Water quality monitoring method for water supply system, water supply system, and refrigeration apparatus

A water supply system, comprising:

• a water container, a water inlet pipe connected to the water container and a water outlet pipe connected to the water container, wherein a water inlet valve is disposed on the water inlet pipe, a drain valve and a water quality detection device are disposed on the water outlet pipe, the water quality detection device is connected to a controller, and the controller is configured to control the water inlet valve and the drain valve according to a water quality parameter detected by the water quality detection device through actions including:
• controlling the drain valve to convey water from the water container to the water outlet pipe of the water container;
• detecting that a water level of the water container is maintained at a preset water level;
• obtaining, through the water quality detection device, a water quality parameter in the water outlet pipe in response to the detecting that the water level of the water container is maintained at the preset water level;
• determining whether the water quality parameter meets a standard;
• and
• controlling the drain valve to drain the water in the water container in response to the water quality parameter does not meet the standard.

A refrigeration apparatus, comprising a water supply system, the water supply system including a water container, a water inlet pipe connected to the water container and a water outlet pipe connected to the water container, wherein a water inlet valve is disposed on the water inlet pipe, a drain valve and a water quality detection device are disposed on the water outlet pipe, the water quality detection device is connected to a controller, and the controller is configured to control the water inlet valve and the drain valve according to a water quality parameter detected by the water quality detection device through actions including:
