[0026] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although the embodiments described below are in conjunction with a clothes dryer, the technical solution of the present invention is also applicable to other clothing processing equipment with drying functions, such as washer-dryer combos.

[0027] It should be noted that in the description of this utility model, terms such as "left" and "right," which indicate direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Furthermore, it should be noted that in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connect," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] Specifically, this utility model provides a clothes dryer, such as Figure 1 As shown, the dryer of this utility model includes a housing (not shown in the figure), a drum 1 and a drying device. The drum 1 is rotatably installed in the housing, and the drying device is connected to the drum 1 and can deliver hot air into the drum 1 to dry the clothes in the drum 1.

[0030] Preferably, such as Figure 1 As shown, the drying device of this utility model includes a circulating air duct 2, a fan 4, and a heat pump module. The circulating air duct 2 is connected to the drum 1. The heat pump module includes a compressor, an evaporator 31, a condenser 32, a refrigerant pipeline, and a throttling element installed on the refrigerant pipeline. The refrigerant pipeline connects the compressor to the evaporator 31 and the condenser 32 to form a refrigerant circulation loop. The evaporator 31 and the condenser 32 are both installed in the circulating air duct 2. Along the airflow direction, the evaporator 31 is located upstream of the condenser 32. The fan 4 is used to make the airflow circulate in the drum 1 and the circulating air duct 2.

[0031] When the drying mode is executed, the fan 4 and the compressor of the heat pump module are started. Under the action of the fan 4, the airflow circulates between the drum 1 and the circulating air duct 2. The evaporator 31 is used to dehumidify the circulating airflow in the circulating air duct 2, and the condenser 32 is used to heat the airflow in the circulating air duct 2.

[0032] For example, such as Figure 1 As shown, the drum 1 is horizontally arranged, and the right end of the drum 1 has a drum opening 13 through which the user can put and take out clothes. The left end of the drum 1 is the rear drum wall 11 of the drum 1, which has multiple vents 12. The circulating air duct 2 is located below the drum 1. The air inlet of the circulating air duct 2 is set close to the drum opening 13, and the air outlet of the circulating air duct 2 extends to the rear drum wall 11 of the drum 1. The fan 4 is installed in the circulating air duct 2 and is set close to the air outlet of the circulating air duct 2. After the fan 4 is started, the hot and humid air in the drum 1 is discharged from the drum opening 13 of the drum 1 and enters the circulating air duct 2. When the hot and humid air flows through the evaporator 31, it exchanges heat with the evaporator 31. The moisture carried by the hot and humid airflow condenses. When the circulating airflow flows through the condenser 32, it absorbs the heat dissipated by the condenser 32, and the temperature rises. The high-temperature airflow returns to the drum 1 from the vents 12 on the rear drum wall 11 of the drum 1 and exchanges heat and moisture with the clothes in the drum 1.

[0033] It should be noted that the location of the fan 4 is not limited to the position near the air outlet of the circulating air duct 2 as described above. For example, it can also be located near the air inlet of the circulating air duct 2, or between the evaporator 31 and the condenser 32. In addition, the fan 4 can also be installed outside the circulating air duct 2. For example, the fan 4 can be located behind the drum 1, with the exhaust port of the fan 4 facing the rear wall 11 of the drum 1, and the air outlet of the circulating air duct 2 connected to the air inlet of the fan 4. Alternatively, the fan 4 can be located near the opening 13 of the drum 1, with the air inlet of the fan 4 facing the opening 13 of the drum 1, and the exhaust port of the fan 4 connected to the air inlet of the circulating air duct 2, etc. Such adjustments and changes to the specific location of the fan 4 do not deviate from the principle and scope of this utility model and should be limited to the protection scope of this utility model.

[0034] Furthermore, it should be noted that the circulating air duct 2 is not limited to being located below the roller 1. For example, the circulating air duct 2 can also be located above or on the side of the roller 1. Of course, the present invention preferably places the circulating air duct 2 below the roller 1.

[0035] Preferably, such as Figure 1 As shown, the circulating air duct 2 of the drying device of this utility model includes an air inlet duct 21, a heat exchange duct 22 and an air outlet duct 23 connected in sequence. The air inlet end of the air inlet duct 21 is located near the cylinder opening 13 of the drum 1. The evaporator 31 and the condenser 32 are both located in the heat exchange duct 22. The air outlet end of the air outlet duct 23 is located near the rear cylinder wall 11 of the drum 1.

[0036] For example, such as Figure 1 As shown, the air inlet duct 21 is located at the lower right of the drum 1. The air inlet duct 21 extends vertically, and its top end is its air inlet end, which is located near the drum opening 13 of the drum 1. The bottom end of the air inlet duct 21 is connected to the right end of the heat exchange duct 22. The heat exchange duct 22 is located directly below the drum 1. The heat exchange duct 22 extends horizontally and is parallel to the axis of the drum 1. The evaporator 31 and condenser 32 of the heat pump module are both installed in the heat exchange duct 22. The air outlet duct 23 is located at the lower left of the drum 1. The air outlet duct 23 also extends vertically, and its top end is its air outlet end, which is located near the rear drum wall 11 of the drum 1. The bottom end of the air outlet duct 23 is connected to the left end of the heat exchange duct 22. The fan 4 is installed in the air outlet duct 23.

[0037] Preferably, such as Figure 1 and Figure 2As shown, the drying device of this utility model also includes an electric heating module 5, which is installed in the circulating air duct 2. The electric heating module 5 includes a plurality of strip-shaped heating members 51 that are spaced apart along a first direction. The strip-shaped heating members 51 extend along a second direction, which is perpendicular to the first direction. The plurality of strip-shaped heating members 51 are arranged in parallel.

[0038] Along the direction of airflow, the electric heating module 5 is located downstream of the condenser 32 and preferably upstream of the fan 4, that is, the electric heating module 5 is preferably located between the condenser 32 and the fan 4.

[0039] By setting multiple parallel strip heating elements 51 in the circulating air duct 2, even if one strip heating element 51 is damaged, the remaining strip heating elements 51 can continue to work, extending the service life of the electric heating module 5. Furthermore, the use of multiple parallel strip heating elements 51 increases the overall heating power and speed of the electric heating module 5, which is beneficial to improving the drying efficiency of the dryer. In addition, the distribution of multiple strip heating elements 51 in the circulating air duct helps to achieve uniform heating and avoid problems such as local overheating or uneven heating. Moreover, during the drying mode, the power of the electric heating module can be adjusted as needed. For example, when a higher heating power is required, multiple strip heating elements 51 can be connected to the power supply. When the required heating power is not high, one or more strip heating elements 51 can be disconnected from the power supply, allowing only a portion of the strip heating elements 51 to work.

[0040] For example, such as Figure 2 As shown in the figure, the X direction is the first direction, the Y direction is the second direction, and there are 7 strip heating elements 51. The 7 strip heating elements 51 are distributed at intervals along the X direction, and preferably the 7 strip heating elements 51 are evenly distributed along the X direction. Each strip heating element 51 extends along the Y direction.

[0041] It should be noted that the number of strip heating elements 51 is not limited to the aforementioned 7. For example, those skilled in the art can set the number of strip heating elements 51 to 2, 3, 4, 5, 8, 9, 10 or more in practical applications. Of course, the present invention preferably sets the number of strip heating elements 51 to 5 to 10.

[0042] In addition, it should be noted that, in practical applications, those skilled in the art can configure the strip heating element 51 as an electric heating wire, an electric heating tube, or an electric heating rod, etc.

[0043] Furthermore, it should be noted that this utility model does not limit the length and diameter of the strip heating member 51. Those skilled in the art can flexibly set the specific values ​​of the length and diameter of the strip heating member 51 according to actual needs in practical applications.

[0044] Preferably, such as Figure 2 As shown, the length of the strip-shaped heating component 51 of the electric heating module 5 of this utility model is 100mm to 200mm.

[0045] For example, those skilled in the art can set the length of the strip heating member 51 to any value among 100mm, 110mm, 120mm, 130mm, 140mm, 150mm, 160mm, 170mm, 180mm, 190mm or 200mm in practical applications.

[0046] Preferably, such as Figure 2 As shown, the diameter of the strip-shaped heating element 51 of the electric heating module 5 of this utility model is 0.3mm to 1.0mm.

[0048] Preferably, such as Figure 1 and Figure 2 As shown, the plane containing the plurality of strip-shaped heating components 51 of the electric heating module 5 of this utility model is perpendicular to the direction of airflow.

[0049] By aligning the plane containing the multiple strip heating elements 51 perpendicular to the direction of airflow, the airflow can pass perpendicularly through the plane containing the multiple strip heating elements 51, resulting in more thorough contact and improved heating efficiency of the airflow, thereby increasing drying efficiency.

[0050] Preferably, such as Figure 1 and Figure 2 As shown, the electric heating module 5 of this utility model also includes a housing 52, and the strip-shaped heating member 51 is installed in the housing 52. The housing 52 has an air inlet 5211 and an air outlet 5221. The plane of the air inlet 5211 is perpendicular to the plane of the air outlet 5221.

[0051] For example, the electric heating module 5 is installed at the connection between the heat exchange duct 22 and the air outlet duct 23. The air inlet 5211 of the electric heating module 5 is located in the heat exchange duct 22, the plane on which the air inlet 5211 is located is a vertical plane, and the air inlet 5211 faces the condenser 32.

[0054] Preferably, such as Figure 1 and Figure 2 As shown, the electric heating module 5 of this utility model has an air guide 523 at the corner of the housing 52. The air guide 523 is located between the air inlet 5211 and the air outlet 5221. The air guide 523 can change the flow direction of the airflow so that the airflow entering from the air inlet 5211 flows more smoothly toward the air outlet 5221.

[0055] By setting an air guide 523 at the corner of the housing 52 to change the direction of airflow, the airflow entering from the air inlet 5211 of the housing 52 can flow more smoothly toward the air outlet 5221 of the housing 52, reducing flow loss and improving the drying efficiency of the dryer and reducing drying time.

The air inlet 5211 of the electric heating module 5 is located at one end of the first housing 521, and the air outlet 5221 of the electric heating module 5 is located at one end of the second housing 522. The other end of the first housing 521 is connected to the other end of the second housing 522.
