New description: [New technical field] The water tray prevents the hot water from flowing back. It mainly depends on the bottom surface of the floating diaphragm opposite to the inlet of the bottom plate of the water tray, and the plug is arranged to protrude relative to the insert. After the hot water outlet end is closed, the back water is returned to the upper part of the water tray by the back pressure, so that the diaphragm is moved downward, and the water inlet port is plugged, so that the hot water flowing back does not mix with the influent water to reach the water flow. The stability of entry and exit can ensure the safety purpose of the water heater inlet and outlet pipes. ^ [Prior Art] The design of the inlet and outlet water inside the water heater of the traditional water heater is usually set as shown in the fifth to seventh figures, mainly in the center of the disc body (2 〇) under the pressure difference water tray combination, with the water inlet pipe (21 The cold water is introduced from the outside, so that the built-in floating diaphragm (2 2) is controlled as a synchronous control of the gas in the case of influent or hot water, and is left in the bottom of the lower body (2 〇). Through hole (2 3 ), one side is connected with a hole slot for assembling a safety valve (2 4 ), which can be safely and automatically touched when ultrasonic to ensure the safety of the water heater: the whole water inlet operation _ water directly _Perforation (2 3 ) is drained into the lower half of the water tray to control the upward displacement of the floating diaphragm (2 2 ), so as to control the flow control of the gas, and the inlet pipe (2 i ) enters the inside of the disk and then drains (4) Water pipes (2 5 ), which enable the operation of the water to be heated into water, and these water and pressure relief are set under the same pipe with different pipe diameters, because the diameter of the connecting pipe mouth is different, plus the actual single hole Inlet and outlet design, when used, when the water outlet side is closed, the entire heated The hot water will be quickly returned from the return hole (2 6) to the upper and lower sides of the differential pressure water pan. The entire return pressure will be directly squeezed back into the circulating pipe, which will not only cause turbulence, but also due to its return flow. The water pressure on the water inlet side forms a great impact 4 M287423 hit, which often produces vibration and noise when the water is shut off, which creates a safety concern in practical use, which has not been effectively and properly improved; After being heated to have a high-temperature water flow, after returning to the inside of the water tray, not only the change of the actual water supply temperature is formed; further, the hot water reflux is directly mixed with the water inlet of the lower half of the disk body, and the actual progress is formed. The temperature rise state of the water temperature may also cause a change in the gelation of the cold water connection fittings, directly forming a great safety concern in the actual use of the water heater and the inconvenience and trouble of the actual cold water intake. How to increase the current water tray into and out of the water structure The new design will make it easier to avoid the inconvenience of the actual hot and cold water supply and maintain the cold water supply fittings more safely. Practical needs The structure of the current water heater inlet and outlet water is necessary to further improve the design. [New content] The creator has developed a water tray to prevent hot water in view of the current lack of design of the water heater in the water supply and use of the water heater. The countercurrent structure, by means of the separate water inlet and outlet orifices of the lower disc body, so that the water tray forms a pressure-relieving space for the water outlet, which can improve the high-pressure spoiler generated by increasing the water pressure at the moment of reflow. The inlet block is provided with a protruding plug. When the water is closed, the water can be directly plugged into the water inlet. It is actually prevented from mixing with the influent water during hot water recirculation, which affects the water temperature control of the influent. Improve the many safety concerns raised by the current backwater countercurrent. The main purpose of this creation is to set the water inlet and outlet of the water tray to make the inner and the water inlets have a wish space, and the floating diaphragm is arranged with the plug at the position of the water inlet to automatically close the water when returning. The water inlet ensures that the inlet and outlet water are stable, and there is no mixing of hot and cold water to affect the inlet water temperature. 5 M287423 Make sure that the water heater is safer, more stable and practical. [Embodiment] In order to facilitate the review committee to further understand the structural features of the creation and its practical purpose, cooperate with the embodiment diagram and detailed description as follows: The water tray prevents the hot water countercurrent structure, please cooperate with the first to fourth As shown in the figure, the overall structural design for preventing hot water backflow is improved. The bottom surface of the lower disc body (丄〇) is mainly combined under the central floating diaphragm (11) of the differential pressure water pan, and separate inlet and outlet ports are provided (1 2 ). (1 3), respectively, connecting the inlet pipe (14) and the outlet pipe (15), and at the bottom of the diaphragm (11) relative to the central water inlet (12), a plug for conveniently securing the opening is provided (16) ) The appropriate height is raised, and the control of the entire inlet and outlet water is mainly injected directly into the lower half of the inner part of the water tray by the inlet pipe (14), and then flows out from the other side of the water outlet (13) through the outlet pipe (15). The water flow is drained to the heating zone; and the most important creative feature of the creation is that the plug (16) for holding the closure protrudes according to the central position of the diaphragm (11) relative to the water inlet (12), and the block body The convex shape depends on the shape of the lip of the inlet (12). Set to the opposite conical convex shape, when the water supply end is stopped, the returning water flow will be directly returned to the upper side of the diaphragm (11) by the return hole (17), so that the diaphragm (i) is pressed down, thereby making The plug (16) protruding from the lower edge of the diaphragm (1 1) can be inserted into the water inlet (1 2 ) to form a closed portion of the water inlet (1 2 ), and at this time, the backflow can be completely prevented. The hot water is mixed into the inlet pipe (14) and mixed with the influent water, so as to ensure the stability of the inlet water temperature, and the plastic material such as the protection inlet pipe (14) can be received to avoid deterioration or hardening after being heated. Use a safe situation to ensure that the water heater is used for safe maintenance purposes. The 6 M287423 δ and δ 10' separated by the inlet and outlet (12) (13) of this creation are separated from the hot water countercurrent section, which can be easily closed by the water inlet (1 2 ). Prevent mixing and ensure the stability of the water supply temperature and the female full. With this design, the water outlet side can be effectively prevented. When the water is closed immediately, the returning water is returned to the water through the outlet pipe (15). After the upper part of the water tray is inside, due to the enlargement of the internal space of the disc, the water pressure can form a gentle pressure effect at the time of reflow, and the lowering of the diaphragm (1 1 ) synchronously stops or reduces the operation of the gas supply to ensure the use of the water heater. When the timepiece is assembled, it will not be subjected to the supercharge of the instantaneous reflow to generate high vibration, which will destroy the safety and stability of the assembly and achieve the second purpose of safe use of the water heater. In the original position of the central diaphragm (11) opposite to the water inlet (1 2 ) in the water tray, the protruding plug (丄6) is preset, when the returning water pressure diaphragm (1 1) is moved down, The water inlet (i 2 ) can be closed at the same time, so that the inlet and outlet water can be formed in an appropriate buffer, so that when the water is closed, the return water will not mix with the influent water, thereby forming a stable control of the actual influent water temperature, ensuring The safety control of the water heater combustion is designed to improve the safety structure of the hot water counterflow. It is indeed the first of its kind and has practical and safe functions. The overall structure is extremely simple, no need for super processing technology, and the overall production cost is increased. It can achieve the practical control precision effect. It is not comparable to the current design of various pressure difference water tray control design. It is simple, innovative and practical to improve the facts. It is stable for the whole water supply pressure and safe to use. The first to create a design and practical effects. In summary, the water tray of the present invention prevents the hot water from flowing back, directly at the bottom of the central diaphragm of the water tray relative to the water inlet, and when the plug is protruded from the water outlet end of the water heater, when the hot water is returned, Synchronously close the water inlet when the diaphragm moves down to prevent the hot water from flowing back into the water inlet. 'Ensure the stability of the inlet water temperature control and the safety of the connected pipe fittings. The M287423 further enhances the safety and stability of the water heater. The structural improvement and practical characteristics are the first and more practical and effective design designers of similar products. They have indeed met the requirements for new patent improvement applications, and have applied for it according to law.
