冬天行车，挡风玻璃上不可避免地会遇到结霜落雪的情况。对于驾驶车辆的驾驶员来讲，不仅仅会影响驾驶视野，更可能会造成驾导致严重的安全事故。由此可见，去除霜雪非常必要。In winter driving, the windshield will inevitably encounter frost and snow. For the driver of the vehicle, not only will it affect the driving horizon, but it will also cause a serious safety accident. It can be seen that it is necessary to remove frost and snow.
如图1所示，本实施例提供的车辆挡风玻璃除霜除污***，包括：供液装置、 加热装置和雨刷器100；供液装置通过管道200与雨刷器100连接，雨刷器100上开设有与管道200连通的出水孔101；加热装置设置于管道200上，用于对清洁液体加热。As shown in FIG. 1 , the vehicle windshield defrost and decontamination system provided by the embodiment includes: a liquid supply device, The heating device and the wiper 100 are connected to the wiper 100 through a pipe 200. The wiper 100 is provided with a water outlet hole 101 communicating with the pipe 200. The heating device is disposed on the pipe 200 for heating the cleaning liquid.
雨刷器100是安装在车辆挡风玻璃上的重要附件，其作用即是扫除挡风玻璃上妨碍视线的雨雪和尘土，对于行车安全具有重要的作用。The wiper 100 is an important accessory mounted on the windshield of the vehicle, and functions to remove rain, snow and dust on the windshield that obstruct the line of sight, and plays an important role in driving safety.
现在的雨刷器100都基本实现了电机驱动，一般由刮水刷臂、刮水刷片总成、刷片102、刷片支座、驱动杆系、减速机构、电动机、开关等组成。在未使用状态下，雨刷器100的刷片102被刮水刷臂压靠在挡风玻璃外表面上。在使用时，启动开关，电动机驱动减速机构旋转，进而驱动杆系作往复运动，带动刮水刷臂和刷片102左右摆动，实现对挡风玻璃的刮刷运动。Nowadays, the wiper 100 basically realizes the motor drive, and generally consists of a wiper brush arm, a wiper brush assembly, a brush 102, a brush holder, a drive rod system, a speed reduction mechanism, a motor, a switch and the like. In the unused state, the brush 102 of the wiper 100 is pressed against the outer surface of the windshield by the wiper arm. In use, the switch is activated, the motor drives the speed reduction mechanism to rotate, and the drive rod is reciprocated to drive the wiper brush arm and the brush piece 102 to swing side to side to realize the wiping motion of the windshield.
由于霜雪其特殊的物性，在去除的时候都会比较麻烦。虽然雨刷器100可以实现部分的除霜除污功能，但是需要雨刷器100长时间反复刮刷，费时费力。Due to the special physical properties of frost and snow, it will be more troublesome to remove. Although the wiper 100 can realize a partial defrost and decontamination function, it is time-consuming and laborious to require the wiper 100 to repeatedly scrape for a long time.
如图2-4所示，本实施例中，雨刷器100开设有出水孔101，该出水孔101与管道200连通，供液装置中的清洁液体通过管道200从出水孔101中喷出作用在车辆的挡风玻璃上。该清洁液体在管道200的输送过程中被加热装置加热，喷射到挡风玻璃上，其较高的温度可以迅速将附着在挡风玻璃上的雪霜融化。其后，雨刷器100作往复运动，将融化后的雪霜的水以及清洁液体一起刷下，经由车辆的排出通道排出。As shown in FIG. 2-4, in the present embodiment, the wiper 100 is provided with a water outlet hole 101, and the water outlet hole 101 communicates with the pipe 200, and the cleaning liquid in the liquid supply device is ejected from the water outlet hole 101 through the pipe 200. On the windshield of the vehicle. The cleaning liquid is heated by the heating device during the conveyance of the pipe 200 and sprayed onto the windshield, and its higher temperature can quickly melt the snow frost attached to the windshield. Thereafter, the wiper 100 reciprocates, and the melted snow frost water and the cleaning liquid are brushed together and discharged through the discharge passage of the vehicle.
经过加热装置加热的清洁液体会有更好的清洁能力，除污效果更佳，在对挡风玻璃进行除霜操作的同时进行除污操作，使挡风玻璃回复干净透亮。The cleaning liquid heated by the heating device has better cleaning ability, better decontamination effect, and decontamination operation while performing defrosting operation on the windshield, so that the windshield is clean and transparent.
一般情况下，水作为一种常见的溶液可以作为清洁液体来使用，经加热的热水可以达到除霜除污的效果。In general, water as a common solution can be used as a cleaning liquid, and the heated hot water can achieve the effect of defrosting and decontaminating.
为了增强除霜除污的效果，还可以采用玻璃水作为清洁液体。玻璃水是车辆挡风玻璃清洗剂的俗称，属于车辆使用中的易耗品。In order to enhance the effect of defrost and decontamination, glass water can also be used as the cleaning liquid. Glass water is a common name for vehicle windshield cleaners and is a consumable item used in vehicles.
玻璃水主要由水、酒精、乙二醇、缓蚀剂以及多种表面活性剂组成，具有去污、房东、抗静电、防腐蚀等功能。其中，酒精、乙二醇可以显著降低液体的冰点，从而起到防冻的作用，可以快速溶解雪霜。而表面活性剂通常具有润湿、渗透、增溶等功能，从而起到清洁除污的作用。Glass water is mainly composed of water, alcohol, ethylene glycol, corrosion inhibitor and various surfactants. It has functions such as decontamination, landlord, antistatic and anti-corrosion. Among them, alcohol and ethylene glycol can significantly reduce the freezing point of the liquid, thereby preventing the freezing effect, and can quickly dissolve the snow frost. Surfactants usually have functions such as wetting, permeation, solubilization, etc., so as to clean and decontaminate.
具体地，雨刷器100包括两个平行设置的刷片102，两个刷片102之间设置有用于喷洒清洁液体的渗水板103，该渗水板103与两个刷片102共同围成中空腔体。Specifically, the wiper 100 includes two brush plates 102 disposed in parallel. A water-permeable plate 103 for spraying a cleaning liquid is disposed between the two brush plates 102. The water-permeable plate 103 and the two brush plates 102 together form a hollow cavity. .
雨刷器100的刷片102就如同紧紧贴合挡风玻璃表面的扫帚，由刮水刷臂带动 其在挡风玻璃表面来回移动，通过反复摩擦刮掉挡风玻璃表面的水渍、污垢以及雪霜。The brush 102 of the wiper 100 acts like a broom that closely fits the surface of the windshield, and is driven by the wiper arm. It moves back and forth on the windshield surface, scraping off the water, dirt and snow frost on the windshield surface by repeated friction.
刷片102的材质一般选择橡胶，因为橡胶具有优良的回弹性、绝缘性、隔水性以及可塑性，是最适合制作刷片102的材料。早期的刷片102大多选用天然橡胶，天然橡胶的综合物理机械性能优于其他的橡胶组成，加工性能好，但是耐热、耐氧化以及耐油性能较差。随着技术的进步，合成橡胶开始广泛应用。合成橡胶具有优越的耐氧化、抗臭氧和抗侵蚀的能力，在保证刮水性能的同时，还增加了刷片102的使用寿命。根据化工工艺以及添加剂的不同，刮片的质量好坏区分比较明显，质量优的刷片102刮刷后很干净，在反复刮刷的过程中组里也较小，无噪音无振动。The material of the brush sheet 102 is generally selected from rubber. Since rubber has excellent resilience, insulation, water repellency and plasticity, it is the material most suitable for the production of the brush sheet 102. Most of the early brush blades 102 were made of natural rubber. The comprehensive physical and mechanical properties of natural rubber were superior to those of other rubbers. The processing performance was good, but the heat resistance, oxidation resistance and oil resistance were poor. With the advancement of technology, synthetic rubber has begun to be widely used. Synthetic rubber has superior oxidation resistance, ozone resistance and erosion resistance, and increases the service life of the brush sheet 102 while ensuring the water wiping performance. According to different chemical processes and additives, the quality of the blade is clearly distinguished. The brush 102 with excellent quality is very clean after wiping. In the process of repeated wiping, the group is also small, no noise and no vibration.
在选择刷片102的材质时，还需要考虑橡胶的硬度。当橡胶硬度过大时，会导致刷片102的胶条刃口与挡风玻璃的表面的角度过大，进而增大了雨刷器100在工作中产生抖动的隐患。反之，当橡胶的硬度过小时，雨刷器100在工作中的力度不够大，存在漏刮和刮不干净的隐患。When selecting the material of the brush sheet 102, it is also necessary to consider the hardness of the rubber. When the rubber hardness is too large, the angle between the strip edge of the brush 102 and the surface of the windshield is too large, thereby increasing the risk of the wiper 100 being shaken during operation. On the contrary, when the hardness of the rubber is too small, the strength of the wiper 100 in the work is not large enough, and there is a hidden danger that the wiper blade and the scraping are not clean.
雨刷器100在工作中，通过刮水刷臂向刷片102均匀施加垂直压力，使刷片102胶条的刃口垂直于车辆挡风玻璃的曲面，并与其贴合。During the operation of the wiper 100, the vertical pressure is uniformly applied to the brush 102 by the wiper arm, so that the edge of the strip of the brush 102 is perpendicular to the curved surface of the windshield of the vehicle and is attached thereto.
雨刷器100一般分为有骨雨刷和无骨雨刷。有骨雨刷即传统雨刷，其工作原理是通过骨架上的若干支撑点把刷片102压在挡风玻璃上，使刷片102上的各个支撑点的压力平均。但是由于其结构关系，不可能使得刷片102与挡风玻璃完美贴合，造成刮不干净、刷片102易磨损、噪音大等问题。而无骨雨刷依靠一整根导力条老分散压力，刷片102的各个部分受力均匀，可以减少水痕的产生，达到更好的刮刷效果。The wiper 100 is generally classified into a bone wiper and a boneless wiper. A bone wiper, that is, a conventional wiper, works by pressing the brush 102 against the windshield through a plurality of support points on the skeleton to average the pressure of each support point on the brush 102. However, due to its structural relationship, it is impossible to make the brush sheet 102 and the windshield fit perfectly, resulting in problems such as dirty scratching, easy wear of the brush sheet 102, and high noise. The boneless wiper relies on a whole force of the entire force distribution bar, and the various parts of the brush piece 102 are evenly stressed, which can reduce the generation of water marks and achieve a better scratching effect.
本实施例中，雨刷器100设置有两个平行的刷片102，在两个刷片102之间设置有渗水板103。该渗水板103和两个刷片102围成一个中空腔体。管道200的一端与供液装置连通，另一端一直延伸至雨刷器100与中空腔体连通。经由管道200输送到雨刷器100的清洁液体进入该腔体，从渗水板103排出。此时，出水孔101设置在渗水板103上。In the present embodiment, the wiper 100 is provided with two parallel brush blades 102, and a water seepage plate 103 is disposed between the two brush blades 102. The water seepage plate 103 and the two brush sheets 102 enclose a hollow cavity. One end of the pipe 200 communicates with the liquid supply device, and the other end extends until the wiper 100 communicates with the hollow cavity. The cleaning liquid delivered to the wiper 100 via the duct 200 enters the cavity and is discharged from the water seepage plate 103. At this time, the water outlet hole 101 is provided on the water seepage plate 103.
供液装置中的清洁液体由管道200输送至雨刷器100，清洁液体进入中The cleaning liquid in the liquid supply device is conveyed by the pipe 200 to the wiper 100, and the cleaning liquid enters
渗水板103的形状应与两个平行设置的刷片102形成的空间相适应，且渗水板103与刷片102连接的位置不在刷片102与挡风玻璃接触的端部，即不与挡风玻璃接触且与之存在一定间隙。这是因为，刷片102在工作中由于橡胶的弹性会产生变形，若渗水板103设置在刷片102与挡风玻璃接触的端部，雨刷器100工作时，刷 片102产生变形，渗水板103与挡风玻璃接触，一则影响雨刷器100正常工作，二则会对渗水板103造成损坏。The shape of the water seepage plate 103 should be adapted to the space formed by the two parallelly disposed brush blades 102, and the position where the water seepage plate 103 and the brush blade 102 are connected is not at the end of the brush blade 102 contacting the windshield, that is, not being shielded from the wind. The glass is in contact with and has a certain gap. This is because the brush piece 102 is deformed due to the elasticity of the rubber during operation. If the water seepage plate 103 is disposed at the end of the brush piece 102 that is in contact with the windshield, when the wiper 100 is in operation, the brush The sheet 102 is deformed, and the water seepage plate 103 is in contact with the windshield, one affects the normal operation of the wiper 100, and the other causes damage to the water seepage plate 103.
由于渗水板103沿着两个刷片102之间的间隙设置，其形状应该为狭长的面。设置在渗水板103上的多个出水孔101优选地沿着渗水板103的长度方向单排设置。并且，为了雨刷器100在工作中能够均匀地喷洒清洁液体到挡风玻璃表面，出水孔101沿着渗水板103的长度方向均匀延伸设置，布满整个渗水板103。Since the water seepage plate 103 is disposed along the gap between the two brush sheets 102, its shape should be an elongated face. The plurality of water outlet holes 101 provided on the water seepage plate 103 are preferably arranged in a single row along the longitudinal direction of the water seepage plate 103. Moreover, in order to uniformly spray the cleaning liquid onto the windshield surface during operation of the wiper 100, the water outlet hole 101 is evenly extended along the longitudinal direction of the water seepage plate 103 to cover the entire water seepage plate 103.
需要说明的是，本实施例中的出水孔101的形状设置为圆形，但并不仅限于圆形，也可以是正方形、菱形以及其他形状，圆形只是一种优选方案。It should be noted that the shape of the water outlet hole 101 in the present embodiment is circular, but it is not limited to a circular shape, but may be a square shape, a rhombus shape, and the like. The circular shape is only a preferred embodiment.
本实施例中的供液装置包括水泵300和用于储存清洁液体的水箱400，水箱400与所述管道200的一端连接。The liquid supply device in this embodiment includes a water pump 300 and a water tank 400 for storing a cleaning liquid, and the water tank 400 is connected to one end of the pipe 200.
具体地，水箱400可以直接采用车辆中存储玻璃水的水箱，经济且方便。Specifically, the water tank 400 can directly adopt a water tank in which glass water is stored in the vehicle, which is economical and convenient.
水泵300是输送液体或者使液体增压的机械，它将发动机的机械能或者其他外部能力传送给液体，使液体的能量增加。The water pump 300 is a machine that delivers or pressurizes the liquid, and transmits mechanical energy or other external capabilities of the engine to the liquid to increase the energy of the liquid.
水箱400一般放置在车辆的发动机位置附近，相较于挡风玻璃的位置处于低处。水泵300的作用即将存储在水箱400中的清洁液体抽取并输送到位于雨刷器100中由两个刷片102和渗水板103构成的中空腔体中，清洁液体再经由渗水板103上的出水孔101排出喷射到挡风玻璃上。The water tank 400 is generally placed near the engine position of the vehicle, at a lower position than the position of the windshield. The function of the water pump 300 extracts and transports the cleaning liquid stored in the water tank 400 to the hollow body formed by the two brush blades 102 and the water seepage plate 103 in the wiper 100, and the cleaning liquid passes through the water outlet hole on the water seepage plate 103. The 101 discharge is sprayed onto the windshield.
需要说明的是，水泵300设置在水箱400与加热装置之间的管道200部分上，也就是说，管道200的一端连接水箱400，从水箱400开始，沿着管道200依次设置水泵300、加热装置，管道200的另一端连接雨刷器100。It should be noted that the water pump 300 is disposed on the portion of the pipe 200 between the water tank 400 and the heating device, that is, one end of the pipe 200 is connected to the water tank 400, and the water pump 300 and the heating device are sequentially disposed along the pipe 200 from the water tank 400. The other end of the duct 200 is connected to the wiper 100.
具体地，加热装置以环绕的方式设置于水泵300与雨刷器100的之间的管道200上，即所述管道200穿过加热装置。Specifically, the heating device is disposed in a circumferential manner on the duct 200 between the water pump 300 and the wiper 100, that is, the duct 200 passes through the heating device.
将加热装置以环绕的方式设置在管道200上，可以实现在短时间内将管道200内的清洁液体加热的目的。By arranging the heating means in a surrounding manner on the duct 200, it is possible to heat the cleaning liquid in the duct 200 in a short time.
需要说明的是，加热装置沿着管道200中清洁液体的输送方向设置在水泵300的后方。这样设置的原因是，加热装置将清洁液体加热后，清洁液体温度升高，若此时再经过水泵300，温度较高的清洁液体相较于普通的清洁液体会对水泵300产生更强的损害，会导致水泵300的使用寿命缩减。It should be noted that the heating device is disposed behind the water pump 300 along the conveying direction of the cleaning liquid in the duct 200. The reason for this arrangement is that after the heating device heats the cleaning liquid, the temperature of the cleaning liquid rises. If the water pump 300 passes again at this time, the cleaning liquid having a higher temperature will cause more damage to the water pump 300 than the ordinary cleaning liquid. This will result in a reduction in the service life of the water pump 300.
具体地，加热装置包括电加热器500。该电加热器500为管状，套设在管道200上。Specifically, the heating device includes an electric heater 500. The electric heater 500 is tubular and sleeved on the pipe 200.
电加热器500是一种普遍使用的电加热设备，主要用于对流动的液态、气态介 质进行升温、保温或者加热操作。当需要被加热的介质在压力作用下通过电加热器500的加热腔，该介质由于流体热力学原理均匀地带走电热元件工作中产生的巨大热量，从而该介质达到被加热的目的。本实施例中，需要被加热的介质即经由管道200输送到电加热器500的清洁液体。 Electric heater 500 is a commonly used electric heating device, mainly used for the flow of liquid and gaseous medium. The temperature is raised, kept warm or heated. When the heated medium needs to pass through the heating chamber of the electric heater 500 under pressure, the medium uniformly takes away the huge heat generated in the operation of the electric heating element due to the fluid thermodynamic principle, so that the medium reaches the purpose of being heated. In the present embodiment, the heated medium, that is, the cleaning liquid that is delivered to the electric heater 500 via the duct 200, is required.
根据电能转换方式的不同，电加热器500的电加热方式一般分为电阻加热、感应加热、电弧加热、电子束加热、红外线加热和介质加热等。The electric heating method of the electric heater 500 is generally classified into resistance heating, induction heating, arc heating, electron beam heating, infrared heating, and medium heating, depending on the manner of electric energy conversion.
本实施例中电加热器500采用的是电阻加热，其电热元件为电阻丝。In the embodiment, the electric heater 500 is made by resistance heating, and the electric heating element is a resistance wire.
电阻加热是利用电流的焦耳效应将电能转化为热能以加热物体。一般分为直接电阻加热和间接电阻加热。前者的电源电压直接加到被加热物体上，当有电流通过，被加热物体本身便发热。可直接电阻加热的物体必须是导体且具有较高的电阻率。间接电阻加热需要由专门的金属或者合金制成发热元件，由发热元件产生热能，通过辐射、对流和传导等方式传输到被加热物体上。由于被加热物体与发热元件分为两部分，因此被加热物体的种类不受限制，且操作简便。Resistance heating uses the Joule effect of current to convert electrical energy into thermal energy to heat an object. Generally divided into direct resistance heating and indirect resistance heating. The former's power supply voltage is directly applied to the object to be heated, and when a current is passed, the heated object itself heats up. Objects that can be directly resistively heated must be conductors and have a high electrical resistivity. Indirect resistance heating requires a special metal or alloy to be used as a heating element. Thermal energy is generated by the heating element and transmitted to the object to be heated by radiation, convection and conduction. Since the object to be heated and the heating element are divided into two parts, the type of the object to be heated is not limited, and the operation is simple.
需要说明的是，本实施例中的电加热器500外部设置有引出片，该引出片内与电加热器500内部的电阻丝连接、外与外部的电源连接。其中，引出片与电源之间由导线连接。引出片相对于电加热器500的位置不作限制。It should be noted that the electric heater 500 in the present embodiment is provided with a lead piece which is connected to the electric resistance wire inside the electric heater 500 and externally to the external power source. Wherein, the lead piece and the power source are connected by wires. The position of the lead piece relative to the electric heater 500 is not limited.
并且，电阻丝在电加热器500内部的排布方式不作限制，可以环绕管道200设置，也可以沿管道200延伸方向蛇形迂回设置。但是，排布方式优选使得电阻丝之间的间隔相同，以取得对清洁液体加热均匀的效果。Further, the arrangement of the electric resistance wires inside the electric heater 500 is not limited, and may be provided around the duct 200 or may be arranged in a serpentine direction along the extending direction of the duct 200. However, the arrangement is preferably such that the intervals between the electric resistance wires are the same to obtain a uniform heating effect on the cleaning liquid.
本实施例还包括控制装置，该控制装置分别与水泵300和加热装置电连接。This embodiment also includes a control device that is electrically coupled to the water pump 300 and the heating device, respectively.
该控制装置用来控制水泵300以及电加热器500的动作，需要说明的是，水泵300和电加热器500的控制电路是分别独立设置的，可以独立对水泵300以及电加热器500进行控制。The control device is used to control the operation of the water pump 300 and the electric heater 500. It should be noted that the control circuits of the water pump 300 and the electric heater 500 are separately provided, and the water pump 300 and the electric heater 500 can be independently controlled.
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。 Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, and are not intended to be limiting; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that The technical solutions described in the foregoing embodiments may be modified, or some or all of the technical features may be equivalently replaced; and the modifications or substitutions do not deviate from the technical solutions of the embodiments of the present invention. range.
