Description
Technical Field

[0002] Garment processing equipment, such as garment steamers, steam treatment machines, and steam irons, uses high-temperature steam to iron clothes. Taking a garment steamer as an example, it mainly consists of a steam generator, a water tank, and an ironing head. During operation, the water tank supplies water to the evaporation chamber of the steam generator. The water is heated and vaporized in the evaporation chamber to produce steam. The steam then acts on the clothes through the ironing head to complete the ironing process.
[0003] However, during the continuous generation of steam in the evaporation chamber, the high-pressure steam formed inside the chamber can easily cause some water to flow back into the water supply tank, thereby interfering with the normal water supply from the water supply tank to the evaporation chamber, causing water supply delay, which in turn disrupts the stability of steam output and affects the ironing effect.

[0021] A third aspect of this application discloses a cooking utensil, comprising: Base; The steam generator as described in the above embodiment is installed on the base; and A cookware is mounted on the base, and the steam outlet supplies steam into the cookware.
[0022] In the steam generator provided in this embodiment, a liquid-sealed balancing chamber is provided in the gas supply bypass. The liquid-sealed balancing chamber is used to balance pressure and regulate water supply flow. The liquid-sealed balancing chamber is connected to the cavity above the liquid level in the evaporation chamber and the water storage chamber, respectively. The liquid-sealed balancing chamber is used to adaptively adjust the water supply flow according to the changes in liquid level and steam pressure in the evaporation chamber. For example, when the garment steamer starts working, the water tank supplies water to the evaporation chamber through the water supply pipe. As the water volume increases, the liquid level in the evaporation chamber gradually rises. When the liquid level reaches the preset level, the liquid in the liquid-sealed balance chamber prevents gas from entering the water storage chamber through the gas replenishment bypass, forming a relatively closed space in the water storage chamber. The water tank then stops supplying water to the evaporation chamber. The evaporation chamber begins to generate steam under the action of the heating element. As the ironing process continues, the water in the evaporation chamber is continuously consumed, and the liquid level gradually drops below the preset level. At this point, the liquid in the liquid-sealed balance chamber no longer blocks the passage between the water storage chamber and the outside atmosphere or the evaporation chamber. Steam from the outside atmosphere or the evaporation chamber enters the cavity above the liquid level in the water storage chamber through the liquid-sealed balance chamber, replenishing the negative pressure area created by the drop in water level. The pressure in the water storage chamber increases, and under the action of the pressure difference, water from the water tank is supplied to the evaporation chamber again through the water supply pipe, ensuring that the water volume in the evaporation chamber is maintained within a reasonable range and guaranteeing continuous and stable steam generation. This automatic gas replenishment method based on changes in the liquid level within the evaporation chamber avoids water supply delays and makes steam output more stable. Alternatively, a certain amount of liquid (such as water or antifreeze) can be pre-stored in the liquid-sealed balance chamber. When the liquid level in the evaporation chamber drops below the preset level, the vapor pressure in the evaporation chamber will increase due to the continuous vaporization of water. When the pressure exceeds the static pressure of the liquid in the liquid-sealed balance chamber, some of the overpressured vapor will pass through the liquid in the liquid-sealed balance chamber. During the process of passing through the liquid, the vapor is cooled down, becoming low-temperature vapor, and replenishes the negative pressure area of the cavity above the liquid level in the water storage chamber. This process not only relieves the pressure in the evaporation chamber, preventing water backflow due to excessive pressure, but also replenishes the air and pressurizes the water storage chamber, promoting the supply of water from the water supply tank to the evaporation chamber and further regulating the water supply flow rate.
[0023] As can be seen, the liquid-sealed balance chamber of this application can adaptively adjust the water supply flow according to the changes in liquid level and pressure in the evaporation chamber, preventing water backflow, ensuring the stability of water supply, thereby improving the continuity and stability of steam output, while reducing the risk of dry burning, making the use of clothing processing equipment more reliable and efficient.

[0033] In daily life, garment processing equipment (such as garment steamers, steam care machines, and steam irons) are widely used to iron clothes to remove wrinkles and improve their smoothness and appearance. Among these, garment steamers, for example, are favored by many users due to their ease of operation and excellent ironing results.
[0034] Garment steamers typically consist of a steam generator, a water tank, and an ironing head. During operation, the water tank continuously supplies water to the evaporation chamber of the steam generator. The evaporation chamber is equipped with a heating element, which heats the water inside to a boiling state, thereby generating high-temperature and high-pressure steam. The generated steam is then transported to the ironing head through pipes, and finally applied to the surface of the clothing by the ironing head, utilizing the high temperature and humidity of the steam to iron the garment.
[0035] However, in actual use, high-pressure steam is continuously generated in the evaporation chamber of the steam generator. This high-pressure steam can easily interfere with the water supply process from the water supply tank to the evaporation chamber. Specifically, the high pressure in the evaporation chamber causes some unheated water to flow back into the water supply tank under pressure, thus hindering the normal water supply and causing a delay in the water supply from the water supply tank to the evaporation chamber. The instability of the water supply directly affects the continuity and stability of steam generation by the steam generator.
[0036] In response to this, this application provides a garment processing device to solve the problem of unstable steam output from the evaporation chamber in existing garment processing devices. The garment processing device of this application will be described in detail below using a garment steamer as an example. Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the internal structure of the steam generator provided in the first embodiment of this application; Figure 2 This is another internal structural diagram of the steam generator provided in the first embodiment of this application; Figure 3 for Figure 2 Enlarged view of point B in the middle.
[0037] The garment processing equipment in this embodiment includes a steam generator and an ironing head.
[0038] The steam generator is used to generate high-temperature steam, and it includes a steam assembly 1 and a water supply assembly 2.
[0039] The steam assembly 1 is the core structure for generating steam. The steam assembly 1 has an evaporation chamber 101, a steam outlet 102, and a water inlet 103. The evaporation chamber 101 is the chamber where water is heated to form steam, and it is connected to the steam outlet 102 and the water inlet 103. The water inlet 103 receives water from the water supply assembly 2. The water is heated and boiled in the evaporation chamber 101 to generate steam, which is then delivered to the ironing head through the steam outlet 102. The evaporation chamber 101 can be made of a high-temperature resistant material (stainless steel, borosilicate glass, etc.) and contains heating elements (heating tubes, heating plates, etc.). When powered on, it can quickly heat the water to above 100°C, causing it to boil and thus continuously output steam.
[0040] The water supply assembly 2 is the part that supplies water to the evaporation chamber 101, and it includes a water supply tank 21, a water supply pipeline 22, and a gas replenishment bypass 23.
[0041] The water tank 21 has a water storage chamber 2101 and a water inlet 2102 connected to the water storage chamber 2101. The water storage chamber 2101 is used to store water, and its capacity can be set according to the usage scenario of the garment processing equipment. For example, the capacity of the water tank 21 of a household garment steamer can be 1-2L. The water inlet 2102 connects the water storage chamber 2101 and the water supply pipe 22. Water flows from the water storage chamber 2101 through the water inlet 2102 and the water supply pipe 22 to the water replenishment port 103 of the evaporation chamber 101.
[0042] The water supply pipe 22 is a channel connecting the water supply tank 21 and the evaporation chamber 101. It can be made of silicone or nylon tubing, possessing heat resistance and flexibility, capable of withstanding water pressure while also allowing for flexible arrangement to fit the overall structural layout of the equipment. When the garment steamer is operating, the water supply pipe 22 delivers water from the water supply tank 21 to the evaporation chamber 101, providing a continuous water source for steam generation.
[0043] The configuration of the gas replenishment bypass 23 is the core of this embodiment in solving the problems of the prior art.
[0044] Specifically, the gas replenishment bypass 23 is equipped with a liquid-sealed balancing chamber 2301, which is used to balance pressure and regulate water supply flow. The liquid-sealed balancing chamber 2301 can be made of transparent plastic or metal. The liquid-sealed balancing chamber 2301 is connected to the cavity above the liquid level in the water storage chamber 2101 and the evaporation chamber 101, respectively. The liquid-sealed balancing chamber 2301 is used to adaptively adjust the water supply flow according to changes in the liquid level and steam pressure in the evaporation chamber 101. It should be noted that, in this embodiment, the liquid level defined in the cavity above the liquid level in the water storage chamber 2101 is the highest liquid level in the water storage chamber 2101.
[0045] In one embodiment, when the garment steamer starts working, the water supply tank 21 supplies water to the evaporation chamber 101 through the water supply pipe 22. As the water volume increases, the liquid level in the evaporation chamber 101 gradually rises. When the liquid level reaches the preset level H, the liquid in the liquid-sealed balance chamber 2301 prevents gas from entering the water storage chamber 2101 via the gas replenishment bypass 23. At this time, a relatively closed space is formed in the water storage chamber 2101, and the water supply tank 21 stops supplying water to the evaporation chamber 101. The evaporation chamber 101 begins to generate steam under the action of the heating element, and the steam is delivered to the ironing head through the steam outlet 102 for ironing. During this process, the sealing effect of the liquid-sealed balance chamber 2301 maintains the pressure balance between the water storage chamber 2101 and the evaporation chamber 101, preventing the high-pressure steam in the evaporation chamber 101 from pushing water back into the water supply tank 21.
[0046] As the ironing process progresses, the water in the evaporation chamber 101 is continuously consumed, and the liquid level gradually drops below the preset liquid level H. At this point, the liquid in the liquid-sealed balance chamber 2301 no longer blocks the passage between the water storage chamber 2101 and the outside atmosphere or the evaporation chamber 101. Steam from the outside atmosphere or the evaporation chamber 101 enters the cavity above the liquid level in the water storage chamber 2101 through the liquid-sealed balance chamber 2301, replenishing the negative pressure area created by the drop in water level. The pressure in the water storage chamber 2101 increases, and under the action of the pressure difference, water in the water supply tank 21 is re-supplyed to the evaporation chamber 101 through the water supply pipe 22, ensuring that the water volume in the evaporation chamber 101 is maintained within a reasonable range, guaranteeing continuous and stable steam generation. This automatic steam replenishment method based on changes in the liquid level in the evaporation chamber 101 avoids water supply delays and makes steam output more stable.
[0047] In addition, the liquid-sealed balancing chamber 2301 can also achieve pressure regulation in another way. A certain amount of liquid (such as clean water) is pre-stored in the liquid-sealed balancing chamber 2301. When the liquid level in the evaporation chamber 101 drops below the preset liquid level H, the steam pressure in the evaporation chamber 101 will increase due to the continuous vaporization of water. When the pressure exceeds the static pressure of the liquid in the liquid-sealed balancing chamber 2301, some of the overpressured steam will pass through the liquid in the liquid-sealed balancing chamber 2301. During the process of passing through the liquid, the steam is cooled down, becomes low-temperature steam, and replenishes the negative pressure area of the cavity above the liquid level in the water storage chamber 2101. This process not only relieves the pressure of the evaporation chamber 101, avoiding water backflow due to excessive pressure, but also replenishes the air and pressurizes the water storage chamber 2101, promoting the water supply tank 21 to supply water to the evaporation chamber 101, and further regulating the water supply flow rate.
[0048] The ironing head is connected to the steam outlet 102 of the evaporation chamber 101, and is used to spray high-temperature steam from the steam hole to act on the surface of the clothing.
[0049] As can be seen, the liquid-sealed balance chamber 2301 of this embodiment can adaptively adjust the water supply flow according to the changes in liquid level and pressure of the evaporation chamber 101, preventing water backflow, ensuring the stability of water supply, thereby improving the continuity and stability of steam output, and reducing the risk of dry burning, making the use of the clothing processing equipment more reliable and efficient.
[0050] Please see Figure 2 , Figure 5 and Figure 6 In some embodiments, the liquid-sealed balancing chamber 2301 and the evaporation chamber 101 are connected by a water circuit, for example, through a pipeline, or they can be directly connected through an interface without a pipeline connection. This allows for bidirectional fluid flow between the liquid-sealed balancing chamber 2301 and the evaporation chamber 101, thereby linking the liquid level changes of the liquid-sealed balancing chamber 2301 and the evaporation chamber 101 and keeping the liquid surface of the liquid-sealed balancing chamber 2301 level with that of the evaporation chamber 101. When the liquid level in the evaporation chamber 101 rises due to water replenishment, the liquid level in the liquid-sealed balancing chamber 2301 will rise synchronously. This interconnected structure utilizes the principle of "communicating vessels": the evaporation chamber 101 and the liquid-sealed balancing chamber 2301 form an interconnected container. When the liquid level in the evaporation chamber 101 rises, the liquid in the evaporation chamber 101 can flow into the liquid-sealed balancing chamber 2301 until the liquid levels of the two reach equilibrium.
[0051] When the garment steamer is started, the water supply tank 21 supplies water to the evaporation chamber 101, causing the liquid level in the evaporation chamber 101 to rise. Due to the communicating vessel effect, the liquid level in the liquid-sealed balance chamber 2301 also rises synchronously. When the liquid level in the liquid-sealed balance chamber 2301 is at the preset liquid level H, the liquid inside seals the passage between the water storage chamber 2101 and the outside atmosphere or the evaporation chamber 101. At this time, the water storage chamber 2101 forms a relatively closed space, the water supply stops, and the evaporation chamber 101 begins to heat and generate steam. This sealed state can prevent the outside atmosphere from interfering with the pressure balance between the water storage chamber 2101 and the evaporation chamber 101, and prevent the high-pressure steam in the evaporation chamber 101 from pushing the water backflow. As the water in the evaporation chamber 101 continuously vaporizes and the liquid level drops, the liquid level in the liquid seal balance chamber 2301 also drops synchronously to below the preset liquid level H due to the communicating vessel effect. The external atmosphere or the steam in the evaporation chamber 101 enters the water storage chamber 2101 through the liquid seal balance chamber 2301, replenishing the negative pressure formed in the cavity above the liquid level in the water storage chamber 2101 due to the drop in water level, causing the pressure in the water storage chamber 2101 to rise. Under the action of the pressure difference, water is supplied to the evaporation chamber 101 again, ensuring a continuous and stable output of steam.
[0052] To further optimize the Qi replenishment pathway, such as Figure 2As shown, in some embodiments, the liquid-sealed balance chamber 2301 has an air inlet 2302 connected to the outside atmosphere. When the liquid level in the liquid-sealed balance chamber 2301 is at a preset liquid level H, the liquid not only blocks the channel between the water storage chamber 2101 and the outside atmosphere, but also blocks the channel between the air inlet 2302 and the water storage chamber 2101, ensuring the sealing of the water storage chamber 2101, maintaining pressure balance, and avoiding interference from external gases. When the liquid level in the evaporation chamber 101 drops, and the liquid level in the liquid-sealed balance chamber 2301 simultaneously drops below the preset liquid level H, the channel between the air inlet 2302 and the water storage chamber 2101 is opened, and the outside atmosphere enters the liquid-sealed balance chamber 2301 through the air inlet 2302 and then flows into the water storage chamber 2101, thus achieving gas replenishment. The air inlet 2302 makes air replenishment more direct and efficient, reduces gas flow resistance, can quickly balance the negative pressure in the water storage chamber 2101, accelerate the water supply speed from the water supply tank 21 to the evaporation chamber 101, improve the response speed of steam output, and avoid the problem of steam interruption caused by untimely air replenishment.
[0053] In some embodiments, such as Figure 2 As shown, the air supply bypass 23 in this embodiment includes a balancing component 231 and a guide pipe 232. The balancing component 231 has a liquid-sealed balancing chamber 2301, and the balancing component 231 also has an air inlet 2302, a first interface 2304 and a second interface 2305. The first interface 2304 and the second interface 2305 are both connected to the liquid-sealed balancing chamber 2301. The first interface 2304 is connected to the cavity above the liquid level in the water storage chamber 2101.
[0054] The balancing component 231 can be made of high-temperature resistant material to ensure stable operation in a steam environment. The two ends of the guide pipe are connected to the evaporation chamber 101 and the second interface 2305, respectively, to connect the evaporation chamber 101 and the liquid-sealed balancing chamber 2301. This is used to transmit the liquid level change of the evaporation chamber 101 to the liquid-sealed balancing chamber 2301, so that the liquid-sealed balancing chamber 2301 can sense the working status of the evaporation chamber 101 in real time. For example, when the liquid level in the evaporation chamber 101 rises or falls, the liquid flow in the guide pipe 232 drives the liquid level in the liquid-sealed balancing chamber 2301 to change synchronously.
[0055] In some embodiments, the air replenishment bypass 23 further includes an air guide pipe 233. One end of the air guide pipe 233 is connected to the first interface 2304, and the other end passes through the water storage cavity, with its end higher than the highest liquid level of the water storage cavity 2101 to connect to the cavity above the liquid level in the water storage cavity 2101. This design prevents water in the water storage cavity 2101 from flowing back into the liquid seal balance cavity 2301. When air replenishment is required, outside air enters the liquid seal balance cavity 2301 through the air inlet 2302, and is then transported to the cavity above the liquid level in the water storage cavity 2101 through the air guide pipe 233. The height setting of the end of the air guide pipe 233 prevents water in the water storage cavity 2101 from entering the air guide pipe 233 when it is shaking or full, ensuring a stable and reliable air replenishment process and improving the working stability of the equipment in moving or tilting states.
[0056] In some embodiments, a ventilation channel is provided inside the water supply tank 21. One end of the ventilation channel is connected to the first interface 2304, and the other end is connected to the cavity above the liquid level (the highest liquid level in the water storage chamber 2101) in the water storage chamber 2101. The ventilation channel is formed inside the inner wall of the water supply tank 21.
[0057] In this embodiment, the ventilation channel is integrated into the inner wall of the water supply tank 21. On the one hand, the channel is formed by the structure of the water supply tank 21 itself, which reduces the number of parts, reduces assembly complexity and leakage risk. On the other hand, the channel is hidden in the inner wall, which avoids interference with other structures inside the water supply tank 21. At the same time, the protective function of the tank wall can be used to reduce interference and loss during airflow, making the air replenishment efficiency more stable.
[0058] In some embodiments, such as Figure 2 As shown, a one-way air inlet valve 234 is provided at the air inlet 2302 of the balancing component 231. The one-way air inlet valve 234 is unidirectionally open in the direction of external air entering the liquid-sealed balancing chamber 2301. The one-way air inlet valve 234 only allows external air to enter the liquid-sealed balancing chamber 2301, while preventing gas or vapor in the liquid-sealed balancing chamber 2301 from overflowing from the air inlet 2302. When the liquid level in the liquid-sealed balancing chamber 2301 drops below the preset liquid level H and air needs to be replenished, external air enters through the one-way air inlet valve 234. At the same time, the one-way air inlet valve 234 can prevent gas or vapor in the water storage chamber 2101 from flowing back into the outside, maintaining the pressure balance of the water storage chamber 2101, and further enhancing the safety and reliability of the equipment.
[0059] In some embodiments, such as Figure 5 and Figure 6 As shown, different from Figure 2 In the illustrated embodiment, the air inlet 2302 is directly connected to the outside atmosphere. In this embodiment, the liquid-sealed balanced air inlet 2302 is connected to the evaporation chamber 101, forming a steam replenishment path.
[0060] Specifically, when the liquid level in the evaporation chamber 101 is at the preset liquid level H, due to the principle of communicating vessels, the liquid level in the liquid-sealed balance chamber 2301 is also at the preset liquid level H. At this time, the liquid in the liquid-sealed balance chamber 2301 blocks the passage between the air inlet 2302 and the water storage chamber 2101. As the evaporation process proceeds, when the liquid level drops below the preset liquid level H, the liquid-sealed balance chamber 2301 becomes connected to the water storage chamber 2101 through the air inlet 2302, and some steam enters the cavity above the liquid level in the water storage chamber 2101 through the liquid-sealed balance chamber 2301. In this way, the steam entering the cavity above the liquid level in the water storage chamber 2101 increases the pressure inside the cavity, pushing the water supply tank 21 to supply water to the evaporation chamber 101, thereby improving the water supply efficiency.
[0061] In some embodiments, continue reading Figure 5 and Figure 6 In this embodiment, the gas replenishment bypass 23 includes a balance cover 235 and a gas guide pipe 233. Specifically, the balance cover 235 is installed on the outer wall of the evaporation chamber 101 and cooperates with the outer wall of the evaporation chamber 101 to form a liquid-sealed balance chamber 2301. The liquid-sealed balance chamber 2301 also has a connecting port 2303, which is located at the bottom of the liquid-sealed balance chamber 2301 and is used to connect the evaporation chamber 101 and the liquid-sealed balance chamber 2301 to keep the liquid levels of the two consistent. The air inlet 2302 is higher than the connecting port 2303 to ensure that it is blocked by liquid when the liquid level is at the preset liquid level H. When the liquid level drops, steam enters the liquid-sealed balance chamber 2301 through the air inlet 2302 and is then transported to the cavity above the liquid level in the water storage chamber 2101 through the gas guide pipe 233.
[0062] In this embodiment, the outer wall of the evaporation chamber 101 is used as part of the liquid seal balance chamber 2301, which reduces the additional space occupied, makes the structure more compact, and facilitates disassembly and maintenance.
[0063] In some embodiments, such as Figure 2 and Figure 5 As shown, the steam assembly 1 includes a chassis 11, a heating element, and a steam hood 12. The chassis 11 is the basic support for the steam generator. The heating element is installed on the chassis 11 and is used to heat the liquid in the evaporation chamber 101 to form steam.
[0064] A steam hood 12 is mounted on a chassis 11 and mates with the chassis 11 to form an evaporation chamber 101. The steam hood 12 includes a main body 121 and a narrowing section 122, which are connected sequentially along the steam flow direction (from bottom to top). The main body 121 has a larger diameter to store more liquid and receive water from the water inlet 103. The narrowing section 122 gradually decreases in diameter, forming a Venturi-like structure to accelerate steam flow. When steam flows from the main body 121 to the narrowing section 122, the flow velocity increases, increasing the steam output power. The water inlet 103 is located on the main body 121 to ensure that water is directly supplied to the liquid storage area, avoiding interference with the steam flow path. The steam outlet 102 is located at the free end of the narrowing section 122, allowing high-speed steam to directly enter the ironing head. A gas bypass 23 is connected to the main body 121, facilitating the formation of a communicating vessel structure between the evaporation chamber 101 and the liquid-sealed balance chamber 2301, thereby aiding in pressure balance.
[0065] In this embodiment, the accelerating effect of the narrowing section 122 makes the steam jet more powerful and improves the ironing effect; the large capacity design of the main body 121 provides a more stable buffer for liquid level changes and reduces the steam pressure fluctuation caused by water supply fluctuations; the connection position between the gas replenishment bypass 23 and the main body 121 facilitates the formation of a communicating vessel structure between the evaporation chamber 101 and the liquid seal balance chamber 2301, further improving the continuity of steam output.
[0066] In some embodiments, such as Figure 7 As shown, different Figure 2 and Figure 5 The liquid seal balance chamber 2301 shown in this embodiment operates on the principle of a communicating vessel. The liquid seal balance chamber 2301 can adjust the water supply flow rate according to the pressure change of the evaporation chamber 101.
[0067] Specifically, when the evaporation chamber 101 is operating normally and the liquid level is at the preset level H, the liquid in the liquid-sealed balance chamber 2301 seals the passage between the water storage chamber 2101 and the evaporation chamber 101 to prevent steam leakage. As the liquid in the evaporation chamber 101 continuously vaporizes, and the liquid level drops below the preset level H, the steam pressure in the evaporation chamber 101 increases due to continuous heating. When the steam pressure exceeds the static pressure of the liquid in the liquid-sealed balance chamber 2301, some high-pressure steam will break through the liquid seal and pass through the liquid in the liquid-sealed balance chamber 2301. During the process of passing through the liquid, the steam comes into full contact with the liquid and is cooled down. Some of the steam liquefies into water and replenishes the liquid-sealed balance chamber 2301, while the remaining low-temperature steam enters the negative pressure area of the cavity above the liquid level in the water storage chamber 2101. In this way, the overpressure steam in the evaporation chamber 101 is released, reducing the pressure inside the evaporation chamber 101 and preventing water backflow caused by high pressure. In addition, after the low-temperature steam enters the water storage chamber 2101, it increases the pressure in the cavity above the liquid level in the water storage chamber 2101, pushing the water supply tank 21 to supply water to the evaporation chamber 101, balancing the negative pressure caused by the drop in liquid level, thereby promoting the water supply speed and ensuring the continuity of steam output.
[0068] In some embodiments, such as Figure 7 As shown, the gas supply bypass 23 in this embodiment includes a balancing component 231, a guide pipe 232, and a gas guide pipe 233. A liquid-sealed balancing chamber 2301 is formed inside the balancing component 231. The liquid-sealed balancing chamber 2301 inside the balancing component 231 can be pre-filled with liquid (usually clean water) to achieve preliminary sealing of the water storage chamber 2101 and the evaporation chamber 101.
[0069] One end of the guide pipe 232 is connected to the evaporation chamber 101, and the connection point is located above the liquid level in the evaporation chamber 101; the other end extends into the liquid-sealed balance chamber 2301, and the port is lower than the liquid level in the liquid-sealed balance chamber, thus forming a liquid-sealed structure. During the initial startup of the equipment, when the liquid level in the evaporation chamber 101 is at the preset liquid level H, the portion of the guide pipe 232 submerged in the liquid can, with the help of the liquid's sealing properties, block the passage between the water storage chamber 2101 and the evaporation chamber 101. At this time, the water storage chamber 2101 and the evaporation chamber 101 are only connected by the water supply pipe 22. As the water in the evaporation chamber 101 continuously vaporizes and the liquid level drops below the preset liquid level H, the steam pressure in the evaporation chamber 101 increases. The high-pressure steam breaks through the liquid seal through the guide pipe 232 and passes through the liquid in the liquid-sealed balance chamber 2301. It should be noted that the connection between the guide pipe 232 and the evaporation chamber 101 is located above the liquid level in the evaporation chamber 101, and the defined liquid level is the highest liquid level in the evaporation chamber 101.
[0070] One end of the gas guide pipe 233 connects to the cavity above the liquid level in the liquid-sealed balance chamber 2301, and the other end connects to the cavity above the liquid level (the highest liquid level in the water storage chamber 2101), forming a gas channel independent of the water supply pipe 22. When high-pressure steam enters the liquid-sealed balance chamber 2301, some of the steam cools and liquefies within the chamber, replenishing the liquid consumed by the liquid-sealed balance chamber 2301; the unliquefied steam enters the cavity above the liquid level in the water storage chamber 2101 through the gas guide pipe 233, replenishing the negative pressure formed in the water storage chamber 2101 due to the drop in water level. During this process, the entry of steam increases the pressure in the water storage chamber 2101. Under the action of the pressure difference, the water in the water supply tank 21 flows more smoothly into the evaporation chamber 101 through the water supply pipe 22, achieving a stable water supply. The entire process can be automatically regulated without additional control components, ensuring the continuity of steam output and avoiding the risk of dry burning.
[0071] In some embodiments, such as Figure 7 As shown, the structure of the steam assembly 1 in this embodiment is similar to... Figure 2 and Figure 5 The structure of the embodiment shown is similar, but the gas supply bypass 23 is connected to the narrowing portion 122 of the steam hood 12.
[0072] In this embodiment, the gas replenishment bypass 23 is connected to the narrowing section 122. When the evaporation chamber 101 is working, the steam is accelerated by the narrowing section 122 and then output from the steam outlet 102. As the evaporation process proceeds, the liquid level drops below the preset liquid level H, and the steam pressure in the evaporation chamber 101 increases due to continuous heating. When the pressure exceeds the static pressure of the liquid in the liquid seal balance chamber 2301, some high-pressure steam enters the liquid seal balance chamber 2301, breaks through the liquid seal, and enters the cavity above the liquid level in the water storage chamber 2101 through the gas guide pipe 233.
[0073] On the one hand, steam is discharged from the high-pressure area of the narrowing section 122, which can more efficiently release the overpressure steam in the evaporation chamber 101 and prevent water from flowing back to the water supply tank 21 due to excessive pressure. On the other hand, the steam entering the water storage chamber 2101 replenishes the negative pressure caused by the drop in water level, increasing the pressure inside the water storage chamber 2101 and pushing the water supply tank 21 to supply water to the evaporation chamber 101 through the water supply pipe 22. Due to the flow velocity characteristics of the narrowing section 122, the steam discharge rate is positively correlated with the pressure change inside the evaporation chamber 101. The higher the pressure, the greater the amount of steam discharged, and the more obvious the gas replenishment and pressurization effect, thereby achieving the purpose of adaptively adjusting the water supply flow according to pressure changes.
[0074] In some embodiments, such as Figure 2 and Figure 3As shown, the water supply tank 21 also has an installation port 2103, and the installation port 2103 and the water supply port 2102 are located on the same side of the water supply tank 21. This same-side layout reduces pipe crossings within the equipment, making the overall structure more compact. The air duct 233 extends from the installation port 2103 into the water storage chamber 2101, then extends towards the cavity above the liquid level in the water storage chamber 2101. Its end is higher than the highest liquid level in the water storage chamber 2101 to prevent water in the water storage chamber 2101 from entering the air duct 233 when the chamber is agitated or full, ensuring that the air supply channel remains unobstructed. Simultaneously, the connection between the air duct 233 and the installation port 2103 uses a sealed structure (such as a silicone sealing ring), which not only ensures the sealing of the water storage chamber 2101 but also buffers the displacement of the air duct 233 caused by equipment vibration, improving long-term reliability. In this way, the gas guide tube 233 can stably transport the gas from the liquid seal balance chamber 2301 to the cavity above the liquid level in the water storage chamber 2101, and together with the water supply from the water supply pipe 22, form an efficient gas-liquid synergistic regulation mechanism.
[0075] In some embodiments, the water supply assembly 2 further includes a water tank base 24, and the water supply tank 21 is detachably installed on the water tank base 24, with the installation and removal direction being vertical, consistent with the extension direction of the vent pipe 233. This greatly improves the ease of installation and removal of the water supply tank 21: when water needs to be added or the water supply tank 21 needs cleaning, the user can lift the water supply tank 21 upwards along the axial direction of the vent pipe 233 without additional disassembly of the vent pipe 233 or the water supply line 22; during installation, simply align the water supply tank 21 with the positioning structure of the water tank base 24 and lower it vertically to complete the connection. The vent pipe 233 acts as a "guide rail," preventing misalignment of the water supply tank 21 during installation and ensuring precise connection between the water inlet 2102 and the water supply line 22, and between the installation port 2103 and the vent pipe 233. Furthermore, the detachable design facilitates separate cleaning of the inside of the water supply tank 21, reducing the impact of scale buildup on water supply stability and indirectly ensuring the continuity of steam output.
[0076] In some embodiments, the air duct 233 extends into the water supply tank 21 via the water tank base 24, and the periphery of the air duct 233 is sealed to the water tank base 24 (e.g., with an interference fit or a sealing ring). This sealed connection between the air duct 233 and the water tank base 24 also prevents external dust or liquid from entering the equipment through the gap between them, while preventing gas leakage from the water storage chamber 2101 and ensuring stable transmission of the air supply pressure. Furthermore, the air duct 233 and the water tank base 24 form a single unit; when the water supply tank 21 is removed from the water tank base 24, the air duct 233 remains fixed to the water tank base 24, preventing pipe pulling or seal failure caused by the movement of the air duct 233 with the water supply tank 21.
[0077] Furthermore, in some embodiments, the water tank base 24 is provided with an installation groove 2401 for the air guide pipe 233 to extend into. The installation groove 2401 is positioned opposite to the installation port 2103 of the water supply tank 21. The air guide pipe 233 passes through the installation groove 2401 and the installation port 2103 in sequence, and the periphery of the air guide pipe 233 is sealed to the groove wall of the installation groove 2401 by a sealing element (such as an O-ring). The installation groove 2401 provides a positioning reference for the air guide pipe 233, reducing the coaxiality error between the air guide pipe 233 and the installation port 2103, and avoiding sealing failure or pipe wear caused by eccentricity. When the water supply tank 21 is installed on the water tank base 24, the air guide pipe 233 passes through both the installation groove 2401 and the installation port 2103, which ensures both the compactness of the structure and enhances the overall sealing performance. This design also facilitates the individual replacement and maintenance of the air duct 233. When the air duct 233 becomes aged or blocked, it can be removed simply by disassembling the water supply tank 21, without having to disassemble the entire water supply assembly 2, thus reducing maintenance costs.
[0078] In some embodiments, such as Figure 1 and Figure 4 As shown, the water supply tank 21 and the water tank base 24 are connected and sealed quickly through a plug-in structure, which further optimizes the ease of disassembly and assembly and the stability of water supply of the water supply component 2.
[0079] Specifically, the water supply tank 21 includes a tank body 211 and a first insertion part 212. The tank body 211 serves as the carrier of the water storage chamber 2101 and can be made of materials such as food-grade PP plastic or polyethylene PE. Its shape can be designed as a cuboid or cylinder according to the overall layout of the equipment to maximize space utilization. The first insertion part 212 is located at the bottom of the tank body 211 and is fixed to the tank body 211 by a detachable sealed connection or an integral molding process to ensure the airtightness of the water storage chamber 2101. The interior of the first insertion part 212 is provided with a water supply port 2102 that communicates with the water storage chamber 2101.
[0080] The water tank base 24 includes a base body 241 and a second insertion part 242. The base body 241 provides support for the entire water supply assembly 2 and can be connected and fixed to the chassis 11. The second insertion part 242 is fixedly connected to the base body 241 and has an outlet channel 2402 inside, which connects to the water supply port 2102 and the water supply pipe 22. When the first insertion part 212 and the second insertion part 242 are inserted together, the water supply port 2102 and the outlet channel 2402 are connected, and a sealing ring is provided between the first insertion part 212 and the second insertion part 242 to achieve a seal, which ensures the continuity of the water flow channel and prevents water from seeping out from the joint gap.
[0081] The plug-in structure in this embodiment has two advantages. First, the plug-in design eliminates the need for rotation or locking when connecting the water supply tank 21 to the water tank base 24; only axial thrust is required to complete the connection. Combined with the vertical assembly / disassembly direction described above, this further shortens the assembly / disassembly time. Second, the cooperation between the first plug-in part 212 and the second plug-in part 242 ensures the coaxiality of the water supply port 2102 and the water outlet channel 2402, reducing water flow resistance and making the water supply speed more stable.
[0082] In addition, the plug-in structure facilitates later maintenance. When the sealing ring ages, the sealing ring on the first plug-in part 212 or the second plug-in part 242 can be replaced simply by pulling out the water supply tank 21, without the need for professional tools, thus reducing maintenance costs.
[0083] It is understandable that the above Figure 1 and Figure 2 The structure and connection method of the air duct 233, water supply tank 21 and water tank base 24 in the embodiment are also applicable to Figure 5 and Figure 7 The steam generator of the embodiment shown, Figure 5 and Figure 7 The steam generator shown in the embodiment may also include Figure 1 and Figure 2 The structure of the air duct 233, water supply tank 21 and water tank base 24 in the embodiment.
[0084] This application further proposes a cooking appliance, which can be an electric steamer, a steam oven, a steam stew pot, etc. Taking an electric steamer as an example, the cooking appliance includes a base, a steam generating device as described in the above embodiments, and a pot.
[0085] The base is the supporting structure of the cooking appliance, providing a platform for the steam generator and cookware. The base contains control circuits, power interfaces, and other components used to regulate the operating status of the steam generator (such as heating power and operating time).
[0086] The steam generator is installed on the base, and the high-temperature and high-pressure steam generated by its evaporation chamber 101 is delivered to the cookware through the steam outlet 102. The cookware is installed on the base, and the food is placed inside the cookware. When the high-temperature steam enters the cookware, it will flow around the food and release heat, thereby realizing the cooking functions such as steaming, heating, or keeping the food warm.
[0087] The cooking appliance in this embodiment utilizes the stable operation of the steam generator to achieve efficient and consistent cooking results.
[0088] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
