The board is provided with an air outlet, the air inlet and the air outlet are communicated through a circulating air duct, and a fan is arranged at the air outlet on the circulating air duct; the carbon dioxide heat pump clothes dryer also includes a carbon dioxide heat pump system, and the carbon dioxide heat pump system includes a compressor and is arranged in The evaporator in the circulating air duct and located downstream of the fan and at least one condenser located downstream of the evaporator, the compressor, the evaporator and each condenser are communicated through pipes, the condensers are connected in series, and the pipes are filled with carbon dioxide gas.

The number of the condensers is three and they are arranged at intervals along the gas flow direction in the circulating air duct.

A water collecting plate is arranged under the evaporator in the circulating air duct, and a water collecting pipe corresponding to the water collecting plate is arranged on the pipe wall of the circulating pipe.

A guide plate is arranged below the air inlet in the drying compartment, and a plurality of guide holes are distributed on the guide plate.

The beneficial effects of the utility model: the wet clothes are placed in the drying compartment, the wet air enters the circulating air duct, the wet air passes through the evaporator and at least one condenser in turn, the moisture is condensed into water through the evaporator, and the air is heated through the condenser. The circulating air duct enters the drying compartment again to dry the wet clothes in it. The carbon dioxide heat pump is used to exchange heat with the air through the physical properties of carbon dioxide. As the working medium of the heat pump, carbon dioxide has good adaptability for drying clothes and can achieve better performance. Appropriate air state, compared with the electric heating method in the prior art, it is safer to use. Moreover, the circulating air duct can circulate the air, avoid the humidity pollution and thermal pollution to the external environment, and improve the energy conversion rate.

Description of drawings

FIG. 1 is a schematic structural diagram of an embodiment of a carbon dioxide heat pump clothes dryer of the present invention.

Detailed ways

An embodiment of a carbon dioxide heat pump clothes dryer of the present invention, as shown in FIG. 1 , includes a clothes drying compartment 1, and an air inlet 4 is provided on the upper top plate of the clothes drying compartment 1. In this embodiment, the clothes drying compartment has a door. , the drying compartment is provided with a clothes rail 3 for hanging clothes 2 (wet clothes) to be dried. An air outlet 5 is arranged on the side panel of the lower part of the drying compartment 1 , and the air inlet 4 and the air outlet 5 are communicated through a circulating air duct 6 , and a fan 7 is arranged on the air outlet 5 on the circulating air duct 6 . The carbon dioxide heat pump clothes dryer also includes a carbon dioxide heat pump system. The carbon dioxide heat pump system includes a compressor 16, an evaporator 10 disposed in the circulating air duct and located downstream of the fan 7, and at least one condenser 11 located downstream of the evaporator. This embodiment The number of the middle condensers 11 is three and they are arranged at intervals along the gas flow direction in the circulating air duct. The compressor 16, the evaporator 10 and the condensers 11 are communicated through pipes, the condensers are connected in series, the pipes are filled with carbon dioxide gas, and an expansion valve 12 is arranged between the evaporators and the condensers in the pipes.

A water collecting plate 13 is arranged under the evaporator 10 in the circulating air duct 6 , a water collecting pipe 14 corresponding to the water collecting plate is arranged on the pipe wall of the circulating pipe, and a water collecting device 15 is arranged under the water collecting pipe. The drying compartment is provided with a guide plate 8 below the air inlet, and a plurality of guide holes 9 are distributed on the guide plate to ensure that the hot air can be evenly blown to the inside of the drying compartment from top to bottom, so as to ensure the drying compartment. Wet clothes everywhere in the interior can be blown by hot air, and there are no dead spots. Since clothes of different materials are hung in the drying compartment, various silk threads, cotton threads, duck down and other sundries are present in the internal air. Therefore, an air filter 17 is arranged in the circulating air duct 6 between the fan 7 and the evaporator 10. , to prevent the above debris from clogging the evaporator, just need to clean or replace the air filter regularly.

When in use, the wet clothes are placed in the drying compartment, the wet air enters the circulating air duct, the wet air passes through the evaporator and the three condensers in turn, and the water is condensed into water through the evaporator, and drips onto the water collecting plate. The pipe flows into the water accumulator, the air after passing through the evaporator passes through three condensers to heat the air, and the heated air enters the drying compartment again through the circulating air duct to dry the wet clothes in it, and passes through the deflector. Blow into the dry compartment. The carbon dioxide heat pump is used to exchange heat with the air through the physical properties of carbon dioxide. Research and investigation have shown that carbon dioxide as the working medium of the heat pump has good adaptability for drying clothes and can achieve a more suitable air state. Moreover, compared with the electric heating method in the prior art, not only the conversion rate of energy is improved, but also the use is safer. Moreover, the circulating air duct can make the air circulated, avoiding the humidity pollution and thermal pollution to the external environment.

In other embodiments of the present invention, the number of condensers can be adjusted according to actual needs, which can be one or two, or four or more; the clothes rods in the drying compartment can also be replaced by hangers; A deflector may not be provided in the clothes compartment.
