[0049] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0050] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0051] In the description of the present utility model, it should be noted that the terms "upper", "lower", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.

[0052] like Figure 1-2 As shown, this embodiment provides a garment steamer, which includes a water tank 100 and a steam generator 200. The steam generator 200 is located above the ironing panel 1, and the water tank 100 is arranged above the steam generator 200. The upper wall of the steam generator 200 is provided with a water inlet hole k, and the water in the water tank 100 is transported from the water inlet hole k to the steam generator 200 through a water pump. The steam generator 200 heats the water to generate steam, and the steam is ejected from the steam outlet hole y of the ironing panel 1 to iron the clothes.

[0053] like Figure 2-5As shown, in this embodiment, a dual-flow channel steam generator 200 is provided, comprising a shell 21 and a heating element 22; the shell 21 comprises a steam cavity C and a heating element channel S, and the heating element channel S is located below the steam cavity C. The ironing panel 1 may be an independent component close to the lower surface of the steam generator 200, or may be a part of the shell 21 of the steam generator 200, that is, in the latter case, the lower surface of the shell 21 is the ironing panel 1.

[0054] The ironing panel 1 and the shell 21 of the steam generator 200 are an integral structure, which is not only more compact and beneficial to the steam output efficiency of the steam generator 200, but also the temperature of the heating element 22 and the steam cavity C can be quickly transmitted to the ironing panel 1, thereby effectively utilizing heat energy to achieve the ironing function.

[0055] like Figure 6 As shown, there are multiple isolation walls q in the steam cavity C, and the isolation walls q separate the steam cavity C into a first flow channel L1 and a second flow channel L2; the first flow channel L1 and the second flow channel L2 are symmetrically arranged on both sides of the central axis of the shell 21, and each flow channel is a circuitous spiral flow channel. The arrangement of the circuitous spiral flow channel can increase the length of the flow channel as much as possible. Moreover, the local isolation wall of the circuitous spiral flow channel has a corner v, forming a barrier in the direction of water flow, which can intercept scale deposition in various areas of the flow channel to reduce the amount of scale accumulation at the end of the flow channel.

[0056] like Figure 4-6 As shown, the heating element 22 is located in the heating element channel S and is close to the lower wall of the steam cavity C. The heating element 22 passes through the space vertically projected downward by the first flow channel L1 and the second flow channel L2. This arrangement makes the distance between the heating element 22 and the flow channel closer, the heating efficiency is higher and faster, and the heat loss is smaller.

[0057] The upper wall of the shell 21 is provided with a water inlet interface 2 and at least one water inlet hole k located in the water inlet interface 2, and the water inlet hole k is connected to the steam cavity C. The starting ends of the first flow channel L1 and the second flow channel L2 are located on the same side of the shell 21 and are adjacent to or butted against each other, and the water inlet hole k is connected to the first flow channel L1 and the second flow channel L2. The lower wall of the shell 21 is provided with a plurality of steam outlet holes y corresponding to the first flow channel L1 and the second flow channel L2, respectively, and the steam outlet holes y are connected to the steam cavity C; the steam outlet holes y are located at the end of the first flow channel L1 or the second flow channel L2.

[0058] By setting a flow channel structure that allows water to flow in from a water inlet interface 2 and then branch on both sides, the water flow can be quickly and evenly distributed to the entire steam cavity C, thereby improving the steam generation efficiency and making the temperature of the ironing panel 1 more uniform.

[0059] In this embodiment, if Figure 3-9As shown, the starting ends of the first flow channel L1 and the second flow channel L2 are separated from each other by the starting end isolation wall, and the starting end isolation wall is separated from the upper inner wall of the steam chamber C by a certain distance to form a gap 3 connecting the first flow channel L1 and the second flow channel L2. Two water inlet holes k spaced from each other are provided in the water inlet interface 2, and the water inlet holes k extend inward to form a water inlet column g, each water inlet column g extends to the bottom of the gap and corresponds to the starting end of the first flow channel L1 or the second flow channel L2 respectively. Therefore, no matter how the steam generator 200 is tilted, the water in the water guide pipe can be distributed to the first flow channel L1 and the second flow channel L2 respectively through the water inlet holes k in the water inlet interface 2, eliminating the possibility of water flowing into only one flow channel. The setting of the gap ensures the mutual circulation of water in the two flow channels, which is more conducive to the uniformization of water, thereby ensuring the consistency of temperature on both sides. Preferably, in this embodiment, the first flow channel L1 and the second flow channel L2 are also partially connected on the side away from the starting end.

[0060] Of course, the setting of the starting end of the first flow channel L1 and the second flow channel L2 and the water inlet k is not limited to the scheme provided in this embodiment. It can also present other different structures. For example, the starting ends of the first flow channel L1 and the second flow channel L2 are isolated from each other by the starting end isolation wall, and two water inlet holes k spaced apart from each other are provided in the water inlet interface 2, and each water inlet hole k corresponds to the starting end of the first flow channel L1 or the second flow channel L2 respectively. In this way, no matter how the steam generator 200 is tilted, the water in the water guide pipe can be distributed to the first flow channel L1 and the second flow channel L2 respectively through the water inlet hole k in the water inlet interface 2. The mutual communication between the two flow channels can be achieved by the connection of other areas of the flow channels. For example, as in the present embodiment, the first flow channel L1 and the second flow channel L2 are partially connected on the side away from the starting end.

[0061] For another example, the starting ends of the first flow channel L1 and the second flow channel L2 are separated from each other by a starting end isolation wall, and the starting end isolation wall is separated from the upper inner wall of the steam chamber C by a certain distance to form a gap connecting the first flow channel L1 and the second flow channel L2; a water inlet hole k is provided in the middle of the water inlet interface 2, and the water inlet hole k corresponds to the gap. In this way, the water in the water guide pipe can also be distributed to the first flow channel L1 and the second flow channel L2 through the water inlet hole k in the water inlet interface 2. Similarly, under such an embodiment, the first flow channel L1 and the second flow channel L2 can also be partially connected on the side away from the starting end.

[0062] like Figure 4 As shown, the housing 21 includes a lower housing 21b made of aluminum die-casting and an upper housing 21a made of aluminum sheet. Aluminum has good thermal conductivity. The lower housing 21b and the heating element 22 are formed by insert die-casting, so that the connection between the steam cavity C and the heating element 22 is relatively firm, thereby improving the sealing of the steam generator 200. The lower housing 21b and the upper housing 21a are connected together by liquid heat-resistant silicone.

[0063] like Figure 4-6 As shown, the lower shell 21b includes an upwardly open groove and a heating element channel S leading to the bottom of the groove. The heating element channel S is a transverse channel structure in the entity below the groove. The heating element is a heating pipe, and the heating pipe leads to the heating element channel S from the side. Multiple vertical isolation walls q are located in the groove of the lower shell 21b, and the upper shell 21a closes the groove to form a steam cavity C; the isolation wall q divides the steam cavity C into a first flow channel L1 and a second flow channel L2.

[0064] The arrangement that the flow channel, the heating element channel S and the ironing panel 1 are located on the same die-cast aluminum part not only improves the compactness of the structure and makes processing and assembly more convenient, but also improves the heat transfer efficiency, reduces heat loss, and heats up quickly, so that water can be quickly heated into steam.

[0065] like Figure 4 , 6 As shown, the heating element channel S forms a bulge U on the bottom wall of the steam cavity C, and the bulge U is located in the first flow channel L1 and the second flow channel L2. This structure increases the heat exchange area between water and the heating element 22, more effectively utilizes the heating element 22, and improves thermal efficiency.

[0066] like Figure 1 , 6 As shown, the water flow direction of the flow channel is a spiral direction from outside to inside. The lower wall of the shell 21, that is, the ironing panel 1 in this embodiment, is provided with two steam outlet hole groups Y parallel to each other, and each steam outlet hole group Y is composed of multiple steam outlet hole groups Y and corresponds to the first flow channel L1 or the second flow channel L2 respectively. As shown in the figure, the ironing panel is provided with multiple circles of annular steam guide grooves m surrounding the steam outlet hole group Y, and multiple steam retention hole grooves t are provided in the annular steam guide grooves m.

[0067] like Figure 6 As shown, each steam outlet group Y is located between the ridge formed by the end isolation wall q and the heating element channel S, so that more heat can be stored there, so that when water flows to this part, it is heated as quickly as possible and turned into steam and sprayed out quickly.

[0068] like Figure 3 , 6As shown, the upper wall of the shell is provided with a receiving groove H which is concave downward from the upper surface, and the two sides of the side groove wall of the receiving groove H form the partial flow channel walls of the first flow channel L1 and the second flow channel L2, and the temperature sensor 400 is provided in the receiving groove H. That is, in this embodiment, the upper shell 21a has a through hole, and the lower shell 21b is provided with a receiving groove H, and the two sides of the side groove wall of the receiving groove H form the partial flow channel walls of the first flow channel L1 and the second flow channel L2, and the groove wall of the receiving groove H passes through the upper shell 21a to form a concave position which is concave downward from the upper surface, and the temperature sensor 400 is provided in the concave position. Through this arrangement, the temperature sensor 400 is immersed in the area surrounded by the flow channel, thereby improving the accuracy of temperature detection.

[0069] Of course, the temperature sensor 400 can also be a temperature control device that also has a temperature control function. When in use, the temperature control is first started. When the heating element 22 is heated to a specific temperature, the temperature control is automatically turned off, and the water pump is turned on to pump water into the steam cavity C. After the heating element 22 cools down, the temperature control is automatically turned on. The cycle is repeated, the heating element 22 works, and the water in the flow channel forms steam.

[0070] like Figure 5 , 7 As shown in Figure 9, the water inlet interface 2 extends from the through hole of the upper shell 21a into the steam cavity C, and then is sealed and fixedly connected to the upper shell 21a through liquid heat-resistant silicone. The back of the water inlet interface 2 is provided with a water inlet column g connected to the water inlet hole k, and the water inlet column g guides water to the corresponding flow channel.

[0071] Further, if Figure 7-9 As shown, an interface groove F is provided in the middle of the water inlet interface 2, and a central and concave collecting groove W is provided at the bottom of the interface groove F, and two water inlet holes k are respectively located on both sides of the collecting groove W. As shown in the figure, the collecting groove W is olive-shaped with a wide middle and narrow sides. The setting of the collecting groove W is more conducive to water distribution and improves the phenomenon of air and water entrapment.

[0072] The above is a detailed introduction to a dual-flow steam generator and a steam garment steamer applicable thereto provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the present invention and its core ideas. It should be pointed out that for ordinary technicians in this technical field, the present invention can also be improved and modified in a number of ways without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
