Condensing laundry dryer
Technical field
The utility model relates to a kind of dryer, particularly a kind of condensing laundry dryer with condensation function.
Background technology
Dryer is a kind of and the supporting equipment of washing machine, be used to dry clean clothing, its structure of existing dryer as shown in Figure 1, mainly by casing 1, cylinder 2, preceding hot-flow flue 3, back hot-flow flue 4, air compartment 5 and be located at fan 6, the motor 7 in the air compartment 5 and the heater 8 be located in the hot-flow flue 4 of back is formed.Wherein, hot-flow flue 3 is communicated with the front and the air compartment 5 of cylinder 2 before described, back hot-flow flue 4 is communicated with the back of cylinders 2 and air compartment 5 and forms circulation canal, the front of cylinder 2 is provided with flange 9, the back is provided with rotating shaft, on the hot blast road junction, the rotating shaft of back was hubbed on the back plate of casing 1 by bearing before the flange 9 of cylinder 2 fronts rode over.Described motor 7 is drive fan 6 and cylinder 2 rotations simultaneously, and the effect that cylinder 2 rotates is to tremble diffusing clothing, and fan 6 has rotated the effect of pump drainage air.The clothes-drying method of this dryer is: air by outdoor through fresh air inlet enter heater 8 be heated as hot-air by after hot-flow flue 4 enter cylinder 2, the clothing in the heated roller 2 makes the water evaporation in the clothing, reaches the purpose of drying clothes.The humid air that has moisture content is discharged outdoor via preceding hot-flow flue 3, air compartment 5 by blast pipe 10 under the driving of fan.This dryer method is called the straight-line clothes-drying method, and this dryer is called the straight-line dryer.Its disadvantage is humid air to be discharged outdoorly with blast pipe, burrows on the wall, connects gas exhaust piping, indoorly will cause room air pollution if come.And existing dryer can not detect the oven dry degree of clothing.

The specific embodiment
Shown in Figure 2 is the structural representation of the utility model condensing laundry dryer.By box body 1, cylinder 2, preceding hot-flow flue 3, back hot-flow flue 4, air compartment 5, be located at fan 6, the motor 7 in the air compartment and heater 8 and the computer control panel be located in the air channel 4, back are formed.Wherein, cylinder 2, forward and backward hot- flow flue 3,4 and air compartment 5 constitute circulation air path; The front of cylinder 2 is provided with flange 9, and the back is provided with rotating shaft 10, and the forward flange 9 of cylinder 2 rides on the hot blast road junction, and the rotating shaft 10 of back is hubbed on the back plate of casing 1 by bearing.Be located at motor 7 drive fan 6 in the air compartment and cylinder 2 rotates, make air via heater 8 heating after, in preceding hot-flow flue 3, back hot-flow flue 4, air compartment 5 and cylinder 2, circulate the clothing heating, drying in the cylinder.For saving heat energy, not discharging outdoor by the hot-air that contains a large amount of steam that comes out in the cylinder, save the installing engineering that burrows on the wall, in air compartment 5, set up condenser 11, the hot-air that will contain a large amount of steam with condenser 11 cools off, and makes the condensate moisture in the hot-air form water, makes damp-heat air become heated dry air, enter the cylinder drying clothes again, recycle.
Referring to the condenser system schematic diagram of Fig. 3 the utility model condensing laundry dryer and in conjunction with Fig. 2, Fig. 4.Described condenser 11 has condensation air channel 111 and cooling air channel 112, hot-flow flue 3 and air compartment 5 before described condensation air channel 111 connects; One end of described cooling air channel 112 is communicated in air intake 13 on the casing by preceding cold air duct 12, the other end of cooling air channel 112 is by back cold air duct 14 fan 15 that runs in, the outlet of ventilating fan 15 is communicated with the exhaust outlet 16 on the casing, exit in condensation air channel 111 is provided with water receiving tank, and this water receiving tank 17 connects ater storage box 18.Enter condenser 11 by the damp-heat air that contains a large amount of steam that comes out in the cylinder through preceding hot-flow flue 3, damp and hot air is condensed into water after running into condenser, simultaneously heat is conducted to condenser, and condensed water flows into ater storage box 18 by water receiving tank 17.The condenser 11 that temperature raises, quilt, is taken away the heat that condenser accumulates via the chilled air cools that preceding cold air duct 12 enters cooling air channel 112 by the air intake from casing 13, makes condenser keep lower operating temperature.Two air channels seal mutually, finish heat exchange by condenser.Condensate moisture in the damp-heat air and make damp-heat air become heated dry air, again by air compartment 5, heater 8 heating, enter the cylinder drying clothes, recycle.The cooling air is discharged by back cold air duct 14, ventilating fan 15 and exhaust outlet 16.
Described condenser 11 is the multiple-layer box type metal condensation devices (as shown in Figure 4) with corrugated plating radiating fin, and described condensation air channel 111 and cooling air channel 112 vertical being arranged alternately.Described condenser is that aluminium or copper are metal, have multilayer metal foil, welding (soldering) corrugated sheet between per two sheet metals, two thin plates and corrugated sheet constitute the air channel, the waveform direction of adjacent two corrugated sheets becomes 90 °, constitutes the air channel that vertically is arranged alternately.
Drive simultaneously by a motor at fan described in the specific embodiment shown in Figure 3 and ventilating fan.Can certainly drive by two motor respectively.
Be to detect the degree that the clothing in the dryer is dried, the used method of the utility model is to be provided with a conducting ring 22 at metal roller 2 outer surfaces as shown in Figure 5, is provided with insulating trip 23 between this conducting ring 22 and the cylinder 2; Fin 20 in cylinder 2 is provided with the conducting strip 21 with the cylinder insulation, and described conducting strip 21 is electrically connected described conducting ring 22; Two conduction brush 24,25 connect metal roller 2 and conducting ring 22 respectively, measure the degree that clothing is dried with the method for measuring the resistance between conducting strip and the cylinder, and this two conduction brush is electrically connected the computer control panel.Described metal roller is a stainless steel drum, and described conducting ring is the stainless steel conducting ring.When clothing and cylinder humidity, resistance is very little, and when clothing was dried the back or do not had clothing, it is infinitely great that resistance is tending towards, and the computer control panel is judged the degree of drying of clothing by the size of detection resistance value.
The course of work of condensing laundry dryer provided by the utility model: air enters via the air inlet on the casing, heater via is heated as hot-air, this hot-air heats the clothing after drying in the cylinder, it is diffusing at the logical cylinder of heating process transfer clothing to be trembled, and is convenient to clothing homogeneous heating water evaporates; For reducing heat-energy losses, exempt and burrowing on the wall, save blast pipe, install and simplify, outside described hot-air is not directly discharged after heats laundry and is, but importing condenser, to contain the hot-air cooling of a large amount of steam, and make condensate moisture in the hot-air become water and hot-air becomes dry air, this dry air is heated as hot-air via heater again, again clothing is carried out drying, recycle.In dry run, measure the degree that clothing is dried with the method for measuring the resistance between conducting strip and the cylinder, the computer control panel will be controlled dryer and quit work when detected aridity reaches setting value.
