Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a garment steamer and a main unit thereof. Background Art

[0002] In daily life, people often use steam to iron clothes, remove odors, etc. With the continuous development of technology, steam has gradually been applied to many other aspects, such as baking and cooking food, cleaning the environment, etc.

[0003] Everyday tap water typically contains significant amounts of calcium and magnesium ions. When a steam generator heats water, the pure water turns into steam and is discharged through the steam duct. However, the calcium and magnesium ions in the water are deposited on the surface of the heating element. Over time, this accumulation of calcium and magnesium ions gradually increases, forming a difficult-to-remove scale. This buildup significantly reduces the steam generator's heating efficiency and shortens its lifespan. Furthermore, some of this scale is carried out with the steam, causing pollution and diminishing the user experience. Summary of the Invention

[0004] The main purpose of the present invention is to provide a main unit of a garment steamer, the design of which can not only realize the self-cleaning treatment of the steam generator, but also increase the speed and amount of steam generation, thereby improving the performance of the garment steamer.

[0005] The technical solutions of the present invention are as follows:

[0006] A main unit of a garment steamer comprises a main unit housing and a steam generating device, wherein the steam generating device is installed in the main unit housing and comprises a steam generator and an ultrasonic module, wherein the ultrasonic module is installed outside the steam generator.

[0007] The main unit of the garment steamer is equipped with an ultrasonic module, which is mounted on the outside of the steam generator. The high-frequency vibrations generated by the ultrasonic module can be used to drive the steam generator to vibrate. Once the steam generator is filled with water, the ultrasonic module can be used to effectively remove scale generated inside the steam generator, cleaning the steam generator and giving the main unit of the garment steamer a self-cleaning function. In addition, during the process of the steam generator heating to generate steam, the high-frequency vibrations generated by the ultrasonic module can be used to atomize the water into small droplets. The small droplets are more easily heated and vaporized into steam by the steam generator, thereby increasing the amount and speed of steam generation. In addition, mounting the ultrasonic module on the outside of the steam generator can reduce the impact of the steam generator's heat on the ultrasonic module.

[0008] In some exemplary embodiments, the steam generator has a steam outlet, and the ultrasonic module is installed on a side of the steam generator away from the steam outlet.

[0009] The ultrasonic module is installed on the side of the steam generator away from the steam outlet. The steam outlet is usually set at the upper part of the steam generator, so that the ultrasonic module away from the steam outlet is installed on the lower side of the steam generator. This ensures that the ultrasonic module cleans and descales the steam generator while facilitating the ultrasonic module to fully atomize the water in the steam generator, thereby ensuring the speed of steam generation.

[0010] In some exemplary embodiments, the main unit of the garment steamer further includes a fan, the main unit housing is provided with an air inlet, an air outlet, and an air duct connecting the air inlet and the air outlet, and the fan is located in the air duct; the side of the steam generating device where the ultrasonic module is located extends into the air duct, and the side of the steam generating device where the steam generator is located is located outside the air duct.

[0011] An air duct is provided within the main housing, connecting an air inlet and an air outlet provided on the main housing to form a gas flow path. A fan provided within the air duct generates an airflow when in operation, allowing outside air to enter through the air inlet, flow through the air duct, and finally be discharged through the air outlet. The side of the steam generating device where the ultrasonic module is located extends into the air duct, allowing the ultrasonic module extending into the air duct to be cooled as air flows through the air duct, thereby improving the operational reliability of the ultrasonic module. The side of the steam generating device where the steam generator is located is located outside the air duct to prevent the airflow from cooling or lowering the temperature of the steam generator, thereby enabling the steam generator to maintain a relatively high temperature, facilitating the steam generator's heating of water to produce steam.

[0012] In some exemplary embodiments, a first partition and a first air guide plate are provided in the main body shell, the first air guide plate is located on one side of the first partition, the air duct includes an air guide channel formed between the first partition and the first air guide plate, and the side of the ultrasonic module of the steam generating device where the ultrasonic module is located passes through the first partition and extends into the air guide channel.

[0013] By providing a first partition and a first air guide plate, an air guide channel is formed between the two, and airflow generated by the fan can flow through the air guide channel. The side of the steam generator of the steam generating device is located on the side of the first partition away from the first wind shield, that is, outside the air guide channel. The side of the steam generating device where the ultrasonic module is located passes through the first partition and extends into the air guide channel, allowing airflow to flow through the ultrasonic module, directly and quickly cooling the ultrasonic module, thereby preventing the ultrasonic module from overheating, resulting in low efficiency, poor reliability, and even worse, loss of function.

[0014] In some exemplary embodiments, a second partition and a third partition are further provided in the main body shell, one end of the second partition and the third partition are connected to the first partition, and the other end extends to the side away from the first air guide plate, and a first installation cavity is formed between the first partition, the second partition and the third partition, and the side of the steam generating device where the steam generator is located is installed in the first installation cavity.

[0015] By setting the second partition and the third partition, a first installation cavity is formed between the first partition, the second partition and the third partition. The first installation cavity is isolated from the air guide channel, and the side where the steam generator is located is installed in the first installation cavity to prevent the airflow from cooling and lowering the temperature of the steam generator.

[0016] In some exemplary embodiments, the main housing includes a first side wall and a second side wall arranged opposite to each other, the air inlet is provided on the first side wall, the air outlet is provided on the second side wall, the second partition is close to the first side wall, and the third partition is close to the second side wall. A second air guide plate is also provided in the main housing, one end of the first air guide plate extends to the first side wall, one end of the second air guide plate is connected to the first side wall, and the other end extends toward the second partition, and a first circuit board is provided between the second air guide plate and the second partition, the first circuit board is electrically connected to the ultrasonic module, an air inlet cavity connected to the air inlet is formed between the first air guide plate, the second air guide plate, the first side wall and the first circuit board, and the fan is located in the air inlet cavity; the air duct includes the air inlet cavity, and the air inlet cavity is connected to the air guide channel.

[0017] An air inlet cavity is formed between the first air deflector, the second air deflector, the first sidewall, and the first circuit board. This cavity communicates with the air inlet on the first sidewall, allowing air to enter through the air inlet provided on the first sidewall, pass through the cavity and the air guide channel, and then exit through the air outlet. The first circuit board, which is electrically connected to and controls the operation of the ultrasonic module, is used to enclose the cavity. This flowing air also dissipates heat from the first circuit board, improving heat dissipation efficiency and ensuring the proper functioning of the first circuit board.

[0018] In some exemplary embodiments, a third air guide plate is further provided in the main body shell, one end of the third air guide plate is connected to the other end of the first air guide plate, and the other end of the third air guide plate extends to the side away from the first partition plate, and an air outlet cavity connected to the air outlet is formed between the third partition plate, the third air guide plate and the second side wall, and a second circuit board is provided in the air outlet cavity, and the second circuit board is electrically connected to the steam generator; the air duct includes the air outlet cavity, and the air outlet cavity is connected to the air guide channel.

[0019] An air outlet cavity is formed between the third partition, the third air guide plate, and the second sidewall, connecting the air guide channel and the air outlet. This allows airflow entering the air inlet and flowing through the air inlet cavity into the air guide channel to flow through the air outlet cavity and be discharged from the air outlet. A second circuit board, electrically connected to and controlling the steam generator, is positioned within the air outlet cavity. This allows airflow to dissipate heat from the second circuit board during its flow, thereby improving heat dissipation efficiency.

[0020] In some exemplary embodiments, the main unit of the garment steamer further includes a water pump, which is electrically connected to the second circuit board. The water inlet of the water pump is configured to communicate with a water source, and the water outlet of the water pump is communicated with the water inlet of the steam generator. A second installation cavity is formed between the first air guide plate, the third air guide plate and the first side wall, and the water pump is located in the second installation cavity.

[0021] By arranging the water pump in the second installation cavity formed between the first air guide plate, the third air guide plate and the first side wall, the water pump is isolated from the first circuit board and the second circuit board in the air duct, thereby achieving water and electrical isolation, so that the first circuit board and the second circuit board can work safely and reliably. At the same time, the layout of the parts in the main body shell is made more compact and reasonable, and the appearance of the main body of the hanging steamer is more compact.

[0022] In some exemplary embodiments, the main unit of the hanging steamer also includes a water tank serving as a water source. The water tank is located outside the main unit shell. One side of the main unit shell is provided with an inner recess for accommodating the water tank. The bottom wall of the inner recess is provided with ribs, and the ribs form an installation groove. The bottom of the water tank is placed in the installation groove.

[0023] The water tank is positioned outside the main unit housing, effectively separating the water source from the aforementioned electrical components and improving overall safety. Furthermore, the water tank is embedded within a recessed portion of the main unit housing, making it easy to remove and place the water tank, and thus, to refill it. The bottom wall of the recessed portion is provided with ribs that form a mounting groove, into which the bottom of the water tank is placed. The groove collects any leaking water from the tank, preventing it from dispersing. It also acts as a position limiter for the water tank, enhancing its ease of installation.

[0024] In some exemplary embodiments, the main unit of the garment steamer further includes a waste water tank, which is installed in the second installation cavity. The waste water tank is connected to the drain outlet of the steam generator through a water pipe, and a drain valve is provided on the water pipe.

[0025] The wastewater tank allows wastewater from the steam generator to be recycled, facilitating internal cleaning. Placing the wastewater tank and water pump within the second installation chamber facilitates water and electricity isolation, optimizes the structural layout of the partitioned arrangement, and improves safety.

[0026] In some exemplary embodiments, the main body of the garment steamer further includes a control panel and a control circuit board, wherein the control panel is electrically connected to the control circuit board, and the control panel and the control circuit board are located on a side of the steam generator away from the ultrasonic module.

[0027] By setting up a control panel and a control circuit board, the control panel receives user control commands, and the control circuit board controls the control panel to display the working status of the garment steamer. By setting up a control panel and a control circuit board, human-computer interaction can be achieved, and the convenience of operation is improved.

[0028] In some exemplary embodiments, the host housing is provided with heat dissipation holes.

[0029] The heat dissipation holes can be used to dissipate heat from the entire steamer body, such as the steam generator. Excessive steam generator temperatures can affect operational safety, so heat dissipation holes are provided on the body housing to dissipate heat from the steam generator. Using heat dissipation holes to dissipate heat from the steam generator is preferable to using fan-generated airflow to dissipate heat from the steam generator. This prevents the fan-generated airflow from dissipating excessive heat from the steam generator, potentially affecting the steam generator's ability to heat and produce steam.

[0030] A garment steamer comprises a steaming head assembly, a steam guide assembly and a main unit of any of the above-mentioned garment steamers, wherein the steaming head assembly is connected to the steam outlet of the steam generating device of the main unit through the steam guide assembly.

[0031] Other features and advantages of the present application will be set forth in the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0048] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the direction of the movement in a specific posture (such as the attached Figure 1 The relative position relationship and movement conditions of the components below are shown. If the specific posture changes, the directional indication will also change accordingly.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0050] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0051] like Figure 1-Figure 2 As shown, an embodiment of the present invention provides a garment steamer. The garment steamer comprises a main unit 100, an ironing head assembly 200, and a steam guide assembly 300. The ironing head assembly 200 is connected to a steam outlet 211 provided on the steam generator 2 of the main unit 100. The steam guide assembly 300 directs steam generated by the steam generator 2 to the ironing head assembly 200, thereby enabling further utilization of the steam, for example, for ironing clothes.

[0052] like Figure 2-Figure 6As shown, an embodiment of the present invention provides a main unit 100 of a garment steamer. The main unit 100 of the garment steamer is configured to include a steam generating device 2 and a main unit housing 1. The steam generating device 2 is configured to be installed inside the main unit housing 1. The steam generating device 2 is configured to include an ultrasonic module 22 and a steam generator 21. The ultrasonic module 22 is configured to be installed on the outside of the steam generator 21, that is, the ultrasonic module 22 is fixed to the steam generator 21 and is located on the outside of the steam generator 21. The ultrasonic module 22 can be installed on the lower side of the steam generator 21, or on the left side, right side, front side, rear side, etc.

[0053] The main unit 100 of the garment steamer of this embodiment is internally provided with an ultrasonic module 22, which is positioned outside the steam generator 21. This allows the main unit 100 to self-clean the steam generator 21 installed therein. Specifically, to remove scale accumulated within the steam generator 21, after the steam generator 21 is filled with water, the high-frequency vibrations generated by the ultrasonic module 22 drive the steam generator 21 to vibrate, effectively removing scale accumulated within the steam generator 21 and cleaning the steam generator 21, thus providing the main unit 100 with a self-cleaning function.

[0054] In addition, during the process of the steam generator 21 heating to generate steam, the high-frequency vibration generated by the ultrasonic module 22 can be used to atomize the water in the steam generator 21 into small droplets. The small droplets are more easily heated and vaporized into steam by the steam generator 21, thereby also achieving the effect of increasing the amount and speed of steam generation.

[0055] In some exemplary embodiments, Figure 3 As shown, the steam generator 21 is provided with a steam outlet 211, wherein the steam outlet 211 can be provided at the upper portion of the steam generator 21. The ultrasonic module 22 is mounted on the steam generator 21 and is located on a side away from the steam outlet 211. For example, the ultrasonic module 22 is disposed on the lower side of the steam generator 21, i.e., on a side close to the base 114 at the bottom of the main body housing 1.

[0056] The above arrangement ensures that the ultrasonic module 22 performs a comprehensive cleaning and descaling operation on the steam generator 21, while facilitating the ultrasonic module 22 located at the lower side to fully atomize the water at the bottom of the steam generator 21, thereby ensuring the speed of steam generation.

[0057] In some exemplary embodiments, Figure 7As shown, the steam generator 21 is configured to include a steam generator housing 212 and a heating assembly 213. A steam generating chamber 214 is formed in the steam generator housing 212, and the heating assembly 213 is disposed in the steam generating chamber 214. When the heating assembly 213 is in operation, water injected into the steam generating chamber 214 can be heated to steam.

[0058] The ultrasonic module 22 is configured to be fixed to the outside of the steam generator housing 212 .

[0059] Due to the high heating temperature of the steam generator 21, the heating surface of the heating component 213 is very prone to scale. Moreover, the steam generator 21 is a closed structure. The cleaning methods of open hot pots (such as using citric acid) are not suitable for the closed steam generator 21, making manual operation inconvenient. Moreover, the thermal conductive microstructure of the heating surface will be permanently damaged, thereby reducing the heat exchange efficiency. The ultrasonic module 22 is installed on the outside of the steam generator housing 212. The ultrasonic high-frequency vibration generated by the ultrasonic module 22 during operation will drive the entire steam generator 21 to vibrate. Therefore, when descaling the steam generator 21, the steam generating chamber 214 can be filled with water, and then the ultrasonic module 22 can be activated to effectively remove the scale generated inside the steam generator 21. In addition, during the process of the steam generator 21 heating to generate steam, the ultrasonic module 22 can be started. The high-frequency vibration generated by the ultrasonic module 22 can be used to heat the heating component 213 once, and the remaining water is atomized into small droplets. The small droplets are heated a second time after contacting the heating component 213. Since the boiling point of the small droplets is lower, they are easier to evaporate into water vapor and will quickly vaporize into steam, thereby also achieving the effect of increasing the amount and speed of steam generation.

[0060] In addition, the ultrasonic module 22 is located outside the steam generator housing 212 , thereby preventing the high temperature in the steam generating chamber 214 from affecting the normal operation of the ultrasonic module 22 .

[0061] Compared to solutions that place the ultrasonic generator inside the water tank, making it impossible to descale the steam generator, the ultrasonic module 22 of the present application can descale the steam generator 21, thereby improving the heating efficiency of the heating component 213 of the steam generator 21. Compared to solutions that place the ultrasonic assembly inside the steam generating chamber of the steam generator, the ultrasonic module 22 of the present application is located outside the steam generator housing 212, preventing the high temperature inside the steam generating chamber 214 from affecting the normal operation of the ultrasonic module 22, thereby improving the operating safety and reliability of the ultrasonic module 22.

[0062] In some exemplary embodiments, Figure 7As shown, the steam generator housing 212 includes a housing cover 215 disposed on the top and a housing base 216 disposed on the bottom, and the heating assembly 213 can be fixed to the housing cover 215, such as by screws. The lower portion of the heating assembly 213 can extend into the steam generating chamber 214.

[0063] The outer wall surface of the shell base 216 of the steam generator shell 212 is provided with an ultrasonic module mounting groove 217 for mounting the ultrasonic module 22. The ultrasonic module 22 can be installed in the above-mentioned ultrasonic module mounting groove 217 in an embedded manner, and the lower end of the ultrasonic module 22 can protrude from the ultrasonic module mounting groove 217.

[0064] The shell seat 216 can be formed into an ultrasonic module mounting groove 217 by stamping, so that the ultrasonic module mounting groove 217 protrudes into the steam generating chamber 214 (i.e., protrudes upward). On the one hand, it can prevent water accumulation in the steam generating chamber 214, which is beneficial for completely draining the water in the steam generating chamber 214 after descaling or when the steam generating device is not working; on the other hand, it can enhance the structural strength of the shell seat 216, which is beneficial for ensuring the fixing effect of the ultrasonic module 22.

[0065] In some exemplary embodiments, the ultrasonic module 22 is configured to be fixed to the steam generator housing 212 by gluing, such as being fixed to the outer wall of the housing base 216. Of course, the ultrasonic module 22 is not limited to being fixed by gluing, and can also be fixed by other means, such as snaps, rivets, screws, etc.

[0066] By attaching the ultrasonic module 22 to the steam generator housing 212 through bonding, snapping, screwing, or riveting, the complexity of assembling the ultrasonic module 22 can be effectively simplified, reducing the weight increase of the entire device due to assembly, and making the product design more lightweight. In addition, the ultrasonic module 22 can be removable through mounting methods such as snaps and screws, facilitating maintenance and replacement of the ultrasonic module 22. The specific mounting method can be selected based on the actual application and matching the corresponding requirements.

[0067] In some exemplary embodiments, Figure 7 As shown, the ultrasonic module 22 is configured to include an ultrasonic vibrator 221 and a heat insulating member 222. The heat insulating member 222 may be a heat insulating sheet, which may be disposed between the ultrasonic vibrator 221 and the steam generator housing 212. The heat insulating member 222 may isolate the steam generator housing 212 of the steam generator 21 from the ultrasonic vibrator 221, thereby reducing the heat generated by the steam generator 21 from being transferred to the ultrasonic vibrator 221, thereby preventing the high temperature generated by the steam generator 21 from causing thermal damage to the ultrasonic vibrator 221 and affecting the operation of the ultrasonic vibrator 221.

[0068] In some exemplary embodiments, the ultrasonic vibrator 221 is configured to include an ultrasonic oscillating plate. The ultrasonic oscillating plate is a key component that converts electrical energy into mechanical vibrations, and then into ultrasonic waves. Furthermore, the ultrasonic oscillating plate is lightweight and compact. Using an ultrasonic oscillating plate simplifies the structure of the ultrasonic module 22, reducing its overall size and mass.

[0069] In some exemplary embodiments, the thermal insulation member 222 may be configured as a rigid thermal insulation pad, for example, the thermal insulation member 222 may be configured as a ceramic plate or the like.

[0070] In some exemplary embodiments, the ultrasonic oscillator and the rigid thermal insulation pad can be fixed by gluing, and then the assembly of the ultrasonic oscillator and the rigid thermal insulation pad can be glued into the ultrasonic module mounting groove 217. The glue used in the above-mentioned gluing operation can be AB glue (such as industrial repair agent), etc. The selected glue should be heat-resistant and rigid after curing.

[0071] The use of a rigid thermal insulation pad, on the one hand, realizes a rigid connection between the ultrasonic oscillator and the shell 1, which can reduce the loss of ultrasonic waves caused by the provision of the thermal insulation member 222 when the ultrasonic module 22 is working, thereby improving the energy utilization effect; on the other hand, it can reduce the heat generated by the steam generator 21 from being transferred to the ultrasonic oscillator, and thus the high temperature can affect the operation of the ultrasonic oscillator.

[0072] A rigid thermal insulation pad is used, and a colloid that becomes rigid after curing is used to bond the thermal insulation pad to the ultrasonic oscillation plate, and the thermal insulation pad is bonded to the shell seat 216 of the steam generator shell 212, thereby achieving a rigid connection between the ultrasonic oscillation plate and the steam generator shell 212. This can reduce the loss of ultrasonic waves caused by the addition of the thermal insulation component 222 when the ultrasonic module 22 is working, improve energy utilization, and optimize the overall design of the product.

[0073] In some exemplary embodiments, Figure 3-Figure 5 As shown, the main body 100 of the garment steamer is configured to further include a fan 3. An air inlet 151 for air to enter and an air outlet 161 for air to flow out are provided on the main body housing 1, wherein the main body housing 1 is configured to include a first side wall 15 and a second side wall 16, which are arranged opposite to each other. The air inlet 151 can be arranged on the first side wall 15 of the main body housing 1, and the air outlet 161 can be arranged on the second side wall 16. Figure 2-Figure 6 As shown, the first side wall can be the left side wall of the host housing 1, and the second side wall 16 can be the right side wall of the host housing 1, that is, the air inlet 151 can be set on the left side wall of the host housing 1 and close to the upper part, and the air outlet 161 can be set on the right side wall of the host housing 1 and close to the lower part.

[0074] The main body housing 1 is also provided with an air duct, which connects the air inlet 151 and the air outlet 161 to form a gas flow path. The fan 3 is set in the above-mentioned air duct and can be fixed by screws. When the fan 3 is working, it can generate airflow, so that the outside air can enter from the air inlet 151, flow through the air duct, and finally be discharged from the air outlet 161 ( Figure 3 The arrows in the middle indicate the direction of gas flow).

[0075] The side of the steam generating device 2 where the ultrasonic module 22 is located (i.e., the lower portion of the steam generating device 2) extends into the air duct, so that the ultrasonic module 22 is located within the air duct. However, the side of the steam generating device 2 near the steam generator 21 (i.e., the upper portion of the steam generating device 2) does not extend into the air duct, that is, at least the upper portion of the steam generator 21 is exposed outside the air duct. The lower portion of the steam generator 21 may be located within the air duct, or the lower portion of the steam generator 21 may be exposed outside the air duct, so that the entire steam generator 21 is located outside the air duct.

[0076] This arrangement facilitates cooling of the ultrasonic module 22 extending into the air duct, thereby improving the operational reliability of the ultrasonic module 22. The upper portion of the steam generator 2 is located outside the air duct to prevent airflow from cooling or lowering the temperature of the steam generator 21. This allows the steam generator 21 to maintain a relatively high temperature, facilitating its use in heating water to generate steam.

[0077] In some exemplary embodiments, Figure 3 As shown, a first air guide plate 12 and a first partition plate 11 are provided in the main housing 1, and a gap is provided between the first air guide plate 12 and the first partition plate 11 to form an air guide channel 1111. The first air guide plate 12 and the first partition plate 11 can be arranged substantially parallel to each other, and the first air guide plate 12 can be located on one side of the first partition plate 11, as shown in FIG. Figure 3 As shown, the first air guide plate 12 and the first partition plate 11 are arranged horizontally, and the first air guide plate 12 can be arranged on the lower side of the first partition plate 11, so that the first air guide plate 12 is located between the first partition plate 11 and the base 114. The air duct includes an air guide channel 1111 between the first air guide plate 12 and the first partition plate 11.

[0078] In which, the upper part of the steam generating device 2 can be located on the upper side of the first partition 11, that is, outside the air guide channel 1111, and the lower part of the steam generating device 2 can pass through the first partition 11 and extend into the air guide channel 1111 between the above-mentioned first air guide plate 12 and the first partition 11, so that the ultrasonic module 22 is placed in the air guide channel 1111, and there is a gap between the lower end of the steam generating device 2 and the first air guide plate 12 so as not to affect the air flow in the air guide channel 1111.

[0079] The above arrangement structure allows air flow to flow through the ultrasonic module 22, directly and quickly cooling the ultrasonic module 22, avoiding problems such as decreased working efficiency, poor reliability, and even worse, loss of function caused by overheating of the ultrasonic module 22, thereby improving the service life of the steam generating device 2.

[0080] In some exemplary embodiments, Figure 3 As shown, a second partition plate 13 and a third partition plate 14 are further provided in the main body housing 1. The second partition plate 13 and the third partition plate 14 are each configured so that one end thereof is connected to the first partition plate 11, and the ends of the second partition plate 13 and the third partition plate 14 not connected to the first partition plate 11 are each configured to extend away from the first air guide plate 12.

[0081] like Figure 3 As shown, the second partition 13 and the third partition 14 are parallel to each other and relatively vertically arranged. The second partition 13 is located on the left side of the third partition 14, so that the second partition 13 is arranged close to the first side wall 15, and the third partition 14 is arranged close to the second side wall 16. The second partition 13 and the third partition 14 are both located above the first partition 11, and the lower ends of the second partition 13 and the third partition 14 are both connected to the first partition 11. Among them, the third partition 14 is connected to the right end of the first partition 11, and the second partition 13 can be connected to the left end of the first partition 11 to form a U-shaped structure, or the second partition 13 can be connected to the middle part of the first partition 11 (i.e., the non-end part, not limited to the center part of the first partition 11). According to actual assembly requirements, part or all of the first partition 11, the second partition 13 and the third partition 14 can be set as an integrally formed component, or the first partition 11, the second partition 13 and the third partition 14 can be a split structure and fixed by welding or other means.

[0082] The cavity surrounded by the above-mentioned first partition 11, second partition 13 and third partition 14 can be used as the first installation cavity 118. The first installation cavity 118 is isolated from the air guide channel 1111. The upper part of the steam generating device 2 can be set in the above-mentioned first installation cavity 118 to prevent the airflow generated by the fan 3 from cooling and lowering the temperature of the steam generator 21, and at the same time, the space in the main body shell 1 can be reasonably divided and utilized.

[0083] In some exemplary embodiments, Figure 3As shown, a second air deflector 17 is further provided in the main body housing 1. The second air deflector 17 is located on the side of the first air deflector 12 away from the base 114 (i.e., on the upper side of the first air deflector 12). One end of the second air deflector 17 is configured to be connected to the first side wall 15, and the other end of the second air deflector 17 is configured to extend toward the second partition 13. The second air deflector 17 is located between the first side wall 15 on the left and the second partition 13 on the right. A first circuit board 18 is provided between the second partition 13 and the second air deflector 17. The first circuit board 18 is configured to be electrically connected to the ultrasonic module 22 so as to control the operation of the ultrasonic module 22. The position of the second air deflector 17 can be set to be higher than the first circuit board 18, or lower than the first circuit board 18. In this case, the electronic components on the first circuit board 18 that need to dissipate heat can be set at the lower part of the first circuit board 18 so that the airflow dissipates heat for the electronic components on the first circuit board 18.

[0084] One end of the first air guide plate 12 extends to the first side wall 15, forming an air inlet cavity 1110 between the first side wall 15, the first circuit board 18, the first air guide plate 12, and the second air guide plate 17. This air inlet cavity 1110 is connected to an air inlet 151 on the first side wall 15. Specifically, the air inlet 151 is located on the portion of the first side wall 15 between the first air guide plate 12 and the second air guide plate 17. The air inlet cavity 1110 is located on a side of the air guide passage 1111 near the first side wall 15 and communicates with the air guide passage 1111, thereby connecting the air inlet cavity 1110 with the air guide passage 1111. Positioning the fan 3 within the air inlet cavity 1110, i.e., positioning the fan 3 within the entire air duct closer to the air inlet 151, fully utilizes the air entering the air duct, allowing the air to dissipate heat for a greater number of components as it flows through the air duct, including the first circuit board 18 and the ultrasonic module 22, thereby improving heat dissipation efficiency.

[0085] In some exemplary embodiments, Figure 3 As shown, a third air guide plate 19 is further provided in the main body housing 1. One end of the third air guide plate 19 is connected to the end of the first air guide plate 12 close to the second side wall 16, and the end of the third air guide plate 19 not connected to the first air guide plate 12 extends to the side away from the first partition 11. Figure 3 As shown, third partition plate 19 is vertically disposed, with its upper end connected to the right end of first air guide plate 12 and its lower end extending toward base 114. The cavity formed between second sidewall 16, third partition plate 14, and third air guide plate 19 can serve as an outlet cavity 1112. This outlet cavity 1112 is connected to air outlet 161 and to air guide channel 1111. That is, outlet cavity 1112 connects air guide channel 1111 with air outlet 161. Of course, the air duct also includes outlet cavity 1112, that is, air inlet cavity 1110, air guide channel 1111, and air outlet cavity 1112 are sequentially connected to form the air duct.

[0086] A second circuit board 110 is disposed within the air outlet cavity 1112. The second circuit board 110 is electrically connected to the steam generator 21 to control the operation of the steam generator 21. The second circuit board 110 is disposed within the air outlet cavity 1112 so that the air flowing therethrough dissipates heat from the second circuit board 110, thereby improving heat dissipation efficiency.

[0087] In some exemplary embodiments, Figure 3 As shown, the main unit 100 of the garment steamer is configured to further include a water pump 4, wherein the water pump 4 is configured to be fixed to the base 114 (for example, by a clamping structure or screws). The water pump 4 is also configured to be electrically connected to the second circuit board 110, so that the water pump 4 and the steam generator 21 are controlled by the second circuit board 110 together, simplifying the complexity of the component layout and improving the sensitivity of the control and real-time adjustment of the steam generation amount.

[0088] The water inlet of the water pump 4 is arranged to be connected to the water source, and the water outlet of the water pump 4 is arranged to be connected to the water inlet of the steam generator 21. A control valve can be set on the water injection pipeline between the water source and the water inlet of the steam generator 21. The control valve can be used to control the opening or closing of the water injection pipeline or the water flow rate to improve the accuracy and safety of water supply.

[0089] A second installation cavity 119 is formed between the first side wall 15 , the first air guide plate 12 , the third air guide plate 19 and the base 114 , and the water pump 4 is disposed in the second installation cavity 119 .

[0090] In some exemplary embodiments, Figure 2-Figure 6 As shown, the main unit 100 of the garment steamer is configured to also include a wastewater tank 6, which can be used to store wastewater after descaling the steam generator 21. The wastewater tank 6 is similarly mounted within the aforementioned second mounting cavity 119, and the water pump 4 is positioned to the right of the wastewater tank 6. The wastewater tank 6 is connected to the drain outlet of the steam generator 21 via a flexible water pipe. In addition, to control wastewater discharge, a drain valve (such as a flow control valve) can be installed on the water pipe, and this drain valve can be a solenoid valve for automatic control.

[0091] As can be seen, an air duct is provided between the first mounting cavity 118 and the second mounting cavity 119, so that the main electrical components (first circuit board 18, second circuit board 110, steam generator 2, etc.) are located on one side of the air duct, and the main waterway components (such as water pump 4, wastewater tank 6, etc.) are located on the other side of the air duct. The relative arrangement of the electrical components and the waterway components can improve the reliability of the entire garment steamer main unit 100 and prevent electrical component short circuits and other faults. In addition, this structural arrangement makes the layout of the components within the main unit housing 1 more compact and reasonable, and the overall appearance of the garment steamer main unit 100 is more compact.

[0092] In some exemplary embodiments, Figure 2 、 Figure 4-Figure 6 As shown, the water tank 5 can be used as a water source. The main unit 100 of the garment steamer is configured to also include the water tank 5, and the water tank 5 is arranged outside the main unit shell 1, which is convenient for observing the water storage amount in the water tank 5, and also convenient for filling water into the water tank 5, and also convenient for cleaning the water tank 5 separately.

[0093] A recessed portion 115 for accommodating the water tank 5 is provided on a side wall of the main housing 1. A rib 116 is provided on the bottom wall of recessed portion 115. Ribs 116 can be annular, forming a mounting groove 117 for accommodating the water tank 5. Alternatively, ribs 116 can cooperate with the rear sidewall of the main housing 1 to form mounting groove 117. The bottom of the water tank 5 can be mounted within mounting groove 117, which collects any leaking water from the water tank 5 to prevent it from dispersing. Furthermore, mounting groove 117 serves to limit the position of the water tank 5, making it easier to install.

[0094] The water tank 5 can be fixed to the rear side wall of the main body shell 1 by snapping or the like, which facilitates the placement and removal of the water tank 5 and further facilitates the addition of water to the water tank 5 .

[0095] In some exemplary embodiments, Figure 2 As shown, the main unit 100 of the garment steamer is configured to also include a control circuit board 112 and a control panel 111. The control panel 111 is electrically connected to the control circuit board 112. The control panel 111 has a display function and operation buttons for selecting and displaying the functions of the entire machine. The control panel 111 receives user control commands, and the control circuit board 112 controls the control panel 111 to display the operating status of the garment steamer. The configuration of the control panel and control circuit board enables human-computer interaction and improves operational convenience.

[0096] In some exemplary embodiments, Figure 2 and Figure 3As shown, the control panel 111 and the control circuit board 112 are both located on the side of the steam generator 21 away from the ultrasonic module 22, that is, the control panel 111 and the control circuit board 112 are arranged on the upper side of the main body housing 1, which is convenient for the user to identify and touch the control panel 111 and the control circuit board 112. The control panel 111 and the control circuit board 112 can be fixed by screws or other means.

[0097] One of the control circuit board 112, the first circuit board 18 and the second circuit board 110 can serve as a main control board, and the other two are electrically connected to the main control board to uniformly and centrally control the overall operation of the main body 100 of the garment steamer.

[0098] In some exemplary embodiments, Figure 2 、 Figure 4 As shown, the main body housing 1 is also provided with a plurality of heat dissipation holes 113 dispersedly disposed therein for dissipating heat from the entire main body 100 of the garment steamer, such as dissipating heat from the steam generator 21 to avoid safety issues caused by excessive temperatures of the steam generator 21. The heat dissipation holes 113 may be disposed on the first side wall 15 of the main body housing 1 and located above the air inlet 151.

[0099] The main unit 100 of the garment steamer of an embodiment of the present invention includes all functional components for steam generation and cleaning. The steam generated by the steam generating device 2 is transmitted to the ironing head component 200 through the steam guide component 300. The ironing head component 200 directly acts on the clothes or fabrics to be ironed to realize functions such as ironing and deodorization.

[0100] To summarize, the embodiment of the present application provides a main unit of a hanging steamer, in which an ultrasonic module is installed at the bottom of the steam generator. When descaling the steam generator, after the steam generator is filled with water, the ultrasonic vibration energy generated by the ultrasonic module produces a cavitation effect, which can completely crush the flaky dirt generated on the heating surface inside the steam generator; during the operation of the steam generator, a small amount of water can be injected into the bottom of the steam generator, and the ultrasonic high-frequency vibration energy generated by the ultrasonic module will shatter the water into atomized small droplets. The boiling point of the small droplets is lower than that of water, and they are easier to be heated to produce steam. At the same time, after the water is atomized, it is easier to contact the heating surface, thereby improving the heating efficiency, thereby increasing the amount of steam generated by the entire machine and the speed of steam generation.

[0101] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
