Water-cooled heat exchanger for washing-drying integral machine

Abstract

The invention relates to a heat exchanger used for a washing-drying integral machine, in particular to a water-cooled heat exchanger for a washing-drying integral machine. The water-cooled heat exchanger comprises a condensed water supply device arranged at the top of the side wall of a condensing air flue of the washing-drying integral machine and a condensed water delay device arranged on the side wall of the condensing air flue, wherein the condensed water delay device comprises a plurality of protrusions which are used for enlarging the contact area of condensed water and damp air; and the protrusions are staggered on the side wall of the condensing air flue under the condensed water supply device. By adopting the technical scheme, the invention provides the water-cooled heat exchanger which can prevent ascending damp airflow producing turbulent flow; meanwhile, the water-cooled heat exchanger can further enlarge the condensing area so as to improve the condensing effect and the integral drying effect of the washing-drying integral machine.

Description

technical field [0001] The invention relates to a heat exchanger for an integrated washing and drying machine, in particular to a water-cooled heat exchanger for an integrated washing and drying machine. Background technique [0002] With the development of technology and the needs of users, the capacity of the washer-dryer is increasing. For the condensing-type washer-dryer, how to improve the efficiency of the heat exchanger in the limited space of the machine has become a technical problem that affects the development of the product. Therefore, people are constantly researching new heat exchangers to obtain better condensation effect and drying efficiency. [0003] At present, most of the integrated washing and drying machines use a water-cooled heat exchanger, that is, the humid air in the washing drum is sucked out by a fan, passed through a condensing heat exchanger to dehumidify, and then the dehumidified air is heated to a certain temperature and blown into the washi...

Problems solved by technology

Although this water-cooled heat exchanger improves the condensation efficiency of the heat exchanger and the drying effect of the washer-dryer to a certain extent, this ribbed structure ignores the fact that the air flow of humid air is lifted from bottom to top in the air duct. In the process of encountering convex ribs to generate scattering turbulence, such as figure 2 As shown in , this affects the circulation of humid air in the condensation air duct to a certain extent, reducing the air volume of humid air, thereby affecting the condensation efficiency of the water-cooled heat exchanger and further affecting the drying of the washer-dryer.
