喷射式洗碗机专利技术分析

Patent Technology Analysis of the Jet Dishwashers

【目的】从专利文献的角度获得喷射式洗碗机的技术发展情况,以供科研人员作为研究参考。【方法】以专利IPC分类号A47L15/14(在清洗室中有固定陶器篮筐和喷射装置的洗碗机)及其下位点组作为检索基础,在INCOPAT专利检索平台获取截至2023年2月27日的专利申请作为分析对象,从申请量、申请人、地域分布等多个角度分析喷射式洗碗机专利技术情况,并选取几个重要创新主体的部分重点专利进行分析。【结果】经统计发现,喷射式洗碗机专利申请在2013年以后呈现较大幅度的增长,喷射式洗碗机专利的主要目的之一是扩大喷臂喷射清洗面积,使得洗碗机清洗覆盖范围更广;乐金、美的等企业在该领域的专利布局较为领先。【结论】喷射式洗碗机作为较为主流的洗碗机清洗结构,预计未来会朝着消除清洗死角及更加节能的方向发展。

[Purposes]This paper aims to obtain the technical development of jet dishwasher according to the patents,and to provide research reference for scientific researchers.[Methods]Based on the IPC number A47L15/14(dishwasher with fixed pottery basket and spray device in the cleaning room)and its sub-site group,the patent applications before February 27th,2023 were obtained on INCOPAT patent retrieval platform as the analysis object,and the patent technology of jet dishwasher was analyzed from the perspectives of application volume,applicants and geographical distribution,and some key patents of several important innovation subjects were selected for analysis.[Findings]According to the statistical results,the patent application of jet dishwasher has increased greatly after 2013.One of the main purposes of jet dishwasher patent is to expand the spray cleaning area of spray arm and make the cleaning coverage of dishwasher wider.LG,Midea and other companies are in the lead in patent layout in this field.[Conclusions]Jet dishwasher,as the main washing structure of dishwasher,is expected to develop in the direction of better cleaning effect,elimination of cleaning dead angle and more energy saving in the future.
