Problems solved by technology

After tap water enters the barrel, it needs to be heated to 40-50°C by the PTC heating device. This heating process takes a certain amount of time. When the user requires the washing temperature to reach 60°C-80°C, or even 95°C in the drum self-cleaning mode , The heating process of tap water by PTC heating device will occupy most of the time of the whole washing process, which greatly reduces the efficiency of high-temperature washing of washing machine, and the PTC heating device is a large current passing through the metal heating wire, which makes the metal heat up and heats up the tap water, which cannot be realized. The separation of water and electricity is the most difficult safety issue in terms of the safety level requirements of washing machines today

Abstract

The invention belongs to the field of washing equipment, and in particular discloses a washing equipment and a control method. The washing equipment includes: a washing bucket for washing clothes; a circulating waterway including a circulating water outlet pipe and a circulating water return pipe. A heating device is arranged between the circulating water return pipes; the water in the washing bucket is discharged from the circulating water outlet pipe, heated by the heating device, and then returned to the washing bucket by the circulating water returning pipe; the water inlet pipeline is connected with the The heating device is connected, and the water in the water inlet pipeline is heated by the heating device and then flows into the washing tub through the circulating water return pipe. The washing equipment disclosed by the invention can effectively reduce the heating time of high-temperature washing, improve the heating efficiency and have higher safety performance.

Description

technical field [0001] The invention belongs to the field of washing equipment, in particular to a washing equipment and a control method. Background technique [0002] With the continuous improvement of living standards, washing machines have already entered thousands of households and become an important part of family daily life. Throughout the development of the washing machine, the washing temperature of the washing machine has changed from the normal tap water washing at the beginning to the common PTC heating tube to heat the tap water in the washing tub to achieve high-temperature washing, which improves the washing quality and makes the washing machine play the role of high-temperature sterilization. washing effect. [0003] Nowadays, the washing temperature of washing machines is generally maintained at 40-50°C. After tap water enters the barrel, it needs to be heated to 40-50°C by the PTC heating device. This heating process takes a certain amount of time. When ...
