Description

Technical Field

[0001] This utility model relates to the field of cooling technology for drinking water equipment, specifically to a drinking water equipment with temperature control and cooling function. Background Technology

[0002] In daily life, public places such as high-speed rail stations, bus stations, and hospitals provide large drinking water facilities to facilitate passengers or patients to obtain water at any time. However, most of these facilities currently only provide boiling water close to 100°C and unboiled room temperature water, which cannot meet the needs of most passengers or patients for warm water. In particular, when preparing formula, warm water at the appropriate temperature is required. Moreover, when obtaining boiling water, heat-resistant containers must be used. Ordinary paper cups, plastic cups, and plastic water bottles cannot be used directly, which increases the difficulty for most passengers or patients to prepare warm water. The containers storing boiling water in drinking water facilities generally do not have additional cooling equipment. Usually, the boiling water in the containers is left to cool down naturally, resulting in low cooling efficiency.

[0003] Patent application number 201921744730.7 discloses a cooling system for high-temperature geological tunnels. The system includes a water-guiding and air-guiding device, a water-boiling device, and a gas-heat-dissipating device. The system uses the water-guiding and air-guiding device to introduce cold water into a water pipe. The cold water absorbs heat during its flow and then flows into a boiling tank. The gas-heat-dissipating device uses a pump to continuously extract air from the boiling tank to reduce the pressure inside. After the water is stored in the water-boiling device, the pressure continuously decreases until it reaches its boiling point under low-pressure conditions. The water undergoes a phase change, absorbing a large amount of heat during the boiling process, and is then discharged as water vapor through the air-guiding device. The combined use of the boiling tank, pump, and air-guiding device in this patent document enables the water to undergo a phase change and be discharged as water vapor, thereby achieving the system's cooling function.

[0004] Based on the cooling principle described in the aforementioned public documents, improvements can be made to the existing water storage containers of drinking water equipment to enhance the cooling efficiency of the boiling water in the containers and achieve temperature control and cooling functions.

[0037] like Figures 1 to 6 As shown, this utility model discloses a drinking water device with temperature control and cooling function, including a hot water tank 1, a vacuum pump 2, a temperature measuring module 3, a pressure measuring module 4, and a control module 5. The hot water tank 1 includes a water inlet 11, a water outlet 12, and a first steam outlet 13. The water inlet 11 and the first steam outlet 13 are respectively located at the upper part of the hot water tank 1, and the water outlet 12 is located at the lower part of the hot water tank 1. The vacuum pump 2 includes an air extraction port 21 and an air exhaust port 22. The air extraction port 21 is connected to the first steam outlet 13. The temperature measuring module 3 is used to collect the water temperature in the hot water tank 1, and the pressure measuring module 4 is used to collect the air pressure in the hot water tank 1. The control module 5 is electrically connected to the vacuum pump 2, the temperature measuring module 3, and the pressure measuring module 4 respectively. Based on the physical principle that the phase change process of liquid water into gas absorbs a large amount of heat, the hot water tank 1 is used to hold hot water at a temperature close to 100°C. By controlling the vacuum pump 2 to extract air and water vapor from the hot water tank 1, the internal air pressure of the hot water tank 1 is reduced, causing the hot water to continue to boil and evaporate, thereby improving the cooling efficiency of the hot water tank.

[0038] Specifically, the hot water tank 1 in this embodiment includes a tank body 14 and a cover 15. The cover 15 is located above the tank body 14 and covers the upper opening of the tank body. The cover 15 is detachably connected to the upper opening of the tank body 14 to facilitate periodic cleaning of the inside of the hot water tank 1. The water inlet 11 is located on the rear side wall of the tank body 14 for connecting to an external water inlet pipe. The water outlet 12 is located on the front side wall of the tank body 14 for connecting to a faucet. The first steam outlet 13 is located on the cover 15 and communicates with the inside of the tank body 14. Furthermore, the hot water tank 1 also includes a matching second steam outlet 16 and a pressure relief valve 17. The second steam outlet 16 is located on the cover 15 and communicates with the inside of the tank body 14.

[0039] Continue to refer to Figure 5 and Figure 6A sealing ring 151 is provided at the connection between the cover 15 and the tank body 14 to increase the airtightness of the hot water tank 1. A water-proof cover 152 is provided at the bottom of the cover 15. The interior of the water-proof cover 152 is a cavity with vent holes around it. The bottom is designed to bulge outward to guide the flow. Moreover, the water-proof cover 152 covers the first steam outlet 13 and the second steam outlet 16 to prevent boiling water from being directly sucked into it. The hot water tank 1 also includes a heating mechanism, which is located inside the tank body 14 and is used to boil the water in the hot water tank 1 or to heat and keep it warm.

[0040] This embodiment also includes a three-way vent pipe 6.

It is worth noting that the second steam outlet 16 is located near the exhaust port 22. When the heating mechanism in the hot water tank 1 is working and the internal air pressure is greater than the safety threshold, the pressure relief valve 17 can automatically open, allowing the gas in the hot water tank 1 to be discharged from the second steam outlet 16 and finally from the third port, ensuring the safety of the equipment inside the hot water tank. Preferably, both the inlet 11 and the outlet 12 are equipped with shut-off valves. The hot water tank 1 also includes a check valve 19. The first steam outlet 13 is connected to the exhaust port 21 through the check valve 19, which can prevent the liquefied water in the vacuum pump 2 and the exhaust pipe from flowing back into the hot water tank 1, avoiding contamination of the water in the hot water tank.

[0041] Continue to refer to Figure 1 and Figure 2 In this embodiment, the hot water tank 1 also includes a protective cover 18. The bottom periphery of the protective cover 18 is connected to the cover 15. The vacuum pump 2, the first steam outlet 13, and the second steam outlet 16 are all located inside the protective cover 18. The third port of the three-way air duct 6 passes through the rear side of the protective cover 18. The protective cover 18 mainly serves as a dustproof protection to prevent external factors from interfering with the working environment of the vacuum pump 2. Preferably, this embodiment also includes a mesh cover 9. The mesh cover 9 is configured with an open front end, a closed rear end, and ventilation holes around the perimeter. It is fastened to the outside of the third port of the three-way air duct 6. The front opening is connected to the protective cover 18, and the protective cover 18 is provided with through holes so that the steam discharged from the third port can enter the mesh cover 9. The high-temperature water vapor ejected from the third port of the three-way air duct 6 comes into contact with the rear end of the mesh cover 9 and is discharged from the ventilation holes around the mesh cover 9, preventing the high-temperature water vapor from spraying onto nearby personnel and improving safety.

[0042] In addition, this embodiment also includes a water level gauge 7 and a display module 8, which are electrically connected to the control module 5. The water level gauge 7 is used to collect the liquid level in the hot water tank 1 so as to replenish hot water in time. The temperature measuring module 3 uses a temperature sensor, the pressure measuring module 4 uses a pressure sensor, and the display module 8 uses a touch screen. The touch screen is located on the front surface of the protective cover 18 and can display the liquid level, water temperature and air pressure data inside the hot water tank 1. It also supports touch adjustment of the target water temperature that needs to be cooled.

[0043] The steps for using a drinking water device with temperature control and cooling function in this embodiment are as follows:

[0044] S1, determine the target value for water temperature control in the hot water tank;

[0045] S2. According to the ideal gas law: PV=nRT, where P is the internal gas pressure, V is the gas volume, n is the number of moles of gas, R is the gas constant, and T is the gas temperature; measure the gas volume V inside the hot water tank, set T as the target value for water temperature control, and calculate the gas pressure inside the hot water tank, which is the preset pressure.
