[0048] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.
[0049] like Figure 1 As shown, a gas water heater comprises a water volume regulating device 1 as described above, and the water volume regulating device 1 is arranged in the water inlet pipe of the water heater.
[0050] like Figures 2 to 4 As shown, this embodiment provides a water quantity regulating device 1, which is arranged in the water inlet pipeline of the gas water heater, and includes a water flow passage, a flow regulating component 120, a water flow outlet 1202 and a driving component 121. The water flow passage includes a water inlet end 103 and a water outlet end 104; the flow regulating component 120 is arranged in the water flow passage, and the flow regulating component 120 includes a regulating block 1201. When the water flows through the water flow passage, it flows through the water flow outlet 1202. The gap between the regulating block 1201 and the water flow outlet 1202 forms a regulating channel. The regulating block 1201 can approach or move away from the water flow outlet 1202 to change the area of the regulating channel. The driving component 121 includes an expansion airbag 1211, which is arranged on the side of the regulating block 1201 facing away from the water flow outlet 1202 and can drive the regulating block 1201 to approach or move away from the water flow outlet 1202 by expansion or contraction.
[0051] In this embodiment, the flow regulating component 120 can be driven by the driving component 121 to adjust the cross-sectional area of the regulating channel, thereby adjusting the water flow entering the water heater. When the water inlet temperature is too low or the water flow is too large, the water flow entering the water heater can be reduced by reducing the flow area, so that the heat required to heat to the set temperature is lower, thereby ensuring the water outlet temperature. At the same time, reducing the flow area can also play a role in stabilizing the pressure when the water flow is too large. The driving component 121 drives the movement of the flow regulating component 120 by expanding and squeezing the expansion airbag 1211.
[0052] like Figure 3 As shown, the expansion airbag 1211 has an elastic surface 1213 and a fixed surface. The elastic surface 1213 is a surface of the expansion airbag 1211 that contacts the adjustment block 1201 . The expansion airbag 1211 is expanded by stretching the elastic surface 1213 .
[0053] In this embodiment, the expansion airbag 1211 is composed of a fixed surface that cannot expand and an elastic surface 1213 that can expand. The elastic surface 1213 faces the adjustment block 1201, and the remaining part is a non-deformable fixed surface, so that the expansion airbag 1211 can only expand toward one side, and the expansion efficiency is higher and more controllable.
[0054] In other embodiments, the fixing surface may not be provided so that the inflatable airbag 1211 is inflated as a whole.
[0055] like Figure 2 , 3 As shown, the driving component 121 also includes a heating component, and the expansion airbag 1211 is filled with an inert gas. The heating component is arranged in the expansion airbag 1211 and expands the inert gas by heating, thereby expanding the expansion airbag 1211. The use of inert gas can prevent the gas from being too active, reacting with other substances, or undergoing other unnecessary changes after heating.
[0056] In this embodiment, the driving component 121 expands the airbag through the heating unit 1212. No motor is required, no direct contact with the water flow is required, and no malfunction is caused by impurities in the water flow. It can be used in an environment with poor water quality.
[0057] like Figure 2 As shown, the water flow path includes a first path 11 and a second path 12, and the flow regulating component 120 is arranged in the second path 12. When the water flows through the second path, it flows through the water flow port 1202, and the water outlets of the first path 11 and the second path 12 converge at the water outlet end 104.
[0058] In this embodiment, when the flow regulating assembly 120 is not working, the second passage 12 remains unobstructed, and the amount of water flowing out of the outlet is large. When the flow regulating assembly 120 is working, the second passage 12 is closed, and the amount of water entering the water heater is reduced.
[0059] like Figure 2 As shown, the water flow regulating device 1 includes a housing 101, a first passage 11 is arranged in the housing 101, the housing 101 extends outwardly perpendicular to the water flow direction to form an extension cavity 102, and the second passage 12 is arranged in the extension cavity 102. In this embodiment, the second passage 12 is arranged in the extension cavity 102 extending outward from the housing 101, so that its structure does not affect the first passage 11, ensuring the normal flow of water in the first passage 11. In other embodiments, the housing 101 can also be arranged at other positions.
[0060] like Figure 2 As shown, the water outlet 104 is provided with a flow stabilizing valve 13. In this embodiment, the flow stabilizing valve 13 can stabilize the water pressure, making the water outlet more stable. The flow stabilizing valve 13 can adopt the common flow stabilizing valve 13 structure in the prior art, which will not be described in detail here.
[0061] like Figure 3 As shown, the regulating block gradually converges from the end away from the water flow port 1202 to the end close to the water flow port 1202 to form a wedge-shaped structure. The circumference of the water flow port 1202 has a wedge-shaped edge corresponding to the regulating block 1201, and the regulating block 1201 can fit the wedge-shaped edge and close the water flow port 1202. In this embodiment, the wedge-shaped structure allows the sealing surface to be longer and the sealing effect is better. In other embodiments, it can also be set to other shapes, such as only one opening.
[0062] like Figure 2 As shown, the water outlet 104 is arranged perpendicular to the water flow direction of the water inlet 103. In this embodiment, the water flows out of the cavity after turning in the cavity, further absorbing the impact force and pressure of the water flow.
[0063] like Figure 3 As shown, the expansion airbag 1211 is connected to the adjustment block 1201 through an elastic connector. In this embodiment, the flow stabilization effect is smoother.
[0064] Figure 2The structure and working principle diagram of the water quantity regulating device 1. The water quantity regulating device 1 is composed of a housing 101, a flow regulating valve 13, a flow sensor and a flow regulating component 120. The flow regulating component 120 includes an expansion airbag, a heating resistor coil, a flow regulating block 1201 and a spring. The flow regulating block 1201 is designed to be level with the two springs. The contact surface between the expansion airbag and the spring is made of elastic material, and the remaining airbag part is non-elastic material. The inside of the airbag is filled with inert gas. When the heating resistor coil heats up, the inert gas expands, and the elastic surface 1213 is deformed to squeeze the contact surface spring. The spring acts on the flow regulating block 1201 to push it to one side.
[0065] The water flow regulating device 1 is installed at the water inlet 103 of the gas water heater. The top and bottom of the shell 101 are respectively designed with a water flow inlet and an outlet, and the flow regulating component 120 is installed in the middle of the shell 101. There is a first straight passage inside the shell 101, and a second passage formed by the side and the flow regulating component 120. When the flow regulating component 120 is not working, the second passage remains unobstructed, and the amount of water flowing out of the outlet is large. When the flow regulating component 120 is working, the second passage is closed, and the amount of water entering the water heater is reduced.
[0066] The two sections of the heating resistor coil in the expansion airbag are connected to the electronic controller, and the corresponding heat is generated according to the different currents output by the electronic controller, thereby controlling the expansion state of the elastic surface 1213. The expansion state of the elastic surface 1213 will affect the flow area between the flow regulating block 1201 and the second channel of the housing 101, and further adjust the flow rate of the water outflow of the water regulating device 1.
[0067] When the outlet water temperature of the gas water heater cannot reach the set temperature, and the electronic controller determines that the working load of the water heater is normal, the flow regulation program starts to run. The electronic controller gradually increases the current of the heating resistor coil, and the coil continues to heat up, causing the elastic surface 1213 to expand and push the flow regulation block 1201 closer to the second channel. When the outlet water of the water heater reaches the set temperature, the electronic controller reduces the output current to keep the elastic surface 1213 in a certain expansion state, thereby stabilizing the target flow and temperature.
