[0023] The following is combined with Figure 1-3 This application is described in further detail.

[0024] The present application embodiment discloses a water temperature regulating device for an ultrapure water machine. Figure 1-3 A water temperature regulating device for an ultrapure water machine comprises a housing 1, a normal temperature water tank 3 is installed inside the housing 1, a water inlet pipe 9 is installed at the upper end of the normal temperature water tank 3, the water inlet pipe 9 is connected with the ultrapure water outlet of the ultrapure water machine, ultrapure water is supplied to the normal temperature water tank 3 through the ultrapure water machine, a heating unit 4 and a cooling unit 5 are installed below the normal temperature water tank 3, the ultrapure water is heated and cooled by the heating unit 4 and the cooling unit 5 respectively, and two ultrapure waters of different temperatures are obtained, a distribution component 6 is installed between the bottom of the normal temperature water tank 3, and the distribution component Component 6 includes a four-way pipe 601 installed below the normal temperature water tank 3. A solenoid valve 602 is installed on one side of the four-way pipe 601 close to the heating unit 4 and the cooling unit 5, which is used to supply normal temperature ultrapure water to the heating unit 4 and the cooling unit 5. A mixing component 7 is installed at the lower end of the solenoid valve 602. The two ends of the mixing component 7 are respectively connected to the heating unit 4 and the cooling unit 5. High-temperature ultrapure water, low-temperature ultrapure water and normal temperature ultrapure water can be mixed in proportion as needed to obtain ultrapure water of appropriate temperature, which can reduce the energy consumption required for temperature regulation.

[0025] Reference Figure 3 The heating unit 4 includes a heat preservation barrel 401 for storing high-temperature ultrapure water. A heater 402 is installed inside the heat preservation barrel 401 to heat the ultrapure water entering the heat preservation barrel 401 through the heater 402.

[0026] Reference Figure 2 , including an insulated barrel 501 for storing low-temperature ultrapure water, a spiral cooling water pipe 502 is installed inside the insulated barrel 501, both ends of the cooling water pipe 502 pass through the insulated barrel 501 and the shell 1 and are connected to an external cooling water circulation device, and the ultrapure water entering the insulation barrel 401 is cooled by circulating cooling water through the cooling water pipe 502.

[0027] Reference Figure 3The temperature sensor 10 and the liquid level sensor 11 are installed on the normal temperature water tank 3, the heat preservation barrel 401 and the insulation barrel 501. The temperature is monitored in real time by the temperature sensor 10. When the temperature exceeds the threshold range, the cooling water pipe 502 and the heater 402 are controlled to adjust the temperature. The liquid level is monitored in real time by the liquid level sensor 11. When the liquid level is lower than the temperature threshold range, the corresponding solenoid valve 602 is controlled to operate to supply ultrapure water to the heat preservation barrel 401 or the insulation barrel 501. If the liquid level in the normal temperature water tank 3 is lower than the liquid level threshold range, the ultrapure water machine is controlled to operate to supply ultrapure water to the normal temperature water tank 3.

[0028] Reference Figure 1 An inspection door is installed on the front of the shell 1, and a controller 2 is also installed on the shell 1. The controller 2 is composed of components such as an operation panel, an STM32 series core board, a storage unit, and a power module. The solenoid valve 602, the heater 402, the temperature sensor 10, and the liquid level sensor 11 are all electrically connected to the controller 2.

[0029] Reference Figure 3 The mixing component 7 includes a four-way pipe 701 for collecting ultrapure water of various temperatures. The insulation barrel 401 and the heat-insulating barrel 501 are connected to the corresponding ports of the four-way pipe 601 and the four-way pipe 701 through pipelines respectively. The lower end of the four-way pipe 701 is connected to the water outlet pipe 8. The water outlet pipe 8 is installed with a spiral blade 703. The spiral blade 703 is used to form a spiral flow channel to accelerate the mixing of ultrapure water of different temperatures to form ultrapure water of the required temperature.

[0030] Reference Figure 2 Flow control valves 702 are installed on the three ends of the four-way pipe 701 away from the water outlet pipe 8. The flow control valves 702 are used to accurately control the flow ratio of ultrapure water of corresponding temperature, so as to accurately control the temperature of the mixed ultrapure water. The four-way pipe 1 601 is connected to the four-way pipe 2 701 through a connecting pipe.

[0031] The implementation principle of the water temperature regulating device of an ultrapure water machine in an embodiment of the present application is: first, the ultrapure water produced by the ultrapure water machine flows into the normal temperature water tank 3 through the water inlet pipe 9. The main function of the normal temperature water tank 3 is to store the ultrapure water produced by the ultrapure water machine and serve as the starting point for the subsequent heating and cooling processes.

[0032] The ultrapure water in the normal temperature water tank 3 can be divided into three parts as needed, one part flows into the heating unit 4 through the solenoid valve 602 of the distribution component 6, and the other part flows into the cooling unit 5. The heating unit 4 is provided with a heater 402, and the ultrapure water is heated by the heater 402 to become high-temperature ultrapure water, which is stored in the insulation barrel 401. The cooling unit 5 is provided with a spiral cooling water pipe 502, and both ends of the cooling water pipe 502 pass through the shell 1 and are connected to the external cooling water circulation device. The ultrapure water entering the cooling unit 5 is cooled by the circulating cooling water to become low-temperature ultrapure water, which is stored in the insulation barrel 501.

[0033] During the heating and cooling process, the temperature sensor 10 monitors the water temperature in the heating unit 4 and the cooling unit 5 in real time to ensure that the water temperature is within the set range. If the water temperature exceeds or falls below the set range, the controller 2 adjusts the working state of the heater 402 or the cooling water pipe 502 accordingly to keep the water temperature stable.

[0034] At the same time, the liquid level sensor 11 will monitor the liquid levels in the normal temperature water tank 3, the heating unit 4 and the cooling unit 5 in real time. When the liquid level is lower than the set threshold, the controller 2 will control the solenoid valve 602 of the distribution component 6 to work and add ultrapure water to the heating unit 4 or the cooling unit 5. If the liquid level of the normal temperature water tank 3 is also lower than the set threshold, the controller 2 will control the ultrapure water machine to work and add ultrapure water to the normal temperature water tank 3 through the water inlet pipe 9.

[0035] When the temperature of ultrapure water needs to be adjusted, the controller 2 will accurately control the flow ratio of ultrapure water flowing out of the heating unit 4, the cooling unit 5 and the normal temperature water tank 3 through the flow control valve 702 of the mixing component 7 according to the set temperature and target flow, so as to achieve the mixing of high-temperature ultrapure water with normal-temperature ultrapure water, the mixing of low-temperature ultrapure water with normal-temperature ultrapure water, and the mixing of high-temperature ultrapure water with low-temperature ultrapure water. After these ultrapure waters are mixed through the four-way pipe 701, they enter the water outlet pipe 8 and form a spiral flow channel under the action of the spiral blades 703, thereby accelerating the mixing of ultrapure waters of different temperatures, thereby obtaining ultrapure water of the required temperature.

[0036] In the whole process, the controller 2 plays a key role. It is not only responsible for controlling the working status of the heater 402, the cooling water pipe 502, the solenoid valve 602 and the flow control valve 702, but also responsible for receiving and processing the feedback information of the temperature sensor 10 and the liquid level sensor 11 to achieve precise control of the ultrapure water temperature.
