[0002] In today's precision manufacturing industry, it is crucial to stably control the gas temperature inside the process equipment. Although the clean room environment already has temperature and humidity control functions, its stability often cannot meet the needs of process equipment, so it is usually necessary to equip gas temperature / humidity control equipment to provide a stable process environment.

[0004] The general humidification device configuration includes a water replenishment tank and a heating tank. The two tanks are connected by a connecting pipe to ensure that their water levels remain consistent. The heating tank is usually equipped with an electric heating rod. The water temperature is raised to 100°C through the heating effect of the electric heating rod, thereby generating steam, which will be released into the air to achieve the humidification effect. Once the water in the heating tank is converted into steam, the water replenishment tank will simultaneously replenish water to the heating tank to ensure that the water level in the heating tank always remains stable.

[0005] However, during the water replenishment process of the existing humidifier, the temperature of the water in the tank drops due to the large difference between the temperature of the injected water and the temperature in the humidifier tank, causing the steam generation of the humidifier to change, further leading to humidity fluctuations in the target environment.

[0035] In view of the above-mentioned problems of the prior art, the present application provides a water supply preheating and humidification device, which includes a water replenishment component and a heating component. The water replenishment component includes an end of the water inlet pipe that passes through and is connected to the water replenishment tank, and the liquid level switch is arranged at the end of the water inlet pipe. The heating component includes: a heating tank and a heater. The heating tank is connected to the water replenishment tank, and an exhaust port is arranged on an outer side of the heating tank. A first heat exchange part of the water inlet pipe extends to an inner side of the heating tank, and the heater is arranged on the inner side of the heating tank. This device is used to preheat the replenishment water, further reduce the temperature difference caused by the fluid, and solve the problem of humidity fluctuation during the humidification process of the existing device.

[0036] See also Figure 1 , which is a structural schematic diagram of an embodiment of the present application. As shown in the figure, this embodiment is the first embodiment. This embodiment is a water supply preheating humidification device 1, which includes a water replenishment component 10 and a heating component 20. The water replenishment component 10 provides a water source to the heating component 20 for heating to generate steam, thereby correspondingly regulating the humidity of the external environment.

[0037] See again Figure 1 As shown in the figure, in this embodiment, the water replenishment component 10 includes a water replenishment groove 12, a water inlet pipe 14 and a liquid level switch 16. The water replenishment groove 12 is used to accommodate liquid. One end of the water inlet pipe 14 passes through and connects to the water replenishment groove 12. The liquid level switch 16 is arranged at the end of the water inlet pipe 14. The water inlet pipe 14 provides fluid to the water replenishment groove 12, and the liquid level switch 16 adjusts the flow and switches accordingly.

[0038] Continuing with the above, the heating component 20 includes a heating tank 22 and a heater 24. The heating tank 22 is connected to the water replenishment tank 12. An exhaust port 221 is arranged on an outer side of the heating tank 22. The water inlet pipe 14 is extended to an inner side of the heating tank 22 for heat exchange. The heater 24 is arranged on the inner side of the heating tank 22. The heater 24 is used to heat the fluid in the heating tank 22.

[0039] Continuing from the above, the extended portion of the water inlet pipe 14 can be detoured to form a first heat exchange portion 142 . The first heat exchange portion 142 is extended and disposed on the inner side of the heating tank 22 for heat exchange.

[0040] Continuing from the above, in one embodiment, the water replenishing tank 12 is disposed on one side of the heating tank 22, that is, the water replenishing tank 12 is disposed adjacent to the heating tank 22, and the water replenishing tank 12 and the heating tank 22 can be disposed in the same housing, but not limited thereto.

[0041] Continuing from the above, in one embodiment, the heater 24 is an electric heater (or electric heating tube), but the present invention is not limited thereto.

[0042] Continuing with the above, in one embodiment, the liquid level switch 16 can be a float liquid level switch, which utilizes a float floating on the water surface. When the water level rises, the float rises and causes the water pipe opening to shrink or close. When the water level drops, the float drops and causes the water pipe opening to expand or open, but this is not limited to this.

[0043] See again Figure 1 Also see FIG. 2A to FIG. 2B , Figure 2A Picture to Figure 2B The fluid path diagram of an embodiment of the present application is shown in the figure. In the present embodiment, the other end of the water inlet pipe 14 receives a first fluid C1. The first fluid C1 enters the water inlet pipe 14 from the other end of the water inlet pipe 14. After the first fluid C1 passes through the water inlet pipe 14, the first fluid C1 is heated on the inner side of the first heat exchange portion 142 to form a second fluid C2. The second fluid C2 then enters the inner side of the water replenishment tank 12 through the liquid level switch 16. Storage, after the second fluid C2 passes through the water replenishment tank 12, the second fluid C2 enters the heating tank 22, the heater 24 heats the second fluid C2 to form a hot fluid H1, the hot fluid H1 exchanges heat with the first fluid C1 of the first heat exchange part 142 of the water inlet pipe 14, so that the first fluid C1 is heated to form the second fluid C2, and the hot fluid H1 evaporates to form a gas A1, and the gas A1 is then discharged from the exhaust port 221 to adjust the humidity of the external environment or subsequent devices.

[0044] Continuing from the above, in one embodiment, an overflow port 222 is disposed on the outer side of the heating tank 22. When the water level of the hot fluid H1 inside the heating tank 22 is too high, the hot fluid H1 flows out from the overflow port 222 to prevent the water level inside the heating tank 22 from being too high and causing excessive internal pressure.

[0045] Continuing from the above, in one embodiment, the other end of the water inlet pipe 14 is passed through the outer side of the heating tank 22 so that the water inlet pipe 14 is heat exchanged by the heating tank 22 , but this is not limited thereto.

[0046] Continuing with the above, in one embodiment, the other end of the water inlet pipe 14 is passed through an outer side of the water replenishment tank 12, and the water inlet pipe 14 first enters the water replenishment tank 12 and then passes through the water replenishment tank 12 to the heating tank 22, and heat exchange is performed by the heating tank 22, but this is not limited thereto.

[0047] See also Figure 3, which is a schematic diagram of other components of an embodiment of the present application. As shown in the figure, this embodiment is a second embodiment, which is based on the above-mentioned first embodiment. In this embodiment, the water replenishment component 10 further includes a liquid level sensor 18, and the liquid level sensor 18 is arranged on the inner side of the water replenishment tank 12. The liquid level sensor 18 is used to sense the second fluid C2 inside the water replenishment tank 12 and transmit the sensing signal to the outside, such as the control component, so that personnel can know the water level inside the water replenishment tank 12 with a digital signal. The relationship between other components of this embodiment is the same as that of the above-mentioned first embodiment, so it is not repeated here.

[0048] Continuing from the above, in one embodiment, a drain valve 26 is provided on the outer side of the heating tank 22, and the drain valve 26 is used to discharge the fluid (the hot fluid H1, the second fluid C2) inside the heating tank 22 and the water replenishment tank 12 for personnel to repair, replace parts or clean.

[0049] See also Figure 4 , which is a structural schematic diagram of other embodiments of the present application. As shown in the figure, this embodiment is based on the above-mentioned first embodiment or the second embodiment. This embodiment is the third one. The water replenishment tank 12 of the water replenishment component 10 is arranged on the inner side of the heating tank 22 of the heating component 20. In addition to the water inlet pipe 14, the water replenishment tank 12 can also exchange heat with the heating tank 22, so that the temperature of the second fluid C2 inside the water replenishment tank 12 is close to the temperature of the hot fluid H1 inside the heating tank 22. The other component relationships of this embodiment are the same as those of the above-mentioned first embodiment or the second embodiment, so they are not repeated here.

[0050] Continuing from the above, in one embodiment, the liquid level sensor 18 is correspondingly disposed on the inner side of the water replenishment tank 12 to sense the water level inside the water replenishment tank 12 .

[0051] See also Figure 5 , which is a structural schematic diagram of another embodiment of the present application. As shown in the figure, this embodiment is based on the above-mentioned first embodiment, second embodiment or third embodiment. In this embodiment, the other end of the water inlet pipe 14 is further extended to the inner side of the water replenishment tank 12, and the first fluid C1 enters from the other end of the water inlet pipe 14. The first fluid C1 first exchanges heat with the fluid inside the water replenishment tank 12 for preliminary preheating. The first fluid C1 then exchanges heat with the fluid inside the heating tank 22 for secondary preheating. The temperature difference between the fluids of the water replenishment component 10 and the heating component 20 is reduced in a two-stage preheating manner, thereby reducing changes in the steam generation amount of the device.

[0052] Continuing with the above, in one embodiment, the other end of the water inlet pipe 14 is further detoured to form a second heat exchange portion 144, and the second heat exchange portion 144 is extended to the inner side of the water replenishment tank 12, and the second heat exchange portion 144 is connected to the first heat exchange portion 142. The first fluid C1 enters the second heat exchange portion 144 from the other end of the water inlet pipe 14, and the first fluid C1 first exchanges heat with the fluid inside the water replenishment tank 12 on an inner side of the second heat exchange portion 144 for preliminary preheating. The first fluid C1 then flows to the first heat exchange portion 142 for heat exchange with the fluid inside the heating tank 22 for secondary preheating. The temperature difference between the fluids of the water replenishment component 10 and the heating component 20 is reduced in a two-stage preheating manner, thereby reducing changes in the amount of steam generated by the device.

[0053] In summary, the present application provides a water supply preheating humidification device, in which a water replenishment tank is connected to a heating tank and a water inlet pipe is provided. The water inlet pipe is passed through the inner side of the heating tank to preheat the fluid inside the water inlet pipe. The water inlet pipe then transports the fluid into the water replenishment tank through a liquid level switch, so that the temperature difference between the fluid in the water replenishment tank and the heating tank is reduced. When the heating tank is heated to generate steam, the temperature difference of the fluid entering the water is small, which further reduces the fluctuation caused by the fluid temperature difference and reduces the fluctuation of steam generation. This solves the problem that in the existing device, during the water replenishment process of the humidifier, the temperature difference between the injected water and the temperature in the humidifier barrel tank is too large, which causes the water temperature in the tank to drop, resulting in changes in the steam generation amount of the humidifier, further leading to humidity fluctuations in the target environment.
