Description

Technical Field

[0001] This utility model relates to water dispensers, and more particularly to a water dispenser inlet and outlet system. Background Technology

[0002] As an essential appliance in modern living and office environments, there are currently four types of water dispensers commonly used on the market.

[0003] Firstly, bottled water dispensers have two water inlet methods: top-mounted and bottom-mounted. Top-mounted dispensers require manually inverting the bottled water onto the top of the dispenser, allowing water to enter naturally by gravity. Bottom-mounted dispensers place the bottled water at the bottom of the machine, where a built-in pump forces the water into the heating or cooling system. Water dispensing methods include electric and manual dispensing. Electric dispensing involves pressing a button or touch switch to activate the solenoid valve or water pump, while manual dispensing involves pressing a physical tap. Bottled water dispensers require regular bottle replacement, which may pose a risk of secondary contamination. Some models feature intelligent sensor-activated dispensing.

[0004] Secondly, piped water purifiers connect directly to the tap water pipe, and the water enters the storage tank or instant heating module after being filtered by the built-in filter. The water can be dispensed at multiple temperatures, and hot, warm, and cold water can be dispensed instantly by pressing a button through the instant heating module. The water volume can also be set to achieve quantitative water dispensing. Piped water purifiers do not require changing the water tank and can provide a continuous water supply, but the filter needs to be replaced regularly. Some high-end models support APP control of water dispensing.

[0005] Thirdly, tabletop / portable water dispensers require manual water filling, while their water dispensing is mostly electric, supports temperature adjustment, is small in size, requires no installation, and is suitable for mobile scenarios.

[0006] Fourth, the water intake method of the stepping / boiling water dispenser is to connect to the tap water pipe or a large water tank. After passing through multiple stages of filtration, the water enters the heating system. Its water output method is to heat the water to boiling step by step and maintain the water temperature before dispensing. It has a large water output and is suitable for public places such as schools and hospitals.

[0007] However, the water inlet and outlet methods of the above four different water dispensers have drawbacks such as the need to change the water bottle, connect to the tap water pipe, manually fill the water, and connect to a large water tank. In other words, the water dispenser itself cannot realize the water storage function or the automatic water replenishment function, which makes the water dispenser need to interact with the outside world frequently and is cumbersome to operate. Utility Model Content

[0008] The purpose of this invention is to provide a water dispenser inlet and outlet system, which aims to solve the problem that existing water dispensers cannot perform water storage or automatic water replenishment functions, thus requiring frequent interaction with the outside world.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0025] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0026] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0027] Combination Figure 1-10 As shown, this utility model provides a water dispenser water inlet and outlet system, including: a water storage component 1, a heating component 2, a water outlet component 3, a water replenishment component 4, and a water injection component 5. The water storage component 1 is used to store water; the heating component 2 is used to heat the water in the heating component 2; the water outlet component 3 is used to connect to the heating component 2 and control the water to be discharged from the heating component 2; the water replenishment component 4 is used to connect the water storage component 1 and the heating component 2, and detects the water level in the heating component 2, and controls the water storage component 1 to replenish water into the heating component 2 when the heating component 2 is short of water; the water injection component 5 is connected to the water storage component 1 and is used to inject water into the water storage component 1 when the water storage component 1 is short of water.

[0028] In this embodiment of the utility model, by setting a water storage component 1 and a water replenishment component 4, the water dispenser itself can realize the water storage function and the automatic water replenishment function, which reduces the frequency of interaction between the water dispenser and the outside world, realizes the automatic water inlet and outlet of the water dispenser, and is easy to operate.

[0029] Understandably, compared to the existing technology of using bottled water outside the water dispenser, connecting to a tap water pipe or a large water tank 11, or manually adding water, the water storage component 1 can extend the usage time of the water dispenser and facilitate its free movement. When the water replenishment component 4 detects that the heating component 2 is short of water, the water replenishment component 4 controls the water storage component 1 to replenish water into the heating component 2. When there is water in the water storage component 1, the water dispenser can achieve self-circulation without relying on an external water source.

[0030] Secondly, the heating component 2 heats the water inside, providing water at different temperatures for the water dispenser. The water outlet component 3 controls the water flow from the heating component 2. The water inlet component 5 replaces the traditional methods of using bottled water, connecting to a tap, or a large water tank 11, as well as manual water filling. The water inlet component 5 fills the water storage component 1 when it is low on water. Specifically, a sensor is installed inside the water storage component 1 to alert the user when it is low on water, prompting them to fill the water storage component 1 with water via the water inlet component 5. Alternatively, external water sources can automatically fill the water storage component 1 through the water inlet component 5.

[0031] In some embodiments, the water storage component 1 includes: a water tank 11, a first water inlet 12 and a first water outlet 13; the first water inlet 12 is disposed at the top of the water tank 11 and is used to connect to the water injection component 5; the first water outlet is disposed at the bottom of the water tank 11 and is used to connect to the heating component 2.

[0032] In this embodiment, the water tank 11 is used to store water. The first water inlet 12 is located at the top of the water tank 11 and is connected to the water injection component 5, which helps to inject water into the water storage component 1 through the water injection component 5 when the water storage component 1 is short of water. The first water outlet 13 is located at the bottom of the water tank 11 and is connected to the heating component 2, which helps the water replenishment component 4 to control the water storage component 1 to replenish water into the heating component 2 when it detects that the heating component 2 is short of water.

[0033] In some embodiments, the heating assembly 2 includes: a heating tank 21, a water outlet pipe 22, a heating tube 23, and a temperature sensor 24. One end of the heating tank 21 is provided with a second water outlet 25, and the other end is provided with a second water inlet 26 and a vent 27. The second water inlet 26 is used to connect to the first water outlet 13. One end of the water outlet pipe 22 is connected to the second water outlet 25, and the other end is connected to the water outlet assembly 3. The heating tube 23 is connected to the heating tank 21 and is used to heat the heating tank 21. The temperature sensor 24 is attached to the outside of the heating tank 21 and is used to detect the water temperature inside the heating tank 21. When the water temperature inside the heating tank 21 is less than or equal to a first preset temperature, the heating tube 23 is controlled to heat the water temperature inside the heating tank 21 to be greater than or equal to the second preset temperature.

[0034] In this embodiment, the heating tank 21 is provided with a second water outlet 25, a second water inlet 26, and an exhaust port 27. The second water outlet 25 is connected to the water outlet assembly 3 via a water outlet pipe 22, facilitating normal water dispensing from the water dispenser. The second water inlet 26 is connected to the first water outlet 13, enabling the water replenishment assembly 4 to control the water tank 11 to open the first water outlet 13 and replenish water into the heating tank 21 through the second water inlet 26 when the heating tank 21 is detected to be low on water. The temperature sensor 24 is used to detect the water temperature inside the heating tank 21, helping to promptly control the heating tube 23 to heat the water inside the heating tank 21, thereby ensuring the water temperature inside the heating tank 21. The first preset temperature is lower than the second preset temperature; that is, when the water temperature inside the heating tank 21 drops to the first preset temperature, the temperature sensor 24 controls the heating tube 23 to heat the water inside the heating tank 21 until the water temperature reaches the second preset temperature. It is understood that both the first and second preset temperatures are adjustable, and users can set them according to their needs.

[0035] In some embodiments, the heating element 21 has a first opening 28 at the other end. The heating assembly 2 further includes a heat preservation assembly 29, which is used to preserve the heat of the heating assembly 2. The heat preservation assembly 29 includes a base 291, a top cover assembly 292, and a connecting frame 293. The base 291 is disposed at one end of the heating element 21, and the other end of the water outlet pipe 22 passes through and extends out of the base 291. The heating pipe 23 is located between the heating element 21 and the base 291. The top cover assembly 292 is connected to the other end of the heating element 21 and covers the first opening 28. The second water inlet 26 and the exhaust port 27 are opened on the top cover assembly 292. One end of the connecting frame 293 is connected to the base 291, and the other end is connected to the top cover assembly 292. The top cover assembly 292 has a first receiving cavity 294, and a first heat preservation layer 295 is disposed in the first receiving cavity 294. A second receiving cavity 296 is formed between the connecting frame 293, the base 291, and the heating element 21. A second heat preservation layer 297 is disposed in the second receiving cavity 296.

[0036] In this embodiment, the heating tank 21 is provided with a first opening 28, and a second water inlet 26 and an exhaust outlet 27 are provided on the upper cover assembly 292, which helps the heating tank 21 to enter and exit water and exhaust air, so that the heating tank 21 can work normally. The heating tube 23 is used to heat the heating tank 21, and the heating tube 23 is located between the heating tank 21 and the base 291, which can prevent heat loss. Understandably, the upper cover assembly 292 and the base 291 are connected together by the connecting frame 293, sealing the heating element 21 between the upper cover assembly 292 and the base 291, thus achieving a sealing effect on the heating element 21. The upper cover assembly 292 and the base 291 form a structure similar to a thermos cup, which can effectively keep the heating element 21 warm. Moreover, a first insulation layer 295 is provided in the first receiving cavity 294 formed by the upper cover assembly 292, and a second insulation layer 297 is provided in the second receiving cavity 296 formed between the connecting frame 293, the base 291, and the heating element 21, forming an insulation layer similar to a thermos cup. Insulation material is filled in the first insulation layer 295 and the second insulation layer 297, further sealing and keeping the heating element 21 warm, so that the heating element 21 has a good heat preservation effect and does not need to be heated frequently.

[0037] In some embodiments, the water tank 11 is provided with an air inlet 111, and further includes a heating steam self-circulation absorption assembly 14. The heating steam self-circulation absorption assembly 14 is used to connect the heating tank 21 and the water tank 11, and to discharge the heating steam generated by the heating tank 21 into the water tank 11. It includes an exhaust pipe 141, an air inlet pipe 142, a three-way valve 143, and a duckbill one-way valve 144. One end of the exhaust pipe 141 is connected to the exhaust port 27, one end of the air inlet pipe 142 is connected to the air inlet 111, and the three-way valve 143... It includes a first interface 145, a second interface 146, and a third interface 147. The first interface 145 is connected to the other end of the exhaust pipe 141, the second interface 146 is connected to the intake pipe 142, and the other end of the duckbill one-way valve 144 is connected to the third interface 147. When the internal air pressure of the heating tank 21 and the water tank 11 is lower than the preset air pressure, the duckbill one-way valve 144 is opened, and when the internal air pressure of the heating tank 21 and the water tank 11 is higher than or equal to the preset air pressure, the duckbill one-way valve 144 is closed.

[0038] In this embodiment, firstly, the heating tank 21 and the water tank 11 are connected through the exhaust pipe 141, the three-way valve 143, and the air inlet pipe 142. Because the temperature inside the water tank 11 is low, the high-temperature steam generated by the heating tank 21 condenses into liquid upon reaching the water tank 11, thereby reducing the air pressure inside the heating tank 21. Secondly, when excessive liquid is consumed from the heating tank 21, the internal air pressure of the heating tank 21 and the water tank 11 gradually decreases. If the internal air pressure of the heating tank 21 and the water tank 11 falls below atmospheric pressure, there is a risk of them collapsing. The duckbill one-way valve 144 opens when the internal air pressure of the heating tank 21 and the water tank 11 falls below a preset pressure, allowing air to enter the heating tank 21 and the water tank 11, thus balancing the internal air pressure of the heating tank 21 and the water tank 11 with atmospheric pressure, thereby protecting the heating tank 21 and the water tank 11. The heating steam self-circulation absorption device as a whole achieves heating steam self-circulation absorption, solving the problem of existing water dispensers' exhaust causing inconvenience to the driver's cab or poor exhaust performance.

[0039] It is understandable that the water tank 11 has two states: with water and without water. When there is water in the water tank 11, since the water in the water tank 11 is at room temperature, the high-temperature steam generated by the heating tank 21 condenses into liquid after heat transfer when it reaches the water tank 11, thereby reducing the air pressure inside the heating tank 21. When there is no water in the water tank 11, since the water tank 11 has a much larger capacity than the heating tank 21, it is sufficient to hold a large amount of water vapor, thereby ensuring that the air pressure inside the heating tank 21 will not be too high.

[0040] In some embodiments, the water outlet assembly 3 includes: a water outlet pump 31, a water outlet panel device 32, and a third water outlet 33. One end of the water outlet pump 31 is connected to the other end of the water outlet pipe 22 and is used to pump out water from the heating tank 21. The water outlet panel device 32 is disposed on one side of the water storage assembly 1 and is used to control the water outlet pump 31 to output water. The third water outlet 33 is connected to the other end of the water outlet pump 31 and is disposed on the outer side of the water outlet panel device 32.

[0041] In this embodiment, the water pump 31 is used to pump water from the heating tank 21 when the water outlet panel device 32 controls the water dispenser to dispense water. The water in the heating tank 21 flows out through the third water outlet 33, thereby realizing the water dispenser's dispensing of water. The third water outlet 33 is located on the outer surface of the water outlet panel device 32, which helps the user to collect water. The water dispensing principle of the water pump 31 is driven by a prime mover, such as an electric motor, which converts mechanical energy into liquid energy, thereby realizing the lifting and transportation of liquid. This involves the coordinated work of multiple components inside the water pump 31, including the impeller, pump casing, shaft, and bearings, which together constitute the complete working system of the water pump 31.

[0042] In some embodiments, the water outlet panel device 32 includes: a housing 321 and a control panel 322. The housing 321 is disposed on one side of the water storage component 1, and a third water outlet 33 penetrates the housing 321 and is disposed on the outer side of the housing 321. The control panel 322 is disposed on the outer side of the housing 321, and the control panel 322 is provided with a switch button 323, a temperature selection button 324 and a water outlet button 325. The inner side of the housing 321 is provided with micro-touch switches 326 corresponding to the switch button 323, the temperature selection button 324 and the water outlet button 325 respectively. The micro-touch switches 326 are used to connect to the internal functional interface of the water dispenser. The switch button 323 is used to control the water dispenser to turn on or off. The temperature selection button 324 is used to select the temperature of the water outlet from the heating component 2. The water outlet button 325 is used to control the water outlet component 3 to dispense water or stop dispensing water.

[0043] In this embodiment, the water temperature of the water dispenser is selected by a single temperature selection button 324, replacing the hot water button, warm water button and cold water button on the existing water dispenser panel. This controls the water dispenser to dispense hot, warm or cold water. Compared with the existing water dispenser panel, which has too many buttons and makes the panel more cluttered, this improves the user experience.

[0044] It is understood that the housing 321 includes an outer side and an opposite inner side. The user can directly touch the outer side, while the inner side faces the water dispenser body. The micro-touch switch 326 is used to connect to the internal functional interface of the water dispenser. When the switch button 323, temperature selection button 324, and water dispensing button 325 are touched, the corresponding micro-touch switch 326 is activated, thereby controlling the water dispenser to achieve different functions. The third water outlet 33 is used for dispensing water. The third water outlet 33 penetrates through the housing 321 and is located on the outer side of the housing 321, which helps the water inside the water dispenser to be dispensed from the third water outlet 33. Among them, the switch button 323 is used to control the water dispenser to turn on or off, and the water dispensing button 325 is used to control the water dispenser to dispense water or stop water dispensing. These are commonly used function buttons for water dispensers, which are convenient and practical.

[0045] In some embodiments, the temperature selection button 324 includes a first state, a second state, and a third state; when the temperature selection button 324 is in the first state, the micro-touch switch 326 corresponding to the temperature selection button 324 is used to control the third water outlet 33 to output water at the first temperature; when the temperature selection button 324 is in the second state, the micro-touch switch 326 corresponding to the temperature selection button 324 is used to control the third water outlet 33 to output water at the second temperature; when the temperature selection button 324 is in the third state, the micro-touch switch 326 corresponding to the temperature selection button 324 is used to control the third water outlet 33 to output water at the third temperature.

[0046] In this embodiment, the temperature selection button 324 includes a first state, a second state, and a third state. The temperature of the water dispensed by the water dispenser can be selected through the three different states of the temperature selection button 324, which replaces the cold water button, hot water button, and warm water button on the existing water dispenser panel. This controls the water dispenser to dispense water at the first, second, and third temperatures. The first, second, and third temperatures can be adjusted to cold water, warm water, and hot water respectively, which solves the problem of the existing water dispenser panel being too cluttered due to the large number of buttons.

[0047] It is understood that the water dispenser includes a water tank 11 and a heating element 21, as well as a mixing valve (not shown) located between the water tank 11 and the heating element 21. Both the water tank 11 and the heating element 21 are connected to a third water outlet 33. When the temperature selection button 324 is in different states, the mixing valve is in different open and closed states. For example, when the water dispenser dispenses cold water, the mixing valve is closed, and water from the water tank 11 flows to the third water outlet 33. When the water dispenser dispenses hot water, the mixing valve is closed, and water from the heating element 21 flows to the third water outlet 33. When the water dispenser dispenses warm water, the mixing valve is open, and water from the water tank 11 and the heating element 21 flows out simultaneously and then through the mixing valve to the third water outlet 33. After the cold water and hot water are mixed, warm water flows out from the third water outlet 33.

[0048] The three states of the temperature selection button 324 can be changed in the following ways: In one specific embodiment, the temperature selection button 324 is a push-button type. The first state is when the temperature selection button 324 is not pressed; the second state is when the temperature selection button 324 is pressed once; and the third state is when the temperature selection button 324 is pressed twice. The micro-touch switch 326 corresponding to the temperature selection button 324 corresponds to the function interface for the first temperature when the temperature selection button 324 is not pressed, the function interface for the second temperature when the temperature selection button 324 is pressed once, and the function interface for the third temperature when the temperature selection button 324 is pressed twice. In a more specific embodiment, the second temperature is higher than the first temperature, and the third temperature is higher than the second temperature. As the temperature selection button 324 is pressed deeper, the temperature of the water exiting the third outlet 33 gradually increases, helping to prevent accidental scalding from directly dispensing hot water. The push-button type reduces the occurrence of accidental or multiple presses, making it safer and more reliable.

[0049] In another specific embodiment, the temperature selection button 324 is a touch-sensitive button. The first state is when the temperature selection button 324 is not touched; the second state is when the temperature selection button 324 is touched once; and the third state is when the temperature selection button 324 is touched twice. The micro-switch 326 corresponding to the temperature selection button 324 corresponds to the function interface for the first temperature when the temperature selection button 324 is not touched, the function interface for the second temperature when the temperature selection button 324 is touched once, and the function interface for the third temperature when the temperature selection button 324 is touched twice. In a more specific embodiment, the control panel 322 is a touch screen, and the switch button 323, the temperature selection button 324, and the water dispensing button 325 are disposed on the control panel 322. Touch-sensitive buttons are quick and convenient to operate, and can rapidly change the three states of the temperature selection button 324.

[0050] In some embodiments, the water replenishment component 4 includes a water replenishment pump 41 and a liquid level sensor 42. The water replenishment pump 41 is disposed on one side of the heating tank 21 and is used to connect the first water outlet 13 and the second water inlet 26, and to pump water out of the water tank 11. The liquid level sensor 42 is disposed inside the heating tank 21 and is used to detect the water level inside the heating tank 21. When the water level inside the heating tank 21 is less than or equal to the first preset water level, the water replenishment pump 41 is controlled to pump water out of the water tank 11 to replenish the heating tank 21 until the water level inside the heating tank 21 is greater than or equal to the second preset water level.

[0051] In this embodiment, the liquid level sensor 42 is used to detect the liquid level inside the heating tank 21. When the liquid level sensor 42 detects that the heating tank 21 is short of water, the water replenishment pump 41 pumps water from the water tank 11 through the first outlet 13 and into the heating tank 21 through the second inlet 26, replenishing the heating tank 21 in a timely manner. When there is water in the water tank 11, the water dispenser can achieve self-circulation without relying on an external water source. The second preset water level is higher than the first preset water level, and the first and second preset water levels are set according to the actual application scenario of the heating tank 21. Specifically, one end of the liquid level sensor 42 faces one end of the heating tank 21, so that it can accurately detect the liquid level even when the heating tank 21 is short of water and feed the information back to the outside world, which helps to add liquid to the heating tank 21 in a timely manner and prevent damage to the heating tank 21 due to insufficient liquid inside.

[0052] In some embodiments, the water injection assembly 5 includes a connecting pipe 51 and a water injection device 52, one end of the connecting pipe 51 being connected to a water tank 11; the water injection device 52 includes a sliding pipe 521, a second opening 522 and a plug 523, one end of the sliding pipe 521 being slidably inserted into the connecting pipe 51, the second opening 522 being disposed at the other end of the sliding pipe 521, and the plug 523 being detachably connected to the second opening 522.

[0053] In this embodiment, the sliding tube 521 is slidably connected to the connecting tube 51, enabling the sliding tube 521 to be pulled out. The connecting tube 51 connects to the water tank 11. The sliding tube 521 is provided with a second opening 522 for water injection. When water is injected into the water tank 11, the sliding tube 521 is pulled out, and the plug 523 is removed from the second opening 522 to open the second opening 522. Water is injected into the water tank 11 through the second opening 522. After water injection is completed, the plug 523 is connected to the second opening 522, and the sliding tube 521 is pushed back into the connecting tube 51 to reset.

[0054] Understandable, Figure 9 This is a schematic diagram of the water injection component 5 when the water tank 11 is not filled with water. Figure 10 This is a schematic diagram of the structure of the water injection component 5, which pulls out the sliding tube 521 when water is injected into the water tank 11. Since neither the sliding tube 521 nor the connecting tube 51 is folded and is not a flexible tube, there is no water accumulation when water is injected into the water tank 11. The sliding tube 521 is easy to pull out, which shortens the water injection time. Moreover, when water is not needed in the water tank 11, the sliding tube 521 is inserted into the connecting tube 51. When water is needed in the water tank 11, only the sliding tube 521 needs to be pulled out, which ensures that the water injection component 5 is not prone to interference with other functional components.
