Description

可调射流淋浴设备 技术领域  Adjustable jet shower device
本发明涉及一种射流混液器， 尤其涉及一种应用于太阳能热水器供水系 统中的射流混液器， 属于太阳能热水器技术领域。 背景技术  The invention relates to a jet mixer, in particular to a jet mixer used in a water supply system of a solar water heater, and belongs to the technical field of solar water heaters. Background technique
现有太阳能热水器主要包括承压式和非承压式。  Existing solar water heaters mainly include pressure-bearing and non-pressure-bearing types.
承压式太阳能热水器的工作原理是： 自来水经控制开关进入水箱和热 管， 集热管吸收太阳辐射后通过介质将热能传递给热管中的冷水， 循环加热 水箱中的水， 由于水箱是整体封闭结构， 使用时必需打开冷水进水口， 用自 来水的水压顶出水箱中的热水， 使热水从出水口流入到用水单元。 此种结构 的水箱承受自来水的压力， 出水流量相对较大，使用舒适度较好， 但是， 该 种结构的水箱需要承受 7MPa 的水压， 内部还需增加热管结构， 对密封性要 求较高， 材料较厚， 从而导致热水器的成本较高。  The working principle of the pressure-bearing solar water heater is: the tap water enters the water tank and the heat pipe through the control switch, and the heat collecting pipe absorbs the solar radiation, transfers the heat energy to the cold water in the heat pipe through the medium, and circulates and heats the water in the water tank, because the water tank is an overall closed structure, When using, it is necessary to open the cold water inlet, and use the water pressure of the tap water to push out the hot water in the water tank, so that the hot water flows from the water outlet to the water unit. The water tank of this structure is subjected to the pressure of tap water, the discharge flow rate is relatively large, and the use comfort is good. However, the water tank of the structure needs to withstand the water pressure of 7 MPa, and the heat pipe structure needs to be added inside, and the sealing requirement is high. The material is thicker, resulting in higher cost of the water heater.
非承压式太阳能热水器的工作原理是： 自来水经控制开关连接到水箱的 进出水口（挡水板）， 直至充满水箱和玻璃热管， 玻璃热管吸收太阳光后加热 水箱与玻璃热管中的水， 水箱中的水被加热后再通过进出水口流到室内用水 单元供用户使用。 此种结构的水箱与玻璃热管只承受水箱高度的水压， 受压 较小， 因此， 玻璃热管与水箱不需要耐压设计， 节约材料， 相对于承压式太 阳能热水器来说成本较低。 但是， 该种结构的太阳能热水器， 由于水箱的安 装高度受限于建筑结构，一般很难提供较高水压给出水单元，造成出水单元 的出水流量较小，影响使用舒适度。 中国专利文献 CN1 0301 6421 A公开了一种射流器及具有该射流器的热水 器阀门， 属于非承压式热水器阀门， 其通过设置合理的射流增压结构， 同时 达到了射流增压与降低成本的作用。 然而， 该文献公开的热水器阀门， 其喷 嘴的口径是固定不变的， 在通过冷、 热水流量调节开关分别调整冷、 热水的 进水流量时， 当冷水调节开关的开口小于喷口的口径时， 喷嘴内的工作液的 水压将被降低， 从而使得冷水工作液的喷射速度降低， 其抽吸热水的效果不 好， 从而导致夏天使用时舒适度不高。 The working principle of the non-pressure-bearing solar water heater is: The tap water is connected to the inlet and outlet of the water tank (water retaining plate) through the control switch until it is filled with the water tank and the glass heat pipe, and the glass heat pipe absorbs the sunlight and heats the water in the water tank and the glass heat pipe, the water tank The water in the water is heated and then flows through the water inlet and outlet to the indoor water unit for the user to use. The water tank and the glass heat pipe of this structure only bear the water pressure at the height of the water tank, and the pressure is small. Therefore, the glass heat pipe and the water tank do not need a pressure-resistant design, and the material is saved, and the cost is lower than that of the pressure-bearing solar water heater. However, in this type of solar water heater, since the installation height of the water tank is limited by the building structure, it is generally difficult to provide a water pressure unit with a higher water pressure, resulting in a smaller outlet flow rate of the water outlet unit, which affects the comfort of use. Chinese patent document CN1 0301 6421 A discloses a jet and a water heater valve having the same, which belongs to a non-pressure-bearing water heater valve, which achieves a jet pressurization and a cost reduction by setting a reasonable jet pressurization structure. effect. However, in the water heater valve disclosed in the document, the diameter of the nozzle is fixed, and when the flow rate of the cold water and the hot water is respectively adjusted by the cold and hot water flow regulating switch, when the opening of the cold water regulating switch is smaller than the diameter of the nozzle At this time, the water pressure of the working fluid in the nozzle is lowered, so that the injection speed of the cold water working fluid is lowered, and the effect of sucking the hot water is not good, resulting in low comfort in summer use.
中国专利文献 CN1 02086941 B公开了一种混水阀门， 包括阀体， 所述阀 体上设置有阀体冷水进口、 阀体热水进口、 阀体出水口以及与阀体冷水进口 相连的喷嘴， 所述喷嘴上设有喷嘴冷水进口和喷嘴冷水出口， 所述阀体内还 设有与所述阀体热水进口相连的热水调节腔以及与所述阀体出水口相连的 混水腔， 所述混水腔与所述热水调节腔通过位于热水调节腔一端的阀体热水 出口相连， 并且混水腔还与所述喷嘴通过喷嘴冷水出口相连。 当需要调整热 水流量时，可以向阀体内旋进或者选出喷嘴，减小或增大热水进口的截面积， 与此同时， 喷嘴也减小或增大冷水进口的界面剂， 从而调整冷热水的混合比 例。 但是， 其在使用过程中存在以下缺陷：  Chinese Patent Publication No. CN1 02086941 B discloses a water mixing valve including a valve body, which is provided with a valve body cold water inlet, a valve body hot water inlet, a valve body water outlet, and a nozzle connected to the valve body cold water inlet. The nozzle is provided with a nozzle cold water inlet and a nozzle cold water outlet, and the valve body is further provided with a hot water regulating chamber connected to the valve body hot water inlet and a water mixing chamber connected to the valve body water outlet. The mixing water chamber and the hot water regulating chamber are connected through a valve body hot water outlet located at one end of the hot water regulating chamber, and the mixing chamber is also connected to the nozzle through the nozzle cold water outlet. When it is necessary to adjust the hot water flow, the nozzle can be screwed in or selected from the valve body to reduce or increase the cross-sectional area of the hot water inlet. At the same time, the nozzle also reduces or increases the interface agent of the cold water inlet, thereby adjusting The mixing ratio of hot and cold water. However, it has the following defects in its use:
在旋转喷嘴时， 针阀与喷嘴一同运动， 在此过程中， 喷嘴和针阀不发生 相对运动， 从而使得冷水出口的截面积一直保持不变， 这样， 当冷水进口的 截面积小于冷水出口的截面积时， 喷嘴内冷水的水压将很小， 难以实现较好 的喷射效果， 而为了保证较好的喷射效果， 就需要同时调整针阀， 从而将冷 水出口的截面积减小， 进而要求对针阀和喷嘴进行同时调节， 增大了使用难 度， 而若不同时调整针阀和喷嘴则将难以保证较好的出水效果以及较高的使 用舒适度。  When the nozzle is rotated, the needle valve moves together with the nozzle. During this process, the nozzle and the needle valve do not move relatively, so that the cross-sectional area of the cold water outlet remains unchanged, so that the cross-sectional area of the cold water inlet is smaller than that of the cold water outlet. When the cross-sectional area is small, the water pressure of the cold water in the nozzle will be small, and it is difficult to achieve a better injection effect. In order to ensure a better injection effect, it is necessary to simultaneously adjust the needle valve, thereby reducing the cross-sectional area of the cold water outlet, and further requiring Simultaneous adjustment of the needle valve and the nozzle increases the difficulty of use, and if the needle valve and the nozzle are not adjusted at the same time, it is difficult to ensure a good water discharge effect and high use comfort.
从以上论述可知，如何对混水阀门进行改进以使其同时达到较高的使用 舒适度、较低的使用成本以及较为便利的搡作是现有技术中还没有解决的技 术难题。 发明内容 From the above discussion, it can be known that how to improve the mixing valve to achieve higher use comfort, lower use cost and convenient work is not solved in the prior art. Skills. Summary of the invention
