For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0047] In the related technical field of clothes drying machines, the heat pump system functions as heating and condensing. The hot air generated by the condenser driven by the fan impeller flows to the bottom of the drum through the volute to convert the moisture in the clothes into water vapor, and then flows to the evaporator to reduce the temperature of the water vapor to convert it into condensed water. At this time, the airflow is dried and then flows to the condenser to be heated and sent back to the drum to complete the drying. This drying method causes the wind at the bottom of the drum to blow the clothes to the drum opening close to the door body when there are fewer clothes, and the clothes need to be shaken several times to the center of the drum for drying. When the clothes drying machine is fully loaded, the clothes accumulate in the center of the drum and are tangled, which cannot be stretched out. Therefore, in the case of fewer or full loads of clothes in the drum, there is a problem of low drying efficiency.

[0048] Based on this, the following embodiments are proposed.

[0049] Embodiment one:

[0050] As shown in Figures 1-3 , the present embodiment provides a clothes drying machine, which is provided with a drum 1, and the drum 1 is provided with an air inlet 101 and an air outlet 102; the clothes drying machine comprises:

[0051] a drying air duct, which is connected between the air inlet 101 and the air outlet 102 of the drum 1, and at least part of the drying air duct extends axially along the drum 1 and is located below the drum 1;

[0052] The air inlet 101 is arranged at the front of the drum 1, and the air outlet 102 is arranged at the rear of the drum 1;

[0053] When the clothes drying machine is drying, the drying air flows in the drum 1 from the front to the rear.

[0054] In the present embodiment, the drum 1 is arranged in the box body of the clothes drying machine and can rotate with the drum motor. The drying air duct serves as a channel for the circulation of hot air in the clothes drying machine. By designing the drying air duct to extend axially along the drum 1 and be located below the drum 1, in combination with the air inlet 101 arranged at the front of the drum 1 and the air outlet 102 arranged at the rear of the drum 1, the user can select a corresponding program for drying according to the material of the clothes. When the clothes drying machine is working, the hot air generated by the heat pump system 13 is delivered into the drum 1 through the air inlet 101 at the front of the drum 1 by the drying fan 2 to dry the clothes in the drum 1. The high-temperature hot airflow converts the moisture in the clothes in the drum 1 into water vapor, which is discharged through the air outlet 102 at the rear of the drum 1. Then, the heat pump system 13 converts the water vapor into condensed water. The air without condensed water is heated by the heat pump system 13 and enters the drum 1 through the air inlet 101. The hot airflow is repeatedly circulated in the drying air duct to the clothes in the drum 1 until the moisture in the clothes is completely converted into condensed water to complete the drying.

[0055] When the user puts in less clothes in the drum 1, the clothes are blown by the air at the air inlet 101 located at the front of the drum 1 to the center of the drum and gradually stretched to the straight state by the spray of water vapor opened by the care module, so that the clothes are de-wrinkled. Compared with the clothes state after being dried by the air outlet at the bottom of the drum, the clothes are more stretched, and the air blown into the drum 1 by the air inlet 101 located at the front of the drum 1 is divergent and will not be concentrated in a certain place. When the clothes are more and shaken by the rotation of the drum 1, the clothes can be uniformly heated to accelerate the evaporation of water, thereby improving the drying efficiency.

[0056] Compared with the traditional clothes dryer, the clothes dryer in the embodiment blows hot air into the drum 1 through the air inlet 101 located at the front of the drum 1, which belongs to blowing from the front to the rear of the drum 1 of the clothes dryer. The problem of the traditional clothes dryer that the air outlet at the bottom of the drum is solved, which causes the drying time to be prolonged when the clothes are less and the clothes are blown to the drum port by the air, and the problem of the traditional clothes dryer that the air volume and temperature of the air inlet at the bottom of the drum are not uniformly distributed in the drum is solved, and the evaporation of water in the clothes is slower.

[0057] Compared with the traditional air inlet at the bottom of the drum, the hot air blown from the front to the rear of the drum 1 can prevent the clothes load from being blown to the lower side of the glass bowl, so that the clothes are uniformly stretched. When the clothes are cared, the water, negative ions, ozone and the like can be cared and de-bacterized along the air direction, so as to improve the efficiency and effect of care and de-bacterization. The front air inlet can uniformly bring the hot air to the surface of the clothes when the clothes rotate with the drum 1, thereby improving the drying efficiency and shortening the drying time.

[0058] Optionally, in one implementation manner of the embodiment, as shown in Figure 1 , the clothes dryer further comprises a care module 4 located at the front of the drum 1.

[0059] The drum is provided with a drum port 10, and the air inlet 101 is annularly arranged around the drum port 10.

[0060] In the embodiment, the air inlet 101 is annularly arranged around the drum port 10, the air blown into the drum 1 from the air inlet 101 is more comprehensive and uniform, and the air inlet is more divergent and will not be concentrated in a certain place. When the clothes in the drum 1 are less, the clothes are more stretched during the process of being blown by the air at the air inlet 101 located at the front of the drum 1 to the center of the drum, and the drying efficiency is higher. When the clothes are more and shaken by the rotation of the drum 1, the clothes can be uniformly heated to accelerate the evaporation of water, thereby improving the drying efficiency.

[0061] Optionally, in one implementation manner of the embodiment, as shown in Figure 1 , the clothes dryer further comprises a care module 4 located at the front of the drum 1.

[0062] The clothes dryer further comprises a drying fan 2 located on the drying air duct and a heat exchange module 3.

[0063] The drying fan 2 is arranged close to the air inlet 101 and downstream of the heat exchange module 3 on the drying air duct.

[0064] In this embodiment, when the clothes dryer is in operation, the hot air heated by the heat exchange module 3 is delivered into the drum 1 by the drying air blower 2 through the air inlet 101 located at the front of the drum 1 to dry the clothes in the drum 1. The high-temperature hot air flow converts the moisture in the clothes in the drum 1 into water vapor, which is discharged through the air outlet 102 located at the rear of the drum 1. Then, the heat exchange module 3 converts the water vapor into condensed water. The air without condensed water is heated by the heat pump system 13 and enters the drum 1 through the air inlet 101. The hot air flow is repeatedly circulated in the drying air duct to the clothes in the drum 1 until the moisture in the clothes is completely converted into condensed water, and the drying is completed.

[0065] The drying air blower 2 is arranged close to the air inlet 101 and downstream of the heat exchange module 3 in the drying air duct, so that the drying air blower 2 forms a front air inlet structure. Under the same power condition, the front air inlet structure has a shorter air inlet stroke and higher air inlet efficiency. During the drying process, the clothes are evenly brought to the surface of the clothes when the drum rotates, which improves the drying efficiency and shortens the drying time.

[0066] Optionally, in an implementation manner of the embodiment, as shown in Figures 1-3 , 5-7,

[0067] The drying air duct includes a front air duct 4, a bottom air duct 5, and a rear air duct 6.

[0068] The clothes dryer includes a base 7 and a front support 8. Wherein,

[0069] The base 7 is located below the drum 1.

[0070] The front support 8 is vertically arranged at the front end of the base 7 to support the drum 1 rotating relative to the front support 8. The rear air duct 6 is vertically arranged at the rear end of the base 7.

[0071] The front air duct 4 is formed in the front support 8, and the bottom air duct 5 is formed in the base 7.

[0072] One end of the front air duct 4 is communicated with the air inlet 101 upward, and the other end is communicated with one end of the bottom air duct 5 downward. The other end of the bottom air duct 5 is communicated with the rear air duct 6. The other end of the rear air duct 6 is communicated with the air outlet 102.

[0073] The drying air blower 2 is arranged on the front support 8 to guide the drying air of the bottom air duct 5 into the front air duct 4.

[0074] In this embodiment, the base 7 is arranged below the drum 1, and the heat pump system 13 and the drum motor are arranged in the base 7. The front support 8 is arranged on the base 7 to support the drum 1 to rotate. The front air duct 4 is arranged on the front support 8 and communicates with the drum opening 10 of the drum 1 and the drying fan 2 to convey hot air to the drum 1. The rear air duct 6 is arranged outside the cabinet of the dryer and communicates with the drum bottom of the drum 1 to return the air dried by the drum 1. The heat pump system 13 is arranged in the base 7 and communicates with the drying fan 2 and the rear air duct 6. The front support 8 is vertically arranged at the front end of the base 7 to support the drum 1 to rotate relative to the front support 8. The rear air duct 6 is vertically arranged at the rear end of the base 7. The front air duct 4 is formed in the front support 8. The bottom air duct 5 is formed in the base 7. The front air duct 4, the bottom air duct 5, and the rear air duct 6 are arranged around the drum 1. This arrangement facilitates the air intake of the drum 1 and reduces the space occupied by the air duct in the cabinet of the dryer, thereby saving the space in the cabinet of the dryer and making the internal structure of the dryer compact.

[0075] One end of the front air duct 4 communicates with the air inlet 101 upward, and the other end communicates with one end of the bottom air duct 5 downward. The other end of the bottom air duct 5 communicates with the rear air duct 6. The other end of the rear air duct 6 communicates with the air outlet 102. The drying fan 2 is arranged on the front support 8 to guide the drying air of the bottom air duct 5 into the front air duct 4. The hot air heated by the heat exchange module 3 is conveyed into the drum 1 through the air inlet 101 at the front of the drum 1 by the drying fan 2 to dry the clothes in the drum 1. The high-temperature hot air flow converts the water in the clothes in the drum 1 into water vapor. The water vapor is discharged through the air outlet 102 at the rear of the drum 1. Then, the heat exchange module 3 converts the water vapor into condensed water. The air without condensed water is heated by the heat pump system 13 and enters the drum 1 through the air inlet 101. The hot air flow is repeatedly circulated in the drying air duct to the clothes in the drum 1 until the water in the clothes is completely converted into condensed water to complete the drying. Compared with the traditional drum bottom air intake, the hot air blown from the front to the rear of the drum 1 can prevent the clothes load from being blown to the lower side of the glass bowl, so that the clothes are evenly stretched. When the clothes are treated, the water, negative ions, and ozone can be treated and degermed along the air direction, thereby improving the efficiency and effect of the treatment and degerming. The front air intake can uniformly bring the hot air to the surface of the clothes when the clothes rotate with the drum 1, thereby improving the drying efficiency and shortening the drying time.

[0076] Optionally, in an implementation manner of the embodiment, as shown in Figures 1-3

[0077] The dryer is provided with the heat pump system 13. The heat pump system 13 includes the heat exchange module 3. The heat exchange module includes the condenser 301 and the evaporator 302. The condenser 301 is close to the front air duct 4. The evaporator 302 is close to the rear air duct 6. The drying fan 2 is arranged on the front air duct 4, and the air inlet direction of the drying fan 2 is toward the condenser 301.

[0078] ​In the embodiment, the heat pump system 13 is composed of a compressor, a condenser 301, an evaporator 302, etc.; the drying fan 2 is arranged on the front support 8, and the drying fan 2 includes a volute 201, an impeller 202, a fan upper cover, etc. Compared with the traditional clothes dryer, in the embodiment, the condenser 301 is close to the front part of the clothes dryer, i.e. the front support 8, and the evaporator 302 is close to the rear air duct 6, i.e. the wet air return channel. The drying fan drives the hot air generated by the condenser 301 to be transported into the drum 1. The condenser 301 is close to the drying fan 2, and the working of the condenser increases the temperature of the air around the condenser. The air with a higher temperature is driven by the drying fan 2 to be transported into the drum 1 to convert the moisture in the clothes into water vapor. The evaporator 302 is close to the rear air duct 6, and the evaporator generates a lower temperature to convert the water vapor in the rear air duct 6 into condensed water. Compared with the traditional clothes dryer, the hot air is blown into the drum 1 from the air inlet 101 located at the front part of the drum 1, which belongs to blowing from the front part of the drum 1 of the clothes dryer to the rear part. The problem that the drying time is prolonged due to the clothes being blown to the drum port by the air when the clothes are less in the traditional clothes dryer is solved. In addition, the problem that the air volume and temperature of the air entering from the bottom of the drum are not uniformly distributed in the drum, and the moisture in the clothes evaporates slowly is solved.

[0079] Optionally, in an implementation manner of the embodiment,

[0080] The base 7 is formed with a first cavity and a second cavity;

[0081] The first cavity forms the bottom air duct 5, and the condenser 301 and the evaporator 302 are located in the first cavity;

[0082] The second cavity forms a cavity for accommodating the compressor of the heat pump system;

[0083] The first cavity and the second cavity are separated by a separation wall, and the separation wall is provided with a first communication port for communicating the first cavity and the second cavity. The first communication port is arranged at a position downstream of the condenser 301 or between the condenser 301 and the evaporator 302;

[0084] The first communication port is provided with an air door capable of being controlled to be opened and closed;

[0085] The base 7 is further provided with a second communication port for communicating the second cavity with the external environment, and the compressor is located on an air flow path between the first communication port and the second communication port.

[0086] In the embodiment, when the air door closes the first communication port, the heat generated by the compressor in the heat pump system 13 can be dissipated to the external environment through the second communication port. When the air door opens the first communication port, the fresh air in the external environment can enter the bottom air duct 5 through the second communication port and the first communication port under the action of the drying fan 2, and further enter the drum 1 under the action of the drying fan 2. In the process of introducing fresh air, the heat of the compressor can also be brought into the bottom air duct 5, thereby reducing the influence of the external airflow on the drying airflow temperature.

[0087] Optionally, in one implementation form of the embodiment, as shown in Figure 1 、 4 ,

[0088] The front support 8 is formed with a ring plate 11 around the barrel opening 10, and the ring plate 11 is provided with air supply holes 14 around the barrel opening 10 at intervals, which constitute the air inlet 101 and communicate with the barrel opening 10.

[0089] The drying fan 2 guides the drying air of the bottom air duct 5 into the front air duct 4 and into the barrel opening 10 through the air supply holes 14.

[0090] Preferably, a sealing ring is arranged between the outer edge portion of the ring plate 11 outside the air supply holes 14 and the barrel opening 10.

[0091] In the embodiment, by arranging the air supply holes 14 around the barrel opening 10 on the ring plate 11 at intervals, in the process of guiding the drying air of the bottom air duct 5 into the front air duct 4 by the drying fan 2 and into the barrel opening 10 through the air supply holes 14, the hot air is blown into the barrel along the barrel opening 10, the blowing angle is divergent and uniform, the air inlet is more divergent, and it will not be concentrated in a certain place. When the clothes in the drum 1 are less, the clothes are more stretched in the process of being blown to the center of the drum by the air of the air inlet 101 located in the front part of the drum 1, the drying efficiency is higher, and when the clothes are more scattered by the rotation of the drum 1, the clothes can be uniformly heated, the evaporation of water is accelerated, and thus the drying efficiency is improved. Further, the sealing ring avoids air leakage and improves the utilization rate of hot air.

[0092] Optionally, in one implementation form of the embodiment, as shown in Figure 4 ,

[0093] The front support 8 is provided with at least two rotation supports 12 arranged at intervals, and the drum 1 is rotatably supported on the at least two rotation supports 12.

[0094] In the embodiment, the rotation supports 12 can be two groups of pulleys, which are symmetrically arranged on both sides of the bottom of the drum 1. In the process of rotating the drum 1, the rotation supports 12 have friction with the pulleys, can drive the pulleys to rotate, and can provide effective rotation support for the rotation of the drum 1.

[0095] Optionally, in one implementation form of the embodiment, as shown in Figure 1 ,

[0096] The clothes dryer is also provided with a steam generator 9, which is installed in the front support 8, and the direction of spraying water vapor is sprayed from the barrel opening 10 to the inside of the drum 1.

[0097] In this embodiment, the steam generator 9 is installed in the front support 8, and the water vapor spraying direction is inward to the barrel opening 10. When the user puts less clothes into the drum 1, the clothes are blown to the center of the drum by the air at the air inlet 101 located at the front of the drum 1. At this time, the steam generator 9 is turned on, and the spraying of water vapor makes the fibers in the crimped state of the clothes gradually relax to the straight state to achieve the wrinkle removal of the clothes. Compared with the state of the clothes after being dried by the air outlet at the bottom of the drum, the clothes are more relaxed, and the air blown into the drum by the air inlet 101 located at the front of the drum is of a diverging type and will not be concentrated in a certain place. When the clothes are more and are shaken by the rotation of the drum 1, the clothes can be uniformly heated to accelerate the evaporation of moisture, thereby improving the drying efficiency. The problem that in the traditional clothes dryer, for example, the steam spraying direction is opposite to the air outlet direction at the bottom of the drum, and the corresponding effect can be achieved only by prolonging the care time is solved.

[0098] Optionally, in an implementation manner of the embodiment,

[0099] The heat exchange module 3 is provided with a box body, and the condenser 301 and the evaporator 302 are arranged in the box body.

[0100] The box body is formed with a groove at a position corresponding to the evaporator 302, and the front support 8 is provided with a water storage groove for providing water for the steam generator 9.

[0101] A communication channel is formed between the groove and the water storage groove, and a water pump is arranged in the communication channel or the water storage groove.

[0102] In this embodiment, the water pump can suck the water in the groove into the water storage groove, and the condensate water generated by the evaporator 302 is used to supply water for the steam generator 9, thereby improving the utilization efficiency of the condensate water and saving water resources.

[0103] Further, in order to improve the cleanliness of the condensate water, the groove includes an upper region and a lower region, and a filter screen is arranged between the upper region and the lower region. The condensate water generated by the evaporator 302 flows into the upper region, is filtered through the filter screen, and then enters the lower region. The water storage groove is in communication with the lower region.

[0104] In summary, the ingenious design of the clothes dryer is as follows:

[0105] Firstly, by designing the drying air duct to at least partially extend along the drum axis and be located below the drum, and by arranging the air inlet at the front of the drum and the air outlet at the rear of the drum, when the clothes in the drum are less, the clothes are blown to the center of the drum by the air at the air inlet located at the front of the drum. Compared with the state of the clothes after being dried by the air outlet at the bottom of the drum, the clothes are more relaxed, and the air blown into the drum by the air inlet located at the front of the drum is of a diverging type and will not be concentrated in a certain place. When the clothes are more and are shaken by the rotation of the drum 1, the clothes can be uniformly heated to accelerate the evaporation of moisture, thereby improving the drying efficiency.

[0106] Second, the air inlet is designed to surround the barrel opening, the hot air blown from the air inlet is more comprehensive and uniform, and the air inlet is more dispersed, which will not be concentrated in a certain place. When the clothes in the drum are less, the clothes are more stretched during the process of being blown by the air inlet in the front part of the drum to the center of the drum, and the drying efficiency is higher. When the clothes are more and the clothes are scattered during the rotation of the drum, the clothes can be uniformly heated, the evaporation of water is accelerated, and the drying efficiency is improved.

[0107] Third, the drying fan is arranged close to the air inlet and downstream of the heat exchange module on the drying air duct, so that the drying fan forms a front air inlet structure. Under the same power condition, the front air inlet structure has a shorter air inlet stroke and higher air inlet efficiency. During the drying process, the clothes can uniformly bring hot air to the surface of the clothes when the clothes rotate with the drum, the drying efficiency is improved, and the drying time is shortened.

[0108] Fourth, the front air duct, the bottom air duct and the rear air duct are arranged around the drum. This arrangement facilitates the front air inlet of the drum, reduces the occupation of the air duct in the cabinet of the clothes dryer, saves the space in the cabinet of the clothes dryer, and makes the internal structure of the clothes dryer compact.

[0109] Fifth, the heat pump system is provided with a communication port and the like, so that the heat generated by the compressor in the heat pump system can be dissipated to the external environment through the communication port. The fresh air in the external environment can also enter the bottom air duct through the communication port, and further enter the drum under the action of the drying fan. In the process of introducing fresh air, the heat of the compressor can also be brought into the bottom air duct, reducing the influence of external airflow on the drying airflow temperature.

[0110] Sixth, a groove is formed at the position of the evaporator, and a water storage tank is arranged on the front support, which provides steam water for the steam generator. The use efficiency of the condensate water is improved by using the condensate water generated by the evaporator to supply water to the steam generator 9, and water resources are saved.

[0111] It can be further understood that "multiple" in the disclosure means two or more, and other quantifiers are similar. "And / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can represent: A exists alone, A and B exist together, and B exists alone. The character " / " generally represents that the front and rear associated objects are in an "or" relationship. The singular form "a", "said" and "the" are also intended to include the plural form, unless the context clearly indicates otherwise.
