DETAILED DESCRIPTION

[0038] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0039] The present application provides a drying channel assembly and a clothes processing device to solve the problem that in the related art, the air outlet of the cover shell is usually sealed by a sealing member against the air inlet end of the drying channel shell, and due to problems such as inaccurate assembly alignment and part size deviation, the connection between the air outlet of the cover shell and the air inlet end of the drying channel shell is prone to poor sealing, resulting in air leakage at the connection, affecting the normal use of the drying channel assembly.

[0040] In a first aspect, the present application provides a drying channel assembly, as shown in Figures 1 to 3 The drying channel assembly includes a drying channel shell 10, an impeller assembly 20, and a heating member 30.

[0041] The drying channel shell 10 has an airflow channel 11, and the two ends of the airflow channel 11 form an air inlet 111 and an air outlet 112, respectively; the drying channel shell 10 is a shell for forming the airflow channel 11, and the drying channel shell 10 can be formed of plastic, metal, or other materials; the airflow channel 11 is formed in the drying channel shell 10, and the airflow channel 11 can be a straight channel, a curved channel, or other shapes.

[0042] The impeller assembly 20 is located in the drying channel shell 10 and connected with the drying channel shell 10, and is used to generate air flow in the air flow channel 11 from the air inlet 111 to the air outlet 112; the impeller assembly 20 can rotate in the air flow channel 11 to provide power for air flow, so as to generate air flow in the air flow channel 11 from the air inlet 111 to the air outlet 112.

[0043] The heating element 30 is located in the drying channel shell 10 and connected with the drying channel shell 10, and is located downstream of the impeller assembly 20; the heating element 30 is used to heat the air flowing through the heating element 30 in the air flow channel 11 to become high-temperature air, and the heating element 30 can be a PTC heating element, an electric heating tube, an electric heating wire or other devices that can heat air; the heating element 30 is located downstream of the impeller assembly 20, which means that in the path of the air flow along the air flow channel 11, the heating element 30 is located downstream of the impeller assembly 20; when the impeller assembly 20 is started, air flow is generated in the air flow channel 11, the air flow enters the air flow channel 11 from the air inlet 111, and then passes through the impeller assembly 20 and the heating element 30 in turn, the air flow passing through the heating element 30 is heated by the heating element 30 to form high-temperature gas, and then the high-temperature gas is discharged through the air outlet 112, and the high-temperature gas can be used for drying treatment of clothes and other articles.

[0044] It should be noted that in the present application, the impeller assembly 20 is directly arranged in the air flow channel 11 of the drying channel shell 10, and the drying channel shell 10 is reused as a cover shell of the impeller assembly 20, so that an additional cover shell for the impeller assembly 20 is not needed, and the sealing performance of the connection between the air outlet of the cover shell and the air inlet end of the drying channel shell 10 does not need to be considered, thereby avoiding the problem of poor sealing at the connection between the air outlet of the cover shell and the air inlet end of the drying channel shell 10, and reducing the number of parts of the drying channel assembly and making the assembly of the drying channel assembly more convenient; in addition, the impeller assembly 20 and the heating element 30 are integrated in the drying channel shell 10, so that the integration degree of the drying channel assembly is higher and the volume is smaller.

[0045] In some embodiments, the drying channel assembly is applied to a clothes treatment device, and the air inlet 111 is used to directly suck air outside the body of the clothes treatment device into the air flow channel 11. It should be noted that the air inlet 111 is used to directly suck air outside the body into the air flow channel 11, which means that the air inlet 111 is located outside the body and directly contacts and communicates with the air outside the body, and the air inlet 111 does not need to communicate with the air outside the body through an additional pipeline assembly; when the drying channel assembly is started, the air outside the body is directly sucked into the air flow channel 11 through the air inlet 111, without passing through other additional pipeline assemblies.

[0046] It should be noted that in the related art, when the drying duct assembly is applied to a laundry treating apparatus such as a washing machine, the blower fan and the drying duct shell are both installed in the body of the laundry treating apparatus, and the drying duct shell is in communication with a laundry treating cavity in the laundry treating apparatus for treating laundry. Taking the laundry treating apparatus as a washing machine, since the blower fan and the drying duct shell are two independent components, the air outlet of the cover shell and the air inlet end of the drying duct shell are usually connected by a sealing strip, and the connection between the cover shell and the drying duct shell is prone to sealing failure. In addition, the cover shell itself does not have sealing properties. When the laundry treating cavity has a bubble overflow problem, the bubbles will enter the drying duct shell through the communication opening between the drying duct shell and the laundry treating cavity, and then flow into the connection between the cover shell and the drying duct shell and the cover shell. The bubbles will flow into the body of the washing machine from the poorly sealed area and the opening of the cover shell, causing problems such as short circuit of the washing machine.

[0047] In the present application, the air inlet 111 is used to directly suck air outside the body into the airflow channel 11, and the impeller assembly 20 is directly arranged in the airflow channel 11 of the drying duct shell 10. When the drying duct assembly is applied to a laundry treating apparatus, the air outlet 112 can be in communication with a laundry treating cavity, and the air inlet 111 can be arranged outside the body. In this way, even if a bubble overflow problem occurs, the bubbles entering the drying duct shell 10 through the air outlet 112 can be directly discharged to the outside of the body through the air inlet 111, which can prevent the bubbles from flowing into the body through the drying duct assembly as a flow channel, causing problems such as short circuit of the laundry treating apparatus.

[0048] As shown in FIG. 1, Figures 2 to 4 In some embodiments, the drying duct shell 10 includes a first portion 191 and a second portion 192, the second portion 192 is located on one side of the first portion 191 along the axial direction of the impeller assembly 20 and is connected to the first portion 191. The airflow channel 11 includes a first flow channel 113 located in the first portion 191 and a second flow channel 114 located in the second portion 192. One end of the first flow channel 113 forms the air outlet 112, and the impeller assembly 20 is located in the first flow channel 113. The first end of the second flow channel 114 forms the air inlet 111, and the second end of the second flow channel 114 forms an air passage 114a in communication with the first flow channel 113. The direction of the air passage 114a is different from the direction of the air inlet 111.

[0049] It should be noted that the orientation of the vent 114a is the extension direction of the center line of the vent 114a, and when the vent 114a is circular, the center line of the vent 114a is the axis of the vent 114a. Similarly, the orientation of the air inlet 111 is the extension direction of the center line of the air inlet 111, and when the air inlet 111 is circular, the center line of the air inlet 111 is the axis of the vent 114a. The orientation of the vent 114a is different from the orientation of the air inlet 111, that is, the orientation of the vent 114a is not parallel to the orientation of the air inlet 111, so that the second flow channel 114 is a non-linear flow channel (the second flow channel 114 can be L-shaped, Z-shaped, curved or other shapes), and the orientation of the vent 114a and the orientation of the air inlet 111 can form an angle of 15 degrees, 30 degrees, 45 degrees, 60 degrees, 75 degrees or other angles.

[0050] It should also be noted that the second part 192 can act as an extension of the drying channel shell 10, so that the air inlet 111 is more easily extended out of the body to be located outside the body. In addition, compared to directly positioning the air inlet of the impeller assembly 20 opposite the air inlet 111, the distance between the air inlet of the impeller assembly 20 and the air inlet 111 is short, and there is no obstruction. When foreign matter outside the drying channel shell 10 falls into the airflow passage 11 through the air inlet 111, the foreign matter is likely to contact the impeller assembly 20 through the air inlet 111, causing damage to the impeller assembly 20. When the air inlet 111 is provided outside the body, the user's limbs are likely to contact the impeller assembly 20 through the air inlet 111, causing a safety accident. In the present embodiment, the second flow channel 114 is a non-linear flow channel, the distance between the air inlet of the impeller assembly 20 and the air inlet 111 is long, and the bent second flow channel 114 can effectively protect the impeller assembly 20. Foreign matter is not likely to contact the impeller assembly 20 through the second flow channel 114, and the user's limbs are also not likely to contact the impeller assembly 20 through the second flow channel 114, thereby preventing foreign matter from damaging the impeller assembly 20 and preventing the impeller assembly 20 from injuring the body to cause a safety accident. As Figures 2 to 4As shown, in some embodiments, the drying tunnel shell 10 comprises a first shell 12 and a second shell 13 arranged oppositely, the first shell 12 and the second shell 13 are detachably connected to enclose the airflow channel 11, and the impeller assembly 20 is located between the first shell 12 and the second shell 13. It can be understood that the first shell 12 and the second shell 13 can be disassembled, so that when the impeller assembly 20 and the heating element 30 are installed, the impeller assembly 20 and the heating element 30 can be installed on one of the first shell 12 and the second shell 13 first, and then the first shell 12 and the second shell 13 are spliced, so that the installation of the impeller assembly 20 and the heating element 30 in the airflow channel 11 is more convenient. It should be noted that the second part 192 can be formed by part of the first shell 12, and the first part 191 can be formed by the whole of the second shell 13 and other parts of the first shell 12.

[0051] Further, the first shell 12 has a first splicing surface 121 facing the second shell 13, and the second shell 13 has a second splicing surface 131 facing the first shell 12, the first splicing surface 121 and the second splicing surface 131 are fitted, so that the first splicing surface 121 and the second splicing surface 131 are connected more tightly, and the gap between the first splicing surface 121 and the second splicing surface 131 is reduced.

[0052] Among them, one of the first splicing surface 121 and the second splicing surface 131 is provided with a clamping protrusion 14, and the other is provided with a clamping groove 15, the clamping groove 15 is provided with a sealing element 16, the clamping protrusion 14 is clamped in the clamping groove 15 and presses the sealing element 16 to realize the sealed connection of the first shell 12 and the second shell 13. It can be understood that the first shell 12 and the second shell 13 are detachably connected through the cooperation of the clamping protrusion 14 and the clamping groove 15, and the sealing element 16 is used to ensure the sealing of the connection between the clamping protrusion 14 and the clamping groove 15, so that the sealing reliability of the connection between the first shell 12 and the second shell 13 is higher.

[0053] It should be noted that when the clamping protrusion 14 is arranged on the first shell 12, the clamping groove 15 is arranged on the second shell 13, and the clamping protrusion 14 can be integrally formed with the first shell 12 to eliminate the gap at the connection between the clamping protrusion 14 and the first shell 12, and improve the overall sealing performance of the drying tunnel shell 10. When the clamping protrusion 14 is arranged on the second shell 13, the clamping groove 15 is arranged on the first shell 12, and the clamping protrusion 14 can be integrally formed with the second shell 13.

[0054] Specifically, the first shell 12 has a first groove with a notch on the first joint surface 121, and the second shell 13 has a second groove with a notch on the second joint surface 131. When the first shell 12 is connected with the second shell 13, the first groove and the second groove are in communication to form the airflow channel 11. The clamping protrusions 14 and the clamping grooves 15 can surround the first shell 12 in a circle. The shape of the clamping protrusions 14 matches the shape of the clamping grooves 15, so that the connection between the first shell 12 and the second shell 13 is more secure. The sealing member 16 can be a sealing strip surrounding the clamping grooves 15 in a circle, so as to improve the sealing performance of the connection between the clamping protrusions 14 and the clamping grooves 15. The sealing member 16 can be formed of metal, rubber, plastic or other materials.

[0055] In some embodiments, the impeller assembly 20 includes a shaft core 21, a blade set (not shown in the figure) and a driving member (not shown in the figure). The shaft core 21 is used to provide a mounting position and support for the blade set. The blade set includes a plurality of blades arranged at intervals around the periphery of the shaft core 21, and the blades are connected with the shaft core 21. The driving member is connected with the drying channel shell 10 and is in transmission connection with the shaft core 21. The driving member is used to drive the shaft core 21 to rotate, so as to drive the blades to rotate, and then generate airflow in the airflow channel 11 flowing from the air inlet 111 to the air outlet 112. The driving member can be an electric motor or a motor. When the blades rotate, the air in the airflow channel 11 is disturbed, so as to generate airflow. The specific working principle of the impeller assembly 20 to generate airflow has been disclosed in the related art, and will not be described here. It can be understood that the driving member is also integrated in the airflow channel 11, so that the integration degree of the drying channel assembly is higher, and the volume is smaller.

[0056] It should be further pointed out that, as shown in Figure 2 and Figure 3 , the impeller assembly 20 can be a centrifugal impeller assembly, which can realize axial air inlet and radial air outlet. Of course, in other embodiments, the impeller assembly 20 can also be an axial flow impeller assembly, which can realize axial air inlet and axial air outlet.

[0057] In some embodiments, the impeller assembly 20 is arranged close to the air inlet 111. The distance between the impeller assembly 20 and the air inlet 111 is greater than the distance between the impeller assembly 20 and the air outlet 112. Therefore, the impeller assembly 20 is arranged near the air inlet 111 and has a long distance from the air outlet 112. When the drying channel assembly is applied to a clothes treatment apparatus, a small degree of overflow occurs, and less foam flows into the airflow channel 11. When the foam flows, it can be evaporated and blocked by the heating member 30, so as to prevent the foam from flowing to the impeller assembly 20 and causing rust and other problems of the impeller assembly 20.

[0058] Continuing to refer to Figure 2 and Figure 3As shown, in some embodiments of the present application, the drying duct assembly further comprises a heat insulation member 40, which is located in the drying duct shell 10, and the drying duct shell 10 is connected, and the heating member 30 is arranged on the heat insulation member 40, and the heat insulation member 40 separates the heating member 30 from the inner wall of the airflow channel 11, and the heat insulation member 40 can play a heat insulation role, can block the heat transfer between the heating member 30 and the drying duct shell 10, and prevent the direct contact between the heating member 30 and the drying duct shell 10 from causing the temperature of the drying duct shell 10 to be too high. Wherein, the heat insulation member 40 can be formed of high-temperature-resistant plastic (such as polyphenylene sulfide, polyphenyl ether, polysulfone, etc.), board or other materials.

[0059] In some embodiments, the inner wall of the airflow channel 11 is provided with a mounting groove 17, and at least part of the heat insulation member 40 is clamped in the mounting groove 17, so as to realize the mounting and fixing of the heat insulation member 40 by the mounting groove 17, thereby realizing the mounting and fixing of the heating member 30.

[0060] In some embodiments, the heat insulation member 40 is clamped and fixed between the first shell 12 and the second shell 13, so as to fix the heat insulation member 40 through the first shell 12 and the second shell 13, thereby fixing the heating member 30, so that the installation of the heat insulation member 40 and the heating member 30 is more stable, and the heat insulation member 40 and the heating member 30 are prevented from loosening.

[0061] In some embodiments, the heat insulation member 40 can be sleeved on the end of the heating member 30, and the two sides of the heat insulation member 40 are in contact with the first shell 12 and the second shell 13 respectively, so as to separate the heating member 30 from the first shell 12 and the second shell 13. The heat insulation member 40 can also be provided with a heat dissipation opening 41, so that the heat generated by the heating member 30 can be fully dissipated.

[0062] Continuing to refer to Figure 2 and Figure 3 As shown, in some embodiments of the present application, the drying duct assembly further comprises a temperature measuring member 50, which comprises a temperature measuring probe 51 located in the drying duct shell 10, and the temperature measuring probe 51 is located downstream of the heating member 30. The temperature measuring probe 51 can measure the temperature of the air flowing through the heating member 30 and flowing towards the air outlet 112, so as to prevent the temperature of the air discharged from the air outlet 112 from being too high to cause damage to the clothes and other objects. Wherein, the temperature measuring member 50 can be an NTC (Negative Temperature Coefficient) temperature sensor, a thermocouple temperature sensor, an infrared radiation temperature sensor or other types of temperature sensors.

[0063] In some embodiments, the drying duct shell 10 can be provided with a mounting hole 18, and the temperature measuring member 50 is arranged in the mounting hole 18 to seal the mounting hole 18 and realize the mounting and fixing of the temperature measuring member 50.

[0064] In a second aspect, based on the above drying duct assembly, the present application further provides a laundry treating apparatus, which comprises a machine body and the drying duct assembly according to any one of the above embodiments, the machine body has a laundry treating cavity, the drying duct shell 10 is mounted on the machine body, and the air outlet 112 is in communication with the laundry treating cavity. The laundry treating apparatus can be a washing machine, a dryer or other apparatuses with drying function.

[0065] In some embodiments, the air inlet 111 is located outside the machine body. When the overflow problem occurs in the laundry treating cavity, even if the foam enters the drying duct shell 10 through the air outlet 112, the foam in the drying duct shell 10 can be directly discharged to the outside of the machine body through the air inlet 111, which can prevent the foam from flowing into the machine body through the drying duct assembly as a flow channel, thereby preventing the short circuit problem and other problems.

[0066] In some embodiments, the laundry treating apparatus is a small laundry treating apparatus such as a desktop laundry treating apparatus or a mini laundry treating apparatus.

[0067] In some embodiments, the laundry treating apparatus is a washing machine, a dryer or a washer-dryer.

[0068] The above merely describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
