Description
技术领域technical field
本实用新型涉及一种热水器技术领域，尤其涉及一种水管连接器以及安装有该水管连接器的热水器。The utility model relates to the technical field of water heaters, in particular to a water pipe connector and a water heater equipped with the water pipe connector.
背景技术Background technique
现有电热水器的防漏电措施均利用绝缘管对水路进行延长，形成较大的水路电阻，通过该水路电阻限制因电热水器的内胆内的电热管漏电等原因导致内胆水体带电向人体泄漏的电流,达到保护人身安全的目的，这就是通俗所称的防电墙技术。目前行业中大多将绝缘管内置在内胆中，如CN01135300.7专利和CN200610097237.1专利，使绝缘管长度与其内半径r达到一定比值，确保需要的水路阻值。然而，因绝缘管内置在内胆中，长度受到限制，要达到上述比值只能减小管半径，由此将导致进出水流量减小，并构成堵塞隐患。除此之外，市场还有外置在内胆外的防电墙，如200920238448.1等专利，其水路做成盘绕式(类似蚊香盘)，为了减小体积，流道也做成比较细小，同样存在进出水流量小的问题；由于此类防电墙需与内胆的水管接头连接，加上自身的高度，与整机配合后，所占的空间体积也较大，因而行业应用不多。The existing anti-leakage measures for electric water heaters use insulating pipes to extend the waterway to form a large waterway resistance. Through this waterway resistance, the electric water body in the inner tank of the electric water heater is restricted from leaking to the human body due to electric heating tube leakage in the inner tank of the electric water heater. Current, to achieve the purpose of protecting personal safety, this is the popular so-called anti-electric wall technology. At present, in the industry, most of the insulation tubes are built into the liner, such as CN01135300.7 patent and CN200610097237.1 patent, so that the length of the insulation tube and its inner radius r reach a certain ratio to ensure the required waterway resistance. However, because the length of the insulating tube is limited because it is built into the inner tank, the only way to achieve the above ratio is to reduce the radius of the tube, which will result in a decrease in the inflow and outflow of water and cause a potential blockage. In addition, the market also has anti-electricity walls built outside the inner tank, such as patents such as 200920238448.1. There is a problem of small inflow and outflow of water; because this kind of anti-electric wall needs to be connected with the water pipe joint of the inner tank, and its own height, after being matched with the whole machine, the space occupied by it is also relatively large, so there are not many industrial applications.

The cold water flow channel 11, the connector body 10 is made of insulating material, the lower end surface of the connector body 10 is formed with a water inlet joint 13 and a water outlet joint 14, and the water inlet joint 13 and the cold water flow channel 11 The water outlet joint 14 is in communication with the hot water flow channel 12, the water inlet joint 13 is suitable for introducing cold water into the cold water flow channel 11, and the water outlet joint 14 is suitable for introducing the hot water flow channel The hot water in 12 is introduced into the bathing water pipe outside the water heater, and the upper end surface of the connector body 10 is formed with a water inlet hole 15 and a water outlet hole 16, and the water inlet hole 15 communicates with the cold water flow channel 11, The water outlet hole 16 communicates with the hot water flow channel 12, the cold water flow channel 11 is divided into a first cold water flow channel 111 and a second cold water flow channel 112, and the water flow direction in the first cold water flow channel 111 is the same as that of the The direction of water flow in the second cold water flow channel 112 is opposite. The hot water flow channel 12 is divided into a first hot water flow channel 121 and a second hot water flow channel 122. The direction of water flow in the first hot water flow channel 121 is the same as The direction of water flow in the second hot water flow channel 122 is opposite, and the two blocking covers 191 and the connector main body 10 form a groove suitable for connecting the first hot water flow channel 121 and the second hot water flow channel. 122 communicates with or connects the first cold water flow channel 111 with the second cold water flow channel 112 .
冷水从进水接头13流入冷水流道11中，呈往复式设置的第一冷水流道111 以及第二冷水流道112，能够增加冷水流道11的整体长度，以增强水路电阻；此外，冷水流道11采用往复式设置，能够充分利用空间，增大流道横截面积，进一步增强水路电阻，达到防漏电的目的，同时有效避免冷水流道11被堵塞的问题。Cold water flows into the cold water flow channel 11 from the water inlet joint 13, and the first cold water flow channel 111 and the second cold water flow channel 112 that are reciprocatingly arranged can increase the overall length of the cold water flow channel 11 to enhance the water resistance; The flow channel 11 adopts a reciprocating arrangement, which can make full use of the space, increase the cross-sectional area of the flow channel, further enhance the water resistance, achieve the purpose of preventing leakage, and effectively avoid the problem that the cold water flow channel 11 is blocked.
水流方向如图中箭头所示，进入连接器本体中的冷水将沿第一冷水流道111 流经第二冷水流道112并从进水孔15进入到热水器中，热水器将对进入的冷水进行加热，并将加热后的热水从出水孔16导入热水流道12中，热水流道12分成呈往复式设置的第一热水流道121以及第二热水流道122(即往复式流道设置)，以增加热水流道12的整体长度，以增强水路电阻；此外，利用热水流道 12采用往复式设置，能够充分利用空间，增大流道横截面积，进一步增强水路电阻，达到防漏电的目的，同时有效避免热水流道12被堵塞的问题；热水流经热水流道12后从出水接头14排出连接器本体。此外，由于冷水流道11与热水流道12采用往复式流道设置，流道内压力基本相等，不存在大的压力差，因此其间隔可以做得更薄、更节省材料、更小体积。The direction of water flow is shown by the arrow in the figure. The cold water entering the connector body will flow along the first cold water flow channel 111 through the second cold water flow channel 112 and enter the water heater from the water inlet hole 15. The water heater will treat the incoming cold water heating, and the heated hot water is introduced into the hot water flow channel 12 from the water outlet hole 16, and the hot water flow channel 12 is divided into a first hot water flow channel 121 and a second hot water flow channel 122 which are reciprocatingly arranged (that is, a reciprocating type flow channel setting) to increase the overall length of the hot water flow channel 12 to enhance the water resistance; in addition, the hot water flow channel 12 adopts a reciprocating setting, which can make full use of the space, increase the cross-sectional area of the flow channel, and further enhance the The resistance of the water circuit achieves the purpose of preventing electric leakage, and at the same time effectively avoids the problem that the hot water flow channel 12 is blocked; after the hot water flows through the hot water flow channel 12, it is discharged from the connector body from the water outlet joint 14 . In addition, since the cold water flow channel 11 and the hot water flow channel 12 are reciprocating flow channels, the pressures in the flow channels are basically equal and there is no large pressure difference, so the intervals can be made thinner, saving materials and reducing volume.
此外通过设置堵盖191将第一热水流道121与第二热水流道122连通以及第一冷水流道111与第二冷水流道112连通，使得第一热水流道121与第二热水流道122以及第一冷水流道111与第二冷水流道112形成往复式流道设置，同时方便检修时使用者将堵盖191打开以将连接器本体内污水排出。In addition, the first hot water flow channel 121 is communicated with the second hot water flow channel 122 and the first cold water flow channel 111 is communicated with the second cold water flow channel 112 by setting the blocking cover 191, so that the first hot water flow channel 121 is connected with the second hot water flow channel 121. The hot water flow channel 122 and the first cold water flow channel 111 and the second cold water flow channel 112 form a reciprocating flow channel arrangement, and at the same time, it is convenient for the user to open the blocking cover 191 to discharge the sewage in the connector body during maintenance.
冷水流道11以及热水流道12横截面可呈圆形、方形等形状设置，以配合连接器主体10的形状。The cross-sections of the cold water channel 11 and the hot water channel 12 can be arranged in a circular shape, a square shape, etc., to match the shape of the connector body 10 .
如连接器本体水平截面积大于竖直截面面积时，可将第一冷水流道111、第二冷水流道112以及第一热水流道121、第二热水流道122设置为水平横向排列，以充分利用连接器本体的横截面积，达到最佳的防漏电效果；如连接器本体水平截面积小于竖直截面面积时，则可将第一冷水流道111、第二冷水流道112以及第一热水流道121、第二热水流道122设置为上下排列，以充分利用连接器本体的横截面积，达到最佳的防漏电效果。If the horizontal cross-sectional area of the connector body is larger than the vertical cross-sectional area, the first cold water flow channel 111, the second cold water flow channel 112, the first hot water flow channel 121, and the second hot water flow channel 122 can be arranged horizontally and laterally , to make full use of the cross-sectional area of the connector body to achieve the best anti-leakage effect; if the horizontal cross-sectional area of the connector body is smaller than the vertical cross-sectional area, the first cold water flow channel 111 and the second cold water flow channel 112 can be And the first hot water flow channel 121 and the second hot water flow channel 122 are arranged up and down to make full use of the cross-sectional area of the connector body and achieve the best anti-leakage effect.
热水流道12以及冷水流道11的长度与横截面积之比大于或等于45cm/cm2，防漏电效果好。国家标准GB4706.12-2006附录AA.13.2条款要求，电热水器在 1.25KΩ.cm试验用水和额定电压条件下测试，泄漏电流不得超过5mA。根据其具体测试方法(加权接触电流测试方法)以及实际测试经验数据，当水路电阻大于56.2KΩ，即可满足上述要求。由R＝ρ*L/S导出R/ρ＝L/S，即56.2KΩ/1.25K Ω.cm≈45/cm，因此，只要水路长度L和水路截面积S之比大于45倍，即可使水路电阻大于56.2KΩ。以本实施例为例，其流道截面积S设计为0.5cm2，流道长度L＝0.5cm2*45/cm＝22.5cm，因此，把流道长度设计大于22.5cm，即可使泄漏电流小于5mA。The ratio of the length to the cross-sectional area of the hot water flow channel 12 and the cold water flow channel 11 is greater than or equal to 45 cm/cm 2 , and the leakage prevention effect is good. The national standard GB4706.12-2006 appendix AA.13.2 requires that the electric water heater should be tested under the conditions of 1.25KΩ.cm test water and rated voltage, and the leakage current should not exceed 5mA. According to its specific test method (weighted contact current test method) and actual test experience data, when the water circuit resistance is greater than 56.2KΩ, the above requirements can be met. R/ρ=L/S is derived from R=ρ*L/S, that is, 56.2KΩ/1.25KΩ.cm≈45/cm. Therefore, as long as the ratio of the length L of the waterway to the cross-sectional area S of the waterway is greater than 45 times, it can be Make the water resistance greater than 56.2KΩ. Taking this embodiment as an example, the flow channel cross-sectional area S is designed to be 0.5cm2, and the flow channel length L=0.5cm2*45/cm=22.5cm. Therefore, if the flow channel length is designed to be greater than 22.5cm, the leakage current can be less than 5mA.
第一堵盖191以及第二堵盖191可采用自身螺纹或螺钉与连接器主体10密封配合，密封性好。The first blocking cover 191 and the second blocking cover 191 can use their own threads or screws to seal fit with the connector main body 10 , and the sealing performance is good.
