Detailed Description

Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.

The flexible gasket 107, the door assembly 10, and the laundry treating apparatus 1 of the laundry treating apparatus 1 according to the embodiment of the present invention are described below with reference to the accompanying drawings. The laundry treating apparatus 1 may be a dryer, a washing machine, or a washing and drying integrated machine.

For the sake of clarity in describing the specific working principle of the flexible sealing ring 107, the laundry treating apparatus 1 and the door assembly 10 according to the embodiment of the present invention will be described first.

As shown in fig. 1 to 3, the laundry treating apparatus 1 according to an embodiment of the present invention may include an outer tub 20, an inner tub (not shown), a coupling ring 70, a door lock 40, and a door assembly 10.

Specifically, as shown in fig. 5, the outer tube 20 has a front nozzle 201, the inner tube is provided in the outer tube cavity of the outer tube 20, the coupling ring 70 is provided on the outer tube 20 and around the front nozzle 201, and the door assembly 10 is movably provided on the outer tube 20 or the coupling ring 70 to open or close the front nozzle 201, that is, the door assembly 10 may be provided on the outer tube 20 or on the coupling ring 70. Specifically, the outer tube 20 defines an outer tube cavity, a front tube opening 201 communicating with the outer tube cavity is provided on a front side wall of the outer tube 20, the inner tube is provided in the outer tube cavity, and an outer peripheral wall of the inner tube and an inner peripheral wall of the outer tube 20 are provided at an interval. Thus, when the laundry treating apparatus 1 is needed to be utilized, the door assembly 10 can be opened first, so that laundry is conveniently placed into the inner drum through the front drum opening 201, and then the front drum opening 201 is closed by utilizing the door assembly 10, so that the laundry treating apparatus 1 can work normally; after the laundry treatment is completed, the door assembly 10 can be opened to facilitate the removal of the laundry from the drum through the front drum opening 201. When the laundry treating apparatus 1 is not required to be used, the opened state of the door assembly 10 may be maintained or the front nozzle 201 may be closed with the door assembly 10 according to the use habit of the user.

Specifically, as shown in fig. 12 and 13, the door assembly 10 according to the embodiment of the present application includes a door glass 104, a door inner ring 105, a door outer ring 106, and a flexible seal ring 107, the door inner ring 105 being located at the rear side of the door outer ring 106, i.e., the side close to the outer cylinder 20.

The flexible gasket 107 is disposed around the door glass 104, and in a state where the door assembly 10 is closed, the connection ring 70 abuts against the flexible gasket 107 to close the front nozzle 201. In the closed state of the front nozzle 201 before the door assembly 10 is closed, the purpose of closing the front nozzle 201 can be achieved by the sealing and abutting of the flexible sealing ring 107 and the connecting ring 70, and on the other hand, a good sealing effect can be achieved.

Generally, the laundry treating apparatuses 1 in the market, such as drum washing machines, are provided with a door gasket on a machine body, and the door gasket cooperates with the door assembly 10 to achieve sealing purpose. The door sealing ring is mostly made of rubber. The laundry treating apparatus 1, such as a drum washing machine, is liable to have defects such as blackening, fouling, mold, etc. of the door seal on the door seal after long-term use. These drawbacks can lead to a very poor user experience for the user. Although the connecting ring 70 of the present application may be used instead of the door gasket to seal against the door assembly 10, there is a problem of poor sealing. In view of this, according to the laundry treating apparatus 1 of the embodiment of the present application, by providing the connection ring 70 on the outer tub 20 and having the connection ring 70 disposed around the front tub opening 201, and simultaneously providing the flexible sealing ring 107 in the door assembly 10, the sealing abutment with the connection ring 70 in the closed state of the door assembly 10, it is possible to effectively solve the problem of poor sealing, and to avoid the problem of water leakage or air leakage of the laundry treating apparatus 1.

Referring to fig. 14 to 16, the door glass 104 includes a door body 1041 and an annular flange 1042, the annular flange 1042 being provided at a front end edge of the door body 1041 and surrounding the door body 1041, the annular flange 1042 being sandwiched between the door inner ring 105 and the door outer ring 106. Specifically, for example, as shown in fig. 11 to 13, the door body 1041 is formed in a bowl shape protruding rearward, the annular flange 1042 is provided at an outer peripheral edge of the front side opening of the door body 1041, the door inner ring 105 is located at a rear side of the annular flange 1042, the door outer ring 106 is located at a front side of the annular flange 1042, and the annular flange 1042 is sandwiched between the door inner ring 105 and the door outer ring 106.

The flexible sealing ring 107 of the laundry treatment apparatus 1 according to the embodiment of the present invention includes an annular body 1071, wherein a rear portion of the body 1071 is adapted to be in abutting engagement with an abutting member such as the connecting ring 70 described above, and the body 1071 is deformed under the abutting action of the abutting member, an inwardly protruding abutting bead 10711 is provided on an inner peripheral wall of a front portion of the body 1071, and the abutting bead 10711 extends in a circumferential direction of the body 1071. Here, "inner" means a direction toward the central axis of the body 1071.

Specifically, the body 1071 may be disposed around the outer peripheral wall of the door glass 104, the abutment bead 10711 may be disposed around the outer peripheral wall of the door glass 104, for example, the body 1071 may be disposed around the outer peripheral wall of the door body 1041, the abutment bead 10711 is disposed on a portion of the inner peripheral wall of the body 1071 away from the outer cylinder 20, and the abutment bead 10711 abuts against the outer peripheral wall of the door body 1041, whereby, by disposing the abutment bead 10711 on the inner peripheral wall of the front portion of the body 1071, that is, on the side away from the outer cylinder 20, on the one hand, the abutment bead 10711 can be utilized to achieve a sealing effect by the abutment between the abutment bead 10711 and the door glass 104, and on the other hand, since the abutment bead 10711 is further away from the connecting ring 70, when the abutment engagement of the abutment bead 10711 with the door glass 104 does not affect the abutment of the flexible seal ring 107 with the connecting ring 70, the flexible seal ring 107 is deformed due to the force applied to the flexible seal ring 107, and the flexible seal ring 107 has a larger deformation margin, thereby being more forcefully applied to the opening and closing of the door assembly 10; for example, when the door assembly 10 is closed, the connection ring 70 is in abutting sealing with the flexible seal ring 107, the force between the connection ring 70 and the flexible seal ring 107 may deform the flexible seal ring 107 in the vertical direction (deformation mainly occurs near one end of the connection ring 70, the rear end shown in fig. 13-16, and a specific deformation process will be described later), so if the abutting bead 10711 is provided near the rear end of the flexible seal ring 107, the deformation space of the flexible seal ring 107 is greatly occupied, such as the deformation space in the vertical direction is occupied, so that the door assembly 10 is tightly matched between the inner side of the connection ring 70 and the outer side of the flexible seal ring 107 after the door assembly is closed, thereby making the door assembly 10 difficult to open and close; in this embodiment, the abutment bead 10711 is provided at the end far from the connecting ring 107 (far from the outer cylinder 20), so as to reduce the intrusion of the deformation space of the end of the flexible seal ring 107 near the connecting ring 107, and avoid the problem that the door assembly 10 is difficult to open and close.

The rear end of the body 1071 has a radial dimension larger than that of the rear end of the door glass 104, and a gap is provided between the inner peripheral wall of the body 1071 and the outer peripheral wall of the door glass 104 in a state in which the abutment is separated from the body 1071, that is, when the flexible seal ring 107 is not acted upon by an external force, that is, when the door assembly 10 is in an open state. Thereby, the deformation of the flexible seal 107 is facilitated, and the opening and closing of the door assembly 10 is further facilitated. It will be appreciated that when the flexible seal 107 is compressed, there may be no longer any gap between the inner peripheral wall of the body 1071 and the outer peripheral wall of the door glass 104 due to compression deformation, but there may also be a gap.

According to the flexible seal ring 107 of the laundry treatment apparatus 1 of the embodiment of the present invention, by providing the abutment bead 10711 at the front portion of the inner peripheral wall of the body 1071, i.e., at the side far from the outer tube 20, on one hand, the sealing effect can be ensured by the abutment between the abutment bead 10711 and the door glass 104, and on the other hand, since the abutment bead 10711 is far from the connection ring 70, the abutment fit of the abutment bead 10711 and the door glass 104 does not affect the deformation of the flexible seal ring 107 due to the force applied to the flexible seal ring 107 by the connection ring 70 when the flexible seal ring 107 abuts against the connection ring 70, the flexible seal ring 107 has a larger deformation margin, thereby being more forceful to the opening and closing of the door assembly 10.

The door assembly 10 of the laundry treating apparatus 1 according to the embodiment of the present invention has the above-described flexible sealing ring 107, and thus has all the above-described advantageous effects.

According to the laundry treating apparatus 1 of the embodiment of the present invention, by providing the above-described door assembly 10, it has all the advantageous effects of the above-described door assembly 10.

In some embodiments of the invention, the abutment bead 10711 is one. Therefore, the sealing effect can be ensured, the structure is simple, and the manufacturing cost can be reduced; more importantly, the abutting ribs 10711 are arranged singly, so that the invasion of deformation space of the flexible sealing ring 107 is further reduced, and the opening and closing resistance of the door assembly 10 is further reduced.

Optionally, the abutment bead 10711 is integrally formed with the body 1071. Therefore, the structure of the integrated part not only can ensure the structure and performance stability of the abutting convex rib 10711 and the body 1071, but also is convenient to form and simple to manufacture, redundant assembly parts and connection procedures are omitted, the assembly efficiency of the abutting convex rib 10711 and the body 1071 is greatly improved, the connection reliability of the abutting convex rib 10711 and the body 1071 is ensured, moreover, the integral strength and stability of the integrated structure are higher, the assembly is more convenient, and the service life is longer.

According to some alternative embodiments of the present invention, as shown with reference to fig. 14-16, the flexible seal 107 includes a first flexible segment 1072 and a second flexible segment 1073.

That is, the first flexible section 1072 and the second flexible section 1073 are respectively disposed at two axial ends of the body 1071, wherein the first flexible section 1072 is disposed at one end, i.e. the rear end, of the body 1071 close to the outer cylinder 20, the second flexible section 1073 is disposed at one end, i.e. the front end, of the body 1071 far away from the outer cylinder 20, and in the closed state of the door assembly 10, the first flexible section 1072 is in sealing contact with the connecting ring 70, and the second flexible section 1073 is sealed between the annular flange 1042 and the door inner ring 1074. Thereby, the structure of the flexible seal ring 107 is simple.

According to some alternative embodiments of the invention, the flexible sealing ring 107 is an integral piece. Therefore, the structure of the integrated part not only can keep the structure and performance stability, but also is convenient to form and simple to manufacture, redundant assembly parts and connecting procedures are omitted, the assembly efficiency is greatly improved, and moreover, the integral strength and stability of the integrated structure are higher, the assembly is more convenient, and the service life is longer.

Optionally, the flexible sealing ring 107 is a rubber or silicone piece. Therefore, the sealing effect is good and the cost is low.

According to some further embodiments of the present invention, there is a multi-stage sealing engagement between the first flexible segment 1072 and the connecting ring 70. Thereby, the reliability of sealing fit between the flexible sealing ring 107 and the connecting ring 70 is improved, the problem of poor sealing is further effectively solved, the problem of water leakage or air leakage of the clothes treatment device 1 is avoided, and the use experience of a user is further improved.

As some alternative embodiments of the present invention, the first flexible segment 1072 includes an annular first leg 10721 and an annular second leg 10722, one end of the first leg 10721 and one end of the second leg 10722 are each connected to the body 1071, the other end of the first leg 10721 and the other end of the second leg 10722 extend in directions away from each other, respectively, and in the closed state of the door assembly 10, the first leg 10721 and the second leg 10722 are each in sealing abutment with the connecting ring 70. Therefore, the two-stage sealing matching relation between the connecting ring 70 and the flexible sealing ring 107 can be realized, the reliability of sealing matching between the flexible sealing ring 107 and the connecting ring 70 is improved, the problem of poor sealing is further effectively solved, the problem of water leakage or air leakage of the clothes treatment equipment 1 is avoided, and the use experience of a user is further improved.

In some alternative embodiments of the present invention, referring to fig. 11, the coupling ring 70 includes a first plate 701, a second plate 702, and a beading plate 703, the first plate 701 extends in a ring shape in a circumferential direction of the front nozzle 201 and is coupled to the outer cylinder 20, one end of the second plate 702 is coupled to an inner circumferential wall of the first plate 701 and the second plate 702 extends forward, the beading plate 703 is coupled to a front end of the second plate 702 and surrounds the second plate 702, and in a closed state of the door assembly 10, referring to fig. 16, the first leg 10721 abuts the second plate 702 and the second leg 10722 abuts the beading plate 703.

Specifically, referring to fig. 15, in the opened state of the door assembly 10, the first leg 10721 and the second leg 10722 are in the freely telescopic state, at this time, the other end of the first leg 10721 extends backward in a direction approaching the outer tube 20, the second leg 10722 extends in a direction away from the center axis of the body 1071, during the gradual movement of the door assembly 10 from the opened state to the closed state, the hemming plate 703 first contacts the second leg 10722, the force of the hemming plate 703 and the second leg 10722 causes the second leg 10722 to deform and gradually deform obliquely forward in a direction away from the outer tube 20, and the deformation of the second leg 10722 drives the first leg 10721 to gradually deform and abut against the second plate 702, so that in the closed state of the door assembly 10, as shown in fig. 16, sealing abutment of the second leg 10722 with the hemming plate 703 and sealing abutment of the second plate 702 with the first leg 10721 can be achieved. Therefore, the two-stage sealing matching relation between the connecting ring 70 and the flexible sealing ring 107 can be realized, the reliability of sealing matching between the flexible sealing ring 107 and the connecting ring 70 is improved, the problem of poor sealing is further effectively solved, the problem of water leakage or air leakage of the clothes treatment equipment 1 is avoided, and the use experience of a user is further improved.

In some alternative embodiments of the present invention, the top blocks 10712 are provided on the outer peripheral wall of the body 1071, for example, the top blocks 10712 are plural, the top blocks 10712 are arranged along the circumferential direction of the body 1071, the top blocks 10712 are located on the front side of the first flexible section 1072, specifically, the top blocks 10712 are located between the first flexible section 1072 and the second flexible section 1073, and in the state where the door assembly 10 is closed, i.e., in the state where the first flexible section 1072 is abutted by the abutment member, the side surface of the second leg 10722 facing away from the outer cylinder 20 abuts against the top blocks 10712. Therefore, by arranging the top block 10712, not only can the sealing effect be improved, but also the second leg 10722 and the first leg 10721 are prevented from moving during the working process of the clothes treating apparatus 1, the reliability of the sealing fit between the flexible sealing ring 107 and the connecting ring 70 is ensured, in addition, when the door assembly 10 is in the opening state from the closing state, the top block 10712 has a certain driving effect on the second leg 10722, and the shape recovery of the second leg 10722 and the first leg 10721 is promoted, so that the reliability of the working of the flexible sealing ring 107 is ensured.

In the process of matching the connecting ring 70 with the flexible sealing ring 107, a possible deformation process of the flexible sealing ring 107 is as follows:
