[0002] With the improvement of people's living standards and the enhancement of health awareness, the cleanliness and hygiene of underwear has received more and more attention. As underwear is a close-fitting garment, its cleanliness is directly related to our health. The traditional hand-washing method is not only time-consuming and laborious, but also difficult to guarantee the cleaning effect. Therefore, underwear washing machines came into being and became one of the indispensable household appliances in modern families.

[0003] In the comparative document of a washing machine door panel assembly proposed by announcement number CN219731399U, it is specifically proposed that "it includes a washing machine body, a cleaning chamber is provided inside the washing machine body, a drum is rotatably arranged in the inclined chamber, a receiving chamber connected to the cleaning chamber is provided on the outer side of the washing machine body, a cover plate is hingedly installed at the receiving chamber, positioning holes are symmetrically provided at the outer edge of the receiving chamber, a positioning chamber is provided inside the cover plate, and a positioning assembly that cooperates with the positioning hole for positioning is provided in the positioning chamber; the positioning assembly includes a swivel and a latch, a bevel gear ring is provided on one side of the swivel close to the cover plate, and a bevel gear is fixed on one side of the screw rod close to the bevel gear ring."

[0004] The inventors found that the comparative documents use a positioning assembly and a sealing ring to perform secondary sealing on the cover plate, but the device requires manual work to push the rotating ring for positioning and sealing after the cover plate is closed. There are many steps, which does not conform to people's concept of using simple furniture products. For this reason, we propose a locking structure for the door panel of a small washing machine.

DETAILED DESCRIPTION

[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Embodiment 1

[0025] Reference Figure 1-5 , a locking structure for a door panel of a small washing machine comprises a washing machine housing 1 and a door panel 2 hinged on the upper end surface of the washing machine housing 1, a receiving surface 3 is provided at the junction of the upper end surface of the washing machine housing 1 and the door panel 2, a locking assembly 4 is provided at the hinged portion of the receiving surface 3 facing away from the door panel 2, a sealing assembly 5 is provided on the inner side of the locking assembly 4, a latch assembly 6 is provided at the position corresponding to the door panel 2 and the locking assembly 4, a conical block 7 is provided on the inner side of the latch assembly 6, and the conical block 7 is used to drive the sealing assembly 5 to seal the junction between the door panel 2 and the receiving surface 3.

[0026] Reference Figure 5 The locking assembly 4 includes a cavity 41 arranged on the upper end surface of the receiving surface 3, a fixing block 42 slidably arranged at both ends of the cavity 41, a triangular protrusion 43 respectively arranged on the fixing block 42, and a return spring a44 arranged at the rear end of the fixing block 42.

[0027] It is worth noting that the fixing block 42 is driven to slide left and right in the cavity 41 by a return spring a44 at the rear end of the fixing block 42, so that the latch assembly 6 can be locked and released.

[0028] Reference Figure 4The latch assembly 6 includes a rectangular latch 61 fixedly arranged on the lower end surface of the door panel 2, protrusions 62 arranged on both sides of the rectangular latch 61, U-shaped blocks 63 slidably arranged on both sides of the rectangular latch 61, and a return spring b64 arranged between the door panel 2 and the U-shaped block 63.

[0029] In this embodiment, the protrusion 62 is limited by the triangular protrusion 43, and the fixing block 42 is squeezed toward the middle by the return springs a44 on both sides, so that the triangular protrusion 43 can clamp the protrusion 62 to achieve locking between the door panel 2 and the washing machine housing 1.

[0030] Reference Figure 4-5 The height of the protrusion 62 is lower than the height of the triangular protrusion 43. The width of the rectangular latch 61 is consistent with the width of the protrusion 62.

[0031] It is worth noting that, by manually squeezing the U-shaped block 63, the fixed block 42 is squeezed by the U-shaped block 63, so that the triangular protrusion 43 releases the restriction on the protrusion 62, and the door panel 2 can be opened smoothly.

[0032] Reference Figure 3 The sealing assembly 5 includes a groove 51 arranged on the receiving surface 3, a rubber ring 52 arranged in the groove 51, and pistons 53 slidably arranged at both ends of the rubber ring 52.

[0033] In this embodiment, the pistons 53 at both ends are moved into the rubber ring 52 by pressing down the conical block 7, increasing the air pressure inside the rubber ring 52 and causing the rubber ring to expand, thereby achieving sealing between the door panel 2 and the receiving surface 3.

[0034] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art under the technical guidance of the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
