[0001] The invention relates to the technical field of RV antifreeze, in particular to an RV antifreeze control system and an RV antifreeze water storage tank. Background Art

[0002] RVs are a means of transportation that combines travel and living. Users often drive RVs to travel in the wild. The temperature changes greatly in the wild environment, so it is particularly important to prevent the water source inside the RV from freezing.

[0003] The existing antifreeze waterway described in the open document CN219790012U can effectively solve the problem of pipeline antifreeze, and the open document CN215244554U can solve the problem of heating the water tank for antifreeze based on the energy source; The energy reserves of the RV itself are limited. It is necessary to ensure the warmth of the residents in the car first, and then solve the problem of water antifreeze. Therefore, the water tank cannot be heated and antifreeze indefinitely. When the RV energy warning is issued, only the warmth needs of the residents in the RV can be prioritized. At this time, the heating source of the water in the water tank disappears, so the water tank will be frozen. After the water tank is frozen, the basic living water in the RV cannot be guaranteed. Summary of the invention

[0004] When the RV is short of energy, it cannot provide excess energy to keep the water tank antifreeze, causing the water tank to freeze and making water unavailable in the RV.

[0005] The present invention aims at the deficiencies in the prior art and provides an antifreeze control system for a recreational vehicle and an antifreeze water storage tank for the recreational vehicle.

[0007] The beneficial effect is that when the RV is short of energy, the water tank body can activate physical isolation for insulation to ensure that there is basic drinking water in the RV. At the same time, salt is added to the outer water source to reduce the freezing point so that it can be used for flushing operations.

[0008] In the above scheme, preferably, an adding device is further provided in the water tank body, and the adding device adds additives to the outer water source after the dividing device divides the water tank body, so as to reduce the freezing temperature of the water source.

[0010] In the above scheme, preferably, the additive is salt.

[0011] Its beneficial effect is that after being dissolved in water, the water becomes non-toxic and the freezing temperature is reduced.

[0012] An antifreeze water storage tank for a motorhome is applied with an antifreeze control system for the motorhome. An annular ring for a partition is arranged in the water tank body. A channel opening for the circulation of internal water source is opened on the annular ring. A sealing block is also elastically slidably arranged in the annular ring.

[0016] In the above scheme, preferably, the annular ring is provided with three layers, and three water pipes for flushing, three stop devices and three adding devices are also provided.

[0017] The beneficial effect is that the multiple layers of insulation make the innermost water source less affected by the external temperature. At the same time, the layered protection means that after all are started, even if the outermost layer of water source freezes, there are still two layers of flushing water inside to ensure the flushing water.

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Example

[0028] See also Figure 1-Figure 7 A motorhome antifreeze control system includes a water tank body 1, a control system and an adding device 2. The control system includes a central control unit, a communication device and a detection device. The communication device is connected to an external network, and obtains the future temperature forecast of the location in the network. The central control unit calculates the energy surplus according to the future temperature forecast. When it is concluded that the energy surplus is insufficient, the water tank body 1 is controlled to perform self-insulation treatment.

[0029] The water tank body 1 is provided with three ring-type annular rings 11, so that the water tank body 1 is divided into four layers of water storage cavities from the inside to the outside, and the annular rings 11 and the water tank body 1 are both made of hollow thermal insulation materials, so that each layer has a thermal insulation effect, and each annular ring 11 is provided with a channel opening 12 from top to bottom, so that the cavity in the water tank body 1 is connected when the channel opening 12 is opened, and a blocking block 111 is provided on the annular ring 11 for guiding sliding. The blocking block 111 can block the channel opening 12 when extended, so that the cavity in the water tank body 1 is separated inside and outside.

[0030] The rear end of the blocking block 111 is connected to one end of a pull rope, and the other end is connected to the winch. The rear end of the blocking block 111 touches one end of an elastic member, and the other end of the elastic member touches the sliding cavity. In the initial state, that is, when the channel opening 12 is open, the winch is locked, and the elastic member is in a compressed state. When it is necessary to close it, the winch is unlocked, and under the action of the elastic member, the blocking block 111 slides out, thereby blocking the channel opening 12 to separate the inside and the outside.

[0031] The detection device includes a temperature sensor, which is arranged outside the vehicle and in each partition cavity, and can detect the temperature conditions at each position in real time. The central control unit controls the opening of the blocking block 111 according to the real-time changes of the temperature sensor, and then controls the water tank body 1 to keep itself warm.

[0032] The adding device 2 includes a storage box 21, and a plurality of cavities are arranged in the storage box 21, each cavity extends to an opening at the bottom of the storage box 21, and each cavity extends to a channel opening at the bottom, and a switch plate 22 is arranged on the opening at the bottom of the storage box 21 for horizontal sliding, and the switch plate 22 can open different numbers of channel openings by horizontal sliding, and powdered salt is stored in each cavity in the storage box 21, and a pulling device is connected to the rear end of the switch plate 22, and the pulling device can be an electric push rod, and the central control unit controls the pulling stroke of the electric push rod according to the temperature recognized by the temperature sensor.

[0033] A drinking water outlet pipe 13 is connected to the bottom of the center position of the water tank body 1, which is connected to the drinking water faucet on the RV to provide drinking water for the RV. A flushing water pipe 14 is connected to the bottom surface of the water tank body 1 outside each annular ring 11, and the flushing water pipe 14 is connected to the drinking water outlet pipe 13 through a pipe. A stop device 15 is arranged on the rear pipe connected to each corresponding flushing water pipe 14. The stop device 15 includes a stop plate 151 which is elastically guided and slidably arranged. One end of a second pull rope is connected to the upper end of the stop plate 151, and the other end is connected to a winch connected to the corresponding blocking block 111. The winch is connected to a motor, and the motor is controlled by the central control unit.

[0034] When the channel opening 12 is opened, the blocking plate 111 is in a tightened state, and the anti-passage plate 151 is also pulled upward, the elastic member above is in a compressed state, and the anti-passage device 15 is in a smooth state. When the capstan is unlocked, the blocking plate 111 blocks the channel opening 12, and the straight plate 151 also disconnects the flushing water pipe 14 from the drinking water outlet pipe 13. The water outside the annular ring 11 can only be used for flushing. Since the additive is salt, the flushing water can be used to flush items including food. At the same time, when changing the water source in the water tank, only a simple flushing is required for normal use.

[0035] When the central control unit calculates that the energy is sufficient according to the future temperature trend, it controls the heating unit arranged in the middle position of the water tank body 1 to heat the water in the water tank when the temperature drops, thereby heating the water in the water tank to prevent freezing.

[0036] When the central control unit calculates that the energy is insufficient based on the future temperature trend, and according to the predicted temperature trend, the temperature outside the vehicle will drop below 0 degrees, the water tank's self-insulation measures are activated. When the temperature outside the vehicle drops to greater than or equal to 5 degrees and less than 10 degrees, the sealing block 111 on the first annular ring 11 is controlled to slide out, thereby forming a first separation layer to separate the inner and outer water sources. The annular ring 11 and the sealing block 111 are both made of insulation material. Therefore, when the outer water temperature continues to drop, the inner water source can be kept warm for a certain period of time.

[0037] When the detection device detects that the temperature of the outer water source drops to 0-1 degrees, the central control unit controls the switch plate 22 at the bottom of the adding device 2 to open, and the salt in the multiple cavities in the storage box 21 slides down into the first outer cavity. The cavity between the first annular ring 11 and the outer wall of the water tank body 1 is the first outer cavity, the cavity between the first annular ring 11 and the second annular ring 11 is the second outer cavity, and the cavity between the second annular ring 11 and the third annular ring 11 is the third outer cavity.

[0038] When salt dissolves in water, the freezing point of water drops, and the temperature continues to drop. The switch plate 22 is opened at a larger distance, so that more salt dissolves in the water, causing the freezing point of water to continue to drop, thereby preventing the water in the first outer cavity from freezing. When the blocking block 111 blocks the channel opening 12, the outermost stop plate 151 blocks the channel between the flushing water pipe 14 and the drinking water outlet pipe 13, so that the water in the first outer cavity can only be used for flushing and cannot enter the drinking water faucet in the RV.

[0039] Under the heat preservation effect of the first-layer annular ring 11 and the sealing block 111, when the water temperature of the inner circle drops to greater than or equal to 2 degrees and less than 5 degrees, the central control unit controls the sealing block 111 in the second-layer annular ring 11 to slide out, thereby forming a second heat-insulating separation layer. Similarly, the channel between the flushing water pipe 14 and the drinking water outlet pipe 13 in the second layer is blocked, and the water in the second layer can only flow out from the flushing water pipe for flushing operations. When the water source temperature in the second outer cavity drops to 0-1 degrees, the central control unit controls the switch plate 22 at the bottom of the adding device 2 to open, and the salt dissolves in the water to lower the freezing point of the water, thereby preventing the internal water source from freezing.

[0040] After being insulated by the first and second insulation separation layers, when the water temperature in the second annular ring 11 drops to a temperature greater than or equal to 0 degrees and less than 2 degrees, the blocking block 111 in the third annular ring 11 is controlled to slide out to form the third insulation separation layer. At this time, the heating unit in the center of the water tank body 1 is started and operates at low power to ensure that the water source temperature in the third annular ring 11 is above 0 degrees, ensuring a certain amount of drinking water.

[0041] Similarly, the channel between the flushing water pipe 14 and the drinking water outlet pipe 13 in the third layer is blocked, and the water in the third layer can only flow out from the flushing water pipe for flushing operations. When the water source temperature in the third outer cavity drops to 0-1 degrees, the central control unit controls the switch plate 22 at the bottom of the adding device 2 to open, and the salt dissolves in the water to lower the freezing point of the water, thereby preventing the internal water source from freezing.

[0042] The specific temperature values ​​within the temperature range described above can be set by the user in the central control unit as required.

[0043] Use minimal energy to retain a certain amount of drinking water, while lowering the freezing point of the water source in the outer separation layer to prevent freezing. Even if the outermost layer of water freezes, there are still two layers of water inside that can be used for flushing, which ensures the water for flushing to a certain extent, thereby guaranteeing the basic water use in the RV.

[0044] Its working principle or usage is as follows: When the central control unit calculates that the energy is sufficient according to the future temperature trend, it controls the heating unit arranged in the middle position of the water tank body 1 to heat the water in the water tank when the temperature drops, thereby heating the water in the water tank to prevent freezing.

[0045] When the central control unit calculates that there is insufficient energy based on future temperature trends, and the temperature outside the vehicle will drop below 0 degrees according to the predicted temperature trend, the water tank's self-insulation measures are activated. According to the difference in temperature drop, the partition layers at different positions are opened to insulate the innermost layer of drinking water. At the same time, salt is dissolved in the outer layer of water to lower its freezing temperature to prevent freezing. At the same time, the outer layer of water is used for flushing, and through different levels of insulation, it is ensured that there is water for flushing.

[0046] After the temperature rises, the central control unit reminds the user to change the water source. The central control unit controls all the capstans to rotate, and re-inserts the blocking block 111 into the annular ring 11. All cavities in the water tank body 1 are connected. At this time, drainage is carried out and then water is filled to complete the replacement of the water source in the water tank. The water discharged from the water tank can be used for flushing operations.

[0047] At the same time, the user adds a sufficient amount of salt into each storage box 21 for use in the next emergency water tank insulation. Example

[0048] See also Figure 1-7 , compared with the first embodiment, the difference is that the central control unit has a different control method for blocking the three-layer annular ring 11, which is the same as both.

[0049] When the central control unit calculates that the energy is insufficient based on the future temperature trend, and according to the predicted temperature trend, the temperature outside the vehicle will drop below 0 degrees, the water tank self-insulation measures are activated. When the temperature outside the vehicle drops to greater than or equal to 5 degrees and less than 10 degrees, the three winch motors are controlled to release the pull ropes at the same time, so that the blocking blocks 111 in the three annular rings 11 block the channel opening 12 to form three insulation separation layers.

[0050] As the water temperature in the outer cavity drops by 0-1 degree, the adding device in each layer is started in turn to add salt to the water to reduce the freezing temperature of the water in the added layer.

[0051] The three-layer separation is initially performed to reduce the influence of the outside temperature on the temperature of the innermost layer of drinking water. This control method can only guarantee the most basic amount of drinking water, while the first embodiment can guarantee the most basic drinking water as much as possible according to the actual temperature.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
