Through the inner/outer drum structure disclosed by the invention, the heat energy inside the inner drum can be increased during the drying process, the loss of heat energy can be reduced, and the heat exchange area and heat exchange time of hot air inside the inner drum can be increased, so that the drying efficiency of the whole machine is improved.
Description
Technical field
The present invention relates to a kind of washing machine, specifically is the tube structure of washing machine, especially a kind of inner/outer tube structure with drying function washing machine.
Background technology
Be used for the drier of clothes washer-dryer, generating the device that adds hot-air and adopt the mode of heating that adds hot-air by heater.In order to cut down the consumption of energy, developed heat pump clothes dryer successively, use heat pump, strengthen recycle to heat.
No matter be by heater heating drying or heat pump drying, general all be by the air channel with the air of heating by the urceolus rear portion send in the inner core with the wet clothes heat exchange after, with the air of humidity cooling from inner core anterior derive extraneous or after condensation is dried again heating continue drying clothes.
For the inner/outer tube structure of existing roller washing machine,, the gap of 8-12mm is axially arranged, so if load more for a long time in the inner core, hot blast is very low to the efficient that inner core blows because the gap of 15-20mm is radially arranged between inner core and the urceolus.According to the inner/outer tube structure of present roller washing machine, hot blast can directly blow to the urceolus front portion along inner/outer tube gap radially from the gap between inner core rear outside and the urceolus posterior medial, and is sucked out from the outlet of urceolus front upper part.Cause the heat forfeiture, the drying efficiency of clothing reduces, the drying effect variation.
Enter the hot blast the inner core from the inner core rear portion, in blowing to the process that clothing dries, exist two kinds of situations to influence drying efficiency by dissipated heats:
1) the inner core degree of depth is too dark, and hot blast is difficult to blow through clothing, and has scattered and disappeared through the dewatering hole of inner core perisporium;
2) the same from front to back of the dewatering hole on the inner core cylindrical shell cause hot blast to blow to after clothing is obstructed more, and the hole dehydration that sees through inner core cylindrical shell rear portion at the inner core rear portion is scattered and disappeared.If what dewatering hole distributed before and after the inner core is all seldom also not all right, because one be that dehydration rate is not up to standard, the 2nd, the wind path of air draught outward will be obstructed not smooth.
In view of this special proposition the present invention.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, a kind of inner/outer tube structure with washing machine of drying function is provided, in the drying process, increase the heat that enters inner core, reduce scattering and disappearing of heat, increase the area and the heat exchanger time of hot blast heat exchange in inner core, to improve the drying efficiency of complete machine.
For solving the problems of the technologies described above, the present invention adopts the basic design of technical scheme to be: a kind of inner/outer tube structure with drying function washing machine, inner core is with the inside that is located in urceolus, the inner core axle passes the urceolus rear portion, the rear portion of described urceolus is provided with the oven dry air inlet, and the oven dry air inlet periphery between urceolus posterior medial and inner core rear outside is provided with and stops the wind shielding structure of oven dry air intake in inner/outer tube rear portion radial diffusion.
Described wind shielding structure is for being located at urceolus posterior medial and inner core rear outside a plurality of retaining muscle along the circumferential direction respectively, and the retaining muscle is all in the periphery of oven dry air inlet, and retaining muscle radius difference makes the adjacent retaining muscle of urceolus posterior medial and inner core rear outside interlock and overlaps.

Described staggered intersection d is less than the degree of depth of annular groove, and d is 15-20mm.
Described oven dry air inlet by after the setting that turns forward, satisfy: nozzle passed through inner core center and inner core forward flange lower limb successively in the center line of oven dry air inlet extended to.
Described oven dry air inlet is located at urceolus rear portion top, the air intake direction by after slope down to inner core forward flange lower limb forward.
Ratio between the degree of depth L of described inner core and the diameter D satisfies: L/D≤1/2.
Behind the described inner core dewatering hole area sum of 1/3 part be whole inner core dewatering hole the area sum 1/5.
Described wind shielding structure is to be located at the inner core rear outside to enclose the felt of 90 ℃ of high temperature of ability at least along one of circumference, or described felt is located at the position at the corresponding inner core of urceolus posterior medial rear portion.
After adopting technique scheme, the present invention compared with prior art has following beneficial effect.
Inner/outer tube structure of the present invention, between urceolus posterior medial and inner core rear outside, be provided with wind shielding structure, the hot blast at rear portion between the inner/outer tube can be lost in the inner/outer tube gap radially immediately, increase the heat that enters inner core relatively, reduce scattering and disappearing of heat; The present invention makes qualification to the inner core degree of depth and diameter, and the redistribution dewatering hole, has reduced the quantity of rear portion dewatering hole, make that hot blast enters inner core after, slowed down the speed that heat scatters and disappears, improve the efficient of drying clothes; Inclined design for the oven dry air inlet has prolonged the route of hot blast in inner core, has also increased the area and the time of hot blast and clothing heat exchange relatively; Through evidence, above-mentioned improvement of the present invention has improved the drying efficient of 20%-30%.
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
