Detailed Description

Referring to fig. 1 to 3 in combination, according to an embodiment of the present application, a drying assembly includes a condenser 1 for condensing moisture in humid air flowing out through the condenser 1 and sending out dry air;

and a filter 2 for filtering the drain water from the condenser 1.

The condenser 1 condenses moisture in the wet air to achieve the aim of drying; the condenser 1 can adopt heat exchange, contact type and the like, so that the water discharged by the condenser 1 can only comprise condensed water in humid air and can also comprise condensed water and cold source water, and the water discharged by the condenser 1 contains dirt and is clean after being treated by the filter 2, so that the water can be recycled and the aim of saving water is fulfilled.

In some embodiments, the drying assembly further comprises a heat exchange assembly 3, and the discharged water of the condenser 1 is subjected to heat exchange treatment through the heat exchange assembly 3. Because the water discharged by the condenser 1 contains certain heat, the heat exchange assembly 3 is arranged to recover the heat in the discharged water, and the energy can be saved. Preferably, the heat exchange assembly 3 is connected to an outlet of the filter 2 to exchange heat with the filtered drainage.

In some embodiments, the drying assembly further includes a heat storage assembly for storing the condensed water of the condenser 1. The drained water with certain heat can be stored in the heat storage assembly, so that the water can be used next time. Preferably, the heat storage assembly is connected to the outlet of the filter 2, and performs heat storage treatment on the filtered condensed water.

In some embodiments, the filter 2 comprises a lint filter 2.

In some embodiments, the integrated washing and drying machine further comprises a cold water pipeline, the cold water pipeline is connected with the inlet of the condenser 1, and the outlet of the filter 2 is connected with the cold water pipeline.

In some embodiments, the outlet of the filter 2 is connected with the cold water pipeline through the heat exchange assembly 3.

The filtered drainage or the drainage after being filtered and subjected to heat exchange treatment can be returned back to the condenser 1 to be reused as a cold source.

In the embodiment of the application, the washing and drying integrated machine mainly comprises a box body and an internal cylinder body 101, a drying system condenser 102 and a heater 103, wherein the drying system condenser 102 is connected with a rear cylinder through a rubber pipe, and the heater 103 is connected with a front cylinder through a door seal. The air flow circulates in the air duct as follows: driven by the fan system, high-temperature air in the air duct heated by the heater 103 flows through the wet load in the cylinder 101 to be cooled into secondary high-temperature high-humidity air, the secondary high-temperature high-humidity air is connected to the drying system condenser 102 through the rubber connector on the outer cylinder, heat and humidity exchange is carried out again with condensed water entering from the water inlet of the condenser 1, the relative humidity is reduced, and finally the wet load in the circulating air duct is gradually dried through multiple internal circulations to reach the water content required by the system.

During the whole drying cycle, dirt such as lint, thread and even paper scrap can be separated out from the condenser 102 of the drying system, and under the driving of water flow, part of the dirt can be taken away along with the discharge of condensed water. Therefore, under the condition that does not influence drying efficiency, this application carries out cyclic utilization to the water that discharges, carries out filtration treatment to the water that discharges, realizes the purpose of energy make full use of efficiency.

The condensate water cyclic utilization system that this technical scheme set up is located barrel 101 lower part in the box, and the condensed water by condenser 1 exhaust is inserted to the entrance, and the bypass branch road of 1 water inlet of export section access condenser to get into condenser 1 and participate in the circulation heat transfer.

In the initial circulation drying process, cold water is pumped by a water pump to enter a three-way valve 4 and is shunted to a water inlet of a condenser 1. Therefore, after the cold water condenses and dehydrates the hot humid air in the drying air channel, sensible heat and latent heat in the hot humid air are taken away by warming up, the hot humid air is discharged from the condenser 1 and then enters the wire scrap filter 2 for purification and filtration, and then enters the heat exchange unit, the heat of the condensed water is exchanged for the heat exchange tube in the heat exchange unit, the condensed water is changed back to low-temperature water again, the water channel system is adjusted through the valve, and then the appropriate water amount is selected to enter the condenser 1 for heat and humidity exchange circulation.

The temperature of the low-temperature water can be ensured to be equivalent to the temperature of the inlet water of the initial condenser 1 in the initial circulating drying by adjusting the temperature of the inlet water and the flow of the inlet water in the heat exchanger, and a water pipe, a water valve and a water pump which are connected to a user can stop acting, thereby achieving the purpose of saving electricity and water.

In cold winter, the temperature difference between the hot and wet air in the drying air duct and the water temperature at the water inlet of the condenser 1 is large, and the heat transfer and mass transfer efficiency is higher. And in order to prevent the heat exchange system from being frozen and cracked, the system senses the ambient temperature at the moment, if the ambient temperature is less than or equal to 3 ℃, the water in the heat exchange unit is automatically drained, a condensed water circulating system is closed, the heat of the condensed water is not utilized, and the waste water discharged from the condenser 1 is directly discharged out of the box body.

The technical scheme can also be implemented by replacing the following schemes: the slightly high-temperature condensed water from the washing and drying unit is purified by the lint filter 2 and then is stored in a heat-preserving manner without a heat exchange unit, so that half of the washing water can be saved, the waste heat of the condensed water can be fully utilized by using the part of the condensed water in a short time, the purpose of shortening the washing water heating temperature in the cylinder 101 or avoiding heating the washing water is achieved, and water and electricity can be saved.

In summary, the arrangement scheme of the condensed water circulation system of the technical scheme includes, but is not limited to, the above two cases. The new method obtained by simple reasoning and derivation through any one of the methods in the technical scheme is also regarded as the method of the technical scheme.

This application increases a set of thread scraps filter unit outside electric heat washing drying system, or increases a set of heat transfer unit again for retrieve the heat and the water source of comdenstion water. The recovered heat is used for heating cold water entering the cylinder 101 by the washing system, so that the electric heating preheating and temperature rising time is shortened; the recovered condensate water is changed into low-temperature water again after heat exchange and enters the condenser 1 of the drying air channel again to perform the next circulation and perform heat and mass transfer with hot humid air, so that the recycling rate of the condensate water is increased, and the water consumption can be reduced by about 100% in anticipation; meanwhile, the driving power consumption of the water pump and the tee joint is greatly saved, and the energy is further saved.
