Description

Technical Field

[0001] This utility model relates to clothing ironing appliances, specifically a steam iron that uses suction to assist ironing. Background Technology

[0002] When using a garment steamer, the released steam can blow clothes away from the work surface, hindering the steam from reaching the work surface for proper ironing. Using a suction fan to draw the clothes towards the work surface during ironing can overcome this drawback. However, the suction fan in existing handheld garment steamers is often located too far from the suction port on the work surface, resulting in weak suction and significant noise. Utility Model Content

[0003] This invention addresses the shortcomings of existing irons that use a fan to draw clothes onto the work surface, such as weak suction and high noise. It provides a steam iron with strong suction and low noise, which uses suction to assist ironing.

[0004] To achieve the above objectives, the steam iron of this invention, which uses suction to assist ironing, is characterized by comprising: The head housing is equipped with ventilation holes; A vaporization device, located inside the head housing, is used to vaporize water into steam; The working surface is assembled at the front end of the head shell. The working surface is equipped with steam holes and suction holes. The steam holes are used to release steam from the vaporization device, and the suction holes are used to adsorb clothes onto the working surface by suction. The suction fan is located inside the head housing. When the suction fan is working, it draws in air through the suction port and exhausts air through the exhaust port. The vaporization device is located above the suction fan.

[0005] This steam iron uses a vaporization device positioned above the suction fan, which shortens the distance between the suction fan and the suction holes on the work surface, resulting in strong suction and low noise.

[0006] To ensure ease of use and reduce user strain, handheld garment steamers should not be too large. This limits their size and flexibility. Consequently, the included suction fan is also designed for internal installation and cannot be too bulky. This steam iron balances fan size and suction power while maintaining a compact design and small size.

[0007] Preferably, the head housing has an air distribution chamber located on the back side of the working surface, through which the suction fan draws air from the suction holes during operation. This ensures that each suction hole applies a consistent suction force to the clothing.

[0008] Preferably, the steam holes are located in the middle of the working surface, and the suction holes are distributed around the steam holes, with the air distribution chamber arranged in a ring corresponding to the suction holes. Accordingly, during ironing, the clothes are drawn to the working surface by suction and covered by the clothes, preventing gaps between the clothes and the working surface from causing steam overflow. This ensures that all the steam is applied to the clothes for ironing, guaranteeing the ironing effect.

[0009] Because the suction fan easily draws in steam, which readily condenses into water droplets, the head housing has an exhaust duct. During operation, the suction fan exhausts air through this duct to the exhaust port. This prevents water droplets from condensing inside the head housing from damaging the suction fan.

[0010] Preferably, the vaporization device extends forward to the working face or forms part of the working face. This shortens the path of the steam output from the vaporization device and reduces steam leakage within the head casing.

[0011] Preferably, the vents face the left and right sides of the head housing to avoid blowing air directly onto the user and causing discomfort.

[0012] Preferably, the head housing is wider at the top and narrower at the bottom. Based on the structure where the vaporization device is located above the suction fan, this is suitable for configuring a larger vaporization device and a smaller suction fan. The larger vaporization device has a greater vaporization capacity, while the smaller suction fan, based on its position, ensures its suction capacity. This thus ensures a compact head housing structure and a suitable overall volume profile.

[0013] Preferably, the head housing is wider at the front and narrower at the rear. Based on the structure where the vaporization device is located above the suction fan, this is suitable for configuring a longer vaporization device and a shorter suction fan in the front-to-back direction. This ensures a compact head housing structure and a suitable overall volume profile.

[0014] Preferably, a heat insulation structure is provided between the vaporization device and the suction fan. This prevents heat transfer (especially radiation) from the vaporization device to the suction fan, which would reduce the lifespan of the suction fan.

[0015] Preferably, the heat insulation structure is a heat shield disposed on the outside of the vaporization device. This further shields the heat from the vaporization device, reducing radiation and conduction to the head shell.

[0016] This invention uses a vaporization device positioned above the suction fan to shorten the distance between the suction fan and the suction holes on the working surface, resulting in strong suction and low noise.

[0017] This invention limits the suction fan to be suitable for installation in a handheld garment steamer, which takes into account both the size and suction power of the fan, and also makes the product structure compact and small in size. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this utility model are intended to cover non-exclusive inclusion, such as a method or product that includes a series of technical features, not limited to those technical features explicitly listed, but also including other technical features that may be included in the method or product but not explicitly listed.

[0021] In the description of this utility model, it should be understood that the technical features defined by terms such as "first" and "second" which have a sequential concept are only for the purpose of clearly describing the defined technical features and making the defined technical features clearly distinguishable from other technical features, and do not represent that they are named in this way in actual implementation. Therefore, they should not be construed as limitations on this utility model.

[0022] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0023] Example 1 Figure 1-5 A steam ironing device that uses suction to assist ironing is shown. The steam ironing device includes a head housing 100, a vaporization device 200, a working surface 300, and a suction fan 400.

[0024] The head housing 100 is equipped with an exhaust vent 101.

[0025] The vaporization device 200 is located inside the head housing 100 and is used to vaporize water into steam.

[0026] The working surface 300 is mounted on the front end of the head housing 100 and is used to face or even contact the clothing during ironing. The ironing surface faces forward. The working surface 300 is provided with steam holes 301 and suction holes 302. The steam holes 301 are used to release steam from the vaporization device, and the suction holes 302 are used to draw the clothing onto the working surface by suction.

[0027] The suction fan 400 is located inside the head housing 100. When the suction fan 400 is working, it draws in air through the suction port 302 and exhausts air through the exhaust port 101.

[0028] The vaporization device 200 is located above the suction fan 400, which shortens the distance between the suction fan 400 and the suction hole 302 on the working surface 300, resulting in strong suction and low noise.

[0029] To ensure ease of use and reduce user strain, handheld garment steamers should not be too large. This limits their size and flexibility. Consequently, the included suction fan is also designed for internal installation and cannot be too bulky. This steam iron balances fan size and suction power while maintaining a compact design and small size.

[0030] In this embodiment, the suction fan 400 is a centrifugal fan. For example... Figure 4 As shown, the centrifugal fan includes a suction chamber 450 located in front of the motor 410. The suction chamber 450 has an axial suction port 451 and a radial air outlet. The airflow drive component 420 is a centrifugal impeller 422 located in the suction chamber 450. When the centrifugal impeller 422 rotates, it draws airflow into the suction chamber 450 through the axial suction port 451 and discharges airflow from the suction chamber 450 through the radial air outlet. Figure 4 In the diagram, dashed lines with arrows indicate the direction of airflow. Centrifugal fans have strong suction, which helps to adhere clothing to the work surface.

[0031] Moreover, such as Figure 4 As shown, the centrifugal impeller 422 and the motor 410 are magnetically driven. The motor 410 has a first magnetic drive part 414, and the centrifugal impeller 422 has a second magnetic drive part 423. The first magnetic drive part 414 and the second magnetic drive part 423 are axially aligned and isolated by the wall 452 of the suction chamber. This structure eliminates the need for the motor shaft to pass through the wall of the suction chamber, completely isolating the motor and the centrifugal impeller, eliminating leakage points, preventing steam from leaking into and corroding the motor during suction, and extending the motor's lifespan.

[0032] Alternatively, the magnetic drive between the centrifugal impeller 422 and the motor 410 can be replaced with, for example... Figure 5 The centrifugal impeller 422 shown is mounted on the output shaft 411 of the motor, and the output shaft extends through the wall 452 of the suction chamber to the suction chamber 450. The transmission structure is simple, reliable, and has a long service life. Figure 5 In the diagram, the direction of airflow is indicated by a dashed line marked with an arrow.

[0033] In this embodiment, the head housing has an air distribution chamber located on the back side of the working surface. When the suction fan is working, it draws air through the air distribution chamber from the air intake holes, ensuring that each air intake hole can exert a consistent suction force on the clothing.

[0034] like Figure 1-3 As shown, the steam vent 301 is located in the middle of the working surface 300, and the suction vents 302 are distributed around the steam vent 301. The air distribution chamber 102 is arranged in a ring corresponding to the suction vents 302. Accordingly, during ironing, the clothes are drawn to the working surface by suction and covered by the clothes, avoiding the formation of gaps between the clothes and the working surface that would cause steam to overflow. This ensures that all the steam is applied to the clothes for ironing, guaranteeing the ironing effect.

[0035] Because the suction fan easily draws in steam during operation, and the steam readily condenses into water droplets, the head housing 100 has an exhaust channel 103. When the suction fan 400 is working, it exhausts air through the exhaust channel 103 to the exhaust port 101, preventing water droplets from condensing and remaining inside the head housing, which could damage the suction fan. This exhaust channel 103 is described in Embodiment 2. Figure 7 It is shown in detail in the text.

[0036] In this embodiment, the vaporization device 200 extends forward to the working surface 300 and connects with the steam port 301. This shortens the path of the steam output from the vaporization device and reduces steam leakage within the head casing.

[0037] Furthermore, such as Figure 2 As shown, the vent 101 faces the left and right sides of the head housing 100. This is to prevent the air from blowing directly onto the user and causing discomfort.

[0038] like Figure 1-2 As shown, the head housing 100 is wider at the top and narrower at the bottom. Based on the structure where the vaporization device 200 is located above the suction fan 400, this is suitable for arranging a larger vaporization device and a smaller suction fan. The larger vaporization device has a greater vaporization capacity, while the smaller suction fan, based on its position, ensures its suction capacity. This ensures a compact head housing structure and a suitable overall volume profile. Furthermore, the head housing 100 is wider at the front and narrower at the rear. Based on the structure where the vaporization device is located above the suction fan, this is suitable for arranging a longer vaporization device and a shorter suction fan in the longitudinal direction. This again ensures a compact head housing structure and a suitable overall volume profile.

[0039] like Figure 3 As shown, a heat insulation structure is provided between the vaporization device 200 and the suction fan 400. This prevents heat transfer (especially radiation) from the vaporization device to the suction fan, which would reduce the lifespan of the suction fan. Specifically, the heat insulation structure is a heat shield 201 located outside the vaporization device 200. This further shields the heat from the vaporization device, reducing radiation and conduction to the head housing.

[0040] In this embodiment, a handle 500 for gripping extends downward from the head housing 100, and the lower end of the handle 500 is connected to a seat 600, through which the steam iron can be placed on the platform. In other embodiments, the seat may be omitted; for example, in garment steamers, a semi-circular placement position with an opening is typically provided for the steam iron, within which the handle can be placed.

[0041] Example 2 Figure 6-8 Another steam ironing device that uses suction to assist ironing is shown. This steam ironing device differs from Example 1 in the following ways.

[0042] First, in this embodiment, the suction fan 400 is an axial flow fan.

[0043] like Figure 8As shown, the axial flow fan includes an annular duct 430 defined between an inner annular wall 431 and an outer annular wall 432 extending axially (in the extension direction of the output shaft 411), and the airflow drive 420 is an axial flow fan 421, which corresponds to the first end of the annular duct 430. Figure 8 The right end (as shown) is used to draw airflow in from the first end of the annular duct and out from the second end of the annular duct during rotation. Figure 8 (As shown on the left) is discharged. Axial flow fans can generate a large air volume, which is beneficial for adsorbing clothing onto the work surface.

[0044] In this embodiment, the output shaft 411 is rotatably mounted in the inner ring wall 431 via two bearings 412, and the two bearings 412 are isolated by the isolation sleeve 413 fitted on the output shaft.

[0045] In particular, the motor 410 is located at the second end of the annular air duct 430 and avoids the annular air duct and its extension path. The extension path of the annular air duct is the direction in which the airflow continues to flow after exiting the annular air duct. Figure 8 In the diagram, the direction of airflow is indicated by a dotted line marked with an arrow. During operation, even if steam is drawn in, the fan motor will not be exposed to the steam-laden airflow, thus preventing a reduction in motor lifespan. Instead, the motor remains in its normal operating environment, ensuring its longevity. Furthermore, there is no need to wrap the motor with a waterproof sealing layer, which facilitates heat dissipation and extends motor life.

[0046] Furthermore, the motor 410 is fitted with an annular guide shroud 440. The first end of the annular guide shroud 440 is sealed to the inner annular wall 431, defining the annular air duct 430 and its extension path radially outside the annular guide shroud 440. Accordingly, the annular guide shroud 440 guides the airflow and isolates the airflow from the motor, preventing the motor from operating in a humid environment. The inner annular wall 431 and the outer annular wall 432 are connected by guide vanes 433 located within the annular air duct. The guide vanes 433 are inclined to guide the airflow within the annular air duct, and the inclination of the guide vanes ensures that the extension surface of the guide vanes maintains an angle with the axis. The guide vanes maintain the positional relationship between the inner and outer annular walls and guide the airflow generated by the impeller to flow smoothly through the annular air duct.

[0047] Secondly, in this embodiment, the vaporization device 200 extends forward to form part of the working surface 200, that is, the steam hole 301 is formed at the front end of the vaporization device 200. This is to shorten the path of the steam output from the vaporization device and reduce steam leakage inside the head casing.

[0048] The remaining structure of this embodiment is the same as that of Embodiment 1, and will not be described in detail.
