Abstract
Description
Technical Field
[0001] This utility model relates to the field of commercial water dispensers, and in particular to an energy-saving, continuous-flow hot water commercial water dispenser. Background Technology
[0002] Commercial water dispensers are currently widely used in public places such as train stations, schools, and hospitals. In the past, commercial water dispensers would directly supply hot water from the boiling water tank. When a large amount of hot water was needed, the water in the tank could not reach boiling point in a short time, so people had to wait for the water to boil before they could get hot water. If there were a water dispenser that did not require waiting and could provide hot water at any time, it would undoubtedly bring more convenience and save people time. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides an energy-saving, continuous-flow commercial water dispenser, comprising a body with an internal cavity for accommodating components. The cavity includes a water inlet and a water outlet. The water inlet includes a filter element and a third solenoid valve. When tap water is filtered, the solenoid valve opens, supplying water downwards. The cavity also includes a room-temperature water tank assembly and a boiling water tank assembly. The water in the room-temperature water tank assembly is permanently maintained at a temperature above a set value. The boiling water tank assembly maintains a boiling water temperature and continuously dispenses water. The room-temperature water tank supplies water to the boiling water tank. A steam pipe is installed above the liquid surface in the boiling water tank, leading directly to the upper part of the liquid surface in the room-temperature water tank. When the water in the boiling water tank boils, steam enters the room-temperature water tank through the steam pipe, heating the water. If excessive steam is generated, a vent pipe discharges the steam to a safe location outside the machine.
[0004] Furthermore, the ambient temperature water tank assembly includes an ambient temperature water tank, a first heating element and a first temperature controller installed at the bottom of the inner cavity of the ambient temperature water tank, a first water level switch installed at the upper part of the inner cavity of the ambient temperature water tank, and a vent pipe installed in the ambient temperature water tank that runs from above the liquid surface in the tank to the bottom of the tank. The first water level switch controls the water level at a set safe height, and the first temperature controller controls the operation of the first heating element. When the water temperature in the ambient temperature water tank is lower than the set temperature, the first temperature controller sends a signal to the first heating element, and then the first heating element starts to heat up.
[0005] Furthermore, the hot water tank assembly includes a hot water tank, a second heating element and a second temperature controller installed at the bottom of the inner cavity of the hot water tank, a second water level switch installed at the upper part of the inner cavity of the hot water tank, and a steam pipe installed at the top of the hot water tank. The second water level switch controls the water level at a set safe height, and the second temperature controller controls the operation of the second heating element. When the water temperature in the hot water tank is lower than the set temperature, the second temperature controller sends a signal to the second heating element, and then the second heating element starts to heat up.
[0006] Preferably, the first temperature controller installed in the room temperature water tank controls the water temperature above the set value. When the water temperature is below the set value, the first heating element will start heating. The specific water temperature above the set value depends on the volume of the hot water tank. When the volume is small, the heating is fast and the temperature rises quickly to boiling point. When the volume of the hot water tank is large, the water temperature in the room temperature water tank needs to be increased to facilitate a rapid rise in the water temperature in the hot water tank.
[0007] Preferably, the second temperature controller in the hot water tank controls the water temperature above 98℃. When the temperature is below 98℃, the second heating element will start heating.
[0008] Furthermore, the lower part of the hot water tank is equipped with a water outlet, which is connected to the water intake section by a metal pipeline. A second solenoid valve is also installed at the front end of the water circuit of the water intake section.
[0009] Furthermore, the bottom of the hot water tank and the room temperature water tank are connected by a water pipe, and a first solenoid valve is installed on the water pipe. The water source of the room temperature water tank enters the hot water tank through the first solenoid valve, and the water level of the hot water tank is lower than that of the room temperature water tank.
[0010] Furthermore, the water inlet includes a filter element and a third solenoid valve. The filter element filters the tap water, which then enters the ambient temperature water tank through the third solenoid valve.
[0011] Furthermore, the water dispenser is also equipped with a circuit board, which controls the circuit functions of the entire machine. The circuit board is electrically connected to the solenoid valve, heating element, and thermostat.
[0012] Using the above-mentioned utility model solution, when the water tank is small in size, the water can be heated to boiling quickly, thus maintaining a continuous flow of boiling water. At the same time, the steam in the water tank can be used to heat the water in the room temperature tank, achieving energy-saving and environmentally friendly effects. Compared with conventional water dispensers, it saves the heat exchanger, which not only saves costs but also improves product performance. Attached Figure Description
[0013] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments thereof.
[0014] Figure 1 A schematic diagram of the product structure of this utility model is shown.
[0015] Figure 2 A schematic diagram of the waterway of this utility model is shown. Detailed Implementation
[0016] like Figure 1-Figure 2As shown, the present invention will now be described in detail by way of an embodiment: An energy-saving commercial water dispenser with continuous hot water includes a body 18, the interior of which has a cavity that can accommodate components. The lower part 19 of the cavity is provided with a water inlet, which includes a filter element 2 and a third solenoid valve 3. When the water source 1 is filtered, the third solenoid valve 3 is opened, and the water source 1 supplies water downward. The middle part 20 of the cavity is provided with a water outlet, which is provided with a water spout 17. The upper part 21 of the cavity is also provided with a room temperature water tank assembly and a hot water tank assembly.
[0017] In this embodiment, the ambient temperature water tank assembly includes an ambient temperature water tank 16, a first heating element 22 and a first temperature controller 15 disposed at the bottom of the inner cavity of the ambient temperature water tank 16, a first water level switch 5 disposed at the upper part of the inner cavity of the ambient temperature water tank 16, and a vent pipe 4 disposed in the ambient temperature water tank 16 extending from above the liquid level 26 in the tank to the bottom of the tank. The first water level switch 5 controls the water level at a set safe height. When the liquid level 26 reaches the set height, the first water level switch 5 sends a signal to the circuit board 24, and the circuit board 24 sends an instruction to close the third solenoid valve 3, stopping the water from entering the ambient temperature water tank 16. The first temperature controller 15 controls the operation of the first heating element 22. When the water temperature in the ambient temperature water tank 16 is lower than the set temperature, the first temperature controller 15 sends a signal to the circuit board 24, and the circuit board 24 sends an instruction to the first heating element 22, which then operates to heat up until the set temperature is reached.
[0018] In this embodiment, the hot water tank assembly includes a hot water tank 11, a second heating element 12 and a second temperature controller 10 disposed at the bottom of the inner cavity of the hot water tank 11, a second water level switch 7 disposed at the upper part of the inner cavity of the hot water tank 11, and a steam pipe 6 disposed at the top of the hot water tank 11. The second water level switch 7 controls the water level at a set safe height, and the second temperature controller 10 controls the operation of the second heating element 12. When the water temperature in the hot water tank 11 is lower than the set temperature, the second temperature controller 10 sends a signal. The circuit board 24 sends a signal to the second heating element 12, which then operates and generates heat. A steam pipe 6 is installed above the liquid surface in the hot water tank 11, which leads directly to the upper part of the liquid surface in the ambient temperature water tank 16. When the water in the hot water tank 11 boils, steam enters the ambient temperature water tank 16 through the steam pipe 6 to heat the water in the ambient temperature water tank 16. When the steam exceeds the limit, the steam is discharged to a safe location outside the machine through the vent pipe 4 to prevent an explosion caused by excessive steam.
[0019] In this embodiment, the first temperature controller 15 installed in the ambient temperature water tank 16 preferably controls the water temperature above 20°C. When the temperature is below 20°C, the first heating element will start heating. The specific water temperature above 20°C depends on the volume of the hot water tank. When the volume is small, the heating is fast and the temperature rises quickly to boiling point. When the volume of the hot water tank is large, the water temperature in the ambient temperature water tank needs to be increased to facilitate the water temperature in the hot water tank to quickly reach boiling point. When the temperature exceeds the maximum temperature set by the temperature controller, heating stops.
[0020] In this embodiment, the second temperature controller installed in the hot water tank controls the water temperature above 98°C. When the temperature is below 98°C, the second heating element starts heating; when the temperature is above 100°C, heating stops.
[0021] In this embodiment, a water outlet pipe is also provided at the lower part of the hot water tank 11. The water outlet pipe connects the hot water tank 11 to the water intake part 17. A second solenoid valve 8 is also provided at the front end of the water path of the water intake part 17. When the water intake switch button 9 is pressed, the second solenoid valve 8 is opened, and hot water leaks from the water intake part 17 into the cup.
[0022] In this embodiment, the boiling water tank 11 can permanently maintain the water temperature at boiling point and continuously supply water. The ambient temperature water tank 16 provides water to the boiling water tank 11. The bottoms of the boiling water tank and the ambient temperature water tank are connected by a water pipe 14, and a first solenoid valve 13 is also installed on the water pipe 14. When the water level in the boiling water tank is low, the second water level switch 7 sends a signal, and the first solenoid valve 13 opens and operates, so that the water in the ambient temperature water tank 16 enters the boiling water tank 11, and the water level in the boiling water tank 11 is lower than that in the ambient temperature water tank 16.
[0023] In this embodiment, the water inlet includes a filter element 2 and a third solenoid valve 3. When the power of the water dispenser is turned on and the water level in the room temperature water tank is low, the first water level switch 5 is turned on, which sends a signal to the circuit board. The circuit board then sends a command to the third solenoid valve 3 to open, and the filtered water enters the room temperature water tank.
[0024] In this embodiment, the water dispenser is also equipped with a circuit board 24, which controls the circuit function of the whole machine. The circuit board 24 is electrically connected to the solenoid valve, the heating element, and the thermostat. The circuit board 24 is installed on the back of the door 25 at the bottom of the water dispenser, and the performance of the water dispenser is controlled by the circuit.
[0025] The working principle of this utility model is as follows: When the water level in the ambient temperature water tank is low, the third solenoid valve opens, and water enters the ambient temperature water tank. When the first temperature controller detects that the water temperature in the ambient temperature water tank is below 20°C, it automatically starts heating. When the water level in the boiling water tank is low, the first solenoid valve opens, and ambient temperature water enters the boiling water tank, while the heating function is activated. When the boiling water tank is small, the water can be quickly heated to boiling. When the water temperature reaches the set temperature of 98°C or above, water can be taken out. This keeps the boiling water in a continuous flow state. The steam pipe installed on the top of the boiling water tank can effectively reheat the ambient temperature water, saving energy and heat exchangers, and reducing product costs.
[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
