Description

[Technical Field]

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an electric steamer. [Background Technology]

[0002] Prior art CN222459749 discloses a steam generating device and a steam-powered household appliance, which includes a water tank assembly having a steam chamber, a water supply chamber, and a mounting groove. The mounting groove is formed in the bottom wall of the water supply chamber, and the mounting groove and the bottom wall of the steam chamber are lower than the bottom wall of the water supply chamber. The steam chamber and the water supply chamber are connected through the mounting groove. A heating element is disposed below the steam chamber. A water control valve is detachably assembled in the mounting groove, and the water control valve includes a float valve structure for controlling the on / off connection between the steam chamber and the water supply chamber. When the steam appliance is an electric steamer, its water replenishment chamber is located below the steamer assembly. As a result, the water in the replenishment chamber is inevitably contaminated during the cooking process, such as by dripping oil, food residue, limescale, flocculent matter, etc. These contaminants will enter the water control valve and affect the float's movement, causing the water control valve to lose its water control function. This requires users to clean the water control valve, steam chamber, water replenishment chamber, and installation slot in a timely manner, increasing the cleaning frequency and reducing the user experience. [Utility Model Content]

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an electric steamer that can effectively reduce the entry of pollutants into the one-way water passage, thereby reducing the impact of pollutants on the float's floating and thus effectively extending the float's service life.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An electric steamer includes a base, a steaming basket assembly mounted on the base, and an external water tank. The base includes a water storage chamber, a steam generating chamber, and a heating element located at the bottom of the steam generating chamber. A partition rib is provided between the water storage chamber and the steam generating chamber to block the communication between the water storage chamber and the steam generating chamber on both sides of the partition rib. The external water tank includes a water replenishment chamber. A bidirectional water passage is provided between the water storage chamber and the water replenishment chamber. A unidirectional water passage is provided between the water replenishment chamber and the steam generating chamber to allow water to flow from the water replenishment chamber to the steam generating chamber. A float is provided in the unidirectional water passage, and the float floats with the water level to control the opening and closing of the unidirectional water passage.

[0006] In the aforementioned electric steamer, the bidirectional water passage is located near the bottom of the side wall of the water storage chamber.

[0007] In the aforementioned electric steamer, the base further includes a housing and a float shell exposed on the outer surface of the housing. The float shell forms the one-way water passage, which includes a water inlet communicating with the water replenishment chamber and a water outlet communicating with the steam generation chamber. The water inlet is located above the float, and the float floats to open and close the water inlet.

[0008] In the above-mentioned electric steamer, the base also includes a mounting groove and a partition frame disposed in the mounting groove. The one-way water passage is disposed between the partition frame and the bottom of the mounting groove. The one-way water passage includes a water inlet disposed on the partition frame to communicate with the water replenishment chamber and a water outlet to communicate with the steam generating chamber. The water inlet is located above the float, and the float floats to open and close the water inlet.

[0009] In the aforementioned electric steamer, an interval partition structure is provided between the mounting slot and the water replenishment chamber, and the interval partition structure is provided with a water passage connecting the mounting slot and the water replenishment chamber; the interval partition structure is a vertically extending partition plate located inside the external water tank, the partition plate dividing the interior of the external water tank into the water replenishment chamber and the mounting slot; or the interval partition structure is the shell of the base, the top of the shell being recessed downward to form the mounting slot; or the interval partition structure is the bottom wall of the external water tank, the mounting slot being located on one side of the outer surface of the bottom wall of the external water tank.

[0010] In the electric steamer described above, the divider and the float are detachably connected to form a float valve, and the float valve is detachably installed in the mounting slot.

[0011] In the aforementioned electric steamer, the divider rack includes a plurality of circumferentially spaced elastic buckles, each elastic buckle having an inwardly extending latching protrusion, and the float being positioned between the latching protrusion and the water inlet.

[0012] In the electric steamer described above, the groove of the mounting slot is exposed on the outer surface of the base, and the float valve is connected to a cover plate, which covers the groove.

[0013] In the above-mentioned electric steamer, the water storage chamber is arranged around the steam generating chamber; or the water storage chamber is located between the steam generating chamber and the external water tank.

[0014] In the electric steamer described above, a connecting pipe is provided on the outer side of the bottom wall of the water storage chamber. One end of the connecting pipe is connected to the steam generating chamber, and the other end is connected to the water replenishment chamber through the one-way water passage.

[0015] The beneficial effects of this utility model are:

[0016] 1. In this utility model, before operation, when the steamer assembly is not placed, the user can simultaneously add water to the water storage chamber and the water replenishment chamber of the external water tank. During normal operation of the electric steamer, when the one-way water passage is in a connected state, the water in the water replenishment chamber first flows into the steam generating chamber through the one-way water passage. Since the water replenishment chamber is located on the outside, the water in the water replenishment chamber is less likely to be contaminated. When the water level in the water replenishment chamber drops, the water storage chamber can replenish water to the water replenishment chamber through the two-way water passage. If the water in the water storage chamber is contaminated by pollutants, the two-way water passage can also block the pollutants flowing into the water replenishment chamber, thereby reducing the amount of pollutants entering the water replenishment chamber and preventing pollutants from accumulating in the one-way water passage and affecting the float's floating, thus causing it to lose its water control function and effectively extending the life of the float. This design extends the lifespan of the water supply while reducing the frequency of cleaning. When the water level in the storage chamber is low, users can add clean water to the external water tank's replenishment chamber. Because the steam generating chamber and the replenishment chamber are connected by a one-way water passage that allows water to flow from the replenishment chamber to the steam generating chamber, and the flow is controlled by the float, most of the excess water will enter the storage chamber through the two-way water passage. At this time, contaminants that have entered the replenishment chamber will be diluted or returned to the storage chamber, making the water in the replenishment chamber relatively cleaner. This ensures that the one-way water passage prioritizes the use of cleaner water, further reducing the impact of contaminants on the float and improving the float's lifespan. Finally, this invention utilizes the buoyancy and weight of the float to control the flow of the one-way water passage, eliminating the need for additional drive components and resulting in lower production costs.

[0017] 2. The bidirectional water passage is located near the bottom of the side wall of the water storage chamber. Since oil floats on the water surface, this design effectively prevents surface oil from entering the bidirectional water passage, keeping the water in the water supply chamber clearer and cleaner.

[0018] 3. The base also includes a housing and a float housing exposed on the outer surface of the housing. The float housing forms a one-way water passage, which includes an inlet connected to the water supply chamber and an outlet connected to the steam generation chamber. The inlet is located above the float, and the float's movement opens and closes the inlet. This design eliminates the need to alter the existing internal structure of the housing; the float housing is simply installed on the outer surface, reducing product modification costs. Furthermore, the float can be disassembled and reassembled without opening the external water tank or housing, facilitating cleaning or replacement by the user.

[0019] 4. The base also includes a mounting slot and a partition frame located within the mounting slot. A one-way water passage is located between the partition frame and the bottom of the mounting slot. The one-way water passage includes an inlet located on the partition frame that communicates with the water supply chamber, and an outlet that communicates with the steam generation chamber. The inlet is located above the float, and the float moves to open and close the inlet. This design, by providing a mounting slot to accommodate the float and placing the partition frame above the float, allows the float to be concealed, thus improving the product's appearance.

[0020] 5. A partition structure is provided between the installation slot and the water replenishment chamber. This partition structure has a water passage connecting the installation slot and the water replenishment chamber. This design further isolates and blocks contaminants, thus improving the service life of the float valve. The partition structure is a vertically extending partition inside the external water tank, dividing the interior of the external water tank into the water replenishment chamber and the installation slot. This design allows the installation slot to be concealed by a water tank cover fitted onto the external water tank body, further improving the product's appearance. Alternatively, the partition structure can be the housing of the base, and the housing... The top is recessed downwards to form the mounting groove. This design allows for the assembly of the float and the divider without opening the external water tank. When the float and the divider are detachable within the mounting groove, they can also be disassembled without opening the external water tank. Alternatively, the partition structure can be the bottom wall of the external water tank, with the mounting groove located on one side of the outer surface of the bottom wall. This design allows the float and the divider to be positioned below the water supply chamber, facilitating the flow of water in the chamber to the unidirectional water passage. Furthermore, the mounting groove can be concealed by the water tank cover, further enhancing the product's appearance.

[0021] 6. The separator and float are detachably connected to form a float valve, which is detachably installed in the mounting slot. This design allows the float to be removed along with the separator when it is taken out of the mounting slot, thus enabling the disassembly and assembly of the float valve and the mounting slot, as well as the disassembly and assembly of the various components of the float valve. This achieves the effects of no water retention, easy cleaning, and safety and hygiene.

[0022] 7. The divider includes multiple circumferentially spaced elastic buckles, each with an inwardly extending locking protrusion. The float is positioned between the locking protrusion and the water inlet. This design facilitates the assembly and disassembly of the float and the divider, while also guiding the float's movement through the elastic buckles to prevent it from drifting and failing to close the water inlet. Furthermore, the locking protrusion lowers the float, ensuring that a water inlet gap is formed between the float and the bottom wall of the mounting groove when the float is at its lowest position. This allows water flowing into the one-way water passage into the water inlet gap when the float is at its lowest position, causing the float to rise due to buoyancy and thus enabling it to close the water inlet and control the water flow.

[0023] 8. The groove of the mounting slot is exposed on the outer surface of the base. The float valve is connected to a cover plate, which covers the groove. This design not only prevents external debris from entering the mounting slot and contaminating the water, but also allows the float valve to be removed and cleaned without opening the external water tank lid by pulling the cover plate, making the operation simpler.

[0024] 9. The water storage chamber is arranged around the steam generating chamber; or the water storage chamber is located between the steam generating chamber and the external water tank. This design facilitates the machining and forming of the water storage chamber and the steam generating chamber, and reduces the machining difficulty of the base.

[0025] 10. A connecting pipe is provided on the outer side of the bottom wall of the water storage chamber. One end of the connecting pipe is connected to the steam generating chamber, and the other end is connected to the water supply chamber through the one-way water passage. This design allows the connecting pipe to be hidden below the water storage chamber, thus avoiding its exposure and reducing the appearance of the product.

[0026] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. [Attached Image Description]

Detailed Implementation Methods

[0042] This utility model provides an electric steamer, including a base, a steaming basket assembly and an external water tank mounted on the base. The base includes a water storage chamber, a steam generating chamber, and a heating element located at the bottom of the steam generating chamber. A partition rib is provided between the water storage chamber and the steam generating chamber to block the communication between the water storage chamber and the steam generating chamber on both sides of the partition rib. The external water tank includes a water replenishment chamber. A bidirectional water passage is provided between the water storage chamber and the water replenishment chamber. A unidirectional water passage is provided between the water replenishment chamber and the steam generating chamber to allow water to flow from the water replenishment chamber to the steam generating chamber. A float is provided in the unidirectional water passage, and the float floats with the water level to control the opening and closing of the unidirectional water passage.

[0043] In this invention, before operation, when the steamer assembly is not placed, the user can simultaneously add water to both the water storage chamber and the water replenishment chamber of the external water tank. During normal operation of the electric steamer, when the one-way water passage is connected, the water in the water replenishment chamber first flows into the steam generating chamber through the one-way water passage. Since the water replenishment chamber is located on the outside, the water in the water replenishment chamber is less susceptible to contamination. When the water level in the water replenishment chamber drops, the water storage chamber can replenish the water replenishment chamber through the two-way water passage. If the water in the water storage chamber is contaminated by pollutants, the two-way water passage provides some barrier, thus blocking the pollutants flowing into the water replenishment chamber. This reduces the amount of pollutants entering the water replenishment chamber, preventing pollutants from accumulating in the one-way water passage and affecting the float's buoyancy, thereby causing it to lose its water control function and effectively extending the float's lifespan. This design extends the lifespan of the float and reduces the frequency of cleaning. When the water level in the storage chamber is low, users can add clean water to the external water tank's replenishment chamber. Because the steam generating chamber and the replenishment chamber are connected by a one-way water passage that allows water to flow from the replenishment chamber to the steam generating chamber, and the flow is controlled by the float, most of the excess water will enter the storage chamber through the two-way water passage. At this time, contaminants that have entered the replenishment chamber will be diluted or returned to the storage chamber, making the water in the replenishment chamber relatively cleaner. This ensures that the one-way water passage prioritizes the use of cleaner water, further reducing the impact of contaminants on the float and improving the float's lifespan. Finally, this invention utilizes the buoyancy and weight of the float to control the flow of the one-way water passage, eliminating the need for additional drive components and resulting in lower production costs.

[0045] Example 1

[0046] like Figures 1 to 6As shown, the electric steamer in this embodiment includes a base 100, an external water tank 200, and a steamer assembly 300 that can be placed on the base 100. The base 100 includes a housing 110 and structures such as a heating element 120 and a circuit board installed inside the housing 110. The housing 110 includes a water storage chamber 111 with an open top and a steam generating chamber 112. The heating element 120 is located at the bottom of the steam generating chamber 112 to heat the water in the steam generating chamber 112 to form steam. After the steamer assembly 300 is placed on the base 100, it covers the water storage chamber 111 and the steam generating chamber 112. 12. A partition rib 113 is provided between the water storage chamber 111 and the steam generating chamber 112 to block the communication between the water storage chamber 111 and the steam generating chamber 112 on both sides of the partition rib 113. The external water tank 200 includes a water replenishment chamber 210. A bidirectional water passage 001 is provided between the water storage chamber 111 and the water replenishment chamber 210. The bidirectional water passage 001 is a channel that allows water to flow in both directions, that is, water in the water storage chamber 111 can flow to the water replenishment chamber 210 through the bidirectional water passage 001, and water in the water replenishment chamber 210 can also flow to the water storage chamber 111 through the bidirectional water passage 001. A unidirectional water passage 002 is provided between the water replenishment chamber 210 and the steam generating chamber 112, allowing water to flow from the water replenishment chamber 210 to the steam generating chamber 112. A float 400 is provided in the unidirectional water passage 002. The float 400 floats with the water level to control the opening and closing of the unidirectional water passage 002.

[0047] In this embodiment, before operation, when the steamer assembly 300 is not placed, the user can simultaneously add water to the water storage chamber 111 and the water replenishment chamber 210 of the external water tank 200. During normal operation of the electric steamer, when the one-way water passage 002 is in a connected state, the water in the water replenishment chamber 210 first flows into the steam generating chamber 112 through the one-way water passage 002. Since the water replenishment chamber 210 is located on the outside, the water in the water replenishment chamber 210 is less likely to be contaminated. When the water level in the water replenishment chamber 210 drops, the water storage chamber 111 can replenish water to the water replenishment chamber 210 through the two-way water passage 001. If the water in the water storage chamber 111 is contaminated by pollutants, due to the certain blocking effect of the two-way water passage 001, the pollutants flowing into the water replenishment chamber 210 can also be blocked, that is, the amount of pollutants entering the water replenishment chamber 210 is reduced, avoiding the accumulation of pollutants in the one-way water passage 002, which would affect the float 400's floating and cause it to lose its water control function, effectively extending the life of the float 400. This design extends the service life of the float and reduces the cleaning frequency. When the water level in the storage chamber 111 is insufficient, the user can add clean water to the water replenishment chamber 210 of the external water tank 200 in a timely manner. Since there is a one-way water passage 002 between the steam generating chamber 112 and the water replenishment chamber 210, which allows water to flow from the water replenishment chamber 210 to the steam generating chamber 112 and is controlled by the float 400, most of the excess water will enter the storage chamber 111 through the two-way water passage 001. At this time, the contaminants that have entered the water replenishment chamber 210 will be diluted or returned to the storage chamber 111, making the water in the water replenishment chamber 210 relatively cleaner. This ensures that the one-way water passage 002 prioritizes the use of cleaner water, further reducing the impact of contaminants on the float 400 and improving the service life of the float 400. Finally, this invention utilizes the buoyancy and gravity of the float 400 to control the opening and closing of the one-way water passage 002, eliminating the need for additional drive components and reducing production costs.

[0048] Specifically, in this embodiment, a portion of the top wall of the housing 110 is recessed downwards to form a cavity. The bottom wall of the cavity is provided with an annular partition rib 113. A steam generating chamber 112 is formed within the area surrounded by the partition rib 113, while the portion of the cavity located outside the partition rib 113 forms a water storage chamber 111. The heating element 120 forms the bottom wall of the steam generating chamber 112 to improve the heating rate of the water in the steam generating chamber 112. An external water tank 200 is located on the portion of the top wall of the housing outside the cavity. The wall of the water replenishment chamber 210 is provided with a protruding first insertion tube 211 and a second insertion tube. The first insertion tube 211 penetrates the side wall of the concave cavity and communicates with the water storage cavity 111. At this time, the first insertion tube 211 forms the aforementioned bidirectional water passage 001. The bottom wall of the water storage cavity 111 is provided with a connecting tube 114. The partition rib 113 is provided with a through hole 1130. One end of the connecting tube 114 is connected to the steam generating cavity 112 through the through hole 1130, and the other end is connected to the unidirectional water passage 002 through the second insertion tube 212. With this design, the connecting tube 114 can be hidden below the water storage cavity 111 to avoid it being exposed and affecting the appearance of the product. By surrounding the steam generating chamber 112 with the water storage chamber 111, the volume of the water storage chamber 111 can be increased while the volume of the steam generating chamber 112 can be reduced, so that the water in the steam generating chamber 112 can quickly generate steam and achieve the purpose of rapid steam output. At the same time, the increased volume of the water storage chamber 111 can also reduce the number of times water needs to be added. In addition, the annular partition rib 113 can also facilitate the processing and forming of the partition rib 113, thereby reducing the processing difficulty of the shell 110.

[0049] In this embodiment, the bidirectional water passage 001 is located near the bottom of the side wall of the water storage chamber 111. Since oil floats on the water surface, this design effectively prevents surface oil from entering the bidirectional water passage 001, keeping the water in the water replenishment chamber 210 clearer and cleaner.

[0050] In addition, such as Figures 3 to 7As shown, the base 100 in this embodiment also includes an installation groove 130 and a partition frame 500. The external water tank 200 includes a water tank body 201 and a water tank cover 202. The top of the water tank body 201 is open to form a water inlet for the water replenishment chamber 210. The water tank cover 202 can open or close the water inlet of the water tank body 201. An interval partition structure is provided between the installation groove 130 and the water replenishment chamber 210. The interval partition structure is the bottom wall of the water tank body 201. The installation groove 130 is located on one side of the outer surface of the bottom wall of the external water tank. A water passage is provided on the interval partition structure to connect the installation groove 130 and the water replenishment chamber 210. That is, the groove of the installation groove 130 is located on the bottom wall of the water tank body 201, and the groove of the installation groove 130 forms a water passage. In this way, the interval partition structure further achieves the separation and blocking of pollutants, etc. To improve the service life of the float 400, the mounting groove 130 can be positioned below the water supply chamber 210, with the bottom wall of the mounting groove 130 lower than the second insertion tube 212. The separator 500 is installed inside the mounting groove 130. Since the water in the steam generating chamber 112 evaporates quickly, the water in the steam generating chamber 112 will not flow into the mounting groove 130. This creates the aforementioned one-way water passage 002 between the separator 500 and the bottom wall of the mounting groove 130. The outer periphery of the partition frame 500 forms a circumferential seal with the side wall of the mounting groove 130, and this circumferential seal is higher than the second insertion tube 212 to prevent water in the water supply chamber 210 from flowing into the one-way water passage 002 through the gap between the outer periphery of the partition frame 500 and the side wall of the mounting groove 130. The partition frame 500 includes a top plate 510 and a water inlet 511 provided on the top plate 510. The water inlet 511 communicates with the water supply chamber 210, and the second insertion tube 212 forms a water outlet. The float 400 is located between the top plate 510 and the mounting groove 130. Between the bottom walls, the water inlet 511 is positioned above the float 400, so that the water inlet 511 can be opened and closed by the float 400 floating with the water level in the one-way water passage 002. In addition, since the float 400 and the partition 500 are located below the water replenishment chamber 210, it is also beneficial for the water in the water replenishment chamber 210 to flow to the one-way water passage 002. Furthermore, the water tank cover 202 can cover the water tank body 201, thereby concealing the mounting groove 130 and further improving the product's appearance.

[0051] To facilitate user cleaning of the interior of the mounting slot 130, the float 400, and the separator 500, in this embodiment, the separator 500 and the float 400 are detachably connected to form a float valve, which is detachably installed inside the mounting slot 130. This design allows the float 400 to be removed along with the separator 500 from the mounting slot 130, enabling the assembly and disassembly of the float valve from the mounting slot 130, as well as the assembly and disassembly of the various components of the float valve, and the cleaning of the mounting slot 130. This achieves the effects of no water retention, easy cleaning, and safety and hygiene.

[0052] Preferably, the partition frame 500 in this embodiment includes a plurality of circumferentially spaced and downwardly extending elastic buckles 520. There is a gap between the elastic buckles 520 and the side wall of the mounting groove 130. An annular sleeve 530 is provided between the upper end of the elastic buckle 520 and the top plate 510. An annular groove 531 is provided on the outer periphery of the annular sleeve 530. A sealing ring 600 is provided in the groove 531. The sealing ring 600 is interference-fitted with the side wall of the mounting groove 130. In this way, while achieving circumferential sealing between the partition frame 500 and the side wall of the mounting groove 130, the partition frame 500 and the mounting groove 130 can also be detachably connected. In this embodiment, a water passage hole 501 is formed between two adjacent elastic buckles 520. The elastic buckle 520 is provided with an inwardly extending buckle protrusion 521. The float 400 is limited between the buckle protrusion 521 and the top plate 510 with a water inlet 511. This design facilitates the assembly and disassembly of the float 400 and the partition frame 500, and also guides the float 400 to float through the elastic buckle 520, preventing the float 400 from floating and deviating and failing to close the water inlet 511. In addition, by limiting the float 400 to a lower position through the buckle protrusion 521, it is also ensured that when the float 400 is at its lowest position, a water inlet gap is formed between the float 400 and the bottom wall of the mounting groove 130. Thus, when the float 400 is at its lowest position, water flowing into the one-way water passage channel 002 can flow into the water inlet gap, so that the float 400 is buoyed and floats up, thereby ensuring that the float 400 can close the water inlet to control the water.

[0053] In this embodiment, there are two elastic buckles 520. In order to ensure the guiding effect on the float 400, a guide rib 540 is provided between the two elastic buckles 520. The guide rib 540 and the elastic buckle 520 are spaced apart so that a water passage hole 501 is also formed between them. The guide rib 540 is also provided with multiple water passage holes 501.

[0054] like Figure 2 and Figure 3 As shown, in order to facilitate the user to disassemble the float valve from the mounting groove 130, the bottom wall of the water tank body 201 in this embodiment is provided with a protruding rib 203 surrounding the mounting groove 130. The protruding rib 203 supports the top plate 510 so that there is a gap between the top plate 510 and the bottom wall of the water tank body 201. In this way, when the user disassembles the float valve, he can insert his fingernail or finger into the gap and push the top plate 510 upward to achieve the overall disassembly of the float valve.

[0055] It is understood that in other embodiments of this utility model, the divider may also include only an integrally formed top plate and an annular sleeve. The outer periphery of the annular sleeve is provided with a sealing ring, which is interference-fitted with the side wall of the mounting groove. The top plate is provided with a water inlet. In this case, the float is guided up and down by the side wall of the mounting groove, and there is a water passage gap between the float and the side wall of the mounting groove.

[0056] Finally, as Figure 4 , Figure 6 and Figure 7 As shown, in order to improve the effect of the float 400 in closing the water inlet 511, a water inlet rubber ring 700 is also installed on the top plate 510 in this embodiment. The outer periphery of the water inlet rubber ring 700 is provided with an annular groove 710. The part of the top plate 510 located around the water inlet 511 is inserted into the annular groove 710. The part of the water inlet rubber ring 700 located below the annular groove 710 is provided with an annular skirt 720. The skirt 720 can be stretched and deformed in the vertical direction. When the float 400 floats up, it can compress the skirt 720 to achieve complete closure of the water inlet 511.

[0057] The following embodiment will be based on Figure 8 This document explains the process of water level changes in each cavity of an electric steamer during use.

[0058] As shown in Figure a, in the initial state before operation, water can be added to the water storage chamber 111 or the water supply chamber 210. As shown in Figure b, as the amount of water added increases, the float 400 rises, and water flows into the steam generating chamber 112 through the second insertion pipe 212 and the connecting pipe 114. As shown in Figure c, as the amount of water flowing in further increases, the float 400 rises and presses against the water inlet rubber ring 700, closing the water inlet 511. At this time, the one-way water passage 002 is in the open state to cut off the water supply to the steam generating chamber 112. At this time, the steam generating chamber 112 only has a small amount of water for heating, thus quickly generating steam. As shown in Figure d, as the water in the steam generating chamber 112 continues to evaporate, the amount of water in the steam generating chamber 112 decreases, the water level drops, the float 400 falls accordingly, the water inlet 511 opens, and the one-way water passage 002 is in the connected state. Water in the water supply chamber 210 can enter the steam generating chamber 112 through the one-way water passage 002. The above process can occur repeatedly during the work process.

[0059] Therefore, this embodiment achieves the goal of heating only a small amount of water in the steam generating chamber 112, greatly shortening the steam generation time and achieving rapid steam output. After the operation is completed, the float valve can be removed, and the water stored in each chamber can be poured out, avoiding the problem of water accumulation.

[0060] It is understood that in other embodiments of this utility model, the partition ribs can also be arranged along the front and back to divide the interior of the concave cavity into two cavities, the left cavity being the steam generating cavity and the right cavity being the water storage cavity, and the external water tank being installed on the right side of the shell, so that the water storage cavity is located between the steam generating cavity and the external water tank.

[0061] Example 2

[0062] like Figures 9 to 11As shown, compared with Embodiment 1, the difference in this embodiment is that the partition structure in this embodiment is a vertically extending partition 204 located inside the external water tank. The partition 204 extends along the left-right direction of the housing 110 to divide the interior of the external water tank into front-to-back water replenishment chambers 210 and mounting slots 130. Since the existing external water tanks are relatively long, using the partition 204 to divide the interior of the external water tank into horizontally distributed water replenishment chambers 210 and mounting slots 130 can achieve the desired effect along the length of the external water tank. The modification of the housing 110 is minimal and the product modification cost is low. In addition, the partition 204 is provided with a water inlet 2041, which is set above the top plate of the partition frame 500. The water inlet 2041 forms a water passage to connect the installation groove 130 and the water supply chamber 210. This allows water in the water supply chamber 210 to enter the installation groove 130 through the water inlet 2041. The partition 204 further separates and blocks contaminants, thereby improving the working life of the float valve.

[0063] In this embodiment, the water tank cover 202 covers the water replenishment cavity 210 without obstructing the mounting groove 130. The opening of the mounting groove 130 is open and exposed on the outer surface of the base. The installation method of the partition frame 500, float 400 and mounting groove 130 can refer to the description in Embodiment 1. In addition, in this embodiment, the partition frame 500 is connected to the cover plate 800 by screws. The cover plate 800 covers the opening of the mounting groove 130, and a transition cavity is formed between the cover plate 800 and the partition frame 500, which connects the water replenishment cavity 210 and the one-way water passage 002. This design can prevent external debris from entering the mounting groove 130 and causing water contamination by covering the opening of the groove with the cover plate 800. It also allows the float valve to be removed by pulling the cover plate 800 without opening the water tank cover 202, thus enabling cleaning of the float valve and mounting groove 130, making the operation simpler.

[0064] It is understood that in other embodiments of this utility model, the opening of the mounting groove can also be covered by a water tank cover. This design can further improve the appearance of the product without the need for a cover plate.

[0065] It is understood that in other embodiments of this utility model, the spaced-partition structure is the housing of the base. The top of the portion of the housing located outside the concave cavity is recessed downward to form the mounting groove. That is, the mounting groove and the water tank are set independently. The side walls of the water replenishment cavity and the mounting groove are respectively provided with a first through hole and a second through hole. The first through hole and the second through hole are aligned and connected by making the side walls of the first through hole and the second through hole fit tightly together, or the first through hole and the second through hole are connected by a pipe. In this case, a water passage is formed inside the second through hole. The second through hole can further separate and block contaminants, thereby improving the working life of the float valve. The water tank cover can cover the opening of the water replenishment cavity and the mounting groove at the same time; or the water tank cover can cover the water replenishment cavity alone, while a cover plate is connected to the float valve so that the cover plate covers the groove.

[0066] Example 3

[0067] Compared to Embodiments 1 and 2, this embodiment differs in that: the base also includes a housing and a float shell exposed on the outer surface of the housing. A one-way water passage is formed inside the float shell, including an inlet and an outlet. The inlet is connected to the water supply chamber via a pipe, which is also connected to the bottom of the side wall of the water supply chamber. The outlet is connected to the steam generating chamber via a connecting pipe. The inlet is located above the float. A partition frame is installed inside the float shell and also has the inlet. Its installation method can refer to Embodiment 1. The float floats to open and close the inlet. This design eliminates the need to change the layout of the existing internal structure of the housing; only the float shell needs to be installed on the outer surface of the housing, thus reducing product modification costs. Furthermore, the float can be disassembled and assembled without opening the external water tank or housing, making it convenient for users to clean or replace the float.

[0068] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
