Detailed Implementation

[0037] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] Combination Figures 1 to 12 According to an embodiment of the present invention, a drinking water device 100 includes: an AC input module 10, a first power supply module 20, a second power supply module 30, a DC input module 40, and a second electrical module 50. The AC input module 10 is used to input AC power; the first power supply module 20 is connected to the AC input module 10 and is used to rectify the AC power input by the AC input module 10 to generate a first DC power; the second power supply module 30 is connected to the first power supply module 20 and is used to step down the first DC power output by the first power supply module 20 to generate a second DC power; and the DC input module 40 is used to input a fourth DC power.

[0039] The second electrical module 50 is connected to the second power supply module 30 and the DC input module 40. The second electrical module 50 can be driven by the second DC power output from the second power supply module 30 or the fourth DC power input from the DC input module 40. When the AC input module 10 inputs AC power, the second DC power drives the second electrical module 50; when the AC input module 10 cannot input AC power, the fourth DC power can drive the second electrical module 50 to maintain the normal operation of the second electrical module 50 and ensure that some functions of the drinking water equipment 100 (such as filtration and water dispensing) can still operate normally.

[0040] For example, the drinking water device 100 can filter tap water to produce drinking water, and can also heat or cool drinking water and dispense drinking water. When the AC mains supplies AC power to the AC input module 10, the AC power is sent to the first power supply module 20 for rectification to generate first DC power. The first DC power has a relatively high voltage. A portion of the first DC power can be used to realize the power-intensive functions of the drinking water device 100, such as heating and cooling drinking water, while another portion of the first DC power can be sent to the second power supply module 30 to reduce the voltage of the first DC power to generate second DC power. The second DC power can be sent to the second electrical module 50 to maintain the normal operation of the second electrical module 50.

[0041] The second DC power can be used to achieve the function of moderate power consumption in the drinking water equipment 100, such as filtering tap water and outputting drinking water. The second electrical module 50 may include components for filtering and water output (such as the filter module 51 or water output module 52 described below). The second DC power is supplied to the second electrical module 50 to maintain the normal operation of the drinking water equipment 100 and realize the functions of heating and cooling drinking water, filtering tap water, and outputting drinking water.

[0042] When external environmental conditions such as power outages or natural disasters occur, the mains power cannot supply power to the AC input module 10. At this time, the DC input module 40 can supply a fourth DC power to the second electrical module 50. The second electrical module 50 can be driven by the fourth DC power to maintain its normal operation. The drinking water device 100 cannot perform functions with high power consumption. However, the functions of the second electrical module 50 can still be performed, such as filtering tap water and dispensing drinking water, to maintain the normal operation of some functions of the drinking water device 100. This makes the use scenarios of the drinking water device 100 more diverse. Even in extreme situations such as power outages or natural disasters, users can obtain filtered drinking water from the drinking water device 100, which helps to improve the user's water access experience.

[0043] According to the embodiments of the present invention, when the AC power input module 10 fails to supply power, the second electrical module 50 is driven by the fourth DC power input from the DC power input module 40, which helps to maintain the normal operation of the second electrical module 50 and diversify the usage scenarios of the drinking water device 100.

[0044] Optionally, the DC input module 40 can input a fourth DC power by installing a battery. For example, the DC input module 40 may include a battery compartment to input a fourth DC power to the second electrical module 50 via a disposable or rechargeable battery. Alternatively, the DC input module 40 can also input a fourth DC power via a wired connection. For example, the DC input module 40 includes a USB interface, and an external backup battery pack 130 can be connected to the USB interface of the DC input module 40 via a charging cable to input a fourth DC power to the water dispenser 100, thereby maintaining the normal operation of the second electrical module 50. Even in extreme situations such as power outages, the water dispenser 100 can still filter tap water, or users can still easily obtain water from the water dispenser 100, which helps to expand the usage scenarios of the water dispenser 100.

[0045] Optionally, the first power supply module 20 may include an AC-DC circuit module, which is a core component used to convert alternating current (AC) into direct current (DC) required by the device. Its working principle incorporates two technical paths: linear power supply and switching power supply. The former achieves conversion through transformer step-down combined with rectification and filtering, while the latter uses high-frequency switching technology to improve conversion efficiency. This module features safety characteristics such as input isolation and overload protection, and its typical applications cover consumer electronics, industrial automation, and other fields.

[0046] Optionally, the second power supply module 30 may include a PWM controller and a transformer. The PWM controller generates a corresponding PWM signal based on the input voltage and current information. This PWM signal is used to control the switching state of the transformer, thereby regulating the output voltage. By changing the duty cycle of the PWM signal, precise control of the output voltage can be achieved. Using a PWM controller and a transformer allows for rapid response to changes in the input signal, enabling rapid regulation of the output voltage and precise control over a wide range. Simultaneously, the PWM controller combined with the transformer to achieve voltage reduction effectively reduces energy loss.

[0047] Combination Figures 1 to 4 In some embodiments, the drinking water device 100 includes a switch module 60, which is connected to the second power supply module 30, the DC input module 40, and the second electrical module 50. The switch module 60 is configured to control the second DC power output from the second power supply module 30 and the fourth DC power input from the DC input module 40 to be selectively supplied to the second electrical module 50. That is, when the AC mains power supplies the AC input module 10, the switch module 60 controls the second DC power to be supplied to the second electrical module 50; when a power outage occurs, the switch module 60 controls the fourth DC power to be supplied to the second electrical module 50 to maintain the normal operation of the second electrical module 50.

[0048] For example, the AC input module 10 may include a power cord that can be plugged into a power outlet supplying AC power to the water dispenser 100. The AC power is rectified by the first power supply module 20 to generate a first DC power. The first DC power has a relatively high voltage. A portion of the first DC power can be used to implement the power-intensive functions of the water dispenser 100, such as heating and cooling drinking water. Another portion of the first DC power can be sent to the second power supply module 30 to reduce the voltage of the first DC power to generate a second DC power. The second DC power can be sent to the switch module 60.

[0049] When the switch module 60 detects the second DC power input from the second power supply module 30, the switch module 60 can control the second DC power to be supplied to the second electrical module 50 to maintain the normal operation of the second electrical module 50. The second DC power can be used to achieve functions with moderate power consumption in the drinking water equipment 100, such as filtering tap water and dispensing drinking water. The second electrical module 50 may include components for filtration and water dispensing (such as the filter module 51 or the water dispensing module 52 described below). The second DC power supplied to the second electrical module 50 can maintain the normal operation of the drinking water equipment 100 and realize functions such as heating and cooling drinking water, filtering tap water, and dispensing drinking water.

[0050] When external environmental conditions such as power outages or natural disasters occur, the mains power cannot supply power to the water dispenser 100, and the AC input module 10 cannot input AC power. At this time, the second power supply module 30 stops operating and cannot supply the second DC power to the switch module 60. The switch module 60 can control the DC input module 40 to supply the fourth DC power to the second electrical module 50. The second electrical module 50 can be driven by the fourth DC power to maintain its normal operation. The water dispenser 100 cannot perform functions with high power consumption, such as heating and cooling drinking water. However, the functions of the second electrical module 50 can still be performed, such as filtering tap water and dispensing drinking water, to maintain the normal operation of some functions of the water dispenser 100. This makes the usage scenarios of the water dispenser 100 more diverse. Even in extreme situations such as power outages or natural disasters, users can still get filtered drinking water from the water dispenser 100, which helps to improve the user's water access experience.

[0051] Combination Figure 2 and Figure 3 In some embodiments, the switch module 60 includes a first monitoring component 61 and a first switch component 62. The first switch component 62 is connected to the second power supply module 30, the DC input module 40, and the second electrical module 50. The first monitoring component 61 is configured to monitor the second DC power input to the second power supply module 30. When the circuit for the second DC power input to the second power supply module 30 is open, the first switch component 62 controls the circuit for the DC input module 40 to input the fourth DC power to the second electrical module 50 to be open, so that the fourth DC power input to the DC input module 40 drives the second electrical module 50. When the AC input module 10 cannot input AC power, the fourth DC power input to the DC input module 40 drives the second electrical module 50 to maintain the normal operation of the second electrical module 50.

[0052] For example, when there is a power outage or natural disaster, the mains power cannot supply power to the drinking water equipment 100, and the AC input module 10 cannot input AC power. At this time, the second power supply module 30 stops operating and cannot supply the second DC power to the switch module 60. The first monitoring component 61 detects that the current value of the circuit inputting the second DC power is 0, thereby determining that the circuit inputting the second DC power to the second power supply module 30 is open, and transmits the signal to the first switch component 62. At this time, the first switch component 62 can control the circuit inputting the fourth DC power from the DC input module 40 to the second electrical module 50 to be open, so that the fourth DC power can drive the second electrical module 50, ensuring the normal operation of the second electrical module 50. The functions of the second electrical module 50 can still be realized, such as filtering tap water and outputting drinking water, to maintain the normal operation of some functions of the drinking water equipment 100, making the use scenarios of the drinking water equipment 100 more diverse. Even in extreme situations such as power outages and natural disasters, users can still get filtered drinking water from the drinking water equipment 100, which helps to improve the user experience.

[0053] Combination Figure 2 and Figure 3 In some embodiments, when the circuit for inputting the second DC power to the second power supply module 30 is open, the first switch component 62 controls the circuit for inputting the fourth DC power to the second electrical module 50 from the DC power input module 40 to be closed, and controls the circuit for inputting the second AC power to the second electrical module 50 from the second power supply module 30 to be open. When the AC power input module 10 inputs AC power, the second DC power input from the second power supply module 30 is used to drive the second electrical module 50 to maintain the normal operation of the second electrical module 50, while effectively saving the power of the DC power input module 40.

[0054] For example, when the mains power supplies the water dispenser 100, the AC input module 10 inputs AC power, which is rectified by the first power supply module 20 to generate the first DC power. The first DC power has a relatively high voltage. A portion of the first DC power can be used to realize the power-consuming functions in the water dispenser 100, such as heating and cooling drinking water. Another portion of the first DC power can be sent to the second power supply module 30 to reduce the voltage of the first DC power to generate the second DC power. The second DC power can be sent to the first switching component 62.

[0055] The first monitoring component 61 detects that the circuit through which the second power supply module 30 inputs the second DC power has a current value, thereby determining that the circuit through which the second power supply module 30 inputs the second DC power is a closed circuit, and transmits the signal to the first switching component 62. The first switching component 62 can control the circuit through which the DC power input module 40 inputs the fourth DC power to the second electrical module 50 to be disconnected, and control the circuit through which the second power supply module 30 inputs the second AC power to the second electrical module 50 to be a closed circuit, so that the second DC power input from the second power supply module 30 drives the second electrical module 50 to maintain the normal operation of the second electrical module 50. At this time, all functions of the drinking water equipment 100 can operate normally.

[0056] In addition, when the second DC power input from the second power supply module 30 drives the second electrical module 50, the first switch component 62 controls the circuit of the DC power input module 40 to input the fourth DC power to the second electrical module 50 to be disconnected, preventing the second power supply module 30 and the DC power input module 40 from simultaneously supplying power to the second electrical module 50. This helps to reduce the power consumption of the DC power input module 40, and at the same time prevents the current value input to the second electrical module 50 from being too large, thus avoiding damage to the second electrical module 50 due to excessive current.

[0057] Optionally, the first monitoring component 61 can be a shunt resistor, a Hall current sensor, etc., used to monitor the current value of the circuit that inputs the second DC power to the second power supply module 30; the first switching component 62 can be a relay, etc., which is usually used in automatic control circuits. It is actually an "automatic switch" that uses a smaller current and a lower voltage to control a larger current and a higher voltage. It plays the roles of automatic adjustment, safety protection, and circuit switching in the circuit. It can control the second DC power or the fourth DC power to drive the second electrical module 50 according to the monitoring signal of the first monitoring component 61.

[0058] Combination Figure 4 In some embodiments, the switch module 60 includes a second monitoring component 63 and a second switch component 64. The second switch component 64 is connected to the second power supply module 30, the DC input module 40, and the second electrical module 50. The second monitoring component 63 is configured to monitor the fourth DC power input to the DC input module 40. When the circuit for the fourth DC power input to the DC input module 40 is closed, the second switch component 64 controls the circuit for the second power supply module 30 to input the second DC power to the second electrical module 50 to be open, preventing the DC input module 40 and the second power supply module 30 from simultaneously supplying power to the second electrical module 50. This avoids excessive current in the second electrical module 50, which could damage components and help maintain the normal operation of the second electrical module 50.

[0059] When power is restored after an external power outage, the DC input module 40 continuously supplies power to the second electrical module 50. If both the DC input module 40 and the second power supply module 30 supply power to the second electrical module 50 simultaneously, the current value within the second electrical module 50 may momentarily become too high, potentially damaging internal components. At this time, the second monitoring component 63 detects current in the circuit through which the DC input module 40 receives the fourth DC current, thus determining that this circuit is closed. The second switching component 64 can then control the circuit through which the second power supply module 30 supplies the second DC current to the second electrical module 50 to be disconnected, preventing the second power supply module 30 from supplying the second DC current to the second electrical module 50. This avoids the DC input module 40 and the second power supply module 30 simultaneously supplying power to the second electrical module 50, ensuring that the current value within the second electrical module 50 remains within the normal range. This prevents damage to the internal components of the second electrical module 50 due to excessive current, thus contributing to the normal operation of the second electrical module 50.

[0060] Furthermore, if power is restored after an external power outage, the user can first stop the DC input module 40 from supplying power to the second electrical module 50, for example, by removing the battery from the DC input module 40 or disconnecting the DC input module 40 from the backup battery pack 130. Then, the user can supply power to the water dispenser 100 through the mains power, with the AC input module 10 receiving AC power, which is then rectified and stepped down by the first power supply module 20 and the second power supply module 30 to restore all functions of the water dispenser 100.

[0061] Combination Figure 5 and Figure 6 In some embodiments, the drinking water device 100 further includes a third power supply module 70 and a third electrical module 80. The third power supply module 70 is connected to the second power supply module 30 and is used to step down the second DC power output by the second power supply module 30 to generate a third DC power. The third electrical module 80 is connected to the third power supply module 70 and can be driven by the third DC power output by the third power supply module 70. The third DC power has a lower voltage and can be used to realize functions with lower power consumption in the drinking water device 100, such as detecting the water level of the water storage structure (e.g., the purified water tank 150 and the raw water tank 140 described below), detecting the water temperature, and powering the interactive interface of the drinking water device 100. This allows the drinking water device 100 to have more diverse functions, so that users can view the specific situation of the drinking water device 100, such as obtaining information such as the water temperature and water level in the drinking water device 100, which is beneficial to improving the user experience.

[0062] Optionally, the third power supply module 70 may include a DC-DC buck converter chip. Through the rapid switching of the switching transistor, it utilizes inductors and capacitors to store energy for voltage conversion. Its core advantage lies in its high efficiency. Compared to linear regulators (such as LDOs), DC-DC buck converter chips have lower energy losses during energy conversion. Their switching mode avoids the heat waste caused by voltage differences in linear regulators. Simultaneously, DC-DC buck converter chips are characterized by high integration and small size, making them easy to install in space-constrained devices. DC-DC buck converter chips can reduce the need for heat sinks and improve system reliability.

[0063] Combination Figure 5 , Figure 6 , Figure 8 and Figure 9 In some embodiments, the third electrical module 80 includes a temperature measuring module 81 and / or a water level detection component 82. The third electrical module 80 includes a temperature measuring module 81; or, the third electrical module 80 includes a water level detection component 82; or, the third electrical module 80 includes both a temperature measuring module 81 and a water level detection component 82. The temperature measuring module 81 is used to detect the water temperature of cold water, hot water, and room temperature water in the drinking water device 100. The water level detection component 82 can be used to detect the water level in the water storage structure (e.g., the purified water tank 150 and the raw water tank 140 described below) within the drinking water device 100, ensuring that the drinking water device 100 can detect water temperature and water level in real time during normal operation, preventing overflow caused by excessively high water levels in the drinking water device 100, and also allowing users to view the water temperature within the drinking water device 100, which is beneficial for users to obtain drinking water at a suitable temperature.

[0064] For example, the water level detection component 82 may include a first water level detection component and a second water level detection component. The drinking water device 100 may include a raw water tank 140, which can be used to store tap water. The bottom of the raw water tank 140 may be provided with a first water level detection component to detect the water level in the raw water tank 140. When the first water level detection component detects that the water level in the raw water tank 140 is too low, it can remind the user to add tap water to the raw water tank 140 in time. At the same time, compared with the first water level detection component being a certain distance away from the inner bottom surface of the raw water tank, in this embodiment of the invention, the first water level detection component can be moved to the inner bottom surface of the raw water tank 140, or sink relative to the inner bottom surface of the raw water tank 140. This can ensure that the tap water in the raw water tank 140 is fully utilized, reduce the number of times the user needs to add tap water, improve the user experience, and maintain the normal operation of the drinking water device 100.

[0065] The drinking water equipment 100 may also include a purified water tank 150, which is used to store drinking water filtered by a filtration component (such as the filtration module 51 described below). The top of the purified water tank 150 may be provided with a second water level detection component to detect the water level in the purified water tank 150. When the second water level detection component detects that the water level in the purified water tank 150 is high, it can stop the continuous supply of water to the purified water tank to prevent water overflow in the purified water tank 150 from damaging other components, which is beneficial to ensuring the electrical safety of the drinking water equipment 100.

[0066] In addition, the temperature measuring module 81 can be used to detect the temperature of hot water, cold water and room temperature water in the water dispenser 100. For example, the drinking water in the water purification tank 150 is room temperature water. Part of the temperature measuring module 81 can be set in the water purification tank 150 to detect the temperature of the room temperature water, so that users can get the drinking water at the required temperature. This is suitable for various scenarios such as making milk, making tea and drinking directly, and avoids scalding caused by excessively hot drinking water. At the same time, if the temperature measuring module 81 detects that the water temperature is continuously too high or cannot heat up, it can promptly check the fault in the water dispenser 100, which is conducive to timely maintenance of the water dispenser 100.

[0067] Combination Figure 5 , Figure 6 , Figure 8 and Figure 9 In some embodiments, the drinking water device 100 further includes a switch module 60 and an interaction module 90. The switch module 60 is connected to a third power supply module 70 and can be driven by a third DC power output from the third power supply module 70. The interaction module 90 is also connected to the third power supply module 70 and can be driven by the third DC power output from the third power supply module 70. The switch module 60 controls the overall operation of the drinking water device 100, and the interaction module 90 may include an interactive interface where the user can select a specific function. This allows the switch module 60 to receive a signal and control the components within the drinking water device 100 to perform that specific function. The second DC power is stepped down by the third power supply module 70 to generate a third DC power. Since the switch module 60 and the interaction module 90 only require a lower voltage to operate normally, the third DC power is used to drive them, maintaining their normal operation and preventing electrical faults caused by high-voltage power supply. This also helps reduce the energy consumption of the drinking water device 100.

[0068] Optionally, the drinking water device 100 may also include a microcontroller unit (MCU), which can integrate all the core components (central processing unit, memory, input / output interface, etc.) of the drinking water device 100 onto a single chip to control the components of the drinking water device 100 that perform different functions.

[0069] Combination Figure 5 and Figure 6 In some embodiments, the drinking water device 100 further includes a first electrical module 110, which is connected to a first power supply module 20. The first electrical module 110 can be driven by a first direct current output from the first power supply module 20. The drinking water device 100 can perform functions such as heating and cooling drinking water, which typically require high-voltage direct current. When AC power is supplied to the AC input module 10, the AC power is rectified by the AC input module 10 to generate first direct current. This first direct current has a high voltage; a portion of it can be used to drive the first electrical module 110 to perform power-intensive functions in the drinking water device 100, such as heating and cooling drinking water. Another portion of the first direct current can be supplied to the second power supply module 30 to reduce its voltage and generate second direct current.

[0070] Combination Figure 6 , Figure 9 and Figure 11 In some embodiments, the first electrical module 110 includes a heating module 111 and / or a cooling module 112. Specifically, the first electrical module 110 includes a heating module 111; or, the first electrical module 110 includes a cooling module 112; or, the first electrical module 110 includes both a heating module 111 and a cooling module 112. The heating module 111 heats the drinking water in the purified water tank 150 to generate hot water; the cooling module 112 cools the drinking water in the purified water tank 150 to generate cold water. When AC power is input into the AC power input module 10, the cooling module 112 and the heating module 111 operate normally, allowing users to obtain drinking water at the desired temperature from the drinking water device 100, thus improving the user's water-collecting experience. When a power outage or other external event occurs, the first power supply module 20 stops operating and cannot generate the first DC power, causing the heating module 111 and the cooling module 112 to stop operating.

[0071] For example, the heating module 111 includes a heating tank, into which drinking water in the purified water tank 150 can be supplied for heating to generate hot water. Since the heating tank consumes a significant amount of electrical energy when heating drinking water, a first direct current can supply power to the heating tank to electrically heat the drinking water, thereby generating hot water. Additionally, the cooling module 112 may include a cold tank 1121 and cooling components (such as the compressor 1122, evaporator, condenser 1123, etc. described below). The refrigerant in the cooling components can absorb heat from the drinking water in the cold tank 1121, thereby cooling the drinking water in the cold tank 1121 to generate cold water. Since the cold tank 1121 consumes a significant amount of electrical energy when cooling drinking water, a first direct current can supply power to the cooling components to drive the flow of the refrigerant. As the refrigerant passes through the cold tank 1121, it absorbs heat from the drinking water in the cold tank 1121, lowering the temperature of the drinking water and generating cold water.

[0072] Combination Figure 9 and Figure 10 In some embodiments, the first electrical module 110 includes a refrigeration module 112, which includes a cold tank 1121, a compressor 1122, an evaporator, a condenser 1123, and a cooling fan 1124. The compressor 1122, the evaporator, and the condenser 1123 are connected to form a refrigerant circuit to allow the refrigerant to switch between gaseous and liquid states. The evaporator is heat exchanged with the cold tank 1121. The evaporator can be located on the outer wall of the cold tank 1121. When the low-temperature liquid refrigerant flows in the evaporator, it can absorb heat from the drinking water in the cold tank 1121 to generate cold water. The refrigerant that has absorbed heat is converted into gaseous refrigerant and flows into the condenser 1123 to release heat. The gaseous refrigerant is converted into liquid refrigerant. After being pressurized by the compressor 1122, the liquid refrigerant is reintroduced into the evaporator to absorb heat, thus realizing the refrigerant circulation loop.

[0073] In addition, the cooling fan 1124 and the condenser 1123 are opposite each other in the vertical direction, and the cooling fan 1124 is located below the condenser 1123. The cooling fan 1124 is configured to drive the airflow from top to bottom through the condenser 1123 and to drive the airflow out from the side of the water dispenser 100. After the liquid refrigerant absorbs heat, it is converted into gaseous refrigerant and flows to the condenser 1123 to release heat. The temperature of the condenser 1123 rises. The cooling fan 1124 drives the airflow through the condenser 1123, which helps to accelerate the heat dissipation of the condenser 1123. At the same time, the airflow absorbs heat when it flows through the condenser 1123, forming a hot airflow with a higher temperature. The hot airflow is output from the side of the water dispenser 100 to prevent the hot airflow from blowing onto the support surface of the water dispenser 100 (such as a tabletop, wooden countertop, etc.) and causing corrosion to the support surface.

[0074] In some embodiments, the condenser 1123 includes an airflow channel extending vertically. The inlet of the cooling fan 1124 is opposite to the airflow channel in the vertical direction, which helps to increase the heat exchange area between the airflow and the condenser 1123, thereby accelerating the heat dissipation of the condenser 1123. The outer side of the water dispenser 100 is provided with an air inlet, which can be opposite to the compressor 1122 in the left-right direction. The cooling fan 1124 can draw in airflow from the air inlet. After passing through the compressor 1122, the airflow flows downwards through the airflow channel of the condenser 1123 to absorb heat from the compressor 1122 and the condenser 1123. Multiple heat dissipation fins can be provided in the airflow channel to increase the heat exchange area between the airflow and the condenser 1123, thereby enhancing the heat exchange effect. After absorbing heat, the airflow forms a hot airflow, which enters from the inlet of the cooling fan 1124 and exits from the outlet of the cooling fan 1124, so that the hot airflow is quickly discharged from the water dispenser 100, preventing heat from accumulating inside the water dispenser 100.

[0075] In some embodiments, the outer side of the water dispenser 100 is provided with a heat dissipation vent, and the outlet of the cooling fan 1124 is opposite to the heat dissipation vent. When the airflow flows through the compressor 1122 and the condenser 1123, it absorbs the heat from the compressor 1122 and the condenser 1123. The heat-absorbing airflow forms a hot airflow with a higher temperature. The hot airflow is output from the outlet of the cooling fan 1124 and discharged to the outside from the heat dissipation vent. Compared with the heat dissipation vent of the water dispenser 100 located at the bottom of the water dispenser 100, the water dispenser 100 of the present invention can avoid heat accumulation at the bottom of the water dispenser 100, which is conducive to the timely discharge of hot airflow from the heat dissipation vent of the water dispenser 100. At the same time, it avoids the hot airflow from blowing directly onto the support surface of the water dispenser 100 (such as a tabletop, wooden tabletop, etc.), which could lead to corrosion and damage to the support surface.

[0076] Optionally, the cooling fan 1124 can be a centrifugal fan, configured with axial intake and radial exhaust. The vertical direction is the axial direction of the centrifugal fan, and the horizontal or front-back direction is the radial direction. The centrifugal fan has a compact structure, saving space, and the outlet direction is adjustable; the use of a volute and impeller can effectively reduce operating noise.

[0077] Combination Figure 9 and Figure 10In some embodiments, the compressor 1122 is located above the condenser 1123, and there is a gap between the compressor 1122 and the condenser 1123 to prevent the compressor 1122 and the condenser 1123 from colliding. At the same time, it is beneficial for the airflow to flow through the gap and into the airflow channel of the condenser 1123, thereby increasing the heat exchange area between the airflow and the condenser 1123. Furthermore, the minimum distance between the compressor 1122 and the condenser 1123 in the vertical direction is not greater than twice the thickness of the condenser 1123, to prevent the vertical distance between the compressor 1122 and the condenser 1123 from being too large, which is beneficial to improving the compactness of the distribution of the compressor 1122 and the condenser 1123.

[0078] Combination Figure 9 and Figure 10 In some embodiments, the compressor 1122 is located above the condenser 1123, the cold tank 1121 is located above the compressor 1122, and the cooling fan 1124 is located below the condenser 1123. This arrangement makes the compressor 1122, condenser 1123, cold tank 1121, and cooling fan 1124 more compact, which is beneficial to improving the integration of the refrigeration module 112. Compared to the condenser 1123 and cooling fan 1124 being located to the side of the compressor 1122, the refrigeration module 112 of this embodiment can reduce the lateral displacement of the water dispenser 100 (see reference). Figure 9 The size of the water dispenser (in the left and right directions) is adjusted to reduce the space occupied by the water dispenser 100.

[0079] Combination Figures 6 to 9 as well as Figure 11 In some embodiments, the second electrical module 50 includes a filter module 51 and / or a water outlet module 52. The second electrical module 50 includes a filter module 51; or, the second electrical module 50 includes a water outlet module 52; or, the second electrical module 50 includes both a filter module 51 and a water outlet module 52. The filter module 51 is used to filter tap water in the raw water tank 140, and the water outlet module 52 is used to output drinking water. When AC power is input into the AC power input module 10, or a fourth DC power is input into the DC power input module 40, the normal operation of the filter module 51 and the water outlet module 52 can be maintained, ensuring that users can smoothly obtain filtered drinking water, improving the user's water-collecting experience, and making the usage scenarios of the drinking water device 100 more diversified.

[0080] For example, the filtration module 51 includes a composite filter element for filtering tap water in the raw water tank 140. The drinking water device 100 also includes a booster pump for delivering tap water from the raw water tank 140 to the composite filter element for filtration. Driven by a second or fourth DC power supply, the booster pump pumps the tap water into the composite filter element for thorough filtration to produce drinking water, which is stored in the purified water tank 150.

[0081] The water outlet module 52 includes a valve assembly and an outlet pipe. The valve assembly controls the outlet pipe to output hot water, cold water, or room temperature water. The drinking water equipment 100 also includes a water pump. When the user draws room temperature water, the drinking water in the purified water tank 150 is room temperature water. Driven by a second or fourth DC power supply, the water pump can pump the drinking water in the purified water tank 150 to the valve assembly so that the outlet pipe outputs room temperature water. When the user draws hot water, driven by a second or fourth DC power supply, the water pump can pump the drinking water in the purified water tank 150 to the hot water tank and drive the hot water in the hot water tank to output to the valve assembly so that the outlet pipe outputs hot water. When the user draws cold water, driven by a second or fourth DC power supply, the water pump can pump the drinking water in the purified water tank 150 to the cold water tank 1121 and drive the cold water in the cold water tank 1121 to output to the valve assembly so that the outlet pipe outputs cold water.

[0082] Furthermore, when AC power is input into the AC power input module 10, all functions of the drinking water device 100 operate normally. When there is a power outage or other external environmental conditions, the AC power input module 10 cannot input AC power, and the fourth DC power from the DC power input module 40 can drive the filter module 51 and the water outlet module 52 to maintain the normal operation of the filter module 51 and the water outlet module 52, ensuring that users can smoothly obtain filtered drinking water, improving the user's water consumption experience, and making the use scenarios of the drinking water device 100 more diversified.

[0083] In some embodiments, the AC input module 10 is used to input AC power with a voltage between 220V and 110V. The AC voltage can be 110V, 150V, 200V, 220V, etc. When the mains power supplies the water dispenser 100, the AC input module 10 inputs AC power between 220V and 110V. After rectification by the first power supply module 20, the AC power generates a higher voltage first DC power. Compared to using low-voltage electricity to achieve cooling and heating functions, under the premise that the cooling and heating power of the water dispenser 100 remains unchanged, using the first DC power to achieve the functions of cooling and heating drinking water can reduce the current transmitted in the circuit when the water dispenser 100 is cooling and heating, which helps to reduce the power loss of current in the circuit transmission, thereby improving the overall energy utilization efficiency.

[0084] In some embodiments, the second power supply module 30 is used to input DC power with a voltage between 12V and 36V. The voltage of the second DC power supply can be 12V, 24V, 36V, etc. Compared to the second power supply module 30 being used to input high-voltage power, DC power between 12V and 36V is a safe voltage, with a lower risk of electric shock, which helps ensure the electrical safety of the drinking water equipment 100. Simultaneously, the second DC power supply is mainly used to drive the second electrical module 50, which mainly includes a filter module 51 and a water outlet module 52. The driving voltage of the filter module 51 and the water outlet module 52 is relatively low, eliminating the need for high-voltage driving. Using 12V to 36V DC power to drive the second electrical module 50 helps save power consumption of the drinking water equipment 100 and reduces energy consumption.

[0085] Combination Figure 8 and Figure 12 In some embodiments, the second power supply module 30 includes a USB external interface 120. The USB external interface 120 is used to electrically connect an external backup battery pack 130 to the second power supply module 30 via a charging cable, so that the backup battery pack 130 supplies power to the second power supply module 30. Specifically, when there is a power outage or other situation where the mains power cannot supply power to the water dispenser 100, the backup battery pack 130 is connected via the USB external interface, and the backup battery pack 130 supplies power to the second power supply module 30, enabling the second power supply module 30 to generate a second direct current. This second direct current can be used to drive the second electrical module 50 to achieve functions such as filtration and water dispensing in the water dispenser 100.

[0086] In addition, the second power supply module 30 is connected to the third power supply module 70. The second DC power can also be supplied to the third power supply module 70 and stepped down by the third power supply module 70 to generate the third DC power, which is used to drive the third electrical module 80, thereby realizing the functions of temperature measurement and water level detection in the water drinking device 100. The third DC power can also drive the interactive module 90, which helps to maintain the normal display of the interactive interface in the water drinking device 100, so that users can view the status inside the water drinking device 100. Even in the event of a power outage, the water drinking device 100 can still be connected to the backup battery pack 130 through the USB external interface 120 to maintain the normal operation of the filtration, water dispensing, temperature measurement, water level detection, and interactive interface display functions inside the water drinking device 100. Users can get filtered drinking water from the water drinking device 100 and can also view the status inside the water drinking device 100 through the interactive interface, which helps to improve the user experience and expand the application scenarios of the water drinking device 100.
