Description
本实用新型是家用热水供给装置The utility model is a domestic hot water supply device
对改善人类生活质量起关键作用的建筑业的进步正在国民经济中发挥着越来越重要的作用，其中，生活用水质量的提高及其使用功能的完善也是各国建筑业研究关注的重点，尤其是家庭住宅中热用水的供应系统，是众多普通家庭在设计改善自己居住条件时优先要考虑解决的问题。针对发展中国家，尤其是中国普通居民家庭居住面积仍较小的特点，目前工业界主要提供二种实用的热水系统来解决这一问题：(1).管道式燃气热水器(2).电热式热水器。管道式燃气热水器的特点是，燃气热值高，加热速度快，体积小，操作简单可靠，在燃气流量和加热量一定时，水温主要靠控制水量来调节，即出水小时水温高，出水大时水温低。管道式燃气热水器的缺点是不易做到对热水进行保温，当家庭需要多用途(如厨房和卫生等)同时使用热水时，难以采用一台燃气热水器同时提供足够的热水供使用，而按装多台燃气热水器也往往受到燃气供应量，通氧量和安装场所等条件的限制。电热式热水器的特点是加热方式简单可靠，可很方便地实现对热水进行保温。但由于受到我国目前居民用电负载量的限制，在有限的电负载功率下，不易做到对水快速加热，故需要设置不同体积的热储水箱来满足用户的需要。家庭多用途热水的供应量受到储水箱体积的限制。The progress of the construction industry, which plays a key role in improving the quality of human life, is playing an increasingly important role in the national economy. Among them, the improvement of the quality of domestic water and the improvement of its use functions are also the focus of research on the construction industry in various countries, especially The supply system of hot water in family houses is a problem that many ordinary families should first consider when designing and improving their living conditions. In view of the characteristics of developing countries, especially the small living area of ordinary households in China, the industry mainly provides two kinds of practical hot water systems to solve this problem: (1). Pipeline gas water heater (2). Electric heating type water heater. Pipeline gas water heaters are characterized by high calorific value of gas, fast heating speed, small size, simple and reliable operation. The water temperature is low. The disadvantage of pipeline gas water heaters is that it is not easy to keep hot water hot. When the family needs to use hot water for multiple purposes (such as kitchen and sanitation) at the same time, it is difficult to use a gas water heater to provide enough hot water for use at the same time. Installing multiple gas water heaters is also often limited by gas supply, oxygen flow and installation sites. The electric water heater is characterized in that the heating method is simple and reliable, and it can easily realize the heat preservation of hot water. However, due to the limitation of the current residential electricity load in our country, it is difficult to quickly heat the water under the limited electrical load power, so it is necessary to set up thermal water storage tanks of different volumes to meet the needs of users. The supply of domestic multi-purpose hot water is limited by the volume of the storage tank.
本实用新型的目的是设计一种既节省能源又能解决家庭多用途热水供应量问题的组合式热水供给装置。The purpose of the utility model is to design a combined hot water supply device which not only saves energy but also can solve the problem of domestic multi-purpose hot water supply.
本实用新型按如下程式设计：The utility model is designed according to the following formula:
常温水输入CWx→燃气加热Gx+电加热Ex→热水输出HWx Normal temperature water input CW x → gas heating G x + electric heating E x → hot water output HW x
在该装置中，普通常温水源CWx通过进水管道输入到一个组合式的二级热水装置。该二级热水装置内部的第一级为管道燃气Gx加热装置，第二级为带储水功能的电Ex加热装置。最终被加热的热水由输出管道输出。In this device, the common normal warm water source CW x is input to a combined secondary hot water device through the water inlet pipe. The first stage inside this two-stage hot water installation is a piped gas G x heating unit, and the second level is an electric E x heating unit with water storage function. The hot water that is finally heated is exported by the output pipe.
本实用新型的组合式热水供给装置，是由燃气加热装置和电加热装置组成，将管道式燃气加热器与冷水进水管直接连接。燃烧气体一般为煤气，也可为液化气体、天然气等其它可燃气体。燃气加热装置的结构和加热原理与现有燃气热水加热器相似，当接通冷水，水流发生流动，燃气被自动点燃，对冷水进行加热。被燃气热水装置加热的热水通过连接管道进入到电加热装置被继续加热至所需的温度，并通过恒温装置对热水进行保温。The combined hot water supply device of the utility model is composed of a gas heating device and an electric heating device, and the pipeline gas heater is directly connected with the cold water inlet pipe. The combustion gas is generally coal gas, but also other combustible gases such as liquefied gas and natural gas. The structure and heating principle of the gas heating device are similar to the existing gas hot water heaters. When the cold water is connected, the water flows, and the gas is automatically ignited to heat the cold water. The hot water heated by the gas water heating device enters the electric heating device through the connecting pipe and is continuously heated to the required temperature, and the hot water is kept warm by the constant temperature device.
较为简单的制作方式可以将现有燃气热水器和电热水器经改装组合成一体，即将燃气热水器的出水口直接与电热水器的进水口相连，便构成了组合式热水供给装置。The relatively simple production method can be that the existing gas water heater and electric water heater are refitted and combined into one, that is, the water outlet of the gas water heater is directly connected with the water inlet of the electric water heater, and a combined hot water supply device is formed.
本实用新型制作时要对水的加热温度进行分级控制，以便达到节能增效的目的，即前级燃气热水装置的出水温度被控制在40-60℃，后级具有储水功能的电加热装置中的水温被控制在60～100℃，从而每一级热水升温幅度不是很大，使得热值被充分利用。When the utility model is made, the heating temperature of the water should be controlled in stages, so as to achieve the purpose of energy saving and efficiency enhancement, that is, the outlet water temperature of the front-stage gas water heating device is controlled at 40-60°C, and the latter stage has electric heating with water storage function The water temperature in the device is controlled at 60-100°C, so that the heating range of each level of hot water is not very large, so that the calorific value is fully utilized.
本实用新型的工作方式为：在一定的燃气流量和水流量下，当热水端的开关开启，水发生流动，输入的常温水经第一级管道式燃气加热器Gx被快速加热到一定的温度，如40-60℃范围，然后流入到第二级电加热器Ex，被继续升温到70-100℃范围。由于采用了二级加热方式，每级被加热的水升温幅度较小，因此，即使后级采用电加热方式，也可实现短时间快速将水加热的目的。后级的电加热装置具有较好的控温和保温功能，能实现对储水箱中的热水进行长时间低功耗高效率保温，即当热水开关关闭，热水停止使用时，燃气系统自动关闭，而通过电加热装置中的恒温系统对具有一定容积储水箱中的热水进行低功耗高效率自动保温，为用户下次使用热水提供了方便。The working mode of the utility model is: under a certain gas flow rate and water flow rate, when the switch of the hot water end is turned on, the water flows, and the input normal temperature water is quickly heated to a certain level by the first-stage pipeline gas heater G x The temperature, such as in the range of 40-60°C, then flows into the second electric heater Ex , which is further raised to the range of 70-100°C. Due to the adoption of the two-stage heating method, the temperature rise of the heated water in each stage is small. Therefore, even if the electric heating method is used in the subsequent stage, the purpose of quickly heating the water in a short time can be achieved. The electric heating device in the latter stage has a good temperature control and heat preservation function, which can realize long-term low power consumption and high-efficiency heat preservation for the hot water in the water storage tank, that is, when the hot water switch is turned off and the hot water is stopped, the gas system will It is automatically closed, and the constant temperature system in the electric heating device performs low power consumption and high efficiency automatic insulation of the hot water in the water storage tank with a certain volume, which provides convenience for users to use hot water next time.
本实用新型仅采用一个燃气和电加热组合式热水供应装置，就可在普通家庭较小居住面积的条件下，实现多用途热水快速供应的目的，并在热水加热过程中，使家庭的生活用燃气和电的负载得到最合理的分配，提高了使用效率，给用户带了方便。并且，当燃气或电供应装置单独发生故障时，各加热装置依然可发挥独立的热水供给功能，而不影响使用。The utility model only adopts a gas-fired and electric heating combined hot water supply device, which can realize the purpose of fast multi-purpose hot water supply under the condition of a small living area of ordinary families, and make the family The domestic gas and electricity loads are allocated most reasonably, which improves the use efficiency and brings convenience to users. Moreover, when the gas or electric supply device breaks down independently, each heating device can still play an independent hot water supply function without affecting the use.

图2是本实用新型实例示意图。Fig. 2 is a schematic diagram of an example of the utility model.
本方法的实施例如下： An example of this method is as follows:
如图1的原理所示，采用前级为管道式燃气加热，后级为储水电加热的二级组合式热水加热装置。当冷水流进该系统中，在一定的燃气流量和水流量下，冷水经第一级管道式燃气加热器被快速加热到一定的温度，如40-60℃范围，然后流入到第二级电加热器，被继续升温到70-100℃范围。在这样一个二级加热系统中，每级被加热的水升温幅度较小，因此，可实现短时间快速加热水的目的。当热水停止使用时，燃气系统自动关闭，电加热装置以较小的功耗对储水箱中的热水进行自动保温，便于用户下次使用。As shown in the principle of Figure 1, a two-stage combined hot water heating device is adopted in which the front stage is pipeline gas heating, and the rear stage is water storage and electric heating. When cold water flows into the system, under a certain gas flow and water flow, the cold water is quickly heated to a certain temperature through the first-stage pipeline gas heater, such as 40-60°C, and then flows into the second-stage electric heater. The heater is continued to heat up to the range of 70-100°C. In such a two-stage heating system, the temperature rise of the water heated in each stage is small, so the purpose of rapidly heating water in a short time can be realized. When the hot water is out of use, the gas system is automatically shut down, and the electric heating device automatically keeps the hot water in the water storage tank with low power consumption, which is convenient for the user to use next time.
图2是一个集成化的装置设计实例剖面图，具有较高的热转换效率。装置被设计成圆柱形，在加热器的最外层绕有燃气加热的螺旋管。当用户用水时，进水开关被打开，低温水从TC口流入，并在螺旋管p内自上往下流动(按水流W箭头方向指示)。与此同时，燃气从燃气管G流入，从底部被自动点燃，将螺旋管内的水快速加热到40-60℃。被第一级燃气加热装置加热的水从螺旋管的底部流出，按序进入到由T1、T2和T3组成的电加热器，其温度分布为：T3(80-100℃)＞T2(70-80℃)＞T1(60-70℃)。被加热的水最终从TH口流出。当停止用水时，燃气加热器自动停止工作。电加热器通过T1-T3对热水箱中的水进行保温，由热传感器S控制，按需将水保温在80-100℃范围，以便随时供用户多用途使用。Figure 2 is a cross-sectional view of an integrated device design example with high heat conversion efficiency. The device is designed in a cylindrical shape, and a gas-heated spiral tube is wound around the outermost layer of the heater. When the user uses water, the water inlet switch is turned on, and the low-temperature water flows in from the TC port, and flows from top to bottom in the spiral pipe p (according to the direction of the water flow W arrow). At the same time, the gas flows in from the gas pipe G and is automatically ignited from the bottom, rapidly heating the water in the spiral pipe to 40-60°C. The water heated by the first-stage gas heating device flows out from the bottom of the spiral tube, and enters the electric heater composed of T1, T2 and T3 in sequence, and its temperature distribution is: T3 (80-100°C) > T2 (70- 80°C) > T1 (60-70°C). The heated water finally flows out from the TH port. When the water is stopped, the gas heater will automatically stop working. The electric heater keeps the water in the hot water tank warm through T1-T3, controlled by the thermal sensor S, and keeps the water in the range of 80-100°C as needed, so that it can be used by users for multiple purposes at any time.
