A steam generator 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 5.

The steam generator 100 according to an embodiment of the present invention may include: a steam generating part 1.

As shown in fig. 1 and 2, the steam generating part 1 can generate steam and can discharge the generated steam out of the steam generator 100 for cleaning the ground by the steam mop, wherein the steam generating part 1 is provided with a liquid inlet 11 and an air outlet 12, the liquid inlet 11 is suitable for being communicated with an external water source, and when in use, liquid water in the external water source is suitable for entering the steam generating part 1 from the liquid inlet 11, is converted into steam through the heating evaporation effect of the steam generating part 1, and is finally discharged out of the steam generating part 1 from the air outlet 12.

Further, the steam generating section 1 includes: a housing 13 and a heat generating core 14, the heat generating core 14 being at least partially disposed within the housing 13. That is, the casing 13 is sleeved outside the heat generating core 14, so as to protect the heat generating core 14 and provide an evaporation space for the heat generating core 14. Wherein, a first parallel channel 2 and a second parallel channel 3 which are arranged in parallel are formed between the heating core 14 and the shell 13, and each parallel channel is communicated with the liquid inlet 11 and the air outlet 12.

That is, the liquid water flowing in from the liquid inlet 11 is converted into vapor by the heating evaporation of the heating core 14, and is finally discharged from the air outlet 12 through the first parallel passage 2 and the second parallel passage 3 at the same time. Because the parallel channels are adopted for simultaneously discharging air, the air discharging speed can be effectively improved, and the air outlet 12 can be prevented from being blocked by scale, so that the anti-blocking effect is realized, and the service life of the steam generator 100 is prolonged.

Still further, as shown in fig. 4, the heat generating core 14 includes a core print 141 and a heating portion 142 at least partially disposed within the core print 141. That is, the heating part 142 is disposed inside the cartridge 141, and the housing 13 is disposed outside the cartridge 141, and the first parallel passage 2 and the second parallel passage 3 are further provided between the housing 13 and the cartridge 141, so that the heating part 142 is isolated from the housing 13, thereby preventing the heating part 142 from directly heating the housing 13, and reducing the outer surface temperature of the housing 13 and the steam generator 100.

According to the steam generator 100 of the embodiment of the invention, the steam generator 100 can effectively increase the air outlet speed to realize quick air outlet, can effectively reduce the temperature of the outer surface of the steam generator, and can also avoid the occurrence of scale blockage phenomenon to prolong the service life of the steam generator.

According to some embodiments of the invention, the extension lengths of the first parallel channel 2 and the second parallel channel 3 are different. For example, the length of the first parallel passage 2 is longer than the length of the second parallel passage 3 (see fig. 2). Therefore, the parallel arrangement of the long and short channels can be realized, and the air outlet speed is further improved.

Referring to the embodiment shown in fig. 2-4, the cartridge 141 has a first surface 143 and a second surface 144 opposite each other. For example, the first surface 143 is the front face of the core print 141 and the second surface 144 is the back face of the core print 141. The first surface 143 of the core seat 141 is provided with a first heating rib assembly 4 corresponding to the liquid inlet 11, the first heating rib assembly 4 can heat the liquid water flowing in from the liquid inlet 11 to evaporate the liquid water, and the contact area between the first heating rib assembly 4 and the liquid water can be increased by setting the first heating rib assembly 4, so that the liquid water contacts with the first heating rib assembly 4 more fully, the heating efficiency is higher, and more steam is generated in unit time, thereby improving the air outlet speed and the air outlet efficiency.

Moreover, the first heating rib assembly 4 can fully heat the liquid water so as to ensure that the air outlet temperature is higher, and can fully convert the liquid water into steam so as to realize superheated steam, thereby avoiding the water spraying phenomenon of the air outlet 12.

Wherein the first parallel passage 2 and the second parallel passage 3 are located on one side of the first surface 143 of the cartridge 141. That is, the first parallel passage 2 and the second parallel passage 3 are located on the same side as the heating passage where the first heating rib assembly 4 is located and are communicated to realize a parallel arrangement.

As shown in fig. 2, the first parallel channels 2 and the second parallel channels 3 are two groups, wherein the first group of first parallel channels 2 and the second parallel channels 3 and the second group of first parallel channels 2 and the second parallel channels 3 are symmetrically arranged about the first heating rib assembly 4, and the first heating rib assembly 4 is arranged in a central area of the first surface 143 of the mandrel holder 141. Thereby, the parallel arrangement of the two groups of parallel channels is realized, so that the steam generated at the first heating rib assembly 4 can reach the air outlet 12 through the two groups of parallel channels at the same time, thereby further improving the air outlet speed.

The first heating rib assembly 4 is arranged in the central area of the first surface 143 of the core holder 141, so that the air outlet speeds of the two groups of parallel channels are the same, and the phenomenon of turbulence is avoided to influence the air outlet speed.

Wherein, first heating muscle subassembly 4 includes: the upper heating ribs and the lower heating ribs are staggered up and down, so that the dropped liquid water can be fully contacted and evaporated with the first heating rib component 4, and the air outlet speed is further improved.

Referring to fig. 2, the first parallel passage 2 has a first inlet 21, the second parallel passage 3 has a second inlet 31, and the vapor generated at the first heater rib assembly 4 is adapted to enter the first parallel passage 2 from the first inlet 21 and simultaneously enter the second parallel passage 3 from the second inlet 31.

Wherein, the distance between the first inlet 21 and the liquid inlet 11 is smaller than the distance between the second inlet 31 and the liquid inlet 11. That is, the first inlet 21 is disposed above the second inlet 31, and the proximal end of the first heater bar assembly 4 is close to the liquid inlet 11 and the distal end is away from the liquid inlet 11, and the distal end of the first heater bar assembly 4 protrudes from the second inlet 31 in a direction away from the liquid inlet 11. Thereby, the liquid water dropped to the bottom of the heating channel can not directly flow into the first parallel channel 2 and the second parallel channel 3 from the second inlet 31 and the first inlet 21, and the water spraying phenomenon of the air outlet 12 is avoided.

As shown in fig. 2, the first parallel passage 2 is formed by a plurality of first folding plates 22 arranged at intervals, and the second parallel passage 3 is formed by a plurality of second folding plates 32 arranged at intervals, and by arranging the first folding plates 22 and the second folding plates 32, the phenomenon of baffling occurs when vapor passes through the first parallel passage 2 and the second parallel passage 3, so that the liquid water which is not evaporated in the vapor can be filtered, and only the vapor sprayed out from the air outlet 12 can be effectively prevented from spraying water at the air outlet 12.

Wherein the first and second return plates 22 and 32 are integrally formed on the first surface 143 of the core print 141 and are configured as thermally conductive return plates. That is, the first and second return plates 22 and 32 can further heat the vapor and liquid water flowing therethrough, thereby further increasing the gas outlet speed and the gas outlet temperature and further effectively preventing the water spray phenomenon from occurring.

Referring to the embodiment shown in fig. 2-4, the cartridge 141 has a side 145 connecting the first surface 143 and the second surface 144, and the outlets of the first parallel passage 2 and the second parallel passage 3 converge to form a common outlet 5, with the common outlet 5 converging at the side 145 of the cartridge 141. Therefore, a further water blocking effect can be realized, so that the water spraying phenomenon is avoided.

Further, as shown in fig. 3 to 5, the second surface 144 of the core print 141 is formed with a third parallel channel 6 and a fourth parallel channel 7 arranged in parallel, the third parallel channel 6 communicates with the common outlet 5 on one side of the core print 141 to further communicate with one group of parallel channels, and the fourth parallel channel 7 communicates with the common outlet 5 on the other side of the core print 141 to further communicate with the other group of parallel channels, wherein both the third parallel channel 6 and the fourth parallel channel 7 communicate with the air outlet 12, thereby realizing two vapor channels on both sides of the core print 141, which can simultaneously perform air outlet to enhance the air outlet speed.

Referring to fig. 2, the first outlet 23 of the first parallel passage 2 is located at the upper end of the common outlet 5, and the second outlet 33 of the second parallel passage 3 is located at the lower end of the common outlet 5. I.e. the first outlet 23 is arranged above the second outlet 33. That is, the first parallel passage 2 is an upper passage and the second parallel passage 3 is a lower passage, thereby realizing a parallel arrangement of the upper and lower passages to further avoid the occurrence of the clogging phenomenon of scale, thereby further improving the service life of the steam generator 100.

As shown in fig. 5, the third parallel passage 6 and the fourth parallel passage 7 are separated from each other by a partition 8 to achieve parallel connection of the third parallel passage 6 and the fourth parallel passage 7.

Further, the partition 8 is provided on the second surface 144, and the partition 8 has a partition passage 82 (overheat passage) therein, wherein one end of the partition passage 82 communicates with the outlets of the third parallel passage 6 and the fourth parallel passage 7 and the other end communicates with the air outlet 12, thereby achieving communication of the third parallel passage 6 and the fourth parallel passage 7 with the air outlet 12.

Specifically, after vapor enters the third parallel passage 6 and the fourth parallel passage 7 from the two sets of parallel passages, respectively, the vapor may enter the separator passage 82 from the separator passage inlet 81 and eventually exit from the air outlet 12.

Wherein the divider channel inlets 81 are located at the upper ends of the third parallel channel 6 and the fourth parallel channel 7. Thus, vapor can be easily introduced from the partition passage inlet 81, and liquid water is not easily introduced from the partition passage inlet 81, thereby realizing water spray prevention.

Still further, each of the third parallel passage 6 and the fourth parallel passage 7 is concavely formed with respect to the second surface 144 of the core print 141, and third turn-back plates 9 are further provided at intervals in the third parallel passage 6, and fourth turn-back plates 10 are further provided at intervals in the fourth parallel passage 7. The third parallel channel 6 and the fourth parallel channel 7 are respectively configured as auxiliary overheating channels, and the water spraying and the air outlet temperature raising can be further reduced through the design of the auxiliary overheating channels matched with the turning plate.

The following describes the gas outlet process of the steam generator 100 with reference to fig. 1 to 5:

firstly, external liquid water enters the liquid inlet channel through the liquid inlet 11 and drops onto the first heating rib component 4 to be heated and evaporated into vapor initially, then the mixture of the vapor and the liquid water is continuously heated through the two groups of parallel channels and further converted into more vapor, meanwhile, scale is separated out, then the vapor reaches the third parallel channel 6 and the fourth parallel channel 7 through the two common outlets 5 respectively and is further removed from the scale and heated and evaporated, finally the vapor enters the separator channel 82 from the separator channel inlet 81 to be heated, so that the temperature of the vapor is higher, and finally the high-temperature vapor is discharged out of the steam generator 100 from the air outlet 12.
