unidirectional operation, it caters to steep that face can be provided with, and it is more less that the angle in this section, place of another side and barrel then can be provided with.

Therefore, the utlity model has simple in structure, connection and reasonable arrangement, need not to increase mechanical part (arranging uniform utensil etc.) and production cost as agitation means or with hot dry air, what only need change stirring bar is provided with position and shape, it is even to reach drying, and efficient is higher, characteristics such as fast drying.
