Abstract

The present invention relates to a washing machine drying condensation method. Said method includes the following steps: heating air by utilizing heating device, making the heated air be fed into washing tub to dry clothes; after the clothes are dried, the saturated wet-hot air can be sucked into the branch tube of Venturi tube, circulating pump can be used for drawing cold water from condensation tank and said cold water can be fed into inlet tube of Venturi tube, the saturated wet-hot air and the cold water are mixed to form air-water mixture, said air-water mixture can be fed into the condensation tank; making the air-water mixture and cold water being in the condensation tank implement full heat exchange in the condensation tank; after heat exchange the discharged saturated wet-cold air can be passed through a back-feeding pipeline and fed into the washing tub interior; the saturated wet-cold air is passed through washing tub and inlet branch tube of drying tube ad fed into the drying tube, after the wet-cold air is heated by heating device, said wet-hot air can be again fed into the washing tube to dry clothes, so that it can make circulating operation.

Description

Drying condensation method of washing machine
Technical field
The present invention relates to a kind of control method of washing machine, specifically relate to a kind of drying condensation method of washing machine, belong to household electrical appliance technical field.
Background technology
Washing machine is now more and more universal, and for adapting to modern's allegro life style, now a lot of washing machines all have the drying condensation system.Fig. 1 is the example schematic of drying condensation method of washing machine of the prior art; Fig. 2 is the fundamental diagram of the drying condensation method of washing machine of prior art.As shown in the figure, existing drying condensation method is in when oven dry, and the saturated damp-heat air 2 after the work enters condenser pipe 13 from washtub 14, contact with cold water 3 in the condenser pipe 13, and temperature reduces, the saturated water capacity reduction of air, water vapor condensation.Condensed saturated cold dry air 4 is by heater 6 heating, and the undersaturated hot-air 1 after will heating is again sent periodic duty in the washtub 14 back to.Carry out condensation owing to need carry out supply cold water 3 by the water feeder 5 in the condenser pipe 13, and owing to be subjected to the restriction of the air water heat transfer type that adopted, cause heat transfer efficiency lower, thereby cause in drying course water consumption excessive, cause the bigger waste of water resource; Under the effect of elevated temperature heat gas, the condensing unit temperature is higher in addition, makes that the efficient of drying system is lower.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of raising thermal efficiency, and can water-saving drying condensation method of washing machine.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of drying condensation method of washing machine is characterized in that comprising the following steps: entering washtub, drying clothes after (1), air are by the heater heating; (2), after the oven dry, saturated damp-heat air is inhaled into from the arm of Venturi tube, simultaneously, circulating pump extracts the inlet tube that cold water enters Venturi tube from condensate tank(trap), saturated damp-heat air and cold water mix the air-water mixture that the back forms and enter condensate tank(trap); (3), in condensate tank(trap), the cold water in air-water mixture and the condensate tank(trap) carries out sufficient heat exchange; The saturated clammy air of (4), discharging after the heat exchange is in feedback pipeline is sent washtub back to; (5), saturated clammy air enters the oven dry pipe through washtub, oven dry pipe entrance branch, send washtub back to after the heater via heating and once more clothing dried, so circulation.
Aforesaid drying condensation method of washing machine, it is characterized in that it comprises that also the condensate tank(trap) water temperature rises after, by suitably replenishing cold water to reduce the step of water temperature from water supplement port.Because the steam content of saturated air is different under the different temperatures, the low more saturated air moisture of temperature is few more, therefore can separate out airborne water effectively.
The invention has the beneficial effects as follows: owing to adopted Venturi tube, condensate tank(trap) and circulating pump, saturated damp-heat air fully mixes with cold water, the heat exchanger effectiveness height, and also water consumption is less.
Description of drawings
Fig. 1 is the example schematic of drying condensation method of washing machine of the prior art;
Fig. 2 is the fundamental diagram of the drying condensation method of washing machine of prior art;
Fig. 3 is the fundamental diagram of drying condensation method of washing machine of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is carried out concrete being described below:
Fig. 3 is the fundamental diagram of drying condensation method of washing machine of the present invention, and as shown in the figure, air is entered washtub 14, drying clothes by heater 6 heating backs from air intake vent.After the oven dry, saturated damp-heat air 2 enters condensation cycle.Condensation cycle is made up of condensate tank(trap) 10, circulating pump 9, Venturi tube 8.Saturated damp-heat air 2 enters circulation by the arm of Venturi tube 8, and simultaneously, circulating pump 9 extracts the inlet tube that cold water enters Venturi tube 9 from condensate tank(trap) 10.Utilize the immixture of Venturi tube 8, saturated damp-heat air 2 is fully mixed with cold water 3, formed air-water mixture 7 enters condensate tank(trap) 10.Circulating pump 9 is as replenishing cold water for mixing constantly for Venturi tube 8.
In condensate tank(trap) 10, after air-water mixture 7 had carried out sufficient heat exchange with cold water, the saturated clammy air 11 that will discharge from condensate tank(trap) 10 was sent back in the washtub again, enters the entrance branch of oven dry pipe again.After heater via 6 heating, the undersaturated hot-air 1 of formation enters once more and carries out drying work in the washtub 14, so circulation.
After water temperature in the condensate tank(trap) 10 rises, suitably replenish cold water to reduce water temperature, to guarantee continuous firing by water supplement port 12 from water feeder 5.Because the rate of heat exchange height, therefore water consumption of the present invention is less; Owing to the steam content of saturated air under the different temperatures is different, the low more saturated air moisture of temperature is few more simultaneously, therefore can separate out airborne water effectively.
The foregoing description does not limit the present invention in any form, and all technical schemes that mode obtained of taking to be equal to replacement or equivalent transformation all drop in protection scope of the present invention.

Claims (2)

1, drying condensation method of washing machine is characterized in that comprising the following steps: entering washtub, drying clothes after (1), air are by the heater heating; (2), after the oven dry, saturated damp-heat air enters the entrance branch of Venturi tube, simultaneously, circulating pump extracts another entrance branch that cold water enters Venturi tube from condensate tank(trap), saturated damp-heat air and cold water mix the air-water mixture that the back forms and enter condensate tank(trap); (3), in condensate tank(trap), the cold water in air-water mixture and the condensate tank(trap) carries out sufficient heat exchange; (4), the saturated clammy air that will discharge from condensate tank(trap) is in feedback pipeline is sent washtub back to; (5), saturated clammy air enters the oven dry pipe through washtub, oven dry pipe entrance branch, send washtub back to after the heater via heating and once more clothing dried, so circulation.
