But car as a house water supply system of high capacity self-control and aseptic storage pure water

Technical Field

The utility model relates to a car as a house water supply system field specifically is a but car as a house water supply system of pure water is stored to large capacity self-control and aseptic.

Background

With the rise of self-driving tour, the motor home as an important component of the self-driving tour is also developed at a high speed. At present, more than two hundred families exist in domestic car manufacturing or refitting factories, and manufacturers providing accessories for car as a house are rather numerous. In view of the fact that the market of the motor homes in China starts late for nearly a hundred years abroad, the technical scheme of the similar products in the foreign country is basically carried out in the aspect of the motor home production and modification technology in China.

As the touring car is basically in a field, the supply, storage and application of water as a living necessity are very important. The development of touring car camps for providing maintenance, supply and service for touring car travel has been popularized in recent hundred years abroad, and the touring car camps are started in China. Therefore, the system related to the water consumption of the motor home needs to be reasonably improved according to the actual conditions of China.

Due to the loss of the recreational vehicle camps, water is supplemented to places such as high-speed service areas, gas stations, roadside restaurants, roadside public toilets, lawn irrigation water in scenic spots, residents and the like during the travel of the recreational vehicle, the quality of the supplemented water is uneven, water which can be added to many places does not necessarily meet the national quality standards and requirements of drinking water for residents, and the sanitary condition of the water adding environment is difficult to meet the requirements, so that the quality of a water source for supplying water to the recreational vehicle is not guaranteed. The most basic water supply system on existing motor homes is shown in fig. 1. The quality of water obtained by a water source without quality assurance through the water supply system can not be guaranteed, so that most car owners can only wash the water in the water storage tank of the motor home without drinking and eating the water. The car-fellow can generally purchase bottled water or bottled water in addition and be used for drinking and eating, and is very inconvenient, also uneconomical, simultaneously because car as a house storing space is limited, the bottled water quantity of buying just also is limited, purchases to lack and is difficult to ensure the continuation of the journey backup of car as a house in the travel, purchases to have more and will make originally little car as a house inner space seem to promote narrow and crowded more.

To improve this situation, many car owners and some car manufacturers have modified the water system of the car houses to improve the water quality, as shown in fig. 2, 3 and 4. However, these solutions have a common problem: clear water after the processing all stores in the stereoplasm box, need set up the air vent on box or the water feeding pipeline to guarantee that the car as a house is adding water or the atmospheric pressure balance in the water tank of water in-process. This results in convection and exchange of air between the interior of the storage tank and the exterior of the motor home. The parking environment of the motor home is constantly changed along with the traveling process, no matter whether the changed environment has air pollution, the large probability of the motor home traveling and parking destinations is that plants and trees are flourishing and flowers and plants are flourishing, pollen spores and the like rich in air can enter the water storage tank, and the organic substances can be propagated in the environment that the water and the air exist in the water storage tank and are attached to the inner wall of the water tank, so that algae can be generated for a long time to form so-called green water pollution. Therefore, even if the filtered water quality reaches the drinking standard, no safe and clean storage environment exists, and the eating requirement is still difficult to meet.

Detailed Description

Referring to fig. 5, the utility model discloses a but car as a house water supply system of large capacity self-control and aseptic storage pure water, including filler 1, filter equipment and the water storage container that communicates in proper order, the water storage container is the water storage bag, the water storage bag includes the bag body, the top of bag body is equipped with one-way discharge valve 11, 11 control gas of one-way discharge valve can only be followed the bag and arrange outside the bag, the bottom of bag body is equipped with output pipeline 9. The "capsule" is a structure made of soft organic polymer materials such as rubber, which are common in the art. The filtering device can be PP cotton or active carbon or ceramic filter element or their combination. When water enters or exits, the water storage bag can correspondingly expand or contract, and the pressure in the bag body is always balanced with the external atmospheric pressure by matching with the one-way exhaust valve. The one-way exhaust valve 11 is a structure commonly used in the field, when water enters the capsule body, the one-way exhaust valve 11 can gradually exhaust the gas in the water storage capsule until the capsule body is completely filled with water. When the water storage bag is used, in order to avoid the water storage bag from being damaged and provide a support for the water storage bag, a shell is generally arranged outside the water storage bag, and is fixedly connected with one part of the water storage bag, so that the situation that the bag body falls down and the like when being contracted is prevented, the one-way exhaust valve 11 is led to move to the bottom of the bag body and the like, and the exhaust is influenced, for example, the structure in fig. 5 is that the one-way exhaust valve 11 is fixed on the top of the water storage bag and the top of the shell at the same time, and the air exhaust can also be realized by adopting other structures, for example, the part of the side wall of the water storage bag.

As an improvement of the above technical solution, a main water supply valve 10 is further provided between the filler 1 and the filtering device. After water is added, the water supply main valve 10 is closed, so that other water supply systems behind the water supply main valve 10 can be a closed environment isolated from the outside, external air is prevented from entering, and the safety of water quality is further ensured.

In order to improve the quality of the self-produced water of the water supply system of the motor home, a part of the water supply systems of the motor home adopt household reverse osmosis filtration equipment. The water supply system of the prior motor home with the household reverse osmosis filtering device is generally shown in figure 4, and the purified water prepared by the scheme has very high quality and is the safest and best quality drinking water. The scheme is the scheme which can guarantee the quality of drinking edible water in a water supply system of a motor home at home and abroad at present. However, the solution still has great disadvantages, which severely limits the application and development of the solution. First, need self priming pump suction intake when intaking, also need the booster pump pressure boost during the reverse osmosis in order to satisfy the required pressure of pump income reverse osmosis membrane, need two pumps from the water source to making the pure water like this and just can accomplish whole water treatment, occupation space is big, and the cost is higher. Secondly, the reverse osmosis water making machine has difficult waste water discharge. If the water is directly discharged to the outside of the automobile, the water stain on the outside of the automobile when the automobile stays in a parking place is uncomfortable, and also obstructs other people, so that the water stain is not preferable; if the sewage is discharged to the ash water tank for collecting the sewage of the caravan, the volume of the ash water tank is limited, the sewage for collecting the kitchen bath is tense, and the sewage is discharged more frequently by adding the wastewater of the water generator, so that the caravan can be discharged only by driving the caravan to a specific position suitable for discharging the ash water, and the drainage frequency is increased, which is inconvenient and burdensome in practice; if with waste water backward flow to clear water tank back circulation filtration once more, this method both can not influence parking ground environmental sanitation like directly discharging the car outward, also can not influence the rate of utilization of grey water tank like discharging to grey water tank, but the water in the clear water tank is through continuous waste water backward flow circulation filtration back, and its quality conductivity can produce and pile up, not only influences the quality of preparing the pure water after the conductivity risees to certain numerical value, also can seriously influence reverse osmosis membrane's life for car as a house reverse osmosis system water machine application cost risees by a wide margin. At present, all motor home manufacturers do not have a recognition and solution for solving the problem of conductivity accumulation of the clean water tank, and how to solve the problem is the premise for improving the application of the motor home reverse osmosis purified water technology. Thirdly, the storage of purified water is difficult. The purified water produced by the existing household purified water making machine is generally stored in a 3.2 gallon pressure water storage tank, the size of the purified water is similar to that of a 5 kilogram gas tank, the actual effective water storage capacity is about 10L, and one device can be installed in the limited inner space of a motor home, and can occupy other storage spaces in a more way. The pressure water storage tank has small water storage capacity and slow water outlet flow, so that the drinking is not problematic, and the pressure water storage tank is obviously insufficient for cooking. The household reverse osmosis water generator is not used for cooking in household application, and is more inconvenient on a motor home. If the purified water produced by the water making machine is stored in a special purified water tank, the problems of small water storage capacity and slow water outlet flow can be solved, but the pollution problem caused by air inlet and exhaust of air holes can be caused.

The utility model discloses a water storage bag scheme has effectively solved the problem that the difficulty was deposited to the pure water. The problems with the first and second points described above are still not solved. The following describes a water supply system equipped with reverse osmosis, improved on the basis of the above-described solution:

the first improvement scheme comprises a water supply pipeline and a purified water preparation loop, wherein the purified water preparation loop is connected to the output end of the water supply pipeline, the water supply pipeline comprises a water filling port 1, a water supply main valve 10, a self-priming pump and a primary filter 2, the two water storage bags are arranged to form a clean water bag 7 and a purified water bag 8 respectively, the purified water preparation loop consists of a booster pump, a reverse osmosis membrane component 6 and the clean water bag 7, the wastewater output end of the reverse osmosis membrane component 6 is communicated with the clean water bag 7, the clean water bag 7 is communicated with the input end of the reverse osmosis membrane component 6 through the booster pump, and the filtered water output end of the reverse osmosis membrane component 6 is communicated with the purified water bag; all be equipped with the TDS probe in pure water bag 8 and the clear water bag 7, the TDS probe all disposes the TDS display. This kind of scheme can carry out real-time supervision to the TDS value of the water in clear water bag 7 and the pure water bag 8, can force to close the work of inhaling the booster pump 4 certainly when the TDS value of water is too high in clear water bag 7, changes the clear water in the clear water bag 7. When the TDS value of the water in the purified water bag 8 is too high, the reverse osmosis membrane can be replaced. Therefore, the problem of difficult wastewater discharge of the reverse osmosis water generator in the existing water supply system of the motor home is solved. However, the first improvement still has the technical problems of high cost and two pumps when the normal pressure water in the basin or the barrel needs to be sucked.

Therefore, on the basis of the scheme, the method is further improved:

will the self priming pump is omitted to the water supply line, and the output inserts between clear water bag 7 and the booster pump, the booster pump adopts from inhaling booster pump 4. Therefore, the self-priming water supply or purified water pressurization preparation can adopt the self-priming booster pump 4 with two purposes, and the first technical problem is solved. However, this structure also has the disadvantages that when water is supplied, all water needs to be treated by reverse osmosis before entering the clean water bag 7, the water supply efficiency is slow, and the feasibility is poor.

Therefore, on the basis of the scheme, the following improvement is carried out:

a first valve 3 is arranged between the clean water bag 7 and the self-priming booster pump 4, and the output end of the water supply pipeline is connected between the first valve 3 and the self-priming booster pump 4; still include the water supply branch road, the front end of water supply branch road is even between from inhaling booster pump 4 and reverse osmosis membrane subassembly 6, rear end intercommunication clear water bag 7, water supply branch road middle part is equipped with second valve 5. When water is supplied, two situations are distinguished: the first is normal pressure water supply, such as water in containers such as extraction barrels, basins and the like, in this case, after a water filling port 1 is communicated with a water source, a self-priming booster pump 4 needs to be opened, a first valve 3 is closed, a water supply main valve 10 and a second valve 5 are opened, and under the action of the self-priming booster pump 4, water sequentially passes through the water filling port 1, a filter 2, the self-priming booster pump 4 and the second valve 5 and then enters a clear water bag 7; the second is pressure water supply, such as water in a tap water pipe, in this case, the water itself has pressure, after the water filling port 1 is communicated with a water source, the water supply main valve 10 and the first valve 3 need to be opened, the second valve 5 needs to be closed, and the water enters the clean water bag 7 after passing through the water filling port 1, the water supply main valve 10 and the first valve 3 in sequence. When the purified water is prepared, the self-absorption booster pump 4 needs to be started, the first valve 3 is started, the second valve 5 and the water supply main valve 10 are closed, water in the clean water tank sequentially passes through the first valve 3, the self-absorption booster pump 4 and the reverse osmosis membrane assembly 6, after reverse osmosis filtration, the purified water enters the purified water bag 8, and wastewater enters the clean water bag 7, so that the preparation of the purified water is completed. This kind of scheme has not only solved "need two pumps, with high costs" technical problem, need not pass through reverse osmosis when intaking in clear water bag 7 moreover, has ensured water supply efficiency, and clear water bag 7 is intake simultaneously and is provided with two kinds of states of ordinary pressure intaking and pressure intaking, can adapt to the different situation of intaking, and is more convenient.

As a further improvement of the above technical solution, a first water level sensor is arranged in the clean water bag 7, a second sensor is arranged in the clean water bag 8, the water filling port 1 is provided with a normal pressure water supply switch and a pressure water supply switch, the first valve 3 is a normally open solenoid valve, and the second valve 5 and the main water supply valve 10 are both normally closed solenoid valves; when the normal pressure water supply switch is turned on, the main water supply valve 10, the self-priming booster pump 4 and the second valve 5 are controlled to be opened, and the first valve 3 is controlled to be closed; when the pressure water supply switch is turned on, the main water supply valve 10 is controlled to be opened; the water level sensor also comprises a buzzer, wherein the buzzer receives a signal of the first water level sensor and sounds an alarm when the clear water bag 7 is full of water; the automatic water level control system is characterized by further comprising a central controller, wherein the central controller receives signals of the first water level sensor and the second water level sensor, controls the self-suction booster pump 4 to be started when the water levels of the clean water bag 7 and the purified water bag 8 meet the set requirement, and controls the self-suction booster pump 4 to be closed when the purified water bag 8 is full of water. The normal-pressure water supply switch and the pressure water supply switch need to be manually opened and manually closed when the buzzer alarms. When adopting pressure water supply, the user with the water source with fill port 1 well communicate, press the pressure water supply switch, supply water main valve 10 and open, first valve 3 keeps the open mode, second valve 5 keeps the closed condition, begin to intake, when first level sensor detects that clear water bag 7 is full of water, give buzzer, the buzzer is alert and sounded, the manual work is closed pressure water supply switch, supply water main valve 10 and resume closed condition. When normal pressure water supply is adopted, a user well communicates a water source with the water filling port 1, the normal pressure water supply switch is pressed, the water supply main valve 10, the self-priming booster pump 4 and the second valve 5 are opened, the first valve 3 is closed, water starts to enter under the action of the self-priming booster pump 4, when the first water level sensor detects that the clear water bag 7 is full of water, a signal is transmitted to the buzzer, the buzzer sounds, the normal pressure water supply switch is manually closed, the water supply main valve 10 and the second valve 5 recover a closed state, and the first valve 3 recovers an open state. When the central controller receives signals of the first water level sensor and the second water level sensor, the self-suction booster pump 4 is controlled to be started when the water levels of the clear water bag 7 and the purified water bag 8 meet the set requirements, water in the clear water bag 7 sequentially passes through the first valve 3, the self-suction booster pump 4 and the reverse osmosis assembly 6 under the action of the self-suction booster pump 4, purified water enters the purified water bag 8, waste water enters the clear water bag 7, the self-suction booster pump 4 is controlled to be closed when the purified water bag 8 is full of water, and reverse osmosis filtration is stopped. The water level setting requirements of the clean water bag 7 and the pure water bag 8 are as follows: the clear water bag 7 has water, but the pure water bag 8 has water shortage. There are two special cases here: the first is that the purified water meets the set requirement of preparation when supplying water under pressure, and in this case, the water passing through the filter 2 directly passes through the self-priming booster pump 4 for reverse osmosis without being extracted from the clean water bag 7; the second is that the pure water meets the set requirement of preparation when supplying water under normal pressure, because the second valve 5 is in the open state, the water passing through the self-priming booster pump 4 can not reach the pressure required by reverse osmosis, at this moment, the pure water can not be prepared, and the water pumped by the self-priming booster pump 4 enters the clean water bag 7 preferentially. The purified water preparation process is automatically completed, the efficiency is greatly improved, the manpower is saved, and the development trend of the water supply system of the motor home is realized.

Further, the output pipeline 9 of the clean water bag 7 is communicated with the output pipeline 9 of the pure water bag 8 through an emergency valve 12. At ordinary times, the valve is closed to isolate two water supply systems, and the valve can be opened under special emergency conditions to solve the problem that a certain path of water is insufficient, for example, when a bath is in use, the water in the water bag 7 is deficient, and when the water supply system can not work, the valve can be opened to temporarily solve the problem by purified water. Preferably, the emergency valve 12 is a manual valve or a solenoid valve.

Preferably, the primary filter 2 is an ultrafiltration device, so as to further ensure the water quality.

Further, the water terminal position department of the output pipeline 9 of the purified water bag 8 is provided with a coconut shell activated carbon filter 13 to the purified water taste is debugged in the arrangement, and the filtration of the last time is carried out simultaneously to ensure the drinking safety of the purified water.

Specifically, an output pipeline 9 of the clear water bag 7 is connected with a clear water output booster pump 14, clear water is sent to each water using terminal through the clear water output booster pump 14, a branch pipeline is arranged at the water outlet end of the clear water output booster pump 14 to send the clear water to a heater 15, and hot water is sent to each water using terminal through the heater 15; an output pipeline 9 of the purified water bag 8 is connected with a purified water output booster pump 16, and the purified water is sent to each water using terminal through a pipeline.

Through the technical scheme, the high-capacity water production and water storage can be realized, the chance of pollution of water stored in the vehicle can be effectively avoided, the safe, efficient and smooth purified water application of a user can be thoroughly met, and the water supply system is the best technical scheme of the current water supply system for the motor home.
