Water condensing device and washing and drying all-in-one machine

Abstract

The invention relates to the technical field of condensing, in particular to a water condensing device and a washing and drying all-in-one machine. Direct heat exchange and indirect heat exchange are integrated so that the condensing effect and the condensing efficiency of the water condensing device can be improved. The water condensing device comprises a condensing chamber and a condensate water channel. A wet and hot air inlet is formed in the lower portion of the condensing chamber, and a dry air outlet is formed in the upper portion of the condensing chamber. The condensate water channel is located inside the condensing chamber, a condensate water inlet communicated with the condensate water channel is formed in the upper end of the condensing chamber, a condensate water outlet is formed in the bottom of the condensing chamber, a spraying structure is arranged on the condensate water channel, and condensate water enters the condensate water channel from the condensate water inlet and enters the condensing chamber through the spraying structure for heat exchange with wet and hot air.

Description

technical field [0001] The invention relates to the technical field of condensation, in particular to a water condensation device and an integrated washing and drying machine. Background technique [0002] A drum-type washer-dryer is a washing machine that integrates washing, dehydration, and drying functions. A drum-type washer-dryer usually includes: a drum, a heating device, a condensing device, and an exhaust device. Among them, see figure 1 , the hot and humid air inlet (not shown) at the bottom of the condensing device communicates with the drum, the dry air outlet 12 at the top of the condensing device communicates with the exhaust device, and the exhaust device communicates with the drum through the heating device. When washing clothes, the high-temperature air heated by the heater enters the drum and exchanges heat with the clothes in the drum under the drive of the exhaust device, so that the moisture in the clothes evaporates, forming hot and humid air that enters...

AI Technical Summary

Problems solved by technology

In the prior art, the form of water condensation is mainly realized by setting a condensed water pipe inside the condensing device, through which the condensed water flows through the condensed water pipe for indirect heat exchange, however, due to the relatively large contact area between the condensed water pipe and the hot and humid air Small, poor condensation effect, low condensation efficiency

[0004] To improve the condensation effect of water condensation, see figure 1 A deflector 5 is arranged at the dry air outlet 12 of the condenser 1, and the deflector 5 and the side wall of the condenser 1 form a groove for blocking the steam that is going to flow out from the dry air outlet 12 , and change the flow direction of the saturated steam to the condensation tank of the condenser 1, forming an airflow vortex, but the vortex increases the airflow resistance, which will reduce the drying efficiency, and, although the structure of the condenser can improve the condensation effect to a certain extent , but did not improve the condensation efficiency
