Dish washer, and method and apparatus for detecting weight of tableware in dish washer

Abstract

The invention discloses a dish washer, and a method and apparatus for detecting the weight of tableware in the dish washer. The dish washer comprises a dish washer body, an accommodation chamber disposed inside the dish washer body and a heating device disposed inside the dish washer. The method comprises following steps: enabling the dish washer to enter a water feeding stage so as to add washing water with a preset volume into the dish washer body; detecting the temperature in the dish washer so as to obtain the initial temperature; controlling the heating device to heat the washing water according to the preset power until the temperature in the dish washer reaches the target temperature; acquiring the heating time that the temperature in the dish washer is heated to the target temperature from the initial temperature; and calculating the weight of the tableware in the accommodation chamber according to the heating time. According to the invention, the weight of the tableware actually placed by a user can be calculated just through an original temperature sensor and without additional sensing devices and detection devices, so that the dish washer can be intelligently controlled according to the weight of the tableware, washing effects can be guaranteed, and the waste of resources can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of washing appliances, in particular to a dishware weight detection method for a dishwasher, a dishware weight detection device for a dishwasher, and a dishwasher. Background technique [0002] When the user uses the dishwasher, the number of tableware placed each time will vary. However, in the design of related dishwashers, due to the complexity of its structure, it is difficult to detect the weight of tableware by adding sensing devices and other methods. [0003] Based on this, in order to ensure the washing effect of the dishwasher, related technologies often design parameters such as the water intake, washing time, and heating temperature of the dishwasher according to the maximum tableware loading capacity or the nominal loading capacity of the dishwasher. However, Its disadvantage is that water and electricity will be wasted when there are fewer tableware placed in the dishwasher. Contents of the ...
