[0057] It should be noted that since the water inlet 4, the water outlet 5 and the water flow channel 6 are all integrally formed inside the door sealing ring 3, an integrally formed sprinkler head structure is formed. The sprinkler head structure does not require installation and has high reliability. It can effectively solve the problems of independent sprinkler heads being difficult to fix, easy to fall off, poorly sealed, and having the risk of water leakage, thereby improving and optimizing the performance of the door sealing ring 3.

[0058] See also Figures 7 and 8 As shown, in some embodiments, the water outlet 51 is disposed on the rear side wall of the water outlet portion 5, the water outlet 51 is exposed on the inner peripheral edge of the door seal ring 3, and the water outlet 51 faces the inside of the washing chamber 20. Therefore, the external water source can smoothly spray water toward the inside of the washing chamber 20 through the water outlet 51 on the rear wall of the water outlet portion 5, thereby realizing the functions of spraying and washing.

[0059] It should be noted that, in other embodiments, the water outlet 51 may also be disposed on the bottom side wall or other side walls of the water outlet portion 5 .

[0060] See also Figures 7 and 8 As shown, in some embodiments, the door seal ring 3 is provided with a plurality of integrally formed spray head structures, and the plurality of spray head structures are arranged at intervals on the door seal ring 3.

[0063] See also Figures 7 to 12 As shown, in some embodiments, the water outlet 5 and the water inlet 4 are arranged opposite to each other in the radial direction of the door seal ring 3, so that the water outlet 5 and the water inlet 4 can be located in the same diameter direction of the door seal ring 3 and arranged opposite to each other in the inner and outer directions. At the same time, the water flow channel 6 is arranged to extend along the radial direction of the door seal ring 3.

[0064] It should be noted that, in other embodiments, the water outlet 5 and the water inlet 4 are arranged in an inner and outer staggered manner in the radial direction of the door sealing ring 3 . In this case, the water flow channel 6 does not extend in the radial direction of the door sealing ring 3 .

[0065] See also Figures 4 to 12 As shown, in some embodiments, the door sealing ring 3 includes a first mounting portion 31 , a neck portion 32 , a stretching deformation portion 33 and a second mounting portion 34 which are sequentially connected front to back along the axial direction.

[0066] The first mounting portion 31 is located at the front end of the door sealing ring 3 , is annular, and is sealed to the peripheral edge of the clothing inlet 11 , that is, the front end of the first mounting portion 31 is connected to the front wall of the box body 1 .

[0067] The neck portion 32 is disposed on a side of the first mounting portion 31 away from the clothing loading port 11 , and is annular and extends along the axial direction of the door sealing ring 3 . The front end of the neck portion 32 is axially connected to the rear end of the first mounting portion 31 .

[0068] The stretching deformation part 33 is annular, and is arranged on a side of the neck 32 away from the first mounting part 31, the front end of the stretching deformation part 33 is axially connected to the rear end of the neck 32, and the stretching deformation part 33 can be extended and retracted in the axial and radial directions of the door seal ring 3. Therefore, when the drum washing machine is running, the drum assembly 2 vibrates, and the stretching deformation part 33 can be deformed in the axial and radial directions with the vibration of the drum assembly 2, so that the door seal ring 3 can maintain a sealed connection between the clothing loading port 11 of the box body 1 and the drum mouth of the outer drum 21.

[0069] See also Figures 4 to 12 As shown, in some embodiments, the water inlet 4 is convexly arranged on the outer peripheral wall of the stretching deformation part 33, the water outlet 5 is arranged on the inner side wall of the stretching deformation part 33, and the water flow channel 6 is formed in the stretching deformation part 33. Therefore, when the drum washing machine is running, the stretching deformation part 33 can be deformed in the axial direction and the radial direction with the vibration of the drum assembly 2, and at the same time, the water inlet 4 located on the stretching deformation part 33 can maintain a stable connection with the water inlet pipeline, so as to avoid the connection between the water inlet 4 and the water inlet pipeline being disconnected due to the vibration of the drum assembly 2.

[0070] See also Figures 4 to 12 As shown, in some embodiments, the stretching deformation portion 33 includes a radial extension portion 331 and an axial fixing portion 332. The radial extension portion 331 is provided at one end of the neck portion 32 away from the first mounting portion 31, and the radial extension portion 331 is extended from the neck portion 32 toward the outer circumference of the door seal ring 3, and the axial fixing portion 332 is bent and extended from the outer end of the radial extension portion 331 toward the direction of the second mounting portion 34, and the axial fixing portion 332 is axially connected to the second mounting portion 34. Therefore, when the barrel assembly 2 vibrates, the radial extension portion 331 and the axial fixing portion 332 can approach or move away from each other, so that the stretching deformation portion 33 can be deformed in the axial direction and in the radial direction.

[0071] In addition, it should be noted that the radial extending portion 331 itself can be deformed in the radial direction, and the axial fixing portion 332 itself can be deformed in the axial direction.

[0072] See also Figures 4 to 12 As shown, in some embodiments, the water inlet 4 is provided on the outer peripheral wall of the axial fixing portion 332, and the water outlet 5 is provided on the inner side wall of the axial fixing portion 332. The water inlet 4 and the water outlet 5 are integrally formed with the axial fixing portion 332, and the water outlet 5 and the water inlet 4 are arranged on the inner and outer sides of the axial fixing portion 332 in an inner and outer manner.

[0073] It should be noted that, in some other embodiments, the water inlet 4 and the water outlet 5 can also be integrally formed on the radial extension portion 331. In this case, the water outlet 5 and the water inlet 4 are arranged on the inner and outer sides of the radial extension portion 331 in an inner and outer manner.

[0074] See also Figure 11 to Figure 12 As shown, in some embodiments, the water outlet portion 5 is arranged in a region enclosed by the radially extending portion 331 , the axially fixing portion 332 and the second mounting portion 34 .

[0075] In some embodiments, the back of the water outlet 5 is axially connected to the second mounting portion 34, the inner end of the water outlet 5 protrudes out of the inner peripheral wall of the second mounting portion 34, and the water outlet 51 is located at the inner peripheral edge of the second mounting portion 34. Therefore, the water outlet 5 and the water outlet 51 can be fixed on the second mounting portion 34, so that the water outlet 51 can stably spray water into the washing chamber 20, so that the spray angle and spray range of the water outlet 51 can be kept consistent.

[0076] See also Figures 9 to 12 As shown, in some embodiments, a clearance gap (not shown in the figure) is formed between the water outlet 5 and the radial extension portion 331. Therefore, when the door seal ring 3 is deformed due to the vibration of the cylinder assembly 2, the clearance gap can prevent the water outlet 5 from directly contacting the radial extension portion 331, and prevent collision and friction between the water outlet 5 and the neck 32.

[0077] In some embodiments, a relief groove 333 is recessed in the radial extension portion 331 toward the neck 32, the water outlet 5 extends into the relief groove 333, and a relief gap is formed between the water outlet 5 and the groove wall of the relief groove 333. The relief groove 333 can be used to make way for the water outlet 5, thereby avoiding collision and friction between the water outlet 5 and the neck 32.

[0078] See also Figure 11 to Figure 12 As shown, in some embodiments, the water flow channel 6 includes an extension section 61 and a turning section 62 that are interconnected. The extension section 61 is arranged to extend inward along the radial direction of the door seal ring 3, the outer end of the extension section 61 is connected to the water inlet 41, and the inner end of the extension section 61 is connected to the turning section 62. The turning section 62 is extended from the inner end of the extension section 61 toward the water outlet 51, and the end of the turning section 62 away from the extension section 61 is connected to the water outlet 51. Therefore, after the external water source enters the water inlet 41, it can pass through the extension section 61 and the turning section 62 in sequence, and then spray into the inside of the washing chamber 20 through the water outlet 51. The turning section 62 can make the water turn in the water flow channel 6 and be discharged smoothly from the water outlet 51.

[0079] In some embodiments, the width of the turning section 62 gradually widens in the direction toward the water outlet 51 , thereby facilitating an increase in the spray range at the water outlet 51 .
