The specific embodiment
Below be detailed description of the present invention,, can be expressly understood the present invention by following description and in conjunction with Figure of description.
One heater to be set, can avoid the long thermal loss that causes of hot blast conveying circuit on the outer bucket top of washing machine like this from the nearest mode in interior bucket upper edge; In the selection of employed heater, can be any of prior art, still, the most suitable is, applicant of the present invention is disclosed mode in CN00215365, comprises the form of heater, the selection of the heating original paper of the position of installation and heater.
But aforementioned as the present invention, the parameter of CN00215365 is not directly chosen in this case, and it does not have the public use parameter yet.
Importantly, the present invention redefines the parameter of this heater and the parameter of the dry run of the parameter of heater and washing machine of the present invention is combined to obtain than the better operating efficiency of prior art.
It is pointed out that two parameters of the heater of selecting for use among the present invention identical: the power of compressor flow and PTC thermistor with CN00215365.
In the present invention, the compressor flow of employing is 2 ~ 3 cubic metres/minute; The power of PTC thermistor is 800--1000 watt.
If adopt other modes, can draw identical or basic similar effects with reference to principle of the present invention.
In the prior art, for example, CN00137763, bucket and/or impeller in the rotation just proposed, but, the purpose of the document is in order to disperse with transpiring moisture and to reduce inhomogeneous drying, obviously do not have centrifugal force of the present invention to drive the notion that air-flow penetrates the clothing that is dried, more not disclosing natural wind of the present invention and hot blast combination drying to reach the notion of optimum drying efficient.
In dry run of the present invention, bucket drying in the rotation is proposed, it is dry to be also referred to as motion, say that definitely interior bucket is with a suitable speed rotation, described speed is minimum can not to be lower than 100 rev/mins, the highlyest surpass 1000 rev/mins, the selection of this velocity interval is based on following two considerations:
The one, the air-flow that can be used in drying just in time penetrates to be dried clothing and can to form certain pressure moist air stream is removed along the interstitial row between outer bucket and the casing, if there are not enough air mass flows from the heater blower fan, the formed circulation of too high rotating speed, 8,9,10 routes referring to Fig. 1, may improve the utilization rate of heat, but the consumption that has also improved electric power simultaneously; Too high rotating speed makes the clothing compactness simultaneously, is not easy to penetrating of hot blast.
The 2nd,, low excessively speed causes clothing to be piled up in a jumble, can not make the clothing that is dried as far as possible in interior bucket side, with abundant contact thermal source as the present invention as shown in Figure 1.
In the present invention, bucket is with certain hour rotating at interval in can making, and the purpose of rotating is suitably loose clothing, improves the effect that penetrates of hot blast.In case of necessity, make the suitable rotating of impeller also can access similar purpose.
As aforementioned, interior bucket rotary course forms centrifugal force makes natural wind or hot blast force to penetrate the clothing that is dried, and the directly circulation of gap, interior bucket of bucket central authorities, inside and outside bucket in forming, because the heater blower fan replenishes air or heated air, a part of humid air in the circulation is discharged by the space of bottom half or other positions along the gap between outer bucket and the casing, thus the drying of finishing.
In case of necessity, can use the support all or part of hang-up of clothing that will be dried, improve air and flow and penetration performance; Support can be shelved on the upper limb of control disc seat or outer bucket, bucket touching the thing that is dried can not be rotated in, even even interior bucket rotate and can not touch under the situation of the thing that is dried, the motion drying of support also is feasible.
In order clearly to distinguish with prior art, the present invention provides the definition of several speech at this, though described speech in this area or other field other definition or implication are arranged, in the present invention, they only are as the criterion with definition of the present invention, and described definition extends to desired claim and summary simultaneously.
Move and dry-refer to, have simultaneously, interior bucket rotation reaches stable or substantially invariable speed, and this is meant, even if speed reaches the speedup of stable or substantially constant front and back and slows down not by therein; Simultaneously necessary again, the dry air of input is heated, and the flow of heated dry air and temperature be stable or substantially invariable, heating beginning and the temperature that finishes increases progressively and the process of successively decreasing is not included in wherein.
Move air-dry-refer to have simultaneously, interior bucket rotation reaches stable or substantially invariable speed, this is meant, even if speed reaches the speedup before and after stable or the substantially constant and slows down not by therein; Simultaneously necessary again, (1) sucks or the dry air of input is not heated, and the flow of heated dry air is not stable or substantially invariable; Or the dry air that (2) suck or import is the substantially constant state that does not reach flow and temperature as yet, and for example, in the described motion oven dry, the temperature of the speedup of interior bucket and deceleration and heating beginning and end increases progressively and the process of successively decreasing all is defined by moving air-dry.
As shown in Figure 2, clothes hanger dry-only refers to, interior bucket is static, the clothing that is dried is supported by clothes hanger or analog, clothes hanger is laid in the upper edge of control disc seat or outer bucket, and simultaneously necessary again, the dry air of input is heated, and the flow of heated dry air and temperature are stable or substantially invariable, and the temperature of heating beginning and end increases progressively and the process of successively decreasing is not included in wherein.
Segmentation further can also comprise:
Static air-dry-only refer to that interior bucket is static (or interior bucket rotation do not reach stabilized (steady-state) speed as yet, for example, the stage of interior bucket speedup or deceleration); Simultaneously necessary again, the dry air of (1) input is not manually heated, and the flow and the temperature of heated dry air are not stable or substantially invariable; Or (2) are not reached the stable or constant of flow and temperature as yet though the dry air beginning of input manually heats.
Clothes hanger is air-dry-only refer to that adopt above-mentioned air-dry mode to carry out drying, and the clothing that is dried is supported by clothes hanger or analog, clothes hanger is laid in the upper edge of control disc seat or outer bucket.
As aforementioned, can also define, if clothing is enough little and guarantee that interior barrel of rotation can not influence under the prerequisite of being hung clothing, the clothes hanger motion is dried and clothes hanger moves air-dry.
Above-described dry air directly comes from the air of the natural environment of washing machine periphery, especially in air drying process, can make the clothing that is dried have the style of air dry, for example, and olfactory.
Circulating air-refer to, part as comprehensive utilization, described dry air can also be recycle, get air scoop from suitable formation of the sidewall of outer bucket, or the upper shed portion of bucket locates outside, forms the air intlet end of heater, the air that will contain waste heat re-enters heater, thereby form circulation, before described air enters heater, can or need not air is dried.
