Description

Control method for water treatment device, and medium Technical Field The present invention relates to the field of water treatment apparatuses, and more particularly, to a control method for a water treatment apparatus, and a medium. Background Instant heating type drinking water equipment and hot water supply device are widely applied in daily life, and users expect to obtain hot water with proper temperature quickly when taking water, and long-time waiting is not needed. In the prior art, a common instant heating type water supply device adopts a structural design of a single circulating pump matched with a heat exchanger. In this design, the circulation pump is required to perform a dual task. On the one hand, in order to ensure that the user can realize instant heating when taking water, hot water needs to be driven to circulate in the system through the circulating pump in a non-water taking period, so that the heat exchanger is maintained in a certain temperature range, and the circulating pump is often required to continuously run for a long time or be frequently started and stopped. On the other hand, when a user takes water, the circulating pump is required to drive cold water to be preheated through the heat exchanger, and the preheated water is conveyed to the water outlet. This single pump design, which takes over multiple tasks, exposes significant drawbacks in practical use. Since the thermal cycle is a long-lasting condition, the circulation pump needs to be started frequently or operated for a long time during the standby period of the equipment, resulting in continuous wear of mechanical parts inside the pump body such as bearings, impellers, seals, etc. The long-time operation can also cause the temperature of the motor winding to rise, and the aging of the insulating material is accelerated. With the accumulation of the service time, the failure rate of the circulating pump is obviously increased, the service life is far lower than that of other parts in the equipment, and the circulating pump becomes a short plate for limiting the reliability of the whole equipment.
