- In the following, a washer-dryer according to embodiments of the present invention will be described with reference to
Figs. 1 and 2 . - As shown in
Fig. 1 and Fig. 2 , the washer-dryer according to the embodiments of the present invention includes acabinet 10, an inner drum (not shown), aheat pump 20, afirst heat exchanger 30, asecond heat exchanger 40 and afan 50. Specifically, thecabinet 10 has anair supplement port 11; the inner drum is rotatably disposed in thecabinet 10, defines a containing chamber (not shown) therein, and has an air outlet (not shown) communicating with the containing chamber; theheat pump 20 is disposed to thecabinet 10 and close to theair supplement port 11; thefirst heat exchanger 30 has a first end communicating with a first end of theheat pump 20 and a second end communicating with a first end of thesecond heat exchanger 40, and a second end of thesecond heat exchanger 40 communicates with a second end of theheat pump 20; thefirst heat exchanger 30 and an internal wall face of thecabinet 10 define a condensation channel (not shown) therebetween, thesecond heat exchanger 40 and the internal wall face of thecabinet 10 define a hot air channel (not shown) therebetween, and the condensation channel communicates with the air outlet of the inner drum and the hot air channel; and thefan 50 is disposed in thecabinet 10 to blow hot air in the hot air channel and around theheat pump 20 into the containing chamber. - In other words, the washer-dryer is mainly composed of the
cabinet 10, an outer drum (not shown), the inner drum, theheat pump 20, thefirst heat exchanger 30, thesecond heat exchanger 40 and thefan 50. Thecabinet 10 extends along a vertical direction (an up-down direction shown inFig. 1 ), and the outer drum is fixed in thecabinet 10. The inner drum is rotatably disposed in the outer drum, and an external circumferential wall of the inner drum is spaced apart from an internal circumferential wall of the outer drum. The inner drum defines the containing chamber for containing clothes. The inner drum has an air inlet (not shown) and the air outlet, both of which communicate with the containing chamber. Optionally, axes of the outer drum and the inner drum respectively extend along a front-back direction, that is, the inner drum has an opening towards a front side. - Further, the
heat pump 20, thefirst heat exchanger 30 and thesecond heat exchanger 40 are fixedly disposed in thecabinet 10, the first end and the second end of theheat pump 20 communicate with the first end of thefirst heat exchanger 30 and the second end of thesecond heat exchanger 40 respectively, and the second end of thefirst heat exchanger 30 communicates with the first end of thesecond heat exchanger 40. Therefore, theheat pump 20, thefirst heat exchanger 30 and thesecond heat exchanger 40 form a circulation path for a refrigerant. Thecabinet 10 is provided with theair supplement port 11, and theair supplement port 11 communicates with air around theheat pump 20. Thefirst heat exchanger 30 and thecabinet 10 define the condensation channel therebetween, and the condensation channel communicates with the air outlet of the inner drum. Thesecond heat exchanger 40 and thecabinet 10 define the hot air channel, and the hot air channel communicates with the condensation channel. Therefore, an air circulation path is formed. - The
fan 50 is disposed in thecabinet 10. Optionally, thefan 50 is disposed close to the hot air channel. When the washer-dryer operates a drying procedure, wet air in the inner drum enters the condensation channel, dry air is generated after condensation and then enters the hot air channel, and high-temperature dry air is obtained after being heated by the second heat exchanger. Theheat pump 20 generates a lot of heat during its work, air entering from the air supplement port takes away the heat around theheat pump 20 and enters the hot air channel. High-temperature air in two parts enters thefan 50 under a suction effect of thefan 50, and enters the inner drum to dry the clothes in the inner drum, resulting in a gradually increased humidity of the air, and the air is discharged from the air outlet, and so on. - Accordingly, in the washer-dryer according to the embodiments of the present disclosure, the air entering from the air supplement port can take the heat around the heat pump away by disposing the
air supplement port 11 in thecabinet 10, thus reducing a temperature of the air around theheat pump 20, cooling theheat pump 20 and raising a work efficiency of theheat pump 20. Moreover, the heat around theheat pump 20 can enter the hot air channel to supplement heat for a drying system, to raise a temperature of supplemented air, fully utilize the heat generated by the heat pump during its work, and greatly raise a work efficiency of thesecond heat exchanger 40, so as to further raise a drying efficiency of the washer-dryer. The washer-dryer has a simple and compact structure, a high working efficiency and a high drying efficiency. - According to an embodiment of the present disclosure, the
cabinet 10 has a heatpump mounting chamber 12 used for mounting theheat pump 20, and the heatpump mounting chamber 12 communicates with theair supplement port 11 and the hot air channel. - Specifically, as shown in
Fig. 2 , a side wall of thecabinet 10 and a separating board (not shown) in thecabinet 10 define the heatpump mounting chamber 12 therebetween used for mounting theheat pump 20. The side wall of thecabinet 10 is provided with theair supplement port 11 communicating with the heatpump mounting chamber 12. Theheat pump 20 can generate a great amount of heat during its work, and the air entering from theair supplement port 11 takes the heat around theheat pump 20 away under the suction effect of thefan 50 and then enters the hot air channel to supplement drying hot air needed by the clothes in the inner drum and to cool theheat pump 20 at the same time, which raises the efficiency of theheat pump 20 and effectively utilize the heat around the heat pump 2. - Accordingly, through a flow guidance structure, the washer-dryer makes ambient air pass through a surface of the
heat pump 20 and then enter the hot air channel, thus accomplishing air movement around theheat pump 20 without a cooling fan, enhancing a heat exchange efficiency at the surface of theheat pump 20 and facilitating cooling theheat pump 20. An additional cooling fan is needless, which reduces a part count, simplifies an assembling process, saves a cost and simplifies a control panel. At the same time, the air entering from theair supplement port 11 absorbs the heat from theheat pump 20, thereby raising its temperature. Compared with a conventional heat pump system in which supplemented air has an ambient temperature, the washer-dryer has an air supplement structure which is capable of adding dry supplemented air of a higher temperature to an outer circulation of the heat pump system, thus further facilitating a drying efficiency of a product. - Further, the
fan 50 has theair inlet 51 and theair outlet 52, theair inlet 51 communicates with the hot air channel, and theair outlet 52 communicates with the containing chamber. In other words, the hot air in the hot air channel enters thefan 50 from theair inlet 51 of thefan 50 under the suction effect of thefan 50, and then is exhausted into the inner drum from theair outlet 52 of thefan 50. Accordingly, thefan 50 disposed in thecabinet 10 can drive air to flow and change a direction of airflow. - Specifically, as shown in
Fig. 2 , thefan 50 is disposed below thesecond heat exchanger 40, and theair inlet 51 is located right under thesecond heat exchanger 40. Accordingly, thefan 50 is disposed below thesecond heat exchanger 40, and theair inlet 51 of thefan 50 right corresponds to thesecond heat exchanger 40, thereby reducing a travel path of the hot air, and effectively transporting the hot air in the hot air channel into the inner drum by thefan 50. - Advantageously, the washer-dryer further includes a
filter 60, and thefilter 60 is disposed between the air outlet of the inner drum and thefirst heat exchanger 30 to filter air entering the condensation channel. - That is the washer-dryer is mainly composed of the
cabinet 10, the outer drum, the inner drum, theheat pump 20, thefirst heat exchanger 30, thesecond heat exchanger 40, thefan 50 and thefilter 60. Thefilter 60 is located between the air outlet of the inner drum and the condensation channel, i.e. between the air outlet of the inner drum and the condensation channel in an air intake direction, to filter out and prevent flocks of the clothes from entering the condensation channel and the hot air channel, and to avoid influence on the heat exchange efficiencies of thefirst heat exchanger 30 and thesecond heat exchanger 40. - According to an embodiment of the present disclosure, the
filter 60 has aninlet 61 and anoutlet 62, theinlet 61 communicates with the air outlet of the inner drum, and the outlet communicates with the condensation channel. - Specifically, the
filter 60 has theinlet 61 and theoutlet 62, theinlet 61 communicates with the air outlet of the inner drum, and theoutlet 62 communicates with the condensation channel. Thefilter 60 is further provided with a filtering member therein to filter air before the air enters the condensation channel, so as to filter out the flocks of the clothes. - In addition, according to an embodiment of the present disclosure, the washer-dryer further comprises a
vent pipe 70, and thevent pipe 70 has two ends respectively communicating with theinlet 61 and the air outlet of the inner drum. - In other words, the washer-dryer is mainly composed of the
cabinet 10, the outer drum, the inner drum, theheat pump 20, thefirst heat exchanger 30, thesecond heat exchanger 40, thefan 50, thefilter 60, and thevent pipe 70. As shown inFig. 2 , thevent pipe 70 has a first end communicating with the air outlet of the inner drum and a second end communicating with theinlet 61 of thefilter 60, so as to transmit air. Optionally, thevent pipe 70 may be configured as a thermoplastic pipe which has high reliability and long service life. - Preferably, according to an embodiment of the present disclosure, the heat
pump mounting chamber 12 is close to and spaced apart from the hot air channel. Specifically, as shown inFig. 1 and Fig. 2 , in the embodiment, theheat pump 20, thefirst heat exchanger 30, thesecond heat exchanger 40, thefan 50, thefilter 60, and thevent pipe 70 all are arranged above the inner drum and the outer drum. Optionally, thecabinet 10 has a rectangular section and provided with a horizontally disposed mounting board (not shown) therein, and all of theheat pump 20, thefirst heat exchanger 30, thesecond heat exchanger 40, thefan 50 and thefilter 60 are disposed on the mounting board. - A rear side wall and a right side wall of the
cabinet 10, the mounting board and the separating board define the heatpump mounting chamber 12, and the right side wall and a front side wall of thecabinet 10, the mounting board and the separating board define the condensation channel and the hot air channel which are spaced apart. That is, theheat pump 20 is disposed on the mounting board and located at a right rear position of the mounting board, thefirst heat exchanger 30 and thesecond heat exchanger 40 are disposed on the mounting board and located at a right front position of the mounting board, thefilter 60 is disposed on the mounting board and located at a left front position of the mounting board, at least a portion of thevent pipe 70 is disposed on the mounting board and located at a left rear position of the mounting board, and thefan 50 is disposed under thefirst heat exchanger 30 and thesecond heat exchanger 40. - Accordingly, the washer-dryer is simple and compact in structure, convenient to mount and dismount. Through the flow guidance structure, the washer-dryer makes ambient air enter the heat
pump mounting chamber 12 from theair supplement 11 in thecabinet 10, and makes heat at the surface of and around theheat pump 20 taken into the hot air channel, thus accomplishing air movement around theheat pump 20 without a cooling fan, enhancing the heat exchange efficiency around theheat pump 20 and facilitating cooling theheat pump 20. At the same time, supplemented air having a high temperature enters the hot air channel with no need to be heated by thesecond heat exchanger 40, thus raising the work efficiency of thesecond heat exchanger 40 and raising the drying efficiency of the washer-dryer. - Other configurations and operation of the washer-dryer according to embodiments of the present disclosure are known for those skilled in the art, which will not be described in detail herein.
