The present invention breakthroughs the concept that the structural performances and usages of the instantaneous type and water storage type water heater with a history of nearly one hundred year have to be separated from each other, and it also overcomes the drawbacks in the prior art, so that present invention changes the criterion that the instantaneous water heating type electric water heater can only be used in the large scale power supply system.

Description

环保型即热储水式电热水器 技术领域  Environmental protection type instantaneous water storage electric water heater
本发明涉及电热技术, 特别是一种环保型即热储水式电热水器。 背景技术  The invention relates to electric heating technology, in particular to an environmentally-friendly instant water storage electric water heater. Background technique
电热水器发明至今已有差不多一个世纪, 到现在其基本概念及设计都没 有大分别, 只不过是材料及安全上的改良, 从实用性角度上, 还没有突破。 电 热水器主要分为两大类, 即热式及储水式。 即热式热水器, 意思在使用时开电 即有热水供应。 储水式则先打开电源加温一段时间才可使用热水。 上述两大类型热水器之功能区别及优劣比较如下表:  Electric water heaters have been invented for almost a century, and so far their basic concepts and designs have not changed much. They are just improvements in materials and safety. From a practical point of view, there has been no breakthrough. There are two main types of electric water heaters, namely thermal and water storage. Instant water heaters mean that there is hot water supply when the power is turned on when in use. In the water-storage type, the power is turned on for a period of time before hot water can be used. The functional differences and advantages and disadvantages of the above two types of water heaters are as follows:
从上表可发觉两者都各有其优点, 但从家庭角度来说, 储水式电热水器较 为受欢迎, 图 1 是其结构原理示意图, 原因是安装即热式热水器之客观条件难 以配合,例如需要把供电系统由单相更改为三相及耗电量庞大,功率最小为 18kW 380v, 而价格高及运作费贵, 不是一般家庭可负担。  From the above table, you can find that both have their own advantages, but from the perspective of the family, storage electric water heaters are more popular. Figure 1 is a schematic diagram of the structure and principle, because the objective conditions of installing instant water heaters are difficult to match. For example, the power supply system needs to be changed from single-phase to three-phase, and the power consumption is huge. The minimum power is 18kW 380v, and the price is high and the operation cost is expensive, which is not affordable for ordinary families.
由于上述因素, 家庭使用者在没有其它产品可代替及选择下, 只有选购储 水式热水器。 但储水式热水器最大缺点之一, 就是在使用前要预早把热水器加 热约 30~50分钟, 方可使用, 但使用时间不长, 举例; 一电热水器容量 25公升, 功率 3kW, 进水温度 20 , 热水设定温度 65 , 即升温 45 , 如以下公式计算: t = (G *ΔΤ * Cp) I (864 * 80/100 * 3) Due to the above factors, household users have no choice but to purchase water storage water heaters. But one of the biggest shortcomings of storage water heaters is that they need to be added before use. It can be used for about 30 ~ 50 minutes, but the use time is not long, for example; an electric water heater with a capacity of 25 liters, a power of 3kW, a water inlet temperature of 20, a hot water setting temperature of 65, that is, a temperature rise of 45, as calculated by the following formula: t = (G * ΔΤ * Cp) I (864 * 80/100 * 3)
t = (25 * 45 * 1 ) I (864 * 0. 8 * 3)  t = (25 * 45 * 1) I (864 * 0. 8 * 3)
t = 1125 I 2074 = 0. 5424 时 = 33分  t = 1125 I 2074 = 0.55424 hours = 33 minutes
使用计算: Use calculations:
把热水出水口接上固定恒温阀,把恒温阀出水温度调至 40 ,水流速度 300 升 /时, 只可使用 5- 6分钟左右。  Connect the hot water outlet to a fixed thermostatic valve, adjust the water temperature of the thermostatic valve to 40, and the water flow rate is 300 liters / hour, and it can only be used for about 5-6 minutes.
从上述计算所得, 给用户觉得储水式热水器在给电加热后, 而在可使用热 水比较下, 觉得不化算。 己现时平均电费 0. 9元 /千瓦小时, 上述例子用 33分, 即费用为 1. 50元。 上述例子有两大缺点, 预热需时太久及热水输出时间太短。 发明内容  From the above calculations, the user feels that the water storage water heater is not cost-effective when it is heated and compared with the available hot water. The current average electricity cost is 0.9 yuan per kilowatt-hour. The above example uses 33 minutes, which means the cost is 1.50 yuan. The above example has two major disadvantages: it takes too long to warm up and the time for hot water output is too short. Summary of the Invention

如图 5所示, 本发明的工作原理及过程如下:  As shown in FIG. 5, the working principle and process of the present invention are as follows:
本发明之二合一 即热储水式电热水器 , 包含 '直射快速增热式' 及 '直射 循环储水式'两种模式加热方式。 这样的设计可尽量利用加热器 3 启动后产生 辐射热的同时, 让低温进水流经收集器立即把辐射热吸收 热传递定义: 从高温 热水传到低温水、 经热水管排出储水箱外、 可立即使用。 而低温进水与热出水 之温差増减可由发热器输入功率及储水箱之水温而定, 或调节用水之流量来调 校适合温度。 实验证明其工作原理: 首先采用'直射循环储水式', 测试数据; 进 水温度为 20 、 输入功率为 3000瓦、 储水箱容量 25公升、 待预热至储水箱热 水平均温度 65 、 调校热出水使用温度到 40 、 流量 300升 /时、 可提供 30分 钟不断的热水淋浴。 这时, 储水箱内已加热的热水温度已下降至接近进水温度, 不存在着温度差、 令热传递起不了作用, 不能补给热水至注射喷咀 7, 把热水 温度提高。 此时, 热水器即自动进入'直射快速增热式'状态, 冷进水直接被发热 器加温及实时排出使用, 这时热水器变为即热式, 而使用者祇需适量调节出水 水温及流量, 便可无限量提供长时间热水淋浴。 The two-in-one hot water storage type electric water heater of the present invention includes two modes of heating: a direct direct heating type and a direct direct circulation storage type. This design can make full use of the radiant heat generated by the heater 3 at the same time, and let the low-temperature incoming water flow through the collector to immediately transfer the radiant heat absorption heat transfer Definition: From high-temperature hot water to low-temperature water, and discharged out of the storage tank through the hot water pipe Can be used immediately. The temperature difference between the low temperature inlet water and the hot outlet water can be determined by the input power of the heater and the water temperature of the water storage tank, or by adjusting the flow rate of water to adjust the suitable temperature. The experiment proves its working principle: Firstly, it adopts the direct-flow circulating water storage type, and the test data; the water inlet temperature is 20, the input power is 3000 watts, the storage tank capacity is 25 liters, and it is to be warmed up to the average temperature of the hot water in the storage tank. The temperature of the hot water output is 40, the flow rate is 300 liters / hour, and a continuous hot shower can be provided for 30 minutes. At this time, the temperature of the heated hot water in the water storage tank has dropped to close to the temperature of the inlet water. There is no temperature difference, which makes the heat transfer impossible. It cannot supply hot water to the injection nozzle 7, The temperature increases. At this time, the water heater automatically enters the 'direct-fire rapid heating type' state, and the cold incoming water is directly heated by the heater and discharged in real time. At this time, the water heater becomes instantaneous, and the user only needs to adjust the temperature and flow of the water. , You can provide unlimited hot shower for a long time.
本发明的环保型即热储水式电热水器目的及其工作原理是这样达到的: "直注快速增热式" 的工作原理是: 当热水器接驳至冷供水及热出水口, 热出水口接驳淋浴花洒, 待热水器注满冷水后, 启动加热器 3, 开启花洒热水 阀, 此时热水会不停地从花洒头源源喷出, 祇需调校适合水温便可享受舒适的 淋浴乐趣。 工作原理是这样的, 首先冷水从万向接头 2注入, 经冷迸水导管 9, 进入辐射热收集器 4 内里之辐射热导管 5, 把电加热器 3之辐射热吸收再向辐 射热收集器 4底部喷射, 此时, 吸收后之初次冷水温度会被提升, 此乃第一次 加温预热。 然后预热温水再流经加热器 3之发热体作全面性吸收于加热器 3发 放出之辐射热, 温水吸收了辐射热后, 温度急促提升, 释出气泡及体积膨胀, 热水在辐射热收集器 4之顶部会集, 当聚集至一定压力时, 便从注热导管 6释 放到直接热注射喷咀 7经万向接头 2喷出热水使用。 此时, 直接热注射喷咀 7 内部之细腰管文氏管原理与 8 界面处因有热水高速流经而产生低压, 即负压, 而顶部热水便从双向导管 8之入水口 11被吸进喷咀 7, 再与收集器 4之热水混 合, 混合后之热水温度会被再度提升, 即第三次加热然后再经万向头排放到使 用点或花洒喷头等。  The purpose of the environmentally-friendly instant water storage electric water heater and its working principle are achieved as follows: The working principle of the "direct injection rapid heating type" is: When the water heater is connected to the cold water supply and the hot water outlet, the hot water outlet Connect the shower head. After the water heater is filled with cold water, turn on the heater 3 and open the shower hot water valve. At this time, hot water will be continuously sprayed from the shower head source. Just adjust the water temperature to enjoy Comfortable shower fun. The working principle is as follows. First, cold water is injected from the universal joint 2 and passes through the cold water pipe 9 and enters the radiant heat pipe 5 inside the radiant heat collector 4. The radiant heat of the electric heater 3 is absorbed and returned to the radiant heat collector. 4Bottom spray, at this time, the first cold water temperature will be increased after absorption, this is the first heating and preheating. The preheated warm water then flows through the heating element of the heater 3 to fully absorb the radiant heat emitted by the heater 3. After the warm water absorbs the radiant heat, the temperature rises rapidly, releasing bubbles and volume expansion, and the hot water is radiated by heat The top of the collector 4 gathers, and when it reaches a certain pressure, it is released from the heat injection pipe 6 to the direct thermal injection nozzle 7 to spray hot water through the universal joint 2 for use. At this time, the low-waist tube Venturi principle inside the direct thermal injection nozzle 7 and the interface 8 generate low pressure due to hot water flowing at high speed, that is, negative pressure, and the top hot water flows from the water inlet 11 of the two-way conduit 8 It is sucked into the nozzle 7 and mixed with the hot water of the collector 4, and the temperature of the hot water after mixing will be raised again, that is, it is heated for the third time and then discharged to the use point or shower nozzle through the gimbal.
"直注循环储水式" 的工作原理是: 当热水器接驳至冷供水及热出水口, 热出水口接驳使用点或淋浴花洒, 待热水器注满冷水后, 启动加热器 3, 此时 冷水在辐射热收集器 4内里吸收由加热器 3发放之辐射热, 令冷水快速加温及 将水中分子分解, 释出气泡及体积膨胀, 热水在辐射热收集器 4之顶部会集, 当聚集至一定压力时, 便从注热导管 6释放到直接热注射喷咀 7, 此时因热水 出口还是在关闭状态, 所以热水便从喷咀 7形成三通经双向导管 8向上经入水 口 11释放至热水器顶部,这时热水从双向导管 8释放之同时,是带有正压力的, 这样, 在双向导管 8之入水口 11便会产生一强烈喷流, 喷向顶部周围, 令顶部 热水移动, 渐向下层推进, 与此同时, 在辐射热收集器 4里之热水不停经注热 导管 6、 热注射喷咀 7及双向导管 8的入水口 11排放至顶部, 而辐射热收集器 4之底部双向补充水道 10因物理现象, 不停将热水器下层之冷水注入辐射热收 集器 4, 补充被排放之热水, 形成一强烈对流及循环现象。 由双向补充水道 10 吸进→经加热器 3燃烧加温一再经双向导管 8的入水口 11排放, 很快整个热水 器便被加热完毕, 随时备用。 The working principle of the "direct injection circulating water storage type" is: When the water heater is connected to the cold water supply and hot water outlet, the hot water outlet is connected to the point of use or the shower. After the water heater is filled with cold water, the heater 3 is started. When cold water absorbs the radiant heat emitted by the heater 3 in the radiant heat collector 4, the cold water is rapidly heated and the molecules in the water are decomposed to release air bubbles and volume expansion. The hot water gathers on top of the radiant heat collector 4, When it reaches a certain pressure, it is released from the heat injection pipe 6 to the direct thermal injection nozzle 7. At this time, because the hot water outlet is still closed, hot water forms a three-way from the nozzle 7 through the bidirectional pipe 8 and passes upward. The water inlet 11 is released to the top of the water heater. At this time, the hot water is released from the two-way pipe 8 with positive pressure. In this way, a strong jet is generated at the water inlet 11 of the two-way pipe 8 and is sprayed around the top. The hot water at the top is moved and gradually advanced to the lower layer. At the same time, the hot water in the radiant heat collector 4 is continuously discharged to the top through the water inlet 11 of the heat injection pipe 6, the thermal injection nozzle 7 and the two-way pipe 8. Radiation heat harvest Bottom 4 of a bidirectional supplemented by physical phenomena waterway 10, the lower heater will be kept cold water into the radiant heat received The collector 4 supplements the discharged hot water, forming a strong convection and circulation phenomenon. It is sucked in by the two-way supplementary water channel 10 → combusted and heated by the heater 3, and then discharged through the water inlet 11 of the two-way pipe 8. Soon, the entire water heater is heated up and ready for use at any time.
