[0004] The steam generator mentioned above is equipped with an electric heating element (usually a resistance heater). The driving and power control of this electric heating element rely on the drive circuit board of the garment steamer. Therefore, in addition to the main control, interactive module (such as buttons, touch buttons, display screen, indicator lights, etc.) and other necessary peripheral circuits, the drive circuit board of the garment steamer also needs to be equipped with an electric heating element drive module. This electric heating element drive module is mainly based on power electronic devices (such as thyristors, IGBTs or power MOSFETs, etc.) to drive and control the power of the electric heating element.

[0005] However, the aforementioned drive circuit board has a large amount of heat generated by its electric heating device drive module (especially power electronic devices), which affects the user experience, stability and service life of the garment iron, and the large amount of waste heat generated is difficult to be effectively utilized.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This embodiment provides a heat dissipation structure for the drive circuit board components of a garment steamer. It is used in a garment steamer to dissipate heat and recover waste heat for at least one component 11 (especially components with high heat generation such as thyristors, insulated gate bipolar transistors, electric field effect transistors, and control chips) on the drive circuit board of the garment steamer.

[0023] Please see Figures 1-3 The garment steamer in this embodiment includes at least a drive circuit board module 1, a water tank module 3, and a steam generator module 5.

[0024] The garment steamer has an engineering plastic shell, which serves as the mechanical structural support for the drive circuit board module 1, water tank module 3, and steam generator module 5.

[0025] Among them, the drive circuit board module 1 is a printed circuit board (PCB), which is equipped with at least a main control, an interaction module (such as buttons, touch buttons, display screen, indicator lights, etc.) and other necessary peripheral circuits, and is equipped with at least an electric heating device drive module (such as a resistive heater drive module). The electric heating device drive module is mainly composed of power electronic devices such as thyristors, insulated gate bipolar transistors, and electric field-effect transistors.

[0026] The water tank module 3 can store a certain amount of clean water. It can be a separate water tank or a water tank integrated into the outer shell of the garment steamer.

[0027] The steam generator module 5 is a steam generator based on an electric heating device (such as a resistance heater) used to heat water to produce steam.

[0028] The drive circuit board module 1 is electrically connected to at least the heating element of the steam generator module 5 to drive the steam generator module 5 to operate.

[0029] The water tank module 3 is connected to the steam generator module 5 to transport the water stored in the water tank module 3 to the steam generator module 5.

[0030] In order to achieve heat dissipation and waste heat recovery of at least one component 11 on the drive circuit board, the garment steamer also includes a heat dissipation module 2.

[0031] The heat dissipation module 2 can exchange heat with at least one component 11 of the drive circuit board module 1, and the heat dissipation module 2 is connected to the water channel between the water tank module 3 and the steam generator module 5, so that the heat dissipation module 2 can exchange heat with the liquid medium in the water channel.

[0032] It should be noted that the component 11 of the drive circuit board module 1 is specifically at least one of a thyristor, an insulated gate bipolar transistor, a power field-effect transistor, and a control chip; in this embodiment, the component 11 is specifically a thyristor (Silicon Controlled Rectifier, SCR).

[0033] Specifically, the heat dissipation module 2 includes a heat-conducting component 21 and a heat-conducting water pipe component 22. The heat-conducting component 21 is a one-piece molded block metal component with good thermal conductivity (e.g., made of aluminum alloy or copper alloy), and is formed by machining or die casting. The heat-conducting water pipe component 22 is a one-piece molded tubular metal component, which also has good thermal conductivity (e.g., made of aluminum alloy or copper alloy). The heat-conducting component 21 and the heat-conducting water pipe component 22 can exchange heat. The heat-conducting component 21 of the heat dissipation module 2 can exchange heat with at least one component 11 of the drive circuit board module 1. The heat-conducting water pipe component 22 of the heat dissipation module 2 is connected to the water passage between the water tank module 3 and the steam generator module 5, so that the heat dissipation module 2 can exchange heat with the liquid medium in the water passage.

[0034] More specifically, the heat-conducting component 21 of the heat dissipation module 2 includes a substrate portion 211 and a fin portion 212 disposed on the substrate portion 211. In fact, the substrate portion 211 and the fin portion 212 are integrally formed. A heat-absorbing contour groove 212a is formed at the fin portion 212 of the heat-conducting component 21, that is, the heat-absorbing contour groove 212a matches the shape of at least one component 11 of the drive circuit board module 1. At least one component 11 of the drive circuit board module 1 is embedded in the heat-absorbing contour groove 212a of the heat-conducting component 21 and is in contact with the substrate portion 211 and / or the fin portion 212 of the heat-conducting component 21. It can be understood that a thermally conductive medium (e.g., thermally conductive grease) can be coated between at least one component 11 of the drive circuit board module 1 and the substrate portion 211 and / or the fin portion 212 of the heat-conducting component 21. In this way, heat exchange between at least one component 11 of the drive circuit board module 1 and the heat-conducting component 21 is realized.

[0035] More specifically, in some possible embodiments, the heat-conducting water pipe component 22 passes through the fin portion 212 of the heat-conducting component 21, for example, by a through-fin process; or, as... Figure 3 As shown, in some other possible embodiments, a water pipe contour groove 212b is formed at the fin portion 212 of the heat-conducting member 21, that is, the water pipe contour groove 212b matches the shape of the heat-conducting water pipe member 22; the heat-conducting water pipe member 22 is embedded in the water pipe contour groove 212b of the heat-conducting member 21 and is in contact with the substrate portion 211 and / or the fin portion 212 of the heat-conducting member 21; it is understood that a heat-conducting medium (e.g., thermal grease) can be coated between the heat-conducting water pipe member 22 and the substrate portion 211 and / or the fin portion 212 of the heat-conducting member 21; in this way, heat exchange between the heat-conducting water pipe member 22 and the heat-conducting member 21 is achieved.

[0036] More specifically, the garment steamer also includes a water pump module 4, which is a DC-driven water pump capable of driving the directional flow of liquid media. In some possible embodiments, the garment steamer's water tank module 3, water pump module 4, heat dissipation module 2 (heat-conducting water pipe component 22), and steam generator module 5 are sequentially connected by water circuits. In other possible embodiments, the garment steamer's water tank module 3, heat dissipation module 2 (heat-conducting water pipe component 22), water pump module 4, and steam generator module 5 are sequentially connected by water circuits. It is understood that the above-mentioned water circuit connection can be specifically achieved through a flexible water pipe with a quick connector.

[0037] This embodiment also provides a garment steamer, which includes the heat dissipation structure of the drive circuit board components of the garment steamer described above.

[0038] The heat dissipation structure of the drive circuit board components of the garment steamer in this embodiment and the garment steamer using it are described. The heat dissipation module 2 is connected to the water channel between the water tank module 3 and the steam generator module 5. The heat of at least one component 11 of the drive circuit board can be quickly absorbed by the heat dissipation module 2, and the heat dissipation module 2 can exchange heat with the liquid medium in the water channel. On the one hand, it realizes liquid cooling of the drive circuit board and avoids heat accumulation at the heat dissipation module 2, thereby improving the heat dissipation efficiency of the drive circuit board. On the other hand, it can recover the waste heat generated by the components 11 of the drive circuit board and use it by the steam generator module 5, thereby effectively improving the steam generation rate of the garment steamer.
