Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, dry cleaner of the present invention comprises urceolus 2 and inner core 3, the barrel of inner core 3 has the perforate (not shown) that several pass through for dry-cleaning solvent, need the clothing of washing to be placed in inner core 3 to mix with the dry-cleaning solvent needed for dry-cleaning, inner core 3 is driven by drive unit and rotates, clothing constantly rolls in inner core 3, completes the washing of clothing.The barrel of urceolus 2 has the inlet, leakage fluid dram, air inlet and the exhaust outlet that are communicated with the inner space of urceolus 5.Inlet is positioned at the top of urceolus, and leakage fluid dram is positioned at the bottom of urceolus.Dry cleaner bottom is provided with liquid reserve tank 11, and the seal case stored for dry-cleaning solvent is formed.When dry cleaner starts to wash, the dry-cleaning solvent stored in liquid reserve tank 12 flows in urceolus, for washing clothes.
The outside of dry cleaner urceolus 5 is provided with drying air path 7, and described drying air path 7 two ends connect the air inlet in exhaust outlet on the right side of urceolus 2 and left side respectively.A part for blower fan 8 and heat pump is provided with in described drying air path 7.Described heat pump is made up of end to end compressor, condenser 9 and evaporimeter 10 successively, and it is outside that described compressor is positioned at drying air path 7.Evaporimeter 10 is located in the drying air path 7 of exhaust side, and condenser 9 is located in the drying air path 7 of air inlet side, and it is outside that drying air path 7 is located at by compressor.Described blower fan 8 adopts centrifugal fan, is located in the drying air path 7 between urceolus air inlet and condenser 9.When needing to dry the clothing in inner core 3 and dry-cleaning solvent, start blower fan and heat pump, cold air forms hot-air after condenser 9 heats, enter in urceolus 2 along drying air path 7 through air inlet, dry-cleaning solvent is evaporated under the heat effect of hot-air, dry-cleaning solvent gas after evaporation flows into drying air path 7 with hot-air through exhaust outlet, and is condensed into oil water mixture that is liquid, that be mixed with dry-cleaning solvent and water at evaporimeter 10 place.Described oil water mixture is separated into dry-cleaning solvent and water, and dry-cleaning solvent passes back into liquid reserve tank 11, drains into outside dry-cleaning outside water.
