The utility model provides a steam generator, which comprises a shell, a first heating body and a second heating body. The shell comprises a first cavity and a second cavity which are communicated in sequence. The first chamber is provided with a water filling port communicated with the inner cavity of the first chamber, and the second chamber is provided with an air outlet communicated with the inner cavity of the second chamber. The first heating body is configured to heat the inner cavity of the first chamber, and the second heating body is configured to heat the inner cavity of the second chamber.

When the steam generator is applied to external equipment, the steam generator is horizontally arranged in the external equipment, namely the extending direction or the axial direction of the steam generator or the first heating body and the second heating body is approximately in the horizontal direction or is arranged at a certain angle with the horizontal plane.

When the steam generator is used, the external liquid enters the first chamber from the water injection port, the liquid is heated and atomized under the action of the first heating body to form steam, the formed steam flows into the second chamber along the extending direction of the shell, the second heating body heats the steam for the second time, the temperature of the steam is raised again to form high-temperature steam with higher temperature, and finally the high-temperature steam is discharged from the air outlet. Therefore, the situations that steam loss is large and the steam generator fails due to condensation of water in the flowing process in the pipeline after being discharged from the air outlet can be avoided.

In another embodiment of the present utility model, the steam generator is configured such that external liquid enters the first chamber from the water injection port, the liquid is preheated from normal temperature by the first heating body, and flows into the second chamber along the extending direction of the housing after the temperature is raised, and at this time, the preheated liquid is reheated by the second heating body, so that the preheated liquid can form steam faster after being atomized by heating, and is discharged from the air outlet. The liquid is preheated through the first heating body, so that the time for forming steam by the second heating body can be shortened, the heat in the cavity inside the shell is fully utilized, and the heating efficiency of the steam generator is improved.

According to the steam generator, the two heating bodies are adopted to heat the two inner cavities in the shell respectively, so that the steam generation efficiency can be improved, the steam generation amount can be increased, and the problems of low steam generation efficiency, limited power and the like caused by a single heating body in the prior art are solved. In addition, the steam generator can flexibly regulate and control the working states of the first heating body and the second heating body, so that the steam generator can be applied to more and more complex use environments.

For ease of understanding, the specific structure of the steam generator of the present utility model and its operation principle will be described in detail with reference to fig. 1 to 8 in conjunction with an embodiment.

Referring to fig. 1, the present utility model provides a steam generator which can be used in various intelligent devices requiring steam generation, such as a wireless steam floor washing machine, a wireless steam mop, a wireless eye fumigator, etc. The steam generator is a miniature device, which can be applied to wireless equipment with smaller power and is powered by the battery of the wireless equipment. Of course, the steam generator according to the utility model can also be arranged on a wired installation, which is not described in detail here.

In one embodiment of the utility model, the steam generator is provided on a hand-held cleaning device, such as a hand-held cleaning device known to those skilled in the art as a hand-held cleaner, a hand-held floor cleaner, or the like. The self-moving cleaning device can also be a sweeping robot, a mopping robot, a sweeping and mopping integrated robot and the like. The cleaning apparatus includes a main body 100, a cleaning liquid tank, a sewage tank, a floor brush assembly 101, etc., which are provided on the main body 100. Referring to fig. 8, a floor brush assembly 101 includes a floor brush housing 102, and a floor brush 103 coupled to the floor brush housing, a steam generator disposed in an interior cavity of the floor brush housing 102 and configured to provide steam to a work surface. Specifically, when the cleaning apparatus of the present utility model is a floor scrubber, a user can perform a cleaning operation using the floor scrubber by pushing a hand-held portion of the floor scrubber on the floor and cleaning a work surface with the floor brush in the floor brush assembly 101. In the cleaning process, the cleaning liquid barrel on the floor scrubber can supply water to the floor brush assembly 101 so as to wet the floor brush 103, thereby achieving the cleaning effect of wet mopping the floor. At the same time, the steam generator can generate steam which can act on the working surface to deeply clean dirt on the working surface, so that the cleaning effect of the floor washing machine is improved. The wastewater tank is configured to store wastewater generated during the cleaning process.

As shown in fig. 1 and 2, the steam generator includes a housing 1, a first heating body 5, and a second heating body 6. Wherein the shell 1 is provided with a first chamber 14 and a second chamber 16 which are communicated together in sequence, and further comprises a water injection port 11 communicated with the first chamber 14 and an air outlet 12 communicated with the second chamber 16.

In one embodiment of the utility model, the steam generator has opposite first and second ends in an axial direction of the steam generator, with reference to the orientation of the view of fig. 2. The water filling port 11 is arranged adjacent to a first end of the steam generator and the air outlet port 12 is arranged adjacent to a second end of the steam generator. Referring to fig. 1, in the present embodiment, both the water inlet 11 and the air outlet 12 are protruded outwards from the housing 1, so that the two are conveniently docked with other external devices. For example, the water filling port 11 on the housing 1 may be in communication with a water storage tank and a water pump, which may pump water in the water storage tank into the first chamber 14 through the water filling port 11. The air outlet 12 may be in communication with the jet head so that steam generated by the steam generator may be delivered to the jet head via the air outlet 12 before being applied to the work surface.

Wherein the first heating body 5 is configured to transfer heat into the first chamber 14 to heat the liquid in the first chamber 14 and the second heating body 6 is configured to transfer heat into the second chamber 16 to heat the liquid and/or vapor in the second chamber 16. Therefore, the two inner cavities in the shell are respectively heated by the two heating bodies, so that the steam generation efficiency can be improved, the steam generation amount can be increased, and the problems of low steam generation efficiency, limited power and the like caused by a single heating body in the prior art are solved. In addition, the steam generator can flexibly regulate and control the working states of the first heating body and the second heating body, so that the steam generator can be applied to more and more complex use environments.

In one embodiment of the utility model, the first heating body 5 is configured to preheat the liquid located in the first chamber 14, and the second heating body 6 is configured to heat the preheated liquid and form a vapor. In the use process of the steam generator, external liquid enters the first chamber 14 through the water filling port 11, then is preheated in the first chamber 14 through the first heating body 5, the liquid preheated by the first heating body 5 flows into the second chamber 16 towards the second end along the direction of the shell 1, and the preheated liquid is heated continuously and steam is generated under the action of the second heating body 6. This allows the liquid from the outside to be preheated sufficiently and heated up, and then heated by the second heating body 6 to form steam, which is finally discharged from the air outlet 12 at the second end of the steam generator. The first heating body 5 is used for preheating the external liquid, so that the time for the second heating body 6 to act on the liquid to heat the liquid to form steam is greatly shortened, and the heating efficiency of the steam generator and the heat utilization rate in the steam generator are improved.

In another embodiment of the utility model, referring to fig. 2, the first heating body 5 is configured to heat the liquid located inside the first chamber 14 and form a vapor; the steam is configured to pass through the second chamber 16 and exit the air outlet 12; the second heating body 6 is configured to reheat the steam passing through the second chamber 16 to form high temperature steam.

Specifically, referring to fig. 1 and 2, during use of the steam generator, external liquid enters the first chamber 14 from the water injection port 11 adjacent to the first end of the steam generator, and the liquid entering from the water injection port 11 is heated by the first heating body 5. Specifically, the liquid is atomized by heating to form steam, and along with the continuous generation of steam, the steam moves along the extending direction of the shell 1 towards the second end, during the movement, the steam enters the second chamber 16 and is reheated under the action of the second heating body 6 to form high-temperature steam with higher temperature, and finally the high-temperature steam is discharged from the air outlet 12 adjacent to the second end of the steam generator.

The steam has a higher temperature after being heated again by the second heating body 6 in the second chamber 16, so that the conditions of high steam loss and failure of the steam generator caused by condensation into water and outflow from the pipeline when the steam flows in the pipeline after being discharged from the air outlet 12 can be avoided. Meanwhile, when the steam with higher temperature acts on the working surface, the moisture in the surrounding air is gasified, so that the steam generator can form more aerosol during working, and the use experience of a user is improved.

In one embodiment of the present utility model, referring to fig. 2 and 5, the first heating body 5 includes a heating zone 51 covered with water, and a high temperature zone 52 not covered with water; the water in the heating zone 51 is heated to form steam, which is configured to pass through the high temperature zone 52, the second chamber 16 in this order and to be discharged from the air outlet 12.

Specifically, the first heating body 5 is configured to be disposed gradually upward inclined with respect to the horizontal plane from the first end to the second end, the position adjacent to the first end of the first heating body 5 being the heating zone 51, and the other positions being the high temperature zone 52. In this embodiment, the steam generator is used because the first heating body 5 is gradually inclined upward in the direction from the first end to the second end, i.e., the height of the first heating body 5 adjacent to the first end is lower than the height thereof adjacent to the second end. The location adjacent the first end of the first heating body 5 can be covered by water, so the area covered by water below the water line 53 is denoted as heating area 51. Correspondingly, the position adjacent to the second end of the first heating body 5 is not covered with water, and thus the area not covered with water above the water line 53 is denoted as a high temperature area 52.

In a specific embodiment of the present utility model, taking fig. 1 as an example, the first heating body 5 has a regular rod shape or a cylindrical shape, and the entire circumferential side wall of the first heating body 5 adjacent to the second end portion area is not covered by water, so that the temperature of the high temperature region 52 can be higher, and thus the temperature of the formed steam can also be higher, the high temperature steam is prevented from condensing into water before flowing into the second chamber 16, thereby reducing the loss of the steam generator, reducing the water consumption of the steam generator, and improving the duration of the steam generator.

The steam generator of the present utility model allows water to cover only a portion of the first heating body 5 so that at least a portion of the water entering the steam generator from the water injection port 11 can be atomized by heating to form steam, and moved toward the second chamber 16, and finally discharged from the air outlet 12. The term "covering" according to the present utility model means that the water in the first chamber 14 is in contact with at least the bottom of a certain axial position of the first heating body 5, or extends from the bottom to the side wall position, or covers the entire surface of the first heating body 5 at that axial position. It should be noted here that when the temperature of the first heating body 5 increases, the water covering the position of the first heating body 5 will be brought into a boiling state, and the boiling water will assume a "jumping" state in a partial area of the first heating body 5, which state should also be understood as a water flow covering the first heating body 5. The first heating body 5 may be heated up in its entirety, and when the first heating body 5 is heated up to a predetermined temperature, water is injected into the first chamber 14 through the water injection port 11, and the injected water may take a "jump" state when encountering the first heating body 5 with a higher temperature, which is also understood as a state where the water flow covers the first heating body 5.

In one embodiment of the present utility model, the amount of water entering the first chamber 14 needs to be adjusted, and if too much water is present, the temperature and area of the high temperature zone 52 will be affected, thereby affecting the steam effect.

However, for small-sized devices, the position of the first heating body 5, which is not covered by water, is difficult to maintain at a temperature at which the steam can be reheated due to the power and the volume of the steam generator, so that after the steam is discharged from the air outlet 12 due to the lower temperature, the steam is easily condensed into water in the pipeline due to the lower temperature, so that a large amount of steam is lost, and the condensed water flows out along the pipeline, thereby affecting the normal use of intelligent devices such as wireless eye fumigators.

Based on this, in one embodiment of the present utility model, at least part of the entire circumferential side wall of the first heating body 5 is configured to be uncovered by water, forming the high temperature zone 52. Regardless of whether the first heating body 5 is regular or irregular, it is possible to keep certain positions of the heating body in a "dry-burned" state at all times, as long as the entire circumferential side wall thereof is not covered with water, whereby it is possible to bring the position to a higher temperature, and the steam in the first chamber 14 can maintain the steam state and flow into the second chamber 16.

In one embodiment of the present utility model, referring to fig. 2 and 5, a flange 8 is fixed to the first heating body 5 adjacent to the first end, and the first heating body 5 is connected to the open end of the housing 1 through the flange 8, so that the first heating body 5 may extend in the first chamber 14 and be suspended in the first chamber 14 with a certain interval between the outer surface of the first heating body 5 and the inner wall of the first chamber 14. So that the first heating body 5 can heat the first chamber 14 better.

The flange 8 may be fixed to the surface of the first end of the heating body 2 by welding or in a manner well known to those skilled in the art, the outer surface of the flange 8 may be provided with external threads, and the open end of the housing 1 may be provided with internal threads, whereby the flange 8 and the open end of the housing 1 may be fixed together. In order to ensure the sealing effect between the flange 8 and the housing 1, as shown in fig. 1, a sealing ring can be sleeved on the flange 8, and the sealing ring is used for sealing a gap between the flange 8 and the housing 1 to prevent water from flowing out of the housing 1.

In another embodiment of the present utility model, referring to fig. 6 and 7, the first heating body 5 is configured to be disposed at an outer side surface of the first chamber 14, and heat generated by the first heating body 5 is configured to be transferred into the first chamber 14 through the housing 1. Specifically, the first heating body 5 is configured to be wound on the outer side surface of the first chamber 14 to heat the first chamber 14. In use, the first heating body 5 heats the first chamber 14, so that liquid entering the first chamber 14 from the water filling port 11 can be heated, and as liquid continuously enters the first chamber 14 from the water filling port 11, the liquid in the first chamber 14 moves towards the second end along the direction of the housing 1 and enters the second chamber 16. With continued reference to fig. 6, the second heating body 6 in the second chamber 16 is disposed in the inner cavity of the second chamber 16 and is configured to heat the liquid entering the second chamber 16 to generate steam after heating, and the steam is finally discharged from the air outlet 12.

In another embodiment of the utility model, with continued reference to fig. 6 and 7, the axial side wall of the first chamber 14 is partially covered with water to form a heating zone 51, and a high temperature zone 52 not covered with water. The liquid in the first chamber 14 is heated by the first heating body 5 to generate steam in the heating area 51, the steam flows through the high temperature area 52 along the direction of the shell and is heated, then flows into the second chamber 16, the steam in the second chamber 16 is heated again by the second heating body 6 to form high temperature steam, and finally the high temperature steam is discharged from the air outlet 12. In this embodiment, the circumferential side wall of the first chamber 14 is partially immersed in the liquid, and it is necessary to ensure that the area enclosed by the water-covered side wall of the first chamber 14 is at a temperature required to heat the liquid to form a vapor. So that the first chamber 14 can generate steam by the first heating body 5 and heat the steam.

In one embodiment of the present utility model, referring to fig. 1 and 4, the second heating body 6 is configured to be disposed at an outer side surface of the second chamber 16, and heat generated by the second heating body 6 is configured to be transferred into the second chamber 16 through the housing 1. In another embodiment of the present utility model, referring to fig. 6, the second heating body 6 is located within the second chamber 16 and is configured to heat within the second chamber 16. Specifically, the positional relationship and the action principle between the second heating body 6 and the second chamber 16 are described in detail above, and the disclosure is not repeated here.

In one embodiment of the present utility model, as shown in fig. 2 and 3, the housing 1 includes a first housing 13 enclosing a first chamber 14, and a second housing 15 enclosing a second chamber 16 and interfacing with the first housing 13. The first heating body 5 is configured to extend in the axial direction of the first housing 13, and the second heating body 6 is configured to extend in the axial direction of the second housing 15. The first housing 13 and the second housing 15 may be integrally formed, or may be formed by fastening, and the present utility model is not limited thereto. The extending directions of the first heating body 5 and the second heating body 6 are the same as the setting directions of the first chamber 14 and the second chamber 16 acted by the first heating body 5 and the second heating body 6, so that the inner cavities acted by the first heating body 5 and the second heating body 6 can be heated, the internal space structures of the first chamber 14 and the second chamber 16 can be fully utilized, the corresponding chambers of the first heating body 5 and the second heating body 6 can be quickly heated, and the heating efficiency of the steam generator is improved.

In one embodiment of the utility model, referring to fig. 1 and 3, the first housing 13 and the first heating body 5 constitute a first steam generator; the second housing 15 and the second heating body 6 constitute a second steam generator. In one embodiment of the present utility model, the first heating body 5, the second heating body 6 are configured to be independently controlled. The specific temperatures of the first steam generator and the second steam generator can be controlled respectively, so that the functions of the first steam generator and the second steam generator are regulated, the states of substances generated inside the first steam generator and the second steam generator are controlled through the temperatures, and the flexible regulation of specific work functions based on different application scenes is facilitated.

In a specific embodiment of the present utility model, the first housing 13 and the second housing 15 are hermetically connected by a seal. Thus, after the two are communicated, the condition that the steam generator leaks liquid at the connecting end can be avoided. The seal may be made of a rubber material known to those skilled in the art to maintain the sealing properties of the first and second chambers 14, 16 at the location of their connection ends.

In one embodiment of the present utility model, referring to fig. 2, a filter assembly 3 is disposed between the second housing 15 and the first housing 13. In particular the filter assembly 3 comprises a first sieve 31 covering the junction of the first chamber 14 and the second chamber 16. The liquid entering the first chamber 14 through the water filling port 11 is generally hard water, and after being heated by the first heating body 5, the liquid can generate steam mixed with scale particles, so that in order to prevent the scale particles from flowing to the second chamber 16 along with the steam and being discharged from the air outlet 12, the steam generated in the first chamber 14 can flow through the first filter screen 31, so that the scale particles which cannot be settled and have a particle size larger than the pore diameter of the first filter screen 31 are trapped, the particle size of the scale particles of the steam entering the second chamber 16 is greatly reduced, and the situation that the follow-up air spraying holes, pipelines and other structures are blocked after the steam is discharged from the air outlet 12 can be effectively avoided.

In an embodiment of the utility model, referring to fig. 2 and 5, in order to further reduce the occurrence of clogging of the subsequent structure by scale particles adhering to the steam, a filter assembly 3 is likewise provided in the second chamber 16 adjacent the second end and between the air outlet 12. The filter assembly 3 comprises a second screen 32 covering the air outlet 12. The second filter screen 32 can effectively retain scale particles which cannot be settled in the second chamber 16 and have a particle size larger than the filter screen aperture of the second filter screen 32, and prevent part of the scale particles from being discharged from the air outlet 12 so as to block the subsequent devices. In the present embodiment, the screen pore size of the second screen 32 is configured to be smaller than the screen pore size of the first screen 31, so that the second screen 32 can further intercept scale particles that have not been intercepted by the first screen 31, further reducing the number and size of scale particles in the steam discharged from the air outlet 12. By controlling the screen apertures of the first screen 31 and the second screen 32, the speed of the first screen 31 blocked by scale particles can be slowed down, thereby prolonging the service life of the filter assembly 3.

In another embodiment of the present utility model, referring to fig. 4 and 5, the first chamber 14 and the second chamber 16 are communicated through the communication port 4; the inner diameter of the communication port 4 is smaller than the inner cavities of the first chamber 14 and the second chamber 16. In the present embodiment, the generated steam in the first chamber 14 passes through the first filter screen 31 and then enters the second chamber 16 from the communication port 4, so that the flow path of the steam can be restricted. As shown in fig. 5, the second end of the first chamber 14 and the first end of the second chamber 15 are closed, and a communication port 4 is formed at each end, the communication port 4 is located at the center of each end, and the inner diameter is smaller than the inner diameter of the first chamber 14 and the second chamber 15. This allows the steam formed in the first chamber 14 to flow from the communication port 4 to the second chamber 16, and then to be heated uniformly by the second heating body 6, so as to achieve rapid temperature rise. In addition, liquid or scale particles in the second chamber 14 are prevented from reversing over the communication port 4.

In one embodiment of the present utility model, as shown in fig. 2 and 5, a scale storage chamber 9 communicating with the first chamber 14 is provided in the first chamber 14, and the scale storage chamber 9 is provided at a side adjacent to the high temperature region 52 and configured to contain scale.

Since the first heating body 5 continuously heats the water in the first chamber 14 during the use of the steam generator, the water containing the soluble calcium and magnesium compounds has insoluble calcium or magnesium salts separated out after boiling, namely scale particles; and scale particles in the steam may adhere to the walls of the first chamber 14 after contacting the walls of the first chamber 14. Thus, as the steam generator is used, scale on the walls of the first chamber 14 builds up more and more. After setting up and depositing the dirty chamber 9 for the in-process that the high temperature steam of mixed scale granule flows to second cavity 16, the incrustation scale granule can deposit in depositing dirty chamber 9 under the effect of gravity to slow down the deposit speed of incrustation scale, and then extension steam generator's life.

In one embodiment of the present utility model, as shown in fig. 2 to 5, the steam generator of the present utility model is provided with a temperature measuring assembly, and a detecting point of the temperature measuring assembly is disposed at a position corresponding to the high temperature region 52 inside the first heating body 5 and is used for measuring the temperature of the high temperature region 52. Specifically, the temperature measuring component may be a thermocouple detecting element or a thermistor detecting element, etc. When the temperature measuring component is a thermocouple detecting element, the connection point of the two hot electrodes is the detection point of the thermocouple detecting element; when the temperature measuring component is a thermistor detecting element, the position of the thermistor is the detecting point of the thermistor detecting element. After the temperature of the high temperature region 52 is obtained, the steam generator of the present utility model can adjust the heating power of the first heating body 5, thereby ensuring that the first heating body 5 can normally heat water into steam. Of course, the temperature measuring assembly may also be disposed at a position corresponding to the high temperature region 52 inside the second heating body 6, and the specific principle thereof is the same as that of the first heating body 5, and the present utility model will not be described herein in detail.

In one embodiment of the present utility model, a control unit (not shown) is further included, and the control unit is configured to control the heating power of the heating zone 51 and the flow rate of water entering the first chamber 14 from the water injection port 11 based on the temperature collected by the temperature measuring assembly. Specifically, when the highest surface temperature of the high temperature region 52 is lower than a preset value, the control unit may control the water pump to reduce the water flow rate entering the first chamber 14 or increase the heating power of the heating region 51; when the highest surface temperature of the high temperature zone 52 is higher than the preset value, the control unit may control the water pump to increase the water flow rate into the first chamber 14 or decrease the heating power of the heating zone 51, or directly close the first heating body 5 and/or the second heating body 6.

In order to avoid explosion accidents after faults such as unsmooth water intake, dry heating, overhigh heating power and the like generated by the steam generator, as shown in fig. 2 and 5, the outer side of the shell 1 is also provided with a temperature control component 7 and a temperature fuse, wherein the temperature control component 7 can turn off a power supply when the temperature of the shell 1 exceeds a set temperature and turn on the power supply when the temperature is lower than the set temperature; the temperature fuse can be automatically fused to cut off the power supply of the first heating body 5 and the second heating body 6 after the temperature is higher than the fusing temperature. By providing the temperature control assembly 7 and the temperature fuse, the steam generator can be prevented from being excessively high in temperature, thereby causing accidents.

The utility model also provides intelligent equipment which can be equipment needing to spray steam, such as a wireless steam floor washing machine, a wireless steam mop or a wireless fumigation instrument, and the like, wherein the intelligent equipment is provided with the steam generator. The function of the individual structures of the steam generator is referred to above and is not illustrated here.

Application scenario one

The user turns on the switch of the intelligent device provided by the utility model, and after the intelligent device is turned on, the steam generator and the water pump are controlled to be started. Water in the reservoir is continuously pumped by the water pump from the water filling port 11 into the first chamber 14.

Referring specifically to fig. 5, water pumped by the water pump is introduced into the first chamber 14, and then preheated in the first chamber 14 by the first heating body 5, and introduced into the second chamber 16 through the communication port 4 after the preheating is completed. The water entering the second chamber 16 will be heated by the second heating body 6 and form steam, which will eventually be discharged from the air outlet 12 adjacent the second end of the steam generator. The liquid entering the first chamber 14 from the water injection port 11 is preheated through the first heating body 5 in advance, so that the time for the preheated liquid to be heated and form steam by the second heating body 6 is reduced, and the steam generating efficiency of the steam generator is improved.

Application scene two

The user turns on the switch of the intelligent device provided by the utility model, and after the intelligent device is turned on, the steam generator and the water pump are controlled to be started. Water in the reservoir is continuously pumped by the water pump from the water filling port 11 into the first chamber 14.

Referring to fig. 2 and 5, during the use of the steam generator, water pumped by the water pump enters the first chamber 14 from the water injection port 11, the liquid entering the first chamber 14 is boiled at the heating area 22 in the first heating body 5 under the action of the first heating body 5, and part of high-temperature liquid water is splashed by boiled water vapor, so that a mixture of gaseous water and high-temperature liquid water is formed. The mixture of gaseous water and high temperature liquid water will continue to move along the housing in the direction of the second end and be sufficiently heated by the high temperature zone 52 during the movement. Referring to fig. 4, when the steam flows into the second chamber 16, it is heated again by the second heating body 6 to form high temperature steam having a relatively high temperature, and finally the high temperature steam is sprayed from the air outlet 12.

After the steam is heated again under the action of the second heating body 6, the condition that the steam is condensed into water and flows out of the pipeline when flowing in the pipeline, so that the steam loss is large or the steam generator fails can be avoided. In addition, after the high-temperature steam is discharged from the air outlet 12 of the steam generator, the temperature difference between the high-temperature steam and the outside air is larger, and the moisture in the air can be gasified by the high-temperature steam, so that more steam is formed, and the steam generation amount of the steam generator is increased.
