Description

Technical Field

[0001] The present invention belongs to the technical field of washing machines, and more specifically, relates to a drum washing machine. Background Art

[0002] As a household appliance most widely used in people's daily life, the washing machine helps people get rid of the trouble of doing laundry and brings great convenience to people. Due to its advantages such as small washing wear, good washing effect, and water saving, the drum washing machine is generally favored by the majority of users.

[0003] Existing drum washing machines generally include a horizontally arranged outer tub and an inner tub. Since the outer tub is horizontally arranged, the mouth of the outer tub needs to be sealed during the laundry process of the drum washing machine. In addition, since the outer tub will vibrate during the laundry process, the installation of the outer tub needs to consider shock absorption and buffering. Therefore, the mouth of the outer tub of the existing drum washing machine is connected to the front panel through a window gasket. The window gasket can achieve a sealed connection between the outer tub mouth and the front panel, and at the same time, the window gasket has a corrugated structure to perform shock absorption and buffering.

[0004] However, during the laundry process of the drum washing machine, washing water will exist in the window gasket, and dirt in the washing water will also adhere to the window gasket. As the use time increases, more and more dirt adheres to the window gasket and becomes more firmly attached, which will cause secondary pollution of the clothes, seriously threatening the health of users, and this position can be directly seen by users, resulting in a poor user experience.

[0005] In view of this, the present invention is specifically proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a drum washing machine that cancels the method of sealing the mouth of the outer tub with the existing window gasket and eliminates the problem of dirt accumulation on the window gasket of the existing drum washing machine.

[0035] The present invention will be further described in detail below with reference to the embodiments.

[0036] As Figures 1 to 4 shown, the present invention provides a drum washing machine, including:

[0037] A cabinet 2, and a front panel 4 of the cabinet 2 is provided with a feeding port 3;

[0038] A door 6, which is installed on the feeding port 3 of the front panel 4 in an openable and closable manner;

[0039] An outer tub 15, which is arranged inside the cabinet 2, and the mouth of the outer tub 15 is opposite to the feeding port 3;

[0040] And a sealing decorative plate 21, which is fixedly installed on the mouth of the outer tub 15, and when the door 6 is closed, it maintains a sealed contact with the sealing decorative plate 21 through a sealing mechanism.

[0041] The drum washing machine of this embodiment cancels the existing method of sealing and connecting the window gasket to the mouth of the outer tub. By providing the sealing decorative plate 21, when the door 6 is closed, it maintains a sealed contact with the sealing decorative plate 21 through a sealing mechanism to achieve the sealing of the mouth of the outer tub, eliminating the problem of dirt accumulation on the window gasket of the existing drum washing machine. In addition, the sealing decorative plate of this embodiment can block the structure at the mouth of the outer tub, making the mouth of the outer tub cleaner and more beautiful, and improving the user experience.

[0042] As shown in Figure 2 and Figure 3 To achieve contact sealing between the machine door 6 and the mouth of the outer cylinder 15, as an implementation manner of this embodiment, the sealing mechanism described in this embodiment includes a first elastic sealing ring 23 provided on the mouth of the outer cylinder 15. When the machine door 6 is closed, the first elastic sealing ring 23 maintains a circular sealing contact with the inner wall surface of the machine door 6. In this embodiment, the first elastic sealing ring 23 directly maintains a circular sealing contact with the inner wall surface of the machine door 6 to achieve the sealing of the mouth of the outer cylinder by the machine door 6. The structure of the first elastic sealing ring 23 is simpler, it is not easy to accumulate dirt compared with the window gasket, and the sealing effect is increased by the extrusion at the mouth of the outer cylinder when the machine door 6 is closed.

[0043] Furthermore, the first elastic sealing ring 23 described in this embodiment includes a fitting portion 28 and a sealing portion 27. A circular sealing groove 29 is formed on the outer wall of the mouth of the outer cylinder 15. The sealing decorative plate 21 is fixedly installed on the outer wall of the mouth of the outer cylinder 15 through a connecting member 30, and at the same time, the fitting portion 28 is extruded into the sealing groove 29; when the machine door 6 is closed, the sealing portion 27 maintains a circular sealing contact with the inner wall surface of the machine door 6.

[0044] When installing the sealing decorative plate 21 in the drum washing machine of this embodiment, the fitting portion 28 of the first elastic sealing ring 23 is extruded into the sealing groove 29 to realize the installation of the first elastic sealing ring 23. The assembly method is simple and reliable. The sealing groove 29 of this embodiment is provided on the edge of the mouth of the outer cylinder 15 corresponding to the back of the sealing decorative plate 21. The fitting portion 28 is a circular elastic body, and the circular elastic body is extruded into the sealing groove 29 when the sealing decorative plate 21 is installed.

[0045] Furthermore, the sealing decorative plate 21 of this embodiment has a sunk groove 31, and an installation hole is formed in the sunk groove 31. The connecting member 30 passes through the installation hole and is fixed in the sunk groove 31; the first elastic sealing ring 23 includes a blocking portion 24 extending into the sunk groove 31 for blocking the connecting member 30. The blocking portion 24 of this embodiment restores elastic deformation after the installation of the connecting member 30, covers the connecting member 30 and the sunk groove 31, realizes the visual sense without connecting members, and increases its aesthetics.

[0046] Preferably, the connecting member 30 described in this embodiment can adopt a fastening screw.

[0047] Furthermore, the edge of the sealing trim panel 21 in this embodiment has a flanging 26. The sunken groove 31 is located inside the flanging 26. The first elastic sealing ring 23 includes a sleeving portion 25. The inside of the sleeving portion 25 has an open groove sleeved on the flanging 26. One side wall of the open groove extends horizontally to form a blocking portion 24. The other side walls of the open groove extend to form a mating portion 28 and a sealing portion 27 respectively. The edge of the trim panel 21 in this embodiment having the flanging 26 can increase the overall strength of the trim panel 21, avoid deformation when the outer cylinder 15 vibrates, and at the same time sleeve the first elastic sealing ring 23 on the flanging 26, preventing possible damage when users come into contact with the flanging 26, and at the same time increasing the overall aesthetics of the sealing trim panel 21.

[0048] Furthermore, the door 6 in this embodiment includes a door frame and a glass basin 7 installed on the door frame. When the door 6 is closed, an annular sealing contact is maintained between the sealing portion 27 and the glass basin 7.

[0049] As can be seen from the above, the window gasket is cancelled in the drum washing machine of this embodiment.
