As shown in fig. 1-3, as an embodiment of the present invention, a steam generator is disclosed, which can be used for devices requiring heating and/or steam, such as ironing machines, drying machines, hair beautifiers, etc., and can be heated by the steam generator, or the present invention can be applied to places requiring heating and/or steam, such as sauna rooms, boiler rooms, etc., and also can be used for heating and steam by installing a product body on the steam generator. The utility model discloses a steam generator includes generator housing 3, first heating device 1 and second heating device 2, and generator housing 3 is including the first compartment 31 that is equipped with first heating device 1 and the second compartment 32 that is equipped with second heating device 2.

Compared with some existing steam generators, most of the existing steam generators are only provided with one heating device, cold water directly enters the heating device to be heated, liquefied, steamed and the like, and all the steps are completed by one heating device, so that the waiting time needed by a user in the using process is long, if some users are anxious, the heating device in the steam generator does not sufficiently heat the water, the steam is used when the vaporization is insufficient, and therefore, at the initial starting stage of the ironing machine, the phenomenon that the water is sprayed out in a liquid form after starting is easy to occur, but the use effect of the user is influenced. Furthermore, the utility model discloses a steam generator shell 3 is through the first compartment 31 that is equipped with first heating device 1 and the second compartment 32 that is equipped with second heating device 2, rather than installing first heating device 1 and second heating device 2 in same space, through such two independent heating spaces, not only can carry out heating work simultaneously, reduces heating and steam time, also can avoid two heating devices to the interference of mutual production in during operation water vaporization or heating. In addition, in the present embodiment, the first heat-generating device 1 and the second heat-generating device 2 are both one, and in other embodiments, in order to have better heating and vaporizing effects, a plurality of first heat-generating devices 1 and/or second heat-generating devices 2 may be provided accordingly. In addition, the first compartment 31 and the second compartment 32 in this embodiment are disposed in parallel, which can effectively utilize and save space, and in other embodiments, they can also be disposed in series, or they can be disposed alternately and alternately when there are a plurality of first compartments 31 and second compartments 32.

Further, the first compartment 31 has a plurality of steam chambers 33 arranged from the water inlet to the steam outlet, the plurality of steam chambers 33 being in communication in sequence, the first heat generating means 1 passing through the plurality of steam chambers 33. Therefore, the first compartment 31 mainly heats the heated water again through the first heating device 1 to achieve a vaporization state, and the plurality of sequentially communicated steam chambers 33 of the first compartment 31 sufficiently heat and vaporize the water flow in each chamber, and the vaporized water is led out to the outside, so that the vaporization time is reduced, and if the water flow which is not vaporized in the chambers flows into the next chamber in sequence, the path of the water flow flowing through the first heating device 1 is greatly increased, and the moisture is more fully vaporized. Compared with some existing steam generators, most of the steam generators are only provided with a single chamber, in the process, water flow is fixed at one position and cannot flow in the chamber, so that moisture close to the heating device is heated and vaporized firstly, while moisture far away from the heating device is difficult to heat, so that different areas in the chamber are not uniformly heated and vaporized, and the efficiency is low.

Meanwhile, the second heat generating device 2 comprises a heating tube 21 for temporarily storing the pre-heating water, and a heating body 22 arranged in the tube 21. Therefore, the second heating device 2 mainly preheats the entering cold water through the heating body 22 therein, and effectively controls the water flow, avoids the one end of the heating tube 21 therein being connected with the water inlet port 211 passing through the second compartment 32 and being connected with the external water pipe, and the cold water directly enters the heating tube 21 to be sealed and heated up in a centralized manner, thereby providing a heat basis for heating and liquefying the subsequent steam chamber 33 and improving the heating efficiency. In addition, the other end of the heating pipe body 21 is connected with a water outlet port 212, heated hot water is led out through the water outlet port 212, the water outlet port 212 penetrates through the first compartment 31 to directly enter the steam chamber 33, water flow transmission and circulation between the first compartment 31 and the second compartment 32 are guaranteed, the structure is simple, heat energy loss in a water flow transmission process caused by a complex connecting structure is avoided, and the heating pipe is more timely and effective. The heating tube 21 in this embodiment is longitudinally communicated with the first compartment 31, and the heating body 22 is spirally penetrated through the whole heating tube 21, so as to facilitate sufficient preheating or heating of water flow, and the two ends of the heating tube 21 are respectively provided with the connecting members 214 for conductive heating, thereby making the heating of the whole heating tube 21 more uniform.

In some embodiments, the steam chamber 33 is composed of a plurality of partitions 355 for dividing water flow, and the flowing water flow is blocked or divided by the arrangement and connection of the plurality of partitions 355 to form a certain water flow path, and the water flow is orderly and regularly carried out according to the path, and the water flow does not flow freely in the steam chamber 33. The partition 355 in this embodiment is partially formed by curved plate members having a curvature, and partially formed by straight plate members, so that each steam chamber 33 is formed by connecting a plurality of curved plate members and/or straight plate members, and the cross-sectional shape thereof is also an irregular curved surface, so that the water flow path can be extended, the heating speed can be increased, the water vaporization can be more uniform, the water flow between the adjacent steam chambers 33 can be smoothly transited, and the water flow rate can be increased in the process of flowing through each steam chamber 33. In addition, the partition 355 is partially and/or entirely connected to the end surface of the first heat generating apparatus 1 or the lower end surface of the steam chamber 33, so that part of the water flow path has to pass through part of the end surface of the first heat generating apparatus 1, and the end surface of the first heat generating apparatus 1 is often the region with the highest temperature and the highest heat, so that the water flow can rapidly and sufficiently obtain the heat from the first heat generating apparatus 1 during the water flow passing through the first heat generating apparatus 1, so that the water flow can be heated and vaporized in a short time. In other embodiments, the steam chamber 33 may also be formed by other irregular and curved components with the function of dividing water flow, such as a plurality of arc-shaped chambers formed by curved surfaces surrounding layer by layer; or the partition 355 is not connected with the end face of the first heat generating device 1 and is only connected with the lower end face of the steam chamber, so that the function of dividing the water flow and forming the steam chamber 33 is also realized, but the heating and vaporizing speed is relatively lower, and the main heating and vaporizing functions of the steam chamber 33 are not influenced.

As shown in fig. 4, in other embodiments, the first heat generating device 1 is a heat generating body 11 extending along the arrangement of the plurality of partitions 355, so that the heat generating body 11 is extended according to the arrangement of the plurality of partitions 355, and can be widely and more intensively heated to the plurality of steam chambers 33, thereby improving the heating efficiency, instead of being randomly arranged or installing the heat generating body 11 in each area of the steam chamber 33, which not only has low heating efficiency, but also has a complicated structure and high cost. In this embodiment, the heating element 11 is provided with one heating element and is U-shaped, and this kind of U-shaped structure is equivalent to two parallel heating elements 11, and smooth transition at the junction, has avoided steam chamber 33 dead angle position, effective and maximize utilization space, only through a heating element 11 alright cover most steam chamber 33, simultaneously, has avoided separately setting up a plurality of heating elements 11 and the complicated structure that causes. Compared with some steam generators on the market, a plurality of heating bodies are usually arranged, the heating bodies are distributed in a random extending mode, the heating bodies are directly placed in a single chamber without being designed according to the arrangement of steam chambers or provided with separated chambers, and therefore partial areas in the chamber are completely heated and partial areas are not heated, so that the evaporation is insufficient, and the heating efficiency is low. Furthermore, the utility model discloses a first heating device 1 is equipped with and passes first compartment 31 and external connection's connecing electric port 12, connects electric port 12 in this embodiment to be equipped with two, and connects in the both ends of the U-shaped body, and two of outside accessible connect electric port 12 to act on heating element 11 simultaneously, and the speed of generating heat is very fast. In other embodiments, two or more heating elements 11 in the first compartment 31 may be provided, and may be connected in parallel or in series in the arrangement, or may be provided with an upper layer, a lower layer, and a multi-layer connection structure, although the structure is more complicated, so that the heating efficiency is greatly improved.

In other embodiments, as shown in fig. 5, the first heat generating device 1 may be embedded in the lower end surface of the first compartment 31, i.e. the first heat generating device 1 and the lower end surface of the first compartment 31 are wedged into engagement with each other, rather than being disposed on the end surface of the first compartment 31. In the present embodiment, a portion of the first heat generating device 1 is exposed from the upper end surface of the first compartment 31, and another portion of the first heat generating device 1 is disposed on the lower end surface of the first compartment 31, so that the first heat generating device 1 can form a plurality of concave surfaces 13 and/or convex surfaces 14 on the lower end surfaces of the plurality of steam chambers 33 by the engaging connection between the first heat generating device 1 and the first compartment 31. Specifically, the convex surface 14 protruding from the surface of the steam chamber 33 of the first heating device 1 is the concave surface 13, otherwise, the water flow does not have a smooth surface but needs to flow through the plurality of concave surfaces 13 and/or convex surfaces 14 when flowing through the plurality of steam chambers 33, the contact area between the water flow and the first heating device 1 is increased by the convex surface 14, the heating area is increased, the heat transfer is faster, the concave surface 13 and the convex surface 14 can form a water flow gradient, and the water flow direction is smoother. In addition, the first heat generating device 1 is fitted and connected to the lower end surface of the first compartment 31, and there is a partial overlapping end surface region, so that the first heat generating device 1 can transfer heat energy to the overlapping end surface region by heat transfer, and therefore the lower end surface of the first compartment 31 is also heated, so that the entire first compartment 31 is in a heated state, not only the steam chamber 33 is in a heated/steam region. On the other hand, the first heat generating device 1 is partially exposed from the upper end surface of the first compartment 31, and partially exposed from the lower end surface of the first compartment 31, but not the entire first heat generating device 1 is mounted on the upper end surface or the lower end surface of the first compartment 31, and if the entire first heat generating device 1 is disposed on the upper end surface of the first compartment 31, although the contact area between the water flow and the convex surface 14 is increased, the fall surface between the convex surface 14 and the concave surface 13 is too large, so that the resistance is large, the smooth flow is difficult, and the water flow is slow and easy to block. If the first heat generating device 1 is disposed on the lower end surface of the first compartment 31, the plurality of concave surfaces 13 and/or convex surfaces 14 cannot be formed with the first compartment 31, and the water flow does not contact the first heat generating device 1 and is heated slowly.

In other embodiments, as shown in fig. 6, the first heat-generating device 1 may be disposed in the lower portion of the first compartment 31, separated from the first compartment 31, and provided with a separate third compartment 4. In this embodiment, the lower end surfaces of the first compartment 31 and the second compartment 32 and the lower end surface of the partition 355 of the steam chamber 33 form a partition surface 421, and the partition surface 421 and the peripheral surface of the generator housing 3 together form a chamber 41, so that the chamber 41 is communicated with the lower portion of the entire generator housing 3, and the first heat generating device 1 is disposed in the chamber 41, so that the first heat generating device 1 can radiate and transfer heat to the entire chamber 41 when generating heat, and precisely mainly transfers heat to the partition surface 421. In addition, the partition 355 is formed in a hollow structure to be connected to the end surface of the first compartment 31, so that space is effectively utilized, and heat generated by the first heat generating apparatus 1 can also enter the partition 355, so that the partition 355 also has a heating function, and of course, the second compartment 32 is also heated by the first heat generating apparatus 1, not only by heating the inside of the tube body 21. In addition, in the present embodiment, the first heat generating device 1 in the third compartment 4 is relatively located at the lower part of the steam chamber 33 of the first compartment 31, and a correspondingly shaped curved surface is disposed on the lower end surface of the first compartment 31 according to the shape of the first heat generating device 1, so as to increase the heat receiving area of the end surface, and to make the first heat generating device 1 closer to the first compartment 1, so that the heat is more concentrated, and in addition, the first heat generating device 1 is not in contact with the bottom end surface of the first compartment 31, but has a gap, on one hand, in order to prevent the first heat generating device 1 from being in contact with the end surface for a long time to damage the material or the generator housing 3; on the other hand, if the first heat generating device 1 contacts the first compartment 31, the contact area of the first heat generating device 1 and the first compartment 31 is heated more than the other non-contact areas in a unit time, so the contact area is heated more quickly, and the non-contact area is heated more slowly, which results in uneven vaporization. In other embodiments, the generator housing 3 may also have more chambers than the present embodiment or a plurality of first heat generating devices, for example, a separate chamber is further provided at the lower end of the second compartment 32 for heating the second compartment 32, or a heat generating device is further provided therein, so that the heating or heat preserving performance is better, the vapor is vaporized uniformly and the heating speed is fast.

As shown in fig. 7, in some embodiments, the plurality of steam chambers 33 includes a first chamber 331, a second chamber 332, a third chamber 333, a fourth chamber 334, and a fifth chamber 335 connected in sequence, so that the water flow path is sequentially circulated through the five chambers. Specifically, in this embodiment, the first chamber 331 is the first heating chamber, so the water outlet 212 of the heating tube 21 is partially disposed in the first chamber 331, the water flow of the water outlet 212 can directly reach the steam chamber 33 without passing through other connecting members, the water flow transmission time is reduced, and the heat loss during the water flow transmission process is effectively reduced, in addition, the water flow inlet of the first chamber 331 is disposed at the intersection of the bottoms of the two ends of the U-shaped heating element 11, the contact area of the convex surface 14 of the steam chamber 33 in this area with the water flow is large, and the newly inflowing water can be heated and vaporized quickly. The second chamber 332 is partially connected to the first chamber 331, and further, the second chamber 332 in this embodiment is provided with four partitions 355 which are mutually laterally staggered and parallel and are distributed on the end surface of the left half portion of the first heat generating device 1, so that the partitions 355 laterally staggered in the second chamber 332 are beneficial to guiding the water flow to pass through the end surface of the left half portion of the first heat generating device 1 for multiple times, so as to heat and vaporize the water flow for multiple times. In addition, the water flow paths of the first and

second chambers

331 and 332 pass through half of the end surface of the first heat generating device 1, which is beneficial to rapid heating and vaporization of the water flow in the initial stage. The unvaporized water flow flows to the third chamber 333, the third chamber 333 is mainly formed by separating a part of the partition 355 of the second chamber 332 and the fourth chamber 334, therefore, the third chamber 333 is not arranged at the end face of the first heating device 1, but is connected with the concave surface 13 of the steam chamber, and the third chamber mainly enables the water flow passing through the plurality of concave surfaces 13 and convex surfaces 14 of the first chamber 331 and the second chamber 332 to smoothly transit into the third chamber 333, so that the water flow blockage of the concave surfaces and the convex surfaces in the first two chambers is avoided, the two chambers behind cannot transit, and the functions of connecting and dredging the water flow are achieved. The fourth chamber 334 is longitudinally communicated with the first compartment 31, and the partition plates 355 of the fourth chamber 334 are longitudinally disposed on the convex surface 14 of the steam chamber 33, and precisely, the water flow can flow through the end surface of the right half portion of the first heat generating device 1, so that the fourth chamber 334 is a chamber with the largest contact area between the water flow and the end surface of the first heat generating device 1 in the five chambers, and the water flow flowing through the first three chambers is finally and again heated and vaporized, thereby preventing the water flow from being unvaporized and ensuring that the water vapor to be led out is in a uniform vapor state instead of being combined with the water vapor, which affects the use effect of a user. After the first four chambers are heated and vaporized, the fifth chamber 335 is mainly used for guiding out the vaporized steam, and the fifth chamber 335 is parallel to the fourth chamber 334, so that the steam is guided out sequentially according to a certain direction and rule.
