Description

Technical Field

[0001] The utility model relates to the technical field of sensor application, in particular to a dishwasher with a TOF object detection and distance measurement sensor. Background Art

[0002] The dishwasher is a highly efficient appliance in the modern kitchen, designed specifically to handle the tedious task of post-meal washing. Using high-pressure water and specialized detergents, it automatically cleans, sterilizes, and dries dishes, significantly saving both manpower and time. Dishwashers are equipped with multiple spray arms that spray water in all directions, ensuring every dishware, even hard-to-reach corners, is thoroughly cleaned. Furthermore, the intelligent control system allows users to select the appropriate wash mode based on the degree of soiling and type of dishes, saving both energy and the environment. Some high-end models also feature features such as fast wash speed, silent operation, and smart connectivity, further enhancing ease and comfort of use. Dishwashers not only reduce the burden of household chores but also, with their efficient sterilization capabilities, provide a healthier and safer dining environment for families, making them an indispensable kitchen assistant for modern families.

[0003] After searching, a Chinese patent with publication number CN210888522U discloses a dishwasher with an automatic door opening device, including a casing and a door. An inner tank is provided in the casing, and an accommodating space is formed between the casing and the inner tank. A driving mechanism and a push rod are provided in the accommodating space. An accommodating cavity is provided in the door, and an insertion opening is provided in the door. A lock hook structure is provided in the accommodating cavity. The lock hook structure includes a locking block and a positioning spring, and the push rod is provided with a positioning hole; the locking block is provided with a guide surface, which guides the locking block to insert into or disengage from the positioning hole, and the push rod is controlled by gear rack drive, motor screw drive, motor chain drive and hydraulic cylinder drive to realize automatic opening or closing of the door.

[0004] At present, although the existing dishwasher technology can greatly facilitate our lives, it still has certain limitations with the development of society. For example, although the door of a traditional dishwasher can be electrically controlled to open and close, when we hold the dishes in both hands and put them into the dishwasher, we still need to place the dishes on top of the dishwasher or on the kitchen countertop, and then free our hands to click or touch the control screen on the dishwasher to open the door, and then put the dishes in for cleaning, resulting in inconvenience in operation.
