[0036] like Figure 1-6As shown, the present invention provides a washing machine door structure, including a door body 1, wherein the door body 1 includes an inner frame 12 and an outer frame 11, the inner frame 12 and the outer frame 11 are interlocked with each other so that the interior of the door body 1 is hollow to form a closed cavity, and an assembly gap 13 communicating with the cavity is formed at the contact position between the inner frame 12 and the outer frame 11, and a sealing structure 2 for sealing the assembly gap 13 is provided on the door body 1.

[0037] In the embodiment of the present invention, by providing a sealing structure 2 on the door body 1, the sealing structure 2 can seal the assembly gap 13 connecting the inside and outside of the door body 1, preventing the washing water outside the door body 1 from entering the inside of the door body 1 through the assembly gap 13, thereby protecting the electrical components inside the door body 1 from being corroded by the washing water, and improving the service life of the electrical components inside the door body 1; the electrical components can be a fan for taking air into the drum, a delivery box for delivering detergent into the drum, etc.;

[0038] The door body 1 structure is suitable for a drum washing machine, which includes a casing and an outer drum and an inner drum arranged in the casing, wherein the inner drum is rotatably arranged in the outer drum; the door body 1 in the door body 1 structure may be an inner drum door rotatably arranged on the inner drum to open and close the inner drum opening, or the door body 1 in the door body 1 structure may also be a door rotatably arranged on the casing to open and close the clothing inlet provided on the casing for putting clothes into the inner drum; it should be noted that when the inner drum is provided with an inner drum door, the inner drum is a drum without holes, and the inner drum is a water storage drum;

[0039] like Fig.10 As shown, when the door body 1 in the door body 1 structure is a machine door, the machine casing is provided with a front panel 14, and a clothing inlet 141 is provided on the front panel 14. The machine door can be rotatably mounted on the front panel 14, and when the machine door is closed, it covers the front panel 14 and the clothing inlet 141 accordingly; the machine door covers the front panel 14 and the clothing inlet 141, so that the appearance of the drum washing machine is smoother and smoother, which not only improves the beauty of the product, but also facilitates the user to wipe and clean it, and the machine door forms a protection for the front panel and the clothing inlet, preventing dust from entering the interior of the drum washing machine from the clothing inlet, and preventing dust from accumulating on the front panel and the clothing inlet, thereby improving the cleanliness and hygiene of the product and improving the user's experience.

[0040] It should be noted that the inside and outside mentioned below refer to the side of the door body 1 facing the outer tube and the inner tube when the door body 1 is closed, and the side facing away from the outer tube and the inner tube is the outside.

[0041] like Figure 2 , Figure 3 and Figure 4As shown, in an embodiment of the present invention, the sealing structure 2 is a sealing strip 21, and the outer periphery of the inner frame 12 and the outer periphery of the outer frame 11 are bent toward each other to form an inner frame flange 121 and an outer frame flange 111, respectively. The inner frame flange 121 and the outer frame flange 111 are interlocked with each other, and an assembly gap 13 is formed at the contact position between the two. The inner and outer ends of the assembly gap 13 are respectively provided with an inner port and an outer port. The assembly gap 13 is connected with the outside of the door body 1 via the inner port or the outer port, and the sealing strip 21 is provided at the inner port or the outer port of the assembly gap 13, and extends along the circumference of the assembly gap 13.

[0042] In an embodiment of the present invention, the inner frame 12 and the outer frame 11 are flat-plate structures, and the inner frame flange 121 and the outer frame flange 111 make the inner frame 12 and the outer frame 11 in a groove shape. When buckled together, the notch of the outer frame 11 faces the inner frame 12, and the notch of the inner frame 12 faces the outer frame 11, so that a closed cavity can be formed inside the door body 1 after the outer frame 11 and the inner frame 12 are buckled together.

[0043] The assembly gap 13 extends along the circumferential direction of the inner frame flange 121 and the outer frame flange 111, so that the assembly gap 13 has an inner end located at the inner end of the door body 1 and an outer end located at the outer end of the door body 1;

[0044] When the inner frame flange 121 is buckled onto the outer frame flange 111, the inner port of the assembly gap 13 is located inside the door body 1, and the assembly gap 13 is connected to the outside of the door body 1 through the outer port. The outer port of the assembly gap 13 is sealed by the sealing strip 21, so that the outside and the inside of the door body 1 are not connected.

[0045] When the outer frame flange 111 is buckled onto the outer side of the inner frame flange 121, the outer port of the assembly gap 13 is located inside the door body 1, and the assembly gap 13 is connected to the outside of the door body 1 through the inner port. The assembly gap 13 is sealed by sealing the inner port of the assembly gap 13 with the sealing strip 21.

[0046] The assembly gap 13 can be formed at any position of the door body 1 in the circumferential direction, and the assembly gap 13 can be continuous or intermittent.

[0047] Furthermore, the inner frame flange 121 is formed by bending the outer periphery of the inner frame 12 along the axial direction of the door body 1, and the outer frame flange 111 is formed by bending the outer periphery of the outer frame 11 along the axial direction of the door body 1. The position where the outer end of the inner frame flange 121 and the inner end of the outer frame flange 111 contact each other forms an assembly gap 13, so that the assembly gap 13 extends in a straight line along the axial direction of the door body 1, thereby avoiding residual water in the assembly gap 13.

[0048] Specifically, the door body 1 is square, the inner frame flange 121 and the outer frame flange 111 are arranged at the top of the door body 1, and extend from one side to the other side in the width direction of the door body 1, the inner frame flange 121 is buckled into the upper part of the outer frame flange 111, and the position where the bottom surface of the inner frame flange 121 contacts the top surface of the outer frame flange 111 forms an assembly gap 13, and the sealing strip 21 is arranged at the outer end of the assembly gap 13, and the assembly gap 13 and the sealing strip 21 extend from one side to the other side in the width direction of the door body 1.

[0049] The door body 1 is square, the thickness direction of the door body 1 is the axial direction of the door body 1, the width direction of the door body 1 is the radial direction of the door body 1, the assembly gap 13 is formed at the top of the door body 1, and the sealing strip 21 has the same extension trajectory as the assembly gap 13 to achieve maximum sealing of the assembly gap 13.

[0050] The assembly gap 13 is formed at the top of the door body 1 , and can prevent wash water from entering the inside of the door body 1 from the top of the door body 1 .

[0051] like Figure 1-6 As shown, in an embodiment of the present invention, the door body 1 structure also includes a decorative strip 3 for blocking the assembly gap 13, and the decorative strip 3 includes a blocking portion 31 that extends from the top surface of the inner frame flange 121 and extends to the top of the outer frame flange 111, and a guide groove 4 with a notch facing the inner frame flange 121 is formed between the bottom surface of the blocking portion 31 and the top surface of the outer frame flange 111, and the sealing strip 21 is inserted into the guide groove 4, and the outer end of the inner frame flange 121 is inserted into the guide groove 4 through the notch, and the end face 1211 of the outer end of the inner frame flange cooperates with the inner side surface of the bottom of the guide groove 4 to extrude the sealing strip 21.

[0052] In the embodiment of the present invention, the decorative strip 3 is used to cover the assembly gap 13, so that the door body 1 has a more beautiful appearance;

[0053] The shielding portion 31 extends from the inner side end of the inner frame flange 121 to the top surface of the inner frame flange 121, passes through the top of the outer frame flange 111, and extends to the outer side end of the outer frame flange 111. The outer side end of the inner frame flange 121 and the inner side end of the outer frame flange 111 are in contact with each other to form an assembly gap 13, so that a certain space is formed between the shielding portion 31 and the outer frame flange 111 that is not in contact with the inner frame flange 121; a guide groove 4 is formed in the space, and the sealing strip 21 is inserted into the guide groove 4 to stabilize the sealing strip 21, and guide the end surface 1211 of the outer side end of the inner frame flange to prevent the sealing strip 21 from being misaligned, thereby improving the sealing performance of the sealing strip 21;

[0054] Specifically, the outer end of the inner frame flange 121 is inserted into the guide groove 4 through the notch, so that the assembly gap 13 formed by the inner frame flange 121 and the outer frame flange 111 is located at the bottom of the guide groove 4, and the end face 1211 of the outer end of the inner frame flange cooperates with the inner side face of the bottom of the guide groove 4 along the axial direction of the door body 1 to extrude the sealing strip 21, so that the sealing strip 21 is extruded and deformed in the axial direction of the door body 1 to form a sealing area, which is higher than the height of the assembly gap 13. The sealing area blocks the washing water from flowing into the bottom of the guide groove 4 and contacts the outer port of the assembly gap 13.

[0055] like Figure 2 , Figure 3 and Figure 4 As shown, further, an extrusion protrusion 311 is provided on the bottom surface of the shielding portion 31, and the extrusion protrusion 311 extends toward the outer frame 11 and extends to abut against the top surface of the outer frame flange 111. The extrusion protrusion 311 and the outer frame flange 111 are vertically arranged, and the extrusion protrusion 311, the shielding portion 31 and the outer frame flange 111 form a guide groove 4, and the end face 1211 of the outer end of the inner frame flange cooperates with the inner side face of the extrusion protrusion 311 to extrude the sealing strip 21.

[0056] The decorative strip 3 includes a shielding portion 31 and an auxiliary shielding portion 32 formed by bending the outer end of the shielding portion 31 downward, the auxiliary shielding portion 32 gradually extends from top to bottom toward the outside of the door body 1, and the auxiliary shielding portion 32 further shields the assembly gap 13. The inclined setting of the auxiliary shielding portion 32 can make the washing water on the top of the door body 1 flow downward along the auxiliary shielding portion 32, flow outside the door body 1, and not flow into the door body 1.

[0057] The top of the outer frame 11 is bent to form an inclined portion 113, which gradually extends from top to bottom toward the outside of the door body 1. The auxiliary shielding portion 32 covers the upper portion of the inclined portion 113 in the same inclination direction as the inclined portion 113. The upper portion of the auxiliary shielding portion 32 is provided with information about the model of the drum washing machine, etc., which conforms to the viewing angle of the user.

[0058] like Figure 4 As shown, as a preferred solution, the size of the outer end of the inner frame flange 121 gradually decreases from the inner side to the outer side of the door body 1, and the end surface of the outer end of the inner frame flange 121 with the smallest size cooperates with the inner side surface of the extrusion protrusion 311 to extrude the sealing strip 21. The end surface of the outer end of the inner frame flange 121 with the smallest size is used to extrude the sealing strip 21, which can increase the extrusion force on the sealing strip 21 and increase the sealing strength of the sealing strip 21.

[0059] For example, the inner frame flange 121 is square, and the inner frame flange 121 has a top surface and a bottom surface, a front side surface located at the outer end of the door body 1, and a rear side surface located at the inner end of the door body 1 and connected to the inner frame 12, wherein the front side surface of the inner frame flange 121 is the end surface with the smallest size at the outer end of the inner frame flange 121.

[0060] like Figure 4 As shown, further, the bottom surface of the shielding portion 31 and the inner side surface of the extrusion protrusion 311 are transitionally connected via an arc segment 41, and the arc segment 41 protrudes outward from the guide groove 4, providing a buffer space for the extrusion deformation of the sealing strip 21, thereby preventing the connection position between the bottom surface of the shielding portion 31 and the inner side surface of the extrusion protrusion 311 from hindering the extrusion of the sealing strip 21 and damaging the sealing strip 21.

[0061] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in an embodiment of the present invention, a hook groove 122 is provided at the bottom of the inner frame flange 121, and an upwardly bent hook portion 112 is provided at the inner end of the outer frame flange 111. The hook portion 112 is hooked in the hook groove 122 to provide extrusion force for the extruded sealing strip 21.

[0062] In the embodiment of the present invention, the hook groove 122 is arranged at the bottom of the inner frame flange 121, the notch of the hook groove 122 is arranged downward, there are multiple hook grooves 122, and the multiple hook grooves 122 are evenly distributed along the width direction of the door body 1;

[0063] A notch 114 is provided at the inner end of the outer frame flange 111, and a hook portion 112 is provided in the notch 114. The hook portion 112 includes a support portion and a hook portion. The support portion extends along the axial direction of the door body 1, and one end of the axially extending support portion is connected to the notch 114. The other axial end of the support portion is provided with a hook portion. There are gaps between the left and right sides of the axially extending support portion and the corresponding side walls of the notch 114, so that the support portion can be deformed to a certain extent, so that the hook portion can hook the hook groove 122 conveniently.

[0064] There are multiple notch portions 114, and the multiple notch portions 114 are evenly distributed along the width direction of the door body 1. A clamping hole 115 is provided between two adjacent notch portions 114. The clamping hole 115 includes a first section extending along the axial direction of the door and a second section extending along the radial direction of the door body 1. The second section is connected to the middle part of the first section.

[0065] like Fig. 9 As shown, a snap-fitting protrusion 312 is provided at the bottom of the extrusion protrusion, and the snap-fitting protrusion 312 includes a third section extending along the axial direction of the door body 1 and a fourth section extending along the radial direction of the door body 1. The third section is connected to the bottom of the extrusion protrusion through the fourth section, and the fourth section is connected to the middle of the third section. When snap-fitting, after the third section and the fourth section pass through the first section from top to bottom, the fourth section moves toward the second section and snaps into the second section. The outer frame flange 111 at the periphery of the snap-fitting hole 115 is clamped between the third section and the shielding portion 31 of the decorative strip 3, which guides the sliding snap-fitting of the fourth section, thereby accelerating the efficiency of installing the shielding portion 31 on the outer frame flange 111.

[0066] During installation, the decorative strip 3 is installed on the outer frame flange 111 by sliding the clamping protrusion into the clamping hole 115, and a guide groove 4 is formed between the outer frame flange 111, and the sealing strip 21 is clamped into the guide groove 4;

[0067] After the inner frame 12 is buckled onto the outer frame 11 , the end surface 1211 of the outer end of the inner frame flange cooperates with the inner side surface of the bottom of the guide groove 4 to squeeze the sealing strip 21 , so that the sealing strip 21 is deformed to form a sealing area.

[0068] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention.
