Description

Technical Field

[0001] The present invention relates to the technical field of water dispensers, in particular to a water dispenser disinfection method and a water dispenser. Background Art

[0002] For energy-saving water dispensers equipped with warm water storage tanks, how to ensure that the warm water tank and the warm water outlet pipes are sterile and that the drinking water is clean, sterile, hygienic and healthy? The industry generally adopts the method of installing a flow-through ultraviolet sterilizer on the warm water pipe to kill bacteria. This method has two disadvantages for water dispensers with multiple warm water outlets: (1) Because a flow-through ultraviolet sterilizer needs to be installed in front of the outlet of each outlet pipe, the installation is more troublesome; (2) Due to the attenuation and life of ultraviolet rays, the sterilization effect will gradually deteriorate or even become ineffective, but it is difficult to detect that the ultraviolet sterilizer has attenuated or damaged by simply observing its appearance.

[0003] Therefore, there are existing solutions in the art that use ozone generators to generate ozone and disinfect the warm water pipes of water dispensers. Existing methods of using ozone to disinfect the warm water pipes of water dispensers mainly take two forms: First, the ozone generator is usually kept running for a long time during the disinfection process to continuously introduce ozone into the warm water pipes to achieve a sterilization effect. This form of disinfection consumes a lot of energy and is not conducive to energy conservation; second, the ozone generator stops working after the ozone concentration in the warm water tank and warm water pipes reaches a certain value, and the sterilization is carried out by relying on the ozone generated previously. The ozone concentration will gradually decrease during the disinfection process, resulting in poor disinfection effect in the subsequent disinfection and sterilization process. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a water dispenser disinfection method and a water dispenser to solve one or more technical problems existing in the prior art and at least provide a beneficial option or create conditions.

[0005] The solution of the present invention to solve its technical problems is:

[0006] The water dispenser disinfection method comprises the following steps:

[0007] Step a1: Close the warm water connection valve and disconnect the warm water outlet from the warm water tank;

[0008] Step b: The ozone generator continues to work, and the ozone generated by the ozone generator continues to flow into the warm water pipe and the warm water tank;

[0009] Step c: The ozone generator works intermittently, and the ozone generated by the ozone generator intermittently flows into the warm water pipeline and the warm water tank;

[0010] Step d1: The warm water heating element in the warm water tank is heated to heat the warm water in the warm water tank;

[0011] Step e1: Open the warm water connection valve and reconnect the warm water outlet to the warm water tank;

[0012] Step f: The warm water outlet valve is opened, and the warm water in the warm water tank flows out from the warm water outlet nozzle.

[0013] Through the above technical solution, this water dispenser disinfection method primarily increases the ozone concentration within the warm water tank and warm water pipe during the continuous operation phase; while during the intermittent operation phase, it primarily ensures that the ozone concentration within the warm water tank and warm water pipe remains within a certain concentration range. This configuration reduces energy consumption while achieving a better disinfection effect.

[0014] After the disinfection is completed, the water in the warm water tank is heated to accelerate the decomposition of ozone to reduce ozone residue. After the disinfection is completed, the warm water in the warm water tank flows out from the warm water outlet to disinfect the warm water outlet.

[0015] As a further improvement of the above technical solution, the disinfection period of the water dispenser disinfection method is from 2:00 a.m. to 4:00 a.m.

[0016] Through the above technical solution, between 2 a.m. and 4 a.m., people are basically in a deep sleep state and the probability of getting water is low. At this time, the water dispenser can use the idle time for disinfection.

[0017] As a further improvement of the above technical solution, the method further includes step d2: a first water pump pumps the boiled water in the boiled water tank to the warm water tank.

[0018] By adopting the above technical solution, pumping the boiled water to the warm water tank can increase the water temperature in the warm water tank, thereby accelerating the decomposition of ozone.

[0019] As a further improvement of the above technical solution, it also includes step a2: the emergency water valve is opened, and the emergency water tank is connected to the warm water outlet. Step a2 is performed after step a1 or simultaneously with step a1, and step e2: the emergency water valve is closed, and the emergency water tank is disconnected from the warm water outlet. Step e2 is performed before step e1 or simultaneously with step e1.

[0020] Through the above technical solution, since the warm water in the warm water tank 320 contains a certain amount of ozone during the disinfection process, drinking it directly will cause certain adverse effects on the human body. Therefore, if someone takes warm water during the disinfection process, warm water will be taken out from the emergency water tank to avoid discomfort caused by someone taking warm water with ozone and drinking it during the subsequent disinfection process.

[0021] As a further improvement of the above technical solution, the method further includes step a0: a second water pump pumps the warm water from the warm water tank to the emergency water tank, and step a0 is performed before step a1.

[0022] Through the above technical solution, boiling water is added to the emergency water tank before starting disinfection to ensure that ozone-free warm water is provided during the disinfection process.

[0023] As a further improvement of the above technical solution, the method further includes step g: a return water pump pumps the warm water in the emergency water tank to the hot water tank.

[0024] Through the above technical solution, after disinfection is completed, the return water pump pumps the water in the emergency water tank to the open water tank, so that the emergency water tank is emptied, thereby preventing warm water from breeding bacteria, and the water in the emergency water tank can be reused.

[0025] As a further improvement of the above technical solution, the method further includes step h: the emergency disinfection pump pumps the boiled water from the boiled water tank to the emergency water tank, and the boiled water is discharged from the emergency water tank after a period of time.

[0026] Through the above technical solution, boiling water is used to perform high-temperature disinfection on the emergency water tank. After the high-temperature disinfection is completed, the water is directly discharged to prevent the disinfected water from contaminating other water tanks of the water dispenser.

[0027] As a further improvement of the above technical solution, the time period for performing step h is staggered with the disinfection time period of the water dispenser disinfection method.

[0028] A water dispenser, applying any of the above-mentioned water dispenser disinfection methods, wherein the water dispenser comprises:

[0029] A warm water tank equipped with a warm water heating element;

[0030] A warm water pipeline, one end of which is connected to the warm water tank, and the other end of which is provided with a warm water connecting valve, a warm water outlet valve, and a warm water outlet nozzle in sequence; the warm water connecting valve is connected to the warm water tank;

[0031] An ozone generator is connected to the warm water pipeline, and the connection between the ozone generator and the warm water pipeline is arranged on a side of the warm water connecting valve close to the warm water tank.

[0032] Through the above technical solution, energy consumption can be reduced while achieving better disinfection effects.

[0033] As a further improvement of the above technical solution, a water dispenser disinfection method is applied, wherein the water dispenser further comprises:

[0034] a hot water tank connected to the warm water tank via a first water pump;

[0035] An emergency water tank connected to the warm water tank via a second water pump, the emergency water tank also being connected to the hot water tank via an emergency disinfection pump and a return water pump;

[0036] The warm water pipeline is further provided with an emergency water valve, which is arranged between the warm water connecting valve and the warm water outlet valve, and the emergency water valve is connected to the emergency water tank.

[0037] Through the above technical solution, since the warm water in the warm water tank contains a certain amount of ozone during the disinfection process, drinking it directly will cause certain adverse effects on the human body. Therefore, if someone takes warm water during the disinfection process, warm water will be taken out from the emergency water tank to avoid discomfort caused by someone taking warm water with ozone and drinking it during the subsequent disinfection process.

[0038] The beneficial effects of the present invention are: reducing energy consumption and obtaining better disinfection effect.

DETAILED DESCRIPTION

[0043] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interactively without conflicting with each other.

[0044] Reference Figure 1 The water dispenser includes: a warm water tank 320, a boiling water tank 100, an emergency water tank 600, a warm water pipeline 300, an ozone generator 500, a heat exchanger 200, and a cold water circuit 400.

[0045] The cold water circuit 400 is equipped with a water filter 420, a water inlet solenoid valve 430, and a check valve 440. These are arranged sequentially along the water inlet direction and connected by a water pipe. One end of the cold water circuit 400 is connected to a water source 410, which is municipal tap water. The water filter 420 filters the municipal tap water to purify it. The water inlet solenoid valve 430 controls whether the municipal tap water flows into the water dispenser.

[0046] The one-way valve 440 directs water flow from the water source 410 toward the heat exchanger 200 . The one-way valve 440 is used to prevent water from flowing back from the heat exchanger 200 into the cold water circuit 400 .

[0047] The heat exchanger 200 is provided with a hot water pipe and a cold water pipe. Hot water and cold water flow in the hot water pipe and the cold water pipe respectively, and the flow directions of the hot water and the cold water are opposite.

[0048] The cold water pipe is provided with a cold water inlet end and a cold water outlet end. The cold water inlet end is connected to the end of the one-way valve 440 away from the water inlet solenoid valve 430 through a water pipe, and the cold water outlet end is connected to the open water tank 100 through a water pipe.

[0049] The hot water pipe is provided with a hot water inlet and a hot water outlet. The hot water inlet is connected to the hot water tank 100 through a water pipe, and the hot water outlet is connected to the warm water pipeline 300.

[0050] When cold water and hot water flow in the heat exchanger 200, the heat of the hot water can be transferred to the cold water, thereby realizing liquid heat transfer, so that the cold water in the cold water pipe is preheated and the hot water in the hot water pipe is cooled.

[0051] The hot water tank 100 is provided with a hot water heater 110, which is configured as a heating tube and is used to heat the hot water in the hot water tank 100 to boiling. A second water level detection device 120 and a third water level detection device 130 are installed in the hot water tank 100. The second water level detection device 120 and the third water level detection device 130 are installed at the upper and lower ends of the hot water tank 100, with the second water level detection device 120 being located above the third water level detection device 130.

[0052] The second water level detection device 120 and the third water level detection device 130 are respectively used to detect the water level in the hot water tank 100. When the water level in the hot water tank 100 reaches the second water level detection device 120, water intake is stopped, so that the water level in the hot water tank 100 is near a water level at a specific height before heating, so that a sufficient amount of air is left in the hot water tank 100 to avoid the volume expansion of the water in the hot water tank 100 during boiling, resulting in excessive pressure in the hot water tank 100; when the water level in the hot water tank 100 is lower than the third water level detection device 130, water intake is started to avoid the water level in the hot water tank 100 being too low.

[0053] The warm water pipeline 300 includes a main water channel 301 and a branch water channel 302 (in other embodiments, the warm water pipeline 300 can also be set as a single water channel without branches), and the number of branch water channels 302 is set to multiple. Specifically, in this embodiment, the number of branch water channels 302 is set to three, and the three branch water channels 302 are all connected to the main water channel 301.

[0054] The hot water pipeline 300 is installed with a hot water connecting valve 330 , an emergency water valve 390 , a hot water outlet valve 380 and a hot water outlet nozzle 340 in sequence.

[0055] The first water pump 310 and the warm water tank 320 are both installed on the main waterway 301. The number of warm water connecting valves 330, emergency water valves 390, warm water outlet valves 380, and warm water outlet nozzles 340 is equal to the number of branch waterways 302, and the warm water connecting valves 330, emergency water valves 390, warm water outlet valves 380, and warm water outlet nozzles 340 are all installed on the branch waterways 302.

[0056] The first water pump 310, the warm water tank 320, the warm water connecting valve 330, the emergency water valve 390, the warm water outlet valve 380 and the warm water outlet nozzle 340 are arranged in sequence from the end close to the hot water tank 100 to the end farthest from the water tank 100, and the first water pump 310, the warm water tank 320, the warm water connecting valve 330, the warm water outlet valve 380 and the warm water outlet nozzle 340 are connected by water pipes.

[0057] The first water pump 310 is used to pump the boiled water in the boiled water tank 100 to the warm water tank 320 . When the water dispenser is in normal use, the first water pump 310 passes through the heat exchanger 200 during the process of pumping the boiled water in the boiled water tank 100 to the warm water tank 320 .

[0058] The warm water tank 320 is provided with a first water level detection device 350 , which is used to detect the water level in the warm water tank 320 to prevent the water level in the warm water tank 320 from being too high.

[0059] An overflow port 360 is further provided at the upper end of the warm water tank 320 .

[0060] The warm water tank 320 is equipped with a warm water heater 322 and an insulation structure 370. Both the warm water heater 322 and the insulation structure 370 are configured as heating pipes. The insulation structure 370 insulates and heats the warm water stored in the warm water tank 320, maintaining the temperature of the warm water within a certain range, ensuring that the drinker receives warm water within a suitable temperature range. The warm water heater 322 heats the warm water stored in the warm water tank 320. After disinfection, the warm water heater 322 is used to quickly heat the warm water in the warm water tank 320, allowing the ozone in the disinfected warm water tank 100 to quickly decompose into oxygen, thereby preventing ozone residue after disinfection.

[0061] The ozone generator 500 includes a generator and a distributor. The generator generates ozone and the distributor evenly delivers ozone to multiple branch waterways 302. The connection between the ozone generator 500 and the warm water pipeline 300 is set on the side of the warm water connection valve 330 away from the warm water outlet 340.

[0062] The emergency water tank 600 is connected to the warm water tank 320 through the second water pump 610. When the water dispenser starts to disinfect, the second water pump 610 works to pump part of the warm water in the warm water tank 320 to the emergency water tank 600.

[0063] The emergency water tank 600 is connected to the hot water tank 100 through the return water pump 620. After disinfection is completed, the return water pump 620 pumps the water in the emergency water tank 600 to the hot water tank 100, so that the emergency water tank 600 is emptied, preventing warm water from breeding bacteria, and the water in the emergency water tank 600 can be reused.

[0064] The emergency water tank 600 is connected to the boiled water tank 100 through the emergency disinfection pump 630. When the emergency water tank 600 needs to be disinfected, the emergency disinfection pump 630 works to pump the boiled water in the boiled water tank 100 to the emergency water tank 600, thereby achieving high-temperature disinfection of the emergency water tank 600.

[0065] The water from the water source 410 (municipal tap water) of this water dispenser is purified by the water purification filter 420 and then controlled by the water inlet solenoid valve 430 to enter the heat exchanger 200 water inlet pipe and enter the hot water tank 100 for heating. After the water in the hot water tank 100 is heated and boiled, it is quickly cooled to warm boiled water through the heat exchanger 200 and then pumped to the warm water tank 320 by the water pump for storage and insulation.

[0066] When taking warm boiled water, the warm boiled water is output through the warm water pipeline 300, the warm water connecting valve 330, the warm water outlet valve 380 and the warm water outlet nozzle 340.

[0067] Since the environment of the warm water tank 320 and the warm water pipeline 300 is suitable for the growth of microorganisms and bacteria, they need to be disinfected and sterilized regularly.

[0068] This water dispenser is disinfected using a specific water dispenser disinfection method, which includes the following steps:

[0069] Step a0: The second water pump 610 pumps the warm water in the warm water tank 320 to the emergency water tank 600 (first, some of the warm water in the warm boiled water tank 100 is pumped to the emergency water tank 600. Since the warm water in the warm water tank 320 contains a certain amount of ozone during the disinfection process, drinking it directly will cause certain adverse effects on the human body. Therefore, if someone takes warm water during the disinfection process, the warm water will be taken out of the emergency water tank 600 to avoid discomfort caused by someone taking and drinking the ozone-containing warm water during the subsequent disinfection process);

[0070] Step a1: The warm water connection valve 330 is closed, and the connection between the warm water outlet 340 and the warm water tank 320 is disconnected;

[0071] Step a2: The emergency water valve 390 is opened, and the emergency water tank 600 is connected to the warm water outlet 340. Step a2 is performed after step a1 or simultaneously with step a1;

[0072] Step b: The ozone generator 500 continues to operate, and the ozone generated by the ozone generator 500 continues to flow into the warm water pipe 300 and the warm water tank 320;

[0073] Step c: The ozone generator 500 works intermittently, and the ozone generated by the ozone generator 500 flows intermittently into the warm water pipeline 300 and the warm water tank 320;

[0074] Step d1: The warm water heating element 322 in the warm water tank 320 is heated to heat the warm water in the warm water tank 320;

[0075] Step d2: The first water pump 310 pumps the hot water in the hot water tank 100 to the warm water tank 320 (in this step, no water enters the cold water pipe to prevent the cold water from passing through the heat exchanger 200 and causing the hot water to cool down).

[0076] Step e1: The warm water connection valve 330 is opened, and the warm water outlet 340 is reconnected to the warm water tank 320;

[0077] Step e2: The emergency water valve 390 is closed, and the emergency water tank 600 is disconnected from the warm water outlet 340. Step e2 is performed before step e1 or simultaneously with step e1.

[0078] Step f: The warm water outlet valve 380 is opened, and the warm water in the warm water tank 320 flows out from the warm water outlet nozzle 340 (after disinfection is completed, the warm water flows out from the warm water outlet nozzle 340, and the residual ozone can be used to disinfect the warm water outlet nozzle 340).

[0079] Step g: The return water pump 620 pumps the warm water in the emergency water tank 600 to the hot water tank 100;

[0080] Step h: The emergency disinfection pump 630 pumps the boiled water in the boiled water tank 100 to the emergency water tank 600, and the boiled water is discharged from the emergency water tank 600 after a period of time.

[0081] More specifically, the disinfection period of this water dispenser disinfection method is from 2 a.m. to 4 a.m. During the period, people are basically in a deep sleep state and the probability of getting water is low. At this time, the water dispenser can use the idle time for disinfection.

[0082] The time period for performing step h is staggered with the disinfection time period of the water dispenser disinfection method.

[0083] During the continuous operation phase, this water dispenser disinfection method primarily increases the ozone concentration within the warm water tank 320 and the warm water pipe 300; during the intermittent operation phase, it primarily ensures that the ozone concentration within the warm water tank 320 and the warm water pipe 300 remains within a certain concentration range. This arrangement reduces energy consumption while achieving a better disinfection effect.

[0084] This solution incorporates an ozone generator 500 within the water dispenser. The dispenser is programmed to periodically activate the ozone generator 500 to generate ozone. The ozone is then evenly distributed to each branch waterway 302 of the warm water pipeline 300, disinfecting and sterilizing the multiple branch waterways 302 of the warm water. The ozone then flows back through the branch waterways 302 to the warm water tank 320. Ozone, through its redox reaction, disrupts the membrane structure of microorganisms, achieving a rapid sterilization effect. During the disinfection process, the ozone gradually reduces and evaporates, returning to the air through the overflow port 360 of the warm water tank 320. After dissolving in water, ozone quickly converts to oxygen molecules, resulting in no residual ozone after disinfection, which is beneficial to the health of the drinker.

[0085] This design utilizes the rapid sterilization function and automatic volatilization and reduction function of ozone. The built-in program of the water dispenser evenly fills ozone into the warm water pipe 300 and the warm water tank 320 of the water dispenser during the idle time of the water dispenser at midnight for disinfection and sterilization, thereby providing clean, sterile, healthy and hygienic drinking water.

[0086] The program in the ozone generator 500 sets different working periods according to the different water supply periods of each water dispenser. This can ensure that the drinking warm boiled water is free of bacteria and microorganisms, and at the same time ensure that there is no ozone residue when drinking, so that the user can drink clean, hygienic and delicious warm boiled water.

[0087] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
