Description

Technical Field

[0001] This utility model relates to the technical field of water dispensers, specifically a multifunctional water dispenser. Background Technology

[0002] Chinese patent ZL202021794218.6 discloses a water dispenser with instant heating or cooling based on the Internet of Things (IoT). This device uses a semiconductor cooling chip located outside the cold water chamber for cooling, but its liquid flow path lacks control over the flow rate and heat exchange process. The liquid flows quickly after directly entering the cold water chamber, resulting in insufficient effective heat exchange time with the cooling chip and limited cooling efficiency. Therefore, to ensure the cold water temperature, the liquid needs to remain stationary in the chamber for a sufficient time, failing to meet the requirement of instant low-temperature cold water output.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The present invention aims to provide a multifunctional drinking water device, wherein the flow-slowing plate in the cooling water tank assembly can effectively slow down the flow rate of the liquid, so that the liquid can fully contact the cooling fin assembly during the flow process, increase the effective heat exchange time between the liquid and the cooling fin assembly, improve the cooling efficiency, and meet the need for immediate output of low-temperature cold water without the liquid remaining in the cavity, thereby overcoming the shortcomings of the prior art.

[0005] A multifunctional drinking water device designed for this purpose includes a body, on which a water outlet assembly, a cooling water tank assembly, an instant heater, a first water pump, a second water pump, and a water storage tank are provided.

[0006] When the water outlet assembly outputs hot water, the liquid enters the instant heater for heating via the first water pump; when the water outlet assembly outputs cold water, the liquid enters the cooling water tank assembly for cooling via the second water pump. By activating the corresponding water pump, hot or cold water can be output at the water outlet assembly.

[0007] The cooling water tank assembly is equipped with a flow buffer and a cooling fin assembly. The water inlet of the cooling water tank assembly, the flow buffer, and the cooling fin assembly are arranged at intervals. The liquid entering the cooling water tank assembly slows down its flow rate along the flow buffer and flows to the cooling fin assembly for cooling.

[0008] The cooling water tank assembly includes a refrigeration unit, a tank body, and an inner liner, with the inner liner installed inside the tank body;

[0009] The cooling fin assembly is fixed to the cabinet. Part of the cooling fin assembly is located inside the inner liner, and the other part is located outside the inner liner and abuts against the cooling end of the refrigeration assembly.

[0010] The flow damper is installed inside the inner liner.

[0011] An insulation layer is provided between the box body and the inner liner;

[0012] A drain outlet is provided at the bottom of the inner liner.

[0013] The refrigeration assembly includes a cooling fan, a heat dissipation fin assembly, and a semiconductor cooling chip. The semiconductor cooling chip abuts against the heat-conducting fin assembly located outside the inner liner. The heat dissipation fin assembly is located between the cooling fan and the semiconductor cooling chip. The heat dissipation fin assembly is fixedly connected to the housing and the support of the cooling fan, respectively.

[0014] The water storage tank is provided with a cavity for installing the filter module.

[0015] The water storage tank is detachably installed on the machine body. The water outlet end of the water storage tank is equipped with a flexible valve core assembly. After the water storage tank is detached, the valve core assembly seals the water outlet end of the water storage tank under the elastic action.

[0016] The machine body is also equipped with a shell, and a connecting seat is provided at one end of the shell. A top column is provided on the connecting seat. When the water storage tank is assembled with the machine body, the top column pushes open the valve core assembly to open the water outlet of the water storage tank.

[0017] The valve core assembly includes a valve body, a sealing plate, and a spring. The first end of the valve body is inserted into the water storage tank and connected to the sealing plate. The second end of the valve body extends out of the bottom of the water storage tank, and the spring is located between the second end of the valve body and the bottom of the water storage tank.

[0018] The bottom of the water tank is provided with an extension, and the connecting seat is provided with an installation groove. When the water tank is assembled with the machine body, the extension is inserted into the installation groove and the two are sealed together by a sealing component.

[0019] The housing is provided with a positioning part and a connecting rib, and the water tank is provided with a groove and a slot. When the water tank is assembled with the body, the positioning part is installed on the groove and the connecting rib is inserted into the slot.

[0020] A partition area for installing the housing is provided between the water outlet assembly and the water storage tank. A bracket is provided inside the housing and is suspended and fixed on the housing. The cooling water tank assembly is located below the bracket. A bottom cover for covering the lower opening of the housing is provided on the housing.

[0021] An instant heater and a first water pump are installed alternately on one side of a bracket. The instant heater is equipped with a thermostat and a temperature sensor for detecting the outlet water temperature. A first circuit board is installed on the other side of the bracket.

[0022] The refrigeration assembly is provided with a second circuit board, which is electrically connected to the cooling fan, the semiconductor cooling chip, the second water pump, and the first circuit board.

[0023] The housing is provided with a touch control display screen and a third circuit board, and the third circuit board is electrically connected to the second circuit board and the touch control display screen respectively.

[0024] The body is also equipped with a front panel, which is fixedly connected to the water outlet assembly and the housing.

[0025] The water outlet assembly includes an upper shell and a lower shell. The upper shell contains a light panel for indicating whether hot or cold water is being output, and a light-transmitting part for observing the light on the light panel. The lower shell contains the water outlet.

[0026] This invention, through structural improvements, enables the water outlet assembly of the drinking water device to output either hot or cold water. The output of hot or cold water can be switched by activating the corresponding pump, providing flexibility. Furthermore, the flow-damping plate within the cooling water tank assembly effectively slows the liquid flow rate, allowing the liquid to fully contact the cooling fins during flow. This increases the effective heat exchange time between the liquid and the cooling fins, improving cooling efficiency. It eliminates the need for the liquid to remain stationary within the chamber, meeting the demand for immediate low-temperature cold water output. Attached Figure Description

[0040] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0041] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0042] See Figures 1-13 A multifunctional drinking water device includes a body, on which a water outlet assembly 1, a cooling water tank assembly 2, an instant heater 3, a first water pump 4, a second water pump 5, and a water storage tank 6 are provided.

[0043] When the water outlet assembly 1 outputs hot water, the liquid enters the instant heater 3 for heating via the first water pump 4; when the water outlet assembly 1 outputs cold water, the liquid enters the cooling water tank assembly 2 for cooling via the second water pump 5. By starting the corresponding water pump, hot or cold water can be output on the water outlet assembly 1.

[0044] The cooling water tank assembly 2 is provided with a flow-slowing plate 205 for slowing down the liquid flow rate and a heat-conducting fin assembly 203 for heat exchange. The water inlet end of the cooling water tank assembly 2, the flow-slowing plate 205 and the heat-conducting fin assembly 203 are arranged vertically at intervals. The liquid entering the cooling water tank assembly 2 slows down its flow rate along the flow-slowing plate 205 and flows to the heat-conducting fin assembly 203 for cooling.

[0045] The water outlet of the water storage tank 6 is connected to the input of the first water pump 4 and the input of the second water pump 5 respectively; the output of the first water pump 4 is connected to the inlet of the instant heater 3, and the output of the second water pump 5 is connected to the inlet 200 of the cooling water tank assembly 2; the inlet of the water outlet assembly 1 is connected to the outlet of the cooling water tank assembly 2 and the outlet of the instant heater 3 respectively.

[0046] When the first water pump 4 starts, the liquid in the water storage tank 6 enters the instant heater 3 through the first water pump 4 and is heated so that the water outlet assembly 1 outputs hot water.

[0047] When the second water pump 5 starts, the liquid in the water storage tank 6 enters the cooling water tank assembly 2 through the second water pump 5 for cooling, so that the water outlet assembly 1 outputs cold water.

[0048] By incorporating a water outlet assembly 1, a cooling water tank assembly 2, an instantaneous heater 3, a first water pump 4, a second water pump 5, and a water storage tank 6 on the machine body, the first water pump 4 controls the liquid to enter the instantaneous heater 3 to output hot water, while the second water pump 5 controls the liquid to enter the cooling water tank assembly 2 to output cold water, achieving precise switching between hot and cold water output and providing flexible operation. The flow-damping plate 205 inside the cooling water tank assembly 2 effectively slows down the liquid flow rate, allowing the liquid to fully contact the cooling fin assembly 203 during flow, increasing the effective heat exchange time between the liquid and the cooling fin assembly 203, improving cooling efficiency, and meeting the need for immediate output of low-temperature cold water without the liquid needing to remain stagnant in the cavity.

[0049] Specifically: The chilled water tank assembly 2 is provided with two spaced-apart first flow buffers, and a second flow buffer is provided below the two first flow buffers. The second flow buffer is located below the gap between the two first flow buffers. One of the first flow buffers is located below the water inlet 200 of the chilled water tank assembly 2. The liquid entering through the water inlet 200 drips onto the first flow buffer and then flows from the gap between the two first flow buffers to the second flow buffer. The top of the chilled water tank assembly 2 is provided with a water outlet 211. A water pipe is inserted into the chilled water tank assembly 2 through the water outlet 211. There is a water outlet gap between the water pipe and the bottom wall of the chilled water tank assembly 2. When cold water needs to be output, the second water pump 5 is started. When the liquid level in the chilled water tank assembly 2 exceeds the water outlet gap, the liquid in the chilled water tank assembly 2 enters the water pipe from bottom to top and flows to the water outlet assembly 1.

[0050] The cooling water tank assembly 2 includes a cooling assembly 201, a tank body 202 and an inner liner 204, with the inner liner 204 installed inside the tank body 202;

[0051] The first end of the cooling fin assembly 203 is fixed on the housing 202, and its second end is located on the inner liner 204. The cooling end of the refrigeration assembly 201 abuts against the first end of the cooling fin assembly 203.

[0052] The flow-damping plate 205 is installed inside the inner tank 204, the inlet 200 and the outlet 211 are installed on the top of the inner tank 204, and one side of the inner tank 204 is open to insert the cooling fin assembly 203.

[0053] The first end of the cooling fin assembly 203 is fixed to the housing 202, and the second end is located on the inner liner 204. The cooling end of the refrigeration assembly 201 abuts against the first end of the cooling fin assembly 203, allowing the cooling energy generated by the refrigeration assembly 201 to be efficiently transferred to the liquid in the inner liner 204 through the cooling fin assembly 203. The cooling energy transfer path is short and stable. The flow damper 205 is installed inside the inner liner 204 and can directly act on the liquid in the inner liner 204, slowing down the flow rate more specifically and ensuring that the liquid in the inner liner 204 has sufficient contact with the cooling fin assembly 203 for heat exchange, thus ensuring stable cooling effect.

[0054] A heat insulation layer 206 is provided between the box body 202 and the inner liner 204. The heat insulation layer 206 provided between the box body 202 and the inner liner 204 can effectively reduce the loss of cold energy of the liquid in the inner liner 204 to the outside after cooling.

[0055] The lower part of the inner liner 204 is provided with a drain port 210, which can conveniently discharge impurities, sediments and other substances generated in the inner liner 204 during long-term use. The drain port 210 is connected to a drain pipe, and a drain solenoid valve is provided on the drain pipe. The outlet end of the drain pipe extends to the water receiving tray. When the drain solenoid valve is opened, the liquid in the inner liner 204 flows along the drain pipe to the water receiving tray.

[0056] The housing 202 is provided with a fixing frame 21 for fixing the semiconductor cooling chip 209. The fixing frame 21 is fixed to the housing 202 by screws.

[0057] The refrigeration assembly 201 includes a cooling fan 207, a heat dissipation fin assembly 208, and a semiconductor cooling chip 209. The semiconductor cooling chip 209 acts on the first end of the cooling fin assembly 203. The heat dissipation fin assembly 208 is located between the cooling fan 207 and the semiconductor cooling chip 209. The heat dissipation fin assembly 208 is fixedly connected to the housing 202 and the bracket of the cooling fan 207, respectively.

[0058] In the refrigeration assembly 201, the thermoelectric cooler 209 acts directly on the first end of the cooling fin assembly 203, allowing for direct transfer of cooling energy to the fin assembly 203 with high efficiency. The heat dissipation fin assembly 208, located between the cooling fan 207 and the thermoelectric cooler 209, increases the heat dissipation area on the heat dissipation side of the thermoelectric cooler 209. Combined with the accelerated airflow from the cooling fan 207, it quickly removes the heat generated by the thermoelectric cooler 209 during operation, preventing heat buildup that could reduce its cooling efficiency. The heat dissipation fin assembly 208 is fixedly connected to the housing 202 and the bracket of the cooling fan 207, ensuring a secure installation of the heat dissipation structure.

[0059] The water storage tank 6 is provided with a recess 604 for installing a filter module. The filter module is an activated carbon adsorption module. The recess 604 in the water storage tank 6 provides a dedicated installation position for the filter module, facilitating precise installation and positioning. The filter module can filter the liquid in the water storage tank 6, and the structure of the recess 604 makes the installation, disassembly, maintenance, and replacement of the filter module more convenient.

[0060] The water storage tank 6 is detachably installed on the machine body. The water outlet end of the water storage tank 6 is provided with a flexible valve core assembly 8. After the water storage tank 6 is detached, the valve core assembly seals the water outlet end of the water storage tank 6 under the elastic action.

[0061] The machine body is also provided with a housing 11, a connecting seat 9 is provided at one end of the housing 11, and a top column 901 is provided on the connecting seat 9. When the water storage tank 6 is assembled with the machine body, the top column 901 pushes open the valve core assembly 8 to open the water outlet of the water storage tank 6.

[0062] The valve core assembly 8 includes a valve body 801, a sealing plate 802, and a spring 803. The first end of the valve body 801 is inserted into the water storage tank 6 and connected to the sealing plate 802. The second end of the valve body 801 extends out of the bottom of the water storage tank 6, and the spring 803 is located between the second end of the valve body 801 and the bottom of the water storage tank 6.

[0063] The water storage tank 6 is detachably installed on the machine body, allowing users to easily disassemble it for regular water addition and cleaning, ensuring convenient and hygienic maintenance. The elastic movable valve core assembly 8 at the outlet of the water storage tank 6, after the water storage tank 6 is disassembled, is pushed by the elastic force of the spring 803 to the valve body 801, causing the sealing plate 802 to tightly seal the outlet of the water storage tank 6, effectively preventing leakage of residual liquid inside the water storage tank 6 and avoiding environmental pollution. The connecting seat 9 on the machine body is equipped with a top post 901. When the water storage tank 6 is assembled, the top post 901 automatically opens the valve core assembly 8, allowing the outlet to be opened without manual operation, making it convenient to use.

[0064] The water storage tank 6 has an extension 601 at the bottom and a mounting groove 902 on the connecting seat 9. When the water storage tank 6 is assembled with the machine body, the extension 601 is inserted into the mounting groove 902 and the two are sealed together by the sealing element 10.

[0065] The housing 11 is provided with a positioning part 1101 and a connecting rib 1102, and the water tank 6 is provided with a groove 602 and a slot 603. When the water tank 6 is assembled with the body, the positioning part 1101 is installed on the groove 602 and the connecting rib 1102 is inserted into the slot 603.

[0066] One end of the mounting slot 902 is provided with a water outlet connector 22, which is connected to the input end of the first water pump 4 and the input end of the second water pump 5 through corresponding pipes and three-way valves, respectively.

[0067] The extension 601 at the bottom of the water tank 6 is inserted into the mounting groove 902 of the connecting seat 9, and works with the sealing element 10 to achieve a sealing fit between the water tank 6 and the connecting seat 9, enhancing the sealing performance and preventing liquid leakage from the connection. The positioning part 1101 on the housing 11 cooperates with the groove 602 of the water tank 6, and the insertion rib 1102 cooperates with the slot 603 of the water tank 6, which can accurately position the installation of the water tank 6, avoid installation misalignment, and ensure that the top post 901 on the connecting seat 9 can accurately push open the valve core assembly 8. The positioning and insertion structure improves the stability of the water tank 6 after installation and has a foolproof installation effect.

[0068] A partition area for installing the housing 11 is provided between the water outlet assembly 1 and the water storage tank 6. A bracket 12 is provided inside the housing 11. The bracket 12 is suspended and fixed to the housing 11 by screws. At least a space is left below the bracket 12 on the housing 11 for installing the cooling water tank assembly 2, so that the cooling water tank assembly 2 is located below the bracket 12. A bottom cover 17 is provided on the housing 11 for covering the lower opening of the housing 11.

[0069] A screw connection post for inserting screws is provided between the bracket 12 and the housing 11.

[0070] The instant heater 3 and the first water pump 4 are spaced apart and cooperate with each other. At the same time, the instant heater 3 and the first water pump 4 are both fixed on the first side of the bracket 12. The instant heater 3 is equipped with a thermostat 14 and a temperature sensor 15 for detecting the outlet water temperature. The second side of the bracket 12 is equipped with a first circuit board 13, which is electrically connected to the instant heater 3, the first water pump 4, the thermostat 14, and the temperature sensor 15.

[0071] The partition between the water outlet assembly 1 and the water storage tank 6 provides a stable installation space for the housing 11. The bracket 12 inside the housing 11 is suspended and fixed, and the reserved space below it facilitates the reasonable installation of the cooling water tank assembly 2, making the internal layout of the equipment compact and maximizing space utilization. The instantaneous heater 3 and the first water pump 4 are separately fixed on the first side of the bracket 12 to avoid mutual interference during operation and to facilitate heat dissipation. The heat generated by the instantaneous heater 3 is not directly transferred to the first water pump 4, ensuring operational stability. The thermostat 14 on the instantaneous heater 3 prevents the heater from overheating, and the temperature sensor 15 monitors the outlet water temperature in real time to ensure stable hot water temperature. The housing 11 is provided with heat dissipation holes 1103.
