[0040] To make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0041] The following describes in detail an assembly structure and an assembly method of a shell and a drum washing machine having the same according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0042] Example 1

[0043] This embodiment provides an assembly structure of a housing, such as Figure 1-Figure 13 As shown, it includes a front shell 100, a rear shell 200, a frame 300 and a base 400, the front shell 100 and the rear shell 200 cooperate to form a first accommodating cavity, the frame 300 and the base 400 are arranged in the first accommodating cavity, the frame 300 and the base 400 cooperate to form a second accommodating cavity, the second accommodating cavity is used to accommodate a drum assembly supporting the washing machine, the front shell 100 is fixedly connected to at least the frame 300 and the base 400, and the connection structure between the front shell 100 and the frame 300 is covered by the rear shell 200, the rear shell 200 is snap-connected to the front shell 100 from the inside, or the rear shell 200 is snap-connected to the front shell 100 from the inside, and the rear shell 200 is fixedly connected to the frame 300 and / or the base 400.

[0044] The inner side refers to the side of the front shell 100 and the rear shell 200 close to the first accommodating cavity. The front shell 100 and the rear shell 200 are arranged in an arc shape or eggshell shape as a whole. This arrangement makes the appearance of the washing machine arc-shaped, with beautiful lines, neat appearance, compact structure, and no edges and corners in the whole machine, which can avoid stress concentration and ensure the service life of the shell. Through the above arrangement, the front shell 100 is fixedly connected to the frame 300 and the base 400 respectively, and the rear shell 200 is connected to the front shell 100 by snap-fitting, which ensures the connection strength of the shell as a whole. In this case, when the washing machine is placed horizontally on a countertop or the ground, no screws or structural parts can be seen from the front side of the washing machine, and no screws can be seen throughout the washing machine, or only one screw on the rear shell 200 can be seen, which significantly improves the appearance of the washing machine.

[0045] As one of the preferred embodiments, a first positioning structure is provided between the front housing 100 and the frame 300 and / or the base 400. Since the front housing 100 is fixedly connected to the frame 300 and the base 400, respectively, corresponding fixing structures are provided between the front housing 100 and the frame 300, and between the front housing 100 and the base 400, respectively. By providing the first positioning structure between the front housing 100 and the frame 300 and / or the base 400, the corresponding fixing structure can be positioned. For example, when there is a corresponding screw connection structure, there is no need to consider the alignment problem. The first positioning structure can be automatically aligned by coordinating the positioning, which is simple and quick.

[0046] Specifically, Figure 4 , Figure 7As shown, the first positioning structure includes a second plug-in portion 140 and a plug-in hole 410, wherein the second plug-in portion 140 is disposed at a position near the lower end of the inner side of the front housing 100, and the plug-in hole 410 is correspondingly disposed on the base 400, and the second plug-in portion 140 cooperates with the plug-in hole 410 to limit the position. The second plug-in portion 140 may also be disposed at a position near the upper end of the front housing 100, and in this case, the plug-in hole 410 needs to be correspondingly disposed on the frame 300. It should be noted that when assembling the washing machine, the drum assembly is assembled first, and then the frame 300 and the base 400 are assembled together. After the assembly is completed, the frame 300 and the base 400 are covered on the outside of the drum assembly. At this time, the shell assembly can be carried out. Since the relative position between the frame 300 and the base 400 is fixed, the front shell 100 can be synchronously positioned with the frame 300 and the base 400 by coordinating and positioning with any one of the frame 300 and the base 400, thereby reducing the setting of the first positioning structure and simplifying the parts structure. It should be noted that the second plug-in portion 140 is preferably arranged at a position close to the lower end of the front shell 100. This is because, Figure 7 As shown, the lower end of the front shell 100 is an open structure, which is easily deformed during assembly, resulting in inaccurate positioning of the fixed structure. Providing a corresponding first positioning structure near the lower end can limit the deformation of the lower end of the front shell 100 during assembly, thereby ensuring the accuracy of the positioning of the fixed structure.

[0047] Better, such as Fig.10 As shown, the second plug-in portion 140 includes a second plug-in board 141, a second plug-in support board 142 and a third rib 143. The second plug-in support board 142 is fixedly arranged on the inner wall of the front housing 100. The second plug-in board 141 is arranged on the second plug-in support board 142, and the second plug-in board 141 extends to the rear side for mating with the plug-in hole 410. The third rib 143 is respectively connected to the inner wall of the front housing 100 of the second plug-in support board 142 to increase the strength of the second plug-in portion 140. Through the above arrangement, during assembly, the front housing 100 is pushed from front to rear, so that the second plug-in board 141 can enter the plug-in hole 410, which is simple and convenient.

[0048] As one example, Figure 2 , Figure 4 , Figure 7As shown, a plurality of first connecting parts 120 are arranged at a position near the rear end of the inner side of the front housing 100, and a plurality of fourth fixing parts 310 are correspondingly arranged on the frame 300, and the first connecting parts 120 and the fourth fixing parts 310 are matched and fixedly connected. The first connecting parts 120 are used to realize the fixed connection between the front housing 100 and the frame 300 to strengthen the strength of the front housing 100, and due to the setting of the first positioning structure, when the front housing 100 is assembled, the first connecting parts 120 and the fourth fixing parts 310 can be automatically aligned and positioned, which significantly improves the assembly efficiency of the front housing 100.

[0049] Specifically, Figure 8As shown, the first connection part 120 includes a screw fixing platform 121, a fixing platform support plate 122 and a first rib plate 123. The fixing platform support plate 122 is fixedly arranged on the inner wall of the front housing 100. The screw fixing platform 121 is fixedly arranged on the fixing platform support plate 122. The screw fixing platform 121 is used to be fixedly connected with the fourth fixing part 310. The first rib plate 123 is respectively connected with the fixing platform support plate 122 and the inner wall of the front housing 100, and is used to increase the strength of the first connection part 120. Specifically, corresponding screw holes are respectively arranged on the screw fixing platform 121 and the fourth fixing part 310. When the screws are assembled, they are fixedly connected with the screw fixing platform 121 after passing through the fourth fixing part 310, so as to realize the matched fixed connection between the front housing 100 and the frame 300. In addition, the setting of the first positioning structure enables the screw holes on the screw fixing platform 121 and the fourth fixing part 310 to be automatically aligned, which significantly improves the assembly efficiency. It should be noted that the screw fixing platform 121 is extended in the front-to-back direction, and the rear end of the screw fixing platform 121 partially extends out of the front shell 100. Since the front shell 100 is arranged in an arc shape as a whole, its inner wall does not have a plane, and the screw fixing platform 121 extending forward and backward cannot be directly arranged. The fixing platform support plate 122 provides a corresponding setting plane for the screw fixing platform 121, and the first rib plate 123 provides a reinforcing support for the fixing platform support plate 122, thereby improving the overall strength of the first connecting portion 120, thereby ensuring the connection strength after the front shell 100 is fixedly connected to the frame 300. Optionally, the frame 300 is a metal part, and the fourth fixing portion 310 is a metal plate stamped on the frame 300. This setting can simplify the production steps of the frame 300, reduce the corresponding parts setting, and improve production efficiency on the basis of ensuring the connection strength after the front shell 100 is fixedly connected to the frame 300. The rear end of the first rib plate 123 is connected to the fixed platform support plate 122, and the front end thereof extends forward, and the height thereof gradually decreases. This arrangement can enhance the overall strength of the rear end of the front housing 100 while enhancing the strength of the first connecting portion 120, thereby improving the overall strength of the washing machine housing. More than one first rib plate 123 can be provided, such as two or three. When more than two first rib plates 123 are provided, the first rib plates 123 can be the same or different. In addition, the first rib plates 123 in different first connecting portions 120 can be the same or different.

[0050] As one example, Figure 5 , Figure 7As shown, a plurality of first fixing parts 150 are provided at a position near the lower end of the inner side of the front housing 100, and a plurality of sixth fixing parts 420 are correspondingly provided on the base 400, and the first fixing parts 150 cooperate with the sixth fixing parts 420 to be fixedly connected. The first fixing parts 150 cooperate with the sixth fixing parts 420 to fix the front housing 100 and the base 400, and due to the provision of the first positioning structure, the first fixing parts 150 and the sixth fixing parts 420 are automatically aligned during assembly, thereby improving assembly efficiency.

[0051] Specifically, Fig.10 As shown, the first fixing portion 150 includes a first fixing plate 151, a first supporting plate 152 and a convex strip 153, the first fixing plate 151 is used to cooperate with the sixth fixing portion 420 for connection, the first fixing plate 151 is fixedly disposed on the inner wall of the front shell 100, and the first fixing plate 151 is horizontally disposed, the first supporting plate 152 is disposed on the lower side of the first fixing plate 151, the first supporting plate 152 is respectively connected to the inner wall of the front shell 100 and the first fixing plate 151, and is used to support the first fixing plate 151, and a convex strip 153 is disposed on the upper side of the first fixing plate 151. The two ends of the convex strip 153 are provided with guide slopes. The convex strip 153 is used to achieve the line fit between the first fixing plate 151 and the sixth fixing part 420 during the matching assembly. Since the matching surfaces of the first fixing plate 151 and the sixth fixing part 420 are both planes, the two are easily interfered by the processing error during the front-to-back pushing and matching process, resulting in the inability to assemble. The setting of the convex strip 153 makes the matching between the first fixing plate 151 and the sixth fixing part 420 form a line-surface match, which is conducive to the relative translational push of the two. In addition, when there is a processing error, since the front housing 100 is an injection molded part, it has a certain deformation ability. The corresponding translational fit between the first fixing plate 151 and the sixth fixing part 420 can still be achieved through the guide structure at the end of the convex strip 153, so as to achieve the smooth matching assembly of the front housing 100 and the base 400. In one embodiment, corresponding screw holes are respectively provided on the first fixing plate 151 and the sixth fixing part 420. During assembly, the screws pass through the first fixing plate 151 from bottom to top and are fixedly connected with the sixth fixing part 420.

[0052] As an embodiment of the present invention, Figure 3As shown, a plurality of snap-in structures are arranged between the front housing 100 and the rear housing 200, and the snap-in structures include a first plug-in portion 130 and a first snap-in portion 210, and the first plug-in portion 130 is snap-in-matched with the first snap-in portion 210. After the front housing 100 is fixedly connected to the frame 300 and the base 400, the rear housing 200 can be installed by snapping with the front housing 100, which is simple and convenient, and improves the assembly efficiency. Among them, the first plug-in portion 130 is arranged on the inner side wall of the front housing 100 and / or the rear housing 200, and the first snap-in portion 210 is correspondingly arranged on the inner side wall of the rear housing 200 and / or the front housing 100. Among them, when the first plug-in portion 130 is arranged on the front housing 100, it at least partially extends out of the rear end of the front housing 100.

[0053] Specifically, Fig. 9 , Fig.11 , Fig.12 As shown, the first plug-in portion 130 includes a first plug-in board 131, a hook 132, a first plug-in support plate 133, and a second rib plate 134. The first plug-in support plate 133 is fixedly arranged on the inner wall of the front shell 100 and / or the rear shell 200. The first plug-in board 131 is arranged on the first plug-in support plate 133. The second rib plate 134 is arranged on the first plug-in support plate 133 at a side away from the first plug-in board 131, and is used to strengthen the strength of the first plug-in support plate 133. A hook 132 is arranged at one end of the first plug-in board 131 away from the first plug-in support plate 133, and the hook 132 is used to cooperate with the first clamping portion 210 for clamping; the first clamping The connection part 210 includes a first support plate 211, a limit plate 212, a clamping hole 213, a clamping support plate 214, and a fourth rib plate 215. The clamping support plate 214 is fixedly arranged on the inner wall of the rear housing 200 and / or the front housing 100. The first support plate 211 is arranged on the clamping support plate 214. The fourth rib plate 215 is arranged on the side of the clamping support plate 214 away from the first support plate 211, and is used to strengthen the strength of the clamping support plate 214. The limit plates 212 are arranged on both sides of the first support plate 211, and the clamping hole 213 is arranged at the position of the first support plate 211 close to the clamping support plate 214. The clamping hole 213 is used to engage with the hook 132. The limit plate 212 is used to limit the position of the first plug-in board 131 when it is engaged. Through the above arrangement, when the front shell 100 and the rear shell 200 are assembled, the first plug-in board 131 is inserted into the space defined by the first support plate 211 and the limiting plate 212, and then the front shell 100 is pushed backward, and / or the rear shell 200 is pushed forward, so that the hook 132 is engaged with the hole 213, and the assembly of the rear shell 200 is completed. The assembly process is simple and convenient.

[0054] As one of the preferred embodiments, a second positioning structure is provided between the rear housing 200 and the frame 300 and / or the base 400. The second positioning structure is provided to assist the alignment of the first plug-in portion 130 and the first clamping portion 210, thereby improving the assembly efficiency of the product.

[0055] Specifically, Figure 4 , Fig.11 As shown, the second positioning structure includes a third plug-in portion 220 and a plug-in hole 410. The third plug-in portion 220 is arranged on the rear housing 200, and the plug-in hole 410 is correspondingly arranged on the base 400. The specific structure of the third plug-in portion 220 can refer to the second plug-in portion 140, and it can also be arranged at a position close to the upper end and / or the lower end of the rear housing 200. The difference is that the plug-in direction of the third plug-in portion 220 is from back to front.

[0056] As an optional embodiment, Figure 5 , Fig.11 As shown, a plurality of second fixing parts 230 are arranged at a position near the lower end of the inner side of the rear shell 200, and a plurality of sixth fixing parts 420 are correspondingly arranged on the base 400, and the second fixing parts 230 and the sixth fixing parts 420 cooperate to be fixedly connected. The second fixing parts 230 and the sixth fixing parts 420 cooperate to fix the front shell 100 and the rear shell 200. Due to the setting of the second positioning structure, the second fixing parts 230 and the sixth fixing parts 420 are automatically aligned during assembly, thereby improving assembly efficiency. It should be noted that the number of the sixth fixing parts 420 is equal to the sum of the number of the first fixing parts 150 and the second fixing parts 230, so as to realize the corresponding fixed connection between the base 400 and the front shell 100 and the rear shell 200.

[0057] As one of the preferred embodiments, Figure 4 , Fig.13As shown, a third fixing portion 250 is provided on the rear housing 200, and a fifth fixing portion 320 is correspondingly provided on the frame 300, and the third fixing portion 250 and the fifth fixing portion 320 are fixedly connected in cooperation. Specifically, the third fixing portion 250 is a sinking structure, a screw hole is provided on the sinking structure, and a corresponding screw hole is provided on the fifth fixing portion 320. During assembly, the screw passes through the rear housing 200 and is fixedly connected to the fifth fixing portion 320. This setting can realize the fixed connection between the rear housing 200 and the frame 300, and further improve the installation reliability of the rear housing 200. The third fixing portion 250 and the fifth fixing portion 320 are provided, and a screw can be observed from the rear side of the washing machine, which has a certain impact on the appearance of the washing machine. The setting of the sinking structure can reduce the probability of users seeing the screws and improve the user experience. It should be noted that the second fixing portion 230 and its corresponding sixth fixing portion 420, third fixing portion 250 and fifth fixing portion 320 can be set according to actual conditions. In some models, since the structure on the rear side of the washing machine is relatively compact, only the third fixing portion 250 and the fifth fixing portion 320 can be set, or the second fixing portion 230 and its corresponding sixth fixing portion 420, third fixing portion 250 and fifth fixing portion 320 may not be set, and the installation strength of the rear shell 200 can meet the relevant use requirements.

[0058] As one of the embodiments, the rear end of the front shell 100 is connected to the front end of the rear shell 200 through a concave-convex structure. In the prior art, if the two shell seams are connected by straight edges, there is a risk of water entering the gap at the connection. In this embodiment, the concave-convex structure can be a step-shaped structure. This setting makes the seam at the connection between the front shell 100 and the rear shell 200 form a staggered structure, avoiding the formation of a through gap, significantly improving the waterproof performance of the shell structure, and further improving the stability of the shell connection.

[0059] As one example, Figure 3 As shown, a concave platform 160 is provided at the rear end of the front housing 100, and a convex platform 240 is provided at the front end of the rear housing 200, and the concave platform 160 is provided in cooperation with the convex platform 240. It should be understood that the concave platform 160 can also be provided at the front end of the rear housing 200, and the convex platform 240 can be correspondingly provided at the rear end of the front housing 100, wherein the thickness of the concave platform 160 after cooperation with the convex platform 240 is equal to the thickness of the front housing 100 and the rear housing 200.

[0060] As a preferred embodiment, Figure 6As shown, a sink 110 is provided on the front side of the front shell body 100, and a clothing delivery port 113 is provided on the sink 110, and the clothing delivery port 113 is provided corresponding to the delivery port of the drum assembly. The sink 110 is also used to set the door body of the drum washing machine, and the door body is used to close or open the clothing delivery port 113. A detergent delivery port 111 is provided on the sink 110, and the detergent delivery port 111 is used to deliver detergent.

[0061] In the prior art, the detergent delivery structure of the drum washing machine is usually separately arranged on the front side of the drum washing machine and is not related to the door body. In the present application, when the door body closes the clothing delivery port 113, the detergent delivery port 111 is also blocked, and the detergent delivery structure cannot be seen from the outside. On the one hand, it avoids setting the detergent delivery structure in other areas outside the door body, making the structure of the drum washing machine more compact. On the other hand, only the door body can be seen on the front side of the drum washing machine as a whole, without other related structures, making the drum washing machine more beautiful and compact as a whole. The delivery of the detergent includes directly pouring the detergent, and also includes setting the detergent delivery box containing the detergent inside the detergent delivery port 111. In this embodiment, when the door body closes the clothing inlet 113, the door body is at least partially disposed in the recessed area formed by the sink 110, and a door glass is disposed on the door body. When the door body closes the clothing inlet 113, the door glass passes through the clothing inlet 113 and cooperates with the sealing component on the outer drum assembly to seal. For the cooperation and sealing between the door glass and the sealing component, reference can be made to the specific contents of the drum washing machine in the prior art, which will not be repeated here. Preferably, the detergent inlet 111 is disposed at a position close to the lower side of the sink 110. This position has a larger space, which is convenient for users to perform corresponding operations.

[0062] As an embodiment of the present invention, a cover plate (not shown in the drawings) is provided on the detergent inlet 111, and the cover plate is used to close or open the detergent inlet 111. The provision of the cover plate enables the sink 110 to form a relatively complete structure, and the detergent inlet 111 cannot be seen when the door is opened, which improves the overall aesthetics of the drum washing machine on the one hand, and prevents clothes from falling into the detergent inlet 111 when taking clothes out, which may affect the detergent or clothes.

[0063] As one of the preferred embodiments, Figure 1 , Figure 6As shown, the sink 110 is arranged in an upward tilt from front to back. This arrangement enables the door body to be arranged in an upward tilt from front to back. In the prior art, the door body of a drum washing machine is usually arranged vertically at the front side. When operating, the user needs to squat or bend down nearly 90 degrees to operate, which is inconvenient to take and put clothes, and it is also not easy to observe the clothes in the drum washing machine. In this embodiment, through the inclined arrangement of the sink 110 and the door body, the user only needs to bend down slightly to open or close the door body of the drum washing machine, and it is more convenient to put in or take out clothes. It also allows the user to observe the clothes inside the drum washing machine, which significantly improves the user experience.

[0064] As a preferred embodiment, the front housing 100 is integrally injection molded. The sink 110, detergent inlet 111, clothing inlet 113, first connecting portion 120, first plug-in portion 130, second plug-in portion 140, first fixing portion 150, recessed platform 160 and other structures are integrally molded by injection molding. This arrangement only requires one mold to produce multiple connecting parts while producing the front housing 100, which greatly reduces the number of parts and improves production efficiency.

[0065] As another preferred embodiment, the rear housing 200 is integrally injection molded. The first clamping portion 210, the third plugging portion 220, the second fixing portion 230, the boss 240, the third fixing portion 250 and other structures are integrally injection molded. This arrangement only requires one mold to produce multiple connecting parts while producing the rear housing 200, which greatly reduces the number of parts and improves production efficiency.
