[0005] The second aspect of the present invention further provides a household appliance.

[0006] In view of this, the first aspect of the present invention proposes a steam generating device for household appliances, the steam generating device comprising: a pot body, the bottom wall of the pot body being provided with a through hole, and the pot body being capable of generating steam; an isolating member comprising a bracket and a sealing portion, the bracket being arranged at the through hole, the bracket comprising a water inlet channel, the water inlet channel comprising a water inlet and a water outlet, the water outlet being connected to the pot body, the sealing portion being arranged in the water inlet channel and being capable of moving in the water inlet channel to connect or disconnect the water inlet and the water outlet.

[0007] The steam generating device provided by the present invention includes a pot body and an isolating member, wherein the bottom wall of the pot body is provided with a through hole, the isolating member includes a bracket and a sealing member, the bracket is arranged at the through hole, wherein the bracket includes a water inlet channel, the water inlet channel includes a water inlet and a water outlet, the sealing member is arranged in the water inlet channel and is movable in the channel, thereby enabling the water inlet and the water outlet to be connected or disconnected. When the water inlet and the water outlet are connected, liquid can be transported into the pot body through the water inlet channel; when the water inlet and the water outlet are disconnected, under the action of the gravity of the liquid, steam and the sealing member in the pot body, the sealing member is tightly pressed in the water inlet channel to seal the water inlet channel, thereby preventing the steam and high-temperature and high-pressure liquid in the pot body from flowing from the water inlet channel to the water inlet, thereby ensuring the steam pressure in the pot body, reducing steam overflow, and preventing the high-temperature and high-pressure liquid and steam in the pot body from flowing to the water supply part and causing damage to the water supply part.

[0008] The steam generating device provided by the present invention may also have the following additional technical features:

[0009] In some embodiments, optionally, the household appliance includes a water supply part, and the water inlet is connected to the water supply part, wherein when the water supply part transports liquid to the water inlet, the sealing part can be lifted up by the liquid, and when the water supply part is closed, the sealing part can fall back and seal the water inlet channel to disconnect the water inlet and the water outlet.

[0010] In this embodiment, the household appliance includes a water supply unit that is connected to a water inlet and is configured to transport liquid into the pot through the water inlet. When the water supply unit is open, the water supply unit transports liquid to the water inlet, gradually increasing the water inlet pressure. When the water inlet pressure exceeds the sum of the weight of the sealing unit, the pressure of the liquid in the pot acting on the sealing unit, and the pressure of the steam, the sealing unit is lifted, connecting the water inlet and the water outlet, thereby enabling liquid transport. When the water supply unit is closed, the water supply unit no longer transports liquid to the water inlet, and the water inlet pressure disappears, causing the sealing unit to fall back under the action of its own weight, the pressure of the liquid in the pot, and the pressure of the steam, thereby resealing the water inlet channel and disconnecting the water inlet and the water outlet. This prevents both liquid leakage and steam in the pot from flowing from the water inlet to the water supply unit, thereby preventing damage to the water supply unit.

[0011] In some embodiments, optionally, the water inlet channel is arranged in a vertical direction, and the sealing portion can move in the vertical direction within the water inlet channel.

[0012] In this embodiment, the water inlet channel is arranged in the vertical direction, so that the sealing part can move in the water inlet channel under the liquid pressure of the water supply part and its own weight, ensuring the reliability of the sealing part when it falls back.

[0014] In this embodiment, the isolation member also includes a reset part, which connects the sealing part and the bracket. When the water supply part is closed, the reset part can drive the sealing part to fall back, so that the sealing part seals the water inlet channel and the water inlet and the water outlet are disconnected.

[0015] In some embodiments, optionally, the water inlet channel further includes a sealing fitting area, which is located between the water inlet and the water outlet, wherein the cross-sectional area of ​​the sealing fitting area gradually decreases from the end close to the water outlet to the end far from the water outlet, and the sealing part seals the water inlet channel when the sealing part contacts the inner wall surface of the sealing fitting area along the circumference.

[0016] In this embodiment, the water inlet channel also includes a sealing fitting area, which is located between the water inlet and the water outlet. When the sealing portion is located in the sealing fitting area, the sealing portion contacts the inner wall surface of the sealing fitting area along the circumference, so that the sealing fitting area is sealed, thereby disconnecting the water inlet and the water outlet. The cross-sectional area of ​​the sealing fitting area gradually decreases from the end close to the water outlet to the end away from the water outlet, so that the sealing portion can form a seal with the inner wall surface of the sealing fitting area during the falling process.

[0017] In some embodiments, optionally, there are multiple water outlets, and the multiple water outlets are arranged on the side wall of the water inlet channel and are arranged at intervals along the circumference of the water inlet channel; and / or the bracket is passed through the through hole, and one end of the water inlet channel with the water inlet is located on the outside of the pot body; and / or the sealing part includes a sealing ball.

[0018] In this embodiment, multiple water outlets are spaced circumferentially around the water inlet channel, increasing water inlet efficiency. A bracket is inserted through the through-hole, positioning the water inlet outside the pot body for easy communication with the water supply. The sealing element includes a sealing ball, ensuring a secure seal.

[0019] In some embodiments, optionally, the isolating member further includes: a cover body, which is provided at an end of the water inlet channel away from the water inlet.

[0020] In this embodiment, a cover is provided at the end of the water inlet channel away from the water inlet, and the sealing part can be installed in the water inlet channel from the end of the water inlet channel away from the water inlet, and then the cover is covered to prevent the sealing part from detaching from the water inlet channel.

[0021] In some embodiments, optionally, the cover is threadedly or adhesively connected to the bracket.

[0022] In this embodiment, the cover body is connected to the bracket by threads or adhesives, thereby limiting the position of the sealing portion. At the same time, when the sealing portion is damaged, the cover body can be removed and the sealing portion can be replaced.

[0023] In some embodiments, optionally, the bracket is connected to the pot body by welding or bonding.

[0024] In this embodiment, the bracket is connected to the pot body by welding or bonding. The welding connection improves the connection strength between the bracket and the pot body, and the bonding connection reduces damage to the pot body.

[0025] According to a second aspect of the present invention, a household appliance is further provided, comprising: a steam generating device as provided in any one of the above embodiments.

[0026] The household appliance provided in the second aspect of the present invention comprises the steam generating device proposed in any of the above technical solutions and thus has all the beneficial effects of the steam generating device.

[0027] In some embodiments, optionally, the household appliance further includes: a water supply part, which is connected to the water inlet and is used to transport liquid to the water inlet, and the sealing part can be lifted by the liquid to connect the water inlet and the water outlet.

[0028] In this embodiment, the household appliance further comprises a water supply unit, which is connected to the water inlet and is used to transport liquid into the pot through the water inlet. When the water supply unit is open, the water supply unit transports liquid to the water inlet, causing the water inlet pressure to gradually increase. When the water inlet pressure is greater than the sum of the weight of the sealing unit, the pressure of the liquid in the pot acting on the sealing unit, and the pressure of the steam, the sealing unit is lifted up, connecting the water inlet and the water outlet, thereby achieving liquid transport. When the water supply unit is closed, the water supply unit no longer transports liquid to the water inlet, and the water inlet pressure disappears, causing the sealing unit to fall back under the action of its own weight, the pressure of the liquid in the pot, and the pressure of the steam, thereby resealing the water inlet channel and disconnecting the water inlet and the water outlet. This prevents both liquid leakage and steam in the pot from flowing from the water inlet to the water supply unit, thus preventing damage to the water supply unit.

[0029] In some embodiments, optionally, the water supply part includes a pump body and a water tank assembly, and the pump body is connected between the water tank assembly and the water inlet, and is used to pump the liquid in the water tank assembly into the pot body through the water inlet.

[0030] In this embodiment, the water supply part includes a pump body and a water tank assembly. The water tank assembly is used to contain liquid, and the pump body is used to pump the liquid in the water tank assembly to the water inlet, and then lift the sealing part and supply water into the pot body.

[0031] In some embodiments, optionally, the household appliance is any one of a garment steamer, a steamer, and a steam-bake-in-one machine.

[0032] In this embodiment, the household appliance can be any one of a hanging iron, a steamer, and a steam-bake combination machine, so as to process clothes or food by steam. During the steam treatment process, steam overflow is avoided and steam pressure is guaranteed.

[0033] In some embodiments, optionally, when the household appliance is a garment steamer, the garment steamer further includes: a main unit, in which a pot is disposed; an ironing assembly, disposed in the main unit and connected to the pot, and the pot can deliver steam to the ironing assembly.

[0034] In this embodiment, if the household appliance is a garment steamer, the garment steamer further comprises a main unit and an ironing assembly. The steamer is disposed within the main unit, and the ironing assembly is in communication with the main unit, allowing steam generated by the main unit to be transported to the ironing assembly, thereby ironing clothes. Furthermore, a water tank assembly is in communication with the main unit for transporting liquid into the ironing assembly, allowing the ironing assembly to continuously output steam. The hanging steamer proposed in the present application has a sealing part that can realize the connection and disconnection of the water inlet and the water outlet. When the water inlet and the water outlet are connected, the liquid can be transported into the pot body through the water inlet channel, so that the liquid level in the pot body is maintained within a certain range, avoiding the situation where the pot body is dry-burned or the steam amount is weakened due to the low liquid level in the pot body, thereby enabling the pot body to continuously and stably generate steam, and the steam output by the ironing component to be continuous and stable, so as to ensure the ironing effect; when the water inlet and the water outlet are disconnected, under the action of the gravity of the liquid, steam and the sealing part in the pot body, the sealing part is tightly pressed in the water inlet channel to seal the water inlet channel, so that the steam and high-temperature and high-pressure liquid in the pot body cannot flow from the water inlet channel to the water inlet. While avoiding damage to the water supply part, it can also ensure the steam pressure in the pot body, reduce steam overflow, and thereby ensure the steam pressure output by the ironing component, so that the ironing operation of the ironing component can be carried out continuously.

[0035] In some embodiments, optionally, the main unit includes: a back panel; a panel, which is arranged on one side of the back panel and encloses an installation cavity together with the back panel, the pot body is arranged in the installation cavity, and the top of the panel is recessed into the installation cavity to form a first installation groove and a second installation groove, the first installation groove and the second installation groove are arranged side by side relative to the back panel, the ironing assembly is arranged in the first installation groove, and the water tank assembly is arranged in the second installation groove.

[0036] In this embodiment, the main unit includes a back panel and an enclosure. The enclosure is arranged on one side of the back panel and encloses an installation cavity together with the back panel. The pot body is arranged in the installation cavity to protect the pot body and prevent the high temperature of the pot body from scalding the user during operation. The top of the enclosure is recessed into the installation cavity to form a first installation slot and a second installation slot. The ironing assembly is arranged in the first installation slot, and the water tank assembly is arranged in the second installation slot. On the one hand, this arrangement allows the ironing assembly and the water tank assembly to be arranged on the same side of the back panel, making the garment steamer flat as a whole, thereby facilitating the storage of the garment steamer. On the other hand, this arrangement allows the water tank assembly and the ironing assembly to be located on the top of the enclosure, thereby facilitating the removal and placement of the ironing assembly and the water tank assembly. As for the water tank assembly, it can be refilled without lifting the water tank assembly, making the garment steamer more convenient to use.

[0037] In some embodiments, optionally, the garment steamer further includes: a filter, which is disposed at the bottom of the water tank assembly and is connected between the water tank assembly and the pump body.

[0038] In this embodiment, the garment steamer also includes a filter, which is arranged at the bottom of the water tank assembly and is connected to the water tank assembly, thereby filtering the liquid transported from the water tank assembly to the pot body, improving the water quality of the liquid, and avoiding the formation of scale in the pot body.

[0039] Optionally, the garment steamer further includes a water level detection assembly, which is provided in the pot body and is used to detect the water level in the pot body. When the water level in the pot body is lower than a first water level, the control unit turns on the pump body, so that the liquid in the water tank assembly is replenished into the pot body, thereby preventing the pot body from dry burning or insufficient steam resulting in a reduction in the steam volume. When the water level in the pot body is higher than a second water level, the control unit turns off the pump body and stops supplying liquid into the pot body, thereby preventing water from spraying when the liquid level in the pot body is too high, thereby preventing the water from affecting the ironing effect. The garment steamer proposed in this application can achieve continuous output of steam from the pot body by providing a water level detection assembly.

[0040] It can be understood that the first water level is lower than the second water level.

DETAILED DESCRIPTION

[0056] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0057] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0058] Refer to the following Figures 1 to 11 The present invention describes a steam generating device and a household appliance according to some embodiments of the present invention.

[0059] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, according to one embodiment of the present invention, a steam generating device for use in a household appliance is provided. The steam generating device includes a pot body 1 and an isolating member 2. The pot body 1 has a through hole 10 formed on its bottom wall, enabling the pot body 1 to generate steam. The isolating member 2 includes a bracket 20 and a sealing member 22. The bracket 20 is positioned at the through hole 10 and includes a water inlet channel 200. The water inlet channel 200 includes a water inlet 202 and a water outlet 204, which is in communication with the pot body 1. The sealing member 22 is positioned within the water inlet channel 200 and is movable within the water inlet channel 200 to connect or disconnect the water inlet 202 and the water outlet 204.

[0060] The steam generating device provided by the present invention includes a pot body 1 and an isolating member 2. The bottom wall of the pot body 1 is provided with a through hole 10. The isolating member 2 includes a bracket 20 and a sealing portion 22. The bracket 20 is arranged at the through hole 10, wherein the bracket 20 includes a water inlet channel 200, and the water inlet channel 200 includes a water inlet 202 and a water outlet 204. The sealing portion 22 is arranged in the water inlet channel 200 and can move in the channel, thereby enabling the water inlet 202 and the water outlet 204 to be connected or disconnected. When the water inlet 202 and the water outlet 204 are connected, liquid can be transported into the pot body 1 through the water inlet channel 200; when the water inlet 202 and the water outlet 204 are disconnected, under the action of the gravity of the liquid, steam and the sealing part 22 in the pot body 1, the sealing part 22 is tightly pressed against the water inlet channel 200 to seal the water inlet channel 200, and then the steam and high-temperature and high-pressure liquid in the pot body 1 cannot flow from the water inlet channel 200 to the water inlet 202, which can ensure the steam pressure in the pot body 1, reduce steam overflow, and prevent the high-temperature and high-pressure liquid and steam in the pot body 1 from flowing to the water supply part 3 and causing damage to the water supply part 3.

[0061] It can be understood that the movement of the sealing part 22 can be achieved through electrical control or mechanical drive. For example, when liquid is transported to the water inlet 202, the sealing part 22 can be moved under the pressure of the liquid, thereby causing the sealing part 22 to open the connecting channel between the water inlet 202 and the water outlet 204, so that the liquid can be transported into the pot body 1; when the water supply is stopped, the sealing part 22 can also re-seal the connecting channel between the water inlet 202 and the water outlet 204 under the action of gravity or the action of the reset part 24, thereby preventing steam or high-temperature and high-pressure liquid from flowing from the water inlet channel 200 to the water supply part 3.

[0062] It should be noted that the isolation member 2 proposed in this application is arranged at the through hole 10 of the pot body 1, so that the isolation member 2 is integrated with the pot body 1. There is no need to improve the water supply part 3, nor is there a need to set a one-way valve on the pipeline between the water supply part 3 and the water inlet 202, so that the steam generating device proposed in this application has a simple and reliable structure.

[0063] Optionally, the bracket 20 is a separate structure, or the bracket 20 and the bottom wall of the pot body 1 are an integrated structure.

[0064] Optionally, the steam generating device further comprises a heating element, which is used to heat the pot body 1 so that the liquid in the pot body 1 generates steam.

[0065] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, in some embodiments, optionally, the household appliance includes a water supply part 3, and the water inlet 202 is connected to the water supply part 3, wherein when the water supply part 3 transports liquid to the water inlet 202, the sealing part 22 can be lifted up by the liquid, and when the water supply part 3 is closed, the sealing part 22 can fall back and seal the water inlet channel 200, so that the water inlet 202 and the water outlet 204 are disconnected.

[0066] In this embodiment, the household appliance includes a water supply unit 3, which is connected to the water inlet 202 and is used to transport liquid into the pot body 1 through the water inlet 202. Figure 4 and Figure 5 As shown, when the water supply part 3 is opened, the water supply part 3 supplies liquid to the water inlet 202, so that the water inlet pressure gradually increases. When the water inlet pressure is greater than the sum of the weight of the sealing part 22, the pressure of the liquid in the pot body 1 acting on the sealing part 22, and the pressure of the steam, the sealing part 22 is pushed up, and the water inlet 202 and the water outlet 204 are connected, thereby realizing the liquid supply to the pot body 1; Figure 2 and Figure 3 As shown, when the water supply part 3 is closed, the water supply part 3 no longer transports liquid to the water inlet 202, and the water inlet pressure disappears, causing the sealing part 22 to fall back under the action of its own gravity, the pressure of the liquid in the pot body 1 and the pressure of the steam, and then reseal the water inlet channel 200, so that the water inlet 202 and the water outlet 204 are disconnected, which can prevent liquid leakage and prevent the steam in the pot body 1 from flowing from the water inlet 202 to the water supply part 3, thereby preventing the water supply part 3 from being damaged.

[0067] It should be noted that the density of the sealing part 22 is greater than the density of the liquid, so that the sealing part 22 can sink when the pot body 1 is filled with liquid, and then the water inlet channel 200 is sealed by the weight of the sealing part 22, the pressure of the liquid and the steam above the liquid.

[0068] In some embodiments, optionally, the water inlet channel 200 is arranged along the vertical direction, and the sealing portion 22 can move along the vertical direction within the water inlet channel 200 .

[0069] In this embodiment, the water inlet channel 200 is arranged in the vertical direction, so that the sealing part 22 can move in the water inlet channel 200 under the liquid pressure of the water supply part 3 and its own weight, ensuring the reliability of the sealing part 22 when it falls back.

[0070] like Figure 6 As shown, in some embodiments, optionally, the isolating member 2 further includes: a reset portion 24 , the reset portion 24 connecting the sealing portion 22 and the bracket 20 , and configured to drive the sealing portion 22 to reset so as to disconnect the water inlet 202 and the water outlet 204 .

[0071] In this embodiment, the isolation member 2 also includes a reset portion 24, which connects the sealing portion 22 and the bracket 20. The reset portion 24 can drive the sealing portion 22 to fall back when the water supply portion 3 is closed, so that the sealing portion 22 seals the water inlet channel 200, and the water inlet 202 and the water outlet 204 are disconnected.

[0072] Optionally, the reset portion 24 includes a spring, elastic rubber, or elastic silicone.

[0073] Optionally, the reset portion 24 is connected to the bottom of the sealing portion 22, and when the sealing portion 22 seals the water inlet channel 200 to disconnect the water inlet 202 and the water outlet 204, the reset portion 24 is in a stretched state to pull the sealing portion 22 downward, thereby ensuring the reliability of the seal of the water inlet channel 200. Alternatively, the reset portion 24 is located at the top of the sealing portion 22, and when the sealing portion 22 seals the water inlet channel 200 to disconnect the water inlet 202 and the water outlet 204, the reset portion 24 is in a compressed state to press the sealing portion 22 downward, thereby ensuring the reliability of the seal of the water inlet channel 200.

[0074] like Figure 3 and Figure 5 As shown, in some embodiments, optionally, the water inlet channel 200 further includes a sealing fitting area 206, which is located between the water inlet 202 and the water outlet 204, wherein the cross-sectional area of ​​the sealing fitting area 206 gradually decreases from one end close to the water outlet 204 to the end away from the water outlet 204, and when the sealing portion 22 contacts the inner wall surface of the sealing fitting area 206 along the circumference, the sealing portion 22 seals the water inlet channel 200.

[0075] In this embodiment, the water inlet channel 200 also includes a sealing fitting area 206, which is located between the water inlet 202 and the water outlet 204. When the sealing portion 22 is located in the sealing fitting area 206, the sealing portion 22 contacts the inner wall surface of the sealing fitting area 206 along the circumference, so that the sealing fitting area 206 is sealed, thereby disconnecting the water inlet 202 and the water outlet 204. The cross-sectional area of ​​the sealing fitting area 206 gradually decreases from the end close to the water outlet 204 to the end away from the water outlet 204, so that the sealing portion 22 can form a seal with the inner wall surface of the sealing fitting area 206 during the falling process.

[0076] Optionally, the distance in the vertical direction between the portion of the sealing portion 22 that contacts the sealing matching area 206 and the inner bottom wall of the pot body 1 is greater than or equal to 0 mm and less than or equal to 50 mm.

[0077] In some embodiments, optionally, there are multiple water outlets 204, and the multiple water outlets 204 are arranged on the side wall of the water inlet channel 200 and are arranged at intervals along the circumference of the water inlet channel 200; and / or the bracket 20 is passed through the through hole 10, and the water inlet channel 200 is provided with an end of the water inlet 202 located on the outside of the pot body 1; and / or the sealing part 22 includes a sealing ball.

[0078] In this embodiment, multiple water outlets 204 are spaced apart circumferentially around the water inlet channel 200, increasing water inlet efficiency. Bracket 20 extends through through-hole 10, positioning water inlet 202 outside of pot body 1 and facilitating communication between water inlet 202 and water supply unit 3. Sealing element 22 includes a sealing ball, ensuring a secure seal.

[0079] Optionally, the sealing matching area 206 is in a truncated cone shape, which improves the adaptability between the sealing ball and the sealing matching area 206 and thereby improves the sealing effect.

[0080] like Figure 7 and Figure 8 As shown, in some embodiments, optionally, the isolating member 2 further includes: a cover 26 , which is provided at one end of the water inlet channel 200 away from the water inlet 202 .

[0081] In this embodiment, a cover body 26 is provided at the end of the water inlet channel 200 away from the water inlet 202, and the sealing part 22 can be installed in the water inlet channel 200 from the end of the water inlet channel 200 away from the water inlet 202, and then covered with the cover body 26 to prevent the sealing part 22 from detaching from the water inlet channel 200.

[0082] In some embodiments, the cover 26 is optionally connected to the bracket 20 by threads or adhesives.

[0083] In this embodiment, the cover 26 is threadedly or adhesively connected to the bracket 20 to limit the sealing portion 22. When the sealing portion 22 is damaged, the cover 26 can be removed and the sealing portion 22 can be replaced.

[0084] In some embodiments, optionally, the bracket 20 is connected to the pot body 1 by welding or bonding.

[0085] In this embodiment, the bracket is connected to the pot body 1 by welding or bonding. The welding connection improves the connection strength between the bracket 20 and the pot body 1, and the bonding connection reduces damage to the pot body 1.

[0086] Optionally, a sealing ring is provided between the bracket 20 and the through hole 10 to prevent liquid leakage from the connection between the bracket 20 and the through hole 10 .

[0089] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, in some embodiments, optionally, the household appliance further includes: a water supply part 3, the water supply part 3 is connected to the water inlet 202, the water supply part 3 is used to transport liquid to the water inlet 202, and the sealing part 22 can be lifted by the liquid to connect the water inlet 202 and the water outlet 204.

[0090] In this embodiment, the household appliance further includes a water supply portion 3 , which is in communication with the water inlet 202 and is used for conveying liquid into the pot body 1 through the water inlet 202 . Among them, when the water supply part 3 is opened, the water supply part 3 transports liquid to the water inlet 202, so that the water inlet pressure gradually increases. When the water inlet pressure is greater than the sum of the dead weight of the sealing part 22, the pressure of the liquid in the pot body 1 acting on the sealing part 22 and the pressure of the steam, the sealing part 22 is lifted up, and the water inlet 202 and the water outlet 204 are connected, thereby realizing the liquid transportation into the pot body 1; when the water supply part 3 is closed, the water supply part 3 no longer transports liquid to the water inlet 202, and the water inlet pressure disappears, so that the sealing part 22 falls back under the action of its own gravity, the pressure of the liquid in the pot body 1 and the pressure of the steam, and then reseals the water inlet channel 200, so that the water inlet 202 and the water outlet 204 are disconnected, which can not only prevent liquid leakage, but also prevent the steam in the pot body 1 from flowing from the water inlet 202 to the water supply part 3, thereby preventing the water supply part 3 from being damaged.

[0091] like Figure 1 and Figure 9 As shown, in some embodiments, optionally, the water supply part 3 includes a pump body 30 and a water tank assembly 32, and the pump body 30 is connected between the water tank assembly 32 and the water inlet 202, and is used to pump the liquid in the water tank assembly 32 into the pot body 1 through the water inlet 202.

[0092] In this embodiment, the water supply part 3 includes a pump body 30 and a water tank assembly 32. The water tank assembly 32 is used to hold liquid. The pump body 30 is used to pump the liquid in the water tank assembly 32 to the water inlet 202, and then lift the sealing part 22 to supply water into the pot body 1.

[0093] In some embodiments, optionally, the household appliance is any one of a garment steamer, a steamer, and a steam-bake-in-one machine.

[0094] In this embodiment, the household appliance can be any one of a hanging iron, a steamer, and a steam-bake combination machine, so as to process clothes or food by steam. During the steam treatment process, steam overflow is avoided and steam pressure is guaranteed.

[0095] like Figure 10 and Figure 11 As shown, in some embodiments, optionally, when the household appliance is a garment steamer, the garment steamer further includes: a main unit 4, in which the pot body 1 is disposed; an ironing component 5, which is disposed in the main unit 4 and is connected to the pot body 1, and the pot body 1 can deliver steam to the ironing component 5.

[0096] In this embodiment, when the household appliance is a hanging steamer, the hanging steamer further includes a main unit 4 and an ironing assembly 5. The pot body 1 is arranged in the main unit 4, and the ironing assembly 5 is connected to the pot body 1, so that the steam generated by the pot body 1 can be transported to the ironing assembly 5, and then the clothes are ironed by the ironing assembly 5. At the same time, the water tank assembly 32 is connected to the pot body 1, and is used to transport liquid into the pot body 1, so that the pot body 1 can continuously output steam. The hanging steamer proposed in this application, the sealing part 22 can realize the connection and disconnection of the water inlet 202 and the water outlet 204. When the water inlet 202 and the water outlet 204 are connected, the liquid can be transported into the pot body 1 through the water inlet channel 200, so that the liquid level in the pot body 1 is maintained within a certain range, avoiding the situation where the pot body 1 is dry-burned or the steam amount is reduced due to the low liquid level in the pot body 1, so that the pot body 1 can continuously and stably generate steam, so that the steam output by the ironing assembly 5 can be continuous and stable to ensure the ironing effect; at the water inlet 2 02 and the water outlet 204 are disconnected, under the action of the liquid, steam and gravity of the sealing part 22 in the pot body 1, the sealing part 22 is tightly pressed against the water inlet channel 200 to seal the water inlet channel 200, so that the steam and high-temperature and high-pressure liquid in the pot body 1 cannot flow from the water inlet channel 200 to the water inlet 202, while avoiding damage to the water supply part 3, it can also ensure the steam pressure in the pot body 1, reduce steam overflow, and thus ensure the steam pressure output by the ironing component 5, so that the ironing operation of the ironing component 5 can continue.

[0097] In some embodiments, optionally, the main unit 4 includes: a back panel 40; a surrounding panel 42, which is arranged on one side of the back panel 40 and together with the back panel 40 to form an installation cavity 44, the pot body 1 is arranged in the installation cavity 44, and the top of the surrounding panel 42 is recessed into the installation cavity 44 to form a first installation groove 420 and a second installation groove 422, the first installation groove 420 and the second installation groove 422 are arranged side by side relative to the back panel 40, the ironing component 5 is arranged in the first installation groove 420, and the water tank component 32 is arranged in the second installation groove 422.

[0098] In this embodiment, the main unit 4 includes a back panel 40 and a surrounding panel 42. The surrounding panel 42 is arranged on one side of the back panel 40 and together with the back panel 40, forms an installation cavity 44. The pot body 1 is arranged in the installation cavity 44, thereby protecting the pot body 1 and preventing the high temperature of the pot body 1 from scalding the user when the pot body 1 is working. The top of the enclosure 42 is recessed into the mounting cavity 44 to form a first mounting groove 420 and a second mounting groove 422. The ironing assembly 5 is arranged in the first mounting groove 420, and the water tank assembly 32 is arranged in the second mounting groove 422. On the one hand, this arrangement enables the ironing assembly 5 and the water tank assembly 32 to be arranged on the same side of the back panel 40, so that the garment steamer is flat as a whole, which is convenient for the storage of the garment steamer. On the other hand, this arrangement enables the water tank assembly 32 and the ironing assembly 5 to be located at the top of the enclosure 42, which is convenient for taking and placing the ironing assembly 5 and the water tank assembly 32. For the water tank assembly 32, the water tank assembly 32 can be replenished without lifting the water tank assembly 32, making the use of the garment steamer more convenient.

[0099] In some embodiments, optionally, the garment steamer further includes: a filter 6 , which is disposed at the bottom of the water tank assembly 32 and is connected between the water tank assembly 32 and the pump body 30 .

[0100] In this embodiment, the garment steamer also includes a filter 6, which is arranged at the bottom of the water tank assembly 32 and is connected to the water tank assembly 32, thereby filtering the liquid transported from the water tank assembly 32 to the pot body 1, thereby improving the water quality of the liquid and preventing scale from forming in the pot body 1.

[0101] Optionally, the garment steamer further includes a water level detection component, which is provided in the pot body 1 and is used to detect the water level in the pot body 1. When the water level in the pot body 1 is lower than a first water level, the control unit turns on the pump body 30, so that the liquid in the water tank assembly 32 is replenished into the pot body 1, thereby preventing the pot body 1 from drying out or reducing the steam volume due to insufficient steam. When the water level in the pot body 1 is higher than a second water level, the control unit turns off the pump body 30 and stops supplying liquid into the pot body 1, thereby preventing water from spraying when the liquid level in the pot body 1 is too high, thereby preventing the water from affecting the ironing effect. The garment steamer proposed in this application can achieve continuous output of steam from the pot body 1 by providing a water level detection component.

[0102] It can be understood that the first water level is lower than the second water level.

[0103] In a specific application, the steam boiler (such as the pot body 1) can be electrically heated to vaporize the water in the boiler to produce steam. The water inlet pressure isolation module (such as the isolator 2) is fixedly connected to the circular hole (such as the through hole 10) at the bottom of the steam boiler by welding or gluing. The water inlet pressure isolation module consists of a screw cap (such as the cover body 26), a sealing ball (such as the sealing part 22) and a bracket 20. Among them, the screw cap is reliably fixed to the bracket 20 by means of threads or gluing, and the sealing ball is placed in the bracket 20, and the sealing ball can move up and down along the internal cavity of the bracket 20 (such as the water inlet channel 200). The material of the sealing ball is selected to have a density greater than that of water, so that the sealing ball can naturally sink in the water due to its own weight. The bracket 20 is fixed to the bottom of the steam boiler by welding or gluing. The bottom of the bracket 20 is designed with an interface (such as a water inlet 202), which is connected to the outlet pipe of the water pump assembly. The water pump assembly consists of a water pump inlet pipe, a water pump (such as a pump body 30) and a water pump outlet pipe. The water pump assembly can be powered on to make the water in the water tank assembly 32 flow into the water pump along the water pump inlet pipe, and then flow into the water inlet pressure isolation module along the water pump outlet pipe, and finally transport the water to the inside of the steam boiler.

[0104] The main working process of this program is:

[0105] When there is sufficient water in the steam boiler and the water pump assembly is not powered on, the sealing ball in the water inlet pressure isolation module is made of a material with a density greater than that of water. Therefore, it can naturally sink in the water due to its own weight, fall along the internal cavity of the bracket 20, and finally rest on the conical surface inside the bracket 20 (such as the sealing fitting area 206). At this time, the sealing ball is pressed down by its own weight, the weight of the water inside the steam boiler, and the pressure generated by the steam in the steam boiler, so that the sealing ball will be tightly pressed against the conical surface inside the bracket 20. As a result, the high-temperature and high-pressure water and steam inside the steam boiler are reliably sealed inside the steam boiler and cannot flow back into the water outlet pipe of the water pump. Therefore, the pressure inside the steam boiler is reliably isolated by the sealing ball, and the water pump assembly will not be directly subjected to the high temperature and high pressure inside the steam boiler.

[0106] When the amount of water inside the steam boiler is small and the water pump assembly is powered on, the water pump will continue to pump water from the water tank assembly 32 to the water pump outlet pipe. As the water pump works, the water inlet pressure in the water pump outlet pipe will gradually increase. When the sealing ball in the water inlet pressure isolation module is subjected to the water inlet pressure of the water pump outlet pipe that is greater than the sealing ball's own gravity, the gravity of the water inside the steam boiler and the pressure generated by the steam in the steam boiler, the sealing ball will leave the conical surface inside the bracket 20 and move upward along the internal cavity of the bracket 20. At this time, the water in the water pump outlet pipe will be able to flow into the internal cavity of the bracket 20 and flow into the steam boiler along the opening on the bracket 20 (such as the water outlet 204), thereby replenishing the steam boiler with water; further, when the water pump assembly is powered off, the water pump stops working, and the water inlet pressure in the water pump inlet pipe will disappear; at this time, the sealing ball will fall again along the internal cavity of the bracket 20 due to the downward pressure of its own gravity, the gravity of the water inside the steam boiler, and the pressure generated by the steam generated by the steam boiler, and finally be tightly pressed on the conical surface inside the bracket 20, so that the high-temperature and high-pressure water and water vapor inside the steam boiler are reliably sealed inside the steam boiler and cannot flow back into the water pump outlet pipe. Therefore, the pressure inside the steam boiler is reliably isolated by the sealing ball.

[0107] The specific benefits of this solution are:

[0108] The water inlet pressure isolation module can reliably isolate the high-temperature and high-pressure water and steam in the steam boiler from the water pump inlet pipeline when the water pump is not operating. Compared with other existing solutions, the water inlet pressure isolation module of this solution has the following outstanding advantages:

[0109] Compared with the solution of adding a one-way valve to the pipe between the water inlet interface of the boiler body and the water outlet of the water pump, the structure of the water inlet pressure isolation module is simpler and can be integrated into the steam boiler, making the product structure simpler and more compact; compared with the solution of integrating a one-way valve or a pressure relief valve on the water pump, the water inlet pressure isolation module of this solution does not require additional functional integration or improvement of the water pump, and a water pump with lower cost and simpler structure can be selected; at the same time, since the water inlet pressure isolation module proposed in this application can effectively isolate the high temperature and high pressure inside the steam boiler, the risk of failure of the water pump inlet pipe and the water pump due to long-term contact with high-temperature and high-pressure water or water vapor is greatly reduced.
