Description

一种节水省电省时的电热水龙头Water-saving, electricity-saving and time-saving electric faucet

技术领域Technical field

本实用新型涉及一种水龙头，尤其涉及一种即热式的电热水龙头。The utility model relates to a faucet, in particular to an instant electric faucet.

背景技术Background technique

现有技术中最常见的生活用水水龙头，包括水龙头壳体，壳体内具有热水进口、冷水进口和出水口的混水阀芯，或者具有冷水进口、冷水出口和热水进口、热水出口的冷热双阀芯，混水阀芯的出水口或者冷热双阀芯的冷水出口和热水出口与水龙头的出水口连通，壳体上还具有操作机构，操作机构型式有旋扭、手柄等，操作机构与混水阀芯或者冷热双阀芯连接，控制混水阀芯或者冷热双阀芯的进出水情况及混水情况。The most common domestic water faucet in the prior art, including a faucet casing, a mixing valve core having a hot water inlet, a cold water inlet and a water outlet in the casing, or a cold water inlet, a cold water outlet, a hot water inlet, and a hot water outlet. The hot and cold double valve core, the water outlet of the mixing valve core or the cold water outlet and the hot water outlet of the hot and cold double valve core are connected with the water outlet of the faucet, and the operating mechanism is also provided on the casing, and the operating mechanism has the type of knob, handle, etc. The operating mechanism is connected with the mixing valve core or the hot and cold double valve core to control the water inlet and outlet conditions and the mixed water condition of the mixing water valve core or the hot and cold double valve core.

混水阀芯中单柄双联阀芯是生活、生产中最常见的水龙头阀芯，尤其是陶瓷片单柄双联阀芯，已是目前厨房、卫生间中普遍使用的冷热水龙头阀芯。阀芯包括固定片和动片构成的密封片，操作机构为控制动片相对固定片密封滑动的控制柄，固定片上设有冷进水孔、热进水孔和出水孔，动片上设有通道，该通道用以在动片相对固定片密封滑动时连通热进水孔和出水孔，或者冷进水孔和出水孔，或者热进水孔、冷进水孔和出水孔。以抬启式的单柄双联阀芯为例，我国国内的通常操作标准为，控制柄左转至极限位置附近区域为出水孔仅出热水，此时出水孔仅与热进水孔通过通道连通；控制柄右转至极限位置附近区域为出水孔仅出冷水，此时出水孔仅与冷进水孔通过通道连通；而在两者之间则是冷热水混合的混水区域，此时出水孔同时与冷、热进水孔通过通道连通，控制柄越往左旋，冷、热进水比例中热水比例越大，水越热，直至变成纯粹热水；控制柄越往右旋，冷、热进水比例中冷水比例越大，水越冷，直至变成纯粹冷水。而在控制柄左右旋转中，通过上抬控制柄的上抬角度调节此刻的出水流量，角度越大流量越大。The single-handle double spool in the mixing valve core is the most common faucet spool in life and production, especially the single-handle double spool of ceramic sheet. It is the hot and cold water faucet valve commonly used in kitchens and bathrooms. The valve core comprises a sealing piece composed of a fixing piece and a moving piece, and the operating mechanism is a control handle for controlling the sliding sliding of the moving piece relative to the fixed piece. The fixing piece is provided with a cold water inlet hole, a hot water inlet hole and a water outlet hole, and the moving piece is provided with a passage. The passage is configured to communicate the hot water inlet hole and the water outlet hole, or the cold water inlet hole and the water outlet hole, or the hot water inlet hole, the cold water inlet hole and the water outlet hole when the movable piece is sealed and sliding relative to the fixed piece. Taking the single-handle double-spool valve of the lift type as an example, the normal operation standard in China is that the control handle is turned left to the vicinity of the limit position, and only the hot water is discharged from the outlet hole. At this time, the water outlet only passes through the hot water inlet hole. The passage is connected; the right handle is turned to the vicinity of the limit position, and only the cold water is discharged from the outlet hole. At this time, the outlet hole only communicates with the cold inlet hole through the passage; and between the two is a mixed water area where the hot and cold water is mixed. At this time, the water outlet hole communicates with the cold and hot water inlet holes through the passage, and the control handle turns to the left. The proportion of hot water in the cold and hot water inlet ratio is larger, and the hotter the water, until it becomes pure hot water; the handle is turned to the right. The greater the proportion of cold water in the ratio of spin, cold and hot water, the colder the water until it becomes pure cold water. In the left and right rotation of the control handle, the flow rate of the water at the moment is adjusted by the upward lifting angle of the lifting handle, and the larger the angle, the larger the flow rate.

冷热双阀芯也是生活、生产中最常用的水龙头阀芯，相对单柄双联阀芯只有一个操作机构(控制柄或控制旋钮等)，冷热双阀芯具有两个操作机构，分别为控制冷水阀芯的冷水操作机构(控制柄或控制旋钮等)，和控制热水阀芯的热水操作机构(控制柄或控制旋钮等)。冷水阀芯具有冷水进口和冷水出口，冷水从冷水阀芯的冷水进口进从冷水出口出，由冷水阀芯的控制机构控制出水开关和出水量，热水阀芯具有热水进口和热水出口，热水从热水阀芯的热水进口进从热水出口出，由热水阀芯的控制机构控制出水开关和出水量，冷水和热水在水龙头内的汇水口汇合形成混水并最终从水龙头的出水口出水。The hot and cold double valve core is also the most commonly used faucet valve core in life and production. Compared with the single handle double valve core, there is only one operating mechanism (control handle or control knob, etc.). The hot and cold double valve core has two operating mechanisms, respectively A cold water operating mechanism (control lever or control knob, etc.) that controls the cold water valve spool, and a hot water operating mechanism (control lever or control knob, etc.) that controls the hot water spool. The cold water valve core has a cold water inlet and a cold water outlet. The cold water is imported from the cold water inlet of the cold water valve core and exits from the cold water outlet. The control mechanism of the cold water valve core controls the water outlet switch and the water output. The hot water valve core has a hot water inlet and a hot water outlet. The hot water is imported from the hot water of the hot water valve plug into the hot water outlet, and the control mechanism of the hot water spool controls the water outlet switch and the water output. The cold water and the hot water merge at the water inlet in the faucet to form a mixed water and finally Water is discharged from the outlet of the faucet.

不管各种混水阀芯或者冷热双阀芯的不同，对于水龙头整体而言，现有的水龙头混水阀芯或者冷热双阀芯的冷水进口通常直接接常温水(指未经额外加热的自然状态的水，并非特指温度为常温例如25℃的水)，例如自来水，而热水进口则接各种热水水源，通常是各种热水器，比如煤气热水器、天然气热水器、电热水器、太阳能热水器、空气能热水器。Regardless of the difference between various mixing valve cores or hot and cold double valve cores, the faucet mixing valve core or the cold water inlet of the hot and cold double valve core is usually directly connected to normal temperature water (for no additional heating). The water in the natural state does not specifically refer to water at a normal temperature such as 25 ° C. For example, tap water, and the hot water inlet is connected to various hot water sources, usually various water heaters, such as gas water heaters, natural gas water heaters, electric water heaters, Solar water heaters, air energy water heaters.

但现有的水龙头存在以下问题：However, the existing faucets have the following problems:

普通的水龙头，夏天时，气温较高，水龙头的冷水出水温度随之较高，此时直接放冷水体感也是舒适的。同样的，直接放热水时，由于从热水器到水龙头通常具有一段距离，在将该距离内的冷水放掉之前，水龙头出水也一直是冷水，但此时冷水的体感也是舒适的。Ordinary faucets, in summer, the temperature is higher, the chiller's cold water effluent temperature is higher, at this time the direct cold water body feel is also comfortable. Similarly, when directly discharging hot water, since the water heater to the faucet usually has a certain distance, the faucet water is always cold water before the cold water in the distance is discharged, but the cold water is also comfortable.

但到了秋天或者春天，特别是冬天，气温较低，水龙头的冷水出水温度也随之较低，此时直接放冷水体感就很不舒服了，甚至冰冷刺骨无法忍受。同样的，直接放热水，前面一段冷水也是如此。But in the fall or spring, especially in winter, the temperature is lower, and the cold water outlet temperature of the faucet is also lower. At this time, it is very uncomfortable to put the cold water directly into the body, and even the cold and biting can't stand it. Similarly, direct hot water, as well as the previous section of cold water.

相对普通水龙头，现有一些电热水龙头，现有技术中的电热水龙头，包括单进水管(连接冷水管)和双进水管(连接冷水管和热水管)电热水龙头，单手柄操控和双手柄操控电热水龙头，均采用即热式加热方式——水龙头出水与电加热模块的加热同时进行。即热式电热水龙头与由普通水龙头与热水器组成的热水供应***相比，即热式电热水龙头省略了普通水龙头至热水器之间的连接管路，使用热水时，减少了需先从普通水龙头放出连接管路中储存水所造成的水资源浪费，也减少了水龙头关闭热水后储存在连接管路中热水所蕴含的热量损失，并缩短了热水等待时间。但是，电热水龙头所采用的即热式加热方式仍然存在弊病：Compared with ordinary faucets, there are some electric faucets, the electric faucets in the prior art, including single inlet pipes (connecting cold water pipes) and double inlet pipes (connecting cold water pipes and hot water pipes) electric faucets, single handle control and double handle control The electric faucets are all heated by the instant heating method - the faucet effluent and the heating of the electric heating module are simultaneously performed. The hot electric faucet is compared with the hot water supply system consisting of a common faucet and a water heater. The hot electric faucet omits the connecting pipe between the ordinary faucet and the water heater. When using hot water, the first faucet is reduced. The waste of water caused by the storage of water in the connecting pipe is also reduced, and the heat loss contained in the hot water stored in the connecting pipe after the faucet is turned off is reduced, and the waiting time of the hot water is shortened. However, the instant heating method used in electric faucets still has drawbacks:

其一，理论上，虽然即热式电热水龙头实现了出水与加热同时进行，但在实际中，由于热水是冷水吸收热量并累积到一定数量后所形成，所以热水存在滞后，电热水龙头自出水到出热水仍然需要一定的过度时间，此过程中同样存在水资源和能源浪费，浪费只是减少并未根除；First, in theory, although the hot electric faucet realizes the simultaneous discharge of water and heating, in practice, since the hot water is formed by the cold water absorbing heat and accumulating to a certain amount, there is a lag in the hot water, and the electric faucet is self-heating. There is still a certain excess time from the effluent to the hot water. In this process, there is also water and energy waste, and waste is only reduced and not eradicated;

其二，日常生活中常见的洗手或者用口杯接漱口水，通常数秒钟即可完成，但是，目前常用的加热管式电热水龙头出热水等待时间约十多秒，厚膜加热电热水龙头或者裸丝加热电热水龙头等待时间稍短，因此用水者使用热水时的用水体验仍然有待提升。Secondly, the common hand washing in daily life or mouthwash with mouth cup can usually be completed in a few seconds. However, the commonly used heating tube type electric hot water faucet waits for about ten seconds of hot water, thick film heating electric faucet or The bare wire heating electric faucet has a shorter waiting time, so the water experience when the water user uses the hot water still needs to be improved.

即现有技术的即热式电热水龙头，出水与加热实现了同步，但出水与出热水不同步，出热水滞后。而且，现有技术的即热式电热水龙头，出热水需要过渡阶段，此阶段出水由常温升至热水，需要较长时间，需要不断地进水与出水，同时存在水资源和能源的无效损耗。现有技术的即热式电热水龙头费水费电费时。That is, the prior art instant electric hot water faucet realizes synchronization of the effluent and the heating, but the effluent and the hot water are not synchronized, and the hot water lags behind. Moreover, the prior art instant electric faucet needs a transitional stage for the hot water supply. At this stage, the effluent rises from normal temperature to hot water, which takes a long time, requires constant water and water, and has ineffective water resources and energy. loss. The prior art instant electric faucet requires a fee for electricity and electricity.

实用新型内容Utility model content

本实用新型的目的在于：提出一种节水省电省时的电热水龙头，解决现有技术水龙头出水和出热水之间不同步，出热水相对出水滞后，且初始加热方式为“动态升温”，费水费电费时，本申请实现水龙头出水的同时即为热水，且初始加热方式为“静态升温”，能够有效地节水省电省时。The utility model aims to provide a water-saving, electricity-saving and time-saving electric hot water faucet, which solves the problem that the faucet water and the hot water in the prior art are not synchronized, the hot water lags behind the water, and the initial heating mode is “dynamic heating”. "When the water fee is charged, the water supply of the faucet is hot water at the same time, and the initial heating mode is "static heating", which can effectively save water, save electricity and save time.

本实用新型的目的通过下述技术方案来实现：The purpose of the utility model is achieved by the following technical solutions:

一种节水省电省时的电热水龙头，其设有使水龙头出水升温的电加热模块，以及控制该电加热模块启动或停止的控制开关，水龙头出水和电加热模块的加热启动非同步进行，且电加热模块的加热启动在水龙头出水的一段时间之前。The utility model relates to a water-saving, electricity-saving and time-saving electric hot water faucet, which is provided with an electric heating module for heating the faucet water, and a control switch for controlling the start or stop of the electric heating module, and the heating start of the faucet water outlet and the electric heating module are asynchronously performed. And the heating of the electric heating module is started before the faucet is discharged for a period of time.

作为优选的两种实现方式：As two preferred implementations:

方式一：一种节水省电省时的电热水龙头，其设有使水龙头出水升温的电加热模块，以及控制该电加热模块启动或停止的控制开关，控制开关的开启和关闭与外部操作机构控制水龙头出水的开启或关闭各自独立。Method 1: A water-saving, electricity-saving and time-saving electric hot water faucet, which is provided with an electric heating module for heating the faucet water, and a control switch for controlling the start or stop of the electric heating module, controlling the opening and closing of the switch and the external operating mechanism Control the opening or closing of the tap water separately.

方式二：一种节水省电省时的电热水龙头，其设有使水龙头出水升温的电加热模块，以及控制该电加热模块启动或停止的控制开关，还包括与控制开关并联控制电加热模块启动或停止的第二控制开关，第二控制开关为开启后按照预定时间关闭的延时开关，或者为开启后水体温度或者电加热模块温度按照预定温度关闭的温控开关。Method 2: A water-saving, electricity-saving and time-saving electric hot water faucet, which is provided with an electric heating module for heating the faucet water, and a control switch for controlling the start or stop of the electric heating module, and a parallel control electric heating module with the control switch The second control switch that is started or stopped, the second control switch is a time delay switch that is turned off according to a predetermined time after being turned on, or a temperature control switch that is turned off according to a predetermined temperature after the water body temperature or the electric heating module temperature is turned on.

本申请的电热水龙头，涉及一种加热前置技术——先加热，后出水，即启动电加热模块对水龙头内的存水加热一段时间后，水龙头再最终出水。The electric hot water faucet of the present application relates to a heating pre-heating technology - first heating, then discharging water, that is, starting the electric heating module to heat the water in the faucet for a period of time, and then the faucet finally effluent.

第一，对于短时热水使用需求，采用本申请方案，相对现有技术还未获得热水之前已经获得热水，例如：采用加热管的即热式电热水龙头，因为在电加热模块加热的时候，水龙头中水一直处于快进快出地流动状态，水加热到热水状态(比如升温20℃)需要较长时间——自水龙头出水到出热水约需14秒，如果短时热水使用为5秒，整个过程用时19秒，等待时间14秒，加热时长19秒，水龙头出水19秒，如采用加热前置技术方法，因为只需要加热水龙头内的非流动的存水，水加热到热水状态只需很少时间——加热前置6秒，加热前置完成后出水即为热水，短时热水使用5秒，整个过程用时11秒，等待时间6秒，加热时长6秒，水龙头出水5秒(此时加热装置不加热，出水为加热前置产生的热水)。两种方法比较，采用加热前置技术，整个过程用时为58％，等待时间为43％，电热水龙头加热时长(耗电量)为32％，水龙头出水(用水量)为26％。First, for the short-term hot water use demand, the solution of the present application is adopted, and the hot water has been obtained before the hot water has been obtained compared with the prior art, for example, the instant electric hot water faucet using the heating pipe, because the electric heating module is heated. At the time, the water in the faucet is always in a fast-forward and fast-flowing state. It takes a long time for the water to heat up to a hot water state (for example, a temperature rise of 20 ° C) - it takes about 14 seconds from the tap to the hot water, if short-time hot water The use is 5 seconds, the whole process takes 19 seconds, the waiting time is 14 seconds, the heating time is 19 seconds, and the faucet is out of water for 19 seconds. If the heating front technology is used, only the non-flowing water in the faucet needs to be heated, and the water is heated to The hot water state takes only a small amount of time - heating for 6 seconds, after the heating is completed, the water is hot water, short-time hot water is used for 5 seconds, the whole process takes 11 seconds, the waiting time is 6 seconds, and the heating time is 6 seconds. The faucet is discharged for 5 seconds (the heating device is not heated at this time, and the effluent is the hot water generated by heating). Comparing the two methods, the heating front technology is used, the whole process time is 58%, the waiting time is 43%, the electric faucet heating time (power consumption) is 32%, and the faucet water (water consumption) is 26%.

第二，对于长时间热水使用需求，同样的，先进行加热前置6秒后加热前置结束，然后电热水龙头出水开启而正常加热继续进行，使用完毕后再关闭加热和出水(与现有电热水龙头相同)。针对长时间热水使用，加热前置技术在开始阶段缩短了热水等待时间，减少了加热时长(耗电量)和水龙头出水(用水量)，实现了水龙头出水的同时即为热水，在出水以后的后续阶段与现有电热水龙头没有区别。Second, for long-term hot water use demand, the same, first heating for 6 seconds, then heating the front end, then the electric hot water tap water is turned on and normal heating continues, and then turn off the heating and effluent after use (with existing The electric faucet is the same). For long-term hot water use, the heating front-end technology shortens the hot water waiting time at the beginning, reduces the heating time (power consumption) and the faucet water (water consumption), and realizes the hot water when the faucet is discharged. The subsequent stage after the effluent is no different from the existing electric faucet.

作为选择，电加热模块的加热启动后到达预定时间之后水龙头出水，或者电加热模块的加热启动后水体温度或者电加热模块温度到达预定温度之后水龙头出水。该方案中，通过延时控制或温度控制的两种方式，控制电加热模块的“加热前置”的加热时间。Alternatively, after the heating of the electric heating module is started, the faucet is discharged after reaching the predetermined time, or the faucet is discharged after the water body temperature or the electric heating module temperature reaches the predetermined temperature after the heating of the electric heating module. In this solution, the heating time of the "heating front" of the electric heating module is controlled by two methods of delay control or temperature control.

作为进一步选择，电加热模块的加热启动之前还进行温度或时间的判断：当水体温度或者电加热模块温度接近预定温度时，减少电加热模块的加热启动后的预定时间，当水体温度或者电加热模块温度超过预定温度时，停止电加热模块的加热启动；或者电加热模块的加热启动距离上次启动(或者上次加热停止)的间隔时间低于预定间隔时间，减少电加热模块的加热启动后的预定时间或停止电加热模块的加热启动。该方案中，电加热模块的加热启动之前还进行温度的判断，如果温度较高接近预定温度时，减少电加热模块的加热启动后的预定时间，且温度越接近预定时间越减少，由此减少不必要的加热，进一步降低能耗，直至温度超过预定温度时，不进行加热。同样的，作为另一种方式，电加热模块的加热启动之前还进行时间的判断，通过两次电加热模块的加热启动的间隔时间来减少不必要的加热，进一步降低能耗，或者对电加热模块进行保护，避免超温受损或带来危险。As a further option, the temperature or time is determined before the heating of the electric heating module is started: when the water body temperature or the electric heating module temperature is close to the predetermined temperature, the predetermined time after the heating start of the electric heating module is reduced, when the water body temperature or the electric heating When the module temperature exceeds the predetermined temperature, the heating start of the electric heating module is stopped; or the interval between the heating start time of the electric heating module and the last start (or the last heating stop) is lower than the predetermined interval time, and the heating start of the electric heating module is reduced. The scheduled time or the heating start of the electric heating module is stopped. In this solution, the temperature of the electric heating module is further determined before the heating is started. If the temperature is higher than the predetermined temperature, the predetermined time after the heating and starting of the electric heating module is reduced, and the temperature is decreased as the predetermined time is decreased, thereby reducing Unnecessary heating further reduces energy consumption until the temperature exceeds the predetermined temperature without heating. Similarly, as another way, the heating of the electric heating module is performed before the start of the heating, and the interval between the heating starts of the electric heating module is used to reduce unnecessary heating, further reducing energy consumption, or heating the electric heating. The module is protected against over-temperature damage or danger.

作为进一步选择，还包括与控制开关并联控制电加热模块启动或停止的第二控制开关，第二控制开关为开启后按照预定时间关闭的延时开关，或者为开启后水体温度或者电加热模块温度按照预定温度关闭的温控开关。该方案中，控制开关和第二控制开关并联设置，两个开关只要其中一个处于开启状态，电加热模块都会启动加热，只有两个开关同时关闭时电加热模块才会停止加热。并联的设置，可以在不影响现有常规即热式电热水龙头的原有操作模式下，实现本申请的“加热前置”。Further, the method further includes controlling, by the control switch, a second control switch for starting or stopping the electric heating module in parallel, the second control switch is a time delay switch that is turned off according to a predetermined time after being turned on, or is a water body temperature or an electric heating module temperature after the opening. A temperature-controlled switch that is turned off at a predetermined temperature. In this solution, the control switch and the second control switch are arranged in parallel, and as long as one of the two switches is in an open state, the electric heating module starts heating, and the electric heating module stops heating only when the two switches are simultaneously turned off. The parallel arrangement can realize the "heating front" of the present application without affecting the original operation mode of the conventional conventional instant electric hot water faucet.

作为进一步选择，控制开关的开启和关闭和第二控制开关的开启和关闭各自独立。该方案中，控制开关和第二控制开关的各自独立，使得对热水的使用非常灵活：使用加热前置时，可在加热前置进行中的任一时刻，按现有电热水龙头常规使用方式(出水与加热同时进行)通过开启控制开关开启电热水龙头，此种情形下，加热前置效果仅部分实现(水龙头出水初始温度介于冷水与热水之间)，电加热模块将不间断地持续工作加热，水龙头出水温度随时间逐渐升高至热水温度。从另一个角度来讲，加热前置技术是将储存在电热水龙头内，分布于加热体周围的水提前一段加热加热，将这部分水加热至适合使用的温度，然后在稍后使用中开启水龙头手柄即可从出水口放出热水。实际使用中，加热前置可在启动控制开关正常使用热水前通过启动第二控制开关而启动，可适当提前一段时间启动，例如：早晚涮牙时，可先启动第二控制开关启动加热前置，在前置加热进行时同时进行牙具、牙膏等必备操作，然后开启水龙头手柄启动控制开关，水龙头出水口即可第一时间出热水，热水不等待。当然，具有加热前置功能的电热水龙头，也可以进行普通电热水龙头的操作，例如：不使用加热前置功能(不操作第二控制开关)，直接开启水龙头手柄(只操作控制开关)，此时与现有电热水龙头具有相同的使用方式、功能及效果。As a further option, the opening and closing of the control switch and the opening and closing of the second control switch are independent. In this solution, the control switch and the second control switch are independent of each other, so that the use of hot water is very flexible: when using the heating front, it can be used at any time during the heating front, according to the conventional electric hot water tap. (At the same time as the water and heating), the electric hot water tap is turned on by turning on the control switch. In this case, the heating front effect is only partially realized (the initial temperature of the tap water is between cold water and hot water), and the electric heating module will continue uninterruptedly. When the work is heated, the tap water temperature gradually rises to the hot water temperature with time. From another point of view, the heating front-end technology is to store the electric water in the electric faucet, and the water distributed around the heating body is heated in advance, and the water is heated to a temperature suitable for use, and then the faucet is turned on in later use. The handle can release hot water from the water outlet. In actual use, the heating front can be started by starting the second control switch before the start control switch normally uses the hot water, and can be started in advance for a certain period of time, for example, when the tooth is pressed in the morning and evening, the second control switch can be started before the heating is started. Set, when the front heating is carried out, carry out the necessary operations such as dental tools and toothpaste, and then turn on the faucet handle to start the control switch. The faucet outlet can be used for hot water for the first time, and the hot water does not wait. Of course, the electric faucet with the heating front function can also operate the ordinary electric faucet, for example: without using the heating front function (do not operate the second control switch), directly open the faucet handle (only operate the control switch), at this time It has the same usage, function and effect as existing electric faucets.

作为另一进一步选择，控制开关和第二控制开关联动一并开启，但控制开关和第二控制开关的关闭各自独立。该方案中，可以直接通过一个操作启动控制开关或第二控制开关，简化操作。例如，在现有常规即热式电热水龙头上增加第二控制开关时，可以直接利用常规即热式电热水龙头上已有的控制开关对第二控制开关的“加热前置”进行启动。反过来也是如此。As another further option, the control switch and the second control switch are turned on together, but the control switch and the second control switch are independently turned off. In this solution, the control switch or the second control switch can be directly activated by one operation to simplify the operation. For example, when the second control switch is added to the conventional conventional instant electric hot water faucet, the "heating front" of the second control switch can be directly activated by using the existing control switch on the conventional instant electric faucet. The reverse is also true.

作为进一步选择，控制开关和第二控制开关均由控制水龙头出水开启或关闭的外部操作机构一并控制其开启，外部操作机构控制水龙头出水开启时控制开关和第二控制开关均开启，外部操作机构控制水龙头出水关闭时控制开关关闭。该方案中，可以通过外部操作机构(例如水龙头手柄、旋扭等)开启水龙头出水后又迅速关闭的方式，实现“加热前置”的启动：外部操作机构控制水龙头出水开启时控制开关和第二控制开关均开启，电加热模块启动加热，随即外部操作机构控制水龙头出水关闭而控制开关关闭，但此时第二控制开关继续开启，电加热模块继续加热，直至达到第二控制开关预定时间或预定温度而关闭。As a further option, the control switch and the second control switch are both controlled by an external operating mechanism that controls the water outlet opening or closing of the faucet, and the external operating mechanism controls the faucet water to open when the control switch and the second control switch are both turned on, the external operating mechanism The control switch is turned off when the faucet water is turned off. In this solution, the external heating mechanism (such as faucet handle, knob, etc.) can be used to open the faucet and then quickly close, so that the "heating front" can be activated: the external operating mechanism controls the faucet water to open the control switch and the second The control switch is turned on, the electric heating module starts heating, and then the external operating mechanism controls the faucet water to close and the control switch is closed, but at this time the second control switch continues to be turned on, and the electric heating module continues to heat until the second control switch reaches the predetermined time or predetermined The temperature is turned off.

作为另一进一步选择，控制开关和第二控制开关的开启和关闭与外部操作机构控制水龙头出水的开启或关闭各自独立。As a further alternative, the opening and closing of the control switch and the second control switch are independent of the opening or closing of the external operating mechanism to control the faucet water discharge.

The difference is that the control switch that controls the start or stop of the electric heating module is the start-stop sensor and its corresponding start-stop signal processing controller. The sensors are command sensors and human body sensing sensors.

当指令传感器接收到使用者发出的指令，并且人体感应传感器感应到使用者位于感应区域，其对应启停信号处理控制器给出导通模式，电加热模块启动，稍后通过操控机构开启水龙头出水，即可在水龙头出水的第一时间获得热水。关闭热水时，可以先发出指令其对应启停信号处理控制器给出断开模式关闭电加热模块，然后操作操控机构关闭水龙头出水，也可同时关闭。When the command sensor receives the command from the user, and the human body sensing sensor senses that the user is located in the sensing area, the corresponding start and stop signal processing controller gives a conduction mode, the electric heating module is activated, and then the faucet is opened by the operating mechanism.

After the start-stop signal processing controller is given the conduction mode, the electric heating module is started, and the faucet is not opened for a long time, and the safety protector is The temperature safety protector will stop the electric heating module from continuing to heat up.

本实施例中，电热水龙头为双进水管(分别连接自来水及热水器)、单阀芯(冷热混水阀芯)、一个操控机构(手柄)。In this embodiment, the electric hot water tap is a double inlet water pipe (connected to tap water and water heater respectively), a single valve core (cold and hot mixed water valve core), and a control mechanism (handle).

实施例3：参考图5、6所示，本实施例与实施例2相似，不同的是，启停传感器增加了温度传感器，该温度传感器设于水龙头内用以感应水体温度的水体温度传感器。Embodiment 3: Referring to FIGS. 5 and 6, the present embodiment is similar to Embodiment 2 except that the start-stop sensor adds a temperature sensor, and the temperature sensor is disposed in the faucet to sense a water body temperature.

方式二：一种节水省电省时的电热水龙头，其设有使水龙头出水升温的电加热模块，以及控制该电加热模块启动或停止的控制开关，还包括与控制开关并联控制电加热模块启动或停止的第二控制开关，第二控制开关为开启后按照预定时间关闭的延时开关，或者为开启后水体温度或者电加热模块温度照预定温度关闭的温控开关。Method 2: A water-saving, electricity-saving and time-saving electric hot water faucet, which is provided with an electric heating module for heating the faucet water, and a control switch for controlling the start or stop of the electric heating module, and a parallel control electric heating module with the control switch The second control switch that is started or stopped, the second control switch is a time delay switch that is turned off according to a predetermined time after being turned on, or a temperature control switch that is turned off after the water body temperature is turned on or the temperature of the electric heating module is turned off according to a predetermined temperature.

实施例4：参考图7所示，本实施例与实施例1相似，不同的是，还包括与控制开关并联控制电加热模块启动或停止的第二控制开关，第二控制开关为开启后按照预定时间关闭的延时开关，或者为开启后按照预定温度(水体或者加热体)关闭的温控开关。Embodiment 4: Referring to FIG. 7, the embodiment is similar to Embodiment 1, except that the second control switch for controlling the start or stop of the electric heating module is controlled in parallel with the control switch, and the second control switch is opened according to the second control switch. A time-delay switch that is turned off at a predetermined time, or a temperature-controlled switch that is turned off according to a predetermined temperature (water body or heating body) after turning on.

本实施例中，控制开关为启停开关控制元件，为水流开关，此处水流开关为设于水龙头内由水流所对应水压驱动的微动开关；第二控制开关为第二启停开关控制元件，为触摸延时开关，此处触摸延时开关为触摸时开关导通并延时至预定时间断开。In this embodiment, the control switch is a start/stop switch control component, which is a water flow switch, where the water flow switch is a micro switch that is driven by a water pressure corresponding to the water flow in the faucet; the second control switch is a second start/stop switch control. The component is a touch delay switch, where the touch delay switch is turned on when the touch is turned on and is delayed until the predetermined time is turned off.

使用热水时，首先触摸延时开关使延时开关导通，电加热模块启动并延时至触摸延时开关关闭。稍后，短时间使用热水，通过操控机构开启电热水龙头出冷水，水龙头即可在出水的第一时间流出热水并在短时间内连续热水流出，直到通过操控机构关闭水龙头出水；长时间使用热水，通过操控机构开启电热水龙头出热水，此时，水龙头内由水流所对应水压驱动的微动开关导通，电加热模块启动，水龙头即可在出水的第一时间流出热水并长时间持续提供热水，直到通过操控机构关闭水龙头出水，同时微动开关断开电加热模块停止加热。When using hot water, first touch the delay switch to make the delay switch turn on, the electric heating module starts and delay until the touch delay switch is turned off. Later, the hot water is used for a short time, and the electric hot water tap is turned on by the operating mechanism to discharge the cold water. The faucet can discharge the hot water at the first time of the water discharge and continuously discharge the hot water in a short time until the water is turned off by the control mechanism; Using hot water, the electric hot water tap is turned on by the control mechanism. At this time, the micro switch driven by the water pressure corresponding to the water flow is turned on, the electric heating module is activated, and the tap can discharge the hot water at the first time of the water discharge. The hot water is continuously supplied for a long time until the water is turned off by the operating mechanism, and the micro switch is turned off to stop the heating.

作为优选，水龙头内由水流所对应水压驱动的微动开关，在水流满足一定的流量(例如流量大于每秒1升)或者所对应水压满足一定的压力(例如压力大于0.03MPa)导通，使用热水更加安全，避免因水龙头出现小流量漏水故障启动电加热模块，避免使用热水时因开启流量过小电加热模块容易出现过热等不安全状况发生。Preferably, the micro switch in the faucet driven by the water pressure corresponding to the water flow is turned on when the water flow meets a certain flow rate (for example, the flow rate is greater than 1 liter per second) or the corresponding water pressure satisfies a certain pressure (for example, the pressure is greater than 0.03 MPa). It is safer to use hot water to avoid starting the electric heating module due to the small flow leakage of the faucet. When the hot water is used, the unsafe condition such as overheating of the electric heating module is prone to overheating.

参考图8所示，本实施例中，还可以优选进一步设置安全保护器，安全保护器中的温度安全保护器仅在水龙头内水体温度超标或者加热装置温度超标时停止电加热模块继续加热，确保使用安全。Referring to FIG. 8 , in this embodiment, it is also preferable to further provide a safety protector. The temperature safety protector in the safety protector stops heating only when the water body temperature in the faucet exceeds the standard or the temperature of the heating device exceeds the standard, and ensures that the electric heating module continues to heat. Safe to use.

此外，电加热模块的加热启动之前还可以优选进一步进行温度或时间的判断：当水体温度或者电加热模块温度接近预定温度时，减少电加热模块的加热启动后的预定时间，当水体温度或者电加热模块温度超过预定温度时，停止电加热模块的加热启动；或者电加热模块的加热启动距离上次启动(或者最后一次加热停止)的间隔时间低于预定间隔时间，减少电加热模块的加热启动后的预定时间或停止电加热模块的加热启动。温度或时间的判断可以通过在第二控制开关中设置对应的温度或时间启停开关控制元件或启停传感器及其对应启停信号处理控制器等方式实现。例如：本实施例中，在第二控制开关(启停开关控制元件)中加入双金属片温度开关(设于电加热模块加热体上),在使用者触摸延时开关后，若电加热模块温度超过预定温度时，双金属片温度开关断开停止电加热模块的加热启动。同样，若第二控制开关采用启停传感器及其对应启停信号处理控制器，可以增加设置水体温度传感器，根据水体温度调整电加热模块的加热启动后的预定时间，也可以在启停信号处理控制器中增加时间采集，根据距离上次启动或者距离上次加热停止(包括控制开关控制的加热和第二控制开关控制的加热)的间隔时间，调整电加热模块的加热启动后的预定时间或停止电加热模块的加热启动。In addition, the temperature or time may be further determined before the heating of the electric heating module is started: when the water body temperature or the temperature of the electric heating module approaches a predetermined temperature, the predetermined time after the heating start of the electric heating module is reduced, when the water body temperature or electricity When the temperature of the heating module exceeds the predetermined temperature, the heating start of the electric heating module is stopped; or the interval between the heating start time of the electric heating module and the last start (or the last heating stop) is lower than the predetermined interval time, and the heating start of the electric heating module is reduced. After the predetermined time or stop the heating start of the electric heating module. The temperature or time can be determined by setting a corresponding temperature or time start/stop switch control element or start-stop sensor and its corresponding start-stop signal processing controller in the second control switch. For example, in this embodiment, a bimetal temperature switch (provided on the heating element of the electric heating module) is added to the second control switch (starting and stopping switch control element), and the electric heating module is used after the user touches the delay switch. When the temperature exceeds the predetermined temperature, the bimetal temperature switch is turned off to stop the heating start of the electric heating module. Similarly, if the second control switch adopts the start-stop sensor and its corresponding start-stop signal processing controller, the water body temperature sensor may be added to adjust the predetermined time after the heating start of the electric heating module according to the water body temperature, and the start-stop signal processing may also be performed. Increasing the time acquisition in the controller, adjusting the predetermined time after the heating start of the electric heating module or according to the interval between the last start or the last heating stop (including the heating controlled by the control switch and the heating controlled by the second control switch) Stop the heating start of the electric heating module.

实施例5：参考图9、10所示，本实施例与实施例4相似，不同的是，控制开关为设于水龙头内用以感应水流通过并给出水流信号的水流传感器及其对应启停信号处理控制器，此处水流感应器为霍尔水流传感器。Embodiment 5: Referring to FIG. 9 and FIG. 10, this embodiment is similar to Embodiment 4, except that the control switch is a water flow sensor disposed in the faucet for sensing water flow and giving a water flow signal and corresponding start and stop. Signal processing controller, where the water flow sensor is a Hall water flow sensor.

本实施例中，通过操控机构开启电热水龙头出热水，设于水龙头内用以感应水流通过(或者对应的水压)并给出水流信号的霍尔水流传感器给出信号，所对应启停信号处理控制器给出导通模式，电加热模块启动。本实施例中的霍尔水流传感器也可用干簧管水流传感器等类似传感器替代。In this embodiment, the hot water is turned on by the operating mechanism, and the Hall water flow sensor provided in the faucet for sensing the water flow (or corresponding water pressure) and giving the water flow signal gives a signal, and the corresponding start and stop signal is given. The processing controller gives a conduction mode and the electric heating module starts. The Hall water flow sensor in this embodiment can also be replaced with a reed switch water flow sensor or the like.

在本实施例中，采用水流传感器及其对应启停信号处理控制器替代实施例4中启停开关控制元件，二者等效。In this embodiment, the water flow sensor and its corresponding start-stop signal processing controller are used instead of the start-stop switch control element in Embodiment 4, and the two are equivalent.

实施例6：参考图11、12所示，本实施例与实施例4相似，不同的是，第二控制开关为设于水龙头外壳或外壳以外用以感应使用者指令的第二指令传感器和设于水龙头内用以感应水体水位并给出水位信号的第二水位传感器及其对应第二启停信号处理控制器，此处第二指令传感器为触摸传感器，第二水位传感器为电容式水位传感器。Embodiment 6: Referring to FIGS. 11 and 12, this embodiment is similar to Embodiment 4 except that the second control switch is a second command sensor and device provided outside the faucet casing or casing for sensing user commands. The second water level sensor for sensing the water level of the water body and giving the water level signal in the faucet and the corresponding second start and stop signal processing controller, wherein the second command sensor is a touch sensor, and the second water level sensor is a capacitive water level sensor.

本实施例中，当使用者通过触摸第二指令传感器给出指令，并且第二水位传感器给出水龙头内水体水位处于正常位置信号，其对应第二启停信号处理控制器给出导通模式，电加热模块启动。第二水位传感器可以确保水龙头处于正常供水状态，避免电加热模块在水龙头或者供水***出现漏水、停水等异常状态时启动。In this embodiment, when the user gives an instruction by touching the second command sensor, and the second water level sensor gives a water level water level in the faucet that is in a normal position signal, the second start/stop signal processing controller gives a conduction mode.
