Description

TECHNICAL FIELD

[0001] The utility model relates to the controllable silicon heat dissipation structure of water dispenser. BACKGROUND

[0002] With the improvement of people's living standards, water dispenser has become a widely used household appliance in daily life. Water dispenser not only can provide cold and hot water, but also can meet more scene demand, such as fast heating function. However, in the actual use of water dispenser, in order to realize the efficient control of water heating device, it is usually necessary to use electronic components such as thyristor to realize the start-stop and temperature regulation of water heating device.

[0003] As the core control component of water dispenser, thyristor has the advantages of high working voltage, high control precision and fast response speed. However, in the long running process of water dispenser, thyristor will generate a lot of heat. If the heat cannot be dissipated in time and effectively, it may cause the performance of thyristor to decline, and even cause failure or safety hazard. Therefore, heat dissipation design has become one of the key problems that cannot be ignored in water dispenser.

[0004] The traditional heat dissipation methods mainly include the following:

[0005] Natural heat dissipation: rely on the natural air flow around the thyristor to dissipate heat, but the heat dissipation efficiency is limited, which is difficult to meet the demand of high-power equipment.

[0006] Air cooling heat dissipation: install heat dissipation fan in the equipment to enhance air flow, so as to improve the heat dissipation efficiency. However, air cooling heat dissipation will increase the energy consumption and noise of the equipment, which does not meet the requirements of modern energy saving and environmental protection.

[0007] External liquid cooling heat dissipation: use external cooling liquid circulation to take away heat, which has significant heat dissipation effect, but the structure is complex and the maintenance cost is high, which is not suitable for household water dispenser.

[0008] In the traditional technology, the heat dissipation structure design is often independent of the heating system of water dispenser, which leads to large equipment size, complex structure and limited heat dissipation efficiency.

[0009] Therefore, it is necessary to propose a more efficient and compact thyristor heat dissipation structure to improve the heat dissipation performance and optimize the design of water dispenser. Utility model content

[0010] The utility model aims at providing a kind of thyristor heat dissipation structure of water dispenser for realizing efficient heat dissipation.

[0011] The utility model is realized as follows:

[0012] A thyristor heat dissipation structure for a water dispenser includes a base, a water heating device for heating water, a main control board, a faucet, a radiator, and a thyristor. The water heating device is disposed inside the base, the inlet of the water heating device extends out of the base and is connected to an external water source, and the outlet of the water heating device is connected to the faucet.

[0013] The water heating device is electrically connected to the main control board, and the main control board controls the start and stop of the water heating device.

[0014] The radiator is provided with a water channel for connecting to a water source, and the thyristor is attached to the radiator, and the thyristor and the radiator exchange heat.

[0015] When external water flows through the water channel, the radiator exchanges heat with the water, thus achieving heat dissipation of the thyristor.

[0016] By utilizing the design of the radiator and water channels, when external water flows through the water channels of the radiator, the water flow carries away the heat on the radiator, thereby achieving efficient heat dissipation of the thyristor. This avoids the problem of low efficiency in traditional natural heat dissipation and improves the stability and durability of the equipment.

[0017] By integrating the radiator with the water system, the water dispenser's own water circulation system is fully utilized, eliminating the need for additional fans or external cooling equipment. This reduces the size and complexity of the device while optimizing the overall structural layout.

[0018] By naturally removing heat through water flow, there is no need for additional electricity to drive the cooling equipment, thus reducing energy consumption. At the same time, it avoids the noise and maintenance requirements of air cooling, which is more in line with the energy-saving and environmentally friendly trend of modern home appliances.

[0019] Effective heat dissipation control avoids performance degradation or damage to the thyristor due to overheating, ensuring the safety and reliability of the water dispenser during long-term operation.

[0020] The objective of this utility model can also be achieved by the following technical measures:

[0021] Furthermore, the water heating device includes a first water heating device and a second water heating device, the radiator includes a first radiator and a second radiator, and the thyristor includes a first thyristor and a second thyristor.

[0022] The main control board is provided with a first main control unit for controlling the first water heating device and a second main control unit for controlling the second water heating device;

[0023] The first thyristor is connected to the first main control unit, the first radiator is provided with a first water channel for connecting to a water source, the first thyristor is in close contact with the first radiator, and the first thyristor and the first radiator exchange heat.

[0024] The second thyristor is connected to the second main control unit, the second radiator is provided with a second water channel for connecting to a water source, the second thyristor is in close contact with the second radiator, and the second thyristor and the second radiator exchange heat.

[0025] When external water flows through the first water channel and the second water channel, the first radiator and the second radiator exchange heat with the water respectively, thereby achieving heat dissipation of the first and second thyristors.

[0026] By setting up a first heat sink and a second heat sink to dissipate heat from the first and second thyristors respectively, the independent heat dissipation path and distributed heat dissipation design are achieved, avoiding heat concentration and improving the overall heat dissipation efficiency.

[0027] The first main control unit works with the first thyristor to control the first water heating device, and the second main control unit works with the second thyristor to control the second water heating device. The independent control and heat dissipation design ensures the stable operation of each water heating device and avoids equipment failure caused by single-point overheating.

[0028] The water flows through the first and second water channels to exchange heat with the radiator, directly utilizing the cooling capacity of the flowing water to achieve efficient heat dissipation. This avoids the need for additional heat dissipation devices or the introduction of energy consumption, making it energy-saving and environmentally friendly.

[0029] The first and second water heating devices achieve a compact layout through their respective independent heat dissipation systems, making full use of the internal space of the base, reducing the size of the equipment, and improving the overall performance of the equipment.

[0030] Furthermore, it also includes a cooling fan, the base has air inlet and outlet, and the cooling fan is installed inside the base and electrically connected to the main control board.

[0031] By adding a cooling fan inside the base, along with the design of the air inlet and outlet, air circulation is effectively enhanced, heat dissipation efficiency is improved, and the heat generated by the internal equipment (especially the SCR and water heating device) is dissipated more quickly, thereby preventing the equipment from being damaged due to overheating.

[0032] The cooling fan provides active cooling, further complementing the passive cooling function of the water channels and radiators, ensuring that the equipment can operate stably for a long time under high load conditions and extending the service life of the equipment.

[0033] The cooling fan is electrically connected to the main control board. Through intelligent control, the fan's operating status is automatically adjusted according to temperature changes, thereby achieving energy-saving control, avoiding energy waste from long-term high-load operation of the fan, and optimizing energy use efficiency.

[0034] The cooling effect of the fan keeps the temperature within a reasonable range, which helps the internal components of the system to work stably, avoids circuit instability or failure caused by excessive temperature, and improves the overall reliability of the equipment.

[0035] The fan cooling design not only improves the performance of the equipment, but also avoids overheating through effective thermal management, ensuring the safety and comfort of the water dispenser during long-term use and enhancing the user experience.

[0036] Furthermore, it also includes an inlet pipe, a water pump, and a drain pipe, which are placed inside the machine base. The inlet pipe passes through a first water channel and a second water channel. The inlet of the inlet pipe extends out of the machine base to connect to a water source. The outlet of the inlet pipe is connected to the inlet of the water pump. The outlet of the water pump is connected to the inlet of a first water heating device. The outlet of the first water heating device is connected to the inlet of the drain pipe. The outlet of the drain pipe is connected to the inlet of a second water heating device.

[0037] The introduction of water pumps ensures that water can be delivered to the first and second water heating devices at a stable flow rate and pressure, and can supply water normally even in low water pressure environments, thus guaranteeing the hot water output capacity and overall working efficiency of the equipment.

[0038] The water inlet pipe passes through the first water channel and the second water channel. When the water flows through the water channel, it exchanges heat with the radiator, so that the water is preheated before entering the first water heating device. This reduces the heating load of the heating device, improves thermal efficiency, and further saves energy and reduces consumption.

[0039] The drain pipe connects the first and second water heating devices, enabling staged heating of the water. The first water heating device provides initial heating, while the second water heating device provides precise heating, resulting in a more stable and accurate output of hot water to meet users' needs for different temperatures.

[0040] The water inlet extends beyond the base, allowing for easy connection to various external water sources, including municipal water pipes or water storage devices. This enhances the equipment's adaptability, making it suitable for homes, offices, and other scenarios with diverse water supply conditions.

[0041] The beneficial effects of this utility model are as follows:

[0042] This invention utilizes the design of a radiator and water channels. When external water flows through the water channels of the radiator, the water carries away the heat from the radiator, thereby achieving efficient heat dissipation of the thyristor. This avoids the problem of low efficiency in traditional natural heat dissipation and improves the stability and durability of the equipment.

[0043] This invention integrates the radiator with the water system, making full use of the water circulation system of the water dispenser itself. It eliminates the need for additional fans or external cooling equipment, reducing the size and complexity of the equipment while optimizing the overall structural layout.

[0044] This invention uses water flow to naturally remove heat, eliminating the need for additional electricity to drive the cooling device, thus reducing energy consumption. It also avoids the noise and maintenance requirements of air cooling, making it more in line with the energy-saving and environmentally friendly trend of modern home appliances.

[0116] Water vapor separation principle

[0117] Water vapor separator 9 design: The water faucet 6 has a built-in water vapor separator 9, which achieves efficient water vapor separation through the special structure of the box 91;

[0118] Inclined surface 92 guides the flow: After hot water enters the box 91 through the hot water inlet 911, it flows along the inclined surface 92 to the blocking block 20.

[0119] Separate channel design:

[0120] The first hot water channel 201 and the second hot water channel 202 are located at different heights, so that hot water is preferentially discharged from the lower outlet.

[0121] The inlet of the exhaust passage 203 is higher than the inlets of the first hot water passage 201 and the second hot water passage 202, so the high-temperature water vapor naturally escapes along the exhaust passage 203, avoiding mixing with the hot water.

[0122] Function of blocking block 20: Block 20 separates hot water and water vapor, further preventing water vapor from mixing and improving the purity of hot water output.

[0123] Enhanced separation by baffles: The baffles installed on the inner wall of the hot water channel 313 ensure even water flow, slow down the water flow speed, and effectively separate water vapor.

[0124] The exhaust outlet 101 is connected to the outside, continuously discharging water vapor to ensure a stable and pure water flow.

[0125] Through the above operations and design, the water dispenser can achieve multiple functions such as tea brewing and disinfection, and effectively prevent water vapor mixing, thereby improving user experience and equipment efficiency.

[0126] In other embodiments, the heating tube 311 includes a hollow conduit 314 for water to pass through, an insulating layer 315, and an electromagnetic coil, wherein the insulating layer 315 is disposed around the hollow conduit 314.

[0127] The electromagnetic coil is wound on the insulating layer 315, the clamping cavity 301 clamps the electromagnetic coil, and the electromagnetic coil is electrically connected to the power supply terminal 50.

[0128] The electromagnetic coil generates a changing magnetic field when energized, which penetrates the hollow conduit 314 and induces eddy currents. The eddy currents in the hollow conduit 314 generate heat due to the resistance of the metal, which heats the water passing through the hollow conduit 314.
