Abstract

The invention discloses domestic drying equipment. The domestic drying equipment comprises a cavity in which a dried object is accommodated and a hot air passage which is used for heating air and conveying the heated air into the cavity; and an air flow mixing device is arranged in the hot air passage. Due to the adoption of the technical scheme, the domestic drying equipment has the advantages that the air flow mixing device is arranged in the hot air passage, air layers or air masses with different temperatures are mixed together, and the temperature of mixed air is uniform, so that adverse effect caused by nonuniform temperature distribution of hot air flow is avoided.

Description

The family expenses drying plant

[technical field]

The present invention relates to a kind of household electrical appliance of drying function, relate in particular to the hot-air channel of this household electrical appliance.

[background technology]

The family expenses drying plant is typically provided with hot-air channel, and heating element heater wherein is housed, and the air after the heating is sent into holding of being attached thereto wait to dry in the cavity of object.

With the dryer is example, and dryer comprises an outer bucket that is loaded in the casing usually, and casing is provided with a clothes inlet, is connected with outer bucket through sealing ring.Rotatably be provided with a cylinder in the outer bucket.A large amount of through holes that distributing on the cylinder, thus spatially communicate with outer bucket.Outer bucket is connected with condensation channel, air-blast device and hot-air channel successively, and the hot-air channel port of export is connected with sealing ring then, thereby forms a circulation of air circulation.Hot-air channel comprises the heater of being located in the passage, the air that heating is passed through.

Because higher near the gas flow temperature of heater usually, lower away from the gas flow temperature of heater, therefore the air-flow of the heater of flowing through can exist temperature difference.In addition, because the out-of-shape of passage itself and heater also can cause channel exit air themperature skewness.The phenomenon of this temperature distributing disproportionation can cause negative effect near some parts such as the sealing ring the channel outlet on the one hand, can reduce sensor result's the degree of accuracy on the other hand, and then have influence on the control to drying procedure.

[summary of the invention]

The objective of the invention is to make the uniform hot-air of hot-air channel ability output temperature of family expenses drying plant.

To above purpose; The technical scheme that the present invention adopts is: a kind of family expenses drying plant; Comprise one and hold by the cavity of oven dry thing, an air that will add after hot-air also will heat is sent into the hot-air channel of said cavity, is provided with an air-flow mixing arrangement in the said hot-air channel.

Adopt the beneficial effect that produces after this technical scheme to be: owing in hot-air channel, be provided with the air-flow mixing arrangement; The gas-bearing formation of different temperatures or air mass are blended in together; More even through mixed air themperature, thus overcome or alleviate the problem that causes owing to temperature is uneven that exists in the prior art.

As further improvement of the present invention, said air-flow mixing arrangement comprises at least one rotatable blade.The blade of rotation can play sufficient stirring action to air-flow, and sphere of action is big, thereby reaches desirable mixed effect, makes gas temperature very even.

Further, said blade is loaded in the rotating shaft that driven by drive unit and rotate.Under the driving of drive unit, blade can be done rotatablely moving of big speed.The blade of rotation can be optimized the air-flow mixed effect more at a high speed, makes gas temperature more even.

Preferably, said air-flow mixing arrangement comprises a plurality of rotatable blades, and said blade has different shapes or setting angle.The blade of difformity or different setting angles can make air-flow in each angle and scope, produce eddy current, thereby makes mixing more thorough.

Said blade alternately in a rotating shaft, the horizontal penetration heat air duct of said rotating shaft.Be provided with like this air that can make in the hot-air channel obtain mixing comparatively fully in the cross section of process.

Preferably, said rotating shaft receives a motor-driven.Under the driving of motor, blade can be done rotatablely moving of big speed.The blade of rotation can be optimized the air-flow mixed effect more at a high speed, makes gas temperature more even.

Preferably, be provided with an air heating apparatus in the said hot-air channel, said air-flow mixing arrangement is located at the downstream of air heating apparatus.

Hereinafter will be described for the example specific embodiments of the invention with the dryer.Except dryer, the present invention also can be applicable to other family expenses drying plant with hot-air channel, for example: dish-washing machine, disinfection cabinet etc.

Fig. 2 is the explosive view of hot-air channel;

Fig. 3 is a hot-air channel.

[specific embodiment]

As shown in Figure 1, dryer 10 comprises one to be located at and to be used to take in fabric to be dried in the

casing

2, and 4, one on the cylinder that under the drive of motor 3, can rotate holds the steel ladle 6 of cylinder 4.Casing 2 is provided with a clothes inlet 8, is connected with steel ladle 6 through sealing ring 12.A large amount of through holes 14 that distributing on the cylinder 4, thus spatially communicate with steel ladle 6.Steel ladle 6 and a condensing unit 16, an air-blast device 18 and a hot-air channel 20 are connected successively; The port of export 22 of hot-air channel 20 is connected on the sealing ring 12; And spatially communicate, thereby form a circulation of air circulation with cylinder 4 and steel ladle 6.

Like Fig. 1 and shown in Figure 2, hot-air channel 20 comprises a conduit wall 24 of being made up of base 21 and loam cake 23, and is located at the air heating apparatus 26 in the conduit wall 24.An air-flow mixing arrangement 28 is located in the conduit wall 24, and is positioned at the downstream of air heating apparatus 26.So the air flow of process air heating apparatus 26 heating is behind air-flow mixing arrangement 28, the air-flow of different temperatures is blended in together, and formation temperature is uniform airflow comparatively, gets into cylinder 4.

Like Fig. 2 and shown in Figure 3, air-flow mixing arrangement 28 comprises the conduit wall 24 of a horizontal penetration heat air duct 20, and the rotating shaft 32 that driven by motor 30.Some vane group 34 are being set in the rotating shaft 32 at interval.Receive the driving of motor 30, vane group 34 is rotated with rotating shaft 32, thereby the air motion around driving plays the effect that mixes, and gas flow temperature is reached unanimity.Each vane group 34 comprises a blade 36 at least.

Preferably, the blade 36 that comprised of air-flow mixing arrangement 28 have make air-flow produce respectively various flows to different shapes or setting angle.These various flows to air-flow merge mutually, make mixing more abundant.

Except embodiment mentioned above, the present invention can also have other the specific embodiment.For example: air-flow mixing arrangement 28 can only comprise a vane group 34, even also can have only a rotatable blade 36; The rotation of blade 36 also can not receive the driving of motor 30, but rotated by the promotion of air-flow.

Preceding text are described and the various specific embodiment shown in the drawings only is used to explain the present invention, are not of the present invention whole.In the category of basic fundamental thought of the present invention, the those of ordinary skill of correlative technology field to any type of change that the present invention carried out all within protection scope of the present invention.
