Description

Technical Field

[0001] The present application relates to but is not limited to the field of inverter technology, and specifically refers to a heat dissipation device, an inverter, and a control method and a control device thereof. Background Art

[0002] At present, the inverter generates a lot of heat during operation. Therefore, the inverter is generally equipped with a heat dissipation device. Most of the heat dissipation devices use two heat dissipation methods: natural heat dissipation or air cooling, and the heat dissipation efficiency is low. Summary of the invention

[0003] The technical problem to be solved by the present application is to provide a heat dissipation device, an inverter and a control method and a control device thereof, which can improve the heat dissipation efficiency of the inverter and integrate a humidification function, and the humidification function has a disinfection and sterilization effect.

[0004] An embodiment of the present application provides a heat dissipation device for an inverter, the heat dissipation device comprising: a radiator, the radiator being provided with a heat dissipation channel; and a humidifier, comprising at least one water tank, at least one of the water tanks being provided with a humidification module, and at least one of the water tanks being configured to be connected to the heat dissipation channel to form a circulation loop so that part of the heat of the radiator can be transferred to the water in the humidifier.

[0005] In this way, when the inverter needs to dissipate heat, the water tank of the humidifier can be connected to the heat dissipation channel of the radiator to form a circulation loop, so that the water in the water tank can circulate between the radiator and the humidifier. On the one hand, it takes away the heat of the radiator and plays a role in dissipating heat and cooling the radiator. On the other hand, it realizes the transfer of part of the heat of the radiator to the water, so that the water temperature in the water tank gradually increases.

[0006] In addition, since the inverter generates a lot of heat when it is working, the water in the humidifier can be heated to high temperature water, for example, up to 100°C. High temperature water can effectively disinfect bacteria, viruses and other microorganisms, so the humidifier can use high temperature sterilized water for humidification, which can achieve a good disinfection and sterilization effect while playing a humidification role.

[0007] In the related art, humidifiers with antibacterial functions generally have their own purification systems. Purification systems generally come in two forms: one is to purify solid or gaseous pollutants through a filter, which is passive purification; the other is to have a built-in negative ion or plasma generator, which uses ions to absorb air bacteria to achieve active purification. Both methods are antibacterial, but the effect is not ideal.

[0008] This solution can disinfect and sterilize water through high temperature, with better disinfection and sterilization effects, and it is clean and pollution-free. Moreover, high temperature does not require additional power consumption, but utilizes the waste heat of the inverter, thus improving energy utilization efficiency and achieving the goal of green energy conservation.

[0009] In addition, the humidifier is located near the radiator, and the temperature of the radiator and its surrounding area is relatively high. Therefore, the water mist released by the humidifier is easily evaporated quickly in the high-temperature environment, thereby improving the humidification speed and quality, and can quickly increase the air humidity; and the water mist can also achieve disinfection and sterilization in the high-temperature environment, so the humidified air is cleaner and pollution-free.

[0010] The embodiment of the present application also provides an inverter, including the heat dissipation device described in any one of the above embodiments.

[0011] The embodiment of the present application also provides a control method for the inverter described in the above embodiment, and the control method includes:

[0012] Obtain the operating condition parameters of the inverter;

[0013] Control the heat dissipation device according to the operating condition parameters.

[0014] The embodiment of the present application also provides a control device, including a processor and a memory storing a computer program. When the processor executes the computer program, the steps of the control method described in any one of the above embodiments are implemented. Description of the Drawings

[0027] The principles and features of the present application will be described below with reference to the accompanying drawings. The examples given are only used to explain the present application and are not intended to limit the scope of the present application.

[0028] As Figures 1 to 5 shown, an embodiment of the present application provides a heat dissipation device for an inverter. The heat dissipation device includes: a heat sink 1 and a humidifier 2. The heat sink 1 can be connected to a heat-generating structure (such as a high-heat-generating electronic component) inside the inverter, so that the heat generated by the heat-generating structure can be dissipated outward in time through the heat sink 1.

[0029] Among them, as Figure 1 and Figure 2 shown, the heat sink 1 is provided with a heat dissipation flow path. The heat dissipation flow path can be a serpentine flow path, which is beneficial to improving the heat dissipation efficiency.

[0030] As Figure 1 and Figure 2 shown, the humidifier 2 includes at least one water tank. At least one water tank is provided with a humidification module 23. At least one water tank is arranged to be able to communicate with the heat dissipation flow path to form a circulation loop, so that part of the heat of the heat sink 1 can be transferred to the water in the humidifier 2. The water tank can be one, or two, three or more. The humidification module 23 can be one, or two, three or more. When the number of water tanks is multiple, only one water tank can form a circulation loop with the heat dissipation flow path, or two, three or more water tanks can form a circulation loop with the heat dissipation flow path. A power component such as a water pump 25 can be provided on the circulation loop to ensure that water can flow in the circulation loop and make the circulation loop conductive.

[0031] In this way, when the inverter needs to dissipate heat, the water tank of the humidifier 2 can be connected to the heat dissipation channel of the radiator 1 to form a circulation loop, so that the water in the water tank can circulate between the radiator 1 and the humidifier 2. On the one hand, it takes away the heat of the radiator 1 and plays a role in dissipating heat and cooling the radiator 1. On the other hand, it realizes the transfer of part of the heat of the radiator 1 to the water, so that the water temperature in the water tank gradually increases.

[0032] In addition, since the inverter generates a lot of heat when it is working, the water in the humidifier 2 can be heated to become high-temperature water, for example, up to 100° C. High-temperature water can effectively disinfect bacteria, viruses and other microorganisms, so the humidifier 2 can use high-temperature sterilized water for humidification, while playing a humidification role, it also achieves a good disinfection and sterilization effect.

[0033] The humidifier 2 with antibacterial function in the related art generally has its own purification system. There are generally two forms of purification systems: one is to purify solid or gaseous pollutants through a filter, which is passive purification; the other is to have a built-in negative ion or plasma generator, which uses ions to absorb air bacteria to achieve active purification. Both methods are antibacterial, and the effect is not ideal.

[0034] This solution can sterilize water through high temperature, which has better sterilization effect and is clean and pollution-free. In addition, high temperature does not require additional power consumption, but is achieved by using the waste heat of the inverter, thus improving energy utilization and achieving the goal of green energy saving.

[0035] In addition, the humidifier 2 is located near the radiator 1, and the temperature of the radiator 1 and its surrounding area is relatively high. Therefore, the water mist released by the humidifier 2 can easily evaporate quickly in a high temperature environment, thereby improving the speed and quality of humidification and quickly increasing the air humidity; and the water mist can also achieve disinfection and sterilization in a high temperature environment, so the humidified air is cleaner and pollution-free.

[0036] In some exemplary embodiments, at least one water tank is provided with an openable and closable water inlet 213 and an openable and closable water outlet 214, such as Figure 2 As shown. The water inlet 213 is configured to communicate with an external water source to supply water to the water tank. The water outlet 214 is configured to discharge the water in the water tank. The external water source may be, but is not limited to, tap water. The water inlet 213 may be connected to a water inlet pipe 215, and the water outlet 214 may be connected to a water outlet pipe 216, as shown. Figure 1 shown.

[0037] In this way, when the water temperature in the water tank is too high, resulting in low heat dissipation efficiency of the radiator 1, the water in the water tank can be discharged through the drain port, and then tap water can be replenished into the water tank through the water inlet 213 to reduce the temperature of the water flowing in the circulation loop, thereby improving the heat dissipation efficiency of the radiator 1.

[0038] Of course, in other cases, the water tank may also have a drainage requirement or a water replenishment requirement. For example: when the radiator 1 does not need heat dissipation and the humidifier 2 is short of water during the humidification process, water can also be replenished into the water tank through the water inlet 213. Or, when the water in the water tank has not flowed for a long time, it can also be drained through the drain port and then replenished through the water inlet 213.

[0039] In some exemplary embodiments, at least one water tank includes a first water tank 21 and a second water tank 22, as Figure 1 and Figure 2 shown. Of course, it may also include a third water tank, a fourth water tank, etc. The first water tank 21 is arranged to be able to communicate with the heat dissipation flow path to form a circulation loop. The first water tank 21 is provided with a water inlet 213 and a water outlet 214. The second water tank 22 is connected to the first water tank 21 through a switchable drainage flow path 24, as Figure 1 and Figure 2 shown. The drainage flow path 24 is arranged to convey the water in the first water tank 21 into the second water tank 22. A control valve may be provided on the drainage flow path 24 to control the on / off of the drainage flow path 24. The drainage flow path 24 may be an additionally provided pipeline, or may be formed by the butt joint of the joints of the first water tank 21 and the second water tank 22, or may be formed by the internal channel of the control valve. The volumes of the first water tank 21 and the second water tank 22 may be the same or different.

[0040] Among them, the second water tank 22 is a heat preservation water tank, and the second water tank 22 is provided with a humidification module 23, as Figure 1 shown.

[0041] In this way, the first water tank 21 is mainly used to communicate with the heat dissipation flow path to form a circulation loop, dissipate heat from the radiator 1 through water, and absorb the heat of the radiator 1 to increase the water temperature to provide high-temperature water. The high-temperature water can be conveyed into the second water tank 22 through the drainage flow path 24 for storage. The second water tank 22 is mainly used to store high-temperature water for humidification. Since the second water tank 22 is a heat preservation water tank, the heat loss is small, which is beneficial to ensuring that the water for humidification is always high-temperature water after disinfection and sterilization.

[0042] In some exemplary embodiments, the first water tank 21 is also provided with a humidification module 23, as Figure 1 shown.

[0043] In this way, when the water in the second water tank 22 is used up, the first water tank 21 can also continue to implement the humidification function through the humidification module 23.

[0044] In some exemplary embodiments, the humidification module 23 includes an atomization module. The atomization module includes an atomization cover 231, an atomization sheet 232, and a water absorption member 233, as Figure 3 and Figure 4 shown. The water tank provided with the humidification module 23 is provided with an installation opening 212, as Figure 4 shown. One end of the water absorption member 233 is located inside the water tank, and the other end of the water absorption member 233 is located at the installation opening 212, and is configured to conduct the water in the water tank to the atomization sheet 232. The atomization sheet 232 is disposed at the installation opening 212 and is configured to atomize the water. The atomization cover 231 is fixed to the water tank, fixes the atomization sheet 232 at the installation opening 212, and the atomization cover 231 is provided with an air outlet 2313 corresponding to the installation opening 212.

[0045] Among them, the water absorption member 233 can be components such as cotton swabs, sponges, and wet curtains. The atomization cover 231 can be fixed to the water tank by means of fasteners (such as screws), and the atomization sheet 232 is clamped between the atomization cover 231 and the water tank to achieve fixation.

[0046] Of course, the humidification module 23 is not limited to the atomization module.

[0047] In some exemplary embodiments, as Figure 4 shown, the atomization cover 231 includes a cover body 2311 and an extension plate 2312 connected to the cover body 2311. The cover body 2311 is provided with an air outlet 2313 and presses the atomization sheet 232. A wire outlet channel 217 is formed between the extension plate 2312 and the water tank. The radiator 1 is provided with a wire outlet hole communicating with the wire outlet channel 217. The connecting wire 2321 of the atomization sheet 232 passes through the wire outlet channel 217 and the wire outlet hole.

[0048] In this way, the connecting wire 2321 of the atomization sheet 232 can enter the inverter through the wire outlet channel 217 and the wire outlet hole and be connected to the electronic control board of the inverter to be powered on, and the connecting wire 2321 is prevented from being exposed.

[0049] In one example, as Figure 4 shown, the upper end of the water tank can be partially recessed to form an installation groove, and the installation opening 212 is arranged on the bottom wall of the installation groove. The atomization sheet 232 is placed in the installation groove, and the upper end is flush with the upper end surface of the water tank. The cover body 2311 presses the upper end surface of the water tank and the atomization sheet 232, and is fixedly connected to the water tank by a circle of screws. Moreover, the atomization cover 231 covers the installation groove to ensure the integrity of the appearance of the water tank. The installation groove extends away from the atomization sheet 232 to the radiator 1. The wire outlet channel 217 is the space surrounded by the extension plate 2312 of the atomization cover 231 and the installation groove. The part of the radiator 1 corresponding to the wire outlet channel 217 is provided with a wire outlet hole to ensure that the connecting wire 2321 in the wire outlet channel 217 can extend into the inverter through the wire outlet hole without being exposed.

[0050] In some exemplary embodiments, as Figure 1 and Figure 2 shown, the radiator 1 includes a heat dissipation base 11, heat dissipation fins 12 provided on the heat dissipation base 11, and a heat dissipation pipe 13 passing through the heat dissipation fins 12. The internal space of the heat dissipation pipe 13 forms a heat dissipation flow channel. The heat dissipation fins 12 can be arranged corresponding to the high heat generation area of the inverter to improve the heat dissipation efficiency of the high heat generation area. The heat dissipation base 11, the heat dissipation fins 12, and the heat dissipation pipe 13 can all be made of materials with good thermal conductivity, such as aluminum, copper, etc.

[0051] The water tank is fixed to the heat dissipation base 11 and is located below the heat dissipation fins 12. The humidifier 2 is provided with an air outlet 2313, and the air outlet 2313 faces the heat dissipation fins 12. The water tank can be fixed to the heat dissipation base 11 by means of fasteners (such as screws), etc.

[0052] In this way, the humidifier 2 releases water mist upward through the air outlet 2313. The water mist will contact the heat dissipation fins 12, evaporate efficiently, and be sterilized by high temperature. Fixing the water tank on the heat dissipation base 11 is beneficial to reducing the volume of the heat dissipation device, saving space, and is also beneficial to reducing the distance between the water tank and the heat dissipation flow channel, which is beneficial to simplifying the pipeline layout.

[0053] Among them, the heat dissipation fins 12 can extend in the vertical direction and a plurality of them are arranged side by side. This is beneficial to both improving the heat dissipation efficiency and facilitating the upward flow of the water mist released by the humidifier 2.

[0054] In some embodiments, the heat dissipation device further includes an inductor box 14, as Figure 1 shown, the inductor box 14 is located below the humidifier 2. Each water tank can be provided with a temperature sensor 31 for detecting the water temperature in the water tank. A temperature sensor 31 can be arranged at the heat dissipation fins 12 for detecting the temperature of the radiator 1. A humidity sensor 32 can be arranged on the inductor box 14 for detecting the ambient humidity. Of course, the temperature sensor 31 and the humidity sensor 32 can also be arranged at other positions.

[0055] The embodiment of the present application also provides an inverter (not shown in the figure), including the heat dissipation device as described in any one of the above embodiments, and thus has all the above beneficial effects, which will not be elaborated here.

[0056] The embodiment of the present application also provides a control method for the inverter as described in the above embodiments. As Figure 6 shown, the control method includes:

[0057] Step S202: Obtain the operating condition parameters of the inverter;

[0058] Step S204: Control the heat dissipation device according to the operating condition parameters.

[0059] The control method provided by the embodiments of the present application can obtain the operating condition parameters of the inverter, and then control the heat dissipation device according to the operating condition parameters to meet the heat dissipation requirements of the inverter, and can be used to humidify the environment, and the humidified air is cleaner and pollution-free.

[0060] In some exemplary embodiments, the operating condition parameters include the temperature of radiator 1. The temperature of radiator 1 can be obtained by the temperature sensor 31 disposed at the heat dissipation fins 12 of radiator 1. Of course, the position and quantity of the temperature sensor 31 can be adjusted according to needs.

[0061] Controlling the heat dissipation device according to the operating condition parameters includes:

[0062] Based on the temperature of radiator 1 exceeding the first set temperature threshold, controlling the circulation loop to conduct to dissipate heat from radiator 1.

[0063] When the temperature of radiator 1 exceeds the first set temperature threshold, it indicates that the temperature of radiator 1 is on the high side and heat dissipation is required. Therefore, controlling the circulation loop to conduct enables the water in the water tank to enter the heat dissipation flow channel to absorb the heat of radiator 1, realizing efficient heat dissipation of radiator 1.

[0064] In one example, controlling the circulation loop to conduct includes: controlling the water tank to communicate with the heat dissipation flow channel and starting the water pump 25 on the heat dissipation flow channel. The first set temperature threshold can be the optimal operating temperature T0 of the inverter.

[0065] In some exemplary embodiments, the operating condition parameters further include the water temperature and water volume in the water tank in the circulation loop.

[0066] Controlling the heat dissipation device according to the operating condition parameters further includes:

[0067] Based on the water temperature in the water tank in the circulation loop rising to within the set water temperature range and the water volume being full, and the temperature of radiator 1 not being less than or equal to the second set temperature threshold (i.e., greater than the second set temperature threshold), discharging the water in the water tank in the circulation loop;

[0068] Based on the water in the water tank in the circulation loop being discharged completely, opening the water inlet 213 of the water tank to supply water to the water tank.

[0069] Wherein, the second set temperature threshold is less than or equal to the first set temperature threshold. The second set temperature threshold can be the optimal operating temperature T0 of the inverter. The water volume can be characterized by parameters such as water level, volume, weight, etc. Correspondingly, detection devices such as water level sensors and weight sensors can be set to obtain the water volume of the corresponding water tank. According to the water level and the shape of the corresponding water tank, the volume of water can be calculated. The set water temperature range can be, but is not limited to, the boiling point of water (such as 100 °C) or a temperature range close to the boiling point of water, such as 90 °C to 100 °C.

[0070] When the water temperature in the water tank in the circulation loop rises to within the set water temperature range, it indicates that the water has become high-temperature water, and the heat dissipation efficiency of the radiator 1 will be relatively low; while the temperature of the radiator 1 has not dropped below the second set temperature threshold, indicating that the temperature of the radiator 1 has not dropped to the required temperature and continues to dissipate heat. Also, the water tank is full of water, indicating that there is excess high-temperature water. Therefore, the high-temperature water in the water tank is drained out. After draining is completed, the water inlet 213 is opened to replenish low-temperature water into the water tank, and then the low-temperature water is used to continue dissipating heat from the radiator 1. This process is repeated until the temperature of the radiator 1 drops to less than or equal to the second set temperature threshold, and the circulation loop is disconnected.

[0071] In some exemplary embodiments, the water tank in the circulation loop is the first water tank 21, and the humidifier 2 further includes a second water tank 22 communicated with the water tank through a drainage flow path 24. The operating parameters further include the water volume in the second water tank 22. The second water tank 22 is a heat-insulated water tank. A control valve can be provided in the drainage flow path 24 to control the on-off of the drainage flow path 24.

[0072] Draining the water in the water tank in the circulation loop includes:

[0073] Based on the fact that the water volume in the second water tank 22 is not full, the drainage flow path 24 is conducted to drain the water in the first water tank 21 into the second water tank 22 until the second water tank 22 is full or the first water tank 21 is emptied;

[0074] Based on the fact that the water volume in the second water tank 22 is full, the water outlet 214 of the first water tank 21 is opened to drain the water in the first water tank 21 through the water outlet 214.

[0075] When the first water tank 21 needs to be drained, if the water volume in the second water tank 22 is not full, it indicates that only the high-temperature water in the first water tank 21 is in excess, while the high-temperature water in the second water tank 22 is not in excess. Therefore, the drainage flow path 24 is preferentially conducted to drain the high-temperature water in the first water tank 21 into the second water tank 22 until the second water tank 22 is full or the first water tank 21 is emptied, so as to make full use of the high-temperature water for humidification. During the process of the first water tank 21 draining water to the second water tank 22, if the second water tank 22 is full but the first water tank 21 has not been emptied, the drainage flow path 24 is closed, and the water outlet 214 of the first water tank 21 is opened to drain the remaining high-temperature water in the first water tank 21 to the outside. During the process of the first water tank 21 draining water to the second water tank 22, if the first water tank 21 is emptied but the second water tank 22 is not full (for example, the second water tank 22 has been continuously consuming high-temperature water during the humidification process), the drainage flow path 24 is closed. When the water in the first water tank 21 is emptied, the water inlet 213 of the first water tank 21 is opened to replenish water into the first water tank 21 until it is full.

[0076] When the first water tank 21 needs to drain water, if the water volume in the second water tank 22 is full, it indicates that the high-temperature water in both the first water tank 21 and the second water tank 22 is excessive. Therefore, open the water outlet 214 of the first water tank 21 and directly drain the water in the first water tank 21 to the outside. When the water in the first water tank 21 is emptied, open the water inlet 213 of the first water tank 21 to replenish water to the first water tank 21 until it is full.

[0077] In some exemplary embodiments, the operating condition parameters further include the humidity of the environment. The environment can be an indoor space.

[0078] Controlling the heat dissipation device according to the operating condition parameters further includes:

[0079] Based on the humidity of the environment being lower than the first set humidity threshold, start the humidification module 23.

[0080] When the humidity of the environment is lower than the first set humidity threshold, it indicates that the ambient air is relatively dry and needs to be humidified. Therefore, start the humidification module 23 to humidify the ambient air.

[0081] In some exemplary embodiments, the humidifier 2 includes a first water tank 21 and a second water tank 22 connected to the first water tank 21 through a drainage flow path 24, and humidification modules 23 are provided in both the first water tank 21 and the second water tank 22. The operating condition parameters further include: the water volume in the first water tank 21 and the water volume in the second water tank 22. The second water tank 22 is a heat-insulated water tank.

[0082] Based on the humidity of the environment being lower than the first set humidity threshold, starting the humidification module 23 includes:

[0083] Based on the humidity of the environment being lower than the first set humidity threshold and there being water in the second water tank 22, start the humidification module 23 of the second water tank 22;

[0084] Based on the water in the second water tank 22 being exhausted and the humidity of the environment being less than the second set humidity threshold, then start the humidification module 23 of the first water tank 21.

[0085] Wherein, the second set humidity threshold is greater than or equal to the first set humidity threshold;

[0086] Controlling the heat dissipation device according to the operating condition parameters further includes:

[0087] Based on the water in the first water tank 21 being exhausted, open the water inlet 213 of the first water tank 21 to supply water to the first water tank 21.

[0088] In other words, when the environment requires humidification treatment, if there is water in the second water tank 22, the humidification module 23 of the second water tank 22 is activated, and the high-temperature water in the second water tank 22 is preferentially used for humidification. If the high-temperature water in the second water tank 22 is exhausted, it indicates that there is no excess high-temperature water in the first water tank 21, and the environmental humidity still does not reach the required humidity (i.e., it is not greater than or equal to the second set humidity threshold). Therefore, the first water tank 21 is switched to for humidification, the humidification module 23 of the first water tank 21 is activated, and the humidification treatment is continued.

[0089] When the water in the first water tank 21 is exhausted, the water inlet 213 of the first water tank 21 is opened for water replenishment.

[0090] In some exemplary embodiments, controlling the heat dissipation device according to the working condition parameters further includes:

[0091] Based on the environmental humidity being greater than or equal to the second set humidity threshold, the humidification module 23 is turned off.

[0092] In the embodiments of the present application, when the water inlet 213 is opened to supply water / replenish water to the water tank, the water tank can be supplied with water / replenished until it is full. The water in the water tank is full, which means that the water in the water tank reaches the rated water volume, which can be that the water tank is completely full or almost full. The water in the water tank is exhausted / drained / emptied, which can be that the water in the water tank is completely emptied or almost emptied. There is water in the second water tank 22, which means that the water volume in the second water tank 22 can be used for humidification by the humidification module 23, for example, at least it can ensure that the water absorption member 233 sucks the water to the atomization sheet 232.

[0093] In one embodiment, the water circuit structure of the heat dissipation device is as Figure 7 shown, and the control logic principle is as Figure 8 shown. In Figure 7 and Figure 8 the first water tank 21 is denoted as water tank T1, and the second water tank 22 is denoted as water tank T2. The radiator 1 is denoted as radiator T3. The first set temperature threshold and the second set temperature threshold are equal, and can be the optimal operating temperature of the radiator, denoted as T0. The set temperature range of the water tank is 100 °C. The basic working principle is as follows:

[0094] 1) When the temperature sensor detects that the temperature of the inverter radiator T3 is greater than T0, the water pump is turned on, the B path is connected, and the water in the water tank T1 circulates to dissipate heat from the radiator.

[0095] 2) When both the water tank T1 and the water tank T2 are full of water and reach 100 degrees Celsius, it indicates that there is excess hot water in both the water tank T1 and the water tank T2. The C path is connected, and the water tank T1 will drain the hot water. After the hot water in the water tank T1 is emptied, the A path is connected, and tap water refills the water tank T1 with cold water, and the cycle of heat dissipation continues until the temperature of the radiator T3 is less than or equal to T0.

[0096] 3) When the water tank T1 reaches 100 degrees and is full of water, and the water tank T2 is not full of water, it indicates that there is excess hot water in the water tank T1. The D path is open, and the hot water is stored in the heat preservation water tank T2. After the hot water in the water tank T1 is emptied, the A path is open, and the tap water refills the water tank T1 with cold water again, and the cycle dissipates heat until the temperature of the radiator T3 is less than or equal to the optimal temperature T0.

[0097] 4) When the humidity sensor detects that the room needs humidification, the water tank T2 starts to humidify. When the water in the water tank T2 is empty, it indicates that there is no excess hot water in the water tank T1, and it switches to humidifying the water tank T1. When the water in the water tank T1 is empty, the A path is open, and the tap water automatically adds water.

[0098] This embodiment has the following advantages:

[0099] 1) The water in the water tank becomes high-temperature water through heat transfer by the radiator, which can disinfect and sterilize. At the same time, the small water droplets atomized and sprayed onto the radiator are also disinfected and sterilized by the high-temperature radiator. Compared with traditional humidifiers, the humidified air is cleaner and pollution-free.

[0100] 2) The small water droplets atomized and sprayed onto the radiator evaporate more quickly at high temperature, improving the humidification speed and quality, and can quickly increase the air humidity.

[0101] 3) The water tank is connected to the tap water pipe and can automatically add water.

[0102] 4) The water tank T2 has a heat preservation function and stores hot water, which can ensure that the water for humidification is always the water after high-temperature disinfection and sterilization.

[0103] 5) It can dissipate heat for the inverter while humidifying, and there is a set of intelligent algorithms to control the water circuit for heat dissipation.
