Description

Technical Field

[0001] The invention relates to the field of commercial water dispensers, and in particular to the field of energy-saving long-flow boiling water type commercial water dispensers. Background Art

[0002] At present, commercial water dispensers are widely used in public places such as stations, schools, and hospitals. In the past, commercial water dispensers often directly supply boiled water from the water tank. When a large amount of boiled water is used, the water in the water tank cannot reach boiled water in a short time due to the large amount. It is necessary to wait for the water to boil before taking water. If there is a water dispenser that does not require waiting and can take boiled water at any time, it will undoubtedly bring more convenience to people and save time. Summary of the invention

[0003] In order to solve the above problems, the present invention provides an energy-saving long-flow boiling water commercial drinking water machine, which includes a body, the interior of the body has a cavity that can accommodate components, a water inlet part and a water intake part are arranged in the cavity, the water inlet part includes a filter element and a third solenoid valve, when the tap water is filtered, the solenoid valve is opened, and the water source supplies water downward, a normal temperature water tank assembly and a boiling water tank assembly are also arranged in the cavity, the water in the normal temperature water tank in the normal temperature water tank assembly permanently maintains a temperature above a set value, the boiling water tank in the boiling water tank assembly can permanently maintain the water temperature in a boiling water state and discharge water uninterruptedly, the normal temperature water tank provides a water source to the boiling water tank, a steam pipe is arranged on the upper part of the liquid surface in the boiling water tank, the steam pipe is directly connected to the upper part of the liquid surface in the normal temperature water tank, when the water in the boiling water tank boils, steam enters the normal temperature water tank from the steam pipe to heat the water in the normal temperature water tank, and when the steam exceeds the amount, the steam is discharged to a safe position outside the machine through an air release pipe.

[0004] Furthermore, the normal temperature water tank assembly includes a normal temperature water tank, and also includes a first heating element and a first thermostat arranged at the bottom of the inner cavity of the normal temperature water tank, and a first water level switch arranged at the upper part of the inner cavity of the normal temperature water tank, and a vent pipe arranged in the normal temperature water tank and extending directly from the top of 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 thermostat controls the operation of the first heating element. When the water temperature in the normal temperature water tank is lower than the set temperature, the first thermostat sends a signal to the first heating element, and then the first heating element operates to generate heat.

[0005] Furthermore, the boiling water tank assembly includes a boiling water tank, a second heating element and a second thermostat arranged at the bottom of the inner cavity of the boiling water tank, a second water level switch arranged at the upper part of the inner cavity of the boiling water tank, and a steam pipe arranged at the top of the boiling water tank. The second water level switch controls the water level at a set safety height, and the second thermostat controls the operation of the second heating element.

[0006] Preferably, the first thermostat provided in the normal temperature water tank controls the water temperature above the set value. When the water temperature is lower than the set value, the first heating element performs heating action. The specific water temperature higher than the set value depends on the volume of the open water tank. When the volume is small, the heating is fast and the temperature rises quickly to the boiling water state. When the volume of the open water tank is large, the water temperature in the normal temperature water tank needs to be increased to facilitate the rapid increase of the water temperature in the open water tank.

[0007] Preferably, the second thermostat provided in the water tank controls the water temperature to be above 98°C. When the water temperature is lower than 98°C, the second heating element generates heat.

[0009] Furthermore, the bottom of the open water tank and the normal temperature water tank are connected by a water pipe, and a first solenoid valve is also provided on the water pipe. The water source of the normal temperature water tank enters the open water tank through the first solenoid valve, and the water level of the open water tank is lower than that of the normal temperature water tank.

[0010] Furthermore, the water inlet part includes a filter element and a third solenoid valve. The filter element filters the tap water and then the tap water enters the normal temperature water tank through the third solenoid valve.

[0011] Furthermore, the water dispenser is also provided with a circuit board, which controls the circuit function of the entire machine, and the circuit board is electrically connected to all electrical components such as the solenoid valve, the heating element, and the thermostat.

[0012] By using the above-mentioned invention scheme, when the volume of the boiling water tank is small, the water can be quickly heated to boiling, so that the water can be kept in a long-flow boiling water state. At the same time, the steam in the boiling water tank can also be used to heat the water in the normal temperature water tank, thereby achieving energy-saving and environmental protection effects. Compared with conventional water dispensers, a heat exchanger is saved, which not only saves costs but also improves product performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 2 A schematic diagram of a waterway of the present invention is shown. DETAILED DESCRIPTION

[0016] like Figure 1-Figure 2As shown, the present invention is now described in detail in the form of an embodiment as follows: an energy-saving long-flow boiling water commercial water dispenser, which includes a body 18, the interior of the body has a cavity that can accommodate components, the lower part 19 of the cavity is provided with a water inlet, the water inlet part 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 intake part, the water intake part is provided with a water outlet 17, and the upper part 21 of the cavity is also provided with a normal temperature water tank assembly and a boiling water tank assembly.

[0017] In this embodiment, the normal temperature water tank assembly includes a normal temperature water tank 16, and also includes a first heating element 22 and a first thermostat 15 arranged at the bottom of the inner cavity of the normal temperature water tank, and a first water level switch 5 arranged at the upper part of the inner cavity of the normal temperature water tank 16, and a vent pipe 4 arranged in the normal temperature water tank 16 and extending directly from the top of 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, so that the normal temperature water tank 16 stops entering water. The first thermostat 15 controls the operation of the first heating element 22. When the water temperature in the normal temperature water tank 16 is lower than the set temperature, the first thermostat 15 sends a signal to the circuit board 24, and the circuit board 24 sends an instruction to the first heating element 22, and the first heating element 22 operates to generate heat 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 thermostat 10 arranged at the bottom of the inner cavity of the hot water tank 11, a second water level switch 7 arranged at the upper part of the inner cavity of the hot water tank 11, and a steam pipe 6 arranged at the top of the hot water tank 11. The second water level switch 7 controls the water level at a set safety height, and the second thermostat 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 thermostat 10 sends a signal. The signal is given to the circuit board 24, and the circuit board 24 simultaneously sends an instruction to the second heating element 12, and then the second heating element 12 operates to generate heat. A steam pipe 6 is provided on the upper part of the liquid surface in the boiling water tank 11, and the steam pipe 6 is directly connected to the upper part of the liquid surface in the normal temperature water tank 16. When the water in the boiling water tank 11 is boiled, the steam enters the normal temperature water tank 16 from the steam pipe 6 to heat the water in the normal temperature water tank 16. When the steam exceeds the amount, the vent pipe 4 is used to discharge the steam to a safe position outside the machine to prevent explosion caused by excessive steam.

[0019] In this embodiment, the first thermostat 15 provided in the normal temperature water tank 16 preferably controls the water temperature to be above 20°C. When the temperature is lower than 20°C, the first heating element performs heating. The specific water temperature higher than 20°C depends on the volume of the boiling water tank. When the volume is small, the heating is fast and the temperature rises quickly to the boiling water state. When the volume of the boiling water tank is large, the water temperature in the normal temperature water tank needs to be increased to facilitate the water temperature in the boiling water tank to quickly reach the boiling water state. When the temperature is higher than the maximum temperature set by the thermostat, the heating is stopped.

[0020] In this embodiment, the second thermostat provided in the water tank controls the water temperature to be above 98°C. When the water temperature is lower than 98°C, the second heating element performs heating action. When the water temperature is higher than 100°C, the heating is stopped.

[0021] In this embodiment, a water outlet pipe is also provided at the lower part of the boiling water tank 11, and the water outlet pipe connects the boiling water tank 11 with 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 opens, and the boiling water leaks from the water intake part 17 into the cup.

[0022] In this embodiment, the boiling water tank 11 can permanently keep the water temperature at boiling water and discharge water uninterruptedly. The normal temperature water tank 16 provides water to the boiling water tank 11. The bottom of the boiling water tank and the normal temperature water tank are connected by a water pipe 14, and a first solenoid valve 13 is also provided 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 starts to operate, and the water in the normal temperature water tank 16 enters the boiling water tank 11, and the water level of the boiling water tank 11 is lower than that of the normal temperature water tank 16.

[0023] In this embodiment, the water inlet part 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 normal temperature water tank is low, the first water level switch 5 is turned on and sends a signal to the circuit board. The circuit board then sends an instruction to the third solenoid valve 3 to open, and the filtered water source enters the normal temperature water tank.

[0024] In this embodiment, the water dispenser is also provided with a circuit board 24, which controls the circuit function of the entire machine. The circuit board 24 is electrically connected to all electrical components such as 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 to control the performance of the water dispenser by circuit.

[0025] The working principle of the present invention is as follows: when the water level in the normal temperature water tank is low, the third solenoid valve is opened, and water enters the normal temperature water tank. When the first thermostat detects that the water temperature in the normal temperature water tank is lower than 20°C, it automatically heats the water. When the water level in the boiled water tank is low, the first solenoid valve is opened, and normal temperature water enters the boiled water tank, and the heating function is started at the same time. When the volume of the boiled 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. In this way, the boiled water can be kept in a long-flow state. The steam pipe arranged on the top of the boiled water tank can effectively perform secondary heating on the normal temperature water, saving energy, while saving heat exchangers and reducing product costs.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
