System for mobile terminal to communicate with plurality of hot water supply devices

Abstract

A hot water supply system includes a plurality of hot water supply devices. The plurality of hot water supply devices include a first hot water supply device and a second hot water supply device. The first hot water supply device has a first hot water supply wireless communication module including a transceiver and a receiver adapted to wirelessly communicate with a mobile terminal. The plurality of hot water supply devices communicate with each other via a water-supply-to-water-supply-communication-path, wherein the first hot water supply device is configured to be paired with the mobile terminal to establish a first wireless communication path between the first hot water supply device and the mobile terminal for transmitting and receiving data, and hot water supply devices other than the first hot water supply device are configured to transmit and receive data to and from the mobile terminal via the first hot water supply device.

What is claimed is: 
     
         1 . A hot water supply system, comprising:
 a plurality of hot water supply devices, comprising:
 a first hot water supply device, comprising:
 a first hot water supply wireless communication module, comprising a transceiver and a receiver, adapted to wirelessly communicate with a mobile terminal; 
 
 a second hot water supply device; 
   wherein the plurality of hot water supply devices are configured to communicate with each other via a water-supply-to-water-supply-communication-path,   wherein the first hot water supply device is configured to be paired with the mobile terminal to establish a first wireless communication path between the first hot water supply device and the mobile terminal for transmitting and receiving data,   wherein hot water supply devices other than the first hot water supply device are configured to transmit and receive data to and from the mobile terminal via the first hot water supply device.   
     
     
         2 . The hot water supply system according to  claim 1 , further comprising:
 a communication relay apparatus, comprising a processor configured to communicate with each of the plurality of hot water supply devices,   wherein each of the plurality of hot water supply devices are directly wired to the communication relay apparatus,   wherein the communication relay apparatus is configured to receive a designation instruction from the mobile terminal via the first hot water supply device, the designation instruction specifying which one of the plurality of hot water supply devices the mobile terminal has designated to communicate with,   wherein the communication relay apparatus relays a communication between the mobile terminal and the one of the plurality of hot water supply devices that is designated in the designation instruction.   
     
     
         3 . The hot water supply system according to  claim 1 ,
 wherein the plurality of hot water supply devices are wired with each other in series,   wherein the first hot water supply device is configured to receive a designation instruction from the mobile terminal, the designation instruction specifying which one of the plurality of hot water supply devices the mobile terminal has designated to communicate with,   wherein when the one of the plurality of hot water supply devices that is designated in the designation instruction is connected downstream of the first hot water supply device, then the first hot water supply device only relays communication downstream of the first hot water supply device, such that the mobile terminal and the one of the plurality of hot water supply devices designated in the designation instruction may communicate,   wherein when the one of the plurality of hot water supply devices that is designated in the designation instruction is connected upstream of the first hot water supply device, then the first hot water supply device only relays communication upstream of the first hot water supply device, such that the mobile terminal and the one of the plurality of hot water supply devices designated in the designation instruction may communicate.   
     
     
         4 . The hot water supply system according to  claim 1 , further comprising:
 the mobile terminal;   wherein the mobile terminal includes a mobile terminal wireless communication module including a transceiver and a receiver,   wherein the mobile terminal is configured not to pair with any hot water supply device which has an RSSI value below or equal to a predetermined value.   
     
     
         5 . The hot water supply system according to  claim 1 , wherein the plurality of hot water supply devices, further comprises:
 a third hot water supply device.   
     
     
         6 . The hot water supply system according to  claim 1 , wherein each one of the plurality of hot water supply devices comprises:
 an inlet pipe;   an outlet pipe;   a heat exchanger, comprising a heat exchange tubing adapted to exchange heat; a processor.   
     
     
         7 . The hot water supply system according to  claim 1 , wherein the hot water supply devices other than the first hot water supply device do not include a wireless communication module.
