[0002] With the rapid development of my country's home appliance industry, all-in-one washing and drying machines are becoming more and more popular in the market. At present, the washing machine market is mainly dominated by condensing and heat pump drying methods. Each has its own advantages and disadvantages. The condensing type consumes too much water, and the heat pump type is too expensive. At the same time, too much clothing lint is easily generated during the drying process, which can easily cause the drying system to be blocked after long-term use, affecting the drying function.

[0003] Therefore, it is necessary to improve the existing technology to solve the shortcomings of the existing technology. Summary of the invention:

[0006] The drying tunnel assembly includes a drying tunnel, a blower fan installed on one side of the rear end of the drying tunnel, and a first connecting bellows installed on the front end of the drying tunnel for connecting the drying tunnel and the washing machine tub.

[0013] The present invention has the following beneficial effects: in the washing and drying system of the washing machine integrating drying, condensing and filtering, the drying channel component of the present invention blows dry air from the front of the washing machine, heats the moisture in the wet clothes in the washing machine into saturated water vapor, which enters the condenser at the rear of the washing machine, undergoes a first cooling in the condenser, and undergoes a second cooling in the air inlet cavity of the filter component.

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] The washing machine washing and drying system integrating drying, condensing and filtering of the present invention comprises a drying channel component a, a condensing component b and a filtering component c.

[0024] The drying tunnel assembly includes a drying tunnel 1, a blower fan 2 installed at one side of the rear end of the drying tunnel 1, and a first connecting bellows 3 installed at the front end of the drying tunnel 1 for connecting the drying tunnel 1 with the washing machine barrel. A drying heater 4 is installed on the side wall of the drying tunnel 1 on the same side as the blower fan 2, a temperature sensor 5 is installed on the upper side wall of the drying tunnel 1, and a lower sealing port 12 is formed below the blower fan 2. In the drying tunnel assembly, the blower fan 2 generates drying air volume, sucks low-temperature gas into the drying tunnel 1, and is heated by the drying heater 4 to generate high-temperature gas, which is blown into the washing machine barrel through the first connecting bellows 3, thereby blowing out the water vapor of the clothes in the washing machine barrel and generating saturated water vapor.

[0025] The condensation assembly includes a condenser 6 located at the bottom, the bottom of the condenser 6 is connected to the washing machine barrel, a second connecting bellows 7 is installed above the condenser 6, the condenser 6 is installed together with the filter assembly through the second connecting bellows 7, a condensation water pipe 8 is installed on the filter assembly, and a water inlet valve 9 is installed on the condensation water pipe 8. The high-temperature saturated water vapor generated in the washing machine barrel enters the condenser 6 through the opening at the bottom of the condenser, and at the same time, cold water is sprayed from the condensation water pipe 8 into the condenser 6 through the water inlet valve 9, and the cold water exchanges heat with the high-temperature saturated water vapor, and the water in the high-temperature saturated water vapor precipitates, sinks, and flows back to the bottom of the washing machine barrel and is discharged through the drainage pump. The saturated water vapor and the unsaturated water vapor generated after condensation continue to rise and enter the filter assembly through the second connecting bellows 7.

[0026] The filter assembly includes an upper seal 10 aligned with the lower seal 12 of the drying tunnel assembly, and the upper seal 10 and the lower seal 12 are sealed by a sealing gasket, and the condensation assembly is fastened to the drying tunnel assembly by screws 13. The filter assembly also includes an air inlet cavity 14 and an exhaust cavity 15 located on one side of the upper seal 1 and arranged left and right, and a filter 16 is formed between the air inlet cavity 14 and the exhaust cavity 15, and a filter net is provided in the filter 16. A condensate bellows 17 is installed below the air inlet cavity 14, and the condensate bellows 17 is connected to the condenser 6. The water vapor condensed by the condenser 6 has three states: water vapor still in a saturated state / unsaturated water vapor after condensation / dry air. This part of the low-temperature mixed water vapor after cooling rises together and enters the filter assembly. The dry cold air outside enters the air inlet cavity, and further exchanges heat with the saturated water vapor entering the filter assembly. Condensed water is precipitated from the saturated water vapor, and the condensed water is discharged into the condenser 6 through the condensed water bellows 17, and finally sinks to the bottom of the washing machine barrel and is discharged, further improving the condensation effect. Due to the zoning effect of the filter assembly, an air pressure difference is generated, and the exhaust cavity 15 can quickly discharge part of the low-temperature saturated water vapor at the same time, which also accelerates the drying and condensation effect in disguise. At the same time, the unsaturated low-temperature water vapor, dry air, and the water vapor condensed after the air exchange of the filter assembly are further raised to the drying tunnel assembly through the suction force of the fan 2.

[0027] The invention provides a washing machine washing and drying system integrating drying, condensing and filtering. The drying channel component heats the moisture in the wet clothes in the washing machine into saturated water vapor by blowing dry air from the front of the washing machine, and then the water vapor enters the condenser at the rear of the washing machine.

[0028] The condensation component uses the condenser 6 at the rear of the washing machine to quickly condense through water cooling. At the same time, a set of air exchange filter components is added between the condenser 6 and the drying component. In the air intake cavity 14 of the filter component, the second condensation is completed, and the dry outdoor air entering and the saturated water vapor that has not been completely processed in the first pass are condensed. At the same time, in the exhaust cavity 15, part of the low-temperature saturated water vapor containing high moisture is synchronously discharged into the air outside the washing machine. A filter with a filter net is set in the filter component to collect the cotton wool produced by drying.

[0029] The unsaturated low-temperature water vapor after final cooling and filtration, together with part of the dry air entering from the air inlet mouth 14 of the filter component, is heated again into hot air through the drying tunnel component and blown into the washing machine from the air blowing port at the front of the washing machine. This cycle is repeated to complete the entire drying → water condensation → air exchange condensation → water vapor discharge → filtration → drying process until the moisture in the clothes is completely dried.

[0030] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
