Description

Cloth drying device

[technical field]

The present invention relates to a kind of household electrical appliance that are used for drying clothes, relate in particular to the air-blast device in its condenser system.

[background technology]

Existing dryer and collection laundry and clothes drying function are that the cloth drying devices such as clothes washer-dryer of one are typically provided with one and barrel are made up by what machine bucket and the cylinder that rotatably is positioned at the machine bucket were formed, and pending clothing is dried in cylinder.The bucket combination is connected with a condenser system and air heat passage successively.After cloth drying device started drying procedure, dry air was heated to form dry hot-air in the air heat passage, got into bucket combination and wet clothing generation heat exchange then, and the moisture in the clothing is taken away, and formed relatively moister hot-air.Moist hot-air gets into condenser system, and through after the condensation of condenser system, moisture wherein is condensed into water, and the air after being condensed becomes the cold air of relatively dry.The cold air of relatively dry is imported under action of fan in the air heat passage again, gets into next circulation, so goes round and begins again, and finishes until drying procedure.

The patent No. be DE3738031C2 German patent publication a kind of condenser system of utilizing air as cooling medium.Adopt air to comprise at least one oven dry air duct usually, also comprise at least one cooling air channels that communicates with outside air as the condenser system of cooling medium.From the moist relatively thermal air current overbaking dry air passage that the bucket combination is discharged, ambient air stream supercooling air duct, heat exchange takes place in both, makes moist hot-air obtain cooling, so steam wherein condenses into water, from air, separates.

Except the above-mentioned outside air that utilizes, condenser system also can be accomplished cooling and dehumidifying to the oven dry air by the heat dump of heat pump or the water that sprays.

For oven dry gas is circulated again and again, in circulation canal, be provided with the drive unit that drives oven dry gas usually in bucket combination, condenser system and air heat passage.In addition,, a gas actuating device need be set also in the cooling air channels,, carry out heat exchange with the moist hot-air of drying in the air duct so that outside air constantly gets into cooling air channels for the condenser system of utilizing air as cooling medium.

Because in the process of cloth drying device work, need to consume a large amount of energy and time, how improving drying efficiency is the target that breakthrough is sought in this area always.

Fig. 2 is the operation principle sketch map of condenser system among Fig. 1.

[specific embodiment]

As shown in Figure 1, cloth drying device 10 comprises the cylinder 14 that 12, one in a machine bucket can rotate by motor-driven and is loaded in the machine bucket 12.Pending clothing is dried in cylinder 14.Numerous through holes (figure is last not to be shown) are arranged on the wall of cylinder 14, spatially communicate with machine bucket 12 through these through hole cylinders 14.Thereby machine bucket 12 is formed a bucket combination 13 with cylinder 14.Machine bucket 12 is connected with condenser system 16 and heat tunnel 20 successively, forms an air circulation duct 22.One first air-blast device 18 is loaded on the air circulation duct 22, drives the oven dry air and in air circulation duct 22, circulates, and takes away the moisture in the clothing.

Particularly, the workflow of cloth drying device 10 is following: circulating air gets into cylinder 14 after heat tunnel 20 heating, with wherein wet clothing generation heat exchange, the moisture in the clothing is taken away, and forms the air of the high heat of high humidity.The air slave bucket 12 of the high heat of high humidity gets into condenser system 16.Through the condensation of condenser system 16, the moisture in the high hot-air of high humidity is condensed into water, inflow machine bucket 12, and finally discharge through drainage system 24.And the oven dry air after being condensed is imported in the heat tunnel 20 under the effect of first air-blast device 18 again, gets into next circulation.

Condenser system 16 comprises a cooling air intake 34 that communicates with the external world and cooling air outlet slit 36.Second air-blast device 38 sucks condenser systems 16 with outside air from cooling air intake 34, with the oven dry air generation heat exchange through condenser system 16, discharges from cooling air outlet slit 36 after taking away the part heat of oven dry air.

As shown in Figure 2, condenser system 16 comprises by partition wall 8 isolated mutually oven dry air duct 2 and cooling air channels 4.Wherein in the cooling air channels 4 heat exchanging fin 6 is housed.When the oven dry air 3 of circulation flows through temperature is passed to partition wall 8 from oven dry air duct 2, and then pass to heat exchanging fin 6 through partition wall 8.The cool ambient air 5 that gets into cooling air channels 4 is passed from heat exchanging fin 6, is with most of heat, thereby plays the cooling effect to damp and hot oven dry air 3, makes the condensate moisture in the oven dry air 3.

Again comprise an air amplifier 40 with reference to figure 1, the second air-blast device 38.Air amplifier 40 comprises an annular wall 42, annular wall 42 be provided with 44, one Air pressurizers 46 of pressure-air inlet and pressure-air enter the mouth 44 be connected.Air pressurizer 46 sucks air from the external world, and the air after the supercharging is sprayed into annular wall 42 from pressure-air inlet 44, thereby makes the air of high speed high power capacity get into cooling air channels 4 through annular wall 42.Preferably, supercharging device 46 is a turbofan.

The air amplifier is a kind of existing part, has more widely at industrial circle and uses, and its function and principle can be recognized from various existing documents, therefore do not describe in detail at this.Simply say; The air amplifier is to utilize Koln to reach air enlarge-effect-hydromechanical basic principle; Through importing a spot of compressed air as power, the end formation negative pressure of vacuum district in annular wall drives surrounding air and gets into the negative pressure of vacuum district; Combine with the original compression air, formation high speed, jumbo air-flow pass from the annular wall of air amplifier.

Because cool ambient air process from cooling air channels 4 of a large amount of high speeds is arranged, therefore can take away great amount of heat, its heat exchanger effectiveness is higher than the situation of cooling air that only drives with conventional fan significantly, thereby has improved drying efficiency effectively.

In other embodiments, also can in first air-blast device 18, establish the air amplifier, increase the wind speed and the air quantity of the oven dry air of circulation, make interior condensation of unit interval go out more moisture, thereby improve drying efficiency.

In other embodiments; For utilizing water or heat pump to carry out condensation; Perhaps other non-clothing drying devices that utilize cool ambient air to carry out condensation; Also can with air-blast device that circular air channel links to each other in establish the air amplifier, increase flow velocity and the capacity of the oven dry air of circulation through condenser system.

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.
