Description

Technical Field

[0001] This utility model belongs to the field of drum washing machine technology, and specifically discloses a door glass structure for a drum washing machine. Background Technology

[0002] Currently, drum washing machines have a clearance surface at the top of the door glass to make way for components such as the clothes guard. In traditional drum washing machines, the clearance surface at the top of the door glass is flat, and the gap between the clearance surface and the top of the door seal (which is made of rubber) is set from small to large and then from large to small. This makes it easy for clothes to get stuck between the clearance surface and the top of the door seal, and clothes may enter the door seal interlayer, causing the door seal to rub against the seal. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a door glass structure for a drum washing machine that makes it difficult for clothes to enter the door seal interlayer and reduces the risk of rubbing against the door seal.

[0004] According to the technical solution provided by this utility model, the door glass structure of the drum washing machine includes a door glass mounting ring, a door glass water sealing cone ring and a door glass boss that are fixed in one piece. A clearance surface, a top transition surface and a side transition surface are provided at the upper end of the door glass boss. The clearance surface is smoothly connected to the top surface of the door glass boss through the top transition surface, and the clearance surface is smoothly connected to the side surface of the door glass boss through the side transition surface.

[0005] The clearance surface, top transition surface, and side transition surface are all convex arc surfaces; at the same height of the door glass boss, the clearance surface is lower than the side of the door glass boss.

[0006] Preferably, the yielding surface, the top transition surface, the side transition surface, and the side surface of the door glass boss are all arc surfaces. At the same height of the door glass boss, the arc radius of the yielding surface is greater than the arc radius of the side surface of the door glass boss, and the distance from any point on the arc of the yielding surface to the axis of the door glass boss is less than the arc radius of the side surface of the door glass boss.

[0007] Preferably, at the same height of the door glass boss, the arc of the yield surface is a minor arc, and the arc of the side of the door glass boss is a major arc.

[0008] This invention makes the gap between the relief surface on the door glass protrusion of the drum washing machine and the upper end of the door seal basically uniform, so that the clothes can move more smoothly in the gap between the relief surface and the upper end of the door seal, and the clothes are less likely to enter the door seal interlayer, reducing the risk of rubbing the door seal.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] A door glass structure for a drum washing machine, such as Figure 1-4 As shown, the device includes a fixed integrated door glass mounting ring 1, a door glass sealing cone ring 2, and a door glass boss 3. The upper end of the door glass boss 3 is provided with a clearance surface 3.1, a top transition surface 3.2, and a side transition surface 3.3. The clearance surface 3.1 is smoothly connected to the top surface 3.4 of the door glass boss through the top transition surface 3.2, and the clearance surface 3.1 is smoothly connected to the side surface 3.5 of the door glass boss through the side transition surface 3.3.

[0019] The clearance surface 3.1, the top transition surface 3.2, and the side transition surface 3.3 are all convex arc surfaces; at the same height of the door glass boss 3, the clearance surface 3.1 is lower than the side surface 3.5 of the door glass boss.

[0020] The yielding surface 3.1, the top transition surface 3.2, the side transition surface 3.3, and the side surface 3.5 of the door glass boss are all arc surfaces. At the same height of the door glass boss 3, the arc radius of the yielding surface 3.1 is greater than the arc radius of the side surface 3.5 of the door glass boss. The distance from any point on the arc of the yielding surface 3.1 to the axis of the door glass boss 3 is less than the arc radius of the side surface 3.5 of the door glass boss.

[0021] At the same height of the door glass boss 3, the arc of the yielding surface 3.1 is a minor arc, and the arc of the side surface 3.5 of the door glass boss is a major arc.

[0022] like Figure 5-8 As shown, in actual use, the door glass is fixed to the door assembly 4 of the drum washing machine through the door glass mounting ring 1. The door glass protrusion 3 extends into the door seal 5 (the door seal 5 is made of rubber). The door glass water-sealing cone ring 2 is interference-fitted with the door seal 5 to prevent washing water from flowing out. The clearance surface 3.1 is used to avoid components such as the clothes blocking block, preventing the clothes blocking block and other components from colliding with the door glass protrusion 3 when the drum washing machine is running.

[0023] Because the relief surface 3.1 is a raised arc surface, and at the same height as the door glass boss 3, the relief surface 3.1 is lower than the side surface 3.5 of the door glass boss, the gap between the relief surface 3.1 and the upper end of the door seal 5 is basically uniform. Clothes can move smoothly in the gap between the relief surface 3.1 and the upper end of the door seal 5, and clothes are less likely to enter the door seal interlayer, reducing the risk of rubbing against the door seal 5.

[0024] In this utility model, the top transition surface 3.2 can make the yielding surface 3.1 and the top surface 3.4 of the door glass boss smoothly transition, and the side transition surface 3.3 can make the yielding surface 3.1 and the side surface 3.5 of the door glass boss smoothly transition.

[0025] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
