[0030] The present invention is described in detail below in conjunction with specific embodiments.

[0031] In the present utility model, when directional words appear, they are used to facilitate the description of the utility model and simplify the description, rather than to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present utility model.

[0032] In the present invention, unless otherwise specified and limited, when terms such as "disposed on", "connected" and "connected" appear, these terms should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection; it can be directly connected, or it can be connected through an intermediate medium, or the two elements can be internally connected. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figures 1 to 3 As shown, a fast-boiling water machine includes a water inlet container 20, a heating chamber 30, a first pipeline 21, a second pipeline 22, a third pipeline 23, a water pump 40, a fourth pipeline 24, a first solenoid valve 50 and a second solenoid valve 51.

[0034] The water inlet container 20 is a tubular or cubic container, and is provided with a water inlet connector 26 for connecting to an external drinking water pipeline.

[0035] The heating chamber 30 is a cylindrical structure with both ends closed. The heating chamber 30 is connected to the water inlet container 20 through a first pipeline 21. A hollow heating tube 31 coaxially arranged therewith runs through the interior of the heating chamber 30. A water outlet port 32 and a water inlet port 33 are respectively provided at both ends of the hollow heating tube 31. The water outlet port 32 is connected to the water outlet nozzle 13 through a second pipeline 22. The water pump 40 is connected to the first pipeline 21.

[0036] One end of the third pipeline 23 is connected to the interior of the heating chamber 30 , and the other end of the third pipeline 23 is connected to the water inlet port 33 , and extends out of the water inlet port 33 to communicate with the water inlet container 20 .

[0037] The first electromagnetic valve 50 is connected to the third pipeline 23 between the water inlet port 33 and the water inlet container 20. The fourth pipeline 24 is connected to the heating chamber 30 and the water inlet container 20, and the second electromagnetic valve 51 is connected to the fourth pipeline 24.

[0038] In specific implementation, when the water is started to be discharged, the drinking water is pumped out from the external drinking water pipeline by the water pump 40, and enters the heating chamber 30 from the first pipeline 21 through the water inlet container 20 to be preheated. After the drinking water fills the heating chamber 30, it will enter the hollow heating tube 31 from the water inlet port 33 through the third pipeline 23 for secondary heating, and finally the hot water is delivered through the water outlet port 32 through the second pipeline 22 and the water outlet nozzle 13.

[0039] Among them, the first solenoid valve 50 is a normally open solenoid valve, which will only be closed when it is necessary to heat the water to allow the drinking water to pass through the hollow heating tube 31 for secondary heating and water outlet, and the second solenoid valve 51 is a normally closed solenoid valve, which will only be opened to allow the water in the heating chamber 30 to be discharged to the water inlet container 20 after the water outlet stops and there is too much water in the heating chamber 30, so as to avoid the remaining hot drinking water from being repeatedly heated and boiled.

[0040] When the water outlet is turned off, the water pump 40 stops immediately and the first solenoid valve 50 opens. At this time, the residual water in the third pipeline 23, the inside of the hollow heating tube 31, and the second pipeline 22 immediately flows into the water inlet container 20 through the first solenoid valve 50 channel, thereby ensuring that the water outlet 13 does not drip and the water in each pipeline and the heating chamber 30 is quickly emptied.

[0041] When the heating chamber 30 is preheated, steam is generated or boiling water overflows into the third pipeline 23, and the first solenoid valve 50 is in an open state, and the generated steam or boiling water is guided into the water inlet container 20 through the first solenoid valve 50, while the interior of the hollow heating tube 31 is always in a water-free state.

[0042] In addition, a water outlet is provided at the highest position outside the heating chamber 30, and the water outlet is connected to the third pipeline 23, and a water inlet is provided at the lowest position outside the heating chamber 30, and the water inlet is connected to the first pipeline 21. The positions of the water inlet and the water outlet on the heating chamber 30 are set at a maximum diagonal distance to achieve the purpose of maximizing long-process heat exchange.

[0043] In this embodiment, a control main board (not shown) is also included. The hollow heating tube 31, the water pump 40, the first solenoid valve 50 and the second solenoid valve 51 are electrically connected to the control main board (not shown). Control instructions are issued to the hollow heating tube 31, the water pump 40, the first solenoid valve 50 and the second solenoid valve 51 through the control main board (not shown).

[0044] In addition, the fast-boiling water machine of the utility model also includes an outer shell 10, a water inlet container 20, a heating chamber 30, a water pump 40, a first pipeline 21, a second pipeline 22, a third pipeline 23, a fourth pipeline 24, a first solenoid valve 50, a second solenoid valve 51 and a control main board (not shown) are all arranged inside the outer shell 10.

[0045] The housing 10 is also provided with a control box 11, on which a control panel 12 is provided, the control panel 12 is electrically connected to a control main board (not shown), and a water outlet 13 is provided on the control box 11. By lightly pressing a button on the control panel 12, drinking water is heated and discharged.

[0046] In this embodiment, a flow sensor 211 is provided on the first pipeline 21 between the output end of the water pump 40 and the heating chamber 30 , and the flow sensor 211 is signal-connected to a control main board (not shown).

[0047] During specific implementation, the water pump 40 draws drinking water from the water inlet container 20 through the first pipeline 21, and the drinking water enters the heating chamber 30 after passing through the flow sensor 211. When the flow sensor 211 has no sensing signal, it proves that there is a lack of water in the water inlet container 20 or the water pump 40 is damaged, and a corresponding fault code is displayed on the control panel 12.

[0048] In this embodiment, a liquid level sensor 34 and a pre-temperature sensor 35 are provided on the heating chamber 30, and the liquid level sensor 34 and the pre-temperature sensor 35 are connected to the control main board (not shown) by signals.

[0049] In a specific implementation, the water pump 40 extracts drinking water from the water inlet container 20 through the first pipeline 21, and the drinking water enters the heating chamber 30 after passing through the flow sensor 211. When the liquid level sensor 34 obtains a signal, the water pump 40 automatically stops. When the signal of the liquid level sensor 34 exists, the hollow heating tube 31 is controlled to automatically heat the drinking water in the heating chamber 30. When the pre-temperature sensor 35 detects that the temperature in the heating chamber 30 reaches the set value, the hollow heating tube 31 is controlled to automatically stop heating.

[0050] The liquid level sensor 34 is a water level probe and is disposed at the highest position outside the heating chamber 30 so as to better detect the water level in the induction heating chamber 30 .

[0051] In this embodiment, a temperature sensing element 311 is sleeved on the hollow heating tube 31, and the temperature sensing element 311 is in contact with the inner wall of the heating chamber 30. A temperature limiter 312 connected to the signal of the temperature sensing element 311 is provided on the outside of the heating chamber 30, and the temperature limiter 312 is electrically connected to the control main board (not shown).

[0052] In a specific implementation, if the hollow heating tube 31 in the heating chamber 30 suffers from dry burning, the high temperature of the hollow heating tube 31 is rapidly transferred to the surface of the heating chamber 30 via the temperature sensing element 311. At this time, after the temperature limiter 312 senses, the control main board (not shown) rapidly issues an instruction to disconnect the power supply of the hollow heating tube 31 to prevent dry burning from occurring when the internal volume of the heating chamber 30 is insufficient.

[0053] In this embodiment, a water outlet temperature sensor 313 is provided on the hollow heating tube 31 . The water outlet temperature sensor 313 is arranged close to the water outlet port 32 . The water outlet temperature sensor 313 is signal-connected to a control main board (not shown).

[0054] In specific implementation, when the water outlet switch is turned on by the operator, the hollow heating tube 31 starts to heat normally under the premise that relevant parameters (flow signal, liquid level signal) allow, and at the same time the first solenoid valve 50 becomes closed, the water pump 40 starts to supply water, and the preheated drinking water in the heating chamber 30 enters the interior of the hollow heating tube 31 from the water inlet end of the hollow heating tube 31 through the third pipeline 23, and the strong heat reserve inside the hollow heating tube 31 at this time will further quickly heat the inflowing water to achieve the boiling requirement, and the secondary heated drinking water flows from the water outlet port 32 of the hollow heating tube 31 to the water outlet 13 connected to the fourth pipeline 24, and the outlet water temperature sensor 313 will synchronously display the outlet water temperature on the control panel 12 after sensing the outlet water temperature.

[0055] In this embodiment, a water vapor separation chamber 60 is provided on the second pipeline 22 between the water outlet port 32 and the water outlet nozzle 13 , and a steam outlet pipeline 25 is provided on the water vapor separation chamber 60 , and an end of the steam outlet pipeline 25 is connected to the water inlet container 20 .

[0056] During specific implementation, steam will be generated while the temperature of the water heated in the hollow heating tube 31 rises. If the water vapor is simultaneously delivered at the water outlet 13, the flow rate stability will be poor. Therefore, a water vapor separator is provided on the second pipeline 22 between the water outlet port 32 and the water outlet 13 to ensure the flow rate stability of the drinking water delivered, and the generated water vapor is delivered into the water inlet container 20 through the steam outlet pipeline 25.

[0057] The beneficial effects of the utility model are as follows: drinking water enters the heating chamber 30 through the water pump 40 and is preheated by the outer side of the hollow heating tube 31, and then enters the interior of the hollow heating tube 31 through the third pipeline 23 for secondary heating, which can quickly heat the drinking water to the boiling point, and is sent from the water outlet port 32 of the hollow heating tube 31 to the water outlet nozzle 13 for water discharge, and the remaining drinking water in the hollow heating tube 31 and the heating chamber 30 can be discharged back to the water inlet container 20 through the first solenoid valve 50 and the second solenoid valve 51, so as to avoid the remaining hot drinking water being repeatedly heated and boiled.

[0058] In the above structure, the purpose of preheating the drinking water in the heating chamber 30 to reach the boiling point (the national standard boiling water temperature is defined as 92°C) through rapid secondary heating inside the hollow heating tube 31 can be achieved, which can be fully realized through experimental detection. The relevant tests and parameters are as follows:

[0059] 1. Hollow heating tube power: 220V-3300W

[0060] 2. Heating chamber volume: 365ml

[0061] 3. Preheating temperature preset value: 65℃

[0062] 4. Preheating time: 19S (room temperature 20℃)

[0063] 5. Boiling water time: 2S

[0065] 7. Steady state time: 13S

[0066] 8. Steady-state temperature: 96°C

[0067] 9. Steady state flow rate: 655ml / min

[0068] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
