Technical Field

The invention relates to a glass water anti-freezing system and a vehicle comprising the same.

Background

The glass water is widely applied to the quick decontamination and bright cleaning of various glasses such as automobile glass, rearview mirrors, household glass, office glass, door and window glass, decorative glass and the like. For vehicles, the temperature in some areas may drop below 0 ℃ in winter. In this case, if the glass water of the vehicle is not frozen, the glass water is solidified/frozen into a block shape and becomes large in volume after the temperature of the air is lowered, so that the glass water storage container is easily burst.

In addition, when the glass water is frozen into a block, if the driver unknowingly opens the glass water switch, the motor of the vehicle is likely to be damaged because the glass water is not released.

In addition, if the glass water freezes, the driver can't use glass water to wash windshield if meeting rainy and snowy weather in the driving process, and this will influence driver's sight to bring the potential safety hazard for driving.

In order to prevent the glass water from being solidified, some drivers add the anti-freezing glass water in winter, but if the glass water is not used up in summer, the glass water in summer and the anti-freezing glass water are mixed.

The freezing point of the common anti-freezing glass water in the market at present is generally about-25 ℃ or-40 ℃, and the anti-freezing is mainly realized by adding glycol with different concentrations. However, if the antifreeze glass water is mixed with summer glass water, the freezing point of the glass water is in an unknown state, and the specific freezing point is related to the concentration of the mixed glycol. After the mixing, even though the glass water is changed in winter, the glass water cannot be guaranteed not to freeze.

In addition, sometimes the purchase of unqualified anti-freezing glass water also causes freezing problems, thereby causing danger or economic loss to the driver.

In order to solve the problem of the frozen glass water, in the prior art, a scheme of adding an antifreezing agent into the glass water to reduce the freezing point of the glass water exists, but the schemes cannot accurately control the amount of the antifreezing agent added into the glass water, so that the problem of overlarge or undersize adding amount of the glass water is possibly caused. It is apparent that if the amount of the antifreeze is excessively small, it is liable to cause a problem of freezing of the glass water, whereas if it is excessively large, it is liable to cause a waste of the antifreeze, which in turn tends to cause a premature exhaustion of the antifreeze, and if it is exhausted prematurely without the driver's knowledge, it is liable to cause an inability to further lower the freezing point of the glass water, which in turn leads to a situation of freezing of the glass water and possible bursting of the glass water storage container.

Disclosure of Invention

An object of the present invention is to solve the above-mentioned problems and/or other disadvantages in the prior art, and more particularly, to provide a glass water freezing prevention system capable of preventing glass water from freezing and a vehicle including the same.

To this end, according to one aspect of the present invention, there is provided a glass water freezing prevention system, comprising:

a glass water storage container for storing glass water;

recording the content of an antifreeze such as ethylene glycol in the glass water storage container, and calculating the freezing point of the glass water in the glass water storage container based on the content of the antifreeze;

comparing the calculated freezing point to an air temperature that will be experienced on the next day; and

and controlling the heating and heat-preserving mechanism to heat and maintain the glass water to a temperature higher than the freezing point in the case that the air temperature to be experienced on the next day is below the freezing point.

Furthermore, the invention can automatically acquire the air temperature which will be experienced by the glass water storage container on the next day through the air temperature acquisition system, and the controller can automatically control the heating and heat-preserving mechanism to heat and keep the glass water to the temperature higher than the freezing point based on the comparison result between the freezing point and the air temperature which will be experienced on the next day, thereby realizing the automatic control of the temperature of the glass water to prevent the temperature of the glass water from being reduced below the freezing point, and therefore, the bursting of the glass water storage container is prevented, so as to further ensure the driving safety of a driver.

Preferably, the glass water freezing prevention system further comprises an antifreeze storage container for storing antifreeze, the antifreeze storage container being openably and closably communicated with the glass water storage container. Thus, the driver can also communicate the antifreeze storage container with the glass water storage container when the antifreeze needs to be added, so as to lower the freezing point of the glass water by adding the antifreeze to the glass water, thereby preventing the glass water from freezing.

Preferably, the antifreeze storage container is in openable and closable communication with the glass water storage container via a flow control valve, the controller being further configured to: when the glass water cannot be heated and maintained to a temperature above the freezing point via the heating and holding mechanism, the flow control valve is controlled to open to feed an amount of antifreeze from the antifreeze storage container into the glass water storage container to lower the freezing point of the glass water below an air temperature that will be experienced on the next day. This further ensures the automatic anti-freezing function of the glass water of the system.

Preferably, the controller is further configured to calculate an amount of antifreeze to be fed from the antifreeze storage container into the glass water storage container based on the following formula:

△T＝Tf*－Tf＝Kf×bB

wherein, Tf is the freezing point of water, Tf is the freezing point of glass water, bB is the molar mass concentration of an antifreezing agent in the glass water, and Kf is the freezing point depression constant or solvent constant of water.

The invention can not only prevent the problem of freezing of glass water caused by adding too little antifreeze agent, but also prevent the problem of premature exhaustion of antifreeze agent caused by adding too much antifreeze agent and can maximally save the consumption of supplemented or added antifreeze agent such as ethylene glycol by accurately calculating and controlling the amount of antifreeze agent to be added.

Preferably, the heating and insulating means includes a heating and insulating layer surrounding the outside of the glass water storage container.

Preferably, the glass water antifreeze system is a glass water antifreeze system for a vehicle having an internal combustion engine and/or a battery, the heating and insulating layer being configured to be able to take residual heat of operation of the internal combustion engine and/or the battery and/or being configured to be able to be electrically heated via the battery.

By adopting the scheme, the temperature of the internal combustion engine or the battery can be reduced, the working waste heat of the internal combustion engine and/or the battery can be recovered, and the energy is saved. In addition, the glass water storage container is heated by the existing equipment of the vehicle, so that a new heating device is not added, and the space and the cost are saved.

Preferably, the air temperature acquiring system comprises a receiving device capable of receiving a weather forecast via a network and a global positioning system for determining the location of the glass water storage container. Thus, the air temperature acquiring system can combine the weather forecast of the next day obtained from a network such as a vehicle network with the geographical position where the vehicle is located determined from the global positioning system to obtain the air temperature to be experienced the next day at the geographical position.

Preferably, the antifreeze agent is ethylene glycol or alcohol.

Drawings

The objects, advantages and features according to the invention will become more apparent in the following detailed description of an embodiment thereof, given by way of non-limiting example with reference to the accompanying drawings, in which:

FIG. 1 shows a schematic view of a glass water antifreeze system according to one embodiment of the present invention.

Detailed Description

FIG. 1 illustrates a glass water antifreeze system, such as may be used in a vehicle, according to one embodiment of the present invention, which may include: a glass water storage container 1 such as a glass kettle for storing glass water; a heating and heat-insulating mechanism (e.g., a heating and heat-insulating layer provided outside the molten glass storage container) for heating and heat-insulating the molten glass storage container 1; and an air temperature acquisition system for determining an air temperature that will be experienced the next day at a location where the glass water storage container is located. Preferably, the air temperature obtaining system may comprise receiving means able to receive a weather forecast via a network of vehicles and a global positioning system GPS for determining the location of the glass-water storage container 1 or vehicle, whereby the air temperature obtaining system is able to combine the weather forecast for the next day obtained from the network of vehicles with the geographical location of the vehicle determined from the global positioning system to obtain the air temperature that will be experienced the next day at the geographical location.

The glass water antifreeze system also includes a controller, such as a vehicle control unit, which may be configured to:

recording the content of an antifreeze such as ethylene glycol in the glass water storage container, and calculating the freezing point of the glass water in the glass water storage container 1 based on the content of the existing antifreeze in the glass water storage container 1;

comparing the calculated freezing point to an air temperature that will be experienced on the next day; and

and controlling the heating and heat-preserving mechanism to heat and maintain the glass water to a temperature higher than the freezing point in the case that the air temperature to be experienced on the next day is below the freezing point.

Further, the present invention can automatically acquire the air temperature that the vehicle or the glass water storage container 1 is located at, on the next day, by the air temperature acquisition system, and can automatically control the heating and warming mechanism to heat and maintain the glass water to a temperature higher than the freezing point, based on the freezing point and based on the air temperature that will be experienced on the next day, by the controller, and allow the system to operate only when the temperature of the glass water is higher than the freezing point, and thereby realize the automatic control of the temperature of the glass water. Therefore, the temperature of the glass water can be prevented from being reduced to be below the freezing point, so that the glass water storage container is prevented from being burst, and the driving safety of a driver is further ensured.

In this embodiment, preferably, the glass water freezing prevention system may further include: an antifreeze storage container 2 or called an auxiliary pot for storing antifreeze; an optional pipe 3 connecting the antifreeze storage container with the glass water storage container; and a valve provided on the pipe 3, the valve being openable and closable to openably communicate the glass water storage container with the antifreeze storage container.

With this embodiment, in the case where the temperature of the glass water in the glass water storage container 1 cannot be heated and maintained to a temperature higher than the freezing point by the heating and insulating mechanism, the driver can also lower the freezing point of the glass water by opening the valve to add an antifreeze to the glass water, thereby preventing the glass water from freezing.

Of course, it is conceivable that the glass water storage container 1 and the antifreeze storage container 2 may not be connected by the pipe 3 but may be directly connected, for example, the antifreeze storage container 2 may be placed on the top or side wall of the glass water storage container 1, and a valve may be provided between the glass water storage container 1 and the antifreeze storage container 2, so that when addition of antifreeze is required, the valve may be opened to allow antifreeze to directly enter the glass water storage container 1 from the antifreeze storage container 2, for example, by gravity.

It is also conceivable that a temperature sensor is provided to detect the temperature of the glass water in real time, so that when the detected temperature of the glass water is about to fall to the freezing point, the controller controls the heating and insulating mechanism to heat and insulate the glass water and/or lowers the freezing point of the glass water by heating an antifreeze agent, thereby preventing the glass water from freezing.

Preferably, the valve is a flow control valve 4, so that the antifreeze storage container 2 is openably and closably communicated with the glass water storage container 1 via the flow control valve 4. As such, the controller is further configured to: when the glass water cannot be heated and maintained to a temperature higher than the freezing point via the heating and warming mechanism, the flow control valve 4 is controlled to open to feed an amount of antifreeze from the antifreeze storage container 2 into the glass water storage container 1, thereby lowering the freezing point of the glass water below the air temperature that will be experienced on the next day. In this way, the driver can do nothing manually, and the glass water antifreeze system can be automatically operated to adjust the concentration of the antifreeze such as ethylene glycol in the glass water, which further ensures the automatic antifreeze function of the glass water of the system.

Of course, the controller may also control the opening degree of the flow control valve 4 according to the demand to control the rate of the antifreeze entering the glass water storage container 1.

Preferably, the controller is further configured to calculate the amount of antifreeze to be fed from the antifreeze storage container into the glass water storage container 1 based on the following formula:

△T＝Tf*－Tf＝Kf×bB

wherein, Tf is the freezing point of pure solvent water, Tf is the freezing point of the glass aqueous solution, bB is the molarity of solute B, i.e. the antifreeze, in the glass aqueous solution, and Kf is the freezing point depression constant or solvent constant of water (the numerical value is only related to the property of the solvent), i.e. Kf is 1.86.

For example, in the case of using ethylene glycol as an antifreeze and when the freezing point of glass water is lowered to-20 ℃ in advance, the amount of ethylene glycol to be added to glass water calculated by the formula is as follows:

0-(-20)＝20＝Kf×bB＝1.86×bB

bB＝20/1.86＝10.75mol/kg

thus, the freezing point can be lowered to-20 ℃ by adding 10.75mol of ethylene glycol to one kilogram of water.

Thus, the invention can not only prevent the problem of freezing of the glass water caused by too small amount of added antifreeze agent, but also prevent the problem of premature exhaustion of the antifreeze agent caused by too large amount of added antifreeze agent, which can lead to further decrease of the freezing point of the glass water and thus to freezing of the glass water and possible bursting of the glass water storage container 1, by accurately calculating and controlling the amount of the antifreeze agent to be added.

In the present embodiment, preferably, the heating and heat insulating mechanism such as the heating and heat insulating layer may be configured to take residual heat of operation of an internal combustion engine and/or an electric vehicle battery of the vehicle and/or configured to be heated by being powered via the electric vehicle battery.

By adopting the scheme, the temperature of the internal combustion engine or the battery can be reduced, the working waste heat of the internal combustion engine and/or the battery can be recovered, and the energy is saved. In addition, the glass water storage container is heated by the existing equipment of the vehicle, so that a new heating device is not added, and the space and the cost are saved.

Although the above description has been directed to the use of the glass water antifreeze system in a vehicle, it should be understood that the glass water antifreeze system may be used in other applications, such as in other vehicles, such as aircraft.

Further, although in the above-described embodiment, the freezing point of the glass water is lowered by adding the antifreeze to the glass water by opening the valve only in the case where the temperature of the glass water storage container 1 cannot be heated and maintained to a temperature higher than the freezing point by the heating and keeping mechanism, it is understood that the antifreeze may be added to the glass water first to lower the freezing point of the glass water and the temperature of the glass water may be heated and maintained to a temperature higher than the freezing point by the heating and keeping mechanism when the antifreeze content is too low or exhausted. Of course, the heating and the heat-preserving of the heating and heat-preserving mechanism can be performed simultaneously with the addition of the antifreeze, which falls within the scope of the present invention.

Of course, it is also contemplated that while the above embodiments each include a heating and holding mechanism, it is contemplated that the glass water antifreeze system may not include the heating and holding mechanism, such that the glass water antifreeze system may lower the freezing point of glass water by simply adding antifreeze to the glass water.

Further, although the above embodiments are each implemented for the air temperature that will be experienced the next day of the geographic location where the vehicle is located, it is contemplated that the air temperature acquisition system may acquire air temperatures for any time period in the future, such as 72 hours in the future, 48 hours in the future, 24 hours in the future, 12 hours in the future, etc., and the controller controls the heating and warming mechanism to heat and warm and/or controls the addition of antifreeze based on the air temperatures that will be experienced during the determined future time period.

Further, it should be understood that the antifreeze agent of the present invention can be any suitable antifreeze agent, which is not limited to ethylene glycol.

It will be clear that various modifications and/or improvements and/or combinations, which are obvious to a person skilled in the art, can be made to the many different embodiments of the invention described above without departing from the scope of the invention as defined by the appended claims.
