Description

Technical Field

[0001] This application relates to the field of water treatment equipment technology, specifically to a water purification device and its temperature control method and apparatus. Background Technology

[0002] Water purification equipment is used to remove impurities, bacteria, heavy metals, and other harmful substances from water, providing drinking water that meets standards and is safe for consumption. However, because water purification equipment is usually installed near water sources, its operating environment is often quite humid. Condensation easily forms in the internal pipes, leading to excessive humidity. This high humidity not only promotes bacterial growth but also accelerates the corrosion of electrical and metal components, shortening the equipment's lifespan. It also increases safety hazards such as electrical leaks, fires, and short circuits. Furthermore, the overly humid and warm environment inside the water purifier can attract animals, potentially threatening the quality of the purified water.

[0003] Therefore, how to design effective dehumidification and insect repellent mechanisms to ensure that water purification equipment can maintain efficient and safe operation in various complex installation environments has become an urgent problem to be solved. Summary of the Invention

[0052] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed description. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0053] Understandably, with increasing public awareness of drinking water safety, large commercial water purifiers are being installed in crowded places such as airports, high-speed rail stations, and companies. While providing convenience, these commercial water purifiers also present some problems. Due to their intended use, water purifiers are typically installed close to water sources, resulting in high humidity. Prolonged exposure to high humidity causes condensation to form on the exterior of the internal pipes, especially during rainy or humid weather, when internal humidity can exceed 95%. Firstly, high humidity not only fosters bacterial growth in the internal pipes but also shortens the lifespan of electrical components such as the main control board, display board, and internal electrical loads. Metal components inside the purifier may rust, potentially leading to dangerous situations like electrical leaks, sparks, and short circuits. Secondly, the warm and humid environment inside commercial water purifiers attracts small animals like cockroaches and rats, whose bacteria can contaminate the purified water.

[0054] Most existing water purifiers do not have dehumidification functions. Most water purifiers are installed in well-ventilated environments to ensure good air circulation and reduce humidity. However, some water purifiers are limited by their installation environment and have to be installed in closed and humid environments, which can easily breed pests. If the driving agents in the water purifier are misused, it may affect water safety.

[0055] Please see Figure 1 This application provides a water purification device, which includes: a first chamber, a second chamber, a temperature regulating device 11, a first temperature sensing device 21 and a first humidity sensing device (not shown) disposed in the first chamber, and a second temperature sensing device 31 and a second humidity sensing device (not shown) disposed in the second chamber; the effective working area of ​​the temperature regulating device 11 at least partially covers the first chamber and the second chamber.

[0056] The temperature regulating device 11 can alternately heat one of the first chamber and the second chamber while cooling the other, provided that the first temperature detected by the first temperature sensor 21, the second temperature detected by the second temperature sensor 31, the first humidity detected by the first humidity sensor, and the second humidity detected by the second humidity sensor meet the first environmental conditions. This creates a temperature gradient between the first and second chambers. By alternately heating and cooling the first and second chambers, the unstable temperature and humidity inside the chambers disrupt the suitable living environment for pests, achieving an insect-repelling effect and also helping to regulate the humidity in each chamber.

[0057] Specifically, water purification equipment includes, but is not limited to, countertop water purifiers, direct drinking water machines, faucet-type water purifiers, central water purifiers, commercial direct drinking water machines, catering-specific water purifiers, industrial ultrafiltration water purification equipment, EDI ultrapure water equipment, and so on.

[0058] In one embodiment, the water purification device includes at least two chambers. In this embodiment, a partition device is provided to divide the inner cavity of the water purification device into a first chamber and a second chamber.

[0059] Alternatively, the dividing device can be a flexible partition or a telescopic plate, etc.

[0060] Specifically, the water purification equipment also includes a control device 12, which is electrically connected to the temperature regulating device 11. The control device 12 is also electrically connected to a first temperature sensor 21, a first humidity sensor, a second temperature sensor 31, and a second humidity sensor. The first temperature sensor 21 is used to acquire a first temperature T1 of the first chamber, and the control device 12 is used to receive the first temperature T1. The second temperature sensor 31 is used to acquire a second temperature T2 of the second chamber, and the control device 12 is used to receive the second temperature T2. The first humidity sensor is used to acquire a first humidity H1 of the first chamber, and the control device 12 is used to receive the first humidity H1. The second humidity sensor... The control device 12 is used to obtain the second humidity H2 of the second chamber. The control device 12 is used to receive the second humidity H2 and to determine whether the first temperature T1, the second temperature T2, the first temperature H1 and the second temperature H2 meet the first preset temperature condition to obtain the first comparison result. If the first comparison result indicates that the first temperature T1, the second temperature T2, the first temperature H1 and the second temperature H2 meet the first preset temperature condition, the control device 12 alternately increases one of the first temperature and the second temperature and decreases the other. If the first comparison result indicates that the first temperature T1, the second temperature T2, the first temperature H1 and the second temperature H2 do not meet the first preset temperature condition, the temperature regulating device 11 operates without load.

[0061] In one possible implementation, the first environmental condition is characterized by a first temperature T1 and a second temperature T2 satisfying a first preset temperature condition, and a first temperature H1 and a second temperature H2 being greater than the first preset temperature. In another possible implementation, the first environmental condition is characterized by either the first temperature T1 or the second temperature T2 satisfying the first preset temperature condition, and a first temperature H1 and a second temperature H2 being greater than the first preset temperature. In yet another possible implementation, the first environmental condition is characterized by either the first temperature T1 or the second temperature T2 satisfying the first preset temperature condition, and a first temperature H1 or a second temperature H2 being greater than the first preset temperature. For example, in the embodiments of this specification, the first preset temperature condition is 20℃-30℃, the first preset temperature is 70%, and the first environmental condition is that the first temperature T1 or the second temperature T2 is between 20℃ and 30℃, and the first temperature H1 or the second temperature H2 is greater than 70%.

[0062] In one possible implementation, the control device 12 is disposed in the inner cavity of the water purification device; in another possible implementation, the control device 12 is disposed on a terminal and is communicatively connected to the temperature regulating device 11.

[0063] In one embodiment, the temperature regulating device 11 can act independently on the first chamber and the second chamber to regulate the first temperature and the second temperature; in another embodiment, the temperature regulating device 11 can act together on the first chamber and the second chamber to regulate the first temperature and the second temperature.

[0064] In one embodiment, the temperature regulating device 11 is disposed on the bottom wall of the inner cavity of the water purification device; in another embodiment, the temperature regulating device 11 is disposed on the side wall of the inner cavity of the water purification device; in yet another embodiment, the temperature regulating device 11 is disposed on the top wall of the inner cavity of the water purification device.

[0065] Furthermore, the water purification equipment also includes a partition 1, which is disposed between the first chamber and the second chamber, and the temperature regulating device 11 includes a semiconductor cooling chip;

[0066] The semiconductor cooling chip includes a first surface and a second surface, with the first surface facing the first chamber and the second surface facing the second chamber;

[0067] The semiconductor cooling element can alternately heat one of the first chamber and the second chamber while simultaneously cooling the other, provided that the first temperature detected by the first temperature sensor 21, the second temperature detected by the second temperature sensor 31, the first humidity detected by the first humidity sensor, and the second humidity detected by the second humidity sensor meet the first environmental conditions. This creates a temperature gradient between the first and second chambers. By alternating between heating and cooling the first and second chambers using the semiconductor cooling element, the structure of the purification equipment is simplified, and the dehumidification and insect-repelling effects are improved.

[0068] Specifically, the temperature regulating device 11 includes a thermoelectric cooler (TEC), also known as a Peltier element. Based on the Peltier effect, a thermoelectric cooler cools one side and heats the other by applying an electric current, and this process can be reversed by changing the direction of the current. The thermoelectric cooler is internally composed of multiple thermocouple pairs made up of N-type and P-type semiconductors. When direct current passes through these semiconductor materials, the movement of electrons and holes carries away heat, causing one side of the thermoelectric cooler to absorb heat and the other side to release heat. If the direction of the current is changed, the direction of heat absorption and release is reversed; the side that was previously cooled becomes the heating side, and the side that was previously heated becomes the cooling side.

[0069] In one embodiment, the thermoelectric cooler is disposed on the partition 1, with the first side of the thermoelectric cooler facing the first chamber and the second side facing the second chamber; in another embodiment, the partition 1 is used to divide the inner cavity of the water purification device into the first chamber and the second chamber, and the thermoelectric cooler is installed on the bottom wall, side wall or top wall of the inner cavity. In this case, the thermoelectric cooler is not restricted by the partition 1, which facilitates heat dissipation and maintenance.

[0070] In one embodiment, the partition 1 is provided with a receiving position for placing the thermoelectric cooler, and the receiving position is located near the bottom plate of the water purification equipment. In this way, the receiving position helps to homogenize the internal temperature of the first chamber and the second chamber, avoids heat from directly circulating back to the thermoelectric cooler, improves the temperature control effect, and leaves other space in each chamber for the placement of other components.

[0071] Specifically, the receiving position is a hollow structure, and the receiving position is provided with a mounting slot, which can be engaged with the semiconductor cooling chip.

[0072] Specifically, partition 1 is made of ABS, PC or foam ceramic.

[0073] In one embodiment, the partition 1 is located at the central axis of the base plate to divide the inner cavity of the water purification device into a uniform first chamber and a second chamber.

[0074] Furthermore, the water purification equipment also includes a first heat dissipation component 22, a first fan 23, a second heat dissipation component 32, and a second fan 33;

[0075] The first heat dissipation component 22 and the first fan 23 are housed in the first cavity and are fixedly connected. The first heat dissipation component 22 and the first fan 23 are housed in the second cavity and are fixedly connected.

[0076] The first heat dissipation component 22 is attached to the first surface, and the second heat dissipation component 32 is attached to the second surface. The first fan 23 is used to deliver airflow to the first chamber, and the second fan 33 is used to deliver airflow to the second chamber. By attaching the first heat dissipation component 22 to the first surface of the thermoelectric cooler and the second heat dissipation component 32 to the second surface, the thermoelectric cooler can quickly absorb or release heat, improving cooling and heating efficiency and accelerating the temperature regulation process.

[0077] Specifically, the first fan 23 delivers airflow to the first chamber, and the second fan 33 delivers airflow to the second chamber, which can increase airflow, accelerate heat diffusion and exchange, make temperature regulation more uniform, and prevent local overheating or overcooling. The first heat dissipation component 22 is the first heat sink, and the second heat dissipation component 32 is the second heat sink. The second heat sink is located between the second side and the second fan.

[0078] Specifically, the first radiator, the first fan 23, the second radiator, and the second fan 33 are electrically connected to the control device 12. The control device 12 is used to control the operating parameters of the first radiator, the first fan 23, the second radiator, and the second fan 33, wherein the operating parameters include the operating power.

[0079] Specifically, the bearings of the first fan 23 and the second fan 33 are silent bearings.

[0080] Furthermore, the water purification equipment also includes a control circuit, which is connected to the temperature regulating device 11. The control circuit includes a first switch, a second switch, a third switch, and a fourth switch.

[0081] When the first switch and the third switch are turned on, the current direction of the temperature regulating device 11 is the first direction;

[0082] With the second and fourth switches on, the current direction of the temperature regulating device 11 is the second direction. By adjusting the on / off state of the control circuit at different times, the control circuit can dynamically adjust the intensity of cooling and heating, thereby controlling the temperature gradient between the first and second chambers to meet the precise requirements of the water purification equipment for ambient temperature.

[0083] Specifically, the control circuit is an H-bridge circuit. The H-bridge circuit can change the current direction by different combinations of switch conduction, thus enabling the thermoelectric cooler to both cool and heat. When the first and third switches are on, the current direction of the H-bridge circuit is the first direction, and the first surface of the thermoelectric cooler is the heating surface, while the second surface is the cooling surface. When the second and fourth switches are on, the current direction of the H-bridge circuit is the second direction, and the first surface of the thermoelectric cooler is the cooling surface, while the second surface is the heating surface.

[0084] Specifically, the first switch, the second switch, the third switch, and the fourth switch are MOSFETs or IGBTs. A MOSFET consists of a source, a drain, and a gate, while an IGBT is a semiconductor switching element that combines the advantages of MOSFETs and BJTs (bipolar junction transistors).

[0085] In one embodiment, the control circuitry is housed in the control device 12.

[0086] Please see Figure 2 , Figure 2 This is a flowchart illustrating a temperature control method provided in an embodiment of this application. This application provides the operational steps of the method described in the embodiments or flowchart, but based on conventional or non-inventive methods, more or fewer operational steps may be included. The order of steps listed in the embodiments is merely one possible execution order among many and does not represent the only possible execution order. In actual system or server product execution, the methods can be executed sequentially according to the embodiments or drawings, or in parallel (e.g., in a parallel processor or multi-threaded processing environment). Figure 2 As shown, the temperature control method provided in this application embodiment can be applied to, for example... Figure 1 The water purification equipment shown may specifically include the following steps:

[0087] S201, acquire the first temperature detected by the first temperature sensor, the second temperature detected by the second temperature sensor, the first humidity detected by the first humidity sensor, and the second humidity detected by the second humidity sensor.

[0088] Specifically, a first temperature sensor is used to acquire a first temperature T1 of the first chamber, and a control device is used to receive the first temperature T1; a second temperature sensor is used to acquire a second temperature T2 of the second chamber, and a control device is used to receive the second temperature T2; a first humidity sensor is used to acquire a first humidity H1 of the first chamber, and a control device is used to receive the first humidity H1; a second humidity sensor is used to acquire a second humidity H2 of the second chamber, and a control device is used to receive the second humidity H2.

[0089] S203, when the first temperature detected by the first temperature sensor, the second temperature detected by the second temperature sensor, the first humidity detected by the first humidity sensor, and the second humidity detected by the second humidity sensor meet the first environmental conditions, the temperature regulating device is controlled to alternately heat one of the first chamber and the second chamber and cool the other, so as to generate a temperature gradient between the first chamber and the second chamber.

[0090] By alternating heating and cooling of the first and second chambers, more precise and rapid temperature regulation can be achieved, reducing the possibility of insect infestation in the water purification equipment without the addition of pesticides, and helping to reduce water accumulation.

[0091] Specifically, the control device is used to control the conduction state of each switch in the control circuit so that the current direction is either the first direction or the second direction. The control device is used to determine whether the first temperature T1, the second temperature T2, the first temperature H1, and the second temperature H2 meet the first preset temperature condition and obtain a first comparison result. If the first comparison result indicates that the first temperature T1, the second temperature T2, the first temperature H1, and the second temperature H2 meet the first preset temperature condition, the device alternately increases one of the first temperature and the second temperature while decreasing the other. If the first comparison result indicates that the first temperature T1, the second temperature T2, the first temperature H1, and the second temperature H2 do not meet the first preset temperature condition, the temperature regulating device operates without load.

[0092] In one embodiment, if the first comparison result indicates that the first temperature T1, the second temperature T2, the first temperature H1, and the second temperature H2 meet a first preset temperature condition, the alternating execution of raising one of the first temperature T1 and the second temperature T2 and lowering the other includes: setting the current direction of the control circuit to the first direction, raising the first temperature T1 and lowering the second temperature T2 for a first preset time period; then setting the current direction of the control circuit to the second direction, raising the second temperature T2 and lowering the first temperature T1 for a second preset time period, and repeating the execution until the number of switching directions of the control circuit is greater than or equal to the preset number of switching directions.

[0093] In another embodiment, if the first comparison result indicates that the first temperature T1, the second temperature T2, the first temperature H1, and the second temperature H2 meet a first preset temperature condition, the alternating execution of raising one of the first temperature T1 and the second temperature T2 and lowering the other includes: controlling the current direction of the control circuit to be a first direction, raising the first temperature T1 and lowering the second temperature T2 for a first preset time period; then controlling the current direction of the control circuit to be a second direction, raising the second temperature T2 and lowering the first temperature T1 for a second preset time period, until the first humidity H1 and the second humidity H2 meet a second environmental condition, the second environmental condition indicating that the first humidity H1 and the second humidity H2 are less than or equal to a preset humidity threshold.

[0094] In one embodiment, such as Figure 3 As shown, step S203 further includes:

[0095] S301, control the current direction of the temperature regulating device to the first direction, so as to raise the first temperature and lower the second temperature at the same time.

[0096] Specifically, the control device opens the first and third switches and closes the second and fourth switches. At this time, the current direction of the control circuit is the first direction, the first surface is the heating surface to raise the first temperature T1, and the second surface is the cooling surface to lower the first temperature T2.

[0097] For example, when the first temperature T1 and the second temperature T2 are both 25°C, the first switch and the third switch are turned on and the second switch and the fourth switch are turned off. The first side heats up for 10 minutes and the second side cools down for 10 minutes. At this time, the first temperature T1 rises to 40°C and the second temperature T2 drops to 15°C.

[0098] S303, after a first preset time period, the current direction of the temperature regulating device is controlled to the second direction, so as to lower the first temperature and raise the second temperature at the same time.

[0099] Specifically, the control device opens the second and fourth switches and closes the first and third switches. At this time, the current direction of the control circuit is the second direction, the first side is the cooling side to lower the first temperature T1, and the second side is the heating side to raise the first temperature T2.

[0100] In one embodiment, such as Figure 4 As shown, step S303 further includes:

[0101] S401, after a first preset time period, obtain the real-time first temperature of the first chamber and the real-time second temperature of the second chamber to obtain the first temperature difference.

[0102] Specifically, the first preset time period is 5min-20min, that is, after one temperature adjustment, the real-time first temperature of the first chamber and the real-time second temperature of the second chamber are obtained to obtain the first temperature difference ΔT1, so as to determine whether the preset dehumidification effect has been achieved after one temperature adjustment.

[0103] S403, if the first temperature difference is less than the first temperature difference threshold, increase the current intensity of the temperature regulating device and adjust the current direction of the temperature regulating device to the second direction, so as to lower the first temperature and raise the second temperature.

[0104] By acquiring the temperatures of the first and second chambers in real time, it is possible to accurately grasp the temperature change trends and current temperature differences between the first and second chambers, thereby enabling rapid temperature regulation of each chamber and helping to maintain and optimize the temperature gradient between the chambers.

[0105] Specifically, a first temperature difference ΔT1 is compared with a first temperature difference threshold to obtain a second comparison result. If the second comparison result indicates that the first temperature difference ΔT1 is greater than the first temperature difference threshold, it indicates that the preset dehumidification effect has been achieved after one temperature adjustment. If the second comparison result indicates that the first temperature difference ΔT1 is less than the first temperature difference threshold, it indicates that the preset dehumidification effect has not been achieved after one temperature adjustment. The current intensity of the control circuit, the temperature shock time, or the operating power of each fan is then adjusted. In one embodiment, increasing the current intensity of the control circuit increases the temperature gradient between the first temperature T1 and the second temperature T2.

[0106] S305, repeatedly execute the control of the temperature regulating device to the first direction to raise the first temperature and lower the second temperature, and after a first preset time period, control the temperature regulating device to the second direction to lower the first temperature and raise the second temperature until the target switching current number is greater than or equal to the preset switching current number.

[0107] Specifically, steps S301 and S305 are repeated. Before switching the current direction of the control circuit, the target switching current count is set to zero. Each time the current direction of the control circuit is switched, the target switching current count is incremented by one until the target switching current count is greater than or equal to the preset switching current count.

[0108] By alternating the direction of the current to regulate the temperature of the first and second chambers, precise temperature management is achieved, improving the efficiency of temperature shock, reducing the continuous high-load operation of the temperature regulation device, and reducing the accumulation of moisture inside the equipment.

[0109] In another embodiment, step S203 includes:

[0110] S501, the current direction of the temperature regulating device is controlled to be the first direction, so as to raise the first temperature and lower the second temperature.

[0111] S503, after a first preset time period, obtain the real-time first temperature of the first chamber and the real-time second temperature of the second chamber to obtain the first temperature difference.

[0112] S505, if the first temperature difference ΔT1 is less than the first temperature difference threshold, adjust the current direction of the temperature regulating device to the second direction to lower the first temperature T1 and raise the second temperature T2.

[0113] S507, after a second preset time period, the current direction of the temperature regulating device is adjusted to the first direction to raise the first temperature T1 and lower the second temperature T2, wherein the second preset time period is longer than the first preset time period.

[0114] By adjusting the alternating heating and cooling time of the first and second chambers, the dehumidification and insect repellent efficiency is improved, avoiding excessively high or low temperatures in any one chamber, thus enhancing the dehumidification and insect repellent effects and extending the service life of the water purification equipment.

[0115] Specifically, the control device opens the first and third switches and closes the second and fourth switches. At this time, the current direction of the control circuit is the first direction, the first surface is the heating surface to raise the first temperature T1, and the second surface is the cooling surface to lower the first temperature T2. After a first preset time period, the real-time first temperature of the first chamber and the real-time second temperature of the second chamber are obtained to obtain the first temperature difference ΔT1, so as to determine whether the preset dehumidification effect has been achieved after one temperature adjustment. The first temperature difference ΔT1 is compared with the first temperature difference threshold to obtain the second comparison result. If the second comparison result indicates that the first temperature difference ΔT1 is greater than the first temperature difference threshold, it indicates that the preset dehumidification effect has been achieved after one temperature adjustment. If the second comparison result indicates that the first temperature difference ΔT1 is less than the first temperature difference threshold, it indicates that the preset dehumidification effect has not been achieved after one temperature adjustment. To increase the temperature shock time, the control device opens the second and fourth switches and closes the first and third switches. At this time, the current direction of the control circuit is the second direction, the first surface is the cooling surface to lower the first temperature T1, and the second surface is the heating surface to raise the first temperature T2.

[0116] For example, the control device opens the first switch and the third switch and closes the second switch and the fourth switch. At this time, the current direction of the control circuit is the first direction, the first surface is the heating surface to raise the first temperature T1, and the second surface is the cooling surface to lower the first temperature T2. This continues for 10 minutes. The real-time first temperature of the first chamber and the real-time second temperature of the second chamber are obtained to obtain the first temperature difference ΔT1. The first temperature difference ΔT1 is compared with the first temperature difference threshold to obtain the second comparison result. If the second comparison result indicates that the first temperature difference ΔT1 is less than the first temperature difference threshold, this continues for 15 minutes, and then the current direction of the control circuit is adjusted again.

[0117] For example, the control device turns on the first and third switches and turns off the second and fourth switches. At this time, the current direction of the control circuit is the first direction, the first surface is the heating surface to raise the first temperature T1, and the second surface is the cooling surface to lower the first temperature T2. This continues for 10 minutes. The real-time first temperature of the first chamber and the real-time second temperature of the second chamber are obtained to obtain the first temperature difference ΔT1. The first temperature difference ΔT1 is compared with the first temperature difference threshold to obtain the second comparison result. If the second comparison result indicates that the first temperature difference ΔT1 is less than the first temperature difference threshold, the speed of the first fan and the second fan is increased, and the current direction of the control circuit is adjusted again.

[0118] Specifically, during the temperature shock process, the first heat sink, the first fan, the second heat sink, and the second fan are continuously turned on. When the semiconductor cooling chip is the cooling surface, the corresponding temperature of the chamber facing the cooling surface is 5℃-20℃. When the semiconductor cooling chip is the heating surface, the corresponding temperature of the chamber facing the heating surface is 40℃-60℃.

[0119] Specifically, when the first temperature T1 and / or the second temperature T2 are lower than the warning temperature, in order to prevent condensate from accumulating in the first inner cavity and / or the second inner cavity of the water purification equipment, the fan in the cavity corresponding to the first temperature T1 and / or the second temperature T2 being lower than the warning temperature is turned off.

[0120] The following describes the specific process of the temperature control method in a particular embodiment.

[0121] S1, acquire the first temperature T1, the first humidity H1, the second temperature T2, and the second humidity H2;

[0122] S2, determine whether the first temperature T1 or the first temperature T2 is between 20℃ and 30℃ and whether the first humidity H1 and the second humidity H2 are greater than or equal to 70%;

[0123] If S3 is correct, jump to S4 and activate the temperature shock mode; otherwise, the control circuit is in a no-load state.

[0124] S4, turn on the first switch and the third switch of the control circuit, and simultaneously turn on the first heat sink, the first fan, the second heat sink and the second fan. The current direction is the first direction. The first side of the semiconductor cooling surface is the heating surface to raise the first temperature T1 and the second side of the semiconductor cooling surface is the cooling surface to lower the first temperature T2.

[0125] S5. After 10 minutes, turn on the second and fourth switches of the control circuit. The current direction is the second direction. The first side of the semiconductor cooling surface is the cooling surface to reduce the first temperature T1, and the second side of the semiconductor cooling surface is the heating surface to increase the first temperature T2.

[0126] S6, after 10 minutes, repeat S3 and S4 twice;

[0127] S7, the control circuit is in a no-load state, and the first heat sink, the first fan, the second heat sink and the second fan are turned off.
