Description

Technical Field

[0001] The utility model relates to the technical field of liquid heating, in particular to a liquid heater which heats liquid while maintaining pressure. Background Art

[0002] When the pressure applied when the liquid molecules of a liquid are about to transform into gaseous molecules (i.e., vapor pressure) is equal to the ambient pressure, the liquid begins to boil, that is, the higher the ambient pressure, the more heat the liquid needs to make the vapor pressure reach the ambient pressure, and the boiling point of the liquid increases accordingly. In high-altitude environments, the boiling point of water is 80°C-90°C. To heat water to 95°C-100°C, or even above 100°C, the water needs to be pressurized to increase the boiling point of the water. In addition, for carbonated water whose gas solubility is affected by ambient pressure, the solubility of gas in water can be increased by pressurization treatment, so that the gas concentration in carbonated water can be maintained by heating carbonated water under pressure.

[0003] Most of the existing products are water storage heaters. The principle is to store water at room temperature and pressure inside the heater and heat it in a sealed manner. While the water is heated, the ambient pressure increases, thereby increasing the boiling point of the water. Specifically, the closed space inside the water tank continues to heat up due to the continuous heating of the water. The water needs more heat to increase the vapor pressure, so that the vapor pressure equals the ambient pressure to start boiling, thereby increasing the boiling point of the water. Most water storage heaters control the boiling point of the water by limiting the ambient pressure by adjusting the pressure valve. Once the valve fails and the pressure discharge is blocked, it is easy to cause a safety accident. In addition, the pressure bearing capacity of the water storage heater is under great test. If the valve does not discharge the pressure in time and the pressure bearing capacity of the heater is insufficient, an explosion safety accident may occur during the heating process.

[0004] The principle of an overflow heater is that water is heated as it flows through a heat-conducting component. Water is heated as it is used, which not only avoids the problem of excessive environmental pressure caused by exhaust failure, but also avoids the problem of hot water staying in the heater for a long time, which will leave scale inside the heater. However, most existing overflow heaters heat water at normal pressure. The sealing structure of the entire heater can hardly provide sufficient environmental pressure, and it can hardly withstand the vapor pressure generated by water reaching the expected boiling point. Such a heater inputs pre-pressurized water, and liquid leakage may occur during the heating process of the heater, causing safety accidents such as electric leakage. Summary of the invention

[0009] Another advantage of the present invention is that it provides a liquid heater, wherein the structure of the liquid input connector is configured to stably input liquid in a pressurized state, thereby preventing the liquid from being unable to smoothly pass through the liquid input connector to enter the interior of the liquid heater due to excessive liquid pressure.

[0010] Another advantage of the present invention is that it provides a liquid heater, wherein the structure of the liquid output connector is configured to stably output liquid in a pressurized and heated state, thereby avoiding the situation where the liquid gushes out of the liquid output connector due to excessive liquid pressure.

[0011] Another advantage of the present invention is that it provides a liquid heater, wherein the liquid heater is equipped with a first temperature sensor and a second temperature sensor, the first temperature sensor detects the liquid temperature of the liquid inlet, and the second temperature sensor detects the liquid temperature of the liquid outlet, and the temperature sensor is arranged in the pressure-bearing structure of the pressure-bearing body, and the pressure-bearing structure of the pressure-bearing body can ensure that the temperature sensor is fixed with good stability.

The liquid is subjected to over-flow heating in the heating chamber 11 . When the liquid reaches an ideal temperature, the liquid flows to the second pressure-bearing member 22 , and then flows out from the liquid output connector 26 .

[0049] The liquid input connector 25 uses a standard high-pressure resistant connector to connect a high-pressure resistant silicone tube to ensure that the liquid input connector 25 can stably input the liquid under pressure, thereby preventing the liquid from failing to pass through the liquid input connector 25 and enter the first pressure-bearing member 21 due to excessive liquid pressure.

[0053] When the high-pressure resistant silicone braided tube is connected to the output body 261 and passes through the fixing part 262, the part of the high-pressure resistant silicone braided tube connected to the fixing part 262 is squeezed, and the part of the high-pressure resistant silicone braided tube connected to the output body 261 is released, thereby locking the braided structure inside the high-pressure resistant braided silicone tube.

[0054] The number of the fixing parts 262 in the liquid output connector 26 can be two, and the two fixing parts 262 are spaced apart and distributed in the output body 261 .

The first seal 27 fills the gap between the heating wall 14 and the first pressure-bearing component 21 that is connected to the outside world, so as to prevent the liquid from leaking outward at the connection position between the heating wall 14 and the first pressure-bearing component 21 under the influence of pressure when the liquid flows from the first pressure-bearing component 21 to the heating chamber 11.

[0064] The second sealing member 28 is disposed between the heating wall 14 and the second pressure-bearing member 22 , and fills the gap between the heating wall 14 and the second pressure-bearing member 22 that is connected to the outside, thereby enhancing the sealing performance of the liquid heater 100 .
