Description

Technical Field

[0001] This utility model relates to a water dispenser heating tank, and more particularly to a water dispenser heating tank with a water level alarm. Background Technology

[0002] The heating tank is a crucial component in a water dispenser, connecting the water purification and dispensing systems to store and heat purified water. To prevent the water in the heating tank from evaporating completely during repeated heating processes and causing dry burning, common heating tanks are often equipped with a water level sensor. When the water level drops to a certain level, the sensor is triggered, allowing the water dispenser to react to the low water level and prevent the tank from drying out and causing danger. However, installing a water level sensor within the heating tank significantly increases costs, and the installation and fixing structure also becomes more complex, increasing design and maintenance difficulties.

[0003] Therefore, overcoming the aforementioned shortcomings has become an important issue that urgently needs to be addressed by those skilled in the art. Utility Model Content

[0004] This invention overcomes the shortcomings of the above-mentioned technologies and provides a water dispenser heating tank with a water level alarm.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water dispenser hot water tank with a water level alarm includes a hot water tank body 1, which contains an insulated water storage tank 11. The top of the hot water tank body 1 is provided with an outlet 2 that communicates with the top of the insulated water storage tank 11 for connecting to an external water outlet device. The bottom of the hot water tank body 1 is provided with an inlet 3 that communicates with the bottom of the insulated water storage tank 11 for connecting to an external water purifier device. A solenoid valve 4 is also provided in the water passage between the insulated water storage tank 11 and the inlet 3. A heating tube 5 is provided at the bottom of the insulated water storage tank 11. A water temperature sensor 6 is provided inside the insulated water storage tank 11 and is set at the same height as the water level alarm line of the insulated water storage tank 11.

[0007] Preferably, the top of the hot tank body 1 is also provided with an exhaust port 7 that communicates with the top of the insulated water storage tank 11 for connecting a pressure relief valve.

[0008] Preferably, the water temperature sensor 6 is located higher than the heating tube 5.

[0009] Preferably, the hot tank body 1 is also provided with an anti-dry-burning protection device.

[0010] Specifically, the anti-dry-burning protection device includes a mechanical thermostat 8 installed inside the hot tank body 1 and in direct contact with the bottom of the insulated water storage tank 11.

[0011] Preferably, the mechanical temperature controller 8 is a manually reset type temperature controller.

[0012] Preferably, the side wall of the insulated water storage tank 11 is provided with a vacuum insulation layer 111 or the side wall is filled with insulation material.

[0013] Preferably, the insulated water storage tank 11 further includes an upper end cover 12 disposed at the upper end of the insulated water storage tank 11 and a lower end cover 13 disposed at the lower end of the insulated water storage tank 11. The upper end cover 12 is used to cover and protect the pipeline between the insulated water storage tank 11 and the outlet 2, and the outlet 2 is exposed on the upper end cover 12. The lower end cover 13 is used to cover and protect the solenoid valve 4 and the pipeline between the insulated water storage tank 11 and the inlet 3, and the inlet 3 is exposed on the side wall of the lower end cover 13.

[0014] Preferably, a main control board 9 is also fixed inside the lower end cover 13. The main control board 9 is electrically connected to the solenoid valve 4, the heating tube 5, and the water temperature sensor 6 to receive and output control signals. Heat dissipation holes 131 are provided on the side wall and bottom of the lower end cover 13.

[0015] Preferably, the hot tank body 1 is also equipped with a light alarm and a sound alarm so as to emit light and sound signals when the water level is lower than the water level alarm line.

[0016] Preferably, the water temperature sensor 6 is mounted on the top of a telescopic pole.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This water dispenser's heating tank, by placing the water temperature sensor inside the insulated water tank at the height of the water level alarm line, can indirectly determine whether the water level in the sensor has exceeded the low water level alarm line by observing sudden drops in water temperature, thus determining whether a low water level alarm needs to be issued. This eliminates the need for a separate water level sensor inside the insulated water tank, significantly reducing the costs associated with the design, production, and subsequent maintenance of the heating tank.

[0023] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art:

[0024] like Figures 1 to 4 As shown, a water dispenser hot tank with a water level alarm includes a hot tank body 1, which contains an insulated water storage tank 11. The top of the hot tank body 1 is provided with an outlet 2 that communicates with the top of the insulated water storage tank 11 for connecting to an external water outlet device. The bottom of the hot tank body 1 is provided with an inlet 3 that communicates with the bottom of the insulated water storage tank 11 for connecting to an external water purifier device. A solenoid valve 4 is also provided in the water passage between the insulated water storage tank 11 and the inlet 3. A heating tube 5 is provided at the bottom of the insulated water storage tank 11. A water temperature sensor 6 is provided inside the insulated water storage tank 11 and is set at the same height as the water level alarm line of the insulated water storage tank 11.

[0025] The hot water tank in this case differs from traditional hot water tanks in that it does not require a water level sensor inside the tank while still providing a water level alarm function.

[0026] The water dispenser heating tank in this case includes a main body 1, within which is an insulated water storage tank 11 and an outlet 2 and an inlet 3, both connected to the insulated water storage tank 11. A solenoid valve 4 is also installed between the insulated water storage tank 11 and the inlet 3 to control water intake. The insulated water storage tank 11 contains a heating element 5 and a water temperature sensor 6, with the height of the water temperature sensor 6 being level with the water level alarm line of the insulated water storage tank 11. When the purified water in the insulated water storage tank 11 evaporates and decreases during repeated heating, once the water level exceeds the water level alarm line, the water level also exceeds the water temperature sensor 6. This causes a sudden drop in temperature sensed by the water temperature sensor 6. The water dispenser heating tank in this case indirectly determines whether the water level is below the water level alarm line and thus whether a low water level alarm needs to be issued based on the sudden temperature drop data from the water temperature sensor 6.

[0027] Specifically, a low water level alarm will be triggered when the temperature detected by the water temperature sensor 6 drops by more than 10% within a set time range.

[0028] Preferably, a low water level alarm is triggered when the temperature detected by the water temperature sensor 6 drops by more than 10% within 2 seconds.

[0029] As described above, the water dispenser's heating tank in this case, by setting the water temperature sensor 6 inside the insulated water tank 11 at the height of the water level alarm line, can indirectly determine whether the water level inside the sensor 6 has exceeded the low water level alarm line based on the sudden drop in water temperature, thereby determining whether a low water level alarm needs to be issued. This eliminates the need for a separate water level sensor inside the insulated water tank 11, significantly reducing the design, production, and maintenance costs of the heating tank. The water temperature sensor 6 inside the insulated water tank 11 is a standard feature for the heating tank's basic functions. Indirectly determining the water level through the water temperature sensor 6 only requires adjusting its position to the water level alarm line and coordinating with the corresponding trigger control program, without significantly impacting the design, production, or maintenance costs of the heating tank.

[0030] Specifically, the solenoid valve 4 is normally closed, but opens when water is discharged from the external water outlet device.

[0031] like Figure 1 and Figure 2 As shown, preferably, the top of the hot tank body 1 is also provided with an exhaust port 7 that communicates with the top of the insulated water storage tank 11 for connecting a pressure relief valve. In this way, the water vapor generated by the boiling and evaporation of water in the insulated water storage tank 11 can be prevented from accumulating in the insulated water storage tank 11 and causing the pressure inside the pipe to increase. By connecting the pressure relief valve through the exhaust port 7, the water vapor can be quickly discharged when the pressure inside the tank exceeds the threshold, thereby avoiding damage to the insulated water storage tank 11.

[0032] Specifically, the vent 7 is connected in parallel with the water outlet 2, and the vent 7 is located on a branch of the water outlet 2.

[0033] like Figure 2 As shown, preferably, the water temperature sensor 6 is positioned higher than the heating tube 5. This ensures that the heating tube 5 can efficiently heat the purified water in the insulated water storage tank 11 before the water level exceeds the low water level alarm line. This also prevents the water level from passing the heating tube 5 first and then the water temperature sensor 6 when it drops, which would result in a slower rate of passing the water temperature sensor 6 and affect the accuracy of the water level alarm.

[0034] like Figure 3 and Figure 4 As shown, preferably, the hot tank body 1 is also provided with an anti-dry-burning protection device.

[0035] like Figure 3 and Figure 4As shown, specifically, the anti-dry-burning protection device includes a mechanical thermostat 8 installed inside the main body 1 of the hot tank, which is in direct contact with the bottom of the insulated water storage tank 11. Thus, in extreme cases, when the water in the insulated water storage tank 11 is completely evaporated, more of the heat generated by the heating tube 5 will be transferred to the insulated water storage tank 11 through heat conduction. Since the mechanical thermostat 8 is installed at the bottom of the insulated water storage tank 11 and is in direct contact with it, once dry burning occurs and the temperature of the insulated water storage tank 11 exceeds a certain threshold, the mechanical thermostat 8 will be triggered to disconnect the power supply to the heating tube 5, thereby preventing dry burning.

[0036] like Figure 3 and Figure 4 As shown, preferably, the mechanical thermostat 8 is a manually reset type thermostat. In this way, after dry burning occurs, the user must manually reset the mechanical thermostat 8, which forces the user to check the status of the hot can and further reduces the probability of accidents.

[0037] like Figure 2 As shown, preferably, the side wall of the insulated water tank 11 is provided with a vacuum insulation layer 111 or the side wall is filled with insulation material. In this way, the heat exchange between the insulated water tank 11 and the outside can be reduced through the vacuum insulation layer 111 or the insulation material, thereby achieving the heat preservation function. At the same time, the energy consumption of the heating tube 5 can also be reduced through heat preservation.

[0038] like Figures 1 to 4 As shown, preferably, the insulated water storage tank 11 further includes an upper end cover 12 disposed at the upper end of the insulated water storage tank 11 and a lower end cover 13 disposed at the lower end of the insulated water storage tank 11. The upper end cover 12 is used to cover and protect the pipeline between the insulated water storage tank 11 and the outlet 2, and the outlet 2 is exposed on the upper end cover 12. The lower end cover 13 is used to cover and protect the solenoid valve 4 and the pipeline between the insulated water storage tank 11 and the inlet 3, and the inlet 3 is exposed on the side wall of the lower end cover 13.

[0039] As described above, the upper and lower end caps can effectively protect other components located at the upper and lower ends of the insulated water storage tank 11, preventing these components from being damaged by external impacts. At the same time, the combination of the upper and lower end caps with the insulated water storage tank 11 can also improve the integrity and simplicity of the appearance of the hot water tank.

[0040] Furthermore, the upper cover 12 also covers and protects the pipeline between the exhaust port 7 and the insulated water tank 11, with the exhaust port 7 exposed on the upper cover 12.

[0041] like Figure 3 and Figure 4As shown, preferably, a main control board 9 is also fixed inside the lower end cover 13. The main control board 9 is electrically connected to the solenoid valve 4, the heating tube 5, and the water temperature sensor 6 to receive and output control signals. Heat dissipation holes 131 are provided on the side wall and bottom of the lower end cover 13. In this way, the main control board 9 is also placed inside the lower end cover 13, and heat dissipation holes 131 are provided on the side wall and bottom of the lower end cover 13. This can effectively dissipate the heat generated by the main control board 9 during operation to the outside of the hot tank through the heat dissipation holes 131, and avoid heat accumulation inside the lower end cover 13.

[0042] Furthermore, the anti-dry-burning protection device is also electrically connected to the main control board 9.

[0043] Preferably, the hot tank body 1 is also equipped with a light alarm and a sound alarm so that light and sound signals can be emitted when the water level is lower than the water level alarm line. In this way, when the low water level alarm is triggered, a reminder can be issued through sound and light signals so that users can detect abnormalities in time.

[0044] Preferably, the water temperature sensor 6 is mounted on the top of a telescopic rod. This allows the height of the water temperature sensor 6 to be changed by adjusting the length of the telescopic rod, thereby changing the water level height that triggers the low water level alarm. This enables the low water level alarm to be adjusted according to the user's usage habits, improving the applicability of the hot water tank.

[0045] As stated above, this case protects a water dispenser hot water tank with a water level alarm, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
