Description

一种电热水龙头Electric hot water tap

技术领域Technical field

本发明涉及一种水龙头，尤其涉及一种即热式的电热水龙头。The invention 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：热水器可以提供大流量热水，但从水龙头放出热水前必须要放出一段冷水，而电热水龙头可以即时放出热水，却受功率限制无法提供大流量的热水，虽然热水器与电热水龙头在上述特点上互为优势与劣势，但现有电热水龙头只有一根连接冷水的进水管，无法将热水器与电热水龙头联接使用，实现优势与劣势互补。在另一种电热水龙头的设计方案中，采用了混水阀芯，分别具有冷水进口和热水进口，可以将热水器与电热水龙头联接使用，但电加热装置只设置在热水进口或其上游，即仅对热水进口热水器前面一段冷水进行加热，这种电热水龙头虽然实现了前述优势与劣势互补，但当使用者仅需少量热水，可开启电热水龙头加热功能并放出热水，同时热水器将进入加热状态或者其热水进入热水管道未得到利用，造成热水器无效开机和热能浪费。此外，上述两种电热水龙头都是利用其中的加热装置为日常生活、生产中提供热水(温度可致65℃)，由于电热水龙头中加热装置受先天结构上的限制，存在加热装置容易结垢整机寿命短，水温不宜精确控制导致烫伤事故，热水流量小无法满足使用。Compared with ordinary faucets, there are some electric faucets: water heaters can provide large-flow hot water, but a cold water must be released before the hot water is discharged from the faucet, and the electric faucet can immediately release hot water, but it is unable to provide high-flow heat due to power limitation. Water, although the water heater and the electric faucet are mutually advantageous and disadvantageous in the above characteristics, the existing electric faucet has only one inlet pipe connected with cold water, and the water heater and the electric faucet cannot be connected and used to achieve advantages and disadvantages. In another design scheme of electric faucet, a mixing valve core is adopted, which has a cold water inlet and a hot water inlet respectively, and the water heater can be connected with the electric faucet, but the electric heating device is only disposed at the hot water inlet or upstream thereof. That is, only the cold water in front of the hot water inlet water heater is heated. Although the electric hot water tap achieves the aforementioned advantages and disadvantages, when the user only needs a small amount of hot water, the electric hot water tap heating function can be turned on and the hot water is discharged, and the water heater will When entering the heating state or the hot water entering the hot water pipe is not utilized, the water heater is ineffectively turned on and the heat energy is wasted. In addition, the above two electric hot water taps use the heating device to provide hot water for daily life and production (the temperature can be 65 ° C). Since the heating device in the electric hot water tap is limited by the congenital structure, the heating device is easy to scale. The life of the whole machine is short, and the water temperature should not be accurately controlled to cause burns. The hot water flow is small and cannot be used.

现有技术存在前述问题的根本原因是在于他们的出发点或思维都局限在利用电热水龙头中的加热装置来提供热水，并未考虑利用电热水龙头中的加热装置来提供温水。例如：将电热水龙头中加热装置提供温水，并外接其他热水器提供热水，其加热装置的限温可以控制在20℃至40℃，这种新型电热水龙头(外接有热水器)加热装置不易结构整机寿命长，热水温度可以精确控制避免烫伤事故，热水流量大可满足实际需求。不仅如此，这种新型电热水龙头(外接有热水器)在秋冬春季其加热装置提供的温水可以显著提升使用者的用水体验，而现有水龙头(外接有热水器)和电热水龙头，到了秋天或者春天，特别是冬天，直接放冷水体感就不舒服了，甚至冰冷刺骨无法忍受。The root cause of the prior art problems in the prior art is that their starting point or thinking is limited to the use of heating means in the electric faucet to provide hot water, and the use of heating means in the electric faucet to provide warm water is not considered. For example, the heating device in the electric faucet is provided with warm water, and the other water heaters are externally provided to provide hot water. The temperature limit of the heating device can be controlled at 20 ° C to 40 ° C. The new electric faucet (with external water heater) heating device is not easy to structure. Long life, hot water temperature can be precisely controlled to avoid burns, hot water flow can meet the actual demand. Not only that, but the warm water provided by the heating device in the new electric faucet (with external water heater) in autumn and winter can significantly improve the user's water experience, while the existing faucet (with external water heater) and electric faucet is in autumn or spring, especially It is winter, it is uncomfortable to put cold water directly into the body, and even cold and biting can't stand it.

作为另一进一步选择，设于水龙头内由水流控制的水流开关控制元件，当感受到有水流并且水流量处于特定范围时(比如水流量＞0.7升/分，或者水流量＜3升/分,或者水流量＞0.7升/分且水流量＜3升/分等)水流开关控制元件处于导通模式，感受到无水流或者水流量处于特定范围之外时(比如水流量＜0.7升/分，或者水流量＞3升/分等)水流开关控制元件处于断开模式；同样，当水流传感器感应到水流通过并且水流量处于特定范围时(比如水流量＞0.7升/分，或者水流量＜3升/分,或者水流量＞0.7升/分且水流量＜3升/分等)，其对应启停信号处理控制器给出导通模式，水流传感器感应到没有水流通过或者水流量处于特定范围之外时(比如水流量＜0.7升/分，或者水流量＞3升/分等)，其对应启停信号处理控制器给出断开模式。另外，水流开关控制元件通常可采用水流开关或水压开关等与水流状态相关联的开关控制元件，当感受到有水流或水压时水流开关控制元件处于导通模式，当感受到无水流或水压时水流开关控制元件处于断开模式。比如，当水流开关控制元件采用与水流状态相关联的水压开关时，当感受到有水压并且水压值处于特定范围时(比如水压＞0.04MPa)水流开关控制元件处于导通模式，感受到无水压或者水压值处于特定范围之外时(比如水压＜0.04MPa)水流开关控制元件处于断开模式。同样，当水压传感器感应到水压并且水压处于特定范围时(比如水压＞0.04MPa，或者水压＜0.5MPa)，其对应启停信号处理控制器给出导通模式，水压传感器感应到没有水压或者水压处于特定范围之外时(比如水压＜0.04MPa，或者水压＞0.5MPa)，其对应启停信号处理控制器给出断开模式。As a further alternative, the water flow switch control element, which is controlled by the water flow in the faucet, when there is a flow of water and the water flow is within a certain range (for example, a water flow rate > 0.7 L/min, or a water flow rate < 3 L/min, Or the water flow rate >0.7 liters/min and the water flow rate <3 liters/min, etc.) The water flow switch control element is in the conduction mode, and when the water flow or the water flow is outside the specific range (for example, the water flow rate is <0.7 liter/min, Or water flow > 3 liters / min, etc.) The water flow switch control element is in the open mode; likewise, when the water flow sensor senses the flow of water and the water flow is within a certain range (eg water flow > 0.7 l / min, or water flow < 3 l/min, or water flow >0.7 l/min and water flow <3 l/min, etc., which corresponds to the start-stop signal processing controller to give a conduction mode, the water flow sensor senses that no water flows or the water flow is in a specific range When it is outside (such as water flow <0.7 l / min, or water flow > 3 l / min, etc.), its corresponding start and stop signal processing controller gives the disconnect mode. In addition, the water flow switch control element can generally adopt a switch control element associated with the water flow state, such as a water flow switch or a water pressure switch. When the water flow or the water pressure is sensed, the water flow switch control element is in the conduction mode, when no water flow is felt or The water flow switch control element is in the off mode when the water pressure is applied. For example, when the water flow switch control element uses a water pressure switch associated with the water flow state, when the water pressure is felt and the water pressure value is within a certain range (eg, water pressure > 0.04 MPa), the water flow switch control element is in the conduction mode, When the water pressure or water pressure value is outside the specified range (such as water pressure <0.04MPa), the water flow switch control element is in the disconnect mode. Similarly, when the water pressure sensor senses the water pressure and the water pressure is within a certain range (for example, water pressure > 0.04 MPa, or water pressure < 0.5 MPa), the corresponding start and stop signal processing controller gives a conduction mode, the water pressure sensor When there is no water pressure or the water pressure is outside the specified range (such as water pressure <0.04MPa, or water pressure >0.5MPa), the corresponding start-stop signal processing controller gives the disconnection mode.

In this solution, the control temperature range is preferably set according to the temperature of the water body measured by the temperature switch control element or the temperature sensor disposed in the water flow channel. When the temperature switch control element or the temperature sensor is disposed on the electric heating device, correction is required. Because the temperature of the electric heating device is usually higher than the temperature of the water body, and the degree of the difference is different depending on the internal structural design of the different faucets. Therefore, when the temperature switch control element or the temperature sensor is disposed on the electric heating device, the preset high temperature disconnection temperature is higher, and the temperature range may exceed 65 °C. For example, when the temperature switch control element or the temperature sensor is disposed in the water flow channel and the preset high temperature disconnection temperature is 45° C., when the temperature switch control element or the temperature sensor is disposed on the electric heating device, the preset high temperature is broken. The opening temperature needs to be set higher, for example 75 °C.

The 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 electric heating device is characterized in that: the start-stop control module and the electric heating device are also arranged. The electric heating device is electrically connected to the start-stop control module at the water outlet of the mixing valve core or the cold water outlet of the hot and cold double valve core and the water outlet between the hot water outlet and the water outlet of the faucet, and the electric heating device is controlled accordingly Heating.

其中启停控制模块为启停开关控制元件，启停开关控制元件为设于水龙头内由水流控制的水流开关控制元件。水流开关控制元件通常可采用水流开关或水压开关等与水流状态相关联的开关控制元件，当水龙头内有水流或水压时水流开关控制元件处于导通模式，当水龙头内无水流或水压时水流开关控制元件处于断开模式。The start-stop control module is a start-stop switch control component, and the start-stop switch control component is a water flow switch control component that is controlled by water flow in the faucet. The water flow switch control component can usually adopt a switch control component associated with the water flow state, such as a water flow switch or a water pressure switch. When there is water flow or water pressure in the faucet, the water flow switch control element is in the conduction mode, when there is no water flow or water pressure in the faucet. The water flow switch control element is in the off mode.

当水流开关控制元件处于导通模式，电加热装置启动加热，当水流开关控制元件处于断开模式，电加热装置停止加热。该方案中，通过水流开关控制元件实现一开水龙头就自动加热，一关水龙头就自动停止加热，简单方便。When the water flow switch control element is in the conduction mode, the electric heating device initiates heating, and when the water flow switch control element is in the off mode, the electric heating device stops heating. In this solution, the water tap switch control element realizes that the water tap is automatically heated, and the water tap automatically stops heating when it is closed, which is simple and convenient.

本实施例中，还可以优选以下方案，设于水龙头内由水流控制的水流开关控制元件，当有水流并且水流量处于特定范围时(比如水流量＞0.7升/分，或者水流量＜3升/分,或者水流量＞0.7升/分且水流量＜3升/分等)水流开关控制元件处于导通模式，无水流或者水流量处于特定范围之外时(比如水流量＜0.7升/分，或者水流量＞3升/分等)水流开关控制元件处于断开模式。该优选方案中，将水流量限定在一特定范围内，可以避免因小水流量产生高温水或者因大水流量出现低水温等不良状况。另外，该优选方案中，也可以采用将水压限制在特定范围内，比如，当水流开关控制元件采用与水流状态相关联的水压开关时，当有水压并且水压值处于特定范围时(比如水压＞0.04MPa，或者水压＜0.5MPa) 水流开关控制元件处于导通模式，无水压或者水压值处于特定范围之外时(比如水压＜0.04MPa，或者水压＞0.5MPa)水流开关控制元件处于断开模式In this embodiment, the following scheme may also be preferred, in which the water flow switch control element controlled by the water flow in the faucet has a water flow and the water flow is in a specific range (for example, the water flow rate is >0.7 L/min, or the water flow rate is <3 L). /min, or water flow >0.7 liters / min and water flow <3 liters / min, etc.) The water flow switch control element is in conduction mode, when no water flow or water flow is outside the specified range (such as water flow <0.7 l / min , or water flow > 3 liters / min, etc.) The water flow switch control element is in the disconnect mode. In this preferred embodiment, the water flow rate is limited to a specific range, and it is possible to avoid the occurrence of high temperature water due to small water flow rate or low water temperature due to large water flow rate. In addition, in the preferred embodiment, the water pressure can also be limited to a specific range, for example, when the water flow switch control element adopts a water pressure switch associated with the water flow state, when there is water pressure and the water pressure value is within a specific range. (For example, water pressure > 0.04MPa, or water pressure <0.5MPa) The water flow switch control element is in the conduction mode, when the water pressure or water pressure value is outside the specified range (such as water pressure <0.04MPa, or water pressure>0.5 MPa) water flow switch control element is in disconnect mode

当按一下手动开关控制元件处于导通模式，电加热装置启动加热，再按一下手动开关控制元件处于断开模式，电加热装置停止加热。该方案中，通过手动开关控制元件实现手动加热，和手动关闭停止加热，按需自由控制，最为灵活。When the manual switch control element is in the conduction mode, the electric heating device starts heating, and then the manual switch control element is in the off mode, and the electric heating device stops heating. In this scheme, manual heating is realized by manual switch control elements, and manual heating is stopped to stop heating, which is freely controlled on demand and is most flexible.

本实施例中，还可以优选以下方案，设于水龙头外壳或外壳以外的使用者手动开关控制元件，可以是自锁式触动开关，可以是手动启动的延时开关或者手动复位的温控开关等。当采用手动启动的延时开关时，可以利用手动控制电加热装置的启动加热，利用延时开关的延时功能控制电加热装置的停止加热；当采用手动复位的温控开关时，利用手动控制温控开关启动电加热装置加热，利用温控开关的温度控制功能控制电加热装置的停止加热。In this embodiment, the following scheme may also be preferred.

本实施例中，由于从冷水阀芯冷水出口流出的水流不需要经过电加热装置加热，所以从冷水阀芯冷水出口流出的水流不经过电加热装置从水龙头的出水口流出。例如：电加热装置采用不锈钢加热管，从热水阀芯热水出口流出的水流从不锈钢加热管外表面经过再从水龙头的出水口流出，从冷水阀芯冷水出口流出的水流不经过不锈钢电热管外表面(从位于水龙头内连通冷水阀芯冷水出口与水龙头出水口的连接管管内流过)从水龙头的出水口流出。In this embodiment, since the water flow from the cold water outlet of the cold water valve core does not need to be heated by the electric heating device, the water flow from the cold water outlet of the cold water valve core does not flow out from the water outlet of the faucet through the electric heating device. For example, the electric heating device adopts a stainless steel heating pipe, and the water flowing out from the hot water outlet of the hot water valve core passes through the outer surface of the stainless steel heating pipe and then flows out from the water outlet of the faucet, and the water flowing out from the cold water outlet of the cold water valve core does not pass through the stainless steel electric heating pipe.
