[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In an embodiment of the present invention, a motorhome waterway integrated system is disclosed, such as Figure 1 As shown, it includes a water station 1, a fresh water water circuit unit 2 and a water supply water circuit unit 3. The water station is provided with at least one water inlet and at least two water outlets. The first water outlet is connected to the fresh water water circuit unit 2, and the second water outlet is connected to the water supply water circuit unit 3. The water supply water circuit unit includes a cold water tank 33 provided with a refrigeration device 331, a hot water tank 31 provided with a heating device 311, and a hot water storage tank 32, wherein the hot water tank 31 and the cold water tank 33 are coupled to the second water outlet through a water pipe, the outside of the hot water storage tank 32 is connected to a heating mechanism through a water pipe, the heating mechanism is coupled to the second water outlet through a water pipe, and the hot water storage tank 32 and the hot water tank 31 are connected through a water pump connected to the water pipe.

[0027] When using, Figure 1As shown, the water channel integrated system mainly includes a water station 1, a fresh water channel unit 2 and a water supply channel unit 3, wherein the water station 1 is arranged above the fresh water channel unit 2 and the water supply channel unit 3, and the valve of the pipeline is opened, and the water in the water station 1 flows into the fresh water channel unit 2 and / or the water supply channel unit 3 due to gravity, and a water pump can also be arranged between the water station 1 and the fresh water channel 2 and the water supply channel unit 3 to prevent insufficient pressure, and the water inlet on the side wall of the water station 1 can be connected to the municipal natural water pipe to supply water to the water station 1, and the water station 10 can include two or more water outlets, so that water can be delivered to different water channel units, and for the fresh water channel unit 2, the water in the water station 1 is filtered and purified during the process of being transported to the fresh water channel unit 2 to prevent the water of the water channel integrated system from being unable to be used normally due to the pollution of the water source, and for the water supply channel unit 3, the water supply channel unit supplies water to the water-using equipment in the RV such as a bathtub, a faucet, etc., wherein the refrigeration equipment 331 includes a compressor, The condenser and the evaporator are connected, wherein the evaporator contacts the cold water tank, and the water in the cold tank 33 is directly cooled by the evaporator. The refrigeration device 331 can cool the water in the cold water tank 33, and the user can obtain low-temperature water by opening the valve of the cold water tank 33, and the heating device 311 can heat the hot water tank 33 to obtain water at room temperature or heated water. For the hot water storage tank 32, the water in the hot water storage tank 32 is first heated to a certain temperature by the heating mechanism, and the user can open the hot water storage tank 32 to obtain hot water at a constant temperature without waiting. The hot water storage tank 32 and the hot water tank 31 are connected by a water pump connected to a water pipe. When the hot water storage tank needs to be filled with water, the heating mechanism works, and the heating device 311 can also heat the water in the hot water tank 31 to the constant temperature calibrated by the hot water storage tank 32. Then the water pump transports the water in the hot water tank 31 to the hot water storage tank 32, thereby reducing the time used to fill the hot water storage tank 32 and improving the working efficiency of the water circuit integrated system.

[0028] The hot water storage tank 32 and the hot water tank 31 are both configured as a double-layer insulation structure. The heating device 311 includes a control device, a temperature sensing device connected to the control device, and a resistance heater. The output end of the control device is connected to the resistance heater. The insulation design of the hot water storage tank 32 and the hot water tank 31 can ensure that the heat loss of the water inside them is prevented, and frequent heating is not required. For the heating device 311, the user presets a temperature through the temperature adjustment key, and the signal is transmitted to the control device. The resistance heater starts to heat the water in the hot water tank 31, and the temperature sensing device detects the water in the hot water tank 31. When the water temperature in the hot water tank 31 is the same as the preset temperature, the heating device 311 stops working and the valve at the liquid outlet of the hot water tank 31 opens.
