Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and specifically relates to a dishwasher, in particular to a door opening rope structure of a front-opening dishwasher. Background Art

[0002] Dishwashers are devices that automatically wash tableware such as bowls, chopsticks, plates, dishes, knives, forks, etc. With the improvement of people's living standards, dishwashers have gradually become popular. In the prior art, with the continuous improvement of people's living standards, dishwashers have gradually entered the lives of families at home and abroad. Dishwashers have become normal household consumer goods, and the existing market demand for the selection of multiple appearance models of dishwashers is also increasing. In order to meet this demand, various dishwasher manufacturers have continuously launched a variety of new appearance models. When installing in the user's home and matching the appearance door panel, it is necessary to adjust the tension of the door body according to the weight of the appearance door panel so that the door body can be balanced and stable at all angles when opening and closing. Usually, some parts such as the outer shell need to be removed during installation to adjust the tension. The operation is relatively complicated, and ordinary consumers do not have the conditions and ability for disassembly and assembly. There are also some mechanisms on the market that can adjust the tension of the door body without disassembling the casing, but the structure is relatively complicated, there are many parts, and the disassembly and assembly process is also relatively troublesome. Therefore, it is necessary to further improve.

[0003] In particular, the door of the existing dishwasher is generally installed on the dishwasher body via a hinge structure, and then a hanging spring is installed on the body, and the hanging spring is connected to the dishwasher door via a pull rope, and the pull rope is used to apply the elastic force of the pull spring to the door body when it is opened and closed, so that the pull spring can be used for buffering during the opening and closing process of the dishwasher door. However, the connection between the existing pull rope and the door body is generally directly hung, and the ordinary hanging connection may cause the pull rope to become loose from tension due to the opening and closing action of the door body, resulting in the pull rope falling off.

[0004] Therefore, designing a structure that can ensure that the pull rope is simply and quickly hung and fixed to the door body, while avoiding the pull rope from falling off due to the tension and expansion of the pull rope, has become a technical problem that needs to be solved urgently by technical personnel in this field.

[0005] In view of this, the present utility model is proposed. Utility Model Content
