Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Refer to the attached Figure 1 to attached Figure 3 , a heat storage type drinking water machine system, including a heat storage tank 5, an overflow tank 6 and a two-way valve device A. The overflow tank 6 is installed on the top of the heat storage tank 5. The overflow tank 6 is provided with an exhaust port 63 communicating with the atmosphere, and the two-way valve device A is installed between the heat storage tank 5 and the overflow tank 6. When the heat storage tank 5 is in a heating state, an exhaust passage b1 is formed between the two-way valve device A and the heat storage tank 5 so that the internal and external pressures in the heat storage tank are the same, avoiding pressure bearing. When the user takes hot water from the heat storage tank 5, the exhaust passage b1 is closed, and the user can take water without delay, which is very convenient. The heat storage tank 5 is provided with an expansion water passage 51, an exhaust passage b1 and a hot water outlet passage 53. The expansion water passage 51 is located at the bottom of the heat storage tank 5, and the exhaust passage b1 is provided at the top of the heat storage tank 5; preferably, the heat storage tank 5 has a water inlet passage 50, and the water inlet passage 50 is connected to the water inlet h at the bottom of the heat storage tank 5. A control valve b is installed on the water inlet passage 50 to control whether the raw water is connected to the water inlet h of the heat storage tank. At the same time, one end of the above-mentioned expansion water passage 51 is connected to the heat storage tank 5, and the other end is connected to the overflow tank 6. A valve 51a is also installed on the expansion water passage 51 or the hot water outlet passage 53. Preferably, the valve 51a is a one-way valve device. Further, the water inlet passage 50 and the expansion water passage 51 can be integrally connected into an integral water passage by using a Venturi tube 50b. The Venturi tube 50b has a water inlet c1, a first water outlet c2 and a second water outlet c3. The water inlet c1 is connected to the raw water, the first water outlet c2 is connected to the water inlet h of the heat storage tank, and the second water outlet c3 is connected to the overflow tank 6.

[0025] Refer to attached Figure 2 and attachedFigure 3 When the water in the heat storage tank 5 is heated, the heat storage tank 5 is connected to the atmospheric pressure through the exhaust channel b1, and the water vapor is discharged into the atmosphere through the exhaust channel b1. The heat storage tank 5 does not need to be pressurized. At the same time, the water in the heat storage tank 5 expands due to heating and enters the overflow tank 6 through the expansion water channel 51; when the user takes water through the hot water outlet channel 53, the exhaust channel b1 is closed, and at the same time, the water in the overflow tank 6 is recycled to the heat storage tank 5 through the expansion water channel 51 for continuous recycling. The present invention is provided with an overflow tank and connected to the heat storage tank through the exhaust channel and the expansion water channel, wherein the expansion water channel is connected to the bottom (water inlet) of the heat storage tank, the exhaust channel is connected to the top of the heat storage tank, and the overflow tank is provided with an exhaust port connected to the atmosphere; in this way, due to the existence of the expansion water channel and the design of the consistent internal and external pressures of the heat storage tank, the heat storage tank does not need to be pressurized, the water temperature range can be controlled within the range of 30-95 degrees, and it can effectively solve the defects of unwarranted water discharge from the water outlet during heating and delayed water discharge from the water outlet during water taking.

[0026] In a specific embodiment, referring to the attached Figure 4 and attached Figure 5 The two-way valve device A is installed in a vertical manner when in use. The two-way valve device A includes a valve body 1, an inner body 2 and a sealing ball 3. The valve body 1 has an inlet 11 and an outlet 12. The inlet 11 is connected to the heat storage tank. The inner body 2 is arranged in the valve body 1. The accommodating space 21 is a hollow structure open up and down. The sealing ball 3 is arranged in the accommodating space 21 of the inner body; in addition, an upper sealing ring 41 is placed at the upper end of the outer periphery of the inner body 2, and a lower bracket or a lower sealing ring 42 is placed at the lower end. When the sealing ball 3 is at the lower end of the inner body 1 under the action of its own gravity, there is a gap a between the sealing ball 3 and the lower end of the inner body 1, and the gas can be discharged from the gap a into the accommodating space 21 of the inner body, and finally discharged from the outlet 12 of the valve body. Of course, the two-way valve device may also not include the inner body 2, and the above-mentioned accommodating space 21 may be directly formed in the valve body 1, and the above-mentioned upper sealing ring 41 and the lower bracket (or lower sealing ring) 42 may be placed at the upper and lower ends of the above-mentioned accommodating space 21. In this way, when the sealing ball is at the lower end of the accommodating space 21, the above-mentioned gap a for gas discharge is also formed between the sealing ball 3 and the valve body 1, which can also realize the function of discharging gas from the gap.

[0027] Furthermore, the structure between the heat storage tank 5, the overflow tank 6 and the two-way valve device A can be as shown in the attached figure. Figure 6 and attached Figure 7As shown. The heat storage tank 5 has an opening 51. The overflow tank 6 has a cavity 61 inside. The two-way valve device A extends into the cavity 61 and is arranged. The opening 51 of the heat storage tank extends into the valve body 1 of the two-way valve device. The opening 51 of the heat storage tank and the accommodation space 21 of the valve body communicate to form an exhaust passage b1. A sealing gasket b2 is arranged between the outer periphery of the opening 51 and the valve body 1 to ensure the sealing performance of the connection between the two. Preferably, the upper end of the opening 51 is in direct contact and cooperation with the lower bracket 42 or the lower sealing ring 42'. Further, the outlet 12 of the two-way valve device A is located at the top of the overflow tank 6, or in other words, the opening 51 of the heat storage tank is connected to the top of the overflow tank 6 through the exhaust passage b1. Specifically, there is a protrusion 62 at the top of the overflow tank 6. A protruding cavity 62a higher than the highest water level of the overflow tank 6 is formed inside the protrusion 62. The outlet 12 of the two-way valve device is located in the protruding cavity 62a, that is, the height of the air outlet of the exhaust passage b1 or the outlet 12 is higher than the highest water level of the overflow tank. In this way, when the water vapor in the heat storage tank 5 is discharged into the protruding cavity 62a through the exhaust passage b1, water-vapor separation is carried out in the overflow tank 6, thereby buffering the pressure of the water vapor and separating the water vapor, reducing the temperature of the discharged gas, making the exhaust softer, and preventing the risk of scalding. In addition, an exhaust port 63 is also provided above the overflow tank 6. The exhaust port 63 is arranged at a certain distance from the outlet 12 of the two-way valve device, and the exhaust port 63 is connected to the faucet.

[0028] Refer to the attached Figure 7 , the water vapor generated by the heat storage tank can be discharged into the overflow tank 6 through the exhaust passage b1, and water-vapor separation is carried out in the overflow tank 6. The water generated during separation flows into the overflow tank 6, and the generated gas can be discharged into the atmosphere through the exhaust port 63, thereby effectively realizing water-vapor separation. The heat storage device of the present invention can solve the defect of high-temperature steam spraying from the faucet exhaust port, solve the safety hazard caused by high-temperature steam scalding users, reduce the exhaust temperature, make it softer, and improve the user experience.
