Washing and drying all-in-one machine and dry judging method thereof

Abstract

The invention discloses a washing and drying all-in-one machine and a dry judging method thereof. The washing and drying all-in-one machine and the dry judging method thereof are characterized in that the load capacity in a drying barrel is detected in advance to calculate the operation estimated time T0 of a drying process under the corresponding load capacity. Heat drying is conducted on loads in the drying barrel, the drying time is shortened, and drying energy consumption is lowered. Heating wires stop working after meeting any following conditions that the temperature value in the drying barrel is obviously changed; the temperature value in the drying barrel exceeds an upper limit; the time T of the entire drying process reaches the operation estimated time T0 of the drying process. Moreover, when the three conditions all lose efficacy, the heating wires are controlled to stop working through the following condition that the entire drying time T is larger than the maximum operation time Tmax of the drying process. Through the washing and drying all-in-one machine and the dry judging method thereof, the purpose of accurately judging the work time of a drying machine is achieved, and the effect of lowering the power consumption of the washing and drying all-in-one machine is achieved.

Description

technical field [0001] The invention relates to an integrated washing and drying machine in the field of washing machines and a drying judging method thereof. Background technique [0002] Along with the continuous upgrading and optimization of the integrated washing and drying machines in the industry, the integrated washing and drying machines with larger capacity have become the development direction of the industry, and can also meet the requirements of users for washing large clothes. Therefore, the laundry washing and drying all-in-one machine with the three-in-one function of washing, washing and drying is also upgraded along with the upgrading of the industry. The following points have become the current research direction and trend of products in the industry for the drum-type laundry washing-drying machine: whether the clothes are dried during the drying process; The dryness of the clothes can be stopped in time to save energy. [0003] However, in the current pr...
