The technical solution of the utility model can improve the shape structure and material characteristics of the door seal of the drum washing machine, increase the shock absorption and buffer area, and minimize the force of the outer tub pulling the door panel when the washing machine is dehydrated at high speed, thereby improving the vibration amplitude of the whole machine , greatly improving the quality of the product.

Description

Shock-absorbing door seal for drum washing machine

technical field

The utility model relates to parts of a drum washing machine, in particular to a door seal of a drum washing machine with high-efficiency buffering vibration.

Background technique

The door seal is a product that effectively maintains the airtightness of the container, and the door seal used to assemble and connect the outer tub of the drum washing machine and the door panel plays a vital role in the sealing performance of the drum washing machine: on the one hand, it buffers the drum washing machine The violent vibration during high-speed dehydration, on the other hand, seals the glass of the washing chamber door to avoid water leakage. However, the existing drum washing machine door seal structure lacks rationality. When the washing machine is dehydrating at a high speed, the shock-absorbing buffer zone extends from the rear fixing groove to the front fixing groove, and even the vibration reaches the front fixing groove. It is still not reduced to zero. As a result, the door panel may be pulled, so that the dehydration vibration of the washing machine is transmitted from the inside to the outside, increasing the vibration amplitude of the whole machine and affecting the quality of the drum washing machine.

Contents of the invention

The purpose of this utility model is to design a shock-absorbing door seal of a drum washing machine, which is used to improve the vibration of the washing machine during high-speed dehydration.

The shock-absorbing door seal of the utility model drum washing machine, its technical solution is: the ring-shaped door seal includes an integrally formed front fixing groove, rear fixing groove and hoop face, which are respectively nested on the washing machine door panel and the outer tub , characterized in that: a shock-absorbing buffer zone composed of at least one "S"-shaped shock-absorbing belt is provided between the rear fixing groove of the door seal and the hoop surface. Moreover, the elastic shock-absorbing strength of the shock-absorbing belt is stronger than the elastic shock-absorbing strength of the front fixing groove and the rear fixing groove, while the elastic shock-absorbing strength of the hoop surface between the front fixing groove and the shock-absorbing buffer zone is between in between.

Further, the side of the rear fixing groove is also provided with a stop protrusion.

By adopting the technical solution of the utility model, by improving the shape structure and material characteristics of the door seal, the shock absorbing and buffering area is increased, and the force of the outer tub pulling the door panel is minimized when the washing machine is dehydrated at high speed, thereby improving the overall machine. At the same time, the added stop convex part also has the beneficial feature of preventing the laundry roll from being stuck in the gap and hindering the rotation of the inner tub, which greatly improves the quality of the product.

Detailed ways

The purpose, features and advantages of the shock-absorbing door seal of the drum washing machine of the present invention will be further described in detail in conjunction with the embodiments and corresponding drawings, so as to deepen the understanding of the essence of the present invention.

As shown in Fig. 1 and Fig. 2, the inside front view and the side view axis sectional view of the door seal of the present invention can be seen that the door seal 1 is in the shape of a closed ring and is made of soft elastic material. In conjunction with the structural schematic diagram of the door seal of the present invention shown in Figure 3, that is, the enlarged schematic diagram of part A in Figure 2, it can be clearly seen that the circular door seal 1 includes an integrally formed front fixing groove 12, a rear fixing groove The groove 13 and the hoop surface 14 are respectively used for nesting and assembling the door panel and the outer tub of the washing machine. In particular, the door seal 1 is also designed with a shock-absorbing buffer zone composed of an "S"-shaped shock-absorbing belt 11 between the rear fixing groove 13 and the hoop surface 14 . Wherein, the elastic damping strength of the shock-absorbing belt 11 is stronger than the elastic damping strength of the front fixing groove 12 and the rear fixing groove 13, and the elastic damping strength of the hoop surface 14 between the front fixing groove 12 and the shock-absorbing buffer zone is in between. In this way, the shock-absorbing and buffering radiation area is increased, and the force of the outer tub pulling the door panel is minimized when the washing machine is dehydrated at high speed, thereby improving the vibration amplitude of the whole machine.

In addition, it can be found from Fig. 3 that there is also a stop protrusion 15 on the side close to the rear fixing groove 13, and the stop protrusion 15 can completely seal the bottom of the outer barrel after the entire door seal and the outer barrel are assembled. interface, so that the door seal has the beneficial performance of preventing the laundry roll from being stuck in the gap and hindering the rotation of the inner tub, further reducing the possibility of violent vibration of the front-loading washing machine.

In summary, it is only an application example of the technical solution of the present utility model, and the number and combination of the shock absorbing belts 11 will not be limited. All technical solutions formed by equivalent transformation or equivalent replacement fall within the scope of the utility model. within the scope of the claimed rights.
