Description

Technical Field

[0001] The utility model relates to the technical field of drinking water equipment, in particular to a water vapor separation device and drinking water equipment using the water vapor separation device. Background Art

[0002] There are many kinds of drinking water equipment in the prior art, such as water dispensers, pipeline dispensers and water purifiers, etc., and in order to meet users' demand for hot water, drinking water equipment on the market basically has a heating function. A large amount of steam will be generated in the process of heating water. In order to prevent steam from scalding users when receiving water, most drinking water equipment is equipped with a water vapor separator to divert hot water and steam.

[0003] However, the existing water vapor separator is prone to incomplete separation of water and steam, which causes part of the steam to be output along with the water flow, resulting in steam spraying. There is a risk of scalding when the user receives water, which affects the safety of the water dispenser. In order to solve this technical problem, a Chinese utility model patent with patent number ZL 202322316537.6 (authorization announcement number CN 220832690U) discloses a water vapor separation device and a water dispenser. The water vapor separation device includes a shell, and the shell is provided with a water inlet pipe, a steam exhaust pipe and a drainage structure. Water enters the shell through the water inlet pipe, and the water in the shell can be discharged through the drainage structure. At least one end of the exhaust pipe extends into the shell, and the height of the end face where the steam inlet end of the exhaust pipe is located gradually decreases in the direction close to the drainage structure, and the steam in the shell is discharged through the exhaust pipe.

[0004] Although the above-mentioned water vapor separation device can gradually reduce the height of the end face where the steam inlet end of the exhaust pipe is located in the direction close to the drainage structure, thereby increasing the steam inlet area of ​​the exhaust pipe, so that the steam in the shell can enter the exhaust pipe more smoothly, so that the steam in the shell can be discharged in time, effectively separating water and steam, and preventing steam from being sprayed out with the water flow through the drainage structure, thereby avoiding scalding accidents when users receive water, and improving the safety of the water dispenser. However, the above-mentioned water vapor separation device discharges the steam in the shell to the external environment through the exhaust pipe, which poses a risk of scalding the user and also causes a certain amount of water resource waste. For this reason, it is necessary to improve the water vapor separation device in the prior art. Utility Model Content

The baffle 5 in this embodiment is substantially perpendicular to the water flow path, as shown in FIG. Figure 5 As shown, the top wall of the baffle 5 in this embodiment is low in the middle and high on both sides. In this way, the hot water entering from the hot water inlet 11 can be automatically directed toward the water outlet 14 through the guide surface 1b, and in the process of hot water flowing, the baffle 5 can optimize the impact force of the water outlet, and alleviate the water hammer effect at the moment of starting the water outlet, making the water outlet flow smoother and more fluent. It can also make the hot water entering from the hot water inlet 11 collide with the baffle 5 to increase the stroke, so that there is enough time for the steam and liquid water to separate and rise, and finally be discharged from the exhaust port 12, so as to prevent high-temperature steam from scalding people and realize the separation of water and steam in the hot water. In addition, Figure 2 As shown, the steam exhaust port 12 is basically located directly above the water outlet 14, the hot water inlet 11 is arranged on the side away from the steam exhaust port 12, and the hot water inlet 11 and the return port 13 are arranged adjacent to each other, so that the water flowing back from the return port 13 to the shell 1 can pass through the guide surface 1b again.

The first collection hood 22 is located above the housing 1, and the second collection hood 23 is located above the first collection hood 22. Figure 2 As shown, each condensation tube in this embodiment is arranged between the first collection cover 22 and the second collection cover 23.

A pipe 221 is arranged toward the exhaust pipe 1a on the bottom wall of the first collecting hood 22. The exhaust pipe 1a is inserted into the pipe 221 and is sealed and connected to the inner peripheral wall of the pipe 221.

[0038] In order to realize the assembly between the second collecting hood 23 and the return port 13, the second collecting hood 23 is in fluid communication with the return port 13 through the first return pipe 4, the first collecting hood 22 is in fluid communication with the first return pipe 4, or the first collecting hood 22 is in fluid communication with the return port 13 through the second return pipe. Figure 2 As shown, the first reflux pipe 4 in this embodiment includes a straight section 41 parallel to the condenser pipe and a curved section 42 assembled with the reflux port 13. The assembly of the outlet of the curved section 42 and the reflux port 13 is also carried out by pipe insertion and sealing connection, which is the same as the assembly method of the exhaust port 12 and the first collecting cover 22, and will not be elaborated here; Figure 3 As shown, the opening of the straight section 41 is located at the bottom of the second collecting cover 23 and passes through the first collecting cover 22 and is connected with the curved section 42. The inlet of the curved section 42 is located at the bottom of the first collecting cover 22. In this way, the liquid water in the second collecting cover 23 and the first collecting cover 22 can be refluxed into the shell 1 through the reflux port 13 through a reflux pipe; of course, two reflux pipes can also be used for separate reflux.
