Description

Technical Field

[0001] This utility model relates to the field of water dispenser technology, and in particular to a water vapor separation and water dispensing structure for an instant hot water dispenser based on dual float linkage. Background Technology

[0002] Most existing instant water dispensers use a gravity-feed structure, which suffers from low flow rates (typically <800ml / min) and the tendency for hot water to vaporize and splash from the spout. Furthermore, traditional solenoid valve control schemes are complex, costly, and prone to aging of seals in high-temperature environments. Leakage from the spout is common after the machine stops (an average of 3 drops), affecting both user experience and hygiene, and the open spout design poses a risk of secondary contamination. Summary of the Invention

[0003] In order to solve the above problems, the purpose of this utility model is to provide a water vapor separation and water dispensing structure for an instant hot water dispenser based on dual float linkage.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A water vapor separation and dispensing structure for an instant hot water dispenser based on dual float linkage includes a water tank and a water vapor separation box. The bottom of the water tank has a water inlet and a water outlet. The water outlet is connected to the water inlet of a heating element via a pipe, and the water outlet of the heating element is connected to the water inlet of the water vapor separation box. Its distinguishing feature is:

[0006] The interior of the water vapor separation box forms a water passage cavity, and the upper end of the water vapor separation box is provided with an exhaust chamber that communicates with the water passage cavity. An exhaust port is constructed at the upper end of the exhaust chamber, and the exhaust port is connected to the upper end of the water tank through an exhaust pipe. A first baffle net is provided between the bottom of the exhaust chamber and the water passage cavity, and an exhaust float is provided inside the exhaust chamber.

[0007] The lower outer side of the water vapor separator box is provided with a water outlet that communicates with the water passage chamber. The lower end of the water outlet is provided with a water dispenser outlet. The inner side of the water outlet forms a water outlet chamber. A second partition net is provided between the upper end of the water outlet and the water passage chamber. A water outlet float is provided inside the water outlet chamber.

[0008] When hot water is dispensed, the water passage chamber is not full of water. The vent float falls and contacts the first partition mesh, opening the vent. Steam passes through the vent pipe into the water tank. The outlet float rises and contacts the second partition mesh, opening the water dispenser outlet to dispense hot water.

[0009] When dispensing low-temperature water, the water in the water passage chamber overflows into the venting chamber, causing the venting float to rise and close the venting port; the water outlet float rises and contacts the second partition mesh, opening the water dispenser's outlet to dispense low-temperature water.

[0010] When the machine is stopped, no water enters the water passage chamber, and the water outlet float falls and blocks the water outlet of the water dispenser.

[0011] Preferably, the venting float and the water outlet float are PE hollow floats.

[0012] Preferably, the upper part of the exhaust chamber is a frustum-shaped cone with a gradually decreasing diameter from bottom to top, and the exhaust port is formed at the center of the upper part of the exhaust chamber. The diameter of the exhaust float is larger than the diameter of the exhaust port.

[0013] Preferably, the lower part of the water outlet is a frustum-shaped cone with a gradually decreasing diameter from top to bottom, and the water outlet of the water dispenser is formed in the center of the lower part of the water outlet. The diameter of the water outlet float is larger than the diameter of the water outlet of the water dispenser.

[0014] Preferably, the lower part of the water vapor separator box, between the water inlet and the water outlet, is configured to be inclined, and the inlet is inclined downwards from the water inlet to the water outlet.

[0015] Preferably, the exhaust pipe is U-shaped and includes a first vertical pipe, a connecting pipe, and a second vertical pipe that are integrally formed and connected in sequence. The first vertical pipe is connected to the exhaust port, the second vertical pipe is connected to the upper end of the water tank, and the connecting pipe is connected to the upper end of the second vertical pipe from the upper end of the first vertical pipe at an angle downward.

[0016] The present invention adopts the above technical solution and has the following beneficial effects:

[0017] ① An exhaust chamber is installed at the top of the water vapor separator, and an exhaust pipe is installed between the exhaust port of the exhaust chamber and the water tank. When high-temperature water is discharged, the water flow rate decreases, the water passage chamber of the water vapor separator is not full of liquid, the exhaust float contacts the baffle mesh, the exhaust port opens, and steam enters the exhaust pipe from the exhaust port into the water tank, eliminating the phenomenon of steam splashing when high-temperature water is discharged, making it safer.

[0018] ② After the machine stops, the liquid level in the water passage chamber drops, and the water outlet float falls to block the water outlet of the water dispenser, solving the problem of dripping water when the machine stops. At the same time, it keeps the water vapor separation box in a closed state, preventing dust and bacteria, making it more hygienic.

[0019] ③ The float mechanism has a simple structure, long service life, good stability, and high reliability.

[0020] ④ When discharging low-temperature water, the water supply flow rate increases, the vent float rises and seals the vent, forming a slight positive pressure, which increases the water discharge speed, improves the water discharge flow rate in the low-temperature section, and enhances energy efficiency.

[0029] like Figures 1-3 The above describes a water vapor separation and water dispensing structure for an instant hot water dispenser based on a dual float linkage. It includes a water tank 1 and a water vapor separation box 2. The bottom of the water tank 1 has a water tank inlet 3 and a water tank outlet 4. The water tank outlet 4 is connected to the water inlet of a heating element via a pipe. The water outlet of the heating element is connected to the water inlet of the water vapor separation box 2. The interior of the water vapor separation box 2 forms a water passage chamber 5. The upper end of the water vapor separation box 2 has an exhaust chamber 6 communicating with the water passage chamber 5. The upper end of the exhaust chamber 6 has an exhaust port 7, which is connected to the upper end of the water tank 1 via an exhaust pipe 8. A first partition net 9 is provided between the bottom of the exhaust chamber 6 and the water passage chamber 5. An exhaust float 10 is provided inside the exhaust chamber 6.

[0030] The lower outer side of the water vapor separation box 2 is provided with a water outlet 11 that communicates with the water passage cavity 5. The lower end of the water outlet 11 is provided with a water dispenser outlet 12. The inner side of the water outlet 11 forms a water outlet cavity 13. A second partition net 14 is provided between the upper end of the water outlet 11 and the water passage cavity 5. A water outlet float ball 15 is provided in the water outlet cavity 13.

[0031] When hot water is dispensed, the water passage chamber 5 is not full of water. The vent float 10 falls and contacts the first partition net 9, opening the vent 7. Steam passes through the vent pipe 8 into the water tank 1. The water outlet float 15 rises and contacts the second partition net 14, opening the water dispenser outlet 12 to dispense hot water.

[0032] When low-temperature water is dispensed, the water in the water passage chamber 5 overflows into the exhaust chamber 6, and the exhaust float 10 floats up to close the exhaust port 7; the water outlet float 15 floats up to contact the second partition net 14 and opens the water dispenser outlet 12 to dispense low-temperature water.

[0033] When the machine stops, no water enters the water passage chamber 5, and the water outlet float 15 falls and blocks the water outlet 12 of the water dispenser.

[0034] In the above technical solution, an exhaust chamber is set at the upper end of the water vapor separator, and an exhaust pipe is installed between the exhaust port of the exhaust chamber and the water tank. When dispensing high-temperature water, the water flow rate is reduced (to 0.5L / min when the heating power is >2000W). The water passage chamber of the water vapor separator is not full of liquid, the exhaust float contacts the baffle mesh, the exhaust port opens, and steam enters the exhaust pipe from the exhaust port into the water tank, eliminating the steam splashing phenomenon when dispensing high-temperature water, making it safer. When dispensing low-temperature water, the water supply flow rate is increased, the exhaust float rises and closes the exhaust port to form a slight positive pressure, increasing the water dispensing speed. The water dispensing speed in the low-temperature section is greater than 1.2L / min (more than 50% higher than the traditional method), improving energy efficiency. After the machine stops, the liquid level in the water passage chamber drops, the water outlet float falls and blocks the water outlet of the water dispenser, solving the problem of dripping when the machine stops. At the same time, the water vapor separator is kept in a closed state, preventing dust and bacteria, making it more hygienic.

[0035] Furthermore, the exhaust float 10 and the outlet float 15 are hollow PE floats. In this technical solution, the exhaust float and the outlet float are hollow PE floats, which are high-temperature resistant plastic floats that can withstand continuous operation at 120℃. Compared with traditional solenoid valve control solutions, they have a simpler structure, longer lifespan, better stability, and higher reliability.

[0036] Furthermore, the upper part of the exhaust chamber 6 is a frustoconical shape with a gradually decreasing diameter from bottom to top, and the exhaust port 7 is formed at the center of the upper part of the exhaust chamber 6. The diameter of the exhaust float 10 is larger than the diameter of the exhaust port 7. In this technical solution, the upper part of the exhaust chamber is frustoconical, and the diameter of the exhaust float is larger than the diameter of the exhaust port, thereby ensuring that the exhaust float is confined in the exhaust chamber, and at the same time facilitating the fit between the exhaust float and the upper part of the frustoconical shape to achieve a seal.

[0037] Furthermore, the lower part of the spout 11 is shaped like a frustum with its diameter gradually decreasing from top to bottom. The water outlet 12 is formed at the center of the lower part of the spout 11, and the diameter of the water outlet float 15 is larger than the diameter of the water outlet 12. In this technical solution, the lower part of the spout is frustum-shaped, and the diameter of the water outlet float is larger than the diameter of the water outlet, thereby ensuring that the vent float is confined within the spout, and facilitating a seal between the water outlet float and the lower part of the frustum.

[0038] Furthermore, the lower part of the water vapor separator 2, between the inlet and outlet 11, is configured to be inclined, and slopes downwards from the inlet to the outlet 11. In this technical solution, the inclined lower part of the water vapor separator facilitates water flow to the outlet, improving water output efficiency.

[0039] Furthermore, the exhaust pipe 8 is U-shaped and includes a first vertical pipe 16, a connecting pipe 17, and a second vertical pipe 18 integrally formed and connected in sequence. The first vertical pipe 16 is connected to the exhaust port 7, and the second vertical pipe 18 is connected to the upper end of the water tank 1. The connecting pipe 17 connects obliquely downward from the upper end of the first vertical pipe 16 to the upper end of the second vertical pipe 18. In this technical solution, the connecting pipe of the exhaust pipe is arranged obliquely downward from the water vapor separation box side towards the water tank to prevent steam from condensing and flowing back in the exhaust pipe, thereby improving exhaust efficiency.

[0040] The working principle of this solution is as follows: In high temperature mode, when the heating power is >2000W, the water flow rate is reduced to 0.5L / min. The vent float contacts the first partition mesh due to the drop in liquid level, opens the vent port to conduct steam into the water tank, maintains the chamber pressure, and balances with the outside. In low temperature mode, the water supply flow rate is increased, the vent float rises, completely seals the vent port to form a slight positive pressure, and the water output speed is increased. Under shutdown protection, the drop in liquid level triggers the sealing of the water output float, and the seal responds quickly to achieve zero leakage.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0042] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
