Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a heat dissipation structure and an ironing machine. Background Technology

[0002] An iron is a household appliance used to smooth out clothing and fabrics. It softens the fabric fibers and removes wrinkles by heating the fabric at high temperatures. The control unit (usually a PCB board) is the core component of the iron, responsible for coordinating the work of other components and enabling precise, intelligent, and safe control of the ironing process.

[0003] The control unit generates a significant amount of heat during prolonged operation. In existing technologies, the heat dissipation of the ironing machine's control unit primarily relies on heat sinks, such as directly attaching them to the surface of power devices like IGBTs (Insulated Gate Bipolar Transistors) to dissipate heat through natural convection.

[0004] However, the air convection speed inside the iron is limited, and the heat cannot be dissipated in time through the heat sink. Utility Model Content

[0005] This application provides a heat dissipation structure and an ironing machine to solve the problem of poor heat dissipation in the control unit of the ironing machine.

[0006] Firstly, the heat dissipation structure provided in this application, used in an ironing machine, includes:

[0007] The heat dissipation component is equipped with a liquid cooling channel. The heat dissipation component is used to contact the control unit of the ironing machine, and one end of the liquid cooling channel is used to connect with the boiler of the ironing machine.

[0008] A water pump is connected to the other end of the liquid cooling channel. The water pump is configured to pump water from the iron's water tank into the liquid cooling channel.

[0009] In this configuration, the heat sink of the heat dissipation structure comes into contact with the control unit, allowing the heat generated by the control unit to be conducted to the heat sink. The two ends of the liquid cooling channel on the heat sink are connected to the boiler and the water pump, respectively. Before entering the boiler, the water in the tank flows through the liquid cooling channel, carrying away heat from the heat sink, and then flows to the boiler. This liquid cooling method for dissipating heat from the control unit is more efficient than the natural convection cooling of heat sinks. Furthermore, the liquid cooling channel is connected in series between the boiler and the water tank of the ironing machine, allowing them to share a single water pump. This eliminates the need for a separate pump and channel for the heat sink, resulting in a simpler overall structure and smaller footprint.

[0010] In one possible implementation, the heat dissipation structure provided in this application further includes a heat-conducting element disposed on the heat dissipation element and used to abut against the control unit.

[0011] Thus, by placing a heat-conducting component between the heat sink and the control unit, the heat conduction efficiency is improved, thereby enhancing the heat dissipation effect on the control unit.

[0012] In one possible implementation, the heat dissipation structure provided in this application further includes an insulating component disposed between the heat-conducting component and the heat dissipation component.

[0013] In this way, the insulating component blocks the current through its high insulation resistance, ensuring electrical isolation between the heat sink and the control unit, and avoiding short circuits, leakage and other phenomena.

[0014] In one possible implementation, the heat dissipation structure provided in this application further includes a first connecting pipe and a second connecting pipe. The first connecting pipe connects the liquid cooling channel to the outlet of the water pump, and the second connecting pipe connects the inlet of the water pump to the water tank of the iron.

[0015] Thus, when the water pump is working, the water in the tank enters the water inlet of the water pump through the second connecting pipe, and then flows through the water outlet of the water pump, the first connecting pipe, the liquid cooling channel on the heat dissipation component, and finally flows to the boiler.

[0016] In one possible implementation, the heat dissipation structure provided in this application further includes a third connecting pipe, which is installed inside the water tank of the ironing machine and is connected to the second connecting pipe.

[0017] Thus, by setting a third connecting pipe, with the end of the third connecting pipe away from the second connecting pipe abutting against the bottom of the water tank, the water pump can continuously pump water from the water tank into the liquid cooling channel even if the liquid level in the water tank is low, thus avoiding interruption of liquid supply.

[0018] In one possible implementation, the heat dissipation structure provided in this application further includes a bracket, the bracket having a mounting groove for mounting the control unit of the ironing machine, and the bracket having at least one clearance hole communicating with the mounting groove.

[0019] The heat sink is installed in the mounting slot, and the two ends of the liquid cooling channel extend out of the mounting slot through clearance holes.

[0020] Thus, the bracket serves to support and carry the control unit and the heat sink, securing them firmly within the housing of the ironing machine body. The heat sink is positioned between the control unit and the bracket. One end of the liquid cooling channel on the heat sink is connected to the water pump via a clearance hole, and the other end of the liquid cooling channel is also connected to the boiler via a clearance hole.

[0021] In one possible implementation, the heat dissipation structure provided in this application includes a heat dissipation part and a pipe part, the pipe part being disposed on the heat dissipation part, and the heat dissipation part being used to abut against the control unit of the ironing machine.

[0022] The liquid cooling channel is located on the pipe section, which has an inlet and an outlet that are respectively connected to the liquid cooling channel. The inlet is connected to the water pump through a clearance hole, and the outlet is connected to the boiler of the ironing machine through the clearance hole.

[0023] In this way, the heat generated by the control unit can be conducted to the heat dissipation unit. Water in the water tank, under the action of the water pump, enters the liquid cooling channel through the inlet of the pipe section, absorbs the heat from the heat dissipation unit, and then flows to the boiler through the outlet of the pipe section.

[0024] In one possible implementation, the heat dissipation structure provided in this application has a limiting groove in the mounting groove, the end of the limiting groove extending in the direction of extension is connected to the clearance hole, and the pipe part is disposed in the limiting groove.

[0025] In this way, the limiting groove can play a role in positioning and installing the pipe section, and the limiting groove can form radial and axial constraints on the pipe section to restrict the movement of the heat dissipation component relative to the bracket, thereby preventing the heat dissipation component from swinging or shaking when the ironing machine is performing ironing work.

[0026] In one possible implementation, the heat dissipation structure provided in this application has at least one first limiting part in the mounting groove. The first limiting part has a support section and a limiting section connected to each other. The support section is located at the edge of the limiting groove, and the limiting section extends into the limiting groove.

[0027] The heat dissipation section abuts against the support section, and the limiting section abuts against the pipe section inside the limiting groove.

[0028] Thus, the limiting section of the first limiting part extends into the limiting groove and abuts against the pipe part. This allows the limiting section to press and compress the pipe part, confining it within the limiting groove and preventing it from falling out. Furthermore, the limiting section of the first limiting part abuts against the heat dissipation part, and the contact area between the limiting section and the heat dissipation part is small. This prevents most of the heat from the heat dissipation part from being conducted to the bracket, thus avoiding poor heat dissipation.

[0029] Secondly, the ironing machine provided in this application includes:

[0030] The ironing machine body;

[0031] The control unit is located on the ironing machine body;

[0032] The boiler is mounted on the ironing machine body and is electrically connected to the control unit. The boiler is used to generate high-temperature steam.

[0033] Water tank, which is located on the main body of the ironing machine;

[0034] Any of the above heat dissipation structures are installed on the ironing machine body, the heat dissipation components of the heat dissipation structure are in contact with the control unit, and the water pump of the heat dissipation structure is connected to the water tank.

[0059] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0060] In related technologies, the control unit of an ironing machine generates a large amount of heat during prolonged operation. Existing technologies primarily rely on heat sinks for heat dissipation in the control unit, such as directly attaching heat sinks to the surface of power devices like IGBTs (Insulated Gate Bipolar Transistors) to dissipate heat through natural convection.

[0061] However, the air convection speed inside the iron is limited, and the heat cannot be dissipated in time through the heat sink.

[0062] In view of the above problems, this application provides a heat dissipation structure and an ironing machine. The heat dissipation structure includes a heat sink and a water pump. The heat sink has a liquid cooling channel and is used to contact the control unit of the ironing machine. One end of the liquid cooling channel is connected to the boiler of the ironing machine. The water pump is connected to the other end of the liquid cooling channel and is configured to pump water from the water tank of the ironing machine into the liquid cooling channel. The heat generated by the control unit can be conducted to the heat sink. The two ends of the liquid cooling channel on the heat sink are connected to the boiler and the water pump, respectively. Before entering the boiler, the water in the water tank flows through the liquid cooling channel, carrying away the heat from the heat sink, and then flows to the boiler. In this way, the control unit is cooled by liquid cooling, resulting in high heat dissipation efficiency. Furthermore, the liquid cooling channel is connected in series between the boiler and the water tank of the ironing machine, allowing a single water pump to be used, eliminating the need for a separate water pump and channel for the heat sink. This results in a simple overall structure and a small footprint.

[0063] To facilitate understanding, the application scenarios of the embodiments of this application will be described first.

[0064] The ironing machine provided in this application embodiment can be applied to clothing manufacturing, storage, sales, or laundry shops. The clothing to be ironed by the ironing machine should be interpreted broadly, including but not limited to clothes, trousers, and other items for wearing, as well as fabrics such as curtains, sheets, and duvet covers. This application embodiment does not specifically limit this, and will be collectively referred to as "clothing" below, without further specific examples.

[0065] The following describes in detail, with reference to the accompanying drawings, the heat dissipation structure provided in the embodiments of this application and the specific implementation of the ironing machine.

[0066] Reference Figures 1 to 7 As shown in the embodiment of this application, the heat dissipation structure 10 is used in an ironing machine and includes a heat sink 200 and a water pump 300.

[0067] The heat sink 200 is provided with a liquid cooling channel 201. The heat sink 200 is used to abut against the control unit 30 of the ironing machine. One end of the liquid cooling channel 201 is used to connect with the boiler of the ironing machine. The water pump 300 is connected to the other end of the liquid cooling channel 201. The water pump 300 is configured to pump water from the water tank 40 of the ironing machine into the liquid cooling channel 201.

[0068] It is understood that the heat dissipation structure 10 provided in this application embodiment is applicable to an ironing machine. The ironing machine has an ironing machine body 20, which includes a housing 21 and an ironing panel 22. The ironing panel 22 is connected to the housing 21 to form a receiving cavity, and a boiler is disposed in the receiving cavity. The boiler is connected to the ironing panel 22. The ironing machine also includes a water tank 40, which is connected to the housing 21. The water pump 300 in the heat dissipation structure 10 is connected to the water tank 40 and the boiler.

[0069] When ironing clothes, the user can hold the housing 21 and press the ironing panel 22 against the clothes. The water pump 300 then pumps water from the iron's water tank 40 into the boiler, where it is heated to generate high-temperature steam. The high-temperature steam is then sprayed onto the clothes through the steam holes on the ironing panel 22, thus steam ironing the clothes.

[0070] The cavity also houses a control unit 30, to which the boiler's heating elements (e.g., heating wires), water pump 300, and other electrical components are electrically connected, allowing the control unit 30 to control the operation of these components. For example, the control unit 30 uses a PCB (Printed Circuit Board) as its carrier, integrating components such as temperature sensors (e.g., NTC thermistors), temperature control chips, and relays.

[0071] Reference Figure 2 As shown, the heat sink 200 of the heat dissipation structure 10 abuts against the control unit 30, and the heat generated by the control unit 30 during operation can be conducted to the heat sink 200. The two ends of the liquid cooling channel 201 on the heat sink 200 are connected to the boiler and the water pump 300, respectively. Before the water in the water tank 40 enters the boiler, it first flows through the liquid cooling channel 201, carrying away the heat from the heat sink 200, and then flows to the boiler. In this way, the control unit 30 is cooled by liquid cooling, which is more efficient than the natural convection cooling of heat sinks.

[0072] Furthermore, after absorbing heat from the heat dissipation component 200, the water temperature rises, which is equivalent to preheating the water before it enters the boiler, reducing the temperature difference between the water and the boiler's internal temperature. This allows the water temperature to rise steadily and slowly, greatly reducing thermal shock and fatigue damage to the boiler's metal components, thereby effectively extending the boiler's service life. Simultaneously, it also improves the boiler's steam generation efficiency and reduces energy consumption.

[0073] Reference Figure 2 As shown, the liquid cooling channel 201 is connected in series between the boiler and the water tank 40 of the ironing machine, so that a single water pump 300 can be used. This eliminates the need to configure a separate water pump 300 and channel for the heat dissipation component 200, resulting in a simple overall structure and small space occupation.

[0074] Reference Figure 2 and Figure 3 As shown, in some embodiments, the heat dissipation structure 10 provided in this application embodiment further includes a heat-conducting element 500, which is disposed on the heat dissipation element 200 and is used to abut against the control unit 30.

[0075] In the above embodiment, by providing a heat-conducting component 500 between the heat sink 200 and the control unit 30, the heat conduction efficiency is improved, thereby enhancing the heat dissipation effect on the control unit 30.

[0076] For example, the thermal conductive component 500 can be a thermally conductive silicone pad. The thermally conductive silicone pad can fill the gap between the heat sink 200 and the control unit 30 through its own deformation to ensure a larger contact area, thereby improving the heat dissipation effect. The thermal conductive component 500 can also be thermal grease, a metal thermal pad, a thermal gel, etc., without specific limitations.

[0077] Reference Figure 2 and Figure 3 As shown, in some embodiments, the heat dissipation structure 10 provided in this application embodiment further includes an insulating member 600, which is disposed between the heat-conducting member 500 and the heat dissipation member 200.

[0078] In the above embodiment, the insulating component 600 blocks the current through its own high insulation resistance, ensuring electrical isolation between the heat sink 200 and the control unit 30, and avoiding short circuits, leakage and other phenomena.

[0079] The heat sink 200 can be made of metal, which has excellent thermal conductivity, to ensure effective heat dissipation for the control unit 30. An insulating component 600 is included to prevent short circuits.

[0080] For example, the insulating component 600 can be an insulating silicone sheet, an insulating coating (such as a ceramic coating, an organosilicon insulating varnish), etc., and the embodiments of this application do not impose specific limitations on it.

[0081] Reference Figure 2 and Figure 4 As shown, in some embodiments, the heat dissipation structure 10 provided in this application further includes a first connecting pipe 410 and a second connecting pipe 420. The first connecting pipe 410 connects the liquid cooling channel 201 to the water outlet 320 of the water pump 300, and the second connecting pipe 420 connects the water inlet 310 of the water pump 300 to the water tank 40 of the ironing machine.

[0082] In the above embodiment, when the water pump 300 is working, the water in the water tank 40 enters the water inlet 310 of the water pump 300 through the second connecting pipe 420, and then flows sequentially through the water outlet 320 of the water pump 300, the first connecting pipe 410, the liquid cooling channel 201 on the heat sink 200, and finally flows to the boiler.

[0083] In this way, by setting the first connecting pipe 410 and the second connecting pipe 420 to form a flow channel system, the water in the water tank 40 can be pumped sequentially into the liquid cooling flow channel 201 and the boiler by the water pump 300.

[0084] For example, the first connecting tube 410 and the second connecting tube 420 can both be flexible hoses. Flexible hoses are lightweight and flexible, making it easy to thread and connect them in the receiving cavity of the iron.

[0085] Reference Figure 4 As shown, the water tank 40 of the ironing machine includes a water tank body 41 and a water tank cover 42. The water tank cover 42 is disposed on the water tank body 41 to form a water storage cavity. The edges of the water tank body 41 and the water tank cover 42 can be fixed by welding, which ensures a stable connection and eliminates the need for additional sealing components.

[0086] The water tank cover 42 can be detachably connected to the housing 21 of the ironing machine body 20, for example, through a bolt structure or a snap-fit ​​structure, so as to facilitate assembly and disassembly.

[0087] Furthermore, the water tank cover 42 is provided with a liquid inlet communicating with the water storage chamber for adding water to the water storage chamber. The liquid inlet can be sealed with a sealing cap. The water tank cover 42 is also provided with a liquid outlet channel 421 communicating with the water storage chamber. The end of the second connecting pipe 420 away from the water pump 300 can be sleeved on the outside of the liquid outlet channel 421.

[0088] Reference Figure 4 As shown, in some embodiments, the heat dissipation structure 10 provided in this application embodiment further includes a third connecting pipe 430, which is used to be disposed in the water tank 40 of the ironing machine, and the third connecting pipe 430 is connected to the second connecting pipe 420.

[0089] In the above embodiment, by setting a third connecting pipe 430, the end of the third connecting pipe 430 away from the second connecting pipe 420 is in contact with the bottom of the water tank 40, so that even if the liquid level in the water tank 40 is low, the water pump 300 can continuously pump the water pump 300 in the water tank 40 into the liquid cooling channel 201, thus avoiding interruption of liquid supply.

[0090] For example, the third connecting pipe 430 is a flexible hose that can be bent and deformed, so that no matter whether the water tank 40 is in an upright or tilted state, the end of the third connecting pipe 430 away from the second connecting pipe 420 is always below the liquid level.

[0091] Furthermore, the third connecting pipe 430 can be sleeved on the outside of the liquid outlet channel 421 on the water tank cover 42, so that the second connecting pipe 420 and the third connecting pipe 430 can be connected through the liquid outlet channel 421.

[0092] Reference Figures 5 to 7As shown, in some embodiments, the heat dissipation structure 10 provided in this application further includes a bracket 100. The bracket 100 has a mounting groove 110 for mounting the control unit 30 of the ironing machine. The bracket 100 has at least one clearance hole 120 communicating with the mounting groove 110. The heat dissipation component 200 is disposed in the mounting groove 110, and both ends of the liquid cooling channel 201 extend out of the mounting groove 110 through the clearance hole 120.

[0093] The bracket 100 can be installed into the receiving cavity of the ironing machine body 20.

[0094] In the above embodiment, the bracket 100 serves to support the control unit 30 and the heat sink 200, so as to securely install them in the receiving cavity of the ironing machine body 20. The heat sink 200 is disposed between the control unit 30 and the bracket 100. One end of the liquid cooling channel 201 on the heat sink 200 is connected to the water pump 300 through the clearance hole 120, and the other end of the liquid cooling channel 201 is also connected to the boiler through the clearance hole 120.

[0095] Reference Figure 7 As shown, the bracket 100 is provided with at least one second limiting part, which is disposed on the edge of the mounting groove 110. The second limiting part abuts against the control unit 30 to limit the control unit 30 within the mounting groove 110 of the bracket 100.

[0096] For example, the second limiting part can be a snap-fit ​​element. There are two second limiting parts, which are disposed opposite to each other on both sides of the mounting groove 110.

[0097] Reference Figure 3 and Figure 5 As shown, in some embodiments, the heat sink 200 includes a heat sink 210 and a pipe section 220. The pipe section 220 is disposed on the heat sink 210 and is used to abut against the control unit 30 of the ironing machine. A liquid cooling channel 201 is disposed on the pipe section 220. The pipe section 220 has an inlet 221 and an outlet 222 that are respectively connected to the liquid cooling channel 201. The inlet 221 is connected to the water pump 300 through a clearance hole 120, and the outlet 222 is used to connect to the boiler of the ironing machine through the clearance hole 120.

[0098] In the above embodiment, the heat generated by the control unit 30 can be conducted to the heat dissipation unit 210. Under the action of the water pump 300, the water in the water tank 40 enters the liquid cooling channel 201 through the water inlet 221 of the pipe section 220, absorbs the heat on the heat dissipation unit 210, and then flows to the boiler through the water outlet 222 of the pipe section 220.

[0099] Among them, reference Figure 3As shown, the heat dissipation part 210 can be a plate-shaped structure. The side of the heat dissipation part 210 with a larger area is used to abut against the control unit 30, which can increase the contact area with the control unit 30 and improve the heat dissipation efficiency.

[0100] Furthermore, the pipe portion 220 is curved (e.g., S-shaped, Z-shaped, W-shaped, etc.) and located on the side with the larger area of ​​the heat dissipation portion 210. This extends the length of the liquid cooling channel 201 and increases the contact area with the heat dissipation portion 210, thereby ensuring heat dissipation. For example, the pipe portion 220 and the heat dissipation portion 210 can be fixed by welding or by stamping, allowing them to be installed as a single unit, simplifying subsequent installation steps.

[0101] Reference Figure 3 As shown, the pipe section 220, heat dissipation section 210, insulating component 600, heat-conducting component 500, and control unit 30 are arranged sequentially from the bottom of the mounting groove 110 outwards. The inlet 221 and outlet 222 of the pipe section 220 extend out of the mounting groove 110 through the clearance hole 120 on the bracket 100. In this way, the mounting space on the bracket 100 is fully utilized, and the overall structure is more compact.

[0102] Reference Figures 5 to 7 As shown, in some embodiments, a limiting groove 130 is provided in the mounting groove 110, the end of the limiting groove 130 extending in the direction of the limiting groove 130 is connected to the clearance hole 120, and the pipe part 220 is provided in the limiting groove 130.

[0103] In the above embodiment, the limiting groove 130 can be used to position and install the pipe section 220, and the limiting groove 130 can form radial and axial constraints on the pipe section 220 to restrict the movement of the heat sink 200 as a whole relative to the bracket 100, thereby preventing the heat sink 200 from swinging or shaking when the ironing machine is performing ironing work.

[0104] Furthermore, the end of the limiting groove 130 extending in the direction of extension is connected to the clearance hole 120, so that the inlet 221 and outlet 222 of the pipe section 220 can directly enter the clearance hole 120 from the end of the limiting groove 130 extending in the direction of extension.

[0105] Reference Figure 5 and Figure 7 As shown, the limiting groove 130 can be an arc-shaped groove to adapt to the shape of the pipe section 220.

[0106] Reference Figure 7As shown, in some embodiments, at least one first limiting portion 140 is provided in the mounting groove 110. The first limiting portion 140 has a supporting section 141 and a limiting section 142 connected to each other. The supporting section 141 is located at the edge of the limiting groove 130, and the limiting section 142 extends into the limiting groove 130. The heat dissipation portion 210 abuts against the supporting section 141, and the limiting section 142 abuts against the pipe portion 220 in the limiting groove 130.

[0107] In the above embodiment, the limiting segment 142 of the first limiting part 140 extends into the limiting groove 130 and abuts against the pipe part 220. This allows the limiting segment 142 to press and compress the pipe part 220, confining it within the limiting groove 130 and preventing it from falling out. Furthermore, the limiting segment 142 of the first limiting part 140 abuts against the heat dissipation part 210, and the contact area between the limiting segment 142 and the heat dissipation part 210 is small. This prevents most of the heat from the heat dissipation part 210 from being conducted to the bracket 100, thus avoiding poor heat dissipation.

[0108] Specifically, refer to Figure 7 As shown, there can be multiple first limiting parts 140. The first limiting parts 140 are spaced apart along the periphery of the limiting groove 130, and the first limiting parts 140 are provided on both sides of the extending direction of the limiting groove 130. This ensures that the limiting section 142 of the first limiting part 140 has a tight limiting effect on the pipe part 220 as a whole, and that the supporting section 141 of the first limiting part 140 has a supporting effect on the heat dissipation part 210.

[0109] Reference Figure 1 As shown, the ironing machine provided in this application embodiment includes an ironing machine body 20, a control unit 30, a boiler, a water tank 40, and a heat dissipation structure 10 as in any of the above embodiments.

[0110] The control unit 30 is mounted on the ironing machine body 20, and the boiler is mounted on the ironing machine body 20. The boiler is electrically connected to the control unit 30 and is used to generate high-temperature steam. The water tank 40 is mounted on the ironing machine body 20, and the heat dissipation structure 10 is mounted on the ironing machine body 20. The heat dissipation component 200 of the heat dissipation structure 10 abuts against the control unit 30, and the water pump 300 of the heat dissipation structure 10 is connected to the water tank 40.

[0111] Since the ironing machine adopts the heat dissipation structure 10 in the above embodiment, it also has the advantages and benefits brought by the heat dissipation structure 10, which will not be elaborated further here.
