[0067] Currently, water dispensers and other drinking water devices on the market only provide drinking water for users. However, with more and more families keeping pets, users usually need to purchase pet water dispensers separately. Moreover, pet water dispensers on the market usually require users to change the drinking water for their pets regularly, which is not very convenient. In addition, pet water dispensers take up a certain amount of space in the home environment, which is not convenient for small homes. There is an urgent need for a drinking water device that can meet the drinking needs of both users and pets.

[0068] This application discloses a multifunctional drinking water device that can simultaneously meet the drinking water needs of users and pets. The multifunctional drinking water device is a water purifier, a direct drinking water machine, or a water dispenser.

[0069] Please refer to Figures 1 to 3. In one embodiment of this application, the multifunctional drinking device 10 includes a housing 100, a cooling module 200, a heating module 300, and a pet water bowl 400. The housing 100 extends vertically and has a user drinking area 110 and a pet drinking area 120. The user drinking area 110 is located above the pet drinking area 120. The user drinking area 110 has a drinking spout 111, and the pet drinking area 120 has a pet water outlet 120a. The cooling module 200 is disposed inside the housing 100 and has a constant temperature and humidity control. The room temperature water storage chamber 210 and the cold water storage chamber 220 are connected. The room temperature water storage chamber 210 is connected to the pet water outlet 120a through the pet water outlet pipe 13, and the cold water storage chamber 220 is connected to the drinking water outlet 111 through the first water outlet pipe 11. The heating module 300 is located inside the housing 100. The input port of the heating module 300 is connected to the room temperature water storage chamber 210, and the output port of the heating module 300 is connected to the drinking water outlet 111 through the second water outlet pipe 12. The pet drinking bowl 400 is set corresponding to the pet drinking area 120 and is located below the pet water outlet 120a.

[0070] Specifically, please refer to Figure 1. The housing 100 extends vertically and has an installation space for installing the cooling module 200 and the heating module 300. The housing 100 itself has two parts: a user drinking area 110 and a pet drinking area 120, with the user drinking area 110 located above the pet drinking area 120 for separate use by the user and pet. The user drinking area 110 has a drinking spout 111, and the pet drinking area 120 has a pet water outlet 120a. The drinking spout 111 is used to dispense warm, hot, and cold water. There can be one drinking spout to meet the user's needs for water at different temperatures, or there can be multiple spouts; there is no specific limitation. The pet drinking area 120 has a pet water outlet 120a for dispensing warm water for the pet.

[0071] It should be understood that the pet water bowl 400 is positioned corresponding to the pet drinking area 120 and located below the pet water outlet 120a. The pet water bowl 400 forms a drinking trough to collect water flowing from the pet water outlet 120a for the pet to drink. To facilitate the transportation and installation of the multifunctional water device 10, the pet water bowl 400 can be detachably connected to the housing 100, or it can directly abut against the housing 100; no specific restrictions are placed on this.

[0072] Please refer to Figures 2 and 3. The refrigeration module 200 includes a room temperature water storage chamber 210 and a cold water storage chamber 220. The room temperature water storage chamber 210 is connected to a water source and is used to store room temperature water, i.e., water that has not undergone refrigeration or heating treatment. The water source can be municipal tap water or purified water stored in a sealed container. If the water flowing into the room temperature water storage chamber 210 is municipal tap water, a filter module 800 can be installed upstream of the room temperature water storage chamber 210 to filter the water before it flows into the room temperature water storage chamber 210, thereby improving the taste and health of the drinking water. Details regarding the configuration of the filter module 800 will be provided later and will not be elaborated upon here.

[0073] The ambient temperature water storage chamber 210 is connected to the pet water outlet 120a via the pet water outlet pipe 13. This means that ambient temperature water flowing into the ambient temperature water storage chamber 210 can be directly supplied to the pet through the pet water outlet pipe 13, unaffected by the user's drinking water (cold or hot water), effectively preventing temperature fluctuations that could affect the pet's water temperature. The cold water storage chamber 220 is also connected to the water source. The water in the cold water storage chamber 220 is cooled by the heat exchange component 700. The cold water storage chamber 220 is connected to the drinking water outlet 111 via the first water outlet pipe 11. When the user needs cold water, the water in the cold water storage chamber 220 can flow out through the first water outlet pipe 11. The heat exchange component 700 can be integrated into the cooling module 200, or it can be a separate component used to cool the water in the cold water storage chamber 220; there are no specific limitations on this.

[0074] Regarding the connection method between the cold water storage chamber 220 and the water source, it can be directly connected to the water source through a water interface, or indirectly connected through the ambient temperature storage chamber 210. When the cold water storage chamber 220 is indirectly connected to the water source through the ambient temperature storage chamber 210, the method can be to set a flow divider in the refrigeration module 200. Through the function of the flow divider, the interior of the refrigeration module 200 is divided into the isolated ambient temperature storage chamber 210 and the cold water storage chamber 220. The ambient temperature storage chamber 210 is directly connected to the water source. The flow divider is provided with a connecting flow path, and the cold water storage chamber 220 is connected to the ambient temperature storage chamber 210 through the connecting flow path, thereby achieving connection with the water source. In this embodiment, in order to reduce the number of pipes upstream of the refrigeration module 200 and the number of water interfaces of the refrigeration module 200 itself, the cold water storage chamber 220 is connected to the water source indirectly.

[0075] Please refer to Figures 2 and 3. The heating module 300 is housed within the casing 100. The input port of the heating module 300 is connected to the ambient temperature water storage chamber 210, and the output port of the heating module 300 is connected to the drinking water outlet 111 via the second water outlet pipe 12. The heating module 300 typically has a heating state and a non-heating state. When the heating module 300 is in the heating state, the ambient temperature water in the ambient temperature water storage chamber 210 flows into the heating module 300 through the input port for heating and then flows through the second water outlet pipe 12 to the drinking water outlet 111 for the user to drink. When the heating module 300 is in the non-heating state, the ambient temperature water in the ambient temperature water storage chamber 210 flows through the heating module 300 and through the second water outlet pipe 12 to the drinking water outlet 111 for the user to drink, and the water flowing out at this time is ambient temperature water. In this way, the user's needs for both hot water and ambient temperature water can be met.

[0076] It should be noted that the terms "inlet" and "inlet side" mentioned above and below refer to the side where water flows in, and similarly, "outlet" and "outlet side" refer to the side where water flows out.

[0077] The water flowing into the ambient temperature water storage chamber 210 can also be supplied through an inlet pipe 15 within the multifunctional drinking water device 10. The ambient temperature water storage chamber 210 is connected to the water source via the inlet pipe 15. Since the cold water storage chamber 220 is indirectly connected to the water source through the ambient temperature water storage chamber 210, only one inlet pipe 15 is provided in this embodiment, simplifying the pipe layout. The pet water outlet pipe 13 is connected to the ambient temperature water storage chamber 210. This simplifies the pipe layout within the housing 100 and shortens the length of the pet water outlet pipe 13. Because the pet water outlet pipe 13 is directly connected to the ambient temperature water storage chamber 210, it is not affected by cold or hot water when the pet drinks, ensuring that the pet can drink water at a suitable temperature.

[0078] The technical solution of this application provides a user drinking area 110 and a pet drinking area 120 on the housing 100. The refrigeration module 200 has a room-temperature water storage chamber 210 and a cold water storage chamber 220. The pet drinking area 120 has a pet water outlet 120a, which is connected to the room-temperature water storage chamber 210 of the refrigeration module 200 via a pet water outlet pipe 13, allowing room-temperature water to flow directly to the pet without being affected by hot or cold water. This achieves the function of simultaneously providing drinking water and pet water for both the user and pet, integrating these two functions into one, meeting diverse user needs, facilitating user operation, and also improving the utilization of home space.

[0079] In one embodiment, please refer to Figures 2 and 3. The cooling module 200 is located above the heating module 300. The cooling module 200 is provided with a normal temperature output port 230 that communicates with the normal temperature water storage chamber 210. The water system also includes a connecting pipe 14. The input port of the heating module 300 and the normal temperature output port 230 are connected through the connecting pipe 14.

[0080] Specifically, a connecting pipe 14 can be installed between the cooling module 200 and the heating module 300 to allow water in the ambient temperature water storage chamber 210 to flow into the heating module 300 through the connecting pipe 14, and then flow out to the drinking water outlet 111 for user use via the second water outlet pipe 12. The cooling module 200 has an ambient temperature output port 230 connected to the ambient temperature water storage chamber 210. One end of the connecting pipe 14 is connected to this ambient temperature output port 230, and the other end is connected to the output port of the heating module 300. By placing the cooling module 200 above the heating module 300, the water in the ambient temperature water storage chamber 210 can flow to the heating module 300 for heating under gravity, eliminating the need for a separate booster pump to pressurize the water system in the multi-functional drinking water device 10. This eliminates a component, reduces the cost of the multi-functional drinking water device 10, and simplifies assembly.

[0081] In one embodiment, referring to Figures 2 and 3, one end of the pet water outlet pipe 13 is connected to the connecting pipe 14, and the other end is connected to the pet water outlet 120a. Specifically, to reduce the number of water interfaces of the cooling module 200, one end of the pet water outlet pipe 13 is directly connected to the connecting pipe 14, thereby achieving communication with the ambient temperature water storage chamber 210, so that water in the ambient temperature water storage chamber 210 can flow out through the pet water outlet pipe 13 for the pet to drink.

[0082] In one embodiment, referring to Figures 2 and 3, the multifunctional drinking device 10 also includes a water outlet valve 510. The water outlet valve 510 is located in the pet water outlet pipe 13 and near the pet water outlet 120a, and is used to control the opening and closing of the pet water outlet pipe 13. Specifically, the user can control the opening and closing of the water flow in the pet water outlet pipe 13 by controlling the water outlet valve 510, thereby replenishing water when the water level in the pet water bowl 400 is insufficient. The water outlet valve 510 can be a manual valve, allowing direct water replenishment to the pet water bowl through manual control; alternatively, the water outlet valve 510 can be a solenoid valve, controlled by a water outlet switch electrically connected to it, thereby replenishing water to the pet water bowl. In this embodiment, the water outlet switch valve 510 is configured as a solenoid valve and is located close to the pet water outlet 120a. This avoids the distance between the water outlet switch valve 510 and the pet water outlet 120a being too long, making it difficult to accurately determine the water volume and causing the pet water bowl 400 to overflow.

[0083] Further, referring to Figure 1, the multi-functional drinking device 10 is equipped with a pet water dispensing switch 520, which is electrically connected to a solenoid valve. Thus, by operating the pet water dispensing switch 520, water can be dispensed from the pet water outlet 120a, facilitating user operation. The pet water dispensing switch 520 can be a touch switch or a mechanical switch.

[0084] Furthermore, the pet water outlet switch 520 is located on the housing 100 and above the user drinking area 110. This design prevents the pet from accidentally activating the switch and causing continuous water flow, thus avoiding overflow of the pet water bowl 400. In this embodiment, the pet water outlet switch 520 is configured as a mechanical push-button switch. The water flow from the pet water outlet 120a is controlled by a logic of pet water outlet switch 520 + water outlet valve 510. That is, pressing the pet water outlet switch 520 sends a command to it, which then controls the opening and closing of the water outlet valve 510, thus replenishing water in the pet water bowl 400. Manual control effectively prevents overflow.

[0085] In one embodiment, referring to Figure 4, the multifunctional drinking water device 10 also includes a one-way valve 600. The one-way valve 600 is disposed in the connecting pipe 14 and near the inlet of the heating module 300 to prevent hot water from flowing back into the heating module 300. Specifically, during the heating process of the heating module 300, due to thermal expansion and contraction, some hot water will flow back into the connecting pipe 14, affecting the water temperature. This can cause the water temperature at the pet water outlet pipe 13 connected to the connecting pipe 14 to be too high. Therefore, a one-way valve 600 is installed between the inlet of the pet water outlet pipe 13 and the inlet of the heating module 300 to prevent the hot water generated during the heating process of the heating module 300 from flowing back, thus meeting the requirement of stable pet drinking water temperature.

[0086] In one embodiment, the pet water bowl 400 is snap-fitted, magnetically connected, or abutted against the housing 100. Specifically, to facilitate the transportation and installation of the multifunctional water device 10, the pet water bowl 400 is detachably connected to the main body of the multifunctional water device 10. In use, the pet water bowl 400 can be directly used as a separate component, abutting against the housing 100 and located below the pet water outlet 120a. Of course, to prevent pets from running around the house or users from accidentally kicking the pet water bowl 400, the pet water bowl 400 and the housing 100 are connected by snap-fitting or magnetic connection to further ensure that the position of the pet water bowl 400, located in the pet drinking area 120 and below the pet water outlet 120a, does not shift.

[0087] In one embodiment, the ambient temperature water storage chamber 210 and / or the cold water storage chamber 220 have a full water level line, which is located above the drinking water outlet 111. Specifically, the ambient temperature water storage chamber 210 or the cold water storage chamber 220 has a full water level line, which means that the water level in the ambient temperature water storage chamber 210 or the cold water storage chamber 220 is higher than the water level line of the drinking water outlet 111. This arrangement ensures that the water in the ambient temperature water storage chamber 210 or the cold water storage chamber 220 can be transported throughout the entire water circuit of the multifunctional drinking water device 10 through the water level difference, without the need for a separate booster pump.

[0088] In one embodiment, referring to Figures 1 to 4, the drinking water outlet 111 includes a first outlet 111a and a second outlet 111b. The cold water storage chamber 220 is connected to the first outlet 111a via a first outlet pipe 11, and the output port of the heating module 300 is connected to the second outlet 111b via a second outlet pipe 12. Specifically, there are two drinking water outlets 111, corresponding to the first outlet pipe 11 and the second outlet pipe 12 respectively. In this embodiment, the first outlet 111a and the second outlet 111b use a mechanical switch to dispense water.

[0089] In one embodiment, referring to Figure 4, the multifunctional drinking water device 10 further includes a heat exchange component 700. The heat exchange component 700 includes an evaporator 710 and a condenser 720 connected to each other. The evaporator 710 is disposed corresponding to the cold water storage chamber 220 of the refrigeration module 200 to cool the water in the cold water storage chamber 220, and the condenser 720 is used to dissipate heat. Specifically, in this embodiment, the refrigeration module 200 cools the water in its cold water storage chamber 220 through the heat exchange component 700. The heat exchange component 700 includes an evaporator 710, a condenser 720, a compressor 730, and a capillary tube 740 (or an electronic expansion valve 740). The evaporator 710 can be fitted onto the outer wall of the refrigeration module 200 and is disposed corresponding to the position of the cold water storage chamber 220 to cool the water in the cold water storage chamber 220.

[0090] In one embodiment, referring to Figure 4, the water system further includes an exhaust branch 16, which connects the heating module 300 and the ambient temperature water storage chamber 210. Specifically, the exhaust branch 16 is used to exhaust the hot steam generated by the heating module 300 during operation to the ambient temperature water storage chamber 210, so as to ensure that the gas does not flow out from the second water outlet pipe 12 and to ensure the stability of the hot water output.

[0091] In one embodiment, referring to Figure 4, the water system also includes a drainage branch 17, which is connected to the heating module 300. When the user does not use the multi-functional drinking water device 10 using this water system for a long time, the water in the entire water system can be drained through the drainage branch 17, that is, the water in the cooling module 200 and the heating module 300 can be drained.

[0092] In one embodiment, referring to Figure 4, the water system further includes a filter module 800, which is disposed in the inlet pipe 15. Specifically, when the inlet pipe 15 is directly connected to municipal water, the filter module 800 needs to be installed upstream of the cooling module 200 to filter the municipal water, which then flows into the ambient temperature water storage chamber 210 and the cooling water storage chamber of the cooling module 200, and flows out through the first outlet pipe 11, the second outlet pipe 12 and the pet outlet pipe 13 respectively for drinking by the user and the pet.

[0093] Furthermore, the filter module 800 includes a first filter element 810 and a second filter element 820. The first filter element 810 is made of PP, and the second filter element 820 is made of activated carbon. Specifically, the main material of the first filter element 810 is polypropylene (PP), which has high filtration accuracy, small size, and large filtration area. PP cotton filter elements can effectively filter impurities in water, such as sediment, rust, and suspended solids, making the water clearer and more transparent; they can also remove odors from the water, such as chlorine and foul smells, improving the taste and quality of the water; and they have a certain antibacterial ability, which can effectively prevent bacteria from growing inside the filter element and ensure the hygiene and safety of the water; at the same time, as a pre-filter element of drinking water (water purification) equipment, it can effectively protect subsequent filter elements and equipment, preventing impurities and contaminants from entering subsequent filter elements and equipment, thereby extending the service life of the equipment; and PP cotton filter elements have a long service life and low maintenance costs, which helps to reduce the operating and maintenance costs of the equipment. The second filter element 820 is made of activated carbon. Due to its porous structure, activated carbon has an extremely large specific surface area, with each gram of activated carbon having a surface area of ​​500–1500 m². 2 It can efficiently adsorb organic matter, residual chlorine, odors, colors, and other radioactive substances in water. Furthermore, the activated carbon filter effectively removes harmful substances and odors such as formaldehyde, benzene, and ammonia, significantly improving water quality. The dual-filter setup further enhances water filtration, thereby improving the health and safety of water for users and pets.

[0094] In one embodiment, referring to Figure 4, the water system is further provided with an inlet solenoid valve 910, which is located in the inlet pipe 15. That is, the inlet solenoid valve 910 is located upstream of the refrigeration module 200. The inlet solenoid valve 910 can be used to control the flow of water to the ambient temperature water storage chamber 210 of the refrigeration module 200. When the water volume in the ambient temperature water storage chamber 210 is insufficient, the inlet solenoid valve 910 can automatically control the replenishment of water to the ambient temperature water storage chamber 210.

[0095] Furthermore, the inlet solenoid valve 910 is located in the flow path between the first filter element 810 and the second filter element 820. Since the first filter element 810 is made of PP cotton and the second filter element 820 is made of activated carbon, its downstream location protects the inlet solenoid valve 910 from being affected by dirt in the water, ensuring its normal operation and service life. At the same time, its upstream location prevents activated carbon leakage from the second filter element 820 during the filtration process from damaging the inlet solenoid valve 910.

[0096] In one embodiment, referring to Figure 4, the water system also includes a pressure reducing valve 920, which is disposed in the inlet pipe 15 and located upstream of the filter module 800. Since the inlet water source is municipal water, the pressure reducing valve 920 can regulate the inlet water pressure of the water system.

[0097] In one embodiment, referring to Figure 4, the water system further includes a leak protector 930, which is disposed in the inlet pipe 15 and located upstream of the filter module 800. The leak protector 930 is used to prevent water leakage from the water system, thereby affecting the use of the drinking water equipment.

[0098] This application proposes a multifunctional drinking water device 10, which aims to provide both drinking outlets for humans and drinking outlets for pets.

[0099] Please refer to Figures 5 to 8. In one embodiment of this application, the multifunctional drinking water device 10 includes a housing 100. A hot water nozzle 61 and a cold water nozzle 62 are installed on the outside of the housing 100. The housing 100 is also provided with a pet water outlet 120a. The hot water nozzle 61 and the cold water nozzle 62 are located above the pet water outlet 120a. A water basin placement position is located below the pet water outlet 120a.

[0100] The outer side of the housing 100 is equipped with a hot water nozzle 61 and a cold water nozzle 62. The hot water nozzle 61 is used to dispense hot water, and the cold water nozzle 62 is used to dispense cold water. The water dispensed from both the hot water nozzle 61 and the cold water nozzle 62 is for human drinking. In order to facilitate pet drinking, a water bowl placement position is provided on the lower side of the pet water outlet 120a for placing the pet water bowl 400 to collect the water flowing out of the pet water outlet 120a.

[0101] In addition, the multifunctional drinking water device 10 also includes a heating module 300 and a cooling module 200. A support frame 51 is installed inside the housing. The cooling module 200 is installed on the upper side of the support frame 51, and the heating module 300 is installed on the lower side of the support frame 51.

[0102] Specifically, the housing 100 is the housing of the water drinking device. The housing 100 has a front shell, a back plate, a top cover, a base, and two opposing side plates. These parts are interconnected to complete the installation of the housing, primarily through screw connections. The housing 100 forms a relatively sealed mounting cavity, allowing other components of the multi-functional water drinking device 10 to be installed inside, protecting them from external interference. To facilitate the installation of the refrigeration module 200, a support frame 51 is provided inside the refrigeration module 200. The refrigeration module 200 is mounted on the upper side of the support frame 51. The support frame 51 is fixed to the housing, which can be done by screwing or welding. The refrigeration module 200 and the support frame 51 are generally fixed by screwing.

[0103] Understandably, the main function of the cooling module 200 is to cool and store water. Through the combined action of the insulation layer and the temperature control system, the cooling module 200 can maintain the water temperature within a suitable range, ensuring that users can drink cold water at any time, and that the drinking water is both refreshing and comfortable. The main function of the heating module 300 is to store and heat water. Through the coordinated action of the heating plate and the temperature control system, the water in the heating module 300 is heated to the set temperature, thereby providing users with a comfortable and convenient hot water service. The heating module 300 can be directly mounted on the housing, mounted on the support frame 51, or fixed to other supports; no specific limitation is made here.

[0104] It should be noted that, considering the multifunctional water dispenser 10 proposed in this application is a floor-standing water dispenser, the multifunctional water dispenser 10 has a vertical direction. A bisecting line is drawn along the height direction of the housing 100; the portion above the bisecting line is the upper part of the housing 100, and the portion below the bisecting line is the lower part of the housing 100. A cold water nozzle 62 and a hot water nozzle 61 are provided in the upper part, with the cold water nozzle 62 connected to the cooling module 200 and the hot water nozzle 61 connected to the heating module 300, which is basically the same as a conventional water dispenser. In this embodiment, a pet water outlet 120a is also provided in the lower part of the housing 100. The water from the pet water outlet 120a is for pets to drink from. Thus, the multifunctional water dispenser 10 can provide water for both humans and pets.

[0105] The technical solution of this application adopts a design where a cold water nozzle 62 and a hot water nozzle 61 are provided in the housing 100 of the multifunctional drinking water device 10, providing drinking water for humans; a pet water outlet 120a is also provided in the housing 100, providing drinking water for pets. This allows the multifunctional drinking water device 10 to provide drinking water for both humans and pets, integrating a human water dispenser and a pet water dispenser into one unit, thus reducing the space occupied by drinking water devices in the house.

[0106] In the above embodiments, a pet water bowl 400 for holding water may be provided below the pet water outlet 120a, or it may not be provided, allowing the user to place a personalized pet water bowl 400. In this embodiment, please continue to refer to Figures 5 to 8. The multifunctional drinking device 10 also includes a pet water bowl 400, which is installed on the housing 100 and located below the pet water outlet 120a. In this embodiment, the pet water bowl 400 is generally designed as a circular bowl to facilitate drinking for the pet.

[0107] Specifically, the pet water bowl 400 is used to collect the water flowing out of the pet water outlet 120a for the pet to drink. It should be noted that the pet water bowl 400 and the front shell of the housing 100 can be integrated, or the pet water bowl 400 can be installed on the front shell of the housing 100. No specific limitation is made here.

[0108] In one embodiment, referring to FIG8, the pet water bowl 400 is detachably mounted to the housing 100.

[0109] Understandably, considering that users may choose a personalized pet water bowl instead of the pet water bowl 400 of this application, the pet water bowl 400 is detachably installed on the housing 100. This also facilitates cleaning of the pet water bowl 400. The detachable connection between the pet water bowl 400 and the housing 100 can be a magnetic connection or a snap-fit ​​connection. Alternatively, in other embodiments, the pet water bowl 400 of this application may not be installed on the housing 100, but may simply be placed below the pet blower faucet.

[0110] Further, please refer to Figure 5. The distance between the pet water outlet 120a and the bottom of the housing 100 is H, where H satisfies 15mm≤H≤30mm.

[0111] Considering that the pet water outlet 120a needs to be sufficiently far from the bottom of the housing 100 to facilitate the placement of the pet water bowl 400, the distance between the pet water outlet 120a and the bottom of the housing 100 should be greater than or equal to 15mm. Secondly, if the pet water outlet 120a is too high above the pet water bowl 400, it may cause water to splash out of the pet water bowl 400. Therefore, the distance between the pet water outlet 120a and the bottom of the housing 100 should not be too large, and the distance between the pet water outlet 120a and the bottom of the housing 100 should be less than or equal to 30mm.

[0112] Please refer to Figure 5. In one embodiment, the distance between the hot water nozzle 61 and the pet water outlet 120a in the height direction of the housing 100 is D1, and D1 satisfies 50mm≤D1≤80mm.

[0113] It should be noted that the hot water nozzle 61 and the cold water nozzle 62 are basically set on the same horizontal line. Therefore, the distance between the hot water nozzle 61 in the height direction of the housing 100 and the pet water outlet 120a is the same as the distance between the first water outlet 111a in the height direction and the pet water outlet 120a. It should also be noted that D1 should not be too small, otherwise the height of the pet water outlet 120a will be too high, and / or the height of the cold water nozzle 62 and the hot water nozzle 61 will be too low, making it inconvenient for people to use and / or for pets to drink. Therefore, D1 is set to be greater than or equal to 50mm. Secondly, D1 should not be too large, otherwise the height of the pet water outlet 120a will be too low, and / or the height of the cold water nozzle 62 and the hot water nozzle 61 will be too high, making it inconvenient for people to use and / or for pets to drink.

[0114] In one embodiment, please refer to Figures 5 and 6. The housing 100 is provided with a pet water outlet pipe 13 that communicates with the pet water outlet 120a. A solenoid valve 641 is provided on the pet water outlet pipe 13. A pet water outlet switch 520 is provided on the upper part of the housing 100. The pet water outlet switch 520 is electrically connected to the solenoid valve 641.

[0115] It should be noted that the housing 100 is equipped with a pet water outlet pipe 13 that connects to the pet water outlet 120a. The other end of this pet water outlet pipe 13 can be connected to a tap water outlet, the cooling module 200, or the filter module 800 within the multi-functional drinking device 10; no specific limitation is made here. To facilitate control of the water flow from the pet water outlet 120a, a solenoid valve 641 is installed on the pet water outlet pipe 13. When the solenoid valve 641 is in operation, the water path within the solenoid valve 641 connects to the pet water outlet 120a to fill the pet water bowl 400 with water. The solenoid valve 641 is controlled by a pet water outlet switch 520 located on the upper part of the housing 100. When the pet water outlet switch 520 is pressed down, the water path inside the solenoid valve 641 connects to the pet water outlet 120a. When the pet water outlet switch 520 is released, the water path inside the solenoid valve 641 immediately disconnects from the pet water outlet 120a, thus preventing water from overflowing from the pet water bowl 400. This is because common domestic pets, such as cats and dogs, possess a certain level of intelligence and will learn to use the pet water outlet switch 520 to dispense water.

[0116] In one embodiment, referring to Figures 6 and 7, the multifunctional drinking water device 10 further includes a filter module 800, which is installed in the housing 100 and located inside the housing 100. The cooling module 200, the heating module 300, and the pet water outlet pipe 13 are all connected to the filter module 800.

[0117] It should be noted that this multifunctional drinking water device 10 includes a filtration module 800, which is installed inside the housing 100. While the filtration module 800 can be directly installed on the housing 100, in this embodiment, a preferred method is to fix a mounting bracket 52 on the housing 100 to secure the filtration module 800. The filtration module 800 includes multi-stage filter elements, including a pre-filter, a reverse osmosis filter, and a post-filter. Raw water first flows through the pre-filter to remove larger particles and flocculent matter, then flows through the reverse osmosis filter to remove most of the salt ions, and finally flows through the post-filter to remove color and odor. In this embodiment, the heating module 300, the cooling module 200, and the pet water outlet pipe 13 are all connected to the water outlet module, thus ensuring the quality of water for both humans and pets.

[0118] In one embodiment, please refer to Figures 6 and 9. The refrigeration module 200 has a room temperature water storage chamber 210, and the top of the room temperature water storage chamber 210 is located above the first water outlet 111a.

[0119] It should be noted that the refrigeration module 200 has a normal temperature water storage chamber 210, which stores cooling water. It should also be noted that the top of the normal temperature water storage chamber 210 is located above the water outlet, so that cold water can flow out from the first water outlet 111a by its own weight. This eliminates the need to install a water pump to draw water from the refrigeration module 200 into the water pump, thus saving installation steps and costs for this multi-functional water dispenser.

[0120] In one embodiment, please continue to refer to Figures 6 and 9. The distance between the top of the ambient temperature water storage cavity 210 and the first water outlet 111a is D, where D satisfies 10cm≤D≤25cm.

[0121] It should be noted that, due to the limited internal space of the water dispenser, the distance between the first water outlet 111a and the top of the room temperature water storage chamber 210 should not be too large, so D should be less than or equal to 25cm. Also, considering that in order to maintain a better water flow rate at the first water outlet 111a, the water in the room temperature water storage chamber 210 should have sufficient gravitational potential energy, the distance between the top of the room temperature water storage chamber 210 and the first water outlet 111a should not be too small, so D should be greater than or equal to 10cm. Within this limit, the water in the room temperature water storage chamber 210 has good gravitational potential energy.

[0122] In one embodiment, please continue to refer to Figures 6 and 9. The filter module 800 is connected to the interior of the refrigeration module 200 through a first water pipe. The refrigeration module 200 is provided with a flow-blocking component 22. A flow-guiding channel 221 is formed in the flow-blocking component 22. The flow-guiding channel 221 is connected to the pet water outlet pipe 13 through a second water pipe 65. A water branch pipe 66 is led out from the connecting pipe 14 and connected to the interior of the heating module 300.

[0123] It should be noted that in this embodiment, the water filtered by the filter module 800 first flows into the cooling module 200. A flow-blocking component 22 is provided inside the cooling module 200 to separate the water path. A water-passing gap is formed between the flow-blocking component 22 and the inner wall of the cooling module 200, allowing the water to be cooled to flow through the water-passing gap to the lower side of the cooling module 200. A flow-guiding channel 221 is formed on the flow-blocking component 22, through which water flows from the second water-passing pipe 65 to the pet water outlet pipe 13. In addition, the water inlet of the heating module 300 is achieved by leading a water-passing branch pipe 66 out of the second water-passing pipe. Through the above embodiment, only one water path needs to be led out from the filter module 800, and the water flowing out of the filter module 800 only needs to be pressurized by a water pump to the cooling module 200, reducing the need for a water pump.

[0124] In one embodiment, please refer to Figure 6, a one-way valve 661 is installed on the water branch pipe 66 to prevent hot water in the heating module 300 from flowing back.

[0125] It should be noted that, considering the high temperature of the water in the heating module 300, if the water in the heating module 300 flows back into the water-passing branch pipe 66 and further flows from the second water inlet pipe to the pet outlet 120a, it may cause the pet to be scalded. Therefore, a one-way valve 661 is installed on the water-passing branch pipe 66 to ensure that the water can only flow into the heating module 300 from the water-passing branch pipe 66 and cannot flow out of the heating module 300 into the water-passing branch pipe 66.

[0126] In one embodiment, referring to FIG7, the support frame 51 extends toward the heating module 300 to form a stiffener 511, the stiffener 511 being connected to the heating module 300.

[0127] It should be noted that the support frame 51 extends toward the heating module 300 to form a rib 511, and the heating module 300 is installed on the rib 511 to fix the heating module 300. The rib 511 can be straight or L-shaped. There can be one rib 511. In this embodiment, in order to make the fixing of the heating module 300 more stable, two ribs 511 are provided. Of course, there can also be three or more ribs 511.

[0128] In one embodiment, referring to FIG6, the heating module 300 is located between the cooling module 200 and the filter module 800, and the heating module 300 is closer to the hot water tap 61 than the filter module 800.

[0129] It should be noted that, considering that after the heating module 300 heats the water inside, during the process of transmitting it to the hot water tap 61, due to the large temperature difference between the water and the outside environment, heat exchange will occur rapidly with the external environment. If the pipeline is too long, this will cause serious energy loss of the hot water. In this embodiment, the heating module 300 is placed between the cooling module 200 and the filter module 800. The heating module 300 is closer to the hot water tap 61 than the filter module 800, so that the distance between the water flowing out of the heating module 300 and the hot water tap 61 is shorter, which can reduce the energy loss of the hot water flowing out of the heating module 300.

[0130] In one embodiment, referring to FIG6, the multifunctional drinking water device 10 further includes a compressor 8, which is installed at the bottom inside the housing 100.

[0131] It should be noted that the multifunctional water dispenser 10 also includes a compressor 8. Considering that an evaporator is located on the outer periphery of the refrigeration module 200, the compressor 8 draws refrigerant vapor from the evaporator to maintain a certain evaporation pressure within the evaporator. This step ensures that the evaporator can operate continuously and stably, while maintaining a certain evaporation temperature, providing the necessary conditions for the refrigeration process. Considering the relatively large mass of the compressor 8, it is therefore installed at the bottom inside the housing 100.

[0132] This application proposes a water system for use in a multifunctional drinking water device, which is a water purifier, direct drinking water machine, or water dispenser. The water system can provide water for users and pets to drink, thereby enriching the functions of the multifunctional drinking water device.

[0133] Please refer to Figure 10. In one embodiment of this application, the water system 70 includes a first water outlet pipe 11, a second water outlet pipe 12, and a pet water outlet pipe 13. The pet water outlet pipe 13 is used to dispense water for the pet to drink. The water system 70 also includes a cooling module 200 and a heating module 300. The cooling module 200 has a normal temperature water storage chamber 210 and a cold water storage chamber 220. The output side of the normal temperature water storage chamber 210 is connected to the pet water outlet pipe 13, and the output side of the cold water storage chamber 220 is connected to the first water outlet pipe 11. The input port of the heating module 300 is connected to the normal temperature water storage chamber 210, and the output port of the heating module 300 is connected to the second water outlet pipe 12.

[0134] Specifically, the refrigeration module 200 includes a room temperature water storage chamber 210 and a cold water storage chamber 220. The room temperature water storage chamber 210 is connected to a water source and is used to store room temperature water, i.e., water that has not undergone refrigeration or heating treatment. The water source can be municipal tap water or purified water stored in a sealed container. If the water flowing into the room temperature water storage chamber 210 is municipal tap water, a filter module 800 can be installed upstream of the room temperature water storage chamber 210 to filter the water before it flows into the room temperature water storage chamber 210, improving the taste and health of the drinking water. Details of the filter module 800's configuration will be provided later and will not be elaborated upon here. The output side of the room temperature water storage chamber 210 is connected to the inlet side of the pet water outlet pipe 13. This means that the room temperature water flowing into the room temperature water storage chamber 210 can be directly discharged through the pet water outlet pipe 13 for the pet's use, unaffected by the user's drinking water (cold or hot water).

[0135] The cold water storage chamber 220 is also connected to a water source. The water in the cold water storage chamber 220 is cooled by the heat exchange component 700. The output side of the cold water storage chamber 220 is connected to the first water outlet pipe 11. When a user needs cold water, the water in the cold water storage chamber 220 can flow out through the first water outlet pipe 11 for the user's use. The heat exchange component 700 can be integrated into the refrigeration module 200, or it can be set up separately to cool the water in the cold water storage chamber 220. There is no specific limitation on this.

[0136] Regarding the connection method between the cold water storage chamber 220 and the water source, it can be directly connected to the water source through a water interface, or indirectly connected through the ambient temperature storage chamber 210. When the cold water storage chamber 220 is indirectly connected to the water source through the ambient temperature storage chamber 210, the method can be to set a flow divider in the refrigeration module 200. Through the function of the flow divider, the interior of the refrigeration module 200 is divided into the isolated ambient temperature storage chamber 210 and the cold water storage chamber 220. The ambient temperature storage chamber 210 is directly connected to the water source. The flow divider is provided with a connecting flow path, and the cold water storage chamber 220 is connected to the ambient temperature storage chamber 210 through the connecting flow path, thereby achieving connection with the water source. In this embodiment, in order to reduce the number of pipes upstream of the refrigeration module 200 and the number of water interfaces of the refrigeration module 200 itself, the cold water storage chamber 220 is connected to the water source indirectly.

[0137] Please refer to Figure 10. The input port of the heating module 300 is connected to the ambient temperature water storage chamber 210, and the outlet port is connected to the second water outlet pipe 12. The heating module 300 typically has a heating state and a non-heating state. When the heating module 300 is in the heating state, the ambient temperature water in the ambient temperature water storage chamber 210 can flow into the heating module 300 through the input port for heating, and then flow out through the second water outlet pipe 12 for drinking. When the heating module 300 is in the non-heating state, the ambient temperature water in the ambient temperature water storage chamber 210 flows through the heating module 300 and out through the second water outlet pipe 12 for drinking; the water flowing out at this time is ambient temperature water. In this way, the user's needs for both hot water and ambient temperature water can be met.

[0138] It should be noted that the terms "inlet" and "inlet side" mentioned above and below refer to the side where water flows in, and similarly, "outlet" and "outlet side" refer to the side where water flows out.

[0139] The water flowing into the ambient temperature water storage chamber 210 is connected to the water source via an inlet pipe 15 in the water system 70. Since the cold water storage chamber 220 is indirectly connected to the water source via the ambient temperature water storage chamber 210, only one inlet pipe 15 is needed in this embodiment, simplifying the water system 70. The pet water outlet pipe 13 connects to the ambient temperature water storage chamber 210, which simplifies the water system 70 and shortens the length of the pet water outlet pipe 13. This ensures that when the water system 70 is used in a multi-functional drinking device, the piping layout within the device can be simplified. Since the pet water outlet pipe 13 is directly connected to the ambient temperature water storage chamber 210, it is not affected by cold or hot water when the pet drinks, ensuring that the pet can drink water at a suitable temperature.

[0140] The water system 70 of this application features a first water outlet pipe 11, a second water outlet pipe 12, and a pet water outlet pipe 13. The first water outlet pipe 11 connects to the cold water storage chamber 220 of the cooling module 200, dispensing cold water for user drinking. The second water outlet pipe 12 connects to the heating module 300, dispensing room temperature water or heated water for user drinking. The pet water outlet pipe 13 connects to the room temperature storage chamber 210 of the cooling module 200, allowing room temperature water to flow directly for pet drinking without being affected by cold or hot water. This achieves the simultaneous dispensing of drinking water and pet water for both users and pets, enriching the water dispensing functions of the water system 70. Furthermore, the piping layout of the water system 70 is simple and easy to manufacture. Simultaneously, it enables multi-functional drinking devices using the water system 70 to provide drinking water for both users and pets, integrating multiple functions for user convenience.

[0141] Please refer to Figure 10. In one embodiment, the water system 70 further includes a connecting pipe 14. The refrigeration module 200 is provided with a normal temperature output port 230 that communicates with the normal temperature water storage chamber 210. The input port and the normal temperature output port 230 of the heating module 300 are connected through the connecting pipe 14.

[0142] Specifically, a connecting pipe 14 can be installed between the cooling module 200 and the heating module 300 to allow water in the ambient temperature water storage chamber 210 to flow into the heating module 300 through the connecting pipe 14 and then flow out through the second water outlet pipe 12 for user use. The cooling module 200 has an ambient temperature output port 230 that communicates with the ambient temperature water storage chamber 210. One end of the connecting pipe 14 is connected to this ambient temperature output port 230, and the other end is connected to the output port of the heating module 300.

[0143] Furthermore, one end of the pet water outlet pipe 13 is connected to the connecting pipe 14 to communicate with the ambient temperature water storage chamber 210, and the other end is used to dispense water for the pet to drink. Specifically, to reduce the number of water interface ports of the cooling module 200, one end of the pet water outlet pipe 13 is directly connected to the connecting pipe 14, thereby achieving communication with the ambient temperature water storage chamber 210, so that water in the ambient temperature water storage chamber 210 can flow out through the pet water outlet pipe 13 for the pet to drink.

[0144] Referring to Figure 10, in one embodiment, the water system 70 includes a water outlet valve 510, which is located in the pet water outlet pipe 13 and used to control the opening and closing of the pet water outlet pipe 13. Specifically, the user can control the opening and closing of the water flow in the pet water outlet pipe 13 by controlling the water outlet valve 510, thereby dispensing water when needed. Furthermore, when the water outlet valve 510 is in the open state, water flows from the pet water outlet pipe 13 into an external pet water bowl for the pet to drink. The water outlet valve 510 can be a manual valve, allowing water to be added directly to the pet water bowl through manual control; alternatively, the water outlet valve 510 can be a solenoid valve, controlled by a water outlet switch electrically connected to it, thereby adding water to the pet water bowl.

[0145] Referring to Figures 10 and 11, in one embodiment, the water system 70 further includes a one-way valve 600. The one-way valve 600 is disposed in the connecting pipe 14 and located between the inlet end of the pet water outlet pipe 13 and the input port of the heating module 300. Specifically, during the heating process of the heating module 300, due to thermal expansion and contraction, some hot water will flow back into the connecting pipe 14, affecting the water temperature. This will cause the water temperature at the outlet of the pet water outlet pipe 13 connected to the connecting pipe 14 to be too high. Therefore, a one-way valve 600 is installed between the inlet end of the pet water outlet pipe 13 and the input port of the heating module 300 to prevent the backflow of hot water generated by the heating module 300 during the heating process, thus meeting the requirement of stable pet drinking water temperature.

[0146] Referring to Figures 10 and 11, in one embodiment, the refrigeration module 200 further includes a room temperature input port 140 and a cold water output port 150. The room temperature input port 140 is connected to both the room temperature water storage chamber 210 and the cold water storage chamber 220, and is used to connect to a water source. The cold water output port 150 is connected to the cold water storage chamber 220 and is also connected to the first water outlet pipe 11. Specifically, the refrigeration module 200 also includes a room temperature input port 140 for connecting to the water inlet pipe 15 and a cold water output port 150 for connecting to the first water outlet pipe 11.

[0147] Please refer to Figures 10 and 11. In one embodiment, the water system 70 further includes a cold water switch valve 410 and a hot water switch valve 420. The cold water switch valve 410 is located on the outlet side of the first outlet pipe 11 and is used to control the opening and closing of the first outlet pipe 11. The second outlet 111b is located on the outlet side of the second outlet pipe 12 and is used to control the opening and closing of the second outlet pipe 12.

[0148] Specifically, the cold water switch valve 410 and the hot water switch valve 420 can be configured as manual mechanical valves, allowing water to be supplied directly to users through manual control. Alternatively, the cold water switch valve 410 and the hot water switch valve 420 can also be solenoid valves, which are controlled by a water outlet switch electrically connected to them, thereby supplying water to users.

[0149] Referring to Figures 10 and 11, in one embodiment, the water system 70 further includes an exhaust branch 16, which connects the heating module 300 and the ambient temperature water storage chamber 210. Specifically, the exhaust branch 16 is used to exhaust the hot steam generated by the heating module 300 during operation into the ambient temperature water storage chamber 210, so as to ensure that the gas does not flow out from the second water outlet pipe 12 and to ensure the stability of the hot water output.

[0150] Referring to Figures 10 and 11, in one embodiment, the water system 70 further includes a drainage branch 17, which is connected to the heating module 300. When the user does not use the multi-functional drinking water device using the water system 70 for a long time, the water in the entire water system 70 can be drained through the drainage branch 17, that is, the water in the cooling module 200 and the heating module 300 can be drained.

[0151] Referring to Figures 10 and 11, in one embodiment, the water system 70 further includes a heat exchange component 700, which is connected to the refrigeration module 200 and used to cool the water in the cold water storage chamber 220 of the refrigeration module 200. Specifically, in this embodiment, the refrigeration module 200 cools the water in its cold water storage chamber 220 through the heat exchange component 700. The heat exchange component 700 includes an evaporator 710, a condenser 720, a compressor 730, and a capillary tube 740 (or an electronic expansion valve 740). The evaporator 710 can be fitted onto the outer wall of the refrigeration module 200 and is positioned corresponding to the location of the cold water storage chamber 220 to cool the water in the cold water storage chamber 220.

[0152] Referring to Figures 10 and 11, in one embodiment, the water system 70 further includes a filter module 800, which is disposed in the inlet pipe 15. Specifically, when the inlet pipe 15 is directly connected to municipal water, the filter module 800 needs to be installed upstream of the cooling module 200 to filter the municipal water, which then flows into the ambient temperature water storage chamber 210 and the cooling water storage chamber of the cooling module 200, and flows out through the first outlet pipe 11, the second outlet pipe 12 and the pet outlet pipe 13 respectively for drinking by the user and the pet.

[0153] Furthermore, the filter module 800 includes a first filter element 810 and a second filter element 820. The first filter element 810 is made of PP, and the second filter element 820 is made of activated carbon. Specifically, the main material of the first filter element 810 is polypropylene (PP), which has high filtration accuracy, small size, and large filtration area. PP cotton filter elements can effectively filter impurities in water, such as sediment, rust, and suspended solids, making the water clearer and more transparent; they can also remove odors from the water, such as chlorine and foul smells, improving the taste and quality of the water; and they have a certain antibacterial ability, which can effectively prevent bacteria from growing inside the filter element and ensure the hygiene and safety of the water; at the same time, as a pre-filter element of drinking water (water purification) equipment, it can effectively protect subsequent filter elements and equipment, preventing impurities and contaminants from entering subsequent filter elements and equipment, thereby extending the service life of the equipment; and PP cotton filter elements have a long service life and low maintenance costs, which helps to reduce the operating and maintenance costs of the equipment. The second filter element 820 is made of activated carbon. Due to its porous structure, activated carbon has an extremely large specific surface area, with each gram of activated carbon having a surface area of ​​500–1500 m². 2 It can efficiently adsorb organic matter, residual chlorine, odors, colors, and other radioactive substances in water. Furthermore, the activated carbon filter effectively removes harmful substances and odors such as formaldehyde, benzene, and ammonia, significantly improving water quality. The dual-filter setup further enhances water filtration, thereby improving the health and safety of water for users and pets.

[0154] Please refer to Figures 10 and 11. In one embodiment, the water system 70 is further provided with an inlet solenoid valve 910, which is located in the inlet pipe 15. That is, the inlet solenoid valve 910 is located upstream of the refrigeration module 200. The inlet solenoid valve 910 can be used to control the flow of water to the ambient temperature water storage chamber 210 of the refrigeration module 200. When the water volume in the ambient temperature water storage chamber 210 is insufficient, the inlet solenoid valve 910 can automatically control the replenishment of water to the ambient temperature water storage chamber 210.

[0155] Furthermore, the inlet solenoid valve 910 is located in the flow path between the first filter element 810 and the second filter element 820. Since the first filter element 810 is made of PP cotton and the second filter element 820 is made of activated carbon, its downstream location protects the inlet solenoid valve 910 from being affected by dirt in the water, ensuring its normal operation and service life. At the same time, its upstream location prevents activated carbon leakage from the second filter element 820 during the filtration process from damaging the inlet solenoid valve 910.

[0156] Referring to Figures 10 and 11, in one embodiment, the water system 70 further includes a pressure reducing valve 920, which is disposed in the inlet pipe 15 and located upstream of the filter module 800. Since the inlet water source is municipal water, the pressure reducing valve 920 can regulate the inlet water pressure of the water system 70.

[0157] Referring to Figures 10 and 11, in one embodiment, the water system 70 further includes a leak protector 930, which is disposed in the inlet pipe 15 and located upstream of the filter module 800. The leak protector 930 is used to prevent water leakage from the water system 70, thereby affecting the use of the multifunctional drinking water equipment.

[0158] This application also proposes a multifunctional drinking water device, which includes the aforementioned water system 70. The specific structure of the water system 70 is as described in the above embodiments. Since this multifunctional drinking water device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
