Description

Technical Field

[0001] The utility model relates to an intelligent antifreeze device, in particular to an intelligent antifreeze device for a waterway of a recreational vehicle. Background Art

[0002] One of the main problems facing RV water systems during cold winters is freezing. Since water expands when it freezes, this can cause damage to pipes, water tanks, or other water system components. Traditional methods of preventing freezing include wrapping insulation around water pipes or keeping faucets running slightly during cold weather, but these methods are neither ideal nor water-saving.

[0003] In order to solve this problem, in recent years, it is urgent to start developing intelligent antifreeze devices, using modern technology and automatic control to prevent the water system from freezing and cracking, solving the inconvenience and inefficiency of traditional antifreeze methods, and providing a more intelligent and automated antifreeze solution to protect the RV water system from the cold winter climate.

DETAILED DESCRIPTION

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1 and Figure 2 The intelligent antifreeze device for the water line of the RV shown includes:

[0021] A water tank 1 is provided with a temperature sensor 2, and the water tank outputs a first pipeline 4 and a second pipeline 5 through a water pump 3; in this example, there are two water tanks 1, and each water tank 1 is connected to a corresponding water pump 3, and the first pipelines 4 on the two water tanks 1 merge into a third pipeline 9 for output, and a first electric valve 12 is installed on the third pipeline 9, and the first electric valve 12 is electrically connected to the controller 6, and the controller automatically controls the shutoff of the first electric valve 12 to determine whether the third pipeline 9 is conductive.

[0022] A controller 6 is electrically connected to and receives a signal from the temperature sensor 2;

[0023] The thermal protection component includes a relay 7 and a heating wire 14. The control end of the relay 7 is connected to the controller 6, the input end of the relay 7 is connected to the power supply end of the RV, and the heating wire 14 is wound on the side wall of the pipeline connected to the third pipeline 9; the heating wire 14 is spirally wound on the side wall of the third pipeline 9.

[0024] When the controller receives a low temperature signal from the temperature sensor, the controller adjusts the heating time and power by receiving the signal from the temperature sensor, and activates the heating wire through the relay to increase the temperature of the water in the third pipeline to prevent the water from freezing; wherein, the output end of the controller is connected to the control end of the relay, and the controller activates the relay by sending a low-level signal (for a DC system) or a cold contact (for an AC system), and the output end of the temperature sensor is connected to the input end of the controller. The temperature sensor can be a thermistor (such as an NTC thermistor) or a thermocouple, which is used to detect the temperature of the water in the water tank. When the controller receives the signal from the temperature sensor and determines that the temperature is lower than the set threshold, the controller sends a signal to the relay to close it, thereby allowing current to pass through the heating wire to start heating.

[0025] The heat exchanger 8 has a water pipe input interface 8a connected to the pipeline connected to the second pipeline 5, and the water is output from the water pipe output interface 8b after passing through the heat exchanger 8; the heat exchanger 8 has an antifreeze input interface 8c and an antifreeze output interface 8d connected to the antifreeze circulation system of the RV. The second pipelines 5 on the two water tanks 1 merge into a fourth pipeline 10 for output, and the fourth pipeline 10 is connected to the water pipe input interface 8a. The fourth pipeline 10 is installed with a second electric valve 13, which is electrically connected to the controller. The controller automatically controls the second electric valve 13 to be turned on and off, and determines whether the fourth pipeline 10 is conductive. The antifreeze input interface 8c is connected to the engine antifreeze circulation system of the RV, and the antifreeze output interface 8d is connected to the engine antifreeze circulation system of the RV to realize heat exchange of water with antifreeze when the engine is started. When the engine is started, the antifreeze will circulate in the engine antifreeze circulation system of the RV, and the antifreeze enters the heat exchanger 8 from the antifreeze input interface 8c. The controller opens the second electric valve 13 and starts the water pump 3. The water in the water tank 1 is collected to the fourth pipeline 10 through the second pipeline 5 in turn and then connected to the water pipe input interface 8a. After entering the heat exchanger 8 through the water pipe input interface 8a to exchange heat with the antifreeze, the heated water is output through the water pipe output interface 8b. When the engine is turned off, the controller closes the second electric valve 13, and no water is input into the fourth pipeline 10 for heat exchange, and the antifreeze will not flow into the heat exchanger 8.

[0026] It should be understood that the third pipeline 9 and the water pipe output interface 8b of the utility model are both connected to the water system of the RV to supply water for it, forming a double water tank and double water supply. During this period, the temperature of the water in the water tank is automatically monitored by the controller, and the water supply path is switched according to the vehicle usage status. When the temperature is lower than the set threshold, the electric heating wire is automatically started for heating, and no manual intervention is required, which improves the efficiency and safety of antifreeze. Alternatively, the original antifreeze circulation system of the RV is used to exchange heat with the water system through a heat exchanger to improve thermal efficiency. At the same time, the heat generated by the antifreeze when the engine is running is also used. The heat exchange using the original antifreeze circulation system of the RV can effectively utilize the heat generated when the engine is running, improve thermal efficiency, and reduce energy consumption. The former is suitable for use when the RV is parked, and the latter is suitable for use when the RV is driving, which is suitable for different usage scenarios.

[0027] Among them, the application of the dual-tank dual-circuit water supply system in RVs has the following benefits: through two independent water tanks and water supply channels, even if one water tank or channel fails, the other can still work normally to ensure that the water demand inside the RV is met. The dual-tank design can increase the water capacity of the RV to meet the needs of long-term or multi-person use, and improve the applicability and convenience of the RV. The controller automatically monitors the temperature of the water in the water tank and automatically switches the water supply channel according to the temperature, or starts the heating wire heating to ensure that the water will not freeze due to low temperature, which improves the applicability of the RV in cold environments.

[0028] In summary, the dual-tank dual-circuit water supply system provides an efficient, safe and reliable water system solution for RVs by improving water supply stability, capacity, temperature control and thermal efficiency, as well as providing flexibility and easy-to-maintain operation.

[0029] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
