Air equalizing structure for heat pump module of heat pump type washing-drying integrated machine

Abstract

The invention discloses an air equalizing structure for a heat pump module of a heat pump type washing-drying integrated machine. The air equalizing structure is arranged between the air inlet of the heat pump module and an evaporator and comprises an inlet air channel and a flow equalizing structure in sequence, wherein the air inlet channel is arranged between the air inlet of the heat pump module and the evaporator, the air inlet direction of the air inlet channel gradually changes to a horizontal direction from a vertical direction from the air inlet of the heat pump module at the top to the bottom in an circular arc manner, the flow equalizing structure comprises a plurality of guide plates corresponding to the evaporator, arranged vertically in the horizontal direction of the air inlet channel and used for changing the flowing direction of air, the guide plates incline upwards along the flowing direction of air. The air inlet channel gradually changes into an oval-section air channel from a round-section air channel at the air inlet of the heat pump module, the sectional area is increased gradually, the flowing direction of air gradually changes into a horizontal direction opposite to clearances of fins of the evaporator, and the oval section level is long diameter. By the adoption of the air equalizing structure provided by the invention, the effect of equalizing air passing through the evaporator is improved, splashing of condensate water caused by high-speed air can be avoided, and condensation effect of the evaporator is improved greatly.

Description

technical field [0001] The invention relates to a clothes drying device, in particular to an air equalizing structure for a heat pump module of a heat pump washing and drying machine. Background technique [0002] The following air circulation channel is arranged in the existing heat pump type clothes drying device: the heated air heated by the condenser in the heat pump cycle system is sent into the drying room containing the clothes, and the moist air which has taken moisture from the clothes is It is sent back to the evaporator for dehumidification, and the dehumidified air is heated by the condenser again and sent to the drying chamber. [0003] Chinese Patent Application No. 200610153406.9 discloses a clothes drying device capable of stabilizing the operation of a heat pump generating drying air circulating between the drying chamber and the heat pump. Among them, the air heated by the heater in the heat pump is sent into the water tank as the drying room, and the air ...

AI Technical Summary

Problems solved by technology

[0007] 1. The heat exchange is mainly concentrated at the bottom, and the condensation effect on the hot and humid air is reduced;

[0008] 2. The upper area of ​​the evaporator is not able to absorb heat and condense the air, the utilization rate of the evaporator is insufficient, or the design of the evaporator is wasted;

[0009] 3. The flow rate at the bottom of the evaporator is too high. In the middle of drying, when a large amount of condensed water flows from top to bottom along the fins, splashing will occur. The condensed water splashes into the air and reaches the condenser along the air to absorb the heat of the condenser. Or it is directly brought into the circulating air duct by the air and enters the drum, which reduces the drying efficiency in the middle of drying and affects the entire drying efficiency;

[0010] 4. Condensed water splashes into the condenser to absorb heat, which will reduce the temperature of the air after it is reheated

[0011] The above-mentioned heat pump device has the problem of uneven flow of air passing through the heat absorber and / or heat radiator, and the uneven flow of air leads to uneven drying of hot air, which greatly prolongs the drying time and reduces the drying efficiency
