Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of steam household appliances, and in particular relates to a steam generator. Background Art
[0002] As steam generators are increasingly used in household appliances, there are more and more steam generators with various functions and structures. Due to the functional characteristics of steam generators, when the vaporized water vapor is discharged, most of the minerals in the water will remain inside the steam generator, and only a small part will be carried out of the steam generator cavity with the high-speed discharge of steam. Minerals remain in the water, and scale is produced. In some household appliances, since the steam function is an auxiliary function, there is no separate citric acid cleaning program or ion exchange resin module to solve the scale problem, so the ability of the steam generator to retain scale determines the service life of the steam generator. At present, the traditional solution is mainly to block scale by setting interception devices such as screens and baffles to prevent scale from blocking the air outlet and causing the steam generator to fail. However, under the traditional solution, scale will be excessively concentrated at the interception device to form a blockage, which will eventually make the interception device fail, resulting in a short service life of the steam generator. Summary of the invention
[0003] In view of the deficiencies existing in the related art, the purpose of the present invention is to provide a steam generator to solve the problems raised in the above background technology.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0035] See attached Figures 1 to 6 , a schematic embodiment of the steam generator proposed by the utility model is given, the steam generator includes a main body 1 with a heating chamber 11 and an upper opening, an upper cover 2 arranged at the upper opening and a heating pipe 12 arranged in the heating chamber 11, the main body 1 is provided with a water inlet 101 and a steam outlet 102, and also includes a first baffle 3, a second baffle 4, a third baffle 5 and a fourth baffle 6.
[0036] The water inlet 101 and the steam outlet 102 can be set at the set position of the body 1 according to actual needs. At the same time, the water inlet 101 and the steam outlet 102 can be set in multiple positions according to actual needs. In this embodiment, the water inlet 101 and the steam outlet 102 are each provided with one, respectively, and are provided at both ends of the body 1.
[0037] The first baffle plate 3 is disposed in the heating chamber 11, and the first baffle plate 3 is close to the water inlet 101. The second baffle plate 4 is disposed on the side wall in the heating chamber 11, and the second baffle plate 4 is located in the middle of the heating chamber 11. The third baffle plate 5 is disposed in the heating chamber 11, and the third baffle plate 5 is located in the middle of the heating chamber 11, and the third baffle plate 5 and the second baffle plate 4 are arranged alternately. The fourth baffle plate 6 is disposed in the heating chamber 11, and the fourth baffle plate 6 is close to the steam outlet 102. In this embodiment, the third baffle plate 5 and the second baffle plate 4 are arranged alternately along the line connecting the water inlet 101 and the steam outlet 102.
[0038] In this embodiment, two first baffles 3 are provided, and the two first baffles 3 are arranged in an eight-shaped shape, and the gap between the two first baffles 3 is aligned with the water inlet 101. Two flow paths are formed near the water inlet 101 in the heating chamber 11. Figure 6 , the arrow in the figure indicates the direction of water flow. When the temperature of the steam generator is too high, the main engine will increase the water supply to reduce the temperature and avoid abnormal operation. At this time, the water flows faster and the water will rush out of the water inlet 101 farther, fall into the gap between the two first baffles 3, and pass through the gap to directly enter the middle of the heating chamber 11. When the temperature of the steam generator is normal, the water flow is small and the flow rate is slow. The water flows along the position of the water inlet 101, and flows naturally to both sides after entering the heating chamber 11, and flows to the middle of the heating chamber 11 through the main channel. The length of the water channel is extended, which increases the heat exchange area.
[0039] A plurality of second baffles 4 are provided, and the plurality of second baffles 4 are arranged at a set distance on the side wall of the heating chamber 11. The second baffle 4 is an L-shaped plate composed of a long plate 41 and a short plate 42, one end of the long plate 41 is connected to the side wall of the heating chamber 11, and the long plate 41 and the side wall of the heating chamber 11 are at a set angle to form the first storage area 7, and the short plate 42 is oriented away from the side wall of the heating chamber 11.
[0040] The third baffle 5 includes a V-shaped plate 51 to form a second storage area 8, and the opening of the third baffle 5 faces the water inlet 101. The third baffle 5 also includes an extension plate 52, which is connected to the V-shaped plate 51 at a set angle and is parallel to the short plate 42.
[0041] In this embodiment, a plurality of third baffles 5 are provided, and the plurality of third baffles 5 are arranged at a set distance in the middle of the heating chamber 11. The plurality of third baffles 5 are arranged alternately with the plurality of second baffles 4, so that the water flow path is two sets of symmetrical, centrally merged serpentine flow paths, which extend the overall flow path length and improve the heat exchange effect. The dual-channel design can ensure that when one of the channels is blocked, the steam generator can continue to work, reducing the impact of the blockage on the whole machine. In addition, if the space width is limited, a single-channel design can be used instead of the dual-channel design of this embodiment.
[0042] The fourth baffle 6 is a rectangular plate. Two fourth baffles 6 are provided. The two fourth baffles 6 are respectively arranged on both sides of the steam outlet 102 . The two fourth baffles 6 are perpendicularly arranged to the side wall where the steam outlet 102 is located to form a third storage area 9 .
[0043] In some embodiments, the first baffle 3, the second baffle 4, the third baffle 5 and the fourth baffle 6 are integrally die-cast with the body 1, and the overall structure has strong stability and is not prone to loosening during use.
[0044] In some embodiments, the first baffle 3, the second baffle 4, the third baffle 5 and the fourth baffle 6 are separately installed on the main body 1, with a modular structure, which improves adaptability. When damaged and repaired, only part of the baffles can be replaced, which is low-cost.
[0045] In order to automatically sample and monitor the temperature in real time and realize over-temperature protection, in this embodiment, the steam generator also includes a temperature control protection device 10, which is arranged at the bottom of the main body 1. The temperature control protection device 10 is electrically connected to the heating tube 12, thereby improving the safety of the steam generator.
[0046] To facilitate wiring, in this embodiment, the wiring end of the heating tube 12 passes through the side wall of the body 1 and extends to the outside of the body 1 .
[0047] In the above exemplary embodiment, the steam generator forms multiple storage areas by arranging the second baffle, the third baffle and the fourth baffle, so that scale can be evenly distributed in the heating chamber, improving space utilization and avoiding excessive concentration of scale in the same place to form blockage.
[0048] The following is combined with Figures 1 to 6 The working process of an embodiment of the steam generator of the utility model is described as follows:
[0049] See attached Figure 6 , water enters the heating chamber 11 from the water inlet 101, and flows in a serpentine manner on both sides in the direction of the arrow shown in the figure. The first storage area 7, the second storage area 8 and the third storage area 9 are all located at the water flow corners. When the steam generator generates scale, part of the scale flows along the direction of the water flow. Due to the movement characteristics of the water flow and air flow itself, the large-mass scale particles will be thrown into the storage area by centrifugal force at the water flow corner for retention, and then the steam-water mixture continues to flow. Since multiple storage areas are set, the scale generated by the steam generator will be dispersed and stored inside the heating chamber 11.
[0050] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0051] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
