A control system for a whirlpool bath installation, including a single input source wiring for connecting to an input source of high voltage AC electrical power having a nominal current rating. A plurality of high voltage output connections are connected to the input source through a corresponding plurality of switches, for power connections to a respective high voltage load devices, whose cumulative nominal current draw ratings exceeds the current rating of the input source. An electronic controller controls states of the switches in response to user input commands. The electronic controller implements an algorithm or a set of rules preventing a system utilization of the high voltage loads from exceeding a total current draw exceeding said nominal maximum current rating.

Disclosed is a control box. The control box is internally provided with a first chamber, and the first chamber is used for accommodating a control component. The control box is also internally provided with an air supply system for supplying air to a water pool body. The air supply system comprises an air suction part having a housing, the housing is provided with an air inlet and an air outlet, and the air inlet is communicated with the first chamber; the air suction part further comprises an air pump provided in the housing, and when the air pump is started, air in the first chamber can be suctioned into the housing by means of the air inlet. The air supply system further comprises a valve part provided with a pipeline, the pipeline is provided with an air intake port and an air supply port, the air intake port is communicated with the air outlet of the housing, and the air supply port is used for being communicated with the water pool body; when the valve part is opened, the air suctioned into the housing can flow into the water pool body along the pipeline. According to the present invention, the working environment in the first chamber can be kept dry, so that the service life of the control component is prolonged. The present invention further provides a massage water pool.

An inflation system, a massage pool air supply system, and an inflation method. The inflation system includes: a first gas channel (20) and a second gas channel (30); the first gas channel (20) has a gas inlet port and a gas outlet port; the gas inlet port is used for being connected to a gas supply apparatus (10), and the gas outlet port is used for communicating with a gas chamber (51) of the inflated object (50); the first gas channel (20) can be switched between a first state and a second state; the second gas channel (30) is arranged in parallel to the first gas channel (20); the second gas channel (30) is used for communicating with the gas chamber (51); a gas pressure sensor (40) is provided on the second gas channel (30); in the first state, a gas pressure in the gas chamber (51) measured by the gas pressure sensor (40) does not reach a set value, and the first gas channel (20) can inflate the gas chamber (51); in the second state, the gas pressure in the gas chamber (51) measured by the gas pressure sensor (40) reaches the set value, and the first gas channel (20) can stop inflating the gas chamber (51). The inflation system can prevent over inflation and can effectively protect the inflated object.
