[0032] The laundry treatment device is widely used in daily life, which is used for washing clothes or drying clothes. The laundry treatment device mainly includes a drum. During the washing process or the drying process, water flow will flow in the drum. For example, during the washing process, external water enters the inner drum, and after the washing is completed, the water is discharged to the outside of the inner drum. During the drying process, some impurities will be attached to the air outlet passage. In order to improve the drying effect, the water flushing of the air outlet passage or the condensate water discharge may exist during the drying process. Since the air outlet passage is communicated with the drum through the air outlet, the water and impurities are easy to flow back to the drum, which causes the clothes to be polluted again.

[0033] The inner drum and the laundry treatment device provided by the embodiment of the present application can improve the above-mentioned problems. The drum and the laundry treatment device provided by the embodiment of the present application can directly discharge the water and impurities from the outside of the drum during the flushing of the air outlet passage, which can reduce the possibility of the water and impurities entering the drum, reduce the secondary pollution of the clothes, and improve the washing and drying effect.

[0034] The present application will be described below in conjunction with the drawings and specific embodiments:

[0035] Please refer to Figure 1 and Figure 2 , Figure 1 shows a rear view of the drum 100, Figure 2 shows Figure 1 the cross-sectional view at A-A in FIG. 1. The present application provides a drum 100. The drum 100 provided by the embodiment of the present application is applied to a laundry treatment device 10. The laundry treatment device 10 can be a washing machine, a dryer or a washing-drying integrated machine. The drum 100 provided by the embodiment of the present application can reduce the risk of clothes in the drum body 110 being wetted and polluted during the drying process, and can improve the drying effect of the clothes.

[0036] In the embodiment of the present application, the drum 100 comprises a barrel 110, a cover 120 and a drainage passage 130. The barrel 110 has an air outlet 112c. The cover 120 is arranged outside the barrel 110 and has an air outlet passage 121 communicating with the air outlet 112c. The drainage passage 130 is arranged outside the barrel 110 and communicates with the air outlet passage 121.

[0037] The barrel 110 is the main structure of the entire drum 100 and can provide a mounting basis for the cover 120 and the drainage passage 130. The barrel 110 can comprise an inner barrel 113 and an outer barrel 114. The inner barrel 113 is arranged inside the outer barrel 114. The inner barrel 113 has a containing cavity for containing clothes. The cover 120 and the air outlet 112c are arranged on the outer barrel 114. The inner barrel 113 is provided with water-permeable holes 112d communicating with the air outlet 112c. The cover 120 is provided with the air outlet passage 121 for communicating with the drying module 200. The humid and cold air in the barrel 110 can enter the drying module 200 through the air outlet passage 121. After being dehumidified and heated by the drying module 200, the dry and hot air enters the barrel 110 to exchange heat with the air in the barrel 110. The humid and cold air enters the drying module 200 through the air outlet passage 121. In this way, the clothes in the barrel 110 can be dried.

[0038] It should be noted that the clothes can be clothes, trousers, shoes, socks and other articles of clothing, bedclothes, bedspreads, pillowcases and other bedding, curtains, sofa covers and other household items.

[0039] The cover 120 is mainly connected between the outer barrel 114 and the drying module 200 and is used to guide the air in the outer barrel 114 to the drying module 200 through the air outlet passage 121. The shape of the cover 120 can be determined according to the relative positions of the barrel 110 and the drying module 200. The cover 120 can be connected to the air outlet 112c of the barrel 110 and the drying module 200.

[0040] For example, if the air outlet 112c is arranged at the bottom of the outer barrel 114 and the drying module 200 is arranged at the top of the barrel 110, one end of the cover 120 is connected to the air outlet 112c and the other end is connected to the drying module 200. The cover 120 can be arranged vertically or along the contour of the outer barrel 114. The cover 120 can be connected to the air outlet 112c and the drying module 200.

[0041] In the embodiment of the present application, the terms upper, lower, top and bottom refer to the positional relationship of the barrel 110 in the working state.

[0042] Please refer to Figure 2 and Figure 3 ,Figure 3 The axial view of the drum 100 is shown. Among them, the air outlet 112c can be arranged on the bottom surface 112b of the outer cylinder 114, and the bottom surface 112b refers to the side opposite to the opening 112a, that is, the bottom surface 112b refers to the wall opposite to the opening 112a, and the bottom surface 112b is not the lowest end of the cylinder body 110 in the use process. The bottom surface 112b can be the lowest end of the entire cylinder body 110, or can not be the lowest end of the cylinder body 110.

[0043] For example, when the axis of the cylinder body 110 is in the vertical direction, the bottom surface 112b is arranged below the opening 112a, when the axis of the cylinder body 110 is in the horizontal direction, the bottom surface 112b and the opening 112a are both arranged vertically, and if the opening 112a is arranged in front of the cylinder body 110, the bottom surface 112b is arranged at the rear of the cylinder body 110. In the embodiments of the present application, the cylinder body 110 is horizontally arranged as an example.

[0044] At least part of the air outlet 112c is arranged on the bottom surface 112b, which can be that the air outlet 112c is entirely arranged on the bottom surface 112b, or part of the air outlet 112c is arranged on the bottom surface 112b, or part of the air outlet 112c is arranged on other positions, as long as the air outlet 112c can communicate the containing cavity and the air outlet channel 121.

[0045] In the drying process, the wet and cold air entering the drying module 200 from the air outlet channel 121 in the process of circulating in the cylinder body 110 and the drying module 200 can carry the lint and other impurities in the clothes. In order to avoid the impurities entering the drying module 200, a filtering structure can be arranged in the air outlet channel 121 to filter the impurities in the wet and cold air. After the drum 100 works for a period of time, some impurities can be attached to the filtering structure, and if the impurities are attached too much, the amount of wet and cold air entering the drying module 200 will be affected, and then the drying speed will be affected. The filtering structure arranged in the air outlet channel 121 can be washed in the drying process, and the drainage channel 130 is arranged outside the cylinder body 110, so that the water and impurities for washing the filtering structure can be directly discharged through the drainage channel 130. That is, the water and impurities for washing the filtering structure basically will not flow into the cylinder body 110, thereby reducing the risk of secondary pollution of the clothes in the cylinder body 110 by the water and impurities for washing the filtering structure in the drying process, and improving the cleaning and drying effect of the clothes.

[0046] In the drying process, condensate water can be generated in the drying module 200, and the condensate water can also be directly discharged to the cylinder body 110 through the air outlet channel 121 and the drainage channel 130, which can also reduce the situation that the condensate water backflows and wets the clothes in the process of discharging the condensate water, and improve the drying effect of the clothes.

[0047] In some embodiments, the drain passage 130 is located below the drum 110. The drum 110 is substantially cylindrical, and in the working state, the axis of the drum 110 is substantially horizontally arranged. The overall shape of the entire clothes treatment device 10 is substantially cuboid, and the drain passage 130 is located below the drum 110, so that the drain passage 130 is arranged in the space below the columnar drum 110 by using the gap between the drum 110 and the shell of the clothes treatment device 10. The arrangement space of the drain passage 130 can be saved, and the entire clothes treatment device 10 can be more compact.

[0048] In some embodiments, the drain passage 130 is arranged separately from the drum 110. That is, the drain passage 130 and the drum 110 can be separate structures, and the drain passage 130 is connected to the air outlet passage 121. This arrangement is simple to operate and facilitates the assembly of the drain passage 130 and the air outlet passage 121.

[0049] In some other embodiments, the drain passage 130 can be mounted on the drum 110, and the outer surface of the drum 110 is configured as part of the inner wall of the drain passage 130. In this case, the outer surface of the drum 110 can be considered as part of the inner wall of the drain passage 130. With this arrangement, the drain passage 130 is directly mounted on the drum 110, and there is no gap between the drain passage 130 and the drum 110, so that the entire drum 100 structure can be more compact.

[0050] In these embodiments, the drain passage 130 can also be integrally formed with the outer drum 114. Integrally formed arrangement can reduce the mounting steps of the drain passage 130 and the outer drum 114, and the drain passage 130 can be directly connected to the air outlet passage 121 of the cover 120.

[0051] Please refer to Figure 4 , Figure 4 A structural schematic view of another perspective of the drum 100 is shown. As shown in Figure 2 and Figure 4 , the cover 120 includes a cover plate 124 and a connecting pipe 126. The cover plate 124 is mounted on the drum 110 and cooperates with the drum 110 to form the air outlet passage 121. The connecting pipe 126 connects the cover plate 124 and the water outlet pipe, and the connecting pipe 126 has a connecting passage 126a therein which connects the air outlet passage 121 and the drain passage 130.

[0052] Since the drain passage 130 is arranged outside the drum 110, the cover plate 124 is mounted on the drum 110, and the connecting pipe 126 serves to connect the cover plate 124 and the drain passage 130. The cover plate 124 is also substantially flat, so that the width of the cover plate 124 is relatively wide, while the pipe diameter of the drain passage 130 is relatively small. The connecting pipe 126 can serve to transitionally connect the cover plate 124 and the drain passage 130.

[0053] In addition, the drain passage 130 is arranged outside the drum body 110, the cover plate 124 is integrally formed with the drum body 110 to form the air outlet passage 121, and the connecting pipe 126 is integrally formed to form the connecting passage 126a.

[0054] Referring to Figure 5 , Figure 5 A structure diagram of the joint 140 is shown. The drum 100 further comprises the joint 140, which has a first interface 141, a second interface 142 and a third interface 143 in communication with each other. The first interface 141 is in communication with the water outlet of the drum body 110, the second interface 142 is in communication with the drain passage 130, and the third interface 143 is used to communicate with the drain pump.

[0055] The joint 140 has three interfaces, which can be communicated through a three-way joint. The water outlet of the drum body 110, the drain passage 130 and the drain pump do not need to be connected with the drain pump through another joint 140, and the number of components is not increased, and the connection of the drain passage 130 is facilitated.

[0056] Referring to Figure 6 , Figure 6 To Figure 2 A local enlarged view at I. In the case of flushing the filter structure or draining the condensed water, the water is also discharged through the air outlet passage 121. Since the air outlet 112c is in communication with the air outlet passage 121, the water may still flow back to the drum body 110 through the air outlet 112c. The baffle 150 arranged at the air outlet 112c can shield the air outlet 112c to a certain extent. In the case that the water flows to the air outlet 112c, the baffle 150 can block the water to a certain extent, thereby reducing the possibility of the water flowing back to the drum body 110 and reducing the possibility of the clothes being wet during the drying process, and improving the drying effect of the clothes.

[0057] As for the installation position of the baffle 150, the baffle 150 can be installed on the cover body 120 or the drum body 110. If the baffle 150 is installed on the drum body 110 (specifically on the outer drum 114), the shape of the baffle 150 can be adapted to the shape of the air outlet 112c. That is, the shape of the baffle 150 can be adapted to the edge shape of the air outlet 112c, and the baffle 150 can be arranged along the edge of the air outlet 112c, thereby being able to block the water from flowing back to the drum body 110, reducing the possibility of the clothes in the drum body 110 being wet during the drying process, and reducing the secondary pollution of lint and other impurities to the clothes.

[0058] Specifically, the baffle 150 can be located at least at the lowest point of the air outlet 112c. Since the air outlet 112c is arranged on the bottom surface 112b of the outer cylinder 114 and is arranged substantially vertically, the lowest point of the air outlet 112c is substantially the lowest position of the air outlet 112c, and is also the position where water is most likely to backflow. The baffle 150 is arranged at the lowest point of the air outlet 112c to avoid water backflowing from the air outlet 112c into the cylinder body 110 as much as possible, so as to reduce the risk of clothes being wetted by condensed water or cleaning water during drying.

[0059] The working principle of the drum 100 provided by the embodiment of the present application is as follows: in the drying mode, the wet and cold air in the cylinder body 110 can enter the drying module 200 through the air outlet passage 121, the dry and hot air after being dehumidified and heated by the drying module 200 enters the cylinder body 110 again to exchange heat with the air in the cylinder body 110, and the wet and cold air enters the drying module 200 again through the air outlet passage 121, so as to realize the circulation and dry the clothes in the cylinder body 110. If it is necessary to flush the filter structure or drain the condensed water, the water will flow from above the cover body 120 into the drain passage 130 through the air outlet passage 121 and be drained from the drain passage 130, so that the cleaning water for flushing the filter structure or the condensed water is not drained through the cylinder body 110, which can reduce the risk of clothes being wetted during drying and improve the drying effect.

[0060] Based on the same inventive concept, the embodiment of the present application also provides a clothes treatment device 10. The clothes treatment device 10 provided by the embodiment of the present application can reduce the risk of clothes being wetted during drying and improve the drying effect.

[0061] The clothes treatment device 10 comprises the drying module 200 and the drum 100 described above, and the air outlet passage 121 is in communication with the drying module 200. The drying module 200 can be mounted on the top of the drum 100. The specific structure of the drum 100 has been described in detail above, and will not be described here again.

[0062] In the description of the present specification, the description of the terms “one embodiment”, “some embodiments”, “an example”, “a specific example”, or “some examples” means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in the present specification.

[0063] In addition, the technical solutions among various embodiments can be combined with each other, but it must be based on that a person skilled in the art can realize, when the combination of technical solutions appears contradictory or cannot be realized, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the present application.

[0064] Although the embodiments of the present application have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and purposes of the present application, the scope of the present application is defined by the claims and their equivalents.
