DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the embodiments of the present invention.

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] See Figures 1 to 3An embodiment of the present invention provides an induction evaporation device 100, which includes a low-temperature evaporator 12, a high-temperature evaporator 13, and an induction heating assembly 14. The high-temperature evaporator 13 is connected to the low-temperature evaporator 12. The induction heating assembly 14 includes a first induction heating element 141 and a second induction heating element 142. The first induction heating element 141 is disposed around the periphery of the low-temperature evaporator 12 and is suitable for heating the liquid in the low-temperature evaporator 12. The second induction heating element 142 is disposed around the periphery of the high-temperature evaporator 13. The heating power of the second induction heating element 142 is greater than the heating power of the first induction heating element 141. The second induction heating element 142 is suitable for heating ordinary steam entering the high-temperature evaporator 13 from the low-temperature evaporator 12. The first induction heating element 141 and the second induction heating element 142 can be electromagnetic induction coils, and can be specifically configured according to actual conditions.

[0032] When an electromagnetic induction coil is energized, a changing magnetic field is generated around it. This changing magnetic field induces currents in the conductor, known as eddy currents. When a device is placed in this changing magnetic field, eddy currents are generated within the device. These eddy currents hinder electrons within the device, creating resistance and converting electrical energy into heat.

[0033] In this way, it is helpful to achieve the separation of liquid and steam, and to reduce the mutual interference of heat between liquid and steam, so that the first induction heating element 141 can specifically heat the liquid in the low-temperature evaporation element 12 to generate ordinary steam, thereby improving the heating efficiency of the first induction heating element 141, and also enables the second induction heating element 142 to specifically heat the ordinary steam in the high-temperature evaporation element 13 to generate high-temperature steam, thereby improving the heating efficiency of the second induction heating element 142, thereby improving the efficiency of the induction evaporation device 100 in generating high-temperature steam.

[0034] In addition, the first induction heating element 141 is arranged around the periphery of the low-temperature evaporator 12, and the second induction heating element 142 is arranged around the periphery of the high-temperature evaporator 13, which helps to increase the induction area of ​​the first induction heating element 141 and the second induction heating element 142, thereby increasing the heat generation of the first induction heating element 141 and the second induction heating element 142, and also helps to improve the uniformity of heating of the low-temperature evaporator 12 and the high-temperature evaporator 13, avoiding local overheating or insufficient heating, and helping to reduce heat loss caused by heat concentration in a certain area. It also helps to improve the heating efficiency of the first induction heating element 141 and the second induction heating element 142, thereby improving the efficiency of the induction evaporation device 100 in generating high-temperature steam.

[0035] Among them, ordinary steam refers to steam with a temperature of 55℃~100℃, for example, the temperature of ordinary steam can be 55℃, 65℃, 70℃, 78℃, 88℃, 95℃, 100℃ or other temperatures; high-temperature steam refers to steam with a temperature reaching 380℃, for example, the temperature of high-temperature steam can be 380℃, 385℃, 390℃, 398℃, 400℃ or other temperatures, and the specific settings can be made according to actual conditions.

[0036] The induction evaporation device 100 can generate ordinary steam and / or high-temperature steam according to actual needs, thereby enriching the functions of the induction evaporation device 100 and better adapting to usage needs in different scenarios.

[0037] In some embodiments, the number of turns of the first induction heating element 141 is smaller than the number of turns of the second induction heating element 142 .

[0038] The number of turns of the induction heating element affects the magnetic field strength, which in turn affects the eddy current intensity and heat generation of the device. Because the eddy current intensity and heat generation required by the low-temperature evaporation element 12 are lower than those required by the high-temperature evaporation element 13, by adaptively setting the number of turns of the first induction heating element 141 to be smaller than the number of turns of the second induction heating element 142, the eddy current intensity and heat generation at the low-temperature evaporation element 12 can be smaller than the eddy current intensity and heat generation at the high-temperature evaporation element 13. This helps reduce energy consumption at the low-temperature evaporation element 12, thereby improving the energy efficiency of the induction evaporation device 100. It also helps increase the eddy current intensity and heat generation at the high-temperature evaporation element 13, thereby improving the efficiency of the high-temperature evaporation element 13 in generating high-temperature steam.

[0039] In some embodiments, the induction evaporation device 100 includes a first temperature sensor 15 and a second temperature sensor 16. The first temperature sensor 15 and the second temperature sensor 16 are installed on the low-temperature evaporator 12. The detection end of the first temperature sensor 15 is located on the bottom wall of the low-temperature evaporator 12. The detection end of the second temperature sensor 16 is higher than the detection end of the first temperature sensor 15. The first temperature sensor 15 is suitable for detecting a first temperature in the low-temperature evaporator 12, and the second temperature sensor 16 is suitable for detecting a second temperature in the low-temperature evaporator 12.

[0040] Because water is a good heat-conducting medium that can effectively absorb and transfer heat, when there is no water, heat accumulates around the detection end of the temperature sensor, causing the temperature detected by the detection end of the temperature sensor to rise and exceed the preset temperature. When water is present and the detection end of the temperature sensor is submerged in water, the temperature detected by the detection end of the temperature sensor remains at the preset temperature.

[0041] In this way, the first temperature sensor 15 can detect whether there is water in the low-temperature evaporator 12. The first temperature sensor 15 and the second temperature sensor 16 work together to determine the liquid level in the low-temperature evaporator 12 based on the detected temperature. When the low-temperature evaporator 12 is short of water, the low-temperature evaporator 12 is promptly replenished with water, ensuring that the low-temperature evaporator 12 has an appropriate liquid level condition. This ensures that the low-temperature evaporator 12 has an appropriate amount of water, thereby ensuring the normal operation of the low-temperature evaporator 12 and ensuring that the low-temperature evaporator 12 can produce standard steam that meets the requirements. This, in turn, ensures that the high-temperature evaporator 13 has standard steam that meets the requirements, thereby ensuring that the high-temperature evaporator 13 can produce high-temperature steam. The first temperature sensor 15 and the second temperature sensor 16 can integrate the functions of temperature detection and liquid level detection. The inductive evaporation device 100 does not need to include a separate liquid level sensor to detect the liquid level in the low-temperature evaporator 12, which helps simplify the structure of the inductive evaporation device 100 and facilitates manufacturing.

[0042] Exemplarily, when the first temperature sensor 15 detects that the first temperature in the low-temperature evaporator 12 is greater than or equal to the preset temperature of the first temperature sensor 15, it means that the water in the low-temperature evaporator 12 is not immersed in the detection end of the first temperature sensor 15. Since the detection end of the first temperature sensor 15 is located on the bottom wall of the low-temperature evaporator 12, there is no water in the low-temperature evaporator 12 at this time, and the low-temperature evaporator 12 needs to be replenished with water in time; when the first temperature sensor 15 detects that the first temperature in the low-temperature evaporator 12 is maintained at the preset temperature of the first temperature sensor 15, it means that the water in the low-temperature evaporator 12 is immersed in the detection end of the first temperature sensor 15. At this time, there is water in the low-temperature evaporator 12 and the water reaches the first liquid level.

[0043] For another example, when the difference between the second temperature in the low-temperature evaporator 12 detected by the second temperature sensor 16 and the first temperature in the low-temperature evaporator 12 detected by the first temperature sensor 15 is greater than or equal to the preset difference, it means that the water in the low-temperature evaporator 12 submerges the detection end of the first temperature sensor 15 but does not submerge the detection end of the second temperature sensor 16. At this time, the water in the low-temperature evaporator 12 has not reached the second liquid level, and the low-temperature evaporator 12 needs to be replenished with water according to actual conditions; when the second temperature in the low-temperature evaporator 12 detected by the second temperature sensor 16 is maintained at the preset temperature of the second temperature sensor 16, it means that the water in the low-temperature evaporator 12 submerges the detection end of the second temperature sensor 16, and at this time, the water in the low-temperature evaporator 12 reaches the second liquid level.

[0044] In this way, the coordinated cooperation of the first temperature sensor 15 and the second temperature sensor 16 helps the first temperature sensor 15 and the second temperature sensor 16 provide more comprehensive monitoring data, which helps to more accurately evaluate the temperature changes and liquid level environment in the low-temperature evaporator 12.

[0045] The detection end of the second temperature sensing element 16 may be disposed at a position 2 / 3 of the height of the low-temperature evaporation element 12 , and may be specifically disposed according to actual conditions.

[0046] The induction evaporation device 100 may be provided with a water inlet pipe connected to the top of the low-temperature evaporation element 12. When the first temperature sensor 15 and / or the second temperature sensor 16 detects that the low-temperature evaporation element 12 is empty or has insufficient water, water is promptly added to the low-temperature evaporation element 12 through the water inlet pipe.

[0047] The induction evaporation device 100 may be provided with a descaling pipe connected to the bottom of the low-temperature evaporation element 12. When there is residual water or dirt in the low-temperature evaporation element 12, it can be promptly discharged through the descaling pipe.

[0048] In some embodiments, the inductive evaporation device 100 includes a third temperature sensor 17 . The third temperature sensor 17 is mounted on the high-temperature evaporation element 13 and is suitable for detecting a third temperature in the high-temperature evaporation element 13 .

[0049] In this way, the third temperature sensor 17 can detect the steam temperature in the high-temperature evaporator 13 in real time, so that the steam in the high-temperature evaporator 13 can be in a suitable temperature environment, reducing the situation where the steam temperature in the high-temperature evaporator 13 is too low, and ensuring that the high-temperature evaporator 13 can produce high-temperature steam.

[0050] In which, the induction evaporation device 100 has a high-temperature steam preset temperature. When the third temperature reaches the high-temperature steam preset temperature, it means that the steam temperature in the high-temperature evaporation element 13 reaches the temperature requirement of the high-temperature steam; when the third temperature is lower than the high-temperature steam preset temperature, it means that the steam temperature in the high-temperature evaporation element 13 has not yet reached the temperature requirement of the high-temperature steam. At this time, the second induction heating element 142 can continue to work to further heat the steam in the high-temperature evaporation element 13 so that the steam temperature can reach the temperature requirement of the high-temperature steam.

[0051] The third temperature sensor 17 can be installed at the steam outlet of the high-temperature evaporator 13 to detect the steam temperature at the outlet in real time to ensure that the high-temperature evaporator 13 produces high-temperature steam that meets the temperature requirements.

[0052] See Figures 2 to 4 In some embodiments, the low-temperature evaporator 12 includes a shell 121 and a body guide 122. The shell 121 is provided with a liquid inlet 1211. The body guide 122 is installed on the shell 121. The body guide 122 is located at the liquid inlet 1211 and is spaced apart from the inner wall of the shell 121. The body guide 122 is inclined along the height direction Y of the low-temperature evaporator 12 from the liquid inlet 1211 toward the inner wall. The body guide 122 is suitable for guiding the liquid in the liquid inlet 1211 to the inner wall.

[0053] In this way, the body guide 122 can guide the liquid in the liquid inlet 1211 to the inner wall, and the liquid can directly contact the inner wall and quickly absorb the heat of the inner wall, thereby achieving rapid heating of the liquid, helping to improve the heating efficiency of the liquid, and also helping to achieve cooling of the inner wall, so that the water in the low-temperature evaporation element 12 reaches the boiling point faster, thereby accelerating the rate of ordinary steam generation, and helping to speed up the rate of ordinary steam entering the high-temperature evaporation element 13, thereby improving the efficiency of the induction evaporation device 100 in generating high-temperature steam.

[0054] In some embodiments, the liquid inlet 1211 is disposed at the top of the housing 121 , the guide body 122 is conical, and the vertex of the guide body 122 is connected to the liquid inlet 1211 to guide the liquid in the liquid inlet 1211 to the inner wall.

[0055] This helps to extend the heating path of the liquid. The liquid entering from the liquid inlet 1211 at the top of the shell 121 can flow downward to the bottom wall under the guidance of the guide body 122, so that the liquid can be fully heated to generate steam, increasing the amount of ordinary steam generated by the low-temperature evaporator 12, and then helping to increase the amount of ordinary steam entering the high-temperature evaporator 13, thereby improving the efficiency of the induction evaporation device 100 in generating high-temperature steam.

[0056] In some embodiments, the shell 121 is provided with a liquid chamber 1212 and a steam chamber 1213, the guide body 122 separates the liquid chamber 1212 and the steam chamber 1213, the guide body 122 is provided with a steam vent 1221, the steam vent 1221 connects the liquid chamber 1212 and the steam chamber 1213, the shell 121 is provided with a steam outlet 1214, the high-temperature evaporation element 13 is provided with a steam channel 131, and the steam outlet 1214 connects the steam chamber 1213 and the steam channel 131.

[0057] In this way, the ordinary steam generated after the liquid in the liquid chamber 1212 is heated and boiled can enter the steam chamber 1213 through the steam port 1221 and enter the steam channel 131 through the steam outlet 1214, thereby satisfying the flow of ordinary steam in the induction evaporation device 100, ensuring that ordinary steam can enter the high-temperature evaporation element 13, and reducing the situation where there is no steam in the high-temperature evaporation element 13 and damage caused by dry burning.

[0058] Among them, the outer side of the flow guide 122 is located in the steam chamber 1213, and the inner side of the flow guide 122 is located in the liquid chamber 1212. The liquid entering from the liquid inlet 1211 flows through the outer side of the flow guide 122 and flows to the inner wall. The amount of liquid on the outer side of the flow guide 122 will be less than the amount of liquid on the inner side of the flow guide 122. When a small amount of liquid on the outer side of the flow guide 122 contacts the inner wall, it can be quickly heated and boiled to generate steam, thereby improving the heating efficiency of the liquid. Due to the water level balance principle, the water inside the flow guide 122 will automatically replenish the consumed water on the outer side, thereby realizing the continuous output of ordinary steam, so that there is a continuous supply of ordinary steam in the high-temperature evaporation element 13, thereby improving the efficiency of the induction evaporation device 100 in generating high-temperature steam.

[0059] In some embodiments, the diameter of the steam vent 1221 is 1.9 mm to 2.1 mm.

[0060] Because water has tension, when it flows through the small hole, surface tension resists the water's gravity and other external forces, preventing it from flowing through the hole. By properly setting the diameter of steam vent 1221, it helps ensure that steam vent 1221 has an appropriate diameter, helping to reduce the risk of liquid outside of body guide 122 directly entering liquid chamber 1212 through steam vent 1221, thereby ensuring that liquid entering through liquid inlet 1211 is sufficiently heated to effectively generate steam.

[0061] Among them, the diameter of the steam vent 1221 can be 1.9mm, 1.91mm, 1.92mm, 1.94mm, 1.98mm, 2mm, 2.02mm, 2.05mm, 2.08mm, 2.1mm or other values, which can be set according to actual conditions to ensure that the liquid on the outside of the guide body 122 is not easy to pass through the steam vent 1221.

[0062] In some embodiments, the induction heating assembly 14 includes an induction control member 143, which is electrically connected to the first induction heating member 141 and the second induction heating member 142. The induction control member 143 may be an induction heating driving board.

[0063] In this way, the frequency of the high-frequency alternating current can be adjusted through the induction control component 143 to achieve the adjustment of the heating power and heating speed of the first induction heating component 141 and the second induction heating component 142, so that the first induction heating component 141 and the second induction heating component 142 can achieve heating with different powers, thereby making the outlet temperature of ordinary steam and high-temperature steam controllable, improving the adjustability of the steam output of the induction evaporation device 100, and better adapting to the usage requirements in different scenarios.

[0064] Re-read Figures 1 to 4In some embodiments, the induction evaporation device 100 includes a mounting frame 11, the mounting frame 11 is provided with a fixed space 111 and an accommodating space 112, the mounting frame 11 includes a first frame body 113 and a second frame body 114, the first frame body 113 and the second frame body 114 define the fixed space 111, the first induction heating element 141 and the second induction heating element 142 are located in the fixed space 111, the low-temperature evaporation element 12 and the high-temperature evaporation element 13 are located in the accommodating space 112, and the first frame body 113 separates the fixed space 111 and the accommodating space 112.

[0065] In this way, the first frame 113 can separate the first induction heating element 141 and the low-temperature evaporator 12, which helps to reduce the direct contact between the first induction heating element 141 and the low-temperature evaporator 12, helps to reduce the direct conduction of heat from the low-temperature evaporator 12 to the first induction heating element 141, helps to reduce the loss during the heat energy transfer process, improves the heating efficiency of the first induction heating element 141, and also helps to reduce the direct contact between the first induction heating element 141 and the low-temperature evaporator 12, resulting in damage to the first induction heating element 141 due to excessive temperature, and helps to extend the service life of the first induction heating element 141. The first frame 113 can also separate the second induction heating element 142 and the high-temperature evaporation element 13, which helps to reduce direct contact between the second induction heating element 142 and the high-temperature evaporation element 13, helps to reduce the direct conduction of heat from the high-temperature evaporation element 13 to the second induction heating element 142, helps to reduce the loss during heat energy transfer, improves the heating efficiency of the second induction heating element 142, and thus improves the efficiency of the induction evaporation device 100 in generating high-temperature steam. It also helps to reduce the direct contact between the second induction heating element 142 and the high-temperature evaporation element 13, resulting in damage to the second induction heating element 142 due to excessive temperature, and helps to extend the service life of the second induction heating element 142.

[0066] In addition, the first frame 113 and the second frame 114 can fix the first induction heating element 141 and the second induction heating element 142, which helps to improve the stability of the installation of the first induction heating element 141 and the second induction heating element 142, helps to reduce the situation where the shaking of the first induction heating element 141 and the second induction heating element 142 affects the coupling efficiency of the magnetic field, helps to reduce heat energy loss, improves the heating efficiency of the first induction heating element 141 and the second induction heating element 142, and also helps to improve the efficiency of the induction evaporation device 100 in generating high-temperature steam.

[0067] In some embodiments, the mounting frame 11 is further provided with an avoidance portion 115 . The avoidance portion 115 is connected to the accommodating space 112 . The mounting frame 11 avoids the low-temperature evaporation element 12 and the high-temperature evaporation element 13 through the avoidance portion 115 .

[0068] In this way, the mounting bracket 11 will not hinder the installation of the low-temperature evaporator 12 and the high-temperature evaporator 13, and the mounting bracket 11 will not hinder the electromagnetic induction between the first induction heating element 141 and the low-temperature evaporator 12, and the second induction heating element 142 and the high-temperature evaporator 13, so that the magnetic field generated by the first induction heating element 141 and the second induction heating element 142 is more concentrated, thereby improving the heating efficiency of the first induction heating element 141 and the second induction heating element 142, thereby improving the efficiency of the induction evaporation device 100 in generating high-temperature steam.

[0069] See Figure 5 An embodiment of the present invention provides a heating control method for an induction evaporation device 100 . The heating control method for the induction evaporation device 100 includes step 010 , step 020 , step 030 , and step 040 .

[0070] Step 010: Get steam mode.

[0071] In some embodiments, the steam mode includes a normal steam mode and a high temperature steam mode.

[0072] In some embodiments, the induction evaporation device 100 obtains the steam mode through the induction control component 143 .

[0073] In some embodiments, ordinary steam refers to steam with a temperature of 55°C to 100°C. For example, the temperature of ordinary steam can be 55°C, 65°C, 70°C, 78°C, 88°C, 95°C, 100°C or other temperatures. High-temperature steam refers to steam with a temperature of 380°C. The specific setting can be based on actual conditions.

[0074] Step 020: Determine the corresponding induction heating method according to the steam mode.

[0075] In some embodiments, the induction heating method includes a heating method in which the first induction heating element 141 performs heating work alone and a heating method in which the first induction heating element 141 and the second induction heating element 142 perform heating work in coordination.

[0076] In some embodiments, different steam modes correspond to different induction heating methods. The induction control component 143 selects a suitable induction heating method according to the corresponding steam mode, which helps to more accurately control the heating process, thereby improving thermal energy utilization efficiency, reducing energy waste, and also helping to improve production flexibility and response speed.

[0077] Step 030: When the steam mode is the normal steam mode, the first induction heating element 141 is controlled to perform heating.

[0078] In some embodiments, when the steam mode is the normal steam mode, the induction evaporation device 100 needs to produce normal steam.

[0079] In some embodiments, since ordinary steam has a lower requirement for steam temperature, the heating work of the first induction heating element 141 can achieve the output of ordinary steam. At this time, the induction control element 143 controls the first induction heating element 141 to work alone, and the second induction heating element 142 does not work, so as to reduce the energy waste caused by the operation of the second induction heating element 142.

[0080] In some embodiments, the first induction heating element 141 can heat the liquid in the low-temperature evaporator 12 by induction heating to generate ordinary steam. The first induction heating element 141 can directly generate heat inside the low-temperature evaporator 12, reduce the loss during the heat energy transfer process, and improve the heating efficiency of the first induction heating element 141.

[0081] Step 040: When the steam mode is the high-temperature steam mode, the first induction heating element 141 is controlled to heat, and the second induction heating element 142 is controlled to heat the ordinary steam generated by the first induction heating element 141, wherein the heating power of the second induction heating element 142 is greater than the heating power of the first induction heating element 141.

[0082] In some embodiments, when the steam mode is the high-temperature steam mode, the induction evaporation device 100 needs to produce high-temperature steam.

[0083] In some embodiments, since high-temperature steam has high requirements for steam temperature, the single heating work of the first induction heating element 141 cannot achieve the output of high-temperature steam. At this time, the induction control element 143 controls the first induction heating element 141 and the second induction heating element 142 to work together for heating.

[0084] In some embodiments, the second induction heating element 142 can heat the ordinary steam entering the high-temperature evaporator 13 from the low-temperature evaporator 12 by induction heating to generate high-temperature steam. The second induction heating element 142 can directly generate heat inside the high-temperature evaporator 13, reduce the loss during the heat energy transfer process, and improve the heating efficiency of the second induction heating element 142.

[0085] See Figure 6 In some embodiments, when the steam mode is the high-temperature steam mode, controlling the first induction heating element 141 to heat, and controlling the second induction heating element 142 to heat and heat the ordinary steam generated by the first induction heating element 141 includes steps 041, 042, 043, and 044. That is, step 040 includes steps 041, 042, 043, and 044.

[0086] Step 041 : Obtain a first temperature through the first temperature sensor 15 , and obtain a second temperature through the second temperature sensor 16 .

[0087] In some embodiments, the first temperature sensing element 15 and the second temperature sensing element 16 are installed on the low-temperature evaporator 12, the first temperature sensing element 15 is used to obtain the first temperature in the low-temperature evaporator 12, and the second temperature sensing element 16 is used to obtain the second temperature in the low-temperature evaporator 12, and the sensing control element 143 obtains the first temperature obtained by the first temperature sensing element 15 and the second temperature obtained by the second temperature sensing element 16.

[0088] The detection end of the first temperature sensing element 15 is located on the bottom wall of the low-temperature evaporator 12 , and the detection end of the second temperature sensing element 16 is higher than the detection end of the first temperature sensing element 15 .

[0089] In some embodiments, water is a good heat-conducting medium that can effectively absorb and transfer heat. When there is no water, heat accumulates around the detection end of the temperature sensor, causing the temperature detected by the detection end of the temperature sensor to rise and exceed a preset temperature. When there is water and the detection end of the temperature sensor is submerged in water, the temperature detected by the detection end of the temperature sensor remains at the preset temperature.

[0090] In this way, the first temperature sensor 15 can detect whether there is water in the low-temperature evaporator 12. The first temperature sensor 15 and the second temperature sensor 16 cooperate to determine the liquid level in the low-temperature evaporator 12 based on the detected temperature, thereby timely replenishing water to the low-temperature evaporator 12, ensuring that the low-temperature evaporator 12 has an appropriate liquid level condition and that the low-temperature evaporator 12 has an appropriate amount of water, thereby ensuring the normal operation of the low-temperature evaporator 12. The first temperature sensor 15 and the second temperature sensor 16 can integrate the functions of temperature detection and liquid level detection. The induction evaporation device 100 does not need to include a separate liquid level sensor to detect the liquid level in the low-temperature evaporator 12, which helps to simplify the structure of the induction evaporation device 100 and facilitates manufacturing.

[0091] Step 042: Obtain the difference between the first temperature and the second temperature.

[0092] In some embodiments, the induction evaporation device 100 has a preset difference, which may be 20°C.

[0093] In some embodiments, the sensing control component 143 obtains the first temperature and the second temperature and calculates the difference between the first temperature and the second temperature, and compares the actual difference between the first temperature and the second temperature with a preset difference.

[0094] Step 043: When the difference is greater than or equal to the preset difference, the low-temperature evaporation element 12 is controlled to replenish water.

[0095] In some embodiments, the low-temperature evaporator 12 may have a first liquid level and a second liquid level. When the water in the low-temperature evaporator 12 reaches the first liquid level, it means that there is water in the low-temperature evaporator 12 and the water submerges the detection end of the first temperature sensor 15; when the water in the low-temperature evaporator 12 reaches the second liquid level, it means that there is water in the low-temperature evaporator 12 and the water submerges the detection ends of the first temperature sensor 15 and the second temperature sensor 16.

[0096] In some embodiments, when the difference is greater than or equal to a preset difference, for example, when the difference is greater than or equal to 20°C, it indicates that the water in the low-temperature evaporator 12 submerges the detection end of the first temperature sensor 15 but does not submerge the detection end of the second temperature sensor 16. At this time, the water in the low-temperature evaporator 12 has not reached the second liquid level. The sensing control component 143 controls the low-temperature evaporator 12 to replenish water, for example, controls the low-temperature evaporator 12 to replenish water in a timely manner through the water inlet pipe, thereby reducing the situation where insufficient high-temperature steam output is caused by insufficient liquid level in the low-temperature evaporator 12.

[0097] In some embodiments, the induction control component 143 controls the low-temperature evaporation component 12 to replenish water. When the continuous water replenishment time exceeds 30 seconds and the difference does not decrease, the induction control component 143 controls the first induction heating component 141 to stop working.

[0098] If the difference value does not decrease while the water replenishment time exceeds 30 seconds, it means that the water in the low-temperature evaporator 12 always immerses the detection end of the first temperature sensor 15 but not the detection end of the second temperature sensor 16. The water replenishment rate in the low-temperature evaporator 12 is lower than the evaporation rate of the liquid. Steam is produced in the low-temperature evaporator 12 but there is not enough water to replenish it, resulting in the temperature in the low-temperature evaporator 12 being too high. At this time, the induction control component 143 controls the first induction heating component 141 to stop working, thereby reducing the temperature in the low-temperature evaporator 12 and preventing the low-temperature evaporator 12 from being damaged by dry burning or excessive temperature.

[0099] Step 044: When the difference is less than the preset difference, the low-temperature evaporation element 12 is controlled to stop replenishing water, and the second induction heating element 142 is controlled to heat.

[0100] In some embodiments, when the difference is less than a preset difference, when the difference is less than 20°C, it indicates that the water in the low-temperature evaporator 12 submerges the detection end of the first temperature sensor 15 and the detection end of the second temperature sensor 16. At this time, the water in the low-temperature evaporator 12 reaches the second liquid level, and the sensing control component 143 controls the low-temperature evaporator 12 to stop replenishing water, for example, controls the low-temperature evaporator 12 through the water inlet pipe and stops replenishing water, thereby avoiding unnecessary water inflow and reducing resource waste.

[0101] The induction control component 143 controls the low-temperature evaporation component 12 to stop replenishing water, and controls the second induction heating component 142 to heat, so that the second induction heating component 142 can heat the ordinary steam entering from the low-temperature evaporation component 12 in the high-temperature evaporation component 13 by induction heating to generate high-temperature steam. The second induction heating component 142 can directly generate heat inside the high-temperature evaporation component 13, reduce the loss in the heat energy transfer process, and improve the heating efficiency of the second induction heating component 142.

[0102] See Figure 7 In some embodiments, when the difference is less than a preset difference, the low-temperature evaporator 12 is controlled to stop replenishing water, and the second induction heating element 142 is controlled to heat. Then, when the steam mode is the high-temperature steam mode, the first induction heating element 141 is controlled to heat, and the second induction heating element 142 is controlled to heat and heat the ordinary steam generated by the first induction heating element 141, and also includes steps 045, 046 and 047.

[0103] That is, step 040 includes step 041, step 042, step 043, step 044, step 045, step 046 and step 047, and step 045, step 046 and step 047 are located after step 044. Step 041, step 042, step 043 and step 044 refer to the above embodiment and are not repeated here.

[0104] Step 045: Obtain the third temperature through the third temperature sensor 17.

[0105] In some embodiments, the third temperature sensor 17 is installed on the high-temperature evaporator 13 and is used to obtain the third temperature. The sensing control component 143 obtains the third temperature obtained by the third temperature sensor 17 .

[0106] In some embodiments, the induction evaporation device 100 has a high-temperature steam preset temperature. When the third temperature reaches the high-temperature steam preset temperature, it means that the steam temperature in the high-temperature evaporation element 13 reaches the temperature requirement of the high-temperature steam; when the third temperature is lower than the high-temperature steam preset temperature, it means that the steam temperature in the high-temperature evaporation element 13 has not yet reached the temperature requirement of the high-temperature steam.

[0107] The third temperature sensor 17 can be installed at the steam outlet of the high-temperature evaporator 13 to detect the steam temperature at the outlet in real time to ensure that the high-temperature evaporator 13 produces high-temperature steam that meets the temperature requirements.

[0108] Step 046: When the third temperature is lower than the preset temperature, the second induction heating element 142 is controlled to continue heating.

[0109] In some embodiments, when the third temperature is lower than the preset temperature of the high-temperature steam, it indicates that the steam temperature in the high-temperature evaporator 13 has not yet reached the temperature requirement of the high-temperature steam. At this time, the induction control component 143 controls the second induction heating component 142 to continue heating, so that the steam in the high-temperature evaporator 13 can be in a continuously heated state, so that the steam in the high-temperature evaporator 13 can reach the temperature requirement of the high-temperature steam.

[0110] Step 047: When the third temperature is greater than or equal to the preset temperature, the second induction heating element 142 is controlled to stop working.

[0111] In some embodiments, when the third temperature reaches the preset temperature of high-temperature steam, it indicates that the steam temperature in the high-temperature evaporation element 13 reaches the temperature requirement of high-temperature steam. At this time, the induction control element 143 controls the second induction heating element 142 to stop working, thereby avoiding unnecessary heating work of the second induction heating element 142 and reducing the energy consumption of the induction evaporation device 100.

[0112] In some embodiments, the induction control component 143 controls the low-temperature evaporation component 12 to replenish water. When the continuous replenishment time exceeds 30 seconds and the difference does not decrease, the induction control component 143 controls the first induction heating component 141 and the second induction heating component 142 to stop working.

[0113] If the difference value does not decrease after continuous water replenishment for more than 30 seconds, it indicates that the water in the low-temperature evaporator 12 consistently submerges the sensing end of the first temperature sensor 15 but not the sensing end of the second temperature sensor 16. The water replenishment rate of the low-temperature evaporator 12 is slower than the rate required for liquid evaporation. Steam is being produced in the low-temperature evaporator 12 but insufficient water is available to replenish it. This causes the temperature in the low-temperature evaporator 12 to overheat. Furthermore, the steam produced in the low-temperature evaporator 12 flows to the high-temperature evaporator 13, causing the pressure in the low-temperature evaporator 12 to drop. This indicates that the low-temperature evaporator 12 is overheating and overpressurizing, potentially damaging the low-temperature evaporator 12. At this point, the induction control component 143 controls the first and second induction heating components 141 and 142 to stop operating, thereby reducing the temperature and pressure in the low-temperature evaporator 12 and minimizing the risk of overheating or overpressure damage.

[0114] In summary, in the induction evaporation device 100 and the heating control method for the induction evaporation device 100 provided in the embodiments of the present invention, the high-temperature evaporator 13 is connected to the low-temperature evaporator 12. The induction heating assembly 14 includes a first induction heating element 141 and a second induction heating element 142. The first induction heating element 141 is disposed around the periphery of the low-temperature evaporator 12 and is suitable for heating the liquid in the low-temperature evaporator 12. The second induction heating element 142 is disposed around the periphery of the high-temperature evaporator 13. The heating power of the second induction heating element 142 is greater than that of the first induction heating element 141. The second induction heating element 142 is suitable for heating ordinary steam entering the high-temperature evaporator 13 from the low-temperature evaporator 12. In this way, the first induction heating element 141 can heat the liquid in the low-temperature evaporator 12 through induction heating to generate ordinary steam. The first induction heating element 141 can directly generate heat within the low-temperature evaporator 12, reducing heat loss during heat transfer and improving the heating efficiency of the first induction heating element 141. The second induction heating element 142 can heat the ordinary steam in the high-temperature evaporation element 13 by induction heating to generate high-temperature steam. The second induction heating element 142 can directly generate heat within the high-temperature evaporation element 13, reducing heat loss during heat transfer and improving the heating efficiency of the second induction heating element 142. Furthermore, the induction evaporation device 100 can generate ordinary steam and / or high-temperature steam, thereby enriching the functionality of the induction evaporation device 100 and better adapting to usage requirements in different scenarios. In addition, the first induction heating element 141 is arranged around the periphery of the low-temperature evaporator 12, and the second induction heating element 142 is arranged around the periphery of the high-temperature evaporator 13, which helps to increase the induction area of ​​the first induction heating element 141 and the second induction heating element 142, thereby increasing the heat generation of the first induction heating element 141 and the second induction heating element 142, and also helps to improve the uniformity of heating of the low-temperature evaporator 12 and the high-temperature evaporator 13, avoiding local overheating or insufficient heating, and helping to reduce heat loss caused by heat concentration in a certain area. It also helps to improve the heating efficiency of the first induction heating element 141 and the second induction heating element 142, thereby improving the efficiency of the induction evaporation device 100 in generating high-temperature steam.
