Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of electrical appliances, and particularly relates to a clothes processing device. BACKGROUND

[0002] In the related art, clothes processing devices with a drying function mostly take in air from the front end of a cylinder and discharge air from the rear end. However, for a miniaturized clothes processing device, the space at the front end of the cylinder is insufficient, which affects the air inflow of the drying airflow and in turn affects the drying efficiency of clothes.

[0003] To solve the above technical problems, the applicant designs a clothes processing device that takes in air from the rear end of a cylinder and discharges air from the side, so as to improve the drying efficiency of a miniaturized clothes processing device. However, how to ensure that the airflow directly enters the inner cylinder from the outer cylinder is a technical problem to be solved. SUMMARY

[0004] The present application provides a clothes processing device, which aims to at least partly improve the drying efficiency of the clothes processing device.

[0005] The present application provides a clothes processing device, which comprises a drying module including an output part, an outer cylinder including an air inlet part and an air outlet part, the air inlet part of the outer cylinder being arranged at the axial rear end of the outer cylinder, the air outlet part of the outer cylinder being arranged at the side of the outer cylinder, and an inner cylinder rotatably arranged in the outer cylinder, the axial rear end of the inner cylinder being provided with an air inlet hole, and the side of the inner cylinder being provided with an air outlet hole, wherein the air inlet part of the outer cylinder is connected to the output part of the drying module, and the axial rear end of the inner cylinder is sealingly connected to the axial rear end of the outer cylinder.

[0006] The clothes processing device provided by the present application can guide the drying airflow introduced from the air inlet part of the outer cylinder into the inner cylinder through the air inlet hole of the inner cylinder to dry the clothes in the inner cylinder. Since the axial rear end of the inner cylinder is directly and sealingly connected to the axial rear end of the outer cylinder, the direction of the drying airflow can be ensured, so that the drying airflow can only enter the inner cylinder from the axial rear end of the inner cylinder, thereby avoiding the diffusion of the drying airflow and improving the drying efficiency.

[0034] In order for those skilled in the art to which the present application pertains to more clearly understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0035] With the increasing popularity of smart home in daily life, laundry treating devices such as washing machines have become an important lifestyle. The laundry treating device with drying function is relatively large in size and occupies a large use space, and therefore a small laundry treating device is applied.

[0036] In the related art, the laundry treating device with drying function mostly takes air from the front end of the cylinder and discharges air from the rear end. However, for the small laundry treating device, the front end of the cylinder is insufficient in space due to the setting of the drop port. If the air inlet part for introducing drying airflow is arranged at the front end of the cylinder, in order to avoid the drop port, the size of the air inlet part is small, which affects the air inlet amount of the drying airflow and further affects the drying efficiency of the laundry.

[0037] Based on the above technical problems, the laundry treating apparatus provided by the present application has the design idea that the rear end of the drum is provided with an air inlet part for introducing the drying airflow. In this way, the air inlet part is not affected by the dropping opening at the front end of the drum, and the size of the air inlet part can be large enough to ensure the air inlet amount of the drying airflow into the drum, thereby improving the drying efficiency of the laundry. The related details of the laundry treating apparatus are further described with reference to the drawings.

[0038] Figure 1 The structural schematic diagram of the laundry treating apparatus in one or more embodiments of the present application is shown, Figure 2 The structural schematic diagram of the base 10 in Figure 1 is shown. In combination with Figure 1 and Figure 2 , according to an embodiment of the present application, the laundry treating apparatus comprises a base 10, which is a carrier of the laundry treating apparatus and is used to assemble the remaining components of the laundry treating apparatus. The base 10 is provided with an air guide part 101. In an embodiment, the air guide part 101 is an air inlet grille at the center of the base 10. The air inlet grille can be provided with two places, and air can enter the laundry treating apparatus through the air inlet part 502. In another embodiment, the air guide part 101 can also be provided at the edge of the base 10, or the air guide part 101 can be provided at both the edge and the center of the base 10, which is not limited in the present application.

[0039] In combination with Figure 2 , according to an embodiment of the present application, the edge of the bottom of the shell is provided with a damping member 20. On the one hand, the damping member 20 can improve the anti-shock ability of the apparatus, and on the other hand, the damping member 20 can also provide a certain gap between the base 10 and the installation ground, so that air can be introduced into the laundry treating apparatus through the air guide part 101 on the bottom.

[0040] Figure 3 The assembly schematic diagram of the cover 30 and the base 10 in Figure 1 is shown. In combination with Figure 3 , according to an embodiment of the present application, the laundry treating apparatus further comprises a cover 30, which is connected to the base 10. The cover 30 constitutes the appearance of the laundry treating apparatus. The cover 30 and the base 10 constitute an assembly space, and the drum 50 and the drying module 70 and other components of the laundry treating apparatus are assembled in the assembly space. Specifically, the cover 30 is connected to the edge of the base 10. The front side of the cover 30 is provided with a through opening 301. The door body 40 of the laundry treating apparatus is reversibly connected to the edge of the through opening 301 of the cover 30. The door body 40 can open and close the through opening 301 of the cover 30, so as to facilitate the user to take and place the laundry.

[0041] Figure 4 The structural schematic diagram of Figure 1 with the cover 30 removed is shown. In combination with Figure 4According to an embodiment of the present application, the laundry treating apparatus further comprises a drum 50, which is assembled on the base 10 and located in the cover 30. In practice, the drum 50 is rigidly connected to the base 10 through the support frame 60, so as to reduce the vibration of the drum 50 to some extent and improve the reliability of the laundry treating apparatus during operation.

[0042] In combination with Figure 4 According to an embodiment of the present application, the axial front end of the drum 50 is provided with a feeding opening 501, which is oppositely arranged with the through opening 301 of the cover 30, so as to take or put the laundry into the drum 50 through the feeding opening 501. When the door 40 closes the through opening 301 of the cover 30, the door 40 also seals the feeding opening 501 of the drum 50.

[0043] In combination with Figure 4 According to an embodiment of the present application, the drum 50 is arranged in an inclined manner, i.e. the axial front end of the drum 50 is higher than the axial rear end of the drum 50, so as to raise the axial front end of the drum 50 and then raise the height of the feeding opening 501 at the axial front end of the drum 50, thereby facilitating the user to take or put the laundry. In addition, since the axial rear end of the drum 50 is lower, the laundry is gathered at the axial rear end of the drum 50 during operation of the laundry treating apparatus, and the drying air flow entering from the axial rear end of the drum 50 can directly act on the laundry in the drum 50, so as to improve the drying efficiency of the laundry treating apparatus to some extent. According to another embodiment of the present application, the drum 50 can also be arranged in a horizontal manner.

[0044] Figure 5 A structural schematic view of the outer drum 503 of the drum 50 in Figure 4 In combination with Figure 5 According to an embodiment of the present application, the axial rear end of the drum 50 is provided with an air inlet, which serves as an air inlet portion 502 of the drum 50, so that the drying air flow can enter into the drum 50 through the air inlet portion 502 at the axial rear end of the drum 50, so as to dry the laundry in the drum 50. In practice, the air inlet portion 502 can be arranged at the lower side of the axial rear end of the drum 50, since the drying air flow has a certain temperature, so that the drying air flow can be used to dry the laundry by flowing upward, so as to improve the drying effect of the laundry as much as possible. In practice, the air inlet portion 502 is substantially in the shape of a sector, which extends upward from the part of the edge at the lower side of the axial rear end of the drum 50 close to the bottom to the middle region of the drum 50, so as to improve the air inlet amount of the air inlet portion 502 of the drum 50 as much as possible and improve the drying effect.

[0045] Figure 6 A structural schematic view of the drum 50 and the drying module 70 in Figure 4 In combination with Figure 6According to one embodiment of this application, the clothing processing equipment further includes a drying module 70. The drying module 70 is provided with an output section. The output section of the drying module 70 is connected to the air inlet section 502 of the drum 50. The drying module 70 generates a drying airflow. The drying airflow is input into the drum 50 through the air inlet section 502 of the drum 50 to dry the clothes inside the drum 50.

[0046] Combination Figure 6 According to one embodiment of this application, the drying module 70 is integrated on the outer surface of the cylinder 50, that is, the drying module 70 is mounted on the cylinder 50 to minimize the space occupied by the drying module 70.

The output of the air-guiding component 701 is connected to the air inlet 502 of the cylinder 50 through the air-guiding duct 703. The heating component 702 is disposed inside the air-guiding duct 703, that is, the heating component 702 is disposed between the output of the air-guiding component 701 and the air inlet 502 of the cylinder 50, and the heating component 702 is disposed downstream of the air-guiding component 701. When the heating component 702 is working, air is introduced into the heating duct through the air inlet 502 of the base 10, and then heated by the air-guiding component 701 in the heating duct to generate a drying airflow. The drying airflow is introduced into the cylinder 50 through the air inlet 502 at the axial rear end of the cylinder 50 to dry the clothes inside the cylinder 50. According to one embodiment of this application, the heating element 702 can also be disposed upstream of the air duct 701. That is, a pipe can be disposed upstream of the air duct 701, and the heating element 702 can be disposed in the pipe, which can also achieve the goal of heating the air into a drying airflow. In specific implementation, the air duct 701 can be a fan, and the heating element 702 can be an electric heater, such as an electric heating wire or an electric heating tube.
