Technical Field

[0001] The utility model relates to the technical field of recreational vehicles and waterway systems, in particular to an anti-icing system for waterways of recreational vehicles. Background Art

[0002] RVs have the functions of both a "house" and a "car", but their attributes are still cars. They are mobile and have the basic facilities necessary for home use, and are very popular among users. With the rise of RV tourism, the use environment of RVs is becoming increasingly diverse. Especially in low temperature environments, how to ensure the normal operation of the RV water system and prevent the water from freezing has become an urgent problem to be solved.

[0003] In cold areas, when the temperature is below 0℃, the water in the water system of a traditional RV will begin to freeze, causing the water pipes to be frozen, making it impossible for RV users to use water normally. Utility Model Content

The utility model adopts a method of circulating the water channels to prevent the water channel system of the motorhome from freezing.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A motorhome waterway anti-icing system comprises a first water tank and a second water tank, wherein the first water tank is connected to a domestic water pipeline through a first pipe, and a main water pump and a first check valve are arranged on the first pipe.

[0007] The second water tank is connected to the domestic water pipeline through a second pipe, and a backup water pump and a second check valve are provided on the second pipe. A return pipe connected to the second water tank is provided on the second pipe, and one end of the return pipe connected to the second pipe is located on the side of the backup water pump and the second check valve close to the domestic water pipeline, and a valve is provided on the return pipe.

[0008] Furthermore, the valve is a manual valve.

[0021] like Figure 1 As shown, a motorhome waterway anti-icing system includes a first water tank 1 and a second water tank 2. The first water tank 1 is connected to a domestic water pipeline 3 through a first pipe 11. A main water pump 12 and a first check valve 13 are provided on the first pipe 11.

[0022] The second water tank 2 is connected to the domestic water pipeline 3 through the second pipe 21, and a backup water pump 22 and a second check valve 23 are provided on the second pipe 21. A return pipe 24 connected to the second water tank 2 is provided on the second pipe 21, and one end of the return pipe 24 connected to the second pipe 21 is located on the side of the backup water pump 22 and the second check valve 23 close to the domestic water pipeline 3, and a valve 25 is provided on the return pipe 24.

[0023] Embodiment 1:

[0024] like Figure 1 As shown, in this embodiment, a first water tank 1 and a second water tank 2 are included, wherein the first water tank 1 is a main water tank, which is arranged outside the RV, and the second water tank 2 is an auxiliary water tank, which is arranged inside the RV;

[0025] The first water tank 1 is connected to the domestic water pipeline 3 through the first pipe 11. A main water pump 12 and a first check valve 13 are sequentially arranged on the first pipe 11 along the waterway direction. The main water pump 12 is used to pump the water in the first water tank 1 into the domestic water pipeline 3. The first check valve 13 is used to prevent the water in the domestic water pipeline 3 from flowing back into the first water tank 1.

[0026] The second water tank 2 is connected to the domestic water pipeline 3 through the second pipe 21. A backup water pump 22, a second check valve 23 and a return pipe 24 are sequentially arranged on the second pipe 21 along the waterway direction. One end of the return pipe 24 is connected to the second pipe 21, and the other end is connected to the second water tank 2, forming a circulating waterway of the second water tank 2 → the second pipe 21 → the return pipe 24 → the second water tank 2, and a valve 25 is arranged on the return pipe 24.

[0027] The standby water pump 22 is used to pump the water in the second water tank 2 to the domestic water pipeline 3 or the return pipe 24 , and the second check valve 23 is used to prevent the water in the domestic water pipeline 3 or the return pipe 24 from flowing back.

[0028] like Figure 2 As shown, a battery 63 and a first switch 61 and a second switch 62 connected in parallel to the positive and negative poles of the battery 63 can be arranged in the RV, wherein the first switch 61 is connected to the main water pump 12, and the first switch 61 is used to control the opening and closing of the main water pump 12, and the second switch 62 is connected to the backup water pump 22, and the second switch 62 is used to control the opening and closing of the backup water pump 22.

[0029] Preferably, the first water tank 1 and the second water tank 2 are both provided with an overflow port 5 and a water inlet 4 .

[0030] When in use, a temperature sensor can be used to detect the ambient temperature (including inside / outside the vehicle) or the temperature of the water in the water system. When the temperature is lower than a preset value, the second switch 62 and the valve 25 are turned on to start the standby water pump 22 so that the water in the second water tank 2 starts to circulate and form living water, thereby preventing the pipes of the second water tank 2 from freezing. When the temperature is lower than a preset value, the second water tank 2 can be used normally.

[0031] During specific implementation, the flow rate of the standby water pump 22 can be adjusted according to the temperature to achieve a better anti-icing effect; if the temperature is too low, a heating device can be added to heat the water in the circulating water circuit.

[0032] The above is an example of the best implementation of the utility model, and the parts not described in detail are common knowledge of ordinary technicians in this field. The protection scope of the utility model is based on the content of the claims, and any equivalent transformation based on the technical inspiration of the utility model is also within the protection scope of the utility model.
