[0049] Preferably, if Figures 1 to 3 As shown, the drying system of the utility model includes a drying air duct, a heat pump module and a fan 32. The drum module 2 is provided with an air inlet and an air outlet. The two ends of the drying air duct are respectively connected to the air inlet and the air outlet.

Under the action of the fan 32, the airflow can circulate in the drying air duct and the drum module 2, and exchange heat with the evaporator 34 and the condenser 35 when flowing through the evaporator 34 and the condenser 35.

The first drying air duct 31 is connected to the air outlet on the drum module 2, and the second drying air duct 33 is connected to the air inlet on the drum module 2.

[0051] In the present embodiment, the hot and humid air in the drum module 2 circulates under the action of the fan 32, enters the first drying air duct 31, the second drying air duct 33, and the air inlet into the drum module 2 in sequence through the air outlet on the drum module 2, and under the action of the evaporator 34, the moisture in the hot and humid air is condensed and separated from the air flow, and under the action of the condenser 35, the temperature of the air is increased to supply hot air to the drum module 2, thereby drying the clothes in the drum module 2 and further drying the clothes.

[0052] It should be noted that the drying air duct of the utility model is not limited to the two-stage structure described above. Those skilled in the art can also set the drying air duct as a whole-stage structure in actual application. In this case, the fan 32 can be installed on one of the air outlet and the air inlet of the drum module 2, and then the fan 32 is connected to the other air outlet through the drying air duct. Of course, the utility model preferably sets the drying air duct as the first drying air duct 31 and the second drying air duct 33 described above, and the fan 32 is set between the first drying air duct 31 and the second drying air duct 33.

[0053] Preferably, if Figure 1 As shown, the first drying air duct 31 , the fan 32 and the second drying air duct 33 are all arranged above the drum module 2 .

[0054] Preferably, if Figures 1 to 3 As shown, the first drying air duct 31 and the second drying air duct 33 are arranged in an L shape.

[0055] Preferably, the heat pump module of the present invention further includes a compressor (not shown in the figure), which is arranged below the cylinder module 2 .

[0056] Exemplarily, the compressor is vertically arranged at the lower left of the barrel module 2. Of course, the compressor can also be horizontally arranged as long as it can be installed in the lower space between the barrel module 2 and the box body 1. The compressor, evaporator 34 and condenser 35 are connected to each other to form a refrigerant circulation loop. The refrigerant exchanges heat with the hot and humid air flowing through the evaporator 34, which can condense the moisture in the hot and humid air and separate it from the airflow. The refrigerant exchanges heat with the air flowing through the condenser 35, which can increase the temperature of the air, thereby supplying hot air to the barrel module 2.

[0057] Preferably, if Figures 1 to 3 As shown, the first drying air duct 31 includes a return air duct 311 and a first heat exchange air duct 312 which are connected. The return air duct 311 and the first heat exchange air duct 312 are arranged at the upper rear of the barrel module 2, that is, close to the rear end of the barrel module 2. The evaporator 34 is arranged in the first heat exchange air duct 312. The air outlet is arranged at the upper rear of the barrel module 2, that is, the air outlet is also arranged close to the rear end of the barrel module 2, so as to facilitate the return air duct 311 to be connected with the air outlet. The first heat exchange air duct 312 extends in the horizontal direction, and the extension direction of the first heat exchange air duct 312 is perpendicular to the axial direction of the barrel module 2.

[0058] The return air duct 311 and the first heat exchange air duct 312 are preferably configured to be detachably fixedly connected.

[0059] Furthermore, if Figures 1 to 3 As shown, the second drying air duct 33 includes a second heat exchange air duct 331 and an air outlet air duct 332 that are connected. The air outlet air duct 332 and the second heat exchange air duct 331 are arranged at the upper left or upper right of the barrel module 2. The condenser 35 is arranged in the second heat exchange air duct 331. The air inlet is arranged at the upper front of the barrel module 2, that is, the air inlet is arranged close to the front end of the barrel module 2, and the air outlet air duct 332 is connected to the air inlet. The second heat exchange air duct 331 also extends in the horizontal direction, and the extension direction of the second heat exchange air duct 331 is parallel to the axial direction of the barrel module 2, that is, the extension direction of the second heat exchange air duct 331 is perpendicular to the extension direction of the first heat exchange air duct 312, and the two heat exchange air ducts are arranged in an approximately L shape.

[0060] The second heat exchange air duct 331 and the air outlet air duct 332 are preferably configured to be detachably fixedly connected.

[0061] It should be noted that the front end of the drum module 2 has a clothing access port, and those skilled in the art may use the clothing access port as an air inlet, even if the air outlet duct 332 is connected to the clothing access port, or, a separate air port may be opened above the front end of the drum module 2 as an air inlet, and so on. Such adjustments and changes to the specific setting form of the air inlet do not deviate from the principle and scope of the present utility model, and should be limited within the protection scope of the present utility model.

[0062] Preferably, if Figure 2 and Figure 3 As shown, the first drying air duct 31 of the utility model further includes a first connecting air duct 313, a first end of the first connecting air duct 313 is connected to the first heat exchange air duct 312, and a second end of the first connecting air duct 313 is connected to the air suction port of the fan 32. The caliber of the first connecting air duct 313 gradually narrows from the first end of the first connecting air duct 313 to the second end of the first connecting air duct 313, so that the air can be gathered to the air suction port of the fan 32.

[0063] The extension direction of the first connecting air duct 313 is consistent with the extension direction of the first heat exchange air duct 312. It should be noted that the first connecting air duct 313 and the first heat exchange air duct 312 can be fixedly connected, or can also be integrally arranged.

[0064] Preferably, if Figure 2 and Figure 3 As shown, the second drying air duct 33 of the utility model further includes a second connecting air duct 333, a first end of the second connecting air duct 333 is connected to the exhaust port of the fan 32, and a second end of the second connecting air duct 333 is connected to the second heat exchange air duct 331. The caliber of the second connecting air duct 333 gradually widens from the first end of the second connecting air duct 333 to the second end of the second connecting air duct 333, so that the air flowing out of the exhaust port of the fan 32 can diffuse into the second heat exchange air duct 331.

[0065] The extension direction of the second connecting air duct 333 is consistent with the extension direction of the second heat exchange air duct 331. It should be noted that the second connecting air duct 333 and the second heat exchange air duct 331 can be fixedly connected, or can also be integrally arranged.

[0066] Preferably, if Figure 3 and Figure 4 As shown, the first drying air duct 31 of the present invention is provided with a fresh air inlet 3131 , and the fresh air inlet 3131 is located between the evaporator 34 and the fan 32 .

[0067] By setting a fresh air inlet 3131 on the first drying air duct 31, external dry fresh air can be introduced during the drying process, which is beneficial to improving the drying efficiency. In addition, by setting the fresh air inlet 3131 between the evaporator 34 and the fan 32, more fresh air can be introduced, and the temperature of the incoming fresh air will not be affected by the temperature of the evaporator 34, which is more beneficial to improving the drying efficiency.

[0068] For example, Figure 3 and Figure 4 As shown, the fresh air inlet 3131 is arranged on the first connecting air duct 313. Of course, those skilled in the art can also arrange the fresh air inlet 3131 on the first heat exchange air duct 312.

[0069] Preferably, if Figure 3 As shown, a fresh air outlet 3321 is provided on the second drying air duct 33 , and the fresh air outlet 3321 is located downstream of the condenser 35 .

[0070] After washing the clothes, if the user does not take out the clothes in time, the fan 32 can be started without starting the compressor, so that the airflow circulates in the drum module 2 and the drying air duct, and fresh air continuously enters from the fresh air inlet 3131, and part of the airflow will be discharged from the fresh air outlet 3321 to avoid the danger of excessive air pressure in the drum module 2. In addition, by setting the fresh air outlet 3321 downstream of the condenser 35, wind resistance can be reduced and assembly is facilitated.

[0071] Preferably, the washer-dryer of the present invention also includes an exhaust duct (not shown in the figure) and an electric control valve installed on the exhaust duct, one end of the exhaust duct is connected to the fresh air outlet 3321, and the other end of the exhaust duct is connected to the outside of the box 1, and the electric control valve is used to control the on and off state of the exhaust duct.

[0072] By setting an exhaust duct connected to the fresh air outlet 3321, the humid air exhausted from the fresh air outlet 3321 can be directly guided to the outside of the box 1 to avoid excessive humidity inside the box 1. In addition, when there is no need to exhaust air through the fresh air outlet 3321, the electric control valve is in a closed state.

[0073] Preferably, if Figure 4 As shown, a water retaining structure is provided in the drying air duct, and the water retaining structure is used to block the condensed water generated on the evaporator 34 to prevent the condensed water from flowing toward the downstream of the evaporator 34.

[0074] By arranging a water retaining structure in the drying air duct, the water retaining structure can block the condensed water generated on the evaporator 34 and prevent the condensed water from moving toward the downstream of the evaporator 34 .

[0075] It should be noted that those skilled in the art may set the water retaining structure as a water retaining plate or water retaining rib, etc. Such adjustments and changes to the specific structural form of the water retaining structure do not deviate from the principle and scope of the present utility model and should be limited within the protection scope of the present utility model.

[0076] In addition, it should be noted that technical personnel in this field can set the water retaining structure on the inner bottom wall of the drying air duct, or on the inner side wall of the drying air duct, or on both the inner bottom wall and the inner side wall of the drying air duct, etc. Such adjustments and changes to the specific setting position of the water retaining structure do not deviate from the principle and scope of the present utility model, and should be limited within the protection scope of the present utility model.

[0077] Preferably, if Figure 3 and Figure 4 As shown, the water retaining structure includes a first retaining rib 3122 arranged on the inner bottom wall of the drying air duct.

The second retaining rib 3123 is located below the evaporator 34. There are multiple second retaining ribs 3123 and they are spaced apart along the airflow direction.

[0080] Exemplarily, the second blocking rib 3123 is disposed on the inner bottom wall of the first heat exchange air duct 312, and the top of the second blocking rib 3123 abuts against the bottom of the evaporator 34 or extends into the evaporator 34. In addition to blocking condensed water, the second blocking rib 3123 can also block airflow to prevent airflow from passing through the bottom of the evaporator 34, which is conducive to allowing the airflow to pass through the evaporator 34 completely, thereby improving the heat exchange efficiency with the evaporator 34.

[0081] Preferably, if Figure 3 and Figure 4 As shown, the water retaining structure includes a third retaining rib 3124 arranged on the inner wall of the drying air duct. The third retaining rib 3124 is located on the side of the evaporator 34. There are multiple third retaining ribs 3124 and they are spaced apart along the airflow direction.

[0082] Exemplarily, the third blocking rib 3124 is disposed on the inner side wall of the first heat exchange air duct 312, and the side of the third blocking rib 3124 abuts against the side of the evaporator 34 or extends into the evaporator 34. In addition to blocking condensed water, the third blocking rib 3124 can also block airflow to prevent airflow from passing through the side of the evaporator 34, which is conducive to allowing the airflow to pass through the evaporator 34 completely, thereby improving the heat exchange efficiency with the evaporator 34. In addition, the third blocking rib 3124 can also play a role of limiting, assisting the assembly of the evaporator 34.

[0083] Preferably, if Figure 4 As shown, a downwardly recessed water collecting tank 3125 is provided on the inner bottom wall of the drying air duct.

[0084] The water collecting tank 3125 is used to collect condensed water in the drying air duct. A drain outlet 3126 is provided at the bottom of the water collecting tank 3125. The drain outlet 3126 is connected to the condensed water drain pipe 5 for draining the condensed water.

[0085] Exemplarily, the water collecting tank 3125 is located on the inner bottom wall of the first heat exchange air duct 312 of the first drying air duct 31 , is in a long strip shape and extends along the length direction of the first heat exchange air duct 312 .

[0086] Preferably, if Figure 4 As shown, the second retaining rib 3123 extends to the water collecting groove 3125 to guide the condensed water into the water collecting groove 3125.

[0087] That is to say, a diversion channel is formed between two adjacent second retaining ribs 3123 , one end of the diversion channel is connected to the water collecting trough 3125 , and the condensed water flows into the water collecting trough 3125 along the diversion channel.

[0088] Preferably, if Figure 4 As shown, the bottom end of the third retaining rib 3124 extends to the water collecting trough 3125 to guide the condensed water into the water collecting trough 3125 .

[0089] Preferably, if Fig. 9 and Fig.10 As shown, the condensate drain pipe 5 has a water seal pipe section 511 , and the water seal pipe section 511 is located between the water inlet end and the water outlet end of the condensate drain pipe 5 .

[0090] The water seal pipe section 511 is provided between the water inlet and the water outlet of the condensate drain pipe 5, which is conducive to the discharge of condensate. Specifically, the water inlet of the condensate drain pipe 5 is connected with the drain port 3126 on the first drying air duct, that is, connected with the first drying air duct 31, and the water outlet of the condensate drain pipe 5 is connected with the drum module 2. If the water seal pipe section 511 is not provided, the airflow in the drum module 2 will flow along the condensate drain pipe 5 to the first drying air duct 31, hindering the discharge of condensate. By providing the water seal pipe section 511, water is stored in the water seal pipe section 511, which can prevent the airflow in the drum module 2 from flowing to the first drying air duct 31. When the condensate in the condensate drain pipe 5 accumulates to a certain amount, it will slowly flow toward the water outlet of the condensate drain pipe 5 and be discharged smoothly.

[0091] The water seal pipe section 511 is preferably configured as a U-shaped pipe.

[0092] Preferably, if Figures 9 to 12 As shown, the condensate drain pipe 5 includes a first drain pipe 51, a second drain pipe 52 and a third drain pipe 53 which are connected in sequence, the first drain pipe 51 and the second drain pipe 52 are detachably fixedly connected, the second drain pipe 52 and the third drain pipe 53 are detachably fixedly connected, and the water seal pipe section 511 is provided in the first drain pipe 51.
