[0013] In the above-mentioned anti-flavor cross-contamination electric steamer, a cavity wall of the steam generating cavity is provided with a communication hole, and two adjacent steam generating cavities are connected through the communication hole.
[0014] In the above-mentioned anti-flavor electric steamer, the base includes a water holding chamber, a plurality of heating units are provided at the bottom of the water holding chamber, and a steam shield corresponding to the plurality of heating units is provided between the bottom wall of the water holding chamber and the lowest juice receiving tray, and the steam shield encloses the steam generating chamber.
[0015] Beneficial effects of the utility model:
[0016] 1. The second steam passage in the present invention includes an openable and closable steam passage equipped with a first steam valve and a normally open steam passage at an end. The normally open steam passage at the end communicates with the corresponding steam chamber. The openable and closable steam passage includes a steam conduit connecting two adjacent juice trays, which drives the first steam valve below it to open. Because the first steam valve of the openable and closable steam passage can only be opened when driven by the steam conduit, and the steam conduit is assembled downward, that is, the first steam valve will only open when it is pressed downward. Therefore, when a certain steam conduit and a certain juice tray are not assembled, the corresponding first steam valve is in a closed state. In this way, when the user omits certain juice trays and steam conduits to reduce the number of steam chambers (even if the number of steam chambers in the electric steamer is less than the maximum number of steam chambers and greater than one), it can still ensure that all steam chambers except the bottommost steam chamber have only one steam passage to introduce steam, allowing these steam chambers to slowly steam some food, thereby improving the user experience.
[0017] 2. A first steam valve is disposed within the steam duct. Multiple juice receiving trays include a middle juice receiving tray and a bottom juice receiving tray. One of the second steam passages has a steam supply passage located within the steam generating chamber. The remaining second steam passages also include steam supply passages located within the corresponding steam generating chamber and connected to the openable and closable steam passages. A second steam valve is disposed within the steam supply passage, and the steam duct drives the second steam valve to open. With this design, when the first steam valve is mounted on top of the steam duct and the steam duct drives the first steam valve in the adjacent lower steam duct to open, the second steam valve ensures that steam within the steam generating chamber can pass through the steam supply passage and into the steam duct on the bottom juice receiving tray. Furthermore, when the steaming lid is directly mounted on the bottom juice receiving tray, resulting in a single steaming chamber, all steam ducts above the bottom juice receiving tray are eliminated, allowing the second steam valve to be closed. This allows the steam chamber to have only one first steam passage for steam entry, enabling slow steaming of certain ingredients.
[0018] 4. The multiple juice receiving pans further include a middle juice receiving pan and a bottom juice receiving pan. The openable and closable steam passage includes steam ports provided on the middle juice receiving pan and the bottom juice receiving pan. The steam conduit connects the steam ports on two adjacent juice receiving pans. The first steam valve is provided in the steam port so that the steam conduit drives the first steam valve thereunder to open. When the steam generating chamber is opened, the steam in the steam generating chamber is opened, and the steam in the steam generating chamber is opened.
[0019] 5. The first steam valve comprises a valve body, an elastic member, and a valve stem. The valve body defines a continuous valve cavity, which forms part of the openable and closable steam passage. One end of the valve cavity has an inlet. The valve stem is floatingly mounted within the valve cavity. The elastic member drives the valve stem upward to close the inlet, while the steam conduit is used to drive the valve stem downward to open the inlet. With this design, when the steam conduit and / or juice tray are not connected to the upper end of the first steam valve, the valve stem, under the action of the elastic member, closes the inlet, thereby closing the steam passage. However, when the steam conduit and / or juice tray are attached, they drive the valve stem downward to open the inlet, thereby opening the openable and closable steam passage.
[0020] 6. The valve stem consists of a stem and a sealing portion. The sealing portion is sleeved on the lower end of the stem and is used to open and close the inlet. This design not only improves the sealing reliability of the inlet through the sealing portion, but also reduces the machining accuracy requirements of the stem.
[0021] 7. The first steam valve is mounted on the juice tray. The steam conduit drives the first steam valve on the adjacent juice tray below to open. The lower end of the steam conduit is inserted into the valve cavity, so that the valve body limits the horizontal position of the steam conduit. This design prevents horizontal displacement of the steam conduit, thereby ensuring reliable installation.
[0022] 8. The steamer assembly includes a steaming enclosure positioned between two adjacent saucepans. The enclosure and the two adjacent saucepans form a steaming chamber, and a steam duct is positioned at the corner of the adjacent side walls of the enclosure. This corner placement of the steam duct reduces the space constraints imposed by the duct on food placement, allowing the steaming chamber to accommodate a wider variety of food sizes, thus increasing the practicality of the steamer. It also allows users to more flexibly arrange food within the steaming chamber, fully utilizing the chamber and improving space efficiency.
[0023] 9. The steamer assembly also includes a steaming plate mounted on each juice collecting tray. A water collection area is formed between the steaming plate and the bottom wall of the juice collecting tray. The steaming plate is provided with an avoidance hole. The valve body passes through the avoidance hole, and the lower end of the steam duct is lower than the steaming plate. This design allows food to be placed on the steaming plate, thereby isolating the food from the juice on the juice collecting tray through the steaming plate, preventing the juice in the juice collecting tray from affecting the steaming effect of the electric steamer on the food. In addition, the valve body can prevent the juice in the juice collecting tray from entering the valve cavity, reducing the risk of odor contamination, thereby ensuring the steaming effect of the electric steamer on the food. In addition, the valve body passes through the avoidance hole. Since the distribution of the avoidance holes on the steaming plate is the same as the distribution of the steam passage, if the steaming plate is installed upside down, the valve body can interfere with the steaming plate, making it impossible to complete the assembly of the steaming plate, thereby prompting the steaming plate to be installed upside down, and achieving a foolproof effect on the steaming plate.
[0024] 10. The walls of the steam generating chambers are provided with connecting holes, connecting two adjacent steam generating chambers through the connecting holes. This design allows the steam in the steam generating chamber to flow into the adjacent steam generating chamber through the connecting holes to relieve pressure when the steam passage is blocked due to abnormal use or blockage of the second steam passage.
[0025] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[0041] The utility model provides an electric steamer that prevents odor from spreading, comprising a base and a steamer assembly arranged on the base, wherein the base is provided with a plurality of steam generating chambers, the steamer assembly comprises a plurality of independently arranged steaming chambers and a juice collecting tray forming the bottom wall of the steaming chamber, wherein one of the steam generating chambers is connected to the steaming chamber of the lowest layer through a first steam passage, and the remaining steam generating chambers are respectively connected to the remaining steaming chambers through independent second steam passages in a one-to-one correspondence, the second steam passage comprises an openable and closable steam passage provided with a first steam valve and a normally open steam passage at the end, the openable and closable steam passage comprises a steam conduit, and the steam conduit drives the first steam valve thereunder to open.
[0042] The second steam passage includes an openable and closable steam passage provided with a first steam valve and a normally open steam passage at the end. The normally open steam passage at the end is connected to the corresponding steam chamber. The openable and closable steam passage includes a steam conduit, which connects two adjacent juice trays. The steam conduit drives the first steam valve below it to open. Since the first steam valve of the openable and closable steam passage can only be opened when driven by the steam conduit, and the steam conduit is assembled downward, that is, the first steam valve will only open when it is pressed downward, when a certain steam conduit and a certain juice tray are not assembled, the corresponding first steam valve is in a closed state. In this way, when the user omits some juice trays and steam conduits to reduce the number of steam chambers (even if the number of steam chambers in the electric steamer is less than the maximum number of steam chambers and greater than one), it can be ensured that all steam chambers except the bottom steam chamber have only one steam passage to introduce steam, so that these steam chambers can slowly steam some food, thereby improving the user experience.

[0044] Example 1
[0045] like Figures 1 to 12 As shown, the anti-flavor electric steamer in this embodiment includes a base 100 and a steamer assembly arranged on the base 100, the base 100 is provided with a plurality of steam generating chambers 110, the steamer assembly includes a plurality of independently arranged steaming chambers 200 and a juice receiving tray 300 forming the bottom wall of the steaming chamber 200, and the "plurality" refers to three or more, one of the steam generating chambers 110 is connected to the steaming chamber 200 in the lowermost layer through a first steam passage, and the remaining steam generating chambers 110 are each connected to the remaining steaming chambers 200 in a one-to-one correspondence through an independent second steam passage, the second steam passage includes an openable and closable steam passage provided with a first steam valve 500 and an end normally open steam passage, the end normally open steam passage is located at the end of the second steam passage and is connected to the corresponding steaming chamber 200, the openable and closable steam passage includes a steam conduit 400, and the steam conduit 400 connects two adjacent juice receiving trays 300, the first steam valve 500 is provided on the juice collecting tray 300, and the steam duct 400 drives the first steam valve 500 on the adjacent lower juice collecting tray 300 to open. Since the steam duct 400 is assembled downward, that is, the first steam valve 500 will not open until it is subjected to downward pressing pressure. Therefore, when a certain steam duct 400 and a certain juice collecting tray are not assembled, the corresponding first steam valve 500 is in a closed state due to not being subjected to pressing pressure. In this way, when the user omits some juice collecting trays and steam ducts 400 to reduce the number of steaming chambers 200 (even if the number of steaming chambers 200 of the electric steamer is less than its maximum number of steaming chambers 200 and is greater than 1), it can also ensure that all steaming chambers except the bottom steaming chamber have only one steam passage to introduce steam, so that these steaming chambers 200 can slowly steam some food, thereby improving the user experience.
[0046] Specifically, the multiple juice receiving trays 300 in this embodiment include a bottom juice receiving tray, at least one middle juice receiving tray and a top juice receiving tray vertically spaced from bottom to top, each juice receiving tray is provided with a normally open steam outlet 310, wherein the normally open steam outlet 310 on the bottom juice receiving tray forms a first steam passage, and the normally open steam outlet 310 on the other juice receiving trays form the end of the end normally open steam passage. Except for the top juice receiving tray, each of the other juice receiving trays is further provided with at least one steam outlet 310 with a first steam valve 500 built in. In the second steam passage connected to the third steam chamber and above from the bottom to the top, the upper end of the uppermost steam conduit included therein is connected to the normally open steam outlet 310, and the two ends of the remaining steam conduits 400 are respectively connected to the steam outlet 310 with the first steam valve 500 built in on the upper and lower juice receiving trays 300. After assembly, the steam conduits 400 can press downward to open the first steam valve 500 on the adjacent lower juice receiving tray 300. With this design, when all the juice receiving trays 300 and steam conduits 400 are in use and correctly placed, the steam conduits 400 will drive the first steam valve 500 on the adjacent lower layer of the juice receiving tray 300 to open, so that the second steam passage is unblocked, so that the steam in the steam generating chamber 110 can enter the corresponding steaming chamber 200 through the second steam passage, playing a foolproof role; and when it is necessary to remove one or more layers of the juice receiving trays 300 and part of the steam conduits 400 for use, if the steam outlet 310 of a certain layer of the juice receiving tray 300 is provided with a first steam valve 500 and the upper end is connected to the corresponding steam conduit 40 0, the steam duct 400 will open the first steam valve 500 to open the steam outlet 310 to introduce steam into the upper steam duct 400. If the upper end of the steam outlet 310 with the first steam valve 500 on a certain layer of the juice receiving tray 300 is not connected to the corresponding steam duct 400, it will be in a closed state to prevent steam from entering the steaming cavity with the juice receiving tray as the bottom wall. Therefore, no matter whether the electric steamer uses one or less than the maximum number of steaming cavities, it can be ensured that each steaming cavity 200 has only one steam outlet 310 to introduce steam, so that all steaming cavities 200 can achieve slow steaming of food, thereby improving the experience.
[0047] For ease of understanding, the steamer assembly in this embodiment includes a steaming cover 600, three juice receiving trays 300 and two steaming enclosures 700. The three juice receiving trays 300 are arranged at intervals in the vertical direction. At this time, the number of the middle juice receiving tray is one, and the steaming enclosure 700 is placed between two adjacent juice receiving trays 300. The steaming enclosure 700 and the two adjacent juice receiving trays 300 form a steaming cavity 200. The steaming cover 600 is covered on the top juice receiving tray and forms the uppermost steaming cavity 200 between the top juice receiving tray 300. Thus, after the steamer assembly is assembled, it has three independent steaming cavities 200, and the base 100 is provided with three The three steam generating chambers 110 are distributed in a straight line along the length of the juice receiving tray 300. The normally open steam outlet 310 on the bottom juice receiving tray is located at the center thereof and is connected to the middle steam generating chamber 110. The remaining two steam generating chambers 110 are respectively connected to the remaining two steaming chambers 200 through a second steam passage, thereby preventing odor contamination. In addition, by distributing the three steam generating chambers 110 at intervals along the length of the juice receiving tray 300, the structure of the base 100 can be made more compact, saving the space occupied by the three steam generating chambers 110.
[0048] In this embodiment, the steam duct 400 is located at the corner of the adjacent side walls of the steam enclosure 700, and the corresponding steam outlet 310 is located at the corner of the juice receiving tray 300. This design, by locating the steam duct 400 at the corner, reduces the space restrictions imposed by the steam duct 400 on the placement of food, allowing the steam chamber 200 to accommodate a wider range of food specifications, thus making the electric steamer suitable for a wider range of usage scenarios and improving the practicality of the electric steamer. It also allows users to more flexibly arrange the layout of food within the steam chamber 200, making full use of the steam chamber 200 and improving the space utilization of the steam chamber 200.
[0049] Preferably, Figures 1 to 4 、 Figures 8 to 10As shown, a steam port 310 is provided at the left and right corners of the front side of the bottom juice receiving tray, and a first steam valve 500 is provided in each of the two steam ports 310.

The lower end of the steam shield 130 is sealed with the bottom of the water containing chamber, and the steam shield 130 encloses the steam generating chamber 110.
[0051] It is understandable that in other embodiments of the present invention, the steam baffle can also be integrally formed with the bottom wall of the water chamber, and the upper end of the steam baffle is sealed to the bottom wall of the lowest juice receiving tray.
[0052] It is understandable that in other embodiments of the present invention, the three steam shields may also be distributed in a V-shape, so that the three steam generating chambers are distributed in a V-shape.
[0053] Preferably, in this embodiment, the steam shield 130 includes three annular shield bodies 131, with adjacent annular shield bodies 131 connected by ribs. The bottom wall of the lowest juice receiving tray 300 is provided with a downwardly extending annular rib 330, which abuts the top of the middle annular shield body 131. The annular rib 330 forms part of the wall of the steam generating chamber 110. The annular rib 330 is provided with two connecting holes 331, one connecting hole 331 connecting the left steam generating chamber 110 with the middle steam generating chamber 110, and the other connecting hole 331 connecting the right steam generating chamber 110 with the middle steam generating chamber 110, so that the two adjacent steam generating chambers 110 are connected through the connecting holes 331. With this design, when the steam passage is blocked due to abnormal use or the steam port 310 is blocked, the steam in the steam generating chamber 110 can flow into the adjacent steam generating chamber 110 through the connecting holes 331, thereby achieving the effect of pressure relief.
[0054] like Figures 5 to 7 As shown, the first steam valve 500 in this embodiment includes a valve body 510, an elastic member 520 and a valve stem 530. The valve body 510 is provided with a valve cavity 511 which passes through from top to bottom. The valve cavity 511 forms a part of the steam passage that can be opened and closed. The valve body 510 is partially contracted inward to form a first constricted portion 512. The steam port 310 is provided on the bottom wall of the juice receiving tray 300. The first constricted portion 512 passes through the steam port 310 and is provided with a sealing ring between the steam port 310 and the wall portion of the steam port 310. The part of the valve body 510 located above the first constricted portion 512 is supported on the bottom wall of the juice receiving tray 300. The top surface of the valve body 510 is higher than the bottom wall of the juice receiving tray 300. The lower end of the valve cavity 511 forms an inlet. The valve stem 530 is vertically floatingly installed on the valve In the cavity 511, an air guide channel 531 is provided on the valve stem 530, the lower end of the air guide channel 531 is communicated with the inlet, the upper end of the air guide channel 531 is open, and the side of the air guide channel 531 is open and communicated with the valve cavity 511. The elastic member 520 is a spring or a silicone sleeve or a rubber sleeve, preferably a spring. A limit plate is provided on the top of the valve stem 530, the lower end of the spring is abutted against the top surface of the first constricted portion 512, and the upper end of the spring is abutted against the limit plate, so that the valve stem 530 is floatingly installed in the valve cavity 511. Under normal circumstances, the spring drives the valve stem 530 to move upward to close the inlet. After the lower end of the steam duct 400 is connected to the juice receiving tray 300, it can be used to drive the valve stem 530 to move downward to open the inlet. With this design, when the upper end of the steam outlet 310 is not connected to the steam conduit 400, the valve stem 530 closes the inlet under the action of the elastic member 520. When the steam conduit 400 is connected to the steam outlet 310, the valve stem 530 is driven downward to open the inlet, so that the inlet is connected to the upper steam conduit 400 through the valve cavity 511 and the air guide channel 531, so that steam enters the upper steam conduit 400 through the inlet and the air guide channel 531.
[0055] In normal operation, the valve stem 530, under the action of the elastic member 520, closes the inlet, i.e., the steam port 310. To enhance the sealing reliability of the valve stem 530 in closing the steam port 310, the valve stem 530 in this embodiment comprises a stem portion 532 and a sealing portion 533. The sealing portion 533 is an annular sealing sheet. The lower end of the stem portion 532 is provided with a slot, into which the inner ring of the sealing portion 533 fits. The portion of the stem portion 532 above the sealing portion 533 is provided with a plurality of gas guide channels 531. In normal operation, the sealing portion 533 closes the inlet. This design not only enhances the sealing reliability of the inlet through the sealing portion 533 but also reduces the machining precision requirements of the stem portion 532.
[0056] It can be understood that in other embodiments of the present invention, the inlet is a tapered mouth that contracts upward, and the lower end of the valve stem is provided with a cone head that cooperates with the tapered mouth. Under normal circumstances, the cone head and the tapered mouth cooperate to block the steam port. Such a design can eliminate the sealing part and simplify the structure of the steam valve.
[0057] To facilitate user assembly of the steamer assembly, the upper end of the steam conduit 400 in this embodiment is fixed to the upper juice tray 300 with screws. A portion of the upper end of the steam conduit 400 communicates with the normally open steam port on the upper juice tray 300, while another portion of the upper end of the steam conduit 400 sleeves over the valve body 510. A steam clearance exists between the steam conduit 400 and the valve stem 530. This design allows the steam conduit 400 to be pre-assembled on the upper juice tray 300 at the factory, eliminating the need for user assembly, thus enhancing the user experience. Furthermore, the steam clearance ensures communication between the lower steam conduit 400 and the corresponding inlet of the valve body 510, allowing steam to reach the inlet. Preferably, the steaming enclosure 700 is fixedly connected to the upper juice collecting tray 300 by screws, so that the steaming enclosure 700, the juice collecting tray 300 fixed on the top of the steaming enclosure 700, and the steam duct 400 connected to the juice collecting tray 300 form a steamer. In this way, when using, the user can omit the assembly of the steaming enclosure 700 and the upper juice collecting tray 300, thereby further improving the user experience.
[0058] In this embodiment, when the lower end of the steam conduit 400 is connected to the juice receiving tray 300, it is preferably inserted into the valve cavity 511. Specifically, the lower end of the steam conduit 400 is provided with a second, inwardly contracting portion, which is inserted into the valve cavity 511. The portion of the steam conduit 400 above the second, contracted portion is supported on the valve body 510, thereby allowing the valve body 510 to horizontally limit the steam conduit 400. This design prevents horizontal displacement of the steam conduit 400, thereby ensuring reliable communication between the steam conduit 400 and the upper air guide channel 531 of the lower steam valve.
[0059] It can be understood that in other embodiments of the present invention, the lower end of the steam conduit can also be mounted on the outside of the valve body, and a pressing rib is provided on the inner side of the steam conduit. After the steam conduit is mounted on the lower juice receiving tray, the pressing rib presses the valve stem downward to open the steam outlet.
[0060] In addition, the steamer assembly in this embodiment also includes a steaming plate 800 mounted on each juice receiving tray 300. The steaming plate 800 is a porous plate. A water collection area is formed between the steaming plate 800 and the bottom wall of the juice receiving tray 300. The steaming plate 800 is provided with an avoidance hole 810. The valve body 510 is set through the avoidance hole 810. The lower end of the steam duct 400 is set lower than the steaming plate 800. The bottom wall of the juice receiving tray 300 is also provided with an upwardly arched boss. The steam outlet 310 is provided on the top wall of the boss, and the boss also passes through the avoidance hole 810. The hole 810 is set. With this design, the food can be placed on the steaming plate 800, so that the food and the juice on the juice receiving tray 300 are isolated through the steaming plate 800, preventing the juice in the juice receiving tray 300 from affecting the steaming effect of the electric steamer on the food; in addition, the valve body 510 can prevent the juice in the juice receiving tray 300 from entering the valve cavity 511, and the boss can prevent the juice in the juice receiving tray 300 from entering the steam port 310, reducing the risk of cross-flavoring, thus ensuring the safety of the electric steamer. The steaming pot has a steaming effect on the food; in addition, the valve body 510 is provided with the avoidance hole 810. Since the distribution of the avoidance holes 810 on the steaming plate 800 is the same as the distribution of the steam passage, when the steaming plate 800 is installed upside down, the valve body 510 can interfere with the steaming plate 800 and make it impossible to complete the assembly of the steaming plate 800, thereby playing the effect of prompting the steaming plate 800 to be installed upside down, and realizing the anti-mistake effect on the steaming plate 800; finally, the lower end of the steam guide 400 is arranged below the steaming plate 800. When the steam guide 400 is installed upside down, After the upper juice collecting tray 300 and the steaming enclosure 700 are pre-installed, when the installation position of the steaming enclosure 700 is incorrect, the lower end surface of the steam duct 400 will conflict with the steaming plate 800, so that the steaming enclosure 700 cannot be installed, thereby playing a fool-proof role. In this way, the steaming plate 800 can prevent the steaming enclosure 700 from being positioned incorrectly while playing an isolation role, without the need to add other structures to limit the position of the steaming enclosure 700, thereby simplifying the structure of the electric steamer and making the electric steamer more convenient to manufacture.
[0061] When the user only needs two steaming chambers 200 to steam food, the upper steamer (i.e., the top sauce tray, the upper steaming enclosure 700, and the steam conduit 400 fixedly connected to the top sauce tray) can be removed. Figure 11As shown, at this time, the first steam valve 500 on the right side of the middle juice receiving tray is in a state of closing the steam port 310. The steam in the right steam generating chamber 110 cannot enter the upper steam chamber 200. The steam in the left steam generating chamber 110 enters the upper steam chamber 200 through the left normally-open steam port 310. The lower steam chamber 200 is connected to the middle steam generating chamber 110 through the steam port 310 on the bottom juice receiving tray. At this time, both the upper and lower steam chambers 200 have only one steam passage to introduce steam. That is, the amount of steam entering the two steam chambers 200 per unit time is small, which can achieve slow steaming.
[0062] The lower steamer (i.e., the middle juice tray, the lower steaming enclosure 700, and the steam conduit 400 fixedly connected to the middle juice tray 300) can also be removed. Figure 12 As shown, at this time, the first steam valve 500 on the left side of the bottom juice receiving tray closes the steam outlet 310, and the first steam valve 500 on the right side of the bottom juice receiving tray 300 is driven by the steam duct 400 to open the steam outlet 310 on the right side of the bottom juice receiving tray 300, and the steam in the right steam generating chamber 110 can enter the upper steaming chamber 200 through the steam duct 400, and the lower steaming chamber 200 is connected to the middle steam generating chamber 110 through the steam outlet 310 on the bottom juice receiving tray. At this time, both the upper and lower steaming chambers 200 have only one steam passage to introduce steam, that is, the amount of steam entering the two steaming chambers 200 per unit time is small, and slow steaming can be achieved, thereby improving the experience.
[0063] When the user only needs one steaming chamber 200 to steam ingredients, the upper steamer (i.e., the top juice receiving tray, the upper steaming enclosure 700, and the steam duct 400 fixedly connected to the top juice receiving tray) and the lower steamer (i.e., the middle juice receiving tray, the lower steaming enclosure 700, and the steam duct 400 fixedly connected to the middle juice receiving tray 300) can be removed. At this time, the steaming cover 600 is directly covered on the bottom juice receiving tray. At this time, the first steam valves 500 on the left and right sides of the bottom juice receiving tray 300 are both in a closed state. The steaming chamber 200 has only one first steam passage for letting in steam, i.e., the amount of steam entering per unit time is small, so slow steaming in a single-chamber state can be achieved, thereby improving the experience.
[0064] Example 2
[0065] Compared with the first embodiment, the difference of this embodiment is that the first steam valve in this embodiment is installed on the top of the steam conduit. Figure 8Taking the three steaming chambers in the middle as an example, a first steam valve is installed on the top of the lower left steam duct 400, and the tops of the other two steam ducts 400 are normally open and connected to the normally open steam inlet. When the steamer assembly has three steaming chambers 200, the steam duct on the lower left is connected to the steam generating chamber on the left, and the steam duct 400 on the upper left passes through the steam inlet of the middle juice receiving tray and is inserted into the steam duct on the lower left to drive the first steam valve inside the lower left steam duct to open, and then the steam duct on the lower left is connected to the steam duct on the upper left through the steam inlet on the middle juice receiving tray. The structure of the first steam valve can be set with reference to Example 1. In order to realize that the upper left steam duct drives the first steam valve inside the lower left steam duct to open, the bottom of the upper left steam duct is inserted into the lower left steam duct and the valve stem is pressed downward to open the inlet.
[0066] It should be noted that the openable and closable steam passage of the second steam passage on the right is a steam supply passage arranged in the steam generating chamber, that is, the steam generating chamber on the right is provided with a steam supply passage connected to the steam outlet at the right corner of the bottom juice collecting plate, and a second steam valve is provided in the steam supply passage. Here, the second steam valve and the first steam valve have the same structure, so that the steam duct on the right can drive the first steam valve below to open, so that the steam generating chamber on the right is connected with the steam duct on the right, and the second steam passage on the left also includes a steam supply passage provided in the steam generating chamber on the left and connected to the openable and closable steam passage in the second steam passage on the left, and a second steam valve is provided in the steam supply passage, and the steam duct on the lower left drives the second steam valve to open. With this design, when three steaming chambers are used, the second steam valve is designed to ensure that the steam in the steam generating chamber can enter the lower left steam duct and the right steam duct on the bottom juice collecting tray through the steam supply channel; in addition, when the steaming cover is directly covered on the bottom juice collecting tray so that the electric steamer has only one steaming chamber, since all the steam ducts on the upper side of the bottom juice collecting tray are omitted, the second steam valve can be closed, so that at this time the steaming chamber has only one first steam passage to introduce steam, that is, the amount of steam entering the steaming chamber per unit time is less, so that some foods can be slowly steamed.
[0067] In addition, when the electric steamer in this embodiment uses two steaming chambers, for example, when the user removes the lower steaming surround, the middle juice receiving tray and the two steam ducts on the lower side so that the electric steamer has two upper and lower steaming chambers, the upper steaming chamber has only one left end that is normally open for steam passage to introduce steam, while the lower steaming chamber introduces steam through the first steam passage, thereby ensuring that both the upper and lower steaming chambers can slow-steam some ingredients, thereby improving the user experience.
[0068] When the user removes the upper steaming enclosure, the top juice tray and the steam duct on the upper left side so that the electric steamer has two upper and lower steaming chambers, the upper steaming chamber has only one normally open steam passage at the right end to introduce steam, while the lower steaming chamber introduces steam through the first steam passage, thereby ensuring that both the upper and lower steaming chambers can slow-steam some ingredients, thereby improving the user experience.
[0069] It is understandable that in other embodiments of the present invention, the steam supply channel in the steam generating chamber on the left may not be provided with a second steam valve. In this case, the steam supply channel remains normally open. In this way, when the steaming cover is directly covered on the bottom juice collecting tray so that the electric steamer has only one steaming chamber, the steaming chamber has a first steam passage and the steam supply channel on the left to introduce steam, so as to achieve rapid steaming of the food, and thus can steam some quick-steaming food.
[0070] It can be understood that in other embodiments of the present invention, when the first steam valve is arranged in the steam duct and in the steam supply channel, the first steam valve of the adjacent lower layer can also be driven to open by the juice receiving tray and / or the steaming plate arranged on the juice receiving tray.
[0071] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are intended to be included within the scope of the claims.
